List of changes:
- The cluster connection sends an ASKING command before retrying
a command on a different node when Redis returns a -ASK response.
- The cluster connection can be initialized with a partial list of
nodes, the full slots map will be fetched from Redis itself using
the CLUSTER NODES command.
- The slots map can be optionally retrieved from Redis if the server
returns a -MOVE response, otherwise only the interested slot will
be permanently reassigned to the new target node.
- It is possible to specify a set of common parameters applied to
connections created on the fly when not part of the current pool
upon -MOVE and -ASK responses returned by Redis for redirections.
- $cluster->connect() connects to a random connection in the pool
instead of forcing the connect operation on all the connections.
We now have a base test case class for Predis (namely PredisTestCase)
grouping various commonly used utility methods shared by all of the
tests in the suite, greatly improving reusability.
NOTE: Backported from v0.9-dev.
This commit reflects the recent change from the redis unstable branch
in which the number of hash slots was increased from 4096 to 16384.
