New features: - - Implement the experimental {,r,s,d}allocm() API, which provides a superset - of the functionality available via malloc(), calloc(), posix_memalign(), - realloc(), malloc_usable_size(), and free(). These functions can be used - to allocate/reallocate aligned zeroed memory, ask for optional extra - memory during reallocation, prevent object movement during reallocation, - etc. - - Replace JEMALLOC_OPTIONS/JEMALLOC_PROF_PREFIX with MALLOC_CONF, which is - more human-readable, and more flexible. For example: - JEMALLOC_OPTIONS=AJP - is now: - MALLOC_CONF=abort:true,fill:true,stats_print:true - - Port to Apple OS X. Sponsored by Mozilla. - - Make it possible for the application to control thread-->arena mappings - via the "thread.arena" mallctl. - - Add compile-time support for all TLS-related functionality via pthreads - TSD. This is mainly of interest for OS X, which does not support TLS, but - has a TSD implementation with similar performance. - - Override memalign() and valloc() if they are provided by the system. - - Add the "arenas.purge" mallctl, which can be used to synchronously purge - all dirty unused pages. - - Make cumulative heap profiling data optional, so that it is possible to - limit the amount of memory consumed by heap profiling data structures. - - Add per thread allocation counters that can be accessed via the - "thread.allocated" and "thread.deallocated" mallctls. + - Implement the experimental {,r,s,d}allocm() API, which provides a superset + of the functionality available via malloc(), calloc(), posix_memalign(), + realloc(), malloc_usable_size(), and free().
