* gthreadpool: set default max_unused_threads and max_idle_time valuesDan Winship2012-07-311-4/+5
| | | | | | | | | | | | | | GThreadPool defaulted to 0 for max_unused_threads (meaning thread-pool threads would exit immediately if there was not already another task waiting for them), and 0 for max_idle_time (meaning unused threads would linger forever, though this is only relevant if you changed max_unused_threads). However, GIOScheduler changed the global defaults to 2 and 15*1000, respectively, arguing that these were more useful defaults. And they are, so let's use them. https://bugzilla.gnome.org/show_bug.cgi?id=661767

* g_thread_new: never failRyan Lortie2011-10-131-1/+1
| | | | | Remove the GError argument from g_thread_new() and abort on failure. Introduce g_thread_try() for those who want to handle failure.
* thread: nuke the concept of 'joinable'Ryan Lortie2011-10-131-6/+7
| | | | | | | | And remove the 'joinable' argument from g_thread_new() and g_thread_new_full(). Change the wording in the docs. Clarify expectations for (deprecated) g_thread_create().
* Fix up some doc comments that referred to threads not being enabledDan Winship2011-10-051-1/+1

* Deprecate g_thread_init()Ryan Lortie2011-10-041-1/+0
| | | | | | | Move the last few things that needed thread-safe initialisation to a global ctor. https://bugzilla.gnome.org/show_bug.cgi?id=660744
* GMain, ThreadPool: embed GCond in structRyan Lortie2011-10-041-9/+5
| | | | | | | Use an embedded GCond and g_cond_init()/clear() instead of a pointer with g_cond_new() and _free(). https://bugzilla.gnome.org/show_bug.cgi?id=660739
* Add new thread creation APIMatthias Clasen2011-10-021-1/+1
| | | | | | | | | | Deprecate both g_thread_create functions and add g_thread_new() and g_thread_new_full(). The new functions expect a name for the thread. Change GThreadPool, GMainContext and GDBus to create named threads. https://bugzilla.gnome.org/show_bug.cgi?id=660635

* GThreadPool: cosmetic cleanupsMatthias Clasen2011-10-011-390/+419
| | | | | Mostly documentation and formatting trivial, but also add boolean return types to GError taking functions.
* Spelling fixesMatthias Clasen2011-08-291-2/+2
| | | | | Spelling fixes in comments and docs, provided by Kjartan Maraas in bug 657336.
* glib: Rewrite gatomic.[ch]Ryan Lortie2011-05-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - remove all inline assembly versions - implement the atomic operations using either GCC intrinsics, the Windows interlocked API or a mutex-based fallback - drop gatomic-gcc.c since these are now defined in the header file. Adjust Makefile.am accordingly. - expand the set of operations: support 'get', 'set', 'compare and exchange', 'add', 'or', and 'xor' for both integers and pointers - deprecate g_atomic_int_exchange_and_add since g_atomic_int_add (as with all the new arithmetic operations) now returns the prior value - unify the use of macros: all functions are now wrapped in macros that perform the proper casts and checks - remove G_GNUC_MAY_ALIAS use; it was never required for the integer operations (since casting between pointers that only vary in signedness of the target is explicitly permitted) and we avoid the need for the pointer operations by using simple 'void *' instead of 'gpointer *' (which caused the 'type-punned pointer' warning) - provide function implementations of g_atomic_int_inc and g_atomic_int_dec_and_test: these were strictly macros before - improve the documentation to make it very clear exactly which types of pointers these operations may be used with - remove a few uses of the now-deprecated g_atomic_int_exchange_and_add - drop initialisation of gatomic from gthread (by using a GStaticMutex instead of a GMutex) - update glib.symbols and documentation sections files Closes #650823 and #650935

| | | | | | | | | | | | | * glib/gthreadpool.c: Make sure g_thread_pool_stop_unused_threads() actually stops unused threads and global limits (like max idle time and max unused threads) can be set without creating a thread pool first. Fixed #335215 (patch from Chris Wilson). * tests/threadpool-test.c: Added two new tests, tests setting global limits before creating a thread pool. The second test makes sure unused threads are actually stopped when using the g_thread_pool_stop_unused_threads().

| | | | | | | | | | | * glib/gthreadpool.c: Updated the documentation to explain that when the maximum threads is > 1 the sort functionality is not 100% accurate due to the ramdom nature of the scheduler choosing which threads to execute. Fixes bug #334943. * tests/threadpool-test.c: Disabled the debugging by default and fixed the sort test to set the maximum threads to 1 to guarantee the thread entry function is called in order.

| | | | | | | | | | | | | | | 2006-01-17 Sebastian Wilhelmi <seppi@seppi.de> * glib/gthreadpool.c: To avoid deadlocks get rid of the settings G_LOCK. Use the unused_thread_queue lock instead. Change g_thread_pool_thread_proxy such that threads only wait on non-exlusive pools for at most a 1/2 second. Do not reorder tasks due to superfluous tasks. Global tasks wait at most for max-idle-time milliseconds. Make sure, that no task is woken up twice for the same event via a wakeup_serial. This fixes #324228. * tests/threadpool-test.c: Adapt test accordingly. Do not pass invalid NULL into the thread pools. This as well fixes #327290.

Also removed 'bound' from GThread struct. * gthreadpool.h, gthreadpool.c: Adapted GThreadPool to the above changes. GThreadPool lost the 'priority' and 'bound' members. g_thread_pool_new the 'stack_size', 'bound' and 'priority' parameters. * tests/mainloop-test.c, tests/thread-test.c, tests/threadpool-test.c: Adapted to the above changes.

* Until now every thread pool always had at least one tread waiting to avoidSebastian Wilhelmi2001-04-171-15/+53
| | | | | | | | | | | | | | 2001-04-17 Sebastian Wilhelmi <wilhelmi@ira.uka.de> * gthreadpool.c (g_thread_pool_thread_proxy): Until now every thread pool always had at least one tread waiting to avoid switching overhead in case a new task would be added soon after one finished. This however means a big waste of threads, if many mostly inactive thread pools are involved. Now such a waiting thread will only wait for half a second (This value is of course very randomly picked) and go to the global threadpool afterwards. MCVS: ----------------------------------------------------------------------
* Added documentation.Sebastian Wilhelmi2001-04-031-31/+213
| | | | | | | | | | | | 2001-04-03 Sebastian Wilhelmi <wilhelmi@ira.uka.de> * gthreadpool.c: Added documentation. * gthreadpool.c: The global thread pool now also is seperated for bound and unbound threads. Only threads with standard stack size go to the global pool. g_thread_pool_new now protects the global setup of inform_mutex etc. with a lock. Fixed some typos. Unlock the queue after g_thread_pool_wakeup_and_stop_all in the proxy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2000-11-21 Sebastian Wilhelmi <wilhelmi@ira.uka.de> * configure.in: Add a surrogate for thread priorities using PID niceness for systems with no thread priorities and different PIDs for threads of the same process (most notably: Linux). Define G_THREAD_USE_PID_SURROGATE in that case, as used by gthread-posix.c. Also make the system thread bigger by sizeof (long) to contain the thread's PID. * gfileutils.c: Include stdlib.h for mkstemp prototype. * gthread.c: Add priority range checks to the affected functions. * gthreadpool.c: Remove unused variable. * gthread-impl.c, gthread-posix.c, gthread-solaris.c: Removed g_thread_map_priority function in favour of the g_thread_priority_map array. Initialize the array with PRIORITY_{...}_VALUE, if available and interpolate beetween the bounds if .._NORMAL_.. and .._HIGH_.. are not available. * gthread-posix.c: If we should use the PID niceness as a surrogate for thread priorities (G_THREAD_USE_PID_SURROGATE is defined), then disable normal priority handling and use PIDs and setpriority() instead. Depends on the thread to write its PID into the place after the thread id right after thread creation.

| | | | | | | | | 2000-11-09 Sebastian Wilhelmi <wilhelmi@ira.uka.de> * gthreadpool.c: Don't take threads with other priorities into account as changing the priority is highly unportable.
