[New-bugs-announce] [issue13429] provide __file__ to extension init function

[Stefan Behnel]

New submission from Stefan Behnel <scoder at users.sourceforge.net>:

In Python modules, the top-level module code sees the __file__ variable and can use it to refer to resources in package subdirectories, for example. This is not currently possible in extension modules, because __file__ is only set after running the module init function, and the module has no way to find out its runtime location.

CPython should set __file__ directly in PyModule_Create2(), based on information provided by the shared library loader. This would let PyModule_GetFilenameObject() work immediately with the newly created module object.

The relevant python-dev thread is here:

A patch will follow soon.
