Subject: bug#2295: Viewing images with image-mode changes directory time
Date: Thu, 12 Feb 2009 00:55:48 +0200 [thread overview]
Message-ID: <873aepkksk.fsf@jurta.org> (raw)
Using image-mode to visit image files touches directory modification
dates. This is especially annoying when image files are in an old
archive. The problem is in the function `add-text-properties' that
temporarily modifies the image buffer causing lock-file to create a lock
file in the current directory that modifies the directory timestamp.
As a solution I propose to let-bind `buffer-file-truename' to nil
around the call to `add-text-properties' to prevent directory time
modification:
