Changelog for jemalloc-debugsource-4.1.0-34.1.x86_64.rpm :

* Mon Feb 29 2016 idonmezAATTsuse.com- Update to version 4.1.0 New features:
* Implement decay-based unused dirty page purging, a major optimization with mallctl API impact. This is an alternative to the existing ratio-based unused dirty page purging, and is intended to eventually become the sole purging mechanism. New mallctls: + opt.purge + opt.decay_time + arena..decay + arena..decay_time + arenas.decay_time + stats.arenas..decay_time
* Add --with-malloc-conf, which makes it possible to embed a default options string during configuration. This was motivated by the desire to specify - -with-malloc-conf=purge:decay , since the default must remain purge:ratio until the 5.0.0 release.
* Make
*allocx() size class overflow behavior defined. The maximum size class is now less thanPTRDIFF_MAX to protect applications against numerical overflow, and all allocation functions are guaranteed to indicate errors rather than potentially crashing if the request size exceeds the maximum size class.
* jeprof: + Add raw heap profile support. + Add --retain and --exclude for backtrace symbol filtering. Optimizations:
* Optimize the fast path to combine various bootstrapping and configuration checks and execute more streamlined code in the common case.
* Use linear scan for small bitmaps (used for small object tracking). In addition to speeding up bitmap operations on 64-bit systems, this reduces allocator metadata overhead by approximately 0.2%.
* Separate arena_avail trees, which substantially speeds up run tree operations.
* Use memoization (boot-time-computed table) for run quantization. Separate arena_avail trees reduced the importance of this optimization.
* Attempt mmap-based in-place huge reallocation. This can dramatically speed up incremental huge reallocation. Incompatible changes:
* Make opt.narenas unsigned rather than size_t. Bug fixes:
* Fix stats.cactive accounting regression.
* Handle unaligned keys in hash(). This caused problems for some ARM systems.
* Refactor arenas array. In addition to fixing a fork-related deadlock, this makes arena lookups faster and simpler.
* Move retained memory allocation out of the default chunk allocation function, to a location that gets executed even if the application installs a custom chunk allocation function. This resolves a virtual memory leak.
* Fix a potential tsd cleanup leak.
* Fix run quantization. In practice this bug had no impact unless applications requested memory with alignment exceeding one page.
* Fix LinuxThreads-specific bootstrapping deadlock. (Cosmin Paraschiv)
* jeprof: + Don\'t discard curl options if timeout is not defined. (AATTdjwatson) + Detect failed profile fetches. (AATTdjwatson)
* Fix stats.arenas..{dss,lg_dirty_mult,decay_time,pactive,pdirty} for --disable-stats case.
* Sun Feb 14 2016 olafAATTaepfle.de- Fix build/test in SLE_11 by using gcc48
* Sat Oct 24 2015 idonmezAATTsuse.com- Update to version 4.0.4
* Fix xallocx(..., MALLOCX_ZERO to zero the last full trailing page of large allocations that have been randomly assigned an offset of 0 when --enable-cache-oblivious configure option is enabled.
* Fri Sep 25 2015 idonmezAATTsuse.com- Update to version 4.0.3
* See included ChangeLog for complete changes.
* Mon Mar 31 2014 idonmezAATTsuse.com- Update to 3.6.0
* Fix a regression in arena_chunk_alloc() that caused crashes during small/large allocation if chunk allocation failed.
* Fix backtracing for gcc intrinsics-based backtracing by specifying - fno-omit-frame-pointer to gcc.
* Use dss allocation precedence for huge allocations as well as small/large allocations.
* Testsuite fixes- Drop jemalloc-fix-backtracing.patch, merged upstream.
* Mon Mar 31 2014 idonmezAATTsuse.com- Enable profiling- Add jemalloc-fix-backtracing.patch to fix profiling tests on x86 (the failures were triggered due to profiling support.)
* Wed Feb 26 2014 idonmezAATTsuse.com- Update to version 3.5.1
* Fix junk filling for mremap(2)-based huge reallocation.
* Unit test fixes- Remove jemalloc-fix-32bit-tests.patch, fixed upstream.
* Wed Jan 29 2014 idonmezAATTsuse.com- Add jemalloc-fix-32bit-tests.patch to fix test failures on i586
* Fri Jan 24 2014 idonmezAATTsuse.com- Update to version 3.5.0
* Add the
*allocx() API, which is a successor to the experimental
*allocm() API. The
*allocx() functions are slightly simpler to use because they have fewer parameters, they directly return the results of primary interest, and mallocx()/rallocx() avoid the strict aliasing pitfall that allocm()/rallocx() share with posix_memalign(). Note that
*allocm() is slated for removal in the next non-bugfix release.
* Add support for LinuxThreads.
* Unless heap profiling is enabled, disable floating point code and don\'t link with libm. This, in combination with e.g. EXTRA_CFLAGS=-mno-sse on x64 systems, makes it possible to completely disable floating point register use. Some versions of glibc neglect to save/restore caller-saved floating point registers during dynamic lazy symbol loading, and the symbol loading code uses whatever malloc the application happens to have linked/loaded with, the result being potential floating point register corruption.
* Report ENOMEM rather than EINVAL if an OOM occurs during heap profiling backtrace creation in imemalign(). This bug impacted posix_memalign() and aligned_alloc().
* Fix a file descriptor leak in a prof_dump_maps() error path.
* Fix prof_dump() to close the dump file descriptor for all relevant error paths.
* Fix rallocm() to use the arena specified by the ALLOCM_ARENA(s) flag for allocation, not just deallocation.
* Fix a data race for large allocation stats counters.
* Fix a potential infinite loop during thread exit. This bug occurred on Solaris, and could affect other platforms with similar pthreads TSD implementations.
* Don\'t junk-fill reallocations unless usable size changes. This fixes a violation of the
*allocx()/
*allocm() semantics.
* Fix growing large reallocation to junk fill new space.
* Fix huge deallocation to junk fill when munmap is disabled.
* Change the default private namespace prefix from empty to je_, and change - -with-private-namespace-prefix so that it prepends an additional prefix rather than replacing je_. This reduces the likelihood of applications which statically link jemalloc experiencing symbol name collisions.
* Add missing private namespace mangling (relevant when - -with-private-namespace is specified).
* Add and use JEMALLOC_INLINE_C so that static inline functions are marked as static even for debug builds.
* Add a missing mutex unlock in a malloc_init_hard() error path. In practice this error path is never executed.
* Fix numerous bugs in malloc_strotumax() error handling/reporting. These bugs had no impact except for malformed inputs.
* Fix numerous bugs in malloc_snprintf(). These bugs were not exercised by existing calls, so they had no impact.
* Tue Oct 22 2013 idonmezAATTsuse.com- Update to version 3.4.1
* Fix a race in the \"arenas.extend\" mallctl that could cause memory corruption of internal data structures and subsequent crashes.
* Fix Valgrind integration flaws that caused Valgrind warnings about reads of uninitialized memory in: + arena chunk headers + internal zero-initialized data structures
* Preserve errno during the first allocation. A readlink(2) call during initialization fails unless /etc/malloc.conf exists, so errno was typically set during the first allocation prior to this fix.
* Fix compilation warnings reported by gcc 4.8.1
* Thu Jun 06 2013 idonmezAATTsuse.com- Rename pprof to pprof-jemalloc to prevent conflict with gperftools
* Wed Jun 05 2013 idonmezAATTsuse.com- Update to version 3.4.0

* Thu Mar 07 2013 idonmezAATTsuse.com- Update to version 3.3.1
* Fix a locking order bug that could cause deadlock during fork if heap profiling were enabled.
* Fix a chunk recycling bug that could cause the allocator to lose track of whether a chunk was zeroed.
* Fix TLS-related memory corruption that could occur during thread exit if the thread never allocated memory. Only the quarantine and prof facilities were susceptible.
* Internal reallocation of the quarantined object array leaked the old array.
* Reallocation failure for internal reallocation of the quarantined object array (very unlikely) resulted in memory corruption.
* Fix Valgrind integration to annotate all internally allocated memory in a way that keeps Valgrind happy about internal data structure access.
* Fix building for s390 systems.- Implement %check
