Chris Jerdonek 042fa653ab Issue #14783: Merge changes from 3.2. 2012-10-07 14:56:27 -07:00
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 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.

  Refactor some longobject internals:  PyLong_AsDouble and _PyLong_AsScaledDouble
  (the latter renamed to _PyLong_Frexp) now use the same core code.  The
  exponent produced by _PyLong_Frexp now has type Py_ssize_t instead of the
  previously used int, and no longer needs scaling by PyLong_SHIFT.  This
  frees the math module from having to know anything about the PyLong
  implementation.  This closes issue #5576.

  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

Mark Dickinson bd7926478d Issue #4258: Make it possible to use 30-bit digits for PyLongs:
- new configure option --enable-big-digits
 - new structseq sys.int_info giving information about the internal format
By default, 30-bit digits are enabled on 64-bit machines but
disabled on 32-bit machines.

  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.)

   digits)

  Adds a sanity check to avoid a *very rare* infinite loop due to a corrupt tls
  key list data structure in the thread startup path.

  This change is a companion to r60148 which already successfully dealt with a
  similar issue on thread shutdown.

  In particular this loop has been observed happening from this call path:
   #0  in find_key ()
   #1  in PyThread_set_key_value ()
   #2  in _PyGILState_NoteThreadState ()
   #3  in PyThreadState_New ()
   #4  in t_bootstrap ()
   #5  in pthread_start_thread ()

  I don't know how this happens but it does, *very* rarely.  On more than
  one hardware platform.  I have not been able to reproduce it manually.
  (A flaky mutex implementation on the system in question is one hypothesis).

  As with r60148, the spinning we managed to observe in the wild was due to a
  single list element pointing back upon itself.
