Comment 3 Pranith Kumar K 2010-08-14 02:59:15 UTC

the present commits should stop the trigger of entry self-heal. We need to enhance the rmdir functionality to complete the fix, which will be fixed as part of 1360

Comment 4 Pranith Kumar K 2010-08-14 03:03:08 UTC

the bug is triggered because checksum of entries in the root directory should not consider .landfill directory. tested it with the same case suggested in the description of the bug.
