Use async code when interacting with EL (#3244)
## Overview
This rather extensive PR achieves two primary goals:
1. Uses the finalized/justified checkpoints of fork choice (FC), rather than that of the head state.
2. Refactors fork choice, block production and block processing to `async` functions.
Additionally, it achieves:
- Concurrent forkchoice updates to the EL and cache pruning after a new head is selected.
- Concurrent "block packing" (attestations, etc) and execution payload retrieval during block production.
- Concurrent per-block-processing and execution payload verification during block processing.
- The `Arc`-ification of `SignedBeaconBlock` during block processing (it's never mutated, so why not?):
- I had to do this to deal with sending blocks into spawned tasks.
- Previously we were cloning the beacon block at least 2 times during each block processing, these clones are either removed or turned into cheaper `Arc` clones.
- We were also `Box`-ing and un-`Box`-ing beacon blocks as they moved throughout the networking crate. This is not a big deal, but it's nice to avoid shifting things between the stack and heap.
- Avoids cloning *all the blocks* in *every chain segment* during sync.
- It also has the potential to clean up our code where we need to pass an *owned* block around so we can send it back in the case of an error (I didn't do much of this, my PR is already big enough 😅)
- The `BeaconChain::HeadSafetyStatus` struct was removed. It was an old relic from prior merge specs.
For motivation for this change, see https://github.com/sigp/lighthouse/pull/3244#issuecomment-1160963273
## Changes to `canonical_head` and `fork_choice`
Previously, the `BeaconChain` had two separate fields:
```
canonical_head: RwLock<Snapshot>,
fork_choice: RwLock<BeaconForkChoice>
```
Now, we have grouped these values under a single struct:
```
canonical_head: CanonicalHead {
cached_head: RwLock<Arc<Snapshot>>,
fork_choice: RwLock<BeaconForkChoice>
}
```
Apart from ergonomics, the only *actual* change here is wrapping the canonical head snapshot in an `Arc`. This means that we no longer need to hold the `cached_head` (`canonical_head`, in old terms) lock when we want to pull some values from it. This was done to avoid deadlock risks by preventing functions from acquiring (and holding) the `cached_head` and `fork_choice` locks simultaneously.
## Breaking Changes
### The `state` (root) field in the `finalized_checkpoint` SSE event
Consider the scenario where epoch `n` is just finalized, but `start_slot(n)` is skipped. There are two state roots we might in the `finalized_checkpoint` SSE event:
1. The state root of the finalized block, which is `get_block(finalized_checkpoint.root).state_root`.
4. The state root at slot of `start_slot(n)`, which would be the state from (1), but "skipped forward" through any skip slots.
Previously, Lighthouse would choose (2). However, we can see that when [Teku generates that event](

Fix per-slot timer in presence of clock changes (#3243)
## Issue Addressed
Fixes a timing issue that results in spurious fork choice notifier failures:
```
WARN Error signalling fork choice waiter slot: 3962270, error: ForkChoiceSignalOutOfOrder { current: Slot(3962271), latest: Slot(3962270) }, service: beacon
```
There’s a fork choice run that is scheduled to run at the start of every slot by the `timer`, which creates a 12s interval timer when the beacon node starts up. The problem is that if there’s a bit of clock drift that gets corrected via NTP (or a leap second for that matter) then these 12s intervals will cease to line up with the start of the slot. This then creates the mismatch in slot number that we see above.
Lighthouse also runs fork choice 500ms before the slot begins, and these runs are what is conflicting with the start-of-slot runs. This means that the warning in current versions of Lighthouse is mostly cosmetic because fork choice is up to date with all but the most recent 500ms of attestations (which usually isn’t many).
## Proposed Changes
Fix the per-slot timer so that it continually re-calculates the duration to the start of the next slot and waits for that.
A side-effect of this change is that we may skip slots if the per-slot task takes >12s to run, but I think this is an unlikely scenario and an acceptable compromise.

Call per_slot_task from a blocking thread (v2) (#3199)
*This PR was adapted from @pawanjay176's work in #3197.* ## Issue Addressed Fixes a regression in https://github.com/sigp/lighthouse/pull/3168 ## Proposed Changes https://github.com/sigp/lighthouse/pull/3168 added calls to `fork_choice` in `BeaconChain::per_slot_task` function. This leads to a panic as `per_slot_task` is called from an async context which calls fork choice, which then calls `block_on`. This PR changes the timer to call the `per_slot_task` function in a blocking thread. Co-authored-by: Pawan Dhananjay <pawandhananjay@gmail.com> |

Update to tokio 1.1 (#2172)
## Issue Addressed resolves #2129 resolves #2099 addresses some of #1712 unblocks #2076 unblocks #2153 ## Proposed Changes - Updates all the dependencies mentioned in #2129, except for web3. They haven't merged their tokio 1.0 update because they are waiting on some dependencies of their own. Since we only use web3 in tests, I think updating it in a separate issue is fine. If they are able to merge soon though, I can update in this PR. - Updates `tokio_util` to 0.6.2 and `bytes` to 1.0.1. - We haven't made a discv5 release since merging tokio 1.0 updates so I'm using a commit rather than release atm. **Edit:** I think we should merge an update of `tokio_util` to 0.6.2 into discv5 before this release because it has panic fixes in `DelayQueue` --> PR in discv5: https://github.com/sigp/discv5/pull/58 ## Additional Info tokio 1.0 changes that required some changes in lighthouse: - `interval.next().await.is_some()` -> `interval.tick().await` - `sleep` future is now `!Unpin` -> https://github.com/tokio-rs/tokio/issues/3028 - `try_recv` has been temporarily removed from `mpsc` -> https://github.com/tokio-rs/tokio/issues/3350 - stream features have moved to `tokio-stream` and `broadcast::Receiver::into_stream()` has been temporarily removed -> `https://github.com/tokio-rs/tokio/issues/2870 - I've copied over the `BroadcastStream` wrapper from this PR, but can update to use `tokio-stream` once it's merged https://github.com/tokio-rs/tokio/pull/3384 Co-authored-by: realbigsean <seananderson33@gmail.com> |

Represent slots in secs instead of millisecs (#2163)
## Issue Addressed NA ## Proposed Changes Copied from #2083, changes the config milliseconds_per_slot to seconds_per_slot to avoid errors when slot duration is not a multiple of a second. To avoid deserializing old serialized data (with milliseconds instead of seconds) the Serialize and Deserialize derive got removed from the Spec struct (isn't currently used anyway). This PR replaces #2083 for the purpose of fixing a merge conflict without requiring the input of @blacktemplar. ## Additional Info NA Co-authored-by: blacktemplar <blacktemplar@a1.net> |
