I recently hit on a situation that created a one million line code file: https://github.com/pytest-dev/pytest/issues/4406#issuecomment-439629715 The original file (which is included in SymPy) has 3000 lines averaging 500 characters per line so that the total file is 1.5MB. Since it is a test file pytest rewrites the corresponding pyc file and adds extra lines to annotate the intermediate results in the large expressions. The pytest-rewritten code has just over a million lines. When I first tried pytest with this file it lead to a CPython segfault. It seems that the crash in CPython was fixed in 3.7.1 though so subsequent versions can work fine with this (although it is slow). The tests in the file are skipped anyway so I just made sure that the file was blacklisted in SymPy's pytest configuration. -- Oscar _______________________________________________ Python-Dev mailing list -- python-dev@python.org To unsubscribe send an email to python-dev-le...@python.org https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/python-dev@python.org/message/IUG6EBERWZJKWOF2LJTQJKCUXTJTQXS5/ Code of Conduct: http://python.org/psf/codeofconduct/
