gnus-summary-edit-article and wrapped From-line

gnus-summary-edit-article and wrapped From-line

[Reiner Steib]

Hi!

Given the following article (a minimal example):

,----[ cat Incoming13789n9p ]
| From MAILER-DAEMON@aaaaaaa.bbbbbb.ccccccc.dd  Thu Aug 30 19:30:14 2001
| Subject: long From-line
| 
| foo bar
| 
`----

When I hit »e« (gnus-summary-edit-article) in the *Summary* buffer to
edit the article and save the article with C-c C-c, the From-line is
wrapped (this also happens after stripping an attachment with
»Save and strip«):

,----[ cat mail/test ]
| From MAILER-DAEMON@aaaaaaa.bbbbbb.ccccccc.dd  Thu Aug 30 19:30:14
|  2001
| X-Gnus-Mail-Source: file:/var/mail/guest
| Message-ID: <sa6sne9mheg.fsf@totally-fudged-out-message-id>
| Subject: long From-line
| Xref: ni.physik.uni-ulm.de mail.test:5
| Lines: 2
| X-Gnus-Article-Number: 5   Thu Aug 30 22:17:54 2001
| MIME-Version: 1.0
| Content-Type: text/plain; charset=us-ascii
| 
| foo bar
| 
`----

The problem with this is, that nnfolder doesn't recognize this article
anymore (so does the frm(1) command). If I repair the From-line, I can
select the article again.

I'm using Gnus/5.090004 (Oort Gnus v0.04) Emacs/20.7 (cvs version of
Gnus from 2001-08-03 but also happens with latest cvs version:
2001-08-31 15:37:41 CEST 2001). It doesn't happen with Gnus v5.8.8
(same Emacs version).

Is this an error in the nnfolder backend (recognizing the wrapped
From-line)? Or is gnus-article-edit-mode doing something wrong? BTW,
in the *Article* buffer, auto-fill-mode is _not_ active. The wrapping
happens _after_ I hit C-c C-c.

Reiner.

P.S.:

In my (test-) ~/.gnus.el I only set gnus-[secondary-]select-methods
and I started emacs with »--no-site-file« and in my ~/.emacs I only
set the load-path for Gnus, nothing else.

Do you have any weird auto-line-wrapping going on?

No, I don't think so, because I used "emacs --no-site-file" and
minimal init files (see below / attached user settings).

I just reproduced it with both, GNU Emacs 20.7.1 and GNU Emacs 21.1.1,
with a very recent CVS version of Gnus (Sun Dec 30 15:33:08 CET 2001).
The bug does *not* appear with Gnus v5.9.0 (GNU Emacs 21.1.1) or Gnus
v5.8.8 (GNU Emacs 20.7.1).

Here's the content of ~/.emacs and ~/.gnus:

##### ~/.emacs

Right.  Well, I don't have any nnfolder groups handy -- could someone
who uses nnfolder have a peek at this problem as see what they cause
is?

(The problem is that `e' on the article creates a buggy "From " line.
I didn't think the "From " line would be included in the `e' output at
all...)

The attached `patch' prevents the folding of the From-line (simply
skip rfc2047-fold-region in lisp/rfc2047.el after
  `;; No encoding necessary, but folding is nice').

Maybe folding isn't so nice after all. :-/ At least the From-line
shouldn't be folded, AFAICS.

Could you say `M-x debug-on-entry RET rfc2047-encode-message-header RET'
and then edit a message?  It doesn't seem to be called for me, and
I want to see who the caller is.

How come you get a "From " line when you `e' the message, anyhow?  I
don't get that -- I get an "X-From-Line".

yes, in the Article buffer (and in the buffer for editing) the line is
displayed as `X-From-Line: ...' but on disk it is saved as `From ...'.
The backend is nnfolder, so each article _must_ have a `From ...'
line, as nnfolder is standard Unix mbox format (plus extra headers).

Right.  I've now looked at the code in nnfolder for accepting
articles, and I've made it unfold the X-From-Line header if it's
there.

I'm unable to reproduce this bug.  Could someone else see whether they
can?

(The bug is that if you `e' an nnfolder message, and fold the
X-From-Header, then the resulting "From " mail header separator won't
be unfolded.)

Looking at the logs, it was rejected because I inserted a To header,

Anyway, I've now had the posting script rename To to Original-To.
