[gcdebug] Only ignore weakref.WeakKeyDictionary class on Python 2 From Python 3.5, this class fails isinstance check with the following error: :: cls = <class 'weakref.WeakKeyDictionary'>, instance = <functools._lru_list_elem object at 0x7f4331859a48> def __instancecheck__(cls, instance): """Override for isinstance(instance, cls).""" # Inline the cache checking > subclass = instance.__class__ E AssertionError: [<class 'AttributeError'> in gc] 'functools._lru_list_elem' object has no attribute '__class__' /usr/lib/python3.5/abc.py:181: AssertionError I have no clue why this happens, but it makes cubicweb.web.test.test_views.AutomaticWebTest.test_startup_views fail on Python 3.5. So only consider this class for Python 2.

[wsgi] Convert "code" passed to WSGIResponse as integer WSGIResponse is passed a Request.status_out in CubicWebWSGIApplication._render(), which, starting from Python 3.5, is an instance of HTTPStatus. However, webtest still expects a 3-digits value as status string. Fortunately, calling int() on an HTTPStatus works.

[test] Add a "version" to cubicweb_mycube/__pkginfo__.py Starting from Python 3.5, unittest_cwctl.py::CubicWebCtlTC.test_list() would fail without this.

[tox] Use py3 environment instead of py34 The former would select any Python 3 interpreter.

[querier] Allow usage of computed relation into WHERE clause of write queries This used to crash because of an attempt to access unexisting table. Closes #17113286

[cleanup] Fix some flake8 errors

[tox] Bump flake8 version to 3.5 Previous patches fixed new errors raised in this version.

[pyramid] Get rid of a couple of bare "except"
