* Add checking for a number of metaclass error conditions.Jeremy Hylton2007-02-273-96/+197
| | | | | | | | | | | | | | | | | | | | | | | 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.

* tabifyJeremy Hylton2007-02-272-2039/+2039
| | | | | Note that ast.c still has a mix of tabs and spaces, because it attempts to use four-space indents for more of the new code.

* When printing an unraisable error, don't print exceptions. before the name.Neal Norwitz2007-02-263-3/+7

* Do not copy free variables to locals in class namespaces.Jeremy Hylton2007-02-263-19/+113
| | | | | | | | | 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.
* Fix a couple of problems in generating the AST code:Neal Norwitz2007-02-262-171/+59
| | | | | | * use %r instead of backticks since backticks are going away in Py3k * PyArena_Malloc() already sets PyErr_NoMemory so we don't need to do it again * the signature for ast2obj_int incorrectly used a bool, rather than a long

* Variation of patch # 1624059 to speed up checking if an object is a subclassNeal Norwitz2007-02-2518-22/+61
| | | | | | | | | | | | | | | | | | 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.

* Fix crash in exec when unicode filename can't be decoded.Jeremy Hylton2007-02-252-0/+3
| | | | | | | I can't think of an easy way to test this behavior. It only occurs when the file system default encoding and the interpreter default encoding are different, such that you can open the file but not decode its name.

* Update the encoding package's search function to use absolute imports whenBrett Cannon2007-02-152-2/+7
| | | | | | | | | | | | calling __import__. This helps make the expected search locations for encoding modules be more explicit. One could use an explicit value for __path__ when making the call to __import__ to force the exact location searched for encodings. This would give the most strict search path possible if one is worried about malicious code being imported. The unfortunate side-effect of that is that if __path__ was modified on 'encodings' on purpose in a safe way it would not be picked up in future __import__ calls.
