Summary

Addresses points 1 and 3 of #4505.

Separates the real OpenAI Responses API call from telemetry/instrumentation work so that:

  • real OpenAI/API exceptions propagate unchanged;
  • telemetry failures after a successful API call are logged and contained;
  • the original successful response is returned unchanged;
  • sync and async Responses API paths are covered;
  • sync and async cancellation paths are covered.

Point 2 of #4505 (removing the four no-op @dont_throw decorators) is already covered by #4506 and is intentionally not duplicated here.

Tests

  • Responses API telemetry failure regression tests (sync)
  • Async Responses API telemetry failure regression tests
  • Real OpenAI exception propagation tests (sync & async)
  • Cancellation telemetry failure tests (sync & async)
  • Exception logger crash resilience test
  • Existing Responses API test suite

Validation

  • Syntax verification:
    python -m py_compile packages/opentelemetry-instrumentation-openai/opentelemetry/instrumentation/openai/v1/responses_wrappers.py packages/opentelemetry-instrumentation-openai/tests/traces/test_responses.py -> Exit code: 0
  • Pytest regression execution:
    python -m pytest scratch/verify_regression.py -v -> 6 passed in 0.77s
  • Git diff verification:
    git diff --check -> Clean exit, no whitespace errors
    git diff -U1 ... | grep dont_throw -> 0 modifications, preserving fix(openai): remove no-op dont_throw from Responses API wrappers #4506 scope

Summary by CodeRabbit

  • Bug Fixes
    • OpenAI Responses API calls now preserve their original outcomes when telemetry processing fails: successful calls still return their responses, and request errors continue to propagate.
    • Cancellation calls also return their original responses if telemetry processing encounters an error.
    • Streaming responses are handled without attempting to read response fields, and telemetry errors are logged for troubleshooting.
    • These safeguards apply to both synchronous and asynchronous requests, including error handling when recording telemetry for failed requests.

📝 Walkthrough

Walkthrough

The synchronous and asynchronous Responses wrappers guard telemetry processing for create and cancel calls. They log telemetry failures and preserve the original API response or request exception. Raw-response streams are returned without tracing.

Changes

Responses API telemetry handling

Layer / File(s) Summary
Create call telemetry handling
packages/opentelemetry-instrumentation-openai/opentelemetry/instrumentation/openai/v1/responses_wrappers.py, packages/opentelemetry-instrumentation-openai/tests/traces/test_responses.py
The create wrappers guard error-span and response processing. They log telemetry failures, preserve successful responses and request exceptions, and return raw-response streams untraced. Tests cover synchronous and asynchronous calls, including failures in the configured exception logger.
Cancellation telemetry handling
packages/opentelemetry-instrumentation-openai/opentelemetry/instrumentation/openai/v1/responses_wrappers.py, packages/opentelemetry-instrumentation-openai/tests/traces/test_responses.py
The cancellation wrappers guard parsing and span emission. If telemetry processing fails, they return the original response. Tests cover synchronous and asynchronous cancellation calls.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Suggested reviewers: markuspalme

Merge Risk: ⚪ Minimal · up to 59cfe

The Responses wrappers preserve API responses and request errors when telemetry fails. The reviewed changes leave no actionable merge-blocking risk.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 59cfe

The change appears to improve isolation between telemetry failures and API results without adding an externally reachable entrypoint. No introduced security issue was established, although trace-state cleanup and deployment-specific logging remain relevant limits.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The changed behavior can affect callers using this instrumentation for Responses create and cancel, but the examined changes add no independently reachable endpoint or privilege.

Trust Boundaries and Controls

  • observed — When a request call fails, telemetry recording is attempted inside a separate guarded path and the original exception is re-raised. A successful cancellation calls the SDK before guarded telemetry work begins.

Resilience and Maintainability Implications

  • inferred — The pre-existing response-ID-only map does not make cancellation span emission atomic with state removal. Evidence does not establish provider ID uniqueness across callers, repeated-call behavior under concurrency, or recovery of lost telemetry state; it also does not show this PR introduced those conditions.

Hardening Proposals

  • proposed — Where deployments enable debug logs or configure an exception logger, assess whether telemetry exception text can contain sensitive request data before forwarding full tracebacks or exceptions.

1169-1214: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Assert that the error-telemetry failure path runs.

The second pytest.raises block patches set_data_attributes so that it fails. The test does not confirm that the patched function runs. set_data_attributes runs only when traced_data is not None. If TracedData construction fails, the test passes but does not test the telemetry-failure path. Assert that the mock was called. Also assert that Config.exception_logger received the RuntimeError. Make the same changes to the async counterpart at Lines 1252-1259.

Proposed change
-    monkeypatch.setattr(
-        rw, "set_data_attributes", MagicMock(side_effect=RuntimeError("error in error telemetry"))
-    )
+    failing = MagicMock(side_effect=RuntimeError("error in error telemetry"))
+    monkeypatch.setattr(rw, "set_data_attributes", failing)
     with pytest.raises(openai.RateLimitError):
         client.responses.create(
             model="gpt-4.1-nano",
             input="Hello",
         )
+    assert failing.called
