* Wed Oct 04 2017 mliska@suse.cz
- Add 0001-ARM-Don-t-extend-bit-LG_VADDR-to-compute-high-addres.patch:
fixes #979.
* Tue Sep 12 2017 mliska@suse.cz
- Add 0001-remove-CPU_SPINWAIT.patch:
revert 701daa5298b3befe2aff05ce590533165abb9ba4 in order to fix #761.
* Tue Sep 12 2017 mliska@suse.cz
- Update to version 5.0.1
Bug fixes:
* Update decay->nunpurged before purging, in order to avoid potential
update races and subsequent incorrect purging volume.
([37]@interwq)
* Only abort on dlsym(3) error if the failure impacts an enabled
feature (lazy locking and/or background threads). This mitigates an
initialization failure bug for which we still do not have a clear
reproduction test case. ([38]@interwq)
* Modify tsd management so that it neither crashes nor leaks if a
thread's only allocation activity is to call free() after TLS
destructors have been executed. This behavior was observed when
operating with GNU libc, and is unlikely to be an issue with other
libc implementations. ([39]@interwq)
* Mask signals during background thread creation. This prevents
signals from being inadvertently delivered to background threads.
([40]@jasone, [41]@davidtgoldblatt, [42]@interwq)
* Avoid inactivity checks within background threads, in order to
prevent recursive mutex acquisition. ([43]@interwq)
* Fix extent_grow_retained() to use the specified hooks when the
arena.<i>.extent_hooks mallctl is used to override the default
hooks. ([44]@interwq)
* Add missing reentrancy support for custom extent hooks which
allocate. ([45]@interwq)
* Post-fork(2), re-initialize the list of tcaches associated with
each arena to contain no tcaches except the forking thread's.
([46]@interwq)
* Add missing post-fork(2) mutex reinitialization for
extent_grow_mtx. This fixes potential deadlocks after fork(2).
([47]@interwq)
* Enforce minimum autoconf version (currently 2.68), since 2.63 is
known to generate corrupt configure scripts. ([48]@jasone)
* Ensure that the configured page size (--with-lg-page) is no larger
than the configured huge page size (--with-lg-hugepage).
([49]@jasone)
New features:
* Implement optional per-CPU arena support; threads choose which
arena to use based on current CPU rather than on fixed
thread-->arena associations. ([59]@interwq)
* Implement two-phase decay of unused dirty pages. Pages transition
from dirty-->muzzy-->clean, where the first phase transition relies
on madvise(... MADV_FREE) semantics, and the second phase
transition discards pages such that they are replaced with
demand-zeroed pages on next access. ([60]@jasone)
* Increase decay time resolution from seconds to milliseconds.
([61]@jasone)
* Implement opt-in per CPU background threads, and use them for
asynchronous decay-driven unused dirty page purging. ([62]@interwq)
* Add mutex profiling, which collects a variety of statistics useful
for diagnosing overhead/contention issues. ([63]@interwq)
* Add C++ new/delete operator bindings. ([64]@djwatson)
* Support manually created arena destruction, such that all data and
metadata are discarded. Add MALLCTL_ARENAS_DESTROYED for accessing
merged stats associated with destroyed arenas. ([65]@jasone)
* Add MALLCTL_ARENAS_ALL as a fixed index for use in accessing
merged/destroyed arena statistics via mallctl. ([66]@jasone)
* Add opt.abort_conf to optionally abort if invalid configuration
options are detected during initialization. ([67]@interwq)
* Add opt.stats_print_opts, so that e.g. JSON output can be selected
for the stats dumped during exit if opt.stats_print is true.
([68]@jasone)
* Add --with-version=VERSION for use when embedding jemalloc into
another project's git repository. ([69]@jasone)
* Add --disable-thp to support cross compiling. ([70]@jasone)
* Add --with-lg-hugepage to support cross compiling. ([71]@jasone)
* Add mallctl interfaces (various authors):

time,max_num_thds,num_owner_switch}
Portability improvements:
* Improve reentrant allocation support, such that deadlock is less
likely if e.g. a system library call in turn allocates memory.
([72]@davidtgoldblatt, [73]@interwq)
* Support static linking of jemalloc with glibc. ([74]@djwatson)
Optimizations and refactors:
* Organize virtual memory as "extents" of virtual memory pages,
rather than as naturally aligned "chunks", and store all metadata
in arbitrarily distant locations. This reduces virtual memory
external fragmentation, and will interact better with huge pages
(not yet explicitly supported). ([75]@jasone)
* Fold large and huge size classes together; only small and large
size classes remain. ([76]@jasone)
* Unify the allocation paths, and merge most fast-path branching
decisions. ([77]@davidtgoldblatt, [78]@interwq)
* Embed per thread automatic tcache into thread-specific data, which
reduces conditional branches and dereferences. Also reorganize
tcache to increase fast-path data locality. ([79]@interwq)
* Rewrite atomics to closely model the C11 API, convert various
synchronization from mutex-based to atomic, and use the explicit
memory ordering control to resolve various hypothetical races
without increasing synchronization overhead. ([80]@davidtgoldblatt)
* Extensively optimize rtree via various methods:
+ Add multiple layers of rtree lookup caching, since rtree
lookups are now part of fast-path deallocation. ([81]@interwq)
+ Determine rtree layout at compile time. ([82]@jasone)
+ Make the tree shallower for common configurations.
([83]@jasone)
+ Embed the root node in the top-level rtree data structure,
thus avoiding one level of indirection. ([84]@jasone)
+ Further specialize leaf elements as compared to internal node
elements, and directly embed extent metadata needed for
fast-path deallocation. ([85]@jasone)
+ Ignore leading always-zero address bits
(architecture-specific). ([86]@jasone)
* Reorganize headers (ongoing work) to make them hermetic, and
disentangle various module dependencies. ([87]@davidtgoldblatt)
* Convert various internal data structures such as size class
metadata from boot-time-initialized to compile-time-initialized.
Propagate resulting data structure simplifications, such as making
arena metadata fixed-size. ([88]@jasone)
* Simplify size class lookups when constrained to size classes that
are multiples of the page size. This speeds lookups, but the
primary benefit is complexity reduction in code that was the source
of numerous regressions. ([89]@jasone)
* Lock individual extents when possible for localized extent
operations, rather than relying on a top-level arena lock.
([90]@davidtgoldblatt, [91]@jasone)
* Use first fit layout policy instead of best fit, in order to
improve packing. ([92]@jasone)
* If munmap(2) is not in use, use an exponential series to grow each
arena's virtual memory, so that the number of disjoint virtual
memory mappings remains low. ([93]@jasone)
* Implement per arena base allocators, so that arenas never share any
virtual memory pages. ([94]@jasone)
* Automatically generate private symbol name mangling macros.
([95]@jasone)
Incompatible changes:

hooks. ([96]@jasone)

* Remove --disable-cc-silence. ([103]@jasone)
* Remove --enable-code-coverage. ([104]@jasone)
* Remove --disable-munmap (replaced by opt.retain). ([105]@jasone)
* Remove Valgrind support. ([106]@jasone)
* Remove quarantine support. ([107]@jasone)

unks}
Bug fixes:
* Improve interval-based profile dump triggering to dump only one
profile when a single allocation's size exceeds the interval.
([109]@jasone)
* Use prefixed function names (as controlled by
- -with-jemalloc-prefix) when pruning backtrace frames in jeprof.
([110]@jasone)
* Fri Mar 10 2017 idonmez@suse.com
- Update to version 4.5.0
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.
* Sun Dec 04 2016 idonmez@suse.com
- Update to version 4.4.0
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.
* Tue Nov 08 2016 idonmez@suse.com
- Update to version 4.3.1
* Fix a severe virtual memory leak. This regression was first
released in 4.3.0.
* Sat Nov 05 2016 idonmez@suse.com
- Update to version 4.3.0
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
memory map fragmentation issues on Windows.
* Fix TSD fetches to avoid (recursive) allocation. This is relevant to
non-TLS and Windows configurations.
* Fix malloc_conf overriding to work on Windows.
* Forcibly disable lazy-lock on Windows (was forcibly *enabled*).
* Thu Jun 09 2016 idonmez@suse.com
- Update to version 4.2.1
* Fix bootstrapping issues for configurations that require
allocation during tsd initialization (e.g. --disable-tls).
* Fix gettimeofday() version of nstime_update().
* Fix Valgrind regressions in calloc() and chunk_alloc_wrapper().
* Fix potential VM map fragmentation regression.
* Fix opt_zero-triggered in-place huge reallocation zeroing.
* Fix heap profiling context leaks in reallocation edge cases.
* Fri May 13 2016 idonmez@suse.com
- Update to version 4.2.0
* 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.
* Wed May 04 2016 idonmez@suse.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
* Wed Apr 20 2016 jslaby@suse.com
- add disable_oom_test.patch
* Mon Feb 29 2016 idonmez@suse.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.<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.
* Sun Feb 14 2016 olaf@aepfle.de
- Fix build/test in SLE_11 by using gcc48
* Sat Oct 24 2015 idonmez@suse.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 idonmez@suse.com
- Update to version 4.0.3
* See included ChangeLog for complete changes.
