Currently most tests pass for me over http2 when running with some minor
tweaks. I still get some aborted connections that aren't retried as cleanly as
with http 1.1. Not sure what causes these yet; but this could also be an httpd
issues.
The only ra function that really causes problems is the implementation of the
replay range api. This 100% expects that results will be received in the same
order in which they are sent. This is typically the correct way in http 1.1
using serf, but even there it is sometimes possible to get results out of
order. (Authentication can re-queue requests... and sometimes authorization is
necessary even when earlier requests succeeded, depending on the auth scheme).
If you want to try this for yourself, you need http 2.4.17 with mod_http2 (or
newer) and OpenSSL 1.0.2 or newer. (If you patch Subversion a bit further you
should be able to use h2c, which avoids the openssl dependency).
