Changelog for libtcmalloc_minimal_debug4-2.15-2.4.x86_64.rpm :

* Sun Jan 28 2024 Dirk Müller - update to 2.15:
* Mikael Simberg and Tom \"spot\" Callaway have pointed out the missing symbols issue when linking PPC or i386 builds.
* 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.
* several people have contributed various improvements to our cmake build: Lennox Ho, Sergey Fedorov, Mateusz Jakub Fila. But do note that cmake build is still incomplete and best-effort.
* Julian Schroeder have fixed generic_fp incompatibility with ARM pointer auth.
* Mateusz Jakub Fila has contributed implementation of mallocinfo2 function (64-bit version of mallinfo).
* Lennox Ho has contributed the ability to disable malloc functions patching on windows when TCMALLOC_DISABLE_REPLACEMENT=1 environment variable is set.
* User poljak181 has contributed a fix to infinite recursion in some cases of malloc hooks (or user-replaced operator new) and MallocExtension::instance().
* Sergey Fedorov has contributed a fix to use MAP_ANON on some older OSes without MAP_ANONYMOUS.
* the way we detect working ucontext->pc extraction method was reworked and is now fully compile-time as opposed to config-time. This means no more duplication and mismatches between autoconf and cmake bits in this area.
* Fri Sep 29 2023 Paolo Stivanin - Update to 2.13:
* generic_fp backtracing method now uses robust address probing method. The previous approach had occasional false positives, which caused occasional rare crashes.
* fix pkg-config files
* we now support HEAPPROFILE_USE_PID and CPUPROFILE_USE_PID environment variables that force profile filenames to have pid appended. Which will be useful for some programs that fork for parallelism
* MPI detection has been extended
* Sun Jul 10 2022 Callum Farmer - Update to 2.10:
* Added debugallocator feature to use readable (PROT_READ) fence pages.
* fix for cmake detection of libunwind.
* fix for OSX Monterey support.
* support for returning memory back to OS by using mmap with MAP_FIXED and PROT_NONE
* basic support for LoongArch.
* Mon May 09 2022 Andreas Schwab - Enable use of libunwind on riscv64
* Sat May 22 2021 Callum Farmer - Follow shared library packaging policy
* Wed Mar 17 2021 Callum Farmer - Update to 2.9.1:
* usage of unsupportable linux_syscall_support.h has been removed from few places.
* Incorrect assertion failure was fixed that crashed tcmalloc if assertions were on and sized delete was used
* there is now better backtracing support for aarch64 and riscv x86-64 with frame pointers now also defaults to this new \"generic\" frame pointer backtracer.- Use golang version of pprof- Split doc into subpackage
* Fri Jan 08 2021 Andreas Schwab - Enable build on riscv64- No libunwind-coredump on powerpc
* Tue Jan 05 2021 Paolo Stivanin - Update to 2.8.1:
* previous release contained change to release memory without page heap lock, but this change had at least one bug that caused to crashes and corruption when running under aggressive decommit mode (this is not default). While we check for other bugs, this feature 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
* for compiling linux syscall support on i386 and recent GCCs
* test failures caused by new gcc 10 optimizations were fixed. Same change also fixed tests on clang.- Drop ppc64-fix-367fd5731a8c68225cb870aa656ea0ce677fe040.patch- Drop gcc-dont-clobber-rsp.patch
* Fri Sep 04 2020 Jan Engelhardt - Add ExclusiveArch declaration to specfile.- Trim some old specfile constructs.
* Fri Aug 02 2019 Martin Liška - Use FAT LTO objects in order to provide proper static library.
