Redis 2.4.13

Use safe dictionary iterator from KEYS
Every matched key in a KEYS call is checked for expiration. When the key is set to expire, the call to `getExpire` will assert that the key also exists in the main dictionary. This in turn causes a rehashing step to be executed. Rehashing a dictionary when there is an iterator active may result in the iterator emitting duplicate entries, or not emitting some entries at all. By using a safe iterator, the rehash step is omitted.

-Hello! This file is just a placeholder, since this is the "unstable" branch
-of Redis, the place where all the development happens.
+Redis 2.4 release notes

-There is no release notes for this branch, it gets forked into another branch
-every time there is a partial feature freeze in order to eventually create
-a new stable release.
+Migrating from 2.2 to 2.4
+=========================

-Usually "unstable" is stable enough for you to use it in development environments
-however you should never use it in production environments. It is possible
-to download the latest stable release here:
+Redis 2.2 is mostly a strict subset of 2.4.
+The only thing you should be aware is that you can't use .rdb and AOF files
+generated with 2.4 into a 2.2 instance.

-    http://download.redis.io/releases/redis-stable.tar.gz
+2.4 slaves can be attached to 2.2 masters, but not the contrary, and only for
+the time needed to perform the version upgrade.

-More information is available at http://redis.io
+From the point of view of the API Redis 2.4 only adds new commands
+(other commands now accepts a variable number of arguments) so you don't need
+to modify your program in order to use Redis 2.4.

-Happy hacking!

+CHANGELOG
+---------
+
+What's new in Redis 2.4.13
+=========================
+
+UPGRADE URGENCY: high for all the users of the KEYS command, otherwise low.
+
+* [BUGFIX] Fix for KEYS command: if the DB contains keys with expires the KEYS
+           command may return the wrong output, having duplicated or missing
+           keys. See issue #487 and #488 on github for details.
+
+What's new in Redis 2.4.12
+=========================
+
+UPGRADE URGENCY: low if you don't experience any of the fixed problems.
+
+* [BUGFIX] Limit the amount of memory consumed by the slow log.
+* [BUGFIX] --test-memory option fixes.

+* [BUGFIX] Fixed compilation with latest clang.
+* [BUGFIX] Fixed handling of empty sorted sets produced in RDB by
+           very old Redis versions (1.2.x).
+
+What's new in Redis 2.4.7
+=========================
+
+UPGRADE URGENCY: low/moderate if you don't experience any of the fixed problems.
+
+* [BUGFIX] Fixed false positive in issue #141 regression test.
+* [BUGFIX] Slave should not expire keys when loading an RDB after a SYNC.
+* [BUGFIX] Don't increment stats for key misses / hits when key is written.
+* [BUGFIX] sds.c library now don't allocate more than 1MB ahead.
+* 32 bit instances without a maxmemory set now get a default limit of 3.5GB with
+  maxmemory-policy set to noeviction.
+* Better crash report on crash (containing current client and command arguments).
+
+What's new in Redis 2.4.6
+=========================
+
+* [BUGFIX] Fixed issue #141 part 1: Possible protocol desyncs when clients send
+           wrong protocol is now fixed. (See issue 141 for more details)
+* [BUGFIX] Fixed issue #141 part 2: Connection of multiple slaves used to result
+           from time to time into corrupted protocol send to slaves connected
+           after the first one. (See issue 141 for more details)
+* [BUGFIX] Do not propagate DEBUG LOADAOF.
+* New INFO contains information such as ip/port/state for every conneced slave.
+* Show GCC version in INFO output.
+
+What's new in Redis 2.4.5
+=========================
+
+* [BUGFIX] Fixed a ZUNIONSTORE/ZINTERSTORE bug that can cause a NaN to be
+           inserted as a sorted set element score. This happens when one of the
+           elements has +inf/-inf score and the weight used is 0.
+* [BUGFIX] Fixed memory leak in CLIENT INFO.
+* [BUGFIX] Fixed a non critical SORT bug (Issue 224).
+* [BUGFIX] Fixed a replication bug: now the timeout configuration is respected
+           during the connection with the master.
+* --quiet option implemented in the Redis test.
+
+What's new in Redis 2.4.4
+=========================
+
+* [BUGFIX] jemalloc upgraded to version 2.2.5, previous versions had a
+  potentially serious issue when allocating big memory areas, something that
+  Redis actually does. However we never received bug reports that appear
+  to be caused by jemalloc.
+* [BUGFIX] DISCARD now clears DIRTY_CAS flag in the client. Now the next
+  transaction will not fail if the previous transaction used WATCH and
+  the key was touched.
+* CLIENT LIST output modified to include the last command executed by clients.
+* Better bug report on crash.
+* Protocol errors are now logged for loglevel >= verbose.
+* Two new INFO fields related to AOF, that can be useful when investigating
+  Redis issues.
+
+What's new in Redis 2.4.3
+=========================
+
+* redis-cli now supports 'single quotes' style strings.
+* It is possible to disable password auth with CONFIG SET.
+* Some section of redis.conf better documented.
+* Default timeout for client connections now is 0 (no timeout).
+* I/O buffer length modified for better performances with big payloads.
+* Fixed crash on SPARC due to improper alighment due to bad assumptions about data types size.
+* CLIENT LIST output improved, code refactored.
+* [BUGFIX] Max log message length set to 4k to avoid truncation in INFO output written in the log file after a crash.
+* [BUGFIX] Close client connection when the query buffer reaches 1GB and log informaiton about the offending client, instead of crashing the instance when the query buffer reaches 2GB (for sds.c string overflow). This is related to issue #141 (github issues) and should fix the effect of this rare bug related to replication, but the cause is still not perfectly clear.
+
+What's new in Redis 2.4.2
+=========================
+
+* [BUGFIX] Unix socket creation mask config directive fixed.
+* [BUGFIX] Fixed a bug that forced Redis to continously rewrite the AOF file
+           when a manual BGREWRITEAOF was issued during a BGSAVE was
+           still in progress.
+* [BUGFIX] Fixed a server crash resulting from bad handling of SLAVEOF NO ONE.
+* [BUGFIX] Fixed a memory leak in redis-cli.
+* Debian/Ubuntu Redis system-wide installation script added under /utils.
+
+What's new in Redis 2.4.1
+=========================
+
+* [BUGFIX] FLUSHALL was not replicated nor written into the Append Only File.
+* [BUGFIX] FLUSHALL now only performs a sync SAVE if there is at least
+           one save point configured.
+
+What's new in Redis 2.4.0
+=========================
+
+* [BUGFIX] redis-cli segfault with single numerical argument fixed.

+* [BUGFIX] Exit with Fatal error at startup on RDB loading errors.
+* redis-check-dump: RDB version 2 now supported.
+* More informative error when DEBUG RELOAD fails.
+* Added a config directive for a Unix socket mask.
+* CONFIG SET/GET for loglevel.
+
+What's new in Redis 2.3.11 (2.4 Release Candidate 8)
+====================================================
+
+* [BUGFIX] Fixed a rare but possible AOF race condition that could result into
+           duplicated commands inside the AOF.
+* [BUGFIX] Fixed issue 620, don't segfault on corrupted (by hand) AOF.
+* [BUGFIX] Fixed compilation on Mac/PPC.
+* [BUGFIX] Don't replicate SAVE.

+* Include port number on error when can't bind.
+* AOF fsync is now performed in background when fsync policy is 'everysec'.
+* AOF performances improved moving in background a possibly slow close(2) call.
+* AOF protocol synthesis speedup.
+
+What's new in Redis 2.3.10 (2.4 Release Candidate 7)
+====================================================
+
+* [BUGFIX] Fixed issue 593 (BRPOPLPUSH related crash).
+* [BUGFIX] Fixed an issue with the networking layer that may prevent Redis from sending the whole reply back to client under extreme conditions.
+
+What's new in Redis 2.3.9 (2.4 Release Candidate 6)
+===================================================
+
+* [BUGFIX] Fixed a bug with the automatic AOF rewrite causing continuous
+  rewrites for AOF files bigger than 4 GB.
+* New maxmemory tests.
+
+What's new in Redis 2.3.8 (2.4 Release Candidate 5)
+===================================================
+
+Compared to Redis 2.3.7 (RC4) there are the following changes:
+
+* [BUGFIX] HDEL: Abort deleting fields when hash is removed.
+* [BUGFIX] Fix adding bulk reply when getcwd fails.
+
+WHAT'S NEW IN REDIS 2.4 compared to the 2.2 version?
+====================================================
+
+* Specially encoded sorted sets, now small sorted sets will use little memory.
+* Native persistence of specially encoded data types (ziplists, zipmaps,

+* OBJECT command for objects introspection.
+* CLIENT command for clients introspection.
+* Non blocking slave -> master connection.
+* Better redis-cli connection handling. New redis-cli features.
+* Better redis-benchmark, now able to benchmark user provided commands.
+* Colorized Make.
+* VM deprecated. Still supported but with a big warning... don't use it.
+* Many speed optimizations and bug fixes.
+
+Credits: Where not specified the implementation and design are done by
+Salvatore Sanfilippo and Pieter Noordhuis. Thanks to VMware for making all
+this possible. Also many thanks to all the other contributors and the amazing
+community we have.

-Redis Manifesto
-===============
-
-1 - A DSL for Abstract Data Types. Redis is a DSL (Domain Specific Language)
-    that manipulates abstract data types and implemented as a TCP daemon.
-    Commands manipulate a key space where keys are binary-safe strings and
-    values are different kinds of abstract data types. Every data type
-    represents an abstract version of a fundamental data structure. For instance
-    Redis Lists are an abstract representation of linked lists. In Redis, the
-    essence of a data type isn't just the kind of operations that the data types
-    support, but also the space and time complexity of the data type and the
-    operations performed upon it.
-
-2 - Memory storage is #1. The Redis data set, composed of defined key-value
-    pairs, is primarily stored in the computer's memory. The amount of memory in
-    all kinds of computers, including entry-level servers, is increasing
-    significantly each year. Memory is fast, and allows Redis to have very
-    predictable performance. Datasets composed of 10k or 40 millions keys will
-    perform similarly. Complex data types like Redis Sorted Sets are easy to
-    implement and manipulate in memory with good performance, making Redis very
-    simple. Redis will continue to explore alternative options (where data can
-    be optionally stored on disk, say) but the main goal of the project remains
-    the development of an in-memory database.
-
-3 - Fundamental data structures for a fundamental API. The Redis API is a direct
-    consequence of fundamental data structures. APIs can often be arbitrary but
-    not an API that resembles the nature of fundamental data structures. If we
-    ever meet intelligent life forms from another part of the universe, they'll
-    likely know, understand and recognize the same basic data structures we have
-    in our computer science books. Redis will avoid intermediate layers in API,
-    so that the complexity is obvious and more complex operations can be
-    performed as the sum of the basic operations.
-
-4 - Code is like a poem; it's not just something we write to reach some
-    practical result. Sometimes people that are far from the Redis philosophy
-    suggest using other code written by other authors (frequently in other
-    languages) in order to implement something Redis currently lacks. But to us
-    this is like if Shakespeare decided to end Enrico IV using the Paradiso from
-    the Divina Commedia. Is using any external code a bad idea? Not at all. Like
-    in "One Thousand and One Nights" smaller self contained stories are embedded
-    in a bigger story, we'll be happy to use beautiful self contained libraries
-    when needed. At the same time, when writing the Redis story we're trying to
-    write smaller stories that will fit in to other code.
-
-5 - We're against complexity. We believe designing systems is a fight against
-    complexity. We'll accept to fight the complexity when it's worthwhile but
-    we'll try hard to recognize when a small feature is not worth 1000s of lines
-    of code. Most of the time the best way to fight complexity is by not
-    creating it at all.
-
-6 - Two levels of API. The Redis API has two levels: 1) a subset of the API fits
-    naturally into a distributed version of Redis and 2) a more complex API that
-    supports multi-key operations. Both are useful if used judiciously but
-    there's no way to make the more complex multi-keys API distributed in an
-    opaque way without violating our other principles. We don't want to provide
-    the illusion of something that will work magically when actually it can't in
-    all cases. Instead we'll provide commands to quickly migrate keys from one
-    instance to another to perform multi-key operations and expose the tradeoffs
-    to the user.
-
-7 - We optimize for joy. We believe writing code is a lot of hard work, and the
-    only way it can be worth is by enjoying it. When there is no longer joy in
-    writing code, the best thing to do is stop. To prevent this, we'll avoid
-    taking paths that will make Redis less of a joy to develop.

 Internally, Hiredis splits the command in different arguments and will

-### Reader max buffer
-
-Both when using the Reader API directly or when using it indirectly via a
-normal Redis context, the redisReader structure uses a buffer in order to
-accumulate data from the server.
-Usually this buffer is destroyed when it is empty and is larger than 16
-kb in order to avoid wasting memory in unused buffers
-
-However when working with very big payloads destroying the buffer may slow
-down performances considerably, so it is possible to modify the max size of
-an idle buffer changing the value of the `maxbuf` field of the reader structure
-to the desired value. The special value of 0 means that there is no maximum
-value for an idle buffer, so the buffer will never get freed.
-
-For instance if you have a normal Redis context you can set the maximum idle
-buffer to zero (unlimited) just with:
-
-    context->reader->maxbuf = 0;
-
-This should be done only in order to maximize performances when working with
-large payloads. The context should be set back to `REDIS_READER_MAX_BUF` again
-as soon as possible in order to prevent allocation of useless memory.

@@ -3,306 +3,8 @@ bug fixes are all mentioned, but internal enhancements are omitted here for
 brevity (even though they are more fun to write about).  Much more detail can be
 found in the git revision history:

-    https://github.com/jemalloc/jemalloc
-
-* 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 manifect 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.<i>.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.<i>.dss", and "stats.arenas.<i>.dss" mallctls,
-    which provide control over dss/mmap precedence.
-  - Add the "arena.<i>.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.<i>.bins.<j>.highruns" and
-    "stats.arenas.<i>.lruns.<j>.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.

-jemalloc is a general purpose malloc(3) 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.
+jemalloc is a general-purpose scalable concurrent malloc(3) implementation.
+This distribution is a stand-alone "portable" implementation that currently
+targets Linux and Apple OS X.  jemalloc is included as the default allocator in
+the FreeBSD and NetBSD operating systems, and it is used by the Mozilla Firefox
+web browser on Microsoft Windows-related platforms.  Depending on your needs,
+one of the other divergent versions may suit your needs better than this
+distribution.

- * TLS/TSD-agnostic macro-based implementation of thread-specific data.  There
- * are four macros that support (at least) three use cases: file-private,
- * library-private, and library-private inlined.  Following is an example
- * library-private tsd variable:
- *
- * In example.h:
- *   typedef struct {
- *           int x;
- *           int y;
- *   } example_t;
- *   #define EX_INITIALIZER JEMALLOC_CONCAT({0, 0})
- *   malloc_tsd_protos(, example, example_t *)
- *   malloc_tsd_externs(example, example_t *)
- * In example.c:
- *   malloc_tsd_data(, example, example_t *, EX_INITIALIZER)
- *   malloc_tsd_funcs(, example, example_t *, EX_INITIALIZER,
- *       example_tsd_cleanup)
- *
- * The result is a set of generated functions, e.g.:
- *
- *   bool example_tsd_boot(void) {...}
- *   example_t **example_tsd_get() {...}
- *   void example_tsd_set(example_t **val) {...}
- *
- * Note that all of the functions deal in terms of (a_type *) rather than
- * (a_type)  so that it is possible to support non-pointer types (unlike
- * pthreads TSD).  example_tsd_cleanup() is passed an (a_type *) pointer that is
- * cast to (void *).  This means that the cleanup function needs to cast *and*
- * dereference the function argument, e.g.:
- *
- *   void
- *   example_tsd_cleanup(void *arg)
- *   {
- *           example_t *example = *(example_t **)arg;
- *
- *           [...]
- *           if ([want the cleanup function to be called again]) {
- *                   example_tsd_set(&example);
- *           }
- *   }
- *
- * If example_tsd_set() is called within example_tsd_cleanup(), it will be
- * called again.  This is similar to how pthreads TSD destruction works, except
- * that pthreads only calls the cleanup function again if the value was set to
- * non-NULL.
