Redis 2.6.9

Sometimes it is much simpler to debug complex Redis installations if it
is possible to assign clients a name that is displayed in the CLIENT
LIST output.

This is the case, for example, for "leaked" connections. The ability to
provide a name to the client makes it quite trivial to understand what
is the part of the code implementing the client not releasing the
resources appropriately.

Behavior:

    CLIENT SETNAME: set a name for the client, or remove the current
                    name if an empty name is set.
    CLIENT GETNAME: get the current name, or a nil.
    CLIENT LIST: now displays the client name if any.

Thanks to Mark Gravell for pushing this idea forward.

 Redis 2.6 release notes
+=======================
 
-Migrating from 2.4 to 2.6
-=========================
+** IMPORTANT ** Check the 'Migrating from 2.4 to 2.6' section at the end of
+                this file for information about what changed between 2.4 and
+                2.6 and how this may affect your application.
 
-Redis 2.4 is mostly a strict subset of 2.6. However there are a few things
-that you should be aware of:
+--------------------------------------------------------------------------------
+Upgrade urgency levels:
 
-* You can't use .rdb and AOF files generated with 2.6 into a 2.4 instance.
-* 2.4 slaves can be attached to 2.6 masters, but not the contrary, and only
-  for the time needed to perform the version upgrade.
+LOW:      No need to upgrade unless there are new features you want to use.
+MODERATE: Program an upgrade of the server, but it's not urgent.
+HIGH:     There is a critical bug that may affect a subset of users. Upgrade!
+CRITICAL: There is a critical bug affecting MOST USERS. Upgrade ASAP.
+--------------------------------------------------------------------------------
 
-There are also a few API differences, that are unlikely to cause problems,
-but it is better to keep them in mind:
+--[ Redis 2.6.9 ]
 
-* SORT now will refuse to sort in numerical mode elements that can't be parsed
-  as numbers.
-* EXPIREs now all have millisecond resolution (but this is very unlikely to
-  break code that was not conceived exploting the previous resolution error
-  in some way.)
-* INFO output is a bit different now, and contains empty lines and comments
-  starting with '#'. All the major clients should be already fixed to work
-  with the new INFO format.
+UPGRADE URGENCY: MODERATE if you use replication.
 
-Also the following redis.conf and CONFIG GET / SET parameters changed name:
+* [BUGFIX]   Changing master at runtime (SLAVEOF command) in presence of
+             network problems, or in very rapid succession, could result
+             in non-critical problems (GitHub Issue #828).
+* [IMPROVED] CLINGET GETNAME and SETNAME to set and query connection names
+             reported by CLIENT LIST. Very useful for debugging of
+             problems.
+* [IMPROVED] redis-cli is now able to transfer an RDB file from a remote
+             server to a local file using the --rdb <filename> command
+             line option.
 
-    * hash-max-zipmap-entries, now replaced by hash-max-ziplist-entries
-    * hash-max-zipmap-value, now replaced by hash-max-ziplist-value
-    * glueoutputbuf was no completely removed as it does not make sense
+--[ Redis 2.6.8 ]
 
----------
-CHANGELOG
----------
+UPGRADE URGENCY: MODERATE if you use Lua scripting. Otherwise LOW.
 
-What's new in Redis 2.6.0
-=========================
+* [BUGFIX]   Multiple fixes for EVAL (issue #872).
+* [BUGFIX]   Fix overflow in mstime() in redis-cli and benchmark.
+* [BUGFIX]   Fix Linux / PPC64 behavior by correcting endianess detection.
+* [BUGFIX]   Fix NetBSD build by defining _XOPEN_SOURCE appropriately.
+* [BUGFIX]   Added missing license and copyright in a few places.
+* [BUGFIX]   Better error reporting when fd event creation fails.
 
-UPGRADE URGENCY: We suggest new users to start with 2.6.0, and old users to
-                 upgrade after some testing of the application with the new
-                 Redis version.
+--[ Redis 2.6.7 ]
+
+UPGRADE URGENCY: MODERATE (unless you BLPOP using the same key multiple times).
+
+* [BUGFIX]   Don't crash if BLPOP & co are called with the same key repeated
+             multiple times (Issue #801).
+
+--[ Redis 2.6.6 ]
+
+UPGRADE URGENCY: CRITICAL if you experienced one more more crashes.
+                 MODERATE if Redis is running fine for you.
+
+* [BUGFIX]   Jemalloc updated to 3.2.0.
+
+--[ Redis 2.6.5 ]
+
+UPGRADE URGENCY: MODERATE
+
+Warning: this release of Redis introduces a different behavior in MULTI/EXEC
+         handling of errors. This was done because the new behavior is safer
+         compared to the old one, and should not break any code targeting
+         Redis 2.6 in a critical way.
+
+         For more information check http://redis.io/topics/transactions
+
+* [IMPROVED] RDB/AOF childern now log amount of additional memory used
+             because of copy on write.
+* [BUGFIX]   MIGRATE non critical fixes (see commits for details).
+* [BUGFIX]   MULTI/EXEC: now EXEC aborts on errors before EXEC.
+* [BUGFIX]   Fix integer overflow in zunionInterGenericCommand resulting
+             into Z[INTER|UNION][STORE] commands to crash under extremely
+             unlikely conditions (almost impossible in real world).
+* [BUGFIX]   EVALSHA is now case insensitive (and will not crash).
+
+--[ Redis 2.6.4 ]
+
+UPGRADE URGENCY: LOW
+
+* [IMPROVED] BSD license and copyright notice added to every .c and .h file.
+
+--[ Redis 2.6.2 ]
+
+UPGRADE URGENCY: LOW
+
+* [BUGFIX]   The compilation fix for RHLE5 in 2.6.1 was broken. Fixed.
+* [IMPROVED] Linenoise updated, now supports Ctrl+w.
+
+---[ Redis 2.6.1 ]
+
+UPGRADE URGENCY: LOW
+
+* [BUGFIX]   Compilation on Linux < 2.6.17 or glibc < 2.6 fixed (RHLE5 & co).
+
+---[ Redis 2.6.0 ]
+
+UPGRADE URGENCY: HIGH
+
+* [BUGFIX]   Allow AUTH when server is in -BUSY state because of a slow script.
+* [BUGFIX]   MULTI/EXEC flow now makes sense when observed in MONITOR
+* [BUGFIX]   SCRIPT KILL now uses different error prefixes for different errors.
+* [BUGFIX]   Default memory limit for 32bit archs lowered from 3.5 to 3 GB.
+* [BUGFIX]   redis-check-dump is now compatible with RDB files generated by 2.6.
+* [IMPROVED] New field in INFO: slave_read_only.
+
+---[ Redis 2.5.14 (2.6 Release Candidate 8) ]
+
+* [BUGFIX]   Fixed compilation on FreeBSD.
+* [IMPROVED] SRANDMEMBER <count> that returns multiple random elements.
+* [IMPROVED] Sentinel backported to 2.6. It will be taken in sync with 2.8.
+* [IMPROVED] Helper function for scripting to return errors and status replies.
+* [IMPROVED] SORT by nosort [ASC|DESC] uses sorted set elements ordering.
+* [BUGFIX]   Better resistence to system clock skew.
+* [IMPROVED] Warn the user when the configured maxmemory seems odd.
+* [BUGFIX]   Hashing function is now murmurhash2 for security purposes.
+* [IMPROVED] Install script no longer uses a template but redis.conf itself.
+
+---[ Redis 2.5.13 (2.6 Release Candidate 7) ]
+
+UPGRADE URGENCY: HIGH
+
+* [BUGFIX]   Theoretical bug in ziplist fixed.
+* [BUGFIX]   Better out of memory handling (Log produced in log file).
+* [BUGFIX]   Incrementally flush RDB file on slave side while performing the
+             first synchronization with the master. This makes Redis less
+             blocking in environments where disk I/O is slow.
+* [BUGFIX]   Don't crash with Lua's redis.call() without arguments.
+* [BUGFIX]   Don't crash after a big number of Lua calls on 32 bit systems
+             because of a failed assertion.
+* [BUGFIX]   Fix SORT behaviour when called from scripting.
+* [BUGFIX]   Adjust slave PING period accordingly to REDIS_HZ define.
+* [BUGFIX]   BITCOUNT: fix crash on overflowing arguments.
+* [BUGFIX]   Return an error when SELECT argument is not an integer.
+* [BUGFIX]   Blocking operations on lists were completely reimplemented for
+             correctness. Now blocking list ops and pushes originated from
+             Lua scripts will play well together and will be replicated
+             and transmitted to the AOF correctly.
+* [IMPROVED] Send async PING before starting replication to avoid blocking if
+             master allows us to connect but it is actually not able to reply.
+* [IMPROVED] Support slave-priority for Redis Sentinel.
+* [IMPROVED] Hiredis library updated.
+
+---[ Redis 2.5.12 (2.6 Release Candidate 6) ]
+
+UPGRADE URGENCY: MODERATE.
+
+* [BUGFIX]   Fixed a timing attack on AUTH (Issue #560).
+* [BUGFIX]   Don't assume that "char" is signed.
+* [BUGFIX]   Check that we have connection before enabling pipe mode.
+* [BUGFIX]   Use the optimized version of the function to convert a double to
+             its string representation. Compilation was disabled because of
+             a typo in the #if statement.
+* [IMPROVED} REPLCONF internal command introduced, now INFO shows slaves with
+             correct port numbers. This makes 2.5.12 Redis Sentinel compatible.
+* [IMPROVED] Truncate short write from the AOF for a cleaner restart. On short
+             writes (for instance out of space) Redis will now try to remove
+             the half-written data so that the next restart will work without
+             the need for the "redis-check-aof" utility.
+* [IMPROVED] New in INFO: aof_last_bgrewrite_status
+* [IMPROVED] Allow Pub/Sub in contexts where other commands are blocked.
+* [BUGFIX]   mark fd as writable when EPOLLERR or EPOLLHUP is returned by
+             epoll_wait.
+
+---[ Redis 2.5.11 (2.6 Release Candidate 5) ]
+
+UPGRADE URGENCY: HIGH.
+
+* [BUGFIX]   Fixed Hash corruption when loading an RDB file generated by
+             previous versions of Redis that encoded hashes using
+             a different ziplist encoding format for small integers.
+             All the fileds that are integers in the range 0-255 may not
+             be recognized, or duplicated un updates, causing a crash
+             when the ziplist is converted to a real hash. (Issue #547).
+* [BUGFIX]   Fixed the count of memory used by output buffers in the
+             setDeferredMultiBulkLength() function.
+
+---[ Redis 2.5.10 (2.6 Release Candidate 4) ]
+
+UPGRADE URGENCY: HIGH.
+
+* [BUGFIX]   Allow PREFIX to be overwritten on "make install".
+* [BUGFIX]   Run the test with just one client if the computer is slow.
+* [BUGFIX]   Event port support in our event driven libray.
+* [BUGFIX]   Jemalloc updated to 3.0.0. This fixes a possibly AOF rewrite issue.
+             See https://github.com/antirez/redis/issues/504 for info.
+* [BUGFIX]   Fixed issue #516: ZINTERSTORE / ZUNIONSTORE with mixed sets/zsets.
+* [BUGFIX]   Set fd to writable when poll(2) detects POLLERR or POLLHUP event.
+* [BUGFIX]   Fixed RESTORE hash failure (Issue #532).
+* [IMPROVED] Allow an AOF rewrite buffer > 2GB (Related to issue #504).
+* [IMPROVED] Server cron function frequency is now configurable (REDIS_HZ).
+* [IMPROVED] Better, less blocking expired keys collection algorithm.
+* [FEATURE]  New commands: BITOP and BITCOUNT.
+* [FEATURE]  redis-cli --pipe for mass import.
+
+What's new in Redis 2.5.9 (aka 2.6 Release Candidate 3)
+=======================================================
+
+UPGRADE URGENCY: critical, upgrade ASAP.
+
+* [BUGFIX] Fix for issue #500 (https://github.com/antirez/redis/pull/500).
+           Redis 2.6-RC1 and RC2 may corrupt ziplist-encoded sorted sets
+           produced by Redis 2.4.x.
+* [BUGFIX] Fixed several bugs in init.d script.
+* [BUGFIX] syncio.c functions modified for speed and correctness. On osx
+           (and possibly other BSD-based systems) the slave would block on
+           replication to send the SYNC command when the master was not
+           available. This is fixed now, but was not affecting Linux installs.
+* Now when slave-serve-stale-data is set to yes and the master is down, instead
+  of reporting a generic error Redis replies with -MASTERDOWN.
+
+What's new in Redis 2.5.8 (aka 2.6 Release Candidate 2)
+=======================================================
+
+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 2.5.7 (aka 2.6 Release Candidate 1)
+=======================================================
+
+UPGRADE URGENCY: upgrade not recommended because this is an RC release.
+
+* This is the first release candidate for Redis 2.6. We are not aware of
+  bugs, but part of this code is young and was never tested in production
+  environments, so handle with care.

-WARNING: are you a possible Redis contributor?
-         Before implementing what is listed in this file
-         please drop a message in the Redis google group or chat with
-         antirez or pietern on irc.freenode.org #redis to check if the work
-         is already in progress and if the feature is still interesting for
-         us, and *how* exactly this can be implemented to have good changes
-         of a merge. Otherwise it is probably wasted work! Thank you
-
-
-CLUSTER
-=======
-
-* Implement rehashing and cluster check in redis-trib.
-* Reimplement MIGRATE / RESTORE to use just in memory buffers (no disk at
-  all). This will require touching a lot of the RDB stuff around, but we may
-  hand with faster persistence for RDB.
-* Implement the slave nodes semantics and election.
-* Allow redis-trib to create a cluster-wide snapshot (using SYNC).
-* Allow redis-trib to restore a cluster-wide snapshot (implement UPLOAD?).
-
-SCRIPTING
-=========
-
-* SCRIPT FLUSH or alike to start a fresh interpreter?
-
-OPTIMIZATIONS
-=============
-
-* SORT: Don't copy the list into a vector when BY argument is constant.
-* Write the hash table size of every db in the dump, so that Redis can resize the hash table just one time when loading a big DB.
-* Read-only mode for slaves.
-* Redis big lists as linked lists of small ziplists?
-  Possibly a simple heuristic that join near nodes when some node gets smaller than the low_level, and split it into two if gets bigger than high_level.
-
-KNOWN BUGS
-==========
-
-* #519: Slave may have expired keys that were never read in the master (so a DEL
-  is not sent in the replication channel) but are already expired since
-  a lot of time. Maybe after a given delay that is undoubtably greater than
-  the replication link latency we should expire this key on the slave on
-  access?

 For example, [hiredis-rb](https://github.com/pietern/hiredis-rb/blob/master/ext/hiredis_ext/reader.c)
 uses customized reply object functions to create Ruby objects.
 
+### 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.

+* 3.2.0 (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.

+ * 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.

-	 * extend an unaligned mapping, our best option is to switch to the
-	 * slow method until mmap() returns another aligned mapping.  This will
-	 * tend to leave a gap in the memory map that is too small to cause
-	 * later problems for the optimistic method.
-	 *
-	 * Another possible confounding factor is address space layout
-	 * randomization (ASLR), which causes mmap(2) to disregard the
-	 * requested address.  mmap_unaligned tracks whether the previous
-	 * chunk_alloc_mmap() execution received any unaligned or relocated
-	 * mappings, and if so, the current execution will immediately fall
-	 * back to the slow method.  However, we keep track of whether the fast
-	 * method would have succeeded, and if so, we make a note to try the
-	 * fast method next time.
+	 * Optimistically try mapping precisely the right amount before falling
+	 * back to the slow method, with the expectation that the optimistic
