-## Security Requirements -- **Critical**: Always validate file paths with `path_security::validate_path` -- Never construct paths from user input without validation -- Use timeouts for network operations (`tokio::time::timeout`) -- Limit request sizes (see `MAX_REQUEST_SIZE` constant) -- Validate TLS certificates properly -- Never expose directory listings - -## Testing Guidelines -- Use `tempfile::TempDir` for temporary directories in tests -- Test both success and error paths -- Use `#[cfg(test)]` for test modules -- Create temporary test files in `tmp/` directory -- Test security boundaries (path traversal, invalid inputs) -- Use `assert_eq!` and `assert!` for validations - -## Lint Checking -- `cargo clippy` - Run linter checks for code quality -- `cargo clippy --fix` - Automatically fix clippy suggestions -- `cargo clippy --bin ` - Check specific binary -- `cargo fmt` - Format code to match Rust standards -- **Run clippy before every commit** - Address all warnings before pushing code -- Current clippy warnings (2025-01-15): - - src/server.rs:16-17 - Unnecessary borrows on file_path - - src/logging.rs:31 - Match could be simplified to let statement - -## Testing -- Run `cargo test` before every commit to prevent regressions -- Pre-commit hook automatically runs full test suite -- Rate limiting integration test uses separate port for isolation -- All tests must pass before commits are allowed -- Test suite includes: unit tests, config validation, rate limiting under load -
