When remote.name.annexUrl is an annex+http(s) url, that uses the same
hostname as remote.name.url, which is itself a http(s) url, they are
assumed to share a username and password.
This avoids unnecessary duplicate password prompts.
Changed the protocol docs because servant parses "true" and "false" for
booleans in query parameters, not "1" and "0".
clientPut with datapresent=True is not used by git-annex, and I don't
anticipate it being used in git-annex, except for testing.
I've tested this by making clientPut be called with datapresent=True and
git-annex copy to a remote succeeds once the object file is first
manually copied to the remote. That would be a good test for the test
suite, but running the http client means exposing it to at least
localhost, and would fail if a real http client was already running on
that port.
When getting from a P2P HTTP remote, prompt for credentials when required,
instead of failing.
This feels like it might be a bug in servant-client. withClientM's type
suggests it would not throw a ClientError. But it does in this case.
The user doesn't want to see a uuid in the prompt.
Also, when a http server is proxying, multiple remotes will have the
same base url, and the same password will work for them all.
