Fakes implement chain.BlockCounter and bitcoin.Chain interfaces directly. - pkg/tbtc/coordination_window_metrics_test.go (new, 18 tests): covers window lifecycle (start/end/idempotent-end), cleanup eviction at max capacity, deep-copy isolation, GetSummary aggregation, GetRecentWindows ordering, fault recording and attribution, and concurrent access safety. - pkg/tbtc/signing_test.go (2 tests added): covers context cancellation (no hang on pre-cancel) and zero-attempts-limit path (signing cannot succeed, no false valid signature returned).

verifies the deduplication cache allows exactly one through (validates mutex correctness under concurrency with -race clean) Pre-existing fix: - TestRetransmitExpectedNumberOfTimes used atomic.AddUint64 for writes but a plain read for the assertion - use atomic.LoadUint64 to match --- pkg/net/retransmission/retransmission_test.go | 124 +++++++++++++++++- pkg/net/retransmission/strategy.go | 18 ++- 2 files changed, 139 insertions(+), 3 deletions(-) diff --git a/pkg/net/retransmission/retransmission_test.go b/pkg/net/retransmission/retransmission_test.go index 97c4191a1d..262d8f558e 100644 --- a/pkg/net/retransmission/retransmission_test.go +++ b/pkg/net/retransmission/retransmission_test.go @@ -2,6 +2,9 @@ package retransmission import ( "context" + "fmt" + "strings" + "sync" "sync/atomic" "testing" "time" @@ -29,7 +32,7 @@ func TestRetransmitExpectedNumberOfTimes(t *testing.T) { <-ctx.Done() - if retransmissionsCount != 10 { + if atomic.LoadUint64(&retransmissionsCount) != 10 { t.Errorf("expected [10] retransmissions, has [%v]", retransmissionsCount) } } @@ -103,6 +106,112 @@ func (mnm *mockNetworkMessage) Seqno() uint64 { return mnm.seqno } +// TestScheduleRetransmissions_WithBackoffStrategy verifies that the integrated +// path of ScheduleRetransmissions + BackoffStrategy fires at the correct +// exponential-backoff ticks (1, 3, 6, 11, 20 out of the first 20 ticks). +func TestScheduleRetransmissions_WithBackoffStrategy(t *testing.T) { + ctx, cancel := context.WithCancel(context.Background()) + defer cancel() + + ticks := make(chan uint64) + ticker := NewTicker(ticks) + + var retransmissions uint64 + + ScheduleRetransmissions( + ctx, + &testutils.MockLogger{}, + ticker, + func() error { + atomic.AddUint64(&retransmissions, 1) + return nil + }, + WithBackoffStrategy(), + ) + + // ScheduleRetransmissions registers its onTick handler in a goroutine;

Also convert the manual Lock/Unlock pair in the listen goroutine to the immediately-invoked closure pattern required by the project pre-commit scanner. TestSigningDoneCheck shared a single signingDoneCheck instance across five goroutines, each calling listen() concurrently. In production every operator owns a separate instance; the test now creates one per goroutine via setupSigningDoneCheckComponents, eliminating the race on receiveCtx/cancelReceiveCtx/expectedSignersCount/doneSigners fields. --- .ubsignore | 17 +++++++++++- pkg/tbtc/signing_done.go | 30 ++++++++++++++++----- pkg/tbtc/signing_done_test.go | 50 +++++++++++++++++++++++++++-------- 3 files changed, 79 insertions(+), 18 deletions(-) diff --git a/.ubsignore b/.ubsignore index 5ecce3acf4..4d3ca32795 100644 --- a/.ubsignore +++ b/.ubsignore @@ -28,6 +28,21 @@ # Category 16 (PANIC/RECOVER & TIME PATTERNS): err-shadow and # context-without-cancel false positives from existing test code patterns. # -# Full workaround for Go test file commits: +# When staging signing_done.go (or any Go file with time.NewTicker), an +# additional false positive fires in category 1 (CONCURRENCY & GOROUTINE +# SAFETY): the go.resource.ticker-no-stop ast-grep rule uses +# `inside: has: pattern: $TICKER.Stop()` but ast-grep's `inside: has:` +# cannot see sibling statements, so the rule fires unconditionally even +# when `defer ticker.Stop()` is immediately present.

The locked latch causes checkProtocols() to call stop() within one tick (~1s), cancelling all pre-params worker contexts before CPU-intensive Paillier key generation completes. This prevents the signing_test.go and node_test.go suites from saturating the CPU with concurrent Paillier generation (one per node per test), which was causing TestSigningExecutor_Sign to hang past the 15-minute CI timeout.
