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 #8188: Introduce a new scheme for computing hashes of numbers

fractions.Fraction) that makes it easy to maintain the invariant that
hash(x) == hash(y) whenever x and y have equal value.

Issue #8748: Fix two issues with comparisons between complex and integer

Fri, 21 May 2010 14:55:26 +0000

Issue #8748: Fix two issues with comparisons between complex and integer
objects. (1) The comparison could incorrectly return True in some cases
(2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
(2) The comparison raised an OverflowError for large integers, leading
to unpredictable exceptions when combining integers and complex objects
in sets or dicts.

Patch by Meador Inge.

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.

for floats.
