Changelog for gperftools-devel-2.4-5.2.2.x86_64.rpm :
Sat Jan 10 13:00:00 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 14:00:00 2014 jengelhAATTinai.de

- Improve on RPM group classification

Mon Jun 16 14:00:00 2014 dvaleevAATTsuse.com
- fix issue 628 (gperftools 2.2 fails to build on powerpc)
missing_includes.patch

Mon May 19 14:00:00 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

* gperftools-glibc216.patch

* spinlock-rand.patch

* gperftools_use_older_autoconf.diff

Mon Aug 12 14:00:00 2013 cgardnerAATTsuse.com

gperftools can build for SLE10.

Tue Jul 30 14:00:00 2013 cgardnerAATTsuse.com
- gperftools 2.1, released 30 July 2013.

* fixes for building on newer platforms. Notably, there\'s now initial
support for x32 ABI (--enable-minimal only at this time))

* Some fixes for debug allocation on POWER/Linux

* new getNumericProperty stats for cache sizes

* added HEAP_PROFILER_TIME_INTERVAL variable (see documentation)

* added environment variable to control heap size (TCMALLOC_HEAP_LIMIT_MB)

* added environment variable to disable release of memory back to OS
(TCMALLOC_DISABLE_MEMORY_RELEASE)

* 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

* (issue 368) improved memory fragmentation when large chunks of
memory are allocated/freed
