Fri Apr 13 14:50:51 2007 Google Inc. <opensource@google.com> * google-perftools: version 0.90 release * (As the version-number jump hints, this is a major new release: almost every piece of functionality was rewritten. I can't do justice to all the changes, but will concentrate on highlights.) *** USER-VISIBLE CHANGES: * Ability to "release" unused memory added to tcmalloc * Exposed more tweaking knobs via environment variables (see docs) * pprof tries harder to map addresses to functions * tcmalloc_minimal compiles and runs on FreeBSD 6.0 and Solaris 10 *** INTERNAL CHANGES: * Much better 64-bit support * Better multiple-processor support (e.g. multicore contention tweaks) * Support for recent kernel ABI changes (e.g. new arg to mremap) * Addition of spinlocks to tcmalloc to reduce contention cost * Speed up tcmalloc by using __thread on systems that support TLS * Total redesign of heap-checker to improve liveness checking * More portable stack-frame analysis -- no more hard-coded constants! * Disentangled heap-profiler code and heap-checker code * Several new unittests to test, e.g., thread-contention costs * Lots of small (but important!) bug fixes: e.g., fixing GetPC on amd64 *** KNOWN PROBLEMS: * CPU-profiling may crash on x86_64 (64-bit) systems. See the README * Profiling/heap-checking may deadlock on x86_64 systems. See README git-svn-id: http://gperftools.googlecode.com/svn/trunk@28 6b5cf1ce-ec42-a296-1ba9-69fdba395a50
