Line(s) |
Issue |
Consensus Severity |
| 1 |
Model/CategoryList.php |
83-86 |
N+1 Loading: categoryRepository->get() called per category ID in loop after collection->getData(). Should use batch getList() with SearchCriteria. |
Critical (Claude+Gemini: Critical, Codex: High) |
| 2 |
Model/ProductRepository.php |
728-738 |
N+1 Loading: readExtensions->execute() called per product after collection load. Extension attributes loaded one-by-one. |
High (Claude+Gemini: High, Codex: Medium) |
| 4 |
Model/Config.php |
205, 274 |
Full Collection Load: _setCollectionFactory->create()->load() and _groupCollectionFactory->create()->load() without addFieldToSelect. Loads all columns for attribute sets/groups. |
Medium |
| 7 |
Model/ProductRepository.php |
242 |
Memory Issue: Product cache with configurable limit (default 1000) but no eviction policy. Can grow unbounded in long-running processes. |
Medium |
Methodology
- Static code analysis with grep + file reads against 8 anti-pattern categories
- Cross-validated by 3 AI systems independently
- Runtime profiling with PHP-SPX recommended before implementing fixes
