Felix Lange	dcae0d348b	p2p/simulations: fix a deadlock and clean up adapters (#17891) ... This fixes a rare deadlock with the inproc adapter: - A node is stopped, which acquires Network.lock. - The protocol code being simulated (swarm/network in my case) waits for its goroutines to shut down. - One of those goroutines calls into the simulation to add a peer, which waits for Network.lock. The fix for the deadlock is really simple, just release the lock before stopping the simulation node. Other changes in this PR clean up the exec adapter so it reports node startup errors better and remove the docker adapter because it just adds overhead. In the exec adapter, node information is now posted to a one-shot server. This avoids log parsing and allows reporting startup errors to the simulation host. A small change in package node was needed because simulation nodes use port zero. Node.{HTTP,WS}Endpoint now return the live endpoints after startup by checking the TCP listener.	6 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
