Ned Deily18fae3f2013-01-31 01:24:55 -0800905- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
906 In particular, fix extension module build failures when trying to use
907 32-bit-only installer Pythons on systems with Xcode 4 (currently
908 OS X 10.8, 10.7, and optionally 10.6).
909 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
910 * Since Xcode 4 removes ppc support, extension module builds now
911 check for ppc compiler support and by default remove ppc and
912 ppc64 archs when they are not available.
913 * Extension module builds now revert to using system installed
914 headers and libs (/usr and /System/Library) if the SDK used
915 to build the interpreter is not installed or has moved.
916 * Try to avoid building extension modules with deprecated
917 and problematic Apple llvm-gcc compiler. If original compiler
918 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001269- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1270 int.__pow__. These overflow checks were causing int.__pow__ to produce
1271 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001272 compiler optimizing the check away. Also fix similar overflow checks
1273 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01001343 has left two versions of customize_compiler, the original in
1344 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001349- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1350 Distutils-based packages with C extension modules may fail because
1351 Apple has removed gcc-4.2, the version used to build python.org
1352 64-bit/32-bit Pythons. If the user does not explicitly override
1353 the default C compiler by setting the CC environment variable,
1354 Distutils will now attempt to compile extension modules with clang
1355 if gcc-4.2 is required but not found. Also as a convenience, if
1356 the user does explicitly set CC, substitute its value as the default
1357 compiler in the Distutils LDSHARED configuration variable for OS X.
1358 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1359 SDK, neither of which are available in Xcode 4. This change does not
1360 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001610- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1611 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1612 interpreter process. This could cause failures in non-Distutils subprocesses
1613 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001614 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001615 deployment target only in the environment of each build subprocess. It is
1616 still possible to globally override the default by setting
1617 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1618 greater or equal to the default value, the value with which the interpreter
1619 was built.

1648 updating the check interval, so if the user decreases the check interval,
1649 the ticker doesn't have to wind down to zero from the old starting point
1650 before the new interval takes effect. And if the user increases the
1651 interval, it makes sure the new limit takes effect right away rather have an
1652 early task switch before recognizing the new interval.

2634 becoming permanently uncollectable GC garbage. The downside is that
2635 removing __del__ means that the internal doubly-linked list has to wait for
2636 GC collection rather than freeing memory immediately when the refcnt drops
2637 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003096- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3097 start byte and the continuation byte(s) are now considered invalid, instead
3098 of the number of bytes specified by the start byte.
3099 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3100 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3101 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003110- Issue #8748: Fix two issues with comparisons between complex and integer
3111 objects. (1) The comparison could incorrectly return True in some cases
3112 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3113 (2) The comparison raised an OverflowError for large integers, leading
3114 to unpredictable exceptions when combining integers and complex objects
3115 in sets or dicts.

3255 non-float non-integer argument is now converted to an integer (if possible)
3256 using its __int__ method. Previously, only small arguments were treated this

3309 operation raises multiple signals and more than one of those signals is
3310 trapped, the specification determines the order in which the signals should be
3311 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00003456- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003457 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3458 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3459 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3479Core and Builtins
3480-----------------
3481
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003482- Issue #7301: Add environment variable $PYTHONWARNINGS.
3483
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003484- Issue #8329: Don't return the same lists from select.select when no fds are
3485 changed.
3486
Georg Brandlfee0f442010-05-22 21:26:21 +00003487- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003488 on 64-bit machines. The shift count for either left or right shift is
3489 permitted to be up to sys.maxsize.
3490
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003491- Ensure that tokenization of identifiers is not affected by locale.
3492
Georg Brandlfee0f442010-05-22 21:26:21 +00003493- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003494
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003495- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3496
Georg Brandlfee0f442010-05-22 21:26:21 +00003497- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3498 with a non-empty format string. This is an effort to future-proof user
3499 code. If a derived class does not currently implement __format__ but later
3500 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003501 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003502 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003503
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003504- Issue #8268: Old-style classes (not just instances) now support weak

3516
Victor Stinner66644262010-03-10 22:30:19 +00003517- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003518 (SIGINT). If an error occurs while importing the site module, the error is
3519 printed and Python exits. Initialize the GIL before importing the site

3534
Georg Brandlfee0f442010-05-22 21:26:21 +00003535- Issue #8257: The Decimal construct now accepts a float instance directly,
3536 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003537
3538 >>> Decimal(1.1)
3539 Decimal('1.100000000000000088817841970012523233890533447265625')
3540
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003541- collections.Counter() now supports a subtract() method.
3542
Georg Brandlfee0f442010-05-22 21:26:21 +00003543- The functools module now has a total_ordering() class decorator to simplify
3544 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003545
Georg Brandlfee0f442010-05-22 21:26:21 +00003546- The functools module also adds cmp_to_key() as a tool to transition old-style
3547 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003548
Georg Brandlfee0f442010-05-22 21:26:21 +00003549- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3550 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003551
Georg Brandlfee0f442010-05-22 21:26:21 +00003552- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3553 InvalidOperation instead of returning False. (Comparisons involving a quiet
3554 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3555 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003556
Georg Brandlfee0f442010-05-22 21:26:21 +00003557- Issue #2531: Comparison operations between floats and Decimal instances now
3558 return a result based on the numeric values of the operands; previously they
3559 returned an arbitrary result based on the relative ordering of id(float) and
3560 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003561
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003562- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003563 argument `-` which tells it to read files to compile from stdin. Each line is
3564 read on demand and the named file is compiled immediately. (Original patch by
3565 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003566
Georg Brandlfee0f442010-05-22 21:26:21 +00003567- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003570- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3571 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003572 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003573
Georg Brandlfee0f442010-05-22 21:26:21 +00003574- Comparisons using one of <, <=, >, >= between a complex instance and a
3575 Fractions instance now raise TypeError instead of returning True/False. This
3576 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3577 <=> complex, and complex <=> complex comparisons.

3919 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003920 library would return a bogus result; on Solaris, it was possible to crash the
3921 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00003934- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
3935 and add the additional members returned in an OSVERSIONINFOEX structure. The
3936 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00003939- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3940 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3941 returning NULL. The macro now returns a statically allocated empty string
3942 instead.

3952 strings,
3953 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3954 numeric strings corresponding to subnormal values,
3955 (3) a memory leak for some values large enough to cause overflow, and
3956 (4) a number of flaws that could lead to incorrectly rounded results.

3974 interpreter shutdown.
3975
Georg Brandlba83f822010-03-14 09:50:54 +00003976- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
3977 XML processing instructions and comments. These raw characters are allowed
3978 by the XML specification, and are necessary when outputting e.g. PHP code in
3979 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00003987- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003988 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003989 Also, raise ValueError rather than TypeError when an unknown TIPC address
3990 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003994- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003995 file position when calling `truncate()`. It would previously change the file
3996 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003997 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3998
Georg Brandlba83f822010-03-14 09:50:54 +00003999- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4000 class used to represent files stored inside an archive. The new
4001 implementation is significantly faster and can be wrapped in a
4002 ``io.BufferedReader`` object for more speedups. It also solves an issue
4003 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4004 Patch by Nir Aides.

4012 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00004013
Georg Brandlba83f822010-03-14 09:50:54 +00004014- Issue #7748: Since unicode values are supported for some metadata options in
4015 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4016 encoded string for them. This ensures that the upload and register commands
4017 send the correct values to PyPI without any error.

4093
Georg Brandlba83f822010-03-14 09:50:54 +00004094- The ``__complex__()`` method is now looked up on the class of instances to
4095 make it consistent with other special methods.

4099
Mark Dickinson1b34d252010-01-01 17:27:30 +00004100- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004101 DeprecationWarning when passed a float argument where an integer was expected.
4102 These functions and methods now raise TypeError instead. The majority of the
4103 effects of this change are in the extension modules, but some core functions
4104 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4105 and many unicode/str methods.

4129
Georg Brandlba83f822010-03-14 09:50:54 +00004130 These executables now work properly with the arch(1) command: ``arch -ppc
4131 python`` will start a universal binary version of python in PPC mode (unlike
4132 previous releases).

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004273

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004287
Georg Brandlba83f822010-03-14 09:50:54 +00004288- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4289 decimal string that's guaranteed to round back to x under correct rounding
4290 (with round-half-to-even rounding mode). Previously it gave a string based on
4291 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4292 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4293 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004294
Georg Brandlba83f822010-03-14 09:50:54 +00004295- Issue #7117: On almost all platforms: float-to-string and string-to-float
4296 conversions within Python are now correctly rounded. Places these conversions
4297 occur include: str for floats and complex numbers; the float and complex
4298 constructors; old-style and new-style numeric formatting; serialization and
4299 deserialization of floats and complex numbers using marshal, pickle and json;
4300 parsing of float and imaginary literals in Python code; Decimal-to-float
4301 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004302
Georg Brandlba83f822010-03-14 09:50:54 +00004303 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4304 providing correctly-rounded strtod and dtoa C functions. This code is
4305 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4306 the C compiler. There may be a small number of platforms on which correct
4307 operation of this code cannot be guaranteed, so the code is not used: notably,
4308 this applies to platforms where the C double format is not IEEE 754 binary64,
4309 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4310 and Python's configure script is unable to determine how to change the FPU
4311 precision. On these platforms conversions use the platform strtod and dtoa,
4312 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004313
Georg Brandlba83f822010-03-14 09:50:54 +00004314- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4315 uses the correctly-rounded string <-> float conversions described above (when
4316 available), and so produces correctly rounded results that will display nicely
4317 under the float repr. There are two related small changes: (1) round now
4318 accepts any class with an ``__index__()`` method for its second argument (but
4319 no longer accepts floats for the second argument), and (2) an excessively
4320 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4321 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004468- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4469 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4470 but with at least one decimal point and with a default precision
4471 of 12. Previously, the behavior the same but with a default precision of 6.
4472 This more closely matches ``str()``, and reduces surprises when adding
4473 alignment flags to the empty presentation type. This also affects the new
4474 complex.__format__ in the same way.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00004622- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
4623 file with `str' filename on Windows.
4624
Antoine Pitrouaa687902009-01-01 14:11:22 +00004625- Issue #3680: Reference cycles created through a dict, set or deque iterator
4626 did not get collected.
4627
Georg Brandlba83f822010-03-14 09:50:54 +00004628- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
4629 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00004630
Benjamin Peterson7af65562008-12-29 17:56:58 +00004631- Issue #4764: With io.open, IOError.filename is set when trying to open a
4632 directory on POSIX systems.
4633
Benjamin Petersonfe231b02008-12-29 17:47:42 +00004634- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
4635 systems.
4636
Georg Brandl6425a2f2008-12-28 11:54:53 +00004637- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004638 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00004639
Skip Montanarof205c132008-12-23 03:30:15 +00004640- Added test case to ensure attempts to read from a file opened for writing
4641 fail.
4642
Georg Brandlba83f822010-03-14 09:50:54 +00004643- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
4644 elapsed times, not only when some objects are uncollectable/unreachable.
4645 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00004657- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4658 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4659 instances. On a typical machine this saves 3 bytes of memory (on average) per
4660 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00004661
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004662- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4663 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4664 instead of throwing a MemoryError.
4665
Georg Brandlba83f822010-03-14 09:50:54 +00004666- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4667 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004668
Benjamin Petersonc078f922008-11-21 22:27:24 +00004669- Issue #4367: Python would segfault during compiling when the unicodedata
4670 module couldn't be imported and \N escapes were present.
4671
Georg Brandlba83f822010-03-14 09:50:54 +00004672- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4673 file objects with closefd=False. The file descriptor is still kept open but
4674 the file object behaves like a closed file. The ``FileIO`` object also got a
4675 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004676
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004677- Issue #4348: Some bytearray methods returned that didn't cause any change to
4678 the bytearray, returned the same bytearray instead of a copy.
4679
Georg Brandlba83f822010-03-14 09:50:54 +00004680- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00004682- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
4683
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004684- Issue #4048: The parser module now correctly validates relative imports.
4685
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004686- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
4687 exec statement.
4688
Georg Brandlba83f822010-03-14 09:50:54 +00004689- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
4690 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00004691
Benjamin Petersonbdca9422008-10-26 20:21:13 +00004692- Issue #4209: Enabling unicode_literals and the print_function in the same
4693 __future__ import didn't work.
4694
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004695- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004696 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004697
Georg Brandlba83f822010-03-14 09:50:54 +00004698- On windows, ``os.chdir()`` given unicode was not working if
4699 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4700 this code path is really executed because I cannot move to such directory on
4701 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004702
Georg Brandlba83f822010-03-14 09:50:54 +00004703- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4704 element is temporarily replaced with an equivalent frozenset. But the
4705 eventual KeyError would always report the empty ``frozenset()`` as the missing
4706 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00004707
Georg Brandlba83f822010-03-14 09:50:54 +00004708- Issue #4509: Various issues surrounding resize of bytearray objects to which
4709 there are buffer exports.

4716
Georg Brandlba83f822010-03-14 09:50:54 +00004717- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Klose91a3b9e2009-04-05 21:19:13 +00004720- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
4721 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00004722
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004723- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4724 returned them on 64bit platforms.
4725
Walter Dörwalded960ac2009-05-03 22:36:33 +00004726- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4727 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4728 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4729 of using the replace error handler in PyUnicode_DecodeUTF8().
4730
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004731- Issue #3739: The unicode-internal encoder now reports the number of characters
4732 consumed like any other encoder (instead of the number of bytes).
4733
Georg Brandlba83f822010-03-14 09:50:54 +00004734- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4735 allocator will be automatically disabled when running under Valgrind. This
4736 gives improved memory leak detection when running under Valgrind, while taking
4737 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005982- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5983 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005984 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5985 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00005990- Issue #5354: New test support function import_fresh_module() makes it easy to
5991 import both normal and optimised versions of modules. test_heapq and
5992 test_warnings have been adjusted to use it, tests for other modules with both
5993 C and Python implementations in the stdlib can be adjusted to use it over
5994 time.

Georg Brandlba83f822010-03-14 09:50:54 +00006002- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
6003 should cause a test to be skipped are now done using import_module from test
6004 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006105- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6106
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006107- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6108 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6109 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6110 ``printf`` function, whereas PyString_FromFormat has an independent
6111 implementation and uses "%zd" on all platforms for size_t values.
6112 This makes a difference on win64, where ``printf`` needs "%Id" to display
6113 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006115- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6119 object; previously an int would be returned for small values. the __long__
6120 method is allowed to return either an int or a long, but the behaviour of
6121 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006123- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006130 was correctly parsed but parsing of subsequent arguments failed.
6131
Vinay Sajip35e3b032008-09-01 14:33:59 +00006132- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006133 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6134 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6135 when given a tuple of classes as second argument, were looking up
6136 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6137 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006276What's New in Python 2.6 beta 3?
6277================================
6278
Barry Warsaw07a4a382008-08-21 01:15:08 +00006279*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006280
6281Core and Builtins
6282-----------------
6283
Guido van Rossumf8402962008-08-20 15:01:50 +00006284- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6285 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6286 extensions do not automatically benefit from the class attribute
6287 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6288 to their tp_flags field if they care. This is a backwards
6289 compatibility feature; in 3.0, all types will use the cache by
6290 default.
6291
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006292- Keyword arguments can now follow starred arguments. (``f(a, *args,
6293 keyword=23)`` is now valid syntax.)
6294
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006295- ctypes function pointers that are COM methods have a boolean True
6296 value again.
6297
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006298- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6299 by denying s# to parse objects that have a releasebuffer procedure,
6300 and introducing s*.
6301
Georg Brandl1e13ea92008-08-11 09:07:59 +00006302- Issue #3537: Fix an assertion failure when an empty but presized dict
6303 object was stored in the freelist.
6304
Mark Dickinsonb6467572008-08-04 21:30:09 +00006305- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6306 ValueError consistently across platforms.
6307
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006308- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6309 (64bit Unix, for example), unichr() would truncate its argument and return
6310 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6311
Neal Norwitze7d8be82008-07-31 17:17:14 +00006312- Apply security patches from Apple.
6313
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006314- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6315 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6316
Antoine Pitrou92f82162008-07-25 22:22:08 +00006317- Issue #1819: function calls with several named parameters are now on
6318 average 35% faster (as measured by pybench).
6319
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006320- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6321 the python debugger steps into a class statement: the free variables (local
6322 variables defined in an outer scope) would be deleted from the outer scope.
6323
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006324- Issue #2620: Overflow checking when allocating or reallocating memory
6325 was not always being done properly in some python types and extension
6326 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6327 all been updated to perform better checks and places in the code that
6328 would previously leak memory on the error path when such an allocation
6329 failed have been fixed.
6330
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006331Library
6332-------
6333
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006334- Issue #3612: Added some missing basic types in ctypes.wintypes.
6335
Benjamin Petersone977ad42008-08-20 01:42:01 +00006336- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6337 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6338
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006339- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6340 version reported by these tools does not necessarily follow the python
6341 version numbering scheme, so the module is less strict when parsing it.
6342
Nick Coghlanf70385a2008-08-18 12:42:46 +00006343- Issue #2235: Added Py3k warnings for types which will become unhashable
6344 under the stricter __hash__ inheritance rules in 3.0. Several types
6345 which did not meet the rules for hash invariants and were already
6346 unhashable in 3.0 have now been explicitly flagged as unhashable in
6347 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6348 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6349
Brett Cannon88f801d2008-08-18 00:46:22 +00006350- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6351 imported into the module but exposed as part of the module's API.
6352
Brett Cannon7b96f072008-08-18 00:41:11 +00006353- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6354
Brett Cannon46225e72008-08-18 00:36:52 +00006355- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6356
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006357- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6358
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006359- Issue #3575: Incremental decoder's decode function now takes bytearray
6360 by using 's*' instead of 't#'.
6361
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006362- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006363 fails unicode conversion on 2nd parameter. (windows only)
6364
Georg Brandl222e2082010-08-01 22:27:39 +00006365- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006366 in a redirect.
6367
Brett Cannonabe423e2008-08-16 21:47:07 +00006368- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006369 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006370
Facundo Batistaeb90b782008-08-16 14:44:07 +00006371- Issue #2776: fixed small issue when handling an URL with double slash
6372 after a 302 response in the case of not going through a proxy.
6373
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006374- Issue #2676: in the email package, content-type parsing was hanging on
6375 pathological input because of quadratic or exponential behaviour of a
6376 regular expression.
6377
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006378- Issue #3476: binary buffered reading through the new "io" library is now
6379 thread-safe.
6380
Brett Cannonbf3157b2008-08-14 05:00:03 +00006381- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6382 since mimetools itself is deprecated. Because modules are cached, all
6383 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6384
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006385- Issue #3134: shutil referenced undefined WindowsError symbol.
6386
Robert Schuppenies14646332008-08-10 11:01:53 +00006387- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6388 menu entries were not deleted.
6389
Brett Cannon83e81842008-08-09 23:30:55 +00006390- Copied the implementation of reduce() to _functools.reduce() to have a
6391 version that did not raise a DeprecationWarning under -3.
6392
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006393- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6394 a MemoryError rather than silently stop the iteration.
6395
Guido van Rossum59ce9012008-08-09 14:55:34 +00006396- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6397 to _sre.compile() will now be rejected. This should not affect anybody
6398 since the re.compile() function never generates invalid re-bytecode.
6399
Skip Montanaroa032bf42008-08-08 22:52:51 +00006400- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6401 upon first access it can be automatically initialized from the csv file if
6402 it wasn't initialized during instantiation.
6403
Brett Cannon3aa2a492008-08-06 22:28:09 +00006404- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6405 the reload() built-in has been removed.
6406
Brett Cannon7e30b672008-08-04 21:52:25 +00006407- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006408 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006409 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6410 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6411 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6412 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6413 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006414
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006415- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6416 raised an AttributeError.
6417
Benjamin Peterson01a24322008-07-28 23:35:27 +00006418- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006419 asking for a specific length. This problem only affected files opened
6420 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006421
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006422- Issue #3449: Update decimal module to use most recent specification
6423 (v. 1.68) and tests (v. 2.58) from IBM.
6424
Georg Brandl222e2082010-08-01 22:27:39 +00006425- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006426
Georg Brandl222e2082010-08-01 22:27:39 +00006427- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00006428 on a closed shelf.
6429
Georg Brandlf9efabb2008-07-23 15:16:45 +00006430- Deprecate the "ast" parser function aliases.
6431
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006432- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6433
6434- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6435 invalid arguments.
6436
6437- Issue #3302: Fix several crashes when calling locale's gettext functions
6438 with None arguments.
6439
6440- Issue #3389: Allow resolving dotted names for handlers in logging
6441 configuration files.
6442
6443- Deprecate the sunaudio module for removal in Python 3.0.
6444
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006445- Issue #3394: zipfile.writestr sets external attributes when passed a
6446 file name rather than a ZipInfo instance, so files are extracted with
6447 mode 0600 rather than 000 under Unix.
6448
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006449- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6450 argument in python 2.5, this broke code that subclassed Popen to include its
6451 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6459-------------
6460
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006461- Issue #2235: the C API function PyObject_HashNotImplemented and its
6462 interaction with the tp_hash slot (added in 2.6b2) are now documented
6463
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006464- Issue #643841: The language reference now provides more detailed
6465 coverage of the lookup process for special methods. The disclaimers
6466 regarding lack of coverage of new-style classes have also been
6467 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006470What's New in Python 2.6 beta 2?
6471================================
6472
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006473*Release date: 17-Jul-2008*
6474
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006475Core and Builtins
6476-----------------
6477
Georg Brandl3e483f62008-07-16 22:57:41 +00006478- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6479 its methods now allow for items objects that can be converted to
6480 an integer using operator.index().
6481
Mark Dickinson64b7e502008-07-16 09:40:03 +00006482- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6483 produced a ValueError instead of giving the correct float.
6484
Eric Smitha5fa5a22008-07-16 00:11:49 +00006485- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6486 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6487
Mark Dickinson7103aa42008-07-15 19:08:33 +00006488- Issue #3008: the float type has a new instance method 'float.hex'
6489 and a new class method 'float.fromhex' to convert floating-point
6490 numbers to and from hexadecimal strings, respectively.
6491
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006492- Issue #2235: __hash__ is once again inherited by default. To allow
6493 collections.Hashable to remain meaningful in the presence of the
6494 default hash implementation (object.__hash__), it is now possible
6495 to explicit block inheritance of hash by setting __hash__=None at
6496 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6497 level.
6498
Nick Coghlanb028f502008-07-13 14:52:36 +00006499- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6500 the parent module cannot be found while performing an absolute import.
6501 This means that an incorrectly defined __package__ attribute will
6502 now only prevent relative imports in that module rather than causing
6503 all imports from that module to fail.
6504
Nick Coghlan14ff9942008-07-08 14:21:42 +00006505- Issue #2517: Allow unicode messages in Exceptions again by correctly
6506 bypassing the instance dictionary when looking up __unicode__ on
6507 new-style classes.
6508
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006509- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6510 set to a custom object whose write() method happens to install
6511 another file in sys.stdout.
6512
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006513- Issue #3088: Corrected a race condition in classes derived from
6514 threading.local: the first member set by a thread could be saved in
6515 another thread's dictionary.
6516
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006517- Issue #3004: Minor change to slice.indices(): the start and stop
6518 arguments are now treated identically, making the behaviour easier
6519 to describe and understand. For example, slice(None, -10,
6520 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6521 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6522 10, -1).
6523
Georg Brandl278fc502008-07-19 12:46:12 +00006524- Issue #3219: Calling a function with repeated keyword arguments,
6525 f(a=2, a=23), would not cause a syntax error. This was a regression
6526 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006527
Georg Brandl278fc502008-07-19 12:46:12 +00006528- Issue #2862: Make int and float freelist management consistent with
6529 other freelists. Changes their CompactFreeList apis into
6530 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006531

6534
Thomas Heller57adf222008-08-14 19:10:48 +00006535- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6536 api functions without holding the GIL, which could lead to a fatal
6537 error when they failed.
6538
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006539- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006547- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6548 ForkingPickler.register() to resolve conflict with ctypes.
6549
Vinay Sajip51e65192008-07-18 09:01:10 +00006550- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00006552- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6553 a valid dlerror() message.
6554
Thomas Heller2bad6572008-07-15 17:19:50 +00006555- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6556 incomplete structure was created.
6557
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006558- Issue #3339: dummy_thread.acquire() should not return None.

6973
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006974- On MacOS X it is now possible to install the framework in 64-bit
6975 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006976 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006977
6978 This is controlled by the configure argument ``--with-universal-archs``:
6979
6980 - ``--with-universal-archs=all``: install 4-way universal
6981
6982 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6983
6984 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6985
6986 This option should be used in combination with ``--enable-universalsdk=``.
6987
6988 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7025 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007026
Christian Heimese74c8f22008-04-19 02:23:57 +00007027- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7028
Georg Brandl3ee81df2008-05-17 18:14:43 +00007029- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
7030 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007031

Georg Brandl3ee81df2008-05-17 18:14:43 +00007038- Issue #1631171: Re-implement the 'warnings' module in C (the
7039 original Python code has been kept as backup). This will allow for
7040 using the 'warning's machinery in such places as the parser where
7041 use of pure Python code is not possible. Both the ``showarning()``
7042 and ``formatwarning()`` gain an optional 'line' argument which is
7043 not called by default for backwards-compatibility reasons. Setting
7044 ``warnings.showwarning()`` to an implementation that lacks support
7045 for the ``line`` argument will raise a DeprecationWarning.

7069
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007070- The getpass module has been improved on Unix. It now uses /dev/tty
7071 by default and uses stderr instead of stdout. A GetPassWarning is
7072 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007073

Georg Brandl3ee81df2008-05-17 18:14:43 +00007087- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007088 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007108- Issue #2550: The approach used by client/server code for obtaining
7109 ports to listen on in network-oriented tests has been refined in an
7110 effort to facilitate running multiple instances of the entire
7111 regression test suite in parallel without issue.
7112 test_support.bind_port() has been fixed such that it will always
7113 return a unique port -- which wasn't always the case with the
7114 previous implementation, especially if socket options had been set
7115 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7116 new implementation of bind_port() will actually raise an exception
7117 if it is passed an AF_INET/SOCK_STREAM socket with either the
7118 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7119 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7120 the socket it's been passed. This currently only applies to
7121 Windows. This option prevents any other sockets from binding to the
7122 host/port we've bound to, thus removing the possibility of the
7123 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7124 when a second SOCK_STREAM socket binds and accepts to a host/port
7125 that's already been bound by another socket. The optional preferred
7126 port parameter to bind_port() has been removed. Under no
7127 circumstances should tests be hard coding ports!
7128
7129 test_support.find_unused_port() has also been introduced, which will
7130 pass a temporary socket object to bind_port() in order to obtain an
7131 unused port. The temporary socket object is then closed and
7132 deleted, and the port is returned. This method should only be used
7133 for obtaining an unused port in order to pass to an external program
7134 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7135 a parameter to a server-oriented class that doesn't give you direct
7136 access to the underlying socket used.
7137
7138 Finally, test_support.HOST has been introduced, which should be used
7139 for the host argument of any relevant socket calls (i.e. bind and
7140 connect).

7145 test_asynchat and test_socket_ssl.
7146

7148 suite to run in parallel without issue.

7416
Fred Drakea8ee94b2008-03-01 02:45:07 +00007417- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007418 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007419
Georg Brandlad61bc82008-02-23 15:11:18 +00007420- Issue #2067: file.__exit__() now calls subclasses' close() method.
7421
7422- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007423
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007424- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007425 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007426
Eric Smitha73fbe72008-02-23 03:09:44 +00007427- Added the future_builtins module, which contains hex() and oct().
7428 These are the PEP 3127 version of these functions, designed to be
7429 compatible with the hex() and oct() builtins from Python 3.0. They
7430 differ slightly in their output formats from the existing, unchanged
7431 Python 2.6 builtins. The expected usage of the future_builtins
7432 module is:
7433 from future_builtins import hex, oct
7434
Eric Smith7ef40bf2008-02-20 23:34:22 +00007435- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7436 exponents for exponents with absolute value < 100. Follows C99
7437 standard. This is a change on Windows, which would use 3 digits.
7438 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7439 so that any alterations it does to the resulting string will be
7440 available in stringlib/formatter.h (for float.__format__).
7441
Eric Smith5a3c1352008-02-19 13:21:56 +00007442- Implemented PEP 3101, Advanced String Formatting. This adds a new
7443 builtin format(); a format() method for str and unicode; a
7444 __format__() method to object, str, unicode, int, long, float, and
7445 datetime; the class string.Formatter; and the C API
7446 PyObject_Format().
7447
Georg Brandl3ee81df2008-05-17 18:14:43 +00007448- Fixed several potential crashes, all caused by specially crafted
7449 __del__ methods exploiting objects in temporarily inconsistent
7450 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007451
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007452- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007453 prevent a possible crash: an Abstract Base Class would try to access
7454 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007455
Georg Brandl3ee81df2008-05-17 18:14:43 +00007456- Fixed repr() and str() of complex numbers with infinity or nan as
7457 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007458
Georg Brandl3ee81df2008-05-17 18:14:43 +00007459- Clear all free lists during a gc.collect() of the highest generation
7460 in order to allow pymalloc to free more arenas. Python may give back
7461 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007462
Georg Brandl3ee81df2008-05-17 18:14:43 +00007463- Issue #2045: Fix an infinite recursion triggered when printing a
7464 subclass of collections.defaultdict, if its default_factory is set
7465 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007466
Christian Heimesf75dbef2008-02-08 00:11:31 +00007467- Fixed a minor memory leak in dictobject.c. The content of the free
7468 list was not freed on interpreter shutdown.
7469
Georg Brandl21e99f42010-03-07 15:23:59 +00007470- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007471 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007472
Georg Brandl3ee81df2008-05-17 18:14:43 +00007473- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7474 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007475 to compact the internal free lists of pre-allocted ints and floats.
7476
Georg Brandl3ee81df2008-05-17 18:14:43 +00007477- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7478 calls. Python expected the return type int but the fork familie
7479 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007480
Georg Brandl3ee81df2008-05-17 18:14:43 +00007481- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7482 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007483
Georg Brandl3ee81df2008-05-17 18:14:43 +00007484- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7485 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007486

7488 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007489
Georg Brandl3ee81df2008-05-17 18:14:43 +00007490- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7491 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007492
Georg Brandl3ee81df2008-05-17 18:14:43 +00007493- Patch #1473257: generator objects gain a gi_code attribute. This is
7494 the same object as the func_code attribute of the function that
7495 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007496
Georg Brandl3ee81df2008-05-17 18:14:43 +00007497- Issue #1920: "while 0" statements were completely removed by the
7498 compiler, even in the presence of an "else" clause, which is
7499 supposed to be run when the condition is false. Now the compiler
7500 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007501
Guido van Rossumeead05f2008-01-24 18:21:02 +00007502- A few crashers fixed: weakref_in_del.py (issue #1377858);
7503 loosing_dict_ref.py (issue #1303614, test67.py);
7504 borrowed_ref_[34].py (not in tracker).
7505
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007506- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007507 suppressed while an extension is loaded by calling SetErrorMode in
7508 dynload_win.c. The error is still reported properly.
7509
Georg Brandl3ee81df2008-05-17 18:14:43 +00007510- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007511 several extension methods and modules do not work without unicode
7512 support.
7513
Georg Brandl26543b12008-01-21 18:36:51 +00007514- Issue #1882: when compiling code from a string, encoding cookies in the
7515 second line of code were not always recognized correctly.
7516
Georg Brandl14404b62008-01-19 19:27:05 +00007517- Issue #1679: "0x" was taken as a valid integer literal.
7518
Georg Brandl6caad7d2008-01-26 14:19:22 +00007519- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007520 added.
7521
Christian Heimesc94e2b52008-01-14 04:13:37 +00007522- sys.float_info / PyFloat_GetInfo: The floating point information
7523 object was converted from a dict to a specialized structseq object.
7524
Georg Brandl3ee81df2008-05-17 18:14:43 +00007525- Patch #1816: Added sys.flags structseq. It exposes the status of
7526 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007527
Georg Brandl3ee81df2008-05-17 18:14:43 +00007528- Objects/structseq.c: Implemented new structseq representation. The
7529 patch makes structseqs (e.g. the return value of os.stat) more
7530 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007531
Georg Brandl3ee81df2008-05-17 18:14:43 +00007532- Patch #1700288: added a type attribute cache that caches method
7533 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007534
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007535- Bug #1776: __import__() no longer accepts filenames on any platform.

7539
Georg Brandl3ee81df2008-05-17 18:14:43 +00007540- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7541 envvar and sys.dont_write_bytecode attribute. All these can be set
7542 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007543
Georg Brandl3ee81df2008-05-17 18:14:43 +00007544- Improve some exception messages when Windows fails to load an
7545 extension module. Now we get for example '%1 is not a valid Win32
7546 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007547
Georg Brandl3ee81df2008-05-17 18:14:43 +00007548- Bug #1481296: Fixed long(float('nan')) != 0L.

7551 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007552
Christian Heimes0a8143f2007-12-18 23:22:54 +00007553- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007554 and INF. float("nan"), float("inf") and float("-inf") now work on
7555 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007556
Georg Brandl3ee81df2008-05-17 18:14:43 +00007557- Compiler now generates simpler and faster code for dictionary
7558 literals. The oparg for BUILD_MAP now indicates an estimated
7559 dictionary size. There is a new opcode, STORE_MAP, for adding
7560 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007594- Issue #1265: Fix a problem with sys.settrace, if the tracing
7595 function uses a generator expression when at the same time the
7596 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007597
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007598- sets and frozensets now have an isdisjoint() method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007605 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7606 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007607
Georg Brandl3ee81df2008-05-17 18:14:43 +00007608- Issue #1686386: Tuple's tp_repr did not take into account the
7609 possibility of having a self-referential tuple, which is possible
7610 from C code. Nor did object's tp_str consider that a type's tp_str
7611 could do something that could lead to an inifinite recursion.
7612 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7613 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007614
Georg Brandl3ee81df2008-05-17 18:14:43 +00007615- Issue #1164: It was possible to trigger deadlock when using the

7617 as needed. Now PyObject_Print() does the right thing along with
7618 various tp_print implementations of the built-in types and those in
7619 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007621- Issue #1147: Exceptions were directly allowing string exceptions in
7622 their throw() method even though string exceptions no longer
7623 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007625- Issue #1096: Prevent a segfault from getting the repr of a very
7626 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00007628- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007629 PyObject_Call() never calling back out to Python code to trigger
7630 recursion depth updates/checks. Required the creation of a static
7631 RuntimeError instance in case normalizing an exception put the
7632 recursion check value past its limit. Fixes crashers
7633 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007648- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007649 __*__ attributes. (Some already existed, e.g., __doc__ and
7650 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007651
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007652- Add -3 option to the interpreter to warn about features that are

7656 calls.
7657
Collin Winter62903052007-05-18 23:11:24 +00007658- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007659 "except E as target:". This is to provide forwards compatibility
7660 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007661
Brett Cannon229cee22007-05-05 01:34:02 +00007662- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007667- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007668 setting a plain string, ie don't expand to single letter identifiers.
7669
Raymond Hettinger13936692007-04-11 18:40:58 +00007670- Request #1191699: Slices can now be pickled.
7671
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007672- Request #1193128: str.translate() now allows a None argument for
7673 translations that only remove characters without re-mapping the
7674 remaining characters.
7675
Georg Brandl5cb76c12007-03-21 09:00:39 +00007676- Patch #1682205: a TypeError while unpacking an iterable is no longer

7680
Guido van Rossum143b5642007-03-23 04:58:42 +00007681- Bug #1683368: The object.__init__() and object.__new__() methods are
7682 now stricter in rejecting excess arguments. The only time when
7683 either allows excess arguments is when it is not overridden and the
7684 other one is. For backwards compatibility, when both are
7685 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007686 warning later). Also, type.__init__() insists on the same signature
7687 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007688
Georg Brandl3ee81df2008-05-17 18:14:43 +00007689- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7690 object to complex using its __complex__() method before falling back
7691 to the __float__() method. Therefore, the functions in the cmath
7692 module now can operate on objects that define a __complex__()
7693 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007711- Bug #1678647: write a newline after printing an exception in any
7712 case, even when converting the value to a string failed.
7713
Georg Brandl871f1bc2007-03-12 13:17:36 +00007714- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715 its argument, if it exists. If not, it will work like before. This
7716 allows customizing the output of dir() in the presence of a
7717 __getattr__().

7726 parthensized forms. This means complex(repr(x)) now works instead of
7727 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007728
Georg Brandlaa2321b2007-03-07 00:40:28 +00007729- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007730 makes the filenames the warning module prints much more sensible
7731 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007744- Patch #1674228: when assigning a slice (old-style), check for the
7745 sq_ass_slice instead of the sq_slice slot.
7746
Georg Brandl3ee81df2008-05-17 18:14:43 +00007747- When printing an unraisable error, don't print exceptions. before

8358 Python would crash instead of raising an error.
8359

8375 accepted in TestSuite.addTest(). This should cause no
8376 incompatibility since it never made sense with ordinary subclasses
8377 -- the failure just occurred later, with a more cumbersome
8378 exception.

8656 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008657
Georg Brandl3ee81df2008-05-17 18:14:43 +00008658- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008659 that the SMTP.starttls() caller no longer needs to call ehlo()
8660 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008661 does not claim to support starttls. Adds the
8662 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00008761 time so that opening a database previously created with the DB_DUP
8762 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8763 opens. Specifically: dictionary assignment to a DB object will
8764 replace all values for a given key when the database allows
8765 duplicate values. DB users should use DB.put(k, v) when they want
8766 to store duplicates; not DB[k] = v.

8773 characters with ASCII value less than 32. Also, it correctly quotes
8774 dots only if they occur on a single line, as opposed to the previous
8775 behavior of quoting dots if they are the second character of any
8776 line.

9108-----
9109
Georg Brandl3ee81df2008-05-17 18:14:43 +00009110- Unified naming convention for free lists and their limits. All free
9111 lists in Object/ are named ``free_list``, the counter ``numfree``
9112 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9113 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009114
Georg Brandl3ee81df2008-05-17 18:14:43 +00009115- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9116 to ``PyTuple_SetItem``, it can be used to populate a brand new
9117 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009118
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009119- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009121- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9122 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9123 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009124
9125- Patch #1720595: add T_BOOL to the range of structmember types.
9126
9127- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9128 ``PyFloat_GetInfo()`` to the float API.
9129
Georg Brandl3ee81df2008-05-17 18:14:43 +00009130- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9131 of w# format code incorrectly truncated the length to an int, even
9132 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9133 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009134
Georg Brandl3ee81df2008-05-17 18:14:43 +00009135- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9136 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009138- PEP 3123: Provide forward compatibility with Python 3.0, while
9139 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9140 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009141
Georg Brandl3ee81df2008-05-17 18:14:43 +00009142- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9143 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009144
9145- Patch #1733960: Allow T_LONGLONG to accept ints.
9146
9147- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9148

9152
9153- Fix some leftovers from the conversion from int to Py_ssize_t
9154 (relevant to strings and sequences of more than 2**31 items).
9155
9156- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9157 outside of pystate.c and should not be necessary.
9158
Georg Brandl3ee81df2008-05-17 18:14:43 +00009159- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9160 absolute imports. In earlier versions they might have used relative
9161 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009162
Georg Brandl3ee81df2008-05-17 18:14:43 +00009163- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9164 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009165
Georg Brandl3ee81df2008-05-17 18:14:43 +00009166- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
9167 macro so it can be used as an expression.

9172
Georg Brandl3ee81df2008-05-17 18:14:43 +00009173- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9174 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9175 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9176 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009177
Georg Brandl3ee81df2008-05-17 18:14:43 +00009178- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00009191- Removed the macfs module. It had been deprecated since Python 2.5.
9192 This lead to the deprecation of macostools.touched() as it relied
9193 solely on macfs and was a no-op under OS X.
