* Header refactoring: unify and de-catchall extent_mmap module.David Goldblatt2017-05-311-0/+1

* Refactor !opt.munmap to opt.retain.Jason Evans2017-04-291-4/+4

* Replace --disable-munmap with opt.munmap.Jason Evans2017-04-241-2/+13
| | | | | | | | | Control use of munmap(2) via a run-time option rather than a compile-time option (with the same per platform default). The old behavior of --disable-munmap can be achieved with --with-malloc-conf=munmap:false. This partially resolves #580.
* Trim before commit in extent_recycle().Jason Evans2017-04-191-1/+3
| | | | | | | | | | This avoids creating clean committed pages as a side effect of aligned allocation. For configurations that decommit memory, purged pages are decommitted, and decommitted extents cannot be coalesced with committed extents. Unless the clean committed pages happen to be selected during allocation, they cause unnecessary permanent extent fragmentation. This resolves #766.
* Support --with-lg-page values larger than system page size.Jason Evans2017-04-181-56/+4
| | | | | | | | | All mappings continue to be PAGE-aligned, even if the system page size is smaller. This change is primarily intended to provide a mechanism for supporting multiple page sizes with the same binary; smaller page sizes work better in conjunction with jemalloc's design. This resolves #467.
* Header refactoring: move assert.h out of the catch-allDavid Goldblatt2017-04-181-0/+2

* Header refactoring: Split up jemalloc_internal.hDavid Goldblatt2017-04-111-1/+2
| | | | | | | | | | | | | | This is a biggy. jemalloc_internal.h has been doing multiple jobs for a while now: - The source of system-wide definitions. - The catch-all include file. - The module header file for jemalloc.c This commit splits up this functionality. The system-wide definitions responsibility has moved to jemalloc_preamble.h. The catch-all include file is now jemalloc_internal_includes.h. The module headers for jemalloc.c are now in jemalloc_internal_[externs|inlines|types].h, just as they are for the other modules.
* Replace tabs following #define with spaces.Jason Evans2017-01-201-1/+1
| | | | This resolves #564.
* Remove extraneous parens around return arguments.Jason Evans2017-01-201-7/+7
| | | | This resolves #540.
* Update brace style.Jason Evans2017-01-201-10/+12
| | | | | | | Add braces around single-line blocks, and remove line breaks before function-opening braces. This resolves #537.
* Remove leading blank lines from function bodies.Jason Evans2017-01-131-1/+0
| | | | This resolves #535.
* Fix potential VM map fragmentation regression.Jason Evans2016-06-071-1/+1
| | | | | | | | Revert 245ae6036c09cc11a72fab4335495d95cddd5beb (Support --with-lg-page values larger than actual page size.), because it could cause VM map fragmentation if the kernel grows mmap()ed memory downward. This resolves #391.
* Rename most remaining *chunk* APIs to *extent*.Jason Evans2016-06-051-0/+76
