152 rejected; (2) parsing of strings representing infinities and nans
153 was locale aware; and (3) the interpretation of fromhex('-nan')
154 didn't match that of float('-nan').
155
Eric Smitha985a3a2009-05-05 18:26:08 +0000156- Issue #5920: For float.__format__, change the behavior with the
157 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
158 to be like 'g' but with at least one decimal point and with a
159 default precision of 12. Previously, the behavior the same but with
160 a default precision of 6. This more closely matches str(), and
161 reduces surprises when adding alignment flags to the empty
162 presentation type. This also affects the new complex.__format__ in
163 the same way.
164
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000165- Issue #5890: in subclasses of 'property' the __doc__ attribute was

174
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000175- Issue #5864: Fix empty format code formatting for floats so that it

Mark Dickinson95bc9802009-04-24 12:46:53 +0000189- Issue #5816: complex(repr(z)) now recovers z exactly, even when
190 z involves nans, infs or negative zeros.
191
Eric Smithaca19e62009-04-22 13:29:05 +0000192- Implement PEP 378, Format Specifier for Thousands Separator, for
193 floats, ints, and longs.
194
195- Issue #5515: 'n' formatting for ints, longs, and floats handles
196 leading zero formatting poorly.
197
198- Issue #5772: For float.__format__, don't add a trailing ".0" if
199 we're using no type code and we have an exponent.

206
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000207- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000208 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000209
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000210- Issue #5759: float() didn't call __float__ on str subclasses.

228 untrackable objects are not tracked by the garbage collector. This can
229 reduce the size of collections and therefore the garbage collection overhead
230 on long-running programs, depending on their particular use of datatypes.
231
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000232- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

237 2**15 for the internal representation of integers, for performance
238 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
239 --enable-big-digits option to configure, which overrides the
240 default. Add sys.long_info structseq to provide information about
241 the internal format.

252
Brett Cannon6c4cff02009-03-11 04:51:06 +0000253- Issue #3652: Make the 'line' argument for warnings.showwarning() a
254 requirement. Means the DeprecationWarning from Python 2.6 can go away.

265 on a 64-bit system.
266
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000267- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

274
Georg Brandl29c6a282009-04-05 20:23:13 +0000275- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000276 were suppressing all exceptions. These include list(), filter(), map(),

305
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000306- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
307 an existing .py counterpart, override the co_filename attributes of all
308 code objects if the original filename is obsolete (which can happen if the
309 file has been renamed, moved, or if it is accessed through different paths).
310 Patch by Ziga Seilnacht and Jean-Paul Calderone.
311
Martin v. Löwis5344c992009-01-02 20:32:55 +0000312- Issue #4075: Use OutputDebugStringW in Py_FatalError.
313
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000314- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
315 file with `str' filename on Windows.
316
Antoine Pitrouaa687902009-01-01 14:11:22 +0000317- Issue #3680: Reference cycles created through a dict, set or deque iterator
318 did not get collected.
319
Nick Coghlan180e4002008-12-30 01:18:48 +0000320- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
321 where the tp_hash and tp_dict slots are both NULL.
322
Benjamin Peterson7af65562008-12-29 17:56:58 +0000323- Issue #4764: With io.open, IOError.filename is set when trying to open a
324 directory on POSIX systems.
325
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000326- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
327 systems.
328
Georg Brandl6425a2f2008-12-28 11:54:53 +0000329- Issue #4759: None is now allowed as the first argument of
330 bytearray.translate(). It was always allowed for bytes.translate().
331
Skip Montanarof205c132008-12-23 03:30:15 +0000332- Added test case to ensure attempts to read from a file opened for writing
333 fail.
334
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000335- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
336 print elapsed times, not only when some objects are uncollectable /
337 unreachable. Original patch by Neil Schemenauer.

345 context manager returns a value that cannot be converted to a bool.
346
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000347- Issue #4597: Fixed several opcodes that weren't always propagating
348 exceptions.
349
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000350- Issue #4445: Replace "sizeof(PyStringObject)" with
351 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
352 str instances. On a typical machine this saves 3 bytes of memory
353 (on average) per string allocation.
354
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000355- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
356 interpreter to abort ("Fatal Python error: Could not reset the stack!")
357 instead of throwing a MemoryError.
358
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000359- Issue #3689: The list reversed iterator now supports __length_hint__

363 module couldn't be imported and \N escapes were present.
364
Vinay Sajip213faca2008-12-03 23:22:58 +0000365- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000366 method on file objects with closefd=False. The file descriptor is still
367 kept open but the file object behaves like a closed file. The ``FileIO``
368 object also got a new readonly attribute ``closefd``.
369
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000370- Issue #4348: Some bytearray methods returned that didn't cause any change to
371 the bytearray, returned the same bytearray instead of a copy.
372
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000373- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

378
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000379- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
380 exec statement.
381
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000382- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
383 method does not return iterators for the 4th and 5th items.
384
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000385- Issue #4209: Enabling unicode_literals and the print_function in the same
386 __future__ import didn't work.
387
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000388- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000389 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000390
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000391- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
392 returned a path longer than MAX_PATH. (But It's doubtful this code path is
393 really executed because I cannot move to such directory on win2k)
394
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000395- Issue #4069: When set.remove(element) is used with a set element, the element
396 is temporarily replaced with an equivalent frozenset. But the eventual
397 KeyError would always report the empty frozenset([]) as the missing key. Now
398 it correctly refers to the initial element.
399
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000400- Issue #4509: Various issues surrounding resize of bytearray objects to
401 which there are buffer exports.

410 short file names.
411

413 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000414
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000415- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
416 returned them on 64bit platforms.
417
Walter Dörwalded960ac2009-05-03 22:36:33 +0000418- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
419 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
420 step. This avoids problems with counting UTF-8 bytes that ignores the effect
421 of using the replace error handler in PyUnicode_DecodeUTF8().
422
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000423- Issue #3739: The unicode-internal encoder now reports the number of characters
424 consumed like any other encoder (instead of the number of bytes).

Gregory P. Smith38f5d8f2009-11-01 18:33:55 +0000429- Issue #7246 & Issue #7208: getpass now properly flushes input before
430 reading from stdin so that existing input does not confuse it and
431 lead to incorrect entry or an IOError. It also properly flushes it
432 afterwards to avoid the terminal echoing the input afterwards on
433 OSes such as Solaris.
434
Mark Dickinson6f390012009-10-29 12:11:18 +0000435- Issue #7233: Fix a number of two-argument Decimal methods to make
436 sure that they accept an int or long as the second argument. Also
437 fix buggy handling of large arguments (those with coefficient longer
438 than the current precision) in shift and rotate.

870 allows for much simpler resource allocation and deallocation during tests.
871
872- Issue #3379: unittest.main now takes an optional exit argument. If False main

940
941- The unittest.TestCase.assertEqual() now displays the differences in lists,

1545 leak-chasing test runs give sensible results. The previous method of
1546 reaping threads could return successfully while some Thread objects were
1547 still referenced. This also introduces a new private function:

1555
R. David Murray14dcd432009-10-14 13:58:07 +00001556- Issue #7058: Added save/restore for things like sys.argv and cwd to

1566 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1567 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1568 skip the tests if DISPLAY is defined but can't be used.
1569
Antoine Pitrou4698d992009-05-31 14:20:14 +00001570- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

1574 it easy to import both normal and optimised versions of modules.
1575 test_heapq and test_warnings have been adjusted to use it, tests for
1576 other modules with both C and Python implementations in the stdlib
1577 can be adjusted to use it over time.
1578

1584
R. David Murray41448c52009-03-31 19:57:24 +00001585- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001586 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001587 from test support, which does the conversion.

1697 object; previously an int would be returned for small values. the __long__
1698 method is allowed to return either an int or a long, but the behaviour of
1699 float objects should not change to respect backward compatibility.
1700
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001701- Issue #3751: str.rpartition would perform a left-partition when called with
1702 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001706- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001707 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001708 was correctly parsed but parsing of subsequent arguments failed.
1709
Vinay Sajip35e3b032008-09-01 14:33:59 +00001710- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001711 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1712 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1713 when given a tuple of classes as second argument, were looking up
1714 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1715 type object.
1716
Neal Norwitz18aa3882008-08-24 05:04:52 +00001717- Fix crashes on memory allocation failure found with failmalloc.

1786 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1787 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001854What's New in Python 2.6 beta 3?
1855================================
1856
Barry Warsaw07a4a382008-08-21 01:15:08 +00001857*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001858
1859Core and Builtins
1860-----------------
1861
Guido van Rossumf8402962008-08-20 15:01:50 +00001862- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1863 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1864 extensions do not automatically benefit from the class attribute
1865 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1866 to their tp_flags field if they care. This is a backwards
1867 compatibility feature; in 3.0, all types will use the cache by
1868 default.
1869
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001870- Keyword arguments can now follow starred arguments. (``f(a, *args,
1871 keyword=23)`` is now valid syntax.)
1872
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001873- ctypes function pointers that are COM methods have a boolean True
1874 value again.
1875
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001876- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1877 by denying s# to parse objects that have a releasebuffer procedure,
1878 and introducing s*.
1879
Georg Brandl1e13ea92008-08-11 09:07:59 +00001880- Issue #3537: Fix an assertion failure when an empty but presized dict
1881 object was stored in the freelist.
1882
Mark Dickinsonb6467572008-08-04 21:30:09 +00001883- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1884 ValueError consistently across platforms.
1885
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001886- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1887 (64bit Unix, for example), unichr() would truncate its argument and return
1888 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1889
Neal Norwitze7d8be82008-07-31 17:17:14 +00001890- Apply security patches from Apple.
1891
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001892- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1893 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1894
Antoine Pitrou92f82162008-07-25 22:22:08 +00001895- Issue #1819: function calls with several named parameters are now on
1896 average 35% faster (as measured by pybench).
1897
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001898- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1899 the python debugger steps into a class statement: the free variables (local
1900 variables defined in an outer scope) would be deleted from the outer scope.
1901
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001902- Issue #2620: Overflow checking when allocating or reallocating memory
1903 was not always being done properly in some python types and extension
1904 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1905 all been updated to perform better checks and places in the code that
1906 would previously leak memory on the error path when such an allocation
1907 failed have been fixed.

1911
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001912- Issue #3612: Added some missing basic types in ctypes.wintypes.
1913
Benjamin Petersone977ad42008-08-20 01:42:01 +00001914- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1915 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1916
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001917- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1918 version reported by these tools does not necessarily follow the python
1919 version numbering scheme, so the module is less strict when parsing it.
1920
Nick Coghlanf70385a2008-08-18 12:42:46 +00001921- Issue #2235: Added Py3k warnings for types which will become unhashable
1922 under the stricter __hash__ inheritance rules in 3.0. Several types
1923 which did not meet the rules for hash invariants and were already
1924 unhashable in 3.0 have now been explicitly flagged as unhashable in
1925 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1926 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1927
Brett Cannon88f801d2008-08-18 00:46:22 +00001928- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1929 imported into the module but exposed as part of the module's API.
1930
Brett Cannon7b96f072008-08-18 00:41:11 +00001931- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1932
Brett Cannon46225e72008-08-18 00:36:52 +00001933- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001935- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1936
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001937- Issue #3575: Incremental decoder's decode function now takes bytearray
1938 by using 's*' instead of 't#'.
1939
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001940- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001941 fails unicode conversion on 2nd parameter. (windows only)
1942
Facundo Batista94f243a2008-08-17 03:38:39 +00001943- Issue 2464. urllib2 now supports a malformation in the URL received
1944 in a redirect.
1945
Brett Cannonabe423e2008-08-16 21:47:07 +00001946- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001947 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001948
Facundo Batistaeb90b782008-08-16 14:44:07 +00001949- Issue #2776: fixed small issue when handling an URL with double slash
1950 after a 302 response in the case of not going through a proxy.
1951
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001952- Issue #2676: in the email package, content-type parsing was hanging on
1953 pathological input because of quadratic or exponential behaviour of a
1954 regular expression.
1955
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001956- Issue #3476: binary buffered reading through the new "io" library is now
1957 thread-safe.
1958
Brett Cannonbf3157b2008-08-14 05:00:03 +00001959- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1960 since mimetools itself is deprecated. Because modules are cached, all
1961 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1962
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001963- Issue #3134: shutil referenced undefined WindowsError symbol.
1964
Robert Schuppenies14646332008-08-10 11:01:53 +00001965- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1966 menu entries were not deleted.
1967
Brett Cannon83e81842008-08-09 23:30:55 +00001968- Copied the implementation of reduce() to _functools.reduce() to have a
1969 version that did not raise a DeprecationWarning under -3.
1970
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001971- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1972 a MemoryError rather than silently stop the iteration.
1973
Guido van Rossum59ce9012008-08-09 14:55:34 +00001974- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1975 to _sre.compile() will now be rejected. This should not affect anybody
1976 since the re.compile() function never generates invalid re-bytecode.
1977
Skip Montanaroa032bf42008-08-08 22:52:51 +00001978- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1979 upon first access it can be automatically initialized from the csv file if
1980 it wasn't initialized during instantiation.
1981
Brett Cannon3aa2a492008-08-06 22:28:09 +00001982- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1983 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00001997 asking for a specific length. This problem only affected files opened
1998 using the new "io" module, not the built-in open() function.

2054-----------------
2055
Georg Brandl3e483f62008-07-16 22:57:41 +00002056- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2057 its methods now allow for items objects that can be converted to
2058 an integer using operator.index().
2059
Mark Dickinson64b7e502008-07-16 09:40:03 +00002060- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2061 produced a ValueError instead of giving the correct float.
2062
Eric Smitha5fa5a22008-07-16 00:11:49 +00002063- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2064 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2065
Mark Dickinson7103aa42008-07-15 19:08:33 +00002066- Issue #3008: the float type has a new instance method 'float.hex'
2067 and a new class method 'float.fromhex' to convert floating-point
2068 numbers to and from hexadecimal strings, respectively.
2069
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002070- Issue #2235: __hash__ is once again inherited by default. To allow
2071 collections.Hashable to remain meaningful in the presence of the
2072 default hash implementation (object.__hash__), it is now possible
2073 to explicit block inheritance of hash by setting __hash__=None at
2074 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2075 level.
2076
Nick Coghlanb028f502008-07-13 14:52:36 +00002077- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2078 the parent module cannot be found while performing an absolute import.
2079 This means that an incorrectly defined __package__ attribute will
2080 now only prevent relative imports in that module rather than causing
2081 all imports from that module to fail.
2082
Nick Coghlan14ff9942008-07-08 14:21:42 +00002083- Issue #2517: Allow unicode messages in Exceptions again by correctly

2093 another thread's dictionary.
2094
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002095- Issue #3004: Minor change to slice.indices(): the start and stop
2096 arguments are now treated identically, making the behaviour easier
2097 to describe and understand. For example, slice(None, -10,
2098 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2099 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2100 10, -1).
2101
Georg Brandl278fc502008-07-19 12:46:12 +00002102- Issue #3219: Calling a function with repeated keyword arguments,
2103 f(a=2, a=23), would not cause a syntax error. This was a regression
2104 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002105
Georg Brandl278fc502008-07-19 12:46:12 +00002106- Issue #2862: Make int and float freelist management consistent with
2107 other freelists. Changes their CompactFreeList apis into

2115 error when they failed.
2116
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002117- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002142- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2143 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002144 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002145 content-length. The problem had been corrected in the 2.4 branch, but never
2146 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002161- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2162 handling is now the same as that of other special attributes like __name__).
2163
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002164- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002552- On MacOS X it is now possible to install the framework in 64-bit
2553 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002554 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002555
2556 This is controlled by the configure argument ``--with-universal-archs``:
2557
2558 - ``--with-universal-archs=all``: install 4-way universal
2559
2560 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2561
2562 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2563
2564 This option should be used in combination with ``--enable-universalsdk=``.
2565
2566 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2571
Georg Brandl74a1dea2008-05-28 11:21:39 +00002572- Add ``PyType_Modified()`` as a public API to clear the type cache.
2573
2574- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002575
2576- The PyString functions have been renamed to PyBytes. A batch of
2577 defines were added so that the linker still sees the original
2578 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002616- Issue #1631171: Re-implement the 'warnings' module in C (the
2617 original Python code has been kept as backup). This will allow for
2618 using the 'warning's machinery in such places as the parser where
2619 use of pure Python code is not possible. Both the ``showarning()``
2620 and ``formatwarning()`` gain an optional 'line' argument which is
2621 not called by default for backwards-compatibility reasons. Setting
2622 ``warnings.showwarning()`` to an implementation that lacks support
2623 for the ``line`` argument will raise a DeprecationWarning.

2647
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002648- The getpass module has been improved on Unix. It now uses /dev/tty
2649 by default and uses stderr instead of stdout. A GetPassWarning is
2650 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002665- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002666 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002686- Issue #2550: The approach used by client/server code for obtaining
2687 ports to listen on in network-oriented tests has been refined in an
2688 effort to facilitate running multiple instances of the entire
2689 regression test suite in parallel without issue.
2690 test_support.bind_port() has been fixed such that it will always
2691 return a unique port -- which wasn't always the case with the
2692 previous implementation, especially if socket options had been set
2693 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2694 new implementation of bind_port() will actually raise an exception
2695 if it is passed an AF_INET/SOCK_STREAM socket with either the
2696 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2697 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2698 the socket it's been passed. This currently only applies to
2699 Windows. This option prevents any other sockets from binding to the
2700 host/port we've bound to, thus removing the possibility of the
2701 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2702 when a second SOCK_STREAM socket binds and accepts to a host/port
2703 that's already been bound by another socket. The optional preferred
2704 port parameter to bind_port() has been removed. Under no
2705 circumstances should tests be hard coding ports!
2706
2707 test_support.find_unused_port() has also been introduced, which will
2708 pass a temporary socket object to bind_port() in order to obtain an
2709 unused port. The temporary socket object is then closed and
2710 deleted, and the port is returned. This method should only be used
2711 for obtaining an unused port in order to pass to an external program
2712 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2713 a parameter to a server-oriented class that doesn't give you direct
2714 access to the underlying socket used.
2715
2716 Finally, test_support.HOST has been introduced, which should be used
2717 for the host argument of any relevant socket calls (i.e. bind and
2718 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002719
2720 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002721 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002722 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2723 test_asynchat and test_socket_ssl.
2724
Georg Brandl3ee81df2008-05-17 18:14:43 +00002725 It is now possible for multiple instances of the regression test
2726 suite to run in parallel without issue.

2993-----------------
2994
Fred Drakea8ee94b2008-03-01 02:45:07 +00002995- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002996 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003001
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003002- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003003 issue 215555 for a discussion.
3004
Eric Smitha73fbe72008-02-23 03:09:44 +00003005- Added the future_builtins module, which contains hex() and oct().
3006 These are the PEP 3127 version of these functions, designed to be
3007 compatible with the hex() and oct() builtins from Python 3.0. They
3008 differ slightly in their output formats from the existing, unchanged
3009 Python 2.6 builtins. The expected usage of the future_builtins
3010 module is:
3011 from future_builtins import hex, oct
3012
Eric Smith7ef40bf2008-02-20 23:34:22 +00003013- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3014 exponents for exponents with absolute value < 100. Follows C99
3015 standard. This is a change on Windows, which would use 3 digits.
3016 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3017 so that any alterations it does to the resulting string will be
3018 available in stringlib/formatter.h (for float.__format__).
3019
Eric Smith5a3c1352008-02-19 13:21:56 +00003020- Implemented PEP 3101, Advanced String Formatting. This adds a new
3021 builtin format(); a format() method for str and unicode; a
3022 __format__() method to object, str, unicode, int, long, float, and
3023 datetime; the class string.Formatter; and the C API
3024 PyObject_Format().
3025
Georg Brandl3ee81df2008-05-17 18:14:43 +00003026- Fixed several potential crashes, all caused by specially crafted
3027 __del__ methods exploiting objects in temporarily inconsistent
3028 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003029
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003030- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003031 prevent a possible crash: an Abstract Base Class would try to access
3032 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003037- Clear all free lists during a gc.collect() of the highest generation
3038 in order to allow pymalloc to free more arenas. Python may give back
3039 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003040
Georg Brandl3ee81df2008-05-17 18:14:43 +00003041- Issue #2045: Fix an infinite recursion triggered when printing a
3042 subclass of collections.defaultdict, if its default_factory is set
3043 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003044
Christian Heimesf75dbef2008-02-08 00:11:31 +00003045- Fixed a minor memory leak in dictobject.c. The content of the free
3046 list was not freed on interpreter shutdown.
3047
Georg Brandl3ee81df2008-05-17 18:14:43 +00003048- Limit free list of method and builtin function objects to 256
3049 entries each.

3052 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003053 to compact the internal free lists of pre-allocted ints and floats.
3054
Georg Brandl3ee81df2008-05-17 18:14:43 +00003055- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3056 calls. Python expected the return type int but the fork familie
3057 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003058
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003071- Patch #1473257: generator objects gain a gi_code attribute. This is
3072 the same object as the func_code attribute of the function that
3073 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003074
Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- Issue #1920: "while 0" statements were completely removed by the
3076 compiler, even in the presence of an "else" clause, which is
3077 supposed to be run when the condition is false. Now the compiler
3078 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003079
Guido van Rossumeead05f2008-01-24 18:21:02 +00003080- A few crashers fixed: weakref_in_del.py (issue #1377858);
3081 loosing_dict_ref.py (issue #1303614, test67.py);
3082 borrowed_ref_[34].py (not in tracker).
3083
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003084- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003085 suppressed while an extension is loaded by calling SetErrorMode in
3086 dynload_win.c. The error is still reported properly.
3087
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003089 several extension methods and modules do not work without unicode
3090 support.
3091
Georg Brandl26543b12008-01-21 18:36:51 +00003092- Issue #1882: when compiling code from a string, encoding cookies in the
3093 second line of code were not always recognized correctly.
3094
Georg Brandl14404b62008-01-19 19:27:05 +00003095- Issue #1679: "0x" was taken as a valid integer literal.
3096
Georg Brandl6caad7d2008-01-26 14:19:22 +00003097- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003098 added.
3099
Christian Heimesc94e2b52008-01-14 04:13:37 +00003100- sys.float_info / PyFloat_GetInfo: The floating point information
3101 object was converted from a dict to a specialized structseq object.
3102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Patch #1816: Added sys.flags structseq. It exposes the status of
3104 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003105
Georg Brandl3ee81df2008-05-17 18:14:43 +00003106- Objects/structseq.c: Implemented new structseq representation. The
3107 patch makes structseqs (e.g. the return value of os.stat) more
3108 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Patch #1700288: added a type attribute cache that caches method
3111 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003112
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003113- Bug #1776: __import__() no longer accepts filenames on any platform.
3114 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003115
Georg Brandlaed6c662008-01-07 17:25:53 +00003116- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3117
Georg Brandl3ee81df2008-05-17 18:14:43 +00003118- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3119 envvar and sys.dont_write_bytecode attribute. All these can be set
3120 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003121
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122- Improve some exception messages when Windows fails to load an
3123 extension module. Now we get for example '%1 is not a valid Win32
3124 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003125
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003128- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3129 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003130
Christian Heimes0a8143f2007-12-18 23:22:54 +00003131- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003132 and INF. float("nan"), float("inf") and float("-inf") now work on
3133 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003134
Georg Brandl3ee81df2008-05-17 18:14:43 +00003135- Compiler now generates simpler and faster code for dictionary
3136 literals. The oparg for BUILD_MAP now indicates an estimated
3137 dictionary size. There is a new opcode, STORE_MAP, for adding
3138 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003139
Georg Brandl3ee81df2008-05-17 18:14:43 +00003140- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003145- Issue #1538: Avoid copying string in split/rsplit if the split char
3146 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003147
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003148- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003149 SystemError.
3150
Nick Coghlanef01d822007-12-03 12:55:17 +00003151- PEP 366: Allow explicit relative imports when executing modules

3156 running, and if the deallocation of its frames somehow calls the
3157 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003158

3163
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164- Issue #1460: The utf-7 incremental decoder did not accept truncated
3165 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003166
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Patch #1739468: Directories and zipfiles containing a __main__.py
3168 file can now be directly executed by passing their name to the
3169 interpreter. The directory/zipfile is automatically inserted as the
3170 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003171
Georg Brandl3ee81df2008-05-17 18:14:43 +00003172- Issue #1265: Fix a problem with sys.settrace, if the tracing
3173 function uses a generator expression when at the same time the
3174 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003175
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003176- sets and frozensets now have an isdisjoint() method.
3177
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003178- optimize the performance of builtin.sum().
3179
Neal Norwitz44f326e2007-10-05 05:29:17 +00003180- Fix warnings found by the new version of the Coverity checker.
3181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182- The enumerate() builtin function is no longer bounded to sequences
3183 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3184 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003185
Georg Brandl3ee81df2008-05-17 18:14:43 +00003186- Issue #1686386: Tuple's tp_repr did not take into account the
3187 possibility of having a self-referential tuple, which is possible
3188 from C code. Nor did object's tp_str consider that a type's tp_str
3189 could do something that could lead to an inifinite recursion.
3190 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3191 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003192
Georg Brandl3ee81df2008-05-17 18:14:43 +00003193- Issue #1164: It was possible to trigger deadlock when using the
3194 'print' statement to write to a file since the GIL was not released
3195 as needed. Now PyObject_Print() does the right thing along with
3196 various tp_print implementations of the built-in types and those in
3197 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003198
Georg Brandl3ee81df2008-05-17 18:14:43 +00003199- Issue #1147: Exceptions were directly allowing string exceptions in
3200 their throw() method even though string exceptions no longer
3201 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003202
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Issue #1096: Prevent a segfault from getting the repr of a very
3204 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003205
Brett Cannon1e534b52007-09-07 04:18:30 +00003206- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003207 PyObject_Call() never calling back out to Python code to trigger
3208 recursion depth updates/checks. Required the creation of a static
3209 RuntimeError instance in case normalizing an exception put the
3210 recursion check value past its limit. Fixes crashers
3211 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003212
Georg Brandl3ee81df2008-05-17 18:14:43 +00003213- Patch #1031213: Decode source line in SyntaxErrors back to its

3217 with %G.
3218
Georg Brandl3ee81df2008-05-17 18:14:43 +00003219- Prevent expandtabs() on string and unicode objects from causing a
3220 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003226- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003227 __*__ attributes. (Some already existed, e.g., __doc__ and
3228 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003229
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003230- Add -3 option to the interpreter to warn about features that are
3231 deprecated and will be changed/removed in Python 3.0.
3232
Georg Brandl2134e752007-05-21 20:34:16 +00003233- Patch #1686487: you can now pass any mapping after '**' in function
3234 calls.
3235
Collin Winter62903052007-05-18 23:11:24 +00003236- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237 "except E as target:". This is to provide forwards compatibility
3238 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003239
Brett Cannon229cee22007-05-05 01:34:02 +00003240- Deprecate BaseException.message as per PEP 352.
3241
Georg Brandl3ee81df2008-05-17 18:14:43 +00003242- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003243 inherited from a builtin base.
3244
Vinay Sajip8549ce32007-05-06 17:53:37 +00003245- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003246 setting a plain string, ie don't expand to single letter identifiers.
3247
Raymond Hettinger13936692007-04-11 18:40:58 +00003248- Request #1191699: Slices can now be pickled.
3249
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003250- Request #1193128: str.translate() now allows a None argument for
3251 translations that only remove characters without re-mapping the
3252 remaining characters.
3253
Georg Brandl5cb76c12007-03-21 09:00:39 +00003254- Patch #1682205: a TypeError while unpacking an iterable is no longer
3255 masked by a generic one with the message "unpack non-sequence".
3256
Neal Norwitzaa754b72007-03-21 06:39:48 +00003257- Remove unused file Python/fmod.c.
3258
Guido van Rossum143b5642007-03-23 04:58:42 +00003259- Bug #1683368: The object.__init__() and object.__new__() methods are
3260 now stricter in rejecting excess arguments. The only time when
3261 either allows excess arguments is when it is not overridden and the
3262 other one is. For backwards compatibility, when both are
3263 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003264 warning later). Also, type.__init__() insists on the same signature
3265 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003266
Georg Brandl3ee81df2008-05-17 18:14:43 +00003267- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3268 object to complex using its __complex__() method before falling back
3269 to the __float__() method. Therefore, the functions in the cmath
3270 module now can operate on objects that define a __complex__()
3271 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003272
Georg Brandl3ee81df2008-05-17 18:14:43 +00003273- Patch #1623563: allow __class__ assignment for classes with
3274 __slots__. The old and the new class are still required to have the
3275 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003276
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003280- Patch #1462488: Python no longer segfaults when
3281 ``object.__reduce_ex__()`` is called with an object that is faking
3282 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003287- Patch #1444529: the builtin compile() now accepts keyword arguments.
3288
Georg Brandl7b9c5552007-03-12 14:30:05 +00003289- Bug #1678647: write a newline after printing an exception in any
3290 case, even when converting the value to a string failed.
3291
Georg Brandl871f1bc2007-03-12 13:17:36 +00003292- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003293 its argument, if it exists. If not, it will work like before. This
3294 allows customizing the output of dir() in the presence of a
3295 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003296
Collin Winter276887b2007-03-12 16:11:39 +00003297- Patch #922167: Python no longer segfaults when faced with infinitely
3298 self-recursive reload() calls (as reported by bug #742342).
3299
Georg Brandl3ee81df2008-05-17 18:14:43 +00003300- Patch #1675981: remove unreachable code from ``type.__new__()``
3301 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003303- Patch #1491866: change the complex() constructor to allow
3304 parthensized forms. This means complex(repr(x)) now works instead of
3305 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003306
Georg Brandlaa2321b2007-03-07 00:40:28 +00003307- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003308 makes the filenames the warning module prints much more sensible
3309 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003310

3817
Facundo Batistad918a652007-04-24 13:54:38 +00003818- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003819 the client's request was successfully received, understood, and
3820 accepted. Now in these cases no error is raised in urllib (issue
3821 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003822

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003829- Added a timeout parameter to the constructor of other protocols
3830 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3831 work started with create_connection() and timeout in httplib, and
3832 closes patch #723312.
3833
Vinay Sajip8549ce32007-05-06 17:53:37 +00003834- Patch #1676823: Added create_connection() to socket.py, which may be
3835 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003836 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003837
Martin v. Löwis0af33882007-03-23 13:27:15 +00003838- Bug #978833: Revert r50844, as it broke _socketobject.dup.

3858
Georg Brandlf66b6032007-03-14 08:27:52 +00003859- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860 AttributeError instead of an IOError when the server's response
3861 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003862
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863- Patch #957650: "%var%" environment variable references are now
3864 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00003866
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867- Patch #1429539: pdb now correctly initializes the __main__ module
3868 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003869 correctly now.
3870
Georg Brandlbad6f192007-03-13 21:32:56 +00003871- The nonobvious commands.getstatus() function is now deprecated.

3877
Georg Brandl3ee81df2008-05-17 18:14:43 +00003878- Patch #1530482: add pydoc.render_doc() which returns the
3879 documentation for a thing instead of paging it to stdout, which
3880 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003881
Georg Brandl3ee81df2008-05-17 18:14:43 +00003882- Patch #1533909: the timeit module now accepts callables in addition

3888 parameter which can be set to False to prevent the default
3889 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00003891- Patch #1581073: add a flag to textwrap that prevents the dropping of
3892 whitespace while wrapping.
3893
Georg Brandl92a6bae2007-03-13 17:43:32 +00003894- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003895 are set for invalid interpolation sequences that would lead to
3896 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003897

Georg Brandl3ee81df2008-05-17 18:14:43 +00003912 field names in its exception message if you try to write a record
3913 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003931

3939 returned string up to the first NUL character.
3940

3950
Georg Brandl3ee81df2008-05-17 18:14:43 +00003951- unittest now verifies more of its assumptions. In particular,
3952 TestCase and TestSuite subclasses (not instances) are no longer
3953 accepted in TestSuite.addTest(). This should cause no
3954 incompatibility since it never made sense with ordinary subclasses
3955 -- the failure just occurred later, with a more cumbersome
3956 exception.

3965 given a unicode argument and os.listdir() returns unicode filenames.
3966
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967- Patch #1673619: setup.py identifies extension modules it doesn't

3969 build.

4327 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4328 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004345 time so that opening a database previously created with the DB_DUP
4346 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4347 opens. Specifically: dictionary assignment to a DB object will
4348 replace all values for a given key when the database allows
4349 duplicate values. DB users should use DB.put(k, v) when they want
4350 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004351

4357 characters with ASCII value less than 32. Also, it correctly quotes
4358 dots only if they occur on a single line, as opposed to the previous
4359 behavior of quoting dots if they are the second character of any
4360 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004361
