Uses go/ssh and pkg/sftp as building blocks and implements the common
sharded.Storage interface, shared between the filesystem and webdav
providers.
A couple of notes:
- The provider assumes the user has a working public/private key
connection to the ssh server.
No other authentication method is supported
- The repository path must exist on the server
- (testing related) The pkg/sftp server doesn't offer a way to set a
server filesystem root, so, during testing, it runs from the local
directory which is repo/blob/sftp. So the tests leave some debris
behind. Additionally, that's the reason why id_rsa and known_hosts
are there at all.
- Encrypted keyfiles are currently not supported (but it could be done)
The splitter in question was depending on
github.com/silvasur/buzhash which is not licensed according to FOSSA bot
Switched to new faster implementation of buzhash, which is
unfortunately incompatible and will split the objects in different
places.
This change is be semi-breaking - old repositories can be read, but
when uploading large objects they will be re-uploaded where previously
they would be de-duped.
Also added 'benchmark splitters' subcommand and moved 'block cryptobenchmark'
subcommand to 'benchmark crypto'.
