131 statement and correctly lookup the __enter__ and __exit__ special methods.
132
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000133- Issue #5829: complex("1e500") no longer raises OverflowError. This

146 rejected; (2) parsing of strings representing infinities and nans
147 was locale aware; and (3) the interpretation of fromhex('-nan')
148 didn't match that of float('-nan').
149
Eric Smitha985a3a2009-05-05 18:26:08 +0000150- Issue #5920: For float.__format__, change the behavior with the
151 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
152 to be like 'g' but with at least one decimal point and with a
153 default precision of 12. Previously, the behavior the same but with
154 a default precision of 6. This more closely matches str(), and
155 reduces surprises when adding alignment flags to the empty
156 presentation type. This also affects the new complex.__format__ in
157 the same way.
158
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000159- Issue #5890: in subclasses of 'property' the __doc__ attribute was

168
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000169- Issue #5864: Fix empty format code formatting for floats so that it

177
Eric Smith068f0652009-04-25 21:40:15 +0000178- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with

182
Mark Dickinson95bc9802009-04-24 12:46:53 +0000183- Issue #5816: complex(repr(z)) now recovers z exactly, even when
184 z involves nans, infs or negative zeros.
185
Eric Smithaca19e62009-04-22 13:29:05 +0000186- Implement PEP 378, Format Specifier for Thousands Separator, for
187 floats, ints, and longs.
188
189- Issue #5515: 'n' formatting for ints, longs, and floats handles
190 leading zero formatting poorly.
191
192- Issue #5772: For float.__format__, don't add a trailing ".0" if
193 we're using no type code and we have an exponent.
194

200
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000201- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000202 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000203
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000204- Issue #5759: float() didn't call __float__ on str subclasses.

222 untrackable objects are not tracked by the garbage collector. This can
223 reduce the size of collections and therefore the garbage collection overhead
224 on long-running programs, depending on their particular use of datatypes.
225
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000226- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
227 improve its performance. Long divisions and remainder operations

229
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000230- Issue #4258: Make it possible to use base 2**30 instead of base
231 2**15 for the internal representation of integers, for performance
232 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
233 --enable-big-digits option to configure, which overrides the
234 default. Add sys.long_info structseq to provide information about
235 the internal format.
236
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000237- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
238 result traceback.__members__ no longer exists.)
239
Mark Dickinson6b265f12009-03-18 16:07:26 +0000240- Issue #4474: PyUnicode_FromWideChar now converts characters outside
241 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

243
Eric Smith6f42edb2009-03-14 11:57:26 +0000244- Issue #5237: Allow auto-numbered fields in str.format(). For
245 example: '{} {}'.format(1, 2) == '1 2'.
246
Brett Cannon6c4cff02009-03-11 04:51:06 +0000247- Issue #3652: Make the 'line' argument for warnings.showwarning() a
248 requirement. Means the DeprecationWarning from Python 2.6 can go away.

258 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
259 on a 64-bit system.
260
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000261- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

268
Georg Brandl29c6a282009-04-05 20:23:13 +0000269- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000270 were suppressing all exceptions. These include list(), filter(), map(),
271 zip(), and bytearray().
272

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000300- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
301 an existing .py counterpart, override the co_filename attributes of all
302 code objects if the original filename is obsolete (which can happen if the
303 file has been renamed, moved, or if it is accessed through different paths).
304 Patch by Ziga Seilnacht and Jean-Paul Calderone.

310
Antoine Pitrouaa687902009-01-01 14:11:22 +0000311- Issue #3680: Reference cycles created through a dict, set or deque iterator

Nick Coghlan180e4002008-12-30 01:18:48 +0000314- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
315 where the tp_hash and tp_dict slots are both NULL.
316
Benjamin Peterson7af65562008-12-29 17:56:58 +0000317- Issue #4764: With io.open, IOError.filename is set when trying to open a
318 directory on POSIX systems.
319
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000320- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

324 bytearray.translate(). It was always allowed for bytes.translate().
325
Skip Montanarof205c132008-12-23 03:30:15 +0000326- Added test case to ensure attempts to read from a file opened for writing
327 fail.
328
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000329- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

342 exceptions.
343
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000344- Issue #4445: Replace "sizeof(PyStringObject)" with
345 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
346 str instances. On a typical machine this saves 3 bytes of memory
347 (on average) per string allocation.
348
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000349- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
350 interpreter to abort ("Fatal Python error: Could not reset the stack!")
351 instead of throwing a MemoryError.
352
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000353- Issue #3689: The list reversed iterator now supports __length_hint__

358
Vinay Sajip213faca2008-12-03 23:22:58 +0000359- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000360 method on file objects with closefd=False. The file descriptor is still
361 kept open but the file object behaves like a closed file. The ``FileIO``
362 object also got a new readonly attribute ``closefd``.
363
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000364- Issue #4348: Some bytearray methods returned that didn't cause any change to

377 method does not return iterators for the 4th and 5th items.
378
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000379- Issue #4209: Enabling unicode_literals and the print_function in the same
380 __future__ import didn't work.
381
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000382- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000383 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000384
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000385- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
386 returned a path longer than MAX_PATH. (But It's doubtful this code path is
387 really executed because I cannot move to such directory on win2k)
388
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000389- Issue #4069: When set.remove(element) is used with a set element, the element
390 is temporarily replaced with an equivalent frozenset. But the eventual
391 KeyError would always report the empty frozenset([]) as the missing key. Now
392 it correctly refers to the initial element.
393
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000394- Issue #4509: Various issues surrounding resize of bytearray objects to

410 returned them on 64bit platforms.
411
Walter Dörwalded960ac2009-05-03 22:36:33 +0000412- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
413 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
414 step. This avoids problems with counting UTF-8 bytes that ignores the effect
415 of using the replace error handler in PyUnicode_DecodeUTF8().
416
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000417- Issue #3739: The unicode-internal encoder now reports the number of characters

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001639- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1640 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1641 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1642 ``printf`` function, whereas PyString_FromFormat has an independent
1643 implementation and uses "%zd" on all platforms for size_t values.
1644 This makes a difference on win64, where ``printf`` needs "%Id" to display
1645 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001662 was correctly parsed but parsing of subsequent arguments failed.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001665 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1666 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1667 when given a tuple of classes as second argument, were looking up
1668 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1669 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001808What's New in Python 2.6 beta 3?
1809================================
1810
Barry Warsaw07a4a382008-08-21 01:15:08 +00001811*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001812
1813Core and Builtins
1814-----------------
1815
Guido van Rossumf8402962008-08-20 15:01:50 +00001816- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1817 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1818 extensions do not automatically benefit from the class attribute
1819 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1820 to their tp_flags field if they care. This is a backwards
1821 compatibility feature; in 3.0, all types will use the cache by
1822 default.
1823
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001824- Keyword arguments can now follow starred arguments. (``f(a, *args,
1825 keyword=23)`` is now valid syntax.)
1826
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001827- ctypes function pointers that are COM methods have a boolean True
1828 value again.
1829
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001830- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1831 by denying s# to parse objects that have a releasebuffer procedure,
1832 and introducing s*.
1833
Georg Brandl1e13ea92008-08-11 09:07:59 +00001834- Issue #3537: Fix an assertion failure when an empty but presized dict
1835 object was stored in the freelist.
1836
Mark Dickinsonb6467572008-08-04 21:30:09 +00001837- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1838 ValueError consistently across platforms.
1839
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001840- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1841 (64bit Unix, for example), unichr() would truncate its argument and return
1842 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1843
Neal Norwitze7d8be82008-07-31 17:17:14 +00001844- Apply security patches from Apple.
1845
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001846- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1847 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1848
Antoine Pitrou92f82162008-07-25 22:22:08 +00001849- Issue #1819: function calls with several named parameters are now on
1850 average 35% faster (as measured by pybench).
1851
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001852- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1853 the python debugger steps into a class statement: the free variables (local
1854 variables defined in an outer scope) would be deleted from the outer scope.
1855
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001856- Issue #2620: Overflow checking when allocating or reallocating memory
1857 was not always being done properly in some python types and extension
1858 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1859 all been updated to perform better checks and places in the code that
1860 would previously leak memory on the error path when such an allocation
1861 failed have been fixed.

1864-------
1865
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001866- Issue #3612: Added some missing basic types in ctypes.wintypes.
1867
Benjamin Petersone977ad42008-08-20 01:42:01 +00001868- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1869 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1870
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001871- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1872 version reported by these tools does not necessarily follow the python
1873 version numbering scheme, so the module is less strict when parsing it.
1874
Nick Coghlanf70385a2008-08-18 12:42:46 +00001875- Issue #2235: Added Py3k warnings for types which will become unhashable
1876 under the stricter __hash__ inheritance rules in 3.0. Several types
1877 which did not meet the rules for hash invariants and were already
1878 unhashable in 3.0 have now been explicitly flagged as unhashable in
1879 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1880 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1881
Brett Cannon88f801d2008-08-18 00:46:22 +00001882- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1883 imported into the module but exposed as part of the module's API.
1884
Brett Cannon7b96f072008-08-18 00:41:11 +00001885- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1886
Brett Cannon46225e72008-08-18 00:36:52 +00001887- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1888
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001889- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1890
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001891- Issue #3575: Incremental decoder's decode function now takes bytearray
1892 by using 's*' instead of 't#'.
1893
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001894- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001895 fails unicode conversion on 2nd parameter. (windows only)
1896
Facundo Batista94f243a2008-08-17 03:38:39 +00001897- Issue 2464. urllib2 now supports a malformation in the URL received
1898 in a redirect.
1899
Brett Cannonabe423e2008-08-16 21:47:07 +00001900- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001901 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001902
Facundo Batistaeb90b782008-08-16 14:44:07 +00001903- Issue #2776: fixed small issue when handling an URL with double slash
1904 after a 302 response in the case of not going through a proxy.
1905
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001906- Issue #2676: in the email package, content-type parsing was hanging on
1907 pathological input because of quadratic or exponential behaviour of a
1908 regular expression.
1909
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001910- Issue #3476: binary buffered reading through the new "io" library is now
1911 thread-safe.
1912
Brett Cannonbf3157b2008-08-14 05:00:03 +00001913- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1914 since mimetools itself is deprecated. Because modules are cached, all
1915 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1916
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001917- Issue #3134: shutil referenced undefined WindowsError symbol.
1918
Robert Schuppenies14646332008-08-10 11:01:53 +00001919- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1920 menu entries were not deleted.
1921
Brett Cannon83e81842008-08-09 23:30:55 +00001922- Copied the implementation of reduce() to _functools.reduce() to have a
1923 version that did not raise a DeprecationWarning under -3.
1924
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001925- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1926 a MemoryError rather than silently stop the iteration.
1927
Guido van Rossum59ce9012008-08-09 14:55:34 +00001928- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1929 to _sre.compile() will now be rejected. This should not affect anybody
1930 since the re.compile() function never generates invalid re-bytecode.
1931
Skip Montanaroa032bf42008-08-08 22:52:51 +00001932- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1933 upon first access it can be automatically initialized from the csv file if
1934 it wasn't initialized during instantiation.
1935
Brett Cannon3aa2a492008-08-06 22:28:09 +00001936- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1937 the reload() built-in has been removed.
1938
Brett Cannon7e30b672008-08-04 21:52:25 +00001939- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001940 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001951 asking for a specific length. This problem only affected files opened
1952 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001953

1978 file name rather than a ZipInfo instance, so files are extracted with
1979 mode 0600 rather than 000 under Unix.
1980
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001981- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1982 argument in python 2.5, this broke code that subclassed Popen to include its
1983 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2008-----------------
2009
Georg Brandl3e483f62008-07-16 22:57:41 +00002010- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2011 its methods now allow for items objects that can be converted to
2012 an integer using operator.index().
2013
Mark Dickinson64b7e502008-07-16 09:40:03 +00002014- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2015 produced a ValueError instead of giving the correct float.
2016
Eric Smitha5fa5a22008-07-16 00:11:49 +00002017- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2018 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2019
Mark Dickinson7103aa42008-07-15 19:08:33 +00002020- Issue #3008: the float type has a new instance method 'float.hex'
2021 and a new class method 'float.fromhex' to convert floating-point
2022 numbers to and from hexadecimal strings, respectively.
2023
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002024- Issue #2235: __hash__ is once again inherited by default. To allow
2025 collections.Hashable to remain meaningful in the presence of the
2026 default hash implementation (object.__hash__), it is now possible
2027 to explicit block inheritance of hash by setting __hash__=None at
2028 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2029 level.
2030
Nick Coghlanb028f502008-07-13 14:52:36 +00002031- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2032 the parent module cannot be found while performing an absolute import.
2033 This means that an incorrectly defined __package__ attribute will
2034 now only prevent relative imports in that module rather than causing
2035 all imports from that module to fail.
2036
Nick Coghlan14ff9942008-07-08 14:21:42 +00002037- Issue #2517: Allow unicode messages in Exceptions again by correctly

2046 threading.local: the first member set by a thread could be saved in
2047 another thread's dictionary.
2048
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002049- Issue #3004: Minor change to slice.indices(): the start and stop
2050 arguments are now treated identically, making the behaviour easier
2051 to describe and understand. For example, slice(None, -10,
2052 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2053 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2054 10, -1).
2055
Georg Brandl278fc502008-07-19 12:46:12 +00002056- Issue #3219: Calling a function with repeated keyword arguments,
2057 f(a=2, a=23), would not cause a syntax error. This was a regression
2058 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002059
Georg Brandl278fc502008-07-19 12:46:12 +00002060- Issue #2862: Make int and float freelist management consistent with
2061 other freelists. Changes their CompactFreeList apis into
2062 ClearFreeList apis and calls them via gc.collect().

2068 api functions without holding the GIL, which could lead to a fatal
2069 error when they failed.
2070
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002071- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002096- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2097 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002098 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002099 content-length. The problem had been corrected in the 2.4 branch, but never
2100 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002115- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2116 handling is now the same as that of other special attributes like __name__).

2572 using the 'warning's machinery in such places as the parser where
2573 use of pure Python code is not possible. Both the ``showarning()``
2574 and ``formatwarning()`` gain an optional 'line' argument which is
2575 not called by default for backwards-compatibility reasons. Setting
2576 ``warnings.showwarning()`` to an implementation that lacks support
2577 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002640- Issue #2550: The approach used by client/server code for obtaining
2641 ports to listen on in network-oriented tests has been refined in an
2642 effort to facilitate running multiple instances of the entire
2643 regression test suite in parallel without issue.
2644 test_support.bind_port() has been fixed such that it will always
2645 return a unique port -- which wasn't always the case with the
2646 previous implementation, especially if socket options had been set
2647 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2648 new implementation of bind_port() will actually raise an exception
2649 if it is passed an AF_INET/SOCK_STREAM socket with either the
2650 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2651 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2652 the socket it's been passed. This currently only applies to
2653 Windows. This option prevents any other sockets from binding to the
2654 host/port we've bound to, thus removing the possibility of the
2655 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2656 when a second SOCK_STREAM socket binds and accepts to a host/port
2657 that's already been bound by another socket. The optional preferred
2658 port parameter to bind_port() has been removed. Under no
2659 circumstances should tests be hard coding ports!
2660
2661 test_support.find_unused_port() has also been introduced, which will
2662 pass a temporary socket object to bind_port() in order to obtain an
2663 unused port. The temporary socket object is then closed and
2664 deleted, and the port is returned. This method should only be used
2665 for obtaining an unused port in order to pass to an external program
2666 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2667 a parameter to a server-oriented class that doesn't give you direct
2668 access to the underlying socket used.
2669
2670 Finally, test_support.HOST has been introduced, which should be used
2671 for the host argument of any relevant socket calls (i.e. bind and
2672 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002673
2674 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002675 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002676 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2677 test_asynchat and test_socket_ssl.
2678
Georg Brandl3ee81df2008-05-17 18:14:43 +00002679 It is now possible for multiple instances of the regression test
2680 suite to run in parallel without issue.

2947-----------------
2948
Fred Drakea8ee94b2008-03-01 02:45:07 +00002949- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002950 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002952- Issue #2067: file.__exit__() now calls subclasses' close() method.
2953
2954- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002955
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002956- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002957 issue 215555 for a discussion.
2958
Eric Smitha73fbe72008-02-23 03:09:44 +00002959- Added the future_builtins module, which contains hex() and oct().
2960 These are the PEP 3127 version of these functions, designed to be
2961 compatible with the hex() and oct() builtins from Python 3.0. They
2962 differ slightly in their output formats from the existing, unchanged
2963 Python 2.6 builtins. The expected usage of the future_builtins
2964 module is:
2965 from future_builtins import hex, oct
2966
Eric Smith7ef40bf2008-02-20 23:34:22 +00002967- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2968 exponents for exponents with absolute value < 100. Follows C99
2969 standard. This is a change on Windows, which would use 3 digits.
2970 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2971 so that any alterations it does to the resulting string will be
2972 available in stringlib/formatter.h (for float.__format__).
2973
Eric Smith5a3c1352008-02-19 13:21:56 +00002974- Implemented PEP 3101, Advanced String Formatting. This adds a new
2975 builtin format(); a format() method for str and unicode; a
2976 __format__() method to object, str, unicode, int, long, float, and
2977 datetime; the class string.Formatter; and the C API
2978 PyObject_Format().
2979
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980- Fixed several potential crashes, all caused by specially crafted
2981 __del__ methods exploiting objects in temporarily inconsistent
2982 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002983
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002984- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985 prevent a possible crash: an Abstract Base Class would try to access
2986 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002987

Georg Brandl3ee81df2008-05-17 18:14:43 +00002991- Clear all free lists during a gc.collect() of the highest generation
2992 in order to allow pymalloc to free more arenas. Python may give back
2993 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002994
Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Issue #2045: Fix an infinite recursion triggered when printing a
2996 subclass of collections.defaultdict, if its default_factory is set
2997 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002998
Christian Heimesf75dbef2008-02-08 00:11:31 +00002999- Fixed a minor memory leak in dictobject.c. The content of the free
3000 list was not freed on interpreter shutdown.
3001
Georg Brandl3ee81df2008-05-17 18:14:43 +00003002- Limit free list of method and builtin function objects to 256
3003 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003005- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3006 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003007 to compact the internal free lists of pre-allocted ints and floats.
3008
Georg Brandl3ee81df2008-05-17 18:14:43 +00003009- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3010 calls. Python expected the return type int but the fork familie
3011 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003012
Georg Brandl3ee81df2008-05-17 18:14:43 +00003013- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3023 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003024
Georg Brandl3ee81df2008-05-17 18:14:43 +00003025- Patch #1473257: generator objects gain a gi_code attribute. This is
3026 the same object as the func_code attribute of the function that
3027 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003028
Georg Brandl3ee81df2008-05-17 18:14:43 +00003029- Issue #1920: "while 0" statements were completely removed by the
3030 compiler, even in the presence of an "else" clause, which is
3031 supposed to be run when the condition is false. Now the compiler
3032 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003033
Guido van Rossumeead05f2008-01-24 18:21:02 +00003034- A few crashers fixed: weakref_in_del.py (issue #1377858);
3035 loosing_dict_ref.py (issue #1303614, test67.py);
3036 borrowed_ref_[34].py (not in tracker).
3037
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003038- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003039 suppressed while an extension is loaded by calling SetErrorMode in

3041
Georg Brandl3ee81df2008-05-17 18:14:43 +00003042- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003043 several extension methods and modules do not work without unicode
3044 support.
3045
Georg Brandl26543b12008-01-21 18:36:51 +00003046- Issue #1882: when compiling code from a string, encoding cookies in the

3050
Georg Brandl6caad7d2008-01-26 14:19:22 +00003051- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003052 added.
3053
Christian Heimesc94e2b52008-01-14 04:13:37 +00003054- sys.float_info / PyFloat_GetInfo: The floating point information
3055 object was converted from a dict to a specialized structseq object.
3056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Patch #1816: Added sys.flags structseq. It exposes the status of
3058 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003059
Georg Brandl3ee81df2008-05-17 18:14:43 +00003060- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Patch #1700288: added a type attribute cache that caches method
3065 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003066
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003067- Bug #1776: __import__() no longer accepts filenames on any platform.
3068 The first parameter to __import__() must be a valid module name.

3073 envvar and sys.dont_write_bytecode attribute. All these can be set
3074 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003076- Improve some exception messages when Windows fails to load an
3077 extension module. Now we get for example '%1 is not a valid Win32
3078 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003085- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003086 and INF. float("nan"), float("inf") and float("-inf") now work on
3087 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003089- Compiler now generates simpler and faster code for dictionary
3090 literals. The oparg for BUILD_MAP now indicates an estimated
3091 dictionary size. There is a new opcode, STORE_MAP, for adding
3092 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003121- Patch #1739468: Directories and zipfiles containing a __main__.py
3122 file can now be directly executed by passing their name to the
3123 interpreter. The directory/zipfile is automatically inserted as the
3124 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Issue #1265: Fix a problem with sys.settrace, if the tracing
3127 function uses a generator expression when at the same time the
3128 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003129
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003130- sets and frozensets now have an isdisjoint() method.

3133
Neal Norwitz44f326e2007-10-05 05:29:17 +00003134- Fix warnings found by the new version of the Coverity checker.
3135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- The enumerate() builtin function is no longer bounded to sequences
3137 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3138 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003139
Georg Brandl3ee81df2008-05-17 18:14:43 +00003140- Issue #1686386: Tuple's tp_repr did not take into account the
3141 possibility of having a self-referential tuple, which is possible
3142 from C code. Nor did object's tp_str consider that a type's tp_str
3143 could do something that could lead to an inifinite recursion.
3144 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3145 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003146
Georg Brandl3ee81df2008-05-17 18:14:43 +00003147- Issue #1164: It was possible to trigger deadlock when using the
3148 'print' statement to write to a file since the GIL was not released
3149 as needed. Now PyObject_Print() does the right thing along with
3150 various tp_print implementations of the built-in types and those in
3151 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003152
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153- Issue #1147: Exceptions were directly allowing string exceptions in
3154 their throw() method even though string exceptions no longer
3155 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003156
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157- Issue #1096: Prevent a segfault from getting the repr of a very
3158 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003159
Brett Cannon1e534b52007-09-07 04:18:30 +00003160- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161 PyObject_Call() never calling back out to Python code to trigger
3162 recursion depth updates/checks. Required the creation of a static
3163 RuntimeError instance in case normalizing an exception put the
3164 recursion check value past its limit. Fixes crashers
3165 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003166

Neal Norwitz0ac60192007-05-27 04:08:54 +00003180- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003181 __*__ attributes. (Some already existed, e.g., __doc__ and
3182 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003183
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003184- Add -3 option to the interpreter to warn about features that are
3185 deprecated and will be changed/removed in Python 3.0.
3186
Georg Brandl2134e752007-05-21 20:34:16 +00003187- Patch #1686487: you can now pass any mapping after '**' in function
3188 calls.
3189
Collin Winter62903052007-05-18 23:11:24 +00003190- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191 "except E as target:". This is to provide forwards compatibility
3192 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003193
Brett Cannon229cee22007-05-05 01:34:02 +00003194- Deprecate BaseException.message as per PEP 352.
3195
Georg Brandl3ee81df2008-05-17 18:14:43 +00003196- Issue #1303614: don't expose object's __dict__ when the dict is

3198
Vinay Sajip8549ce32007-05-06 17:53:37 +00003199- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003200 setting a plain string, ie don't expand to single letter identifiers.
3201
Raymond Hettinger13936692007-04-11 18:40:58 +00003202- Request #1191699: Slices can now be pickled.
3203
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003204- Request #1193128: str.translate() now allows a None argument for
3205 translations that only remove characters without re-mapping the
3206 remaining characters.
3207
Georg Brandl5cb76c12007-03-21 09:00:39 +00003208- Patch #1682205: a TypeError while unpacking an iterable is no longer
3209 masked by a generic one with the message "unpack non-sequence".
3210
Neal Norwitzaa754b72007-03-21 06:39:48 +00003211- Remove unused file Python/fmod.c.
3212
Guido van Rossum143b5642007-03-23 04:58:42 +00003213- Bug #1683368: The object.__init__() and object.__new__() methods are
3214 now stricter in rejecting excess arguments. The only time when
3215 either allows excess arguments is when it is not overridden and the
3216 other one is. For backwards compatibility, when both are
3217 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003218 warning later). Also, type.__init__() insists on the same signature
3219 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003220
Georg Brandl3ee81df2008-05-17 18:14:43 +00003221- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3222 object to complex using its __complex__() method before falling back
3223 to the __float__() method. Therefore, the functions in the cmath
3224 module now can operate on objects that define a __complex__()
3225 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003226
Georg Brandl3ee81df2008-05-17 18:14:43 +00003227- Patch #1623563: allow __class__ assignment for classes with
3228 __slots__. The old and the new class are still required to have the
3229 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003230
Georg Brandl3ee81df2008-05-17 18:14:43 +00003231- Patch #1642547: Fix an error/crash when encountering syntax errors

3235 ``object.__reduce_ex__()`` is called with an object that is faking
3236 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003237
Georg Brandl3ee81df2008-05-17 18:14:43 +00003238- Patch #1680015: Don't modify __slots__ tuple if it contains an

3242
Georg Brandl7b9c5552007-03-12 14:30:05 +00003243- Bug #1678647: write a newline after printing an exception in any
3244 case, even when converting the value to a string failed.
3245
Georg Brandl871f1bc2007-03-12 13:17:36 +00003246- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003247 its argument, if it exists. If not, it will work like before. This
3248 allows customizing the output of dir() in the presence of a
3249 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003250
Collin Winter276887b2007-03-12 16:11:39 +00003251- Patch #922167: Python no longer segfaults when faced with infinitely
3252 self-recursive reload() calls (as reported by bug #742342).
3253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- Patch #1675981: remove unreachable code from ``type.__new__()``

3258 parthensized forms. This means complex(repr(x)) now works instead of
3259 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003260
Georg Brandlaa2321b2007-03-07 00:40:28 +00003261- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262 makes the filenames the warning module prints much more sensible
3263 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003264
Georg Brandl49aafc92007-03-07 00:34:46 +00003265- Variant of patch #697613: don't exit the interpreter on a SystemExit
3266 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003267 variable is given, but break into the interactive interpreter just
3268 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003276- Patch #1674228: when assigning a slice (old-style), check for the
3277 sq_ass_slice instead of the sq_slice slot.
3278
Georg Brandl3ee81df2008-05-17 18:14:43 +00003279- When printing an unraisable error, don't print exceptions. before
3280 the name. This duplicates the behavior whening normally printing
3281 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003814 AttributeError instead of an IOError when the server's response
3815 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003816

Georg Brandl3ee81df2008-05-17 18:14:43 +00003821- Patch #1429539: pdb now correctly initializes the __main__ module
3822 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003823 correctly now.
3824

3831
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832- Patch #1530482: add pydoc.render_doc() which returns the

3847
Georg Brandl92a6bae2007-03-13 17:43:32 +00003848- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003849 are set for invalid interpolation sequences that would lead to
3850 errors on reading back those values.

3891

3893 returned string up to the first NUL character.
3894

3904
Georg Brandl3ee81df2008-05-17 18:14:43 +00003905- unittest now verifies more of its assumptions. In particular,
3906 TestCase and TestSuite subclasses (not instances) are no longer
3907 accepted in TestSuite.addTest(). This should cause no
3908 incompatibility since it never made sense with ordinary subclasses
3909 -- the failure just occurred later, with a more cumbersome
3910 exception.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004298- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004299 time so that opening a database previously created with the DB_DUP
4300 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4301 opens. Specifically: dictionary assignment to a DB object will
4302 replace all values for a given key when the database allows
4303 duplicate values. DB users should use DB.put(k, v) when they want
4304 to store duplicates; not DB[k] = v.

4311 characters with ASCII value less than 32. Also, it correctly quotes
4312 dots only if they occur on a single line, as opposed to the previous
4313 behavior of quoting dots if they are the second character of any
4314 line.

4660 of w# format code incorrectly truncated the length to an int, even
4661 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4662 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004692- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4693 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
