bwangelme opened a new pull request, #2960: URL: https://github.com/apache/thrift/pull/2960
<!-- Explain the changes in the pull request below: --> ## What error occurred? When the Python client times out while reading content from the server, the exception thrown is not "read timeout," but rather "unexpected exception." ## Why this error happens ### the socket.timeout error doesn't includes the errno parameter in its args attribute. I try to make a timeout error on my pc, it only contains the error string. ``` Python 3.11.1 (main, Jan 5 2023, 14:25:08) [GCC 11.3.0] Type 'copyright', 'credits' or 'license' for more information IPython 8.13.2 -- An enhanced Interactive Python.

(not required, but preferred) - [X] Did you do your best to avoid breaking changes? If one was needed, did you label the Jira ticket with "Breaking-Change"? - [X] If your change does not involve any code, include `[skip ci]` anywhere in the commit message to free up build resources. <!-- The Contributing Guide at: https://github.com/apache/thrift/blob/master/CONTRIBUTING.md has more details and tips for committing properly. --> -- This is an automated message from the Apache Git Service.
