When blocks and attestations arrive, they are SSZ-decoded twice: once
for validation and once for processing. This branch enqueues the decoded
block directly for processing, avoiding the second, slow
deserialization.
* move processing of blocks and attestations to queue
* ...and out from beacon_node
* split attestation processing into attestations and aggregates
* also updates metrics
* clean up logging to better follow the lifetime of gossip: arrival,
validation and processing
* drop attestations and aggregates if there are too many
* try to prioritise blocks and aggregates before single-validator
attestations
removed in 0.12.2 - the flow, in particular when the other peer doesn't
support snappy, is hard to follow because of the trial-and-error
approach - removing it simplifies things and removes some of the
hard-to-read parts of the thunking etc
this resolves some peer counting issues that were happening because the
lifetime future in PeerInfo was unreliable (multiple PeerInfo instances
existed per peer)
In addition, this solves another race condition: when connecting to a
peer and later dialling that protocol, it is not certain that the same
connection will be used if there's a concurrent incoming peer connection
ongoing - better not make too many assumptions about who sent statuses
when.
* more fork-choice fixes
* use target block/epoch to validate attestations
* make addLocalValidators sync
* add current and previous epoch to cache before doing state transition
* update head state using clearance state as a shortcut, when possible
* use blockslot for fork choice balances
* send attestations using epochref cache
* fix invalid finalized parent being used
also simplify epoch block traversal
* single error handling style in fork choice
* import fix, remove unused async
* avoid converting from uint64 to int, and where most feasible, int type conversion at all
* .len.uint64 -> .len64
* fix 32-bit compilation
* try keeping state_sim loop variable/bounds as int for 32-bit Azure
* len64 -> lenu64
* don't kill the program if not connected to a bootstrap node within 30 seconds
* recover faster from loss of network connectivity
* connectWorker(): sleep 1s between dials
* launch_local_testnet.sh: increase BOOTSTRAP_TIMEOUT
* don't use metric value in program logic
* refactor some ungainly variable names
* cleanups
* fix ncli state root check flag
* add block dump to ncli_db
* limit ncli_db benchmark length
* tone down finalization logs
* introduce trusted blocks
We only store blocks whose signature we've verified in the database - as
such, there's no need to check it again, and most importantly, no need
to deserialize the signature when loading from database.
50x startup time improvement, 200x block load time improvement.
* fix rewinding when deposits have invalid signature
* speed up ancestor iteration by avoiding copy
* avoid deserializing signatures for trusted data
* load blocks lazily when rewinding (less memory used)
* chronicles workarounds
* document trustedbeaconblock
* reorder ssz
* split into hash_trees and ssz_serialization, roughly, for hashing and
IO
* move bitseqs into ssz (from stew)
* clean up imports
* docs, imports
