gperftools-2.15

This release has the following bug fixes:

  • Xiaowei Wang has pointed out the pthread linking issue on cmake on older glibcs (where -pthread is not implicit). See #1473 for more details.

  • Mikael Simberg and Tom "spot" Callaway have pointed out the missing symbols issue when linking PPC or i386 builds. #1474 has all the details.

Huge thanks to all contributors!

gperftools-2.14

gperftools 2.14 is out!

This release has the following set of notable changes:

  • Roman Geissler has contributed a fix to nasty initialization bug introduced in 2.13 (see github issue #1452 for one example where it fails).

  • spinlock delay support now has proper windows support. Instead of simply sleeping, it uses WaitOnAddress (which is basically windows equivalent of futexes). This improvement was contributed by Lennox Ho.

  • we now have basic QNX support (basic malloc + heap profiler) championed by Xiang.Lin. Thanks! Do note, however, that QNX doesn't provide SIGPROF ticks, so there will be no cpu profiler support on this OS.

  • Yikai Zhao has contributed several fixes to important corner cases of generic_fp stacktrace method.

  • several people have contributed v

gperftools-2.12

Brett T. Warden contributed one significant fix. After a change in the previous release, we installed broken pkg-config files. Brett noticed and fixed that. Huge thanks!

gperftools-2.13

gperftools 2.13 is out!

This release includes a few minor fixes:

  • Ivan Dlugos has fixed some issues with cmake and config.h defines.

  • 32-bit builds no longer require 64-bit atomics (which we wrongly introduced in 2.11 and which broke builds on some 32-bit architectures).

  • generic_fp backtracing method now uses robust address probing method. The previous approach had occasional false positives, which caused occasional rare crashes.

  • In some cases, MSVC generated TrivialOnce machine code that deadlocked programs on startup. The issue is now fixed.

gperftools-2.10

30 May 2022

gperftools 2.10 is out!

Here are notable changes:

  • Matt T. Proud contributed documentation fix to call Go programming language by it's true name instead of golang.
  • Robert Scott contributed debugallocator feature to use readable (PROT_READ) fence pages. This is activated by TCMALLOC_PAGE_FENCE_READABLE environment veriable.
  • User stdpain contributed fix for cmake detection of libunwind.
  • Natale Patriciello contributed fix for OSX Monterey support.
  • Volodymyr Nikolaichuk contributed support for returning memory back to OS by using mmap with MAP_FIXED and PROT_NONE. It is off by default and enabled by preprocessor define: FREE_MMAP_PROT_NONE. This should help OSes that don't support Linux-style madvise MADV_DONTNEED or BSD-style MADV_FREE.
  • Jingyun Hua has contributed basic support for LoongArc
