CHANGELOG - third_party/github.com/mjansson/rpmalloc - Git at Google

 1.2.1

 Split library into rpmalloc only base library and preloadable malloc wrapper library.

 Add arg validation to valloc and pvalloc.

 Change ARM memory barrier instructions to dmb ish/ishst for compatibility.

 Improve preload compatibility on Apple platforms by using pthread key for TLS in wrapper library.

 Fix ABA issue in orphaned heap linked list

 1.2

 Dual license under MIT

 Fix init/fini checks in malloc entry points for preloading into binaries that does malloc/free in init or fini sections

 Fixed an issue where freeing a block which had been realigned during allocation due to alignment request greater than 16 caused the free block link to be written in the wrong place in the block, causing next allocation from the size class to return a bad pointer

 Improve mmap 64KiB granularity enforcement loop to avoid excessive iterations

 Fix undersized adaptive cache counter array for large block in heap structure, causing potential abort on exit

 Avoid hysteresis in realloc by overallocating on small size increases

 Add entry point for realloc with alignment and optional flags to avoid preserving content

 Add valloc/pvalloc/cfree wrappers

 Add C++ new/delete wrappers


 1.1

 Add four cache presets (unlimited, performance priority, size priority and no cache)

 Slight performance improvement by dependent class index lookup for merged size classes

 Adaptive cache size per thread and per size class for improved memory efficiency, and release thread caches to global cache in fixed size batches

 Merged caches for small/medium classes using 64KiB spans with 64KiB large blocks

 Require thread initialization with rpmalloc_thread_initialize, add pthread hooks for automatic init/fini

 Added rpmalloc_usable_size query entry point

 Fix invalid old size in memory copy during realloc

 Optional statistics and integer overflow guards

 Optional asserts for easier debugging

 Provide malloc entry point replacements and automatic init/fini hooks, and a LD_PRELOAD:able dynamic library build

 Improve documentation and additional code comments

 Move benchmarks to separate repo, https://github.com/rampantpixels/rpmalloc-benchmark
