Summary

  • reject empty relevance-feedback requests in both sync and async local clients
  • add a congruence test covering empty positive and negative feedback

Closes #1446.

Validation

  • python -m compileall qdrant_client/qdrant_client.py qdrant_client/async_qdrant_client.py tests/congruence_tests/test_query.py
  • targeted test collected successfully: tests/congruence_tests/test_query.py::test_query_empty_feedback (1 selected)
  • local rejection check ran twice with identical output: ValueError: relevance feedback must not be empty

The server-backed congruence test was not executed because no Qdrant server was available at localhost:6333.

Walkthrough

Local synchronous and asynchronous query validation now rejects RelevanceFeedbackQuery objects with empty feedback. A congruence test verifies the local ValueError and the existing HTTP and gRPC errors for the same invalid query.

The async behavior is implemented, but focused coverage is missing and should be added to prevent future local-mode divergence.

Add async-local coverage for empty relevance feedback. The async local test exercises AsyncQdrantLocal.query_points, but only with vector and RecommendQuery inputs. It does not reach the RelevanceFeedbackQuery branch in _validate_query. Add an async case that awaits query_points with feedback=[] and asserts ValueError. Without this test, the async validator can regress and accept input that the synchronous local client rejects.
