Thu Jul 3 20:36:19 1997 Nanbor Wang * performance-tests/Misc/childbirth_time.cpp: Changed the parameter type of "Profiler" from int to size_t to make g++ happy. Thu Jul 03 20:03:18 1997 David L. Levine * ace/Reactor.cpp (remove_handler): added ACE_UNUSED_ARG when NSIG != 0. Wed Jul 2 23:41:43 1997 Nanbor Wang * performance-tests/Misc/childbirth_time.cpp: Fixed some typos. Wed Jul 2 23:13:10 1997 Douglas C. Schmidt * performance-tests/Misc/childbirth_time.cpp: Revised the code to use ACE programming style. Wed Jul 02 23:02:24 1997 Douglas C. Schmidt * ACE version 4.2.15, released Wed Jul 02 23:02:24 1997. Wed Jul 2 22:23:49 1997 Douglas C. Schmidt * ace/Service_Config.cpp: Used the new ACE_LACKS_UNIX_SIGNALS macro to reduce the #ifdef complexity somewhat. * ace/config-{chorus,win32-common}.h: Added #define for ACE_LACKS_UNIX_SIGNALS. * ace/OS.h: If a platform (e.g., Chorus) doesn't support signals then #define NSIG 0. * ace/Reactor.cpp: Chorus does not support signals. Make the call to register/remove_handler(sig_set, evnet_handler) return succesfully so that some of the examples and test programs do not need to be changed. Thanks to Wei Chiang for this. * ace/config-chorus.h: Added a new macro for ACE_LACKS_NAMED_POSIX_SEM to handle Chorus. Thanks to Wei Chiang for this. * ace/OS.i: Define macros ACE_PTHREAD_CLEANUP_* so that the related code does not need to be surrounded with #ifdefs. Thanks to Wei Chiang for this. * ace/OS.i: Chorus does not support named semaphores. The code that to do with names in sema_init() and sema_destory() is therefore disabled. Thanks to Wei Chiang for this. * ace/config-chorus.h: Added support for ACE_LACKS_PTHREAD_CLEANUP and ACE_HAS_POSIX_SEM to the Chorus port. Thanks to Wei Chiang for this. Wed Jul 2 17:37:09 1997 Douglas C. Schmidt * ace/Hash_Map_Manager.cpp: Clarified the behavior of close_i() a bit more. Wed Jul 2 09:54:36 1997 Douglas C. Schmidt * ace/Hash_Map_Manager.cpp: Fixed a couple more size_t->u_long conversions for ACE_Hash_Map_Manager::hash(). This didn't harm anything but it's good to be consistent. Wed Jul 2 16:46:59 1997 Nanbor Wang * performance-tests/Misc/childbirth_time.cpp: Added this program to measure child process/thread creation mechanisms on various platforms. Native thread creation test only supports Solaris and NT threads so far. But you can still use ACE_OS::thr_create method on your platform if not supported. Wed Jul 2 15:59:53 1997 Darrell Brunsch * ace/High_Res_Timer.cpp: Created a function get_registry_scale_factor that finds out the speed of the processor using the NT registry (in megahertz). This means that ACE_High_Res_Timers should automatically get the correct scale factor. * tests/Timer_Queue_Test.cpp: Removed the call to get_env_global_scale_factor(). Wed Jul 2 15:39:33 1997 Tim H. Harrison * ace/Process.cpp: Modified spawn to check for the NO_EXEC flag after forking on UNIX. If it's set, spawn returns the child pid without exec'ing. Updated the NT version to always return the child pid on success. Wed Jul 02 10:55:23 1997 David L. Levine * tests/SPIPE_Test.cpp,UPIPE_SAP_Test.cpp: tweaked the static functions a bit to avoid warnings about unused statics on VxWorks. Wed Jul 02 00:16:07 1997 Douglas C. Schmidt * ACE version 4.2.14, released Wed Jul 02 00:16:07 1997. Tue Jul 1 22:49:58 1997 Douglas C. Schmidt * ace/Strategies_T.h: Changed the return value of all the hash() methods to be u_long. * tests/Map_Manager_Test.cpp (hash): Changed the return value of all the hash() methods to be u_long. * ace/SString.cpp: Changed the return value of all the hash() methods to be u_long. * ace/Hash_Map_Manager: Changed the return value of hash() to return a u_long in order to (1) be consistent with the return value of hash_pjw() and (2) give the maximal range for the hash function. Thanks to Marina Spivak for reporting this. Tue Jul 01 14:47:22 1997 David L. Levine * ace/High_Res_Timer.{h,i} (gettime): use gettime () static function to wrap all calls to ACE_OS::gethrtime (). On ACE_WIN32, if the global scale factor has not been set, then gettime () uses ACE_OS::gettimeofday () instead of ACE_OS::gethrtime (), because gettimeofday doesn't need the scale factor. Mon Jun 30 17:28:53 1997 Douglas C. Schmidt * Makefile (RELEASE_FILES): Removed the rpc++ directory from the main release since this doesn't seem to be widely used and the GPL copyleft confuses people. Mon Jun 30 15:08:04 1997 David L. Levine * include/makeinclude/platform_vxworks5.x_g++.GNU: added -lgcc to LDFLAGS. Mon Jun 30 12:00:02 1997 Douglas C. Schmidt * ACE version 4.2.13, released Mon Jun 30 12:00:02 1997. Sat Jun 28 08:27:27 1997 David L. Levine * ace/OS.h: added definitions of ACE_SHLIB_HANDLE and ACE_DEFAULT_SHLIB_MODE on platforms other than ACE_HAS_SVR4_DYNAMIC_LINKING and hpux. * ace/OS.i: split definitions of ACE_OS::cond_* member functions into two: for ACE_WIN32/VXWORKS and all others. That allows us to break the circular dependencies between those functions and the ACE_OS::sema_* member functions. * ace/Svc_Conf_y.cpp: commented out unused args and wrapped assignments in "if" conditionals with parenthesis to avoid g++ warnings. * ace/{ACE,INET_Addr,OS}.cpp (VxWorks only): added ACE_UNUSED_ARG calls. * ace/Parse_Node.cpp (ACE_Stream_Node,ACE_Dynamic_Node,ACE_Dummy_Node constructors): reordered initializers to match declaration order. * ace/Profile_Timer.h (elapsed_time): commented out unused arg "et". * ace/Read_Buffer.cpp (rec_read): initialized local variable "c" to make sure that it is always defined before use. * ace/SPIPE_Acceptor.cpp (remove): don't declare local variable "result" if ! ACE_HAS_STREAM_PIPES, because it's not used in that case. * ace/config-vxworks5.x-g++.h: added ACE_LACKS_IOSTREAM_FX, ACE_LACKS_LINEBUFFERED_STREAMBUF, and ACE_LACKS_SIGNED_CHAR. * ace/IOStream_T.h (ipfx): comment out unused variable "need". * platform_vxworks5.2_g++.GNU: added -Wall now that the ACE library builds cleanly with it. * platform_vxworks5.x_g{++,hs}.GNU: renamed 5.x instead of 5.2. * netsvcs/lib/Token_Handler.cpp: reordered initializers to match declaration order. * tests/SV_Shared_Memory_Test.cpp: moved template specializations so that they're not done on platforms that don't support SV IPC. * examples/IOStream/client/iostream_client.cpp, examples/IOStream/server/iostream_server.cpp: use ACE_HAS_STRING_CLASS rather than __GNUC__ to determine whether the platform has a String class. Fri Jun 27 13:10:46 1997 Douglas C. Schmidt * ace: Changed the name of config-vxworks5.2-g++.h to config-vxworks5.x-g++.h since it works with 5.2 and 5.3. * examples/Mem_Map/IO-tests/IO_Test.cpp: Fixed some bugs that were preventing this from running correctly. Fri Jun 27 13:37:37 1997 Steve Huston * ace/Svc_Conf.y: Finished the sanity checks started below. Fri Jun 27 11:55:13 1997 Darrell Brunsch * ace/Timer_Queue_T.cpp: added a check for an empty queue in expire Fri Jun 27 07:53:58 1997 David L. Levine * tests/Message_Queue_Notifications_Test.cpp (handle_output, handle_exception,main): added ACE_UNUSED_ARG (fd) to avoid compilation warnings about unused arguments. Fri Jun 27 01:08:54 1997 Douglas C. Schmidt * ace/Connector.cpp (create_AST): Replaced the gratuitous #ifdef for ACE_WIN32 and EXCEPT_MASK with the new CONNECT_MASK. This is much cleaner! * ace/Event_Handler.h: Added a new CONNECT_MASK that defaults to READ_MASK | WRITE_MASK (with | EXCEPT_MASK thrown in for Win32). Thanks to Irfan for this suggestion. Thu Jun 26 19:53:11 1997 Nanbor Wang * ace/OS.i (strtok_r): Added check on a null string so we won't go past the end of a string. * performance-tests/Misc/context_switch_time.cpp (main): Added get_env_gloval_scale_factor() at the very beginning so that high resolution timer can return correct time in millisecond. Thu Jun 26 15:29:55 1997 Darrell Brunsch * tests/Timer_Queue_Test.cpp: Changed the random scheduling to use past times instead of future time. This should fix some unusual behavior of this test. Thanks to Gonzalo A. Diethelm for reporting this. Thu Jun 26 12:38:16 1997 Douglas C. Schmidt * ACE version 4.2.12, released Thu Jun 26 12:38:16 1997. Thu Jun 26 01:11:10 1997 Douglas C. Schmidt * ace/Svc_Conf.y: Added some sanity checks to make sure we don't segfault when things go wrong during the svc.conf file parsing. Thanks to Steve Huston for this suggestion. Thu Jun 26 08:36:37 1997 David L. Levine * Makefile: fix UPTODATE check (for release target) by not running it in a sub-shell. Also, added ACE-lessons.html to RELEASE_FILES. * performance-tests/Misc/context_switch_time.cpp: use same priority values on Win32 platforms as on Solaris, because thread priority increases with increasing priority values on both of those platforms. Thu Jun 26 01:34:46 1997 Nanbor Wang * performance-tests/Misc/misc.{mak,mdp}: Added makefile for NT. * ace/{FILE,DEV}.{h,i}: Added the disable(int signum) function to prevent NT from disabling a FILE/DEV using socket calls. Wed Jun 25 12:59:00 1997 * ace/Synch_T.h (ACE_SYNCH_PROCESS_MUTEX and ACE_SYNCH_NULL_MUTEX): Added new template typedef to the list. * tests/Message_Queue_Notifications_Test.cpp: New test for demonstrating notification qualities of Message_Queue. * ace/Strategies.h: Added accessors to these classes to make them more usable. Wed Jun 25 10:47:34 1997 Steve Huston * ace/Parse_Node.cpp: Insure that ACE_Object_Node::symbol(void) returns 0 if the underlying shared library can't be loaded. * ace/OS.h: Added a new type, ACE_SHLIB_HANDLE to allow dynamic linking using correct types on all platforms that support it. Also added a const ACE_SHLIB_DEFAULT_MODE for the 'mode' argument when doing a dlopen-like operation. Moved the ACE_OSCALL_* macros to this file from OS.i * ace/OS.i: Moved ACE_OSCALL_* macros out of here and into OS.h. Added support for dlopen/close/sym/error on HP-UX. Note - the Service_Configurator tests do not run yet on HP - I'm working on that. * ace/Service_Record.{h, i, cpp}: Use new ACE_SHLIB_HANDLE type for dynamic loading operations. * ace/Parse_Node.{h, cpp}: Use new ACE_SHLIB_HANDLE where appropriate. * ace/Strategies_T.cpp: Use new ACE_SHLIB_HANDLE type. Wed Jun 25 02:36:05 1997 Nanbor Wang * ace/OS.i (gmtime_r): Modified the implementation of gmtime_r when OS doesn't provide one. Notice that the implementation only simulate the semantic and is not thread-safe. * ace/OS.h: Moved definition of ACE_SHLIB_HANDLE typedef and ACE_DEFAULT_SHLIB_MODE global variable for Win32 to where it belongs. * ace/OS.i: Changed the return type of dlopen() when ACE_HAS_UNICODE to ACE_SHLIB_HANDLE. * ace/OS.{h,i}: Moved ACE_OSCALL and ACE_OSCALL_RETURN for WIN32 from OS.i to OS.h. Wed Jun 25 01:23:58 1997 Nanbor Wang * ace/OS.i (strtok_r): Modified the implementation when OS does not provide reentrant strtok_r so that our imp. comforms with the semantic of strtok_r (). Wed Jun 25 00:37:56 1997 Douglas C. Schmidt * ACE version 4.2.11, released Wed Jun 25 00:37:56 1997. Tue Jun 24 21:30:53 1997 David L. Levine * ace/Svc_Conf_y.cpp: commented out unused args and wrapped assignments in "if" conditionals with parenthesis to avoid g++ warnings. Tue Jun 24 18:15:46 1997 Nanbor Wang * ace/Reactor.cpp (wait_for_multiple_events): Modified the way to manipulate timeout value so that we can differentiate when there are timeout events to be handle from no timer and we want to wait indefinitely. Tue Jun 24 16:52:22 1997 David L. Levine * ace/OS.h: reverted ACE_hrtime_t to unsigned __int64 with VC++. This might break something, but we need to know what. Tue Jun 24 16:38:52 1997 Darrell Brunsch * Added Visual C++ 5.0 specific workspace (.dsw) and project (.dsp) files to both the ace and tests subdirectory. ACE.DSW in the root directory contains all the project files, so a batch build should be able to build all the project files. Tue Jun 24 14:27:47 1997 Darrell Brunsch * ace/Timer_{Hash,Heap,List,Wheel}_T.cpp: Changed cancel (type..) to call cancellation() even if there are no timers to cancel. This causes the correct behavior of calling handle_close () during expire when handle_timeout() returns -1. Thanks to Hamutal Yanay for pointing this out. * tests/Timer_Queue_Test.cpp: Updated to correctly test this. Tue Jun 24 13:02:51 1997 David L. Levine * ace/SString.h (ACE_SString ctor): changed "allocator" to "alloc". Thanks to Brian Mendel for reporting this. Tue Jun 24 12:58:28 1997 James C Hu * include/makeinclude/platform_irix6.4*: Shuts up useless warnings about multiply defined template instances. Tue Jun 24 12:50:52 1997 Douglas C. Schmidt * ACE version 4.2.10, released Tue Jun 24 12:50:52 1997. Tue Jun 24 00:44:30 1997 Nanbor Wang * ace/SPIPE.{h,i}: Added the disable(int signum) function to prevent NT from disabling an SPIPE using socket calls. Mon Jun 23 22:14:39 1997 Douglas C. Schmidt * ace/Svc_Conf*: Changed the name of the YYSTYPE field ACE_Static_Node_ to static_node_ to be consistent with the other fields. Mon Jun 23 18:28:55 1997 David L. Levine * ace/ACE.cpp: added auto_basic_array_ptr specialization. * ace/Service_Config.cpp, tests/Future_Test.cpp, examples/Threads/future[12].cpp: added auto_basic_ptr specializations. * include/makeinclude/platform_vxworks5.2_g++.GNU: reworked to supported different targets, instead of only PowerPC. Mon Jun 23 16:06:35 1997 James C. Hu * ace/OS.i: Moved definition of sema_* methods to follow cond_* methods to remove compiler warnings on SGI. Mon Jun 23 09:42:08 1997 Darrell Brunsch * tests/Timer_Queue_Test.cpp: added testing for cancellation during expire (when of handle_timeout() in an event handler returning -1). Mon Jun 23 09:18:39 1997 David L. Levine * Makefile: added up-to-date check for "make release" from /project/adaptive/ACE_wrappers. Also, "make release" now adds release entry to latest ChangeLog. * ace/Makefile: build shared library before static library. This appears to fix a problem with Sun C++ 4.{1,2} possibly related to its template instantiation scheme. If the static library is built first, then .shobj/Reactor.so and .shobj/Timer_Hash.so (and possibly others) fail to build due to ACE_TimeValue::normalize () "relocations remain against allocatable but non-writable sections". Thanks to Steve Huston and Satoshi Ueno for reporting this, and to Satoshi for verifying the fix. * ace/ACE.cpp (terminate_process): removed used of ACE_OSCALL_RETURN macro because its defined in OS.i, and so not available if inlining is disabled. * ace/Auto_Ptr.{h,i}: made "p_" protected instead of private so that it can be accessed with the new class arrangement. Also, made the auto_array_ptr operator-> const. * ace/Sched_Params.cpp (previous_priority, VxWorks only): removed ACE_UNUSED_ARG (policy) because policy is used in this function. * netsvcs/lib/TS_Clerk_Handler.cpp (parse_args): wrapped TCHAR argument to sizeof in parenthesis. Mon Jun 23 09:12:04 1997 Nanbor Wang * ace/Auto_Ptr.i (auto_array_ptr): Fixed a typo. Mon Jun 23 08:03:46 1997 Darrell Brunsch * ace/Auto_Ptr.h: changed inheritance of auto_basic_array_ptr in auto_array_ptr to include the template parameter X. * ace/IOStream_T.i: removed default parameter in the definition of ACE_Streambut_T::recv_n() and ACE_SOCK_Dgram_SC::recv_n() Mon Jun 23 01:13:15 1997 * ace/OS.cpp (fork_exec): Fixed the usage of ACE_WIDE_STRING. * test_registry_iterator.cpp (main): Fixed the usage of ACE_WIDE_STRING. * netsvcs/lib/TS_Clerk_Handler.cpp (parse_args): Fixed the usage of ACE_WIDE_STRING. * ace/Auto_Ptr.h: Added support for basic types by seperating the auto_ptr classes into two. One that requires the -> operator support and the other that does not. The former inherits from the latter. * ace/{FILE,DEV,SPIPE}_Addr.h: Added support for multibyte and wide character addr_to_string and string_to_addr functionality. * ace/Connector.cpp && ace/Acceptor.cpp (info): Fixed sizeof bug. * examples/Connection/blocking/SPIPE: Added UNICODE support for this example. * ace/OS.h: Added new macro ACE_MULTIBYTE_STRING. * ace/ACE.cpp (terminate_process): Fixed unused args errors. Sun Jun 22 09:58:36 1997 Douglas C. Schmidt * Released version 4.2.9 for testing. * ace/Log_Msg.cpp (open): Changed the use of ACE_LOG_MSG-> within the open() method to use this-> in order to avoid deadlocks. Thanks to Per Andersson for reporting this. * ace/ACE.cpp: Changed the use of __SVR4 and __unix to sparc and unix to work better with various UNIX environments. Thanks to Michael R. MacFaden for these changes. * ace/Handle_Set.cpp (count_bits): Added special code to handle the case where fdmask is typedef'd as a long rather than an int. Thanks to Eric Newton and James Johnson for reporting this. * ace/IOStream.h: Changed the name of QuotedString to ACE_Quoted_String to be consistent with the ACE naming scheme. Thanks to James Johnson for suggesting this. * ace/IOStream_T.i: Added this new file to split off the inlined code from the header file. * ace/ACE.cpp (terminate_process): Remove the ACE_UNUSED_ARG(signum) from terminate_process(). Thanks to Wei Chiang for reporting this. Sun Jun 22 17:19:18 1997 David L. Levine * examples/Threads/process_manager.cpp (main): replaced call to kill with terminate. Sat Jun 21 10:48:34 1997 Douglas C. Schmidt * examples/Reactor/FIFO: Added a new example that illustrates how the Reactor and the FIFO wrappers work together. Thanks to Johannes Gutleber for sending this. * tests/Time_Service_Test.cpp (main): Replaced the kill() call with the terminate() call since kill() isn't portable across platforms. * ace/Process: The kill() method on this class was being used incorrectly. I've created a new method called terminate() that terminates the process. * ace/Process_Manager: Renamed the kill() method to terminate() and updated the implementation to use the new ACE::terminate_process() call. * ace/ACE: Moved the incorrect Win32 and Chorus implementations of ACE_OS::kill() and put them in a new static method called ACE::terminate_process(). * ace/ACE: Changed the name of the is_process_active() to the more concise process_active(). * ace/OS.i: Added an implementation of ACE_OS::kill() for Chorus. Note that this doesn't behave as UNIX does -- it kills the process id rather than sending a signal! Thanks to Wei Chiang for these fixes. * examples/Reactor/Misc/notification.cpp: Added patches to run this example under Chorus. Thanks to Wei Chiang for these fixes. * ace/Connector.cpp (create_AST): Changed the order of some instructions in Connector::create_AST method to make it more safer to use in multi-thread environment. Thank to Paul Han for reporting the problem and the fix. * ace/Connector.cpp (create_AST): Make sure to pass in the "mask" when calling remove_handler() so that we get the right set of bits removed from the Reactor. * tests/Reactor_Timer_Test.cpp (class Time_Handler): Changed int to long to avoid type conversion problems on 64 bit SGI. Thanks to Fred LaBar for reporting this. * examples/Reactor/FIFO: Added a test program to illustrate the interaction of the ACE Reactor with the FIFO IPC mechanism. Thanks to Johannes Gutleber for this test. * examples/Reactor/Misc/pingpong.cpp: Added support for Chorus. Thanks to Wei Chiang for this. * ace: Added a number of minor changes to signal assignment code so that ACE will compile with Tandem NonStop. Thanks to Jan Perman for these fixes. * ace/config-tandem.h: Added a new config file for the Tandem NonStop-UX 4.2MP platform. Thanks to Jan Perman for contributing this. * include/makeinclude/platform_tandem.GNU: Added a new platform file for the Tandem NonStop-UX 4.2MP platform. Thanks to Jan Perman for contributing this. * ace/config-unixware-2.1.2-g++.h: Added a new config file for UNIXWARE 2.1.2. Thanks to Ganesh Pai (gpai@voicetek.com) for contributing this. * include/makeinclude/platform_unixware_g++.GNU: Updated the UNIXWARE platform config file to work for version 2.1.2. Thanks to Ganesh Pai (gpai@voicetek.com) for contributing this. * ace/Handle_Set.cpp (count_bits): Added another 0xff mask to prevent problems with sign extension on machines with 32 bit ints and 64 bit longs. Thanks to James Johnson for reporting this. * ace/OS.h: Updated all of the ACE_DEFAULT* macros in OS.h so that they can be overridden by #defines in the config.h file. Thanks to Chuck Gehr for suggesting this. Thu Jun 19 22:20:20 1997 David L. Levine * ace/OS.h (VxWorks/g++ only): added horrible hack to work around mismatch of memcmp, etc., prototypes in . * ace/OS.i: reordered many function definitions to avoid use before definition. Building with g++ 2.7.2 on VxWorks 5.3.1 revealed them. * ace/config-vxworks5.2-g++.h: removed ACE_HAS_STRING_CLASS and ACE_HAS_GNU_CSTRING_H, because those aren't distributed with Tornado 1.0.1. Thu Jun 19 15:31:53 1997 Darrell Brunsch * ace/Timer_Wheel_T.cpp: Fixed problem with expire () not expiring timers with a timeout of the current time. This was causing problems with Timer_Queue_Test when high profile timers were disabled (such as Windows NT when the environment variable ACE_SCALE_FACTOR was undefined) Wed Jun 18 19:43:35 1997 David L. Levine * ace/Signal.cpp: 'removed "const" from #define of ACE_MAX_SIGNAL_HANDLERS because it broke Irix 6.2 build. Thanks to Gonzalo A. Diethelm for reporting this. * examples/Threads/task_four.cpp (Invoker_Task::svc): fixed typo, n_tasks instead of ntasks. Wed Jun 18 11:25:14 1997 Nanbor Wang * examples/Threads/{task_four,token}.cpp: Changed the use of cerr/cout to ACE_DEBUG macro. Thanks to Chuck Gehr for pointing these out. Tue Jun 17 15:11:09 1997 David L. Levine * ace/config-sunos5.5-sunc++-4.x.h, include/makeinclude/platform_sunos5_sunc++.GNU: support enabling of exception handling via "exceptions=1" make flag. Exception handling does seem to work with Sun C++ 4.2, even on MP machines, if patch 104631-02 "C++ 4.2: Jumbo Patch for C++ 4.2 on Solaris SPARC" is applied. Please beware that enabling of exception handling can adversely affect peformance, even if the program doesn't use it. So, we haven't enabled it by default. Thanks to Chris Cleeland for suggesting not to enable it by default. * ace/IOStream.h: added #include of "ace/config.h" so that ACE_LACKS_ACE_IOSTREAM can be checked. Thanks to Ganesh Pai for reporting this problem. * ace/ACE.cpp (get_handle): use /dev/udp instead of /dev/ip on SVR4 machines because it has other read permission by default (on Solaris 2.x). * ace/ACE.cpp (get_ip_interfaces): use auto_array_ptr instead of auto_ptr so that the array gets deleted properly, and zero it out to avoid unitialized memory read reports from Purify. * ace/Timer_Hash_T.cpp (cancel): added "[]" to delete of timer_ids array. Purify rules. * Timer_Queue_Test.cppc (test_performance): added "[]" to delete of times array. Purify rules. Tue Jun 17 15:31:01 1997 Steve Huston * ace/ACE.cpp: Fixed get_ip_interfaces (and count_interfaces) to work properly on HP-UX (and probably other similar UNIXes). Needed to work with non-IP interfaces present, and fixed to copy the IP address without the fudge factor being applied. Tue Jun 17 14:02:01 1997 Nanbor Wang * ace/{Free_List.h,Free_List.cpp,Timer_Queue_T.h}: Added #include "ace/Synch_T.h" to Free_List.h and removed related inclusion from Free_List.cpp and Timer_Queue_T.h. Thanks to Jack Erickson for reporting this problem. Tue Jun 17 09:41:48 1997 David L. Levine * tests/Enum_Interfaces_Test.cpp: changed name of log file to match the program name, so that the one-button test can easily find it. Tue Jun 17 04:58:38 1997 Nanbor Wang * ace/Timer_Queue_T.h: Added include file "ace/Synch_T.h" to avoid compilation errors in SC 4.1. We didn't notice this because most of us have moved to SC 4.2. Don't know why this didn't cause any problem in SC 4.2. Thanks to Jack Erickson for reporting this bug. Mon Jun 16 22:25:18 1997 Steve Huston * ace/ACE.cpp: Fixed conditional compiles to compile the interface counting code for HP - it reports 0 interfaces, so it needs more debugging still. * include/makeinclude/platform_hpux_aCC.GNU: added -g to link command for building shared library. * tests/Buffer_Stream_Test.cpp: fixes to execute correctly and only fail assertions on real failures. Mon Jun 16 19:05:13 1997 Steve Huston * ace/Free_List.cpp: added #include ace/Synch.h, needed by Free_List.i. Fixes compile errors on HP-UX. Mon Jun 16 10:59:55 1997 Darrell Brunsch * ace/Timer_Wheel_T.cpp: Changed expire () so it doesn't access past the end of an array when it finds nothing to expire. Thanks to Norbert Rapp for catching this. Sun Jun 15 03:44:21 1997 Nanbor Wang * examples/Threads/thread_specific.cpp (worker): Changed the output of diagnostics from using cout to using printf. Also corrected several portability problems. Thanks for Chuck Gehr for pointing these out. * ace/OS.i (thread_mutex_trylock): Corrected the code for NT. Now this function returns 0 if lock is obtained and -1 otherwise. Thanks to Robert V. Head for noticing this. * performance-tests/Synch-Benchmarks/Synch_Tests.{mdp.mak}: Added project workspace and makefile for NT to this directory. * performance-tests/Synch-Benchmarks/svc.conf: * performance-tests/Synch-Benchmarks/{Options,Benchmark}.h: * performance-tests/Synch-Benchmarks/*.cpp: Reworked these files to have them compiled on NT. Sat Jun 14 03:53:13 1997 Nanbor Wang * performance-tests/Synch-Benchmarks/pipe_proc_test.cpp (class Pipe_Proc_Test): Changed the type of pipe_handles[] from int to ACE_HANDLE. * performance-tests/Synch-Benchmarks/sysvsema_test.cpp: When creating the semaphore, explicitly cast the key value to (key_t) since NT couldn't handle the conversion. Fri Jun 13 19:32:03 1997 Steve Huston * ace/ACE.cpp: Fixed count_interfaces to compile on non-SVR4 systems such as HP-UX. Not tested yet. * ace/OS.i: Fixed mis-arranged conditional compile for HP-UX in asctime_r. Fri Jun 13 03:13:51 1997 Nanbor Wang * ace/config-win32-common.h: Added a "pragma comment" directive to direct MSVC to link in mswsock.lib automatically. Thanks to Bill Tang for reminding this. * ace/ace.{mak,mdp}: Removed explicit inclusion of mswsock.lib. Thanks to Bill Tang for reminding this. * examples/OS/Process/Process.{mdp,mak}: For some reasons, I got an "unknown link error, please refer to documentation for appropriate technical supports" when building this example on NT (didn't help much, did it?) Reassigning the linked library solved the problem. * examples/OS/Process/process.cpp: Updated class name ACE_ProcessEX to ACE_Process because ACE_ProcessEX no longer exists. Also, all exec'ed programs' absolute names have been changed and let the environment variable "path" to decide which program(s) to exec. Thu Jun 12 15:48:16 1997 Chris Cleeland * ace/ACE.cpp (get_ip_interfaces): Corrected code in the BSDish section so that it at least compiles on Linux. I haven't tested this AT ALL. * ace/Timer_Queue_T.cpp (calculate_timeout): When this was called with the default argument from handle_events(), max_timeout was passed as zero, which would cause a SEGV when attempts were made to deref it. Added protection to simply return a zero ptr in that case. Thu Jun 12 13:18:03 1997 Steve Huston * ace/OS.{h,i,cpp}: Changes for HP-UX 10 primarily. Threads support for DCE Draft 4 threads (bundled with HP-UX 10). Correct usage of reentrant C library functions for HP-UX. * ace/OS.i: Changed timeout argument to 2nd select function to allow the compiler to pick a conversion operator. As it was, HP compiler would not compile it. * ace/Service_Object.cpp: When deleting the service memory pointed to by a void *, use "operator delete" rather than deleting a void, which is prohibited by the current ANSI C++ draft. * ace/config-hpux-10.x.h: This is now a compiler-independent header file, and is included by config-hpux-10.x-hpc++.h. This file contains all correct settings for HP-UX 10.x, and compiler-specific config files should use this - see config-hpux-10.x-hpc++.h. * ace/config-hpux-10.x-hpc++.h: New config file for either of the HP compilers (HP C++ or HP aC++). It figures it out internally, and uses config-hpux-10.x.h for OS details. * include/makeinclude/rules.lib.GNU: Allow for doing a PRELIB step when building a shared library, and not using .shobj/*.so files. This allows HP aC++ to close all template instantiations for the entire library at once, rather than separately, reducing the size of the resultant library significantly. * include/makeinclude/platform_hpux-aCC.GNU: build libraries with templates instantiated all at once. Compile with flags for using the reentrant versions of C library functions. Wed Jun 11 15:20:15 1997 Nanbor Wang * ace/Timer_Queue_T.{h,cpp} (calculate_timeout): Changed the second parameter the_timeout from a ref. to a ptr. to a ptr in order to avoid compilation warning. Since the pointer itself is not modified within the function, it's ok to change this. * ace/Reactor.cpp (wait_for_multiple_events): Added ACE_Time_Value the_timeout as a place holder for timeout value when max_wait_time is NULL. Otherwise, Timer_Queue::calculate_timeout won't process the timer queue even it's not empty. Wed Jun 11 11:14:29 1997 James C Hu * include/makeinclude/platform_mvs.GNU (RANLIB): Requested change from Check Gehr (gehr@sweng.stortek.com), RANLIB = echo Wed Jun 11 04:47:52 1997 Nanbor Wang * ACE.cpp (count_interfaces): Two bugs were corrected here. Both were typo. * tests/Timer_Queue_Test.cpp: Added include file ace/Timer_Queue.h Tue Jun 10 16:02:52 1997 Darrell Brunsch * ace/SString.{h,cpp}: Changed the parameters in CString::substring() and WString::substring(). Removed const and changed length to a ssize_t because of signed/unsigned comparison warnings. * ace/ACE.cpp: Changed a loop variable in get_ip_interfaces() to a size_t because of a signed/unsigned comparison warning. Tue Jun 10 12:47:49 1997 * ace/SString.cpp (operator = and operator +=): There were two bugs here. operator= forgot to tack on the NULL terminator after the memcpy() and operator+= appended the second string incorrectly. Thanks to Michael R. MacFaden for pointing these out. Tue Jun 10 12:16:04 1997 Darrell Brunsch * ace/Makefile: Updated to reflect newly added files * ace/Proactor.cpp: Removed template specializations. * ace/Reactor.cpp: Removed some template specializations. * ace/Timer_Hash.h: Added an include for Timer_Heap. * ace/Timer_Hash_T.cpp: Changed a reference to ACE_Timer_Node to ACE_Timer_Node_T * ace/Timer_{Hash,Heap,List,Wheel}_T.h: Changed #include "ace/Timer_{...}.h" to "ace/Timer_{...}_T.h". * ace/Timer_Queue.cpp: Removed some template specializations. * ace/Timer_Queue.h: Removed the including of Timer_Queue.cpp since there are no templates to warrant it. * ace/Timer_{Hash,Heap,List,Wheel}.cpp: Added these and put the appropriate template specializations here. Tue Jun 10 02:08:25 1997 Nanbor Wang * examples/Log_Msg/README: Revised. * examples/Log_Msg/test_log_msg.cpp: Revised program output so that it's clearer to explain. Mon Jun 09 15:46:41 1997 * OS.i (mutex_lock): When WaitForSingleObject returns WAIT_ABANDONED, the lock is held by the calling thread. Therefore we must return 0 from the method. I have added a new mutex_lock() method that takes an extra "abandoned" parameter. This is set wehen the mutex is abandoned. Thanks to Dieter Quehl for pointing this out. Mon Jun 9 02:31:36 1997 Nanbor Wang * tests/Sigset_Ops_Test.cpp (main): Comment out testing of invalid sigset checking for most platforms don't seem to support it. Perhaps the ACE's sigset* functions should remove this check for compatibility. Sun Jun 8 11:39:06 1997 Douglas C. Schmidt * ace/OS.i (set): There was a typo here where ((long) (d - (double) l)) * 1000000 should be (long) ((d - (double) l) * 1000000) since otherwise the values are always 0. Thanks to Jim Crossley for reporting this. * tests/Enum_Interfaces_Test.cpp (main): Changed ACE_UINT32 to size_t to be consistent with the class definition. Thanks to Nanbor Wang for reporting this. * ace/Token.h: Added some no-op method for ACE_Token so that it will still compile even if ACE_HAS_THREADS isn't defined. Sun Jun 8 01:37:52 1997 Nanbor Wang * examples/Log_Msg/README: Added a README file. * tests/Sigset_Ops_Test.cpp (main): bug fixed. Sat Jun 7 16:40:22 1997 Douglas C. Schmidt * ace/SString.h (string.): Added a substring() member function to ACE_*String classes. Thanks to Michael MacFaden for contributing this. * ace/ACE: Added a new method called int get_ip_interfaces(count, address_array) which will query the OS kernel for the IP addresses for each network interface found and return a count and array of ACE_INET_Addr objects. The reason for adding this method is that most client apps assume gethostbyname(uname|gethostname)) will work. If the nameservices is misconfigured/broken or the machine is multi-homed, the client apps have alot of coding to do to figure out if an inteface represents a local address or not. On UNIX, this includes the loopback addr. On NT, the loopback addr is not added (but may change the impl if others think this useful). Thanks to Michael MacFaden for contributing this. * ace/Synch[_T]: Changed all the classes so that internal instance variables are now protected rather than private. This allows greater flexibility if there's a need to subclass (which shouldn't occur very much...). Thanks to Reza Roodsari for suggesting this. Fri Jun 06 21:30:57 1997 David L. Levine * ace/Timer_{Hash,Wheel}_T.cpp: added #includes of ace/High_Res_Timer.h. Also, in Timer_Wheel_T.cpp (cancel), moved the declaration of "i" out of the loop because it's used in two different loops. Fri Jun 06 17:11:13 1997 * OS.i (sleep): If ACE_POLL_IS_BROKEN is defined, use select() to do micro second sleeps. * ace/CORBA_Handler.h (ACE_CORBA_*): The new version of Orbix (2.2C01) on NT finally supports namespaces. So now the macros ACE_CORBA_n need to be defined using the "::" and not the "_" for NT if the new Orbix is being used. Thanks to John Morey (jmorey@tbi.com) for the changes. Fri Jun 06 02:16:08 1997 * Sigset_Ops_Test.cpp: Added to test correct implementation of sigset manipulating functions. * run_tests.{sh,bat}, Makefile: Added Sigset_Ops_Test. Thu Jun 05 20:32:39 1997 David L. Levine * tests/Timer_Queue_Test.cpp (randomize_array): removed static qualifier now that it's a template function. It caused a warning with Sun C++. Thu Jun 05 18:28:36 1997 * ace/Asynch_Acceptor.cpp (open): The Proactor was beening passed implicitly. I have made this explicit by making this a parameter to open. Thanks to MehulM@spa-marketing.com (Mehul Mahimtura) for this. Thu Jun 5 12:06:45 1997 Chris Cleeland * ace/Timer_Queue_T.h (ACE_Timer_Queue_T): Overloaded calculate_timeout with a version that accepts a pointer to storage for the ACE_Time_Value as an argument. This has a small performance win over the other b/c it does not take a lock. The change was made after examining Quantify output for TAO and observing that this lock caused Reactor::wait_for_multiple_events() to consume a substantial percentage of processing time. * ace/Reactor.cpp (wait_for_multiple_events): This now uses a different version of calculate_timeout() that doesn't require taking a lock. Thu Jun 05 08:48:49 1997 David L. Levine * ace/Reactor.cpp: added template specializations. * ace/Timer_Queue_T.cpp (ACE_Timer_Queue_T ctor): rearranged initializers to match declaration order. Thu Jun 5 06:08:06 1997 Nanbor Wang * ace/OS.i (sigaddset, sigdelset, sigismember): NSIG itself is invalid and must be excluded. Wed Jun 04 21:24:35 1997 David L. Levine * ace/config-sunos5.5-g++.h: fixed typo: #define instead of #defined ACE_HAS_CLOCK_GETTIME. * ace/config-sunos5.5-sunc++*.h: Combined config-sunos5.5-sunc++-4.x.h and config-sunos5.5-sunc++-4.1.h, and removed the latter. The Orbix config file now #includes config-sunos5.5-sunc++-4.x.h and adds its differences. * include/makeinclude/platform_sunos5_sunc++*.GNU: Combined platform_sunos5_sunc++.GNU and platform_sunos5_sunc++-4.1.GNU, and removed the latter. platform_sunos5_sunc++_orbix.GNU now includes the non-orbix file and adds its differences. Also, added optional CC -fast support. To enable, just add "fast=1" to your "make" invocation. Wed Jun 04 12:21:41 1997 * tests: Made the following config files consistent: UNIXclerk.conf UNIXtokens.conf Win32clerk.conf Win32server.conf Win32tokens.conf * ace/OS.h: Made sure that some #defines were guarded for redefinition specially for the Bristol (that provides Win32 API on AIX) headers. Thanks to Rich Christy (rchristy@cccis.com) for suggesting these changes. * ace/Handle_Set.h: Changed the type of handle_index from int to u_int on Win32. Thanks to Jack Erickson (jack@cibc.com) for suggesting this. * ace/FILE.h (ACE_FILE_STREAM): Fixed this #define from ACE_FILE_Stream to ACE_FILE_IO. Tue Jun 3 21:23:48 1997 Douglas C. Schmidt * ace/Timer_{Queue,Hash}: Fixed some uses of template typedefs since GCC is too lame to handle them correctly. Therefore, I had to expand TIMER_QUEUE into the ugly fully expanded name. * ace/Timer_Queue_T.cpp: Moved the implementation of ACE_Event_Handler_Handle_Timeout_Upcall from Timer_Queue.* into Timer_Queue_T.* since only template classes should go into *_T.* files. Tue Jun 3 18:16:02 1997 Darrell Brunsch * ace/Timer_Queue.*: Templatized ACE_Event_Handler_Handle_Timeout_Upcall with LOCK Added deletion() to Upcall Functors. This gets called if there are any nodes in a queue and the queue's destructor is called * ace/Timer_Queue_T.*: Changed iterator accessor to public Removed two template parameters from ACE_Timer_Node_T so only EVENT is left. Added accessors instead of using friendships, and deleted the constructor (use set() instead) Changed iterator into a general iterator (with first(), next(), isdone() and item () methods) Added remove_first () method that removes and returns the earliest timer in the queue Added ACE_Free_List support * ace/Timer_Heap*: Added upcall functor deletion() support Added remove_first () method that removes and returns the earliest timer in the queue * ace/Timer_List*: Changed to double-linked circular list and changed the timer_id to be a pointer to the node (like it is in Timer Wheel and Timer Hash) Added upcall functor deletion() support Added remove_first () method that removes and returns the earliest timer in the queue Added check for timer_id of -1 so we don't try to delete the error code if it is passed into cancel Changed Timer_List_Iterator_T constructor parameter from list to listParm to resolve a conflict with STL. Thanks to Todd Barkalow for this fix * ace/Timer_Wheel*: Added HighRes timer support Added upcall functor deletion() support Added earliest_pos_ variable to keep track of the list with the earliest node Created an expire that is specialized for ACE_Timer_Wheel Added remove_first () method that removes and returns the earliest timer in the queue Added check for timer_id of -1 so we don't try to delete the error code if it is passed into cancel * ace/Timer_Hash*: Added Timer Hash Queue - This is a class that can take another timer queue type (Timer List, Timer Heap...) as a template parameter (BUCKET) and then do an intermediate hash of a timer to determine which queue among a table of timer queues to put the timer into. ACE_Timer_Hash is typedefed to the Timer List version and ACE_Timer_Hash_Heap is typedefed to the Timer Heap version Added HighRes timer support Added upcall functor deletion() support Created an expire that is specialized for ACE_Timer_Hash Added remove_first () method that removes and returns the earliest timer in the queue Added check for timer_id of -1 so we don't try to delete the error code if it is passed into cancel * ace/Free_List.* Added ACE_Free_List and ACE_Locked_Free_List. These are used to maintain free lists of nodes. ACE_Free_List is a abstract class where ACE_Locked_Free_List is a concrete one that has a mutex parameter (LOCK). * ace/OS.h: Added ACE_DEFAULT_TIMER_HASH_TABLE_SIZE constant Added ACE_DEFAULT_FREE_LIST_* constants * ace/Proactor.*: Added deletion() to Upcall Functors. This gets called if there are any nodes in a queue and the queue's destructor is called. * tests/Timer_Queue_Test.cpp: Added HighRes timer support Changed the array of timer queues into a list (to more easily add/remove/comment out an entry) Added some more performance tests with randomization Tue Jun 3 00:26:06 1997 Douglas C. Schmidt * ace/OS.h: Changed the access protection for ACE_cond_t, ACE_sema_t, ACE_event_t, and ACE_rwlock_t so that it is protected rather than private. In addition, added ACE_Export to all of these classes so that they are visible outside of a DLL. Thanks to Ivan Murphy for these suggestions. * ace/OS.h: Changed the value of ACE_MAX_DEFAULT_PORT on Win32 to 0 in order to work around a nasty NTism... Thanks to Jon Biggar for reporting this. Mon Jun 2 16:29:48 1997 James C Hu * ace/Process.*: - Fixed ACE_Process::spawn to close descriptors after having been duped. - Fixed ACE_Process::spawn to exit () after an error is encountered in the child process, rather than returning. - Fixed ACE_Process_Options::set_handles to duplicate handles that are passed in, and then to close them in the destructor. Sun Jun 01 22:21:28 1997 David L. Levine * examples/Threads/tss1.cpp: made some globals non-static or const so that tss1 will link with Sun C++ 4.2 -O3. I don't know what the problem is; it only shows up with optimization enabled. These fixes work around it. Sun Jun 01 20:29:20 1997 James CE Johnson * ace/IOStream*: - removed the old 4/5/97 comments - made operator>>, << on QuotedString a template This last makes QuotedString much more functional. As templated functions, the QuotedString can now be used on other iostream-type objects. The previous method of defining the function only for the type of ACE_IOStream being created was didn't provide this flexibility. Sat May 31 07:01:22 1997 Douglas C. Schmidt * ace/Log_Msg.cpp (open): To avoid handle leaks, we need to shutdown the message_queue before trying to reopen it. Thanks to Per Andersson for this suggestion. * include/makeinclude/platform_osf1_4.0.GNU: Added a new platform config file. Thanks to James Johnson for this. Fri May 30 16:25:25 1997 * CPP-inclient.cpp (main): Properly compare to the "quit" string. Thanks to "Andre Arpin" for reporting this. * tests/UPIPE_SAP_Test.cpp (connector): Changed the eof marker in the strings. Fri May 30 14:04:44 1997 James C Hu * include/makeinclude/platform_irix6.4_sgic++.GNU: added to make things compile on latest SGI machines. Removed +pp and -woff... flags from the CCFLAGS variable. Added new -woff flags to hide other warnings. * ace/config-irix6.4-sgic++*.h: copied corresponding configs from irix6.2 and removed ACE_HAS_SVR4_TIME, since this seems to be no longer true of irix6.4. Fri May 30 02:39:39 1997 * ace/Connector.cpp (create_AST): On Win32, added the except mask when registering with the Reactor to find out when asynchronous connects complete. (Svc_Tuple): Made sure that the default value for the timer_id in AST is not 0. 0 is a valid timer_id. I have changed this to be -1. (handle_exception): Added this method. On Win32, the except mask must also be set for asynchronous connects. Thu May 29 21:28:25 1997 * Process.*: Removed the ACE_Process_Old class. * Local_Tokens_T.*: Removed all these files. They have not been used by the token library for some time. They were mistakenly put in the release. Thu May 29 02:00:14 1997 * ACE.cpp (is_process_active): Added this method which checks if a process is still alive. Thanks to Chris (CLahey@cccis.com) for this code. * ace/OS.i (kill): Changed PROCESS_ALL_ACCESS to PROCESS_TERMINATE. * ace/ACE.cpp (bind_port): Changed the implementation of this method such that a recently used port is not used again in the next call to this method on Win32, i.e., upper limit is decreased even in the successful case. This fixes the problem on Win32 where binding to a recently used port works but the following connect fails. * ace/Acceptor.cpp (close): Added a close method that allows us to shutdown the Acceptor (without having to destroy it). * ace/Connector.cpp (close): Added a close method that allows us to shutdown the Connector (without having to destroy it). * apps/Gateway/Gateway/Proxy_Handler_Connector.cpp (handle_close): Removed this method. This code seemed to be duplicating the code in the handle_close of the proxies. (initiate_connection): Removed the code that did rescheduling. The proxies are responsible for this. * apps/Gateway/Gateway/Event_Channel.cpp (initiate_proxy_connection): Must *always* use the correct synch options while connecting. (reinitiate_proxy_connection): Always register for timeouts if we are not disconnecting. This allows us to remove duplicated logic in Proxy_Handler_Connector. The new logic of close() allows us to remove the code that use to remove the proxy from the map to prevent double deletes. (close): Changed the shutdown logic to: Tell everyone that the spaceship is here (behind the comet), close down the connector, close down the acceptor, tell everyone that it is now time to commit suicide. * apps/Gateway/Gateway/Proxy_Handler.cpp (handle_timeout): Must return 0, or else the timer queue will cancel the handler and *all* its timeouts. * apps/Gateway/Peer/svc.conf,Makefile: We now generate a Peer shared library (instead of just an .so). The svc.conf was changed to reflect this. * tests/UPIPE_SAP_Test.cpp: Fixed output message. * Handle_Set.i (operator): Fixed typo. Thu May 29 11:09:52 1997 David L. Levine * include/makeinclude/rules.local.GNU: check for directory write permission before attempting to install. This helps support shared ACE workspaces. There are two easy ways to not install "private" libraries in the shared workspace: 1) remove write permission from $WRAPPER_ROOT/ace, or 2) add "INSTALL=" to invocations of "make". Thu May 29 06:07:18 1997 Douglas C. Schmidt * ace/OS.i (thr_join): Revised some code in the #ifdef'd out version of ACE_OS::thr_join() so that it will compile correctly. Note that this code isn't currently used, but someday it will be. Thanks to Hamutal Yanay for reporting this. Wed May 28 16:37:57 1997 David L. Levine * ace/OS.{h,i} (ACE_Time_Value): added default constructor, which does not call normalize (). ACE_Time_Value::normalize () was showing up as a relatively minor, but signficant hot spot in Event Channel latency tests. Wed May 28 16:02:53 1997 James C Hu * ace/OS.i: Changes to strdup and getpid for CHORUS, as per Wei Chiang's suggestions. Tue May 27 18:26:51 1997 Douglas C. Schmidt * ace/config-hpux-10.x-decthreads.h: Added support for HP/UX 10.10 with DCE threads. Thanks to Shankar Krishnamoorthy for these fixes. * ace/Local_Tokens_T.h: #if def'd out all of this file since it doesn't seem to be used anymore. Thanks to Shankar Krishnamoorthy for reporting this. * ace/Makefile (TEMPLATE_FILES): Removed Local_Tokens_T since it doesn't appear to be used anywhere. Tue May 27 18:47:34 1997 James C Hu * tests/*.cpp: Various changes for EBCIDIC compatibility. Thanks to Chuck Gehr for pointing out the need for this! * tests/test_config.h: Added ACE_ALPHABET to aid a-z sending and comparing. Tue May 27 15:03:25 1997 David L. Levine * tests/Future_Test.cpp: added ACE_Future{_Rep} template specializations. Tue May 27 07:49:03 1997 Douglas C. Schmidt * ace/Future.cpp: Made a few minor reformatting changes to Per's new Future enhancements. Tue May 27 14:19:14 1997 Per Andersson * ace/Future: Fixed self assignment bug in ACE_Future<>::operator=(). Fixed bug in ACE_Future<>::set(). It is now possible to do a ACE_Future<>::set() followed by a ACE_Future<>::get() without hanging forever. Moved all handling of the ACE_Future_Rep<> reference count into three new static ACE_Future_Rep<> member functions, create, attach, assign and detach. Removed one mutex from ACE_Future_Rep<> by changing the reference count from an ACE_Atomic_Op into a plain int. The ACE_Future_Rep<>::value_ready_mutex_ mutex is instead used for serializing changes to the reference count. (ACE_Future_Rep<>::attach, ACE_Future_Rep<>::detach()) Removed mutex from ACE_Future<> the serialization is performed by the ACE_Future_Rep<>::attach, ACE_Future_Rep<>::detach() and ACE_Future_Rep<>::assign() functions. Changed the ACE_Future<> default constructor to always create a ACE_Future_Rep<> * tests/Future_Test.cpp: Added test case for ACE_Future<>::set() followed by ACE_Future<>::get(). Added test for working ACE_Future::operator=(). The test is not fool proof but it crashes or hangs the test process with the old ACE_Future<> implementation. Mon May 26 14:19:14 1997 James C Hu * ace/OS.{h,i}: Fixed difftime implementation for cases where systems implement it as a macro. Fixed tempnam by adding ACE_LACKS_TEMPNAM. Sun May 25 11:36:22 1997 Douglas C. Schmidt * examples/Reactor/Misc: Removed test_handle_set.cpp since it is now completed subsumed by tests/Handle_Set_Test.cpp. * tests/Handle_Set_Test.cpp: Updated the test of the ACE_Handle_Set so that it shows how fast the iterator works. * ace/Reactor.cpp: Updated the Reactor to use the new ACE_Handle_Set_Iterator (whic no longer requires calling operator++ to advance the iterator). * ace/Handle_Set: Rewrote the ACE_Handle_Set_Iterator to speed it up. The result seems to be about 15% faster than the original. * ace/OS.h: Changed the MSB_MASK static constant into a macro and moved it from Handle_Set.cpp into OS.h, changing its name to ACE_MSB_MASK. * ace/Sched_Params.cpp (priority_max): Added another #ifdef for Chorus. Thanks to Wei Chiang for reporting this. * include/makeinclude/platform_sunos5_sunc++_orbix.GNU: added -l in front of orbixmt. Thanks to Wei Chiang for pointing this out. * ace/ACE.cpp: Changed the default port for NT so that it starts at 65279 rather than 65535. Hopefully, this will fix that annoying bug that has been plaguing us on NT 4.0 for months. Thanks to Goran Lowkrantz for reporting this. Sat May 24 23:42:32 1997 David L. Levine * performance-tests/Misc/test_naming.cpp (do_testing): replaced strlen () calls in character array size with constant expression. Sat May 24 12:07:48 1997 Douglas C. Schmidt * Released version 4.2.1 for testing. * ace/Reactor.cpp (bind): Fixed a stupid typo where I was using the ACE_REACTOR_EVENT_HANDLER macro instead of the ACE_REACTOR_HANDLE macro. Thanks to Detlef for reporting this. * ace/OS.i: Added a new macro called ACE_HAS_THR_MINSTACK to deal with weirdo mangling of names by Tandem. Thanks to Jan Perman for reporting this. * ace/OS.h: Added a new macro ACE_LACKS_PRI_T for those platforms using STHREADS (e.g., Tandem NonStop OS) that don't have pri_t defined. Thanks to Jan Perman for reporting this. * ace/Connector.cpp (connect): Make sure to save/restore errno since svc_handler->close() may change it. Thanks to Michael Hartman for reporting this. * include/makeinclude/platform_chorus.GNU: Added a new platform macros file for Chorus. Thanks to Wei Chang for this. * ace/OS.cpp (sched_params): Reordered the #ifdefs so that Chorus comes first. * ace/OS.i (sleep): If the platform defines ACE_HAS_CLOCK_GETTIME then we'll use the nanosleep() method rather than sleep(). * ace/OS.h: disabled THR_NEW_LWP for Chorus. Thanks to Wei Chang for reporting this. * ace/Sched_Params.cpp: ACE_SCHED_OTHER and ACE_SCHED_RR have the same value on Chorus. Thanks to Wei Chang for reporting this. Sat May 24 09:21:08 1997 David L. Levine * netsvcs/lib/Server_Logging_Handler.cpp: protected second ACE_Svc_Handler specialization for case that ACE_HAS_THREADS, when ACE_HAS_TLI. It had gotten lost in the last pass of that module. Thanks to Sandro Doro for reporting this problem. Sat May 24 03:19:38 1997 Nanbor Wang * ace/OS.i (sigaddset, sigdelset, sigemptyset, sigfillset, sigismember): Modified the implementation of these function so as to conform with POSIX standard. Basically all functions do the same things they did but more conservative protections are added. The modified semantic becomes, sigemptyset, sigfillset, sigaddset, sigdelset: return 0 if succeed, -1 otherwise. sigismember: returns 0 if signum is not in the set, 1 if signum is in the set, and -1 if error occurs. If error occured, errno will be set to one of the following value: EFAULT: sigset is not a valid address. EINVAL: signum is not a valid signal number. Notice that, so far, this is for NT only. Sat May 24 01:53:22 1997 James C Hu * performance-tests/Misc/test_naming.cpp (do_testing): Thanks to Sandro Doro, squashed a bug where we were trying to concatenate onto a string constant. Fri May 23 01:01:01 1997 Douglas C. Schmidt * ace/config-hpux-9.x.h: Added #define ACE_HAS_BROKEN_ENUMS #define ACE_HAS_IP_MULTICAST #define ACE_LACKS_GETPGID Thanks to Neil Cohen for reporting these. * ace/Thread_Manager.h: Made the private methods and data members protected so that subclasses can extend it. Thanks to Hamutal Yanay for this suggestion. Fri May 23 21:27:05 1997 David L. Levine * ace/Process.{h,cpp} (env_argv): added "const" to char * type in return type, for argument compatibility in call to ACE_OS::execve (). * ace/Process.cpp (spawn): removed unreachable return statement at end of function. Thanks to Dave Mayerhoefer for reporting the above two problems. * ace/{IOStream*,Makefile}: Split out templates into ace/IOStream_T.{h,cpp} files. This way, automatic template instantiation systems that require templates to be in separate files, such as on Irix 6.2, will be able to build IOStream_Test and the ACE_IOStream examples without warnings. (The ACE_IOSTREAM_BUILDING_TEMPLATE macro that did this only worked if ACE_TEMPLATES_REQUIRE_SOURCE was defined. It's no longer needed with the separate template files.) * tests/IOStream_Test.cpp, examples/IOStream/client/iostream_client.cpp, examples/IOStream/server/iostream_server.cpp: swapped ACE_Streambuf and ACE_Streambuf_T class names so that the template class has the "_T". And renamed ACE_IOStream_T for consistency. * ace/{IOStream.*,README}, tests/IOStream_Test.cpp, examples/IOStream/client/iostream_client.cpp, examples/IOStream/server/iostream_server.cpp, config-hpux-9.x*.h: Added ACE_LACKS_ACE_IOSTREAM protection so that these can easily be built on platforms that have trouble with ACE_IOStream. * Priority_Task_Test.cpp: removed close () because it didn't really close the Task, and added printout to main () after all tasks have been spawned to help debug non-termination. * ace/OS.cpp: (thr_create, with STHREADS only): *thr_handle was used but *thr_id had been set by ::thr_create, so threads never got activated. Fixed by using *thr_id instead of *thr_handle in the calls to ACE_OS::thr_setprio and ACE_OS::continue. Thanks to Jan Perman for reporting this problem. Fri May 23 20:12:33 1997 James C Hu * tests/SV_Shared_Memory_Test.cpp: Thanks to Chuck Gehr, fixed ASCII dependent code in the parent and child routines. Fri May 23 02:58:28 1997 Nanbor Wang * ace/OS.i (dlsym): Added ACE_USES_ASM_SYMBOL_IN_DLSYM, support for platforms (FreeBSD) which use assembly symbols instead of C symbols in dlsym (). * ace/config-freebsd[-pthread].h: Added flag ACE_HAS_CHARPTR_DL and ACE_USES_ASM_SYMBOL_IN_DLSYM. Thu May 22 08:14:21 1997 David L. Levine * tests/Tokens_Test.cpp: added deletes to avoid memory leaks. Wed May 21 16:15:48 1997 David L. Levine * ace/{config-irix6.2*.h,README}: removed ACE_LACKS_IOSTREAM_SETGET because tests won't build with it. Also, added ACE_LACKS_SIGNED_CHAR. * ace/IOStream.h: removed "const" from PUT_PROT of u_char * and void *. This should allow the IOStream test and examples to build and run on Irix platforms. Thanks to Torbjorn Lindgren and Amos Shapira for reporting this, and to James Hu for helping fix it. * ace/{OS.cpp,Sched_Params.cp} (Solaris only): use 0 min priority again, with workaround in ACE_OS::thr_create to not use ::pthread_attr_setschedparam () if the priority is 0. Instead, the priority of the newly created thread is set to 0 (if it wasn't created with 0) after the thread is created, with ::pthread_setschedparam (). Wed May 21 15:23:37 1997 Chris Cleeland * ace/Strategies_T.* (ACE_Hash_Addr): Eliminated the ADDR_T template parameter as a base class. It is now a wholly-contained member of the ACE_Hash_Addr<> with conversion operators. This caused problems on certain compilers, notably HP-UX. Wed May 21 14:13:36 1997 James C Hu * ace/OS.{h,i} (difftime): Added implementation to ACE_OS. I don't expect any problems since it is in ANSI. * ace/OS.{h,i} (tempnam): Added implementation to ACE_OS. Wed May 21 01:17:40 1997 Douglas C. Schmidt * Released version 4.2. * ace/Acceptor.cpp (activate_svc_handler ): Removed an unnecessary return 0. Thanks to Amos Shapira for reporting this. * ace/Message_Block.cpp (release): I believe that ACE_Message_Block::release() should return something other than 0, i.e., it should return the result of release_i(). Thanks to Amos Shapira for reporting this. Wed May 21 01:17:40 1997 Per Andersson * Moved most code from netsvcs/lib/Server_Logging_Handler.* to Server_Logging_Handler_T.*. Made template out of ACE_Server_Logging_Handler and ACE_Server_Logging_Acceptor. Factorised out as much as possible to reduce code duplication. The log record processing was moved from ACE_Server_Logging_Handler it should now be handled by the Log_Message_Receiver class. It is now possible to change how log records processed without changing code in Server_Logging_Handler* and it is possible to have several Server_Logging_Handlers that processes log records in different ways without duplicating all the server code. All that is needed is to write a new/change Log_Message_Receiver and instantiate a couple of templates. * netsvcs/lib/Server_Logging_Handler.h added lots of typedefs for making template instantiations easier. * netsvcs/lib/Server_Logging_Handler.h addad lots template instatiations, there are now 58 all together. * Added netsvc/lib/Log_Message_Receiver.{h,cpp}, implementstwo simple log message receivers that prints the log record to stderr. Tue May 20 13:50:17 1997 Douglas C. Schmidt * ace/config-hpux-9.x.h: Added a #define for ACE_HAS_BROKEN_ENUM, ACE_HAS_IP_MULTICAST, and ACE_LACKS_GETPGID. Thanks to Neil Cohen for reporting this. * include/makeinclude/platform_sunos5_sunc++_orbix.GNU: Replaced the use of -lITsrv with -lorbixmt. Thanks to Wei Chiang for this. * include/makeinclude/platform_osf1_3.2.GNU: Make sure that all the template repositories are in the same directory to work around problems with the C++ compiler. Also added -lrt to get the apps and tests to run. Thanks to Tom Dobridge for this help. Tue May 20 17:13:15 1997 Carlos O'Ryan * ace/config-hpux-10.x-nothread.h: * ace/config-hpux-10.x-aCC.h: * ace/Stream_Modules.cpp: ACE_LACKS_STREAM_MODULES is no longer needed, moving the inclusion of "ace/Task.h" to the beginning of "ace/Stream_Modules.h" solved the problem nicely. * ace/config-hpux-10.x.h: * ace/config-hpux-10.x-aCC.h: ACE_HAS_BROKEN_HPUX_TEMPLATES is not needed on newer HP/CXX compilers; further, old ones will not compile ACE even if the macro is defined. * ace/Timer_List_T.h: * ace/Timer_Queue_T.i: I moved the definition of ACE_Timer_Queue_T::lock() from the .i file to the .h file, HP/CXX gets completely confused otherwise. I also added a number of ACE_INLINE missing in the .i file. * ace/Stream_Modules.h: * ace/Stream_Modules.cpp: I had to move the inclusion of "ace/Task.h" outside of the protections against multiple inclusion for Stream_Modules.h. That seems to solve the ciclyc dependancy for Task->Module->Stream_Module->Task. BTW, the same thing was already done in "ace/Log_Record.h". I'll try to remove the ACE_LACKS_STREAM_MODULES macro, it seems that the last change makes it redundant. * ace/Signal.cpp: HP/CXX compiler will not close the library unless ACE_MAX_SIGNAL_HANDLERS is defined as "const size_t". The previous definition ("size_t") did compile tough. * ace/Log_Record.h: We need to include "ace/ACE.h" before "ace/Log_Priority.h". * ace/Log_Priority.h: HP/CXX compiler seems to reserve a few bits in enums, so the ENSURE_32_BITS trick would result in a compile time error. Since HP enums are always 32 bits we could skip the definition for ENSURE_32_BITS altogether, but I prefer to keep a consistent namespace across plaforms, I have found a value for ENSURE_32_BITS that seems to work. * include/makeinclude/platform_hpux.GNU: Some options to improve compile time, since we use explicit template instantiation there is no need for a ptcomp o ptlink phase. Tue May 20 09:10:18 1997 Nanbor Wang * ace/config-freebsd-pthread.h: * ace/config-freebsd.h: Removed "FreeBSD" directive because gcc on FreeBSD defines __FreeBSD__ automatically. * ace/OS.i (sigaddset, sigdelset, sigismember): Added range checking to these functions in order to avoid disasters. Sig number should be between 1 and NSIG. (sigwait): Changed ifdef (FreeBSD) to ifdef (__FreeBSD__) since compiler does it for us. Tue May 20 08:41:11 1997 David L. Levine * examples/Threads/tss2.cpp: added #include of ace/Thread.h because Sun C++ 4.1 needs it. Mon May 19 16:04:32 1997 David L. Levine * bin/create_ace_build: changed startup line for compatibility with bash. This startup line lets the script run without hard-coding the full path to the perl executable, as long as perl is on the user's PATH. Mon May 19 12:45:21 1997 Douglas C. Schmidt * examples/Threads/reader_writer.cpp: Changed the code so that we don't try to treat thread ids as ints! Thanks to Chuck Gehr for reporting this. Sun May 18 21:57:54 1997 David L. Levine * examples/Threads/tss2.cpp: added second parameter to ACE_TSS_Singleton template specialization. Sun May 18 09:20:15 1997 Douglas C. Schmidt * examples/Threads/TSS_Data.h: Added the second parameter for ACE_SYNCH_MUTEX since Rich and Chris updated ACE_TSS_Singleton. * ace/Singleton.cpp: Added the updated version of ACE_TSS_Singleton that implements the Double-Checked Locking pattern. Thanks to Rich Christy and Chris Lahey for this. * ace/Strategies_T.cpp (activate_svc_handler): Fixed the logic so that a value is always returned. Thanks to David Levine for noticing this. Sun May 18 07:25:11 1997 David L. Levine * netsvcs/lib/Server_Logging_Handler.cpp: removed second ACE_Svc_Handler specialization for non-threaded, has-TLI case. That's because it is the same as the first; the only difference was that one specialized with ACE_SYNCH and the other with ACE_NULL_SYNCH. Without threads, those macros expand to the same thing. Thanks Sandro Doro for reporting this. * examples/Threads/tss2.cpp: added ACE_TSS template specialization. Sat May 17 23:24:34 1997 Nanbor Wang * ace/OS.i (sigismember): Corrected the code when ACE_LACKS_SIGSET. Sat May 17 00:06:04 1997 * examples/ASX/Event_Server/Transceiver/transceiver.cpp (Event_Transceiver): Corrected signal registration for Win32. * apps/Gateway/Gateway/Gateway.cpp (parse_args): Since the Connector is now fixed, non-blocking is now working fine. * ace/Connector.cpp (handle_close,create_AST): Made sure we close down the svc_handler on error. * ace/{Acceptor.cpp,Connector.cpp} (activate_svc_handler): The if statement logic in these methods was incorrect. * ace/SOCK_Connector.cpp (connect): Just like in complete(), we start out with non-blocking disabled on the . * ace/OS.h: When ACE_LACKS_SIGSET is defined, changed the definition of sigset_t from void * to unsigned int. Sat May 17 12:25:22 1997 Douglas C. Schmidt * ace/{Acceptor,Connector,Strategies_T}: Make sure to either enable or disable ACE_NONBLOCK (depending on the flags). This ensures that we always start with the I/O mode set to a deterministic state. Thanks to Irfan for suggesting this. * ace/Connector: Added a new "flags" parameter to the ACE_Connector and ACE_Strategy_Connector which keeps track of flags that control how Svc_Handler are initialized prior to being activated. * ace/Strategies_T.cpp (activate_svc_handler): Make sure to set the peer's handle into non-blocking mode *before* calling the Svc_Handler's open() method. This ensures that things are set up correctly when this hook is called. Sat May 17 02:19:27 1997 Nanbor Wang * ace/config-freebsd.h (ACE_HAS_BROKEN_TIMESPEC_MEMBERS): * ace/OS.i (set, timestruct_t, nanosleep): * ace/High_Res_Timer.cpp (elapsed_time): * ace/README: Added ACE_HAS_BROKEN_TIMESPEC_MEMBERS so that we can fix that problem FreeBSD 2.1.x brings by defining timespec as { time_t ts_sec ; long ts_nsec }. Notice: This is highly non-portable. Please refer to ACE code and see how to write portable. Fortunately, only older versions of FreeBSD have this. Yesterday's hack didn't work, so, it's removed. Thanks to Satoshi Ueno for reporting and helping debug on his FreeBSD 2.1.7R box. Sat May 17 00:06:04 1997 * apps/Gateway/Gateway/Proxy_Handler.cpp (open): Turn on non-blocking I/O only after the Channel is done sending the id to the Peer. * apps/Gateway/Gateway/Gateway.cpp: - Added necessary DLL build macros. - Removed error checking for Reactor::remove_handler() for STDIN as STDIN is never registered with the Reactor on Win32. - Fixed the registration of SIGINT. - blocking_semantics_ should be 1 when blocking is on and not 0. - Since the Connector is currently broken with respect to non-blocking connects, I have put a temporary fix such that only blocking connects are done. Revert this after the Connector is fixed. * apps/Gateway/Gateway/Event_Channel.cpp: - Only if socket_queue_size > 0, do we set a new value. - In reinitiate_proxy_connection(), we must unbind the proxy from the proxy_map_ as we are no longer responsible for this. The Connector should now be responsible for this. * apps/Gateway/Gateway/Concrete_Proxy_Handlers.cpp: Added necessary DLL build macros. * apps/Gateway/Peer/Peer.cpp: - Added include file and necessary DLL build macros. - Removed error checking for Reactor::remove_handler() for STDIN as STDIN is never registered with the Reactor on Win32. - Fixed the registration of SIGINT. * apps/Gateway/{Peer,Gateway}: Added Win32 makefiles. * ace/ACE.cpp (read_adapter): Handle for the read_adapter should always be STDIN. Fri May 16 18:43:17 1997 Nanbor Wang * ace/config-freebsd.h: Minor modification for working on FreeBSD 2.1.x platform. Added includion of and . Defined ACE_HAS_POSIX_TIME for 2.1.x. Redefine timespec to timeval to hack around a bug on 2.1.x. Thanks to Satoshi Ueno for reporting this. Fri May 16 12:25:32 1997 Douglas C. Schmidt * netsvcs/lib: Reverted back to the original Server_Logging_Handler behavior since the new version is breaking GCC's templates. * ace/Log_Record.h: need to #include "ace/ACE.h" before "ace/Log_Priority.h" so that "Log_Priority.h" sees the configuration stuff (otherwise the following fix won't work). * ace/Log_Priority.h: Added a workaround for lame C++ compilers like the one on HP/UX that can't support large enums. Thanks to Robert Head for reporting this. * ace/Singleton: Added the new ACE_TSS_Singleton, which stores Singletons in thread-specific storage. Thanks to Chris Lahey and Rich Christy for this. * ace/OS.h: Removed the ACE_Singleton_Strategy since we don't need it anymore. * netsvcs/lib: Added the new Server_Logging_Handler_T.* and Log_Message_Receiver.* netsvcs. Thanks to Per Andersson for contributing these. * examples/Misc/Makefile: Removed the XtReactor tests from the Makefile until we figure out a good way to get them integrated with the appropriate libraries. * ace/config-irix6.2-sgic++-nothread.h: Added the following: ACE_LACKS_LINEBUFFERED_STREAMBUF ACE_HAS_SETOWN ACE_HAS_SYSENT_H ACE_HAS_SYSINFO Thanks to Torbjorn Lindgren for reporting this. * ace/Proactor.cpp: Changed the use of lock() to mutex() since we changed the name in Timer_Queue. * ace/Timer_Queue_T.i: Changed the name of the lock() method to mutex() to work around compile problems with HP/UX. Thanks to Robert Head for reporting this workaround. * ace/config-irix5.3-sgic++.h: Made a few changes to get ACE to work on IRIX 5.3. Thanks to Eugene R. Somdahl for these fixes. * ace/OS: Added calloc() implementation. I don't know how this managed to fall through the cracks! * include/makeinclude/platform_osf1_4.0.GNU: Added a few more tweaks courtesy of James Johnson. * include/makeinclude/platform_osf1_3.2.GNU: Added a few more tweaks courtesy of Tom Dobridge. * include/makeinclude/platform_osf1_4.0.GNU (DLD): Added -shared -expect_unresolved '*' so that calls to the linker via cxx will work correctly. Thanks to Thilo for this. * include/makeinclude/platform_chorus.GNU: Removed CLASSIXDIR = /usr/home/chiang/chorus/merge/extended-i386at, added the nostdinc flag, and removed extra whitespace. Thanks to Wei Chiang for reporting this. Fri May 16 00:02:33 1997 * ace/ReactorEx: Even though changes to the owner field are very well synchronized within the class code, the owner() accessor is public and can be called from out side the class. Therefore, I have added a owner_i() that does not do locking. All internal calls to check the owner will use the new accessor, whereas application code outside the class can still use the old synchronized accessor. Fri May 16 11:39:51 1997 Nanbor Wang * ace/OS.i (sigaddset, sigdelset, sigemptyset, sigfillset, sigismember): Added implementation when ACE_LACKS_SIGSET so that platforms (NT?) without these functions can still manipulate sigset_t variables. Thu May 15 22:19:59 1997 Douglas C. Schmidt * examples/ASX/Event_Server/Event_Server: Removed the THR_DETACHED flag from options so that we can wait on the threads correctly. * ace/Stream_Modules.cpp: Changed the logic for determining when to compile the Stream_Modules.cpp code. Now, we compile it unless ACE_LACKS_STREAM_MODULES is defined (i.e., we're on HP/UX 10.x using aCC). * netsvcs/lib/Server_Logging_Handler.cpp (handle_input): Fixed a bug in handle_input() where we need to return the result, not just 0 or 1. Thanks to Per Andersson for reporting this. * ace/Log_Priority.h: Changed the values of the enums in ACE_Log_Priority so that they can be dealt with via bitwise operations. Thanks to Per Andersson for this. * include/makeinclude/platform_osf1_4.0.GNU: Added support for templates. Thanks to Steve Huston and James Johnson for verifying this. * include/makeinclude/platform_osf1_3.2.GNU: Got rid of all unresolved symbol warnings using cxx 5.5 on DEC/OSF v3.2 by using the linker flag "-expect_unresolved '*'." In addition, I added -threads to the DCFLAGS macro. Thanks to Tom Dobridge for this. * ace/Strategies_T: Added a minor ACE_Reactive_Strategy extension to enable non-blocking I/O in active_svc_handler(). Thanks to Arturo Montes for contributing this. * ace/config-osf1-4.0[-g++].h: Added a #define for ACE_POLL_IS_BROKEN since DEC UNIX's poll() doesn't seem to work correctly as a highres timer. Thanks to James Johnson and Thilo for reporting this. * examples/Threads/thread_specific.cpp (worker): Changes size_t i back to int i to avoid a signed/unsigned complaint. Thanks to David Levine for reporting this. * ace/config-chorus.h: Added ACE_LACKS_MPROTECT, ACE_HAS_IP_MULTICAST, and ACE_LACKS_SOCKETPAIR to the Chorus port. Thanks to Wei Chiang for reporting this. * ace/OS.i: Added ACE_LACKS_ACCESS to the Chorus config file and VxWorks config file, as well as to OS.i. : * ace/OS.i: Added ACE_LACKS_GETSERVBYNAME to the Chorus config file and VxWorks config file, as well as to OS.i. * ace/OS.i: Added ACE_LACKS_SBRK to the Chorus config file, as well as to the definition of the ACE_OS::sbrk() function. * ace/OS.h: Removed #include /**/ from the Chorus-specific part of OS.h since it's already included elsewhere. Thanks to Wei Chiang for reporting this. * ace/Reactor: Added a typedef for ACE_Reactor_Token to ACE_Null_Mutex for situations where ACE_MT_SAFE is *disabled*. This makes the code more consistent. * ace/Reactor: Added an interface that makes it possible to acquire a reference to the that is used to serialize the internal Reactor's processing logic. This can be useful for situations where you need to avoid deadlock efficiently when are used in multiple threads. Thanks to Detlef for pointing out the utility of this. Thu May 15 23:34:30 1997 Tim H. Harrison * ace/Process_Manager.cpp (spawn_n): Changed ACE_Process_Manager::start_n to ACE_Process_Manager::spawn_n. Thu May 15 15:39:13 1997 Carlos O'Ryan * include/makeinclude/platform_hpux.GNU: * ace/config-hpux-10.x.h: * ace/config-hpux-10.x-nothread.h: HP/CXX cannot achieve template closure, not even using the dummy exec trick: apparently the repository gets a bit corrupted. HP/CXX (version 10.24) support explicit template instantiation, I believe this to be a superior method for ensuring library closure (and it works). * ace/Task_T.cpp: * ace/Stream_Modules.cpp: I have changed the hack to compile under HP-UX, "ace/Module.h" is once more included in ace/Task_T.cpp, but "ace/Stream_Modules.cpp" is protected: it will be empty under HP-UX unless included from the "ace/Stream_Modules.h". I still believe that there is a problem in the cyclic dependancy Task -> Module -> Thru_Task -> Task; but it seems that the current hack works better. * ace/OS.h: Defining ACE_UNUSED_ARG as (a) for HP/CXX does not work so I moved it to the SGI and GCC definition. * ace/OS.i: More unused args. * ace/Handle_Set.h: Removed the extra qualification for ACE_Handle_Set::NBITS, HP/CXX sends a lot of warnings with that. * ace/IOStream.h: It included "IOStream.cpp" I think that "ace/IOStream.cpp" is better. * ace/Local_Name_Space_T.h: Ditto for "Local_Name_Space.h" Thu May 15 17:40:06 1997 * ace/ReactorEx.i (owner): Since changes to the owner field are very well synchronized, we do not need to synchronize this accessor. * ace/IOStream.h: Added /**/ after #include directives. * ace: Update Win32 makefiles to include UNICODE make option. Thu May 15 08:54:53 1997 David L. Levine * Makefile (release, cleanrelease): use -prune option to "find" instead of filtering its output. Thanks to Chris Cleeland for suggesting this. Wed May 14 21:52:22 1997 Douglas C. Schmidt * ace/UPIPE_Stream.cpp (control): We need to "cast away const" so that this method can call the Stream's control() method (which is non-const). Thanks to David Levine for locating this. * ace/Singleton.cpp: Finished re-implementing ACE_Singleton. * examples/ASX/Message_Queue/buffer_stream.cpp: Updated this example to illustrate (1) how filters work in an ACE_Stream and (2) to make sure that resizing buffers work. * ace/UPIPE_Stream.h: Changed the signature of control() to take an int so that it will match the base class signature. * ace/Singleton.h: The new ACE_SingletonEx isn't working yet. I've #ifdef'd it out until it works. * examples/Threads/tss2.cpp: Updated this test program to illustrate the use of the new ACE_SingletonEx class. * ace/Singleton.h: Added a new instance() method to the ACE Singleton that can be used to set the Singleton. This is useful for situations where the type being used as the Singleton doesn't have a default constructor. Thanks to Arturo Montes for this suggestion. * ace/Singleton: Factored out common code in the Singleton and SingletonEx implementations so they will be cleaner and more portable. * ace/Local_Name_Space_T.h, ace/Map_Manager.h, ace/Hash_Map_Manager.h, ace/SString.h, ace/Hash_Map_Manager.cpp: Changed all uses of the identifier "allocator" to "alloc" to avoid conflicts with MSVC++ STL 5.0. Thanks to William L. Gerecke for reporting this. * ace/config-aix-4.[12].x.h: Replaces ACE_LACKS_PTHREAD_THR_SIGSETMASK with ACE_HAS_SIGTHREADMASK. Thanks to Chris Lahey for this. * ace/OS.i (thr_sigsetmask): Added the ACE_HAS_SIGTHREADMASK support for AIX. Thanks to Chris Lahey for this. * ace/Singleton: Added the new ACE_SingletonEx, which supports both heap-based and thread-specific storage-based Singletons. Thanks to Chris Lahey for this. * ace/OS.h: Added the new ACE_Singleton_Strategy to OS.h. Thanks to Chris Lahey for this. Wed May 14 16:32:57 1997 David L. Levine * Makefile: use cpio instead of tar to allow easy filtering of CVS files from the release. Wed May 14 15:00:58 1997 * examples/IPC_SAP/SOCK_SAP/CPP-inclient.cpp (main): Fixed code. * examples/Naming: Replaced multiple makefiles with one makefile. * ace/OS.h: Added UNICODE support for some #defines. * OS.i (vsprintf): Added support for this in ACE_OS. * OS.cpp (socket_init && socket_fini): It is ok to print out cout and cerr messages from here (as the C runtime library is still attached) but it is *not* ok to print out ACE_DEBUG messages. God only knows the state of the thread specific LogMsg instance when the process reaches this piece of code. Also added a (handy) sprintf that has the following prototype: sprintf (wchar_t *buf, const char *format, ...) * ace/Process: UNICODE fixes. * tests: Fixed the following such that they work with UNICODE: Pipe_Test.cpp Process_Mutex_Test.cpp Process_Strategy_Test.cpp Time_Service_Test.cpp Tokens_Test.cpp * Time_Service_Test.cpp (main): Fixed typo in the svc.conf filename for the clerk. Tue May 13 18:56:27 1997 Douglas C. Schmidt * ace/IOStream.h: To make C++ compilers happy I added the following changes by modifying ACE_IOStream & operator>>( ACE_Time_Value *& tv ); to be ACE_IOStream & operator>>( ACE_Time_Value *& tv ); Thanks to Chuck Gehr for this fix. Tue May 13 21:32:12 1997 David L. Levine * ace/Process.cpp (~ACE_Process_Options): delete command_line_buf_ was missing the []. * examples/Threads/process_manager.cpp (main): avoid compiler warning due to implicit creation of temporary by explicitly creating an ACE_Process_Options instance. It gets passed to ACE_Process_Manager::spawn (ACE_Process_Options &), which takes a non-const reference. Tue May 13 18:08:32 1997 * examples/ASX/UPIPE_Event_Server: Made enough fixes for this to compile on Win32 but more work need to be done for this to work on Win32. * ace/OS.i (kill): The error result for ::OpenProcess() is null and *not* invalid handle. * ace/Process.i (kill): Changed the implementation to remove the ACE_OS::kill() code from ACE_Process::kill() for Win32. This allows us to avoid calling ::OpenProcess() unnecessarily. * tests: For Win32, added Reactor_Exceptions_Test and Priority_Tasks_Tests. Files changes include run_tests.bat, tests.mak, and tests.mdp. * tests/Future_Test.cpp (main): Fixed memory leaks in main() and in name_i(). * tests/Thread_Pool_Test.cpp (open): The loop was messed up causing memory leaks. I fixed it. * ace/UPIPE_Stream.cpp (close): I am not sure why the stream was closed with M_DELETE_NONE. This indicates that close() should not delete any Tasks. This caused a memory leak as the Tasks in the Tail and Head modules were not deleted. I have removed this to fix the memory leak. Also added a destructor such that mb_last_ is released if it is still around. Tue May 13 16:48:18 1997 James C Hu * ace/Process.cpp: Added implementations to new interfaces to ACE_Process_Options::setenv (char *envp[]), and ACE_Process_Options::command_line (char *argv[]). * apps/JAWS/server/HTTP_Response.cpp: Required changes so that CGI processing will work with the new ACE_Process class. * apps/JAWS/stress_testing/benchd.cpp: Requried changes due to changes in the ACE_Process interface. Tue May 13 15:22:01 1997 Tim H. Harrison * ace/Process_Manager.h: Changed ACE_Process_Manager::start to ACE_Process_Manager::spawn. * ace/Process.cpp (spawn): The check for a null environment argv was incorrect. Thanks to Nanbor for finding this. Mon May 12 18:59:39 1997 David L. Levine * ace/config-mvs.h: conditionally use ACE_HAS_UCONTEXT_T or ACE_LACKS_UCONTEXT_H depending on __COMPILER_VER__. Thanks to Chuck Gehr for this fix. * OS.h, OS.cpp (thr_create), Task.h, Thread.h, Thread_Manager.h: use ACE_DEFAULT_THREAD_PRIORITY instead of -1, because -1 is a valid priority on Win32. Thanks to Irfan for discovering this problem with Priority_Task_Test. * ace/Thread_Manager.cpp (wait_grp,wait_task): changed type of loop index "i" from size_t to int to avoid signed/unsigned comparison. Mon May 12 18:41:19 1997 Nanbor Wang * ace/config-freebsd-pthread.h: * ace/config-freebsd.h: Added ACE_LACKS_RWLOCK_T to FreeBSD config files. Thanks to Amancio Hasty for noticing this. Mon May 12 17:11:50 1997 Tim H. Harrison * ace/Process.h: Changed ACE_Process::start to ACE_Process::spawn. Added new argv-style methods for ACE_Process::setenv and ACE_Process::command_line. These new argv-style methods do not have implementations yet. Mon May 12 15:27:41 1997 Douglas C. Schmidt * ace/config-aix-4.[12].x.h: Added ACE_HAS_EXCEPTIONS to the AIX 4.* config files. Thanks to Chris Lahey for this. Mon May 12 13:49:54 1997 * ace/Thread_Manager.cpp (wait): We have to make sure that while we wait for these threads to exit, we do not have the lock. Therefore we make a copy of all interesting entries and let go of the lock. We then do the join(). * ace/Task.cpp (wait): Removed the extra locking in wait(). The Thread Manager will handle this correctly. * ace/ACE.cpp (register_stdin_handler): Changed the options such that the Thread Manager used for the adapter is passed along to the method executed by the new thread. We can then notify the thread manager when this adapter thread exits. * examples/ASX/Event_Server/Event_Server: Changed the way the reference count was being kept on the context. Now, the reference count starts with zero and every instance and every active Task increments it. This works well as Task::close() is called one from the module being deleted and from the active thread going away. Mon May 12 11:11:51 1997 * ace/Process.*: Removed the old ACE_Process and replaced it with what was ACE_ProcessEx. * ace/Process_Manager.{i,cpp}: Updated to use the new ACE_Process API. Mon May 12 08:16:38 1997 David L. Levine * ace/config-freebsd*.h: added support for FreeBSD 2.1.7R. Thanks to Satoshi Ueno for figuring out the differences and to Nanbor Wang for updating the config files. Sun May 11 17:36:59 1997 * tests/{Pipe_Test.cpp, Process_Mutex_Test.cpp, Time_Service_Test.cpp, Token_Service_Test.cpp}: Updated these files to use the new ACE_Process API. Sun May 11 14:40:51 1997 David L. Levine * ace/config-osf1-4.0.h: put back ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS. * ace/ACE_Process.cpp (ACE_Process_Options ctor): reordered initializers to match declaration order. Sat May 10 19:44:28 1997 * Process.h: ACE_ProcessEx now works on Solaris and NT. There have been some changes to the API. ACE_ProcessEx::cl_options and ACE_ProcessEx::path have been combined into ACE_ProcessEx::command_line. ACE_ProcessEx::command_line must be used to specify path and command-line arguments. There is also a second ACE_ProcessEx::setenv method that allows applications to set environment variables in a "VAR=VALUE" format. Sat May 10 10:51:11 1997 Douglas C. Schmidt * ace/config-osf1-3.2.h: Added three new flags to the config file for OSF/1 3.2: #define ACE_LACKS_SETSCHED #define ACE_LACKS_RWLOCK_T #define ACE_LACKS_GETPGID Thanks to Tom Dobridge for reporting this. Fri May 09 16:37:48 1997 David L. Levine * ace/config-osf1-4.0.h: added DEC_CXX. * ace/config-osf1-4.0-g++.h: removed commented-out ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS. Thanks to Thilo Kielmann for patches for the above two OSF config files. * ace/Sched_Params.cpp (priority_min): On Solaris (with STHREADS), don't return priority of 0 because ::pthread_attr_setschedparam () will refuse to use it (with EINVAL). So, bump priority of 0 up to 1. * tests/Priority_Task_Test.cpp: retry the task activation with priority 0 if it fails with non-zero priority. This lets the test run on platforms such as Linux that only let the superuser set non-zero priority. * ace/ACE_Process.cpp (ACE_Process_Options ctor): reordered initializers to match declaration order. * examples/Connection/non_blocking/test_lsock_acceptor.cpp: fixed typo in template specializations: ACE_LSOCK_ACCEPTOR instead of ACE_SOCK_LACCEPTOR. Fri May 9 13:07:20 1997 Douglas C. Schmidt * ace/UNIX_Addr: Changed the return values of all the set() methods so that they conform to the signature used by the INET_Addrs. * examples/Connection/non-blocking: Added two new test programs, test_lsock_{connector,acceptor}.cpp that * ace/LSOCK_Stream.cpp: Revised the get_remote_addr() method so that it uses the underlying ACE_SOCK::get_remote_addr() method rather than the get_local_addr() method. Hopefully, this will fix an ACE bug with UNIX domain sockets. Thanks to Paul Han for reporting the problem and the fix. * include/makeinclude/platform_aix4.2.GNU (LLIBS): Changed LLIBS = -lC_r -lC -lpthreads -lbsd -ltli_r -ldl -lc_r -lm -lc $(ACELIB) to LLIBS = -ltli_r -ldl $(ACELIB) MakeC++SharedLib_r includes all the other libs automatically in the search. * apps/Gateway/Gateway/Proxy_Handler.h: Moved the handle_close() method into the public section since the Connector now calls it. * ace/Containers.cpp: Updated all the operator= methods so that they no longer try to return *this. Thanks to Chris Lahey for reporting this. * ace/IOStream.h: Replaced __alpha with DIGITAL_UNIX && DEC_CXX. Thanks to Thilo for reporting this. * build/gcc/tests/Simple_Message_Block_Test.cpp (main): Changed the use of ACE_Mutex to ACE_SYNCH_MUTEX so that everything will build correctly on non-MT platforms. * ace/Timer_{Heap,List}_T.cpp: To ensure backwards compatibility with the old "int" return value of Timer_*::schedule() we must cast the long value to int before returning it. Thanks to Thilo Kielmann for reporting this. * ace/Acceptor.cpp, ace/Connector.cpp: If an active or passive connection times out and the Connector or Acceptor calls the handle_timeout() method of the Svc_Handler, we now keep track of whether the handle_timeout() method returns -1. If so, we call handle_close() on the Svc_Handler automatically. Thanks to Michael Hartman for suggesting this. * tests/IOStream_Test.cpp: Fixed this test so that it runs on non-MT platforms. * ace/Module.cpp: Changed the implementation of the close_i() method so that it will wait for all active threads in a Task to exit before deleting the task. * ace/Task: Added a wait() method on an ACE_Task that will use the new ACE_Thread_Manager::wait_task() method to block until all threads have shutdown in a Task. * ace/Thread_Manager: Finally implemented the wait_task() and wait_grp() interfaces on ACE_Thread_Manager. * ace/SOCK_Dgram.cpp: Added a timed recv() operation. Thanks to Hongbo Xu for contributing this. * ace/Timer_Queue_T.cpp: Added #include "ace/Synch.h" to keep the DEC C++ compiler happy. Thanks to James CE Johnson for this. * ace/Containers.i (size): Changed to so that this compiles on the Alpha. Thanks to James CE Johnson for this. * ace/IOStream.h: Include the std_macros header on the Alpha. Thanks to James CE Johnson for this. * include/makeinclude/platform_osf1_4.0.GNU (SOBUILD): Removed -lACE from the link line. Thanks to James CE Johnson for this. * tests/Timer_Queue_Test.cpp: Changed all the int timer ids to long so that the test will work on DEC ALPHAs. Thanks to Thilo Kielmann for reporting this. * ace/Process: Fixed a number of compile problems for UNIX. * ace/Process.h: Changed the methods named stdin/stdout/stderr to std_in/std_out/std_err to avoid name clashes with the standard C library. * ace/OS: Changed the use of ACE_Unbounded_Set to ACE_Unbounded_Stack in order to get the appropriate semantics for TSS cleanup on NT. * ace/Containers: Enhanced the ACE_Unbounded_Stack class so that it supports insert()/remove()/find() methods. These rather unorthodox methods are useful for implementing the TSS semantics required by OS.cpp. * ace/Containers: Revised all the interfaces for the various containers so that they all have the same "look and feel." Fri May 9 00:00:21 1997 James C Hu * apps/JAWS/server/HTTP_Request.{h,cpp}: Added a uritopath translation method, so that CGI location can be computed as it is searched. Added methods to access the parsed headers. * apps/JAWS/server/HTTP_Response.{h,cpp}: Flushed out the implementation of cgi_response () method. If all goes well, it should be able to execute a CGI program. I don't set the IO handles to point at the socket handle yet. * apps/JAWS/server/README: Updated description of JAWS behavior. Thu May 8 18:04:14 1997 Irfan Pyarali * ace/Containers: Made the return values of Container methods more consistant with other components of ACE (i.e., 0 for success, -1 for failure). * ace/Containers (ACE_Unbounded_Stack::delete_all_nodes): Fixed subtle bug in delete_all_nodes. * ace/OS.cpp (ACE_TSS_Cleanup::exit): Changed because of return value changes in ACE containers. * Containers: Added size methods to stack containers and consolidated friendship between ACE_Unbounded_Stack_Iterator and ACE_Unbounded_Stack * tests/Message_Block_Test.cpp: I was incorrect about each data block having its own lock. Since *many* data blocks can share the same lock, for the case of message block chains, we would like to optimize locking. Therefore, the first guy in the chain grabs the lock and passes it to the continuation chain. When each guy in the chain gets it, it compares the passed lock to its own locking strategy. If it is the same lock, no need to acquire the lock again. If our lock is different, then we do our own locking. * tests/Simple_Message_Block_Test.cpp: This test program is a torture test that illustrates how ACE_Message_Block reference counting works, how and when locks are used, how memory is managed, and how continuation chains of message blocks are made. Ideally used with purify :-) * tests: Added new test. Following changed: Makefile run_tests.bat run_tests.sh tests.mak tests.mdp Thu May 8 18:04:14 1997 James C Hu * include/makeinclude/platform_irix6.2_sgic++.GNU: Moved SGI C++ options out of CPPFLAGS into CCFLAGS so that gcc won't emit diagnostics during a make depend. Thu May 8 11:52:41 1997 Chris Cleeland * ace/{Task,Thread}.h: Added documentation describing thread priority determination to methods where priority is an [optional] argument. Note that if you want to inspect the REAL documentation, you should look at the code for ACE_OS::thr_create(). But that's convoluted and touchy. * ace/Strategies_T.h (ACE_Cached_Connection_Strategy): Added documentation for this class. Thu May 08 00:10:00 1997 * ace/Process.*: This is the first pass at the new ACE_Process class. It is now called ACE_ProcessEx. When it is completely ported to Solaris, we'll replace the current ACE_Process with ACE_ProcessEx. * examples/OS/Process/process.cpp: Added some examples for the new ACE_ProcessEx. Wed May 07 21:58:29 1997 * ace/Message_Block.h: ACE_Data_Block calling delete on the ACE_Message_Block was incorrect. This was a hack to simplify the locking issues! However this optimization leaded to incorrect code. Therefore I have taken this behavior out. The new implementation will lock and unlock multiple times in the case when there are message_blocks in the continuation field, all of which point to same data block. However, this is a strange case that can be optimized later. For now correct code is more important. Also, the continuation message blocks are only deleted in the release() method and not in the destructor. This will ensure that if message blocks of the stack are chained together, we will not call release on message blocks of the stack. Also note that release() should only be called on message blocks that have been dynamically allocated. Message blocks of the stack will clean up properly when the activation record of the method completes. Dynamically allocated messages blocks should *never* be chained with message blocks allocated of the stack. * examples/ASX/Event_Server/Event_Server/Peer_Router.h: Removed empty definitions of assignment operator and copy constructor. * examples/ASX/Event_Server/Event_Server/event_server.cpp (handle_input): Added code here will make sure we actually wait for the user to type something. On platforms like Win32, handle_input() is called prematurely (even when there is no data). * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: Changed a log message. Wed May 7 22:55:00 1997 James C Hu * JAWS/server/*: Debugging changes! GET and HEAD both work now. As well as changes to make it compile cleanly on VXWORKS, as reported by David. Wed May 07 16:05:39 1997 David L. Levine * ace/Makefile: added Timer_Wheel to FILES. Thanks to Thilo Kielmann for reporting this. * include/makeinclude/platform_irix6.2_sgic++.GNU: enabled CPPFLAGS to instantiate all templates so that gatewayd will build. Thanks to Nathan N. Vuong for reporting this problem and Eric Dean Russell for supplying and the fix. * ace/Map_Manager.h: updated comments to indicate that find functions return a non-negative integer if the item is found. * ace/Map_Manager.cpp (find_i (const EXT_ID &, INT_ID &)): return index instead of 0 if the item is found, to be consistent with find_i (const EXT_ID &). * ace/IOStream.cpp (ACE_Streambuf_T ctor): added initializations of eback_saved_ and pbase_saved_ to avoid unitialized memory read reports from Purify. Tue May 6 07:39:25 1997 Douglas C. Schmidt * ace/Service_Config.cpp (open): Make sure to perform the daemonization logic first so that we get a new process created before initializing reactors, etc. Thanks to Adrian Salt for reporting this. * examples/IPC_SAP/SOCK_SAP/CPP-inserver-poll.cpp (main): Changed ACE::INVALID_HANDLE to ACE_INVALID_HANDLE. Thanks to Dani Flexer for reporting this. * tests/Conn_Test.cpp (compare_i): Changed the comparison from a1 == a2 to a1 != a2 since this appears to be what is needed. We need to improve the comments here! * tests/Conn_Test.cpp: Split the definition of the Svc_Handler template into its own Conn_Test.h file to work around "features" with AIX C++. Thanks to Chris Lahey for reporting this. * ace/Containers.cpp: Fixed a bug in the set() method for ACE_Unbounded_Queue. Again, thank goodness for cs242! * ace/Containers.cpp: Fixed a bug in the enqueue_head() logic for ACE_Unbounded_Queue. Thank goodness for cs242 ;-). * ace/Containers.cpp: Added a destructor for ACE_Node to keep the compilers happy. Tue May 06 11:31:49 1997 David L. Levine * netsvcs/lib/*.cpp: removed break statements after ACE_RETURNs to avoid unreachable statement warnings from GHS. * ace/OS.cpp (mktime): added time_t cast of -1 (error) return to avoid compiler warning. * ace/config-vxworks-ghs-1.8.h: added ACE_LACKS_SIGNED_CHAR. * ace/Containers.cpp (dequeue_head): fixed typos in variable names. * examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp: removed #ifdef ACE_HAS_TLI around some template specializations so that this subproject will build on platforms non-TLI platforms such as Linux. Tue May 6 17:02:54 1997 James C Hu * ace/OS.{h,i}: Added strftime (). Also, enhanced strcasecmp implementation to account for lexicographical ordering for mismatches. * apps/JAWS/server/Parse_Headers.{h,cpp} (class Headers_Map): Changed signature of casting operator to return a pointer rather than a reference to a constant pointer, to fix anachronism warning Doug found. * apps/JAWS/server/HTTP_Config.{h,cpp}: Added class HTTP_Config to be a container for HTTP server options such as locations of directories, port, etc. * apps/JAWS/server/HTTP_Helpers.{h,cpp}: Added code to enhance support for CGI scripts: - Added HTTP_decode_string to HTTP_Helper class, to deal with percent codes. * apps/JAWS/server/HTTP_Request.{h,cpp}: Added code to enhance support for CGI scripts: - Added cgi_, cgi_env_, and cgi_args_ data members to and corresponding accessors. - Added nice accessors to the important data members to simplify other parts of the code. - Added method to parse URI to determine the name of the CGI executable if present. * apps/JAWS/server/HTTP_Response.{h,cpp}: Added code to enhance support for CGI scripts: - Hooks are now present to make the appropriate calls to activate a CGI program. * apps/JAWS/server/*.{h,cpp} Various changes from the ACE mailing list incorporated. Cosmetic changes for ACE coding style. SGI fixes. Tue May 6 00:00:54 1997 Chris Cleeland * ace/Message_Block.cpp: Added template specialization for ACE_Guard<> that prevented ACE from compiling under Linux. Mon May 5 22:17:15 1997 Sumedh Mungee * apps/JAWS/stress_testing: Removed the usleep definition from global.h, it was unused by the program. Mon May 05 21:01:42 1997 David L. Levine * ace/config-linux*.h: added ACE_HAS_STRING_CLASS. Thanks to Luis Lopes for reporting this. Mon May 05 19:58:16 1997 * ace/ace.{mak,mdp}: Readded IOStream.cpp to the makefile. * ace/Synch_T.h: Added ACE_SYNCH_RECURSIVE_MUTEX. * ace/Timer_Queue: Added an extra template parameter to Timer_Queues that specifies the type of locking to be used inside of the timer queue. Also changed the functor callback routines so that they are more descriptive compared to operator (). Mon May 5 21:37:01 1997 Douglas C. Schmidt * ace/Message_Block: Revised the release() logic for ACE_Message_Block and ACE_Data_Block so that we will delete both within the same block of code in order to hold the lock. This should prevent nasty race conditions in multi-threaded programs. Thanks to Craig Perras for reporting this problem. * ace/Message_Block.cpp: Replaced an explicit acquire()/release() of ACE_Lock::locking_strategy_ with a call to an ACE_Guard. * ace/Containers.cpp (set): Optimized for the common case where we're increasing the size of the set by 1. * ace/Containers: Merged the ACE_Set_Node, ACE_Stack_Node, and ACE_Set_Node into a single "ACE_Node" class. This tidies up the code quite a bit. * ace: Removed the Set.* and Stack.* files and replaced them with the Containers.* files. This file contains the ACE_*Stack, ACE_*Queue, and ACE_*Set classes. If this revised file scheme breaks existing code please let me know and I'll provide backwards compatibility. * ace/Stack: Changed the name of ACE_Unbounded_Queue::enqueue() to ACE_Unbounded_Queue::enqueue_tail() and also added ACE_Unbounded_Queue::enqueue_head(). * ace/OS: Changed the names of the parameters of the ACE_OS::mem* methods from ACE_OS::mem* (void *s, const void *t) to ACE_OS::mem* (void *t, const void *s) since "t" should stand for "target" and "s" for "source." Thanks to Andres Kruse for pointing this out. * ace/Stack: Removed the peek() method from ACE_Unbounded_Queue. This functionality is now subsumed by the get(..., 0) method. If this breaks any existing code please let me know. * ace/Stack.h: Moved all the functionality from ACE_Unbounded_Set into ACE_Unbounded_Queue. That's really where this belonged in the first place. Thanks to David Levine for noticing this. * ace/Set.h: Moved ACE_Set_Node from the *.cpp file into the *.cpp file in anticipation of AIX C++ compiler bugs ;-). * examples/ASX/Event_Server/Transceiver/transceiver.cpp: Rearranged the location where we register to receive standard input so that the socket handle will not be initialized at this point. Thanks to craig perras for reporting this. * examples/ASX/Event_Server/Transceiver/transceiver.cpp (Event_Transceiver): Make sure to #ifdef around SIGQUIT for WIN32 since it lacks this signal. Thanks to craig perras for reporting this. * ace/config-osf1-4.0-g++.h: Removed the ACE_LACKS_SIGNED_CHAR since this seems to be compiler specific. Thanks to Thilo for this insight. * ace/Strategies_T: Added a number of fixes and enhancements to the new Hash_Addr and ACE_Cached_Connect_Strategy classes. * ace/Strategies_T.h: Added #include for "Hash_Map_Manager.h". Thanks to Amos Shapira for reporting this. * ace/config-hpux-10.*.h: Applied a number of patches courtesy of Carlos O'Ryan. * ace/Dump.cpp: Changed a cast from delete (ACE_Dumpable_Ptr *) this->dumper_; to delete (ACE_Dumpable *) this->dumper_; This fixes a potential bug. Thanks to Carlos O'Ryan for this bug report. * ace/DEV_IO.h, * ace/SPIPE_Stream.h: Removed the = 0 default value for one send() method to avoid ambiguity with the other send() method. Thanks to Carlos O'Ryan for this bug report. * ace/Map_Manager.cpp (advance): Removed a cast to size_t since that is always true. Thanks to David Levine for pointing this out. * ace/XtReactor: Moved the remove_handler_i() and register_handler_i() methods into the protected portion of the class. Since these should never be called by the client I've moved them into protected portion to ensure this is the case. * ace/XtReactor: Changed the implementation of the XtReactor to use long for dealing with timers. Thanks to Stuart Powell for reporting this. Mon May 5 17:16:41 1997 Carlos O'Ryan * ace/config-hpux-10.x.h, config-hpux-10.x-nothread.h: Some patches are needed to compile ACE under HP-UX (using HP/C++), I documented those patches. Mon May 05 11:50:39 1997 David L. Levine * netsvcs/lib/Server_Logging_Handler.cpp: fixed ACE_Svc_Handler specializations, yet again, for Linux w/LXPthreads. Thanks to Luis Lopes for reporting this problem with sufficient detail for us to track it down. * ace/Stack.* (ACE_Unbounded_Queue): 1) made peek () const. 2) added another peek (u_int index = 0) function that can peek at any queue item, not just the first. It returns a pointer to the item (or 0 if not found), to avoid copying. 3) changed return type of size () from int to size_t. 4) inlined size (). * ace/Strategies_T.cpp (connect_svc_handler, operator==): added return type. * netsvcs/lib/Server_Logging_Handler.cpp: fixed template specializations for platforms that have neither THREADS nor TLI. Thanks to Nanbor Wang for reporting this. Sun May 4 12:34:09 1997 Douglas C. Schmidt * ace/OS.cpp: If ACE_HAS_THREADS isn't defined then we'll just use mktime() without the locking. * ace/Set: Removed the get() methods from the ACE_Fixed_Set and ACE_Bounded_Set since they don't make much sense on these abstractions. * ace/Set: Changed the new "find" method to be called "get" to correspond to the new "set" method I'm adding. * ace/SString.cpp: Added a operator << for ACE_CString in order to print it with iostreams. * ace/Set.cpp: Added a reset method to the ACE_Unbounded_Set to remove all the nodes without completely destroying the set. * ace/SString: Added friend operator+ to both ACE_CString and ACE_WString in order to provide a concatenation operator. * ace/SString: Added a compare() method to all the ACE String classes. This behaves just like the Standard C library strcmp() function. * ace/Message_Queue.i: Oddly, there were a bunch of methods defined in this *.i file that didn't have ACE_INLINE in front of them. I'm surprised this didn't give compile errors on some platforms. I've fixed this by moving these methods into the *.cpp file. * ace/Stream, ace/Service_Repository, ace/Reactor, ace/Message_Queue, ace/Map_Manager, ace/Malloc_T, ace/Hash_Map_Manager, ace/Set: Added a done() method on all the iterators so that we can check within the iteration itself to see if there are any remaining elements. In addition, updated the return value of advance() on all iterators so that it returns 1 if we're not done and 0 if we're done. Sun May 04 07:22:49 1997 David L. Levine * ace/Timer_Heap_T.cpp: changed some more int declarations to longs. Sat May 3 17:38:19 1997 Douglas C. Schmidt * Changed all uses of Reactor::{scheduler_timer,cancel}() and Timer_{Queue,List,Heap,Wheel}::{schedule,cancel}() to use long rather than int. This is important since it ensures that we can make the Timing Wheels trick of casting the Timer_Node * to long work correctly on machines that have 64 bit pointers, 64 bit longs, and 32 bit ints (e.g,. DEC ALPHA). Thanks to Thilo Kielmann for pointing this out, even though he finds this solution distasteful ;-). * netsvcs/lib/TS_Clerk_Handler.cpp (initiate_connection): I believe there was also a bug here -- if schedule_timer() returns 0 that's not an error! * apps/Gateway/Gateway/Proxy_Handler_Connector.cpp (initiate_connection): I believe there was a bug here -- if schedule_timer() returns 0 that's not an error! * tests/IOStream_Test.cpp: Added some minor changes for DEC UNIX. Thanks to James CE Johnson for reporting this. * ace/IOStream: Added a number of minor changes for DEC UNIX. Thanks to James CE Johnson for reporting this. * ace/config-osf1-4.0.h: Added ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS to the config.h file. Thanks to James CE Johnson for reporting this. * ace/SString: Made the ace_string_null_string_ a static data member rather than an external constant. This should control the name space a bit better. * ace/SString.cpp: Fixed the ACE_CString::operator += so that it won't screw up if this->rep_ initially points to the ACE_String_null_string_. * examples/Misc: Added a new test_set.cpp program that exercises the ACE_*_Set classes. Sat May 03 06:56:10 1997 David L. Levine * ace/Map_Manager.cpp (dtor): removed void return (typo). * ace/Set.cpp (ACE_Fixed_Set::operator =): typo: fs instead of bs. * ace/Set.cpp (ACE_Fixed_Set::find): typo: index instead of i. * ace/IOStream.cpp: fixed typo: "#if defined" instead of just "#if". * tests/Conn_Test.cpp, netsvcs/lib/{Client_Logging_Handler,TS_Clerk_Handler}.cpp, netsvcs/clients/Tokens/manual/manual.cpp, apps/Gateway/Gateway/Event_Channel.cpp,: apps/JAWS/client/Blob.cpp, examples/ASX/Event_Server/Event_Server/Peer_Router.cpp, examples/ASX/Event_Server/Transceiver/transceiver.cpp, examples/ASX/UPIPE_Event_Server/{Consumer,Supplier}_Router.cpp, examples/Connection/misc/test_upipe.cpp, examples/Connection/non_blocking/test_*_connector.cpp: added ACE_Map_Entry template specialization. It's needed now that the destructor is explicit. Fri May 2 14:57:56 1997 Douglas C. Schmidt * ace/Map_Manager.cpp: Added a no-op destructor to ACE_Map_Entry just to keep some compilers happy. Thanks to Chuck Gehr for reporting this. * ace/config-osf1-4.0.h: Added #define ACE_LACKS_IOSTREAM_FX #define ACE_LACKS_LINEBUFFERED_STREAMBUF #define ACE_LACKS_SIGNED_CHAR Thanks to James CE Johnson for reporting this. * ace/Timer_{Wheel,Heap,List}_T.h: Fixed a typo in all these classes that was failing to put the keyword "class" after "friend." Also, replaced the use of the typedef with the expanded name of the class to work around problems with DEC C++. Thanks to James CE Johnson for reporting this. * ace/Set: Added a find() method that will return the "ith" element in the set. * ace/Set: Added copy constructors and assignment operators to all the ACE_*_Set classes. * ace/Set.cpp: Changed the implementation of ACE_Unbounded_Set to use a dummy node and a circular list. This improves performance and also makes it possible to implement "queue" semantics for inserting at the tail of the set. * ace/config-osf1-4.0.h: Added the ACE_HAS_STRING_CLASS macro. Thanks to James CE Johnson for this. * ace/IOStream: Added the ACE_HAS_STRING_CLASS macro to replace the nasty #ifdefs we had previously. Thanks to James CE Johnson for this. * ace/config*.g++: Added ACE_HAS_STRING_CLASS for all the GNU compilers and Win32. * ace/config-mvs.h: Added a new version that contains support for IBM OS/390 r2. Thanks to Chuck Gehr for this. Fri May 02 08:14:30 1997 David L. Levine * examples/ASX/Event_Server/Transceiver/transceiver.cpp: removed specializations of ACE Guards because they're in libGateway. Thanks to Joey Zhu for reporting this problem. * examples/ASX/Event_Server/Transceiver/{Makefile,transceiver.cpp}: added template specializations to transceiver.cpp so that it no longer needs to be linked with libGateway. * examples/ASX/Event_Server/Event_Server/{Makefile,Peer_Router.cpp}: added template specialization to Peer_Router.cpp so that event_server no longer needs to be linked with libGateway. Thanks to Joey Zhu for reporting the above link problems. * apps/Gateway/Peer/{Makefile,Peer.cpp}: added template specialization to Peer.cpp so that peerd no longer needs to be linked with libGateway. * Log_Msg.cpp (VxWorks only): fixed used of ::taskDeleteHookAdd (it should only be called once for all Log_Msg instances) and added call to ::taskDeleteHookDelete to clean up when the last task exits. Thanks to Dave Mayerhoefer for reporting this. * tests/Conn_Test.cpp: changed some fprintf print specifiers to avoid g++ warnings about printing pointer values. Thu May 01 00:05:59 1997 * tests/Time_Service_Test.cpp (main): Made sure that the backing store is not there at the start of the program. We need to make sure because this test kills the Time Clerk and on some platforms the Clerk is not allowed to do a graceful shutdown. By cleaning the backing store here, we are sure that we get a fresh start and no garbage data from a possible aborted run. The old code deleting the backing store at the end of the test is still there but does not work on Win32 as unlink fails with ERROR_ACCESS_DENIED. I am not sure why this is happening! For now the unlink at the start of the program will do. Also added a wait for the clerk before deleting the backing store. This way we are sure that we do not delete the backing store before the clerk is done with it. * netsvcs/lib/TS_Clerk_Handler.cpp: Fixed an obscure bug with ACE_TS_Clerk_Processor. ACE_TS_Clerk_Processor (which is an ACE_Connector) and all its pending connection objects are still registered with the Reactor when the process exits and the Service_Object is deleted. After this the destructor of the Reactor then calls handle_close on ACE_TS_Clerk_Processor (which does not exist anymore), causing a seg fault. The solution is to call ACE_Connector::fini from ACE_TS_Clerk_Processor::fini. ACE_Connector::fini will unregister ACE_TS_Clerk_Processor and all pending connects from the Reactor. Wed Apr 30 17:47:11 1997 Douglas C. Schmidt * ace/OS.i (getpwnam_r): Changed the expression to check if getpwnam_r() returns -1 for AIX. Thanks to Chris Lahey for this. * ace/Timer_Wheel_T.h: changed // = Don't allow these operations for now. ACE_Timer_Wheel_T (const ACE_Timer_Wheel_T &); void operator= (const ACE_Timer_Wheel_T &); to: // = Don't allow these operations for now. ACE_Timer_Wheel_T (const ACE_Timer_Wheel_T &); void operator= (const ACE_Timer_Wheel_T &); Thanks to Chuck Gehr for reporting this. * ace/OS.cpp: Made mktime() thread-safe. If any platforms support multi-thread safe versions of mktime() please let me know so we can set the ACE_HAS_MT_SAFE_MKTIME macro for that config file. * ace/OS.i: Added a new special case for getpwnam_r() on AIX. Thanks to Chris Lahey for reporting this. Wed Apr 30 16:01:04 1997 James C Hu * ace/OS.i, ace/OS.h: added mktime(). Wed Apr 30 14:17:34 1997 David L. Levine * ace/config-vxworks*.h: added ACE_LACKS_PWD_FUNCTIONS. Thanks to Dave Mayerhoefer for reporting this. * ace/OS.i: cleaned up ACE_LACKS_PWD_FUNCTIONS comments a bit. * ace/Array.{h,i}: added const operator []. * ace/Array.cpp (ctors): reordered initializers to match declaration order. * netsvcs/lib/Server_Logging_Handler.cpp: protect against multiple inclusion. Thanks to Kevin Martindale for reporting this problem. Wed Apr 30 08:42:55 1997 Douglas C. Schmidt * ace: Added a new generic Array class, which we'll use until STL becomes more widely portable. * ace: Added a new macro ACE_LACKS_GETPGID to clean up the code in ACE_OS::getpgid(). * ace: Added new config*.h files and platform*.GNU files for FreeBSD. Thanks to Nanbor Wang for these. Wed Apr 30 07:44:36 1997 David L. Levine * ace/config-osf1-4.0*.h: removed ACE_HAS_SIGWAIT. * ace/OS.{h,i}: applied Thilo's patch for sigwait on Digital Unix 4.0, which defines sigwait as a macro. Thanks to Thilo Kielmann for this and the above config file patches. * ace/IOStream.{h,cpp}: James CE Johnson updated the IOStream class; see comments in IOStream.h. * examples/Logger/client/logging_app.cpp (main), performance-tests/Misc/test_naming.cpp (*): replaced sprintf with ACE_OS::sprintf. Thanks to Thilo Kielmann for reporting these. Tue Apr 29 20:03:38 1997 * apps/JAWS/stress_testing/http_tester.cpp : Removed usage of pow (), and changed method of calculating throughput/latency to use straight multiplication instead of pow (). Updated Makefile to not link -lm. Tue Apr 29 19:57:52 1997 * config-win32-common.h (ACE_HAS_TEMPLATE_SPECIALIZATION): Win32 supports this option. Added to config file. * ace: Removed tracing for the following to make things work with tracing on: ACE::timestamp ACE_FIFO_Send_Msg::send ACE_SPIPE_Stream::send ACE_Sig_Guard::ACE_Sig_Guard ACE_Sig_Guard::~ACE_Sig_Guard * netsvcs/servers/main.cpp (main): Added special code for Win32 such that only SIGINT is being registered with the Signal Handler. SIGQUIT is not supported on Win32. * netsvcs/lib/Token_Handler.cpp (init): Removed the registration of the Acceptor for SIGINTs. * netsvcs/lib/TS_Server_Handler.cpp (init): Same as above. * netsvcs/lib/Client_Logging_Handler.cpp (open): Removed the registration of SIGPIPE for Win32. Win32 does not support SIGPIPE. * tests/Process_Strategy_Test.cpp (server): The new thread must become owner before it can call Reactor::handle_events. Also fixed #define typo. * ace/OS.cpp (socket_fini): Remove the ACE error message as the IO Stream objects are already gone by this point in the program. * examples/Registry/Registry.mak: Replaced the old makefiles with this one. Also added _AFXDLL as a preprocessor define, forcing the correct inclusion of header files that give a consistent definition of HKEY. This is a hack till we have a better solution. * ace/Event_Handler: Removed the old Proactor callback methods. Tue Apr 29 17:39:40 1997 Douglas C. Schmidt * ace/config-mvs.h: Added #define ACE_LACKS_LINEBUFFERED_STREAMBUF for MVS. Thanks to Chuck Gehr for reporting this. * ace: Commented out ACE_TRACE calls in constructors in several ACE classes in order to avoid problems with circular initialization dependencies related to mutexes that are breaking code on WinNT when ACE_NTRACE is set to 0. Thanks to Lothar Hermann for reporting these. * ace/Reactor.cpp: It looks as if Windows NT isn't returning the number of bytes requested by a WinSock recv() used in the ACE_Reactor::notify() in some situations. This is causing problems for test programs under heavy load. The fix appears to be to add an additional ACE::recv() to obtain the remaining bytes. Thanks to Karlheinz for reporting this and to Irfan for helping to fix it. * ace/OS.i: Fixed a very subtle bug with ACE_OS::cond_wait() and ACE_OS::cond_signal() that only manifests itself when ACE_HAS_SIGNAL_OBJECT_AND_WAIT is enabled (which isn't the default). The problem stemmed from the fact that we were assuming that if we used condition variables it implied that the external mutex had USYNC_PROCESS scope. In fact, the external mutexes typically have USYNC_THREAD scope, so SignalObjectAndWait() was hanging indefinitely. Fortunately, the fix was easy -- just add a run-time check for the type of the external mutex and take the appropriate action. Thanks to Irfan for noticing this. * tests/Reader_Writer_Test.cpp: Added a parse_args() function that allows us to override the default number of reader/writer threads + the number of iterations. * ace/OS: Added patches for Digital UNIX to handle the getpwnam_r() name. Thanks to Thilo Kielmann for these patches. Tue Apr 29 14:27:19 1997 * OS.h: Added ACE_HAS_SVC_DLL. If you write a library and want it to use ACE_Svc_Export, this will cause those macros to build dlls. If you want your ACE service to be a static library, comment out this line. As far as I know, the only reason to have a library be an ACE "service" is to leverage the ACE_Svc_Export macros. It's just as easy to define your own export macros. Tue Apr 29 07:25:25 1997 David L. Levine * apps/JAWS/server/HTTP_Request.h (HTTP_Request): added destructor declaration. * apps/JAWS/server/Parse_Headers.cpp (parse_header_line): assign local "value" to value_ field of map_[header]. * apps/JAWS/server/HTTP_Request.cpp (HTTP_fix_path): commented this static function out because it's not used, and g++ warns about that. * apps/JAWS: added CVS header to all .h, .i, and .cpp files. Tue Apr 29 00:33:46 1997 * examples/Reactor/Misc/notification.cpp: Add this test to the Win32 makefile. * ace: Removed config-win32-msvc2.0.h, config-win32-msvc4.0.h config-win32-msvc4.x.h, and config-winnt-4.0-msvc.h from the repository. These files have been replaced by config-win32.h and config-win32-common.h. * IOStream_Test.cpp (main): Added return 0 at the end of main(). * examples/Reactor/Proactor/test_proactor.mak: Added wsock32.lib to the link line. I am not sure why we have to do this again since ace.lib already includes it. Without this library in the link line, GetAcceptExSockaddr is not defined. Go figure! * apps/JAWS/server/jaws.mak: Same as above. * ace/ace.{mak,mdp}: Fixed the generation of the release version of ace.dll such that wsock32.lib is automatically included. Tue Apr 29 00:16:27 1997 James C Hu * JAWS: Changes to support CGI scripts Changed the following files -- HTTP_Handler.cpp HTTP_Handler.h HTTP_Helpers.cpp HTTP_Helpers.h HTTP_Request.cpp HTTP_Request.h IO.cpp IO.h Added the following files -- HTTP_Response.cpp HTTP_Response.h Parse_Headers.cpp Parse_Headers.h Removed the file -- JXH_String.h * JAWS/stress_testing: Changed the Makefile to link in the math library (-lm). * ace/OS.h and ace/OS.i: Added support for memmove(). Mon Apr 28 21:35:35 1997 Douglas C. Schmidt * ace/IOStream.h: Added a new macro called ACE_LACKS_IOSTREAM_SETGET, which works around bugs with SGI C++ on IRIX 6.2. Thanks to Torbjorn Lindgren for reporting this. * ace/Timer_List_T.h: Replaced the use of ITERATOR with ACE_Timer_Queue_Iterator_T to work around problems with SGI C++. Thanks to Torbjorn Lindgren for reporting this. * ace/Timer_List_T.cpp: Removed the use of NODE * and replaced it with ACE_Timer_Node_T in order to work around bugs with certain C++ compilers (i.e., SGI). Thanks to Torbjorn Lindgren for reporting this. * tests/Conn_Test.cpp: Removed some extraneous template specializations. Thanks to Nanbor Wang for reporting these. * apps/JAWS/client/Blob.cpp: Rearranged some of the template specializations in the hope of fixing a linker problem with SunC++ 4.2. * ace/config-irix-6.2*.h. It appears that SGI IRIX 6.2 supports pread() and pwrite() so I enabled the ACE_HAS_P_READ_WRITE macro in the IRIX 6.2 config file. * ace/OS.cpp: Implemented ACE_OS::pread() and ACE_OS::pwrite() for systems that lack this feature. The implementation uses the new ACE_Thread_Mutex monitor lock in order to ensure atomicity between the lseek() and the read()/write(). * ace/OS.cpp: Finally broke down and added a ACE_Thread_Mutex monitor lock to the ACE_OS implementation file. This is useful for situations where we need to serialize certain ACE_OS emulation calls (e.g., ACE_OS::{pwrite,pread}). Mon Apr 28 15:42:48 1997 David L. Levine * apps/JAWS/client/blobby.cpp: updated template specializations. * apps/JAWS/stress_testing/global.h: removed #includes of system headers because ace/OS.h takes care of them. They were causing warnings with g++ (because they were #included before OS.h). * examples/ASX/UPIPE_Event_Server/Supplier_Router.cpp: fixed typos in template specializations. * tests/Conn_Test.cpp,Message_{Block,Queue}_Test.cpp, Process_Strategy_Test.cpp: fixed template specializations for platforms without threads. Thanks to Nanbor Wang for pointing out this problem. * ace/Connector.h: use ACE_SYNCH_RW_MUTEX in Map typedefs instead of old ACE_RW_Mutex (which should have been ACE_Thread_RW_Mutex) and ACE_Null_Mutex (depending on whether the platform has threads). * ace/Service_Record.cpp: added ACE_NULL_SYNCH template specializations with threads, because they're still needed even with threads. This way, individual programs don't have to specialize these. * ace/Task.cpp: added ACE_TSS and ACE_TSS template specializations, if the platform has threads and TSS. This way, individual programs don't have to specialize them. * apps/Gateway/Gateway/Event_Channel.cpp, Proxy_Handler{,_Connector}.cpp,apps/JAWS/server/HTTP_Server.cpp, examples/ASX/Event_Server/Transceiver/transceiver.cpp, examples/ASX/UPIPE_Event_Server/Consumer_Router.cpp, examples/Connection/blocking/SPIPE-connector.cpp, examples/Connection/misc/{Connection_Handler,test_upipe}.cpp, examples/Connection/non_blocking/test_*.cpp, examples/IOStream/server/iostream_server.cpp, examples/Logger/Acceptor-server/server_loggerd.cpp, examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp, netsvcs/lib/Client_Logging_Handler.cpp, netsvcs/lib/TS_{Clerk,Server}_Handler.cpp: removed template instantiations that are now in ace/Service_Record.cpp and ace/Task.cpp. This should help on platforms without threads. * examples/ASX/UPIPE_Event_Server/Supplier_Router.cpp: fixed typos in template specializations. * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: protected the ACE_*Guard template instantiations with #ifdef ACE_HAS_THREADS. * examples/ASX/Event_Server/Transceiver/transceiver.cpp: protected the ACE_*Guard template instantiations with #ifdef ACE_HAS_THREADS. * apps/JAWS/stress_testing/benchd.cpp (serve): added return -1 if the strcmp () fails so that the function always returns a value. Mon Apr 28 18:53:58 1997 Darrell Brunsch * ace/OS.h: Added ACE_DEFAULT_TIMER_WHEEL_SIZE and ACE_DEFAULT_TIMER_WHEEL_RESOLUTION constants. * ace/Timer_Wheel_T.h: switched to use these constants * tests/Timer_Queue_Test.cpp: switched to use these constants * ace/Timer_Wheel: added a new strategy for Timer Queues, one based on a hash table of ordered lists. These files were added: - ace/Timer_Wheel.h - ace/Timer_Wheel_T.h - ace/Timer_Wheel_T.cpp These files were also changed to accomodate Timer Wheel - ace/Timer_Queue.cpp - ace/Timer_Queue_T.h - ace/Timer_Queue_T.cpp - tests/Timer_Queue_Test.cpp Mon Apr 28 17:32:04 1997 Chris Cleeland * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: Added template specializations. * examples/ASX/Event_Server/Transceiver/transceiver.cpp: Added template specializations. * ace/OS.cpp (thr_create): Hopefully resolved tension btw. priority determination algorithms for IRIX, LinuxThreads, and DEC UNIX 4.0. Thanks to Thilo for information that lead to this. Mon Apr 28 00:25:17 1997 * apps/JAWS/client: Removed ACE_Export macro from class declarations. Fixed buffer size bug in ACE_Blob_Reader::receive_reply (). Sun Apr 27 22:22:14 1997 * ace/Proactor: The Proactor can now be registered with ReactorEx and both of them can be run from ReactorEx's event loop. Added a flag to Proactor's constructor that indicates whether the Proactor will be used in conjunction with ReactorEx event loop. Only if this flag is set will the event in the Proactor be used by the Asynch IO components. This will help with performance. * examples/Reactor/Proactor/test_multiple_loops.cpp: Added a new test that shows the integration of the event loops of Proactor and ReactorEx. * ace/Asynch_IO: Added an ACE_EVENT parameter to the constructors of classes that inherit from the OVERLAPPED structure. This way the Proactor's event_ can be set in the OVERLAPPED structure. Also changed the open methods on the Asynch IO classes to take a Proactor as an extra parameter. Changed ACE_Handler's handle_timeout() to handle_time_out() in ACE_Handler. This is temporary till we decide on the argument about mixing the interface of ACE_Event_Handler and ACE_Handler. This change allows user to inherit from ACE_Handler and ACE_Event_Handler and use the different handle_timeout() method, one of which returns void and the other return an int. * examples/Reactor/Proactor/test_timeout.cpp: This file got affected by the above change. Sun Apr 27 17:44:28 1997 Douglas C. Schmidt * ace/OS.h: Added a new #define called ACE_DEFAULT_HTTP_SERVER_PORT. Naturally, this defaults to 80... * apps/JAWS/client/blobby.cpp: Cleaned up the blobby example so that it conforms more closely to the ACE style guide. * examples/IPC_SAP/SOCK_SAP/CPP-in{server,client}.cpp: Took out the VxWorks-specific #ifdefs. I believe this is fixed in ACE_OS now. If not, the burden of proof is on the VxWorks testers to prove me wrong ;-). * ace/Synch_T.h: Added a new macro ACE_SYNCH_RW_MUTEX to complement the existing ACE_SYNCH_MUTEX and ACE_SYNCH_CONDITION macros. This will clean up lots of code in various test programs. * ace/Synch_T.h: Added two new macros, ACE_SYNCH_MUTEX and ACE_SYNCH_CONDITION. These default to ACE_MT_SYNCH::MUTEX and ACE_MT_SYNCH::MUTEX if template typedefs are supported and ACE_HAS_THREADS is enabled. If template typedefs *aren't* supported but ACE_HAS_THREADS is enabled these macros turn into ACE_Thread_Mutex and ACE_Thread_Condition. Finally, if ACE_HAS_THREADS is disabled these macros turn into ACE_Null_Mutex and ACE_Null_Condition. These macros make it possible to write code that is more portable across platforms and configurations. Thanks to Carlos O'Ryan for this suggestion. * ace/OS.h: Replaced all uses of ACE_SYNCH_MUTEX and ACE_SYNCH_CONDITION with ACE_SYNCH_MUTEX_T and ACE_SYNCH_CONDITION_T since (1) this usage relates to templates and (2) it frees up the namespace for the new ACE_SYNCH_MUTEX and ACE_SYNCH_CONDITION macros. * ace/Timer_Queue.cpp: Added yet more template specializations for the benefit of GCC (ugh). * ace/Timer_Wheel_T.cpp: Had to revise things just a bit to compile with GCC and it's lame template mechanism. This required changing NODE * to ACE_Timer_Node_T * in several method definitions. * apps/JAWS/server/HTTP_Server.h: Changed the use of ACE_WIN32 to ACE_HAS_THREAD_SAFE_ACCEPT since this is a more precise way to determine if the platform allows multiple threads to call accept() on the same port. If other platforms support this feature please make sure to add it to their config*.h files. * ace/config-win32-common.h: Defined ACE_HAS_THREAD_SAFE_ACCEPT, since Win32 allows multiple threads to call accept() on the same port. * examples/ASX/UPIPE_Event_Server/Supplier_Router.cpp: The mutex should be ACE_RW_Mutex, not ACE_Null_Mutex... Sun Apr 27 18:13:24 1997 Irfan Pyarali * ace/Proactor.h: Added Timer_Wheel support. Sun Apr 27 18:13:24 1997 Sumedh Mungee * apps/JAWS/client: Removed blobby.h, and replaced it with blobby_options.{h,cpp}. * apps/JAWS/stress-testing: Removed unused argument warnings etc. Sun Apr 27 07:41:44 1997 David L. Levine * ace/Timer_Queue.cpp: added #includes for template specializations, and removed some unused specializations. * ace/Timer_Wheel_T.cpp: added newline at end of file. * ace/Timer_Wheel_T.cpp (ACE_Timer_Wheel_T ctor): reordered initializers to match declaration order. * ace/Log_Msg.cpp (log): added support for indenting output according to the current nesting level by adding a new format specifier, I, which indents the output according to the current trace_depth_. If a width is also specified it is taken as multiplier (so that the indentation is n*trace_depth_). Thanks to Matthias Kerkhoff for providing the code for this feature! * examples/Reactor/Misc/test_timer_queue.cpp: fixed typos in #includes, and added #include of ace/Timer_Heap.h. Sat Apr 26 17:19:56 1997 Irfan Pyarali * ace/Timer_Queue.cpp: The correct Timer_Queue.cpp file was not checked in. Also the necessary #include was missing. * ace/Proactor.h: Proactor need all three Timer include files. * ace/ace.{mdp,mak}: Updated for changes to Timer files. * ace: Updated the following files to include /**/ before an include file directive: OS.h, config-win32-common.h, bstring.h. Thanks to Matthias Kerkhoff for reporting this. Sat Apr 26 13:41:15 1997 Douglas C. Schmidt * ace/config-sco-5.0.0-mit-pthread.h: Added ACE_LACKS_PTHREAD_CANCEL. Thanks to Arturo Montes for reporting this. * ace: Came up with a scheme that allowed us to remove the ace/Timers.{h,i,cpp} files by adding ACE_Timer_{Queue,Heap,List}_T.{h,i,cpp} files instead. Thus, no existing code should break. Fri Apr 25 17:17:06 1997 Chris Cleeland * ace/OS.cpp (thr_create): Fixed the fix from Thilo so that it compiled properly on Linux. Hopefully I didn't break his, and I should have detected the problem earlier. Mea culpa. Fri Apr 25 12:45:23 1997 Douglas C. Schmidt * ace/OS.h: Added a new macro called ACE_HAS_SIG_MACROS for the case where the frigging OS defines things like sigismember and sigfillset as macros (ugh). * ace/FILE_IO.h: Removed a trailing default initializer from the send() method since it was ambiguous. Thanks to Carlos O'Ryan for reporting this bug. * ace/OS.i (select): Unfortunately the (operator timeval*) defined for ACE_Time_Value was not used in ACE_OS::select (int width, fd_set *rfds, fd_set *wfds, fd_set *efds, const ACE_Time_Value *timeout) because the operator cannot be applied for a ACE_Time_Value*. Therefore, I fixed this as follows: ACE_SOCKCALL_RETURN (::select (width, (ACE_FD_SET_TYPE *) rfds, (ACE_FD_SET_TYPE *) wfds, (ACE_FD_SET_TYPE *) efds, timeout == 0 ? 0 : (timeval *) *timeout) , int, -1); Thanks to Carlos O'Ryan for reporting this bug. * ace: Applied a slew of patches from Carlos O'Ryan in order to get ACE to compile on HP/UX 10.x with the aCC compiler. * ace/Shared_Memory_MM: Export the filename in ACE_Shared_Memory_MM class in order to aid debugging. Thanks to Ashish Singhai for reporting this. Fri Apr 25 14:58:38 1997 Irfan Pyarali * ace/Timers: Updated the following files to make it compile on g++. The following files were updated: Proactor.cpp Timer_Heap.cpp Timer_List.cpp Timer_Queue.cpp Timers.cpp Thu Apr 24 21:13:51 1997 * ace/Timer_Queue: Decoupled the Timer Queue from ACE_Event_Handler and the callback routines in the handler (handle_timeout and handle_close). The new Timer Queue is parameterized by the type of data to store and a FUNCTOR on which methods are invoked by the Timer Queue when timeouts and cancellations occur. No changes occured to the algorithms of the different implementations of the Timer Queues (Timer List and Timer Heap). Timer Queues, Timer List, and Timer Heap were all renamed as _T. However, typedef were added such that there is now an ACE_Timer_Queue, ACE_Timer_Heap, and ACE_Timer_List, each being an instantiation of the respective template classes. The instantiation is done with ACE_Event_Handler as the type of data to be stored in Timer Queue and ACE_Event_Handler_Handle_Timeout_Upcall as the FUNCTOR that does the appropriate upcall to ACE_Event_Handler. Due to these typedefs, 99.9% of existing code should not break. However, the following two will cause problems: (a) Forward declarations of Timer_Queue will not work! This is because Timer_Queue is now a typedef and not a class. (b) #include "ace/Timer_Queue.h" will not be enough to get the ACE_Timer_Queue typedef. The new typedefs are in a new file called Timers.h. This file also has typedefs for ACE_Timer_Heap and ACE_Timer_List. Currently Proactor is the only class that uses a different instantiation of the Timer Queue class. Proactor's Timer Queue class is instantiated with ACE_Handler as the type of data to be stored in Timer Queue and ACE_Proactor_Handle_Timeout_Upcall as the FUNCTOR that does the appropriate posting to the Proactor's completion port. The Upcall Strategy is not needed any more cause it is replaced by the FUNCTORs. Thus this is removed. Small modifications were made to the following files because of the changes to Timer_Queue. - examples/Reactor/Misc/test_timer_queue.cpp - examples/Reactor/Proactor/test_timeout.cpp - tests/Timer_Queue_Test.cpp - ace/Makefile (both UNIX and Win32) - ace/Connector.h - ace/Reactor.h - ace/ReactorEx.h - ace/Proactor.h * ace/Proactor: Proactor now uses the new timer queues. Proactor's Timer Queue class is instantiated with ACE_Handler as the type of data to be stored in Timer Queue and ACE_Proactor_Handle_Timeout_Upcall as the FUNCTOR that does the appropriate posting to the Proactor's completion port. This will help reduce the overhead of creating new act for each timer. This also enables the cancellation of entire ACE_Handlers. * examples/Reactor/Misc: Added Win32 makefiles. * ace/Shared_Memory_MM.i: Fixed typo. * ace/SOCK_Connector.cpp: Fixed typo. Thu Apr 24 13:56:28 1997 Douglas C. Schmidt * ace/SOCK_Dgram.cpp: Added support for FreeBSD (i.e., BSD 4.4) features for passing file descriptors between processes. Thanks to Nanbor Wang for reporting this. * ace/LSOCK_Stream.cpp: Added support for FreeBSD (i.e., BSD 4.4) features for passing file descriptors between processes. Thanks to Nanbor Wang for reporting this. * ace/LSOCK.cpp: Added support for FreeBSD (i.e., BSD 4.4) features for passing file descriptors between processes. Thanks to Nanbor Wang for reporting this. * ace/SOCK_Connector.cpp (complete): There's a bug in WinNT that causes non-blocking connects to fail. The workaround is to sleep for 1 millisecond. Thanks to Steve Huston for reporting this. * ace/Connector.cpp (handle_output): There's a bug in WinNT that causes non-blocking connects to fail. The workaround is to sleep for 1 millisecond. Thanks to Steve Huston for reporting this. * tests/Conn_Test.cpp: Changed from operator != to operator == to be consistent with what is required by the ACE_Hash_Map_Manager. * ace/Hash_Map_Manager: Factored out the equality comparison into an equal() method in order to facilitate template specialization. In addition, rather than using the != operator we now default to using the operator== operator and negating the result. This is consistent with the behavior of the ACE_Map_Manager. * ace/Map_Manager: Factored out the equality comparison into an equal() method in order to facilitate template specialization. * ace/OS.i: Added a new #ifdef called ACE_LACKS_PTHREAD_CANCEL. I'm not sure which platforms should set this, but it fixes a bug with ACE_OS::thr_cancel(). Thanks to Eric Dean Russell for reporting this. * tests/Process_Strategy_Test.cpp (handle_input): We were comparing EOF to a char, which gets complaints on platforms where char is unsigned by default. I added a cast of EOF to char to fix this. Thanks to Amos Shapira for reporting this. * apps/JAWS/server/HTTP_Helpers.cpp (instance): Changed the return type from const char * to const char **. Thanks to Amos Shapira for reporting this. * ace/OS.i (getpwnam_r): Added a missing #else. Thanks to Amos Shapira for reporting this. * ace/Timer_Heap: Made many minor enhancements to ACE_Timer_Heap in an effort to figure out why we're getting memory leaks. Thu Apr 24 09:33:53 1997 David L. Levine * Makefile: modified the TIMESTAMP macro to update the third component, if there is one, of the version number in the VERSION file. This assumes that alpha/beta releases are numbered with three components, and that final releases are not. So, if the version number is, e.g., 4.2, it will not be modified because it is assumed to be for a final release. Manual switching between alpha/beta and final release "modes" is therefore still required. * ace/Timer_Heap.cpp (copy): added cast of max_size_ to int to avoid signed/unsigned comparison. * ace/config-sunos5.4-g++.h: removed ACE_HAS_CONSISTENT_SIGNAL_PROTOTYPES because it caused compile warnings about conversion from `(int)' to `(...)' at Signal.i:113. (And the other sunos5.4 config files don't have it.) Thanks to Joey Zhu for reporting this. * tests/Timer_Queue_Test.cpp (main): added delete of timer_ids array to avoid memory leak. Wed Apr 23 22:56:57 1997 Sumedh Mungee * apps/JAWS/client/*: Fixed warnings due to size_t * apps/JAWS/client/Blob_Handler: Fixed error by passing pointer to base class ACE_Blob_Handler instead of pointing to ACE_Blob_Reader, in call to connect Wed Apr 23 20:57:35 1997 James C Hu * ace/OS.i and ace/OS.h: added methods for getpwnam and getpwnam_r, with hooks for NT. * ace/config-irix6.2.*: added ACE_LACKS_PWD_REENTRANT_FUNCTIONS. Wed Apr 23 14:27:48 1997 David L. Levine * ace/Timer_Queue.cpp (ACE_Timer_Queue ctor): reordered initializers to match declaration order. * tests/Process_Strategy_Test.cpp: added ACE_Singleton template specialization. In function client (), null terminated "buf" before call to ACE_OS::strrchr () to avoid uninitialized memory read. Also, fixed typo in test name (argument to ACE_START_TEST). * examples/Service_Configurator/Misc/Timer_Service.cpp (init): changed type of loop index to int to avoid signed/unsigned comparison, and initialized "interval" so that it has a value even if one isn't specified on the command line. Wed Apr 23 10:52:45 1997 Chris Cleeland * ace/OS.cpp (thr_create): Removed errant preprocessor conditional for determining the scheduling priority. Thanks to Thilo Kielmann for reporting this. Wed Apr 23 09:06:52 1997 Douglas C. Schmidt * tests/Process_Strategy_Test.cpp: Finished updating this program so that it is an automated test. * ace/Acceptor.h: Moved get_handle() into the public portion of the Acceptor. * include/makeinclude/platform_irix6.2_sgic++.GNU (SOBUILD): There was an extra @ in $@@. Thanks to Amos Shapira for reporting this. * apps/JAWS/client/Blob[_Handler].cpp: Added casts for free ((void *) filename_);. Thanks to Amos Shapira for reporting this. * apps/JAWS/server/HTTP_Helpers.h (class HTTP_Status_Code): Removed an extraneous const * from the definition of instance(). Thanks to Amos Shapira for reporting this. Wed Apr 23 03:15:11 1997 James C Hu * apps/JAWS/server/README: Updated to add some clarity and more useful information. Tue Apr 22 20:17:00 1997 Douglas C. Schmidt * ace/Synch.cpp: Added a new method called open() to ACE_File_Lock so that we don't have to initialize it solely in the constructor. * tests/Process_Strategy_Test.cpp: Added new test code that exercises the ACE_Process_Strategy, ACE_Thread_Strategy, and ACE_Reactive_Strategy classes. * ace/Strategies_T: Added a new class called ACE_Reactive_Strategy, which inherits from ACE_Concurrency_Strategy and registers new Svc_Handlers with the Reactor. * ace/Strategies_T.cpp (ACE_Thread_Strategy): Added a check for failed open() methods and call ACE_ERROR. * tests/Map_Manager_Test.cpp: Added a template specialization for the ACE_Hash_Map_Manager::hash() method, which is enabled if the compiler supports template specializations. * ace/Hash_Map_Manager.h (pool): Moved the ext_id.hash() call into a separate method so that we can perform template specialization of it more easily. * ace/README: Added a new #define called ACE_HAS_TEMPLATE_SPECIALIZATION so that we can work around funky compilers that don't support this advanced template feature. * ace: Added Nanbor Wang's port to FreeBSD. The port is done at FreeBSD 3.0-current as of 2/9/97, which is the latest stable system before Lite2 merge. Since the merge is current under testing and changes are introduced in a daily basis, I don't recommend using -current after the date. You can specified the date in your "supfile", run CVSup to get the entire source tree and do a 'make world' to update (or reverse) your system. Pthread library is provided by John Birrell. There is a bug fix at mid April so you may want to CVSup the latest libc_r library and re-make the pthreaded library. A shared library must be name as lib.so. (e.g. libACE.4.1.0). I would recommend adding a post-compile hook in the Makefile so we FreeBSDers can rename the shared library to it's proper name with correct major and minor version number attached. (which is a trick BSD library makefiles use.) * examples/OS/Process/process.cpp (main): Replaced the use of "/bin/cat" with "cat" since we are now using execvp(). Thanks to Nanbor Wang for reporting this. * ace/Process.cpp (start): Changed the use of execv() to execvp() in order to avoid having to pass in the full pathname. * ace/OS.i (sigwait): Added an #ifdef for FreeBSD so that we return ACE_NOTSUP_RETURN(-1) for ACE_OS::sigwait(). Thanks to Nanbor Wang for reporting this. Tue Apr 22 17:46:30 1997 * Process.cpp (start): We must pass in 0 instead of "" to CreateProcess for the current working directory. Tue Apr 22 01:38:14 1997 * ace/Timer_Queue: Added ACE_Upcall_Strategy as a parameter to the constructor. will call upcall> if is not 0. Else it will call on the . Thus ACE_Upcall_Strategy becomes a vehicle for extending the behavior of ACE_Timer_Queue wrt the upcall (callback) *without subclassing*. Hence, it's an example of the Bridge/Strategy patterns. This also affected ACE_Timer_List and ACE_Timer_Heap * ace/Strategies: Added ACE_Upcall_Strategy. * ace/Proactor: Added timing support to the calls. * ace/Asynch_IO: ACE_Handler now supports handle_timeout. * ace/Proactor: Added timer support for the new Proactor. This new scheme allows any of the threads in the "thread pool" waiting on the completion port of the Proactor to execute the callback routine of the handler. The implementation included adding ACE_Proactor_Timer_Handler class that has a thread that will wait on the earliest time in a timer queue and an event. When a timer expires, the thread will post a completion event on the port and go back to waiting on the timer queue and event. If the event is signaled, the thread will refresh the time it is currently waiting on (in case the earliest time has changed). The ACE_Proactor::Asynch_Timer class is posted to the completion port when a timer expires. When the method of this object is called, the 's handle_timeout method will be called. * examples/Reactor/Proactor/test_timeout: This example illustrates the new timer features in the Proactor * examples/Reactor/Proactor/test_proactor.{mdp,mak}: Added new example. Mon Apr 21 18:14:32 1997 Irfan Pyarali * ace/config-win32-common.h: Added checks around _AFXDLL before defining it. Thanks to Bruce Meyer for pointing this out. Mon Apr 21 11:31:16 1997 Chris Cleeland * examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp: Removed some unnecessary explicit template instantiations. * examples/Threads/barrier1.cpp (main): Explicitly converted n_threads to int. Sun Apr 20 23:08:37 1997 Irfan Pyarali * ace/{Local,Remote}_Tokens.h: Added a private declarations of the copy constructor and assignment operator for classes that inherit from ACE_TSS. This is necessary since the compiler will auto generate these two operations that will end up using the non-existent copy constructor and assignment operator from the TSS class and cause linker errors. Sun Apr 20 20:47:34 1997 Sumedh Mungee * apps/JAWS/client: Reworked the ACE_Blob* classes to work with the new Connector behavior. Added README for this directory. Added comments. * apps/JAWS/stress-testing: Added README file Sun Apr 20 13:11:25 1997 Douglas C. Schmidt * apps/Makefile: By default, we now compile JAWS along with the rest of ACE. I've also added some README files that explain what JAWS is all about. * examples/Service_Configurator/Misc/Timer_Service: Improved the Timer_Service test so that it makes more sense and is better documented. Sat Apr 19 11:56:35 1997 Douglas C. Schmidt * include/makeinclude: Removed the platform_irix6.2_sgiCC.GNU from the release. Thanks to Torbjorn Lindgren for these fixes. * include/makeinclude/platform_irix6.2_sgic++.GNU: Updated the SGI C++ platform config file. Thanks to Torbjorn Lindgren for these fixes. * ace/Log_Msg.cpp (log_hexdump): The char * arguments should be const char *'s. Thanks to Matthias Kerkhoff for reporting this. Sat Apr 19 18:52:44 1997 David L. Levine * (format_hexdump): changed type of first arg to const char * for compatibility with Log_Msg::log_hexdump (). Thu Apr 17 08:25:06 1997 Douglas C. Schmidt * ace/Memory_Pool.h: Fixed a couple of typos in Memory_Pool classes. Thanks to Neil B. Cohen for reporting this. * netsvcs/lib/Name_Handler.h: Arrgh, there was still one more missing #include that I forgot to move into the *.h file. Thanks to David Levine for noticing this. * ace/Synch.cpp (wait): There was a bug in ACE_Condition::wait(MUTEX& mutex, const ACE_Time_Value *abstime.) Basically when abstime is zero, it ignores the parameter "mutex" that has been passed to it and instead goes on to call "ACE_Condition::wait()" which uses "this->mutex_" as the mutex to be released and not the mutex that the caller has given. The fix is to change the call "this->wait()" in the if-clause to: return ACE_OS::cond_wait (&this->cond_, &mutex_.lock_); Thanks to Ashish Singhai for reporting this. Thu Apr 17 16:33:21 1997 David L. Levine * ace/Memory_Pool.cpp: fixed typos in ACE_MMAP_Memory_Pool_Options constructor declaration and initializer list. In init_acquire, added cast of minimum_bytes_ to size_t to avoid signed/unsigned comparison. * include/makeinclude/{platform*,wrapper_macros}.GNU: moved -g out of wrapper_macros.GNU and into each platform file so that -gstabs can be used on SCO. Thanks to Ganesh Pai for reporting that problem. (The real change was getting rid of the CFLAGS += DCFLAGS default. We could have left DCFLAGS=-g in wrapper_macros.GNU and overridden for SCO. But the way I changed things, the C/CFLAGS pieces are together in each platform file, so they're easier to find.) Wed Apr 16 17:05:55 1997 Douglas C. Schmidt * ace/Memory_Pool.cpp (acquire): Added code to enable a minimum bytes field with the Shared_Memory_Pool. Thanks to Fred LaBar for these enhancements. * tests/Process_Strategy_Test.cpp: Only compile this test if ACE_LACKS_EXEC is *not* defined since ACE_Process_Strategy requires fork(). Thanks to Irfan for pointing this out! * netsvcs/lib: Fixed a couple o' typos that had escaped detection last night. Thanks to David Levine for reporting this. * ace/Synch[_T].h: removed the use of {} rather than ; for the private copy constructors and assignment operators. Hopefully this won't break code on older C++ compilers. Thanks to Berni Merkle for suggesting this. * Added a whole slew of minor fixes for unused variables in the tests and examples. Thanks to Torbjorn Lindgren for reporing these. * ace/Handle_Set.cpp (ACE_Handle_Set_Iterator): The order of the clause this->handles_.mask_.fds_bits[this->index_] == 0 && this->num_ < ACE_Handle_Set::MAXSIZE was backwards. It should be: this->index_ < ACE_Handle_Set::NUM_WORDS && this->handles_.mask_.fds_bits[this->index_] == 0 Thanks to Michael Newton for reporting this. Wed Apr 16 21:34:53 1997 David L. Levine * tests/Process_Strategy_Test.cpp: added template specializations. Wed Apr 16 15:46:58 1997 * tests/Process_Strategy_Test: Added test to batch files and MSVC++ Makefiles. * tests/Process_Strategy_Test.cpp (open): Added UNICODE support. * ace/OS.h: Added SIGCHLD to Win32 section. * ace/config-win32-common.h: UNICODE should not be automatically defined if ACE_HAS_UNICODE is defined. ACE_HAS_UNICODE signifies that the OS has UNICODE support. It does not mean that your code must be UNICODE. UNICODE must be defined at the project level. Wed Apr 16 16:55:47 1997 David L. Levine * ace/SString.{h,cpp}: Modified CString to not allocate 1 byte for a 0 length string. Instead, set the internal representation to the address of static class character null_string_. Wed Apr 16 11:47:35 1997 Chris Cleeland * ace/Map_Manager.cpp (free_search_structure): Added the loop variable back in that must have been inadvertently deleted in the previous entry. Wed Apr 16 09:35:39 1997 David L. Levine * ace/Map_Manager.cpp (free_search_structure): changed type of loop index to size_t to avoid signed/unsigned mismatch. Wed Apr 16 04:07:50 1997 Douglas C. Schmidt * ace/Strategies_T: Widened the constructor interface for ACE_Process_Strategy based on the feedback I got from implementing the Process_Strategy_Test.cpp program. * tests/Process_Strategy_Test.cpp: Added an interesting new test that illustrates the use of the ACE_Process_Strategy and the ACE_File_Lock. To exercise this program, you can telnet to it and type "read" and "inc" to query and change the count of the numbers in the file, respectively. * ace/Connector.cpp (create_AST): I fixed a couple of things in Connector.cpp: - In create_AST, it needs to save and restore errno, else it gets wiped on Win32 and other platforms. - On Win32 when a non-blocking connect completes and handle_output is called, it tries to get the peer address. If done too quickly, it fails. I put in a Sleep(0) call. I think this is not a great solution, but I don't have a better one yet. Thanks to Steve Huston for fixing these bugs. Tue Apr 15 17:09:33 1997 Douglas C. Schmidt * ace/SOCK_Stream.cpp (close): Removed the call to close_writer() on UNIX since that doesn't do the correct thing in many cases since it causes a protocol transmission which isn't what we want if we're using fork(). * ace/Strategies_T.cpp (activate_svc_handler): Added a call to svc_handler->destroy() in the parent since we don't need it and we're leaking descriptors and memory otherwise... Thanks to Kevin Boyle for reporting this. * ace/OS.i (thr_sigsetmask): Replaced the use of PTHREADS_1003_DOT_1C with ACE_HAS_PTHREAD_SIGMASK. Thanks to Arturo Montes for suggesting this. * ace: Changed all uses of ACE_HAS_PTHREADS_XAVIER to ACE_HAS_PTHREAD_SIGMASK, which is more descriptive. Thanks to Arturo Montes for suggesting this. * ace/config-aix-4.2.x.h: Added #define ACE_LACKS_RWLOCK_T to make things compile with AIX 4.2. Thanks to Jeremy Buch for reporting this. * ace/XtReactor.cpp (register_handler_i): Added "[]" to delete this->ids_ since it is an array. Thanks to Jean-Marc Strauss for reporting this. * netsvcs/lib: Moved all the class definitions into the *.h files to avoid complaints from the IBM C++ compiler. * ace/OS.h: Added a #define for WNOHANG since this is missing on NT. Thanks to Brian Mendel for reporting this. * examples/Connection/non_blocking/test_sock_connector.cpp: Added a typedef for ACE_RW_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. * examples/Connection/non_blocking/test_tli_connector.cpp: Added a typedef for ACE_RW_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. * examples/Connection/misc/test_upipe.cpp: Added a typedef for ACE_RW_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. * performance-tests/Synch-Benchmarks/Options.cpp: Added a #ifdef for ACE_Thread_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. * examples/ASX/Event_Server/Transceiver/transceiver.cpp: Added a typedef for ACE_RW_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. * examples/ASX/UPIPE_Event_Server/Consumer_Router.cpp: Added a typedef for ACE_RW_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. * examples/ASX/Event_Server/Event_Server/Options.cpp (print_results): Although rusage struct is defined on SCO, there is no getrusage(), rusage is used only by wait() etc. internally. Therefore, we had to move some #ifdefs around. Thanks to Ganesh Pai for reporting this. * apps/Gateway/Gateway/Proxy_Handler_Connector.cpp: Added a typedef for ACE_RW_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. * tests/Conn_Test.cpp: Added a typedef for ACE_RW_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. * tests/SPIPE_Test.cpp (main): Removed the VXWORKS arm of the #ifdef, which is not correct since this stuff only works if we're working with a version of VxWorks that has STREAM pipes. * include/makeinclude/platform_sco5.0.0-nothread.GNU: Changed LIBS = -lsocket -lnsl -ldl to LIBS += -lsocket -lnsl -ldl Thanks to Ganesh Pai for reporting this. * netsvcs/lib/Client_Logging_Handler.cpp: Added a typedef for ACE_RW_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. * netsvcs/lib/TS_Clerk_Handler.cpp: Added a typedef for ACE_RW_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: Added a typedef for ACE_RW_Mutex so that the code compiles on non-MT platforms. Thanks to Ganesh Pai for reporting this. Tue Apr 15 23:16:43 1997 * ace/[Hash_]Map_Manager.cpp: The [Hash_]Map_Manager now explicitly calls the destructors of Map_Entry objects before freeing up the space. Not sure why we were not doing this before... Tue Apr 15 17:09:33 1997 Irfan Pyarali * examples/Logger: Added MSVC++ makefile to Acceptor-server and client. Tue Apr 15 21:51:45 1997 James C Hu * apps/JAWS/server/IO.cpp: Added a template instance for ACE_Singleton so it would link using GCC. Removed GCC warnings. * apps/JAWS/server/HTTP_Server.cpp: Added template instances for LOCK_SOCK_Acceptor, ACE_Task, ACE_Thru_Task, ACE_Message_Queue, ACE_Module so it would link using GCC. Removed GCC warnings. * apps/JAWS/server/HTTP_Server_T.cpp: Removed template instance of LOCK_SOCK_Acceptor, since it was not really being compiled. Tue Apr 15 21:51:45 1997 James C Hu * apps/JAWS/server/IO.cpp: Added a template instance for ACE_Singleton so it would link using GCC. Removed GCC warnings. * apps/JAWS/server/HTTP_Server.cpp: Added template instances for LOCK_SOCK_Acceptor, ACE_Task, ACE_Thru_Task, ACE_Message_Queue, ACE_Module so it would link using GCC. Removed GCC warnings. * apps/JAWS/server/HTTP_Server_T.cpp: Removed template instance of LOCK_SOCK_Acceptor, since it was not really being compiled. * apps/JAWS/server/HTTP_Handler.cpp: Removed GCC warnings. Tue Apr 15 13:01:13 1997 David L. Levine * ace/Token_Request_Reply.cpp (ctor): added initialization of transfer_.data_ to avoid unitialized memory read. * tests/test_config.h: removed "static" qualifier from randomize () to avoid warning from g++ when it's not called in a test. * examples/IPC_SAP/SPIPE_SAP/server.cpp (main): moved declaration of local variable "handle" up before its first use. Tue Apr 15 17:09:33 1997 Irfan Pyarali * examples/Connection/blocking/Makefile: Removed the Makefile for this test. This example is only suppose to work on WIN32 and therefore the Makefile is not necessary. I have replace this file with a MSVC++ make file. Mon Apr 14 23:08:27 1997 * INSTALL: Updated install files for Win32. * ace/SPIPE_Stream: Changed the use of ACE::send_n to ACE::write_n and ACE::recv_n to ACE::read_n. * ace/OS.h (WNOHANG): Added WNOHANG to OS.h for Win32. * ace/OS.i (getpgid): Fixed extra return. * examples/Connection/blocking/SPIPE-acceptor: Updated the code to use the new Proactor and the new asynchronous IO. Mon Apr 14 21:32:24 1997 David L. Levine * examples/IPC_SAP/SOCK_SAP/FD-unserver.cpp (handle_client): ACE_OS::sprintf instead of sprintf. * examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp (svc): declare "t" as time_t instead of long. Thanks to Thilo Kielmann for reporting both of these. Mon Apr 14 00:02:39 1997 Douglas C. Schmidt * ace/OS.i (getpgid): Removed the extraneous return in front of ACE_NOTSUP_RETURN. Thanks to Mike Bernat for reporting this. * ace/Process.cpp: Replaced the use of ACE_OS::fork(void) with ACE_OS::fork(const char *) so that we can pass in the name of the process we're exec'ing. * examples/Threads/process_manager.cpp: Added a test program that exercises the features of the new ACE_Process_Manager. * ace/Process_Manager: Finished a rudimentary implementation of ACE_Process_Manager. There's still plenty of work to be done on this, however... * ace/Thread_Manager.cpp (dump): Added dump() methods for ACE_Thread_Descriptor and ACE_Thread_Manager. Sun Apr 13 11:40:26 1997 Douglas C. Schmidt * ace/OS: Added a getpgid() call to ACE_OS. * ace/Thread_Manager: Changed the 'int n' of spawn_n() to size_t n since this is more appropriate because we can't spawn a negative number of threads... * ace/Thread_Manager.cpp (close): Make sure to lock the calls to close() in case things get amiss. * ace/Process.cpp (start): Updated ACE_Process::start() to that it doesn't try to exec() a program if argv == 0. This allows us to use ACE_Process to fork() a process without exec'ing. * tests/Timer_Queue_Test.cpp (randomize_array): Added a new "randomization" test that determines the performance of randomly canceling items in the array. Thanks to Darrell Brunsch for this enhancement. * tests/test_config.h: Moved the randomize() function from Naming_Test.cpp to test_config.h so that we can use it in other tests (e.g., the new Timer_Queue_Test.cpp that Darrell is working on). * ace/OS: Added a new #define called ACE_HAS_NONCONST_MSGSND which can be used for platforms (e.g., SCO) that don't have a const parameter for msgsend(). Thanks to Arturo Montes for reporting this. * ace/config-sco-5.0.0-mit-pthread.h: Added some fixes to make this work on SCO. Thanks to Arturo Montes for reporting this. * ace/OS.i (cond_timedwait): There is a *small* chance for a context switch before ACE_OS::cond_timedwait() is reached. In this case, the current time *may* advance by some milliseconds. The code in ACE_OS::cond_timedwait() then converts the given absolute time to a relative time. In the described situation this will be a very, very long t ime (0xfffffffn). Therefore, I added a check to avoid the "negative timespan" case. Thanks to Matthias Kerkhoff for suggesting this. * ace/Set: Moved all the size() methods out of the *.i file and into the *.cpp file to avoid problems with quirky compilers (e.g., SGI) that can't handle this. Thanks to Torbjorn Lindgren for pointing this out. * examples/Threads/process_semaphore.cpp (main): Removed a stray ^M that was causing the SGI C++ compiler some grief. Thanks to Torbjorn Lindgren for pointing this out. * ace/OS.i (gettimeofday): Rearranged the code a bit to return errors correctly if they occur (which should be *very* unlikely). Thanks to Torbjorn Lindgren for pointing this out. * netsvcs/lib/Server_Logging_Handler.cpp: Replaced the use of ACE_TLI* with LOGGING_PEER*. Thanks to Tom Wright for reporting this. * ace/Connector.cpp: Made sure to initialize all of the instance variables for the ACE_Strategy_Connector and ACE_Connector. Thanks to David Levine for pointing this out. * ace/Synch.h: Changed protected: to private: so that we can ensure that we never copy classes like ACE_File_Lock, etc. Thanks to Berni Merkle for reporting this. * examples/Shared_Malloc/test_malloc.cpp (malloc_recurse): Added the print_stats() call back into the test since Sandro's fixes should now support this. * ace/Malloc[_T]: Added patches to enable ACE_Allocator's to print malloc statistics. Thanks to Sandro Doro for these fixes. Sat Apr 12 20:42:11 1997 David L. Levine * tests/Priority_Task_Test.cpp (open): only use THR_SCHED_FIFO if it is defined. (It isn't on Solaris without PTHREADS.) * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp (make_svc_handler): added return statement. Sat Apr 12 11:53:49 1997 Douglas C. Schmidt * examples/ASX/Event_Server/Transceiver/transceiver.cpp (main): The first argument to connect () is now a SVC_HANDLER *&. Therefore, we can no longer allows us to pass the address of a SVC_HANDLER on the stack (or in the data segment). Fortunately, the fix is easy, as shown below: Event_Transceiver transceiver, *tp = &transceiver; connector.connect (tp, ACE_INET_Addr (port_number, host_name)); Thanks to David Levine for reporting this problem. Fri Apr 11 15:14:59 1997 David L. Levine * tests/Conn_Test.cpp: moved declaration of "result" out of loop because it's used after the loop. Thanks to Thilo Kielmann for reporting this. Also, removed a few unnecessary template specializations. * apps/Gateway/Gateway/Proxy_Handler_Connector.cpp: fixed template specializations for no-thread platforms. Thanks to Ganesh Pai for reporting this. * performance-tests/Misc/context_switch_time.cpp (main): removed call to ACE_High_Res_Timer::supported (). Fri Apr 11 14:31:42 1997 Chris Cleeland * tests/Conn_Test.cpp: Added several explicit template instantiations. Fri Apr 11 13:49:04 1997 David L. Levine * ace/OS.h: VxWorks changes only: added taskHookLib.h. Thanks to Dave Mayerhoefer for reporting that. Also rearranged the VxWorks #includes and such a bit. * ace/Log_Msg.cpp (atexit): VxWorks changes only: added cast of spare1 to ACE_Log_Msg *. Thanks to Dave Mayerhoefer for reporting that. Also, in exists () and instance (), replaced double indirection of the ACE_Log_Msg instance with indirection through a pointer reference. * ace/High_Res_Timer.{h,i}: removed supported () because ACE_OS::gettimeofday () is used if a high-res timer isn't available. * ace/OS.i (thr_sigsetmask),config-sunos5.4-*.h: swapped order of #ifdefs to that ACE_LACKS_PTHREAD_THR_SIGSETMASK is checked before ACE_HAS_STHREADS. Added that #define to all SunOS 5.4 configs. Thanks to Joey Zhu for reporting this. * ace/Token_Request_Reply.cpp (ctor): added a initializations to 0 of requeue_position_, notify_, and arg_. With this change, all of the ACE tests run without any Purify access anomalies! (There are still some memory leaks, though.) * include/makeinclude/rules.local.GNU: added -DMAKEDEPEND to invocation of g++dep. This allows users to get proper dependencies if they have conditional #includes in their code. They can added #if defined (MAKEDEPEND) as necessary to make sure that all headers are seen by g++dep. Fri Apr 11 10:46:56 1997 Chris Cleeland * config-linux*.h: Added ACE_HAS_IP_MULTICAST as the default for all Linux configurations. If you're a 1.x user, or you didn't config that into your 2.x kernel, you'll have to remove this from your version of the file. Thu Apr 10 00:34:10 1997 Douglas C. Schmidt * examples/Logger/simple-server/Logging_Acceptor.cpp (handle_input): We need to call svc_handler->close() if accept() or open() fails. Thanks to Ganesh Pai for reporting this. * ace/Service_Config.cpp (close): Moved the call to ACE_Service_Config::close_singletons() to outside the check for ACE_Service_Config::svc_rep_ since the Singletons can be used independently of the services. Thanks to Matthias Kerkhoff for suggesting this. Wed Apr 9 21:11:38 1997 Douglas C. Schmidt * apps/Gateway/Gateway/Gateway.cpp (handle_signal): Evil demons added bugs to my code that were causing segfaults when signals shutdown the gateway. This is now fixed. * apps/Gateway/Gateway/Proxy_Handler.h: Changed ACE_Event_Channel & to ACE_Event_Channel * to keep the compiler happy. * examples/Connection/non_blocking/CPP-connector.h: Added a do-nothing default constructor to keep ACE_Connector happy. * examples/Connection/misc/test_upipe.cpp: Added a do-nothing default constructor to keep ACE_Connector happy. * examples/Connection/blocking/SPIPE-connector.h: Added a do-nothing default constructor to keep ACE_Connector happy. * apps/Gateway/Gateway/Proxy_Handler: Added a do-nothing default constructor to keep ACE_Connector happy. * netsvcs/lib: Added some default arguments to TS_Clerk_Handler.cpp and Client_Logger_Handler.cpp to keep the compiler from complaining about the new ACE_Connector features. Thanks to David Levine for reporting this. * ace/Timer_Heap.cpp (reheap_down): Fixed a *very* subtle bug in reheap_down() where parent was starting off at 0 whereas it should have been starting off at child_index / 2. * examples/Logger/simple-server/Logging_Handler: Removed the use of the operator ACE_SOCK_Stream &() and replaced it with the more intuitive peer() approach used in ACE_Svc_Handler et al. Thanks to Ganesh Pai for reporting this. * ace: Added a bunch of changes to improve ACE support on SCO 5.0. Thanks to Ganesh Pai for these fixes. * tests/Conn_Test.cpp: Completely reworked this test so that it illustrates how to use the ACE_Strategy_Connector, which is customized with a special Caching_Connect_Strategy that recycles connections. * ace/Connector: Finished implementing the new ACE_Strategy_Connector. This is similar in design to the ACE_Strategy_Acceptor. * ace: Changed the signature of all the make_svc_handler() methods so that they return int (rather than SVC_HANDLER *) and they pass back a SVC_HANDLER * by reference. This makes it possible to totally control the creation of svc handlers (which is useful for the new ACE_Strategy_Connector). * ace/Connector.cpp: Factored out the active_svc_handler() call from the connect_svc_handler() method into the connect() method so that it would behave correctly as a Template Method and Strategy. * ace/Connector: Removed the explicit use of the Reactor data member from the ACE_Connector since it's inherited from the ACE_Service_Object. * ace/Log_Msg.cpp: The MVS compiler doesn't like the call to atexit() in ACE_Log_Msg::instance() because atexit() requires an a function pointer of type extern "C" for its parameter. I've fixed this via an adapter. Thanks to Chuck Gehr for reporting this. * ace/Strategies_T: Added a new ACE_Connect_Strategy that complements the ACE_Strategy_Connector in the same manner that the ACE_Accept_Strategy complements the ACE_Strategy_Acceptor. * ace/Connector.h: The destructor for ACE_Connector should have been virtual. Now it is. * ace/Connector: Added a new factory method called make_svc_handler(). This behaves similiarly to the ACE_Acceptor::make_svc_handler(). However, for the ACE_Connector we only use this when the SVC_HANDLER * is NULL. * ace/Connector: Changed the signature for connect() to take a & to a SVC_HANDLER * in anticipation of our new ACE_Strategy_Connector. This new connector will make it easy to implement cached connections. * ace/config-win32-common.h: Added a new #include for , which contains the declarations for TransmitFile() data structures. They are in WINSOCK.H if you do not use ACE_HAS_WINSOCK2. Thanks to Norbert Rapp for reporting this. * ace/OS.i: Fixed a typo in the new condition variable implementation for Win32. Thanks to Norbert Rapp for reporting this. Wed Apr 09 22:06:23 1997 * Memory_Pool.h: Modified ACE_MMAP_Memory_Pool and ACE_MMAP_Memory_Pool_Options to include the new guess_on_fault option. This is only for platforms that can not report which address caused a segmentation fault (via signal or exception). When guess_on_fault is set (via ACE_MMAP_Memory_Pool_Options), ACE_MMAP_Memory_Pool::handle_signal calls ACE_MMAP_Memory_Pool::remap "guessing" that the segmentation fault was caused by an access to memory not yet mapped. Wed Apr 09 16:46:16 1997 David L. Levine * ace/OS.{h,i}: fixed readPPCTimeBase declaration and return value (for now: it really needs to return a 64 bit quantity). Thanks to Dave Mayerhoefer for reporting these. Wed Apr 9 03:12:24 1997 Irfan Pyarali * ace/config-win32-common.h: Defining _WIN32_WINNT as 0x0400 implies ACE_HAS_WINSOCK2. * ace/Asynch_IO: The implementation of ACE_Asynch_Transmit_File and ACE_Asynch_Accept are only supported if ACE_HAS_WINSOCK2 is defined or you are on WinNT 4.0 or higher. Therefore, added appropriate #defines. Thanks to Matthias Kerkhoff for suggesting this. Tue Apr 8 22:45:28 1997 Prashant Jain * java/src/SOCKStream.java (SOCKStream): Made two small changes to the two send(). Instead of doing a println, I now do a print. This was really a bug! Tue Apr 08 22:08:12 1997 David L. Levine * include/makeinclude/platform_sunos5_sunc++_4.1.GNU: removed "rm -f $@" from AR command so that archive won't be removed during incremental updates. Thanks to Chuck Gehr for reporting this. Tue Apr 8 00:04:22 1997 Douglas C. Schmidt * ace/Task_T.cpp: Added a hack to work around the new weird HP/UX aCC template semantics. Thanks to Neil B. Cohen for reporting this. * ace/config-hpux-10.x[-g++].h: Added #define ACE_HAS_CLOCK_GETTIME. Thanks to Neil B. Cohen for reporting this. * ace/config-hpux-10.x[-g++].h: Added ACE_HAS_IP_MULTICAST and removed ACE_LACKS_STRRECVFD. Thanks to Neil B. Cohen for reporting this. * ace/config-hpux-10.x.h: Apparently some HP/UX 10.x C++ compilers don't support volatile, so I #defined it away as a macro. Thanks to Neil B. Cohen for reporting this. * ace/Log_Msg.cpp: Put a #if defined (ACE_MT_SAFE) around the entire Log_Msg destructor. Thanks to Neil B. Cohen for reporting this. * ace/config-hpux-10.x[-g++].h: Added #define ACE_HAS_STREAMS on the recommendation of Neil B. Cohen . Mon Apr 07 12:08:21 1997 * ace/Set.cpp: For some reason, VC++ 5.0 doesn't like to have the constructors X::X(X&) and X::X(X*). We can change the X::X(X*) constructor to take in an extra argument with a default value. This seems to have sufficiently satisfied the VC++ 5.0 for the time being. There were no changes necessary to other Set.cpp code (as the extra argument has a default value). Mon Apr 07 08:05:03 1997 David L. Levine * ace/config-win32.h: enabled ACE_HAS_UNICODE by default. Thanks to Matthias Kerkhoff for suggesting this. * ace/config-sunos5.4-g++.h: enabled ACE_HAS_BROKEN_RANDR and disabled ACE_HAS_SVR4_SIGNAL_T. Thanks to Joey Zhu for reporting these problems and testing the fix. * ace/Proactor.h (ACE_Proactor): commented out unused arguments in non-WIN32 version. Sun Apr 06 22:51:02 1997 * ace/Proactor: Complete rewrite of Proactor that pushes all the differences in asynchronous I/O to the edges of the framework - i.e., into the new Asynch_IO classes. This allows the Proactor to easily support new asynchronous operations. Currently, the new Proactor supports minimal functionality. In the future, we will complete this. The Proactor is used in conjunction with the new Asynch_IO classes. There is a different class for each operation. Please see Asynch_IO.h for details. There is also a new ACE_Asynch_Acceptor that uses AcceptEx. Example is in: ACE_wrappers/examples/Reactor/Proactor/test_proactor.cpp. This example illustrates how the ACE_Proactor can be used to implement an application that does various asynchronous operations. * apps/JAWS/server: Complete rewrite of JAWS. The new JAWS has support for Asynch-Thread-Pool (on WIN32), Synch-Thread-Pool, and Thread-per-Request. Different models can be configured using the svc.conf file. The server now supports both GET and PUT commands. The HTTP_Handler class is a state based implementation of the HTTP protocol. Therefore, it can be used synchronously and asynchronously. It uses an abstract IO class to move between different HTTP protocol states. It is up to the IO class to decide on synchronous or asynchronous I/O. * apps/JAWS/client: This is an example of the implementation of BlobStreaming in ACE. This version of BlobStreaming uses HTTP as a transport protocol. Blobby :-) is a simple application written using the ACE_Blob class, which is capable of doing both file uploads and downloads. If a file is downloaded, the downloaded data is sent to standard output, so that it can be piped as necessary. * ace/Mem_Map.cpp (map_it): This method now uses ACE_OS::pwrite (if ACE_HAD_P_READ_WRITE is defined) instead of ACE_OS::lseek/ACE_OS::write to write the end-of-file byte. The old scheme does not work if the file is in OVERLAPPED mode. * ace/OS: Added pread and pwrite to the OS class (if ACE_HAD_P_READ_WRITE is defined). On Win32, these functions use the OVERLAPPED structure to specify the offset. This implementation will block until the write/read completes (even if the file is in OVERLAPPED mode). * ace/config: Added ACE_HAS_P_READ_WRITE to the following platforms that support pread() and pwrite() calls: config-sunos4-g++.h config-sunos4-lucid3.2.h config-sunos4-sun3.x.h config-sunos4-sun4.1.4.h config-sunos4-sun4.x-orbix.h config-sunos4-sun4.x.h config-sunos5.4-centerline-2.x.h config-sunos5.4-g++.h config-sunos5.4-sunc++-4.x-orbix.h config-sunos5.4-sunc++-4.x.h config-sunos5.5-g++.h config-sunos5.5-sunc++-4.1.h config-sunos5.5-sunc++-4.x-orbix.h config-sunos5.5-sunc++-4.x.h config-sunx86-sunc++-4.x.h config-win32-common.h Sun Apr 6 14:16:18 1997 Douglas C. Schmidt * tests/Timer_Queue_Test.cpp: Added tests to make sure that the new ACE_Timer_Queue::cancel() logic is working correctly. So far, it seems to be fine. * ace/Timer_{Heap,List}.cpp (cancel): Changed the comparison for dont_call_handle_close to be correct. * ace/OS.cpp: Deleted a useless return. Thanks to Gonzalo A. Diethelm for reporting this. * ace/config-irix6.2-sgic++.h: Added the following definitions: + ACE_LACKS_PTHREAD_THR_SIGSETMASK + ACE_HAS_PTHREAD_EQUAL + ACE_HAS_PTHREAD_T + ACE_HAS_SYSENT_H + ACE_HAS_SYSINFO + ACE_HAS_TEMPLATE_TYPEDEFS Deleted the following definitions: + #define ACE_HAS_SYS_SIGLIST (Irix's compiler only has a _sys_siglist array when compiling their own internal functions). Thanks to Gonzalo A. Diethelm for this. * ace/Process: Added new support for setting the environment variable and the current working directory. Thanks to Gonzalo A. Diethelm for this enhancement. * ace/OS.h: "sys/stat.h" was being included more than once, so I fixed this. Thanks to Gonzalo A. Diethelm for reporting this. * ace/XtReactor.cpp: Added the register_handler_i() method, which just delegates to the one defined in the Reactor. This is necessary to adjust to the C++ type system rules. Thanks to Gonzalo A. Diethelm for reporting this. * ace/Service_Config.cpp: Added the Double-Checked Locking Optimization pattern to all the ACE_Service_Config Singletons (e.g., thr_mgr(), reactor(), etc.) so that they behave correctly in multi-threaded programs. Thanks to Matthias Kerkhoff for insisting on this. * ace/OS.i (nanosleep): If the nanosleep() system call isn't supported by the OS platform we'll just use ACE_OS::sleep(const ACE_Time_Value &) instead. * ace/Log_Msg.cpp: Changed the logic of ACE_Log_Msg_Manager::remove() so that it returns the number of remaining registered instances. When this goes to 0 we'll cleanup. * ace/OS.i: Enhanced the ACE_OS::cond_[timed_]wait() methods so that they use SignalObjectAndWait() whenever possible to avoid potential problems with unfairness. See http://www.cs.wustl.edu/~schmidt/editorial-15.html for more details. Thanks to David Holmes for pointing out this subtlety. Sun Apr 06 20:01:57 1997 David L. Levine * include/makeinclude/wrapper_macros.GNU: added "purify" and "quantify" make command options. To build Purified versions of all executables in the current direction, for example: % make clean; make purify=1 These options assume that purify or quantify are in your PATH. * ace/Task.{h,cpp}: removed ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES from ACE_Task_Exit declaration and ACE_Task_Exit::instance (). ACE_Task_Exit is no longer a template class, so we don't need that. * ace/Task_T.h: added missing "*/" at end of comment after #endif. * tests/IOStream.cpp (server): added check for 0 strlen of "buf" to avoid out-of-bound array reference. * ace/Svc_Conf_l.cpp, Makefile: added #define ACE_BUILD_DLL. Thanks to Matthias Kerkhoff for reporting this. * ace/Set.cpp(ACE_Set_Node ctor): commented out unused arg MS_SUCKS. Sat Apr 5 14:21:29 1997 Prashant Jain * java/: Changed package name from ACE to JACE across all directories. Sat Apr 5 13:12:37 1997 Douglas C. Schmidt * tests/MM_Shared_Memory_Test.cpp: Removed the use of dynamic memory allocation to avoid memory leaks. * ace/Service_Config: Changed _defaults to _static_svcs since this more accurately reflects what they do. * examples/Shared_Malloc/test_malloc.cpp: Removed the print_stats() call since it doesn't work via this API. Thanks to Sandro Doro for reporting this. * ACE-install.sh: Tweeked the install script by changing the "gunzip; tar; gzip" sequence into "gunzip -c | tar xvf -" to speed it up a little. Thanks to Per Andersson for this fix. * examples/Threads/future1.cpp: Make sure to delete the char *name that is retrieved from the future in order to avoid a memory leak. Thanks to Matthias Kerkhoff for figuring this out. * examples/Threads/future1.cpp: Make sure to delete this->name_ in the Scheduler destructor to avoid a memory leak. * examples/Threads/task_four.cpp (close): Enhanced the close() method so that it will actually delete the memory for the Worker_Task. * ace/XtReactor.cpp (register_handler_i): Added the if (mask & ACE_Event_Handler::ACCEPT_MASK) ACE_SET_BITS (condition, XtInputReadMask); Thanks to Jean-Marc Strauss for reporting this. * ace/Timer_Queue.cpp (expire): This is the only method that calls ACE_Timer_Queue::cancel() with dont_call_handle_close set to 0. * ace/Reactor: Modified the cancel_timer() methods so that they also take a dont_call_handle_close parameter and pass it on to the Timer_Queue::cancel() method. * ace/Timer_{List,Heap}.cpp: Modified all the cancel() methods so that they will not call handle_close() unless the new parameter dont_call_handle_close is 0 (it is 1 by default). This will avoid nasty problems with recursion. Thanks to Paul Han for suggesting this. * ace/Timer_{List,Heap}.cpp (schedule): If a user tried to schedule a NULL ACE_Event_Handler then we return -1 with errno set to EINVAL. * ace/Message_Block.cpp: Somehow the file got screwed up and was reverted back to an earlier incarnation where we didn't use ACE_Service_Config::alloc()... Thanks to Matthias Kerkhoff for figuring this out. Sat Apr 5 19:11:46 1997 Tim H. Harrison * ace/Signal.i (ACE_Sig_Guard): Changed the constructor of ACE_Sig_Guard so that it doesn't call ACE_OS::sigprocmask for Win32. This keeps errno from being set to ENOSYS at random times. Sat Apr 05 17:27:02 1997 * Registry.cpp (resolve): Type and size of the object is only set if RegQueryValueEx() returns success. Thanks to Alan (Alan_Cabrera@fp.cibc.com) for reporting this. Sat Apr 05 13:11:04 1997 David L. Levine * ace/Log_Msg.cpp (instance): Added another ACE_NO_HEAP_CHECK. Matthias provided the fix. * ace/config-win32.h: Disable ACE_HAS_STRICT by default, because it will break existing application code. * ace/OS.{h,cpp},Log_Msg.{h,cpp}: fixes from Matthias Kerkhoff to avoid memory-leak reports when MFC or (the CrtHeapXXX()-functions of the Win32 runtime library) are used. The problem is, that MFC (and so may other Win32 applications do) allocates a thread specific storage slot for each running thread which contains various control and debug informations. Part of this information is an object, which when constructed makes a snapshop of the heap. When this object is destroyed, the snapshot is compared to the actual heap. All object still existing on the heap are reported as memory leaks (which is in most situations correct). Because the object is deleted when the thread (or programs main) is left and this happens before atexit is called, some leak reports are false (because, e.g., all these ACE_Log_Msg's will be deleted in atexit). The fix for ACE_Log_Msg consists of three changes (two only relevant for Win32, one relevant for all platforms.) Description of changes: a) Introduced a new macro ACE_NO_HEAP_CHECK, which turns off the built in heap checking until the current code block is left. (defined for all platforms, but only does something for Win32). This changes os.h and config-win32-common.h. b) Added a static member function to ACE_Log_Msg. The function (exists) returns 0 if the calling thread don't have an ACE_Log_Msg and non-null if an ACE_Log_Msg exists. This changes Log_Msg.h and Log_Msg.cpp. c) Changed ACE_Thread_Adapter in a way that creating a new thread does not automatically create an ACE_Log_Msg for the calling thread. This happened until now, because the new thread inherited the log settings of the calling thread. This behaviour makes no sense, if the calling thread does not have an ACE_Log_Msg, so i use ACE_Log_Msg::exists() (see above) to prevent the implicit creation of an ACE_Log_Msg for the calling thread. Thanks, Matthias! * ace/config-win32.h and config-win32-common.h: new, consolidated Win32 config files. Thanks, again, Matthias! * ace/OS.h (ACE_UNUSED_ARG): determine whether we're building on an Irix platform by looking for ACE_HAS_IRIX_GETTIMEOFDAY instead of ACE_HAS_IRIX62_THREADS. * ace/Log_Msg.cpp: VxWorks (only!) change: no longer strdups program_name and local_host to avoid memory leaks. Instead, the addresses of these are copied by ACE_Log_Msg. So, only strings in the text segment should be passed to its functions! Again, this change is for VxWorks only. * ace/Sched_Params.cpp: moved memsets of pcinfo so that entire pcinfo structure is zeroed out, to _really_ avoid Purify warnings. Fri Apr 04 12:28:40 1997 David L. Levine * ace/config-mvs.h: removed ACE_HAS_IP_MULTICAST because MVS doesn't define ip_mreq. Thanks to Chuck Gehr for reporting this. * ace/OS.i (mutex_init): fixed the extra braces once and for all. Thanks to Chuck Gehr for reporting it. * ace/OS.i, config-sco-5.0.0*.h: fixed for SCO so that it uses single-argument gettimeofday () prototype, but calls two-arg (SVR4) version in ACE_OS::gettimeofday (). Thanks to Ganesh Ganesh Pai for solving this problem. * ace/Log_Msg.{h,cpp}: added ACE_Log_Msg destructor. In instance (), added call to ::atexit () (::taskDeleteHookAdd () on VxWorks) to register cleanup handler. Each new instance of an ACE_Log_Msg is inserted into an ACE_Unbounded_Set; the cleanup handler iterates over the Set and deletes the ACE_Log_Msgs at program exit. Also, the two strings that are allocated get cleaned up after the last ACE_Log_Msg instance is deleted. Many thanks to Matthias Kerkhoff for figuring this out and cranking out the code. It works differently on VxWorks, because it doesn't have ::atexit (). VxWorks has ::taskDeleteHookAdd (), which is called when each task exits. So, the Set isn't used. Instead, the cleanup hook is called for each task when it exits, passing the task control block (TCB) of the exiting task. A pointer to the ACE_Log_Msg instance is contained in one of the spare fields of the TCB, so the cleanup handler simply deletes it. * ace/IOStream.h: specify template parameter (ACE_IOStream) to ACE_OPERATOR{G,P}_SET macros. Thanks to Chuck Gehr for providing this fix. Thu Apr 3 22:17:53 1997 Irfan Pyarali * ace/Registry.cpp: Changed STRING_SEPARATOR from Istring to LPCTSTR. Thanks to Matthias Kerkhoff for suggesting this. Thu Apr 3 21:39:45 1997 Chris Cleeland * ace/OS.i (mutex_init): Removed errant open-brace ('{'). Thanks to Chuck Gehr (gehr@sweng.stortek.com) for the fix! Thu Apr 03 08:52:34 1997 David L. Levine * ace/OS.h,OS.cpp,Sched_Params.cpp: added /**/ to some #include directives. Thanks to Matthias Kerkhoff for reporting these. * ace/OS.cpp (writev, readv): changed type of local variable "i" from size_t to int to avoid signed/unsigned mismatch. Thanks to Matthias Kerkhoff for reporting this. * ace/OS.cpp (readv), SOCK_Dgram.cpp (recv): added casts of iov_len and copyn because iov_len is int on some platforms and size_t on others. This avoids compiler (MSVC 4.1) warnings. Thanks to Matthias Kerkhoff for reporting this. * include/makeinclude/platform_sco5.0.0-nothread.GNU: updated CCFLAGS and added LD=$(CXX). Thanks to Ganesh Pai for these fixes. * ace/OS.h: added #include of for SCO only. Thanks to Ganesh Pai for this fix. * ace/config-sco-5.0.0*.h: added #define ACE_HAS_IP_MULTICAST. Thanks to Ganesh Pai for this fix. * ace/config-{chorus,linux*,sco*}.h: removed #define of ACE_HAS_INLINED_OSCALLS because it's no longer needed in the config files: it's #defined in OS.h if needed. Thu Apr 3 01:48:01 1997 Tim H. Harrison * ace/Malloc.i (malloc): ACE_New_Allocator::malloc only calls new if nbytes is > 0. Purify was complaining that 0 bytes were allocated but never deleted. Go figure. Wed Apr 2 22:24:48 1997 Douglas C. Schmidt * ace/OS.cpp: Moved the ACE_OS::inet_aton() method into the *.cpp file and made it non-inline to work around a bug with HP/UX C++. Thanks to Neil Cohen for this fix. Wed Apr 02 10:09:37 1997 David L. Levine * ace/config-sunos5.5-sunc++-4.1.h: added template specialization with Sun C++ 4.2. * include/makeinclude/platform_sunos5_sunc++_4.1.GNU: removed +w and added comments about Sun C++ 4.2 support. * include/makeinclude/platform_chorus.GNU, platform_hpux_gcc.GNU, platform_irix5.{2,3_g++}.GNU, platform_linux{_,pthread}.GNU, platform_m88k.GNU,platform_osf1_4.0_g++.GNU, platform_sco-nothread.GNU,platform_sco5.0.0-*.GNU, platform_sunos{4,5}_g++.GNU, platform_sunos5_x86_g++.GNU, platform_unixware_g++.GNU, platform_vxworks5.2_g++.GNU: added -fno-implicit-templates to CCFLAGS. See INSTALL file for discussion of the g++ option. Also, added -O2 because it dramatically reduces object file sizes. * netsvcs/clients/Tokens/manual/manual.cpp: made STDIN_Token::TID typedef public so that template specialization (w/ Sun C++ 4.2) can access it. Wed Apr 2 10:02:47 1997 Chris Cleeland * ace/OS.h: Added definitions for THREAD- and PROCESS-LEVEL priorities because some implementations define these while others don't. These are now ACE_{THR,PROC}_{FIFO,RR,OTHER}_{MIN,MAX,DEF}. The only really NEW concept is the *_DEF, which is a default value assigned by ACE_OS::thr_create() if one isn't given. Of special note is that we don't redefine a default values if it's already been defined, which allows individual programs to have their own ACE-wide "default". * ace/OS.cpp (thr_create): Uses ACE_{THR,PROC}_* macros rather than the PRI_* macros. * ace/Sched_Params.cpp (priority_min,priority_max): These now use ACE_{THR,PROC}_* macros to ignore OS-specific priority assignments. * ace/config-linux-lxpthreads.h: Removed definitions of PRI_{FIFO,RR,OTHER}_{MIN,MAX}. * include/makeinclude/platform_linux*.GNU (CCFLAGS): Added -fno-implicit-templates now that it's supported. This eliminates messages of the sort 'ld: Warning size of change from xx to yy' when linking libACE.so. Thanks to David Levine for making this possible! Tue Apr 1 15:27:28 1997 Douglas C. Schmidt * bin/g++dep: Removed the "/bin" prefix so that this won't fail on platforms that don't have sed in /bin. Thanks to Sandro Doro for this fix. Tue Apr 01 09:55:07 1997 David L. Levine * ace/OS.h: protected definition of struct flock on VxWorks, because it defines that type in sys/fcntlcom.h. (It doesn't appear to support flock (), though.) Thanks to Dave Mayerhoefer for reporting this. * ace/OS.h: define ACE_hrtime_t as u_longlong_t gcc, because its long long types are only 4 bytes long. Its longlong_t types are 8 bytes. Also made ACE_hrtime_t unsigned for other than gcc on Unix platforms. * ace/OS.* (gethrtime), config-vxworks-ghs-1.8.h: added support for PowerPC with Green Hills compiler. Thanks to Dave Mayerhoefer for providing the readPPCTimeBase assembler routine. * ace/config-vxworks*.h: removed #include of vxWorks.h because its no longer necessary with the TimeValue.h merged into OS.h. * ace/High_Res_Timer.cpp (elapsed_time): added cast to initialization of nseconds to avoid compiler warning from MSVC 4.1 about narrowing from unsigned __int64. Thanks to Matthias Kerkhoff for reporting this. Mon Mar 31 18:18:35 1997 Carlos O'Ryan * ace/config-hpux-10.x-g++.h: It was tuned to HP-UX 10.10 (and further) using g++ 2.7.2 without DCE/Threads. * ace/Task_T.cpp: Another iteration on the Module.h file, this time it is not included *only* under HPUX and when using HP/aCC. Still IMHO problems will arise as template sintax checking becomes more popular. * ace/Local_Name_Space_T.h: * ace/Local_Name_Space_T.cpp: Replaced MAXNAMELEN with MAXPATHLEN since some platforms (e.g., HP/UX) have a very low value (e.g., 14 bytes) for MAXNAMELEN. * ace/config-hpux-10.x-aCC.h: The comment did not make clear what was compiler/platform target. It also included some remarks that only applied to HP/C++. * tests/Future_Test.cpp: * tests/Message_Block_Test.cpp: * tests/Thread_Pool_Test.cpp: Will not compile if ACE_HAS_THREADS was not defined and ACE_TEMPLATES_REQUIRE_SPECIALIZATION was: they tried to instantiate templates that were only defined when ACE_HAS_THREADS. * ace/config-hpux-10.x-aCC.h: More fine tuning: ACE_HAS_EXCEPTIONS, ACE_LACKS_LINEBUFFERED_STREAMBUF, ACE_HAS_STREAM_PIPES. * ace/TLI_Stream.h: * ace/TLI_Acceptor.h: No "Meta-type info" was defined (the PEER_ADDR and PEER_STREAM typedefs). * ace/Signal.h: * ace/Signal.cpp: With HP/aCC we can enable ACE_Sig_Handlers. Mon Mar 31 22:36:55 1997 Douglas C. Schmidt * ace/Service_Config.cpp (process_directives): Return -1 if ace_yyerrno > 0. Thanks to Alan Cabrera for reporting this. Mon Mar 31 17:38:08 1997 Chris Cleeland * ace/OS.cpp (thr_create): Moved priority determination after policy determination because it's possible for setting of the priority to fail if it's not a valid priority for the [default] policy. Mon Mar 31 09:00:54 1997 David L. Levine * performance-tests/Misc/context_switch_time.cpp: this test no longer worked. So, reverted to revision 4.5, plus minimum changes necessary to support build on platforms without threads. * examples/Threads/Makefile, performance-tests/Misc/Makefile: moved context_switch_time.cpp from examples/Threads to performance-tests/Misc. * examples/Logger/Acceptor-server/server_loggerd.cpp, examples/Reactor/Misc/pingpong.cpp, examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp, examples/Shared_Malloc/Malloc.cpp: added template specializations. * include/makeinclude/platform_sunos5_g++.GNU: removed dependency of CCFLAGS on CFLAGS to avoid duplicate -g in build command. Also, added -fno-implicit-templates in comment. Sun Mar 30 12:52:58 1997 Douglas C. Schmidt * ace/Malloc.h: The block begining with: #if defined (ACE_MALLOC_STATS) and ending with end of struct ACE_Malloc_Stats must be moved (up) after line 107 Thanks to Sandro Doro for pointing this out. * ace/Malloc_T.cpp: The line this->malloc_stats_.dump (); must be changed in: this->cb_ptr_->malloc_stats_.dump (); Thanks to Sandro Doro for pointing this out. * ace/Malloc_T.cpp: the line this->cb_ptr_->malloc_stats_.print (); // print not exists may be changed in: this->cb_ptr_->malloc_stats_.dump (); Thanks to Sandro Doro for pointing this out. * ace/Malloc_T.h: Added "virtual" to the ACE_New_Allocator methods to reinforce the fact that they are indeed virtual. Thanks to Sandro Doro for pointing this out. * ace/Malloc.h: Added "virtual" to the ACE_New_Allocator methods to reinforce the fact that they are indeed virtual. Sat Mar 29 20:26:54 1997 David L. Levine * ace/OS.h: moved #defin of RTLD_LAZY after #include of dlfcn.h. Thanks to Chris Lahey for this fix. * ace/Task_T.h: replaced #include of "ace/Module.h" because some Task_T methods use ACE_Module methods. * examples/Connection/non_blocking/test_{sock,spipe,tli}_{acceptor, connector}.cpp, examples/System_V_IPC/SV_Semaphores/Semaphores_{1,2}.cpp: added template specializations. Sat Mar 29 17:08:33 1997 Douglas C. Schmidt * ace/OS.cpp: Added many new ACE_UNUSED_ARGS macros to eliminate warnings when we are compiling without threads. Fri Mar 28 11:34:38 1997 David L. Levine * ace/Task.{h,cpp},Thread_Manager.h: changed remaining priority types to long and defaults to -1. * ace/Thread_Manager.cpp (spawn_i): don't clobber errno! ACE_OS::thr_create () sets errno and returns -1. So, its return value should not be used to set errno. * ace/OS.cpp (thr_create): fixed PTHREADS_1003_DOT_1C thread priority logic. Thanks to Thilo Kielmann for the patch. * ace/config-sunos5.5*.h,README,OS.cpp (thr_create): added ACE_HAS_ONLY_SCHED_OTHER to indicate that platform (Solaris 2.5) only supports POSIX SCHED_OTHER scheduling policy. * tests/Priority_Task_Test.cpp (open): added THR_SCHED_FIFO flag. Thanks to Thilo Kielmann for for this suggestion. * examples/ASX/Event_Server/Event_Server/Makefile, Transceiver/Makefile: added -lGateway to LIBS to pick up its template instantiations during links. * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp, Transceiver/transceiver.cpp, Connection/blocking/SPIPE-{acceptor,connector}.cpp, misc/Connection_Handler.cpp,test_upipe.cpp, Logger/simple-server/server_loggerd.cpp, UPIPE_Event_Server/{Consumer,Supplier}_Router.cpp, performance-tests/Synch-Benchmarks/Options.cpp: added template specializations. Thu Mar 27 21:10:59 1997 David L. Levine * ace/IOStream.h: only use built-in ipfx{0,1} () with __GNUC__, because that's the only compiler we know of that has them. Thanks to Carlos O'Ryan for pointing this out, and to James CE Johnson for providing the fix. * ace/OS.i: rearranged order of ACE_Time_Value functions (moved set ()'s up, moved arithmetic operators down) so that they are defined before use. * ace/Task_T.cpp: removed ACE_TEMPLATES_REQUIRE_SOURCE around #include of "ace/Module.h" so that it will build with Sun C++ 4.1. * apps/Gateway/Peer/Makefile: added -lGateway to LIBS to pick up its template instantiations during links. * apps/Gateway/Peer/Peer.cpp: added template instantations. Thu Mar 27 14:10:39 1997 Douglas C. Schmidt * ace/OS.h: Added two new accessors to ACE_Time_Value: operator timeval *() const; // Returns a pointer to the object as a timeval. const operator timeval *() const; // Returns a pointer to the object as a timeval. Thanks to Carlos O'Ryan for this suggestion. * ace/OS.i (ACE_Time_Value): Inlined many of the ACE_Time_Value accessors. * ace/OS.h: Reimplemented ACE_Str_Buf at struct ACE_Export ACE_Str_Buf : public strbuf { // = Initialization method ACE_Str_Buf(void* b = 0, int l = 0, int max = 0); // Constructor. }; this makes the casting from ACE_Str_Buf* to strbuf* a "safe" cast and makes it more portable (say on platforms where the fields in strbuf are not in the right order). Thanks to Carlos O'Ryan for this fix. * ace/OS.h: Moved the definition of imr_multiaddr to just before class ACE_OS so that it picks everything up appropriately. Thanks to Hakan Kallberg for reporting this. * ace/config-aix-4.[12].x.h and config-mvs.h: Fixed the ACE_HAS_MULTICAST macros, which should have said ACE_HAS_IP_MULTICAST. Thanks to Daniel Montalibet for reporting this. Thu Mar 27 15:54:10 1997 Chris Cleeland * ace/{Thread,Thread_Manager}.{h,i,cpp} (ACE_Thread): Changed type for priority arg to spawn*() from u_int to long to support changes in thr_create indicated below. Thanks to Thilo Kielmann for these changes. * ace/OS.cpp: Ensure that whenever either a priority of a scheduling policy is set explicitly, with POSIX threads, the other argument and the flag THR_EXPLICIT_SCHED is set automatically. A range check for priority values for POSIX 1003.1c is also included. Thanks to Thilo Kielmann for these changes. * ace/OS.h: Changed type and default value of priority arg to thr_create from u_int to long and 0 to -1. Thanks to Thilo Kielmann for these changes. Also added ACE_MAX and ACE_MIN macros. Thu Mar 27 11:25:38 1997 David L. Levine * netsvcs/servers/Makefile: removed SHOBJ so that main.so is not built, because it wasn't needed. Thanks to Sandro Doro for this fix. * ace/config-aix-4.[12].x.h,config-mvs.h: changed ACE_HAS_MULTICAST to ACE_HAS_IP_MULTICAST. Thanks to Daniel Montalibet for reporting this. * include/makeinclude/platform_sunos5_g++.GNU, platform_sunos5_x86_g++.GNU, platform_unixware_g++.GNU: removed "-L$(WRAPPER_ROOT)/ace -L./" from LDFLAGS because it is added to LDFLAGS in include/makeinclude/wrapper_macros.GNU. * apps/Gateway/Gateway/{Event_Channel.cpp,Gateway.cpp, Proxy_Handler.cpp,Proxy_Handler_Acceptor.cpp, Proxy_Handler_Connector.cpp, examples/IPC_SAP/UPIPE_SAP/ex{2,3}.cpp, netsvcs/clients/Naming/Client/Client_Test.cpp, netsvcs/clients/Tokens/manual/manual.cpp: added template specializations. Thu Mar 27 10:05:59 1997 Prashant Jain * netsvcs/lib/TS_Clerk_Handler.cpp: Fixed two things: 1) In TS_Clerk_Processor::parse_args() changed "%n:\n[-p hostname:port] [-t timeout] [-p poolname]\n%a", 1), to "%n:\n[-h hostname:port] [-t timeout] [-p poolname]\n%a", 1), 2) In TS_Clerk_Processor::alloc() changed void *temp = 0; // Only create the state if it doesn't already exist. if (this->shmem_->find (ACE_DEFAULT_TIME_SERVER_STR, temp) == -1) { // Allocate the space out of shared memory for the system time entry temp = this->shmem_->malloc (sizeof (this->system_time_)); to: // Only create the state if it doesn't already exist. if (this->shmem_->find (ACE_DEFAULT_TIME_SERVER_STR) == -1) { // Allocate the space out of shared memory for the system time entry void *temp = this->shmem_->malloc (sizeof (this->system_time_)); Thanks to Sandro Doro (alex@aureus.sublink.org) for suggesting these changes. Thu Mar 27 01:00:18 1997 Douglas C. Schmidt * include/makeinclude/platform_irix6.2_sgiCC.GNU: Added a new platform config file for SGI Irix 6.2 using the CC compiler (not NCC nor the MipsProcompiler). Thanks to Eric Dean Russell for these changes. * ace/OS.h: Moved the ACE_LACKS_UTSNAME_T block into the right part of the code. Thanks to Jonathan Biggar for this fix. * ace/Malloc.h: Added an enhancement so that the new alignment features will work regardless of the size of ACE_MALLOC_ALIGN. Thanks to Fred LaBar for this fix. * ace/Synch_Options.cpp: We now automatically set the USE_TIMEOUT flag if a non-0 timeout value is supplied. Thanks to Tim Liddelow for this suggestion. Wed Mar 26 08:47:24 1997 David L. Levine * ace/{ACE.cpp,Log_Msg.cppOS.cpp}, tests/{Message_Queue_Test.cpp,Naming_Test.cpp}: Changed ::sprintf calls to ACE_OS::sprintf. Thanks to Thilo Kielmann for reporting this. * netsvcs/lib/{Client_Logging_Handler.cpp,Name_Handler.cpp, Server_Logging_Handler.cpp,TS_Service_Handler.cpp, Token_Handler.cpp}: added template specializations. Tue Mar 25 06:47:14 1997 Douglas C. Schmidt * ace/OS.h: Moved config.h to the top of OS.h so that we don't have to worry about not defining things in the right place. Thanks to Matthias Kerkhoff for pointing this out. Tue Mar 25 22:54:49 1997 Irfan Pyarali * ace/OS.i: Added UNICODE support for ACE_OS::chdir(). Thanks to Ivan Murphy for the code. Tue Mar 25 21:26:10 1997 David L. Levine * ace/TTY_IO.{h,cpp},README, and these config files: config-aix-*.h, config-hpux-*.h, config-irix5.*.h, config-mvs.h, config-osf1-*.h, config-sun*.h (except for g++ and config-sunos5.5-sunc++-4.1.h), config-win*.h: Added ACE_NEEDS_DEV_IO_CONVERSION to conditionally compile the ACE_DEV_IO & conversion operator for ACE_TTY_IO, which is a subclass of ACE_DEV_IO. Thanks to Fred LaBar and Gonzalo Diethelm for reporting warnings without this on Irix 6.2 with the mipsPro compiler. * ace/OS.cpp (thr_create): on VxWorks, always pass 0 as first arg to ::taskSpawn () so that VxWorks will generate the task ID. Thanks to Dave Mayerhoefer for providing this fix, without which random task names would be assigned. * ace/ACE.cpp (get_bcast_addr): added return 0 at end of non-WIN32 code to avoid compile warning from g++. * tests/IOStream_Test.cpp: removed extra "(%P|%t)" from output. I couldn't get ACE_ERROR_RETURN to work on g++: it complained about mismatched return types when returning an int from a function that returns a void *, and about mismatched arguments to an ACE_Log_Msg function if I cast the int to a void *. So, I used ACE_ERROR instead. Added ACE_UNUNSED_ARG (arg). Removed unused variables error_at_server and error_at_client. * netsvcs/lib/TS_Clerk_Handler.cpp: added another template specialization. * examples/Reactor/Multicast/client.cpp: Log_Wrapper::LOG_DEBUG instead of LM_DEBUG. * examples/Threads/context_switch_time.cpp: use ACE_Sched_Params to get platform-dependent thread priorities. Also, moved #includes so that config.h is read before testing for ACE_HAS_THREADS. * examples/Threads/{auto_event.cpp,barrier2.cpp,future1.cpp, future2.cpp,reader_writer.cpp,tss1.cpp,tss2.cpp}: added template specializations. Tue Mar 25 10:01:05 1997 Chris Cleeland * config-linux.h: Added ACE_HAS_{SVR4_DYNAMIC_LINKING,AUTOMATIC_INIT_FINI}. Thanks to alex@aureus.sublink.org (Sandro Doro) for the change. * platform_linux.GNU: Added -ldl to LIBS. Thanks to alex@aureus.sublink.org (Sandro Doro) for the change. Tue Mar 25 16:01:34 1997 Carlos O'Ryan * ace/Svc_Handler.cpp: I forgot to comment this: "operator delete" used to call ::delete on a void*, on ANSI/C++ this is not allowed. Since "operator new" calls ::new for a char[] I do a casting to char* and call ::delete[] on the char pointer. * ace/config-hpux-10.x-aCC.h: HP-UX 10.10 supports CLOCK_GETTIME, my guess is that it should work with g++ and HP/C++, but I won't mess with those files yet. * ace/Connector.h: The default address parameter for "connect" is a bit tricky, from the comments in the file: // // If the compiler supports 'typename' we cannot use // // PEER_CONNECTOR::PEER_ADDR::sap_any // // because PEER_CONNECTOR::PEER_ADDR is not considered a // type. But: // // typename PEER_CONNECTOR::PEER_ADDR::sap_any // // will not work either, because now we are declaring sap_any a // type, further: // // (typename PEER_CONNECTOR::PEER_ADDR)::sap_any // // is considered a casting expression. All I can think of is // using a typedef, I tried PEER_ADDR but that was a source of // trouble on some platforms. I will try: // typedef ACE_PEER_CONNECTOR_ADDR ACE_PEER_ADDR_TYPEDEF; * ace/OS.h: The stock HP C++ compiler (cfront based) gives lots of warnings in . I used to define volatile to avoid this warnings. Now I think I'll rather like to see them. * ace/SPIPE_Stream.h: * ace/SPIPE_Connector.h: There was no meta-type info (PEER_ADDR) for SPIPE_Stream and SPIPE_Connector. * ace/Stream_Modules.h: * ace/Stream_Modules.cpp: Fixed a "bug" introduced in my last change: a couple of ACE_ALLOC_HOOK_* were commented but shouldn't. * examples/Connection/non-blocking/CPP-acceptor.cpp (open): PR_AD cannot be used in this context, it expands to _ACE_PEER_ACCEPTOR::PEER_ADDR (via ACE_PEER_ACCEPTOR_ADDR), but the template parameter is _ACE_PEER_STREAM (aka PR_ST_1, aka ACE_PEER_STREAM_1). The right macro was ACE_PEER_STREAM_ADDR. * ace/Connector.h: * ace/Connector.cpp: The typedef trick I used (PEER_ADDR) did not work on every platform. I also broke some examples since ACE_PEER_CONNECTOR_ADDR did not include ACE_TYPENAME on its definition. Hopefully this new trick will work everywhere. * I finally sorted out the mistery of including "ace/Module.h" into "ace/Task_T.cpp": when compiling "ace/Stream_Modules.cpp" you get the following include sequence: Stream_Modules.cpp Stream_Modules.h Task.h Task.i Task_T.h Message_Queue.h (descendants removed) Synch_T.h (descendants removed) Task.h (already included). Task_T.i Task_T.cpp Module.h ACE.h (descendants removed) Task.h (already included). Module.i Module.cpp At this point Module.cpp uses ACE_Thru_Task declared on Stream_Modules.h, but after the #include "ace/Task.h"; in fact Module.cpp tries to #include "ace/Stream_Modules.cpp" but that second #include expands to nothing due to the canonical protection on Stream_Modules.h. That explains the removal of Module.h in Task_T.cpp. If you are wondering why so long an explanation for this change the answer is simple: just because I was curious on now it worked. Mon Mar 24 14:08:48 1997 Douglas C. Schmidt * ace/SOCK_Dgram_Bcast.cpp (mk_broadcast): Cleaned up the code a bit. * ace/ACE: Added a new method called get_bcast_addr() which will get the broadcast address for a host. Thanks to Paul Han for suggesting this. * ace/UNIX_Addr: Added another set method in UNIX_Addr class: void set (const ACE_UNIX_Addr &sa); // Creates an ACE_UNIX_Addr from another . Thanks to Paul Han for this. * ace/SOCK_Dgram: Removed the #if defined (ACE_HAS_IP_MULTICAST) since this is now handled at the ACE_OS level. * ace/OS.h: Added support for IP multicast macros and structs even on platforms that don't support it so that the tests will compile without having lots of #ifdefs. * tests/Future_Test.cpp: Added a check for platforms that lack threads. Thanks to Hakan Kallberg for reporting this. * netsvcs/lib/Server_Logging_Handler.cpp: Added a check for platforms that lack threads. Thanks to Hakan Kallberg for reporting this. * examples/Threads/context_switch_time.cpp: Added an #ifdef for ACE_HAS_THREADS to this test so that it will compile on platforms that don't have threading. Thanks to Scott Halstead for reporting this. * tests/IOStream_Test.cpp: Fixed up this test so that it works correctly on platforms that lack multi-threading. Thanks to Scott Halstead for reporting this. * netsvcs/lib/Makefile: Reincluded the LIB target so that we'll build a static library. Thanks to Scott Halstead for reporting this. * ace/SOCK_Dgram.cpp (recv): Added a check to make sure that we don't try to copy more into the recv buffer than we've really got. Thanks to Alan_Cabrera@fp.cibc.com for this fix. * ace/OS.cpp (readv): Added a check to make sure that we don't try to copy more into the recv buffer than we've really got. Thanks to Alan_Cabrera@fp.cibc.com for this fix. * ace/Malloc.h: Modified the alignment strategy to define ACE_MALLOC_ALIGN to a number of bytes. (it gets rounded to a number of long's). This makes it easier to work with more complex buffer alignment strategies (e.g., DMA). Thanks to Fred LaBar for this. * ace/OS.cpp (readv): Added several more changes for the readv() emulation. Thanks to Alan Cabrera and Adam Porter for these fixes. Mon Mar 24 14:22:17 1997 David L. Levine * ace/OS.cpp (thr_create): For VxWorks, fixed call to ::taskSpawn (). ACE's arguments are in an array, not individual arguments. Also, set flags to VX_FP_TASK if it's 0, to match behavior of ::sp (). Thanks to Dave Mayerhoefer for reporting these and providing the fix. * ace/High_Res_Timer.cpp (elapsed_time (struct timespec &): fixed, using same approach as in elapsed_time (ACE_hrtime_t &nanoseconds), to get nanosecond resolution. * netsvcs/lib/TS_Clerk_Handler.cpp (handle_close): added ACE_UNUSED_ARG (mask). Also, added template specializations. * examples/Reactor/Multicast/server.cpp (Server_Events ctor): rearranged initializers to match declaration order. * examples/IOStream/server/iostream_server.cpp, client/iostream_client.cpp: added template specializations. Mon Mar 24 13:21:31 1997 Tim H. Harrison * ace/High_Res_Timer.cpp (elapsed_time): Added an ACE_High_Res_Timer::elapsed_time (ACE_hrtime_t &nanosecond) method that returns the number of elapsed nanoseconds. This is accomplished even with the scale factors converting to microseconds. It also does not use floating point calculations. Sun Mar 23 13:25:39 1997 Tim H. Harrison * ace/High_Res_Timer.h: Removed from the constructor of High_Res_Timer. All High_Res_Timers now use global_scale_factor_ directly. Hopefully, this will not break any existing code! Sat Mar 22 12:06:22 1997 Douglas C. Schmidt * ace/OS.h: The include statement for config.h was too low. Some defines for key_t, needed for NT, didn't work. Thanks to Alan Cabrera for these fixes. * examples/Reactor/Multicast: Improved the multicast client and server programs to work better. * ace/Connector.cpp: Modified the ACE_Connector::handle_close() method to prevent recursive calls to itself. Thanks to Paul Han for reporting this. * ace/Svc_Handler.cpp: Put the check (closing_ == 0) in the destructor as well as in the destroy() method. This prevents a possible core dump when the timer exists. The instruction reactor::remove_handler in the shutdown method currently will be called twice when ACE_Svc_Handler object is being deleted. Core dump occurs when it tries to execute ACE_Reactor::remove_handler method the second time because the ACE_Svc_Handler object pointer has already been deleted by the previous instruction ACE_Reactor::cancel_timer. Thanks to Paul Han for reporting this. * ace/OS.cpp: Added new thread-safe implementations of writev() and readv() for platforms that lack these functions. * ace/SOCK_Dgram.cpp: Added new implementations of ACE_SOCK_Dgram::{send,recv} that define methods for send(iovec[], ...) and recv(iovec[], ...) for systems that don't have sendmsg() and recvmsg(). Thanks to Alan Cabrera for these fixes. * apps/jaws/HTTP_Handler.cpp: Removed some problematic template specializations that were left over from an earlier version of JAWS. Thanks to Adam Porter for reporting this. * examples/Logger/Acceptor-server/server_loggerd.cpp: Revised the code to use the new ACE_Svc_Handler logic that checks to ensure that we don't recurse infinitely in handle_close(). Thanks to Jean-Marc Strauss for reporting this problem. * examples/Logger/simple-server/Logging_Handler.cpp (handle_close): Added a check to make sure we don't end up recursively calling handle_close(). This will prevent a segfault. Sat Mar 22 07:30:49 1997 David L. Levine * ace/High_Res_Timer.*: Changed scale factor to convert platform-dependent clock units to microseconds instead of nanoseconds. That way, it should be greater than 1 for all supported platforms. So, it's now an unsigned long instead of a double. * ace/OS.h: Changed ACE_hrtime_t to unsigned __int64 with _MSC_VER. Also, fixed typo: "uint64" instead of "unit64" without _MSC_VER. Fri Mar 21 08:37:34 1997 Carlos O'Ryan * makeinclude/rules.lib.GNU: I use the macro SOEXT to support HP non-standard extension for shared library names (.sl instead of .so). I also changed the rule to build shared libraries: under HP-UX you cannot pass extra libraries (-lXXX options) when building a shared lib. Before HP-UX 10.10 it wasn't a problem because no library was needed with ACE, but to support XLI the '-lxti' flag must be used on binaries (but not on shared libs). * include/makeinclude/platform_hpux.GNU: The PIC option (+Z) was used always, clearly not intended. * include/makeinclude/platform_hpux_gcc.GNU: Added a config file for g++ under HP-UX. * include/makeinclude/platform_hpux_aCC.GNU: Added a config file for HP/aCC compiler under HP-UX. * ace/Makefile: * netsvcs/lib/Makefile: Changed to support the SOEXT macro. * config-hpux-10.x.h: * config-hpux-10.x-aCC.h: * config-hpux-10.x-g++.h: I updated the files to HP-UX 10.10, AFAIK since that version HP-UX uses fd_set instead of int in select(2) (so ACE_SELECT_USES_INT is not needed) and the OS supports siginfo_t and ucontext_t so ACE_HAS_SIGINFO_T and ACE_HAS_UCONTEXT_T are defined. I *do not* have threads at my site nor the infamous PHSS_6246 patch so I couldn't test the threaded version nor the HP cfront based one. ACE compiled fine with g++ and HP/aCC though. * ace/OS.h: * ace/Malloc_T.h: HP/aCC supports the typename keyword. I added a new config macro 'ACE_HAS_TYPENAME_KEYWORD', when it is defined ACE_TYPENAME expands to 'typename' when not it expands to nothing. On the cases where HP/aCC requires the usage of 'typename' I added a 'ACE_TYPENAME'. * ace/OS.i: * ace/OS.cpp: ACE_OS::inet_aton cannot be inlined under HP-UX. * ace/Connector.h: * ace/Connector.cpp: I have decided to use a typedef (PEER_ADDR) instead of ACE_PEER_CONNECTOR_ADDR, mainly because the second form requires a ACE_TYPENAME before each usage. * ace/Event_Handler_T.i: Much to my surprize ACE_TYPENAME is required when using a template typedef as a return value. * ace/Local_Name_Space_T.h: HP/aCC does not like the usage of a private typedef from another class. * ace/Strategies_T.h: * ace/Strategies_T.cpp: ACE_Process_Strategy declared two defaults constructors: ACE_Process_Strategy(void) and ACE_Process_Strategy(int = 1). The constructor code was wrong, it called open() with parameters: open(thr_mgr, thr_flags, n_threads) none of which were defined, worse, open() receives just one parameter (the number of processes) just as the constructor, I believe that C-w programming is lurking here. * ace/Signal.cpp: Though the header file does not declare ACE_Sig_Handlers under HP-UX (and the code is not defined too) some auxiliary functions that use ACE_Sig_Handlers were defined. I removed their definition. Some day I'll try to take a look at the code, trying to find out was wrong with them. * ace/Stream_Modules.h: * ace/Stream_Modules.cpp: By mistake I commented out the ACE_ALLOC_HOOK_* macros; have to fix it *real soon*. * ace/Task_T.cpp: No need to include "ace/Module.h" since only the template declaration is used. When ACE_TEMPLATES_REQUIRE_SOURCE is defined you end up using ACE_Thru_Task before it gets defined. This is no problem unless your compiler checks template sintax before instantiation as the HP/aCC compiler do. * examples/Reactor/Misc/test_demuxing.cpp: ACE_MT_SYNCH was used, but it is only defined if ACE_HAS_THREADS, I used ACE_SYNCH instead, which is defined as ACE_MT_SYNCH if ACE_HAS_THREADS and as ACE_NULL_SYNCH if not. Maybe the semantics are wrong, but the thing compiles. Fri Mar 21 15:10:59 1997 Douglas C. Schmidt * ace/Makefile (FILES): Moved Log_Msg to the beginning of the source list in the ace Makefile. This is nice because it forces the compilation of OS.i and that, obviously, is where you get the complaints for the port. It's nice to have it at the beginning so you catch the errors very early on before you've compiled 30 or 40 files. Thanks to Scott Halstead for this suggestion. * ace/Memory_Pool.cpp: Added #if !defined (ACE_LACKS_SYSV_SHMEM) to handle systems like Chorus that lack this feature. Thu Mar 20 18:58:50 1997 Douglas C. Schmidt * ace/Svc_Handler.cpp (destroy): Added a state variable to keep track of when we are closing down the Svc_Handler. This is necessary to prevent endless recursive calls to handle_close() due to the recent enhancements to ACE_Timer_{List,Heap}. Thanks to Bert Craytor for reporting this. * tests/Conn_Test.cpp: Added a new test that makes sure the Acceptor, Connector, and Svc_Handler are working correctly. * ace: Added some more changes for Chorus. Thanks to Wei Chiang for these changes. * ace/OS.h: Added #define for SIGSEGV for platforms that lack it (e.g., Chorus). * ace: Made a bunch of minor changes to support SunOS 4.x better. Thanks to Scott Halstead for reporting these problems. * tests/Conn_Test.cpp: Added ACE_TEMPLATES_REQUIRE_SPECIALIZATION for the various templates used in this test. Thanks to Thilo Kielmann for reporting this. * ace/Connector.cpp (connector): Fixed some minor bugs that prevented the ACE_Connector from compiling. Thanks to David Levine for noticing this. * ace/OS.h: Moved the ACE_LACKS_SIGACTION block so that it will work on Win32. Thanks to Matthias Kerkhoff for pointing this out. Thu Mar 20 22:38:27 1997 David L. Levine * ace/Timer_Heap.cpp: added template specializations. * netsvcs/lib/Client_Logging_Handler.cpp, Name_Handler.cpp Server_Logging_Handler.cpp TS_Clerk_Handler.cpp TS_Server_Handler.cpp Token_Handler.cpp: added template specializations. There are still many missing from libnetsvcs. * tests/Conn_Test.cpp, Future_Test.cpp IOStream_Test.cpp Map_Manager_Test.cpp Message_Block_Test.cpp Message_Queue_Test.cpp Reader_Writer_Test.cpp SV_Shared_Memory_Test.cpp Thread_Pool_Test.cpp}: added template specializations. Thanks to Thilo Kielmann for providing these. * ace/Log_Msg.cpp: removed commented-out template specialization. * include/makeinclude/platform_{chorus,hpux,hpux_gcc}.GNU: split out CFLAGS and CCFLAGS from CC and CXX. * ace/config-aix-4.[12].x.h: added back ACE_HAS_THREAD_SELF and and ACE_HAS_SVR4_DYNAMIC_LINKING; removed ACE_HAS_PTHREAD_T. Thanks to Chris Lahey for figuring these out. Thu Mar 20 12:25:30 1997 * ace/ace.{mak,mdp}: Build->Settings->Code Generation->Processor is now set to "Pentium" instead of "Blend*" for Debug and Release builds. * ace/config-win32-msvc4.x.h: * ace/config-win32-msvc2.0.h: * ace/config-winnt-4.0-msvc4.x.h: Only define ACE_HAS_PENTIUM when _M_IX86 == 500. Projects must specify Pentium in Build->Settings->Code Generation->Processor to use the RDTSC instruction in ACE_OS::gethrtime. * ace/High_Res_Timer.{cpp,i}: By default, High_Res_Timer is constructed with a scale_factor == 1. This allowed me to remove all the checks for scale_factor == 0 in the code. * ace/High_Res_Timer.h (static gettimeofday): If global_scale_factor_ is not set, and we're on a platform that requires global_scale_factor_ (e.g., Win32), ACE_OS::gettimeofday will be used instead of ACE_OS::gethrtime. This allows the scale_factor of 1 to still result in correct values. Wed Mar 19 15:02:09 1997 Douglas C. Schmidt * ace: Added zillions of minor changes so that ACE will compile on the new aCC compiler for HPUX. Thanks to Gonzalo A. Diethelm and Carlos O'Ryan for help with this. * ace/SOCK_Dgram_Mcast.cpp (subscribe): In addition to the SO_REUSEADDR option, Irix has a SO_REUSEPORT option that must also be set to allow multiple sockets to bind to the same multicast address. Thanks to Robert V. Head for reporting this. * ace: Added a slew of changes to support CHORUS. Thanks to Wei Chiang for these changes. * ace/config-sunos4.*.h: Added #define ACE_HAS_UNION_WAIT based on the recommendation of Kumar Neelakantan . * ace/Log_Msg.cpp (log_hexdump): Replaced the use of ::sprintf() with ACE_OS::sprintf() so that the return value would be correct on SunOS 4.x! * ace/OS: Added ACE_HAS_CHARPTR_SPRINTF and ACE_SPRINTF_ADAPTER to ACE_OS::sprintf() for SunOS 4.x platforms. Thanks to Kumar Neelakantan for reporting this. * ace/Handle_Set.cpp (ACE_Handle_Set_Iterator): If the bound was reached in the following loop, we should set this->num_ = this->handles_.max_handle_ + 1 rather than go into the 2nd loop. Thanks to Michael Newton for reporting this. * ace/Handle_Set.cpp (ACE_Handle_Set_Iterator): ACE_Handle_Set_Iterator::ACE_Handle_Set_Iterator did not work properly if called with a zero handleset, as there was no bounds check on the first loop therein. Thanks to Michael Newton for reporting this. Wed Mar 19 16:06:32 1997 David L. Levine * ace/OS.h,README: added ACE_HAS_AIX_BROKEN_SOCKET_HEADER to wrap #include of sys/socket.h with #undef/#define of __cplusplus. * ace/config-aix-4.[12].x.h: added ACE_HAS_AIX_BROKEN_SOCKET_HEADER, ACE_HAS_PTHREAD_T, ACE_LACKS_TCP_H, and ACE_LACKS_SETSCHED. Removed ACE_HAS_SVR4_DYNAMIC_LINKING and ACE_HAS_THREAD_SELF. Thanks to Daniel Montalibet for both of the above modifications. * platform_{dgux4_epc,irix5.3_g++,linux*,m88k,osf1_3.2,sco*, sunos4_g++,sunos5_centerline*,sunos5_g++,sunos5_sunc++*, unixware_g++,vxworks5.2_g++}.GNU: split out CFLAGS and CCFLAGS. Also, removed -lstdc++/-lm from g++ versions, because we now set CXX to g++ instead of gcc, so those libraries are picked up. * include/makeinclude/platform_osf1_4.0{,_g++}.GNU: added -lrt to support ACE_Sched_Params. Thanks to Thilo Kielmann for suggesting this. Also, split out CFLAGS and CCFLAGS. * ace/OS.h: removed SVR4_DYNAMIC_LINKING protection around #define of RTLD_LAZY because it's used in ace/Parse_Node.cpp. Thanks to Matthias Kerkhoff for pointing this out. * ace/OS.i (thr_setcanceltype): added ACE_UNUSED_ARGS for STHREADS case. Thanks to Chuck Gehr for providing this fix. Tue Mar 18 21:53:03 1997 Douglas C. Schmidt * ace/SOCK_Dgram_Bcast.cpp (mk_broadcast): Modified the SOCK_Dgram_Bcast class by adding a const char *host_name to the contructor, and open, and mk_broadcast methods. If the user passes in the host_name, then only the broadcast address of an interface that has a matching ip address with the host will be added to the if_list_. Otherwise, nothing changes. Thanks to Paul for this feature. Tue Mar 18 13:20:59 1997 Irfan Pyarali * ace/ace.mdp: Reverted the change for DllMain as the entry point to ace.dll. This is causing problems in multi-threaded applications. * netsvcs/lib/Client_Logging_Handler.cpp: Added a check in fini() to make sure we have a valid handler. If the connect attempt failed, this->handler_ will be set to 0. * tests/Mem_Map_Test.cpp: Added code that removes all temporary files created by the test. * tests/Time_Service_Test.cpp: Made sure we remove the backing store file left behind by a aborted clerk process. * examples/Reactor/Ntalker/ntalker.cpp: The ntalker now uses ACE::register_stdin_handler to register the STDIN. This function allows for portability. Tue Mar 18 08:12:22 1997 David L. Levine * ace/Svc_Conf_y.cpp,Makefile: replaced "y.tab.c" string with "Svc_Conf_y.cpp" to ease debugging. Thanks to Luca Priorelli for suggesting this. * ace/IOStream.cpp (close): replaced call to ACE_SOCK_Stream::close () with one to generic STREAM::close (). Thanks to Kumar Neelakantan for reporting this problem. * ace/OS.h,README,config-*.h: removed ACE_HAS_RTLD_LAZY_V, and replaced with #define of RTLD_LAZY macro only if it's not already defined (and if ACE_HAS_SVR4_DYNAMIC_LINKING is defined). Thanks to Chris Lahey for providing this fix. * ace/OS.i (thr_setcancelstate, thr_setcanceltype, thr_cancel): added ACE_UNUSED_ARG calls to avoid compiler warnings. Thanks to Chuck Gehr for suggesting them. * ace/Local_Name_Space_T.h: moved #include of Local_Name_Space.h up because this file needs declaration of ACE_NS_String. There _shouldn't_ be a circular include problem because the #includes are protected. Thanks to Daniel Montalibet for reporting this problem and providing the fix. * ace/Local_Name_Space.h: removed #include of ace/Service_Config.h. * include/makeinclude/wrapper_macros.GNU: put -I. before -I$(WRAPPER_ROOT) instead of after. * tests/IOStream_test.cpp: added checks for receipt of proper values. Tue Mar 18 01:38:14 1997 Irfan Pyarali * ace/ace.mdp: Add DllMain as the entry point of ace.dll. This allows us to call WSAStartup when ace.dll is loaded in and WSACleanup when ace.dll is unloaded. People using ace as a static library are still out in the cold with respect of getting WSACleanup called before the process exits. I am not sure of two cases: (1) What happens when an application crashes and was not able to call WSACleanup and (2) if the application wants to continue using sockets when ace.dll is unloaded. I hope this solves more problems than it creates ;-) Tue Mar 18 01:38:14 1997 Irfan Pyarali * ace/Parse_Node.cpp: Added END_OF_LINE characters to some ACE_ERRORs. * netsvcs/{lib,servers}: Fixed the project files to produce and use the dll in the correct place (which is netsvcs/lib). * ace/Log_Record.cpp: Corrected format string for fprintf(). * examples/Threads/test.mdp: Added context_switch_time.cpp to the project. All of the above bugs were reported by Luca Priorelli . Thanks for the contribution. Mon Mar 17 12:59:56 1997 David L. Levine * ace/OS.{h,i}: added nanosleep (), currently supported only on POSIX platforms (if ACE_HAS_CLOCK_GETTIME is defined). * examples/Mem_Map/IO-tests/{IO_Test.cpp,test_io.cpp): LM_ERROR instead of ACE_ERROR, and fixed call to ACE::basename (). * ace/OS.cpp (sched_params): return -1 if not supported, instead of ENOTSUP. * ace/OS.cpp (fork): added ACE_UNUSED_ARG (program_name) for WIN32 and VxWorks. * ace/Sched_Params.cpp (priority_min, priority_max, next_priority, previous_priority): not supported on MVS, via ACE_LACKS_SETSCHED. Thanks to Chuck Gehr for figuring this out and providing the fix. * tests/Timer_Queue_Test.cpp (test_performance): changed type of local variable "i" to (signed) int to avoid signed/unsigned comparison, and eventual seg fault because a loop would never terminate. Sun Mar 16 11:31:46 1997 Douglas C. Schmidt * ace/Timer_{List,Queue,Heap}.h: Defined copy constructors and assignment operators in the private part of the class so that users won't accidentally make mistakes. Sat Mar 15 21:44:45 1997 Douglas C. Schmidt * ace/Timer_{Queue,List}.cpp (cancel): handle_close() should be called only once (especially when handle_close() implements "delete this;" ). Since it is possible that the EH will be registered more than once, I changed the code to do the following: if (number_of_cancellations == 1) // Call the close hook. curr->handler_->handle_close (ACE_INVALID_HANDLE, ACE_Event_Handler::TIMER_MASK); Thanks to Hamutal Yanay for suggesting this. * examples/Mem_Map/IO-tests/test_io.cpp (run_tests): Removed all uses of ::perror and replaced them with calls to ACE_ERROR macros. * ace/Mem_Map.i (unmap): The ACE_Mem_Map::close method does not work properly if the value of file_mapping_ is equal to ACE_INVALID_HANDLE. In this case the method calls a useless close (-1). Therefore, I changed: if (this->file_mapping_ != this->handle_) ACE_OS::close (this->file_mapping_); in: if (this->file_mapping_ != this->handle_ && this->file_mapping_ != ACE_INVALID_HANDLE) ACE_OS::close (this->file_mapping_); Thanks to Sandro Doro for reporting this. Thu Mar 13 18:21:15 1997 Irfan Pyarali * ace/ReactorEx.h: Change protection of methods/variables of ReactorEx from private to protected. Thanks to Matthias Kerkhoff for suggesting this. Thu Mar 13 16:31:54 1997 David L. Levine * ace/OS.i (thr_getprio): Added missing ACE_NOTSUP_RETURN for the case of pthreads && !defined (ACE_LACKS_SETSCHED). Thanks to Chuck Gehr for reporting this. Thu Mar 13 00:12:15 1997 Irfan Pyarali * ace/Local_Name_Space_T.cpp (dump): Added ACE_UNUSED_ARG around fake_this to stop the compiler from complaining about unused variables. * ace/Message_Block.cpp (ACE_Data_Block::size): Moved the copying of the old base before freeing it up. Thanks to Dieter Quehl (dietrich.quehl@med.siemens.de) for pointing this out. * ace/Local_Name_Space_T.cpp: Added code to the list methods such that structured exceptions are handled correctly. Thanks to Karlheinz Dorn (karlheinz.dorn@med.siemens.de) for reporting this. Wed Mar 12 21:31:51 1997 Irfan Pyarali * examples/Reactor/Ntalker/ntalker.cpp: Made changes to the program which allows it to run under Win32. * ace/SOCK_Dgram_Mcast.cpp: Made changes to the setting of the interface address so that it works correctly under Win32. Thanks to Todd L. Montgomery (tmont@cs.wvu.edu), Anton van Straaten (anton@appsolutions.com), Ole O. Johnsen (Ole.Johnsen@gpi.telemax.no), Mike Flinn (mike.flinn@smtpgate.aws.waii.com), Steve Weismuller (spweismu@rsoc.rockwell.com) and others who helped out. Wed Mar 12 17:05:52 1997 Chris Cleeland * ace/config-linux-lxpthreads.h: Added ACE_HAS_IP_MULTICAST. Wed Mar 12 16:07:07 1997 David L. Levine * ace/OS.i (gethrtime): Added support for VxWorks and other platforms that support ACE_HAS_CLOCK_GETTIME. Tue Mar 11 21:38:42 1997 Irfan Pyarali * ace/OS.i (open): Improved support for passing flags through to CreateFile (). Tue Mar 11 14:30:12 1997 David L. Levine * ace/config-vxworks-ghs-1.8.h: added ACE_LACKS_SYS_NERR. Thanks to Dave Mayerhoefer for reporting this. * ace/OS.{i,cpp} (uname, hostname): added VxWorks support. Thanks to Dave Mayerhoefer for providing this. (Also, uninlined ACE_OS::uname on WIN32 and VxWorks because it contains string literals.) * ace/High_Res_Timer.{i,cpp}: fixed interpretation of units: ACE_hrtime_t is in nanoseconds, so it should be divided by 1000000000 to get seconds. Fixed divs/mods to first divide by 1000, then div/mod. Thanks to Luca Priorelli for identifying this problem. Also, removed some casts that are no longer necessary, and added some casts of ACE_hrtime_t values to longs to avoid compiler warnings. Thanks to Matthias Kerkhoff for pointing this out. * ace/Reactor.cpp (unbind): cast "index" to int to avoid signed/unsigned comparison. Thanks to Matthias Kerkhoff for pointing this out. * ace/ReactorEx.cpp (bind): changed type of "current_size" to size_t to avoid signed/unsigned comparison. Thanks to Matthias Kerkhoff for pointing this out. * ace/Timer_Heap.cpp (ctor, grow_heap): cast unsigned value (i + 1) to int before negating to avoid compiler warning. Thanks to Matthias Kerkhoff for pointing this out. * examples/Threads/context_switch_time.cpp (main): added ACE_SCOPE_PROCESS param to ACE_Sched_Params instances so that the test works on WIN32. Thanks to Luca Priorelli for identifying this problem. * ace/Registry.{h,cpp},Registry_Name_Space.{h,cpp},Svc_Conf_Tokens.h, Svc_Conf_{l,y}.cpp,Timer_{Heap,List}.cpp,config-aix-4.2.x.h, config-dgux-4.11-epc.h,config-mvs.h,config-sco-5.0.0-fsu-pthread.h, config-sco-5.0.0-mit-pthread.h,config-sco-5.0.0-nothread.h: added CVS header (Id wrapped in $). * netsvcs/clients/Logger/indirect_logging.cpp (main): declare loop index as signed int to avoid signed/unsigned comparison. Tue Mar 11 07:34:04 1997 Douglas C. Schmidt * tests/Timer_Queue_Test.cpp: Added some code to illustrate how the new handle_close() hook for ACE_Timer_{Heap,List} work. * ace/Timer_Heap.cpp (cancel): Modified the Timer_Heap and Timer_Queue so that it will call the handle_close() hook when Event_Handler's are cancelled. This is necessary to reclaim resources. Thanks to Hamutal Yanay for suggesting this. * ace/Event_Handler.h (signal): Added a TIMER_MASK, which is passed to handle_close() when a timer is cancelled. * ace/Log_Msg.cpp (log): Fixed a bug by setting LPTSTR lpMsgBuf = 0 on line 524. Thanks to Mark Wright for reporting this. Sun Mar 10 13:06:04 1997 Douglas C. Schmidt * examples/Mem_Map/IO-tests: Fixed a small bug in "IO_Test.cpp" file. In the "int Mmap1_Test::run_test" method I inserted an lseek to rewind the output file. With this correction the speed go up due to IO cache. Thanks to Sandro Doro for reporting this. Sun Mar 9 18:24:37 1997 Prashant Jain * java/src/IOCntlMsg.java (IOCntlMsg): Added two new classes/files, namely IOCntlCmds and IOCntlMsg. * java/src/Task.java: Added accessors to get/set the flags of the Task. Sun Mar 9 13:06:04 1997 Douglas C. Schmidt * ace/Reactor: Fixed an evil bug where the expression if (handle >= 0 || handle < this->max_handlep1_) should be if (handle >= 0 && handle < this->max_handlep1_) Thanks to Mark Wright for reporting this. Sun Mar 9 13:06:04 1997 Douglas C. Schmidt * apps/Gateway: Updated the Peer and Gateway applications so that they don't try to register ACE_STDIN with the Reactor on Win32. * apps/Gateway: Changed a bunch of calls to ACE_Reactor::remove_handler() so that it no longer tries to remove descriptor 0, but instead uses ACE_STDIN. Naturally, this doesn't work due to the way that Win32 implements select() but at least it compiles... Thanks to Elliot Lau for reporting this. * apps/Gateway/Gateway/File_Parser: Changed the enumerated type ERROR to PARSE_ERROR to avoid a name clash with a symbol reserved by Win32 (barf). Thanks to Elliot Lau for reporting this. Sat Mar 8 12:37:44 1997 Douglas C. Schmidt * ace/Log_Msg.cpp: Changed the implementation of ACE_Log_Msg so that all accesses to the lock_ are now through a Singleton. This makes it possible to define multiple instances of ACE_Log_Msg within the same thread. Thanks to Jeff Morgan for helping track this down. * Added support for SCO 5.0. Thanks to Auturo for these patches. Thu Mar 06 13:24:04 1997 David L. Levine * ace/OS.i (gettimeofday): moved declaration of "result" so that it's not declared on VxWorks, where it's not needed; (stat): added cast of file arg to char * for VxWorks; (thr_getprio): added missing "#else" before ACE_NOTSUP_RETURN (-1). Thanks to Dave Mayerhoefer for reporting these. * ace/OS.cpp (sched_param): with STHREADS, map ACE_SCOPE_THREAD to ACE_SCOPE_PROCESS'. * ace/Svc_Conf_l.cpp: commented out YY_BREAK after ace_yyterminate () to avoid GHS compiler warning about unreachable statement. Thanks to Dave Mayerhoefer for reporting this. * ace/ace.mak: removed Thread_Priority and renamed Scheduling_Params to Sched_Param. * examples/IPC_SAP/SOCK_SAP/FD-unserver.cpp (handle_client): added "l" qualifier for sprintf of ACE_OS::getpid (). * tests/Priority_Task_Test.cpp, examples/Threads/{context_switch_time.cpp,Makefile}: adapted to new thread priority/ACE_Sched_Params. Wed Mar 5 14:33:04 1997 Douglas C. Schmidt * ace/UNIX_Addr.cpp: Enhanced the implementation of set() so that it works correctly on MVS, which has a different definition of struct sockaddr_un: struct sockaddr_un { unsigned char sun_len; unsigned char sun_family; char sun_path[108]; }; Thanks to Chuck Gehr for reporting this. Wed Mar 05 14:47:14 1997 David L. Levine * ace/OS.{h,cpp},Makefile; also, renamed Scheduling_Params.* to Sched_Params.* and removed Thread_Priority.*: Major change in scheduling parameters interface: The key change is that there is no longer a special thread priority enum. Thread_Priority was changed to int, so applications can do whatever they want. The ACE_Sched_Params class has some static functions to help do this portably. Here are the changes from the ACE 4.1.3: 1) ACE_Thread_Priority: removed this class. It contained "priority class" and "thread priority". "Priority class" is platform-specific and doesn't need to be visible in ACE; it is subsumed by scheduling policy, see below. "Thread priority" is replaced by the global ACE_Sched_Priority typedef in ace/OS.h, see next change. 2) ace/OS.h: added ACE_Sched_Priority typedef (to int) and ACE_SCOPE_THREAD. 3) ace/OS.h: added scheduling policy #defines: ACE_SCHED_OTHER, ACE_SCHED_FIFO, and ACE_SCHED_RR. There's an ACE_Sched_Params:: Policy typedef that can take one of these values. 4) ACE_Sched_Params: added priority_min (), priority_max (), next_priority (), and previous_priority () functions. All require an ACE_Sched_Params::Policy argument and take an optional scope argument (to support the distinct thread and process priorities on DEC UNIX). min_priority () and max_priority () have platform-specific and policy-specific values, and direction (the min value may be higher than the max value). The increment and decrement operations allow applications to iterate over them, etc., without explicitly specifying the direction of the priority (0 for high or low priority). 5) The only way to apply ACE_Sched_Params is through ACE_OS::sched_params (const ACE_Sched_Params &). (This is not really a change, except for the name change from ACE_OS::set_sched_params (). It sets both policy and priority of current thread or process (depending on the scope in ACE_Sched_Params). Not all combinations of policy, priority, and scope are legal on all platforms. Unfortunately, I see no way around this, because the intersection of legal ranges on our supported platforms is empty. If an illegal request is made, ACE_OS::sched_params () sets errno to EINVAL and returns -1. 6) added ACE_OS::thr_setprio (const ACE_Sched_Priority prio) to set the current thread's priority, only. Many thanks to Thilo Kielmann for his careful review of this class design, thoughtful comments, and assistance with implementation, especially for PTHREADS platforms. Wed Mar 5 14:36:59 1997 Irfan Pyarali * SString.cpp: Fixed ACE*String initialization bugs. Thanks to jmorey@tbi.com (John Morey) for reporting this. Wed Mar 5 14:33:04 1997 Douglas C. Schmidt * ace/OS.i: Fixed a bug in gethrtime const ACE_Time_Value now = ACE_OS::gettimeofday (void); which should be const ACE_Time_Value now = ACE_OS::gettimeofday (); Thanks to Chuck Gehr for reporting this. Tue Mar 4 16:37:26 1997 Douglas C. Schmidt * examples/IPC_SAP/SOCK_SAP/CPP-unserver.cpp (main): Make life easier by doing an unlink(rendezvous) before reopening the UNIX-domain socket. Thanks to Jeff Morgan for suggesting this. Sun Mar 02 19:58:00 1997 David L. Levine * ace/config*.h: removed #define of ACE_HAS_INLINED_OSCALLS because it's no longer needed in the config files: it's #defined in OS.h if needed. Sun Mar 2 17:14:29 1997 Douglas C. Schmidt * include/makeinclude: Updated all the platform-*g++.GNU files so that they no longer -D__ACE_INLINE__ (since this is handled in the the config-*g++.h files). * ace: Updated all the config-*g++.h files so that they now #define __ACE_INLINE__ rather than having this set in the platform_*.GNU file. This makes ACE easier to build and integrate with other software packages. Fri Feb 28 02:22:33 1997 Douglas C. Schmidt * ace/SOCK_*: There were problems starting UDP broadcast servers (all using the same well known port number) multiple times on one machine (this is very useful test distributed applications on one single machine). Setting the SO_REUSEADDR option for the broadcast socket allows binding of a socket that is already in use and thus allows us to start more than one broadcast servers in parallel on one machine. Thanks to Dieter Quehl for this fix. Therefore, I patched ACE_SOCK_Dgram_Bcast, ACE_SOCK_Dgram and ACE_SOCK to include this feature. In addition, I also changed ACE_SOCK_Connector/ACE_SOCK_Acceptor to use this feature instead of calling setsockopt() there explicitly. * examples/IPC_SAP/SOCK_SAP/FD-unserver.cpp (main): Fixed up the use of ACE_OS::fork() here to use the new "named" version. * ace/OS.h: Added a clever new wrapper function called fork (const char *program_name), which calls fork() and then automatically calls ACE_LOG_MSG->sync (program_name) to sync up the program name. This eliminates a common source of error when forking children and using ACE_Log_Msg::log(). * examples/IPC_SAP/SOCK_SAP/FD-un{client,server}.cpp: Updated the FD client and FD server programs so that it is now a concurrent server. * ace/config-mvs.h: Added #define ACE_LACKS_TCP_H for MVS. Thanks to Chuck Gehr for pointing this out. * ace/OS.h: Added a new #define ACE_LACKS_TCP_H that skips the inclusion of the netinet/tcp.h file if it isn't on the platform. * ace/OS.i (thr_cancel): Changed the line ACE_UNUSED_ARG (t_id); to ACE_UNUSED_ARG (thr_id); Thanks to Chuck Gehr for reporting this. * ace/SString.cpp: Fixed up all the ACE_[CSW]String code so that always allocates a rep_ even in the null constructor. This saves us from having to handle odd special cases later on... Thanks to John Morey for reporting this. * ace/Service_Repository.cpp (close): Changed the order in which services are destroyed when the Service Configurator is closed. Currently, services are destroyed in the order in which they are created according to the svc.conf file. Now, we shut them down in reverse order. This makes more sense when services are related, i.e., one service has to be started before another. Thanks to Karlheinz for this suggestion. Fri Feb 28 12:13:09 1997 David L. Levine * ace/OS.h: fixed definition of ACE_TIMER_SKEW. Thanks to Chuck Gehr for pointing this out. Thu Feb 27 21:36:28 1997 David L. Levine * ace/OS.{i,cpp} (gethrtime): support on all platforms by using ACE_OS::gettimeofday () if there is no native high resolution timer. Moved ACE_OS::getimeofday () definition toward top of OS.i so that it is always defined before being called. Finally, expanded gethrtime () support from linux to __GNUC__ with ACE_HAS_PENTIUM; it should work on platforms such as VxWorks with gcc on Pentiums. * ace/config-osf1-4.0-{,g++}.h: added ACE_HAS_CLOCK_GETTIME. Thanks to Thilo Kielmann for pointing this out. Thu Feb 27 17:06:12 1997 * ace/High_Res_Timer.h (get_env_global_scale_factor): This static method will set the global_scale_factor to the value in an environment variable (ACE_SCALE_FACTOR by default). * ace/High_Res_Timer.*: Changed all calculations to divide by scale_factor before doing / and %. This must be done before the mod for correctness. * ace/Profile_Timer.i (start): Changed start and stop methods to call ACE_High_Res_Timer::gettimeofday. This should allow greater timing accurracy. * ace/High_Res_Timer.h (global_scale_factor): Added a static global_scale_factor that allows applications to set one scale factor for all high res timers. This is important for platforms like intel where the scale factor will vary based on the processor clock speed. * ace/High_Res_Timer.i (gettimeofday): This static method calls ACE_OS::gethrtime and converts to an ACE_Time_Value based on the global_static_factor. Wed Feb 26 18:28:35 1997 Douglas C. Schmidt * ACE-install.sh: Added some fixes for the ACE-install.sh script. Thanks to Eugene R. Somdahl for reporting these. * ace/Connector.cpp (handle_close): Added a test to see if the reactor_ is NULL and if it is, don't bother trying to use it to clean up. Thanks to Paul Han for this suggestion. Tue Feb 25 21:19:57 1997 David L. Levine * ace/OS.h,config-sunos*.h: default ACE_TIMER_SKEW to 0, and override to 10 ms in all Solaris config files. * ace/Svc_Conf_l.cpp,Makefile: #undef ACE_HAS_TERM_IOCTLS so that /usr/include/sys/termios.h won't be included; it #defines ECHO, and Svc_Conf_l.cpp has an ECHO symbol. * ace/ACE.cpp (sock_error): added ACE_UNUSED_ARG (error);. * ace/Timer_Queue.cpp (ctor): rearranged initializers to match declaration order. Tue Feb 25 19:57:54 1997 * ace/Timer_Queue.cpp (gettimeofday): Added gettimeofday accessors on the Timer_Queue. The default implementation calls ACE_OS::gettimeofday. Applications can specify, via pointers to functions, that a timer queue use an alternate gettimeofday implementation (e.g., a high resolution timer). * ace/Reactor.cpp (schedule_timer): The Reactor no longer calls ACE_OS::gettimeofday. Instead, it calls Timer_Queue::gettimeofday. * ace/ReactorEx.cpp (schedule_timer): The ReactorEx no longer calls ACE_OS::gettimeofday. Instead, it calls Timer_Queue::gettimeofday. Tue Feb 25 17:40:57 1997 Douglas C. Schmidt * ace/Log_Msg.cpp: Updated the 'p' option of the log() method to use the new ACE::sock_error() method for cases where FormatMessage() fails. * ace/ACE: Added a new sock_error() method to class ACE which returns the appropriate message for each WinSock error code. This makes up for an apparent oversight in Win32. Thanks to Michael R. MacFaden" for this. Tue Feb 25 01:33:06 1997 Douglas C. Schmidt * ace/OS.h: Moved outside of the VXWORKS #ifdef since it seems to be available on other platforms (e.g., Solaris). If people find this not to be the case on all platforms please let me know and I'll #ifdef it. Thanks to Sumedh Mungee for reporting this. Tue Feb 25 16:20:29 1997 Irfan Pyarali * examples/Connection/non_blocking/CPP-acceptor.cpp: Added a specific checl for timeouts. Also, changed ACE_PEER_ACCEPTOR_ADDR to ACE_PEER_STREAM_ADDR * examples/Connection/non_blocking/non-blocking.{mak,mdp}: New project files for Win32. * ace/Log_Msg.cpp: Minor changes. Mon Feb 24 17:16:06 1997 Douglas C. Schmidt * ace/Log_Msg.cpp (ACE_Log_Msg): Enable the thread-specific tracing flag by default. This ensures that tracing will work "out of the box." * ace/config-sunos5.[45]-g++.h: Added a #define for ACE_HAS_TERM_IOCTLS. Thanks to Joey Zhu for reporting this. * ace/Synch.cpp (acquire): Simplified the recursive mutex logic for acquire(). Thanks to Arthur J. Lewis" for reporting this. * examples/Connection/non_blocking/CPP-acceptor.cpp (init): Added a #ifdef for ACE_WIN32 so that we don't register the signal handler for SIGPIPE since it's not supported on Win32. Thanks to Ivan Murphy for reporting this problem. * examples/Connection/non_blocking: The SPIPE examples in (test_spipe_{acceptor,connector}.cpp) aren't ported to Win32 yet. They currently don't work because ACE_SPIPE*'s can't be registered with the ACE_Reactor (which only works with sockets). I've #ifdef'd these examples so that they don't get compiled on Win32. Thanks to Ivan Murphy for reporting this problem. Mon Feb 24 20:28:10 1997 David L. Levine * ace/OS.h: use signed __int64 for ACE_hrtime_t because VC++ won't convert unsigned __int64 to double. Thanks to Irfan for reporting this. * include/makeinclude/platform_{irix5.3_g++,linux*,m88k, osf1_4.0_g++,sco-nothread,sunos*g++,unixware_g++}.GNU: changed C++ compiler (CXX) from gcc to g++ so that libg++ will be linked in. Thanks to James CE Johnson for suggesting this. * examples/IOStream/{client,server}/Makefile,tests/Makefile: removed -lg++, when gcc is the compiler, because it's no longer needed with g++ as the compiler. Sat Feb 22 23:03:45 1997 David L. Levine * ace/OS.i: restored version 4.89 and 4.90 changes that were lost in version 4.91. * ace/OS.{i,cpp},config-linux*.h: added ACE_OS::gethrtime () support for Linux on Pentiums. * ace/High_Res_Timer.*: changed scale_factor type from u_long to double so that it can be less than 1. * ace/Thread_Priority.cpp: "linux" instead of "LINUX". * tests/Priority_Task_Test.cpp (open): set this->priority_ because an assertion uses it. Also, use ACE_NORMAL_PRIORITY_CLASS so that root doesn't have to run the test on Solaris. Sat Feb 22 22:07:35 1997 Chris Cleeland * tests/Priority_Task_Test.cpp (open): Now use ACE_Thread_Priority while setting the priority of the new thread. * ace/Thread_Priority.cpp (convert_to_os_priority): Changed return type for this to 'int' from 'long' on Linux. Thanks to James CE Johnson for pointing this out! * ace/OS.i (thr_cancel): Corrected erroneous macro argument. Thanks to James CE Johnson for pointing this out! Sat Feb 22 17:00:59 1997 * ace/OS.i (gethrtime): Added support for intel's RDTSC instruction for pentium architectures. Sat Feb 22 10:57:47 1997 Douglas C. Schmidt * ace/Stream.cpp (open): Make sure that if we allocate the Tasks in the Stream head and the Stream tail that we set the M_DELETE flag so that the close() method will clean up the memory. Thanks to David Levine and Purify for noticing this problem. Fri Feb 21 08:06:41 1997 Douglas C. Schmidt * ace/OS.i: Yikes, it looks like the Solaris and the POSIX version of sigwait() are different! The Solaris version returns the signal number, whereas the POSIX version returns 0 on success, errno on failure, and sets a parameter with the signal on success. I've fixed the ACE_OS C++ wrapper so that the right thing happens, i.e., errno is always set to the error (if sigwait() returns -1) and the signum is always returned as the argument and the return value on success ... Thanks to Harry Gunnarsson for reporting this. Fri Feb 21 11:01:22 1997 David L. Levine * ace/Thread_Priority.cpp: fixed return type of convert_to_os_priority () for Linux. Thanks to James CE Johnson for pointing this out. * examples/Shared_Malloc/test_malloc.cpp, examples/System_V_IPC/SV_Message_Queues/{T,}MQ_Server.cpp (main): added ACE_UNUSED_ARG (sa);. Fri Feb 21 04:12:31 1997 * ace/OS.h: Added ACE_SEH_FINALLY. * ace/ReactorEx.h: Added ACE_ReactorEx_Test as a friend class. I think we should have one such friend class for all classes in ACE. * examples/Reactor/ReactorEx/test_exceptions.cpp: New test which checks how ReactorEx deals with structured exceptions thrown by user code * ace/ReactorEx.cpp (safe_dispatch): Added protection against structured exceptions caused by user code when dispatching handles Thu Feb 20 17:32:54 1997 Douglas C. Schmidt * apps/Gateway: Added a new -v flag to the peerd and gatewayd applications so that they will print out the strings that are passed to them. This makes it easier to debug and see what's happening. Wed Feb 19 19:39:06 1997 Douglas C. Schmidt * apps/Gateway/Gateway/Concrete_Proxy_Handlers.cpp (recv): Removed the VERBOSE #ifdefs since they weren't used and were causing compile errors. Thanks to Bert Craytor for reporting this. Wed Feb 19 00:39:50 1997 Douglas C. Schmidt * examples/ASX/Event_Server: Updated the README file a bit to clarify some loose ends. The documentation now explains precisely how to start up the transceivers correctly. Thanks to Patty Genuald for suggesting this. * include/makeinclude: Removed the default symlink for platform_macros.GNU since it is "Solaris-biased" ;-). Thanks to Amos Shapira for reporting this. Wed Feb 19 14:41:18 1997 Tim H. Harrison * ace/Reactor.cpp: Modified to use timer_queue_->gettimeofday(). * ace/Proactor.cpp: Modified to use timer_queue_->gettimeofday(). * ace/ReactorEx.cpp: Modified to use timer_queue_->gettimeofday(). Also had to modify the ReactorEx_Notify mechanism to use the ReactorEx's timer queue to call gettimeofday. * ace/Timer_Queue.h: Added a gettimeofday method. This allows applications to replace the timer mechanism used by the Reactors. The default implementation returns ACE_OS::gettimeofday. However, a real-time application can inherit from Timer_Queue and override gettimeofday to return a value from a high resolution timer. * STL/bool.h: Changed the defines for type bool. First, bool is no longer defined for WIN32 since yvals.h typedefs it already. Also, I moved the defines out the namespace. I'm not sure if that's the right thing to do. Tue Feb 18 16:41:02 1997 Douglas C. Schmidt * include/makeinclude: Added minor enhancements to rules.local.GNU and wrapper_macros.GNU so that it works with MVS. Thanks to Chuck Gehr for this. * include/makeinclude: Added a new platform_mvs.GNU file that supports builds on MVS! Thanks to Chuck Gehr for this. * tests/TSS_Test.cpp (worker): To get TSS_Test.cpp to compile on MVS we changed line 69 from: ACE_thread_key_t key = 0; to: ACE_thread_key_t key = ACE_OS::NULL_key; and line 122 from: key = 0; to: key = ACE_OS::NULL_key; Thanks to Chuck Gehr for reporting this. * ace/Reactor.cpp (dispatch): Fixed the dispatching logic so that we bail out as soon as we discover that our state has changed. Thus, we'll recompute the fd_sets used for select(). Tue Feb 18 19:02:53 1997 * ace/ReactorEx: (a) Made wakeup_all_threads() public. Thanks to Hamutal Yanay for suggesting this. (b) Change closed_for_business_ to open_for_business_. Also made sure that open and close can potentially be called multiple times from multiple threads. (c) Changed unbind and unbind_all such that they iterate through all the handles. (d) Added a check to see if the handle has been scheduled for deletion before dispatching it. Tue Feb 18 21:24:57 1997 David L. Levine * ace/IOStream.h,README: replaced ACE_WIN32 conditional with ACE_LACKS_IOSTREAM_FX. * ace/config-{mvs,win*}.h: added #define ACE_LACKS_IOSTREAM_FX. Thanks to Chuck Gehr for pointing out the need for this support for MVS. * examples/Reactor/Misc/test_demuxing.cpp: removed unused variable "done". * examples/Reactor/Misc/test_signals_1.cpp (main), examples/Reactor/Ntalker/ntalker.cpp (main): added ACE_UNUSED_ARG (sig);. Tue Feb 18 17:15:24 1997 Tim H. Harrison * ace/ace.mdp, ace/mak: Modified release configuration to build acer.dll. Tue Feb 18 11:43:04 1997 David L. Levine * ace/Log_Msg.cpp: removed destructor because it's not declared and it's empty. * ace/OS.i (thr_setprio): added another case (that is NOTSUP) for platforms with Pthreads and with LACK_SETSCHED. Thanks to Chuck Gehr for pointing this out. * tests/Reactor_Notify_Test.cpp (main): added shutdown flag so that normal termination reaches ACE_END_TEST. * tests/Reactors_Test.cpp (worker): changed "timeout" message to "Reactor shutdown" because that indicates normal termination, and won't fool the one-button test. * examples/Mem_Map/IO-tests/test_io.cpp (main): added ACE_UNUSED_ARG (sa);. * examples/Misc/test_trace.cpp (main): added ACE_UNUSED_ARG for sig1 and sig2. Tue Feb 18 03:50:10 1997 Irfan Pyarali * ace/ReactorEx: (a) Added a closed_for_business_ flag so that handle_events() cannot be called after the ReactorEx has been closed down. (b) Transfer of ownership of the ReactorEx to a new owner has changed. The transfer will not complete until all threads are ready for it (just like the handle set). ReactorEx->update_state() now looks out for changes in ownership. * examples/Reactor/ReactorEx/test_MT.cpp: (a) The test now terminates and number of iterations can be specified on the command line. (b) Graceful shutdown of ReactorEx is now exercised in the test. This is a change for the earlier infinite loop. This also shows how to gracefully close ReactorEx which is being shared by multiple threads. (c) Timers were added to the test. * ace/config{win32}: Added flag ACE_LACKS_LINEBUFFERED_STREAMBUF. Mon Feb 17 22:37:35 1997 Tim H. Harrison * ace/Log_Msg.h (ACE_RETURN): Modified all ACE_RETURN macros to use ACE_OS::last_error instead of errno. This makes these more portable to Win32. * ace/Log_Msg.cpp (log): Modified Win32 version to use FormatMessage if errnum is greater than sys_nerr. * ace/OS.i (last_error): Modified Win32 version to return GetLastError if errno == 0. Mon Feb 17 18:32:29 1997 Douglas C. Schmidt * ace/OS.h: Protected the #ifdef for CLOCK_REALTIME so that it won't conflict with an existing macro in AIX. Thanks to Chris Lahey for this. * ace/Local_Name_Space_T.h: Added Local_Name_Space.h to Local_Name_Space_T.h so that templates will work correctly on AIX. Thanks to Chris Lahey for this. * tests: Added a new test, Reactor_Notify_Test.cpp, which tests out the new max_notify_iterations() method on the Reactor. * ace/Reactor: Finished rewriting and testing the new dispatching logic of the Reactor. The new implementation guards against pathological cases where ACE_Event_Handler::handle_*() methods remove registered ACE_Event_Handler objects whose handles are pending in the dispatch_set. Previously there was no good way to guard against this. Now, it should be handled automatically. * ace: Added many minor fixes to remove warnings with the SGI C++ compiler. Thanks to Gonzalo Diethelm for suggesting this. * include/makeinclude/platform_irix6.2_sgic++.GNU: Turned on all the warnings for the SGI C++ compiler. Thanks to Gonzalo Diethelm for suggesting this. Mon Feb 17 20:59:47 1997 David L. Levine * ace/IOStream.h: added null ipfx (), etc., methods for ACE_WIN32 because its iostream class doesn't have them. * ace/OS.h: added #include of on VxWorks. * ace/Pipe.cpp (open): enabled TCP_NODELAY on VxWorks now that OS.h #includes . * ace/ReactorEx.h: made ACE_ReactorEx_Handler_Repository destructor virtual because the class has other virtual functions. * tests/IOStream_Test.cpp: removed ACE_WIN32 #ifndef, and removed q_char bool conversion operator because it shouldn't be needed. * examples/Reactor/Misc/pingpong.cpp (handle_input): cast buf_len to ssize_t to avoid signed/unsigned comparison. * examples/Service_Configurator/IPC-tests/client/\ remote_dgram_client_test.cpp (main): cast mmap.size () to ssize_t to avoid signed/unsigned comparison. Mon Feb 17 09:25:08 1997 Chris Cleeland * ace/config-linux-lxpthreads.h: Bumped the Linux kernel version number assigned to the symbol LINUX. Also added conditional defines for PTHREAD_{MAX,MIN}_PRIORITY when using Xavier Leroy's LinuxThreads. * ace/Thread_Priority.cpp: Added convert_to_os_priority() for Linux. Mon Feb 17 03:15:48 1997 Irfan Pyarali * tests/SOCK_Test.cpp (server): Changed recv_n() to recv(). * tests/tests.{mak,mdp}: Added two new tests: IOStream and Reactor_Notify. * ace/Reactor: Removed all special checks for setting ACE_Reactor::max_notify_iterations_ on WIN32 to be 1. This was made possible after we figured out that the errno was being reset after the recv() call in handle_input(). This allows ACE_Reactor_Notify::handle_input() to serve upto ACE_Reactor::max_notify_iterations_ notifications in one shot rather than just 1 on WIN32. This should speed up the Reactor on WIN32 platforms. Sun Feb 16 12:23:23 1997 Douglas C. Schmidt * ace/Reactor.cpp: Totally rewrote the ACE_Reactor's dispatching mechanism so that it now keeps track of whether the state of the wait_set_ has changed during a dispatch (i.e., whenever register_handler_i() or remove_handler_i() is called). If the wait_set_ state *has* changed, then we bail out and rerun select() in order to get the latest changes. * ace/Reactor.cpp: Changed the implementation of the ACE_Reactor_Notify class so that (1) it short-circuits a trip through the ACE_Reactor::notify_handle() method (after all, it's just going to call its own handle_input() method back) and (2) the ACE_Reactor_Notify::handle_input() method now returns a count of the number of handlers that it dispatched. * ace/Log_Msg.h: Added a (%P|%t) so that we now print out the process id and thread number for failed ACE_ASSERT() calls. * tests: Removed the unnecessary template specializations of ACE_Atomic_Op since this is already done in libACE. * ace/Reactor.cpp: Removed the #ifdef preventing the enabling of non-blocking mode for the recv() side of the Reactor's notification pipe (socket) for Win32. I believe that with the new max_notify_iterations scheme we should be all set. * ace/ReactorEx.cpp: Added an identical API for bounding the max_notify_iterations() for ReactorEx. * ace/Reactor.cpp: Enhanced the Reactor's notify() mechanism so that it is now possible to set the max_notify_iterations(), which limits the number of times that the ACE_Reactor_Notify::handle_input() method will iterate and dispatch the ACE_Event_Handlers that are passed in via the notify pipe before breaking out of its recv() loop. This is necessary to keep from starving out other Event_Handlers. Thanks to Rod Skinner for pointing out the need for this. * ace/Reactor.cpp: Fixed a bug in the WIN32 ACE_Reactor_Notify::handle_input() logic. We were calling requeue_position(0) when we should have been calling renew(). Sat Feb 15 11:46:39 1997 Douglas C. Schmidt * ace/ACE.cpp: It appears that VxWorks doesn't support fcntl(). However, it does seem to support ioctl(). Therefore, that's how we'll set the descriptors into non-blocking mode. Thanks to Dave Mayerhoefer for reporting this. * ace/SOCK_Stream.h: Corrected the documentation for ACE_SOCK_Stream::recv_n (void *buf, size_t len, int flags, const ACE_Time_Value *timeout). Thanks to Paul Roman for reporting this. * ace/SOCK_Stream.i (recv_n): Fixed a minor bug in the SOCK_Stream.i line 38: ACE_TRACE ("ACE_SOCK_Stream::send_n"); should be ACE_TRACE ("ACE_SOCK_Stream::recv_n"); Thanks to Paul Roman for reporting this. Fri Feb 14 00:40:14 1997 Douglas C. Schmidt * ace/TTY_IO.cpp (control): Moved the drop out timer value from the ACE struct to the WinNT struct. Thanks to Brad Flood for this fix. Thu Feb 13 21:24:17 1997 * ace/OS.i (event_wait): Fixed the missing check for success. * ace/Synch: Fixed problems with multiple removal of resources. Thanks to Bert (Bcraytor@aol.com) for pointing this out. * examples/Threads/test.{mdp,mak}: Reorganized project so that it is easier to use. * examples/Threads: Small changes to make tests run faster. Thu Feb 13 01:49:38 1997 Irfan Pyarali * ace/OS.i (stat): Added stat() to ACE_OS. * apps/jaws: The ACE web server has now been ported to Win32. * ace/ReactorEx: Add a new version of remove_handler(). * examples/Reactor/ReactorEx/test_MT.cpp: Fixed stuff so that only are activated. Wed Feb 12 22:58:15 1997 Douglas C. Schmidt * ace/ReactorEx: Made minor changes to the ReactorEx. * examples/Reactor/ReactorEx/test_MT.cpp: Updated Irfan's new ReactorEx test to use ACE_Tasks. Wed Feb 12 00:08:42 1997 Irfan Pyarali * ace/ReactorEx: Finished a complete rewrite of ReactorEx. The new version allows multiple threads of control to wait simultaneously in ::WaitForMultipleObjects(). This was difficult because the set of ACE_HANDLEs used in ReactorEx->handle_events() is shared between all threads. We devised a clever protocol that ensures all changes to the handle set are serialized. This serialization was achieved by using multiple (auto and manual) events and mutexes and by taking advantage of the "waitAll" semantics of WaitForMultipleObjects(). Concept of "owner" thread is introduced in ReactorEx. We need to keep track of the "owner" because we don't want multiple threads to try to expire timers. Therefore the "owner" thread is the only one allowed to expire timers. Also, the owner thread is the only thread which waits on the internal notify handle (which is used to dispatch explicit calls to ACE_ReactorEx::notify(). Initially, the creator thread of ReactorEx becomes the "owner" thread. Ownership can later be transferred among threads, just as with the standard ACE_Reactor. We also updated the Handler Repository since it now keeps track of tuples to be added and deleted from the current handle set at the appropriate time (i.e., when all threads are out of WaitForMultipleObjects() and have completed all necessary dispatching). The Handler_Repository implements the update protocol that is used to serialize changes to its internal state. Two slots were added to the parameter in the constructor and open methods of ReactorEx that will store handles used for internal management. Therefore, users can add upto MAXIMUM_WAIT_OBJECTS - 2 handles into ReactorEx. On current WinNT platforms (e.g., 3.51 and 4.0) MAXIMUM_WAIT_OBJECTS is 64. Note that the interface to ReactorEx did not change in this process. Your existing code should work without changes. Moreover, we've optimized the implementation so that if only 1 thread calls ACE_ReactorEx::handle_events() the code is very efficient. Moreover, you can dynamically add or remove threads without having to register them with the ReactorEx. * examples/Reactor/ReactorEx/test_MT.cpp: This application tests multiple threads simultaneously calling ReactorEx->handle_events(). It also shows how different threads can update the state of ReactorEx. Wed Feb 12 00:08:42 1997 Douglas C. Schmidt * ace/Synch: Added a remove() call to ~ACE_Thread_Mutex so that it will be removed (and resources cleaned up) automatically when an ACE_Thread_Mutex object goes out of scope. Thanks to Jay Denkberg for reporting this. * ace: Added a new config file (config-irix6.2-sgic++-nothreads.h) that works for non-Pthread versions of SGI 6.2. Thanks to Fred LaBar for this. * ace/XtReactor: Fixed a bunch of minor bugs that crept into the ACE_XtReactor. Thanks to Fred LaBar for reporting this. * ace/OS.i (thr_getprio): Fixed a typo in the #ifdefs so that we return ACE_NOTSUP_RETURN(-1) if threading isn't enabled. Thanks to Fred LaBar for reporting this. Tue Feb 11 11:26:03 1997 David L. Levine * ace/OS.{h,i},config-vxworks*.h,README: added ACE_HAS_CLOCK_GETTIME, and only support ACE_OS::clock_gettime if that's defined. It can be supported on Solaris 2.5, but -lposix4 is then required. * ace/Thread_Priority.*: added increment () and decrement () operations. * include/makeinclude/platform_sunos5_sunc++_4.1.GNU: added -pta back to avoid link problems with template classes that have virtual functions that are all inline, if inlining is disabled. Though we don't see the problem, other 4.1 users do. Thanks to mscallinan@CCGATE.HAC.COM for reporting this. * examples/Logger/simple-server/Logging_Handler.cpp (handle_input): cast "len" to ssize_t to prevent mixed signed/unsigned comparison. * examples/Logger/simple-server/server_loggerd.cpp (main): added ACE_UNUSED_ARG (sa);. * examples/Reactor/Misc/notification.cpp (Thread_Handler ctor): changed type of n_threads argument from int to size_t to avoid signed/unsigned comparison. Mon Feb 10 15:27:02 1997 Douglas C. Schmidt * ace/Timer_Queue: Added a virtual destructor so that subclasses deleted via ACE_Timer_Queue *'s will call the right destructor. Thanks to Stuart Powell for reporting this. * ace/Timer_Heap.cpp: Added support for automatically growing ACE_Timer_Heaps. This allows heaps to grow automatically as new ACE_Event_Handlers are added dynamically. Thanks to Stuart Powell for this enhancement. * ace/Memory_Pool: Added support that allows flags to be passed in to the MMAP_Memory_Pool. This can be used to set the appropriate type of backing store semantics (e.g., MAP_PRIVATE and MAP_SHARED). Thanks to Fred LaBar for providing this. Sun Feb 9 11:56:37 1997 Douglas C. Schmidt * ace/Map_Manager.cpp (bind_i): A recent change to Map_Manager broke the Connector since errno was getting set to ENOENT rather than EWOULDBLOCK. Thanks to Mark Rabotnikov for finding this. Sun Feb 09 21:44:34 1997 David L. Levine * ace/ACE.{h,cpp}: added static u_long is_prime (). * ace/{OS.cpp,Thread_Priority.cpp}: added comment about thread priorities only being tested for 1003.1C version of Pthreads. Thanks to Thilo Kielmann for suggesting this. * ace/OS.{h,i}: added ACE_OS::clock_gettime (). It allows applications to get high-resolution time on POSIX systems. * ace/Future.cpp (dump): cast ref_count_ to an int because g++ doesn't figure it out (it's an ACE_Atomic_Op, which does have an int conversion operator). * ace/Timer_List.cpp (constructor): added initializer for timer_id_ to prevent unitialized memory read report from Purify. * tests/IOStream_Test.cpp,Makefile: added IOStream_Test, complements of James CE Johnson . Very cool! * tests/Future_Test.cpp: replaced call to ::sin () with one to ACE::is_prime () to remove dependency on libm. * examples/IPC_SAP/UPIPE_SAP/ex1.cpp (peer1, peer2): removed unused variables c_addr and serv_addr: they were replaced by a global. * examples/Threads/future{1,2}.cpp: replaced call to ::sin () with one to ACE::is_prime () to remove dependency on libm. * netsvcs/clients/Naming/Dump_Restore/createfile.cpp: removed #include of math.h, it wasn't needed. Sat Feb 08 15:19:50 1997 David L. Levine * ace/ReactorEx.h: commented out ACE_ReactorEx_Notify::message_queue_ declaration if not ACE_WIN32 because Sun C++ chokes on it. * examples/IPC_SAP/{FILE,SPIPE}_SAP/client.cpp: declare "len" as ssize_t to avoid signed/unsigned comparison. Fri Feb 7 01:13:05 1997 Douglas C. Schmidt * ace/OS.i (select): Simplified Chris' fixes for the weird Linux select() semantics. * ace/OS: Added a new accessor method called waiters() in ACE_cond_t that returns the number of waiters on the condition variable. Thanks to Karlheinz for suggesting this. * ace/OS: Changed all the ACE_cont_t, ACE_rwlock_t, etc. so that their fields are private, but made class ACE_OS a friend. Applications should not be mucking with these fields since they may change. * ace/OS.h: Fixed a minor typo where friend class ACE_rwlock_t should be friend class ACE_OS. Thanks to Thilo Kielmann for reporting this. * ace/Log_Msg.cpp: Added a destructor to ACE_Log_Msg and changed ACE_TSS_cleanup so that it calls delete (ACE_Log_Msg *) ptr. Thanks to Per Anderson for reporting this. * tests/Map_Manager_Test.cpp: Create a file Map_Manager_Test_Key.h and move the class Key into the include file. Include this *.h file in Map_Manager_Test.cpp. This is needed for template generation on AIX. Thanks to Chris Lahey for pointing this out. Fri Feb 7 17:29:40 1997 Chris Cleeland * ace/OS.cpp (set_sched_params): added support for POSIX threads. Thanks to Thilo Kielmann for figuring it out and for providing the code. * tests/Naming_Test.cpp (test_find): Changed final delete[] to not try to delete a static buffer. :-( * tests/SOCK_Test.cpp (server): Added assertion test for modified select timeval. Fri Feb 07 13:56:24 1997 David L. Levine * ace/{OS.cpp,Thread_Priority.cpp}: added ACE_Thread_Priority support for Digital Unix. Thanks to Thilo Kielmann for figuring the priorities and priority classes out and for providing the code. * ace/High_Res_Timer.{h,cpp},config-linux*.h,README: use struct timespec instead of timespec_t, because not all platforms have the timespec_t typedef. Thanks to Marius Kjeldahl for reporting this on Linux and Chris Lahey for reporting it on AIX. * ace/IOStream.h: use "ssize_t send (...)", etc., instead of exact function prototypes. * examples/IPC_SAP/TLI_SAP/db-server.cpp: declare struct member as const char * instead of const char [] because it's not static and the struct doesn't have constructors. * examples/Reactor/Multicast/server.cpp (Server_Events ctor): reordered initializers to match declaration order. Fri Feb 07 05:08:51 1997 * ace/Synch.cpp (dump): Fixed access error. * ace/OS.h: Fixed ACE_rwlock_t friend declaration. * ace/OS.i: Moved ACE_cond_t::waiters() such that it is now visiable to NT. Also fixed ACE_OS::cond_timed_wait by returning the correct return value on a TIMEOUT. Also fixed typo in ACE_OS::sema_wait. Thu Feb 6 20:25:13 1997 Chris Cleeland * ace/OS.i (select): Adapted ACE_OS::select methods for use on platforms (such as Linux) that allow select(2) to modify its struct timeval arg. New behavior is triggered by the define ACE_HAS_NONCONST_SELECT_TIMEVAL. Thanks to Jorn Jensen for reporting this! Thu Feb 06 09:48:43 1997 David L. Levine * ace/config-sunos-sun*.h,README: added ACE_LACKS_LINEBUFFERED_STREAMBUF and ACE_LACKS_SIGNED_CHAR. * ace/IOStream.{h,cpp}: support ACE_LACKS_LINEBUFFERED_STREAMBUF and ACE_LACKS_SIGNED_CHAR so that this builds with SunC++. * examples/IOStream/client/iostream_client.cpp: reordered args and fixed argv indexes. * examples/IOStream/server/iostream_server.cpp: use ACE_DEFAULT_SERVER_PORT for default port. * tests/Naming_Test.cpp (randomize): changed type of "size" arg to size_t to avoid compiler warnings about signed/unsigned comparison. Thu Feb 06 09:40:47 1997 Chris Cleeland * ace/config-linux*.h: added typedef of timespec_t. Wed Feb 5 01:45:03 1997 Douglas C. Schmidt * ace/OS.i: Changed the Win32 implementation of all methods that call WaitForMultipleObjects() so that errno is set to WAIT_ABANDONED if the mutex is abandoned. This makes it possible for users to understand why ACE_OS methods that use synchronization operations fail. Thanks to Ivan Murphy for reporting this problem. * ace/IOStream.cpp (ACE_Streambuf): Moved the const initialization from the header file to the constructor since this is the only portable way to do this. Thanks to Michael Maxie for reporting this. * ace/OS.i: Updated the call to thr_setprio() for pthreads so that it first determines the existing scheduling parameters and then updates the priority. Thanks to Thilo Kielmann for help with this. * ace/config-osf1-4.0*.h: Updated ACE_NEEDS_HUGE_THREAD_STACKSIZE to be 1 mega to minimize porting surprises. Thanks to Thilo Kielmann for help with this. * tests/Naming_Test.cpp: Cleaned up a few minor things related to int i = 0 vs. size_t i = 0. * ace/SOCK_Dgram.cpp: Added a new macro called ACE_HAS_SOCKADDR_MSG_NAME, which is used on platforms (e.g., DG/UX) that require a cast to (struct sockaddr *) for the msg_name field of struct msghdr. Wed Feb 05 10:45:41 1997 David L. Levine * ace/IOStream.h: replaced __*manip with expanded types, because Sun C++ doesn't have those typedefs; and added complete prototypes for send, recv, send_n, and recv_n. * ace/IOStream.cpp: fixed "#define ACE_IOSTREAM_C" to keep g++ sane. * ace/Hash_Map_Manager.{h,cpp},Map_Manager.{h,cpp}: replaced DEFAULT_SIZE with ACE_DEFAULT_MAP_SIZE so that Naming_Test runs on SunC++ 4.1. * ace/High_Res_Timer.*: added optional scale factor. * examples/IOStream/{client,server}/Makefile: addd -g++ if building with gcc. * tests/Naming_Test.cpp: moved declaration of "i" out of for loop because it is used after the loop. * examples/ASX/UPIPE_Event_server/{Consumer,Supplier}_Router.cpp (open): return 1 if init () succeeds. There's a commented-out call to activate the objects that would (should?) return a value. * examples/IPC_SAP/FIFO_SAP/FIFO-client.cpp (main): declare n as ssize_t instead of size_t to avoid compiler warning about signed/unsigned comparison. Tue Feb 4 19:06:52 1997 Douglas C. Schmidt * ace/Signal.cpp: Fixed all the ACE_Sig_Handler[s] methods so that they now use ACE_Guard, rather than ACE_TSS_Guard, *unless* they are actually performing callbacks to user-code. Not only is this faster, but it also avoids thread-specific storage key leaks on platforms like Solaris! * ace/OS.cpp (thr_keyfree): Added a new #ifdef for ACE_HAS_THR_KEYDELETE, which is defined for UNIXWARE. This fixes a nasty problem with leaking thread-specific keys. Thanks to Nigel Owen for reporting this. * ace/Message_Block.cpp: Added a #include for "ace/Service_Config.h". * ace/Malloc.i: Fixed a few warnings by removing the names of unused parameters. * ace: Added many minor changes to ACE so that it will work on DG/UX. Thanks to Michael Maxie for all these. * ace/LSOCK_Stream.cpp: Applied the same fix as to LSOCK.cpp. * ace/LSOCK.cpp: Removed the cast of 0 to (char *) for msg_name since some platforms use (struct sockaddr *). By omitting the cast the compiler will figure it out correctly. Thanks to Michael Maxie for this. * ace/IOStream: Added a new template adapter for creating an iostream-like object using an ACE IPC Stream for the actual I/O. Thanks to James CE Johnson for this. * examples/Misc/test_iostreams.cpp: Added a test that illustrates how the new ACE_iostreams mechanism works. Thanks to James CE Johnson for this. * ace/Message_Block: Updated the ACE_Message_Block implementation to use ACE_Service_Config::alloc() if the user doesn't supply a customize version. This also means that we never delete the allocator_strategy_, so we can remove this flag and reduce the amount of storage by 4 bytes. Thanks to Irfan for noticing that we can do this. * ace/platform_dgux4_epc.h: Added a new platform config file for DG/UX. Thanks to Michael Maxie for this. * ace/config-dgux-4.11-epc.h: Added a new config file for DG/UX. Thanks to Michael Maxie for this. Tue Feb 04 18:26:01 1997 * ace/Service_Config.cpp (alloc): The implementation now creates a ACE_New_Allocator rather than a ACE_Allocator_Adaptor. If you still want the old behavior, simply provide your own custom allocator singleton for ACE_Service_Config. * ace/OS.i (mktemp): Added the missing ACE_INLINE directive. * ace/OS.h: ACE_HAS_INLINED_OSCALLS is now automatically defined when __ACE_INLINE__ is defined. This avoids mysterious linking problems that occur otherwise. * ace/Malloc: Added a virtual destructor to ACE_Allocator. Also added a new class ACE_New_Allocator which is a sub-class of ACE_Allocator. This class uses the new/delete operators to allocate and free up memory. Please note that the only methods that are supported are malloc() and free(). All other methods are no-ops. If you require more functionality, please use: ACE_Allocator_Adapter > This will allow you to use the added functionality of bind/find/etc. while using the new/delete operators. Mon Feb 3 15:35:24 1997 Douglas C. Schmidt * ace/config-aix-*.h: Added a (char *) cast to ACE_DEFAULT_BASE_ADDR. Thanks to John Cosby for reporting this. * ace/OS.cpp: Added a new set() method that sets the Time_Value from a double. Thanks to Brad Flood for this suggestion. * ace/OS: Changed ACE_OS::flock_t to ACE_OS::ace_flock_t to avoid a name clash on DG/UX. Thanks to Michael Maxie for reporting this. Tue Feb 4 03:02:52 1997 Irfan Pyarali * tests/Naming_Test.cpp: Added timing and made debug print outs optional. Also added randomization of the test data. * ace/OS.h: Fixed prototype for gethrtime () Mon Feb 03 21:00:56 1997 David L. Levine * ace/OS.h: define ACE_SCOPE_PROCESS and ACE_SCOPE_THREAD even if ACE_HAS_THREADS is not defined. Thanks to Michael Maxie for pointing this out. * examples/Threads/{process_mutex.cpp,process_semaphore.cpp, task_three.cpp,thread_manager.cpp,thread_specific.cpp} (main): added ACE_UNUSED_ARG (sa);. * examples/Threads/reader_writer.cpp: fixed declaration of "shared_data" to be "static volatile" instead of "volatile static", and removed unused variable "n". * examples/Threads/thread_pool.cpp: removed unused variable "result". Sun Feb 02 21:24:02 1997 David L. Levine * ace/OS.h: changed hrtime_t to ACE_hrtime_t. * ace/{config-win*.h,README}: added #define ACE_HAS_PENTIUM to enable gethrtime () support. * ace/High_Res_Time.{h,i,cpp}: removed platform-specific #ifdef's, instead added "unsupported ()" static member function; changed changed signature of elapsed_time to take time reference as argument instead of return value; added elapsed_time (ACE_Time_Value &) and elapsed_time_incr (ACE_Time_Value &). * examples/Thread/context_switch.cpp: use ACE_High_Res_Timer instead of the old Timer adapter. * ace/config-aix-4.1.x.h: fixed typo: #defind ACE_HAS_LONGLONG_T. * ace/config-aix-4.2.x.h: added #define ACE_HAS_LONGLONG_T. * ace/Thread_Priority.{h,cpp}: moved #include of OS.h from .cpp to .h file. Sun Feb 02 10:30:29 1997 David L. Levine * ace/Local_Name_Space.cpp: removed ACE_Map_Manager, ACE_Map_Iterator, and ACE_Map_Entry: they don't appear to be used and, without including their headers, this file won't compile. * ace/Hash_Map_Manager.cpp (Hash_Map_Manager (ACE_Allocator *)): reordered initializers to match declaration order. Sat Feb 1 15:11:28 1997 Douglas C. Schmidt * include/makeinclude/platform_aix4.2.GNU (LD): Removed the -qnoro flag since it is no longer needed. Thanks to Rob Jordan for reporting this. Sat Feb 1 03:25:21 1997 Irfan Pyarali * ace/SString.cpp: Added two methods to the wide string implementation for high-performance. Even though these methods are somewhat ugly and not the "OO" way of doing things, performance was at stake here. * ace/Registry_Name_Space.cpp (resolve): Fixed the implementation by correctly figuring out the size of the value in the Registry. This allows us to dynamically allocated the correct amount of memory. * ace/Registry: Fixed the constant MAX_CONTEXT_NAME_SIZE to be the maximum path length. * ace/Naming_Context.cpp: Fixed various memory leaks. * ace/Local_Name_Space_T.h: Replaced the simple-minded Map_Manager with the new (improved) Hash_Map_Manager. * ace/Local_Name_Space.cpp: Added new methods operator!= and hash required by the map. * ace/Hash_Map_Manager.cpp (ACE_Hash_Map_Manager): Added an extra constructor. * tests/Naming_Test.cpp: Removed memory leaks. Fri Jan 31 19:39:48 1997 David L. Levine * ace/Hash_Map_Manager.cpp (ctor): reordered initializers to match declaration order. * tests/Time_Value_Test.cpp: cast double argument to long because there no longer is a constructor that takes a double. * ace/Hash_Map_Manager.{h,cpp}: removed #include of ace/Hash_Map_Manager.i because it doesn't exist. Protected .cpp file against multiple includes. Moved #include of "ace/Malloc.h" from .h to .cpp file. * ace/Map_Manager.cpp (current_size, total_size): cast -1 to size_t to avoid warning about signed-to-unsigned conversion. * ace/OS.h: moved hrtime_t typedef for ACE_WIN32 so it doesn't get defined twice. * ace/OS.i (getservbyname): one last ACE_HAS_NONCONST_GETBY change: missed "lproto" to "proto". * bin/create_ace_build: added checks for existing symlinks, so now the script can be re-run safely at any time on a build tree to update it. Fri Jan 31 02:16:30 1997 Douglas C. Schmidt * ace/config-aix-*.h: Made the default value for ACE_DEFAULT_BASE_ADDR 0x80000000 to work around restrictions with AIX. Thanks to Rob Jordan for this. * examples/Map_Manager: Added a new example of the Hash_Map_Manager. * tests/Map_Manager: Integrated the Hash_Map_Manager into the Map_Manager test and greatly improved the test (e.g., by adding timing). * ace: Added a new implementation of the Map_Manager called Hash_Map_Manager. This, of course, uses hashing rather than linear search. The result should be a much faster implementation for many types of applications. Thu Jan 30 13:55:08 1997 Douglas C. Schmidt * ace/Map_Manager: Changed the return type of total_size() and current_size() to size_t. * ace/OS: Had to remove the ACE_Time_Value (double) constructor since it caused ambiguities with ACE_Time_Value (long). Thanks to Per Andersson for figuring this out. * include/makeinclude/platform_linux_lxpthread.GNU (CXX): Added -D_REENTRANT to make things work correctly in MT programs. Thanks to Marius for this fix. * ace/OS.h: Added several extra constructors for ACE_Time_Value so that it won't cause problems with the new ACE_Time_Value (double) constructor. * ace/Log_Record.cpp (ACE_Log_Record): Added an "L" to the 0 initial value used for time_stamp_. Thanks to Marius for reporting this. * ace: Added the new config-aix-4.2.x.h file, which supports the AIX4.2 platform. Thanks to Rob Jordan for this. * include/makeinclude/platform_aix4.2.GNU: Added support for the new AIX4.2 platform. Thanks to Rob Jordan for this. * ace/OS.h: It's now possible to override ACE_DEFAULT_BASE_ADDR in a config.h file. This is important for platforms that need to put shared memory segments at particular address ranges. Thanks to Rob Jordan for suggesting this. Thu Jan 30 16:01:37 1997 David L. Levine * ace/{config-aix-4.1.x.h,README}: added ACE_HAS_AIX_HIRES_TIMER, see change to gettimeofday in OS.i below; and ACE_HAS_LONGLONG_T. * ace/OS.i (gettimeofday, gethrtime): use read_real_time () if ACE_HAS_AIX_HIRES_TIMER. Thanks to Bob Olson for this suggestion. * ace/OS.h: define hrtime_t as long long if ACE_HAS_AIX_HIRES_TIMER. * ace/OS.{i,cpp}: uninlined ACE_OS::gethostbyname (), and ACE_OS::inet_ntoa () on VxWorks, because they have static char arrays. * ace/OS.i (gethostbyaddr, getservbyname, gethostbyaddr, gethostbyname, getservbyname_r): with ACE_HAS_NONCONST_GETBY, instead of copying the const argument, just cast it to (char *). Thanks to Michael Maxie for pointing out the problem with the nonstatic char arrays with sizes determined at runtime. * ace/High_Res_Timer.*: added ACE_HAS_AIX_HIRES_TIMER support. Also, renamed get_time () to elapsed_microseconds (). * examples/Threads/{Timer.h,context_switch_time.cpp}: ACE_High_Res_Timer::elapsed_microseconds () instead of ACE_High_Res_Timer::get_time (). * bin/create_ace_build: added this script: it creates an ACE build tree in directory "build/" below the current directory, which must be a ACE "top level" directory (such as $WRAPPER_ROOT). The build tree directory structure mirrors that of the ACE top level directory structure, except that instead of containing any plain files, it contains only symlinks to the files in the ACE top level structure. Thu Jan 30 06:57:50 1997 David L. Levine * ace/Thread_Priority.cpp (convert_to_os_priority): changed switch (priority_class) to switch (priority_class_). Thanks to Chris Lahey for pointing this out. Also, return -1 on other than Solaris, Win32, and VxWorks. Wed Jan 29 22:05:01 1997 Douglas C. Schmidt * tests/Naming_Test.cpp: Added the prefix "test_" to the bind(), find(), rebind(), and unbind() functions. This avoids name clashes with the bind() call from the socket API. Thanks to Marius for this info. * ace/OS.cpp (ACE_Time_Value): Added a new constructor that makes it possible to construct an ACE_Time_Value from a double. Thanks to Brad Flood for this. * ace/OS.i (thr_join): If ACE_HAS_THREADS is defined, but none of the threading APIs match (e.g., AIX) then we'll return ACE_NOTSUP_RETURN(-1). Thanks to Chris Lahey for help with this. * include/makeinclude/platform_aix.GNU: Made some changes to the type of dynamic linker and libraries used by AIX 4.1. Thanks to Chris Lahey for help with this. * ace/config-aix-4.1.x.h: Changed from BSD 4.3 to 4.4. Thanks to Chris Lahey for help with this. Wed Jan 29 09:03:48 1997 David L. Levine * ace/OS.h: moved ACE_id_t and ACE_pri_t typedefs out of the ACE_HAS_THREADS section. * ace/OS.cpp: fixed ACE_OS::set_sched_params on Win32 and VxWorks. * ace/Scheduling_Parameters.*, ace/Thread_Priority.*: updated comments. * examples/Threads/{context_switch_time.cpp,Timer.h,Makefile}: added context switch timing test. Currently only works on Suns because that's the only platform for which ACE has a high-resolution timer. * Makefile: added chmod of VERSION file in TIMESTAMP macro. Wed Jan 29 00:59:12 1997 Douglas C. Schmidt * include/makeinclude/platform_linux_lxpthread.GNU (CXX): Removed the -D_MIT_POSIX_PTHREADS symbol since we're using Xavier's threads instead. Thanks to Marius Kjeldahl for reporting this. * ace/config-linux-lxpthreads.h: Removed the _MIT_POSIX_PTHREADS symbol since we're using Xavier's threads instead. Thanks to Marius Kjeldahl for reporting this. Tue Jan 28 23:32:58 1997 Douglas C. Schmidt * ace/SString: Added hash() methods to each ACE String class so that we can use this with the new ACE_Hash_Set implementation of ACE_Map_Manager. * ace/ACE.h (ACE): Added a UNICODE version of hash_pjw() so that we can use it to hash ACE_WString. * ace/OS.i (thr_setprio): Fixed a typo that was left over from a previous change. Thanks to Fred LaBar for reporting this. * apps/Gateway/Gateway/{proxy_config,consumer_config}: Added comments to these config files so they are easier to understand. Thanks to Chuck Gehr for motivating this. * apps/Gateway/Peer/Peer.cpp: Changed the name from connection_id_ to proxy_id_, which is more accurate. * apps/Gateway/Peer/Peer.cpp: Added a destructor to Peer_Handler so that it can clean itself up properly when shutdown with a signal. This fixes a nasty bug. * ace/config-win32-msvc4.x.h (ACE_HAS_MFC): By default, ACE now enables ACE_HAS_MFC. This makes it possible to use AfxBeginThread() with the ACE_THR_AFX flag. * ace/OS.cpp: Fixed a typo in the call to ::AfxBeginThread() function. Thanks to Karlheinz for reporting this. * apps/Gateway/Peer/Peer.cpp: Removed all uses of the Map_Manager from the Peer. There's only ever one connection from a Gateway per-Peer, so what was this doing here anyway?! It was causing problems due to multiple deletions, so removing it improves robustness of the tests. * ace/OS.i: Commented out the "extern char **_sys_siglist" definition since this was conflicting with the definition in Solaris. If some platforms needs this, we'll need to add a specific #ifdef. Tue Jan 28 21:57:45 1997 David L. Levine * ace/OS.{h,cpp}: added ACE_OS::set_sched_params (). It permits platform-independent setting of thread priorities and priority classes. It is currently supported on Solaris, Win32, and VxWorks. * ace/Scheduling_Parameters.{h,i,cpp}, ace/Thread_Priority.{h,i,cpp}, ace/Makefile: Added these two classes to support ACE_OS::set_sched_params (). Tue Jan 28 12:42:39 1997 Irfan Pyarali * ace/ace.mdp: Added the "Using MFC in a Shared DLL" flags. * tests/test_config.h (ACE_INIT_LOG): Made this UNICODE safe. * tests/Pipe_Test.cpp (main): Added an iteration count to control the number of children created by the main process. * ace/Memory_Pool.cpp (init_acquire): cast this->minimum_bytes_ to size_t to avoid compiler warning if size_t is unsigned. * ace/OS.h: Added strncat to the OS class. Tue Jan 28 09:13:00 1997 David L. Levine * ace/ACE.cpp (ACE::ldfind), ace/Local_Name_Space_T.cpp, ace/Local_Token.cpp (ACE_TPQ_Entry::ACE_TPQ_Entry), ace/Log_Msg.cpp (ACE_Log_Msg::msg, ACE_Log_Msg::find), Memory_Pool.cpp (ACE_MMAP_Memory_Pool::ACE_MMAP_Memory_Pool), ace/Naming_Context.cpp (ACE_Naming_Context::open), ace/Parse_Node.cpp (ACE_Location_Node::open_handle), ace/Registry.cpp (ACE_Predefined_Naming_Contexts::is_local_host, ACE_Registry::Binding_Iterator::Object_Iteration::next_n, ACE_Registry::Binding_Iterator::Context_Iteration::next_n), tests/UPIPE_SAP_Test.cpp: changed "sizeof char" to "sizeof (char)" because g++ and Sun C++ (properly) choked on it. * ace/Local_Name_Space_T.cpp (create_manager_i): -- ::strncat () instead of ACE_OS::strcat () -- "lock_name_for_backing_store" instead of "lock_name_for_local_name_space" * ace/Naming_Context.cpp (both constructors): reordered initializers to match declaration order. * include/makeinclude/platform_sunos5_g++.GNU: removed -fno-strict-prototypes because it's not needed with SunOS 5.5.1. Mon Jan 27 21:33:00 1997 Irfan Pyarali * tests/Naming_Test.cpp (main): Made modifications to the test to make it more dynamic. Also made it work with UNICODE and ACE_Naming_Context. * ace/Local_Name_Space_T.cpp (create_manager_i): Added a better naming scheme for the locks. * ace: Changed the calculations of string lengths such that the size of the character type is carefully considered. The following were affected: ACE.cpp (ACE::ldfind) Local_Token.cpp (ACE_TPQ_Entry::ACE_TPQ_Entry) Log_Msg.cpp (ACE_Log_Msg::msg, ACE_Log_Msg::find) Memory_Pool.cpp (ACE_MMAP_Memory_Pool::ACE_MMAP_Memory_Pool) Naming_Context.cpp (ACE_Naming_Context::open) Parse_Node.cpp (ACE_Location_Node::open_handle) Registry.cpp (ACE_Predefined_Naming_Contexts::is_local_host, ACE_Registry::Binding_Iterator::Object_Iteration::next_n, ACE_Registry::Binding_Iterator::Context_Iteration::next_n) * ace/OS.h: Added UNICODE support for ACE_DEFAULT_LOCALNAME. * ace/Proactor.cpp: Redid "lost" changes to add UNICODE support to: /* Proactor */ ACE_Overlapped_File::ACE_Overlapped_File ACE_Overlapped_File::open * ace/Registry_Name_Space.h: Changed the order of #include and #define as that the correct set of MACROS are defined for the include files. * tests/MM_Shared_Memory_Test.cpp: Added UNICODE support. Mon Jan 27 09:16:03 1997 David L. Levine * include/makeinclude/platform_sunos5_sunc++.GNU, include/makeinclude/platform_sunos5_sunc++_orbix.GNU, ace/config-sunos5.5-sunc++-4.x-orbix.h ace/config-sunos5.5-sunc++-4.x.h: disabled exception handling by commenting out ACE_HAS_EXCEPTIONS in the config files and adding -noex to the platform files, because it causes trouble, at least on MP machines. Mon Jan 27 14:54:31 1997 Douglas C. Schmidt * ace/Memory_Pool.h: Added code to ACE_MMAP_Memory_Pool_Options to take a minimum_bytes parameter. This is needed to prevent mmap remapping when a large segment is requested. Thanks to Fred LaBar for this. Sun Jan 26 13:39:13 1997 Douglas C. Schmidt * ace/OS.i: Changed the typo sis_siglist to sys_siglist. Also, changed the logic from #if !defined (ACE_HAS_SYS_SIGLIST) to #if defined (ACE_HAS_SYS_SIGLIST) since this makes more sense... Thanks to Nanbor Wang for noticing this. Sat Jan 25 20:30:23 1997 David L. Levine * ace/config-sunos5.5-sunc++-4.1.h: commented out ACE_HAS_EXCEPTIONS #define because -noex is required with it, and that causes core dump during thread exit on multiprocessor UltraSparcs. * include/makeinclude/platform_sunos5_sunc++_4.1.GNU: added -noex back because of core dump during thread exit on multiprocessor UltraSparcs. * examples/ASX/Event_Server/Event_Server/Event_Analyzer.cpp, examples/ASX/UPIPE_Event_Server/Event_Analyzer.cpp (control): added "default" case to switch statement to eliminate compiler warnings about enumeration values not being handled in switch. * examples/ASX/UPIPE_Event_Server/event_server.cpp (consumer): removed unused variable "iter". Sat Jan 25 12:50:24 1997 Douglas C. Schmidt * ace/OS.i: Updated all the cond_timedwait() and cond_wait() methods so that they decrement the count of waiters by one even when errors occur. Thanks to Irfan for finding this. * ace/Map_Manager.cpp: Updated the ACE_Map_Iterator code so that it no longer crashes if the Map has been closed. Thanks to Slawomir Kuzniar for reporting this. Sat Jan 25 11:34:56 1997 Irfan Pyarali * ace/SOCK_Connector.cpp (complete): Added a sleep of zero seconds which allows non-blocking connects to work properly on NT. * ace/config-winnt-4.0-msvc4.x.h and config-win32-msvc4.x.h: Added ACE_HAS_BROKEN_NON_BLOCKING_CONNECTS. * ace/OS.i: Moved out all code for Time_Value from #if region. It is common to all. * ace/Reactor: Added helper routines to stop the VC++ compiler from bitching about destructors in exception handling code. * ace/ace.{mak,mdp}: Removed Time_Value.cpp from project. * tests/tests.{mak,mdp}: Corrected the creation of SOCK_Test and Message_Blob_Test executables and temporary files. Fri Jan 24 09:01:50 1997 David L. Levine * examples/Connection/misc/Connection_Handler.cpp: added specialization of ACE_Svc_Handler so that subproject will build with g++ without optimization. * apps/Gateway/Gateway/Proxy_Handler.cpp: added specializations of ACE_Svc_Handler and ACE_Svc_Handler so that subproject will build with g++ without optimization. * tests/Reactor_Exceptions_Test.cpp (main): added ACE_UNUSED_ARG for argc and argv when ACE_HAS_EXCEPTIONS is not defined. * performance-tests/Misc/test_mutex.cpp: made destructor of Thread_Mutex_Derived virtual because the class has other virtual functions. Thu Jan 23 11:51:45 1997 David L. Levine * ace/config-sunos5.5-g++.h: commented out ACE_HAS_EXCEPTIONS because -fhandle-exceptions is broken in g++ 2.7.2 (and is required in order to use exception handling); also, added ACE_HAS_INLINED_OSCALLS, if __ACE_INLINE__ is #defined. * ace/config-sunos5.5-sunc++-4.1.h: added ACE_HAS_INLINED_OSCALLS, if __ACE_INLINE__ is #defined. Wed Jan 22 15:04:47 1997 Douglas C. Schmidt * ace/OS.h: Moved the ACE_TIMER_SKEW macro to below the #inclusion of config.h and updated it so that it can be overridden in the config.h file if necessary. Thanks to Bob Olson for motivating this. * ace/OS.cpp: Fixed the implementation of ACE_Thread_ID::operator== so that it works correctly when thread ids and thread handles aren't ints. Thanks to Chuck Gehr for reporting this. * ace/OS.i (thr_getprio): Moved a stray #else into the right place. Thanks to Chuck Gehr for reporting this. * ace/OS.i (sema_post): this->count_++ should have been s->count_++. Thanks to Chuck Gehr for reporting this. * ace/Synch_T.cpp: Added an extern "C" definition for ACE_TSS_C_cleanup(). Thanks to Chuck Gehr for reporting this. * ace: Added a new #define called ACE_LACKS_SYS_NERR to the config files for MVS and VxWorks. This is used in OS.cpp as follows: #if defined (ACE_LACKS_SYS_NERR) int sys_nerr = ERRMAX + 1; #endif /* ACE_LACKS_SYS_NERR */ Thanks to Chuck Gehr for reporting this. * Removed all #inclusions of "ace/Time_Value.h." This file no longer contains anything besides a #include "ace/OS.h" and is only kept around due to backwards compatibility. * ace: Moved the contents of Time_Value.h into OS.h to reduce the confusion that arises from the #inclusion of "config.h" in Time_Value.h. Also merged the contents of Time_Value.{i,cpp} into OS.{i,cpp}. Thanks to the MDA guys for motivating this. * tests/Reactor_Exceptions_Test.cpp: Added a new test that exercises the Reactor with C++ exceptions. Thanks to Luca for the test. * ace/Reactor.cpp (handle_events): Added Win32 structured exception handling support to the ACE_Reactor::handle_events() method so that it correctly releases the token lock when Win32 SEH occur in callback routines. Thanks to Luca for reporting this problem. * ace: Added a new macro called ACE_HAS_EXCEPTIONS, which indicates that the compiler supports C++ exception handling. * include/makeinclude/platform_sunos5_sunc++*.GNU: Commented out the -noex flag for now. Hopefully, things will work correctly now. * ace/Thread_Manager.cpp (exit): Removed the final acquire() on ace_mon, which is no longer necessary since the Guard classes now keep track of whether they are "owned". Thanks to Karlheinz and Detlef for this fix. Wed Jan 22 09:05:31 1997 David L. Levine * Makefile,VERSION: modified top-level Makefile (and VERSION) to add a timestamp to the VERSION file if creating a release from the /project/adaptive/ACE_wrappers directory. If it causes problems, this will disable it: % make TIMESTAMP= release. * ace/Local_Tokens.cpp (dump): replaced "ACE_TSS" with "ACE_TPQ_ENTRY" so that ACE_NO_TSS_TOKENS is supported. * ace/Synch.h: fixed typo in comment header for ACE_Thread_Semaphore * ace/config-vxworks-ghs-1.8.h,config-vxworks5.2-g++.h, config-unixware-2.01-g++.h: protect ACE_HAS_INLINED_OSCALLS #defined with #if defined (__ACE_INLINE__). * apps/Gateway/Gateway/Event_Channel.cpp (open): added ACE_UNUSED_ARG (sig);. * examples/ASX/Event_Server/Event_Server/Peer_Router.h: declared a friend of class Peer_Router_Context because it has a private destructor, to eliminate compiler warning about not having any friends. * examples/ASX/Event_Server/Event_Server/Supplier_Router.cpp (open): added return 0 in "true" branch of if statement so that the function always returns a value. Tue Jan 21 09:19:44 1997 David L. Levine * tests/Reader_Writer_Test.cpp (reader): commented out unused variable "n"; also, commented out unused function print_usage_and_die. * tests/TSS_Test.cpp, Thread_Manager_Test.cpp (main): added ACE_UNUSED_ARG (sa);. * tests/Thread_Pool_Test.cpp (open): added return 0 at end. Tue Jan 21 11:00:12 1997 Douglas C. Schmidt * apps/Gateway/Gateway/Gateway.cpp (parse_args): There was a small bug in parse_args (latest beta), it mixed proxy and consumer conf files. Thanks to Per Andersson for reporting this. Mon Jan 20 13:29:28 1997 David L. Levine * ace/OS.i, ace/Task.h, and ace/Thread_Manager.h: changed a few occurrences of NULL to 0 (for other than Win32 platforms), primarily to avoid compiler warnings on VxWorks if ACE.h isn't #included before stddef.h. * netsvcs/clients/Naming/Dump_Restore/Dump_Restore.cpp (handle_input): replaced %d format with %hu for u_short arg. * netsvcs/clients/Tokens/deadlock/deadlock_detection_test.cpp (run_writer): initialized variable "t" to avoid compiler warning. * examples/Connection/misc/Connection_Handler.cpp (handle_timeout): added ACE_UNUSED_ARG (tv); also, added explicit int return type to definition of Connection_Handler::close (u_long). * examples/Threads/task_four.cpp (Invoker_Task::svc): moved declaration of "task" out of for loop because it is also used after the for loop. * netsvcs/lib/Name_Handler.cpp, Server_Logging_Handler.cpp, TS_Clerk_Handler.cpp, TS_Server_Handler.cpp, Token_Handler.cpp: added ACE_UNUSED_ARG (sig);. Sun Jan 19 11:10:49 1997 David L. Levine * include/makeinclude/platform_sunos5_sunc++.GNU, platform_sunos5_sunc++_4.1.GNU: added comment about compiler warnings with +w option. Also, added +w to platform_sunos5_sunc++_4.1.GNU. With the other changes in this ChangeLog entry, there no longer should be significant warnings from Sun C++ when building ACE. * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp (Peer_Handler::put): added ACE_UNUSED_ARG (tv);. * examples/IPC_SAP/SPIPE_SAP/NPServer.cpp (main), netsvcs/clients/Tokens/invariant/invariant.cpp (main): commented out argc and argv. * examples/Mem_Map/file-reverse/file-reverse.cpp (main): removed unused variable "cp". * netsvcs/clients/Tokens/manual/manual.cpp (handle_input, handle_exception): added ACE_UNUSED_ARG (fd); and (create_proxy): added return statement at end: even though it should never be reached, it eliminates a compiler warning. * examples/OS/Process/process.cpp, examples/Reactor/Misc/test_reactors.cpp, netsvcs/clients/Tokens/deadlock/deadlock_detection_test.cpp, netsvcs/clients/Tokens/mutex/test_mutex.cpp, netsvcs/clients/Tokens/rw_lock/rw_locks.cpp, performance-tests/TTCP/ORBeline/ttcp_i.cpp, performance-tests/TTCP/Orbix/ttcp_i.cpp (main): return 0 instead of 42. Sat Jan 18 10:54:25 1997 Prashant Jain * java/src/README: Updated the README file to indicate how documentation for Java ACE cab be automatically generated. Fri Jan 17 11:47:10 1997 Douglas C. Schmidt * ace/OS.h: Added an equivalent set of ACE_LSOCK_{STREAM,ACCEPTOR,CONNECTOR} macros to complement the ones for ACE_SOCK_*. Thanks to Gonzalo Diethelm for suggesting this. * ace/OS.cpp (ACE_Thread_Adapter): Added a new feature that allows logging features to be inherited by threads. It works with those OSs (e.g., Win32) that use ACE_Thread_Adapter class. At some point, we might do this for all the OSs. Thanks to Luca for this. * examples/Connection/misc/Connection_Handler.cpp: Added a new example that illustrates how to use the Acceptor pattern to create multiple threads, each running its own Reactor. * ace/Log_Msg.cpp (dump): Some of the variables in the dump() method have the wrong format specification type. These are: restart_ (%d), flags_ (%x), priority_mask_ (%d). They are now fixed, thanks to Luca. * tests/Priority_Task_Test.cpp (open): Add an ACE_ASSERT to make sure that the tasks activate() correctly. Thanks to David for finding this. * ace/config-linux-lxpthreads.h: Added #defines for ACE_HAS_AUTOMATIC_INIT_FINI and ACE_HAS_SVR4_DYNAMIC_LINKING. Thanks to Marius for this. * ace/Malloc.h: Changed the typedef of ACE_Malloc_Align to a macro called ACE_MALLOC_ALIGN to allow users to override this value in their config.h file. This is necessary for platforms that don't have "long" word alignments. Thanks to Fred LaBar for this suggestion. * ace/OS.h: Added an #ifdef check for ACE_HAS_IRIX62_THREADS and if so, we'll use the if (&a) /* null */; } form of the ACE_UNUSED_ARG macro to avoid unnecessary warnings. Thanks to Fred LaBar for testing this out. Fri Jan 17 16:33:25 1997 David L. Levine * ace/High_Res_Timer.*: added elapsed_time () and get_time (). * netsvcs/clients/Tokens/collection/collection.cpp, rw_locks.cpp: commented out unused variables to avoid compiler warnings; and return 0 from main (). * include/makeinclude/rules.local.GNU, netsvcs/lib/Makefile, examples/Service_Configurator/IPC-tests/server/Makefile: fixed ESOBUILD mechanism to work on all platforms, not just Linux. Thanks to Marius Kjeldahl for this fix. * ace/OS.i and OS.cpp: uninlined functions that use varargs, because they usually won't get inlined anyways. * ace/OS.cpp (thr_create): added #else clause to be sure that always sparam.sched_priority always get set to the priority argument. * netsvcs/clients/Naming/Client/Client_Test.cpp: commented out unused parameters and wrapped combined assignments/conditional values to avoid compiler (g++) warnings. * tests/Priority_Task_Test.cpp: added check for successful thread spawn, and ACE_NEW_THREAD to svc () so that messages get logged. Thu Jan 16 17:03:47 1997 Douglas C. Schmidt * include/makeinclude: Added support for shared object files on Linux. Thanks to Marius Kjeldahl for his help with this. * ace: Merged in the IRIX support, mainly the missing netdb reentrant functions. Thanks to Gonzalo Diethelm and Carlos O'Ryan for their help. * ace/Timer_{List,Heap,Queue}: Changed iterator() to iter() to avoid name clashes with STL (ugh). * ace/Timer_{Heap,List}.cpp: Added ACE_BUILD_DLL so that things will link. Thanks to John Morey for reporting this. * ace/Synch_T.h: Fixed: class ACE_Write_Guard: method: tryacquire_write so that it will call ...->lock_->tryacquire_write() and not ...->lock_->acquire_write(). Thanks to Alexandre Karev for this fix. Thu Jan 16 15:51:16 1997 David L. Levine * Dump.cpp (register_object): initialized "slot" so that g++ doesn't complain about uninitialized use. * Reactor.cpp (initialized): use ACE_GUARD_RETURN instead of ACE_GUARD because the function returns a value; (find): initialize "i" if handle is out of range so that g++ doesn't complain about uninitialized use. * Service_Repository.cpp (remove): removed unused variable "handle". * Thread_Manager.h: made destructor virtual now that spawn_i () is virtual. * Timer_Heap.cpp: changed some int loop indicies to size_t to make sure that comparisons are consistently signed or unsigned. * OS.h, config-vxworks*.h: removed ACE_HAS_GREENHILLS_SOCKETS ACE macro because the code it wrapped applies to all VxWorks compilers, not just GreenHills. Wed Jan 15 02:06:21 1997 Douglas C. Schmidt * ace/ACE.cpp (round_to_pagesize): If _SC_PAGESIZE is enabled then we set the ACE::pagesize_ variable using sysconf(2). Thanks to James Mansion for this suggestion. Wed Jan 15 02:06:21 1997 Douglas C. Schmidt * ace/Timer_Queue.cpp (expire): Changed a line of code from ACE_Timer_Queue_Iterator &iterator (this->iterator ()); to ACE_Timer_Queue_Iterator &iterator = this->iterator (); so that the Visual C++ compiler can grok it. Thanks to John Morey for reporting this. * ace/Reactor.cpp: Modified the close() method so that it can be called multiple times with no bad side-effects. * ace/Pipe.cpp: Modified the close() method so that it can be called multiple times with no bad side-effects. * ace/Reactor: Added an initialized() method that indicates whether the Reactor was successfully initialized. Also rearranged the code in ACE_Reactor::open() so that initialized_ is only set at the end of the method when everything succeeds. If things *don't* succeed, we call close() on the way out. Thanks to Luca for these suggestions. * ace/Reactor.cpp (close): When closing down the ACE_Reactor, we now set initialized_ back to 0 so that it can be reopened again later. * tests/Reader_Writer_Test.cpp: There were some problems with this test due to the fact that on many pthreads platforms pthread_t isn't an int (it's a struct). Thanks to Chuck Gehr for the fix. * ace/OS.i (exit): In WIN32 when the process exits through an ExitProcess() call, some process resources (e.g., file handles) are freed before the static variable destructors are called. This results in an application error when tracing is enabled. Removing the ACE_TRACE call in ~ACE_Event_Handler seems to fix this. Thanks to Luca for this fix. * ace/OS: Fixed the implementation of semaphores for the POSIX port (POSIX lacks semaphores). The trick was to add a "waiters" field, along with the semaphore count. Thanks to John Bossom for reporting this. * examples/Threads/wfmo.cpp: Added a new test program that seems to indicate that the Win32 WaitForMultipleObjects() function can be called in multiple threads, all of which wait on the same set of HANDLEs. Note that the dispatching of the threads is relatively "fair" (i.e., everyone gets a chance to process the various HANDLEs as they become active). Thanks to Ari Erev for suggesting this and providing the initial code. * ace/Thread_Manager.h: Made the spawn_i() method virtual and moved it into the protected section of the class so that it can be over-ridden by subclasses. Thanks to Tim Harrison for suggesting this. Tue Jan 14 15:57:55 1997 Douglas C. Schmidt * ace/OS.h: Changed the default size of ACE_DEFAULT_TIMERS to _SC_TIMER_MAX (which is typically around 40 or so). Thanks to Stuart Powell for suggesting this. * tests/Timer_Queue_Test.cpp (main): Added some additional logic so that we can test the performance of the preallocated and non-preallocated ACE_Timer_Heap. * ace/Timer_Heap: Added a new "preallocate nodes" mechanism to the ACE_Timer_Heap. If this is enabled by the constructor, then we preallocate as many ACE_Timer_Nodes as there are slots in the heap. This allows us to completely remove the need for dynamic memory allocation, which is important for real-time systems. * ace/Thread_Manager.cpp (remove_thr): Optimized the code just a tad by decrementing the current_count_ *first*. Thanks to Per Andersson for suggesting this. * ace/ReactorEx: Updated the implementation so that the handle_events() method now in fact *does* return the number of event handler's dispatched (i.e., the implementation matches the documentation...). Thanks to Hamutal Yanay for reporting this. * ace/Service_Repository.cpp (remove): Removed an extra call to ACE_OS::dlclose(). This is already being called in the destructor of ACE_Service_Record. Thanks to Karlheinz for reporting this. * man: Updated all the nroff and html documentation. * ace/Timer_Heap: Implemented the spiffy new timer cancellation algorithm that requires only O(log N) time to remove a timer from the ACE_Timer_Heap. This is about 50 to 100 times faster than using the ACE_Timer_List implementation. Tue Jan 14 21:01:36 1997 David L. Levine * ace/OS.h: Replace "Linux" preprocessor symbol with "linux". Mon Jan 13 17:57:50 1997 Douglas C. Schmidt * ace/Synch: Added lock() accessor methods to both ACE_Process_Semaphore and ACE_Process_Mutex. Thanks to Hamutal Yanay for suggesting this. * ace/config-mvs.h: Added a #define for ACE_HAS_GETPAGESIZE. Thanks to Chuck Gehr for this information. * ace/LSOCK_Stream.h: Added a new typedef for PEER_ADDR that is associated with ACE_UNIX_Addr. Thanks to Mark Rabotnikov for suggesting this. Mon Jan 13 22:24:09 1997 David L. Levine * ace/OS.h: Added #undefs of sigemptyset and sigfillset on Linux when __OPTIMIZE__ is enabled. Yes, the system header on Linux really #defines them when optimizing! Thanks to an anonymous ACE user for pointing this out. * tests/tests_config.h: Dropped ACE_MAX_ITERATIONS back to 10. Sun Jan 12 16:59:52 1997 Douglas C. Schmidt * ace/Timer_List.cpp (schedule): Cleanup the code so that (1) timer_id never == -1 (in order to distinguish it from error return values and (2) so that we avoid an unnecessary check for operator new failure. * ace/OS.h: Added a new #define called ACE_DEFAULT_MAX_TIMERS, which specifies the maximum number of ACE_Event_Handlers supported by ACE_Timer_Heap. * ace/Proactor.cpp (ACE_Proactor): Updated the allocation of ACE_Timer_Queue so that it really points to an ACE_Timer_List by default. Naturally, this can be overridden by users. * ace/ReactorEx.cpp (open): Updated the allocation of ACE_Timer_Queue so that it really points to an ACE_Timer_List by default. Naturally, this can be overridden by users. * ace/Reactor.cpp (open): Updated the allocation of ACE_Timer_Queue so that it really points to an ACE_Timer_List by default. Naturally, this can be overridden by users. * ace: Added two new classes called ACE_Timer_List and ACE_Timer_Heap, which derive from ACE_Timer_Queue. ACE_Timer_List is essentially the old behavior of ACE_Timer_Queue, i.e., it uses an implementation of a linked list of ACE_Timer_Nodes. ACE_Timer_Heap, on the other hand, uses a heap-based callout queue, which is more appropriate for certain real-time applications. * ace/Timer_Queue: Revised the ACE_Timer_Queue implementation so that it's now an abstract base class with most of the implementation details pushed into the ACE_Timer_List and ACE_Timer_Heap subclasses. * ace/Timer_Queue.h: Made all the ACE_Timer_Queue methods public so that we can override them in a subclass (e.g., the new ACE_Timer_Heap). * examples/Logger/Acceptor-server/server_loggerd.cpp: Fixed this example application so that it only uses a single Reactor (the REACTOR::instance()) rather than two Reactors. Thanks to Sandro Doro for reporting this. * netsvcs/lib/Logging_Strategy.cpp: Fixed the #include of fstream.h and iostream.h to use the '<' '>' notation rather than the '"' and '"' notation. This avoids problems with running "make depend". Thanks to Rino Simioni for reporting this fix. Sun Jan 12 18:20:49 1997 David L. Levine * ace/ACE.cpp (round_to_pagesize): fixed typo in reference to ACE::pagesize_. * ace/ACE.cpp: initialize ACE::pagesize_ to 0. * ace/config-irix*.h and config-win*.h: removed ACE_PAGE_SIZE definition because these platforms no longer use it. * tests/UNIX*.conf and Win32server.conf: replaced net_svcs with netsvcs. Sat Jan 11 15:11:28 1997 Douglas C. Schmidt * ace/OS.i (thr_setprio): The POSIX implementation of ACE_OS:thr_setprio did not set the priority. It calls: pthread_setschedparam( thr_id, &policy, ¶m ) and then does prio = param.sched_priority. instead of param.sched_priority = prio; This is now fixed. Thanks to John Bossom for reporting this. * ace/config-irix*.h: Modified all the IRIX config files to use the new ACE_HAS_GETPAGESIZE feature since this is necessary to differentiate between IRIX and IRIX64. Thanks to Fred LaBar for reporting this. * ace/ACE.cpp: Modified the round_to_pagesize() so that if a config.h file enables ACE_HAS_GETPAGESIZE then we use that function in preference to the value in config.h. Thanks to Fred LaBar for suggesting this. * ace/ACE.cpp: Modified the round_to_pagesize() so that on platforms that allow the page size to be obtained dynamically we'll get that rather than replying on what it set in the config.h file. We'll cache this value in a static variable to speedup searches. Thanks to James Mansion for suggesting this. * apps/Gateway/Gateway: Finished adding support for thread-safe reference counting to the uses of ACE_Message_Block. * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: Replaced the use of ACE_MT_SYNCH with ACE_SYNCH so that this will compile correctly on non-MT platforms. Fri Jan 10 12:38:42 1997 Douglas C. Schmidt * Added a COPYING file that explicitly states the copyright status of ACE. * ace/config-win32-msvc4.x.h and ace/config-winnt-4.0-msvc4.x.h: By default, we'll revert to *not* enabling ACE_HAS_TEMPLATE_TYPEDEFS for MSVC++ 4.2, even though this is well-support by the compiler since it breaks some application code that expects to use 3 template parameters for ACE_Svc_Handler<>. The "fix" is to use the ACE_SOCK_STREAM macros (rather than using the "ACE_SOCK_Stream, ACE_INET_Addr" tuple) in order to achieve portability in either case. Thanks to Karlheinz for pointing out the need for backwards compatibility. Wed Jan 8 01:00:05 1997 Douglas C. Schmidt * tests/Message_Block_Test.cpp: Enhanced the torture test of the ACE_Message_Block so that it stresses the reference counting implementation in a multi-threaded environment. Wed Jan 08 10:26:45 1997 David L. Levine * ace/Message_Block.cpp (~ACE_Data_Block): assigned 0 to allocator_strategry_ after deleting it; fixed template specializations (for g++) by using macros instead of class names; commented out template specializations because Service_Record.cpp already has them, and they should only appear once in the library in order to avoid link clashes * ace/Service_Object.cpp (ACE_Service_Object): reordered initializations in constructor * ace/Service_Record.cpp (ACE_Service_Record): reordered initializations in constructor * ace/config-linux-lxpthreads.h: added ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS, thanks to James CE Johnson for tracking down this problem and testing the fix. Tue Jan 7 13:03:25 1997 Douglas C. Schmidt * ace/Message_Block: Continued to improve the ACE_Message_Block/ACE_Data_Block implementation. * ace/Message_Block: Added a new constructor to ACE_Message_Block that takes an ACE_Data_Block * and "owns" it. Thanks to Tim for this idea. * ace/Log_Msg.cpp: Now that we've prevented signal handlers from occurring within critical sections of ACE_Log_Msg::log() we don't need to use the ACE_Recursive_Thread_Mutex anymore. Instead, we just need ACE_Thread_Mutex. * ace/Log_Msg.cpp (log): Added an ACE_Sig_Guard to the block in ACE_Log_Msg::log() that acquires the mutex that serializes output. This prevents nasty problems with recursive to ACE_Log_Msg::log() from within signal handlers. * ace/Service_Config.cpp (end_reactor_event_loop): Added a timeout of ACE_Time_Value::zero to the ACE_Reactor::notify() method when called in the ACE_Service_Config::end_reactor_event_loop(). This prevents the Reactor from blocking indefinitely if there's no longer a thread to receive from the notification pipe. * netsvcs/clients/Naming/Dump_Restore: Removed the vestigal nametest.cpp and nametest.h files. I'm not sure why they were still there, but they shouldn't have been! * ace/Synch.i (remove): this->owner_ should be set to -1 before calling this->release(). Thanks to Per Andersson for suggesting this. * ace/Thread_Manager.cpp (exit): Added a flag called "do_thr_exit" to the ACE_Thread_Control::exit() method. This controls whether we call ACE_OS::thr_exit() after removing the thread from the Thread Manager's internal table. This is necessary to work around pthread bugs on certain platforms (e.g., AIX and Linux). * ace/Synch.h: Removed the ACE_Recursive_Thread_Mutex::set_nesting() method since this isn't being used and is potentially dangerous. Thanks to Per Andersson for suggesting this. * ace/XtReactor: Updated the XtReactor so that it uses the next internal Reactor implementation. Thanks to Mark Rabotnikov for reporting this. * ace/Task.i: Updated the grp_id(int) method to cache the group id in the task and then set it in the Thread_Manager, if there is one. Thanks to Hamutal Yanay for suggesting this. * ace/Log_Record.h: Updated the ACE_Log_Record class to use the new ACE_MAXLOGMSGLEN macro. * ace/OS.h: Added a new #define called ACE_MAXLOGMSGLEN. By default this is 4k. However, you can reset it in the config.h file if you'd like to increase or decrease the size. Thanks to Anthony McConnell for suggesting this. * examples/Threads/tss[12].cpp: Tidied up the tss1.cpp and tss2.cpp examples and improved the comments. Thanks to Luca for suggesting this. * ace/Service_Object.cpp (fini): Added the "virtual" keyword to the new destructor of ACE_Service_Type. Thanks to David for reporting this. * ace/Message_Block.i: Rearranged the order of the ACE_Data_Block and ACE_Message_Block locking_strategy() methods so that they'd be defined as inline before being used. Thanks to David for reporting this. Mon Jan 6 16:46:06 1997 Douglas C. Schmidt * ace/Service_Manager.cpp (fini): Only try to remove the ACE_Service_Manager from the Reactor if it's actually been registered in the first place (i.e., if it's get_handle() method does not return ACE_INVALID_HANDLE). * netsvcs/servers/svc.conf: Changed the name of the net services .so file from libnet_svcs to netsvcs so that it will work correctly with our new "cross-platform" svc.conf ACE::ldfind() strategy. Thanks to Marius Kjeldahl for reporting this. * ace/Reactor.cpp (find): Added a strategic break and a check for handle_in_range(). Thanks to Tim for this help! * netsvcs/clients/Naming/Client/svc.conf: Removed the "lib" part from the executable shared object file names in the svc.conf file so that it will work with the new "cross-platform" svc.conf ACE::ldfind() strategy. Thanks to Marius Kjeldahl for reporting this. * ace/Service_Record.cpp (fini): Added an extra assignment to a temporary const void *obj to avoid problems with MSVC++ and it's cast mechanism. * ace/ReactorEx.h: Added a default parameter to ACE_ReactorEx::notify(). Thanks to Tim for noticing this. Sun Jan 5 10:48:23 1997 Douglas C. Schmidt * tests: Added a new test for ACE_Message_Block, which is called Message_Block_Test.cpp (no surprise there ;-)). This test exercises the reference counting mechanisms. * ace/Message_Block.h: Made the destructors for ACE_Message_Block and ACE_Data_Block virtual, so that these classes can be subclassed and ACE_Message_Blocks can delete these subclasses (either via release() or delete). Thanks to Tilo Christ for suggesting this. * ace/Message_Block.cpp: Modified the implementation of ACE_Message_Block/ACE_Data_Block so that we always create an allocator_strategy_. By default, this strategy will be ACE_Allocator_Adapter >; This greatly simplifies the code. * ace/Message_Block.h: It's now possible to assign a Message_Block's priority when you create it. * ace/Reactor: Sped things up some more by merging the Reactor's any_ready() and fill_in_ready() methods together. This reduces redundant computations. * ace/Reactor: Changed the name of ACE_Reactor::detach() to ACE_Reactor::remove_handler_i() and changed the name of ACE_Reactor::attach() to ACE_Reactor::register_handler_i(). This is more consistent with the other naming schemes. * ace/Reactor.cpp: Reworked the implementation of the Handler Repository's unbind() method in order to simplfy the logic. Also merged in all the Reactor's detach() functionality into the unbind() method in order to localize all the handler removal processing. * ace/Reactor[Ex].cpp: Added more descriptive errno entries for failed operations in the handler repository. * ace/Reactor.cpp: Modified the implementation of the Handler Repository's bind() method so that it reports an error if you try to register an Event_Handler for an invalid HANDLE. * ace/Reactor.cpp: Reimplemented the internals of the Reactor to prepare for the upcoming merge of the Reactor and ReactorEx to use a single code base. * ace/Timer_Queue.cpp: Modified the behavior of the expire() methods so that they return the number of ACE_Event_Handlers whose handle_timeout() method was called. Sat Jan 4 11:47:05 1997 Douglas C. Schmidt * ace/Reactor.h: Removed the #ifdefs for ACE_HAS_POLL. This will be recast as a strategy in subsequent implementations. * ace/Reactor.cpp: Added a new call, ACE_Handler_Repository::handle_in_range(), which checks to make sure that the HANDLE is within the range of 0 .. max_handlep1_. This factors out some redundant code. * ace/Reactor.cpp: Sped up the performance of the Reactor by removing redundant calls to ACE_Handler_Repository::invalid_handle() and ACE_Handler_Repository::find(). * tests/Reactors_Test.cpp: Added a test for the new Reactor::notify() method with timeouts. * examples/Reactor/Misc/notification.cpp (svc): Added a test for the new Reactor::notify() method with timeouts. * ace/Reactor[Ex]: Modified the Reactor and ReactorEx so that they use timed send() operations for their notify() methods. This makes it possible for users to bound the amount of time they're willing to wait to try and notify the Reactor. This is mostly useful to avoid infinite blocking if there is congestion in the Reactor's notification mechanism. * ace/ACE.cpp: Added a new timed send() method that uses the write() system call on UNIX and the socket send() call on Win32. This new method is used in the new ACE_Reactor::notify() method, which now supported timed notifications. * ace/Reactor.cpp (ACE_Handler_Repository): To simplify the code and reduce unnecessary #ifdefs, I've merged the max_handlep1_ and cur_size_ fields (which are now called max_handlep1_). Fri Jan 3 10:47:15 1997 Douglas C. Schmidt * ace: Replaced all uses of "delete mb" with mb->release (); * ace/Stream_Modules.cpp: Replaced the use of explicit bit twiddling with the ACE_BIT* macros. * ace/Message_Block.cpp: Make sure that we use the allocator_strategy_ to create the memory for the reference count since this may need to go into shared memory if that's the memory pool where the Message_Block allocations are coming from. * ace/OS.h: Added two new macros, ACE_ALLOCATOR_RETURN and ACE_ALLOCATOR, which are similar to ACE_NEW_RETURN and ACE_NEW, except that these * ace/Message_Block.cpp (release): Make sure to "delete this" outside the scope of the locking_strategy_. * ace/Service_Object.cpp: Added a destructor to ACE_Service_Type. Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for suggesting this. * ace/Service_Object.i: Be smarter about how we reassign the name_ pointer, i.e., delete the old one and make a copy. Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting this. * ace/Module.cpp (open): Rearranged the assignments to reader_q->mod_ and writer_q->mod_ so that we don't try to initialize through NULL pointers. Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting this. * ace/Service_Record.cpp (ACE_Service_Record): Initialized name_ to NULL so that the following change works correctly now. Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting this. * ace/Service_Record.i (name): Make sure to delete [] (char *) this->name_ before allocating a new one. Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting this. * ace/Message_Block: Reworked the reference counting implemention so that reference counts are shared correctly amongst their various owners. This requires making a deep copy the "header" portion, but a shallow copy of the "data." * ace/Message_Block.cpp (ACE_Message_Block): Updated all three ACE_Message_Block constructors so that they all call the init() method. This centralizes all the initialization logic in one place. Thu Jan 2 00:42:21 1997 Douglas C. Schmidt * ace/Message_Block.cpp (ACE_Message_Block): Make sure to set the cont_ field to 0 after "releasing" it so that we don't mistakenly think it's still around later on. This problem arose in the ACE_Message_Queue::close() method, which was trying to count the number of bytes being freed. * ace/Message_Queue.cpp (close): Fixed a subtle bug where we weren't actually deleting messages from the ACE_Message_Queue::close() routine. This should work now... * ace/Message_Queue.cpp (close): Replaced the use of "delete mb" with "mb->release()" since the Message_Blocks are now reference counted. * ace/Message_Block: Enhanced the reference counting scheme so that you can increment and decrement the count by an arbitrary amount. This is particular useful when you know you'll be sending the same Message_Block to N consumers. * ace/Singleton: The dump() must be used same as instance() (without supplying an object) so it must be declarated *static*, i.e., static void dump (void); Thanks to Sandro Doro for reporting this. * examples/ASX/Event_Server: Completely rewrote and retested the ACE Event Server example. The new code is *much* easier to understand, has many more comments, is more robust, and compiles much faster since I removed many of the templates. * examples/ASX/Event_Server/Tranceiver/tranceiver.cpp: Fixed the tranceiver so that it shuts down correctly when the Event_Server exits. * examples/Connection/non_blocking/CPP-connector.cpp: Fixed a problem where we were trying to select() on ACE_STDIN on Win32. Naturally, this doesn't work, so we used the ACE::register_stdin_handler() to fix this. Thanks to Samuel_Bercovici for reporting this. * examples/ASX/Event_Server/Event_Server/Options: Changed the Options class to be a Singleton... * ace/Task.h: Added "const" method qualifier to accessor methods like is_reader() and is_writer(). Wed Jan 1 00:10:47 1997 Douglas C. Schmidt * ace/Message_Block: Added a new static release() method that behaves like the non-static method release(), except that it checks if is 0. This is similar to CORBA::release(), which is useful if you want to eliminate lots of checks for NULL pointers before calling release() on them. * Updated all places in ACE where we use ACE_Event_Handler::READ_MASK when we should be using ACE_Event_Handler::ACCEPT_MASK. * examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp: Changed the name of the acceptor class from Handle_Thr_Stream to Handle_Thr_Acceptor, which is more accurate. * ace/Reactor: Since we've now got an ACE_Event_Handler::ACCEPT_MASK (intended primarily to accept connections asynchronously using Win32 overlapped I/O) we can now use this with the ACE_Reactor, as well. In particular, any time that we are registering a "passive-mode" socket acceptor we can now specify ACE_Event_Handler::ACCEPT_MASK. This is much more intuitive than using the READ_MASK (which never made any sense...). The ACE_Reactor now treats the ACCEPT_MASK as a READ_MASK internally, so you can still use READ_MASK if you'd like (i.e., this change doesn't break any existing code). * ace/Event_Handler: Changed "get_priority" and "set_priority" to simply "priority(void)" and "priority(int)" to be more consistent with other parts of ACE. * apps/Gateway/Gateway: Updated the Gateway so that the concurrency strategies can now be specified on the command-line (or in the svc.conf file), rather than being determined at compile-time. This is much more flexible. See the ./apps/Gateway/Gateway/README file for details. * apps/Gateway/Gateway: Verified that all the multi-threading strategies still work. * ace/Message_Block.cpp (ACE_Message_Block): Make sure that we "release" the continuation field, rather than delete it, since its reference count may be > 1. * ace/Log_Msg.cpp (log): Change the abort_prog logic a bit so that we always print a message to stderr if we're exiting, regardless... Thanks to David Levine for pointing this out. * apps/Gateway/Gateway: Moved all of the configuration file parsing logic *outside* of the Event_Channel into the Gateway class so that we wouldn't have unnecessary dependencies. * apps/Gateway/Gateway: Redesigned the Gateway so that the Proxy_Handlers (i.e., the Consumer_Proxy and Supplier_Proxy) most of their work to the Event_Channel. This "lightweight proxy" design is an improvement since it is now possible to emulate the COS Event Channel semantics within the Event_Channel "kernel." * Happy new year! Let's start a new ChangeLog to celebrate the new year.
