kevinveenbirkenbachandClaude Opus 5.5 078d0a0682 fix(lint): provision mmdc's browser only when it is missing
install-lint provisioned chrome-headless-shell on every run, and `make lint`
runs install-lint once per lint target in parallel whenever its stamp is not
fresh. On CI the stamp never is (eslint lives in node_modules, not on PATH),
so one lint job provisioned 16 times (run 38455552981). As root, puppeteer's
--install-deps runs `apt-get satisfy` even for an installed browser, and two
of those at once fail on the dpkg lock; a failed provisioning then deleted the
shared browser cache while lint-mermaid could be rendering with it.

The browser is now provisioned only when it is not installed, and --force
drops its cache so `make install-lint-force` still reinstalls it with its
libraries.

utils/install

This directory hosts the Python implementation behind make install-lint. For the general rules that govern READMEs in code directories see documentation.md.

Purpose

The package installs the lint toolchain (actionlint, shfmt, ruff, ansible-lint, mbake, markdownlint-cli2, eslint, shellcheck, ansible-playbook, ansible-galaxy) using the right channel per tool (system package manager, pip, npm, or GitHub release). Modules at this level are channel-agnostic primitives; per-tool policy lives one level down in lint/.

Structure

File Role
primitives.py Logging, sudo wrapping, PATH mutation, and stdlib-based URL download.
pip.py Venv-aware pip installer with --break-system-packages and --user fallback.
npm.py Global / local npm install with per-user --prefix fallback.
github_release.py Latest-tag resolver and asset downloader for GitHub releases.
system_pkg.py Per-manager dispatch for pacman / apt-get / dnf / yum / brew.
lint/ One module per tool, each exposing ensure(). See lint README.

The CLI entry point lives at __main__.py, invoked from lint.sh as python3 -m utils.install.lint. The matching dispatcher wrapper.sh routes make install-lint host vs container based on INFINITO_LINT_RUNNER.

File Naming

  • Module names MUST stay lowercase snake_case.
  • Channel-agnostic helpers MUST live directly under utils/install/.
  • Per-tool policy (one tool per file) MUST live under lint/ (see lint README).
  • Test files live in tests/unit/python/utils/install/ and mirror the module name with a test_ prefix.

Import Rules

  • primitives.py MUST NOT import from any other module in this package.
  • pip.py, npm.py, github_release.py, and system_pkg.py MAY import from primitives.py.
  • npm.py MAY import from system_pkg.py to bootstrap npm itself; no other cross-imports between these four are allowed.
  • Per-tool modules under lint/ MUST NOT import each other (see lint README).
