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	ea54283b30	all: update license information	10 years ago
Péter Szilágyi	d84638bd31	p2p: support protocol version negotiation	10 years ago
Felix Lange	70da79f04c	p2p: improve disconnect logging	10 years ago
Felix Lange	8dcbdcad0a	p2p: track write errors and prevent writes during shutdown As of this commit, we no longer rely on the protocol handler to report write errors in a timely fashion. When a write fails, shutdown is initiated immediately and no new writes can start. This will also prevent new writes from starting after Server.Stop has been called.	10 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	64564da20b	p2p: decrease maximum message size for devp2p to 1kB The previous limit was 10MB which is unacceptable for all kinds of reasons, the most important one being that we don't want to allow the remote side to make us allocate 10MB at handshake time.	10 years ago
Felix Lange	dbdc5fd4b3	p2p: delete Server.Broadcast	10 years ago
Felix Lange	691cb90284	p2p: log remote reason when disconnect is requested The returned reason is currently not used except for the log message. This change makes the log messages a bit more useful. The handshake code also returns the remote reason.	10 years ago
Felix Lange	d4f0a67323	p2p: drop connections with no matching protocols	10 years ago
Felix Lange	6a2fec5309	p2p, whisper: use glog for peer-level logging	10 years ago
Felix Lange	b34a8ef624	p2p, p2p/discover: protocol version 4	10 years ago
obscuren	01e3d694a6	p2p: added received at to peer message p2p.Msg.ReceivedAt can be used for determining block propagation from begining to end.	10 years ago
Felix Lange	995fab2ebc	p2p: fix yet another disconnect hang Peer.readLoop will only terminate if the connection is closed. Fix the hang by closing the connection before waiting for readLoop to terminate. This also removes the british disconnect procedure where we're waiting for the remote end to close the connection. I have confirmed with @subtly that cpp-ethereum doesn't adhere to it either.	10 years ago
Felix Lange	99a1db2d40	p2p: don't mess with the socket deadline in Peer.readLoop netWrapper already sets a read deadline in ReadMsg.	10 years ago
Felix Lange	f1d710af00	p2p: fix Peer shutdown deadlocks There were multiple synchronization issues in the disconnect handling, all caused by the odd special-casing of Peer.readLoop errors. Remove the special handling of read errors and make readLoop part of the Peer WaitGroup. Thanks to @Gustav-Simonsson for pointing at arrows in a diagram and playing rubber-duck.	10 years ago
Felix Lange	a7bced779a	p2p: log disconnect requests This helps a lot with debugging.	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	22659a7fea	p2p: restore read/write timeouts They got lost in the transition to rlpxFrameRW.	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	3dbd32093c	p2p: enable devp2p ping This should prevent connection drops.	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	32a9c0ca80	p2p: bump devp2p protcol version to 3 For compatibility with cpp-ethereum	10 years ago
Felix Lange	fd3e1061e0	p2p: handle disconnect before protocol handshake	10 years ago
Felix Lange	5110f80bba	p2p: improve read deadlines There are now two deadlines, frameReadTimeout and payloadReadTimeout. The frame timeout is longer and allows for connections that are idle. The message timeout is still short and ensures that we don't get stuck in the middle of a message.	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	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

zelig	54252ede31	add temporary forced session token generation	10 years ago
zelig	faa069a126	peer-level integration test for crypto handshake - add const length params for handshake messages - add length check to fail early - add debug logs to help interop testing (!ABSOLUTELY SHOULD BE DELETED LATER) - wrap connection read/writes in error check - add cryptoReady channel in peer to signal when secure session setup is finished - wait for cryptoReady or timeout in TestPeersHandshake	10 years ago
zelig	58fc2c679b	important fix for peer pubkey. when taken from identity, chop first format byte!	10 years ago
zelig	e252c634cb	first stab at integrating crypto in our p2p - abstract the entire handshake logic in cryptoId.Run() taking session-relevant parameters - changes in peer to accomodate how the encryption layer would be switched on - modify arguments of handshake components - fixed test getting the wrong pubkey but it till crashes on DH in newSession()	10 years ago
