The comment above MIMALLOC_OVERRIDE_DEFINE claimed Unix "relies on static-link-order override". That was never true. mimalloc emits strong malloc/free definitions only when MI_MALLOC_OVERRIDE is set — the define its source gates alloc-override.c on — and the build set it for MinGW only. MI_OVERRIDE, which the build does set everywhere, is this project's own prod/test marker that mimalloc never reads. With the override body compiled out there were no strong symbols for link order to prefer, so ordinary malloc went to libc. Measured, not inferred. The shipped v0.9.1-rc.1 artifacts report 0/6 allocator-owned size classes on linux-arm64 glibc AND musl-static, and the same A/B on ubuntu-arm64 here: main warn mem.allocator.not_owned owned_classes=0/6 with this fix info mem.allocator.owned classes=all Every purge/reclaim option cbm_mem_init sets was therefore inert on Linux, applying only to the bound sqlite/tree-sitter populations — the same class of defect as #581, where committed memory ratcheted for months because nothing asserted the wiring on a real artifact. macOS stays off deliberately and permanently: enabling the override there compiles alloc-override.c's forwarding definitions, and under the two-level namespace this binary's free becomes mi_free while system libraries keep allocating from the system allocator, so the first pointer crossing that boundary aborts with "mi_free: invalid pointer". ELF's flat namespace has no such split, which is why Linux can have this and macOS cannot. Three parts: * Makefile.cbm switches MI_MALLOC_OVERRIDE and a new CBM_MEM_GLOBAL_OVERRIDE together in one place, for MinGW and Linux. The latter tells our own sources what to expect and goes into CFLAGS_PROD only, because MIMALLOC_CFLAGS_TEST builds mimalloc with -DMI_OVERRIDE=0 and no override define: a test binary has no global override BY CONSTRUCTION and must never be told to expect one. Deriving that expectation from the platform instead would make every Linux test run warn about a correctly configured build. * mem.c splits the startup audit by what the build actually asked for. Where no override was requested, ordinary malloc reaching libc is the design, so it reports the measured ownership at INFO and names what IS bound. A warning that fires on every run of a correct build is not a tripwire, it is noise — it trains readers to ignore the one line that catches #581. The genuine warning still fires wherever an override was requested and did not take. * smoke-test.sh Phase 1b pins the SHIPPED artifact's wiring per platform and fails in BOTH directions: Windows/Linux must own all classes, macOS must not. This cannot live in a unit test — a from-source test build never has the override — which is exactly why the defect survived so long. Verified on ubuntu-arm64: prod owns all classes; the test build reports bound-populations-only at INFO (0/6) and the mem suite stays green; smoke Phase 1b passes, and fails with the expected message when the same tree is built with the override forced off. On macOS: prod reports bound_populations_only at INFO, smoke Phase 1b passes, mem suite 51/51. Signed-off-by: Martin Vogel <martin.vogel.tech@gmail.com>
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.
