24.0.50; regression: special-display-frame is no longer dedicated |
|
Date: |
Mon, 13 Jun 2011 09:08:05 -0700 |
This regression was introduced between this build (from today,
6/13/2011) and the Windows build of LAST week, which was this:
In GNU Emacs 24.0.50.1 (i386-mingw-nt5.1.2600)
of 2011-06-06 on 3249CTO
Windowing system distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (4.5) --no-opt --cflags
-Ic:/build/include'
I don't have a recipe starting from emacs -Q. But these are the
symptoms:
I have non-nil `pop-up-frames'. I use a special-display frame for
buffers such as `*Buffer List*' and `*info*'.
My value of `special-display-regexps' is this:
("[ ]?[*][^*]+[*]")
My special-display frames hav a different background color from my
regular frames. I visit a file foo.el, then use `C-x 5 0' to remove
its frame. I hit C-x C-b and get the buffer menu in a new,
special-display frame. I click mouse-2 on the foo.el line to
visit that file.
Prior to this week's build, this opens foo.el in a new frame, in a
regular frame. With this week's build it visits foo.el in the same
frame that showed `*Buffer List*'. IOW, `pop-up-frames' is not being
respected (in the case where there is not already a frame showing
foo.el).
What is happening is that `Buffer-menu-mouse-select' is incorrectly
invoking `switch-to-buffer' instead of `switch-to-buffer-other-window'.
This is happening because the window of the special-display buffer is
not dedicated, as it should be.
This returns nil:
(window-dedicated-p #<window 14 on *Buffer List*>)
Similarly, M-: (window-dedicated-p (selected-window)) in any
special-display buffer window returns nil. It should return non-nil.
In my setup the windows of buffers such as `*Buffer List*' and `*info*'
should definitely be dedicated. They are special-display buffers (and
their special-display-frame backgrounds confirm this).
As the manual says, and as has always been the behavior in previous
Emacs versions, "By default, special display means to give the buffer a
dedicated frame."
The frames showing special-display buffers should be dedicated frames.
Clicking mouse-2 on a buffer name in `*Buffer List*' should not visit
that buffer in the same window/frame.

Good, thanks,
