slice-soupam opened a new pull request, #72297: URL: https://github.com/apache/airflow/pull/72297
Adds handling for `SetXCom` requests sent from a Dag file processor subprocess to the manager. Dag callbacks and top-level code invoked during parsing can call `XCom.set()`; without a handler for `SetXCom` in `DagFileProcessorProcess._handle_request`, those requests were previously left unhandled and would hang until the request timed out (`SetXCom` was still listed as unhandled in `in_task_runner_but_not_in_dag_processing_process`). Split out of #72008 per review feedback — the threading approach in that PR needs separate, focused review, and this change is unrelated and self-contained. --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Claude Code (Sonnet 5) Generated-by: Claude Code (Sonnet 5) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
