Disallow attestation production earlier than head (#2130) ## Issue Addressed The non-finality period on Pyrmont between epochs [`9114`](https://pyrmont.beaconcha.in/epoch/9114) and [`9182`](https://pyrmont.beaconcha.in/epoch/9182) was contributed to by all the `lighthouse_team` validators going down. The nodes saw excessive CPU and RAM usage, resulting in the system to kill the `lighthouse bn` process. The `Restart=on-failure` directive for `systemd` caused the process to bounce in ~10-30m intervals. Diagnosis with `heaptrack` showed that the `BeaconChain::produce_unaggregated_attestation` function was calling `store::beacon_state::get_full_state` and sometimes resulting in a tree hash cache allocation. These allocations were approximately the size of the hosts physical memory and still allocated when `lighthouse bn` was killed by the OS. There was no CPU analysis (e.g., `perf`), but the `BeaconChain::produce_unaggregated_attestation` is very CPU-heavy so it is reasonable to assume it is the cause of the excessive CPU usage, too. ## Proposed Changes `BeaconChain::produce_unaggregated_attestation` has two paths: 1. Fast path: attesting to the head slot or later. 2. Slow path: attesting to a slot earlier than the head block. Path (2) is the only path that calls `store::beacon_state::get_full_state`, therefore it is the path causing this excessive CPU/RAM usage. This PR removes the current functionality of path (2) and replaces it with a static error (`BeaconChainError::AttestingPriorToHead`). This change reduces the generality of `BeaconChain::produce_unaggregated_attestation` (and therefore [`/eth/v1/validator/attestation_data`](https://ethereum.github.io/eth2.0-APIs/#/Validator/produceAttestationData)), but I argue that this functionality is an edge-case and arguably a violation of the [Honest Validator spec](https://github.com/ethereum/eth2.0-specs/blob/dev/specs/phase0/validator.md). It's possible that a validator goes back to a prior slot to "catch up" and submit some missed attestations. This change would prevent such behaviour, returning an error. My concerns with this catch-up behaviour is that it is: - Not specified as "honest validator" attesting behaviour. - Is behaviour that is risky for slashing (although, all validator clients *should* have slashing protection and will eventually fail if they do not). - It disguises clock-sync issues between a BN and VC. ## Additional Info It's likely feasible to implement path (2) if we implement some sort of caching mechanism. This would be a multi-week task and this PR gets the issue patched in the short term. I haven't created an issue to add path (2), instead I think we should implement it if we get user-demand.

Fix head tracker concurrency bugs (#1771) ## Issue Addressed Closes #1557 ## Proposed Changes Modify the pruning algorithm so that it mutates the head-tracker _before_ committing the database transaction to disk, and _only if_ all the heads to be removed are still present in the head-tracker (i.e. no concurrent mutations). In the process of writing and testing this I also had to make a few other changes: * Use internal mutability for all `BeaconChainHarness` functions (namely the RNG and the graffiti), in order to enable parallel calls (see testing section below). * Disable logging in harness tests unless the `test_logger` feature is turned on And chose to make some clean-ups: * Delete the `NullMigrator` * Remove type-based configuration for the migrator in favour of runtime config (simpler, less duplicated code) * Use the non-blocking migrator unless the blocking migrator is required. In the store tests we need the blocking migrator because some tests make asserts about the state of the DB after the migration has run. * Rename `validators_keypairs` -> `validator_keypairs` in the `BeaconChainHarness` ## Testing To confirm that the fix worked, I wrote a test using [Hiatus](https://crates.io/crates/hiatus), which can be found here: https://github.com/michaelsproul/lighthouse/tree/hiatus-issue-1557 That test can't be merged because it inserts random breakpoints everywhere, but if you check out that branch you can run the test with: ``` $ cd beacon_node/beacon_chain $ cargo test --release --test parallel_tests --features test_logger ``` It should pass, and the log output should show: ``` WARN Pruning deferred because of a concurrent mutation, message: this is expected only very rarely! ``` ## Additional Info This is a backwards-compatible change with no impact on consensus.

Disallow attestation production earlier than head (#2130) ## Issue Addressed The non-finality period on Pyrmont between epochs [`9114`](https://pyrmont.beaconcha.in/epoch/9114) and [`9182`](https://pyrmont.beaconcha.in/epoch/9182) was contributed to by all the `lighthouse_team` validators going down. The nodes saw excessive CPU and RAM usage, resulting in the system to kill the `lighthouse bn` process. The `Restart=on-failure` directive for `systemd` caused the process to bounce in ~10-30m intervals. Diagnosis with `heaptrack` showed that the `BeaconChain::produce_unaggregated_attestation` function was calling `store::beacon_state::get_full_state` and sometimes resulting in a tree hash cache allocation. These allocations were approximately the size of the hosts physical memory and still allocated when `lighthouse bn` was killed by the OS. There was no CPU analysis (e.g., `perf`), but the `BeaconChain::produce_unaggregated_attestation` is very CPU-heavy so it is reasonable to assume it is the cause of the excessive CPU usage, too. ## Proposed Changes `BeaconChain::produce_unaggregated_attestation` has two paths: 1. Fast path: attesting to the head slot or later. 2. Slow path: attesting to a slot earlier than the head block. Path (2) is the only path that calls `store::beacon_state::get_full_state`, therefore it is the path causing this excessive CPU/RAM usage. This PR removes the current functionality of path (2) and replaces it with a static error (`BeaconChainError::AttestingPriorToHead`). This change reduces the generality of `BeaconChain::produce_unaggregated_attestation` (and therefore [`/eth/v1/validator/attestation_data`](https://ethereum.github.io/eth2.0-APIs/#/Validator/produceAttestationData)), but I argue that this functionality is an edge-case and arguably a violation of the [Honest Validator spec](https://github.com/ethereum/eth2.0-specs/blob/dev/specs/phase0/validator.md). It's possible that a validator goes back to a prior slot to "catch up" and submit some missed attestations. This change would prevent such behaviour, returning an error. My concerns with this catch-up behaviour is that it is: - Not specified as "honest validator" attesting behaviour. - Is behaviour that is risky for slashing (although, all validator clients *should* have slashing protection and will eventually fail if they do not). - It disguises clock-sync issues between a BN and VC. ## Additional Info It's likely feasible to implement path (2) if we implement some sort of caching mechanism. This would be a multi-week task and this PR gets the issue patched in the short term. I haven't created an issue to add path (2), instead I think we should implement it if we get user-demand.

let block = chain
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 :wastebasket:. ## 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.

Fix head tracker concurrency bugs (#1771) ## Issue Addressed Closes #1557 ## Proposed Changes Modify the pruning algorithm so that it mutates the head-tracker _before_ committing the database transaction to disk, and _only if_ all the heads to be removed are still present in the head-tracker (i.e. no concurrent mutations). In the process of writing and testing this I also had to make a few other changes: * Use internal mutability for all `BeaconChainHarness` functions (namely the RNG and the graffiti), in order to enable parallel calls (see testing section below). * Disable logging in harness tests unless the `test_logger` feature is turned on And chose to make some clean-ups: * Delete the `NullMigrator` * Remove type-based configuration for the migrator in favour of runtime config (simpler, less duplicated code) * Use the non-blocking migrator unless the blocking migrator is required. In the store tests we need the blocking migrator because some tests make asserts about the state of the DB after the migration has run. * Rename `validators_keypairs` -> `validator_keypairs` in the `BeaconChainHarness` ## Testing To confirm that the fix worked, I wrote a test using [Hiatus](https://crates.io/crates/hiatus), which can be found here: https://github.com/michaelsproul/lighthouse/tree/hiatus-issue-1557 That test can't be merged because it inserts random breakpoints everywhere, but if you check out that branch you can run the test with: ``` $ cd beacon_node/beacon_chain $ cargo test --release --test parallel_tests --features test_logger ``` It should pass, and the log output should show: ``` WARN Pruning deferred because of a concurrent mutation, message: this is expected only very rarely! ``` ## Additional Info This is a backwards-compatible change with no impact on consensus.
