* Package scanners: cut false positives and make the CI gate blocking
scan_packages.py and scan_npm_packages.py red-failed on legitimate
library code, so the security-audit steps were left advisory. Reduce
the false positives at the source and flip both gates to blocking.
scan_packages.py:
- Scan code only: blank comments and bare docstrings/doctests before
matching (line numbers preserved), so prose and >>> examples cannot
trip a finding.
- Drop the platform.system() branch from the anti-analysis regex (under
DOTALL it matched across the whole file, so every cross-platform
library tripped it) and fix the dead /proc/self/status alternative.
- Add a reviewed baseline allowlist (scan_packages_baseline.json) keyed
on (package, basename, check): only non-baselined CRITICAL/HIGH exit
1, and a new kind of finding in a listed file still fails.
- sdist fallback: when --with-deps cannot resolve a shard (a sdist-only
package or a version conflict), drop to per-spec and fetch the raw
sdist from the PyPI JSON API (no pip build, no setup.py), so every
package is still scanned and no shard exits 2.
scan_npm_packages.py:
- Mirror the code-only JS/TS scanning (blank // and /* */ comments,
string/template/regex aware) and the baseline allowlist. The npm
corpus is clean today, so the baseline is empty.
security-audit.yml:
- Flip both scan steps to blocking (SCAN_ENFORCE=1), capturing the
scanner exit via PIPESTATUS so tee does not mask it.
tests/security: add coverage for the strip, baseline and sdist paths.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Address review feedback on the package scanners
- Do not blank f-strings during code-only scanning (they evaluate at
import); and when a file uses exec/eval, rescan the original for
payload carriers hidden in a docstring/string so exec(__doc__) style
payloads stay visible.
- sdist fallback: recover transitive deps with their version specifier
(fetch the pinned version, not latest), and recover deps in the
--no-deps branch too so a sdist-only transitive dependency is still
scanned instead of silently skipped.
- Baseline: key by package-relative path, not basename, so a future
same-named file in another directory is not auto-suppressed.
Regenerated the baseline accordingly.
