## Issue Addressed
The feature flag used to control this feature is `disable_backfill` instead of `disable-backfill`.
kudos to @michaelsproul for discovering this bug!
## 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
#4538
## Proposed Changes
add newtype wrapper around DialError that extracts error messages and logs them in a more readable format
## Additional Info
I was able to test Transport Dial Errors in the situation where a libp2p instance attempts to ping a nonexistent peer. That error message should look something like
`A transport level error has ocurred: Connection refused (os error 61)`
AgeManning mentioned we should try fetching only the most inner error (in situations where theres a nested error). I took a stab at implementing that
For non transport DialErrors, I wrote out the error messages explicitly (as per the docs). Could potentially clean things up here if thats not necessary

## 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.
* remove closure from `check_availability_mayb_import`
* impove logging, add wrapper struct to requested ids
* improve logging
* only log if we're in deneb. Only delay lookup if we're in deneb
* fix bug in missing components check
## Issue Addressed
Addresses #2557
## Proposed Changes
Adds the `lighthouse validator-manager` command, which provides:
- `lighthouse validator-manager create`
- Creates a `validators.json` file and a `deposits.json` (same format as https://github.com/ethereum/staking-deposit-cli)
- `lighthouse validator-manager import`
- Imports validators from a `validators.json` file to the VC via the HTTP API.
- `lighthouse validator-manager move`
- Moves validators from one VC to the other, utilizing only the VC API.
## Additional Info
In 98bcb947c I've reduced some VC `ERRO` and `CRIT` warnings to `WARN` or `DEBG` for the case where a pubkey is missing from the validator store. These were being triggered when we removed a validator but still had it in caches. It seems to me that `UnknownPubkey` will only happen in the case where we've removed a validator, so downgrading the logs is prudent. All the logs are `DEBG` apart from attestations and blocks which are `WARN`. I thought having *some* logging about this condition might help us down the track.
In 856cd7e37d I've made the VC delete the corresponding password file when it's deleting a keystore. This seemed like nice hygiene. Notably, it'll only delete that password file after it scans the validator definitions and finds that no other validator is also using that password file.
## Issue Addressed

## Proposed Changes
We've been seeing a lot of [CI failures](https://github.com/sigp/lighthouse/actions/runs/5781296217/job/15666209142) with errors like this:
```
---- extra_interchange_tests::export_same_key_twice stdout ----
thread 'extra_interchange_tests::export_same_key_twice' panicked at 'called `Result::unwrap()` on an `Err` value: SQLError("Unable to open database: Error(None)")', validator_client/slashing_protection/src/extra_interchange_tests.rs:48:67
```
I'm assuming they're timeouts. I noticed that tests have a 0.1s timeout. Perhaps this just doesn't cut it when our new runners are overloaded.
## Additional Info
NA
**Motivation**
As clarified [on discord](https://discord.com/channels/605577013327167508/605577013331361793/1121246688183603240), sync committee contributions are not delayed if DP is enabled.
**Description**
This PR updates doppelganger note about sync committee contributions. Based on the current docs, a user might assume that DP is not working as expected.
* Low hanging fruits
* Remove unnecessary todo
I think it's fine to not handle this since the calling functions handle the error.
No specific reason imo to handle it in the function as well.
* Rename BlobError to GossipBlobError
I feel this signified better what the error is for. The BlobError was only for failures when gossip
verifying a blob. We cannot get this error when doing rpc validation
* Remove the BlockError::BlobValidation variant
This error was only there to appease gossip verification before publish.
It's unclear how to peer score this error since this cannot actually occur during any
block verification flows.
This commit introuduces an additional error type BlockContentsError to better represent the
Error type
* Add docs for peer scoring (or lack thereof) of AvailabilityCheck errors
* I do not see a non-convoluted way of doing this. Okay to have some redundant code here
* Removing this to catch the failure red handed
* Fix compilation
* Cannot be deleted because some tests assume the trait impl
Also useful to have around for testing in the future imo
* Add some metrics and logs
* Only process `Imported` variant in sync_methods
The only additional thing for other variants that might be useful is logging. We can do that
later if required
* Convert to TryFrom
Not really sure where this would be used, but just did what the comment says.
Could consider just returning the Block variant for a deneb block in the From version
* Unlikely to change now
* This is fine as this is max_rpc_size per rpc chunk (for blobs, it would be 128kb max)
* Log count instead of individual blobs, can delete log later if it becomes too annoying.
* Add block production blob verification timer
* Extend block_straemer test to deneb
* Remove dbg statement
* Fix tests
## 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.
