* Add stats: arena uptime.Qi Wang2017-05-186-0/+42
|
* Avoid over-rebuilding due to namespace mangling.Jason Evans2017-05-172-3/+10
| | | | | | | Take care not to touch generated namespace mangling headers unless their contents would change. This resolves #838.
* Use srcroot path for private_namespace.sh.Qi Wang2017-05-161-2/+2
|
* Refactor (MALLOCX_ARENA_MAX + 1) to be MALLOCX_ARENA_LIMIT.Jason Evans2017-05-145-11/+11
| | | | This resolves #673.
* Automatically generate private symbol name mangling macros.Jason Evans2017-05-129-671/+239
| | | | | | | | Rather than using a manually maintained list of internal symbols to drive name mangling, add a compilation phase to automatically extract the list of internal symbols. This resolves #677.
* Remove unused private_unnamespace infrastructure.Jason Evans2017-05-123-15/+0
|
* Stop depending on JEMALLOC_N() for function interception during testing.Jason Evans2017-05-1213-281/+157
| | | | | | Instead, always define function pointers for interceptable functions, but mark them const unless testing, so that the compiler can optimize out the pointer dereferences.
* Do not build in parallel on AppVeyor.Jason Evans2017-05-121-2/+2
| | | | | | The compiler database used by MSVC is increasingly becoming corrupt, presumably due to concurrency-related corruption, despite the -FS compiler flag being specified as recommended.
* Update and rename INSTALL to INSTALL.mdArkady Shapkin2017-05-121-57/+107
|
* Specify -Werror for run_tests builds.Jason Evans2017-05-121-1/+1
|
* Avoid compiler warnings on Windows.Jason Evans2017-05-121-5/+5
|
* Remove mutex_prof_data_t redeclaration.Jason Evans2017-05-112-2/+1
| | | | | | | Redeclaration causes compilations failures with e.g. gcc 4.2.1 on FreeBSD. This regression was introduced by 89e2d3c12b573310e60b97beaf178007a71d83a3 (Header refactoring: ctl - unify and remove from catchall.).
* Add --with-version=VERSION .Jason Evans2017-05-032-6/+21
| | | | | | | This simplifies configuration when embedding a jemalloc release into another project's git repository. This resolves #811.
* Fix rtree_leaf_elm_szind_slab_update().Jason Evans2017-05-031-8/+7
| | | | | | | | | | | Re-read the leaf element when atomic CAS fails due to a race with another thread that has locked the leaf element, since atomic_compare_exchange_strong_p() overwrites the expected value with the actual value on failure. This regression was introduced by 0ee0e0c155a05d0d028a9972ad86b9eaac4ccabd (Implement compact rtree leaf element representation.). This resolves #798.
* rtree_leaf_elm_extent_write() --> rtree_leaf_elm_extent_lock_write()Jason Evans2017-05-031-8/+9
| | | | | | | Refactor rtree_leaf_elm_extent_write() as rtree_leaf_elm_extent_lock_write(), so that whether the leaf element is currently acquired is separate from what lock state to write. This allows for a relaxed atomic read when releasing the lock.
* Make VS2015 project work againrustyx2017-05-022-238/+9

* Revert "Use trylock in tcache_bin_flush when possible."Qi Wang2017-05-013-142/+63
| | | | | This reverts commit 8584adc451f31adfc4ab8693d9189cf3a7e5d858. Production results not favorable. Will investigate separately.
* Header refactoring: tsd - cleanup and dependency breaking.David Goldblatt2017-05-0129-913/+870
| | | | | | | | | | | | This removes the tsd macros (which are used only for tsd_t in real builds). We break up the circular dependencies involving tsd. We also move all tsd access through getters and setters. This allows us to assert that we only touch data when tsd is in a valid state. We simplify the usages of the x macro trick, removing all the customizability (get/set, init, cleanup), moving the lifetime logic to tsd_init and tsd_cleanup. This lets us make initialization order independent of order within tsd_t.
* Add extent_destroy_t and use it during arena destruction.Jason Evans2017-04-2910-17/+120
| | | | | | | | | | Add the extent_destroy_t extent destruction hook to extent_hooks_t, and use it during arena destruction. This hook explicitly communicates to the callee that the extent must be destroyed or tracked for later reuse, lest it be permanently leaked. Prior to this change, retained extents could unintentionally be leaked if extent retention was enabled. This resolves #560.
* Refactor !opt.munmap to opt.retain.Jason Evans2017-04-2916-43/+42
|
* Revert "Use try_flush first in tcache_dalloc."Qi Wang2017-04-281-10/+4
| | | | | | This reverts commit b0c2a28280d363fc85aa8b4fdbe7814ef46cb17b. Production benchmark shows this caused significant regression in both CPU and memory consumption. Will investigate separately later on.
* Inline tcache_bin_flush_small_impl / _large_impl.Qi Wang2017-04-281-2/+2
|
* Use try_flush first in tcache_dalloc.Qi Wang2017-04-261-4/+10
| | | | Only do must_flush if try_flush didn't manage to free anything.
* Use trylock in tcache_bin_flush when possible.Qi Wang2017-04-263-63/+142
| | | | | During tcache gc, use tcache_bin_try_flush_small / _large so that we can skip items with their bins locked already.
* Remove redundant extent lookup in tcache_bin_flush_large.Qi Wang2017-04-251-1/+1
|
* Avoid prof_dump during reentrancy.Qi Wang2017-04-252-12/+23
|
* Header refactoring: pages.h - unify and remove from catchall.David Goldblatt2017-04-256-34/+33
|
* Header refactoring: hash - unify and remove from catchall.David Goldblatt2017-04-255-4/+6
|
* Header refactoring: ctl - unify and remove from catchall.David Goldblatt2017-04-2511-264/+257
| | | | | In order to do this, we introduce the mutex_prof module, which breaks a circular dependency between ctl and prof.
* Replace --disable-munmap with opt.munmap.Jason Evans2017-04-2516-85/+77
| | | | | | | | | 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.
* Remove --enable-code-coverage.Jason Evans2017-04-246-109/+1
| | | | | | | This option hasn't been particularly useful since the original pre-3.0.0 push to broaden test coverage. This partially resolves #580.
* Remove --disable-cc-silence.Jason Evans2017-04-245-41/+6
| | | | | | | The explicit compiler warning suppression controlled by this option is universally desirable, so remove the ability to disable suppression. This partially resolves #580.
* Use trylock in arena_decay_impl().Qi Wang2017-04-241-8/+16
| | | | If another thread is working on decay, we don't have to wait for the mutex.
* Implement malloc_mutex_trylock() w/ proper stats update.Qi Wang2017-04-243-14/+36
|
* Remove --with-lg-tiny-min.Jason Evans2017-04-244-41/+11
| | | | | | This option isn't useful in practice. This partially resolves #580.
* Remove --with-lg-size-class-group.Jason Evans2017-04-242-39/+2
| | | | | | | | Four size classes per size doubling has proven to be a universally good choice for the entire 4.x release series, so there's little point to preserving this configurability. This partially resolves #580.

* Get rid of most of the various inline macros.David Goldblatt2017-04-2431-669/+233
|
* Add missing 'test' to LG_SIZEOF_PTR tests.Jason Evans2017-04-241-3/+3
| | | | | | This fixes a bug/regression introduced by a01f99307719dcc8ca27cc70f0f0011beff914fa (Only disable munmap(2) by default on 64-bit Linux.).
* Output MALLOC_CONF and debug cmd when test failure happens.Qi Wang2017-04-221-9/+10
|
* Enable -Wundef, when supported.David Goldblatt2017-04-225-13/+12
| | | | | | This can catch bugs in which one header defines a numeric constant, and another uses it without including the defining header. Undefined preprocessor symbols expand to '0', so that this will compile fine, silently doing the math wrong.
* Remove --enable-ivsalloc.Jason Evans2017-04-215-42/+23
| | | | | | | | | | | | Continue to use ivsalloc() when --enable-debug is specified (and add assertions to guard against 0 size), but stop providing a documented explicit semantics-changing band-aid to dodge undefined behavior in sallocx() and malloc_usable_size(). ivsalloc() remains compiled in, unlike when #211 restored --enable-ivsalloc, and if JEMALLOC_FORCE_IVSALLOC is defined during compilation, sallocx() and malloc_usable_size() will still use ivsalloc(). This partially resolves #580.
* Remove --disable-tls.Jason Evans2017-04-216-43/+4
| | | | | | | This option is no longer useful, because TLS is correctly configured automatically on all supported platforms. This partially resolves #580.
* Use openat syscall if availableJim Chen2017-04-212-0/+8
| | | | | | | | | | Some architectures like AArch64 may not have the open syscall because it was superseded by the openat syscall, so check and use SYS_openat if SYS_open is not available. Additionally, Android headers for AArch64 define SYS_open to __NR_open, even though __NR_open is undefined. Undefine SYS_open in that case so SYS_openat is used.
