# Common routines for a BeaconNode and a BeaconValidator node
import
first batch of work towards the VC/BN split: - we have a new binary which connects via RPC to the respective BN and has an internal clock - waking it up on every slot - the BN has a new option called --external-validators and currently in order to have the VC binaries to run we need to pass EXTERNAL_VALIDATORS=yes to make - factored some code out of beacon_node.nim for easier reuse in validator_api.nim and validator_client.nim - the VC loads its associated private keys from the datadir for its BN - most of the validator API calls have been implemented as a stub. - the VC polls its BN at the start of each epoch - getting a list of all active validators for the current epoch - and then continues to request blocks and sign them with its appropriate validators when necessary
2020-05-22 17:04:52 +00:00
# Standard library
- extracted the commands to run a VC into a separate run_validator.sh script - each BN gets half of its previous validators as inProcess and the other half goes to the respective VC for that BN - using separate data dirs where the keys are copied - also removed a few command line options which are no longer necessary - block proposals originating from a VC are propagated from one BN to the rest properly - other cleanup & moving code back to since it is no longer used elsewhere

Add proper concurrent connections. Add SeenTable to avoid continuous attempts to dead peers. Refactor onSecond. Block backward sync while forward sync is working. SyncManager now checks responses according corresponding requests + tests. SyncManager now watching for not progressing local_head_slot and resets SyncQueue.

more work on the BN/VC split - fixed comments from the last review - getting more data VIA RPC, moved some code back into the BN only - attestation duties being requested as well
