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. 2017-01-11 10:06:31 +08:00			`#ifndef JEMALLOC_INTERNAL_EXTENT_STRUCTS_H`

Header refactoring: move atomic.h out of the catch-all 2017-04-11 10:04:40 +08:00			`#include "jemalloc/internal/atomic.h"`
Header refactoring: bitmap - unify and remove from catchall. 2017-04-21 05:32:24 +08:00			`#include "jemalloc/internal/bitmap.h"`
Header refactoring: unify and de-catchall mutex module 2017-05-24 03:28:19 +08:00			`#include "jemalloc/internal/mutex.h"`
Header refactoring: break out ql.h dependencies 2017-04-11 08:11:33 +08:00			`#include "jemalloc/internal/ql.h"`
Prefer old/low extent_t structures during reuse. Rather than using a LIFO queue to track available extent_t structures, use a red-black tree, and always choose the oldest/lowest available during reuse. 2017-04-17 13:31:16 +08:00			`#include "jemalloc/internal/ph.h"`
Hide size class computation behind a layer of indirection. This class removes almost all the dependencies on size_classes.h, accessing the data there only via the new module sc.h, which does not depend on any configuration options. In a subsequent commit, we'll remove the configure-time size class computations, doing them at boot time, instead. 2017-12-15 04:46:39 +08:00			`#include "jemalloc/internal/sc.h"`
Rearrange slab data and constants The constants logically belong in the sc module. The slab data bitmap isn't really scoped to an arena; move it to its own module. 2019-09-21 07:36:42 +08:00			`#include "jemalloc/internal/slab_data.h"`
Header refactoring: break out ph.h dependencies 2017-04-11 07:54:25 +08:00
Add memory utilization analytics to mallctl The analytics tool is put under experimental.utilization namespace in mallctl. Input is one pointer or an array of pointers and the output is a list of memory utilization statistics. 2019-03-16 02:01:45 +08:00			`/*`
