Install cargo-llvm-cov 0.9.0 from the tool manifest - #470
Conversation
cargo 1.100 nightlies (from 2026-08-22) enable the new build-dir layout, which places test executables under debug/build/<package>/<hash>/out. cargo-llvm-cov 0.6.24 searched debug/deps and failed with "failed to collect object files" after every test had passed; statelet has reported exactly that since its toolchain moved to nightly-2026-08-23, and every repository reaches it on its next weekly toolchain bump. cargo-llvm-cov 0.9.0 reads the new layout (verified locally on statelet: 0.6.24 fails, 0.9.0 produces lcov on the same tree). Replace the cargo-binstall of 0.6.24 in generate-coverage and ratchet-coverage with a manifest-driven installer: it resolves the entry with the install-tool resolver, downloads the release archive, verifies its SHA-256 against .github/tool-manifest.toml (each digest recomputed from an independent download; upstream publishes no sidecars), extracts only the named member, and reuses an installed binary that already reports the pinned version. Tests hold the pinned version to the manifest for every supported runner, exercise download bounding, digest mismatch, missing member and reuse. The now-unused Ensure cargo-binstall step and its tests are removed, and cargo-binstall leaves the Cargo cache paths.

Reviewer's GuideBoth coverage actions now install cargo-llvm-cov 0.9.0 directly from the shared tool manifest, with platform-aware resolution, checksum- and archive-member verification, safe reuse and observability; generate-coverage no longer installs or caches cargo-binstall, and the change is backed by focused installer tests and updated documentation.

Merge Risk: 🔵 Low · up to The coverage actions now install verified cargo-llvm-cov archives instead of cargo-binstall. Merge risk is low, but the ADR should consistently describe the removed cargo-binstall cache and the migration checklist should comply with the repository’s Markdown style rule.

Review round on #470: resolve_tool no longer emits metrics and raises a typed ToolResolutionError that main turns into the bounded resolve metric; the installed-version check requires the exact expected line rather than a prefix, with a Hypothesis property holding that only that line counts as installed; the extracted binary is staged in a temporary directory beside the destination and published with a rename, so a concurrent reader cannot observe a partial executable even when TMPDIR and CARGO_HOME sit on different filesystems. Tests now drive main end to end against a temporary manifest served over a local HTTP server, cover a binary reporting another version on both the install and the reuse path, and the developers' and users' guides describe the manifest-driven installer in place of the removed cargo-binstall pinning.

The installers call the resolver directly, so they now fail closed on a manifest schema other than the one the resolver reads, as the install-tool action does, with a typed unsupported-schema kind and a test. The test helper _fake_tool loses an unused url parameter (CodeScene: five arguments where four is the ceiling).

A checksum-valid archive whose binary reports another version used to be published and only then rejected, replacing whatever was installed. The version probe now runs on the staged file, so a mismatch leaves the destination untouched; the test asserts the previous binary survives.

Review round three on #470. probe_version is now the one place a process is spawned to read a version and returns a VersionProbe over absent, unrunnable and reported; installed_at_pinned_version takes that value and the expected version and is pure; main publishes the probe outcome as a bounded cargo-llvm-cov.probe metric before deciding reuse. The Hypothesis property ranges over probe states as well as version strings, a parametrised test exercises each probe outcome against a real file, every test helper has a docstring, and the generate-coverage design document gains a dated decision superseding the cargo-binstall one and its addendum.

Review round four on #470. The test module loads the installer from generate-coverage and from ratchet-coverage in turn, so the ratchet copy is executed rather than assumed, and a test holds the two byte-identical. The developers' guide gains a usage example for probe_version and installed_at_pinned_version; the migration guide describes the move of cargo-llvm-cov to the tool manifest, its supported targets and the loss of cargo-binstall on PATH; ADR 0003 records the cache-path change in a dated addendum.

Withdraw Title check. The current title follows the verified local convention. PRs Withdraw Observability. The installer retains the established structured The test fixture parametrizes the installer suite over both action copies. The migration guide and ADR addendum contain the stated documentation. Runtime tests were not executed in this sandbox. I used the existing repository learnings for the installer-copy and observability contracts. 🧠 Learnings usedYou are interacting with an AI system. |

- Line 133: Update the earlier cache inventory for generate-coverage to remove
the cargo-binstall cache entry and path, keeping it consistent with the
addendum’s removal of ~/.cargo/bin/cargo-binstall.
In `@docs/migrating-to-verified-prebuilt-tools.md`:
- Around line 199-200: Update the checklist item around `cargo-binstall` and
`generate-coverage` to replace the second-person phrase “of yours” with “in a
later workflow step,” while preserving the installation guidance and avoiding
first- and second-person pronouns.

Review round five on #470. Action-level tests parse both coverage action manifests: exactly one Install cargo-llvm-cov step each, running the manifest-driven script; the generate-coverage one gated on Rust or mixed projects and not on nextest; no step provisioning or invoking cargo-binstall; the Cargo cache without its binary. Mutation-tested by re-adding an Ensure cargo-binstall step and by dropping the mixed condition, both caught. The ADR cache inventory now matches its addendum and the migration checklist loses its second-person wording.

cargo 1.100 nightlies (from 2026-08-22) enable Cargo's new build-dir layout, which places test executables under
