nnimap+agent+registry -> ghost articles

[Raymond Scholz <ray-2004@zonix.de>]

Hi,

I'm using nnimap with the gnus registry (splitting with parent) and
the agent for caching overviews to increase speed.  Most of my mail is
split by maildrop into Maildirs on the IMAP server.  Anything else is
put into the IMAP INBOX which will then be split by Gnus using the
registry information.  Some articles end up in INBOX since the
registry has no information on their parents.  These articles drive
Gnus nuts.

;; registry setup
(gnus-registry-initialize)
(setq gnus-registry-max-entries 20000)
(setq gnus-registry-use-long-group-names t)
(setq gnus-registry-unfollowed-groups
      '("delayed"
	"drafts"
	"queue"
	"sent\\.mail"
	"sent\\.news"
	"^nnrss:"
	"^nntp:"
	))

;; nnimap + splitting setup
(setq nnimap-split-rule 'nnimap-split-fancy)
(setq nnimap-split-fancy
      '(|
	(: gnus-registry-split-fancy-with-parent)
	"INBOX"))

(setq nnimap-split-inbox '("INBOX"))
(setq nnimap-split-predicate "UNDELETED")
(setq nnimap-split-crosspost nil)

(setq gnus-use-cache t)

Gnus from CVS, just a few minutes ago.

To reproduce the ghost articles I sent myself an email to
rscholz@localhost which ends up in INBOX after hitting `g'.

~/News/agent/nnimap/unnamed/INBOX/.overview contains a line:

4419	test - 02	Raymond Scholz <rscholz@zonix.de>	Wed, 07 Jul 2004 22:11:25 +0200	<.877jtfmvbm@hush.zonix.de>		1008	4	Xref: hush.zonix.de INBOX:4409	To: rscholz@localhost	Content-Type: text/plain; charset=iso-8859-1	

and ~/.gnus.registry.eld a line

("<.877jtfmvbm@hush.zonix.de>" ((mtime 16620 22872 767890)) "nnimap:INBOX")

So far, so good.

Now I hit `g' again.  The article in INBOX is passed to the Gnus
splitting process again, which shouldn't hurt.  But the article count
in the Group buffer indicates two unread articles in INBOX now.
Entering the group shows the duplicated articles which can both be
displayed.

And ~/News/agent/nnimap/unnamed/INBOX/.overview contains

4419	test - 02	Raymond Scholz <rscholz@zonix.de>	Wed, 07 Jul 2004 22:11:25 +0200	<.877jtfmvbm@hush.zonix.de>		1008	4	Xref: hush.zonix.de INBOX:4409	To: rscholz@localhost	Content-Type: text/plain; charset=iso-8859-1	
4420	test - 02	Raymond Scholz <rscholz@zonix.de>	Wed, 07 Jul 2004 22:11:25 +0200	<.877jtfmvbm@hush.zonix.de>		1008	4	Xref: hush.zonix.de INBOX:4409	To: rscholz@localhost	Content-Type: text/plain; charset=iso-8859-1	

and ~/.gnus.registry.eld ends with 

("<.877jtfmvbm@hush.zonix.de>" ((mtime 16620 22872 767890)) "nnimap:INBOX" "nnimap:INBOX")

Subsequent invocations of `gnus-group-get-new-news' add more lines in
the overview file and more entries for the respective message ID in
the registry.

The real pain starts when I delete the article or move it to another
folder.  Deletion of ghost articles doesn't work ("Couldn't delete
articles (4420 4421)") and I usually end up with rm -rf
~/News/agent/nnimap/ and a restart of Gnus.

Cheers, Ray
