- 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.<i>.decay + arena.<i>.decay_time + arenas.decay_time + stats.arenas.<i>.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.

- 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. - Enable profiling - Add jemalloc-fix-backtracing.patch to fix profiling tests on x86 (the failures were triggered due to profiling support.)

- Add jemalloc-fix-32bit-tests.patch to fix test failures on i586 - 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

- 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 - Rename pprof to pprof-jemalloc to prevent conflict with gperftools

- 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
