K 10 svn:author V 8 kientzle K 8 svn:date V 27 2004-04-05T21:12:29.000000Z K 7 svn:log V 411 Overhauled ACL support. This makes us compatible with 'star' ACL handling, though there's still a bit more work needed in this area. Added 'write_open_fd' and 'read_open_fd' to simplify, e.g., tar's u and r modes. Eliminated old 'write_open_file_position' as a bad idea. (It required closing/reopening files to do updates, which led to unpleasant implications.) Various other minor fixes, API tweaks, etc. END
