Agent strangeness

Agent strangeness

[Samuel Tardieu]

I have a server (nttp:news.ext.jussieu.fr) covered by the agent, and
all the groups that I take from this server also. If I fetch all the
articles (`g' then `J s'), then go offline (`J j'), and press `g'
again, I only see stars instead of article counts and Gnus tells me:

  Cannot request group comp.lang.ada: Opened server news.ext.jussieu.fr
  using directory ~/News/agent/nntp/news.ext.jussieu.fr/

I'm sure I've done something wrong :) But the directory exists... and
seems to have all the proper files in it (I'm using Quassia 0.27 btw).

(I forgot to say that the error message is when I try to enter a
"starred" group).

Btw, if I don't press `g' after getting offline, I can enter any group 
whose articles have been fetched by `J s' previously. Also, if I use
`gnus-unplugged', I get the same bogus behaviour (only stars for my
NNTP groups). It looks like the server is only half-covered by the
agent.

This has probably been fixed in 0.27, but you may see it for a while
yet.  The next time the Agent fetches somethign for these groups, it
should put it in the place nnagent expects to find it.

I have the same problem. I can't enter my Agen groups when Unplugged.

Same pb here...  0.27 was supposed to fix it, but AFAIK it is still here. Lars
is investigating it...

Well, it still doesn't with 0.29, and my bug report was already for
0.27... :(

prequel: I was having a problem with pgnus0.95/nnimap0.128 (NTEmacs
20.4) using the agent, that whenever I refreshed "g" the group buffer
unplugged, it would reset article counts to an old state instead of
the values I saw when working plugged.  I found that there was a
"groups" file in ~/News/agent/<<mailserver>>/agent.lib next to an
"active" file, which was the only candidate where gnus was getting
these old article counts from.  After renaming the groups file out of
the way, everything was fine.  So, I'm cross-posting this to ding to
find out whether I'm getting around the problem this the wrong way, or
the wrong way.. and hopefully find out the right way.

Indeed, but I only noticed it now I tried to reproduce the bug: once I
make groups available again in nnimap/<<mailserver>>/agent.lib I get
the wrong (old) counts after I press 'g' unplugged and after that lose
all the marks set in groups for articles which the "groups" file
didn't know existed.  (I'm guessing the marks are still there on the
server, checking)  Yes, the marks are still on the server, but got
misinterpreted/messed up while reading unplugged.  They are correctly
interpreted while plugged.

It seems an agent problem, because it seems to get more than a listing
of the groups from the "groups" file: initialising the active list and
using that one instead of the values in the "active" file.

Yes, I can reproduce it (see above).  And yes, it goes away after I
move "groups" out of the way.  In fact the "groups" file is never
touched or regenerated if existing.  Only "active" gets updated.
