Author: kientzle Date: Tue Oct 21 05:08:35 2008 New Revision: 184109 URL: http://svn.freebsd.org/changeset/base/184109 Log: If we don't know the file size, leave the file size unset. If it's not a regular file, don't return any data, even if the size is unknown. Update the Zip test with a hand-tweaked Zip archive that has a directory (with length-at-end set), a regular file without length-at-end set, and a regular file with length-at-end set and a bad CRC. Update the test code to verify that the file size is unset for the regular file with length-at-end.
