Arvind Kandpal updated CASSANDRA-21482:
---------------------------------------
Summary: cqlshlib Cython compilation errors on Python 3.12 and 3.13 (was:
Fix cqlshlib Cython compilation errors on Python 3.12 and 3.13)
> cqlshlib Cython compilation errors on Python 3.12 and 3.13
> ----------------------------------------------------------
>
> Key: CASSANDRA-21482
> URL: https://issues.apache.org/jira/browse/CASSANDRA-21482
> Project: Apache Cassandra
> Issue Type: Bug
> Components: Tool/cqlsh
> Reporter: Arvind Kandpal
> Priority: Normal
>
> *Problem Description*
> When running cqlsh tests (cqlsh-test) on Python 3.12 and 3.13 with Cython
> enabled, the build fails during the compilation phase.
> *Root Cause Analysis*
> The build matrix currently enforces Cython < 3.0 (specifically version
> `0.29.37`). Python 3.12 introduced massive internal C-API refactoring, which
> completely removed fields like _PyCFrame.use_tracing.
> When the older Cython version attempts to compile cqlshlib/copyutil.py with
> line-tracing/profiling enabled for test coverage hooks, the generated C code
> tries to access this non-existent member, causing gcc to fail hard with:
> cqlshlib/copyutil.c: error: ‘_PyCFrame’ has no member named ‘use_tracing’`
> (Note: As a temporary bypass to unblock pipeline testing, the Cython test
> matrix for Python 3.12/3.13 has been skipped in CASSANDRA-20997 via
> Jenkinsfile filtering)
