+Where to find complete Redis documentation?
+-------------------------------------------
+
+This README is just a fast "quick start" document. You can find more detailed
+documentation at http://redis.io
+
+Building Redis
+--------------
+
+Redis can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD.
+We support big endian and little endian architectures.
+
+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 there.
+
+It is as simple as:
+
+    % make
+
+You can run a 32 bit Redis binary using:
+
+    % make 32bit
+
+After building Redis is a good idea to test it, using:
+
+    % make test
+
+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 packages 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
+
+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 passing parameters directly

+
+    % ./redis-server --port 9999 --slaveof 127.0.0.1 6379

+
+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 want just to play a bit with Redis, but if you are installing
+it the proper way for a production system, we have a script doing this
+for Ubuntu and Debian systems:
+
+    % cd utils
+    % ./install_server.sh
+
+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.

-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 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 is also non-volatile.
-* Implementation of data structures stress on memory efficiency, so data structures inside Redis will likely use less memory compared to the same data structure modeled using an high level programming language.
-* Redis offers a number of features that are natural to find in a database, like replication, tunable levels of durability, cluster, 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 to 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 Redis official 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 there.
-
-It is as simple as:
-
-    % make
-
-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
-
-Fixing build problems with dependencies or cached build options
----------
-
-Redis has some dependencies which are included into 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.

-the following steps:

-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 `anitrez/redis`. An exception to this rule is `deps/geohash-int` which is the low level geocoding library used by Redis: it originated from a different project, but at this point it diverged so much that it is developed as a separated entity directly inside the Redis repository.
-
-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 to `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 slave.
-
-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 writable.
-
-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()` setups 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 timedout 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 eviciton of keys with a time to live set via the `EXPIRE` command.
-* `freeMemoryIfNeeded()` 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 slaves
-(which in Redis are just special clients):
-
-* `createClient()` allocates and initializes a new client.
-* the `addReply*()` family of functions are used by commands 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 from 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 to call
-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 commands
-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 slave role
-of Redis.
-
-One of the most important functions inside this file is `replicationFeedSlaves()` that writes commands to the clients representing slave instances connected
-to our master, so that the slaves 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
-slaves, or to continue the replication after a disconnection.
-
-Other C files
----
-
-* `t_hash.c`, `t_list.c`, `t_set.c`, `t_string.c` and `t_zset.c` contains the implementation of the Redis data types. They implement both an API to access a given data type, and the client commands 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 from the rest of the Redis implementation and is simple enough to understand if you are familar 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].
-

-
-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 commands implementations inside th Redis source code
-that can serve as examples of actual commands implementations. To write
-a few toy commands can be a good exercise to familiarize with the code base.
-

-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.
-* **geohash-int** is inside the dependencies directory but is actually part of the Redis project, since it is our private fork (heavily modified) of a library initially developed for Ardb, which is in turn a fork of Redis.
-* **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 unmodified. We only change 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.
-
-So in order to upgrade jemalloc:
-
-1. Remove the jemalloc directory.
-2. Substitute it with the new jemalloc source tree.
-
-Geohash
----
-
-This is never upgraded since it's part of the Redis project. If there are changes to merge from Ardb there is the need to manually check differences, but at this point the source code is pretty different.
-
-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 adviced 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 thet 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 expecteed, 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 toa void direct bytecode exectuion.

-### 1.0.0 (unreleased)
-
-**Fixes**:
-
-* 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
-
-**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.
-
-* Remove backwards compatibility macro's
-
-This removes the following old function aliases, use the new name now:
-
-| Old                         | New                    |

-| 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 possiblity 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
-

+    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);
-```
+
+    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);
-```
+
+    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);
-```
+
+    reply = redisCommand(context, "SET key:%s %s", myid, value);

+The context object is always free'd 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);
-```
+
+    int redisAsyncSetDisconnectCallback(redisAsyncContext *ac, redisDisconnectCallback *fn);
+
 ### 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);
-```
+
+    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);
-```
+
+    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.

-* 4.0.3 (September 24, 2015)
-
-  This bugfix release continues the trend of xallocx() and heap profiling fixes.
-
-  Bug fixes:
-  - Fix xallocx(..., MALLOCX_ZERO) to zero all trailing bytes of large
-    allocations when --enable-cache-oblivious configure option is enabled.
-  - Fix xallocx(..., MALLOCX_ZERO) to zero trailing bytes of huge allocations
-    when resizing from/to a size class that is not a multiple of the chunk size.
-  - Fix prof_tctx_dump_iter() to filter out nodes that were created after heap
-    profile dumping started.
-  - Work around a potentially bad thread-specific data initialization
-    interaction with NPTL (glibc's pthreads implementation).
-
-* 4.0.2 (September 21, 2015)
-
-  This bugfix release addresses a few bugs specific to heap profiling.
-
-  Bug fixes:
-  - Fix ixallocx_prof_sample() to never modify nor create sampled small
-    allocations.  xallocx() is in general incapable of moving small allocations,
-    so this fix removes buggy code without loss of generality.
-  - Fix irallocx_prof_sample() to always allocate large regions, even when
-    alignment is non-zero.
-  - Fix prof_alloc_rollback() to read tdata from thread-specific data rather
-    than dereferencing a potentially invalid tctx.
-
-* 4.0.1 (September 15, 2015)
-
-  This is a bugfix release that is somewhat high risk due to the amount of
-  refactoring required to address deep xallocx() problems.  As a side effect of
-  these fixes, xallocx() now tries harder to partially fulfill requests for
-  optional extra space.  Note that a couple of minor heap profiling
-  optimizations are included, but these are better thought of as performance
-  fixes that were integral to disovering most of the other bugs.
-
-  Optimizations:
-  - Avoid a chunk metadata read in arena_prof_tctx_set(), since it is in the
-    fast path when heap profiling is enabled.  Additionally, split a special
-    case out into arena_prof_tctx_reset(), which also avoids chunk metadata
-    reads.
-  - Optimize irallocx_prof() to optimistically update the sampler state.  The
-    prior implementation appears to have been a holdover from when
-    rallocx()/xallocx() functionality was combined as rallocm().
-
-  Bug fixes:
-  - Fix TLS configuration such that it is enabled by default for platforms on
-    which it works correctly.
-  - Fix arenas_cache_cleanup() and arena_get_hard() to handle
-    allocation/deallocation within the application's thread-specific data
-    cleanup functions even after arenas_cache is torn down.
-  - Fix xallocx() bugs related to size+extra exceeding HUGE_MAXCLASS.
-  - Fix chunk purge hook calls for in-place huge shrinking reallocation to
-    specify the old chunk size rather than the new chunk size.  This bug caused
-    no correctness issues for the default chunk purge function, but was
-    visible to custom functions set via the "arena.<i>.chunk_hooks" mallctl.
-  - Fix heap profiling bugs:
-    + Fix heap profiling to distinguish among otherwise identical sample sites
-      with interposed resets (triggered via the "prof.reset" mallctl).  This bug
-      could cause data structure corruption that would most likely result in a
-      segfault.
-    + Fix irealloc_prof() to prof_alloc_rollback() on OOM.
-    + Make one call to prof_active_get_unlocked() per allocation event, and use
-      the result throughout the relevant functions that handle an allocation
-      event.  Also add a missing check in prof_realloc().  These fixes protect
-      allocation events against concurrent prof_active changes.
-    + Fix ixallocx_prof() to pass usize_max and zero to ixallocx_prof_sample()
-      in the correct order.
-    + Fix prof_realloc() to call prof_free_sampled_object() after calling
-      prof_malloc_sample_object().  Prior to this fix, if tctx and old_tctx were
-      the same, the tctx could have been prematurely destroyed.
-  - Fix portability bugs:
-    + Don't bitshift by negative amounts when encoding/decoding run sizes in
-      chunk header maps.  This affected systems with page sizes greater than 8
-      KiB.
-    + Rename index_t to szind_t to avoid an existing type on Solaris.
-    + Add JEMALLOC_CXX_THROW to the memalign() function prototype, in order to
-      match glibc and avoid compilation errors when including both
-      jemalloc/jemalloc.h and malloc.h in C++ code.
-    + Don't assume that /bin/sh is appropriate when running size_classes.sh
-      during configuration.
-    + Consider __sparcv9 a synonym for __sparc64__ when defining LG_QUANTUM.
-    + Link tests to librt if it contains clock_gettime(2).
-
-* 4.0.0 (August 17, 2015)
-
-  This version contains many speed and space optimizations, both minor and
-  major.  The major themes are generalization, unification, and simplification.
-  Although many of these optimizations cause no visible behavior change, their
-  cumulative effect is substantial.
-
-  New features:
-  - Normalize size class spacing to be consistent across the complete size
-    range.  By default there are four size classes per size doubling, but this
-    is now configurable via the --with-lg-size-class-group option.  Also add the
-    --with-lg-page, --with-lg-page-sizes, --with-lg-quantum, and
-    --with-lg-tiny-min options, which can be used to tweak page and size class
-    settings.  Impacts:
-    + Worst case performance for incrementally growing/shrinking reallocation
-      is improved because there are far fewer size classes, and therefore
-      copying happens less often.
-    + Internal fragmentation is limited to 20% for all but the smallest size
-      classes (those less than four times the quantum).  (1B + 4 KiB)
-      and (1B + 4 MiB) previously suffered nearly 50% internal fragmentation.
-    + Chunk fragmentation tends to be lower because there are fewer distinct run
-      sizes to pack.
-  - Add support for explicit tcaches.  The "tcache.create", "tcache.flush", and
-    "tcache.destroy" mallctls control tcache lifetime and flushing, and the
-    MALLOCX_TCACHE(tc) and MALLOCX_TCACHE_NONE flags to the *allocx() API
-    control which tcache is used for each operation.
-  - Implement per thread heap profiling, as well as the ability to
-    enable/disable heap profiling on a per thread basis.  Add the "prof.reset",
-    "prof.lg_sample", "thread.prof.name", "thread.prof.active",
-    "opt.prof_thread_active_init", "prof.thread_active_init", and
-    "thread.prof.active" mallctls.
-  - Add support for per arena application-specified chunk allocators, configured
-    via the "arena.<i>.chunk_hooks" mallctl.
-  - Refactor huge allocation to be managed by arenas, so that arenas now
-    function as general purpose independent allocators.  This is important in
-    the context of user-specified chunk allocators, aside from the scalability
-    benefits.  Related new statistics:
-    + The "stats.arenas.<i>.huge.allocated", "stats.arenas.<i>.huge.nmalloc",
-      "stats.arenas.<i>.huge.ndalloc", and "stats.arenas.<i>.huge.nrequests"
-      mallctls provide high level per arena huge allocation statistics.
-    + The "arenas.nhchunks", "arenas.hchunk.<i>.size",
-      "stats.arenas.<i>.hchunks.<j>.nmalloc",
-      "stats.arenas.<i>.hchunks.<j>.ndalloc",
-      "stats.arenas.<i>.hchunks.<j>.nrequests", and
-      "stats.arenas.<i>.hchunks.<j>.curhchunks" mallctls provide per size class
-      statistics.
-  - Add the 'util' column to malloc_stats_print() output, which reports the
-    proportion of available regions that are currently in use for each small
-    size class.
-  - Add "alloc" and "free" modes for for junk filling (see the "opt.junk"
-    mallctl), so that it is possible to separately enable junk filling for
-    allocation versus deallocation.
-  - Add the jemalloc-config script, which provides information about how
-    jemalloc was configured, and how to integrate it into application builds.
-  - Add metadata statistics, which are accessible via the "stats.metadata",
-    "stats.arenas.<i>.metadata.mapped", and
-    "stats.arenas.<i>.metadata.allocated" mallctls.
-  - Add the "stats.resident" mallctl, which reports the upper limit of
-    physically resident memory mapped by the allocator.
-  - Add per arena control over unused dirty page purging, via the
-    "arenas.lg_dirty_mult", "arena.<i>.lg_dirty_mult", and
-    "stats.arenas.<i>.lg_dirty_mult" mallctls.
-  - Add the "prof.gdump" mallctl, which makes it possible to toggle the gdump
-    feature on/off during program execution.
-  - Add sdallocx(), which implements sized deallocation.  The primary
-    optimization over dallocx() is the removal of a metadata read, which often
-    suffers an L1 cache miss.
-  - Add missing header includes in jemalloc/jemalloc.h, so that applications
-    only have to #include <jemalloc/jemalloc.h>.
-  - Add support for additional platforms:
-    + Bitrig
-    + Cygwin
-    + DragonFlyBSD
-    + iOS
-    + OpenBSD
-    + OpenRISC/or1k
-
-  Optimizations:
-  - Maintain dirty runs in per arena LRUs rather than in per arena trees of
-    dirty-run-containing chunks.  In practice this change significantly reduces
-    dirty page purging volume.
-  - Integrate whole chunks into the unused dirty page purging machinery.  This
-    reduces the cost of repeated huge allocation/deallocation, because it
-    effectively introduces a cache of chunks.
-  - Split the arena chunk map into two separate arrays, in order to increase
-    cache locality for the frequently accessed bits.
-  - Move small run metadata out of runs, into arena chunk headers.  This reduces
-    run fragmentation, smaller runs reduce external fragmentation for small size
-    classes, and packed (less uniformly aligned) metadata layout improves CPU
-    cache set distribution.
-  - Randomly distribute large allocation base pointer alignment relative to page
-    boundaries in order to more uniformly utilize CPU cache sets.  This can be
-    disabled via the --disable-cache-oblivious configure option, and queried via
-    the "config.cache_oblivious" mallctl.
-  - Micro-optimize the fast paths for the public API functions.
-  - Refactor thread-specific data to reside in a single structure.  This assures
-    that only a single TLS read is necessary per call into the public API.
-  - Implement in-place huge allocation growing and shrinking.
-  - Refactor rtree (radix tree for chunk lookups) to be lock-free, and make
-    additional optimizations that reduce maximum lookup depth to one or two
-    levels.  This resolves what was a concurrency bottleneck for per arena huge
-    allocation, because a global data structure is critical for determining
-    which arenas own which huge allocations.
-
-  Incompatible changes:
-  - Replace --enable-cc-silence with --disable-cc-silence to suppress spurious
-    warnings by default.
-  - Assure that the constness of malloc_usable_size()'s return type matches that
-    of the system implementation.
-  - Change the heap profile dump format to support per thread heap profiling,
-    rename pprof to jeprof, and enhance it with the --thread=<n> option.  As a
-    result, the bundled jeprof must now be used rather than the upstream
-    (gperftools) pprof.
-  - Disable "opt.prof_final" by default, in order to avoid atexit(3), which can
-    internally deadlock on some platforms.
-  - Change the "arenas.nlruns" mallctl type from size_t to unsigned.
-  - Replace the "stats.arenas.<i>.bins.<j>.allocated" mallctl with
-    "stats.arenas.<i>.bins.<j>.curregs".
-  - Ignore MALLOC_CONF in set{uid,gid,cap} binaries.
-  - Ignore MALLOCX_ARENA(a) in dallocx(), in favor of using the
-    MALLOCX_TCACHE(tc) and MALLOCX_TCACHE_NONE flags to control tcache usage.
-
-  Removed features:
-  - Remove the *allocm() API, which is superseded by the *allocx() API.
-  - Remove the --enable-dss options, and make dss non-optional on all platforms
-    which support sbrk(2).
-  - Remove the "arenas.purge" mallctl, which was obsoleted by the
-    "arena.<i>.purge" mallctl in 3.1.0.
-  - Remove the unnecessary "opt.valgrind" mallctl; jemalloc automatically
-    detects whether it is running inside Valgrind.
-  - Remove the "stats.huge.allocated", "stats.huge.nmalloc", and
-    "stats.huge.ndalloc" mallctls.
-  - Remove the --enable-mremap option.
-  - Remove the "stats.chunks.current", "stats.chunks.total", and
-    "stats.chunks.high" mallctls.
-
-  Bug fixes:
-  - Fix the cactive statistic to decrease (rather than increase) when active
-    memory decreases.  This regression was first released in 3.5.0.
-  - Fix OOM handling in memalign() and valloc().  A variant of this bug existed
-    in all releases since 2.0.0, which introduced these functions.
-  - Fix an OOM-related regression in arena_tcache_fill_small(), which could
-    cause cache corruption on OOM.  This regression was present in all releases
-    from 2.2.0 through 3.6.0.
-  - Fix size class overflow handling for malloc(), posix_memalign(), memalign(),
-    calloc(), and realloc() when profiling is enabled.
-  - Fix the "arena.<i>.dss" mallctl to return an error if "primary" or
-    "secondary" precedence is specified, but sbrk(2) is not supported.
-  - Fix fallback lg_floor() implementations to handle extremely large inputs.
-  - Ensure the default purgeable zone is after the default zone on OS X.
-  - Fix latent bugs in atomic_*().
-  - Fix the "arena.<i>.dss" mallctl to handle read-only calls.
-  - Fix tls_model configuration to enable the initial-exec model when possible.
-  - Mark malloc_conf as a weak symbol so that the application can override it.
-  - Correctly detect glibc's adaptive pthread mutexes.
-  - Fix the --without-export configure option.

---with-lg-page=<lg-page>
-    Specify the base 2 log of the system page size.  This option is only useful
-    when cross compiling, since the configure script automatically determines
-    the host's page size by default.
-
---with-lg-page-sizes=<lg-page-sizes>
-    Specify the comma-separated base 2 logs of the page sizes to support.  This
-    option may be useful when cross-compiling in combination with
-    --with-lg-page, but its primary use case is for integration with FreeBSD's
-    libc, wherein jemalloc is embedded.
-
---with-lg-size-class-group=<lg-size-class-group>
-    Specify the base 2 log of how many size classes to use for each doubling in
-    size.  By default jemalloc uses <lg-size-class-group>=2, which results in
-    e.g. the following size classes:
-
-      [...], 64,
-      80, 96, 112, 128,
-      160, [...]
-
-    <lg-size-class-group>=3 results in e.g. the following size classes:
-
-      [...], 64,
-      72, 80, 88, 96, 104, 112, 120, 128,
-      144, [...]
-
-    The minimal <lg-size-class-group>=0 causes jemalloc to only provide size
-    classes that are powers of 2:
-
-      [...],
-      64,
-      128,
-      256,
-      [...]
-
-    An implementation detail currently limits the total number of small size
-    classes to 255, and a compilation error will result if the
-    <lg-size-class-group> you specify cannot be supported.  The limit is
-    roughly <lg-size-class-group>=4, depending on page size.
-
---with-lg-quantum=<lg-quantum>
-    Specify the base 2 log of the minimum allocation alignment.  jemalloc needs
-    to know the minimum alignment that meets the following C standard
-    requirement (quoted from the April 12, 2011 draft of the C11 standard):
-
-      The pointer returned if the allocation succeeds is suitably aligned so
-      that it may be assigned to a pointer to any type of object with a
-      fundamental alignment requirement and then used to access such an object
-      or an array of such objects in the space allocated [...]
-
-    This setting is architecture-specific, and although jemalloc includes known
-    safe values for the most commonly used modern architectures, there is a
-    wrinkle related to GNU libc (glibc) that may impact your choice of
-    <lg-quantum>.  On most modern architectures, this mandates 16-byte alignment
-    (<lg-quantum>=4), but the glibc developers chose not to meet this
-    requirement for performance reasons.  An old discussion can be found at
-    https://sourceware.org/bugzilla/show_bug.cgi?id=206 .  Unlike glibc,
-    jemalloc does follow the C standard by default (caveat: jemalloc
-    technically cheats if --with-lg-tiny-min is smaller than
-    --with-lg-quantum), but the fact that Linux systems already work around
-    this allocator noncompliance means that it is generally safe in practice to
-    let jemalloc's minimum alignment follow glibc's lead.  If you specify
-    --with-lg-quantum=3 during configuration, jemalloc will provide additional
-    size classes that are not 16-byte-aligned (24, 40, and 56, assuming
-    --with-lg-size-class-group=2).
-
---with-lg-tiny-min=<lg-tiny-min>
-    Specify the base 2 log of the minimum tiny size class to support.  Tiny
-    size classes are powers of 2 less than the quantum, and are only
-    incorporated if <lg-tiny-min> is less than <lg-quantum> (see
-    --with-lg-quantum).  Tiny size classes technically violate the C standard
-    requirement for minimum alignment, and crashes could conceivably result if
-    the compiler were to generate instructions that made alignment assumptions,
-    both because illegal instruction traps could result, and because accesses
-    could straddle page boundaries and cause segmentation faults due to
-    accessing unmapped addresses.
-
-    The default of <lg-tiny-min>=3 works well in practice even on architectures
-    that technically require 16-byte alignment, probably for the same reason
-    --with-lg-quantum=3 works.  Smaller tiny size classes can, and will, cause
-    crashes (see https://bugzilla.mozilla.org/show_bug.cgi?id=691003 for an
-    example).
-
-    This option is rarely useful, and is mainly provided as documentation of a
-    subtle implementation detail.  If you do use this option, specify a
-    value in [3, ..., <lg-quantum>].
