| 37 38 Incompatible changes: 39 - Enable stats by default. 40 - Enable fill by default. 41 - Disable lazy locking by default. 42 - Rename the "tcache.flush" mallctl to "thread.tcache.flush". 43 - Rename the "arenas.pagesize" mallctl to "arenas.page". | 39 40 Incompatible changes: 41 - Enable stats by default. 42 - Enable fill by default. 43 - Disable lazy locking by default. 44 - Rename the "tcache.flush" mallctl to "thread.tcache.flush". 45 - Rename the "arenas.pagesize" mallctl to "arenas.page". |
| 46 - Change the "opt.lg_prof_sample" default from 0 to 19 (1 B to 512 KiB). 47 - Change the "opt.prof_accum" default from true to false. |

| 44 45 Removed features: 46 - Remove the swap feature, including the "config.swap", "swap.avail", 47 "swap.prezeroed", "swap.nfds", and "swap.fds" mallctls. 48 - Remove highruns statistics, including the 49 "stats.arenas.<i>.bins.<j>.highruns" and 50 "stats.arenas.<i>.lruns.<j>.highruns" mallctls. 51 - As part of small size class refactoring, remove the "opt.lg_[qc]space_max", --- 20 unchanged lines hidden (view full) --- 72 - Check for NULL pointer in malloc_usable_size(). 73 - Fix bin->runcur management to fix a layout policy bug. This bug did not 74 affect correctness. 75 - Fix a bug in choose_arena_hard() that potentially caused more arenas to be 76 initialized than necessary. 77 - Add missing "opt.lg_tcache_max" mallctl implementation. 78 - Use glibc allocator hooks to make mixed allocator usage less likely. 79 - Fix build issues for --disable-tcache. | 48 49 Removed features: 50 - Remove the swap feature, including the "config.swap", "swap.avail", 51 "swap.prezeroed", "swap.nfds", and "swap.fds" mallctls. 52 - Remove highruns statistics, including the 53 "stats.arenas.<i>.bins.<j>.highruns" and 54 "stats.arenas.<i>.lruns.<j>.highruns" mallctls. 55 - As part of small size class refactoring, remove the "opt.lg_[qc]space_max", --- 20 unchanged lines hidden (view full) --- 76 - Check for NULL pointer in malloc_usable_size(). 77 - Fix bin->runcur management to fix a layout policy bug.

| 80 81* 2.2.5 (November 14, 2011) 82 83 Bug fixes: 84 - Fix huge_ralloc() race when using mremap(2).
