Add SQL implementation of SandboxedConversationService

openhands-agent · openhands-agent · commit 875e1f7f5295 · 2025-09-28T22:32:45.000Z
- Created SQLSandboxedConversationService with full CRUD operations
- Implemented batch operations for efficient data retrieval
- Added HTTP client integration for agent status from OpenHands Agent Server
- Created SQLSandboxedConversationServiceResolver for dependency injection
- Updated dependency.py to use real SQL implementation instead of MagicMock
- Fixed imports to use correct AgentState from openhands.core.schema
- Modeled after existing sql_user_service.py patterns

+"""SQL implementation of SandboxedConversationService.
+
+This implementation provides CRUD operations for sandboxed conversations focused purely on SQL operations:
+- Direct database access without permission checks
+- Batch operations for efficient data retrieval
+- Integration with SandboxService for sandbox information
+- HTTP client integration for agent status retrieval
+- Full async/await support using SQL async sessions
+
+Security and permission checks are handled by wrapper services.
+
+Key components:
+- SQLSandboxedConversationService: Main service class implementing all operations
+- SQLSandboxedConversationServiceResolver: Dependency injection resolver for FastAPI
