Issue #3158: doctest can now find doctests in functions and methods

Sun, 24 Nov 2013 01:19:09 -0600

Issue #3158: doctest can now find doctests in functions and methods
written in C.

As a part of this, a few doctests have been added to the builtins module
(on hex(), oct(), and bin()), a doctest has been fixed (hopefully on all
platforms) on float, and test_builtins now runs doctests in builtins.

Issue #18520: Add a new PyStructSequence_InitType2() function, same than
PyStructSequence_InitType() except that it has a return value (0 on success,
-1 on error).

Close #17694: Add minimum length to _PyUnicodeWriter

Wed, 17 Apr 2013 23:02:17 +0200

Close #17694: Add minimum length to _PyUnicodeWriter

* Add also min_char attribute to _PyUnicodeWriter structure (currently unused)
* _PyUnicodeWriter_Init() has no more argument (except the writer itself):
min_length and overallocate must be set explicitly
* In error handlers, only enable overallocation if the replacement string
is longer than 1 character
* CJK decoders don't use overallocation anymore
* Set min_length, instead of preallocating memory using
_PyUnicodeWriter_Prepare(), in many decoders
* _PyUnicode_DecodeUnicodeInternal() checks for integer overflow

Issue #14744: Use the new _PyUnicodeWriter internal API to speed up str%args and str.format(args)

Tue, 29 May 2012 12:57:52 +0200

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.

Issue #14435: Remove special block allocation code from floatobject.c

Issue #14435: Remove special block allocation code from floatobject.c
PyFloatObjects are now allocated using PyObject_MALLOC like all other
internal types, but maintain a limited freelist of objects at hand for
performance. This will result in more consistent memory usage by Python.

Sat, 18 Apr 2009 11:48:33 +0000

Issue #1869 (and 4707, 5118, 5473, 1456775): use the new
string <-> float conversion routines to make round(x, n) correctly
rounded for floats x, so that it always agrees with format(x, '.f').

Also fix some other round nuisances, like round(123.456, 1-2**31) giving
an integer rather than a float.

The other half of Issue #1580: use short float repr where possible.

Addresses the float -> string conversion, using David Gay's code which
was added in Mark Dickinson's checkin r71663.

Also addresses these, which are intertwined with the short repr
changes:

- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'
- Issue #5515: 'n' formatting with commas no longer works poorly
with leading zeros.
- PEP 378 Format Specifier for Thousands Separator: implemented
for floats.
