-### 1.0.0 (unreleased)
-
-**BREAKING CHANGES**:
-
-* Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now
-  protocol errors. This is consistent with the RESP specification. On 32-bit
-  platforms, the upper bound is lowered to `SIZE_MAX`.
-
-* Change `redisReply.len` to `size_t`, as it denotes the the size of a string
-
-  User code should compare this to `size_t` values as well.  If it was used to
-  compare to other values, casting might be necessary or can be removed, if
-  casting was applied before.
-
-### 0.x.x (unreleased)
-**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.
-
-* `redisReplyObjectFunctions.createArray` now takes `size_t` for its length parameter.
-

-* Don't send negative values to `__redisAsyncCommand` (Frederik Deweerdt [706129])
-* Fix leak if setsockopt fails (Frederik Deweerdt [e21c9c])
-* Fix libevent leak (zfz [515228])
-* Clean up GCC warning (Ichito Nagata [2ec774])
-* Keep track of errno in `__redisSetErrorFromErrno()` as snprintf may use it (Jin Qing [25cd88])
-* Solaris compilation fix (Donald Whyte [41b07d])
-* Reorder linker arguments when building examples (Tustfarm-heart [06eedd])
-* Keep track of subscriptions in case of rapid subscribe/unsubscribe (Hyungjin Kim [073dc8, be76c5, d46999])

-* Update libevent (Chris Xin [386802])
-* Change sds.h for building in C++ projects (Ali Volkan ATLI [f5b32e])
-* Use proper format specifier in redisFormatSdsCommandArgv (Paulino Huerta, Jan-Erik Rediger [360a06, 8655a6])
-* Better handling of NULL reply in example code (Jan-Erik Rediger [1b8ed3])
-* Prevent overflow when formatting an error (Jan-Erik Rediger [0335cb])
-* Compatibility fix for strerror_r (Tom Lee [bb1747])
-* Properly detect integer parse/overflow errors (Justin Brewer [93421f])
-* Adds CI for Windows and cygwin fixes (owent, [6c53d6, 6c3e40])
-* Catch a buffer overflow when formatting the error message
-* Import latest upstream sds. This breaks applications that are linked against the old hiredis v0.13
-* Fix warnings, when compiled with -Wshadow
-* Make hiredis compile in Cygwin on Windows, now CI-tested
-* Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now
-  protocol errors. This is consistent with the RESP specification. On 32-bit
-  platforms, the upper bound is lowered to `SIZE_MAX`.
-
-* Remove backwards compatibility macro's
-
-This removes the following old function aliases, use the new name now:
-
-| Old                         | New                    |
-| --------------------------- | ---------------------- |
-| redisReplyReaderCreate      | redisReaderCreate      |
-| redisReplyReaderCreate      | redisReaderCreate      |
-| redisReplyReaderFree        | redisReaderFree        |
-| redisReplyReaderFeed        | redisReaderFeed        |
-| redisReplyReaderGetReply    | redisReaderGetReply    |
-| redisReplyReaderSetPrivdata | redisReaderSetPrivdata |
-| redisReplyReaderGetObject   | redisReaderGetObject   |
-| redisReplyReaderGetError    | redisReaderGetError    |
-
-* The `DEBUG` variable in the Makefile was renamed to `DEBUG_FLAGS`
-
-Previously it broke some builds for people that had `DEBUG` set to some arbitrary value,
-due to debugging other software.
-By renaming we avoid unintentional name clashes.
-
-Simply rename `DEBUG` to `DEBUG_FLAGS` in your environment to make it working again.
-
-### 0.13.3 (2015-09-16)
-
-* Revert "Clear `REDIS_CONNECTED` flag when connection is closed".
-* Make tests pass on FreeBSD (Thanks, Giacomo Olgeni)
-
-
-If the `REDIS_CONNECTED` flag is cleared,
-the async onDisconnect callback function will never be called.
-This causes problems as the disconnect is never reported back to the user.
-
-### 0.13.2 (2015-08-25)
-
-* Prevent crash on pending replies in async code (Thanks, @switch-st)
-* Clear `REDIS_CONNECTED` flag when connection is closed (Thanks, Jerry Jacobs)
-* Add MacOS X addapter (Thanks, @dizzus)
-* Add Qt adapter (Thanks, Pietro Cerutti)
-* Add Ivykis adapter (Thanks, Gergely Nagy)
-
-All adapters are provided as is and are only tested where possible.
-
-### 0.13.1 (2015-05-03)
-
-This is a bug fix release.
-The new `reconnect` method introduced new struct members, which clashed with pre-defined names in pre-C99 code.
-Another commit forced C99 compilation just to make it work, but of course this is not desirable for outside projects.
-Other non-C99 code can now use hiredis as usual again.
-Sorry for the inconvenience.
-
-* Fix memory leak in async reply handling (Salvatore Sanfilippo)
-* Rename struct member to avoid name clash with pre-c99 code (Alex Balashov, ncopa)
-
-### 0.13.0 (2015-04-16)
-
-This release adds a minimal Windows compatibility layer.
-The parser, standalone since v0.12.0, can now be compiled on Windows
-(and thus used in other client libraries as well)
-
-* Windows compatibility layer for parser code (tzickel)
-* Properly escape data printed to PKGCONF file (Dan Skorupski)
-* Fix tests when assert() undefined (Keith Bennett, Matt Stancliff)
-* Implement a reconnect method for the client context, this changes the structure of `redisContext` (Aaron Bedra)
-
-### 0.12.1 (2015-01-26)
-
-* Fix `make install`: DESTDIR support, install all required files, install PKGCONF in proper location
-* Fix `make test` as 32 bit build on 64 bit platform
-
-### 0.12.0 (2015-01-22)
-
-* Add optional KeepAlive support
-
-* Try again on EINTR errors
-
-* Add libuv adapter
-
-* Add IPv6 support
-
-* Remove possibility of multiple close on same fd
-
-* Add ability to bind source address on connect
-
-* Add redisConnectFd() and redisFreeKeepFd()
-
-* Fix getaddrinfo() memory leak
-
-* Free string if it is unused (fixes memory leak)
-
-* Improve redisAppendCommandArgv performance 2.5x
-
-* Add support for SO_REUSEADDR
-
-* Fix redisvFormatCommand format parsing
-
-* Add GLib 2.0 adapter
-
-* Refactor reading code into read.c
-
-* Fix errno error buffers to not clobber errors
-
-* Generate pkgconf during build
-
-* Silence _BSD_SOURCE warnings
-
-* Improve digit counting for multibulk creation
-
-
-### 0.11.0
-
-* Increase the maximum multi-bulk reply depth to 7.
-
-* Increase the read buffer size from 2k to 16k.
-
-* Use poll(2) instead of select(2) to support large fds (>= 1024).
-
-### 0.10.1
-
-* Makefile overhaul. Important to check out if you override one or more
-  variables using environment variables or via arguments to the "make" tool.
-
-* Issue #45: Fix potential memory leak for a multi bulk reply with 0 elements
-  being created by the default reply object functions.
-
-* Issue #43: Don't crash in an asynchronous context when Redis returns an error
-  reply after the connection has been made (this happens when the maximum
-  number of connections is reached).
-
-### 0.10.0
-
-* See commit log.

-# HIREDIS
-
-Hiredis is a minimalistic C client library for the [Redis](http://redis.io/) database.
-
-It is minimalistic because it just adds minimal support for the protocol, but
-at the same time it uses a high level printf-alike API in order to make it
-much higher level than otherwise suggested by its minimal code base and the
-lack of explicit bindings for every Redis command.
-
-Apart from supporting sending commands and receiving replies, it comes with
-a reply parser that is decoupled from the I/O layer. It
-is a stream parser designed for easy reusability, which can for instance be used
-in higher level language bindings for efficient reply parsing.
-
-Hiredis only supports the binary-safe Redis protocol, so you can use it with any
-Redis version >= 1.2.0.
-
-The library comes with multiple APIs. There is the
-*synchronous API*, the *asynchronous API* and the *reply parsing API*.
-
-## Upgrading to `1.0.0`
-
-Version 1.0.0 marks a stable release of hiredis.
-It includes some minor breaking changes, mostly to make the exposed API more uniform and self-explanatory.
-It also bundles the updated `sds` library, to sync up with upstream and Redis.
-For most applications a recompile against the new hiredis should be enough.
-For code changes see the [Changelog](CHANGELOG.md).
-
-## Upgrading from `<0.9.0`
-
-Version 0.9.0 is a major overhaul of hiredis in every aspect. However, upgrading existing
-code using hiredis should not be a big pain. The key thing to keep in mind when
-upgrading is that hiredis >= 0.9.0 uses a `redisContext*` to keep state, in contrast to
-the stateless 0.0.1 that only has a file descriptor to work with.
-
-## Synchronous API
-
-To consume the synchronous API, there are only a few function calls that need to be introduced:
-
-```c
-redisContext *redisConnect(const char *ip, int port);
-void *redisCommand(redisContext *c, const char *format, ...);
-void freeReplyObject(void *reply);
-```
-
-### Connecting
-
-The function `redisConnect` is used to create a so-called `redisContext`. The
-context is where Hiredis holds state for a connection. The `redisContext`
-struct has an integer `err` field that is non-zero when the connection is in
-an error state. The field `errstr` will contain a string with a description of
-the error. More information on errors can be found in the **Errors** section.
-After trying to connect to Redis using `redisConnect` you should
-check the `err` field to see if establishing the connection was successful:
-```c
-redisContext *c = redisConnect("127.0.0.1", 6379);
-if (c == NULL || c->err) {
-    if (c) {
-        printf("Error: %s\n", c->errstr);
-        // handle error
-    } else {
-        printf("Can't allocate redis context\n");
-    }
-}
-```
-
-*Note: A `redisContext` is not thread-safe.*
-
-### Sending commands
-
-There are several ways to issue commands to Redis. The first that will be introduced is
-`redisCommand`. This function takes a format similar to printf. In the simplest form,
-it is used like this:
-```c
-reply = redisCommand(context, "SET foo bar");
-```
-
-The specifier `%s` interpolates a string in the command, and uses `strlen` to
-determine the length of the string:
-```c
-reply = redisCommand(context, "SET foo %s", value);
-```
-When you need to pass binary safe strings in a command, the `%b` specifier can be
-used. Together with a pointer to the string, it requires a `size_t` length argument
-of the string:
-```c
-reply = redisCommand(context, "SET foo %b", value, (size_t) valuelen);
-```
-Internally, Hiredis splits the command in different arguments and will
-convert it to the protocol used to communicate with Redis.
-One or more spaces separates arguments, so you can use the specifiers
-anywhere in an argument:
-```c
-reply = redisCommand(context, "SET key:%s %s", myid, value);
-```
-
-### Using replies
-
-The return value of `redisCommand` holds a reply when the command was
-successfully executed. When an error occurs, the return value is `NULL` and
-the `err` field in the context will be set (see section on **Errors**).
-Once an error is returned the context cannot be reused and you should set up
-a new connection.
-
-The standard replies that `redisCommand` are of the type `redisReply`. The
-`type` field in the `redisReply` should be used to test what kind of reply
-was received:
-
-* **`REDIS_REPLY_STATUS`**:
-    * The command replied with a status reply. The status string can be accessed using `reply->str`.
-      The length of this string can be accessed using `reply->len`.
-
-* **`REDIS_REPLY_ERROR`**:
-    *  The command replied with an error. The error string can be accessed identical to `REDIS_REPLY_STATUS`.
-
-* **`REDIS_REPLY_INTEGER`**:
-    * The command replied with an integer. The integer value can be accessed using the
-      `reply->integer` field of type `long long`.
-
-* **`REDIS_REPLY_NIL`**:
-    * The command replied with a **nil** object. There is no data to access.
-
-* **`REDIS_REPLY_STRING`**:
-    * A bulk (string) reply. The value of the reply can be accessed using `reply->str`.
-      The length of this string can be accessed using `reply->len`.
-
-* **`REDIS_REPLY_ARRAY`**:
-    * A multi bulk reply. The number of elements in the multi bulk reply is stored in
-      `reply->elements`. Every element in the multi bulk reply is a `redisReply` object as well
-      and can be accessed via `reply->element[..index..]`.
-      Redis may reply with nested arrays but this is fully supported.
-
-Replies should be freed using the `freeReplyObject()` function.
-Note that this function will take care of freeing sub-reply objects
-contained in arrays and nested arrays, so there is no need for the user to
-free the sub replies (it is actually harmful and will corrupt the memory).
-
-**Important:** the current version of hiredis (0.10.0) frees replies when the
-asynchronous API is used. This means you should not call `freeReplyObject` when
-you use this API. The reply is cleaned up by hiredis _after_ the callback
-returns. This behavior will probably change in future releases, so make sure to
-keep an eye on the changelog when upgrading (see issue #39).
-
-### Cleaning up
-
-To disconnect and free the context the following function can be used:
-```c
-void redisFree(redisContext *c);
-```
-This function immediately closes the socket and then frees the allocations done in
-creating the context.
-
-### Sending commands (cont'd)
-
-Together with `redisCommand`, the function `redisCommandArgv` can be used to issue commands.
-It has the following prototype:
-```c
-void *redisCommandArgv(redisContext *c, int argc, const char **argv, const size_t *argvlen);
-```
-It takes the number of arguments `argc`, an array of strings `argv` and the lengths of the
-arguments `argvlen`. For convenience, `argvlen` may be set to `NULL` and the function will
-use `strlen(3)` on every argument to determine its length. Obviously, when any of the arguments
-need to be binary safe, the entire array of lengths `argvlen` should be provided.
-
-The return value has the same semantic as `redisCommand`.
-
-### Pipelining
-
-To explain how Hiredis supports pipelining in a blocking connection, there needs to be
-understanding of the internal execution flow.
-
-When any of the functions in the `redisCommand` family is called, Hiredis first formats the
-command according to the Redis protocol. The formatted command is then put in the output buffer
-of the context. This output buffer is dynamic, so it can hold any number of commands.
-After the command is put in the output buffer, `redisGetReply` is called. This function has the
-following two execution paths:
-
-1. The input buffer is non-empty:
-    * Try to parse a single reply from the input buffer and return it
-    * If no reply could be parsed, continue at *2*
-2. The input buffer is empty:
-    * Write the **entire** output buffer to the socket
-    * Read from the socket until a single reply could be parsed
-
-The function `redisGetReply` is exported as part of the Hiredis API and can be used when a reply
-is expected on the socket. To pipeline commands, the only things that needs to be done is
-filling up the output buffer. For this cause, two commands can be used that are identical
-to the `redisCommand` family, apart from not returning a reply:
-```c
-void redisAppendCommand(redisContext *c, const char *format, ...);
-void redisAppendCommandArgv(redisContext *c, int argc, const char **argv, const size_t *argvlen);
-```
-After calling either function one or more times, `redisGetReply` can be used to receive the
-subsequent replies. The return value for this function is either `REDIS_OK` or `REDIS_ERR`, where
-the latter means an error occurred while reading a reply. Just as with the other commands,
-the `err` field in the context can be used to find out what the cause of this error is.
-
-The following examples shows a simple pipeline (resulting in only a single call to `write(2)` and
-a single call to `read(2)`):
-```c
-redisReply *reply;
-redisAppendCommand(context,"SET foo bar");
-redisAppendCommand(context,"GET foo");
-redisGetReply(context,&reply); // reply for SET
-freeReplyObject(reply);
-redisGetReply(context,&reply); // reply for GET
-freeReplyObject(reply);
-```
-This API can also be used to implement a blocking subscriber:
-```c
-reply = redisCommand(context,"SUBSCRIBE foo");
-freeReplyObject(reply);
-while(redisGetReply(context,&reply) == REDIS_OK) {
-    // consume message
-    freeReplyObject(reply);
-}
-```
-### Errors
-
-When a function call is not successful, depending on the function either `NULL` or `REDIS_ERR` is
-returned. The `err` field inside the context will be non-zero and set to one of the
-following constants:
-
-* **`REDIS_ERR_IO`**:
-    There was an I/O error while creating the connection, trying to write
-    to the socket or read from the socket. If you included `errno.h` in your
-    application, you can use the global `errno` variable to find out what is
-    wrong.
-
-* **`REDIS_ERR_EOF`**:
-    The server closed the connection which resulted in an empty read.
-
-* **`REDIS_ERR_PROTOCOL`**:
-    There was an error while parsing the protocol.
-
-* **`REDIS_ERR_OTHER`**:
-    Any other error. Currently, it is only used when a specified hostname to connect
-    to cannot be resolved.
-
-In every case, the `errstr` field in the context will be set to hold a string representation
-of the error.
-
-## Asynchronous API
-
-Hiredis comes with an asynchronous API that works easily with any event library.
-Examples are bundled that show using Hiredis with [libev](http://software.schmorp.de/pkg/libev.html)
-and [libevent](http://monkey.org/~provos/libevent/).
-
-### Connecting
-
-The function `redisAsyncConnect` can be used to establish a non-blocking connection to
-Redis. It returns a pointer to the newly created `redisAsyncContext` struct. The `err` field
-should be checked after creation to see if there were errors creating the connection.
-Because the connection that will be created is non-blocking, the kernel is not able to
-instantly return if the specified host and port is able to accept a connection.
-
-*Note: A `redisAsyncContext` is not thread-safe.*
-
-```c
-redisAsyncContext *c = redisAsyncConnect("127.0.0.1", 6379);
-if (c->err) {
-    printf("Error: %s\n", c->errstr);
-    // handle error
-}
-```
-
-The asynchronous context can hold a disconnect callback function that is called when the
-connection is disconnected (either because of an error or per user request). This function should
-have the following prototype:
-```c
-void(const redisAsyncContext *c, int status);
-```
-On a disconnect, the `status` argument is set to `REDIS_OK` when disconnection was initiated by the
-user, or `REDIS_ERR` when the disconnection was caused by an error. When it is `REDIS_ERR`, the `err`
-field in the context can be accessed to find out the cause of the error.
-
-The context object is always freed after the disconnect callback fired. When a reconnect is needed,
-the disconnect callback is a good point to do so.
-
-Setting the disconnect callback can only be done once per context. For subsequent calls it will
-return `REDIS_ERR`. The function to set the disconnect callback has the following prototype:
-```c
-int redisAsyncSetDisconnectCallback(redisAsyncContext *ac, redisDisconnectCallback *fn);
-```
-`ac->data` may be used to pass user data to this callback, the same can be done for redisConnectCallback.
-### Sending commands and their callbacks
-
-In an asynchronous context, commands are automatically pipelined due to the nature of an event loop.
-Therefore, unlike the synchronous API, there is only a single way to send commands.
-Because commands are sent to Redis asynchronously, issuing a command requires a callback function
-that is called when the reply is received. Reply callbacks should have the following prototype:
-```c
-void(redisAsyncContext *c, void *reply, void *privdata);
-```
-The `privdata` argument can be used to curry arbitrary data to the callback from the point where
-the command is initially queued for execution.
-
-The functions that can be used to issue commands in an asynchronous context are:
-```c
-int redisAsyncCommand(
-  redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
-  const char *format, ...);
-int redisAsyncCommandArgv(
-  redisAsyncContext *ac, redisCallbackFn *fn, void *privdata,
-  int argc, const char **argv, const size_t *argvlen);
-```
-Both functions work like their blocking counterparts. The return value is `REDIS_OK` when the command
-was successfully added to the output buffer and `REDIS_ERR` otherwise. Example: when the connection
-is being disconnected per user-request, no new commands may be added to the output buffer and `REDIS_ERR` is
-returned on calls to the `redisAsyncCommand` family.
-
-If the reply for a command with a `NULL` callback is read, it is immediately freed. When the callback
-for a command is non-`NULL`, the memory is freed immediately following the callback: the reply is only
-valid for the duration of the callback.
-
-All pending callbacks are called with a `NULL` reply when the context encountered an error.
-
-### Disconnecting
-
-An asynchronous connection can be terminated using:
-```c
-void redisAsyncDisconnect(redisAsyncContext *ac);
-```
-When this function is called, the connection is **not** immediately terminated. Instead, new
-commands are no longer accepted and the connection is only terminated when all pending commands
-have been written to the socket, their respective replies have been read and their respective
-callbacks have been executed. After this, the disconnection callback is executed with the
-`REDIS_OK` status and the context object is freed.
-
-### Hooking it up to event library *X*
-
-There are a few hooks that need to be set on the context object after it is created.
-See the `adapters/` directory for bindings to *libev* and *libevent*.
-
-## Reply parsing API
-
-Hiredis comes with a reply parsing API that makes it easy for writing higher
-level language bindings.
-
-The reply parsing API consists of the following functions:
-```c
-redisReader *redisReaderCreate(void);
-void redisReaderFree(redisReader *reader);
-int redisReaderFeed(redisReader *reader, const char *buf, size_t len);
-int redisReaderGetReply(redisReader *reader, void **reply);
-```
-The same set of functions are used internally by hiredis when creating a
-normal Redis context, the above API just exposes it to the user for a direct
-usage.
-
-### Usage
-
-The function `redisReaderCreate` creates a `redisReader` structure that holds a
-buffer with unparsed data and state for the protocol parser.
-
-Incoming data -- most likely from a socket -- can be placed in the internal
-buffer of the `redisReader` using `redisReaderFeed`. This function will make a
-copy of the buffer pointed to by `buf` for `len` bytes. This data is parsed
-when `redisReaderGetReply` is called. This function returns an integer status
-and a reply object (as described above) via `void **reply`. The returned status
-can be either `REDIS_OK` or `REDIS_ERR`, where the latter means something went
-wrong (either a protocol error, or an out of memory error).
-
-The parser limits the level of nesting for multi bulk payloads to 7. If the
-multi bulk nesting level is higher than this, the parser returns an error.
-
-### Customizing replies
-
-The function `redisReaderGetReply` creates `redisReply` and makes the function
-argument `reply` point to the created `redisReply` variable. For instance, if
-the response of type `REDIS_REPLY_STATUS` then the `str` field of `redisReply`
-will hold the status as a vanilla C string. However, the functions that are
-responsible for creating instances of the `redisReply` can be customized by
-setting the `fn` field on the `redisReader` struct. This should be done
-immediately after creating the `redisReader`.
-
-For example, [hiredis-rb](https://github.com/pietern/hiredis-rb/blob/master/ext/hiredis_ext/reader.c)
-uses customized reply object functions to create Ruby objects.
-
-### Reader max buffer
-
-Both when using the Reader API directly or when using it indirectly via a
-normal Redis context, the redisReader structure uses a buffer in order to
-accumulate data from the server.
-Usually this buffer is destroyed when it is empty and is larger than 16
-KiB in order to avoid wasting memory in unused buffers
-
-However when working with very big payloads destroying the buffer may slow
-down performances considerably, so it is possible to modify the max size of
-an idle buffer changing the value of the `maxbuf` field of the reader structure
-to the desired value. The special value of 0 means that there is no maximum
-value for an idle buffer, so the buffer will never get freed.
-
-For instance if you have a normal Redis context you can set the maximum idle
-buffer to zero (unlimited) just with:
-```c
-context->reader->maxbuf = 0;
-```
-This should be done only in order to maximize performances when working with
-large payloads. The context should be set back to `REDIS_READER_MAX_BUF` again
-as soon as possible in order to prevent allocation of useless memory.
