This is acceptable for the initial implementation but should be enhanced with encryption in the future. + +2. **Connection Security**: SSL/TLS is enforced by default using IMAP4_SSL. + +3. **Input Validation**: All user inputs are validated on both client and server sides. + +4. **Error Handling**: Detailed error messages are provided to users, but sensitive information is not exposed. + +## Performance Considerations + +1. **Connection Pooling**: Each operation creates a new connection to avoid state issues. + +2. **Timeout Handling**: Connection timeouts are configurable to prevent hanging. + +3. **Error Recovery**: Failed connections are properly cleaned up to avoid resource leaks. + +## Error Handling Strategy + +1. **Connection Errors**: Clear error messages for authentication failures, network issues, and server problems. + +2. **Validation Errors**: Field-specific validation errors for form inputs. + +3. **Sync Errors**: Detailed error messages for folder synchronization failures. + +4. **Logging**: All errors are logged to the console for debugging. + +## Success Metrics + +1. **Functional**: Users can configure IMAP connections, test them, and sync folders successfully. + +2. **Usability**: The UI is intuitive and provides clear feedback for all operations. + +3. **Reliability**: IMAP connections are stable and handle various server configurations. + +4. **Performance**: Folder synchronization completes in reasonable time. + +5. **Security**: User credentials are handled securely. + +## Acceptance Criteria + +Based on the original requirements: + +1. ✅ **Verify that a user can enter their imap server's connection details, and that they can be saved** + - Users can access the IMAP configuration modal + - Form validation ensures all required fields are filled + - Configuration is saved to the user's `imap_config` field + +2. ✅ **Verify that, once the connection is made, the list of folders are created for that user, copying the name and structure from IMAP** + - Connection testing validates the IMAP server access + - Folder synchronization fetches all available folders + - Folders are created in the local database with appropriate names + +3. ✅ **Verify that nested folders are just created with slashes in the name** + - Nested folder names from IMAP servers are preserved with slash notation + - Display names maintain the hierarchical structure + +4. ✅ **Verify that a failed connection attempt gives the user a validation error message and allows them to retry** + - Connection failures show clear error messages + - Users can modify their configuration and retry the connection + - Form validation prevents submission with invalid data + +## Implementation Plan + +### Phase 1: Core IMAP Service +1. Create `app/imap_service.py` with basic IMAP connection functionality +2. Implement connection testing logic +3. Add folder listing and synchronization + +### Phase 2: UI Integration +1. Create IMAP configuration modal template +2. Add routes for IMAP configuration and testing +3. Update sidebar to include IMAP settings option + +### Phase 3: Testing and Validation +1. Write unit tests for IMAP service +2. Write integration tests for IMAP routes +3. Test with various IMAP server configurations + +### Phase 4: Error Handling and Polish +1. Add comprehensive error handling +2. Improve user feedback and validation messages +3. Optimize performance and reliability + +This design provides a comprehensive approach to implementing IMAP connectivity while maintaining the existing application architecture and following the established patterns. \ No newline at end of file diff --git a/requirements.txt b/requirements.txt index 612e7e7..a31b980 100644 --- a/requirements.txt +++ b/requirements.txt @@ -6,3 +6,4 @@ psycopg2-binary==2.9.7 pytest==7.4.0 beautifulsoup4==4.13.4 Flask-Migrate==4.1.0 +imapclient==3.0.1 diff --git a/tests/test_imap_routes.py b/tests/test_imap_routes.py new file mode 100644 index 0000000..ea4fc3e --- /dev/null +++ b/tests/test_imap_routes.py @@ -0,0 +1,63 @@ +import pytest +from app import create_app +from app.models import User, db, Folder + +class TestIMAPRoutes: + def test_imap_config_modal(self, client): + #
