bug#16649: Right margin overflows on neighboring windows.

[E Sabof]

From emacs -Q, with version from trunk.

STEPS:

(set-window-margins nil (car (window-margins)) 30))
C-x 3

Resize, until the right window is smaller than the margin.

RESULT:

The right window's right fringe will be drawn on top of the left window's right margin.

Should be fixed now.  Though using such large margins surely means
asking for trouble.

Thanks, martin

Works indeed, thanks!

Sorry, the right fringe renders correctly, but the margin still overflows. Attached is a screenshot of magit-log, where this can be seen. Below is a test case.

Evgeni

(let ((ov (make-overlay (point-min) (point-max))))
  (overlay-put ov
               'before-string
               (propertize "o" 'display
                           (list '(margin right-margin)
                                 (propertize
                                  "Laetamur quis quam, aliqua nostrum."
                                  'face '(:background "yellow")
                                  ))))
  (set-window-margins nil (car (window-margins)) 30))

Could you please tell what exactly is wrong with display in the above
test case?  And what does "the margin overflows" mean?  Maybe I'm
blind, but I don't see anything wrong when I eval the above code.

As for the magit display, it is so loaded with stuff that it is hard
to even know where's the margin there.  So please tell where to look
and what is it that you think is wrong in that screenshot.

Thanks.

You have to do C-x 3 and enlarge one of the windows to see the effects.
There were plenty of them - mostly related to not returning the right
values via window box related functions.  I also now adjust the window
margins when a window gets to narrow because otherwise the redisplay
engine gets confused when inserting new text.  Still pretty toothless
when confronted with more drastic specifications but the best I came up
with so far.

I did, and still didn't see any problems.

Anyway, thanks for taking care of this.

Any mode that gets to these extreme situations should be shot through
the head.

On Windows, whose redisplay is sometimes better than GTK's ;-)

OK.  Please try again.
