Reconnect fails when redis is in subscribe mode

[guimard]

Hi,

thanks a lot for Redis.pm. Anyway when we use a Redis object to subscribe to a channel, the reconnect mechanism always fail to reconnect to a restarted server when a password is asked. This is due to __is_valid_command which check that we're not in subscribe mode, so the "AUTH" command is never sent: Cannot use command 'auth' while in SUBSCRIBE mode, at /usr/share/perl5/vendor_perl/Redis.pm.

Best regards,
Xavier
