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.
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.
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?)
[ 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.
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.
(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.)
PyDict_UpdateFromSeq2(): removed it.
PyDict_MergeFromSeq2(): made it public and documented it.
PyDict_Merge() docs: updated to reveal <wink> that the second
argument can be any mapping object.
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.
