Subject: Cancelling a new mail in message-mode ignores rmail-mail-new-frame
Date: Sat, 18 Feb 2012 17:02:37 -0500

Package: emacs
Version: 24.0.93
Severity: minor

emacs -Q \
  --eval "(setq rmail-mail-new-frame t mail-user-agent 'sendmail-user-agent)"
M-x rmail
m
  -> new frame appears for mail composition
Choose Mail menu, Cancel
  -> frame disappears

repeat with the default message-user-agent:

Choose Message menu, Kill Message
   -> frame does not disappear


If you fix this, you can restore (a suitably modified version of) this
commented-out text in rmail.texi:

@ignore
@c FIXME does not work with Message -> Kill Message
, or when you use the @samp{Cancel} item in the @samp{Mail} menu.
@end ignore

This is an rmail bug and not a Message bug, I guess?

I don't really see how it could be. At first glance, it seems that
message-kill-buffer does not run message-bury, and hence does not
process the return-action of compose-mail. Compare with
message-dont-send, which does delete the frame.

I see.  Well, I don't use either rmail nor use pop-up frames, so I'm
probably the wrong person to try to fix this.  Unless absolutely nobody
else can, that is...

And it should disappear, so that's the bug?  What command does that
"Cancel" menu run?

message-dont-send is return-action, which is documented as

---
RETURN-ACTION, if non-nil, is an action for returning to the
caller.  It has the form (FUNCTION . ARGS).  The function is
called after the mail has been sent or put aside, and the mail
buffer buried.
---

message-kill-buffer isn't what's meant by return-action in the
compose-mail interface, I think?

I don't know how to explain it any better than in the OP.
The intent of the Rmail code is that discarding a draft should delete
the frame. It works with mail mode but not message mode.

Message has two ways of returning to the caller (while not sending
anything).  message-dont-send runs RETURN-ACTION (which is presumably
what Rmail uses to close the frame etc), while message-kill-buffer does
not run RETURN-ACTION.

I don't see how to reconcile that on the Message side.

Rmail could set message-kill-actions to whatever it wants, which is why
I think this is an Rmail bug.
