Antoine Pitrou5b4b2da2011-12-15 14:15:31 +010018- Fix the fix for issue #12149: it was incorrect, although it had the side
19 effect of appearing to resolve the issue. Thanks to Mark Shannon for
20 noticing.
21

24
Antoine Pitrou30402542011-11-15 01:49:40 +010025- Issue #13333: The UTF-7 decoder now accepts lone surrogates (the encoder

37 warnings. Patch by Josh Triplett and Petri Lehtinen.
38
Mark Hammond323b5da2011-10-17 11:05:36 +110039- Issue #7833: Extension modules built using distutils on Windows will no
40 longer include a "manifest" to prevent them failing at import time in some
41 embedded situations.
42
Benjamin Petersona7b09762011-10-15 13:43:21 -040043- Issue #13186: Fix __delitem__ on old-style instances when invoked through
44 PySequence_DelItem.

51
Mark Dickinsondbbed042011-09-19 16:38:08 +010052- Issue #12973: Fix overflow checks that invoked undefined behaviour in
53 int.__pow__. These overflow checks were causing int.__pow__ to produce
54 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010055 compiler optimizing the check away. Also fix similar overflow checks
56 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
57 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010058

66 non-exception class.
Benjamin Petersonc3349cd2011-07-15 14:15:40 -050067
Antoine Pitrou16166452011-07-12 22:04:20 +020068- Issue #12149: Update the method cache after a type's dictionnary gets
69 cleared by the garbage collector. This fixes a segfault when an instance
70 and its type get caught in a reference cycle, and the instance's
71 deallocator calls one of the methods on the type (e.g. when subclassing
72 IOBase). Diagnosis and patch by Davide Rizzo.
73
Florent Xiclunaa1f948b2012-01-24 21:05:10 +010074- Issue #12501: Remove Py3k warning for callable. callable() is supported

79
Victor Stinnerd3c7e172011-05-30 23:49:13 +020080- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +020081 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
82 raw_input() interrupted by CTRL+c.
83
Łukasz Langa7a153902011-10-18 17:16:00 +020084- Issue #10860: httplib now correctly handles an empty port after port
85 delimiter in URLs.
86
Barry Warsawc5643282011-07-19 17:06:30 -040087- dict_proxy objects now display their contents rather than just the class
88 name.

Éric Araujoa13cd392011-09-10 05:39:45 +020092
Petri Lehtinen587209f2012-02-12 21:03:02 +020093- Issue #9750: Fix sqlite3.Connection.iterdump on tables and fields
94 with a name that is a keyword or contains quotes. Patch by Marko
95 Kohtala.
96
Florent Xiclunac2279652012-02-12 14:49:03 +010097- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +010098 has left two versions of customize_compiler, the original in
99 distutils.sysconfig and another copy in distutils.ccompiler, with some
100 parts of distutils calling one and others using the other.
101 Complete the revert back to only having one in distutils.sysconfig as
102 is the case in 3.x.
103
Ned Deily0d0ea482012-02-10 12:59:06 +0100104- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
105 Distutils-based packages with C extension modules may fail because
106 Apple has removed gcc-4.2, the version used to build python.org
107 64-bit/32-bit Pythons. If the user does not explicitly override
108 the default C compiler by setting the CC environment variable,
109 Distutils will now attempt to compile extension modules with clang
110 if gcc-4.2 is required but not found. Also as a convenience, if
111 the user does explicitly set CC, substitute its value as the default
112 compiler in the Distutils LDSHARED configuration variable for OS X.
113 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
114 SDK, neither of which are available in Xcode 4. This change does not
115 attempt to override settings to support their use with Xcode 4.)
116
Senthil Kumaran59e7c8f2012-02-09 18:22:01 +0800117- Issue #9021: Add an introduction to the copy module documentation.
118
Senthil Kumaran607e31e2012-02-09 17:43:31 +0800119- Issue #6005: Examples in the socket library documentation use sendall, where
120 relevant, instead send method.
121
Petri Lehtinenc7fd5232011-05-09 12:24:09 +0200122- Issue #10811: Fix recursive usage of cursors. Instead of crashing,
123 raise a ProgrammingError now.
124
Ned Deily2c8bf042012-02-06 00:55:50 +0100125- Issue #10881: Fix test_site failures with OS X framework builds.

Ned Deily87e82bb2011-06-28 19:52:59 -0700390- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
391 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
392 interpreter process. This could cause failures in non-Distutils subprocesses
393 and was unreliable since tests or user programs could modify the interpreter
394 environment after Distutils set it. Instead, have Distutils set the the
395 deployment target only in the environment of each build subprocess. It is
396 still possible to globally override the default by setting
397 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
398 greater or equal to the default value, the value with which the interpreter
399 was built.

429 the ticker doesn't have to wind down to zero from the old starting point
430 before the new interval takes effect. And if the user increases the
431 interval, it makes sure the new limit takes effect right away rather have an
432 early task switch before recognizing the new interval.

903 accepted by ``time.mktime`` and ``time.strftime`` is still system
904 dependent, but ``time.mktime`` will now accept full range supported

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001823- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1824 start byte and the continuation byte(s) are now considered invalid, instead
1825 of the number of bytes specified by the start byte.
1826 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1827 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1828 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1829 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001837- Issue #8748: Fix two issues with comparisons between complex and integer
1838 objects. (1) The comparison could incorrectly return True in some cases
1839 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1840 (2) The comparison raised an OverflowError for large integers, leading
1841 to unpredictable exceptions when combining integers and complex objects
1842 in sets or dicts.

2036 operation raises multiple signals and more than one of those signals is
2037 trapped, the specification determines the order in which the signals should be
2038 handled. In many cases this order wasn't being followed, leading to the wrong

2225 with a non-empty format string. This is an effort to future-proof user
2226 code. If a derived class does not currently implement __format__ but later
2227 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002228 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002229 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002279- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2280 InvalidOperation instead of returning False. (Comparisons involving a quiet
2281 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2282 signaling NaNs remain unhashable.

2286 returned an arbitrary result based on the relative ordering of id(float) and
2287 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002289- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002290 argument `-` which tells it to read files to compile from stdin. Each line is
2291 read on demand and the named file is compiled immediately. (Original patch by
2292 Piotr Ożarowski).

2302 Fractions instance now raise TypeError instead of returning True/False. This
2303 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2304 <=> complex, and complex <=> complex comparisons.

2404 integer format code, struct.pack first attempts to convert the non-integer

2407
Georg Brandlba83f822010-03-14 09:50:54 +00002408- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2409 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2410 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002411 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2412 inconsistent: __int__ was used for some integer codes but not for others, and
2413 the set of integer codes for which it was used differed between native packing
2414 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002821- The ``__complex__()`` method is now looked up on the class of instances to
2822 make it consistent with other special methods.

2826
Mark Dickinson1b34d252010-01-01 17:27:30 +00002827- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002828 DeprecationWarning when passed a float argument where an integer was expected.
2829 These functions and methods now raise TypeError instead. The majority of the
2830 effects of this change are in the extension modules, but some core functions
2831 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2832 and many unicode/str methods.

2847 least on IEEE 754 platforms), and in particular does not depend on the
2848 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00002994- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
2995 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00002997- Issue #3382: 'F' formatting for float and complex now convert the result to
2998 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2999 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003000
Georg Brandlba83f822010-03-14 09:50:54 +00003001- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3002 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003003
Georg Brandlba83f822010-03-14 09:50:54 +00003004- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3005 1e-100 used to raise OverflowError, but now gives the requested 120
3006 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00003007
Georg Brandlba83f822010-03-14 09:50:54 +00003008- Add Py3k warnings for parameter names in parentheses.

3013 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003014
Georg Brandlba83f822010-03-14 09:50:54 +00003015- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3016 decimal string that's guaranteed to round back to x under correct rounding
3017 (with round-half-to-even rounding mode). Previously it gave a string based on
3018 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3019 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3020 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003021
Georg Brandlba83f822010-03-14 09:50:54 +00003022- Issue #7117: On almost all platforms: float-to-string and string-to-float
3023 conversions within Python are now correctly rounded. Places these conversions
3024 occur include: str for floats and complex numbers; the float and complex
3025 constructors; old-style and new-style numeric formatting; serialization and
3026 deserialization of floats and complex numbers using marshal, pickle and json;
3027 parsing of float and imaginary literals in Python code; Decimal-to-float
3028 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003029
Georg Brandlba83f822010-03-14 09:50:54 +00003030 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3031 providing correctly-rounded strtod and dtoa C functions. This code is
3032 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3033 the C compiler. There may be a small number of platforms on which correct
3034 operation of this code cannot be guaranteed, so the code is not used: notably,
3035 this applies to platforms where the C double format is not IEEE 754 binary64,
3036 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3037 and Python's configure script is unable to determine how to change the FPU
3038 precision. On these platforms conversions use the platform strtod and dtoa,
3039 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003040
Georg Brandlba83f822010-03-14 09:50:54 +00003041- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3042 uses the correctly-rounded string <-> float conversions described above (when
3043 available), and so produces correctly rounded results that will display nicely
3044 under the float repr. There are two related small changes: (1) round now
3045 accepts any class with an ``__index__()`` method for its second argument (but
3046 no longer accepts floats for the second argument), and (2) an excessively
3047 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3048 raises an exception.

3051
Georg Brandlba83f822010-03-14 09:50:54 +00003052- Fix several issues with ``compile()``. The input can now contain Windows and

3084 The tables for code points representing numeric values, white spaces or line
3085 breaks are now generated from the official Unicode Character Database files,
3086 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00003195- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3196 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3197 but with at least one decimal point and with a default precision
3198 of 12. Previously, the behavior the same but with a default precision of 6.
3199 This more closely matches ``str()``, and reduces surprises when adding

4827-----------------
4828
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004829- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4830
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004831- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4832 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4833 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4834 ``printf`` function, whereas PyString_FromFormat has an independent
4835 implementation and uses "%zd" on all platforms for size_t values.
4836 This makes a difference on win64, where ``printf`` needs "%Id" to display
4837 64bit values.
4838
Benjamin Peterson97179b02008-09-09 20:55:01 +00004839- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4840 error.
4841
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004842- Issue #3777: long() applied to a float object now always return a long
4843 object; previously an int would be returned for small values. the __long__
4844 method is allowed to return either an int or a long, but the behaviour of
4845 float objects should not change to respect backward compatibility.
4846
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004847- Issue #3751: str.rpartition would perform a left-partition when called with
4848 a unicode argument.
4849
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004850- Issue #3683: Fix compilation when --without-threads is given.
4851
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004852- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004853 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004854 was correctly parsed but parsing of subsequent arguments failed.
4855
Vinay Sajip35e3b032008-09-01 14:33:59 +00004856- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004857 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4858 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4859 when given a tuple of classes as second argument, were looking up
4860 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4861 type object.
4862
Neal Norwitz18aa3882008-08-24 05:04:52 +00004863- Fix crashes on memory allocation failure found with failmalloc.
4864
4865- Fix memory leaks found with valgrind and update suppressions file.
4866
4867- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4868
4869- Fix problem using wrong name in decimal module reported by pychecker.
4870
Christian Heimes7d4c3172008-08-22 19:47:25 +00004871- Silenced another compiler warning about a used but not defined
4872 function 'stringlib_contains_obj'.
4873
Benjamin Peterson712ee922008-08-24 18:10:20 +00004874- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
4875 ``__delslice__``.
4876
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004877- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4878 library targets in the Makefile.
4879
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004880- Issue #1204: The configure script now tests for additional libraries
4881 that may be required when linking against readline. This fixes issues
4882 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
4883

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00004892- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
4893 stack usage in the case of deeply nested objects.
4894

Nick Coghland2e09382008-09-11 12:11:06 +00004905- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004906 return a list or None rather than a custom object.
4907
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004908- Issue #1638033: Cookie.Morsel gained the httponly attribute.
4909
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00004910- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004932 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4933 for catch_warnings() also led to an improvement in the raising of a
4934 DeprecationWarning related to warnings.warn_explicit().
4935
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004936- The deprecation warnings for the old camelCase threading API were removed.

4958
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004959- Issue #2975: When compiling several extension modules with Visual Studio 2008
4960 from the same python interpreter, some environment variables would grow
4961 without limit.
4962
Benjamin Peterson37346b22008-08-23 20:27:43 +00004963- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4964 exploitation of poor argument checking.
4965
Gerhard Häringef2276b2008-09-12 13:54:06 +00004966- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005000What's New in Python 2.6 beta 3?
5001================================
5002
Barry Warsaw07a4a382008-08-21 01:15:08 +00005003*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005004
5005Core and Builtins
5006-----------------
5007
Guido van Rossumf8402962008-08-20 15:01:50 +00005008- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5009 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5010 extensions do not automatically benefit from the class attribute
5011 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5012 to their tp_flags field if they care. This is a backwards
5013 compatibility feature; in 3.0, all types will use the cache by
5014 default.
5015
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005016- Keyword arguments can now follow starred arguments. (``f(a, *args,
5017 keyword=23)`` is now valid syntax.)
5018
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005019- ctypes function pointers that are COM methods have a boolean True
5020 value again.
5021
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005022- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5023 by denying s# to parse objects that have a releasebuffer procedure,
5024 and introducing s*.
5025
Georg Brandl1e13ea92008-08-11 09:07:59 +00005026- Issue #3537: Fix an assertion failure when an empty but presized dict
5027 object was stored in the freelist.
5028
Mark Dickinsonb6467572008-08-04 21:30:09 +00005029- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5030 ValueError consistently across platforms.
5031
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005032- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5033 (64bit Unix, for example), unichr() would truncate its argument and return
5034 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5035
Neal Norwitze7d8be82008-07-31 17:17:14 +00005036- Apply security patches from Apple.
5037
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005038- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5039 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5040
Antoine Pitrou92f82162008-07-25 22:22:08 +00005041- Issue #1819: function calls with several named parameters are now on
5042 average 35% faster (as measured by pybench).
5043
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005044- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5045 the python debugger steps into a class statement: the free variables (local
5046 variables defined in an outer scope) would be deleted from the outer scope.
5047
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005048- Issue #2620: Overflow checking when allocating or reallocating memory
5049 was not always being done properly in some python types and extension
5050 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5051 all been updated to perform better checks and places in the code that
5052 would previously leak memory on the error path when such an allocation
5053 failed have been fixed.

5056-------
5057
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005058- Issue #3612: Added some missing basic types in ctypes.wintypes.
5059
Benjamin Petersone977ad42008-08-20 01:42:01 +00005060- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5061 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5062
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005063- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5064 version reported by these tools does not necessarily follow the python
5065 version numbering scheme, so the module is less strict when parsing it.
5066
Nick Coghlanf70385a2008-08-18 12:42:46 +00005067- Issue #2235: Added Py3k warnings for types which will become unhashable
5068 under the stricter __hash__ inheritance rules in 3.0. Several types
5069 which did not meet the rules for hash invariants and were already
5070 unhashable in 3.0 have now been explicitly flagged as unhashable in
5071 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5072 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5073
Brett Cannon88f801d2008-08-18 00:46:22 +00005074- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5082
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005083- Issue #3575: Incremental decoder's decode function now takes bytearray
5084 by using 's*' instead of 't#'.
5085
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005086- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005087 fails unicode conversion on 2nd parameter. (windows only)
5088
Georg Brandl222e2082010-08-01 22:27:39 +00005089- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005090 in a redirect.
5091
Brett Cannonabe423e2008-08-16 21:47:07 +00005092- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005093 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005094
Facundo Batistaeb90b782008-08-16 14:44:07 +00005095- Issue #2776: fixed small issue when handling an URL with double slash
5096 after a 302 response in the case of not going through a proxy.
5097
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005098- Issue #2676: in the email package, content-type parsing was hanging on
5099 pathological input because of quadratic or exponential behaviour of a
5100 regular expression.
5101
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005102- Issue #3476: binary buffered reading through the new "io" library is now
5103 thread-safe.
5104
Brett Cannonbf3157b2008-08-14 05:00:03 +00005105- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5106 since mimetools itself is deprecated. Because modules are cached, all
5107 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5108

Antoine Pitroude781a42008-08-09 12:43:23 +00005143 asking for a specific length. This problem only affected files opened

5187
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005188- Issue #643841: The language reference now provides more detailed

5200-----------------
5201
Georg Brandl3e483f62008-07-16 22:57:41 +00005202- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5203 its methods now allow for items objects that can be converted to
5204 an integer using operator.index().
5205
Mark Dickinson64b7e502008-07-16 09:40:03 +00005206- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5207 produced a ValueError instead of giving the correct float.
5208
Eric Smitha5fa5a22008-07-16 00:11:49 +00005209- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5210 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5211
Mark Dickinson7103aa42008-07-15 19:08:33 +00005212- Issue #3008: the float type has a new instance method 'float.hex'
5213 and a new class method 'float.fromhex' to convert floating-point
5214 numbers to and from hexadecimal strings, respectively.
5215
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005216- Issue #2235: __hash__ is once again inherited by default. To allow
5217 collections.Hashable to remain meaningful in the presence of the
5218 default hash implementation (object.__hash__), it is now possible
5219 to explicit block inheritance of hash by setting __hash__=None at
5220 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5221 level.
5222
Nick Coghlanb028f502008-07-13 14:52:36 +00005223- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5224 the parent module cannot be found while performing an absolute import.
5225 This means that an incorrectly defined __package__ attribute will
5226 now only prevent relative imports in that module rather than causing
5227 all imports from that module to fail.
5228
Nick Coghlan14ff9942008-07-08 14:21:42 +00005229- Issue #2517: Allow unicode messages in Exceptions again by correctly

5239 another thread's dictionary.
5240
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005241- Issue #3004: Minor change to slice.indices(): the start and stop
5242 arguments are now treated identically, making the behaviour easier
5243 to describe and understand. For example, slice(None, -10,
5244 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5245 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5246 10, -1).
5247
Georg Brandl278fc502008-07-19 12:46:12 +00005248- Issue #3219: Calling a function with repeated keyword arguments,
5249 f(a=2, a=23), would not cause a syntax error. This was a regression
5250 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005251
Georg Brandl278fc502008-07-19 12:46:12 +00005252- Issue #2862: Make int and float freelist management consistent with
5253 other freelists. Changes their CompactFreeList apis into

5261 error when they failed.
5262
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005263- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005288- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5289 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005290 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005291 content-length. The problem had been corrected in the 2.4 branch, but never
5292 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005307- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5676 in Python 3.0.
Benjamin Peterson23681932008-05-12 21:42:13 +00005677
Vinay Sajip9828b7e2008-06-17 11:04:02 +00005678- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005679 environment to control the '-arch' flags that are used to build
5680 an extension. This was added for compatibility with Apple's build
5681 of Python.
5682
5683- The bundled OSX-specific copy of libbffi is now in sync with the version
5684 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
5685
Georg Brandl25c34082008-08-18 23:09:49 +00005686- The threading module gained aliases for names that will be removed in the

5695
Brett Cannonb61d8012008-05-11 23:39:04 +00005696- ``Lib/lib-old`` is now added to sys.path.
5697
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005698- On MacOS X it is now possible to install the framework in 64-bit
5699 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005700 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005701
5702 This is controlled by the configure argument ``--with-universal-archs``:
5703
5704 - ``--with-universal-archs=all``: install 4-way universal
5705
5706 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5707
5708 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5709
5710 This option should be used in combination with ``--enable-universalsdk=``.
5711
5712 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00005762- Issue #1631171: Re-implement the 'warnings' module in C (the
5763 original Python code has been kept as backup). This will allow for
5764 using the 'warning's machinery in such places as the parser where
5765 use of pure Python code is not possible. Both the ``showarning()``
5766 and ``formatwarning()`` gain an optional 'line' argument which is
5767 not called by default for backwards-compatibility reasons. Setting
5768 ``warnings.showwarning()`` to an implementation that lacks support
5769 for the ``line`` argument will raise a DeprecationWarning.

5793
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005794- The getpass module has been improved on Unix. It now uses /dev/tty
5795 by default and uses stderr instead of stdout. A GetPassWarning is
5796 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005811- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005812 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005832- Issue #2550: The approach used by client/server code for obtaining
5833 ports to listen on in network-oriented tests has been refined in an
5834 effort to facilitate running multiple instances of the entire
5835 regression test suite in parallel without issue.
5836 test_support.bind_port() has been fixed such that it will always
5837 return a unique port -- which wasn't always the case with the
5838 previous implementation, especially if socket options had been set
5839 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5840 new implementation of bind_port() will actually raise an exception
5841 if it is passed an AF_INET/SOCK_STREAM socket with either the
5842 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5843 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5844 the socket it's been passed. This currently only applies to
5845 Windows. This option prevents any other sockets from binding to the
5846 host/port we've bound to, thus removing the possibility of the
5847 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5848 when a second SOCK_STREAM socket binds and accepts to a host/port
5849 that's already been bound by another socket. The optional preferred
5850 port parameter to bind_port() has been removed. Under no
5851 circumstances should tests be hard coding ports!
5852
5853 test_support.find_unused_port() has also been introduced, which will
5854 pass a temporary socket object to bind_port() in order to obtain an
5855 unused port. The temporary socket object is then closed and
5856 deleted, and the port is returned. This method should only be used
5857 for obtaining an unused port in order to pass to an external program
5858 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5859 a parameter to a server-oriented class that doesn't give you direct
5860 access to the underlying socket used.
5861
5862 Finally, test_support.HOST has been introduced, which should be used
5863 for the host argument of any relevant socket calls (i.e. bind and
5864 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005865
5866 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005867 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005868 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5869 test_asynchat and test_socket_ssl.
5870
Georg Brandl3ee81df2008-05-17 18:14:43 +00005871 It is now possible for multiple instances of the regression test
5872 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006151- Added the future_builtins module, which contains hex() and oct().
6152 These are the PEP 3127 version of these functions, designed to be
6153 compatible with the hex() and oct() builtins from Python 3.0. They
6154 differ slightly in their output formats from the existing, unchanged
6155 Python 2.6 builtins. The expected usage of the future_builtins
6156 module is:
6157 from future_builtins import hex, oct
6158
Eric Smith7ef40bf2008-02-20 23:34:22 +00006159- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6160 exponents for exponents with absolute value < 100. Follows C99
6161 standard. This is a change on Windows, which would use 3 digits.
6162 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6163 so that any alterations it does to the resulting string will be
6164 available in stringlib/formatter.h (for float.__format__).
6165
Eric Smith5a3c1352008-02-19 13:21:56 +00006166- Implemented PEP 3101, Advanced String Formatting. This adds a new
6167 builtin format(); a format() method for str and unicode; a
6168 __format__() method to object, str, unicode, int, long, float, and
6169 datetime; the class string.Formatter; and the C API
6170 PyObject_Format().
6171
Georg Brandl3ee81df2008-05-17 18:14:43 +00006172- Fixed several potential crashes, all caused by specially crafted
6173 __del__ methods exploiting objects in temporarily inconsistent
6174 state.

6178 a slot on a registered virtual subclass.

6184 in order to allow pymalloc to free more arenas. Python may give back
6185 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006186
Georg Brandl3ee81df2008-05-17 18:14:43 +00006187- Issue #2045: Fix an infinite recursion triggered when printing a
6188 subclass of collections.defaultdict, if its default_factory is set
6189 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006190
Christian Heimesf75dbef2008-02-08 00:11:31 +00006191- Fixed a minor memory leak in dictobject.c. The content of the free
6192 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00006194- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006195 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006196
Georg Brandl3ee81df2008-05-17 18:14:43 +00006197- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6198 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006199 to compact the internal free lists of pre-allocted ints and floats.
6200
Georg Brandl3ee81df2008-05-17 18:14:43 +00006201- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6202 calls. Python expected the return type int but the fork familie
6203 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006204
Georg Brandl3ee81df2008-05-17 18:14:43 +00006205- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6206 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006207
Georg Brandl3ee81df2008-05-17 18:14:43 +00006208- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6209 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006210
Georg Brandl3ee81df2008-05-17 18:14:43 +00006211- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6212 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006213
Georg Brandl3ee81df2008-05-17 18:14:43 +00006214- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6215 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006216
Georg Brandl3ee81df2008-05-17 18:14:43 +00006217- Patch #1473257: generator objects gain a gi_code attribute. This is
6218 the same object as the func_code attribute of the function that
6219 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006220
Georg Brandl3ee81df2008-05-17 18:14:43 +00006221- Issue #1920: "while 0" statements were completely removed by the
6222 compiler, even in the presence of an "else" clause, which is
6223 supposed to be run when the condition is false. Now the compiler
6224 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006225
Guido van Rossumeead05f2008-01-24 18:21:02 +00006226- A few crashers fixed: weakref_in_del.py (issue #1377858);
6227 loosing_dict_ref.py (issue #1303614, test67.py);
6228 borrowed_ref_[34].py (not in tracker).
6229
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006230- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006231 suppressed while an extension is loaded by calling SetErrorMode in
6232 dynload_win.c. The error is still reported properly.
6233
Georg Brandl3ee81df2008-05-17 18:14:43 +00006234- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006235 several extension methods and modules do not work without unicode
6236 support.
6237
Georg Brandl26543b12008-01-21 18:36:51 +00006238- Issue #1882: when compiling code from a string, encoding cookies in the
6239 second line of code were not always recognized correctly.
6240
Georg Brandl14404b62008-01-19 19:27:05 +00006241- Issue #1679: "0x" was taken as a valid integer literal.
6242
Georg Brandl6caad7d2008-01-26 14:19:22 +00006243- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006244 added.
6245
Christian Heimesc94e2b52008-01-14 04:13:37 +00006246- sys.float_info / PyFloat_GetInfo: The floating point information
6247 object was converted from a dict to a specialized structseq object.
6248
Georg Brandl3ee81df2008-05-17 18:14:43 +00006249- Patch #1816: Added sys.flags structseq. It exposes the status of
6250 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006251
Georg Brandl3ee81df2008-05-17 18:14:43 +00006252- Objects/structseq.c: Implemented new structseq representation. The
6253 patch makes structseqs (e.g. the return value of os.stat) more
6254 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006255
Georg Brandl3ee81df2008-05-17 18:14:43 +00006256- Patch #1700288: added a type attribute cache that caches method
6257 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006258
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006259- Bug #1776: __import__() no longer accepts filenames on any platform.
6260 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006261
Georg Brandlaed6c662008-01-07 17:25:53 +00006262- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6263
Georg Brandl3ee81df2008-05-17 18:14:43 +00006264- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6265 envvar and sys.dont_write_bytecode attribute. All these can be set
6266 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006267
Georg Brandl3ee81df2008-05-17 18:14:43 +00006268- Improve some exception messages when Windows fails to load an
6269 extension module. Now we get for example '%1 is not a valid Win32
6270 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006271
Georg Brandl3ee81df2008-05-17 18:14:43 +00006272- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006274- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6275 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006276
Christian Heimes0a8143f2007-12-18 23:22:54 +00006277- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006278 and INF. float("nan"), float("inf") and float("-inf") now work on
6279 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006280
Georg Brandl3ee81df2008-05-17 18:14:43 +00006281- Compiler now generates simpler and faster code for dictionary
6282 literals. The oparg for BUILD_MAP now indicates an estimated
6283 dictionary size. There is a new opcode, STORE_MAP, for adding
6284 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006285
Georg Brandl3ee81df2008-05-17 18:14:43 +00006286- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006291- Issue #1538: Avoid copying string in split/rsplit if the split char
6292 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006293
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006294- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006295 SystemError.
6296
Nick Coghlanef01d822007-12-03 12:55:17 +00006297- PEP 366: Allow explicit relative imports when executing modules
6298 inside packages with the -m switch via a new module level
6299 __package__ attribute.

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006308 attribute of an empty cell object.
6309
Georg Brandl3ee81df2008-05-17 18:14:43 +00006310- Issue #1460: The utf-7 incremental decoder did not accept truncated
6311 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006312
Georg Brandl3ee81df2008-05-17 18:14:43 +00006313- Patch #1739468: Directories and zipfiles containing a __main__.py
6314 file can now be directly executed by passing their name to the
6315 interpreter. The directory/zipfile is automatically inserted as the
6316 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006317
Georg Brandl3ee81df2008-05-17 18:14:43 +00006318- Issue #1265: Fix a problem with sys.settrace, if the tracing
6319 function uses a generator expression when at the same time the
6320 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006321
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006322- sets and frozensets now have an isdisjoint() method.
6323
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006324- optimize the performance of builtin.sum().
6325
Neal Norwitz44f326e2007-10-05 05:29:17 +00006326- Fix warnings found by the new version of the Coverity checker.
6327
Georg Brandl21e99f42010-03-07 15:23:59 +00006328- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006329 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6330 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006331
Georg Brandl3ee81df2008-05-17 18:14:43 +00006332- Issue #1686386: Tuple's tp_repr did not take into account the
6333 possibility of having a self-referential tuple, which is possible
6334 from C code. Nor did object's tp_str consider that a type's tp_str
6335 could do something that could lead to an inifinite recursion.
6336 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6337 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006338
Georg Brandl3ee81df2008-05-17 18:14:43 +00006339- Issue #1164: It was possible to trigger deadlock when using the
6340 'print' statement to write to a file since the GIL was not released
6341 as needed. Now PyObject_Print() does the right thing along with
6342 various tp_print implementations of the built-in types and those in
6343 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006344
Georg Brandl3ee81df2008-05-17 18:14:43 +00006345- Issue #1147: Exceptions were directly allowing string exceptions in
6346 their throw() method even though string exceptions no longer
6347 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006348
Georg Brandl3ee81df2008-05-17 18:14:43 +00006349- Issue #1096: Prevent a segfault from getting the repr of a very
6350 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006351
Brett Cannon1e534b52007-09-07 04:18:30 +00006352- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006353 PyObject_Call() never calling back out to Python code to trigger
6354 recursion depth updates/checks. Required the creation of a static
6355 RuntimeError instance in case normalizing an exception put the
6356 recursion check value past its limit. Fixes crashers
6357 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006358
Georg Brandl3ee81df2008-05-17 18:14:43 +00006359- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006372- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006373 __*__ attributes. (Some already existed, e.g., __doc__ and
6374 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006375
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006376- Add -3 option to the interpreter to warn about features that are
6377 deprecated and will be changed/removed in Python 3.0.
6378
Georg Brandl2134e752007-05-21 20:34:16 +00006379- Patch #1686487: you can now pass any mapping after '**' in function
6380 calls.
6381
Collin Winter62903052007-05-18 23:11:24 +00006382- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006383 "except E as target:". This is to provide forwards compatibility
6384 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006385
Brett Cannon229cee22007-05-05 01:34:02 +00006386- Deprecate BaseException.message as per PEP 352.
6387
Georg Brandl3ee81df2008-05-17 18:14:43 +00006388- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006389 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006390
Vinay Sajip8549ce32007-05-06 17:53:37 +00006391- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006392 setting a plain string, ie don't expand to single letter identifiers.
6393
Raymond Hettinger13936692007-04-11 18:40:58 +00006394- Request #1191699: Slices can now be pickled.
6395
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006396- Request #1193128: str.translate() now allows a None argument for
6397 translations that only remove characters without re-mapping the
6398 remaining characters.
6399
Georg Brandl5cb76c12007-03-21 09:00:39 +00006400- Patch #1682205: a TypeError while unpacking an iterable is no longer
6401 masked by a generic one with the message "unpack non-sequence".
6402
Neal Norwitzaa754b72007-03-21 06:39:48 +00006403- Remove unused file Python/fmod.c.
6404
Guido van Rossum143b5642007-03-23 04:58:42 +00006405- Bug #1683368: The object.__init__() and object.__new__() methods are
6406 now stricter in rejecting excess arguments. The only time when
6407 either allows excess arguments is when it is not overridden and the
6408 other one is. For backwards compatibility, when both are
6409 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006410 warning later). Also, type.__init__() insists on the same signature
6411 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006412
Georg Brandl3ee81df2008-05-17 18:14:43 +00006413- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6414 object to complex using its __complex__() method before falling back
6415 to the __float__() method. Therefore, the functions in the cmath
6416 module now can operate on objects that define a __complex__()
6417 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006418
Georg Brandl3ee81df2008-05-17 18:14:43 +00006419- Patch #1623563: allow __class__ assignment for classes with
6420 __slots__. The old and the new class are still required to have the
6421 same slot names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007491 time so that opening a database previously created with the DB_DUP
7492 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7493 opens. Specifically: dictionary assignment to a DB object will
7494 replace all values for a given key when the database allows
7495 duplicate values. DB users should use DB.put(k, v) when they want
7496 to store duplicates; not DB[k] = v.

7505 behavior of quoting dots if they are the second character of any
7506 line.
