78
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000079- Issue #5829: complex("1e500") no longer raises OverflowError. This

91 (1) inf and nan strings with trailing whitespace were incorrectly
92 rejected; (2) parsing of strings representing infinities and nans
93 was locale aware; and (3) the interpretation of fromhex('-nan')
94 didn't match that of float('-nan').
95
Eric Smitha985a3a2009-05-05 18:26:08 +000096- Issue #5920: For float.__format__, change the behavior with the
97 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
98 to be like 'g' but with at least one decimal point and with a
99 default precision of 12. Previously, the behavior the same but with
100 a default precision of 6. This more closely matches str(), and
101 reduces surprises when adding alignment flags to the empty
102 presentation type. This also affects the new complex.__format__ in
103 the same way.
104
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000105- Issue #5890: in subclasses of 'property' the __doc__ attribute was
106 shadowed by classtype's, even if it was None. property now
107 inserts the __doc__ into the subclass instance __dict__.
108
Antoine Pitrou653dece2009-05-04 18:32:32 +0000109- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Eric Smith9139cc62009-04-30 00:58:58 +0000113 format(complex(1, 2./3), '.5') now produces a sensible result.
114
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000115- Issue #5864: Fix empty format code formatting for floats so that it
116 never gives more than the requested number of significant digits.
117
Eric Smithcac7af62009-04-27 19:04:37 +0000118- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
119 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.

122 titlecase, but not their own uppercase.
123
Eric Smith068f0652009-04-25 21:40:15 +0000124- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with

128
Mark Dickinson95bc9802009-04-24 12:46:53 +0000129- Issue #5816: complex(repr(z)) now recovers z exactly, even when
130 z involves nans, infs or negative zeros.
131
Eric Smithaca19e62009-04-22 13:29:05 +0000132- Implement PEP 378, Format Specifier for Thousands Separator, for
133 floats, ints, and longs.
134
135- Issue #5515: 'n' formatting for ints, longs, and floats handles
136 leading zero formatting poorly.
137

142 correctly rounded.
143
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000144- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
145 some builtin types.
146
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000147- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000148 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000149
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000150- Issue #5759: float() didn't call __float__ on str subclasses.
151
Georg Brandl3c4a5462009-04-12 12:08:12 +0000152- Issue #5704: the "-3" command-line option now implies "-t".

165 the end sys.path, for compatibility with the system install of Python.
166
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000167- Issue #4688: Add a heuristic so that tuples and dicts containing only
168 untrackable objects are not tracked by the garbage collector. This can
169 reduce the size of collections and therefore the garbage collection overhead
170 on long-running programs, depending on their particular use of datatypes.
171
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000172- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
173 improve its performance. Long divisions and remainder operations
174 are now between 50% and 150% faster.
175
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000176- Issue #4258: Make it possible to use base 2**30 instead of base
177 2**15 for the internal representation of integers, for performance
178 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
179 --enable-big-digits option to configure, which overrides the
180 default. Add sys.long_info structseq to provide information about
181 the internal format.
182
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000183- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
184 result traceback.__members__ no longer exists.)
185
Mark Dickinson6b265f12009-03-18 16:07:26 +0000186- Issue #4474: PyUnicode_FromWideChar now converts characters outside
187 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
188 and sizeof(Py_UNICODE) == 2.
189
Eric Smith6f42edb2009-03-14 11:57:26 +0000190- Issue #5237: Allow auto-numbered fields in str.format(). For
191 example: '{} {}'.format(1, 2) == '1 2'.
192
Brett Cannon6c4cff02009-03-11 04:51:06 +0000193- Issue #3652: Make the 'line' argument for warnings.showwarning() a
194 requirement. Means the DeprecationWarning from Python 2.6 can go away.
195
Eric Smithe9fb6862009-02-20 14:02:36 +0000196- Issue #5247: Improve error message when unknown format codes are
197 used when using str.format() with str, unicode, long, int, and
198 float arguments.
199
Raymond Hettinger08259e82009-02-18 23:10:19 +0000200- Running Python with the -3 option now also warns about classic division
201 for ints and longs.
202
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000203- Issue #5260: Long integers now consume less memory: average
204 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
205 on a 64-bit system.
206
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000207- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
208 rotating the object pointer by 4 bits to the right.
209
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000210- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
211 it now forces its argument to double before testing for infinity.
212
Benjamin Petersone18ef192009-01-20 14:21:16 +0000213- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
214
Georg Brandl29c6a282009-04-05 20:23:13 +0000215- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000216 were suppressing all exceptions. These include list(), filter(), map(),
217 zip(), and bytearray().
218
Benjamin Peterson596d3062009-01-19 15:42:23 +0000219- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

237
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000238- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
239 collecting the oldest generation) so that allocating lots of objects without
240 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000241 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000242 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

247 an existing .py counterpart, override the co_filename attributes of all
248 code objects if the original filename is obsolete (which can happen if the
249 file has been renamed, moved, or if it is accessed through different paths).
250 Patch by Ziga Seilnacht and Jean-Paul Calderone.

Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000306 method on file objects with closefd=False. The file descriptor is still
307 kept open but the file object behaves like a closed file. The ``FileIO``
308 object also got a new readonly attribute ``closefd``.
309
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000310- Issue #4348: Some bytearray methods returned that didn't cause any change to

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000331- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
332 returned a path longer than MAX_PATH. (But It's doubtful this code path is

334
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000335- Issue #4069: When set.remove(element) is used with a set element, the element
336 is temporarily replaced with an equivalent frozenset. But the eventual

338 it correctly refers to the initial element.

359 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
360 step. This avoids problems with counting UTF-8 bytes that ignores the effect
361 of using the replace error handler in PyUnicode_DecodeUTF8().
362
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000363- Issue #3739: The unicode-internal encoder now reports the number of characters

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001495- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1496
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001497- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1498 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1499 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1500 ``printf`` function, whereas PyString_FromFormat has an independent
1501 implementation and uses "%zd" on all platforms for size_t values.
1502 This makes a difference on win64, where ``printf`` needs "%Id" to display
1503 64bit values.
1504
Benjamin Peterson97179b02008-09-09 20:55:01 +00001505- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1509 object; previously an int would be returned for small values. the __long__
1510 method is allowed to return either an int or a long, but the behaviour of
1511 float objects should not change to respect backward compatibility.
1512
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001513- Issue #3751: str.rpartition would perform a left-partition when called with
1514 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001519 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001520 was correctly parsed but parsing of subsequent arguments failed.
1521
Vinay Sajip35e3b032008-09-01 14:33:59 +00001522- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001523 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1524 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1525 when given a tuple of classes as second argument, were looking up
1526 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1527 type object.
1528
Neal Norwitz18aa3882008-08-24 05:04:52 +00001529- Fix crashes on memory allocation failure found with failmalloc.
1530
1531- Fix memory leaks found with valgrind and update suppressions file.

1598 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1599 for catch_warnings() also led to an improvement in the raising of a

1672-----------------
1673
Guido van Rossumf8402962008-08-20 15:01:50 +00001674- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1675 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1676 extensions do not automatically benefit from the class attribute
1677 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1678 to their tp_flags field if they care. This is a backwards
1679 compatibility feature; in 3.0, all types will use the cache by
1680 default.
1681
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001682- Keyword arguments can now follow starred arguments. (``f(a, *args,
1683 keyword=23)`` is now valid syntax.)
1684
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001685- ctypes function pointers that are COM methods have a boolean True
1686 value again.
1687
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001688- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1689 by denying s# to parse objects that have a releasebuffer procedure,
1690 and introducing s*.
1691
Georg Brandl1e13ea92008-08-11 09:07:59 +00001692- Issue #3537: Fix an assertion failure when an empty but presized dict
1693 object was stored in the freelist.
1694
Mark Dickinsonb6467572008-08-04 21:30:09 +00001695- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1696 ValueError consistently across platforms.
1697
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001698- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1699 (64bit Unix, for example), unichr() would truncate its argument and return
1700 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1701
Neal Norwitze7d8be82008-07-31 17:17:14 +00001702- Apply security patches from Apple.
1703
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001704- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1705 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1706
Antoine Pitrou92f82162008-07-25 22:22:08 +00001707- Issue #1819: function calls with several named parameters are now on
1708 average 35% faster (as measured by pybench).
1709
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001710- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1711 the python debugger steps into a class statement: the free variables (local

Gregory P. Smith0470bab2008-07-22 04:46:32 +00001714- Issue #2620: Overflow checking when allocating or reallocating memory
1715 was not always being done properly in some python types and extension
1716 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1717 all been updated to perform better checks and places in the code that
1718 would previously leak memory on the error path when such an allocation
1719 failed have been fixed.

1725
Benjamin Petersone977ad42008-08-20 01:42:01 +00001726- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1727 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1728
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001729- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1730 version reported by these tools does not necessarily follow the python
1731 version numbering scheme, so the module is less strict when parsing it.
1732
Nick Coghlanf70385a2008-08-18 12:42:46 +00001733- Issue #2235: Added Py3k warnings for types which will become unhashable
1734 under the stricter __hash__ inheritance rules in 3.0. Several types
1735 which did not meet the rules for hash invariants and were already
1736 unhashable in 3.0 have now been explicitly flagged as unhashable in
1737 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1738 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1739
Brett Cannon88f801d2008-08-18 00:46:22 +00001740- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1741 imported into the module but exposed as part of the module's API.
1742

1750 by using 's*' instead of 't#'.
1751
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001752- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001753 fails unicode conversion on 2nd parameter. (windows only)
1754
Facundo Batista94f243a2008-08-17 03:38:39 +00001755- Issue 2464. urllib2 now supports a malformation in the URL received
1756 in a redirect.

Facundo Batistaeb90b782008-08-16 14:44:07 +00001761- Issue #2776: fixed small issue when handling an URL with double slash
1762 after a 302 response in the case of not going through a proxy.
1763
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001764- Issue #2676: in the email package, content-type parsing was hanging on
1765 pathological input because of quadratic or exponential behaviour of a
1766 regular expression.
1767
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001768- Issue #3476: binary buffered reading through the new "io" library is now
1769 thread-safe.
1770
Brett Cannonbf3157b2008-08-14 05:00:03 +00001771- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1772 since mimetools itself is deprecated. Because modules are cached, all
1773 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1774
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001775- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001777- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1778 menu entries were not deleted.
1779
Brett Cannon83e81842008-08-09 23:30:55 +00001780- Copied the implementation of reduce() to _functools.reduce() to have a
1781 version that did not raise a DeprecationWarning under -3.
1782
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001783- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1784 a MemoryError rather than silently stop the iteration.
1785
Guido van Rossum59ce9012008-08-09 14:55:34 +00001786- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1787 to _sre.compile() will now be rejected. This should not affect anybody
1788 since the re.compile() function never generates invalid re-bytecode.
1789
Skip Montanaroa032bf42008-08-08 22:52:51 +00001790- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1791 upon first access it can be automatically initialized from the csv file if
1792 it wasn't initialized during instantiation.
1793
Brett Cannon3aa2a492008-08-06 22:28:09 +00001794- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1795 the reload() built-in has been removed.
1796
Brett Cannon7e30b672008-08-04 21:52:25 +00001797- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001798 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1806 raised an AttributeError.
1807
Benjamin Peterson01a24322008-07-28 23:35:27 +00001808- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001809 asking for a specific length. This problem only affected files opened
1810 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001811

1834
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001835- Issue #3394: zipfile.writestr sets external attributes when passed a
1836 file name rather than a ZipInfo instance, so files are extracted with
1837 mode 0600 rather than 000 under Unix.
1838
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001839- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1840 argument in python 2.5, this broke code that subclassed Popen to include its
1841 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001851- Issue #2235: the C API function PyObject_HashNotImplemented and its
1852 interaction with the tp_hash slot (added in 2.6b2) are now documented
1853
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001854- Issue #643841: The language reference now provides more detailed
1855 coverage of the lookup process for special methods. The disclaimers
1856 regarding lack of coverage of new-style classes have also been
1857 removed, since the coverage is now fairly reasonable.

1861================================
1862
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001863*Release date: 17-Jul-2008*
1864
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001865Core and Builtins
1866-----------------
1867
Georg Brandl3e483f62008-07-16 22:57:41 +00001868- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1869 its methods now allow for items objects that can be converted to
1870 an integer using operator.index().
1871
Mark Dickinson64b7e502008-07-16 09:40:03 +00001872- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1873 produced a ValueError instead of giving the correct float.
1874
Eric Smitha5fa5a22008-07-16 00:11:49 +00001875- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1876 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1877
Mark Dickinson7103aa42008-07-15 19:08:33 +00001878- Issue #3008: the float type has a new instance method 'float.hex'
1879 and a new class method 'float.fromhex' to convert floating-point
1880 numbers to and from hexadecimal strings, respectively.
1881
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001882- Issue #2235: __hash__ is once again inherited by default. To allow
1883 collections.Hashable to remain meaningful in the presence of the
1884 default hash implementation (object.__hash__), it is now possible
1885 to explicit block inheritance of hash by setting __hash__=None at
1886 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1887 level.
1888
Nick Coghlanb028f502008-07-13 14:52:36 +00001889- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1890 the parent module cannot be found while performing an absolute import.
1891 This means that an incorrectly defined __package__ attribute will
1892 now only prevent relative imports in that module rather than causing
1893 all imports from that module to fail.
1894
Nick Coghlan14ff9942008-07-08 14:21:42 +00001895- Issue #2517: Allow unicode messages in Exceptions again by correctly
1896 bypassing the instance dictionary when looking up __unicode__ on
1897 new-style classes.
1898
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001899- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1900 set to a custom object whose write() method happens to install
1901 another file in sys.stdout.
1902
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001903- Issue #3088: Corrected a race condition in classes derived from
1904 threading.local: the first member set by a thread could be saved in
1905 another thread's dictionary.
1906
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001907- Issue #3004: Minor change to slice.indices(): the start and stop
1908 arguments are now treated identically, making the behaviour easier
1909 to describe and understand. For example, slice(None, -10,
1910 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1911 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1912 10, -1).
1913
Georg Brandl278fc502008-07-19 12:46:12 +00001914- Issue #3219: Calling a function with repeated keyword arguments,
1915 f(a=2, a=23), would not cause a syntax error. This was a regression
1916 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001917
Georg Brandl278fc502008-07-19 12:46:12 +00001918- Issue #2862: Make int and float freelist management consistent with
1919 other freelists. Changes their CompactFreeList apis into
1920 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001921

1923-------
1924
Thomas Heller57adf222008-08-14 19:10:48 +00001925- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1926 api functions without holding the GIL, which could lead to a fatal
1927 error when they failed.
1928
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001929- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001937- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1938 ForkingPickler.register() to resolve conflict with ctypes.
1939
Vinay Sajip51e65192008-07-18 09:01:10 +00001940- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001941
Thomas Heller880f5292008-07-15 19:39:38 +00001942- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1943 a valid dlerror() message.
1944
Thomas Heller2bad6572008-07-15 17:19:50 +00001945- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1946 incomplete structure was created.
1947

1951
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001952- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001953
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001954- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1955 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001956 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001957 content-length. The problem had been corrected in the 2.4 branch, but never
1958 merged into trunk.
1959
Georg Brandle78fbcc2008-07-05 10:13:36 +00001960- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001973- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1974 handling is now the same as that of other special attributes like __name__).
1975
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001976- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1977 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002366 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002367
2368 This is controlled by the configure argument ``--with-universal-archs``:
2369
2370 - ``--with-universal-archs=all``: install 4-way universal
2371
2372 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2373
2374 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2375
2376 This option should be used in combination with ``--enable-universalsdk=``.
2377
2378 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 +00002428- Issue #1631171: Re-implement the 'warnings' module in C (the
2429 original Python code has been kept as backup). This will allow for
2430 using the 'warning's machinery in such places as the parser where
2431 use of pure Python code is not possible. Both the ``showarning()``
2432 and ``formatwarning()`` gain an optional 'line' argument which is
2433 not called by default for backwards-compatibility reasons. Setting
2434 ``warnings.showwarning()`` to an implementation that lacks support
2435 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002498- Issue #2550: The approach used by client/server code for obtaining
2499 ports to listen on in network-oriented tests has been refined in an
2500 effort to facilitate running multiple instances of the entire
2501 regression test suite in parallel without issue.
2502 test_support.bind_port() has been fixed such that it will always
2503 return a unique port -- which wasn't always the case with the
2504 previous implementation, especially if socket options had been set
2505 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2506 new implementation of bind_port() will actually raise an exception
2507 if it is passed an AF_INET/SOCK_STREAM socket with either the
2508 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2509 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2510 the socket it's been passed. This currently only applies to
2511 Windows. This option prevents any other sockets from binding to the
2512 host/port we've bound to, thus removing the possibility of the
2513 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2514 when a second SOCK_STREAM socket binds and accepts to a host/port
2515 that's already been bound by another socket. The optional preferred
2516 port parameter to bind_port() has been removed. Under no
2517 circumstances should tests be hard coding ports!
2518
2519 test_support.find_unused_port() has also been introduced, which will
2520 pass a temporary socket object to bind_port() in order to obtain an
2521 unused port. The temporary socket object is then closed and
2522 deleted, and the port is returned. This method should only be used
2523 for obtaining an unused port in order to pass to an external program
2524 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2525 a parameter to a server-oriented class that doesn't give you direct
2526 access to the underlying socket used.
2527
2528 Finally, test_support.HOST has been introduced, which should be used
2529 for the host argument of any relevant socket calls (i.e. bind and
2530 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002531
2532 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002533 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002534 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2535 test_asynchat and test_socket_ssl.
2536
Georg Brandl3ee81df2008-05-17 18:14:43 +00002537 It is now possible for multiple instances of the regression test
2538 suite to run in parallel without issue.

Georg Brandlad61bc82008-02-23 15:11:18 +00002810- Issue #2067: file.__exit__() now calls subclasses' close() method.
2811
2812- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002813
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002814- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002815 issue 215555 for a discussion.
2816
Eric Smitha73fbe72008-02-23 03:09:44 +00002817- Added the future_builtins module, which contains hex() and oct().
2818 These are the PEP 3127 version of these functions, designed to be
2819 compatible with the hex() and oct() builtins from Python 3.0. They
2820 differ slightly in their output formats from the existing, unchanged
2821 Python 2.6 builtins. The expected usage of the future_builtins
2822 module is:
2823 from future_builtins import hex, oct
2824
Eric Smith7ef40bf2008-02-20 23:34:22 +00002825- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2826 exponents for exponents with absolute value < 100. Follows C99
2827 standard. This is a change on Windows, which would use 3 digits.
2828 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2829 so that any alterations it does to the resulting string will be
2830 available in stringlib/formatter.h (for float.__format__).
2831
Eric Smith5a3c1352008-02-19 13:21:56 +00002832- Implemented PEP 3101, Advanced String Formatting. This adds a new
2833 builtin format(); a format() method for str and unicode; a
2834 __format__() method to object, str, unicode, int, long, float, and
2835 datetime; the class string.Formatter; and the C API
2836 PyObject_Format().
2837
Georg Brandl3ee81df2008-05-17 18:14:43 +00002838- Fixed several potential crashes, all caused by specially crafted
2839 __del__ methods exploiting objects in temporarily inconsistent
2840 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002841
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002842- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002843 prevent a possible crash: an Abstract Base Class would try to access
2844 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002845
Georg Brandl3ee81df2008-05-17 18:14:43 +00002846- Fixed repr() and str() of complex numbers with infinity or nan as
2847 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- Clear all free lists during a gc.collect() of the highest generation
2850 in order to allow pymalloc to free more arenas. Python may give back
2851 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002852
Georg Brandl3ee81df2008-05-17 18:14:43 +00002853- Issue #2045: Fix an infinite recursion triggered when printing a
2854 subclass of collections.defaultdict, if its default_factory is set
2855 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002856
Christian Heimesf75dbef2008-02-08 00:11:31 +00002857- Fixed a minor memory leak in dictobject.c. The content of the free
2858 list was not freed on interpreter shutdown.
2859
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860- Limit free list of method and builtin function objects to 256
2861 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002862
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2864 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002865 to compact the internal free lists of pre-allocted ints and floats.
2866
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2868 calls. Python expected the return type int but the fork familie
2869 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002870
Georg Brandl3ee81df2008-05-17 18:14:43 +00002871- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2872 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2881 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002882
Georg Brandl3ee81df2008-05-17 18:14:43 +00002883- Patch #1473257: generator objects gain a gi_code attribute. This is
2884 the same object as the func_code attribute of the function that
2885 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002886
Georg Brandl3ee81df2008-05-17 18:14:43 +00002887- Issue #1920: "while 0" statements were completely removed by the
2888 compiler, even in the presence of an "else" clause, which is
2889 supposed to be run when the condition is false. Now the compiler
2890 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002891
Guido van Rossumeead05f2008-01-24 18:21:02 +00002892- A few crashers fixed: weakref_in_del.py (issue #1377858);
2893 loosing_dict_ref.py (issue #1303614, test67.py);
2894 borrowed_ref_[34].py (not in tracker).
2895
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002896- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002897 suppressed while an extension is loaded by calling SetErrorMode in
2898 dynload_win.c. The error is still reported properly.
2899
Georg Brandl3ee81df2008-05-17 18:14:43 +00002900- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002901 several extension methods and modules do not work without unicode
2902 support.
2903
Georg Brandl26543b12008-01-21 18:36:51 +00002904- Issue #1882: when compiling code from a string, encoding cookies in the
2905 second line of code were not always recognized correctly.
2906
Georg Brandl14404b62008-01-19 19:27:05 +00002907- Issue #1679: "0x" was taken as a valid integer literal.
2908
Georg Brandl6caad7d2008-01-26 14:19:22 +00002909- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002910 added.
2911
Christian Heimesc94e2b52008-01-14 04:13:37 +00002912- sys.float_info / PyFloat_GetInfo: The floating point information
2913 object was converted from a dict to a specialized structseq object.
2914
Georg Brandl3ee81df2008-05-17 18:14:43 +00002915- Patch #1816: Added sys.flags structseq. It exposes the status of
2916 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002917
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918- Objects/structseq.c: Implemented new structseq representation. The
2919 patch makes structseqs (e.g. the return value of os.stat) more
2920 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002921
Georg Brandl3ee81df2008-05-17 18:14:43 +00002922- Patch #1700288: added a type attribute cache that caches method
2923 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002924
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002925- Bug #1776: __import__() no longer accepts filenames on any platform.
2926 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002927

2931 envvar and sys.dont_write_bytecode attribute. All these can be set
2932 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002933
Georg Brandl3ee81df2008-05-17 18:14:43 +00002934- Improve some exception messages when Windows fails to load an
2935 extension module. Now we get for example '%1 is not a valid Win32
2936 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002937

Christian Heimes0a8143f2007-12-18 23:22:54 +00002943- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002944 and INF. float("nan"), float("inf") and float("-inf") now work on
2945 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002946
Georg Brandl3ee81df2008-05-17 18:14:43 +00002947- Compiler now generates simpler and faster code for dictionary
2948 literals. The oparg for BUILD_MAP now indicates an estimated
2949 dictionary size. There is a new opcode, STORE_MAP, for adding
2950 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002984- Issue #1265: Fix a problem with sys.settrace, if the tracing
2985 function uses a generator expression when at the same time the
2986 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002987
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002988- sets and frozensets now have an isdisjoint() method.

2993
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994- The enumerate() builtin function is no longer bounded to sequences
2995 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2996 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Issue #1686386: Tuple's tp_repr did not take into account the
2999 possibility of having a self-referential tuple, which is possible
3000 from C code. Nor did object's tp_str consider that a type's tp_str
3001 could do something that could lead to an inifinite recursion.
3002 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3003 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003004
Georg Brandl3ee81df2008-05-17 18:14:43 +00003005- Issue #1164: It was possible to trigger deadlock when using the
3006 'print' statement to write to a file since the GIL was not released
3007 as needed. Now PyObject_Print() does the right thing along with
3008 various tp_print implementations of the built-in types and those in
3009 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003010
Georg Brandl3ee81df2008-05-17 18:14:43 +00003011- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00003018- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003019 PyObject_Call() never calling back out to Python code to trigger
3020 recursion depth updates/checks. Required the creation of a static
3021 RuntimeError instance in case normalizing an exception put the
3022 recursion check value past its limit. Fixes crashers
3023 infinite_rec_(1|2|4|5).py.

Georg Brandl2134e752007-05-21 20:34:16 +00003045- Patch #1686487: you can now pass any mapping after '**' in function
3046 calls.
3047
Collin Winter62903052007-05-18 23:11:24 +00003048- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049 "except E as target:". This is to provide forwards compatibility

Brett Cannon229cee22007-05-05 01:34:02 +00003052- Deprecate BaseException.message as per PEP 352.
3053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003055 inherited from a builtin base.
3056
Vinay Sajip8549ce32007-05-06 17:53:37 +00003057- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003058 setting a plain string, ie don't expand to single letter identifiers.
3059
Raymond Hettinger13936692007-04-11 18:40:58 +00003060- Request #1191699: Slices can now be pickled.
3061
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003062- Request #1193128: str.translate() now allows a None argument for
3063 translations that only remove characters without re-mapping the
3064 remaining characters.
3065
Georg Brandl5cb76c12007-03-21 09:00:39 +00003066- Patch #1682205: a TypeError while unpacking an iterable is no longer

3070
Guido van Rossum143b5642007-03-23 04:58:42 +00003071- Bug #1683368: The object.__init__() and object.__new__() methods are
3072 now stricter in rejecting excess arguments. The only time when
3073 either allows excess arguments is when it is not overridden and the
3074 other one is. For backwards compatibility, when both are
3075 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003076 warning later). Also, type.__init__() insists on the same signature
3077 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003078
Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3080 object to complex using its __complex__() method before falling back
3081 to the __float__() method. Therefore, the functions in the cmath
3082 module now can operate on objects that define a __complex__()
3083 method.

3100
Georg Brandl7b9c5552007-03-12 14:30:05 +00003101- Bug #1678647: write a newline after printing an exception in any
3102 case, even when converting the value to a string failed.
3103
Georg Brandl871f1bc2007-03-12 13:17:36 +00003104- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003105 its argument, if it exists. If not, it will work like before. This
3106 allows customizing the output of dir() in the presence of a
3107 __getattr__().

3110 self-recursive reload() calls (as reported by bug #742342).

3116 parthensized forms. This means complex(repr(x)) now works instead of
3117 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003118
Georg Brandlaa2321b2007-03-07 00:40:28 +00003119- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003120 makes the filenames the warning module prints much more sensible
3121 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003122

Georg Brandl0fca97a2007-03-05 22:28:08 +00003134- Patch #1674228: when assigning a slice (old-style), check for the
3135 sq_ass_slice instead of the sq_slice slot.
3136
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- When printing an unraisable error, don't print exceptions. before
3138 the name. This duplicates the behavior whening normally printing
3139 exceptions.

3148 created a weakref on itself during a __del__ call for new-style
3149 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00003189- Bug #1545497: when given an explicit base, int() did ignore NULs
3190 embedded in the string to convert.
3191
Georg Brandl846f73a2006-10-08 07:11:54 +00003192- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003240 generator expressions (x for x, in ... ) works again. Fixing this
3241 problem required changing the .pyc magic number. This means that
3242 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004049- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4050 with RFC 3207 and forgets any knowledge obtained from the server not
4051 obtained from the TLS negotiation itself. Patch contributed by Bill
4052 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004053
Georg Brandl3ee81df2008-05-17 18:14:43 +00004054- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004055 that the SMTP.starttls() caller no longer needs to call ehlo()
4056 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004057 does not claim to support starttls. Adds the
4058 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4059 Fenner.

4139 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4140 silently miscode subclasses of those types. Now, it raises a
4141 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004142

Georg Brandl3ee81df2008-05-17 18:14:43 +00004157 time so that opening a database previously created with the DB_DUP
4158 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4159 opens. Specifically: dictionary assignment to a DB object will
4160 replace all values for a given key when the database allows
4161 duplicate values. DB users should use DB.put(k, v) when they want
4162 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004163

4169 characters with ASCII value less than 32. Also, it correctly quotes
4170 dots only if they occur on a single line, as opposed to the previous
4171 behavior of quoting dots if they are the second character of any
4172 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004173

Georg Brandl3ee81df2008-05-17 18:14:43 +00004578- Removed the macfs module. It had been deprecated since Python 2.5.
4579 This lead to the deprecation of macostools.touched() as it relied
