Subject: bug#11067: 24.0.94.1; diff-buffer-with-file
Date: Thu, 22 Mar 2012 14:54:16 +0000 (UTC) [thread overview]
Message-ID: <alpine.LFD.2.02.1203221430400.49632@hafstokkur.hafro.is> (raw)
I'm running Emacs 24.0.94.1 alpha,
http://alpha.gnu.org/gnu/emacs/windows/emacs-20120319-r107630-bin-i386.zip
and `diff-buffer-with-file' is not working like it did in Emacs 23.4.1
1. Start emacs -Q
2. Set `diff-command' to "winmerge" and `diff-switches' to nil
3. Open a file, say c:/gnu/emacs/BUGS, make some changes without saving
4. M-x diff-buffer-with-file
Emacs 23.4.1 performs this task very nicely, but Emacs 24.0.94.1 alpha
provides the external program with args that cannot be compared:
c:\gnu\emacs\-L
c:\gnu\emacs\BUGS
Examining the Emacs *Diff* buffer provides some insights. In Emacs 23.4.1
it contains
winmerge "c:/gnu/emacs/BUGS" "c:/Temp/buffer-content-3436L7C"
which looks sensible, but in Emacs 24.0.94.1 alpha it the *Diff* buffer
contains
winmerge "-L" "c:/gnu/emacs/BUGS" "-L" "#<buffer BUGS>"
"c:/gnu/emacs/BUGS" "c:/Temp/buffer-content-2640boz"
which looks like 6 args instead of 2, including some "-L" options (even
after specifically disabling all diff switches) and "#<buffer BUGS>"
(probably of no use to an external program).
To me, it looks like version 24.0.94.1 of `diff-buffer-with-file' in
diff.el should try harder to mimic the behavior of version 23.4.1 in
files.el.
Many thanks,
Arni
