16 is modified during the lifetime of the Python process after zipimport has

1625 In particular, fix extension module build failures when trying to use
1626 32-bit-only installer Pythons on systems with Xcode 4 (currently
1627 OS X 10.8, 10.7, and optionally 10.6).
1628 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1629 * Since Xcode 4 removes ppc support, extension module builds now
1630 check for ppc compiler support and by default remove ppc and
1631 ppc64 archs when they are not available.
1632 * Extension module builds now revert to using system installed
1633 headers and libs (/usr and /System/Library) if the SDK used
1634 to build the interpreter is not installed or has moved.
1635 * Try to avoid building extension modules with deprecated
1636 and problematic Apple llvm-gcc compiler. If original compiler
1637 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002061- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002062 has left two versions of customize_compiler, the original in
2063 distutils.sysconfig and another copy in distutils.ccompiler, with some
2064 parts of distutils calling one and others using the other.
2065 Complete the revert back to only having one in distutils.sysconfig as
2066 is the case in 3.x.
2067
Ned Deily0d0ea482012-02-10 12:59:06 +01002068- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2069 Distutils-based packages with C extension modules may fail because
2070 Apple has removed gcc-4.2, the version used to build python.org
2071 64-bit/32-bit Pythons. If the user does not explicitly override
2072 the default C compiler by setting the CC environment variable,
2073 Distutils will now attempt to compile extension modules with clang
2074 if gcc-4.2 is required but not found. Also as a convenience, if
2075 the user does explicitly set CC, substitute its value as the default
2076 compiler in the Distutils LDSHARED configuration variable for OS X.
2077 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2078 SDK, neither of which are available in Xcode 4. This change does not
2079 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002329- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2330 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2331 interpreter process. This could cause failures in non-Distutils subprocesses
2332 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002333 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002334 deployment target only in the environment of each build subprocess. It is
2335 still possible to globally override the default by setting
2336 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2337 greater or equal to the default value, the value with which the interpreter
2338 was built.

2368 the ticker doesn't have to wind down to zero from the old starting point
2369 before the new interval takes effect. And if the user increases the
2370 interval, it makes sure the new limit takes effect right away rather have an
2371 early task switch before recognizing the new interval.

3352 This prevents user-created self-referencing ordered dictionaries from
3353 becoming permanently uncollectable GC garbage. The downside is that

3813
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003814- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3815 start byte and the continuation byte(s) are now considered invalid, instead
3816 of the number of bytes specified by the start byte.
3817 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3818 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3819 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3820 Previous versions returned a single u'\ufffd'.

3824 arises from the "Overriding __eq__ blocks inheritance ..." warning
3825 when turned into an exception: in this case the exception simply
3826 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003828- Issue #8748: Fix two issues with comparisons between complex and integer
3829 objects. (1) The comparison could incorrectly return True in some cases
3830 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3831 (2) The comparison raised an OverflowError for large integers, leading
3832 to unpredictable exceptions when combining integers and complex objects
3833 in sets or dicts.
3834
Mark Dickinson81336372010-05-30 12:12:25 +00003835- Issue #5211: Implicit coercion for the complex type is now completely
3836 removed. (Coercion for arithmetic operations was already removed in 2.7
3837 alpha 4, but coercion for rich comparisons was accidentally left in.)
3838
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003839- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

4216 with a non-empty format string. This is an effort to future-proof user
4217 code. If a derived class does not currently implement __format__ but later
4218 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004219 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004220 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004270- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4271 InvalidOperation instead of returning False. (Comparisons involving a quiet
4272 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4273 signaling NaNs remain unhashable.

4277 returned an arbitrary result based on the relative ordering of id(float) and
4278 id(Decimal).

4282 read on demand and the named file is compiled immediately. (Original patch by

4294 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4295 <=> complex, and complex <=> complex comparisons.

4404 the set of integer codes for which it was used differed between native packing
4405 and standard packing.)

4658 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4659 returning NULL. The macro now returns a statically allocated empty string
4660 instead.

4670 strings,
4671 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4672 numeric strings corresponding to subnormal values,
4673 (3) a memory leak for some values large enough to cause overflow, and
4674 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00004705- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004706 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004707 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004712- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004713 file position when calling `truncate()`. It would previously change the file
4714 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004715 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4716

4718 class used to represent files stored inside an archive. The new
4719 implementation is significantly faster and can be wrapped in a
4720 ``io.BufferedReader`` object for more speedups. It also solves an issue
4721 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4722 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004732- Issue #7748: Since unicode values are supported for some metadata options in

4811
Georg Brandlba83f822010-03-14 09:50:54 +00004812- The ``__complex__()`` method is now looked up on the class of instances to
4813 make it consistent with other special methods.

4817
Mark Dickinson1b34d252010-01-01 17:27:30 +00004818- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004819 DeprecationWarning when passed a float argument where an integer was expected.
4820 These functions and methods now raise TypeError instead. The majority of the
4821 effects of this change are in the extension modules, but some core functions
4822 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4823 and many unicode/str methods.

4835
Georg Brandlba83f822010-03-14 09:50:54 +00004836- Issue #1811: Improve accuracy and cross-platform consistency for true division
4837 of integers: the result of a/b is now correctly rounded for ints a and b (at
4838 least on IEEE 754 platforms), and in particular does not depend on the
4839 internal representation of a long.

4847
Georg Brandlba83f822010-03-14 09:50:54 +00004848 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004984- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
4985 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004986
Georg Brandlba83f822010-03-14 09:50:54 +00004987- Issue #3382: 'F' formatting for float and complex now convert the result to
4988 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4989 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004990
Georg Brandlba83f822010-03-14 09:50:54 +00004991- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4992 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004993
Georg Brandlba83f822010-03-14 09:50:54 +00004994- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4995 1e-100 used to raise OverflowError, but now gives the requested 120
4996 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004997
Georg Brandlba83f822010-03-14 09:50:54 +00004998- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00004999
Georg Brandlba83f822010-03-14 09:50:54 +00005000- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00005001
Georg Brandlba83f822010-03-14 09:50:54 +00005002- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
5003 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005004
Georg Brandlba83f822010-03-14 09:50:54 +00005005- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5006 decimal string that's guaranteed to round back to x under correct rounding
5007 (with round-half-to-even rounding mode). Previously it gave a string based on
5008 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5009 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5010 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005011
Georg Brandlba83f822010-03-14 09:50:54 +00005012- Issue #7117: On almost all platforms: float-to-string and string-to-float
5013 conversions within Python are now correctly rounded. Places these conversions
5014 occur include: str for floats and complex numbers; the float and complex
5015 constructors; old-style and new-style numeric formatting; serialization and
5016 deserialization of floats and complex numbers using marshal, pickle and json;
5017 parsing of float and imaginary literals in Python code; Decimal-to-float
5018 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005019
Georg Brandlba83f822010-03-14 09:50:54 +00005020 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5021 providing correctly-rounded strtod and dtoa C functions. This code is
5022 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5023 the C compiler. There may be a small number of platforms on which correct
5024 operation of this code cannot be guaranteed, so the code is not used: notably,
5025 this applies to platforms where the C double format is not IEEE 754 binary64,
5026 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5027 and Python's configure script is unable to determine how to change the FPU
5028 precision. On these platforms conversions use the platform strtod and dtoa,
5029 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005030
Georg Brandlba83f822010-03-14 09:50:54 +00005031- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5032 uses the correctly-rounded string <-> float conversions described above (when
5033 available), and so produces correctly rounded results that will display nicely
5034 under the float repr. There are two related small changes: (1) round now
5035 accepts any class with an ``__index__()`` method for its second argument (but
5036 no longer accepts floats for the second argument), and (2) an excessively
5037 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5038 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00005039
Philip Jenveyfab8be22009-11-17 02:42:26 +00005040- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
5041
Georg Brandlba83f822010-03-14 09:50:54 +00005042- Fix several issues with ``compile()``. The input can now contain Windows and
5043 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00005044
Georg Brandlba83f822010-03-14 09:50:54 +00005045- Remove length limitation when constructing a complex number from a unicode
5046 string.
Mark Dickinsonc04c7c52009-10-26 22:28:14 +00005047
Georg Brandlba83f822010-03-14 09:50:54 +00005048- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
5049 during the formation of an output tuple.
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +00005050
Mark Dickinson8d87dc02009-10-25 20:39:06 +00005051- Issue #1087418: Boost performance of bitwise operations for longs.
5052
Georg Brandlba83f822010-03-14 09:50:54 +00005053- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
5054 which fixes the problem of some exceptions being thrown at shutdown when the
5055 interpreter is killed. Patch by Adam Olsen.
Antoine Pitrouefb60c02009-10-20 21:29:37 +00005056
Georg Brandlba83f822010-03-14 09:50:54 +00005057- Issue #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``,
5058 and note that they are unsafe and deprecated.
Eric Smithc12781a2009-10-19 14:38:14 +00005059
Georg Brandlba83f822010-03-14 09:50:54 +00005060- Issue #7120: logging: Remove import of multiprocessing which is causing crash
5061 in GAE.
Vinay Sajip03d5c342009-10-16 14:06:44 +00005062
Georg Brandlba83f822010-03-14 09:50:54 +00005063- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
5064 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +00005065
Georg Brandlba83f822010-03-14 09:50:54 +00005066- Issue #1754094: Improve the stack depth calculation in the compiler. There
5067 should be no other effect than a small decrease in memory use. Patch by
5068 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00005069
Georg Brandlba83f822010-03-14 09:50:54 +00005070- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
5071 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +00005072
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00005073- Issue #1571184: The Unicode database contains properties for more characters.
5074 The tables for code points representing numeric values, white spaces or line
5075 breaks are now generated from the official Unicode Character Database files,
5076 and include information from the Unihan.txt file.
5077

5082 running through the shell. Patch by Jean-Paul Calderone and Jani Hakala.
Philip Jenvey8b902042009-09-29 19:10:15 +00005083
Georg Brandlba83f822010-03-14 09:50:54 +00005084- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005180
Georg Brandlba83f822010-03-14 09:50:54 +00005181 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5182 (2) parsing of strings representing infinities and nans was locale aware; and

Georg Brandlba83f822010-03-14 09:50:54 +00005185- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5186 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5187 but with at least one decimal point and with a default precision
5188 of 12. Previously, the behavior the same but with a default precision of 6.
5189 This more closely matches ``str()``, and reduces surprises when adding
5190 alignment flags to the empty presentation type. This also affects the new
5191 complex.__format__ in the same way.
5192
5193- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5194 classtype's, even if it was None. property now inserts the __doc__ into the

Walter Dörwalded960ac2009-05-03 22:36:33 +00005443- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5444 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

5453 gives improved memory leak detection when running under Valgrind, while taking
5454 advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006824- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6825 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6826 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6827 ``printf`` function, whereas PyString_FromFormat has an independent
6828 implementation and uses "%zd" on all platforms for size_t values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006832- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6833 error.
6834
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006835- Issue #3777: long() applied to a float object now always return a long
6836 object; previously an int would be returned for small values. the __long__
6837 method is allowed to return either an int or a long, but the behaviour of
6838 float objects should not change to respect backward compatibility.
6839
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006840- Issue #3751: str.rpartition would perform a left-partition when called with
6841 a unicode argument.
6842
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006843- Issue #3683: Fix compilation when --without-threads is given.
6844
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006845- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006846 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006847 was correctly parsed but parsing of subsequent arguments failed.
6848
Vinay Sajip35e3b032008-09-01 14:33:59 +00006849- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006850 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6851 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6852 when given a tuple of classes as second argument, were looking up
6853 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6854 type object.
6855
Neal Norwitz18aa3882008-08-24 05:04:52 +00006856- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006925 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6926 for catch_warnings() also led to an improvement in the raising of a
6927 DeprecationWarning related to warnings.warn_explicit().
6928

6955
Benjamin Peterson37346b22008-08-23 20:27:43 +00006956- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

6998Core and Builtins
6999-----------------
7000
Guido van Rossumf8402962008-08-20 15:01:50 +00007001- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7002 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7003 extensions do not automatically benefit from the class attribute
7004 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7005 to their tp_flags field if they care. This is a backwards
7006 compatibility feature; in 3.0, all types will use the cache by
7007 default.
7008
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007009- Keyword arguments can now follow starred arguments. (``f(a, *args,
7010 keyword=23)`` is now valid syntax.)
7011
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007012- ctypes function pointers that are COM methods have a boolean True
7013 value again.
7014
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007015- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7016 by denying s# to parse objects that have a releasebuffer procedure,
7017 and introducing s*.
7018
Georg Brandl1e13ea92008-08-11 09:07:59 +00007019- Issue #3537: Fix an assertion failure when an empty but presized dict
7020 object was stored in the freelist.
7021
Mark Dickinsonb6467572008-08-04 21:30:09 +00007022- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7023 ValueError consistently across platforms.
7024
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007025- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7026 (64bit Unix, for example), unichr() would truncate its argument and return
7027 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7028
Neal Norwitze7d8be82008-07-31 17:17:14 +00007029- Apply security patches from Apple.
7030
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007031- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7032 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7033
Antoine Pitrou92f82162008-07-25 22:22:08 +00007034- Issue #1819: function calls with several named parameters are now on
7035 average 35% faster (as measured by pybench).
7036
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007037- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7038 the python debugger steps into a class statement: the free variables (local
7039 variables defined in an outer scope) would be deleted from the outer scope.
7040
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007041- Issue #2620: Overflow checking when allocating or reallocating memory
7042 was not always being done properly in some python types and extension
7043 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7044 all been updated to perform better checks and places in the code that
7045 would previously leak memory on the error path when such an allocation
7046 failed have been fixed.

7049-------
7050
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007051- Issue #3612: Added some missing basic types in ctypes.wintypes.
7052
Benjamin Petersone977ad42008-08-20 01:42:01 +00007053- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7054 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7055
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007056- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7057 version reported by these tools does not necessarily follow the python
7058 version numbering scheme, so the module is less strict when parsing it.
7059
Nick Coghlanf70385a2008-08-18 12:42:46 +00007060- Issue #2235: Added Py3k warnings for types which will become unhashable
7061 under the stricter __hash__ inheritance rules in 3.0. Several types
7062 which did not meet the rules for hash invariants and were already
7063 unhashable in 3.0 have now been explicitly flagged as unhashable in
7064 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7065 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7066
Brett Cannon88f801d2008-08-18 00:46:22 +00007067- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7068 imported into the module but exposed as part of the module's API.
7069
Brett Cannon7b96f072008-08-18 00:41:11 +00007070- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7071
Brett Cannon46225e72008-08-18 00:36:52 +00007072- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007074- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7075
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007076- Issue #3575: Incremental decoder's decode function now takes bytearray
7077 by using 's*' instead of 't#'.
7078
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007079- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007080 fails unicode conversion on 2nd parameter. (windows only)
7081
Georg Brandl222e2082010-08-01 22:27:39 +00007082- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007083 in a redirect.
7084
Brett Cannonabe423e2008-08-16 21:47:07 +00007085- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007086 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007087
Facundo Batistaeb90b782008-08-16 14:44:07 +00007088- Issue #2776: fixed small issue when handling an URL with double slash
7089 after a 302 response in the case of not going through a proxy.
7090
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007091- Issue #2676: in the email package, content-type parsing was hanging on
7092 pathological input because of quadratic or exponential behaviour of a
7093 regular expression.
7094
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007095- Issue #3476: binary buffered reading through the new "io" library is now
7096 thread-safe.
7097
Brett Cannonbf3157b2008-08-14 05:00:03 +00007098- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7099 since mimetools itself is deprecated. Because modules are cached, all
7100 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7101
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007102- Issue #3134: shutil referenced undefined WindowsError symbol.
7103
Robert Schuppenies14646332008-08-10 11:01:53 +00007104- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7105 menu entries were not deleted.
7106
Brett Cannon83e81842008-08-09 23:30:55 +00007107- Copied the implementation of reduce() to _functools.reduce() to have a
7108 version that did not raise a DeprecationWarning under -3.
7109
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007110- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7111 a MemoryError rather than silently stop the iteration.
7112
Guido van Rossum59ce9012008-08-09 14:55:34 +00007113- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7114 to _sre.compile() will now be rejected. This should not affect anybody
7115 since the re.compile() function never generates invalid re-bytecode.

7194
Georg Brandl3e483f62008-07-16 22:57:41 +00007195- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7196 its methods now allow for items objects that can be converted to
7197 an integer using operator.index().
7198
Mark Dickinson64b7e502008-07-16 09:40:03 +00007199- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7200 produced a ValueError instead of giving the correct float.
7201
Eric Smitha5fa5a22008-07-16 00:11:49 +00007202- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7203 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.

Mark Dickinson7103aa42008-07-15 19:08:33 +00007205- Issue #3008: the float type has a new instance method 'float.hex'
7206 and a new class method 'float.fromhex' to convert floating-point
7207 numbers to and from hexadecimal strings, respectively.
7208
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007209- Issue #2235: __hash__ is once again inherited by default. To allow
7210 collections.Hashable to remain meaningful in the presence of the
7211 default hash implementation (object.__hash__), it is now possible
7212 to explicit block inheritance of hash by setting __hash__=None at
7213 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7214 level.

7217 the parent module cannot be found while performing an absolute import.
7218 This means that an incorrectly defined __package__ attribute will
7219 now only prevent relative imports in that module rather than causing
7220 all imports from that module to fail.
7221
Nick Coghlan14ff9942008-07-08 14:21:42 +00007222- Issue #2517: Allow unicode messages in Exceptions again by correctly

7232 another thread's dictionary.
7233
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007234- Issue #3004: Minor change to slice.indices(): the start and stop
7235 arguments are now treated identically, making the behaviour easier
7236 to describe and understand. For example, slice(None, -10,
7237 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7238 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7239 10, -1).

7282 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007283 wrong because the actual transmitted size could differ from the

7686
Brett Cannonb61d8012008-05-11 23:39:04 +00007687- ``Lib/lib-old`` is now added to sys.path.
7688
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007689- On MacOS X it is now possible to install the framework in 64-bit
7690 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007691 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007692
7693 This is controlled by the configure argument ``--with-universal-archs``:
7694
7695 - ``--with-universal-archs=all``: install 4-way universal
7696
7697 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7698
7699 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7700
7701 This option should be used in combination with ``--enable-universalsdk=``.
7702
7703 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 +00007711
7712- The PyString functions have been renamed to PyBytes. A batch of
7713 defines were added so that the linker still sees the original
7714 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007752- Issue #1631171: Re-implement the 'warnings' module in C (the
7753 original Python code has been kept as backup). This will allow for
7754 using the 'warning's machinery in such places as the parser where
7755 use of pure Python code is not possible. Both the ``showarning()``
7756 and ``formatwarning()`` gain an optional 'line' argument which is
7757 not called by default for backwards-compatibility reasons. Setting
7758 ``warnings.showwarning()`` to an implementation that lacks support
7759 for the ``line`` argument will raise a DeprecationWarning.

7783
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007784- The getpass module has been improved on Unix. It now uses /dev/tty
7785 by default and uses stderr instead of stdout. A GetPassWarning is
7786 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007801- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007802 extension modules between 32 and 64 bit platforms. See the distutls

7807 file.close() is called while an object is in use by another thread
7808 an IOError exception will be raised and the file will not be closed.
7809
Thomas Hellerf7906482008-04-04 19:43:25 +00007810- The bundled libffi copy is now in sync with the recently released

7815 so the controlled environment will more closely mirror the typical
7816 script environment. This supports setup.py scripts that refer to
7817 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007822- Issue #2550: The approach used by client/server code for obtaining
7823 ports to listen on in network-oriented tests has been refined in an
7824 effort to facilitate running multiple instances of the entire
7825 regression test suite in parallel without issue.
7826 test_support.bind_port() has been fixed such that it will always
7827 return a unique port -- which wasn't always the case with the
7828 previous implementation, especially if socket options had been set
7829 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7830 new implementation of bind_port() will actually raise an exception
7831 if it is passed an AF_INET/SOCK_STREAM socket with either the
7832 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7833 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7834 the socket it's been passed. This currently only applies to
7835 Windows. This option prevents any other sockets from binding to the
7836 host/port we've bound to, thus removing the possibility of the
7837 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7838 when a second SOCK_STREAM socket binds and accepts to a host/port
7839 that's already been bound by another socket. The optional preferred
7840 port parameter to bind_port() has been removed. Under no
7841 circumstances should tests be hard coding ports!
7842
7843 test_support.find_unused_port() has also been introduced, which will
7844 pass a temporary socket object to bind_port() in order to obtain an
7845 unused port. The temporary socket object is then closed and
7846 deleted, and the port is returned. This method should only be used
7847 for obtaining an unused port in order to pass to an external program
7848 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7849 a parameter to a server-oriented class that doesn't give you direct
7850 access to the underlying socket used.
7851
7852 Finally, test_support.HOST has been introduced, which should be used
7853 for the host argument of any relevant socket calls (i.e. bind and
7854 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007855
7856 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007857 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007858 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7859 test_asynchat and test_socket_ssl.
7860
Georg Brandl3ee81df2008-05-17 18:14:43 +00007861 It is now possible for multiple instances of the regression test
7862 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008141- Added the future_builtins module, which contains hex() and oct().
8142 These are the PEP 3127 version of these functions, designed to be
8143 compatible with the hex() and oct() builtins from Python 3.0. They
8144 differ slightly in their output formats from the existing, unchanged
8145 Python 2.6 builtins. The expected usage of the future_builtins
8146 module is:
8147 from future_builtins import hex, oct
8148
Eric Smith7ef40bf2008-02-20 23:34:22 +00008149- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8150 exponents for exponents with absolute value < 100. Follows C99
8151 standard. This is a change on Windows, which would use 3 digits.
8152 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8153 so that any alterations it does to the resulting string will be
8154 available in stringlib/formatter.h (for float.__format__).
8155
Eric Smith5a3c1352008-02-19 13:21:56 +00008156- Implemented PEP 3101, Advanced String Formatting. This adds a new
8157 builtin format(); a format() method for str and unicode; a
8158 __format__() method to object, str, unicode, int, long, float, and
8159 datetime; the class string.Formatter; and the C API
8160 PyObject_Format().
8161
Georg Brandl3ee81df2008-05-17 18:14:43 +00008162- Fixed several potential crashes, all caused by specially crafted
8163 __del__ methods exploiting objects in temporarily inconsistent
8164 state.

8175 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008176
Georg Brandl3ee81df2008-05-17 18:14:43 +00008177- Issue #2045: Fix an infinite recursion triggered when printing a
8178 subclass of collections.defaultdict, if its default_factory is set
8179 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008180
Christian Heimesf75dbef2008-02-08 00:11:31 +00008181- Fixed a minor memory leak in dictobject.c. The content of the free
8182 list was not freed on interpreter shutdown.
8183
Georg Brandl21e99f42010-03-07 15:23:59 +00008184- Limit free list of method and built-in function objects to 256

8188 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008189 to compact the internal free lists of pre-allocted ints and floats.
8190
Georg Brandl3ee81df2008-05-17 18:14:43 +00008191- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8192 calls. Python expected the return type int but the fork familie
8193 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008201- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8202 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008203
Georg Brandl3ee81df2008-05-17 18:14:43 +00008204- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8205 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008206
Georg Brandl3ee81df2008-05-17 18:14:43 +00008207- Patch #1473257: generator objects gain a gi_code attribute. This is
8208 the same object as the func_code attribute of the function that
8209 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008210
Georg Brandl3ee81df2008-05-17 18:14:43 +00008211- Issue #1920: "while 0" statements were completely removed by the
8212 compiler, even in the presence of an "else" clause, which is
8213 supposed to be run when the condition is false. Now the compiler
8214 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008215
Guido van Rossumeead05f2008-01-24 18:21:02 +00008216- A few crashers fixed: weakref_in_del.py (issue #1377858);
8217 loosing_dict_ref.py (issue #1303614, test67.py);
8218 borrowed_ref_[34].py (not in tracker).
8219
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008220- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008221 suppressed while an extension is loaded by calling SetErrorMode in
8222 dynload_win.c. The error is still reported properly.
8223
Georg Brandl3ee81df2008-05-17 18:14:43 +00008224- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008225 several extension methods and modules do not work without unicode
8226 support.
8227
Georg Brandl26543b12008-01-21 18:36:51 +00008228- Issue #1882: when compiling code from a string, encoding cookies in the
8229 second line of code were not always recognized correctly.
8230
Georg Brandl14404b62008-01-19 19:27:05 +00008231- Issue #1679: "0x" was taken as a valid integer literal.
8232
Georg Brandl6caad7d2008-01-26 14:19:22 +00008233- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008234 added.
8235
Christian Heimesc94e2b52008-01-14 04:13:37 +00008236- sys.float_info / PyFloat_GetInfo: The floating point information
8237 object was converted from a dict to a specialized structseq object.
8238
Georg Brandl3ee81df2008-05-17 18:14:43 +00008239- Patch #1816: Added sys.flags structseq. It exposes the status of
8240 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008241
Georg Brandl3ee81df2008-05-17 18:14:43 +00008242- Objects/structseq.c: Implemented new structseq representation. The
8243 patch makes structseqs (e.g. the return value of os.stat) more
8244 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008245
Georg Brandl3ee81df2008-05-17 18:14:43 +00008246- Patch #1700288: added a type attribute cache that caches method
8247 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008248
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008249- Bug #1776: __import__() no longer accepts filenames on any platform.
8250 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008251
Georg Brandlaed6c662008-01-07 17:25:53 +00008252- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8253
Georg Brandl3ee81df2008-05-17 18:14:43 +00008254- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8255 envvar and sys.dont_write_bytecode attribute. All these can be set
8256 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008257
Georg Brandl3ee81df2008-05-17 18:14:43 +00008258- Improve some exception messages when Windows fails to load an
8259 extension module. Now we get for example '%1 is not a valid Win32
8260 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008261
Georg Brandl3ee81df2008-05-17 18:14:43 +00008262- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008264- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8265 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008266
Christian Heimes0a8143f2007-12-18 23:22:54 +00008267- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008268 and INF. float("nan"), float("inf") and float("-inf") now work on
8269 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008270
Georg Brandl3ee81df2008-05-17 18:14:43 +00008271- Compiler now generates simpler and faster code for dictionary
8272 literals. The oparg for BUILD_MAP now indicates an estimated
8273 dictionary size. There is a new opcode, STORE_MAP, for adding
8274 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008275
Georg Brandl3ee81df2008-05-17 18:14:43 +00008276- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008278- Issue #1620: New property decorator syntax was modifying the
8279 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00008280
Georg Brandl3ee81df2008-05-17 18:14:43 +00008281- Issue #1538: Avoid copying string in split/rsplit if the split char
8282 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008283
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008284- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008285 SystemError.
8286
Nick Coghlanef01d822007-12-03 12:55:17 +00008287- PEP 366: Allow explicit relative imports when executing modules
8288 inside packages with the -m switch via a new module level
8289 __package__ attribute.
8290
Georg Brandl3ee81df2008-05-17 18:14:43 +00008291- Issue #1402: Fix a crash on exit, when another thread is still
8292 running, and if the deallocation of its frames somehow calls the
8293 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008294

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008298 attribute of an empty cell object.
8299
Georg Brandl3ee81df2008-05-17 18:14:43 +00008300- Issue #1460: The utf-7 incremental decoder did not accept truncated
8301 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008302
Georg Brandl3ee81df2008-05-17 18:14:43 +00008303- Patch #1739468: Directories and zipfiles containing a __main__.py
8304 file can now be directly executed by passing their name to the
8305 interpreter. The directory/zipfile is automatically inserted as the
8306 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008307
Georg Brandl3ee81df2008-05-17 18:14:43 +00008308- Issue #1265: Fix a problem with sys.settrace, if the tracing
8309 function uses a generator expression when at the same time the
8310 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008311
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008312- sets and frozensets now have an isdisjoint() method.
8313
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008314- optimize the performance of builtin.sum().
8315
Neal Norwitz44f326e2007-10-05 05:29:17 +00008316- Fix warnings found by the new version of the Coverity checker.
8317
Georg Brandl21e99f42010-03-07 15:23:59 +00008318- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008319 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8320 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008321
Georg Brandl3ee81df2008-05-17 18:14:43 +00008322- Issue #1686386: Tuple's tp_repr did not take into account the
8323 possibility of having a self-referential tuple, which is possible
8324 from C code. Nor did object's tp_str consider that a type's tp_str
8325 could do something that could lead to an inifinite recursion.
8326 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8327 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008328
Georg Brandl3ee81df2008-05-17 18:14:43 +00008329- Issue #1164: It was possible to trigger deadlock when using the
8330 'print' statement to write to a file since the GIL was not released
8331 as needed. Now PyObject_Print() does the right thing along with
8332 various tp_print implementations of the built-in types and those in
8333 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008334
Georg Brandl3ee81df2008-05-17 18:14:43 +00008335- Issue #1147: Exceptions were directly allowing string exceptions in
8336 their throw() method even though string exceptions no longer
8337 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008338
Georg Brandl3ee81df2008-05-17 18:14:43 +00008339- Issue #1096: Prevent a segfault from getting the repr of a very
8340 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008341
Brett Cannon1e534b52007-09-07 04:18:30 +00008342- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008343 PyObject_Call() never calling back out to Python code to trigger
8344 recursion depth updates/checks. Required the creation of a static
8345 RuntimeError instance in case normalizing an exception put the
8346 recursion check value past its limit. Fixes crashers
8347 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008348
Georg Brandl3ee81df2008-05-17 18:14:43 +00008349- Patch #1031213: Decode source line in SyntaxErrors back to its
8350 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00008352- Patch #1673759: add a missing overflow check when formatting floats
8353 with %G.
8354
Georg Brandl3ee81df2008-05-17 18:14:43 +00008355- Prevent expandtabs() on string and unicode objects from causing a
8356 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00008357

Georg Brandla5ea6892007-06-01 11:33:33 +00008361
Neal Norwitz0ac60192007-05-27 04:08:54 +00008362- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008363 __*__ attributes. (Some already existed, e.g., __doc__ and
8364 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008365
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008366- Add -3 option to the interpreter to warn about features that are
8367 deprecated and will be changed/removed in Python 3.0.
8368
Georg Brandl2134e752007-05-21 20:34:16 +00008369- Patch #1686487: you can now pass any mapping after '**' in function
8370 calls.
8371
Collin Winter62903052007-05-18 23:11:24 +00008372- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008373 "except E as target:". This is to provide forwards compatibility
8374 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008375
Brett Cannon229cee22007-05-05 01:34:02 +00008376- Deprecate BaseException.message as per PEP 352.
8377
Georg Brandl3ee81df2008-05-17 18:14:43 +00008378- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008379 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008380
Vinay Sajip8549ce32007-05-06 17:53:37 +00008381- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008382 setting a plain string, ie don't expand to single letter identifiers.
8383
Raymond Hettinger13936692007-04-11 18:40:58 +00008384- Request #1191699: Slices can now be pickled.
8385
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008386- Request #1193128: str.translate() now allows a None argument for
8387 translations that only remove characters without re-mapping the
8388 remaining characters.
8389
Georg Brandl5cb76c12007-03-21 09:00:39 +00008390- Patch #1682205: a TypeError while unpacking an iterable is no longer
8391 masked by a generic one with the message "unpack non-sequence".
8392
Neal Norwitzaa754b72007-03-21 06:39:48 +00008393- Remove unused file Python/fmod.c.
8394
Guido van Rossum143b5642007-03-23 04:58:42 +00008395- Bug #1683368: The object.__init__() and object.__new__() methods are
8396 now stricter in rejecting excess arguments. The only time when
8397 either allows excess arguments is when it is not overridden and the
8398 other one is. For backwards compatibility, when both are
8399 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008400 warning later). Also, type.__init__() insists on the same signature
8401 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008402
Georg Brandl3ee81df2008-05-17 18:14:43 +00008403- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8404 object to complex using its __complex__() method before falling back
8405 to the __float__() method. Therefore, the functions in the cmath
8406 module now can operate on objects that define a __complex__()
8407 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008408
Georg Brandl3ee81df2008-05-17 18:14:43 +00008409- Patch #1623563: allow __class__ assignment for classes with
8410 __slots__. The old and the new class are still required to have the
8411 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008412
Georg Brandl3ee81df2008-05-17 18:14:43 +00008413- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00008416- Patch #1462488: Python no longer segfaults when
8417 ``object.__reduce_ex__()`` is called with an object that is faking
8418 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008419
Georg Brandl3ee81df2008-05-17 18:14:43 +00008420- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00008423- Patch #1444529: the builtin compile() now accepts keyword arguments.
8424
Georg Brandl7b9c5552007-03-12 14:30:05 +00008425- Bug #1678647: write a newline after printing an exception in any
8426 case, even when converting the value to a string failed.
8427
Georg Brandl871f1bc2007-03-12 13:17:36 +00008428- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008429 its argument, if it exists. If not, it will work like before. This
8430 allows customizing the output of dir() in the presence of a
8431 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008432
Collin Winter276887b2007-03-12 16:11:39 +00008433- Patch #922167: Python no longer segfaults when faced with infinitely
8434 self-recursive reload() calls (as reported by bug #742342).
8435
Georg Brandl3ee81df2008-05-17 18:14:43 +00008436- Patch #1675981: remove unreachable code from ``type.__new__()``
8437 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00008438
Georg Brandl3ee81df2008-05-17 18:14:43 +00008439- Patch #1491866: change the complex() constructor to allow

8951 ".cpp" too.
8952
Facundo Batistad918a652007-04-24 13:54:38 +00008953- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008954 the client's request was successfully received, understood, and
8955 accepted. Now in these cases no error is raised in urllib (issue
8956 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008957

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008964- Added a timeout parameter to the constructor of other protocols
8965 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8966 work started with create_connection() and timeout in httplib, and
8967 closes patch #723312.
8968
Vinay Sajip8549ce32007-05-06 17:53:37 +00008969- Patch #1676823: Added create_connection() to socket.py, which may be
8970 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008971 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008972
Martin v. Löwis0af33882007-03-23 13:27:15 +00008973- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008980- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
8981 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00008982 directories.
8983

8993
Georg Brandlf66b6032007-03-14 08:27:52 +00008994- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008995 AttributeError instead of an IOError when the server's response
8996 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008997
Georg Brandl3ee81df2008-05-17 18:14:43 +00008998- Patch #957650: "%var%" environment variable references are now
8999 properly expanded in ntpath.expandvars(), also "~user" home
9000 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00009001
Georg Brandl3ee81df2008-05-17 18:14:43 +00009002- Patch #1429539: pdb now correctly initializes the __main__ module
9003 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009004 correctly now.
9005
Georg Brandlbad6f192007-03-13 21:32:56 +00009006- The nonobvious commands.getstatus() function is now deprecated.

9012
Georg Brandl3ee81df2008-05-17 18:14:43 +00009013- Patch #1530482: add pydoc.render_doc() which returns the
9014 documentation for a thing instead of paging it to stdout, which
9015 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00009016
Georg Brandl3ee81df2008-05-17 18:14:43 +00009017- Patch #1533909: the timeit module now accepts callables in addition

9024 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00009026- Patch #1581073: add a flag to textwrap that prevents the dropping of
9027 whitespace while wrapping.
9028
Georg Brandl92a6bae2007-03-13 17:43:32 +00009029- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009030 are set for invalid interpolation sequences that would lead to
9031 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00009032

9045
Georg Brandl94fe3f52007-03-13 09:32:11 +00009046- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00009047 field names in its exception message if you try to write a record
9048 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00009066

9074 returned string up to the first NUL character.

9085
Georg Brandl3ee81df2008-05-17 18:14:43 +00009086- unittest now verifies more of its assumptions. In particular,
9087 TestCase and TestSuite subclasses (not instances) are no longer
9088 accepted in TestSuite.addTest(). This should cause no
9089 incompatibility since it never made sense with ordinary subclasses
9090 -- the failure just occurred later, with a more cumbersome
9091 exception.

9100 given a unicode argument and os.listdir() returns unicode filenames.
9101
Georg Brandl3ee81df2008-05-17 18:14:43 +00009102- Patch #1673619: setup.py identifies extension modules it doesn't

9456 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9457 silently miscode subclasses of those types. Now, it raises a
9458 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009459

Georg Brandl3ee81df2008-05-17 18:14:43 +00009474 time so that opening a database previously created with the DB_DUP
9475 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9476 opens. Specifically: dictionary assignment to a DB object will
9477 replace all values for a given key when the database allows
9478 duplicate values. DB users should use DB.put(k, v) when they want
9479 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009480

9486 characters with ASCII value less than 32. Also, it correctly quotes
9487 dots only if they occur on a single line, as opposed to the previous
9488 behavior of quoting dots if they are the second character of any
9489 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009490
