* Fixed issues with heap checker on PPC64 LE.Raphael Moreira Zinsly2014-04-121-1/+1
| | | | | | Fixed the wrapper for the syscall sys_clone and the test for heap checker on PPC64 LE. Both use the ODP structure, which is only used on BE architectures.
* issue-614: use tc_memalign in ReallocAfterMemalloc testAliaksey Kandratsenka2014-04-071-5/+3
| | | | | Because some OSes lack plain memalign. And we really need to test our implementation which is always available via tc_malloc.
* added tc_malloc_skip_new_handlerAliaksey Kandratsenka2014-04-011-0/+5
| | | | | | | | | | | | This is port of corresponding chromium change at: https://codereview.chromium.org/55333002/ Basic idea is that sometimes apps that use tc_set_new_mode in order to have C++ out-of-memory handler catch OOMs in malloc, need to invoke usual malloc that returns 0 on OOM. That new API is exactly for that. It'll always return NULL on OOM even if tc_new_mode is set to true.
* Fix getpc_test for PPC64v2 LEAdhemerval Zanella2014-03-291-2/+4
| | | | | | This patch fix the PPC64 guard to get the function address for PPC64v2. It removes the use of an indirection (to get the ODP text address), since the PPCv2 does not have function descriptors.

* issue-464: correctly handle realloc after memalign in debugallocAliaksey Kandratsenka2014-02-221-0/+18
| | | | | | | debug memalign is creating special header block to allow us to find real allocated block. And previous implementation of data copying wasn't taking that into account and was copying that "alignment header" into newly allocated block.
* issue-596: removed unused AtomicIncrement operationAliaksey Kandratsenka2014-01-041-114/+0
| | | | | There's no need for us to attempt to maintain Google's atomic ops code in era of C++11.
* issue-588: Fix profiler_unittest.cc fork()Aliaksey Kandratsenka2013-11-161-16/+20
| | | | | | | | | | | | | | As suggested by Hannes Weisbach. Call heap-profiler_unittest with the arguments 1 -2 (one iteration, 2 fork()ed children). Instead of running the test, the program crashes with a std::bad_alloc exception. This is caused by unconditionally passing the number-of-threads-argument (0 or positive for threads, negative for fork()s) in RunManyThreads(), thus allocating an array of pthread_t of size -2. Depending on the sign of the thread number argument either RunManyThreads or fork() should be called.
* issue-587: fix typos in unit test scriptsAliaksey Kandratsenka2013-11-164-4/+4
| | | | | | | | | | | | | | | As proposed by Hannes Weisbach. The argument will be garbled because of a misplaced brace, for example (heap-checker_unittest.sh): HEAP_CHECKER="${1:-$BINDIR}/heap-checker_unittest" which should be: HEAP_CHECKER="${1:-$BINDIR/heap-checker_unittest}" This unit test is used to check the binaries heap-checker_unittest and heap-checker_debug_unittest. With the typo, the executable heap-checker_debug_unittest is never actually run.
* issue-584: added license note to files without explicit licenseAliaksey Kandratsenka2013-11-094-0/+14
| | | | | As suggested at corresponding chromium issue discussion it's seemingly sufficient to simply refer to project-wide LICENSE file.

* issue-556: drop malloc limit at the end of page_heap_testalkondratenko@gmail.com2013-07-261-0/+7
| | | | | | | | | Which otherwise causes somewhat weird stack overflow on release windows builds. git-svn-id: http://gperftools.googlecode.com/svn/trunk@230 6b5cf1ce-ec42-a296-1ba9-69fdba395a50
* issue-552: Fix page_heap_test for system with different page sizealkondratenko@gmail.com2013-07-261-1/+4
| | | | | | | | | | | | | | | | | | | | This is patch by Adhemerval Zanella. PowerPC uses 64K page size instead of 4k for x86 and x86_64. It makes the page_heap_test fails because the following test: static bool HaveSystemRelease = TCMalloc_SystemRelease(TCMalloc_SystemAlloc(kPageSize, NULL, 0), kPageSize); will always fail if kPageSize is less than getpagesize() (the default configuration). The following patch fixes it by trying to allocate/deallocate an entire page instead. git-svn-id: http://gperftools.googlecode.com/svn/trunk@228 6b5cf1ce-ec42-a296-1ba9-69fdba395a50
* issue-553: Fix syscall wrapper for PowerPCalkondratenko@gmail.com2013-07-261-2/+23
| | | | | | | | | | | | | | | | | | | | | | This is patch by Adhemerval Zanella. * src/stacktrace_powerpc-inl.h: It is just a cleanup for the stacktrace functions for PowerPC. The idea is to simplify the code. * src/tests/heap-checker_unittest.cc: Handles the PPC64 function descriptor correctly in malloc tracers. Different from other architecture, for PPC64 the address returned in function pointers are the ODP entry, not the symbol address in .text segment. This leads the comparison bogus, since it will compare a ODP entry with a .text address. * src/heap-checker.cc: Add support for PPC in ptrace. * src/base/elfcore.h: Likewise. * src/base/linuxthreads.cc: Fix the thread creation using the clone wrapper. * src/base/linux_syscall_support.h: Various fixes for PPC32 and PPC64: fixes the kernel_stat[64] struct layout, and sys_clone and sys_socket implementation. git-svn-id: http://gperftools.googlecode.com/svn/trunk@227 6b5cf1ce-ec42-a296-1ba9-69fdba395a50

* issue-506: fixed bogus unit test failurealkondratenko@gmail.com2013-03-111-2/+13
| | | | | | | | | | | Looks like my version of GCC is aware that free(malloc(X)) is a no-op. So it optimizes that away completely ignoring simple fact that we're observing malloc hooks invocations. By adding check that malloc succeeded we force gcc to actually preserve that malloc call. git-svn-id: http://gperftools.googlecode.com/svn/trunk@208 6b5cf1ce-ec42-a296-1ba9-69fdba395a50

* issue-443: Increase the number of objects transferred between thread cache ↵chappedm@gmail.com2013-03-101-0/+68
| | | | | | | | | | | | | and central free list This fix is a result of a performance degradation observed in multi-threaded programs where large amounts of memory (30GB) are consumed, released by a pool of threads in a cyclic manner. This was mainly due to the amount of time we were spending in the slow path consolidating memory between the thread cache and central free list. The default has been bumped up to 32768 and is now also controllable through the TCMALLOC_TRANSFER_NUM_OBJ environment setting. git-svn-id: http://gperftools.googlecode.com/svn/trunk@193 6b5cf1ce-ec42-a296-1ba9-69fdba395a50
