From 0765eb4de3da7c7fcd1a6e4144bd525da19ed777 Mon Sep 17 00:00:00 2001 From: Joseph Doherty Date: Thu, 30 Apr 2026 16:37:12 -0400 Subject: [PATCH] clients/dotnet: SDK methods for AcknowledgeAlarm + QueryActiveAlarms (PR E.2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Seventh PR of the alarms-over-gateway epic (docs/plans/alarms-over-gateway.md). Depends on PR A.1 (proto, merged) and E.1 (regen, merged). Hand-written .NET SDK methods on top of the regenerated proto types: - MxGatewayClient.AcknowledgeAlarmAsync — routes through the existing safe-unary retry pipeline (Acks are idempotent at MxAccess), maps Unauthenticated/PermissionDenied RpcExceptions to typed MxGatewayAuthenticationException / MxGatewayAuthorizationException via GrpcMxGatewayClientTransport.MapRpcException. - MxGatewayClient.QueryActiveAlarmsAsync — server-streaming IAsyncEnumerable mirroring the StreamEvents pattern. - IMxGatewayClientTransport extended; GrpcMxGatewayClientTransport implements both methods using the regenerated grpc client. - FakeGatewayTransport extended with capture lists, exception queue, and reply / snapshot enqueue helpers. CLI version-string assertions updated for the GatewayProtocolVersion 2 → 3 bump from A.1. The CLI alarms verb (subscribe / acknowledge / query-active) is deferred to a follow-up — keeping this PR focused on the SDK surface that lmxopcua's GalaxyDriver consumes in PR B.2. The other-language SDKs (E.3-E.6) layer the same shape on the regen. Tests: - 6 new MxGatewayClientAlarmsTests — request shape, cancellation honor (linked-token via retry pipeline), Unauthenticated mapping, streaming snapshot enumeration, filter prefix passthrough, cancellation during enumeration. - Full client test suite: 57 passed (was 51; 6 new).
