File move (rename) bug

[iychoi]

Hi.

I met a bug while file move (rename) on syndicatefs.

I used local MS for testing and the bug is replayable as following below sequence.

• Create a directory in Syndicate
• Try to rename the directory with "mv" command.

Here's my commands

iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ touch abc.txt ls iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ ls abc.txt iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ mv abc.txt ren.txt iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ ls ren.txt iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ mkdir fake iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ ls fake ren.txt iychoi@iychoi-virtual-machine:/mnt/syndicatefs$ mv fake face mv: cannot move fake' to a subdirectory of itself,face' iychoi@iychoi-virtual-machine:/mnt/syndicatefs$

Thanks for your time.

Directory rename is currently not supported. There's no easy way to do this, since we name files by their paths (which means changing a directory name will entail atomically renaming a scalable number of MSEntry records). Issue #18, when it is addressed, will pave the way to directory renaming, since once we name files and directories by a globally-unique identifier independent of path (e.g. an "i-node" number), changing the directory name will have no bearing on the files and directories beneath it.

Thank you for your comment. I haven't thought in that way. Anyway, this isn't a big issue for me. I'll temporarily disable the directory rename function until this is fixed.
