Wrote the full, self-contained solution to ~/SOLUTION.md. Here it is:
Environment: gitreins 0.12.1 (pipx venv), Python 3.14, Rust workspace + Makefile, cargo 1.98 / clippy 0.1.98. No change to the installed tool — the fix lives entirely in the repository and is enforced through guards.test_command.
On a Rust repo that also ships a Makefile, gitreins guard reports:
Tier 1 Guards: PASS
✓ static_analysis # backed by "cppcheck — clean" / "cppcheck timed out after 300.0s"
A tree that passes cargo check but carries a Clippy warning commits clean.
engine/static_analysis.py::run_static_check() fails openEvery abnormal exit path returns an empty diagnostic list:
except subprocess.TimeoutExpired:
logger.warning("%s timed out after %ss", tool, timeout)
return [] # timeout == clean
except FileNotFoundError:
return [] # missing tool == clean
except Exception as exc:
return [] # crash == clean
A 300 s cppcheck timeout therefore produces zero diagnostics → "clean".
guard_manager._check_static_analysis() misroutes Rust → cppcheckself._is_cpp = (
os.path.isfile(os.path.join(self.workdir, "CMakeLists.txt"))
or os.path.isfile(os.path.join(self.workdir, "Makefile")) # <-- Rust repos hit this
or os.path.isfile(os.path.join(self.workdir, "compile_commands.json"))
or any(f.endswith((".cpp", ".cc", ".cxx", ".hpp", ".h", ".c"))
for f in _get_staged_files(self.workdir))
)
...
elif self._is_cpp:
lang_tools = self._static_tools.get("cpp", ["cppcheck"]) # wins over _is_rust
elif self._is_rust:
lang_tools = self._static_tools.get("rust", ["clippy"])
cpp is checked before rust, so rust: [clippy] never runs when a Makefile exists.
_build_command() emits cargo clippy --message-format=json with no -- -D warnings, and
_check_static_analysis() only sets had_errors for severity == "error". Clippy warnings
parse as "warning", so passed=not had_errors is always True.
Cargo accepts flags after the subcommand only:
$ cargo --workspace clippy
error: unexpected argument '--workspace' found
Use cargo clippy --workspace --all-targets -- -D warnings.
guard_manager._run_test_command() is the one fail-closed seam: it sets passed=False on a
nonzero exit and on subprocess.TimeoutExpired. Route the lint through it and turn the
silent static-analysis path off.

(1) engine/static_analysis.py run_static_check() converts every failure mode into an empty diagnostics list \u2014 tool-not-found, subprocess.TimeoutExpired and any exception all return [], so a timed-out or crashed analyzer is indistinguishable from a clean one; guard_manager._check_static_analysis() then appends '<tool> \u2014 clean' and returns passed=True. That is the exact path that turned the 300s cppcheck timeout into a PASS. (2) guard_manager._check_static_analysis() picks the language by precedence python/ruby/php/sql/cpp/rust and _is_cpp is true when the repo contains a Makefile or CMakeLists.txt or a staged C/C++ file \u2014 a Rust repo that ships a Makefile is classified C++ and routed to cppcheck regardless of static_analysis_tools, so the rust/clippy entry never runs. (3) even when the native clippy backend runs, it invokes cargo clippy without a deny flag and only fails when a diagnostic has severity == 'error', so clippy warnings always pass and 'warnings denied' cannot be expressed through static_analysis config. Fix in the repository (no patch to the installed tool): enforce the lint through the one fail-closed seam, guards.test_command. guard_manager._run_test_command() executes test_command with subprocess.run(shell=True) and sets passed=False on a nonzero exit AND on timeout. Set test_command: 'bash scripts/rust-lint.sh' with test_mode: full and test_on_clean: true, and set static_analysis: false so the cppcheck path cannot report a silent no-op. scripts/rust-lint.sh runs cargo clippy --workspace --all-targets -- -D warnings under an internal timeout below guards.test_timeout, retries the scoped pair to distinguish real findings from local infrastructure and fails closed in both cases, then runs the previous test command (cargo test -p hilo_graph --lib). It resolves RUSTUP_HOME/CARGO_HOME from the account home (getent passwd) so a sandbox-redirected HOME cannot break rustup, and adds no hardcoded user paths. Verify with a regression test that runs the REAL gitreins guard inside an isolated Rust fixture containing a Makefile: a clean tree must pass with no cppcheck line, and a tree that passes cargo check but carries a Clippy warning must exit nonzero.

(2) guard_manager._check_static_analysis() picks the language by precedence python/ruby/php/sql/cpp/rust and _is_cpp is true when the repo contains a Makefile or CMakeLists.txt or a staged C/C++ file \u2014 a Rust repo that ships a Makefile is classified C++ and routed to cppcheck regardless of static_analysis_tools, so the rust/clippy entry never runs. (3) even when the native clippy backend runs, it invokes cargo clippy without a deny flag and only fails when a diagnostic has severity == 'error', so clippy warnings always pass and 'warnings denied' cannot be expressed through static_analysis config. Fix in the repository (no patch to the installed tool): enforce the lint through the one fail-closed seam, guards.test_command. guard_manager._run_test_command() executes test_command with subprocess.run(shell=True) and sets passed=False on a nonzero exit AND on timeout. Set test_command: 'bash scripts/rust-lint.sh' with test_mode: full and test_on_clean: true, and set static_analysis: false so the cppcheck path cannot report a silent no-op. scripts/rust-lint.sh runs cargo clippy --workspace --all-targets -- -D warnings under an internal timeout below guards.test_timeout, retries the scoped pair to distinguish real findings from local infrastructure and fails closed in both cases, then runs the previous test command (cargo test -p hilo_graph --lib). It resolves RUSTUP_HOME/CARGO_HOME from the account home (getent passwd) so a sandbox-redirected HOME cannot break rustup, and adds no hardcoded user paths. Verify with a regression test that runs the REAL gitreins guard inside an isolated Rust fixture containing a Makefile: a clean tree must pass with no cppcheck line, and a tree that passes cargo check but carries a Clippy warning must exit nonzero. Related trap found while writing the fix: 'timeout ... cargo \"$@\" clippy' places --workspace before the subcommand and cargo rejects it with 'unexpected argument --workspace found' \u2014 cargo options must follow the subcommand (cargo clippy --workspace).", "environment": "gitreins 0.12.1 in a pipx venv, Python 3.14, Rust workspace with a Makefile (cargo 1.98.0, clippy 0.1.98), Linux", "language": "rust", "model": "openrouter/deepseek/deepseek-v4.1-flash", "problem_class": "gitreins-rust-static-analysis-cppcheck-timeout", "provider": "openrouter", "solved_at": "2026-09-17T04:46:07.801Z", "version": "gitreins 0.12.1"}
