Pull the tcache-aware routing helpers out of arena into a layer that sits directly below the public malloc interface: arena_malloc -> malloc_dispatch_malloc arena_palloc -> malloc_dispatch_palloc arena_ralloc -> malloc_dispatch_ralloc arena_dalloc* -> malloc_dispatch_dalloc* arena_sdalloc* -> malloc_dispatch_sdalloc* arena_dalloc_promoted -> malloc_dispatch_dalloc_promoted The new module (malloc_dispatch.h, malloc_dispatch_inlines.h, src/malloc_dispatch.c) owns the tcache-vs-fall-through decision; the only consumer is jemalloc_internal_inlines_c.h. arena keeps a narrower arena_prof_demote() for the sampled-allocation demotion path.
jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: https://jemalloc.net/
