* bpo-46542: test_lib2to3 uses support.infinite_recursion() Fix a Python crash in test_lib2to3 when using Python built in debug mode: limit the recursion limit. The test_all_project_files() test of test_lib2to3 now uses the test.support.infinite_recursion() context manager when processing the infinite_recursion.py file to prevent a crash when Python is built in debug mode. The two test_all_project_files() tests now use subTest() and log the refactored/parsed filename (if test_lib2to3 is run in verbose mode). * Update Lib/lib2to3/tests/data/infinite_recursion.py Co-authored-by: Jelle Zijlstra <jelle.zijlstra@gmail.com> Co-authored-by: Łukasz Langa <lukasz@langa.pl> Co-authored-by: Jelle Zijlstra <jelle.zijlstra@gmail.com>
