Add the --enable-swap configure option. Add malloc_swap_enable(). Add the O/o JEMALLOC_OPTIONS flags, which control memory overcommit. Fix mapped memory stats reporting for arenas. 2010-01-24 18:53:40 +08:00			`/******************************************************************************/`

Fix mlockall()/madvise() interaction. mlockall(2) can cause purging via madvise(2) to fail. Fix purging code to check whether madvise() succeeded, and base zeroed page metadata on the result. Reported by Olivier Lecomte. 2012-10-09 08:56:11 +08:00			`bool pages_purge(void *addr, size_t length);`
Add a pages_purge function to wrap madvise(JEMALLOC_MADV_PURGE) calls This will be used to implement the feature on mingw, which doesn't have madvise. 2012-04-19 00:29:43 +08:00
Fix a memory corruption bug in chunk_alloc_dss(). Fix a memory corruption bug in chunk_alloc_dss() that was due to claiming newly allocated memory is zeroed. Reverse order of preference between mmap() and sbrk() to prefer mmap(). Clean up management of 'zero' parameter in chunk_alloc*(). 2012-04-22 04:33:48 +08:00			`void chunk_alloc_mmap(size_t size, size_t alignment, bool zero);`
Disable munmap() if it causes VM map holes. Add a configure test to determine whether common mmap()/munmap() patterns cause VM map holes, and only use munmap() to discard unused chunks if the problem does not exist. Unify the chunk caching for mmap and dss. Fix options processing to limit lg_chunk to be large enough that redzones will always fit. 2012-04-13 11:20:58 +08:00			`bool chunk_dealloc_mmap(void *chunk, size_t size);`
