The short answer is yes, it could be done that way. Both methods--extending
upload-pack and creating a new service--were suggested in different
However, my thought was to implement the separate service because:
- It is much easier for an admin trying the feature to sanity check the
output of an executable, compared to passing messages to upload-pack.
- In the other scenario, upload-pack might get too expansive in size
and scope--not only codewise, but in terms of config namespace if
"uploadpack" concerns too many things that are only tangentially
related (the properties of the primer resource).
- The transport_prime_clone API can be called independent of other
transport API functions, which might prove useful when revisiting or
- You favored the creation of a service in our original discussion .
I'm not sure if your reasoning was similar to mine.
It definitely was a tight decision--for me, ultimately weighing the value added
in usability (point 1) against the need for a "failsafe" implementation. All
the other points are more speculative, IMO, but the first was strong enough for
What do you think?

These are fair points. Changing for the revised version.
