[PATCH v3 06/11] bundle-uri client: add helper for testing server

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Add a 'test-tool bundle-uri ls-remote' command. This is a thin wrapper
for issuing protocol v2 "bundle-uri" commands to a server, and to the
parsing routines in bundle-uri.c.

In the "git clone" case we'll have already done the handshake(),
but not here. Add an extra case to check for this handshake in
get_bundle_uri() for ease of use for future callers. Rename the existing
'got_remote_heads' to 'finished_handshake' to make it more clear what
that bit represents.
