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

holisticode	32516c768e	cmd/swarm: add config file (#15548) ... This commit adds a TOML configuration option to swarm. It reuses the TOML configuration structure used in geth with swarm customized items. The commit: * Adds a "dumpconfig" command to the swarm executable which allows printing the (default) configuration to stdout, which then can be redirected to a file in order to customize it. * Adds a "--config <file>" option to the swarm executable which will allow to load a configuration file in TOML format from the specified location in order to initialize the Swarm node The override priorities are like follows: environment variables override command line arguments override config file override default config.	7 years ago

ΞTHΞЯSPHΞЯΞ	4d300e4dec	swarm: plan bee for content storage and distribution on web3 ... This change imports the Swarm protocol codebase. Compared to the 'swarm' branch, a few mostly cosmetic changes had to be made: * The various redundant log message prefixes are gone. * All files now have LGPLv3 license headers. * Minor code changes were needed to please go vet and make the tests pass on Windows. * Further changes were required to adapt to the go-ethereum develop branch and its new Go APIs. Some code has not (yet) been brought over: * swarm/cmd/bzzhash: will reappear as cmd/bzzhash later * swarm/cmd/bzzup.sh: will be reimplemented in cmd/bzzup * swarm/cmd/makegenesis: will reappear somehow * swarm/examples/album: will move to a separate repository * swarm/examples/filemanager: ditto * swarm/examples/files: will not be merged * swarm/test/*: will not be merged * swarm/services/swear: will reappear as contracts/swear when needed	8 years ago
