Felix Lange	94a8b296e4	p2p/discover: refactor node and endpoint representation (#29844) ... Here we clean up internal uses of type discover.node, converting most code to use enode.Node instead. The discover.node type used to be the canonical representation of network hosts before ENR was introduced. Most code worked with *node to avoid conversions when interacting with Table methods. Since *node also contains internal state of Table and is a mutable type, using *node outside of Table code is prone to data races. It's also cleaner not having to wrap/unwrap *enode.Node all the time. discover.node has been renamed to tableNode to clarify its purpose. While here, we also change most uses of net.UDPAddr into netip.AddrPort. While this is technically a separate refactoring from the *node -> *enode.Node change, it is more convenient because *enode.Node handles IP addresses as netip.Addr. The switch to package netip in discovery would've happened very soon anyway. The change to netip.AddrPort stops at certain interface points. For example, since package p2p/netutil has not been converted to use netip.Addr yet, we still have to convert to net.IP/net.UDPAddr in a few places.	6 months ago
Felix Lange	47cdea5ac5	p2p/discover: concurrent TALKREQ handling (#27112) ... This changes TALKREQ message processing to run the handler on separate goroutine, instead of running on the main discv5 dispatcher goroutine. It's better this way because it allows the handler to perform blocking actions. I'm also adding a new method TalkRequestToID here. The method allows implementing a request flow where one node A sends TALKREQ to another node B, and node B later sends a TALKREQ back. With TalkRequestToID, node B does not need the ENR of A to send its request.	2 years ago
