The protocol design allows the server to respond with some other object;
if a server for some reason a server did that, it would not be right for
git-annex to download its content. I don't think it would be a security
hole, since git-annex is downloading a specific key and will verify the
key's content. Seems like a good idea to belt-and-suspenders test for
such a misuse of the protocol.
I'm seeing the github lfs server request an upload of an object that has
already been uploaded to it before. Probably because they offload
storage to S3 and so skipped the overhead of checking for an unncessary
upload.
Let's keep this entirely pure.
git-annex has its own facilities for running a ssh command, that make it
respect various config settings, and cache connections, etc. So better
not to have the library run ssh itself.
This is a special remote and a git remote at the same time; git can pull
and push to it and git-annex can use it as a special remote.
Remote.Git has to check if it's configured as a git-lfs special remote
and sets it up as one if so.
Object methods not implemented yet.
Use the same optimisation for --in=here as has always been used for --in=.
rather than the slow code path that unncessarily queries the git-annex
branch.
It looks like when "here" got added as an alias for "." back in 2012, I
forgot about this place.
Also sped up some very unlikely ways of referring to the current
repository.
Note that, this could in some rare corner case cause a behavior
change, if the git-annex branch and inAnnex disagree about whether content
is present in the local repository. But --in=. already behaved
that way, and the truth on the ground should win also.
