bug#11172: 24.0.95; mini-buffer contents is overwritten by output in echo-area

[Peter Dyballa]

Hello!

Here is a simple case, which also shows more than just an annoyance.

Launch just compiled GNU Emacs with -Q, execute in *scratch* buffer

	(add-hook 'dired-mode-hook 'auto-revert-mode) 

and open the recent buffer in dired. Just for fun type

	M-x compile RET

and add some (meaningless) text to the make command or overwrite it with ./configure <whatever>. Now contemplate a bit, do as if trying to invoke configure in the other shell, from which GNU Emacs 24.0.95 was launched, to get its options. But type instead

	touch something

Still wait a moment, look at the text in the mini-buffer – oh, it's gone! It might be substituted with something like

	Reverting buffer `emacs-24.0.94'.

And when you now go to the Help menu to check "Send Bug Report..." no "*unsent Mail ..." buffer will open but the text

	apply: Command attempted to use minibuffer while in minibuffer

will appear in mini-buffer/echo-area.


This can happen quite often, also when contemplating over a regexp, or find-grep, or whatever. It might be often easy to get back to the original state, by some cursor backward or forward movement, but it is annoying. IMO it's cleaner when GNU Emacs would wait a while before spitting out some message until I have finished editing in mini-buffer.

bug#11172: 24.0.95; mini-buffer contents is overwritten by output in echo-area

[Stefan Monnier]

Hmm... I can reproduce the problem in the following way:

   emacs -Q
   M-: (run-with-timer 5 nil (lambda () (message "hello"))) RET
   M-x

after 5 seconds the M-x prompt is replaced by "hello" and will only
return when you type something on the keyboard.

This seems to have been fixed by this commit on current master:

commit aa89c84e00d8dc85100e6fedab7631c415e6364d
Author: Juri Linkov <juri@linkov.net>
Date:   Wed Nov 27 01:43:49 2019 +0200

    message uses minibuffer-message in the active minibuffer (bug#17272 bug#19064)

I'm therefore closing this bug report now.  If that is incorrect, and
this is still an issue, please reply to this email (use "Reply to all"
in your email client) and we can reopen the bug report.

Best regards,
