New submission from Eli Bendersky: There were numerous discussions and issues in the past about the cross-test dependencies that sometimes exist because some tests need to muck with import caches (both on the Python and C level). Some examples:
http://mail.python.org/pipermail/python-dev/2013-January/123409.html http://mail.python.org/pipermail/python-dev/2013-August/127766.html Issue #15651 is an example of a hack that has to stay in the code to allow tests to pass. Other things are also difficult - such as simulating situations where some optional modules don't exist (like pyexpat). ---- I suggest to add a capability to regrtest that will allow certain tests to request always being run inside a subprocess. Most of the infrastructure is already in place, since this is what regrtest uses to run with -jN today. An alternative would be to add some test.support utility to help with this, but then test execution would not be uniform between -j1 and -jN and also some things would be difficult to track, such as -R executions (currently all -R runs of a single test have to be within a single process for the refcount tracking to work). ---------- assignee: eli.bendersky components: Tests messages: 196793 nosy: eli.bendersky, ncoghlan, serhiy.storchaka priority: normal severity: normal status: open title: Create a way to always run tests in subprocesses within regrtest versions: Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18906> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
