Class: RedisBagOStuff - X-Ref
Object caching using Redis (http://redis.io/).| __construct( $params ) X-Ref |
| Construct a RedisBagOStuff object. Parameters are: - servers: An array of server names. A server name may be a hostname, a hostname/port combination or the absolute path of a UNIX socket. If a hostname is specified but no port, the standard port number 6379 will be used. Required. - connectTimeout: The timeout for new connections, in seconds. Optional, default is 1 second. - persistent: Set this to true to allow connections to persist across multiple web requests. False by default. - password: The authentication password, will be sent to Redis in clear text. Optional, if it is unspecified, no AUTH command will be sent. - automaticFailover: If this is false, then each key will be mapped to a single server, and if that server is down, any requests for that key will fail. If this is true, a connection failure will cause the client to immediately try the next server in the list (as determined by a consistent hashing algorithm). True by default. This has the potential to create consistency issues if a server is slow enough to flap, for example if it is in swap death. param: array $params |

| incr( $key, $value = 1 ) X-Ref |
| Non-atomic implementation of incr(). Probably all callers actually want incr() to atomically initialise values to zero if they don't exist, as provided by the Redis INCR command. But we are constrained by the memcached-like interface to return null in that case. Once the key exists, further increments are atomic. param: string $key Key to increase param: int $value Value to add to $key (Default 1) return: int|bool New value or false on failure |
| serialize( $data ) X-Ref |
param: mixed $data return: string |
| unserialize( $data ) X-Ref |
param: string $data return: mixed |
| getConnection( $key ) X-Ref |
| Get a Redis object with a connection suitable for fetching the specified key param: string $key return: array (server, RedisConnRef) or (false, false) |
| logError( $msg ) X-Ref |
| Log a fatal error param: string $msg |
| handleException( RedisConnRef $conn, $e ) X-Ref |
| The redis extension throws an exception in response to various read, write and protocol errors. Sometimes it also closes the connection, sometimes not. The safest response for us is to explicitly destroy the connection object and let it be reopened during the next request. param: RedisConnRef $conn param: Exception $e |
| logRequest( $method, $key, $server, $result ) X-Ref |
| Send information about a single request to the debug log param: string $method param: string $key param: string $server param: bool $result |
