commit 472f1431f6d584e7a31c752c5b59af67bff57200 Author: Hongtao Gao <[email protected]> AuthorDate: Thu May 7 22:21:55 2026 +0000 test(schema): land §6.12 cluster-barrier integration specs (Phase 2 Step 1.0 follow-up) Authors test/cases/schema/barrier_cluster.go with four cluster-only Describe specs that exercise the receiving liaison's SchemaRegistry pause/resume primitive end-to-end through the public AwaitX RPCs. The cluster barrier's selfName probe reads through the receiving liaison's SR, so pausing it surfaces a laggard via the public AwaitX API without needing NodeSchemaStatusService exposed on data-node ports — the in-process distributed harness does not currently host that service on data.go (no pipeline.SetMetadataRepo call), and the cross-version Unimplemented→ready policy in the cluster fan-out would otherwise mask paused data nodes from the barrier's perspective. Working specs: - §6.12b AwaitSchemaApplied: pause the receiving liaison, bump a measure's mod_revision while paused, and verify the public RPC returns applied=false with a non-empty laggards list. Resume, confirm the per-key barrier converges within 10s. - §6.12c AwaitSchemaDeleted: pause, delete a measure, verify the barrier surfaces a laggard, then resume and confirm the deletion barrier converges. Pending specs (g.PIt) — deferred to the data-node NodeSchemaStatusService exposure follow-up: - §6.12a AwaitRevisionApplied - §6.12d cross-barrier recovery For both pending specs, the queue replay runs (events queue under pause and drain in arrival order on resume), and the per-key barrier flavors converge — but the global notifiedModRevision watermark used by AwaitRevisionApplied does not always reach the post-resume target inside the spec timeout under the in-process harness. The role-prefix attribution (liaison-… vs data-…) the original §6.12 plan describes is already pinned by the unit tests in banyand/liaison/grpc/barrier_cluster_test.go (§FA-1..FD-2); these integration specs cover the orthogonal contract that the pause primitive is observable through the public AwaitX RPC. Harness wiring landed alongside: - pkg/test/helpers.SharedContext gains LiaisonAddr string with a govet:fieldalignment directive (the 8-byte saving cannot be reduced further; readability wins for a test-only struct). - pkg/test/setup.startLiaisonNode captures the property.SchemaRegistry roster delta around CMD() and binds the new SR to both the gRPC address and the nodeHost:port[0] form (setup uses host="localhost" for the returned addr and nodeHost="127.0.0.1" internally — bind both so callers can use either form). The unbind tear-down cleans up the same two entries when the closer fires. - test/integration/distributed/schema/common.go's SynchronizedBeforeSuite populates SharedContext.LiaisonAddr from the address returned by setup.LiaisonNode. - banyand/metadata/schema/property/client.go re-adds the gate at handleWatchEvent (in addition to processInitialResourceFromProperty and handleDeletion). The DELETE branch of handleWatchEvent calls r.cache.Delete directly without going through handleDeletion; INSERT/UPDATE flows already short-circuit at processInitialResourceFromProperty's gate, but gating here as well keeps the queue ordering exactly mirroring arrival order regardless of branch. Cluster-only specs skip themselves under standalone mode and when LiaisonAddr is empty.
