Copilot	e78c648295	Images CI: publish samples once natively and stop compiling under QEMU (#4679 ) # Description Images CI took 45–100 min per image. The arm64 half of every `linux/amd64,linux/arm64` build ran `dotnet restore` and `dotnet publish` in an arm64 SDK container under QEMU. For `refserver`, publish took 8 min natively for amd64 and 92 min emulated for arm64. On top of that, every one of the 10 matrix legs recompiled the whole stack. The output is framework-dependent portable IL, so the compile is now done once, natively. The image legs only copy files onto the per-platform runtime base image. ### Dockerfiles (all 10) - SDK stage runs on the build platform. The `build` stage is pinned to `--platform=$BUILDPLATFORM`. `-p:UseAppHost=false` keeps an x64 app host out of the arm64 image. - New `prebuilt` stage. It is chosen with a global `ARG PUBLISH_SOURCE`, which defaults to `build`. Local `docker build` and the `docker-compose` files are unchanged. ```dockerfile FROM scratch AS prebuilt ARG PUBLISH_DIR=artifacts/docker/publish COPY ${PUBLISH_DIR}/ /app/publish/ FROM ${PUBLISH_SOURCE} AS publish ``` - Pump: final-stage `RUN`s moved to a native stage. The `sed` on `openssl.cnf` and the `mkdir`/`chown`/`chmod` steps now run in a `$BUILDPLATFORM` `layout` stage. The final stage copies `/layout/` to `/`, so `/app` and `/diag` keep the `$APP_UID:0` owner and `g=u` mode they had before. `openssl.cnf` therefore comes from the build-platform base image. It is a plain config file, so it is expected to match between architectures. ### `docker-image.yml` - Single image list. The image list lives once, in `env.IMAGES` (image, project, Dockerfile). `discover` emits it as the matrix. - New `publish-samples` job. It runs `dotnet publish` for each sample sequentially, so shared libraries compile once. It uses the same options and NBGV version properties as the Dockerfiles and uploads the output as the `docker-publish` artifact. - `build-and-push-image` legs. Each leg: - downloads the artifact; - builds with `PUBLISH_SOURCE=prebuilt` and `PUBLISH_DIR=artifacts/docker/publish/<image>`; - no longer uses `setup-qemu-action`; - is named `build-and-push-image (<image>)`. - `images summary`. It now also fails when `publish-samples` fails. ### Docs - `ContainerReferenceServer.md` describes the publish-once / copy-only flow and the build arguments. - `DeveloperGuide.md` mentions the `publish-samples` job in the Images CI section. Expected: one native publish of about 7 min, then 10 parallel copy-and-push legs of a few minutes each. Not yet confirmed on CI: the sandbox could not pull MCR base images, so the prebuilt multi-platform builds were checked against a Debian-based stand-in base, and the build-from-source path was not built. ## Related Issues ## 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. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: romanett <7413710+romanett@users.noreply.github.com>	2026-10-06 14:21:44 +02:00

Images CI: publish samples once natively and stop compiling under QEMU (#4679 )

# Description

Images CI took 45–100 min per image. The arm64 half of every
`linux/amd64,linux/arm64` build ran `dotnet restore` and `dotnet
publish` in an arm64 SDK container under QEMU. For `refserver`, publish
took 8 min natively for amd64 and 92 min emulated for arm64. On top of
that, every one of the 10 matrix legs recompiled the whole stack.

The output is framework-dependent portable IL, so the compile is now
done once, natively. The image legs only copy files onto the
per-platform runtime base image.

### Dockerfiles (all 10)
- **SDK stage runs on the build platform.** The `build` stage is pinned
to `--platform=$BUILDPLATFORM`. `-p:UseAppHost=false` keeps an x64 app
host out of the arm64 image.
- **New `prebuilt` stage.** It is chosen with a global `ARG
PUBLISH_SOURCE`, which defaults to `build`. Local `docker build` and the
`docker-compose` files are unchanged.
  ```dockerfile
  FROM scratch AS prebuilt
  ARG PUBLISH_DIR=artifacts/docker/publish
  COPY ${PUBLISH_DIR}/ /app/publish/

  FROM ${PUBLISH_SOURCE} AS publish
  ```
- **Pump: final-stage `RUN`s moved to a native stage.** The `sed` on
`openssl.cnf` and the `mkdir`/`chown`/`chmod` steps now run in a
`$BUILDPLATFORM` `layout` stage. The final stage copies `/layout/` to
`/`, so `/app` and `/diag` keep the `$APP_UID:0` owner and `g=u` mode
they had before. `openssl.cnf` therefore comes from the build-platform
base image. It is a plain config file, so it is expected to match
between architectures.

### `docker-image.yml`
- **Single image list.** The image list lives once, in `env.IMAGES`
(image, project, Dockerfile). `discover` emits it as the matrix.
- **New `publish-samples` job.** It runs `dotnet publish` for each
sample sequentially, so shared libraries compile once. It uses the same
options and NBGV version properties as the Dockerfiles and uploads the
output as the `docker-publish` artifact.
- **`build-and-push-image` legs.** Each leg:
  - downloads the artifact;
- builds with `PUBLISH_SOURCE=prebuilt` and
`PUBLISH_DIR=artifacts/docker/publish/<image>`;
  - no longer uses `setup-qemu-action`;
  - is named `build-and-push-image (<image>)`.
- **`images summary`.** It now also fails when `publish-samples` fails.

### Docs
- `ContainerReferenceServer.md` describes the publish-once / copy-only
flow and the build arguments.
- `DeveloperGuide.md` mentions the `publish-samples` job in the Images
CI section.

Expected: one native publish of about 7 min, then 10 parallel
copy-and-push legs of a few minutes each. Not yet confirmed on CI: the
sandbox could not pull MCR base images, so the prebuilt multi-platform
builds were checked against a Debian-based stand-in base, and the
build-from-source path was not built.

Add a documentation learning path and fix issues found while verifying it (#4555 )

## Summary

### Documentation
- Stage the documentation index as a learning path: a first application,
independent client, server, and PubSub paths, then data and services,
companion models, production, advanced integration, and draft or
experimental capabilities.
- Add Getting started (repository samples or NuGet packages), OPC UA
concepts, Your first information model, and a production readiness
checklist.
- Add Native AOT application publishing, a first PubSub publisher and
subscriber exchange, and the UDP transport options.
- Add or expand contents navigation throughout `docs/`, and keep
contributor documentation separate.
- Correct outdated SDK examples and capability guidance, consolidate
repeated explanations into canonical guides, and repair local links and
heading structure.
- Rewrite What's New in 2.0 as a concise feature overview with short
linked details; keep migration instructions in the Migration Guide.
- Expand the feature catalogue with specification IDs, GDS, LDS, the OPC
10000-21 onboarding registrar, ISA-95, xRegistry, OpenUSD, and
sample-local models; distinguish draft status, explain crypto
pluggability, and bring performance guidance forward.
- Address review feedback on wording, active monitored items during
shadow reload, and the `Samples.md` filename and references.
- Regenerate the `opcua-v20-migration` plugin's bundled copy of the
migration guides so it matches the edited `docs/migrate/2.0.x` guides.
- Merge the latest `master`, preserving upstream resource-isolation
guidance within the task-based documentation index.
- Retain deferred Lingity findings where appropriate; this PR does not
claim that every document meets the Lingity score thresholds.

### Fixes found while verifying the guides
Each fix has regression tests that fail without it.
- **Client:** V2 subscriptions compared their lifetime with the
operation timeout instead of the session timeout, and logged a spurious
warning. `ISubscriptionEngineContext`, which is new in 2.0, gains a
`SessionTimeout` property; implementations must add it.
- **PubSub:** a subscriber now registers the `DataSetMetaData`
configured on its readers (OPC 10000-14 6.2.9.4), and the UADP decoder
decodes DataSetMessages that carry no ConfigurationVersion. Before, a
secured subscriber of the reference sample received no DataSets.
- **Source generator:** a ModelDesign method that declares its arguments
inline, without a method type, produced code that did not compile; it
now uses `MethodState`. The generated code of existing models is
unchanged.
- **MinimalClient sample:** waits for its first data-change notification
before it disconnects.

### Known issues, not addressed here
- UDP multicast: the publisher does not send on the interface that the
subscriber joins, and `MulticastLoopback` defaults to false. The PubSub
guide uses unicast for the exchange on one computer.
- The UDP metadata announcement is sent unsecured on secured writer
groups; a secured subscriber drops it with a warning.
- A server does not start in globalization-invariant mode, because
`ResourceManager` creates `CultureInfo("en-US")`. The Native AOT guide
cautions against the mode.

## Validation
- `git diff --check` and
`./.azurepipelines/validate-migration-plugin.ps1` (15 bundled migration
docs validated, plugin manifests synchronized).
- Local Markdown links, anchors, file-link casing, and contents lists
checked across all 87 documents under `docs/`. The index links every
top-level guide and every target of the previous index.
- Both Getting started routes, Your first information model, the PubSub
exchange, and the Native AOT publish of the Getting started client and
server were run as documented. The NuGet route and the tutorial use the
public `2.0.0-preview.5` packages.
- The changed libraries build for all target frameworks in Release
without warnings.
- Tests on .NET 10: Opc.Ua.SourceGeneration.Tests 199 passed;
Opc.Ua.SourceGeneration.Core.Tests 3,977 passed, 8 skipped;
Opc.Ua.Server.Tests `Fluent` category 621 passed; Opc.Ua.Client.Tests
subscription-engine tests 70 passed; Opc.Ua.PubSub.Tests 1,374 passed, 2
skipped; PubSub fuzz replay 145 passed. The new and affected tests also
pass on .NET Framework 4.8.
- Earlier merge validation: 174 resource-isolation tests passed on .NET
10.
- The full solution suite was not run locally.

Review and validation artifacts are maintained outside the repository.

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
