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

305 to fetch the original errno, or to filter timeout errors. Now the
306 original error is re-raised.

310 be updated back after the system call. Original patch by Brian Brazil.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000755- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
756 start byte and the continuation byte(s) are now considered invalid, instead
757 of the number of bytes specified by the start byte.
758 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
759 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
760 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

770 objects. (1) The comparison could incorrectly return True in some cases
771 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

914 non-float non-integer argument is now converted to an integer (if possible)
915 using its __int__ method. Previously, only small arguments were treated this
916 way; larger arguments (those whose __int__ was outside the range of a C long)
917 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00001156- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1157 with a non-empty format string. This is an effort to future-proof user
1158 code. If a derived class does not currently implement __format__ but later
1159 adds its own __format__, it would most likely break user code that had
1160 supplied a format string. This will be changed to a DeprecationWaring in
1161 Python 3.3 and it will be an error in Python 3.4.

1655 position to the given argument, which goes against the tradition of

1752
Georg Brandlba83f822010-03-14 09:50:54 +00001753- The ``__complex__()`` method is now looked up on the class of instances to
1754 make it consistent with other special methods.

1758
Mark Dickinson1b34d252010-01-01 17:27:30 +00001759- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001760 DeprecationWarning when passed a float argument where an integer was expected.
1761 These functions and methods now raise TypeError instead. The majority of the
1762 effects of this change are in the extension modules, but some core functions
1763 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1764 and many unicode/str methods.

1778 of integers: the result of a/b is now correctly rounded for ints a and b (at
1779 least on IEEE 754 platforms), and in particular does not depend on the
1780 internal representation of a long.

1788
Georg Brandlba83f822010-03-14 09:50:54 +00001789 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001947- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1948 decimal string that's guaranteed to round back to x under correct rounding
1949 (with round-half-to-even rounding mode). Previously it gave a string based on
1950 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1951 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1952 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001953
Georg Brandlba83f822010-03-14 09:50:54 +00001954- Issue #7117: On almost all platforms: float-to-string and string-to-float
1955 conversions within Python are now correctly rounded. Places these conversions
1956 occur include: str for floats and complex numbers; the float and complex
1957 constructors; old-style and new-style numeric formatting; serialization and
1958 deserialization of floats and complex numbers using marshal, pickle and json;
1959 parsing of float and imaginary literals in Python code; Decimal-to-float
1960 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001961
Georg Brandlba83f822010-03-14 09:50:54 +00001962 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1963 providing correctly-rounded strtod and dtoa C functions. This code is
1964 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1965 the C compiler. There may be a small number of platforms on which correct
1966 operation of this code cannot be guaranteed, so the code is not used: notably,
1967 this applies to platforms where the C double format is not IEEE 754 binary64,
1968 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1969 and Python's configure script is unable to determine how to change the FPU
1970 precision. On these platforms conversions use the platform strtod and dtoa,
1971 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001973- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1974 uses the correctly-rounded string <-> float conversions described above (when
1975 available), and so produces correctly rounded results that will display nicely
1976 under the float repr. There are two related small changes: (1) round now
1977 accepts any class with an ``__index__()`` method for its second argument (but
1978 no longer accepts floats for the second argument), and (2) an excessively
1979 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1980 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002123 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2124 (2) parsing of strings representing infinities and nans was locale aware; and
2125 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002127- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2128 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2129 but with at least one decimal point and with a default precision
2130 of 12. Previously, the behavior the same but with a default precision of 6.
2131 This more closely matches ``str()``, and reduces surprises when adding
2132 alignment flags to the empty presentation type. This also affects the new
2133 complex.__format__ in the same way.
2134
2135- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

2333 the file object behaves like a closed file. The ``FileIO`` object also got a

Walter Dörwalded960ac2009-05-03 22:36:33 +00002385- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2386 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2387 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2388 of using the replace error handler in PyUnicode_DecodeUTF8().
2389
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002390- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002393- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003761- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3762
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003763- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3764 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3765 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3766 ``printf`` function, whereas PyString_FromFormat has an independent
3767 implementation and uses "%zd" on all platforms for size_t values.
3768 This makes a difference on win64, where ``printf`` needs "%Id" to display
3769 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00003771- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3775 object; previously an int would be returned for small values. the __long__
3776 method is allowed to return either an int or a long, but the behaviour of
3777 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003779- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003786 was correctly parsed but parsing of subsequent arguments failed.
3787
Vinay Sajip35e3b032008-09-01 14:33:59 +00003788- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003789 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3790 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3791 when given a tuple of classes as second argument, were looking up
3792 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3793 type object.

3938-----------------
3939
Guido van Rossumf8402962008-08-20 15:01:50 +00003940- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3941 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3942 extensions do not automatically benefit from the class attribute
3943 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3944 to their tp_flags field if they care. This is a backwards
3945 compatibility feature; in 3.0, all types will use the cache by
3946 default.
3947
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003948- Keyword arguments can now follow starred arguments. (``f(a, *args,
3949 keyword=23)`` is now valid syntax.)
3950
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003951- ctypes function pointers that are COM methods have a boolean True
3952 value again.
3953
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003954- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3955 by denying s# to parse objects that have a releasebuffer procedure,
3956 and introducing s*.
3957
Georg Brandl1e13ea92008-08-11 09:07:59 +00003958- Issue #3537: Fix an assertion failure when an empty but presized dict
3959 object was stored in the freelist.
3960
Mark Dickinsonb6467572008-08-04 21:30:09 +00003961- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3962 ValueError consistently across platforms.
3963
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003964- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3965 (64bit Unix, for example), unichr() would truncate its argument and return
3966 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3967
Neal Norwitze7d8be82008-07-31 17:17:14 +00003968- Apply security patches from Apple.
3969
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003970- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

3972
Antoine Pitrou92f82162008-07-25 22:22:08 +00003973- Issue #1819: function calls with several named parameters are now on
3974 average 35% faster (as measured by pybench).
3975
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003976- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3977 the python debugger steps into a class statement: the free variables (local
3978 variables defined in an outer scope) would be deleted from the outer scope.
3979
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003980- Issue #2620: Overflow checking when allocating or reallocating memory
3981 was not always being done properly in some python types and extension
3982 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3983 all been updated to perform better checks and places in the code that
3984 would previously leak memory on the error path when such an allocation

3991
Benjamin Petersone977ad42008-08-20 01:42:01 +00003992- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3993 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3994
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003995- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3996 version reported by these tools does not necessarily follow the python
3997 version numbering scheme, so the module is less strict when parsing it.
3998
Nick Coghlanf70385a2008-08-18 12:42:46 +00003999- Issue #2235: Added Py3k warnings for types which will become unhashable
4000 under the stricter __hash__ inheritance rules in 3.0. Several types
4001 which did not meet the rules for hash invariants and were already
4002 unhashable in 3.0 have now been explicitly flagged as unhashable in
4003 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4004 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4005
Brett Cannon88f801d2008-08-18 00:46:22 +00004006- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4007 imported into the module but exposed as part of the module's API.
4008
Brett Cannon7b96f072008-08-18 00:41:11 +00004009- Remove an unneeded import of abc.ABCMeta from 'inspect'.

4014
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004015- Issue #3575: Incremental decoder's decode function now takes bytearray
4016 by using 's*' instead of 't#'.
4017
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004018- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004019 fails unicode conversion on 2nd parameter. (windows only)
4020
Georg Brandl222e2082010-08-01 22:27:39 +00004021- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004022 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +00004024- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004025 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004026
Facundo Batistaeb90b782008-08-16 14:44:07 +00004027- Issue #2776: fixed small issue when handling an URL with double slash
4028 after a 302 response in the case of not going through a proxy.
4029
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004030- Issue #2676: in the email package, content-type parsing was hanging on
4031 pathological input because of quadratic or exponential behaviour of a
4032 regular expression.
4033
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004034- Issue #3476: binary buffered reading through the new "io" library is now
4035 thread-safe.
4036
Brett Cannonbf3157b2008-08-14 05:00:03 +00004037- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4038 since mimetools itself is deprecated. Because modules are cached, all
4039 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4040
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004041- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00004043- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4044 menu entries were not deleted.
4045
Brett Cannon83e81842008-08-09 23:30:55 +00004046- Copied the implementation of reduce() to _functools.reduce() to have a
4047 version that did not raise a DeprecationWarning under -3.
4048
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004049- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4050 a MemoryError rather than silently stop the iteration.
4051
Guido van Rossum59ce9012008-08-09 14:55:34 +00004052- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4053 to _sre.compile() will now be rejected. This should not affect anybody
4054 since the re.compile() function never generates invalid re-bytecode.
4055
Skip Montanaroa032bf42008-08-08 22:52:51 +00004056- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4057 upon first access it can be automatically initialized from the csv file if
4058 it wasn't initialized during instantiation.
4059
Brett Cannon3aa2a492008-08-06 22:28:09 +00004060- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4061 the reload() built-in has been removed.
4062
Brett Cannon7e30b672008-08-04 21:52:25 +00004063- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004064 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4072 raised an AttributeError.
4073

Antoine Pitroude781a42008-08-09 12:43:23 +00004075 asking for a specific length. This problem only affected files opened
4076 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004077

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004101- Issue #3394: zipfile.writestr sets external attributes when passed a
4102 file name rather than a ZipInfo instance, so files are extracted with
4103 mode 0600 rather than 000 under Unix.
4104
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004105- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4106 argument in python 2.5, this broke code that subclassed Popen to include its
4107 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4118 interaction with the tp_hash slot (added in 2.6b2) are now documented
4119
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004120- Issue #643841: The language reference now provides more detailed
4121 coverage of the lookup process for special methods. The disclaimers
4122 regarding lack of coverage of new-style classes have also been
4123 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004131Core and Builtins
4132-----------------
4133
Georg Brandl3e483f62008-07-16 22:57:41 +00004134- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4135 its methods now allow for items objects that can be converted to
4136 an integer using operator.index().
4137
Mark Dickinson64b7e502008-07-16 09:40:03 +00004138- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4139 produced a ValueError instead of giving the correct float.
4140
Eric Smitha5fa5a22008-07-16 00:11:49 +00004141- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4142 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4143
Mark Dickinson7103aa42008-07-15 19:08:33 +00004144- Issue #3008: the float type has a new instance method 'float.hex'
4145 and a new class method 'float.fromhex' to convert floating-point
4146 numbers to and from hexadecimal strings, respectively.
4147
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004148- Issue #2235: __hash__ is once again inherited by default. To allow
4149 collections.Hashable to remain meaningful in the presence of the
4150 default hash implementation (object.__hash__), it is now possible
4151 to explicit block inheritance of hash by setting __hash__=None at
4152 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4153 level.
4154
Nick Coghlanb028f502008-07-13 14:52:36 +00004155- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4156 the parent module cannot be found while performing an absolute import.
4157 This means that an incorrectly defined __package__ attribute will
4158 now only prevent relative imports in that module rather than causing
4159 all imports from that module to fail.
4160
Nick Coghlan14ff9942008-07-08 14:21:42 +00004161- Issue #2517: Allow unicode messages in Exceptions again by correctly
4162 bypassing the instance dictionary when looking up __unicode__ on
4163 new-style classes.
4164
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004165- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4166 set to a custom object whose write() method happens to install
4167 another file in sys.stdout.
4168
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004169- Issue #3088: Corrected a race condition in classes derived from
4170 threading.local: the first member set by a thread could be saved in
4171 another thread's dictionary.
4172
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004173- Issue #3004: Minor change to slice.indices(): the start and stop
4174 arguments are now treated identically, making the behaviour easier
4175 to describe and understand. For example, slice(None, -10,
4176 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4177 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4178 10, -1).
4179
Georg Brandl278fc502008-07-19 12:46:12 +00004180- Issue #3219: Calling a function with repeated keyword arguments,
4181 f(a=2, a=23), would not cause a syntax error. This was a regression
4182 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004183
Georg Brandl278fc502008-07-19 12:46:12 +00004184- Issue #2862: Make int and float freelist management consistent with
4185 other freelists. Changes their CompactFreeList apis into
4186 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00004191- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4192 api functions without holding the GIL, which could lead to a fatal
4193 error when they failed.
4194
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004195- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004203- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4204 ForkingPickler.register() to resolve conflict with ctypes.
4205
Vinay Sajip51e65192008-07-18 09:01:10 +00004206- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00004208- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4209 a valid dlerror() message.
4210
Thomas Heller2bad6572008-07-15 17:19:50 +00004211- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4212 incomplete structure was created.
4213

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004218- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004219
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004220- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4221 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004222 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004223 content-length. The problem had been corrected in the 2.4 branch, but never
4224 merged into trunk.
4225

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004239- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4240 handling is now the same as that of other special attributes like __name__).
4241
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004242- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004630- On MacOS X it is now possible to install the framework in 64-bit
4631 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004632 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004633
4634 This is controlled by the configure argument ``--with-universal-archs``:
4635
4636 - ``--with-universal-archs=all``: install 4-way universal
4637
4638 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4639
4640 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4641
4642 This option should be used in combination with ``--enable-universalsdk=``.
4643
4644 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 +00004694- Issue #1631171: Re-implement the 'warnings' module in C (the
4695 original Python code has been kept as backup). This will allow for
4696 using the 'warning's machinery in such places as the parser where
4697 use of pure Python code is not possible. Both the ``showarning()``
4698 and ``formatwarning()`` gain an optional 'line' argument which is
4699 not called by default for backwards-compatibility reasons. Setting
4700 ``warnings.showwarning()`` to an implementation that lacks support
4701 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004764- Issue #2550: The approach used by client/server code for obtaining
4765 ports to listen on in network-oriented tests has been refined in an
4766 effort to facilitate running multiple instances of the entire
4767 regression test suite in parallel without issue.
4768 test_support.bind_port() has been fixed such that it will always
4769 return a unique port -- which wasn't always the case with the
4770 previous implementation, especially if socket options had been set
4771 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4772 new implementation of bind_port() will actually raise an exception
4773 if it is passed an AF_INET/SOCK_STREAM socket with either the
4774 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4775 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4776 the socket it's been passed. This currently only applies to
4777 Windows. This option prevents any other sockets from binding to the
4778 host/port we've bound to, thus removing the possibility of the
4779 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4780 when a second SOCK_STREAM socket binds and accepts to a host/port
4781 that's already been bound by another socket. The optional preferred
4782 port parameter to bind_port() has been removed. Under no
4783 circumstances should tests be hard coding ports!
4784
4785 test_support.find_unused_port() has also been introduced, which will
4786 pass a temporary socket object to bind_port() in order to obtain an
4787 unused port. The temporary socket object is then closed and
4788 deleted, and the port is returned. This method should only be used
4789 for obtaining an unused port in order to pass to an external program
4790 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4791 a parameter to a server-oriented class that doesn't give you direct
4792 access to the underlying socket used.
4793
4794 Finally, test_support.HOST has been introduced, which should be used
4795 for the host argument of any relevant socket calls (i.e. bind and
4796 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004797
4798 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004799 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004800 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4801 test_asynchat and test_socket_ssl.
4802
Georg Brandl3ee81df2008-05-17 18:14:43 +00004803 It is now possible for multiple instances of the regression test
4804 suite to run in parallel without issue.

5078- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005079
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005080- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005081 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005082
Eric Smitha73fbe72008-02-23 03:09:44 +00005083- Added the future_builtins module, which contains hex() and oct().
5084 These are the PEP 3127 version of these functions, designed to be
5085 compatible with the hex() and oct() builtins from Python 3.0. They
5086 differ slightly in their output formats from the existing, unchanged
5087 Python 2.6 builtins. The expected usage of the future_builtins
5088 module is:
5089 from future_builtins import hex, oct
5090
Eric Smith7ef40bf2008-02-20 23:34:22 +00005091- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5092 exponents for exponents with absolute value < 100. Follows C99
5093 standard. This is a change on Windows, which would use 3 digits.
5094 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5095 so that any alterations it does to the resulting string will be
5096 available in stringlib/formatter.h (for float.__format__).
5097
Eric Smith5a3c1352008-02-19 13:21:56 +00005098- Implemented PEP 3101, Advanced String Formatting. This adds a new
5099 builtin format(); a format() method for str and unicode; a
5100 __format__() method to object, str, unicode, int, long, float, and
5101 datetime; the class string.Formatter; and the C API
5102 PyObject_Format().
5103
Georg Brandl3ee81df2008-05-17 18:14:43 +00005104- Fixed several potential crashes, all caused by specially crafted
5105 __del__ methods exploiting objects in temporarily inconsistent
5106 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005107
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005108- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005109 prevent a possible crash: an Abstract Base Class would try to access
5110 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005111
Georg Brandl3ee81df2008-05-17 18:14:43 +00005112- Fixed repr() and str() of complex numbers with infinity or nan as
5113 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005114
Georg Brandl3ee81df2008-05-17 18:14:43 +00005115- Clear all free lists during a gc.collect() of the highest generation
5116 in order to allow pymalloc to free more arenas. Python may give back
5117 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005118
Georg Brandl3ee81df2008-05-17 18:14:43 +00005119- Issue #2045: Fix an infinite recursion triggered when printing a
5120 subclass of collections.defaultdict, if its default_factory is set
5121 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005122
Christian Heimesf75dbef2008-02-08 00:11:31 +00005123- Fixed a minor memory leak in dictobject.c. The content of the free
5124 list was not freed on interpreter shutdown.
5125
Georg Brandl21e99f42010-03-07 15:23:59 +00005126- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005127 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005128
Georg Brandl3ee81df2008-05-17 18:14:43 +00005129- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5130 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005131 to compact the internal free lists of pre-allocted ints and floats.
5132
Georg Brandl3ee81df2008-05-17 18:14:43 +00005133- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5134 calls. Python expected the return type int but the fork familie
5135 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005136
Georg Brandl3ee81df2008-05-17 18:14:43 +00005137- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5138 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005139
Georg Brandl3ee81df2008-05-17 18:14:43 +00005140- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5141 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00005142
Georg Brandl3ee81df2008-05-17 18:14:43 +00005143- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
5144 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00005145
Georg Brandl3ee81df2008-05-17 18:14:43 +00005146- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5147 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005148
Georg Brandl3ee81df2008-05-17 18:14:43 +00005149- Patch #1473257: generator objects gain a gi_code attribute. This is
5150 the same object as the func_code attribute of the function that
5151 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005152
Georg Brandl3ee81df2008-05-17 18:14:43 +00005153- Issue #1920: "while 0" statements were completely removed by the
5154 compiler, even in the presence of an "else" clause, which is
5155 supposed to be run when the condition is false. Now the compiler
5156 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005157
Guido van Rossumeead05f2008-01-24 18:21:02 +00005158- A few crashers fixed: weakref_in_del.py (issue #1377858);
5159 loosing_dict_ref.py (issue #1303614, test67.py);
5160 borrowed_ref_[34].py (not in tracker).
5161
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005162- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005163 suppressed while an extension is loaded by calling SetErrorMode in
5164 dynload_win.c. The error is still reported properly.
5165
Georg Brandl3ee81df2008-05-17 18:14:43 +00005166- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005167 several extension methods and modules do not work without unicode
5168 support.
5169
Georg Brandl26543b12008-01-21 18:36:51 +00005170- Issue #1882: when compiling code from a string, encoding cookies in the
5171 second line of code were not always recognized correctly.
5172
Georg Brandl14404b62008-01-19 19:27:05 +00005173- Issue #1679: "0x" was taken as a valid integer literal.
5174
Georg Brandl6caad7d2008-01-26 14:19:22 +00005175- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005176 added.
5177
Christian Heimesc94e2b52008-01-14 04:13:37 +00005178- sys.float_info / PyFloat_GetInfo: The floating point information
5179 object was converted from a dict to a specialized structseq object.
5180
Georg Brandl3ee81df2008-05-17 18:14:43 +00005181- Patch #1816: Added sys.flags structseq. It exposes the status of
5182 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005183
Georg Brandl3ee81df2008-05-17 18:14:43 +00005184- Objects/structseq.c: Implemented new structseq representation. The
5185 patch makes structseqs (e.g. the return value of os.stat) more
5186 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005187
Georg Brandl3ee81df2008-05-17 18:14:43 +00005188- Patch #1700288: added a type attribute cache that caches method
5189 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005190
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005191- Bug #1776: __import__() no longer accepts filenames on any platform.
5192 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00005194- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5195
Georg Brandl3ee81df2008-05-17 18:14:43 +00005196- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5197 envvar and sys.dont_write_bytecode attribute. All these can be set
5198 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005199
Georg Brandl3ee81df2008-05-17 18:14:43 +00005200- Improve some exception messages when Windows fails to load an
5201 extension module. Now we get for example '%1 is not a valid Win32
5202 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005209- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005210 and INF. float("nan"), float("inf") and float("-inf") now work on
5211 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005212
Georg Brandl3ee81df2008-05-17 18:14:43 +00005213- Compiler now generates simpler and faster code for dictionary
5214 literals. The oparg for BUILD_MAP now indicates an estimated
5215 dictionary size. There is a new opcode, STORE_MAP, for adding
5216 entries to the dictionary.

5259
Georg Brandl21e99f42010-03-07 15:23:59 +00005260- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005261 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5262 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005263
Georg Brandl3ee81df2008-05-17 18:14:43 +00005264- Issue #1686386: Tuple's tp_repr did not take into account the
5265 possibility of having a self-referential tuple, which is possible
5266 from C code. Nor did object's tp_str consider that a type's tp_str
5267 could do something that could lead to an inifinite recursion.
5268 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5269 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005270
Georg Brandl3ee81df2008-05-17 18:14:43 +00005271- Issue #1164: It was possible to trigger deadlock when using the
5272 'print' statement to write to a file since the GIL was not released
5273 as needed. Now PyObject_Print() does the right thing along with
5274 various tp_print implementations of the built-in types and those in
5275 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005276
Georg Brandl3ee81df2008-05-17 18:14:43 +00005277- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00005284- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005285 PyObject_Call() never calling back out to Python code to trigger
5286 recursion depth updates/checks. Required the creation of a static
5287 RuntimeError instance in case normalizing an exception put the
5288 recursion check value past its limit. Fixes crashers

5312 calls.
5313
Collin Winter62903052007-05-18 23:11:24 +00005314- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005315 "except E as target:". This is to provide forwards compatibility
5316 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005320- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005321 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005323- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005324 setting a plain string, ie don't expand to single letter identifiers.
5325
Raymond Hettinger13936692007-04-11 18:40:58 +00005326- Request #1191699: Slices can now be pickled.
5327

5336
Guido van Rossum143b5642007-03-23 04:58:42 +00005337- Bug #1683368: The object.__init__() and object.__new__() methods are
5338 now stricter in rejecting excess arguments. The only time when
5339 either allows excess arguments is when it is not overridden and the
5340 other one is. For backwards compatibility, when both are
5341 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005342 warning later). Also, type.__init__() insists on the same signature
5343 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005344
Georg Brandl3ee81df2008-05-17 18:14:43 +00005345- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5346 object to complex using its __complex__() method before falling back
5347 to the __float__() method. Therefore, the functions in the cmath
5348 module now can operate on objects that define a __complex__()
5349 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005367- Bug #1678647: write a newline after printing an exception in any
5368 case, even when converting the value to a string failed.
5369
Georg Brandl871f1bc2007-03-12 13:17:36 +00005370- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005371 its argument, if it exists. If not, it will work like before. This
5372 allows customizing the output of dir() in the presence of a
5373 __getattr__().

5382 parthensized forms. This means complex(repr(x)) now works instead of
5383 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005384
Georg Brandlaa2321b2007-03-07 00:40:28 +00005385- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005386 makes the filenames the warning module prints much more sensible
5387 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005388

Georg Brandl0fca97a2007-03-05 22:28:08 +00005400- Patch #1674228: when assigning a slice (old-style), check for the
5401 sq_ass_slice instead of the sq_slice slot.
5402
Georg Brandl3ee81df2008-05-17 18:14:43 +00005403- When printing an unraisable error, don't print exceptions. before
5404 the name. This duplicates the behavior whening normally printing
5405 exceptions.

5456 embedded in the string to convert.
5457
Georg Brandl846f73a2006-10-08 07:11:54 +00005458- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00005506 generator expressions (x for x, in ... ) works again. Fixing this
5507 problem required changing the .pyc magic number. This means that
5508 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006315- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6316 with RFC 3207 and forgets any knowledge obtained from the server not
6317 obtained from the TLS negotiation itself. Patch contributed by Bill
6318 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006319
Georg Brandl3ee81df2008-05-17 18:14:43 +00006320- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006321 that the SMTP.starttls() caller no longer needs to call ehlo()
6322 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006323 does not claim to support starttls. Adds the
6324 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6325 Fenner.

6405 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6406 silently miscode subclasses of those types. Now, it raises a
6407 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006408

Georg Brandl3ee81df2008-05-17 18:14:43 +00006423 time so that opening a database previously created with the DB_DUP
6424 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6425 opens. Specifically: dictionary assignment to a DB object will
6426 replace all values for a given key when the database allows
6427 duplicate values. DB users should use DB.put(k, v) when they want
6428 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006429

6435 characters with ASCII value less than 32. Also, it correctly quotes
6436 dots only if they occur on a single line, as opposed to the previous
6437 behavior of quoting dots if they are the second character of any
6438 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006439

Georg Brandl3ee81df2008-05-17 18:14:43 +00006844- Removed the macfs module. It had been deprecated since Python 2.5.
6845 This lead to the deprecation of macostools.touched() as it relied
6846 solely on macfs and was a no-op under OS X.
