Lots of improvements! Thanks @Xon!
Unit tests & multi/exec fixes (#89) * Suppress errors on cleanup (and avoid potentially deleting the config files) * The pubsub test crassh on phpredis 3.13 and below, but works with 3.1.4RCx. * All basic tests pass (except pubsub with phpredis which explicitly fails) * Fix-up testMasterSlave test * Give Redis time to exit * Fixup testGetHostAndPort test * Allow php7.x opcache to optimize the array to be vastly more compact, and use an O(1) lookup rater than a array scan of strings. * When in standalone multi() mode, exec() now decodes the result, and discard() destroys any pipelining or multi setup. * Rearange testPipeline & testPipelineTransaction to have the same test functionality. Add tests for zrangebyscore/zrevrangebyscore * Fix pipeline/multi modes for more commands * Shim zRange/zRevRange arguments before they are sent to phpredis & expand test coverage * remove unneeded variable * In fluent mode, credis returns itself * Add test for watch/unwatch, ensure the connection is closed/cleaned up when a pipeline&multi or watch fails. * Use diskless replication and add some delays for initial setup time. * Implement info() command for Sentinel * sentinel tests now wait for replication setup to finish * Run all tests * Restore php5.6 support in Credis_cluster * Compile redis from source so redis-sentinel is available * Tweak travis build * Move binaries to the right directory * Update PATH environment variable rather than move binaries around. * Remove debugging code * Better tolerance of slop in the timeout * Push common code into CredisTestCommon * Use role() instead of info() to reliably get the slave connecting state * Move sleep after connect check * Add waitForSlaveReplication for reliable waiting for master-slave replication
