Bug with gnus agent when processing message queue and having archive alist

Bug with gnus agent when processing message queue and having archive alist

[Matt Ford]

Hi,

If I come back from unplugged mode and try to send the queue with `J S'
and I have the following set then:

(setq gnus-message-archive-group
      '(("Manchester:INBOX" "nnimap+Manchester:INBOX")
        ("Dancingfrog:INBOX" "nnimap+Dancingfrog:INBOX")))

things fail like this...

  gnus-inews-insert-gcc: Wrong type argument: stringp, nil

Which also explains my previous double post, so sorry about that.  Any
suggested work arounds?

Cheers,

This is probably related to the fact that doing a `C-u m' on a topic
item with the gnus-message-archive-group configured with an a-list also
fails.

I'm guessing in both cases there is no group set for the regexs to match
to.  Wildcard match doesn't help either (but I'm a bit out of my depth
with this).

Okay, here's a patch to make it work.  Probably not the right one but it
does the job.  Essentially if the gnus-message-archive-group is set then
the gnus-inews-insert-gcc function will try a string comparison on the
optional group parameter even if the group parameter is not set.
Providing an empty string stops the wrong type error.

Cheers,

Matt.

I suspect that's not the correct fix, since it does actions later based
on whether `group' is nil or not.

Here it is: the string "Manchester:" is the first regex of my alist.
There's no check before the string-match to see if group has actually
been defined which is why forcing it "" works...

It's easy to invoke the bug, in title mode use the arrow keys to move
the cursor to a title heading and `C-u m'.  One sees it also on return
from unplugged mode.

I've applied the patch below to No Gnus.  Does it fix the problem?

Title heading?

Apologies, by title heading I mean topic heading in the Group buffer - basically
any line that's not a group when kicking of a message using `C-u m'.

Ah, right.

Well, with the change I applied, I'm not getting any backtrace...

Re: Bug with gnus agent when processing message queue and having archive alist

[Matt Ford]

hmm - doesn't quite work for me.  It now looks to be trying to evaluate
the regex rather than matching it.

Debugger entered--Lisp error: (invalid-function "Manchester:")
  ("Manchester:" "nnimap+Manchester:Sent Items")
  eval(("Manchester:" "nnimap+Manchester:Sent Items"))
  gnus-inews-insert-gcc()
  run-hooks(message-header-setup-hook)
  message-setup-1(((To . "") (Subject . "")) nil nil nil)
  message-setup(((To . "") (Subject . "")) nil nil nil nil nil)
  message-mail()
  gnus-group-mail((4))
  call-interactively(gnus-group-mail nil nil)

Here's my setting:

(setq gnus-message-archive-group '(("Manchester:" "nnimap+Manchester:Sent Items")
                                   ("Dancingfrog:" "nnimap+Dancingfrog:[Google Mail]/Sent Mail")
                                   (quote "sent")))

Perhaps a final check is needed?
(cond
                	((and group
	                      (stringp (caar var)))
                      	       ;; Regexp.

Yup.  I've now applied a new patch to No and Ma to try to fix this.

`(setq debug-on-error t)', repeat the bug and post the resulting
backtrace.
