Windows already handed updating to install.ps1, because a running .exe cannot
replace its own image. The remaining platforms now do the same, for a different
and better reason.
An in-process updater is structurally a downloader: it fetches a remote archive,
verifies it, extracts it, marks the result executable and runs it. That composite
lived in every shipped artifact -- along with the release URLs it fetched -- to
serve a command most users run a handful of times. The install scripts already
do all of it, are idempotent (so re-running one IS the update), and run while cbm
is not running.
`update` now prints the exact command for the running platform and exits 0:
unix bash "<dir>/install.sh" (or the curl one-liner when not adjacent)
windows powershell -ExecutionPolicy Bypass -File "<dir>\install.ps1"
Both scripts ship inside their release archive, so the printed path resolves
next to the binary. Flags are still parsed and validated, so `update --dry-run
--ui` keeps rejecting typos rather than silently accepting them.
The updater itself is EXCLUDED from release builds rather than left to dead-code
elimination: build_update_url, download_verify_install, extract_and_install_binary,
checksum fetch, detect_os/detect_arch and the cli_download_* helpers now compile
only under CBM_CLI_ENABLE_TEST_API, which release builds do not define. The C
suite still covers the flow through the activation test seam. Verified against
the release binary: `releases/latest/download` is gone entirely.
Also removes the MCP background update check. It ran on the first tool call and
did:
cbm_popen("curl -sf --max-time 5 -H 'Accept: application/vnd.github+json' "
"'https://api.github.com/repos/.../releases/latest' 2>/dev/null")
An embedded shell command plus a startup network callout, in every session, to
tell users a newer version exists. It shelled out, depended on curl being
installed, and phoned home from every agent session. The install scripts report
versions; this did not need to be in the server.
Smoke follows the same collapse. Phases 6c and 14 asserted a Windows-specific
handoff and a POSIX in-process replacement; they now assert one platform-neutral
contract selected by UPDATE_SCRIPT, and 14a's byte-identity check compares the
driver against ITSELF before and after -- comparing against "$BINARY" passed on
Windows only because Windows has no signing step, while the POSIX fixture
ad-hoc re-signs its copy and so differed before `update` ever ran.
The Linux glibc guard is RELOCATED, not retired. The standard linux asset links
glibc 2.38+ and breaks Debian 11, RHEL 8 and Ubuntu 20.04, so the installer must
fetch the static "-portable" build. That constraint moved from the binary to
install.sh, and the smoke now guards it where the behaviour lives.

scripts/ — the canonical leg entries
The doctrine (enforced, not advisory): a venue may provision a machine;
only a canonical leg script may exercise the product. Local CI, PR CI, the
dry run and the release all call the SAME files below — venues differ only in
host specs, architecture and inputs, never in what a leg does. Platform
differences (arm64 sanitizer flags, the Windows launcher, the linux portable
binary) live INSIDE these scripts, once, never per-venue.
tests/test_venue_parity_contract.sh (run as Step 0j of every test leg) turns
any violation — inline harness logic in a workflow, a bypassed wrapper, a
missing --help — into a red build.
Every entry answers --help (authoritative, agent-oriented: modes, env, exit
codes) and rejects unknown flags with exit 2 + Please consult --help.
The legs
| leg | entry | what a run gives you |
|---|---|---|
| test | test.sh |
DEFAULT = the venue leg: static contracts (Step 0a–0j) + CLEAN ASan+UBSan build + all suites via the parallel harness + prod-binary guards. --suites a,b = iteration mode (incremental rebuild, subset, seconds). --tsan = the ThreadSanitizer leg. CLANGARM64 gets CI's trap-UBSan flags automatically. |
| build | build.sh |
CLEAN production build (+ launcher on Windows). ccache via env.sh makes repeats fast; CCACHE_COMPILERCHECK=content guarantees a hit is byte-identical to a cold compile — never stale. --with-ui, --version, STATIC=1, BUILD_DIR=. |
| lint | lint.sh |
clang-tidy + cppcheck + clang-format (+ no-skips policy). --ci = the CI gate set (no clang-tidy). Drives the same make targets as make lint/lint-ci. |
| smoke (unix) | smoke-local.sh |
Stages a full release fixture, serves it on a kernel-assigned port, runs smoke-test.sh (ALL phases incl. download/install/update E2E) inside a disposable HOME/XDG/TMP sandbox. ui variant makes a missing embedded UI a FAILURE. CBM_SMOKE_ARTIFACT_DIR = smoke an extracted release artifact verbatim (release mode). |
| smoke (windows) | ../test-infrastructure/vm/vm-smoke.sh |
Same contract for the launcher+payload pair, plus the user-PATH registry guard (prepare/verify/cleanup). |
| smoke-invariants | smoke-invariants.sh |
The "shipped binary does not fail" battery (MCP handshake, all tools invocable, malformed-input resilience) — no fixture server, no install E2E. smoke.yml runs it on the WIDEST build-from-source matrix (incl. older-glibc legs the release artifacts cannot cover). |
| soak | soak-legs.sh |
The release-gating soak SEQUENCE: quick then query-leak (the #581 detector — never reindexes, so RSS growth = query-path leak), each guarded by a completion-summary check. --legs quick for the ASan single-leg variant. Duration is per leg. |
Internal harnesses — never called directly by a venue (the contract forbids
it): smoke-test.sh (phases; wrappers provide fixture server + sandbox),
soak-test.sh (one soak run; soak-legs.sh provides the sequence + guards),
run-tests-parallel.sh (reached through test.sh).
Conventions
- Exit codes: 0 = pass · 2 = usage error · 90 = guard (a run died without its completion summary — never counts as green) · anything else = the leg's real failure.
- Iteration is a flag, not a side-tool: the fast paths (
--suites,--legs) are modes of the SAME entry the gates run, so a dev loop can never drift from the venue behaviour. - Env sandboxing: the smoke wrappers neutralize every agent-config destination override; a smoke can never scribble on your real config.
Recommended workflows
- Iterating on a change:
scripts/test.sh --suites <suite>(seconds, incremental, same ASan+UBSan flags as the gate). List suites:build/c/test-runner --list-suites. Debugging a Windows-on-ARM trap: re-run withSANITIZE=for a plain build, or use the emulatedwin.sh ubsan-*pair for full diagnostics. - Before any push (the 3-OS ladder):
scripts/test.sh(macOS, full) →./test-infrastructure/run.sh full(Linux + TSan + smoke) →test-infrastructure/vm/win.sh test-par+guards+smoke-install(+soakwhen the change touches memory/daemon paths). - Concurrency-touching change: add
scripts/test.sh --tsanearly — the same leg CI gates on. - Release-shaped verification:
CBM_SMOKE_ARTIFACT_DIR=<extracted artifact> scripts/smoke-local.sh <binary> [ui]smokes exactly what would ship. - A leg is red in CI but green locally: first suspect environment shape,
not code — the preflights (
win.shautomatic;scripts/ci/preflight-docker.sh) andtest-infrastructure/README.md's residuals list cover the knowable differences.
