Cc:ing pypy-dev back in, assuming it's omission was just a slip... (also why I'm not snipping the quoted material).

Running CPython unittests on PyPy
by Seo Sanghyeon July 14, 2004

July 14, 2004

Today I could run CPython unittests on top of PyPy. test_call is passed. :-) Some problems: 1) For some reason, test_support complains if not imported from test package. Error message is: ImportError: test_support must be imported from the test package 2) PyPy's sys.path includes appspace/ and interpreter/. And they have their own test/ subdirectory, thus breaking import from test package. 3) PyPy methods have no __doc__. CPython methods always have __doc__, even if it is None. This … [View More]

die cpythonobject, die!
by Michael Hudson July 14, 2004

July 14, 2004

This surprisingly brief patch removes all uses of W_CPythonObject (though not all uses of W_BuiltinFunctionObject), by using the 'automatically faking non re-implementations' technique I've talked about before. Trying to finish the job -- i.e. removing use of W_BuiltinFunctionObject wrappers for slot wrappers -- gave me infinite recursions and a headache. Thoughts? Cheers, mwh -- Good? Bad? Strap him into the IETF-approved witch-dunking apparatus immediately! … [View More]

Unbound method must be called with instance as first argument
by Seo Sanghyeon July 13, 2004

July 13, 2004

Consider following testcase: class C: pass class D(C): pass def m(self): return self C.m = m D.m = C.m print C().m() print D().m() CPython runs it okay, but PyPy baffles and raises TypeError, with message ${SUBJ}. Changing 5th line to "D.m = m" and it runs fine. The point is, "D.m = C.m" should transform C.m from unbound method of class C to unbound method of class D... This breaks mailbox.py, among other things. Read how PortableUnixMailbox is implemented there. Regards,

Squeak is written in itself

Hi there, I just ran into this. Quite possibly you are all fully aware of this already, but sounds similar to PyPy in some of its approaches. I haven't read the full article yet: http://www.cosc.canterbury.ac.nz/~wolfgang/cosc205/squeak.html Has a horribly hard to read background image, ugh.. Regards, Martijn

New style classes
by Richard Emslie July 12, 2004

July 12, 2004

Hi PyPy ers, I was wondering why we use old style classes everywhere in the pypy code base - esp since pypy only supports new style classes (!). Would anyone have a huge objection to making ObjSpace a new style class? (Needed for the trace object space) Also in CPython you can class A(object): pass class B(object): pass a = A() a.__class__ = B but in PyPy we get "AttributeError: read-only attribute". Is this just a TODO, or is it a feature? ;-) Cheers, Richard

Over here we have somebody who likes to write unittests like this: def test_sys_in_modules(self): import sys modules = sys.modules self.failUnless('sys' in modules, "An entry for sys " "is not in sys.modules.") sys2 = sys.modules['sys'] self.failUnless(sys is sys2, "import sys is not sys.modules[sys].") def test_builtin_in_modules(self): import sys modules = sys.modules self.… [View More]
