Fred Drake 7a700b873b clean up indexing for None, NotImplemented
closes SF bug #820344

Andrew MacIntyre f72af655c5 At 2.2, the Py<type>_Check() family of API functions (macros) changed
semantics to include subtypes.  Most concrete object APIs then had
a Py<type>_CheckExact() macro added to test for an object's type
not including subtypes.

The PyDict_CheckExact() macro wasn't created at that time, so I've added
it for API completeness/symmetry - even though nobody has complained
about its absence in the time since 2.2 was released.

Not a backport candidate.

Andrew MacIntyre 13cd8898d2 The semantics of PyList_Check() and PyDict_Check() changed at 2.2, along
with most other concrete object checks, but the docs weren't brought into
line.

PyList_CheckExact() was added at 2.2 but never documented.

backport candidate.

Raymond Hettinger 5469324cde Note that \var{ppos} values are not consecutive and should not be altered. 2003-12-13 19:48:41 +00:00
Raymond Hettinger bc0f2ab9bb Expose dict_contains() and PyDict_Contains() with is about 10% faster
than PySequence_Contains() and more clearly applicable to dicts.

Apply the new function in setobject.c where __contains__ checking is
ubiquitous.

Raymond Hettinger cb2da43db8 Extended tuple's C API to include a new function, PyTuple_Pack() that is
useful for rapidly building argument tuples without having to invoke the
more sophisticated machinery of Py_BuildValue().

Skip Montanaro 1ff49a7734 * Add description of PyInt_FromString.
* Correct description of PyFloat_FromString.  While ignored, the pend
  argument still has to be given.
* Typo in PyLong_FromString.

Skip Montanaro ae31e9b8c7 Add PyFloat_FromString. Left the char **pend argument out of the
description since while there, it is useless and ignored, according to Tim's
commen.  (PyInt_FromString is also not described, but PyLong_FromString is.
Is the former deprecated?)

Michael W. Hudson 5efaf7eac8 This is my nearly two year old patch
[ 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.

Thomas Heller 541703b18f Typo: whcar_t should be wchar_t.
Bugfix candidate? Don't know how this is handled in the docs.

Tim Peters 5de9842b34 Repair widespread misuse of _PyString_Resize. Since it's clear people
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.

Fred Drake f495ef7466 Warn people away from PyModule_GetDict(), but not too strongly.
(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.)

Fred Drake 6ccdccd35d Add a note that Py_None needs the same reference count treatment as any
other PyObject *.

Fred Drake 3adf79e3e2 Break the Python/C API manual into smaller files by chapter. This manual
has grown beyond what font-lock will work with using the default (X)Emacs
settings.

Indentation of the description has been made consistent, and a number of
smaller markup adjustments have been made as well.
