427 incorrect results with recent versions of Clang, as a result of the

429 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +0100505- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
506 Distutils-based packages with C extension modules may fail because
507 Apple has removed gcc-4.2, the version used to build python.org
508 64-bit/32-bit Pythons. If the user does not explicitly override
509 the default C compiler by setting the CC environment variable,
510 Distutils will now attempt to compile extension modules with clang
511 if gcc-4.2 is required but not found. Also as a convenience, if
512 the user does explicitly set CC, substitute its value as the default
513 compiler in the Distutils LDSHARED configuration variable for OS X.
514 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
515 SDK, neither of which are available in Xcode 4. This change does not
516 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700789- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
790 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
791 interpreter process. This could cause failures in non-Distutils subprocesses
792 and was unreliable since tests or user programs could modify the interpreter
793 environment after Distutils set it. Instead, have Distutils set the the
794 deployment target only in the environment of each build subprocess. It is
795 still possible to globally override the default by setting
796 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
797 greater or equal to the default value, the value with which the interpreter
798 was built.

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

1781
Raymond Hettinger20397532010-09-12 02:11:45 +00001782- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1783 This prevents user-created self-referencing ordered dictionaries from
1784 becoming permanently uncollectable GC garbage. The downside is that
1785 removing __del__ means that the internal doubly-linked list has to wait for
1786 GC collection rather than freeing memory immediately when the refcnt drops
1787 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002246- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

2249 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2250 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

2261 objects. (1) The comparison could incorrectly return True in some cases
2262 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002607 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2608 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2609 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2629Core and Builtins
2630-----------------
2631
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002632- Issue #7301: Add environment variable $PYTHONWARNINGS.
2633
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002634- Issue #8329: Don't return the same lists from select.select when no fds are
2635 changed.
2636
Georg Brandlfee0f442010-05-22 21:26:21 +00002637- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002638 on 64-bit machines. The shift count for either left or right shift is
2639 permitted to be up to sys.maxsize.
2640
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002641- Ensure that tokenization of identifiers is not affected by locale.
2642
Georg Brandlfee0f442010-05-22 21:26:21 +00002643- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002644
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002645- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2646
Georg Brandlfee0f442010-05-22 21:26:21 +00002647- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2648 with a non-empty format string. This is an effort to future-proof user
2649 code. If a derived class does not currently implement __format__ but later
2650 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002651 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002652 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002653
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002654- Issue #8268: Old-style classes (not just instances) now support weak

2666
Victor Stinner66644262010-03-10 22:30:19 +00002667- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002668 (SIGINT). If an error occurs while importing the site module, the error is
2669 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002670 module.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002683- Issue #8310: Allow dis to examine new style classes.
2684
Georg Brandlfee0f442010-05-22 21:26:21 +00002685- Issue #8257: The Decimal construct now accepts a float instance directly,
2686 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002687
2688 >>> Decimal(1.1)
2689 Decimal('1.100000000000000088817841970012523233890533447265625')
2690
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002691- collections.Counter() now supports a subtract() method.
2692
Georg Brandlfee0f442010-05-22 21:26:21 +00002693- The functools module now has a total_ordering() class decorator to simplify
2694 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002695
Georg Brandlfee0f442010-05-22 21:26:21 +00002696- The functools module also adds cmp_to_key() as a tool to transition old-style
2697 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002698
Georg Brandlfee0f442010-05-22 21:26:21 +00002699- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2700 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002701
Georg Brandlfee0f442010-05-22 21:26:21 +00002702- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2703 InvalidOperation instead of returning False. (Comparisons involving a quiet
2704 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2705 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002706
Georg Brandlfee0f442010-05-22 21:26:21 +00002707- Issue #2531: Comparison operations between floats and Decimal instances now
2708 return a result based on the numeric values of the operands; previously they
2709 returned an arbitrary result based on the relative ordering of id(float) and
2710 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002711
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002712- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002713 argument `-` which tells it to read files to compile from stdin. Each line is
2714 read on demand and the named file is compiled immediately. (Original patch by
2715 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002716
Georg Brandlfee0f442010-05-22 21:26:21 +00002717- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002720- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2721 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002722 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002723
Georg Brandlfee0f442010-05-22 21:26:21 +00002724- Comparisons using one of <, <=, >, >= between a complex instance and a
2725 Fractions instance now raise TypeError instead of returning True/False. This
2726 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2727 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002728

2737
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002738- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002739 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2740 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002741
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002742- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002782- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002783 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2784 log file to compute the next rollover time. If the log file does not exist,
2785 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002786

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002826- Issue #8300: When passing a non-integer argument to struct.pack with any
2827 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002831- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2832 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2833 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002834 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2835 inconsistent: __int__ was used for some integer codes but not for others, and
2836 the set of integer codes for which it was used differed between native packing
2837 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003049- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
3050 now also used by regrtest to run all the tests in a temporary directory. The
3051 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent

3069 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003070 library would return a bogus result; on Solaris, it was possible to crash the

3085 and add the additional members returned in an OSVERSIONINFOEX structure. The
3086 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00003089- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3090 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3091 returning NULL. The macro now returns a statically allocated empty string
3092 instead.

3102 strings,
3103 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long

Antoine Pitroud840e512010-02-04 20:20:18 +00003137- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003138 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003144- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003145 file position when calling `truncate()`. It would previously change the file
3146 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003147 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3148
Georg Brandlba83f822010-03-14 09:50:54 +00003149- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3150 class used to represent files stored inside an archive. The new
3151 implementation is significantly faster and can be wrapped in a
3152 ``io.BufferedReader`` object for more speedups. It also solves an issue
3153 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3154 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003164- Issue #7748: Since unicode values are supported for some metadata options in
3165 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3166 encoded string for them. This ensures that the upload and register commands
3167 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003244- The ``__complex__()`` method is now looked up on the class of instances to
3245 make it consistent with other special methods.

3252 These functions and methods now raise TypeError instead. The majority of the
3253 effects of this change are in the extension modules, but some core functions
3254 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3255 and many unicode/str methods.

3271 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003420- Issue #3382: 'F' formatting for float and complex now convert the result to
3421 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3422 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003423
Georg Brandlba83f822010-03-14 09:50:54 +00003424- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3425 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003426
Georg Brandlba83f822010-03-14 09:50:54 +00003427- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3428 1e-100 used to raise OverflowError, but now gives the requested 120
3429 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003437
Georg Brandlba83f822010-03-14 09:50:54 +00003438- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3439 decimal string that's guaranteed to round back to x under correct rounding
3440 (with round-half-to-even rounding mode). Previously it gave a string based on
3441 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3442 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3443 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003444
Georg Brandlba83f822010-03-14 09:50:54 +00003445- Issue #7117: On almost all platforms: float-to-string and string-to-float
3446 conversions within Python are now correctly rounded. Places these conversions
3447 occur include: str for floats and complex numbers; the float and complex
3448 constructors; old-style and new-style numeric formatting; serialization and
3449 deserialization of floats and complex numbers using marshal, pickle and json;
3450 parsing of float and imaginary literals in Python code; Decimal-to-float
3451 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003452
Georg Brandlba83f822010-03-14 09:50:54 +00003453 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3454 providing correctly-rounded strtod and dtoa C functions. This code is
3455 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3456 the C compiler. There may be a small number of platforms on which correct
3457 operation of this code cannot be guaranteed, so the code is not used: notably,
3458 this applies to platforms where the C double format is not IEEE 754 binary64,
3459 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3460 and Python's configure script is unable to determine how to change the FPU
3461 precision. On these platforms conversions use the platform strtod and dtoa,
3462 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003463
Georg Brandlba83f822010-03-14 09:50:54 +00003464- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3465 uses the correctly-rounded string <-> float conversions described above (when
3466 available), and so produces correctly rounded results that will display nicely
3467 under the float repr. There are two related small changes: (1) round now
3468 accepts any class with an ``__index__()`` method for its second argument (but
3469 no longer accepts floats for the second argument), and (2) an excessively
3470 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3471 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003618- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3619 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3620 but with at least one decimal point and with a default precision
3621 of 12. Previously, the behavior the same but with a default precision of 6.
3622 This more closely matches ``str()``, and reduces surprises when adding
3623 alignment flags to the empty presentation type. This also affects the new
3624 complex.__format__ in the same way.
3625

3744
Georg Brandlba83f822010-03-14 09:50:54 +00003745- Issue #4935: The overflow checking code in the expandtabs() method common to
3746 str, bytes and bytearray could be optimized away by the compiler, letting the
3747 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00003748
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00003749- Issue #3720: Fix a crash when an iterator modifies its class and removes its

3755
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00003756- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
3757 collecting the oldest generation) so that allocating lots of objects without
3758 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00003759 Martin von Löwis at

3763
Georg Brandlba83f822010-03-14 09:50:54 +00003764- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3765 existing .py counterpart, override the co_filename attributes of all code
3766 objects if the original filename is obsolete (which can happen if the file has
3767 been renamed, moved, or if it is accessed through different paths). Patch by
3768 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00003769
Georg Brandlba83f822010-03-14 09:50:54 +00003770- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00003772- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
3773 file with `str' filename on Windows.
3774
Antoine Pitrouaa687902009-01-01 14:11:22 +00003775- Issue #3680: Reference cycles created through a dict, set or deque iterator
3776 did not get collected.
3777
Georg Brandlba83f822010-03-14 09:50:54 +00003778- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
3779 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00003780
Benjamin Peterson7af65562008-12-29 17:56:58 +00003781- Issue #4764: With io.open, IOError.filename is set when trying to open a
3782 directory on POSIX systems.
3783
Benjamin Petersonfe231b02008-12-29 17:47:42 +00003784- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
3785 systems.
3786
Georg Brandl6425a2f2008-12-28 11:54:53 +00003787- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003788 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003789
Skip Montanarof205c132008-12-23 03:30:15 +00003790- Added test case to ensure attempts to read from a file opened for writing
3791 fail.
3792
Georg Brandlba83f822010-03-14 09:50:54 +00003793- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3794 elapsed times, not only when some objects are uncollectable/unreachable.
3795 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00003796
Mark Dickinson1a707982008-12-17 16:14:37 +00003797- Issue #3439: Add a bit_length method to int and long.
3798
Georg Brandlba83f822010-03-14 09:50:54 +00003799- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original

Georg Brandlba83f822010-03-14 09:50:54 +00003802- Issue #4597: Fixed exception handling when the __exit__ function of a context
3803 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003804
Georg Brandlba83f822010-03-14 09:50:54 +00003805- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003806
Georg Brandlba83f822010-03-14 09:50:54 +00003807- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3808 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3809 instances. On a typical machine this saves 3 bytes of memory (on average) per
3810 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003811
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003812- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3813 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3814 instead of throwing a MemoryError.
3815
Georg Brandlba83f822010-03-14 09:50:54 +00003816- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3817 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003818
Benjamin Petersonc078f922008-11-21 22:27:24 +00003819- Issue #4367: Python would segfault during compiling when the unicodedata
3820 module couldn't be imported and \N escapes were present.
3821
Georg Brandlba83f822010-03-14 09:50:54 +00003822- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3823 file objects with closefd=False. The file descriptor is still kept open but
3824 the file object behaves like a closed file. The ``FileIO`` object also got a
3825 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003826
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003827- Issue #4348: Some bytearray methods returned that didn't cause any change to
3828 the bytearray, returned the same bytearray instead of a copy.
3829
Georg Brandlba83f822010-03-14 09:50:54 +00003830- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00003832- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3833
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003834- Issue #4048: The parser module now correctly validates relative imports.
3835
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003836- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3837 exec statement.
3838
Georg Brandlba83f822010-03-14 09:50:54 +00003839- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3840 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003841
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003842- Issue #4209: Enabling unicode_literals and the print_function in the same
3843 __future__ import didn't work.
3844
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003845- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003846 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003847
Georg Brandlba83f822010-03-14 09:50:54 +00003848- On windows, ``os.chdir()`` given unicode was not working if
3849 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3850 this code path is really executed because I cannot move to such directory on
3851 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003852
Georg Brandlba83f822010-03-14 09:50:54 +00003853- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3854 element is temporarily replaced with an equivalent frozenset. But the
3855 eventual KeyError would always report the empty ``frozenset()`` as the missing
3856 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003857
Georg Brandlba83f822010-03-14 09:50:54 +00003858- Issue #4509: Various issues surrounding resize of bytearray objects to which
3859 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00003860
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00003861- Issue #4748: Lambda generators no longer return a value.

3864
Gregory P. Smithae91d092009-03-02 05:13:57 +00003865- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
3866
Georg Brandlba83f822010-03-14 09:50:54 +00003867- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3868 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003869
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003870- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3871 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003872
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003873- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3874 returned them on 64bit platforms.
3875
Walter Dörwalded960ac2009-05-03 22:36:33 +00003876- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3877 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3878 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3879 of using the replace error handler in PyUnicode_DecodeUTF8().
3880
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003881- Issue #3739: The unicode-internal encoder now reports the number of characters
3882 consumed like any other encoder (instead of the number of bytes).
3883
Georg Brandlba83f822010-03-14 09:50:54 +00003884- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3885 allocator will be automatically disabled when running under Valgrind. This
3886 gives improved memory leak detection when running under Valgrind, while taking
3887 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00005110 leak-chasing test runs give sensible results. The previous method of reaping
5111 threads could return successfully while some Thread objects were still
5112 referenced. This also introduces a new private function: ``thread._count()``.

5119
R. David Murray14dcd432009-10-14 13:58:07 +00005120- Issue #7058: Added save/restore for things like sys.argv and cwd to

5122 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005129- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5130 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005131 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5132 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00005137- Issue #5354: New test support function import_fresh_module() makes it easy to
5138 import both normal and optimised versions of modules. test_heapq and
5139 test_warnings have been adjusted to use it, tests for other modules with both
5140 C and Python implementations in the stdlib can be adjusted to use it over
5141 time.

Georg Brandlba83f822010-03-14 09:50:54 +00005149- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5150 should cause a test to be skipped are now done using import_module from test
5151 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005252- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5253
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005254- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5255 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5256 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5257 ``printf`` function, whereas PyString_FromFormat has an independent
5258 implementation and uses "%zd" on all platforms for size_t values.
5259 This makes a difference on win64, where ``printf`` needs "%Id" to display
5260 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005262- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5266 object; previously an int would be returned for small values. the __long__
5267 method is allowed to return either an int or a long, but the behaviour of
5268 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005277 was correctly parsed but parsing of subsequent arguments failed.
5278
Vinay Sajip35e3b032008-09-01 14:33:59 +00005279- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005280 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5281 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5282 when given a tuple of classes as second argument, were looking up
5283 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5284 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005423What's New in Python 2.6 beta 3?
5424================================
5425
Barry Warsaw07a4a382008-08-21 01:15:08 +00005426*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005427
5428Core and Builtins
5429-----------------
5430
Guido van Rossumf8402962008-08-20 15:01:50 +00005431- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5432 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5433 extensions do not automatically benefit from the class attribute
5434 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5435 to their tp_flags field if they care. This is a backwards
5436 compatibility feature; in 3.0, all types will use the cache by
5437 default.
5438
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005439- Keyword arguments can now follow starred arguments. (``f(a, *args,
5440 keyword=23)`` is now valid syntax.)
5441
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005442- ctypes function pointers that are COM methods have a boolean True
5443 value again.
5444
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005445- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5446 by denying s# to parse objects that have a releasebuffer procedure,
5447 and introducing s*.
5448
Georg Brandl1e13ea92008-08-11 09:07:59 +00005449- Issue #3537: Fix an assertion failure when an empty but presized dict
5450 object was stored in the freelist.
5451
Mark Dickinsonb6467572008-08-04 21:30:09 +00005452- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5453 ValueError consistently across platforms.
5454
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005455- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5456 (64bit Unix, for example), unichr() would truncate its argument and return
5457 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5458
Neal Norwitze7d8be82008-07-31 17:17:14 +00005459- Apply security patches from Apple.
5460
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005461- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5462 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5463
Antoine Pitrou92f82162008-07-25 22:22:08 +00005464- Issue #1819: function calls with several named parameters are now on
5465 average 35% faster (as measured by pybench).
5466
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005467- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5468 the python debugger steps into a class statement: the free variables (local
5469 variables defined in an outer scope) would be deleted from the outer scope.
5470
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005471- Issue #2620: Overflow checking when allocating or reallocating memory
5472 was not always being done properly in some python types and extension
5473 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5474 all been updated to perform better checks and places in the code that
5475 would previously leak memory on the error path when such an allocation
5476 failed have been fixed.

5479-------
5480
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005481- Issue #3612: Added some missing basic types in ctypes.wintypes.
5482
Benjamin Petersone977ad42008-08-20 01:42:01 +00005483- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5484 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5485
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005486- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5487 version reported by these tools does not necessarily follow the python
5488 version numbering scheme, so the module is less strict when parsing it.
5489
Nick Coghlanf70385a2008-08-18 12:42:46 +00005490- Issue #2235: Added Py3k warnings for types which will become unhashable
5491 under the stricter __hash__ inheritance rules in 3.0. Several types
5492 which did not meet the rules for hash invariants and were already
5493 unhashable in 3.0 have now been explicitly flagged as unhashable in
5494 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5495 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5496
Brett Cannon88f801d2008-08-18 00:46:22 +00005497- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5498 imported into the module but exposed as part of the module's API.
5499
Brett Cannon7b96f072008-08-18 00:41:11 +00005500- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5501
Brett Cannon46225e72008-08-18 00:36:52 +00005502- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5503
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005504- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5505
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005506- Issue #3575: Incremental decoder's decode function now takes bytearray
5507 by using 's*' instead of 't#'.
5508
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005509- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005510 fails unicode conversion on 2nd parameter. (windows only)
5511
Georg Brandl222e2082010-08-01 22:27:39 +00005512- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005513 in a redirect.
5514
Brett Cannonabe423e2008-08-16 21:47:07 +00005515- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005516 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005517
Facundo Batistaeb90b782008-08-16 14:44:07 +00005518- Issue #2776: fixed small issue when handling an URL with double slash
5519 after a 302 response in the case of not going through a proxy.
5520
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005521- Issue #2676: in the email package, content-type parsing was hanging on
5522 pathological input because of quadratic or exponential behaviour of a
5523 regular expression.
5524
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005525- Issue #3476: binary buffered reading through the new "io" library is now
5526 thread-safe.
5527
Brett Cannonbf3157b2008-08-14 05:00:03 +00005528- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5529 since mimetools itself is deprecated. Because modules are cached, all
5530 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5531
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005532- Issue #3134: shutil referenced undefined WindowsError symbol.
5533
Robert Schuppenies14646332008-08-10 11:01:53 +00005534- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5535 menu entries were not deleted.
5536
Brett Cannon83e81842008-08-09 23:30:55 +00005537- Copied the implementation of reduce() to _functools.reduce() to have a
5538 version that did not raise a DeprecationWarning under -3.
5539
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005540- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5541 a MemoryError rather than silently stop the iteration.
5542
Guido van Rossum59ce9012008-08-09 14:55:34 +00005543- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5544 to _sre.compile() will now be rejected. This should not affect anybody
5545 since the re.compile() function never generates invalid re-bytecode.
5546
Skip Montanaroa032bf42008-08-08 22:52:51 +00005547- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5548 upon first access it can be automatically initialized from the csv file if
5549 it wasn't initialized during instantiation.
5550
Brett Cannon3aa2a492008-08-06 22:28:09 +00005551- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5552 the reload() built-in has been removed.
5553
Brett Cannon7e30b672008-08-04 21:52:25 +00005554- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005555 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5559 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5560 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005561
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005562- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5563 raised an AttributeError.
5564
Benjamin Peterson01a24322008-07-28 23:35:27 +00005565- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005566 asking for a specific length. This problem only affected files opened
5567 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005568
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005569- Issue #3449: Update decimal module to use most recent specification
5570 (v. 1.68) and tests (v. 2.58) from IBM.
5571
Georg Brandl222e2082010-08-01 22:27:39 +00005572- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005573

5576
Georg Brandlf9efabb2008-07-23 15:16:45 +00005577- Deprecate the "ast" parser function aliases.
5578
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005579- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5580
5581- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5582 invalid arguments.
5583
5584- Issue #3302: Fix several crashes when calling locale's gettext functions
5585 with None arguments.
5586
5587- Issue #3389: Allow resolving dotted names for handlers in logging
5588 configuration files.
5589
5590- Deprecate the sunaudio module for removal in Python 3.0.
5591
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005592- Issue #3394: zipfile.writestr sets external attributes when passed a
5593 file name rather than a ZipInfo instance, so files are extracted with
5594 mode 0600 rather than 000 under Unix.
5595
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005596- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5597 argument in python 2.5, this broke code that subclassed Popen to include its
5598 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5609 interaction with the tp_hash slot (added in 2.6b2) are now documented
5610
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005611- Issue #643841: The language reference now provides more detailed
5612 coverage of the lookup process for special methods. The disclaimers
5613 regarding lack of coverage of new-style classes have also been
5614 removed, since the coverage is now fairly reasonable.

5619
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005620*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005622Core and Builtins
5623-----------------
5624
Georg Brandl3e483f62008-07-16 22:57:41 +00005625- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5626 its methods now allow for items objects that can be converted to
5627 an integer using operator.index().
5628
Mark Dickinson64b7e502008-07-16 09:40:03 +00005629- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5630 produced a ValueError instead of giving the correct float.
5631
Eric Smitha5fa5a22008-07-16 00:11:49 +00005632- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5633 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5634
Mark Dickinson7103aa42008-07-15 19:08:33 +00005635- Issue #3008: the float type has a new instance method 'float.hex'
5636 and a new class method 'float.fromhex' to convert floating-point
5637 numbers to and from hexadecimal strings, respectively.
5638
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005639- Issue #2235: __hash__ is once again inherited by default. To allow
5640 collections.Hashable to remain meaningful in the presence of the
5641 default hash implementation (object.__hash__), it is now possible
5642 to explicit block inheritance of hash by setting __hash__=None at
5643 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5644 level.
5645
Nick Coghlanb028f502008-07-13 14:52:36 +00005646- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5647 the parent module cannot be found while performing an absolute import.
5648 This means that an incorrectly defined __package__ attribute will
5649 now only prevent relative imports in that module rather than causing
5650 all imports from that module to fail.
5651
Nick Coghlan14ff9942008-07-08 14:21:42 +00005652- Issue #2517: Allow unicode messages in Exceptions again by correctly
5653 bypassing the instance dictionary when looking up __unicode__ on
5654 new-style classes.
5655
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005656- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5657 set to a custom object whose write() method happens to install
5658 another file in sys.stdout.
5659
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005660- Issue #3088: Corrected a race condition in classes derived from

5662 another thread's dictionary.
5663
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005664- Issue #3004: Minor change to slice.indices(): the start and stop
5665 arguments are now treated identically, making the behaviour easier
5666 to describe and understand. For example, slice(None, -10,
5667 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5668 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5669 10, -1).
5670
Georg Brandl278fc502008-07-19 12:46:12 +00005671- Issue #3219: Calling a function with repeated keyword arguments,
5672 f(a=2, a=23), would not cause a syntax error. This was a regression
5673 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00006123 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006124
6125 This is controlled by the configure argument ``--with-universal-archs``:
6126
6127 - ``--with-universal-archs=all``: install 4-way universal
6128
6129 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6130
6131 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6132
6133 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006185- Issue #1631171: Re-implement the 'warnings' module in C (the
6186 original Python code has been kept as backup). This will allow for
6187 using the 'warning's machinery in such places as the parser where
6188 use of pure Python code is not possible. Both the ``showarning()``
6189 and ``formatwarning()`` gain an optional 'line' argument which is
6190 not called by default for backwards-compatibility reasons. Setting
6191 ``warnings.showwarning()`` to an implementation that lacks support
6192 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006255- Issue #2550: The approach used by client/server code for obtaining
6256 ports to listen on in network-oriented tests has been refined in an
6257 effort to facilitate running multiple instances of the entire
6258 regression test suite in parallel without issue.
6259 test_support.bind_port() has been fixed such that it will always
6260 return a unique port -- which wasn't always the case with the
6261 previous implementation, especially if socket options had been set
6262 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6263 new implementation of bind_port() will actually raise an exception
6264 if it is passed an AF_INET/SOCK_STREAM socket with either the
6265 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6266 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6267 the socket it's been passed. This currently only applies to
6268 Windows. This option prevents any other sockets from binding to the
6269 host/port we've bound to, thus removing the possibility of the
6270 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6271 when a second SOCK_STREAM socket binds and accepts to a host/port
6272 that's already been bound by another socket. The optional preferred
6273 port parameter to bind_port() has been removed. Under no
6274 circumstances should tests be hard coding ports!
6275
6276 test_support.find_unused_port() has also been introduced, which will
6277 pass a temporary socket object to bind_port() in order to obtain an
6278 unused port. The temporary socket object is then closed and
6279 deleted, and the port is returned. This method should only be used
6280 for obtaining an unused port in order to pass to an external program
6281 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6282 a parameter to a server-oriented class that doesn't give you direct
6283 access to the underlying socket used.
6284
6285 Finally, test_support.HOST has been introduced, which should be used
6286 for the host argument of any relevant socket calls (i.e. bind and
6287 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006288
6289 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006290 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006291 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6292 test_asynchat and test_socket_ssl.
6293
Georg Brandl3ee81df2008-05-17 18:14:43 +00006294 It is now possible for multiple instances of the regression test
6295 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00006499- The bundled libffi copy is now in sync with the recently released
6500 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006501 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
6502 files are used. On all linux systems the --with-system-ffi
6503 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00006564- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006565 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00006574- Added the future_builtins module, which contains hex() and oct().
6575 These are the PEP 3127 version of these functions, designed to be
6576 compatible with the hex() and oct() builtins from Python 3.0. They
6577 differ slightly in their output formats from the existing, unchanged
6578 Python 2.6 builtins. The expected usage of the future_builtins
6579 module is:
6580 from future_builtins import hex, oct
6581
Eric Smith7ef40bf2008-02-20 23:34:22 +00006582- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6583 exponents for exponents with absolute value < 100. Follows C99
6584 standard. This is a change on Windows, which would use 3 digits.
6585 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6586 so that any alterations it does to the resulting string will be
6587 available in stringlib/formatter.h (for float.__format__).
6588
Eric Smith5a3c1352008-02-19 13:21:56 +00006589- Implemented PEP 3101, Advanced String Formatting. This adds a new
6590 builtin format(); a format() method for str and unicode; a
6591 __format__() method to object, str, unicode, int, long, float, and
6592 datetime; the class string.Formatter; and the C API
6593 PyObject_Format().
6594
Georg Brandl3ee81df2008-05-17 18:14:43 +00006595- Fixed several potential crashes, all caused by specially crafted
6596 __del__ methods exploiting objects in temporarily inconsistent
6597 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006598
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006599- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006600 prevent a possible crash: an Abstract Base Class would try to access
6601 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006602

Georg Brandl3ee81df2008-05-17 18:14:43 +00006606- Clear all free lists during a gc.collect() of the highest generation
6607 in order to allow pymalloc to free more arenas. Python may give back
6608 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006609
Georg Brandl3ee81df2008-05-17 18:14:43 +00006610- Issue #2045: Fix an infinite recursion triggered when printing a
6611 subclass of collections.defaultdict, if its default_factory is set
6612 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006613
Christian Heimesf75dbef2008-02-08 00:11:31 +00006614- Fixed a minor memory leak in dictobject.c. The content of the free
6615 list was not freed on interpreter shutdown.
6616
Georg Brandl21e99f42010-03-07 15:23:59 +00006617- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006618 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006619
Georg Brandl3ee81df2008-05-17 18:14:43 +00006620- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6621 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006622 to compact the internal free lists of pre-allocted ints and floats.
6623
Georg Brandl3ee81df2008-05-17 18:14:43 +00006624- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6625 calls. Python expected the return type int but the fork familie
6626 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006627
Georg Brandl3ee81df2008-05-17 18:14:43 +00006628- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6629 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006640- Patch #1473257: generator objects gain a gi_code attribute. This is
6641 the same object as the func_code attribute of the function that
6642 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006643
Georg Brandl3ee81df2008-05-17 18:14:43 +00006644- Issue #1920: "while 0" statements were completely removed by the
6645 compiler, even in the presence of an "else" clause, which is
6646 supposed to be run when the condition is false. Now the compiler
6647 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006648
Guido van Rossumeead05f2008-01-24 18:21:02 +00006649- A few crashers fixed: weakref_in_del.py (issue #1377858);
6650 loosing_dict_ref.py (issue #1303614, test67.py);
6651 borrowed_ref_[34].py (not in tracker).
6652
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006653- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006654 suppressed while an extension is loaded by calling SetErrorMode in

6656
Georg Brandl3ee81df2008-05-17 18:14:43 +00006657- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006658 several extension methods and modules do not work without unicode
6659 support.
6660
Georg Brandl26543b12008-01-21 18:36:51 +00006661- Issue #1882: when compiling code from a string, encoding cookies in the
6662 second line of code were not always recognized correctly.
6663
Georg Brandl14404b62008-01-19 19:27:05 +00006664- Issue #1679: "0x" was taken as a valid integer literal.
6665
Georg Brandl6caad7d2008-01-26 14:19:22 +00006666- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006667 added.
6668
Christian Heimesc94e2b52008-01-14 04:13:37 +00006669- sys.float_info / PyFloat_GetInfo: The floating point information
6670 object was converted from a dict to a specialized structseq object.
6671
Georg Brandl3ee81df2008-05-17 18:14:43 +00006672- Patch #1816: Added sys.flags structseq. It exposes the status of
6673 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006674
Georg Brandl3ee81df2008-05-17 18:14:43 +00006675- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00006701 and INF. float("nan"), float("inf") and float("-inf") now work on
6702 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006703
Georg Brandl3ee81df2008-05-17 18:14:43 +00006704- Compiler now generates simpler and faster code for dictionary
6705 literals. The oparg for BUILD_MAP now indicates an estimated
6706 dictionary size. There is a new opcode, STORE_MAP, for adding
6707 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006736- Patch #1739468: Directories and zipfiles containing a __main__.py
6737 file can now be directly executed by passing their name to the
6738 interpreter. The directory/zipfile is automatically inserted as the
6739 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006741- Issue #1265: Fix a problem with sys.settrace, if the tracing
6742 function uses a generator expression when at the same time the
6743 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006744
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006745- sets and frozensets now have an isdisjoint() method.
6746

6748
Neal Norwitz44f326e2007-10-05 05:29:17 +00006749- Fix warnings found by the new version of the Coverity checker.
6750
Georg Brandl21e99f42010-03-07 15:23:59 +00006751- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006752 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6753 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006754
Georg Brandl3ee81df2008-05-17 18:14:43 +00006755- Issue #1686386: Tuple's tp_repr did not take into account the
6756 possibility of having a self-referential tuple, which is possible
6757 from C code. Nor did object's tp_str consider that a type's tp_str
6758 could do something that could lead to an inifinite recursion.
6759 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6760 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006761
Georg Brandl3ee81df2008-05-17 18:14:43 +00006762- Issue #1164: It was possible to trigger deadlock when using the
6763 'print' statement to write to a file since the GIL was not released
6764 as needed. Now PyObject_Print() does the right thing along with
6765 various tp_print implementations of the built-in types and those in
6766 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006767
Georg Brandl3ee81df2008-05-17 18:14:43 +00006768- Issue #1147: Exceptions were directly allowing string exceptions in
6769 their throw() method even though string exceptions no longer
6770 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006771
Georg Brandl3ee81df2008-05-17 18:14:43 +00006772- Issue #1096: Prevent a segfault from getting the repr of a very
6773 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006774
Brett Cannon1e534b52007-09-07 04:18:30 +00006775- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006776 PyObject_Call() never calling back out to Python code to trigger
6777 recursion depth updates/checks. Required the creation of a static
6778 RuntimeError instance in case normalizing an exception put the
6779 recursion check value past its limit. Fixes crashers
6780 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006781
Georg Brandl3ee81df2008-05-17 18:14:43 +00006782- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006795- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006796 __*__ attributes. (Some already existed, e.g., __doc__ and
6797 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006798
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006799- Add -3 option to the interpreter to warn about features that are
6800 deprecated and will be changed/removed in Python 3.0.
6801
Georg Brandl2134e752007-05-21 20:34:16 +00006802- Patch #1686487: you can now pass any mapping after '**' in function
6803 calls.
6804
Collin Winter62903052007-05-18 23:11:24 +00006805- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006806 "except E as target:". This is to provide forwards compatibility
6807 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006808
Brett Cannon229cee22007-05-05 01:34:02 +00006809- Deprecate BaseException.message as per PEP 352.
6810
Georg Brandl3ee81df2008-05-17 18:14:43 +00006811- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006812 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006813
Vinay Sajip8549ce32007-05-06 17:53:37 +00006814- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006815 setting a plain string, ie don't expand to single letter identifiers.
6816
Raymond Hettinger13936692007-04-11 18:40:58 +00006817- Request #1191699: Slices can now be pickled.
6818
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006819- Request #1193128: str.translate() now allows a None argument for
6820 translations that only remove characters without re-mapping the
6821 remaining characters.
6822
Georg Brandl5cb76c12007-03-21 09:00:39 +00006823- Patch #1682205: a TypeError while unpacking an iterable is no longer
6824 masked by a generic one with the message "unpack non-sequence".
6825
Neal Norwitzaa754b72007-03-21 06:39:48 +00006826- Remove unused file Python/fmod.c.
6827
Guido van Rossum143b5642007-03-23 04:58:42 +00006828- Bug #1683368: The object.__init__() and object.__new__() methods are
6829 now stricter in rejecting excess arguments. The only time when
6830 either allows excess arguments is when it is not overridden and the
6831 other one is. For backwards compatibility, when both are
6832 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006833 warning later). Also, type.__init__() insists on the same signature
6834 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006835
Georg Brandl3ee81df2008-05-17 18:14:43 +00006836- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6837 object to complex using its __complex__() method before falling back
6838 to the __float__() method. Therefore, the functions in the cmath
6839 module now can operate on objects that define a __complex__()
6840 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006841
Georg Brandl3ee81df2008-05-17 18:14:43 +00006842- Patch #1623563: allow __class__ assignment for classes with
6843 __slots__. The old and the new class are still required to have the
6844 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006845

6850 ``object.__reduce_ex__()`` is called with an object that is faking
6851 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006852
Georg Brandl3ee81df2008-05-17 18:14:43 +00006853- Patch #1680015: Don't modify __slots__ tuple if it contains an

6857
Georg Brandl7b9c5552007-03-12 14:30:05 +00006858- Bug #1678647: write a newline after printing an exception in any
6859 case, even when converting the value to a string failed.
6860
Georg Brandl871f1bc2007-03-12 13:17:36 +00006861- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006862 its argument, if it exists. If not, it will work like before. This
6863 allows customizing the output of dir() in the presence of a
6864 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006865
Collin Winter276887b2007-03-12 16:11:39 +00006866- Patch #922167: Python no longer segfaults when faced with infinitely
6867 self-recursive reload() calls (as reported by bug #742342).
6868

Georg Brandl3ee81df2008-05-17 18:14:43 +00006872- Patch #1491866: change the complex() constructor to allow
6873 parthensized forms. This means complex(repr(x)) now works instead of
6874 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006875
Georg Brandlaa2321b2007-03-07 00:40:28 +00006876- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006877 makes the filenames the warning module prints much more sensible
6878 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006879
Georg Brandl49aafc92007-03-07 00:34:46 +00006880- Variant of patch #697613: don't exit the interpreter on a SystemExit
6881 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006882 variable is given, but break into the interactive interpreter just
6883 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00006890
Georg Brandl0fca97a2007-03-05 22:28:08 +00006891- Patch #1674228: when assigning a slice (old-style), check for the
6892 sq_ass_slice instead of the sq_slice slot.
6893
Georg Brandl3ee81df2008-05-17 18:14:43 +00006894- When printing an unraisable error, don't print exceptions. before
6895 the name. This duplicates the behavior whening normally printing
6896 exceptions.

7524 -- the failure just occurred later, with a more cumbersome
7525 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007806- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7807 with RFC 3207 and forgets any knowledge obtained from the server not
7808 obtained from the TLS negotiation itself. Patch contributed by Bill
7809 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007810
Georg Brandl3ee81df2008-05-17 18:14:43 +00007811- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007812 that the SMTP.starttls() caller no longer needs to call ehlo()
7813 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007814 does not claim to support starttls. Adds the
7815 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7896 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7897 silently miscode subclasses of those types. Now, it raises a
7898 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007899

Georg Brandl3ee81df2008-05-17 18:14:43 +00007914 time so that opening a database previously created with the DB_DUP
7915 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7916 opens. Specifically: dictionary assignment to a DB object will
7917 replace all values for a given key when the database allows
7918 duplicate values. DB users should use DB.put(k, v) when they want
7919 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007920

7926 characters with ASCII value less than 32. Also, it correctly quotes
7927 dots only if they occur on a single line, as opposed to the previous
7928 behavior of quoting dots if they are the second character of any
7929 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007930

8252-----
8253
Georg Brandl3ee81df2008-05-17 18:14:43 +00008254- Unified naming convention for free lists and their limits. All free
8255 lists in Object/ are named ``free_list``, the counter ``numfree``
8256 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8257 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008258
Georg Brandl3ee81df2008-05-17 18:14:43 +00008259- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8260 to ``PyTuple_SetItem``, it can be used to populate a brand new
8261 frozenset; but it does not steal a reference to the added item.

8273
Georg Brandl3ee81df2008-05-17 18:14:43 +00008274- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8275 of w# format code incorrectly truncated the length to an int, even
8276 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8277 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008278
Georg Brandl3ee81df2008-05-17 18:14:43 +00008279- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8296
8297- Fix some leftovers from the conversion from int to Py_ssize_t
8298 (relevant to strings and sequences of more than 2**31 items).
8299
8300- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8301 outside of pystate.c and should not be necessary.
8302
Georg Brandl3ee81df2008-05-17 18:14:43 +00008303- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8304 absolute imports. In earlier versions they might have used relative
8305 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008306
Georg Brandl3ee81df2008-05-17 18:14:43 +00008307- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8308 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008309
Georg Brandl3ee81df2008-05-17 18:14:43 +00008310- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008317- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8318 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8319 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8320 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008321

Georg Brandl3ee81df2008-05-17 18:14:43 +00008335- Removed the macfs module. It had been deprecated since Python 2.5.
8336 This lead to the deprecation of macostools.touched() as it relied
8337 solely on macfs and was a no-op under OS X.
