|
* google-perftools: initial release:
|
|
The google-perftools package contains some utilities to improve
|
|
and analyze the performance of C++ programs. This includes an
|
|
optimized thread-caching malloc() and cpu and heap profiling
|
|
utilities.

|
|
|
* google-perftools: version 0.2 release
|
|
* Use mmap2() instead of mmap(), to map more memory (menage)
|
|
* Do correct pthread-local checking in heap-checker! (maxim)
|
|
* Avoid overflow on 64-bit machines in pprof (sanjay)
|
|
* Add a few more GetPC() functions, including for AMD (csilvers)
|
|
* Better method for overriding pthread functions (menage)
|
|
* (Hacky) fix to avoid overwriting profile files after fork() (csilvers)
|
|
* Crashing bugfix involving dumping heaps on small-stack threads (tudor)
|
|
* Allow library versions with letters at the end (csilvers)
|
|
* Config fixes for systems that don't define PATH_MAX (csilvers)
|
|
* Confix fixes so we no longer need config.h after install (csilvers)
|
|
* Fix to pprof to correctly read very big cpu profiles (csilvers)
|
|
* Fix to pprof to deal with new commandline flags in modern gv's
|
|
* Better error reporting when we can't access /proc/maps (etune)
|
|
* Get rid of the libc-preallocate code (which could crash on some
|
|
systems); no longer needed with local-threads fix (csilvers)

* google-perftools: version 0.3 release
|
|
* Add missing errno include for one of the unittests (csilvers)
|
|
* Reduce tcmalloc startup memory from 5M to 256K (sanjay)
|
|
* Add support for mallopt() and mallinfo (sanjay)
|

|
|
|
|
* google-perftools: version 0.4 release
|
|
* Decrease fragmentation in tcmalloc (lefevere)
|
|
* Support for ARM in some of the thread-specific code (markus)
|
|
* Turn off heap-checker for statically-linked binaries, which
|
|
cause error leak reports now (etune)
|
|
* Many pprof improvements, including a command-line interface (jeff)
|
|
* CPU profiling now automatically affects all threads in linux 2.6.
|
|
(Kernel bugs break CPU profiling and threads in linux 2.4 a bit.)
|
|
ProfilerEnable() and ProfilerDisable() are deprecated. (sanjay)
|
|
* tcmalloc now correctly intercepts memalign (m3b, maxim)
|
|
* Syntax fix: added missing va_end()s. Helps non-gcc compiling (etune)
|
|
* Fixed a few coredumper bugs: race condition after PTRACE_DETACH,
|

ignore non-aligned stackframe pointers (markus, menage)
|
|
* 64-bit cleanup, especially for spinlock code (etune) and mmap (sanjay)
|
|
