Add configure options. Add: --with-lg-page --with-lg-page-sizes --with-lg-size-class-group --with-lg-quantum Get rid of STATIC_PAGE_SHIFT, in favor of directly setting LG_PAGE. Fix various edge conditions exposed by the configure options.

void *huge_malloc(tsd_t *tsd, arena_t *arena, size_t size, bool zero,
Implement explicit tcache support. Add the MALLOCX_TCACHE() and MALLOCX_TCACHE_NONE macros, which can be used in conjunction with the *allocx() API. Add the tcache.create, tcache.flush, and tcache.destroy mallctls. This resolves #145.

tcache_t *tcache);
Fix huge_palloc() to handle size rather than usize input. huge_ralloc() passes a size that may not be precisely a size class, so make huge_palloc() handle the more general case of a size input rather than usize. This regression appears to have been introduced by the addition of in-place huge reallocation; as such it was never incorporated into a release.

bool zero, tcache_t *tcache);
Implement decay-based unused dirty page purging. This is an alternative to the existing ratio-based unused dirty page purging, and is intended to eventually become the sole purging mechanism. Add mallctls: - opt.purge - opt.decay_time - arena.<i>.decay - arena.<i>.decay_time - arenas.decay_time - stats.arenas.<i>.decay_time This resolves #325.

Convert all tsd variables to reside in a single tsd structure.

void *huge_ralloc(tsd_t *tsd, arena_t *arena, void *ptr, size_t oldsize,
Fix xallocx() bugs. Fix xallocx() bugs related to the 'extra' parameter when specified as non-zero.

size_t usize, size_t alignment, bool zero, tcache_t *tcache);
Add junk/zero filling unit tests, and fix discovered bugs. Fix growing large reallocation to junk fill new space. Fix huge deallocation to junk fill when munmap is disabled.

void huge_dalloc(tsd_t *tsd, void *ptr, tcache_t *tcache);
Implement metadata statistics. There are three categories of metadata: - Base allocations are used for bootstrap-sensitive internal allocator data structures. - Arena chunk headers comprise pages which track the states of the non-metadata pages. - Internal allocations differ from application-originated allocations in that they are for internal use, and that they are omitted from heap profiles. The metadata statistics comprise the metadata categories as follows: - stats.metadata: All metadata -- base + arena chunk headers + internal allocations. - stats.arenas.<i>.metadata.mapped: Arena chunk headers. - stats.arenas.<i>.metadata.allocated: Internal allocations. This is reported separately from the other metadata statistics because it overlaps with the allocated and active statistics, whereas the other metadata statistics do not. Base allocations are not reported separately, though their magnitude can be computed by subtracting the arena-specific metadata. This resolves #163.

arena_t *huge_aalloc(const void *ptr);
Refactor jemalloc.c into multiple source files. Fix a stats bug in large object curruns accounting. Replace tcache_bin_fill() with arena_tcache_fill(), and fix a bug in an OOM error path. Fix API name mangling to coexist with __attribute__((malloc)).

size_t huge_salloc(const void *ptr);
Implement per thread heap profiling. Rename data structures (prof_thr_cnt_t-->prof_tctx_t, prof_ctx_t-->prof_gctx_t), and convert to storing a prof_tctx_t for sampled objects. Convert PROF_ALLOC_PREP() to prof_alloc_prep(), since precise backtrace depth within jemalloc functions is no longer an issue (pprof prunes irrelevant frames). Implement mallctl's: - prof.reset implements full sample data reset, and optional change of sample interval. - prof.lg_sample reads the current sample interval (opt.lg_prof_sample was the permanent source of truth prior to prof.reset). - thread.prof.name provides naming capability for threads within heap profile dumps. - thread.prof.active makes it possible to activate/deactivate heap profiling for individual threads. Modify the heap dump files to contain per thread heap profile data. This change is incompatible with the existing pprof, which will require enhancements to read and process the enriched data.

prof_tctx_t *huge_prof_tctx_get(const void *ptr);
void huge_prof_tctx_set(const void *ptr, prof_tctx_t *tctx);
Resolve an unsupported special case in arena_prof_tctx_set(). Add arena_prof_tctx_reset() and use it instead of arena_prof_tctx_set() when resetting the tctx pointer during reallocation, which happens whenever an originally sampled reallocated object is not sampled during reallocation. This regression was introduced by 594c759f37c301d0245dc2accf4d4aaf9d202819 (Optimize arena_prof_tctx_set().)
