--------------------------------------
Summary: [C++] Add errno detail to filesystem-raised errors
Key: ARROW-15896
URL: https://issues.apache.org/jira/browse/ARROW-15896
Project: Apache Arrow
Issue Type: Wish
Components: C++, Python
Reporter: Antoine Pitrou
Adding a conventional errno detail to filesystem-raised errors would allow the
Python side to raise the proper subexception, such as {{FileNotFoundError}} for
a non-existent path error (currently, a generic {{OSError}} is raised in
Python).
