From 77a6e60fa37d7f3b3a844748b3f8bda8a7383cbf Mon Sep 17 00:00:00 2001 From: pingqiu Date: Tue, 31 Mar 2026 15:46:48 -0700 Subject: [PATCH] =?UTF-8?q?feat:=20add=20P3=20hardening=20validation=20?= =?UTF-8?q?=E2=80=94=204=20matrix=20+=202=20extra=20cases=20(Phase=2008)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Compact replay matrix on accepted P1/P2 live path: Matrix 1 (ChangedAddress): address change → cancel old plan → new assignment → new recovery → identity preserved → pins released Matrix 2 (StaleEpoch): epoch bump → invalidate → cancel plan → new epoch assignment → new session → pins released Matrix 3 (NeedsRebuild): unrecoverable gap → rebuild assignment → RebuildExecutor(IO=v2bridge) → InSync → pins released Matrix 4 (PostCheckpointBoundary): at committed=ZeroGap, in window= CatchUp via CatchUpExecutor(IO=v2bridge) → pins released Extra 1 (FailoverCycle): epoch 1 → failover → epoch 2 → recovery resumes → InSync. Logs: invalidation + cancellation + new session. Extra 2 (OverlappingRetention): plan1 acquires pins → cancel → plan2 acquires pins → cancel → ActiveHoldCount==0, MinWALRetentionFloor has no holds. Each test verifies all 5 evidence categories: entry truth, engine result, execution result, cleanup, observability Co-Authored-By: Claude Opus 4.6 (1M context) --- .../blockvol/v2bridge/hardening_test.go | 372 ++++++++++++++++++ 1 file changed, 372 insertions(+) create mode 100644 weed/storage/blockvol/v2bridge/hardening_test.go diff --git a/weed/storage/blockvol/v2bridge/hardening_test.go b/weed/storage/blockvol/v2bridge/hardening_test.go new file mode 100644 index 000000000..a0646cc50 --- /dev/null +++ b/weed/storage/blockvol/v2bridge/hardening_test.go @@ -0,0 +1,372 @@ +package v2bridge + +import ( + "testing" + + bridge "github.com/seaweedfs/seaweedfs/sw-block/bridge/blockvol" + engine "github.com/seaweedfs/seaweedfs/sw-block/engine/replication" +) + +// ============================================================ +// Phase 08 P3: Hardening validation on accepted P1/P2 live path +// +// Replay matrix (4 cases) + 2 extra cases. +// Each test proves entry truth → engine result → execution result +// → cleanup result → observability result as ONE verification. +// ============================================================ + +func setupHardening(t *testing.T) (*engine.RecoveryDriver, *bridge.ControlAdapter, *Reader, *Executor, *Pinner) { + t.Helper() + vol := createTestVol(t) + t.Cleanup(func() { vol.Close() }) + + reader := NewReader(vol) + pinner := NewPinner(vol) + executor := NewExecutor(vol) + + sa := bridge.NewStorageAdapter(&readerShim{reader}, &pinnerShim{pinner}) + ca := bridge.NewControlAdapter() + driver := engine.NewRecoveryDriver(sa) + + return driver, ca, reader, executor, pinner +} + +// --- Matrix 1: Changed-address restart --- + +func TestP3_Matrix_ChangedAddress(t *testing.T) { + driver, ca, reader, executor, pinner := setupHardening(t) + vol := reader.vol + + for i := 0;
