## Proposed Changes
This PR extends #3018 to address my review comments there and add automated integration tests with Geth (and other implementations, in the future).
I've also de-duplicated the "unused port" logic by creating an `common/unused_port` crate.
## Additional Info
I'm not sure if we want to merge this PR, or update #3018 and merge that. I don't mind, I'm primarily opening this PR to make sure CI works.

## Issue Addressed
Closes#3014
## Proposed Changes
- Rename `receipt_root` to `receipts_root`
- Rename `execute_payload` to `notify_new_payload`
- This is slightly weird since we modify everything except the actual HTTP call to the engine API. That change is expected to be implemented in #2985 (cc @ethDreamer)
- Enable "random" tests for Bellatrix.
## Notes
This will break *partially* compatibility with Kintusgi testnets in order to gain compatibility with [Kiln](https://hackmd.io/@n0ble/kiln-spec) testnets. I think it will only break the BN APIs due to the `receipts_root` change, however it might have some other effects too.

## Issue Addressed
#2883
## Proposed Changes
* Added `suggested-fee-recipient` & `suggested-fee-recipient-file` flags to validator client (similar to graffiti / graffiti-file implementation).
* Added proposer preparation service to VC, which sends the fee-recipient of all known validators to the BN via [/eth/v1/validator/prepare_beacon_proposer](https://github.com/ethereum/beacon-APIs/pull/178) api once per slot
* Added [/eth/v1/validator/prepare_beacon_proposer](https://github.com/ethereum/beacon-APIs/pull/178) api endpoint and preparation data caching
* Added cleanup routine to remove cached proposer preparations when not updated for 2 epochs
## Additional Info
Changed the Implementation following the discussion in #2883.

## Issue Addressed
Implements the standard key manager API from https://ethereum.github.io/keymanager-APIs/, formerly https://github.com/ethereum/beacon-APIs/pull/151
Related to https://github.com/sigp/lighthouse/issues/2557
## Proposed Changes
- [x] Add all of the new endpoints from the standard API: GET, POST and DELETE.
- [x] Add a `validators.enabled` column to the slashing protection database to support atomic disable + export.
- [x] Add tests for all the common sequential accesses of the API
- [x] Add tests for interactions with remote signer validators
- [x] Add end-to-end tests for migration of validators from one VC to another
- [x] Implement the authentication scheme from the standard (token bearer auth)
## Additional Info
The `enabled` column in the validators SQL database is necessary to prevent a race condition when exporting slashing protection data. Without the slashing protection database having a way of knowing that a key has been disabled, a concurrent request to sign a message could insert a new record into the database. The `delete_concurrent_with_signing` test exercises this code path, and was indeed failing before the `enabled` column was added.
The validator client authentication has been modified from basic auth to bearer auth, with basic auth preserved for backwards compatibility.
## Proposed Changes
Add a new hardcoded spec for the Gnosis Beacon Chain.
Ideally, official Lighthouse executables will be able to connect to the gnosis beacon chain from now on, using `--network gnosis` CLI option.
## Issue Addressed
N/A
## Proposed Changes
Add a HTTP API which can be used to compute the attestation performances of a validator (or all validators) over a discrete range of epochs.
Performances can be computed for a single validator, or for the global validator set.
## Usage
### Request
The API can be used as follows:
```
curl "http://localhost:5052/lighthouse/analysis/attestation_performance/{validator_index}?start_epoch=57730&end_epoch=57732"
```
Alternatively, to compute performances for the global validator set:
```
curl "http://localhost:5052/lighthouse/analysis/attestation_performance/global?start_epoch=57730&end_epoch=57732"
```
### Response
The response is JSON formatted as follows:
```
[
{
"index": 72,
"epochs": {
"57730": {
"active": true,
"head": false,
"target": false,
"source": false
},
"57731": {
"active": true,
"head": true,
"target": true,
"source": true,
"delay": 1
},
"57732": {
"active": true,
"head": true,
"target": true,
"source": true,
"delay": 1
},
}
}
]
```
> Note that the `"epochs"` are not guaranteed to be in ascending order.
## Additional Info
- This API is intended to be used in our upcoming validator analysis tooling (#2873) and will likely not be very useful for regular users. Some advanced users or block explorers may find this API useful however.
- The request range is limited to 100 epochs (since the range is inclusive and it also computes the `end_epoch` it's actually 101 epochs) to prevent Lighthouse using exceptionally large amounts of memory.
## Issue Addressed

## Proposed Changes
- Bump Lighthouse version to v2.1.1
- Update `thread_local` from v1.1.3 to v1.1.4 to address https://rustsec.org/advisories/RUSTSEC-2022-0006
## Additional Info

## Proposed Changes
This PR establishes compatibility between Lighthouse's VC and Nimbus's BN.
Lighthouse was previously `POST`ing unquoted lists of validator indices to the attester and sync duties endpoints which were (correctly) not accepted by Nimbus. These lists had slipped through the cracks because they didn't have an explicit wrapper type to add `serde` annotations to. I've added the `ValidatorIndexDataRef` newtype in order to implement the modified serialisation behaviour.
## Testing
Combined with https://github.com/sigp/lighthouse/pull/2940, I've confirmed that this PR allows my Lighthouse VC on Prater to validate with the public Nimbus BN listed here: https://github.com/status-im/nimbus-eth2#quickly-test-your-tooling-against-nimbus. I haven't had a block proposal yet, but attestations and sync committee messages are working.
## Additional Info
This may also provide compatibility with Prysm BNs but I haven't had a chance to test that yet.
## Issues Addressed
Closes#2739Closes#2812
## Proposed Changes
Support the deserialization of query strings containing duplicate keys into their corresponding types.
As `warp` does not support this feature natively (as discussed in #2739), it relies on the external library [`serde_array_query`](https://github.com/sigp/serde_array_query) (written by @michaelsproul)
This is backwards compatible meaning that both of the following requests will produce the same output:
```
curl "http://localhost:5052/eth/v1/events?topics=head,block"
```
```
curl "http://localhost:5052/eth/v1/events?topics=head&topics=block"
```
## Additional Info
Certain error messages have changed slightly. This only affects endpoints which accept multiple values.
For example:
```
{"code":400,"message":"BAD_REQUEST: invalid query: Invalid query string","stacktraces":[]}
```
is now
```
{"code":400,"message":"BAD_REQUEST: unable to parse query","stacktraces":[]}
```
The serve order of the endpoints `get_beacon_state_validators` and `get_beacon_state_validators_id` have flipped:
```rust
.or(get_beacon_state_validators_id.boxed())
.or(get_beacon_state_validators.boxed())
```
This is to ensure proper error messages when filter fallback occurs due to the use of the `and_then` filter.
## Future Work
- Cleanup / remove filter fallback behaviour by substituting `and_then` with `then` where appropriate.
- Add regression tests for HTTP API error messages.
## Credits
- @mooori for doing the ground work of investigating possible solutions within the existing Rust ecosystem.
- @michaelsproul for writing [`serde_array_query`](https://github.com/sigp/serde_array_query) and for helping debug the behaviour of the `warp` filter fallback leading to incorrect error messages.
## Proposed Changes
Change the canonical fork name for the merge to Bellatrix. Keep other merge naming the same to avoid churn.
I've also fixed and enabled the `fork` and `transition` tests for Bellatrix, and the v1.1.7 fork choice tests.
Additionally, the `BellatrixPreset` has been added with tests. It gets served via the `/config/spec` API endpoint along with the other presets.
## Issue Addressed
NA
## Proposed Changes
We have observed occasions were under-resourced nodes will receive messages that were valid *at the time*, but later become invalidated due to long waits for a `BeaconProcessor` worker.
In this PR, we will check to see if the message was valid *at the time of receipt*. If it was initially valid but invalid now, we just ignore the message without penalizing the peer.
## Additional Info
NA
## Proposed Changes
Add `mallinfo2` behind a feature flag so that we can get accurate memory metrics during debugging. It can be enabled when building Lighthouse like so (so long as the platform supports it):
```
cargo install --path lighthouse --features "malloc_utils/mallinfo2"
```
## Issue Addressed
Resolves: https://github.com/sigp/lighthouse/issues/2741
Includes: https://github.com/sigp/lighthouse/pull/2853 so that we can get ssz static tests passing here on v1.1.6. If we want to merge that first, we can make this diff slightly smaller
## Proposed Changes
- Changes the `justified_epoch` and `finalized_epoch` in the `ProtoArrayNode` each to an `Option<Checkpoint>`. The `Option` is necessary only for the migration, so not ideal. But does allow us to add a default logic to `None` on these fields during the database migration.
- Adds a database migration from a legacy fork choice struct to the new one, search for all necessary block roots in fork choice by iterating through blocks in the db.
- updates related to https://github.com/ethereum/consensus-specs/pull/2727
- We will have to update the persisted forkchoice to make sure the justified checkpoint stored is correct according to the updated fork choice logic. This boils down to setting the forkchoice store's justified checkpoint to the justified checkpoint of the block that advanced the finalized checkpoint to the current one.
- AFAICT there's no migration steps necessary for the update to allow applying attestations from prior blocks, but would appreciate confirmation on that
- I updated the consensus spec tests to v1.1.6 here, but they will fail until we also implement the proposer score boost updates. I confirmed that the previously failing scenario `new_finalized_slot_is_justified_checkpoint_ancestor` will now pass after the boost updates, but haven't confirmed _all_ tests will pass because I just quickly stubbed out the proposer boost test scenario formatting.
- This PR now also includes proposer boosting https://github.com/ethereum/consensus-specs/pull/2730
## Additional Info
I realized checking justified and finalized roots in fork choice makes it more likely that we trigger this bug: https://github.com/ethereum/consensus-specs/pull/2727
It's possible the combination of justified checkpoint and finalized checkpoint in the forkchoice store is different from in any block in fork choice. So when trying to startup our store's justified checkpoint seems invalid to the rest of fork choice (but it should be valid). When this happens we get an `InvalidBestNode` error and fail to start up. So I'm including that bugfix in this branch.
Todo:
- [x] Fix fork choice tests
- [x] Self review
- [x] Add fix for https://github.com/ethereum/consensus-specs/pull/2727
- [x] Rebase onto Kintusgi
- [x] Fix `num_active_validators` calculation as @michaelsproul pointed out
- [x] Clean up db migrations

## Issue Addressed
Closes#1996
## Proposed Changes
Run a second `Logger` via `sloggers` which logs to a file in the background with:
- separate `debug-level` for background and terminal logging
- the ability to limit log size
- rotation through a customizable number of log files
- an option to compress old log files (`.gz` format)
Add the following new CLI flags:
- `--logfile-debug-level`: The debug level of the log files
- `--logfile-max-size`: The maximum size of each log file
- `--logfile-max-number`: The number of old log files to store
- `--logfile-compress`: Whether to compress old log files
By default background logging uses the `debug` log level and saves logfiles to:
- Beacon Node: `$HOME/.lighthouse/$network/beacon/logs/beacon.log`
- Validator Client: `$HOME/.lighthouse/$network/validators/logs/validator.log`
Or, when using the `--datadir` flag:
`$datadir/beacon/logs/beacon.log` and `$datadir/validators/logs/validator.log`
Once rotated, old logs are stored like so: `beacon.log.1`, `beacon.log.2` etc.
> Note: `beacon.log.1` is always newer than `beacon.log.2`.
## Additional Info
Currently the default value of `--logfile-max-size` is 200 (MB) and `--logfile-max-number` is 5.
This means that the maximum storage space that the logs will take up by default is 1.2GB.
(200MB x 5 from old log files + <200MB the current logfile being written to)
Happy to adjust these default values to whatever people think is appropriate.
It's also worth noting that when logging to a file, we lose our custom `slog` formatting. This means the logfile logs look like this:
```
Oct 27 16:02:50.305 INFO Lighthouse started, version: Lighthouse/v2.0.1-8edd9d4+, module: lighthouse:413

```
While testing some code on Windows, I ran into a failure when using `clippy` via (`make lint`):
```
error: this expression borrows a reference (`&str`) that is immediately dereferenced by the compiler
--> common/filesystem/src/lib.rs:105:43
|
105 | let mut acl = ACL::from_file_path(&path_str, false).map_err(Error::UnableToRetrieveACL)?;
| ^^^^^^^^^ help: change this to: `path_str`

= note: `-D clippy::needless-borrow` implied by `-D warnings`
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#needless_borrow
error: could not compile `filesystem` due to previous error
```
## Proposed Changes
Remove the unnecessary borrow as suggested.
## Additional Info
Since we are only running `clippy` in CI on Ubuntu, I believe we don't have any way (in CI) to detect these Windows specific lint errors (either from new code, or from linting changes from new Rust versions.
This is because code marked as `#[cfg(windows)]` is not checked on `unix` systems and vice versa.
I'm conscious that our CI runs are already taking a long time, and that adding a new Windows `clippy` run would add a non-negligible amount of time to the runs (not sure if this topic has already been discussed), but it something to be aware of.
## Extra Note
I don't think this is the case, but it might be worth someone else running `make lint` on their Windows machines to eliminate the possibility that this is an error specific to my setup.
## Proposed Changes
* Add the `Eth-Consensus-Version` header to the HTTP API for the block and state endpoints. This is part of the v2.1.0 API that was recently released: https://github.com/ethereum/beacon-APIs/pull/170
* Add tests for the above. I refactored the `eth2` crate's helper functions to make this more straight-forward, and introduced some new mixin traits that I think greatly improve readability and flexibility.
* Add a new `map_with_fork!` macro which is useful for decoding a superstruct type without naming all its variants. It is now used for SSZ-decoding `BeaconBlock` and `BeaconState`, and for JSON-decoding `SignedBeaconBlock` in the API.
## Additional Info
The `map_with_fork!` changes will conflict with the Merge changes, but when resolving the conflict the changes from this branch should be preferred (it is no longer necessary to enumerate every fork). The merge fork _will_ need to be added to `map_fork_name_with`.
I have been in the process of debugging libp2p tasks as there is something locking our executor.
This addition adds a metric allowing us to track all tasks within lighthouse allowing us to identify various sections of Lighthouse code that may be taking longer than normal to process.
## Issue Addressed
When compiling with Rust 1.56.0 the compiler generates 3 instances of this warning:
```
warning: trailing semicolon in macro used in expression position
--> common/eth2_network_config/src/lib.rs:181:24
|
181 | })?;
| ^

= note: `#[warn(semicolon_in_expressions_from_macros)]` on by default
= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
= note: for more information, see issue #79813 <https://github.com/rust-lang/rust/issues/79813>
= note: this warning originates in the macro `load_from_file` (in Nightly builds, run with -Z macro-backtrace for more info)
```
This warning is completely harmless, but will be visible to users compiling Lighthouse v2.0.1 (or earlier) with Rust 1.56.0 (to be released October 21st). It is **completely safe** to ignore this warning, it's just a superficial change to Rust's syntax.
## Proposed Changes
This PR removes the semi-colon as recommended, and fixes the new Clippy lints from 1.56.0
## Description
The `eth2_libp2p` crate was originally named and designed to incorporate a simple libp2p integration into lighthouse. Since its origins the crates purpose has expanded dramatically. It now houses a lot more sophistication that is specific to lighthouse and no longer just a libp2p integration.
As of this writing it currently houses the following high-level lighthouse-specific logic:
- Lighthouse's implementation of the eth2 RPC protocol and specific encodings/decodings
- Integration and handling of ENRs with respect to libp2p and eth2
- Lighthouse's discovery logic, its integration with discv5 and logic about searching and handling peers.
- Lighthouse's peer manager - This is a large module handling various aspects of Lighthouse's network, such as peer scoring, handling pings and metadata, connection maintenance and recording, etc.
- Lighthouse's peer database - This is a collection of information stored for each individual peer which is specific to lighthouse. We store connection state, sync state, last seen ips and scores etc. The data stored for each peer is designed for various elements of the lighthouse code base such as syncing and the http api.
- Gossipsub scoring - This stores a collection of gossipsub 1.1 scoring mechanisms that are continuously analyssed and updated based on the ethereum 2 networks and how Lighthouse performs on these networks.
- Lighthouse specific types for managing gossipsub topics, sync status and ENR fields
- Lighthouse's network HTTP API metrics - A collection of metrics for lighthouse network monitoring
- Lighthouse's custom configuration of all networking protocols, RPC, gossipsub, discovery, identify and libp2p.
Therefore it makes sense to rename the crate to be more akin to its current purposes, simply that it manages the majority of Lighthouse's network stack. This PR renames this crate to `lighthouse_network`

## Proposed Changes
- Update versions to `v2.0.1` in anticipation for a release early next week.
- Add `--ignore` to `cargo audit`. See #2727.
## Additional Info
NA
Currently, the beacon node has no ability to serve the HTTP API over TLS.
Adding this functionality would be helpful for certain use cases, such as when you need a validator client to connect to a backup beacon node which is outside your local network, and the use of an SSH tunnel or reverse proxy would be inappropriate.
## Proposed Changes
- Add three new CLI flags to the beacon node
- `--http-enable-tls`: enables TLS
- `--http-tls-cert`: to specify the path to the certificate file
- `--http-tls-key`: to specify the path to the key file
- Update the HTTP API to optionally use `warp`'s [`TlsServer`](https://docs.rs/warp/0.3.1/warp/struct.TlsServer.html) depending on the presence of the `--http-enable-tls` flag
- Update tests and docs
- Use a custom branch for `warp` to ensure proper error handling
## Additional Info
Serving the API over TLS should currently be considered experimental. The reason for this is that it uses code from an [unmerged PR](https://github.com/seanmonstar/warp/pull/717). This commit provides the `try_bind_with_graceful_shutdown` method to `warp`, which is helpful for controlling error flow when the TLS configuration is invalid (cert/key files don't exist, incorrect permissions, etc).
I've implemented the same code in my [branch here](https://github.com/macladson/warp/tree/tls).
Once the code has been reviewed and merged upstream into `warp`, we can remove the dependency on my branch and the feature can be considered more stable.
Currently, the private key file must not be password-protected in order to be read into Lighthouse.
## Issue Addressed
Fix `cargo audit` failures on `unstable`
Closes#2698
## Proposed Changes
The main culprit is `nix`, which is vulnerable for versions below v0.23.0. We can't get by with a straight-forward `cargo update` because `psutil` depends on an old version of `nix` (cf. https://github.com/rust-psutil/rust-psutil/pull/93). Hence I've temporarily forked `psutil` under the `sigp` org, where I've included the update to `nix` v0.23.0.
Additionally, I took the chance to update the `time` dependency to v0.3, which removed a bunch of stale deps including `stdweb` which is no longer maintained. Lighthouse only uses the `time` crate in the notifier to do some pretty printing, and so wasn't affected by any of the breaking changes in v0.3 ([changelog here](https://github.com/time-rs/time/blob/main/CHANGELOG.md#030-2021-07-30)).
## Proposed Changes
While investigating memory usage I noticed that the malloc metrics were going negative once they passed 2GiB. This is because the underlying `mallinfo` function returns a `i32`, and we were casting it straight to an `i64`, preserving the sign.
The long-term fix will be to move to `mallinfo2`, but it's still not yet widely available.
## Issue Addressed
Fix#2585
## Proposed Changes
Provide a canonical version of test_logger that can be used
throughout lighthouse.
## Additional Info
This allows tests to conditionally emit logging data by adding
test_logger as the default logger. And then when executing
`cargo test --features logging/test_logger` log output
will be visible:

## Additional Info

## Issue Addressed
Closes#2528
## Proposed Changes
- Add `BlockTimesCache` to provide block timing information to `BeaconChain`. This allows additional metrics to be calculated for blocks that are set as head too late.
- Thread the `seen_timestamp` of blocks received from RPC responses (except blocks from syncing) through to the sync manager, similar to what is done for blocks from gossip.
## Additional Info
This provides the following additional metrics:
- `BEACON_BLOCK_OBSERVED_SLOT_START_DELAY_TIME`
- The delay between the start of the slot and when the block was first observed.
- `BEACON_BLOCK_IMPORTED_OBSERVED_DELAY_TIME`
- The delay between when the block was first observed and when the block was imported.
- `BEACON_BLOCK_HEAD_IMPORTED_DELAY_TIME`
- The delay between when the block was imported and when the block was set as head.
The metric `BEACON_BLOCK_IMPORTED_SLOT_START_DELAY_TIME` was removed.
A log is produced when a block is set as head too late, e.g.:
```
Aug 27 03:46:39.006 DEBG Delayed head block set_as_head_delay: Some(21.731066ms), imported_delay: Some(119.929934ms), observed_delay: Some(3.864596988s), block_delay: 4.006257988s, slot: 1931331, proposer_index: 24294, block_root: 0x937602c89d3143afa89088a44bdf4b4d0d760dad082abacb229495c048648a9e, service: beacon
