Bug sending messages unplugged

Bug sending messages unplugged

[Markus Dickebohm]

I get the following backtrace while sending queued messages ("J S")
with pgnus-0.53 (this is with XEmacs-20.4-non-mule):

Signaling: (wrong-type-argument integer-or-marker-p nil)
  lazy-shot-fontify-internal(#<buffer "*sent mail*<2>"> nil nil nil "")
  lazy-shot-lock-extent(#<destroyed extent> nil)
  lazy-shot-redisplay-function(#<destroyed extent>)

As far as I can see, the messages aren't sent although they disappear
from the "nndraft:queue"-group.

This is very weird.  Is this the entire stack trace?  It seems a
little truncated.

Yes it is, actually.  I get them too.  The odd thing is that I only
get them when sending news, not mail.

Anyway, I think what is happening is that gnus places the articles in
a new buffer (*mail* oddly enough, since its news) and then font lock
is swinging on them after that.  What I'm not sure of is if its
happening before or after the article gets sent.  I think its before
(which is bad) not after (which would be bad for me, because it means
I've sent multiple copies of messages to my newserver because of the
above bug).

I submitted a bug report to Lars, and he said its lazy-shot's fault
and I should submit the bug to that author instead.  I didn't want to
do that until determining the exact "fault" first, since I suspect
they'd say its was Gnus' fault.

It is too late now. I have seen it :-)

It is indeed a Lazy-shot bug. It is fixed in 21.0. Gnus is probably
copying parts of the buffer around into strings and lazy-shot does not
like that very much. However this is also a good indication Gnus is
using buffer-substring somewhere where it probably needs
buffer-substring-noproperties.

Cool! Thanks for the patch!

I reproduced the bug and now I get:

This isn't the case here. I tried mail and news but in any case only
when sending MIME-Mails the error gets triggered.

My tests revealed another bug in respect to news postings:
 two Content-Type headers are generated when sending queued postings
 and my articles were rejected by the newsserver.

I saw this when re-posting the articles that died from the previous
error.  Mainly because I was submitting them with C-c C-c from the
mail buffer they died in, which caused the headers to get inserted a
second time.  Gnus should, though, remove the old headers before
recreating new ones.

If lazy-shot is running off of after-change-hooks (or the like), you'd 
get a backtrace this short when it fails.
