379664a648 Improve compilation error on 32-bit (#2424)
## Issue Addressed

Closes #1661

## Proposed Changes

Add a dummy package called `target_check` which gets compiled early in the build and fails if the target is 32-bit

## Additional Info

You can test the efficacy of this check with:

```
cross build --release --manifest-path lighthouse/Cargo.toml --target i686-unknown-linux-gnu
```

In which case this compilation error is shown:

```
error: Lighthouse requires a 64-bit CPU and operating system
  --> common/target_check/src/lib.rs:8:1
   |
8  | / assert_cfg!(
9  | |     target_pointer_width = "64",
10 | |     "Lighthouse requires a 64-bit CPU and operating system",

6583ce325b Minify slashing protection interchange data (#2380)
## Issue Addressed

Closes #2354

## Proposed Changes

Add a `minify` method to `slashing_protection::Interchange` that keeps only the maximum-epoch attestation and maximum-slot block for each validator. Specifically, `minify` constructs "synthetic" attestations (with no `signing_root`) containing the maximum source epoch _and_ the maximum target epoch from the input. This is equivalent to the `minify_synth` algorithm that I've formally verified in this repository:

3dc1eb5eb6 Ignore inactive validators in validator monitor (#2396)
## Proposed Changes

A user on Discord (`@ChewsMacRibs`) reported that the validator monitor was logging `WARN Attested to an incorrect head` for their validator while it was awaiting activation.

This PR modifies the monitor so that it ignores inactive validators, by the logic that they are either awaiting activation, or have already exited. Either way, there's no way for an inactive validator to have their attestations included on chain, so no need for the monitor to report on them.

## Additional Info

To reproduce the bug requires registering validator keys manually with `--validator-monitor-pubkeys`. I don't think the bug will present itself with `--validator-monitor-auto`.

98ab00cc52 Handle Geth pre-EIP-155 block sync error condition (#2304)
## Issue Addressed

#2293 

## Proposed Changes

 - Modify the handler for the `eth_chainId` RPC (i.e., `get_chain_id`) to explicitly match against the Geth error string returned for pre-EIP-155 synced Geth nodes
 - ~~Add a new helper function, `rpc_error_msg`, to aid in the above point~~
 - Refactor `response_result` into `response_result_or_error` and patch reliant RPC handlers accordingly (thanks to @pawanjay176)

## Additional Info

Geth, as of Pangaea Expanse (v1.10.0), returns an explicit error when it is not synced past the EIP-155 block (2675000). Previously, Geth simply returned a chain ID of 0 (which was obviously much easier to handle on Lighthouse's part).

b383836418 Modify Malloc Tuning (#2398)
## Issue Addressed

NA

## Proposed Changes

I've noticed some of the SigP Prater nodes struggling on v1.4.0-rc.0. I suspect this is due to the changes in #2296. Specifically, the trade-off which lowered the memory footprint whilst increasing runtime on some functions.

Presently, this PR is documenting my testing on Prater.

4a6f2fac81 Only perform malloc tuning for beacon node (#2397)
## Issue Addressed

NA

## Proposed Changes

Only run `configure_memory_alllocator` for the BN process.

I noticed that VC memory usage increases significantly with the new malloc tuning parameters. This was also raised by a user on [r/ethstaker](https://www.reddit.com/r/ethstaker/comments/nr8998/lighthouse_prerelease_v140rc0/h0fnt9l?utm_source=share&utm_medium=web2x&context=3).

There wasn't any issue with memory usage by the VC before we implemented #2296, so I think we were a bit overzealous when we allowed these changes to affect it. This PR allows things that weren't broken to remain unfixed.

93100f221f Make less logs for attn with unknown head (#2395)
## Issue Addressed

NA

## Proposed Changes

I am starting to see a lot of slog-async overflows (i.e., too many logs) on Prater whenever we see attestations for an unknown block. Since these logs are identical (except for peer id) and we expose volume/count of these errors via `metrics::GOSSIP_ATTESTATION_ERRORS_PER_TYPE`, I took the following actions to remove them from `DEBUG` logs:

- Push the "Attestation for unknown block" log to trace.
- Add a debug log in `search_for_block`. In effect, this should serve as a de-duped version of the previous, downgraded log.

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

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.

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.

**Note:** This requires changing `main.rs` so that the flags can adjust the program behavior as necessary.

4cc613d644 Add SensitiveUrl to redact user secrets from endpoints (#2326)
## 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.

c646d2f7a3 Allow specifying alternative url for deposit_contract (#2295)
## Issue Addressed

None

## 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.

2992ca66cd Add a no-wait flag for voluntary exits (#2292)
## 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.

3b901dc5ec Pack attestations into blocks in parallel (#2307)
## 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.

c1203f5e52 Add specific log and metric for delayed blocks (#2308)
## 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).

aaa14073ff Clean up warnings (#2240)
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.

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.
