* New functions for extension writers on Windows:Thomas Heller2002-07-291-0/+16
| | | | | | | | | | PyErr_SetExcFromWindowsErr(), PyErr_SetExcFromWindowsErrWithFilename(). Similar to PyErr_SetFromWindowsErrWithFilename() and PyErr_SetFromWindowsErr(), but they allow to specify the exception type to raise. Available on Windows. See SF patch #576458.

* The Py_REF_DEBUG/COUNT_ALLOCS/Py_TRACE_REFS macro minefield: addedTim Peters2002-07-091-1/+1
| | | | | | | | | | | | | | | | | | | | | more trivial lexical helper macros so that uses of these guys expand to nothing at all when they're not enabled. This should help sub- standard compilers that can't do a good job of optimizing away the previous "(void)0" expressions. Py_DECREF: There's only one definition of this now. Yay! That was that last one in the family defined multiple times in an #ifdef maze. Py_FatalError(): Changed the char* signature to const char*. _Py_NegativeRefcount(): New helper function for the Py_REF_DEBUG expansion of Py_DECREF. Calling an external function cuts down on the volume of generated code. The previous inline expansion of abort() didn't work as intended on Windows (the program often kept going, and the error msg scrolled off the screen unseen). _Py_NegativeRefcount calls Py_FatalError instead, which captures our best knowledge of how to abort effectively across platforms.

* This is my nearly two year old patchMichael W. Hudson2002-06-111-0/+26
| | | | | | | | | [ 400998 ] experimental support for extended slicing on lists somewhat spruced up and better tested than it was when I wrote it. Includes docs & tests. The whatsnew section needs expanding, and arrays should support extended slices -- later.

* Typo: whcar_t should be wchar_t.Thomas Heller2002-04-291-4/+4
| | | | Bugfix candidate? Don't know how this is handled in the docs.

* Repair widespread misuse of _PyString_Resize. Since it's clear peopleTim Peters2002-04-271-1/+10
| | | | | | | | | | | | | | | | | | | | | | don't understand how this function works, also beefed up the docs. The most common usage error is of this form (often spread out across gotos): if (_PyString_Resize(&s, n) < 0) { Py_DECREF(s); s = NULL; goto outtahere; } The error is that if _PyString_Resize runs out of memory, it automatically decrefs the input string object s (which also deallocates it, since its refcount must be 1 upon entry), and sets s to NULL. So if the "if" branch ever triggers, it's an error to call Py_DECREF(s): s is already NULL! A correct way to write the above is the simpler (and intended) if (_PyString_Resize(&s, n) < 0) goto outtahere; Bugfix candidate.

* Warn people away from PyModule_GetDict(), but not too strongly.Fred Drake2002-04-121-0/+3
| | | | | | | (The real issue is whether modules can benefit from an alternate implementation strategy rather than using a dictionary. We should migrate away from direct dictionary manipulation to allow more room for Jeremy to flex the implementation with changes in globals lookup.)

| | | | | I probably didn't do a correct thing for the LaTeX spelling of the integer 1.
* Move reference material on PyArg_Parse*() out of the Extending & EmbeddingFred Drake2002-04-052-110/+415
| | | | | | | | document to the C API reference. Move some instructional text from the API reference to the Extending & Embedding manual. Fix the descriptions of the es and es# formats for PyArg_Parse*(). This closes SF bug #536516.
* Correct the descriptions of the PyObject_As*Buffer() return values.Fred Drake2002-04-041-6/+6
| | | | This closes SF bug #539081.
* Introduce two new flag bits that can be set in a PyMethodDef methodFred Drake2002-03-281-2/+30
| | | | | | | | | | | | | | | | | | | descriptor, as used for the tp_methods slot of a type. These new flag bits are both optional, and mutually exclusive. Most methods will not use either. These flags are used to create special method types which exist in the same namespace as normal methods without having to use tedious construction code to insert the new special method objects in the type's tp_dict after PyType_Ready() has been called. If METH_CLASS is specified, the method will represent a class method like that returned by the classmethod() built-in. If METH_STATIC is specified, the method will represent a static method like that returned by the staticmethod() built-in. These flags may not be used in the PyMethodDef table for modules since these special method types are not meaningful in that case; a ValueError will be raised if these flags are found in that context.
