With many event monitored items on one notifier (750 on the Server object in the `events` harness scenario), a single `MonitoredNode2` consumer thread delivers every event to every item and is 100 % busy, which caps the server at ~770 events/s. This PR makes the per-item work cheaper. There are no public API or wire changes. Each commit stands alone: 1. **Server: dequeue events in O(1).** `EventMonitoredItemQueue.Dequeue` used `List.RemoveAt(0)`, which shifted every queued event. It now advances a head index, compacts the list once the dequeued slots are half of it, and clears it when it runs empty. Discard oldest/newest, the `SetQueueSize` truncation and the newest-1000 duplicate range are unchanged. The mirroring redundancy queue snapshots only the queued range. 2. **Server: reuse the event filter context of a monitored item.** `QueueEvent` created a `FilterContext` per event and item. The item now keeps it until the session replaces its `PreferredLocales`. `GetEventFields` writes into a `Variant[]` instead of a `List` that was then copied, and translates with the context's locales instead of looking up the session per LocalizedText field. 3. **Server: check event duplicates against an index of the newest entries.** `IsEventContainedInQueue` loaded the handle of up to 1000 queued entries per item and event. A reference-keyed count of the event instances in the newest 1000 entries, kept current by `Enqueue`/`Dequeue`/`SetQueueSize`, makes it one lookup. The checked range is the same, and wrapped filtered-retain handles count as their instance. If a derived queue changes `m_events` directly, the index is rebuilt. 4. **Core: evaluate an empty content filter without an evaluator.** `ContentFilter.Evaluate` created a `FilterEvaluator` and, through the telemetry context, a new logger for every evaluation, also for the empty where clause of most event filters (~16 % of the scenario's allocated bytes). An empty filter now passes directly, and the evaluator creates its logger only to log a failure. 5. **Core: give the fields of an initialized event a source timestamp.** `BaseEventState.Initialize` created its field variables without a timestamp, so `BaseVariableState.ReadValueAttribute` called `DateTimeUtc.Now` on every read of every field for every monitored item. The fields now carry the event time (`ReceiveTime` its own value). The read path is unchanged, so no `ReadChildAttribute`/`ReadValueAttribute` override is bypassed. ## Measurements `perf/ServerLoadHarness run --scenario events --sessions 50 --subs 15 --pub 100 --security encrypt --event-rate 0 --duration 15 --warmup 8`, with `DOTNET_gcServer=1`, `SERVER_DOTNET_gcServer=1` and `SERVER_DOTNET_TC_QuickJitForLoops=0`, `SERVER_DOTNET_TC_OnStackReplacement=0`. Each build is stacked on the previous one; values are the mean of 2 alternating rounds. Runs where processes outside the harness used more than 1.5 cores were repeated. | build | generated events/s | event→notify p50 | KB / generated event | ms CPU / generated event | |---|---|---|---|---| | master | 768 | 69.8 ms | 567 | 2.97 | | + O(1) dequeue | 791 | 68.4 ms | 566 | 2.78 | | + filter context reuse | 818 | 68.8 ms | 354 | 2.75 | | + duplicate index | 854 | 63.7 ms | 356 | 2.96 | | + empty where clause | 891 | 63.7 ms | 273 | 2.77 | | + event field timestamps | **1001** | **61.3 ms** | **272** | **2.66** | - **`--event-rate 500` (below capacity):** 3.34 → 3.03 ms CPU and 590 → 294 KB per generated event. Latency is unchanged (bound by the publishing interval). - **Default JIT, 40 s warm-up:** 804 → 1063 events/s, 568 → 268 KB, 2.69 → 2.37 ms. - **CPU traces:** the consumer thread's `ReadValueAttribute` self share drops from 24 % to 6 % of the samples and `QueueEvent` self from 14 % to 5 %. The thread is still the bottleneck, now in the generic read chain (`GetAttributeValue` → `ReadChildAttribute` → `FindChild`). The next step would be to evaluate each event once per distinct filter rather than per item, which is out of scope here. ## Notes for reviewers - `EventMonitoredItemQueue.m_events` keeps its protected `List<EventFieldList>` type, but dequeued slots now stay null at the front until compaction. The queued events are the last `ItemsInQueue` entries. Nothing in the repository reads the field outside the class except the mirroring queue, which uses the new internal `CopyQueuedEvents()`. - Event field variables created by `Initialize` now report the event time as `SourceTimestamp` instead of the time of the read. ## Related Issues - No issue.

Marc Schier	15d0ce7bd5	Implement OPC UA Part 10 Programs (#4789) ... # Description Implement OPC UA Part 10 Programs across `Opc.Ua.Core`/`Core.Types`, `Opc.Ua.Server`, and `Opc.Ua.Client`, reusing the existing state-machine, source-generation, node-management, auditing, and streaming-subscription infrastructure. - Add asynchronous provider-backed execution, standard controls, internal/autonomous transitions, generation checks, and nested-state activation/resumption. - Add checked creation/adoption, vendor Create adapters, deletion, recycling and instance limits, auto-delete, DI, and direct-construction paths. - Maintain ProgramDiagnostic2 and retained final results; publish captured intermediate results and concrete transition/audit events with access controls. - Add generated SDK models/proxies, typed client discovery and reads, event streams, and subscribe-before-call readiness handling. - Add unit, connected client/server, generated Annex A-style model, and NativeAOT coverage. Document usage and migration in `docs/Programs.md` and related guides. ### Compatibility and design decisions The linked Part 10 document is v1.05.00; namespace-zero definitions remain aligned with 1.05.07. Documentation distinguishes normative requirements from conflicting specification text and SDK conventions. - Correct state numbers to Halted=11, Ready=12, Running=13, Suspended=14. Generated subtypes retain inherited namespace-zero state/transition identifiers. - Managed Reset is Halted-to-Ready only. Preserve the existing low-level Reset-from-Suspended behavior for compatibility. - Preserve UInt32 limit types; use `UInt32.MaxValue` as a documented SDK unlimited convention. RecycleCount overflow reports BadOutOfRange without stopping unlimited execution. - In-memory default with injectable providers. Durable recovery, distributed execution/failover, and a production Annex A download engine are excluded. ## Checklist _Put an `x` in the boxes that apply.

romanettandClaude Opus 5.5	9b034f8291	Enable nullable reference types centrally; migrate all unset and annotations-only projects (#4700) ... # Description Nullable reference types are now enabled once, in `common.props`, and every project in the repository builds warning-clean with them. **Configuration** - `<Nullable>enable</Nullable>` lives in `common.props`. All per-project `<Nullable>` settings are removed: 178 project files (enable, annotations, and the `disable` in the three Aot test projects). - 419 per-file `#nullable enable`/`restore` directives and the 4 `#nullable disable` directives are removed. - Kept on purpose: - The 5 `<auto-generated>` schema files (`UANodeSet.cs`, `UA Type Dictionary.cs`, `OPCBinarySchema.cs`, `SecuredApplication.cs`, `PInvokeHelper.cs`) keep `#nullable enable`. The compiler ignores the project setting in generated code, so the directive is required there. - `tests/Opc.Ua.Interop.LegacyPeer` keeps `disable`. It builds against the 1.5.378 packages and does not import the repository props. - `docs/DeveloperGuide.md` and `.github/copilot-instructions.md` now describe the central setting. **Migration** (the 43 unset and 13 annotations-only projects, roughly 10k diagnostics) - **Production code: annotated at the declarations.** Covers `tools/Opc.Ua.SourceGeneration.Core`, `src/Opc.Ua.Lds.Server` and the LDS sample. - Members, parameters and returns are nullable where null actually flows. - Null-check helpers carry `[NotNullWhen]` (`IsNull`, `IsValidXmlName`, `IsMethodTypeDesign`). - `CoreUtils.Format`, `Utils.Format`, `ITemplateWriter.WriteLine` take `params object?[]`. `Template.AddReplacement` takes `string?` (rendering already skips null replacements). - `IRegisteredServerStore.RegisterAsync` returns `Task<RegistrationEntry?>`: it returns null when a registration is removed. - Dereferences backed by an invariant (for example, the validated model) use `!`, so runtime behaviour is unchanged. - **Behavioural changes in production code** (small, deliberate): - `NodeSetToModelDesign` throws `InvalidOperationException` when the file is not a NodeSet. Before, it threw a NullReferenceException on the next line. - `ModelDesignValidator` starts its lookup tables empty instead of null. A redundant `if (m_nodes == null) return;` guard is gone. - **Test code: minimal annotations.** - `?` on values that can be null, `!` where the test asserts non-null. - `= null!` for fixture members assigned in SetUp. - `TryGetStructure<T>(out T? x)` where the inferred `T?` broke the `IEncodeable` constraint. - A few redundant `== null` checks on structs (`NodeId`, `ArrayOf<T>`) folded into the adjacent `IsNull`/`Count` checks. **Notes for reviewers** - The diff is large (~1,500 files) but almost entirely mechanical: `?`, `!` and directive removal. The non-annotation changes are listed above. - Known follow-up, not done here: `IModelDesign.Namespaces/TargetNamespace/NamespaceUris` stay non-nullable even though the validator returns null before it loads a dictionary. Making them nullable would ripple through every generator call site. ## Related Issues - Fixes #4439 ## Checklist - [ ] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [ ] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [ ] I have addressed **all** PR feedback received. The "no new warnings" box covers net10.0 and net48: full non-incremental builds of `UA.slnx`, `tools/SourceGeneration.slnx`, `tools/MigrationAnalyzer.slnx` and the Aot test projects finished with 0 warnings and 0 errors under the repository's warnings-as-errors settings. net9.0 and net8.0 also had no nullable diagnostics, but they were not rebuilt after the final fixes. Tests have not been run locally yet. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-08 08:48:13 +02:00
Cristi PogaceanandCopilot Autofix powered by AI	9b8a3b1188	Preserve node initialization and copied child ownership (#4544) ... # Description Preserve populated derived node children through optional initialization and give copied children independent ownership by their copied parent. - Track initialization from a source in `NodeState` and guard generated optional-default recreation without removing the optional initialization hook. - Reuse `CloneChild` for dynamic children, generated typed children, and method argument properties. Preserve the clone root's existing external parent. - Add cross-model initialization/copy regressions, method-argument and nested-child ownership tests, and inherited alarm-subtree checks. This PR contains only the six files for this fix group. Certificate-store, runtime-type-loader, publish-queue and transport-exception fixes are separate work. ## Related Issues Fixes #4525. Fixes #4526. ## Validation Fresh focused Release/net10.0 checks on the final base: | Fixture | Passed | Failed | Skipped | | --- | ---: | ---: | ---: | | CrossModelInstanceTypeDefinitionGeneratorTests | 9 | 0 | 0 | | Types NodeStateTests | 227 | 0 | 0 | | Core StateTypesTests | 13 | 0 | 0 | All three test commands exited 0. `git diff --check` and the changed-file diagnostic check are clean. Regression proof was also executed in the isolated worktree: with the three production changes reversed, six generator cases failed with the missing derived Temperature child while three controls passed; two copy cases failed parent-identity assertions while the external-parent/absent-arguments control passed. The production fix was restored and the focused checks are green. The retained red runs preceded the later upstream synchronization; the affected production paths were unchanged by that synchronization. Windows win-x64 NativeAOT publish and native execution also passed: main 178/178, Historian 2/2, MCP 3/3, no skips, every invocation exit 0. These native runs preceded the final CTT-configuration/notes-only fast-forward; this PR's six files were unchanged. Local validation is intentionally change-scoped for this work, with the full matrix and repository-wide checks left to PR CI. Repository guidance and test assertions/timeouts were not modified. Local commands used a NuGet v2 source override and disabled audit only on the command line; CI feed/audit policy is unchanged. Earlier broad attempts are not claimed as a completed local gate: an unmodified-base durable restart timeout was reproduced before synchronization (the later durable run passed), and the net48 runner stalled after recording passing client tests. A direct client retry subsequently exited 0, but the full net48 matrix was not completed. Those results are not substituted for the focused evidence above. ## Checklist - [x] I have signed the CLA and read the CONTRIBUTING doc. - [x] I have added regression tests and demonstrated failure without the production fix. - [x] The focused tests pass; no new compiler diagnostics were reported by those builds. - [ ] Coverage and the full net48/net10.0 matrix are verified by PR CI. - [ ] All CI, CodeQL, and review feedback is addressed. --------- Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>	2026-09-25 12:23:49 +00:00
Marc SchierandCopilot	da7412c429	Add native xRegistry events and distinct Resource versions (#4396) ... ## Summary - support the xRegistry 0.6.0 distinct Resource/Version hierarchy: `Registry -> Group -> Resource -> Versions -> Version` - instantiate stable logical Resource nodes separately from exact Version nodes while preserving existing Version NodeIds - delegate logical Resource FileType operations and Version-view metadata to the selected default Version with handle pinning and shared writer reservations - make Resource and Version delete behavior role-stable and use `MetaEpoch` / `Epoch` respectively - use stable Resource SourceNodes, exact Version SourceNodes and the `Server -> Registry -> Group -> Resource -> Version` notifier chain - keep a model-metadata-gated client fallback for 0.5 flat Servers; 0.6 Servers expose no legacy aliases - target `HasWoTProjection` at the real stable logical Resource node - use `AsyncCustomNodeManager` for the registration, fast-path, and federation managers, with awaited lifecycle, node mutations, event delivery, and cleanup - handle startup rollback, reentrant deletion callbacks, undisclosed file handles, and retryable cleanup without blocking unrelated file operations ## Authoritative dependencies - companion specification: OPCF-Members/spec-drafts#32 at `d3399fca025025a73e5a6b599f850a81d985c060` - OPC UA binding: xregistry/spec#568 - xRegistry event semantics: xregistry/spec#563, merged as `66ee31e47fbadff6ab982ae1516f7d9065e46b64` - companion NodeSet SHA-256: `369f5f3f1814b333e4eeb52bfb4b6a730cdff372505a5f91a54c94f0016ac4cf` ## Review feedback - keep the WoT Connectivity information-model designation at `1.1`; draft revisions update the publication date without changing the model version - eliminate all 198 unique CA1861 diagnostics across 54 files and remove seven obsolete project suppressions - fix the analyzer-clean touched-path CA1307 and the hierarchy follow-up CA1846/CA1851 diagnostics without dropping legacy-TFM compatibility - recover the reconcile queue after callback faults/cancellation and continue accepted pending changes - remove migration guidance for the xRegistry managers, which are new in 2.0 ## Compatibility - public WoT Connectivity model designation remains `1.1` - generated event-record ABI, constructors, options, NodeIds, and stored documents remain compatible - the generic xRegistry managers are new in 2.0 and implement `IAsyncNodeManager`; use `IAsyncNodeManagerFactory` and the async lifecycle hooks (see `docs\XRegistry.md`) - persistence schema and document blobs remain compatible unless noted below ## Validation - merge validation at `980422f76` with upstream `e8bec27d5`: 454 targeted WoT/materialization/model/registry cases and all 327 XRegistry cases passed on both net10.0 and net48; all 29 net10 aggregation sample cases passed - feedback regressions at `308e8ba74`: 55 targeted queue and live registry event/projection/lifecycle cases passed on each of net10.0 and net48 - prior CI: all 266 checks passed at `6489a0908`; the unchanged Ubuntu Core certificate-counter test and dependent jobs passed on the one-time retry ([run 34117304035, attempt 2](https://github.com/OPCFoundation/UA-.NETStandard/actions/runs/34117304035/attempts/2)) - `Opc.Ua.XRegistry.Tests` — 327 passed on net10.0 and net48 for migration commit `32c914aaf` - `Opc.Ua.WotCon.Tests` net10.0 — 1348 passed - `Opc.Ua.WotCon.Bindings.Tests` net10.0 — 683 passed - `Opc.Ua.SourceGeneration.Core.Tests` net10.0 — 3807 passed, 8 skipped - `Opc.Ua.SourceGeneration.Tests` net10.0 — 145 passed - `Opc.Ua.SourceGeneration.Stack.Tests` net10.0 — 94 passed - affected XRegistry and WoT client/server projects build successfully - xRegistry NodeSet is byte-identical to the companion artifact - repository-wide CA1861 inventory — 198 unique diagnostics across 54 files reduced to zero - targeted changed-fixture validation — 1,098 passed, 3 skipped, 0 failed - constrained full `UA.slnx` net10.0 Release build — CA1861 = 0 - `Opc.Ua.XRegistry.Client` net472 and netstandard2.1 builds — 0 warnings, 0 errors - independent shared-array safety review — no significant issues - `git diff --check` The final review regressions cover concurrent reconcile/open, synthetic logical handle collisions across default switches, cross-session Close isolation, shared writer reservations, logical FileType property/change propagation, logical Labels delegation, role-fixed deletion, event sources, model-version gating, and stable `HasWoTProjection` targets.
