* 2.2.0 (March 22, 2011)
|
||||||
|
|
||||||
|
This version incorporates several improvements to algorithms and data
|
||||||
|
structures that tend to reduce fragmentation and increase speed.
|
||||||
|
|
||||||
|
New features:
|
||||||
|
- Add the "stats.cactive" mallctl.
|
||||||
|
- Update pprof (from google-perftools 1.7).
|
||||||
|
- Improve backtracing-related configuration logic, and add the
|
||||||
|
--disable-prof-libgcc option.
|
||||||
|
|
||||||
|
Bug fixes:
|
||||||
|
- Change default symbol visibility from "internal", to "hidden", which
|
||||||
|
decreases the overhead of library-internal function calls.
|
||||||
|
- Fix symbol visibility so that it is also set on OS X.
|
||||||
|
- Fix a build dependency regression caused by the introduction of the .pic.o
|
||||||
|
suffix for PIC object files.
|
||||||
|
- Add missing checks for mutex initialization failures.
|
||||||
|
- Don't use libgcc-based backtracing except on x64, where it is known to work.
|
||||||
|
- Fix deadlocks on OS X that were due to memory allocation in
|
||||||
|
pthread_mutex_lock().
|
||||||
|
- Heap profiling-specific fixes:
|
||||||
|
+ Fix memory corruption due to integer overflow in small region index
|
||||||
|
computation, when using a small enough sample interval that profiling
|
||||||
|
context pointers are stored in small run headers.
|
||||||
|
+ Fix a bootstrap ordering bug that only occurred with TLS disabled.
|
||||||
|
+ Fix a rallocm() rsize bug.
|
||||||
|
+ Fix error detection bugs for aligned memory allocation.
