use a sync.Pool for ackhandler.Frames (#3656) 2023-01-17 23:15:02 -08:00
Marten Seemann
d9665c632e use a sync.Pool to reduce allocation of linked list elements 
Especially the sentPacketHistory linked list shows up in allocation
profiles, since a new list element is allocated for every single packet
we send.
Using a pool for the receiving path, as well as for the frame sorter, is
less critical, since we're tracking ranges there instead of individual
packets / frames, but it doesn't hurt either.
The other occurrences where we use a linked list (connection ID tracking
and the token store) are used so rarely (a few times over the lifetime
of the connection) that using a pool doesn't make any sense there.

ackhandler: reject duplicate packets in ReceivedPacket (#3568) 
Before we process a packet, IsPotentiallyDuplicate is called.
This should filter out all duplicates before the reach ReceivedPacket.

17d9860db6 declare the handshake confirmed when receiving an ACK for a 1-RTT packet 
... on the client side. Both the receipt of HANDSHAKE_DONE and the
receipt of an ACK for a 1-RTT packet are sufficient for declaring
confirmation of the handshake.
