| | | | | With the Ethereum Homestead fork is now behind us, we can assume that everyone runs an EIP-8 capable client.

* | all: fix license headers one more timeFelix Lange2015-07-241-1/+1
| | | | | | | | I forgot to update one instance of "go-ethereum" in commit 3f047be5a.
* | all: update license headers to distiguish GPL/LGPLFelix Lange2015-07-231-4/+4
|/ | | | | All code outside of cmd/ is licensed as LGPL. The headers now reflect this by calling the whole work "the go-ethereum library".

* p2p: new dialer, peer management without locksFelix Lange2015-05-251-4/+440
| | | | | | | | | | | | | | | | | | 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.
* p2p: reject messages that cannot be written as simple RLPx framesFelix Lange2015-03-041-0/+5
| | | | | Until chunked frames are implemented we cannot send messages with a size overflowing uint24.
* p2p: restore read/write timeoutsFelix Lange2015-03-041-0/+5
| | | | They got lost in the transition to rlpxFrameRW.
