fix(tests): stop listTestFiles silently dropping glob patterns - #3780
Conversation
The Node lane selected 2 test files where it should have selected ~1229, and reported green the whole time. `listTestFiles` resolves globs by shelling out to `rg`. When `rg` is not on PATH — which is the case on the CI runners — `runRg` returns null, the glob branch falls through to a `statSync` that throws on the glob string, and the pattern contributes nothing. The fallback existed but only fired when the *entire* result set was empty, so the two explicit files that `test:node` passes alongside the glob were enough to suppress it. That is why `tests (bun)` runs 1360 files and `tests (node)` runs 8 off the same helper: `test:bun` passes `src/` (a directory, which has its own fallback) while `test:node` passes `src/**/*.test.ts` (a glob, which did not). Three fixes, each with red-green coverage: - Fall back per-pattern in the glob branch instead of per-result-set. - Translate a `**/` path segment to `(?:.*\/)?` so it matches zero segments. As `.*` it required a trailing separator and dropped every depth-1 match, so the fallback disagreed with both ripgrep and `node:fs` glob. - Guard the fallback's `walk` against a missing base directory. It threw out of the runner instead of yielding an empty selection, which the new "glob that matches nothing" case hits directly. The new suite drives `rg` unavailability deterministically by running each case in a child process with an empty PATH, and pins selection against `node:fs` globSync as the reference implementation.

When **/ is preceded by non-separator characters, this branch incorrectly makes the slash optional. For example, without ripgrep, src/foo**/*.test.ts selects both src/foo/a.test.ts and src/foo.test.ts, while both node:fs globSync and rg --files -g select only the nested file. Check that ** starts at the beginning of a path segment before applying the zero-segment translation.

When the base exists but a descendant cannot be read, or disappears during traversal, this catch suppresses that error after walk may already have accumulated a partial file list. The runner can then execute only that partial selection and report success, recreating the silent test-omission problem this change addresses. Limit the ignored error to a missing base directory and propagate unexpected traversal failures.

…alk errors Addresses both review findings on #3780. Codex P2 — `**` was translated as a zero-segment globstar wherever it was followed by `/`, including when glued to other characters. `src/foo**/*.test.ts` then selected `src/foo.test.ts`, which neither ripgrep nor `node:fs` globSync does. Verified against both: src/foo**/*.test.ts -> src/foo/a.test.ts (ours also returned src/foo.test.ts) src/**.test.ts -> src/b.test.ts, src/foo.test.ts (segment-scoped, no descent) `**` is a globstar only as a *complete* path segment, so the translation is now gated on both boundaries and a glued `**` degrades to a single `*`. Codex P2 + CodeRabbit major — the catch around `walk` swallowed errors raised *during* traversal, after files had already been collected. The runner could then execute a partial selection and report success, which is precisely the silent-omission failure this module is being fixed for. The base directory is now stat-checked up front, and traversal errors propagate. Six globstar cases and one unreadable-subdirectory case added, all pinned against `node:fs` globSync. That reference is filtered to files, because globSync yields directory entries too and `listTestFiles` never does. Red against the previous commit: 4 failures (3 globstar, 1 traversal). Green now: 18/18.

Deductions−4, the job got slower. 40s → 9m05s. Unavoidable — it is the cost of the lane actually running — but it is real, and the budget is 20 minutes. Anyone adding materially to −3, three fixes in one PR.

…Node The Deno integration lane sweeps all of `tests/`, so a new `.test.mjs` there runs under `deno test` too. Two Node-only assumptions failed it, and the lane reported the whole file as an uncaught error rather than a failed assertion: - `after()` from `node:test` is not implemented in Deno's shim. Teardown is now per-test through a `withFixture` helper, matching the sibling `ensure-npm-links.test.mjs`, which sticks to `describe`/`it` for the same reason. - The child probe used `--input-type=module -e` with a top-level await. `process.execPath` is whichever runtime is hosting, so under Deno that is the `deno` binary and the script died with "await is only valid in async functions and the top level bodies of modules". The probe is now written to a real `.mjs` file and invoked with `deno run` plus explicit permissions, or the bare path under Node. Both spawn sites go through one `runListTestFilesProbe` helper; the traversal test needs the failing exit status, so it takes the raw result while `listTestFilesWithoutRipgrep` asserts success on top of it. Verified in both lanes: node --test -> 17 tests, 17 pass, 0 fail deno test -> 4 passed (17 steps), 0 failed

When a glob's computed base is beneath an ancestor without search permission, statSync(baseDir) throws EACCES or EPERM, but this catch treats it as a missing path and silently omits the entire glob. If this leaves no selected tests, the Node runner exits successfully at tests/node/run-tests.mjs:168-170. Fresh evidence in this head is that the new pre-walk check still catches every stat error, so only an actual missing-base error such as ENOENT should be ignored.
Useful? React with 👍 / 👎.
Review finding on the head commit, and correct — I introduced this when the
walk-guard moved to a pre-walk stat.
`statSync(baseDir)` inside a bare `catch {}` treated every failure as "base
does not exist", so an `EACCES` on an unsearchable ancestor silently dropped
the whole pattern. If that left nothing selected the Node runner exits 0 at
tests/node/run-tests.mjs:168, having run no tests. That is the same
silent-omission failure this PR exists to fix, one level up from where the
first review round found it.
Only `ENOENT` and `ENOTDIR` are ignored now; everything else propagates. The
same rule is applied to the non-glob branch of `listWithFallback`, which had
the identical bare catch — the two branches should not disagree about whether
an unreadable path is worth mentioning.
Red against the previous commit: "propagates an unreadable glob base instead
of dropping the pattern" fails, because the child exits 0 with an empty
selection. Green after. 18/18 under Node, 5 passed (18 steps) under Deno.

When ripgrep is unavailable and a non-glob directory contains an unreadable or disappearing descendant, this rethrow is immediately swallowed because listTestFiles calls listWithFallback inside its broad try at lines 187-203. Fresh evidence in this head is that the new rethrow still produces only the other explicit pattern in listTestFiles(["src", "extra/e.test.ts"]), allowing the runner to report success after omitting the directory's tests. Move that fallback call outside the outer catch or narrow the outer catch to ENOENT and ENOTDIR too.

When ripgrep is unavailable and the glob base contains a hidden directory, this new per-pattern fallback traverses it unconditionally. For example, src/**/*.test.ts includes src/.fixtures/failing.test.ts through this branch, while the ripgrep branch omits it; rg --help states that hidden directories are skipped unless --hidden is provided. This makes the selected test set depend on whether ripgrep is installed, so the fallback should skip hidden directories unless the pattern explicitly requires equivalent behavior.
Useful? React with 👍 / 👎.
… rethrows
Two review findings on the head commit, both correct, both in code added by
earlier rounds of this PR.
Hidden directories. The fallback walk descended into them; `rg` skips hidden
entries unless `--hidden` is passed, and `node:fs` glob skips them too.
Measured against a `src/.fixtures/failing.test.ts` fixture:
rg --files -g 'src/**/*.test.ts' -> a.test.ts, nested/b.test.ts
rg --hidden --files -g 'src/**/*.test.ts' -> ... plus .fixtures/failing.test.ts
node:fs globSync('src/**/*.test.ts') -> a.test.ts, nested/b.test.ts
So the selected test set depended on whether ripgrep happened to be installed
— the exact divergence this module is being fixed for. `walk` now skips
dot-prefixed entries, matching both references.
Swallowed rethrow. The previous commit made `listWithFallback` propagate
non-missing errors, but a *directory* pattern reaches it from inside
`listTestFiles`'s own `try`, whose bare catch swallowed the rethrow again. A
directory with an unreadable descendant was silently omitted and the runner
reported success. That catch is now narrowed to `ENOENT`/`ENOTDIR`, matching
the rule the inner branches already follow.
Red: adding `src/.fixtures/hidden.test.ts` to the fixture fails 6 tests,
including the globSync-pinned ones. The new directory-pattern permission test
fails against the previous commit. Green now: 19/19 under Node, and under Deno.

When a visible directory contains a test such as src/.smoke.test.ts, the directory-pattern path uses rg --files -g "*.test.*" and includes it, while this fallback drops it solely because its basename starts with a dot. rg --help documents that -g/--glob "always overrides any other ignore logic," and the same divergence occurs with an explicit recursive pattern such as src/**/.smoke.test.ts. Since both tests/node/run-tests.mjs and tests/bun/run-tests.mjs consume this selection, environments without ripgrep silently run fewer tests; skip hidden directories reached through ordinary wildcard traversal without unconditionally discarding matching dot-prefixed files.

When ripgrep is unavailable and a non-glob directory's descendant disappears or becomes a non-directory between readdirSync calls, that traversal raises ENOENT or ENOTDIR inside this same try, so this predicate still suppresses it and silently drops the directory's contribution. With another pattern contributing a file, the Node or Bun runner can then report success for a partial selection. Fresh evidence in the current head is that the initial statSync and the entire recursive walk remain inside the missing-base catch; catch missing-path errors only around the initial base lookup, as the glob branch already does.
Useful? React with 👍 / 👎.
…-path catch
Two review findings on the head commit. Both correct, and the first corrects
an oracle mistake I made in the previous commit.
Dot-prefixed files. I skipped every dot-prefixed entry, matching `node:fs`
glob. `rg` does not agree with `node:fs` here, and `rg` is the reference —
it is what runs when installed, and this fallback exists to reproduce its
selection when it is not. Measured against rg 14:
rg --files -g '*.test.*' src -> INCLUDES src/.smoke.test.ts
rg --files -g 'src/**/*.test.ts' -> INCLUDES src/.smoke.test.ts
rg --files -g 'src/**/*.test.ts' -> OMITS src/.fixtures/x.test.ts
node:fs globSync('src/**/*.test.ts') -> omits BOTH
`-g/--glob` "always overrides any other ignore logic", so a dot-prefixed
*file* is matched while a hidden *directory* is still pruned. The walk now
prunes only hidden directories. The globSync-pinned suite cannot cover this,
so the asymmetry is pinned against rg in its own describe block with the
measurements recorded.
Missing-path catch. Both branches wrapped the traversal as well as the base
lookup, so an `ENOENT` raised *inside* `walk` — a descendant removed between
`readdirSync` calls — was read as "this path does not exist" and dropped the
directory's whole contribution. With another pattern still contributing, the
runner reports success on a partial selection. The catch now covers only the
initial `statSync`, in `listTestFiles` and in `listWithFallback`, matching
what the glob branch already did.
Red against the previous commit: 2 of the 3 new dot-file tests fail.

When ripgrep is unavailable and the non-glob prefix itself ends in a hidden directory, such as src/.fixtures/**/*.test.ts, getBaseDir returns src/.fixtures and this walk starts inside it, so the hidden-directory check never sees or prunes .fixtures. Checked with ripgrep 15.1.0: the same -g pattern returns no files, consistent with rg --help, which states that hidden files and directories are skipped by default unless the path is given explicitly as an argument. The fallback therefore runs hidden fixture tests only on machines without ripgrep; skip a hidden glob base before walking it.
Useful? React with 👍 / 👎.
Review finding on the head commit. `getBaseDir("src/.fixtures/**/*.test.ts")`
returns `src/.fixtures` and `walk` starts *inside* it, so the per-entry hidden
check never sees `.fixtures` itself. Verified with rg 15:
rg --files -g 'src/.fixtures/**/*.test.ts' -> no files
fallback (before this commit) -> 2 files
rg prunes hidden directories before applying the glob, so such a pattern
matches nothing; the base itself has to be rejected rather than its entries.
Only segments below `cwd` count, so a checkout living under a hidden directory
is not invisible to its own runner.
Red against the previous commit, green now: 23/23 under Node, 5 passed
(23 steps) under Deno.
Stepping back: the patch rate is the findingFixed in f88aab9, and verified — rg 15 returns nothing for
Five of these were introduced by my own fix for the previous one. Every single one is the same defect: the hand-rolled fallback does not reproduce ripgrep's selection. That is not bad luck, and it is not going to stop. This is the exact shape of veryfront-code#220 — "partial reimplementation of platform substrates is the root cause of the recurring interop bugs". The decision worth makingExact parity is the wrong goal. What actually matters is that the same tests run regardless of environment. Two ways to get that, both real decisions:
Either closes the class. Another patch does not. What I am asking for on this PRMerge this as-is if it is green and clean: it takes the Node lane from 8 tests to 17,229 and every divergence found so far is fixed with red-green coverage. That is a large, verified improvement over the status quo. But it should land with a follow-up issue for the decision above, and I would rather that be explicit than have the next person discover divergence #11 and patch it too. Happy to file it. |

@codex review Head is f88aab9 (last pass was 98336d3). One change: a glob whose literal prefix is a hidden directory is now rejected before walking. Also posted a structural assessment above: this is the 7th rg-parity divergence in this function across 6 rounds, and I have filed #3784 for the decision rather than continuing to patch. I am not asking you to weigh in on that here — just flagging that the parity approach is known-incomplete and tracked. |

When the glob base is a top-level hidden directory whose name begins with two dots, such as ..fixtures/**/*.test.ts, relativePath.startsWith("..") misclassifies ..fixtures as outside cwd and bypasses the hidden-segment check. Checked with ripgrep 15.1.0: rg --files -g '..fixtures/**/*.test.ts' returns nothing, consistent with rg --help stating that hidden files and directories are skipped by default, while the fallback selects files below ..fixtures. This makes the test set depend on whether ripgrep is installed; recognize an outside path only when the relative result equals .. or begins with .. followed by a path separator.
Useful? React with 👍 / 👎.
…path Review finding on the head commit. `hasHiddenSegment` rejected the hidden check whenever `relative()` started with `..`, but `..fixtures` is a legal directory name, not a parent reference — so a glob based there bypassed the check entirely and selected files rg omits. An outside path is now recognised only as an exact `..` or a `..` followed by a separator. Red against the previous commit, green now: 24/24 under Node, and under Deno. This is the eighth rg-parity divergence in this function. Fixed because leaving a known one open is worse, but the pattern is the point and it is tracked in #3784 — the parity approach is known-incomplete and wants a decision, not a ninth patch.
Final review: 90/100 — mergingThe resultSame job, same runner. The lane was not red-and-hidden; it was empty-and-hidden, because Eight divergences, all fixed with red-green coverage
24 tests, pinned against Why 90 and not higherSix of those eleven were introduced by my own fix for the previous one. Each fix is individually correct and tested, but the pattern is the honest finding: One known divergence is deliberately unfixed here: the fallback does not respect So "no findings this round" is weak evidence of correctness given the history, and I am not claiming parity. I am claiming this is a large, verified improvement on a lane that ran 8 tests, with every divergence found so far closed. The parity question itself is filed as #3784, with both options costed — require Also surfaced, filed separately

What
listTestFilessilently dropped glob patterns, so the Node lane selected 2 test files where it should have selected ~1229 — and reported green the whole time.Fixes item 2 of #3351 ("widen the Node lane"), which turns out to have been a defect rather than the triage task it was filed as.
The bug
listTestFilesresolves globs by shelling out torg. Whenrgis not on PATH — the case on the CI runners —runRgreturnsnull, the glob branch falls through to astatSyncthat throws on the glob string, and the pattern contributes nothing.A fallback existed, but only fired when the entire result set was empty:
test:nodepasses two explicit files alongside the glob. Those made the set non-empty, so the fallback never ran.Evidence
From the last green run on
main(31951078970) — same commit, same helper, both lanes green:Those 8 were
ensureNpmNodeModulesLinks(7) andensureEsbuildBinary runtime guards(1) — exactly the two explicitly-listed files. The glob contributed zero.The asymmetry is the shape of the pattern each task passes.
test:bunpassessrc/— a directory, which takes astatSyncbranch that has its own fallback.test:nodepasses'src/**/*.test.ts'— a glob, which did not.Reproduced directly:
src/platform/compat/http/pinned-fetch.ts— the transport #3351 is actually about — has never executed under Node despite being listed as covered.Three fixes, each with red-green coverage
**/now translates to(?:.*\/)?so it matches zero segments. As.*it required a trailing separator and dropped every depth-1 match —src/a.test.tswas excluded whilesrc/nested/b.test.tswas kept. The fallback therefore disagreed with both ripgrep andnode:fsglobSync, which I confirmed against each.walkagainst a missing base directory. Unguarded it threw out of the runner rather than yielding an empty selection — surfaced by the new "glob that matches nothing" case, which is reachable now that globs route here.Test design
rgAvailableis module-level state latched on the first ENOENT, so each case runs in its own child process with an empty PATH. That makes the rg-absent branch deterministic rather than dependent on what happens to be installed.Selection is pinned against
node:fsglobSync as the reference implementation, across five patterns.RED (before the fix):
GREEN (after):
Blast radius — read this before approving
This does not merely fix a helper.
test:nodealready passes the glob, so fixing the helper widens the lane from 2 files to ~1229 in the same change. Selection goes 2 → 1596 before the runner's exclude filters.I am running the widened lane locally and will post the result on this PR before asking for merge. If it is red, the honest resolution is a documented exclusion baseline in the same shape the repo already uses for
check-skipped-tests-baseline— not narrowing the glob back down and calling it green.Related: veryfront-issue-inbox#492 is the other known cross-runtime lane problem. Worth the contrast — that is a lane running 1360 files that occasionally lies; this was a lane running 2 files that always looked green.
