was reverted. See github issue #1204 and issue #1227.
* stack traces depth captured by gperftools is now up to 254 levels
deep
* updated detection of program counter
* ProfilerGetStackTrace is now officially supported API for
libprofiler

- gperftools 2.5, available 12 March 2016.
See https://github.com/gperftools/gperftools/releases
* Bryan Chan has contributed s390x support
* stacktrace capturing via libgcc's _Unwind_Backtrace was implemented
(for architectures with missing or broken libunwind).
* "emergency malloc" was implemented. Which unbreaks recursive calls
to malloc/free from stacktrace capturing functions (such us glib'c
backtrace() or libunwind on arm). It is enabled by
- -enable-emergency-malloc configure flag or by default on arm when
- -enable-stacktrace-via-backtrace is given. It is another fix for a
number common issues people had on platforms with missing or broken
libunwind.
* C++14 sized-deallocation is now supported (on gcc 5 and recent
clangs). It is off by default and can be enabled at configure time
via --enable-sized-delete. On GNU/Linux it can also be enabled at
run-time by either TCMALLOC_ENABLE_SIZED_DELETE environment variable
or by defining tcmalloc_sized_delete_enabled function which should
return 1 to enable it.
* we've lowered default value of transfer batch size to 512. Previous
value (bumped up in 2.1) was too high and caused performance
regression for some users. 512 should still give us performance
boost for workloads that need higher transfer batch size while not
penalizing other workloads too much.
* Brian Silverman's patch finally stopped arming profiling timer
unless profiling is started.
* Andrew Morrow has contributed support for obtaining cache size of the
current thread and softer idling (for use in MongoDB).
* we've implemented few minor performance improvements, particularly
on malloc fast-path.
* issue that caused spurious profiler_unittest.sh failures was fixed.
* Jonathan Lambrechts contributed improved callgrind format support to
pprof.
* Matt Cross contributed better support for debug symbols in separate
files to pprof.
* Matt Cross contributed support for printing collapsed stack frame
from pprof aimed at producing flame graphs.
* Angus Gratton has contributed documentation fix mentioning that on
windows only tcmalloc_minimal is supported.
* Anton Samokhvalov has made tcmalloc use mi_force_{un,}lock on OSX
instead of pthread_atfork. Which apparently fixes forking
issues tcmalloc had on OSX.
* Milton Chiang has contributed support for building 32-bit gperftools
on arm8.
* Patrick LoPresti has contributed support for specifying alternative
profiling signal via CPUPROFILE_TIMER_SIGNAL environment variable.
* Paolo Bonzini has contributed support configuring filename for
sending malloc tracing output via TCMALLOC_TRACE_FILE environment
variable.
* user spotrh has enabled use of futex on arm.
* user mitchblank has contributed better declaration for arg-less
profiler functions.
* Tom Conerly contributed proper freeing of memory allocated in
HeapProfileTable::FillOrderedProfile on error paths.
* user fdeweerdt has contributed curl arguments handling fix in pprof
* Frederik Mellbin fixed tcmalloc's idea of mangled new and delete
symbols on windows x64
* Dair Grant has contributed cacheline alignment for ThreadCache
objects
* Fredrik Mellbin has contributed updated windows/config.h for Visual
Studio 2015 and other windows fixes.
* we're not linking libpthread to libtcmalloc_minimal anymore. Instead
libtcmalloc_minimal links to pthread symbols weakly. As a result
single-threaded programs remain single-threaded when linking to or
preloading libtcmalloc_minimal.so.
* Boris Sazonov has contributed mips compilation fix and printf misue
in pprof.
* Adhemerval Zanella has contributed alignment fixes for statically
allocated variables.
* Jens Rosenboom has contributed fixes for heap-profiler_unittest.sh
* gshirishfree has contributed better description for GetStats method.
* cyshi has contributed spinlock pause fix.
* Chris Mayo has contributed --docdir argument support for configure.
* Duncan Sands has contributed fix for function aliases.
* Simon Que contributed better include for malloc_hook_c.h
* user wmamrak contributed struct timespec fix for Visual Studio 2015.
* user ssubotin contributed typo in PrintAvailability code.
* build fix for Visual Studio.
* dynamic sized delete is now disabled by default. It turned out that
IFUNC relocations are not supporting our advanced use case on all
platforms and in all cases.
- Removed the following patches. All have either been incorporated
upstream or are no longer applicable in current distros.
* gperftools-fix_docdir.patch
* Sat Oct 31 2015 mpluskal@suse.com
- Update project and download url
- Tiny spec file cleanup with spec-cleaner
* Sat Jan 10 2015 cgardner@suse.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...@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.
* Sun Sep 28 2014 jengelh@inai.de
- Implement shlib packaging guidelines: split libraries
- Improve on RPM group classification
* Sun Sep 14 2014 ro@suse.de
- set excludearch for s390 and s390x: not ported there
* Mon Jun 16 2014 dvaleev@suse.com
- fix issue 628 (gperftools 2.2 fails to build on powerpc)
missing_includes.patch
* Mon May 19 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)

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

- 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))
