[Python-Dev] embedding - PyImport_AppendInittab() after Py_Initialize() (original) (raw)

Could anyone please clarify whether it is correct in python3.5 to call PyImport_AppendInittab() after Py_Initialize()

I found this case among the tests for boost.python https://github.com/boostorg/python/blob/develop/test/exec.cpp

And this test doesn't work for me with python3.5.An error looks like:

exec.cpp(137): Python Error detected in function 'void __cdecl check_pyerr(bool)' Traceback (most recent call last): File "", line 1, in ImportError: 'embedded_hello' is not a built-in module 1 error detected.

After debugging I found out that root cause is in importlib/_bootstrap.py which do the following:

    if fullname not in sys.builtin_module_names:
        raise ImportError('{!r} is not a built-in

module'.format(fullname), name=fullname)

but sys.builtin_module_names is the constant which initialized once in Py_Initialize()

To summarize: Is it a bug in python3.5 or original test inside boost.python should be fixed ? -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://mail.python.org/pipermail/python-dev/attachments/20160527/552c4b8b/attachment.html>
