bug#1073: 23.0.60; Bad interaction between compilation-scroll-output and dedicated windows |

Gnus/5.13 (Gnus v5.13) Emacs/23.0.60 (gnu/linux) |
In GNU Emacs 23.0.60.3 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
of 2008-09-24 on lamacq.ph.ed.ac.uk
Windowing system distributor `The X.Org Foundation', version 11.0.60802000
configured using `configure '-C'
'--prefix=/scratch/s0198183/applications/emacs-trunk/' 'CFLAGS=-ggdb3 -O0'
'--without-rsvg''
If an Emacs frame is split into multiple windows (two will do) of
which one is dedicated and compilation-scroll-output is t then
`compile' in the non-dedicated window will end up moving point.
Steps to reproduce:
emacs -Q --eval \
'(progn
(split-window-vertically)
(set-window-dedicated-p (selected-window) t)
(switch-to-buffer-other-window "*test*")
(insert initial-scratch-message)
(goto-char (point-min))
(setq compilation-scroll-output t)
(compile "echo \"test\"")
(kill-buffer "*compilation*"))'
Note how point is left at the /end/ of the buffer *test* rather
than the beginning. This appears to be a problem with a mismatch
between what `selected-window' and `current-buffer' return.
When this code in `compilation-start' is executed:
(if (buffer-local-value 'compilation-scroll-output outbuf)
(save-selected-window
(select-window outwin)
(goto-char (point-max))))
outwin is #<window 13 on *compilation*>
and after the select-window call (selected-window) is #<window 13
on *compilation*>. However, at this point (current-buffer)
returns *test*, rather than *compilation*.
Cheers,
Lawrence
