"punsubscribe *" does not unsubscribe from channel "foo" #529

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What version of Redis you are using, in what kind of Operating System?
I have tested this on 2.2.4 and master as of the date of submission.  I'm using 
Mac OS 10.6.

What is the problem you are experiencing?
Running the command "punsubscribe *" does not unsubscribe from all the channels 
that the proc is subscribed to.  My expectation, perhaps wrongly, is that 
"punsubscribe *" should unsubscribe me from all the channels I am subscribed 
to, and thus be more or less equivalent to unsubscribe.
However, even if that semantic is wrong, I still expect "punsubscribe f*" to 
unsubscribe me from channel "foo", but this does not appear to be happening 
either.

What steps will reproduce the problem?
It is hard to reproduce this, because redis-cli doesn't seem to support 
unsubscribing.  Therefore, I have written up a small c program using hiredis 
that recreates the problem.  It is attached, and also available as a gist: 
https://gist.github.com/927538 .  I am not a great *nix C coder, so my 
apologies if there are any atrocities against good taste in there.

Hello, wrong expectation I believe ;) You can subscribe to a pattern, and 
unsubscribe to a pattern.
The pattern will be used to match against messages sent to specific channels, 
not to match channels already existing to subscribe/unsubscribe to those 
channels.

Salvatore
