Florent Xiclunac2279652012-02-12 14:49:03 +0100893- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100894 has left two versions of customize_compiler, the original in
895 distutils.sysconfig and another copy in distutils.ccompiler, with some
896 parts of distutils calling one and others using the other.
897 Complete the revert back to only having one in distutils.sysconfig as
898 is the case in 3.x.
899
Ned Deily0d0ea482012-02-10 12:59:06 +0100900- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
901 Distutils-based packages with C extension modules may fail because
902 Apple has removed gcc-4.2, the version used to build python.org
903 64-bit/32-bit Pythons. If the user does not explicitly override
904 the default C compiler by setting the CC environment variable,
905 Distutils will now attempt to compile extension modules with clang
906 if gcc-4.2 is required but not found. Also as a convenience, if
907 the user does explicitly set CC, substitute its value as the default
908 compiler in the Distutils LDSHARED configuration variable for OS X.
909 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
910 SDK, neither of which are available in Xcode 4. This change does not
911 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001184- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1185 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1186 interpreter process. This could cause failures in non-Distutils subprocesses
1187 and was unreliable since tests or user programs could modify the interpreter
1188 environment after Distutils set it. Instead, have Distutils set the the
1189 deployment target only in the environment of each build subprocess. It is
1190 still possible to globally override the default by setting
1191 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1192 greater or equal to the default value, the value with which the interpreter
1193 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04001221- sys.setcheckinterval() now updates the current ticker count as well as
1222 updating the check interval, so if the user decreases the check interval,
1223 the ticker doesn't have to wind down to zero from the old starting point
1224 before the new interval takes effect. And if the user increases the
1225 interval, it makes sure the new limit takes effect right away rather have an
1226 early task switch before recognizing the new interval.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002641- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2642 start byte and the continuation byte(s) are now considered invalid, instead
2643 of the number of bytes specified by the start byte.
2644 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2645 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2646 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2647 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002649- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002650 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2651 arises from the "Overriding __eq__ blocks inheritance ..." warning
2652 when turned into an exception: in this case the exception simply
2653 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002654
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002655- Issue #8748: Fix two issues with comparisons between complex and integer
2656 objects. (1) The comparison could incorrectly return True in some cases
2657 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2658 (2) The comparison raised an OverflowError for large integers, leading
2659 to unpredictable exceptions when combining integers and complex objects
2660 in sets or dicts.
2661
Mark Dickinson81336372010-05-30 12:12:25 +00002662- Issue #5211: Implicit coercion for the complex type is now completely
2663 removed. (Coercion for arithmetic operations was already removed in 2.7
2664 alpha 4, but coercion for rich comparisons was accidentally left in.)
2665
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002666- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
2667 and error handler, instead of writing to the C stderr file in utf-8
2668
Georg Brandlfee0f442010-05-22 21:26:21 +00002669- Issue #7902: When using explicit relative import syntax, don't try implicit

3028
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003029- Issue #8329: Don't return the same lists from select.select when no fds are
3030 changed.
3031
Georg Brandlfee0f442010-05-22 21:26:21 +00003032- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003033 on 64-bit machines. The shift count for either left or right shift is
3034 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00003042- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3043 with a non-empty format string. This is an effort to future-proof user
3044 code. If a derived class does not currently implement __format__ but later
3045 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003046 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003047 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003097- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3098 InvalidOperation instead of returning False. (Comparisons involving a quiet
3099 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal

Georg Brandlfee0f442010-05-22 21:26:21 +00003102- Issue #2531: Comparison operations between floats and Decimal instances now
3103 return a result based on the numeric values of the operands; previously they
3104 returned an arbitrary result based on the relative ordering of id(float) and
3105 id(Decimal).

Georg Brandlba83f822010-03-14 09:50:54 +00003418- Issue #7242: On Solaris 9 and earlier calling ``os.fork()`` from within a
Gregory P. Smith9e5d1322010-03-01 01:22:39 +00003419 thread could raise an incorrect RuntimeError about not holding the import
3420 lock. The import lock is now reinitialized after fork.

3433 common TestCase for some tests: test_genericpath.CommonTest.
3434
Georg Brandlba83f822010-03-14 09:50:54 +00003435- Print platform information when running the whole test suite, or using the
3436 ``--verbose`` flag.

Georg Brandlba83f822010-03-14 09:50:54 +00003441- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00003442 is run with the -OO flag. Tests requiring docstrings are skipped.
3443
Georg Brandlba83f822010-03-14 09:50:54 +00003444- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
3445 now also used by regrtest to run all the tests in a temporary directory. The
3446 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
3447 Xicluna who helped with the patch.

3464 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003465 library would return a bogus result; on Solaris, it was possible to crash the
3466 interpreter. Patch by Stefan Krah.

3477 very large step value.
Mark Dickinson36ecd672010-01-29 17:11:39 +00003478
Georg Brandlba83f822010-03-14 09:50:54 +00003479- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
3480 and add the additional members returned in an OSVERSIONINFOEX structure. The
3481 new members are service_pack_major, service_pack_minor, suite_mask, and
3482 product_type.
Eric Smithee931b72010-01-27 00:28:29 +00003483
Georg Brandlba83f822010-03-14 09:50:54 +00003484- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3485 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3486 returning NULL. The macro now returns a statically allocated empty string
3487 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00003488
Antoine Pitrou64672132010-01-13 07:55:48 +00003489- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

Georg Brandlba83f822010-03-14 09:50:54 +00003496 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
3497 strings,
3498 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3499 numeric strings corresponding to subnormal values,
3500 (3) a memory leak for some values large enough to cause overflow, and
3501 (4) a number of flaws that could lead to incorrectly rounded results.
3502

R. David Murray63e4fd72010-02-10 22:42:04 +00003518- Issue #7835: shelve should no longer produce mysterious warnings during
3519 interpreter shutdown.
3520
Georg Brandlba83f822010-03-14 09:50:54 +00003521- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
3522 XML processing instructions and comments. These raw characters are allowed
3523 by the XML specification, and are necessary when outputting e.g. PHP code in
3524 a processing instruction. Patch by Neil Muller.

Vinay Sajip0e6e97d2010-02-04 20:23:45 +00003531
Antoine Pitroud840e512010-02-04 20:20:18 +00003532- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003533 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003534 Also, raise ValueError rather than TypeError when an unknown TIPC address
3535 type is specified. Patch by Brian Curtin.
3536
Vinay Sajip28c382f2010-02-04 18:48:53 +00003537- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003539- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003540 file position when calling `truncate()`. It would previously change the file
3541 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003542 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3543
Georg Brandlba83f822010-03-14 09:50:54 +00003544- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3545 class used to represent files stored inside an archive. The new
3546 implementation is significantly faster and can be wrapped in a
3547 ``io.BufferedReader`` object for more speedups. It also solves an issue
3548 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3549 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00003558
Georg Brandlba83f822010-03-14 09:50:54 +00003559- Issue #7748: Since unicode values are supported for some metadata options in
3560 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3561 encoded string for them. This ensures that the upload and register commands
3562 send the correct values to PyPI without any error.

3638
Georg Brandlba83f822010-03-14 09:50:54 +00003639- The ``__complex__()`` method is now looked up on the class of instances to
3640 make it consistent with other special methods.

3644
Mark Dickinson1b34d252010-01-01 17:27:30 +00003645- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003646 DeprecationWarning when passed a float argument where an integer was expected.
3647 These functions and methods now raise TypeError instead. The majority of the
3648 effects of this change are in the extension modules, but some core functions
3649 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3650 and many unicode/str methods.

3664 of integers: the result of a/b is now correctly rounded for ints a and b (at
3665 least on IEEE 754 platforms), and in particular does not depend on the
3666 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003675 These executables now work properly with the arch(1) command: ``arch -ppc

3824 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003833- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3834 decimal string that's guaranteed to round back to x under correct rounding
3835 (with round-half-to-even rounding mode). Previously it gave a string based on
3836 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3837 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3838 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00003840- Issue #7117: On almost all platforms: float-to-string and string-to-float
3841 conversions within Python are now correctly rounded. Places these conversions
3842 occur include: str for floats and complex numbers; the float and complex
3843 constructors; old-style and new-style numeric formatting; serialization and
3844 deserialization of floats and complex numbers using marshal, pickle and json;
3845 parsing of float and imaginary literals in Python code; Decimal-to-float
3846 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003847
Georg Brandlba83f822010-03-14 09:50:54 +00003848 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3849 providing correctly-rounded strtod and dtoa C functions. This code is
3850 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3851 the C compiler. There may be a small number of platforms on which correct
3852 operation of this code cannot be guaranteed, so the code is not used: notably,
3853 this applies to platforms where the C double format is not IEEE 754 binary64,
3854 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3855 and Python's configure script is unable to determine how to change the FPU
3856 precision. On these platforms conversions use the platform strtod and dtoa,
3857 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003859- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3860 uses the correctly-rounded string <-> float conversions described above (when
3861 available), and so produces correctly rounded results that will display nicely
3862 under the float repr. There are two related small changes: (1) round now
3863 accepts any class with an ``__index__()`` method for its second argument (but
3864 no longer accepts floats for the second argument), and (2) an excessively
3865 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3866 raises an exception.

4093 internal representation of integers, for performance reasons. Base 2**30 is
4094 enabled by default on 64-bit machines. Add --enable-big-digits option to

4245 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00004279- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4280 allocator will be automatically disabled when running under Valgrind. This
4281 gives improved memory leak detection when running under Valgrind, while taking
4282 advantage of pymalloc at other times.

5449 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5450 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005649- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5651 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5652 ``printf`` function, whereas PyString_FromFormat has an independent
5653 implementation and uses "%zd" on all platforms for size_t values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005671 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005672 was correctly parsed but parsing of subsequent arguments failed.
5673
Vinay Sajip35e3b032008-09-01 14:33:59 +00005674- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005675 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5676 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5677 when given a tuple of classes as second argument, were looking up
5678 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5679 type object.
5680
Neal Norwitz18aa3882008-08-24 05:04:52 +00005681- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +00005689- Silenced another compiler warning about a used but not defined
5690 function 'stringlib_contains_obj'.
5691
Benjamin Peterson712ee922008-08-24 18:10:20 +00005692- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

Brett Cannon1eaf0742008-09-02 01:25:16 +00005750 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5751 for catch_warnings() also led to an improvement in the raising of a
5752 DeprecationWarning related to warnings.warn_explicit().
5753

5779 without limit.
5780
Benjamin Peterson37346b22008-08-23 20:27:43 +00005781- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005818What's New in Python 2.6 beta 3?
5819================================
5820
Barry Warsaw07a4a382008-08-21 01:15:08 +00005821*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005822
5823Core and Builtins
5824-----------------
5825
Guido van Rossumf8402962008-08-20 15:01:50 +00005826- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5827 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5828 extensions do not automatically benefit from the class attribute
5829 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5830 to their tp_flags field if they care. This is a backwards
5831 compatibility feature; in 3.0, all types will use the cache by
5832 default.
5833
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005834- Keyword arguments can now follow starred arguments. (``f(a, *args,
5835 keyword=23)`` is now valid syntax.)
5836
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005837- ctypes function pointers that are COM methods have a boolean True
5838 value again.
5839
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005840- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5841 by denying s# to parse objects that have a releasebuffer procedure,
5842 and introducing s*.
5843
Georg Brandl1e13ea92008-08-11 09:07:59 +00005844- Issue #3537: Fix an assertion failure when an empty but presized dict
5845 object was stored in the freelist.
5846
Mark Dickinsonb6467572008-08-04 21:30:09 +00005847- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5848 ValueError consistently across platforms.
5849
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005850- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5851 (64bit Unix, for example), unichr() would truncate its argument and return
5852 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5853
Neal Norwitze7d8be82008-07-31 17:17:14 +00005854- Apply security patches from Apple.
5855
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005856- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5857 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5858
Antoine Pitrou92f82162008-07-25 22:22:08 +00005859- Issue #1819: function calls with several named parameters are now on
5860 average 35% faster (as measured by pybench).
5861
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005862- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5863 the python debugger steps into a class statement: the free variables (local
5864 variables defined in an outer scope) would be deleted from the outer scope.
5865
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005866- Issue #2620: Overflow checking when allocating or reallocating memory
5867 was not always being done properly in some python types and extension
5868 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5869 all been updated to perform better checks and places in the code that
5870 would previously leak memory on the error path when such an allocation
5871 failed have been fixed.

5874-------
5875
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005876- Issue #3612: Added some missing basic types in ctypes.wintypes.
5877
Benjamin Petersone977ad42008-08-20 01:42:01 +00005878- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5879 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5880
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005881- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5882 version reported by these tools does not necessarily follow the python
5883 version numbering scheme, so the module is less strict when parsing it.
5884
Nick Coghlanf70385a2008-08-18 12:42:46 +00005885- Issue #2235: Added Py3k warnings for types which will become unhashable
5886 under the stricter __hash__ inheritance rules in 3.0. Several types
5887 which did not meet the rules for hash invariants and were already
5888 unhashable in 3.0 have now been explicitly flagged as unhashable in
5889 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5890 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5891
Brett Cannon88f801d2008-08-18 00:46:22 +00005892- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5893 imported into the module but exposed as part of the module's API.
5894
Brett Cannon7b96f072008-08-18 00:41:11 +00005895- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5896
Brett Cannon46225e72008-08-18 00:36:52 +00005897- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005899- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5900
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005901- Issue #3575: Incremental decoder's decode function now takes bytearray
5902 by using 's*' instead of 't#'.
5903
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005904- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005905 fails unicode conversion on 2nd parameter. (windows only)
5906
Georg Brandl222e2082010-08-01 22:27:39 +00005907- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005908 in a redirect.
5909
Brett Cannonabe423e2008-08-16 21:47:07 +00005910- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005911 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005912
Facundo Batistaeb90b782008-08-16 14:44:07 +00005913- Issue #2776: fixed small issue when handling an URL with double slash
5914 after a 302 response in the case of not going through a proxy.
5915
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005916- Issue #2676: in the email package, content-type parsing was hanging on
5917 pathological input because of quadratic or exponential behaviour of a
5918 regular expression.
5919
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005920- Issue #3476: binary buffered reading through the new "io" library is now
5921 thread-safe.
5922
Brett Cannonbf3157b2008-08-14 05:00:03 +00005923- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5924 since mimetools itself is deprecated. Because modules are cached, all
5925 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5926
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005927- Issue #3134: shutil referenced undefined WindowsError symbol.
5928
Robert Schuppenies14646332008-08-10 11:01:53 +00005929- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5930 menu entries were not deleted.
5931
Brett Cannon83e81842008-08-09 23:30:55 +00005932- Copied the implementation of reduce() to _functools.reduce() to have a
5933 version that did not raise a DeprecationWarning under -3.
5934
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005935- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5936 a MemoryError rather than silently stop the iteration.
5937
Guido van Rossum59ce9012008-08-09 14:55:34 +00005938- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5939 to _sre.compile() will now be rejected. This should not affect anybody
5940 since the re.compile() function never generates invalid re-bytecode.
5941
Skip Montanaroa032bf42008-08-08 22:52:51 +00005942- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5943 upon first access it can be automatically initialized from the csv file if
5944 it wasn't initialized during instantiation.
5945
Brett Cannon3aa2a492008-08-06 22:28:09 +00005946- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5947 the reload() built-in has been removed.
5948
Brett Cannon7e30b672008-08-04 21:52:25 +00005949- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005950 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005951 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

6005
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006006- Issue #643841: The language reference now provides more detailed
6007 coverage of the lookup process for special methods. The disclaimers
6008 regarding lack of coverage of new-style classes have also been

6013================================
6014
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006015*Release date: 17-Jul-2008*

6018-----------------
6019
Georg Brandl3e483f62008-07-16 22:57:41 +00006020- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6021 its methods now allow for items objects that can be converted to
6022 an integer using operator.index().
6023
Mark Dickinson64b7e502008-07-16 09:40:03 +00006024- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6025 produced a ValueError instead of giving the correct float.
6026
Eric Smitha5fa5a22008-07-16 00:11:49 +00006027- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6028 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6029
Mark Dickinson7103aa42008-07-15 19:08:33 +00006030- Issue #3008: the float type has a new instance method 'float.hex'
6031 and a new class method 'float.fromhex' to convert floating-point
6032 numbers to and from hexadecimal strings, respectively.
6033
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006034- Issue #2235: __hash__ is once again inherited by default. To allow
6035 collections.Hashable to remain meaningful in the presence of the
6036 default hash implementation (object.__hash__), it is now possible
6037 to explicit block inheritance of hash by setting __hash__=None at
6038 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6039 level.
6040
Nick Coghlanb028f502008-07-13 14:52:36 +00006041- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6042 the parent module cannot be found while performing an absolute import.
6043 This means that an incorrectly defined __package__ attribute will
6044 now only prevent relative imports in that module rather than causing
6045 all imports from that module to fail.
6046
Nick Coghlan14ff9942008-07-08 14:21:42 +00006047- Issue #2517: Allow unicode messages in Exceptions again by correctly
6048 bypassing the instance dictionary when looking up __unicode__ on
6049 new-style classes.

6052 set to a custom object whose write() method happens to install
6053 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006055- Issue #3088: Corrected a race condition in classes derived from
6056 threading.local: the first member set by a thread could be saved in
6057 another thread's dictionary.
6058
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006059- Issue #3004: Minor change to slice.indices(): the start and stop
6060 arguments are now treated identically, making the behaviour easier
6061 to describe and understand. For example, slice(None, -10,
6062 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6063 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6064 10, -1).
6065
Georg Brandl278fc502008-07-19 12:46:12 +00006066- Issue #3219: Calling a function with repeated keyword arguments,
6067 f(a=2, a=23), would not cause a syntax error. This was a regression
6068 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006069
Georg Brandl278fc502008-07-19 12:46:12 +00006070- Issue #2862: Make int and float freelist management consistent with
6071 other freelists. Changes their CompactFreeList apis into
6072 ClearFreeList apis and calls them via gc.collect().

6078 api functions without holding the GIL, which could lead to a fatal
6079 error when they failed.
6080
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006081- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006106- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6107 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006108 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006109 content-length. The problem had been corrected in the 2.4 branch, but never
6110 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006125- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6126 handling is now the same as that of other special attributes like __name__).
6127
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006128- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6520 This is controlled by the configure argument ``--with-universal-archs``:
6521
6522 - ``--with-universal-archs=all``: install 4-way universal
6523
6524 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6525
6526 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6527
6528 This option should be used in combination with ``--enable-universalsdk=``.
6529
6530 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 +00006539
6540- The PyString functions have been renamed to PyBytes. A batch of
6541 defines were added so that the linker still sees the original
6542 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006580- Issue #1631171: Re-implement the 'warnings' module in C (the
6581 original Python code has been kept as backup). This will allow for
6582 using the 'warning's machinery in such places as the parser where
6583 use of pure Python code is not possible. Both the ``showarning()``
6584 and ``formatwarning()`` gain an optional 'line' argument which is
6585 not called by default for backwards-compatibility reasons. Setting
6586 ``warnings.showwarning()`` to an implementation that lacks support
6587 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006629- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006630 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006650- Issue #2550: The approach used by client/server code for obtaining
6651 ports to listen on in network-oriented tests has been refined in an
6652 effort to facilitate running multiple instances of the entire
6653 regression test suite in parallel without issue.
6654 test_support.bind_port() has been fixed such that it will always
6655 return a unique port -- which wasn't always the case with the
6656 previous implementation, especially if socket options had been set
6657 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6658 new implementation of bind_port() will actually raise an exception
6659 if it is passed an AF_INET/SOCK_STREAM socket with either the
6660 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6661 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6662 the socket it's been passed. This currently only applies to
6663 Windows. This option prevents any other sockets from binding to the
6664 host/port we've bound to, thus removing the possibility of the
6665 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6666 when a second SOCK_STREAM socket binds and accepts to a host/port
6667 that's already been bound by another socket. The optional preferred
6668 port parameter to bind_port() has been removed. Under no
6669 circumstances should tests be hard coding ports!
6670
6671 test_support.find_unused_port() has also been introduced, which will
6672 pass a temporary socket object to bind_port() in order to obtain an
6673 unused port. The temporary socket object is then closed and
6674 deleted, and the port is returned. This method should only be used
6675 for obtaining an unused port in order to pass to an external program
6676 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6677 a parameter to a server-oriented class that doesn't give you direct
6678 access to the underlying socket used.
6679
6680 Finally, test_support.HOST has been introduced, which should be used
6681 for the host argument of any relevant socket calls (i.e. bind and
6682 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006683
6684 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006685 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006686 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6687 test_asynchat and test_socket_ssl.
6688
Georg Brandl3ee81df2008-05-17 18:14:43 +00006689 It is now possible for multiple instances of the regression test
6690 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006969- Added the future_builtins module, which contains hex() and oct().
6970 These are the PEP 3127 version of these functions, designed to be
6971 compatible with the hex() and oct() builtins from Python 3.0. They
6972 differ slightly in their output formats from the existing, unchanged
6973 Python 2.6 builtins. The expected usage of the future_builtins
6974 module is:
6975 from future_builtins import hex, oct
6976
Eric Smith7ef40bf2008-02-20 23:34:22 +00006977- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6978 exponents for exponents with absolute value < 100. Follows C99
6979 standard. This is a change on Windows, which would use 3 digits.
6980 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6981 so that any alterations it does to the resulting string will be
6982 available in stringlib/formatter.h (for float.__format__).
6983
Eric Smith5a3c1352008-02-19 13:21:56 +00006984- Implemented PEP 3101, Advanced String Formatting. This adds a new
6985 builtin format(); a format() method for str and unicode; a
6986 __format__() method to object, str, unicode, int, long, float, and
6987 datetime; the class string.Formatter; and the C API
6988 PyObject_Format().
6989
Georg Brandl3ee81df2008-05-17 18:14:43 +00006990- Fixed several potential crashes, all caused by specially crafted
6991 __del__ methods exploiting objects in temporarily inconsistent
6992 state.

7003 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007004
Georg Brandl3ee81df2008-05-17 18:14:43 +00007005- Issue #2045: Fix an infinite recursion triggered when printing a
7006 subclass of collections.defaultdict, if its default_factory is set
7007 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007008
Christian Heimesf75dbef2008-02-08 00:11:31 +00007009- Fixed a minor memory leak in dictobject.c. The content of the free

7018
Georg Brandl3ee81df2008-05-17 18:14:43 +00007019- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7020 calls. Python expected the return type int but the fork familie
7021 returns pi_t.

7036 the same object as the func_code attribute of the function that
7037 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007038
Georg Brandl3ee81df2008-05-17 18:14:43 +00007039- Issue #1920: "while 0" statements were completely removed by the
7040 compiler, even in the presence of an "else" clause, which is
7041 supposed to be run when the condition is false. Now the compiler
7042 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007043
Guido van Rossumeead05f2008-01-24 18:21:02 +00007044- A few crashers fixed: weakref_in_del.py (issue #1377858);
7045 loosing_dict_ref.py (issue #1303614, test67.py);
7046 borrowed_ref_[34].py (not in tracker).
7047
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007048- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007049 suppressed while an extension is loaded by calling SetErrorMode in
7050 dynload_win.c. The error is still reported properly.
7051
Georg Brandl3ee81df2008-05-17 18:14:43 +00007052- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007053 several extension methods and modules do not work without unicode
7054 support.
7055
Georg Brandl26543b12008-01-21 18:36:51 +00007056- Issue #1882: when compiling code from a string, encoding cookies in the
7057 second line of code were not always recognized correctly.
7058
Georg Brandl14404b62008-01-19 19:27:05 +00007059- Issue #1679: "0x" was taken as a valid integer literal.
7060
Georg Brandl6caad7d2008-01-26 14:19:22 +00007061- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007062 added.
7063
Christian Heimesc94e2b52008-01-14 04:13:37 +00007064- sys.float_info / PyFloat_GetInfo: The floating point information
7065 object was converted from a dict to a specialized structseq object.
7066
Georg Brandl3ee81df2008-05-17 18:14:43 +00007067- Patch #1816: Added sys.flags structseq. It exposes the status of
7068 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007069
Georg Brandl3ee81df2008-05-17 18:14:43 +00007070- Objects/structseq.c: Implemented new structseq representation. The
7071 patch makes structseqs (e.g. the return value of os.stat) more
7072 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007073
Georg Brandl3ee81df2008-05-17 18:14:43 +00007074- Patch #1700288: added a type attribute cache that caches method
7075 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007076
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007077- Bug #1776: __import__() no longer accepts filenames on any platform.
7078 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007079
Georg Brandlaed6c662008-01-07 17:25:53 +00007080- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7081
Georg Brandl3ee81df2008-05-17 18:14:43 +00007082- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7083 envvar and sys.dont_write_bytecode attribute. All these can be set
7084 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007085
Georg Brandl3ee81df2008-05-17 18:14:43 +00007086- Improve some exception messages when Windows fails to load an
7087 extension module. Now we get for example '%1 is not a valid Win32
7088 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007089
Georg Brandl3ee81df2008-05-17 18:14:43 +00007090- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00007091
Georg Brandl3ee81df2008-05-17 18:14:43 +00007092- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7093 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007094
Christian Heimes0a8143f2007-12-18 23:22:54 +00007095- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007096 and INF. float("nan"), float("inf") and float("-inf") now work on
7097 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007098
Georg Brandl3ee81df2008-05-17 18:14:43 +00007099- Compiler now generates simpler and faster code for dictionary
7100 literals. The oparg for BUILD_MAP now indicates an estimated
7101 dictionary size. There is a new opcode, STORE_MAP, for adding
7102 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007103
Georg Brandl3ee81df2008-05-17 18:14:43 +00007104- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00007105
Georg Brandl3ee81df2008-05-17 18:14:43 +00007106- Issue #1620: New property decorator syntax was modifying the
7107 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00007108
Georg Brandl3ee81df2008-05-17 18:14:43 +00007109- Issue #1538: Avoid copying string in split/rsplit if the split char
7110 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007111
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007112- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007113 SystemError.
7114
Nick Coghlanef01d822007-12-03 12:55:17 +00007115- PEP 366: Allow explicit relative imports when executing modules
7116 inside packages with the -m switch via a new module level
7117 __package__ attribute.
7118
Georg Brandl3ee81df2008-05-17 18:14:43 +00007119- Issue #1402: Fix a crash on exit, when another thread is still
7120 running, and if the deallocation of its frames somehow calls the
7121 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007122

7124
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00007125- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007126 attribute of an empty cell object.
7127
Georg Brandl3ee81df2008-05-17 18:14:43 +00007128- Issue #1460: The utf-7 incremental decoder did not accept truncated
7129 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007130
Georg Brandl3ee81df2008-05-17 18:14:43 +00007131- Patch #1739468: Directories and zipfiles containing a __main__.py
7132 file can now be directly executed by passing their name to the
7133 interpreter. The directory/zipfile is automatically inserted as the
7134 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007135
Georg Brandl3ee81df2008-05-17 18:14:43 +00007136- Issue #1265: Fix a problem with sys.settrace, if the tracing
7137 function uses a generator expression when at the same time the
7138 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007139
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007140- sets and frozensets now have an isdisjoint() method.
7141
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007142- optimize the performance of builtin.sum().
7143
Neal Norwitz44f326e2007-10-05 05:29:17 +00007144- Fix warnings found by the new version of the Coverity checker.
7145
Georg Brandl21e99f42010-03-07 15:23:59 +00007146- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007147 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7148 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007149
Georg Brandl3ee81df2008-05-17 18:14:43 +00007150- Issue #1686386: Tuple's tp_repr did not take into account the
7151 possibility of having a self-referential tuple, which is possible
7152 from C code. Nor did object's tp_str consider that a type's tp_str
7153 could do something that could lead to an inifinite recursion.
7154 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7155 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007156
Georg Brandl3ee81df2008-05-17 18:14:43 +00007157- Issue #1164: It was possible to trigger deadlock when using the
7158 'print' statement to write to a file since the GIL was not released
7159 as needed. Now PyObject_Print() does the right thing along with
7160 various tp_print implementations of the built-in types and those in
7161 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007162
Georg Brandl3ee81df2008-05-17 18:14:43 +00007163- Issue #1147: Exceptions were directly allowing string exceptions in
7164 their throw() method even though string exceptions no longer
7165 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007166
Georg Brandl3ee81df2008-05-17 18:14:43 +00007167- Issue #1096: Prevent a segfault from getting the repr of a very
7168 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007169
Brett Cannon1e534b52007-09-07 04:18:30 +00007170- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007171 PyObject_Call() never calling back out to Python code to trigger
7172 recursion depth updates/checks. Required the creation of a static
7173 RuntimeError instance in case normalizing an exception put the
7174 recursion check value past its limit. Fixes crashers
7175 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007176
Georg Brandl3ee81df2008-05-17 18:14:43 +00007177- Patch #1031213: Decode source line in SyntaxErrors back to its
7178 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00007179
Georg Brandl7c3b50d2007-07-12 08:38:00 +00007180- Patch #1673759: add a missing overflow check when formatting floats
7181 with %G.
7182
Georg Brandl3ee81df2008-05-17 18:14:43 +00007183- Prevent expandtabs() on string and unicode objects from causing a
7184 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007185

Georg Brandla5ea6892007-06-01 11:33:33 +00007189
Neal Norwitz0ac60192007-05-27 04:08:54 +00007190- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007191 __*__ attributes. (Some already existed, e.g., __doc__ and
7192 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007193
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007194- Add -3 option to the interpreter to warn about features that are
7195 deprecated and will be changed/removed in Python 3.0.
7196
Georg Brandl2134e752007-05-21 20:34:16 +00007197- Patch #1686487: you can now pass any mapping after '**' in function
7198 calls.
7199
Collin Winter62903052007-05-18 23:11:24 +00007200- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007201 "except E as target:". This is to provide forwards compatibility
7202 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007203
Brett Cannon229cee22007-05-05 01:34:02 +00007204- Deprecate BaseException.message as per PEP 352.
7205
Georg Brandl3ee81df2008-05-17 18:14:43 +00007206- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007207 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007208
Vinay Sajip8549ce32007-05-06 17:53:37 +00007209- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007210 setting a plain string, ie don't expand to single letter identifiers.
7211
Raymond Hettinger13936692007-04-11 18:40:58 +00007212- Request #1191699: Slices can now be pickled.
7213
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007214- Request #1193128: str.translate() now allows a None argument for
7215 translations that only remove characters without re-mapping the
7216 remaining characters.
7217
Georg Brandl5cb76c12007-03-21 09:00:39 +00007218- Patch #1682205: a TypeError while unpacking an iterable is no longer
7219 masked by a generic one with the message "unpack non-sequence".
7220
Neal Norwitzaa754b72007-03-21 06:39:48 +00007221- Remove unused file Python/fmod.c.
7222
Guido van Rossum143b5642007-03-23 04:58:42 +00007223- Bug #1683368: The object.__init__() and object.__new__() methods are
7224 now stricter in rejecting excess arguments. The only time when
7225 either allows excess arguments is when it is not overridden and the
7226 other one is. For backwards compatibility, when both are
7227 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007228 warning later). Also, type.__init__() insists on the same signature
7229 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007230
Georg Brandl3ee81df2008-05-17 18:14:43 +00007231- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7232 object to complex using its __complex__() method before falling back
7233 to the __float__() method. Therefore, the functions in the cmath
7234 module now can operate on objects that define a __complex__()
7235 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007236
Georg Brandl3ee81df2008-05-17 18:14:43 +00007237- Patch #1623563: allow __class__ assignment for classes with
7238 __slots__. The old and the new class are still required to have the
7239 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007240
Georg Brandl3ee81df2008-05-17 18:14:43 +00007241- Patch #1642547: Fix an error/crash when encountering syntax errors
7242 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007244- Patch #1462488: Python no longer segfaults when
7245 ``object.__reduce_ex__()`` is called with an object that is faking
7246 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007247
Georg Brandl3ee81df2008-05-17 18:14:43 +00007248- Patch #1680015: Don't modify __slots__ tuple if it contains an
7249 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00007251- Patch #1444529: the builtin compile() now accepts keyword arguments.
7252
Georg Brandl7b9c5552007-03-12 14:30:05 +00007253- Bug #1678647: write a newline after printing an exception in any
7254 case, even when converting the value to a string failed.
7255
Georg Brandl871f1bc2007-03-12 13:17:36 +00007256- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007257 its argument, if it exists. If not, it will work like before. This
7258 allows customizing the output of dir() in the presence of a
7259 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007260
Collin Winter276887b2007-03-12 16:11:39 +00007261- Patch #922167: Python no longer segfaults when faced with infinitely
7262 self-recursive reload() calls (as reported by bug #742342).
7263
Georg Brandl3ee81df2008-05-17 18:14:43 +00007264- Patch #1675981: remove unreachable code from ``type.__new__()``
7265 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00007266
Georg Brandl3ee81df2008-05-17 18:14:43 +00007267- Patch #1491866: change the complex() constructor to allow
7268 parthensized forms. This means complex(repr(x)) now works instead of
7269 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007270
Georg Brandlaa2321b2007-03-07 00:40:28 +00007271- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007272 makes the filenames the warning module prints much more sensible

7780 ".cpp" too.
7781
Facundo Batistad918a652007-04-24 13:54:38 +00007782- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007783 the client's request was successfully received, understood, and
7784 accepted. Now in these cases no error is raised in urllib (issue
7785 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00007786

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007793- Added a timeout parameter to the constructor of other protocols
7794 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7795 work started with create_connection() and timeout in httplib, and
7796 closes patch #723312.
7797
Vinay Sajip8549ce32007-05-06 17:53:37 +00007798- Patch #1676823: Added create_connection() to socket.py, which may be
7799 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007800 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007801
Martin v. Löwis0af33882007-03-23 13:27:15 +00007802- Bug #978833: Revert r50844, as it broke _socketobject.dup.

7822
Georg Brandlf66b6032007-03-14 08:27:52 +00007823- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007824 AttributeError instead of an IOError when the server's response
7825 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007826
Georg Brandl3ee81df2008-05-17 18:14:43 +00007827- Patch #957650: "%var%" environment variable references are now
7828 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00007830
Georg Brandl3ee81df2008-05-17 18:14:43 +00007831- Patch #1429539: pdb now correctly initializes the __main__ module
7832 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007833 correctly now.
7834
Georg Brandlbad6f192007-03-13 21:32:56 +00007835- The nonobvious commands.getstatus() function is now deprecated.

7841
Georg Brandl3ee81df2008-05-17 18:14:43 +00007842- Patch #1530482: add pydoc.render_doc() which returns the
7843 documentation for a thing instead of paging it to stdout, which
7844 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007845
Georg Brandl3ee81df2008-05-17 18:14:43 +00007846- Patch #1533909: the timeit module now accepts callables in addition

7852 parameter which can be set to False to prevent the default
7853 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00007855- Patch #1581073: add a flag to textwrap that prevents the dropping of
7856 whitespace while wrapping.
7857
Georg Brandl92a6bae2007-03-13 17:43:32 +00007858- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007859 are set for invalid interpolation sequences that would lead to
7860 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007861

7874
Georg Brandl94fe3f52007-03-13 09:32:11 +00007875- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00007876 field names in its exception message if you try to write a record
7877 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00007895
Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +00007896- Patch #742598: Add .timeout attribute to SocketServer that calls

7903 returned string up to the first NUL character.
7904

7914
Georg Brandl3ee81df2008-05-17 18:14:43 +00007915- unittest now verifies more of its assumptions. In particular,
7916 TestCase and TestSuite subclasses (not instances) are no longer
7917 accepted in TestSuite.addTest(). This should cause no
7918 incompatibility since it never made sense with ordinary subclasses
7919 -- the failure just occurred later, with a more cumbersome
7920 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00007921

7929 given a unicode argument and os.listdir() returns unicode filenames.
7930
Georg Brandl3ee81df2008-05-17 18:14:43 +00007931- Patch #1673619: setup.py identifies extension modules it doesn't

7933 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008309 time so that opening a database previously created with the DB_DUP
8310 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8311 opens. Specifically: dictionary assignment to a DB object will
8312 replace all values for a given key when the database allows
8313 duplicate values. DB users should use DB.put(k, v) when they want
8314 to store duplicates; not DB[k] = v.

8321 characters with ASCII value less than 32. Also, it correctly quotes
8322 dots only if they occur on a single line, as opposed to the previous
8323 behavior of quoting dots if they are the second character of any
8324 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008325
