Using IPv6 with Predis was basically impossible due to various inconsistencies
and bugs through the library, now it is supported by all the connection classes.
Following the standard for IPv6 literal addresses in URI strings, the IP literal
must be enclosed within square brackets when passing the parameters as a string:
$parameters = 'tcp://[2001:db8:0:f101::1]:6379';
See https://tools.ietf.org/html/rfc3986#section-3.2.2 for further details.
This commit also fixes#239 making redis-cluster usable with nodes using IPv6.
Instead of using "unix://" you should just use "unix:":
$old = 'unix:///path/to/redis.sock';
$new = 'unix:/path/to/redis.sock';
The old format should be considered obsolete and will not be supported
starting from the next major release of Predis.
Meh
Falling back to a default timeout values should be done by the connection class
as it is an implementation detail that may vary depending on the backend.
