I noticed on OS X that editing an executable shell script in visual diff would reset the file to 644 after saving. The problem only occurred if a snapshot was required, e.g. if there was more than one file in the diff. It looks like util.copyfile() preserves the mode when copying from $tmp back to wdir(), so it was just a matter of copying the mode when first creating the temp file. This code was ripped off from the extdiff extension prior to it switching to using archive, but I left out the symlink case since this code isn't using wopener. Perhaps this should be switched to use archive as well, which would allow subrepo support. --HG-- branch : stable
