Summary

This PR adds 43 YAML fixture files under ui/src/features/visual-editor/doc/__tests__/fixtures/. It adds no code and changes no existing file.

Why

The tests of the YAML document model need real workflow files with odd forms. They are kept apart so that the code PRs stay small. The fixtures are read by the document model tests that start in PR 11; the model code itself comes in PR 10.

Changes

  • 43 new files, 0 modified.
  • Syntax edge cases: anchors-aliases, block-scalars, folded-line-break, flow-collections, flow-maps-unicode, quoted-keys-and-values, odd-indentation, long-lines, empty-file, invalid-yaml.
  • Comments: comments-everywhere, build-comments, unicode-comments, multidoc-comments-markers, spec-harness-comments.
  • Multi-document files: multidoc-empty-between, multidoc-subdag, multidoc-unnamed-later.
  • Step forms: shorthand-steps, nested-array-run, nested-parallel-groups, map-steps, map-steps-forbidden, foreach-string-items.
  • Real-world workflows: demo-agent-release, demo-graph-etl, chain-router, router-numeric-band, router-regex-keys, harness-acp, scheduler-cron, xlsx-japanese, embedded-local.

How to review

  1. Skim the file names for coverage.
  2. Open the two or three fixtures you know best and check that they are valid Dagu YAML, except invalid-yaml.yaml, which is invalid on purpose.

Pay attention to fixtures that contain secrets or host paths. None is expected.

Tests

No test file in this PR. The fixtures are data for the tests in PR 11 and later.

Screenshots

No visible UI change in this PR. The document model that reads these files drives the editor shown in the final UI.

Summary by CodeRabbit

  • Tests
    • Expanded workflow fixture coverage for YAML syntax and formatting, including anchors, aliases, comments, Unicode, multiline values, quoted values, and multiple documents.
    • Added scenarios covering dependencies, routing, handlers, scheduling, parallel execution, browser flows, agent workflows, embedded commands, and data-processing tasks.
    • Included cases for runtime context, output capture, configuration, and malformed or unusual input.
    • These changes add test examples only; no end-user functionality changes are included.

Walkthrough

The pull request adds YAML fixtures for visual-editor documentation tests. The fixtures cover YAML syntax and document structure, workflow execution and configuration, and browser, agent, ACP, embedded-executor, and spreadsheet examples.

Changes: Visual Editor YAML Fixtures

Layer / File(s) Summary
YAML syntax and document structure
ui/src/features/visual-editor/doc/__tests__/fixtures/{anchors-aliases,block-scalars,comments-everywhere,flow-collections,long-lines,invalid-yaml,map-steps-forbidden,map-steps,multidoc-comments-markers,multidoc-empty-between,multidoc-unnamed-later,nested-array-run,nested-parallel-groups,odd-indentation,quoted-keys-and-values,shorthand-steps,unicode-comments}.yaml
Fixtures demonstrate scalar and collection forms, comments, quoting, indentation, shorthand steps, and multi-document streams.
Workflow execution and configuration
ui/src/features/visual-editor/doc/__tests__/fixtures/{build-comments,chain-router,config-cli,demo-graph-etl,embedded-local,foreach-string-items,handler-env,handlers-chain,folded-line-break,multidoc-subdag,run-context,scheduler-cron,router-numeric-band,router-regex-keys,spec-outputs-heredoc,spec-subdag-parallel}.yaml
Fixtures define dependent steps, routing, handlers, foreach processing, graph ETL, runtime context, scheduling, and sub-DAG execution.
Browser, agent, and data integration examples
ui/src/features/visual-editor/doc/__tests__/fixtures/{browser-flow-maps,demo-agent-release,embedded-custom-executor,flow-maps-unicode,harness-acp,spec-harness-comments,spec-xlsx-convert,xlsx-japanese}.yaml
Fixtures configure browser actions, agent and ACP harnesses, an embedded executor, XLSX conversion, and Japanese spreadsheet extraction.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: Low · previous review d8428

The fixtures are suitable for document-model testing, but running the browser fixture with untrusted data is unsafe, and repeating the spreadsheet workflow can fail. Neither fixture has an identified current execution consumer.

Inline comments:
Review comments at @conformance/spec013_step_run/from_runs_test.go:
- Line 166: Update the invalid run ID assertion using reject to compare the
complete error message returned by the server instead of checking for the
substring "run"; match the exact-message assertions used by the neighboring
cases.
- Around line 28-30: Update the `T` assignment in the build output to avoid
`date +%s%N`, which is unsupported on macOS; include the shell PID so tags
differ across runs while preserving the `image_tag` output.

Review comments at @conformance/spec083_continuous_runs/api_test.go:
- Around line 216-222: Increase the elapsed-time threshold in the samples
request test from 500 milliseconds to a more tolerant bound, such as 2 seconds,
to reduce failures on loaded CI runners. Keep the existing request and response
assertions unchanged.

Review comments at @internal/persis/dagrun_repository_ephemeral.go:
- Around line 90-95: Update Status.IsActive so it treats NotStarted as active
alongside Running, Queued, and Waiting, preventing the ephemeral-run cleanup
guard from removing old NotStarted runs.
- Around line 139-150: Update the repository’s RecentStatuses flow to reject or
otherwise safely handle a negative limit before calling either store or
mergeRecentStatuses; follow the existing error contract and do not introduce a
default limit.

Review comments at @internal/runtime/runner.go:
- Around line 455-458: Reorder the completion handling around `finishNode` so
`finishNode` and `clampDependentStarts` complete, and `wg.Done()` is called,
before notifying the runner through `doneCh`. Account for Go’s last-in-first-out
defer execution so dependents and final status processing cannot proceed before
timestamp clamping.
- Around line 954-956: Update the dependent-clamping loop around
plan.Dependents(node.id) so ClampStartedAt applies only to dependents that start
in the current run. Exclude skipped or reused dependents carried from a source
run, preserving their historical StartedAt and FinishedAt timestamps.

Review comments at @internal/samples/dir.go:
- Around line 12-22: Update dirFor to prevent distinct step names from sharing a
store directory: when sanitization changes stepName, append a short hash derived
from the original name to the sanitized directory name. Preserve the existing
name for inputs that require no sanitization, and update TestSamplesStoreDir to
expect the hashed name for sanitized inputs.

Review comments at @internal/samples/events.go:
- Around line 133-138: Update finish to include the tracker’s running failure
count in the stopped event when an outage is active, and update loadTracker to
restore the count from the newest EventStopped or EventFailed carrying one,
preserving the larger count when restoring the outage tracker.

Review comments at @internal/service/frontend/api/v1/dags.go:
- Around line 351-362: Make the expectedSha256 comparison and spec write in the
DAG update handler atomic by moving the comparison into dagRepository.UpdateSpec
as a compare-and-swap operation. On a hash mismatch, leave the spec unchanged
and preserve the handler’s 409 conflict response; ensure the repository
operation is safe across frontend instances.

Review comments at @specs/013-step-run.md:
- Line 327: Update the `--outputs-from` description to specify that it carries
the work directory and outputs only from skipped steps that a selected step
depends on. Align the wording with the narrower rule implemented by
`carryingSteps` and keep the CLI help and reference documentation consistent.

Make the build output portable. date +%s%N fails on macOS.

BSD date on macOS does not support %N. It prints a literal N. Two runs that start in the same second then produce the same tag. require.NotEqual(t, firstTag, secondTag) at Line 61 fails on that platform.

Use a value that differs per run without %N. The shell PID differs for each run.

Update the `T` assignment in the build output to avoid `date +%s%N`, which is
unsupported on macOS; include the shell PID so tags differ across runs while
preserving the `image_tag` output.

Assert the exact error text. "run" accepts almost any 400 body.

The body of almost every 400 response for this request contains the substring run (for example outputsFromRuns). This assertion passes even if the server rejects the ID for the wrong reason. The other cases assert the full message.

Assert the message that the server returns for an invalid run ID.

Relax the wall-clock bound on the samples request.

assert.Less(t, elapsed, 500*time.Millisecond) measures one HTTP round trip on a loaded CI host. The test reads three years of tiers through the full server stack. A slow or shared runner can exceed 500 ms with no regression, so the check is likely to fail intermittently. The unit test TestSamplesTiers already uses a 2 s bound for the reader alone. Use a similar margin here, or keep the bound only as a benchmark.

Include NotStarted in the active-status check.

IsActive() excludes NotStarted, so an old NotStarted ephemeral run can pass the guard and be removed after its CreatedAt exceeds the TTL. Queued and Waiting are already protected. StatusBuilder.Create accepts NotStarted and assigns CreatedAt, so this path is feasible.

Handle negative limit values before listing runs.

A negative limit reaches the file store and causes listRecentDAGRuns to slice with a negative bound. The same value also reaches the ephemeral store and merge helper.

The repository does not define a default of 10 for recent statuses. Reject or otherwise handle negative limits before delegating to the stores. Do not add the proposed limit = 10 default without an applicable contract.

Preserve timestamps on skipped, reused nodes.

When a selected run executes a and carries a skipped dependent b from a source run, exclude b from this clamp. ClampStartedAt can replace b’s historical StartedAt and FinishedAt with a’s finish time, although b did not execute in the selected run. Clamp only dependents that start in the current run.

Make the store directory unique for each step name.

dirFor maps every character outside [A-Za-z0-9_-] to _. Different step names can therefore get the same store directory:

  • my beat and my_beat both map to my_beat.
  • Non-ASCII names of the same length collide. For example, 日本 and 中国 both map to __. The repository fixtures include Japanese step names.

If two continuous steps in one run collide, two recorders on separate goroutines write the same raw/, minute/, and events.jsonl files. Each recorder has its own store instance. The tiers then mix samples from both steps. putFile rewrites can drop records that the other recorder appended. The event tracker also mixes the outages of the two steps. The API reader uses the same Dir function, so each step's charts show the combined data.

Add a short hash of the original name when sanitization changes the name. TestSamplesStoreDir expects my_beat, so update that test too. This is a new store, so no existing layout needs migration.

Keep the outage failure count across a restart.

loadTracker restores failed from newestFailed.FailedCount. A failed event is written only when the outage starts and then once each repeatFailedAfter (1 h). Failures after the newest failed event are not in any event. If the recorder stops during an outage, those failures are lost. The recovered event after the restart then reports a FailedCount that is too low.

Example: one failed event with count 1 is written, 30 more samples fail, and the recorder restarts. After 2 more failures, the recovered event reports 3 instead of 33. TestOutageAcrossRestart checks only Outage, so it does not catch this.

To fix this, store the running count in the stopped event when the tracker is in an outage. Then restore the count from the newest event that carries one. One side effect: toStepEvents sets failedCount for any event kind with FailedCount > 0, so the API will also show it on stopped events.

🐛 Proposed fix

In internal/samples/recorder.go finish:

-	if err := r.writeEvent(Event{Time: r.now().UTC(), Kind: EventStopped}); err != nil {
+	stopped := Event{Time: r.now().UTC(), Kind: EventStopped}
+	if r.trk.inOutage {
+		stopped.FailedCount = r.trk.failed
+	}
+	if err := r.writeEvent(stopped); err != nil {
 		return err
 	}

-	var earliest, newestFailed *Event

The handler reads the current spec and compares its hash at lines 351-362. It writes the new spec later, at line 377. No lock or compare-and-swap covers the time between the check and the write.

Two editors can send expectedSha256 with the same base hash at the same time. Both checks pass, and the second write silently replaces the first. That is the lost update that the API contract excludes ("the server writes nothing and returns 409"). Guard the check and the write with one per-file lock, or move the comparison into dagRepository.UpdateSpec.

A process-local lock protects only one server process. For more than one frontend instance, the repository must do the compare-and-swap.

Make the expectedSha256 comparison and spec write in the DAG update handler
atomic by moving the comparison into dagRepository.UpdateSpec as a
compare-and-swap operation. On a hash mismatch, leave the spec unchanged and
preserve the handler’s 409 conflict response; ensure the repository operation is
safe across frontend instances.

`dagu start --only <step>` runs only the named steps, as the `steps` field does. Repeat `--only` to select more than one step.

- `--outputs-from <run-id>` is the command line form of `outputsFromRunId`. It carries the outputs of every skipped step, and the work directory, from one finished run.

Make the --outputs-from scope match the outputsFromRunId rule.

Line 327 says that --outputs-from "carries the outputs of every skipped step". Line 299 and line 361 give a different rule. Under that rule, only skipped steps that a selected step depends on carry outputs. A skipped step after the selection carries nothing. carryingSteps in internal/intake/steps.go implements the narrower rule. The CLI help in internal/cmd/start.go (lines 65-66) and skills/dagu/references/cli.md (line 24) also say "every skipped step". Readers get two different rules from the same spec. Use one wording in all three places.

Update the `--outputs-from` description to specify that it carries the work
directory and outputs only from skipped steps that a selected step depends on.
Align the wording with the narrower rule implemented by `carryingSteps` and keep
the CLI help and reference documentation consistent.

Keep the extracted order number out of the shell command.

If the page supplies an order number containing $(...), Dagu inserts that text before the shell runs. The shell then executes the command substitution, despite the double quotes. Write the value with file.write, or pass it as an environment variable and print that variable instead. (raw.githubusercontent.com)
