Behaviour change: none

Only CI changes: no file under src/ or packages/.

Problem

• A docs-only pull request gets no Buildkite pipeline: - PR is only docs, skipping tests! (.buildkite/ci.ts:1988). The build and 9 test files read docs/.
• The 1,048 lint rule pages are a build input (scripts/glob-sources.ts:73): an edit changes the binary with no build.
• scripts/runner.node.ts:4251 copies the rule. A moved file is judged by its new path.

Fix

• isDocsOnlyChange() in scripts/buildkite.ts is the rule for both scripts. A path under docs/lint/rules/ is not docs. A moved file also counts under its old path.
• compiler-docs-links.test.ts needs no build. It moves to the source-lints lane, which now runs for docs/**.
• Verified: test/internal/source-lints/docs-only-change.test.ts fails with main's scripts. Also the lane, tsc, and stand-in runs of both scripts.
• Self-reviewed: 29 concerns raised, 27 addressed. Rejected: a scan for readers of docs/ (it misses some) and unverified prior-art links.

Background

• The pipeline step runs ci.ts, which uploads every other job. Test jobs run runner.node.ts. Source lints is a 40 s GitHub Actions job.
• Considered the step as the only judge: that removal belongs to ci: take the PR file list from git in the pipeline step and stop test shards from asking GitHub #45839, with its file list from git. Also considered a docs-only canary job, and the full pipeline per tested page.

Downsides

• docs/compiler/*.mdx and, after docs: generate the Output blocks of the minifier page from bun build #48113, minifier.mdx stay unchecked on a docs-only pull request. Their tests run only on Buildkite.
• An edit of only a lint rule page now costs the ordinary pipeline: 188 jobs. None in a year.
• The link test runs only in Source lints, not a required check.

Notes

Who reads docs/ (main at 2596ac5)

Reader	Files	What the check needs
the build: lintRuleDocs in scripts/glob-sources.ts:73, emitLintDocs in scripts/build/codegen.ts:535, src/lint/driver/explain.rs:31	docs/lint/rules/*/**/*.mdx	it is the build
test/cli/lint/rule-docs.test.ts	docs/lint/rules/**, index.mdx, reports.json	a bun built from the pages
test/cli/lint/explain.test.ts:6	docs/lint/rules/*/**/*.mdx	a bun built from the pages
test/bundler/compile-trim-runtime-texts.test.ts:219	docs/lint/rules/reports.json	a built bun
test/cli/aot-docs.test.ts:65	docs/compiler/*.mdx without executables.mdx and bytecode.mdx	a built bun: it runs the commands on the pages
test/aot/explain.test.ts:72 (#47942)	docs/compiler/explain.mdx	a built bun
test/aot/libraries-known-not-to-work.test.ts:14	docs/compiler/libraries.mdx, compatibility.mdx	a built bun for the programs. The page assertions (line 315) need none
test/internal/trim/features.test.ts:107	docs/compiler/size.mdx	only loadFeatures(). The file imports bun:internal-for-testing for its other tests
src/aot/report/wording/tests.rs:3 (include_str!)	docs/compiler/explain.mdx	cargo (the cargo-test step)
compiler-docs-links.test.ts	every docs/**/*.mdx, docs/docs.json	no build

• The first four rows are covered by the prefix docs/lint/rules/.
• The last row is covered by the move.
• The five rows between them are the first Downsides bullet. Three of them hold a check that needs no built bun. Those checks stay where they are on purpose: each is in a file that needs the build or cargo for its other tests. The size.mdx check can move to the lane in a later change, with src/trim/features/** in paths:.

Reproduction

Three edits, each under docs/ only. I ran them at 7ca0042 with the canary build of that commit.

1. docs/docs.json: the redirect destination /compiler/compatibility becomes /compiler/compat. compiler-docs-links.test.ts fails: every redirect leads from a page that is gone to a page.
2. docs/lint/rules/eslint/eqeqeq.mdx: the description: line changes. rule-docs.test.ts fails with eslint/eqeqeq: description differs from `bun lint --rules`. Rebuild bun. and explain.test.ts fails 2 tests. Only a build of the pull request can judge this edit.
3. docs/compiler/types.mdx: the txt block 6 becomes 7. aot-docs.test.ts fails: docs/compiler/types.mdx > line 40: bun compile ./visits.ts && ./visits.

On main the pipeline step calls all three docs-only. Example of the skip: build 138231 of #48092, 1 job, 13 s.

With this change:

Edit	Pipeline step	Check that judges it
1	no pipeline	Source lints fails (bun test test/internal/source-lints/ on bun 1.4.4: the redirect test)
2	187 jobs uploaded, the list is stored, each shard runs its tests	rule-docs.test.ts and explain.test.ts with the build of the pull request
3	no pipeline	none. This is the first Downsides bullet

These results come from the real scripts under node, with a stand-in buildkite-agent on PATH and fetch replaced. I opened no docs-only pull request to see them on Buildkite. The CI run of this pull request cannot take the docs-only path, because it changes ci.ts.

The stand-in runs

node .buildkite/ci.mjs as a build of a fork pull request, for nine file lists:

List from GitHub	main	this branch
docs/bundler/esbuild.mdx	no pipeline	no pipeline
docs/docs.json	no pipeline	no pipeline
docs/compiler/types.mdx	no pipeline	no pipeline
docs/lint/rules/eslint/eqeqeq.mdx	no pipeline	34 steps, 187 jobs, list stored
a rule page moved to docs/lint/eqeqeq.mdx	no pipeline	34 steps, 187 jobs, both paths stored
src/cli/README.md moved to docs/project/cli.md	no pipeline	34 steps, 187 jobs, both paths stored
scripts/agent.ts copied to a new file	34 steps, 187 jobs, the new path stored	the same
docs/bundler/esbuild.mdx, src/cli.rs	34 steps, 187 jobs, list stored	the same
GitHub answers 403	34 steps, 187 jobs, no list stored	the same

node scripts/runner.node.ts --exec-path=<a missing file> as a test shard. Exit 1 at Could not find executable means that the shard reached its tests. Exit 0 means that it ran none.

Order	main	this branch
stored list: a lint rule page	exit 0, no test	reaches the tests
stored list: a docs page and src/cli.rs	reaches the tests	reaches the tests
stored list: docs/bundler/esbuild.mdx (the step stores no such list)	exit 0, no test	exit 0, no test
no stored list, GitHub answers with a lint rule page	exit 0, no test	reaches the tests
no stored list, GitHub answers with docs/bundler/esbuild.mdx	exit 0, no test	exit 0, no test
no stored list, GitHub answers 403	reaches the tests	reaches the tests

The first row is why both scripts change together. With only ci.ts changed, a pull request that edits a rule page builds on every lane, and every shard then skips its tests.

Self-review, and why the runner keeps its check and its query

The first version of this branch made the pipeline step the only judge. It removed the runner's check, and the query to GitHub that a shard makes when the step stored no list. The self-review asked for the runner as it is now. Its reasons, which I checked:

• The step stored no list in 2,256 of 8,859 pull request builds in 18.5 days (builds 129557 to 138556). ci: take the PR file list from git in the pipeline step and stop test shards from asking GitHub #45839 reports the cause: the shared token is out of quota (HTTP 403). In those builds the shard's own query is the only source of the list.
• A shard uses the list for every pull request: a changed test runs first and alone, and a new test that fails gets the label (new).
• ci: don't skip tests when GitHub PR-files API fails; cache via meta-data #29890 kept the shard's query on purpose, as a fallback "only if meta-data is missing".
• ci: take the PR file list from git in the pipeline step and stop test shards from asking GitHub #45839 removes the check and the query together with a list that the step takes from git. Its description says that the removal alone should not ship.

So this change gives the runner the shared rule and nothing else. The removal stays with #45839.

29 concerns were raised. 27 are addressed: the runner as above (20 of them), the test that both scripts call the rule, the old path of a moved file, the names in the test file, the comment on the rule, the title, the README text and this description. 2 are rejected:

• A test that scans the tree for readers of docs/ and holds them in an allowlist. It is one more list to keep, and a text scan misses a reader that gets the path from another module, as rule-docs.test.ts does.
• Links to the CI of other projects as prior art. I did not verify them.

After the review on this pull request (4df1bb5)

• The old path counts only for a file with status renamed. GitHub also sets previous_filename for a copied file, and a copy does not change its source. With the source in the list, a fork that copied scripts/agent.ts was refused by the guard for bake inputs: This pull request changes what CI's images are baked from (scripts/agent.ts). Now that build uploads its pipeline, as on main.
• The call-site test reads lines. Its first form used a pattern that consumed the next line, so an if directly above the check hid the check.
• The source-list test asks for one docs file in the lists, not for more than 1,000.
• Not done: a test that runs both scripts. The lane has no pinned node for them, and ci: take the PR file list from git in the pipeline step and stop test shards from asking GitHub #45839 adds that kind of test (test/internal/runner-pr-files.test.ts).

Measurements

• copies of the docs-only rule: 2 -> 1 function with 2 callers (git grep).
• pipeline step per evaluation: +1 call, +0 startsWith with a path outside docs/ in the list (1 and 1, 21 and 21), +n on an all-docs list of n paths (411 and 822).
• shard orders that exit 0 without a test: 4 of 6 -> 2 of 6. The two that remain are docs-only lists with no rule page.
• build-input files that a docs-only pull request can change with no build: 1,048 -> 0 of 8,735 (globAllSources(), 17 lists).
• docs-only commits on main in a year that now get a full build: 0 of 92. Open docs-only pull requests that touch docs/lint/rules/: 0 of 159. A full build is a median of 188 jobs, 1,835 job-minutes and 71 minutes (106 finished builds).
• Source lints runs on main in a year: 3,237 -> 3,368 of 4,565 commits (+131 for docs/**: 92 docs-only, 39 mixed. +0 for scripts/runner.node.ts). On pull requests: +65 builds in 18.5 days on 5,512, about 3.5 a day.
• Source lints: 195 tests in 42 files -> 202 in 44. The last 40 runs on GitHub before this change took 33 to 46 s each. The two runs of this pull request took 38 s and 36 s.
• compiler-docs-links runs per pull request build: 11 Buildkite lanes -> 0, and 1 in Source lints when docs/ changes.
• scripts/buildkite.ts exports 31 -> 33. The bun binary is the same: git diff --stat over src, packages, scripts/agent.ts, scripts/build/ci-images/spec.ts and scripts/glob-sources.ts prints nothing.
• Required checks on main are buildkite/bun and Format. Source lints is not one of them.
• diff: +140/-22 in 8 files.

The tests

docs-only-change.test.ts has 4 tests. With main's scripts the file does not load: Export named 'isDocsOnlyChange' not found. One change at a time:

Change	Tests that fail
the rule without the docs/lint/rules/ clause	the table (4 rows), the moved file, the source lists (1,048 pages)
the rule without the length check	the table
the old path of a moved file is dropped	the moved file
the source of a copied file counts as changed	the moved file
ci.ts decides with main's inline rule	the call sites
runner.node.ts decides with main's inline rule	the call sites

• The source-list test sees the 17 lists of scripts/glob-sources.ts. It does not see a file that the build reaches by a fixed path or an include_str!.
• No test runs main() of ci.ts or of runner.node.ts. The stand-in runs above are the check of those two hunks.
• scripts/runner.node.ts joins the paths: of the lane, because the call-site test reads it.
• The call-site test takes the line above each skip statement. A comment that is added or removed above the check does not change its result.

What stays as it is

• The skip for every other docs-only pull request: 1 job, 13 s.
• In a build whose step got no list, a shard that gets a docs-only list from GitHub skips its tests. In builds 138141 and 138142, 143 and 144 of 165 shards did. Build 130709 passed with 160 of 160 shards skipped.
• The file list is cut at 500 entries (scripts/buildkite.ts:453). ci: take the PR file list from git in the pipeline step and stop test shards from asking GitHub #45839 repairs that with a list from git. One case is gone: a pull request with source files and 500 or more pages was docs-only when its first 500 names were under docs/. With a rule page among them it now gets a build.
• docs/compiler: if the owners want those pages judged on the pull request, it is one more clause in isDocsOnlyChange(). That clause must not cover executables.mdx and bytecode.mdx, which only the link test reads. Each such pull request then costs the ordinary pipeline.
• Links between pages outside docs/compiler are judged by no test. The link test reads links from and to docs/compiler, the Compiler tab and the redirects.
• The two paths: lists of source-lints.yml are kept by hand.
• A branch cut before this change uses its own copy of both scripts until it takes main.
• test/expected-durations.json loses the entry of the moved test. The lane is not in that table.

#45839

• ci: take the PR file list from git in the pipeline step and stop test shards from asking GitHub #45839 takes the file list from git in the pipeline step, and removes the runner's check and the shard's query. It conflicts with main today in runner.node.ts (2 hunks). With this branch it conflicts in ci.ts (1 hunk), runner.node.ts (1) and scripts/buildkite.ts (2).
• After either merge order, each place that decides must call isDocsOnlyChange(). The call-site test fails when one does not. When ci: take the PR file list from git in the pipeline step and stop test shards from asking GitHub #45839 removes the runner's check, the expectation for runner.node.ts in that test goes with it.
• Its git list has both paths of a moved file, as the list here has now.

Status: ready for review. The change is complete, and it needs a maintainer to decide and merge.

How I reproduced the problem. On main at 7ca0042 I made three edits, each under docs/ only:

1. docs/docs.json: the redirect destination /compiler/compatibility changed to /compiler/compat.
2. docs/lint/rules/eslint/eqeqeq.mdx: the description: line changed.
3. docs/compiler/types.mdx: the txt block 6 changed to 7.

The rule at .buildkite/ci.ts:1988 calls that change docs-only, so the pipeline step uploads no pipeline (- PR is only docs, skipping tests!). With the canary build of that commit, bun test fails four test files on those edits:

• test/cli/compiler-docs-links.test.ts: every redirect leads from a page that is gone to a page
• test/cli/lint/rule-docs.test.ts: eslint/eqeqeq: description differs from `bun lint --rules`. Rebuild bun.
• test/cli/lint/explain.test.ts: 2 tests
• test/cli/aot-docs.test.ts: docs/compiler/types.mdx > line 40: bun compile ./visits.ts && ./visits

I ran .buildkite/ci.mjs and scripts/runner.node.ts under node with a stand-in buildkite-agent to see what each script decides for a file list. The tables are in the Notes of the description.

CI on 4df1bb5.

• The checks that run this change pass: Source lints (the new tests and the moved link test), Lint JavaScript (it type-checks scripts/ and .buildkite/ci.ts) and Format.
• Buildkite build 138828 ran the pipeline step and the test runner of this branch. The step stored both paths of the moved test in pr-all-files.
• In that build 183 jobs passed and 1 failed. The 4 jobs of the darwin any x64 test lane did not start.
• The failed job is test/aot/heap-limit.test.ts on alpine x64: a compiled program crashes under ulimit -v. This change has no file under src/ and does not touch that test. bun run ci:errors marks the failure as pre-existing. The other tests that failed passed on a second run alone.

Pull request: #48256

[coderabbitai]

Walkthrough

The change adds shared docs-only classification that accounts for renamed paths and excludes documentation lint-rule paths. The Buildkite pipeline and test runner use this classification, and source-lint workflow filters and tests are updated.

Changes

Docs-only CI handling

Layer / File(s)	Summary
Collect paths and classify docs-only changes scripts/buildkite.ts, test/internal/source-lints/docs-only-change.test.ts	Pull request file handling includes both current and previous paths for renamed files. The classifier accepts nonempty lists of docs/ paths unless a path starts with docs/lint/rules/. Tests cover classification, renamed paths, and discovered source lists.
Use classification in CI .buildkite/ci.ts, scripts/runner.node.ts, .github/workflows/source-lints.yml, test/internal/source-lints/docs-only-change.test.ts, test/internal/source-lints/README.md, test/internal/source-lints/compiler-docs-links.test.ts, test/expected-durations.json	Both CI entry points use the shared classifier to decide whether to skip work. Workflow path filters add scripts/runner.node.ts and docs/**. Source-lint documentation and tests are updated, and the compiler-docs-links duration entry is removed.

Suggested reviewers: dylan-conway, jarred-sumner

Merge Risk: Minimal · up to 4df1b

The shared classification preserves CI for lint-rule changes and renames across documentation boundaries. No new merge-blocking issue is established; the incomplete-rename edge case already existed.

Full details: Title check

Explanation

The title names two changes: the build is no longer skipped for lint rule pages, and compiler docs links are checked on docs-only pull requests. Both match the changeset. The shared isDocsOnlyChange() rule excludes docs/lint/rules/ from docs-only, and compiler-docs-links.test.ts moves to the source-lints lane, which runs for docs/**. The title is long (103 characters) and joins two changes with a comma, but it is related to the main change and is specific enough to scan.

Full details: Description check

Explanation

The description follows the repository template. It has both required sections: "What does this PR do?" (behaviour change, problem, fix, and downsides) and "How did you verify your code works?" (the reproduction, stand-in runs, measurements, and test results). It also gives specific remediation context, such as the affected files, the docs-only skip behavior, and the related pull request #45839. The author states the scope clearly: no changes under src/ or packages/, the new isDocsOnlyChange() rule shared by ci.ts and runner.node.ts, and the move of compiler-docs-links.test.ts to the source-lints lane. The description is detailed and mostly complete. It is not vague or generic, and it does not stray from the topic.

[claude]

Nothing blocking. The comments below are optional suggestions. There is no need to push a fix for them before merging.

Beyond the inline findings, I also traced the other readers of allFiles now that a renamed file contributes its previous_filename: the modified-test prioritization at scripts/runner.node.ts:1779 and :3515 only reorders paths that exist in the test list, so a renamed test's old path matches nothing and changes no ordering; and importing scripts/buildkite.ts from the new source-lint test runs nothing at module scope but env reads, matching how the sibling lints already import scripts/glob-sources.ts.

Extended reasoning...

The change replaces two inline docs-only checks in .buildkite/ci.ts and scripts/runner.node.ts with a shared isDocsOnlyChange() in scripts/buildkite.ts that excludes docs/lint/rules/ and treats an empty list as never docs-only, makes renamed files count under both paths, moves compiler-docs-links.test.ts into the source-lints lane and adds docs/** to that workflow's path triggers. It touches CI gating only, no runtime or security-sensitive code, and no CODEOWNER covers the changed files. Inline findings were already posted, so this note only records the extra consumers checked.

Review comments at @scripts/buildkite.ts:
- Line 438: Update the rename handling around the status-to-path return so a
`renamed` record without `previous_filename` is rejected rather than treated as
a single-path change. Ensure the incomplete record cannot reach the docs-only
skip decision, while preserving the existing behavior for renames with both
paths and non-renames.

[claude]

The follow-up push addresses the three points from my earlier pass (renamed-only previous_filename, line-array scan at the call sites, non-vacuous docs/ precondition), and I found no new bugs. A maintainer look is still worthwhile: this changes which pull requests get a Buildkite pipeline at all, and moves compiler-docs-links.test.ts from the required Buildkite check into the non-required Source lints lane, which is a CI policy choice rather than a correctness question.

What was reviewed:

• isDocsOnlyChange() is strictly narrower than the inline check it replaces (empty list still not docs-only; docs/lint/rules/ now excluded), and the renamed old path only ever adds entries, so the other consumers of allFiles (changedBakeInputs, SetupWebKit detection, modified-test prioritization) can only see more paths, never fewer; a stale old path is harmless in the test-prioritization sets since it matches no existing test.
• The moved test and the new one import only built-ins and relative scripts/ modules with no import-time side effects (agent.ts guards main() with import.meta.main), matching the bare-checkout constraint of the lane; no other reference to the old test/cli/ path remains.
• Not run here: the Source lints lane, the new test against main's scripts, or the stand-in ci.ts/runner.node.ts runs the description reports — those claims are the author's.

Extended reasoning...

The change is CI-only: a shared isDocsOnlyChange()/pullRequestFilePaths() pair in scripts/buildkite.ts used by .buildkite/ci.ts and scripts/runner.node.ts, a test file moved from test/cli to test/internal/source-lints with its duration entry removed, two added trigger paths in source-lints.yml, and a new source-lint test; nothing under src/ or packages/. It touches no security-sensitive surface. The second commit resolved every optional finding from the prior review and the predicate change only makes the skip rarer, which argues for approval; deferring instead because the move of a docs-link test out of the required Buildkite check and the stated downside that docs/compiler pages stay untested on docs-only PRs are policy trade-offs a maintainer should weigh, and the earlier coderabbitai inline comment's resolution cannot be confirmed from metadata.
