bug#50224: 27.2; auto-save-visited-mode blanks out the echo area after 5 seconds

[meedstrom--- via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Hey heroes,

So this has been troubling me for years, I thought it was just a part of
how Emacs worked.  But it cannot be intended.  Often there are complex
prompts that take time to read, such what lsp-mode asks you upon
visiting a .sh buffer.  Then after 5 seconds, the prompt text
disappears, but the minibuffer is still active and awaiting your reply.

To test it:

- M-x auto-save-visited-mode
- edit any buffer
- eval (message "foo")
- wait 5 secs

You'll see "foo" disappear.

I could look at how to solve this, but I'd need guidance.  The mode
calls save-some-buffers after 5 idle seconds, and I thought we could
wrap it in a let-binding that sets save-silently to t.  But it still
blanks the echo area. I also tried wrapping it in Doom Emacs' extensive
'quiet!' macro, and it still blanks the echo area.  Is this misbehavior
on the part of save-some-buffers?

I cannot reproduce this, neither in Emacs 27.2 nor in the current Git
master.  I see some message flash momentarily after 5 sec, but then
"foo" gets restored.

I wonder what do you do differently to make Emacs behave like you say?

Thanks.

Yup.  I also get a flash of 

Saving file /tmp/foo...
Wrote /tmp/foo

but then "foo" reappears.

(This is with "emacs -Q" and the current Emacs 28.)

Is previously noted, this doesn't seem to be reproducible in a stock
Emacs (i.e., "emacs -Q"), so perhaps this is caused by something in your
configuration?  Can you reproduce the problem with "emacs -Q"?

Also note that messaging when there's an active minibuffer has been
changed in Emacs 28 so that it'll never overwrite the prompt (but
instead add a [message] to the end of the echo area).

Finally, note that you can set `set-message-function' to filter out any
messages that you don't want to have happen.

No problem; I'm closing this bug report, then.

[meedstrom--- via Bug reports for GNU Emacs, the Swiss army knife of text editors]

For the curious, we found the issue. It relates to a workaround for map-y-or-n-p behavior, at https://github.com/hlissner/emacs-solaire-mode/blob/030964f7c62696c8cfb29125df6e7649d2bf9aeb/solaire-mode.el#L516-L531
