Thanks for digging into the spec. I agree that it's pretty clear that the appropriate content-type is expected. > Of course we don't know if other implementations follow the spec, but > ISTM that this patch at least doesn't contradict how we've promised the > protocols should work. These seem like pretty unlikely ways for a buggy server to behave, so I think it's a reasonable risk. I also checked GitHub's implementation (which recently learned to speak v2) and made sure that it works. :) I didn't check JGit, but given the provenance, I assume it's fine. Amusingly, this does break the test you just added, because it tries to issue an ERR after claiming "text/html" (and after my patch, we correctly fall back to dumb-http). > If no one has any objections, I'll include the diff below in v2. Thanks > for the help Jeff! I think it makes sense to do the refactoring first as a separate step. And of course it needs a commit message. So how about this series (your original is rebased on top)?
