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

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

Ned Deily0d0ea482012-02-10 12:59:06 +0100779- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
780 Distutils-based packages with C extension modules may fail because
781 Apple has removed gcc-4.2, the version used to build python.org
782 64-bit/32-bit Pythons. If the user does not explicitly override
783 the default C compiler by setting the CC environment variable,
784 Distutils will now attempt to compile extension modules with clang
785 if gcc-4.2 is required but not found. Also as a convenience, if
786 the user does explicitly set CC, substitute its value as the default
787 compiler in the Distutils LDSHARED configuration variable for OS X.
788 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
789 SDK, neither of which are available in Xcode 4. This change does not
790 attempt to override settings to support their use with Xcode 4.)

1062
Ned Deily87e82bb2011-06-28 19:52:59 -07001063- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1064 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1065 interpreter process. This could cause failures in non-Distutils subprocesses
1066 and was unreliable since tests or user programs could modify the interpreter
1067 environment after Distutils set it. Instead, have Distutils set the the
1068 deployment target only in the environment of each build subprocess. It is
1069 still possible to globally override the default by setting
1070 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1071 greater or equal to the default value, the value with which the interpreter
1072 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04001100- sys.setcheckinterval() now updates the current ticker count as well as
1101 updating the check interval, so if the user decreases the check interval,
1102 the ticker doesn't have to wind down to zero from the old starting point
1103 before the new interval takes effect. And if the user increases the
1104 interval, it makes sure the new limit takes effect right away rather have an
1105 early task switch before recognizing the new interval.

2036
Antoine Pitrou2c7d6852010-09-23 19:55:24 +00002037- Issue #9928: Properly initialize the types exported by the bz2 module.
2038
Antoine Pitrou6391b342010-09-14 18:48:19 +00002039- Issue #9854: The default read() implementation in io.RawIOBase now
2040 handles non-blocking readinto() returning None correctly.
2041
Antoine Pitrouf7f390a2010-09-14 14:37:18 +00002042- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
2043 SSLSocket.sendto() to match the corresponding socket methods. Also,
2044 fix various SSLSocket methods to raise socket.error rather than an
2045 unhelpful TypeError when called on an unconnected socket. Original patch
2046 by Andrew Bennetts.
2047
Raymond Hettinger74f869e2010-09-13 22:14:36 +00002048- Issue #9826: OrderedDict.__repr__ can now handle self-referential

2055
Raymond Hettinger20397532010-09-12 02:11:45 +00002056- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2057 This prevents user-created self-referencing ordered dictionaries from
2058 becoming permanently uncollectable GC garbage. The downside is that
2059 removing __del__ means that the internal doubly-linked list has to wait for
2060 GC collection rather than freeing memory immediately when the refcnt drops
2061 to zero.
2062
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002063- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

2066
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002067- Issue #9792: In case of connection failure, socket.create_connection()
2068 would swallow the exception and raise a new one, making it impossible
2069 to fetch the original errno, or to filter timeout errors. Now the
2070 original error is re-raised.
2071
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002072- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

2074 be updated back after the system call. Original patch by Brian Brazil.

2080 ConfigParser.write.
2081
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002082- Issue #808164: Fixed socket.close to avoid references to globals, to

2091
R. David Murray7c4bf552010-08-25 01:45:57 +00002092- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2093 character years even if the message contains RFC822 two character years.
2094
Daniel Stutzbach91287322010-08-24 21:09:30 +00002095- Issue #8750: Fixed MutableSet's methods to correctly handle

2107 module now correctly return a set. (Patch by Eli Bendersky.)
2108
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002109- Issue #9617: Signals received during a low-level write operation aren't
2110 ignored by the buffered IO layer anymore.
2111
Benjamin Peterson52c36052010-08-21 03:03:22 +00002112- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2114
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002115- Issue #9626: the view methods for collections.OrderedDict() were returning

Antoine Pitroue1436d12010-08-12 15:25:51 +00002123- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2124 and a BadZipfile error is raised if it doesn't match (as used to be the

2126
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002127- Issue #9550: a BufferedReader could issue an additional read when the
2128 original read request had been satisfied, which could block indefinitely
2129 when the underlying raw IO channel was e.g. a socket. Report and original
2130 patch by Jason V. Miller.
2131
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002132- Issue #9551: Don't raise TypeError when setting the value to None for

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002520- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

2523 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2524 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

Georg Brandlfee0f442010-05-22 21:26:21 +00002880- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002881 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2882 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2883 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Petersonfbac6c12010-04-10 16:22:05 +00002901*Release date: 2010-04-10*
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00002902
2903Core and Builtins
2904-----------------
2905
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002906- Issue #7301: Add environment variable $PYTHONWARNINGS.
2907
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002908- Issue #8329: Don't return the same lists from select.select when no fds are
2909 changed.
2910
Georg Brandlfee0f442010-05-22 21:26:21 +00002911- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002912 on 64-bit machines. The shift count for either left or right shift is
2913 permitted to be up to sys.maxsize.
2914
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002915- Ensure that tokenization of identifiers is not affected by locale.
2916
Georg Brandlfee0f442010-05-22 21:26:21 +00002917- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002918
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002919- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2920
Georg Brandlfee0f442010-05-22 21:26:21 +00002921- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2922 with a non-empty format string. This is an effort to future-proof user
2923 code. If a derived class does not currently implement __format__ but later
2924 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002925 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002926 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002927
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002928- Issue #8268: Old-style classes (not just instances) now support weak

2932 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002933

Benjamin Peterson96545892010-03-21 20:21:00 +00002936- Issue #6474: Make error message from passing an inadequate number of keyword
2937 arguments to a function correct.
2938
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002939- Issue #8164: Don't allow lambda functions to have a docstring.
2940
Victor Stinner66644262010-03-10 22:30:19 +00002941- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002942 (SIGINT). If an error occurs while importing the site module, the error is
2943 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002944 module.

2955 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002956
Benjamin Peterson76a23c12010-04-04 23:23:22 +00002957- Issue #8310: Allow dis to examine new style classes.
2958
Georg Brandlfee0f442010-05-22 21:26:21 +00002959- Issue #8257: The Decimal construct now accepts a float instance directly,
2960 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002961
2962 >>> Decimal(1.1)
2963 Decimal('1.100000000000000088817841970012523233890533447265625')
2964
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002965- collections.Counter() now supports a subtract() method.
2966
Georg Brandlfee0f442010-05-22 21:26:21 +00002967- The functools module now has a total_ordering() class decorator to simplify
2968 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002969
Georg Brandlfee0f442010-05-22 21:26:21 +00002970- The functools module also adds cmp_to_key() as a tool to transition old-style
2971 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002972
Georg Brandlfee0f442010-05-22 21:26:21 +00002973- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2974 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002975
Georg Brandlfee0f442010-05-22 21:26:21 +00002976- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2977 InvalidOperation instead of returning False. (Comparisons involving a quiet
2978 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2979 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002980
Georg Brandlfee0f442010-05-22 21:26:21 +00002981- Issue #2531: Comparison operations between floats and Decimal instances now
2982 return a result based on the numeric values of the operands; previously they
2983 returned an arbitrary result based on the relative ordering of id(float) and
2984 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002985
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002986- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002987 argument `-` which tells it to read files to compile from stdin. Each line is
2988 read on demand and the named file is compiled immediately. (Original patch by
2989 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002990
Georg Brandlfee0f442010-05-22 21:26:21 +00002991- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2992 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002994- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2995 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002996 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002997
Georg Brandlfee0f442010-05-22 21:26:21 +00002998- Comparisons using one of <, <=, >, >= between a complex instance and a
2999 Fractions instance now raise TypeError instead of returning True/False. This
3000 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3001 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003002
Michael Foorde6410c52010-03-29 20:04:23 +00003003- Addition of ``WeakSet`` to the ``weakref`` module.

3011
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003012- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003013 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3014 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003015
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003016- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3017 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00003057 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3058 log file to compute the next rollover time. If the log file does not exist,
3059 the current time is used as the basis for the computation.

3101 integer format code, struct.pack first attempts to convert the non-integer

3106 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3107 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003108 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3109 inconsistent: __int__ was used for some integer codes but not for others, and
3110 the set of integer codes for which it was used differed between native packing
3111 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003323- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
3324 now also used by regrtest to run all the tests in a temporary directory. The
3325 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
3326 Xicluna who helped with the patch.

3343 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003344 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00003363- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3364 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3365 returning NULL. The macro now returns a statically allocated empty string
3366 instead.

3376 strings,
3377 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3378 numeric strings corresponding to subnormal values,
3379 (3) a memory leak for some values large enough to cause overflow, and
3380 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00003412 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003418- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003419 file position when calling `truncate()`. It would previously change the file
3420 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003421 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3422
Georg Brandlba83f822010-03-14 09:50:54 +00003423- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3424 class used to represent files stored inside an archive. The new
3425 implementation is significantly faster and can be wrapped in a
3426 ``io.BufferedReader`` object for more speedups. It also solves an issue
3427 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3428 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003438- Issue #7748: Since unicode values are supported for some metadata options in
3439 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3440 encoded string for them. This ensures that the upload and register commands
3441 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003518- The ``__complex__()`` method is now looked up on the class of instances to
3519 make it consistent with other special methods.

3523
Mark Dickinson1b34d252010-01-01 17:27:30 +00003524- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003525 DeprecationWarning when passed a float argument where an integer was expected.
3526 These functions and methods now raise TypeError instead. The majority of the
3527 effects of this change are in the extension modules, but some core functions
3528 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3529 and many unicode/str methods.

3543 of integers: the result of a/b is now correctly rounded for ints a and b (at
3544 least on IEEE 754 platforms), and in particular does not depend on the
3545 internal representation of a long.

3553
Georg Brandlba83f822010-03-14 09:50:54 +00003554 These executables now work properly with the arch(1) command: ``arch -ppc
3555 python`` will start a universal binary version of python in PPC mode (unlike
3556 previous releases).

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003711
Georg Brandlba83f822010-03-14 09:50:54 +00003712- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3713 decimal string that's guaranteed to round back to x under correct rounding
3714 (with round-half-to-even rounding mode). Previously it gave a string based on
3715 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3716 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3717 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003718
Georg Brandlba83f822010-03-14 09:50:54 +00003719- Issue #7117: On almost all platforms: float-to-string and string-to-float
3720 conversions within Python are now correctly rounded. Places these conversions
3721 occur include: str for floats and complex numbers; the float and complex
3722 constructors; old-style and new-style numeric formatting; serialization and
3723 deserialization of floats and complex numbers using marshal, pickle and json;
3724 parsing of float and imaginary literals in Python code; Decimal-to-float
3725 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003726
Georg Brandlba83f822010-03-14 09:50:54 +00003727 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3728 providing correctly-rounded strtod and dtoa C functions. This code is
3729 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3730 the C compiler. There may be a small number of platforms on which correct
3731 operation of this code cannot be guaranteed, so the code is not used: notably,
3732 this applies to platforms where the C double format is not IEEE 754 binary64,
3733 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3734 and Python's configure script is unable to determine how to change the FPU
3735 precision. On these platforms conversions use the platform strtod and dtoa,
3736 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003737
Georg Brandlba83f822010-03-14 09:50:54 +00003738- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3739 uses the correctly-rounded string <-> float conversions described above (when
3740 available), and so produces correctly rounded results that will display nicely
3741 under the float repr. There are two related small changes: (1) round now
3742 accepts any class with an ``__index__()`` method for its second argument (but
3743 no longer accepts floats for the second argument), and (2) an excessively
3744 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3745 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003892- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3893 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3894 but with at least one decimal point and with a default precision
3895 of 12. Previously, the behavior the same but with a default precision of 6.
3896 This more closely matches ``str()``, and reduces surprises when adding
3897 alignment flags to the empty presentation type. This also affects the new
3898 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00004038- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4039 existing .py counterpart, override the co_filename attributes of all code

4095
Georg Brandlba83f822010-03-14 09:50:54 +00004096- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4097 file objects with closefd=False. The file descriptor is still kept open but
4098 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00004122- On windows, ``os.chdir()`` given unicode was not working if

4124 this code path is really executed because I cannot move to such directory on
4125 win2k)

Walter Dörwalded960ac2009-05-03 22:36:33 +00004150- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4151 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4152 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4153 of using the replace error handler in PyUnicode_DecodeUTF8().
4154
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004155- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00004158- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

4160 gives improved memory leak detection when running under Valgrind, while taking
4161 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00005384 leak-chasing test runs give sensible results. The previous method of reaping
5385 threads could return successfully while some Thread objects were still
5386 referenced. This also introduces a new private function: ``thread._count()``.

5404 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005405 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5406 the tests if DISPLAY is defined but can't be used.

5412 import both normal and optimised versions of modules. test_heapq and

5527
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005528- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5529 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5530 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5531 ``printf`` function, whereas PyString_FromFormat has an independent
5532 implementation and uses "%zd" on all platforms for size_t values.
5533 This makes a difference on win64, where ``printf`` needs "%Id" to display
5534 64bit values.

5540 object; previously an int would be returned for small values. the __long__
5541 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005551 was correctly parsed but parsing of subsequent arguments failed.
5552
Vinay Sajip35e3b032008-09-01 14:33:59 +00005553- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005554 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5555 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5556 when given a tuple of classes as second argument, were looking up
5557 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5558 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005697What's New in Python 2.6 beta 3?
5698================================
5699
Barry Warsaw07a4a382008-08-21 01:15:08 +00005700*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005701
5702Core and Builtins
5703-----------------
5704
Guido van Rossumf8402962008-08-20 15:01:50 +00005705- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5706 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5707 extensions do not automatically benefit from the class attribute
5708 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5709 to their tp_flags field if they care. This is a backwards
5710 compatibility feature; in 3.0, all types will use the cache by
5711 default.
5712
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005713- Keyword arguments can now follow starred arguments. (``f(a, *args,
5714 keyword=23)`` is now valid syntax.)
5715
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005716- ctypes function pointers that are COM methods have a boolean True
5717 value again.
5718
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005719- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5720 by denying s# to parse objects that have a releasebuffer procedure,
5721 and introducing s*.
5722
Georg Brandl1e13ea92008-08-11 09:07:59 +00005723- Issue #3537: Fix an assertion failure when an empty but presized dict
5724 object was stored in the freelist.
5725
Mark Dickinsonb6467572008-08-04 21:30:09 +00005726- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5727 ValueError consistently across platforms.
5728
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005729- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5730 (64bit Unix, for example), unichr() would truncate its argument and return
5731 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5732
Neal Norwitze7d8be82008-07-31 17:17:14 +00005733- Apply security patches from Apple.
5734
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005735- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5736 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5737
Antoine Pitrou92f82162008-07-25 22:22:08 +00005738- Issue #1819: function calls with several named parameters are now on
5739 average 35% faster (as measured by pybench).
5740
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005741- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5742 the python debugger steps into a class statement: the free variables (local
5743 variables defined in an outer scope) would be deleted from the outer scope.
5744
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005745- Issue #2620: Overflow checking when allocating or reallocating memory
5746 was not always being done properly in some python types and extension
5747 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5748 all been updated to perform better checks and places in the code that
5749 would previously leak memory on the error path when such an allocation
5750 failed have been fixed.
5751

5753-------
5754
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005755- Issue #3612: Added some missing basic types in ctypes.wintypes.
5756
Benjamin Petersone977ad42008-08-20 01:42:01 +00005757- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5758 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5759
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005760- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5761 version reported by these tools does not necessarily follow the python
5762 version numbering scheme, so the module is less strict when parsing it.
5763
Nick Coghlanf70385a2008-08-18 12:42:46 +00005764- Issue #2235: Added Py3k warnings for types which will become unhashable
5765 under the stricter __hash__ inheritance rules in 3.0. Several types
5766 which did not meet the rules for hash invariants and were already
5767 unhashable in 3.0 have now been explicitly flagged as unhashable in
5768 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5769 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5770
Brett Cannon88f801d2008-08-18 00:46:22 +00005771- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5772 imported into the module but exposed as part of the module's API.
5773
Brett Cannon7b96f072008-08-18 00:41:11 +00005774- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5775
Brett Cannon46225e72008-08-18 00:36:52 +00005776- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5777
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005778- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5779
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005780- Issue #3575: Incremental decoder's decode function now takes bytearray
5781 by using 's*' instead of 't#'.
5782
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005783- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005784 fails unicode conversion on 2nd parameter. (windows only)
5785
Georg Brandl222e2082010-08-01 22:27:39 +00005786- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005787 in a redirect.
5788
Brett Cannonabe423e2008-08-16 21:47:07 +00005789- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005790 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005791
Facundo Batistaeb90b782008-08-16 14:44:07 +00005792- Issue #2776: fixed small issue when handling an URL with double slash
5793 after a 302 response in the case of not going through a proxy.
5794
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005795- Issue #2676: in the email package, content-type parsing was hanging on
5796 pathological input because of quadratic or exponential behaviour of a
5797 regular expression.
5798
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005799- Issue #3476: binary buffered reading through the new "io" library is now
5800 thread-safe.
5801
Brett Cannonbf3157b2008-08-14 05:00:03 +00005802- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5803 since mimetools itself is deprecated. Because modules are cached, all
5804 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5805
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005806- Issue #3134: shutil referenced undefined WindowsError symbol.
5807
Robert Schuppenies14646332008-08-10 11:01:53 +00005808- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5809 menu entries were not deleted.
5810
Brett Cannon83e81842008-08-09 23:30:55 +00005811- Copied the implementation of reduce() to _functools.reduce() to have a
5812 version that did not raise a DeprecationWarning under -3.
5813
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005814- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5815 a MemoryError rather than silently stop the iteration.
5816
Guido van Rossum59ce9012008-08-09 14:55:34 +00005817- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5818 to _sre.compile() will now be rejected. This should not affect anybody
5819 since the re.compile() function never generates invalid re-bytecode.
5820
Skip Montanaroa032bf42008-08-08 22:52:51 +00005821- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5822 upon first access it can be automatically initialized from the csv file if
5823 it wasn't initialized during instantiation.
5824
Brett Cannon3aa2a492008-08-06 22:28:09 +00005825- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5826 the reload() built-in has been removed.
5827
Brett Cannon7e30b672008-08-04 21:52:25 +00005828- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005829 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5832 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5833 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5834 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005835
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005836- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5837 raised an AttributeError.
5838
Benjamin Peterson01a24322008-07-28 23:35:27 +00005839- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005840 asking for a specific length. This problem only affected files opened
5841 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005842
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005843- Issue #3449: Update decimal module to use most recent specification
5844 (v. 1.68) and tests (v. 2.58) from IBM.
5845
Georg Brandl222e2082010-08-01 22:27:39 +00005846- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005847
Georg Brandl222e2082010-08-01 22:27:39 +00005848- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00005849 on a closed shelf.
5850
Georg Brandlf9efabb2008-07-23 15:16:45 +00005851- Deprecate the "ast" parser function aliases.
5852
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005853- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5854
5855- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5856 invalid arguments.
5857
5858- Issue #3302: Fix several crashes when calling locale's gettext functions
5859 with None arguments.
5860
5861- Issue #3389: Allow resolving dotted names for handlers in logging
5862 configuration files.
5863
5864- Deprecate the sunaudio module for removal in Python 3.0.
5865
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005866- Issue #3394: zipfile.writestr sets external attributes when passed a
5867 file name rather than a ZipInfo instance, so files are extracted with
5868 mode 0600 rather than 000 under Unix.
5869
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005870- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5871 argument in python 2.5, this broke code that subclassed Popen to include its
5872 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5881
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005882- Issue #2235: the C API function PyObject_HashNotImplemented and its
5883 interaction with the tp_hash slot (added in 2.6b2) are now documented
5884
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005885- Issue #643841: The language reference now provides more detailed
5886 coverage of the lookup process for special methods. The disclaimers
5887 regarding lack of coverage of new-style classes have also been
5888 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005891What's New in Python 2.6 beta 2?
5892================================
5893
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005894*Release date: 17-Jul-2008*
5895
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005896Core and Builtins
5897-----------------
5898
Georg Brandl3e483f62008-07-16 22:57:41 +00005899- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5900 its methods now allow for items objects that can be converted to
5901 an integer using operator.index().
5902
Mark Dickinson64b7e502008-07-16 09:40:03 +00005903- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5904 produced a ValueError instead of giving the correct float.
5905
Eric Smitha5fa5a22008-07-16 00:11:49 +00005906- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5907 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5908
Mark Dickinson7103aa42008-07-15 19:08:33 +00005909- Issue #3008: the float type has a new instance method 'float.hex'
5910 and a new class method 'float.fromhex' to convert floating-point
5911 numbers to and from hexadecimal strings, respectively.
5912
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005913- Issue #2235: __hash__ is once again inherited by default. To allow
5914 collections.Hashable to remain meaningful in the presence of the
5915 default hash implementation (object.__hash__), it is now possible
5916 to explicit block inheritance of hash by setting __hash__=None at
5917 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5918 level.
5919
Nick Coghlanb028f502008-07-13 14:52:36 +00005920- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5921 the parent module cannot be found while performing an absolute import.
5922 This means that an incorrectly defined __package__ attribute will
5923 now only prevent relative imports in that module rather than causing
5924 all imports from that module to fail.
5925
Nick Coghlan14ff9942008-07-08 14:21:42 +00005926- Issue #2517: Allow unicode messages in Exceptions again by correctly
5927 bypassing the instance dictionary when looking up __unicode__ on
5928 new-style classes.
5929
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005930- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5931 set to a custom object whose write() method happens to install
5932 another file in sys.stdout.
5933
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005934- Issue #3088: Corrected a race condition in classes derived from
5935 threading.local: the first member set by a thread could be saved in
5936 another thread's dictionary.
5937
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005938- Issue #3004: Minor change to slice.indices(): the start and stop
5939 arguments are now treated identically, making the behaviour easier
5940 to describe and understand. For example, slice(None, -10,
5941 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5942 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5943 10, -1).
5944
Georg Brandl278fc502008-07-19 12:46:12 +00005945- Issue #3219: Calling a function with repeated keyword arguments,
5946 f(a=2, a=23), would not cause a syntax error. This was a regression
5947 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005948
Georg Brandl278fc502008-07-19 12:46:12 +00005949- Issue #2862: Make int and float freelist management consistent with
5950 other freelists. Changes their CompactFreeList apis into
5951 ClearFreeList apis and calls them via gc.collect().

5957 api functions without holding the GIL, which could lead to a fatal
5958 error when they failed.
5959
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005960- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Georg Brandl5cc774e2008-06-11 20:28:06 +00006397 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006398
6399 This is controlled by the configure argument ``--with-universal-archs``:
6400
6401 - ``--with-universal-archs=all``: install 4-way universal
6402
6403 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6404
6405 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6406
6407 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006459- Issue #1631171: Re-implement the 'warnings' module in C (the
6460 original Python code has been kept as backup). This will allow for
6461 using the 'warning's machinery in such places as the parser where
6462 use of pure Python code is not possible. Both the ``showarning()``
6463 and ``formatwarning()`` gain an optional 'line' argument which is
6464 not called by default for backwards-compatibility reasons. Setting
6465 ``warnings.showwarning()`` to an implementation that lacks support
6466 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006491- The getpass module has been improved on Unix. It now uses /dev/tty
6492 by default and uses stderr instead of stdout. A GetPassWarning is

6514 file.close() is called while an object is in use by another thread
6515 an IOError exception will be raised and the file will not be closed.

6519 Modules/_ctypes/libffi/configure.ac.
6520
Georg Brandl3ee81df2008-05-17 18:14:43 +00006521- Issue #2385: distutils.core.run_script() makes __file__ available,
6522 so the controlled environment will more closely mirror the typical
6523 script environment. This supports setup.py scripts that refer to
6524 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006529- Issue #2550: The approach used by client/server code for obtaining
6530 ports to listen on in network-oriented tests has been refined in an
6531 effort to facilitate running multiple instances of the entire
6532 regression test suite in parallel without issue.
6533 test_support.bind_port() has been fixed such that it will always
6534 return a unique port -- which wasn't always the case with the
6535 previous implementation, especially if socket options had been set
6536 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6537 new implementation of bind_port() will actually raise an exception
6538 if it is passed an AF_INET/SOCK_STREAM socket with either the
6539 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6540 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6541 the socket it's been passed. This currently only applies to
6542 Windows. This option prevents any other sockets from binding to the
6543 host/port we've bound to, thus removing the possibility of the
6544 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6545 when a second SOCK_STREAM socket binds and accepts to a host/port
6546 that's already been bound by another socket. The optional preferred
6547 port parameter to bind_port() has been removed. Under no
6548 circumstances should tests be hard coding ports!
6549
6550 test_support.find_unused_port() has also been introduced, which will
6551 pass a temporary socket object to bind_port() in order to obtain an
6552 unused port. The temporary socket object is then closed and
6553 deleted, and the port is returned. This method should only be used
6554 for obtaining an unused port in order to pass to an external program
6555 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6556 a parameter to a server-oriented class that doesn't give you direct
6557 access to the underlying socket used.
6558
6559 Finally, test_support.HOST has been introduced, which should be used
6560 for the host argument of any relevant socket calls (i.e. bind and
6561 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006562
6563 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006564 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006565 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6566 test_asynchat and test_socket_ssl.
6567
Georg Brandl3ee81df2008-05-17 18:14:43 +00006568 It is now possible for multiple instances of the regression test
6569 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00006773- The bundled libffi copy is now in sync with the recently released
6774 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006775 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
6776 files are used. On all linux systems the --with-system-ffi
6777 configure option defaults to "yes".

Fred Drakea8ee94b2008-03-01 02:45:07 +00006838- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006839 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00006848- Added the future_builtins module, which contains hex() and oct().
6849 These are the PEP 3127 version of these functions, designed to be
6850 compatible with the hex() and oct() builtins from Python 3.0. They
6851 differ slightly in their output formats from the existing, unchanged
6852 Python 2.6 builtins. The expected usage of the future_builtins
6853 module is:
6854 from future_builtins import hex, oct
6855
Eric Smith7ef40bf2008-02-20 23:34:22 +00006856- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6857 exponents for exponents with absolute value < 100. Follows C99
6858 standard. This is a change on Windows, which would use 3 digits.
6859 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6860 so that any alterations it does to the resulting string will be
6861 available in stringlib/formatter.h (for float.__format__).
6862
Eric Smith5a3c1352008-02-19 13:21:56 +00006863- Implemented PEP 3101, Advanced String Formatting. This adds a new
6864 builtin format(); a format() method for str and unicode; a
6865 __format__() method to object, str, unicode, int, long, float, and
6866 datetime; the class string.Formatter; and the C API
6867 PyObject_Format().
6868
Georg Brandl3ee81df2008-05-17 18:14:43 +00006869- Fixed several potential crashes, all caused by specially crafted
6870 __del__ methods exploiting objects in temporarily inconsistent
6871 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006872
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006873- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006874 prevent a possible crash: an Abstract Base Class would try to access
6875 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006876

Georg Brandl3ee81df2008-05-17 18:14:43 +00006880- Clear all free lists during a gc.collect() of the highest generation
6881 in order to allow pymalloc to free more arenas. Python may give back
6882 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006883
Georg Brandl3ee81df2008-05-17 18:14:43 +00006884- Issue #2045: Fix an infinite recursion triggered when printing a
6885 subclass of collections.defaultdict, if its default_factory is set
6886 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006887
Christian Heimesf75dbef2008-02-08 00:11:31 +00006888- Fixed a minor memory leak in dictobject.c. The content of the free
6889 list was not freed on interpreter shutdown.
6890
Georg Brandl21e99f42010-03-07 15:23:59 +00006891- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006892 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006893
Georg Brandl3ee81df2008-05-17 18:14:43 +00006894- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6895 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006896 to compact the internal free lists of pre-allocted ints and floats.
6897
Georg Brandl3ee81df2008-05-17 18:14:43 +00006898- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6899 calls. Python expected the return type int but the fork familie
6900 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006901
Georg Brandl3ee81df2008-05-17 18:14:43 +00006902- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00006914- Patch #1473257: generator objects gain a gi_code attribute. This is
6915 the same object as the func_code attribute of the function that
6916 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006917
Georg Brandl3ee81df2008-05-17 18:14:43 +00006918- Issue #1920: "while 0" statements were completely removed by the
6919 compiler, even in the presence of an "else" clause, which is
6920 supposed to be run when the condition is false. Now the compiler
6921 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006922
Guido van Rossumeead05f2008-01-24 18:21:02 +00006923- A few crashers fixed: weakref_in_del.py (issue #1377858);
6924 loosing_dict_ref.py (issue #1303614, test67.py);
6925 borrowed_ref_[34].py (not in tracker).
6926
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006927- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006928 suppressed while an extension is loaded by calling SetErrorMode in
6929 dynload_win.c. The error is still reported properly.
6930
Georg Brandl3ee81df2008-05-17 18:14:43 +00006931- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006932 several extension methods and modules do not work without unicode
6933 support.
6934
Georg Brandl26543b12008-01-21 18:36:51 +00006935- Issue #1882: when compiling code from a string, encoding cookies in the
6936 second line of code were not always recognized correctly.
6937
Georg Brandl14404b62008-01-19 19:27:05 +00006938- Issue #1679: "0x" was taken as a valid integer literal.
6939
Georg Brandl6caad7d2008-01-26 14:19:22 +00006940- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006941 added.
6942
Christian Heimesc94e2b52008-01-14 04:13:37 +00006943- sys.float_info / PyFloat_GetInfo: The floating point information
6944 object was converted from a dict to a specialized structseq object.
6945
Georg Brandl3ee81df2008-05-17 18:14:43 +00006946- Patch #1816: Added sys.flags structseq. It exposes the status of
6947 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006948
Georg Brandl3ee81df2008-05-17 18:14:43 +00006949- Objects/structseq.c: Implemented new structseq representation. The
6950 patch makes structseqs (e.g. the return value of os.stat) more
6951 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006952
Georg Brandl3ee81df2008-05-17 18:14:43 +00006953- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00006975 and INF. float("nan"), float("inf") and float("-inf") now work on
6976 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006977
Georg Brandl3ee81df2008-05-17 18:14:43 +00006978- Compiler now generates simpler and faster code for dictionary
6979 literals. The oparg for BUILD_MAP now indicates an estimated
6980 dictionary size. There is a new opcode, STORE_MAP, for adding
6981 entries to the dictionary.

7017 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007018
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007019- sets and frozensets now have an isdisjoint() method.

Neal Norwitz44f326e2007-10-05 05:29:17 +00007023- Fix warnings found by the new version of the Coverity checker.
7024
Georg Brandl21e99f42010-03-07 15:23:59 +00007025- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007026 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7027 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007028
Georg Brandl3ee81df2008-05-17 18:14:43 +00007029- Issue #1686386: Tuple's tp_repr did not take into account the
7030 possibility of having a self-referential tuple, which is possible
7031 from C code. Nor did object's tp_str consider that a type's tp_str
7032 could do something that could lead to an inifinite recursion.
7033 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7034 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007035
Georg Brandl3ee81df2008-05-17 18:14:43 +00007036- Issue #1164: It was possible to trigger deadlock when using the
7037 'print' statement to write to a file since the GIL was not released
7038 as needed. Now PyObject_Print() does the right thing along with
7039 various tp_print implementations of the built-in types and those in
7040 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007041
Georg Brandl3ee81df2008-05-17 18:14:43 +00007042- Issue #1147: Exceptions were directly allowing string exceptions in
7043 their throw() method even though string exceptions no longer
7044 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00007048
Brett Cannon1e534b52007-09-07 04:18:30 +00007049- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007050 PyObject_Call() never calling back out to Python code to trigger
7051 recursion depth updates/checks. Required the creation of a static
7052 RuntimeError instance in case normalizing an exception put the
7053 recursion check value past its limit. Fixes crashers
7054 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007055

Neal Norwitz0ac60192007-05-27 04:08:54 +00007069- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007070 __*__ attributes. (Some already existed, e.g., __doc__ and
7071 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007072
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007073- Add -3 option to the interpreter to warn about features that are
7074 deprecated and will be changed/removed in Python 3.0.
7075
Georg Brandl2134e752007-05-21 20:34:16 +00007076- Patch #1686487: you can now pass any mapping after '**' in function
7077 calls.
7078
Collin Winter62903052007-05-18 23:11:24 +00007079- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007080 "except E as target:". This is to provide forwards compatibility
7081 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007088- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007089 setting a plain string, ie don't expand to single letter identifiers.
7090
Raymond Hettinger13936692007-04-11 18:40:58 +00007091- Request #1191699: Slices can now be pickled.
7092
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007093- Request #1193128: str.translate() now allows a None argument for
7094 translations that only remove characters without re-mapping the
7095 remaining characters.
7096
Georg Brandl5cb76c12007-03-21 09:00:39 +00007097- Patch #1682205: a TypeError while unpacking an iterable is no longer

7101
Guido van Rossum143b5642007-03-23 04:58:42 +00007102- Bug #1683368: The object.__init__() and object.__new__() methods are
7103 now stricter in rejecting excess arguments. The only time when
7104 either allows excess arguments is when it is not overridden and the
7105 other one is. For backwards compatibility, when both are
7106 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007107 warning later). Also, type.__init__() insists on the same signature
7108 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007109
Georg Brandl3ee81df2008-05-17 18:14:43 +00007110- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7111 object to complex using its __complex__() method before falling back
7112 to the __float__() method. Therefore, the functions in the cmath
7113 module now can operate on objects that define a __complex__()
7114 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007115
Georg Brandl3ee81df2008-05-17 18:14:43 +00007116- Patch #1623563: allow __class__ assignment for classes with

7125 its type.

7131
Georg Brandl7b9c5552007-03-12 14:30:05 +00007132- Bug #1678647: write a newline after printing an exception in any
7133 case, even when converting the value to a string failed.
7134
Georg Brandl871f1bc2007-03-12 13:17:36 +00007135- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007136 its argument, if it exists. If not, it will work like before. This
7137 allows customizing the output of dir() in the presence of a
7138 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007146- Patch #1491866: change the complex() constructor to allow
7147 parthensized forms. This means complex(repr(x)) now works instead of
7148 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007149
Georg Brandlaa2321b2007-03-07 00:40:28 +00007150- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007151 makes the filenames the warning module prints much more sensible
7152 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007153

Georg Brandl0fca97a2007-03-05 22:28:08 +00007165- Patch #1674228: when assigning a slice (old-style), check for the
7166 sq_ass_slice instead of the sq_slice slot.
7167
Georg Brandl3ee81df2008-05-17 18:14:43 +00007168- When printing an unraisable error, don't print exceptions. before
7169 the name. This duplicates the behavior whening normally printing
7170 exceptions.

7796 accepted in TestSuite.addTest(). This should cause no
7797 incompatibility since it never made sense with ordinary subclasses
7798 -- the failure just occurred later, with a more cumbersome
7799 exception.

8012 partial fix for Bug #1574584.
8013
Georg Brandl3ee81df2008-05-17 18:14:43 +00008014- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008080- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8081 with RFC 3207 and forgets any knowledge obtained from the server not
8082 obtained from the TLS negotiation itself. Patch contributed by Bill
8083 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008084
Georg Brandl3ee81df2008-05-17 18:14:43 +00008085- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008086 that the SMTP.starttls() caller no longer needs to call ehlo()
8087 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008088 does not claim to support starttls. Adds the
8089 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8090 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008144- itertools.chain() now has an alternate constructor,

8159 contents before adding elements from the iterable. This fix brings
8160 the behavior into line with that for list.__init__().

8170 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8171 silently miscode subclasses of those types. Now, it raises a
8172 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008173

Georg Brandl3ee81df2008-05-17 18:14:43 +00008188 time so that opening a database previously created with the DB_DUP
8189 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8190 opens. Specifically: dictionary assignment to a DB object will
8191 replace all values for a given key when the database allows
8192 duplicate values. DB users should use DB.put(k, v) when they want
8193 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008194

8200 characters with ASCII value less than 32. Also, it correctly quotes
8201 dots only if they occur on a single line, as opposed to the previous
8202 behavior of quoting dots if they are the second character of any
8203 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008204

8527
Georg Brandl3ee81df2008-05-17 18:14:43 +00008528- Unified naming convention for free lists and their limits. All free
8529 lists in Object/ are named ``free_list``, the counter ``numfree``
8530 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8531 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008532
Georg Brandl3ee81df2008-05-17 18:14:43 +00008533- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8534 to ``PyTuple_SetItem``, it can be used to populate a brand new
8535 frozenset; but it does not steal a reference to the added item.

8547
Georg Brandl3ee81df2008-05-17 18:14:43 +00008548- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8549 of w# format code incorrectly truncated the length to an int, even
8550 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8551 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008552
Georg Brandl3ee81df2008-05-17 18:14:43 +00008553- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8571- Fix some leftovers from the conversion from int to Py_ssize_t
8572 (relevant to strings and sequences of more than 2**31 items).
8573
8574- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8575 outside of pystate.c and should not be necessary.
8576
Georg Brandl3ee81df2008-05-17 18:14:43 +00008577- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8578 absolute imports. In earlier versions they might have used relative
8579 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008580
Georg Brandl3ee81df2008-05-17 18:14:43 +00008581- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8582 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008583
Georg Brandl3ee81df2008-05-17 18:14:43 +00008584- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

8594 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008595

Georg Brandl3ee81df2008-05-17 18:14:43 +00008609- Removed the macfs module. It had been deprecated since Python 2.5.
8610 This lead to the deprecation of macostools.touched() as it relied
8611 solely on macfs and was a no-op under OS X.
