Looking for the variable that controls newsgroup scanning

Looking for the variable that controls newsgroup scanning

[Lloyd Zusman]

I'm making use of several nnimap groups, each of which being defined
within `gnus-secondary-select-methods'.  As far as I can tell, each one
is defined identically, the only difference being their names.

However, only the first of these three gets updated during
`gnus-group-get-new-news'.  I need to enter the other two and
specifically invoke `gnus-summary-rescan-group' in order for them to
notice any new mail that might have arrived.

I suspect that ages ago, I might have set some sort of variable which
prevents all but the first nnimap group from being scanned during
`gnus-group-get-new-news', but I can't for the life of me recall what I
might have done, nor have I been able to find anything within my setup
that seems to affect this behavior.

Could any of you suggest some possible variables or settings that might
control this?

Thanks in advance.

Maybe a clue : do you take advantage of (*the so cool*) (un)plug
feature ?

Ok forget about that it can't be the source of your problems ;)

Maybe you have defined an alist of servers not to be checked during a
g-g-g-n-n ? (at least automatically) 

Last but not least how do you call the function ? 
This is the relevant info section for g-g-g-n-n :

,----[ C-h f gnus-group-get-new-news RET ]
| gnus-group-get-new-news is an interactive compiled Lisp function in `gnus-group'.
| (gnus-group-get-new-news &optional ARG)
| 
| Get newly arrived articles.
| If ARG is a number, it specifies which levels you are interested in
| re-scanning.  If ARG is non-nil and not a number, this will force
| "hard" re-reading of the active files from all servers.
| 
| [back]
`----

Maybe your groups are not on the same level ? Maybe you inhibit some
hooks such as gnus-get-top-news-hook or gnus-get-new-news-hook ?

Sorry if I am not clear but I am still a n00b at trying to help people
getting out of their problems :)

Not that I know of.  Is there such an alist that's a standard part of
gnus?  I did not define my own.

Nope ... all of them are at the same level.  And I invoke the
function with no argument.

You are quite clear, and I thank you sincerely.  This just turns out to
still be a mystery to me.

I don't think so.

It is also a mystery to me. I really don't see why this happens. Did you
check the availability of your servers ? Maybe only one is activated at
a time ? Or there is a problem with gnus-slave ?

If you find out the solution, would you mine to post it here ? I am
quite interested in having it just in case it happens to me ;)

Maybe the groups have different levels?  Hit `S l' on them to find
out (and correct).

All servers are available.  I can access the IMAP servers from the
command line (i.e., "telnet host 143" with no problem), and I can
also get to them via other IMAP clients.

Also ... recall that I mentioned that if I go directly into the group
and invoke `gnus-summary-rescan-group', I see all the new messages.
This problem only occurs with `gnus-group-get-new-news'.

Yes, I will indeed post my solution, once I find it.

Thanks again.

Well, I mentioned in a subsequent message (that you probably didn't get
to yet) that the groups are all at the same level).

I _think_ I originally mentioned that these are nnimap groups (did I?).
Could this be a factor?

Ah, hm.  So you have several nnimap groups, all from the same server,
and they behave differently?  Weird.

You could also try `G e' on those groups to see if the select method
is the same.  Sometimes, people have "nnimap:foo" (including the
quotes) for some groups and (nnimap "foo" ...) (including the
parentheses) for others.  Please convert them all to the "nnimap:foo"
variant.

Does `G E' show a difference?

Yep.

I checked `G e' and `G E', and all look equivalent.  And in each case,
it's "nnimap:foo" and not (nnimap "foo" ...).

And did I mention that when I'm in the summary buffer for any of these
groups, invoking `gnus-summary-rescan-group' will always correctly
detect new messages for each nnimap server?  It's only
`gnus-group-get-new-news' that fails to do that for the 2nd through n-th
imap groups.

You may have hit a bug in that function then or you have a special
setup that prevents it from doing its job the right way.

Well, in my original message in this thread I mentioned that there is
very likely something about my setup which is causing this.  Upon
re-reading that post, you'll see that my purpose in posting was to see
if any of you could suggest the kinds of things that might appear in my
setup which could control this behavior, since I haven't found anything
obvious, myself.

As for the case where it might be a bug, I've been planing to do some
serious investigation/debugging as soon as I have some time.

In fact it is your latest solution to track out what is going on with
this ;) Good luck in this optic :)

I found it: I need to set `nnimap-need-unselect-to-notice-new-mail' in
the select methods for each of my nnimap servers.  It doesn't seem to be
needed with a single nnimap server, but it has to be there for the sake
of the 2nd through nth servers.  I put it on all three select methods,
although perhaps it isn't needed on the first one.  But it doesn't seem
to hurt being there, so I'll leave it.

I'm using Courier IMAP, which the documentation states is a server that
probably needs this setting.

Thanks to all for your help when I was trying to diagnose this.

Just for reference, which version of Courier IMAP is this?  Look at
the first line it writes when you telnet to the IMAP server port.

I'm using the IMAP that comes with the latest release of Courier MTA,
the one named "courier-0.42.2.20030721".  This is the entire IMAP
