The generic response.*.delta branch could leave the streaming handler in two states that crash the caller. It bound its result only inside the guard that checks the target item exists, but returned that result outside the guard, so a delta arriving before its output item, or carrying an index past the end, raised UnboundLocalError. Separately, an event name with only two dot-separated parts failed the length check and fell off the end of the branch, so the function returned None and both call sites raised TypeError unpacking it. Where the response is streamed to a browser both crashes were swallowed at debug level and cost a chunk. On the direct API path there is no handler between here and the server, so the caller kept its 200 while the body was cut short with no [DONE], and the outlet filters never ran. The return now sits inside the guard with a branch-level fallback that hands back the accumulated output untouched, which is what the sibling done branch and every other skip path in this function already do. Deltas whose item exists behave exactly as before. Dropping an orphan delta is deliberate rather than synthesizing the missing item: response.output_item.added appends without regard to output_index, so a placeholder would be duplicated when the real item arrives, and a fabricated function_call would have no name or call id. |
