Subject: bug#48229: 28.0.50; C-g leaves inactive minibuffer selected with pop-up-frames
Date: Tue, 04 May 2021 16:43:17 +0100	[thread overview]
Message-ID: <87zgxaqzca.fsf@tcd.ie> (raw)

[-- Attachment #1: Type: text/plain, Size: 278 bytes --]

With the tiling WM Xmonad (regardless of Lucid/GTK2/GTK3/PGTK toolkit),
in which new Emacs frames always receive focus by default:

0. emacs -Q
1. M-: (setq pop-up-frames 'graphic-only) RET
2. M-x TAB

This pops up and gives focus to a new frame with the *Completions*
buffer:

[-- Attachment #3: Type: text/plain, Size: 384 bytes --]


Ignore the missing scrollbar; that's a separate long-standing issue ;).

3. q

As part of another long-standing issue on Xmonad (I guess because it
doesn't really do invisibility/minimisation/what-have-you), this
actually retains the *Completions* frame (which is still highlighted as
focused by the WM), but now neither frame looks "active" (all three
visible cursors are hollow):

4. Close the *Completions* frame.  In Xmonad that's Mod-Shift-c by
   default.

The minibuffer of the original frame is now selected:

[-- Type: image/png, Size: 28750 bytes --]

[-- Attachment #7: Type: text/plain, Size: 56 bytes --]


5. C-g

This leaves the inactive minibuffer selected:


[-- Attachment #8: 5.png --]
[-- Type: image/png, Size: 27223 bytes --]

[-- Attachment #9: Type: text/plain, Size: 4194 bytes --]


I think this inconsistent state might be the cause of or related to some
harder-to-reproduce "attempted to do X in sole/inactive
(mini)buffer/window" (or something like that) errors down the line with
Ivy minibuffer completion.  They happen seemingly at random when exiting
the minibuffer, perhaps multiple times an hour in a busy editing
session.  Once a frame reaches this inactive-but-selected minibuffer
state, subsequent minibuffer sessions are often problematic, so my
workaround is to simply delete that frame and hope it doesn't reoccur
for a while.  One thing that feels like it reduced the frequency of
these issues was disabling winner-mode and using {next,previous}-buffer
instead, FWIW.

This has been happening for a while now, I guess since the recent
overhaul of minibuffer behaviour (which is why I'm CCing Alan).

OTOH I can reliably reproduce the narrower issue in this report, so let
me know if you'd like me to test anything.

Thanks,
