* 3.1.0 (October 16, 2012)
|
||||
|
||||
New features:
|
||||
- Auto-detect whether running inside Valgrind, thus removing the need to
|
||||
manually specify MALLOC_CONF=valgrind:true.
|
||||
- Add the "arenas.extend" mallctl, which allows applications to create
|
||||
manually managed arenas.
|
||||
- Add the ALLOCM_ARENA() flag for {,r,d}allocm().
|
||||
- Add the "opt.dss", "arena.<i>.dss", and "stats.arenas.<i>.dss" mallctls,
|
||||
which provide control over dss/mmap precedence.
|
||||
- Add the "arena.<i>.purge" mallctl, which obsoletes "arenas.purge".
|
||||
- Define LG_QUANTUM for hppa.
|
||||
|
||||
Incompatible changes:
|
||||
- Disable tcache by default if running inside Valgrind, in order to avoid
|
||||
making unallocated objects appear reachable to Valgrind.
|
||||
- Drop const from malloc_usable_size() argument on Linux.
|
||||
|
||||
Bug fixes:
|
||||
- Fix heap profiling crash if sampled object is freed via realloc(p, 0).
|
||||
- Remove const from __*_hook variable declarations, so that glibc can modify
|
||||
them during process forking.
|
||||
- Fix mlockall(2)/madvise(2) interaction.
|
||||
- Fix fork(2)-related deadlocks.
|
||||
- Fix error return value for "thread.tcache.enabled" mallctl.
