From 48b3e1b8c867c844bbcd1ae16b5ea222778b3c93 Mon Sep 17 00:00:00 2001 From: pingqiu Date: Tue, 31 Mar 2026 10:35:41 -0700 Subject: [PATCH] feat: add real control delivery bridge from BlockVolumeAssignment (Phase 08 P1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ControlBridge converts real BlockVolumeAssignment (from master heartbeat) into V2 engine AssignmentIntent: - Identity: ReplicaID = / - Epoch from real assignment - Role → SessionKind mapping (primary/replica/rebuilding) - Multi-replica support (ReplicaAddrs) with scalar RF=2 fallback Known limitation (documented in test): - extractServerID currently uses address as server ID (matches master registry ReplicaInfo.Server format) - IP change = different server ID in current model - Registry-backed stable server ID deferred 6 new tests: - PrimaryAssignment_StableIdentity: real assignment → stable ID - PrimaryAssignment_MultiReplica: RF=3 multi-replica mapping - AddressChange_SameServerID: documents current identity boundary - EpochFencing_IntegratedPath: epoch 1 → bump → epoch 2 through real assignment conversion + engine - RebuildAssignment: rebuilding role → SessionRebuild - ReplicaAssignment: replica role with local server ID Delivery template: Changed contracts: real BlockVolumeAssignment → engine intent Fail-closed: unknown role returns empty intent Carry-forward: address-based server ID, not registry-backed Co-Authored-By: Claude Opus 4.6 (1M context) --- weed/storage/blockvol/v2bridge/control.go | 150 +++++++++++ .../storage/blockvol/v2bridge/control_test.go | 242 ++++++++++++++++++ 2 files changed, 392 insertions(+) create mode 100644 weed/storage/blockvol/v2bridge/control.go create mode 100644 weed/storage/blockvol/v2bridge/control_test.go diff --git a/weed/storage/blockvol/v2bridge/control.go b/weed/storage/blockvol/v2bridge/control.go new file mode 100644 index 000000000..b2636e336 --- /dev/null +++ b/weed/storage/blockvol/v2bridge/control.go @@ -0,0 +1,150 @@ +// control.go implements the real control-plane delivery bridge. +// It converts BlockVolumeAssignment (from master heartbeat) into +// V2 engine AssignmentIntent, using real master/registry identity. +// +// Identity rule: ReplicaID = / +// The replica-server is the VS identity from the master registry, +// not a transport address.
