130
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000131- Issue #5829: complex("1e500") no longer raises OverflowError. This

144 rejected; (2) parsing of strings representing infinities and nans
145 was locale aware; and (3) the interpretation of fromhex('-nan')
146 didn't match that of float('-nan').
147
Eric Smitha985a3a2009-05-05 18:26:08 +0000148- Issue #5920: For float.__format__, change the behavior with the
149 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
150 to be like 'g' but with at least one decimal point and with a
151 default precision of 12. Previously, the behavior the same but with
152 a default precision of 6. This more closely matches str(), and
153 reduces surprises when adding alignment flags to the empty
154 presentation type. This also affects the new complex.__format__ in
155 the same way.
156
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000157- Issue #5890: in subclasses of 'property' the __doc__ attribute was

Mark Dickinson95bc9802009-04-24 12:46:53 +0000181- Issue #5816: complex(repr(z)) now recovers z exactly, even when
182 z involves nans, infs or negative zeros.
183
Eric Smithaca19e62009-04-22 13:29:05 +0000184- Implement PEP 378, Format Specifier for Thousands Separator, for
185 floats, ints, and longs.
186
187- Issue #5515: 'n' formatting for ints, longs, and floats handles
188 leading zero formatting poorly.
189
190- Issue #5772: For float.__format__, don't add a trailing ".0" if
191 we're using no type code and we have an exponent.

198
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000199- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000200 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000201
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000202- Issue #5759: float() didn't call __float__ on str subclasses.

220 untrackable objects are not tracked by the garbage collector. This can
221 reduce the size of collections and therefore the garbage collection overhead
222 on long-running programs, depending on their particular use of datatypes.
223
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000224- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
225 improve its performance. Long divisions and remainder operations

229 2**15 for the internal representation of integers, for performance
230 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
231 --enable-big-digits option to configure, which overrides the
232 default. Add sys.long_info structseq to provide information about
233 the internal format.
234

241
Eric Smith6f42edb2009-03-14 11:57:26 +0000242- Issue #5237: Allow auto-numbered fields in str.format(). For

244
Brett Cannon6c4cff02009-03-11 04:51:06 +0000245- Issue #3652: Make the 'line' argument for warnings.showwarning() a
246 requirement. Means the DeprecationWarning from Python 2.6 can go away.

256 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
257 on a 64-bit system.
258
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000259- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

266
Georg Brandl29c6a282009-04-05 20:23:13 +0000267- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000268 were suppressing all exceptions. These include list(), filter(), map(),
269 zip(), and bytearray().
270

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

307 file with `str' filename on Windows.
308
Antoine Pitrouaa687902009-01-01 14:11:22 +0000309- Issue #3680: Reference cycles created through a dict, set or deque iterator

311
Nick Coghlan180e4002008-12-30 01:18:48 +0000312- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
313 where the tp_hash and tp_dict slots are both NULL.
314
Benjamin Peterson7af65562008-12-29 17:56:58 +0000315- Issue #4764: With io.open, IOError.filename is set when trying to open a
316 directory on POSIX systems.
317
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000318- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

320
Georg Brandl6425a2f2008-12-28 11:54:53 +0000321- Issue #4759: None is now allowed as the first argument of
322 bytearray.translate(). It was always allowed for bytes.translate().
323
Skip Montanarof205c132008-12-23 03:30:15 +0000324- Added test case to ensure attempts to read from a file opened for writing
325 fail.
326
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000327- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

337 context manager returns a value that cannot be converted to a bool.
338
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000339- Issue #4597: Fixed several opcodes that weren't always propagating
340 exceptions.
341
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000342- Issue #4445: Replace "sizeof(PyStringObject)" with
343 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
344 str instances. On a typical machine this saves 3 bytes of memory
345 (on average) per string allocation.
346
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000347- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
348 interpreter to abort ("Fatal Python error: Could not reset the stack!")
349 instead of throwing a MemoryError.
350
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000351- Issue #3689: The list reversed iterator now supports __length_hint__

355 module couldn't be imported and \N escapes were present.
356
Vinay Sajip213faca2008-12-03 23:22:58 +0000357- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000358 method on file objects with closefd=False. The file descriptor is still
359 kept open but the file object behaves like a closed file. The ``FileIO``
360 object also got a new readonly attribute ``closefd``.
361
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000362- Issue #4348: Some bytearray methods returned that didn't cause any change to

375 method does not return iterators for the 4th and 5th items.
376
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000377- Issue #4209: Enabling unicode_literals and the print_function in the same
378 __future__ import didn't work.
379
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000380- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000381 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000382
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000383- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
384 returned a path longer than MAX_PATH. (But It's doubtful this code path is
385 really executed because I cannot move to such directory on win2k)
386
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000387- Issue #4069: When set.remove(element) is used with a set element, the element
388 is temporarily replaced with an equivalent frozenset. But the eventual
389 KeyError would always report the empty frozenset([]) as the missing key. Now
390 it correctly refers to the initial element.
391
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000392- Issue #4509: Various issues surrounding resize of bytearray objects to

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000407- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
408 returned them on 64bit platforms.
409
Walter Dörwalded960ac2009-05-03 22:36:33 +0000410- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
411 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
412 step. This avoids problems with counting UTF-8 bytes that ignores the effect
413 of using the replace error handler in PyUnicode_DecodeUTF8().
414
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000415- Issue #3739: The unicode-internal encoder now reports the number of characters
416 consumed like any other encoder (instead of the number of bytes).

1636
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001637- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1638 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1639 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1640 ``printf`` function, whereas PyString_FromFormat has an independent
1641 implementation and uses "%zd" on all platforms for size_t values.
1642 This makes a difference on win64, where ``printf`` needs "%Id" to display
1643 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001660 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001662- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001663 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1664 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1665 when given a tuple of classes as second argument, were looking up
1666 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1667 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001806What's New in Python 2.6 beta 3?
1807================================
1808
Barry Warsaw07a4a382008-08-21 01:15:08 +00001809*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001810
1811Core and Builtins
1812-----------------
1813
Guido van Rossumf8402962008-08-20 15:01:50 +00001814- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1815 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1816 extensions do not automatically benefit from the class attribute
1817 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1818 to their tp_flags field if they care. This is a backwards
1819 compatibility feature; in 3.0, all types will use the cache by
1820 default.
1821
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001822- Keyword arguments can now follow starred arguments. (``f(a, *args,
1823 keyword=23)`` is now valid syntax.)
1824
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001825- ctypes function pointers that are COM methods have a boolean True
1826 value again.
1827
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001828- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1829 by denying s# to parse objects that have a releasebuffer procedure,
1830 and introducing s*.
1831
Georg Brandl1e13ea92008-08-11 09:07:59 +00001832- Issue #3537: Fix an assertion failure when an empty but presized dict
1833 object was stored in the freelist.
1834
Mark Dickinsonb6467572008-08-04 21:30:09 +00001835- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1836 ValueError consistently across platforms.
1837
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001838- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1839 (64bit Unix, for example), unichr() would truncate its argument and return
1840 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1841
Neal Norwitze7d8be82008-07-31 17:17:14 +00001842- Apply security patches from Apple.
1843
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001844- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1845 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1846
Antoine Pitrou92f82162008-07-25 22:22:08 +00001847- Issue #1819: function calls with several named parameters are now on
1848 average 35% faster (as measured by pybench).
1849
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001850- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1851 the python debugger steps into a class statement: the free variables (local
1852 variables defined in an outer scope) would be deleted from the outer scope.
1853
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001854- Issue #2620: Overflow checking when allocating or reallocating memory
1855 was not always being done properly in some python types and extension
1856 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1857 all been updated to perform better checks and places in the code that
1858 would previously leak memory on the error path when such an allocation
1859 failed have been fixed.

1862-------
1863
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001864- Issue #3612: Added some missing basic types in ctypes.wintypes.
1865
Benjamin Petersone977ad42008-08-20 01:42:01 +00001866- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1867 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1868
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001869- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1870 version reported by these tools does not necessarily follow the python
1871 version numbering scheme, so the module is less strict when parsing it.
1872
Nick Coghlanf70385a2008-08-18 12:42:46 +00001873- Issue #2235: Added Py3k warnings for types which will become unhashable
1874 under the stricter __hash__ inheritance rules in 3.0. Several types
1875 which did not meet the rules for hash invariants and were already
1876 unhashable in 3.0 have now been explicitly flagged as unhashable in
1877 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1878 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1879
Brett Cannon88f801d2008-08-18 00:46:22 +00001880- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1881 imported into the module but exposed as part of the module's API.
1882
Brett Cannon7b96f072008-08-18 00:41:11 +00001883- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1884
Brett Cannon46225e72008-08-18 00:36:52 +00001885- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001887- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1888
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001889- Issue #3575: Incremental decoder's decode function now takes bytearray
1890 by using 's*' instead of 't#'.
1891
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001892- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001893 fails unicode conversion on 2nd parameter. (windows only)
1894
Facundo Batista94f243a2008-08-17 03:38:39 +00001895- Issue 2464. urllib2 now supports a malformation in the URL received
1896 in a redirect.
1897
Brett Cannonabe423e2008-08-16 21:47:07 +00001898- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001899 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001900
Facundo Batistaeb90b782008-08-16 14:44:07 +00001901- Issue #2776: fixed small issue when handling an URL with double slash
1902 after a 302 response in the case of not going through a proxy.
1903
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001904- Issue #2676: in the email package, content-type parsing was hanging on
1905 pathological input because of quadratic or exponential behaviour of a
1906 regular expression.
1907
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001908- Issue #3476: binary buffered reading through the new "io" library is now
1909 thread-safe.
1910
Brett Cannonbf3157b2008-08-14 05:00:03 +00001911- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1912 since mimetools itself is deprecated. Because modules are cached, all
1913 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1914
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001915- Issue #3134: shutil referenced undefined WindowsError symbol.
1916
Robert Schuppenies14646332008-08-10 11:01:53 +00001917- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1918 menu entries were not deleted.
1919
Brett Cannon83e81842008-08-09 23:30:55 +00001920- Copied the implementation of reduce() to _functools.reduce() to have a
1921 version that did not raise a DeprecationWarning under -3.
1922
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001923- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1924 a MemoryError rather than silently stop the iteration.
1925
Guido van Rossum59ce9012008-08-09 14:55:34 +00001926- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1927 to _sre.compile() will now be rejected. This should not affect anybody
1928 since the re.compile() function never generates invalid re-bytecode.
1929
Skip Montanaroa032bf42008-08-08 22:52:51 +00001930- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1931 upon first access it can be automatically initialized from the csv file if
1932 it wasn't initialized during instantiation.
1933
Brett Cannon3aa2a492008-08-06 22:28:09 +00001934- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1935 the reload() built-in has been removed.
1936
Brett Cannon7e30b672008-08-04 21:52:25 +00001937- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001938 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001949 asking for a specific length. This problem only affected files opened
1950 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001951

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001975- Issue #3394: zipfile.writestr sets external attributes when passed a
1976 file name rather than a ZipInfo instance, so files are extracted with
1977 mode 0600 rather than 000 under Unix.
1978
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001979- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1980 argument in python 2.5, this broke code that subclassed Popen to include its

2006-----------------
2007
Georg Brandl3e483f62008-07-16 22:57:41 +00002008- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2009 its methods now allow for items objects that can be converted to
2010 an integer using operator.index().
2011
Mark Dickinson64b7e502008-07-16 09:40:03 +00002012- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2013 produced a ValueError instead of giving the correct float.
2014
Eric Smitha5fa5a22008-07-16 00:11:49 +00002015- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2016 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2017
Mark Dickinson7103aa42008-07-15 19:08:33 +00002018- Issue #3008: the float type has a new instance method 'float.hex'
2019 and a new class method 'float.fromhex' to convert floating-point
2020 numbers to and from hexadecimal strings, respectively.
2021
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002022- Issue #2235: __hash__ is once again inherited by default. To allow
2023 collections.Hashable to remain meaningful in the presence of the
2024 default hash implementation (object.__hash__), it is now possible
2025 to explicit block inheritance of hash by setting __hash__=None at
2026 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2027 level.
2028
Nick Coghlanb028f502008-07-13 14:52:36 +00002029- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2030 the parent module cannot be found while performing an absolute import.
2031 This means that an incorrectly defined __package__ attribute will
2032 now only prevent relative imports in that module rather than causing
2033 all imports from that module to fail.
2034
Nick Coghlan14ff9942008-07-08 14:21:42 +00002035- Issue #2517: Allow unicode messages in Exceptions again by correctly

2044 threading.local: the first member set by a thread could be saved in
2045 another thread's dictionary.
2046
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002047- Issue #3004: Minor change to slice.indices(): the start and stop
2048 arguments are now treated identically, making the behaviour easier
2049 to describe and understand. For example, slice(None, -10,
2050 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2051 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2052 10, -1).
2053
Georg Brandl278fc502008-07-19 12:46:12 +00002054- Issue #3219: Calling a function with repeated keyword arguments,
2055 f(a=2, a=23), would not cause a syntax error. This was a regression
2056 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002057
Georg Brandl278fc502008-07-19 12:46:12 +00002058- Issue #2862: Make int and float freelist management consistent with
2059 other freelists. Changes their CompactFreeList apis into
2060 ClearFreeList apis and calls them via gc.collect().

2066 api functions without holding the GIL, which could lead to a fatal
2067 error when they failed.
2068
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002069- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002094- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2095 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002096 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002097 content-length. The problem had been corrected in the 2.4 branch, but never
2098 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002113- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2570 using the 'warning's machinery in such places as the parser where
2571 use of pure Python code is not possible. Both the ``showarning()``
2572 and ``formatwarning()`` gain an optional 'line' argument which is
2573 not called by default for backwards-compatibility reasons. Setting
2574 ``warnings.showwarning()`` to an implementation that lacks support
2575 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002638- Issue #2550: The approach used by client/server code for obtaining
2639 ports to listen on in network-oriented tests has been refined in an
2640 effort to facilitate running multiple instances of the entire
2641 regression test suite in parallel without issue.
2642 test_support.bind_port() has been fixed such that it will always
2643 return a unique port -- which wasn't always the case with the
2644 previous implementation, especially if socket options had been set
2645 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2646 new implementation of bind_port() will actually raise an exception
2647 if it is passed an AF_INET/SOCK_STREAM socket with either the
2648 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2649 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2650 the socket it's been passed. This currently only applies to
2651 Windows. This option prevents any other sockets from binding to the
2652 host/port we've bound to, thus removing the possibility of the
2653 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2654 when a second SOCK_STREAM socket binds and accepts to a host/port
2655 that's already been bound by another socket. The optional preferred
2656 port parameter to bind_port() has been removed. Under no
2657 circumstances should tests be hard coding ports!
2658
2659 test_support.find_unused_port() has also been introduced, which will
2660 pass a temporary socket object to bind_port() in order to obtain an
2661 unused port. The temporary socket object is then closed and
2662 deleted, and the port is returned. This method should only be used
2663 for obtaining an unused port in order to pass to an external program
2664 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2665 a parameter to a server-oriented class that doesn't give you direct
2666 access to the underlying socket used.
2667
2668 Finally, test_support.HOST has been introduced, which should be used
2669 for the host argument of any relevant socket calls (i.e. bind and
2670 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002671
2672 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002673 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002674 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2675 test_asynchat and test_socket_ssl.
2676
Georg Brandl3ee81df2008-05-17 18:14:43 +00002677 It is now possible for multiple instances of the regression test
2678 suite to run in parallel without issue.

2945-----------------
2946
Fred Drakea8ee94b2008-03-01 02:45:07 +00002947- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002948 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002950- Issue #2067: file.__exit__() now calls subclasses' close() method.
2951
2952- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002953
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002954- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002955 issue 215555 for a discussion.
2956
Eric Smitha73fbe72008-02-23 03:09:44 +00002957- Added the future_builtins module, which contains hex() and oct().
2958 These are the PEP 3127 version of these functions, designed to be
2959 compatible with the hex() and oct() builtins from Python 3.0. They
2960 differ slightly in their output formats from the existing, unchanged
2961 Python 2.6 builtins. The expected usage of the future_builtins
2962 module is:
2963 from future_builtins import hex, oct
2964
Eric Smith7ef40bf2008-02-20 23:34:22 +00002965- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2966 exponents for exponents with absolute value < 100. Follows C99
2967 standard. This is a change on Windows, which would use 3 digits.
2968 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2969 so that any alterations it does to the resulting string will be
2970 available in stringlib/formatter.h (for float.__format__).
2971
Eric Smith5a3c1352008-02-19 13:21:56 +00002972- Implemented PEP 3101, Advanced String Formatting. This adds a new
2973 builtin format(); a format() method for str and unicode; a
2974 __format__() method to object, str, unicode, int, long, float, and
2975 datetime; the class string.Formatter; and the C API
2976 PyObject_Format().
2977
Georg Brandl3ee81df2008-05-17 18:14:43 +00002978- Fixed several potential crashes, all caused by specially crafted
2979 __del__ methods exploiting objects in temporarily inconsistent
2980 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002981
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002982- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002983 prevent a possible crash: an Abstract Base Class would try to access
2984 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002985

Georg Brandl3ee81df2008-05-17 18:14:43 +00002989- Clear all free lists during a gc.collect() of the highest generation
2990 in order to allow pymalloc to free more arenas. Python may give back
2991 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002992
Georg Brandl3ee81df2008-05-17 18:14:43 +00002993- Issue #2045: Fix an infinite recursion triggered when printing a
2994 subclass of collections.defaultdict, if its default_factory is set
2995 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002996
Christian Heimesf75dbef2008-02-08 00:11:31 +00002997- Fixed a minor memory leak in dictobject.c. The content of the free
2998 list was not freed on interpreter shutdown.
2999
Georg Brandl3ee81df2008-05-17 18:14:43 +00003000- Limit free list of method and builtin function objects to 256
3001 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003002
Georg Brandl3ee81df2008-05-17 18:14:43 +00003003- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3004 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003005 to compact the internal free lists of pre-allocted ints and floats.
3006
Georg Brandl3ee81df2008-05-17 18:14:43 +00003007- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3008 calls. Python expected the return type int but the fork familie
3009 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003010
Georg Brandl3ee81df2008-05-17 18:14:43 +00003011- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3021 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003022
Georg Brandl3ee81df2008-05-17 18:14:43 +00003023- Patch #1473257: generator objects gain a gi_code attribute. This is
3024 the same object as the func_code attribute of the function that
3025 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003026
Georg Brandl3ee81df2008-05-17 18:14:43 +00003027- Issue #1920: "while 0" statements were completely removed by the
3028 compiler, even in the presence of an "else" clause, which is
3029 supposed to be run when the condition is false. Now the compiler
3030 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003031
Guido van Rossumeead05f2008-01-24 18:21:02 +00003032- A few crashers fixed: weakref_in_del.py (issue #1377858);
3033 loosing_dict_ref.py (issue #1303614, test67.py);
3034 borrowed_ref_[34].py (not in tracker).
3035
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003036- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003037 suppressed while an extension is loaded by calling SetErrorMode in

3039
Georg Brandl3ee81df2008-05-17 18:14:43 +00003040- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003041 several extension methods and modules do not work without unicode
3042 support.
3043
Georg Brandl26543b12008-01-21 18:36:51 +00003044- Issue #1882: when compiling code from a string, encoding cookies in the

3048
Georg Brandl6caad7d2008-01-26 14:19:22 +00003049- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003050 added.
3051
Christian Heimesc94e2b52008-01-14 04:13:37 +00003052- sys.float_info / PyFloat_GetInfo: The floating point information
3053 object was converted from a dict to a specialized structseq object.
3054
Georg Brandl3ee81df2008-05-17 18:14:43 +00003055- Patch #1816: Added sys.flags structseq. It exposes the status of
3056 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003057
Georg Brandl3ee81df2008-05-17 18:14:43 +00003058- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00003062- Patch #1700288: added a type attribute cache that caches method
3063 accesses, resulting in speedups in heavily object-oriented code.

3071 envvar and sys.dont_write_bytecode attribute. All these can be set
3072 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Improve some exception messages when Windows fails to load an
3075 extension module. Now we get for example '%1 is not a valid Win32
3076 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003083- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003084 and INF. float("nan"), float("inf") and float("-inf") now work on
3085 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Compiler now generates simpler and faster code for dictionary
3088 literals. The oparg for BUILD_MAP now indicates an estimated
3089 dictionary size. There is a new opcode, STORE_MAP, for adding
3090 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003119- Patch #1739468: Directories and zipfiles containing a __main__.py
3120 file can now be directly executed by passing their name to the
3121 interpreter. The directory/zipfile is automatically inserted as the
3122 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003124- Issue #1265: Fix a problem with sys.settrace, if the tracing
3125 function uses a generator expression when at the same time the
3126 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003127
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003128- sets and frozensets now have an isdisjoint() method.

3133
Georg Brandl3ee81df2008-05-17 18:14:43 +00003134- The enumerate() builtin function is no longer bounded to sequences
3135 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3136 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003137
Georg Brandl3ee81df2008-05-17 18:14:43 +00003138- Issue #1686386: Tuple's tp_repr did not take into account the
3139 possibility of having a self-referential tuple, which is possible
3140 from C code. Nor did object's tp_str consider that a type's tp_str
3141 could do something that could lead to an inifinite recursion.
3142 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3143 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003144
Georg Brandl3ee81df2008-05-17 18:14:43 +00003145- Issue #1164: It was possible to trigger deadlock when using the
3146 'print' statement to write to a file since the GIL was not released
3147 as needed. Now PyObject_Print() does the right thing along with
3148 various tp_print implementations of the built-in types and those in
3149 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003150
Georg Brandl3ee81df2008-05-17 18:14:43 +00003151- Issue #1147: Exceptions were directly allowing string exceptions in
3152 their throw() method even though string exceptions no longer
3153 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003154
Georg Brandl3ee81df2008-05-17 18:14:43 +00003155- Issue #1096: Prevent a segfault from getting the repr of a very
3156 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003157
Brett Cannon1e534b52007-09-07 04:18:30 +00003158- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159 PyObject_Call() never calling back out to Python code to trigger
3160 recursion depth updates/checks. Required the creation of a static
3161 RuntimeError instance in case normalizing an exception put the
3162 recursion check value past its limit. Fixes crashers
3163 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003164

Neal Norwitz0ac60192007-05-27 04:08:54 +00003178- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003179 __*__ attributes. (Some already existed, e.g., __doc__ and
3180 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003181
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003182- Add -3 option to the interpreter to warn about features that are
3183 deprecated and will be changed/removed in Python 3.0.
3184
Georg Brandl2134e752007-05-21 20:34:16 +00003185- Patch #1686487: you can now pass any mapping after '**' in function
3186 calls.
3187
Collin Winter62903052007-05-18 23:11:24 +00003188- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003189 "except E as target:". This is to provide forwards compatibility
3190 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003191
Brett Cannon229cee22007-05-05 01:34:02 +00003192- Deprecate BaseException.message as per PEP 352.
3193
Georg Brandl3ee81df2008-05-17 18:14:43 +00003194- Issue #1303614: don't expose object's __dict__ when the dict is

3196
Vinay Sajip8549ce32007-05-06 17:53:37 +00003197- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003198 setting a plain string, ie don't expand to single letter identifiers.
3199
Raymond Hettinger13936692007-04-11 18:40:58 +00003200- Request #1191699: Slices can now be pickled.
3201
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003202- Request #1193128: str.translate() now allows a None argument for
3203 translations that only remove characters without re-mapping the
3204 remaining characters.
3205
Georg Brandl5cb76c12007-03-21 09:00:39 +00003206- Patch #1682205: a TypeError while unpacking an iterable is no longer
3207 masked by a generic one with the message "unpack non-sequence".
3208
Neal Norwitzaa754b72007-03-21 06:39:48 +00003209- Remove unused file Python/fmod.c.
3210
Guido van Rossum143b5642007-03-23 04:58:42 +00003211- Bug #1683368: The object.__init__() and object.__new__() methods are
3212 now stricter in rejecting excess arguments. The only time when
3213 either allows excess arguments is when it is not overridden and the
3214 other one is. For backwards compatibility, when both are
3215 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003216 warning later). Also, type.__init__() insists on the same signature
3217 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003218
Georg Brandl3ee81df2008-05-17 18:14:43 +00003219- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3220 object to complex using its __complex__() method before falling back
3221 to the __float__() method. Therefore, the functions in the cmath
3222 module now can operate on objects that define a __complex__()
3223 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003224
Georg Brandl3ee81df2008-05-17 18:14:43 +00003225- Patch #1623563: allow __class__ assignment for classes with
3226 __slots__. The old and the new class are still required to have the
3227 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003228
Georg Brandl3ee81df2008-05-17 18:14:43 +00003229- Patch #1642547: Fix an error/crash when encountering syntax errors

3233 ``object.__reduce_ex__()`` is called with an object that is faking
3234 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003235
Georg Brandl3ee81df2008-05-17 18:14:43 +00003236- Patch #1680015: Don't modify __slots__ tuple if it contains an

3240
Georg Brandl7b9c5552007-03-12 14:30:05 +00003241- Bug #1678647: write a newline after printing an exception in any
3242 case, even when converting the value to a string failed.
3243
Georg Brandl871f1bc2007-03-12 13:17:36 +00003244- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245 its argument, if it exists. If not, it will work like before. This
3246 allows customizing the output of dir() in the presence of a
3247 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003248
Collin Winter276887b2007-03-12 16:11:39 +00003249- Patch #922167: Python no longer segfaults when faced with infinitely
3250 self-recursive reload() calls (as reported by bug #742342).
3251
Georg Brandl3ee81df2008-05-17 18:14:43 +00003252- Patch #1675981: remove unreachable code from ``type.__new__()``

3256 parthensized forms. This means complex(repr(x)) now works instead of
3257 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003258
Georg Brandlaa2321b2007-03-07 00:40:28 +00003259- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260 makes the filenames the warning module prints much more sensible
3261 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003262
Georg Brandl49aafc92007-03-07 00:34:46 +00003263- Variant of patch #697613: don't exit the interpreter on a SystemExit
3264 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003265 variable is given, but break into the interactive interpreter just
3266 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003274- Patch #1674228: when assigning a slice (old-style), check for the
3275 sq_ass_slice instead of the sq_slice slot.
3276
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- When printing an unraisable error, don't print exceptions. before
3278 the name. This duplicates the behavior whening normally printing
3279 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003812 AttributeError instead of an IOError when the server's response
3813 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003814

Georg Brandl3ee81df2008-05-17 18:14:43 +00003819- Patch #1429539: pdb now correctly initializes the __main__ module
3820 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003821 correctly now.
3822

3829
Georg Brandl3ee81df2008-05-17 18:14:43 +00003830- Patch #1530482: add pydoc.render_doc() which returns the

3845
Georg Brandl92a6bae2007-03-13 17:43:32 +00003846- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847 are set for invalid interpolation sequences that would lead to
3848 errors on reading back those values.

3891 returned string up to the first NUL character.

3902
Georg Brandl3ee81df2008-05-17 18:14:43 +00003903- unittest now verifies more of its assumptions. In particular,
3904 TestCase and TestSuite subclasses (not instances) are no longer
3905 accepted in TestSuite.addTest(). This should cause no
3906 incompatibility since it never made sense with ordinary subclasses
3907 -- the failure just occurred later, with a more cumbersome
3908 exception.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004296- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004297 time so that opening a database previously created with the DB_DUP
4298 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4299 opens. Specifically: dictionary assignment to a DB object will
4300 replace all values for a given key when the database allows
4301 duplicate values. DB users should use DB.put(k, v) when they want
4302 to store duplicates; not DB[k] = v.

4309 characters with ASCII value less than 32. Also, it correctly quotes
4310 dots only if they occur on a single line, as opposed to the previous
4311 behavior of quoting dots if they are the second character of any
4312 line.

4658 of w# format code incorrectly truncated the length to an int, even
4659 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4660 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004690- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4691 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
