* Add a type.__init__() method that enforces the same signature asGuido van Rossum2007-03-231-1/+34
| | | | | | | | | type.__new__(), and then calls object.__init__(cls), just to be anal. This allows us to restore the code in string.py's _TemplateMetaclass that called super(...).__init__(name, bases, dct), which I commented out yesterday since it broke due to the stricter argument checking added to object.__init__().
* - Bug #1683368: The object.__init__() and object.__new__() methods areGuido van Rossum2007-03-231-12/+88
| | | | | | | | | | | | | now stricter in rejecting excess arguments. The only time when either allows excess arguments is when it is not overridden and the other one is. For backwards compatibility, when both are overridden, it is a deprecation warning (for now; maybe a Py3k warning later). When merging this into 3.0, the warnings should become errors. Note: without the change to string.py, lots of spurious warnings happen. What's going on there?

* Add checking for a number of metaclass error conditions.Jeremy Hylton2007-02-271-32/+94
| | | | | | | | | | | | | | | | | | | | | | | We add some new rules that are required for preserving internal invariants of types. 1. If type (or a subclass of type) appears in bases, it must appear before any non-type bases. If a non-type base (like a regular new-style class) occurred first, it could trick type into allocating the new class an __dict__ which must be impossible. 2. There are several checks that are made of bases when creating a type. Those checks are now repeated when assigning to __bases__. We also add the restriction that assignment to __bases__ may not change the metaclass of the type. Add new tests for these cases and for a few other oddball errors that were no previously tested. Remove a crasher test that was fixed. Also some internal refactoring: Extract the code to find the most derived metaclass of a type and its bases. It is now needed in two places. Rewrite the TypeError checks in test_descr to use doctest. The tests now clearly show what exception they expect to see.

| | | | | | | | | Fixes bug 1569356, but at the cost of a minor incompatibility in locals(). Add test that verifies that the class namespace is not polluted. Also clarify the behavior in the library docs. Along the way, cleaned up the dict_to_map and map_to_dict implementations and added some comments that explain what they do.

* Variation of patch # 1624059 to speed up checking if an object is a subclassNeal Norwitz2007-02-259-9/+30
| | | | | | | | | | | | | | | | | | of some of the common builtin types. Use a bit in tp_flags for each common builtin type. Check the bit to determine if any instance is a subclass of these common types. The check avoids a function call and O(n) search of the base classes. The check is done in the various Py*_Check macros rather than calling PyType_IsSubtype(). All the bits are set in tp_flags when the type is declared in the Objects/*object.c files because PyType_Ready() is not called for all the types. Should PyType_Ready() be called for all types? If so and the change is made, the changes to the Objects/*object.c files can be reverted (remove setting the tp_flags). Objects/typeobject.c would also have to be modified to add conditions for Py*_CheckExact() in addition to each the PyType_IsSubtype check.

* SF patch #1630975: Fix crash when replacing sys.stdout in sitecustomizeThomas Wouters2007-01-231-0/+2
| | | | | | | | | | | When running the interpreter in an environment that would cause it to set stdout/stderr/stdin's encoding, having a sitecustomize that would replace them with something other than PyFile objects would crash the interpreter. Fix it by simply ignoring the encoding-setting for non-files. This could do with a test, but I can think of no maintainable and portable way to test this bug, short of adding a sitecustomize.py to the buildsystem and have it always run with it (hmmm....)
