Finding 1: Identity no longer address-derived - ReplicaAddr.ServerID field added (stable server identity from registry) - BlockVolumeAssignment.ReplicaServerID field added (scalar RF=2 path) - ControlBridge uses ServerID, NOT address, for ReplicaID - Missing ServerID → replica skipped (fail closed), logged Finding 2: Wired into real ProcessAssignments - BlockService.v2Bridge field initialized in StartBlockService - ProcessAssignments converts each assignment via v2Bridge.ConvertAssignment BEFORE existing V1 processing (parallel, not replacing yet) - Logged at glog V(1) Finding 3: Fail-closed on missing identity - Empty ServerID in ReplicaAddrs → replica skipped with log - Empty ReplicaServerID in scalar path → no replica created - Test: MissingServerID_FailsClosed verifies both paths 7 tests: StableServerID, AddressChange_IdentityPreserved, MultiReplica_StableServerIDs, MissingServerID_FailsClosed, EpochFencing_IntegratedPath, RebuildAssignment, ReplicaAssignment Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
V2 Prototype
Experimental WAL V2 prototype code lives here.
Current prototype:
fsmv2/: pure in-memory replication FSM prototypevolumefsm/: volume-level orchestrator prototype abovefsmv2distsim/: early distributed/data-correctness simulator with synthetic 4K block values
Rules:
- do not wire this directly into WAL V1 production code
- keep interfaces and tests focused on architecture learning
- promote pieces into production only after V2 design stabilizes
Windows test workflow
Because normal go test may be blocked by Windows Defender when it executes temporary test binaries from %TEMP%, use:
powershell -ExecutionPolicy Bypass -File .\sw-block\prototype\run-tests.ps1
This builds test binaries into the workspace and runs them directly.
