Katie Atkinson updated THRIFT-5715:
-----------------------------------
Summary: Python 3.11 Immutable errors can't be used with
contextlib.contextmanager (was: Immutable errors can't be used with
contextlib.contextmanager in Python 3.11)
> Python 3.11 Immutable errors can't be used with contextlib.contextmanager
> -------------------------------------------------------------------------
>
> Key: THRIFT-5715
> URL: https://issues.apache.org/jira/browse/THRIFT-5715
> Project: Thrift
> Issue Type: Bug
> Components: Python - Compiler
> Affects Versions: 0.14.1, 0.16.0, 0.18.1
> Environment: The client runtime is the python:3.10 and python:3.11
> docker images from dockerhub, installing the latest thrift library from pypi.
>
> The thrift compiler is installed on debian (v0.14.1 and v0.18.1) or ubuntu
> (v0.16.0).
> Reporter: Katie Atkinson
> Priority: Major
>
> Generated Thrift IDLs create exceptions that are immutable. In Python 3.11
> contextlib manipulates exceptions to update tracebacks. When a Thrift client
> raises an error within a context manager the context manager fails. This
> doesn't happen with Python 3.10.
> This example uses
> [tutorial.thrift|https://github.com/apache/thrift/blob/master/tutorial/tutorial.thrift].
> I compiled the IDL with versions v0.14.1, v0.16. and v0.18.1, each with the
> same result.
