ci: convert the CI scripts to TypeScript and remove the ones CI does not run - #43595
Merged

Conversation
Pure renames, so history follows the files; the contents are converted in the commits that follow.
scripts/machine.ts keeps the Windows Packer bake and wait-image, typed. Everything else machine.mjs did (booting a machine in a cloud or VM and opening a shell on it, through azure.mjs, docker.mjs and tart.mjs, and the machine:* package scripts) is not used by CI and is removed, along with the files only it reached: .buildkite/Dockerfile, .buildkite/Dockerfile-bootstrap.sh and the Linux Packer template. The Windows Packer templates upload agent.ts and the utils.ts it imports instead of an esbuild bundle of agent.mjs.
The JSDoc types become real ones (strict, no any), with overloads where a helper's return type depends on its options (getEnv, getSecret, which), so callers get a string without a cast. Functions nothing reaches any more are deleted (the ssh, user-data and privileged-spawn helpers that only machine.mjs used, and rm, which had been a silent no-op), and helpers only this file uses are no longer exported. Typing turned up two references to names that do not exist: setEnv appended to an undeclared `outputPath` where the variable two lines up was meant, and getCloudMetadata used `inspect` without importing it. Both are fixed. Importers now import ./utils.ts; the ones that are already TypeScript lose their @ts-ignore.
Without it node guesses the module type of ci.ts from its syntax and warns on every run.
The pipeline's shapes become real types: Target and Platform, the agent a step asks for, retry rules, and Step as a union of the group, command and block steps this file emits. The generated pipeline is byte-identical for a normal commit and for a [build images] commit. Typing surfaced JSDoc that was wrong (getBuildAgent documented as returning a string, a JSDoc block sitting on the wrong function, fields declared but never emitted), which is corrected or dropped. An unreadable commit message is now an explicit error instead of a TypeError a few lines later.
The per-platform paths come from one typed function, with pidPath and cfgPath optional because only some platforms have them. No logic changes.
The vendored p-limit and yocto-queue are replaced by a small limiter in the runner, which covers the two places they were used: at most N functions at once, the rest start in order. Typing turned up calls that could only throw: server.off() without a listener, numbers passed as environment values (which also broke SHOW_SPAWN_COMMANDS), and Object.entries of an env that may be absent. Those are fixed; implicit coercions that change nothing are written out.
…eckout The pipeline's steps call runner.node.ts, machine.ts and agent.ts. The image bake installs the agent service with `node ./scripts/agent.ts install` from its own checkout: install now copies agent.ts and the utils.ts it imports into the agent's home on every platform (it only did on macOS), so the service does not depend on the checkout, and nothing has to put the script on the machine beforehand. Two one-line files keep names that are set outside a checkout working: .buildkite/ci.mjs, because the pipeline step's command is configured in the Buildkite UI for every branch at once, and scripts/runner.node.mjs, because the command hook installed on the macOS tart hosts recognises a test step by that name. The hook in the repo now matches either name. package.json's test scripts, the source-lints workflow's path filters and the source-lint test that reads the build matrix follow the renames.
…check in CI Mentions of ci.mjs, utils.mjs, agent.mjs, runner.node.mjs and features.mjs now name the .ts files, including scripts/darwin-ci's bare-mode provisioning, which runs the agent's install. .buildkite/bootstrap.yml is removed: nothing reads it, the pipeline step is configured in the Buildkite UI, and the copy had drifted from it. The Lint workflow typechecks scripts/tsconfig.json, so the CI scripts' types stay enforced.

✅ @dylan-conway, your commit b57937d9ca06d9e2e84ac5731fb7fbd8c23df60a passed in 🧪 To try this PR locally: bunx bun-pr 43595That installs a local version of the PR into your bun-43595 --bun |
scripts/build/ has had a strict tsconfig all along, but nothing ran it, and it had four errors: the two byte-class generators index their 16-entry tables with a computed number, which noUncheckedIndexedAccess types as possibly undefined. They now go through the build's assert(); the generated .h and .rs files are byte-identical. The Lint workflow runs tsc over both projects.
…ts accurate `$` had no caller left once machine.mjs went, and signAwsRequest is only used in this file. BuildkiteBuild lists the fields that are read, and getCloudMetadata's per-cloud paths are the two clouds that have one.
…ts and machine.ts
machine.ts derived the Windows image name itself and had to be kept in step
with getImageName() in ci.ts. The pipeline now passes the name it computed
(`bake-image --arch --name`), so it exists in one place.
- A platform key from a manual build's options step that this build does not
have (asan on main) is an error naming the key, instead of a pipeline full
of `undefined-undefined-build-bun`.
- The build steps drop --experimental-strip-types: every CI image has Node 26.
- machine.ts: the `|| default` after three getSecret() calls could not be
reached in CI, where a missing secret throws; the aws CLI gets only its
three variables again, as before.
- A comment lost a `$` ("$$ is a literal $").
…peScript; stale comments - agent.ts install writes a package.json next to the copy it installs. In the repo, scripts/package.json says these files are ES modules; the copy took its module type from whatever package.json sat above the agent's home (on macOS, the user's home directory), and a "type": "commonjs" there would stop the service from starting. The macOS token check now runs before anything is written. - features.ts drops its `// @bun` pragma, which hands the file to the engine untranspiled: fine for a .mjs, but a type annotation in the .ts would have been a syntax error. - Comments that still named the deleted Dockerfile, or said Node cannot import .ts, are corrected.
Going by what each script actually reaches in utils.ts: the cloud metadata, the AWS and Azure secret readers and the SigV4 signer are only the agent's; the canary revision, the YAML writer, the bootstrap version and the emoji table are only the pipeline generator's; unzip, the live output filter and a few more are only the test runner's; and parsing compiler output into annotations is only the build system's, so it becomes scripts/build/annotations.ts. The code is moved, not changed; the generated pipeline is byte-identical. The runner already had its own spawnSafe and stripAnsi, so the moved functions reach the shared ones under other names for now.
Only the agent's install used it, for four commands, each of which comes right after a write to a root-owned path (the init script, the systemd unit, the launchd plist). Install therefore only gets that far as root, where the option did nothing, so the sudo/doas probing behind it never mattered.
readFile, writeFile, mkdir and chmod wrapped the node:fs call of the same name to add a debug log line (readFile also cached files that are read once or twice). Their callers call node:fs. The agent, which writes six service and configuration files, keeps one small local writer that creates the directory and sets the mode; its homedir() was a bare passthrough and is gone.
…d buildkite.ts After moving out what only one script used, the rest of utils.ts was three things layered on each other, with no dependency pointing upwards: - process.ts: this process and the ones it starts (environment variables, the platform, spawn, which, the temp directory); - host.ts: what kind of machine this is (os, arch, abi, distro, kernel, hostname), which the agent reports as tags and the test runner checks; - buildkite.ts: the CI environment (what Buildkite and GitHub say about the build, secrets, meta-data, artifacts, annotations, log groups, curl). The code is moved as it was. Symbols are exported only where another file uses them, and scripts/build/ci.ts re-exports the six helpers it used to wrap in same-named constants. The agent now imports three files, so install copies agentFiles (agent.ts and what it imports) and the Packer templates upload the same four files from one scripts_dir variable. A source lint derives that list from agent.ts's imports and checks agentFiles and both templates against it.
spawn() resolved on the child's 'exit' event, which can come before its stdout and stderr have been read, so the result could be missing output the child wrote. With 60 children at a time each running `echo true`, 418 to 540 of 600 calls came back with empty stdout; resolving on 'close', which follows the streams, none do. The pipeline generator reads a manual build's options with many small `buildkite-agent meta-data get` calls at once.
…name The runner carried its own escapeHtml, escapeCodeBlock and unescapeGitHubAction, identical to the build system's, and its own stripAnsi, which only removed `ESC[<digits>m` and so left sequences such as `ESC[0;2m` in the text it parses. There is one of each now, in buildkite.ts. The runner's spawnSafe was a different function from the shared spawnSafe under the same name: it runs a process with timeouts and output handlers and never throws. It is spawnWithTimeout now, so the functions moved in from utils call the shared one without import aliases.
…on a retry did not fail spawn() and spawnSync() took timeout, stdin, retryOnError and a function form of throwOnError that no caller passes (retryOnError also made spawnSync's return type a promise-or-not union). They are gone, and spawnSafe is spawn plus throwing the error. curl() kept the error of a failed attempt after a later attempt succeeded, so a request that needed a retry was still reported as failed.
The agent imported three other files, so install copied a list of four, the Packer templates uploaded the same four, a lint kept the lists in step with the imports, and install wrote a package.json so the copies would load as ES modules. agent.ts now imports nothing but Node. What it used from the shared files it does directly: process.env, child_process for the service-manager commands and `buildkite-agent start`, fetch with a retry for the cloud's metadata and secret services, and a small PATH lookup (Node has none). Knowing what the machine is (os, arch, abi, distro, kernel, hostname) is the agent's, since it reports those as its tags, so host.ts is folded into it and the runner, buildkite.ts and ci.ts import it from there; agent.ts only runs main() when it is the entry point. install copies that one file into the agent's home as agent.mts, which is an ES module by its extension wherever it sits, and Packer uploads one file. The file list, its lint and the written package.json are gone. Host detection reports the same values as before on the machine this was written on, and the copy runs on its own under a package.json that says commonjs. The install and start paths themselves still need an image bake to be exercised.
A Node that can load the file but is older than 24.2 has no import.meta.main, so the entry-point check made the script do nothing and exit 0: a service that never starts an agent and is never restarted. The CI images pin 26.3.0; this is for a machine with an older node first on PATH. Two comments still described curl's options and imported files.
- getWindowsExitReason() looked for the Windows SDK's ntstatus.h under a relative path (a loop variable shadowed the directory it meant to join), so it has only ever returned undefined. Had it found the file, its unanchored match would have named exit code 1 after the first status containing 0x1. It and its three call sites are gone; nothing changes at run time. - startGroup() kept a lastGroup that was only assigned inside a branch that needed it set already. - curl() is what its callers use: a GET with json and cache. getSecret() had a redact option nothing passed. - ci.ts says so when the options step has no build-profiles, instead of a cast hiding the undefined; four types only annotations.ts uses are no longer exported.
…I script
process.ts had spawn(), spawnSafe() and spawnSync() returning an
{exitCode, signalCode, stdout, stderr, error} record of which callers read
stdout and error, a second copy of the platform constants and which(), a
getEnv() that 47 of its 56 callers told not to do anything, and a debugLog()
only the Windows image step switched on.
Every caller wanted one of two things, which agent.ts already had for itself
and now exports: output(command), what a command prints or undefined, and
run(command), a command on this process's stdio that throws unless it exits
with 0. The scripts also import the platform constants, which(),
requireCommand(), request() and tmpdir() from agent.ts, which is where what is
known about the machine lives. isBuildkite, isGithubAction, isCI and a getEnv()
that only throws are buildkite.ts's. An optional variable is read as
process.env.NAME.
Build meta-data is read and written one value at a time instead of ten at
once, which only a manual build's options step notices. machine.ts calls the
aws CLI through node directly, since it is the one place that replaces the
environment. scripts/tsconfig.json extends the build system's instead of
mirroring it.
…s and names scripts/build/ reads a typed object's fields with a dot and declares object types as interfaces; the converted scripts kept the JavaScript's options["cwd"] and used type aliases. They follow scripts/build/ now (keys that are not identifiers, such as "exec-path", keep their brackets). BuildKite in function names is Buildkite, as in isBuildkite and the file's name. scripts/build/ci.ts no longer re-exports six helpers, three of which nothing imported: build.ts imports the three it uses from buildkite.ts.
parseAnnotation() took a context no caller passed, formatAnnotationToHtml() took options no caller passed (with a concise form nothing asked for), a title is always set so the fallbacks after it could not run, and Annotation.url was neither produced nor read. The module is listed in the build system's inventory.
A test's result never carried the exit code, signal and duration that --results-json and the JUnit report read, so the report's times were all 0, and `bun install` steps passed a number of milliseconds to a parser of "1.2s" strings. The link of a failed test looked for the error's line in a field that was never set, next to the `errors` list that has it. Three destructured names nothing read are gone.
- curl() had the same loop as the agent's request() and was always asked for JSON: it is getJson(url), which adds GitHub's token and calls request(). A function named curl no longer sits above a real `curl` command. - getCommitMessage, getBranch, getMainBranch, isMainBranch and isMergeQueue took a cwd nothing passed. getFileUrl is always given a file and always returns a string, so the runner's url fields are strings. - setEnv()'s GITHUB_ENV branch could not run for either of its callers; they assign process.env. - The retry of a failed `buildkite-agent annotate` is a loop inside the function instead of an `attempt` field on its public argument.
…t os/arch - isAws, isGoogleCloud and isAzure each wrapped a nested function and a check of a cached cloud that their one caller, getCloud, had already made. They are three plain checks and getCloud asks them in order, once: start() passes the cloud to the metadata functions, which used to look it up again. - getCloudMetadata takes a path; the one caller with a path per cloud builds it. A missing token no longer becomes the placeholder "xxx": start() has already thrown by then. - getOs and getArch switch on process.platform and process.arch. They ran regexes over them, where /win/ also matches "darwin" and only the order of the branches kept that right. - One header, before the imports; cfgPath !== undefined says what isMacOS && cfgPath !== undefined said.
…optional parameters - The pipeline generator and the test runner each had the loop that pages through a pull request's files, with the response type declared twice. It is getPullRequestFiles() in buildkite.ts; a bad response throws in both callers now (the generator used to keep the pages it had). - The manual build's options step asks whether to force tests, and nothing read the answer. - getBootstrapVersion is always given the os, and a bootstrap script without a "# Version:" line is an error, not version 0. getRepository had one caller and branches for GitHub Actions, where this file never runs. parseBoolean takes the possibly missing value itself.
Thirteen comments said that a regular expression's group is not optional or that split() returns an element, next to the `!` that says it; scripts/build/ writes those bare. JSDoc blocks that only named their parameters are one line or gone, a result type still described exit codes as NTSTATUS names, escapeXml checked the type of a parameter typed string, and two comments in the build system's ci.ts compared it with a cmake build that no longer exists.
machine.mjs created machines in clouds and VMs and opened shells on them; what is left bakes the Windows CI image and waits for a Linux one.
They were closures inside doBuildkiteAgent(action, cliOptions), which looked up the agent and the paths for both and then dispatched on the action, and in which `command` meant the agent in one and node in the other. Each now names what it needs, and main() calls the one that was asked for. The service units, plists and configuration file are unchanged: every template literal in the file is byte-identical.
…node tests carry their result too `bun test` reports an error at the top frame of its stack, which can be in a helper, so the first error's line was not necessarily a line of the test file the link points to. It is used when the error's file is the test file. The node-compat tests, which are the ones the JUnit report is built from, now return the exit code, signal and duration as well. Expand-Archive runs on the job's stdio now, so its progress output is turned off.
…t; drop the force-tests question
- getPullRequestFiles() answers with no files when the build is not for a pull
request, instead of asking GitHub for pulls/false/files and logging the
error.
- The manual build's form asked whether to run the tests "even if no test
files have changed". Nothing skips tests for that reason, so the answer had
nothing to override; the question and the option are removed rather than
given a different meaning.
- getSecret(name, {}) requires the secret, as a missing options argument does.
describeImages reports why aws could not be started. Two doc comments sit on
the declarations they describe again.
A manual build whose options step has no build-profiles answer and no picked platforms builds the default pipeline, which never reads the profiles. The check had been made unconditional and failed that build.

Exercises the image bake with the TypeScript scripts: the Linux bake job's `node ./scripts/agent.ts install`, the Windows Packer bake through scripts/ci-image.ts, and the builds and tests that then run on the fresh images.

Every parameter of a GitHub workflow command is optional, the title too, and the title is only ever put in front of the message. parseAnnotations() threw on a command without one, so a single `::error file=a.ts,line=3::message` in a step's output discarded every annotation already parsed for it.
The previous bake build was cancelled by a push to the branch.

There was a problem hiding this comment.
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 checked the hand-written limiter that replaces the vendored p-limit in scripts/runner.node.ts (createLimit, ~line 690): a slot is handed to the next waiter in finally, so both resolve and reject paths release it and the running count cannot drift.
Extended reasoning...
Findings were already reported inline for scripts/buildkite.ts (lost page-1 results when a later GitHub files page fails), scripts/agent.ts (Node version floor raised by importing .ts from the .mjs shims; stderr of a failed buildkite-agent call dropped by output()). This note only records one additional concern that was examined and ruled out: the p-limit replacement at /home/claude/bun/scripts/runner.node.ts:690-708 keeps its slot count consistent because the slot is passed directly to the next queued waiter (or decremented) inside a finally, regardless of whether the wrapped test run resolved or rejected. The PR is a large CI-infrastructure refactor (70 files, ~8k added / ~13k removed) and the inline comments already signal that a human should look; this is informational only.

What
The scripts CI runs are TypeScript now, typed under the same strict settings as
scripts/build/, and the ones CI does not run are gone..buildkite/ci.mjs.buildkite/ci.tsscripts/utils.mjsscripts/agent.mjsscripts/agent.tsscripts/runner.node.mjsscripts/runner.node.tsscripts/features.mjsscripts/features.tsscripts/machine.mjs,azure.mjs,docker.mjs,tart.mjsscripts/ci-image.ts(only the two commands CI runs:bake-imageandwait-image)scripts/p-limit.mjs,scripts/yocto-queue.mjs(vendored)All but
features.ts, which the freshly built bun runs, run under plainnode(type stripping), so only erasable syntax is used, andscripts/tsconfig.jsoncovers them.The Lint workflow now runs
tsc --noEmitoverscripts/tsconfig.jsonand overscripts/build/tsconfig.json. Nothing typechecked the build system in CI before; it had four errors (the two byte-class generators index a 16-entry table with a computed number), which now go through the build'sassert(). The generated.hand.rsfiles are byte-identical.utils is dissolved
utils.mjswas a grab bag. By the time it was dissolved (converted, and with the helpers onlymachine.mjsused already gone), it exported 74 values: 9 imported by nothing, 38 by exactly one script, and 27 by two or more. Going by what each script actually reaches:agent.ts; the canary revision, the YAML writer, the bootstrap version and the emoji table intoci.ts; unzip, the live output filter and a few more into the runner; parsing compiler output into annotations into the build system, asscripts/build/annotations.ts.agent.ts, which reports it as the agent's tags: the platform, os, arch, abi, distro, kernel, hostname and temp directory, plus the few small helpers it needs for itself and now exports (output(command): what a command prints, or undefined;run(command): a command on this process's stdio that throws unless it exits with 0;which,requireCommand,request). What is known about the CI environment isscripts/buildkite.ts: what Buildkite and GitHub say about the build, secrets, meta-data, artifacts, annotations, log groups,getJson,getPullRequestFiles. An optional environment variable is read asprocess.env.NAME;getEnv(name)is for the ones that have to be set.spawn()/spawnSafe()/spawnSync()and their result record (every caller wantedoutputorrun), theprivilegedspawn option (only the agent's install used it, always right after writing a root-owned file, so the sudo/doas probing behind it never mattered), adebugLog()only the Windows image step switched on, four one-line wrappers overnode:fs,curl()options nothing passed (it isgetJson(url)on the agent'srequest()now, so there is one retry loop),cwdparameters nothing passed, parameters and branches of the annotation parser and formatter nothing reached, helpers nothing called, and two pieces that could not do anything:getWindowsExitReason(), which looked forntstatus.hunder a relative path and so only ever returnedundefined, and alastGroupinstartGroup()that was only assigned inside a branch that needed it set already.escapeHtml,escapeCodeBlockandunescapeGitHubAction, and its ownstripAnsithat only removedESC[<digits>m; there is one of each now. Its ownspawnSafe, a different function from the shared one under the same name, isspawnWithTimeout.The moves change no code; the generated pipeline is byte-identical across them. The converted code follows
scripts/build/'s style: dot access on typed objects,interfacefor object types, no comments that restate a!.scripts/tsconfig.jsonextends the build system's.Fixes that ride along, each in its own commit: the runner's results never carried the exit code, signal and duration that
--results-jsonand the JUnit report read (the report's times were all 0), and the link of a failed test never got its error's line (it does now, when the error is in the test file and not in a helper); the manual build's form asked whether to run tests "even if no test files have changed", which nothing ever decided on, so the question is gone; build meta-data is read and written one value at a time instead of ten at once (only a manual build's options step notices). Also:spawn()resolved on the child'sexit, which can come before its output has been read (with 60 children at a time runningecho true, 418 to 540 of 600 calls came back empty; resolving onclose, none do), andcurl()kept the error of a failed attempt after a later attempt succeeded.Conversions
No logic changes were intended in the conversions; JSDoc types became real types (no
any, no@ts-ignore), with overloads where a helper's return type depends on its options (getEnv,getSecret,which), so callers get astringwithout a cast.ci.ts:Target,Platform, the agent a step asks for, retry rules andStep(group, command and block steps) are typed. The generated pipeline is byte-identical to the oneci.mjsgenerated, for a normal commit and for a[build images]commit (checked by generating both before and after).ci-image.ts: the pipeline passes the Windows image name it computed (bake-image --arch --name), so the name is derived in one place instead of two that had to agree.features.tsdrops its// @bunpragma, which hands a file to the engine untranspiled: fine for a.mjs, a trap for a.ts.runner.node.ts,agent.ts: typed; the agent's per-platform paths come from one function.Typing turned up code that could only throw, which is fixed:
setEnvappended to an undeclaredoutputPath(the variable two lines up was meant),getCloudMetadatausedinspectwithout importing it, the runner calledserver.off()without a listener, passed numbers as environment values (which also brokeSHOW_SPAWN_COMMANDS) and tookObject.entriesof an env that may be absent. Wrong JSDoc (a return type, a block sitting on the wrong function, fields declared but never emitted) is corrected or dropped.Two small behaviour changes besides those: a platform key from a manual build's options step that the build does not have (asan on
main) is now an error naming the key, where it used to produce steps calledundefined-undefined-build-bun; and the build steps drop--experimental-strip-types, since every CI image has Node 26.Removed
machine.mjsdid besides the Windows Packer bake andwait-image: booting a machine in a cloud or VM and opening a shell on it (azure.mjs,docker.mjs,tart.mjs, the sixmachine:*package scripts), and the files only that reached (.buildkite/Dockerfile,.buildkite/Dockerfile-bootstrap.sh, the Linux Packer template). CI uses none of it..buildkite/bootstrap.yml: nothing reads it, the pipeline step is configured in the Buildkite UI, and the copy had drifted from it.agent.ts is the one file that runs on a CI machine
agent.tsimports nothing but Node: it usesprocess.env,child_process,fetchwith a retry for the cloud's metadata and secret services, and a small PATH lookup.installcopies that one file into the agent's home asagent.mts(an ES module by its extension, wherever it sits) on every platform (it only copied on macOS before) and registers the service against the copy. The Linux image bake runsnode ./scripts/agent.ts installfrom its own checkout instead of expecting the script to have been put on the machine beforehand, and the Windows Packer templates upload the one file instead of an esbuild bundle.Two one-line files
Two names are set outside a checkout, so each keeps a one-line file that imports the TypeScript one:
.buildkite/ci.mjs: the pipeline step's command is configured in the Buildkite UI, for every branch at once.scripts/runner.node.mjs: the command hook installed on the macOS tart hosts (scripts/darwin-ci/hooks/command.ts) recognises a test step by that name, so the macOS test steps keep calling it. The hook in the repo now matches either name; once the hosts have it, the steps can callrunner.node.tsand this file can go.Testing
tsc --noEmitover both projects: 0 errors.ci.tsconversion; after that, the only differences are the command lines that name the renamed scripts, the Windows image step's arguments, and the dropped--experimental-strip-types.bun test test/internal/runner-junit.test.ts test/internal/source-lints/ci-annotations.test.ts test/internal/source-lints/build-rust.test.ts test/internal/ci-slowest-tests.test.ts: pass.node, directly and throughrunner.node.mjs, and selects nothing for a filter that matches nothing.Not exercised yet: the image bake path (
agent.ts installon a fresh Linux box, the Windows Packer upload, the service starting fromagent.mts). That needs a[build images]run, which in turn needs the matching change on the CI provisioner side to be live first. This PR's own CI exercises everything else: pipeline generation, builds, and the test runner on every platform.
