Add --with-jemalloc-prefix, which supports API mangling. Rename jemalloc_options-->malloc_options and jemalloc_message-->malloc_message.

#ifndef JEMALLOC_H_
#define JEMALLOC_H_
Clean up the manpage and conditionalize various portions according to how jemalloc is configured. Modify arena_malloc() API to avoid unnecessary choose_arena() calls. Remove unnecessary code from choose_arena(). Enable lazy-lock by default, now that choose_arena() is both faster and out of the critical path. Implement objdir support in the build system.

Revert "Use ffsl() in ALLOCM_ALIGN()." This reverts commit 722b370399fd6734de6781285ce9a0cffd547bdd. Unfortunately, glibc requires _GNU_SOURCE to be defined before including string.h, but there is no reliable way to get the prototype within jemalloc.h unless _GNU_SOURCE was already defined.
2012-04-05 06:24:01 +08:00
#include <limits.h>
Add {,r,s,d}allocm(). Add allocm(), rallocm(), sallocm(), and dallocm(), which are a functional superset of malloc(), calloc(), posix_memalign(), malloc_usable_size(), and free().
2010-09-18 06:46:18 +08:00
#include <strings.h>
Add release versioning support. Base version string on 'git describe --long', and provide cpp macros in jemalloc.h. Add the version mallctl.

Fix ALLOCM_LG_ALIGN definition. Fix ALLOCM_LG_ALIGN to take a parameter and use it. Apparently, an editing error left ALLOCM_LG_ALIGN with the same definition as ALLOCM_LG_ALIGN_MASK.

Replace JEMALLOC_ATTR with various different macros when it makes sense Theses newly added macros will be used to implement the equivalent under MSVC. Also, move the definitions to headers, where they make more sense, and for some, are even more useful there (e.g. malloc).

Make malloc_stats_print() a public symbol, and make it repeatedly callable. Incrementally merge tcache stats, so that malloc_stats_print() always reports at least most events that have occurred thus far.

Implement mallctl{nametomib,bymib}(). Replace chunk stats code that was missing locking; this fixes a race condition that could corrupt chunk statistics.
