* restore doppelganger check on connectivity loss
https://github.com/status-im/nimbus-eth2/pull/4398 introduced a
regression in functionality where doppelganger detection would not be
rerun during connectivity loss. This PR reintroduces this check and
makes some adjustments to the implementation to simplify the code flow
for both BN and VC.
* track when check was last performed for each validator (to deal with
late-added validators)
* track when we performed a doppel-detectable activity (attesting) so as
to avoid false positives
* remove nodeStart special case (this should be treated the same as
adding a validator dynamically just after startup)
* allow sync committee duties in doppelganger period
* don't trigger doppelganger when registering duties
* fix crash when expected index response is missing
* fix missing slashingSafe propagation
Other changes:
Renamed the `EIP_4844_FORK_*` config constants to `DENEB_FORK_*` as
this matches the latest spec and it's already used in the official
Sepolia config.
We do a linear scan of all pubkeys for each validator and slot - this
becomes expensive with large validator counts.
* normalise BN/VC validator startup logging
* fix crash when host cannot be resolved while adding remote validator
* silence repeated log spam for unknown validators
* print pubkey/index/activation mapping on startup/validator
identification
* debug log upon sidecar validation failure
* Fill in signature catch upon SignedBeaconBlockAndBlobsSidecar deser
* Always fill blobssidecar slot and root
* Skip lastFCU when eth1monitor is nil
* fix
* Use cached root
* eip4844 beacon block proposals
* Don't fetch blobs under minimal preset
@tersec's summary of the issue:
BlobsBundleV1 in the execution API spec assumes a mainnet preset blob
size, where the EIP4844 consensus spec defines
FIELD_ELEMENTS_PER_BLOB: 4 under the minimal preset, which leads to a
Blob having a length of 4 * 32, not 4096 * 32 which BlobsBundleV1
requires.
* Revert unintentional script change
* exit/validatorchange pool includes BLS to execution messages; REST
support for new pool
* catch failed individual futures
* increase BLS changes bound and keep BLS seen consistent with subpool
* deque capacities should be powers of 2
* Refactor block/blobs types
Use type system to enforce invariant that a pre-4844 block cannot have
a sidecar.
* Update beacon_chain/nimbus_beacon_node.nim

By enabling the validator monitor, more precise information about the
lifecycle of an attestation is logged at the higher `NOTICE` log level
while current `sent` messages are logged at `INF` instead, since they
are less interesting.
In particular, missed attestations and those that vote for the wrong
head are now detected and logged at NOTICE.
In addition to logging, this feature enables rich metrics around
attestation and sync committee performance - by default, validators are
tracked in aggregate but a detailed mode exists as well
This feature has been available since early Nimbus days, but it has now
been tuned and optimised such that it is safe to enable by default, even
for large setups.
* enable automatic validator monitoring by default
* replace `--validator-monitor-totals` flag with
`--validator-monitor-details` - the detailed mode is disabled by default
* lower "sent" log level to `INF` for several messages - in particular
those that are traced by the validator monitor
This is a retake on #3531 which was later reverted in #3578.
Distinguish between those code locations that need to be updated on each
light client data format change, and those others that should generally
be fine, as long as a valid light client object is processed.
The former are tagged with static assert for `LightClientDataFork.high`.
The latter are changed to `lcDataFork > LightClientDataFork.None` to
indicate that they depend only on presence of any valid object.
Also bundled a few minor cleanups and fixes.
Also add `Forky` type for `LightClientStore` and minor fixes / cleanups.
The light client data structures were changed to accommodate additional
fields in future forks (e.g., to also hold execution data).
There is a minor change to the JSON serialization, where the `header`
properties are now nested inside a `LightClientHeader`.
The SSZ serialization remains compatible.
See https://github.com/ethereum/consensus-specs/pull/3190
and https://github.com/ethereum/beacon-APIs/pull/287
In a future fork, light client data will be extended with execution info
to support more use cases. To anticipate such an upgrade, introduce
`Forky` and `Forked` types, and ready the database schema.
Because the mapping of sync committee periods to fork versions is not
necessarily unique (fork schedule not in sync with period boundaries),
an additional column is added to `period` -> `LightClientUpdate` table.
* fix REST liveness endpoint responding even when gossip is not enabled
* fix VC exit code on doppelganger hit
* fix activation epoch not being updated correctly on long deposit
queues
* fix activation epoch being set incorrectly when updating validator
* move most implementation logic to `validator_pool`, add tests
* ensure consistent logging between VC and BN
* add docs
