ci: build only the CLI product for CLI-only changes - #14212

Conversation
RFC #13519 audit class (d): 828 tests across 94 suites in cmuxTests spawn the bundled `cmux` CLI or another subprocess. They need the built product on disk; they do not need a live app host. Today they pay the app-host launch, the shielding window, and serialization with every other suite in the 477k-line bundle. This adds `cmuxCLITests`, a plain unit-test bundle with no TEST_HOST, and moves the first cleanly separable slice into it: 24 suites / 117 tests across 24 files, plus 13 shared helpers in a new `cmuxCLITestSupport/` directory that is a member of both test targets. - `cmuxCLITests/BundledCLITestSupport.swift` resolves the binary under test from `CMUX_CLI_PATH` first, then from the products directory beside the bundle, then from a `.app/Contents/Resources/bin/cmux` below it. That is what makes the bundle independent of an app host; the app-host copy is unchanged. - `CLIHookProcessRunner` owns the subprocess runner that used to be a static method on `CLINotifyProcessIntegrationRegressionTests`, so hook helpers shared by both bundles no longer name an app-host suite. - `CLITestBundleAnchor` gives the shared helpers a class to locate whichever bundle is running them. - New `cmux-cli-tests` scheme, built by `compile-app-host-test-product.sh` alongside the existing three, so the lane reuses the same compiled product artifact. `app_host_test_products.py` publishes its manifest as `CMUX_CLI_TESTS_XCTESTRUN` and no longer demands a product test host for a target the platform's own xctest agent loads. - New `cli-product-tests` job in ci-macos.yml on the Blacksmith macOS-15 pool. It restores the compile-admission product, points `CMUX_CLI_PATH` at the built CLI, and runs `-only-testing:cmuxCLITests` with no console session and no app-host isolation. `macos-status` requires it. Measured with the repo's own shard planner (`scripts/ci/cmux_unit_test_shard.py`, 6 shards, current reservations): shard before after 1 4.5 min 4.2 min 2 24.2 min 23.9 min 3 24.2 min 23.9 min 4 14.4 min 14.2 min 5 10.9 min 10.6 min 6 12.4 min 12.1 min total 90.6 min 89.0 min (-1.6 serial min, 2789 -> 2765 selectors) 12,619 lines also leave the app-host test bundle's compile unit. The rest of class (d) is blocked, not skipped. `CLINotifyProcessIntegration- RegressionTests` (144 tests) is extended from 33 files, three of which have open pull requests, and `CMUXCLIErrorOutputRegressionTests` (58 tests) owns `UnixSocketResponder` for nine more suites and is likewise in flight. Those clusters move in a follow-up once those land; the target and the lane are the part that had to exist first. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Two Linux guards enumerate what the macOS compile lane produces and who consumes it, so adding a fourth scheme and a fourth artifact consumer made both of them red: - tests/test_ci_product_publication.py asserted the exact set of jobs that read macos-compile-admission's artifact_id. cli-product-tests is a real consumer, and its `if` already satisfies the surrounding compile-only and reuse-products assertions, so it joins the set. - tests/test_ci_test_compilation_cache_seed.sh pinned the build to three schemes. compile-app-host-test-product.sh now builds cmux-cli-tests too, so the guard expects that scheme by name and counts four xcodebuild invocations.

…undle Merging main broke the app-host bundle's compile. #13427 added `GhosttyShellIntegrationTestResources` to RemoteShellCWDRelayTests.swift and called it from GhosttyConfigTests.swift; this branch had moved that file into cmuxCLITests. Rename detection applied main's edit to the moved file, so the definition landed in the CLI module while both callers stayed in cmuxTests: cmuxTests/GhosttyConfigTests.swift:5017: error: cannot find 'GhosttyShellIntegrationTestResources' in scope Both wiring guards pass on that state, because each file is wired correctly -- just to different targets. Only xcodebuild catches it. The test also does not belong in a bundled-CLI target. It never uses BundledCLITestSupport or CMUX_CLI_PATH; it writes its own fake `cmux` stub and drives /bin/zsh. Its resource lookup reads Bundle.main.resourceURL, which is cmux.app under the host and the xctest agent in a host-free bundle, and its fallback wants ghostty/src, which the CLI lane deliberately checks out without submodules. Moving it back fixes the compile and the resolution path together. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
An unwired .swift file under a test target is silently skipped: Xcode compiles nothing, and both xcodebuild and bot review report success. Until now one target existed, so lint-pbxproj-test-wiring.sh hardcoded cmuxTests and sync-test-wiring reconciled it. This branch adds a second bundle, which would have shipped 24 test files and 14 shared helpers outside that rule. The lint now takes --target and --tests-dir, both defaulting to cmuxTests, so existing callers are unchanged. Three invocations are added for the new bundle: cmuxCLITests/ against cmuxCLITests, and cmuxCLITestSupport/ against both bundles, since those helpers compile into each. Verified by dropping an unwired file into cmuxCLITests/ and watching the guard fail. sync-test-wiring still only reconciles cmuxTests; the lint now says so in its failure text instead of pointing at a tool that cannot fix the other target.

cmux_unit_test_shard.py balances the seven cmuxTests shards by measured time. 16 of the moved suites still carried weights totalling 89.4 s, so the planner reserved wall time on app-host shards for tests that now run in the CLI lane. Absent suites fall back to method-count estimates, so this only removes skew. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The compile script hardcoded four schemes, and nothing recorded which schemes a compiled product actually contained. That was fine while one producer built one thing, but it means a product built from fewer schemes would reuse under a full product's key, and a consumer would test something that was never built. PRODUCT_PROFILES in product_input_identity.py is now the single source of truth. The build script asks it for the scheme list instead of repeating one, so the built product and its identity cannot drift. The identity records the profile and its schemes, so two profiles over one revision produce different keys and neither answers the other's cache lookup -- including in github_product_identity, which recomputes under the consumer's own profile. app_host_test_products.manifests() requires exactly the profile's manifests, so a partial product is rejected at stamp time rather than at test time. No behaviour change: the profile defaults to app-host and its scheme list is the previous literal, in the same order. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
cmuxCLITests runs without an app host, but its product still came from macos-compile-admission, which builds cmux, cmux-unit, cmux-numeric-locale and cmux-cli-tests. #13795 routes cli-product-tests on `cli == 'true'`, so a change under CLI/ -- which classifies as macos=false, cli=true -- began paying a full macOS app build to run host-free CLI tests. Before that lane existed such a change triggered no macOS compile at all. cli-product-tests consumes exactly two things: the cmux-cli product and CMUX_CLI_TESTS_XCTESTRUN. The cmux-cli-tests scheme produces both, and cmux-cli has no target dependencies. CMUX_PRODUCT_PROFILE selects the scheme set per run: any macOS routing keeps the full product, because the app-host shards consume it and admission is also the check that proves the app compiles; purely CLI-routed changes build the one scheme their lane reads. It is declared once at workflow level so producer and consumer never disagree -- a mismatch would decline the artifact and cost a compile rather than reuse one.

The cmuxTests group gained RemoteShellCWDRelayTests here and three CloudDesktopOpen files on main; both sides are additive, so keep all four. Wiring is clean at 1006 files across all four target/directory pairs, and no symbol defined only in cmuxCLITests is referenced from cmuxTests. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Two conflicts, one textual and one semantic. The cmuxTests group gained RemoteShellCWDRelayTests here and three CloudDesktopOpen files on main; both sides are additive, so keep all four. #13854 landed canonical compile recipes whose test asserts the recipe makes exactly five xcodebuild calls: one version probe, one resolve, and one build per scheme -- three at the time it was written. This branch adds a fourth scheme, cmux-cli-tests, so the recipe now makes six calls and that assertion fails. Neither pull request is wrong and both were green alone; the count only breaks once they are combined. Derive the expectation from the recipe's scheme loop instead of pinning a total, and compare the built schemes to it. resolve() also passes -scheme (cmux-unit) next to -resolvePackageDependencies, so only invocations without that flag count as builds. Adding a fifth scheme now leaves the test passing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Add the node-local cache finalize step to cli-product-tests.
acquire creates a restore lease on cache hits and a fill token on cache misses. Without finalize, leases remain until expiration and restored products are not published to the node-local cache. This reduces cache reuse.

Add the parallel GitHub artifact transport before the single-stream fallback.
On full-suite routes, cli-product-tests uses the app-host profile. If the node and peer caches miss, this job uses the single-stream download directly. That path is documented as sustaining about 2 MB/s and taking 7–10 minutes per consumer. Add the parallel transport and gate the single-stream fallback on its hit output. Do not rely on the unsubstantiated 900 MB estimate.

…UUID test #13964 resolves a workspace ref from the parameterless workspace.list before scanning windows, so a live ref no longer needs window.list. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The errno-in-assertion lint and the quality-determinism route only scanned cmuxTests/, so suites moved into cmuxCLITests/ and helpers in cmuxCLITestSupport/ silently dropped out of both. Add the two directories to each, with a lint test and a routing test per path. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The CLI lane restored the compiled product like the app-host shards but skipped three of their steps. It now verifies a macos-* route landed on GitHub-hosted capacity before checkout, tries R2 and the parallel artifact transport before the single-stream download, and finalizes the node-local product cache with always(), so a miss no longer leaves a fill reservation for other consumers to wait out. The steps mirror app-host-unit-tests, minus its selective layer restore, which is app-host-profile-only. A contract test pins their order, the fall through guards, and the route check's equality with the app-host copy. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
An edit to cli-product-tests, to the admission job that builds its product, or to a script the lane runs left cli=false, so under the compile-only policy the lane that reads the change never ran. The job-by-job ci-macos.yml comparison now reports cli for those two jobs, an uncompared ci-macos.yml edit routes it too, and the lane's restore and run scripts are CLI lane inputs. A test checks every script the job names. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Eight fixtures copied the SO_NOSIGPIPE setup or the EINTR and short-write loop that CLIHookProcessRunner.swift already provides as ignoreSIGPIPE(onAcceptedFixtureSocket:) and writeAllToFixtureSocket(_:fd:).

Add the restore script's transitive helpers to CLI_LANE_EXACT_INPUTS.
The comment says that a change to a helper cli-product-tests reads must run the lane. The list names restore-app-host-test-product.sh. It does not name the helpers that script uses to validate and publish manifests.
The profile's scheme set comes from product_input_identity.profile_schemes(), and app_host_test_products.manifests() reads it. app_host_test_products.hosted_by_product() decides how the host-free manifest is validated.
Both files are in CI_MACOS_TEST_PRODUCT_INPUTS. A change to either file selects only macos=True. Under that route the profile is app-host, and cli-product-tests does not run. So a change to PRODUCT_PROFILES["cli"] or to hosted_by_product() merges without ever running the lane that consumes it.
test_cli_product_lane_scripts_route_the_cli_lane checks only scripts named directly in the job block, so it does not detect this gap.

The R2 restore step added to the CLI lane requests an OIDC token for the artifact broker, and the job had no id-token permission, so it always fell through to the slower transports. The contract test now requires the job's permissions to equal app-host-unit-tests'. Also routes the CLI lane for what its restore runs in turn: app_host_test_products.py, canonical-build-root.sh, and the download-test-product action.

Make product_input_identity importable when the test runs alone.
test_macos_compile_admission_precedes_expensive_shards imports product_input_identity from scripts/ci without local path setup. It depends on an earlier test mutating the process-wide path and can raise ModuleNotFoundError when run alone. Restore sys.path after the import.
Suggested fix
assert "build-for-testing" in compile_script
- import product_input_identity as identity
+ original_path = sys.path.copy()
+ try:
+ sys.path.insert(0, str(ROOT / "scripts/ci"))
+ import product_input_identity as identity
+ finally:
+ sys.path[:] = original_path📝 Committable suggestion

Correction to my measurement above. The 388 s to 36 s medians compare first admissions against reruns, so they aren't like for like. The one clean pair is #14325 with a seed hit: 120 s to 40 s compile (jobs 107891367186 and 107897749996), 80 s saved. 🤖 Generated with Claude Code |

cmuxCLITestsruns without an app host, but its product still comes frommacos-compile-admission, which buildscmux,cmux-unit,cmux-numeric-localeandcmux-cli-tests. Since #14211 (was #13795) routescli-product-testsoncli == 'true', a change underCLI/— which classifies asmacos=false, cli=true— now pays a full macOS app build to run host-free CLI tests. Before that lane existed, such a change triggered no macOS compile at all.cli-product-testsconsumes exactly two artifacts: thecmux-cliproduct ($products/cmux) andCMUX_CLI_TESTS_XCTESTRUN. Thecmux-cli-testsscheme produces both, andcmux-clihas no target dependencies.CMUX_PRODUCT_PROFILEnow selects the scheme set per run. A run builds the fullapp-hostproduct when it routes macOS and either nothing was admitted earlier or it runs the full suite orunit-ci(the app-host shards consume that product, and admission is the check that the app still compiles). Otherwise it builds thecliprofile, one scheme. That covers a purely CLI-routed change, and a mixed macOS+CLI change whose inputs an earlier run already admitted. App-host consumers only run underfull_suiteorunit_suite, which always selectsapp-host, so they never see the cli product: 4 schemes → 1.Also in this PR:
AgentNotifyCategorymoves out ofSources/AgentNotificationGate.swiftinto theCmuxSettingspackage (Values/AgentNotifyCategory.swift), madepublicandSendablesocmuxCLITestSupportcan use it without the app target. The move changes no behavior.Why this needed an identity change first
Nothing recorded which schemes a compiled product contained, so a product built from fewer schemes would reuse under a full product's key and a consumer would test something that was never built. That is a silently-wrong green, so the profile is part of the product's identity rather than a build flag:
PRODUCT_PROFILESinproduct_input_identity.pyis the single source of truth. The build script asks it for the scheme list instead of repeating one, so the built product and its identity cannot drift.github_product_identityrecomputes under the consumer's profile, so an app-host consumer declines a cli producer's receipt.app_host_test_products.manifests()requires exactly the profile's manifests — a partial product is rejected at stamp time, not at test time.The profile is declared once at workflow level so producer and consumer never disagree; a mismatch declines the artifact, which costs a compile rather than corrupting one.
Benefits and tradeoffs
CLI-only changes stop buying an app build, and the product's scheme coverage becomes explicit instead of implied by a literal in a shell loop.
The cost is a second product shape in the caches. The two profiles are disjoint by key, so they do not collide, but a repository that routes both will hold both. Landing this also changes
algorithm_fingerprint(), so existing exact-product reuse misses once.Validation
Local: the full Linux guard set passes (162 steps).
test_app_host_test_products,test_reuse_app_host_products,test_ci_change_areas,test_ci_product_publication,test_ci_cmux_unit_test_shard, and the compilation-seed and SPM-retry shell guards all pass. New coverage asserts that a cli-profile tree stamps with only its own manifest while the app-host profile still rejects the same tree as partial, and that every profile is distinguishable in the identity.I verified by reading the workflow that the only product consumers are
macos-compile-admission,app-host-unit-tests,tests-build-and-lagandcli-product-tests, and that both app-host consumers are gated oninputs.macos == 'true', so they never see the cheap profile.Verified in CI with the
cliprofile: fork proof run 35984674249 came from a CLI-only diff against this branch (macos=false, cli=true, teamleaderleo#97). Compile admission ran withCMUX_PRODUCT_PROFILE: cli, built onlycmux-cli-tests, and succeeded in under 10 minutes. The restored product containedCmuxAgentJournal_*_PackageProduct.framework, andcmux-cli-tests-build.logstayed within the Swift warning budget.CLI product teststhen restored that product and ran all 111 tests. On attempt 2, which rebuilt with thecliprofile, all 111 passed andmacOS statusandci-statuswent green. Attempt 1 had one failure on GitHub-hostedmacos-26:CLISSHPTYResizeInputTestshit its 5 s PTY-resize wait. That test also passes on this PR's upstream runs. The elapsed-time saving is still not benchmarked. This claims a scheme-count reduction.Restacked on #14211 at

CLI-only changes now build and run only the
cmux-cli-testsscheme instead of paying for a full macOS app build. This branch runs fromci/cli-lane-own-producerso CI gets repository variables and the macOS 26 pool, and it now sits directly on main with #14211 merged.What changed
PRODUCT_PROFILESinproduct_input_identity.pyis the single source of truth for a product's scheme set; the profile is part of the product identity, so a cli build keys separately and app-host consumers decline it, and mixed macOS+CLI changes build only the CLI scheme once admission passed.cli-product-testsinherits compile admission's runner, Xcode, and transport steps (route check, R2 and parallel artifact transport, node-local cache finalize), honorscliandunit_suiteinputs, forwards the built binary asTEST_RUNNER_CMUX_CLI_PATH, and mints the R2 transport's OIDC token.cli-product-tests, its admission job, or scripts the lane runs now routecli=true.CFFIXED_USER_HOMEpinned toHOME; shared subprocess and mock-server helpers keep a disconnected fixture client from killing the run.AgentNotifyCategorymoves into theCmuxSettingspackage; the wiring guard covers both new test directories but only lints CLI targets where they exist.Verified in CI with the
cliprofile on a CLI-only diff: compile admission built onlycmux-cli-testsin under 10 minutes and all 111 CLI tests passed.Written for commit 76c272b. Summary will update on new commits.
Summary by CodeRabbit
Moved from #13936, which was headed on the fork. Fork PRs get no repository variables, so their macOS jobs fell back to the macOS 15 pool. From this branch CI gets repo variables and the macOS 26 pool.
