(Org as of 2008-12-08, Gnus/5.110009 (No Gnus v0.9), XEmacs/21.4.21 (linux))
Hi,
I've encountered a problem with `org-gnus-follow-link' which sometimes
fails to fetch the appropriate article in Gnus. This does not happen
when a buffer is visiting the group the link points to.
After a bit of investigation I found out that the problem is
`gnus-group-read-group' which is called by `org-gnus-follow-link'.
`gnus-group-read-group' does not return an article but nil if the last
message of the group has been deleted (this is re-producable here).
Inserting a new article into the group (e.g. by moving an article from
that group into the same group again) solves the problem.
I'm not quite sure how to address the problem or the other way round: is
this a bug in `gnus-group-read-group' that should never return nil if
the first argument is 1 and there's at least one article in the group or
is it a bug in `org-gnus-follow-link' that counts on
`gnus-group-read-group' returning an article.

Not really. But it won't open the Summary buffer if the last article
was deleted.
Please try this patch and report back if it works.

this works in principle but is not really an option. Since first
argument 't' to `gnus-group-read-group' makes every article readable in
a group, building the summary buffer takes far too long for groups with
many articles. Try it with groups containing 10.000+ articles and you'll
see what I mean.

Normally you should be asked how many articles you wanna see, if the
group is big. If that's not the case for you, you have customized
something which controls that.
But indeed, it doesn't solve the real problem. Even if it asks and the
user says 100 but deleted the last 100 messages in that group before,
it'll react as it is now.
I'll ask at the gnus towers...

hmmm, I'm not aware I've ever done something like that but since my Gnus
config evolved over several years I cannot completely exclude this
possibility. I know the behaviour you've mentioned from nntp groups,
maybe it's different with the nnml backend (I was actually testing this
with nnml).

D'accord.

Unfortunately, it doesn't work. The behaviour is the same as with the
original version: jumping to the article works if the last article in
the group in question hasn't been deleted, otherwise it fails.

I tried exactly that and it solved the problem for me. Did you apply
the patch and eval the function thereafter? Or did you recompile
org-mode if you restarted emacs for the test?

huh, that's strange. The patched version was really in effect here when
the tests failed. I've just updated Gnus to the latest (CVS) version but
again, it's not fixed for me ... and maybe it cannot be fixed. The whole
subject reminds me of the old Gnus "wrong article count problem". AFAIK
there was never a solution for this apart from moving articles into
groups or temporarily renaming groups (see also
`gnus-group-compact-group').

Exactly that's the problem.
Please do a test for me:
1. Enter a group in Gnus
2. Delete the last article
3. Exit summary
4. Try `C-u 1 RET' on the group. It should issue "No unread news".
5. Do `M-: (gnus-activate-group "<group-name>" t) RET'
6. Try `C-u 1 RET' on the group again. Now it should be opened and
summary should contain one article.
If you get different results it seems to be due to your gnus version. I
use the one included in emacs 23 and update daily, so it might be more
up to date than your copy. Maybe try to update yours, too.

done that. I was under the wrong impression that the CVS on cvs.gnus.org
holds the latest version of Gnus but it seems it just has the release
from 1st May. It seems that latest Gnus is now available from the Emacs
CVS only (sorry for my ignorance). I installed that version here (5.13
as of today, see User-Agent header) but again the summary buffer is not
opened. Do you know (and remember) what has changed in Gnus sources
since 1st May that made the "wrong article count"-bug go away?

There's nothing to excuse. I wasn't aware that the versions diverged
that much, too.

How? Did you checkout GNU Emacs and copy all the gnus-related files
somewhere?

That's really strange. BTW: What backend did you use for testing? I
used nnimap. MAybe that makes the difference...

No, till that date there were 111 commits in emacs/lisp/gnus.

yes, I really was surprised ... especially as gnus.org offers a 'nightly
snapshot' that also seems to be the version as of 1st May.

Exactly, I got emacs sources by CVS and used the lisp/gnus/ files (plus
some other lisp files from gnus.org that where missing and XEmacs seems
to require). Byte-Compiling here with XEmacs 21.4 went smoothly, Gnus
runs as before ... at least until now ;)

Gotcha! It works on nnimap but not on nnml which I was using for the
tests. Maybe you'll try this with your installation as well. If it fails
for nnml groups for you, too, that might be an important point for the
discussion you've started on emacs.gnus.general.

I can reproduce it with nnml. Damn! I posted to ding. Did you get a
"I want a string but got nil" error, too?

Yeah, done so.

this works after some modifications (patch attached). XEmacs does not
know `substring-no-properties' but org-compat has
`org-substring-no-properties'. Besides, my Gnus holds
`gnus-large-newsgroup' as a string not as integer.
Unfortunately, this is not an ideal solution but from what I've read
from the Gnus gurus the best that can be done until the problems with
nnml are resolved.
Nevertheless, your patch has the great advantage that is should work
with all links to nnml group articles (I agree, more than 1-
gnus-large-newsgroup articles in a group are rather seldom).

Just one other comment: After failure to get a summary buffer by reading
the last article you try it with reading 1- gnus-large-newsgroup
articles. I'd assume that in most cases where the first call to
gnus-group-read-group fails only one or a few more articles have been
deleted in the group in question. In that case, it might be quicker if
`org-gnus-follow-link' increases the number of articles to be read by
one and tries `gnus-group-read-group' again until the call succeeds. If
I find the time tomorrow I will test that. What do you think?
Ulf

What?!? Do you set it somewhere? The docs say it should be a number or
nil.

Yeah, I'll implement like that. But incrementing one by one is not
optimal. When a user deletes all messages (including the linked one)
the summary cannot be opened anyway and you'll loop till the maximum
integer (or whatever you use as upper bound). So I think I'll try
increasing by one till 16 and then start doubling.

Yes, I was investigating that, too ... and indeed I found that the value
was user set. What had driven me to set it as string remains a mystery
to me, I wasn't even aware I'd ever touched that value. So I think it's
save to assume that `gnus-large-newsgroup' is an integer or nil ;)

Yes, increasing the interval is certainly a good idea. But how about
using the Fibonacci sequence (1, 2, 3, 5, 8 ...) for this :)

The fibonacci sequence increases too slow. The current implementation
(which should hit the main tree soon) increases step by step till 16 and
then doubles the value till an integer overflow occurs. Normally, that
cannot happen, only if the group is empty. But in that case gnus
signals a quit condition, which is handled now with an appropriate
message.
If you're impatient you can pull from
git://www.tsdh.de/org-mode.git
instead of waiting till Carsten pulled the changes.

Carsten already did that. The new version works fine. Thanks for your
effort :)))))
