From 7522aefd2ab9b43135a35ea867b82b8e1970326a Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 6 Nov 2025 22:47:23 +0000 Subject: [PATCH 01/18] refactor: Implement Python src-layout directory structure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major restructuring to align with Python best practices: ## Changes ### 1. New Package Structure - Created `src/codebase_rag/` as main package directory - All application code now under `src/` (PyPA standard) - Moved `__version__.py` to `src/codebase_rag/` ### 2. Configuration Module - Moved `config.py` → `src/codebase_rag/config/settings.py` - Split validation functions → `src/codebase_rag/config/validation.py` - Added backward compatibility shim with deprecation warning ### 3. Services Reorganization - Reorganized services into logical subpackages: - `services/knowledge/` - Neo4j knowledge services - `services/memory/` - Memory store and extraction - `services/code/` - Code analysis and ingestion - `services/sql/` - SQL parsing - `services/tasks/` - Task queue and processing - `services/utils/` - Utilities (git, ranker, metrics) - `services/pipeline/` - Data pipeline - `services/graph/` - Graph schema ### 4. MCP Package Restructuring - Renamed `mcp_tools/` → `src/codebase_rag/mcp/` - Moved `mcp_server.py` → `src/codebase_rag/mcp/server.py` - Organized handlers into `mcp/handlers/` subpackage - Renamed `tool_definitions.py` → `tools.py` ### 5. Entry Points Consolidation - Created `src/codebase_rag/server/` package: - `web.py` - Web server entry point - `mcp.py` - MCP server entry point - `cli.py` - CLI utilities - Updated `start.py` and `start_mcp.py` as thin wrappers - Enhanced `__main__.py` for `python -m codebase_rag` ### 6. Core and API Modules - Moved `core/` → `src/codebase_rag/core/` - Moved `api/` → `src/codebase_rag/api/` ### 7. Docker and CI/CD Updates - Updated all Dockerfiles to use new `src/` structure: - `Dockerfile` - `docker/Dockerfile.minimal` - `docker/Dockerfile.standard` - `docker/Dockerfile.full` - Updated GitHub workflows: - Fixed version path in `docker-build.yml` ## Benefits - Cleaner root directory - Clear package boundaries - Standard Python project structure - Better imports organization - Backward compatibility maintained ## Breaking Changes - Direct imports from old locations deprecated (warnings added) - Docker builds require updated COPY commands (already done) Refs:

start.py - start_mcp.py - main.py - config.py (backward compat shim) - mcp_server.py ### Old Code Directories (duplicates removed) - api/ → now only in src/codebase_rag/api/ - core/ → now only in src/codebase_rag/core/ - services/ → now only in src/codebase_rag/services/ - mcp_tools/ → now only in src/codebase_rag/mcp/ - config/ → moved to examples/configs/ ## Updated Files ### pyproject.toml - Added proper console_scripts entry points: - codebase-rag (main CLI) - codebase-rag-web (web server) - codebase-rag-mcp (MCP server) - Updated [tool.setuptools] to use src-layout package discovery - Updated [tool.coverage.run] source paths ### All Dockerfiles - Removed COPY of old entry scripts - Updated CMD to use: python -m codebase_rag - Simplified COPY to just: COPY src ./src ### Import Fixes (20 files updated) - All imports updated from old paths to new src.codebase_rag paths - Fixed in: api/, core/, services/, mcp/, server/ ## New Standard Usage ### Command Line ```bash # Direct module invocation python -m codebase_rag # Start both services python -m codebase_rag --web # Web only python -m codebase_rag --mcp # MCP only python -m codebase_rag --version # After pip install (console_scripts) codebase-rag # Main CLI codebase-rag-web # Web server codebase-rag-mcp # MCP server ``` ### Docker ```dockerfile CMD ["python", "-m", "codebase_rag"] ``` ## Benefits - ✅ 100% src-layout compliant - ✅ No backward compatibility complexity - ✅ Cleaner root directory (21 items → 18 items) - ✅ Standard Python package structure - ✅ Proper entry points via setuptools - ✅ No duplicate code ## Breaking Changes - Old entry scripts removed (use python -m codebase_rag) - Old import paths removed (use src.codebase_rag.*) - Root-level code directories removed Refs: #complete-src-layout-migration --- Dockerfile | 6 +- api/__init__.py | 1 -

Problem: When the package is installed or run via `python -m codebase_rag` or the installed CLI commands (codebase-rag, codebase-rag-web, codebase-rag-mcp), Python only knows about the `codebase_rag` package namespace, not `src.codebase_rag`. This caused ModuleNotFoundError and prevented the application from starting. Solution: Replaced all imports within src/codebase_rag/ from: - from src.codebase_rag.X import Y To: - from codebase_rag.X import Y This ensures the package works correctly when: 1. Installed via pip (pip install -e .) 2. Run as module (python -m codebase_rag) 3. Run via console scripts (codebase-rag, codebase-rag-web, codebase-rag-mcp) Changes: 35 files, 83 imports updated Files affected: - All __init__.py files in the package - All service modules - All API routes - All MCP handlers - Server entry points - Core application files --- src/codebase_rag/__init__.py | 2 +- src/codebase_rag/__main__.py | 6 ++--- src/codebase_rag/api/memory_routes.py | 4 ++-- src/codebase_rag/api/neo4j_routes.py | 2 +- src/codebase_rag/api/routes.py | 22 +++++++++---------- src/codebase_rag/api/sse_routes.py | 2 +- src/codebase_rag/api/task_routes.py | 6 ++--- src/codebase_rag/api/websocket_routes.py | 2 +- src/codebase_rag/config/__init__.py | 4 ++-- src/codebase_rag/config/validation.py | 2 +- src/codebase_rag/core/app.py | 2 +- src/codebase_rag/core/exception_handlers.py | 2 +- src/codebase_rag/core/lifespan.py | 8 +++---- src/codebase_rag/core/logging.py | 2 +- src/codebase_rag/core/middleware.py | 2 +- src/codebase_rag/core/routes.py | 12 +++++----- src/codebase_rag/mcp/__init__.py | 2 +- src/codebase_rag/mcp/handlers/__init__.py | 2 +- src/codebase_rag/mcp/server.py | 22 +++++++++---------- src/codebase_rag/server/cli.py | 2 +- src/codebase_rag/server/mcp.py | 2 +- src/codebase_rag/server/web.py | 8 +++---- src/codebase_rag/services/__init__.py | 6 ++--- src/codebase_rag/services/code/__init__.py | 6 ++--- .../services/code/graph_service.py | 2 +- .../services/knowledge/__init__.py | 2 +- .../knowledge/neo4j_knowledge_service.py | 2 +- src/codebase_rag/services/memory/__init__.py | 4 ++-- .../services/memory/memory_extractor.py | 2 +- .../services/memory/memory_store.py | 2 +- src/codebase_rag/services/sql/__init__.py | 6 ++--- src/codebase_rag/services/tasks/__init__.py | 6 ++--- .../services/tasks/task_storage.py | 2 +- src/codebase_rag/services/utils/__init__.py | 6 ++--- src/codebase_rag/services/utils/metrics.py | 2 +- 35 files changed, 83 insertions(+), 83 deletions(-) diff --git a/src/codebase_rag/__init__.py b/src/codebase_rag/__init__.py index 712b84f..115c339 100644 --- a/src/codebase_rag/__init__.py +++ b/src/codebase_rag/__init__.py @@ -5,7 +5,7 @@ Supports MCP protocol for AI assistant integration.
