Changes in VERSION http://nxr.netbsd.org/rss/src/external/bsd/jemalloc/dist/VERSION en Copyright 2005 Java branches: 1.1.1; Initial revision /src/external/bsd/jemalloc/dist/VERSION - 1.1 Mon Mar 04 17:10:22 UTC 2019 christos Import jemalloc-5.3.0 (previous was 5.1.0) * 5.3.0 (May 6, 2022) This release contains many speed and space optimizations, from micro optimizations on common paths to rework of internal data structures and locking schemes, and many more too detailed to list below. Multiple percent of system level metric improvements were measured in tested production workloads. The release has gone through large-scale production testing. New features: - Add the thread.idle mallctl which hints that the calling thread will be idle for a nontrivial period of time. (@davidtgoldblatt) - Allow small size classes to be the maximum size class to cache in the thread-specific cache, through the opt.[lg_]tcache_max option. (@interwq, @jordalgo) - Make the behavior of realloc(ptr, 0) configurable with opt.zero_realloc. (@davidtgoldblatt) - Add 'make uninstall' support. (@sangshuduo, @Lapenkov) - Support C++17 over-aligned allocation. (@marksantaniello) - Add the thread.peak mallctl for approximate per-thread peak memory tracking. (@davidtgoldblatt) - Add interval-based stats output opt.stats_interval. (@interwq) - Add prof.prefix to override filename prefixes for dumps. (@zhxchen17) - Add high resolution timestamp support for profiling. (@tyroguru) - Add the --collapsed flag to jeprof for flamegraph generation.
