romanett	d6356766c5	Resolve the open CTT findings: aggregate fixes, de-DE ApplicationName and CTT configuration (#4545) ... # Description Resolves the open items of `plans/ctt-issues.md` (*Needs clarification*, *Open server findings*, *CTT project configuration notes*). Each item was checked against the OPC 10000 spec text. A server change was made only where the server was wrong, and every server change has a regression test. CTT script and oracle defects are filed in Mantis instead. ### Server changes (`Opc.Ua.Server`) - **NumberOfTransitions honours TreatUncertainAsBad.** - Part 13 §5.4.3.24 does not count Bad values. §4.2.1.2 makes Uncertain values "equivalent to Bad" when TreatUncertainAsBad is True, and the aggregate definition doesn't override that. - Uncertain values are therefore no longer counted, and no longer used as the previous value, when the setting is True. The now unused `TimeSlice.NonBadEarlyBound` is removed. - **DurationInStateZero/NonZero status follows the variable's interpolation.** - §5.4.3.2.2: "A region is Uncertain if a region ends in a Bad or Uncertain value and SlopedInterpolation is used." - The calculator always built stepped status regions. So on a sloped variable, the last region stayed Good while TimeAverage2 and Total2 over the same interval were already Uncertain. - The duration value doesn't change. - **AnnotationCount returns `Bad_NoData` and sets Partial.** - Table 68 requires `Bad_NoData` for intervals before the start or after the end of data. §5.3.3.2 requires the Partial bit for incomplete intervals. - `HistorianDispatcher` now derives the start and end of data from the raw history (read with bounds) plus the annotation timestamps. It passes them to a new `CalculateAnnotationCounts` overload; the old overload is unchanged. - Three existing dispatcher tests change their expectations. For example, a node without any data now returns `Bad_NoData` instead of Good zeros. ### Reference server sample and CTT configuration - **`de-DE` ApplicationName.** The server advertises `de-DE` in LocaleIdArray, but FindServers and GetEndpoints always returned the en-US name. The sample now keys the ApplicationName and registers en-US and de-DE translations (Part 4 §5.5.2.2 / §5.5.4.2 localeIds). - **Subscription limit.** `Max Supported Subscriptions` in `samples/UAReferenceServer.ctt.xml` and `MaxSubscriptionCount` in `Ctt.ReferenceServer.Config.xml` go from 100 to 200. Subscription Publish Min 05 `003.js` needs 190 subscriptions. - **Alarm Cycle Time.** The CTT template's Alarm Cycle Time is 30 s. At 60 s it equalled `RequestedSessionTimeout`, so a Limit/Level CU that starts a run finds its session expired (C40). ### Tests only - **AddNodes duplicate BrowseName test:** `AddNodeAsync_DuplicateBrowseNameUnderParent_ReturnsBadBrowseNameDuplicatedAsync` never ran. Its items had no TypeDefinition, so its `Assume` always made it inconclusive. The finding it belongs to (AddNodes after a rename returning `BadNodeIdExists`) was already fixed by #4477. - **RequestHandle echo:** a new test covers the ServiceFault for an oversized argument in a chunked request (already fixed by #4488). - **Value-based status:** a new test covers the aggregate status with TreatUncertainAsBad = false (already fixed by #4503). ### Not changed - **GDS QueryApplications/QueryServers still return records with ServerCapability `NA`.** OPC 10000-12 §6.5.10/§6.5.11 says they "shall not", but the CTT GDS scripts expect those records. Implementing the exclusion turned 40 GDS test cases from pass to error, so it waits for the script fix ([Mantis 11458](https://mantis.opcfoundation.org/view.php?id=11458)). - **Idle SecureChannels are still closed after `ChannelLifetime`.** Keeping them open would be security relevant. The CTT configuration's `ChannelLifetime` of 120000 (#4502) covers the CTT case. ### Mantis issues filed | Id | Issue | | --- | --- | | C51 | [11458](https://mantis.opcfoundation.org/view.php?id=11458) GDS scripts expect NA records in query results | | C52 | [11459](https://mantis.opcfoundation.org/view.php?id=11459) A & C Refresh scripts leak subscriptions on the shared alarm session | | C53 | [11460](https://mantis.opcfoundation.org/view.php?id=11460) `StartThreadPublish.js` defaults misspelled properties | | U2 | [11461](https://mantis.opcfoundation.org/view.php?id=11461) Minimum2 oracle on reverse reads | | U4 | [11462](https://mantis.opcfoundation.org/view.php?id=11462) Part 13 clarification: TreatUncertainAsBad and simple bounds (DeltaBounds) | The A & C `BadSubscriptionIdInvalid` failures (Refresh, Refresh2, Shelving) come from CPU load: with other processes at 100 % CPU, all subscriptions of the CTT alarm session expire within one second. This happens with and without this PR (3 of 3 loaded runs, 0 of 2 idle runs). ### CTT verification CTT 1.05.06, scripts 1.05.513, compared at test-case level against a build of the starting commit: | Group | Before | After | | --- | --- | --- | | Aggregates | 4,562 error messages | 4,186. NumberOfTransitions: 12 test cases go from error to pass. AnnotationCount `005-01.js`/`005-02.js` pass. NumberOfTransitions `003-02.js`/`004-02.js` now fail because of C1 ([Mantis 11420](https://mantis.opcfoundation.org/view.php?id=11420)): they request TreatUncertainAsBad = false, but the harness makes the server use its default of true. | | Discovery | 10 warnings | 0. Find Servers Filter `003.js`/`006.js` and Get Endpoints `002.js` pass. | | Subscription | – | Publish Min 05 `003.js` goes from warning to pass. | | Historical Access, GDS, Node Management | – | no new failures | `plans/ctt-issues.md` is updated: resolved items leave the open sections, and the new Mantis issues are recorded. ## Related Issues - Related to #4479 (CTT configuration notes) - Follows #4502 ## 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. - [ ] 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.

romanett	13f96fd4ba	Raise ChannelLifetime for the CTT reference server and record the full CTT run of the merged CTT PRs (#4502) ... # Description Findings of a full CTT run (23 parts, 3,752 test cases, CTT 1.05.06 / scripts 1.05.513) against the merge of #4477, #4482, #4485 and #4486, which are all on master now, plus the CTT defects filed in Mantis. No server code changes: the PR changes only the CTT configuration of the reference server sample and the `plans/` documentation. ## CTT configuration: raise `ChannelLifetime` to 120 s CTT Security None `007.js` and Security Basic256Sha256 `005.js` failed (also on master): they keep SecureChannels without a Session idle for about 51 s (60 s token, stretched by the CTT's CloseSession delay, C50) and expect the newest one to close with Good. `TcpTransportListener.DetectInactiveChannels` had already closed it after `ChannelLifetime` (30 s) without traffic (`CloseSecureChannel().Result received BadInvalidState`). `samples/Reference/ConsoleReferenceServer/Ctt.ReferenceServer.Config.xml` now sets `ChannelLifetime` to 120000. The default of 30000 and the server's inactivity cleanup are unchanged. An earlier revision of this PR changed the inactivity cleanup instead, keeping idle Session-less channels open until their token expired (Part 4 §5.6.2.1). That change was withdrawn because it lets an unauthenticated client hold a channel for up to the `SecurityTokenLifetime` (one hour by default) instead of 30 s. The difference to Part 4 §5.6.2.1 is recorded as an open server finding in `plans/ctt-issues.md`. Validated on 2026-09-24 with the reverted code and the new configuration (full run, compared with the run of 2026-09-22 at test-case level): - Security None `007.js` passes and Security Basic256Sha256 `005.js` has only the C50 CloseSession delay warnings (both failed with 30 s). - All other parts have the same error signatures as before; the remaining differences are *"Response Timestamp shows a delay"* warnings from a loaded machine (a back-to-back Session Services run with 30 s and 120 s on an idle machine is identical). - A & C Refresh2 `Err_003.js`/`Err_004.js` and Shelving `initialize.js` report `BadSubscriptionIdInvalid` in today's runs with both 30 s and 120 s on the same build, so they are unrelated to the configuration (both passed again in a run on the idle machine with 120 s). ## Mantis 32 CTT defects filed on 2026-09-24 (11420–11454, script issues in *CTT UA Scripts*, native aggregate oracle issues in *CTT UA Binary*); 12 drafts were already covered by existing reports (including GDS issues 11406–11413 by node-opcua and 11102 for the `opc.https`/`opc.wss` endpoint selection); 5 are held back for further investigation. `plans/ctt-issues.md` links every entry. ## CTT documentation (`plans/ctt-issues.md`, `plans/ctt-testing.md`) - `ctt-issues.md` lists every failing CTT test case with a short abstract and its Mantis issue; the details live in Mantis. It keeps the defects not filed yet, the open questions (U1–U4), the open server findings and the CTT project configuration notes, and no longer lists findings the server has fixed. - Notable CTT findings of this run: the aggregate oracle lacks the Part 13 Uncertain status and Calculated bit rules that #4477 implements (C48/C49, 24 test cases); the CloseSession "delay in excess of 600ms" warnings are a CTT client artifact (C50: the server answers in 2–5 ms, the CTT stops the Session's SessionThread between stamping and sending); the CTT's `FindTokenType` rewrites its cached endpoints, so Security User Name Password 2 `015.js` reports duplicate PolicyIds (C36); A & C Comment passes or skips depending on the date (C39). - Open server finding: AddNodes after a child rename returns `BadNodeIdExists` (#4477 × #4486 interaction, not covered by the CTT). - `ctt-testing.md` is a runbook for agents: setup, headless runs, selection generation, reading and comparing results, triage, recipes per conformance group (A & C, Session/Subscription, Monitored Items, security groups with an isolated PKI) and a full partitioned run of every group (about 80 minutes). It points to `ctt-issues.md` for the failures to expect. ## Related Issues - Follow-up to #4477, #4482, #4485, #4486 ## 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. - [ ] 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.

Copilot	d525bc3f28	Bound reconnect cleanup and organize samples by domain (#4276) ... # Description This PR fixes bounded ManagedSession reconnect cleanup and reorganizes the sample applications into domain-focused folders. ## Reconnect cleanup - Bounds reconnect integration cleanup with independent 30-second close and dispose limits. - Sends `CloseSession` through the awaited transport request path during `Session.DisposeAsync`. - Preserves explicit `Session.CloseAsync` behavior that waits for or cancels outstanding publish requests. - Covers the disposal request path with a regression test. ## Sample organization - `samples/OpenUsd`: `GeneratorServer`, `SiteCompositionServer` - `samples/Redundancy`: `RedundantClient`, `RedundantServer`, `RedundantPubSub` - `samples/Isa95`: `MinimalIsa95Server` - `samples/MinimalApi`: `MinimalBoilerServer`, `MinimalCalcServer`, `MinimalClient` - `samples/DI`: `PumpDeviceIntegrationServer` - `samples/Lds`: `ConsoleLdsServer` - `samples/Reference`: `ConsoleReferenceClient`, `ConsoleReferenceServer` - `samples/PubSub`: `ConsoleReferencePubSubClient` `UA.slnx` now exposes the same requested domain groups. Project references, tests, runtime sample probes, CI workflows, Dockerfiles, Compose files, helper scripts, and documentation were updated to the new paths. `samples/Robotics/MinimalRobotServer` remains under `Robotics`. ## Validation - `dotnet build UA.slnx` - 3 Redundancy short-haul sample tests - 70 DI sample tests - 914 OpenUSD tests - 1 WotCon model-materialization test - 137 AOT tests - `docker compose config` for all 6 moved Redundancy Compose files ## Related Issues - Fixes #4273 ## 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. - [x] I built the complete `UA.slnx` solution locally. - [ ] I ran all tests locally against at least .NET Framework and .NET 10. - [ ] 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-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: marcschier <11168470+marcschier@users.noreply.github.com> Co-authored-by: Marc Schier <mschier@microsoft.com> Co-authored-by: Marc Schier <marcschier@users.noreply.github.com> Copilot-Session: a2c2838f-74ae-4997-a1d4-50574d9e0636	2026-08-21 04:35:47 +00:00
