To disable TLS 1.3, simply remove VersionTLS13 from supportedVersions, as tested by TestEscapeRoute, and amend documentation. To make it opt-in, revert the change to (*Config).supportedVersions from this CL. I did not have the heart to implement the early data skipping feature when I realized that it did not offer a choice between two abstraction-breaking options, but demanded them both (look for handshake type in case of HelloRetryRequest, trial decryption otherwise). It's a lot of complexity for an apparently small gain, but if anyone has strong opinions about it let me know. Note that in TLS 1.3 alerts are encrypted, so the close_notify peeking to return (n > 0, io.EOF) from Read doesn't work. If we are lucky, those servers that unexpectedly close connections after serving a single request will have stopped (maybe thanks to H/2) before they got updated to TLS 1.3. Relatedly, session tickets are now provisioned on the client first Read instead of at Handshake time, because they are, well, post-handshake messages. If this proves to be a problem we might try to peek at them. Doubled the tests that cover logic that's different in TLS 1.3. The benchmarks for TLS 1.2 compared to be0f3c286b5 (before TLS 1.3 and its refactors, after CL 142817 changed them to use real connections) show little movement. name old time/op new time/op delta
