josh-fell opened a new pull request #16874: URL: https://github.com/apache/airflow/pull/16874
Related to #10285 - Updated example DAG files such that `xcom_pull()` calls use an operator's `.output` property - Added comments to which task dependencies, if any, are handled and/or created via `XComArgs` for transparency - Removed or refactored the `default_args` pattern where necessary as requested by @ashb (i.e. removed a separated `default_args` declaration for deference for declaration as part of the `DAG` object) - Other miscellaneous updates based on `.output` refactoring >**Note:** There are several instances where the `xcom_pull()` call was not updated. These instances involve accessing a specific value within the `XCom` or calling user-defined macros with an `XCom` value. Reference #16618 for an open issue to enhance the `XComArg` functionality to provide similar behavior as the classic `xcom_pull()` method. > **Note:** Not all DAGs were tested functionally (i.e. with hard integrations to source systems and executed), however each DAG was tested to compile and generate a DAG graph as expected locally. An detailed summary of all changes made as part of this PR can be found below: | DAG File | Converted `xcom_pull()`? | Other Updates? | Comments | | ---------| ------------------------ | -------------- | -------- | | airflow/providers/jenkins/example_dags/example_jenkins_job_trigger.py | Yes | Yes | Removed explicit task dependencies that are created via `XComArgs`. </br></br>Refactored `grab_artifact_from_jenkins()` function to take an input `XComArgs` from a previous task. </br></br>Refactored `default_args` pattern. | --- **^ Add meaningful description above** Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/CONTRIBUTING.rst#pull-request-guidelines)** for more information.
