Peter Enns' implementations of the class projects for CMSC818e.

Same as project 2 except there is no need to wait before killing the program.

If the behavior is slightly different from what was expected, try the -mtimeArchives command line option. By default, archives are created with a timestamp when the versions were committed to the database instead of "modified time" (this allows for directories to have multiple versions when a file inside them is written to, which is not true of Mtime).

1. Directory archive code is mostly in myfs/directory.go, and some small modifications in myfs/node.go and myfs/fs.go.

1. Save this folder in $GOPATH/src. It must be called dss.
2. "go get" bazil fuse and goleveldb
3. Run "go run memfs.go /mount/point /path/do/db" (db directory doesn't need to exist)
4. Make sure to wait at least 5 seconds after any action before you kill it so it has a chance to write to the db.

If you run into trouble running it, email me at slunk@umd.edu

• Persistence is mostly taken care of in myfs/db.go, myfs/fs.go, myfs/dir.go, and myfs/file.go
• Rabin-Karp chunking is taken care of in util/rk.go
• Concurrent flusher code is mostly in fs.go, goroutine run in memfs.go

You can run "go test dss/test" to run a small suite of unit tests. Should pass as long as it has write access to /tmp.
