Run Pre-commit Checks

This skill guides you through running the mandatory pre-commit verification script for the Torrust Tracker Deployer project.

⚠️ Critical Rule

Before committing ANY changes, you MUST run the pre-commit verification script:

./scripts/pre-commit.sh

All checks must pass before staging files with git add or creating commits with git commit. This applies to any method of committing:

  • Terminal: git add, git commit, git commit -am, cd ../ && git add ...
  • VS Code: Git panel, Source Control view, commit shortcuts
  • IDEs: IntelliJ, CLion, RustRover git integration
  • Git clients: GitHub Desktop, GitKraken, etc.
  • CI/CD: Any automated commits or merges

When to Use Pre-commit Checks

Run the pre-commit script:

  • ✅ Before every commit (mandatory) - Regardless of how you commit
  • ✅ After making any code changes - Verify quality standards
  • ✅ Before pushing to remote - Ensure CI will pass
  • ✅ After resolving merge conflicts - Verify integrity
  • ✅ When preparing a pull request - Final verification

What the Script Checks

The pre-commit script runs comprehensive quality gates:

Standard Mode (Full Checks)

When running without environment variables, executes all checks:

  1. Unused Dependencies: cargo machete

    • Detects and reports unused dependencies in Cargo.toml
    • Zero unused dependencies required

  2. All Linters: cargo run --bin linter all

    • Markdown linting (markdownlint)
    • YAML linting (yamllint)
    • TOML formatting and linting (taplo)
    • Spell checking (cspell)
    • Rust code analysis (clippy on stable & nightly)
    • Rust code formatting (rustfmt)
    • Shell script analysis (shellcheck)

  3. Unit Tests: cargo test

    • All unit and integration tests must pass

  4. Documentation Build: cargo doc --no-deps --bins --examples --workspace --all-features

    • Verifies documentation compiles without errors

  5. E2E Infrastructure Lifecycle Tests: cargo run --bin e2e-infrastructure-lifecycle-tests

    • Tests infrastructure provisioning and destruction (~44 seconds)

  6. E2E Deployment Workflow Tests: cargo run --bin e2e-deployment-workflow-tests

    • Tests software installation, configuration, release, and run (~48 seconds)

Total execution time: 5-10 minutes (depends on machine performance)

⚠️ Important for AI Agents

If you are an AI agent executing this script programmatically:

  • Set command timeout to at least 10 minutes (600 seconds)
  • The script takes 5+ minutes even on powerful development machines
  • Many AI agent environments have default timeouts of 180 seconds (3 minutes), which is too short
  • Prematurely terminating the script will result in incomplete validation
  • Consider using Fast Mode for quicker feedback within timeout constraints

Fast Mode (Skip Slow Tests)

For faster feedback during development or when working within time constraints (e.g., GitHub Copilot's 5-minute timeout):

TORRUST_TD_SKIP_SLOW_TESTS=true ./scripts/pre-commit.sh

This mode skips:

  • E2E infrastructure lifecycle tests (~44 seconds)
  • E2E deployment workflow tests (~48 seconds)

Fast mode still runs:

  • Unused dependency check
  • All linters (comprehensive check)
  • Unit tests
  • Documentation build

Total execution time: Approximately 2 minutes 30 seconds

Important: Skipped tests will run automatically in CI after PR creation. Use fast mode only when:

  • Working interactively with AI agents (timeout constraints)
  • Rapid iteration during development
  • You've verified E2E tests pass locally in a previous run

Usage Workflows

Workflow 1: Standard Pre-commit (Recommended)

# 1. Make your changes
# ... edit files ...

# 2. Run pre-commit checks (MANDATORY)
./scripts/pre-commit.sh

# 3. If all checks pass, stage and commit
git add <files>
git commit -m "feat: [#42] add new feature"

# 4. Push to remote
git push

For AI agents: When running programmatically, ensure command timeout is set to at least 600 seconds (10 minutes).

Workflow 2: Fast Pre-commit (Time-Constrained)

# 1. Make your changes
# ... edit files ...

# 2. Run pre-commit checks in fast mode
TORRUST_TD_SKIP_SLOW_TESTS=true ./scripts/pre-commit.sh

# 3. If all checks pass, stage and commit
git add <files>
git commit -m "feat: [#42] add new feature"

# 4. Push to remote (E2E tests will run in CI)
git push

Workflow 3: Fixing Failures

# 1. Run pre-commit checks
./scripts/pre-commit.sh

# 2. If a check fails, read the error output carefully

# 3. Fix the specific issue (examples follow)

# 4. Re-run the pre-commit script
./scripts/pre-commit.sh

# 5. Repeat until all checks pass

Common Failure Scenarios

Unused Dependencies Detected

FAILED: Unused dependencies detected by cargo machete

Fix:

  1. Read the cargo machete output to see which dependencies are unused
  2. Remove unused dependencies from Cargo.toml
  3. Run cargo build to verify the project still compiles
  4. Re-run ./scripts/pre-commit.sh

Linter Failures

FAILED: Linters found issues

Fix:

  1. Identify which linter failed from the output

  2. Run the specific linter to see detailed errors:

    cargo run --bin linter markdown   # Or yaml, toml, cspell, clippy, rustfmt, shellcheck

  3. Fix the reported issues

  4. Re-run ./scripts/pre-commit.sh

Common linter fixes:

  • rustfmt: Run cargo run --bin linter rustfmt to auto-format
  • clippy: Address code quality warnings
  • markdown: Fix markdown formatting (line length, lists, etc.)
  • cspell: Add unknown words to project-words.txt or fix typos

Test Failures

FAILED: Some tests failed

Fix:

  1. Run tests to see which ones failed:

    cargo test

  2. Read the test failure output carefully

  3. Fix the failing tests or the code causing the failure

  4. Run cargo test again to verify

  5. Re-run ./scripts/pre-commit.sh

Documentation Build Failures

FAILED: Documentation build failed

Fix:

  1. Check the error output for broken documentation links or invalid syntax
  2. Fix documentation comments in your Rust code
  3. Run cargo doc to verify
  4. Re-run ./scripts/pre-commit.sh

E2E Test Failures

FAILED: E2E tests failed

Fix:

  1. Read the E2E test output carefully
  2. Check if it's a real failure or an expected behavior (see docs/contributing/known-issues.md)
  3. If it's a real failure:
    • Fix the code causing the failure
    • Run the specific E2E test: cargo run --bin e2e-infrastructure-lifecycle-tests or cargo run --bin e2e-deployment-workflow-tests
  4. Re-run ./scripts/pre-commit.sh

Note: Some E2E test output appears red but is expected (e.g., SSH host key warnings). See docs/contributing/known-issues.md.

Troubleshooting

Script Takes Too Long

If the full pre-commit script is taking too long:

  1. Use fast mode: TORRUST_TD_SKIP_SLOW_TESTS=true ./scripts/pre-commit.sh

  2. Run checks individually during development:

    cargo run --bin linter clippy    # Quick Rust checks
cargo run --bin linter rustfmt   # Quick formatting
cargo test                       # Quick unit tests

  3. Run full pre-commit only before final commit

Environment Issues

If you encounter environment-related issues:

  1. Check dependencies: cargo run --bin dependency-installer check
  2. Install missing tools: cargo run --bin dependency-installer install
  3. Verify tool versions: cargo run --bin dependency-installer list

Permission Issues

If you get permission errors:

chmod +x ./scripts/pre-commit.sh

Best Practices

  1. Run early, run often: Don't wait until you have many changes to run pre-commit
  2. Fix issues incrementally: Address linter warnings as you code
  3. Use fast mode during development: Run full checks before final commit
  4. Read error messages carefully: They usually contain the solution
  5. Don't skip checks: They catch issues early and save CI time
  6. Keep commits small: Easier to debug if pre-commit fails

Related Documentation

Script Location

The pre-commit script is located at:

scripts/pre-commit.sh

You can also view the script source to understand what checks are being run:

cat scripts/pre-commit.sh

Integration with Git Hooks

While the project doesn't use automatic git hooks by default, you can optionally install a git pre-commit hook to run the script automatically:

./scripts/install-git-hooks.sh

This will create a .git/hooks/pre-commit file that runs the verification script before every commit.

Summary

Remember: The pre-commit script is your quality gate. It ensures:

  • Code quality standards are met
  • Tests pass consistently
  • Documentation is valid
  • No unused dependencies exist
  • Changes are ready for review

Running it before every commit saves time, prevents CI failures, and maintains project quality.
