fix(groq): record token and duration metrics for streaming calls#4420chiruu12 wants to merge 2 commits into
Conversation
Streaming responses returned early into the stream processor without any metric instruments, so token usage, duration and choice metrics were only ever recorded for non-streaming calls. Thread the instruments through both stream processors and record on completion. Token recording is extracted into a shared helper so the two paths report the same metric under the same attributes. Moves tests/traces/conftest.py to tests/conftest.py so tests/metrics/ can share the fixtures, matching the openai package layout.

vcrpy 8 before_record_response vcr_config pytest-recording response headers callback documentation💡 Result:
In vcrpy (including version 8.0.0), the before_record_response configuration option allows you to intercept and modify HTTP responses before they are serialized into a cassette [1][2]. When using pytest-recording, you can apply this callback using the vcr_config fixture or the
@pytest.mark.vcrdecorator [3][4]. Key Information: 1. Functionality: The callback receives the response object and can either return a modified version of it (to scrub sensitive data like headers or body content) or return None to prevent the entire request/response pair from being recorded [1][2]. 2. Usage with pytest-recording: You can configure this globally via a vcr_config fixture [4]:@pytest.fixturedef vcr_config: return { "before_record_response": lambda response: response # Your logic here } Alternatively, you can apply it to specific tests:@pytest.mark.vcr(before_record_response=your_callback_function) def test_example: pass 3. Response Header Modification: To modify response headers specifically, your callback function can access and update the response['headers'] dictionary (which is represented as a dictionary of lists) before returning it [1][2]. 4. Implementation Note: VCRpy performs a deepcopy of the response object before passing it to the before_record_response callback to ensure that the original response object returned to your application code remains unmodified [5][6]. 5. Known Behavior: Some users have reported discrepancies between recording and playback behavior if the callback logic depends on the internal structure of the response being exactly identical during both phases [7]. Always ensure your scrubbing logic is idempotent and handles the response format consistently [1][2].Citations:

@dvirski could you approve the workflow runs on this one? GitGuardian has run and nothing else has, so the required checks have not started and there is no test signal to review against. Streaming Groq calls never recorded token or duration metrics because the metric emission sat on the non-streaming path only. This moves it so both paths report. |
Fixes #4419
Streaming calls returned into the stream processor before the metric block, and neither
_create_stream_processornor_create_async_stream_processortook a metric instrument. Sogen_ai.client.token.usageandgen_ai.client.operation.durationwere recorded for non-streaming calls only, with no warning, since the span attributes were still set correctly.Both processors now take
token_histogram,duration_histogramandstart_time, and record on completion. The usage was already being accumulated offchunk.x_groq.usage, it just never reached the histogram. The response model is captured from the chunks, since a streaming response has no single object to read it from.Two small refactors to avoid duplicating the recording logic:
record_token_usage_metrics()inspan_utils.py, now used by both paths so they emit the same metric under the same attributes.streaming_metrics_attributes(model)inutils.py.shared_metrics_attributes(response)now calls it, so behaviour there is unchanged.Tests
New
tests/metrics/, laid out like the openai package, running against recorded cassettes.This required moving
tests/traces/conftest.pytotests/conftest.pysotests/metrics/inherits the fixtures. The file contents are unchanged, and openai already uses that layout.On main, without the source change:
With the change, both pass.
Full package suite:
flake8 clean.
