Audrey Dutcher 86988bb5a8 background_thread: add fallback for pthread_create dlsym 
If jemalloc is linked into a shared library, the RTLD_NEXT dlsym call
may fail since RTLD_NEXT is only specified to search all objects after
the current one in the loading order, and the pthread library may be
earlier in the load order. Instead of failing immediately, attempt one
more time to find pthread_create via RTLD_GLOBAL.

Errors cascading from this were observed on FreeBSD 14.1.

msvc Unlike prof_sample which is supported only with profiling mode active, prof_threshold is intended to be an always-supported allocation callback with much less overhead. The usage of the threshold allows performance critical callers to change program execution based on the callback: e.g. drop caches when memory becomes high or to predict the program is about to OOM ahead of time using peak memory watermarks. 2025-01-29 18:55:52 -08:00

README 

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.
