**REFERENCES edge type** (PR #217): New edge kind for symbol references that aren't direct calls (map/dispatch lookups, string-keyed handlers), including Python and TypeScript patterns. - **`recurse_submodules` build option** (PR #215): Build/update can now optionally recurse into git submodules. - **`.gitignore` default for `.code-review-graph/`** (PR #185): Fresh installs automatically add the SQLite DB directory to `.gitignore` so the database isn't accidentally committed. - **Clearer gitignore docs** (PR #171, closes #157): Documentation now spells out that `code-review-graph` already respects `.gitignore` via `git ls-files`. +- **Parser refactoring**: Extracted 16 per-language handler modules into `code_review_graph/lang/` package using a strategy pattern, replacing monolithic conditionals in `parser.py` +- **Jedi-based call resolution**: New `jedi_resolver.py` module resolves Python method calls at build time via Jedi static analysis, with pre-scan filtering by project function names (36s to 3s on large repos) +- **PreToolUse search enrichment**: New `enrich.py` module and `code-review-graph enrich` CLI command inject graph context (callers, callees, flows, community, tests) into agent search results passively +- **Typed variable call enrichment**: Track constructor-based type inference and instance method calls for Python, JS/TS, and Kotlin/Java +- **Star import resolution**: Resolve `from module import *` by scanning target module's exported names +- **Namespace imports**: Track `import * as X from 'module'` and CommonJS `require()` patterns +- **Angular template parsing**: Extract call targets from Angular component templates +- **JSX handler tracking**: Detect function/class references passed as JSX event handler props +- **Framework decorator recognition**: Identify entry points decorated with `@app.route`, `@router.get`, `@cli.command`, etc., reducing dead code false positives +- **Module-level import tracking**: Track module-qualified call resolution (`module.function()`) +- **Thread safety**: Double-check locking on parser caches (`_type_sets`, `_get_parser`, `_resolve_module_to_file`, `_get_exported_names`) +- **Batch file storage**: `store_file_batch()` groups file insertions into 50-file transactions for faster builds +- **Bulk node loading**: `get_all_nodes()` replaces per-file SQL queries for community detection +- **Adjacency-indexed cohesion**: Community cohesion computed in O(community-edges) instead of O(all-edges), yielding 21x speedup (48.6s to 2.3s on 41k-node repos) +- **Phase timing instrumentation**: `time.perf_counter()` timing at INFO level for all build phases +- **Batch risk_index**: 2 GROUP BY queries replace per-node COUNT loops in risk scoring +- **Weighted flow risk scoring**: Risk scores weighted by flow criticality instead of flat edge counts +- **Transitive TESTED_BY lookup**: `tests_for` and risk scoring follow transitive test relationships +- **DB schema v8**: Composite edge index for upsert performance (v7 reserved by upstream PR #127) +- **`--quiet` and `--json` CLI flags**: Machine-readable output for `build`, `update`, `status` +- **829+ tests** across 26 test files (up from 615), including `test_pain_points.py` (1,587 lines TDD suite), `test_hardened.py` (467 lines), `test_enrich.py` (237 lines) +- **14 new test fixtures**: Kotlin, Java, TypeScript, JSX, Python resolution scenarios ### Changed -- Community detection is now bounded — large repos complete in reasonable time instead of hanging indefinitely. +- Community detection is now bounded -- large repos complete in reasonable time instead of hanging indefinitely. +- New `[enrichment]` optional dependency group for Jedi-based Python call resolution +- Leiden community detection scales resolution parameter with graph size +- Adaptive directory-based fallback for community detection when Leiden produces poor clusters +- Search query deduplication and test function deprioritization + +### Fixed +- **Dead code false positives**: Decorators, CDK construct methods, abstract overrides, and overriding methods with called parents no longer flagged as dead +- **E2e test exclusion**: Playwright/Cypress e2e test directories excluded from dead code detection +- **Unique-name plausible caller optimization**: Faster dead code analysis via pre-filtered candidate sets +- **Store cache liveness check**: Cached SQLite connections verified as alive before reuse + +### Performance +- **Community detection**: 48.6s to 2.3s (21x) on Gadgetbridge (41k nodes, 280k edges) +- **Jedi enrichment**: 36s to 3s (12x) via pre-scan filtering by project function names ## [2.2.2] -
