Description Bastien Nocera 2006-11-17 06:01:04 EST

When using "-r" gzip will try to restore the atime and mtime of the directory
passed using utime(), thus breaking cache invalidation for NFS (which relies on
the mtime).

The code does this on purpose:
   /* If the input name is that of a directory, recurse or ignore: */
   if (S_ISDIR(istat.st_mode)) {
#if ! NO_DIR
       if (recursive) {
           struct stat st;
           st = istat;
           treat_dir(iname);
           /* Warning: ifname is now garbage */
#  ifndef NO_UTIME
           reset_times (iname, &st);
#  endif
       } else

I tried mailing Jean-Loup and the bug list (as per
http://www.math.utah.edu/docs/info/gzip_8.html#SEC11 followed from gzip.org)
without success (bounced mails).

What's the reasoning behind restoring the mtime for the directory?
