fix(review): let the revert-oracle see feature-gated Rust tests - #4090
Conversation
cargoRunner() always ran a crate's default feature set, so a Rust test gated `#[cfg(feature = "x")]` (whole-file `#![cfg(...)]` or item-level, directly above `#[test]`) compiled out entirely — the oracle collected the same test count before and after a revert and reported UNOBSERVED for a change it never even compiled in. This is the Rust half of the gap #4050 described; #4079 closed the Python half and deliberately left this one out. scripts/lib/revert-oracle-rust-features.mjs reads a changed/added Rust test file's cfg attributes and turns any(...)/all(...)/bare feature gates into the required --features combination(s). planRuns() now spawns one cargo plan per required combo per crate, falling back to the existing single default-features plan when a file has no feature gate at all (the overwhelming majority of Rust branches see zero behavior change). Both directions proven on a synthetic scratch crate matching #4024's own item-level any(gate_a, gate_b) shape: a gated test that asserts on the changed value reads OBSERVED when reverted; one that does not reads UNOBSERVED, not a silent pass. Note: the "csg_manifold_gate and csg_topology_gate must not be enabled together" premise carried over from #4079's scoping note does not hold in this codebase -- test.yml runs the combined --features csg_manifold_gate,csg_topology_gate as its own CI job, and issue_098_v5c.rs has live #[cfg(all(...))] cases for both together. No exclusivity handling was needed as a result; any() maps to separate per-feature plans and all() maps to one joint combo. No budget raised: revert-oracle.mjs stays at 528/528 lines and check-test-revert-oracle.mjs at 612/612. Refs #4050, #4079, #4024, #4085.

…andled cfg shapes (#4085) Adversarial review of hunt-revert-oracle-rust-features (9981ebf) found three defects in revert-oracle-rust-features.mjs: 1. The doc comment claimed only bare/any()/all() cfg shapes occur in this repo's Rust test tree and that "nested any(all(...)) does not occur." False: not(...) gates a real #[test] today at rust/geometry/tests/triangulation_invariance.rs:2168,2188 (not(any(...))) and rust/geometry/tests/issue_582_583_regression_test.rs:198 plus rust/geometry/src/csg/csg_tests.rs (bare not(feature = "...")). Corrected the comment to name these sites instead of asserting they don't exist. 2. detectRequiredFeatureCombos silently returned [] for any cfg shape it could not parse (not(...), nesting beyond one level, cfg_attr(feature = "x", test), an attribute between #[cfg] and #[test]). planRuns() then fell back to a default-only plan, so a test gated by one of these shapes never compiled under any plan and the run reported BASELINE-BROKEN with 0 collected — reproduced against the live triangulation_invariance.rs and issue_582_583_regression_test.rs files directly. Chose the smaller, explicitly-preferred fix: detect each unhandled shape and throw UnhandledCfgShapeError naming the file, line, and shape, rather than extending the parser to genuinely evaluate not(...) — real negation support needs planRuns() to always include the default no-features plan alongside explicit combos (today it only falls back to default when zero combos are found at all), which is a caller-contract change, not a parser extension. 3. A line- or block-commented-out `#[cfg(feature = "ghost")]` above #[test] was read as a real gate. Added stripComments() so commented-out cfg attributes are ignored, verified not to mask a real gate on the next test in the same file. Did not add a plan-count cap (the lower-priority item in the review) — out of scope for this pass; flagging for whoever picks it up next. Tests: 9 new cases in revert-oracle-rust-features.test.mjs, including the real not(any(...)) shape from triangulation_invariance.rs and the all(not(A), B) idiom from issue_098_v5c.rs:119-136, both asserting the loud failure with correct file/line. node --test scripts/lib/revert-oracle*.test.mjs: 68 before -> 77 after. Mutation check: commenting out the not(...) throw turns exactly the 3 targeting tests red (17 pass / 3 fail), confirming they catch a reversion to the old silent behavior. Verified unchanged: cargoRunner(crate, []) still emits exactly ["test","--no-fail-fast","-p",crate] (no --features flag) for an ungated file, and both directions of the branch's own synthetic-crate proof (revert-oracle-rust-feature-gate.test.mjs) still pass: OBSERVED when the gated test asserts on the change, UNOBSERVED when it doesn't. scripts/check-test-revert-oracle.mjs and scripts/lib/revert-oracle.mjs are untouched — both sit at their exact module-size budget (612 and 528 lines) with zero headroom, so all new logic lives in the already-uncapped sibling module revert-oracle-rust-features.mjs (now 186 lines). check-module-size.mjs, check-test-wiring.mjs, and check-source-text-assertions.mjs all pass. Also noted for the maintainer: this branch conflicts with #4079 (open, adds Python support to the same oracle) — both add a branch inside planRuns()'s per-group loop and both edit the same import block in check-test-revert-oracle.mjs. Confirmed with a direct diff against upstream/pull/4079/head; semantically reconcilable into one if/else if/else, needs hand-merging by whoever merges second.

Merge-order note, found while fixing the same problem on #4079. This branch is cut from before #4084 landed (merge-base Three separate changes now add a thin hook to that same dispatcher:
#4079 already hit this: merged onto current So once this branch picks up both #4084's and #4079's hooks through a real merge, the file will grow past 621 and the budget will need re-measuring again. Not fixable in advance — the number depends on merge order — but whoever merges this second should expect it and set the row to the measured count rather than guessing. Worth noting the shape rather than just the number: this file is a dispatcher that three independent features each legitimately extend by a few lines, while its budget is pinned to whatever the last merge happened to produce. Each PR is individually green and the collision only appears on the merged tree, which is why it went unnoticed until a full-sequence integration test. |

…make stripComments string-literal aware Adversarial review of hunt-revert-oracle-rust-features (254d78e, #4085) found two more defects, both the same failure mode the branch exists to eliminate. 1. planRuns() is called at check-test-revert-oracle.mjs module top level, before the tool's own try{}/uncaughtException handler exist. A cfg shape detectRequiredFeatureCombos refuses to plan a run for was therefore a genuine unhandled exception: a raw stack trace on stderr, no JSON despite --json, and Node's default exit code of 1 -- which collides with EXIT_UNOBSERVED. Reproduced directly against a synthetic crate with a not(feature = "x") gate above a real #[test]: exit 1, no JSON, raw stack trace. Fixed by catching UnhandledCfgShapeError around the planRuns() call and handing it to die() with its own exit code (6, EXIT_UNHANDLED_CFG_SHAPE) -- die()'s ABORT formatting, JSON payload when --json is passed. Since check-test-revert-oracle.mjs is at its exact module-size budget (612 lines, zero headroom -- see scripts/module-size-allowlist.txt), the new logic (the exit constant, the JSON shaping, and the try/catch itself) lives in the already-uncapped sibling lib/revert-oracle-rust-features.mjs as requiredFeaturePlanOrDie()/unhandledCfgShapeReport(), leaving the dispatcher's own diff at two single-line changes (the import, and the planRuns() call site) and its line count unchanged at 612. 2. stripComments() blanked from the first "//" to end of line with no notion of "am I inside a string", so `let s = "//"; #[cfg(feature = "x")]` read the "//" INSIDE the string literal as a comment start and erased the real cfg gate on that line -- detectRequiredFeatureCombos returned [] and the gated test would never compile in under any plan, exactly the silent false UNOBSERVED this branch fixes elsewhere. Reproduced directly. Rewrote stripComments as a single-pass scanner that tracks string/raw- string/char-literal state: double-quoted strings ("..." with \" / \\ escapes, covering byte strings too since their escaping is identical), Rust raw strings (r"...", r#"..."#, ..., including br"..."), and char literals ('x', '\n', '\'', '\u{7f}'), distinguished from a lifetime ('a) by requiring a matching closing '. Line/column numbers are still preserved by blanking comment text to spaces rather than removing it. Not a full Rust lexer (no raw identifiers) but the reproduced shape -- "//" inside an ordinary double-quoted string -- is handled rather than disclaimed away. Tests: node --test scripts/lib/revert-oracle*.test.mjs: 77 pass before -> 85 after (1 new end-to-end synthetic-crate test for the exit-code defect, 7 new stripComments unit tests for the string-literal defect). Mutation- checked both: reverting either fix turns its new test(s) red (confirmed 1 fail and 4 fail respectively) while leaving the fix in place keeps all green. Verified unchanged: cargoRunner(crate, []) still emits exactly ["test","--no-fail-fast","-p",crate]; both directions of the branch's own synthetic-crate proof (revert-oracle-rust-feature-gate.test.mjs) still pass (OBSERVED and UNOBSERVED); issue_098_v5c.rs still returns combos: [] cleanly with no throw (the not(...)/all(...) shapes there are on const declarations, not directly above #[test], so the throw's scoping is unaffected). check-module-size.mjs, check-test-wiring.mjs, and check-source-text-assertions.mjs all pass. Impact on the #4079 conflict (adds Python support to the same oracle, touches the same import block and planRuns()'s per-group loop): this change touches the import line (line 93) but not the planRuns() loop itself, only the call site above it -- a smaller footprint than the prior #4085 commit left, but still an additional line in that import block for whoever reconciles the two branches.

Do not let deep cfg nesting bypass UnhandledCfgShapeError.
A valid gate such as #[cfg(any(all(any(feature = "a", feature = "b"), feature = "c"), feature = "d"))] exceeds NEST2. Neither regex matches it, so parseCfgExpr() never rejects the unsupported nesting and the gated test is silently ignored.
Use balanced attribute extraction before checkHandledShape/parseCfgExpr, then add a test with nesting deeper than any(all(...)).

Detect feature gates on enclosing test modules.
With #[cfg(feature = "gate_a")] mod gated { #[test] fn f() {} }, TEST_CFG_RE does not match the module attribute. detectRequiredFeatureCombos() returns no combo, so Cargo runs default features and compiles the complete module out. The oracle can then report UNOBSERVED without running f.
Track enclosing cfg scopes, or fail when a feature-bearing cfg applies to a container that can contain tests. Add this module-gate case to the unit tests.

Reject supported-shape expressions that contain non-feature predicates.
parseCfgExpr('all(feature = "gate_a", target_os = "none")') returns [['gate_a']]. On a normal target, Cargo enables gate_a but still compiles the test out because target_os = "none" is false. This recreates the silent false-UNOBSERVED result that the structured unsupported-shape path is intended to prevent.
Reject mixed predicates unless the detector can evaluate all of them for the current run.

The revert-oracle job needs fixtures before this can clear #4024Your PR body already says this doesn't by itself resolve #4024. I verified the mechanism rather than taking that on trust, and found a second, separate reason — one that's worth fixing here because it blocks the payoff of this PR.

Both ideally conditional, so the common path stays fast and a required gate doesn't slow down for lanes it isn't using. I've left this to you because the dependency footprint of a required gate is a maintainer call, and doing it well probably means one change covering both lanes rather than two PRs each solving half.

Correction to my earlier triage on this PR. I said The branch head has the file at 612 lines against a 612 budget. It passes. The 621 exists only in So there was never anything wrong with this PR in isolation, and "shrink the file" was aimed at the wrong target. Sorry for the noise. Two consequences:
Worth naming the pattern, because it is not a one-off. Main went red twice today from exactly this shape, and both were mine to notice:
Both are fixed in #4101. That makes four instances in one session of green-alone / red-merged, counting this one and the #4029/#4039 conflict. When a shared ratchet, a shared allowlist or a shared file is involved, a branch-level green says nothing about the merge.

) * fix(ci): install the Python toolchain revert-oracle's pytest lane needs #4079 taught scripts/lib/revert-oracle.mjs to classify test_*.py / *_test.py as tests and route them through `python3 -B -m pytest` (see scripts/lib/revert-oracle-python.mjs). The classification is correct, but the revert-oracle job in test.yml installs no Python toolchain -- checkout, pnpm, node, a build-artifact download, then the oracle. GitHub's Ubuntu runner image ships python3 but not pytest, so any diff that reaches this lane now fails with BASELINE-BROKEN (No module named pytest) instead of a real verdict, blocking a required gate. Adds a `python` output to the `changes` job's paths-filter (tools/ ifcopenshell_reference/** plus this workflow file) and gates two new conditional steps on it: actions/setup-python, then `pip install -r tools/ifcopenshell_reference/requirements.lock pytest`, mirroring ifcopenshell-parity.yml's `full` job. The full requirements.lock, not bare pytest: test_validate_export.py's SchemaConformanceHasTeeth cases (#4043) import ifcopenshell and are unittest.skipUnless(HAVE_IFCOPENSHELL, ...), so bare pytest would run them as silent skips instead of the assertions the oracle needs to revert against. The job's own `if` (frontend || rust) is unchanged -- this only gates the install steps, not job scheduling, so a diff touching only tools/ifcopenshell_reference/** with nothing under packages/apps/rust would still not trigger the job at all; that's a separate, narrower gap than what's fixed here. The live case is #4048, whose diff includes tools/ifcopenshell_reference/ test_validate_export.py. Same class of problem as the Rust lane: this job also can't run feature-gated Rust tests because it never fetches fixtures (see #4090's thread), which makes #4024 fail the same way. Not fixed here -- separate lane, separate fixture-fetch mechanism. * fix(ci): widen the revert-oracle python filter to match pythonTestOwner's repo-wide reach The `python` output on the `changes` job's paths-filter matched only `tools/ifcopenshell_reference/**`, but `pythonTestOwner` in scripts/lib/revert-oracle-python.mjs walks up from ANY `test_*.py` / `*_test.py` file to the nearest project marker with no directory restriction. Two locations already fell outside the filter: scripts/perf/evidence/**/reproduce/test_*.py (owned by a nearby requirements.txt) and rust/python/tests/test_bindings.py (owned by rust/python/pyproject.toml, though in practice cargoTestOwner's Cargo.toml-first walk claims that file before pythonTestOwner is ever tried). A diff touching only the evidence fixture matched `rust` (job runs) but not the old `python` filter (install skipped), so the oracle routed the test to `python3 -m pytest` on a runner with no pytest installed and failed BASELINE-BROKEN, exit 3 -- the exact failure this workflow's python install step exists to prevent. Replace the directory glob with `**/test_*.py` / `**/*_test.py`, matching TEST_FILE_RE's python alternatives in scripts/lib/revert-oracle.mjs byte-for-byte so the filter is derived from the same basename patterns the routing itself keys on and can't drift out of sync again the way the directory-scoped version did. Also: correct two comments that said routing happens "under tools/ifcopenshell_reference" -- it's marker-based and repo-wide -- and fix the `actions/setup-python` version label (SHA 5fda3b95a4ea91299a34e894583c3862153e4b97 is v7.0.0, not v5; the SHA itself was already correct). * chore: empty commit to re-trigger test.yml (missing lanes on #4102) --------- Co-authored-by: Louis Trümpler <78563314+louistrue@users.noreply.github.com>

Closes #4085

The problem

planRuns()loop and the same import block incheck-test-revert-oracle.mjs. Semantically reconcilable into oneif/else if/else; whoever merges second will need to do it by hand.Scope

#[cfg(test)] mod testsinline, so reverting production reverts the tests too — the oracle flags that separately as heading forINCONCLUSIVEand suggests--mutation. Feature support removes one of the two obstacles.Summary by CodeRabbit
