Thanks to Dean Mao and Austin Chau.
When a Redis server starts up, it might take a while to load the dataset into memory. During this time, the server will accept connections, but will return errors for all non-INFO commands. Now node_redis will send an INFO command whenever it connects to a server. If the info command indicates that the server is not ready, the client will keep trying until the server is ready. Once it is ready, the client will emit a "ready" event as well as the "connect" event. The client will queue up all commands sent before the server is ready, just like it did before. When the server is ready, all offline/non-ready commands will be replayed. This should be backward compatible with previous versions. To disable this ready check behavior, set `options.no_ready_check` when creating the client. As a side effect of this change, the key/val params from the info command are available as `client.server_options`. Further, the version string is decomposed into individual elements in `client.server_options.versions`.
Thanks to Gustaf Sjöberg.
…p error properly.
See examples/extend.js for a simple example. Remove command list from exports while I was in there.
