Generalize chunk management hooks. Add the "arena.<i>.chunk_hooks" mallctl, which replaces and expands on the "arena.<i>.chunk.{alloc,dalloc,purge}" mallctls. The chunk hooks allow control over chunk allocation/deallocation, decommit/commit, purging, and splitting/merging, such that the application can rely on jemalloc's internal chunk caching and retaining functionality, yet implement a variety of chunk management mechanisms and policies. Merge the chunks_[sz]ad_{mmap,dss} red-black trees into chunks_[sz]ad_retained. This slightly reduces how hard jemalloc tries to honor the dss precedence setting; prior to this change the precedence setting was also consulted when recycling chunks. Fix chunk purging. Don't purge chunks in arena_purge_stashed(); instead deallocate them in arena_unstash_purged(), so that the dirty memory linkage remains valid until after the last time it is used. This resolves #176 and #201. 2015-07-28 23:28:19 +08:00			`/******************************************************************************/`

Modify pages_map() to support mapping uncommitted virtual memory. If the OS overcommits: - Commit all mappings in pages_map() regardless of whether the caller requested committed memory. - Linux-specific: Specify MAP_NORESERVE to avoid unfortunate interactions with heuristic overcommit mode during fork(2). This resolves #193. 2016-05-06 08:45:02 +08:00			`void pages_map(void addr, size_t size, bool *commit);`
