One for connecting, and one for commands. If you're presently using `options->timeout` you will need to change it to use `options->connect_timeout`. (See [example](https://github.com/redis/hiredis/commit/38b5ae543f5c99eb4ccabbe277770fc6bc81226f#diff-86ba39d37aa829c8c82624cce4f049fbL36)) + +* Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now protocol errors.

Status](https://travis-ci.org/redis/hiredis.png)](https://travis-ci.org/redis/hiredis) + +**This Readme reflects the latest changed in the master branch. See [v1.0.0](https://github.com/redis/hiredis/tree/v1.0.0) for the Readme and documentation for the latest release ([API/ABI history](https://abi-laboratory.pro/?view=timeline&l=hiredis)).** + +# HIREDIS + +Hiredis is a minimalistic C client library for the [Redis](http://redis.io/) database. + +It is minimalistic because it just adds minimal support for the protocol, but +at the same time it uses a high level printf-alike API in order to make it +much higher level than otherwise suggested by its minimal code base and the +lack of explicit bindings for every Redis command. + +Apart from supporting sending commands and receiving replies, it comes with +a reply parser that is decoupled from the I/O layer. It +is a stream parser designed for easy reusability, which can for instance be used +in higher level language bindings for efficient reply parsing. + +Hiredis only supports the binary-safe Redis protocol, so you can use it with any +Redis version >= 1.2.0. + +The library comes with multiple APIs. There is the +*synchronous API*, the *asynchronous API* and the *reply parsing API*. + +## Upgrading to `1.0.2` + +NOTE: v1.0.1 erroneously bumped SONAME, which is why it is skipped here. + +Version 1.0.2 is simply 1.0.0 with a fix for [CVE-2021-32765](https://github.com/redis/hiredis/security/advisories/GHSA-hfm9-39pp-55p2). They are otherwise identical. + +## Upgrading to `1.0.0` + +Version 1.0.0 marks the first stable release of Hiredis. +It includes some minor breaking changes, mostly to make the exposed API more uniform and self-explanatory. +It also bundles the updated `sds` library, to sync up with upstream and Redis. +For code changes see the [Changelog](CHANGELOG.md). + +_Note: As described below, a few member names have been changed but most applications should be able to upgrade with minor code changes and recompiling._ + +## IMPORTANT: Breaking changes from `0.14.1` -> `1.0.0` + +* `redisContext` has two additional members (`free_privdata`, and `privctx`). +* `redisOptions.timeout` has been renamed to `redisOptions.connect_timeout`, and we've added `redisOptions.command_timeout`. +* `redisReplyObjectFunctions.createArray` now takes `size_t` instead of `int` for its length parameter. + +## IMPORTANT: Breaking changes when upgrading from 0.13.x -> 0.14.x + +Bulk and multi-bulk lengths less than -1 or greater than `LLONG_MAX` are now +protocol errors. This is consistent with the RESP specification. On 32-bit +platforms, the upper bound is lowered to `SIZE_MAX`. + +Change `redisReply.len` to `size_t`, as it denotes the the size of a string + +User code should compare this to `size_t` values as well. If it was used to +compare to other values, casting might be necessary or can be removed, if +casting was applied before. + +## Upgrading from `<0.9.0` + +Version 0.9.0 is a major overhaul of hiredis in every aspect. However, upgrading existing +code using hiredis should not be a big pain. The key thing to keep in mind when +upgrading is that hiredis >= 0.9.0 uses a `redisContext*` to keep state, in contrast to +the stateless 0.0.1 that only has a file descriptor to work with. + +## Synchronous API + +To consume the synchronous API, there are only a few function calls that need to be introduced: + +```c +redisContext *redisConnect(const char *ip, int port); +void *redisCommand(redisContext *c, const char *format, ...); +void freeReplyObject(void *reply); +``` + +### Connecting + +The function `redisConnect` is used to create a so-called `redisContext`. The +context is where Hiredis holds state for a connection. The `redisContext` +struct has an integer `err` field that is non-zero when the connection is in +an error state. The field `errstr` will contain a string with a description of +the error. More information on errors can be found in the **Errors** section. +After trying to connect to Redis using `redisConnect` you should +check the `err` field to see if establishing the connection was successful: +```c +redisContext *c = redisConnect("127.0.0.1", 6379); +if (c == NULL || c->err) { + if (c) { + printf("Error: %s\n", c->errstr); + // handle error + } else { + printf("Can't allocate redis context\n"); + } +} +``` + +*Note: A `redisContext` is not thread-safe.* + +### Sending commands + +There are several ways to issue commands to Redis. The first that will be introduced is +`redisCommand`. This function takes a format similar to printf. In the simplest form, +it is used like this: +```c +reply = redisCommand(context, "SET foo bar"); +``` + +The specifier `%s` interpolates a string in the command, and uses `strlen` to +determine the length of the string: +```c +reply = redisCommand(context, "SET foo %s", value); +``` +When you need to pass binary safe strings in a command, the `%b` specifier can be +used. Together with a pointer to the string, it requires a `size_t` length argument +of the string: +```c +reply = redisCommand(context, "SET foo %b", value, (size_t) valuelen); +``` +Internally, Hiredis splits the command in different arguments and will +convert it to the protocol used to communicate with Redis. +One or more spaces separates arguments, so you can use the specifiers +anywhere in an argument: +```c +reply = redisCommand(context, "SET key:%s %s", myid, value); +``` + +### Using replies + +The return value of `redisCommand` holds a reply when the command was +successfully executed. When an error occurs, the return value is `NULL` and +the `err` field in the context will be set (see section on **Errors**). +Once an error is returned the context cannot be reused and you should set up +a new connection. + +The standard replies that `redisCommand` are of the type `redisReply`. The +`type` field in the `redisReply` should be used to test what kind of reply +was received: + +### RESP2 + +* **`REDIS_REPLY_STATUS`**: + * The command replied with a status reply. The status string can be accessed using `reply->str`. + The length of this string can be accessed using `reply->len`. + +* **`REDIS_REPLY_ERROR`**: + * The command replied with an error. The error string can be accessed identical to `REDIS_REPLY_STATUS`. + +* **`REDIS_REPLY_INTEGER`**: + * The command replied with an integer. The integer value can be accessed using the + `reply->integer` field of type `long long`. + +* **`REDIS_REPLY_NIL`**: + * The command replied with a **nil** object. There is no data to access. + +* **`REDIS_REPLY_STRING`**: + * A bulk (string) reply. The value of the reply can be accessed using `reply->str`. + The length of this string can be accessed using `reply->len`. + +* **`REDIS_REPLY_ARRAY`**: + * A multi bulk reply. The number of elements in the multi bulk reply is stored in + `reply->elements`. Every element in the multi bulk reply is a `redisReply` object as well + and can be accessed via `reply->element[..index..]`. + Redis may reply with nested arrays but this is fully supported. + +### RESP3 + +Hiredis also supports every new `RESP3` data type which are as follows. For more information about the protocol see the `RESP3` [specification.](https://github.com/antirez/RESP3/blob/master/spec.md) + +* **`REDIS_REPLY_DOUBLE`**: + * The command replied with a double-precision floating point number. + The value is stored as a string in the `str` member, and can be converted with `strtod` or similar. + +* **`REDIS_REPLY_BOOL`**: + * A boolean true/false reply. + The value is stored in the `integer` member and will be either `0` or `1`. + +* **`REDIS_REPLY_MAP`**: + * An array with the added invariant that there will always be an even number of elements. + The MAP is functionally equivelant to `REDIS_REPLY_ARRAY` except for the previously mentioned invariant. + +* **`REDIS_REPLY_SET`**: + * An array response where each entry is unique. + Like the MAP type, the data is identical to an array response except there are no duplicate values. + +* **`REDIS_REPLY_PUSH`**: + * An array that can be generated spontaneously by Redis. + This array response will always contain at least two subelements. The first contains the type of `PUSH` message (e.g. `message`, or `invalidate`), and the second being a sub-array with the `PUSH` payload itself. + +* **`REDIS_REPLY_ATTR`**: + * An array structurally identical to a `MAP` but intended as meta-data about a reply. + _As of Redis 6.0.6 this reply type is not used in Redis_ + +* **`REDIS_REPLY_BIGNUM`**: + * A string representing an arbitrarily large signed or unsigned integer value. + The number will be encoded as a string in the `str` member of `redisReply`. + +* **`REDIS_REPLY_VERB`**: + * A verbatim string, intended to be presented to the user without modification. + The string payload is stored in the `str` memeber, and type data is stored in the `vtype` member (e.g. `txt` for raw text or `md` for markdown). + +Replies should be freed using the `freeReplyObject()` function. +Note that this function will take care of freeing sub-reply objects +contained in arrays and nested arrays, so there is no need for the user to +free the sub replies (it is actually harmful and will corrupt the memory). + +**Important:** the current version of hiredis (1.0.0) frees replies when the +asynchronous API is used. This means you should not call `freeReplyObject` when +you use this API. The reply is cleaned up by hiredis _after_ the callback +returns. We may introduce a flag to make this configurable in future versions of the library. + +### Cleaning up + +To disconnect and free the context the following function can be used: +```c +void redisFree(redisContext *c); +``` +This function immediately closes the socket and then frees the allocations done in +creating the context. + +### Sending commands (cont'd) + +Together with `redisCommand`, the function `redisCommandArgv` can be used to issue commands. +It has the following prototype: +```c +void *redisCommandArgv(redisContext *c, int argc, const char **argv, const size_t *argvlen); +``` +It takes the number of arguments `argc`, an array of strings `argv` and the lengths of the +arguments `argvlen`. For convenience, `argvlen` may be set to `NULL` and the function will +use `strlen(3)` on every argument to determine its length. Obviously, when any of the arguments +need to be binary safe, the entire array of lengths `argvlen` should be provided. + +The return value has the same semantic as `redisCommand`. + +### Pipelining + +To explain how Hiredis supports pipelining in a blocking connection, there needs to be +understanding of the internal execution flow. + +When any of the functions in the `redisCommand` family is called, Hiredis first formats the +command according to the Redis protocol. The formatted command is then put in the output buffer +of the context. This output buffer is dynamic, so it can hold any number of commands. +After the command is put in the output buffer, `redisGetReply` is called. This function has the +following two execution paths: + +1. The input buffer is non-empty: + * Try to parse a single reply from the input buffer and return it + * If no reply could be parsed, continue at *2* +2. The input buffer is empty: + * Write the **entire** output buffer to the socket + * Read from the socket until a single reply could be parsed + +The function `redisGetReply` is exported as part of the Hiredis API and can be used when a reply +is expected on the socket. To pipeline commands, the only things that needs to be done is +filling up the output buffer. For this cause, two commands can be used that are identical +to the `redisCommand` family, apart from not returning a reply: +```c +void redisAppendCommand(redisContext *c, const char *format, ...); +void redisAppendCommandArgv(redisContext *c, int argc, const char **argv, const size_t *argvlen); +``` +After calling either function one or more times, `redisGetReply` can be used to receive the +subsequent replies. The return value for this function is either `REDIS_OK` or `REDIS_ERR`, where +the latter means an error occurred while reading a reply. Just as with the other commands, +the `err` field in the context can be used to find out what the cause of this error is. + +The following examples shows a simple pipeline (resulting in only a single call to `write(2)` and +a single call to `read(2)`): +```c +redisReply *reply; +redisAppendCommand(context,"SET foo bar"); +redisAppendCommand(context,"GET foo"); +redisGetReply(context,(void *)&reply); // reply for SET +freeReplyObject(reply); +redisGetReply(context,(void *)&reply); // reply for GET +freeReplyObject(reply); +``` +This API can also be used to implement a blocking subscriber: +```c +reply = redisCommand(context,"SUBSCRIBE foo"); +freeReplyObject(reply); +while(redisGetReply(context,(void *)&reply) == REDIS_OK) { + // consume message + freeReplyObject(reply); +} +``` +### Errors + +When a function call is not successful, depending on the function either `NULL` or `REDIS_ERR` is +returned. The `err` field inside the context will be non-zero and set to one of the +following constants: + +* **`REDIS_ERR_IO`**: + There was an I/O error while creating the connection, trying to write + to the socket or read from the socket. If you included `errno.h` in your + application, you can use the global `errno` variable to find out what is + wrong. + +* **`REDIS_ERR_EOF`**: + The server closed the connection which resulted in an empty read. + +* **`REDIS_ERR_PROTOCOL`**: + There was an error while parsing the protocol. + +* **`REDIS_ERR_OTHER`**: + Any other error. Currently, it is only used when a specified hostname to connect + to cannot be resolved. + +In every case, the `errstr` field in the context will be set to hold a string representation +of the error. + +## Asynchronous API + +Hiredis comes with an asynchronous API that works easily with any event library. +Examples are bundled that show using Hiredis with [libev](http://software.schmorp.de/pkg/libev.html) +and [libevent](http://monkey.org/~provos/libevent/). + +### Connecting + +The function `redisAsyncConnect` can be used to establish a non-blocking connection to +Redis. It returns a pointer to the newly created `redisAsyncContext` struct. The `err` field +should be checked after creation to see if there were errors creating the connection. +Because the connection that will be created is non-blocking, the kernel is not able to +instantly return if the specified host and port is able to accept a connection. + +*Note: A `redisAsyncContext` is not thread-safe.* + +```c +redisAsyncContext *c = redisAsyncConnect("127.0.0.1", 6379); +if (c->err) { + printf("Error: %s\n", c->errstr); + // handle error +} +``` + +The asynchronous context can hold a disconnect callback function that is called when the +connection is disconnected (either because of an error or per user request). This function should +have the following prototype: +```c +void(const redisAsyncContext *c, int status); +``` +On a disconnect, the `status` argument is set to `REDIS_OK` when disconnection was initiated by the +user, or `REDIS_ERR` when the disconnection was caused by an error. When it is `REDIS_ERR`, the `err` +field in the context can be accessed to find out the cause of the error. + +The context object is always freed after the disconnect callback fired. When a reconnect is needed, +the disconnect callback is a good point to do so. + +Setting the disconnect callback can only be done once per context. For subsequent calls it will +return `REDIS_ERR`. The function to set the disconnect callback has the following prototype: +```c +int redisAsyncSetDisconnectCallback(redisAsyncContext *ac, redisDisconnectCallback *fn); +``` +`ac->data` may be used to pass user data to this callback, the same can be done for redisConnectCallback. +### Sending commands and their callbacks + +In an asynchronous context, commands are automatically pipelined due to the nature of an event loop. +Therefore, unlike the synchronous API, there is only a single way to send commands. +Because commands are sent to Redis asynchronously, issuing a command requires a callback function +that is called when the reply is received. Reply callbacks should have the following prototype: +```c +void(redisAsyncContext *c, void *reply, void *privdata); +``` +The `privdata` argument can be used to curry arbitrary data to the callback from the point where +the command is initially queued for execution. + +The functions that can be used to issue commands in an asynchronous context are: +```c +int redisAsyncCommand( + redisAsyncContext *ac, redisCallbackFn *fn, void *privdata, + const char *format, ...); +int redisAsyncCommandArgv( + redisAsyncContext *ac, redisCallbackFn *fn, void *privdata, + int argc, const char **argv, const size_t *argvlen); +``` +Both functions work like their blocking counterparts. The return value is `REDIS_OK` when the command +was successfully added to the output buffer and `REDIS_ERR` otherwise. Example: when the connection +is being disconnected per user-request, no new commands may be added to the output buffer and `REDIS_ERR` is +returned on calls to the `redisAsyncCommand` family. + +If the reply for a command with a `NULL` callback is read, it is immediately freed. When the callback +for a command is non-`NULL`, the memory is freed immediately following the callback: the reply is only +valid for the duration of the callback. + +All pending callbacks are called with a `NULL` reply when the context encountered an error. + +### Disconnecting + +An asynchronous connection can be terminated using: +```c +void redisAsyncDisconnect(redisAsyncContext *ac); +``` +When this function is called, the connection is **not** immediately terminated. Instead, new +commands are no longer accepted and the connection is only terminated when all pending commands +have been written to the socket, their respective replies have been read and their respective +callbacks have been executed. After this, the disconnection callback is executed with the +`REDIS_OK` status and the context object is freed. + +### Hooking it up to event library *X* + +There are a few hooks that need to be set on the context object after it is created. +See the `adapters/` directory for bindings to *libev* and *libevent*. + +## Reply parsing API + +Hiredis comes with a reply parsing API that makes it easy for writing higher +level language bindings. + +The reply parsing API consists of the following functions: +```c +redisReader *redisReaderCreate(void); +void redisReaderFree(redisReader *reader); +int redisReaderFeed(redisReader *reader, const char *buf, size_t len); +int redisReaderGetReply(redisReader *reader, void **reply); +``` +The same set of functions are used internally by hiredis when creating a +normal Redis context, the above API just exposes it to the user for a direct +usage. + +### Usage + +The function `redisReaderCreate` creates a `redisReader` structure that holds a +buffer with unparsed data and state for the protocol parser. + +Incoming data -- most likely from a socket -- can be placed in the internal +buffer of the `redisReader` using `redisReaderFeed`. This function will make a +copy of the buffer pointed to by `buf` for `len` bytes. This data is parsed +when `redisReaderGetReply` is called. This function returns an integer status +and a reply object (as described above) via `void **reply`. The returned status +can be either `REDIS_OK` or `REDIS_ERR`, where the latter means something went +wrong (either a protocol error, or an out of memory error). + +The parser limits the level of nesting for multi bulk payloads to 7. If the +multi bulk nesting level is higher than this, the parser returns an error. + +### Customizing replies + +The function `redisReaderGetReply` creates `redisReply` and makes the function +argument `reply` point to the created `redisReply` variable. For instance, if +the response of type `REDIS_REPLY_STATUS` then the `str` field of `redisReply` +will hold the status as a vanilla C string. However, the functions that are +responsible for creating instances of the `redisReply` can be customized by +setting the `fn` field on the `redisReader` struct. This should be done +immediately after creating the `redisReader`. + +For example, [hiredis-rb](https://github.com/pietern/hiredis-rb/blob/master/ext/hiredis_ext/reader.c) +uses customized reply object functions to create Ruby objects. + +### Reader max buffer + +Both when using the Reader API directly or when using it indirectly via a +normal Redis context, the redisReader structure uses a buffer in order to +accumulate data from the server. +Usually this buffer is destroyed when it is empty and is larger than 16 +KiB in order to avoid wasting memory in unused buffers + +However when working with very big payloads destroying the buffer may slow +down performances considerably, so it is possible to modify the max size of +an idle buffer changing the value of the `maxbuf` field of the reader structure +to the desired value. The special value of 0 means that there is no maximum +value for an idle buffer, so the buffer will never get freed. + +For instance if you have a normal Redis context you can set the maximum idle +buffer to zero (unlimited) just with: +```c +context->reader->maxbuf = 0; +``` +This should be done only in order to maximize performances when working with +large payloads. The context should be set back to `REDIS_READER_MAX_BUF` again +as soon as possible in order to prevent allocation of useless memory. + +### Reader max array elements + +By default the hiredis reply parser sets the maximum number of multi-bulk elements +to 2^32 - 1 or 4,294,967,295 entries. If you need to process multi-bulk replies +with more than this many elements you can set the value higher or to zero, meaning +unlimited with: +```c +context->reader->maxelements = 0; +``` + +## SSL/TLS Support + +### Building + +SSL/TLS support is not built by default and requires an explicit flag: + + make USE_SSL=1 + +This requires OpenSSL development package (e.g. including header files to be +available. + +When enabled, SSL/TLS support is built into extra `libhiredis_ssl.a` and +`libhiredis_ssl.so` static/dynamic libraries. This leaves the original libraries +unaffected so no additional dependencies are introduced. + +### Using it + +First, you'll need to make sure you include the SSL header file: + +```c +#include "hiredis.h" +#include "hiredis_ssl.h" +``` + +You will also need to link against `libhiredis_ssl`, **in addition** to +`libhiredis` and add `-lssl -lcrypto` to satisfy its dependencies. + +Hiredis implements SSL/TLS on top of its normal `redisContext` or +`redisAsyncContext`, so you will need to establish a connection first and then +initiate an SSL/TLS handshake. + +#### Hiredis OpenSSL Wrappers + +Before Hiredis can negotiate an SSL/TLS connection, it is necessary to +initialize OpenSSL and create a context. You can do that in two ways: + +1. Work directly with the OpenSSL API to initialize the library's global context + and create `SSL_CTX *` and `SSL *` contexts. With an `SSL *` object you can + call `redisInitiateSSL()`. +2. Work with a set of Hiredis-provided wrappers around OpenSSL, create a + `redisSSLContext` object to hold configuration and use + `redisInitiateSSLWithContext()` to initiate the SSL/TLS handshake. + +```c +/* An Hiredis SSL context. It holds SSL configuration and can be reused across + * many contexts. + */ +redisSSLContext *ssl; + +/* An error variable to indicate what went wrong, if the context fails to + * initialize. + */ +redisSSLContextError ssl_error; + +/* Initialize global OpenSSL state. + * + * You should call this only once when your app initializes, and only if + * you don't explicitly or implicitly initialize OpenSSL it elsewhere. + */ +redisInitOpenSSL(); + +/* Create SSL context */ +ssl = redisCreateSSLContext( + "cacertbundle.crt", /* File name of trusted CA/ca bundle file, optional */ + "/path/to/certs", /* Path of trusted certificates, optional */ + "client_cert.pem", /* File name of client certificate file, optional */ + "client_key.pem", /* File name of client private key, optional */ + "redis.mydomain.com", /* Server name to request (SNI), optional */ + &ssl_error + ) != REDIS_OK) { + printf("SSL error: %s\n", redisSSLContextGetError(ssl_error); + /* Abort... */ + } + +/* Create Redis context and establish connection */ +c = redisConnect("localhost", 6443); +if (c == NULL || c->err) { + /* Handle error and abort... */ +} + +/* Negotiate SSL/TLS */ +if (redisInitiateSSLWithContext(c, ssl) != REDIS_OK) { + /* Handle error, in c->err / c->errstr */ +} +``` + +## RESP3 PUSH replies +Redis 6.0 introduced PUSH replies with the reply-type `>`. These messages are generated spontaneously and can arrive at any time, so must be handled using callbacks. + +### Default behavior +Hiredis installs handlers on `redisContext` and `redisAsyncContext` by default, which will intercept and free any PUSH replies detected. This means existing code will work as-is after upgrading to Redis 6 and switching to `RESP3`. + +### Custom PUSH handler prototypes +The callback prototypes differ between `redisContext` and `redisAsyncContext`. + +#### redisContext +```c +void my_push_handler(void *privdata, void *reply) { + /* Handle the reply */ + + /* Note: We need to free the reply in our custom handler for + blocking contexts. This lets us keep the reply if + we want. */ + freeReplyObject(reply); +} +``` + +#### redisAsyncContext +```c +void my_async_push_handler(redisAsyncContext *ac, void *reply) { + /* Handle the reply */ + + /* Note: Because async hiredis always frees replies, you should + not call freeReplyObject in an async push callback. */ +} +``` + +### Installing a custom handler +There are two ways to set your own PUSH handlers. + +1. Set `push_cb` or `async_push_cb` in the `redisOptions` struct and connect with `redisConnectWithOptions` or `redisAsyncConnectWithOptions`. + ```c + redisOptions = {0}; + REDIS_OPTIONS_SET_TCP(&options, "127.0.0.1", 6379); + options->push_cb = my_push_handler; + redisContext *context = redisConnectWithOptions(&options); + ``` +2. Call `redisSetPushCallback` or `redisAsyncSetPushCallback` on a connected context. + ```c + redisContext *context = redisConnect("127.0.0.1", 6379); + redisSetPushCallback(context, my_push_handler); + ``` + + _Note `redisSetPushCallback` and `redisAsyncSetPushCallback` both return any currently configured handler, making it easy to override and then return to the old value._ + +### Specifying no handler +If you have a unique use-case where you don't want hiredis to automatically intercept and free PUSH replies, you will want to configure no handler at all. This can be done in two ways. +1. Set the `REDIS_OPT_NO_PUSH_AUTOFREE` flag in `redisOptions` and leave the callback function pointer `NULL`. + ```c + redisOptions = {0}; + REDIS_OPTIONS_SET_TCP(&options, "127.0.0.1", 6379); + options->options |= REDIS_OPT_NO_PUSH_AUTOFREE; + redisContext *context = redisConnectWithOptions(&options); + ``` +3.

immutable, so all iterators on results and rows are actually +`const_iterator`s. There are also `const_reverse_iterator` types, which +iterate backwards from `rbegin()` to `rend()` exclusive. + +All these iterator types provide one extra bit of convenience that you won't +normally find in C++ iterators: referential transparency. You don't need to +dereference them to get to the row or field they refer to. That is, instead +of `row->end()` you can also choose to say `row.end()`. Similarly, you +may prefer `field.c_str()` over `field->c_str()`. + +This becomes really helpful with the array-indexing operator. With regular +C++ iterators you would need ugly expressions like `(*row)[0]` or +`row->operator[](0)`. With the iterator types defined by the result and +row classes you can simply say `row[0]`. + + +Streaming rows +-------------- + +There's another way to go through the rows coming out of a query. It's +usually easier and faster, but there are drawbacks. + +**One,** you start getting rows before all the data has come in from the +database. That speeds things up, but what happens if you lose your network +connection while transferring the data? Your application may already have +processed some of the data before finding out that the rest isn't coming. If +that is a problem for your application, streaming may not be the right choice. + +**Two,** streaming only works for some types of query. The `stream()` function +wraps your query in a PostgreSQL `COPY` command, and `COPY` only supports a few +commands: `SELECT`, `VALUES`, `or an `INSERT`, `UPDATE`, or `DELETE` with a +`RETURNING` clause. See the `COPY` documentation here: +https://www.postgresql.org/docs/current/sql-copy.html + +**Three,** when you convert a field to a "view" type (such as +`std::string_view` or `std::basic_string_view`), the view points to +underlying data which only stays valid until you iterate to the next row or +exit the loop. So if you want to use that data for longer than a single +iteration of the streaming loop, you'll have to store it somewhere yourself. + +Now for the good news. Streaming does make it very easy to query data and loop +over it: + +```cxx + for (auto [id, name, x, y] : + tx.stream( + "SELECT id, name, x, y FROM point")) + process(id + 1, "point-" + name, x * 10.0, y * 10.0); +``` + +The conversion to C++ types (here `int`, `std::string_view`, and two `float`s) +is built into the function. You never even see `row` objects, `field` objects, +iterators, or conversion methods. You just put in your query and you receive +your data. diff --git a/ext/libpqxx-7.7.3/install/ubuntu22.04/share/doc/libpqxx/binary-data.md b/ext/libpqxx-7.7.3/install/ubuntu22.04/share/doc/libpqxx/binary-data.md new file mode 100644 index 000000000..20da8dc0c --- /dev/null +++ b/ext/libpqxx-7.7.3/install/ubuntu22.04/share/doc/libpqxx/binary-data.md @@ -0,0 +1,56 @@ +Binary data {#binary} +=========== + +The database has two ways of storing binary data: `BYTEA` is like a string, but +containing bytes rather than text characters. And _large objects_ are more +like a separate table containing binary objects. + +Generally you'll want to use `BYTEA` for reasonably-sized values, and large +objects for very large values. + +That's the database side. On the C++ side, in libpqxx, all binary data must be +either `std::basic_string` or `std::basic_string_view`; +or if you're building in C++20 or better, anything that's a block of +contiguous `std::byte` in memory. + +So for example, if you want to write a large object, you'd create a +`pqxx::blob` object. And you might use that to write data in the form of +`std::basic_string_view`. + +Your particular binary data may look different though. You may have it in a +`std::string`, or a `std::vector`, or a pointer to `char` +accompanied by a size (which could be signed or unsigned, and of any of a few +different widths). Sometimes that's your choice, or sometimes some other +library will dictate what form it takes. + +So long as it's _basically_ still a block of bytes though, you can use +`pqxx::binary_cast` to construct a `std::basic_string_view` from it. + +There are two forms of `binary_cast`. One takes a single argument that must +support `std::data()` and `std::size()`: + + std::string hi{"Hello binary world"}; + my_blob.write(pqxx::binary_cast(hi); + +The other takes a pointer and a size: + + char const greeting[] = "Hello binary world"; + char const *hi = greeting; + my_blob.write(pqxx::binary_cast(hi, sizeof(greeting))); + + +Caveats +------- + +There are some restrictions on `binary_cast` that you must be aware of. + +First, your data must of a type that gives us _bytes._ So: `char`, +`unsigned char`, `signed char`, `int8_t`, `uint8_t`, or of course `std::byte`. +You can't feed in a vector of `double`, or anything like that. + +Second, the data must be laid out as a contiguous block in memory. If there's +no `std::data()` implementation for your type, it's not suitable. + +Third, `binary_cast` only constructs something like a `std::string_view`.

When you +include an integer value in a query, you use `to_string` to convert it to that +text format. When you get a query result field "as a float," it converts from +the text format to a floating-point type. These conversions are everywhere in +libpqxx. + +The conversion sydstem supports many built-in types, but it is also extensible. +You can "teach" libpqxx (in the scope of your own application) to convert +additional types of values to and from PostgreSQL's string format. + +This is massively useful, but it's not for the faint of heart. You'll need to +specialise some templates. And, **the API for doing this can change with any +major libpqxx release.** + + +Converting types +---------------- + +In your application, a conversion is driven entirely by a C++ type you specify. +The value's SQL type has nothing to do with it, nor is there anything in the +string that would identify its type. + +So, if you've SELECTed a 64-bit integer from the database, and you try to +convert it to a C++ "short," one of two things will happen: either the number +is small enough to fit in your `short` (and it just works), or else it throws a +conversion exception. + +Or, your database table might have a text column, but a given field may contain +a string that _looks_ just like a number. You can convert that value to an +integer type just fine. Or to a floating-point type. All that matters to the +conversion is the actual value, and the type. + +In some cases the templates for these conversions can tell the type from the +arguments you pass them: + + auto x = to_string(99); + +In other cases you may need to instantiate template explicitly: + + auto y = from_string("99"); + + +Supporting a new type +--------------------- + +Let's say you have some other SQL type which you want to be able to store in, +or retrieve from, the database. What would it take to support that? + +Sometimes you do not need _complete_ support. You might need a conversion _to_ +a string but not _from_ a string, for example. The conversion is defined at +compile time, so don't be too afraid to be incomplete. If you leave out one of +these steps, it's not going to crash at run time or mess up your data. The +worst that can happen is that your code won't build. + +So what do you need for a complete conversion? + +First off, of course, you need a C++ type. It may be your own, but it +doesn't have to be. It could be a type from a third-party library, or even one +from the standard library that libpqxx does not yet support. + +You also specialise the `pqxx::type_name` variable to specify the type's name. +This is important for all code which mentions your type in human-readable text, +such as error messages. + +Then, does your type have a built-in null value? You specialise the +`pqxx::nullness` template to specify the details. + +Finally, you specialise the `pqxx::string_traits` template. This is where you +define the actual conversions. + +Let's go through these steps one by one. + + +Your type +--------- + +You'll need a type for which the conversions are not yet defined, because the +C++ type is what determines the right conversion. One type, one set of +conversions. + +The type doesn't have to be one that you create. The conversion logic was +designed such that you can build it around any type. So you can just as +easily build a conversion for a type that's defined somewhere else. There's +no need to include any special methods or other members inside it. That's also +how libpqxx can support converting built-in types like `int`. + +By the way, if the type is an enum, you don't need to do any of this. Just +invoke the preprocessor macro `PQXX_DECLARE_ENUM_CONVERSION`, from the global +namespace near the top of your translation unit, and pass the type as an +argument. + +The library also provides specialisations for `std::optional`, +`std::shared_ptr`, and `std::unique_ptr`. If you have conversions for +`T`, you'll also have conversions for those. + + +Specialise `type_name` +---------------------- + +When errors happen during conversion, libpqxx will compose error messages for +the user. Sometimes these will include the name of the type that's being +converted. + +To tell libpqxx the name of each type, there's a template variable called +`pqxx::type_name`. For any given type `T`, it should have a specialisation +that provides that `T`'s human-readable name: + + namespace pqxx + { + template<> std::string const type_name{"T"}; + } + +(Yes, this means that you need to define something inside the pqxx namespace. +Future versions of libpqxx may move this into a separate namespace.) + +Define this early on in your translation unit, before any code that might cause +libpqxx to need the name. That way, the libpqxx code which needs to know the +type's name can see your definition. + + +Specialise `nullness` +--------------------- + +A struct template `pqxx::nullness` defines whether your type has a natural +"null value" built in. If so, it also provides member functions for producing +and recognising null values. + +The simplest scenario is also the most common: most types don't have a null +value built in. In that case, derive your nullness traits from +`pqxx::no_null`: + + namespace pqxx + { + template<> struct nullness : pqxx::no_null {}; + } + +(Here again you're defining this in the pqxx namespace.) + +If your type does have a natural null value, the definition gets a little more +complex: + + namespace pqxx + { + template<> struct nullness + { + static constexpr bool has_null{true}; + static constexpr bool always_null{false}; + + static bool is_null(T const &value) + { + // Return whether "value" is null. + return ...; + } + + [[nodiscard]] static T null() + { + // Return a null value. + return ...; + } + }; + } + +You may be wondering why there's a function to produce a null value, but also a +function to check whether a value is null. Why not just compare the value to +the result of `null()`? Because two null values may not be equal. `T` may +have several different null values. Or it may override the comparison +operator, similar to SQL where NULL is not equal to NULL. + +As a third case, your type may be one that _always_ represents a null value. +This is the case for `std::nullptr_t` and `std::nullopt_t`. In that case, you +set `nullness::always_null` to `true` (as well as `has_null` of course), +and you won't need to define any actual conversions. + + +Specialise `string_traits` +------------------------- + +This part is more work. (You can skip it for types that are _always_ null, +but those will be rare.) Specialise the `pqxx::string_traits` template: + + namespace pqxx + { + template<> struct string_traits + { + static T from_string(std::string_view text); + static zview to_buf(char *begin, char *end, T const &value); + static char *into_buf(char *begin, char *end, T const &value); + static std::size_t size_buffer(T const &value) noexcept; + }; + } + +You'll also need to write those member functions, or as many of them as needed +to get your code to build. + + +### `from_string` + +We start off simple: `from_string` parses a string as a value of `T`, and +returns that value. + +The string may not be zero-terminated; it's just the `string_view` from +beginning to end (exclusive). In your tests, cover cases where the string +does not end in a zero byte. + +It's perfectly possible that the string isn't actually a `T` value. Mistakes +happen. In that case, throw a `pqxx::conversion_error`. + +(Of course it's also possible that you run into some other error, so it's fine +to throw different exceptions as well. But when it's definitely "this is not +the right format for a `T`," throw `conversion_error`.) + + +### `to_buf` + +In this function, you convert a value of `T` into a string that the postgres +server will understand. + +The caller will provide you with a buffer where you can write the string, if +you need it: from `begin` to `end` exclusive. It's a half-open interval, so +don't access `*end`. + +If the buffer is insufficient for you to do the conversion, throw a +`pqxx::conversion_overrun`. It doesn't have to be exact: you can be a little +pessimistic and demand a bit more space than you need. Just be sure to throw +the exception if there's any risk of overrunning the buffer. + +You don't _have_ to use the buffer for this function though. For example, +`pqxx::string_traits::to_buf` returns a compile-time constant string and +ignores the buffer. + +Even if you do use the buffer, your string does not _have_ to start at the +beginning of the buffer. For example, the integer conversions start by writing +the _least_ significant digit to the _end_ of the buffer, and then writes the +more significant digits before it. It was just more convenient. + +Return a `pqxx::zview`. This is basically a `std::string_view`, but with one +difference: a `zview` guarantees that there will be a valid zero byte right +after the `string_view`. The zero byte is not counted as part of its size, but +it will be there. + +Expressed in code, this rule must hold: + + void invariant(zview z) + { + assert(z[std::size(z)] == 0); + } + +Make sure you write your trailing zero _before_ the `end`. If the trailing +zero doesn't fit in the buffer, then there's just not enough room to perform +the conversion. + +Beware of locales when converting. If you use standard library features like +`sprintf`, they may obey whatever locale is currently set on the system. That +means that a simple integer like 1000000 may come out as "1000000" on your +system, but as "1,000,000" on mine, or as "1.000.000" for somebody else, and on +an Indian system it may be "1,00,000". Values coming from or going to the +database should be in non-localised formats. You can use libpqxx functions for +those conversions: `pqxx::from_string`, `pqxx::to_string`, `pqxx::to_buf`. + + +### `into_buf` + +This is a stricter version of `to_buf`. All the same requirements apply, but +in addition you must write your string into the buffer provided, starting +_exactly_ at `begin`. + +That's why this function returns just a simple pointer: the address right +behind the trailing zero. If the caller wants to use the string, they can +find it at `begin`. If they want to write a different value into the rest of +the buffer, they can start at the location you returned. + + +### `size_buffer` + +Here you estimate how much buffer space you need for converting a `T` to a +string. Be precise if you can, but pessimistic if you must. It's usually +better to waste a few unnecessary bytes than to spend a lot of time computing +the exact buffer space you need. And failing the conversion because you +under-budgeted the buffer is worst of all. + +Include the trailing zero in the buffer size. If your `to_buf` takes more +space than just what's needed to store the result, include that too. + +Make `size_buffer` a `constexpr` function if you can. It can allow the caller +to allocate the buffer on the stack, with a size known at compile time. + + +Optional: Specialise `is_unquoted_safe` +--------------------------------------- + +When converting arrays or composite values to strings, libpqxx may need to +quote values and escape any special characters. This takes time. + +Some types though, such as integral or floating-point types, can never have +any special characters such as quotes, commas, or backslashes in their string +representations. In such cases, there's no need to quote or escape such values +in arrays or composite types. + +If your type is like that, you can tell libpqxx about this by defining: + + namespace pqxx + { + template<> inline constexpr bool is_unquoted_safe{true}; + } + +The code that converts this type of field to strings in an array or a composite +type can then use a simpler, more efficient variant of the code. It's always +safe to leave this out; it's _just_ an optimisation for when you're completely +sure that it's safe. + +Do not do this if a string representation of your type may contain a comma; +semicolon; parenthesis; brace; quote; backslash; newline; or any other +character that might need escaping. + + +Optional: Specialise `param_format` +----------------------------------- + +This one you don't generally need to worry about. Read on if you're writing a +type which represents raw binary data, or if you're writing a template where +_some specialisations_ may contain raw binary data. + +When you call parameterised statements, or prepared statements with parameters, +libpqxx needs to your parameters on to libpq, the underlying C-level PostgreSQL +client library. + +There are two formats for doing that: _text_ and _binary._ In the first, we +represent all values as strings, and the server then converts them into its own +internal binary representation. That's what the string conversions are all +about, and it's what we do for almost all types of parameters. + +But we do it differently when the parameter is a contiguous series of raw bytes +and the corresponding SQL type is `BYTEA`. There is a text format for those, +but we bypass it for efficiency. The server can use the binary data in the +exact same form, without any conversion or extra processing. The binary data +is also twice as compact during transport. + +(People sometimes ask why we can't just treat all types as binary. However the +general case isn't so clear-cut. The binary formats are not documented, there +are no guarantees that they will be platform-independent or that they will +remain stable, and there's no really solid way to detect when we might get the +format wrong. But also, the conversions aren't necessarily as straightforward +and efficient as they sound. So, for the general case, libpqxx sticks with the +text formats. Raw binary data alone stands out as a clear win.) + +Long story short, the machinery for passing parameters needs to know: is this +parameter a binary string, or not? In the normal case it can assume "no," and +that's what it does. The text format is always a safe choice; we just try to +use the binary format where it's faster. + +The `param_format` function template is what makes the decision. We specialise +it for types which may be binary strings, and use the default for all other +types. + +"Types which _may_ be binary"? You might think we know whether a type is a +binary type or not. But there are some complications with generic types. + +Templates like `std::shared_ptr`, `std::optional`, and so on act like +"wrappers" for another type. A `std::optional` is binary if `T` is binary. +Otherwise, it's not. If you're building support for a template of this nature, +you'll probably want to implement `param_format` for it. + +The decision to use binary format is made based on a given object, not +necessarily based on the type in general. Look at `std::variant`. If you have +a `std::variant` type which can hold an `int` or a binary string, is that a +binary parameter? We can't decide without knowing the individual object. + +Containers are another hard case. Should we pass `std::vector` in binary? +Even when `T` is a binary type, we don't currently have any way to pass an +array in binary format, so we always pass it as text. diff --git a/ext/libpqxx-7.7.3/install/ubuntu22.04/share/doc/libpqxx/escaping.md b/ext/libpqxx-7.7.3/install/ubuntu22.04/share/doc/libpqxx/escaping.md new file mode 100644 index 000000000..2ad9fe3db --- /dev/null +++ b/ext/libpqxx-7.7.3/install/ubuntu22.04/share/doc/libpqxx/escaping.md @@ -0,0 +1,74 @@ +String escaping {#escaping} +=============== + +Writing queries as strings is easy.

They're less flexible than SQL queries, and there's the risk of +losing your connection while you're in mid-stream, but you get some speed and +memory efficiencies in return. + +Both stream classes do data conversion for you: `stream_from` receives values +from the database in PostgreSQL's text format, and converts them to the C++ +types you specify. Likewise, `stream_to` converts C++ values you provide to +PostgreSQL's text format for transfer. (On its end, the database of course +converts values to and from their SQL types.) + + +Null values +----------- + +So how do you deal with nulls? It depends on the C++ type you're using. Some +types may have a built-in null value. For instance, if you have a +`char const *` value and you convert it to an SQL string, then converting a +`nullptr` will produce a NULL SQL value. + +But what do you do about C++ types which don't have a built-in null value, such +as `int`? The trick is to wrap it in `std::optional`. The difference between +`int` and `std::optional` is that the former always has an `int` value, +and the latter doesn't have to. + +Actually it's not just `std::optional`. You can do the same thing with +`std::unique_ptr` or `std::shared_ptr`. A smart pointer is less efficient than +`std::optional` in most situations because they allocate their value on the +heap, but sometimes that's what you want in order to save moving or copying +large values around. + +This part is not generic though. It won't work with just any smart-pointer +type, just the ones which are explicitly supported: `shared_ptr` and +`unique_ptr`. If you really need to, you can build support for additional +wrappers and smart pointers by copying the implementation patterns from the +existing smart-pointer support. + + +stream\_from +------------ + +Use `stream_from` to read data directly from the database. It's faster than +the transaction's `exec` functions if the result contains enough rows. But +also, you won't need to keep your full result set in memory. That can really +matter with larger data sets. + +And, you can start processing your data right after the first row of data comes +in from the server. With `exec()` you need to wait to receive all data, and +then you begin processing. With `stream_from` you can be processing data on +the client side while the server is still sending you the rest. + +You don't actually need to create a `stream_from` object yourself, though you +can. Two shorthand functions, @ref pqxx::transaction_base::stream +and @ref pqxx::transaction_base::for_each, can create the streams for you with +a minimum of overhead. + +Not all kinds of queries will work in a stream. Internally the streams make +use of PostgreSQL's `COPY` command, so see the PostgreSQL documentation for +`COPY` for the exact limitations. Basic `SELECT` and `UPDATE ... RETURNING` +queries should just work. + +As you read a row, the stream converts its fields to a tuple type containing +the value types you ask for: + + auto stream pqxx::stream_from::query( + tx, "SELECT name, points FROM score"); + std::tuple row; + while (stream >> row) + process(row); + stream.complete(); + +As the stream reads each row, it converts that row's data into your tuple, +goes through your loop body, and then promptly forgets that row's data. This +means you can easily process more data than will fit in memory. + + +stream\_to +---------- + +Use `stream_to` to write data directly to a database table. This saves you +having to perform an `INSERT` for every row, and so it can be significantly +faster if you want to insert more than just one or two rows at a time. + +As with `stream_from`, you can specify the table and the columns, and not much +else. You insert tuple-like objects of your choice: + + pqxx::stream_to stream{ + tx, + "score", + std::vector{"name", "points"}}; + for (auto const &entry: scores) + stream << entry; + stream.complete(); + +Each row is processed as you provide it, and not retained in memory after that. + +The call to `complete()` is more important here than it is for `stream_from`. +It's a lot like a "commit" or "abort" at the end of a transaction. If you omit +it, it will be done automatically during the stream's destructor. But since +destructors can't throw exceptions, any failures at that stage won't be visible +in your code.

So if the documentation is unclear, please feel free to open an issue or pull request.

The dev branch is unstable. If you want to contribute, please create pull request on dev branch. + +## Installation + +### Install hiredis + +Since *redis-plus-plus* is based on *hiredis*, you should install *hiredis* first. The minimum version requirement for *hiredis* is **v0.12.1**. However, [the latest stable release](https://github.com/redis/hiredis/releases) of *hiredis* is always recommended. + +**NOTE**: You must ensure that there's only 1 version of hiredis is installed. Otherwise, you might get some wired problems. Check the following issues for example: [issue 135](https://github.com/sewenew/redis-plus-plus/issues/135), [issue 140](https://github.com/sewenew/redis-plus-plus/issues/140) and [issue 158](https://github.com/sewenew/redis-plus-plus/issues/158). + +Normally, you can install *hiredis* with a C++ package manager, and that's the easiest way to do it, e.g. `sudo apt-get install libhiredis-dev`. However, if you want to install the latest code of hiredis, or a specified version (e.g. async support needs hiredis v1.0.0 or later), you can install it from source. + +Note again: DO NOT INSTALL MULTIPLE VERSIONS OF HIREDIS. + +``` +git clone https://github.com/redis/hiredis.git + +cd hiredis + +make + +make install +``` + +By default, *hiredis* is installed at */usr/local*. If you want to install *hiredis* at non-default location, use the following commands to specify the installation path. + +``` +make PREFIX=/non/default/path + +make PREFIX=/non/default/path install +``` + +### Install redis-plus-plus + +*redis-plus-plus* is built with [CMAKE](https://cmake.org). + +``` +git clone https://github.com/sewenew/redis-plus-plus.git + +cd redis-plus-plus + +mkdir build + +cd build + +cmake -DREDIS_PLUS_PLUS_CXX_STANDARD=17 .. + +make + +make install + +cd .. +``` + +If *hiredis* is installed at non-default location, you should use `CMAKE_PREFIX_PATH` to specify the installation path of *hiredis*. By default, *redis-plus-plus* is installed at */usr/local*. However, you can use `CMAKE_INSTALL_PREFIX` to install *redis-plus-plus* at non-default location. + +``` +cmake -DCMAKE_PREFIX_PATH=/path/to/hiredis -DCMAKE_INSTALL_PREFIX=/path/to/install/redis-plus-plus .. +``` + +Since version 1.3.0, by default, *redis-plus-plus* is built with the `-std=c++17` standard. So that we can use the [std::string_view](#stringview) and [std::optional](#optional) features. However, it can also be built with the `-std=c++11` or `-std=c++14` standard, and in that case, we have our own simple implementation of `std::string_view` and `std::optional`. In order to explicitly specify c++ standard, you can use the following cmake flag: `-DREDIS_PLUS_PLUS_CXX_STANDARD=11`. + +``` +cmake -DCMAKE_PREFIX_PATH=/path/to/hiredis -DCMAKE_INSTALL_PREFIX=/path/to/install/redis-plus-plus -DREDIS_PLUS_PLUS_CXX_STANDARD=11 .. +``` + +**NOTE**: You should build *redis-plus-plus* and your application with the same standard, e.g. if you build *redis-plus-plus* with C++17 standard, you MUST also build your application code with C++17 standard. + +When compiling *redis-plus-plus*, it also compiles a test program, which might take a while. However, you can disable building test with the following cmake option: `-DREDIS_PLUS_PLUS_BUILD_TEST=OFF`. + +``` +cmake -DCMAKE_PREFIX_PATH=/path/to/hiredis -DCMAKE_INSTALL_PREFIX=/path/to/install/redis-plus-plus -DREDIS_PLUS_PLUS_BUILD_TEST=OFF .. +``` + +By default, *redis-plus-plus* builds both a static library and a shared library. If you only want to build one of them, you can disable the other with `-DREDIS_PLUS_PLUS_BUILD_STATIC=OFF` or `-DREDIS_PLUS_PLUS_BUILD_SHARED=OFF`. + +*redis-plus-plus* builds static library with `-fPIC` option, i.e. Position Independent Code, by default. However, you can disable it with `-DREDIS_PLUS_PLUS_BUILD_STATIC_WITH_PIC=OFF`. + +#### Windows Support + +Now *hiredis* has Windows support, and since Visual Studio 2017, Visual Studio has built-in support for CMake. So *redis-plus-plus* also supports Windows platform now. It has been fully tested with Visual Studio 2017 and later on Win 10. I'm not familiar with Visual Studio environment, and the following doc might not be accurate. If you're familiar with the Windows platform, feel free to update this doc on how to install *redis-plus-plus* on Windows. + +##### CMake Support On Visual Studio + +The following are some links on how to build CMake project with Visual Studio 2017 or later. If you're not familiar with it, you'd better read these instructions first: + +- [CMake support in Visual Studio](https://devblogs.microsoft.com/cppblog/cmake-support-in-visual-studio/) +- [CMake projects in Visual Studio](https://docs.microsoft.com/en-us/cpp/build/cmake-projects-in-visual-studio?view=vs-2017) +- [CMakeSettings.json schema reference](https://docs.microsoft.com/en-us/cpp/build/cmakesettings-reference?view=vs-2017) +- [Open a project from a GitHub repo](https://docs.microsoft.com/en-us/visualstudio/get-started/tutorial-open-project-from-repo?view=vs-2019#open-a-project-from-a-github-repo) + +**NOTE**: IMHO, Visual Studio 2017's support for CMake project is not very mature, and I recommend you to build *hiredis* and *redis-plus-plus with Visual Studio 2019. + +##### Build hiredis + +First of all, you need to get the latest code of *hiredis* on master branch. Older version might not support Windows platform. *hiredis*' CMakeLists.txt uses `add_compile_definitions` method, which is only supported by cmake 3.12 or later. However, Visual Studio 2017's cmake version is older than that. So if you're using Visual Studio 2017, you need to comment the following line in the CMakeLists.txt file: + +``` +#IF(WIN32) +# ADD_COMPILE_DEFINITIONS(_CRT_SECURE_NO_WARNINGS WIN32_LEAN_AND_MEAN) +#ENDIF() +``` + +You can use the **Open Folder** feature to open *hiredis* project, and build it with the instructions (links) mentioned above. + +##### Build redis-plus-plus + +Since *redis-plus-plus* depends on *hiredis*, we need to specify the installation paths of *hiredis* before building it. You can use the **Open Folder** feature to open *redis-plus-plus* project. You need to edit the *CMakeSetting.json* file (automatically generated by Visual Studio) to set *HIREDIS_HEADER*, *HIREDIS_LIB* and *TEST_HIREDIS_LIB* variables to specify the installation path of hiredis headers, installation path of hiredis dynamic library and installation path of hiredis static library. The following is an example of *CMakeSetting.json* file: + +``` +{ + "configurations": [ + { + "name": "x64-Release", + "generator": "Visual Studio 15 2017 Win64", + "configurationType": "Release", + "buildRoot": "${env.LOCALAPPDATA}\\CMakeBuild\\${workspaceHash}\\build\\${name}", + "cmakeCommandArgs": "", + "buildCommandArgs": "-m -v:minimal", + "variables": [ + { + "name": "HIREDIS_HEADER", + "value": "installation path of hiredis header files", + "type": "PATH" + }, + { + "name": "HIREDIS_LIB", + "value": "installation path of dynamic library of hiredis", + "type": "FILEPATH" + }, + { + "name": "TEST_HIREDIS_LIB", + "value": "installation path of static library of hiredis", + "type": "FILEPATH" + } + ] + } + ] +} +``` + +Then you can build it the instructions (links) mentioned above. If you're building with Visual Studio 2017 in debug mode, you might get [/bigobj error](https://docs.microsoft.com/en-us/cpp/build/reference/bigobj-increase-number-of-sections-in-dot-obj-file?view=vs-2017) when building the test. In this case, you can disable building test by setting `-DREDIS_PLUS_PLUS_BUILD_TEST=OFF` or build it in Release mode. + +**NOTE**: + +- Since 1.3.0, *redis-puls-plus* is built with C++17 by default, and you should also set your application code to be built with C++17. If you still want to build the *redis-plus-plus* with C++11, you can set the `REDIS_PLUS_PLUS_CXX_STANDARD` cmake option to 11. +- TLS/SSL support has not been tested on Windows yet. + +##### The Order of Header Files + +On Windows platform, if your application code also needs to include *windows.h*. You must ensure that *sw/redis++/redis++.h* is included before *windows.h*. Check [this issue](https://github.com/sewenew/redis-plus-plus/issues/194) for detail. + +#### Building a redis-plus-plus Debian Package (Optional) + +Basic support for building a GNU/Debian package is supplied with the use of cmake. +The following example shows how to build the Debian package: + +``` +mkdir build; cd build +cmake .. +cpack -G DEB +``` + +The install prefix may be modified as follows: + +``` +mkdir build; cd build +cmake -DCMAKE_INSTALL_PREFIX=/usr .. +cpack -G DEB +``` + +### Run Tests (Optional) + +*redis-plus-plus* has been fully tested with the following compilers: + +``` +gcc version 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) +gcc version 5.5.0 20171010 (Ubuntu 5.5.0-12ubuntu1) +gcc version 6.5.0 20181026 (Ubuntu 6.5.0-2ubuntu1~18.04) +gcc version 7.4.0 (Ubuntu 7.4.0-1ubuntu1~18.04.1) +gcc version 8.3.0 (Ubuntu 8.3.0-6ubuntu1~18.04.1) +gcc version 9.2.1 20191008 (Ubuntu 9.2.1-9ubuntu2) +gcc version 10.2.1 20210110 (Debian 10.2.1-6) +clang version 3.9.1-19ubuntu1 (tags/RELEASE_391/rc2) +clang version 4.0.1-10 (tags/RELEASE_401/final) +clang version 5.0.1-4 (tags/RELEASE_501/final) +clang version 6.0.0-1ubuntu2 (tags/RELEASE_600/final) +clang version 7.0.0-3~ubuntu0.18.04.1 (tags/RELEASE_700/final) +clang version 8.0.1-3build1 (tags/RELEASE_801/final) +Apple clang version 11.0.0 (clang-1100.0.33.12) +Visual Studio 2017 (Win 10) +Visual Studio 2019 (Win 10) +``` + +If you build *redis-plus-plus* with `-DREDIS_PLUS_PLUS_BUILD_TEST=ON` (the default behavior, and you can disable building test with `-DREDIS_PLUS_PLUS_BUILD_TEST=OFF`), you'll get a test program in *compile/test* directory: *compile/test/test_redis++*. + +In order to run the tests, you need to set up a Redis instance, and a Redis Cluster. Since the test program will send most of Redis commands to the server and cluster, you need to set up Redis of the latest version (by now, it's 5.0). Otherwise, the tests might fail. For example, if you set up Redis 4.0 for testing, the test program will fail when it tries to send the `ZPOPMAX` command (a Redis 5.0 command) to the server. If you want to run the tests with other Redis versions, you have to comment out commands that haven't been supported by your Redis, from test source files in *redis-plus-plus/test/src/sw/redis++/* directory. Sorry for the inconvenience, and I'll fix this problem to make the test program work with any version of Redis in the future. + +**NOTE**: The latest version of Redis is only a requirement for running the tests. In fact, you can use *redis-plus-plus* with Redis of any version, e.g. Redis 2.0, Redis 3.0, Redis 4.0, Redis 5.0. + +**NEVER** run the test program in production envronment, since the keys, which the test program reads or writes, might conflict with your application. + +In order to run tests with both Redis and Redis Cluster, you can run the test program with the following command: + +``` +./compile/test/test_redis++ -h host -p port -a auth -n cluster_node -c cluster_port +``` + +- *host* and *port* are the host and port number of the Redis instance. +- *cluster_node* and *cluster_port* are the host and port number of Redis Cluster. You only need to set the host and port number of a single node in the cluster, *redis-plus-plus* will find other nodes automatically. +- *auth* is the password of the Redis instance and Redis Cluster. The Redis instance and Redis Cluster must be configured with the same password. If there's no password configured, don't set this option. + +If you only want to run tests with Redis, you only need to specify *host*, *port* and *auth* options: + +``` +./compile/test/test_redis++ -h host -p port -a auth +``` + +Similarly, if you only want to run tests with Redis Cluster, just specify *cluster_node*, *cluster_port* and *auth* options: + +``` +./compile/test/test_redis++ -a auth -n cluster_node -c cluster_port +``` + +By default, the test program will not test running *redis-plus-plus* in multi-threads environment. If you want to do multi-threads test, which might cost a long time, you can specify the *-m* option: + +``` +./compile/test/test_redis++ -h host -p port -a auth -n cluster_node -c cluster_port -m +``` + +If all tests have been passed, the test program will print the following message: + +``` +Pass all tests +``` + +Otherwise, it prints the error message. + +#### Performance + +*redis-plus-plus* runs as fast as *hiredis*, since it's a wrapper of *hiredis*. You can run *test_redis++* in benchmark mode to check the performance in your environment. + +``` +./compile/test/test_redis++ -h host -p port -a auth -n cluster_node -c cluster_port -b -t thread_num -s connection_pool_size -r request_num -k key_len -v val_len +``` + +- *-b* option turns the test program into benchmark mode. +- *thread_num* specifies the number of worker threads. `10` by default. +- *connection_pool_size* specifies the size of the connection pool. `5` by default. +- *request_num* specifies the total number of requests sent to server for each test. `100000` by default. +- *key_len* specifies the length of the key for each operation. `10` by default. +- *val_len* specifies the length of the value. `10` by default. + +The bechmark will generate `100` random binary keys for testing, and the size of these keys is specified by *key_len*. When the benchmark runs, it will read/write with these keys. So **NEVER** run the test program in your production environment, otherwise, it might inaccidently delete your data. + +### Use redis-plus-plus In Your Project + +After compiling the code, you'll get both shared library and static library. Since *redis-plus-plus* depends on *hiredis*, you need to link both libraries to your Application. Also don't forget to specify the c++ standard, `-std=c++17`, `-std=c++14` or `-std=c++11`, as well as the thread-related option. + +#### Use Static Libraries + +Take gcc as an example. + +``` +g++ -std=c++17 -o app app.cpp /path/to/libredis++.a /path/to/libhiredis.a -pthread +``` + +If *hiredis* and *redis-plus-plus* are installed at non-default location, you should use `-I` option to specify the header path. + +``` +g++ -std=c++17 -I/non-default/install/include/path -o app app.cpp /path/to/libredis++.a /path/to/libhiredis.a -pthread +``` + +#### Use Shared Libraries + +``` +g++ -std=c++17 -o app app.cpp -lredis++ -lhiredis -pthread +``` + +If *hiredis* and *redis-plus-plus* are installed at non-default location, you should use `-I` and `-L` options to specify the header and library paths. + +``` +g++ -std=c++17 -I/non-default/install/include/path -L/non-default/install/lib/path -o app app.cpp -lredis++ -lhiredis -pthread +``` + +When linking with shared libraries, and running your application, you might get the following error message: + +``` +error while loading shared libraries: xxx: cannot open shared object file: No such file or directory. +``` + +That's because the linker cannot find the shared libraries. In order to solve the problem, you can add the path where you installed *hiredis* and *redis-plus-plus* libraries, to `LD_LIBRARY_PATH` environment variable. For example: + +``` +export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib +``` + +Check [this StackOverflow question](https://stackoverflow.com/questions/480764) for details on how to solve the problem. + +#### Build With Cmake + +If you're using cmake to build your application, you need to add *hiredis* and *redis-plus-plus* dependencies in your *CMakeLists.txt*: + +```CMake +# <---------- set c++ standard -------------> +# NOTE: you must build redis-plus-plus and your application code with the same standard. +set(CMAKE_CXX_STANDARD 17) +set(CMAKE_CXX_STANDARD_REQUIRED ON) + +# <------------ add hiredis dependency ---------------> +find_path(HIREDIS_HEADER hiredis) +target_include_directories(target PUBLIC ${HIREDIS_HEADER}) + +find_library(HIREDIS_LIB hiredis) +target_link_libraries(target ${HIREDIS_LIB}) + +# <------------ add redis-plus-plus dependency --------------> +# NOTE: this should be *sw* NOT *redis++* +find_path(REDIS_PLUS_PLUS_HEADER sw) +target_include_directories(target PUBLIC ${REDIS_PLUS_PLUS_HEADER}) + +find_library(REDIS_PLUS_PLUS_LIB redis++) +target_link_libraries(target ${REDIS_PLUS_PLUS_LIB}) +``` + +See [this issue](https://github.com/sewenew/redis-plus-plus/issues/5) for a complete example of *CMakeLists.txt*. + +Also, if you installed *hiredis* and *redis-plus-plus* at non-default location, you need to run cmake with `CMAKE_PREFIX_PATH` option to specify the installation path of these two libraries. + +``` +cmake -DCMAKE_PREFIX_PATH=/installation/path/to/the/two/libs .. +``` + +## Getting Started + +```C++ +#include + +using namespace sw::redis; + +try { + // Create an Redis object, which is movable but NOT copyable. + auto redis = Redis("tcp://127.0.0.1:6379"); + + // ***** STRING commands ***** + + redis.set("key", "val"); + auto val = redis.get("key"); // val is of type OptionalString.

If the connection is broken, `Redis` reconnects to Redis server automatically. + +You can initialize a `Redis` instance with `ConnectionOptions` and `ConnectionPoolOptions`. `ConnectionOptions` specifies options for connection to Redis server, and `ConnectionPoolOptions` specifies options for conneciton pool. `ConnectionPoolOptions` is optional. If not specified, `Redis` maintains a single connection to Redis server. + +```C++ +ConnectionOptions connection_options; +connection_options.host = "127.0.0.1"; // Required. +connection_options.port = 6666; // Optional. The default port is 6379. +connection_options.password = "auth"; // Optional. No password by default. +connection_options.db = 1; // Optional. Use the 0th database by default. + +// Optional. Timeout before we successfully send request to or receive response from redis. +// By default, the timeout is 0ms, i.e. never timeout and block until we send or receive successfuly. +// NOTE: if any command is timed out, we throw a TimeoutError exception. +connection_options.socket_timeout = std::chrono::milliseconds(200); + +// Connect to Redis server with a single connection. +Redis redis1(connection_options); + +ConnectionPoolOptions pool_options; +pool_options.size = 3; // Pool size, i.e. max number of connections. + +// Optional. Max time to wait for a connection. 0ms by default, which means wait forever. +// Say, the pool size is 3, while 4 threds try to fetch the connection, one of them will be blocked. +pool_options.wait_timeout = std::chrono::milliseconds(100); + +// Optional. Max lifetime of a connection. 0ms by default, which means never expire the connection. +// If the connection has been created for a long time, i.e. more than `connection_lifetime`, +// it will be expired and reconnected. +pool_options.connection_lifetime = std::chrono::minutes(10); + +// Connect to Redis server with a connection pool. +Redis redis2(connection_options, pool_options); +``` + +**NOTE**: if you set `ConnectionOptions::socket_timeout`, and try to call blocking commands, e.g. `Redis::brpop`, `Redis::blpop`, `Redis::bzpopmax`, `Redis::bzpopmin`, you must ensure that `ConnectionOptions::socket_timeout` is larger than the timeout specified with these blocking commands. Otherwise, you might get `TimeoutError`, and lose message. + +See [ConnectionOptions](https://github.com/sewenew/redis-plus-plus/blob/master/src/sw/redis%2B%2B/connection.h#L40) and [ConnectionPoolOptions](https://github.com/sewenew/redis-plus-plus/blob/master/src/sw/redis%2B%2B/connection_pool.h#L30) for more options. Also see [issue 80](https://github.com/sewenew/redis-plus-plus/issues/80) for discussion on connection pool. + +**NOTE**: `Redis` class is movable but NOT copyable. + +```C++ +// auto redis3 = redis1; // this won't compile. + +// But it's movable. +auto redis3 = std::move(redis1); +``` + +*redis-plus-plus* also supports connecting to Redis server with Unix Domain Socket. + +```C++ +ConnectionOptions options; +options.type = ConnectionType::UNIX; +options.path = "/path/to/socket"; +Redis redis(options); +``` + +You can also connect to Redis server with a URI: + +``` +tcp://[[username:]password@]host[:port][/db] + +unix://[[username:]password@]path-to-unix-domain-socket[/db] +``` + +The *scheme* and *host* parts are required, and others are optional. If you're connecting to Redis with Unix Domain Socket, you should use the *unix* scheme, otherwise, you should use *tcp* scheme. The following is a list of default values for those optional parts: + +- username: *default* +- password: empty string, i.e. no password +- port: 6379 +- db: 0 + +**NOTE**: If your password or username contains '@', or your username contains ':', you cannot construct `Redis` object with URI. Because *redis-plus-plus* will incorrectly parse the URI. In this case, you need to use `ConnectionOptions` to construct `Redis` object. + +**NOTE**: [Redis 6.0 supports ACL](https://redis.io/topics/acl), and you can specify a username for the connection. However, before Redis 6.0, you cannot do that. + +Also, the following connection options can be specified with the query string of URI, e.g. *tcp://127.0.0.1?keep_alive=true&socket_timeout=100ms&connect_timeout=100ms*: + +- `ConnectionOptions::keep_alive`: *false* by default. +- `ConnectionOptions::socket_timeout`: *0ms* by default. +- `ConnectionOptions::connect_timeout`: *0ms* by default. + +**NOTE**: Options specified in query string are case-sensitive, i.e. all key-value pairs must be in lowercase. + +So far, you cannot specify connection pool options with URI, e.g. `ConnectionPoolOptions::size`. + +```C++ +// Single connection to the given host and port. +Redis redis1("tcp://127.0.0.1:6666"); + +// Use default port, i.e. 6379. +Redis redis2("tcp://127.0.0.1"); + +// Connect to Redis with password, and default port. +Redis redis3("tcp://pass@127.0.0.1"); + +// Connect to Redis and select the 2nd (db number starts from 0) database. +Redis redis4("tcp://127.0.0.1:6379/2"); + +// Set keep_alive option to true with query string. +Redis redis5("tcp://127.0.0.1:6379/2?keep_alive=true"); + +// Set socket_timeout to 50 milliseconds, and connect_timeout to 1 second with query string. +Redis redis6("tcp://127.0.0.1?socket_timeout=50ms&connect_timeout=1s"); + +// Connect to Unix Domain Socket. +Redis redis7("unix://path/to/socket"); +``` + +#### Lazily Create Connection + +Connections in the pool are lazily created. When the connection pool is initialized, i.e. the constructor of `Redis`, `Redis` does NOT connect to the server. Instead, it connects to the server only when you try to send command. In this way, we can avoid unnecessary connections. So if the pool size is 5, but the number of max concurrent connections is 3, there will be only 3 connections in the pool. + +#### Connection Failure + +You don't need to check whether `Redis` object connects to server successfully. If `Redis` fails to create a connection to Redis server, or the connection is broken at some time, it throws an exception of type `Error` when you try to send command with `Redis`. Even when you get an exception, i.e. the connection is broken, you don't need to create a new `Redis` object. You can reuse the `Redis` object to send commands, and the `Redis` object will try to reconnect to server automatically. If it reconnects successfully, it sends command to server. Otherwise, it throws an exception again. + +See the [Exception section](#exception) for details on exceptions. + +#### Reuse Redis object As Much As Possible + +It's NOT cheap to create a `Redis` object, since it will create new connections to Redis server. So you'd better reuse `Redis` object as much as possible. Also, it's safe to call `Redis`' member functions in multi-thread environment, and you can share `Redis` object in multiple threads. + +```C++ +// This is GOOD practice. +auto redis = Redis("tcp://127.0.0.1"); +for (auto idx = 0; idx < 100; ++idx) { + // Reuse the Redis object in the loop. + redis.set("key", "val"); +} + +// This is VERY BAD! It's very inefficient. +// NEVER DO IT!!! +for (auto idx = 0; idx < 100; ++idx) { + // Create a new Redis object for each iteration. + auto redis = Redis("tcp://127.0.0.1"); + redis.set("key", "val"); +} +``` + +#### TLS/SSL Support + +*redis-plus-plus* also has TLS support. However, in order to use this feature, you need to enable it when building *hiredis* and *redis-plus-plus*. + +**NOTE**: So far, TLS feature has not been tested on Windows platform. I'll fix it in the future. + +##### Enable TLS/SSL support + +When building *hiredis* with TLS support, you need to download *hiredis* of version *v1.0.0* or latter, and specify `USE_SSL=1` flag: + +``` +make PREFIX=/non/default/path USE_SSL=1 + +make PREFIX=/non/default/path USE_SSL=1 install +``` + +Then you can build *redis-plus-plus* to enable TLS support by specifying the `-DREDIS_PLUS_PLUS_USE_TLS=ON` option: + +``` +cmake -DREDIS_PLUS_PLUS_USE_TLS=ON .. +``` + +##### Connection Options + +In order to connect to Redis with TLS support, you need to specify the following connection options: + +``` +ConnectionOptions opts; +opts.host = "127.0.0.1"; +opts.port = 6379; + +opts.tls.enabled = true; // Required. `false` by default. +opts.tls.cert = "/path/to/client/certificate"; // Optional +opts.tls.key = "/path/to/private/key/file"; // Optional +opts.tls.cacert = "/path/to/CA/certificate/file"; // You can also set `opts.tls.cacertdir` instead. +opts.tls.sni = "server-name-indication"; // Optional +``` + +Although `tls.cert` and `tls.key` are optional, if you specify one of them, you must also specify the other. Instead of specifying `tls.cacert`, you can also specify `tls.cacertdir` to the directory where certificates are stored. + +These options are the same as `redis-cli`'s TLS related command line arguments, so you can also run `redis-cli --help` to get the detailed explanation of these options. + +Then you can use this `ConnectionOptions` to create a `Redis` object to connect to Redis server with TLS support. + +**NOTE**: When building your application code, you also need to link it with `libhiredis.a`, `libhiredis_ssl.a`, `libredis++.a` (or the corresponding shared libraries), `-lssl` and `-lcrypto`. + +##### Automatically Initialize OpenSSL Library + +By default, *redis-plus-plus* automatically initializes OpenSSL library, i.e. calls `SSL_library_init` and initializes locks if needed. However, your application code might already initialize OpenSSL library. In this case, you can call `tls::disable_auto_init()` to disable the initialization. You should call this function only once and call it before any other *redis-plus-plus* operation. Otherwise, the behavior is undefined. + +### Send Command to Redis Server + +You can send [Redis commands](https://redis.io/commands) through `Redis` object. `Redis` has one or more (overloaded) methods for each Redis command. The method has the same (lowercased) name as the corresponding command. For example, we have 3 overload methods for the `DEL key [key ...]` command: + +```C++ +// Delete a single key. +long long Redis::del(const StringView &key); + +// Delete a batch of keys: [first, last). +template +long long Redis::del(Input first, Input last); + +// Delete keys in the initializer_list. +template +long long Redis::del(std::initializer_list il); +``` + +With input parameters, these methods build a Redis command based on [Redis protocol](https://redis.io/topics/protocol), and send the command to Redis server. Then synchronously receive the reply, parse it, and return to the caller. + +Let's take a closer look at these methods' parameters and return values. + +#### Parameter Type + +Most of these methods have the same parameters as the corresponding commands. The following is a list of parameter types: + +| Parameter Type | Explaination | Example | Note | +| :------------: | ------------ | ------- | ---- | +| **StringView** | Parameters of string type. Normally used for key, value, member name, field name and so on | ***bool Redis::hset(const StringView &key, const StringView &field, const StringView &val)*** | See the [StringView section](#stringview) for details on `StringView` | +| **long long** | Parameters of integer type. Normally used for index (e.g. list commands) or integer | ***void ltrim(const StringView &key, long long start, long long stop)***
***long long decrby(const StringView &key, long long decrement)*** | | +| **double** | Parameters of floating-point type. Normally used for score (e.g. sorted set commands) or number of floating-point type | ***double incrbyfloat(const StringView &key, double increment)*** | | +| **std::chrono::duration**
**std::chrono::time_point** | Time-related parameters | ***bool expire(const StringView &key, const std::chrono::seconds &timeout)***
***bool expireat(const StringView &key, const std::chrono::time_point &tp)*** | | +| **std::pair** | Used for Redis hash's (field, value) pair | ***bool hset(const StringView &key, const std::pair &item)*** | | +| **std::pair** | Used for Redis geo's (longitude, latitude) pair | ***OptionalLongLong georadius(const StringView &key, const std::pair &location, double radius, GeoUnit unit, const StringView &destination, bool store_dist, long long count)*** | | +| **pair of iterators** | Use a pair of iterators to specify a range of input, so that we can pass the data in a STL container to these methods | ***template < typename Input >***
***long long del(Input first, Input last)*** | Throw an exception, if it's an empty range, i.e. *first == last* | +| **std::initializer_list< T >** | Use an initializer list to specify a batch of input | ***template < typename T >***
***long long del(std::initializer_list< T > il)*** | | +| **some options** | Options for some commands | ***UpdateType***, ***template < typename T > class BoundedInterval*** | See [command_options.h](https://github.com/sewenew/redis-plus-plus/blob/master/src/sw/redis%2B%2B/command_options.h) for details | + +##### StringView + +[std::string_view](http://en.cppreference.com/w/cpp/string/basic_string_view) is a good choice for read-only string parameter types. `std::string_view` was however only introduced in the C++ 17 standard, so if you build *redis-plus-plus* with the `-std=c++11` (i.e. by specifying `-DREDIS_PLUS_PLUS_CXX_STANDARD=11` with cmake command) or the `-std=c++14` standard, a [simple implementation](https://github.com/sewenew/redis-plus-plus/blob/master/src/sw/redis%2B%2B/cxx11/cxx_utils.h) of `std::string_view`, called `StringView`, is available. You could build *redis-plus-plus* with the `-std=c++17` standard (i.e. the default behavior), which will supply `std::string_view` natively. The `StringView` implementation will then be disregarded by aliasing it to `std::string_view`. This is done inside the *redis-plus-plus* library with: `using StringView = std::string_view`. + +Since there are conversions from `std::string` and c-style string to `StringView`, you can just pass `std::string` or c-style string to methods that need a `StringView` parameter. + +```C++ +// bool Redis::hset(const StringView &key, const StringView &field, const StringView &val) + +// Pass c-style string to StringView. +redis.hset("key", "field", "value"); + +// Pass std::string to StringView. +std::string key = "key"; +std::string field = "field"; +std::string val = "val"; +redis.hset(key, field, val); + +// Mix std::string and c-style string. +redis.hset(key, field, "value"); +``` + +#### Return Type + +[Redis protocol](https://redis.io/topics/protocol) defines 5 kinds of replies: +- *Status Reply*: Also known as *Simple String Reply*. It's a non-binary string reply. +- *Bulk String Reply*: Binary safe string reply. +- *Integer Reply*: Signed integer reply. Large enough to hold `long long`. +- *Array Reply*: (Nested) Array reply. +- *Error Reply*: Non-binary string reply that gives error info. + +Also these replies might be *NULL*. For instance, when you try to `GET` the value of a nonexistent key, Redis returns a *NULL Bulk String Reply*. + +As we mentioned above, replies are parsed into return values of these methods. The following is a list of return types: + +| Return Type | Explaination | Example | Note | +| :---------: | ------------ | ------- | ---- | +| **void** | *Status Reply* that should always return a string of "OK" | *RENAME*, *SETEX* | | +| **std::string** | *Status Reply* that NOT always return "OK", and *Bulk String Reply* | *PING*, *INFO* | | +| **bool** | *Integer Reply* that always returns 0 or 1 | *EXPIRE*, *HSET* | See the [Boolean Return Value section](#boolean-return-value) for the meaning of a boolean return value | +| **long long** | *Integer Reply* that not always return 0 or 1 | *DEL*, *APPEND* | | +| **double** | *Bulk String Reply* that represents a double | *INCRBYFLOAT*, *ZINCRBY* | | +| **std::pair** | *Array Reply* with exactly 2 elements. Since the return value is always an array of 2 elements, we return the 2 elements as a `std::pair`'s first and second elements | *BLPOP* | | +| **std::tuple** | *Array Reply* with fixed length and has more than 2 elements. Since length of the returned array is fixed, we return the array as a `std::tuple` | *BZPOPMAX* | | +| **output iterator** | General *Array Reply* with non-fixed/dynamic length. We use STL-like interface to return this kind of array replies, so that you can insert the return value into a STL container easily | *MGET*, *LRANGE* | Also, sometimes the type of output iterator decides which options to send with the command. See the [Examples section](#command-overloads) for details | +| **Optional< T >** | For any reply of type `T` that might be *NULL* | *GET*, *LPOP*, *BLPOP*, *BZPOPMAX* | See the [Optional section](#optional) for details on `Optional` | +| **Variant< Args... >** | For reply that might be of serval different types | *MEMORY STATS* | NOTE: so far, this type is only supported when compiling redis-plus-plus with C++ 17 standard. This is normally used with [generic command interface](https://github.com/sewenew/redis-plus-plus#generic-command-interface). See the [Variant section](#variant) for details on `Variant` | +| **STL container** | General *Array Reply* | *CONFIG GET* | Both *output iterator* and *STL container* are used for array reply. The difference is that *STL container* is normally used with [generic command interface](https://github.com/sewenew/redis-plus-plus#generic-command-interface). See the [STL container section](#stl-container) for example | + +##### Boolean Return Value + +The return type of some methods, e.g. `EXPIRE`, `HSET`, is `bool`. If the method returns `false`, it DOES NOT mean that `Redis` failed to send the command to Redis server. Instead, it means that Redis server returns an *Integer Reply*, and the value of the reply is `0`. Accordingly, if the method returns `true`, it means that Redis server returns an *Integer Reply*, and the value of the reply is `1`. You can +check [Redis commands manual](http://redis.io/commands) for what do `0` and `1` stand for. + +For example, when we send `EXPIRE` command to Redis server, it returns `1` if the timeout was set, and it returns `0` if the key doesn't exist. Accordingly, if the timeout was set, `Redis::expire` returns `true`, and if the key doesn't exist, `Redis::expire` returns `false`. + +So, never use the return value to check if the command has been successfully sent to Redis server. Instead, if `Redis` failed to send command to server, it throws an exception of type `Error`. See the [Exception section](#exception) for details on exceptions. + +##### Optional + +[std::optional](http://en.cppreference.com/w/cpp/utility/optional) is a good option for return type, if Redis might return *NULL REPLY*. However, `std::optional` is introduced in C++ 17 standard, and if you build *redis-plus-plus* with `-std=c++11` standard (i.e. by specifying `-DREDIS_PLUS_PLUS_CXX_STANDARD=11` with cmake command), we implement our own [simple version](https://github.com/sewenew/redis-plus-plus/blob/master/src/sw/redis%2B%2B/cxx11/cxx_utils.h), i.e. `template Optional`. Instead, if you build *redis-plus-plus* with `-std=c++17` standard (i.e. the default behavior), you can use `std::optional`, and we have an alias for it: `template using Optional = std::optional`. + +Take the [GET](https://redis.io/commands/get) and [MGET](https://redis.io/commands/mget) commands for example: + +```C++ +// Or just: auto val = redis.get("key"); +Optional val = redis.get("key"); + +// Optional has a conversion to bool. +// If it's NOT a null Optional object, it's converted to true. +// Otherwise, it's converted to false. +if (val) { + // Key exists. Dereference val to get the string result. + std::cout << *val << std::endl; +} else { + // Redis server returns a NULL Bulk String Reply. + // It's invalid to dereference a null Optional object. + std::cout << "key doesn't exist." << std::endl; +} + +std::vector> values; +redis.mget({"key1", "key2", "key3"}, std::back_inserter(values)); +for (const auto &val : values) { + if (val) { + // Key exist, process the value. + } +} +``` + +We also have some typedefs for some commonly used `Optional`: + +```C++ +using OptionalString = Optional; + +using OptionalLongLong = Optional; + +using OptionalDouble = Optional; + +using OptionalStringPair = Optional>; +``` + +##### Variant + +[std::variant](https://en.cppreference.com/w/cpp/utility/variant) is a good option for return type, if the reply might be of different types. For example, the `MEMORY STATS` command returns an array reply, which is, in fact, a map of key-value pairs of configurations: + +``` +127.0.0.1:6379> memory stats + 1) "peak.allocated" + 2) (integer) 4471104 + ... +17) "db.0" +18) 1) "overhead.hashtable.main" + 2) (integer) 104 + 3) "overhead.hashtable.expires" + 4) (integer) 32 +... +27) "dataset.percentage" +28) "9.70208740234375" +... +``` + +However, as you can see, the value part of the result might be of type long long (key: *peak.allocated*), double (key: *dataset.percentage*) or even a map (key: *db.0*). So you cannot simply parse the result into a `std::unordered_map` or `std::unordered_map`. A workaround is to parse the result into a `tuple`, however, this tuple solution is ugly and error-prone. Check [this issue](https://github.com/sewenew/redis-plus-plus/issues/138) for detail. + +In this case, `Variant`, which is a typedef of `std::variant` if you build redis-plus-plus with C++17 standard, is very helpful. You can parse the result into a `std::unordered_map>>`. + +``` +using Var = Variant>; +auto r = Redis("tcp://127.0.0.1"); +auto v = r.command>("memory", "stats"); +``` + +There're some limitations on `Variant` support: + +- The type arguments of `Variant`, cannot have duplicate items, e.g. `Variant` won't work. +- `double` must be placed before `std::string`. Because `double` reply is, in fact, string reply, and when parsing variant, we try to parse the reply into the first matched type, specified with the type arguments from left to right. So if `double` is placed after `std::string`, i.e. on the right side of `std::string`, the reply will always be parsed into `std::string`. + +Also check the [generic command section](https://github.com/sewenew/redis-plus-plus#generic-command-interface) for more examples on generic command interface. + +##### STL container + +When using generic command interface, instead of parsing the reply to output iterator, you can also parse it into a STL container. + +``` +auto r = Redis("tcp://127.0.0.1"); +auto v = r.command>("config", "get", "*"); +``` + +Also check the [generic command section](https://github.com/sewenew/redis-plus-plus#generic-command-interface) for more examples on generic command interface. + +#### Examples + +Let's see some examples on how to send commands to Redis server. + +##### Various Parameter Types + +```C++ +// ***** Parameters of StringView type ***** + +// Implicitly construct StringView with c-style string. +redis.set("key", "value");

All exceptions derived from `Error` class. See [errors.h](https://github.com/sewenew/redis-plus-plus/blob/master/src/sw/redis%2B%2B/errors.h) for details. + +- `Error`: Generic error. It's derived from `std::exception`, and it's also the base class of other exceptions. +- `IoError`: There's some IO error with the connection. +- `TimeoutError`: Read or write operation was timed out. It's a derived class of `IoError`. +- `ClosedError`: Redis server closed the connection. +- `ProtoError`: The command or reply is invalid, and we cannot process it with Redis protocol. +- `OomError`: *hiredis* library got an out-of-memory error. +- `ReplyError`: Redis server returned an error reply, e.g. we try to call `redis::lrange` on a Redis hash. +- `WatchError`: Watched key has been modified. See [Watch section](#watch) for details. + +**NOTE**: *NULL REPLY* is not taken as an exception. For example, if we try to `GET` a non-existent key, we'll get a *NULL Bulk String Reply*. Instead of throwing an exception, we return the *NULL REPLY* as a null `Optional` object. Also see [Optional section](#optional). + +Normally, when exception happens, you don't need to create a `Redis` object. It's exception safe, and you can reuse the `Redis` object. Even if the connection to Redis server is broken, and it throws some exception, say, `IoError`. The next time when you send command with the `Redis` object, it will try to reconnect to Redis server automatically. This rule also applies to `RedisCluster`. However, if `Pipeline`, `Transcation` and `Subscriber` throws exception, you need to destroy the object, and create a new one. See the corresponding documentation for details. + +#### Examples + +The following is an example on how to catch these exceptions: + +``` +try { + redis.set("key", "value"); + + // Wrong type error + redis.lpush("key", {"a", "b", "c"}); +} catch (const ReplyError &err) { + // WRONGTYPE Operation against a key holding the wrong kind of value + cout << err.what() << endl; +} catch (const TimeoutError &err) { + // reading or writing timeout +} catch (const ClosedError &err) { + // the connection has been closed. +} catch (const IoError &err) { + // there's an IO error on the connection. +} catch (const Error &err) { + // other errors +} +``` + +### Generic Command Interface + +There're too many Redis commands, we haven't implemented all of them. However, you can use the generic `Redis::command` methods to send any commands to Redis. Unlike other client libraries, `Redis::command` doesn't use format string to combine command arguments into a command string. Instead, you can directly pass command arguments of `StringView` type or arithmetic type as parameters of `Redis::command`. For the reason why we don't use format string, please see [this discussion](https://github.com/sewenew/redis-plus-plus/pull/2). + +```C++ +auto redis = Redis("tcp://127.0.0.1"); + +// Redis class doesn't have built-in *CLIENT SETNAME* method. +// However, you can use Redis::command to send the command manually. +redis.command("client", "setname", "name"); +auto val = redis.command("client", "getname"); +if (val) { + std::cout << *val << std::endl; +} + +// NOTE: the following code is for example only. In fact, Redis has built-in +// methods for the following commands. + +// Arguments of the command can be strings. +// NOTE: for SET command, the return value is NOT always void, I'll explain latter. +redis.command("set", "key", "100"); + +// Arguments of the command can be a combination of strings and integers. +auto num = redis.command("incrby", "key", 1); + +// Argument can also be double. +auto real = redis.command("incrbyfloat", "key", 2.3); + +// Even the key of the command can be of arithmetic type. +redis.command("set", 100, "value"); + +val = redis.command("get", 100); + +// If the command returns an array of elements. +std::vector result; +redis.command("mget", "k1", "k2", "k3", std::back_inserter(result)); + +// Or just parse it into a vector. +result = redis.command>("mget", "k1", "k2", "k3"); + +// Arguments of the command can be a range of strings. +auto set_cmd_strs = {"set", "key", "value"}; +redis.command(set_cmd_strs.begin(), set_cmd_strs.end()); + +auto get_cmd_strs = {"get", "key"}; +val = redis.command(get_cmd_strs.begin(), get_cmd_strs.end()); + +// If it returns an array of elements. +result.clear(); +auto mget_cmd_strs = {"mget", "key1", "key2"}; +redis.command(mget_cmd_strs.begin(), mget_cmd_strs.end(), std::back_inserter(result)); +``` + +**NOTE**: The name of some Redis commands is composed with two strings, e.g. *CLIENT SETNAME*. In this case, you need to pass these two strings as two arguments for `Redis::command`. + +```C++ +// This is GOOD. +redis.command("client", "setname", "name"); + +// This is BAD, and will fail to send command to Redis server. +// redis.command("client setname", "name"); +``` + +As I mentioned in the comments, the `SET` command not always returns `void`. Because if you try to set a (key, value) pair with *NX* or *XX* option, you might fail, and Redis will return a *NULL REPLY*. Besides the `SET` command, there're other commands whose return value is NOT a fixed type, you need to parse it by yourself. For example, `Redis::set` method rewrite the reply of `SET` command, and make it return `bool` type, i.e. if no *NX* or *XX* option specified, Redis server will always return an "OK" string, and `Redis::set` returns `true`; if *NX* or *XX* specified, and Redis server returns a *NULL REPLY*, `Redis::set` returns `false`. + +So `Redis` class also has other overloaded `command` methods, these methods return a `ReplyUPtr`, i.e. `std::unique_ptr`, object. Normally you don't need to parse it manually. Instead, you only need to pass the reply to `template T reply::parse(redisReply &)` to get a value of type `T`. Check the [Return Type section](#return-type) for valid `T` types. If the command returns an array of elements, besides calling `reply::parse` to parse the reply to an STL container, you can also call `template reply::to_array(redisReply &reply, Output output)` to parse the result into an array or STL container with an output iterator. + +Let's rewrite the above examples: + +```C++ +auto redis = Redis("tcp://127.0.0.1"); + +redis.command("client", "setname", "name"); +auto r = redis.command("client", "getname"); +assert(r); + +// If the command returns a single element, +// use `reply::parse(redisReply&)` to parse it. +auto val = reply::parse(*r); +if (val) { + std::cout << *val << std::endl; +} + +// Arguments of the command can be strings. +redis.command("set", "key", "100"); + +// Arguments of the command can be a combination of strings and integers. +r = redis.command("incrby", "key", 1); +auto num = reply::parse(*r); + +// Argument can also be double. +r = redis.command("incrbyfloat", "key", 2.3); +auto real = reply::parse(*r); + +// Even the key of the command can be of arithmetic type. +redis.command("set", 100, "value"); + +r = redis.command("get", 100); +val = reply::parse(*r); + +// If the command returns an array of elements. +r = redis.command("mget", "k1", "k2", "k3"); +// Use `reply::to_array(redisReply&, OutputIterator)` to parse the result into an STL container. +std::vector result; +reply::to_array(*r, std::back_inserter(result)); + +// Or just call `reply::parse` to parse it into vector. +result = reply::parse>(*r); + +// Arguments of the command can be a range of strings. +auto get_cmd_strs = {"get", "key"}; +r = redis.command(get_cmd_strs.begin(), get_cmd_strs.end()); +val = reply::parse(*r); + +// If it returns an array of elements. +result.clear(); +auto mget_cmd_strs = {"mget", "key1", "key2"}; +r = redis.command(mget_cmd_strs.begin(), mget_cmd_strs.end()); +reply::to_array(*r, std::back_inserter(result)); +``` + +In fact, there's one more `Redis::command` method: + +```C++ +template +auto command(Cmd cmd, Args &&...args) + -> typename std::enable_if::value, ReplyUPtr>::type; +``` + +However, this method exposes some implementation details, and is only for internal use. You should NOT use this method. + +### Publish/Subscribe + +You can use `Redis::publish` to publish messages to channels. `Redis` randomly picks a connection from the underlying connection pool, and publishes message with that connection. So you might publish two messages with two different connections. + +When you subscribe to a channel with a connection, all messages published to the channel are sent back to that connection. So there's NO `Redis::subscribe` method. Instead, you can call `Redis::subscriber` to create a `Subscriber` and the `Subscriber` maintains a connection to Redis. The underlying connection is a new connection, NOT picked from the connection pool. This new connection has the same `ConnectionOptions` as the `Redis` object. + +With `Subscriber`, you can call `Subscriber::subscribe`, `Subscriber::unsubscribe`, `Subscriber::psubscribe` and `Subscriber::punsubscribe` to send *SUBSCRIBE*, *UNSUBSCRIBE*, *PSUBSCRIBE* and *PUNSUBSCRIBE* commands to Redis. + +#### Thread Safety + +`Subscriber` is NOT thread-safe. If you want to call its member functions in multi-thread environment, you need to synchronize between threads manually. + +#### Exception + +If any of the `Subscriber`'s method throws an exception other than `ReplyError` or `TimeoutError`, you CANNOT use it any more. Instead, you have to destroy the `Subscriber` object, and create a new one. + +#### Subscriber Callbacks + +There are 6 kinds of messages: +- *MESSAGE*: message sent to a channel. +- *PMESSAGE*: message sent to channels of a given pattern. +- *SUBSCRIBE*: message sent when we successfully subscribe to a channel. +- *UNSUBSCRIBE*: message sent when we successfully unsubscribe to a channel. +- *PSUBSCRIBE*: message sent when we successfully subscribe to a channel pattern. +- *PUNSUBSCRIBE*: message sent when we successfully unsubscribe to a channel pattern. + +We call messages of *SUBSCRIBE*, *UNSUBSCRIBE*, *PSUBSCRIBE* and *PUNSUBSCRIBE* types as *META MESSAGE*s. + +In order to process these messages, you can set callback functions on `Subscriber`: +- `Subscriber::on_message(MsgCallback)`: set callback function for messages of *MESSAGE* type, and the callback interface is: `void (std::string channel, std::string msg)`. +- `Subscriber::on_pmessage(PatternMsgCallback)`: set the callback function for messages of *PMESSAGE* type, and the callback interface is: `void (std::string pattern, std::string channel, std::string msg)`. +- `Subscriber::on_meta(MetaCallback)`: set callback function for messages of *META MESSAGE* type, and the callback interface is: `void (Subscriber::MsgType type, OptionalString channel, long long num)`. `type` is an enum, it can be one of the following enum: `Subscriber::MsgType::SUBSCRIBE`, `Subscriber::MsgType::UNSUBSCRIBE`, `Subscriber::MsgType::PSUBSCRIBE`, `Subscriber::MsgType::PUNSUBSCRIBE`, `Subscriber::MsgType::MESSAGE`, and `Subscriber::MsgType::PMESSAGE`. If you haven't subscribe/psubscribe to any channel/pattern, and try to unsubscribe/punsubscribe without any parameter, i.e. unsubscribe/punsubscribe all channels/patterns, *channel* will be null. So the second parameter of meta callback is of type `OptionalString`. + +All these callback interfaces pass `std::string` by value, and you can take their ownership (i.e. `std::move`) safely. + +#### Consume Messages + +You can call `Subscriber::consume` to consume messages published to channels/patterns that the `Subscriber` has been subscribed. + +`Subscriber::consume` waits for message from the underlying connection. If the `ConnectionOptions::socket_timeout` is reached, and there's no message sent to this connection, `Subscriber::consume` throws a `TimeoutError` exception. If `ConnectionOptions::socket_timeout` is `0ms`, `Subscriber::consume` blocks until it receives a message. + +After receiving the message, `Subscriber::consume` calls the callback function to process the message based on message type. However, if you don't set callback for a specific kind of message, `Subscriber::consume` will consume the received message and discard it, i.e. `Subscriber::consume` returns without running the callback. + +#### Examples + +The following example is a common pattern for using `Subscriber`: + +```C++ +// Create a Subscriber. +auto sub = redis.subscriber(); + +// Set callback functions. +sub.on_message([](std::string channel, std::string msg) { + // Process message of MESSAGE type. + }); + +sub.on_pmessage([](std::string pattern, std::string channel, std::string msg) { + // Process message of PMESSAGE type. + }); + +sub.on_meta([](Subscriber::MsgType type, OptionalString channel, long long num) { + // Process message of META type. + }); + +// Subscribe to channels and patterns. +sub.subscribe("channel1"); +sub.subscribe({"channel2", "channel3"}); + +sub.psubscribe("pattern1*"); + +// Consume messages in a loop. +while (true) { + try { + sub.consume(); + } catch (const Error &err) { + // Handle exceptions. + } +} +``` + +If `ConnectionOptions::socket_timeout` is set, you might get `TimeoutError` exception before receiving a message: + +```C++ +while (true) { + try { + sub.consume(); + } catch (const TimeoutError &e) { + // Try again. + continue; + } catch (const Error &err) { + // Handle other exceptions. + } +} +``` + +The above examples use lambda as callback. If you're not familiar with lambda, you can also set a free function as callback. Check [this issue](https://github.com/sewenew/redis-plus-plus/issues/16) for detail. + +### Pipeline + +[Pipeline](https://redis.io/topics/pipelining) is used to reduce *RTT* (Round Trip Time), and speed up Redis queries. *redis-plus-plus* supports pipeline with the `Pipeline` class. + +#### Create Pipeline + +You can create a pipeline with `Redis::pipeline` method, which returns a `Pipeline` object. + +```C++ +ConnectionOptions connection_options; +ConnectionPoolOptions pool_options; + +Redis redis(connection_options, pool_options); + +auto pipe = redis.pipeline(); +``` + +When creating a `Pipeline` object, by default, `Redis::pipeline` method creates a new connection to Redis server. This connection is NOT picked from the connection pool, but a newly created connection. This connection has the same `ConnectionOptions` as other connections in the connection pool. `Pipeline` object maintains the new connection, and all piped commands are sent through this connection. + +**NOTE**: By default, creating a `Pipeline` object is NOT cheap, since it creates a new connection. So you'd better reuse the `Pipeline` object as much as possible. Check [this](#create-pipeline-without-creating-new-connection) to see how to create a `Pipeline` object without creating a new connection. + +#### Send Commands + +You can send Redis commands through the `Pipeline` object. Just like the `Redis` class, `Pipeline` has one or more (overloaded) methods for each Redis command. However, you CANNOT get the replies until you call `Pipeline::exec`. So these methods do NOT return the reply, instead they return the `Pipeline` object itself. And you can chain these methods calls. + +```C++ +pipe.set("key", "val").incr("num").rpush("list", {0, 1, 2}).command("hset", "key", "field", "value"); +``` + +#### Get Replies + +Once you finish sending commands to Redis, you can call `Pipeline::exec` to get replies of these commands. You can also chain `Pipeline::exec` with other commands. + +```C++ +pipe.set("key", "val").incr("num"); +auto replies = pipe.exec(); + +// The same as: +replies = pipe.set("key", "val").incr("num).exec(); +``` + +In fact, these commands won't be sent to Redis, until you call `Pipeline::exec`. So `Pipeline::exec` does 2 work in order: send all piped commands, then get all replies from Redis. + +Also you can call `Pipeline::discard` to discard those piped commands. + +```C++ +pipe.set("key", "val").incr("num"); + +pipe.discard(); +``` + +#### Parse Replies + +`Pipeline::exec` returns a `QueuedReplies` object, which contains replies of all commands that have been sent to Redis. You can use `QueuedReplies::get` method to get and parse the `ith` reply. It has 3 overloads: + +- `template Result get(std::size_t idx)`: Return the `ith` reply as a return value, and you need to specify the return type as tempalte parameter. +- `template void get(std::size_t idx, Output output)`: If the reply is of type *Array Reply*, you can call this method to write the `ith` reply to an output iterator. Normally, compiler will deduce the type of the output iterator, and you don't need to specify the type parameter explicitly. +- `redisReply& get(std::size_t idx)`: If the reply is NOT a fixed type, call this method to get a reference to `redisReply` object. In this case, you need to call `template T reply::parse(redisReply &)` to parse the reply manually. + +Check the [Return Type section](#return-type) for details on the return types of the result. + +```C++ +auto replies = pipe.set("key", "val").incr("num").lrange("list", 0, -1).exec(); + +auto set_cmd_result = replies.get(0); + +auto incr_cmd_result = replies.get(1); + +std::vector list_cmd_result; +replies.get(2, std::back_inserter(list_cmd_result)); +``` + +#### Exception + +If any of `Pipeline`'s method throws an exception other than `ReplyError`, the `Pipeline` object enters an invalid state. You CANNOT use it any more, but only destroy the object, and create a new one. + +#### Thread Safety + +`Pipeline` is NOT thread-safe. If you want to call its member functions in multi-thread environment, you need to synchronize between threads manually. + +#### Create Pipeline Without Creating New Connection + +**YOU MUST CAREFULLY READ ALL WORDS IN THIS SECTION AND THE VERY IMPORTANT NOTES BEFORE USING THIS FEATURE!!!** + +In fact, you can also create a `Pipeline` object with a connection from the underlying connection pool, so that calling `Redis::pipeline` method can be much cheaper (since it doesn't need to create a new connection). + +The prototype of `Redis::pipeline` is as follows: `Pipeline pipeline(bool new_connection = true);`. If `new_connection` is false, the `Pipeline` object will be created with a connection from the underlying pool. + +``` +ConnectionOptions connection_options; +ConnectionPoolOptions pool_options; + +Redis redis(connection_options, pool_options); + +// Create a Pipeline without creating a new connection. +auto pipe = redis.pipeline(false); +``` + +##### VERY IMPORTANT NOTES + +However, in this case, you MUST be very careful, otherwise, you might get bad performance or even dead lock. Because when you run command with `Pipeline` object, it will hold the connection until `Pipeline::exec`, `Pipeline::discard` or `Pipeline`'s destructor is called (the connection will also be released if any method of `Pipeline` throws `Exception`). If the `Pipeline` object holds the connection for a long time, other `Redis` methods might not be able to get a connection from the underlying pool. + +Check the following dead lock example: + +``` +// By defaul, create a `Redis` object with only ONE connection in pool. +// Also by default, the `ConnectionPoolOptions::wait_timeout` is 0ms, +// which means if the pool is empty, `Redis` method will be blocked until +// the pool is not empty. +Redis redis("tcp://127.0.0.1"); + +// Create a `Pipeline` with a connection in the underlying pool. +// In fact, the connection hasn't been fetched from the pool +// until some method of `Pipeline` has been called. +auto pipe = redis.pipeline(false); + +// Now the `Pipeline` object fetches a connection from the pool. +pipe.set("key1", "val"); + +// `Pipeline` object still holds the connection until `Pipeline::exec`, +// `Pipeline::discard` or the destructor is called. +pipe.set("key2", "val"); + +// Try to send a command with `Redis` object. +// However, the pool is empty, since the `Pipeline` object still holds +// the connection, and this call will be blocked forever. +// DEAD LOCK!!! +redis.get("key"); + +// NEVER goes here. +pipe.exec(); +``` + +**BEST PRACTICE**: + +When creating `Pipeline` without creating a new connection: + +- Always set `ConnectionPoolOptions::wait_timeout` larger than 0ms (i.e. when pool is empty, never block forever). +- Avoid doing slow operation between `Pipeline`'s methods. +- Better chain `Pipeline` methods and the `Pipeline::exec` in one statements. +- Better leave `Pipeline` related code in a block scope. + +``` +ConnectionOptions opts; +opts.host = "127.0.0.1"; +opts.port = 6379; +opts.socket_timeout = std::chrono::milliseconds(50); + +ConnectionPoolOptions pool_opts; +pool_opts.size = 3; + +// Always set `wait_timeout` larger than 0ms. +pool_opts.wait_timeout = std::chrono::milliseconds(50); + +auto redis = Redis(opts, pool_opts); + +{ + // Better put `Pipeline` related code in a block scope. + auto pipe = redis.pipeline(false); + + pipe.set("key1", "val"); + + // DON'T run slow operations here, since `Pipeline` object still holds + // the connection, other threads using this `Redis` object, might be blocked. + + pipe.set("key2", "val"); + + // When `Pipeline::exec` finishes, `Pipeline` releases the connection, and returns it to pool. + auto replies = pipe.exec(); + + // This is even better, i.e. chain `Pipeline` methods with `Pipeline::exec`. + replies = pipe.set("key1", "val").set("key2", "val").exec(); +} + +for (auto i = 0; i < 10; ++i) { + // This operation, i.e. creating a `Pipeline` object with connection in pool, is cheap + auto pipe = redis.pipeline(false); + + // Fetch a connection from the underlying pool, and hold it. + pipe.set("key1", "val").set("key2", "val"); + + // Although `Pipeline::exec` and `Pipeline::discard` haven't been called, + // when `Pipeline`'s destructor is called, the connection will also be + // returned to the pool. +} +``` + +### Transaction + +[Transaction](https://redis.io/topics/transactions) is used to make multiple commands runs atomically. + +#### Create Transaction + +You can create a transaction with `Redis::transaction` method, which returns a `Transaction` object. + +```C++ +ConnectionOptions connection_options; +ConnectionPoolOptions pool_options; + +Redis redis(connection_options, pool_options); + +auto tx = redis.transaction(); +``` + +As the `Pipeline` class, `Transaction` maintains a newly created connection to Redis. This connection has the same `ConnectionOptions` as the `Redis` object. + +**NOTE**: Creating a `Transaction` object is NOT cheap, since it creates a new connection. So you'd better reuse the `Transaction` as much as possible. Check [this](#create-transaction-without-creating-new-connection) to see how to create a `Transaction` object without creating a new connection. + +Also you don't need to send [MULTI](https://redis.io/commands/multi) command to Redis. `Transaction` will do that for you automatically. + +#### Send Commands + +`Transaction` shares most of implementation with `Pipeline`. It has the same interfaces as `Pipeline`. You can send commands as what you do with `Pipeline` object. + +```C++ +tx.set("key", "val").incr("num").lpush("list", {0, 1, 2}).command("hset", "key", "field", "val"); +``` + +#### Execute Transaction + +When you call `Transaction::exec`, you explicitly ask Redis to execute those queued commands, and return the replies. Otherwise, these commands won't be executed. Also, you can call `Transaction::discard` to discard the execution, i.e. no command will be executed. Both `Transaction::exec` and `Transaction::discard` can be chained with other commands. + +```C++ +auto replies = tx.set("key", "val").incr("num").exec(); + +tx.set("key", "val").incr("num"); + +// Discard the transaction. +tx.discard(); +``` + +#### Parse Replies + +See [Pipeline's Parse Replies section](#parse-replies) for how to parse the replies. + +#### Piped Transaction + +Normally, we always send multiple commnds in a transaction. In order to improve the performance, you can send these commands in a pipeline. You can create a piped transaction by passing `true` as parameter of `Redis::transaction` method. + +```C++ +// Create a piped transaction +auto tx = redis.transaction(true); +``` + +With this piped transaction, all commands are sent to Redis in a pipeline. + +#### Exception + +If any of `Transaction`'s method throws an exception other than `WatchError` or `ReplyError`, the `Transaction` object enters an invalid state. You CANNOT use it any more, but only destroy the object and create a new one. + +#### Thread Safety + +`Transacation` is NOT thread-safe. If you want to call its member functions in multi-thread environment, you need to synchronize between threads manually. + +#### Watch + +[WATCH is used to provide a check-and-set(CAS) behavior to Redis transactions](https://redis.io/topics/transactions#optimistic-locking-using-check-and-set). + +The `WATCH` command must be sent in the same connection as the transaction. And normally after the `WATCH` command, we also need to send some other commands to get data from Redis before executing the transaction. Take the following check-and-set case as an example: + +``` +WATCH key // watch a key +val = GET key // get value of the key +new_val = val + 1 // incr the value +MULTI // begin the transaction +SET key new_val // set value only if the value is NOT modified by others +EXEC // try to execute the transaction. + // if val has been modified, the transaction won't be executed. +``` + +However, with `Transaction` object, you CANNOT get the result of commands until the whole transaction has been finished. Instead, you need to create a `Redis` object from the `Transaction` object. The created `Redis` object shares the connection with `Transaction` object. With this created `Redis` object, you can send `WATCH` command and any other Redis commands to Redis server, and get the result immediately. + +Let's see how to implement the above example with *redis-plus-plus*: + +```C++ +auto redis = Redis("tcp://127.0.0.1"); + +// Create a transaction. +auto tx = redis.transaction(); + +// Create a Redis object from the Transaction object. Both objects share the same connection. +auto r = tx.redis(); + +// If the watched key has been modified by other clients, the transaction might fail. +// So we need to retry the transaction in a loop. +while (true) { + try { + // Watch a key. + r.watch("key"); + + // Get the old value. + auto val = r.get("key"); + auto num = 0; + if (val) { + num = std::stoi(*val); + } // else use default value, i.e. 0. + + // Incr value. + ++num; + + // Execute the transaction. + auto replies = tx.set("key", std::to_string(num)).exec(); + + // Transaction has been executed successfully. Check the result and break. + + assert(replies.size() == 1 && replies.get(0) == true); + + break; + } catch (const WatchError &err) { + // Key has been modified by other clients, retry. + continue; + } catch (const Error &err) { + // Something bad happens, and the Transaction object is no longer valid. + throw; + } +} +``` + +**NOTE**: in the example above, we create `Transaction` object outside the while loop, in order to avoid creating new connection again and again. + +#### Create Transaction Without Creating New Connection + +**NOTE**: YOU MUST CAREFULLY READ ALL WORDS AND THE VERY IMPORTANT NOTES LINK IN THIS SECTION BEFORE USING THIS FEATURE!!! + +In fact, you can also create a `transaction` object with a connection from the underlying connection pool, so that calling `Redis::transaction` method can be much cheaper (since it doesn't need to create a new connection). + +The prototype of `Redis::transaction` is as follows: `Transaction transaction(bool piped = false, bool new_connection = true);`.

Please carefully check the similar pipeline's [VERY IMPORTANT NOTES section](#very-important-notes), before you use it! + +Besides those very important notes, there's another important note for `Transaction`: + +- Limit the scope of `Redis` object created by `Transaction::Redis`, i.e. destroy it ASAP. + +Check the following example: + +```C++ +auto redis = Redis(opts, pool_opts); + +// Create a `Transaction` object without creating a new connection. +auto tx = redis.Transaction(false, false); + +// Create a `Redis`, and this `Redis` object shares the same connection with the `Transaction` object. +auto r = tx.redis(); + +// Other code here... + +// Execute the transaction. +auto replies = tx.set("key", "val").exec(); + +// Although `Transaction::exec` has been called, the connection has not been returned to pool. +// Because the `Redis` object, i.e. `r`, still holds the connection. +``` + +So the above watch example should be modified as follows: + +```C++ +auto redis = Redis(opts, pool_opts); + +// If the watched key has been modified by other clients, the transaction might fail. +// So we need to retry the transaction in a loop. +while (true) { + try { + // Create a transaction without creating a new connection. + auto tx = redis.transaction(false, false); + + // Create a Redis object from the Transaction object.

When the `Transaction` object and the `Redis` object created by `Transaction::redis` have been destroyed, the connection will be return to pool. + +### Redis Cluster + +*redis-plus-plus* supports [Redis Cluster](https://redis.io/topics/cluster-tutorial). You can use `RedisCluster` class to send commands to Redis Cluster. It has similar interfaces as `Redis` class. + +#### Connection + +By default, `RedisCluster` connects to all master nodes in the cluster. For each master node, it maintains a connection pool. If you want to read from slave nodes, you need to explicitly set an option (see [below](#read-from-replica) for reference). + +You can initialize a `RedisCluster` instance with `ConnectionOptions` and `ConnectionPoolOptions`. You only need to set one master node's host & port in `ConnectionOptions`, and `RedisCluster` will get other nodes' info automatically (with the *CLUSTER SLOTS* command). For each master node, it creates a connection pool with the specified `ConnectionPoolOptions`. If `ConnectionPoolOptions` is not specified, `RedisCluster` maintains a single connection to every master node. + +```C++ +// Set a master node's host & port. +ConnectionOptions connection_options; +connection_options.host = "127.0.0.1"; // Required. +connection_options.port = 7000; // Optional. The default port is 6379. +connection_options.password = "auth"; // Optional. No password by default. + +// Automatically get other nodes' info, +// and connect to every master node with a single connection. +RedisCluster cluster1(connection_options); + +ConnectionPoolOptions pool_options; +pool_options.size = 3; + +// For each master node, maintains a connection pool of size 3. +RedisCluster cluster2(connection_options, pool_options); +``` + +You can also specify connection option with an URI. However, in this way, you can only use default `ConnectionPoolOptions`, i.e. pool of size 1, and CANNOT specify password. + +```C++ +// Specify a master node's host & port. +RedisCluster cluster3("tcp://127.0.0.1:7000"); + +// Use default port, i.e. 6379. +RedisCluster cluster4("tcp://127.0.0.1"); +``` + +##### Read From Replica + +If you want to scale read by reading (possible stale) data from slave nodes, you can specifiy `Role::SLAVE` as the third parameter of `RedisCluster`'s constructor. In this case, *redis-plus-plus* will randomly pick a replica node for each master node of the cluster, and create a connection pool for the replica node. + +```C++ +RedisCluster cluster(connection_options, pool_options, Role::SLAVE); + +auto val = cluster.get("key"); +``` + +In this case, you can only send readonly commands to Redis Cluster. If you try to send a write command, e.g. `set`, `hset`, *redis-plus-plus* will throw an exception. Currently, *redis-plus-plus* doesn't handle this case, i.e. sending write command in `Role::SLAVE` mode, elegantly, and you might get some performance problem. So, NEVER send write command in `Role::SLAVE` mode. I'll fix this issue in the future. + +**NOTE**: In `Role::SLAVE` mode, you don't need to manually send [READONLY](https://redis.io/commands/readonly) command to slave nodes. Instead, *redis-plus-plus* will send *READONLY* command to slave nodes automatically. + +##### Note + +- `RedisCluster` only works with tcp connection. It CANNOT connect to Unix Domain Socket. If you specify Unix Domain Socket in `ConnectionOptions`, it throws an exception. +- All nodes in the cluster should have the same password. +- Since [Redis Cluster does NOT support multiple databses](https://redis.io/topics/cluster-spec#implemented-subset), `ConnectionOptions::db` is ignored. + +#### Interfaces + +As we mentioned above, `RedisCluster`'s interfaces are similar to `Redis`. It supports most of `Redis`' interfaces, including the [generic command interface](#generic-command-interface) (see `Redis`' [API Reference section](#api-reference) for details), except the following: + +- Not support commands without key as argument, e.g. `PING`, `INFO`. +- Not support Lua script without key parameters. + +Since there's no key parameter, `RedisCluster` has no idea on to which node these commands should be sent. However there're 2 workarounds for this problem: + +- If you want to send these commands to a specific node, you can create a `Redis` object with that node's host and port, and use the `Redis` object to do the work. +- Instead of host and port, you can also call `Redis RedisCluster::redis(const StringView &hash_tag)` to create a `Redis` object with a hash-tag specifying the node. In this case, the returned `Redis` object creates a new connection to Redis server. **NOTE**: the returned `Redis` object, **IS NOT THREAD SAFE!**. Also, when using the returned `Redis` object, if it throws exception, you need to destroy it, and create a new one with the `RedisCluster::redis` method. + +Also you can use the [hash tags](https://redis.io/topics/cluster-spec#keys-hash-tags) to send multiple-key commands. + +See the [example section](#examples-2) for details. + +##### Publish/Subscribe + +You can publish and subscribe messages with `RedisCluster`. The interfaces are exactly the same as `Redis`, i.e. use `RedisCluster::publish` to publish messages, and use `RedisCluster::subscriber` to create a subscriber to consume messages. See [Publish/Subscribe section](#publishsubscribe) for details. + +##### Pipeline and Transaction + +You can also create `Pipeline` and `Transaction` objects with `RedisCluster`, but the interfaces are different from `Redis`. Since all commands in the pipeline and transaction should be sent to a single node in a single connection, we need to tell `RedisCluster` with which node the pipeline or transaction should be created. + +Instead of specifying the node's IP and port, `RedisCluster`'s pipeline and transaction interfaces allow you to specify the node with a *hash tag*. `RedisCluster` will calculate the slot number with the given *hash tag*, and create a pipeline or transaction with the node holding the slot. + +```C++ +Pipeline RedisCluster::pipeline(const StringView &hash_tag, bool new_connection = true); + +Transaction RedisCluster::transaction(const StringView &hash_tag, bool piped = false, bool new_connection = true); +``` + +With the created `Pipeline` or `Transaction` object, you can send commands with keys located on the same node as the given *hash_tag*. See [Examples section](#examples-2) for an example. + +**NOTE**: By default, `Pipeline` and `Transaction` will be created with a new connection. In order to avoid creating new connection, you can pass `false` as the last parameter. However, in this case, you MUST be very careful, otherwise, you might get bad performance or even dead lock. Please carefully check the related [pipeline section](#very-important-notes) before using this feature. + +#### Examples + +```C++ +#include + +using namespace sw::redis; + +auto redis_cluster = RedisCluster("tcp://127.0.0.1:7000"); + +redis_cluster.set("key", "value"); +auto val = redis_cluster.get("key"); +if (val) { + std::cout << *val << std::endl; +} + +// With hash-tag. +redis_cluster.set("key{tag}1", "val1"); +redis_cluster.set("key{tag}2", "val2"); +redis_cluster.set("key{tag}3", "val3"); +std::vector hash_tag_res; +redis_cluster.mget({"key{tag}1", "key{tag}2", "key{tag}3"}, + std::back_inserter(hash_tag_res)); + +redis_cluster.lpush("list", {"1", "2", "3"}); +std::vector list; +redis_cluster.lrange("list", 0, -1, std::back_inserter(list)); + +// Pipeline. +auto pipe = redis_cluster.pipeline("counter"); +auto replies = pipe.incr("{counter}:1").incr("{counter}:2").exec(); + +// Transaction. +auto tx = redis_cluster.transaction("key"); +replies = tx.incr("key").get("key").exec(); + +// Create a Redis object with hash-tag. +// It connects to the Redis instance that holds the given key, i.e. hash-tag. +auto r = redis_cluster.redis("hash-tag"); + +// And send command without key parameter to the server. +r.command("client", "setname", "connection-name"); +``` + +**NOTE**: By default, when you use `RedisCluster::redis(const StringView &hash_tag, bool new_connection = true)` to create a `Redis` object, instead of picking a connection from the underlying connection pool, it creates a new connection to the corresponding Redis server. So this is NOT a cheap operation, and you should try to reuse this newly created `Redis` object as much as possible. If you pass `false` as the second parameter, you can create a `Redis` object without creating a new connection. However, in this case, you should be very careful, otherwise, you might get bad performance or even dead lock. Please carefully check the related [pipeline section](#very-important-notes) before using this feature. + +```C++ +// This is BAD! It's very inefficient. +// NEVER DO IT!!! +// After sending PING command, the newly created Redis object will be destroied. +cluster.redis("key").ping(); + +// Then it creates a connection to Redis, and closes the connection after sending the command. +cluster.redis("key").command("client", "setname", "hello"); + +// Instead you should reuse the Redis object. +// This is GOOD! +auto redis = cluster.redis("key"); + +redis.ping(); +redis.command("client", "setname", "hello"); + +// This is GOOD! Create `Redis` object without creating a new connection. Use it, and destroy it ASAP. +cluster.redis("key", false).ping(); +``` + +#### Details + +`RedisCluster` maintains the newest slot-node mapping, and sends command directly to the right node. Normally it works as fast as `Redis`. If the cluster reshards, `RedisCluster` will follow the redirection, and it will finally update the slot-node mapping. It can correctly handle the following resharding cases: + +- Data migration between exist nodes. +- Add new node to the cluster. +- Remove node from the cluster. + +`redis-plus-plus` is able to handle both [MOVED](https://redis.io/topics/cluster-spec#moved-redirection) and [ASK](https://redis.io/topics/cluster-spec#ask-redirection) redirections, so it's a complete Redis Cluster client. + +If master is down, the cluster will promote one of its replicas to be the new master. *redis-plus-plus* can also handle this case: + +- When the master is down, *redis-plus-plus* losts connection to it. In this case, if you try to send commands to this master, *redis-plus-plus* will try to update slot-node mapping from other nodes. If the mapping remains unchanged, i.e. new master hasn't been elected yet, it fails to send command to Redis Cluster and throws exception. +- When the new master has been elected, the slot-node mapping will be updated by the cluster. In this case, if you send commands to the cluster, *redis-plus-plus* can get an update-to-date mapping, and sends commands to the new master. + +### Redis Sentinel + +[Redis Sentinel provides high availability for Redis](https://redis.io/topics/sentinel). If Redis master is down, Redis Sentinels will elect a new master from slaves, i.e. failover. Besides, Redis Sentinel can also act like a configuration provider for clients, and clients can query master or slave address from Redis Sentinel. So that if a failover occurs, clients can ask the new master address from Redis Sentinel. + +*redis-plus-plus* supports getting Redis master or slave's IP and port from Redis Sentinel. In order to use this feature, you only need to initialize `Redis` object with Redis Sentinel info, which is composed with 3 parts: `std::shared_ptr`, master name and role (master or slave). + +Before using Redis Sentinel with *redis-plus-plus*, ensure that you have read Redis Sentinel's [doc](https://redis.io/topics/sentinel). + +#### Sentinel + +You can create a `std::shared_ptr` object with `SentinelOptions`. + +```C++ +SentinelOptions sentinel_opts; +sentinel_opts.nodes = {{"127.0.0.1", 9000}, + {"127.0.0.1", 9001}, + {"127.0.0.1", 9002}}; // Required. List of Redis Sentinel nodes. + +// Optional. Timeout before we successfully connect to Redis Sentinel. +// By default, the timeout is 100ms. +sentinel_opts.connect_timeout = std::chrono::milliseconds(200); + +// Optional. Timeout before we successfully send request to or receive response from Redis Sentinel. +// By default, the timeout is 100ms. +sentinel_opts.socket_timeout = std::chrono::milliseconds(200); + +auto sentinel = std::make_shared(sentinel_opts); +``` + +`SentinelOptions::connect_timeout` and `SentinelOptions::socket_timeout` CANNOT be 0ms, i.e. no timeout and block forever. Otherwise, *redis-plus-plus* will throw an exception. + +See [SentinelOptions](https://github.com/sewenew/redis-plus-plus/blob/master/src/sw/redis%2B%2B/sentinel.h#L33) for more options. + +#### Role + +Besides `std::shared_ptr` and master name, you also need to specify a role. There are two roles: `Role::MASTER`, and `Role::SLAVE`. + +With `Role::MASTER`, *redis-plus-plus* will always connect to current master instance, even if a failover occurs. Each time when *redis-plus-plus* needs to create a new connection to master, or a connection is broken, and it needs to reconnect to master, *redis-plus-plus* will ask master address from Redis Sentinel, and connects to current master. If a failover occurs, *redis-plus-plus* can automatically get the address of the new master, and refresh all connections in the underlying connection pool. + +Similarly, with `Role::SLAVE`, *redis-plus-plus* will always connect to a slave instance. A master might have several slaves, *redis-plus-plus* will randomly pick one, and connect to it, i.e. all connections in the underlying connection pool, connect to the same slave instance (check [this discussion](https://github.com/sewenew/redis-plus-plus/issues/99) on why *redis-plus-plus* not connect to all slaves). If the connection is broken, while this slave instance is still an alive slave, *redis-plus-plus* will reconnect to this slave. However, if this slave instance is down, or it has been promoted to be the master, *redis-plus-plus* will randomly connect to another slave. If there's no slave alive, it throws an exception. + +#### Create Redis With Sentinel + +When creating a `Redis` object with sentinel, besides the sentinel info, you should also provide `ConnectionOptions` and `ConnectionPoolOptions`. These two options are used to connect to Redis instance. `ConnectionPoolOptions` is optional, if not specified, it creates a single connection the instance. + +```C++ +ConnectionOptions connection_opts; +connection_opts.password = "auth"; // Optional. No password by default. +connection_opts.connect_timeout = std::chrono::milliseconds(100); // Required. +connection_opts.socket_timeout = std::chrono::milliseconds(100); // Required. + +ConnectionPoolOptions pool_opts; +pool_opts.size = 3; // Optional. The default size is 1. + +auto redis = Redis(sentinel, "master_name", Role::MASTER, connection_opts, pool_opts); +``` + +You might have noticed that we didn't specify the `host` and `port` fields for `ConnectionOptions`. Because, `Redis` will get these info from Redis Sentinel. Also, in this case, `ConnectionOptions::connect_timeout` and `ConnectionOptions::socket_timeout` CANNOT be 0ms, otherwise, it throws an exception. So you always need to specify these two timeouts manually. + +After creating the `Redis` object with sentinel, you can send commands with it, just like an ordinary `Redis` object. + +If you want to write to master, and scale read with slaves. You can use the following pattern: + +```C++ +auto sentinel = std::make_shared(sentinel_opts); + +auto master = Redis(sentinel, "master_name", Role::MASTER, connection_opts, pool_opts); + +auto slave = Redis(sentinel, "master_name", Role::SLAVE, connection_opts, pool_opts); + +// Write to master. +master.set("key", "value"); + +// Read from slave. +slave.get("key"); +``` + +### Redis Stream + +Since Redis 5.0, it introduces a new data type: *Redis Stream*. *redis-plus-plus* has built-in methods for all stream commands except the *XINFO* command (of course, you can use the [Generic Command Interface](#generic-command-interface) to send *XINFO* command). + +However, the replies of some streams commands, i.e. *XPENDING*, *XREAD*, are complex. So I'll give some examples to show you how to work with these built-in methods. + +#### Examples + +```C++ +auto redis = Redis("tcp://127.0.0.1"); + +using Attrs = std::vector>; + +// You can also use std::unordered_map, if you don't care the order of attributes: +// using Attrs = std::unordered_map; + +Attrs attrs = { {"f1", "v1"}, {"f2", "v2"} }; + +// Add an item into the stream. This method returns the auto generated id. +auto id = redis.xadd("key", "*", attrs.begin(), attrs.end()); + +// Each item is assigned with an id: pair>. +// NOTE: the attribute part might be nil reply, check [this issue](https://github.com/sewenew/redis-plus-plus/issues/283) for detail. +using Item = std::pair>; +using ItemStream = std::vector; + +// If you don't care the order of items in the stream, you can also use unordered_map: +// using ItemStream = std::unordered_map; + +// Read items from a stream, and return at most 10 items. +// You need to specify a key and an id (timestamp + offset). +std::unordered_map result; +redis.xread("key", id, 10, std::inserter(result, result.end())); + +// Read from multiple streams. For each stream, you need to specify a key and an id. +std::unordered_map keys = { {"key", id}, {"another-key", "0-0"} }; +redis.xread(keys.begin(), keys.end(), 10, std::inserter(result, result.end())); + +// Block for at most 1 second if currently there's no data in the stream. +redis.xread("key", id, std::chrono::seconds(1), 10, std::inserter(result, result.end())); + +// Block for multiple streams. +redis.xread(keys.begin(), keys.end(), std::chrono::seconds(1), 10, std::inserter(result, result.end())); + +// Read items in a range: +ItemStream item_stream; +redis.xrange("key", "-", "+", std::back_inserter(item_stream)); + +// Trim the stream to a given number of items. After the operation, the stream length is NOT exactly +// 10. Instead, it might be much larger than 10. +// `XTRIM key MAXLEN 10` +redis.xtrim("key", 10); + +// In order to trim the stream to exactly 10 items, specify the third argument, i.e. approx, as false. +// `XTRIM key MAXLEN ~ 10` +redis.xtrim("key", 10, false); + +// Delete an item from the stream. +redis.xdel("key", id); + +// Create a consumer group. +redis.xgroup_create("key", "group", "$"); + +// If the stream doesn't exist, you can set the fourth argument, i.e. MKSTREAM, to be true. +// redis.xgroup_create("key", "group", "$", true); + +id = redis.xadd("key", "*", attrs.begin(), attrs.end()); + +// Read item by a consumer of a consumer group. +redis.xreadgroup("group", "consumer", "key", ">", 1, std::inserter(result, result.end())); + +using PendingItem = std::tuple; +std::vector pending_items; + +// Get pending items of a speicified consumer. +redis.xpending("key", "group", "-", "+", 1, "consumer", std::back_inserter(pending_items)); + +redis.xack("key", "group", id); + +redis.xgroup_delconsumer("key", "group", "consumer"); +redis.xgroup_destroy("key", "group"); +``` + +If you have any problem on sending stream commands to Redis, please feel free to let me know. + +### Redis Modules + +[Redis Modules](https://redis.io/modules) enrich Redis. However, *redis-plus-plus* does not have built-in support/method for these modules, although you can use the [generic interface](#generic-command-interface) to send commands related to these modules. + +Fortunately, [@wingunder](https://github.com/wingunder) did a great job to make the work easier. He wrote [redis-plus-plus-modules](https://github.com/wingunder/redis-plus-plus-modules), which is a header only project that has built-in support for some popular modules. If you need to work with Redis Modules, you should have a try. + +@wingunder also contributes a lot to *redis-plus-plus*. Many thanks to @wingunder! + +### Async Interface + +*redis-plus-plus* also supports async interface, however, async support for Transaction and Subscriber is still on the way. + +The async interface depends on third-party event library, and so far, only libuv is supported. + +#### Installation + +You must install *libuv*(e.g. *apt-get install libuv1-dev*) before install *hiredis* and *redis-plus-plus*. + +*hiredis* v1.0.0's async interface is different from older version, and *redis-plus-plus* only supports *hiredis* v1.0.0 or later. So you need to ensure you've installed the right version of hiredis before installing *redis-plus-plus*. Also, you should NEVER install multiple versions of *hiredis*, otherwise, you'll get some wired problems. If you already installed an older version, remove it, and install a newer version. + +When installing *redis-plus-plus*, you should specify the following command line option: `-DREDIS_PLUS_PLUS_BUILD_ASYNC=libuv`. + +``` +cmake -DCMAKE_PREFIX_PATH=/installation/path/to/libuv/and/hiredis -DREDIS_PLUS_PLUS_BUILD_ASYNC=libuv .. + +make + +make install +``` + +#### Getting Started + +The async interface is similar to sync interface, except that you should include *sw/redis++/async_redis++.h*, and define an object of `sw::redis::AsyncRedis`, and the related methods return `Future` object (so far, only `std::future` and `boost::future` are supported, support for other implementations of *future* is on the way). + +**NOTE**: When building your application code, don't forget to link libuv. + +``` +#include + +ConnectionOptions opts; +opts.host = "127.0.0.1"; +opts.port = 6379; + +ConnectionPoolOptions pool_opts; +pool_opts.size = 3; + +auto async_redis = AsyncRedis(opts, pool_opts); + +Future ping_res = async_redis.ping(); + +Future set_res = async_redis.set("key", "val"); + +Future> get_res = async_redis.get("key"); + +unordered_map m = {{"a", "b"}, {"c", "d"}}; +Future hmset_res = async_redis.hmset("hash", m.begin(), m.end()); + +auto hgetall_res = async_redis.hgetall>("hash"); + +cout << ping_res.get() << endl; +cout << set_res.get() << endl; +auto val = get_res.get(); +if (val) + cout << *val << endl; +else + cout << "not exist" << endl; + +hmset_res.get(); + +for (const auto &ele : hgetall_res.get()) + cout << ele << endl; + +// Generic interface. + +// There's no *AsyncRedis::client_getname* interface. +// But you can use *Redis::command* to get the client name. +auto getname_res = redis.command("client", "getname"); +val = getname_res.get(); +if (val) { + std::cout << *val << std::endl; +} +``` + +#### Redis Sentinel + +Aysnc interface also supports Redis Sentinel. + +``` +#include + +SentinelOptions sentinel_opts; +sentinel_opts.nodes = { + {"127.0.0.1", 8000}, + {"127.0.0.1", 8001}, + {"127.0.0.1", 8002} +}; + +sentinel_opts.connect_timeout = std::chrono::milliseconds(100); +sentinel_opts.socket_timeout = std::chrono::milliseconds(100); + +auto sentinel = std::make_shared(sentinel_opts); + +onnectionOptions connection_opts; +connection_opts.connect_timeout = std::chrono::milliseconds(100); // Required. +connection_opts.socket_timeout = std::chrono::milliseconds(100); // Required. + +ConnectionPoolOptions pool_opts; +pool_opts.size = 3; // Optional. The default size is 1. + +// Connect to master node. +AsyncRedis redis(sentinel, "mymaster", Role::MASTER, connection_opts, pool_opts); + +// The following code randomly connects to one of the slave nodes. +// AsyncRedis redis(sentinel, "mymaster", Role::SLAVE, connection_opts, pool_opts); + +redis.set("key", "value"); + +auto value = redis.get("key").get(); +``` + +The async support for sentinel is similar with the sync one, except that you need to create an `AsyncSentinel` object instead of a `Sentinel` object. Check [Redis Sentinel](#redis-sentinel) for more details on `SentinelOptions`, `ConnectionOptions` and `Role`. + +#### Redis Cluster + +Aysnc interface also supports Redis Cluster. Instead of `AsyncRedis`, you need to create an `AsyncRedisCluster` object. + +``` +ConnectionOptions opts; +opts.host = "127.0.0.1"; +opts.port = 6379; + +ConnectionPoolOptions pool_opts; +pool_opts.size = 3; + +auto async_cluster = AsyncRedisCluster(opts, pool_opts); + +Future set_res = async_cluster.set("key", "val"); + +Future> get_res = async_cluster.get("key"); + +auto mget_res = async_cluster.mget>({"{hashtag}key1", "{hashhag}key2", "{hashtag}key3"}); + +unordered_map m = {{"a", "b"}, {"c", "d"}}; +Future hmset_res = async_redis.hmset("hash", m.begin(), m.end()); +``` + +#### Event Loop + +By default, `AsyncRedis` and `AsyncRedisCluster` create a default event loop, and runs the loop in a dedicated thread to handle read and write operations. However, you can also share the underlying event loop with multiple `AsyncRedis` and `AsyncRedisCluster` objects. In order to do that, you need to create a `std::shared_ptr`, and pass it to the constructors of `AsyncRedis` and `AsyncRedisCluster`. + +``` +auto event_loop = std::make_shared(); + +auto redis = AsyncRedis(connection_opts, pool_opts, loop); + +auto cluster = AsyncRedisCluster(connection_opts, pool_opts, Role::MASTER, loop); +``` + +#### Future with Continuation + +Unfortunately, `std::future` doesn't support [continuation](https://en.cppreference.com/w/cpp/experimental/future/then) so far, which is inconvenient. However, some other libraries, e.g. boost and folly, have continuation support. + +By default, *redis-plus-plus* returns `std::future` for async interface. However, you can also make it return `boost::future` by specifying `-DREDIS_PLUS_PLUS_ASYNC_FUTURE=boost` when running cmake (`folly` and other libraries might be supported in the future). Of course, in this case, you need to install boost first. + +``` +cmake -DREDIS_PLUS_PLUS_BUILD_ASYNC=libuv -DREDIS_PLUS_PLUS_ASYNC_FUTURE=boost .. +``` + +**NOTE**: When building your application code, don't forget to link boost related libs, e.g. -lboost_thread, -lboost_system. + +Then you can take advantage of `boost::future`'s continuation support: + +``` +#include + +ConnectionOptions opts; +opts.host = "127.0.0.1"; +opts.port = 6379; +auto redis = AsyncRedis(opts); +auto fut = redis.get("key").then([](sw::redis::Future> fut) { + auto val = fut.get(); + if (val) cout << *val << endl; + }); +// Do other things + +// Wait for the continuation finishes. +fut.get(); +``` + +You can also use a thread pool to run the continuation: + +``` +#define BOOST_THREAD_PROVIDES_EXECUTORS + +// You might also need to `#define BOOST_THREAD_USES_MOVE` with some version of Boost. +// See [this issue](https://github.com/sewenew/redis-plus-plus/issues/272) for detail. + +#include +#include + +boost::executors::basic_thread_pool pool(3); +auto fut = redis.get("key").then(pool, + [](sw::redis::Future> fut) { + auto val = fut.get(); + if (val) cout << *val << endl; + }); + +// Do other things + +fut.get(); +``` + +## Redis Recipes + +We can create many interesting data structures and algorithms based on Redis, such as [Redlock](https://redis.io/topics/distlock). We call these data structures and algorithms as **Redis Recipes**. *redis-plus-plus* will support some of these recipes. + +**NOTE**: These recipes will be first implemented on the [recipes branch](https://github.com/sewenew/redis-plus-plus/tree/recipes). I'd like to hear your feedback on the API of these recipes, and when these APIs become stable, I'll merge the code into the master branch. So APIs on the *recipes* branch are NOT stable, and might be changed in the future. + +### Redlock + +[Redlock](https://redis.io/topics/distlock) is a distributed lock based on Redis. Thanks to @wingunder's [suggestion](https://github.com/sewenew/redis-plus-plus/issues/24), *redis-plus-plus* supports Redlock now. @wingunder and I made two different implementation of Redlock: one based on Lua script, and the other based on transaction. The Lua script version should be faster, and also it has many other parameters to control the behavior. However, if you are not allowed to, or don't want to run Lua scripts inside Redis, you could try using the transaction version. + +#### Examples + +``` +auto redis1 = Redis("tcp://127.0.0.1:7000"); +auto redis2 = Redis("tcp://127.0.0.1:7001"); +auto redis3 = Redis("tcp://127.0.0.1:7002"); + +// Lua script version: +{ + RedLockMutex mtx({redis1, redis2, redis3}, "resource"); + + // Not locked. + RedLock lock(mtx, std::defer_lock); + + // Try to get the lock, and keep 30 seconds. + // It returns the validity time of the lock, i.e. the lock is only + // valid in *validity_time*, after that the lock might be acquired by others. + // If failed to acquire the lock, throw an exception of Error type. + auto validity_time = lock.try_lock(std::chrono::seconds(30)); + + // Extend the lock before the lock expired. + validity_time = lock.extend_lock(std::chrono::seconds(10)); + + // You can unlock explicitly. + lock.unlock(); +} // If unlock() is not called, the lock will be unlocked automatically when it's destroied. + +// Transaction version: +{ + RedMutex mtx({redis1, redis2, redis3}, "resource"); + + RedLock lock(mtx, std::defer_lock); + auto validity_time = lock.try_lock(std::chrono::seconds(30)); + validity_time = lock.extend_lock(std::chrono::seconds(30)); + + // You can unlock explicitly. + lock.unlock(); +} +``` + +Please refer to the [code](https://github.com/sewenew/redis-plus-plus/blob/recipes/src/sw/redis%2B%2B/recipes/redlock.h) for detail.

If you see something wrong here, please file a bug and explain, in +simple words, what needs changing and why. + + +Quick start +----------- + +If you just want to get it built and installed quickly, run `cmake` from the +root of the libpqxx source tree.

Configure +2. Compile +3. Test +4. Install +5. Use + +The Test step is optional. + + +Configure +--------- + +Run `cmake` to configure your build. It figures out various parameters, such +as where libpq and its headers are, which C++ features your compiler supports, +and which options your compiler needs. CMake generates configuration for your +build tool: `Makefile`s for `make`, or a Solution (".sln") file for MSVC's +`msbuild`, and so on. + +At this stage you can also override those options yourself. e.g. to instruct +the compiler to look for libpq in a non-standard place, or to use a different +compiler, or pass different compiler flags. Don't try to specify those while +doing the actual compile; set them once when running `cmake`. + +Let's say `$BUILD` is the directory where you want to build libpqxx, and +`$SRC` is where its source code is. So for example, the readme file will be at +`$SRC/README.md`. + +In the simplest case, you just do: + +```shell + cd $BUILD + cmake $SRC +``` + +Add CMake options as needed. There's more about the options below. I'll also +explain the two directories. + + +### Cheat sheet + +Here are some popular `cmake` options for libpqxx: +* `-DSKIP_BUILD_TEST=on` skips compiling libpqxx's tests. +* `-DBUILD_SHARED_LIBS=on` to build a shared library. +* `-DBUILD_SHARED_LIBS=off` to build a static library. +* `-DBUILD_DOC=on` to build documentation. +* `-DINSTALL_TEST=on` to install test executor binary. + +On Windows, I recommend building libpqxx as a shared library and bundling it +with your application. On other platforms I would prefer a static library. + +Building the documentation requires some tools to be installed. It takes at +least Doxygen, but there's no list of requirements. The way to get this set up +is to just try it and see what it's missing. + + +### Generators + +You can also choose your own build tool by telling CMake to use a particular +"generator." For example, here's how to force use of `make`: + +```shell + cmake -G 'Unix Makefiles' +``` + +Or if you prefer to build using `ninja` instead: + +```shell + cmake -G Ninja +``` + +There are many more options. You may prefer yet a different build tool. + + +### Finding libpq + +The CMake step tries to figure out where libpq is, using Cmake's `find_package` +function. If that doesn't work, or if you want a libpq in a different location +from the one it finds, there are two ways to override it. + +The first is to set the individual include and link paths. + +To make the build look for the libpq headers in some directory `$DIR`, add +these options: +* `-DPostgreSQL_TYPE_INCLUDE_DIR=$DIR` +* `-DPostgreSQL_INCLUDE_DIR=$DIR` + +To make the build look for the libpq library binary in a directory `$DIR`, add +this option: +* `-DPostgreSQL_LIBRARY_DIR=$DIR` + +The second, easier way requires CMake 3.12 or better. Here, you specify a path +to a full PostgreSQL build tree. You do this (again for some directory `$DIR`) +by simply passing this cmake option: `-DPostgreSQL_ROOT=$DIR` + + +### Source and Build trees + +Where should you run `cmake`? + +Two directories matter when building libpqxx: the _source tree_ (where the +libpqxx source code is) and the _build tree_ (where you want your build +artefacts). Here I will call them `$SRC` and `$BUILD`, but you can call them +anything you like. + +They can be one and the same, if you like. It's convenient, but less clean, as +source code and build artefacts will exist in the same directory tree. If +you're going to delete the source tree after installing, of course it's fine to +make a mess in there. + + +Compile +------- + +To compile, run: + +```shell + cmake --build $BUILD +``` + +(Where `$BUILD` is again the directory where you wish to do the build.) + +This command will invoke your build tool. Other ways to do the same thing +would be... +* With Unix Makefiles: `make` +* With Ninja: `ninja` +* With Visual Studio: `msbuild libpqxx.sln` +* etc. + +Depending on your build tool, you may want to speed this up by adding an option +like `-j 16`, where `16` is an example of how many processes you might want to +run in parallel. The optimal number depends on your available CPUs and memory. +If you have enough memory, usually the number of CPUs will be a good starting +point for the right number. Don't use this option with Ninja though. It +figures things out for itself. + + +Test +---- + +Of course libpqxx comes with a test suite, to check that the library is +functioning correctly. + +You can run it, but there's one caveat: you need to give it a database where it +can log in, without a password or any other parameters, and try out various +things. + +And when I say you need to "give" it a database, I really mean "give." The +test suite will create and drop tables. Those will all have names prefixed +with "pqxx", so it's probably safe to use a database you already had, but if +any of the items in your database happen to have names starting with `pqxx`, +tough luck. They're fair game. + +Enter this in your shell to build and run the tests: + +```shell + test/runner +``` + + +### Configuring the test database + +But what if you do need a password to log into your test database? Or, what if +it's running on a different system so you need to pass that machine's address? +What if it's not running on the default port? + +You can set these parameters for the test suite, or for any other libpq-based +application, using the following environment variables. (They only set default +values, so they won't override parameters that the application sets in some +other way.) +* `PGHOST` — the IP address where we can contact the database's socket. Or + for a Unix domain socket, its absolute path on the filesystem. +* `PGPORT` — TCP port number on which we can connect to the database. +* `PGDATABASE` — the name of the database to which you wish to connect. +* `PGUSER` — user name under which you wish to log in on the database. +* `PGPASSWORD` — user name's password for accessing the database. + +See the full list at https://www.postgresql.org/docs/current/libpq-envars.html + +**Be careful with passwords,** by the way. Depending on your operating system +and configuration, an attacker with access to your machine could try to read +your password if you set it on the command line: +* Your shell may keep a log of the commands you have entered. +* Environment variables may be visible to other users on the system. + +If at all possible, rely on postgres "peer authentication." Once set up, it is +both more secure and more convenient than passwords. + + +Install +------- + +Once you've built libpqxx, CMake can also help you install the library and +headers on your system. The default installation location will vary from one +operating system to another, but you can set it explicitly. + +Let's say you've got your finished build in `$BUILD`, and you want to install +it to your system's default install location.

It has three ways of finding those: +1. Asking a popular tool called `pkg-config`, if installed. +2. Asking postgres' deprecated `pg_config` tool, if installed. +3. Through explicit command-line options to `configure`. + +The explicit command-line options are `--with-postgres-lib` (for the libpq +library binary) and `--with-postgres-include` (for the libpq headers). + +If you want to use a version of libpq that's not installed in a standard +location, e.g. if you're cross-compiling to produce a binary for a different +CPU architecture than your native system's, use the explicit options. + + +### Where does the `configure` script come from? + +I didn't write the `configure` script. It was generated by GNU `autoconf` and +related GNU tools. There's a script to re-generate it, called `autogen.sh`. + +The contents of `configure` are based on a higher-level script called +`configure.ac`. This is where I script checks for specific features in libpq +or the compiler. The `configure` script adds a lot of built-in items that I +don't need to worry about, such as figuring out exactly how your build tools +work. + +Don't try to debug `configure` yourself if you can help it. It's very hard to +read, partly because it's automatically generated, but also because it is +engineered to work with an extremely broad range of shells, compilers, tools, +and operating systems. If you're going to do a "deep dive," try looking at +`configure.ac` instead. + + +### Source and Build trees + +Where should you run `configure`? + +Two directories matter when building libpqxx: the _source tree_ (where the +libpqxx source code is) and the _build tree_ (where you want your build +artefacts). Here I will call them `$SRC` and `$BUILD`, but you can call them +anything you like. + +They can be one and the same, if you like. It's convenient, but less clean, as +source code and build artefacts will exist in the same directory tree. If +you're going to delete the source tree after installing, of course it's fine to +make a mess in there. + + +Compile +------- + +To start the compile, run the `make` tool. It will go through all the steps to +produce a libpqxx library binary. + +Beware though, it only runs _one_ compiler process at a time. That could take +a while. Use the `-j` option to make it run concurrent processes, e.g.: + +```shell + make -j8 +``` + +Very roughly speaking, it's probably fastest if you run one process per CPU +core in your system. If you have the `nproc` utility installed: + +```shell + make -j$(nproc) +``` + +If you want a very fast build and don't mind missing out on efficient code or +documentation, tweak the Configure step above by adding `configure` options +like `CXXFLAGS=-O0` and `--disable-documentation`. + + +Test +---- + +Of course libpqxx comes with a test suite, to check that the library is +functioning correctly. + +You can run it, but there's one caveat: you need to give it a database where it +can log in, without a password or any other parameters, and try out various +things. + +And when I say you need to "give" it a database, I really mean "give."

Or, use the +`configure` script's `--prefix` option to set an install location. + +(If you want to see exactly what happens, you can run any `make` command line +with the `-n` option, which means: don't actually do this, but print all the +commands you would execute if you did. It's a lot of output though.) + +To install, ensure that you have sufficient privileges to write the files to +their install locations, and run: + +```shell + make install +``` + +Save your build tree somewhere, so that you will be able to undo installation +in the future: + +```shell + make uninstall +``` + +When using the library, make sure the libpqxx headers are in your compiler's +include path.

The library builds on top of +PostgreSQL's standard C API, libpq, though your code won't notice. + +If you're getting the code straight from the Git repo, the head of the `master` +branch represents the current _development version._ Releases are tags on +commits in `master`. For example, to get version 7.1.1: + + git checkout 7.1.1 + + +Upgrade notes +------------- + +**The 7.x versions require at least C++17.** Make sure your compiler is up to +date. For libpqxx 8.x you will need at least C++20. + +Also, **7.0 makes some breaking changes in rarely used APIs:** +* There is just a single `connection` class. It connects immediately. +* Custom `connection` classes are no longer supported. +* It's no longer possible to reactivate a connection once it's been closed. +* The API for defining string conversions has changed. + +If you're defining your own type conversions, **7.1 requires one additional +field in your `nullness` traits.** + + +Building libpqxx +---------------- + +There are two different ways of building libpqxx from the command line: +1. Using CMake, on any system which supports it. +2. On Unix-like systems, using a `configure` script. + +"Unix-like" systems include GNU/Linux, Apple macOS and the BSD family, AIX, +HP-UX, Irix, Solaris, etc. Even on Microsoft Windows, a Unix-like environment +such as WSL, Cygwin, or MinGW should work. + +You'll find detailed build and install instructions in `BUILDING-configure.md` +and `BUILDING-cmake.md`, respectively. + +And if you're working with Microsoft Visual Studio, have a look at Gordon +Elliott's +[ + Easy-PQXX Build for Windows Visual Studio +](https://github.com/GordonLElliott/Easy-PQXX-Build-for-Windows-Visual-Studio) +project. + + +Documentation +------------- + +Building the library, if you have the right tools installed, generates HTML +documentation in the `doc/` directory. It is based on the headers in +`include/pqxx/` and text in `include/pqxx/doc/`. This documentation is also +available online at [readthedocs](https://libpqxx.readthedocs.io). + + +Programming with libpqxx +------------------------ + +Your first program will involve the libpqxx classes `connection` (see the +`pqxx/connection.hxx` header), and `work` (a convenience alias for +`transaction<>` which conforms to the interface defined in +`pqxx/transaction_base.hxx`). + +These `*.hxx` headers are not the ones you include in your program. Instead, +include the versions without filename suffix (e.g. `pqxx/connection`). Those +will include the actual .hxx files for you. This was done so that includes are +in standard C++ style (as in `` etc.), but an editor will still +recognize them as files containing C++ code. + +Continuing the list of classes, you will most likely also need the result class +(`pqxx/result.hxx`). In a nutshell, you create a `connection` based on a +Postgres connection string (see below), create a `work` in the context of that +connection, and run one or more queries on the work which return `result` +objects. The results are containers of rows of data, each of which you can +treat as an array of strings: one for each field in the row. It's that simple. + +Here is a simple example program to get you going, with full error handling: + +```c++ + #include + #include + + int main() + { + try + { + // Connect to the database. + pqxx::connection C; + std::cout << "Connected to " << C.dbname() << '\n'; + + // Start a transaction. + pqxx::work W{C}; + + // Perform a query and retrieve all results. + pqxx::result R{W.exec("SELECT name FROM employee")}; + + // Iterate over results. + std::cout << "Found " << R.size() << "employees:\n"; + for (auto row: R) + std::cout << row[0].c_str() << '\n'; + + // Perform a query and check that it returns no result. + std::cout << "Doubling all employees' salaries...\n"; + W.exec0("UPDATE employee SET salary = salary*2"); + + // Commit the transaction. + std::cout << "Making changes definite: "; + W.commit(); + std::cout << "OK.\n"; + } + catch (std::exception const &e) + { + std::cerr << e.what() << '\n'; + return 1; + } + return 0; + } +``` + + +Connection strings +------------------ + +Postgres connection strings state which database server you wish to connect to, +under which username, using which password, and so on. Their format is defined +in the documentation for libpq, the C client interface for PostgreSQL. +Alternatively, these values may be defined by setting certain environment +variables as documented in e.g. the manual for psql, the command line interface +to PostgreSQL. Again the definitions are the same for libpqxx-based programs. + +The connection strings and variables are not fully and definitively documented +here; this document will tell you just enough to get going. Check the +PostgreSQL documentation for authoritative information. + +The connection string consists of attribute=value pairs separated by spaces, +e.g. "user=john password=1x2y3z4". The valid attributes include: +* `host` — + Name of server to connect to, or the full file path (beginning with a + slash) to a Unix-domain socket on the local machine. Defaults to + "/tmp". Equivalent to (but overrides) environment variable PGHOST. +* `hostaddr` — + IP address of a server to connect to; mutually exclusive with "host". +* `port` — + Port number at the server host to connect to, or socket file name + extension for Unix-domain connections. Equivalent to (but overrides) + environment variable PGPORT. +* `dbname` — + Name of the database to connect to. A single server may host multiple + databases. Defaults to the same name as the current user's name. + Equivalent to (but overrides) environment variable PGDATABASE. +* `user` — + User name to connect under. This defaults to the name of the current + user, although PostgreSQL users are not necessarily the same thing as + system users. +* `requiressl` — + If set to 1, demands an encrypted SSL connection (and fails if no SSL + connection can be created). + +Settings in the connection strings override the environment variables, which in +turn override the default, on a variable-by-variable basis. You only need to +define those variables that require non-default values. + + +Linking with libpqxx +-------------------- + +To link your final program, make sure you link to both the C-level libpq library +and the actual C++ library, libpqxx. With most Unix-style compilers, you'd do +this using the options + + -lpqxx -lpq + +while linking. Both libraries must be in your link path, so the linker knows +where to find them. Any dynamic libraries you use must also be in a place +where the loader can find them when loading your program at runtime. + +Some users have reported problems using the above syntax, however, particularly +when multiple versions of libpqxx are partially or incorrectly installed on the +system. If you get massive link errors, try removing the "-lpqxx" argument from +the command line and replacing it with the name of the libpqxx library binary +instead. That's typically libpqxx.a, but you'll have to add the path to its +location as well, e.g. /usr/local/pqxx/lib/libpqxx.a. This will ensure that the +linker will use that exact version of the library rather than one found +elsewhere on the system, and eliminate worries about the exact right version of +the library being installed with your program.. diff --git a/ext/libpqxx-7.7.3/VERSION b/ext/libpqxx-7.7.3/VERSION new file mode 100644 index 000000000..d92ba80de --- /dev/null +++ b/ext/libpqxx-7.7.3/VERSION @@ -0,0 +1 @@ +7.7.3 diff --git a/ext/libpqxx-7.7.3/aclocal.m4 b/ext/libpqxx-7.7.3/aclocal.m4 new file mode 100644 index 000000000..2c938cff6 --- /dev/null +++ b/ext/libpqxx-7.7.3/aclocal.m4 @@ -0,0 +1,1187 @@ +# generated automatically by aclocal 1.16.4 -*- Autoconf -*- + +# Copyright (C) 1996-2021 Free Software Foundation, Inc. + +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, +[m4_warning([this file was generated for autoconf 2.69. +You have another version of autoconf.

The `exec1` functions expect exactly one row of data, +so they return just a `row`, not a full `result`.) + +Result objects are an all-or-nothing affair.

At least you'd want to look up the column index before your loop +and then use numerical indexes inside the loop. + +For C++23 or better, there's also a two-dimensional array access operator: + +```cxx + for (std::size_t rownum=0u; rownum < num_rows; ++rownum) + { + for (std::size_t colnum=0u; colnum < num_cols; ++colnum) + std::cout result[rownum, colnum].c_str() << '\t'; + std::cout << '\n'; + } +``` + +And of course you can use classic "begin/end" loops: + +```cxx + for (auto row = std::begin(r); row != std::end(r); row++) + { + for (auto field = std::begin(row); field != std::end(row); field++) + std::cout << field->c_str() << '\t'; + std::cout << '\n'; + } +``` + +Result sets are immutable, so all iterators on results and rows are actually +`const_iterator`s. There are also `const_reverse_iterator` types, which +iterate backwards from `rbegin()` to `rend()` exclusive. + +All these iterator types provide one extra bit of convenience that you won't +normally find in C++ iterators: referential transparency. You don't need to +dereference them to get to the row or field they refer to. That is, instead +of `row->end()` you can also choose to say `row.end()`. Similarly, you +may prefer `field.c_str()` over `field->c_str()`. + +This becomes really helpful with the array-indexing operator. With regular +C++ iterators you would need ugly expressions like `(*row)[0]` or +`row->operator[](0)`. With the iterator types defined by the result and +row classes you can simply say `row[0]`. + + +Streaming rows +-------------- + +There's another way to go through the rows coming out of a query. It's +usually easier and faster, but there are drawbacks. + +**One,** you start getting rows before all the data has come in from the +database. That speeds things up, but what happens if you lose your network +connection while transferring the data? Your application may already have +processed some of the data before finding out that the rest isn't coming. If +that is a problem for your application, streaming may not be the right choice. + +**Two,** streaming only works for some types of query. The `stream()` function +wraps your query in a PostgreSQL `COPY` command, and `COPY` only supports a few +commands: `SELECT`, `VALUES`, `or an `INSERT`, `UPDATE`, or `DELETE` with a +`RETURNING` clause. See the `COPY` documentation here: +https://www.postgresql.org/docs/current/sql-copy.html + +**Three,** when you convert a field to a "view" type (such as +`std::string_view` or `std::basic_string_view`), the view points to +underlying data which only stays valid until you iterate to the next row or +exit the loop. So if you want to use that data for longer than a single +iteration of the streaming loop, you'll have to store it somewhere yourself. + +Now for the good news. Streaming does make it very easy to query data and loop +over it: + +```cxx + for (auto [id, name, x, y] : + tx.stream( + "SELECT id, name, x, y FROM point")) + process(id + 1, "point-" + name, x * 10.0, y * 10.0); +``` + +The conversion to C++ types (here `int`, `std::string_view`, and two `float`s) +is built into the function.

When you +include an integer value in a query, you use `to_string` to convert it to that +text format. When you get a query result field "as a float," it converts from +the text format to a floating-point type. These conversions are everywhere in +libpqxx. + +The conversion sydstem supports many built-in types, but it is also extensible. +You can "teach" libpqxx (in the scope of your own application) to convert +additional types of values to and from PostgreSQL's string format. + +This is massively useful, but it's not for the faint of heart. You'll need to +specialise some templates. And, **the API for doing this can change with any +major libpqxx release.** + + +Converting types +---------------- + +In your application, a conversion is driven entirely by a C++ type you specify. +The value's SQL type has nothing to do with it, nor is there anything in the +string that would identify its type. + +So, if you've SELECTed a 64-bit integer from the database, and you try to +convert it to a C++ "short," one of two things will happen: either the number +is small enough to fit in your `short` (and it just works), or else it throws a +conversion exception. + +Or, your database table might have a text column, but a given field may contain +a string that _looks_ just like a number. You can convert that value to an +integer type just fine. Or to a floating-point type. All that matters to the +conversion is the actual value, and the type. + +In some cases the templates for these conversions can tell the type from the +arguments you pass them: + + auto x = to_string(99); + +In other cases you may need to instantiate template explicitly: + + auto y = from_string("99"); + + +Supporting a new type +--------------------- + +Let's say you have some other SQL type which you want to be able to store in, +or retrieve from, the database. What would it take to support that? + +Sometimes you do not need _complete_ support. You might need a conversion _to_ +a string but not _from_ a string, for example. The conversion is defined at +compile time, so don't be too afraid to be incomplete. If you leave out one of +these steps, it's not going to crash at run time or mess up your data. The +worst that can happen is that your code won't build. + +So what do you need for a complete conversion? + +First off, of course, you need a C++ type. It may be your own, but it +doesn't have to be. It could be a type from a third-party library, or even one +from the standard library that libpqxx does not yet support. + +You also specialise the `pqxx::type_name` variable to specify the type's name. +This is important for all code which mentions your type in human-readable text, +such as error messages. + +Then, does your type have a built-in null value? You specialise the +`pqxx::nullness` template to specify the details. + +Finally, you specialise the `pqxx::string_traits` template. This is where you +define the actual conversions. + +Let's go through these steps one by one. + + +Your type +--------- + +You'll need a type for which the conversions are not yet defined, because the +C++ type is what determines the right conversion. One type, one set of +conversions. + +The type doesn't have to be one that you create. The conversion logic was +designed such that you can build it around any type. So you can just as +easily build a conversion for a type that's defined somewhere else. There's +no need to include any special methods or other members inside it. That's also +how libpqxx can support converting built-in types like `int`. + +By the way, if the type is an enum, you don't need to do any of this. Just +invoke the preprocessor macro `PQXX_DECLARE_ENUM_CONVERSION`, from the global +namespace near the top of your translation unit, and pass the type as an +argument. + +The library also provides specialisations for `std::optional`, +`std::shared_ptr`, and `std::unique_ptr`. If you have conversions for +`T`, you'll also have conversions for those. + + +Specialise `type_name` +---------------------- + +When errors happen during conversion, libpqxx will compose error messages for +the user. Sometimes these will include the name of the type that's being +converted. + +To tell libpqxx the name of each type, there's a template variable called +`pqxx::type_name`. For any given type `T`, it should have a specialisation +that provides that `T`'s human-readable name: + + namespace pqxx + { + template<> std::string const type_name{"T"}; + } + +(Yes, this means that you need to define something inside the pqxx namespace. +Future versions of libpqxx may move this into a separate namespace.) + +Define this early on in your translation unit, before any code that might cause +libpqxx to need the name. That way, the libpqxx code which needs to know the +type's name can see your definition. + + +Specialise `nullness` +--------------------- + +A struct template `pqxx::nullness` defines whether your type has a natural +"null value" built in. If so, it also provides member functions for producing +and recognising null values. + +The simplest scenario is also the most common: most types don't have a null +value built in. In that case, derive your nullness traits from +`pqxx::no_null`: + + namespace pqxx + { + template<> struct nullness : pqxx::no_null {}; + } + +(Here again you're defining this in the pqxx namespace.) + +If your type does have a natural null value, the definition gets a little more +complex: + + namespace pqxx + { + template<> struct nullness + { + static constexpr bool has_null{true}; + static constexpr bool always_null{false}; + + static bool is_null(T const &value) + { + // Return whether "value" is null. + return ...; + } + + [[nodiscard]] static T null() + { + // Return a null value. + return ...; + } + }; + } + +You may be wondering why there's a function to produce a null value, but also a +function to check whether a value is null. Why not just compare the value to +the result of `null()`? Because two null values may not be equal. `T` may +have several different null values. Or it may override the comparison +operator, similar to SQL where NULL is not equal to NULL. + +As a third case, your type may be one that _always_ represents a null value. +This is the case for `std::nullptr_t` and `std::nullopt_t`. In that case, you +set `nullness::always_null` to `true` (as well as `has_null` of course), +and you won't need to define any actual conversions. + + +Specialise `string_traits` +------------------------- + +This part is more work. (You can skip it for types that are _always_ null, +but those will be rare.) Specialise the `pqxx::string_traits` template: + + namespace pqxx + { + template<> struct string_traits + { + static T from_string(std::string_view text); + static zview to_buf(char *begin, char *end, T const &value); + static char *into_buf(char *begin, char *end, T const &value); + static std::size_t size_buffer(T const &value) noexcept; + }; + } + +You'll also need to write those member functions, or as many of them as needed +to get your code to build. + + +### `from_string` + +We start off simple: `from_string` parses a string as a value of `T`, and +returns that value. + +The string may not be zero-terminated; it's just the `string_view` from +beginning to end (exclusive). In your tests, cover cases where the string +does not end in a zero byte. + +It's perfectly possible that the string isn't actually a `T` value. Mistakes +happen. In that case, throw a `pqxx::conversion_error`. + +(Of course it's also possible that you run into some other error, so it's fine +to throw different exceptions as well. But when it's definitely "this is not +the right format for a `T`," throw `conversion_error`.) + + +### `to_buf` + +In this function, you convert a value of `T` into a string that the postgres +server will understand. + +The caller will provide you with a buffer where you can write the string, if +you need it: from `begin` to `end` exclusive. It's a half-open interval, so +don't access `*end`. + +If the buffer is insufficient for you to do the conversion, throw a +`pqxx::conversion_overrun`. It doesn't have to be exact: you can be a little +pessimistic and demand a bit more space than you need. Just be sure to throw +the exception if there's any risk of overrunning the buffer. + +You don't _have_ to use the buffer for this function though. For example, +`pqxx::string_traits::to_buf` returns a compile-time constant string and +ignores the buffer. + +Even if you do use the buffer, your string does not _have_ to start at the +beginning of the buffer. For example, the integer conversions start by writing +the _least_ significant digit to the _end_ of the buffer, and then writes the +more significant digits before it. It was just more convenient. + +Return a `pqxx::zview`. This is basically a `std::string_view`, but with one +difference: a `zview` guarantees that there will be a valid zero byte right +after the `string_view`. The zero byte is not counted as part of its size, but +it will be there. + +Expressed in code, this rule must hold: + + void invariant(zview z) + { + assert(z[std::size(z)] == 0); + } + +Make sure you write your trailing zero _before_ the `end`. If the trailing +zero doesn't fit in the buffer, then there's just not enough room to perform +the conversion. + +Beware of locales when converting. If you use standard library features like +`sprintf`, they may obey whatever locale is currently set on the system. That +means that a simple integer like 1000000 may come out as "1000000" on your +system, but as "1,000,000" on mine, or as "1.000.000" for somebody else, and on +an Indian system it may be "1,00,000". Values coming from or going to the +database should be in non-localised formats. You can use libpqxx functions for +those conversions: `pqxx::from_string`, `pqxx::to_string`, `pqxx::to_buf`. + + +### `into_buf` + +This is a stricter version of `to_buf`. All the same requirements apply, but +in addition you must write your string into the buffer provided, starting +_exactly_ at `begin`. + +That's why this function returns just a simple pointer: the address right +behind the trailing zero. If the caller wants to use the string, they can +find it at `begin`. If they want to write a different value into the rest of +the buffer, they can start at the location you returned. + + +### `size_buffer` + +Here you estimate how much buffer space you need for converting a `T` to a +string. Be precise if you can, but pessimistic if you must. It's usually +better to waste a few unnecessary bytes than to spend a lot of time computing +the exact buffer space you need. And failing the conversion because you +under-budgeted the buffer is worst of all. + +Include the trailing zero in the buffer size. If your `to_buf` takes more +space than just what's needed to store the result, include that too. + +Make `size_buffer` a `constexpr` function if you can. It can allow the caller +to allocate the buffer on the stack, with a size known at compile time. + + +Optional: Specialise `is_unquoted_safe` +--------------------------------------- + +When converting arrays or composite values to strings, libpqxx may need to +quote values and escape any special characters. This takes time. + +Some types though, such as integral or floating-point types, can never have +any special characters such as quotes, commas, or backslashes in their string +representations. In such cases, there's no need to quote or escape such values +in arrays or composite types. + +If your type is like that, you can tell libpqxx about this by defining: + + namespace pqxx + { + template<> inline constexpr bool is_unquoted_safe{true}; + } + +The code that converts this type of field to strings in an array or a composite +type can then use a simpler, more efficient variant of the code. It's always +safe to leave this out; it's _just_ an optimisation for when you're completely +sure that it's safe. + +Do not do this if a string representation of your type may contain a comma; +semicolon; parenthesis; brace; quote; backslash; newline; or any other +character that might need escaping. + + +Optional: Specialise `param_format` +----------------------------------- + +This one you don't generally need to worry about. Read on if you're writing a +type which represents raw binary data, or if you're writing a template where +_some specialisations_ may contain raw binary data. + +When you call parameterised statements, or prepared statements with parameters, +libpqxx needs to your parameters on to libpq, the underlying C-level PostgreSQL +client library. + +There are two formats for doing that: _text_ and _binary._ In the first, we +represent all values as strings, and the server then converts them into its own +internal binary representation. That's what the string conversions are all +about, and it's what we do for almost all types of parameters. + +But we do it differently when the parameter is a contiguous series of raw bytes +and the corresponding SQL type is `BYTEA`. There is a text format for those, +but we bypass it for efficiency. The server can use the binary data in the +exact same form, without any conversion or extra processing. The binary data +is also twice as compact during transport. + +(People sometimes ask why we can't just treat all types as binary. However the +general case isn't so clear-cut. The binary formats are not documented, there +are no guarantees that they will be platform-independent or that they will +remain stable, and there's no really solid way to detect when we might get the +format wrong. But also, the conversions aren't necessarily as straightforward +and efficient as they sound. So, for the general case, libpqxx sticks with the +text formats. Raw binary data alone stands out as a clear win.) + +Long story short, the machinery for passing parameters needs to know: is this +parameter a binary string, or not? In the normal case it can assume "no," and +that's what it does. The text format is always a safe choice; we just try to +use the binary format where it's faster. + +The `param_format` function template is what makes the decision. We specialise +it for types which may be binary strings, and use the default for all other +types. + +"Types which _may_ be binary"? You might think we know whether a type is a +binary type or not. But there are some complications with generic types. + +Templates like `std::shared_ptr`, `std::optional`, and so on act like +"wrappers" for another type. A `std::optional` is binary if `T` is binary. +Otherwise, it's not. If you're building support for a template of this nature, +you'll probably want to implement `param_format` for it. + +The decision to use binary format is made based on a given object, not +necessarily based on the type in general. Look at `std::variant`. If you have +a `std::variant` type which can hold an `int` or a binary string, is that a +binary parameter? We can't decide without knowing the individual object. + +Containers are another hard case. Should we pass `std::vector` in binary? +Even when `T` is a binary type, we don't currently have any way to pass an +array in binary format, so we always pass it as text. diff --git a/ext/libpqxx-7.7.3/include/pqxx/doc/escaping.md b/ext/libpqxx-7.7.3/include/pqxx/doc/escaping.md new file mode 100644 index 000000000..2ad9fe3db --- /dev/null +++ b/ext/libpqxx-7.7.3/include/pqxx/doc/escaping.md @@ -0,0 +1,74 @@ +String escaping {#escaping} +=============== + +Writing queries as strings is easy.

But for those cases where efficiency +matters, there are two classes to help you do this better: `stream_from` and +`stream_to`. They're less flexible than SQL queries, and there's the risk of +losing your connection while you're in mid-stream, but you get some speed and +memory efficiencies in return. + +Both stream classes do data conversion for you: `stream_from` receives values +from the database in PostgreSQL's text format, and converts them to the C++ +types you specify. Likewise, `stream_to` converts C++ values you provide to +PostgreSQL's text format for transfer. (On its end, the database of course +converts values to and from their SQL types.) + + +Null values +----------- + +So how do you deal with nulls? It depends on the C++ type you're using. Some +types may have a built-in null value. For instance, if you have a +`char const *` value and you convert it to an SQL string, then converting a +`nullptr` will produce a NULL SQL value. + +But what do you do about C++ types which don't have a built-in null value, such +as `int`? The trick is to wrap it in `std::optional`. The difference between +`int` and `std::optional` is that the former always has an `int` value, +and the latter doesn't have to. + +Actually it's not just `std::optional`. You can do the same thing with +`std::unique_ptr` or `std::shared_ptr`. A smart pointer is less efficient than +`std::optional` in most situations because they allocate their value on the +heap, but sometimes that's what you want in order to save moving or copying +large values around. + +This part is not generic though. It won't work with just any smart-pointer +type, just the ones which are explicitly supported: `shared_ptr` and +`unique_ptr`. If you really need to, you can build support for additional +wrappers and smart pointers by copying the implementation patterns from the +existing smart-pointer support. + + +stream\_from +------------ + +Use `stream_from` to read data directly from the database. It's faster than +the transaction's `exec` functions if the result contains enough rows. But +also, you won't need to keep your full result set in memory. That can really +matter with larger data sets. + +And, you can start processing your data right after the first row of data comes +in from the server. With `exec()` you need to wait to receive all data, and +then you begin processing. With `stream_from` you can be processing data on +the client side while the server is still sending you the rest. + +You don't actually need to create a `stream_from` object yourself, though you +can. Two shorthand functions, @ref pqxx::transaction_base::stream +and @ref pqxx::transaction_base::for_each, can create the streams for you with +a minimum of overhead. + +Not all kinds of queries will work in a stream. Internally the streams make +use of PostgreSQL's `COPY` command, so see the PostgreSQL documentation for +`COPY` for the exact limitations. Basic `SELECT` and `UPDATE ... RETURNING` +queries should just work. + +As you read a row, the stream converts its fields to a tuple type containing +the value types you ask for: + + auto stream pqxx::stream_from::query( + tx, "SELECT name, points FROM score"); + std::tuple row; + while (stream >> row) + process(row); + stream.complete(); + +As the stream reads each row, it converts that row's data into your tuple, +goes through your loop body, and then promptly forgets that row's data. This +means you can easily process more data than will fit in memory. + + +stream\_to +---------- + +Use `stream_to` to write data directly to a database table. This saves you +having to perform an `INSERT` for every row, and so it can be significantly +faster if you want to insert more than just one or two rows at a time. + +As with `stream_from`, you can specify the table and the columns, and not much +else. You insert tuple-like objects of your choice: + + pqxx::stream_to stream{ + tx, + "score", + std::vector{"name", "points"}}; + for (auto const &entry: scores) + stream << entry; + stream.complete(); + +Each row is processed as you provide it, and not retained in memory after that. + +The call to `complete()` is more important here than it is for `stream_from`. +It's a lot like a "commit" or "abort" at the end of a transaction. If you omit +it, it will be done automatically during the stream's destructor. But since +destructors can't throw exceptions, any failures at that stage won't be visible +in your code.

It's better than the + * "repeatable read" defined in the SQL standard, but not a complete + * implementation of the standard's "serializable" isolation level. + * + * In general, a lower isolation level will allow more surprising interactions + * between ongoing transactions, but improve performance. A higher level + * gives you more protection from subtle concurrency bugs, but sometimes it + * may not be possible to complete your transaction without avoiding paradoxes + * in the data.

The right way + * to handle those failures is often just to re-run the transaction from + * scratch. + * + * For example, your REST API might be handling each HTTP request in its own + * database transaction, and if this kind of transient failure happens, you + * simply want to "replay" the whole request, in a fresh transaction. + * + * You won't necessarily want to execute the exact same SQL commands with the + * exact same data. Some of your SQL statements may depend on state that can + * vary between retries. Data in the database may already have changed, for + * instance. So instead of dumbly replaying the SQL, you re-run the same + * application code that produced those SQL commands, from the start. + * + * The transactor framework makes it a little easier for you to do this safely, + * and avoid typical pitfalls. You encapsulate the work that you want to do + * into a callable that you pass to the @ref perform function. + * + * Here's how it works. You write your transaction code as a lambda or + * function, which creates its own transaction object, does its work, and + * commits at the end. You pass that callback to @ref pqxx::perform, which + * runs it for you. + * + * If there's a failure inside your callback, there will be an exception. Your + * transaction object goes out of scope and gets destroyed, so that it aborts + * implicitly. Seeing this, @ref perform tries running your callback again. It + * stops doing that when the callback succeeds, or when it has failed too many + * times, or when there's an error that leaves the database in an unknown + * state, such as a lost connection just while we're waiting for the database + * to confirm a commit. It all depends on the type of exception. + * + * The callback takes no arguments. If you're using lambdas, the easy way to + * pass arguments is for the lambda to "capture" them from your variables. Or, + * if you're using functions, you may want to use `std::bind`. + * + * Once your callback succeeds, it can return a result, and @ref perform will + * return that result back to you. + */ +//@{ + +/// Simple way to execute a transaction with automatic retry. +/** + * Executes your transaction code as a callback.

This can happen if the network + * connection to the server is lost just while we're waiting for its reply to + * a "commit" statement.

PostgreSQL is built on the + * MVCC paradigm, which guarantees "read committed" isolation without any + * additional performance overhead, so there was no point in providing the + * lower level. + * + * Second, "repeatable read" also makes more isolation guarantees than the + * standard requires.

In postgres, + * it actually prevents all three. + * + * Third, "serializable" is only properly supported starting at postgres 9.1. + * If you request "serializable" isolation on an older backend, you will get + * the same isolation as in "repeatable read." It's better than the + * "repeatable read" defined in the SQL standard, but not a complete + * implementation of the standard's "serializable" isolation level. + * + * In general, a lower isolation level will allow more surprising interactions + * between ongoing transactions, but improve performance. A higher level + * gives you more protection from subtle concurrency bugs, but sometimes it + * may not be possible to complete your transaction without avoiding paradoxes + * in the data. In that case a transaction may fail, and the application will + * have to re-do the whole thing based on the latest state of the database. + * (If you want to retry your code in that situation, have a look at the + * transactor framework.) + * + * Study the levels and design your application with the right level in mind. + */ +enum isolation_level +{ + // PostgreSQL only has the better isolation levels. + // read_uncommitted, + + read_committed, + repeatable_read, + serializable, +}; +} // namespace pqxx +#endif diff --git a/ext/libpqxx-7.7.3/install/ubuntu22.04/include/pqxx/largeobject b/ext/libpqxx-7.7.3/install/ubuntu22.04/include/pqxx/largeobject new file mode 100644 index 000000000..1f2f94790 --- /dev/null +++ b/ext/libpqxx-7.7.3/install/ubuntu22.04/include/pqxx/largeobject @@ -0,0 +1,8 @@ +/** Large Objects interface. + * + * Supports direct access to large objects, as well as through I/O streams + */ +// Actual definitions in .hxx file so editors and such recognize file type. +#include "pqxx/internal/header-pre.hxx" +#include "pqxx/largeobject.hxx" +#include "pqxx/internal/header-post.hxx" diff --git a/ext/libpqxx-7.7.3/install/ubuntu22.04/include/pqxx/largeobject.hxx b/ext/libpqxx-7.7.3/install/ubuntu22.04/include/pqxx/largeobject.hxx new file mode 100644 index 000000000..ebafc51d8 --- /dev/null +++ b/ext/libpqxx-7.7.3/install/ubuntu22.04/include/pqxx/largeobject.hxx @@ -0,0 +1,735 @@ +/* Large Objects interface.

The right way + * to handle those failures is often just to re-run the transaction from + * scratch. + * + * For example, your REST API might be handling each HTTP request in its own + * database transaction, and if this kind of transient failure happens, you + * simply want to "replay" the whole request, in a fresh transaction. + * + * You won't necessarily want to execute the exact same SQL commands with the + * exact same data. Some of your SQL statements may depend on state that can + * vary between retries. Data in the database may already have changed, for + * instance. So instead of dumbly replaying the SQL, you re-run the same + * application code that produced those SQL commands, from the start. + * + * The transactor framework makes it a little easier for you to do this safely, + * and avoid typical pitfalls. You encapsulate the work that you want to do + * into a callable that you pass to the @ref perform function. + * + * Here's how it works. You write your transaction code as a lambda or + * function, which creates its own transaction object, does its work, and + * commits at the end. You pass that callback to @ref pqxx::perform, which + * runs it for you. + * + * If there's a failure inside your callback, there will be an exception. Your + * transaction object goes out of scope and gets destroyed, so that it aborts + * implicitly. Seeing this, @ref perform tries running your callback again. It + * stops doing that when the callback succeeds, or when it has failed too many + * times, or when there's an error that leaves the database in an unknown + * state, such as a lost connection just while we're waiting for the database + * to confirm a commit. It all depends on the type of exception. + * + * The callback takes no arguments. If you're using lambdas, the easy way to + * pass arguments is for the lambda to "capture" them from your variables. Or, + * if you're using functions, you may want to use `std::bind`. + * + * Once your callback succeeds, it can return a result, and @ref perform will + * return that result back to you. + */ +//@{ + +/// Simple way to execute a transaction with automatic retry. +/** + * Executes your transaction code as a callback.
