1422 32-bit-only installer Pythons on systems with Xcode 4 (currently
1423 OS X 10.8, 10.7, and optionally 10.6).
1424 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1425 * Since Xcode 4 removes ppc support, extension module builds now
1426 check for ppc compiler support and by default remove ppc and
1427 ppc64 archs when they are not available.
1428 * Extension module builds now revert to using system installed
1429 headers and libs (/usr and /System/Library) if the SDK used
1430 to build the interpreter is not installed or has moved.
1431 * Try to avoid building extension modules with deprecated
1432 and problematic Apple llvm-gcc compiler. If original compiler
1433 is not available, use clang instead by default.

1770
Mark Hammond323b5da2011-10-17 11:05:36 +11001771- Issue #7833: Extension modules built using distutils on Windows will no
1772 longer include a "manifest" to prevent them failing at import time in some
1773 embedded situations.
1774
Benjamin Petersona7b09762011-10-15 13:43:21 -04001775- Issue #13186: Fix __delitem__ on old-style instances when invoked through

1782 name than a Python module (e.g. "__init__.py"): don't close the file twice.
1783
Mark Dickinsondbbed042011-09-19 16:38:08 +01001784- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1785 int.__pow__. These overflow checks were causing int.__pow__ to produce
1786 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001787 compiler optimizing the check away. Also fix similar overflow checks
1788 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1789 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02001800- Issue #12149: Update the method cache after a type's dictionnary gets
1801 cleared by the garbage collector. This fixes a segfault when an instance
1802 and its type get caught in a reference cycle, and the instance's
1803 deallocator calls one of the methods on the type (e.g. when subclassing
1804 IOBase). Diagnosis and patch by Davide Rizzo.
1805
Florent Xiclunaa1f948b2012-01-24 21:05:10 +01001806- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02001813 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
1814 raw_input() interrupted by CTRL+c.
1815
Łukasz Langa7a153902011-10-18 17:16:00 +02001816- Issue #10860: httplib now correctly handles an empty port after port

Florent Xiclunac2279652012-02-12 14:49:03 +01001857- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001858 has left two versions of customize_compiler, the original in
1859 distutils.sysconfig and another copy in distutils.ccompiler, with some
1860 parts of distutils calling one and others using the other.
1861 Complete the revert back to only having one in distutils.sysconfig as
1862 is the case in 3.x.
1863
Ned Deily0d0ea482012-02-10 12:59:06 +01001864- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1865 Distutils-based packages with C extension modules may fail because
1866 Apple has removed gcc-4.2, the version used to build python.org
1867 64-bit/32-bit Pythons. If the user does not explicitly override
1868 the default C compiler by setting the CC environment variable,
1869 Distutils will now attempt to compile extension modules with clang
1870 if gcc-4.2 is required but not found. Also as a convenience, if
1871 the user does explicitly set CC, substitute its value as the default
1872 compiler in the Distutils LDSHARED configuration variable for OS X.
1873 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1874 SDK, neither of which are available in Xcode 4. This change does not
1875 attempt to override settings to support their use with Xcode 4.)
1876

Ned Deily87e82bb2011-06-28 19:52:59 -07002125- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2126 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2127 interpreter process. This could cause failures in non-Distutils subprocesses
2128 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002129 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002130 deployment target only in the environment of each build subprocess. It is
2131 still possible to globally override the default by setting
2132 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2133 greater or equal to the default value, the value with which the interpreter
2134 was built.

2144

2146 connection if its getresponse() method fails with a socket error. Patch
2147 written by Ezio Melotti.
2148

2161
Barry Warsawc5643282011-07-19 17:06:30 -04002162- sys.setcheckinterval() now updates the current ticker count as well as
2163 updating the check interval, so if the user decreases the check interval,
2164 the ticker doesn't have to wind down to zero from the old starting point
2165 before the new interval takes effect. And if the user increases the
2166 interval, it makes sure the new limit takes effect right away rather have an
2167 early task switch before recognizing the new interval.

3148 This prevents user-created self-referencing ordered dictionaries from
3149 becoming permanently uncollectable GC garbage. The downside is that
3150 removing __del__ means that the internal doubly-linked list has to wait for
3151 GC collection rather than freeing memory immediately when the refcnt drops
3152 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003610- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3611 start byte and the continuation byte(s) are now considered invalid, instead
3612 of the number of bytes specified by the start byte.
3613 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3614 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3615 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3616 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003624- Issue #8748: Fix two issues with comparisons between complex and integer
3625 objects. (1) The comparison could incorrectly return True in some cases
3626 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3627 (2) The comparison raised an OverflowError for large integers, leading
3628 to unpredictable exceptions when combining integers and complex objects
3629 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003631- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004011- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4012 with a non-empty format string. This is an effort to future-proof user
4013 code. If a derived class does not currently implement __format__ but later
4014 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004015 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004016 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00004502 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004503 Also, raise ValueError rather than TypeError when an unknown TIPC address

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004508- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004509 file position when calling `truncate()`. It would previously change the file
4510 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004511 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4512

4514 class used to represent files stored inside an archive. The new
4515 implementation is significantly faster and can be wrapped in a
4516 ``io.BufferedReader`` object for more speedups. It also solves an issue
4517 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004528- Issue #7748: Since unicode values are supported for some metadata options in
4529 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4530 encoded string for them. This ensures that the upload and register commands
4531 send the correct values to PyPI without any error.

4606-----------------
4607
Georg Brandlba83f822010-03-14 09:50:54 +00004608- The ``__complex__()`` method is now looked up on the class of instances to
4609 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004611- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4612 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4613
Mark Dickinson1b34d252010-01-01 17:27:30 +00004614- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004615 DeprecationWarning when passed a float argument where an integer was expected.
4616 These functions and methods now raise TypeError instead. The majority of the
4617 effects of this change are in the extension modules, but some core functions
4618 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4619 and many unicode/str methods.

4633 of integers: the result of a/b is now correctly rounded for ints a and b (at
4634 least on IEEE 754 platforms), and in particular does not depend on the
4635 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00004642 executables on OSX.
4643
Georg Brandlba83f822010-03-14 09:50:54 +00004644 These executables now work properly with the arch(1) command: ``arch -ppc
4645 python`` will start a universal binary version of python in PPC mode (unlike
4646 previous releases).

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004800
Georg Brandlba83f822010-03-14 09:50:54 +00004801- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4802 decimal string that's guaranteed to round back to x under correct rounding
4803 (with round-half-to-even rounding mode). Previously it gave a string based on
4804 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4805 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4806 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004807
Georg Brandlba83f822010-03-14 09:50:54 +00004808- Issue #7117: On almost all platforms: float-to-string and string-to-float
4809 conversions within Python are now correctly rounded. Places these conversions
4810 occur include: str for floats and complex numbers; the float and complex
4811 constructors; old-style and new-style numeric formatting; serialization and
4812 deserialization of floats and complex numbers using marshal, pickle and json;
4813 parsing of float and imaginary literals in Python code; Decimal-to-float
4814 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004815
Georg Brandlba83f822010-03-14 09:50:54 +00004816 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4817 providing correctly-rounded strtod and dtoa C functions. This code is
4818 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4819 the C compiler. There may be a small number of platforms on which correct
4820 operation of this code cannot be guaranteed, so the code is not used: notably,
4821 this applies to platforms where the C double format is not IEEE 754 binary64,
4822 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4823 and Python's configure script is unable to determine how to change the FPU
4824 precision. On these platforms conversions use the platform strtod and dtoa,
4825 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004827- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4828 uses the correctly-rounded string <-> float conversions described above (when
4829 available), and so produces correctly rounded results that will display nicely
4830 under the float repr. There are two related small changes: (1) round now
4831 accepts any class with an ``__index__()`` method for its second argument (but
4832 no longer accepts floats for the second argument), and (2) an excessively
4833 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4834 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004981- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4982 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4983 but with at least one decimal point and with a default precision
4984 of 12. Previously, the behavior the same but with a default precision of 6.
4985 This more closely matches ``str()``, and reduces surprises when adding
4986 alignment flags to the empty presentation type. This also affects the new
4987 complex.__format__ in the same way.
4988

Georg Brandlba83f822010-03-14 09:50:54 +00005185- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5186 file objects with closefd=False. The file descriptor is still kept open but
5187 the file object behaves like a closed file. The ``FileIO`` object also got a
5188 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00005211- On windows, ``os.chdir()`` given unicode was not working if

5213 this code path is really executed because I cannot move to such directory on
5214 win2k)

5218 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005239- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5240 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5241 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5242 of using the replace error handler in PyUnicode_DecodeUTF8().
5243
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005244- Issue #3739: The unicode-internal encoder now reports the number of characters

5246
Georg Brandlba83f822010-03-14 09:50:54 +00005247- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5248 allocator will be automatically disabled when running under Valgrind. This
5249 gives improved memory leak detection when running under Valgrind, while taking
5250 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006618- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6619
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006620- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6621 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6622 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6623 ``printf`` function, whereas PyString_FromFormat has an independent
6624 implementation and uses "%zd" on all platforms for size_t values.
6625 This makes a difference on win64, where ``printf`` needs "%Id" to display
6626 64bit values.
6627
Benjamin Peterson97179b02008-09-09 20:55:01 +00006628- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6632 object; previously an int would be returned for small values. the __long__
6633 method is allowed to return either an int or a long, but the behaviour of
6634 float objects should not change to respect backward compatibility.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006642 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006643 was correctly parsed but parsing of subsequent arguments failed.
6644
Vinay Sajip35e3b032008-09-01 14:33:59 +00006645- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006646 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6647 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6648 when given a tuple of classes as second argument, were looking up
6649 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6650 type object.
6651

6795-----------------
6796
Guido van Rossumf8402962008-08-20 15:01:50 +00006797- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6798 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6799 extensions do not automatically benefit from the class attribute
6800 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6801 to their tp_flags field if they care. This is a backwards
6802 compatibility feature; in 3.0, all types will use the cache by
6803 default.
6804
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006805- Keyword arguments can now follow starred arguments. (``f(a, *args,
6806 keyword=23)`` is now valid syntax.)
6807
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006808- ctypes function pointers that are COM methods have a boolean True
6809 value again.
6810
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006811- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6812 by denying s# to parse objects that have a releasebuffer procedure,
6813 and introducing s*.
6814
Georg Brandl1e13ea92008-08-11 09:07:59 +00006815- Issue #3537: Fix an assertion failure when an empty but presized dict
6816 object was stored in the freelist.
6817
Mark Dickinsonb6467572008-08-04 21:30:09 +00006818- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6819 ValueError consistently across platforms.
6820
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006821- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6822 (64bit Unix, for example), unichr() would truncate its argument and return
6823 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6824
Neal Norwitze7d8be82008-07-31 17:17:14 +00006825- Apply security patches from Apple.
6826
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006827- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

6829
Antoine Pitrou92f82162008-07-25 22:22:08 +00006830- Issue #1819: function calls with several named parameters are now on
6831 average 35% faster (as measured by pybench).
6832
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006833- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6834 the python debugger steps into a class statement: the free variables (local
6835 variables defined in an outer scope) would be deleted from the outer scope.
6836
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006837- Issue #2620: Overflow checking when allocating or reallocating memory
6838 was not always being done properly in some python types and extension
6839 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6840 all been updated to perform better checks and places in the code that
6841 would previously leak memory on the error path when such an allocation

6848
Benjamin Petersone977ad42008-08-20 01:42:01 +00006849- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6850 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6851
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006852- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6853 version reported by these tools does not necessarily follow the python
6854 version numbering scheme, so the module is less strict when parsing it.
6855
Nick Coghlanf70385a2008-08-18 12:42:46 +00006856- Issue #2235: Added Py3k warnings for types which will become unhashable
6857 under the stricter __hash__ inheritance rules in 3.0. Several types
6858 which did not meet the rules for hash invariants and were already
6859 unhashable in 3.0 have now been explicitly flagged as unhashable in
6860 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6861 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6862
Brett Cannon88f801d2008-08-18 00:46:22 +00006863- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6864 imported into the module but exposed as part of the module's API.
6865
Brett Cannon7b96f072008-08-18 00:41:11 +00006866- Remove an unneeded import of abc.ABCMeta from 'inspect'.

6871
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006872- Issue #3575: Incremental decoder's decode function now takes bytearray
6873 by using 's*' instead of 't#'.
6874
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006875- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006876 fails unicode conversion on 2nd parameter. (windows only)
6877
Georg Brandl222e2082010-08-01 22:27:39 +00006878- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006879 in a redirect.
6880
Brett Cannonabe423e2008-08-16 21:47:07 +00006881- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006882 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006883
Facundo Batistaeb90b782008-08-16 14:44:07 +00006884- Issue #2776: fixed small issue when handling an URL with double slash
6885 after a 302 response in the case of not going through a proxy.
6886
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006887- Issue #2676: in the email package, content-type parsing was hanging on
6888 pathological input because of quadratic or exponential behaviour of a
6889 regular expression.
6890
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006891- Issue #3476: binary buffered reading through the new "io" library is now
6892 thread-safe.
6893
Brett Cannonbf3157b2008-08-14 05:00:03 +00006894- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6895 since mimetools itself is deprecated. Because modules are cached, all
6896 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6897
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006898- Issue #3134: shutil referenced undefined WindowsError symbol.
6899
Robert Schuppenies14646332008-08-10 11:01:53 +00006900- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6901 menu entries were not deleted.
6902
Brett Cannon83e81842008-08-09 23:30:55 +00006903- Copied the implementation of reduce() to _functools.reduce() to have a
6904 version that did not raise a DeprecationWarning under -3.
6905
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006906- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6907 a MemoryError rather than silently stop the iteration.
6908
Guido van Rossum59ce9012008-08-09 14:55:34 +00006909- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6910 to _sre.compile() will now be rejected. This should not affect anybody
6911 since the re.compile() function never generates invalid re-bytecode.
6912
Skip Montanaroa032bf42008-08-08 22:52:51 +00006913- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6914 upon first access it can be automatically initialized from the csv file if
6915 it wasn't initialized during instantiation.
6916
Brett Cannon3aa2a492008-08-06 22:28:09 +00006917- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6918 the reload() built-in has been removed.
6919
Brett Cannon7e30b672008-08-04 21:52:25 +00006920- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006921 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6929 raised an AttributeError.
6930
Benjamin Peterson01a24322008-07-28 23:35:27 +00006931- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006932 asking for a specific length. This problem only affected files opened
6933 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006934
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006935- Issue #3449: Update decimal module to use most recent specification
6936 (v. 1.68) and tests (v. 2.58) from IBM.
6937

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006958- Issue #3394: zipfile.writestr sets external attributes when passed a
6959 file name rather than a ZipInfo instance, so files are extracted with
6960 mode 0600 rather than 000 under Unix.
6961
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006962- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6963 argument in python 2.5, this broke code that subclassed Popen to include its
6964 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6975 interaction with the tp_hash slot (added in 2.6b2) are now documented
6976
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006977- Issue #643841: The language reference now provides more detailed
6978 coverage of the lookup process for special methods. The disclaimers
6979 regarding lack of coverage of new-style classes have also been
6980 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006988Core and Builtins
6989-----------------
6990
Georg Brandl3e483f62008-07-16 22:57:41 +00006991- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6992 its methods now allow for items objects that can be converted to
6993 an integer using operator.index().
6994
Mark Dickinson64b7e502008-07-16 09:40:03 +00006995- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6996 produced a ValueError instead of giving the correct float.
6997
Eric Smitha5fa5a22008-07-16 00:11:49 +00006998- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6999 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7000
Mark Dickinson7103aa42008-07-15 19:08:33 +00007001- Issue #3008: the float type has a new instance method 'float.hex'
7002 and a new class method 'float.fromhex' to convert floating-point
7003 numbers to and from hexadecimal strings, respectively.
7004
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007005- Issue #2235: __hash__ is once again inherited by default. To allow
7006 collections.Hashable to remain meaningful in the presence of the
7007 default hash implementation (object.__hash__), it is now possible
7008 to explicit block inheritance of hash by setting __hash__=None at
7009 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7010 level.
7011
Nick Coghlanb028f502008-07-13 14:52:36 +00007012- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7013 the parent module cannot be found while performing an absolute import.
7014 This means that an incorrectly defined __package__ attribute will
7015 now only prevent relative imports in that module rather than causing
7016 all imports from that module to fail.
7017
Nick Coghlan14ff9942008-07-08 14:21:42 +00007018- Issue #2517: Allow unicode messages in Exceptions again by correctly
7019 bypassing the instance dictionary when looking up __unicode__ on
7020 new-style classes.
7021
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007022- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7023 set to a custom object whose write() method happens to install
7024 another file in sys.stdout.
7025
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007026- Issue #3088: Corrected a race condition in classes derived from
7027 threading.local: the first member set by a thread could be saved in
7028 another thread's dictionary.
7029
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007030- Issue #3004: Minor change to slice.indices(): the start and stop
7031 arguments are now treated identically, making the behaviour easier
7032 to describe and understand. For example, slice(None, -10,
7033 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7034 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7035 10, -1).
7036
Georg Brandl278fc502008-07-19 12:46:12 +00007037- Issue #3219: Calling a function with repeated keyword arguments,
7038 f(a=2, a=23), would not cause a syntax error. This was a regression
7039 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007040
Georg Brandl278fc502008-07-19 12:46:12 +00007041- Issue #2862: Make int and float freelist management consistent with
7042 other freelists. Changes their CompactFreeList apis into
7043 ClearFreeList apis and calls them via gc.collect().

7047
Thomas Heller57adf222008-08-14 19:10:48 +00007048- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7049 api functions without holding the GIL, which could lead to a fatal
7050 error when they failed.
7051
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007052- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00007060- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7061 ForkingPickler.register() to resolve conflict with ctypes.
7062
Vinay Sajip51e65192008-07-18 09:01:10 +00007063- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00007065- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7066 a valid dlerror() message.
7067
Thomas Heller2bad6572008-07-15 17:19:50 +00007068- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7069 incomplete structure was created.

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007075- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007076
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007077- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7078 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007079 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007080 content-length. The problem had been corrected in the 2.4 branch, but never
7081 merged into trunk.
7082
Georg Brandle78fbcc2008-07-05 10:13:36 +00007083- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007096- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7098
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007099- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00007485- On MacOS X it is now possible to install the framework in 64-bit
7486 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007487 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007488
7489 This is controlled by the configure argument ``--with-universal-archs``:
7490
7491 - ``--with-universal-archs=all``: install 4-way universal
7492
7493 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7494
7495 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7496
7497 This option should be used in combination with ``--enable-universalsdk=``.
7498
7499 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007548- Issue #1631171: Re-implement the 'warnings' module in C (the
7549 original Python code has been kept as backup). This will allow for
7550 using the 'warning's machinery in such places as the parser where
7551 use of pure Python code is not possible. Both the ``showarning()``
7552 and ``formatwarning()`` gain an optional 'line' argument which is
7553 not called by default for backwards-compatibility reasons. Setting
7554 ``warnings.showwarning()`` to an implementation that lacks support
7555 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007618- Issue #2550: The approach used by client/server code for obtaining
7619 ports to listen on in network-oriented tests has been refined in an
7620 effort to facilitate running multiple instances of the entire
7621 regression test suite in parallel without issue.
7622 test_support.bind_port() has been fixed such that it will always
7623 return a unique port -- which wasn't always the case with the
7624 previous implementation, especially if socket options had been set
7625 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7626 new implementation of bind_port() will actually raise an exception
7627 if it is passed an AF_INET/SOCK_STREAM socket with either the
7628 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7629 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7630 the socket it's been passed. This currently only applies to
7631 Windows. This option prevents any other sockets from binding to the
7632 host/port we've bound to, thus removing the possibility of the
7633 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7634 when a second SOCK_STREAM socket binds and accepts to a host/port
7635 that's already been bound by another socket. The optional preferred
7636 port parameter to bind_port() has been removed. Under no
7637 circumstances should tests be hard coding ports!
7638
7639 test_support.find_unused_port() has also been introduced, which will
7640 pass a temporary socket object to bind_port() in order to obtain an
7641 unused port. The temporary socket object is then closed and
7642 deleted, and the port is returned. This method should only be used
7643 for obtaining an unused port in order to pass to an external program
7644 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7645 a parameter to a server-oriented class that doesn't give you direct
7646 access to the underlying socket used.
7647
7648 Finally, test_support.HOST has been introduced, which should be used
7649 for the host argument of any relevant socket calls (i.e. bind and
7650 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007651
7652 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007653 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007654 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7655 test_asynchat and test_socket_ssl.
7656
Georg Brandl3ee81df2008-05-17 18:14:43 +00007657 It is now possible for multiple instances of the regression test
7658 suite to run in parallel without issue.

Christian Heimes5224d282008-02-23 15:01:05 +00007933
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007934- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007935 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007936
Eric Smitha73fbe72008-02-23 03:09:44 +00007937- Added the future_builtins module, which contains hex() and oct().
7938 These are the PEP 3127 version of these functions, designed to be
7939 compatible with the hex() and oct() builtins from Python 3.0. They
7940 differ slightly in their output formats from the existing, unchanged
7941 Python 2.6 builtins. The expected usage of the future_builtins
7942 module is:
7943 from future_builtins import hex, oct
7944
Eric Smith7ef40bf2008-02-20 23:34:22 +00007945- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7946 exponents for exponents with absolute value < 100. Follows C99
7947 standard. This is a change on Windows, which would use 3 digits.
7948 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7949 so that any alterations it does to the resulting string will be
7950 available in stringlib/formatter.h (for float.__format__).
7951
Eric Smith5a3c1352008-02-19 13:21:56 +00007952- Implemented PEP 3101, Advanced String Formatting. This adds a new
7953 builtin format(); a format() method for str and unicode; a
7954 __format__() method to object, str, unicode, int, long, float, and
7955 datetime; the class string.Formatter; and the C API
7956 PyObject_Format().
7957
Georg Brandl3ee81df2008-05-17 18:14:43 +00007958- Fixed several potential crashes, all caused by specially crafted
7959 __del__ methods exploiting objects in temporarily inconsistent
7960 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007961
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007962- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007963 prevent a possible crash: an Abstract Base Class would try to access
7964 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007965
Georg Brandl3ee81df2008-05-17 18:14:43 +00007966- Fixed repr() and str() of complex numbers with infinity or nan as
7967 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007968
Georg Brandl3ee81df2008-05-17 18:14:43 +00007969- Clear all free lists during a gc.collect() of the highest generation
7970 in order to allow pymalloc to free more arenas. Python may give back
7971 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007972
Georg Brandl3ee81df2008-05-17 18:14:43 +00007973- Issue #2045: Fix an infinite recursion triggered when printing a
7974 subclass of collections.defaultdict, if its default_factory is set
7975 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007976
Christian Heimesf75dbef2008-02-08 00:11:31 +00007977- Fixed a minor memory leak in dictobject.c. The content of the free
7978 list was not freed on interpreter shutdown.
7979
Georg Brandl21e99f42010-03-07 15:23:59 +00007980- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007981 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007982
Georg Brandl3ee81df2008-05-17 18:14:43 +00007983- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7984 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007985 to compact the internal free lists of pre-allocted ints and floats.
7986
Georg Brandl3ee81df2008-05-17 18:14:43 +00007987- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7988 calls. Python expected the return type int but the fork familie
7989 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007990
Georg Brandl3ee81df2008-05-17 18:14:43 +00007991- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7992 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007993
Georg Brandl3ee81df2008-05-17 18:14:43 +00007994- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7995 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007996
Georg Brandl3ee81df2008-05-17 18:14:43 +00007997- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7998 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007999
Georg Brandl3ee81df2008-05-17 18:14:43 +00008000- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8001 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008002
Georg Brandl3ee81df2008-05-17 18:14:43 +00008003- Patch #1473257: generator objects gain a gi_code attribute. This is
8004 the same object as the func_code attribute of the function that
8005 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008006
Georg Brandl3ee81df2008-05-17 18:14:43 +00008007- Issue #1920: "while 0" statements were completely removed by the
8008 compiler, even in the presence of an "else" clause, which is
8009 supposed to be run when the condition is false. Now the compiler
8010 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008011
Guido van Rossumeead05f2008-01-24 18:21:02 +00008012- A few crashers fixed: weakref_in_del.py (issue #1377858);
8013 loosing_dict_ref.py (issue #1303614, test67.py);
8014 borrowed_ref_[34].py (not in tracker).
8015
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008016- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008017 suppressed while an extension is loaded by calling SetErrorMode in
8018 dynload_win.c. The error is still reported properly.
8019
Georg Brandl3ee81df2008-05-17 18:14:43 +00008020- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008021 several extension methods and modules do not work without unicode
8022 support.
8023
Georg Brandl26543b12008-01-21 18:36:51 +00008024- Issue #1882: when compiling code from a string, encoding cookies in the
8025 second line of code were not always recognized correctly.
8026
Georg Brandl14404b62008-01-19 19:27:05 +00008027- Issue #1679: "0x" was taken as a valid integer literal.
8028
Georg Brandl6caad7d2008-01-26 14:19:22 +00008029- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008030 added.
8031
Christian Heimesc94e2b52008-01-14 04:13:37 +00008032- sys.float_info / PyFloat_GetInfo: The floating point information
8033 object was converted from a dict to a specialized structseq object.
8034
Georg Brandl3ee81df2008-05-17 18:14:43 +00008035- Patch #1816: Added sys.flags structseq. It exposes the status of
8036 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008037
Georg Brandl3ee81df2008-05-17 18:14:43 +00008038- Objects/structseq.c: Implemented new structseq representation. The
8039 patch makes structseqs (e.g. the return value of os.stat) more
8040 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008041
Georg Brandl3ee81df2008-05-17 18:14:43 +00008042- Patch #1700288: added a type attribute cache that caches method
8043 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008044
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008045- Bug #1776: __import__() no longer accepts filenames on any platform.
8046 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008047
Georg Brandlaed6c662008-01-07 17:25:53 +00008048- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8049
Georg Brandl3ee81df2008-05-17 18:14:43 +00008050- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8051 envvar and sys.dont_write_bytecode attribute. All these can be set
8052 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008053
Georg Brandl3ee81df2008-05-17 18:14:43 +00008054- Improve some exception messages when Windows fails to load an
8055 extension module. Now we get for example '%1 is not a valid Win32
8056 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008057
Georg Brandl3ee81df2008-05-17 18:14:43 +00008058- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008060- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8061 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008062
Christian Heimes0a8143f2007-12-18 23:22:54 +00008063- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064 and INF. float("nan"), float("inf") and float("-inf") now work on
8065 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008066
Georg Brandl3ee81df2008-05-17 18:14:43 +00008067- Compiler now generates simpler and faster code for dictionary
8068 literals. The oparg for BUILD_MAP now indicates an estimated
8069 dictionary size. There is a new opcode, STORE_MAP, for adding
8070 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008071
Georg Brandl3ee81df2008-05-17 18:14:43 +00008072- Issue #1638: %zd configure test fails on Linux.

8085 __package__ attribute.
8086
Georg Brandl3ee81df2008-05-17 18:14:43 +00008087- Issue #1402: Fix a crash on exit, when another thread is still
8088 running, and if the deallocation of its frames somehow calls the
8089 PyGILState_Ensure() / PyGILState_Release() functions.

8100 file can now be directly executed by passing their name to the
8101 interpreter. The directory/zipfile is automatically inserted as the
8102 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008103
Georg Brandl3ee81df2008-05-17 18:14:43 +00008104- Issue #1265: Fix a problem with sys.settrace, if the tracing
8105 function uses a generator expression when at the same time the
8106 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008107
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008108- sets and frozensets now have an isdisjoint() method.
8109
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008110- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00008112- Fix warnings found by the new version of the Coverity checker.
8113
Georg Brandl21e99f42010-03-07 15:23:59 +00008114- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008115 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8116 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008117
Georg Brandl3ee81df2008-05-17 18:14:43 +00008118- Issue #1686386: Tuple's tp_repr did not take into account the
8119 possibility of having a self-referential tuple, which is possible
8120 from C code. Nor did object's tp_str consider that a type's tp_str
8121 could do something that could lead to an inifinite recursion.
8122 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8123 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008124
Georg Brandl3ee81df2008-05-17 18:14:43 +00008125- Issue #1164: It was possible to trigger deadlock when using the
8126 'print' statement to write to a file since the GIL was not released
8127 as needed. Now PyObject_Print() does the right thing along with
8128 various tp_print implementations of the built-in types and those in
8129 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008130
Georg Brandl3ee81df2008-05-17 18:14:43 +00008131- Issue #1147: Exceptions were directly allowing string exceptions in
8132 their throw() method even though string exceptions no longer
8133 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008134

Brett Cannon1e534b52007-09-07 04:18:30 +00008138- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008139 PyObject_Call() never calling back out to Python code to trigger
8140 recursion depth updates/checks. Required the creation of a static
8141 RuntimeError instance in case normalizing an exception put the
8142 recursion check value past its limit. Fixes crashers
8143 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008144

Neal Norwitz0ac60192007-05-27 04:08:54 +00008158- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008159 __*__ attributes. (Some already existed, e.g., __doc__ and
8160 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008161
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008162- Add -3 option to the interpreter to warn about features that are
8163 deprecated and will be changed/removed in Python 3.0.
8164
Georg Brandl2134e752007-05-21 20:34:16 +00008165- Patch #1686487: you can now pass any mapping after '**' in function
8166 calls.
8167
Collin Winter62903052007-05-18 23:11:24 +00008168- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008169 "except E as target:". This is to provide forwards compatibility
8170 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008177- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008178 setting a plain string, ie don't expand to single letter identifiers.

Raymond Hettinger13936692007-04-11 18:40:58 +00008180- Request #1191699: Slices can now be pickled.
8181
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008182- Request #1193128: str.translate() now allows a None argument for
8183 translations that only remove characters without re-mapping the
8184 remaining characters.
8185
Georg Brandl5cb76c12007-03-21 09:00:39 +00008186- Patch #1682205: a TypeError while unpacking an iterable is no longer

Guido van Rossum143b5642007-03-23 04:58:42 +00008191- Bug #1683368: The object.__init__() and object.__new__() methods are
8192 now stricter in rejecting excess arguments. The only time when
8193 either allows excess arguments is when it is not overridden and the
8194 other one is. For backwards compatibility, when both are
8195 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008196 warning later). Also, type.__init__() insists on the same signature
8197 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008199- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8200 object to complex using its __complex__() method before falling back
8201 to the __float__() method. Therefore, the functions in the cmath
8202 module now can operate on objects that define a __complex__()
8203 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008221- Bug #1678647: write a newline after printing an exception in any
8222 case, even when converting the value to a string failed.
8223
Georg Brandl871f1bc2007-03-12 13:17:36 +00008224- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008225 its argument, if it exists. If not, it will work like before. This
8226 allows customizing the output of dir() in the presence of a
8227 __getattr__().

8236 parthensized forms. This means complex(repr(x)) now works instead of
8237 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008238
Georg Brandlaa2321b2007-03-07 00:40:28 +00008239- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008240 makes the filenames the warning module prints much more sensible
8241 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008254- Patch #1674228: when assigning a slice (old-style), check for the
8255 sq_ass_slice instead of the sq_slice slot.
8256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008257- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00008309- Bug #1545497: when given an explicit base, int() did ignore NULs
8310 embedded in the string to convert.
8311
Georg Brandl846f73a2006-10-08 07:11:54 +00008312- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008342- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008360 generator expressions (x for x, in ... ) works again. Fixing this
8361 problem required changing the .pyc magic number. This means that

Georg Brandl3ee81df2008-05-17 18:14:43 +00008791 AttributeError instead of an IOError when the server's response
8792 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008826 are set for invalid interpolation sequences that would lead to
8827 errors on reading back those values.

8883 TestCase and TestSuite subclasses (not instances) are no longer
8884 accepted in TestSuite.addTest(). This should cause no
8885 incompatibility since it never made sense with ordinary subclasses
8886 -- the failure just occurred later, with a more cumbersome
8887 exception.

9160 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009161
Georg Brandl3ee81df2008-05-17 18:14:43 +00009162- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9163 with RFC 3207 and forgets any knowledge obtained from the server not
9164 obtained from the TLS negotiation itself. Patch contributed by Bill
9165 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009166
Georg Brandl3ee81df2008-05-17 18:14:43 +00009167- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009168 that the SMTP.starttls() caller no longer needs to call ehlo()
9169 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009170 does not claim to support starttls. Adds the
9171 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9172 Fenner.

9241 contents before adding elements from the iterable. This fix brings
9242 the behavior into line with that for list.__init__().

9252 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9253 silently miscode subclasses of those types. Now, it raises a
9254 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009255

Georg Brandl3ee81df2008-05-17 18:14:43 +00009270 time so that opening a database previously created with the DB_DUP
9271 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9272 opens. Specifically: dictionary assignment to a DB object will
9273 replace all values for a given key when the database allows
9274 duplicate values. DB users should use DB.put(k, v) when they want
9275 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009276

9282 characters with ASCII value less than 32. Also, it correctly quotes
9283 dots only if they occur on a single line, as opposed to the previous
9284 behavior of quoting dots if they are the second character of any
9285 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009286

Georg Brandl3ee81df2008-05-17 18:14:43 +00009694- Removed the macfs module. It had been deprecated since Python 2.5.
9695 This lead to the deprecation of macostools.touched() as it relied
9696 solely on macfs and was a no-op under OS X.
