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	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.	9 years ago
