New submission from Paul Moore <p.f.mo...@gmail.com>:
I am trying to write a meta path finder that "redirects" module loads to a different part of the filesystem. There's not much information in the importlib documentation, but PEP 451 says "find_spec() must return a spec with "loader" set to None (a.k.a. not set) and with submodule_search_locations set to the same portions as would have been provided by find_loader()". I have done that, and it does work as long as all parts of the namespace package are handled by the *same* metapath loader. But if I have (for instance) one portion of the namespace package handled by my finder, and want to leave the filesystem finder to handle other parts, that doesn't work. Is there a supported way to set up a finder on sys.meta_path which will expose just one "portion" of a namespace package? ---------- assignee: brett.cannon components: Documentation messages: 389997 nosy: brett.cannon, paul.moore priority: normal severity: normal status: open title: Importlib documentation does not cover how meta path finders should handle namespace packages type: behavior versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43697> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
