Serhiy Storchaka 7898043868 Issue #15989: Fix several occurrences of integer overflow 
when result of PyLong_AsLong() narrowed to int without checks.

Gregory P. Smith a689e524e7 Test for issue16772 and redoes the previous fix to accept __index__-aware 
objects as the base by using PyNumber_AsSsize_t similar to round().

Gregory P. Smith 4fbbf8c0a3 Fixes issue #16772: int() constructor second argument (base) must be an int. 
Consistent with the behavior in Python 2.

Chris Jerdonek 83fe2e1c22 Issue #14783: Improve int() docstring and also str(), range(), and slice(). 
This commit rewrites the docstring for int() to incorporate the documentation
changes made in issue #16036.  It also switches the docstrings for int(),
str(), range(), and slice() to use multi-line signatures.

Victor Stinner e577ab38ea Issue #14744: Fix compilation on Windows 2012-05-29 18:51:10 +02:00
Victor Stinner d3f0882dfb Issue #14744: Use the new _PyUnicodeWriter internal API to speed up str%args and str.format(args) 
* Formatting string, int, float and complex use the _PyUnicodeWriter API. It
   avoids a temporary buffer in most cases.
 * Add _PyUnicodeWriter_WriteStr() to restore the PyAccu optimization: just
   keep a reference to the string if the output is only composed of one string
 * Disable overallocation when formatting the last argument of str%args and
   str.format(args)
 * Overallocation allocates at least 100 characters: add min_length attribute
   to the _PyUnicodeWriter structure
 * Add new private functions: _PyUnicode_FastCopyCharacters(),
   _PyUnicode_FastFill() and _PyUnicode_FromASCII()

The speed up is around 20% in average.

Stefan Krah b77c6c65c0 Issue #12963: PyLong_AsSize_t() now returns (size_t)-1 in all error cases. 2011-09-12 16:22:47 +02:00
Nadeem Vawda 3d5881ec2b Issue #12909: Make PyLong_As* functions consistent in their use of exceptions. 
PyLong_AsDouble() and PyLong_AsUnsignedLongLong() now raise TypeError (rather
than SystemError) when passed a non-integer argument, matching the behavior of
all the other PyLong_As*() functions.

Brian Curtin dfc80e3d97 Replace Py_NotImplemented returns with the macro form Py_RETURN_NOTIMPLEMENTED.

ASCII equivalents.
