From 64fa3fdb03aaa93456b067fbcd0f07ad5bfac38f Mon Sep 17 00:00:00 2001 From: Copilot <223556219+Copilot@users.noreply.github.com> Date: Thu, 14 May 2026 06:35:05 +0200 Subject: [PATCH 01/99] Support framework for the OPC UA Conformance Test (CTT) NUnit parity suite MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This change extracts the SDK / reference-server / test-infrastructure work needed by the upcoming Opc.Ua.Conformance.Tests project (PR #3750) into a stand-alone change set that can be merged independently. ### Server framework (Libraries/Opc.Ua.Server) * `IRoleManager` and the default `RoleManager` implementation (`RoleBasedUserManagement/`) — extensibility surface for OPC UA Part 18 role / identity-mapping with built-in dedup on `GrantedRoleIds`. * `RoleStateBinding` — wires the well-known role nodes (Observer / Operator / Engineer / Supervisor / ConfigureAdmin / SecurityAdmin) and the `RoleSet.AddRole` / `RemoveRole` methods through to an `IRoleManager`. * `IServerInternal.RoleManager` / `ISessionManager` plumbing so the `SessionManager` can resolve dynamic roles via `RoleBasedIdentity.WithAdditionalRoles` on every session activation. * `DiagnosticsNodeManager`: keep `Server.ServerDiagnostics.SamplingIntervalDiagnosticsArray` populated with an empty `Good` array (Part 5 §6.4.7) instead of returning `BadNodeIdUnknown`; expose `IDiagnosticsNodeManager.FindPredefinedNode`. * `ServerInternalData`: populate `Server.ServerCapabilities.MaxSubscriptionsPerSession` (Part 5 §6.3), fix dynamic-change of `EnabledFlag` to pass CTT, expose a few internal hooks needed by the reference-server NodeManager. ### Stack hooks (Stack/Opc.Ua.Core) * `IServiceResponseMutator` + `ServerBase.ResponseMutator` — test-only hook on `EndpointBase.EndpointIncomingRequest.CallAsync` that lets a controller mutate any service response (used by the conformance suite's `MockResponseController` to inject Bad_X codes without an external mock server). ### Reference server (Applications/Quickstarts.Servers, ConsoleReferenceServer) * `ReferenceServerConfigurationNodeManager` + `ReferenceServerMainNodeManagerFactory` — CTT-only address-space tweaks (RolePermissions / EngineeringUnits / AddIn instance) kept outside the SDK and wired through the server's `CreateMainNodeManagerFactory` override. * `RoleManagementHandler` — full Part 18 RoleManager wire-up for the reference server, exposing the AddIdentity / RemoveIdentity / AddApplication / RemoveApplication / AddEndpoint / RemoveEndpoint method handlers. * `AliasNameNodeManager` + `AliasNameWildcardMatcher` — Part 17 AliasName service implementation. * `FileSystem/*` — Part 20 FileSystem service implementation (`FileSystemServer`, `FileSystemNodeManager`, `FileObjectState`, `DirectoryObjectState`, `DirectoryBrowser`, `FileHandle`). * `Opc.Ua.Lds.Server` library — new in-tree Local Discovery Server implementation (LdsServer, MulticastDiscovery, RegisteredServerStore, RegistrationEntry, ServerOnNetworkRecord). * `ConsoleLdsServer` — sample host for the new LDS library. * Reference-server ReferenceNodeManager updates (RolePermissions on static scalars, conformance-friendly historical-access wiring, etc.). ### Source generator (Tools/Opc.Ua.SourceGeneration.Core) * `NodeStateGenerator`: emit additional state-class helpers needed by the conformance tests (no breaking changes for existing consumers). ### Test infrastructure (Tests/Opc.Ua.*) * Test fixture helpers updated to expose what the conformance tests need (`ServerFixture`, `ClientFixture`, `CertificateManagerTests`, `X509TestUtils`, `SubscriptionUnitTests` correctness fixes surfaced by the conformance run). The conformance test project itself (`Tests/Opc.Ua.Conformance.Tests/`) is split out and lives on its own branch / PR — that branch will be rebased on top of this one once this merges.

The app is plug-in based, with a shared Connection panel and address-space tree driving five built-in plug-in tab types: * Subscription — multi-tab live notification scope with six rendering modes (Dots / Bars / Lines / Signal / Histogram / Heatmap) on a custom AnimationCanvas, plus the diagnostic header (seq, missing / republish / dropped, value counters). * Historian — Raw/Modified, Processed-Aggregate, At-Time read modes with UtcDateTimePicker composites, a RangeDialog, inline At-Time edit/save sentinel rows, SharedSizeGroup-resizable result columns, a ScottPlot line chart and CSV export. * Event View — per-tab classic subscription, severity-threshold filter, per-event-type field-selection driven by an in-dialog BrowsePickerDialog event-type chooser, pause / clear / details tree. * Performance — benchmark runner with rate slider, TimeSpan-style [N] [Unit] duration composite, throughput chart, latency histogram with percentile statistics and CSV export. * GDS Push / GDS Management — secondary-session piggyback on the main connection when it is SignAndEncrypt; auto-prompt via a shared picker when the outer session is unsuitable; AdminCredentialsRequired reactive prompt kept. Shared building blocks: * Connection/EndpointCredentialsPicker unifies Discovery → EndpointPickerDialog → CredentialsDialog and is consumed by the Connection panel and both GDS plug-ins. * Connection/DataValueCodec + Views/EncodingPickerDialog + Views/EncodedValueIO provide Binary / XML / JSON encode + decode for DataValue and Variant via the SDK encoders, powering Write Value's Import-from-file, Method Call's per-argument file import, and the address-space Export-value-to-file context menu. * Views/BrowsePickerDialog (lazy tree, NodeClass / ReferenceTypeId filter, async predicate) + Views/FlattenedBrowseDialog (live recursive flat browse with progress) deliver the node-pick fallback used by Historian, Performance and Event-source flows. * Address-space context menu with class-aware entries: Add Item, Add Recursively, Call Method, Write Value, Read history…, Show Events…, Perf…, Export value to file…. Connection plumbing: * Connection/ConnectionService owns the ManagedSession, the certificate validator hook-up (currently auto-accepting untrusted certs while the new ICertificateValidatorEx surface stabilises) and the per-tab subscription adapters. * Connected state surfaces a "Change ▾" flyout with Disconnect, Change User (credentials-only Session.UpdateSessionAsync) and Reconnect (Session.ReconnectAsync). * MainViewModel.IsAddressSpaceVisible mirrors the View menu toggle so plug-ins can short-circuit when the live tree is visible and a suitable node is already selected. * MainViewModel.AddPluginAsync(kind, seedEventSource?, seedPickTarget?) lets the address-space context-menu shortcuts create a new tab pre-bound to the right-clicked node (Historian target, EventView source via EventViewPlugin.SeedSourceAsync, or Performance PickTarget invocation). Build hygiene: * Nullable reference types enforced project-wide (nullable). * Every analyzer bucket cleared; CA2007 swept (await-using sites rewritten to the MS-doc-recommended block form). * UTF-8 mojibake cleaned across files that had been round-tripped through CP-1252. * dotnet build -c Release -f net10.0 clean (0 / 0). * dotnet format --verify-no-changes exit 0. Also moves the upstream "Applications/McpServer" naming to the "Applications/Opc.Ua.Mcp" folder UaLens already uses, so the project file, sign lists, build glob, agent-instruction note, the McpServer docs and the README all reference a single canonical path.
