[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 2.5, Package name: gperftools-2.5, Maintainer: cheusov

These tools are for use by developers so that they can create more
robust applications. Especially of use to those developing
multi-threaded applications in C++ with templates. Includes TCMalloc,
heap-checker, heap-profiler, and CPU-profiler.

Log message:
Changes 2.5:

Here are major changes since 2.4:

* we've moved to github!

* 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

* 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.

Log message:
Add SHA512 digests for distfiles for devel category

Issues found with existing distfiles:
No changes made to these distinfo files.

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
Update devel/gperftools to 2.4, patch provided by Jonathan Buschmann in PR 49625.

Changes from previous:

== 2.4 ==

+ enabled aggressive decommit option by default, significantly improve memory \ 
+ new ./configure flags for tcmalloc pagesize and tcmalloc allocation alignment.
+ Faster malloc/free, 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

== 2.3 ==

+ New experimental method for CPU profiling (only for Linux)
+ Most are fixes to pprof
+ Few other fixes, notably libunwind integration (selectable in configure step) \ 
and disabled on OSX & ppc64

== 2.2 ==

+ Support for mips/mips64/aarch64/ppc64-le
+ New method for capturing backtrace
+ More fixes
+ Fixes for Windows
+ Sources served by Google drive
