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
use a separate process for the private keys (Off by default) - there is a new signing_process binary which loads all validators of the beacon node and the BN dictates through stdin of the signing process what to be signed and when and reads from stdout of the process

# Local modules
- 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

# Metrics
Fork choice fixes 5 (#1381) * limit attestations kept in attestation pool With fork choice updated, the attestation pool only needs to keep track of attestations that will eventually end up in blocks - we can thus limit the horizon of attestations that we keep more aggressively. To get here, we expose getEpochRef which gets metadata about a particular epochref, and make sure to populate it when a block is added - this ensures that state rewinds during block addition are minimized. In addition, we'll use the target root/epoch when validating attestations - this helps minimize the number of different states that we need to rewind to, in general. * remove CandidateChains.justifiedState unused * remove BlockPools.Head object * avoid quadratic quarantine loop * fix
