When grep is passed -r, recursive_action will treat any symlinks to directories not in the root as normal files, since it lstat's them and is therefore told they are not directories. However, file_action_grep will still try to fopen and read from them to see whether they match, which varies in behaviour across platforms. Linux will give EISDIR and thus grep will not find any matching lines, but FreeBSD will give the raw contents of the directory itself, which may match the given pattern. Also, if grep is passed -c, it will even print a count for these symlinks, even on Linux. Since this recursive_action behaviour is required for the correct functioning of other applets, such as tar, grep should handle this special case and skip any such symlinks. function old new delta file_action_grep 80 161 +81 Signed-off-by: James Clarke <jrtc27@jrtc27.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com> |
