[pypy-issue] [issue1723] test runner filling temp directory with _testcapi modules

mattip <matti.picus@gmail.com> added the comment: What do you think of the hash idea to build once, use many times? fwiw, we support various non-documented environmental variables to control things like where to put files (PYPY_USESSION_DIR), compiler (CC) and probably others, "someone" should document them in pypy/doc/config/index.rst ________________________________________ PyPy bug tracker <tracker@bugs.pypy.org> <https://bugs.pypy.org/issue1723> ________________________________________
