To: 25645
I'm using message.el in conjunction with mu4e, which uses Fcc and a
message-fcc-handler-function to save the outgoing message directly into
a maildir folder. Nothing fancy: Fcc is set via a message-send-hook,
then in the handler we just 'write-file and some bookeeping.
It works as expected with emacs 25.2, but fails on 26 when the body
contains unicode characters. Somehow when the mail is encoded in quoted
printable with an utf-8 charset, the buffer seem to contain raw bytes as
if the buffer has an incorrect buffer-file-coding-system.
When 'write-file is issued, emacs prompts for a coding system, which is
unexpected.
The stack is as follows:
read-from-minibuffer("Select coding system (default raw-text): " nil (keymap (10 . minibuffer-complete-and-exit) (13 . minibuffer-complete-and-exit) keymap (menu-bar keymap (minibuf "Minibuf" keymap (tab menu-item "Complete" minibuffer-complete :help "Complete as far as possible") (space menu-item "Complete Word" minibuffer-complete-word :help "Complete at most one word") (63 menu-item "List Completions" minibuffer-completion-help :help "Display all possible completions") "Minibuf")) (27 keymap (118 . switch-to-completions)) (prior . switch-to-completions) (63 . minibuffer-completion-help) (32 . minibuffer-complete-word) (9 . minibuffer-complete) keymap (menu-bar keymap (minibuf "Minibuf" keymap (previous menu-item "Previous History Item" previous-history-element :help "Put previous minibuffer history element in the minibuffer") (next menu-item "Next History Item" next-history-element :help "Put next minibuffer history element in the minibuffer") (isearch-backward menu-item "Isearch History Backward" isearch-backward :help "Incrementally search minibuffer history backward") (isearch-forward menu-item "Isearch History Forward" isearch-forward :help "Incrementally search minibuffer history forward") (return menu-item "Enter" exit-minibuffer :key-sequence "

Note that in the body of the handler I currently have:

The no-coding-system-for-write is just for debugging (setting
coding-system-for-write to 'raw-text fixes the issue). I don't expect
the handler to have to set it explicitly though.

Buffer contents is entirely unrelated to the value of
buffer-file-coding-system. The latter only determines how to encode
the buffer contents when writing it to a file or sending it to another
process or network connection.
If you get raw bytes in the buffer, the culprit is in the code which
inserted those bytes, or read them from some file.

This is expected when there are raw bytes in the buffer. The problem
is elsewhere.

Yes, the content of the buffer is generated by
message-encode-message-body in message.el itself.
You only need to insert an unicode letter in the message's buffer to
trigger the issue when recoding to qp-utf8.
I wrote to Lars prior to filing this report (cc-ed).

Since the fcc-handler is expected to do something with the buffer (write
it out), I expect message.el to preset the buffer coding system if the
buffer becomes unibyte in nature.

I'm unable to reproduce the error, and I don't think it should block the
release, since it doesn't seem to affect many people.

In addition to myself, at least several other mu4e users seem to
have
been affected by this:
https://groups.google.com/forum/#!topic/mu-discuss/dIj3W_R-M4A
https://groups.google.com/forum/#!topic/mu-discuss/NJgRONE7Xuk
https://groups.google.com/forum/#!topic/mu-discuss/MaYcS5uRcsM
https://groups.google.com/forum/#!topic/mu-discuss/RC1Scq2wCe4
and maybe:
https://groups.google.com/forum/#!topic/mu-discuss/dxfpdcidtoc
i've not yet been able to consistently reproduce it, so haven't
yet been
able to narrow down whether the issue is with mu4e or with
Emacs. (Maybe
something has changed in Emacs that mu4e needs to become aware
of). i'll
try to work on this as soon as i can, unless Yuri is able to
produce an
MRE first. :-)

I didn't find the time yet. I wanted to make a minimal test case using
only message-mode.

I'm unable to reproduce this bug. If I put
Fcc: /tmp/fcc
in my headers and enter text like "föo" in the body, the file is saved
as it should be.
Could the problem be in your handler?

Adding an Fcc is not enough, if you read the initial report, the issue
is triggered by attempting to call write-file within a
message-fcc-handler-function.

Do you have a minimal recipe that demonstrates the bug?

My minimal recipe still involves using mu4e at the moment.
I can try to make a self-contained test case, but I might need a couple
of days.

Does this count as a reproducer?
(defun bug-25645-reproducer ()
"Reproducer."
(let ((buf (get-buffer-create "*bug25645*")))
(switch-to-buffer buf)
(message-mode)
(goto-char (point-max))
(insert "\né")
(with-temp-buffer
(insert-buffer-substring buf)
(message-clone-locals buf)
(message-encode-message-body)
(get-buffer-create "*bug2564-copy*")
(copy-to-buffer "*bug2564-copy*" (point-min) (point-max)))))
Certainly if I comment out the (message-clone-locals) in message-do-fcc
behaviour reverts to pre-emacs26.

It does, but since you have already established that
message-clone-locals is the culprit, the next question is: what is the
exact list of local variables that gets cloned here? Can you post the
full list?
Thanks.

Ahh sorry I thought debbugs would munge an appropriate subject when it

Sure. From my message log, it seems we clone locals for that buffer at
least twice:

A stab in the dark: what if you filter out message-default-charset
from the cloned locals?

Good guess:
(defun message-clone-locals (buffer &optional varstr)
"Clone the local variables from BUFFER to the current buffer."
(message "message-clone-locals: %s" buffer)
(let ((locals (with-current-buffer buffer (buffer-local-variables)))
(regexp "^gnus\\|^nn\\|^message\\|^sendmail\\|^smtp\\|^user-mail-address"))
(mapcar
(lambda (local)
(when (and (consp local)
(car local)
(string-match regexp (symbol-name (car local)))
(or (null varstr)
(string-match varstr (symbol-name (car local)))))
(ignore-errors
(unless (string-match "message-default-charset" (symbol-name (car local)))
(message "copying: %s -> %s" (car local) (cdr local))
(set (make-local-variable (car local))
(cdr local))))))
locals)))
Although I feel a slightly neater solution is needed.
So is the problem we are attempting to double encode an already encoded
buffer or something else?

Hmm... what is non-neat about this one? The existing filtering
already includes quite a bit of ad-hoc'ery.

Something like that. I could look deeper, if needed, but frankly the
thick forest of Gnus encoding-related stuff is not something I like to
wander into. It's easy to break things there because effects are not
localized.
Thanks.

Thanks, I installed this, and I'm marking the bug done.
