fix: report jailed validators in peer-type cache and heartbeat metrics#126MathijsBok wants to merge 6 commits into
Conversation
WalkthroughThe coordinator now persists and restores leaving validators, exposes their keys, and supplies them to peer caches. Jailed peers receive distinct classification, heartbeat retention, and metric behavior. Mocks, disabled implementations, and tests support the expanded interface. ChangesLeaving Validator Flow
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds jailed-validator state to persistence and heartbeat classification. It is mergeable with owner awareness, but several test paths still discard errors and rely on fixed sleeps, which can mask failures or create CI flakiness; these are bounded test-reliability issues rather than a demonstrated production defect.

Learning: In Go structs that are JSON-marshaled, if a field is a `bool` and has the `json:"...,omitempty"` tag, then leaving that field at its zero value (`false`) is functionally equivalent (in the resulting JSON) to explicitly setting `Foundation: false`. Reviewers should not flag struct literals that omit such `bool` fields as an inconsistency; they will serialize identically because `omitempty` suppresses `false` values.

Learning: In Go, the pattern `append([]byte(nil), src...)` should be treated as preserving nil identity when `src` is a nil `[]byte`: spreading a nil slice contributes zero variadic arguments, so `append` performs no allocation and returns the original nil destination slice unchanged (i.e., result is nil, not an empty non-nil slice). Do not flag this as an incorrect empty-slice conversion; it intentionally maintains `nil`.

Replace the copy-pasted getter/log/seed blocks in
PeerTypeProvider.createNewCache and validatorsProvider.createNewCache
with a table of {name, peerType, getter} and one loop, so adding a list
cannot silently pair the wrong peer type with a getter. Semantics are
preserved exactly: the peerTypeProvider keeps fail-fast (any getter
error keeps the previous cache, log.Warn with the error), the
validatorsProvider keeps its soft-fail overlay (log.Debug, trie-based
cache still served). A new test pins the soft-fail contract, and the
empty epoch-start prepare handler gets the same explanatory comment as
the peerTypeProvider sibling (sonar go:S1186).
Refs #118
The nodes coordinator builds a leaving list (validators whose list is jailed) but discarded it: EpochStartPrepare never passed it to SetNodes and the registry did not persist it, so the peer-type cache could not see jailed validators. They reported observer everywhere and dropped out of /node/heartbeatstatus after the hide interval. The coordinator now stores the computed leaving list on the epoch config (SetNodes gained a leaving parameter), persists it in the registry as leavingValidators (old registries without the field restore an empty list and converge at the next epoch start), and exposes it through GetAllLeavingValidatorsKeys on sharding.NodesCoordinator. The peer-type cache seeds that list first, labeled jailed, so the working lists win on any overlap; the numToStay promotion keeps the lists a partition in production. Consumers follow three explicit predicate tiers: jailed does not count toward klv_live_validator_nodes (the working set is unchanged), and the new isRegisteredValidatorPeerType shields jailed entries from heartbeat Cleanup and makes the node self-report klv_node_type=validator with klv_peer_type=jailed. The dead GetAllLeavingValidatorsPublicKeys mock lookalikes are replaced by hooks matching the real getter. Refs #116
… tests Addresses the pre-push code review findings on this branch: - the four GetAllXValidatorsKeys getters in sharding/nodesCoordinator.go were verbatim copies differing in one field access; they now share a single getAllValidatorsKeys helper so the epoch lookup and the locking discipline live in one place (flagged independently by two reviewers, and ~21 duplicated new-code lines risked the SonarQube duplication gate for new code) - the ownerKey leg of the SetNodes leaving-list test compared nils because the validator mock drops its owner argument; the test now builds real validators with distinct owner addresses - a new heartbeat test discarded the constructor error, against the repo convention of asserting setup errors; it now uses require.NoError - the mock GetAllLeavingValidatorsKeys parameter was misnamed includeLeaving (copied from its siblings); renamed to ownerKey to match the interface semantics - the only uncovered changed statement (the error branch restoring a malformed leaving validator from the registry) is now pinned by TestNodesCoordinator_LoadStateWithMalformedLeavingValidatorFails Refs #116, #118
Two nits from the pre-push gate review round: - the validatorsProvider overlay Debug log dropped the error value while the equivalent peerTypeProvider log includes it; a failing overlay in production was undiagnosable (errors are never silently discarded) - the seeding-precedence comment in the peerTypeProvider scenario test sat above the jailed-only assertion instead of the elected1 assertion that actually proves working lists win over the leaving list Refs #116, #118
…tor complexity The SonarQube quality gate on the PR flagged go:S3776 on createNodesCoordinator (cognitive complexity 35, limit 15) because this branch touched the function; the complexity itself is long-standing. The function now delegates to three helpers: genesisValidators (initial nodes conversion), registryEpochValidators (one registry epoch entry to validator lists) and seedPreviousEpochFromRegistry (previous-epoch SetNodes seeding behind a small epochNodesSetter interface, since SetNodes is not part of sharding.NodesCoordinator). Cognitive complexity of the main function drops to about 13, each helper stays in single digits. One deliberate strictness increase: the current-epoch registry entry is now converted through the same helper, so malformed waiting or leaving entries fail node construction instead of surfacing later; LoadState already rejects the same data, the failure just moves earlier. The current epoch still seeds only elected and eligible into the constructor arguments, unchanged (the comment points to the LoadState restore). Refs #116
…e at epoch zero Two CodeRabbit findings on the helpers extracted in the previous commit, both pre-existing behavior that moved onto the new lines: - a registry entry can be present but null in the stored JSON, so the map lookup succeeds and the conversion dereferenced nil and panicked during bootstrap; registryEpochValidators now returns an error for a nil entry, so both current-epoch construction and previous-epoch restoration fail safely - at epoch 0 the previous-epoch calculation wrapped around to 4294967295, so a registry entry under that key would be restored as the previous epoch; seedPreviousEpochFromRegistry now returns before the subtraction, and the computed epoch is reused for the SetNodes call instead of recomputing it Refs #116

Summary
Closes #116. Closes #118.
A jailed validator's key never reached the heartbeat peer-type cache, so its node reported
klv_node_type=observerandklv_peer_type=observer, and its heartbeat entry disappeared from/node/heartbeatstatusafterHideInactiveValidatorIntervalInSec. Root cause: the nodes coordinator computed its leaving list (validators withList == jailedincomputeNodesConfigFromList) but then discarded it.EpochStartPreparenever handed it toSetNodes,epochNodesConfig.leavingListwas always empty, and the registry did not persist it, so the list was unreachable for the peer-type cache in every scenario (live, epoch start, restart).What changed
Commit 1 (5cc8f9d, #118):
PeerTypeProvider.createNewCacheandvalidatorsProvider.createNewCacheare now table-driven ({name, peerType, getter}plus one loop), so adding a list is one data row instead of an error-prone copy-paste. Semantics preserved exactly: the peerTypeProvider keeps fail-fast (any getter error keeps the previous cache,log.Warnwith the error), the validatorsProvider keeps its soft-fail overlay. A new subtest pins the soft-fail contract (failing getter keeps trie-based cache and remaining overlays), and the empty epoch-start prepare handler got the same explanatory comment as its sibling (sonar go:S1186).Commit 2 (49067cc, #116): the coordinator now stores, persists and exposes the leaving list, and the peer-type surface consumes it:
SetNodesgained aleavingparameter and stores it on the epoch config;EpochStartPreparepassesnewNodesConfig.leavingList(sharding/nodesCoordinator.go).leavingValidatorsandLoadState/the bootstrap path incmd/node/node.gorestore it.GetAllLeavingValidatorsKeys(epoch, ownerKey)onsharding.NodesCoordinator; all implementers updated, and the deadGetAllLeavingValidatorsPublicKeysmock lookalikes (different name and signature, zero callers) were removed.PeerTypeProvider.createNewCacheseeds the leaving list first, labeledcore.JailedList; working lists win on any overlap (the numToStay promotion keeps the lists a partition in production).isRegisteredValidatorPeerType(node/heartbeat/process/heartbeatMessageInfo.go) drives Cleanup shielding (monitor.goshouldSkipValidator) andklv_node_typeself-reporting (sender.goupdateMetrics). The gauges are unchanged.Commit 3 (015b05f): fixes from the first review round: the four
GetAllXValidatorsKeysgetters were consolidated behind onegetAllValidatorsKeyshelper (flagged independently by two reviewers; the fourth copy also risked the SonarQube duplicated-lines gate on new code), the ownerKey test leg now uses real validators with distinct owner addresses (the validator mock drops its owner argument, making the old assertion vacuous), a discarded constructor error in a new test is now asserted, the mock parameterincludeLeavingwas renamed toownerKey, and a new test pins that a malformed leaving validator in the registry failsLoadStatewithErrNilPubKey.Commit 4 (bd6804b): gate-review nits: the overlay
log.Debugnow includes the error value (errors are never silently discarded), and the precedence comment in the provider scenario test moved to the assertion that actually proves it.Commit 5 (abfa934): the SonarQube quality gate failed on
go:S3776forcreateNodesCoordinator(cognitive complexity 35, limit 15). The complexity is long-standing, but this branch touched the function, so Sonar counts it as new code. It now delegates to three helpers:genesisValidators(initial nodes conversion),registryEpochValidators(one registry epoch entry to validator lists) andseedPreviousEpochFromRegistry(previous-epochSetNodesseeding behind a smallepochNodesSetterinterface, sinceSetNodesis not part ofsharding.NodesCoordinator). Complexity of the main function drops to about 13, each helper stays in single digits. One deliberate strictness increase: the current-epoch registry entry now goes through the same helper, so malformed waiting or leaving entries fail node construction instead of surfacing later inLoadState, which rejected the same data anyway. The current epoch still seeds only elected and eligible into the constructor arguments, unchanged.Commit 6 (2246113): two latent bootstrap bugs surfaced by the review of commit 5, both pre-existing behavior that moved onto the new lines:
EpochsConfigis amap[string]*EpochValidators, so a stored registry containing"5": nullmakes the lookup succeed with a nil pointer and the conversion panicked during node construction.registryEpochValidatorsnow returns an error for a nil entry, covering both call sites, so startup fails cleanly.4294967295, so a registry entry under that key could be restored as the previous epoch.seedPreviousEpochFromRegistrynow returns before the subtraction, and the computed epoch is reused for theSetNodescall.Design decisions
klv_live_validator_nodes: the gauge remains the working set (elected, eligible, waiting).klv_node_type=validator; the punished state is visible asklv_peer_type=jailed.jailed, notleaving: the coordinator fills the leaving list exclusively fromList == jailed, and/validator/statisticsalready reportsjailedfrom the trie.The predicate tiers are now: consensus-capable (elected, eligible) inside working validators (plus waiting) inside registered validators (plus jailed), one predicate per tier, with the consumers documented at the definitions.
Compatibility
