bug#6786: 23.2; Ido-mode switch-to-buffer switches frames

[Joel James Adamson]

[-- Attachment #1: Type: text/plain, Size: 10256 bytes --]

emacs -Q; open a new frame using "C-x 5 2" and switch to that frame.
Then switch from *scratch* to *Messages* in the first frame.  Enable
ido-mode using "M-x ido-mode".  Switch to the second frame and try
switching to *Messages*.  The point (and focus) move to the other
window.

Setting the ido-mode variables `ido-default-file-method' and
`ido-default-buffer-method' to 'selected-window does not change this
behavior.

This is infuriating!  I should be able to switch to whatever buffer I
want with multiple frames and not have the focus change.  Let me give
you an example: I have a gdb session running, so I have several frames,
one for output, one for backtrace and one for the gdb controller.  For
some reason the gdb frame was split into two windows and I accidentally
deleted the wrong one and now the Separate IO is going into the gdb
buffer.  However, when I try to to switch back to the *gud* buffer, it
puts the point in a completely different window.  I don't want *gud* in
that frame, I want it in the one I'm trying to put it in!  NOTE: THIS
BEHAVIOR PERSISTS EVEN AFTER SWITCHING OUT OF IDO-SWITCH-BUFFER BY
PRESSING "C-b".

The buffer-switching behavior I submitted earlier also happens when
using the Buffers menu.

I have no 23.2 to test right now, but the latest trunk does work as
expected, if you set ido-default-buffer-method to 'selected-window.

It does for me with version 24.0.50.1 following your recipe starting
with emacs -Q. The buffer appears on the selected window of the current
frame.

See the variable display-buffer-reuse-frames, it should be `nil' to work
as you want. But that's already the default value son I don't understand
why you see that behavior with emacs -Q.

What happens when you set `ido-default-buffer-method' to 'other-window?

Where IO goes to is not related to the window/buffer relationship.

What do you mean by this?  That the *gud* buffer is displayed in the
wrong window?

What is C-b bound to in this situation?

Could you please try to run `display-buffer' with edebug to trace the
behavior you observe?

Usually this can happen only if (1) `pop-up-frames' is non-nil, (2)
`display-buffer-reuse-frames' is non-nil, or (3) the windows on the
selected frame are dedicated.

Then I get window-splitting.  Should that affect frame-based behavior?

I don't think it's related to the bug, it was just part of my narrative
describing the problem.

>> However, when I try to to switch back to the *gud* buffer, it
>> puts the point in a completely different window.

In the wrong frame: for example, say *gud* originally was in frame 1;
then I accidentally switch buffers (so no frame displays the *gud*
buffer).  Then with the point in frame 1 I switch buffers and *gud* pops
up in frame 2.

C-b in ido-switch-buffer reverts to normal (non-ido) buffer-switching.
So if you start a buffer-switch with C-xb, the ido menu comes up; if you
press C-b you get the regular buffer switch prompt.

*gud* should be dedicated when I open the frame from the GDB menu;
unfortunately it doesn't "stay dedicated," it rather switches its
dedication to another frame Benedict Arnold-style.

Since nobody could repeat this behavior with the current trunk I'm
closing this bug.  If the erroneous behavior persists on your machine,
please give the precise sequence of the actions you applied here.

Thanks, martin
