This adds a simulator object with implements the SentryServer api but takes objects from a pre-existing snapshot file. If the snapshot is not available locally it will download and index the .seg file for the header range being asked for. It is created as follows: ```go sim, err := simulator.NewSentry(ctx, "mumbai", dataDir, 1, logger) ``` Where the arguments are: * ctx - a callable context where cancel will close the simulator torrent and file connections (it also has a Close method) * chain - the name of the chain to take the snapshots from * datadir - a directory potentially containing snapshot .seg files. If not files exist in this directory they will be downloaded * num peers - the number of peers the simulator should create * logger - the loger to log actions to It can be attached to a client as follows: ```go simClient := direct.NewSentryClientDirect(66, sim) ``` At the moment only very basic functionality is implemented: * get headers will return headers by range or hash (hash assumes a pre-downloaded .seg as it needs an index * the header replay semantics need to be confirmed * eth 65 and 66(+) messaging is supported * For details see: `simulator_test.go More advanced peer behavior (e.g. header rewriting) can be added Bodies/Transactions handling can be added |
