-Hello! This file is just a placeholder, since this is the "unstable" branch
-of Redis, the place where all the development happens.
+Redis 2.8 release notes
+=======================
 
-There is no release notes for this branch, it gets forked into another branch
-every time there is a partial feature freeze in order to eventually create
-a new stable release.
+** IMPORTANT ** Check the 'Migrating from 2.6 to 2.8' section at the end of
+                this file for information about what changed between 2.6 and
+                2.8 and how this may affect your application.
 
-Usually "unstable" is stable enough for you to use it in development environments
-however you should never use it in production environments. It is possible
-to download the latest stable release here:
+--------------------------------------------------------------------------------
+Upgrade urgency levels:
 
-    http://download.redis.io/releases/redis-stable.tar.gz
+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.

+
+The following is a list of improvements in Redis 2.8, compared to Redis 2.6.
+
+* [NEW] Slaves are now able to partially resynchronize with the master, so most
+        of the times a full resynchronization with the RDB creation in the master

+        amount of time.
+* [NEW] Experimental IPv6 support.
+* [NEW] Slaves explicitly ping masters now, a master is able to detect a timed out
+        slave independently.
+* [NEW] Masters can stop accepting writes if not enough slaves with a given

+* [NEW] Better Lua scripts error reporting.
+* [NEW] SDIFF performance improved.
+* [FIX] A number of bugfixes.
+
+Migrating from 2.6 to 2.8
+=========================
+
+Redis 2.6 is mostly a strict subset of 2.8. However there are a few things
+that you should be aware of:
+
+The following commands changed behavior:
+
+    * SORT with ALPHA now sorts according to local collation locale if no STORE
+      option is used.
+    * ZADD/ZINCRBY are now able to accept a bigger range of values as valid
+      scores, that is, all the values you may end having as a result of
+      calling ZINCRBY multiple times.
+    * Many errors are now prefixed by a more specific error code instead of
+      the generic -ERR, for example -WRONGTYPE, -NOAUTH, ...
+    * PUBLISH called inside Lua scripts is now correctly propagated to slaves.
+
+The following redis.conf and CONFIG GET / SET parameters changed:
+
+    * logfile now uses the empty string in order to log to standard output,
+      so 'logfile stdout' is now invalid, use 'logfile ""' instead.
+
+The following INFO fields changed format in a non-backward compatible way:
+
+    * The list of slaves in INFO is now in field=value format.
+
+Replication:
+
+    Redis 2.8 can be used as slave for Redis 2.6, but doing this is only
+    a good idea for the short amount of time needed to upgrade your servers.
+    We suggest to update both master and slaves at about the same time.

+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
+as options using the command line. Examples:
+
+    % ./redis-server --port 9999 --slaveof 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.
+
+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 here:
+
+    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 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
+
+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 the 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.
-
-There are also many other files not described here, but it is useless to
-cover everything. We want to just help you with the first steps.
-Eventually you'll find your way inside the Redis code base :-)
-
-Enjoy!

-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 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 tose steps:
-
-1. Remove the jemalloc directory.
-2. Substitute it with the new jemalloc source tree.
-3. Edit the Makefile localted 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 three, 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.
-
-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 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 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 execution.

@@ -1,136 +1,3 @@
-### 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                    |

-
-* 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
-

+struct has an integer `err` field that is non-zero when an 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) {

         // 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");
-```
+
+    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, 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.

+Building and installing jemalloc can be as simple as typing the following while
+in the root directory of the source tree:
+
+    ./configure
+    make
+    make install
+
+=== Advanced configuration =====================================================
+
+The 'configure' script supports numerous options that allow control of which
+functionality is enabled, where jemalloc is installed, etc.  Optionally, pass
+any of the following arguments (not a definitive list) to 'configure':
+
+--help
+    Print a definitive list of options.
+
+--prefix=<install-root-dir>
+    Set the base directory in which to install.  For example:
+
+        ./configure --prefix=/usr/local
+
+    will cause files to be installed into /usr/local/include, /usr/local/lib,
+    and /usr/local/man.
+
+--with-rpath=<colon-separated-rpath>
+    Embed one or more library paths, so that libjemalloc can find the libraries
+    it is linked to.  This works only on ELF-based systems.
+
+--with-mangling=<map>
+    Mangle public symbols specified in <map> which is a comma-separated list of
+    name:mangled pairs.
+
+    For example, to use ld's --wrap option as an alternative method for
+    overriding libc's malloc implementation, specify something like:
+
+      --with-mangling=malloc:__wrap_malloc,free:__wrap_free[...]
+
+    Note that mangling happens prior to application of the prefix specified by
+    --with-jemalloc-prefix, and mangled symbols are then ignored when applying
+    the prefix.
+
+--with-jemalloc-prefix=<prefix>
+    Prefix all public APIs with <prefix>.  For example, if <prefix> is
+    "prefix_", API changes like the following occur:
+
+      malloc()         --> prefix_malloc()
+      malloc_conf      --> prefix_malloc_conf
+      /etc/malloc.conf --> /etc/prefix_malloc.conf
+      MALLOC_CONF      --> PREFIX_MALLOC_CONF
+
+    This makes it possible to use jemalloc at the same time as the system
+    allocator, or even to use multiple copies of jemalloc simultaneously.
+
+    By default, the prefix is "", except on OS X, where it is "je_".  On OS X,
+    jemalloc overlays the default malloc zone, but makes no attempt to actually
+    replace the "malloc", "calloc", etc. symbols.
+
+--with-private-namespace=<prefix>
+    Prefix all library-private APIs with <prefix>.  For shared libraries,
+    symbol visibility mechanisms prevent these symbols from being exported, but
+    for static libraries, naming collisions are a real possibility.  By
+    default, the prefix is "" (empty string).
+
+--with-install-suffix=<suffix>
+    Append <suffix> to the base name of all installed files, such that multiple
+    versions of jemalloc can coexist in the same installation directory.  For
+    example, libjemalloc.so.0 becomes libjemalloc<suffix>.so.0.
+
+--enable-cc-silence
+    Enable code that silences non-useful compiler warnings.  This is helpful
+    when trying to tell serious warnings from those due to compiler
+    limitations, but it potentially incurs a performance penalty.
+
+--enable-debug
+    Enable assertions and validation code.  This incurs a substantial
+    performance hit, but is very useful during application development.
+
+--disable-stats
+    Disable statistics gathering functionality.  See the "opt.stats_print"
+    option documentation for usage details.
+
+--enable-prof
+    Enable heap profiling and leak detection functionality.  See the "opt.prof"
+    option documentation for usage details.  When enabled, there are several
+    approaches to backtracing, and the configure script chooses the first one
+    in the following list that appears to function correctly:
+
+    + libunwind      (requires --enable-prof-libunwind)
+    + libgcc         (unless --disable-prof-libgcc)
+    + gcc intrinsics (unless --disable-prof-gcc)
+
+--enable-prof-libunwind
+    Use the libunwind library (http://www.nongnu.org/libunwind/) for stack
+    backtracing.
+
+--disable-prof-libgcc
+    Disable the use of libgcc's backtracing functionality.
+
+--disable-prof-gcc
+    Disable the use of gcc intrinsics for backtracing.
+
+--with-static-libunwind=<libunwind.a>
+    Statically link against the specified libunwind.a rather than dynamically
+    linking with -lunwind.
+
+--disable-tcache
+    Disable thread-specific caches for small objects.  Objects are cached and
+    released in bulk, thus reducing the total number of mutex operations.  See
+    the "opt.tcache" option for usage details.
+
+--enable-mremap
+    Enable huge realloc() via mremap(2).  mremap() is disabled by default
+    because the flavor used is specific to Linux, which has a quirk in its
+    virtual memory allocation algorithm that causes semi-permanent VM map holes
+    under normal jemalloc operation.
+
+--disable-munmap
+    Disable virtual memory deallocation via munmap(2); instead keep track of
+    the virtual memory for later use.  munmap() is disabled by default (i.e.
+    --disable-munmap is implied) on Linux, which has a quirk in its virtual
+    memory allocation algorithm that causes semi-permanent VM map holes under
+    normal jemalloc operation.
+
+--enable-dss
+    Enable support for page allocation/deallocation via sbrk(2), in addition to
+    mmap(2).
+
+--disable-fill
+    Disable support for junk/zero filling of memory, quarantine, and redzones.
+    See the "opt.junk", "opt.zero", "opt.quarantine", and "opt.redzone" option
+    documentation for usage details.
+
+--disable-valgrind
+    Disable support for Valgrind.
+
+--disable-experimental
+    Disable support for the experimental API (*allocm()).
+
+--enable-utrace
+    Enable utrace(2)-based allocation tracing.  This feature is not broadly
+    portable (FreeBSD has it, but Linux and OS X do not).
+
+--enable-xmalloc
+    Enable support for optional immediate termination due to out-of-memory
+    errors, as is commonly implemented by "xmalloc" wrapper function for malloc.
+    See the "opt.xmalloc" option documentation for usage details.
+
+--enable-lazy-lock
+    Enable code that wraps pthread_create() to detect when an application
+    switches from single-threaded to multi-threaded mode, so that it can avoid
+    mutex locking/unlocking operations while in single-threaded mode.  In
+    practice, this feature usually has little impact on performance unless
+    thread-specific caching is disabled.
+
+--disable-tls
+    Disable thread-local storage (TLS), which allows for fast access to
+    thread-local variables via the __thread keyword.  If TLS is available,
+    jemalloc uses it for several purposes.
+
+--with-xslroot=<path>
+    Specify where to find DocBook XSL stylesheets when building the
+    documentation.
+
+The following environment variables (not a definitive list) impact configure's
+behavior:
+
+CFLAGS="?"
+    Pass these flags to the compiler.  You probably shouldn't define this unless
+    you know what you are doing.  (Use EXTRA_CFLAGS instead.)
+
+EXTRA_CFLAGS="?"
+    Append these flags to CFLAGS.  This makes it possible to add flags such as
+    -Werror, while allowing the configure script to determine what other flags
+    are appropriate for the specified configuration.
+
+    The configure script specifically checks whether an optimization flag (-O*)
+    is specified in EXTRA_CFLAGS, and refrains from specifying an optimization
+    level if it finds that one has already been specified.
+
+CPPFLAGS="?"
+    Pass these flags to the C preprocessor.  Note that CFLAGS is not passed to
+    'cpp' when 'configure' is looking for include files, so you must use
+    CPPFLAGS instead if you need to help 'configure' find header files.
+
+LD_LIBRARY_PATH="?"
+    'ld' uses this colon-separated list to find libraries.
+
+LDFLAGS="?"
+    Pass these flags when linking.
+
+PATH="?"
+    'configure' uses this to find programs.
+
+=== Advanced compilation =======================================================
+
+To build only parts of jemalloc, use the following targets:
+
+    build_lib_shared
+    build_lib_static
+    build_lib
+    build_doc_html
+    build_doc_man
+    build_doc
+
+To install only parts of jemalloc, use the following targets:
+
+    install_bin
+    install_include
+    install_lib_shared
+    install_lib_static
+    install_lib
+    install_doc_html
+    install_doc_man
+    install_doc
+
+To clean up build results to varying degrees, use the following make targets:
+
+    clean
+    distclean
+    relclean
+
+=== Advanced installation ======================================================
+
+Optionally, define make variables when invoking make, including (not
+exclusively):
+
+INCLUDEDIR="?"
+    Use this as the installation prefix for header files.
+
+LIBDIR="?"
+    Use this as the installation prefix for libraries.
+
+MANDIR="?"
+    Use this as the installation prefix for man pages.
+
+DESTDIR="?"
+    Prepend DESTDIR to INCLUDEDIR, LIBDIR, DATADIR, and MANDIR.  This is useful
+    when installing to a different path than was specified via --prefix.
+
+CC="?"
+    Use this to invoke the C compiler.
+
+CFLAGS="?"
+    Pass these flags to the compiler.
+
+CPPFLAGS="?"
+    Pass these flags to the C preprocessor.
+
+LDFLAGS="?"
+    Pass these flags when linking.
+
+PATH="?"
+    Use this to search for programs used during configuration and building.
+
+=== Development ================================================================
+
+If you intend to make non-trivial changes to jemalloc, use the 'autogen.sh'
+script rather than 'configure'.  This re-generates 'configure', enables
+configuration dependency rules, and enables re-generation of automatically
+generated source files.
+
+The build system supports using an object directory separate from the source
+tree.  For example, you can create an 'obj' directory, and from within that
+directory, issue configuration and build commands:
+
+    autoconf
+    mkdir obj
+    cd obj
+    ../configure --enable-autogen
+    make
+
+=== Documentation ==============================================================
+
+The manual page is generated in both html and roff formats.  Any web browser
+can be used to view the html manual.  The roff manual page can be formatted
+prior to installation via the following command:
+
+    nroff -man -t doc/jemalloc.3

-

-    The VERSION file is mandatory for successful configuration, and the
-    following steps are taken to assure its presence:
-    1) If --with-version=<major>.<minor>.<bugfix>-<nrev>-g<gid> is specified,
-       generate VERSION using the specified value.
-    2) If --with-version is not specified in either form and the source
-       directory is inside a git repository, try to generate VERSION via 'git
-       describe' invocations that pattern-match release tags.
-    3) If VERSION is missing, generate it with a bogus version:
-       0.0.0-0-g0000000000000000000000000000000000000000
-
-    Note that --with-version=VERSION bypasses (1) and (2), which simplifies

-    This makes it possible to use jemalloc at the same time as the system
-    allocator, or even to use multiple copies of jemalloc simultaneously.
-
-    By default, the prefix is "", except on OS X, where it is "je_".  On OS X,
-    jemalloc overlays the default malloc zone, but makes no attempt to actually
-    replace the "malloc", "calloc", etc. symbols.
-
-* `--without-export`
-
-    Don't export public APIs.  This can be useful when building jemalloc as a
-    static library, or to avoid exporting public APIs when using the zone
-    allocator on OSX.
-
-* `--with-private-namespace=<prefix>`
-
-    Prefix all library-private APIs with <prefix>je_.  For shared libraries,
-    symbol visibility mechanisms prevent these symbols from being exported, but
-    for static libraries, naming collisions are a real possibility.  By
-    default, <prefix> is empty, which results in a symbol prefix of je_ .
-
-* `--with-install-suffix=<suffix>`
-
-    Append <suffix> to the base name of all installed files, such that multiple
-    versions of jemalloc can coexist in the same installation directory.  For
-    example, libjemalloc.so.0 becomes libjemalloc<suffix>.so.0.
-
-* `--with-malloc-conf=<malloc_conf>`
-
-    Embed `<malloc_conf>` as a run-time options string that is processed prior to
-    the malloc_conf global variable, the /etc/malloc.conf symlink, and the
-    MALLOC_CONF environment variable.  For example, to change the default decay
-    time to 30 seconds:
-
-      --with-malloc-conf=decay_ms:30000
-
-* `--enable-debug`
-
-    Enable assertions and validation code.  This incurs a substantial
-    performance hit, but is very useful during application development.
-
-* `--disable-stats`
-
-    Disable statistics gathering functionality.  See the "opt.stats_print"
-    option documentation for usage details.
-
-* `--enable-prof`
-
-    Enable heap profiling and leak detection functionality.  See the "opt.prof"
-    option documentation for usage details.  When enabled, there are several
-    approaches to backtracing, and the configure script chooses the first one
-    in the following list that appears to function correctly:
-
-    + libunwind      (requires --enable-prof-libunwind)
-    + libgcc         (unless --disable-prof-libgcc)
-    + gcc intrinsics (unless --disable-prof-gcc)
-
-* `--enable-prof-libunwind`
-
-    Use the libunwind library (http://www.nongnu.org/libunwind/) for stack
-    backtracing.
-
-* `--disable-prof-libgcc`
-
-    Disable the use of libgcc's backtracing functionality.
-
-* `--disable-prof-gcc`
-
-    Disable the use of gcc intrinsics for backtracing.
-
-* `--with-static-libunwind=<libunwind.a>`
-
-    Statically link against the specified libunwind.a rather than dynamically
-    linking with -lunwind.
-
-* `--disable-fill`
-
-    Disable support for junk/zero filling of memory.  See the "opt.junk" and
-    "opt.zero" option documentation for usage details.
-
-* `--disable-zone-allocator`
-
-    Disable zone allocator for Darwin.  This means jemalloc won't be hooked as
-    the default allocator on OSX/iOS.
-
-* `--enable-utrace`
-
-    Enable utrace(2)-based allocation tracing.  This feature is not broadly
-    portable (FreeBSD has it, but Linux and OS X do not).
-
-* `--enable-xmalloc`
-
-    Enable support for optional immediate termination due to out-of-memory
-    errors, as is commonly implemented by "xmalloc" wrapper function for malloc.
-    See the "opt.xmalloc" option documentation for usage details.
-
-* `--enable-lazy-lock`
-
-    Enable code that wraps pthread_create() to detect when an application
-    switches from single-threaded to multi-threaded mode, so that it can avoid
-    mutex locking/unlocking operations while in single-threaded mode.  In
-    practice, this feature usually has little impact on performance unless
-    thread-specific caching is disabled.
-
-* `--disable-cache-oblivious`
-
-    Disable cache-oblivious large allocation alignment for large allocation
-    requests with no alignment constraints.  If this feature is disabled, all
-    large allocations are page-aligned as an implementation artifact, which can
-    severely harm CPU cache utilization.  However, the cache-oblivious layout
-    comes at the cost of one extra page per large allocation, which in the
-    most extreme case increases physical memory usage for the 16 KiB size class
-    to 20 KiB.
-
-* `--disable-syscall`
-
-    Disable use of syscall(2) rather than {open,read,write,close}(2).  This is
-    intended as a workaround for systems that place security limitations on
-    syscall(2).
-
-* `--disable-cxx`
-
-    Disable C++ integration.  This will cause new and delete operator
-    implementations to be omitted.
-
-* `--with-xslroot=<path>`
-
-    Specify where to find DocBook XSL stylesheets when building the
-    documentation.
-
-* `--with-lg-page=<lg-page>`
-
-    Specify the base 2 log of the allocator page size, which must in turn be at
-    least as large as the system page size.  By default the configure script
-    determines the host's page size and sets the allocator page size equal to
-    the system page size, so this option need not be specified unless the
-    system page size may change between configuration and execution, e.g. when
-    cross compiling.
-
-* `--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-hugepage=<lg-hugepage>`
-
-    Specify the base 2 log of the system huge page size.  This option is useful
-    when cross compiling, or when overriding the default for systems that do
-    not explicitly support huge pages.
-
-* `--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 for size classes smaller than the 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).
-
-* `--with-lg-vaddr=<lg-vaddr>`
-
-    Specify the number of significant virtual address bits.  By default, the
-    configure script attempts to detect virtual address size on those platforms
-    where it knows how, and picks a default otherwise.  This option may be
-    useful when cross-compiling.
-
-* `--disable-initial-exec-tls`
-
-    Disable the initial-exec TLS model for jemalloc's internal thread-local
-    storage (on those platforms that support explicit settings).  This can allow
-    jemalloc to be dynamically loaded after program startup (e.g. using dlopen).
-    Note that in this case, there will be two malloc implementations operating
-    in the same process, which will almost certainly result in confusing runtime
-    crashes if pointers leak from one implementation to the other.
-
-The following environment variables (not a definitive list) impact configure's
-behavior:
-
-* `CFLAGS="?"`
-* `CXXFLAGS="?"`
-
-    Pass these flags to the C/C++ compiler.  Any flags set by the configure
-    script are prepended, which means explicitly set flags generally take
-    precedence.  Take care when specifying flags such as -Werror, because
-    configure tests may be affected in undesirable ways.
-
-* `EXTRA_CFLAGS="?"`
-* `EXTRA_CXXFLAGS="?"`
-
-    Append these flags to CFLAGS/CXXFLAGS, without passing them to the
-    compiler(s) during configuration.  This makes it possible to add flags such
-    as -Werror, while allowing the configure script to determine what other
-    flags are appropriate for the specified configuration.
-
-* `CPPFLAGS="?"`
-
-    Pass these flags to the C preprocessor.  Note that CFLAGS is not passed to
-    'cpp' when 'configure' is looking for include files, so you must use
-    CPPFLAGS instead if you need to help 'configure' find header files.
-
-* `LD_LIBRARY_PATH="?"`
-
-    'ld' uses this colon-separated list to find libraries.
-
-* `LDFLAGS="?"`
-
-    Pass these flags when linking.
-
-* `PATH="?"`
-
-    'configure' uses this to find programs.
-
-In some cases it may be necessary to work around configuration results that do
-not match reality.  For example, Linux 4.5 added support for the MADV_FREE flag
-to madvise(2), which can cause problems if building on a host with MADV_FREE
-support and deploying to a target without.  To work around this, use a cache
-file to override the relevant configuration variable defined in configure.ac,
-e.g.:
-
-    echo "je_cv_madv_free=no" > config.cache && ./configure -C
-
-
-## Advanced compilation
-
-To build only parts of jemalloc, use the following targets:
-
-    build_lib_shared
-    build_lib_static
-    build_lib
-    build_doc_html
-    build_doc_man
-    build_doc
-
-To install only parts of jemalloc, use the following targets:
-
-    install_bin
-    install_include
-    install_lib_shared
-    install_lib_static
-    install_lib_pc
-    install_lib
-    install_doc_html
-    install_doc_man
-    install_doc
-
-To clean up build results to varying degrees, use the following make targets:
-
-    clean
-    distclean
-    relclean
-
-
-## Advanced installation
-
-Optionally, define make variables when invoking make, including (not
-exclusively):
-
-* `INCLUDEDIR="?"`
-
-    Use this as the installation prefix for header files.
-
-* `LIBDIR="?"`
-
-    Use this as the installation prefix for libraries.
-
-* `MANDIR="?"`
-
-    Use this as the installation prefix for man pages.
-
-* `DESTDIR="?"`
-
-    Prepend DESTDIR to INCLUDEDIR, LIBDIR, DATADIR, and MANDIR.  This is useful
-    when installing to a different path than was specified via --prefix.
-
-* `CC="?"`
-
-    Use this to invoke the C compiler.
-
-* `CFLAGS="?"`
-
-    Pass these flags to the compiler.
-
-* `CPPFLAGS="?"`
-
-    Pass these flags to the C preprocessor.
-
-* `LDFLAGS="?"`
-
-    Pass these flags when linking.
-
-* `PATH="?"`
-
-    Use this to search for programs used during configuration and building.
-
-
-## Development
-
-If you intend to make non-trivial changes to jemalloc, use the 'autogen.sh'
-script rather than 'configure'.  This re-generates 'configure', enables
-configuration dependency rules, and enables re-generation of automatically
-generated source files.
-
-The build system supports using an object directory separate from the source
-tree.  For example, you can create an 'obj' directory, and from within that
-directory, issue configuration and build commands:
-
-    autoconf
-    mkdir obj
-    cd obj
-    ../configure --enable-autogen
-    make
-
-
-## Documentation
-
-The manual page is generated in both html and roff formats.  Any web browser
-can be used to view the html manual.  The roff manual page can be formatted
-prior to installation via the following command:
-
-    nroff -man -t doc/jemalloc.3

-jemalloc is a general purpose malloc(3) implementation that emphasizes
-fragmentation avoidance and scalable concurrency support.  jemalloc first came
-into use as the FreeBSD libc allocator in 2005, and since then it has found its
-way into numerous applications that rely on its predictable behavior.  In 2010
-jemalloc development efforts broadened to include developer support features
-such as heap profiling and extensive monitoring/tuning hooks.  Modern jemalloc
-releases continue to be integrated back into FreeBSD, and therefore versatility
-remains critical.  Ongoing development efforts trend toward making jemalloc
-among the best allocators for a broad range of demanding applications, and
-eliminating/mitigating weaknesses that have practical repercussions for real
-world applications.
+jemalloc is a general-purpose scalable concurrent malloc(3) implementation.
+This distribution is a "portable" implementation that currently targets
+FreeBSD, Linux, Apple OS X, and MinGW.  jemalloc is included as the default
+allocator in the FreeBSD and NetBSD operating systems, and it is used by the
+Mozilla Firefox web browser on Microsoft Windows-related platforms.  Depending
+on your needs, one of the other divergent versions may suit your needs better
+than this distribution.

-This document summarizes the common approaches for performance fine tuning with
-jemalloc (as of 5.1.0).  The default configuration of jemalloc tends to work
-reasonably well in practice, and most applications should not have to tune any
-options. However, in order to cover a wide range of applications and avoid
-pathological cases, the default setting is sometimes kept conservative and
-suboptimal, even for many common workloads.  When jemalloc is properly tuned for
-a specific application / workload, it is common to improve system level metrics
-by a few percent, or make favorable trade-offs.

-[malloc_conf](http://jemalloc.net/jemalloc.3.html#tuning).
-
-* [background_thread](http://jemalloc.net/jemalloc.3.html#background_thread)
-
-    Enabling jemalloc background threads generally improves the tail latency for
-    application threads, since unused memory purging is shifted to the dedicated
-    background threads.  In addition, unintended purging delay caused by
-    application inactivity is avoided with background threads.
-
-    Suggested: `background_thread:true` when jemalloc managed threads can be
-    allowed.
-
-* [metadata_thp](http://jemalloc.net/jemalloc.3.html#opt.metadata_thp)
-
-    Allowing jemalloc to utilize transparent huge pages for its internal
-    metadata usually reduces TLB misses significantly, especially for programs
-    with large memory footprint and frequent allocation / deallocation
-    activities.  Metadata memory usage may increase due to the use of huge
-    pages.
-
-    Suggested for allocation intensive programs: `metadata_thp:auto` or
-    `metadata_thp:always`, which is expected to improve CPU utilization at a
-    small memory cost.
-
-* [dirty_decay_ms](http://jemalloc.net/jemalloc.3.html#opt.dirty_decay_ms) and
-  [muzzy_decay_ms](http://jemalloc.net/jemalloc.3.html#opt.muzzy_decay_ms)
-
-    Decay time determines how fast jemalloc returns unused pages back to the
-    operating system, and therefore provides a fairly straightforward trade-off
-    between CPU and memory usage.  Shorter decay time purges unused pages faster
-    to reduces memory usage (usually at the cost of more CPU cycles spent on
-    purging), and vice versa.
-
-    Suggested: tune the values based on the desired trade-offs.
-
-* [narenas](http://jemalloc.net/jemalloc.3.html#opt.narenas)
-
-    By default jemalloc uses multiple arenas to reduce internal lock contention.
-    However high arena count may also increase overall memory fragmentation,
-    since arenas manage memory independently.  When high degree of parallelism
-    is not expected at the allocator level, lower number of arenas often
-    improves memory usage.
-
-    Suggested: if low parallelism is expected, try lower arena count while
-    monitoring CPU and memory usage.
-
-* [percpu_arena](http://jemalloc.net/jemalloc.3.html#opt.percpu_arena)
-
-    Enable dynamic thread to arena association based on running CPU.  This has
-    the potential to improve locality, e.g. when thread to CPU affinity is
-    present.
-    
-    Suggested: try `percpu_arena:percpu` or `percpu_arena:phycpu` if
-    thread migration between processors is expected to be infrequent.
-
-Examples:
-
-* High resource consumption application, prioritizing CPU utilization:
-
-    `background_thread:true,metadata_thp:auto` combined with relaxed decay time
-    (increased `dirty_decay_ms` and / or `muzzy_decay_ms`,
-    e.g. `dirty_decay_ms:30000,muzzy_decay_ms:30000`).
-
-* High resource consumption application, prioritizing memory usage:
-
-    `background_thread:true` combined with shorter decay time (decreased
-    `dirty_decay_ms` and / or `muzzy_decay_ms`,
-    e.g. `dirty_decay_ms:5000,muzzy_decay_ms:5000`), and lower arena count
-    (e.g. number of CPUs).
-
-* Low resource consumption application:
-
-    `narenas:1,lg_tcache_max:13` combined with shorter decay time (decreased
-    `dirty_decay_ms` and / or `muzzy_decay_ms`,e.g.
-    `dirty_decay_ms:1000,muzzy_decay_ms:0`).
-
-* Extremely conservative -- minimize memory usage at all costs, only suitable when
-allocation activity is very rare:
-
-    `narenas:1,tcache:false,dirty_decay_ms:0,muzzy_decay_ms:0`
-
-Note that it is recommended to combine the options with `abort_conf:true` which
-aborts immediately on illegal options.
-
-## Beyond runtime options
-
-In addition to the runtime options, there are a number of programmatic ways to
-improve application performance with jemalloc.
-
-* [Explicit arenas](http://jemalloc.net/jemalloc.3.html#arenas.create)
-
-    Manually created arenas can help performance in various ways, e.g. by
-    managing locality and contention for specific usages.  For example,
-    applications can explicitly allocate frequently accessed objects from a
-    dedicated arena with
-    [mallocx()](http://jemalloc.net/jemalloc.3.html#MALLOCX_ARENA) to improve
-    locality.  In addition, explicit arenas often benefit from individually
-    tuned options, e.g. relaxed [decay
-    time](http://jemalloc.net/jemalloc.3.html#arena.i.dirty_decay_ms) if
-    frequent reuse is expected.
-
-* [Extent hooks](http://jemalloc.net/jemalloc.3.html#arena.i.extent_hooks)
-
-    Extent hooks allow customization for managing underlying memory.  One use
-    case for performance purpose is to utilize huge pages -- for example,
-    [HHVM](https://github.com/facebook/hhvm/blob/master/hphp/util/alloc.cpp)
-    uses explicit arenas with customized extent hooks to manage 1GB huge pages
-    for frequently accessed data, which reduces TLB misses significantly.
-
-* [Explicit thread-to-arena
-  binding](http://jemalloc.net/jemalloc.3.html#thread.arena)
-
-    It is common for some threads in an application to have different memory
-    access / allocation patterns.  Threads with heavy workloads often benefit
-    from explicit binding, e.g. binding very active threads to dedicated arenas
-    may reduce contention at the allocator level.
