## Issue Addressed
The latest version of Rust has new clippy rules & the codebase isn't up to date with them.
## Proposed Changes
Small formatting changes that clippy tells me are functionally equivalent
## Issue Addressed
N/A
## Proposed Changes
Add unit tests for the various CLI flags associated with the beacon node and validator client. These changes require the addition of two new flags: `dump-config` and `immediate-shutdown`.
## Additional Info
Both `dump-config` and `immediate-shutdown` are marked as hidden since they should only be used in testing and other advanced use cases.
**Note:** This requires changing `main.rs` so that the flags can adjust the program behavior as necessary.

## Issue Addressed
#2276
## Proposed Changes
Add the `SensitiveUrl` struct which wraps `Url` and implements custom `Display` and `Debug` traits to redact user secrets from being logged in eth1 endpoints, beacon node endpoints and metrics.
## Additional Info
This also includes a small rewrite of the eth1 crate to make requests using `Url` instead of `&str`.
Some error messages have also been changed to remove `Url` data.

## Proposed Changes
Adds support for downloading the deposit contract from a different location
by setting the environement variables `LIGHTHOUSE_DEPOSIT_CONTRACT_SPEC_URL`
and `LIGHTHOUSE_DEPOSIT_CONTRACT_TESTNET_URL`.
It also adds support to fetch the content from a local file:// URL.
This allows pre fetching to build in an environment without network access.
## Additional Info
Being able to build without network access is required to package the application for https://nixos.org/. But I imagine it might be useful for other distributions too.
## Issue Addressed
N/A
## Proposed Changes
Adds a `no-wait` flag to the validator exit command which exits right after publishing the voluntary exit to the beacon chain. It does not wait for confirmation that the exit has been included in the beacon chain. By default, the flag is false.

## Issue Addressed
NA
## Proposed Changes
Bump versions.
## Additional Info
This is a minor release (not patch) due to the very slight change introduced by #2291.
## Proposed Changes
Use two instances of max cover when packing attestations into blocks: one for the previous epoch, and one for the current epoch. This reduces the amount of computation done by roughly half due to the `O(n^2)` running time of max cover (`2 * (n/2)^2 = n^2/2`). This should help alleviate some load on block proposal, particularly on Prater.
## Issue Addressed
NA
## Proposed Changes
- Adds a specific log and metric for when a block is enshrined as head with a delay that will caused bad attestations
- We *technically* already expose this information, but it's a little tricky to determine during debugging. This makes it nice and explicit.
- Fixes a minor reporting bug with the validator monitor where it was expecting agg. attestations too early (at half-slot rather than two-thirds-slot).
## Additional Info

## Proposed Changes
- Ensure that the [target consistency check](b356f52c5c) is always performed on aggregates.
- Add a regression test.

This is a small PR that cleans up compiler warnings.
The most controversial change is removing the `data_dir` field from the `BeaconChainBuilder`.
It was removed because it was never read.

Which issue # does this PR address?
## Proposed Changes
Avoids cloning the `BeaconState` each time Prometheus scrapes our metrics (generally every 5s 😱).
I think the original motivation behind this was *"don't hold the lock on the head whilst we do computation on it"*, however I think is flawed since our computation here is so small that it'll be quicker than the clone.
The primary motivation here is to maintain a small memory footprint by holding less in memory (i.e., the cloned `BeaconState`) and to avoid the fragmentation-creep that occurs when cloning the big contiguous slabs of memory in the `BeaconState`.
I also collapsed the active/slashed/withdrawn counters into a single loop to increase efficiency.

I noticed the following error on one of our nodes:
```
Mar 18 00:03:35 ip-xxxx lighthouse-bn[333503]: Mar 18 00:03:35.103 ERRO Unable to validate aggregate error: ObservedAttestersError(EpochTooLow { epoch: Epoch(23961), lowest_permissible_epoch: Epoch(23962) }), peer_id: 16Uiu2HAm5GL5KzPLhvfg9MBBFSpBqTVGRFSiTg285oezzWcZzwEv
```
The slot during this log was 766,815 (the last slot of the epoch). I believe this is due to an off-by-one error in `observed_attesters` where we were failing to provide enough capacity to store observations from the previous, current and next epochs. See code comments for further reasoning.

## Proposed Changes
Whilst hacking on something I noticed that the default implementation of `FixedVector` can violate the length constraint!
E.g., `let v: FixedVector<u8; U4> = <_>::default()` would create a fixed vector with length 0, even though it promises to *always* have length 4! This causes SSZ deserialization to fail and probably other things too.
This isn't a security risk as it can't be triggered externally, however it's a foot gun for LH devs.

## Issue Addressed

## Proposed Changes
- Refactor the attester/proposer duties endpoints in the BN
- Performance improvements
- Fixes some potential inconsistencies with the dependent root fields.
- Removes `http_api::beacon_proposer_cache` and just uses the one on the `BeaconChain` instead.
- Move the code for the proposer/attester duties endpoints into separate files, for readability.
- Refactor the `DutiesService` in the VC
- Required to reduce the delay on broadcasting new blocks.
- Gets rid of the `ValidatorDuty` shim struct that came about when we adopted the standard API.
- Separate block/attestation duty tasks so that they don't block each other when one is slow.
- In the VC, use `PublicKeyBytes` to represent validators instead of `PublicKey`. `PublicKey` is a legit crypto object whilst `PublicKeyBytes` is just a byte-array, it's much faster to clone/hash `PublicKeyBytes` and this change has had a significant impact on runtimes.
- Unfortunately this has created lots of dust changes.
- In the BN, store `PublicKeyBytes` in the `beacon_proposer_cache` and allow access to them. The HTTP API always sends `PublicKeyBytes` over the wire and the conversion from `PublicKey` -> `PublickeyBytes` is non-trivial, especially when queries have 100s/1000s of validators (like Pyrmont).
- Add the `state_processing::state_advance` mod which dedups a lot of the "apply `n` skip slots to the state" code.
- This also fixes a bug with some functions which were failing to include a state root as per [this comment](072695284f/consensus/state_processing/src/state_advance.rs (L69-L74)). I couldn't find any instance of this bug that resulted in anything more severe than keying a shuffling cache by the wrong block root.
- Swap the VC block service to use `mpsc` from `tokio` instead of `futures`. This is consistent with the rest of the code base.
~~This PR *reduces* the size of the codebase 🎉~~ It *used* to reduce the size of the code base before I added more comments.
## Observations on Prymont
- Proposer duties times down from peaks of 450ms to consistent <1ms.
- Current epoch attester duties times down from >1s peaks to a consistent 20-30ms.
- Block production down from +600ms to 100-200ms.
## Additional Info
- ~~Blocked on #2241~~
- ~~Blocked on #2234~~
## TODO
- [x] ~~Refactor this into some smaller PRs?~~ Leaving this as-is for now.
- [x] Address `per_slot_processing` roots.
- [x] Investigate slow next epoch times. Not getting added to cache on block processing?
- [x] Consider [this](072695284f/beacon_node/store/src/hot_cold_store.rs (L811-L812)) in the scenario of replacing the state roots

```
The reason for this is that the condition was backwards, so that whole block of code was unreachable.
Looking at the attestations for the block included in the block after, we can see that lots of validators missed it. Some of them may be Lighthouse v1.1.1-v1.2.0-rc.0, but it's probable that they would have missed even with the proposer cache primed, given how late the block 708544 arrived (the cache miss occurred 3.787s after the slot start): https://beaconcha.in/block/708545#attestations
This is a small PR which prevents unwanted bootnodes from being added to the DHT and being dialed when the `--disable-discovery` flag is set.
The main reason one would want to disable discovery is to connect to a fix set of peers. Currently, regardless of what the user does, Lighthouse will populate its DHT with previously known peers and also fill it with the spec's bootnodes. It will then dial the bootnodes that are capable of being dialed. This prevents testing with a fixed peer list.
This PR prevents these excess nodes from being added and dialed if the user has set `--disable-discovery`.
## Issue Addressed
NA
## Proposed Changes
- Use the pre-states from #2174 during block production.
- Running this on Pyrmont shows block production times dropping from ~550ms to ~150ms.
- Create `crit` and `warn` logs when a block is published to the API later than we expect.
- On mainnet we are issuing a warn if the block is published more than 1s later than the slot start and a crit for more than 3s.
- Rename some methods on the `SnapshotCache` for clarity.
- Add the ability to pass the state root to `BeaconChain::produce_block_on_state` to avoid computing a state root. This is a very common LH optimization.
- Add a metric that tracks how late we broadcast blocks received from the HTTP API. This is *technically* a duplicate of a `ValidatorMonitor` log, but I wanted to have it for the case where we aren't monitoring validators too.
## Issue Addressed
Closes#1787
## Proposed Changes
* Abstract the `ValidatorPubkeyCache` over a "backing" which is either a file (legacy), or the database.
* Implement a migration from schema v2 to schema v3, whereby the contents of the cache file are copied to the DB, and then the file is deleted. The next release to include this change must be a minor version bump, and we will need to warn users of the inability to downgrade (this is our first DB schema change since mainnet genesis).
* Move the schema migration code from the `store` crate into the `beacon_chain` crate so that it can access the datadir and the `ValidatorPubkeyCache`, etc. It gets injected back into the `store` via a closure (similar to what we do in fork choice).
## Issue Addressed

## Issue Addressed
Resolves#1944
## Proposed Changes
Adds a "graffiti" key to the `validator_definitions.yml`. Setting the key will override anything passed through the validator `--graffiti` flag.
Returns an error if the value for the graffiti key is > 32 bytes instead of silently truncating.
## Issue Addressed
NA
## Proposed Changes
I was doing some testing and noticed that this error could be a bit nicer. It helps users understand that they need to create a wallet before a validator.

## Issue Addressed
Closes#1621
## Proposed Changes
Use the `disallowed_method` lint to ban uses of `Iterator::{sum,product}` from `types` and `state_processing`.
## Additional Info
The lint is turned off in the tree hash caching code, as it is performance sensitive and overflowy arithmetic is already allowed there.
