bug#18437: 24.3.93; cursor changes color and size at end of line

[David Reitter]

Set cursor color and type:

(setq default-frame-alist
	    '((cursor-type . 'bar)
	      (cursor-color . "red")))

Then resize the frame so that the window is just about wide enough to displ=
ay one of the lines in the current buffer.

Move point to end of one of the longest line.

Note cursor changes color to black.  Move point one to the left, and cursor=
will change back to what it's supposed to be.

Also (not demonstrated here), the cursor will change size to small if the default face in this buffer is enlarged with an entry in `face-remapping-alist'.


I’ve only noticed this today after merging the latest changes on the -24 branch into my Aquamacs branch, so this looks like a regression to me.

1. I don't see that on MS Windows, with this build, from emacs -Q:

In GNU Emacs 24.4.50.1 (i686-pc-mingw32)
 of 2014-08-15 on LEG570
Repository revision: 117706 rgm@gnu.org-20140815043406-p5hbu97cbm7pulcn
Windowing system distributor `Microsoft Corp.', version 6.1.7601
Configured using:
 `configure --enable-checking 'CFLAGS=-O0 -g3' CPPFLAGS=-DGLYPH_DEBUG=1'

2. You probably also meant (cursor-type . bar), not (cursor-type . 'bar).

(With the quote I get a hollow red box, not a red bar.)

I do not see that either (on Windows).

Hm, the version you report from shows a build of 8/15 (FWIW, my build
is also from 8/15).

HTH.

Not reproducible here, with today's emacs-24 branch.

I cannot reproduce this, either.  You didn't say how you enlarged the
font; I did that with "C-x C-+".

Could be Aquamacs specific.

Just for the record: David uses a build from the release branch in the
repository, not from the trunk.

Do you have overflow-newline-into-fringe set to non-nil?  If so, then this
is a problem specific to the NS port:  the cursor is being displayed in the
foreground color of your fringe
face.  This doesn't look like a regression, though, so fixed in trunk
(r117858).

I haven't looked at the face remapping issue.

I used the pretest as indicated and replicated it.

What I’m doing is

Emacs -Q

(setq default-frame-alist
	    '((cursor-type . bar)
	      (cursor-color . "red")))

C-x 5 2

Move cursor to end of longest line (“red”))) in my case)

Resize frame horizontally so that the cursor shows up in the right fringe (see screenshot).  38x43 in my case.

I can’t do that either, because I can’t get the cursor to show up in the fringe.  That’s why I didn’t give you a recipe.  This one came just from Aquamacs.

> Could be Aquamacs specific.

Could be NS / Mac specific.  The screenshot is taken with GNU Emacs 24.3.93.1.

Yes overflow-newline-into-fringe is t.  This is obviously the default then.

OK, thanks for your fix.  I’m going to grab and merge it.  If I see the problem again, I’ll update this bug.
