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			`#ifdef JEMALLOC_SWAP`

Implement mallctl{nametomib,bymib}(). Replace chunk stats code that was missing locking; this fixes a race condition that could corrupt chunk statistics. Converting malloc_stats_print() to use mallctl*(). Add a missing semicolon in th DSS code. Convert malloc_tcache_flush() to a mallctl. Convert malloc_swap_enable() to a set of mallctl's. 2010-01-28 05:10:55 +08:00			`extern bool swap_prezeroed;`

Modify chunk_alloc() to support optional zeroing. Use optional zeroing in arena_chunk_alloc() to avoid needless zeroing of chunks. This is particularly important in the context of swapfile and DSS allocation, since a long-lived application may commonly recycle chunks. 2010-01-25 09:13:07 +08:00			`void chunk_alloc_swap(size_t size, bool zero);`
Use mremap(2) for huge realloc(). If mremap(2) is available and supports MREMAP_FIXED, use it for huge realloc(). Initialize rtree later during bootstrapping, so that --enable-debug --enable-dss works. Fix a minor swap_avail stats bug. 2010-12-01 08:50:58 +08:00			`bool chunk_in_swap(void *chunk);`
