Yes, that fixes the problem.  I'll push the corresponding fix to the
custom widget code, and I'm closing this bug.  Thanks.

It was a subtle bug in how we handle face's box attribute when the
display engine changes the object on which it iterates.  Compare the
effect of this:

  (with-current-buffer (get-buffer-create "*test*")
    (load "wid-edit")
    (load "cus-edit")
    (insert #("foo\nfoo" 0 4 (face widget-field)))
    (let ((overlay (make-overlay 5 8 nil t nil)))
      (overlay-put overlay 'before-string "X")
      (overlay-put overlay 'face custom-button)))

with this:

  (with-current-buffer (get-buffer-create "*test*")
    (load "wid-edit")
    (load "cus-edit")
    (insert #("foo\nXfoo" 0 4 (face widget-field)))
    (let ((overlay (make-overlay 6 9 nil t nil)))
      (overlay-put overlay 'face custom-button)))

The change of face between the "X" and the following button should be
displayed the same, but wasn't.

I installed a fix on master.  Please see if it solves the real-life
use case, and close the bug if it does.

Thanks.

It shouldn't insert anything except for the text of the button itself --
for one, the invisible character won't end up in the kill ring when you
try to save the button text.

There are also various assumptions made all over the place about the
position of a button and the length of the text in the buffer, and I'm
not confident I can fix them all.

So make an overlay whose property is 'invisible' -- doesn't that work?

What do you mean by "wid-insert might not be able to insert" -- isn't
the text of the button inserted as well? then why not make the
invisible character part of the inserted button text?

It has to be an overlay, because wid-insert might not be able to insert
such a character before the button.  (In general, the display of
everything in a button except for text seems to be done entirely with
overlays -- I don't think the buffer is supposed to contain anything
other than the text of the button itself.)

I hope this helps:

  (with-current-buffer (get-buffer-create "*test*")
    (insert #("foo\nfoo" 0 4 (face widget-field)))
    (let ((overlay (make-overlay 5 8 nil t nil)))
      (overlay-put overlay 'before-string (propertize " " 'invisible t))
      (overlay-put overlay 'face custom-button)))

After this, I would have expected the second "foo" in *test* to begin
with a box line, but it doesn't.

Thanks in advance.

Why did you want to use a before-string? why not simply a single
invisible character before the button?  It sounds like an unnecessary
complication to me, since before-strings and after-strings are
inherently tricky, even when they aren't invisible.

But if you want me to look into this, you know what to do: show me a
short Lisp recipe which I could investigate.

I found another potential problem: determining the start of a box run
doesn't take the before-string of an overlay into account.

wid-edit.el displays the button face through an overlay spanning from
the start to the end of the button, and I wanted to solve this problem
by adding a before-string containing a single invisible space, but that
doesn't seem to be affecting the non-display of the button's left box
line.

Any ideas?  Thanks in advance.

I think it might be easier to use invisible text, assuming it does the
job.  For example, try this slightly modified variant of your recipe,
to see what I mean:

 (insert #("foo\n foo " 0 4 (face widget-field) 4 5 (invisible t) 5 8 (face custom-button)))

Thanks for the explanation, it was very helpful.  Maybe it would work to
put some kind of zero-width character with no face between the start of
the line and the INS buttons?

I don't think this is right.  At the very least, it will change a
long-standing behavior: we don't set the start_of_box_run flag just
because we found a different face.  Instead, the entire run of
characters whose face(s) have the :box attribute set will appear as a
single box, with a single start at the beginning and a single end at
the end of the run.

Drawing a beginning of a new box each time we find a new face is
certainly not what's expected: the most striking example of that is
the mode line: it could have different strings with different faces,
but we want only one start_of_box_run and only one end_of_box_run_p:
at the very left and the very right, respectively.

Even if you suggest to limit this to a new face that happens to begin
at the start of a new line, I still don't think this is TRT: why is a
new line special for this purpose?  If the newline before it had the
:box attribute set in its face, the character after the newline is
just the continuation of the same run of characters that started on
the previous line.  We shouldn't handle this specially when the :box
attribute crosses a newline.

So I see no bug in how the display code works in this case.

It does update it->face_id, just not where you expected it to.  See
below.

No, set_iterator_to_next called with RESEAT non-zero only calls reseat
if it skips some text, e.g., due to invisibility.  If it just moves
from a newline to the first character of the next line, it doesn't
call reseat, because there's no need to do so: reseat is for when we
need to move the iterator non-linearly, or jump over several character
positions.

No, this is not needed.  handle_face_prop will be called once
display_line continues walking the buffer and processes the first
character of the new line.  At that time, it will notice that it
overstepped the stop position, and will call handle_stop, which will
call handle_face_prop, as expected.

You expected it to be called when processing the newline, but that is
too early.

But once again, I don't see anything that needs to be fixed in the
display engine.  Perhaps we need to rethink how the Lisp code sets up
the buttons as regards to the various faces or something.  IOW, let's
have a look at how the faces are set on the text in that case, and see
why we end up with two consecutive faces each one with a :box
attribute, because this has got to trigger this behavior, which you
find surprising and possibly incorrect.  The question is: can we
achieve whatever effect we wanted with the :box attributes without
losing the button appearance in the process by changing the Lisp code
there.

Causing widget-field to have a box (which gets extended to the end of
the line) makes the custom button on the next line lose its start box
line, so it's not the other way around.

The code that added a box to widget-field.  But it seems that Stefan
suggested to disable it, and you only happened to concur.

Maybe this will help jog your memory (but you really ought to look at
the whole bug report.)

The other way around, I guess?

Or maybe I don't understand what you mean by "box"?

Which buggy code was that, and where did I suggest disabling it?

Yes, widget-field has a box on master, while it doesn't on emacs-28.  In
fact, it was you who suggested disabling the buggy code on Emacs 28 :)

I didn't yet look seriously enough at that, but: I can only reproduce
this problem on the master branch; Emacs 28 works as expected.  Is
that what you see as well?  If so, then it is strange that you think
the problem happens in the code that wasn't touched at all between
Emacs 28 and Emacs 29, AFAICT.  Most probably, the root cause is
somewhere else.

I have this code mostly working now, but I don't understand why
set_iterator_to_next doesn't seem to be updating it->face_id.

AFAIU, set_iterator_to_next called with RESEAT set to true eventually
calls reseat, which in turn calls handle_face_prop through handle_stop
if the iterator was reseated past the stop position, which should be set
to the beginning of the next line when the face property at that next
line differs from the line whose face is being extended.

However, handle_face_prop is never called, so I have to call it manually
like this:

	  /* Consume the line end.  This skips over invisible lines.  */
	  set_iterator_to_next (it, true);

-->	  handle_face_prop (it);
	  if (it->face_id != DEFAULT_FACE_ID
	      && it->face_id != saved_face_id)
	    {
	      face = FACE_FROM_ID_OR_NULL (it->f, it->face_id);
	      if (face && face->box != FACE_NO_BOX)
		{
		  it->face_box_p = true;
		  it->start_of_box_run_p = true;
		}
	    }

Any ideas?  Thanks.

I think I found the bug, it's in display_line.

When the label at_end_of_line is reached, it->start_of_box_run_p can be
false.

Afterwards, set_iterator_to_next is called, which reseats the iterator
to the next line, but doesn't set it->start_of_box_run_p if the face is
now different from the previous face and also has a box.

I think the solution is to save the face ID of the iterator after the
call to extend_face_to_end_of_line, then compare it to the face after
the iterator is reseated to the next line, and set
it->start_of_box_run_p to true if that face is different and also has a
box.

WDYT?

I don't know, the arrangement of faces on that button is complicated,
to say the least.  I don't think I even understand which parts of the
display is the widget-field face applied to.  Can you show the
complete definition of the button face at the first line and the
non-first line?

Yes, I think we should do that.

Thanks.

It seems like the entire line is shifted a pixel to the left when using
:box, but only on the second consecutive line.  I tried experimenting
with :box 1, :box -1, and I get the same result.

Are we sure that's not a bug in the display code?

In any case, we could revert the commit for emacs-28 and continue investigating
on master.

Thanks, I'll bisect when I get the time.  But you have got one minor

in the buttons that don't.

With the following patch I no longer see the display glitch:

However, this cannot be the right fix: with this patch the editable
field widget is no longer editable (it also doesnt't extended to the
right window margin, and it's one space shorter than when the
widget-field face is edited to remove the :extend property (without the
patch)).  Moreover, in emacs-27 the editable field is also extended yet
there's no display glitch.  (There's one difference in
widget-specify-field between emacs-27 and 28/master, but undoing that
change in the latter does not eliminate the display glitch.)

There's also something strange about customizing the widget-field face:
when I uncheck the box for "Extend" and click the "State" button to "Set
for Current Session", nothing happens with -Q and without -Q I get the
message "End of file during parsing".  If (without -Q) I click "State"
to "Save for Future Sessions", then it says "SAVED and set" but the
"Extend" checkbox remains checked and the editable fields are extended.
If I keep "Extend" checked and click the Value Menu to "Off", then I can
set the change for the current session, and then the editable field
widget is not extended, but the display glitch remains (and the editable
field is one space longer than with the above patch).

That isn't related, it only serves to make buttons look nicer and have
more contrast by drawing a black line outside a relief rect.

FWIW, this bug doesn't manifest in 27.2.

According to this screenshot, the problematic button is the first one,
because on my system the first one doesn't have the left and the top
border lines, and neither do all the rest.

I see that xterm does something special in x_draw_relief_rect when the
line width is exactly 1 pixel, and w32term.c doesn't do that.  maybe
that's the problem.

I cannot reproduce this.  Maybe this is specific to GTK?

Run emacs -Q.  Do M-x customize-group RET files RET, expand "After Save
Hook", then click "INS" twice.  The second INS button will not have a
left box line, which is visually inconsistent with the first, and with
how buttons work in general across all X-Windows applications.

The repository branch used is not relevant here, it can also be
reproduced in master and emacs-28.

Thanks.
