No Gnus don't get new articles after server change.

No Gnus don't get new articles after server change.

[Maciek Pasternacki]

I use No Gnus (CVS checkout now from a few days ago) on GNU Emacs 22
(fresh checkout too).  Some time ago my primary Usenet server crashed
and was reinstalled, and article numbers were lost.  From that time on
whatever I do with Gnus to rehash article numbers, it doesn't see new
articles when offline. I.e. I start up Gnus, see all groups on native
server caught up (no new articles) (on other NNTP servers I do see
other articles, so do I get mail via nnmail).  When after some time
I hit `g', Gnus gets new articles -- but only those that were sent
after Gnus was started.  I can use groups normally while Gnus is on;
then I quit Emacs and when I start Gnus again, there are no unread
articles on all native groups (even if I left some unread ones when
quitting Gnus -- those are caught-up too).

I tried all I could think of to re-initialize native server; I have
even gone to what I think is complete rehash:

 - un-agentize primary server (it might be some old agent files left
   over);
 - M-x gnus-agent-expire, and let it delete all files related to
   server;
 - M-x gnus-agent-regenerate, just in case;
 - M-x gnus-group-clear-data-on-native-groups, to make Gnus forget all
   numbers, marks and everything related to server;
 - catch-up (`c' from *Group* buffer) on all native groups;
 - agentize server again

Doesn't work too.  I still can't see new articles.  Any ideas what
might be wrong?

I've had similar problems lately, using a CVS snapshot from
2005.10.02.  I wiped my hard drive and reinstalled everything, saving
everything important from my homedir first, especially ~/News.  After
doing so, none of my gmane groups were showing new messages as unread,
though I could still browse them.

Adding (nntp-marks-is-evil t) to the options for gnus-select-method
seems to make things work.  I had tried moving my ~/News/marks folder
somewhere else, but this caused Gnus to throw the following error when
starting up.

Thanks, it helped -- I didn't think of moving marks away.  After
investigating contents of .marks files I managed to clear them all:

 $ echo '((read))' > foo ; find ~/News/marks/news.task.gda.pl -name .marks -exec dd if=foo of={} \; -print

(news.task.gda.pl is name of my server).

Shouldn't gnus-group-clear-data clear marks files too?

Marks files and gnus-group-clear-data (was: No Gnus don't get new articles after server change.)

It should.  And it does it in my tests:

$ cat News/marks/localhost/de/comp/advocacy/.marks
((tick 310) (read (1 . 310)))

`M-x gnus-group-clear-data-on-native-groups RET' in fact calls
`nntp-request-set-mark'...

$ cat News/marks/localhost/de/comp/advocacy/.marks
nil

Note that you must *not* set `nntp-marks-is-evil' to t when clearing
the data.

Bye, Reiner.
