## Issue Addressed
We've had a report of sync committee performance suffering with the beacon processor HTTP API prioritisations.
## Proposed Changes
Increase the priority of `/eth/v1/beacon/blocks/head/root` requests, which are used by the validator client to form sync committee messages, here:
441fc1691b/validator_client/src/sync_committee_service.rs (L181-L188)
Additionally, avoid loading the blinded block in all but the `block_id=block_root` case. I'm not sure why we were doing this previously, I suspect it was just an oversight during the implementation of the `finalized` status on API requests.
## Additional Info
I think this change should have minimal negative impact as:
- The block root endpoint is quick to compute (a few ms max).
- Only the priority of `head` requests is increased. Analytical processes that are making lots of block root requests for past slots are unable to DoS the beacon processor, as their requests will still be processed after attestations.

## Proposed Changes

## Additional Info

## Proposed Changes
This PR adds more logging prior to genesis, particularly on networks that start with execution enabled.
There are new checks using `eth_getBlockByHash/Number` to verify that the genesis state's `latest_execution_payload_header` matches the execution node's genesis block.
The first commit also runs the merge-readiness/Capella-readiness checks prior to genesis. This has two effects:
- Give more information on the execution node's status and its readiness for genesis.
- Prevent the `el_offline` status from being set on `/eth/v1/node/syncing`, which previously caused the VC to complain loudly.
I would like to include this for the Holesky reboot. It would have caught the misconfig that doomed the first Holesky.
## Additional Info
- Geth doesn't serve payload bodies prior to genesis, which is why we use the legacy methods. I haven't checked with other ELs yet.
- Currently this is logging errors with _Capella_ genesis states generated by `ethereum-genesis-generator` because the `withdrawals_root` is not set correctly (it is 0x0). This is not a blocker for Holesky, as it starts from Bellatrix (Pari is investigating).
## Issue Addressed
CI is plagued by `AddrAlreadyInUse` failures, which are caused by race conditions in allocating free ports.
This PR removes all usages of the `unused_port` crate for Lighthouse's HTTP API, in favour of passing `:0` as the listen address. As a result, the listen address isn't known ahead of time and must be read from the listening socket after it binds. This requires tying some self-referential knots, which is a little disruptive, but hopefully doesn't clash too much with Deneb 🤞
There are still a few usages of `unused_tcp4_port` left in cases where we start external processes, like the `watch` Postgres DB, Anvil, Geth, Nethermind, etc. Removing these usages is non-trivial because it's hard to read the port back from an external process after starting it with `--port 0`. We might be able to do something on Linux where we read from `/proc/`, but I'll leave that for future work.
## Issue Addressed
#4402
## Proposed Changes
This PR adds QUIC support to Lighthouse. As this is not officially spec'd this will only work between lighthouse <-> lighthouse connections. We attempt a QUIC connection (if the node advertises it) and if it fails we fallback to TCP.
This should be a backwards compatible modification. We want to test this functionality on live networks to observe any improvements in bandwidth/latency.
NOTE: This also removes the websockets transport as I believe no one is really using it. It should be mentioned in our release however.

* Update comments and small cleanup.
* Deserialize into `SsePayloadAttributesV3` for Deneb fork. Update `SignedBlockContents::blobs_cloned` to return blobs for `BlindedBlockAndBlobSidecars`.
* Improve code readability and error handling when converting blinded block into full block.
## Issue Addressed
Fix a deadlock introduced in #4236 which was caught during the v4.4.0 release testing cycle (with thanks to @paulhauner and `gdb`).
## Proposed Changes
Avoid re-locking the fork choice read lock when querying a state by root in the HTTP API. This avoids a deadlock due to the lock already being held.
## Additional Info
The [RwLock docs](https://docs.rs/lock_api/latest/lock_api/struct.RwLock.html#method.read) explicitly advise against re-locking:
> Note that attempts to recursively acquire a read lock on a RwLock when the current thread already holds one may result in a deadlock.
## Issue Addressed
Closes#4473 (take 3)
## Proposed Changes
- Send a 202 status code by default for duplicate blocks, instead of 400. This conveys to the caller that the block was published, but makes no guarantees about its validity. Block relays can count this as a success or a failure as they wish.
- For users wanting finer-grained control over which status is returned for duplicates, a flag `--http-duplicate-block-status` can be used to adjust the behaviour. A 400 status can be supplied to restore the old (spec-compliant) behaviour, or a 200 status can be used to silence VCs that warn loudly for non-200 codes (e.g. Lighthouse prior to v4.4.0).
- Update the Lighthouse VC to gracefully handle success codes other than 200. The info message isn't the nicest thing to read, but it covers all bases and isn't a nasty `ERRO`/`CRIT` that will wake anyone up.
## Additional Info
I'm planning to raise a PR to `beacon-APIs` to specify that clients may return 202 for duplicate blocks. Really it would be nice to use some 2xx code that _isn't_ the same as the code for "published but invalid". I think unfortunately there aren't any suitable codes, and maybe the best fit is `409 CONFLICT`. Given that we need to fix this promptly for our release, I think using the 202 code temporarily with configuration strikes a nice compromise.
## Issue Addressed
Fixes a bug in the handling of `--beacon-process-max-workers` which caused it to have no effect.
## Proposed Changes
For this PR I channeled @ethDreamer and saw deep into the faulty CLI config -- this bug is almost identical to the one Mark found and fixed in #4622.

Since `tolerant_current_epoch` is expected to be either `current_epoch` or `current_epoch+1`, we can eliminate a case here.
And added a comment about `compute_historic_attester_duties` , since `RelativeEpoch::from_epoch` will only allow `request_epoch == current_epoch-1` when `request_epoch < current_epoch`.
## Issue Addressed
Closes#4245
## Proposed Changes
- If an SSE channel fills up, send a comment instead of terminating the stream.
- Add a CLI flag for scaling up the SSE buffer: `--http-sse-capacity-multiplier N`.
## Additional Info
~~Blocked on #4462. I haven't rebased on that PR yet for initial testing, because it still needs some more work to handle long-running HTTP threads.~~
- [x] Add CLI flag tests.
## Issue Addressed
Closes#3404 (mostly)
## Proposed Changes
- Remove all uses of Warp's `and_then` (which backtracks) in favour of `then` (which doesn't).
- Bump the priority of the `POST` method for `v2/blocks` to `P0`. Publishing a block needs to happen quickly.
- Run the new SSZ POST endpoints on the beacon processor. I think this was missed in between merging #4462 and #4504/#4479.
- Fix a minor issue in the validator registrations endpoint whereby an error from spawning the task on the beacon processor would be dropped.
## Additional Info
I've tested this manually and can confirm that we no longer get the dreaded `Unsupported endpoint version` errors for queries like:
```
$ curl -X POST -H "Content-Type: application/json" --data @block.json "http://localhost:5052/eth/v2/beacon/blocks" | jq
{
"code": 400,
"message": "BAD_REQUEST: WeakSubjectivityConflict",
"stacktraces": []
}
```
```
$ curl -X POST -H "Content-Type: application/octet-stream" --data @block.json "http://localhost:5052/eth/v2/beacon/blocks" | jq
{
"code": 400,
"message": "BAD_REQUEST: invalid SSZ: OffsetOutOfBounds(572530811)",
"stacktraces": []
}
```
```
$ curl "http://localhost:5052/eth/v2/validator/blocks/7067595"
{"code":400,"message":"BAD_REQUEST: invalid query: Invalid query string","stacktraces":[]}
```
However, I can still trigger it by leaving off the `Content-Type`. We can re-test this aspect with #4575.
## Issue Addressed
NA
## Proposed Changes
Rather than spawning new tasks on the tokio executor to process each HTTP API request, send the tasks to the `BeaconProcessor`. This achieves:
1. Places a bound on how many concurrent requests are being served (i.e., how many we are actually trying to compute at one time).
1. Places a bound on how many requests can be awaiting a response at one time (i.e., starts dropping requests when we have too many queued).
1. Allows the BN prioritise HTTP requests with respect to messages coming from the P2P network (i.e., proiritise importing gossip blocks rather than serving API requests).
Presently there are two levels of priorities:
- `Priority::P0`
- The beacon processor will prioritise these above everything other than importing new blocks.
- Roughly all validator-sensitive endpoints.
- `Priority::P1`
- The beacon processor will prioritise practically all other P2P messages over these, except for historical backfill things.
- Everything that's not `Priority::P0`
The `--http-enable-beacon-processor false` flag can be supplied to revert back to the old behaviour of spawning new `tokio` tasks for each request:
```
--http-enable-beacon-processor <BOOLEAN>
The beacon processor is a scheduler which provides quality-of-service and DoS protection. When set to
"true", HTTP API requests will queued and scheduled alongside other tasks. When set to "false", HTTP API
responses will be executed immediately. [default: true]
```
## New CLI Flags
I added some other new CLI flags:
```
--beacon-processor-aggregate-batch-size <INTEGER>
Specifies the number of gossip aggregate attestations in a signature verification batch. Higher values may
reduce CPU usage in a healthy network while lower values may increase CPU usage in an unhealthy or hostile
network. [default: 64]
--beacon-processor-attestation-batch-size <INTEGER>
Specifies the number of gossip attestations in a signature verification batch. Higher values may reduce CPU
usage in a healthy network whilst lower values may increase CPU usage in an unhealthy or hostile network.
[default: 64]
--beacon-processor-max-workers <INTEGER>
Specifies the maximum concurrent tasks for the task scheduler. Increasing this value may increase resource
consumption. Reducing the value may result in decreased resource usage and diminished performance. The
default value is the number of logical CPU cores on the host.
--beacon-processor-reprocess-queue-len <INTEGER>
Specifies the length of the queue for messages requiring delayed processing. Higher values may prevent
messages from being dropped while lower values may help protect the node from becoming overwhelmed.
[default: 12288]
```
I needed to add the max-workers flag since the "simulator" flavor tests started failing with HTTP timeouts on the test assertions. I believe they were failing because the Github runners only have 2 cores and there just weren't enough workers available to process our requests in time. I added the other flags since they seem fun to fiddle with.
## Additional Info
I bumped the timeouts on the "simulator" flavor test from 4s to 8s. The prioritisation of consensus messages seems to be causing slower responses, I guess this is what we signed up for 🤷
The `validator/register` validator has some special handling because the relays have a bad habit of timing out on these calls. It seems like a waste of a `BeaconProcessor` worker to just wait for the builder API HTTP response, so we spawn a new `tokio` task to wait for a builder response.
I've added an optimisation for the `GET beacon/states/{state_id}/validators/{validator_id}` endpoint in [efbabe3](efbabe3252). That's the endpoint the VC uses to resolve pubkeys to validator indices, and it's the endpoint that was causing us grief. Perhaps I should move that into a new PR, not sure.
## Issue Addressed
Addresses [#4401](https://github.com/sigp/lighthouse/issues/4401)
## Proposed Changes
Shift some constants into ```ChainSpec``` and remove the constant values from code space.
## Additional Info
I mostly used ```MainnetEthSpec::default_spec()``` for getting ```ChainSpec```. I wonder Did I make a mistake about that.

## Issue Addressed
Upgrade libp2p to v0.52
## Proposed Changes
- **Workflows**: remove installation of `protoc`
- **Book**: remove installation of `protoc`
- **`Dockerfile`s and `cross`**: remove custom base `Dockerfile` for cross since it's no longer needed. Remove `protoc` from remaining `Dockerfiles`s
- **Upgrade `discv5` to `v0.3.1`:** we have some cool stuff in there: no longer needs `protoc` and faster ip updates on cold start
- **Upgrade `prometheus` to `0.21.0`**, now it no longer needs encoding checks
- **things that look like refactors:** bunch of api types were renamed and need to be accessed in a different (clearer) way
- **Lighthouse network**
- connection limits is now a behaviour
- banned peers no longer exist on the swarm level, but at the behaviour level
- `connection_event_buffer_size` now is handled per connection with a buffer size of 4
- `mplex` is deprecated and was removed
- rpc handler now logs the peer to which it belongs
## Additional Info
Tried to keep as much behaviour unchanged as possible. However, there is a great deal of improvements we can do _after_ this upgrade:
- Smart connection limits: Connection limits have been checked only based on numbers, we can now use information about the incoming peer to decide if we want it
- More powerful peer management: Dial attempts from other behaviours can be rejected early
- Incoming connections can be rejected early
- Banning can be returned exclusively to the peer management: We should not get connections to banned peers anymore making use of this
- TCP Nat updates: We might be able to take advantage of confirmed external addresses to check out tcp ports/ips
