Hi again Experienced another real minor problem. Not sure if this occures in your current SVN version too. If you create a directory node it is not inserted into the 'last_modified' index. Ok, no problem so far. But if you now call write_stat on this directory (touch -c -a -m <directory>) the write_stat function calls: index.UpdateLastModified(transaction, inode, (bigtime_t)stat->st_mtime << INODE_TIME_SHIFT); which will try to remove and reinsert it into the index. The remove operation (BPlusTree::Remove) will return with an error at // first round, check for duplicate entries status_t status = FindKey(node, key, keyLength, &nodeAndKey.keyIndex); if (status < B_OK) RETURN_ERROR(status); and prints a warning/error. (Could not find value in index "last_modified"!) Wouldn't it be better to not update/insert the key for the last_modified index for directories? (else using write_stat one will add directory nodes to the last_modified index). Thanks, Robert
