Redis 6.2 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.
SECURITY: There are security fixes in the release.
--------------------------------------------------------------------------------
================================================================================
Redis 6.2.0 GA Released Tue Feb 22 14:00:00 IST 2021
================================================================================
Upgrade urgency: SECURITY if you use 32bit build of redis (see bellow), MODERATE
if you used earlier versions of Redis 6.2, LOW otherwise.
Integer overflow on 32-bit systems (CVE-2021-21309):
Redis 4.0 or newer uses a configurable limit for the maximum supported bulk
input size. By default, it is 512MB which is a safe value for all platforms.
If the limit is significantly increased, receiving a large request from a client
may trigger several integer overflow scenarios, which would result with buffer
overflow and heap corruption.
Here is a comprehensive list of changes in this release compared to 6.2 RC3,
each one includes the PR number that added it, so you can get more details
at https://github.com/redis/redis/pull/<number>
Bug fixes:
* Avoid 32-bit overflows when proto-max-bulk-len is set high (#8522)
* Fix broken protocol in client tracking tracking-redir-broken message (#8456)
* Avoid unsafe field name characters in INFO commandstats, errorstats, modules (#8492)
* XINFO able to access expired keys during CLIENT PAUSE WRITE (#8436)
* Fix allowed length for REPLCONF ip-address, needed due to Sentinel's support for hostnames (#8517)
* Fix broken protocol in redis-benchmark when used with -a or --dbnum (#8486)
* XADD counts deleted records too when considering switching to a new listpack (#8390)
Bug fixes that are only applicable to previous releases of Redis 6.2:
* Fixes in GEOSEARCH bybox (accuracy and mismatch between width and height) (#8445)
* Fix risk of OOM panic in HRANDFIELD, ZRANDMEMBER commands with huge negative count (#8429)
* Fix duplicate replicas issue in Sentinel, needed due to hostname support (#8481)
* Fix Sentinel configuration rewrite, an improvement of #8271 (#8480)
Command behavior changes:
* SRANDMEMBER uses RESP3 array type instead of set type (#8504)
* EXPIRE, EXPIREAT, SETEX, GETEX: Return error when provided expire time overflows (#8287)
Other behavior changes:
* Remove ACL subcommand validation if fully added command exists. (#8483)
Improvements:
* Optimize sorting in GEORADIUS / GEOSEARCH with COUNT (#8326)
* Optimize HRANDFIELD and ZRANDMEMBER case 4 when ziplist encoded (#8444)
* Optimize in-place replacement of elements in HSET, HINCRBY, LSET (#8493)
* Remove redundant list to store pubsub patterns (#8472)
* Add --insecure option to command line tools (#8416)
Info fields and introspection changes:
* Add INFO fields to track progress of BGSAVE, AOFRW, replication (#8414)
Modules:
* RM_ZsetRem: Delete key if empty, the bug could leave empty zset keys (#8453)
* RM_HashSet: Add COUNT_ALL flag and set errno (#8446)
================================================================================
Redis 6.2 RC3 Released Tue Feb 1 14:00:00 IST 2021
================================================================================
Upgrade urgency LOW: This is the third Release Candidate of Redis 6.2.

New commands / args:
* Add HRANDFIELD and ZRANDMEMBER commands (#8297)
* Add FAILOVER command (#8315)
* Add GETEX, GETDEL commands (#8327)
* Add PXAT/EXAT arguments to SET command (#8327)
* Add SYNC arg to FLUSHALL and FLUSHDB, and ASYNC/SYNC arg to SCRIPT FLUSH (#8258)
Sentinel:
* Add hostname support to Sentinel (#8282)
* Prevent file descriptors from leaking into Sentinel scripts (#8242)
* Fix config file line order dependency and config rewrite sequence (#8271)
New configuration options:
* Add set-proc-title config option to disable changes to the process title (#3623)
* Add proc-title-template option to control what's shown in the process title (#8397)

Redis 6.2 RC1 Released Mon Dec 14 11:50:00 IST 2020
================================================================================
Upgrade urgency LOW: This is the first Release Candidate of Redis 6.2.
Introduction to the Redis 6.2 release
=====================================
This release is the first significant Redis release managed by the core team
under the new project governance model.
Redis 6.2 includes many new commands and improvements, but no big features. It
mainly makes Redis more complete and addresses issues that have been requested
by many users frequently or for a long time.
Many of these changes were not eligible for 6.0.x for several reasons:
1. They are not backward compatible, which is always the case with new or
extended commands (that cannot be replicated to an older replica).
2. They require a longer release-candidate test cycle.
Here is a comprehensive list of changes in this release compared to 6.0.9,
each one includes the PR number that added it, so you can get more details
at https://github.com/redis/redis/pull/<number>
New commands / args:
* Add SMISMEMBER command that checks multiple members (#7615)
* Add ZMSCORE command that returns an array of scores (#7593)
* Add LMOVE and BLMOVE commands that pop and push arbitrarily (#6929)
* Add RESET command that resets client connection state (#7982)
* Add COPY command that copies keys (#7953)
* Add ZDIFF and ZDIFFSTORE commands (#7961)
* Add ZINTER and ZUNION commands (#7794)
* Add GEOSEARCH/GEOSEARCHSTORE commands for bounding box spatial queries (#8094)
* Add GET parameter to SET command, for more powerful GETSET (#7852)
* Add exclusive range query to XPENDING (#8130)
* Add exclusive range query to X[REV]RANGE (#8072)
* Add GT and LT options to ZADD for conditional score updates (#7818)
* Add CLIENT INFO and CLIENT LIST for specific ids (#8113)
* Add IDLE argument to XPENDING command (#7972)
* Add local address to CLIENT LIST, and a CLIENT KILL filter. (#7913)
* Add NOMKSTREAM option to XADD command (#7910)
* Add command introspection to Sentinel (#7940)
* Add SENTINEL MYID subcommand (#7858)
New features:
* Dump payload sanitization: prevent corrupt payload causing crashes (#7807)
Has flags to enable full O(N) validation (disabled by default).
* ACL patterns for Pub/Sub channels (#7993)
* Support ACL for Sentinel mode (#7888)
* Support getting configuration from both stdin and file at the same time (#7893)
Lets you avoid storing secrets on the disk.
New features in CLI tools:
* redis-cli RESP3 push support (#7609)
* redis-cli cluster import support source and target that require auth (#7994)
* redis-cli URIs able to provide user name in addition to password (#8048)
* redis-cli/redis-benchmark allow specifying the prefered ciphers/ciphersuites (#8005)
* redis-cli add -e option to exit with code when command execution fails (#8136)
Command behavior changes:
* EXISTS should not alter LRU (#8016)
In Redis 5.0 and 6.0 it would have touched the LRU/LFU of the key.
* OBJECT should not reveal logically expired keys (#8016)
Will now behave the same TYPE or any other non-DEBUG command.
* Improve db id range check for SELECT and MOVE (#8085)
Changes the error message text on a wrong db index.
* Modify AUTH / HELLO error message (#7648)
Changes the error message text when the user isn't found or is disabled.
* BITOPS length limited to proto_max_bulk_len rather than 512MB (#8096)
The limit is now configurable like in SETRANGE, and APPEND.
* GEORADIUS[BYMEMBER] can fail with -OOM if Redis is over the memory limit (#8107)
Other behavior changes:
* Optionally (default) fail to start if requested bind address is not available (#7936)
If you rely on Redis starting successfully even if one of the bind addresses
is not available, you'll need to tune the new config.
* Limit the main db dictionaries expansion to prevent key eviction (#7954)
In the past big dictionary rehashing could result in massive data eviction.
Now this rehashing is delayed (up to a limit), which can result in performance
loss due to hash collisions.
* CONFIG REWRITE is atomic and safer, but requires write access to the config file's folder (#7824, #8051)
This change was already present in 6.0.9, but was missing from the release
notes.
* A new incremental eviction mechanism that reduces latency on eviction spikes (#7653)
In pathological cases this can cause memory to grow uncontrolled and may require
specific tuning.
* Not resetting "save" config when Redis is started with command line arguments. (#7092)
In case you provide command line arguments without "save" and count on it
being disabled, Now the defaults "save" config will kick in.
* Update memory metrics for INFO during loading (#7690)
* When "supervised" config is enabled, it takes precedence over "daemonize". (#8036)
* Assertion and panic, print crash log without generating SIGSEGV (#7585)
* Added crash log report on SIGABRT, instead of silently exiting (#8004)
* Disable THP (Transparent Huge Pages) if enabled (#7381)
If you deliberately enabled it, you'll need to config Redis to keep it.
Bug fixes:
* Handle output buffer limits for module blocked clients (#8141)
Could result in a module sending reply to a blocked client to go beyond the
limit.
* Fix setproctitle related crashes. (#8150, #8088)
Caused various crashes on startup, mainly on Apple M1 chips or under
instrumentation.
* A module doing RM_Call could cause replicas to get nested MULTI (#8097).
* Backup/restore cluster mode keys to slots map for repl-diskless-load=swapdb (#8108)
In cluster mode with repl-diskless-load, when loading failed, slot map
wouldn't have been restored.
* Fix oom-score-adj-values range, and bug when used in config file (#8046)
Enabling setting this in the config file in a line after enabling it, would
have been buggy.
* Reset average ttl when empty databases (#8106)
Just causing misleading metric in INFO
* Disable rehash when Redis has child process (#8007)
This could have caused excessive CoW during BGSAVE, replication or AOFRW.
* Further improved ACL algorithm for picking categories (#7966)
Output of ACL GETUSER is now more similar to the one provided by ACL SETUSER.
* Fix bug with module GIL being released prematurely (#8061)
Could in theory (and rarely) cause multi-threaded modules to corrupt memory.
* Fix cluster redirect for module command with no firstkey. (#7539)
* Reduce effect of client tracking causing feedback loop in key eviction (#8100)
* Kill disk-based fork child when all replicas drop and 'save' is not enabled (#7819)
* Rewritten commands (modified for propagation) are logged as their original command (#8006)
* Fix cluster access to unaligned memory (SIGBUS on old ARM) #7958
* If diskless repl child is killed, make sure to reap the child pid (#7742)
* Broadcast a PONG message when slot's migration is over, may reduce MOVED responses (#7571)
Other improvements:
* TLS Support in redis-benchmark (#7959)
* Accelerate diskless master connections, and general re-connections (#6271)
* Run active defrag while blocked / loading (#7726)
* Performance and memory reporting improvement - sds take control of its internal fragmentation (#7875)
* Speedup cluster failover. (#7948)
Platform / toolchain support related improvements:
* Optionally (not by default) use H/W Monotonic clock for faster time sampling (#7644)
* Remove the requirements for C11 and _Atomic supporting compiler (#7707)
This would allow to more easily build and use Redis on older systems and
compilers again.
* Fix crash log registers output on ARM. (#8020)
* Raspberry build fix. (#8095)
* Setting process title support for Haiku. (#8060)
* DragonFlyBSD RSS memory sampling support. (#8023)
New configuration options:
* Enable configuring OpenSSL using the standard openssl.cnf (#8143)
* oom-score-adj-values config can now take absolute values (besides relative ones) (#8046)
* TLS: Add different client cert support. (#8076)
* Note that a few other changes listed above added their config options.
Info fields and introspection changes:
* Add INFO fields to track diskless and disk-based replication progress (#7981)
* Add INFO field for main thread cpu time, and scrape system time. (#8132)
* Add total_forks to INFO STATS (#8155)
* Add maxclients and cluster_connections to INFO CLIENTS (#7979)
* Add tracking bcast flag and client redirection in client list (#7995)
* Fixed INFO client_recent_max_input_buffer includes argv array (#8065, see #7874)
* Note that a few other changes listed above added their info fields.
Module API changes:
* Add CTX_FLAGS_DENY_BLOCKING as a unified the way to know if blocking is allowed (#8025)
* Add data type callbacks for lazy free effort, and unlink (#7912)
* Add data type callback for COPY command (#8112)
* Add callbacks for defrag support. (#8149)
* Add module event for repl-diskless-load swapdb (#8153)
Module related fixes:
* Moved RMAPI_FUNC_SUPPORTED so that it's usable (#8037)
* Improve timer accuracy (#7987)
* Allow '\0' inside of result of RM_CreateStringPrintf (#6260)
Thanks to all the users and developers who made this release possible.

# IMPORTANT: HOW TO USE REDIS GITHUB ISSUES
Github issues SHOULD ONLY BE USED to report bugs, and for DETAILED feature
requests. Everything else belongs to the Redis Google Group:
https://groups.google.com/forum/m/#!forum/Redis-db
PLEASE DO NOT POST GENERAL QUESTIONS that are not about bugs or suspected
bugs in the Github issues system. We'll be very happy to help you and provide
all the support in the mailing list.
There is also an active community of Redis users at Stack Overflow:
http://stackoverflow.com/questions/tagged/redis
# Reporting Security Bugs
*If you are reporting a security bug*, please contact the core team privately
by emailing redis@redis.io. Your report will be acknowledged by a core team
member and once the report has been reviewed you will receive a more detailed
response including next steps.
If you do not receive a reply you can escalate to the Redis Google Group,
linked above. Because this group is a public space please do not disclose the
issue in detail, only say that you are trying to reach the core team for a
security issue.
Redis follows a responsible disclosure process:
1. Reports are reviewed and analyzed privately
2. Patches are prepared for supported versions of Redis
3. Vendor lists are notified with an embargo date to reduce the public impact
4. We push a fix release and your bug can be posted publicly with credit in
release notes and the version history (and our thanks!)
Issues and pull requests for documentation belong on the redis-doc repo:
https://github.com/redis/redis-doc
# How to provide a patch for a new feature
1. If it is a major feature or a semantical change, please don't start coding
straight away: if your feature is not a conceptual fit you'll lose a lot of
time writing the code without any reason. Start by posting in the mailing list
and creating an issue at Github with the description of, exactly, what you want
to accomplish and why. Use cases are important for features to be accepted.
Here you'll see if there is consensus about your idea.
2. If in step 1 you get an acknowledgment from the project leaders, use the
following procedure to submit a patch:
a. Fork Redis on github ( http://help.github.com/fork-a-repo/ )
b. Create a topic branch (git checkout -b my_branch)
c. Push to your branch (git push origin my_branch)
d. Initiate a pull request on github ( https://help.github.com/articles/creating-a-pull-request/ )
e. Done :)
3. Keep in mind that we are very overloaded, so issues and PRs sometimes wait
for a *very* long time. However this is not lack of interest, as the project
gets more and more users, we find ourselves in a constant need to prioritize
certain issues/PRs over others. If you think your issue/PR is very important
try to popularize it, have other users commenting and sharing their point of
view and so forth. This helps.
4. For minor fixes just open a pull request on Github.
Thanks!

2010-05-06 AOF writes are now accumulated into a buffer and flushed into disk just before re-entering the event loop. A lot less writes but still this guarantees that AOF is written before the client gets a positive reply about a write operation, as no reply is trasnmitted before re-entering into the event loop. (antirez)

[Note: this is the Redis manifesto, for general information about
installing and running Redis read the README file instead.]
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 - We believe in code efficiency. Computers get faster and faster, yet we
believe that abusing computing capabilities is not wise: the amount of
operations you can do for a given amount of energy remains anyway a
significant parameter: it allows to do more with less computers and, at
the same time, having a smaller environmental impact. Similarly Redis is
able to "scale down" to smaller devices. It is perfectly usable in a
Raspberry Pi and other small ARM based computers. Faster code having
just the layers of abstractions that are really needed will also result,
often, in more predictable performances. We think likewise about memory
usage, one of the fundamental goals of the Redis project is to
incrementally build more and more memory efficient data structures, so that
problems that were not approachable in RAM in the past will be perfectly
fine to handle in the future.
5 - 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.
6 - 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. Complexity is also a form of lock-in: code that is
very hard to understand cannot be modified by users in an independent way
regardless of the license. One of the main Redis goals is to remain
understandable, enough for a single programmer to have a clear idea of how
it works in detail just reading the source code for a couple of weeks.
7 - Threading is not a silver bullet. Instead of making Redis threaded we
believe on the idea of an efficient (mostly) single threaded Redis core.
Multiple of such cores, that may run in the same computer or may run
in multiple computers, are abstracted away as a single big system by
higher order protocols and features: Redis Cluster and the upcoming
Redis Proxy are our main goals. A shared nothing approach is not just
much simpler (see the previous point in this document), is also optimal
in NUMA systems. In the specific case of Redis it allows for each instance
to have a more limited amount of data, making the Redis persist-by-fork
approach more sounding. In the future we may explore parallelism only for
I/O, which is the low hanging fruit: minimal complexity could provide an
improved single process experience.
8 - 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
trade-offs to the user.
9 - 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.
10 - All the above points are put together in what we call opportunistic
programming: trying to get the most for the user with minimal increases
in complexity (hanging fruits). Solve 95% of the problem with 5% of the
code when it is acceptable. Avoid a fixed schedule but follow the flow of
user requests, inspiration, Redis internal readiness for certain features
(sometimes many past changes reach a critical point making a previously
complex feature very easy to obtain).

Where to find complete Redis documentation?
-------------------------------------------
This README is just a fast "quick start" document. You can find more detailed
documentation here:
1) http://code.google.com/p/redis
2) Check the 'doc' directory. doc/README.html is a good starting point :)
Building Redis
--------------
It is as simple as:
% make
Redis is just a single binary, but if you want to install it you can use
the "make install" target that will copy the binary in /usr/local/bin
for default.
You can run a 32 bit Redis binary using:
% make 32bit
After you build Redis is a good idea to test it, using:
% make test
Running Redis
-------------
To run Redis with the default configuration just type:
% ./redis-server
If you want to provide your redis.conf, you have to run it using an additional
parameter (the path of the configuration file):
% ./redis-server /path/to/redis.conf
Playing with Redis
------------------
You can use redis-cli to play with Redis. Start a redis-server instance,
then in another terminal try the following:
% ./redis-cli
redis> ping
PONG
redis> set foo bar
OK
redis> get foo
"bar"
redis> incr mycounter
(integer) 1
redis> incr mycounter
(integer) 2
redis>
You can find the list of all the available commands here:

This README is just a fast *quick start* document. You can find more detailed documentation at [redis.io](https://redis.io).
What is Redis?
--------------
Redis is often referred to as a *data structures* server. What this means is that Redis provides access to mutable data structures via a set of commands, which are sent using a *server-client* model with TCP sockets and a simple protocol. So different processes can query and modify the same data structures in a shared way.
Data structures implemented into Redis have a few special properties:
* Redis cares to store them on disk, even if they are always served and modified into the server memory. This means that Redis is fast, but that it is also non-volatile.
* The implementation of data structures emphasizes memory efficiency, so data structures inside Redis will likely use less memory compared to the same data structure modelled using a high-level programming language.
* Redis offers a number of features that are natural to find in a database, like replication, tunable levels of durability, clustering, and high availability.
Another good example is to think of Redis as a more complex version of memcached, where the operations are not just SETs and GETs, but operations that work with complex data types like Lists, Sets, ordered data structures, and so forth.
If you want to know more, this is a list of selected starting points:
* Introduction to Redis data types. http://redis.io/topics/data-types-intro
* Try Redis directly inside your browser. http://try.redis.io
* The full list of Redis commands. http://redis.io/commands
* There is much more inside the official Redis documentation. http://redis.io/documentation
Building Redis
--------------
Redis can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD.
We support big endian and little endian architectures, and both 32 bit
and 64 bit systems.
It may compile on Solaris derived systems (for instance SmartOS) but our
support for this platform is *best effort* and Redis is not guaranteed to
work as well as in Linux, OSX, and \*BSD.
It is as simple as:
% make
To build with TLS support, you'll need OpenSSL development libraries (e.g.
libssl-dev on Debian/Ubuntu) and run:
% make BUILD_TLS=yes
To build with systemd support, you'll need systemd development libraries (such
as libsystemd-dev on Debian/Ubuntu or systemd-devel on CentOS) and run:
% make USE_SYSTEMD=yes
To append a suffix to Redis program names, use:
% make PROG_SUFFIX="-alt"
You can run a 32 bit Redis binary using:
% make 32bit
After building Redis, it is a good idea to test it using:
% make test
If TLS is built, running the tests with TLS enabled (you will need `tcl-tls`
installed):
% ./utils/gen-test-certs.sh
% ./runtest --tls
Fixing build problems with dependencies or cached build options
---------
Redis has some dependencies which are included in the `deps` directory.
`make` does not automatically rebuild dependencies even if something in
the source code of dependencies changes.
When you update the source code with `git pull` or when code inside the
dependencies tree is modified in any other way, make sure to use the following
command in order to really clean everything and rebuild from scratch:
make distclean
This will clean: jemalloc, lua, hiredis, linenoise.
Also if you force certain build options like 32bit target, no C compiler
optimizations (for debugging purposes), and other similar build time options,
those options are cached indefinitely until you issue a `make distclean`
command.
Fixing problems building 32 bit binaries
---------
If after building Redis with a 32 bit target you need to rebuild it
with a 64 bit target, or the other way around, you need to perform a
`make distclean` in the root directory of the Redis distribution.
In case of build errors when trying to build a 32 bit binary of Redis, try
the following steps:
* Install the package libc6-dev-i386 (also try g++-multilib).
* Try using the following command line instead of `make 32bit`:
`make CFLAGS="-m32 -march=native" LDFLAGS="-m32"`
Allocator
---------
Selecting a non-default memory allocator when building Redis is done by setting
the `MALLOC` environment variable. Redis is compiled and linked against libc
malloc by default, with the exception of jemalloc being the default on Linux
systems. This default was picked because jemalloc has proven to have fewer
fragmentation problems than libc malloc.
To force compiling against libc malloc, use:
% make MALLOC=libc
To compile against jemalloc on Mac OS X systems, use:
% make MALLOC=jemalloc
Monotonic clock
---------------
By default, Redis will build using the POSIX clock_gettime function as the
monotonic clock source. On most modern systems, the internal processor clock
can be used to improve performance. Cautions can be found here:
http://oliveryang.net/2015/09/pitfalls-of-TSC-usage/
To build with support for the processor's internal instruction clock, use:
% make CFLAGS="-DUSE_PROCESSOR_CLOCK"
Verbose build
-------------
Redis will build with a user-friendly colorized output by default.
If you want to see a more verbose output, use the following:
% make V=1
Running Redis
-------------
To run Redis with the default configuration, just type:
% cd src
% ./redis-server
If you want to provide your redis.conf, you have to run it using an additional
parameter (the path of the configuration file):
% cd src
% ./redis-server /path/to/redis.conf
It is possible to alter the Redis configuration by passing parameters directly
as options using the command line. Examples:
% ./redis-server --port 9999 --replicaof 127.0.0.1 6379
% ./redis-server /etc/redis/6379.conf --loglevel debug
All the options in redis.conf are also supported as options using the command
line, with exactly the same name.
Running Redis with TLS:
------------------
Please consult the [TLS.md](TLS.md) file for more information on
how to use Redis with TLS.
Playing with Redis
------------------
You can use redis-cli to play with Redis. Start a redis-server instance,
then in another terminal try the following:
% cd src
% ./redis-cli
redis> ping
PONG
redis> set foo bar
OK
redis> get foo
"bar"
redis> incr mycounter
(integer) 1
redis> incr mycounter
(integer) 2
redis>
You can find the list of all the available commands at http://redis.io/commands.
Installing Redis
-----------------
In order to install Redis binaries into /usr/local/bin, just use:
% make install
You can use `make PREFIX=/some/other/directory install` if you wish to use a
different destination.
Make install will just install binaries in your system, but will not configure
init scripts and configuration files in the appropriate place. This is not
needed if you just want to play a bit with Redis, but if you are installing
it the proper way for a production system, we have a script that does this
for Ubuntu and Debian systems:
% cd utils
% ./install_server.sh
_Note_: `install_server.sh` will not work on Mac OSX; it is built for Linux only.
The script will ask you a few questions and will setup everything you need
to run Redis properly as a background daemon that will start again on
system reboots.
You'll be able to stop and start Redis using the script named
`/etc/init.d/redis_<portnumber>`, for instance `/etc/init.d/redis_6379`.

Redis internals
===
If you are reading this README you are likely in front of a Github page
or you just untarred the Redis distribution tar ball. In both the cases
you are basically one step away from the source code, so here we explain
the Redis source code layout, what is in each file as a general idea, the
most important functions and structures inside the Redis server and so forth.
We keep all the discussion at a high level without digging into the details
since this document would be huge otherwise and our code base changes
continuously, but a general idea should be a good starting point to
understand more. Moreover most of the code is heavily commented and easy
to follow.
Source code layout
---
The Redis root directory just contains this README, the Makefile which
calls the real Makefile inside the `src` directory and an example
configuration for Redis and Sentinel. You can find a few shell
scripts that are used in order to execute the Redis, Redis Cluster and
Redis Sentinel unit tests, which are implemented inside the `tests`
directory.
Inside the root are the following important directories:
* `src`: contains the Redis implementation, written in C.
* `tests`: contains the unit tests, implemented in Tcl.
* `deps`: contains libraries Redis uses. Everything needed to compile Redis is inside this directory; your system just needs to provide `libc`, a POSIX compatible interface and a C compiler. Notably `deps` contains a copy of `jemalloc`, which is the default allocator of Redis under Linux. Note that under `deps` there are also things which started with the Redis project, but for which the main repository is not `redis/redis`.
There are a few more directories but they are not very important for our goals
here. We'll focus mostly on `src`, where the Redis implementation is contained,
exploring what there is inside each file. The order in which files are
exposed is the logical one to follow in order to disclose different layers
of complexity incrementally.
Note: lately Redis was refactored quite a bit. Function names and file
names have been changed, so you may find that this documentation reflects the
`unstable` branch more closely. For instance, in Redis 3.0 the `server.c`
and `server.h` files were named `redis.c` and `redis.h`. However the overall
structure is the same. Keep in mind that all the new developments and pull
requests should be performed against the `unstable` branch.
server.h
---
The simplest way to understand how a program works is to understand the
data structures it uses. So we'll start from the main header file of
Redis, which is `server.h`.
All the server configuration and in general all the shared state is
defined in a global structure called `server`, of type `struct redisServer`.
A few important fields in this structure are:
* `server.db` is an array of Redis databases, where data is stored.
* `server.commands` is the command table.
* `server.clients` is a linked list of clients connected to the server.
* `server.master` is a special client, the master, if the instance is a replica.
There are tons of other fields. Most fields are commented directly inside
the structure definition.
Another important Redis data structure is the one defining a client.
In the past it was called `redisClient`, now just `client`. The structure
has many fields, here we'll just show the main ones:
struct client {
int fd;
sds querybuf;
int argc;
robj **argv;
redisDb *db;
int flags;
list *reply;
char buf[PROTO_REPLY_CHUNK_BYTES];
... many other fields ...
}
The client structure defines a *connected client*:
* The `fd` field is the client socket file descriptor.
* `argc` and `argv` are populated with the command the client is executing, so that functions implementing a given Redis command can read the arguments.
* `querybuf` accumulates the requests from the client, which are parsed by the Redis server according to the Redis protocol and executed by calling the implementations of the commands the client is executing.
* `reply` and `buf` are dynamic and static buffers that accumulate the replies the server sends to the client. These buffers are incrementally written to the socket as soon as the file descriptor is writeable.
As you can see in the client structure above, arguments in a command
are described as `robj` structures. The following is the full `robj`
structure, which defines a *Redis object*:
typedef struct redisObject {
unsigned type:4;
unsigned encoding:4;
unsigned lru:LRU_BITS; /* lru time (relative to server.lruclock) */
int refcount;
void *ptr;
} robj;
Basically this structure can represent all the basic Redis data types like
strings, lists, sets, sorted sets and so forth. The interesting thing is that
it has a `type` field, so that it is possible to know what type a given
object has, and a `refcount`, so that the same object can be referenced
in multiple places without allocating it multiple times. Finally the `ptr`
field points to the actual representation of the object, which might vary
even for the same type, depending on the `encoding` used.
Redis objects are used extensively in the Redis internals, however in order
to avoid the overhead of indirect accesses, recently in many places
we just use plain dynamic strings not wrapped inside a Redis object.
server.c
---
This is the entry point of the Redis server, where the `main()` function
is defined. The following are the most important steps in order to startup
the Redis server.
* `initServerConfig()` sets up the default values of the `server` structure.
* `initServer()` allocates the data structures needed to operate, setup the listening socket, and so forth.
* `aeMain()` starts the event loop which listens for new connections.
There are two special functions called periodically by the event loop:
1. `serverCron()` is called periodically (according to `server.hz` frequency), and performs tasks that must be performed from time to time, like checking for timed out clients.
2. `beforeSleep()` is called every time the event loop fired, Redis served a few requests, and is returning back into the event loop.
Inside server.c you can find code that handles other vital things of the Redis server:
* `call()` is used in order to call a given command in the context of a given client.
* `activeExpireCycle()` handles eviction of keys with a time to live set via the `EXPIRE` command.
* `performEvictions()` is called when a new write command should be performed but Redis is out of memory according to the `maxmemory` directive.
* The global variable `redisCommandTable` defines all the Redis commands, specifying the name of the command, the function implementing the command, the number of arguments required, and other properties of each command.
networking.c
---
This file defines all the I/O functions with clients, masters and replicas
(which in Redis are just special clients):
* `createClient()` allocates and initializes a new client.
* the `addReply*()` family of functions are used by command implementations in order to append data to the client structure, that will be transmitted to the client as a reply for a given command executed.
* `writeToClient()` transmits the data pending in the output buffers to the client and is called by the *writable event handler* `sendReplyToClient()`.
* `readQueryFromClient()` is the *readable event handler* and accumulates data read from the client into the query buffer.
* `processInputBuffer()` is the entry point in order to parse the client query buffer according to the Redis protocol. Once commands are ready to be processed, it calls `processCommand()` which is defined inside `server.c` in order to actually execute the command.
* `freeClient()` deallocates, disconnects and removes a client.
aof.c and rdb.c
---
As you can guess from the names, these files implement the RDB and AOF
persistence for Redis. Redis uses a persistence model based on the `fork()`
system call in order to create a thread with the same (shared) memory
content of the main Redis thread. This secondary thread dumps the content
of the memory on disk. This is used by `rdb.c` to create the snapshots
on disk and by `aof.c` in order to perform the AOF rewrite when the
append only file gets too big.
The implementation inside `aof.c` has additional functions in order to
implement an API that allows commands to append new commands into the AOF
file as clients execute them.
The `call()` function defined inside `server.c` is responsible for calling
the functions that in turn will write the commands into the AOF.
db.c
---
Certain Redis commands operate on specific data types; others are general.
Examples of generic commands are `DEL` and `EXPIRE`. They operate on keys
and not on their values specifically. All those generic commands are
defined inside `db.c`.
Moreover `db.c` implements an API in order to perform certain operations
on the Redis dataset without directly accessing the internal data structures.
The most important functions inside `db.c` which are used in many command
implementations are the following:
* `lookupKeyRead()` and `lookupKeyWrite()` are used in order to get a pointer to the value associated to a given key, or `NULL` if the key does not exist.
* `dbAdd()` and its higher level counterpart `setKey()` create a new key in a Redis database.
* `dbDelete()` removes a key and its associated value.
* `emptyDb()` removes an entire single database or all the databases defined.
The rest of the file implements the generic commands exposed to the client.
object.c
---
The `robj` structure defining Redis objects was already described. Inside
`object.c` there are all the functions that operate with Redis objects at
a basic level, like functions to allocate new objects, handle the reference
counting and so forth. Notable functions inside this file:
* `incrRefCount()` and `decrRefCount()` are used in order to increment or decrement an object reference count. When it drops to 0 the object is finally freed.
* `createObject()` allocates a new object. There are also specialized functions to allocate string objects having a specific content, like `createStringObjectFromLongLong()` and similar functions.
This file also implements the `OBJECT` command.
replication.c
---
This is one of the most complex files inside Redis, it is recommended to
approach it only after getting a bit familiar with the rest of the code base.
In this file there is the implementation of both the master and replica role
of Redis.
One of the most important functions inside this file is `replicationFeedSlaves()` that writes commands to the clients representing replica instances connected
to our master, so that the replicas can get the writes performed by the clients:
this way their data set will remain synchronized with the one in the master.
This file also implements both the `SYNC` and `PSYNC` commands that are
used in order to perform the first synchronization between masters and
replicas, or to continue the replication after a disconnection.
Other C files
---
* `t_hash.c`, `t_list.c`, `t_set.c`, `t_string.c`, `t_zset.c` and `t_stream.c` contains the implementation of the Redis data types. They implement both an API to access a given data type, and the client command implementations for these data types.
* `ae.c` implements the Redis event loop, it's a self contained library which is simple to read and understand.
* `sds.c` is the Redis string library, check http://github.com/antirez/sds for more information.
* `anet.c` is a library to use POSIX networking in a simpler way compared to the raw interface exposed by the kernel.
* `dict.c` is an implementation of a non-blocking hash table which rehashes incrementally.
* `scripting.c` implements Lua scripting. It is completely self-contained and isolated from the rest of the Redis implementation and is simple enough to understand if you are familiar with the Lua API.
* `cluster.c` implements the Redis Cluster. Probably a good read only after being very familiar with the rest of the Redis code base. If you want to read `cluster.c` make sure to read the [Redis Cluster specification][3].
[3]: http://redis.io/topics/cluster-spec
Anatomy of a Redis command
---
All the Redis commands are defined in the following way:
void foobarCommand(client *c) {
printf("%s",c->argv[1]->ptr); /* Do something with the argument. */
addReply(c,shared.ok); /* Reply something to the client. */
}
The command is then referenced inside `server.c` in the command table:
{"foobar",foobarCommand,2,"rtF",0,NULL,0,0,0,0,0},
In the above example `2` is the number of arguments the command takes,
while `"rtF"` are the command flags, as documented in the command table
top comment inside `server.c`.
After the command operates in some way, it returns a reply to the client,
usually using `addReply()` or a similar function defined inside `networking.c`.
There are tons of command implementations inside the Redis source code
that can serve as examples of actual commands implementations. Writing
a few toy commands can be a good exercise to get familiar with the code base.
There are also many other files not described here, but it is useless to
cover everything. We just want to help you with the first steps.
Eventually you'll find your way inside the Redis code base :-)
Enjoy!

TLS Support
===========
Getting Started
---------------
### Building
To build with TLS support you'll need OpenSSL development libraries (e.g.
libssl-dev on Debian/Ubuntu).
Run `make BUILD_TLS=yes`.
### Tests
To run Redis test suite with TLS, you'll need TLS support for TCL (i.e.
`tcl-tls` package on Debian/Ubuntu).
1. Run `./utils/gen-test-certs.sh` to generate a root CA and a server
certificate.
2. Run `./runtest --tls` or `./runtest-cluster --tls` to run Redis and Redis
Cluster tests in TLS mode.
### Running manually
To manually run a Redis server with TLS mode (assuming `gen-test-certs.sh` was
invoked so sample certificates/keys are available):
./src/redis-server --tls-port 6379 --port 0 \
--tls-cert-file ./tests/tls/redis.crt \
--tls-key-file ./tests/tls/redis.key \
--tls-ca-cert-file ./tests/tls/ca.crt
To connect to this Redis server with `redis-cli`:
./src/redis-cli --tls \
--cert ./tests/tls/redis.crt \
--key ./tests/tls/redis.key \
--cacert ./tests/tls/ca.crt
This will disable TCP and enable TLS on port 6379. It's also possible to have
both TCP and TLS available, but you'll need to assign different ports.
To make a Replica connect to the master using TLS, use `--tls-replication yes`,
and to make Redis Cluster use TLS across nodes use `--tls-cluster yes`.
Connections
-----------
All socket operations now go through a connection abstraction layer that hides
I/O and read/write event handling from the caller.
**Multi-threading I/O is not currently supported for TLS**, as a TLS connection
needs to do its own manipulation of AE events which is not thread safe. The
solution is probably to manage independent AE loops for I/O threads and longer
term association of connections with threads. This may potentially improve
overall performance as well.
Sync IO for TLS is currently implemented in a hackish way, i.e. making the
socket blocking and configuring socket-level timeout. This means the timeout
value may not be so accurate, and there would be a lot of syscall overhead.
However I believe that getting rid of syncio completely in favor of pure async
work is probably a better move than trying to fix that. For replication it would
probably not be so hard. For cluster keys migration it might be more difficult,
but there are probably other good reasons to improve that part anyway.
To-Do List
----------
- [ ] redis-benchmark support. The current implementation is a mix of using
hiredis for parsing and basic networking (establishing connections), but
directly manipulating sockets for most actions. This will need to be cleaned
up for proper TLS support. The best approach is probably to migrate to hiredis
async mode.
- [ ] redis-cli `--slave` and `--rdb` support.
Multi-port
----------
Consider the implications of allowing TLS to be configured on a separate port,
making Redis listening on multiple ports:
1. Startup banner port notification
2. Proctitle
3. How slaves announce themselves
4. Cluster bus port calculation

Redis TODO and Roadmap
----------------------
VERSION 2.2 TODO (Optimizations and latency)
============================================
* Lower the CPU usage.
* Lower the RAM usage everywhere possible.
* Specially encoded Sets (like Hashes).
* Implement an UDP interface for low-latency operations.
* What about a special coding that is about storing the "rdb" serialized format instead of the actual value? This can be used when we have LRU in order to super-compress data into memory, for data not accessed frequetly. It's a VM-alike strategy but fully in memory, may reduce the space to hold some dataset in an impressive way. Trivial to implement.
* Another idea: LRU does not need to be super precise right? Maybe it's a good idea to just put into the skiplist implementing the LRU just the pointer to the key without evne incr/decr business, nor the need to remove the pointer when the key is deleted. There is to think more about that.
VERSION 2.x TODO
================
* BRPOPLPUSH
* Save dataset / fsync() on SIGTERM
* Change the implementation of ZCOUNT to use the augmented skiplist in order to be much faster.
Virtual Memory optimizations:
* Use multiple open FDs against the VM file, one for thread.
* Check what happens performance-wise if instead of creating threads again and again the same threads are reused forever. Note: this requires a way to disable this clients in the child, but waiting for empty new jobs queue can be enough.
* Implement LEN, PEEK, POKE, SETBIT, GETBIT
OTHER IMPORTANT THINGS THAT WILL BE ADDED BUT I'M NOT SURE WHEN
===============================================================
BIG ONES:
* Specially encoded memory-saving integer sets.
* A command to export a JSON dump (there should be mostly working patch needing major reworking).
* Specially encoded sets of integers (this includes a big refactoring providing an higher level layer for Sets manipulation)
SMALL ONES:
* If sizeof(double) == sizeof(void*) we could store the double value of sorted sets directly in place of the pointer instead of allocating it in the heap.
* Delete on writes against expire policy should only happen after argument parsing for commands doing their own arg parsing stuff.
* Give errors when incrementing a key that does not look like an integer, when providing as a sorted set score something can't be parsed as a double, and so forth.
* MSADD (n keys) (n values). See this thread in the Redis google group: http://groups.google.com/group/redis-db/browse_thread/thread/e766d84eb375cd41
* Don't save empty lists / sets / zsets on disk with snapshotting.
* Remove keys when a list / set / zset reaches length of 0.
* An option to exec a command slave-side if the master connection is lost: even cooler: if the script returns "0" the slave elects itself as master, otherwise continue trying to reconnect.
* PING the master from time to time to check if it's gone.
THE "MAYBE" TODO LIST: things that may or may not get implemented
=================================================================
Most of this can be seen just as proposals, the fact they are in this list
it's not a guarantee they'll ever get implemented ;)
* Move dict.c from hash table to skip list, in order to avoid the blocking resize operation needed for the hash table.
* FORK command (fork()s executing the commands received by the current
client in the new process). Hint: large SORTs can use more cores,
copy-on-write will avoid memory problems.
* DUP command? DUP srckey dstkey, creates an exact clone of srckey value in dstkey.
* 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.
* LOCK / TRYLOCK / UNLOCK as described many times in the google group
* Replication automated tests
* Byte Array type (BA prefixed commands): BASETBIT BAGETBIT BASETU8 U16 U32 U64 S8 S16 S32 S64, ability to atomically INCRBY all the base types. BARANGE to get a range of bytes as a bulk value, BASETRANGE to set a range of bytes.
* zmalloc() should avoid to add a private header for archs where there is some other kind of libc-specific way to get the size of a malloced block. Already done for Mac OS X.
* Read-only mode.
* Pattern-matching replication.
* Add an option to relax the delete-expiring-keys-on-write semantic *denying* replication and AOF when this is on? Can be handy sometimes, when using Redis for non persistent state, but can create problems. For instance should rename and move also "move" the timeouts? How does this affect other commands?
* Multiple BY in SORT.

This directory contains all Redis dependencies, except for the libc that
should be provided by the operating system.
* **Jemalloc** is our memory allocator, used as replacement for libc malloc on Linux by default. It has good performances and excellent fragmentation behavior. This component is upgraded from time to time.
* **hiredis** is the official C client library for Redis. It is used by redis-cli, redis-benchmark and Redis Sentinel. It is part of the Redis official ecosystem but is developed externally from the Redis repository, so we just upgrade it as needed.
* **linenoise** is a readline replacement. It is developed by the same authors of Redis but is managed as a separated project and updated as needed.
* **lua** is Lua 5.1 with minor changes for security and additional libraries.
How to upgrade the above dependencies
===
Jemalloc
---
Jemalloc is modified with changes that allow us to implement the Redis
active defragmentation logic. However this feature of Redis is not mandatory
and Redis is able to understand if the Jemalloc version it is compiled
against supports such Redis-specific modifications. So in theory, if you
are not interested in the active defragmentation, you can replace Jemalloc
just following these steps:
1. Remove the jemalloc directory.
2. Substitute it with the new jemalloc source tree.
3. Edit the Makefile located in the same directory as the README you are
reading, and change the --with-version in the Jemalloc configure script
options with the version you are using. This is required because otherwise
Jemalloc configuration script is broken and will not work nested in another
git repository.
However note that we change Jemalloc settings via the `configure` script of Jemalloc using the `--with-lg-quantum` option, setting it to the value of 3 instead of 4. This provides us with more size classes that better suit the Redis data structures, in order to gain memory efficiency.
If you want to upgrade Jemalloc while also providing support for
active defragmentation, in addition to the above steps you need to perform
the following additional steps:
5. In Jemalloc tree, file `include/jemalloc/jemalloc_macros.h.in`, make sure
to add `#define JEMALLOC_FRAG_HINT`.
6. Implement the function `je_get_defrag_hint()` inside `src/jemalloc.c`. You
can see how it is implemented in the current Jemalloc source tree shipped
with Redis, and rewrite it according to the new Jemalloc internals, if they
changed, otherwise you could just copy the old implementation if you are
upgrading just to a similar version of Jemalloc.
Hiredis
---
Hiredis uses the SDS string library, that must be the same version used inside Redis itself. Hiredis is also very critical for Sentinel. Historically Redis often used forked versions of hiredis in a way or the other. In order to upgrade it is advised to take a lot of care:
1. Check with diff if hiredis API changed and what impact it could have in Redis.
2. Make sure that the SDS library inside Hiredis and inside Redis are compatible.
3. After the upgrade, run the Redis Sentinel test.
4. Check manually that redis-cli and redis-benchmark behave as expected, since we have no tests for CLI utilities currently.
Linenoise
---
Linenoise is rarely upgraded as needed. The upgrade process is trivial since
Redis uses a non modified version of linenoise, so to upgrade just do the
following:
1. Remove the linenoise directory.
2. Substitute it with the new linenoise source tree.
Lua
---
We use Lua 5.1 and no upgrade is planned currently, since we don't want to break
Lua scripts for new Lua features: in the context of Redis Lua scripts the
capabilities of 5.1 are usually more than enough, the release is rock solid,
and we definitely don't want to break old scripts.
So upgrading of Lua is up to the Redis project maintainers and should be a
manual procedure performed by taking a diff between the different versions.
Currently we have at least the following differences between official Lua 5.1
and our version:
1. Makefile is modified to allow a different compiler than GCC.
2. We have the implementation source code, and directly link to the following external libraries: `lua_cjson.o`, `lua_struct.o`, `lua_cmsgpack.o` and `lua_bit.o`.
3. There is a security fix in `ldo.c`, line 498: The check for `LUA_SIGNATURE[0]` is removed in order to avoid direct bytecode execution.

Creative Commons Legal Code
CC0 1.0 Universal
CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
HEREUNDER.
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to
this CC0 or use of the Work.

## [1.0.0](https://github.com/redis/hiredis/tree/v1.0.0) - (2020-08-03)
Announcing Hiredis v1.0.0, which adds support for RESP3, SSL connections, allocator injection, and better Windows support! :tada:
_A big thanks to everyone who helped with this release. The following list includes everyone who contributed at least five lines, sorted by lines contributed._ :sparkling_heart:

[Full Changelog](https://github.com/redis/hiredis/compare/v0.14.1...v1.0.0)
**BREAKING CHANGES**:
* `redisOptions` now has two timeout fields. One for connecting, and one for commands. If you're presently using `options->timeout` you will need to change it to use `options->connect_timeout`. (See [example](https://github.com/redis/hiredis/commit/38b5ae543f5c99eb4ccabbe277770fc6bc81226f#diff-86ba39d37aa829c8c82624cce4f049fbL36))
* Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now protocol errors. This is consistent
with the RESP specification. On 32-bit platforms, the upper bound is lowered to `SIZE_MAX`.
* `redisReplyObjectFunctions.createArray` now takes `size_t` for its length parameter.
**New features:**
- Support for RESP3

\* *This Changelog was automatically generated by [github_changelog_generator](https://github.com/github-changelog-generator/github-changelog-generator)*
## [1.0.0-rc1](https://github.com/redis/hiredis/tree/v1.0.0-rc1) - (2020-07-29)
_Note: There were no changes to code between v1.0.0-rc1 and v1.0.0 so see v1.0.0 for changelog_
### 0.14.1 (2020-03-13)
* Adds safe allocation wrappers (CVE-2020-7105, #747, #752) (Michael Grunder)
### 0.14.0 (2018-09-25)
**BREAKING CHANGES**:
* Change `redisReply.len` to `size_t`, as it denotes the the size of a string
User code should compare this to `size_t` values as well.
If it was used to compare to other values, casting might be necessary or can be removed, if casting was applied before.
* Make string2ll static to fix conflict with Redis (Tom Lee [c3188b])
* Use -dynamiclib instead of -shared for OSX (Ryan Schmidt [a65537])
* Use string2ll from Redis w/added tests (Michael Grunder [7bef04, 60f622])
* Makefile - OSX compilation fixes (Ryan Schmidt [881fcb, 0e9af8])
* Remove redundant NULL checks (Justin Brewer [54acc8, 58e6b8])
* Fix bulk and multi-bulk length truncation (Justin Brewer [109197])
* Fix SIGSEGV in OpenBSD by checking for NULL before calling freeaddrinfo (Justin Brewer [546d94])
* Several POSIX compatibility fixes (Justin Brewer [bbeab8, 49bbaa, d1c1b6])
* Makefile - Compatibility fixes (Dimitri Vorobiev [3238cf, 12a9d1])
* Makefile - Fix make install on FreeBSD (Zach Shipko [a2ef2b])
* Makefile - don't assume $(INSTALL) is cp (Igor Gnatenko [725a96])
* Separate side-effect causing function from assert and small cleanup (amallia [b46413, 3c3234])
* Don't send negative values to `__redisAsyncCommand` (Frederik Deweerdt [706129])
* Fix leak if setsockopt fails (Frederik Deweerdt [e21c9c])
* Fix libevent leak (zfz [515228])
* Clean up GCC warning (Ichito Nagata [2ec774])
* Keep track of errno in `__redisSetErrorFromErrno()` as snprintf may use it (Jin Qing [25cd88])
* Solaris compilation fix (Donald Whyte [41b07d])
* Reorder linker arguments when building examples (Tustfarm-heart [06eedd])
* Keep track of subscriptions in case of rapid subscribe/unsubscribe (Hyungjin Kim [073dc8, be76c5, d46999])
* libuv use after free fix (Paul Scott [cbb956])
* Properly close socket fd on reconnect attempt (WSL [64d1ec])
* Skip valgrind in OSX tests (Jan-Erik Rediger [9deb78])
* Various updates for Travis testing OSX (Ted Nyman [fa3774, 16a459, bc0ea5])
* Update libevent (Chris Xin [386802])
* Change sds.h for building in C++ projects (Ali Volkan ATLI [f5b32e])
* Use proper format specifier in redisFormatSdsCommandArgv (Paulino Huerta, Jan-Erik Rediger [360a06, 8655a6])
* Better handling of NULL reply in example code (Jan-Erik Rediger [1b8ed3])
* Prevent overflow when formatting an error (Jan-Erik Rediger [0335cb])
* Compatibility fix for strerror_r (Tom Lee [bb1747])
* Properly detect integer parse/overflow errors (Justin Brewer [93421f])
* Adds CI for Windows and cygwin fixes (owent, [6c53d6, 6c3e40])
* Catch a buffer overflow when formatting the error message
* Import latest upstream sds. This breaks applications that are linked against the old hiredis v0.13
* Fix warnings, when compiled with -Wshadow
* Make hiredis compile in Cygwin on Windows, now CI-tested
* Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now
protocol errors. This is consistent with the RESP specification. On 32-bit
platforms, the upper bound is lowered to `SIZE_MAX`.
* Remove backwards compatibility macro's
This removes the following old function aliases, use the new name now:
| Old | New |
| --------------------------- | ---------------------- |
| redisReplyReaderCreate | redisReaderCreate |
| redisReplyReaderCreate | redisReaderCreate |
| redisReplyReaderFree | redisReaderFree |
| redisReplyReaderFeed | redisReaderFeed |
| redisReplyReaderGetReply | redisReaderGetReply |
| redisReplyReaderSetPrivdata | redisReaderSetPrivdata |
| redisReplyReaderGetObject | redisReaderGetObject |
| redisReplyReaderGetError | redisReaderGetError |
* The `DEBUG` variable in the Makefile was renamed to `DEBUG_FLAGS`
Previously it broke some builds for people that had `DEBUG` set to some arbitrary value,
due to debugging other software.
By renaming we avoid unintentional name clashes.
Simply rename `DEBUG` to `DEBUG_FLAGS` in your environment to make it working again.
### 0.13.3 (2015-09-16)
* Revert "Clear `REDIS_CONNECTED` flag when connection is closed".
* Make tests pass on FreeBSD (Thanks, Giacomo Olgeni)
If the `REDIS_CONNECTED` flag is cleared,
the async onDisconnect callback function will never be called.
This causes problems as the disconnect is never reported back to the user.
### 0.13.2 (2015-08-25)
* Prevent crash on pending replies in async code (Thanks, @switch-st)
* Clear `REDIS_CONNECTED` flag when connection is closed (Thanks, Jerry Jacobs)
* Add MacOS X addapter (Thanks, @dizzus)
* Add Qt adapter (Thanks, Pietro Cerutti)
* Add Ivykis adapter (Thanks, Gergely Nagy)
All adapters are provided as is and are only tested where possible.
### 0.13.1 (2015-05-03)
This is a bug fix release.
The new `reconnect` method introduced new struct members, which clashed with pre-defined names in pre-C99 code.
Another commit forced C99 compilation just to make it work, but of course this is not desirable for outside projects.
Other non-C99 code can now use hiredis as usual again.
Sorry for the inconvenience.
* Fix memory leak in async reply handling (Salvatore Sanfilippo)
* Rename struct member to avoid name clash with pre-c99 code (Alex Balashov, ncopa)
### 0.13.0 (2015-04-16)
This release adds a minimal Windows compatibility layer.
The parser, standalone since v0.12.0, can now be compiled on Windows
(and thus used in other client libraries as well)
* Windows compatibility layer for parser code (tzickel)
* Properly escape data printed to PKGCONF file (Dan Skorupski)
* Fix tests when assert() undefined (Keith Bennett, Matt Stancliff)
* Implement a reconnect method for the client context, this changes the structure of `redisContext` (Aaron Bedra)
### 0.12.1 (2015-01-26)
* Fix `make install`: DESTDIR support, install all required files, install PKGCONF in proper location
* Fix `make test` as 32 bit build on 64 bit platform
### 0.12.0 (2015-01-22)
* Add optional KeepAlive support
* Try again on EINTR errors
* Add libuv adapter
* Add IPv6 support
* Remove possibility of multiple close on same fd
* Add ability to bind source address on connect
* Add redisConnectFd() and redisFreeKeepFd()
* Fix getaddrinfo() memory leak
* Free string if it is unused (fixes memory leak)
* Improve redisAppendCommandArgv performance 2.5x
* Add support for SO_REUSEADDR
* Fix redisvFormatCommand format parsing
* Add GLib 2.0 adapter
* Refactor reading code into read.c
* Fix errno error buffers to not clobber errors
* Generate pkgconf during build
* Silence _BSD_SOURCE warnings
* Improve digit counting for multibulk creation
### 0.11.0
* Increase the maximum multi-bulk reply depth to 7.
* Increase the read buffer size from 2k to 16k.
* Use poll(2) instead of select(2) to support large fds (>= 1024).
### 0.10.1
* Makefile overhaul. Important to check out if you override one or more
variables using environment variables or via arguments to the "make" tool.
* Issue #45: Fix potential memory leak for a multi bulk reply with 0 elements
being created by the default reply object functions.
* Issue #43: Don't crash in an asynchronous context when Redis returns an error
reply after the connection has been made (this happens when the maximum
number of connections is reached).
### 0.10.0
* See commit log.

[![Build Status](https://travis-ci.org/redis/hiredis.png)](https://travis-ci.org/redis/hiredis)
**This Readme reflects the latest changed in the master branch. See [v1.0.0](https://github.com/redis/hiredis/tree/v1.0.0) for the Readme and documentation for the latest release ([API/ABI history](https://abi-laboratory.pro/?view=timeline&l=hiredis)).**
# HIREDIS
Hiredis is a minimalistic C client library for the [Redis](http://redis.io/) database.
It is minimalistic because it just adds minimal support for the protocol, but
at the same time it uses a high level printf-alike API in order to make it
much higher level than otherwise suggested by its minimal code base and the
lack of explicit bindings for every Redis command.
Apart from supporting sending commands and receiving replies, it comes with
a reply parser that is decoupled from the I/O layer. It
is a stream parser designed for easy reusability, which can for instance be used
in higher level language bindings for efficient reply parsing.
Hiredis only supports the binary-safe Redis protocol, so you can use it with any
Redis version >= 1.2.0.
The library comes with multiple APIs. There is the
*synchronous API*, the *asynchronous API* and the *reply parsing API*.
## Upgrading to `1.0.0`
Version 1.0.0 marks the first stable release of Hiredis.
It includes some minor breaking changes, mostly to make the exposed API more uniform and self-explanatory.
It also bundles the updated `sds` library, to sync up with upstream and Redis.
For code changes see the [Changelog](CHANGELOG.md).
_Note: As described below, a few member names have been changed but most applications should be able to upgrade with minor code changes and recompiling._
## IMPORTANT: Breaking changes from `0.14.1` -> `1.0.0`
* `redisContext` has two additional members (`free_privdata`, and `privctx`).
* `redisOptions.timeout` has been renamed to `redisOptions.connect_timeout`, and we've added `redisOptions.command_timeout`.
* `redisReplyObjectFunctions.createArray` now takes `size_t` instead of `int` for its length parameter.
## IMPORTANT: Breaking changes when upgrading from 0.13.x -> 0.14.x
Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now
protocol errors. This is consistent with the RESP specification. On 32-bit
platforms, the upper bound is lowered to `SIZE_MAX`.
Change `redisReply.len` to `size_t`, as it denotes the the size of a string
User code should compare this to `size_t` values as well. If it was used to
compare to other values, casting might be necessary or can be removed, if
casting was applied before.
## Upgrading from `<0.9.0`
Version 0.9.0 is a major overhaul of hiredis in every aspect. However, upgrading existing
code using hiredis should not be a big pain. The key thing to keep in mind when
upgrading is that hiredis >= 0.9.0 uses a `redisContext*` to keep state, in contrast to
the stateless 0.0.1 that only has a file descriptor to work with.
## Synchronous API
To consume the synchronous API, there are only a few function calls that need to be introduced:
```c
redisContext *redisConnect(const char *ip, int port);
void *redisCommand(redisContext *c, const char *format, ...);
void freeReplyObject(void *reply);
```
### Connecting
The function `redisConnect` is used to create a so-called `redisContext`. The
context is where Hiredis holds state for a connection. The `redisContext`
struct has an integer `err` field that is non-zero when the connection is in
an error state. The field `errstr` will contain a string with a description of
the error. More information on errors can be found in the **Errors** section.
After trying to connect to Redis using `redisConnect` you should
check the `err` field to see if establishing the connection was successful:
```c
redisContext *c = redisConnect("127.0.0.1", 6379);
if (c == NULL || c->err) {
if (c) {
printf("Error: %s\n", c->errstr);
// handle error
} else {
printf("Can't allocate redis context\n");
}
}
```
*Note: A `redisContext` is not thread-safe.*
### Sending commands
There are several ways to issue commands to Redis. The first that will be introduced is
`redisCommand`. This function takes a format similar to printf. In the simplest form,
it is used like this:
```c
reply = redisCommand(context, "SET foo bar");
```
The specifier `%s` interpolates a string in the command, and uses `strlen` to
determine the length of the string:
```c
reply = redisCommand(context, "SET foo %s", value);
```
When you need to pass binary safe strings in a command, the `%b` specifier can be
used. Together with a pointer to the string, it requires a `size_t` length argument
of the string:
```c
reply = redisCommand(context, "SET foo %b", value, (size_t) valuelen);
```
Internally, Hiredis splits the command in different arguments and will
convert it to the protocol used to communicate with Redis.
One or more spaces separates arguments, so you can use the specifiers
anywhere in an argument:
```c
reply = redisCommand(context, "SET key:%s %s", myid, value);
```
### Using replies
The return value of `redisCommand` holds a reply when the command was
successfully executed. When an error occurs, the return value is `NULL` and
the `err` field in the context will be set (see section on **Errors**).
Once an error is returned the context cannot be reused and you should set up
a new connection.
The standard replies that `redisCommand` are of the type `redisReply`. The
`type` field in the `redisReply` should be used to test what kind of reply
was received:
### RESP2
* **`REDIS_REPLY_STATUS`**:
* The command replied with a status reply. The status string can be accessed using `reply->str`.
The length of this string can be accessed using `reply->len`.
* **`REDIS_REPLY_ERROR`**:
* The command replied with an error. The error string can be accessed identical to `REDIS_REPLY_STATUS`.
* **`REDIS_REPLY_INTEGER`**:
* The command replied with an integer. The integer value can be accessed using the
`reply->integer` field of type `long long`.
* **`REDIS_REPLY_NIL`**:
* The command replied with a **nil** object. There is no data to access.
* **`REDIS_REPLY_STRING`**:
* A bulk (string) reply. The value of the reply can be accessed using `reply->str`.
The length of this string can be accessed using `reply->len`.
* **`REDIS_REPLY_ARRAY`**:
* A multi bulk reply. The number of elements in the multi bulk reply is stored in
`reply->elements`. Every element in the multi bulk reply is a `redisReply` object as well
and can be accessed via `reply->element[..index..]`.
Redis may reply with nested arrays but this is fully supported.
### RESP3
Hiredis also supports every new `RESP3` data type which are as follows. For more information about the protocol see the `RESP3` [specification.](https://github.com/antirez/RESP3/blob/master/spec.md)
* **`REDIS_REPLY_DOUBLE`**:
* The command replied with a double-precision floating point number.
The value is stored as a string in the `str` member, and can be converted with `strtod` or similar.
* **`REDIS_REPLY_BOOL`**:
* A boolean true/false reply.
The value is stored in the `integer` member and will be either `0` or `1`.
* **`REDIS_REPLY_MAP`**:
* An array with the added invariant that there will always be an even number of elements.
The MAP is functionally equivelant to `REDIS_REPLY_ARRAY` except for the previously mentioned invariant.
* **`REDIS_REPLY_SET`**:
* An array response where each entry is unique.
Like the MAP type, the data is identical to an array response except there are no duplicate values.
* **`REDIS_REPLY_PUSH`**:
* An array that can be generated spontaneously by Redis.
This array response will always contain at least two subelements. The first contains the type of `PUSH` message (e.g. `message`, or `invalidate`), and the second being a sub-array with the `PUSH` payload itself.
* **`REDIS_REPLY_ATTR`**:
* An array structurally identical to a `MAP` but intended as meta-data about a reply.
_As of Redis 6.0.6 this reply type is not used in Redis_
* **`REDIS_REPLY_BIGNUM`**:
* A string representing an arbitrarily large signed or unsigned integer value.
The number will be encoded as a string in the `str` member of `redisReply`.
* **`REDIS_REPLY_VERB`**:
* A verbatim string, intended to be presented to the user without modification.
The string payload is stored in the `str` memeber, and type data is stored in the `vtype` member (e.g. `txt` for raw text or `md` for markdown).
Replies should be freed using the `freeReplyObject()` function.
Note that this function will take care of freeing sub-reply objects
contained in arrays and nested arrays, so there is no need for the user to
free the sub replies (it is actually harmful and will corrupt the memory).
**Important:** the current version of hiredis (1.0.0) frees replies when the
asynchronous API is used. This means you should not call `freeReplyObject` when
you use this API. The reply is cleaned up by hiredis _after_ the callback
returns. We may introduce a flag to make this configurable in future versions of the library.
### Cleaning up
To disconnect and free the context the following function can be used:
```c
void redisFree(redisContext *c);
```
This function immediately closes the socket and then frees the allocations done in
creating the context.
### Sending commands (cont'd)
Together with `redisCommand`, the function `redisCommandArgv` can be used to issue commands.
It has the following prototype:
```c
void *redisCommandArgv(redisContext *c, int argc, const char **argv, const size_t *argvlen);
```
It takes the number of arguments `argc`, an array of strings `argv` and the lengths of the
arguments `argvlen`. For convenience, `argvlen` may be set to `NULL` and the function will
use `strlen(3)` on every argument to determine its length. Obviously, when any of the arguments
need to be binary safe, the entire array of lengths `argvlen` should be provided.
The return value has the same semantic as `redisCommand`.
### Pipelining
To explain how Hiredis supports pipelining in a blocking connection, there needs to be
understanding of the internal execution flow.
When any of the functions in the `redisCommand` family is called, Hiredis first formats the
command according to the Redis protocol. The formatted command is then put in the output buffer
of the context. This output buffer is dynamic, so it can hold any number of commands.
After the command is put in the output buffer, `redisGetReply` is called. This function has the
following two execution paths:
1. The input buffer is non-empty:
* Try to parse a single reply from the input buffer and return it
* If no reply could be parsed, continue at *2*
2. The input buffer is empty:
* Write the **entire** output buffer to the socket
* Read from the socket until a single reply could be parsed
The function `redisGetReply` is exported as part of the Hiredis API and can be used when a reply
is expected on the socket. To pipeline commands, the only things that needs to be done is
filling up the output buffer. For this cause, two commands can be used that are identical
to the `redisCommand` family, apart from not returning a reply:
```c
void redisAppendCommand(redisContext *c, const char *format, ...);
void redisAppendCommandArgv(redisContext *c, int argc, const char **argv, const size_t *argvlen);
```
After calling either function one or more times, `redisGetReply` can be used to receive the
subsequent replies. The return value for this function is either `REDIS_OK` or `REDIS_ERR`, where
the latter means an error occurred while reading a reply. Just as with the other commands,
the `err` field in the context can be used to find out what the cause of this error is.
The following examples shows a simple pipeline (resulting in only a single call to `write(2)` and
a single call to `read(2)`):
```c
redisReply *reply;
redisAppendCommand(context,"SET foo bar");
redisAppendCommand(context,"GET foo");
redisGetReply(context,(void *)&reply); // reply for SET
freeReplyObject(reply);
redisGetReply(context,(void *)&reply); // reply for GET
freeReplyObject(reply);
```
This API can also be used to implement a blocking subscriber:
```c
reply = redisCommand(context,"SUBSCRIBE foo");
freeReplyObject(reply);
while(redisGetReply(context,(void *)&reply) == REDIS_OK) {
// consume message
freeReplyObject(reply);
}
```
### Errors
When a function call is not successful, depending on the function either `NULL` or `REDIS_ERR` is
returned. The `err` field inside the context will be non-zero and set to one of the
following constants:
* **`REDIS_ERR_IO`**:
There was an I/O error while creating the connection, trying to write
to the socket or read from the socket. If you included `errno.h` in your
application, you can use the global `errno` variable to find out what is
wrong.
* **`REDIS_ERR_EOF`**:
The server closed the connection which resulted in an empty read.
* **`REDIS_ERR_PROTOCOL`**:
There was an error while parsing the protocol.
* **`REDIS_ERR_OTHER`**:
Any other error. Currently, it is only used when a specified hostname to connect
to cannot be resolved.
In every case, the `errstr` field in the context will be set to hold a string representation
of the error.
## Asynchronous API
Hiredis comes with an asynchronous API that works easily with any event library.
Examples are bundled that show using Hiredis with [libev](http://software.schmorp.de/pkg/libev.html)
and [libevent](http://monkey.org/~provos/libevent/).
### Connecting
The function `redisAsyncConnect` can be used to establish a non-blocking connection to
Redis. It returns a pointer to the newly created `redisAsyncContext` struct. The `err` field
should be checked after creation to see if there were errors creating the connection.
Because the connection that will be created is non-blocking, the kernel is not able to
instantly return if the specified host and port is able to accept a connection.
*Note: A `redisAsyncContext` is not thread-safe.*
```c
redisAsyncContext *c = redisAsyncConnect("127.0.0.1", 6379);
if (c->err) {
printf("Error: %s\n", c->errstr);
// handle error
}
```
The asynchronous context can hold a disconnect callback function that is called when the
connection is disconnected (either because of an error or per user request). This function should
have the following prototype:
```c
void(const redisAsyncContext *c, int status);
```
On a disconnect, the `status` argument is set to `REDIS_OK` when disconnection was initiated by the
user, or `REDIS_ERR` when the disconnection was caused by an error. When it is `REDIS_ERR`, the `err`
field in the context can be accessed to find out the cause of the error.
The context object is always freed after the disconnect callback fired. When a reconnect is needed,
the disconnect callback is a good point to do so.
Setting the disconnect callback can only be done once per context. For subsequent calls it will
return `REDIS_ERR`. The function to set the disconnect callback has the following prototype:
```c
int redisAsyncSetDisconnectCallback(redisAsyncContext *ac, redisDisconnectCallback *fn);
```
`ac->data` may be used to pass user data to this callback, the same can be done for redisConnectCallback.
### Sending commands and their callbacks
In an asynchronous context, commands are automatically pipelined due to the nature of an event loop.
Therefore, unlike the synchronous API, there is only a single way to send commands.
Because commands are sent to Redis asynchronously, issuing a command requires a callback function
that is called when the reply is received. Reply callbacks should have the following prototype:
```c
void(redisAsyncContext *c, void *reply, void *privdata);
```
The `privdata` argument can be used to curry arbitrary data to the callback from the point where
the command is initially queued for execution.
The functions that can be used to issue commands in an asynchronous context are:
```c
int redisAsyncCommand(
redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
const char *format, ...);
int redisAsyncCommandArgv(
redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
int argc, const char **argv, const size_t *argvlen);
```
Both functions work like their blocking counterparts. The return value is `REDIS_OK` when the command
was successfully added to the output buffer and `REDIS_ERR` otherwise. Example: when the connection
is being disconnected per user-request, no new commands may be added to the output buffer and `REDIS_ERR` is
returned on calls to the `redisAsyncCommand` family.
If the reply for a command with a `NULL` callback is read, it is immediately freed. When the callback
for a command is non-`NULL`, the memory is freed immediately following the callback: the reply is only
valid for the duration of the callback.
All pending callbacks are called with a `NULL` reply when the context encountered an error.
### Disconnecting
An asynchronous connection can be terminated using:
```c
void redisAsyncDisconnect(redisAsyncContext *ac);
```
When this function is called, the connection is **not** immediately terminated. Instead, new
commands are no longer accepted and the connection is only terminated when all pending commands
have been written to the socket, their respective replies have been read and their respective
callbacks have been executed. After this, the disconnection callback is executed with the
`REDIS_OK` status and the context object is freed.
### Hooking it up to event library *X*
There are a few hooks that need to be set on the context object after it is created.
See the `adapters/` directory for bindings to *libev* and *libevent*.
## Reply parsing API
Hiredis comes with a reply parsing API that makes it easy for writing higher
level language bindings.
The reply parsing API consists of the following functions:
```c
redisReader *redisReaderCreate(void);
void redisReaderFree(redisReader *reader);
int redisReaderFeed(redisReader *reader, const char *buf, size_t len);
int redisReaderGetReply(redisReader *reader, void **reply);
```
The same set of functions are used internally by hiredis when creating a
normal Redis context, the above API just exposes it to the user for a direct
usage.
### Usage
The function `redisReaderCreate` creates a `redisReader` structure that holds a
buffer with unparsed data and state for the protocol parser.
Incoming data -- most likely from a socket -- can be placed in the internal
buffer of the `redisReader` using `redisReaderFeed`. This function will make a
copy of the buffer pointed to by `buf` for `len` bytes. This data is parsed
when `redisReaderGetReply` is called. This function returns an integer status
and a reply object (as described above) via `void **reply`. The returned status
can be either `REDIS_OK` or `REDIS_ERR`, where the latter means something went
wrong (either a protocol error, or an out of memory error).
The parser limits the level of nesting for multi bulk payloads to 7. If the
multi bulk nesting level is higher than this, the parser returns an error.
### Customizing replies
The function `redisReaderGetReply` creates `redisReply` and makes the function
argument `reply` point to the created `redisReply` variable. For instance, if
the response of type `REDIS_REPLY_STATUS` then the `str` field of `redisReply`
will hold the status as a vanilla C string. However, the functions that are
responsible for creating instances of the `redisReply` can be customized by
setting the `fn` field on the `redisReader` struct. This should be done
immediately after creating the `redisReader`.
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
KiB 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:
```c
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.
### Reader max array elements
By default the hiredis reply parser sets the maximum number of multi-bulk elements
to 2^32 - 1 or 4,294,967,295 entries. If you need to process multi-bulk replies
with more than this many elements you can set the value higher or to zero, meaning
unlimited with:
```c
context->reader->maxelements = 0;
```
## SSL/TLS Support
### Building
SSL/TLS support is not built by default and requires an explicit flag:
make USE_SSL=1
This requires OpenSSL development package (e.g. including header files to be
available.
When enabled, SSL/TLS support is built into extra `libhiredis_ssl.a` and
`libhiredis_ssl.so` static/dynamic libraries. This leaves the original libraries
unaffected so no additional dependencies are introduced.
### Using it
First, you'll need to make sure you include the SSL header file:
```c
#include "hiredis.h"
#include "hiredis_ssl.h"
```
You will also need to link against `libhiredis_ssl`, **in addition** to
`libhiredis` and add `-lssl -lcrypto` to satisfy its dependencies.
Hiredis implements SSL/TLS on top of its normal `redisContext` or
`redisAsyncContext`, so you will need to establish a connection first and then
initiate an SSL/TLS handshake.
#### Hiredis OpenSSL Wrappers
Before Hiredis can negotiate an SSL/TLS connection, it is necessary to
initialize OpenSSL and create a context. You can do that in two ways:
1. Work directly with the OpenSSL API to initialize the library's global context
and create `SSL_CTX *` and `SSL *` contexts. With an `SSL *` object you can
call `redisInitiateSSL()`.
2. Work with a set of Hiredis-provided wrappers around OpenSSL, create a
`redisSSLContext` object to hold configuration and use
`redisInitiateSSLWithContext()` to initiate the SSL/TLS handshake.
```c
/* An Hiredis SSL context. It holds SSL configuration and can be reused across
* many contexts.
*/
redisSSLContext *ssl;
/* An error variable to indicate what went wrong, if the context fails to
* initialize.
*/
redisSSLContextError ssl_error;
/* Initialize global OpenSSL state.
*
* You should call this only once when your app initializes, and only if
* you don't explicitly or implicitly initialize OpenSSL it elsewhere.
*/
redisInitOpenSSL();
/* Create SSL context */
ssl = redisCreateSSLContext(
"cacertbundle.crt", /* File name of trusted CA/ca bundle file, optional */
"/path/to/certs", /* Path of trusted certificates, optional */
"client_cert.pem", /* File name of client certificate file, optional */
"client_key.pem", /* File name of client private key, optional */
"redis.mydomain.com", /* Server name to request (SNI), optional */
&ssl_error
) != REDIS_OK) {
printf("SSL error: %s\n", redisSSLContextGetError(ssl_error);
/* Abort... */
}
/* Create Redis context and establish connection */
c = redisConnect("localhost", 6443);
if (c == NULL || c->err) {
/* Handle error and abort... */
}
/* Negotiate SSL/TLS */
if (redisInitiateSSLWithContext(c, ssl) != REDIS_OK) {
/* Handle error, in c->err / c->errstr */
}
```
## RESP3 PUSH replies
Redis 6.0 introduced PUSH replies with the reply-type `>`. These messages are generated spontaneously and can arrive at any time, so must be handled using callbacks.
### Default behavior
Hiredis installs handlers on `redisContext` and `redisAsyncContext` by default, which will intercept and free any PUSH replies detected. This means existing code will work as-is after upgrading to Redis 6 and switching to `RESP3`.
### Custom PUSH handler prototypes
The callback prototypes differ between `redisContext` and `redisAsyncContext`.
#### redisContext
```c
void my_push_handler(void *privdata, void *reply) {
/* Handle the reply */
/* Note: We need to free the reply in our custom handler for
blocking contexts. This lets us keep the reply if
we want. */
freeReplyObject(reply);
}
```
#### redisAsyncContext
```c
void my_async_push_handler(redisAsyncContext *ac, void *reply) {
/* Handle the reply */
/* Note: Because async hiredis always frees replies, you should
not call freeReplyObject in an async push callback. */
}
```
### Installing a custom handler
There are two ways to set your own PUSH handlers.
1. Set `push_cb` or `async_push_cb` in the `redisOptions` struct and connect with `redisConnectWithOptions` or `redisAsyncConnectWithOptions`.
```c
redisOptions = {0};
REDIS_OPTIONS_SET_TCP(&options, "127.0.0.1", 6379);
options->push_cb = my_push_handler;
redisContext *context = redisConnectWithOptions(&options);
```
2. Call `redisSetPushCallback` or `redisAsyncSetPushCallback` on a connected context.
```c
redisContext *context = redisConnect("127.0.0.1", 6379);
redisSetPushCallback(context, my_push_handler);
```
_Note `redisSetPushCallback` and `redisAsyncSetPushCallback` both return any currently configured handler, making it easy to override and then return to the old value._
### Specifying no handler
If you have a unique use-case where you don't want hiredis to automatically intercept and free PUSH replies, you will want to configure no handler at all. This can be done in two ways.
1. Set the `REDIS_OPT_NO_PUSH_AUTOFREE` flag in `redisOptions` and leave the callback function pointer `NULL`.
```c
redisOptions = {0};
REDIS_OPTIONS_SET_TCP(&options, "127.0.0.1", 6379);
options->options |= REDIS_OPT_NO_PUSH_AUTOFREE;
redisContext *context = redisConnectWithOptions(&options);
```
3. Call `redisSetPushCallback` with `NULL` once connected.
```c
redisContext *context = redisConnect("127.0.0.1", 6379);
redisSetPushCallback(context, NULL);
```
_Note: With no handler configured, calls to `redisCommand` may generate more than one reply, so this strategy is only applicable when there's some kind of blocking`redisGetReply()` loop (e.g. `MONITOR` or `SUBSCRIBE` workloads)._
## Allocator injection
Hiredis uses a pass-thru structure of function pointers defined in [alloc.h](https://github.com/redis/hiredis/blob/f5d25850/alloc.h#L41) that contain the currently configured allocation and deallocation functions. By default they just point to libc (`malloc`, `calloc`, `realloc`, etc).
### Overriding
One can override the allocators like so:
```c
hiredisAllocFuncs myfuncs = {
.mallocFn = my_malloc,
.callocFn = my_calloc,
.reallocFn = my_realloc,
.strdupFn = my_strdup,
.freeFn = my_free,
};
// Override allocators (function returns current allocators if needed)
hiredisAllocFuncs orig = hiredisSetAllocators(&myfuncs);
```
To reset the allocators to their default libc function simply call:
```c
hiredisResetAllocators();
```
