ianswett commented on this pull request. Thanks for writing this! I think I'd prefer mentioning HANDSHAKE_DONE explicitly since receiving a 1-RTT ACK also confirms the handshake and I think in this case, it's probably easier to not rely on handshake confirmed? Also be aware of #3461 to update the PTO pseudocode. > @@ -517,7 +517,7 @@ client, it is the client's responsibility to send packets to unblock the server until it is certain that the server has finished its address validation (see Section 8 of {{QUIC-TRANSPORT}}). That is, the client MUST set the probe timer if the client has not received an acknowledgement for one of its -Handshake or 1-RTT packets. +Handshake or 1-RTT packets and the handshake has not been confirmed. As history, this text was written without HANDSHAKE_DONE in mind(because it hadn't been added) and I thought receiving a 1-RTT ACK was going to be how the handshake was confirmed. Technically, receiving an ACK of 1-RTT confirms the handshake, so I prefer "or a HANDSHAKE_DONE frame." instead of "and the handshake has not been confirmed." It's a bit more explicit, now that our mechanisms have stabilized. -- You are receiving this because you are subscribed to this thread.
