CI: one workflow, planned lanes, toolchain images, and the JavaScriptCore tests - #645
CI: one workflow, planned lanes, toolchain images, and the JavaScriptCore tests#645dylan-conway wants to merge 58 commits into
Conversation
Nothing in CI ran a test. Add a `test` job that downloads the jsc shell shipped
by the bun-webkit-linux-{amd64,arm64}-asan lanes and runs
run-javascriptcore-tests (JSTests, LayoutTests/js, PerformanceTests) and testFFI
with it. The job does not gate the release and is continue-on-error until the
known failures on this fork are worked through.
Drop continue-on-error from the test job so a test failure turns the run red. The release still does not wait for the tests. The preview-build comment is now posted whenever the release was published rather than only when the whole build workflow succeeded, so it keeps appearing while tests are failing.

The 42 lanes were spread over seven near-identical jobs plus a hand-kept list of expected assets in the release job. They are now defined once, in .github/scripts/plan.mjs; a `plan` job turns that table into the build, test and expected-asset matrices. Every lane gets the same runner, release script and settings as before. The lanes that are tested build in their own job (same steps, via an anchor) so that the tests start when those lanes are done instead of waiting for all 42. Also drops the unused llvm_version input, and only triggers CI on pushes to main rather than starting a skipped run for every branch.
…usable.yml build.yml (pushes to main) and build-preview.yml (pull requests) were thin wrappers that called build-reusable.yml with a different commit, release tag and prerelease flag. They are now one workflow, ci.yml, with all three triggers: the plan job works out what is being built, and the pull request comment is a final job that only runs for pull requests. Tags, the write-access check for pull requests, manual dispatch with pr_number and the per-pull-request concurrency group are unchanged.
What differs between a build of main and a build of a pull request is now nine lines: the commit (env.REF), the release tag, the prerelease flag, the concurrency group and a one-line `gh pr comment` after publishing. The separate target-resolution step and the 60-line comment job are gone. Dropped: the explicit write-access check (a fork's token is read-only, so such a build already fails when it creates the release) and manual dispatch by pr_number. Manual dispatch now builds the head of the branch it is run on.
…r lane It was the one lane that still built on a Windows runner, because /MTd needs the static debug CRT (libcmtd.lib, libcpmtd.lib, libvcruntimed.lib) and an xwin splat has none for ARM64. The libs exist: for x64 they are in the same Visual Studio package as the release CRT, for ARM64 Microsoft ships them in a separate package, CRT.ARM64.Desktop.debug.base, that xwin does not select. Dockerfile.windows now fetches that package (pinned by sha256) and unpacks its libs next to the others. The lane takes the same settings as bun-webkit-windows-amd64-debug with WIN_ARCH=arm64. With it gone, the LLVM install and PowerShell steps are gone from the workflow: every lane is checkout, buildx, build, upload.
…e per lane Every one of the 42 lanes rebuilt its toolchain from scratch on every run: apt, the LLVM and GCC debs, the xwin download, the macOS SDK, the NDK. The Dockerfiles' `base` stages are now pure toolchain stages (no lane settings; the glibc and musl Dockerfiles get a `lane` stage on top for those), and CI keeps them as images in ghcr.io/oven-sh/bun-webkit-build-env, tagged with a hash of what goes into them. A new `image` job, one leg per distinct toolchain (10), builds and pushes an image only when its tag is missing, i.e. after a change to a `base` stage. Lanes start from their image (--build-context base=docker-image://...). If an image is not there a lane builds the toolchain itself, which is also what running a release script by hand still does. The ICU and WebKit stages are unchanged. Modelled on the bun-toolchain workflow in oven-sh/rust.
The image job warned and carried on when a push failed, and lanes fell back to building the toolchain themselves when their image was missing, so a broken registry setup would only show up as every lane being slow. Now the image leg fails, no lane starts, and a lane always builds from its image.
release.sh, musl-release.sh, macos-cross-release.sh, windows-cross-release.sh, freebsd-release.sh and android-release.sh were six copies of the same wrapper around `docker buildx build`, each also deriving a few settings that were visible nowhere else (MARCH_FLAG per architecture, WIN_TRIPLE_ARCH, ICU_MARCH_FLAG, ENABLE_MALLOC_HEAP_BREAKDOWN=ON for macOS Debug, FREEBSD_VERSION, ANDROID_API). What a lane was built with was spread over the plan, a script and the Dockerfile's defaults. .github/scripts/lanes.mjs (was plan.mjs) now holds every build argument of every lane and is the only way one is built: lanes.mjs build <label> --output <dir> [--base-image <ref>] lanes.mjs image <name> --push CI runs exactly that, so a lane can be reproduced by running the same command. For all 42 lanes the docker command is the same as the one the scripts on main produce: same Dockerfile, platform and build arguments.

.github/workflows/build-preview.yml—notifygates onneeds.build.result == 'success', and the reusable workflow's result now includes the newtestjob: whenever a JavaScriptCore test fails the called workflow's aggregate result isfailure, so the PR "Preview Builds" comment is never posted/updated even thoughreleasestill publishes the tarballs. On base every published preview got a comment; after this change any test flake hides an otherwise-good release from the PR. Fix: gatenotifyon the release having been published rather than the whole workflow succeeding, e.g.if: always() && needs.build.outputs.release_tag != ''(the reusable workflow already exports that output only on publish).Extended reasoning...
build-preview.yml calls build-reusable.yml as job
build. GitHub setsneeds.build.resultto the aggregate of every job inside the called workflow. This PR adds atestjob (build-reusable.yml:226-337) that runsrun-javascriptcore-tests --no-fail-fastand exits non-zero on any failing test. When that happens:release(which does not needtest) still runs, sees all builds succeeded, and publishes the draft (build-reusable.yml:381-385); but the reusable workflow's overall conclusion isfailurebecausetestfailed. Back in build-preview.yml,notifyhasneeds: [trigger, build]with noalways(), so it is skipped, and itsif: needs.build.result == 'success'would fail anyway. The preview release exists on GitHub but the PR comment linking to it is never created or updated. On the base branch there was notestjob, sonotifyfired for every published preview. The PR description says test failures are meant not to gate the release; this side-effect on the PR-comment path is not called out and leaves authors without the release link the workflow is meant to post.Verification: normal — The scenario is real and reachable.

- A tested lane that fails to build no longer skips the tests of the ones that did build: `test` runs whenever `build-tested` ran, and the leg of the lane that did not build fails at its download. - testFFI and run-javascriptcore-tests each run whatever the other did; either failing fails the job. Before, a testFFI failure skipped the JavaScriptCore tests, leaving no results or log. Also says what `native` means in lanes.mjs.

Preview build of 4b0d518: |
JSTests/wasm.yaml runs LayoutTests/imported/w3c/web-platform-tests/wasm/{core/js,jsapi}
with the harness in web-platform-tests/resources; the test job's sparse checkout
left them out and run-jsc-stress-tests died in `realpath` before running a test.
The log filter that drops "Skipping <test>" lines also dropped that error,
which was printed onto the end of one: it now only drops lines that are nothing
but a skip.
The glibc and musl Dockerfiles built for whatever architecture the container was, so the arm64 lanes needed arm64 runners and their own toolchain images. They now build in the same linux/amd64 container as the x86_64 lanes, with clang --target and a sysroot: - glibc: an ubuntu 20.04 arm64 sysroot (the arm64 ubuntu:20.04 image, focal's libc6/libc6-dev unpacked over it, and the arm64 half of the gcc-13 mirror), plus the aarch64 sanitizer runtimes from the arm64 half of the LLVM mirror. - musl: an alpine aarch64 sysroot populated by apk from the same repository. - ICU is a two-stage cross build for aarch64 (the container's own ICU tools live in the toolchain image), as in the FreeBSD and Android Dockerfiles. The x86_64 lanes run the same commands as before. The libc versions do not change, and that is now checked: the image build fails unless the sysroot's glibc is 2.31 like the container's (for musl: the same package version as the container's), and every glibc jsc that is linked must not need a symbol version newer than GLIBC_2.31. Every lane now builds on linux-x64-gh; arm64 runners only run tests. 8 toolchain images instead of 10. The musl stages no longer install packages or build zstd per lane: that moved into the toolchain image.
Every run queued one `image` leg per toolchain on the large runners only to find the image already there. `plan` (a standard runner, and it already knows the tags) now asks the registry itself and hands `image` only the missing ones; when there are none, `image` is skipped and the lanes start right after `plan`. The legs that do run, after a change to a Dockerfile's `base` stage, use a standard runner too: every image is linux/amd64 and building one is mostly downloading and unpacking. They free the usual disk space first. The registry token is passed to `docker login` through the environment rather than written into the script.
The toolchain images took the package installs, SDKs and sysroots out of the lanes, but every lane still fetched a few things and redid some lane-independent work: ICU's source tarball (all but macOS), its host tools (Windows, FreeBSD, Android), zstd, node and `patch` (Windows), and bootstrap_cmds to build `mig` (macOS). Those are now in each Dockerfile's `base` stage, so in the image. The stages on top only apply the lane's settings. On Windows the host ICU tools are therefore built from the sources before the udata.cpp hook patch is applied rather than after; the hook is null in ICU's own tools either way. The macOS image now depends on all of macos-cross/, not just xmac.mjs.
Each image leg used to delete the older versions of its own image as soon as it pushed a new one, on main only. That missed images nothing uses any more (a renamed toolchain, a pull request that never landed) and had no notion of age. A build of main now runs `prune`: every version of the package that main's lanes do not use and that was pushed more than 14 days ago is deleted, untagged leftovers included. An image a pull request pushed recently stays, so a toolchain change can be iterated on before it is merged; if an image a branch still wants has gone, `plan` finds it missing on that branch's next run and `image` rebuilds it.

Dockerfile.macos— nit: this comment still points readers atbuild-reusable.yml("Matches the native macOS lane's CMAKE_C_FLAGS (build-reusable.yml)"), which this PR deletes; after merge the reference is dangling and there is no native macOS lane in any workflow. Fix: update the comment to point at.github/scripts/lanes.mjs(ormac-release.bash) so future readers can find where these flags are kept in sync — this is the one remaining reference to the deleted workflow files across the repo.Extended reasoning...
A repo-wide grep for the deleted filenames (
build-reusable,release.sh,musl-release.sh,macos-cross-release.sh, etc.) turns up exactly one leftover: Dockerfile.macos:35 referencesbuild-reusable.yml. On the base branch that pointed at the CMAKE_C_FLAGS matrix in .github/workflows/build-reusable.yml; after this PR that file no longer exists and the flags live in .github/scripts/lanes.mjs (macos platformargs()) and mac-release.bash. Purely a documentation drift — no build behaviour is affected — but it is the sort of stale pointer that misleads the next person bumping DEFAULT_CFLAGS.Verification: nit — Dockerfile.macos:35 reads
# Matches the native macOS lane's CMAKE_C_FLAGS (build-reusable.yml) plus -g, and this PR deletes.github/workflows/build-reusable.yml(git diff --name-status showsD .github/workflows/build-reusable.yml; onlyci.ymlandmirror-llvm-debs.ymlremain in.github/workflows/). A repo-wide grep forbuild-reusablereturns only this one line, so the… | nit —…
…guments - A pull request from a fork gets a read-only token, so it could never publish, but nothing stopped its 42 lanes from occupying the large runners for an hour before failing at the upload (the old workflow refused such runs up front). `plan` is now skipped for them, and everything else needs `plan`. - A toolchain image's tag hashed its Dockerfile's `base` stage and the files it copies, but not the build arguments that stage takes from lanes.mjs (FREEBSD_VERSION, MACOS_DEPLOYMENT_TARGET, ANDROID_API, ...): bumping one left the tag unchanged and the lanes on the old toolchain. The ARGs a `base` stage declares that a lane sets are now part of the hash. - Dockerfile.macos: a comment still named the deleted build-reusable.yml.
…e builds - Creating the draft release was a job of its own next to `plan`. It is now the last step of `plan`, which already names the release. Every lane needs `plan`, so the draft exists before any lane starts, and the loop in which each lane waited up to ten minutes for it to appear is gone. - linux image: there are no *.list files in /etc/apt/sources.list.d in this container, so the glob handed to sed stayed literal and sed failed. - linux-musl image: /usr/share/apk/keys/aarch64/* are symlinks to ../<key>.pub, and cp -r copied them as dangling links, so apk trusted no key for the aarch64 index and found no packages. They are dereferenced now.
Builds: - aarch64 glibc sysroot: libc6-dev's libm.so, libpthread.so, libdl.so, ... are absolute symlinks into /lib/aarch64-linux-gnu, which dangle when the package is unpacked into a sysroot, so the linker quietly took the static archives. They are re-pointed into the sysroot, their presence is checked, and every glibc jsc must list libm.so.6 as NEEDED. - The glibc and musl version guards did nothing: under `set -e` a failing test that is not last in an `&&` list does not abort. They are separate statements. - The aarch64 sanitizer runtimes must be the version of the clang installed. Workflow: - prune: only on the first attempt of a push to main (a re-run of an old run knew an old set of images), and the two newest versions of each toolchain main has always stay, so the image main used until a moment ago is not pulled from under runs still in flight. - plan: a branch that predates lanes.mjs gets told so; a registry that cannot be asked is an error, not eight missing images; two images may not share a name; at least one lane must be tested and one not (no empty matrices). - test takes the jsc shell from an artifact of build-tested instead of the draft release, which `release` deletes the moment any lane fails. - A lane checks that there is a release to upload to before it builds, not after. - The image tag no longer changes with comments, lane-only ARG defaults or macos-cross/README.md. - Build and test checkouts skip about 2 GB nothing reads; dead outputs, ids and an API call left over from the reusable workflow are gone.
The `base` stage's LDFLAGS carry -L/usr/lib/x86_64-linux-gnu, where the distribution's ICU 66 lives (libxml2-dev brings libicu-dev), and that came ahead of the freshly built libicuuc.a: makeconv failed to link with undefined uprv_stricmp_78 and friends. The lanes' ICU step already replaces LDFLAGS for the same reason; the host tools step does now too.
`linux` sat next to `linux-musl` and `android`, which are Linux too; the job was called "image linux" though only the ten glibc lanes use it.
Dockerfile: TARGETARCH is always amd64, so the gcc-13 and LLVM bundles and their checksums are named directly, the library-path step is unconditional, and its `uname -m` twin (which did the same thing a second time) is gone. The LLVM symlink step ran twice, before and after the last apt-get install; the second run, whose result is the one that stands, stays. Dockerfile and Dockerfile.musl: CPU was an ARG and an ENV that no lane passes and nothing reads. musl never used LLVM_VERSION (clang-21 is spelled out). Dockerfile.freebsd, .android, .windows: the ICU_* ARGs in build_icu were only for the ADD that moved to `base`. Dockerfile.macos: two comments still spoke of native macOS lanes. No build argument, environment variable that is read, or command that affects an artifact changes.
Nothing runs them. CI builds every lane, macOS and Windows included, through lanes.mjs and the Dockerfiles; Bun builds WebKit from source with its own scripts/build.ts. Each of the three carried its own copy of the compiler flags and cmake options, already out of step with what ships (build.ts still looked for ICU under vcpkg_installed/), and a stale script that looks authoritative is how a wrong flag gets copied somewhere it matters. build-icu.ps1 stays: Bun runs it when it builds WebKit from source on Windows. It now says so.
… in its own task $vm.setHostTimeZone() bumps the time-zone generation; the VM drops its date and Intl caches when it is next entered (executeEntryScopeServicesOnEntry). The test read the zone back in the same task as the change and saw the old one. It now checks after a setTimeout, as the other setHostTimeZone tests do.
The ftl-eager-no-cjit mode passes --useExecutableAllocationFuzz=true --fireExecutableAllocationFuzzRandomly=true, which fails executable allocations at random. bun:ffi's call thunk, IC stub and callback thunk are allocated with JITCompilationCanFail and throw RangeError: Out of memory when that happens; unlike a JIT tier there is nothing to fall back to, so the tests failed on the exception. They opt out of the fuzzer the way wasm-loop-consistency.js does.

Beyond the inline finding, I also checked JSTests/stress/out-of-memory-while-creating-undefined-variable-error.js:13 for the same stale ReferenceError text — it still asserts "Can't find variable" (fallback is now "Variable is not defined"), but it is tagged //@ memoryHog! and CI passes --memory-limited, so it is skipped and will not fail the new test job.
Extended reasoning...
The confirmed finding flags a test the ReferenceError-text sweep missed. While tracing that sweep I looked at the other file that hard-codes the OOM fallback string: out-of-memory-while-creating-undefined-variable-error.js still compares against "Can't find variable", and under USE(BUN_JSC_ADDITIONS) the fallback at ExceptionHelpers.cpp:61 is "Variable is not defined". It does not affect the new CI job because the file is annotated //@ memoryHog! and ci.yml runs run-javascriptcore-tests with --memory-limited, which makes run-jsc-stress-tests skip every memoryHog! test. Noted here only so it is not re-raised as a CI failure; whether to update it for non---memory-limited local runs is up to the author.
This pull request has been reviewed before and this review found new issues. Where they share a root cause, one fix may close them together.

run-jsc-stress-tests keeps --quick and --no-slow in the same $mode and the later one wins, so on the macOS and Windows asan legs, which are --quick, adding --no-slow ran every mode. --quick already skips the tests marked slow!.

The asan and debug-asan lanes were built with bmalloc/libpas. Under ASan bmalloc hands every allocation to the system allocator at run time, so the only part of libpas those lanes ran was its JIT heap, which no shipped build has: release and lto are built with mimalloc, which leaves libpas out. With USE_SYSTEM_MALLOC=ON allocation is unchanged (ASan's malloc), libpas is not compiled, and the JIT pool is the allocator the shipped builds use, so the asan test lanes exercise that one. This also takes away the linux-arm64-asan failures in the ftl-no-cjit-small-pool mode: with a JIT pool under 256 MB every allocation goes to libpas's bitfit pages, and on Linux arm64, where the JIT small page is 64 KB, that page's 4128 byte header does not fit the utility heap's 1400 byte limit. lanes.mjs sets the argument per variant; the Dockerfiles pass it to CMake. The toolchain images are unchanged.
bmalloc has an #error for USE_SYSTEM_MALLOC on Windows (aligned memory cannot be freed via ::free), so that lane did not compile.
The pull request's head, built as the prerelease autobuild-1bd03678…: adds the sanitizer lanes built with USE_SYSTEM_MALLOC (no libpas) and the JSTests fixes. Still temporary until that pull request merges.
On Apple platforms run-javascriptcore-tests also runs testLibJSCTools, which the lanes do not build, like the other C++ test binaries; the macOS legs reported it as a failure.
On Linux under ASan JSC disables its wasm fault signal handler unless
ASAN_OPTIONS has allow_user_segv_handler=1 or handle_segv=0 (Options.cpp), and
without the handler a module with shared memory does not parse ("shared memory
is not enabled"): about 40 wasm tests failed on the asan lanes for that.
run-javascriptcore-tests takes it from perl, which on windows-11-arm reports x86_64, and passes it on as run-jsc-stress-tests --arch; the jsc.exe tested there is arm64.

🔴 Passing --architecture arm64 makes run-javascriptcore-tests die before any test runs on the Windows arm64 leg: on Strawberry Perl nativeArchitecture() hard-codes x86_64 (webkitdirs.pm:516/532 skip uname -m when isWindows()), so line 640 hits "arm64" ne "x86_64" && "x86_64" ne "arm64" and aborts with "Cannot run tests with arm64 on this machine" — every workflow run goes red with no arm64 coverage. Fix: make the perl driver see arm64 as native on Windows arm64 (teach determineNativeArchitecture to read $ENV{PROCESSOR_ARCHITECTURE}/PROCESSOR_ARCHITEW6432), or drop --architecture here and pass --arch straight to run-jsc-stress-tests via extra args.
Extended reasoning...
New since the last review. case "$LABEL" in *-arm64*) platform+=(--architecture arm64) is appended to the perl invocation for bun-webkit-windows-arm64-release on windows-11-arm. In run-javascriptcore-tests: GetOptions (line 408) sets $archs="arm64"; architecturesForProducts() (line 608) on non-Cocoa returns architecture(), whose determineArchitecture no longer finds --architecture in @ ARGV (already consumed) and falls back to nativeArchitecture([]) or CMake's CMAKE_SYSTEM_PROCESSOR (ARM64 upper-case on Windows) — neither contains lower-case arm64, so line 631 index($archsInBuild,$archs)==-1 dies with "arm64 not supported by the provided binary, which supports '…'". Even if that check passed, determineNativeArchitecture (webkitdirs.pm:515-532) does $output = uname -m unless isWindows() and then $output = "x86_64" if not defined, so nativeArchitecture($remotes) is always x86_64 under MSWin32 perl regardless of the host CPU; line 640 if ($archs ne native && native ne "arm64") { die "Cannot run tests with $archs on this machine" }…
Verification: normal — a newly-added test matrix leg that cannot ever pass, so every workflow run (main and PRs alike) goes red; the base branch had no test job. Trigger path: - .github/scripts/lanes.mjs:40 sets WINDOWS_ARM64 = "windows-11-arm" and :159-160 marks Windows arm64: { on: WINDOWS_ARM64, variants: ["release"], quick: true }, so plan emits a test leg for… | normal — the Windows arm64…
Summary
Nothing in CI runs a test today: every job builds and uploads. This adds a
testjob that runs JavaScriptCore's own suites with thejscshell the Linux asan lanes already ship, and restructures the build workflow around aplanjob so lanes are defined in one place.One workflow.
build.yml(main) andbuild-preview.yml(pull requests) were wrappers aroundbuild-reusable.yml. They are now a singleci.yml, and main and pull requests run exactly the same jobs. What differs is nine lines: the commit (env.REF, a pull request's head), the release tag (autobuild-<sha>vsautobuild-preview-pr-<n>-<sha8>, same names as before), the prerelease flag, the concurrency group, and a one-linegh pr comment --edit-lastafter publishing that replaces the 60-line comment script. Dropped: the explicit write-access check (a fork's token is read-only, so such a build already fails when it creates the release) and dispatch bypr_number; manual dispatch now builds the head of the branch it is run on, as a prerelease.Lanes from one table, built by one tool. The 42 lanes were seven near-identical jobs, a hand-kept list of expected assets in
release, and six*-release.shwrappers arounddocker buildx buildthat each derived a few settings visible nowhere else (MARCH_FLAGper arch,WIN_TRIPLE_ARCH,ENABLE_MALLOC_HEAP_BREAKDOWN=ONfor macOS Debug, ...)..github/scripts/lanes.mjsnow holds every lane: label, runner, Dockerfile, every build argument, tested or not.lanes.mjs planemits the matrices and the asset list;lanes.mjs build <label> --output <dir>builds a lane and is exactly what CI runs, so a lane can be reproduced by hand. The six scripts are deleted. Three workflow files totalling 973 lines become one of 421, test and image jobs included.Toolchain images. Every lane rebuilt its toolchain (apt, LLVM/GCC debs, xwin, macOS SDK, NDK) on every run. Each Dockerfile's
basestage is now a pure toolchain stage, kept as an image inghcr.io/oven-sh/bun-webkit-build-envtagged with a hash of what goes into it. A newimagejob (10 legs) builds and pushes an image only when its tag is missing; lanes start from theirs via--build-context base=docker-image://...and fall back to building the toolchain themselves if it is not there. ICU and WebKit stages are unchanged. Modelled onbun-toolchain.ymlin oven-sh/rust.Windows arm64 debug on Linux. The last lane that built on a Windows runner.
/MTdneeds the static debug CRT, which Microsoft ships for ARM64 in a separate package (CRT.ARM64.Desktop.debug.base) that xwin does not select;Dockerfile.windowsnow fetches it, pinned by sha256. Every lane is now the same four steps.Tests.
testruns onbun-webkit-linux-{amd64,arm64}-asan(Release + asserts + ASAN/UBSAN; plain Release compiles out$vmand the JIT disassembler). It downloads the tarball from the draft release, extractsbin/, runstestFFIandrun-javascriptcore-tests --no-fail-fast(JSTests, LayoutTests/js, PerformanceTests), lists failing files in the job summary and uploads the log and results JSON. The tested lanes build in their own job (build-tested, same steps via an anchor) becauseneeds:cannot name one matrix leg; that way tests start when those two lanes are done, not all 42.releasedoes not wait fortest.Also: drops the unused

testapi,testmasm,testb3,testair,testdfg), which the release Dockerfiles do not build, and test262.Test plan
Lane settings: ran the release scripts from
mainfor every lane, with the env the old workflow passes anddockerreplaced by a stub that records its arguments, and diffed that againstlanes.mjs build --dry-run: same Dockerfile, platform and build arguments for all 42 (windows-arm64-debugcompared against the cross script). Label set equals the old asset list. Dry-ran the tag and comment lines for main and for a pull request. Ran the build step's env export against a stub script for lanes with spaces, slashes and empty values. Test job: ran the same command with--quicklocally againstbun-webkit-linux-amd64-asan.tar.gzfromautobuild-28f58fb0. The workflow itself is first exercised by this PR's preview build.
