Only named arrays are explicitly accepted now, but the old behaviour
of creating a connection parameters instance out of an URI string or
a named array is still available using the "create()" static method.
$array = ['host' => '127.0.0.1', 'timeout' => 1];
$uri = 'tcp://127.0.0.1?timeout=1';
$parameters = new ConnectionParameters($array); // Arrays only
$parameters = ConnectionParameters::create($array); // Arrays OK
$parameters = ConnectionParameters::create($uri); // Strings OK
The purpose of the change is to have a more concise constructor with a
well defined signature.
List of changes:
- 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.
- $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.
We must always execute ASKING on the connection identified by the -ASK
response before executing the actual command because not doing so will
break the cluster specifications while redis-cluster is performing a
resharding operation.
This commit reflects the recent change from the redis unstable branch
in which the number of hash slots was increased from 4096 to 16384.
