Felix Lange	ea54283b30	all: update license information	9 years ago
Péter Szilágyi	6994a3daaa	p2p: instrument P2P networking layer	10 years ago
Felix Lange	6fb810adaa	p2p: throttle all discovery lookups ... Lookup calls would spin out of control when network connectivity was lost. The throttling that was in place only took effect when the table returned zero results, which doesn't happen very often. The new throttling should not have a negative impact when the host is online. Lookups against the network take some time and dials for all results must complete or hit the cache before a new one is started. This usually takes longer than four seconds, leaving online lookups unaffected. Fixes #1296	10 years ago
Felix Lange	3239aca69b	p2p: bump global write timeout to 20s ... The previous value of 5 seconds causes timeouts for legitimate messages if large messages are sent.	10 years ago
Péter Szilágyi	68898a4d6b	p2p: fix Self() panic if listening is disabled	10 years ago
Péter Szilágyi	e1a0ee8fc5	cmd/geth, cmd/utils, eth, p2p: pass and honor a no discovery flag	10 years ago
Péter Szilágyi	278183c7e7	eth, p2p: start the p2p server even if maxpeers == 0	10 years ago
Felix Lange	9e1fd70b50	p2p: decrease frameReadTimeout to 30s ... This detects hanging connections sooner. We send a ping every 15s and other implementation have similar limits.	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	dbdc5fd4b3	p2p: delete Server.Broadcast	10 years ago
Felix Lange	7efeb4bd96	p2p: bump maxAcceptConns and defaultDialTimout ... On the test network, we've seen that it becomes harder to connect if the queues are so short.	10 years ago
Felix Lange	d4f0a67323	p2p: drop connections with no matching protocols	10 years ago
Felix Lange	9c0f36c46d	p2p: use maxDialingConns instead of maxAcceptConns as dial limit	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
Péter Szilágyi	4d5a719f25	cmd, eth, p2p: introduce pending peer cli arg, add tests	10 years ago
Péter Szilágyi	af93217775	p2p: reduce the concurrent handshakes to 10/10 in/out	10 years ago

Péter Szilágyi	701591b403	cmd, eth, p2p: fix review issues enumerated by Felix	10 years ago
Péter Szilágyi	1528dbc171	p2p: add trust check to handshake, test privileged connectivity ... Conflicts: p2p/server_test.go	10 years ago

Péter Szilágyi	de0549fabb	cmd/geth, cmd/mist, cmd/utils, eth, p2p: support trusted peers	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
Péter Szilágyi	8646365b42	cmd/bootnode, eth, p2p, p2p/discover: use a fancier db design	10 years ago
Péter Szilágyi	6def110c37	cmd/bootnode, eth, p2p, p2p/discover: clean up the seeder and mesh into eth.	10 years ago
Péter Szilágyi	5f735d6fce	cmd, eth, p2p, p2p/discover: init and clean up the seed cache	10 years ago
Felix Lange	635b66acdc	p2p: return zero node from Self if the server is not running ... This helps with fixing the tests for cmd/geth to run without networking.	10 years ago
Felix Lange	5528abc795	p2p: fix the dial timer ... The dial timer was not reset properly when the peer count reached MaxPeers.	10 years ago
obscuren	474aa924ca	p2p: added limiter function to limit package broadcasting	10 years ago
Felix Lange	b9929d289d	p2p: fix unsynchronized map access during Server shutdown ... removePeer can be called even after listenLoop and dialLoop have returned.	10 years ago
Felix Lange	c5332537f5	p2p: limit number of lingering inbound pre-handshake connections ... This is supposed to apply some back pressure so Server is not accepting more connections than it can actually handle. The current limit is 50. This doesn't really need to be configurable, but we'll see how it behaves in our test nodes and adjust accordingly.	10 years ago
Felix Lange	56977c225e	p2p: use RLock instead of Lock for pre-dial checks	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	145330fdf2	p2p: properly decrement peer wait group counter for setup errors	10 years ago
Felix Lange	22d1f0faf1	p2p: improve peer selection logic ... This commit introduces a new (temporary) peer selection strategy based on random lookups. While we're here, also implement the TODOs in dialLoop.	10 years ago
obscuren	688d118c7e	Updated logging	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

zelig	e150832734	p2p: server>discover table Self=Node exported	10 years ago
Taylor Gerring	485e37e889	Move MakeName to ethutil	10 years ago
Taylor Gerring	9723191b19	Undo client_version changes	10 years ago
Felix Lange	215c763d53	eth, p2p: delete p2p.Blacklist ... It is unused and untested right now. We can bring it back later if required.	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
