Contacting server when Leaving a group

Contacting server when Leaving a group

[Harry Putnam]

This problem has started coming every once in a while since I've
started having trouble connecting to gmane easily.

Here is an example of what can happen.

I've left gnus open on a a gmane group.  Went to work on something
else for a while.  When I come back gnus has lost its connection to
gmane.

When I try to leave the group with c, or `ZZ' or any of the commands
that are used for leaving groups, gnus won't let me because it cannot
contact the server.   I have to leave by changing buffers or some
other ungnuslike way.

It just makes me wonder... is it really required to contact a server
in order to leave a group?  Can't  whatever information that is
involved be cashed on gnus or something until the connection is restored?

Yes, thank you for raising this question. I run into this problem with
my nnimap groups as well. One has to switch to the *Group* buffer, then
hit C-^ to reach the *Server* buffer, then try to close the offending
server, or maybe "deny" it, and kill an openssl process on the side, or
kill an associated process buffer, then reopen the server, then go back
to the *Group* buffer, find the group with the asterisk, reenter it,
and, finally, with baited breath, try to leave it again by pressing 'q'.

That's pain and embarrassment recast now as muscle memory.

It would be sufficient to retry opening the server, right?  I've done
this process too and it's a little annoying.

I guess so.  What does it do currently?  What it reports is `unable
contact server...' or similar... I just assumed it did try to open the
server.

Maybe Contacting server and reopening server aren't the same?

But what if an attempted reopening also fails... It does here
sometimes when I do (in server buffer) C (close) O (open).  It usually
works the first time but not always.

AFAIK it just gives up on the server currently if it can't be reached.
I haven't looked at the source code nor do I have the time currently,
but if no one else can I'll put it on my TODO list.

I would have a variable for number of retries (customized per server and
a global one too).
