New features:
* Add --disable-thp and the opt.thp mallctl to provide opt-out
mechanisms for transparent huge page integration.
* Restructure *CFLAGS configuration, so that CFLAGS behaves
typically, and EXTRA_CFLAGS provides a way to specify e.g.
-Werror during building, but not during configuration.
Bug fixes:
* Fix DSS (sbrk(2)-based) allocation. This regression was first
released in 4.3.0.
* Handle race in per size class utilization computation.
This functionality was first released in 4.0.0.
* Fix lock order reversal during gdump.
* Fix/refactor tcache synchronization. This regression was
first released in 4.0.0.
* Fix various JSON-formatted malloc_stats_print() bugs.
This functionality was first released in 4.3.0.
* Fix huge-aligned allocation. This regression was first
released in 4.4.0.
* When transparent huge page integration is enabled, detect
what state pages start in according to the kernel's current
operating mode, and only convert arena chunks to non-huge
during purging if that is not their initial state.
This functionality was first released in 4.4.0.
* Fix lg_chunk clamping for the --enable-cache-oblivious
--disable-fill case. This regression was first released
in 4.0.0.

Optimizations:
* Add extent serial numbers and use them where appropriate as a
sort key that is higher priority than address, so that the
allocation policy prefers older extents. This tends to improve
locality (decrease fragmentation) when memory grows downward.
* Refactor madvise(2) configuration so that MADV_FREE is detected
and utilized on Linux 4.5 and newer.
* Mark partially purged arena chunks as non-huge-page.
This improves interaction with Linux's transparent huge page
functionality.
Bug fixes:
* Fix size class computations for edge conditions involving
extremely large allocations. This regression was first
released in 4.0.0.
* Remove overly restrictive assertions related to the cactive
statistic. This regression was first released in 4.1.0.
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/jemalloc?expand=0&rev=49
New features:
* Add "J" (JSON) support to malloc_stats_print().
* Add Cray compiler support.
Optimizations:
* Add/use adaptive spinning for bootstrapping and radix tree node
initialization.
Bugfixes:
* Fix large allocation to search starting in the optimal size
class heap, which can substantially reduce virtual memory churn
and fragmentation. This regression was first released in 4.0.0.
* Fix stats.arenas.<i>.nthreads accounting.
* Fix and simplify decay-based purging.
* Make DSS (sbrk(2)-related) operations lockless, which resolves
potential deadlocks during thread exit.
* Fix over-sized allocation of radix tree leaf nodes.
* Fix over-sized allocation of arena_t (plus associated stats) data
structures.
* Fix EXTRA_CFLAGS to not affect configuration.
* Fix a Valgrind integration bug.
* Disallow 0x5a junk filling when running in Valgrind.
* Fix a file descriptor leak on Linux. This regression was
first released in 4.2.0.
* Fix static linking of jemalloc with glibc.
* Use syscall(2) rather than {open,read,close}(2) during boot on Linux.
This works around other libraries' system call wrappers performing
reentrant allocation.
* Fix OS X default zone replacement to work with OS X 10.12.
* Fix cached memory management to avoid needless commit/decommit
operations during purging, which resolves permanent virtual

* Add the arena.<i>.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.<i>.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.
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/jemalloc?expand=0&rev=42
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/jemalloc?expand=0&rev=39
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.
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/jemalloc?expand=0&rev=33
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/jemalloc?expand=0&rev=23
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/jemalloc?expand=0&rev=17
* 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
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/jemalloc?expand=0&rev=15
* 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
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/jemalloc?expand=0&rev=10
* Add clipping support to lg_chunk option processing.
* Add the --enable-ivsalloc option.
* Add the --without-export option.
* Add the --disable-zone-allocator option.
* 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.
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/jemalloc?expand=0&rev=8
- Update to new upstream release 3.0.0
* Implement Valgrind support, redzones, and quarantine.
* Add support for additional architectures: MIPS, SH4, Tilera
* Add nallocm(), which rounds a request size up to the nearest size
class without actually allocating.
* Implement aligned_alloc()
* Add the "thread.tcache.enabled" and "opt.prof_final" mallctls.
* Update pprof (from gperftools 2.0).
* (For more, see the ChangeLog file in this RPM package.)
