Bring CodeQL back to pull requests as jobs of PR CI itself (needed by
ci-ok, no polling), narrowed to first-party code, while push to main,
the weekly run, the dry run and the release keep the full scan.
- codeql.yml: one leg per language (c-cpp, javascript-typescript,
python, actions), scope in .github/codeql/codeql-config.yml. The full
scan traces the whole build, vendored C included. The PR scan
(light: true) analyses each selected language's whole first-party
scope; c-cpp compiles the third-party objects before tracing
(scripts/build.sh --vendored-only) and then traces the first-party
build plus the vendored files the PR changes (--reuse-vendored
--retrace-from, make -W). Diff-informed analysis (codeql-action
v4.38.1, forced on for PR calls) only restricts reported alerts.
The alert check moves into each leg and reads the analysed ref.
Push and PR runs cancel superseded runs per language; dispatched
runs never cancel. Compiler cache off so every compile is traced.
- pr.yml: a codeql job runs the legs of the selected codeql-* lanes;
ci-ok needs it.
- select-lanes.sh: codeql-cpp/-js/-py/-actions lanes, selected by a
change in their scope (any C/C++ incl. vendored; JS/TS, Python and
workflows inside the config's paths minus paths-ignore) and by every
full run (undeterminable diff, workflows, build, CodeQL machinery).
--codeql-scope LANGUAGE prints a list's in-scope paths.
- codeql-retrace-vendored.sh: the vendored C files a PR changes (empty,
never narrowing, when the diff cannot be determined).
- Makefile.cbm: cbm-third-party builds the vendored prod objects only.
- tests: the gate contract pins the new layout; the selector contract
pins that a C change always selects the C scan, an undeterminable
diff selects every language, and a vendored-only change retraces
exactly the changed vendored files. Selector fixtures, ci-ok's job
map, the replay's codeql-action failures (lane codeql-cpp) and the
interface probes follow.
