Some checks in the C code are done to avoid modification by the user of builtin classes. Unfortunately this also affects C-extension classes. Since addition of the hackcheck, this is more and more difficult to write a not too obscure workaround for extension classes. Moreover the HeapType flag is used far beyond its original purpose, as described in object.h. The proposed change is to add a new flag, "Modifiable" that indicates if the class can be modified by the python user ( ie if he can set attributes, change classes, change bases). Builtins won't have it, heaptype objects will always have it and extension classes can chose. The flag addition is backward compatible, and binary compatible. |

Logged In: YES user_id=21627 Can you please give an example of a problem solved by this patch? What is the extension type, what code would the user like to execute, and what error is reported on an attempt to do so? |
