* Enhance issubclass() and PyObject_IsSubclass() so that a tuple isWalter Dörwald2002-12-121-3/+8
| | | | | | | | | | | supported as the second argument. This has the same meaning as for isinstance(), i.e. issubclass(X, (A, B)) is equivalent to issubclass(X, A) or issubclass(X, B). Compared to isinstance(), this patch does not search the tuple recursively for classes, i.e. any entry in the tuple that is not a class, will result in a TypeError. This closes SF patch #649608.

* Document that the second argument to PyObject_IsInstanceWalter Dörwald2002-12-061-3/+7

* Change int() so that passing a string, unicode, float or long argumentWalter Dörwald2002-11-191-2/+3
| | | | | | | that is outside the integer range no longer raises OverflowError, but returns a long object instead. This fixes SF bug http://www.python.org/sf/635115
* Clarify that PyImport_AddModule() and PyImport_ExecCodeModule() don'tFred Drake2002-11-131-3/+7

* Py_InitModule() and friends now accept NULL for the 'methods'Fred Drake2002-08-141-0/+9

* 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

* 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.

* Add text on tp_as_buffer that refers tothe section that covers the topic.Fred Drake2002-04-171-3/+9

* Add more text from Guido on the type structure fields.Fred Drake2002-04-161-23/+442
| | | | Small additional changes.
* Add documentation for PyObject_Call().Fred Drake2002-04-151-0/+16
| | | | | Note that PyObject_Size() is a synonym for PyObject_Length(). This closes SF patch #544330 (contributed by Thomas Heller).

* 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.)
* Add a (very) simple description of PyType_Ready().Fred Drake2002-04-121-0/+4

* Minor clarification about what's actually promised for PyMem_Malloc(0).Tim Peters2002-04-061-6/+8
| | | | | I probably didn't do a correct thing for the LaTeX spelling of the integer 1.
