Break up headers into constituent parts This is part of a broader change to make header files better represent the dependencies between one another (see https://github.com/jemalloc/jemalloc/issues/533). It breaks up component headers into smaller parts that can be made to have a simpler dependency graph. For the autogenerated headers (smoothstep.h and size_classes.h), no splitting was necessary, so I didn't add support to emit multiple headers.

Implementing opt.background_thread. Added opt.background_thread to enable background threads, which handles purging currently. When enabled, decay ticks will not trigger purging (which will be left to the background threads). We limit the max number of threads to NCPUs. When percpu arena is enabled, set CPU affinity for the background threads as well. The sleep interval of background threads is dynamic and determined by computing number of pages to purge in the future (based on backlog).

Refactor/fix background_thread/percpu_arena bootstrapping. Refactor bootstrapping such that dlsym() is called during the bootstrapping phase that can tolerate reentrant allocation.

extern percpu_arena_mode_t opt_percpu_arena;
extern const char *percpu_arena_mode_names[];
Implement per-CPU arena. The new feature, opt.percpu_arena, determines thread-arena association dynamically based CPU id. Three modes are supported: "percpu", "phycpu" and disabled. "percpu" uses the current core id (with help from sched_getcpu()) directly as the arena index, while "phycpu" will assign threads on the same physical CPU to the same arena. In other words, "percpu" means # of arenas == # of CPUs, while "phycpu" has # of arenas == 1/2 * (# of CPUs). Note that no runtime check on whether hyper threading is enabled is added yet. When enabled, threads will be migrated between arenas when a CPU change is detected. In the current design, to reduce overhead from reading CPU id, each arena tracks the thread accessed most recently. When a new thread comes in, we will read CPU id and update arena if necessary.

Drop high rank locks when creating threads. Avoid holding arenas_lock and background_thread_lock when creating background threads, because pthread_create may take internal locks, and potentially cause deadlock with jemalloc internal locks.

Implement huge arena: opt.huge_threshold. The feature allows using a dedicated arena for huge allocations. We want the addtional arena to separate huge allocation because: 1) mixing small extents with huge ones causes fragmentation over the long run (this feature reduces VM size significantly); 2) with many arenas, huge extents rarely get reused across threads; and 3) huge allocations happen way less frequently, therefore no concerns for lock contention.

const char **dss, ssize_t *dirty_decay_ms, ssize_t *muzzy_decay_ms,
Implement two-phase decay-based purging. Split decay-based purging into two phases, the first of which uses lazy purging to convert dirty pages to "muzzy", and the second of which uses forced purging, decommit, or unmapping to convert pages to clean or destroy them altogether. Not all operating systems support lazy purging, yet the application may provide extent hooks that implement lazy purging, so care must be taken to dynamically omit the first phase when necessary. The mallctl interfaces change as follows: - opt.decay_time --> opt.{dirty,muzzy}_decay_time - arena.<i>.decay_time --> arena.<i>.{dirty,muzzy}_decay_time - arenas.decay_time --> arenas.{dirty,muzzy}_decay_time - stats.arenas.<i>.pdirty --> stats.arenas.<i>.p{dirty,muzzy} - stats.arenas.<i>.{npurge,nmadvise,purged} --> stats.arenas.<i>.{dirty,muzzy}_{npurge,nmadvise,purged} This resolves #521.

Add extent_grow_mtx in pre_ / post_fork handlers. This fixed the issue that could cause the child process to stuck after fork.

Implementing opt.background_thread. Added opt.background_thread to enable background threads, which handles purging currently. When enabled, decay ticks will not trigger purging (which will be left to the background threads). We limit the max number of threads to NCPUs. When percpu arena is enabled, set CPU affinity for the background threads as well. The sleep interval of background threads is dynamic and determined by computing number of pages to purge in the future (based on backlog).

Break up headers into constituent parts This is part of a broader change to make header files better represent the dependencies between one another (see https://github.com/jemalloc/jemalloc/issues/533). It breaks up component headers into smaller parts that can be made to have a simpler dependency graph. For the autogenerated headers (smoothstep.h and size_classes.h), no splitting was necessary, so I didn't add support to emit multiple headers.
