91
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000092- Issue #5829: complex("1e500") no longer raises OverflowError. This

104 (1) inf and nan strings with trailing whitespace were incorrectly
105 rejected; (2) parsing of strings representing infinities and nans
106 was locale aware; and (3) the interpretation of fromhex('-nan')
107 didn't match that of float('-nan').
108
Eric Smitha985a3a2009-05-05 18:26:08 +0000109- Issue #5920: For float.__format__, change the behavior with the
110 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
111 to be like 'g' but with at least one decimal point and with a
112 default precision of 12. Previously, the behavior the same but with
113 a default precision of 6. This more closely matches str(), and
114 reduces surprises when adding alignment flags to the empty
115 presentation type. This also affects the new complex.__format__ in
116 the same way.
117
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000118- Issue #5890: in subclasses of 'property' the __doc__ attribute was

143 z involves nans, infs or negative zeros.
144
Eric Smithaca19e62009-04-22 13:29:05 +0000145- Implement PEP 378, Format Specifier for Thousands Separator, for
146 floats, ints, and longs.
147
148- Issue #5515: 'n' formatting for ints, longs, and floats handles
149 leading zero formatting poorly.

159
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000160- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000161 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000162
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000163- Issue #5759: float() didn't call __float__ on str subclasses.

179
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000180- Issue #4688: Add a heuristic so that tuples and dicts containing only
181 untrackable objects are not tracked by the garbage collector. This can
182 reduce the size of collections and therefore the garbage collection overhead
183 on long-running programs, depending on their particular use of datatypes.
184
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000185- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

188
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000189- Issue #4258: Make it possible to use base 2**30 instead of base
190 2**15 for the internal representation of integers, for performance
191 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
192 --enable-big-digits option to configure, which overrides the
193 default. Add sys.long_info structseq to provide information about
194 the internal format.
195
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000196- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
197 result traceback.__members__ no longer exists.)
198
Mark Dickinson6b265f12009-03-18 16:07:26 +0000199- Issue #4474: PyUnicode_FromWideChar now converts characters outside

202
Eric Smith6f42edb2009-03-14 11:57:26 +0000203- Issue #5237: Allow auto-numbered fields in str.format(). For
204 example: '{} {}'.format(1, 2) == '1 2'.
205
Brett Cannon6c4cff02009-03-11 04:51:06 +0000206- Issue #3652: Make the 'line' argument for warnings.showwarning() a
207 requirement. Means the DeprecationWarning from Python 2.6 can go away.
208
Eric Smithe9fb6862009-02-20 14:02:36 +0000209- Issue #5247: Improve error message when unknown format codes are

214 for ints and longs.
215
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000216- Issue #5260: Long integers now consume less memory: average
217 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
218 on a 64-bit system.
219
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000220- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
221 rotating the object pointer by 4 bits to the right.
222
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000223- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

225
Benjamin Petersone18ef192009-01-20 14:21:16 +0000226- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
227
Georg Brandl29c6a282009-04-05 20:23:13 +0000228- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000229 were suppressing all exceptions. These include list(), filter(), map(),
230 zip(), and bytearray().
231
Benjamin Peterson596d3062009-01-19 15:42:23 +0000232- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

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

Mark Dickinson826f3fe2008-12-05 21:55:28 +0000303- Issue #4445: Replace "sizeof(PyStringObject)" with
304 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
305 str instances. On a typical machine this saves 3 bytes of memory
306 (on average) per string allocation.
307
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000308- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Vinay Sajip213faca2008-12-03 23:22:58 +0000318- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000319 method on file objects with closefd=False. The file descriptor is still
320 kept open but the file object behaves like a closed file. The ``FileIO``
321 object also got a new readonly attribute ``closefd``.
322
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000323- Issue #4348: Some bytearray methods returned that didn't cause any change to

Georg Brandl7fb00ad2008-10-25 07:00:52 +0000342 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000344- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
345 returned a path longer than MAX_PATH. (But It's doubtful this code path is
346 really executed because I cannot move to such directory on win2k)
347
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000348- Issue #4069: When set.remove(element) is used with a set element, the element
349 is temporarily replaced with an equivalent frozenset. But the eventual
350 KeyError would always report the empty frozenset([]) as the missing key. Now
351 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000371- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
372 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
373 step. This avoids problems with counting UTF-8 bytes that ignores the effect
374 of using the replace error handler in PyUnicode_DecodeUTF8().
375
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000376- Issue #3739: The unicode-internal encoder now reports the number of characters

Antoine Pitrou4698d992009-05-31 14:20:14 +00001416- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
1417 regression tests in parallel, shortening the total runtime.
1418
Nick Coghlan5533ff62009-04-22 15:26:04 +00001419- Issue #5354: New test support function import_fresh_module() makes
1420 it easy to import both normal and optimised versions of modules.
1421 test_heapq and test_warnings have been adjusted to use it, tests for
1422 other modules with both C and Python implementations in the stdlib
1423 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00001431- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001432 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001433 from test support, which does the conversion.
1434
Guilherme Polob1a98de2009-01-28 20:03:26 +00001435- Issue #5083: New 'gui' resource for regrtest.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001529- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1530
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001531- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1532 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1533 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1534 ``printf`` function, whereas PyString_FromFormat has an independent
1535 implementation and uses "%zd" on all platforms for size_t values.
1536 This makes a difference on win64, where ``printf`` needs "%Id" to display
1537 64bit values.
1538
Benjamin Peterson97179b02008-09-09 20:55:01 +00001539- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1543 object; previously an int would be returned for small values. the __long__
1544 method is allowed to return either an int or a long, but the behaviour of
1545 float objects should not change to respect backward compatibility.
1546
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001547- Issue #3751: str.rpartition would perform a left-partition when called with
1548 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001553 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001554 was correctly parsed but parsing of subsequent arguments failed.
1555
Vinay Sajip35e3b032008-09-01 14:33:59 +00001556- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001557 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1558 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1559 when given a tuple of classes as second argument, were looking up
1560 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1561 type object.
1562
Neal Norwitz18aa3882008-08-24 05:04:52 +00001563- Fix crashes on memory allocation failure found with failmalloc.
1564
1565- Fix memory leaks found with valgrind and update suppressions file.
1566
1567- Fix compiler warnings in opt mode which would lead to invalid memory reads.

1632 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1633 for catch_warnings() also led to an improvement in the raising of a

1706-----------------
1707
Guido van Rossumf8402962008-08-20 15:01:50 +00001708- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1709 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1710 extensions do not automatically benefit from the class attribute
1711 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1712 to their tp_flags field if they care. This is a backwards
1713 compatibility feature; in 3.0, all types will use the cache by
1714 default.
1715
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001716- Keyword arguments can now follow starred arguments. (``f(a, *args,
1717 keyword=23)`` is now valid syntax.)
1718
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001719- ctypes function pointers that are COM methods have a boolean True
1720 value again.
1721
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001722- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1723 by denying s# to parse objects that have a releasebuffer procedure,
1724 and introducing s*.
1725
Georg Brandl1e13ea92008-08-11 09:07:59 +00001726- Issue #3537: Fix an assertion failure when an empty but presized dict
1727 object was stored in the freelist.
1728
Mark Dickinsonb6467572008-08-04 21:30:09 +00001729- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1730 ValueError consistently across platforms.
1731
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001732- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1733 (64bit Unix, for example), unichr() would truncate its argument and return
1734 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1735
Neal Norwitze7d8be82008-07-31 17:17:14 +00001736- Apply security patches from Apple.
1737
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001738- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1739 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1740
Antoine Pitrou92f82162008-07-25 22:22:08 +00001741- Issue #1819: function calls with several named parameters are now on
1742 average 35% faster (as measured by pybench).
1743
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001744- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1745 the python debugger steps into a class statement: the free variables (local
1746 variables defined in an outer scope) would be deleted from the outer scope.
1747
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001748- Issue #2620: Overflow checking when allocating or reallocating memory
1749 was not always being done properly in some python types and extension
1750 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1751 all been updated to perform better checks and places in the code that
1752 would previously leak memory on the error path when such an allocation
1753 failed have been fixed.

1759
Benjamin Petersone977ad42008-08-20 01:42:01 +00001760- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1761 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1762
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001763- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1764 version reported by these tools does not necessarily follow the python
1765 version numbering scheme, so the module is less strict when parsing it.
1766
Nick Coghlanf70385a2008-08-18 12:42:46 +00001767- Issue #2235: Added Py3k warnings for types which will become unhashable
1768 under the stricter __hash__ inheritance rules in 3.0. Several types
1769 which did not meet the rules for hash invariants and were already
1770 unhashable in 3.0 have now been explicitly flagged as unhashable in
1771 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1772 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1773
Brett Cannon88f801d2008-08-18 00:46:22 +00001774- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1775 imported into the module but exposed as part of the module's API.
1776

1782
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001783- Issue #3575: Incremental decoder's decode function now takes bytearray
1784 by using 's*' instead of 't#'.
1785
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001786- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001787 fails unicode conversion on 2nd parameter. (windows only)
1788
Facundo Batista94f243a2008-08-17 03:38:39 +00001789- Issue 2464. urllib2 now supports a malformation in the URL received
1790 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +00001794
Facundo Batistaeb90b782008-08-16 14:44:07 +00001795- Issue #2776: fixed small issue when handling an URL with double slash
1796 after a 302 response in the case of not going through a proxy.
1797
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001798- Issue #2676: in the email package, content-type parsing was hanging on
1799 pathological input because of quadratic or exponential behaviour of a
1800 regular expression.
1801
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001802- Issue #3476: binary buffered reading through the new "io" library is now
1803 thread-safe.
1804
Brett Cannonbf3157b2008-08-14 05:00:03 +00001805- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1806 since mimetools itself is deprecated. Because modules are cached, all
1807 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1808
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001809- Issue #3134: shutil referenced undefined WindowsError symbol.
1810
Robert Schuppenies14646332008-08-10 11:01:53 +00001811- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1812 menu entries were not deleted.
1813
Brett Cannon83e81842008-08-09 23:30:55 +00001814- Copied the implementation of reduce() to _functools.reduce() to have a
1815 version that did not raise a DeprecationWarning under -3.
1816
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001817- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1818 a MemoryError rather than silently stop the iteration.
1819
Guido van Rossum59ce9012008-08-09 14:55:34 +00001820- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1821 to _sre.compile() will now be rejected. This should not affect anybody
1822 since the re.compile() function never generates invalid re-bytecode.
1823
Skip Montanaroa032bf42008-08-08 22:52:51 +00001824- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1825 upon first access it can be automatically initialized from the csv file if
1826 it wasn't initialized during instantiation.
1827
Brett Cannon3aa2a492008-08-06 22:28:09 +00001828- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1829 the reload() built-in has been removed.
1830
Brett Cannon7e30b672008-08-04 21:52:25 +00001831- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001832 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1840 raised an AttributeError.
1841
Benjamin Peterson01a24322008-07-28 23:35:27 +00001842- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001843 asking for a specific length. This problem only affected files opened
1844 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001845

1868
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001869- Issue #3394: zipfile.writestr sets external attributes when passed a
1870 file name rather than a ZipInfo instance, so files are extracted with
1871 mode 0600 rather than 000 under Unix.
1872
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001873- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1874 argument in python 2.5, this broke code that subclassed Popen to include its
1875 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1883-------------
1884
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001885- Issue #2235: the C API function PyObject_HashNotImplemented and its
1886 interaction with the tp_hash slot (added in 2.6b2) are now documented
1887
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001888- Issue #643841: The language reference now provides more detailed
1889 coverage of the lookup process for special methods. The disclaimers
1890 regarding lack of coverage of new-style classes have also been
1891 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001899Core and Builtins
1900-----------------
1901
Georg Brandl3e483f62008-07-16 22:57:41 +00001902- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1903 its methods now allow for items objects that can be converted to
1904 an integer using operator.index().
1905
Mark Dickinson64b7e502008-07-16 09:40:03 +00001906- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1907 produced a ValueError instead of giving the correct float.
1908
Eric Smitha5fa5a22008-07-16 00:11:49 +00001909- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1910 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1911
Mark Dickinson7103aa42008-07-15 19:08:33 +00001912- Issue #3008: the float type has a new instance method 'float.hex'
1913 and a new class method 'float.fromhex' to convert floating-point
1914 numbers to and from hexadecimal strings, respectively.
1915
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001916- Issue #2235: __hash__ is once again inherited by default. To allow
1917 collections.Hashable to remain meaningful in the presence of the
1918 default hash implementation (object.__hash__), it is now possible
1919 to explicit block inheritance of hash by setting __hash__=None at
1920 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1921 level.
1922
Nick Coghlanb028f502008-07-13 14:52:36 +00001923- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1924 the parent module cannot be found while performing an absolute import.
1925 This means that an incorrectly defined __package__ attribute will
1926 now only prevent relative imports in that module rather than causing
1927 all imports from that module to fail.
1928
Nick Coghlan14ff9942008-07-08 14:21:42 +00001929- Issue #2517: Allow unicode messages in Exceptions again by correctly
1930 bypassing the instance dictionary when looking up __unicode__ on
1931 new-style classes.
1932
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001933- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1934 set to a custom object whose write() method happens to install
1935 another file in sys.stdout.
1936
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001937- Issue #3088: Corrected a race condition in classes derived from
1938 threading.local: the first member set by a thread could be saved in
1939 another thread's dictionary.
1940
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001941- Issue #3004: Minor change to slice.indices(): the start and stop
1942 arguments are now treated identically, making the behaviour easier
1943 to describe and understand. For example, slice(None, -10,
1944 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1945 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1946 10, -1).
1947
Georg Brandl278fc502008-07-19 12:46:12 +00001948- Issue #3219: Calling a function with repeated keyword arguments,
1949 f(a=2, a=23), would not cause a syntax error. This was a regression
1950 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001951
Georg Brandl278fc502008-07-19 12:46:12 +00001952- Issue #2862: Make int and float freelist management consistent with
1953 other freelists. Changes their CompactFreeList apis into
1954 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001955

1957-------
1958
Thomas Heller57adf222008-08-14 19:10:48 +00001959- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1960 api functions without holding the GIL, which could lead to a fatal
1961 error when they failed.
1962
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001963- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1972 ForkingPickler.register() to resolve conflict with ctypes.
1973
Vinay Sajip51e65192008-07-18 09:01:10 +00001974- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001975
Thomas Heller880f5292008-07-15 19:39:38 +00001976- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1977 a valid dlerror() message.
1978
Thomas Heller2bad6572008-07-15 17:19:50 +00001979- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1980 incomplete structure was created.
1981
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001982- Issue #3339: dummy_thread.acquire() should not return None.
1983
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001984- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1985
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001986- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001987
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001988- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1989 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001990 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001991 content-length. The problem had been corrected in the 2.4 branch, but never
1992 merged into trunk.
1993
Georg Brandle78fbcc2008-07-05 10:13:36 +00001994- Issue #2663: add filtering capability to shutil.copytree().

1999
2000- Issue #1746: Correct handling of zipfile archive comments (previously
2001 archives with comments over 4k were flagged as invalid). Allow writing

2397
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002398- On MacOS X it is now possible to install the framework in 64-bit
2399 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002400 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002401
2402 This is controlled by the configure argument ``--with-universal-archs``:
2403
2404 - ``--with-universal-archs=all``: install 4-way universal
2405
2406 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2407
2408 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2409
2410 This option should be used in combination with ``--enable-universalsdk=``.
2411
2412 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 +00002462- Issue #1631171: Re-implement the 'warnings' module in C (the
2463 original Python code has been kept as backup). This will allow for
2464 using the 'warning's machinery in such places as the parser where
2465 use of pure Python code is not possible. Both the ``showarning()``
2466 and ``formatwarning()`` gain an optional 'line' argument which is
2467 not called by default for backwards-compatibility reasons. Setting
2468 ``warnings.showwarning()`` to an implementation that lacks support
2469 for the ``line`` argument will raise a DeprecationWarning.

2493
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002494- The getpass module has been improved on Unix. It now uses /dev/tty
2495 by default and uses stderr instead of stdout. A GetPassWarning is
2496 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002511- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002512 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002532- Issue #2550: The approach used by client/server code for obtaining
2533 ports to listen on in network-oriented tests has been refined in an
2534 effort to facilitate running multiple instances of the entire
2535 regression test suite in parallel without issue.
2536 test_support.bind_port() has been fixed such that it will always
2537 return a unique port -- which wasn't always the case with the
2538 previous implementation, especially if socket options had been set
2539 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2540 new implementation of bind_port() will actually raise an exception
2541 if it is passed an AF_INET/SOCK_STREAM socket with either the
2542 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2543 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2544 the socket it's been passed. This currently only applies to
2545 Windows. This option prevents any other sockets from binding to the
2546 host/port we've bound to, thus removing the possibility of the
2547 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2548 when a second SOCK_STREAM socket binds and accepts to a host/port
2549 that's already been bound by another socket. The optional preferred
2550 port parameter to bind_port() has been removed. Under no
2551 circumstances should tests be hard coding ports!
2552
2553 test_support.find_unused_port() has also been introduced, which will
2554 pass a temporary socket object to bind_port() in order to obtain an
2555 unused port. The temporary socket object is then closed and
2556 deleted, and the port is returned. This method should only be used
2557 for obtaining an unused port in order to pass to an external program
2558 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2559 a parameter to a server-oriented class that doesn't give you direct
2560 access to the underlying socket used.
2561
2562 Finally, test_support.HOST has been introduced, which should be used
2563 for the host argument of any relevant socket calls (i.e. bind and
2564 connect).

2838Core and builtins
2839-----------------
2840
Fred Drakea8ee94b2008-03-01 02:45:07 +00002841- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002842 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002843
Georg Brandlad61bc82008-02-23 15:11:18 +00002844- Issue #2067: file.__exit__() now calls subclasses' close() method.
2845
2846- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002847
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002848- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002849 issue 215555 for a discussion.
2850
Eric Smitha73fbe72008-02-23 03:09:44 +00002851- Added the future_builtins module, which contains hex() and oct().
2852 These are the PEP 3127 version of these functions, designed to be
2853 compatible with the hex() and oct() builtins from Python 3.0. They
2854 differ slightly in their output formats from the existing, unchanged
2855 Python 2.6 builtins. The expected usage of the future_builtins
2856 module is:
2857 from future_builtins import hex, oct
2858
Eric Smith7ef40bf2008-02-20 23:34:22 +00002859- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2860 exponents for exponents with absolute value < 100. Follows C99
2861 standard. This is a change on Windows, which would use 3 digits.
2862 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2863 so that any alterations it does to the resulting string will be
2864 available in stringlib/formatter.h (for float.__format__).
2865
Eric Smith5a3c1352008-02-19 13:21:56 +00002866- Implemented PEP 3101, Advanced String Formatting. This adds a new
2867 builtin format(); a format() method for str and unicode; a
2868 __format__() method to object, str, unicode, int, long, float, and
2869 datetime; the class string.Formatter; and the C API
2870 PyObject_Format().
2871
Georg Brandl3ee81df2008-05-17 18:14:43 +00002872- Fixed several potential crashes, all caused by specially crafted
2873 __del__ methods exploiting objects in temporarily inconsistent
2874 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002875
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002876- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002877 prevent a possible crash: an Abstract Base Class would try to access
2878 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002879
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Fixed repr() and str() of complex numbers with infinity or nan as
2881 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002882
Georg Brandl3ee81df2008-05-17 18:14:43 +00002883- Clear all free lists during a gc.collect() of the highest generation
2884 in order to allow pymalloc to free more arenas. Python may give back
2885 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002886
Georg Brandl3ee81df2008-05-17 18:14:43 +00002887- Issue #2045: Fix an infinite recursion triggered when printing a
2888 subclass of collections.defaultdict, if its default_factory is set
2889 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002890
Christian Heimesf75dbef2008-02-08 00:11:31 +00002891- Fixed a minor memory leak in dictobject.c. The content of the free
2892 list was not freed on interpreter shutdown.
2893
Georg Brandl3ee81df2008-05-17 18:14:43 +00002894- Limit free list of method and builtin function objects to 256
2895 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002896
Georg Brandl3ee81df2008-05-17 18:14:43 +00002897- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2898 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002899 to compact the internal free lists of pre-allocted ints and floats.
2900
Georg Brandl3ee81df2008-05-17 18:14:43 +00002901- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2902 calls. Python expected the return type int but the fork familie
2903 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002904
Georg Brandl3ee81df2008-05-17 18:14:43 +00002905- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2906 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002907
Georg Brandl3ee81df2008-05-17 18:14:43 +00002908- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2909 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002910
Georg Brandl3ee81df2008-05-17 18:14:43 +00002911- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2912 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002913
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2915 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002916
Georg Brandl3ee81df2008-05-17 18:14:43 +00002917- Patch #1473257: generator objects gain a gi_code attribute. This is
2918 the same object as the func_code attribute of the function that
2919 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002920
Georg Brandl3ee81df2008-05-17 18:14:43 +00002921- Issue #1920: "while 0" statements were completely removed by the
2922 compiler, even in the presence of an "else" clause, which is
2923 supposed to be run when the condition is false. Now the compiler
2924 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002925
Guido van Rossumeead05f2008-01-24 18:21:02 +00002926- A few crashers fixed: weakref_in_del.py (issue #1377858);
2927 loosing_dict_ref.py (issue #1303614, test67.py);
2928 borrowed_ref_[34].py (not in tracker).
2929
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002930- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002931 suppressed while an extension is loaded by calling SetErrorMode in
2932 dynload_win.c. The error is still reported properly.
2933
Georg Brandl3ee81df2008-05-17 18:14:43 +00002934- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002935 several extension methods and modules do not work without unicode
2936 support.
2937
Georg Brandl26543b12008-01-21 18:36:51 +00002938- Issue #1882: when compiling code from a string, encoding cookies in the
2939 second line of code were not always recognized correctly.
2940
Georg Brandl14404b62008-01-19 19:27:05 +00002941- Issue #1679: "0x" was taken as a valid integer literal.
2942
Georg Brandl6caad7d2008-01-26 14:19:22 +00002943- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002944 added.
2945
Christian Heimesc94e2b52008-01-14 04:13:37 +00002946- sys.float_info / PyFloat_GetInfo: The floating point information
2947 object was converted from a dict to a specialized structseq object.
2948
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- Patch #1816: Added sys.flags structseq. It exposes the status of
2950 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002951
Georg Brandl3ee81df2008-05-17 18:14:43 +00002952- Objects/structseq.c: Implemented new structseq representation. The
2953 patch makes structseqs (e.g. the return value of os.stat) more
2954 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002955
Georg Brandl3ee81df2008-05-17 18:14:43 +00002956- Patch #1700288: added a type attribute cache that caches method
2957 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002958
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002959- Bug #1776: __import__() no longer accepts filenames on any platform.
2960 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002961
Georg Brandlaed6c662008-01-07 17:25:53 +00002962- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2963
Georg Brandl3ee81df2008-05-17 18:14:43 +00002964- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2965 envvar and sys.dont_write_bytecode attribute. All these can be set
2966 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002967
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968- Improve some exception messages when Windows fails to load an
2969 extension module. Now we get for example '%1 is not a valid Win32
2970 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002971
Georg Brandl3ee81df2008-05-17 18:14:43 +00002972- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002974- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2975 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002976
Christian Heimes0a8143f2007-12-18 23:22:54 +00002977- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002978 and INF. float("nan"), float("inf") and float("-inf") now work on
2979 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002980
Georg Brandl3ee81df2008-05-17 18:14:43 +00002981- Compiler now generates simpler and faster code for dictionary
2982 literals. The oparg for BUILD_MAP now indicates an estimated
2983 dictionary size. There is a new opcode, STORE_MAP, for adding
2984 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002985
Georg Brandl3ee81df2008-05-17 18:14:43 +00002986- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Issue #1620: New property decorator syntax was modifying the
2989 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002990
Georg Brandl3ee81df2008-05-17 18:14:43 +00002991- Issue #1538: Avoid copying string in split/rsplit if the split char
2992 is not found.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002994- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002995 SystemError.
2996
Nick Coghlanef01d822007-12-03 12:55:17 +00002997- PEP 366: Allow explicit relative imports when executing modules
2998 inside packages with the -m switch via a new module level
2999 __package__ attribute.
3000
Georg Brandl3ee81df2008-05-17 18:14:43 +00003001- Issue #1402: Fix a crash on exit, when another thread is still
3002 running, and if the deallocation of its frames somehow calls the
3003 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003004

3014 file can now be directly executed by passing their name to the
3015 interpreter. The directory/zipfile is automatically inserted as the
3016 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003017
Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Issue #1265: Fix a problem with sys.settrace, if the tracing
3019 function uses a generator expression when at the same time the
3020 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003021
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003022- sets and frozensets now have an isdisjoint() method.
3023
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003024- optimize the performance of builtin.sum().
3025
Neal Norwitz44f326e2007-10-05 05:29:17 +00003026- Fix warnings found by the new version of the Coverity checker.
3027
Georg Brandl3ee81df2008-05-17 18:14:43 +00003028- The enumerate() builtin function is no longer bounded to sequences
3029 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3030 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003031
Georg Brandl3ee81df2008-05-17 18:14:43 +00003032- Issue #1686386: Tuple's tp_repr did not take into account the
3033 possibility of having a self-referential tuple, which is possible
3034 from C code. Nor did object's tp_str consider that a type's tp_str
3035 could do something that could lead to an inifinite recursion.
3036 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3037 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003038
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039- Issue #1164: It was possible to trigger deadlock when using the
3040 'print' statement to write to a file since the GIL was not released
3041 as needed. Now PyObject_Print() does the right thing along with
3042 various tp_print implementations of the built-in types and those in
3043 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003044
Georg Brandl3ee81df2008-05-17 18:14:43 +00003045- Issue #1147: Exceptions were directly allowing string exceptions in
3046 their throw() method even though string exceptions no longer
3047 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003048
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003052- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053 PyObject_Call() never calling back out to Python code to trigger
3054 recursion depth updates/checks. Required the creation of a static
3055 RuntimeError instance in case normalizing an exception put the
3056 recursion check value past its limit. Fixes crashers
3057 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003072- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003073 __*__ attributes. (Some already existed, e.g., __doc__ and
3074 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003075
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003076- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00003083 "except E as target:". This is to provide forwards compatibility
3084 with Python 3.0.

3104
Guido van Rossum143b5642007-03-23 04:58:42 +00003105- Bug #1683368: The object.__init__() and object.__new__() methods are
3106 now stricter in rejecting excess arguments. The only time when
3107 either allows excess arguments is when it is not overridden and the
3108 other one is. For backwards compatibility, when both are
3109 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003110 warning later). Also, type.__init__() insists on the same signature
3111 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003112
Georg Brandl3ee81df2008-05-17 18:14:43 +00003113- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3114 object to complex using its __complex__() method before falling back
3115 to the __float__() method. Therefore, the functions in the cmath
3116 module now can operate on objects that define a __complex__()
3117 method.

3134
Georg Brandl7b9c5552007-03-12 14:30:05 +00003135- Bug #1678647: write a newline after printing an exception in any
3136 case, even when converting the value to a string failed.
3137
Georg Brandl871f1bc2007-03-12 13:17:36 +00003138- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139 its argument, if it exists. If not, it will work like before. This
3140 allows customizing the output of dir() in the presence of a
3141 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003142
Collin Winter276887b2007-03-12 16:11:39 +00003143- Patch #922167: Python no longer segfaults when faced with infinitely
3144 self-recursive reload() calls (as reported by bug #742342).

3151 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003152
Georg Brandlaa2321b2007-03-07 00:40:28 +00003153- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154 makes the filenames the warning module prints much more sensible
3155 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003156

Georg Brandl0fca97a2007-03-05 22:28:08 +00003168- Patch #1674228: when assigning a slice (old-style), check for the
3169 sq_ass_slice instead of the sq_slice slot.
3170
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003797- unittest now verifies more of its assumptions. In particular,
3798 TestCase and TestSuite subclasses (not instances) are no longer
3799 accepted in TestSuite.addTest(). This should cause no
3800 incompatibility since it never made sense with ordinary subclasses
3801 -- the failure just occurred later, with a more cumbersome
3802 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004083- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4084 with RFC 3207 and forgets any knowledge obtained from the server not
4085 obtained from the TLS negotiation itself. Patch contributed by Bill
4086 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004087
Georg Brandl3ee81df2008-05-17 18:14:43 +00004088- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004089 that the SMTP.starttls() caller no longer needs to call ehlo()
4090 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004091 does not claim to support starttls. Adds the
4092 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4173 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4174 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004191 time so that opening a database previously created with the DB_DUP
4192 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4193 opens. Specifically: dictionary assignment to a DB object will
4194 replace all values for a given key when the database allows
4195 duplicate values. DB users should use DB.put(k, v) when they want
4196 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004197

4203 characters with ASCII value less than 32. Also, it correctly quotes
4204 dots only if they occur on a single line, as opposed to the previous
4205 behavior of quoting dots if they are the second character of any
4206 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004207

Georg Brandl3ee81df2008-05-17 18:14:43 +00004536- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4537 to ``PyTuple_SetItem``, it can be used to populate a brand new
4538 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004542- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4543 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4544 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004545
4546- Patch #1720595: add T_BOOL to the range of structmember types.
4547

4550
Georg Brandl3ee81df2008-05-17 18:14:43 +00004551- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4552 of w# format code incorrectly truncated the length to an int, even
4553 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4554 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004555
Georg Brandl3ee81df2008-05-17 18:14:43 +00004556- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4557 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004559- PEP 3123: Provide forward compatibility with Python 3.0, while
4560 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4561 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004562
Georg Brandl3ee81df2008-05-17 18:14:43 +00004563- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4564 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004565
4566- Patch #1733960: Allow T_LONGLONG to accept ints.
4567
4568- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4569
Christian Heimes000a0742008-01-03 22:16:32 +00004570- Added a new API function ``PyImport_ImportModuleNoBlock``.
4571
Georg Brandl6caad7d2008-01-26 14:19:22 +00004572- Bug #1637022: Prefix AST symbols with _Py_.
4573
4574- Fix some leftovers from the conversion from int to Py_ssize_t
4575 (relevant to strings and sequences of more than 2**31 items).
4576
4577- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4578 outside of pystate.c and should not be necessary.
4579
Georg Brandl3ee81df2008-05-17 18:14:43 +00004580- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4581 absolute imports. In earlier versions they might have used relative
4582 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004583
Georg Brandl3ee81df2008-05-17 18:14:43 +00004584- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4585 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004586
Georg Brandl3ee81df2008-05-17 18:14:43 +00004587- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004594- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4595 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4596 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4597 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004598

Brett Cannon791d56f2007-05-31 19:40:42 +00004610- buildtools now raises a DeprecationWarning.
4611
Georg Brandl3ee81df2008-05-17 18:14:43 +00004612- Removed the macfs module. It had been deprecated since Python 2.5.
4613 This lead to the deprecation of macostools.touched() as it relied
4614 solely on macfs and was a no-op under OS X.
