New submission from Jonas Witschel <g...@diabonas.de>:
Consider the following minimal example C code which is trying to import jsonschema (https://python-jsonschema.readthedocs.io/en/stable/), compiled using "gcc test_newinterpreter.c -I /usr/include/python3.10 -lpython3.10 -o test_newinterpreter" or similar: #include <Python.h> int main(void) { Py_Initialize(); PyThreadState *interpreter = Py_NewInterpreter(); PyRun_SimpleString("import jsonschema"); Py_Finalize(); } In Python 3.9.9, this works as expected. However in Python 3.10.0, the following error is produced: Traceback (most recent call last): File "<string>", line 1, in <module> File "/usr/lib/python3.10/site-packages/jsonschema/__init__.py", line 21, in <module> from jsonschema._types import TypeChecker File "/usr/lib/python3.10/site-packages/jsonschema/_types.py", line 168, in <module> draft3_type_checker = TypeChecker( TypeError: TypeChecker() takes no arguments Removing the Py_NewInterpreter() call makes the example work as expected in Python 3.10.0. This might be related to the enhancements to the type cache from bpo-42745. Another recent bug report I found that might possibly be related is bpo-46036. This bug breaks some WeeChat plugins that try to import one of the affected modules, e.g. weechat-matrix (https://github.com/poljar/weechat-matrix). ---------- components: C API, Subinterpreters messages: 408295 nosy: diabonas priority: normal severity: normal status: open title: When using Py_NewInterpreter, some modules fail to import in Python 3.10 type: compile error versions: Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46047> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
