New submission from Brett Cannon <br...@python.org>: The saved_test_environment context manager should check that sys.path_hooks, sys.path_importer_cache, and __import__ have not changed.
The thing that is tricky, though, is that sys.path_importer_cache is legitimately mutated by other tests simply because valid imports put in new values. The most conservative check, then, is to validate that pre-existing keys do not change their values. A more liberal check is to whitelist finders and validate that no key have a value that is not on the whitelist. And for __import__, assigning against __builtins__.__import__ should be enough to also catch builtins.__import__. ---------- assignee: brett.cannon components: Tests keywords: easy messages: 99024 nosy: brett.cannon priority: low severity: normal stage: needs patch status: open title: regrtest should check for changes in import machinery type: feature request versions: Python 3.2 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7878> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
