- 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)
* Implement oversize_threshold, which uses a dedicated arena for allocations crossing the specified threshold to reduce fragmentation.
* Add extents usage information to stats.
* Log time information for sampled allocations.
* Support 0 size in sdallocx.
* Output rate for certain counters in malloc_stats.
* Add configure option --enable-readlinkat, which allows the use of readlinkat over readlink.
* Add configure options --{enable,disable}-{static,shared} to allow not building unwanted libraries.
* Add configure option --disable-libdl to enable fully static builds.
* 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)
* opt.oversize_threshold
* stats.arenas.<i>.extent_avail
* stats.arenas.<i>.extents.<j>.n{dirty,muzzy,retained}
* stats.arenas.<i>.extents.<j>.{dirty,muzzy,retained}_bytes
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:
* 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)
