- 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...@sebesbefut.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.

Mon Sep 15 00:33:02 CEST 2014 - ro@suse.de
- set excludearch for s390 and s390x: not ported there
-------------------------------------------------------------------
Mon Jun 16 10:51:46 UTC 2014 - dvaleev@suse.com
- fix issue 628 (gperftools 2.2 fails to build on powerpc)
missing_includes.patch
-------------------------------------------------------------------
Mon May 19 15:39:40 UTC 2014 - cgardner@suse.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 15:49:12 UTC 2013 - cgardner@suse.com
- Fixed configure.ac to use older version of autoconf, so that
gperftools can build for SLE10.
-------------------------------------------------------------------
Tue Jul 30 17:44:01 UTC 2013 - cgardner@suse.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
