237 This prevents user-created self-referencing ordered dictionaries from
238 becoming permanently uncollectable GC garbage. The downside is that
239 removing __del__ means that the internal doubly-linked list has to wait for
240 GC collection rather than freeing memory immediately when the refcnt drops
241 to zero.
242

Raymond Hettingerffd2a422010-09-10 10:47:22 +0000245 value.
246
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000247- Issue #9792: In case of connection failure, socket.create_connection()
248 would swallow the exception and raise a new one, making it impossible
249 to fetch the original errno, or to filter timeout errors. Now the
250 original error is re-raised.
251
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000252- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
253 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
254 be updated back after the system call. Original patch by Brian Brazil.
255
Antoine Pitroudca9de92010-09-04 17:52:26 +0000256- Issue #1100562: Fix deep-copying of objects derived from the list and
257 dict types. Patch by Michele Orrù and Björn Lindqvist.
258

260 ConfigParser.write.
261
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000262- Issue #808164: Fixed socket.close to avoid references to globals, to
263 avoid issues when socket.close is called from a __del__ method.
264
Terry Reedyd2d2ae92010-11-11 23:22:19 +0000265- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

267 heuristic. Patch by Terry Reedy and Eli Bendersky

270 falling into recursion.
271
R. David Murray7c4bf552010-08-25 01:45:57 +0000272- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
273 character years even if the message contains RFC822 two character years.
274
Daniel Stutzbach91287322010-08-24 21:09:30 +0000275- Issue #8750: Fixed MutableSet's methods to correctly handle
276 reflexive operations, namely x -= x and x ^= x.
277
Victor Stinnercaafd772010-09-08 10:51:01 +0000278- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing

290 ignored by the buffered IO layer anymore.
291
Benjamin Peterson52c36052010-08-21 03:03:22 +0000292- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
293 are not held onto after they are deleted elsewhere.
294
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000295- Issue #9626: the view methods for collections.OrderedDict() were returning

700 start byte and the continuation byte(s) are now considered invalid, instead
701 of the number of bytes specified by the start byte.
702 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
703 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

715 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000911- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
912 operation raises multiple signals and more than one of those signals is
913 trapped, the specification determines the order in which the signals should be

1104 supplied a format string. This will be changed to a DeprecationWaring in

Georg Brandlfee0f442010-05-22 21:26:21 +00001138- Issue #8257: The Decimal construct now accepts a float instance directly,
1139 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001140
1141 >>> Decimal(1.1)
1142 Decimal('1.100000000000000088817841970012523233890533447265625')
1143

Georg Brandlfee0f442010-05-22 21:26:21 +00001155- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1156 InvalidOperation instead of returning False. (Comparisons involving a quiet
1157 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1158 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001160- Issue #2531: Comparison operations between floats and Decimal instances now
1161 return a result based on the numeric values of the operands; previously they
1162 returned an arbitrary result based on the relative ordering of id(float) and
1163 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001165- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001166 argument `-` which tells it to read files to compile from stdin. Each line is
1167 read on demand and the named file is compiled immediately. (Original patch by
1168 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00001177- Comparisons using one of <, <=, >, >= between a complex instance and a
1178 Fractions instance now raise TypeError instead of returning True/False. This
1179 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1180 <=> complex, and complex <=> complex comparisons.

1280 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00001284- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1285 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00001287 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1288 inconsistent: __int__ was used for some integer codes but not for others, and
1289 the set of integer codes for which it was used differed between native packing
1290 and standard packing.)

Mark Dickinson1b34d252010-01-01 17:27:30 +00001699- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001700 DeprecationWarning when passed a float argument where an integer was expected.
1701 These functions and methods now raise TypeError instead. The majority of the
1702 effects of this change are in the extension modules, but some core functions
1703 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1704 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00001866- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
1867 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00001869- Issue #3382: 'F' formatting for float and complex now convert the result to
1870 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1871 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001872
Georg Brandlba83f822010-03-14 09:50:54 +00001873- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1874 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001875
Georg Brandlba83f822010-03-14 09:50:54 +00001876- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1877 1e-100 used to raise OverflowError, but now gives the requested 120
1878 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001879
Georg Brandlba83f822010-03-14 09:50:54 +00001880- Add Py3k warnings for parameter names in parentheses.

1885 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001886
Georg Brandlba83f822010-03-14 09:50:54 +00001887- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1888 decimal string that's guaranteed to round back to x under correct rounding
1889 (with round-half-to-even rounding mode). Previously it gave a string based on
1890 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1891 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1892 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001893
Georg Brandlba83f822010-03-14 09:50:54 +00001894- Issue #7117: On almost all platforms: float-to-string and string-to-float
1895 conversions within Python are now correctly rounded. Places these conversions
1896 occur include: str for floats and complex numbers; the float and complex
1897 constructors; old-style and new-style numeric formatting; serialization and
1898 deserialization of floats and complex numbers using marshal, pickle and json;
1899 parsing of float and imaginary literals in Python code; Decimal-to-float
1900 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001901
Georg Brandlba83f822010-03-14 09:50:54 +00001902 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1903 providing correctly-rounded strtod and dtoa C functions. This code is
1904 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1905 the C compiler. There may be a small number of platforms on which correct
1906 operation of this code cannot be guaranteed, so the code is not used: notably,
1907 this applies to platforms where the C double format is not IEEE 754 binary64,
1908 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1909 and Python's configure script is unable to determine how to change the FPU
1910 precision. On these platforms conversions use the platform strtod and dtoa,
1911 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001912
Georg Brandlba83f822010-03-14 09:50:54 +00001913- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1914 uses the correctly-rounded string <-> float conversions described above (when
1915 available), and so produces correctly rounded results that will display nicely
1916 under the float repr. There are two related small changes: (1) round now
1917 accepts any class with an ``__index__()`` method for its second argument (but
1918 no longer accepts floats for the second argument), and (2) an excessively
1919 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1920 raises an exception.

1923
Georg Brandlba83f822010-03-14 09:50:54 +00001924- Fix several issues with ``compile()``. The input can now contain Windows and
1925 Mac newlines and is no longer required to end in a newline.

1956 The tables for code points representing numeric values, white spaces or line
1957 breaks are now generated from the official Unicode Character Database files,
1958 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00002067- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2068 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2069 but with at least one decimal point and with a default precision
2070 of 12. Previously, the behavior the same but with a default precision of 6.
2071 This more closely matches ``str()``, and reduces surprises when adding

3700
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003701- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3702
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003703- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3704 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3705 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3706 ``printf`` function, whereas PyString_FromFormat has an independent
3707 implementation and uses "%zd" on all platforms for size_t values.
3708 This makes a difference on win64, where ``printf`` needs "%Id" to display
3709 64bit values.
3710
Benjamin Peterson97179b02008-09-09 20:55:01 +00003711- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3712 error.
3713
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003714- Issue #3777: long() applied to a float object now always return a long
3715 object; previously an int would be returned for small values. the __long__
3716 method is allowed to return either an int or a long, but the behaviour of
3717 float objects should not change to respect backward compatibility.
3718
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003719- Issue #3751: str.rpartition would perform a left-partition when called with
3720 a unicode argument.
3721
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003722- Issue #3683: Fix compilation when --without-threads is given.
3723
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003724- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003725 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003726 was correctly parsed but parsing of subsequent arguments failed.
3727
Vinay Sajip35e3b032008-09-01 14:33:59 +00003728- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003729 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3730 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3731 when given a tuple of classes as second argument, were looking up
3732 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3733 type object.
3734
Neal Norwitz18aa3882008-08-24 05:04:52 +00003735- Fix crashes on memory allocation failure found with failmalloc.
3736
3737- Fix memory leaks found with valgrind and update suppressions file.
3738
3739- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3740
3741- Fix problem using wrong name in decimal module reported by pychecker.
3742
Christian Heimes7d4c3172008-08-22 19:47:25 +00003743- Silenced another compiler warning about a used but not defined
3744 function 'stringlib_contains_obj'.
3745
Benjamin Peterson712ee922008-08-24 18:10:20 +00003746- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3747 ``__delslice__``.
3748
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003749- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3750 library targets in the Makefile.
3751
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003752- Issue #1204: The configure script now tests for additional libraries
3753 that may be required when linking against readline. This fixes issues
3754 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
3755
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00003756C-API

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00003764- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
3765 stack usage in the case of deeply nested objects.
3766

Nick Coghland2e09382008-09-11 12:11:06 +00003777- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003778 return a list or None rather than a custom object.
3779
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003780- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3781
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003782- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003804 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3805 for catch_warnings() also led to an improvement in the raising of a
3806 DeprecationWarning related to warnings.warn_explicit().
3807
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003808- The deprecation warnings for the old camelCase threading API were removed.

3830
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003831- Issue #2975: When compiling several extension modules with Visual Studio 2008
3832 from the same python interpreter, some environment variables would grow
3833 without limit.
3834
Benjamin Peterson37346b22008-08-23 20:27:43 +00003835- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3836 exploitation of poor argument checking.
3837
Gerhard Häringef2276b2008-09-12 13:54:06 +00003838- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

3851 wrapper for warnings.catch_warnings() that makes it easier to check
3852 that expected warning messages are being reported.
3853
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003854- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003872What's New in Python 2.6 beta 3?
3873================================

Barry Warsaw07a4a382008-08-21 01:15:08 +00003875*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003876
3877Core and Builtins
3878-----------------
3879
Guido van Rossumf8402962008-08-20 15:01:50 +00003880- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3881 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3882 extensions do not automatically benefit from the class attribute
3883 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3884 to their tp_flags field if they care. This is a backwards
3885 compatibility feature; in 3.0, all types will use the cache by
3886 default.
3887
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003888- Keyword arguments can now follow starred arguments. (``f(a, *args,
3889 keyword=23)`` is now valid syntax.)
3890
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003891- ctypes function pointers that are COM methods have a boolean True
3892 value again.
3893
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003894- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3895 by denying s# to parse objects that have a releasebuffer procedure,
3896 and introducing s*.
3897
Georg Brandl1e13ea92008-08-11 09:07:59 +00003898- Issue #3537: Fix an assertion failure when an empty but presized dict
3899 object was stored in the freelist.
3900
Mark Dickinsonb6467572008-08-04 21:30:09 +00003901- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3902 ValueError consistently across platforms.
3903
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003904- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3905 (64bit Unix, for example), unichr() would truncate its argument and return
3906 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3907
Neal Norwitze7d8be82008-07-31 17:17:14 +00003908- Apply security patches from Apple.
3909
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003910- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3911 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3912
Antoine Pitrou92f82162008-07-25 22:22:08 +00003913- Issue #1819: function calls with several named parameters are now on
3914 average 35% faster (as measured by pybench).
3915
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003916- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3917 the python debugger steps into a class statement: the free variables (local
3918 variables defined in an outer scope) would be deleted from the outer scope.
3919
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003920- Issue #2620: Overflow checking when allocating or reallocating memory
3921 was not always being done properly in some python types and extension
3922 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3923 all been updated to perform better checks and places in the code that
3924 would previously leak memory on the error path when such an allocation
3925 failed have been fixed.

3928-------
3929
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003930- Issue #3612: Added some missing basic types in ctypes.wintypes.
3931
Benjamin Petersone977ad42008-08-20 01:42:01 +00003932- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3933 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3934
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003935- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3936 version reported by these tools does not necessarily follow the python
3937 version numbering scheme, so the module is less strict when parsing it.
3938
Nick Coghlanf70385a2008-08-18 12:42:46 +00003939- Issue #2235: Added Py3k warnings for types which will become unhashable
3940 under the stricter __hash__ inheritance rules in 3.0. Several types
3941 which did not meet the rules for hash invariants and were already
3942 unhashable in 3.0 have now been explicitly flagged as unhashable in
3943 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3944 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3945
Brett Cannon88f801d2008-08-18 00:46:22 +00003946- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3954
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003955- Issue #3575: Incremental decoder's decode function now takes bytearray
3956 by using 's*' instead of 't#'.
3957
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003958- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003959 fails unicode conversion on 2nd parameter. (windows only)
3960
Georg Brandl222e2082010-08-01 22:27:39 +00003961- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003962 in a redirect.
3963
Brett Cannonabe423e2008-08-16 21:47:07 +00003964- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003965 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003966
Facundo Batistaeb90b782008-08-16 14:44:07 +00003967- Issue #2776: fixed small issue when handling an URL with double slash
3968 after a 302 response in the case of not going through a proxy.
3969
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003970- Issue #2676: in the email package, content-type parsing was hanging on
3971 pathological input because of quadratic or exponential behaviour of a
3972 regular expression.
3973
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003974- Issue #3476: binary buffered reading through the new "io" library is now
3975 thread-safe.
3976
Brett Cannonbf3157b2008-08-14 05:00:03 +00003977- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3978 since mimetools itself is deprecated. Because modules are cached, all
3979 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3980

Antoine Pitroude781a42008-08-09 12:43:23 +00004015 asking for a specific length. This problem only affected files opened

4059
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004060- Issue #643841: The language reference now provides more detailed

4073
Georg Brandl3e483f62008-07-16 22:57:41 +00004074- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4075 its methods now allow for items objects that can be converted to
4076 an integer using operator.index().
4077
Mark Dickinson64b7e502008-07-16 09:40:03 +00004078- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4079 produced a ValueError instead of giving the correct float.
4080
Eric Smitha5fa5a22008-07-16 00:11:49 +00004081- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4082 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4083
Mark Dickinson7103aa42008-07-15 19:08:33 +00004084- Issue #3008: the float type has a new instance method 'float.hex'
4085 and a new class method 'float.fromhex' to convert floating-point
4086 numbers to and from hexadecimal strings, respectively.
4087
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004088- Issue #2235: __hash__ is once again inherited by default. To allow
4089 collections.Hashable to remain meaningful in the presence of the
4090 default hash implementation (object.__hash__), it is now possible
4091 to explicit block inheritance of hash by setting __hash__=None at
4092 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4093 level.
4094
Nick Coghlanb028f502008-07-13 14:52:36 +00004095- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4096 the parent module cannot be found while performing an absolute import.
4097 This means that an incorrectly defined __package__ attribute will
4098 now only prevent relative imports in that module rather than causing
4099 all imports from that module to fail.
4100
Nick Coghlan14ff9942008-07-08 14:21:42 +00004101- Issue #2517: Allow unicode messages in Exceptions again by correctly

4111 another thread's dictionary.
4112
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004113- Issue #3004: Minor change to slice.indices(): the start and stop
4114 arguments are now treated identically, making the behaviour easier
4115 to describe and understand. For example, slice(None, -10,
4116 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4117 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4118 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00004120- Issue #3219: Calling a function with repeated keyword arguments,
4121 f(a=2, a=23), would not cause a syntax error. This was a regression
4122 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004160- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4161 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004162 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004163 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004179- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4548 in Python 3.0.
Benjamin Peterson23681932008-05-12 21:42:13 +00004549
Vinay Sajip9828b7e2008-06-17 11:04:02 +00004550- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004551 environment to control the '-arch' flags that are used to build
4552 an extension. This was added for compatibility with Apple's build
4553 of Python.
4554
4555- The bundled OSX-specific copy of libbffi is now in sync with the version
4556 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
4557
Georg Brandl25c34082008-08-18 23:09:49 +00004558- The threading module gained aliases for names that will be removed in the

4567
Brett Cannonb61d8012008-05-11 23:39:04 +00004568- ``Lib/lib-old`` is now added to sys.path.
4569
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004570- On MacOS X it is now possible to install the framework in 64-bit
4571 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004572 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004573
4574 This is controlled by the configure argument ``--with-universal-archs``:
4575
4576 - ``--with-universal-archs=all``: install 4-way universal
4577
4578 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4579
4580 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4581
4582 This option should be used in combination with ``--enable-universalsdk=``.
4583
4584 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 +00004593
4594- The PyString functions have been renamed to PyBytes. A batch of
4595 defines were added so that the linker still sees the original
4596 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004634- Issue #1631171: Re-implement the 'warnings' module in C (the
4635 original Python code has been kept as backup). This will allow for
4636 using the 'warning's machinery in such places as the parser where
4637 use of pure Python code is not possible. Both the ``showarning()``
4638 and ``formatwarning()`` gain an optional 'line' argument which is
4639 not called by default for backwards-compatibility reasons. Setting
4640 ``warnings.showwarning()`` to an implementation that lacks support
4641 for the ``line`` argument will raise a DeprecationWarning.

4665
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004666- The getpass module has been improved on Unix. It now uses /dev/tty
4667 by default and uses stderr instead of stdout. A GetPassWarning is
4668 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004669

Georg Brandl3ee81df2008-05-17 18:14:43 +00004683- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004684 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004704- Issue #2550: The approach used by client/server code for obtaining
4705 ports to listen on in network-oriented tests has been refined in an
4706 effort to facilitate running multiple instances of the entire
4707 regression test suite in parallel without issue.
4708 test_support.bind_port() has been fixed such that it will always
4709 return a unique port -- which wasn't always the case with the
4710 previous implementation, especially if socket options had been set
4711 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4712 new implementation of bind_port() will actually raise an exception
4713 if it is passed an AF_INET/SOCK_STREAM socket with either the
4714 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4715 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4716 the socket it's been passed. This currently only applies to
4717 Windows. This option prevents any other sockets from binding to the
4718 host/port we've bound to, thus removing the possibility of the
4719 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4720 when a second SOCK_STREAM socket binds and accepts to a host/port
4721 that's already been bound by another socket. The optional preferred
4722 port parameter to bind_port() has been removed. Under no
4723 circumstances should tests be hard coding ports!
4724
4725 test_support.find_unused_port() has also been introduced, which will
4726 pass a temporary socket object to bind_port() in order to obtain an
4727 unused port. The temporary socket object is then closed and
4728 deleted, and the port is returned. This method should only be used
4729 for obtaining an unused port in order to pass to an external program
4730 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4731 a parameter to a server-oriented class that doesn't give you direct
4732 access to the underlying socket used.
4733
4734 Finally, test_support.HOST has been introduced, which should be used
4735 for the host argument of any relevant socket calls (i.e. bind and
4736 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004737
4738 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004739 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004740 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4741 test_asynchat and test_socket_ssl.
4742
Georg Brandl3ee81df2008-05-17 18:14:43 +00004743 It is now possible for multiple instances of the regression test
4744 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005023- Added the future_builtins module, which contains hex() and oct().
5024 These are the PEP 3127 version of these functions, designed to be
5025 compatible with the hex() and oct() builtins from Python 3.0. They
5026 differ slightly in their output formats from the existing, unchanged
5027 Python 2.6 builtins. The expected usage of the future_builtins
5028 module is:
5029 from future_builtins import hex, oct
5030
Eric Smith7ef40bf2008-02-20 23:34:22 +00005031- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5032 exponents for exponents with absolute value < 100. Follows C99
5033 standard. This is a change on Windows, which would use 3 digits.
5034 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5035 so that any alterations it does to the resulting string will be
5036 available in stringlib/formatter.h (for float.__format__).
5037
Eric Smith5a3c1352008-02-19 13:21:56 +00005038- Implemented PEP 3101, Advanced String Formatting. This adds a new
5039 builtin format(); a format() method for str and unicode; a
5040 __format__() method to object, str, unicode, int, long, float, and
5041 datetime; the class string.Formatter; and the C API
5042 PyObject_Format().
5043
Georg Brandl3ee81df2008-05-17 18:14:43 +00005044- Fixed several potential crashes, all caused by specially crafted
5045 __del__ methods exploiting objects in temporarily inconsistent
5046 state.

5050 a slot on a registered virtual subclass.

5056 in order to allow pymalloc to free more arenas. Python may give back
5057 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005058
Georg Brandl3ee81df2008-05-17 18:14:43 +00005059- Issue #2045: Fix an infinite recursion triggered when printing a
5060 subclass of collections.defaultdict, if its default_factory is set
5061 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005062
Christian Heimesf75dbef2008-02-08 00:11:31 +00005063- Fixed a minor memory leak in dictobject.c. The content of the free
5064 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00005066- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005067 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005068
Georg Brandl3ee81df2008-05-17 18:14:43 +00005069- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5070 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005071 to compact the internal free lists of pre-allocted ints and floats.
5072
Georg Brandl3ee81df2008-05-17 18:14:43 +00005073- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5074 calls. Python expected the return type int but the fork familie
5075 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005076
Georg Brandl3ee81df2008-05-17 18:14:43 +00005077- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5078 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005079
Georg Brandl3ee81df2008-05-17 18:14:43 +00005080- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5081 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005082
Georg Brandl3ee81df2008-05-17 18:14:43 +00005083- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5084 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00005086- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5087 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005088
Georg Brandl3ee81df2008-05-17 18:14:43 +00005089- Patch #1473257: generator objects gain a gi_code attribute. This is
5090 the same object as the func_code attribute of the function that
5091 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005092
Georg Brandl3ee81df2008-05-17 18:14:43 +00005093- Issue #1920: "while 0" statements were completely removed by the
5094 compiler, even in the presence of an "else" clause, which is
5095 supposed to be run when the condition is false. Now the compiler
5096 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005097
Guido van Rossumeead05f2008-01-24 18:21:02 +00005098- A few crashers fixed: weakref_in_del.py (issue #1377858);
5099 loosing_dict_ref.py (issue #1303614, test67.py);
5100 borrowed_ref_[34].py (not in tracker).
5101
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005102- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005103 suppressed while an extension is loaded by calling SetErrorMode in
5104 dynload_win.c. The error is still reported properly.
5105
Georg Brandl3ee81df2008-05-17 18:14:43 +00005106- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005107 several extension methods and modules do not work without unicode
5108 support.
5109
Georg Brandl26543b12008-01-21 18:36:51 +00005110- Issue #1882: when compiling code from a string, encoding cookies in the
5111 second line of code were not always recognized correctly.
5112
Georg Brandl14404b62008-01-19 19:27:05 +00005113- Issue #1679: "0x" was taken as a valid integer literal.
5114
Georg Brandl6caad7d2008-01-26 14:19:22 +00005115- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005116 added.
5117
Christian Heimesc94e2b52008-01-14 04:13:37 +00005118- sys.float_info / PyFloat_GetInfo: The floating point information
5119 object was converted from a dict to a specialized structseq object.
5120
Georg Brandl3ee81df2008-05-17 18:14:43 +00005121- Patch #1816: Added sys.flags structseq. It exposes the status of
5122 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005123
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- Objects/structseq.c: Implemented new structseq representation. The
5125 patch makes structseqs (e.g. the return value of os.stat) more
5126 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005127
Georg Brandl3ee81df2008-05-17 18:14:43 +00005128- Patch #1700288: added a type attribute cache that caches method
5129 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005130
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005131- Bug #1776: __import__() no longer accepts filenames on any platform.
5132 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005133
Georg Brandlaed6c662008-01-07 17:25:53 +00005134- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5135
Georg Brandl3ee81df2008-05-17 18:14:43 +00005136- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5137 envvar and sys.dont_write_bytecode attribute. All these can be set
5138 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005139
Georg Brandl3ee81df2008-05-17 18:14:43 +00005140- Improve some exception messages when Windows fails to load an
5141 extension module. Now we get for example '%1 is not a valid Win32
5142 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005143
Georg Brandl3ee81df2008-05-17 18:14:43 +00005144- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005146- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5147 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005148
Christian Heimes0a8143f2007-12-18 23:22:54 +00005149- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005150 and INF. float("nan"), float("inf") and float("-inf") now work on
5151 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005152
Georg Brandl3ee81df2008-05-17 18:14:43 +00005153- Compiler now generates simpler and faster code for dictionary
5154 literals. The oparg for BUILD_MAP now indicates an estimated
5155 dictionary size. There is a new opcode, STORE_MAP, for adding
5156 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00005157
Georg Brandl3ee81df2008-05-17 18:14:43 +00005158- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005166- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005167 SystemError.
5168
Nick Coghlanef01d822007-12-03 12:55:17 +00005169- PEP 366: Allow explicit relative imports when executing modules
5170 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00005185- Patch #1739468: Directories and zipfiles containing a __main__.py
5186 file can now be directly executed by passing their name to the
5187 interpreter. The directory/zipfile is automatically inserted as the
5188 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005189
Georg Brandl3ee81df2008-05-17 18:14:43 +00005190- Issue #1265: Fix a problem with sys.settrace, if the tracing
5191 function uses a generator expression when at the same time the
5192 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005193
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005194- sets and frozensets now have an isdisjoint() method.
5195
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005196- optimize the performance of builtin.sum().
5197
Neal Norwitz44f326e2007-10-05 05:29:17 +00005198- Fix warnings found by the new version of the Coverity checker.
5199
Georg Brandl21e99f42010-03-07 15:23:59 +00005200- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005201 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5202 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005203
Georg Brandl3ee81df2008-05-17 18:14:43 +00005204- Issue #1686386: Tuple's tp_repr did not take into account the
5205 possibility of having a self-referential tuple, which is possible
5206 from C code. Nor did object's tp_str consider that a type's tp_str
5207 could do something that could lead to an inifinite recursion.
5208 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5209 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005210
Georg Brandl3ee81df2008-05-17 18:14:43 +00005211- Issue #1164: It was possible to trigger deadlock when using the
5212 'print' statement to write to a file since the GIL was not released
5213 as needed. Now PyObject_Print() does the right thing along with
5214 various tp_print implementations of the built-in types and those in
5215 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005216
Georg Brandl3ee81df2008-05-17 18:14:43 +00005217- Issue #1147: Exceptions were directly allowing string exceptions in
5218 their throw() method even though string exceptions no longer
5219 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005220
Georg Brandl3ee81df2008-05-17 18:14:43 +00005221- Issue #1096: Prevent a segfault from getting the repr of a very
5222 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005223
Brett Cannon1e534b52007-09-07 04:18:30 +00005224- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225 PyObject_Call() never calling back out to Python code to trigger
5226 recursion depth updates/checks. Required the creation of a static
5227 RuntimeError instance in case normalizing an exception put the
5228 recursion check value past its limit. Fixes crashers
5229 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005230
Georg Brandl3ee81df2008-05-17 18:14:43 +00005231- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005244- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005245 __*__ attributes. (Some already existed, e.g., __doc__ and
5246 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005247
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005248- Add -3 option to the interpreter to warn about features that are
5249 deprecated and will be changed/removed in Python 3.0.
5250
Georg Brandl2134e752007-05-21 20:34:16 +00005251- Patch #1686487: you can now pass any mapping after '**' in function
5252 calls.
5253
Collin Winter62903052007-05-18 23:11:24 +00005254- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005255 "except E as target:". This is to provide forwards compatibility
5256 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005257
Brett Cannon229cee22007-05-05 01:34:02 +00005258- Deprecate BaseException.message as per PEP 352.
5259
Georg Brandl3ee81df2008-05-17 18:14:43 +00005260- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005261 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005262
Vinay Sajip8549ce32007-05-06 17:53:37 +00005263- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005264 setting a plain string, ie don't expand to single letter identifiers.
5265
Raymond Hettinger13936692007-04-11 18:40:58 +00005266- Request #1191699: Slices can now be pickled.
5267
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005268- Request #1193128: str.translate() now allows a None argument for
5269 translations that only remove characters without re-mapping the
5270 remaining characters.
5271
Georg Brandl5cb76c12007-03-21 09:00:39 +00005272- Patch #1682205: a TypeError while unpacking an iterable is no longer
5273 masked by a generic one with the message "unpack non-sequence".
5274
Neal Norwitzaa754b72007-03-21 06:39:48 +00005275- Remove unused file Python/fmod.c.
5276
Guido van Rossum143b5642007-03-23 04:58:42 +00005277- Bug #1683368: The object.__init__() and object.__new__() methods are
5278 now stricter in rejecting excess arguments. The only time when
5279 either allows excess arguments is when it is not overridden and the
5280 other one is. For backwards compatibility, when both are
5281 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005282 warning later). Also, type.__init__() insists on the same signature
5283 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005284
Georg Brandl3ee81df2008-05-17 18:14:43 +00005285- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5286 object to complex using its __complex__() method before falling back
5287 to the __float__() method. Therefore, the functions in the cmath
5288 module now can operate on objects that define a __complex__()
5289 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006363 time so that opening a database previously created with the DB_DUP
6364 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6365 opens. Specifically: dictionary assignment to a DB object will
6366 replace all values for a given key when the database allows
6367 duplicate values. DB users should use DB.put(k, v) when they want
6368 to store duplicates; not DB[k] = v.

6375 characters with ASCII value less than 32. Also, it correctly quotes
6376 dots only if they occur on a single line, as opposed to the previous
6377 behavior of quoting dots if they are the second character of any
6378 line.
