21e21747ea ci: modernize tooling with prek, ty, and security scanning (#14956)
* ci: modernize tooling with prek, ty, and security scanning

Migrate from pre-commit to prek (Rust-native, faster hooks) and add
comprehensive CI improvements for code quality and security.

Changes:
- Replace pre-commit with prek for git hooks
- Add ty type checker (Rust-based, replaces mypy)
- Expand ruff rules: security (S), simplify (SIM), commented code (ERA)
- Add pip-audit workflow for Python dependency CVE scanning
- Add actionlint and zizmor for GitHub Actions linting/security
- Add ruff format check to CI
- Enable stricter ansible-lint rules (no-changed-when, risky-file-permissions)
- Remove obsolete Claude workflow files
- Apply ruff formatting fixes to test files

* fix(ci): resolve actionlint install and ty type errors

- Use actionlint's official install script instead of broken URL pattern
- Exclude test mock modules from ty type checking
- Run workflows on push only for main/master to avoid duplicate PR runs

* fix(ci): use glob pattern for actionlint, exclude all tests from ty

- actionlint requires *.yml glob, not directory path
- Exclude all tests from ty type checking (test code has looser typing)

* fix(ci): quote shell variables to fix shellcheck warnings

Fix SC2046/SC2086 warnings in workflow scripts:
- Quote $(uname -r) in apt-get install
- Quote $(pwd) in docker volume mount
- Quote $existing in gh issue comment

* fix(ci): move key-order[task] to warn_list

Too many existing violations in the codebase to enable as error.
Move to warn_list for gradual fixes over time.

Tests

Running Tests

# Run all linters (same as CI)
ansible-lint . && yamllint . && ruff check . && shellcheck scripts/*.sh

# Run Python unit tests
pytest tests/unit/ -q

# Run E2E connectivity tests (requires deployed Algo on localhost)
sudo tests/e2e/test-vpn-connectivity.sh both

Test Coverage

Category Tests What's Verified
Sanity test_basic_sanity.py Python version, config syntax, playbook validity
Config test_config_validation.py WireGuard/IPsec config formats, key validation
Templates test_template_rendering.py Jinja2 template syntax, filter compatibility
Certificates test_certificate_validation.py OpenSSL compatibility, PKCS#12 export
Cloud Providers test_cloud_provider_configs.py Region formats, instance types, OS images
E2E test-vpn-connectivity.sh WireGuard handshake, IPsec connection, DNS through VPN

CI Workflows

Workflow Trigger What It Does
lint.yml All PRs ansible-lint, yamllint, ruff, shellcheck
main.yml Push to master Syntax check, unit tests, Docker build
integration-tests.yml PRs to roles/ Full localhost deployment + E2E tests
smart-tests.yml All PRs Runs subset based on changed files

Writing Tests

Python Unit Tests

Place in tests/unit/. Use fixtures from conftest.py:

def test_something(mock_ansible_module, jinja_env):
    # mock_ansible_module - mocked AnsibleModule
    # jinja_env - Jinja2 environment with Ansible filters
    pass

Shell Scripts

Use bash strict mode and pass shellcheck:

#!/bin/bash
set -euo pipefail

Troubleshooting

E2E tests fail with "namespace already exists"

sudo ip netns del algo-client

Template tests fail with "filter not found" Add the filter to the mock in conftest.py.

CI fails but local passes Check Python/Ansible versions match CI (Python 3.11, Ansible 12+).
