unix socket about predis

[nrk]

Predis v0.6.x does not offer the ability to use connections different from the standard TCP/IP based one. On the other hand, unix domain socket connections are already supported with v0.7.0-dev (the current master branch) but, as the version tag suggest, this version is actually far from being stable even if it passes the whole test suite, so I usually discourage to use it in production environments.

I might come up with something for the next patch release (v0.6.6) if it's not much work and, more importantly, if the needed changes do not lead to breaking changes of the public API with previous releases in the 0.6 series.

Many thanks for your work! Please do work at your own pace - as you wish. I am convinced that the project is in safe hands:) I understand that you are aware of the problem and sooner or later everything will be implemented

While working today on a complete overhaul of the network connection API for the next major version of Predis, I think I've come up with a decent way to provide Unix domain socket connection that should be compatible with the current implementation of the internals of v0.6.x. I'm not quite sure of it yet, I will test this later or tomorrow at worst.

OK, I've added support for UNIX domain sockets in Predis v0.6 with this commit. This will be part of the next patch release (v0.6.6) but I don't know when I'll do the actual release. In the meanwhile I think you can use the library from the v0.6 branch (up to the above mentioned commit) since the changes are minimal and you shouldn't encounter any issue.

PS: I haven't aligned the php5.2_backport branch with these changes so let me know if you are using the backported version of Predis, I'll update that branch too.
