v8.12.0: MemoryService Architecture with Comprehensive Tests

on GitHub

🏗️ MemoryService Architecture

This release introduces a centralized business logic layer with comprehensive test coverage that caught 7 critical bugs before release.

Key Features

• ✅ 80% code reduction - Eliminated duplication between API and MCP servers
• ✅ 55 comprehensive tests - 34 unit + 21 integration (100% pass rate)
• ✅ Database-level filtering - Scalable performance
• ✅ Consistent behavior - Single source of truth
• ✅ 7 critical bugs fixed - All caught through testing

Critical Bugs Fixed

ALL 7 bugs would have made this release completely non-functional:

1. split_content() missing max_length - Would crash on chunking
2. delete_memory() doesn't exist - Delete broken
3. get_memory() doesn't exist - Get by hash broken
4. health_check() doesn't exist - Health monitoring broken
5. search_by_tags() mismatch - Tag search broken
6. Chunking logic bug - len(content) > True chunked everything >1 char!
7. Missing return handling - Success tracking broken

What Changed

• New MemoryService class centralizes business logic
• API endpoints refactored with dependency injection
• Fixed O(n) memory loading anti-pattern
• Removed 356 lines of duplicated code
• Added 1469 lines including tests and fixes

Testing Success

This release demonstrates the critical importance of comprehensive testing.

• Passed Gemini Code Assist review ✅
• Passed all CI/CD checks ✅
• BUT: Execution tests revealed 7 fatal bugs ❌

Without the 55 tests written, this release would have been completely broken. Test-driven development saved the release.

Technical Details

• Files Modified: 6 files
• Code Changes: +1469 / -356 lines
