125 statement and correctly lookup the __enter__ and __exit__ special methods.
126
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000127- Issue #5829: complex("1e500") no longer raises OverflowError. This

140 rejected; (2) parsing of strings representing infinities and nans
141 was locale aware; and (3) the interpretation of fromhex('-nan')
142 didn't match that of float('-nan').
143
Eric Smitha985a3a2009-05-05 18:26:08 +0000144- Issue #5920: For float.__format__, change the behavior with the
145 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
146 to be like 'g' but with at least one decimal point and with a
147 default precision of 12. Previously, the behavior the same but with
148 a default precision of 6. This more closely matches str(), and
149 reduces surprises when adding alignment flags to the empty
150 presentation type. This also affects the new complex.__format__ in
151 the same way.
152
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000153- Issue #5890: in subclasses of 'property' the __doc__ attribute was

162
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000163- Issue #5864: Fix empty format code formatting for floats so that it
164 never gives more than the requested number of significant digits.
165

176
Mark Dickinson95bc9802009-04-24 12:46:53 +0000177- Issue #5816: complex(repr(z)) now recovers z exactly, even when
178 z involves nans, infs or negative zeros.
179
Eric Smithaca19e62009-04-22 13:29:05 +0000180- Implement PEP 378, Format Specifier for Thousands Separator, for
181 floats, ints, and longs.
182
183- Issue #5515: 'n' formatting for ints, longs, and floats handles
184 leading zero formatting poorly.
185
186- Issue #5772: For float.__format__, don't add a trailing ".0" if
187 we're using no type code and we have an exponent.
188

193 some builtin types.
194
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000195- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000196 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000197
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000198- Issue #5759: float() didn't call __float__ on str subclasses.

216 untrackable objects are not tracked by the garbage collector. This can
217 reduce the size of collections and therefore the garbage collection overhead
218 on long-running programs, depending on their particular use of datatypes.
219
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000220- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
221 improve its performance. Long divisions and remainder operations
222 are now between 50% and 150% faster.
223
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000224- Issue #4258: Make it possible to use base 2**30 instead of base
225 2**15 for the internal representation of integers, for performance
226 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
227 --enable-big-digits option to configure, which overrides the
228 default. Add sys.long_info structseq to provide information about
229 the internal format.
230

232 result traceback.__members__ no longer exists.)
233
Mark Dickinson6b265f12009-03-18 16:07:26 +0000234- Issue #4474: PyUnicode_FromWideChar now converts characters outside
235 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

237
Eric Smith6f42edb2009-03-14 11:57:26 +0000238- Issue #5237: Allow auto-numbered fields in str.format(). For
239 example: '{} {}'.format(1, 2) == '1 2'.
240
Brett Cannon6c4cff02009-03-11 04:51:06 +0000241- Issue #3652: Make the 'line' argument for warnings.showwarning() a
242 requirement. Means the DeprecationWarning from Python 2.6 can go away.
243

246 float arguments.
247

249 for ints and longs.
250
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000251- Issue #5260: Long integers now consume less memory: average
252 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
253 on a 64-bit system.
254
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000255- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
256 rotating the object pointer by 4 bits to the right.

260
Benjamin Petersone18ef192009-01-20 14:21:16 +0000261- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
262
Georg Brandl29c6a282009-04-05 20:23:13 +0000263- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000264 were suppressing all exceptions. These include list(), filter(), map(),
265 zip(), and bytearray().
266
Benjamin Peterson596d3062009-01-19 15:42:23 +0000267- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

304
Antoine Pitrouaa687902009-01-01 14:11:22 +0000305- Issue #3680: Reference cycles created through a dict, set or deque iterator
306 did not get collected.
307
Nick Coghlan180e4002008-12-30 01:18:48 +0000308- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
309 where the tp_hash and tp_dict slots are both NULL.
310
Benjamin Peterson7af65562008-12-29 17:56:58 +0000311- Issue #4764: With io.open, IOError.filename is set when trying to open a
312 directory on POSIX systems.
313
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000314- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
315 systems.
316
Georg Brandl6425a2f2008-12-28 11:54:53 +0000317- Issue #4759: None is now allowed as the first argument of
318 bytearray.translate(). It was always allowed for bytes.translate().
319
Skip Montanarof205c132008-12-23 03:30:15 +0000320- Added test case to ensure attempts to read from a file opened for writing
321 fail.
322
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000323- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
324 print elapsed times, not only when some objects are uncollectable /
325 unreachable. Original patch by Neil Schemenauer.

333 context manager returns a value that cannot be converted to a bool.
334
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000335- Issue #4597: Fixed several opcodes that weren't always propagating

337
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000338- Issue #4445: Replace "sizeof(PyStringObject)" with
339 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
340 str instances. On a typical machine this saves 3 bytes of memory
341 (on average) per string allocation.
342
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000343- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

352
Vinay Sajip213faca2008-12-03 23:22:58 +0000353- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000354 method on file objects with closefd=False. The file descriptor is still
355 kept open but the file object behaves like a closed file. The ``FileIO``
356 object also got a new readonly attribute ``closefd``.
357
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000358- Issue #4348: Some bytearray methods returned that didn't cause any change to
359 the bytearray, returned the same bytearray instead of a copy.
360

366
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000367- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
368 exec statement.
369
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000370- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
371 method does not return iterators for the 4th and 5th items.
372
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000373- Issue #4209: Enabling unicode_literals and the print_function in the same
374 __future__ import didn't work.
375
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000376- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000377 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000378
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000379- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
380 returned a path longer than MAX_PATH. (But It's doubtful this code path is
381 really executed because I cannot move to such directory on win2k)
382
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000383- Issue #4069: When set.remove(element) is used with a set element, the element
384 is temporarily replaced with an equivalent frozenset. But the eventual
385 KeyError would always report the empty frozenset([]) as the missing key. Now
386 it correctly refers to the initial element.
387
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000388- Issue #4509: Various issues surrounding resize of bytearray objects to
389 which there are buffer exports.
390

398 short file names.
399
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000400- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
401 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000402
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000403- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
404 returned them on 64bit platforms.
405
Walter Dörwalded960ac2009-05-03 22:36:33 +0000406- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
407 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
408 step. This avoids problems with counting UTF-8 bytes that ignores the effect
409 of using the replace error handler in PyUnicode_DecodeUTF8().
410
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000411- Issue #3739: The unicode-internal encoder now reports the number of characters
412 consumed like any other encoder (instead of the number of bytes).

1434 Unicode category 'Nd' (Number, Decimal Digit). Previously it also
1435 matched characters with category 'No'.

Mark Dickinson5fd3af22009-07-07 15:08:28 +00001437- Issue #1523: Remove deprecated overflow wrapping for struct.pack
1438 with an integer format code ('bBhHiIlLqQ'). Packing an out-of-range
1439 integer now consistently raises struct.error.
1440
Mark Dickinson463dc4b2009-07-05 10:01:24 +00001441- Issues #1530559, #1741130: Fix various struct.pack inconsistencies

1453 TypeError used to be raised (with a confusing error message) for
1454 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

1503 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1504 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1505 skip the tests if DISPLAY is defined but can't be used.

Nick Coghlan5533ff62009-04-22 15:26:04 +00001510- Issue #5354: New test support function import_fresh_module() makes
1511 it easy to import both normal and optimised versions of modules.
1512 test_heapq and test_warnings have been adjusted to use it, tests for
1513 other modules with both C and Python implementations in the stdlib
1514 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00001522- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001523 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001524 from test support, which does the conversion.

1621
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001622- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1623 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1624 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1625 ``printf`` function, whereas PyString_FromFormat has an independent
1626 implementation and uses "%zd" on all platforms for size_t values.
1627 This makes a difference on win64, where ``printf`` needs "%Id" to display
1628 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001630- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitrou0668c622008-08-26 22:42:08 +00001648 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1649 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1650 when given a tuple of classes as second argument, were looking up
1651 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1652 type object.

1723 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1724 for catch_warnings() also led to an improvement in the raising of a
1725 DeprecationWarning related to warnings.warn_explicit().

1749
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001750- Issue #2975: When compiling several extension modules with Visual Studio 2008
1751 from the same python interpreter, some environment variables would grow
1752 without limit.
1753
Benjamin Peterson37346b22008-08-23 20:27:43 +00001754- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001791What's New in Python 2.6 beta 3?
1792================================
1793
Barry Warsaw07a4a382008-08-21 01:15:08 +00001794*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001795
1796Core and Builtins
1797-----------------
1798
Guido van Rossumf8402962008-08-20 15:01:50 +00001799- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1800 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1801 extensions do not automatically benefit from the class attribute
1802 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1803 to their tp_flags field if they care. This is a backwards
1804 compatibility feature; in 3.0, all types will use the cache by
1805 default.
1806
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001807- Keyword arguments can now follow starred arguments. (``f(a, *args,
1808 keyword=23)`` is now valid syntax.)
1809
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001810- ctypes function pointers that are COM methods have a boolean True
1811 value again.
1812
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001813- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1814 by denying s# to parse objects that have a releasebuffer procedure,
1815 and introducing s*.
1816
Georg Brandl1e13ea92008-08-11 09:07:59 +00001817- Issue #3537: Fix an assertion failure when an empty but presized dict
1818 object was stored in the freelist.
1819
Mark Dickinsonb6467572008-08-04 21:30:09 +00001820- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1821 ValueError consistently across platforms.
1822
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001823- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1824 (64bit Unix, for example), unichr() would truncate its argument and return
1825 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1826
Neal Norwitze7d8be82008-07-31 17:17:14 +00001827- Apply security patches from Apple.
1828
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001829- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1830 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1831
Antoine Pitrou92f82162008-07-25 22:22:08 +00001832- Issue #1819: function calls with several named parameters are now on
1833 average 35% faster (as measured by pybench).
1834
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001835- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1836 the python debugger steps into a class statement: the free variables (local
1837 variables defined in an outer scope) would be deleted from the outer scope.
1838
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001839- Issue #2620: Overflow checking when allocating or reallocating memory
1840 was not always being done properly in some python types and extension
1841 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1842 all been updated to perform better checks and places in the code that
1843 would previously leak memory on the error path when such an allocation
1844 failed have been fixed.
1845

1847-------
1848

1850
Benjamin Petersone977ad42008-08-20 01:42:01 +00001851- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1852 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1853
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001854- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1855 version reported by these tools does not necessarily follow the python
1856 version numbering scheme, so the module is less strict when parsing it.
1857
Nick Coghlanf70385a2008-08-18 12:42:46 +00001858- Issue #2235: Added Py3k warnings for types which will become unhashable
1859 under the stricter __hash__ inheritance rules in 3.0. Several types
1860 which did not meet the rules for hash invariants and were already
1861 unhashable in 3.0 have now been explicitly flagged as unhashable in
1862 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1863 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1864
Brett Cannon88f801d2008-08-18 00:46:22 +00001865- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1873
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001874- Issue #3575: Incremental decoder's decode function now takes bytearray
1875 by using 's*' instead of 't#'.
1876
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001877- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001878 fails unicode conversion on 2nd parameter. (windows only)
1879
Facundo Batista94f243a2008-08-17 03:38:39 +00001880- Issue 2464. urllib2 now supports a malformation in the URL received
1881 in a redirect.
1882
Brett Cannonabe423e2008-08-16 21:47:07 +00001883- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001884 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001885
Facundo Batistaeb90b782008-08-16 14:44:07 +00001886- Issue #2776: fixed small issue when handling an URL with double slash
1887 after a 302 response in the case of not going through a proxy.
1888
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001889- Issue #2676: in the email package, content-type parsing was hanging on
1890 pathological input because of quadratic or exponential behaviour of a
1891 regular expression.
1892
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001893- Issue #3476: binary buffered reading through the new "io" library is now
1894 thread-safe.
1895
Brett Cannonbf3157b2008-08-14 05:00:03 +00001896- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1897 since mimetools itself is deprecated. Because modules are cached, all
1898 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1899
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001900- Issue #3134: shutil referenced undefined WindowsError symbol.
1901
Robert Schuppenies14646332008-08-10 11:01:53 +00001902- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1903 menu entries were not deleted.
1904
Brett Cannon83e81842008-08-09 23:30:55 +00001905- Copied the implementation of reduce() to _functools.reduce() to have a
1906 version that did not raise a DeprecationWarning under -3.
1907
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001908- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1909 a MemoryError rather than silently stop the iteration.
1910
Guido van Rossum59ce9012008-08-09 14:55:34 +00001911- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1912 to _sre.compile() will now be rejected. This should not affect anybody
1913 since the re.compile() function never generates invalid re-bytecode.
1914
Skip Montanaroa032bf42008-08-08 22:52:51 +00001915- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00001934 asking for a specific length. This problem only affected files opened
1935 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001936

1961 file name rather than a ZipInfo instance, so files are extracted with
1962 mode 0600 rather than 000 under Unix.
1963
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001964- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001990Core and Builtins
1991-----------------
1992
Georg Brandl3e483f62008-07-16 22:57:41 +00001993- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1994 its methods now allow for items objects that can be converted to
1995 an integer using operator.index().
1996
Mark Dickinson64b7e502008-07-16 09:40:03 +00001997- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1998 produced a ValueError instead of giving the correct float.
1999
Eric Smitha5fa5a22008-07-16 00:11:49 +00002000- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2001 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2002
Mark Dickinson7103aa42008-07-15 19:08:33 +00002003- Issue #3008: the float type has a new instance method 'float.hex'
2004 and a new class method 'float.fromhex' to convert floating-point
2005 numbers to and from hexadecimal strings, respectively.
2006
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002007- Issue #2235: __hash__ is once again inherited by default. To allow
2008 collections.Hashable to remain meaningful in the presence of the
2009 default hash implementation (object.__hash__), it is now possible
2010 to explicit block inheritance of hash by setting __hash__=None at
2011 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2012 level.
2013
Nick Coghlanb028f502008-07-13 14:52:36 +00002014- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2015 the parent module cannot be found while performing an absolute import.
2016 This means that an incorrectly defined __package__ attribute will
2017 now only prevent relative imports in that module rather than causing
2018 all imports from that module to fail.
2019
Nick Coghlan14ff9942008-07-08 14:21:42 +00002020- Issue #2517: Allow unicode messages in Exceptions again by correctly
2021 bypassing the instance dictionary when looking up __unicode__ on
2022 new-style classes.
2023
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002024- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2025 set to a custom object whose write() method happens to install
2026 another file in sys.stdout.
2027
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002028- Issue #3088: Corrected a race condition in classes derived from
2029 threading.local: the first member set by a thread could be saved in
2030 another thread's dictionary.
2031
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002032- Issue #3004: Minor change to slice.indices(): the start and stop
2033 arguments are now treated identically, making the behaviour easier
2034 to describe and understand. For example, slice(None, -10,
2035 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2036 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2037 10, -1).
2038
Georg Brandl278fc502008-07-19 12:46:12 +00002039- Issue #3219: Calling a function with repeated keyword arguments,
2040 f(a=2, a=23), would not cause a syntax error. This was a regression
2041 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002042
Georg Brandl278fc502008-07-19 12:46:12 +00002043- Issue #2862: Make int and float freelist management consistent with
2044 other freelists. Changes their CompactFreeList apis into
2045 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002046

2048-------
2049
Thomas Heller57adf222008-08-14 19:10:48 +00002050- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2051 api functions without holding the GIL, which could lead to a fatal
2052 error when they failed.
2053
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002054- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002062- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2063 ForkingPickler.register() to resolve conflict with ctypes.
2064
Vinay Sajip51e65192008-07-18 09:01:10 +00002065- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002066
Thomas Heller880f5292008-07-15 19:39:38 +00002067- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2068 a valid dlerror() message.
2069
Thomas Heller2bad6572008-07-15 17:19:50 +00002070- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2071 incomplete structure was created.

2076
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002077- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002078
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002079- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2080 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002081 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002082 content-length. The problem had been corrected in the 2.4 branch, but never
2083 merged into trunk.
2084
Georg Brandle78fbcc2008-07-05 10:13:36 +00002085- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00002093 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002094

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002096 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002097
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002098- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2099 handling is now the same as that of other special attributes like __name__).
2100
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002101- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002553- Issue #1631171: Re-implement the 'warnings' module in C (the
2554 original Python code has been kept as backup). This will allow for
2555 using the 'warning's machinery in such places as the parser where
2556 use of pure Python code is not possible. Both the ``showarning()``
2557 and ``formatwarning()`` gain an optional 'line' argument which is
2558 not called by default for backwards-compatibility reasons. Setting
2559 ``warnings.showwarning()`` to an implementation that lacks support
2560 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002623- Issue #2550: The approach used by client/server code for obtaining
2624 ports to listen on in network-oriented tests has been refined in an
2625 effort to facilitate running multiple instances of the entire
2626 regression test suite in parallel without issue.
2627 test_support.bind_port() has been fixed such that it will always
2628 return a unique port -- which wasn't always the case with the
2629 previous implementation, especially if socket options had been set
2630 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2631 new implementation of bind_port() will actually raise an exception
2632 if it is passed an AF_INET/SOCK_STREAM socket with either the
2633 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2634 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2635 the socket it's been passed. This currently only applies to
2636 Windows. This option prevents any other sockets from binding to the
2637 host/port we've bound to, thus removing the possibility of the
2638 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2639 when a second SOCK_STREAM socket binds and accepts to a host/port
2640 that's already been bound by another socket. The optional preferred
2641 port parameter to bind_port() has been removed. Under no
2642 circumstances should tests be hard coding ports!
2643
2644 test_support.find_unused_port() has also been introduced, which will
2645 pass a temporary socket object to bind_port() in order to obtain an
2646 unused port. The temporary socket object is then closed and
2647 deleted, and the port is returned. This method should only be used
2648 for obtaining an unused port in order to pass to an external program
2649 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2650 a parameter to a server-oriented class that doesn't give you direct
2651 access to the underlying socket used.
2652
2653 Finally, test_support.HOST has been introduced, which should be used
2654 for the host argument of any relevant socket calls (i.e. bind and
2655 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002656
2657 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002658 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002659 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2660 test_asynchat and test_socket_ssl.
2661
Georg Brandl3ee81df2008-05-17 18:14:43 +00002662 It is now possible for multiple instances of the regression test
2663 suite to run in parallel without issue.

2819 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002820 platform.machine() and platform.processor() will report this
2821 information as well.

2930-----------------
2931
Fred Drakea8ee94b2008-03-01 02:45:07 +00002932- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002933 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002934
Georg Brandlad61bc82008-02-23 15:11:18 +00002935- Issue #2067: file.__exit__() now calls subclasses' close() method.
2936
2937- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002938
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002939- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002940 issue 215555 for a discussion.
2941
Eric Smitha73fbe72008-02-23 03:09:44 +00002942- Added the future_builtins module, which contains hex() and oct().
2943 These are the PEP 3127 version of these functions, designed to be
2944 compatible with the hex() and oct() builtins from Python 3.0. They
2945 differ slightly in their output formats from the existing, unchanged
2946 Python 2.6 builtins. The expected usage of the future_builtins
2947 module is:
2948 from future_builtins import hex, oct
2949
Eric Smith7ef40bf2008-02-20 23:34:22 +00002950- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2951 exponents for exponents with absolute value < 100. Follows C99
2952 standard. This is a change on Windows, which would use 3 digits.
2953 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2954 so that any alterations it does to the resulting string will be
2955 available in stringlib/formatter.h (for float.__format__).
2956
Eric Smith5a3c1352008-02-19 13:21:56 +00002957- Implemented PEP 3101, Advanced String Formatting. This adds a new
2958 builtin format(); a format() method for str and unicode; a
2959 __format__() method to object, str, unicode, int, long, float, and
2960 datetime; the class string.Formatter; and the C API
2961 PyObject_Format().
2962
Georg Brandl3ee81df2008-05-17 18:14:43 +00002963- Fixed several potential crashes, all caused by specially crafted
2964 __del__ methods exploiting objects in temporarily inconsistent
2965 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002966
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002967- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968 prevent a possible crash: an Abstract Base Class would try to access
2969 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002970

Georg Brandl3ee81df2008-05-17 18:14:43 +00002974- Clear all free lists during a gc.collect() of the highest generation
2975 in order to allow pymalloc to free more arenas. Python may give back
2976 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002977
Georg Brandl3ee81df2008-05-17 18:14:43 +00002978- Issue #2045: Fix an infinite recursion triggered when printing a
2979 subclass of collections.defaultdict, if its default_factory is set
2980 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002981
Christian Heimesf75dbef2008-02-08 00:11:31 +00002982- Fixed a minor memory leak in dictobject.c. The content of the free
2983 list was not freed on interpreter shutdown.
2984
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985- Limit free list of method and builtin function objects to 256
2986 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2989 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002990 to compact the internal free lists of pre-allocted ints and floats.
2991
Georg Brandl3ee81df2008-05-17 18:14:43 +00002992- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2993 calls. Python expected the return type int but the fork familie
2994 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002995
Georg Brandl3ee81df2008-05-17 18:14:43 +00002996- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2997 appear in the same code unit.

3006 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003007
Georg Brandl3ee81df2008-05-17 18:14:43 +00003008- Patch #1473257: generator objects gain a gi_code attribute. This is
3009 the same object as the func_code attribute of the function that
3010 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003011
Georg Brandl3ee81df2008-05-17 18:14:43 +00003012- Issue #1920: "while 0" statements were completely removed by the
3013 compiler, even in the presence of an "else" clause, which is
3014 supposed to be run when the condition is false. Now the compiler
3015 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003016
Guido van Rossumeead05f2008-01-24 18:21:02 +00003017- A few crashers fixed: weakref_in_del.py (issue #1377858);
3018 loosing_dict_ref.py (issue #1303614, test67.py);
3019 borrowed_ref_[34].py (not in tracker).
3020
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003021- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003022 suppressed while an extension is loaded by calling SetErrorMode in

3024
Georg Brandl3ee81df2008-05-17 18:14:43 +00003025- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003026 several extension methods and modules do not work without unicode
3027 support.
3028
Georg Brandl26543b12008-01-21 18:36:51 +00003029- Issue #1882: when compiling code from a string, encoding cookies in the
3030 second line of code were not always recognized correctly.
3031
Georg Brandl14404b62008-01-19 19:27:05 +00003032- Issue #1679: "0x" was taken as a valid integer literal.
3033
Georg Brandl6caad7d2008-01-26 14:19:22 +00003034- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003035 added.
3036
Christian Heimesc94e2b52008-01-14 04:13:37 +00003037- sys.float_info / PyFloat_GetInfo: The floating point information
3038 object was converted from a dict to a specialized structseq object.
3039
Georg Brandl3ee81df2008-05-17 18:14:43 +00003040- Patch #1816: Added sys.flags structseq. It exposes the status of
3041 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003042
Georg Brandl3ee81df2008-05-17 18:14:43 +00003043- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Improve some exception messages when Windows fails to load an
3060 extension module. Now we get for example '%1 is not a valid Win32
3061 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003062

Christian Heimes0a8143f2007-12-18 23:22:54 +00003068- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003069 and INF. float("nan"), float("inf") and float("-inf") now work on
3070 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003071
Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Compiler now generates simpler and faster code for dictionary
3073 literals. The oparg for BUILD_MAP now indicates an estimated
3074 dictionary size. There is a new opcode, STORE_MAP, for adding
3075 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003104- Patch #1739468: Directories and zipfiles containing a __main__.py
3105 file can now be directly executed by passing their name to the
3106 interpreter. The directory/zipfile is automatically inserted as the
3107 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003108
Georg Brandl3ee81df2008-05-17 18:14:43 +00003109- Issue #1265: Fix a problem with sys.settrace, if the tracing
3110 function uses a generator expression when at the same time the
3111 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003112
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003113- sets and frozensets now have an isdisjoint() method.

3118
Georg Brandl3ee81df2008-05-17 18:14:43 +00003119- The enumerate() builtin function is no longer bounded to sequences
3120 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3121 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003122
Georg Brandl3ee81df2008-05-17 18:14:43 +00003123- Issue #1686386: Tuple's tp_repr did not take into account the
3124 possibility of having a self-referential tuple, which is possible
3125 from C code. Nor did object's tp_str consider that a type's tp_str
3126 could do something that could lead to an inifinite recursion.
3127 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3128 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003129
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- Issue #1164: It was possible to trigger deadlock when using the
3131 'print' statement to write to a file since the GIL was not released
3132 as needed. Now PyObject_Print() does the right thing along with
3133 various tp_print implementations of the built-in types and those in
3134 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Issue #1147: Exceptions were directly allowing string exceptions in
3137 their throw() method even though string exceptions no longer
3138 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003139
Georg Brandl3ee81df2008-05-17 18:14:43 +00003140- Issue #1096: Prevent a segfault from getting the repr of a very
3141 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003142
Brett Cannon1e534b52007-09-07 04:18:30 +00003143- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144 PyObject_Call() never calling back out to Python code to trigger
3145 recursion depth updates/checks. Required the creation of a static
3146 RuntimeError instance in case normalizing an exception put the
3147 recursion check value past its limit. Fixes crashers
3148 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003149
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003163- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164 __*__ attributes. (Some already existed, e.g., __doc__ and
3165 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003166
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003167- Add -3 option to the interpreter to warn about features that are
3168 deprecated and will be changed/removed in Python 3.0.
3169
Georg Brandl2134e752007-05-21 20:34:16 +00003170- Patch #1686487: you can now pass any mapping after '**' in function
3171 calls.
3172
Collin Winter62903052007-05-18 23:11:24 +00003173- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174 "except E as target:". This is to provide forwards compatibility
3175 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003176
Brett Cannon229cee22007-05-05 01:34:02 +00003177- Deprecate BaseException.message as per PEP 352.
3178
Georg Brandl3ee81df2008-05-17 18:14:43 +00003179- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003180 inherited from a builtin base.
3181
Vinay Sajip8549ce32007-05-06 17:53:37 +00003182- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003183 setting a plain string, ie don't expand to single letter identifiers.
3184
Raymond Hettinger13936692007-04-11 18:40:58 +00003185- Request #1191699: Slices can now be pickled.
3186
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003187- Request #1193128: str.translate() now allows a None argument for
3188 translations that only remove characters without re-mapping the
3189 remaining characters.
3190
Georg Brandl5cb76c12007-03-21 09:00:39 +00003191- Patch #1682205: a TypeError while unpacking an iterable is no longer
3192 masked by a generic one with the message "unpack non-sequence".
3193
Neal Norwitzaa754b72007-03-21 06:39:48 +00003194- Remove unused file Python/fmod.c.
3195
Guido van Rossum143b5642007-03-23 04:58:42 +00003196- Bug #1683368: The object.__init__() and object.__new__() methods are
3197 now stricter in rejecting excess arguments. The only time when
3198 either allows excess arguments is when it is not overridden and the
3199 other one is. For backwards compatibility, when both are
3200 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003201 warning later). Also, type.__init__() insists on the same signature
3202 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003203
Georg Brandl3ee81df2008-05-17 18:14:43 +00003204- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3205 object to complex using its __complex__() method before falling back
3206 to the __float__() method. Therefore, the functions in the cmath
3207 module now can operate on objects that define a __complex__()
3208 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003209
Georg Brandl3ee81df2008-05-17 18:14:43 +00003210- Patch #1623563: allow __class__ assignment for classes with
3211 __slots__. The old and the new class are still required to have the
3212 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003213
Georg Brandl3ee81df2008-05-17 18:14:43 +00003214- Patch #1642547: Fix an error/crash when encountering syntax errors

3218 ``object.__reduce_ex__()`` is called with an object that is faking
3219 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003220
Georg Brandl3ee81df2008-05-17 18:14:43 +00003221- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003224- Patch #1444529: the builtin compile() now accepts keyword arguments.
3225
Georg Brandl7b9c5552007-03-12 14:30:05 +00003226- Bug #1678647: write a newline after printing an exception in any
3227 case, even when converting the value to a string failed.
3228
Georg Brandl871f1bc2007-03-12 13:17:36 +00003229- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003230 its argument, if it exists. If not, it will work like before. This
3231 allows customizing the output of dir() in the presence of a
3232 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003233
Collin Winter276887b2007-03-12 16:11:39 +00003234- Patch #922167: Python no longer segfaults when faced with infinitely
3235 self-recursive reload() calls (as reported by bug #742342).
3236
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237- Patch #1675981: remove unreachable code from ``type.__new__()``
3238 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003240- Patch #1491866: change the complex() constructor to allow
3241 parthensized forms. This means complex(repr(x)) now works instead of
3242 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003243
Georg Brandlaa2321b2007-03-07 00:40:28 +00003244- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245 makes the filenames the warning module prints much more sensible
3246 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003247
Georg Brandl49aafc92007-03-07 00:34:46 +00003248- Variant of patch #697613: don't exit the interpreter on a SystemExit
3249 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250 variable is given, but break into the interactive interpreter just
3251 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00003258
Georg Brandl0fca97a2007-03-05 22:28:08 +00003259- Patch #1674228: when assigning a slice (old-style), check for the
3260 sq_ass_slice instead of the sq_slice slot.
3261
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262- When printing an unraisable error, don't print exceptions. before
3263 the name. This duplicates the behavior whening normally printing
3264 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003265
Georg Brandl3ee81df2008-05-17 18:14:43 +00003266- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003797 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00003799

Georg Brandl3ee81df2008-05-17 18:14:43 +00003815- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl92a6bae2007-03-13 17:43:32 +00003831- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832 are set for invalid interpolation sequences that would lead to
3833 errors on reading back those values.

3889 TestCase and TestSuite subclasses (not instances) are no longer
3890 accepted in TestSuite.addTest(). This should cause no
3891 incompatibility since it never made sense with ordinary subclasses
3892 -- the failure just occurred later, with a more cumbersome
3893 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004180 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004281- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004282 time so that opening a database previously created with the DB_DUP
4283 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4284 opens. Specifically: dictionary assignment to a DB object will
4285 replace all values for a given key when the database allows
4286 duplicate values. DB users should use DB.put(k, v) when they want
4287 to store duplicates; not DB[k] = v.

Christian Heimes5b970ad2008-02-06 13:33:44 +00004626
Georg Brandl3ee81df2008-05-17 18:14:43 +00004627- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4628 to ``PyTuple_SetItem``, it can be used to populate a brand new
4629 frozenset; but it does not steal a reference to the added item.

4641
Georg Brandl3ee81df2008-05-17 18:14:43 +00004642- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4643 of w# format code incorrectly truncated the length to an int, even
4644 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4645 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004646
Georg Brandl3ee81df2008-05-17 18:14:43 +00004647- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4669 outside of pystate.c and should not be necessary.
4670
Georg Brandl3ee81df2008-05-17 18:14:43 +00004671- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4672 absolute imports. In earlier versions they might have used relative
4673 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004674
Georg Brandl3ee81df2008-05-17 18:14:43 +00004675- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4676 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004677
Georg Brandl3ee81df2008-05-17 18:14:43 +00004678- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
