- Add disable-test_prof_log_many_traces-test.patch in order to workaround https://github.com/jemalloc/jemalloc/issues/1477. - Update to version 5.2.0: New features: * Implement oversize_threshold, which uses a dedicated arena for allocations crossing the specified threshold to reduce fragmentation. (@interwq) * Add extents usage information to stats. (@tyleretzel) * Log time information for sampled allocations. (@tyleretzel) * Support 0 size in sdallocx. (@djwatson) * Output rate for certain counters in malloc_stats. (@zinoale) * Add configure option --enable-readlinkat, which allows the use of readlinkat over readlink. (@davidtgoldblatt) * Add configure options --{enable,disable}-{static,shared} to allow not building unwanted libraries. (@Ericson2314) * Add configure option --disable-libdl to enable fully static builds. (@interwq) * Add mallctl interfaces: * opt.oversize_threshold (@interwq) * stats.arenas.<i>.extent_avail (@tyleretzel) * stats.arenas.<i>.extents.<j>.n{dirty,muzzy,retained} (@tyleretzel) * stats.arenas.<i>.extents.<j>.{dirty,muzzy,retained}_bytes (@tyleretzel) Portability improvements: * Update MSVC builds. (@maksqwe, @rustyx) * Workaround a compiler optimizer bug on s390x. (@rkmisra) * Make use of pthread_set_name_np(3) on FreeBSD. (@trasz) * Implement malloc_getcpu() to enable percpu_arena for windows. (@santagada) * Link against -pthread instead of -lpthread. (@paravoid) * Make background_thread not dependent on libdl. (@interwq) * Add stringify to fix a linker directive issue on MSVC. (@daverigby) * Detect and fall back when 8-bit atomics are unavailable. (@interwq) * Fall back to the default pthread_create(3) if dlsym(3) fails. (@interwq) Optimizations and refactors: * Refactor the TSD module. (@davidtgoldblatt) * Avoid taking extents_muzzy mutex when muzzy is disabled. (@interwq) * Avoid taking large_mtx for auto arenas on the tcache flush path. (@interwq) * Optimize ixalloc by avoiding a size lookup. (@interwq) * Implement opt.oversize_threshold which uses a dedicated arena for requests crossing the threshold, also eagerly purges the oversize extents. Default the threshold to 8 MiB. (@interwq) * Clean compilation with -Wextra. (@gnzlbg, @jasone) * Refactor the size class module. (@davidtgoldblatt) * Refactor the stats emitter. (@tyleretzel) * Optimize pow2_ceil. (@rkmisra) * Avoid runtime detection of lazy purging on FreeBSD. (@trasz) * Optimize mmap(2) alignment handling on FreeBSD. (@trasz) * Improve error handling for THP state initialization. (@jsteemann) * Rework the malloc() fast path. (@djwatson) * Rework the free() fast path. (@djwatson) * Refactor and optimize the tcache fill / flush paths. (@djwatson) * Optimize sync / lwsync on PowerPC. (@chmeeedalf) * Bypass extent_dalloc() when retain is enabled. (@interwq) * Optimize the locking on large deallocation. (@interwq) * Reduce the number of pages committed from sanity checking in debug build. (@trasz, @interwq) * Deprecate OSSpinLock. (@interwq) * Lower the default number of background threads to 4 (when the feature is enabled). (@interwq) * Optimize the trylock spin wait. (@djwatson) * Use arena index for arena-matching checks. (@interwq) * Avoid forced decay on thread termination when using background threads. (@interwq) * Disable muzzy decay by default. (@djwatson, @interwq) * Only initialize libgcc unwinder when profiling is enabled. (@paravoid, @interwq) Bug fixes (all only relevant to jemalloc 5.x): * Fix background thread index issues with max_background_threads. (@djwatson, @interwq) * Fix stats output for opt.lg_extent_max_active_fit. (@interwq) * Fix opt.prof_prefix initialization. (@davidtgoldblatt) * Properly trigger decay on tcache destroy. (@interwq, @amosbird) * Fix tcache.flush. (@interwq) * Detect whether explicit extent zero out is necessary with huge pages or custom extent hooks, which may change the purge semantics. (@interwq) * Fix a side effect caused by extent_max_active_fit combined with decay-based purging, where freed extents can accumulate and not be reused for an extended period of time. (@interwq, @mpghf) * Fix a missing unlock on extent register error handling. (@zoulasc) Testing: * Simplify the Travis script output. (@gnzlbg) * Update the test scripts for FreeBSD. (@devnexen) * Add unit tests for the producer-consumer pattern. (@interwq) * Add Cirrus-CI config for FreeBSD builds. (@jasone) * Add size-matching sanity checks on tcache flush. (@davidtgoldblatt, @interwq) Incompatible changes: * Remove --with-lg-page-sizes. (@davidtgoldblatt) Documentation: * Attempt to build docs by default, however skip doc building when xsltproc is missing. (@interwq, @cmuellner) - Change URL of the project.
