New submission from Hartmut Goebel <h.goe...@crazy-compilers.com>: I have a test site containing nested namespace packages in zipped and unzipped eggs_
- nspkg3_aaa.egg - unzipped egg, namespaces: nspkg3 - nspkg3_bbb.egg - zipped egg , namespaces: nspkg3, nspkg3.bbb - nspkg3_ccc.egg - unzipped egg, namespaces: nspkg3 When using order "aaa, bbb, ccc" in PYTHONPATH, importing "nspkg3.bbb" FAILS, whereas when using order "bbb, aaa, ccc" in PYTHONPATH, importing "nspkg3.bbb" PASSES, I would expect "nspk3.bbb" to ba importable 8as a namespace package) no matter which possition it has in PYTHONPATH. How to reproduce Preperation: get hands on the eggs in question: $ wget https://github.com/pyinstaller/pyinstaller/archive/v3.5.zip $ unzip v3.5.zip $ cd pyinstaller-3.5/tests/functional/modules/nspkg3-pkg/ Order "aaa, bbb, ccc": fails $ PYTHONPATH=nspkg3_aaa.egg:nspkg3_bbb.egg:nspkg3_ccc.egg python3.7 -c "import nspkg3.bbb.zzz" Traceback (most recent call last): File "<string>", line 1, in <module> ModuleNotFoundError: No module named 'nspkg3.bbb' Order "bbb, aaa, ccc": passes: $ PYTHONPATH=nspkg3_bbb.egg:nspkg3_aaa.egg:nspkg3_ccc.egg python3.7 -c "import nspkg3.bbb.zzz" this is module nspkg3.bbb.zzz Further information I did some research and found that the zipped egg (bbb) is *not added* to the package path when using order "aaa, bbb, ccc": Order "aaa, bbb, ccc": bbb is missing here $ PYTHONPATH=nspkg3_aaa.egg:nspkg3_bbb.egg:nspkg3_ccc.egg \ python3.7 -c "import nspkg3 ; print(nspkg3.__path__)" ['…/nspkg3_aaa.egg/nspkg3', '…/nspkg3_ccc.egg/nspkg3'] Order "bbb, aaa, ccc": bbb is included $ PYTHONPATH=nspkg3_bbb.egg:nspkg3_aaa.egg:nspkg3_ccc.egg \ python3.7 -c "import nspkg3 ; print(nspkg3.__path__)" ['…/nspkg3_bbb.egg/nspkg3', '…/nspkg3_aaa.egg/nspkg3', '…/nspkg3_ccc.egg/nspkg3'] Also tested with Python 2.7: Same results ---------- components: Library (Lib) messages: 355745 nosy: htgoebel priority: normal severity: normal status: open title: pkgutil.extend_path fails with zipped eggs if not at first place type: behavior versions: Python 2.7, Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38653> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
