* use v1.1.6 test vectors; use BeaconTime instead of Slot in fork choice
* tick through every slot at least once
* use div INTERVALS_PER_SLOT and use precomputed constants of them
* use correct (even if numerically equal) constant
Introduced in #3171, it turns out we can just follow the block headers
to achieve the same effect
* leaves the constant in the code so as to avoid confusion when reading
database that had the constant written (such as the fleet nodes and
other unstable users)
Validator monitoring based on and mostly compatible with the
implementation in Lighthouse - tracks additional logs and metrics for
specified validators so as to stay on top on performance.
The implementation works more or less the following way:
* Validator pubkeys are singled out for monitoring - these can be
running on the node or not
* For every action that the validator takes, we record steps in the
process such as messages being seen on the network or published in the
API
* When the dust settles at the end of an epoch, we report the
information from one epoch before that, which coincides with the
balances being updated - this is a tradeoff between being correct
(waiting for finalization) and providing relevant information in a
timely manner)
This updates `nim-ssz-serialization` to
`3cd8d2d6b80bde0ce7f25609cb5cb9fc37852fe2`.
Notable changes:
- Serialization of object variant (case object) to/from SSZ Union.
- int -> int64 fix in hashTreeRootCached
* SyncManager cleanups for backfill support
Cleanups, fixes and simplifications, in anticipation of backfill support
for the `SyncManager`:
* reformat sync progress indicator to show time left and % done more
prominently:
* old: `sync="sPssPsssss:2:2.4229:00h57m (2706898)"`
* new: `sync="14d12h31m (0.52%) 1.1378slots/s (wQQQQQDDQQ:1287520)"`
* reset average speed when going out of sync
* pass all block errors to sync manager, including duplicate/unviable
* penalize peers for reporting a head block that is outside of our
expected wall clock time (they're likely on a different network or
trying to disrupt sync)
* remove `SyncFailureKind` (unused)
* remove `inRange` (unused)
* add `Q` for sync queue requests that are in the `SyncQueue` but not
yet in the `BlockProcessor` queue
* update last slot in `SyncQueue` after getting peer status
* fix race condition between `wakeupWaiters` and `resetWait`, where
workers would not be correctly reset if block verification returned a
completed future without event loop
* log syncmanager direction
* Fix ordering issue.
Some of the requests size of which are not equal to `chunkSize` could be processed in wrong order which could lead to sync process freezes.

PBKDF2 based keystore files are required to have `dklen >= 32`.
This patch ensures that keystores not fulfilling that requirement
are properly rejected.
This updates `nim-confutils` to
`6a56d01381f434d5fbcc61b6e497b9409155bcbc`.
Notable changes:
- feature: separator text when displaying help
- feature: multiple lines long description
- feature: add ignore property in addition to hidden
- add compile time check to detect duplicate abbr and duplicate name
This updates `nim-eth` to `5655bd035cfd7319c6f2e60b7fdefef65a057939`.
Notable changes:
- db: Allow Sqlite keystores to be used in read-only mode
- net: avoid allocation in hash(ValidIpAddress)
- net: Remove hashData usage on objects
- p2p: reject WHOAREYOU packets with non-empty message
- p2p: Adjust logging when node is not reachable but enrAutoUpdate is on
- p2p: Allow a node to self resolve
- p2p: Fix logDistance for BE arch and remove toBytes for NodeId
- p2p: Export discovery routing table and its buckets nodes
- ssz: remove outdated and incorrect SSZ code
- utp: Various updates and fixes
In the ChainDAG, 3 block pointers are kept: genesis, tail and head. This
PR adds one more block pointer: the backfill block which represents the
block that has been backfilled so far.
When doing a checkpoint sync, a random block is given as starting point
- this is the tail block, and we require that the tail block has a
corresponding state.
When backfilling, we end up with blocks without corresponding states,
hence we cannot use `tail` as a backfill pointer - there is no state.
Nonetheless, we need to keep track of where we are in the backfill
process between restarts, such that we can answer GetBeaconBlocksByRange
requests.
This PR adds the basic support for backfill handling - it needs to be
integrated with backfill sync, and the REST API needs to be adjusted to
take advantage of the new backfilled blocks when responding to certain
requests.
Future work will also enable moving the tail in either direction:
* pruning means moving the tail forward in time and removing states
* backwards means recreating past states from genesis, such that
intermediate states are recreated step by step all the way to the tail -
at that point, tail, genesis and backfill will match up.
* backfilling is done when backfill != genesis - later, this will be the
WSS checkpoint instead
As of https://github.com/status-im/nim-eth/pull/379 `nim-eth` defines a
couple static test cases for merkle proof verification.
Since the EF has defined a `is_valid_merkle_branch` function in the spec
we are no longer using the custom implementation from `nim-eth`, but the
tests were never ported to target the new implementation. This patch now
follows up on that and integrates those tests from `nim-eth`.
There are multiple copies of `bitseqs` (`nim-stew`, `nim-eth`, and
`nim-ssz-serialization`). To avoid confusion, this patch removes the
final remaining reference of a non-`nim-ssz-serialization` copy.
Makes `readSszForkedTrustedSignedBeaconBlock` consistent with
`readSszForkedHashedBeaconState`, adjusting the length check
to verify the same type that is used for length computation,
and using the same formatting.
* BlockId reform
Introduce `BlockId` that helps track a root/slot pair - this prepares
the codebase for backfilling and handling out-of-dag blocks
* move block dag code to separate module
* fix finalised state root in REST event stream
* fix finalised head computation on head update, when starting from
checkpoint
* clean up chaindag init
* revert `epochAncestor` change in introduced in #3144 that would return
an epoch ancestor from the canoncial history instead of the given
history, causing `EpochRef` keys to point to the wrong block
In #780 a test was disabled that verified that an attestation with
empty `aggregation_bits` completes successfully. The test was never
re-introduced, and as of the current consensus spec v1.1.6, such
attestations are not considered valid, as they fail the check in
`is_valid_indexed_attestation`. This patch fully removes that outdated
test, and moves it to the list of pending invalid attestation tests.
* batch-verify sync messages for a small perf boost
Generally reuses the same structure as attestation and aggregate
verification
* normalize `signatures` and `signature_batch` to use the same pattern
of verification
* normalize parameter names, order etc for signature stuff in general
* avoid calling `blsSign` directly - instead, go through `signatures`
consistently
This removes some dead code from `getSubcommitteePositionsAux` which is
no longer needed since the introduction of `SyncCommitteeCache`.
This also cleans up some formatting, uses `let` instead of `var` where
possible, and uses implicit `pairs` in one case for consistency.
