When using GIT_NAMESPACE, it appears the "symref" added to the capabilities advertisement doesn't get the namespace stripped. The namespace is stripped for the advertised refs, including "HEAD", but not on the "symref".

Either way, since the clone can't find the HEAD value (either because it doesn't see "refs/namespaces/foo/HEAD" as HEAD, which I'd assume is the case, or because it can't find "refs/namespaces/foo/refs/heads/master"), it falls back on the old behavior of picking the first branch with a matching commit. That brings back all the "wrong branch" issues with cloning that adding "symref" fixed. Is this a bug? An oversight? An intentional decision? How is HEAD supposed to work when using GIT_NAMESPACE? Perhaps the expectation is that namespaces won't have their own HEADs? I'd say perhaps it's that even in the namespace the target ref shouldn't be namespaced, but that doesn't seem like it could possibly be correct since the namespace could contain refs that don't exist outside it, so Git would see the symbolic ref as broken. Any insight would be greatly appreciated! Bryan
