25 the same behaviour than the print statement.
26
Antoine Pitrou9cf85f12010-09-01 21:17:34 +000027- Issue #9737: Fix a crash when trying to delete a slice or an item from

71 characters that appear inside quoted strings in email addresses.
72
R. David Murray20ad3632010-10-01 15:48:49 +000073- Issue #10004: quoprimime no longer generates a traceback when confronted
74 with invalid characters after '=' in a Q-encoded word.

88
Antoine Pitrou6391b342010-09-14 18:48:19 +000089- Issue #9854: The default read() implementation in io.RawIOBase now
90 handles non-blocking readinto() returning None correctly.
91
Antoine Pitrouf7f390a2010-09-14 14:37:18 +000092- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
93 SSLSocket.sendto() to match the corresponding socket methods. Also,
94 fix various SSLSocket methods to raise socket.error rather than an
95 unhelpful TypeError when called on an unconnected socket. Original patch
96 by Andrew Bennetts.
97
Raymond Hettinger74f869e2010-09-13 22:14:36 +000098- Issue #9826: OrderedDict.__repr__ can now handle self-referential

Raymond Hettinger20397532010-09-12 02:11:45 +0000106- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
107 This prevents user-created self-referencing ordered dictionaries from
108 becoming permanently uncollectable GC garbage. The downside is that
109 removing __del__ means that the internal doubly-linked list has to wait for
110 GC collection rather than freeing memory immediately when the refcnt drops
111 to zero.
112
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000113- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000114 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000115 value.
116
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000117- Issue #9792: In case of connection failure, socket.create_connection()
118 would swallow the exception and raise a new one, making it impossible
119 to fetch the original errno, or to filter timeout errors. Now the
120 original error is re-raised.
121
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000122- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
123 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
124 be updated back after the system call. Original patch by Brian Brazil.
125
Antoine Pitroudca9de92010-09-04 17:52:26 +0000126- Issue #1100562: Fix deep-copying of objects derived from the list and
127 dict types. Patch by Michele Orrù and Björn Lindqvist.
128
Fred Drakea1e627d2010-09-03 03:55:50 +0000129- Issue #7005: Fixed output of None values for RawConfigParser.write and
130 ConfigParser.write.
131
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000132- Issue #808164: Fixed socket.close to avoid references to globals, to
133 avoid issues when socket.close is called from a __del__ method.
134
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000135- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

137
R. David Murray7c4bf552010-08-25 01:45:57 +0000138- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
139 character years even if the message contains RFC822 two character years.
140
Daniel Stutzbach91287322010-08-24 21:09:30 +0000141- Issue #8750: Fixed MutableSet's methods to correctly handle
142 reflexive operations, namely x -= x and x ^= x.
143
Victor Stinnercaafd772010-09-08 10:51:01 +0000144- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

153 module now correctly return a set. (Patch by Eli Bendersky.)
154
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000155- Issue #9617: Signals received during a low-level write operation aren't
156 ignored by the buffered IO layer anymore.
157
Benjamin Peterson52c36052010-08-21 03:03:22 +0000158- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
159 are not held onto after they are deleted elsewhere.
160
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000161- Issue #9626: the view methods for collections.OrderedDict() were returning
162 the unordered versions inherited from dict. Those methods are now
163 overridden to provide ordered views.
164
Éric Araujo0389ae62010-08-14 03:07:46 +0000165- Issue #8688: MANIFEST files created by distutils now include a magic

167 without this marker will not be overwritten or removed.
168
Antoine Pitroue1436d12010-08-12 15:25:51 +0000169- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

172
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000173- Issue #9550: a BufferedReader could issue an additional read when the

558 of the number of bytes specified by the start byte.
559 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000917 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
918 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
919 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

939Core and Builtins
940-----------------
941
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000942- Issue #7301: Add environment variable $PYTHONWARNINGS.
943
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000944- Issue #8329: Don't return the same lists from select.select when no fds are
945 changed.
946
Georg Brandlfee0f442010-05-22 21:26:21 +0000947- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000948 on 64-bit machines. The shift count for either left or right shift is
949 permitted to be up to sys.maxsize.
950
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000951- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000955- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
956
Georg Brandlfee0f442010-05-22 21:26:21 +0000957- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
958 with a non-empty format string. This is an effort to future-proof user
959 code. If a derived class does not currently implement __format__ but later
960 adds its own __format__, it would most likely break user code that had
961 supplied a format string. This will be changed to a DeprecationWaring in
962 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000963
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000964- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000989- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000990 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

994
Georg Brandlfee0f442010-05-22 21:26:21 +0000995- Issue #8257: The Decimal construct now accepts a float instance directly,
996 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000997
998 >>> Decimal(1.1)

1000
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001001- collections.Counter() now supports a subtract() method.
1002
Georg Brandlfee0f442010-05-22 21:26:21 +00001003- The functools module now has a total_ordering() class decorator to simplify
1004 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001005
Georg Brandlfee0f442010-05-22 21:26:21 +00001006- The functools module also adds cmp_to_key() as a tool to transition old-style
1007 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001008
Georg Brandlfee0f442010-05-22 21:26:21 +00001009- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1010 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001011
Georg Brandlfee0f442010-05-22 21:26:21 +00001012- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1013 InvalidOperation instead of returning False. (Comparisons involving a quiet
1014 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1015 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001016
Georg Brandlfee0f442010-05-22 21:26:21 +00001017- Issue #2531: Comparison operations between floats and Decimal instances now
1018 return a result based on the numeric values of the operands; previously they
1019 returned an arbitrary result based on the relative ordering of id(float) and
1020 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001021
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001022- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001023 argument `-` which tells it to read files to compile from stdin. Each line is
1024 read on demand and the named file is compiled immediately. (Original patch by
1025 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001026
Georg Brandlfee0f442010-05-22 21:26:21 +00001027- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001030- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1031 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001032 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001033
Georg Brandlfee0f442010-05-22 21:26:21 +00001034- Comparisons using one of <, <=, >, >= between a complex instance and a
1035 Fractions instance now raise TypeError instead of returning True/False. This
1036 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1037 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001038
Michael Foorde6410c52010-03-29 20:04:23 +00001039- Addition of ``WeakSet`` to the ``weakref`` module.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001048- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001049 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Florent Xicluna9e7a4c92010-03-22 16:07:38 +00001052- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
1053 deprecated.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001092- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001093 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1094 log file to compute the next rollover time. If the log file does not exist,
1095 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00001096

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001136- Issue #8300: When passing a non-integer argument to struct.pack with any
1137 integer format code, struct.pack first attempts to convert the non-integer
1138 using its __index__ method. If that method is non-existent or raises
1139 TypeError it goes on to try the __int__ method, as described below.
1140
Georg Brandlba83f822010-03-14 09:50:54 +00001141- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1142 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1143 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001144 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1145 inconsistent: __int__ was used for some integer codes but not for others, and
1146 the set of integer codes for which it was used differed between native packing
1147 and standard packing.)

1396 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1397 returning NULL. The macro now returns a statically allocated empty string
1398 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00001444 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001450- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001451 file position when calling `truncate()`. It would previously change the file
1452 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001453 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1454
Georg Brandlba83f822010-03-14 09:50:54 +00001455- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1456 class used to represent files stored inside an archive. The new
1457 implementation is significantly faster and can be wrapped in a
1458 ``io.BufferedReader`` object for more speedups. It also solves an issue
1459 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1460 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00001469
Georg Brandlba83f822010-03-14 09:50:54 +00001470- Issue #7748: Since unicode values are supported for some metadata options in
1471 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1472 encoded string for them. This ensures that the upload and register commands
1473 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001744- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1745 decimal string that's guaranteed to round back to x under correct rounding
1746 (with round-half-to-even rounding mode). Previously it gave a string based on
1747 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1748 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1749 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001750
Georg Brandlba83f822010-03-14 09:50:54 +00001751- Issue #7117: On almost all platforms: float-to-string and string-to-float
1752 conversions within Python are now correctly rounded. Places these conversions
1753 occur include: str for floats and complex numbers; the float and complex
1754 constructors; old-style and new-style numeric formatting; serialization and
1755 deserialization of floats and complex numbers using marshal, pickle and json;
1756 parsing of float and imaginary literals in Python code; Decimal-to-float
1757 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001758
Georg Brandlba83f822010-03-14 09:50:54 +00001759 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1760 providing correctly-rounded strtod and dtoa C functions. This code is
1761 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1762 the C compiler. There may be a small number of platforms on which correct
1763 operation of this code cannot be guaranteed, so the code is not used: notably,
1764 this applies to platforms where the C double format is not IEEE 754 binary64,
1765 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1766 and Python's configure script is unable to determine how to change the FPU
1767 precision. On these platforms conversions use the platform strtod and dtoa,
1768 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001769
Georg Brandlba83f822010-03-14 09:50:54 +00001770- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1771 uses the correctly-rounded string <-> float conversions described above (when
1772 available), and so produces correctly rounded results that will display nicely
1773 under the float repr. There are two related small changes: (1) round now
1774 accepts any class with an ``__index__()`` method for its second argument (but
1775 no longer accepts floats for the second argument), and (2) an excessively
1776 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1777 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001924- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1925 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1926 but with at least one decimal point and with a default precision
1927 of 12. Previously, the behavior the same but with a default precision of 6.
1928 This more closely matches ``str()``, and reduces surprises when adding
1929 alignment flags to the empty presentation type. This also affects the new
1930 complex.__format__ in the same way.
1931

2127
Georg Brandlba83f822010-03-14 09:50:54 +00002128- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2129 file objects with closefd=False. The file descriptor is still kept open but
2130 the file object behaves like a closed file. The ``FileIO`` object also got a

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002151- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002154- On windows, ``os.chdir()`` given unicode was not working if
2155 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2156 this code path is really executed because I cannot move to such directory on
2157 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002159- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2160 element is temporarily replaced with an equivalent frozenset. But the
2161 eventual KeyError would always report the empty ``frozenset()`` as the missing
2162 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002182- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2183 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2184 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2185 of using the replace error handler in PyUnicode_DecodeUTF8().
2186
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002187- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002190- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2192 gives improved memory leak detection when running under Valgrind, while taking
2193 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003416 leak-chasing test runs give sensible results. The previous method of reaping
3417 threads could return successfully while some Thread objects were still
3418 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00003435- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3436 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003437 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3438 the tests if DISPLAY is defined but can't be used.

3444 import both normal and optimised versions of modules. test_heapq and
3445 test_warnings have been adjusted to use it, tests for other modules with both
3446 C and Python implementations in the stdlib can be adjusted to use it over
3447 time.

Georg Brandlba83f822010-03-14 09:50:54 +00003455- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3456 should cause a test to be skipped are now done using import_module from test
3457 support, which does the conversion.

3559
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003560- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3561 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3562 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3563 ``printf`` function, whereas PyString_FromFormat has an independent
3564 implementation and uses "%zd" on all platforms for size_t values.
3565 This makes a difference on win64, where ``printf`` needs "%Id" to display
3566 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003568- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3572 object; previously an int would be returned for small values. the __long__
3573 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00003585- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003586 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3587 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3588 when given a tuple of classes as second argument, were looking up
3589 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3590 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003729What's New in Python 2.6 beta 3?
3730================================
3731
Barry Warsaw07a4a382008-08-21 01:15:08 +00003732*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003733
3734Core and Builtins
3735-----------------
3736
Guido van Rossumf8402962008-08-20 15:01:50 +00003737- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3738 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3739 extensions do not automatically benefit from the class attribute
3740 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3741 to their tp_flags field if they care. This is a backwards
3742 compatibility feature; in 3.0, all types will use the cache by
3743 default.
3744
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003745- Keyword arguments can now follow starred arguments. (``f(a, *args,
3746 keyword=23)`` is now valid syntax.)
3747
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003748- ctypes function pointers that are COM methods have a boolean True
3749 value again.
3750
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003751- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3752 by denying s# to parse objects that have a releasebuffer procedure,
3753 and introducing s*.
3754
Georg Brandl1e13ea92008-08-11 09:07:59 +00003755- Issue #3537: Fix an assertion failure when an empty but presized dict
3756 object was stored in the freelist.
3757
Mark Dickinsonb6467572008-08-04 21:30:09 +00003758- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3759 ValueError consistently across platforms.
3760
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003761- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3762 (64bit Unix, for example), unichr() would truncate its argument and return
3763 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3764
Neal Norwitze7d8be82008-07-31 17:17:14 +00003765- Apply security patches from Apple.
3766
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003767- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3768 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3769
Antoine Pitrou92f82162008-07-25 22:22:08 +00003770- Issue #1819: function calls with several named parameters are now on
3771 average 35% faster (as measured by pybench).
3772
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003773- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3774 the python debugger steps into a class statement: the free variables (local
3775 variables defined in an outer scope) would be deleted from the outer scope.
3776
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003777- Issue #2620: Overflow checking when allocating or reallocating memory
3778 was not always being done properly in some python types and extension
3779 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3780 all been updated to perform better checks and places in the code that
3781 would previously leak memory on the error path when such an allocation
3782 failed have been fixed.
3783
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003784Library
3785-------
3786
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003787- Issue #3612: Added some missing basic types in ctypes.wintypes.
3788
Benjamin Petersone977ad42008-08-20 01:42:01 +00003789- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3790 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3791
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003792- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3793 version reported by these tools does not necessarily follow the python
3794 version numbering scheme, so the module is less strict when parsing it.
3795
Nick Coghlanf70385a2008-08-18 12:42:46 +00003796- Issue #2235: Added Py3k warnings for types which will become unhashable
3797 under the stricter __hash__ inheritance rules in 3.0. Several types
3798 which did not meet the rules for hash invariants and were already
3799 unhashable in 3.0 have now been explicitly flagged as unhashable in
3800 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3801 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3802
Brett Cannon88f801d2008-08-18 00:46:22 +00003803- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3804 imported into the module but exposed as part of the module's API.
3805
Brett Cannon7b96f072008-08-18 00:41:11 +00003806- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3807
Brett Cannon46225e72008-08-18 00:36:52 +00003808- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3809
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003810- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3811
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003812- Issue #3575: Incremental decoder's decode function now takes bytearray
3813 by using 's*' instead of 't#'.
3814
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003815- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003816 fails unicode conversion on 2nd parameter. (windows only)
3817
Georg Brandl222e2082010-08-01 22:27:39 +00003818- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003819 in a redirect.
3820
Brett Cannonabe423e2008-08-16 21:47:07 +00003821- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003822 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003823
Facundo Batistaeb90b782008-08-16 14:44:07 +00003824- Issue #2776: fixed small issue when handling an URL with double slash
3825 after a 302 response in the case of not going through a proxy.
3826
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003827- Issue #2676: in the email package, content-type parsing was hanging on
3828 pathological input because of quadratic or exponential behaviour of a
3829 regular expression.
3830
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003831- Issue #3476: binary buffered reading through the new "io" library is now
3832 thread-safe.
3833
Brett Cannonbf3157b2008-08-14 05:00:03 +00003834- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3835 since mimetools itself is deprecated. Because modules are cached, all
3836 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3837
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003838- Issue #3134: shutil referenced undefined WindowsError symbol.
3839
Robert Schuppenies14646332008-08-10 11:01:53 +00003840- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3841 menu entries were not deleted.
3842
Brett Cannon83e81842008-08-09 23:30:55 +00003843- Copied the implementation of reduce() to _functools.reduce() to have a
3844 version that did not raise a DeprecationWarning under -3.
3845
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003846- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3847 a MemoryError rather than silently stop the iteration.
3848
Guido van Rossum59ce9012008-08-09 14:55:34 +00003849- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3850 to _sre.compile() will now be rejected. This should not affect anybody
3851 since the re.compile() function never generates invalid re-bytecode.
3852
Skip Montanaroa032bf42008-08-08 22:52:51 +00003853- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3854 upon first access it can be automatically initialized from the csv file if
3855 it wasn't initialized during instantiation.
3856
Brett Cannon3aa2a492008-08-06 22:28:09 +00003857- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3858 the reload() built-in has been removed.
3859
Brett Cannon7e30b672008-08-04 21:52:25 +00003860- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003861 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3864 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3865 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3866 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003867
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003868- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3869 raised an AttributeError.
3870
Benjamin Peterson01a24322008-07-28 23:35:27 +00003871- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003872 asking for a specific length. This problem only affected files opened
3873 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003874
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003875- Issue #3449: Update decimal module to use most recent specification
3876 (v. 1.68) and tests (v. 2.58) from IBM.
3877
Georg Brandl222e2082010-08-01 22:27:39 +00003878- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

3882
Georg Brandlf9efabb2008-07-23 15:16:45 +00003883- Deprecate the "ast" parser function aliases.
3884
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003885- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3886
3887- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3888 invalid arguments.
3889
3890- Issue #3302: Fix several crashes when calling locale's gettext functions
3891 with None arguments.
3892
3893- Issue #3389: Allow resolving dotted names for handlers in logging
3894 configuration files.
3895

3897
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003898- Issue #3394: zipfile.writestr sets external attributes when passed a
3899 file name rather than a ZipInfo instance, so files are extracted with
3900 mode 0600 rather than 000 under Unix.
3901
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003902- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3903 argument in python 2.5, this broke code that subclassed Popen to include its
3904 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3913
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003914- Issue #2235: the C API function PyObject_HashNotImplemented and its
3915 interaction with the tp_hash slot (added in 2.6b2) are now documented
3916
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003917- Issue #643841: The language reference now provides more detailed
3918 coverage of the lookup process for special methods. The disclaimers
3919 regarding lack of coverage of new-style classes have also been
3920 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003923What's New in Python 2.6 beta 2?
3924================================
3925
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003926*Release date: 17-Jul-2008*
3927
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003928Core and Builtins
3929-----------------
3930
Georg Brandl3e483f62008-07-16 22:57:41 +00003931- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3932 its methods now allow for items objects that can be converted to
3933 an integer using operator.index().
3934
Mark Dickinson64b7e502008-07-16 09:40:03 +00003935- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3936 produced a ValueError instead of giving the correct float.
3937
Eric Smitha5fa5a22008-07-16 00:11:49 +00003938- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3939 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3940
Mark Dickinson7103aa42008-07-15 19:08:33 +00003941- Issue #3008: the float type has a new instance method 'float.hex'
3942 and a new class method 'float.fromhex' to convert floating-point
3943 numbers to and from hexadecimal strings, respectively.
3944
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003945- Issue #2235: __hash__ is once again inherited by default. To allow
3946 collections.Hashable to remain meaningful in the presence of the
3947 default hash implementation (object.__hash__), it is now possible
3948 to explicit block inheritance of hash by setting __hash__=None at
3949 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3950 level.
3951
Nick Coghlanb028f502008-07-13 14:52:36 +00003952- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3953 the parent module cannot be found while performing an absolute import.
3954 This means that an incorrectly defined __package__ attribute will
3955 now only prevent relative imports in that module rather than causing
3956 all imports from that module to fail.
3957
Nick Coghlan14ff9942008-07-08 14:21:42 +00003958- Issue #2517: Allow unicode messages in Exceptions again by correctly
3959 bypassing the instance dictionary when looking up __unicode__ on
3960 new-style classes.
3961
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003962- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3963 set to a custom object whose write() method happens to install
3964 another file in sys.stdout.
3965
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003966- Issue #3088: Corrected a race condition in classes derived from
3967 threading.local: the first member set by a thread could be saved in
3968 another thread's dictionary.
3969
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003970- Issue #3004: Minor change to slice.indices(): the start and stop
3971 arguments are now treated identically, making the behaviour easier
3972 to describe and understand. For example, slice(None, -10,
3973 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3974 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3975 10, -1).
3976
Georg Brandl278fc502008-07-19 12:46:12 +00003977- Issue #3219: Calling a function with repeated keyword arguments,
3978 f(a=2, a=23), would not cause a syntax error. This was a regression

Georg Brandl5cc774e2008-06-11 20:28:06 +00004429 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004430
4431 This is controlled by the configure argument ``--with-universal-archs``:
4432

4434
4435 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4436
4437 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4438

Georg Brandl3ee81df2008-05-17 18:14:43 +00004491- Issue #1631171: Re-implement the 'warnings' module in C (the
4492 original Python code has been kept as backup). This will allow for
4493 using the 'warning's machinery in such places as the parser where
4494 use of pure Python code is not possible. Both the ``showarning()``
4495 and ``formatwarning()`` gain an optional 'line' argument which is
4496 not called by default for backwards-compatibility reasons. Setting
4497 ``warnings.showwarning()`` to an implementation that lacks support
4498 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004561- Issue #2550: The approach used by client/server code for obtaining
4562 ports to listen on in network-oriented tests has been refined in an
4563 effort to facilitate running multiple instances of the entire
4564 regression test suite in parallel without issue.
4565 test_support.bind_port() has been fixed such that it will always
4566 return a unique port -- which wasn't always the case with the
4567 previous implementation, especially if socket options had been set
4568 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4569 new implementation of bind_port() will actually raise an exception
4570 if it is passed an AF_INET/SOCK_STREAM socket with either the
4571 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4572 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4573 the socket it's been passed. This currently only applies to
4574 Windows. This option prevents any other sockets from binding to the
4575 host/port we've bound to, thus removing the possibility of the
4576 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4577 when a second SOCK_STREAM socket binds and accepts to a host/port
4578 that's already been bound by another socket. The optional preferred
4579 port parameter to bind_port() has been removed. Under no
4580 circumstances should tests be hard coding ports!
4581
4582 test_support.find_unused_port() has also been introduced, which will
4583 pass a temporary socket object to bind_port() in order to obtain an
4584 unused port. The temporary socket object is then closed and
4585 deleted, and the port is returned. This method should only be used
4586 for obtaining an unused port in order to pass to an external program
4587 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4588 a parameter to a server-oriented class that doesn't give you direct
4589 access to the underlying socket used.
4590
4591 Finally, test_support.HOST has been introduced, which should be used
4592 for the host argument of any relevant socket calls (i.e. bind and
4593 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004594
4595 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004596 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004597 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4598 test_asynchat and test_socket_ssl.
4599
Georg Brandl3ee81df2008-05-17 18:14:43 +00004600 It is now possible for multiple instances of the regression test
4601 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004880- Added the future_builtins module, which contains hex() and oct().
4881 These are the PEP 3127 version of these functions, designed to be
4882 compatible with the hex() and oct() builtins from Python 3.0. They
4883 differ slightly in their output formats from the existing, unchanged
4884 Python 2.6 builtins. The expected usage of the future_builtins
4885 module is:
4886 from future_builtins import hex, oct
4887
Eric Smith7ef40bf2008-02-20 23:34:22 +00004888- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4889 exponents for exponents with absolute value < 100. Follows C99
4890 standard. This is a change on Windows, which would use 3 digits.
4891 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4892 so that any alterations it does to the resulting string will be
4893 available in stringlib/formatter.h (for float.__format__).
4894
Eric Smith5a3c1352008-02-19 13:21:56 +00004895- Implemented PEP 3101, Advanced String Formatting. This adds a new
4896 builtin format(); a format() method for str and unicode; a
4897 __format__() method to object, str, unicode, int, long, float, and
4898 datetime; the class string.Formatter; and the C API
4899 PyObject_Format().
4900
Georg Brandl3ee81df2008-05-17 18:14:43 +00004901- Fixed several potential crashes, all caused by specially crafted
4902 __del__ methods exploiting objects in temporarily inconsistent
4903 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004904
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004905- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004906 prevent a possible crash: an Abstract Base Class would try to access
4907 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004908

Georg Brandl3ee81df2008-05-17 18:14:43 +00004912- Clear all free lists during a gc.collect() of the highest generation
4913 in order to allow pymalloc to free more arenas. Python may give back
4914 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004915
Georg Brandl3ee81df2008-05-17 18:14:43 +00004916- Issue #2045: Fix an infinite recursion triggered when printing a
4917 subclass of collections.defaultdict, if its default_factory is set
4918 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004919
Christian Heimesf75dbef2008-02-08 00:11:31 +00004920- Fixed a minor memory leak in dictobject.c. The content of the free
4921 list was not freed on interpreter shutdown.
4922
Georg Brandl21e99f42010-03-07 15:23:59 +00004923- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004924 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004925
Georg Brandl3ee81df2008-05-17 18:14:43 +00004926- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4927 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004928 to compact the internal free lists of pre-allocted ints and floats.
4929
Georg Brandl3ee81df2008-05-17 18:14:43 +00004930- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4931 calls. Python expected the return type int but the fork familie
4932 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004933
Georg Brandl3ee81df2008-05-17 18:14:43 +00004934- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004946- Patch #1473257: generator objects gain a gi_code attribute. This is
4947 the same object as the func_code attribute of the function that
4948 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004949
Georg Brandl3ee81df2008-05-17 18:14:43 +00004950- Issue #1920: "while 0" statements were completely removed by the
4951 compiler, even in the presence of an "else" clause, which is
4952 supposed to be run when the condition is false. Now the compiler
4953 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004954
Guido van Rossumeead05f2008-01-24 18:21:02 +00004955- A few crashers fixed: weakref_in_del.py (issue #1377858);
4956 loosing_dict_ref.py (issue #1303614, test67.py);
4957 borrowed_ref_[34].py (not in tracker).
4958
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004959- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004960 suppressed while an extension is loaded by calling SetErrorMode in
4961 dynload_win.c. The error is still reported properly.
4962
Georg Brandl3ee81df2008-05-17 18:14:43 +00004963- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004964 several extension methods and modules do not work without unicode
4965 support.
4966
Georg Brandl26543b12008-01-21 18:36:51 +00004967- Issue #1882: when compiling code from a string, encoding cookies in the
4968 second line of code were not always recognized correctly.
4969
Georg Brandl14404b62008-01-19 19:27:05 +00004970- Issue #1679: "0x" was taken as a valid integer literal.
4971
Georg Brandl6caad7d2008-01-26 14:19:22 +00004972- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004973 added.
4974
Christian Heimesc94e2b52008-01-14 04:13:37 +00004975- sys.float_info / PyFloat_GetInfo: The floating point information
4976 object was converted from a dict to a specialized structseq object.
4977
Georg Brandl3ee81df2008-05-17 18:14:43 +00004978- Patch #1816: Added sys.flags structseq. It exposes the status of
4979 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004980
Georg Brandl3ee81df2008-05-17 18:14:43 +00004981- Objects/structseq.c: Implemented new structseq representation. The

5011 literals. The oparg for BUILD_MAP now indicates an estimated
5012 dictionary size. There is a new opcode, STORE_MAP, for adding
5013 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005042- Patch #1739468: Directories and zipfiles containing a __main__.py
5043 file can now be directly executed by passing their name to the
5044 interpreter. The directory/zipfile is automatically inserted as the
5045 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005047- Issue #1265: Fix a problem with sys.settrace, if the tracing
5048 function uses a generator expression when at the same time the
5049 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005050
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005051- sets and frozensets now have an isdisjoint() method.

5054
Neal Norwitz44f326e2007-10-05 05:29:17 +00005055- Fix warnings found by the new version of the Coverity checker.
5056
Georg Brandl21e99f42010-03-07 15:23:59 +00005057- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005058 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5059 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005060
Georg Brandl3ee81df2008-05-17 18:14:43 +00005061- Issue #1686386: Tuple's tp_repr did not take into account the
5062 possibility of having a self-referential tuple, which is possible
5063 from C code. Nor did object's tp_str consider that a type's tp_str
5064 could do something that could lead to an inifinite recursion.
5065 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5066 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005067
Georg Brandl3ee81df2008-05-17 18:14:43 +00005068- Issue #1164: It was possible to trigger deadlock when using the
5069 'print' statement to write to a file since the GIL was not released
5070 as needed. Now PyObject_Print() does the right thing along with
5071 various tp_print implementations of the built-in types and those in
5072 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005073
Georg Brandl3ee81df2008-05-17 18:14:43 +00005074- Issue #1147: Exceptions were directly allowing string exceptions in
5075 their throw() method even though string exceptions no longer
5076 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005077
Georg Brandl3ee81df2008-05-17 18:14:43 +00005078- Issue #1096: Prevent a segfault from getting the repr of a very
5079 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005080
Brett Cannon1e534b52007-09-07 04:18:30 +00005081- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005082 PyObject_Call() never calling back out to Python code to trigger
5083 recursion depth updates/checks. Required the creation of a static
5084 RuntimeError instance in case normalizing an exception put the
5085 recursion check value past its limit. Fixes crashers
5086 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005087
Georg Brandl3ee81df2008-05-17 18:14:43 +00005088- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005101- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005102 __*__ attributes. (Some already existed, e.g., __doc__ and
5103 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005104
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005105- Add -3 option to the interpreter to warn about features that are
5106 deprecated and will be changed/removed in Python 3.0.
5107
Georg Brandl2134e752007-05-21 20:34:16 +00005108- Patch #1686487: you can now pass any mapping after '**' in function
5109 calls.
5110
Collin Winter62903052007-05-18 23:11:24 +00005111- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005112 "except E as target:". This is to provide forwards compatibility
5113 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005114
Brett Cannon229cee22007-05-05 01:34:02 +00005115- Deprecate BaseException.message as per PEP 352.
5116
Georg Brandl3ee81df2008-05-17 18:14:43 +00005117- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005118 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005119
Vinay Sajip8549ce32007-05-06 17:53:37 +00005120- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005121 setting a plain string, ie don't expand to single letter identifiers.
5122
Raymond Hettinger13936692007-04-11 18:40:58 +00005123- Request #1191699: Slices can now be pickled.
5124
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005125- Request #1193128: str.translate() now allows a None argument for
5126 translations that only remove characters without re-mapping the
5127 remaining characters.
5128
Georg Brandl5cb76c12007-03-21 09:00:39 +00005129- Patch #1682205: a TypeError while unpacking an iterable is no longer
5130 masked by a generic one with the message "unpack non-sequence".
5131
Neal Norwitzaa754b72007-03-21 06:39:48 +00005132- Remove unused file Python/fmod.c.
5133
Guido van Rossum143b5642007-03-23 04:58:42 +00005134- Bug #1683368: The object.__init__() and object.__new__() methods are
5135 now stricter in rejecting excess arguments. The only time when
5136 either allows excess arguments is when it is not overridden and the
5137 other one is. For backwards compatibility, when both are
5138 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005139 warning later). Also, type.__init__() insists on the same signature
5140 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005141
Georg Brandl3ee81df2008-05-17 18:14:43 +00005142- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5143 object to complex using its __complex__() method before falling back
5144 to the __float__() method. Therefore, the functions in the cmath
5145 module now can operate on objects that define a __complex__()
5146 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005147
Georg Brandl3ee81df2008-05-17 18:14:43 +00005148- Patch #1623563: allow __class__ assignment for classes with
5149 __slots__. The old and the new class are still required to have the
5150 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005151

5156 ``object.__reduce_ex__()`` is called with an object that is faking
5157 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005158
Georg Brandl3ee81df2008-05-17 18:14:43 +00005159- Patch #1680015: Don't modify __slots__ tuple if it contains an

5163
Georg Brandl7b9c5552007-03-12 14:30:05 +00005164- Bug #1678647: write a newline after printing an exception in any
5165 case, even when converting the value to a string failed.
5166
Georg Brandl871f1bc2007-03-12 13:17:36 +00005167- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005168 its argument, if it exists. If not, it will work like before. This
5169 allows customizing the output of dir() in the presence of a
5170 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00005172- Patch #922167: Python no longer segfaults when faced with infinitely
5173 self-recursive reload() calls (as reported by bug #742342).
5174
Georg Brandl3ee81df2008-05-17 18:14:43 +00005175- Patch #1675981: remove unreachable code from ``type.__new__()``
5176 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005178- Patch #1491866: change the complex() constructor to allow
5179 parthensized forms. This means complex(repr(x)) now works instead of
5180 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005181
Georg Brandlaa2321b2007-03-07 00:40:28 +00005182- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005183 makes the filenames the warning module prints much more sensible
5184 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005185
Georg Brandl49aafc92007-03-07 00:34:46 +00005186- Variant of patch #697613: don't exit the interpreter on a SystemExit
5187 exception if the -i command line option or PYTHONINSPECT environment

5195 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005196
Georg Brandl0fca97a2007-03-05 22:28:08 +00005197- Patch #1674228: when assigning a slice (old-style), check for the
5198 sq_ass_slice instead of the sq_slice slot.
5199
Georg Brandl3ee81df2008-05-17 18:14:43 +00005200- When printing an unraisable error, don't print exceptions. before
5201 the name. This duplicates the behavior whening normally printing
5202 exceptions.

5827 TestCase and TestSuite subclasses (not instances) are no longer
5828 accepted in TestSuite.addTest(). This should cause no

5830 -- the failure just occurred later, with a more cumbersome
5831 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006112- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6113 with RFC 3207 and forgets any knowledge obtained from the server not
6114 obtained from the TLS negotiation itself. Patch contributed by Bill
6115 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006116
Georg Brandl3ee81df2008-05-17 18:14:43 +00006117- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006118 that the SMTP.starttls() caller no longer needs to call ehlo()
6119 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006120 does not claim to support starttls. Adds the
6121 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

6202 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6203 silently miscode subclasses of those types. Now, it raises a
6204 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006205

Georg Brandl3ee81df2008-05-17 18:14:43 +00006220 time so that opening a database previously created with the DB_DUP
6221 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6222 opens. Specifically: dictionary assignment to a DB object will
6223 replace all values for a given key when the database allows
6224 duplicate values. DB users should use DB.put(k, v) when they want
6225 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006226

6232 characters with ASCII value less than 32. Also, it correctly quotes
6233 dots only if they occur on a single line, as opposed to the previous
6234 behavior of quoting dots if they are the second character of any
6235 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006236

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00006504- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00006505 periodic threadstate and signal checking in tight loops. By
6506 default, this option is turned-off. It should only be enabled in
6507 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00006564
Georg Brandl3ee81df2008-05-17 18:14:43 +00006565- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6566 to ``PyTuple_SetItem``, it can be used to populate a brand new

6579
Georg Brandl3ee81df2008-05-17 18:14:43 +00006580- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6581 of w# format code incorrectly truncated the length to an int, even
6582 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6583 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006584
Georg Brandl3ee81df2008-05-17 18:14:43 +00006585- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6607 outside of pystate.c and should not be necessary.
6608
Georg Brandl3ee81df2008-05-17 18:14:43 +00006609- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6610 absolute imports. In earlier versions they might have used relative
6611 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006612
Georg Brandl3ee81df2008-05-17 18:14:43 +00006613- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6614 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006615
Georg Brandl3ee81df2008-05-17 18:14:43 +00006616- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

6626 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006627

Georg Brandl3ee81df2008-05-17 18:14:43 +00006641- Removed the macfs module. It had been deprecated since Python 2.5.
6642 This lead to the deprecation of macostools.touched() as it relied
6643 solely on macfs and was a no-op under OS X.
