What's New in Python 2.7.2 release candidate 1?
===============================================

*Release date: 2011-05-29*

Core and Builtins
-----------------

- Issue #9670: Increase the default stack size for secondary threads on
  Mac OS X and FreeBSD to reduce the chances of a crash instead of a
  "maximum recursion depth" RuntimeError exception.
  (patch by Ronald Oussoren)

- Correct lookup of __dir__ on objects. This allows old-style classes to have
  __dir__. It also causes errors besides AttributeError found on lookup to be
  propagated.

- Issue #1195: Fix input() if it is interrupted by CTRL+d and then CTRL+c,
  clear the end-of-file indicator after CTRL+d.

- Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file
  doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int
  (length bigger than 2^31-1 bytes).

- Issue #8651: Fix "z#" format of PyArg_Parse*() function: the size was not
  written if PY_SSIZE_T_CLEAN is defined.

- Issue #9756: When calling a method descriptor or a slot wrapper descriptor,
  the check of the object type doesn't read the __class__ attribute anymore.
  Fix a crash if a class override its __class__ attribute (e.g. a proxy of the
  str type). Patch written by Andreas Stührk.

- Issue #10517: After fork(), reinitialize the TLS used by the PyGILState_*
  APIs, to avoid a crash with the pthread implementation in RHEL 5.  Patch
  by Charles-François Natali.

- Issue #6780: fix starts/endswith error message to mention that tuples are
  accepted too.

- Issue #5057: fix a bug in the peepholer that led to non-portable pyc files
  between narrow and wide builds while optimizing BINARY_SUBSCR on non-BMP
  chars (e.g. u"\U00012345"[0]).

- Issue #11650: PyOS_StdioReadline() retries fgets() if it was interrupted
  (EINTR), for example if the program is stopped with CTRL+z on Mac OS X. Patch
  written by Charles-Francois Natali.

- Issue #11144: Ensure that int(a_float) returns an int whenever possible.
  Previously, there were some corner cases where a long was returned even
  though the result was within the range of an int.

- Issue #11450: Don't truncate hg version info in Py_GetBuildInfo() when
  there are many tags (e.g. when using mq).  Patch by Nadeem Vawda.

- Issue #10451: memoryview objects could allow to mutate a readable buffer.
  Initial patch by Ross Lagerwall.

- Issue #10892: Don't segfault when trying to delete __abstractmethods__ from a
  class.

- Issue #8020: Avoid a crash where the small objects allocator would read
  non-Python managed memory while it is being modified by another thread.
  Patch by Matt Bandy.

- Issue #11004: Repaired edge case in deque.count().

- Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime()
  can now handle dates after 2038.

- Issue #4236: Py_InitModule4 now checks the import machinery directly
  rather than the Py_IsInitialized flag, avoiding a Fatal Python
  error in certain circumstances when an import is done in __del__.

- issue #11828: startswith and endswith don't accept None as slice index.
  Patch by Torsten Becker.

- Issue #10674: Remove unused 'dictmaker' rule from grammar.

- Issue #10596: Fix float.__mod__ to have the same behaviour as
  float.__divmod__ with respect to signed zeros.  -4.0 % 4.0 should be
  0.0, not -0.0.

- Issue #11386: bytearray.pop() now throws IndexError when the bytearray is
  empty, instead of OverflowError.

Library

  closed StringIO instance.

  with Tk 8.5.

  still within buffered data, and writing again).

  accepted by ``time.mktime`` and ``time.strftime`` is still system
  dependent, but ``time.mktime`` will now accept full range supported
  by the OS.  Conversion of 2-digit years to 4-digit is deprecated.
