- 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.
  * 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. (@djwatson)
    + Detect failed profile fetches. (@djwatson)
 * Fix stats.arenas.<i>.{dss,lg_dirty_mult,decay_time,pactive,pdirty} for --disable-stats case.

-------------------------------------------------------------------
Fri Jan 24 12:02:33 UTC 2014 - idonmez@suse.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 09:28:50 UTC 2013 - idonmez@suse.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  6 10:52:02 UTC 2013 - idonmez@suse.com

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

-------------------------------------------------------------------
Wed Jun  5 14:49:45 UTC 2013 - idonmez@suse.com

- Update to version 3.4.0
  * Support for aarch64
  * Fix race-triggered deadlocks in chunk_record()

-------------------------------------------------------------------
Thu Mar  7 20:50:35 UTC 2013 - idonmez@suse.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

-------------------------------------------------------------------
Thu Jan 24 11:56:49 UTC 2013 - idonmez@suse.com

  * Fix "arenas.extend" mallctl to output the number of arenas.
  * Fix chunk_recycyle() to unconditionally inform Valgrind that
    returned memory is undefined.
  * Fix build break on FreeBSD related to alloca.h.

-------------------------------------------------------------------

- Update to new upstream release 3.2.0
* Fix deadlock in the "arenas.purge" mallctl.
- Update to new upstream release 3.1.0
* Auto-detect whether running inside Valgrind, thus removing the
  need to manually specify MALLOC_CONF=valgrind:true.
* Disable tcache by default if running inside Valgrind, in order to
  avoid making unallocated objects appear reachable to Valgrind.
* Fix heap profiling crash if sampled object is freed via realloc(p, 0).

-------------------------------------------------------------------

  class without actually allocating.
* Implement aligned_alloc()
* Add the "thread.tcache.enabled" and "opt.prof_final" mallctls.
* Update pprof (from gperftools 2.0).
