knowsuchagency opened a new pull request #5543: Fix permission error when creating logs URL: https://github.com/apache/airflow/pull/5543 Just a heads up, I wasn't able to find a ticket in the airflow JIRA and I'm not sure the best method to try and test this change, so I don't expect this PR to be accepted. It's here for visibility in case someone would like to help shepherd me through the process of making this PR "good". ## Description prevents the scheduler raising `PermissionError: [Errno 13]` when creating log files where the relative path contains references to directories higher on the filesystem, preventing execution. traceback: ``` Process DagFileProcessor8-Process: Traceback (most recent call last): File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/multiprocessing/process.py", line 297, in _bootstrap self.run() File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/multiprocessing/process.py", line 99, in run self._target(*self._args, **self._kwargs) File "/Users/sfitzpatrick/virtualenvs/flow/lib/python3.7/site-packages/airflow/jobs.py", line 381, in helper set_context(log, file_path) File "/Users/sfitzpatrick/virtualenvs/flow/lib/python3.7/site-packages/airflow/utils/log/logging_mixin.py", line 170, in set_context handler.set_context(value) File "/Users/sfitzpatrick/virtualenvs/flow/lib/python3.7/site-packages/airflow/utils/log/file_processor_handler.py", line 65, in set_context local_loc = self._init_file(filename) File "/Users/sfitzpatrick/virtualenvs/flow/lib/python3.7/site-packages/airflow/utils/log/file_processor_handler.py", line 141, in _init_file os.makedirs(directory) File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/os.py", line 211, in makedirs makedirs(head, exist_ok=exist_ok) File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/os.py", line 211, in makedirs makedirs(head, exist_ok=exist_ok) File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/os.py", line 211, in makedirs makedirs(head, exist_ok=exist_ok) [Previous line repeated 3 more times] File "/usr/local/Cellar/python/3.7.3/Frameworks/Python.framework/Versions/3.7/lib/python3.7/os.py", line 221, in makedirs mkdir(name, mode) PermissionError: [Errno 13] Permission denied: '/Users/sfitzpatrick/airflow/logs/scheduler/2019-07-07/../../../../../../virtualenvs' ``` Make sure you have checked _all_ steps below. ### Jira - [ ] My PR addresses the following [Airflow Jira](https://issues.apache.org/jira/browse/AIRFLOW/) issues and references them in the PR title.
