f6280aa663 v1.4.0-rc.0 (#2379)
## Issue Addressed

NA

## Proposed Changes

Bump versions.

## Additional Info

This is not exactly the v1.4.0 release described in [Lighthouse Update #36](https://lighthouse.sigmaprime.io/update-36.html).

Whilst it contains:

- Beta Windows support
- A reduction in Eth1 queries
- A reduction in memory footprint

It does not contain:

- Altair
- Doppelganger Protection
- The remote signer

We have decided to release some features early. This is primarily due to the desire to allow users to benefit from the memory saving improvements as soon as possible.

## TODO

- [x] Wait for #2340, #2356 and #2376 to merge and then rebase on `unstable`. 
- [x] Ensure discovery issues are fixed (see #2388)
- [x] Ensure https://github.com/sigp/lighthouse/pull/2382 is merged/removed.
- [x] Ensure https://github.com/sigp/lighthouse/pull/2383 is merged/removed.
- [x] Ensure https://github.com/sigp/lighthouse/pull/2384 is merged/removed.
- [ ] Double-check eth1 cache is carried between boots

d34f922c1d Add early check for RPC block relevancy (#2289)
## Issue Addressed

NA

## Proposed Changes

When observing `jemallocator` heap profiles and Grafana, it became clear that Lighthouse is spending significant RAM/CPU on processing blocks from the RPC. On investigation, it seems that we are loading the parent of the block *before* we check to see if the block is already known. This is a big waste of resources.

This PR adds an additional `check_block_relevancy` call as the first thing we do when we try to process a `SignedBeaconBlock` via the RPC (or other similar methods). Ultimately, `check_block_relevancy` will be called again later in the block processing flow. It's a very light function and I don't think trying to optimize it out is worth the risk of a bad block slipping through. 

Also adds a `New RPC block received` info log when we process a new RPC block. This seems like interesting and infrequent info.

bf4e02e2cc Return a specific error for frozen attn states (#2384)
## Issue Addressed

NA

## Proposed Changes

Return a very specific error when at attestation reads shuffling from a frozen `BeaconState`. Previously, this was returning `MissingBeaconState` which indicates a much more serious issue.

## Additional Info

Since `get_inconsistent_state_for_attestation_verification_only` is only called once in `BeaconChain::with_committee_cache`, it is quite easy to reason about the impact of this change.

ba9c4c5eea Return more detail in Eth1 HTTP errors (#2383)
## Issue Addressed

NA

## Proposed Changes

Whilst investigating #2372, I [learned](https://github.com/sigp/lighthouse/issues/2372#issuecomment-851725049) that the error message returned from some failed Eth1 requests are always `NotReachable`. This makes debugging quite painful.

This PR adds more detail to these errors. For example:

- Bad infura key: `ERRO Failed to update eth1 cache             error: Failed to update Eth1 service: "All fallback errored: https://mainnet.infura.io/ => EndpointError(RequestFailed(\"Response HTTP status was not 200 OK:  401 Unauthorized.\"))", retry_millis: 60000, service: eth1_rpc`
- Unreachable server: `ERRO Failed to update eth1 cache             error: Failed to update Eth1 service: "All fallback errored: http://127.0.0.1:8545/ => EndpointError(RequestFailed(\"Request failed: reqwest::Error { kind: Request, url: Url { scheme: \\\"http\\\", cannot_be_a_base: false, username: \\\"\\\", password: None, host: Some(Ipv4(127.0.0.1)), port: Some(8545), path: \\\"/\\\", query: None, fragment: None }, source: hyper::Error(Connect, ConnectError(\\\"tcp connect error\\\", Os { code: 111, kind: ConnectionRefused, message: \\\"Connection refused\\\" })) }\"))", retry_millis: 60000, service: eth1_rpc`
- Bad server: `ERRO Failed to update eth1 cache             error: Failed to update Eth1 service: "All fallback errored: http://127.0.0.1:8545/ => EndpointError(RequestFailed(\"Response HTTP status was not 200 OK:  501 Not Implemented.\"))", retry_millis: 60000, service: eth1_rpc`

4c7bb4984c Use the forwards iterator more often (#2376)
## Issue Addressed

NA

## Primary Change

When investigating memory usage, I noticed that retrieving a block from an early slot (e.g., slot 900) would cause a sharp increase in the memory footprint (from 400mb to 800mb+) which seemed to be ever-lasting.

After some investigation, I found that the reverse iteration from the head back to that slot was the likely culprit. To counter this, I've switched the `BeaconChain::block_root_at_slot` to use the forwards iterator, instead of the reverse one.

I also noticed that the networking stack is using `BeaconChain::root_at_slot` to check if a peer is relevant (`check_peer_relevance`). Perhaps the steep, seemingly-random-but-consistent increases in memory usage are caused by the use of this function.

Using the forwards iterator with the HTTP API alleviated the sharp increases in memory usage. It also made the response much faster (before it felt like to took 1-2s, now it feels instant).

## Additional Changes

In the process I also noticed that we have two functions for getting block roots:

- `BeaconChain::block_root_at_slot`: returns `None` for a skip slot.
- `BeaconChain::root_at_slot`: returns the previous root for a skip slot.

I unified these two functions into `block_root_at_slot` and added the `WhenSlotSkipped` enum. Now, the caller must be explicit about the skip-slot behaviour when requesting a root. 

Additionally, I replaced `vec![]` with `Vec::with_capacity` in `store::chunked_vector::range_query`. I stumbled across this whilst debugging and made this modification to see what effect it would have (not much). It seems like a decent change to keep around, but I'm not concerned either way.

Also, `BeaconChain::get_ancestor_block_root` is unused, so I got rid of it 🗑️.

## Additional Info

I haven't also done the same for state roots here. Whilst it's possible and a good idea, it's more work since the fwds iterators are presently block-roots-specific.

Whilst there's a few places a reverse iteration of state roots could be triggered (e.g., attestation production, HTTP API), they're no where near as common as the `check_peer_relevance` call. As such, I think we should get this PR merged first, then come back for the state root iters. I made an issue here https://github.com/sigp/lighthouse/issues/2377.

320a683e72 Minimum Outbound-Only Peers Requirement (#2356)
## Issue Addressed

#2325 

## Proposed Changes

This pull request changes the behavior of the Peer Manager by including a minimum outbound-only peers requirement. The peer manager will continue querying for peers if this outbound-only target number hasn't been met. Additionally, when peers are being removed, an outbound-only peer will not be disconnected if doing so brings us below the minimum. 

## Additional Info

Unit test for heartbeat function tests that disconnection behavior is correct. Continual querying for peers if outbound-only hasn't been met is not directly tested, but indirectly through unit testing of the helper function that counts the number of outbound-only peers.

EDIT: Am concerned about the behavior of ```update_peer_scores```. If we have connected to a peer with a score below the disconnection threshold (-20), then its connection status will remain connected, while its score state will change to disconnected. 

```rust
let previous_state = info.score_state();            
// Update scores            
info.score_update();
Self::handle_score_transitions(                
               previous_state,
                peer_id,
                info, 
               &mut to_ban_peers,
               &mut to_unban_peers,
               &mut self.events,
               &self.log,
);
```

```previous_state``` will be set to Disconnected, and then because ```handle_score_transitions``` only changes connection status for a peer if the state changed, the peer remains connected. Then in the heartbeat code, because we only disconnect healthy peers if we have too many peers, these peers don't get disconnected. I'm not sure realistically how often this scenario would occur, but it might be better to adjust the logic to account for scenarios where the score state implies a connection status different from the current connection status.

0847986936 Reduce outbound requests to eth1 endpoints (#2340)
## Issue Addressed

#2282 

## Proposed Changes

Reduce the outbound requests made to eth1 endpoints by caching the results from `eth_chainId` and `net_version`.
Further reduce the overall request count by increasing `auto_update_interval_millis` from `7_000` (7 seconds) to `60_000` (1 minute). 
This will result in a reduction from ~2000 requests per hour to 360 requests per hour (during normal operation). A reduction of 82%.

## Additional Info

If an endpoint fails, its state is dropped from the cache and the `eth_chainId` and `net_version` calls will be made for that endpoint again during the regular update cycle (once per minute) until it is back online.

ec5cceba50 Correct issue with dialing peers (#2375)
The ordering of adding new peers to the peerdb and deciding when to dial them was not considered in a previous update.

This adds the condition that if a peer is not in the peer-db then it is an acceptable peer to dial.

456b313665 Tune GNU malloc (#2299)
## Issue Addressed

NA

## Proposed Changes

Modify the configuration of [GNU malloc](https://www.gnu.org/software/libc/manual/html_node/The-GNU-Allocator.html) to reduce memory footprint.

- Set `M_ARENA_MAX` to 4.
    - This reduces memory fragmentation at the cost of contention between threads.
- Set `M_MMAP_THRESHOLD` to 2mb
    - This means that any allocation >= 2mb is allocated via an anonymous mmap, instead of on the heap/arena. This reduces memory fragmentation since we don't need to keep growing the heap to find big contiguous slabs of free memory.
- ~~Run `malloc_trim` every 60 seconds.~~
    - ~~This shaves unused memory from the top of the heap, preventing the heap from constantly growing.~~
    - Removed, see: https://github.com/sigp/lighthouse/pull/2299#issuecomment-825322646

*Note: this only provides memory savings on the Linux (glibc) platform.*
    
## Additional Info

I'm going to close #2288 in favor of this for the following reasons:

- I've managed to get the memory footprint *smaller* here than with jemalloc.
- This PR seems to be less of a dramatic change than bringing in the jemalloc dep.
- The changes in this PR are strictly runtime changes, so we can create CLI flags which disable them completely. Since this change is wide-reaching and complex, it's nice to have an easy "escape hatch" if there are undesired consequences.

## TODO

- [x] Allow configuration via CLI flags
- [x] Test on Mac
- [x] Test on RasPi.
- [x] Determine if GNU malloc is present?
    - I'm not quite sure how to detect for glibc.. This issue suggests we can't really: https://github.com/rust-lang/rust/issues/33244
- [x] Make a clear argument regarding the affect of this on CPU utilization.
- [x] Test with higher `M_ARENA_MAX` values.
- [x] Test with longer trim intervals
- [x] Add some stats about memory savings
- [x] Remove `malloc_trim` calls & code

ba55e140ae Enable Compatibility with Windows (#2333)
## Issue Addressed

Windows incompatibility.

## Proposed Changes

On windows, lighthouse needs to default to STDIN as tty doesn't exist. Also Windows uses ACLs for file permissions. So to mirror chmod 600, we will remove every entry in a file's ACL and add only a single SID that is an alias for the file owner.

Beyond that, there were several changes made to different unit tests because windows has slightly different error messages as well as frustrating nuances around killing a process :/

## Additional Info

Tested on my Windows VM and it appears to work, also compiled & tested on Linux with these changes. Permissions look correct on both platforms now. Just waiting for my validator to activate on Prater so I can test running full validator client on windows.

58e52f8f40 Write validator definitions atomically (#2338)
## Issue Addressed

Closes https://github.com/sigp/lighthouse/issues/2159

## Proposed Changes

Rather than trying to write the validator definitions to disk directly, use a temporary file called `.validator_defintions.yml.tmp` and then atomically rename it to `validator_definitions.yml`. This avoids truncating the primary file, which can cause permanent damage when the disk is full.

The same treatment is also applied to the validator key cache, although the situation is less dire if it becomes corrupted because it can just be deleted without the user having to reimport keys or resupply passwords.

## Additional Info

* `File::create` truncates upon opening: https://doc.rust-lang.org/std/fs/struct.File.html#method.create
* `fs::rename` uses `rename` on UNIX and `MoveFileEx` on Windows: https://doc.rust-lang.org/std/fs/fn.rename.html
* UNIX `rename` call is atomic: https://unix.stackexchange.com/questions/322038/is-mv-atomic-on-my-fs
* Windows `MoveFileEx` is _not_ atomic in general, and Windows lacks any clear API for atomic file renames :(
   https://stackoverflow.com/questions/167414/is-an-atomic-file-rename-with-overwrite-possible-on-windows

## Further Work

* Consider whether we want to try a different Windows syscall as part of #2333. The `rust-atomicwrites` crate seems promising, but actually uses the same syscall under the hood presently: https://github.com/untitaker/rust-atomicwrites/issues/27.

## 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.

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.

e7e5878953 Avoid BeaconState clone during metrics scrape (#2298)
## Issue Addressed

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.

03cefd0065 Expand observed attestations capacity (#2266)
## Issue Addressed

NA

## Proposed Changes

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.

Here's a link to the spec: https://github.com/ethereum/eth2.0-specs/blob/v1.0.1/specs/phase0/p2p-interface.md#beacon_aggregate_and_proof

f9d60f5436 VC: accept unknown fields in chain spec (#2277)
## Issue Addressed

Closes #2274

## Proposed Changes

* Modify the `YamlConfig` to collect unknown fields into an `extra_fields` map, instead of failing hard.
* Log a debug message if there are extra fields returned to the VC from one of its BNs.

This restores Lighthouse's compatibility with Teku beacon nodes (and therefore Infura)

9a71a7e486 Fix default implementation on FixedVector (#2264)
## Issue Addressed

NA

## 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.

015ab7d0a7 Optimize validator duties (#2243)
## Issue Addressed

Closes #2052

## 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

6a69b20be1 Validator import password flag (#2228)
## Issue Addressed

#2224

## Proposed Changes

Add a `--password-file` option to the `lighthouse account validator import` command. The flag requires `--reuse-password` and will copy the password over to the `validator_definitions.yml` file. I used #2070 as a guide for validating the password as UTF-8 and stripping newlines.
