Changelog for libtcmalloc4-debuginfo-2.4-4.4.x86_64.rpm :

* Sat Jan 10 2015 cgardnerAATTsuse.com- gperftools 2.4, available 10 Jan 2015. Skipped version 2.3, release 7 Dec 2014. 2.3 changes included:
* ( issue 631 ) fixed debugallocation miscompilation on mmap-less platforms (courtesy of user iamxujian)
* ( issue 630 ) reference to wrong PROFILE (vs. correct CPUPROFILE) environment variable was fixed (courtesy of WenSheng He)
* pprof now has option to display stack traces in output for heap checker (courtesy of Michael Pasieka)
* ( issue 636 ) pprof web command now works on mingw
* ( issue 635 ) pprof now handles library paths that contain spaces (courtesy of user mich...AATTsebesbefut.com)
* ( issue 637 ) pprof now has an option to not strip template arguments (patch by jiakai)
* ( issue 644 ) possible out-of-bounds access in GetenvBeforeMain was fixed (thanks to user abyss.7)
* ( issue 641 ) pprof now has an option --show_addresses (thanks to user yurivict). New option prints instruction address in addition to function name in stack traces
* ( issue 646 ) pprof now works around some issues of addr2line reportedly when DWARF v4 format is used (patch by Adam McNeeney)
* ( issue 645 ) heap profiler exit message now includes remaining memory allocated info (patch by user yurivict)
* pprof code that finds location of /proc/pid/maps in cpu profile files is now fixed (patch by Ricardo M. Correia)
* ( issue 654 ) pprof now handles \"split text segments\" feature of Chromium for Android (patch by simonb)
* ( issue 655 ) potential deadlock on windows caused by early call to getenv in malloc initialization code was fixed (bug reported and fix proposed by user zndmitry)
* incorrect detection of arm 6zk instruction set support (-mcpu=arm1176jzf-s) was fixed. (Reported by pedronavf on old issue-493)
* new cpu profiling mode on Linux is now implemented. It sets up separate profiling timers for separate threads. Which improves accuracy of profiling on Linux a lot. It is off by default. And is enabled if both librt.f is loaded and CPUPROFILE_PER_THREAD_TIMERS environment variable is set. But note that all threads need to be registered via ProfilerRegisterThread. Changes for version 2.4~rc
* enabled aggressive decommit option by default. It was found to significantly improve memory fragmentation with negligible impact on performance. (Thanks to investigation work performed by Adhemerval Zanella)
* added ./configure flags for tcmalloc pagesize and tcmalloc allocation alignment. Larger page sizes have been reported to improve performance occasionally. (Patch by Raphael Moreira Zinsly)
* sped-up hot-path of malloc/free. By about 5% on static library and about 10% on shared library. Mainly due to more efficient checking of malloc hooks.
* improved accuracy of stacktrace capturing in cpu profiler (due to issue found by Arun Sharma). As part of that issue pprof\'s handling of cpu profiles was also improved.- Removed missing_includes.patch; incorporated upstream.
* Sun Sep 28 2014 jengelhAATTinai.de- Implement shlib packaging guidelines: split libraries- Improve on RPM group classification
* Sun Sep 14 2014 roAATTsuse.de- set excludearch for s390 and s390x: not ported there
* Mon Jun 16 2014 dvaleevAATTsuse.com- fix issue 628 (gperftools 2.2 fails to build on powerpc) missing_includes.patch
* Mon May 19 2014 cgardnerAATTsuse.com- gperftools 2.2, released 3 May 2014.
* issue 620 (crash on windows when c runtime dll is reloaded) was fixed
* a number of fixes for a number compilers and platforms. Notably Visual Studio 2013, recent mingw with c++ threads and some OSX fixes.
* we now have mips and mips64 support! (courtesy of Jovan Zelincevic, Jean Lee, user xiaoyur347 and others)
* we now have aarch64 (aka arm64) support! (contributed by Riku Voipio)
* there\'s now support for ppc64-le (by Raphael Moreira Zinsly and Adhemerval Zanella)
* there\'s now some support of uclibc (contributed by user xiaoyur347)
* google/ headers will now give you deprecation warning. They are deprecated since 2.0
* there\'s now new api: tc_malloc_skip_new_handler (ported from chromium fork)
* issue-557: added support for dumping heap profile via signal (by Jean Lee)
* issue-567: Petr Hosek contributed SysAllocator support for windows
* Joonsoo Kim contributed several speedups for central freelist code
* TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES environment variable now works
* configure scripts are now using AM_MAINTAINER_MODE. It\'ll only affect folks who modify source from .tar.gz and want automake to automatically rebuild Makefile-s. See automake documentation for that.
* issue-586: detect main executable even if PIE is active (based on patch by user themastermind1). Notably, it fixes profiler use with ruby.
* there is now support for switching backtrace capturing method at runtime (via TCMALLOC_STACKTRACE_METHOD and TCMALLOC_STACKTRACE_METHOD_VERBOSE environment variables)
* there is new backtrace capturing method using -finstrument-functions prologues contributed by user xiaoyur347
* few cases of crashes/deadlocks in profiler were addressed. See (famous) issue-66, issue-547 and issue-579.
* issue-464 (memory corruption in debugalloc\'s realloc after memallign) is now fixed
* tcmalloc is now able to release memory back to OS on windows (issue-489). The code was ported from chromium fork (by a number of authors).
* Together with issue-489 we ported chromium\'s \"aggressive decommit\" mode. In this mode (settable via malloc extension and via environment variable TCMALLOC_AGGRESSIVE_DECOMMIT), free pages are returned back to OS immediately.
* MallocExtension::instance() is now faster (based on patch by Adhemerval Zanella)
* issue-610 (hangs on windows in multibyte locales) is now fixed- Removed the following patches. All have either been incorporated upstream or are no longer applicable in current distros.
* gperftools_fix_multiple_install_headers.patch

* cpu profiler can now be switched on and off by sending it a signal (specified in CPUPROFILESIGNAL)
* (issue 491) fixed race-ful spinlock wake-ups
* (issue 496) added some support for fork-ing of process that is using tcmalloc
