* 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
* changed name
* Fix sidecars
* Added query type and parrameter
* added query struct and function
* added method
* improved filtering method
* added blob_sidecar_list_indexed to block_id
* minor blobqueryindex fix
* function and formatting fix
* minor function and naming fix
* minor changes
* changed name
* Fix sidecars
* update get blobs endpoint name from blobs to blob_sidecars

## Issue Addressed
NA
## Proposed Changes
Implements the `PrettyReqwestError` to wrap a `reqwest::Error` and give nicer `Debug` formatting. It also wraps the `Url` component in a `SensitiveUrl` to avoid leaking sensitive info in logs.
### Before
```
Reqwest(reqwest::Error { kind: Request, url: Url { scheme: "http", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("localhost")), port: Some(9999), path: "/eth/v1/node/version", query: None, fragment: None }, source: hyper::Error(Connect, ConnectError("tcp connect error", Os { code: 61, kind: ConnectionRefused, message: "Connection refused" })) })
```
### After
```
HttpClient(url: http://localhost:9999/, kind: request, detail: error trying to connect: tcp connect error: Connection refused (os error 61))
```
## Additional Info
I've also renamed the `Reqwest` error enum variants to `HttpClient`, to give people a better chance at knowing what's going on. Reqwest is pretty odd and looks like a typo.
I've implemented it in the `eth2` and `execution_layer` crates. This should affect most logs in the VC and EE-related ones in the BN.
I think the last crate that could benefit from the is the `beacon_node/eth1` crate. I haven't updated it in this PR since its error type is not so amenable to it (everything goes into a `String`). I don't have a whole lot of time to jig around with that at the moment and I feel that this PR as it stands is a significant enough improvement to merge on its own. Leaving it as-is is fine for the time being and we can always come back for it later (or implement in-protocol deposits!).
## Issue Addressed
#4386
## Proposed Changes
The original proposal described in the issue adds a new endpoint to support updating validator graffiti, but I realized we already have an endpoint that we use for updating various validator fields in memory and in the validator definitions file, so I think that would be the best place to add this to.
### API endpoint
`PATCH lighthouse/validators/{validator_pubkey}`
This endpoint updates the graffiti in both the [ validator definition file](https://lighthouse-book.sigmaprime.io/graffiti.html#2-setting-the-graffiti-in-the-validator_definitionsyml) and the in memory `InitializedValidators`. In the next block proposal, the new graffiti will be used.
Note that the [`--graffiti-file`](https://lighthouse-book.sigmaprime.io/graffiti.html#1-using-the---graffiti-file-flag-on-the-validator-client) flag has a priority over the validator definitions file, so if the caller attempts to update the graffiti while the `--graffiti-file` flag is present, the endpoint will return an error (Bad request 400).
## Tasks
- [x] Add graffiti update support to `PATCH lighthouse/validators/{validator_pubkey}`
- [x] Return error if user tries to update graffiti while the `--graffiti-flag` is set
- [x] Update Lighthouse book
Checkpointz now supports deposit snapshot but [they only support returning them in JSON](https://github.com/ethpandaops/checkpointz/issues/74) so I've modified lighthouse to request them in JSON by default.
There's also `get_opt` & `get_opt_with_timeout` methods which seem to expect responses in JSON but were not adding `Accept: application/json` to the request headers so I fixed that as well.
Also the beacon API puts quantities in quotes so I fixed that in the snapshot JSON serialization
## Issue Addressed
#3510
## Proposed Changes
- Replace mime with MediaTypeList
- Remove parse_accept fn as MediaTypeList does it built-in
- Get the supported media type of the highest q-factor in a single list iteration without sorting
## Additional Info
I have addressed the suggested changes in previous [PR](https://github.com/sigp/lighthouse/pull/3520#discussion_r959048633)
## Issue Addressed
Closes https://github.com/sigp/lighthouse/issues/4291, part of #3613.
## Proposed Changes
- Implement the `el_offline` field on `/eth/v1/node/syncing`. We set `el_offline=true` if:
- The EL's internal status is `Offline` or `AuthFailed`, _or_
- The most recent call to `newPayload` resulted in an error (more on this in a moment).
- Use the `el_offline` field in the VC to mark nodes with offline ELs as _unsynced_. These nodes will still be used, but only after synced nodes.
- Overhaul the usage of `RequireSynced` so that `::No` is used almost everywhere. The `--allow-unsynced` flag was broken and had the opposite effect to intended, so it has been deprecated.
- Add tests for the EL being offline on the upcheck call, and being offline due to the newPayload check.
## Why track `newPayload` errors?
Tracking the EL's online/offline status is too coarse-grained to be useful in practice, because:
- If the EL is timing out to some calls, it's unlikely to timeout on the `upcheck` call, which is _just_ `eth_syncing`. Every failed call is followed by an upcheck [here](693886b941/beacon_node/execution_layer/src/engines.rs (L372-L380)), which would have the effect of masking the failure and keeping the status _online_.
- The `newPayload` call is the most likely to time out. It's the call in which ELs tend to do most of their work (often 1-2 seconds), with `forkchoiceUpdated` usually returning much faster (<50ms).
- If `newPayload` is failing consistently (e.g. timing out) then this is a good indication that either the node's EL is in trouble, or the network as a whole is. In the first case validator clients _should_ prefer other BNs if they have one available. In the second case, all of their BNs will likely report `el_offline` and they'll just have to proceed with trying to use them.
## Additional Changes
- Add utility method `ForkName::latest` which is quite convenient for test writing, but probably other things too.
- Delete some stale comments from when we used to support multiple execution nodes.
## Issue Addressed
#4233
## Proposed Changes
Remove the `best_justified_checkpoint` from the `PersistedForkChoiceStore` type as it is now unused.
Additionally, remove the `Option`'s wrapping the `justified_checkpoint` and `finalized_checkpoint` fields on `ProtoNode` which were only present to facilitate a previous migration.
Include the necessary code to facilitate the migration to a new DB schema.
## Issue Addressed
#4146
## Proposed Changes
Removes the `ExecutionOptimisticForkVersionedResponse` type and the associated Beacon API endpoint which is now deprecated. Also removes the test associated with the endpoint.
> This is currently a WIP and all features are subject to alteration or removal at any time.
## Overview
The successor to #2873.
Contains the backbone of `beacon.watch` including syncing code, the initial API, and several core database tables.
See `watch/README.md` for more information, requirements and usage.
## Issue Addressed
Addresses #4117
## Proposed Changes

## TODO
- [x] ~~Add submission to BN~~
- removed, see discussion in [keymanager API](https://github.com/ethereum/keymanager-APIs/pull/58)
- [x] ~~Add flag to allow voluntary exit via the API~~
- no longer needed now the VC doesn't submit exit directly
- [x] ~~Additional verification / checks, e.g. if validator on same network as BN~~
- to be done on client side
- [x] ~~Potentially wait for the message to propagate and return some exit information in the response~~
- not required
- [x] Update http tests
- [x] ~~Update lighthouse book~~
- not required if this endpoint makes it to the standard keymanager API

## Issue Addressed
In #4027 I forgot to add the `parent_block_number` to the payload attributes SSE.
## Proposed Changes
Compute the parent block number while computing the pre-payload attributes. Pass it on to the SSE stream.
## Additional Info
Not essential for v3.5.1 as I suspect most builders don't need the `parent_block_root`. I would like to use it for my dummy no-op builder however.
## Issue Addressed
Closes#3896Closes#3998Closes#3700
## Proposed Changes
- Optimise the calculation of withdrawals for payload attributes by avoiding state clones, avoiding unnecessary state advances and reading from the snapshot cache if possible.
- Use the execution layer's payload attributes cache to avoid re-calculating payload attributes. I actually implemented a new LRU cache just for withdrawals but it had the exact same key and most of the same data as the existing payload attributes cache, so I deleted it.
- Add a new SSE event that fires when payloadAttributes are calculated. This is useful for block builders, a la https://github.com/ethereum/beacon-APIs/issues/244.
- Add a new CLI flag `--always-prepare-payload` which forces payload attributes to be sent with every fcU regardless of connected proposers. This is intended for use by builders/relays.
For maximum effect, the flags I've been using to run Lighthouse in "payload builder mode" are:
```
--always-prepare-payload \
--prepare-payload-lookahead 12000 \
--suggested-fee-recipient 0x0000000000000000000000000000000000000000
```
The fee recipient is required so Lighthouse has something to pack in the payload attributes (it can be ignored by the builder). The lookahead causes fcU to be sent at the start of every slot rather than at 8s. As usual, fcU will also be sent after each change of head block. I think this combination is sufficient for builders to build on all viable heads. Often there will be two fcU (and two payload attributes) sent for the same slot: one sent at the start of the slot with the head from `n - 1` as the parent, and one sent after the block arrives with `n` as the parent.
Example usage of the new event stream:
```bash
curl -N "http://localhost:5052/eth/v1/events?topics=payload_attributes"
```
## Additional Info
- [x] Tests added by updating the proposer re-org tests. This has the benefit of testing the proposer re-org code paths with withdrawals too, confirming that the new changes don't interact poorly.
- [ ] Benchmarking with `blockdreamer` on devnet-7 showed promising results but I'm yet to do a comparison to `unstable`.

## Issue Addressed
Cleans up all the remnants of 4844 in capella. This makes sure when 4844 is reviewed there is nothing we are missing because it got included here
## Proposed Changes
drop a bomb on every 4844 thing
## Additional Info
Merge process I did (locally) is as follows:
- squash merge to produce one commit
- in new branch off unstable with the squashed commit create a `git revert HEAD` commit
- merge that new branch onto 4844 with `--strategy ours`
- compare local 4844 to remote 4844 and make sure the diff is empty
- enjoy
