The following patches extend what I sent out as an WIP
(https://public-inbox.org/git/[email protected]/) and
implement protocol version 2.
Some changes from that series are as follows:
* Lots of various cleanup on the ls-refs and fetch command code, both server
and client.
* Fetch command now supports a stateless-rpc mode which enables communicating
with a half-duplex connection.
* Introduce a new remote-helper command 'connect-half-duplex' which is
implemented by remote-curl (the http remote-helper). This allows for a
client to establish a half-duplex connection and use remote-curl as a proxy
to wrap requests in http before sending them to the remote end and
unwrapping the responses and sending them back to the client's stdin.
* The transport code is refactored for ls-remote, fetch, and push to provide a
list of ref-patterns (based on the refspec being used) when requesting refs
from the remote end. This allows the ls-refs code to send this list of
patterns so the remote end and filter the refs it sends back.
This series effectively implements protocol version 2 for listing a remotes
refs (ls-remote) as well as for fetch for the builtin transports (ssh, git,
file) and for the http/https transports. Push is not implemented yet and
doesn't need to be implemented at the same time as fetch since the
receive-pack code can default to using protocol v0 when v2 is requested by the
client.
Any feedback is appreciated! Thanks!
