Gnus capitalizes non-header "from"

Gnus capitalizes non-header "from"

[Christoph Groth]

[-- Attachment #1.1: Type: text/plain, Size: 631 bytes --]

Hi,

I regularly encounter a bug in Gnus (or message) that I'd love to fix.
Given my very rudimentary experience with Elisp, I'd very much
appreciate some help on how to get started.

The bug occurs when I send an email message with an attachment that is a
Python source file.  Lines in that file that begin with "from" (or
perhaps just the first such line), get capitalized, as if they were a
SMTP header.  For an example see the message [1] that I've just sent to
a mailing list.

How would one set out to debug this?

Thanks,
Christoph

Are you sure Gnus is the program mangling it? It is mangled in your
sent-folder?

I just tried emailing myself an attachment and "from" was untouched -
both in the copy in the sent-folder and the one I received through my
local Postfix. (I tried both with disposition=attachment and inline,
same result).

Let me try attaching it here, and we'll see what happens (maybe my email
gets rejected :-))


  Best regards,

    Adam

FWIW, I tried it, and the "from" was capitalized in both the received
and sent version.

Hm, interesting!

Difference in versions? In storage type?

(GNU Emacs 27.0.50 built from a7b7b85567f766ff510a5eaaaf32dbbbec15efd0,
nnml).

I would guess that storage formats that have more than one email per
file need to "escape" lines starting with "From " (as that is the
separator), and maybe something then happens to lines starting with
"from " as well?

If you view the raw article, what does the line look like then?

                                 o o o

Interestingly my attachment here was unmangled! What happens if you do a
similar attachment to your next follow-up here?

Thanks for your interest!

I did some more systematic tests.  The mangling is visible in the
locally saved version of the message, so it's definitely caused locally.
Moreover, the mangling seems to simply affect all the lines that begin
with a lower-case "from ", also in the main body.

The problem does *not* occur if I do not sign the message!  It *does*
occur when the message is signed either with an OpenPGP or with an
S/MIME key.

GNU Emacs 24.5.1 (x86_64-pc-linux-gnu, GTK+ Version 3.22.11) of
2017-09-12 on hullmann, modified by Debian

It's not a new problem, I remember seeing it for the first time years
ago.

It seems indeed have something to do with it, and not with SMTP headers.

I attach the pristine mbox file of a sent message (saved directly from
Gnus with 'o').  I only removed the host parts of email addresses.  The
MD5 sum of the attached file is ec7588fe8704b1d48aba09976894bc2e.

I am signing this mail, so let's see what will happen:
From this time forward, you will service us.

Aha. Maybe that is to avoid the lines starting with "[Ff]rom " being
(potentially) mangled after signing, leaving the signature invalid.

Yeah, mbox has used "From " as the separator for decades.

My setup is similar to Eric's.  I use nnimap and the backend is a local
dovecot that is synchronized (but that doesn't matter here) using isync.

Maybe... In order to debug this, it would be useful to examine the
various steps that lie between pressing C-c C-c and storing the
message.  Is "Edebug" the way to go?

edebug-defun is my go-to (but I am no expert in the topic :-))

What I would do is first find the chain of function calls that sends a
message, and then pick a likely one for edebugging. I started looking at
this yesterday: I thought `message-fix-before-sending' sounded a likely
culprit, but it wasn't to blame. That's as far as I got.

GNU Emacs 27.0.50 (build 5, x86_64-pc-linux-gnu, GTK+ Version 3.22.25)
of 2017-11-09

And dovecot IMAP, unfortunately, which rules out old storage formats.

Unless I'm doing something else wrong -- I'll have time to check this
out in detail tonight.

(Without having gone through your testing, and not knowing to which
detail you're familiar with the mail standards, so please excuse is this
is too basic:)

This can possibly boil down to the old e-mail standard for the "mailbox"
format - the old local storage format for incoming mail to a user
(typically in /var/(spool/)mail/liman (in my case). In those files,
messages are separated by a "From ...." line (no colon! not header!),
and in order to not mistake a text line starting with "From " for a
message separator, all "From " lines in a message had to be "quoted",
typically with a ">" leading to text like this:

   text text text text text text text text text text 
   text text text text text text text text text text 

   >From this day on, I had to write everything using the
   Comic Sans font, and I was very upset with my editor ...

Mail user agents typically convert this back to "From ..." when showing
a message, but as you undoubtedly realise, there is ample room for
mistakes here. One bug is to also "quote" lower case "from ..." to
">from ..." or even ">From ...", and/or when converting back make
another mistake ">from ..." --> "From ...".

One way around this could be to see whether you can append your Python
code as something else than "text/plain", and have it encoded in
Quoted-Printable (or even BASE64), which ought to eliminate the
problem. (Q-P encoding would lead to "From ..." --> "=70rom ...", if I
remember the standard correctly, which I probably don't ;-).

Then again, I could be completely off here. I usuaslly am ... ;-)
