Felföldi Zsolt	0851646e48	les, les/lespay/client: add service value statistics and API (#20837 ) This PR adds service value measurement statistics to the light client. It also adds a private API that makes these statistics accessible. A follow-up PR will add the new server pool which uses these statistics to select servers with good performance.

Felix Lange	e83c3ccc47	p2p/enode: improve IPv6 support, add ENR text representation (#19663 ) * p2p/enr: add entries for for IPv4/IPv6 separation This adds entry types for "ip6", "udp6", "tcp6" keys. The IP type stays around because removing it would break a lot of code and force everyone to care about the distinction. * p2p/enode: track IPv4 and IPv6 address separately LocalNode predicts the local node's UDP endpoint and updates the record. This change makes it predict IPv4 and IPv6 endpoints separately since they can now be in the record at the same time. * p2p/enode: implement base64 text format * all: switch to enode.Parse(...) This allows passing base64-encoded node records to all the places that previously accepted enode:// URLs. The URL format is still supported. * cmd/bootnode, p2p: log node URL instead of ENR ...and return the base64 record in NodeInfo.	6 years ago
Felix Lange	6f607de5d5	p2p, p2p/discover: add signed ENR generation (#17753 ) This PR adds enode.LocalNode and integrates it into the p2p subsystem. This new object is the keeper of the local node record. For now, a new version of the record is produced every time the client restarts. We'll make it smarter to avoid that in the future. There are a couple of other changes in this commit: discovery now waits for all of its goroutines at shutdown and the p2p server now closes the node database after discovery has shut down. This fixes a leveldb crash in tests. p2p server startup is faster because it doesn't need to wait for the external IP query anymore.	6 years ago
Felix Lange	30cd5c1854	all: new p2p node representation (#17643 ) Package p2p/enode provides a generalized representation of p2p nodes which can contain arbitrary information in key/value pairs. It is also the new home for the node database. The "v4" identity scheme is also moved here from p2p/enr to remove the dependency on Ethereum crypto from that package. Record signature handling is changed significantly. The identity scheme registry is removed and acceptable schemes must be passed to any method that needs identity. This means records must now be validated explicitly after decoding. The enode API is designed to make signature handling easy and safe: most APIs around the codebase work with enode.Node, which is a wrapper around a valid record. Going from enr.Record to enode.Node requires a valid signature. * p2p/discover: port to p2p/enode This ports the discovery code to the new node representation in p2p/enode. The wire protocol is unchanged, this can be considered a refactoring change. The Kademlia table can now deal with nodes using an arbitrary identity scheme. This requires a few incompatible API changes: - Table.Lookup is not available anymore. It used to take a public key as argument because v4 protocol requires one. Its replacement is LookupRandom. - Table.Resolve takes enode.Node instead of NodeID. This is also for v4 protocol compatibility because nodes cannot be looked up by ID alone. - Types Node and NodeID are gone. Further commits in the series will be fixes all over the the codebase to deal with those removals. p2p: port to p2p/enode and discovery changes This adapts package p2p to the changes in p2p/discover. All uses of discover.Node and discover.NodeID are replaced by their equivalents from p2p/enode. New API is added to retrieve the enode.Node instance of a peer. The behavior of Server.Self with discovery disabled is improved. It now tries much harder to report a working IP address, falling back to 127.0.0.1 if no suitable address can be determined through other means. These changes were needed for tests of other packages later in the series. * p2p/simulations, p2p/testing: port to p2p/enode No surprises here, mostly replacements of discover.Node, discover.NodeID with their new equivalents. The 'interesting' API changes are: - testing.ProtocolSession tracks complete nodes, not just their IDs. - adapters.NodeConfig has a new method to create a complete node. These changes were needed to make swarm tests work. Note that the NodeID change makes the code incompatible with old simulation snapshots. * whisper/whisperv5, whisper/whisperv6: port to p2p/enode This port was easy because whisper uses []byte for node IDs and URL strings in the API. * eth: port to p2p/enode Again, easy to port because eth uses strings for node IDs and doesn't care about node information in any way. * les: port to p2p/enode Apart from replacing discover.NodeID with enode.ID, most changes are in the server pool code. It now deals with complete nodes instead of (Pubkey, IP, Port) triples. The database format is unchanged for now, but we should probably change it to use the node database later. * node: port to p2p/enode This change simply replaces discover.Node and discover.NodeID with their new equivalents. * swarm/network: port to p2p/enode Swarm has its own node address representation, BzzAddr, containing both an overlay address (the hash of a secp256k1 public key) and an underlay address (enode:// URL). There are no changes to the BzzAddr format in this commit, but certain operations such as creating a BzzAddr from a node ID are now impossible because node IDs aren't public keys anymore. Most swarm-related changes in the series remove uses of NewAddrFromNodeID, replacing it with NewAddr which takes a complete node as argument. ToOverlayAddr is removed because we can just use the node ID directly.	6 years ago
