gnus-agent-fetch-session

[Miles Bader]

Is `gnus-agent-fetch-session' supposed to work (in Gnus 5.11)?

I tried marking a bunch of articles for download in a group, but having
gone online, can't figure out how to get them downloaded --
`gnus-agent-fetch-session' sits there and garbage collects for untold
ages (actually I killed it after about 5 min; no network activity at all
in that time).  `gnus-agent-summary-fetch-group' seem to start
downloading stuff but eventually got an error and stopped (I'll
investigate that later).

Thanks,

-Miles

Here's a backtrace from that error, btw (the command I typed was `J u'
in the *Summary ...* buffer):

   Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
     gnus-dup-unsuppress-article(1159457)
     gnus-mark-article-as-unread(1159457 32)
     gnus-summary-mark-article(1159457 32)
     gnus-agent-summary-fetch-group(nil)
     call-interactively(gnus-agent-summary-fetch-group)

The first line of `gnus-dup-unsuppress-article' is:

  (let ((id (mail-header-id (gnus-data-header (gnus-data-find article)))))

`article' is 1159457, and [with current buffer the *Summary...* buffer],
(gnus-data-find article) returns nil, which causes `gnus-data-header' to
return nil too, which `mail-header-id' barfs on...

Not sure what to do now...

Thanks,

I don't believe that I've ever tried the
gnus-agent-summary-fetch-group command.

Normally, when in a group buffer, I either process mark (#) the
articles then use gnus-agent-summary-fetch-series or I agent mark (@)
then use gnus-agent-fetch-group.

The gnus-agent-fetch-session works fine here but it traverses every
agentized server.  I've never seen it hang but I have seen it take a
long time to fetch headers from all of my servers.

Hmmm, it shouldn't crash though, right ... :-)

I think gnus-agent-fetch-session seems most potentially convenient (I
don't want to have to remember which groups I've marked for downloading
messages in).

But as I noted in my previous message, it seems to not really work in
any sane way:  I waited over 5 minutes for it to do something, and it
just sat there garbage collecting, with _no_ network traffic at all;
maybe it's doing some n^4 calculation before downloading or something...
