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 This patch fully removes that outdated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.
* RPM/DEB for systemd-based systems
Similar to https://github.com/status-im/nimbus-eth2/pull/2691, this PR
introduces packaging for nimbus beacon node.
Instead of relying on interactive prompts, a default configuration is
included that connects to mainnet and expects there to be an execution
client running with websockets enabled on the same host, on the standard
websocket port.
Should the user need to configure their nimbus after installation (for
example with a different web3 url), the "standard" way of doing so via
`systemctl` edit is recommended.
* Introduce slot->BlockRef mapping for finalized chain
The finalized chain is linear, thus we can use a seq to lookup blocks by
slot number.
Here, we introduce such a seq, even though in the future, it should
likely be backed by a database structure instead, or, more likely, a
flat era file with a flat lookup index.
This dramatically speeds up requests by slot, such as those coming from
the REST interface or GetBlocksByRange, as these are currently served by
a linear iteration from head.
* fix REST block requests to not return blocks from an earlier slot when
the given slot is empty
* fix StateId interpretation such that it doesn't treat state roots as
block roots
* don't load full block from database just to return its root
This PR fixes two issues with block publishing:
* Gossip-valid blocks are published before integrating them into the
chain, giving broadcasting a head start, both for rest block and
* Outright invalid blocks from the API that could lead to the descoring
of the node are no longer broadcast
Bonus:
* remove undocumented and duplicated `post_v1_validator_block` JSON-RPC
call
* move quarantine outside of chaindag
The quarantine has been part of the ChainDAG for the longest time, but
this design has a few issues:
* the function in which blocks are verified and added to the dag becomes
reentrant and therefore difficult to reason about - we're currently
using a stateful flag to work around it
* quarantined blocks bypass the processing queue leading to a processing
stampede
* the quarantine flow is unsuitable for orphaned attestations - these
should also should be quarantined eventually
Instead of processing the quarantine inside ChainDAG, this PR moves
re-queueing to `block_processor` which already is responsible for
dealing with follow-up work when a block is added to the dag
This sets the stage for keeping attestations in the quarantine as well.
Also:
* make `BlockError` `{.pure.}`
* avoid use of `ValidationResult` in block clearance (that's for gossip)
* Add some indicators to help fixing issue.
* Bump presto to help debugging.
* Fix compilation problems in presto.
* Fix SIGSEGV.
* Bump latest changes in chronos and presto.
Fix rare cases in validator_client.
* Use proper commits for chronos and presto.
Used during initial development of the spec, `nbench` has fallen behind
and by and large been superceded by `block_sim`, `state_sim` and
`ncli_db bench`.
This extends the `makeTestBlocks` function used in tests with a new
parameter `syncCommitteeRatio` to control whether the produced blocks
should be signed by the validators assigned to the sync committee.
A similar parameter already exists to configure whether attestations
for the test blocks should be produced.
Some `LightClientUpdate` documentation of the spec is meant to span
multiple fields but was attached to a single, incorrect field in Nimbus.
This patch moves affected documentation to correct locations.
This allows `blockchain_dag`'s `withState` template to be called more
than once in a single function. This led to a compilation error before
because the injected variables and functions shared the same scope.
Validator clients such as Vouch can be configured to work with multiple
beacon nodes simultaneously. In this configuration, the validator client
will try to broadcast the gossip messages through each of the connected
beacon nodes which may lead to a situation where some of the nodes see a
message arriving from the network before it arrives through the REST API.
This should not be considered an error and the beacon node should still
broadcast the message as the intented purpose of the Vouch strategy is
to ensure that the message will reach as many peers as possible.
Turning uncompressed pubkeys into cooked ones is fast, but unnecessary -
this should avoid a little work for every signature validation we do by
pre-loading them at startup.
* add EF fork choice tests to CI
* checkpoints
* compilation fixes and add test to preset dependent suite
* support longpaths on Windows CI
* skip minimal tests (long paths issue + impl detals tested)
* fix stackoverflow on some platforms
* rebase on top of https://github.com/status-im/nimbus-eth2/pull/3054
* fix stack usage
