Lewis Marshall	54aeb8e4c0	p2p/simulations: various stability fixes (#15198) ... p2p/simulations: introduce dialBan - Refactor simulations/network connection getters to support avoiding simultaneous dials between two peers If two peers dial simultaneously, the connection will be dropped to help avoid that, we essentially lock the connection object with a timestamp which serves as a ban on dialing for a period of time (dialBanTimeout). - The connection getter InitConn can be wrapped and passed to the nodes via adapters.NodeConfig#Reachable field and then used by the respective services when they initiate connections. This massively stablise the emerging connectivity when running with hundreds of nodes bootstrapping a network. p2p: add Inbound public method to p2p.Peer p2p/simulations: Add server id to logs to support debugging in-memory network simulations when multiple peers are logging. p2p: SetupConn now returns error. The dialer checks the error and only calls resolve if the actual TCP dial fails.	7 years ago
Lewis Marshall	9feec51e2d	p2p: add network simulation framework (#14982) ... This commit introduces a network simulation framework which can be used to run simulated networks of devp2p nodes. The intention is to use this for testing protocols, performing benchmarks and visualising emergent network behaviour.	7 years ago
Felix Lange	d0eba23af3	all: disable log message colors outside of geth ... Also tweak behaviour so colors are only enabled when stderr is a terminal.	8 years ago
Péter Szilágyi	d4fd06c3dc	all: blidly swap out glog to our log15, logs need rework	8 years ago
Firescar96	4c3da0f2e1	node, p2p, internal: Add ability to remove peers via admin interface	8 years ago
Felix Lange	542b839ec7	node, p2p: move network config out of Server ... This silences a go vet message about copying p2p.Server in package node.	9 years ago

Felix Lange	bfbcfbe4a9	all: fix license headers one more time ... I forgot to update one instance of "go-ethereum" in commit 3f047be5a.	9 years ago
Felix Lange	3f047be5aa	all: update license headers to distiguish GPL/LGPL ... All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".	9 years ago

Felix Lange	1440f9a37a	p2p: new dialer, peer management without locks ... The most visible change is event-based dialing, which should be an improvement over the timer-based system that we have at the moment. The dialer gets a chance to compute new tasks whenever peers change or dials complete. This is better than checking peers on a timer because dials happen faster. The dialer can now make more precise decisions about whom to dial based on the peer set and we can test those decisions without actually opening any sockets. Peer management is easier to test because the tests can inject connections at checkpoints (after enc handshake, after protocol handshake). Most of the handshake stuff is now part of the RLPx code. It could be exported or move to its own package because it is no longer entangled with Server logic.	10 years ago

Felix Lange	914e57e49b	p2p: fix disconnect at capacity ... With the introduction of static/trusted nodes, the peer count can go above MaxPeers. Update the capacity check to handle this. While here, decouple the trusted nodes check from the handshake by passing a function instead.	10 years ago

Felix Lange	fc747ef4a6	p2p/discover: new endpoint format ... This commit changes the discovery protocol to use the new "v4" endpoint format, which allows for separate UDP and TCP ports and makes it possible to discover the UDP address after NAT.	10 years ago
Felix Lange	b3c058a9e4	p2p: improve disconnect signaling at handshake time ... As of this commit, p2p will disconnect nodes directly after the encryption handshake if too many peer connections are active. Errors in the protocol handshake packet are now handled more politely by sending a disconnect packet before closing the connection.	10 years ago
Felix Lange	5ba51594c7	p2p: use package rlp to encode messages ... Message encoding functions have been renamed to catch any uses. The switch to the new encoder can cause subtle incompatibilities. If there are any users outside of our tree, they will at least be alerted that there was a change. NewMsg no longer exists. The replacements for EncodeMsg are called Send and SendItems.	10 years ago
Felix Lange	7964f30dcb	p2p: msg.Payload contains list data ... With RLPx frames, the message code is contained in the frame and is no longer part of the encoded data. EncodeMsg, Msg.Decode have been updated to match. Code that decodes RLP directly from Msg.Payload will need to change.	10 years ago
Felix Lange	736e632215	p2p: use RLPx frames for messaging	10 years ago
Felix Lange	73f94f3755	p2p: disable encryption handshake ... The diff is a bit bigger than expected because the protocol handshake logic has moved out of Peer. This is necessary because the protocol handshake will have custom framing in the final protocol.	10 years ago
Felix Lange	2cf4fed11b	cmd/mist, eth, javascript, p2p: use Node URLs for peer suggestions	10 years ago
Felix Lange	e34d134102	p2p: fixes for actual connections ... The unit test hooks were turned on 'in production'.	10 years ago
Felix Lange	8564eb9f7e	p2p/discover: add node URL functions, distinguish TCP/UDP ports ... The discovery RPC protocol does not yet distinguish TCP and UDP ports. But it can't hurt to do so in our internal model.	10 years ago
Felix Lange	5bdc115943	p2p: integrate p2p/discover ... Overview of changes: - ClientIdentity has been removed, use discover.NodeID - Server now requires a private key to be set (instead of public key) - Server performs the encryption handshake before launching Peer - Dial logic takes peers from discover table - Encryption handshake code has been cleaned up a bit - baseProtocol is gone because we don't exchange peers anymore - Some parts of baseProtocol have moved into Peer instead	10 years ago
