Rename does not work about cluefs HOT 4 CLOSED

Thanks for this report. I managed to reproduce it in Ubuntu, but not on MacOS X. From what I have observed, the file is correctly renamed in the shadow directory but its metadata attributes are incorrectly exposed by clueFS after the rename operation.

I think I have a reasonably good idea of where the problem is and am working on fixing it.

As I understand it, the kernel gets node ids from Lookup(). bazil.org/fuse saves those node ids for later access. The kernel knows that the node id does not change when it renames a file. So the next stat() goes to the same old bazil.org/fuse node.

The problem is that the rename operates on the parent directory and not on the file node. So you'd have to somehow find the affected file node and change file.name there.

This problem is solved in go-fuse in the pathfs layer, see https://github.com/hanwen/go-fuse/blob/master/fuse/pathfs/pathfs.go

That it works on OSX is probably because the FUSE module in the OSX kernel is more basic and does not remember the node id when you rename the file.

Edit: go-fuse has a fully working loopback example: https://github.com/hanwen/go-fuse/tree/master/example/loopback

Fixed in master. No release yet since I want to add other modifications before tagging a new release.

Thanks for having reported this problem.
