96 (1) inf and nan strings with trailing whitespace were incorrectly
97 rejected; (2) parsing of strings representing infinities and nans
98 was locale aware; and (3) the interpretation of fromhex('-nan')
99 didn't match that of float('-nan').
100
Eric Smitha985a3a2009-05-05 18:26:08 +0000101- Issue #5920: For float.__format__, change the behavior with the
102 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
103 to be like 'g' but with at least one decimal point and with a
104 default precision of 12. Previously, the behavior the same but with
105 a default precision of 6. This more closely matches str(), and
106 reduces surprises when adding alignment flags to the empty
107 presentation type. This also affects the new complex.__format__ in
108 the same way.
109
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000110- Issue #5890: in subclasses of 'property' the __doc__ attribute was
111 shadowed by classtype's, even if it was None. property now
112 inserts the __doc__ into the subclass instance __dict__.
113

119
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000120- Issue #5864: Fix empty format code formatting for floats so that it
121 never gives more than the requested number of significant digits.
122
Eric Smithcac7af62009-04-27 19:04:37 +0000123- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

133
Mark Dickinson95bc9802009-04-24 12:46:53 +0000134- Issue #5816: complex(repr(z)) now recovers z exactly, even when
135 z involves nans, infs or negative zeros.
136
Eric Smithaca19e62009-04-22 13:29:05 +0000137- Implement PEP 378, Format Specifier for Thousands Separator, for
138 floats, ints, and longs.
139
140- Issue #5515: 'n' formatting for ints, longs, and floats handles
141 leading zero formatting poorly.
142

144 we're using no type code and we have an exponent.
145

150 some builtin types.
151
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000152- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000153 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000154
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000155- Issue #5759: float() didn't call __float__ on str subclasses.
156
Georg Brandl3c4a5462009-04-12 12:08:12 +0000157- Issue #5704: the "-3" command-line option now implies "-t".

170 the end sys.path, for compatibility with the system install of Python.
171
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000172- Issue #4688: Add a heuristic so that tuples and dicts containing only
173 untrackable objects are not tracked by the garbage collector. This can
174 reduce the size of collections and therefore the garbage collection overhead
175 on long-running programs, depending on their particular use of datatypes.
176
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000177- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
178 improve its performance. Long divisions and remainder operations
179 are now between 50% and 150% faster.
180
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000181- Issue #4258: Make it possible to use base 2**30 instead of base
182 2**15 for the internal representation of integers, for performance
183 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
184 --enable-big-digits option to configure, which overrides the
185 default. Add sys.long_info structseq to provide information about
186 the internal format.
187
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000188- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
189 result traceback.__members__ no longer exists.)
190
Mark Dickinson6b265f12009-03-18 16:07:26 +0000191- Issue #4474: PyUnicode_FromWideChar now converts characters outside
192 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
193 and sizeof(Py_UNICODE) == 2.
194
Eric Smith6f42edb2009-03-14 11:57:26 +0000195- Issue #5237: Allow auto-numbered fields in str.format(). For
196 example: '{} {}'.format(1, 2) == '1 2'.
197
Brett Cannon6c4cff02009-03-11 04:51:06 +0000198- Issue #3652: Make the 'line' argument for warnings.showwarning() a
199 requirement. Means the DeprecationWarning from Python 2.6 can go away.
200
Eric Smithe9fb6862009-02-20 14:02:36 +0000201- Issue #5247: Improve error message when unknown format codes are
202 used when using str.format() with str, unicode, long, int, and
203 float arguments.
204
Raymond Hettinger08259e82009-02-18 23:10:19 +0000205- Running Python with the -3 option now also warns about classic division
206 for ints and longs.
207
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000208- Issue #5260: Long integers now consume less memory: average
209 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
210 on a 64-bit system.
211
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000212- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
213 rotating the object pointer by 4 bits to the right.
214
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000215- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
216 it now forces its argument to double before testing for infinity.
217
Benjamin Petersone18ef192009-01-20 14:21:16 +0000218- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
219
Georg Brandl29c6a282009-04-05 20:23:13 +0000220- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000221 were suppressing all exceptions. These include list(), filter(), map(),
222 zip(), and bytearray().
223
Benjamin Peterson596d3062009-01-19 15:42:23 +0000224- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

242
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000243- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
244 collecting the oldest generation) so that allocating lots of objects without
245 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000246 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000247 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

252 an existing .py counterpart, override the co_filename attributes of all
253 code objects if the original filename is obsolete (which can happen if the
254 file has been renamed, moved, or if it is accessed through different paths).
255 Patch by Ziga Seilnacht and Jean-Paul Calderone.
256
Martin v. Löwis5344c992009-01-02 20:32:55 +0000257- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000311 method on file objects with closefd=False. The file descriptor is still
312 kept open but the file object behaves like a closed file. The ``FileIO``
313 object also got a new readonly attribute ``closefd``.
314

Georg Brandl7fb00ad2008-10-25 07:00:52 +0000334 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000336- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
337 returned a path longer than MAX_PATH. (But It's doubtful this code path is
338 really executed because I cannot move to such directory on win2k)
339
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000340- Issue #4069: When set.remove(element) is used with a set element, the element
341 is temporarily replaced with an equivalent frozenset. But the eventual
342 KeyError would always report the empty frozenset([]) as the missing key. Now
343 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000363- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
364 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
365 step. This avoids problems with counting UTF-8 bytes that ignores the effect
366 of using the replace error handler in PyUnicode_DecodeUTF8().
367
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000368- Issue #3739: The unicode-internal encoder now reports the number of characters

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001502- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1503
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001504- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1505 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1506 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1507 ``printf`` function, whereas PyString_FromFormat has an independent
1508 implementation and uses "%zd" on all platforms for size_t values.
1509 This makes a difference on win64, where ``printf`` needs "%Id" to display
1510 64bit values.
1511
Benjamin Peterson97179b02008-09-09 20:55:01 +00001512- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1516 object; previously an int would be returned for small values. the __long__
1517 method is allowed to return either an int or a long, but the behaviour of
1518 float objects should not change to respect backward compatibility.
1519
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001520- Issue #3751: str.rpartition would perform a left-partition when called with
1521 a unicode argument.
1522
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001523- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001526 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001527 was correctly parsed but parsing of subsequent arguments failed.
1528
Vinay Sajip35e3b032008-09-01 14:33:59 +00001529- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001530 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1531 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1532 when given a tuple of classes as second argument, were looking up
1533 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1534 type object.
1535
Neal Norwitz18aa3882008-08-24 05:04:52 +00001536- Fix crashes on memory allocation failure found with failmalloc.
1537
1538- Fix memory leaks found with valgrind and update suppressions file.
1539
1540- Fix compiler warnings in opt mode which would lead to invalid memory reads.

1605 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1606 for catch_warnings() also led to an improvement in the raising of a

1679-----------------
1680
Guido van Rossumf8402962008-08-20 15:01:50 +00001681- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1682 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1683 extensions do not automatically benefit from the class attribute
1684 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1685 to their tp_flags field if they care. This is a backwards
1686 compatibility feature; in 3.0, all types will use the cache by
1687 default.
1688
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001689- Keyword arguments can now follow starred arguments. (``f(a, *args,
1690 keyword=23)`` is now valid syntax.)
1691
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001692- ctypes function pointers that are COM methods have a boolean True
1693 value again.
1694
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001695- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1696 by denying s# to parse objects that have a releasebuffer procedure,
1697 and introducing s*.
1698
Georg Brandl1e13ea92008-08-11 09:07:59 +00001699- Issue #3537: Fix an assertion failure when an empty but presized dict
1700 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00001702- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1703 ValueError consistently across platforms.
1704
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001705- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1706 (64bit Unix, for example), unichr() would truncate its argument and return
1707 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1708
Neal Norwitze7d8be82008-07-31 17:17:14 +00001709- Apply security patches from Apple.
1710
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001711- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00001714- Issue #1819: function calls with several named parameters are now on
1715 average 35% faster (as measured by pybench).
1716
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001717- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1718 the python debugger steps into a class statement: the free variables (local
1719 variables defined in an outer scope) would be deleted from the outer scope.
1720
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001721- Issue #2620: Overflow checking when allocating or reallocating memory
1722 was not always being done properly in some python types and extension
1723 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1724 all been updated to perform better checks and places in the code that
1725 would previously leak memory on the error path when such an allocation
1726 failed have been fixed.

1732
Benjamin Petersone977ad42008-08-20 01:42:01 +00001733- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1734 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1735
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001736- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1737 version reported by these tools does not necessarily follow the python
1738 version numbering scheme, so the module is less strict when parsing it.
1739
Nick Coghlanf70385a2008-08-18 12:42:46 +00001740- Issue #2235: Added Py3k warnings for types which will become unhashable
1741 under the stricter __hash__ inheritance rules in 3.0. Several types
1742 which did not meet the rules for hash invariants and were already
1743 unhashable in 3.0 have now been explicitly flagged as unhashable in
1744 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1745 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1746
Brett Cannon88f801d2008-08-18 00:46:22 +00001747- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1748 imported into the module but exposed as part of the module's API.
1749

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001756- Issue #3575: Incremental decoder's decode function now takes bytearray
1757 by using 's*' instead of 't#'.
1758
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001759- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001760 fails unicode conversion on 2nd parameter. (windows only)
1761
Facundo Batista94f243a2008-08-17 03:38:39 +00001762- Issue 2464. urllib2 now supports a malformation in the URL received
1763 in a redirect.

Facundo Batistaeb90b782008-08-16 14:44:07 +00001768- Issue #2776: fixed small issue when handling an URL with double slash
1769 after a 302 response in the case of not going through a proxy.
1770
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001771- Issue #2676: in the email package, content-type parsing was hanging on
1772 pathological input because of quadratic or exponential behaviour of a
1773 regular expression.
1774
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001775- Issue #3476: binary buffered reading through the new "io" library is now
1776 thread-safe.
1777
Brett Cannonbf3157b2008-08-14 05:00:03 +00001778- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1779 since mimetools itself is deprecated. Because modules are cached, all
1780 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1781
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001782- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001784- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1785 menu entries were not deleted.
1786
Brett Cannon83e81842008-08-09 23:30:55 +00001787- Copied the implementation of reduce() to _functools.reduce() to have a
1788 version that did not raise a DeprecationWarning under -3.
1789
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001790- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1791 a MemoryError rather than silently stop the iteration.
1792
Guido van Rossum59ce9012008-08-09 14:55:34 +00001793- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1794 to _sre.compile() will now be rejected. This should not affect anybody
1795 since the re.compile() function never generates invalid re-bytecode.
1796
Skip Montanaroa032bf42008-08-08 22:52:51 +00001797- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1798 upon first access it can be automatically initialized from the csv file if
1799 it wasn't initialized during instantiation.
1800
Brett Cannon3aa2a492008-08-06 22:28:09 +00001801- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1802 the reload() built-in has been removed.
1803
Brett Cannon7e30b672008-08-04 21:52:25 +00001804- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001805 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1813 raised an AttributeError.
1814
Benjamin Peterson01a24322008-07-28 23:35:27 +00001815- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001816 asking for a specific length. This problem only affected files opened
1817 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001818

1841
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001842- Issue #3394: zipfile.writestr sets external attributes when passed a
1843 file name rather than a ZipInfo instance, so files are extracted with
1844 mode 0600 rather than 000 under Unix.
1845
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001846- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1847 argument in python 2.5, this broke code that subclassed Popen to include its
1848 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1857
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001858- Issue #2235: the C API function PyObject_HashNotImplemented and its
1859 interaction with the tp_hash slot (added in 2.6b2) are now documented
1860
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001861- Issue #643841: The language reference now provides more detailed
1862 coverage of the lookup process for special methods. The disclaimers
1863 regarding lack of coverage of new-style classes have also been
1864 removed, since the coverage is now fairly reasonable.

1868================================
1869
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001870*Release date: 17-Jul-2008*
1871
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001872Core and Builtins
1873-----------------
1874
Georg Brandl3e483f62008-07-16 22:57:41 +00001875- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1876 its methods now allow for items objects that can be converted to
1877 an integer using operator.index().
1878
Mark Dickinson64b7e502008-07-16 09:40:03 +00001879- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1880 produced a ValueError instead of giving the correct float.
1881
Eric Smitha5fa5a22008-07-16 00:11:49 +00001882- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1883 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1884
Mark Dickinson7103aa42008-07-15 19:08:33 +00001885- Issue #3008: the float type has a new instance method 'float.hex'
1886 and a new class method 'float.fromhex' to convert floating-point
1887 numbers to and from hexadecimal strings, respectively.
1888
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001889- Issue #2235: __hash__ is once again inherited by default. To allow
1890 collections.Hashable to remain meaningful in the presence of the
1891 default hash implementation (object.__hash__), it is now possible
1892 to explicit block inheritance of hash by setting __hash__=None at
1893 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1894 level.
1895
Nick Coghlanb028f502008-07-13 14:52:36 +00001896- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1897 the parent module cannot be found while performing an absolute import.
1898 This means that an incorrectly defined __package__ attribute will
1899 now only prevent relative imports in that module rather than causing
1900 all imports from that module to fail.
1901
Nick Coghlan14ff9942008-07-08 14:21:42 +00001902- Issue #2517: Allow unicode messages in Exceptions again by correctly
1903 bypassing the instance dictionary when looking up __unicode__ on
1904 new-style classes.
1905
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001906- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1907 set to a custom object whose write() method happens to install
1908 another file in sys.stdout.
1909
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001910- Issue #3088: Corrected a race condition in classes derived from
1911 threading.local: the first member set by a thread could be saved in
1912 another thread's dictionary.
1913
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001914- Issue #3004: Minor change to slice.indices(): the start and stop
1915 arguments are now treated identically, making the behaviour easier
1916 to describe and understand. For example, slice(None, -10,
1917 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1918 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1919 10, -1).
1920
Georg Brandl278fc502008-07-19 12:46:12 +00001921- Issue #3219: Calling a function with repeated keyword arguments,
1922 f(a=2, a=23), would not cause a syntax error. This was a regression
1923 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001924
Georg Brandl278fc502008-07-19 12:46:12 +00001925- Issue #2862: Make int and float freelist management consistent with
1926 other freelists. Changes their CompactFreeList apis into
1927 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001928

1930-------
1931
Thomas Heller57adf222008-08-14 19:10:48 +00001932- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1933 api functions without holding the GIL, which could lead to a fatal
1934 error when they failed.
1935
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001936- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001944- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1945 ForkingPickler.register() to resolve conflict with ctypes.
1946
Vinay Sajip51e65192008-07-18 09:01:10 +00001947- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001948
Thomas Heller880f5292008-07-15 19:39:38 +00001949- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1950 a valid dlerror() message.
1951
Thomas Heller2bad6572008-07-15 17:19:50 +00001952- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1953 incomplete structure was created.
1954
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001955- Issue #3339: dummy_thread.acquire() should not return None.

1958
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001959- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001960
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001961- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1962 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001963 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001964 content-length. The problem had been corrected in the 2.4 branch, but never
1965 merged into trunk.
1966
Georg Brandle78fbcc2008-07-05 10:13:36 +00001967- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001978 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001979
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001980- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1981 handling is now the same as that of other special attributes like __name__).
1982
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001983- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1984 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002373 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002374
2375 This is controlled by the configure argument ``--with-universal-archs``:
2376
2377 - ``--with-universal-archs=all``: install 4-way universal
2378
2379 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2380
2381 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2382
2383 This option should be used in combination with ``--enable-universalsdk=``.
2384
2385 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 +00002435- Issue #1631171: Re-implement the 'warnings' module in C (the
2436 original Python code has been kept as backup). This will allow for
2437 using the 'warning's machinery in such places as the parser where
2438 use of pure Python code is not possible. Both the ``showarning()``
2439 and ``formatwarning()`` gain an optional 'line' argument which is
2440 not called by default for backwards-compatibility reasons. Setting
2441 ``warnings.showwarning()`` to an implementation that lacks support
2442 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002505- Issue #2550: The approach used by client/server code for obtaining
2506 ports to listen on in network-oriented tests has been refined in an
2507 effort to facilitate running multiple instances of the entire
2508 regression test suite in parallel without issue.
2509 test_support.bind_port() has been fixed such that it will always
2510 return a unique port -- which wasn't always the case with the
2511 previous implementation, especially if socket options had been set
2512 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2513 new implementation of bind_port() will actually raise an exception
2514 if it is passed an AF_INET/SOCK_STREAM socket with either the
2515 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2516 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2517 the socket it's been passed. This currently only applies to
2518 Windows. This option prevents any other sockets from binding to the
2519 host/port we've bound to, thus removing the possibility of the
2520 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2521 when a second SOCK_STREAM socket binds and accepts to a host/port
2522 that's already been bound by another socket. The optional preferred
2523 port parameter to bind_port() has been removed. Under no
2524 circumstances should tests be hard coding ports!
2525
2526 test_support.find_unused_port() has also been introduced, which will
2527 pass a temporary socket object to bind_port() in order to obtain an
2528 unused port. The temporary socket object is then closed and
2529 deleted, and the port is returned. This method should only be used
2530 for obtaining an unused port in order to pass to an external program
2531 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2532 a parameter to a server-oriented class that doesn't give you direct
2533 access to the underlying socket used.
2534
2535 Finally, test_support.HOST has been introduced, which should be used
2536 for the host argument of any relevant socket calls (i.e. bind and
2537 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002538
2539 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002540 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002541 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2542 test_asynchat and test_socket_ssl.
2543
Georg Brandl3ee81df2008-05-17 18:14:43 +00002544 It is now possible for multiple instances of the regression test
2545 suite to run in parallel without issue.

2813
Fred Drakea8ee94b2008-03-01 02:45:07 +00002814- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002815 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002816
Georg Brandlad61bc82008-02-23 15:11:18 +00002817- Issue #2067: file.__exit__() now calls subclasses' close() method.
2818
2819- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002820
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002821- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002822 issue 215555 for a discussion.
2823
Eric Smitha73fbe72008-02-23 03:09:44 +00002824- Added the future_builtins module, which contains hex() and oct().
2825 These are the PEP 3127 version of these functions, designed to be
2826 compatible with the hex() and oct() builtins from Python 3.0. They
2827 differ slightly in their output formats from the existing, unchanged
2828 Python 2.6 builtins. The expected usage of the future_builtins
2829 module is:
2830 from future_builtins import hex, oct
2831
Eric Smith7ef40bf2008-02-20 23:34:22 +00002832- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2833 exponents for exponents with absolute value < 100. Follows C99
2834 standard. This is a change on Windows, which would use 3 digits.
2835 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2836 so that any alterations it does to the resulting string will be
2837 available in stringlib/formatter.h (for float.__format__).
2838
Eric Smith5a3c1352008-02-19 13:21:56 +00002839- Implemented PEP 3101, Advanced String Formatting. This adds a new
2840 builtin format(); a format() method for str and unicode; a
2841 __format__() method to object, str, unicode, int, long, float, and
2842 datetime; the class string.Formatter; and the C API
2843 PyObject_Format().
2844
Georg Brandl3ee81df2008-05-17 18:14:43 +00002845- Fixed several potential crashes, all caused by specially crafted
2846 __del__ methods exploiting objects in temporarily inconsistent
2847 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002848
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002849- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002850 prevent a possible crash: an Abstract Base Class would try to access
2851 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002852
Georg Brandl3ee81df2008-05-17 18:14:43 +00002853- Fixed repr() and str() of complex numbers with infinity or nan as
2854 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002855
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Clear all free lists during a gc.collect() of the highest generation
2857 in order to allow pymalloc to free more arenas. Python may give back
2858 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002859
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860- Issue #2045: Fix an infinite recursion triggered when printing a
2861 subclass of collections.defaultdict, if its default_factory is set
2862 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002863
Christian Heimesf75dbef2008-02-08 00:11:31 +00002864- Fixed a minor memory leak in dictobject.c. The content of the free
2865 list was not freed on interpreter shutdown.
2866
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867- Limit free list of method and builtin function objects to 256
2868 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002869
Georg Brandl3ee81df2008-05-17 18:14:43 +00002870- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2871 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002872 to compact the internal free lists of pre-allocted ints and floats.
2873
Georg Brandl3ee81df2008-05-17 18:14:43 +00002874- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2875 calls. Python expected the return type int but the fork familie
2876 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002877
Georg Brandl3ee81df2008-05-17 18:14:43 +00002878- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2879 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002880
Georg Brandl3ee81df2008-05-17 18:14:43 +00002881- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2882 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002883
Georg Brandl3ee81df2008-05-17 18:14:43 +00002884- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2885 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002886
Georg Brandl3ee81df2008-05-17 18:14:43 +00002887- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2888 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002889
Georg Brandl3ee81df2008-05-17 18:14:43 +00002890- Patch #1473257: generator objects gain a gi_code attribute. This is
2891 the same object as the func_code attribute of the function that
2892 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002893
Georg Brandl3ee81df2008-05-17 18:14:43 +00002894- Issue #1920: "while 0" statements were completely removed by the
2895 compiler, even in the presence of an "else" clause, which is
2896 supposed to be run when the condition is false. Now the compiler
2897 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002898
Guido van Rossumeead05f2008-01-24 18:21:02 +00002899- A few crashers fixed: weakref_in_del.py (issue #1377858);
2900 loosing_dict_ref.py (issue #1303614, test67.py);
2901 borrowed_ref_[34].py (not in tracker).
2902
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002903- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002904 suppressed while an extension is loaded by calling SetErrorMode in
2905 dynload_win.c. The error is still reported properly.
2906
Georg Brandl3ee81df2008-05-17 18:14:43 +00002907- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002908 several extension methods and modules do not work without unicode
2909 support.
2910
Georg Brandl26543b12008-01-21 18:36:51 +00002911- Issue #1882: when compiling code from a string, encoding cookies in the
2912 second line of code were not always recognized correctly.
2913
Georg Brandl14404b62008-01-19 19:27:05 +00002914- Issue #1679: "0x" was taken as a valid integer literal.
2915
Georg Brandl6caad7d2008-01-26 14:19:22 +00002916- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002917 added.
2918
Christian Heimesc94e2b52008-01-14 04:13:37 +00002919- sys.float_info / PyFloat_GetInfo: The floating point information
2920 object was converted from a dict to a specialized structseq object.
2921
Georg Brandl3ee81df2008-05-17 18:14:43 +00002922- Patch #1816: Added sys.flags structseq. It exposes the status of
2923 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002924
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925- Objects/structseq.c: Implemented new structseq representation. The
2926 patch makes structseqs (e.g. the return value of os.stat) more
2927 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002928
Georg Brandl3ee81df2008-05-17 18:14:43 +00002929- Patch #1700288: added a type attribute cache that caches method
2930 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002931
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002932- Bug #1776: __import__() no longer accepts filenames on any platform.
2933 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002934
Georg Brandlaed6c662008-01-07 17:25:53 +00002935- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2936
Georg Brandl3ee81df2008-05-17 18:14:43 +00002937- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2938 envvar and sys.dont_write_bytecode attribute. All these can be set
2939 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002940
Georg Brandl3ee81df2008-05-17 18:14:43 +00002941- Improve some exception messages when Windows fails to load an
2942 extension module. Now we get for example '%1 is not a valid Win32
2943 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002944
Georg Brandl3ee81df2008-05-17 18:14:43 +00002945- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002947- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2948 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002949
Christian Heimes0a8143f2007-12-18 23:22:54 +00002950- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002951 and INF. float("nan"), float("inf") and float("-inf") now work on
2952 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002953
Georg Brandl3ee81df2008-05-17 18:14:43 +00002954- Compiler now generates simpler and faster code for dictionary
2955 literals. The oparg for BUILD_MAP now indicates an estimated
2956 dictionary size. There is a new opcode, STORE_MAP, for adding
2957 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002958
Georg Brandl3ee81df2008-05-17 18:14:43 +00002959- Issue #1638: %zd configure test fails on Linux.

2987 file can now be directly executed by passing their name to the
2988 interpreter. The directory/zipfile is automatically inserted as the
2989 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002990
Georg Brandl3ee81df2008-05-17 18:14:43 +00002991- Issue #1265: Fix a problem with sys.settrace, if the tracing
2992 function uses a generator expression when at the same time the
2993 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002994
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002995- sets and frozensets now have an isdisjoint() method.
2996
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002997- optimize the performance of builtin.sum().
2998
Neal Norwitz44f326e2007-10-05 05:29:17 +00002999- Fix warnings found by the new version of the Coverity checker.
3000
Georg Brandl3ee81df2008-05-17 18:14:43 +00003001- The enumerate() builtin function is no longer bounded to sequences
3002 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3003 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003004
Georg Brandl3ee81df2008-05-17 18:14:43 +00003005- Issue #1686386: Tuple's tp_repr did not take into account the
3006 possibility of having a self-referential tuple, which is possible
3007 from C code. Nor did object's tp_str consider that a type's tp_str
3008 could do something that could lead to an inifinite recursion.
3009 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3010 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003011
Georg Brandl3ee81df2008-05-17 18:14:43 +00003012- Issue #1164: It was possible to trigger deadlock when using the
3013 'print' statement to write to a file since the GIL was not released
3014 as needed. Now PyObject_Print() does the right thing along with
3015 various tp_print implementations of the built-in types and those in
3016 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003017
Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Issue #1147: Exceptions were directly allowing string exceptions in
3019 their throw() method even though string exceptions no longer
3020 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003021
Georg Brandl3ee81df2008-05-17 18:14:43 +00003022- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003025- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003026 PyObject_Call() never calling back out to Python code to trigger
3027 recursion depth updates/checks. Required the creation of a static
3028 RuntimeError instance in case normalizing an exception put the
3029 recursion check value past its limit. Fixes crashers
3030 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003031
Georg Brandl3ee81df2008-05-17 18:14:43 +00003032- Patch #1031213: Decode source line in SyntaxErrors back to its

Georg Brandl3ee81df2008-05-17 18:14:43 +00003046 __*__ attributes. (Some already existed, e.g., __doc__ and
3047 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003048
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003049- Add -3 option to the interpreter to warn about features that are
3050 deprecated and will be changed/removed in Python 3.0.
3051
Georg Brandl2134e752007-05-21 20:34:16 +00003052- Patch #1686487: you can now pass any mapping after '**' in function
3053 calls.
3054
Collin Winter62903052007-05-18 23:11:24 +00003055- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056 "except E as target:". This is to provide forwards compatibility
3057 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003058
Brett Cannon229cee22007-05-05 01:34:02 +00003059- Deprecate BaseException.message as per PEP 352.
3060
Georg Brandl3ee81df2008-05-17 18:14:43 +00003061- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003062 inherited from a builtin base.
3063
Vinay Sajip8549ce32007-05-06 17:53:37 +00003064- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003065 setting a plain string, ie don't expand to single letter identifiers.
3066
Raymond Hettinger13936692007-04-11 18:40:58 +00003067- Request #1191699: Slices can now be pickled.

3077
Guido van Rossum143b5642007-03-23 04:58:42 +00003078- Bug #1683368: The object.__init__() and object.__new__() methods are
3079 now stricter in rejecting excess arguments. The only time when
3080 either allows excess arguments is when it is not overridden and the
3081 other one is. For backwards compatibility, when both are
3082 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003083 warning later). Also, type.__init__() insists on the same signature
3084 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003085
Georg Brandl3ee81df2008-05-17 18:14:43 +00003086- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3087 object to complex using its __complex__() method before falling back
3088 to the __float__() method. Therefore, the functions in the cmath
3089 module now can operate on objects that define a __complex__()
3090 method.

3107
Georg Brandl7b9c5552007-03-12 14:30:05 +00003108- Bug #1678647: write a newline after printing an exception in any
3109 case, even when converting the value to a string failed.
3110
Georg Brandl871f1bc2007-03-12 13:17:36 +00003111- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003112 its argument, if it exists. If not, it will work like before. This
3113 allows customizing the output of dir() in the presence of a
3114 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003116- Patch #922167: Python no longer segfaults when faced with infinitely
3117 self-recursive reload() calls (as reported by bug #742342).

3123 parthensized forms. This means complex(repr(x)) now works instead of
3124 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003125
Georg Brandlaa2321b2007-03-07 00:40:28 +00003126- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003127 makes the filenames the warning module prints much more sensible
3128 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003129

Georg Brandl0fca97a2007-03-05 22:28:08 +00003141- Patch #1674228: when assigning a slice (old-style), check for the
3142 sq_ass_slice instead of the sq_slice slot.
3143
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144- When printing an unraisable error, don't print exceptions. before

3155 created a weakref on itself during a __del__ call for new-style
3156 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003247 generator expressions (x for x, in ... ) works again. Fixing this
3248 problem required changing the .pyc magic number. This means that
3249 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003679 AttributeError instead of an IOError when the server's response

3771 TestCase and TestSuite subclasses (not instances) are no longer

3774 -- the failure just occurred later, with a more cumbersome
3775 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004056- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4057 with RFC 3207 and forgets any knowledge obtained from the server not
4058 obtained from the TLS negotiation itself. Patch contributed by Bill
4059 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004060
Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004062 that the SMTP.starttls() caller no longer needs to call ehlo()
4063 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004064 does not claim to support starttls. Adds the
4065 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4146 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4147 silently miscode subclasses of those types. Now, it raises a
4148 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004149

Georg Brandl3ee81df2008-05-17 18:14:43 +00004164 time so that opening a database previously created with the DB_DUP
4165 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4166 opens. Specifically: dictionary assignment to a DB object will
4167 replace all values for a given key when the database allows
4168 duplicate values. DB users should use DB.put(k, v) when they want
4169 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004170

4176 characters with ASCII value less than 32. Also, it correctly quotes
4177 dots only if they occur on a single line, as opposed to the previous
4178 behavior of quoting dots if they are the second character of any
4179 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004180

Georg Brandl3ee81df2008-05-17 18:14:43 +00004585- Removed the macfs module. It had been deprecated since Python 2.5.
4586 This lead to the deprecation of macostools.touched() as it relied
4587 solely on macfs and was a no-op under OS X.
