[Gnus v5.8.8] missing article headers in gnus-agent

[Gnus v5.8.8] missing article headers in gnus-agent

[Micha Wiedenmann]

Hi,

no news is not always good news!

Gnus-agent didn't display me some messages from de.comm.software.gnus.
I wonder what else I may have missed. It seems to me that under certain
circumstances gnus-agent didn't fetch all headers:

The headers for the articles 4766, 4767, 4768, 4769, 4770, 4772, 4773
are missing. I think the belong to one session. 

The missing overviews:

To get the old headers I changed `gnus-agent-fetch-headers':

| (defun gnus-agent-fetch-missing-headers (group &optional force)
|
|   ;; don't believe unread articles, get a list of all articles instead unread
|   (let ((articles (gnus-uncompress-range (gnus-active group))) 
| ;;(let ((articles (gnus-list-of-unread-articles group))
| 
| 	(gnus-decode-encoded-word-function 'identity)
| 	(file (gnus-agent-article-name ".overview" group)))
|     ;; Add article with marks to list of article headers we want to fetch.
|     (dolist (arts (gnus-info-marks (gnus-get-info group)))
|       (setq articles (gnus-union (gnus-uncompress-sequence (cdr arts))
| 			    articles)))
|     (setq articles (sort articles '<))
|
| ;;  ;; Remove known articles.
| ;;  (when (gnus-agent-load-alist group)
| ;;    (setq articles (gnus-sorted-intersection
| ;;		    articles
| ;;		    (gnus-uncompress-range
| ;;		     (cons (1+ (caar (last gnus-agent-article-alist)))
| ;;			   (cdr (gnus-active group)))))))
|     ;; Remove known articles, this is remove the `.agentview' articles
|     (when (gnus-agent-load-alist group)
|       (dolist (article gnus-agent-article-alist)
| 	(setq articles (delq (if (consp article) 
| 				 (car article) 
| 			       article)
| 			     articles)))
|       (message "Fetching missing headers... %s" articles))
|
| ...

This does the job. Nevertheless it tries to fetch unexisting articles
| (gnus-uncompress-ragne (gnus-active group))
is there a way to prevent this?

Furthermore it is difficult to find the fetched articles among the
already fetched articles since they are marked as read and maybe old.

Finally I think a command checking for missing articles is a good
idea. Is there something in Oort Gnus?

TIA, Micha

Some code related to the behavior has been rewritten in Oort Gnus.
