From: "Farblos" <AKFKQU.9DF7RP <at> vodafonemail.de> To: bug-gnu-emacs <at> gnu.org Subject: 28.2; `x-focus-frame' causes spurious input events causes edebug not showing intermediate results Date: Sat, 14 Jan 2023 22:55:15 +0100
This is Emacs 28.2 from the Debian emacs-lucid package running on fvwm3
on Xorg. I guess that either the lucid toolkit or fvwm3 is part of the
problem here, since I cannot reproduce this on a gtk3 Emacs.
To demonstrate the problem:
emacs -Q
M-x find-function fundamental-mode RET
C-u C-M-x ; instrument function
C-x 4 b *Messages* RET ; show message buffer
C-x o
M-x fundamental-mode RET ; call function
Then step through function `fundamental-mode' in edebug using SPC.
While doing so I do not get the intermediate evaluation results
displayed, but rather only the message "Stop". My message buffer looks
like this after stepping through the function:
fundamental-mode
Stop
Result: nil
Stop
Stop
Result: nil
Stop
Meaning: These permanent "Stop" messages hide the intermediate
results. I haven't found much information on this on the net,
only the following thread on gnu.emacs.help:
https://groups.google.com/g/gnu.emacs.help/c/ojSN-PgNvxg
The cause seems to be the call to function `x-focus-frame' in
function `edebug--display-1':
(if (not (memq (framep (selected-frame)) '(nil t pc)))
(x-focus-frame (selected-frame)))
When I instrument that snippet to
(when (not (memq (framep (selected-frame)) '(nil t pc)))
(message "input-pending-pre: %S" (input-pending-p))
(x-focus-frame (selected-frame))
(message "input-pending-pst: %S" (input-pending-p)))
my message buffer looks like this instead:
fundamental-mode
input-pending-pre: t
input-pending-pst: t
Stop
input-pending-pre: nil
input-pending-pst: t
Result: nil
Stop
input-pending-pre: nil
input-pending-pst: t
Stop
input-pending-pre: nil
input-pending-pst: t
Result: nil
Stop
That spurious pending input caused by `x-focus-frame' triggers
the following snippet later in function `edebug--display-1':
(when (input-pending-p)
(setq edebug-stop t)
(setq edebug-execution-mode 'step) ; for `edebug-overlay-arrow'
(edebug-stop))
which causes the "Stop" messages.
The following hack works around the problem, at least most of the time,
as the exact behavior also seems to depend on timing:
(define-advice x-focus-frame (:after (&rest _dummy) emacs-fix)
"Discards any spurious input to avoid stop events in edebug."
(let ((backtrace-frame (backtrace-frame 1 'x-focus-frame)))
(when (and (listp backtrace-frame)
(eq (nth 1 backtrace-frame) 'edebug--display-1))
;; a little sleep seems to make work-around safer
(sleep-for 0 50)
(discard-input))))
If you cannot reproduce (which is rather likely) pls let me know what I
should do to follow up on this.

AFAIU, input-pending-p should filter out focus events, so I don't think I understand why you see this. Can you try this in Emacs 29 or the master branch of the Emacs Git repository, so we make sure this problem was not fixed already? If it still happens in those newer versions, maybe you can step with GDB through get_input_pending, when it's called from input-pending-p, and through readable_events called by get_input_pending, and see why focus events aren't filtered out?

I used printf debugging and, admittedly, even back in Emacs 27 for now,
since I have the Debian toolchain ready for that. I reduced the test
case to this:
(defun testcase ()
(interactive)
(message "pre: %S" (input-pending-p))
(x-focus-frame (selected-frame))
(sleep-for 0.5)
(message "pst: %S" (input-pending-p)))
The error ("pst: t") reproduces only after touching some part of the
modeline that provides a tooltip.
And the offending event that causes `input-pending-p' to become t is
*not* a focus event (I can see indeed these getting filtered in
readable_events) but rather a HELP_EVENT. So as soon as one has touched
the modeline, the call to `x-focus-frame' produces these HELP_EVENTS.
Does that ring a bell? Any new directions where I should look at?
I'll try setting up a build environment for a newer Emacs when I find
the time to do so.

Only after seeing that HELP_EVENT in Emacs 27 I understood that hovering over the modeline is a necessary precondition to reliably reproduce this issue. So without debugging in Emacs 27 I wouldn't have been able to ensure that the bug is gone in master ... Feel free to close this issue. Optionally: If you happen to have an explanation why this bug is gone, I'd really appreciate that. Thanks for developing Emacs!

Optionally: If you happen to have an > explanation why this bug is gone, I'd really appreciate that. I'm afraid I don't know what change fixed this, and the problem doesn't reproduce in my configuration, so I have difficulty trying this out in different versions to try to answer that question. So I'll just close the bug. Thanks for testing the current codebase.
