New submission from STINNER Victor: When Python is built from source, the "Modules/" subdirectory is added to sys.path on UNIX. I don't understand why: it does not contain .py files nor .so dynamic modules. Dynamic modules are built in "build/lib.linux-x86_64-3.5-pydebug".
A side effect of adding Modules/ subdirectory to sys.path is that Modules subdirectories (ex: _sqlite, _ctypes, _io, _decimal, etc.) can be used as packages. For example, when the _decimal module cannot be compiled, Lib/decimal.py uses Modules/_decimal as a Python package which is wrong. The decimal becomes an empty module (no symbol, because Modules/_decimal does not contain an __init__.py nor any .so file) because decimal.py uses "import _decimal" at the end (see decimal.py). Attached patch removes Modules/ from sys.path on UNIX. Maybe adding Modules/ to sys.path was useful before the introduction of pybuildir.txt? See issue #9589 and the changeset 4742e7aea2f5 (and the issue #586680). ---------- files: getpath_no_modules.patch keywords: patch messages: 225955 nosy: haypo, pitrou priority: normal severity: normal status: open title: The Modules/ directory should not be added to sys.path Added file: http://bugs.python.org/file36484/getpath_no_modules.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22285> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
