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.
2009-06-26 09:06:48 +08:00
#ifdef __cplusplus
extern "C" {
#endif
Fix compiler warnings and errors. Use INT_MAX instead of MAX_INT in ALLOCM_ALIGN(), and #include <limits.h> in order to get its definition. Modify prof code related to hash tables to avoid aliasing warnings from gcc 4.1.2 (gcc 4.4.0 and 4.4.3 do not warn).
2010-09-21 10:53:25 +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.

Add --with-mangling. Add the --with-mangling configure option, which can be used to specify name mangling on a per public symbol basis that takes precedence over --with-jemalloc-prefix. Expose the memalign() and valloc() overrides even if --with-jemalloc-prefix is specified. This change does no real harm, and simplifies the code.

extern const char *je_malloc_conf;
extern void (*je_malloc_message)(void *, const char *);
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.

int je_posix_memalign(void **memptr, size_t alignment, size_t size)
Simplify JEMALLOC_ATTR_* macros to become JEMALLOC_ATTR(). Use JEMALLOC_ATTR(tls_model("initial-exec)) instead of -ftls-model=initial-exec so that libjemalloc_pic.a can be directly linked into another library without needing linker options changes. Add attributes to malloc, calloc, and posix_memalign, for compatibility with glibc's declarations. Add function prototypes for the standard malloc(3) API.
2010-01-04 03:59:20 +08:00
JEMALLOC_ATTR(nonnull(1));
Implement aligned_alloc(). Implement aligned_alloc(), which was added in the C11 standard. The function is weakly specified to the point that a minimally compliant implementation would be painful to use (size must be an integral multiple of alignment!), which in practice makes posix_memalign() a safer choice.
