[issue8269] Missing return values for PyUnicode C/API functions

[Torsten Becker]

Torsten Becker torsten.bec...@gmail.com added the comment:

Hi, I read through unicodeobject.c and added the (IMO) proper reference counts 
to the missing functions.  I attached a first patch which adds this to 
Doc/data/refcounts.dat.

The patch also fixes 2 minor glitches in Doc/c-api/unicode.rst, 
PyUnicode_DecodeMBCSStateful stated int instead of Py_ssize_t for it's 
arguments and PyUnicode_FromString had it's return value wrongly formated.

I'd like to add that a patch would need to modify Doc/data/refcounts.dat, not 
the .rst files.

if you are referring to 
http://docs.python.org/dev/py3k/c-api/unicode.html#PyUnicode_FromFormat the 
return type is a PyObject.

See also http://docs.python.org/dev/py3k/c-api/structures.html#PyObject

[issue8269] Missing return values for PyUnicode C/API functions

[Arnaud Fontaine]

Arnaud Fontaine ar...@debian.org added the comment:

I meant whether it returns a new reference or not. For instance, documentation 
for PyUnicode_FromObject() and PyUnicode_AsWideChar() states that a new 
reference is returned, but this is most specified for most functions in Unicode 
Object (at least).

Patches are welcome !

FWIW: Unless otherwise noted, all Unicode APIs that return a PyObject*
give you a new reference.

[issue8269] Missing return values for PyUnicode C/API functions

[Arnaud Fontaine]

New submission from Arnaud Fontaine ar...@debian.org:

For example, PyUnicode_FromFormat() does not specify the return value but it 
does not seem to be only one. I only have a basic knowledge of Python C/API, so 
I am not sure whether it is meaningful.
