nnvirtual problem

[-- Attachment #1: Type: text/plain, Size: 671 bytes --]

Hello,
Since I just advocated using nnvirtual, I thought I'd give it a go.  I
created a new virtual group (G V) and then customized its select
method to be (nnvirtual "^nnfolder"), which I though would be quite
fun as it would then *all* my mail.

It looked like everything was working nicely.  It took about 20
seconds to open the group with about 10MB in c.1000 messages and I
played around to see what I could do.  I tried to see if I could use
it as a poor-man's search engine, and I could, with M-s, then I tried
to leave the group (by pressing 'q') and it started trying to expire
various articles, and I got;
(wrong-type-argument listp 240)

Here's the backtrace:

It had been fixed in 2000-11-05.

It looks something wrong with sort. Could you evaluate the following
in your version of Emacs, i.e. Emacs 20.3?

(sort '(963 965 970 981 986 993 995 997 1002 1013 1018 1025 1032 1037

No error, just:

I had similar problems with calls to sort a long time ago, and this
was the exchange that led Lars to a fix.  Hopefully the same kind
of fix will work here.

I've been putting off changing nntp servers for a few months, but now I've
got only 7 days before I lose access to old news server.  However,
gnus-change-server is still giving me problems, with qgnus 0.14 and
emacs 19.34.1.  This has been discussed before, but below there's
something that might provide a hint.  Here's a backtrace:

Signaling: (wrong-type-argument number-or-marker-p nil)

* call-interactively(gnus-change-server)
  execute-extended-command(nil)
  call-interactively(execute-extended-command)

If I execute (sort '(nil) '<), emacs successfully returns (nil).
However, if I execute (sort '(nil nil) '<), emacs complains and gives
me the following backtrace, which looks suspiciously like the above
backtrace.

Signaling: (wrong-type-argument number-or-marker-p nil)
  <(nil nil)
  sort((nil) <)
  eval((sort (quote (nil)) (quote <)))
  eval-expression((sort (quote (nil)) (quote <)))
  call-interactively(eval-expression)

Could gnus be trying to sort a list like (nil nil)?  (And can anyone
explain why in the backtrace it says sort((nil) <) rather than
sort((nil nil) <)?)

There is something odd about sort.  It sometimes works, and sometimes
it doesn't.

No.

hmm.  that's the only way I can get this failure in
emacs-20.2.  the backtrace is a little misleading though.

    (sort '(nil nil nil nil nil) '<)

      <(nil nil)
      sort((nil) <)
      eval((sort (quote (nil)) (quote <)))

It all makes sense now.  The backtrace is FUBAR because `sort' changes 
its first argument destructively!

Ah!  It all makes sense now.

One more of life's big mysteries solved.  I'll slap some `(delq nil ...)'
around some lists that I feed to sort, and Bob's your uncle.
(Whatever that means.)

Ahh, thanks.  Can anyone tell me how to figure out which instance of
sort is causing the problem.  My edebug skills are nil.

Oh, that's clever - the backtrace tells us from which function sort
was called.
