* Use Py_VISIT in all tp_traverse methods, instead of traversing manually orThomas Wouters2006-04-151-2/+1
| | | | | | | | using a custom, nearly-identical macro. This probably changes how some of these functions are compiled, which may result in fractionally slower (or faster) execution. Considering the nature of traversal, visiting much of the address space in unpredictable patterns, I'd argue the code readability and maintainability is well worth it ;P

* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-4/+4
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.

* Surprising fix for SF bug 563060: module can be used as base class.Guido van Rossum2002-06-041-3/+16
| | | | | | | | | | | | | | Change the module constructor (module_init) to have the signature __init__(name:str, doc=None); this prevents the call from type_new() to succeed. While we're at it, prevent repeated calling of module_init for the same module from leaking the dict, changing the semantics so that __dict__ is only initialized if NULL. Also adding a unittest, test_module.py. This is an incompatibility with 2.2, if anybody was instantiating the module class before, their argument list was probably empty; so this can't be backported to 2.2.x.

* Fix for SF bug #529050 - ModuleType.__new__ crash.Guido van Rossum2002-03-121-7/+19
| | | | | | | | | | There were several places that assumed the md_dict field was always set, but it needn't be. Fixed these to be more careful. I changed PyModule_GetDict() to initialize md_dict to a new dictionary if it's NULL. Bugfix candidate.
* Add missing "static" declarations (found by "make smelly").Neil Schemenauer2001-10-211-1/+1

* Enable GC for new-style instances. This touches lots of files, sinceGuido van Rossum2001-10-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | many types were subclassable but had a xxx_dealloc function that called PyObject_DEL(self) directly instead of deferring to self->ob_type->tp_free(self). It is permissible to set tp_free in the type object directly to _PyObject_Del, for non-GC types, or to _PyObject_GC_Del, for GC types. Still, PyObject_DEL was a tad faster, so I'm fearing that our pystone rating is going down again. I'm not sure if doing something like void xxx_dealloc(PyObject *self) { if (PyXxxCheckExact(self)) PyObject_DEL(self); else self->ob_type->tp_free(self); } is any faster than always calling the else branch, so I haven't attempted that -- however those types whose own dealloc is fancier (int, float, unicode) do use this pattern.
* Add optional docstrings to member descriptors. For backwardsGuido van Rossum2001-09-201-1/+1
| | | | | | | | | | | | | | | compatibility, this required all places where an array of "struct memberlist" structures was declared that is referenced from a type's tp_members slot to change the type of the structure to PyMemberDef; "struct memberlist" is now only used by old code that still calls PyMember_Get/Set. The code in PyObject_GenericGetAttr/SetAttr now calls the new APIs PyMember_GetOne/SetOne, which take a PyMemberDef argument. As examples, I added actual docstrings to the attributes of a few types: file, complex, instance method, super, and xxsubtype.spamlist. Also converted the symtable to new style getattr.

| | | | | | Allow module getattr and setattr to exploit string interning, via the previously null module object tp_getattro and tp_setattro slots. Yields a very nice speedup for things like random.random and os.path etc.

(This is not exactly what Vladimir posted to the patches list; I've made a few changes, and Vladimir sent me a fix in private email for a problem that only occurs in debug mode. I'm also holding back on his change to main.c, which seems unnecessary to me.)

* Access checks now work, at least for instance data (not for methodsGuido van Rossum1993-05-201-2/+3
| | | | | | | yet). The class is now passed to eval_code and stored in the current frame. It is also stored in instance method objects. An "unbound" instance method is now returned when a function is retrieved through "classname.funcname", which when called passes the class to eval_code.
* Several changes in one:Guido van Rossum1993-05-191-5/+16
| | | | | | | | | | | | | | | | (1) dictionaries/mappings now have attributes values() and items() as well as keys(); at the C level, use the new function mappinggetnext() to iterate over a dictionary. (2) "class C(): ..." is now illegal; you must write "class C: ...". (3) Class objects now know their own name (finally!); and minor improvements to the way how classes, functions and methods are represented as strings. (4) Added an "access" statement and semantics. (This is still experimental -- as long as you don't use the keyword 'access' nothing should be changed.)
