The stack's log messages wrote network addresses (endpoint, discovery and reverse connect URLs, host names, IP addresses, ports), application and user identities, file paths and exception texts as plain parameters. Applications had no reliable way to keep them out of general-purpose logs. This PR replaces the stack's own redaction mechanism with the standard .NET [data classification and redaction](https://learn.microsoft.com/dotnet/core/extensions/data-redaction) packages. Each sensitive `[LoggerMessage]` parameter is classified. The application decides per classification what reaches its logs: erase it, replace it with an HMAC token so entries stay correlatable, or pass it through. ### Taxonomy `Opc.Ua.Redaction.OpcUaDataClassifications` defines the `OpcUa` taxonomy and one attribute per classification: | Classification | Used for | Parameters | |---|---|---| | `[NetworkAddress]` | URLs, host and domain names, IP/MAC addresses, end points, ports | 120 | | `[ApplicationIdentity]` | certificates, subject, issuer, thumbprint, ApplicationUri | 103 | | `[FilePath]` | file, directory and certificate store paths | 67 | | `[SensitiveText]` | exception or remote-supplied text passed as a parameter | 55 | | `[UserIdentity]` | user names, token subjects | 7 | Correlation ids (`ChannelId`, `SessionId`, ...), status codes and NodeIds stay unclassified. ### Pipeline and defaults - Opc.Ua.Core now references `Microsoft.Extensions.Telemetry(.Abstractions)` 10.11.0, so every project above Core uses the `Microsoft.Gen.Logging` generator. Opc.Ua.Client already did, through Http.Resilience. The packages ship net462 and netstandard2.0 builds, so net48 is supported. - **A plain `ILoggerFactory` logs `(null)` in place of classified values.** Classified values are only written by the redaction-aware logger. - The new `ILoggingBuilder.EnableOpcUaRedaction()` turns that logger on. It is `EnableRedaction()` with the discriminator off; otherwise every unredacted value gets `:ParamName` appended. `AddOpcUa().AddLogging(...)` and `DefaultTelemetry.Create(...)` call it, as do the samples, so they log the same information as before until redactors are registered. - `services.AddOpcUa()` alone does not change the host's logging. Generic-host apps call `builder.Logging.EnableOpcUaRedaction()`. This is documented as a behavior-breaking change in `docs/migrate/2.0.x/telemetry.md`. ### Obsolete API `Redact`, `RedactionWrapper<T>`, `IRedactionStrategy`, `RedactionStrategies` and `SimpleRedactionStrategy` are `[Obsolete]`. They still work, but the stack no longer uses them. ### Not classified - The `Exception` passed to a log call. Applications can drop exception messages with `LoggerEnrichmentOptions.IncludeExceptionMessage`. - Exception and `ServiceResult` message texts. - `ServiceResult`/`StatusCode` parameters and logged data values. - The few log calls whose level is decided at run time. - `Opc.Ua.Vision.OpenUsd`, which references only Opc.Ua.Types and cannot see the attributes. ### Generator behavior differences These are visible to log consumers and to tests: - `IFormattable` values such as `NodeId` are stored in the structured state as invariant strings, not as objects. - The generated log state is a thread-local object that is cleared after the call. - Classified values are pooled redactor objects, valid only during the `Log` call. Tests that inspected log state after the fact now capture it during the call. The shared `RecordingLoggerProvider` snapshots classified values. ## Related Issues - Fixes #4857 ## Types of changes - [ ] Bugfix (non-breaking change which fixes an issue) - [x] Enhancement (non-breaking change which adds functionality) - [ ] Test enhancement (non-breaking change to increase test coverage) - [x] Breaking change (fix or feature that would cause existing functionality to not work as expected; plain logger factories drop classified values) - [x] Documentation Update (if none of the other choices apply) ## Checklist - [x] I have read the CONTRIBUTING doc. - [x] I have signed the CLA. - [x] I ran tests locally with my changes, all passed. - [x] I fixed all failing tests in the CI pipelines. - [x] I fixed all introduced issues with CodeQL and LGTM. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added necessary documentation (if appropriate). - [ ] Any dependent changes have been merged and published in downstream modules. ## Further comments New tests: - `LogClassificationCoverageTests` (Tools.Tests) scans all 104 stack assemblies and fails if an address, identity or path parameter of a `[LoggerMessage]` method is unclassified. - `DataClassificationLoggingTests` (Core.Tests) pins erasing and HMAC redaction, pass-through, the plain-factory drop, and both stack defaults. Local results on net10.0: | Suite | Passed | Failed | |---|---|---| | Core.Tests | 6,489 | 0 | | Client.Tests | 3,231 | 0 | | Tools.Tests | 7,210 | 0 | | PubSub.Tests | 1,536 | 0 | | Core.Diagnostics.Tests | 571 | 0 | | Configuration.Tests | 241 | 0 | - **Server.Tests:** the full run predates the final test fixes and had 12 failures. All 12 were in the fixtures fixed afterwards, which now pass: RoleStateBinding (45/45) and the FileDirectory and compatibility-logging fixtures (74/74 in total). The full Core.Tests and Server.Tests runs were not repeated after those fixes. - **Builds:** `UA.slnx` builds with 0 errors for net10.0 and net48, and the whitespace check passes. - **NativeAOT:** not confirmed locally, because the machine has no C++ linker. A trimmed publish of `Opc.Ua.Aot.Tests` reported no trim or AOT warnings from the stack, the new packages or the generated logging code; its only errors come from the TUnit test framework (`FSharp.Core` not found). The `aot-test` CI job has to confirm the native build. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: Marc Schier <marcschier@users.noreply.github.com>	2026-10-21 09:47:07 +00:00
Marc SchierandCopilot	b97fd8d4b5	Fix OPC 10000-21 onboarding interoperability (#4385) ... # Description Fix the four blockers that prevented the OPC 10000-21 onboarding registrar and client from working end to end: - generate every `ModelDesign` target independently, including multiple models in one directory, while preserving stable identifier CSV matching and cross-model dependencies; - ship the generated `Opc.Ua.Onboarding` constants, node states, encodeables, and typed clients from `Opc.Ua.Gds.Common`; - correct the standard `EncodedTicket` datatype to derive from `ByteString`; - align the new 2.0 `OnboardingClient` API with the generated `ArrayOf<ByteString>` / `ArrayOf<StatusCode>` contract; - make `BindToTicketStore` fully asynchronous, cancellation-aware, and assign the declared output slot instead of appending a second output; - add generated-model, client fallback, server binding, and in-process end-to-end regressions. The change also adds `samples/Gds/OnboardingRegistrar`, `samples/Gds/OnboardingClient`, and `run-onboarding-demo.ps1`. The demo loads the generated GDS and Onboarding models, restricts ticket administration to an ephemeral `RegistrarAdmin` user, proves anonymous access is denied, and completes a secure register/unregister round trip. The History CI follow-up rejects negative and non-finite processed-history intervals before provider dispatch and enforces the buffered aggregate output cap while calculator results are flushed. This prevents malformed requests from running until the client timeout, exhausting memory, delaying server teardown, and causing later alarm-event tests to fail. ## Related Issues - Fixes #4378 - Unblocks OPCFoundation/UA-.NETStandard-Samples#819 - Tracks the canonical model correction in OPCFoundation/UA-Nodeset#122 ## Validation - Full `net10.0` test projects: - `Opc.Ua.SourceGeneration.Core.Tests`: 3803 passed, 8 skipped - `Opc.Ua.SourceGeneration.Tests`: 143 passed - `Opc.Ua.Gds.Tests`: 1114 passed, 42 skipped - `Opc.Ua.History.Tests` with the CI coverage settings: 506 passed, 27 skipped - `HistorianDispatcher` tests: 88 passed on `net10.0`. - Invalid processed-history interval regressions passed on `net10.0` and `net48`. - Focused onboarding/source-generation regressions passed on `net48`. - `dotnet build UA.slnx -p:CustomTestTarget=net10.0 --no-restore` succeeded; the reported analyzer warnings are pre-existing in unchanged XRegistry/WoT files. - Packed all three GDS packages and verified the packaged `Opc.Ua.Gds.Common` assembly contains the generated Onboarding model surface. - `pwsh samples/Gds/run-onboarding-demo.ps1` verified anonymous denial and the authenticated secure ticket lifecycle. ## 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. - [x] 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. - [x] I have addressed **all** PR feedback received. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 2d2c52c7-7040-4bd6-98de-aaf82ba7846b	2026-09-02 11:39:19 +02:00
