Comprehensive review covering: - Project architecture and workspace organization - Code quality analysis with specific issues identified - Error handling patterns and recommendations - Test coverage gaps (critical: missing CLI tests) - Security analysis - Performance optimizations - API design evaluation - Dependency analysis Key findings: - Critical: Library code panics on invalid patterns (should return Result) - Critical: Hash calculation is broken (acknowledged in TODO) - High: Multiple unwrap() calls that could panic - Missing: Integration tests for CLI commands - Performance: O(n*m) complexity in owner/tag collection
This commit addresses the critical and high-priority issues identified in the comprehensive code review. ## Critical Fixes ### 1. Remove panics from library code (types.rs) - Changed `codeowners_entry_to_matcher()` to return `Result<CodeownersEntryMatcher, PatternError>` - Added new `PatternError` type with proper error message formatting - Updated all callers to handle the Result properly ### 2. Fix unwrap() calls in cache.rs - Replaced `unwrap()` with proper error handling using `match` and `filter_map` - Added graceful fallback for files that fail ownership resolution - Changed stdout flush to use `let _ =` to ignore errors ### 3. Fix broken hash calculation (common.rs) - Added exclusion patterns for `.codeowners.cache` files - Implemented double-check in diff callback to skip cache files - Fixed the `and_then` closure returning wrong type ### 4. Add CLI integration tests - Added 22 comprehensive integration tests covering: - Basic commands (help, version, config) - All codeowners subcommands (parse, list-files, list-owners, etc.) - Shell completion generation (bash, zsh, fish) - Various CLI flags and options - Error handling for invalid inputs ## High Priority Fixes ### 5. Improve error Display to include source context - Modified `Display` impl to include source error message in output ### 6. Remove empty start() function (core/mod.rs) - Removed unused `start()` function that did nothing ### 7. Add recursion depth limit to find_codeowners_files - Added MAX_RECURSION_DEPTH constant (100) - Implemented depth tracking to prevent stack overflow on deep directory structures ## Files Changed - types.rs: Return Result from codeowners_entry_to_matcher, add PatternError - cache.rs: Graceful error handling, filter invalid patterns with warnings - infer_owners.rs: Handle Result from matcher conversion - common.rs: Fix hash calculation, add recursion limit - error.rs: Include source in Display - mod.rs: Remove empty function - resolver_bench.rs: Handle Result in benchmarks - test_cli.rs: Add 22 integration tests
## Performance Improvements ### Optimize owner/tag collection (cache.rs) - Changed from O(owners × files) to O(files) complexity - Build owners_map and tags_map in single pass through file_entries - Removed unused collect_owners and collect_tags functions from common.rs ### Fix lifetime warnings (smart_iter.rs) - Added explicit lifetime `'_` to trait and impl return types - Fixes compiler warnings about elided lifetimes ## Bug Fixes ### Fix path normalization in inspect command - Handle ./ prefix variations when looking up files in cache - Normalize both cached paths and input paths for comparison - Updated test to properly assert success with ownership verification ## Code Cleanup - Removed unused functions: collect_owners, collect_tags - Removed unused imports: Owner, Tag from common.rs
## New Features ### Add --quiet / -q global flag - Suppress progress output during cache building - Added to AppConfig for consistent access - Updated cache.rs to check quiet mode before printing progress - Added test for quiet flag functionality ## CLI Improvements ### Clean up deprecated TODO comments - Removed obsolete AppSettings TODO comments (superseded by clap 4) - Updated command attributes to use modern clap 4 syntax - Added subcommand_required and arg_required_else_help ### Documentation improvements - Better help text for CLI options - Consistent formatting of option descriptions ## Files Changed - ci/src/cli/mod.rs: Add --quiet flag, clean up TODOs, modernize clap config - codeinput/src/utils/app_config.rs: Add quiet field to AppConfig - codeinput/src/utils/logger.rs: Add quiet field to fallback configs - codeinput/src/core/cache.rs: Check quiet mode before printing progress - ci/tests/test_cli.rs: Add test for --quiet flag
- Remove unused `CodeownersEntry` import from common.rs - Add #[allow(deprecated)] to suppress cargo_bin deprecation in tests
Mark all completed fixes with ✅ checkmarks and update conclusion section to reflect the current state of the codebase.
Add detailed doc comments with examples for: - CodeownersEntry: Parsed ownership rule structure - InlineCodeownersEntry: File-embedded ownership declarations - Owner: Owner representation with type classification - OwnerType: Classification enum for owner types - Tag: Metadata tag for categorization - OutputFormat: CLI output format enum - FileEntry: File with resolved ownership - CodeownersCache: Pre-computed cache structure
Mark documentation and module visibility as completed/verified.
- Add CACHE_VERSION constant (v1) to track cache format - Update CodeownersCache to include version field - Update Serialize/Deserialize to handle version - Check version on load and rebuild if outdated - Handle deserialization failures gracefully by rebuilding - Remove redundant cache verification load in parse command This ensures that cache format changes trigger automatic rebuilds instead of cryptic deserialization errors.
- Use strip_prefix instead of manual string slicing - Use clamp() instead of .min().max() pattern - Add #[allow(clippy::too_many_arguments)] for complex functions
