Downgrade light client errors to debug
Error messages are alarming and usually indicate somethings wrong with the beacon node. The Light Client service is supposed to minimally impact users, and most will not care if the light client server is erroring. Furthermore, the only errors we've seen in the wild are during hard forks, for the first few epochs before the fork finalizes.
N/A
Return state.eth1_data() early if we have passed the transition period post electra. Even if we don't return early, the function would still return state.eth1_data() based on the current conditions. However, doing this explicitly here to match the spec. This covers setting the right eth1_data in our block.
The other thing we need to ensure is that the deposits returned by the eth1_chain is empty post transition.
The only way we get non-empty deposits post the transition is if `state.eth1_deposit_index` in the below code is less than `min(deposit_requests_start_index, state.eth1_data().deposit_count)`.
0850bcfb89/beacon_node/beacon_chain/src/eth1_chain.rs (L543-L579)
This can never happen because state.eth1_deposit_index will be equal to state.eth1_data.deposit count and cannot exceed the value.
@michaelsproul @ethDreamer please double check the logic for deposits being empty post transition. Following the logic in the spec makes my head hurt.
This is a workaround for #7216
In the case of gaps between the in-memory pub key cache and its on-disk representation, use the head state on startup to "top-up" the cache/db w/ any missing validators
Backport of:
- https://github.com/sigp/lighthouse/pull/7067
For:
- https://github.com/sigp/lighthouse/issues/7039
- Prevent writing to state cache when migrating the database
- Add `state-cache-headroom` flag to control pruning
- Prune old epoch boundary states ahead of mid-epoch states
- Never prune head block's state
- Avoid caching ancestor states unless they are on an epoch boundary
- Log when states enter/exit the cache

This change makes the `total_difficulty` field in `ExecutionBlock` an `Option<Uint256>` since newer clients are no longer including the `totalDifficulty` field.
I think this will fix https://github.com/sigp/lighthouse/issues/6937 but I was actually more focused on the builder registration case described below.
In our [builder-playground](https://github.com/flashbots/builder-playground) we setup a local devnet using lighthouse, reth, and mev-boost-relay. After upgrading to reth 1.2.0 and lighthouse v7.0.0.beta.0 for Pectra, we noticed that the validator registration process was _sometimes_ failing with:
```
Feb 25 23:35:25.038 ERRO Unable to publish proposer preparation to all beacon nodes, error: Some endpoints failed, num_failed: 1 http://localhost:3500/ => RequestFailed(ServerMessage(ErrorMessage { code: 400, message: "BAD_REQUEST: error updating proposer preparations: ForkchoiceUpdate(EngineError(Api { error: Json(Error(\"missing field `totalDifficulty`\", line: 0, column: 0)) }))", stacktraces: [] })), service: preparation
Feb 25 23:35:25.099 WARN Unable to publish validator registrations to the builder network, error: Some endpoints failed, num_failed: 1 http://localhost:3500/ => RequestFailed(ServerMessage(ErrorMessage { code: 400, message: "BAD_REQUEST: error updating proposer preparations: ForkchoiceUpdate(EngineError(Api { error: Json(Error(\"missing field `totalDifficulty`\", line: 0, column: 0)) }))", stacktraces: [] })), service: preparation
```
What was even more confusing, was that it was sometimes working, which actually led to a wild goose chase thinking it was a networking issue. However, when tracing through the LH code, I came across this comment:
70194dfc6a/beacon_node/beacon_chain/src/beacon_chain.rs (L6048-L6049)
This explained why it sometimes worked, in our playground we run lighthouse with `--prepare-payload-lookahead 8000` thus there was always a 4-second window where the call wasn't made.
But, if the call was made, then this code would 100% fail with updated reth:
https://github.com/sigp/lighthouse/blob/unstable/beacon_node/execution_layer/src/lib.rs#L1688-L1692
Which would then mapped to a `Error::ForkchoiceUpdate` in `update_execution_engine_forkchoice`.
Anyways, the fix was to make `total_difficulty` Optional, and then to update any code paths where it was used. In doing so, I assume that if the EL doesn't include total difficulty then the chain is already post-merge.
Resolves https://github.com/sigp/lighthouse/issues/7000
Set the accept header on builder to the correct value when requesting ssz.
This PR also adds a flag to disable ssz over the builder api altogether. In the case that builders/relays have an ssz bug, we can react quickly by asking clients to restart their nodes with the `--disable-ssz-builder` flag to force json. I'm not fully convinced if this is useful so open to removing it or opening another PR for it.
Testing this currently.

2 changes:
1. Replace Option::map_or(true, ...) with is_none_or(...)
2. Remove unnecessary `Into::into` blocks where the type conversion is apparent from the types
Closes:
- https://github.com/sigp/lighthouse/issues/6818
Use `MAX_EFFECTIVE_BALANCE_ELECTRA` (2048) for attestation reward calculations involving Electra.
Add a new `InteropGenesisBuilder` that tries to provide a more flexible way to build genesis states. Unfortunately due to lifetime jank, it is quite unergonomic at present. We may want to refactor this builder in future to make it easier to use.
Closes
- https://github.com/sigp/lighthouse/issues/6805
- Use a new `WorkEvent::GossipAttestationToConvert` to handle the conversion from `SingleAttestation` to `Attestation` _on_ the beacon processor (prevents a Tokio thread being blocked).
- Improve the error handling for single attestations. I think previously we had no ability to reprocess single attestations for unknown blocks -- we would just error. This seemed to be the case in both gossip processing and processing of `SingleAttestation`s from the HTTP API.
- Move the `SingleAttestation -> Attestation` conversion function into `beacon_chain` so that it can return the `attestation_verification::Error` type, which has well-defined error handling and peer penalties. The now-unused variants of `types::Attestation::Error` have been removed.
Fix another issue with fetch-blobs, similar to:
- https://github.com/sigp/lighthouse/pull/6911
Check if the list of blobs returned is all `None`, and if so, do not proceed any further.
This prevents an ugly error like:
> Feb 03 17:32:12.384 ERRO Error fetching or processing blobs from EL, block_root: 0x7326fe2dc1cb9036c9de7a07a662c86a339085597849016eadf061b70b7815ba, error: BlobProcessingError(AvailabilityCheck(Unexpected)), module

- #6510
- Keep execution payload during historical backfill when `--prune-payloads false` is set
- Add a field in the historical backfill debug log to indicate if execution payload is kept
- Add a test to check historical blocks has execution payload when `--prune-payloads false is set
- Very minor typo correction that I notice when working on this
Resolve a `TODO(das)` to use KZG batch verification in `put_rpc_custody_columns`
Uses `verify_kzg_for_data_column_list_with_scoring` in all paths that send more than one column. To use batch verification and have attributability of which peer is sending a bad column.
Needs to move `verify_kzg_for_data_column_list_with_scoring` into the type's module to convert to the KZG verified type.
Addresses #6026.
Post-PeerDAS the DB expects to have data columns for the finalized block.
Instead of forcing the user to submit the columns, this PR computes the columns from the blobs that we can already fetch from the checkpointz server or with the existing CLI options.
Note 1: (EDIT) Pruning concern addressed
Note 2: I have not tested this feature
Note 3: @michaelsproul an alternative I recall is to not require the blobs / columns at this point and expect backfill to populate the finalized block
Addresses #6706
This PR activates PeerDAS at the Fulu fork epoch instead of `EIP_7594_FORK_EPOCH`. This means we no longer support testing PeerDAS with Deneb / Electrs, as it's now part of a hard fork.

by detecting if the proposer signature is valid or not during RPC block processing. In lookup sync, if the invalid signature signature is the proposer signature, it's not deterministic on the block root. So we should only penalize the sending peer and retry. Otherwise, if it's on the body we should drop the lookup and penalize all peers that claim to have imported the block
