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

288 GC collection rather than freeing memory immediately when the refcnt drops
289 to zero.

298 original error is re-raised.

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

308 ConfigParser.write.
309
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000310- Issue #808164: Fixed socket.close to avoid references to globals, to

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000747- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
748 start byte and the continuation byte(s) are now considered invalid, instead
749 of the number of bytes specified by the start byte.
750 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
751 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
752 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

762 objects. (1) The comparison could incorrectly return True in some cases
763 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00001148- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1149 with a non-empty format string. This is an effort to future-proof user
1150 code. If a derived class does not currently implement __format__ but later
1151 adds its own __format__, it would most likely break user code that had
1152 supplied a format string. This will be changed to a DeprecationWaring in
1153 Python 3.3 and it will be an error in Python 3.4.

1227 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1228 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001639 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001640 Also, raise ValueError rather than TypeError when an unknown TIPC address

Georg Brandlba83f822010-03-14 09:50:54 +00001646 file position when calling `truncate()`. It would previously change the file
1647 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001648 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1651 class used to represent files stored inside an archive. The new
1652 implementation is significantly faster and can be wrapped in a
1653 ``io.BufferedReader`` object for more speedups. It also solves an issue
1654 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001665- Issue #7748: Since unicode values are supported for some metadata options in
1666 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1667 encoded string for them. This ensures that the upload and register commands
1668 send the correct values to PyPI without any error.

1743-----------------
1744
Georg Brandlba83f822010-03-14 09:50:54 +00001745- The ``__complex__()`` method is now looked up on the class of instances to
1746 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001748- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1749 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1750
Mark Dickinson1b34d252010-01-01 17:27:30 +00001751- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001752 DeprecationWarning when passed a float argument where an integer was expected.
1753 These functions and methods now raise TypeError instead. The majority of the
1754 effects of this change are in the extension modules, but some core functions
1755 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1756 and many unicode/str methods.

1770 of integers: the result of a/b is now correctly rounded for ints a and b (at
1771 least on IEEE 754 platforms), and in particular does not depend on the
1772 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001779 executables on OSX.
1780
Georg Brandlba83f822010-03-14 09:50:54 +00001781 These executables now work properly with the arch(1) command: ``arch -ppc
1782 python`` will start a universal binary version of python in PPC mode (unlike
1783 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001939- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1940 decimal string that's guaranteed to round back to x under correct rounding
1941 (with round-half-to-even rounding mode). Previously it gave a string based on
1942 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1943 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1944 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001945
Georg Brandlba83f822010-03-14 09:50:54 +00001946- Issue #7117: On almost all platforms: float-to-string and string-to-float
1947 conversions within Python are now correctly rounded. Places these conversions
1948 occur include: str for floats and complex numbers; the float and complex
1949 constructors; old-style and new-style numeric formatting; serialization and
1950 deserialization of floats and complex numbers using marshal, pickle and json;
1951 parsing of float and imaginary literals in Python code; Decimal-to-float
1952 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001953
Georg Brandlba83f822010-03-14 09:50:54 +00001954 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1955 providing correctly-rounded strtod and dtoa C functions. This code is
1956 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1957 the C compiler. There may be a small number of platforms on which correct
1958 operation of this code cannot be guaranteed, so the code is not used: notably,
1959 this applies to platforms where the C double format is not IEEE 754 binary64,
1960 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1961 and Python's configure script is unable to determine how to change the FPU
1962 precision. On these platforms conversions use the platform strtod and dtoa,
1963 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001965- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1966 uses the correctly-rounded string <-> float conversions described above (when
1967 available), and so produces correctly rounded results that will display nicely
1968 under the float repr. There are two related small changes: (1) round now
1969 accepts any class with an ``__index__()`` method for its second argument (but
1970 no longer accepts floats for the second argument), and (2) an excessively
1971 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1972 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002115 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2116 (2) parsing of strings representing infinities and nans was locale aware; and
2117 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002119- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2120 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2121 but with at least one decimal point and with a default precision
2122 of 12. Previously, the behavior the same but with a default precision of 6.
2123 This more closely matches ``str()``, and reduces surprises when adding
2124 alignment flags to the empty presentation type. This also affects the new
2125 complex.__format__ in the same way.
2126
2127- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00002323- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2324 file objects with closefd=False. The file descriptor is still kept open but
2325 the file object behaves like a closed file. The ``FileIO`` object also got a

2351 this code path is really executed because I cannot move to such directory on

Walter Dörwalded960ac2009-05-03 22:36:33 +00002377- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2378 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2379 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2380 of using the replace error handler in PyUnicode_DecodeUTF8().
2381
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002382- Issue #3739: The unicode-internal encoder now reports the number of characters

2384
Georg Brandlba83f822010-03-14 09:50:54 +00002385- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2387 gives improved memory leak detection when running under Valgrind, while taking
2388 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003753- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3754
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003755- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3756 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3757 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3758 ``printf`` function, whereas PyString_FromFormat has an independent
3759 implementation and uses "%zd" on all platforms for size_t values.
3760 This makes a difference on win64, where ``printf`` needs "%Id" to display
3761 64bit values.
3762
Benjamin Peterson97179b02008-09-09 20:55:01 +00003763- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3767 object; previously an int would be returned for small values. the __long__
3768 method is allowed to return either an int or a long, but the behaviour of
3769 float objects should not change to respect backward compatibility.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003780- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003781 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3782 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3783 when given a tuple of classes as second argument, were looking up
3784 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3785 type object.

3930-----------------
3931
Guido van Rossumf8402962008-08-20 15:01:50 +00003932- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3933 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3934 extensions do not automatically benefit from the class attribute
3935 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3936 to their tp_flags field if they care. This is a backwards
3937 compatibility feature; in 3.0, all types will use the cache by
3938 default.
3939
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003940- Keyword arguments can now follow starred arguments. (``f(a, *args,
3941 keyword=23)`` is now valid syntax.)
3942
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003943- ctypes function pointers that are COM methods have a boolean True
3944 value again.
3945
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003946- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,

3948 and introducing s*.
3949
Georg Brandl1e13ea92008-08-11 09:07:59 +00003950- Issue #3537: Fix an assertion failure when an empty but presized dict
3951 object was stored in the freelist.
3952
Mark Dickinsonb6467572008-08-04 21:30:09 +00003953- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3954 ValueError consistently across platforms.
3955
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003956- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3957 (64bit Unix, for example), unichr() would truncate its argument and return
3958 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

3964
Antoine Pitrou92f82162008-07-25 22:22:08 +00003965- Issue #1819: function calls with several named parameters are now on
3966 average 35% faster (as measured by pybench).
3967
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003968- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3969 the python debugger steps into a class statement: the free variables (local
3970 variables defined in an outer scope) would be deleted from the outer scope.
3971
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003972- Issue #2620: Overflow checking when allocating or reallocating memory
3973 was not always being done properly in some python types and extension
3974 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3975 all been updated to perform better checks and places in the code that
3976 would previously leak memory on the error path when such an allocation

3983
Benjamin Petersone977ad42008-08-20 01:42:01 +00003984- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3985 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3986
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003987- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3988 version reported by these tools does not necessarily follow the python
3989 version numbering scheme, so the module is less strict when parsing it.
3990
Nick Coghlanf70385a2008-08-18 12:42:46 +00003991- Issue #2235: Added Py3k warnings for types which will become unhashable
3992 under the stricter __hash__ inheritance rules in 3.0. Several types
3993 which did not meet the rules for hash invariants and were already
3994 unhashable in 3.0 have now been explicitly flagged as unhashable in
3995 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3996 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3997
Brett Cannon88f801d2008-08-18 00:46:22 +00003998- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3999 imported into the module but exposed as part of the module's API.
4000
Brett Cannon7b96f072008-08-18 00:41:11 +00004001- Remove an unneeded import of abc.ABCMeta from 'inspect'.

4006
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004007- Issue #3575: Incremental decoder's decode function now takes bytearray
4008 by using 's*' instead of 't#'.
4009
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004010- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004011 fails unicode conversion on 2nd parameter. (windows only)
4012
Georg Brandl222e2082010-08-01 22:27:39 +00004013- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004014 in a redirect.
4015
Brett Cannonabe423e2008-08-16 21:47:07 +00004016- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004017 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004018
Facundo Batistaeb90b782008-08-16 14:44:07 +00004019- Issue #2776: fixed small issue when handling an URL with double slash
4020 after a 302 response in the case of not going through a proxy.
4021
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004022- Issue #2676: in the email package, content-type parsing was hanging on
4023 pathological input because of quadratic or exponential behaviour of a
4024 regular expression.
4025
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004026- Issue #3476: binary buffered reading through the new "io" library is now
4027 thread-safe.
4028
Brett Cannonbf3157b2008-08-14 05:00:03 +00004029- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4030 since mimetools itself is deprecated. Because modules are cached, all
4031 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4032
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004033- Issue #3134: shutil referenced undefined WindowsError symbol.
4034
Robert Schuppenies14646332008-08-10 11:01:53 +00004035- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4036 menu entries were not deleted.
4037
Brett Cannon83e81842008-08-09 23:30:55 +00004038- Copied the implementation of reduce() to _functools.reduce() to have a
4039 version that did not raise a DeprecationWarning under -3.
4040
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004041- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4042 a MemoryError rather than silently stop the iteration.
4043
Guido van Rossum59ce9012008-08-09 14:55:34 +00004044- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4045 to _sre.compile() will now be rejected. This should not affect anybody
4046 since the re.compile() function never generates invalid re-bytecode.
4047
Skip Montanaroa032bf42008-08-08 22:52:51 +00004048- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4049 upon first access it can be automatically initialized from the csv file if
4050 it wasn't initialized during instantiation.
4051
Brett Cannon3aa2a492008-08-06 22:28:09 +00004052- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4053 the reload() built-in has been removed.
4054
Brett Cannon7e30b672008-08-04 21:52:25 +00004055- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004056 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

4064 raised an AttributeError.
4065
Benjamin Peterson01a24322008-07-28 23:35:27 +00004066- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004067 asking for a specific length. This problem only affected files opened
4068 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004069
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004070- Issue #3449: Update decimal module to use most recent specification
4071 (v. 1.68) and tests (v. 2.58) from IBM.
4072

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004093- Issue #3394: zipfile.writestr sets external attributes when passed a
4094 file name rather than a ZipInfo instance, so files are extracted with
4095 mode 0600 rather than 000 under Unix.
4096
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004097- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4098 argument in python 2.5, this broke code that subclassed Popen to include its
4099 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4110 interaction with the tp_hash slot (added in 2.6b2) are now documented
4111
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004112- Issue #643841: The language reference now provides more detailed
4113 coverage of the lookup process for special methods. The disclaimers
4114 regarding lack of coverage of new-style classes have also been
4115 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004123Core and Builtins
4124-----------------
4125
Georg Brandl3e483f62008-07-16 22:57:41 +00004126- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4127 its methods now allow for items objects that can be converted to
4128 an integer using operator.index().
4129
Mark Dickinson64b7e502008-07-16 09:40:03 +00004130- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4131 produced a ValueError instead of giving the correct float.
4132
Eric Smitha5fa5a22008-07-16 00:11:49 +00004133- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4134 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4135
Mark Dickinson7103aa42008-07-15 19:08:33 +00004136- Issue #3008: the float type has a new instance method 'float.hex'
4137 and a new class method 'float.fromhex' to convert floating-point
4138 numbers to and from hexadecimal strings, respectively.
4139
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004140- Issue #2235: __hash__ is once again inherited by default. To allow
4141 collections.Hashable to remain meaningful in the presence of the
4142 default hash implementation (object.__hash__), it is now possible
4143 to explicit block inheritance of hash by setting __hash__=None at
4144 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4145 level.
4146
Nick Coghlanb028f502008-07-13 14:52:36 +00004147- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4148 the parent module cannot be found while performing an absolute import.
4149 This means that an incorrectly defined __package__ attribute will
4150 now only prevent relative imports in that module rather than causing
4151 all imports from that module to fail.
4152
Nick Coghlan14ff9942008-07-08 14:21:42 +00004153- Issue #2517: Allow unicode messages in Exceptions again by correctly
4154 bypassing the instance dictionary when looking up __unicode__ on
4155 new-style classes.
4156
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004157- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4158 set to a custom object whose write() method happens to install
4159 another file in sys.stdout.
4160
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004161- Issue #3088: Corrected a race condition in classes derived from
4162 threading.local: the first member set by a thread could be saved in
4163 another thread's dictionary.
4164
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004165- Issue #3004: Minor change to slice.indices(): the start and stop
4166 arguments are now treated identically, making the behaviour easier
4167 to describe and understand. For example, slice(None, -10,
4168 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4169 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4170 10, -1).
4171
Georg Brandl278fc502008-07-19 12:46:12 +00004172- Issue #3219: Calling a function with repeated keyword arguments,
4173 f(a=2, a=23), would not cause a syntax error. This was a regression
4174 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004175
Georg Brandl278fc502008-07-19 12:46:12 +00004176- Issue #2862: Make int and float freelist management consistent with
4177 other freelists. Changes their CompactFreeList apis into
4178 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004179

4181-------
4182
Thomas Heller57adf222008-08-14 19:10:48 +00004183- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4184 api functions without holding the GIL, which could lead to a fatal
4185 error when they failed.
4186
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004187- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00004195- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4196 ForkingPickler.register() to resolve conflict with ctypes.
4197
Vinay Sajip51e65192008-07-18 09:01:10 +00004198- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004199
Thomas Heller880f5292008-07-15 19:39:38 +00004200- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4201 a valid dlerror() message.
4202
Thomas Heller2bad6572008-07-15 17:19:50 +00004203- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4204 incomplete structure was created.
4205

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004210- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004211
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004212- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4213 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004214 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004215 content-length. The problem had been corrected in the 2.4 branch, but never
4216 merged into trunk.
4217

Facundo Batista66c52772008-07-02 16:52:55 +00004230
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004231- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4232 handling is now the same as that of other special attributes like __name__).
4233
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004234- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4235 removal in Python 3.0 in favor of urllib2.urlopen().

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004622- On MacOS X it is now possible to install the framework in 64-bit
4623 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004624 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004625
4626 This is controlled by the configure argument ``--with-universal-archs``:
4627
4628 - ``--with-universal-archs=all``: install 4-way universal
4629
4630 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4631
4632 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4633
4634 This option should be used in combination with ``--enable-universalsdk=``.
4635
4636 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 +00004686- Issue #1631171: Re-implement the 'warnings' module in C (the
4687 original Python code has been kept as backup). This will allow for
4688 using the 'warning's machinery in such places as the parser where
4689 use of pure Python code is not possible. Both the ``showarning()``
4690 and ``formatwarning()`` gain an optional 'line' argument which is
4691 not called by default for backwards-compatibility reasons. Setting
4692 ``warnings.showwarning()`` to an implementation that lacks support
4693 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004756- Issue #2550: The approach used by client/server code for obtaining
4757 ports to listen on in network-oriented tests has been refined in an
4758 effort to facilitate running multiple instances of the entire
4759 regression test suite in parallel without issue.
4760 test_support.bind_port() has been fixed such that it will always
4761 return a unique port -- which wasn't always the case with the
4762 previous implementation, especially if socket options had been set
4763 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4764 new implementation of bind_port() will actually raise an exception
4765 if it is passed an AF_INET/SOCK_STREAM socket with either the
4766 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4767 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4768 the socket it's been passed. This currently only applies to
4769 Windows. This option prevents any other sockets from binding to the
4770 host/port we've bound to, thus removing the possibility of the
4771 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4772 when a second SOCK_STREAM socket binds and accepts to a host/port
4773 that's already been bound by another socket. The optional preferred
4774 port parameter to bind_port() has been removed. Under no
4775 circumstances should tests be hard coding ports!
4776
4777 test_support.find_unused_port() has also been introduced, which will
4778 pass a temporary socket object to bind_port() in order to obtain an
4779 unused port. The temporary socket object is then closed and
4780 deleted, and the port is returned. This method should only be used
4781 for obtaining an unused port in order to pass to an external program
4782 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4783 a parameter to a server-oriented class that doesn't give you direct
4784 access to the underlying socket used.
4785
4786 Finally, test_support.HOST has been introduced, which should be used
4787 for the host argument of any relevant socket calls (i.e. bind and
4788 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004789
4790 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004791 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004792 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4793 test_asynchat and test_socket_ssl.
4794
Georg Brandl3ee81df2008-05-17 18:14:43 +00004795 It is now possible for multiple instances of the regression test
4796 suite to run in parallel without issue.

5070- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005071
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005072- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005073 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005074
Eric Smitha73fbe72008-02-23 03:09:44 +00005075- Added the future_builtins module, which contains hex() and oct().
5076 These are the PEP 3127 version of these functions, designed to be
5077 compatible with the hex() and oct() builtins from Python 3.0. They
5078 differ slightly in their output formats from the existing, unchanged
5079 Python 2.6 builtins. The expected usage of the future_builtins
5080 module is:
5081 from future_builtins import hex, oct
5082
Eric Smith7ef40bf2008-02-20 23:34:22 +00005083- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5084 exponents for exponents with absolute value < 100. Follows C99
5085 standard. This is a change on Windows, which would use 3 digits.
5086 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5087 so that any alterations it does to the resulting string will be
5088 available in stringlib/formatter.h (for float.__format__).
5089
Eric Smith5a3c1352008-02-19 13:21:56 +00005090- Implemented PEP 3101, Advanced String Formatting. This adds a new
5091 builtin format(); a format() method for str and unicode; a
5092 __format__() method to object, str, unicode, int, long, float, and
5093 datetime; the class string.Formatter; and the C API
5094 PyObject_Format().
5095
Georg Brandl3ee81df2008-05-17 18:14:43 +00005096- Fixed several potential crashes, all caused by specially crafted
5097 __del__ methods exploiting objects in temporarily inconsistent
5098 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005099
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005100- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005101 prevent a possible crash: an Abstract Base Class would try to access
5102 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005103
Georg Brandl3ee81df2008-05-17 18:14:43 +00005104- Fixed repr() and str() of complex numbers with infinity or nan as
5105 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005106
Georg Brandl3ee81df2008-05-17 18:14:43 +00005107- Clear all free lists during a gc.collect() of the highest generation
5108 in order to allow pymalloc to free more arenas. Python may give back
5109 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005110
Georg Brandl3ee81df2008-05-17 18:14:43 +00005111- Issue #2045: Fix an infinite recursion triggered when printing a
5112 subclass of collections.defaultdict, if its default_factory is set
5113 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005114
Christian Heimesf75dbef2008-02-08 00:11:31 +00005115- Fixed a minor memory leak in dictobject.c. The content of the free
5116 list was not freed on interpreter shutdown.
5117
Georg Brandl21e99f42010-03-07 15:23:59 +00005118- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005119 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005120
Georg Brandl3ee81df2008-05-17 18:14:43 +00005121- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5122 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005123 to compact the internal free lists of pre-allocted ints and floats.
5124
Georg Brandl3ee81df2008-05-17 18:14:43 +00005125- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5126 calls. Python expected the return type int but the fork familie
5127 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005128
Georg Brandl3ee81df2008-05-17 18:14:43 +00005129- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5130 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005138- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5139 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005140
Georg Brandl3ee81df2008-05-17 18:14:43 +00005141- Patch #1473257: generator objects gain a gi_code attribute. This is
5142 the same object as the func_code attribute of the function that
5143 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005144
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145- Issue #1920: "while 0" statements were completely removed by the
5146 compiler, even in the presence of an "else" clause, which is
5147 supposed to be run when the condition is false. Now the compiler
5148 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005149
Guido van Rossumeead05f2008-01-24 18:21:02 +00005150- A few crashers fixed: weakref_in_del.py (issue #1377858);
5151 loosing_dict_ref.py (issue #1303614, test67.py);
5152 borrowed_ref_[34].py (not in tracker).
5153
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005154- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005155 suppressed while an extension is loaded by calling SetErrorMode in
5156 dynload_win.c. The error is still reported properly.
5157
Georg Brandl3ee81df2008-05-17 18:14:43 +00005158- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005159 several extension methods and modules do not work without unicode
5160 support.
5161
Georg Brandl26543b12008-01-21 18:36:51 +00005162- Issue #1882: when compiling code from a string, encoding cookies in the
5163 second line of code were not always recognized correctly.
5164

5166
Georg Brandl6caad7d2008-01-26 14:19:22 +00005167- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005168 added.
5169
Christian Heimesc94e2b52008-01-14 04:13:37 +00005170- sys.float_info / PyFloat_GetInfo: The floating point information
5171 object was converted from a dict to a specialized structseq object.
5172
Georg Brandl3ee81df2008-05-17 18:14:43 +00005173- Patch #1816: Added sys.flags structseq. It exposes the status of
5174 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005175
Georg Brandl3ee81df2008-05-17 18:14:43 +00005176- Objects/structseq.c: Implemented new structseq representation. The
5177 patch makes structseqs (e.g. the return value of os.stat) more
5178 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005179
Georg Brandl3ee81df2008-05-17 18:14:43 +00005180- Patch #1700288: added a type attribute cache that caches method
5181 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005182
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005183- Bug #1776: __import__() no longer accepts filenames on any platform.

Georg Brandlaed6c662008-01-07 17:25:53 +00005186- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5187
Georg Brandl3ee81df2008-05-17 18:14:43 +00005188- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5189 envvar and sys.dont_write_bytecode attribute. All these can be set
5190 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005191
Georg Brandl3ee81df2008-05-17 18:14:43 +00005192- Improve some exception messages when Windows fails to load an
5193 extension module. Now we get for example '%1 is not a valid Win32
5194 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005201- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005202 and INF. float("nan"), float("inf") and float("-inf") now work on
5203 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005204
Georg Brandl3ee81df2008-05-17 18:14:43 +00005205- Compiler now generates simpler and faster code for dictionary
5206 literals. The oparg for BUILD_MAP now indicates an estimated
5207 dictionary size. There is a new opcode, STORE_MAP, for adding
5208 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005242- Issue #1265: Fix a problem with sys.settrace, if the tracing
5243 function uses a generator expression when at the same time the
5244 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005245
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005246- sets and frozensets now have an isdisjoint() method.

5251
Georg Brandl21e99f42010-03-07 15:23:59 +00005252- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005253 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5254 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005255
Georg Brandl3ee81df2008-05-17 18:14:43 +00005256- Issue #1686386: Tuple's tp_repr did not take into account the
5257 possibility of having a self-referential tuple, which is possible
5258 from C code. Nor did object's tp_str consider that a type's tp_str
5259 could do something that could lead to an inifinite recursion.
5260 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5261 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005262
Georg Brandl3ee81df2008-05-17 18:14:43 +00005263- Issue #1164: It was possible to trigger deadlock when using the
5264 'print' statement to write to a file since the GIL was not released
5265 as needed. Now PyObject_Print() does the right thing along with
5266 various tp_print implementations of the built-in types and those in
5267 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005268
Georg Brandl3ee81df2008-05-17 18:14:43 +00005269- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00005276- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005277 PyObject_Call() never calling back out to Python code to trigger
5278 recursion depth updates/checks. Required the creation of a static
5279 RuntimeError instance in case normalizing an exception put the
5280 recursion check value past its limit. Fixes crashers

5302
Georg Brandl2134e752007-05-21 20:34:16 +00005303- Patch #1686487: you can now pass any mapping after '**' in function
5304 calls.
5305
Collin Winter62903052007-05-18 23:11:24 +00005306- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005307 "except E as target:". This is to provide forwards compatibility
5308 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005312- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005313 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005315- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005316 setting a plain string, ie don't expand to single letter identifiers.
5317
Raymond Hettinger13936692007-04-11 18:40:58 +00005318- Request #1191699: Slices can now be pickled.
5319
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005320- Request #1193128: str.translate() now allows a None argument for

5328
Guido van Rossum143b5642007-03-23 04:58:42 +00005329- Bug #1683368: The object.__init__() and object.__new__() methods are
5330 now stricter in rejecting excess arguments. The only time when
5331 either allows excess arguments is when it is not overridden and the
5332 other one is. For backwards compatibility, when both are
5333 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005334 warning later). Also, type.__init__() insists on the same signature
5335 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005336
Georg Brandl3ee81df2008-05-17 18:14:43 +00005337- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5338 object to complex using its __complex__() method before falling back
5339 to the __float__() method. Therefore, the functions in the cmath
5340 module now can operate on objects that define a __complex__()
5341 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005359- Bug #1678647: write a newline after printing an exception in any
5360 case, even when converting the value to a string failed.
5361
Georg Brandl871f1bc2007-03-12 13:17:36 +00005362- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005363 its argument, if it exists. If not, it will work like before. This
5364 allows customizing the output of dir() in the presence of a
5365 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00005367- Patch #922167: Python no longer segfaults when faced with infinitely
5368 self-recursive reload() calls (as reported by bug #742342).

5374 parthensized forms. This means complex(repr(x)) now works instead of
5375 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005376
Georg Brandlaa2321b2007-03-07 00:40:28 +00005377- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005378 makes the filenames the warning module prints much more sensible
5379 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005380

Georg Brandl0fca97a2007-03-05 22:28:08 +00005392- Patch #1674228: when assigning a slice (old-style), check for the
5393 sq_ass_slice instead of the sq_slice slot.
5394
Georg Brandl3ee81df2008-05-17 18:14:43 +00005395- When printing an unraisable error, don't print exceptions. before
5396 the name. This duplicates the behavior whening normally printing
5397 exceptions.

5406 created a weakref on itself during a __del__ call for new-style
5407 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00005447- Bug #1545497: when given an explicit base, int() did ignore NULs
5448 embedded in the string to convert.
5449
Georg Brandl846f73a2006-10-08 07:11:54 +00005450- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00005498 generator expressions (x for x, in ... ) works again. Fixing this
5499 problem required changing the .pyc magic number. This means that
5500 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006307- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6308 with RFC 3207 and forgets any knowledge obtained from the server not
6309 obtained from the TLS negotiation itself. Patch contributed by Bill
6310 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006311
Georg Brandl3ee81df2008-05-17 18:14:43 +00006312- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006313 that the SMTP.starttls() caller no longer needs to call ehlo()
6314 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006315 does not claim to support starttls. Adds the
6316 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6317 Fenner.

6397 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6398 silently miscode subclasses of those types. Now, it raises a
6399 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006400

Georg Brandl3ee81df2008-05-17 18:14:43 +00006415 time so that opening a database previously created with the DB_DUP
6416 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6417 opens. Specifically: dictionary assignment to a DB object will
6418 replace all values for a given key when the database allows
6419 duplicate values. DB users should use DB.put(k, v) when they want
6420 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006421

6427 characters with ASCII value less than 32. Also, it correctly quotes
6428 dots only if they occur on a single line, as opposed to the previous
6429 behavior of quoting dots if they are the second character of any
6430 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006431

Georg Brandl3ee81df2008-05-17 18:14:43 +00006836- Removed the macfs module. It had been deprecated since Python 2.5.
6837 This lead to the deprecation of macostools.touched() as it relied
6838 solely on macfs and was a no-op under OS X.
