New issue: emails get stuck in Mail/Incoming* files

New issue: emails get stuck in Mail/Incoming* files

[Francis Moreau]

Hello

I'm facing with a new issue with Gnus.

All my emails (fetched by fetchmail into /var/spool directory) are
moved by Gnus to Mail/Incoming* files, but now they don't appear
anymore in my Inbox group.

Could anybody tell me what's happening ?

Thanks

I can explain that:

Well, here I don't know why...

Yes, I already set mail-source-delete-incoming to nil since I don't
want to loose any emails until this problem is fixed.

It looks like the split process, the one which deliver each email to
the right group is not working/called anymore.

This might be due to an unexpected power-off that leads to a
corruption of a Gnus' file or something similar.

Do you have an idea, how I can debug this ?

Thanks

Hm, to see where the splitting process delivered a mail, you can use
this.

,----[ (info "(gnus)Splitting Mail") ]
|    If you wish to see where the previous mail split put the messages,
| you can use the `M-x nnmail-split-history' command.
`----

But most probably this doesn't show anything, because you said that they
don't show up in any inbox.

I had a similar thing when upgrading from dovecot 1.1 to 1.2 (that's my
local imap server).  In 1.1, the dot was used as separator while in 1.2
it is a /.  So the old foo.bar group didn't get any new messages.  Then,
I found out that I had to enter the server buffer and subscribe to
foo/bar and friends, which contained all the new and the old mails.

But I guess you use nnml or nnmaildir, right?

No this doesn't help since the emails seem not going through the split
process and stay at the 'Incoming' stage.

I took a look to the server buffer, but nothing wrong I can notice
unfortunately.

yes I use nnml.

So I guess I need to debug this with a debuger, but I was wondering if
you or someone else have any hints since I'm going to have hard time
to find out what's going on...

Thanks

Ok, I found something...

To fetch new emails, I'm doing 'g' in the group buffer. However I just
redefined this key binding so it fetchs only emails for groups whose
levels are 1 or 2:

   (defun my-gnus-group-get-new-news (level)
     (interactive "P")
     (gnus-group-get-new-news (or level 2))
     (gnus-group-list-groups))

   (define-key gnus-group-mode-map [?g] 'my-gnus-group-get-new-news)

And it happens to cause the issue I'm currently facing: if I remove
this binding and therefore call a 'raw' gnus-group-get-new-news() when
pressing 'g' it works as expected.

I actually did another test without redefining 'g' binding: I did "C-u
2 g" to rescan emails for group levels 1, 2 and it fails the same way
as before.

So either I haven't understand gnus-group-get-new-news documentation,
or this function is boggus.

See if I can understand that code...

I don't use nnml and no mail spool, so I don't have any expertise there.
You might want to do `M-x toggle-debug-on-error' before looking for new
mail, just to ensure that there's no error thrown somewhere.

Maybe there's some message in *Messages*?

nothing.

Please have a look to my post:

Hm, looks all good to me.  Try to edebug that function and see where it
differs with and without level.

Is there another news group where development on Gnus are discussed ?

Thanks

There is the ding@gnus.org mailing list which is also accessible via
gmane (gmane.emacs.gnus.general).

Ok, I think I'll use this one, it's funny to see that Gnus development
discussions happen on a mailing list and not on a news group.

I posted my question 2 days ago and cannot see it from
gmane.emacs.gnus.general.

Should I be subscribed to post on this mailing lists ?

I would think no since I haven't received any reply asking me to
subscribe before posting.

I don't use that group but the mailinglist.  But I think I used it
somewhere in the past.  Normally, you should get a gmane confirmation
message from gmane the first time you post to a group, which you have to
reply to.

If you didn't get it, maybe try again.

Sorry I wasn't cleared: I did send a mail to the mailing list but
since I'm not subscribed, I use gmane.emacs.gnus.general to check that
my email reached the mailing list and I can't see it.

But I'll retry as you suggested.

Thanks

I'm subscribed to ding, and there's no message from you.  So maybe you
have to be subscribed to post to the list.  Hm, maybe try to post via
the gmane group, or subscribe to the list.

Ok I give up, after subscribing to this list, it still doesn't work :(
