1347 32-bit-only installer Pythons on systems with Xcode 4 (currently
1348 OS X 10.8, 10.7, and optionally 10.6).
1349 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1350 * Since Xcode 4 removes ppc support, extension module builds now
1351 check for ppc compiler support and by default remove ppc and
1352 ppc64 archs when they are not available.
1353 * Extension module builds now revert to using system installed
1354 headers and libs (/usr and /System/Library) if the SDK used
1355 to build the interpreter is not installed or has moved.
1356 * Try to avoid building extension modules with deprecated
1357 and problematic Apple llvm-gcc compiler. If original compiler
1358 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001782- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001783 has left two versions of customize_compiler, the original in
1784 distutils.sysconfig and another copy in distutils.ccompiler, with some
1785 parts of distutils calling one and others using the other.
1786 Complete the revert back to only having one in distutils.sysconfig as
1787 is the case in 3.x.
1788
Ned Deily0d0ea482012-02-10 12:59:06 +01001789- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1790 Distutils-based packages with C extension modules may fail because
1791 Apple has removed gcc-4.2, the version used to build python.org
1792 64-bit/32-bit Pythons. If the user does not explicitly override
1793 the default C compiler by setting the CC environment variable,
1794 Distutils will now attempt to compile extension modules with clang
1795 if gcc-4.2 is required but not found. Also as a convenience, if
1796 the user does explicitly set CC, substitute its value as the default
1797 compiler in the Distutils LDSHARED configuration variable for OS X.
1798 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1799 SDK, neither of which are available in Xcode 4. This change does not
1800 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002050- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2051 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2052 interpreter process. This could cause failures in non-Distutils subprocesses
2053 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002054 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002055 deployment target only in the environment of each build subprocess. It is
2056 still possible to globally override the default by setting
2057 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2058 greater or equal to the default value, the value with which the interpreter
2059 was built.

2089 the ticker doesn't have to wind down to zero from the old starting point
2090 before the new interval takes effect. And if the user increases the
2091 interval, it makes sure the new limit takes effect right away rather have an
2092 early task switch before recognizing the new interval.

3073 This prevents user-created self-referencing ordered dictionaries from
3074 becoming permanently uncollectable GC garbage. The downside is that

3534
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003535- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3536 start byte and the continuation byte(s) are now considered invalid, instead
3537 of the number of bytes specified by the start byte.
3538 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3539 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3540 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3541 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003543- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003544 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3545 arises from the "Overriding __eq__ blocks inheritance ..." warning
3546 when turned into an exception: in this case the exception simply
3547 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003549- Issue #8748: Fix two issues with comparisons between complex and integer
3550 objects. (1) The comparison could incorrectly return True in some cases
3551 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3552 (2) The comparison raised an OverflowError for large integers, leading
3553 to unpredictable exceptions when combining integers and complex objects
3554 in sets or dicts.
3555
Mark Dickinson81336372010-05-30 12:12:25 +00003556- Issue #5211: Implicit coercion for the complex type is now completely
3557 removed. (Coercion for arithmetic operations was already removed in 2.7
3558 alpha 4, but coercion for rich comparisons was accidentally left in.)
3559
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003560- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

3562
Georg Brandlfee0f442010-05-22 21:26:21 +00003563- Issue #7902: When using explicit relative import syntax, don't try implicit

3924 changed.

3937 with a non-empty format string. This is an effort to future-proof user
3938 code. If a derived class does not currently implement __format__ but later
3939 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003940 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003941 Python 3.3 and it will be an error in Python 3.4.

3992 InvalidOperation instead of returning False. (Comparisons involving a quiet
3993 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3994 signaling NaNs remain unhashable.

4003 read on demand and the named file is compiled immediately. (Original patch by

4015 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4016 <=> complex, and complex <=> complex comparisons.

4379 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4380 returning NULL. The macro now returns a statically allocated empty string

4391 strings,
4392 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4393 numeric strings corresponding to subnormal values,
4394 (3) a memory leak for some values large enough to cause overflow, and
4395 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00004426- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004427 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004428 Also, raise ValueError rather than TypeError when an unknown TIPC address
4429 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004433- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004434 file position when calling `truncate()`. It would previously change the file
4435 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004436 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4437
Georg Brandlba83f822010-03-14 09:50:54 +00004438- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4439 class used to represent files stored inside an archive. The new
4440 implementation is significantly faster and can be wrapped in a
4441 ``io.BufferedReader`` object for more speedups. It also solves an issue
4442 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4443 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004453- Issue #7748: Since unicode values are supported for some metadata options in

4531-----------------
4532
Georg Brandlba83f822010-03-14 09:50:54 +00004533- The ``__complex__()`` method is now looked up on the class of instances to
4534 make it consistent with other special methods.

4538
Mark Dickinson1b34d252010-01-01 17:27:30 +00004539- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004540 DeprecationWarning when passed a float argument where an integer was expected.
4541 These functions and methods now raise TypeError instead. The majority of the
4542 effects of this change are in the extension modules, but some core functions
4543 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4544 and many unicode/str methods.

4558 of integers: the result of a/b is now correctly rounded for ints a and b (at
4559 least on IEEE 754 platforms), and in particular does not depend on the
4560 internal representation of a long.

4568
Georg Brandlba83f822010-03-14 09:50:54 +00004569 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004705- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
4706 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004707
Georg Brandlba83f822010-03-14 09:50:54 +00004708- Issue #3382: 'F' formatting for float and complex now convert the result to
4709 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4710 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004711
Georg Brandlba83f822010-03-14 09:50:54 +00004712- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4713 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004714
Georg Brandlba83f822010-03-14 09:50:54 +00004715- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4716 1e-100 used to raise OverflowError, but now gives the requested 120
4717 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004718
Georg Brandlba83f822010-03-14 09:50:54 +00004719- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00004720
Georg Brandlba83f822010-03-14 09:50:54 +00004721- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00004722
Georg Brandlba83f822010-03-14 09:50:54 +00004723- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
4724 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004725
Georg Brandlba83f822010-03-14 09:50:54 +00004726- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4727 decimal string that's guaranteed to round back to x under correct rounding
4728 (with round-half-to-even rounding mode). Previously it gave a string based on
4729 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4730 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4731 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004732
Georg Brandlba83f822010-03-14 09:50:54 +00004733- Issue #7117: On almost all platforms: float-to-string and string-to-float
4734 conversions within Python are now correctly rounded. Places these conversions
4735 occur include: str for floats and complex numbers; the float and complex
4736 constructors; old-style and new-style numeric formatting; serialization and
4737 deserialization of floats and complex numbers using marshal, pickle and json;
4738 parsing of float and imaginary literals in Python code; Decimal-to-float
4739 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004740
Georg Brandlba83f822010-03-14 09:50:54 +00004741 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4742 providing correctly-rounded strtod and dtoa C functions. This code is
4743 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4744 the C compiler. There may be a small number of platforms on which correct
4745 operation of this code cannot be guaranteed, so the code is not used: notably,
4746 this applies to platforms where the C double format is not IEEE 754 binary64,
4747 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4748 and Python's configure script is unable to determine how to change the FPU
4749 precision. On these platforms conversions use the platform strtod and dtoa,
4750 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004751
Georg Brandlba83f822010-03-14 09:50:54 +00004752- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4753 uses the correctly-rounded string <-> float conversions described above (when
4754 available), and so produces correctly rounded results that will display nicely
4755 under the float repr. There are two related small changes: (1) round now
4756 accepts any class with an ``__index__()`` method for its second argument (but
4757 no longer accepts floats for the second argument), and (2) an excessively
4758 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4759 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00004760
Philip Jenveyfab8be22009-11-17 02:42:26 +00004761- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
4762
Georg Brandlba83f822010-03-14 09:50:54 +00004763- Fix several issues with ``compile()``. The input can now contain Windows and
4764 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00004765
Georg Brandlba83f822010-03-14 09:50:54 +00004766- Remove length limitation when constructing a complex number from a unicode
4767 string.
Mark Dickinsonc04c7c52009-10-26 22:28:14 +00004768
Georg Brandlba83f822010-03-14 09:50:54 +00004769- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
4770 during the formation of an output tuple.
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +00004771
Mark Dickinson8d87dc02009-10-25 20:39:06 +00004772- Issue #1087418: Boost performance of bitwise operations for longs.
4773
Georg Brandlba83f822010-03-14 09:50:54 +00004774- Issue #1722344: ``threading._shutdown()`` is now called in ``Py_Finalize()``,
4775 which fixes the problem of some exceptions being thrown at shutdown when the
4776 interpreter is killed. Patch by Adam Olsen.
Antoine Pitrouefb60c02009-10-20 21:29:37 +00004777
Georg Brandlba83f822010-03-14 09:50:54 +00004778- Issue #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``,
4779 and note that they are unsafe and deprecated.
Eric Smithc12781a2009-10-19 14:38:14 +00004780
Georg Brandlba83f822010-03-14 09:50:54 +00004781- Issue #7120: logging: Remove import of multiprocessing which is causing crash
4782 in GAE.
Vinay Sajip03d5c342009-10-16 14:06:44 +00004783
Georg Brandlba83f822010-03-14 09:50:54 +00004784- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
4785 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +00004786
Georg Brandlba83f822010-03-14 09:50:54 +00004787- Issue #1754094: Improve the stack depth calculation in the compiler. There
4788 should be no other effect than a small decrease in memory use. Patch by
4789 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00004790
Georg Brandlba83f822010-03-14 09:50:54 +00004791- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
4792 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +00004793
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00004794- Issue #1571184: The Unicode database contains properties for more characters.
4795 The tables for code points representing numeric values, white spaces or line
4796 breaks are now generated from the official Unicode Character Database files,
4797 and include information from the Unihan.txt file.

4803 running through the shell. Patch by Jean-Paul Calderone and Jani Hakala.
Philip Jenvey8b902042009-09-29 19:10:15 +00004804
Georg Brandlba83f822010-03-14 09:50:54 +00004805- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004901
Georg Brandlba83f822010-03-14 09:50:54 +00004902 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4903 (2) parsing of strings representing infinities and nans was locale aware; and
4904 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004906- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4907 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4908 but with at least one decimal point and with a default precision
4909 of 12. Previously, the behavior the same but with a default precision of 6.
4910 This more closely matches ``str()``, and reduces surprises when adding
4911 alignment flags to the empty presentation type. This also affects the new
4912 complex.__format__ in the same way.
4913
4914- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4915 classtype's, even if it was None. property now inserts the __doc__ into the

Walter Dörwalded960ac2009-05-03 22:36:33 +00005164- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5165 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

5174 gives improved memory leak detection when running under Valgrind, while taking
5175 advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006545- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6546 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6547 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6548 ``printf`` function, whereas PyString_FromFormat has an independent
6549 implementation and uses "%zd" on all platforms for size_t values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006553- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6554 error.
6555
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006556- Issue #3777: long() applied to a float object now always return a long
6557 object; previously an int would be returned for small values. the __long__
6558 method is allowed to return either an int or a long, but the behaviour of
6559 float objects should not change to respect backward compatibility.
6560
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006561- Issue #3751: str.rpartition would perform a left-partition when called with
6562 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006566- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006567 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006568 was correctly parsed but parsing of subsequent arguments failed.
6569
Vinay Sajip35e3b032008-09-01 14:33:59 +00006570- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006571 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6572 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6573 when given a tuple of classes as second argument, were looking up
6574 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6575 type object.
6576
Neal Norwitz18aa3882008-08-24 05:04:52 +00006577- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006646 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6647 for catch_warnings() also led to an improvement in the raising of a
6648 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006714What's New in Python 2.6 beta 3?
6715================================
6716
Barry Warsaw07a4a382008-08-21 01:15:08 +00006717*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006718
6719Core and Builtins
6720-----------------
6721
Guido van Rossumf8402962008-08-20 15:01:50 +00006722- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6723 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6724 extensions do not automatically benefit from the class attribute
6725 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6726 to their tp_flags field if they care. This is a backwards
6727 compatibility feature; in 3.0, all types will use the cache by
6728 default.
6729
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006730- Keyword arguments can now follow starred arguments. (``f(a, *args,
6731 keyword=23)`` is now valid syntax.)
6732
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006733- ctypes function pointers that are COM methods have a boolean True
6734 value again.
6735
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006736- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6737 by denying s# to parse objects that have a releasebuffer procedure,
6738 and introducing s*.
6739
Georg Brandl1e13ea92008-08-11 09:07:59 +00006740- Issue #3537: Fix an assertion failure when an empty but presized dict
6741 object was stored in the freelist.
6742
Mark Dickinsonb6467572008-08-04 21:30:09 +00006743- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6744 ValueError consistently across platforms.
6745
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006746- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6747 (64bit Unix, for example), unichr() would truncate its argument and return
6748 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6749
Neal Norwitze7d8be82008-07-31 17:17:14 +00006750- Apply security patches from Apple.
6751
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006752- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6753 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6754
Antoine Pitrou92f82162008-07-25 22:22:08 +00006755- Issue #1819: function calls with several named parameters are now on
6756 average 35% faster (as measured by pybench).
6757
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006758- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6759 the python debugger steps into a class statement: the free variables (local
6760 variables defined in an outer scope) would be deleted from the outer scope.
6761
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006762- Issue #2620: Overflow checking when allocating or reallocating memory
6763 was not always being done properly in some python types and extension
6764 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6765 all been updated to perform better checks and places in the code that
6766 would previously leak memory on the error path when such an allocation
6767 failed have been fixed.

6770-------
6771
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006772- Issue #3612: Added some missing basic types in ctypes.wintypes.
6773
Benjamin Petersone977ad42008-08-20 01:42:01 +00006774- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6775 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6776
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006777- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6778 version reported by these tools does not necessarily follow the python
6779 version numbering scheme, so the module is less strict when parsing it.
6780
Nick Coghlanf70385a2008-08-18 12:42:46 +00006781- Issue #2235: Added Py3k warnings for types which will become unhashable
6782 under the stricter __hash__ inheritance rules in 3.0. Several types
6783 which did not meet the rules for hash invariants and were already
6784 unhashable in 3.0 have now been explicitly flagged as unhashable in
6785 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6786 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6787
Brett Cannon88f801d2008-08-18 00:46:22 +00006788- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6789 imported into the module but exposed as part of the module's API.
6790
Brett Cannon7b96f072008-08-18 00:41:11 +00006791- Remove an unneeded import of abc.ABCMeta from 'inspect'.

6796
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006797- Issue #3575: Incremental decoder's decode function now takes bytearray
6798 by using 's*' instead of 't#'.
6799
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006800- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006801 fails unicode conversion on 2nd parameter. (windows only)
6802
Georg Brandl222e2082010-08-01 22:27:39 +00006803- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006804 in a redirect.
6805
Brett Cannonabe423e2008-08-16 21:47:07 +00006806- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006807 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006808
Facundo Batistaeb90b782008-08-16 14:44:07 +00006809- Issue #2776: fixed small issue when handling an URL with double slash
6810 after a 302 response in the case of not going through a proxy.
6811
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006812- Issue #2676: in the email package, content-type parsing was hanging on
6813 pathological input because of quadratic or exponential behaviour of a
6814 regular expression.
6815
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006816- Issue #3476: binary buffered reading through the new "io" library is now
6817 thread-safe.
6818
Brett Cannonbf3157b2008-08-14 05:00:03 +00006819- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6820 since mimetools itself is deprecated. Because modules are cached, all
6821 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6822
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006823- Issue #3134: shutil referenced undefined WindowsError symbol.
6824
Robert Schuppenies14646332008-08-10 11:01:53 +00006825- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6826 menu entries were not deleted.
6827
Brett Cannon83e81842008-08-09 23:30:55 +00006828- Copied the implementation of reduce() to _functools.reduce() to have a
6829 version that did not raise a DeprecationWarning under -3.
6830
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006831- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6832 a MemoryError rather than silently stop the iteration.
6833
Guido van Rossum59ce9012008-08-09 14:55:34 +00006834- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6835 to _sre.compile() will now be rejected. This should not affect anybody
6836 since the re.compile() function never generates invalid re-bytecode.

6915
Georg Brandl3e483f62008-07-16 22:57:41 +00006916- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6917 its methods now allow for items objects that can be converted to
6918 an integer using operator.index().
6919
Mark Dickinson64b7e502008-07-16 09:40:03 +00006920- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6921 produced a ValueError instead of giving the correct float.
6922
Eric Smitha5fa5a22008-07-16 00:11:49 +00006923- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

6927 and a new class method 'float.fromhex' to convert floating-point
6928 numbers to and from hexadecimal strings, respectively.
6929
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006930- Issue #2235: __hash__ is once again inherited by default. To allow
6931 collections.Hashable to remain meaningful in the presence of the
6932 default hash implementation (object.__hash__), it is now possible
6933 to explicit block inheritance of hash by setting __hash__=None at
6934 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6935 level.

6938 the parent module cannot be found while performing an absolute import.
6939 This means that an incorrectly defined __package__ attribute will
6940 now only prevent relative imports in that module rather than causing
6941 all imports from that module to fail.

Nick Coghlan14ff9942008-07-08 14:21:42 +00006943- Issue #2517: Allow unicode messages in Exceptions again by correctly

6953 another thread's dictionary.
6954
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006955- Issue #3004: Minor change to slice.indices(): the start and stop
6956 arguments are now treated identically, making the behaviour easier
6957 to describe and understand. For example, slice(None, -10,
6958 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6959 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6960 10, -1).

7003 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007004 wrong because the actual transmitted size could differ from the

7407
Brett Cannonb61d8012008-05-11 23:39:04 +00007408- ``Lib/lib-old`` is now added to sys.path.
7409
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007410- On MacOS X it is now possible to install the framework in 64-bit
7411 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007412 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007413
7414 This is controlled by the configure argument ``--with-universal-archs``:
7415
7416 - ``--with-universal-archs=all``: install 4-way universal
7417
7418 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7419
7420 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7421
7422 This option should be used in combination with ``--enable-universalsdk=``.
7423
7424 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 +00007432
7433- The PyString functions have been renamed to PyBytes. A batch of
7434 defines were added so that the linker still sees the original
7435 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007473- Issue #1631171: Re-implement the 'warnings' module in C (the
7474 original Python code has been kept as backup). This will allow for
7475 using the 'warning's machinery in such places as the parser where
7476 use of pure Python code is not possible. Both the ``showarning()``
7477 and ``formatwarning()`` gain an optional 'line' argument which is
7478 not called by default for backwards-compatibility reasons. Setting
7479 ``warnings.showwarning()`` to an implementation that lacks support
7480 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007522- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007523 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007543- Issue #2550: The approach used by client/server code for obtaining
7544 ports to listen on in network-oriented tests has been refined in an
7545 effort to facilitate running multiple instances of the entire
7546 regression test suite in parallel without issue.
7547 test_support.bind_port() has been fixed such that it will always
7548 return a unique port -- which wasn't always the case with the
7549 previous implementation, especially if socket options had been set
7550 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7551 new implementation of bind_port() will actually raise an exception
7552 if it is passed an AF_INET/SOCK_STREAM socket with either the
7553 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7554 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7555 the socket it's been passed. This currently only applies to
7556 Windows. This option prevents any other sockets from binding to the
7557 host/port we've bound to, thus removing the possibility of the
7558 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7559 when a second SOCK_STREAM socket binds and accepts to a host/port
7560 that's already been bound by another socket. The optional preferred
7561 port parameter to bind_port() has been removed. Under no
7562 circumstances should tests be hard coding ports!
7563
7564 test_support.find_unused_port() has also been introduced, which will
7565 pass a temporary socket object to bind_port() in order to obtain an
7566 unused port. The temporary socket object is then closed and
7567 deleted, and the port is returned. This method should only be used
7568 for obtaining an unused port in order to pass to an external program
7569 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7570 a parameter to a server-oriented class that doesn't give you direct
7571 access to the underlying socket used.
7572
7573 Finally, test_support.HOST has been introduced, which should be used
7574 for the host argument of any relevant socket calls (i.e. bind and
7575 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007576
7577 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007578 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007579 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7580 test_asynchat and test_socket_ssl.
7581
Georg Brandl3ee81df2008-05-17 18:14:43 +00007582 It is now possible for multiple instances of the regression test
7583 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007862- Added the future_builtins module, which contains hex() and oct().
7863 These are the PEP 3127 version of these functions, designed to be
7864 compatible with the hex() and oct() builtins from Python 3.0. They
7865 differ slightly in their output formats from the existing, unchanged
7866 Python 2.6 builtins. The expected usage of the future_builtins
7867 module is:
7868 from future_builtins import hex, oct
7869
Eric Smith7ef40bf2008-02-20 23:34:22 +00007870- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7871 exponents for exponents with absolute value < 100. Follows C99
7872 standard. This is a change on Windows, which would use 3 digits.
7873 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7874 so that any alterations it does to the resulting string will be
7875 available in stringlib/formatter.h (for float.__format__).
7876
Eric Smith5a3c1352008-02-19 13:21:56 +00007877- Implemented PEP 3101, Advanced String Formatting. This adds a new
7878 builtin format(); a format() method for str and unicode; a
7879 __format__() method to object, str, unicode, int, long, float, and
7880 datetime; the class string.Formatter; and the C API
7881 PyObject_Format().
7882
Georg Brandl3ee81df2008-05-17 18:14:43 +00007883- Fixed several potential crashes, all caused by specially crafted
7884 __del__ methods exploiting objects in temporarily inconsistent
7885 state.

7896 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007897
Georg Brandl3ee81df2008-05-17 18:14:43 +00007898- Issue #2045: Fix an infinite recursion triggered when printing a
7899 subclass of collections.defaultdict, if its default_factory is set
7900 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007901
Christian Heimesf75dbef2008-02-08 00:11:31 +00007902- Fixed a minor memory leak in dictobject.c. The content of the free

7909 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007910 to compact the internal free lists of pre-allocted ints and floats.
7911
Georg Brandl3ee81df2008-05-17 18:14:43 +00007912- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7913 calls. Python expected the return type int but the fork familie
7914 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007922- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7923 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007924
Georg Brandl3ee81df2008-05-17 18:14:43 +00007925- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7926 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007927
Georg Brandl3ee81df2008-05-17 18:14:43 +00007928- Patch #1473257: generator objects gain a gi_code attribute. This is
7929 the same object as the func_code attribute of the function that
7930 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007931
Georg Brandl3ee81df2008-05-17 18:14:43 +00007932- Issue #1920: "while 0" statements were completely removed by the
7933 compiler, even in the presence of an "else" clause, which is
7934 supposed to be run when the condition is false. Now the compiler
7935 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007936
Guido van Rossumeead05f2008-01-24 18:21:02 +00007937- A few crashers fixed: weakref_in_del.py (issue #1377858);
7938 loosing_dict_ref.py (issue #1303614, test67.py);
7939 borrowed_ref_[34].py (not in tracker).
7940
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007941- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007942 suppressed while an extension is loaded by calling SetErrorMode in
7943 dynload_win.c. The error is still reported properly.
7944
Georg Brandl3ee81df2008-05-17 18:14:43 +00007945- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007946 several extension methods and modules do not work without unicode
7947 support.
7948
Georg Brandl26543b12008-01-21 18:36:51 +00007949- Issue #1882: when compiling code from a string, encoding cookies in the
7950 second line of code were not always recognized correctly.
7951
Georg Brandl14404b62008-01-19 19:27:05 +00007952- Issue #1679: "0x" was taken as a valid integer literal.
7953
Georg Brandl6caad7d2008-01-26 14:19:22 +00007954- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007955 added.
7956
Christian Heimesc94e2b52008-01-14 04:13:37 +00007957- sys.float_info / PyFloat_GetInfo: The floating point information
7958 object was converted from a dict to a specialized structseq object.
7959
Georg Brandl3ee81df2008-05-17 18:14:43 +00007960- Patch #1816: Added sys.flags structseq. It exposes the status of
7961 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007962
Georg Brandl3ee81df2008-05-17 18:14:43 +00007963- Objects/structseq.c: Implemented new structseq representation. The
7964 patch makes structseqs (e.g. the return value of os.stat) more
7965 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007966
Georg Brandl3ee81df2008-05-17 18:14:43 +00007967- Patch #1700288: added a type attribute cache that caches method
7968 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007969
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007970- Bug #1776: __import__() no longer accepts filenames on any platform.
7971 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007972
Georg Brandlaed6c662008-01-07 17:25:53 +00007973- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7974
Georg Brandl3ee81df2008-05-17 18:14:43 +00007975- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7976 envvar and sys.dont_write_bytecode attribute. All these can be set
7977 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007978
Georg Brandl3ee81df2008-05-17 18:14:43 +00007979- Improve some exception messages when Windows fails to load an
7980 extension module. Now we get for example '%1 is not a valid Win32
7981 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007982
Georg Brandl3ee81df2008-05-17 18:14:43 +00007983- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007985- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7986 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007987
Christian Heimes0a8143f2007-12-18 23:22:54 +00007988- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007989 and INF. float("nan"), float("inf") and float("-inf") now work on
7990 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007991
Georg Brandl3ee81df2008-05-17 18:14:43 +00007992- Compiler now generates simpler and faster code for dictionary
7993 literals. The oparg for BUILD_MAP now indicates an estimated
7994 dictionary size. There is a new opcode, STORE_MAP, for adding
7995 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007996
Georg Brandl3ee81df2008-05-17 18:14:43 +00007997- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008002- Issue #1538: Avoid copying string in split/rsplit if the split char
8003 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008004
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008005- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008006 SystemError.
8007
Nick Coghlanef01d822007-12-03 12:55:17 +00008008- PEP 366: Allow explicit relative imports when executing modules
8009 inside packages with the -m switch via a new module level
8010 __package__ attribute.
8011

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008019 attribute of an empty cell object.
8020
Georg Brandl3ee81df2008-05-17 18:14:43 +00008021- Issue #1460: The utf-7 incremental decoder did not accept truncated
8022 input. It now correctly saves its state between chunks of data.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008024- Patch #1739468: Directories and zipfiles containing a __main__.py
8025 file can now be directly executed by passing their name to the
8026 interpreter. The directory/zipfile is automatically inserted as the
8027 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008028
Georg Brandl3ee81df2008-05-17 18:14:43 +00008029- Issue #1265: Fix a problem with sys.settrace, if the tracing
8030 function uses a generator expression when at the same time the
8031 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008032
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008033- sets and frozensets now have an isdisjoint() method.
8034
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008035- optimize the performance of builtin.sum().
8036
Neal Norwitz44f326e2007-10-05 05:29:17 +00008037- Fix warnings found by the new version of the Coverity checker.
8038
Georg Brandl21e99f42010-03-07 15:23:59 +00008039- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008040 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8041 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008042
Georg Brandl3ee81df2008-05-17 18:14:43 +00008043- Issue #1686386: Tuple's tp_repr did not take into account the
8044 possibility of having a self-referential tuple, which is possible
8045 from C code. Nor did object's tp_str consider that a type's tp_str
8046 could do something that could lead to an inifinite recursion.
8047 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8048 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008049
Georg Brandl3ee81df2008-05-17 18:14:43 +00008050- Issue #1164: It was possible to trigger deadlock when using the
8051 'print' statement to write to a file since the GIL was not released
8052 as needed. Now PyObject_Print() does the right thing along with
8053 various tp_print implementations of the built-in types and those in
8054 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008055
Georg Brandl3ee81df2008-05-17 18:14:43 +00008056- Issue #1147: Exceptions were directly allowing string exceptions in
8057 their throw() method even though string exceptions no longer
8058 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008059
Georg Brandl3ee81df2008-05-17 18:14:43 +00008060- Issue #1096: Prevent a segfault from getting the repr of a very
8061 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008062
Brett Cannon1e534b52007-09-07 04:18:30 +00008063- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064 PyObject_Call() never calling back out to Python code to trigger
8065 recursion depth updates/checks. Required the creation of a static
8066 RuntimeError instance in case normalizing an exception put the
8067 recursion check value past its limit. Fixes crashers
8068 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008069
Georg Brandl3ee81df2008-05-17 18:14:43 +00008070- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008083- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008084 __*__ attributes. (Some already existed, e.g., __doc__ and
8085 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008086
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008087- Add -3 option to the interpreter to warn about features that are
8088 deprecated and will be changed/removed in Python 3.0.
8089
Georg Brandl2134e752007-05-21 20:34:16 +00008090- Patch #1686487: you can now pass any mapping after '**' in function
8091 calls.
8092
Collin Winter62903052007-05-18 23:11:24 +00008093- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008094 "except E as target:". This is to provide forwards compatibility
8095 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008096
Brett Cannon229cee22007-05-05 01:34:02 +00008097- Deprecate BaseException.message as per PEP 352.
8098
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008100 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008101
Vinay Sajip8549ce32007-05-06 17:53:37 +00008102- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008103 setting a plain string, ie don't expand to single letter identifiers.
8104
Raymond Hettinger13936692007-04-11 18:40:58 +00008105- Request #1191699: Slices can now be pickled.
8106
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008107- Request #1193128: str.translate() now allows a None argument for
8108 translations that only remove characters without re-mapping the
8109 remaining characters.
8110
Georg Brandl5cb76c12007-03-21 09:00:39 +00008111- Patch #1682205: a TypeError while unpacking an iterable is no longer
8112 masked by a generic one with the message "unpack non-sequence".
8113
Neal Norwitzaa754b72007-03-21 06:39:48 +00008114- Remove unused file Python/fmod.c.
8115
Guido van Rossum143b5642007-03-23 04:58:42 +00008116- Bug #1683368: The object.__init__() and object.__new__() methods are
8117 now stricter in rejecting excess arguments. The only time when
8118 either allows excess arguments is when it is not overridden and the
8119 other one is. For backwards compatibility, when both are
8120 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008121 warning later). Also, type.__init__() insists on the same signature
8122 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008123
Georg Brandl3ee81df2008-05-17 18:14:43 +00008124- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8125 object to complex using its __complex__() method before falling back
8126 to the __float__() method. Therefore, the functions in the cmath
8127 module now can operate on objects that define a __complex__()
8128 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008129
Georg Brandl3ee81df2008-05-17 18:14:43 +00008130- Patch #1623563: allow __class__ assignment for classes with
8131 __slots__. The old and the new class are still required to have the
8132 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008133
Georg Brandl3ee81df2008-05-17 18:14:43 +00008134- Patch #1642547: Fix an error/crash when encountering syntax errors

8138 ``object.__reduce_ex__()`` is called with an object that is faking
8139 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008140
Georg Brandl3ee81df2008-05-17 18:14:43 +00008141- Patch #1680015: Don't modify __slots__ tuple if it contains an

8145
Georg Brandl7b9c5552007-03-12 14:30:05 +00008146- Bug #1678647: write a newline after printing an exception in any
8147 case, even when converting the value to a string failed.
8148
Georg Brandl871f1bc2007-03-12 13:17:36 +00008149- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008150 its argument, if it exists. If not, it will work like before. This
8151 allows customizing the output of dir() in the presence of a
8152 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00008154- Patch #922167: Python no longer segfaults when faced with infinitely
8155 self-recursive reload() calls (as reported by bug #742342).
8156
Georg Brandl3ee81df2008-05-17 18:14:43 +00008157- Patch #1675981: remove unreachable code from ``type.__new__()``
8158 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00008159
Georg Brandl3ee81df2008-05-17 18:14:43 +00008160- Patch #1491866: change the complex() constructor to allow

8672 ".cpp" too.
8673
Facundo Batistad918a652007-04-24 13:54:38 +00008674- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008675 the client's request was successfully received, understood, and
8676 accepted. Now in these cases no error is raised in urllib (issue
8677 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00008678

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008685- Added a timeout parameter to the constructor of other protocols
8686 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8687 work started with create_connection() and timeout in httplib, and
8688 closes patch #723312.
8689
Vinay Sajip8549ce32007-05-06 17:53:37 +00008690- Patch #1676823: Added create_connection() to socket.py, which may be
8691 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008692 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008693
Martin v. Löwis0af33882007-03-23 13:27:15 +00008694- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008701- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
8702 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00008703 directories.
8704

8706 GNOME or KDE browser, depending on whether there is a session of one
8707 of those present. Also, it tries the Windows default browser before
8708 trying Mozilla variants.

8714
Georg Brandlf66b6032007-03-14 08:27:52 +00008715- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008716 AttributeError instead of an IOError when the server's response
8717 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008718
Georg Brandl3ee81df2008-05-17 18:14:43 +00008719- Patch #957650: "%var%" environment variable references are now
8720 properly expanded in ntpath.expandvars(), also "~user" home
8721 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00008722
Georg Brandl3ee81df2008-05-17 18:14:43 +00008723- Patch #1429539: pdb now correctly initializes the __main__ module
8724 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008725 correctly now.
8726
Georg Brandlbad6f192007-03-13 21:32:56 +00008727- The nonobvious commands.getstatus() function is now deprecated.

8733
Georg Brandl3ee81df2008-05-17 18:14:43 +00008734- Patch #1530482: add pydoc.render_doc() which returns the
8735 documentation for a thing instead of paging it to stdout, which
8736 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00008737
Georg Brandl3ee81df2008-05-17 18:14:43 +00008738- Patch #1533909: the timeit module now accepts callables in addition

8744 parameter which can be set to False to prevent the default
8745 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008746
Georg Brandl9e6b4702007-03-13 18:15:41 +00008747- Patch #1581073: add a flag to textwrap that prevents the dropping of
8748 whitespace while wrapping.
8749
Georg Brandl92a6bae2007-03-13 17:43:32 +00008750- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008751 are set for invalid interpolation sequences that would lead to
8752 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008753

8766
Georg Brandl94fe3f52007-03-13 09:32:11 +00008767- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00008768 field names in its exception message if you try to write a record
8769 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00008787

8795 returned string up to the first NUL character.
8796

8806
Georg Brandl3ee81df2008-05-17 18:14:43 +00008807- unittest now verifies more of its assumptions. In particular,
8808 TestCase and TestSuite subclasses (not instances) are no longer
8809 accepted in TestSuite.addTest(). This should cause no
8810 incompatibility since it never made sense with ordinary subclasses
8811 -- the failure just occurred later, with a more cumbersome
8812 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00008813

8821 given a unicode argument and os.listdir() returns unicode filenames.
8822
Georg Brandl3ee81df2008-05-17 18:14:43 +00008823- Patch #1673619: setup.py identifies extension modules it doesn't

9177 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9178 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009194- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009195 time so that opening a database previously created with the DB_DUP
9196 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9197 opens. Specifically: dictionary assignment to a DB object will
9198 replace all values for a given key when the database allows
9199 duplicate values. DB users should use DB.put(k, v) when they want
9200 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009201

9207 characters with ASCII value less than 32. Also, it correctly quotes
9208 dots only if they occur on a single line, as opposed to the previous
9209 behavior of quoting dots if they are the second character of any
9210 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009211
