Redis 3.2 release notes
=======================
--------------------------------------------------------------------------------
Upgrade urgency levels:
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.
--------------------------------------------------------------------------------
================================================================================
Redis 3.2.0 Released Fri May 06 08:47:10 CEST 2016
================================================================================
Upgrade urgency HIGH: 3.2-RC users should upgrade ASAP to this more
stable release of Redis.
Hello, this is Redis 3.2.0 stable! And with the new release there is a new
format for the changelog. Now it is composed of a "letter" like the one
you are reading, followed by all the commits composing the release for people
interested in the details.
There are a few changes between the latest release candidate of Redis 3.2
and the final 3.2.0 release. The main ones are the obvious bug fixes you
can find detailed below, also a few new things:
Critical bugs fixed:
* There was a problem in the way a cluster instance loaded the AOF that
could cause data written via scripts to be lost during reshardings.
New things:
* There is a new very powerful BITFIELD command. Check the documentation
here: http://redis.io/commands/BITFIELD
* CONFIG GET is allowed during the loading of the dataset.
* The DEBUG command have new features and can show an help with DEBUG HELP.
* redis-cli show hits about the commands arguments to the right.
* GEORADIUS got a STORE / STOREDIST option to store the result into a target
key (as as orted set) instead of reporting it to the user.
* Redis Cluster replicas migration now works in a slightly different way. In
the past a slave could migrate only to a master that used to have slaves
in the past (and if there was still trace of this information). Now instead
if a new slave gets at least a slot, and at least one other master in the
cluster has a slave, then the new master is considered a valid target for
replica migration. So if it will be orphaned and there is a spare slave
it will get one.
* CLUSTER SLOTS output now includes the node ID (in a backward compatible
manner).
* A lot of bug fixes you can read in the commits details below, with the
authors that kindly provided many useful patches. Thanks.
As usually what "stable" means is that we are confident the release is mature,
however do your tests before putting it into production in your environemnt
as it's fresh meat anyway.
Cheers,
Salvatore

https://github.com/antirez/redis/commit/708f486c77b455fa7ae1e87cf31278474eb9d432
This fixes a bug introduced by d827dbf, and makes the code consistent
with the logic of always allowing, while the cluster is down, commands
that don't target any key.
As a side effect the code is also simpler now.

I've renamed maxmemoryToString to evictPolicyToString since that is
more accurate (and easier to mentally connect with the correct data), as
well as updated the function to user server.maxmemory_policy rather than
server.maxmemory. Now with a default config it is actually returning
the correct policy rather than volatile-lru.

https://github.com/antirez/redis/commit/38cf2bd257d09b360be6adf450d59592a359696d
The test works but is very slow so far, since it involves resharding
1/5 of all the cluster slots from master 0 to the other 4 masters and
back into the original master.

| New masters with slots are now targets of migration if others are.
| By antirez, 2016-05-02 16:41:56 +0200
+--------------------------------------------------------------------------------
https://github.com/antirez/redis/commit/7b618823c189c24313effbccda7022d167ea419c
This fixes issue #3043.
Before this fix, after a complete resharding of a master slots
to other nodes, the master remains empty and the slaves migrate away
to other masters with non-zero nodes. However the old master now empty,
is no longer considered a target for migration, because the system has
no way to tell it had slaves in the past.
This fix leaves the algorithm used in the past untouched, but adds a
new rule. When a new or old master which is empty and without slaves,
are assigend with their first slot, if other masters in the cluster have
slaves, they are automatically considered to be targets for replicas
migration.

+--------------------------------------------------------------------------------
https://github.com/antirez/redis/commit/0b69c9865619b54b75576e67aaafe7b018734bec
This fix was suggested by Anthony LaTorre, that provided also a good
test case that was used to verify the fix.
The problem with the old implementation is that, the time returned by
a timer event (that is the time after it want to run again) is added
to the event *start time*. So if the event takes, in order to run, more
than the time it says it want to be scheduled again for running, an
infinite loop is triggered.

| BITFIELD command initial implementation.
| By antirez, 2016-02-25 23:31:45 +0100
+--------------------------------------------------------------------------------
https://github.com/antirez/redis/commit/761a77287107ce53dbf4755f1435cc9660b6c86d
The new bitfield command is an extension to the Redis bit operations,
where not just single bit operations are performed, but the array of
bits composing a string, can be addressed at random, not aligned
offsets, with any width unsigned and signed integers like u8, s5, u10
(up to 64 bit signed integers and 63 bit unsigned integers).
The BITFIELD command supports subcommands that can SET, GET, or INCRBY
those arbitrary bit counters, with multiple overflow semantics.
Trivial and credits:
A similar command was imagined a few times in the past, but for
some reason looked a bit far fetched or not well specified.
Finally the command was proposed again in a clear form by
Yoav Steinberg from Redis Labs, that proposed a set of commands on
arbitrary sized integers stored at bit offsets.
Starting from this proposal I wrote an initial specification of a single
command with sub-commands similar to what Yoav envisioned, using short
names for types definitions, and adding control on the overflow.
This commit is the resulting implementation.
Examples:
BITFIELD mykey OVERFLOW wrap INCRBY i2 10 -1 GET i2 10

| Cluster: include node IDs in SLOTS output.
| By antirez, 2016-01-29 12:00:38 +0100
+--------------------------------------------------------------------------------
https://github.com/antirez/redis/commit/0f3fb0097ae70e36ee65468b79f0be4160934bb4
CLUSTER SLOTS now includes IDs in the nodes description associated with
a given slot range. Certain client libraries implementations need a way
to reference a node in an unique way, so they were relying on CLUSTER
NODES, that is not a stable API and may change frequently depending on
Redis Cluster future requirements.

~~~~~~~~~~~~~~~~~~~~~~~~~~ OLD STYLE CHANGELOG ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
--[ Redis 3.2.0 RC3 (version 3.1.103) ] Release date: 28 jan 2016
Upgrade urgency MODERATE: this release fixes a non trivial Sentinel crash.
* [FIX] avg_ttl reporting in INFO improved. (Salvatore Sanfilippo)
* [FIX] Sentinel: improve handling of known Sentinel instances.
(Salvatore Sanfilippo, thanks to Paweł Kowalczykf or the original
crash report).
* [FIX] Redis Cluster address update (via gossip section) processing improved
to avoid initiating inwanted handshakes.
--[ Redis 3.2.0 RC2 (version 3.1.102) ] Release date: 25 jan 2016
Upgrade urgency MODERATE: this release fixes important Redis Cluster bugs.
* [FIX] Many fixes to MIGRATE multiple keys implementation. The command
could handle errors in a faulty way leading to crashes or other
unexpected behaviors. MIGRATE command refactoring.
(The analysis of the faulty conditions was conducted by
Kevin McGehee. The fix was developed by Salvatore Sanfilippo)
* [FIX] A Redis Cluster node crash was fixed because of wrong handling of
node->slaveof pointers.
(Reported by JackyWoo, fixed by Salvatore Sanfilippo)
* [FIX] Fix redis-trib rebalance when nodes need to be left empty because
the specified weight is zero.
(Reported by Shahar Mor, fixed by Salvatore Sanfilippo)
* [FIX] MIGRATE: Never send -ASK redirections for MIGRATE when there are
open slots. Redis-trib and other cluster management utility must
always be free to move keys between nodes about open slots, in order
to reshard, fix the cluster configuration, and so forth.
(Salvatore Sanfilippo)
* [FIX] Lua debugger crash when printing too deeply nested objects.
(Reported by Paul Kulchenko, fixed by Salvatore Sanfilippo)
* [FIX] Redis-cli implementation of Lua debugging now allows to use the
SCRIPT DEBUG command directly, switching to debugging mode as needed.
(Reported by Paul Kulchenko, fixed by Salvatore Sanfilippo)
* [FIX] Redis-trib is now able to fix more errors. A new CLUSTER subcommand
called BUMPEPOCH was introduced in order to support new modes
for the "fix" subcommand. (Salvatore Sanfilippo)
* [NEW] Redis proctected mode: this feature improves Redis security and makes
harder to run Redis in a configuration that is unsecure because no
firewalling was used in order to protect Redis from external accesses.
See this Reddit post for more info: https://www.reddit.com/r/redis/comments/3zv85m/new_security_feature_redis_protected_mode/ (Salvatore Sanfilippo)
* [NEW] Cluster/Sentinel tests now use OSX leak to perform leak detection
at the end of every unit. (Salvatore Sanfilippo)
* [NEW] Detect and show server crashes during Cluster/Sentinel tests.
(Salvatore Sanfilippo)
* [NEW] More reliable Cluster/Sentinel test becuase of timing errors and
-LOADING errors. (Salvatore Sanfilippo)
--[ Redis 3.2.0 RC1 (version 3.1.101) ] Release date: 23 dec 2015
This is the first release candidate of Redis 3.2. The changelog above shows
what's new in this release. In the next of the following weeks we'll test
in depth every feature and we'll release new RCs as bugs are discovered
and fixed. Note that while 3.2 looks solid already, it contains many changes
to its internals. It's still fresh code compared to 3.0.
General changes:
* [NEW] Lua scripts "effect replication". Makes possible to write scripts
with side effects, use of random commands, and so forth.
(Salvatore Sanfilippo)
* [NEW] Lua scripts selective replication. Makes possible to replicate to
slaves and AOF only selected parts of a script. (Design by
Yossi Gottlieb and Salvatore Sanfilippo, implemented by Salvatore)
* [NEW] Geo indexing support via GEOADD, GEORADIUS and other commands.
See http://redis.io/commands/geoadd for more information.
(Initially implemented in a fork of Redis called "Ardb".
Matt Stancliff "imported back" the work to Redis and created the
initial API and implementation. Salvatore Sanfilippo modified
the API and the implementation, fixed bugs, improved performances
and unified the duplicated code with t_zset.c)
* [NEW] Lua debugger. A complete stepping, remote debugger for Lua scripts.
Video here: https://www.youtube.com/watch?v=IMvRfStaoyM
(Salvatore Sanfilippo with many feedbacks and testing from
Itamar Haber)
* [NEW] SDS improvements for speed and maximum string length.
This makes Redis more memory efficient in different use cases.
(Design and implementation by Oran Agra, some additional work
by Salvatore Sanfilippo)
* [NEW] Modify Jemalloc size classes to make certain Redis objects fit
better, improving memory efficiency. (Oran Agra)
* [NEW] Better consistency behavior between masters and slaves for expired
keys. The slaves are only able to logically consider a key expired
even before receiving the `DEL` command from the master. This avoids
the delay there is sometimes between the natural expire of the key
and the moment the slave is notified. (Salvatore Sanfilippo)
* [NEW] Support daemon supervision by upstart or systemd (Pierre-Yves Ritschard)
* [NEW] New encoding for the List type: Quicklists. Very important memory
savings and storage space in RDB gains (up to 10x sometimes).
(Design and implementation by Matt Stancliff. RDB storage reworked
by Salvatore Sanfilippo)
* [NEW] SPOP with optional count argument. (Initial implementation by
Alon Diamant, mostly reimplemented by Salvatore Sanfilippo for speed
and in order to make the replication of a this class of commands,
having as logical effect the execution of multiple commands, possible).
* [NEW] Support for RDB AUX fields. Now RDB files contain additional info
like the creation date, version of Redis generating it and so forth.
(Salvatore Sanfilippo)
* [NEW] Faster RDB loading via the RESIZEDB opcode to avoid useless hash tables
rehashings. (Salvatore Sanfilippo)
* [NEW] HSTRLEN command. (@landmime and Salvatore Sanfilippo)
* [NEW] CONFIG SET/GET implementations refactored, partially rewritten,
now exposing more config options. (Salvatore Sanfilippo)
* [NEW] CLUSTER NODES major speedup. (Salvatore Sanfilippo)
* [NEW] CLIENT KILL TYPE MASTER, to kill (disconnect) masters from slaves.
(Salvatore Sanfilippo)
* [NEW] Jemalloc updated to 4.0.3 (Salvatore Sanfilippo)
* [NEW] DEBUG RESTART/CRASH-AND-RECOVER [delay] (Salvatore Sanfilippo)
* [NEW] CLIENT REPLY command implemented: ON, OFF and SKIP modes.
(Salvatore Sanfilippo)
* [NEW] Crash report produced by Redis on crash improved. (Salvatore Sanfilippo)
* [NEW] Better memory test on crash. (Salvatore Sanfilippo)
Redis Cluster changes:
All the Redis Cluster changes in 3.2 were backported to 3.0, so there is
technically nothing new for now in this release. The most important things
are:
* Cluster rebalancing.
* A pipelined MIGRATE command which is 10x faster and makes resharding
and rebalancing faster.
* Improved replicas migration.
* As a side effect of quicklists encoding (see above items), moving big
lists between nodes is now a lot faster.
Redis Sentinel changes:
* [NEW] Sentinel connection sharing. Makes Sentinels able to scale to
monitor many masters. (Salvatore Sanfilippo)
* [NEW] New SENTINEL INFO-CACHE command. (Matt Stancliff)
* More things backported to Redis 3.0 in the past, so no longer news of 3.2.
Migrating from 3.0 to 3.2
=========================
Redis 3.0 is mostly a strict subset of 3.2, you should not have any problem
upgrading your application from 3.0 to 3.2. However this is a list of small
non-backward compatible changes introduced in the 3.2 release:
* The default configuration file now binds to 127.0.0.1.
* Slaves try to no longer expose stale data about already expired keys.
* The RDB format changed. Redis 3.2 is still able to read 3.0 (and all the
past versions) files, but not the other way around.
* Behavior on crash may be different. The crash log format changed and
the memory test executed is now different.
--------------------------------------------------------------------------------
Credits: For each release, a list of changes with the relative author is
provided. Where not specified the implementation and design is done by
Salvatore Sanfilippo. Thanks to Redis Labs for making all this possible.
Also many thanks to all the other contributors and the amazing community
we have.
Commit messages may contain additional credits.
Cheers,
Salvatore
