This regression was introduced + in 3.1.0 by the addition of the "arena..purge" mallctl. + +* 3.1.0 (October 16, 2012) + + New features: + - Auto-detect whether running inside Valgrind, thus removing the need to + manually specify MALLOC_CONF=valgrind:true. + - Add the "arenas.extend" mallctl, which allows applications to create + manually managed arenas. + - Add the ALLOCM_ARENA() flag for {,r,d}allocm(). + - Add the "opt.dss", "arena..dss", and "stats.arenas..dss" mallctls, + which provide control over dss/mmap precedence. + - Add the "arena..purge" mallctl, which obsoletes "arenas.purge". + - Define LG_QUANTUM for hppa. + + Incompatible changes: + - Disable tcache by default if running inside Valgrind, in order to avoid + making unallocated objects appear reachable to Valgrind. + - Drop const from malloc_usable_size() argument on Linux. + + Bug fixes: + - Fix heap profiling crash if sampled object is freed via realloc(p, 0). + - Remove const from __*_hook variable declarations, so that glibc can modify + them during process forking. + - Fix mlockall(2)/madvise(2) interaction. + - Fix fork(2)-related deadlocks. + - Fix error return value for "thread.tcache.enabled" mallctl. + +* 3.0.0 (May 11, 2012) + + Although this version adds some major new features, the primary focus is on + internal code cleanup that facilitates maintainability and portability, most + of which is not reflected in the ChangeLog. This is the first release to + incorporate substantial contributions from numerous other developers, and the + result is a more broadly useful allocator (see the git revision history for + contribution details). Note that the license has been unified, thanks to + Facebook granting a license under the same terms as the other copyright + holders (see COPYING). + + New features: + - Implement Valgrind support, redzones, and quarantine. + - Add support for additional platforms: + + FreeBSD + + Mac OS X Lion + + MinGW + + Windows (no support yet for replacing the system malloc) + - Add support for additional architectures: + + MIPS + + SH4 + + Tilera + - Add support for cross compiling. + - Add nallocm(), which rounds a request size up to the nearest size class + without actually allocating. + - Implement aligned_alloc() (blame C11). + - Add the "thread.tcache.enabled" mallctl. + - Add the "opt.prof_final" mallctl. + - Update pprof (from gperftools 2.0). + - Add the --with-mangling option. + - Add the --disable-experimental option. + - Add the --disable-munmap option, and make it the default on Linux. + - Add the --enable-mremap option, which disables use of mremap(2) by default. + + Incompatible changes: + - Enable stats by default. + - Enable fill by default. + - Disable lazy locking by default. + - Rename the "tcache.flush" mallctl to "thread.tcache.flush". + - Rename the "arenas.pagesize" mallctl to "arenas.page". + - Change the "opt.lg_prof_sample" default from 0 to 19 (1 B to 512 KiB). + - Change the "opt.prof_accum" default from true to false. + + Removed features: + - Remove the swap feature, including the "config.swap", "swap.avail", + "swap.prezeroed", "swap.nfds", and "swap.fds" mallctls. + - Remove highruns statistics, including the + "stats.arenas..bins..highruns" and + "stats.arenas..lruns..highruns" mallctls. + - As part of small size class refactoring, remove the "opt.lg_[qc]space_max", + "arenas.cacheline", "arenas.subpage", "arenas.[tqcs]space_{min,max}", and + "arenas.[tqcs]bins" mallctls. + - Remove the "arenas.chunksize" mallctl. + - Remove the "opt.lg_prof_tcmax" option. + - Remove the "opt.lg_prof_bt_max" option. + - Remove the "opt.lg_tcache_gc_sweep" option. + - Remove the --disable-tiny option, including the "config.tiny" mallctl. + - Remove the --enable-dynamic-page-shift configure option. + - Remove the --enable-sysv configure option. + + Bug fixes: + - Fix a statistics-related bug in the "thread.arena" mallctl that could cause + invalid statistics and crashes. + - Work around TLS deallocation via free() on Linux. This bug could cause + write-after-free memory corruption. + - Fix a potential deadlock that could occur during interval- and + growth-triggered heap profile dumps. + - Fix large calloc() zeroing bugs due to dropping chunk map unzeroed flags. + - Fix chunk_alloc_dss() to stop claiming memory is zeroed. This bug could + cause memory corruption and crashes with --enable-dss specified. + - Fix fork-related bugs that could cause deadlock in children between fork + and exec. + - Fix malloc_stats_print() to honor 'b' and 'l' in the opts parameter. + - Fix realloc(p, 0) to act like free(p). + - Do not enforce minimum alignment in memalign(). + - Check for NULL pointer in malloc_usable_size(). + - Fix an off-by-one heap profile statistics bug that could be observed in + interval- and growth-triggered heap profiles. + - Fix the "epoch" mallctl to update cached stats even if the passed in epoch + is 0. + - Fix bin->runcur management to fix a layout policy bug. This bug did not + affect correctness. + - Fix a bug in choose_arena_hard() that potentially caused more arenas to be + initialized than necessary. + - Add missing "opt.lg_tcache_max" mallctl implementation. + - Use glibc allocator hooks to make mixed allocator usage less likely. + - Fix build issues for --disable-tcache. + - Don't mangle pthread_create() when --with-private-namespace is specified. + +* 2.2.5 (November 14, 2011) + + Bug fixes: + - Fix huge_ralloc() race when using mremap(2). This is a serious bug that + could cause memory corruption and/or crashes. + - Fix huge_ralloc() to maintain chunk statistics. + - Fix malloc_stats_print(..., "a") output. + +* 2.2.4 (November 5, 2011) + + Bug fixes: + - Initialize arenas_tsd before using it. This bug existed for 2.2.[0-3], as + well as for --disable-tls builds in earlier releases. + - Do not assume a 4 KiB page size in test/rallocm.c. + +* 2.2.3 (August 31, 2011) + + This version fixes numerous bugs related to heap profiling. + + Bug fixes: + - Fix a prof-related race condition. This bug could cause memory corruption, + but only occurred in non-default configurations (prof_accum:false). + - Fix off-by-one backtracing issues (make sure that prof_alloc_prep() is + excluded from backtraces). + - Fix a prof-related bug in realloc() (only triggered by OOM errors). + - Fix prof-related bugs in allocm() and rallocm(). + - Fix prof_tdata_cleanup() for --disable-tls builds. + - Fix a relative include path, to fix objdir builds. + +* 2.2.2 (July 30, 2011) + + Bug fixes: + - Fix a build error for --disable-tcache. + - Fix assertions in arena_purge() (for real this time). + - Add the --with-private-namespace option. This is a workaround for symbol + conflicts that can inadvertently arise when using static libraries. + * 2.2.1 (March 30, 2011) Bug fixes:
