Cache Invalidation #36

Open bbengfort opened 7 years ago

bbengfort commented 7 years ago

Make sure that FUSE invalidates the kernel cache so that all system calls go through our application.

Check the clockfs example in FUSE.

Added the following methods to Node: invalidate(), InvalidateData(), and InvalidateAttr() based off the methods in [fuse/fs/serve.go#L1431](https://github.com/bazil/fuse/blob/master/fs/serve.go#L1431.

Am calling InvalidateData() in Store() for both Dir and File nodes. However this is not working and am getting a "error flushing filesystem at /~bbengfort: could not invalidate node 1: invalid argument"

I suspect this is about the NodeID attribute ... which I don't know how to deal with quite yet.
