- Remove unnecessary `Defect` references
- Remove spurious `SerializationError` references
- Remove duplicate `writeValue` template in `keystore.nim`;
same implementation already exists a bit further above in same file.
Add separate log topic for `block_processor` messages.
Topic named similar to the other `_processor` modules:
- `eth2_processor` --> `gossip_eth2`
- `light_client_processor` --> `gossip_lc`
- `optimistic_processor` --> `gossip_opt`
In #4465, a regression was introduced by deleting the periodic call to
`engine_exchangeTransitionConfiguration` in the Nimbus light client.
This led to the light client never treating the EL as online and,
subsequently, not sending `engine_newPayload` requests for new blocks.
Strangely, `engine_forkchoiceUpdated` requests still make it through :)
Geth still requires both `engine_newPayload` and `fcU` to be called.
By restoring the `exchangeTransitionConfiguration` loop, `newPayload`
requests are once more issued to the EL.
When a block is introduced to the system both via REST and gossip at the
same time, we will call `storeBlock` from two locations leading to a
dupliace check race condition as we wait for the EL.
This issue may manifest in particular when using an external block
builder that itself publishes the block onto the gossip network.
* refactor enqueue flow
* simplify calling `addBlock`
* complete request manager verifier future for blobless blocks
* re-verify parent conditions before adding block
among other things, it might have gone stale or finalized between one
call and the other
every attestation is processed with a new wall time so we end up
iterating over all attestations for every attestation we queue - this is
4% of cpu time on a subscribe-all-subnets node
* remove redundant zero checks - block root must be an existing block
and therefore cannot be zero
* simplify "hasn't-voted" check to root only (isZeroMemory is dubiously
implemented for objects)
* Add support for POST /eth/v2/beacon/blocks
* More descriptive errors
* Address review feedback
* Return 500 (not 400) for a missing implementation case
We know the aggregate publickey of a fully participating sync committee.
Because participation is typically very high (>95%), it is faster to
start from that aggregate publickey and subtract the individual keys of
non-participants, than summing up all the participating pubkeys.
To obtain the correct `transactions_root` and `withdrawals_root`,
it is necessary to process execution block header. Light client updates
don't contain the correct MPT roots.
Using `create` with objects containing managed objects is broken:
https://github.com/nim-lang/Nim/issues/22341
Switch to a safer pattern based on `new+GC_ref`/`GC_unref` instead.
