---------------------------------------
Assignee: Csaba Ringhofer
> PY_SSIZE_T_CLEAN error in some environments
> -------------------------------------------
>
> Key: THRIFT-5892
> URL: https://issues.apache.org/jira/browse/THRIFT-5892
> Project: Thrift
> Issue Type: Bug
> Components: Python - Library
> Affects Versions: 0.16.0, 0.22.0
> Reporter: Csaba Ringhofer
> Assignee: Csaba Ringhofer
> Priority: Major
>
> The error described in THRIFT-5488 comes up in some environments even after
> the original fix. I could reproduce this on a chainguard based docked image
> (GCC 15), while on my Ubuntu desktop things worked well (GCC 9) . I don't
> know the exact cause of the different behavior, on guess is the different GCC
> version
> Other info on the environment:
> Python: 3.11.13
> Thrift: 0.16 / 0.22 / master (probably all versions between but I didn't try)
> Adding #define PY_SSIZE_T_CLEAN to
> https://github.com/apache/thrift/blob/master/lib/py/src/ext/module.cpp before
> including Python.h solved the issue.
> The issue was discover in https://github.com/cloudera/impyla which tries to
> use the native binary protocol module:
> {code}
> >>> from impala.dbapi import connect
> >>> con=connect(host=...)
> >>> cur=con.cursor()
> Traceback (most recent call last):
> File "<stdin>", line 1, in <module>
