Author: wmb Date: 2007-11-14 10:53:14 +0100 (Wed, 14 Nov 2007) New Revision: 730 Modified: ofw/fs/jffs2/jffs2.fth Log: OLPC trac 4898 - fixed handling of deleted files. The problem occured when a deletion entry occurred at a lower NAND block number than a non-deletion entry, with a lower version number, for the same file . The scanning code was too aggressive in discarding RAM record for deleted files, so the file reappeared when the lower-version-number entry was later scanned. The fix is to keep such entries, so the highest version number record is kept regardless of the order in which the nodes are encountered. Deletions are then noticed at a later time, when you search for a file or enumerate a directory. I also added the $readlink method so that "dir" will display the referent of symlinks.
