bug#7287: 24.0.50; epa

[Richard Stallman]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

With Epa Mail mode, after C-c C-e d, the buffer with the
decrypted message seems to be in Info mode.  That is not helpful.
mailcrypt-decrypt puts the decrypted buffer in Rmail mode
(at least when coming from Rmail mode), and that's what
Epa Mail mode should do.

Ideally it should use whatever mode the user was using
for the buffer that has the message, and it should copy
the parts of the buffer that didn't need decryption.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/home/rms/emacs-bzr/trunk/etc/DEBUG.

Do you still see this bug?  If so, do you have a recipe for how to
reproduce this bug?

I have forgotten how to use Epa Mail mode.  Can you tell me how?

No, that's what I was hoping you could tell me so that I could try to
debug it.  :-)

But if somebody else knows how to, please jump in.

I think epa-mail-decrypt is either obsolete, or strongly deprecated,
since everyone should be use message mode with mml tags to get proper
MIME formatting, but hereʼs what I tried:

    Sent myself a message with inline OPENPGP
    Opened that with Gnus
    Told Gnus to *not* automatically decrypt the OPENPGP part :-)
    K-c to get a buffer with the encrypted text
    M-x epa-mail-mode
    C-c C-e C-d

The end result was a buffer called '*decoded*' in fundamental mode,
which is the same mode as what K-c used.

I think you can close this bug.

Thanks for the recipe.

I'm getting a different result -- after answering `n' to the question

Replace the original text? (y or n)

I get a buffer called " *Temp*" which is, indeed, in a buffer that say's
it's Info mode.  Looking at the code, it's:

(defun epa-decrypt-region (start end &optional make-buffer-function)
  "Decrypt the current region between START and END.

[...]

	  (with-output-to-temp-buffer "*Temp*"
	    (set-buffer standard-output)
	    (insert plain)
	    (epa-info-mode))))

And that mode is:

(define-derived-mode epa-info-mode special-mode "Info"
  "Major mode for `epa-info-buffer'."
  (buffer-disable-undo)
  (setq truncate-lines t
	buffer-read-only t))

So I think the fix here is just to change the lighter to "EPA Info" to
avoid this confusion.

I'm doing that and closing this bug report.

How does "Epa Mail mode" relate to epa-mail-decrypt?
Are they the same thing?  Related?

I don't think I ever use "Epa Mail mode", but I depend on
epa-mail-decrypt to find and decrypt mime parts in Rmail.
It is called by rmail-epa-decrypt in rmail.el.

The Epa Mail mode has a key binding for the epa-mail-decrypt command.

I see.  I just made my own key binding for this.
