Changelog for arangodb-jemalloc-devel-4.2.1-11.2.x86_64.rpm :
Fri May 13 14:00:00 2016 idonmezAATTsuse.com
- Update to version 4.2.0

* Add the arena..reset mallctl, which makes it possible to
discard all of an arena\'s allocations in a single operation.

* Add the stats.retained and stats.arenas..retained statistics.

* Add the --with-version configure option.

* Support --with-lg-page values larger than actual page size.

* Use pairing heaps rather than red-black trees for various hot
data structures.

* Streamline fast paths of rtree operations.

* Optimize the fast paths of calloc() and [m,d,sd]allocx().

* Decommit unused virtual memory if the OS does not overcommit.

* Specify MAP_NORESERVE on Linux if [heuristic] overcommit is active,
in order to avoid unfortunate interactions during fork(2).

* Fix chunk accounting related to triggering gdump profiles.

* Link against librt for clock_gettime(2) if glibc < 2.17.

* Scale leak report summary according to sampling probability.

Wed May 4 14:00:00 2016 idonmezAATTsuse.com
- Update to version 4.1.1

* Fix hashing functions to avoid unaligned memory accesses
(and resulting crashes). This is relevant at least to some
ARM-based platforms.

* Fix fork()-related lock rank ordering reversals. These reversals
were unlikely to cause deadlocks in practice except when heap
profiling was enabled and active.

* Fix various chunk leaks in OOM code paths.

* Fix malloc_stats_print() to print opt.narenas correctly.

* Fix a variety of test failures that were due to test fragility
rather than core bugs.
- Remove disable_oom_test.patch, fixed upstream.
- Run testsuite in parallel where possible

- add disable_oom_test.patch

Mon Feb 29 13:00:00 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.

of large allocations that have been randomly assigned an offset of
0 when --enable-cache-oblivious configure option is enabled.

Fri Sep 25 14:00:00 2015 idonmezAATTsuse.com

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 14:00:00 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 13:00:00 2014 idonmezAATTsuse.com
- Update to version 3.5.1

* Fix junk filling for mremap(2)-based huge reallocation.

Wed Jan 29 13:00:00 2014 idonmezAATTsuse.com
- Add jemalloc-fix-32bit-tests.patch to fix test failures on i586

Fri Jan 24 13:00:00 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 14:00:00 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 6 14:00:00 2013 idonmezAATTsuse.com
- Rename pprof to pprof-jemalloc to prevent conflict with gperftools

Wed Jun 5 14:00:00 2013 idonmezAATTsuse.com
- Update to version 3.4.0

Thu Mar 7 13:00:00 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.

* 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).
