bug#38382: 26.3; Message body not displayed after editing in rmail-mode

Emacs - Bugs mailing list

Steps to reproduce:
1. Send yourself a text/plain email that has no body and no MIME attachments.
2. In Rmail, retrieve the email, adding it to your Rmail file.
3. Hit "e" to edit the message that has no body.
4. Add a body to the message.
5. Hit C-c C-c to finish editing. The body text you just added disappears!

If you save the Rmail file, kill the buffer, and re-open the Rmail file, it
properly displays the added body of the message, so I think it's just an
issue with how the message is displayed. Maybe it needs to be re-parsed after
editing?

I cannot reproduce this.  I see the added body after "C-c C-c" (with
the current master branch of Emacs).

How did you "add the body", precisely?  Please show the exact text you
typed between 'e' and 'C-c C-c'.

(Sorry it has taken me a month to reply. December was hectic with all the
holidays.)

Well, maybe this is fixed in the current master branch of Emacs, but I can
reproduce it with Emacs 26.3 started with 'emacs -Q'.

After typing "e" in eithre the rmail-summary buffer or the rmail buffer, the
exact keypresses I type are:

M->

This is a test.

RET

C-c C-c

According to describe-key-briefly, M-> runs the command end-of-buffer when
editing a message in my rmail buffer. After hitting 'C-c C-c', boom goes the
dynamite, the text "This is a test." just disappears. If I kill the rmail
buffer and re-open it, I see "This is a test." So it's there. It's just not
visible after I finish editing. So I guess you could say it's cosmetic only,
but it's very confusing. Again, if the message already has a body, there is
no issue with editing it. I only see this problem with the message has no
body to start with and I add one. And "This is a test" can be any text
really.

Thanks,
Ed

I did exactly the same, using Emacs 26.3, and I cannot reproduce the
problem.  I do see the added body after "C-c C-c".  So, however
strange, there's something else at work here.

Just to be sure: this happens for you in "emacs -Q" as well, does it?

Yes. And I reconfirmed that right before I emailed yesterday. Do you have
messages before and after the message with no body in the Rmail file? My
testing does. I haven't actually tested it with it being the last message.
Maybe that's the difference?

Thanks,
Ed

Maybe.  In my case it was the last message in the mbox file.

Well, I just tested it with "emacs -Q" and an inbox in which the only
message in the mbox file had no body, and the body I added when editing still
disappeared.

So, since you can't reproduce it, I think we can assume it's already fixed.
Feel free to close this issue.

Thanks,
Ed

Thanks, done.
