PR #1638, for bpo-28411, causes problems in some (very) edge cases. Until that gets sorted out, we're reverting the merge. PR #3506, a fix on top of #1638, is also getting reverted.
Return the dictionary used for the module administration (a.k.a.
``sys.modules``). Note that this is a per-interpreter variable.
-.. c:function:: PyObject* PyImport_GetModule(PyObject *name)
-
- Return the already imported module with the given name. If the
- module has not been imported yet then returns NULL but does not set
- an error. Returns NULL and sets an error if the lookup failed.
-
- .. versionadded:: 3.7
.. c:function:: PyObject* PyImport_GetImporter(PyObject *path)
and module are affected by this change. (Contributed by INADA Naoki and
Eugene Toder in :issue:`29463`.)
-* ``PyInterpreterState`` no longer has a ``modules`` field. Instead use
- ``sys.modules``.
-
* The *mode* argument of :func:`os.makedirs` no longer affects the file
permission bits of newly-created intermediate-level directories.
To set their file permission bits you can set the umask before invoking
