(@jasone) + - Fix hashing functions to avoid unaligned memory accesses (and resulting + crashes).

(@jasone) + - Fix malloc_stats_print() to print opt.narenas correctly. (@jasone) + - Fix MSVC-specific build/test issues. (@rustyx, @yuslepukhin) + - Fix a variety of test failures that were due to test fragility rather than + core bugs. (@jasone) + +* 4.1.0 (February 28, 2016) + + This release is primarily about optimizations, but it also incorporates a lot + of portability-motivated refactoring and enhancements. Many people worked on + this release, to an extent that even with the omission here of minor changes + (see git revision history), and of the people who reported and diagnosed + issues, so much of the work was contributed that starting with this release, + changes are annotated with author credits to help reflect the collaborative + effort involved. + + 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 + (@jasone, @cevans87) + - 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. (@jasone) + - Add MS Visual Studio 2015 support. (@rustyx, @yuslepukhin) + - Make *allocx() size class overflow behavior defined. The maximum + size class is now less than PTRDIFF_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. (@jasone) + - jeprof: + + Add raw heap profile support. (@jasone) + + Add --retain and --exclude for backtrace symbol filtering. (@jasone) + + Optimizations: + - Optimize the fast path to combine various bootstrapping and configuration + checks and execute more streamlined code in the common case. (@interwq) + - 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%. (@djwatson) + - Separate arena_avail trees, which substantially speeds up run tree + operations. (@djwatson) + - Use memoization (boot-time-computed table) for run quantization. Separate + arena_avail trees reduced the importance of this optimization. (@jasone) + - Attempt mmap-based in-place huge reallocation. This can dramatically speed + up incremental huge reallocation. (@jasone) + + Incompatible changes: + - Make opt.narenas unsigned rather than size_t. (@jasone) + + Bug fixes: + - Fix stats.cactive accounting regression. (@rustyx, @jasone) + - Handle unaligned keys in hash(). This caused problems for some ARM systems. + (@jasone, @cferris1000) + - Refactor arenas array. In addition to fixing a fork-related deadlock, this + makes arena lookups faster and simpler. (@jasone) + - 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. + (@buchgr) + - Fix a potential tsd cleanup leak. (@cferris1000, @jasone) + - Fix run quantization. In practice this bug had no impact unless + applications requested memory with alignment exceeding one page. + (@jasone, @djwatson) + - 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..{dss,lg_dirty_mult,decay_time,pactive,pdirty} for + --disable-stats case. (@jasone) + +* 4.0.4 (October 24, 2015) + + This bugfix release fixes another xallocx() regression. No other regressions + have come to light in over a month, so this is likely a good starting point + for people who prefer to wait for "dot one" releases with all the major issues + shaken out. + + Bug fixes: + - 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. + +* 4.0.3 (September 24, 2015) + + This bugfix release continues the trend of xallocx() and heap profiling fixes. + + Bug fixes: + - Fix xallocx(..., MALLOCX_ZERO) to zero all trailing bytes of large + allocations when --enable-cache-oblivious configure option is enabled. + - Fix xallocx(..., MALLOCX_ZERO) to zero trailing bytes of huge allocations + when resizing from/to a size class that is not a multiple of the chunk size. + - Fix prof_tctx_dump_iter() to filter out nodes that were created after heap + profile dumping started. + - Work around a potentially bad thread-specific data initialization + interaction with NPTL (glibc's pthreads implementation). + +* 4.0.2 (September 21, 2015) + + This bugfix release addresses a few bugs specific to heap profiling. + + Bug fixes: + - Fix ixallocx_prof_sample() to never modify nor create sampled small + allocations. xallocx() is in general incapable of moving small allocations, + so this fix removes buggy code without loss of generality. + - Fix irallocx_prof_sample() to always allocate large regions, even when + alignment is non-zero. + - Fix prof_alloc_rollback() to read tdata from thread-specific data rather + than dereferencing a potentially invalid tctx. + +* 4.0.1 (September 15, 2015) + + This is a bugfix release that is somewhat high risk due to the amount of + refactoring required to address deep xallocx() problems. As a side effect of + these fixes, xallocx() now tries harder to partially fulfill requests for + optional extra space. Note that a couple of minor heap profiling + optimizations are included, but these are better thought of as performance + fixes that were integral to disovering most of the other bugs. + + Optimizations: + - Avoid a chunk metadata read in arena_prof_tctx_set(), since it is in the + fast path when heap profiling is enabled. Additionally, split a special + case out into arena_prof_tctx_reset(), which also avoids chunk metadata + reads. + - Optimize irallocx_prof() to optimistically update the sampler state. The + prior implementation appears to have been a holdover from when + rallocx()/xallocx() functionality was combined as rallocm(). + + Bug fixes: + - Fix TLS configuration such that it is enabled by default for platforms on + which it works correctly. + - Fix arenas_cache_cleanup() and arena_get_hard() to handle + allocation/deallocation within the application's thread-specific data + cleanup functions even after arenas_cache is torn down. + - Fix xallocx() bugs related to size+extra exceeding HUGE_MAXCLASS. + - Fix chunk purge hook calls for in-place huge shrinking reallocation to + specify the old chunk size rather than the new chunk size. This bug caused + no correctness issues for the default chunk purge function, but was + visible to custom functions set via the "arena..chunk_hooks" mallctl. + - Fix heap profiling bugs: + + Fix heap profiling to distinguish among otherwise identical sample sites + with interposed resets (triggered via the "prof.reset" mallctl). This bug + could cause data structure corruption that would most likely result in a + segfault. + + Fix irealloc_prof() to prof_alloc_rollback() on OOM. + + Make one call to prof_active_get_unlocked() per allocation event, and use + the result throughout the relevant functions that handle an allocation + event. Also add a missing check in prof_realloc(). These fixes protect + allocation events against concurrent prof_active changes. + + Fix ixallocx_prof() to pass usize_max and zero to ixallocx_prof_sample() + in the correct order. + + Fix prof_realloc() to call prof_free_sampled_object() after calling + prof_malloc_sample_object(). Prior to this fix, if tctx and old_tctx were + the same, the tctx could have been prematurely destroyed. + - Fix portability bugs: + + Don't bitshift by negative amounts when encoding/decoding run sizes in + chunk header maps. This affected systems with page sizes greater than 8 + KiB. + + Rename index_t to szind_t to avoid an existing type on Solaris. + + Add JEMALLOC_CXX_THROW to the memalign() function prototype, in order to + match glibc and avoid compilation errors when including both + jemalloc/jemalloc.h and malloc.h in C++ code. + + Don't assume that /bin/sh is appropriate when running size_classes.sh + during configuration. + + Consider __sparcv9 a synonym for __sparc64__ when defining LG_QUANTUM. + + Link tests to librt if it contains clock_gettime(2). + +* 4.0.0 (August 17, 2015) + + This version contains many speed and space optimizations, both minor and + major. The major themes are generalization, unification, and simplification. + Although many of these optimizations cause no visible behavior change, their + cumulative effect is substantial. + + New features: + - Normalize size class spacing to be consistent across the complete size + range. By default there are four size classes per size doubling, but this + is now configurable via the --with-lg-size-class-group option. Also add the + --with-lg-page, --with-lg-page-sizes, --with-lg-quantum, and + --with-lg-tiny-min options, which can be used to tweak page and size class + settings. Impacts: + + Worst case performance for incrementally growing/shrinking reallocation + is improved because there are far fewer size classes, and therefore + copying happens less often. + + Internal fragmentation is limited to 20% for all but the smallest size + classes (those less than four times the quantum). (1B + 4 KiB) + and (1B + 4 MiB) previously suffered nearly 50% internal fragmentation. + + Chunk fragmentation tends to be lower because there are fewer distinct run + sizes to pack. + - Add support for explicit tcaches. The "tcache.create", "tcache.flush", and + "tcache.destroy" mallctls control tcache lifetime and flushing, and the + MALLOCX_TCACHE(tc) and MALLOCX_TCACHE_NONE flags to the *allocx() API + control which tcache is used for each operation. + - Implement per thread heap profiling, as well as the ability to + enable/disable heap profiling on a per thread basis. Add the "prof.reset", + "prof.lg_sample", "thread.prof.name", "thread.prof.active", + "opt.prof_thread_active_init", "prof.thread_active_init", and + "thread.prof.active" mallctls. + - Add support for per arena application-specified chunk allocators, configured + via the "arena..chunk_hooks" mallctl. + - Refactor huge allocation to be managed by arenas, so that arenas now + function as general purpose independent allocators. This is important in + the context of user-specified chunk allocators, aside from the scalability + benefits. Related new statistics: + + The "stats.arenas..huge.allocated", "stats.arenas..huge.nmalloc", + "stats.arenas..huge.ndalloc", and "stats.arenas..huge.nrequests" + mallctls provide high level per arena huge allocation statistics. + + The "arenas.nhchunks", "arenas.hchunk..size", + "stats.arenas..hchunks..nmalloc", + "stats.arenas..hchunks..ndalloc", + "stats.arenas..hchunks..nrequests", and + "stats.arenas..hchunks..curhchunks" mallctls provide per size class + statistics. + - Add the 'util' column to malloc_stats_print() output, which reports the + proportion of available regions that are currently in use for each small + size class. + - Add "alloc" and "free" modes for for junk filling (see the "opt.junk" + mallctl), so that it is possible to separately enable junk filling for + allocation versus deallocation. + - Add the jemalloc-config script, which provides information about how + jemalloc was configured, and how to integrate it into application builds. + - Add metadata statistics, which are accessible via the "stats.metadata", + "stats.arenas..metadata.mapped", and + "stats.arenas..metadata.allocated" mallctls. + - Add the "stats.resident" mallctl, which reports the upper limit of + physically resident memory mapped by the allocator. + - Add per arena control over unused dirty page purging, via the + "arenas.lg_dirty_mult", "arena..lg_dirty_mult", and + "stats.arenas..lg_dirty_mult" mallctls. + - Add the "prof.gdump" mallctl, which makes it possible to toggle the gdump + feature on/off during program execution. + - Add sdallocx(), which implements sized deallocation. The primary + optimization over dallocx() is the removal of a metadata read, which often + suffers an L1 cache miss. + - Add missing header includes in jemalloc/jemalloc.h, so that applications + only have to #include . + - Add support for additional platforms: + + Bitrig + + Cygwin + + DragonFlyBSD + + iOS + + OpenBSD + + OpenRISC/or1k + + Optimizations: + - Maintain dirty runs in per arena LRUs rather than in per arena trees of + dirty-run-containing chunks. In practice this change significantly reduces + dirty page purging volume. + - Integrate whole chunks into the unused dirty page purging machinery. This + reduces the cost of repeated huge allocation/deallocation, because it + effectively introduces a cache of chunks. + - Split the arena chunk map into two separate arrays, in order to increase + cache locality for the frequently accessed bits. + - Move small run metadata out of runs, into arena chunk headers. This reduces + run fragmentation, smaller runs reduce external fragmentation for small size + classes, and packed (less uniformly aligned) metadata layout improves CPU + cache set distribution. + - Randomly distribute large allocation base pointer alignment relative to page + boundaries in order to more uniformly utilize CPU cache sets. This can be + disabled via the --disable-cache-oblivious configure option, and queried via + the "config.cache_oblivious" mallctl. + - Micro-optimize the fast paths for the public API functions. + - Refactor thread-specific data to reside in a single structure. This assures + that only a single TLS read is necessary per call into the public API. + - Implement in-place huge allocation growing and shrinking. + - Refactor rtree (radix tree for chunk lookups) to be lock-free, and make + additional optimizations that reduce maximum lookup depth to one or two + levels. This resolves what was a concurrency bottleneck for per arena huge + allocation, because a global data structure is critical for determining + which arenas own which huge allocations. + + Incompatible changes: + - Replace --enable-cc-silence with --disable-cc-silence to suppress spurious + warnings by default. + - Assure that the constness of malloc_usable_size()'s return type matches that + of the system implementation. + - Change the heap profile dump format to support per thread heap profiling, + rename pprof to jeprof, and enhance it with the --thread= option. As a + result, the bundled jeprof must now be used rather than the upstream + (gperftools) pprof. + - Disable "opt.prof_final" by default, in order to avoid atexit(3), which can + internally deadlock on some platforms. + - Change the "arenas.nlruns" mallctl type from size_t to unsigned. + - Replace the "stats.arenas..bins..allocated" mallctl with + "stats.arenas..bins..curregs". + - Ignore MALLOC_CONF in set{uid,gid,cap} binaries. + - Ignore MALLOCX_ARENA(a) in dallocx(), in favor of using the + MALLOCX_TCACHE(tc) and MALLOCX_TCACHE_NONE flags to control tcache usage. + + Removed features: + - Remove the *allocm() API, which is superseded by the *allocx() API. + - Remove the --enable-dss options, and make dss non-optional on all platforms + which support sbrk(2). + - Remove the "arenas.purge" mallctl, which was obsoleted by the + "arena..purge" mallctl in 3.1.0. + - Remove the unnecessary "opt.valgrind" mallctl; jemalloc automatically + detects whether it is running inside Valgrind. + - Remove the "stats.huge.allocated", "stats.huge.nmalloc", and + "stats.huge.ndalloc" mallctls. + - Remove the --enable-mremap option. + - Remove the "stats.chunks.current", "stats.chunks.total", and + "stats.chunks.high" mallctls. + + Bug fixes: + - Fix the cactive statistic to decrease (rather than increase) when active + memory decreases. This regression was first released in 3.5.0. + - Fix OOM handling in memalign() and valloc(). A variant of this bug existed + in all releases since 2.0.0, which introduced these functions. + - Fix an OOM-related regression in arena_tcache_fill_small(), which could + cause cache corruption on OOM. This regression was present in all releases + from 2.2.0 through 3.6.0. + - Fix size class overflow handling for malloc(), posix_memalign(), memalign(), + calloc(), and realloc() when profiling is enabled. + - Fix the "arena..dss" mallctl to return an error if "primary" or + "secondary" precedence is specified, but sbrk(2) is not supported. + - Fix fallback lg_floor() implementations to handle extremely large inputs. + - Ensure the default purgeable zone is after the default zone on OS X. + - Fix latent bugs in atomic_*(). + - Fix the "arena..dss" mallctl to handle read-only calls. + - Fix tls_model configuration to enable the initial-exec model when possible. + - Mark malloc_conf as a weak symbol so that the application can override it. + - Correctly detect glibc's adaptive pthread mutexes. + - Fix the --without-export configure option. + +* 3.6.0 (March 31, 2014) + + This version contains a critical bug fix for a regression present in 3.5.0 and + 3.5.1. + + Bug fixes: + - Fix a regression in arena_chunk_alloc() that caused crashes during + small/large allocation if chunk allocation failed. In the absence of this + bug, chunk allocation failure would result in allocation failure, e.g. NULL + return from malloc(). This regression was introduced in 3.5.0. + - Fix backtracing for gcc intrinsics-based backtracing by specifying + -fno-omit-frame-pointer to gcc. Note that the application (and all the + libraries it links to) must also be compiled with this option for + backtracing to be reliable. + - Use dss allocation precedence for huge allocations as well as small/large + allocations. + - Fix test assertion failure message formatting. This bug did not manifest on + x86_64 systems because of implementation subtleties in va_list. + - Fix inconsequential test failures for hash and SFMT code. + + New features: + - Support heap profiling on FreeBSD. This feature depends on the proc + filesystem being mounted during heap profile dumping. + +* 3.5.1 (February 25, 2014) + + This version primarily addresses minor bugs in test code. + + Bug fixes: + - Configure Solaris/Illumos to use MADV_FREE. + - Fix junk filling for mremap(2)-based huge reallocation. This is only + relevant if configuring with the --enable-mremap option specified. + - Avoid compilation failure if 'restrict' C99 keyword is not supported by the + compiler. + - Add a configure test for SSE2 rather than assuming it is usable on i686 + systems. This fixes test compilation errors, especially on 32-bit Linux + systems. + - Fix mallctl argument size mismatches (size_t vs. uint64_t) in the stats unit + test. + - Fix/remove flawed alignment-related overflow tests. + - Prevent compiler optimizations that could change backtraces in the + prof_accum unit test. + +* 3.5.0 (January 22, 2014) + + This version focuses on refactoring and automated testing, though it also + includes some non-trivial heap profiling optimizations not mentioned below. + + New features: + - 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()/rallocm() share with posix_memalign(). Note that *allocm() is + slated for removal in the next non-bugfix release. + - Add support for LinuxThreads. + + Bug fixes: + - 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. + +* 3.4.1 (October 20, 2013) + + Bug fixes: + - 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 (relevant to tcache and prof + code) + - 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. + +* 3.4.0 (June 2, 2013) + + This version is essentially a small bugfix release, but the addition of + aarch64 support requires that the minor version be incremented. + + Bug fixes: + - Fix race-triggered deadlocks in chunk_record(). These deadlocks were + typically triggered by multiple threads concurrently deallocating huge + objects. + + New features: + - Add support for the aarch64 architecture. + +* 3.3.1 (March 6, 2013) + + This version fixes bugs that are typically encountered only when utilizing + custom run-time options. + + Bug fixes: + - 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. On FreeBSD, NetBSD, and OS X, it could cause + corruption if allocating via sbrk(2) (unlikely unless running with the + "dss:primary" option specified). This was completely harmless on Linux + unless using mlockall(2) (and unlikely even then, unless the + --disable-munmap configure option or the "dss:primary" option was + specified). This regression was introduced in 3.1.0 by the + mlockall(2)/madvise(2) interaction fix. + - 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. + - Fix two quarantine bugs: + + 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. + +* 3.3.0 (January 23, 2013) + + This version includes a few minor performance improvements in addition to the + listed new features and bug fixes. + + New features: + - Add clipping support to lg_chunk option processing. + - Add the --enable-ivsalloc option. + - Add the --without-export option. + - Add the --disable-zone-allocator option. + + Bug fixes: + - Fix "arenas.extend" mallctl to output the number of arenas. + - Fix chunk_recycle() to unconditionally inform Valgrind that returned memory + is undefined. + - Fix build break on FreeBSD related to alloca.h. + +* 3.2.0 (November 9, 2012) + + In addition to a couple of bug fixes, this version modifies page run + allocation and dirty page purging algorithms in order to better control + page-level virtual memory fragmentation. + + Incompatible changes: + - Change the "opt.lg_dirty_mult" default from 5 to 3 (32:1 to 8:1). + + Bug fixes: + - Fix dss/mmap allocation precedence code to use recyclable mmap memory only + after primary dss allocation fails. + - Fix deadlock in the "arenas.purge" mallctl. This regression was introduced + in 3.1.0 by the addition of the "arena..purge" mallctl. + +* 3.1.0 (October 16, 2012) + + New features: + - Auto-detect whether running inside Valgrind, thus removing the need to + manually specify MALLOC_CONF=valgrind:true. + - Add the "arenas.extend" mallctl, which allows applications to create + manually managed arenas. + - Add the ALLOCM_ARENA() flag for {,r,d}allocm(). + - Add the "opt.dss", "arena..dss", and "stats.arenas..dss" mallctls, + which provide control over dss/mmap precedence. + - Add the "arena..purge" mallctl, which obsoletes "arenas.purge". + - Define LG_QUANTUM for hppa. + + Incompatible changes: + - Disable tcache by default if running inside Valgrind, in order to avoid + making unallocated objects appear reachable to Valgrind. + - Drop const from malloc_usable_size() argument on Linux. + + Bug fixes: + - Fix heap profiling crash if sampled object is freed via realloc(p, 0). + - Remove const from __*_hook variable declarations, so that glibc can modify + them during process forking. + - Fix mlockall(2)/madvise(2) interaction. + - Fix fork(2)-related deadlocks. + - Fix error return value for "thread.tcache.enabled" mallctl. + +* 3.0.0 (May 11, 2012) + + Although this version adds some major new features, the primary focus is on + internal code cleanup that facilitates maintainability and portability, most + of which is not reflected in the ChangeLog. This is the first release to + incorporate substantial contributions from numerous other developers, and the + result is a more broadly useful allocator (see the git revision history for + contribution details). Note that the license has been unified, thanks to + Facebook granting a license under the same terms as the other copyright + holders (see COPYING). + + New features: + - Implement Valgrind support, redzones, and quarantine. + - Add support for additional platforms: + + FreeBSD + + Mac OS X Lion + + MinGW + + Windows (no support yet for replacing the system malloc) + - Add support for additional architectures: + + MIPS + + SH4 + + Tilera + - Add support for cross compiling. + - Add nallocm(), which rounds a request size up to the nearest size class + without actually allocating. + - Implement aligned_alloc() (blame C11). + - Add the "thread.tcache.enabled" mallctl. + - Add the "opt.prof_final" mallctl. + - Update pprof (from gperftools 2.0). + - Add the --with-mangling option. + - Add the --disable-experimental option. + - Add the --disable-munmap option, and make it the default on Linux. + - Add the --enable-mremap option, which disables use of mremap(2) by default. + + Incompatible changes: + - Enable stats by default. + - Enable fill by default. + - Disable lazy locking by default. + - Rename the "tcache.flush" mallctl to "thread.tcache.flush". + - Rename the "arenas.pagesize" mallctl to "arenas.page". + - Change the "opt.lg_prof_sample" default from 0 to 19 (1 B to 512 KiB). + - Change the "opt.prof_accum" default from true to false. + + Removed features: + - Remove the swap feature, including the "config.swap", "swap.avail", + "swap.prezeroed", "swap.nfds", and "swap.fds" mallctls. + - Remove highruns statistics, including the + "stats.arenas..bins..highruns" and + "stats.arenas..lruns..highruns" mallctls. + - As part of small size class refactoring, remove the "opt.lg_[qc]space_max", + "arenas.cacheline", "arenas.subpage", "arenas.[tqcs]space_{min,max}", and + "arenas.[tqcs]bins" mallctls. + - Remove the "arenas.chunksize" mallctl. + - Remove the "opt.lg_prof_tcmax" option. + - Remove the "opt.lg_prof_bt_max" option. + - Remove the "opt.lg_tcache_gc_sweep" option. + - Remove the --disable-tiny option, including the "config.tiny" mallctl. + - Remove the --enable-dynamic-page-shift configure option. + - Remove the --enable-sysv configure option. + + Bug fixes: + - Fix a statistics-related bug in the "thread.arena" mallctl that could cause + invalid statistics and crashes. + - Work around TLS deallocation via free() on Linux. This bug could cause + write-after-free memory corruption. + - Fix a potential deadlock that could occur during interval- and + growth-triggered heap profile dumps. + - Fix large calloc() zeroing bugs due to dropping chunk map unzeroed flags. + - Fix chunk_alloc_dss() to stop claiming memory is zeroed. This bug could + cause memory corruption and crashes with --enable-dss specified. + - Fix fork-related bugs that could cause deadlock in children between fork + and exec. + - Fix malloc_stats_print() to honor 'b' and 'l' in the opts parameter. + - Fix realloc(p, 0) to act like free(p). + - Do not enforce minimum alignment in memalign(). + - Check for NULL pointer in malloc_usable_size(). + - Fix an off-by-one heap profile statistics bug that could be observed in + interval- and growth-triggered heap profiles. + - Fix the "epoch" mallctl to update cached stats even if the passed in epoch + is 0. + - Fix bin->runcur management to fix a layout policy bug. This bug did not + affect correctness. + - Fix a bug in choose_arena_hard() that potentially caused more arenas to be + initialized than necessary. + - Add missing "opt.lg_tcache_max" mallctl implementation. + - Use glibc allocator hooks to make mixed allocator usage less likely. + - Fix build issues for --disable-tcache. + - Don't mangle pthread_create() when --with-private-namespace is specified. + +* 2.2.5 (November 14, 2011) + + Bug fixes: + - Fix huge_ralloc() race when using mremap(2). This is a serious bug that + could cause memory corruption and/or crashes. + - Fix huge_ralloc() to maintain chunk statistics. + - Fix malloc_stats_print(..., "a") output. + +* 2.2.4 (November 5, 2011) + + Bug fixes: + - Initialize arenas_tsd before using it. This bug existed for 2.2.[0-3], as + well as for --disable-tls builds in earlier releases. + - Do not assume a 4 KiB page size in test/rallocm.c. + +* 2.2.3 (August 31, 2011) + + This version fixes numerous bugs related to heap profiling. + + Bug fixes: + - Fix a prof-related race condition. This bug could cause memory corruption, + but only occurred in non-default configurations (prof_accum:false). + - Fix off-by-one backtracing issues (make sure that prof_alloc_prep() is + excluded from backtraces). + - Fix a prof-related bug in realloc() (only triggered by OOM errors). + - Fix prof-related bugs in allocm() and rallocm(). + - Fix prof_tdata_cleanup() for --disable-tls builds. + - Fix a relative include path, to fix objdir builds. + +* 2.2.2 (July 30, 2011) + + Bug fixes: + - Fix a build error for --disable-tcache. + - Fix assertions in arena_purge() (for real this time). + - Add the --with-private-namespace option. This is a workaround for symbol + conflicts that can inadvertently arise when using static libraries. + +* 2.2.1 (March 30, 2011) + + Bug fixes: + - Implement atomic operations for x86/x64. This fixes compilation failures + for versions of gcc that are still in wide use. + - Fix an assertion in arena_purge(). + +* 2.2.0 (March 22, 2011) + + This version incorporates several improvements to algorithms and data + structures that tend to reduce fragmentation and increase speed. + + New features: + - Add the "stats.cactive" mallctl. + - Update pprof (from google-perftools 1.7). + - Improve backtracing-related configuration logic, and add the + --disable-prof-libgcc option. + + Bug fixes: + - Change default symbol visibility from "internal", to "hidden", which + decreases the overhead of library-internal function calls. + - Fix symbol visibility so that it is also set on OS X. + - Fix a build dependency regression caused by the introduction of the .pic.o + suffix for PIC object files. + - Add missing checks for mutex initialization failures. + - Don't use libgcc-based backtracing except on x64, where it is known to work. + - Fix deadlocks on OS X that were due to memory allocation in + pthread_mutex_lock(). + - Heap profiling-specific fixes: + + Fix memory corruption due to integer overflow in small region index + computation, when using a small enough sample interval that profiling + context pointers are stored in small run headers. + + Fix a bootstrap ordering bug that only occurred with TLS disabled. + + Fix a rallocm() rsize bug. + + Fix error detection bugs for aligned memory allocation. + +* 2.1.3 (March 14, 2011) + + Bug fixes: + - Fix a cpp logic regression (due to the "thread.{de,}allocatedp" mallctl fix + for OS X in 2.1.2). + - Fix a "thread.arena" mallctl bug. + - Fix a thread cache stats merging bug. + +* 2.1.2 (March 2, 2011) + + Bug fixes: + - Fix "thread.{de,}allocatedp" mallctl for OS X. + - Add missing jemalloc.a to build system. + +* 2.1.1 (January 31, 2011) + + Bug fixes: + - Fix aligned huge reallocation (affected allocm()). + - Fix the ALLOCM_LG_ALIGN macro definition. + - Fix a heap dumping deadlock. + - Fix a "thread.arena" mallctl bug. + +* 2.1.0 (December 3, 2010) + + This version incorporates some optimizations that can't quite be considered + bug fixes. + + New features: + - Use Linux's mremap(2) for huge object reallocation when possible. + - Avoid locking in mallctl*() when possible. + - Add the "thread.[de]allocatedp" mallctl's. + - Convert the manual page source from roff to DocBook, and generate both roff + and HTML manuals. + + Bug fixes: + - Fix a crash due to incorrect bootstrap ordering. This only impacted + --enable-debug --enable-dss configurations. + - Fix a minor statistics bug for mallctl("swap.avail", ...). + +* 2.0.1 (October 29, 2010) + + Bug fixes: + - Fix a race condition in heap profiling that could cause undefined behavior + if "opt.prof_accum" were disabled. + - Add missing mutex unlocks for some OOM error paths in the heap profiling + code. + - Fix a compilation error for non-C99 builds. + +* 2.0.0 (October 24, 2010) + + This version focuses on the experimental *allocm() API, and on improved + run-time configuration/introspection. Nonetheless, numerous performance + improvements are also included. + + New features: + - Implement the experimental {,r,s,d}allocm() API, which provides a superset + of the functionality available via malloc(), calloc(), posix_memalign(), + realloc(), malloc_usable_size(), and free(). These functions can be used to + allocate/reallocate aligned zeroed memory, ask for optional extra memory + during reallocation, prevent object movement during reallocation, etc. + - Replace JEMALLOC_OPTIONS/JEMALLOC_PROF_PREFIX with MALLOC_CONF, which is + more human-readable, and more flexible. For example: + JEMALLOC_OPTIONS=AJP + is now: + MALLOC_CONF=abort:true,fill:true,stats_print:true + - Port to Apple OS X. Sponsored by Mozilla. + - Make it possible for the application to control thread-->arena mappings via + the "thread.arena" mallctl. + - Add compile-time support for all TLS-related functionality via pthreads TSD. + This is mainly of interest for OS X, which does not support TLS, but has a + TSD implementation with similar performance. + - Override memalign() and valloc() if they are provided by the system. + - Add the "arenas.purge" mallctl, which can be used to synchronously purge all + dirty unused pages. + - Make cumulative heap profiling data optional, so that it is possible to + limit the amount of memory consumed by heap profiling data structures. + - Add per thread allocation counters that can be accessed via the + "thread.allocated" and "thread.deallocated" mallctls. + + Incompatible changes: + - Remove JEMALLOC_OPTIONS and malloc_options (see MALLOC_CONF above). + - Increase default backtrace depth from 4 to 128 for heap profiling. + - Disable interval-based profile dumps by default. + + Bug fixes: + - Remove bad assertions in fork handler functions. These assertions could + cause aborts for some combinations of configure settings. + - Fix strerror_r() usage to deal with non-standard semantics in GNU libc. + - Fix leak context reporting. This bug tended to cause the number of contexts + to be underreported (though the reported number of objects and bytes were + correct). + - Fix a realloc() bug for large in-place growing reallocation. This bug could + cause memory corruption, but it was hard to trigger. + - Fix an allocation bug for small allocations that could be triggered if + multiple threads raced to create a new run of backing pages. + - Enhance the heap profiler to trigger samples based on usable size, rather + than request size. + - Fix a heap profiling bug due to sometimes losing track of requested object + size for sampled objects. + +* 1.0.3 (August 12, 2010) + + Bug fixes: + - Fix the libunwind-based implementation of stack backtracing (used for heap + profiling). This bug could cause zero-length backtraces to be reported. + - Add a missing mutex unlock in library initialization code. If multiple + threads raced to initialize malloc, some of them could end up permanently + blocked. + +* 1.0.2 (May 11, 2010) + + Bug fixes: + - Fix junk filling of large objects, which could cause memory corruption. + - Add MAP_NORESERVE support for chunk mapping, because otherwise virtual + memory limits could cause swap file configuration to fail. Contributed by + Jordan DeLong. + +* 1.0.1 (April 14, 2010) + + Bug fixes: + - Fix compilation when --enable-fill is specified. + - Fix threads-related profiling bugs that affected accuracy and caused memory + to be leaked during thread exit. + - Fix dirty page purging race conditions that could cause crashes. + - Fix crash in tcache flushing code during thread destruction. + +* 1.0.0 (April 11, 2010) + + This release focuses on speed and run-time introspection. Numerous + algorithmic improvements make this release substantially faster than its + predecessors. + + New features: + - Implement autoconf-based configuration system. + - Add mallctl*(), for the purposes of introspection and run-time + configuration. + - Make it possible for the application to manually flush a thread's cache, via + the "tcache.flush" mallctl. + - Base maximum dirty page count on proportion of active memory. + - Compute various additional run-time statistics, including per size class + statistics for large objects. + - Expose malloc_stats_print(), which can be called repeatedly by the + application. + - Simplify the malloc_message() signature to only take one string argument, + and incorporate an opaque data pointer argument for use by the application + in combination with malloc_stats_print(). + - Add support for allocation backed by one or more swap files, and allow the + application to disable over-commit if swap files are in use. + - Implement allocation profiling and leak checking. + + Removed features: + - Remove the dynamic arena rebalancing code, since thread-specific caching + reduces its utility. + + Bug fixes: + - Modify chunk allocation to work when address space layout randomization + (ASLR) is in use. + - Fix thread cleanup bugs related to TLS destruction. + - Handle 0-size allocation requests in posix_memalign(). + - Fix a chunk leak. The leaked chunks were never touched, so this impacted + virtual memory usage, but not physical memory usage. + +* linux_2008082[78]a (August 27/28, 2008) + + These snapshot releases are the simple result of incorporating Linux-specific + support into the FreeBSD malloc sources. + +-------------------------------------------------------------------------------- +vim:filetype=text:textwidth=80 diff --git a/src/third_party/jemalloc-4.2.1/INSTALL b/src/third_party/jemalloc-4.2.1/INSTALL new file mode 100644 index 0000000..6878716 --- /dev/null +++ b/src/third_party/jemalloc-4.2.1/INSTALL @@ -0,0 +1,414 @@ +Building and installing a packaged release of jemalloc can be as simple as +typing the following while in the root directory of the source tree: + + ./configure + make + make install + +If building from unpackaged developer sources, the simplest command sequence +that might work is: + + ./autogen.sh + make dist + make + make install + +Note that documentation is not built by the default target because doing so +would create a dependency on xsltproc in packaged releases, hence the +requirement to either run 'make dist' or avoid installing docs via the various +install_* targets documented below. + +=== Advanced configuration ===================================================== + +The 'configure' script supports numerous options that allow control of which +functionality is enabled, where jemalloc is installed, etc. Optionally, pass +any of the following arguments (not a definitive list) to 'configure': + +--help + Print a definitive list of options. + +--prefix= + Set the base directory in which to install. For example: + + ./configure --prefix=/usr/local + + will cause files to be installed into /usr/local/include, /usr/local/lib, + and /usr/local/man. + +--with-version=..--g + Use the specified version string rather than trying to generate one (if in + a git repository) or use existing the VERSION file (if present). + +--with-rpath= + Embed one or more library paths, so that libjemalloc can find the libraries + it is linked to. This works only on ELF-based systems. + +--with-mangling= + Mangle public symbols specified in which is a comma-separated list of + name:mangled pairs. + + For example, to use ld's --wrap option as an alternative method for + overriding libc's malloc implementation, specify something like: + + --with-mangling=malloc:__wrap_malloc,free:__wrap_free[...] + + Note that mangling happens prior to application of the prefix specified by + --with-jemalloc-prefix, and mangled symbols are then ignored when applying + the prefix. + +--with-jemalloc-prefix= + Prefix all public APIs with .

See the "opt.stats_print" + option documentation for usage details. + +--enable-ivsalloc + Enable validation code, which verifies that pointers reside within + jemalloc-owned chunks before dereferencing them. This incurs a minor + performance hit. + +--enable-prof + Enable heap profiling and leak detection functionality. See the "opt.prof" + option documentation for usage details. When enabled, there are several + approaches to backtracing, and the configure script chooses the first one + in the following list that appears to function correctly: + + + libunwind (requires --enable-prof-libunwind) + + libgcc (unless --disable-prof-libgcc) + + gcc intrinsics (unless --disable-prof-gcc) + +--enable-prof-libunwind + Use the libunwind library (http://www.nongnu.org/libunwind/) for stack + backtracing. + +--disable-prof-libgcc + Disable the use of libgcc's backtracing functionality. + +--disable-prof-gcc + Disable the use of gcc intrinsics for backtracing. + +--with-static-libunwind= + Statically link against the specified libunwind.a rather than dynamically + linking with -lunwind. + +--disable-tcache + Disable thread-specific caches for small objects.

This means jemalloc won't be hooked as + the default allocator on OSX/iOS. + +--enable-utrace + Enable utrace(2)-based allocation tracing. This feature is not broadly + portable (FreeBSD has it, but Linux and OS X do not). + +--enable-xmalloc + Enable support for optional immediate termination due to out-of-memory + errors, as is commonly implemented by "xmalloc" wrapper function for malloc. + See the "opt.xmalloc" option documentation for usage details. + +--enable-lazy-lock + Enable code that wraps pthread_create() to detect when an application + switches from single-threaded to multi-threaded mode, so that it can avoid + mutex locking/unlocking operations while in single-threaded mode. In + practice, this feature usually has little impact on performance unless + thread-specific caching is disabled. + +--disable-tls + Disable thread-local storage (TLS), which allows for fast access to + thread-local variables via the __thread keyword. If TLS is available, + jemalloc uses it for several purposes. + +--disable-cache-oblivious + Disable cache-oblivious large allocation alignment for large allocation + requests with no alignment constraints. If this feature is disabled, all + large allocations are page-aligned as an implementation artifact, which can + severely harm CPU cache utilization. However, the cache-oblivious layout + comes at the cost of one extra page per large allocation, which in the + most extreme case increases physical memory usage for the 16 KiB size class + to 20 KiB. + +--with-xslroot= + Specify where to find DocBook XSL stylesheets when building the + documentation. + +--with-lg-page= + Specify the base 2 log of the system page size. This option is only useful + when cross compiling, since the configure script automatically determines + the host's page size by default. + +--with-lg-page-sizes= + Specify the comma-separated base 2 logs of the page sizes to support. This + option may be useful when cross-compiling in combination with + --with-lg-page, but its primary use case is for integration with FreeBSD's + libc, wherein jemalloc is embedded. + +--with-lg-size-class-group= + Specify the base 2 log of how many size classes to use for each doubling in + size. By default jemalloc uses =2, which results in + e.g. the following size classes: + + [...], 64, + 80, 96, 112, 128, + 160, [...] + + =3 results in e.g. the following size classes: + + [...], 64, + 72, 80, 88, 96, 104, 112, 120, 128, + 144, [...] + + The minimal =0 causes jemalloc to only provide size + classes that are powers of 2: + + [...], + 64, + 128, + 256, + [...] + + An implementation detail currently limits the total number of small size + classes to 255, and a compilation error will result if the + you specify cannot be supported. The limit is + roughly =4, depending on page size. + +--with-lg-quantum= + Specify the base 2 log of the minimum allocation alignment. jemalloc needs + to know the minimum alignment that meets the following C standard + requirement (quoted from the April 12, 2011 draft of the C11 standard): + + The pointer returned if the allocation succeeds is suitably aligned so + that it may be assigned to a pointer to any type of object with a + fundamental alignment requirement and then used to access such an object + or an array of such objects in the space allocated [...] + + This setting is architecture-specific, and although jemalloc includes known + safe values for the most commonly used modern architectures, there is a + wrinkle related to GNU libc (glibc) that may impact your choice of + . On most modern architectures, this mandates 16-byte alignment + (=4), but the glibc developers chose not to meet this + requirement for performance reasons. An old discussion can be found at + https://sourceware.org/bugzilla/show_bug.cgi?id=206 . Unlike glibc, + jemalloc does follow the C standard by default (caveat: jemalloc + technically cheats if --with-lg-tiny-min is smaller than + --with-lg-quantum), but the fact that Linux systems already work around + this allocator noncompliance means that it is generally safe in practice to + let jemalloc's minimum alignment follow glibc's lead. If you specify + --with-lg-quantum=3 during configuration, jemalloc will provide additional + size classes that are not 16-byte-aligned (24, 40, and 56, assuming + --with-lg-size-class-group=2). + +--with-lg-tiny-min= + Specify the base 2 log of the minimum tiny size class to support. Tiny + size classes are powers of 2 less than the quantum, and are only + incorporated if is less than (see + --with-lg-quantum). Tiny size classes technically violate the C standard + requirement for minimum alignment, and crashes could conceivably result if + the compiler were to generate instructions that made alignment assumptions, + both because illegal instruction traps could result, and because accesses + could straddle page boundaries and cause segmentation faults due to + accessing unmapped addresses. + + The default of =3 works well in practice even on architectures + that technically require 16-byte alignment, probably for the same reason + --with-lg-quantum=3 works. Smaller tiny size classes can, and will, cause + crashes (see https://bugzilla.mozilla.org/show_bug.cgi?id=691003 for an + example). + + This option is rarely useful, and is mainly provided as documentation of a + subtle implementation detail. If you do use this option, specify a + value in [3, ..., ]. + +The following environment variables (not a definitive list) impact configure's +behavior: + +CFLAGS="?" + Pass these flags to the compiler. You probably shouldn't define this unless + you know what you are doing. (Use EXTRA_CFLAGS instead.) + +EXTRA_CFLAGS="?" + Append these flags to CFLAGS. This makes it possible to add flags such as + -Werror, while allowing the configure script to determine what other flags + are appropriate for the specified configuration. + + The configure script specifically checks whether an optimization flag (-O*) + is specified in EXTRA_CFLAGS, and refrains from specifying an optimization + level if it finds that one has already been specified. + +CPPFLAGS="?" + Pass these flags to the C preprocessor. Note that CFLAGS is not passed to + 'cpp' when 'configure' is looking for include files, so you must use + CPPFLAGS instead if you need to help 'configure' find header files. + +LD_LIBRARY_PATH="?" + 'ld' uses this colon-separated list to find libraries. + +LDFLAGS="?" + Pass these flags when linking. + +PATH="?" + 'configure' uses this to find programs. + +=== Advanced compilation ======================================================= + +To build only parts of jemalloc, use the following targets: + + build_lib_shared + build_lib_static + build_lib + build_doc_html + build_doc_man + build_doc + +To install only parts of jemalloc, use the following targets: + + install_bin + install_include + install_lib_shared + install_lib_static + install_lib + install_doc_html + install_doc_man + install_doc + +To clean up build results to varying degrees, use the following make targets: + + clean + distclean + relclean + +=== Advanced installation ====================================================== + +Optionally, define make variables when invoking make, including (not +exclusively): + +INCLUDEDIR="?" + Use this as the installation prefix for header files. + +LIBDIR="?" + Use this as the installation prefix for libraries. + +MANDIR="?" + Use this as the installation prefix for man pages. + +DESTDIR="?" + Prepend DESTDIR to INCLUDEDIR, LIBDIR, DATADIR, and MANDIR. This is useful + when installing to a different path than was specified via --prefix. + +CC="?" + Use this to invoke the C compiler. + +CFLAGS="?" + Pass these flags to the compiler. + +CPPFLAGS="?" + Pass these flags to the C preprocessor. + +LDFLAGS="?" + Pass these flags when linking. + +PATH="?" + Use this to search for programs used during configuration and building. + +=== Development ================================================================ + +If you intend to make non-trivial changes to jemalloc, use the 'autogen.sh' +script rather than 'configure'. This re-generates 'configure', enables +configuration dependency rules, and enables re-generation of automatically +generated source files. + +The build system supports using an object directory separate from the source +tree.

implementation that emphasizes +fragmentation avoidance and scalable concurrency support. jemalloc first came +into use as the FreeBSD libc allocator in 2005, and since then it has found its +way into numerous applications that rely on its predictable behavior. In 2010 +jemalloc development efforts broadened to include developer support features +such as heap profiling, Valgrind integration, and extensive monitoring/tuning +hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, +and therefore versatility remains critical. Ongoing development efforts trend +toward making jemalloc among the best allocators for a broad range of demanding +applications, and eliminating/mitigating weaknesses that have practical +repercussions for real world applications. + +The COPYING file contains copyright and licensing information. + +The INSTALL file contains information on how to configure, build, and install +jemalloc. + +The ChangeLog file contains a brief summary of changes for each release. + +URL: http://www.canonware.com/jemalloc/ diff --git a/src/third_party/jemalloc-4.2.1/SConscript b/src/third_party/jemalloc-4.2.1/SConscript new file mode 100644 index 0000000..b0cbc9e --- /dev/null +++ b/src/third_party/jemalloc-4.2.1/SConscript @@ -0,0 +1,63 @@ +# -*- mode: python -*- + +Import("env") +Import("debugBuild") + +env = env.Clone() +files = [ + 'src/arena.c', + 'src/atomic.c', + 'src/base.c', + 'src/bitmap.c', + 'src/chunk.c', + 'src/chunk_dss.c', + 'src/chunk_mmap.c', + 'src/ckh.c', + 'src/ctl.c', + 'src/extent.c', + 'src/hash.c', + 'src/huge.c', + 'src/jemalloc.c', + 'src/mb.c', + 'src/mutex.c', + 'src/nstime.c', + 'src/pages.c', + 'src/prng.c', + 'src/prof.c', + 'src/quarantine.c', + 'src/rtree.c', + 'src/stats.c', + 'src/tcache.c', + 'src/ticker.c', + 'src/tsd.c', + 'src/util.c', + 'src/witness.c' + ] + +if env.TargetOSIs('osx'): + files += [ + 'src/zone.c' + ] +elif env.TargetOSIs('linux'): + env.Append(CPPDEFINES=["_GNU_SOURCE"]) + +if debugBuild: + env.Append( CPPDEFINES=["JEMALLOC_DEBUG"] ) + +# Stolen from gperftools SConscript file. +env.Prepend( CPPPATH=["include/"] ) + +def removeIfPresent(lst, item): + try: + lst.remove(item) + except ValueError: + pass + +# JEMalloc uses the 'asm' symbol which isn't defined in c99 +for to_remove in ['-std=c99']: + removeIfPresent(env['CFLAGS'], to_remove) + +env.Library( + target='jemalloc', + source=files, +) diff --git a/src/third_party/jemalloc-4.2.1/VERSION b/src/third_party/jemalloc-4.2.1/VERSION new file mode 100644 index 0000000..b9e96ed --- /dev/null +++ b/src/third_party/jemalloc-4.2.1/VERSION @@ -0,0 +1 @@ +0.9.1-32198-g00974fcdfbb95cf5c0d5e0aacfba87f5e2620c24 diff --git a/src/third_party/jemalloc-4.2.1/autogen.sh b/src/third_party/jemalloc-4.2.1/autogen.sh new file mode 100755 index 0000000..75f32da --- /dev/null +++ b/src/third_party/jemalloc-4.2.1/autogen.sh @@ -0,0 +1,17 @@ +#!/bin/sh + +for i in autoconf;

The allocated space is suitably aligned (after possible pointer coercion) for storage of any type of object\&. +.PP +The +\fBcalloc\fR\fB\fR +function allocates space for +\fInumber\fR +objects, each +\fIsize\fR +bytes in length\&. The result is identical to calling +\fBmalloc\fR\fB\fR +with an argument of +\fInumber\fR +* +\fIsize\fR, with the exception that the allocated memory is explicitly initialized to zero bytes\&. +.PP +The +\fBposix_memalign\fR\fB\fR +function allocates +\fIsize\fR +bytes of memory such that the allocation\*(Aqs base address is a multiple of +\fIalignment\fR, and returns the allocation in the value pointed to by +\fIptr\fR\&. The requested +\fIalignment\fR +must be a power of 2 at least as large as +sizeof(\fBvoid *\fR)\&. +.PP +The +\fBaligned_alloc\fR\fB\fR +function allocates +\fIsize\fR +bytes of memory such that the allocation\*(Aqs base address is a multiple of +\fIalignment\fR\&. The requested +\fIalignment\fR +must be a power of 2\&. Behavior is undefined if +\fIsize\fR +is not an integral multiple of +\fIalignment\fR\&. +.PP +The +\fBrealloc\fR\fB\fR +function changes the size of the previously allocated memory referenced by +\fIptr\fR +to +\fIsize\fR +bytes\&. The contents of the memory are unchanged up to the lesser of the new and old sizes\&. If the new size is larger, the contents of the newly allocated portion of the memory are undefined\&. Upon success, the memory referenced by +\fIptr\fR +is freed and a pointer to the newly allocated memory is returned\&. Note that +\fBrealloc\fR\fB\fR +may move the memory allocation, resulting in a different return value than +\fIptr\fR\&. If +\fIptr\fR +is +\fBNULL\fR, the +\fBrealloc\fR\fB\fR +function behaves identically to +\fBmalloc\fR\fB\fR +for the specified size\&. +.PP +The +\fBfree\fR\fB\fR +function causes the allocated memory referenced by +\fIptr\fR +to be made available for future allocations\&. If +\fIptr\fR +is +\fBNULL\fR, no action occurs\&. +.SS "Non\-standard API" +.PP +The +\fBmallocx\fR\fB\fR, +\fBrallocx\fR\fB\fR, +\fBxallocx\fR\fB\fR, +\fBsallocx\fR\fB\fR, +\fBdallocx\fR\fB\fR, +\fBsdallocx\fR\fB\fR, and +\fBnallocx\fR\fB\fR +functions all have a +\fIflags\fR +argument that can be used to specify options\&. The functions only check the options that are contextually relevant\&. Use bitwise or (|) operations to specify one or more of the following: +.PP +\fBMALLOCX_LG_ALIGN(\fR\fB\fIla\fR\fR\fB) \fR +.RS 4 +Align the memory allocation to start at an address that is a multiple of +(1 << \fIla\fR)\&. This macro does not validate that +\fIla\fR +is within the valid range\&. +.RE +.PP +\fBMALLOCX_ALIGN(\fR\fB\fIa\fR\fR\fB) \fR +.RS 4 +Align the memory allocation to start at an address that is a multiple of +\fIa\fR, where +\fIa\fR +is a power of two\&. This macro does not validate that +\fIa\fR +is a power of 2\&. +.RE +.PP +\fBMALLOCX_ZERO\fR +.RS 4 +Initialize newly allocated memory to contain zero bytes\&. In the growing reallocation case, the real size prior to reallocation defines the boundary between untouched bytes and those that are initialized to contain zero bytes\&. If this macro is absent, newly allocated memory is uninitialized\&. +.RE +.PP +\fBMALLOCX_TCACHE(\fR\fB\fItc\fR\fR\fB) \fR +.RS 4 +Use the thread\-specific cache (tcache) specified by the identifier +\fItc\fR, which must have been acquired via the +"tcache\&.create" +mallctl\&. This macro does not validate that +\fItc\fR +specifies a valid identifier\&. +.RE +.PP +\fBMALLOCX_TCACHE_NONE\fR +.RS 4 +Do not use a thread\-specific cache (tcache)\&. Unless +\fBMALLOCX_TCACHE(\fR\fB\fItc\fR\fR\fB)\fR +or +\fBMALLOCX_TCACHE_NONE\fR +is specified, an automatically managed tcache will be used under many circumstances\&. This macro cannot be used in the same +\fIflags\fR +argument as +\fBMALLOCX_TCACHE(\fR\fB\fItc\fR\fR\fB)\fR\&. +.RE +.PP +\fBMALLOCX_ARENA(\fR\fB\fIa\fR\fR\fB) \fR +.RS 4 +Use the arena specified by the index +\fIa\fR\&. This macro has no effect for regions that were allocated via an arena other than the one specified\&. This macro does not validate that +\fIa\fR +specifies an arena index in the valid range\&. +.RE +.PP +The +\fBmallocx\fR\fB\fR +function allocates at least +\fIsize\fR +bytes of memory, and returns a pointer to the base address of the allocation\&. Behavior is undefined if +\fIsize\fR +is +\fB0\fR\&. +.PP +The +\fBrallocx\fR\fB\fR +function resizes the allocation at +\fIptr\fR +to be at least +\fIsize\fR +bytes, and returns a pointer to the base address of the resulting allocation, which may or may not have moved from its original location\&. Behavior is undefined if +\fIsize\fR +is +\fB0\fR\&. +.PP +The +\fBxallocx\fR\fB\fR +function resizes the allocation at +\fIptr\fR +in place to be at least +\fIsize\fR +bytes, and returns the real size of the allocation\&. If +\fIextra\fR +is non\-zero, an attempt is made to resize the allocation to be at least +(\fIsize\fR + \fIextra\fR) +bytes, though inability to allocate the extra byte(s) will not by itself result in failure to resize\&. Behavior is undefined if +\fIsize\fR +is +\fB0\fR, or if +(\fIsize\fR + \fIextra\fR > \fBSIZE_T_MAX\fR)\&. +.PP +The +\fBsallocx\fR\fB\fR +function returns the real size of the allocation at +\fIptr\fR\&. +.PP +The +\fBdallocx\fR\fB\fR +function causes the memory referenced by +\fIptr\fR +to be made available for future allocations\&. +.PP +The +\fBsdallocx\fR\fB\fR +function is an extension of +\fBdallocx\fR\fB\fR +with a +\fIsize\fR +parameter to allow the caller to pass in the allocation size as an optimization\&. The minimum valid input size is the original requested size of the allocation, and the maximum valid input size is the corresponding value returned by +\fBnallocx\fR\fB\fR +or +\fBsallocx\fR\fB\fR\&. +.PP +The +\fBnallocx\fR\fB\fR +function allocates no memory, but it performs the same size computation as the +\fBmallocx\fR\fB\fR +function, and returns the real size of the allocation that would result from the equivalent +\fBmallocx\fR\fB\fR +function call, or +\fB0\fR +if the inputs exceed the maximum supported size class and/or alignment\&. Behavior is undefined if +\fIsize\fR +is +\fB0\fR\&. +.PP +The +\fBmallctl\fR\fB\fR +function provides a general interface for introspecting the memory allocator, as well as setting modifiable parameters and triggering actions\&. The period\-separated +\fIname\fR +argument specifies a location in a tree\-structured namespace; see the +MALLCTL NAMESPACE +section for documentation on the tree contents\&. To read a value, pass a pointer via +\fIoldp\fR +to adequate space to contain the value, and a pointer to its length via +\fIoldlenp\fR; otherwise pass +\fBNULL\fR +and +\fBNULL\fR\&. Similarly, to write a value, pass a pointer to the value via +\fInewp\fR, and its length via +\fInewlen\fR; otherwise pass +\fBNULL\fR +and +\fB0\fR\&. +.PP +The +\fBmallctlnametomib\fR\fB\fR +function provides a way to avoid repeated name lookups for applications that repeatedly query the same portion of the namespace, by translating a name to a \(lqManagement Information Base\(rq (MIB) that can be passed repeatedly to +\fBmallctlbymib\fR\fB\fR\&. Upon successful return from +\fBmallctlnametomib\fR\fB\fR, +\fImibp\fR +contains an array of +\fI*miblenp\fR +integers, where +\fI*miblenp\fR +is the lesser of the number of components in +\fIname\fR +and the input value of +\fI*miblenp\fR\&. Thus it is possible to pass a +\fI*miblenp\fR +that is smaller than the number of period\-separated name components, which results in a partial MIB that can be used as the basis for constructing a complete MIB\&. For name components that are integers (e\&.g\&. the 2 in +"arenas\&.bin\&.2\&.size"), the corresponding MIB component will always be that integer\&. Therefore, it is legitimate to construct code like the following: +.sp +.if n \{\ +.RS 4 +.\} +.nf +unsigned nbins, i; +size_t mib[4]; +size_t len, miblen; + +len = sizeof(nbins); +mallctl("arenas\&.nbins", &nbins, &len, NULL, 0); + +miblen = 4; +mallctlnametomib("arenas\&.bin\&.0\&.size", mib, &miblen); +for (i = 0; i < nbins; i++) { + size_t bin_size; + + mib[2] = i; + len = sizeof(bin_size); + mallctlbymib(mib, miblen, &bin_size, &len, NULL, 0); + /* Do something with bin_size\&.\&.\&. */ +} +.fi +.if n \{\ +.RE +.\} +.PP +The +\fBmalloc_stats_print\fR\fB\fR +function writes human\-readable summary statistics via the +\fIwrite_cb\fR +callback function pointer and +\fIcbopaque\fR +data passed to +\fIwrite_cb\fR, or +\fBmalloc_message\fR\fB\fR +if +\fIwrite_cb\fR +is +\fBNULL\fR\&. This function can be called repeatedly\&. General information that never changes during execution can be omitted by specifying "g" as a character within the +\fIopts\fR +string\&. Note that +\fBmalloc_message\fR\fB\fR +uses the +\fBmallctl*\fR\fB\fR +functions internally, so inconsistent statistics can be reported if multiple threads use these functions simultaneously\&. If +\fB\-\-enable\-stats\fR +is specified during configuration, \(lqm\(rq and \(lqa\(rq can be specified to omit merged arena and per arena statistics, respectively; \(lqb\(rq, \(lql\(rq, and \(lqh\(rq can be specified to omit per size class statistics for bins, large objects, and huge objects, respectively\&. Unrecognized characters are silently ignored\&. Note that thread caching may prevent some statistics from being completely up to date, since extra locking would be required to merge counters that track thread cache operations\&. +.PP +The +\fBmalloc_usable_size\fR\fB\fR +function returns the usable size of the allocation pointed to by +\fIptr\fR\&. The return value may be larger than the size that was requested during allocation\&. The +\fBmalloc_usable_size\fR\fB\fR +function is not a mechanism for in\-place +\fBrealloc\fR\fB\fR; rather it is provided solely as a tool for introspection purposes\&. Any discrepancy between the requested allocation size and the size reported by +\fBmalloc_usable_size\fR\fB\fR +should not be depended on, since such behavior is entirely implementation\-dependent\&. +.SH "TUNING" +.PP +Once, when the first call is made to one of the memory allocation routines, the allocator initializes its internals based in part on various options that can be specified at compile\- or run\-time\&. +.PP +The string specified via +\fB\-\-with\-malloc\-conf\fR, the string pointed to by the global variable +\fImalloc_conf\fR, the \(lqname\(rq of the file referenced by the symbolic link named +/etc/malloc\&.conf, and the value of the environment variable +\fBMALLOC_CONF\fR, will be interpreted, in that order, from left to right as options\&. Note that +\fImalloc_conf\fR +may be read before +\fBmain\fR\fB\fR +is entered, so the declaration of +\fImalloc_conf\fR +should specify an initializer that contains the final value to be read by jemalloc\&. +\fB\-\-with\-malloc\-conf\fR +and +\fImalloc_conf\fR +are compile\-time mechanisms, whereas +/etc/malloc\&.conf +and +\fBMALLOC_CONF\fR +can be safely set any time prior to program invocation\&. +.PP +An options string is a comma\-separated list of option:value pairs\&. There is one key corresponding to each +"opt\&.*" +mallctl (see the +MALLCTL NAMESPACE +section for options documentation)\&. For example, +abort:true,narenas:1 +sets the +"opt\&.abort" +and +"opt\&.narenas" +options\&. Some options have boolean values (true/false), others have integer values (base 8, 10, or 16, depending on prefix), and yet others have raw string values\&. +.SH "IMPLEMENTATION NOTES" +.PP +Traditionally, allocators have used +\fBsbrk\fR(2) +to obtain memory, which is suboptimal for several reasons, including race conditions, increased fragmentation, and artificial limitations on maximum usable memory\&. If +\fBsbrk\fR(2) +is supported by the operating system, this allocator uses both +\fBmmap\fR(2) +and +\fBsbrk\fR(2), in that order of preference; otherwise only +\fBmmap\fR(2) +is used\&. +.PP +This allocator uses multiple arenas in order to reduce lock contention for threaded programs on multi\-processor systems\&. This works well with regard to threading scalability, but incurs some costs\&. There is a small fixed per\-arena overhead, and additionally, arenas manage memory completely independently of each other, which means a small fixed increase in overall memory fragmentation\&. These overheads are not generally an issue, given the number of arenas normally used\&. Note that using substantially more arenas than the default is not likely to improve performance, mainly due to reduced cache performance\&. However, it may make sense to reduce the number of arenas if an application does not make much use of the allocation functions\&. +.PP +In addition to multiple arenas, unless +\fB\-\-disable\-tcache\fR +is specified during configuration, this allocator supports thread\-specific caching for small and large objects, in order to make it possible to completely avoid synchronization for most allocation requests\&. Such caching allows very fast allocation in the common case, but it increases memory usage and fragmentation, since a bounded number of objects can remain allocated in each thread cache\&. +.PP +Memory is conceptually broken into equal\-sized chunks, where the chunk size is a power of two that is greater than the page size\&. Chunks are always aligned to multiples of the chunk size\&. This alignment makes it possible to find metadata for user objects very quickly\&. User objects are broken into three categories according to size: small, large, and huge\&. Multiple small and large objects can reside within a single chunk, whereas huge objects each have one or more chunks backing them\&. Each chunk that contains small and/or large objects tracks its contents as runs of contiguous pages (unused, backing a set of small objects, or backing one large object)\&. The combination of chunk alignment and chunk page maps makes it possible to determine all metadata regarding small and large allocations in constant time\&. +.PP +Small objects are managed in groups by page runs\&. Each run maintains a bitmap to track which regions are in use\&. Allocation requests that are no more than half the quantum (8 or 16, depending on architecture) are rounded up to the nearest power of two that is at least +sizeof(\fBdouble\fR)\&. All other object size classes are multiples of the quantum, spaced such that there are four size classes for each doubling in size, which limits internal fragmentation to approximately 20% for all but the smallest size classes\&. Small size classes are smaller than four times the page size, large size classes are smaller than the chunk size (see the +"opt\&.lg_chunk" +option), and huge size classes extend from the chunk size up to the largest size class that does not exceed +\fBPTRDIFF_MAX\fR\&. +.PP +Allocations are packed tightly together, which can be an issue for multi\-threaded applications\&. If you need to assure that allocations do not suffer from cacheline sharing, round your allocation requests up to the nearest multiple of the cacheline size, or specify cacheline alignment when allocating\&. +.PP +The +\fBrealloc\fR\fB\fR, +\fBrallocx\fR\fB\fR, and +\fBxallocx\fR\fB\fR +functions may resize allocations without moving them under limited circumstances\&. Unlike the +\fB*allocx\fR\fB\fR +API, the standard API does not officially round up the usable size of an allocation to the nearest size class, so technically it is necessary to call +\fBrealloc\fR\fB\fR +to grow e\&.g\&. a 9\-byte allocation to 16 bytes, or shrink a 16\-byte allocation to 9 bytes\&. Growth and shrinkage trivially succeeds in place as long as the pre\-size and post\-size both round up to the same size class\&.

DESCRIPTION

Standard API

The malloc() function allocates + size bytes of uninitialized memory. The allocated + space is suitably aligned (after possible pointer coercion) for storage + of any type of object.

The calloc() function allocates + space for number objects, each + size bytes in length. The result is identical to + calling malloc() with an argument of + number * size, with the + exception that the allocated memory is explicitly initialized to zero + bytes.

The posix_memalign() function + allocates size bytes of memory such that the + allocation's base address is a multiple of + alignment, and returns the allocation in the value + pointed to by ptr. The requested + alignment must be a power of 2 at least as large as + sizeof(void *).

The aligned_alloc() function + allocates size bytes of memory such that the + allocation's base address is a multiple of + alignment. The requested + alignment must be a power of 2. Behavior is + undefined if size is not an integral multiple of + alignment.

The realloc() function changes the + size of the previously allocated memory referenced by + ptr to size bytes. The + contents of the memory are unchanged up to the lesser of the new and old + sizes. If the new size is larger, the contents of the newly allocated + portion of the memory are undefined. Upon success, the memory referenced + by ptr is freed and a pointer to the newly + allocated memory is returned. Note that + realloc() may move the memory allocation, + resulting in a different return value than ptr. + If ptr is NULL, the + realloc() function behaves identically to + malloc() for the specified size.

The free() function causes the + allocated memory referenced by ptr to be made + available for future allocations. If ptr is + NULL, no action occurs.

Non-standard API

The mallocx(), + rallocx(), + xallocx(), + sallocx(), + dallocx(), + sdallocx(), and + nallocx() functions all have a + flags argument that can be used to specify + options. The functions only check the options that are contextually + relevant. Use bitwise or (|) operations to + specify one or more of the following: +

MALLOCX_LG_ALIGN(la) +

Align the memory allocation to start at an address + that is a multiple of (1 << + la). This macro does not validate + that la is within the valid + range.

MALLOCX_ALIGN(a) +

Align the memory allocation to start at an address + that is a multiple of a, where + a is a power of two. This macro does not + validate that a is a power of 2. +

MALLOCX_ZERO

Initialize newly allocated memory to contain zero + bytes. In the growing reallocation case, the real size prior to + reallocation defines the boundary between untouched bytes and those + that are initialized to contain zero bytes. If this macro is + absent, newly allocated memory is uninitialized.

MALLOCX_TCACHE(tc) +

Use the thread-specific cache (tcache) specified by + the identifier tc, which must have been + acquired via the + "tcache.create" + + mallctl. This macro does not validate that + tc specifies a valid + identifier.

MALLOCX_TCACHE_NONE

Do not use a thread-specific cache (tcache). Unless + MALLOCX_TCACHE(tc) or + MALLOCX_TCACHE_NONE is specified, an + automatically managed tcache will be used under many circumstances. + This macro cannot be used in the same flags + argument as + MALLOCX_TCACHE(tc).

MALLOCX_ARENA(a) +

Use the arena specified by the index + a. This macro has no effect for regions that + were allocated via an arena other than the one specified. This + macro does not validate that a specifies an + arena index in the valid range.

+

The mallocx() function allocates at + least size bytes of memory, and returns a pointer + to the base address of the allocation. Behavior is undefined if + size is 0.

The rallocx() function resizes the + allocation at ptr to be at least + size bytes, and returns a pointer to the base + address of the resulting allocation, which may or may not have moved from + its original location. Behavior is undefined if + size is 0.

The xallocx() function resizes the + allocation at ptr in place to be at least + size bytes, and returns the real size of the + allocation. If extra is non-zero, an attempt is + made to resize the allocation to be at least (size + + extra) bytes, though inability to allocate + the extra byte(s) will not by itself result in failure to resize. + Behavior is undefined if size is + 0, or if (size + extra + > SIZE_T_MAX).

The sallocx() function returns the + real size of the allocation at ptr.

The dallocx() function causes the + memory referenced by ptr to be made available for + future allocations.

The sdallocx() function is an + extension of dallocx() with a + size parameter to allow the caller to pass in the + allocation size as an optimization. The minimum valid input size is the + original requested size of the allocation, and the maximum valid input + size is the corresponding value returned by + nallocx() or + sallocx().

The nallocx() function allocates no + memory, but it performs the same size computation as the + mallocx() function, and returns the real + size of the allocation that would result from the equivalent + mallocx() function call, or + 0 if the inputs exceed the maximum supported size + class and/or alignment. Behavior is undefined if + size is 0.

The mallctl() function provides a + general interface for introspecting the memory allocator, as well as + setting modifiable parameters and triggering actions. The + period-separated name argument specifies a + location in a tree-structured namespace; see the MALLCTL NAMESPACE section for + documentation on the tree contents. To read a value, pass a pointer via + oldp to adequate space to contain the value, and a + pointer to its length via oldlenp; otherwise pass + NULL and NULL. Similarly, to + write a value, pass a pointer to the value via + newp, and its length via + newlen; otherwise pass NULL + and 0.

The mallctlnametomib() function + provides a way to avoid repeated name lookups for applications that + repeatedly query the same portion of the namespace, by translating a name + to a “Management Information Base” (MIB) that can be passed + repeatedly to mallctlbymib(). Upon + successful return from mallctlnametomib(), + mibp contains an array of + *miblenp integers, where + *miblenp is the lesser of the number of components + in name and the input value of + *miblenp. Thus it is possible to pass a + *miblenp that is smaller than the number of + period-separated name components, which results in a partial MIB that can + be used as the basis for constructing a complete MIB. For name + components that are integers (e.g. the 2 in + + "arenas.bin.2.size" + ), + the corresponding MIB component will always be that integer. Therefore, + it is legitimate to construct code like the following: 

+unsigned nbins, i;
+size_t mib[4];
+size_t len, miblen;
+
+len = sizeof(nbins);
+mallctl("arenas.nbins", &nbins, &len, NULL, 0);
+
+miblen = 4;
+mallctlnametomib("arenas.bin.0.size", mib, &miblen);
+for (i = 0; i < nbins; i++) {
+	size_t bin_size;
+
+	mib[2] = i;
+	len = sizeof(bin_size);
+	mallctlbymib(mib, miblen, &bin_size, &len, NULL, 0);
+	/* Do something with bin_size... */
+}

The malloc_stats_print() function + writes human-readable summary statistics via the + write_cb callback function pointer and + cbopaque data passed to + write_cb, or + malloc_message() if + write_cb is NULL. This + function can be called repeatedly. General information that never + changes during execution can be omitted by specifying "g" as a character + within the opts string. Note that + malloc_message() uses the + mallctl*() functions internally, so + inconsistent statistics can be reported if multiple threads use these + functions simultaneously. If --enable-stats is + specified during configuration, “m” and “a” can + be specified to omit merged arena and per arena statistics, respectively; + “b”, “l”, and “h” can be specified to + omit per size class statistics for bins, large objects, and huge objects, + respectively. Unrecognized characters are silently ignored. Note that + thread caching may prevent some statistics from being completely up to + date, since extra locking would be required to merge counters that track + thread cache operations. +

The malloc_usable_size() function + returns the usable size of the allocation pointed to by + ptr. The return value may be larger than the size + that was requested during allocation. The + malloc_usable_size() function is not a + mechanism for in-place realloc(); rather + it is provided solely as a tool for introspection purposes. Any + discrepancy between the requested allocation size and the size reported + by malloc_usable_size() should not be + depended on, since such behavior is entirely implementation-dependent. +

TUNING

Once, when the first call is made to one of the memory allocation + routines, the allocator initializes its internals based in part on various + options that can be specified at compile- or run-time.

The string specified via --with-malloc-conf, the + string pointed to by the global variable malloc_conf, the + “name” of the file referenced by the symbolic link named + /etc/malloc.conf, and the value of the + environment variable MALLOC_CONF, will be interpreted, in + that order, from left to right as options. Note that + malloc_conf may be read before + main() is entered, so the declaration of + malloc_conf should specify an initializer that contains + the final value to be read by jemalloc. --with-malloc-conf + and malloc_conf are compile-time mechanisms, whereas + /etc/malloc.conf and + MALLOC_CONF can be safely set any time prior to program + invocation.

An options string is a comma-separated list of option:value pairs. + There is one key corresponding to each + "opt.*" + mallctl (see the MALLCTL NAMESPACE section for options + documentation). For example, abort:true,narenas:1 sets + the + "opt.abort" + and + "opt.narenas" + options. Some + options have boolean values (true/false), others have integer values (base + 8, 10, or 16, depending on prefix), and yet others have raw string + values.

IMPLEMENTATION NOTES

Traditionally, allocators have used + sbrk(2) to obtain memory, which is + suboptimal for several reasons, including race conditions, increased + fragmentation, and artificial limitations on maximum usable memory. If + sbrk(2) is supported by the operating + system, this allocator uses both + mmap(2) and + sbrk(2), in that order of preference; + otherwise only mmap(2) is used.

This allocator uses multiple arenas in order to reduce lock + contention for threaded programs on multi-processor systems. This works + well with regard to threading scalability, but incurs some costs. There is + a small fixed per-arena overhead, and additionally, arenas manage memory + completely independently of each other, which means a small fixed increase + in overall memory fragmentation. These overheads are not generally an + issue, given the number of arenas normally used. Note that using + substantially more arenas than the default is not likely to improve + performance, mainly due to reduced cache performance. However, it may make + sense to reduce the number of arenas if an application does not make much + use of the allocation functions.

In addition to multiple arenas, unless + --disable-tcache is specified during configuration, this + allocator supports thread-specific caching for small and large objects, in + order to make it possible to completely avoid synchronization for most + allocation requests. Such caching allows very fast allocation in the + common case, but it increases memory usage and fragmentation, since a + bounded number of objects can remain allocated in each thread cache.

Memory is conceptually broken into equal-sized chunks, where the chunk + size is a power of two that is greater than the page size. Chunks are + always aligned to multiples of the chunk size. This alignment makes it + possible to find metadata for user objects very quickly. User objects are + broken into three categories according to size: small, large, and huge. + Multiple small and large objects can reside within a single chunk, whereas + huge objects each have one or more chunks backing them. Each chunk that + contains small and/or large objects tracks its contents as runs of + contiguous pages (unused, backing a set of small objects, or backing one + large object). The combination of chunk alignment and chunk page maps makes + it possible to determine all metadata regarding small and large allocations + in constant time.

Small objects are managed in groups by page runs. Each run maintains + a bitmap to track which regions are in use. Allocation requests that are no + more than half the quantum (8 or 16, depending on architecture) are rounded + up to the nearest power of two that is at least sizeof(double). All other object size + classes are multiples of the quantum, spaced such that there are four size + classes for each doubling in size, which limits internal fragmentation to + approximately 20% for all but the smallest size classes. Small size classes + are smaller than four times the page size, large size classes are smaller + than the chunk size (see the + "opt.lg_chunk" + option), and + huge size classes extend from the chunk size up to the largest size class + that does not exceed PTRDIFF_MAX.

Allocations are packed tightly together, which can be an issue for + multi-threaded applications. If you need to assure that allocations do not + suffer from cacheline sharing, round your allocation requests up to the + nearest multiple of the cacheline size, or specify cacheline alignment when + allocating.

The realloc(), + rallocx(), and + xallocx() functions may resize allocations + without moving them under limited circumstances. Unlike the + *allocx() API, the standard API does not + officially round up the usable size of an allocation to the nearest size + class, so technically it is necessary to call + realloc() to grow e.g. a 9-byte allocation to + 16 bytes, or shrink a 16-byte allocation to 9 bytes. Growth and shrinkage + trivially succeeds in place as long as the pre-size and post-size both round + up to the same size class. No other API guarantees are made regarding + in-place resizing, but the current implementation also tries to resize large + and huge allocations in place, as long as the pre-size and post-size are + both large or both huge. In such cases shrinkage always succeeds for large + size classes, but for huge size classes the chunk allocator must support + splitting (see + "arena.<i>.chunk_hooks" + ). + Growth only succeeds if the trailing memory is currently available, and + additionally for huge size classes the chunk allocator must support + merging.

Assuming 2 MiB chunks, 4 KiB pages, and a 16-byte quantum on a + 64-bit system, the size classes in each category are as shown in Table 1.

MALLCTL NAMESPACE

The following names are defined in the namespace accessible via the + mallctl*() functions. Value types are + specified in parentheses, their readable/writable statuses are encoded as + rw, r-, -w, or + --, and required build configuration flags follow, if + any. A name element encoded as <i> or + <j> indicates an integer component, where the + integer varies from 0 to some upper value that must be determined via + introspection. In the case of + "stats.arenas.<i>.*" + , + <i> equal to + "arenas.narenas" + can be + used to access the summation of statistics from all arenas. Take special + note of the + "epoch" + mallctl, + which controls refreshing of cached dynamic statistics.

Return the jemalloc version string.

+ + "epoch" + + (uint64_t) + rw +

If a value is passed in, refresh the data from which + the mallctl*() functions report values, + and increment the epoch. Return the current epoch. This is useful for + detecting whether another thread caused a refresh.

+ + "config.xmalloc" + + (bool) + r- +

--enable-xmalloc was specified during + build configuration.

+ + "opt.abort" + + (bool) + r- +

Abort-on-warning enabled/disabled. If true, most + warnings are fatal. The process will call + abort(3) in these cases. This option is + disabled by default unless --enable-debug is + specified during configuration, in which case it is enabled by default. +

+ + "opt.dss" + + (const char *) + r- +

dss (sbrk(2)) allocation precedence as + related to mmap(2) allocation. The following + settings are supported if + sbrk(2) is supported by the operating + system: “disabled”, “primary”, and + “secondary”; otherwise only “disabled” is + supported. The default is “secondary” if + sbrk(2) is supported by the operating + system; “disabled” otherwise. +

+ + "opt.lg_chunk" + + (size_t) + r- +

Virtual memory chunk size (log base 2). If a chunk + size outside the supported size range is specified, the size is + silently clipped to the minimum/maximum supported size. The default + chunk size is 2 MiB (2^21). +

This + provides the kernel with sufficient information to recycle dirty pages + if physical memory becomes scarce and the pages remain unused. The + default minimum ratio is 8:1 (2^3:1); an option value of -1 will + disable dirty page purging. See + "arenas.lg_dirty_mult" + + and + "arena.<i>.lg_dirty_mult" + + for related dynamic control options.

+ + "opt.decay_time" + + (ssize_t) + r- +

Approximate time in seconds from the creation of a set + of unused dirty pages until an equivalent set of unused dirty pages is + purged and/or reused. The pages are incrementally purged according to a + sigmoidal decay curve that starts and ends with zero purge rate. A + decay time of 0 causes all unused dirty pages to be purged immediately + upon creation. A decay time of -1 disables purging. The default decay + time is 10 seconds. See + "arenas.decay_time" + + and + "arena.<i>.decay_time" + + for related dynamic control options. +

+ + "opt.stats_print" + + (bool) + r- +

Enable/disable statistics printing at exit. If + enabled, the malloc_stats_print() + function is called at program exit via an + atexit(3) function. If + --enable-stats is specified during configuration, this + has the potential to cause deadlock for a multi-threaded process that + exits while one or more threads are executing in the memory allocation + functions. Furthermore, atexit() may + allocate memory during application initialization and then deadlock + internally when jemalloc in turn calls + atexit(), so this option is not + universally usable (though the application can register its own + atexit() function with equivalent + functionality). Therefore, this option should only be used with care; + it is primarily intended as a performance tuning aid during application + development. This option is disabled by default.

+ + "opt.junk" + + (const char *) + r- + [--enable-fill] +

Junk filling. If set to "alloc", each byte of + uninitialized allocated memory will be initialized to + 0xa5. If set to "free", all deallocated memory will + be initialized to 0x5a. If set to "true", both + allocated and deallocated memory will be initialized, and if set to + "false", junk filling be disabled entirely. This is intended for + debugging and will impact performance negatively. This option is + "false" by default unless --enable-debug is specified + during configuration, in which case it is "true" by default unless + running inside Valgrind.

+ + "opt.quarantine" + + (size_t) + r- + [--enable-fill] +

Per thread quarantine size in bytes. If non-zero, each + thread maintains a FIFO object quarantine that stores up to the + specified number of bytes of memory. The quarantined memory is not + freed until it is released from quarantine, though it is immediately + junk-filled if the + "opt.junk" + option is + enabled. This feature is of particular use in combination with Valgrind, which can detect attempts + to access quarantined objects. This is intended for debugging and will + impact performance negatively. The default quarantine size is 0 unless + running inside Valgrind, in which case the default is 16 + MiB.

+ + "opt.redzone" + + (bool) + r- + [--enable-fill] +

Redzones enabled/disabled. If enabled, small + allocations have redzones before and after them. Furthermore, if the + + "opt.junk" + option is + enabled, the redzones are checked for corruption during deallocation. + However, the primary intended purpose of this feature is to be used in + combination with Valgrind, + which needs redzones in order to do effective buffer overflow/underflow + detection. This option is intended for debugging and will impact + performance negatively. This option is disabled by + default unless running inside Valgrind.

+ + "opt.zero" + + (bool) + r- + [--enable-fill] +

Zero filling enabled/disabled. If enabled, each byte + of uninitialized allocated memory will be initialized to 0. Note that + this initialization only happens once for each byte, so + realloc() and + rallocx() calls do not zero memory that + was previously allocated. This is intended for debugging and will + impact performance negatively. This option is disabled by default. +

+ + "opt.utrace" + + (bool) + r- + [--enable-utrace] +

Allocation tracing based on + utrace(2) enabled/disabled. This option + is disabled by default.

+ + "opt.xmalloc" + + (bool) + r- + [--enable-xmalloc] +

Abort-on-out-of-memory enabled/disabled. If enabled, + rather than returning failure for any allocation function, display a + diagnostic message on STDERR_FILENO and cause the + program to drop core (using + abort(3)). If an application is + designed to depend on this behavior, set the option at compile time by + including the following in the source code: + 

+malloc_conf = "xmalloc:true";

+ This option is disabled by default.

+ + "opt.tcache" + + (bool) + r- + [--enable-tcache] +

Thread-specific caching (tcache) enabled/disabled. When + there are multiple threads, each thread uses a tcache for objects up to + a certain size. Thread-specific caching allows many allocations to be + satisfied without performing any thread synchronization, at the cost of + increased memory use. See the + "opt.lg_tcache_max" + + option for related tuning information. This option is enabled by + default unless running inside Valgrind, in which case it is + forcefully disabled.

+ + "opt.lg_tcache_max" + + (size_t) + r- + [--enable-tcache] +

Maximum size class (log base 2) to cache in the + thread-specific cache (tcache). At a minimum, all small size classes + are cached, and at a maximum all large size classes are cached. The + default maximum is 32 KiB (2^15).

+ + "opt.prof" + + (bool) + r- + [--enable-prof] +

Memory profiling enabled/disabled. If enabled, profile + memory allocation activity. See the + "opt.prof_active" + + option for on-the-fly activation/deactivation. See the + "opt.lg_prof_sample" + + option for probabilistic sampling control. See the + "opt.prof_accum" + + option for control of cumulative sample reporting. See the + "opt.lg_prof_interval" + + option for information on interval-triggered profile dumping, the + "opt.prof_gdump" + + option for information on high-water-triggered profile dumping, and the + + "opt.prof_final" + + option for final profile dumping. Profile output is compatible with + the jeprof command, which is based on the + pprof that is developed as part of the gperftools + package. See HEAP PROFILE + FORMAT for heap profile format documentation.

+ + "opt.prof_prefix" + + (const char *) + r- + [--enable-prof] +

Filename prefix for profile dumps. If the prefix is + set to the empty string, no automatic dumps will occur; this is + primarily useful for disabling the automatic final heap dump (which + also disables leak reporting, if enabled). The default prefix is + jeprof.

+ + "opt.prof_active" + + (bool) + r- + [--enable-prof] +

Profiling activated/deactivated. This is a secondary + control mechanism that makes it possible to start the application with + profiling enabled (see the + "opt.prof" + option) but + inactive, then toggle profiling at any time during program execution + with the + "prof.active" + mallctl. + This option is enabled by default.

+ + "opt.prof_thread_active_init" + + (bool) + r- + [--enable-prof] +

Initial setting for + "thread.prof.active" + + in newly created threads. The initial setting for newly created threads + can also be changed during execution via the + "prof.thread_active_init" + + mallctl. This option is enabled by default.

+ + "opt.lg_prof_sample" + + (size_t) + r- + [--enable-prof] +

Average interval (log base 2) between allocation + samples, as measured in bytes of allocation activity. Increasing the + sampling interval decreases profile fidelity, but also decreases the + computational overhead. The default sample interval is 512 KiB (2^19 + B).

+ + "opt.prof_accum" + + (bool) + r- + [--enable-prof] +

Reporting of cumulative object/byte counts in profile + dumps enabled/disabled. If this option is enabled, every unique + backtrace must be stored for the duration of execution. Depending on + the application, this can impose a large memory overhead, and the + cumulative counts are not always of interest. This option is disabled + by default.

+ + "opt.lg_prof_interval" + + (ssize_t) + r- + [--enable-prof] +

Average interval (log base 2) between memory profile + dumps, as measured in bytes of allocation activity. The actual + interval between dumps may be sporadic because decentralized allocation + counters are used to avoid synchronization bottlenecks. Profiles are + dumped to files named according to the pattern + <prefix>.<pid>.<seq>.i<iseq>.heap, + where <prefix> is controlled by the + + "opt.prof_prefix" + + option. By default, interval-triggered profile dumping is disabled + (encoded as -1). +

+ + "opt.prof_gdump" + + (bool) + r- + [--enable-prof] +

Set the initial state of + "prof.gdump" + , which when + enabled triggers a memory profile dump every time the total virtual + memory exceeds the previous maximum. This option is disabled by + default.

+ + "opt.prof_final" + + (bool) + r- + [--enable-prof] +

Use an + atexit(3) function to dump final memory + usage to a file named according to the pattern + <prefix>.<pid>.<seq>.f.heap, + where <prefix> is controlled by the + "opt.prof_prefix" + + option. Note that atexit() may allocate + memory during application initialization and then deadlock internally + when jemalloc in turn calls atexit(), so + this option is not universally usable (though the application can + register its own atexit() function with + equivalent functionality). This option is disabled by + default.

+ + "opt.prof_leak" + + (bool) + r- + [--enable-prof] +

Leak reporting enabled/disabled. If enabled, use an + atexit(3) function to report memory leaks + detected by allocation sampling. See the + + "opt.prof" + option for + information on analyzing heap profile output. This option is disabled + by default.

+ + "thread.arena" + + (unsigned) + rw +

Get or set the arena associated with the calling + thread. If the specified arena was not initialized beforehand (see the + + "arenas.initialized" + + mallctl), it will be automatically initialized as a side effect of + calling this interface.

+ + "thread.allocated" + + (uint64_t) + r- + [--enable-stats] +

Get the total number of bytes ever allocated by the + calling thread. This counter has the potential to wrap around; it is + up to the application to appropriately interpret the counter in such + cases.

+ + "thread.allocatedp" + + (uint64_t *) + r- + [--enable-stats] +

Get a pointer to the the value that is returned by the + + "thread.allocated" + + mallctl. This is useful for avoiding the overhead of repeated + mallctl*() calls.

+ + "thread.deallocated" + + (uint64_t) + r- + [--enable-stats] +

Get the total number of bytes ever deallocated by the + calling thread. This counter has the potential to wrap around; it is + up to the application to appropriately interpret the counter in such + cases.

+ + "thread.deallocatedp" + + (uint64_t *) + r- + [--enable-stats] +

Get a pointer to the the value that is returned by the + + "thread.deallocated" + + mallctl. This is useful for avoiding the overhead of repeated + mallctl*() calls.

+ + "thread.tcache.enabled" + + (bool) + rw + [--enable-tcache] +

Enable/disable calling thread's tcache. The tcache is + implicitly flushed as a side effect of becoming + disabled (see + "thread.tcache.flush" + ). +

+ + "thread.tcache.flush" + + (void) + -- + [--enable-tcache] +

Flush calling thread's thread-specific cache (tcache). + This interface releases all cached objects and internal data structures + associated with the calling thread's tcache. Ordinarily, this interface + need not be called, since automatic periodic incremental garbage + collection occurs, and the thread cache is automatically discarded when + a thread exits. However, garbage collection is triggered by allocation + activity, so it is possible for a thread that stops + allocating/deallocating to retain its cache indefinitely, in which case + the developer may find manual flushing useful.

+ + "thread.prof.name" + + (const char *) + r- or + -w + [--enable-prof] +

Get/set the descriptive name associated with the calling + thread in memory profile dumps. An internal copy of the name string is + created, so the input string need not be maintained after this interface + completes execution. The output string of this interface should be + copied for non-ephemeral uses, because multiple implementation details + can cause asynchronous string deallocation. Furthermore, each + invocation of this interface can only read or write; simultaneous + read/write is not supported due to string lifetime limitations. The + name string must be nil-terminated and comprised only of characters in + the sets recognized + by isgraph(3) and + isblank(3).

+ + "thread.prof.active" + + (bool) + rw + [--enable-prof] +

Control whether sampling is currently active for the + calling thread. This is an activation mechanism in addition to + "prof.active" + ; both must + be active for the calling thread to sample. This flag is enabled by + default.

+ + "tcache.create" + + (unsigned) + r- + [--enable-tcache] +

Create an explicit thread-specific cache (tcache) and + return an identifier that can be passed to the MALLOCX_TCACHE(tc) + macro to explicitly use the specified cache rather than the + automatically managed one that is used by default. Each explicit cache + can be used by only one thread at a time; the application must assure + that this constraint holds. +

+ + "tcache.flush" + + (unsigned) + -w + [--enable-tcache] +

Flush the specified thread-specific cache (tcache). The + same considerations apply to this interface as to + "thread.tcache.flush" + , + except that the tcache will never be automatically discarded. +

+ + "tcache.destroy" + + (unsigned) + -w + [--enable-tcache] +

Flush the specified thread-specific cache (tcache) and + make the identifier available for use during a future tcache creation. +

+ + "arena.<i>.purge" + + (void) + -- +

Purge all unused dirty pages for arena <i>, or for + all arenas if <i> equals + "arenas.narenas" + . +

+ + "arena.<i>.decay" + + (void) + -- +

Trigger decay-based purging of unused dirty pages for + arena <i>, or for all arenas if <i> equals + "arenas.narenas" + . + The proportion of unused dirty pages to be purged depends on the current + time; see + "opt.decay_time" + for + details.

+ + "arena.<i>.reset" + + (void) + -- +

Discard all of the arena's extant allocations. This + interface can only be used with arenas created via + "arenas.extend" + . None + of the arena's discarded/cached allocations may accessed afterward. As + part of this requirement, all thread caches which were used to + allocate/deallocate in conjunction with the arena must be flushed + beforehand. This interface cannot be used if running inside Valgrind, + nor if the quarantine size is + non-zero.

+ + "arena.<i>.dss" + + (const char *) + rw +

Set the precedence of dss allocation as related to mmap + allocation for arena <i>, or for all arenas if <i> equals + + "arenas.narenas" + . See + + "opt.dss" + for supported + settings.

+ + "arena.<i>.lg_dirty_mult" + + (ssize_t) + rw +

Current per-arena minimum ratio (log base 2) of active + to dirty pages for arena <i>. Each time this interface is set and + the ratio is increased, pages are synchronously purged as necessary to + impose the new ratio. See + "opt.lg_dirty_mult" + + for additional information.

+ + "arena.<i>.decay_time" + + (ssize_t) + rw +

Current per-arena approximate time in seconds from the + creation of a set of unused dirty pages until an equivalent set of + unused dirty pages is purged and/or reused. Each time this interface is + set, all currently unused dirty pages are considered to have fully + decayed, which causes immediate purging of all unused dirty pages unless + the decay time is set to -1 (i.e. purging disabled). See + "opt.decay_time" + for + additional information.

+ + "arena.<i>.chunk_hooks" + + (chunk_hooks_t) + rw +

Get or set the chunk management hook functions for arena + <i>. The functions must be capable of operating on all extant + chunks associated with arena <i>, usually by passing unknown + chunks to the replaced functions. In practice, it is feasible to + control allocation for arenas created via + "arenas.extend" + such + that all chunks originate from an application-supplied chunk allocator + (by setting custom chunk hook functions just after arena creation), but + the automatically created arenas may have already created chunks prior + to the application having an opportunity to take over chunk + allocation.

+typedef struct {
+	chunk_alloc_t		*alloc;
+	chunk_dalloc_t		*dalloc;
+	chunk_commit_t		*commit;
+	chunk_decommit_t	*decommit;
+	chunk_purge_t		*purge;
+	chunk_split_t		*split;
+	chunk_merge_t		*merge;
+} chunk_hooks_t;

The chunk_hooks_t structure comprises function + pointers which are described individually below. jemalloc uses these + functions to manage chunk lifetime, which starts off with allocation of + mapped committed memory, in the simplest case followed by deallocation. + However, there are performance and platform reasons to retain chunks for + later reuse. Cleanup attempts cascade from deallocation to decommit to + purging, which gives the chunk management functions opportunities to + reject the most permanent cleanup operations in favor of less permanent + (and often less costly) operations. The chunk splitting and merging + operations can also be opted out of, but this is mainly intended to + support platforms on which virtual memory mappings provided by the + operating system kernel do not automatically coalesce and split, e.g. + Windows.

typedef void *(chunk_alloc_t)(void *chunk,
 size_t size,
 size_t alignment,
 bool *zero,
 bool *commit,
 unsigned arena_ind);
 

A chunk allocation function conforms to the + chunk_alloc_t type and upon success returns a pointer to + size bytes of mapped memory on behalf of arena + arena_ind such that the chunk's base address is a + multiple of alignment, as well as setting + *zero to indicate whether the chunk is zeroed and + *commit to indicate whether the chunk is + committed. Upon error the function returns NULL + and leaves *zero and + *commit unmodified. The + size parameter is always a multiple of the chunk + size. The alignment parameter is always a power + of two at least as large as the chunk size. Zeroing is mandatory if + *zero is true upon function entry. Committing is + mandatory if *commit is true upon function entry. + If chunk is not NULL, the + returned pointer must be chunk on success or + NULL on error. Committed memory may be committed + in absolute terms as on a system that does not overcommit, or in + implicit terms as on a system that overcommits and satisfies physical + memory needs on demand via soft page faults. Note that replacing the + default chunk allocation function makes the arena's + "arena.<i>.dss" + + setting irrelevant.

typedef bool (chunk_dalloc_t)(void *chunk,
 size_t size,
 bool committed,
 unsigned arena_ind);
 

+ A chunk deallocation function conforms to the + chunk_dalloc_t type and deallocates a + chunk of given size with + committed/decommited memory as indicated, on + behalf of arena arena_ind, returning false upon + success. If the function returns true, this indicates opt-out from + deallocation; the virtual memory mapping associated with the chunk + remains mapped, in the same commit state, and available for future use, + in which case it will be automatically retained for later reuse.

typedef bool (chunk_commit_t)(void *chunk,
 size_t size,
 size_t offset,
 size_t length,
 unsigned arena_ind);
 

A chunk commit function conforms to the + chunk_commit_t type and commits zeroed physical memory to + back pages within a chunk of given + size at offset bytes, + extending for length on behalf of arena + arena_ind, returning false upon success. + Committed memory may be committed in absolute terms as on a system that + does not overcommit, or in implicit terms as on a system that + overcommits and satisfies physical memory needs on demand via soft page + faults. If the function returns true, this indicates insufficient + physical memory to satisfy the request.

typedef bool (chunk_decommit_t)(void *chunk,
 size_t size,
 size_t offset,
 size_t length,
 unsigned arena_ind);
 

A chunk decommit function conforms to the + chunk_decommit_t type and decommits any physical memory + that is backing pages within a chunk of given + size at offset bytes, + extending for length on behalf of arena + arena_ind, returning false upon success, in which + case the pages will be committed via the chunk commit function before + being reused. If the function returns true, this indicates opt-out from + decommit; the memory remains committed and available for future use, in + which case it will be automatically retained for later reuse.

typedef bool (chunk_purge_t)(void *chunk,
 size_tsize,
 size_t offset,
 size_t length,
 unsigned arena_ind);
 

A chunk purge function conforms to the chunk_purge_t + type and optionally discards physical pages within the virtual memory + mapping associated with chunk of given + size at offset bytes, + extending for length on behalf of arena + arena_ind, returning false if pages within the + purged virtual memory range will be zero-filled the next time they are + accessed.

typedef bool (chunk_split_t)(void *chunk,
 size_t size,
 size_t size_a,
 size_t size_b,
 bool committed,
 unsigned arena_ind);
 

A chunk split function conforms to the chunk_split_t + type and optionally splits chunk of given + size into two adjacent chunks, the first of + size_a bytes, and the second of + size_b bytes, operating on + committed/decommitted memory as indicated, on + behalf of arena arena_ind, returning false upon + success. If the function returns true, this indicates that the chunk + remains unsplit and therefore should continue to be operated on as a + whole.

typedef bool (chunk_merge_t)(void *chunk_a,
 size_t size_a,
 void *chunk_b,
 size_t size_b,
 bool committed,
 unsigned arena_ind);
 

A chunk merge function conforms to the chunk_merge_t + type and optionally merges adjacent chunks, + chunk_a of given size_a + and chunk_b of given + size_b into one contiguous chunk, operating on + committed/decommitted memory as indicated, on + behalf of arena arena_ind, returning false upon + success. If the function returns true, this indicates that the chunks + remain distinct mappings and therefore should continue to be operated on + independently.

+ + "arenas.narenas" + + (unsigned) + r- +

Current limit on number of arenas.

+ + "arenas.initialized" + + (bool *) + r- +

An array of + "arenas.narenas" + + booleans. Each boolean indicates whether the corresponding arena is + initialized.

Current default per-arena approximate time in seconds + from the creation of a set of unused dirty pages until an equivalent set + of unused dirty pages is purged and/or reused, used to initialize + "arena.<i>.decay_time" + + during arena creation. See + "opt.decay_time" + for + additional information.

Extend the array of arenas by appending a new arena, + and returning the new arena index.

+ + "prof.thread_active_init" + + (bool) + rw + [--enable-prof] +

Control the initial setting for + "thread.prof.active" + + in newly created threads. See the + "opt.prof_thread_active_init" + + option for additional information.

+ + "prof.active" + + (bool) + rw + [--enable-prof] +

Control whether sampling is currently active. See the + + "opt.prof_active" + + option for additional information, as well as the interrelated + "thread.prof.active" + + mallctl.

+ + "prof.dump" + + (const char *) + -w + [--enable-prof] +

Dump a memory profile to the specified file, or if NULL + is specified, to a file according to the pattern + <prefix>.<pid>.<seq>.m<mseq>.heap, + where <prefix> is controlled by the + + "opt.prof_prefix" + + option.

+ + "prof.gdump" + + (bool) + rw + [--enable-prof] +

When enabled, trigger a memory profile dump every time + the total virtual memory exceeds the previous maximum. Profiles are + dumped to files named according to the pattern + <prefix>.<pid>.<seq>.u<useq>.heap, + where <prefix> is controlled by the + "opt.prof_prefix" + + option.

+ + "prof.reset" + + (size_t) + -w + [--enable-prof] +

Reset all memory profile statistics, and optionally + update the sample rate (see + "opt.lg_prof_sample" + + and + "prof.lg_sample" + ). +

+ + "prof.lg_sample" + + (size_t) + r- + [--enable-prof] +

Get the current sample rate (see + "opt.lg_prof_sample" + ). +

+ + "prof.interval" + + (uint64_t) + r- + [--enable-prof] +

Average number of bytes allocated between + interval-based profile dumps. See the + + "opt.lg_prof_interval" + + option for additional information.

+ + "stats.cactive" + + (size_t *) + r- + [--enable-stats] +

Pointer to a counter that contains an approximate count + of the current number of bytes in active pages. The estimate may be + high, but never low, because each arena rounds up when computing its + contribution to the counter. Note that the + "epoch" + mallctl has no bearing + on this counter. Furthermore, counter consistency is maintained via + atomic operations, so it is necessary to use an atomic operation in + order to guarantee a consistent read when dereferencing the pointer. +

+ + "stats.allocated" + + (size_t) + r- + [--enable-stats] +

Total number of bytes allocated by the + application.

+ + "stats.active" + + (size_t) + r- + [--enable-stats] +

Total number of bytes in active pages allocated by the + application. This is a multiple of the page size, and greater than or + equal to + "stats.allocated" + . + This does not include + + "stats.arenas.<i>.pdirty" + , nor pages + entirely devoted to allocator metadata.

+ + "stats.metadata" + + (size_t) + r- + [--enable-stats] +

Total number of bytes dedicated to metadata, which + comprise base allocations used for bootstrap-sensitive internal + allocator data structures, arena chunk headers (see + "stats.arenas.<i>.metadata.mapped" + ), + and internal allocations (see + "stats.arenas.<i>.metadata.allocated" + ).

+ + "stats.resident" + + (size_t) + r- + [--enable-stats] +

Maximum number of bytes in physically resident data + pages mapped by the allocator, comprising all pages dedicated to + allocator metadata, pages backing active allocations, and unused dirty + pages. This is a maximum rather than precise because pages may not + actually be physically resident if they correspond to demand-zeroed + virtual memory that has not yet been touched. This is a multiple of the + page size, and is larger than + "stats.active" + .

+ + "stats.mapped" + + (size_t) + r- + [--enable-stats] +

Total number of bytes in active chunks mapped by the + allocator. This is a multiple of the chunk size, and is larger than + + "stats.active" + . + This does not include inactive chunks, even those that contain unused + dirty pages, which means that there is no strict ordering between this + and + "stats.resident" + .

+ + "stats.retained" + + (size_t) + r- + [--enable-stats] +

Total number of bytes in virtual memory mappings that + were retained rather than being returned to the operating system via + e.g. munmap(2). Retained virtual memory is + typically untouched, decommitted, or purged, so it has no strongly + associated physical memory (see chunk hooks for details). Retained + memory is excluded from mapped memory statistics, e.g. + "stats.mapped" + . +

+ + "stats.arenas.<i>.dss" + + (const char *) + r- +

dss (sbrk(2)) allocation precedence as + related to mmap(2) allocation. See + "opt.dss" + for details. +

Minimum ratio (log base 2) of active to dirty pages. + See + "opt.lg_dirty_mult" + + for details.

+ + "stats.arenas.<i>.decay_time" + + (ssize_t) + r- +

Approximate time in seconds from the creation of a set + of unused dirty pages until an equivalent set of unused dirty pages is + purged and/or reused. See + "opt.decay_time" + + for details.

+ + "stats.arenas.<i>.nthreads" + + (unsigned) + r- +

Number of threads currently assigned to + arena.

+ + "stats.arenas.<i>.pactive" + + (size_t) + r- +

Number of pages in active runs.

+ + "stats.arenas.<i>.pdirty" + + (size_t) + r- +

Number of pages within unused runs that are potentially + dirty, and for which madvise(..., + MADV_DONTNEED) or + similar has not been called.

DEBUGGING MALLOC PROBLEMS

When debugging, it is a good idea to configure/build jemalloc with + the --enable-debug and --enable-fill + options, and recompile the program with suitable options and symbols for + debugger support. When so configured, jemalloc incorporates a wide variety + of run-time assertions that catch application errors such as double-free, + write-after-free, etc.

Programs often accidentally depend on “uninitialized” + memory actually being filled with zero bytes. Junk filling + (see the + "opt.junk" + + option) tends to expose such bugs in the form of obviously incorrect + results and/or coredumps. Conversely, zero + filling (see the + "opt.zero" + option) eliminates + the symptoms of such bugs. Between these two options, it is usually + possible to quickly detect, diagnose, and eliminate such bugs.

This implementation does not provide much detail about the problems + it detects, because the performance impact for storing such information + would be prohibitive. However, jemalloc does integrate with the most + excellent Valgrind tool if the + --enable-valgrind configuration option is enabled.

DIAGNOSTIC MESSAGES

If any of the memory allocation/deallocation functions detect an + error or warning condition, a message will be printed to file descriptor + STDERR_FILENO. Errors will result in the process + dumping core. If the + "opt.abort" + option is set, most + warnings are treated as errors.

The malloc_message variable allows the programmer + to override the function which emits the text strings forming the errors + and warnings if for some reason the STDERR_FILENO file + descriptor is not suitable for this. + malloc_message() takes the + cbopaque pointer argument that is + NULL unless overridden by the arguments in a call to + malloc_stats_print(), followed by a string + pointer. Please note that doing anything which tries to allocate memory in + this function is likely to result in a crash or deadlock.

All messages are prefixed by + “<jemalloc>: ”.

RETURN VALUES

Standard API

The malloc() and + calloc() functions return a pointer to the + allocated memory if successful; otherwise a NULL + pointer is returned and errno is set to + ENOMEM.

The posix_memalign() function + returns the value 0 if successful; otherwise it returns an error value. + The posix_memalign() function will fail + if: +

EINVAL

The alignment parameter is + not a power of 2 at least as large as + sizeof(void *). +

ENOMEM

Memory allocation error.

+

The aligned_alloc() function returns + a pointer to the allocated memory if successful; otherwise a + NULL pointer is returned and + errno is set. The + aligned_alloc() function will fail if: +

EINVAL

The alignment parameter is + not a power of 2. +

ENOMEM

Memory allocation error.

+

The realloc() function returns a + pointer, possibly identical to ptr, to the + allocated memory if successful; otherwise a NULL + pointer is returned, and errno is set to + ENOMEM if the error was the result of an + allocation failure. The realloc() + function always leaves the original buffer intact when an error occurs. +

The free() function returns no + value.

Non-standard API

The mallocx() and + rallocx() functions return a pointer to + the allocated memory if successful; otherwise a NULL + pointer is returned to indicate insufficient contiguous memory was + available to service the allocation request.

The xallocx() function returns the + real size of the resulting resized allocation pointed to by + ptr, which is a value less than + size if the allocation could not be adequately + grown in place.

The sallocx() function returns the + real size of the allocation pointed to by ptr. +

The nallocx() returns the real size + that would result from a successful equivalent + mallocx() function call, or zero if + insufficient memory is available to perform the size computation.

The mallctl(), + mallctlnametomib(), and + mallctlbymib() functions return 0 on + success; otherwise they return an error value. The functions will fail + if: +

EINVAL

newp is not + NULL, and newlen is too + large or too small. Alternatively, *oldlenp + is too large or too small; in this case as much data as possible + are read despite the error.

ENOENT

name or + mib specifies an unknown/invalid + value.

EPERM

Attempt to read or write void value, or attempt to + write read-only value.

EAGAIN

A memory allocation failure + occurred.

EFAULT

An interface with side effects failed in some way + not directly related to mallctl*() + read/write processing.

+

The malloc_usable_size() function + returns the usable size of the allocation pointed to by + ptr.

ENVIRONMENT

The following environment variable affects the execution of the + allocation functions: +

MALLOC_CONF

If the environment variable + MALLOC_CONF is set, the characters it contains + will be interpreted as options.

+

EXAMPLES

To dump core whenever a problem occurs: + 

ln -s 'abort:true' /etc/malloc.conf

+

To specify in the source a chunk size that is 16 MiB: + 

+malloc_conf = "lg_chunk:24";

The allocated + space is suitably aligned (after possible pointer coercion) for storage + of any type of object. + + The calloc function allocates + space for number objects, each + size bytes in length. The result is identical to + calling malloc with an argument of + number * size, with the + exception that the allocated memory is explicitly initialized to zero + bytes. + + The posix_memalign function + allocates size bytes of memory such that the + allocation's base address is a multiple of + alignment, and returns the allocation in the value + pointed to by ptr. The requested + alignment must be a power of 2 at least as large as + sizeof(void *). + + The aligned_alloc function + allocates size bytes of memory such that the + allocation's base address is a multiple of + alignment. The requested + alignment must be a power of 2. Behavior is + undefined if size is not an integral multiple of + alignment. + + The realloc function changes the + size of the previously allocated memory referenced by + ptr to size bytes. The + contents of the memory are unchanged up to the lesser of the new and old + sizes. If the new size is larger, the contents of the newly allocated + portion of the memory are undefined. Upon success, the memory referenced + by ptr is freed and a pointer to the newly + allocated memory is returned. Note that + realloc may move the memory allocation, + resulting in a different return value than ptr. + If ptr is NULL, the + realloc function behaves identically to + malloc for the specified size. + + The free function causes the + allocated memory referenced by ptr to be made + available for future allocations. If ptr is + NULL, no action occurs. + + + Non-standard API + The mallocx, + rallocx, + xallocx, + sallocx, + dallocx, + sdallocx, and + nallocx functions all have a + flags argument that can be used to specify + options. The functions only check the options that are contextually + relevant. Use bitwise or (|) operations to + specify one or more of the following: + + + MALLOCX_LG_ALIGN(la) + + + Align the memory allocation to start at an address + that is a multiple of (1 << + la). This macro does not validate + that la is within the valid + range. + + + MALLOCX_ALIGN(a) + + + Align the memory allocation to start at an address + that is a multiple of a, where + a is a power of two. This macro does not + validate that a is a power of 2. + + + + MALLOCX_ZERO + + Initialize newly allocated memory to contain zero + bytes. In the growing reallocation case, the real size prior to + reallocation defines the boundary between untouched bytes and those + that are initialized to contain zero bytes. If this macro is + absent, newly allocated memory is uninitialized. + + + MALLOCX_TCACHE(tc) + + + Use the thread-specific cache (tcache) specified by + the identifier tc, which must have been + acquired via the tcache.create + mallctl. This macro does not validate that + tc specifies a valid + identifier. + + + MALLOCX_TCACHE_NONE + + Do not use a thread-specific cache (tcache). Unless + MALLOCX_TCACHE(tc) or + MALLOCX_TCACHE_NONE is specified, an + automatically managed tcache will be used under many circumstances. + This macro cannot be used in the same flags + argument as + MALLOCX_TCACHE(tc). + + + MALLOCX_ARENA(a) + + + Use the arena specified by the index + a. This macro has no effect for regions that + were allocated via an arena other than the one specified. This + macro does not validate that a specifies an + arena index in the valid range. + + + + + The mallocx function allocates at + least size bytes of memory, and returns a pointer + to the base address of the allocation. Behavior is undefined if + size is 0. + + The rallocx function resizes the + allocation at ptr to be at least + size bytes, and returns a pointer to the base + address of the resulting allocation, which may or may not have moved from + its original location. Behavior is undefined if + size is 0. + + The xallocx function resizes the + allocation at ptr in place to be at least + size bytes, and returns the real size of the + allocation. If extra is non-zero, an attempt is + made to resize the allocation to be at least (size + + extra) bytes, though inability to allocate + the extra byte(s) will not by itself result in failure to resize. + Behavior is undefined if size is + 0, or if (size + extra + > SIZE_T_MAX). + + The sallocx function returns the + real size of the allocation at ptr. + + The dallocx function causes the + memory referenced by ptr to be made available for + future allocations. + + The sdallocx function is an + extension of dallocx with a + size parameter to allow the caller to pass in the + allocation size as an optimization. The minimum valid input size is the + original requested size of the allocation, and the maximum valid input + size is the corresponding value returned by + nallocx or + sallocx. + + The nallocx function allocates no + memory, but it performs the same size computation as the + mallocx function, and returns the real + size of the allocation that would result from the equivalent + mallocx function call, or + 0 if the inputs exceed the maximum supported size + class and/or alignment. Behavior is undefined if + size is 0. + + The mallctl function provides a + general interface for introspecting the memory allocator, as well as + setting modifiable parameters and triggering actions. The + period-separated name argument specifies a + location in a tree-structured namespace; see the section for + documentation on the tree contents. To read a value, pass a pointer via + oldp to adequate space to contain the value, and a + pointer to its length via oldlenp; otherwise pass + NULL and NULL. Similarly, to + write a value, pass a pointer to the value via + newp, and its length via + newlen; otherwise pass NULL + and 0. + + The mallctlnametomib function + provides a way to avoid repeated name lookups for applications that + repeatedly query the same portion of the namespace, by translating a name + to a “Management Information Base” (MIB) that can be passed + repeatedly to mallctlbymib. Upon + successful return from mallctlnametomib, + mibp contains an array of + *miblenp integers, where + *miblenp is the lesser of the number of components + in name and the input value of + *miblenp. Thus it is possible to pass a + *miblenp that is smaller than the number of + period-separated name components, which results in a partial MIB that can + be used as the basis for constructing a complete MIB. For name + components that are integers (e.g. the 2 in + arenas.bin.2.size), + the corresponding MIB component will always be that integer. Therefore, + it is legitimate to construct code like the following: + + The malloc_stats_print function + writes human-readable summary statistics via the + write_cb callback function pointer and + cbopaque data passed to + write_cb, or + malloc_message if + write_cb is NULL. This + function can be called repeatedly. General information that never + changes during execution can be omitted by specifying "g" as a character + within the opts string. Note that + malloc_message uses the + mallctl* functions internally, so + inconsistent statistics can be reported if multiple threads use these + functions simultaneously. If is + specified during configuration, “m” and “a” can + be specified to omit merged arena and per arena statistics, respectively; + “b”, “l”, and “h” can be specified to + omit per size class statistics for bins, large objects, and huge objects, + respectively. Unrecognized characters are silently ignored. Note that + thread caching may prevent some statistics from being completely up to + date, since extra locking would be required to merge counters that track + thread cache operations. + + + The malloc_usable_size function + returns the usable size of the allocation pointed to by + ptr. The return value may be larger than the size + that was requested during allocation. The + malloc_usable_size function is not a + mechanism for in-place realloc; rather + it is provided solely as a tool for introspection purposes. Any + discrepancy between the requested allocation size and the size reported + by malloc_usable_size should not be + depended on, since such behavior is entirely implementation-dependent. + + + + + TUNING + Once, when the first call is made to one of the memory allocation + routines, the allocator initializes its internals based in part on various + options that can be specified at compile- or run-time. + + The string specified via , the + string pointed to by the global variable malloc_conf, the + “name” of the file referenced by the symbolic link named + /etc/malloc.conf, and the value of the + environment variable MALLOC_CONF, will be interpreted, in + that order, from left to right as options. Note that + malloc_conf may be read before + main is entered, so the declaration of + malloc_conf should specify an initializer that contains + the final value to be read by jemalloc. + and malloc_conf are compile-time mechanisms, whereas + /etc/malloc.conf and + MALLOC_CONF can be safely set any time prior to program + invocation. + + An options string is a comma-separated list of option:value pairs. + There is one key corresponding to each opt.* mallctl (see the section for options + documentation). For example, abort:true,narenas:1 sets + the opt.abort and opt.narenas options. Some + options have boolean values (true/false), others have integer values (base + 8, 10, or 16, depending on prefix), and yet others have raw string + values. + + + IMPLEMENTATION NOTES + Traditionally, allocators have used + sbrk + 2 to obtain memory, which is + suboptimal for several reasons, including race conditions, increased + fragmentation, and artificial limitations on maximum usable memory. If + sbrk + 2 is supported by the operating + system, this allocator uses both + mmap + 2 and + sbrk + 2, in that order of preference; + otherwise only mmap + 2 is used. + + This allocator uses multiple arenas in order to reduce lock + contention for threaded programs on multi-processor systems. This works + well with regard to threading scalability, but incurs some costs. There is + a small fixed per-arena overhead, and additionally, arenas manage memory + completely independently of each other, which means a small fixed increase + in overall memory fragmentation. These overheads are not generally an + issue, given the number of arenas normally used. Note that using + substantially more arenas than the default is not likely to improve + performance, mainly due to reduced cache performance. However, it may make + sense to reduce the number of arenas if an application does not make much + use of the allocation functions. + + In addition to multiple arenas, unless + is specified during configuration, this + allocator supports thread-specific caching for small and large objects, in + order to make it possible to completely avoid synchronization for most + allocation requests. Such caching allows very fast allocation in the + common case, but it increases memory usage and fragmentation, since a + bounded number of objects can remain allocated in each thread cache. + + Memory is conceptually broken into equal-sized chunks, where the chunk + size is a power of two that is greater than the page size. Chunks are + always aligned to multiples of the chunk size. This alignment makes it + possible to find metadata for user objects very quickly. User objects are + broken into three categories according to size: small, large, and huge. + Multiple small and large objects can reside within a single chunk, whereas + huge objects each have one or more chunks backing them. Each chunk that + contains small and/or large objects tracks its contents as runs of + contiguous pages (unused, backing a set of small objects, or backing one + large object). The combination of chunk alignment and chunk page maps makes + it possible to determine all metadata regarding small and large allocations + in constant time. + + Small objects are managed in groups by page runs. Each run maintains + a bitmap to track which regions are in use. Allocation requests that are no + more than half the quantum (8 or 16, depending on architecture) are rounded + up to the nearest power of two that is at least sizeof(double). All other object size + classes are multiples of the quantum, spaced such that there are four size + classes for each doubling in size, which limits internal fragmentation to + approximately 20% for all but the smallest size classes. Small size classes + are smaller than four times the page size, large size classes are smaller + than the chunk size (see the opt.lg_chunk option), and + huge size classes extend from the chunk size up to the largest size class + that does not exceed PTRDIFF_MAX. + + Allocations are packed tightly together, which can be an issue for + multi-threaded applications. If you need to assure that allocations do not + suffer from cacheline sharing, round your allocation requests up to the + nearest multiple of the cacheline size, or specify cacheline alignment when + allocating. + + The realloc, + rallocx, and + xallocx functions may resize allocations + without moving them under limited circumstances. Unlike the + *allocx API, the standard API does not + officially round up the usable size of an allocation to the nearest size + class, so technically it is necessary to call + realloc to grow e.g. a 9-byte allocation to + 16 bytes, or shrink a 16-byte allocation to 9 bytes.

When so configured, jemalloc incorporates a wide variety + of run-time assertions that catch application errors such as double-free, + write-after-free, etc. + + Programs often accidentally depend on “uninitialized” + memory actually being filled with zero bytes. Junk filling + (see the opt.junk + option) tends to expose such bugs in the form of obviously incorrect + results and/or coredumps. Conversely, zero + filling (see the opt.zero option) eliminates + the symptoms of such bugs. Between these two options, it is usually + possible to quickly detect, diagnose, and eliminate such bugs. + + This implementation does not provide much detail about the problems + it detects, because the performance impact for storing such information + would be prohibitive. However, jemalloc does integrate with the most + excellent Valgrind tool if the + configuration option is enabled. + + + DIAGNOSTIC MESSAGES + If any of the memory allocation/deallocation functions detect an + error or warning condition, a message will be printed to file descriptor + STDERR_FILENO. Errors will result in the process + dumping core. If the opt.abort option is set, most + warnings are treated as errors. + + The malloc_message variable allows the programmer + to override the function which emits the text strings forming the errors + and warnings if for some reason the STDERR_FILENO file + descriptor is not suitable for this. + malloc_message takes the + cbopaque pointer argument that is + NULL unless overridden by the arguments in a call to + malloc_stats_print, followed by a string + pointer.

The allocated + space is suitably aligned (after possible pointer coercion) for storage + of any type of object. + + The calloc function allocates + space for number objects, each + size bytes in length. The result is identical to + calling malloc with an argument of + number * size, with the + exception that the allocated memory is explicitly initialized to zero + bytes. + + The posix_memalign function + allocates size bytes of memory such that the + allocation's base address is a multiple of + alignment, and returns the allocation in the value + pointed to by ptr. The requested + alignment must be a power of 2 at least as large as + sizeof(void *). + + The aligned_alloc function + allocates size bytes of memory such that the + allocation's base address is a multiple of + alignment. The requested + alignment must be a power of 2. Behavior is + undefined if size is not an integral multiple of + alignment. + + The realloc function changes the + size of the previously allocated memory referenced by + ptr to size bytes. The + contents of the memory are unchanged up to the lesser of the new and old + sizes. If the new size is larger, the contents of the newly allocated + portion of the memory are undefined. Upon success, the memory referenced + by ptr is freed and a pointer to the newly + allocated memory is returned. Note that + realloc may move the memory allocation, + resulting in a different return value than ptr. + If ptr is NULL, the + realloc function behaves identically to + malloc for the specified size. + + The free function causes the + allocated memory referenced by ptr to be made + available for future allocations. If ptr is + NULL, no action occurs. + + + Non-standard API + The mallocx, + rallocx, + xallocx, + sallocx, + dallocx, + sdallocx, and + nallocx functions all have a + flags argument that can be used to specify + options. The functions only check the options that are contextually + relevant. Use bitwise or (|) operations to + specify one or more of the following: + + + MALLOCX_LG_ALIGN(la) + + + Align the memory allocation to start at an address + that is a multiple of (1 << + la). This macro does not validate + that la is within the valid + range. + + + MALLOCX_ALIGN(a) + + + Align the memory allocation to start at an address + that is a multiple of a, where + a is a power of two. This macro does not + validate that a is a power of 2. + + + + MALLOCX_ZERO + + Initialize newly allocated memory to contain zero + bytes. In the growing reallocation case, the real size prior to + reallocation defines the boundary between untouched bytes and those + that are initialized to contain zero bytes. If this macro is + absent, newly allocated memory is uninitialized. + + + MALLOCX_TCACHE(tc) + + + Use the thread-specific cache (tcache) specified by + the identifier tc, which must have been + acquired via the tcache.create + mallctl. This macro does not validate that + tc specifies a valid + identifier. + + + MALLOCX_TCACHE_NONE + + Do not use a thread-specific cache (tcache). Unless + MALLOCX_TCACHE(tc) or + MALLOCX_TCACHE_NONE is specified, an + automatically managed tcache will be used under many circumstances. + This macro cannot be used in the same flags + argument as + MALLOCX_TCACHE(tc). + + + MALLOCX_ARENA(a) + + + Use the arena specified by the index + a. This macro has no effect for regions that + were allocated via an arena other than the one specified. This + macro does not validate that a specifies an + arena index in the valid range. + + + + + The mallocx function allocates at + least size bytes of memory, and returns a pointer + to the base address of the allocation. Behavior is undefined if + size is 0. + + The rallocx function resizes the + allocation at ptr to be at least + size bytes, and returns a pointer to the base + address of the resulting allocation, which may or may not have moved from + its original location. Behavior is undefined if + size is 0. + + The xallocx function resizes the + allocation at ptr in place to be at least + size bytes, and returns the real size of the + allocation. If extra is non-zero, an attempt is + made to resize the allocation to be at least (size + + extra) bytes, though inability to allocate + the extra byte(s) will not by itself result in failure to resize. + Behavior is undefined if size is + 0, or if (size + extra + > SIZE_T_MAX). + + The sallocx function returns the + real size of the allocation at ptr. + + The dallocx function causes the + memory referenced by ptr to be made available for + future allocations. + + The sdallocx function is an + extension of dallocx with a + size parameter to allow the caller to pass in the + allocation size as an optimization. The minimum valid input size is the + original requested size of the allocation, and the maximum valid input + size is the corresponding value returned by + nallocx or + sallocx. + + The nallocx function allocates no + memory, but it performs the same size computation as the + mallocx function, and returns the real + size of the allocation that would result from the equivalent + mallocx function call, or + 0 if the inputs exceed the maximum supported size + class and/or alignment. Behavior is undefined if + size is 0. + + The mallctl function provides a + general interface for introspecting the memory allocator, as well as + setting modifiable parameters and triggering actions. The + period-separated name argument specifies a + location in a tree-structured namespace; see the section for + documentation on the tree contents. To read a value, pass a pointer via + oldp to adequate space to contain the value, and a + pointer to its length via oldlenp; otherwise pass + NULL and NULL. Similarly, to + write a value, pass a pointer to the value via + newp, and its length via + newlen; otherwise pass NULL + and 0. + + The mallctlnametomib function + provides a way to avoid repeated name lookups for applications that + repeatedly query the same portion of the namespace, by translating a name + to a “Management Information Base” (MIB) that can be passed + repeatedly to mallctlbymib. Upon + successful return from mallctlnametomib, + mibp contains an array of + *miblenp integers, where + *miblenp is the lesser of the number of components + in name and the input value of + *miblenp. Thus it is possible to pass a + *miblenp that is smaller than the number of + period-separated name components, which results in a partial MIB that can + be used as the basis for constructing a complete MIB. For name + components that are integers (e.g. the 2 in + arenas.bin.2.size), + the corresponding MIB component will always be that integer. Therefore, + it is legitimate to construct code like the following: + + The malloc_stats_print function + writes human-readable summary statistics via the + write_cb callback function pointer and + cbopaque data passed to + write_cb, or + malloc_message if + write_cb is NULL. This + function can be called repeatedly. General information that never + changes during execution can be omitted by specifying "g" as a character + within the opts string. Note that + malloc_message uses the + mallctl* functions internally, so + inconsistent statistics can be reported if multiple threads use these + functions simultaneously. If is + specified during configuration, “m” and “a” can + be specified to omit merged arena and per arena statistics, respectively; + “b”, “l”, and “h” can be specified to + omit per size class statistics for bins, large objects, and huge objects, + respectively. Unrecognized characters are silently ignored. Note that + thread caching may prevent some statistics from being completely up to + date, since extra locking would be required to merge counters that track + thread cache operations. + + + The malloc_usable_size function + returns the usable size of the allocation pointed to by + ptr. The return value may be larger than the size + that was requested during allocation. The + malloc_usable_size function is not a + mechanism for in-place realloc; rather + it is provided solely as a tool for introspection purposes. Any + discrepancy between the requested allocation size and the size reported + by malloc_usable_size should not be + depended on, since such behavior is entirely implementation-dependent. + + + + + TUNING + Once, when the first call is made to one of the memory allocation + routines, the allocator initializes its internals based in part on various + options that can be specified at compile- or run-time. + + The string specified via , the + string pointed to by the global variable malloc_conf, the + “name” of the file referenced by the symbolic link named + /etc/malloc.conf, and the value of the + environment variable MALLOC_CONF, will be interpreted, in + that order, from left to right as options. Note that + malloc_conf may be read before + main is entered, so the declaration of + malloc_conf should specify an initializer that contains + the final value to be read by jemalloc. + and malloc_conf are compile-time mechanisms, whereas + /etc/malloc.conf and + MALLOC_CONF can be safely set any time prior to program + invocation. + + An options string is a comma-separated list of option:value pairs. + There is one key corresponding to each opt.* mallctl (see the section for options + documentation). For example, abort:true,narenas:1 sets + the opt.abort and opt.narenas options. Some + options have boolean values (true/false), others have integer values (base + 8, 10, or 16, depending on prefix), and yet others have raw string + values. + + + IMPLEMENTATION NOTES + Traditionally, allocators have used + sbrk + 2 to obtain memory, which is + suboptimal for several reasons, including race conditions, increased + fragmentation, and artificial limitations on maximum usable memory. If + sbrk + 2 is supported by the operating + system, this allocator uses both + mmap + 2 and + sbrk + 2, in that order of preference; + otherwise only mmap + 2 is used. + + This allocator uses multiple arenas in order to reduce lock + contention for threaded programs on multi-processor systems. This works + well with regard to threading scalability, but incurs some costs. There is + a small fixed per-arena overhead, and additionally, arenas manage memory + completely independently of each other, which means a small fixed increase + in overall memory fragmentation. These overheads are not generally an + issue, given the number of arenas normally used. Note that using + substantially more arenas than the default is not likely to improve + performance, mainly due to reduced cache performance. However, it may make + sense to reduce the number of arenas if an application does not make much + use of the allocation functions. + + In addition to multiple arenas, unless + is specified during configuration, this + allocator supports thread-specific caching for small and large objects, in + order to make it possible to completely avoid synchronization for most + allocation requests. Such caching allows very fast allocation in the + common case, but it increases memory usage and fragmentation, since a + bounded number of objects can remain allocated in each thread cache. + + Memory is conceptually broken into equal-sized chunks, where the chunk + size is a power of two that is greater than the page size. Chunks are + always aligned to multiples of the chunk size. This alignment makes it + possible to find metadata for user objects very quickly. User objects are + broken into three categories according to size: small, large, and huge. + Multiple small and large objects can reside within a single chunk, whereas + huge objects each have one or more chunks backing them. Each chunk that + contains small and/or large objects tracks its contents as runs of + contiguous pages (unused, backing a set of small objects, or backing one + large object). The combination of chunk alignment and chunk page maps makes + it possible to determine all metadata regarding small and large allocations + in constant time. + + Small objects are managed in groups by page runs. Each run maintains + a bitmap to track which regions are in use. Allocation requests that are no + more than half the quantum (8 or 16, depending on architecture) are rounded + up to the nearest power of two that is at least sizeof(double). All other object size + classes are multiples of the quantum, spaced such that there are four size + classes for each doubling in size, which limits internal fragmentation to + approximately 20% for all but the smallest size classes. Small size classes + are smaller than four times the page size, large size classes are smaller + than the chunk size (see the opt.lg_chunk option), and + huge size classes extend from the chunk size up to the largest size class + that does not exceed PTRDIFF_MAX. + + Allocations are packed tightly together, which can be an issue for + multi-threaded applications. If you need to assure that allocations do not + suffer from cacheline sharing, round your allocation requests up to the + nearest multiple of the cacheline size, or specify cacheline alignment when + allocating. + + The realloc, + rallocx, and + xallocx functions may resize allocations + without moving them under limited circumstances. Unlike the + *allocx API, the standard API does not + officially round up the usable size of an allocation to the nearest size + class, so technically it is necessary to call + realloc to grow e.g. a 9-byte allocation to + 16 bytes, or shrink a 16-byte allocation to 9 bytes. Growth and shrinkage + trivially succeeds in place as long as the pre-size and post-size both round + up to the same size class. No other API guarantees are made regarding + in-place resizing, but the current implementation also tries to resize large + and huge allocations in place, as long as the pre-size and post-size are + both large or both huge. In such cases shrinkage always succeeds for large + size classes, but for huge size classes the chunk allocator must support + splitting (see arena.<i>.chunk_hooks). + Growth only succeeds if the trailing memory is currently available, and + additionally for huge size classes the chunk allocator must support + merging. + + Assuming 2 MiB chunks, 4 KiB pages, and a 16-byte quantum on a + 64-bit system, the size classes in each category are as shown in . + + + Size classes + + + + + + + Category + Spacing + Size + + + + + Small + lg + [8] + + + 16 + [16, 32, 48, 64, 80, 96, 112, 128] + + + 32 + [160, 192, 224, 256] + + + 64 + [320, 384, 448, 512] + + + 128 + [640, 768, 896, 1024] + + + 256 + [1280, 1536, 1792, 2048] + + + 512 + [2560, 3072, 3584, 4096] + + + 1 KiB + [5 KiB, 6 KiB, 7 KiB, 8 KiB] + + + 2 KiB + [10 KiB, 12 KiB, 14 KiB] + + + Large + 2 KiB + [16 KiB] + + + 4 KiB + [20 KiB, 24 KiB, 28 KiB, 32 KiB] + + + 8 KiB + [40 KiB, 48 KiB, 54 KiB, 64 KiB] + + + 16 KiB + [80 KiB, 96 KiB, 112 KiB, 128 KiB] + + + 32 KiB + [160 KiB, 192 KiB, 224 KiB, 256 KiB] + + + 64 KiB + [320 KiB, 384 KiB, 448 KiB, 512 KiB] + + + 128 KiB + [640 KiB, 768 KiB, 896 KiB, 1 MiB] + + + 256 KiB + [1280 KiB, 1536 KiB, 1792 KiB] + + + Huge + 256 KiB + [2 MiB] + + + 512 KiB + [2560 KiB, 3 MiB, 3584 KiB, 4 MiB] + + + 1 MiB + [5 MiB, 6 MiB, 7 MiB, 8 MiB] + + + 2 MiB + [10 MiB, 12 MiB, 14 MiB, 16 MiB] + + + 4 MiB + [20 MiB, 24 MiB, 28 MiB, 32 MiB] + + + 8 MiB + [40 MiB, 48 MiB, 56 MiB, 64 MiB] + + + ... + ... + + + 512 PiB + [2560 PiB, 3 EiB, 3584 PiB, 4 EiB] + + + 1 EiB + [5 EiB, 6 EiB, 7 EiB] + + + +

When so configured, jemalloc incorporates a wide variety + of run-time assertions that catch application errors such as double-free, + write-after-free, etc. + + Programs often accidentally depend on “uninitialized” + memory actually being filled with zero bytes. Junk filling + (see the opt.junk + option) tends to expose such bugs in the form of obviously incorrect + results and/or coredumps. Conversely, zero + filling (see the opt.zero option) eliminates + the symptoms of such bugs. Between these two options, it is usually + possible to quickly detect, diagnose, and eliminate such bugs. + + This implementation does not provide much detail about the problems + it detects, because the performance impact for storing such information + would be prohibitive. However, jemalloc does integrate with the most + excellent Valgrind tool if the + configuration option is enabled. + + + DIAGNOSTIC MESSAGES + If any of the memory allocation/deallocation functions detect an + error or warning condition, a message will be printed to file descriptor + STDERR_FILENO. Errors will result in the process + dumping core. If the opt.abort option is set, most + warnings are treated as errors. + + The malloc_message variable allows the programmer + to override the function which emits the text strings forming the errors + and warnings if for some reason the STDERR_FILENO file + descriptor is not suitable for this. + malloc_message takes the + cbopaque pointer argument that is + NULL unless overridden by the arguments in a call to + malloc_stats_print, followed by a string + pointer. Please note that doing anything which tries to allocate memory in + this function is likely to result in a crash or deadlock. + + All messages are prefixed by + “<jemalloc>: ”. + + + RETURN VALUES + + Standard API + The malloc and + calloc functions return a pointer to the + allocated memory if successful; otherwise a NULL + pointer is returned and errno is set to + ENOMEM. + + The posix_memalign function + returns the value 0 if successful; otherwise it returns an error value. + The posix_memalign function will fail + if: + + + EINVAL + + The alignment parameter is + not a power of 2 at least as large as + sizeof(void *). + + + + ENOMEM + + Memory allocation error. + + + + + The aligned_alloc function returns + a pointer to the allocated memory if successful; otherwise a + NULL pointer is returned and + errno is set. The + aligned_alloc function will fail if: + + + EINVAL + + The alignment parameter is + not a power of 2. + + + + ENOMEM + + Memory allocation error. + + + + + The realloc function returns a + pointer, possibly identical to ptr, to the + allocated memory if successful; otherwise a NULL + pointer is returned, and errno is set to + ENOMEM if the error was the result of an + allocation failure. The realloc + function always leaves the original buffer intact when an error occurs. + + + The free function returns no + value. + + + Non-standard API + The mallocx and + rallocx functions return a pointer to + the allocated memory if successful; otherwise a NULL + pointer is returned to indicate insufficient contiguous memory was + available to service the allocation request. + + The xallocx function returns the + real size of the resulting resized allocation pointed to by + ptr, which is a value less than + size if the allocation could not be adequately + grown in place. + + The sallocx function returns the + real size of the allocation pointed to by ptr. + + + The nallocx returns the real size + that would result from a successful equivalent + mallocx function call, or zero if + insufficient memory is available to perform the size computation. + + The mallctl, + mallctlnametomib, and + mallctlbymib functions return 0 on + success; otherwise they return an error value. The functions will fail + if: + + + EINVAL + + newp is not + NULL, and newlen is too + large or too small.
