f8387af262 Issue #4688: Add a heuristic so that tuples and dicts containing only 
untrackable objects are not tracked by the garbage collector. This can
reduce the size of collections and therefore the garbage collection overhead
on long-running programs, depending on their particular use of datatypes.

(trivia: this makes the "binary_trees" benchmark from the Computer Language
Shootout 40% faster)

0b666bfdf9 Issue #5512: speed up the long division algorithm for Python longs. 
The basic algorithm remains the same; the most significant speedups
come from the following three changes:

  (1) normalize by shifting instead of multiplying and dividing
  (2) the old algorithm usually did an unnecessary extra iteration of
      the outer loop; remove this.  As a special case, this means that
      long divisions with a single-digit result run twice as fast as
      before.
  (3) make inner loop much tighter.

Various benchmarks show speedups of between 50% and 150% for long
integer divisions and modulo operations.

6b265f1bf8 Issue 4474: On platforms with sizeof(wchar_t) == 4 and 
sizeof(Py_UNICODE) == 2, PyUnicode_FromWideChar now converts
each character outside the BMP to the appropriate surrogate pair.

Thanks Victor Stinner for the patch.

(backport of r70452 from py3k to trunk)

ed4cefbedd Fix a small nit in the error message if bool() falls back on __len__ and it returns the wrong type: it would tell the user that __nonzero__ should return bool or int. 2009-03-15 21:43:38 +00:00

6f42edb682 Issue 5237, Allow auto-numbered replacement fields in str.format() strings. 
For simple uses for str.format(), this makes the typing easier. Hopfully this
will help in the adoption of str.format().

For example:
'The {} is {}'.format('sky', 'blue')

You can mix and matcth auto-numbering and named replacement fields:
'The {} is {color}'.format('sky', color='blue')

But you can't mix and match auto-numbering and specified numbering:
'The {0} is {}'.format('sky', 'blue')
ValueError: cannot switch from manual field specification to automatic field numbering

Will port to 3.1.

2ffb26fb83 Issue #5260: Various portability and standards compliance fixes, optimizations 
and cleanups in Objects/longobject.c.  The most significant change is that
longs now use less memory:  average savings are 2 bytes per long on 32-bit
systems and 6 bytes per long on 64-bit systems.  (This memory saving already
exists in py3k.)

6a743d3694 Issue 4804. Add a function to test the validity of file descriptors on Windows, and stop using global runtime settings to silence the warnings / assertions. 2009-02-10 13:32:24 +00:00

10fe877dcd Issue #789290: make sure that hash(2**63) == hash(2.**63) on 64-bit 
platforms.  The previous code was fragile, depending on the twin
accidents that:

  (1) in C, casting the double value 2.**63 to long returns the integer
      value -2**63, and
  (2) in Python, hash(-2**63) == hash(2**63).

There's already a test for this in test_hash.
