From: Eli Zaretskii <eliz <at> gnu.org> To: 11912 <at> debbugs.gnu.org Subject: bug#11912: 24.1; 'M' in Dired on a symlink does not refresh the display Date: Wed, 11 Jul 2012 19:30:39 +0300
On a system that supports symlinks, do this: emacs -Q C-x d RET Go to any file and type S foobar RET This creates a symlink named 'foobar' to the file on whose line you were when you typed S. Now go to the line of 'foobar' and type this: M 0444 RET Emacs says "Redisplaying...done", but the mode bits of the target of the symlink do not reflect the change. Type 'g', and they will. From a cursory look at the code (dired-do-redisplay), it sounds like Dired assumes that the file to be refreshed is necessarily on the current line (or marked). This is false for symlinks and the 'M' command (and probably a few others, like 'O'), because the file that changes is the target of the symlink. I think this bug was in Emacs since about forever; I tried as far back as Emacs 22.1, and the problem was still there.
