Fixes

  • 🐛 Fix support for StreamingResponses with dependencies with yield or UploadFiles, close after the response is done. PR #14099 by @tiangolo.

Before FastAPI 0.118.0, if you used a dependency with yield, it would run the exit code after the path operation function returned but right before sending the response.

This change also meant that if you returned a StreamingResponse, the exit code of the dependency with yield would have been already run.

For example, if you had a database session in a dependency with yield, the StreamingResponse would not be able to use that session while streaming data because the session would have already been closed in the exit code after yield.

This behavior was reverted in 0.118.0, to make the exit code after yield be executed after the response is sent.

You can read more about it in the docs for Advanced Dependencies - Dependencies with yield, HTTPException, except and Background Tasks. Including what you could do if you wanted to close a database session earlier, before returning the response to the client.
