-**This Readme reflects the latest changed in the master branch. See [v0.13.3](https://github.com/redis/hiredis/tree/v0.13.3) for the Readme and documentation for the latest release.** - -# 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. - -## AUTHORS - -Hiredis was written by Salvatore Sanfilippo (antirez at gmail) and -Pieter Noordhuis (pcnoordhuis at gmail) and is released under the BSD license. -Hiredis is currently maintained by Matt Stancliff (matt at genges dot com) and -Jan-Erik Rediger (janerik at fnordig dot com) diff --git a/deps/hiredis/adapters/ae.h b/deps/hiredis/adapters/ae.h deleted file mode 100644 index 5c551c2ed..000000000 --- a/deps/hiredis/adapters/ae.h +++ /dev/null @@ -1,127 +0,0 @@ -/* - * Copyright (c) 2010-2011, Pieter Noordhuis <pcnoordhuis at gmail dot com> - * - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions are met: - * - * * Redistributions of source code must retain the above copyright notice, - * this list of conditions and the following disclaimer. - * * Redistributions in binary form must reproduce the above copyright - * notice, this list of conditions and the following disclaimer in the - * documentation and/or other materials provided with the distribution. - * * Neither the name of Redis nor the names of its contributors may be used - * to endorse or promote products derived from this software without - * specific prior written permission. - * - * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" - * AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE - * IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE - * ARE DISCLAIMED.
