Just the variable, not yet `lcDataForkAtStateFork` / `atStateFork`.
- Shorten comment in `light_client.nim` to keep line width
- Do not rename `stateFork` mention in `runProposalForkchoiceUpdated`.
- Do not rename `stateFork` in `getStateField(dag.headState, fork)`
Rest is just a mechanical mass replace
When using `--history=prune`, `dag.tail.slot` may advance beyond the
configured light client data retention period. Update the LC logic so
that the `dag.tail.slot` is no longer considered for LC pruning.
It is still considered to check whether new data can be produced.
* Support for driving multiple EL nodes from a single Nimbus BN
Full list of changes:
* Eth1Monitor has been renamed to ELManager to match its current
responsibilities better.
* The ELManager is no longer optional in the code (it won't have
a nil value under any circumstances).
* The support for subscribing for headers was removed as it only
worked with WebSockets and contributed significant complexity
while bringing only a very minor advantage.
* The `--web3-url` parameter has been deprecated in favor of a
new `--el` parameter. The new parameter has a reasonable default
value and supports specifying a different JWT for each connection.
Each connection can also be configured with a different set of
responsibilities (e.g. download deposits, validate blocks and/or
produce blocks). On the command-line, these properties can be
configured through URL properties stored in the #anchor part of
the URL. In TOML files, they come with a very natural syntax
(althrough the URL scheme is also supported).
* The previously scattered EL-related state and logic is now moved
to `eth1_monitor.nim` (this module will be renamed to `el_manager.nim`
in a follow-up commit). State is assigned properly either to the
`ELManager` or the to individual `ELConnection` objects where
appropriate.
The ELManager executes all Engine API requests against all attached
EL nodes, in parallel. It compares their results and if there is a
disagreement regarding the validity of a certain payload, this is
detected and the beacon node is protected from publishing a block
with a potential execution layer consensus bug in it.
The BN provides metrics per EL node for the number of successful or
failed requests for each type Engine API requests. If an EL node
goes offline and connectivity is resoted later, we report the
problem and the remedy in edge-triggered fashion.
* More progress towards implementing Deneb block production in the VC
and comparing the value of blocks produced by the EL and the builder
API.
* Adds a Makefile target for the zhejiang testnet
* Local sim impovements
* Added support for running Capella and EIP-4844 simulations
by downloading the correct version of Geth.
* Added support for using Nimbus remote signer and Web3Signer.
Use 2 out of 3 threshold signing configuration in the mainnet
configuration and regular remote signing in the minimal one.
* The local testnet simulation can now use a payload builder.
This is currently not activated in CI due to lack of automated
procedures for installing third-party relays or builders.
You are adviced to use mergemock for now, but for most realistic
results, we can create a simple builder based on the nimbus-eth1
codebase that will be able to propose transactions from the regular
network mempool.
* Start the simulation from a merged state. This would allow us
to start removing pre-merge functionality such as the gossip
subsciption logic. The commit also removes the merge-forcing
hack installed after the TTD removal.
* Consolidate all the tools used in the local simulation into a
single `ncli_testnet` binary.
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.
By pre-seeding the sync committee cache when applying blocks, we avoid a
significantly expensive validator set traversal / sync committee index
construction during sync / block application - 20-30% sync speedup
post-altair.
* also cache/reload total active balance for another cool 10%
Extends fork choice state to also track slot numbers to improve accuracy
of `/eth/v1/debug/fork_choice` endpoint. Autoenable this API on devnet,
and disable some extra checks on devnet to aid focused testing efforts.
Align fork choice pruning logic with API based on checkpoints vs root.
* clean up some Nim 1.2 workarounds
* re-add notes about JS backend
* another proc/noSideEffect -> func
* revert ncli/ncli_common.nim changes; 19969 evidently wasn't backported to 1.6
To allow LC data retention longer than the one for historic states,
introduce persistent DB caches for `current_sync_committee` and
`LightClientHeader` for finalized epoch boundary blocks.
This way, historic `LightClientBootstrap` requests may still be honored
even after pruning. Note that historic `LightClientUpdate` requests are
already answered using fully persisted objects, so don't need changes.
Sync committees and headers are cached on finalization of new data.
For existing data, info is lazily cached on first access.

When the epoch boundary block is missed, we incorrectly assume that the
next couple blocks improve finality, leading to repeated pushes of the
same light client finality update and incorrectly ignoring some gossip.
