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

260 GC collection rather than freeing memory immediately when the refcnt drops
261 to zero.

270 original error is re-raised.

280 ConfigParser.write.
281
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000282- Issue #808164: Fixed socket.close to avoid references to globals, to
283 avoid issues when socket.close is called from a __del__ method.
284

293 character years even if the message contains RFC822 two character years.
294
Daniel Stutzbach91287322010-08-24 21:09:30 +0000295- Issue #8750: Fixed MutableSet's methods to correctly handle

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000719- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
720 start byte and the continuation byte(s) are now considered invalid, instead
721 of the number of bytes specified by the start byte.
722 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
723 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
724 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

734 objects. (1) The comparison could incorrectly return True in some cases
735 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
736 (2) The comparison raised an OverflowError for large integers, leading

1177 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1178 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001197- Comparisons using one of <, <=, >, >= between a complex instance and a
1198 Fractions instance now raise TypeError instead of returning True/False. This
1199 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1200 <=> complex, and complex <=> complex comparisons.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001613- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001614 file position when calling `truncate()`. It would previously change the file
1615 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001616 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00001618- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1619 class used to represent files stored inside an archive. The new
1620 implementation is significantly faster and can be wrapped in a
1621 ``io.BufferedReader`` object for more speedups. It also solves an issue
1622 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001713- The ``__complex__()`` method is now looked up on the class of instances to
1714 make it consistent with other special methods.

1718
Mark Dickinson1b34d252010-01-01 17:27:30 +00001719- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001720 DeprecationWarning when passed a float argument where an integer was expected.
1721 These functions and methods now raise TypeError instead. The majority of the
1722 effects of this change are in the extension modules, but some core functions
1723 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1724 and many unicode/str methods.

1738 of integers: the result of a/b is now correctly rounded for ints a and b (at
1739 least on IEEE 754 platforms), and in particular does not depend on the
1740 internal representation of a long.

1891 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001892
Georg Brandlba83f822010-03-14 09:50:54 +00001893- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1894 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00001896- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

1898 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001906
Georg Brandlba83f822010-03-14 09:50:54 +00001907- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1908 decimal string that's guaranteed to round back to x under correct rounding
1909 (with round-half-to-even rounding mode). Previously it gave a string based on
1910 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1911 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1912 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001913
Georg Brandlba83f822010-03-14 09:50:54 +00001914- Issue #7117: On almost all platforms: float-to-string and string-to-float
1915 conversions within Python are now correctly rounded. Places these conversions
1916 occur include: str for floats and complex numbers; the float and complex
1917 constructors; old-style and new-style numeric formatting; serialization and
1918 deserialization of floats and complex numbers using marshal, pickle and json;
1919 parsing of float and imaginary literals in Python code; Decimal-to-float
1920 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001921
Georg Brandlba83f822010-03-14 09:50:54 +00001922 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1923 providing correctly-rounded strtod and dtoa C functions. This code is
1924 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1925 the C compiler. There may be a small number of platforms on which correct
1926 operation of this code cannot be guaranteed, so the code is not used: notably,
1927 this applies to platforms where the C double format is not IEEE 754 binary64,
1928 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1929 and Python's configure script is unable to determine how to change the FPU
1930 precision. On these platforms conversions use the platform strtod and dtoa,
1931 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001932
Georg Brandlba83f822010-03-14 09:50:54 +00001933- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1934 uses the correctly-rounded string <-> float conversions described above (when
1935 available), and so produces correctly rounded results that will display nicely
1936 under the float repr. There are two related small changes: (1) round now
1937 accepts any class with an ``__index__()`` method for its second argument (but
1938 no longer accepts floats for the second argument), and (2) an excessively
1939 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1940 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002082
Georg Brandlba83f822010-03-14 09:50:54 +00002083 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2084 (2) parsing of strings representing infinities and nans was locale aware; and
2085 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002087- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2088 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2089 but with at least one decimal point and with a default precision
2090 of 12. Previously, the behavior the same but with a default precision of 6.
2091 This more closely matches ``str()``, and reduces surprises when adding
2092 alignment flags to the empty presentation type. This also affects the new
2093 complex.__format__ in the same way.
2094
2095- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00003579 leak-chasing test runs give sensible results. The previous method of reaping
3580 threads could return successfully while some Thread objects were still
3581 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandl2bd92a52009-10-11 21:10:07 +00003701- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00003702 AttributeError instead of RuntimeError, depending in which C API call
3703 exactly the recursion limit is exceeded. Consequently, both exception types
3704 are caught and silenced.

3720
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003721- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3722
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003723- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3724 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3725 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3726 ``printf`` function, whereas PyString_FromFormat has an independent
3727 implementation and uses "%zd" on all platforms for size_t values.
3728 This makes a difference on win64, where ``printf`` needs "%Id" to display
3729 64bit values.
3730
Benjamin Peterson97179b02008-09-09 20:55:01 +00003731- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3732 error.
3733
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003734- Issue #3777: long() applied to a float object now always return a long
3735 object; previously an int would be returned for small values. the __long__
3736 method is allowed to return either an int or a long, but the behaviour of
3737 float objects should not change to respect backward compatibility.
3738
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003739- Issue #3751: str.rpartition would perform a left-partition when called with
3740 a unicode argument.
3741
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003742- Issue #3683: Fix compilation when --without-threads is given.
3743
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003744- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003745 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003746 was correctly parsed but parsing of subsequent arguments failed.
3747
Vinay Sajip35e3b032008-09-01 14:33:59 +00003748- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003749 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3750 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3751 when given a tuple of classes as second argument, were looking up
3752 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3753 type object.
3754
Neal Norwitz18aa3882008-08-24 05:04:52 +00003755- Fix crashes on memory allocation failure found with failmalloc.
3756
3757- Fix memory leaks found with valgrind and update suppressions file.
3758
3759- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3760
3761- Fix problem using wrong name in decimal module reported by pychecker.
3762
Christian Heimes7d4c3172008-08-22 19:47:25 +00003763- Silenced another compiler warning about a used but not defined
3764 function 'stringlib_contains_obj'.
3765
Benjamin Peterson712ee922008-08-24 18:10:20 +00003766- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3767 ``__delslice__``.
3768
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003769- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3770 library targets in the Makefile.
3771
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003772- Issue #1204: The configure script now tests for additional libraries
3773 that may be required when linking against readline. This fixes issues
3774 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

3785 stack usage in the case of deeply nested objects.
3786

Nick Coghland2e09382008-09-11 12:11:06 +00003797- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003798 return a list or None rather than a custom object.
3799
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003800- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003824 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3825 for catch_warnings() also led to an improvement in the raising of a
3826 DeprecationWarning related to warnings.warn_explicit().
3827
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003828- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003851- Issue #2975: When compiling several extension modules with Visual Studio 2008
3852 from the same python interpreter, some environment variables would grow
3853 without limit.
3854
Benjamin Peterson37346b22008-08-23 20:27:43 +00003855- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3856 exploitation of poor argument checking.

3898-----------------
3899
Guido van Rossumf8402962008-08-20 15:01:50 +00003900- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3901 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3902 extensions do not automatically benefit from the class attribute
3903 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3904 to their tp_flags field if they care. This is a backwards
3905 compatibility feature; in 3.0, all types will use the cache by
3906 default.
3907
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003908- Keyword arguments can now follow starred arguments. (``f(a, *args,
3909 keyword=23)`` is now valid syntax.)
3910
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003911- ctypes function pointers that are COM methods have a boolean True
3912 value again.
3913
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003914- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3915 by denying s# to parse objects that have a releasebuffer procedure,
3916 and introducing s*.
3917
Georg Brandl1e13ea92008-08-11 09:07:59 +00003918- Issue #3537: Fix an assertion failure when an empty but presized dict
3919 object was stored in the freelist.
3920
Mark Dickinsonb6467572008-08-04 21:30:09 +00003921- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3922 ValueError consistently across platforms.
3923
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003924- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3925 (64bit Unix, for example), unichr() would truncate its argument and return
3926 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3927
Neal Norwitze7d8be82008-07-31 17:17:14 +00003928- Apply security patches from Apple.
3929
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003930- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3931 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3932
Antoine Pitrou92f82162008-07-25 22:22:08 +00003933- Issue #1819: function calls with several named parameters are now on
3934 average 35% faster (as measured by pybench).
3935
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003936- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3937 the python debugger steps into a class statement: the free variables (local
3938 variables defined in an outer scope) would be deleted from the outer scope.
3939
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003940- Issue #2620: Overflow checking when allocating or reallocating memory
3941 was not always being done properly in some python types and extension
3942 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3943 all been updated to perform better checks and places in the code that
3944 would previously leak memory on the error path when such an allocation
3945 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003950- Issue #3612: Added some missing basic types in ctypes.wintypes.
3951
Benjamin Petersone977ad42008-08-20 01:42:01 +00003952- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3953 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3954
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003955- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3956 version reported by these tools does not necessarily follow the python
3957 version numbering scheme, so the module is less strict when parsing it.
3958
Nick Coghlanf70385a2008-08-18 12:42:46 +00003959- Issue #2235: Added Py3k warnings for types which will become unhashable
3960 under the stricter __hash__ inheritance rules in 3.0. Several types
3961 which did not meet the rules for hash invariants and were already
3962 unhashable in 3.0 have now been explicitly flagged as unhashable in
3963 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3964 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3965
Brett Cannon88f801d2008-08-18 00:46:22 +00003966- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3967 imported into the module but exposed as part of the module's API.
3968
Brett Cannon7b96f072008-08-18 00:41:11 +00003969- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3970
Brett Cannon46225e72008-08-18 00:36:52 +00003971- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003973- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3974
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003975- Issue #3575: Incremental decoder's decode function now takes bytearray
3976 by using 's*' instead of 't#'.

4079
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004080- Issue #643841: The language reference now provides more detailed

4093
Georg Brandl3e483f62008-07-16 22:57:41 +00004094- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4095 its methods now allow for items objects that can be converted to
4096 an integer using operator.index().
4097
Mark Dickinson64b7e502008-07-16 09:40:03 +00004098- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4099 produced a ValueError instead of giving the correct float.
4100
Eric Smitha5fa5a22008-07-16 00:11:49 +00004101- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4102 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4103
Mark Dickinson7103aa42008-07-15 19:08:33 +00004104- Issue #3008: the float type has a new instance method 'float.hex'
4105 and a new class method 'float.fromhex' to convert floating-point
4106 numbers to and from hexadecimal strings, respectively.
4107
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004108- Issue #2235: __hash__ is once again inherited by default. To allow
4109 collections.Hashable to remain meaningful in the presence of the
4110 default hash implementation (object.__hash__), it is now possible
4111 to explicit block inheritance of hash by setting __hash__=None at
4112 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4113 level.
4114
Nick Coghlanb028f502008-07-13 14:52:36 +00004115- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4116 the parent module cannot be found while performing an absolute import.
4117 This means that an incorrectly defined __package__ attribute will
4118 now only prevent relative imports in that module rather than causing
4119 all imports from that module to fail.
4120
Nick Coghlan14ff9942008-07-08 14:21:42 +00004121- Issue #2517: Allow unicode messages in Exceptions again by correctly

4131 another thread's dictionary.
4132
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004133- Issue #3004: Minor change to slice.indices(): the start and stop
4134 arguments are now treated identically, making the behaviour easier
4135 to describe and understand. For example, slice(None, -10,
4136 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4137 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4138 10, -1).
4139
Georg Brandl278fc502008-07-19 12:46:12 +00004140- Issue #3219: Calling a function with repeated keyword arguments,
4141 f(a=2, a=23), would not cause a syntax error. This was a regression
4142 from 2.4 caused by the switch to the new compiler.

4181 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004182 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004183 content-length. The problem had been corrected in the 2.4 branch, but never

4543 suitable sign) if n is large and negative; previously, it raised
4544 OverflowError.

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004590- On MacOS X it is now possible to install the framework in 64-bit
4591 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004592 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004593
4594 This is controlled by the configure argument ``--with-universal-archs``:
4595
4596 - ``--with-universal-archs=all``: install 4-way universal
4597
4598 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4599
4600 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4601
4602 This option should be used in combination with ``--enable-universalsdk=``.
4603
4604 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 +00004654- Issue #1631171: Re-implement the 'warnings' module in C (the
4655 original Python code has been kept as backup). This will allow for
4656 using the 'warning's machinery in such places as the parser where
4657 use of pure Python code is not possible. Both the ``showarning()``
4658 and ``formatwarning()`` gain an optional 'line' argument which is
4659 not called by default for backwards-compatibility reasons. Setting
4660 ``warnings.showwarning()`` to an implementation that lacks support
4661 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004724- Issue #2550: The approach used by client/server code for obtaining
4725 ports to listen on in network-oriented tests has been refined in an
4726 effort to facilitate running multiple instances of the entire
4727 regression test suite in parallel without issue.
4728 test_support.bind_port() has been fixed such that it will always
4729 return a unique port -- which wasn't always the case with the
4730 previous implementation, especially if socket options had been set
4731 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4732 new implementation of bind_port() will actually raise an exception
4733 if it is passed an AF_INET/SOCK_STREAM socket with either the
4734 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4735 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4736 the socket it's been passed. This currently only applies to
4737 Windows. This option prevents any other sockets from binding to the
4738 host/port we've bound to, thus removing the possibility of the
4739 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4740 when a second SOCK_STREAM socket binds and accepts to a host/port
4741 that's already been bound by another socket. The optional preferred
4742 port parameter to bind_port() has been removed. Under no
4743 circumstances should tests be hard coding ports!
4744
4745 test_support.find_unused_port() has also been introduced, which will
4746 pass a temporary socket object to bind_port() in order to obtain an
4747 unused port. The temporary socket object is then closed and
4748 deleted, and the port is returned. This method should only be used
4749 for obtaining an unused port in order to pass to an external program
4750 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4751 a parameter to a server-oriented class that doesn't give you direct
4752 access to the underlying socket used.
4753
4754 Finally, test_support.HOST has been introduced, which should be used
4755 for the host argument of any relevant socket calls (i.e. bind and
4756 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004757
4758 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004759 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004760 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4761 test_asynchat and test_socket_ssl.
4762
Georg Brandl3ee81df2008-05-17 18:14:43 +00004763 It is now possible for multiple instances of the regression test
4764 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00004818- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00004819 \Uxxxxxxxx did not accept values outside the Basic Multilingual
4820 Plane. This affected raw unicode literals and the
4821 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
4822 this case, like normal unicode literals and the 'unicode-escape'
4823 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00005043- Added the future_builtins module, which contains hex() and oct().
5044 These are the PEP 3127 version of these functions, designed to be
5045 compatible with the hex() and oct() builtins from Python 3.0. They
5046 differ slightly in their output formats from the existing, unchanged
5047 Python 2.6 builtins. The expected usage of the future_builtins
5048 module is:
5049 from future_builtins import hex, oct
5050
Eric Smith7ef40bf2008-02-20 23:34:22 +00005051- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5052 exponents for exponents with absolute value < 100. Follows C99
5053 standard. This is a change on Windows, which would use 3 digits.
5054 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5055 so that any alterations it does to the resulting string will be
5056 available in stringlib/formatter.h (for float.__format__).
5057
Eric Smith5a3c1352008-02-19 13:21:56 +00005058- Implemented PEP 3101, Advanced String Formatting. This adds a new
5059 builtin format(); a format() method for str and unicode; a
5060 __format__() method to object, str, unicode, int, long, float, and
5061 datetime; the class string.Formatter; and the C API
5062 PyObject_Format().
5063
Georg Brandl3ee81df2008-05-17 18:14:43 +00005064- Fixed several potential crashes, all caused by specially crafted
5065 __del__ methods exploiting objects in temporarily inconsistent
5066 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005067
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005068- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005069 prevent a possible crash: an Abstract Base Class would try to access
5070 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005071

Georg Brandl3ee81df2008-05-17 18:14:43 +00005075- Clear all free lists during a gc.collect() of the highest generation
5076 in order to allow pymalloc to free more arenas. Python may give back
5077 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005078
Georg Brandl3ee81df2008-05-17 18:14:43 +00005079- Issue #2045: Fix an infinite recursion triggered when printing a
5080 subclass of collections.defaultdict, if its default_factory is set
5081 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005082
Christian Heimesf75dbef2008-02-08 00:11:31 +00005083- Fixed a minor memory leak in dictobject.c. The content of the free
5084 list was not freed on interpreter shutdown.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005109- Patch #1473257: generator objects gain a gi_code attribute. This is
5110 the same object as the func_code attribute of the function that
5111 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005112
Georg Brandl3ee81df2008-05-17 18:14:43 +00005113- Issue #1920: "while 0" statements were completely removed by the
5114 compiler, even in the presence of an "else" clause, which is
5115 supposed to be run when the condition is false. Now the compiler
5116 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005117
Guido van Rossumeead05f2008-01-24 18:21:02 +00005118- A few crashers fixed: weakref_in_del.py (issue #1377858);
5119 loosing_dict_ref.py (issue #1303614, test67.py);
5120 borrowed_ref_[34].py (not in tracker).
5121
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005122- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005123 suppressed while an extension is loaded by calling SetErrorMode in
5124 dynload_win.c. The error is still reported properly.
5125
Georg Brandl3ee81df2008-05-17 18:14:43 +00005126- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005127 several extension methods and modules do not work without unicode
5128 support.
5129
Georg Brandl26543b12008-01-21 18:36:51 +00005130- Issue #1882: when compiling code from a string, encoding cookies in the

5134
Georg Brandl6caad7d2008-01-26 14:19:22 +00005135- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005136 added.
5137
Christian Heimesc94e2b52008-01-14 04:13:37 +00005138- sys.float_info / PyFloat_GetInfo: The floating point information
5139 object was converted from a dict to a specialized structseq object.
5140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- Patch #1816: Added sys.flags structseq. It exposes the status of
5142 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005143
Georg Brandl3ee81df2008-05-17 18:14:43 +00005144- Objects/structseq.c: Implemented new structseq representation. The
5145 patch makes structseqs (e.g. the return value of os.stat) more
5146 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005147
Georg Brandl3ee81df2008-05-17 18:14:43 +00005148- Patch #1700288: added a type attribute cache that caches method
5149 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005150
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005151- Bug #1776: __import__() no longer accepts filenames on any platform.
5152 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005153
Georg Brandlaed6c662008-01-07 17:25:53 +00005154- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5155
Georg Brandl3ee81df2008-05-17 18:14:43 +00005156- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5157 envvar and sys.dont_write_bytecode attribute. All these can be set
5158 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005159
Georg Brandl3ee81df2008-05-17 18:14:43 +00005160- Improve some exception messages when Windows fails to load an
5161 extension module. Now we get for example '%1 is not a valid Win32
5162 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005163

Christian Heimes0a8143f2007-12-18 23:22:54 +00005169- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005170 and INF. float("nan"), float("inf") and float("-inf") now work on
5171 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005172
Georg Brandl3ee81df2008-05-17 18:14:43 +00005173- Compiler now generates simpler and faster code for dictionary
5174 literals. The oparg for BUILD_MAP now indicates an estimated
5175 dictionary size. There is a new opcode, STORE_MAP, for adding
5176 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005205- Patch #1739468: Directories and zipfiles containing a __main__.py
5206 file can now be directly executed by passing their name to the
5207 interpreter. The directory/zipfile is automatically inserted as the
5208 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005209
Georg Brandl3ee81df2008-05-17 18:14:43 +00005210- Issue #1265: Fix a problem with sys.settrace, if the tracing
5211 function uses a generator expression when at the same time the
5212 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005213
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005214- sets and frozensets now have an isdisjoint() method.
5215
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005216- optimize the performance of builtin.sum().

5219
Georg Brandl21e99f42010-03-07 15:23:59 +00005220- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005221 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5222 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005223
Georg Brandl3ee81df2008-05-17 18:14:43 +00005224- Issue #1686386: Tuple's tp_repr did not take into account the
5225 possibility of having a self-referential tuple, which is possible
5226 from C code. Nor did object's tp_str consider that a type's tp_str
5227 could do something that could lead to an inifinite recursion.
5228 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5229 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005230
Georg Brandl3ee81df2008-05-17 18:14:43 +00005231- Issue #1164: It was possible to trigger deadlock when using the
5232 'print' statement to write to a file since the GIL was not released
5233 as needed. Now PyObject_Print() does the right thing along with
5234 various tp_print implementations of the built-in types and those in
5235 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005236
Georg Brandl3ee81df2008-05-17 18:14:43 +00005237- Issue #1147: Exceptions were directly allowing string exceptions in
5238 their throw() method even though string exceptions no longer
5239 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005240
Georg Brandl3ee81df2008-05-17 18:14:43 +00005241- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00005243
Brett Cannon1e534b52007-09-07 04:18:30 +00005244- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005245 PyObject_Call() never calling back out to Python code to trigger
5246 recursion depth updates/checks. Required the creation of a static
5247 RuntimeError instance in case normalizing an exception put the
5248 recursion check value past its limit. Fixes crashers
5249 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005250

Neal Norwitz0ac60192007-05-27 04:08:54 +00005264- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005265 __*__ attributes. (Some already existed, e.g., __doc__ and
5266 __name__.)

5272 calls.
5273
Collin Winter62903052007-05-18 23:11:24 +00005274- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005275 "except E as target:". This is to provide forwards compatibility
5276 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005280- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005281 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005282
Vinay Sajip8549ce32007-05-06 17:53:37 +00005283- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005284 setting a plain string, ie don't expand to single letter identifiers.
5285
Raymond Hettinger13936692007-04-11 18:40:58 +00005286- Request #1191699: Slices can now be pickled.
5287
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005288- Request #1193128: str.translate() now allows a None argument for
5289 translations that only remove characters without re-mapping the
5290 remaining characters.
5291
Georg Brandl5cb76c12007-03-21 09:00:39 +00005292- Patch #1682205: a TypeError while unpacking an iterable is no longer

5296
Guido van Rossum143b5642007-03-23 04:58:42 +00005297- Bug #1683368: The object.__init__() and object.__new__() methods are
5298 now stricter in rejecting excess arguments. The only time when
5299 either allows excess arguments is when it is not overridden and the
5300 other one is. For backwards compatibility, when both are
5301 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005302 warning later). Also, type.__init__() insists on the same signature
5303 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005305- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5306 object to complex using its __complex__() method before falling back
5307 to the __float__() method. Therefore, the functions in the cmath
5308 module now can operate on objects that define a __complex__()
5309 method.

5329
Georg Brandl871f1bc2007-03-12 13:17:36 +00005330- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005331 its argument, if it exists. If not, it will work like before. This
5332 allows customizing the output of dir() in the presence of a
5333 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00005345- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005346 makes the filenames the warning module prints much more sensible
5347 when a PYTHONSTARTUP file is used.

5362
Georg Brandl3ee81df2008-05-17 18:14:43 +00005363- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00005415- Bug #1545497: when given an explicit base, int() did ignore NULs
5416 embedded in the string to convert.
5417
Georg Brandl846f73a2006-10-08 07:11:54 +00005418- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00005466 generator expressions (x for x, in ... ) works again. Fixing this
5467 problem required changing the .pyc magic number. This means that
5468 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006271- The implementation of UnicodeError objects has been simplified
6272 (start and end attributes are now stored directly as Py_ssize_t
6273 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00006274
Georg Brandl3ee81df2008-05-17 18:14:43 +00006275- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6276 with RFC 3207 and forgets any knowledge obtained from the server not
6277 obtained from the TLS negotiation itself. Patch contributed by Bill
6278 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006279
Georg Brandl3ee81df2008-05-17 18:14:43 +00006280- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006281 that the SMTP.starttls() caller no longer needs to call ehlo()
6282 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006283 does not claim to support starttls. Adds the
6284 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6285 Fenner.

6365 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6366 silently miscode subclasses of those types. Now, it raises a
6367 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006368

Georg Brandl3ee81df2008-05-17 18:14:43 +00006383 time so that opening a database previously created with the DB_DUP
6384 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6385 opens. Specifically: dictionary assignment to a DB object will
6386 replace all values for a given key when the database allows
6387 duplicate values. DB users should use DB.put(k, v) when they want
6388 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006389

6395 characters with ASCII value less than 32. Also, it correctly quotes
6396 dots only if they occur on a single line, as opposed to the previous
6397 behavior of quoting dots if they are the second character of any
6398 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006399
