fix slashing db interchange test compile warnings (#2311) 2021-02-11 13:54:54 +01:00
Mamy Ratsimbazafy

Slashing protection refactor - EIP 3076 (#2094) 
* Create CLI tool for slashing export

* Use SQLite as a DB instead of a KV-store

* Keeps v1 and v2 DBs around

* Uses the same schema as Lighthouse v1.1.0

* Passes all interchange tests + skeleton of finalization pruning

* Removes tests that would violate v5 / minimal slashing DB and MinSlot rules

* Migration tool added using low-watermark scheme for faster migration of large number of validators

Block validation flow v2 + Batch (serial) sig verification (#2250) 
* bump nim-blscurve

* Outline the block validation flow

* introduce the SigVerified types, pass the tests

* Split clearance/quarantine to prepare for batch crypto verif

* Add a batch signature collector

* Make clearance use SigVerified block and split verification between crypto and state transition

* Always use signedBeaconBlock for the onBlockAdded callback

* RANDAO signing_root is the epoch instead of the full block

* Support skipping BLS for testing

* Fix compilation of the validator client

* Try to fix strange errors MacOS and Jenkins (Clang, unknown type name br_hmac_drbg_context in stdlib_assertions.nim.c)

* Improve codegen of conversion zero-cost)

* Quick fixes with loadWithCache after #2259 (TODO: graceful error since pubkey validations is now done first in signatures_batch)

* Graceful handle rogue pubkeys and signatures now that those are lazy-loaded

performance fixes (#2259) 
* performance fixes

* don't mark tree cache as dirty on read-only List accesses
* store only blob in memory for keys and signatures, parse blob lazily
* compare public keys by blob instead of parsing / converting to raw
* compare Eth2Digest using non-constant-time comparison
* avoid some unnecessary validator copying

This branch will in particular speed up deposit processing which has
been slowing down block replay.

fc7885b27e Store block summary in database 
This introcudes a cache for block summaries, useful for instantiating
the block dag on startup, bringing medalla startup times down from
minutes to seconds.

This is something of a temporary band-aid that would be obsoleted by a

7c0b4d28d2 speed up reward/penalty calculation 
Calculating rewards/penalties is slow due to how we compute sets of
attestations validators then use the sets for inclusion checks, to see
who attested. The dominant function during validated block processing /
epoch processing is hash set building and lookup.

This PR inverts the flow by removing the sets and creating a single
large validator status list, then applying all relevant state
attestations, then updating rewards and penalties.

This provides a 10x speedup to epoch processing which in turn speeds up
both empty slot and block processing - for example, on startup, we
replay all non-finalized blocks to prime fork choice - the same when
validating attestations or replaying states on reorg.
