v0.6.0 (2010-05-??) * Switched to the new multi-bulk request protocol for all of the commands in the Redis 1.2 and Redis 2.0 profiles. Inline and bulk requests are now deprecated as they will be removed in future releases of Redis. * The default server profile is "2.0" (targeting Redis 2.0.x). If you are using older versions of Redis, it is highly recommended that you specify which server profile the client should use (e.g. "1.2" when connecting to instances of Redis 1.2.x). * Support for Redis 1.0 is now optional and it is provided by requiring 'Predis_Compatibility.php' before creating an instance of Predis\Client. * New commands added to the Redis 2.0 profile since Predis 0.5.1: - Strings: SETEX, APPEND, SUBSTR - ZSets : ZCOUNT, ZRANK, ZUNIONSTORE, ZINTERSTORE, ZREMBYRANK, ZREVRANK - Hashes : HSET, HSETNX, HMSET, HINCRBY, HGET, HMGET, HDEL, HEXISTS, HLEN, HKEYS, HVALS, HGETALL - PubSub : PUBLISH, SUBSCRIBE, UNSUBSCRIBE - Misc. : DISCARD, CONFIG * Introduced client-level options with the new Predis\ClientOptions class. Options can be passed to Predis\Client::__construct in its second argument as an array or an instance of Predis\ClientOptions. For brevity's sake and compatibility with older versions, the constructor of Predis\Client still accepts an instance of Predis\RedisServerProfile in its second argument. The currently supported client options are: - profile [default: "2.0" as of Predis 0.6.0] specifies which server profile to use when connecting to Redis. This option accepts an instance of Predis\RedisServerProfile or a string that indicates the target version. - key_distribution [default: Predis\Distribution\HashRing] specifies which key distribution strategy to use to distribute keys among the servers that compose a cluster. This option accepts an instance of Predis\Distribution\IDistributionStrategy so that users can implement their own key distribution strategy. Optionally, the new Predis\Distribution\KetamaPureRing class also provides a pure-PHP implementation of the same algorithm used by libketama. - throw_on_error [default: TRUE] server errors can optionally be handled "silently": instead of throwing an exception, the client returns an error response type. - iterable_multibulk [EXPERIMENTAL - default: FALSE] in addition to the classic way of fetching a whole multibulk reply into an array, the client can now optionally stream a multibulk reply down to the user code by using PHP iterators. It is just a little bit slower, but it can save a lot of memory in certain scenarios. * New parameters for connections: - alias [default: not set] every connection can now be identified by an alias that is useful to get a certain connection when connected to a cluster of Redis servers. - weight [default: not set] allows the client to balance the keys asymmetrically across multiple servers. This might be useful when you have servers with different amounts of memory and you want to distribute the load of your keys accordingly. - connection_async [default: FALSE] estabilish connections to servers in a non-blocking way, so that the client is not blocked while the underlying resource performs the actual connection. - connection_persistent [default: FALSE] the underlying connection resource is left open when a script ends its lifecycle. Persistent connections can lead to unpredictable or strange behaviours, so they should be used with extreme care. * Introduced the Predis\Pipeline\IExecutor interface. Classes implementing this interface are now used internally by the Predis\CommandPipeline class to change the behaviour of the pipeline when writing/reading commands from one or multiple servers. Here is the list of the default executors: - Predis\Pipeline\StandardExecutor Exceptions generated by server errors might be thrown depending on the options passed to the client (see "throw_on_error"). Instead, protocol or network errors always throw exceptions. This is the default executor for single and clustered connections and shares the same behaviour of Predis 0.5.x. - Predis\Pipeline\SafeExecutor Exceptions generated by server, protocol or network errors are not thrown, instead they are returned in the response array as instances of ResponseError or CommunicationException. - Predis\Pipeline\SafeClusterExecutor This executor shares the same behaviour of Predis\Pipeline\SafeExecutor but it is geared towards clustered connections. * Support for PUBSUB is handled by the new Predis\PubSubContext class, which could also be used to build a callback dispatcher for PUBSUB scenarios. * When connected to a cluster of connections, it is now possible to get a new Predis\Client instance for a single connection of the cluster by passing its alias/index to the new Predis\Client::getClientFor() method. * CommandPipeline and MultiExecBlock return their instances when invoking commands, thus allowing method chaining in pipelines and multi-exec blocks. * MultiExecBlock instances can handle the new DISCARD command. * Connections now support float values for the connection_timeout parameter to express timeouts with a microsecond resolution. * The GET parameter for the SORT command now accepts also multiple key patterns by passing an array of strings. v0.5.1 (2010-01-27) * RPOPLPUSH has been changed from bulk command to inline command in Redis 1.2.1, so ListPopLastPushHead now extends InlineCommand. The old RPOPLPUSH behavior is still available via the ListPopLastPushHeadBulk class so that you can override the server profile if you need the old (and uncorrect) behaviour when connecting to a Redis 1.2.0 instance. * Added missing support for BGREWRITEAOF for Redis >= 1.2.0 * Implemented a factory method for the RedisServerProfile class to ease the creation of new server profile instances based on a version string. v0.5.0 (2010-01-09) * First versioned release of Predis
