Fixes #480.

What was wrong

The Qlty Check job has never analyzed a single file. It passed on every PR because it found nothing to look at.

qlty check and qlty smells both default to changed-files-only and resolve the comparison from local branch refs. actions/checkout leaves PR runs on a detached merge ref with no local branch, so qlty fell back to HEAD, produced an empty file set, and reported ✔ No issues. actionlint, trufflehog and osv-scanner have never run once since the job was added in #30.

Separately, seven .qlty/qlty.toml entries were discarded on every run — printed as WARNING: ... will be ignored inside a job whose result was always green.

Beyond the issue

Three things #480 did not cover, found while verifying it:

  • --upstream alone would not have fixed osv-scanner. Its qlty plugin declares skip_upstream = true, so it is dropped from changed-file runs entirely. It needs its own --all pass.
  • osv-scanner can never scan the root package-lock.json. It is 2.68 MB; qlty silently skips files above ~2.1–2.5 MB (bisected in a scratch repo). Even with --all it only reaches src/test/vscode-notebook-perf/package-lock.json.
  • qlty smells exits 0 even with findings, so that step is informational and can never fail the job, mode = "block" notwithstanding.

Changes

.github/workflows/ci.yml

  • Explicit --upstream "$UPSTREAM_REF" on both commands, passed via job-level env rather than inlined into run:.
  • Job restricted to pull_request. Under --upstream origin/${{ github.base_ref || 'main' }} a push to main resolves to origin/main == HEAD and analyzes nothing — the same vacuous green this PR is fixing. A gate that only claims to run where it can actually compare is more honest than a checkmark that means nothing.
  • New reporting-only qlty check --all --filter osv-scanner --no-fail step.
  • timeout-minutes: 310. Three minutes was only ever plausible for a job that did no work.

.qlty/qlty.toml

  • exclude_patterns moved above every table header. In TOML a bare key after [[source]] binds to that table; note it has to clear [[plugin]] too, which comes first in the file. Dropped build/** — 48 tracked source files live there, so activating that pattern would newly hide real code from the scanners — and .git/**, which is never a qlty target.
  • Six smell names were Code Climate's, not qlty's. Renamed file_lengthfile_complexity, cognitive_complexityfunction_complexity, duplicate_codeidentical_code + similar_code; dropped function_length, large_class, long_parameter_list, which have no equivalent. Thresholds are qlty's defaults, not the old numbers — the units differ (duplicate_code = 6 meant lines; identical_code counts structural mass), so carrying them over would have been meaningless precision.

Verification

Installed qlty 0.642.0 locally and ran everything against a faithful reproduction of the CI checkout — a cloned repo on a detached PR-merge HEAD with no local branches.

Claim Evidence
Bug reproduced JOBS: 0, No modified files for checks were found on your branch. — matches the CI log in #480 verbatim
Fix works there Same state, --upstream origin/mainJOBS: 2, actionlint + trufflehog on 3 files
Gate actually blocks Same state plus a PR adding a workflow with github.evnt_nameexit 1, actionlint flags it
Config clean qlty config validate silent, exit 0; qlty config show lists all patterns and smells
osv-scanner runs 12 medium CVEs in the perf-test lockfile, exit 0 under --no-fail
Blast radius --upstream HEAD~20 (197 changed files) → ✔ No issues, 13s
Repo checks npm run format passes; actionlint clean on the modified ci.yml

Not verified: trufflehog's detection. Invocation is proven (the invoke YAML shows the command and 300 chunks / 3.85 MB scanned), but it runs --only-verified, so a positive control would need a live credential.

Caveats

  • Qlty Check will no longer appear on pushes to main. Harmless if it is a required status check — those gate PRs — but I could not read branch protection to confirm (API returned 403).
  • The dependency-scan step is reporting-only and prints 12 untriaged medium CVEs. Dropping --no-fail is a one-line change; tracked in src/test/vscode-notebook-perf has a stale lockfile that no CI job gates on #482.

Summary by CodeRabbit

  • CI Improvements

    • Code quality checks now run specifically for pull requests against the correct base branch.
    • Added a 10-minute limit to code quality checks.
    • Dependency scanning now runs independently across all files and reports findings without blocking CI.
  • Configuration

    • Updated analysis exclusions to skip generated, dependency, coverage, and minified files.
    • Refined complexity and code similarity checks with updated thresholds.

The Qlty Check job has never analyzed a single file. Both `qlty check` and
`qlty smells` default to changed-files-only and resolve the comparison from
local branch refs; actions/checkout leaves PR runs on a detached merge ref
with no local branch, so qlty fell back to HEAD, found nothing, and reported
`No issues`. actionlint, trufflehog and osv-scanner have never run.

The failure is invisible from a laptop, where a local branch always exists.

- Pass an explicit `--upstream` to both commands and restrict the job to
  pull_request, the only event with a real base ref. Under the previous
  snippet a push to main resolves to `origin/main` == HEAD and analyzes
  nothing, recreating the same vacuous green.
- osv-scanner's plugin declares `skip_upstream`, so changed-file runs drop it
  entirely. Give it its own `--all` step, reporting-only for now: it finds 12
  medium CVEs in src/test/vscode-notebook-perf/package-lock.json today.
- Raise the timeout from 3 minutes, which was only ever plausible for a job
  that did no work.

Also fix seven qlty.toml entries that were silently discarded on every run:

- `exclude_patterns` sat under `[[source]]`, so TOML bound it to that table.
  It has to precede every table header, `[[plugin]]` included. Dropped
  `build/**` (48 tracked source files live there, so activating the pattern
  would newly hide real code from the scanners) and `.git/**` (never a target).
- Six smell names are Code Climate's, not qlty's. Renamed to file_complexity,
  function_complexity, identical_code and similar_code; dropped function_length,
  large_class and long_parameter_list, which have no equivalent. Thresholds are
  qlty's defaults rather than the old numbers, whose units do not carry over.

📝 Walkthrough

Walkthrough

The Qlty configuration now excludes dependency, distribution, coverage, and minified files. It uses updated complexity and code-similarity checks with new thresholds. The Qlty CI job runs only for pull requests, compares against the pull request base reference, and has a 10-minute timeout. A separate non-blocking OSV dependency scan checks all files.

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

Merge Risk: 🔵 Low · up to 1cf20

The workflow now analyzes pull-request files and enforces quality findings, but the dependency report is skipped when an earlier quality check fails, reducing vulnerability visibility on affected PRs. This is a bounded follow-up risk with explicit owner awareness; the PR remains mergeable.

A step with no `if:` carries an implicit success(), so a failing `qlty check`
or `qlty smells` skipped the OSV report on exactly the runs someone is already
looking at. Guarded the same way as the Codecov upload at ci.yml:142.

Adopts the ref-conditional invocation from deepnote-internal's Code Quality job
(deepnote-internal 1f754c86cc), which the previous commit's `if: pull_request`
job guard worked around instead: a pull request compares against its base, and
anywhere without a base scans the whole tree rather than not running at all.

osv-scanner stays out of the full-tree filter — the dedicated step below still
reports its findings without gating on them, and gating would turn main red on
12 untriaged CVEs.

Guarding `qlty smells` with !cancelled() comes from watching the opposite play
out in that repo: an unrelated image-size CVE failed `qlty check` on develop,
and the implicit success() on the following steps silently skipped both the
smells pass and madge circular-dependency analysis for nine days.

Verified locally against every command the expression can produce:

  qlty check --upstream origin/main               -> exit 0
  qlty smells --upstream origin/main              -> exit 0
  qlty check --all --filter=actionlint,trufflehog -> exit 0, 16.5s
  qlty check --all --filter=osv-scanner --no-fail -> exit 0, 12 reported
