* 3.0.0 (XXX not yet released)
|
||||||
|
|
||||||
|
Although this version adds some major new features, the primary focus is on
|
||||||
|
internal code cleanup that facilitates maintainability and portability, most
|
||||||
|
of which is not reflected in the ChangeLog. This is the first release to
|
||||||
|
incorporate substantial contributions from numerous other developers, and the
|
||||||
|
result is a more broadly useful allocator (see the git revision history for
|
||||||
|
contribution details). Note that the license has been unified, thanks to
|
||||||
|
Facebook granting a license under the same terms as the other copyright
|
||||||
|
holders (see COPYING).
|
||||||
|
|
||||||
|
New features:
|
||||||
|
- Implement Valgrind support, redzones, and quarantine.
|
||||||
|
- Add support for additional operating systems:
|
||||||
|
+ FreeBSD
|
||||||
|
+ Mac OS X Lion
|
||||||
|
- Add support for additional architectures:
|
||||||
|
+ MIPS
|
||||||
|
+ SH4
|
||||||
|
+ Tilera
|
||||||
|
- Add support for cross compiling.
|
||||||
|
- Add nallocm(), which rounds a request size up to the nearest size class
|
||||||
|
without actually allocating.
|
||||||
|
- Implement aligned_alloc() (blame C11).
|
||||||
|
- Add the --disable-munmap option, and make it the default on Linux.
|
||||||
|
- Add the --with-mangling option.
|
||||||
|
- Add the --disable-experimental option.
|
||||||
|
- Add the "thread.tcache.enabled" mallctl.
|
||||||
|
|
||||||
|
Incompatible changes:
|
||||||
|
- Enable stats by default.
|
||||||
|
- Enable fill by default.
|
||||||
|
- Disable lazy locking by default.
|
||||||
|
- Rename the "tcache.flush" mallctl to "thread.tcache.flush".
|
||||||
|
- Rename the "arenas.pagesize" mallctl to "arenas.page".
|
||||||
|
|
||||||
|
Removed features:
|
||||||
|
- Remove the swap feature, including the "config.swap", "swap.avail",
|
||||||
|
"swap.prezeroed", "swap.nfds", and "swap.fds" mallctls.
|
||||||
|
- Remove highruns statistics, including the
|
||||||
|
"stats.arenas.<i>.bins.<j>.highruns" and
|
||||||
|
"stats.arenas.<i>.lruns.<j>.highruns" mallctls.
|
||||||
|
- As part of small size class refactoring, remove the "opt.lg_[qc]space_max",
|
||||||
|
"arenas.cacheline", "arenas.subpage", "arenas.[tqcs]space_{min,max}", and
|
||||||
|
"arenas.[tqcs]bins" mallctls.
|
||||||
|
- Remove the "arenas.chunksize" mallctl.
|
||||||
|
- Remove the "opt.lg_prof_tcmax" option.
|
||||||
|
- Remove the "opt.lg_prof_bt_max" option.
|
||||||
|
- Remove the "opt.lg_tcache_gc_sweep" option.
|
||||||
|
- Remove the --disable-tiny option, including the "config.tiny" mallctl.
|
||||||
|
- Remove the --enable-dynamic-page-shift configure option.
|
||||||
|
- Remove the --enable-sysv configure option.
|
||||||
|
|
||||||
|
Bug fixes:
|
||||||
|
- Fix fork-related bugs that could cause deadlock in children between fork
|
||||||
|
and exec.
|
||||||
|
- Fix a statistics-related bug in the "thread.arena" mallctl that could cause
|
||||||
|
invalid statistics and crashes.
|
||||||
|
- Work around TLS dallocation via free() on Linux. This bug could cause
|
||||||
|
write-after-free memory corruption.
|
||||||
|
- Fix malloc_stats_print() to honor 'b' and 'l' in the opts parameter.
|
||||||
|
- Fix realloc(p, 0) to act like free(p).
|
||||||
|
- Do not enforce minimum alignment in memalign().
|
||||||
|
- Check for NULL pointer in malloc_usable_size().
|
||||||
|
- Fix bin->runcur management to fix a layout policy bug. This bug did not
|
||||||
|
affect correctness.
|
||||||
|
- Fix a bug in choose_arena_hard() that potentially caused more arenas to be
|
||||||
|
initialized than necessary.
|
||||||
|
- Add missing "opt.lg_tcache_max" mallctl implementation.
|
||||||
|
- Use glibc allocator hooks to make mixed allocator usage less likely.
|
||||||
|
- Fix build issues for --disable-tcache.
