## Issue Addressed
Fix a bug introduced by #3696. The bug is not expected to occur frequently, so releasing this PR is non-urgent.
## Proposed Changes
* Add a variant to `StoreOp` that allows a raw KV operation to be passed around.
* Return to using `self.store.do_atomically` rather than `self.store.hot_db.do_atomically`. This streamlines the write back into a single call and makes our auto-revert work again.
* Prevent `import_block_update_shuffling_cache` from failing block import. This is an outstanding bug from before v3.4.0 which may have contributed to some random unexplained database corruption.
## Additional Info
In #3696 I split the database write into two calls, one to convert the `StoreOp`s to `KeyValueStoreOp`s and one to write them. This had the unfortunate side-effect of damaging our atomicity guarantees in case of a write error. If the first call failed, we would be left with the block in fork choice but not on-disk (or the snapshot cache), which would prevent us from processing any descendant blocks. On `unstable` the first call is very unlikely to fail unless the disk is full, but on `tree-states` the conversion is more involved and a user reported database corruption after it failed in a way that should have been recoverable.
Additionally, as @emhane observed, #3696 also inadvertently removed the import of the new block into the block cache. Although this seems like it could have negatively impacted performance, there are several mitigating factors:
- For regular block processing we should almost always load the parent block (and state) from the snapshot cache.
- We often load blinded blocks, which bypass the block cache anyway.
- Metrics show no noticeable increase in the block cache miss rate with v3.4.0.
However, I expect the block cache _will_ be useful again in `tree-states`, so it is restored to use by this PR.

## Proposed Changes
Our `ERRO` stream has been rather noisy since the merge due to some unexpected behaviours of builders and EEs. Now that we've been running post-merge for a while, I think we can drop some of these `ERRO` to `WARN` so we're not "crying wolf".
The modified logs are:
#### `ERRO Execution engine call failed`
I'm seeing this quite frequently on Geth nodes. They seem to timeout when they're busy and it rarely indicates a serious issue. We also have logging across block import, fork choice updating and payload production that raise `ERRO` or `CRIT` when the EE times out, so I think we're not at risk of silencing actual issues.
#### `ERRO "Builder failed to reveal payload"`
In #3775 we reduced this log from `CRIT` to `ERRO` since it's common for builders to fail to reveal the block to the producer directly whilst still broadcasting it to the networ. I think it's worth dropping this to `WARN` since it's rarely interesting.
I elected to stay with `WARN` since I really do wish builders would fulfill their API promises by returning the block to us. Perhaps I'm just being pedantic here, I could be convinced otherwise.
#### `ERRO "Relay error when registering validator(s)"`
It seems like builders and/or mev-boost struggle to handle heavy loads of validator registrations. I haven't observed issues with validators not actually being registered, but I see timeouts on these endpoints many times a day. It doesn't seem like this `ERRO` is worth it.
#### `ERRO Error fetching block for peer ExecutionLayerErrorPayloadReconstruction`
This means we failed to respond to a peer on the P2P network with a block they requested because of an error in the `execution_layer`. It's very common to see timeouts or incomplete responses on this endpoint whilst the EE is busy and I don't think it's important enough for an `ERRO`. As long as the peer count stays high, I don't think the user needs to be actively concerned about how we're responding to peers.

## Description
We were missing an edge case when checking to see if a block is a descendant of the finalized checkpoint. This edge case is described for one of the tests in this PR:
a119edc739/consensus/proto_array/src/proto_array_fork_choice.rs (L1018-L1047)
This bug presented itself in the following mainnet log:
```
Jan 26 15:12:42.841 ERRO Unable to validate attestation error: MissingBeaconState(0x7c30cb80ec3d4ec624133abfa70e4c6cfecfca456bfbbbff3393e14e5b20bf25), peer_id: 16Uiu2HAm8RPRciXJYtYc5c3qtCRdrZwkHn2BXN3XP1nSi1gxHYit, type: "unaggregated", slot: Slot(5660161), beacon_block_root: 0x4a45e59da7cb9487f4836c83bdd1b741b4f31c67010c7ae343fa6771b3330489
```
Here the BN is rejecting an attestation because of a "missing beacon state". Whilst it was correct to reject the attestation, it should have rejected it because it attests to a block that conflicts with finality rather than claiming that the database is inconsistent.
The block that this attestation points to (`0x4a45`) is block `C` in the above diagram. It is a non-canonical block in the first slot of an epoch that conflicts with the finalized checkpoint. Due to our lazy pruning of proto array, `0x4a45` was still present in proto-array. Our missed edge-case in [`ForkChoice::is_descendant_of_finalized`](38514c07f2/consensus/fork_choice/src/fork_choice.rs (L1375-L1379)) would have indicated to us that the block is a descendant of the finalized block. Therefore, we would have accepted the attestation thinking that it attests to a descendant of the finalized *checkpoint*.
Since we didn't have the shuffling for this erroneously processed block, we attempted to read its state from the database. This failed because we prune states from the database by keeping track of the tips of the chain and iterating back until we find a finalized block. This would have deleted `C` from the database, hence the `MissingBeaconState` error.
## Issue Addressed
Resolves#2521
## Proposed Changes
Add a metric that indicates the next attestation duty slot for all managed validators in the validator client.
## Issue Addressed
NA
## Proposed Changes
Removes the "Participation Rate" since it references an undefined variable: `previous_epoch_attesting_gwei`.
I didn't replace it with anything since I think "Justification/Finalization Rate" already expresses what it was trying to express.
## Additional Info
NA
## Issue Addressed
Resolves the cargo-audit failure caused by https://rustsec.org/advisories/RUSTSEC-2023-0010.
I also removed the ignore for `RUSTSEC-2020-0159` as we are no longer using a vulnerable version of `chrono`. We still need the other ignore for `time 0.1` because we depend on it via `sloggers -> chrono -> time 0.1`.
## Issue Addressed
Adds self rate limiting options, mainly with the idea to comply with peer's rate limits in small testnets
## Proposed Changes
Add a hidden flag `self-limiter` this can take no value, or customs values to configure quotas per protocol
## Additional Info
### How to use
`--self-limiter` will turn on the self rate limiter applying the same params we apply to inbound requests (requests from other peers)
`--self-limiter "beacon_blocks_by_range:64/1"` will turn on the self rate limiter for ALL protocols, but change the quota for bbrange to 64 requested blocks per 1 second.
`--self-limiter "beacon_blocks_by_range:64/1;ping:1/10"` same as previous one, changing the quota for ping as well.
### Caveats
- The rate limiter is either on or off for all protocols. I added the custom values to be able to change the quotas per protocol so that some protocols can be given extremely loose or tight quotas. I think this should satisfy every need even if we can't technically turn off rate limits per protocol.
- This reuses the rate limiter struct for the inbound requests so there is this ugly part of the code in which we need to deal with the inbound only protocols (light client stuff) if this becomes too ugly as we add lc protocols, we might want to split the rate limiters. I've checked this and looks doable with const generics to avoid so much code duplication
### Knowing if this is on
```
Feb 06 21:12:05.493 DEBG Using self rate limiting params config: OutboundRateLimiterConfig { ping: 2/10s, metadata: 1/15s, status: 5/15s, goodbye: 1/10s, blocks_by_range: 1024/10s, blocks_by_root: 128/10s }, service: libp2p_rpc, service: libp2p
```
## Proposed Changes
There are some features that are enabled/disabled with the `FEATURES` env variable. This PR would introduce a pattern to introduce docker images based on those features. This can be useful later on to have specific images for some experimental features in the future.
## Additional Info
We at Lodesart need to have `minimal` spec support for some cross-client network testing. To make it efficient on the CI, we tend to use minimal preset.

## Proposed Changes
Clippy 1.67.0 put us on blast for the size of some of our errors, most of them written by me ( 👀 ). This PR shrinks the size of `BeaconChainError` by dropping some extraneous info and boxing an inner error which should only occur infrequently anyway.
For the `AttestationSlashInfo` and `BlockSlashInfo` I opted to ignore the lint as they are always used in a `Result<A, Info>` where `A` is a similar size. This means they don't bloat the size of the `Result`, so it's a bit annoying for Clippy to report this as an issue.
I also chose to ignore `clippy::uninlined-format-args` because I think the benefit-to-churn ratio is too low. E.g. sometimes we have long identifiers in `format!` args and IMO the non-inlined form is easier to read:
```rust
// I prefer this...
format!(
"{} did {} to {}",
REALLY_LONG_CONSTANT_NAME,
ANOTHER_REALLY_LONG_CONSTANT_NAME,
regular_long_identifier_name
);
// To this
format!("{REALLY_LONG_CONSTANT_NAME} did {ANOTHER_REALLY_LONG_CONSTANT_NAME} to {regular_long_identifier_name}");
```
I tried generating an automatic diff with `cargo clippy --fix` but it came out at:
```
250 files changed, 1209 insertions(+), 1469 deletions(-)
```
Which seems like a bad idea when we'd have to back-merge it to `capella` and `eip4844` 😱
## Issue Addressed
Currently there is a race between receiving blocks and receiving light client optimistic updates (in unstable), which results in processing errors. This is a continuation of PR #3693 and seeks to progress on issue #3651
## Proposed Changes
Add the parent_root to ReprocessQueueMessage::BlockImported so we can remove blocks from queue when a block arrives that has the same parent root. We use the parent root as opposed to the block_root because the LightClientOptimisticUpdate does not contain the block_root.
If light_client_optimistic_update.attested_header.canonical_root() != head_block.message().parent_root() then we queue the update. Otherwise we process immediately.
## Additional Info
michaelsproul came up with this idea.
The code was heavily based off of the attestation reprocessing.
I have not properly tested this to see if it works as intended.

We recently ran a large-block experiment on the testnet and plan to do a further experiment on mainnet.
Although the metrics recovered from lighthouse nodes were quite useful, I think we could do with greater resolution in the block delay metrics and get some specific values for each block (currently these can be lost to large exponential histogram buckets).
This PR increases the resolution of the block delay histogram buckets, but also introduces a new metric which records the last block delay. Depending on the polling resolution of the metric server, we can lose some block delay information, however it will always give us a specific value and we will not lose exact data based on poor resolution histogram buckets.

## Issue Addressed
#3853
## Proposed Changes
Added `INFO` level logs for requesting and receiving the unsigned block.
## Additional Info
Logging for successfully publishing the signed block is already there. And seemingly there is a log for when "We realize we are going to produce a block" in the `start_update_service`: `info!(log, "Block production service started");
`. Is there anywhere else you'd like to see logging around this event?

## Proposed Changes
Decouple the stdout and logfile formats by adding the `--logfile-format` CLI flag.
This behaves identically to the existing `--log-format` flag, but instead will only affect the logs written to the logfile.
The `--log-format` flag will no longer have any effect on the contents of the logfile.
## Additional Info
This avoids being a breaking change by causing `logfile-format` to default to the value of `--log-format` if it is not provided.
This means that users who were previously relying on being able to use a JSON formatted logfile will be able to continue to use `--log-format JSON`.
Users who want to use JSON on stdout and default logs in the logfile, will need to pass the following flags: `--log-format JSON --logfile-format DEFAULT`
## Issue Addressed
Issue #3112
## Proposed Changes
Add `Filter::recover` to the GET chain to handle rejections specifically as 404 NOT FOUND
## Additional Info
Making a request to `http://localhost:5052/not_real` now returns the following:
```
{
"code": 404,
"message": "NOT_FOUND",
"stacktraces": []
}
```
