230 This prevents user-created self-referencing ordered dictionaries from
231 becoming permanently uncollectable GC garbage. The downside is that
232 removing __del__ means that the internal doubly-linked list has to wait for
233 GC collection rather than freeing memory immediately when the refcnt drops
234 to zero.
235
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000236- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

239
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000240- Issue #9792: In case of connection failure, socket.create_connection()

242 to fetch the original errno, or to filter timeout errors. Now the
243 original error is re-raised.
244
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000245- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
246 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
247 be updated back after the system call. Original patch by Brian Brazil.
248
Antoine Pitroudca9de92010-09-04 17:52:26 +0000249- Issue #1100562: Fix deep-copying of objects derived from the list and
250 dict types. Patch by Michele Orrù and Björn Lindqvist.

253 ConfigParser.write.
254
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000255- Issue #808164: Fixed socket.close to avoid references to globals, to
256 avoid issues when socket.close is called from a __del__ method.
257
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000258- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

263 falling into recursion.
264
R. David Murray7c4bf552010-08-25 01:45:57 +0000265- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
266 character years even if the message contains RFC822 two character years.
267
Daniel Stutzbach91287322010-08-24 21:09:30 +0000268- Issue #8750: Fixed MutableSet's methods to correctly handle
269 reflexive operations, namely x -= x and x ^= x.
270
Victor Stinnercaafd772010-09-08 10:51:01 +0000271- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

283 ignored by the buffered IO layer anymore.
284
Benjamin Peterson52c36052010-08-21 03:03:22 +0000285- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
286 are not held onto after they are deleted elsewhere.
287
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000288- Issue #9626: the view methods for collections.OrderedDict() were returning
289 the unordered versions inherited from dict. Those methods are now

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000692- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
693 start byte and the continuation byte(s) are now considered invalid, instead
694 of the number of bytes specified by the start byte.
695 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
696 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
697 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

708 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000904- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
905 operation raises multiple signals and more than one of those signals is
906 trapped, the specification determines the order in which the signals should be

1095 code. If a derived class does not currently implement __format__ but later
1096 adds its own __format__, it would most likely break user code that had
1097 supplied a format string. This will be changed to a DeprecationWaring in

Georg Brandlfee0f442010-05-22 21:26:21 +00001148- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1149 InvalidOperation instead of returning False. (Comparisons involving a quiet
1150 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1151 signaling NaNs remain unhashable.

1155 returned an arbitrary result based on the relative ordering of id(float) and
1156 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001158- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001159 argument `-` which tells it to read files to compile from stdin. Each line is
1160 read on demand and the named file is compiled immediately. (Original patch by
1161 Piotr Ożarowski).

1171 Fractions instance now raise TypeError instead of returning True/False. This
1172 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1173 <=> complex, and complex <=> complex comparisons.

1273 integer format code, struct.pack first attempts to convert the non-integer

1276
Georg Brandlba83f822010-03-14 09:50:54 +00001277- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1278 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00001280 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1281 inconsistent: __int__ was used for some integer codes but not for others, and
1282 the set of integer codes for which it was used differed between native packing
1283 and standard packing.)

1588 position to the given argument, which goes against the tradition of

1592 class used to represent files stored inside an archive. The new
1593 implementation is significantly faster and can be wrapped in a

1691
Mark Dickinson1b34d252010-01-01 17:27:30 +00001692- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001693 DeprecationWarning when passed a float argument where an integer was expected.
1694 These functions and methods now raise TypeError instead. The majority of the
1695 effects of this change are in the extension modules, but some core functions
1696 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1697 and many unicode/str methods.

1712 least on IEEE 754 platforms), and in particular does not depend on the
1713 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001862- Issue #3382: 'F' formatting for float and complex now convert the result to
1863 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1864 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001865
Georg Brandlba83f822010-03-14 09:50:54 +00001866- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1867 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001868
Georg Brandlba83f822010-03-14 09:50:54 +00001869- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1870 1e-100 used to raise OverflowError, but now gives the requested 120
1871 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001879
Georg Brandlba83f822010-03-14 09:50:54 +00001880- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1881 decimal string that's guaranteed to round back to x under correct rounding
1882 (with round-half-to-even rounding mode). Previously it gave a string based on
1883 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1884 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1885 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001886
Georg Brandlba83f822010-03-14 09:50:54 +00001887- Issue #7117: On almost all platforms: float-to-string and string-to-float
1888 conversions within Python are now correctly rounded. Places these conversions
1889 occur include: str for floats and complex numbers; the float and complex
1890 constructors; old-style and new-style numeric formatting; serialization and
1891 deserialization of floats and complex numbers using marshal, pickle and json;
1892 parsing of float and imaginary literals in Python code; Decimal-to-float
1893 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001894
Georg Brandlba83f822010-03-14 09:50:54 +00001895 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1896 providing correctly-rounded strtod and dtoa C functions. This code is
1897 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1898 the C compiler. There may be a small number of platforms on which correct
1899 operation of this code cannot be guaranteed, so the code is not used: notably,
1900 this applies to platforms where the C double format is not IEEE 754 binary64,
1901 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1902 and Python's configure script is unable to determine how to change the FPU
1903 precision. On these platforms conversions use the platform strtod and dtoa,
1904 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001905
Georg Brandlba83f822010-03-14 09:50:54 +00001906- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1907 uses the correctly-rounded string <-> float conversions described above (when
1908 available), and so produces correctly rounded results that will display nicely
1909 under the float repr. There are two related small changes: (1) round now
1910 accepts any class with an ``__index__()`` method for its second argument (but
1911 no longer accepts floats for the second argument), and (2) an excessively
1912 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1913 raises an exception.

1916
Georg Brandlba83f822010-03-14 09:50:54 +00001917- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00002206- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2207 existing .py counterpart, override the co_filename attributes of all code
2208 objects if the original filename is obsolete (which can happen if the file has

3693
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003694- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3695
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003696- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3697 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3698 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3699 ``printf`` function, whereas PyString_FromFormat has an independent
3700 implementation and uses "%zd" on all platforms for size_t values.
3701 This makes a difference on win64, where ``printf`` needs "%Id" to display
3702 64bit values.
3703
Benjamin Peterson97179b02008-09-09 20:55:01 +00003704- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3705 error.
3706
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003707- Issue #3777: long() applied to a float object now always return a long
3708 object; previously an int would be returned for small values. the __long__
3709 method is allowed to return either an int or a long, but the behaviour of
3710 float objects should not change to respect backward compatibility.
3711
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003712- Issue #3751: str.rpartition would perform a left-partition when called with
3713 a unicode argument.
3714
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003715- Issue #3683: Fix compilation when --without-threads is given.
3716
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003717- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003718 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003719 was correctly parsed but parsing of subsequent arguments failed.
3720
Vinay Sajip35e3b032008-09-01 14:33:59 +00003721- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003722 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3723 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3724 when given a tuple of classes as second argument, were looking up
3725 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3726 type object.
3727
Neal Norwitz18aa3882008-08-24 05:04:52 +00003728- Fix crashes on memory allocation failure found with failmalloc.
3729
3730- Fix memory leaks found with valgrind and update suppressions file.
3731
3732- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3733
3734- Fix problem using wrong name in decimal module reported by pychecker.
3735
Christian Heimes7d4c3172008-08-22 19:47:25 +00003736- Silenced another compiler warning about a used but not defined
3737 function 'stringlib_contains_obj'.
3738
Benjamin Peterson712ee922008-08-24 18:10:20 +00003739- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3740 ``__delslice__``.
3741
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003742- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3743 library targets in the Makefile.
3744
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003745- Issue #1204: The configure script now tests for additional libraries
3746 that may be required when linking against readline. This fixes issues
3747 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
3748
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00003749C-API

3756
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00003757- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
3758 stack usage in the case of deeply nested objects.
3759
Guido van Rossume3c4fd92008-09-10 14:27:00 +00003760- Issue #3629: Fix sre "bytecode" validator for an end case.
3761
Martin v. Löwis24329ba2008-09-10 13:38:12 +00003762- Issue #3811: The Unicode database was updated to 5.1.
3763
Nick Coghland2e09382008-09-11 12:11:06 +00003764- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
3765 silent misbehaviour when a single instance is nested in multiple
3766 with statements, or when the methods are invoked in the wrong order.
3767
Vinay Sajip844f7412008-09-09 13:42:08 +00003768- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
3769
Nick Coghland2e09382008-09-11 12:11:06 +00003770- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003771 return a list or None rather than a custom object.
3772
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003773- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3774
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003775- Issue #3535: zipfile couldn't read some zip files larger than 2GB.
3776
3777- Issue #3776: Deprecate the bsddb package for removal in 3.0.
Brett Cannon32476fc2008-09-05 18:33:51 +00003778
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +00003779- Issue #3762: platform.architecture() fails if python is lanched via
3780 its symbolic link.
3781
Vinay Sajip65d66e12008-09-04 07:31:21 +00003782- Issue #3772: Fixed regression problem in StreamHandler.emit().

Facundo Batistac585df92008-09-03 22:35:50 +00003785 to the urlparse one. Added a PendingDeprecationWarning in the old
3786 module, it will be deprecated in the future.
3787
Marc-André Lemburgb339b2a2008-09-03 11:13:56 +00003788- Issue #2562: Fix distutils PKG-INFO writing logic to allow having

3794 path to the Python binary.
3795
Georg Brandl222e2082010-08-01 22:27:39 +00003796- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00003797 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3798 for catch_warnings() also led to an improvement in the raising of a
3799 DeprecationWarning related to warnings.warn_explicit().
3800
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003801- The deprecation warnings for the old camelCase threading API were removed.
3802
Vinay Sajip35e3b032008-09-01 14:33:59 +00003803- logging: fixed lack of use of encoding attribute specified on a stream.
3804
Christian Heimesa27a62e2008-08-22 19:55:54 +00003805- Silenced a trivial compiler warning in the sqlite module.
3806
Christian Heimes1cc69632008-08-22 20:10:27 +00003807- Fixed two format strings in the _collections module.
3808
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003809- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
3810 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00003811
Gregory P. Smithd7122032008-09-02 05:36:11 +00003812- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
3813 non-integer floating point number.
3814
Vinay Sajip65d66e12008-09-04 07:31:21 +00003815- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

3820
Jesse Noller438195f2009-01-18 21:04:36 +00003821- Issue #4301: Patch the logging module to add processName support, remove
3822 _check_logger_class from multiprocessing.
3823
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003824- Issue #2975: When compiling several extension modules with Visual Studio 2008
3825 from the same python interpreter, some environment variables would grow
3826 without limit.
3827
Benjamin Peterson37346b22008-08-23 20:27:43 +00003828- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3829 exploitation of poor argument checking.
3830
Gerhard Häringef2276b2008-09-12 13:54:06 +00003831- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3832
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003833- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3834 remaining ones have "pysqlite_" prefix.
3835
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003836- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves
3837 concurrent access to the same SQLite database from multiple
3838 threads/processes.

3842
Nick Coghland2e09382008-09-11 12:11:06 +00003843- Issue #3781: Add test.test_support.check_warnings() as a convenience
3844 wrapper for warnings.catch_warnings() that makes it easier to check
3845 that expected warning messages are being reported.
3846
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003847- Issue #3796: Some tests functions were not enabled in test_float.
3848
3849- Issue #3768: Move test_py3kwarn over to the new API for catch_warnings().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003865What's New in Python 2.6 beta 3?
3866================================
3867
Barry Warsaw07a4a382008-08-21 01:15:08 +00003868*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003869
3870Core and Builtins
3871-----------------
3872
Guido van Rossumf8402962008-08-20 15:01:50 +00003873- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3874 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3875 extensions do not automatically benefit from the class attribute
3876 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3877 to their tp_flags field if they care. This is a backwards
3878 compatibility feature; in 3.0, all types will use the cache by
3879 default.
3880
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003881- Keyword arguments can now follow starred arguments. (``f(a, *args,
3882 keyword=23)`` is now valid syntax.)
3883
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003884- ctypes function pointers that are COM methods have a boolean True
3885 value again.
3886
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003887- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3888 by denying s# to parse objects that have a releasebuffer procedure,
3889 and introducing s*.
3890
Georg Brandl1e13ea92008-08-11 09:07:59 +00003891- Issue #3537: Fix an assertion failure when an empty but presized dict
3892 object was stored in the freelist.
3893
Mark Dickinsonb6467572008-08-04 21:30:09 +00003894- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3895 ValueError consistently across platforms.
3896
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003897- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3898 (64bit Unix, for example), unichr() would truncate its argument and return
3899 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3900
Neal Norwitze7d8be82008-07-31 17:17:14 +00003901- Apply security patches from Apple.
3902
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003903- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3904 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3905
Antoine Pitrou92f82162008-07-25 22:22:08 +00003906- Issue #1819: function calls with several named parameters are now on
3907 average 35% faster (as measured by pybench).
3908
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003909- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3910 the python debugger steps into a class statement: the free variables (local
3911 variables defined in an outer scope) would be deleted from the outer scope.
3912
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003913- Issue #2620: Overflow checking when allocating or reallocating memory
3914 was not always being done properly in some python types and extension
3915 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3916 all been updated to perform better checks and places in the code that
3917 would previously leak memory on the error path when such an allocation
3918 failed have been fixed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003920Library
3921-------
3922
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003923- Issue #3612: Added some missing basic types in ctypes.wintypes.
3924
Benjamin Petersone977ad42008-08-20 01:42:01 +00003925- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3926 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3927
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003928- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3929 version reported by these tools does not necessarily follow the python
3930 version numbering scheme, so the module is less strict when parsing it.
3931
Nick Coghlanf70385a2008-08-18 12:42:46 +00003932- Issue #2235: Added Py3k warnings for types which will become unhashable
3933 under the stricter __hash__ inheritance rules in 3.0. Several types
3934 which did not meet the rules for hash invariants and were already
3935 unhashable in 3.0 have now been explicitly flagged as unhashable in
3936 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3937 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3938
Brett Cannon88f801d2008-08-18 00:46:22 +00003939- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3940 imported into the module but exposed as part of the module's API.
3941
Brett Cannon7b96f072008-08-18 00:41:11 +00003942- Remove an unneeded import of abc.ABCMeta from 'inspect'.

3947
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003948- Issue #3575: Incremental decoder's decode function now takes bytearray
3949 by using 's*' instead of 't#'.
3950
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003951- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003952 fails unicode conversion on 2nd parameter. (windows only)
3953
Georg Brandl222e2082010-08-01 22:27:39 +00003954- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003955 in a redirect.
3956
Brett Cannonabe423e2008-08-16 21:47:07 +00003957- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003958 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003959
Facundo Batistaeb90b782008-08-16 14:44:07 +00003960- Issue #2776: fixed small issue when handling an URL with double slash
3961 after a 302 response in the case of not going through a proxy.
3962
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003963- Issue #2676: in the email package, content-type parsing was hanging on
3964 pathological input because of quadratic or exponential behaviour of a
3965 regular expression.
3966
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003967- Issue #3476: binary buffered reading through the new "io" library is now
3968 thread-safe.
3969
Brett Cannonbf3157b2008-08-14 05:00:03 +00003970- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3971 since mimetools itself is deprecated. Because modules are cached, all
3972 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3973
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003974- Issue #3134: shutil referenced undefined WindowsError symbol.
3975
Robert Schuppenies14646332008-08-10 11:01:53 +00003976- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3977 menu entries were not deleted.

Antoine Pitroude781a42008-08-09 12:43:23 +00004008 asking for a specific length. This problem only affected files opened

4052
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004053- Issue #643841: The language reference now provides more detailed
4054 coverage of the lookup process for special methods. The disclaimers
4055 regarding lack of coverage of new-style classes have also been

4061
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004062*Release date: 17-Jul-2008*

4065-----------------
4066
Georg Brandl3e483f62008-07-16 22:57:41 +00004067- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4068 its methods now allow for items objects that can be converted to
4069 an integer using operator.index().
4070
Mark Dickinson64b7e502008-07-16 09:40:03 +00004071- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4072 produced a ValueError instead of giving the correct float.
4073
Eric Smitha5fa5a22008-07-16 00:11:49 +00004074- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4075 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4076
Mark Dickinson7103aa42008-07-15 19:08:33 +00004077- Issue #3008: the float type has a new instance method 'float.hex'
4078 and a new class method 'float.fromhex' to convert floating-point
4079 numbers to and from hexadecimal strings, respectively.
4080
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004081- Issue #2235: __hash__ is once again inherited by default. To allow
4082 collections.Hashable to remain meaningful in the presence of the
4083 default hash implementation (object.__hash__), it is now possible
4084 to explicit block inheritance of hash by setting __hash__=None at
4085 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4086 level.
4087
Nick Coghlanb028f502008-07-13 14:52:36 +00004088- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4089 the parent module cannot be found while performing an absolute import.
4090 This means that an incorrectly defined __package__ attribute will
4091 now only prevent relative imports in that module rather than causing
4092 all imports from that module to fail.
4093
Nick Coghlan14ff9942008-07-08 14:21:42 +00004094- Issue #2517: Allow unicode messages in Exceptions again by correctly

4103 threading.local: the first member set by a thread could be saved in
4104 another thread's dictionary.
4105
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004106- Issue #3004: Minor change to slice.indices(): the start and stop
4107 arguments are now treated identically, making the behaviour easier
4108 to describe and understand. For example, slice(None, -10,
4109 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4110 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4111 10, -1).
4112
Georg Brandl278fc502008-07-19 12:46:12 +00004113- Issue #3219: Calling a function with repeated keyword arguments,
4114 f(a=2, a=23), would not cause a syntax error. This was a regression
4115 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004116
Georg Brandl278fc502008-07-19 12:46:12 +00004117- Issue #2862: Make int and float freelist management consistent with
4118 other freelists. Changes their CompactFreeList apis into

4125 api functions without holding the GIL, which could lead to a fatal
4126 error when they failed.
4127
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004128- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004153- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4154 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004155 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004156 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004172- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4545 an extension. This was added for compatibility with Apple's build
4546 of Python.
4547
4548- The bundled OSX-specific copy of libbffi is now in sync with the version
4549 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
4550
Georg Brandl25c34082008-08-18 23:09:49 +00004551- The threading module gained aliases for names that will be removed in the
4552 3.x series.

4560
Brett Cannonb61d8012008-05-11 23:39:04 +00004561- ``Lib/lib-old`` is now added to sys.path.
4562
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004563- On MacOS X it is now possible to install the framework in 64-bit
4564 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004565 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004566
4567 This is controlled by the configure argument ``--with-universal-archs``:
4568
4569 - ``--with-universal-archs=all``: install 4-way universal
4570
4571 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4572
4573 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4574
4575 This option should be used in combination with ``--enable-universalsdk=``.
4576
4577 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00004586
4587- The PyString functions have been renamed to PyBytes. A batch of
4588 defines were added so that the linker still sees the original
4589 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004627- Issue #1631171: Re-implement the 'warnings' module in C (the
4628 original Python code has been kept as backup). This will allow for
4629 using the 'warning's machinery in such places as the parser where
4630 use of pure Python code is not possible. Both the ``showarning()``
4631 and ``formatwarning()`` gain an optional 'line' argument which is
4632 not called by default for backwards-compatibility reasons. Setting
4633 ``warnings.showwarning()`` to an implementation that lacks support
4634 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004659- The getpass module has been improved on Unix. It now uses /dev/tty
4660 by default and uses stderr instead of stdout. A GetPassWarning is
4661 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004676- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004677 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004697- Issue #2550: The approach used by client/server code for obtaining
4698 ports to listen on in network-oriented tests has been refined in an
4699 effort to facilitate running multiple instances of the entire
4700 regression test suite in parallel without issue.
4701 test_support.bind_port() has been fixed such that it will always
4702 return a unique port -- which wasn't always the case with the
4703 previous implementation, especially if socket options had been set
4704 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4705 new implementation of bind_port() will actually raise an exception
4706 if it is passed an AF_INET/SOCK_STREAM socket with either the
4707 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4708 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4709 the socket it's been passed. This currently only applies to
4710 Windows. This option prevents any other sockets from binding to the
4711 host/port we've bound to, thus removing the possibility of the
4712 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4713 when a second SOCK_STREAM socket binds and accepts to a host/port
4714 that's already been bound by another socket. The optional preferred
4715 port parameter to bind_port() has been removed. Under no
4716 circumstances should tests be hard coding ports!
4717
4718 test_support.find_unused_port() has also been introduced, which will
4719 pass a temporary socket object to bind_port() in order to obtain an
4720 unused port. The temporary socket object is then closed and
4721 deleted, and the port is returned. This method should only be used
4722 for obtaining an unused port in order to pass to an external program
4723 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4724 a parameter to a server-oriented class that doesn't give you direct
4725 access to the underlying socket used.
4726
4727 Finally, test_support.HOST has been introduced, which should be used
4728 for the host argument of any relevant socket calls (i.e. bind and
4729 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004730
4731 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004732 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004733 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4734 test_asynchat and test_socket_ssl.
4735
Georg Brandl3ee81df2008-05-17 18:14:43 +00004736 It is now possible for multiple instances of the regression test
4737 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005016- Added the future_builtins module, which contains hex() and oct().
5017 These are the PEP 3127 version of these functions, designed to be
5018 compatible with the hex() and oct() builtins from Python 3.0. They
5019 differ slightly in their output formats from the existing, unchanged
5020 Python 2.6 builtins. The expected usage of the future_builtins
5021 module is:
5022 from future_builtins import hex, oct
5023
Eric Smith7ef40bf2008-02-20 23:34:22 +00005024- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5025 exponents for exponents with absolute value < 100. Follows C99
5026 standard. This is a change on Windows, which would use 3 digits.
5027 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5028 so that any alterations it does to the resulting string will be
5029 available in stringlib/formatter.h (for float.__format__).
5030
Eric Smith5a3c1352008-02-19 13:21:56 +00005031- Implemented PEP 3101, Advanced String Formatting. This adds a new
5032 builtin format(); a format() method for str and unicode; a
5033 __format__() method to object, str, unicode, int, long, float, and
5034 datetime; the class string.Formatter; and the C API
5035 PyObject_Format().
5036
Georg Brandl3ee81df2008-05-17 18:14:43 +00005037- Fixed several potential crashes, all caused by specially crafted
5038 __del__ methods exploiting objects in temporarily inconsistent
5039 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005040
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005041- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005042 prevent a possible crash: an Abstract Base Class would try to access
5043 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005044

5049 in order to allow pymalloc to free more arenas. Python may give back
5050 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005051
Georg Brandl3ee81df2008-05-17 18:14:43 +00005052- Issue #2045: Fix an infinite recursion triggered when printing a
5053 subclass of collections.defaultdict, if its default_factory is set
5054 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005055
Christian Heimesf75dbef2008-02-08 00:11:31 +00005056- Fixed a minor memory leak in dictobject.c. The content of the free
5057 list was not freed on interpreter shutdown.
5058
Georg Brandl21e99f42010-03-07 15:23:59 +00005059- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005061
Georg Brandl3ee81df2008-05-17 18:14:43 +00005062- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5063 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005064 to compact the internal free lists of pre-allocted ints and floats.
5065
Georg Brandl3ee81df2008-05-17 18:14:43 +00005066- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5067 calls. Python expected the return type int but the fork familie
5068 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005069
Georg Brandl3ee81df2008-05-17 18:14:43 +00005070- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5071 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005072
Georg Brandl3ee81df2008-05-17 18:14:43 +00005073- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5074 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005075
Georg Brandl3ee81df2008-05-17 18:14:43 +00005076- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5077 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00005079- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5080 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005081
Georg Brandl3ee81df2008-05-17 18:14:43 +00005082- Patch #1473257: generator objects gain a gi_code attribute. This is
5083 the same object as the func_code attribute of the function that
5084 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005085
Georg Brandl3ee81df2008-05-17 18:14:43 +00005086- Issue #1920: "while 0" statements were completely removed by the
5087 compiler, even in the presence of an "else" clause, which is
5088 supposed to be run when the condition is false. Now the compiler
5089 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005090
Guido van Rossumeead05f2008-01-24 18:21:02 +00005091- A few crashers fixed: weakref_in_del.py (issue #1377858);
5092 loosing_dict_ref.py (issue #1303614, test67.py);
5093 borrowed_ref_[34].py (not in tracker).
5094
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005095- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005096 suppressed while an extension is loaded by calling SetErrorMode in
5097 dynload_win.c. The error is still reported properly.
5098
Georg Brandl3ee81df2008-05-17 18:14:43 +00005099- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005100 several extension methods and modules do not work without unicode
5101 support.
5102
Georg Brandl26543b12008-01-21 18:36:51 +00005103- Issue #1882: when compiling code from a string, encoding cookies in the
5104 second line of code were not always recognized correctly.
5105
Georg Brandl14404b62008-01-19 19:27:05 +00005106- Issue #1679: "0x" was taken as a valid integer literal.
5107
Georg Brandl6caad7d2008-01-26 14:19:22 +00005108- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005109 added.
5110
Christian Heimesc94e2b52008-01-14 04:13:37 +00005111- sys.float_info / PyFloat_GetInfo: The floating point information
5112 object was converted from a dict to a specialized structseq object.
5113
Georg Brandl3ee81df2008-05-17 18:14:43 +00005114- Patch #1816: Added sys.flags structseq. It exposes the status of
5115 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005116
Georg Brandl3ee81df2008-05-17 18:14:43 +00005117- Objects/structseq.c: Implemented new structseq representation. The
5118 patch makes structseqs (e.g. the return value of os.stat) more
5119 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005120
Georg Brandl3ee81df2008-05-17 18:14:43 +00005121- Patch #1700288: added a type attribute cache that caches method
5122 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005123
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005124- Bug #1776: __import__() no longer accepts filenames on any platform.
5125 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005126
Georg Brandlaed6c662008-01-07 17:25:53 +00005127- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5128
Georg Brandl3ee81df2008-05-17 18:14:43 +00005129- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5130 envvar and sys.dont_write_bytecode attribute. All these can be set
5131 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005132
Georg Brandl3ee81df2008-05-17 18:14:43 +00005133- Improve some exception messages when Windows fails to load an
5134 extension module. Now we get for example '%1 is not a valid Win32
5135 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005136
Georg Brandl3ee81df2008-05-17 18:14:43 +00005137- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005139- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5140 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005141
Christian Heimes0a8143f2007-12-18 23:22:54 +00005142- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005143 and INF. float("nan"), float("inf") and float("-inf") now work on
5144 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005145
Georg Brandl3ee81df2008-05-17 18:14:43 +00005146- Compiler now generates simpler and faster code for dictionary
5147 literals. The oparg for BUILD_MAP now indicates an estimated
5148 dictionary size. There is a new opcode, STORE_MAP, for adding
5149 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005178- Patch #1739468: Directories and zipfiles containing a __main__.py
5179 file can now be directly executed by passing their name to the
5180 interpreter. The directory/zipfile is automatically inserted as the
5181 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005182
Georg Brandl3ee81df2008-05-17 18:14:43 +00005183- Issue #1265: Fix a problem with sys.settrace, if the tracing
5184 function uses a generator expression when at the same time the
5185 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005186
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005187- sets and frozensets now have an isdisjoint() method.
5188
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005189- optimize the performance of builtin.sum().
5190
Neal Norwitz44f326e2007-10-05 05:29:17 +00005191- Fix warnings found by the new version of the Coverity checker.
5192
Georg Brandl21e99f42010-03-07 15:23:59 +00005193- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005194 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5195 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005196
Georg Brandl3ee81df2008-05-17 18:14:43 +00005197- Issue #1686386: Tuple's tp_repr did not take into account the
5198 possibility of having a self-referential tuple, which is possible
5199 from C code. Nor did object's tp_str consider that a type's tp_str
5200 could do something that could lead to an inifinite recursion.
5201 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5202 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005203
Georg Brandl3ee81df2008-05-17 18:14:43 +00005204- Issue #1164: It was possible to trigger deadlock when using the
5205 'print' statement to write to a file since the GIL was not released
5206 as needed. Now PyObject_Print() does the right thing along with
5207 various tp_print implementations of the built-in types and those in
5208 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005209
Georg Brandl3ee81df2008-05-17 18:14:43 +00005210- Issue #1147: Exceptions were directly allowing string exceptions in
5211 their throw() method even though string exceptions no longer
5212 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005213
Georg Brandl3ee81df2008-05-17 18:14:43 +00005214- Issue #1096: Prevent a segfault from getting the repr of a very
5215 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005216
Brett Cannon1e534b52007-09-07 04:18:30 +00005217- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005218 PyObject_Call() never calling back out to Python code to trigger
5219 recursion depth updates/checks. Required the creation of a static
5220 RuntimeError instance in case normalizing an exception put the
5221 recursion check value past its limit. Fixes crashers
5222 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005223
Georg Brandl3ee81df2008-05-17 18:14:43 +00005224- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005237- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005238 __*__ attributes. (Some already existed, e.g., __doc__ and
5239 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005240
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005241- Add -3 option to the interpreter to warn about features that are
5242 deprecated and will be changed/removed in Python 3.0.
5243
Georg Brandl2134e752007-05-21 20:34:16 +00005244- Patch #1686487: you can now pass any mapping after '**' in function
5245 calls.
5246
Collin Winter62903052007-05-18 23:11:24 +00005247- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005248 "except E as target:". This is to provide forwards compatibility
5249 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005250
Brett Cannon229cee22007-05-05 01:34:02 +00005251- Deprecate BaseException.message as per PEP 352.
5252
Georg Brandl3ee81df2008-05-17 18:14:43 +00005253- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005254 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005255
Vinay Sajip8549ce32007-05-06 17:53:37 +00005256- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005257 setting a plain string, ie don't expand to single letter identifiers.
5258
Raymond Hettinger13936692007-04-11 18:40:58 +00005259- Request #1191699: Slices can now be pickled.
5260
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005261- Request #1193128: str.translate() now allows a None argument for
5262 translations that only remove characters without re-mapping the
5263 remaining characters.
5264
Georg Brandl5cb76c12007-03-21 09:00:39 +00005265- Patch #1682205: a TypeError while unpacking an iterable is no longer
5266 masked by a generic one with the message "unpack non-sequence".
5267
Neal Norwitzaa754b72007-03-21 06:39:48 +00005268- Remove unused file Python/fmod.c.
5269
Guido van Rossum143b5642007-03-23 04:58:42 +00005270- Bug #1683368: The object.__init__() and object.__new__() methods are
5271 now stricter in rejecting excess arguments. The only time when
5272 either allows excess arguments is when it is not overridden and the
5273 other one is. For backwards compatibility, when both are
5274 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005275 warning later). Also, type.__init__() insists on the same signature
5276 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005277
Georg Brandl3ee81df2008-05-17 18:14:43 +00005278- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5279 object to complex using its __complex__() method before falling back
5280 to the __float__() method. Therefore, the functions in the cmath
5281 module now can operate on objects that define a __complex__()
5282 method.

Georg Brandl871f1bc2007-03-12 13:17:36 +00005303- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005304 its argument, if it exists. If not, it will work like before. This
5305 allows customizing the output of dir() in the presence of a
5306 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00005318- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl4e933132006-09-06 20:05:58 +00005421- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005830 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005871 AttributeError instead of an IOError when the server's response

5963 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006356 time so that opening a database previously created with the DB_DUP
6357 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6358 opens. Specifically: dictionary assignment to a DB object will
6359 replace all values for a given key when the database allows
6360 duplicate values. DB users should use DB.put(k, v) when they want
6361 to store duplicates; not DB[k] = v.

6368 characters with ASCII value less than 32. Also, it correctly quotes
6369 dots only if they occur on a single line, as opposed to the previous
6370 behavior of quoting dots if they are the second character of any
6371 line.
