- Issue #2315: logging.handlers: TimedRotatingFileHandler now accounts for

daylight savings time in calculating the next rollover.

- Issue #2316: logging.handlers: TimedRotatingFileHandler now calculates

rollovers correctly even when nothing is logged for a while.

- Issue #2317: logging.handlers: TimedRotatingFileHandler now uses improved

logic for removing old files.

- Issue #2495: tokenize.untokenize now inserts a space between two consecutive

string literals; previously, ["" ""] was rendered as [""""], which is

incorrect python code.

- Issue #1681432: Add triangular distribution to the random module

- Issue #2136: urllib2's auth handler now allows single-quoted realms in the

WWW-Authenticate header.

- Issue #2434: Enhanced platform.win32_ver() to also work on Python

installation which do not have the win32all package installed.

- Added support to platform.uname() to also report the machine

and processor information on Windows XP and later. As a result,

platform.machine() and platform.processor() will report this

information as well.

- The library implementing the 2to3 conversion, lib2to3, was added

to the standard distribution.

- Issue #1747858: Fix chown to work with large uid's and gid's on 64-bit

platforms.

- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different values

on 32-bit vs. 64-bit python interpreters. Both were correct, but they now

both return a signed integer object for consistency.

- Issue #1158: add %f format (fractions of a second represented as

microseconds) to datetime objects. Understood by both strptime and

strftime.

- Issue #705836: struct.pack(">f", x) now raises OverflowError on all

platforms when x is too large to fit into an IEEE 754 float; previously

it only raised OverflowError on non IEEE 754 platforms.

- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now

optional: it defaults to the traceback of the exception that is currently

being handled (is mandatory to be in the middle of an exception, otherwise

it raises ValueError).

- Issue #1193577: A .shutdown() method has been added to SocketServers

which terminates the .serve_forever() loop.

- Bug #2220: handle rlcompleter attribute match failure more gracefully.

- Issue #2225: py_compile, when executed as a script, now returns a non-

zero status code if not all files could be compiled successfully.

- Bug #1725737: In distutil's sdist, exclude RCS, CVS etc. also in the

root directory, and also exclude .hg, .git, .bzr, and _darcs.

- Issue #1872: The struct module typecode for _Bool has been changed

from 't' to '?'.

- The bundled libffi copy is now in sync with the recently released

libffi3.0.4 version, apart from some small changes to

Modules/_ctypes/libffi/configure.ac.

On OS X, preconfigured libffi files are used.

On all linux systems the --with-system-ffi configure option defaults

to "yes".

- Issue 1577: shutil.move() now calls os.rename() if the destination is a

directory instead of copying-then-remove-source.

Tests

-----

- test_nis no longer fails when test.test_support.verbose is true and NIS is

not set up on the testing machine.

- Output comparison tests are no longer supported.

- Rewrite test_errno to use unittest and no longer be a no-op.

- GHOP 234: Convert test_extcall to doctest.

- GHOP 290: Convert test_dbm and test_dummy_threading to unittest.

- GHOP 293: Convert test_strftime, test_getargs, and test_pep247 to unittest.

- Issue #2055: Convert test_fcntl to unittest.

- Issue 1960: Convert test_gdbm to unittest.

- GHOP 294: Convert test_contains, test_crypt, and test_select to unittest.

- GHOP 238: Convert test_tokenize to use doctest.

permission to create files in the root directory.

Build

-----

- A new script 2to3 is now installed, to run the 2.x to 3.x converter.

- Python/memmove.c and Python/strerror.c have been removed; both functions are

in the C89 standard library.

C API

-----

- Patch #2477: Added PyParser_ParseFileFlagsEx() and

PyParser_ParseStringFlagsFilenameEx()

What's New in Python 2.6 alpha 1?

=================================

>>>>>>> .merge-right.r62114

- Issue #2067: file.__exit__() now calls subclasses' close() method.

- Patch #1759: Backport of PEP 3129 class decorators.

- Issue #1881: An internal parser limit has been increased. Also see

issue 215555 for a discussion.

- Added the future_builtins module, which contains hex() and oct().

These are the PEP 3127 version of these functions, designed to be

compatible with the hex() and oct() builtins from Python 3.0. They

differ slightly in their output formats from the existing, unchanged

Python 2.6 builtins. The expected usage of the future_builtins

module is:

from future_builtins import hex, oct

- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit

exponents for exponents with absolute value < 100. Follows C99

standard. This is a change on Windows, which would use 3 digits.

Also, added 'n' to the formats that PyOS_ascii_formatd understands,

so that any alterations it does to the resulting string will be

available in stringlib/formatter.h (for float.__format__).

- Implemented PEP 3101, Advanced String Formatting. This adds a new

builtin format(); a format() method for str and unicode; a

__format__() method to object, str, unicode, int, long, float, and

datetime; the class string.Formatter; and the C API

PyObject_Format().

- Fixed several potential crashes, all caused by specially crafted __del__

methods exploiting objects in temporarily inconsistent state.

>>>>>>> .merge-right.r62114

- Issue #2115: Important speedup in setting __slot__ attributes. Also

prevent a possible crash: an Abstract Base Class would try to access a slot

- Issue #1920: "while 0" statements were completely removed by the compiler,

even in the presence of an "else" clause, which is supposed to be run when

the condition is false. Now the compiler correctly emits bytecode for the

"else" suite.

- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to

``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but

it does not steal a reference to the added item.

- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro

so it can be used as an expression.

Windows

-------

- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires

Windows 2000 or greater. The _WINVER and NTDDI_VERSION macros are set to

Win2k for x86/32bit builds and WinXP for AMD64 builds.

- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE

and _CRT_NONSTDC_NO_DEPRECATE.

- Bug #1216: Restore support for Visual Studio 2002.

Mac

---

- cfmfile now raises a DeprecationWarning.

- buildtools now raises a DeprecationWarning.

- Removed the macfs module. It had been deprecated since Python 2.5. This

lead to the deprecation of macostools.touched() as it relied solely on macfs

and was a no-op under OS X.
