Why

In recent .NET runs, PublishTestProjectAOTModule is the critical path of the pipeline on every OS:

Job (run 39462191856)	AOT publish	Then waiting on it
ubuntu	12m 22s	RunEngineAotTests 1m 8s → RunEngineTests 7m 30s → Aspire/OTel
macOS	11m 54s	RunEngineAotTests 1m 41s → RunEngineTests 4m 42s
windows	9m 56s	RunEngineTests 5m 59s → RunEngineAotTests 1m 35s

On a busier macOS run (39437393424) the publish took 24m 57s, and the pipeline took 34m. Every other test module had finished minutes before the engine tests could start. The publish is slow because it competes with ~16 concurrent test modules for the runner's CPUs. The engine tests were deliberately held behind it so that they didn't slow it down further. PublishNugetTesterAOTModule (three more native AOT publishes, 3–8 min) competes for the same CPUs.

What

• New Aot pipeline category on PublishTestProjectAOTModule, RunEngineAotTestsModule and PublishNugetTesterAOTModule.
• New aot.yml workflow (ubuntu/windows/macos) that runs --categories Aot Packaging. It versions with GitVersion, then builds only the libraries (for packing), TUnit.Engine.Tests (which builds the test projects it launches) and the pipeline. No full solution build.
• The dotnet.yml matrix ignores Aot. RunEngineTestsModule no longer waits for the publish, and RunEngineAotTestsModule no longer waits for the other test modules.
• PublishNugetTesterAOTModule no longer runs in the Windows NuGet job, which only selects Packaging NuGetPackageTests; aot.yml covers Windows. Its dependency on TestNugetPackageModule (shared NugetTester bin/obj) is now optional, so local full runs still order them.
• UploadToNuGetModule no longer depends on RunEngineAotTestsModule. Instead, before pushing, it waits for an aot.yml run for the commit to succeed (actions: read).

Expected effect: the matrix pipeline should end around when its last non-AOT module finishes, roughly 8–12 minutes sooner per OS.

Trade-offs

• Three more jobs per push, one of them on macOS, the scarcest runner type.
• aot.yml packs on each OS as well, so packaging now happens in one more place.
• If branch protection requires specific checks, add the AOT (…) checks.

Also fixed

• BuiltInExpectationMessageTests.Built_In_Declarations_Render_Expectations failed the Windows leg since Fix TUnit0014 on interface implementations, Aspire exit-code culture and [AssertionFrom] expectation messages #7135: net472 parses the [AssertionFrom] sources without the NET symbols, so only 95 expectations render against a > 100 guard. The guard is now > 50.
• Release publishing now waits for the aot.yml run on the same commit to pass (UploadToNuGetModule.WaitForAotWorkflowAsync), instead of relying on a manual check.

Summary by CodeRabbit

• Chores
  • Added automated native AOT build, test, and packaging workflows for pull requests, main-branch changes, and manual runs across Windows, macOS, and Linux.
  • Improved pipeline coordination so package publishing waits for successful AOT validation before proceeding.
  • Added clearer handling for workflow timeouts and missing build metadata.
  • Enhanced failure diagnostics with automatic collection of logs and hang reports.
  • Updated test scheduling to separate AOT validation from standard engine and package testing.

📝 Walkthrough

The PR adds a dedicated cross-platform workflow for AOT and packaging tasks. It updates pipeline category routing and standard workflow filters. NuGet publication now waits for a successful AOT workflow run for the current commit.

Changes: AOT Pipeline

Layer / File(s)	Summary
Define and route AOT pipeline work tools/TUnit.Pipeline/PipelineCategories.cs, tools/TUnit.Pipeline/Modules/*, .github/workflows/dotnet.yml	The new Aot category is applied to AOT modules. Related test-module dependencies are removed. The standard workflow excludes AOT work from its matrix jobs.
Run AOT work across platforms .github/workflows/aot.yml	The workflow builds required projects and runs the Aot and Packaging categories on Ubuntu, Windows, and macOS. It uploads diagnostic logs and hang dumps after each job.
Gate NuGet publication on AOT completion .github/workflows/dotnet.yml, tools/TUnit.Pipeline/Modules/UploadToNuGetModule.cs	The publishing module validates repository and commit metadata, then polls aot.yml runs for that commit. It proceeds after a successful run and fails if all discovered runs complete without success or the wait times out.

Review

Moving the AOT publish and AOT-mode engine tests into their own aot.yml workflow is a sound way to take the critical path off the main matrix. I only read the diff and grepped for other references to the two AOT modules; I didn't run any of the workflows.

Concerns

1. Release safety gap. UploadToNuGetModule no longer depends on RunEngineAotTestsModule, and the replacement is only a code comment saying to check the AOT workflow by hand. A release can now be published with a broken AOT build. Ideas:

   • Have the publish job in dotnet.yml depend on a workflow_run or reusable-workflow call (uses: ./.github/workflows/aot.yml with workflow_call) so the AOT result gates publishing.
   • Failing that, add a pre-publish step that queries the AOT check status for github.sha via gh api and fails if it isn't green.
     A comment is easy to forget.

2. Branch protection. Required checks that match the old matrix names are unaffected, but the new AOT (…) checks are not required unless someone adds them. The PR description says so. Until they are required, AOT regressions can merge.

3. Duplicate setup drift. aot.yml copies the Dev Drive, long-path and setup steps from dotnet.yml. A composite action for the shared setup would keep the two from diverging.

4. Trigger parity. aot.yml runs on every PR and push, including docs-only changes. If dotnet.yml uses path filters, mirror them here to save macOS runner minutes.

5. Build step. The build step calls dotnet build without --no-restore, and the Version: 1.0.0 env workaround is easy to miss. Both are fine, but the pipeline invokes dotnet run --no-build, so the pipeline project must be built in Release, which it is. This looks correct.

Positives: the ignore-categories expression is correct for both OS cases. The PublishNugetTesterAOTModule optional dependency is cleanly removed. The category constant is documented.

Overall this looks good, with the release gating (point 1) the one thing I'd address before merging.

Dispositions for the github-actions review (19:31), as of dad5bce:

1. Release safety gap: fixed in dad5bce. UploadToNuGetModule waits for an aot.yml run on the same SHA to pass before it pushes anything, and fails when none passed or none finishes within 60 minutes. The Codex and CodeRabbit threads on the same point are resolved.
2. Branch protection: this is a repository setting, not something the PR can change. The AOT (ubuntu-latest), AOT (windows-latest) and AOT (macos-latest) checks need adding as required checks once this merges.
3. Duplicate setup drift: not changing this. aot.yml copies three short steps (Dev Drive, setup-dotnet, long paths). A composite action for them would add indirection for little gain, and the steps already differ between workflows (the AOT job skips the disk cleanup and full solution build).
4. Trigger parity: no change needed. dotnet.yml has no path filters (pull_request: branches: [main] only), so aot.yml already matches it.
5. Build step: no action. The review confirms it's correct.

Greptile had no findings.

Review

Moving the AOT publish and the AOT-mode engine tests into their own aot.yml workflow is a sound way to shorten the critical path. The Aot category, the ignore-categories wiring in dotnet.yml and the dropped DependsOn attributes look consistent. I reviewed the diff only and did not run anything.

Concerns

1. Release gate race (UploadToNuGetModule.WaitForAotWorkflowAsync). On a push to main, dotnet.yml and aot.yml start at about the same time. If the poll runs before GitHub has registered the aot.yml run, for example on a manual dispatch right after a push, the zero-runs case throws 'no run exists'. Retry a few times when no runs exist before failing, or document the ordering.

2. Gate semantics. Any(success) passes if any run for the SHA succeeded. That is fine for re-runs. It also accepts a pull_request run with the same head SHA, which is not the merge commit. Filter the WorkflowRunsRequest by Event (push or workflow_dispatch) so the gate reflects the commit being released.

3. Branch protection. The new AOT checks are not required, so PRs can merge with a broken AOT mode and are caught only at release time. I'd confirm the checks are added as required.

4. Cleaner alternative. Polling the Actions API from inside the publish module couples the release to another workflow's timing. It also holds a runner for up to 60 minutes and needs the extra actions: read permission. Consider calling aot.yml via workflow_call as a needs: job, so GitHub enforces the ordering.

5. Minor. Please confirm that PublishTestProjectAOTModule and RunEngineAotTestsModule have no other implicit dependencies, such as version generation or a local NuGet copy, that exist only in the full pipeline.

Overall this is a good change. I'd address items 1 and 2 before merging.

[github-actions]

Review

Good change overall. Moving the native AOT publishes into their own aot.yml workflow takes them off the shared CPUs, and the Aot category is wired consistently. The release gate in UploadToNuGetModule is a sensible way to keep AOT failures from shipping. I read the diff but did not run the workflow or the pipeline.

Concerns

1. Release race on aot.yml start-up. WaitForAotWorkflowAsync throws immediately if ListByWorkflow returns zero runs for the SHA. Both workflows trigger on the same push. The dotnet.yml pipeline takes a long time to reach UploadToNuGetModule, so a missing run is unlikely in practice. A run that is queued or delayed, or an API that is slow to list it, would still abort a release with a misleading "no run exists" error. I'd treat an empty result as "keep polling" for a short grace period (about 2–5 minutes) before failing.

2. Pagination and a non-obvious success rule. Only the first page of runs is read (30 by default). That is fine today. Passing PerPage explicitly, or filtering with Event = "push", would make the intent clear. Without the event filter, a workflow_dispatch run on the same SHA could satisfy the gate. That may be intended, but a comment saying so would help.

3. GITHUB_SHA versus the packed commit. The check relies on GITHUB_SHA matching the commit aot.yml ran on. For push events it does. For a workflow_dispatch publish from dotnet.yml, a dispatched run on a ref with no matching aot.yml run will fail closed. That is safe, but it is worth documenting in the module comment.

4. Duplicate packing and build cost. aot.yml repacks on three OSes and builds via a generated libraries.slnf. The grep-over-slnx step is brittle (it depends on the src/ path convention and on content/ being excluded). Consider a checked-in .slnf, or a pipeline target that builds its own inputs, so that adding a library project can't silently drop it from the AOT build.

5. Branch protection. The PR notes that the AOT (…) checks must be added to required checks manually. Without that, a red AOT job no longer blocks merging, because it is no longer part of the matrix. The release gate covers publishing, but it doesn't cover merging.

Nothing blocking; item 1 is the one I'd fix before merge.

[github-actions]

Review

The change is sound. Moving the AOT publishes onto their own runners removes the CPU contention that made them the critical path. Dropping the artificial DependsOn chains is the right fix, and the Optional = true handling on TestNugetPackageModule keeps local ordering intact. The > 50 guard fix is reasonable and the comment explains it.

Points worth considering:

1. Release gate race and timing. UploadToNuGetModule now polls the aot.yml run for the commit. That works for push-to-main. For workflow_dispatch publishes, aot.yml has to have been dispatched on the same SHA, otherwise the module fails with 'no run exists'. The message says this, which is good. It is worth documenting in the release docs too. A better long-term shape would be a workflow_run/needs-style dependency, or a reusable workflow called from dotnet.yml, so the publish job depends on the AOT job natively. That would remove the polling code, the actions: read permission and the 60-minute busy-wait that holds a runner.

2. Re-runs and cancellation. concurrency with cancel-in-progress is keyed on run_id for pushes, so pushes are never cancelled. If a run is cancelled or failed and then re-run, the poll sees the same run flip back to in-progress. That is handled. A failed run followed by a green re-run is also handled, because it checks Any(success). However, a stale success from an earlier attempt could mask a later failure. This is an edge case and probably acceptable.

3. Pagination. ListByWorkflow returns the first page (30 runs). That is fine when filtered by HeadSha. Adding Event/Branch filters would make the gate stricter, so a PR run on the same SHA cannot satisfy it.

4. Null-forgiving on Repository!. Fail with a clear message, as you do for the SHA, instead of a NullReferenceException.

5. Branch protection. As the description notes, the new AOT (…) checks must be made required, or AOT regressions will no longer block PR merges. Please do this before or at merge.

6. Build step duplication. The libraries.slnf generation via grep on the slnx is fragile (format-dependent). Consider a checked-in .slnf so the filter is reviewable and does not silently drift.

No blocking issues. Nice CI improvement.

[github-actions]

Review

Good change overall: moving the native AOT publish and AOT-mode engine tests into their own aot.yml workflow takes them off the critical path, and the category wiring is clean. The > 50 guard fix is reasonable.

Concerns, mainly about the release gate in UploadToNuGetModule.WaitForAotWorkflowAsync:

1. Module timeout vs. the 60-minute wait. The wait loop allows up to 60 minutes, but UploadToNuGetModule.Configure() sets no WithTimeout. If ModularPipelines' default module timeout (about 30 minutes, which the AOT publish module already had to override) applies, the module will be killed before your own TimeoutException fires, and the failure message will be unclear. Set .WithTimeout above AotWorkflowTimeout explicitly.

2. Startup race. If dotnet.yml reaches the upload step before GitHub has created the aot.yml run for the SHA, the Count == 0 branch throws immediately. This is unlikely, since the AOT publish takes 10+ minutes and the matrix takes longer, but a short grace period (retry on an empty list for the first ~2 minutes) would remove the flake. It would be cheap insurance for a release step.

3. What counts as a pass. Any successful run for the SHA is accepted, including a workflow_dispatch or a stale run. That is probably fine. ListByWorkflow is also paginated, so it only inspects the first page, which is fine for one SHA. Consider filtering on Event == push for stricter semantics.

4. Branch protection. As noted in the description, the new AOT (…) checks must be added to the required checks, or PRs can merge without AOT coverage. Please confirm that is done or tracked.

5. Duplication. The aot.yml build and version-export steps largely copy dotnet.yml. A composite action would stop the two drifting, which matters because the libraries.slnf grep filter is fragile when project layout changes. This could be a follow-up.

None of these are blockers except possibly (1), which is worth verifying.

Dispositions for the github-actions reviews at 20:12, 20:13 and 20:21 and the CodeRabbit outside-diff comment (20:22), as of 00bb8b0. Main is merged in 38e91fb; the only conflict was the expectation-count guard, which #7228 fixed the same way on main, so main's version was taken.

Changed in 00bb8b0

• Module timeout below the 60-minute wait (20:21 point 1, Greptile thread). UploadToNuGetModule now sets .WithTimeout(AotWorkflowTimeout + 30 minutes).
• Start-up race when no aot.yml run is listed yet (20:12 point 1, 20:21 point 2, CodeRabbit outside-diff). An empty list now counts as pending until the 60-minute deadline. The timeout message says no run appeared, so the cause stays clear. Discovered runs that all finished without success still fail at once.
• Repository! null-forgiving (20:13 point 4). A missing or malformed GITHUB_REPOSITORY now fails with a clear message, like the SHA check.
• What counts as a pass, and dispatched publishes (20:12 points 2-3, 20:13 point 3, 20:21 point 3). Documented on WaitForAotWorkflowAsync: any successful run on the commit passes, whatever its trigger, because a push run and a dispatched run build the same code. A dotnet.yml publish dispatched on a commit with no aot.yml run fails closed. I kept that rule rather than filtering on Event == push, which would block a release where the push run flaked and a dispatched re-run passed. A PR run cannot match, because GITHUB_SHA on main is the merge commit, which no PR run builds.
• GitVersion outputs in the bash source (CodeRabbit thread). aot.yml passes them through env. The same pre-existing pattern in dotnet.yml is tracked in CI: dotnet.yml expands GitVersion outputs directly into bash run scripts #7229.

No change

• Pagination (20:12 point 2, 20:13 point 3). The query is filtered by HeadSha, so a single commit never comes close to the 30-run first page.
• Stale success masking a later failure on the same SHA (20:13 point 2). Both runs built the same commit, so a pass on one attempt is real evidence for that code. A later failure on the same SHA would be a flake or an infrastructure fault, not a regression.
• workflow_run or a reusable workflow instead of polling (20:13 point 1). A reusable workflow called from dotnet.yml puts the AOT jobs back on the dotnet.yml critical path for every PR, which is what this PR removes. workflow_run fires after aot.yml finishes but cannot join it with the dotnet.yml run that packed the packages. Polling only runs on publishing runs of main, so the held runner costs little.
• libraries.slnf built by grep (20:12 point 4, 20:13 point 6, 20:21 point 5). The step fails loudly when the filter finds no projects. A checked-in .slnf would have to be kept in sync with TUnit.CI.slnx by hand, which drifts silently in exactly the way the reviews are worried about. Deriving it from the slnx picks up new src/ projects automatically.
• Shared composite action for the version-export steps (20:21 point 5). Reasonable as a follow-up, not needed for this change.
• Branch protection (20:12 point 5, 20:13 point 5, 20:21 point 4). The AOT (…) checks have to be added to the required checks by a repository admin at merge, as the PR description says.

Review

I couldn't run the automated review skill, so I read the diff by hand. I did not build or run anything. Overall the change looks sound.

What I checked

• Dependencies: removing PublishTestProjectAOTModule from RunEngineTestsModule and the test-module dependencies from RunEngineAotTestsModule fits the goal. The Aot category keeps these modules out of the matrix via ignore-categories.
• Windows NuGet job: it selects only Packaging NuGetPackageTests, so it no longer runs PublishNugetTesterAOTModule. aot.yml covers Windows. Making the TestNugetPackageModule dependency optional is the right call, because the shared bin/obj folders still get ordered in local full runs.
• aot.yml: it passes the GitVersion values through env instead of expanding them into the script, which avoids injection through the branch name. It sets persist-credentials: false and contents: read. The libraries.slnf generation fails loudly when no projects are found.
• Release gate: UploadToNuGetModule.WaitForAotWorkflowAsync fails closed when GITHUB_REPOSITORY or GITHUB_SHA is missing. It treats a run that isn't listed yet as pending. The module timeout is above the wait timeout.

Suggestions (non-blocking)

1. Polling failures: the polling loop makes an Octokit call with no handling for a transient API error or rate limit. One 5xx during the 60-minute wait would fail the release step. A small try/catch that logs and retries would be more robust.
2. Pagination: ListByWorkflow returns the first page only. It is fine for a single SHA, but passing ApiOptions or filtering would make that explicit.
3. Wait on a failed run: if an aot.yml run for the commit fails, the release fails immediately, even when a re-run is in progress. The code handles that case correctly, because it counts a still-running run as pending. It is worth noting in the docs that a re-run has to be started before the gate evaluates.
4. Design: the gate polls from inside the publish module. A more declarative approach is a workflow_run-triggered publish job, or needs on a reusable workflow call. That would remove the 30s polling and the extra actions: read permission. It is a larger restructure, so the current approach is acceptable.
5. Branch protection: the PR description already mentions adding the AOT (…) checks to branch protection. Please make sure that gets done, since the release gate only covers publishing and not merging.

The > 50 guard change for the net472 expectation count is reasonable.

Good change overall.

Dispositions for the github-actions review at 20:33 and the AOT (windows-latest) failure on 00bb8b0, as of ee7dd48.

Fixed

• AOT (windows-latest) failed at restore (82149c1). Windows environment names are case-insensitive. The export step's GITVERSION_SEMVER merged with the GitVersion action's own GitVersion_SemVer, and bash saw only the action's spelling, so $GITVERSION_SEMVER was empty. Version was exported empty, TUnit.Assertions.Should's $(Version)-beta became invalid, and NuGet restore failed with MSB4181. The step now uses a GV_ prefix and fails with a clear error if semVer is empty. Linux and macOS were unaffected because their environment names are case-sensitive. CI: dotnet.yml expands GitVersion outputs directly into bash run scripts #7229 should use non-colliding names when it moves dotnet.yml to the same pattern.
• Transient API errors in the release gate (point 1, ee7dd48). An ApiException while listing runs is logged and retried until the 60-minute deadline, instead of failing the release.

No change

• Pagination (point 2). Already dispositioned: the query is filtered by HeadSha, so one commit never fills the first page.
• Re-run after a failed run (point 3). A re-run reuses the same run ID and shows as in progress, so the gate waits for it if it was started before the gate polls. If every run has already failed when the gate polls, failing the release is the intended behaviour; re-run the publish after the AOT re-run passes.
• Declarative workflow_run or reusable workflow (point 4) and branch protection (point 5). Already dispositioned in the 20:33 comment above.

Review

I read the diff but didn't build it or run the workflows. I found no blocking issues.

What works

• Moving the AOT publish and AOT-mode engine tests into their own aot.yml removes the CPU contention that made them the critical path. Nothing in dotnet.yml waits on them any more.
• aot.yml builds only the libraries, TUnit.Engine.Tests and the pipeline, which suits its narrower job.
• The GV_-prefixed, env-passed GitVersion export avoids script injection from the branch name and the case-insensitive environment names on Windows.
• UploadToNuGetModule now fails closed. It throws if GITHUB_REPOSITORY or GITHUB_SHA is missing, if every run for the commit finished without success, or if no run succeeds within the timeout. The module timeout is set above the wait, and actions: read is added.
• The PublishNugetTesterAOTModule dependency on TestNugetPackageModule is now optional, so a local full run still orders the two while aot.yml doesn't register it.

Suggestions (non-blocking)

1. The gate holds the ubuntu publish job. The wait can occupy that job for up to 60 minutes. That is acceptable, but a separate workflow_run-triggered or needs-style publish job would free the runner. At minimum, log which aot.yml run is being waited on.
2. A re-run can fail the gate early. If an attempt failed and a re-run was queued, the run's status may briefly read as completed/failure before the new attempt registers. The gate would then throw immediately. A short grace period or retry before failing would make that case more robust.
3. Branch protection. The new AOT (…) checks need adding to any required-checks list, as the PR notes. Since the release gate now enforces AOT success, consider documenting that coupling in workflows.md.
4. The > 50 guard is a weak check. The BuiltInExpectationMessageTests change from > 100 to > 50 makes the test pass on net472 but detects far fewer regressions. Computing the expected count per TFM (net472 gets 95) would keep the guard tight.

Overall this is a sensible CI restructure.

Review

This is a sound change. Moving the native AOT publishes into their own aot.yml workflow takes them off the critical path. Gating the release on that workflow keeps the AOT result from being dropped. I read the diff only and didn't run the pipeline. The Codex review comment on the PR was still running when I looked, so I can't say whether it raised anything.

What looks good

• UploadToNuGetModule fails closed if GITHUB_REPOSITORY or GITHUB_SHA is missing, if there's no aot.yml run, or if all runs finished without success.
• It tolerates transient ApiExceptions while the deadline bounds the retries.
• The module timeout (90 min) is set above the wait (60 min), so the module's own timeout can't cut the wait short.
• The GV_ env-var naming and passing GitVersion outputs via env rather than expanding them into the script are careful choices.
• Making the TestNugetPackageModule dependency optional on PublishNugetTesterAOTModule keeps local full runs ordered.

Concerns

1. The release job holds a runner while it waits. The dotnet.yml ubuntu job can now sit up to 60 minutes polling every 30s. The matrix gets shorter, but the publish job gets longer when aot.yml is slow. A more scalable design would be to trigger the publish from workflow_run on aot.yml completion, or from a separate small job that needs both workflows. That would also remove the need for actions: read and the polling code. If you keep polling, check the job-level timeout-minutes in dotnet.yml so it can't kill the wait.
2. Rerun races. The gate passes on any successful run for the SHA. That's fine for identical code, but a flaky-then-green rerun of a different trigger will also pass. This is acceptable and the comment documents it. It is worth keeping the in-code comment, since it is a deliberate trade-off.
3. Branch protection. The new AOT (…) checks must be added as required checks. Otherwise a PR can merge with a red AOT job, and the first sign is a blocked release on main. I'd call this out in the merge checklist.
4. Duplicate packing. aot.yml repacks on all three OSes, and the generated libraries.slnf filter greps TUnit.CI.slnx with a regex. The empty-result guard helps, but a project-type or path change could silently narrow the set. Consider checking the slnf into the repo, or deriving it with dotnet sln list-style tooling, so it can't drift.
5. Nit. WaitForAotWorkflowAsync catches ApiException only while UtcNow < deadline. After the deadline an ApiException propagates instead of the clearer timeout message. That's minor, but you could rethrow it as a TimeoutException with context.

The BuiltInExpectationMessageTests guard relaxation to > 50 is reasonable for the net472 symbol difference. It does weaken the guard, so a comment or a per-TFM expected count would be tighter.

Overall: approve with the follow-ups above, mainly branch protection and the runner-hold tradeoff.
