Actually, I think this line may be buggy. Hold off submitting if you
haven't already.
Including the HEAD ref in the advertisement from /info/refs ends up
duplicating it, since the dumb client unconditionally fetches the file
/HEAD to use as the that ref. I think the right thing to do is
generate the correct /HEAD using head_ref_namespaced(), rather than
returning the bare file $GIT_DIR/HEAD, but I'm not 100% sure how HEAD
and namespaces interact, since I haven't been able to produce a repo
with a different HEAD in a namespace. Can you verify this approach?
$ GIT_SMART_HTTP=0 ./git ls-remote http://localhost:8080/ | grep HEAD
bd9cd9a1859aa464b3092f2023b3a4040166572d HEAD
bd9cd9a1859aa464b3092f2023b3a4040166572d HEAD
Generates these requests (ignore the errors):
2013/04/04 18:18:49 /info/refs
2013/04/04 18:18:49 http: invalid Content-Length of "3285\r\n" sent
2013/04/04 18:18:49 /HEAD
2013/04/04 18:18:49 http: invalid Content-Length of "41\r\n" sent
I didn't catch this before, since the smart protocol includes HEAD in
its response, and I was trying to make the two match.
