125 statement and correctly lookup the __enter__ and __exit__ special methods.
126
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000127- Issue #5829: complex("1e500") no longer raises OverflowError. This

140 rejected; (2) parsing of strings representing infinities and nans
141 was locale aware; and (3) the interpretation of fromhex('-nan')
142 didn't match that of float('-nan').
143
Eric Smitha985a3a2009-05-05 18:26:08 +0000144- Issue #5920: For float.__format__, change the behavior with the
145 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
146 to be like 'g' but with at least one decimal point and with a
147 default precision of 12. Previously, the behavior the same but with
148 a default precision of 6. This more closely matches str(), and
149 reduces surprises when adding alignment flags to the empty
150 presentation type. This also affects the new complex.__format__ in
151 the same way.
152
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000153- Issue #5890: in subclasses of 'property' the __doc__ attribute was

162
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000163- Issue #5864: Fix empty format code formatting for floats so that it
164 never gives more than the requested number of significant digits.
165

176
Mark Dickinson95bc9802009-04-24 12:46:53 +0000177- Issue #5816: complex(repr(z)) now recovers z exactly, even when
178 z involves nans, infs or negative zeros.
179
Eric Smithaca19e62009-04-22 13:29:05 +0000180- Implement PEP 378, Format Specifier for Thousands Separator, for
181 floats, ints, and longs.
182
183- Issue #5515: 'n' formatting for ints, longs, and floats handles
184 leading zero formatting poorly.
185
186- Issue #5772: For float.__format__, don't add a trailing ".0" if
187 we're using no type code and we have an exponent.
188

193 some builtin types.
194
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000195- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000196 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000197
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000198- Issue #5759: float() didn't call __float__ on str subclasses.

216 untrackable objects are not tracked by the garbage collector. This can
217 reduce the size of collections and therefore the garbage collection overhead
218 on long-running programs, depending on their particular use of datatypes.
219
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000220- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
221 improve its performance. Long divisions and remainder operations

223
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000224- Issue #4258: Make it possible to use base 2**30 instead of base
225 2**15 for the internal representation of integers, for performance
226 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
227 --enable-big-digits option to configure, which overrides the
228 default. Add sys.long_info structseq to provide information about
229 the internal format.
230

232 result traceback.__members__ no longer exists.)
233
Mark Dickinson6b265f12009-03-18 16:07:26 +0000234- Issue #4474: PyUnicode_FromWideChar now converts characters outside
235 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

237
Eric Smith6f42edb2009-03-14 11:57:26 +0000238- Issue #5237: Allow auto-numbered fields in str.format(). For
239 example: '{} {}'.format(1, 2) == '1 2'.
240
Brett Cannon6c4cff02009-03-11 04:51:06 +0000241- Issue #3652: Make the 'line' argument for warnings.showwarning() a
242 requirement. Means the DeprecationWarning from Python 2.6 can go away.
243

246 float arguments.
247

249 for ints and longs.
250
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000251- Issue #5260: Long integers now consume less memory: average
252 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
253 on a 64-bit system.
254
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000255- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
256 rotating the object pointer by 4 bits to the right.

260
Benjamin Petersone18ef192009-01-20 14:21:16 +0000261- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
262
Georg Brandl29c6a282009-04-05 20:23:13 +0000263- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000264 were suppressing all exceptions. These include list(), filter(), map(),
265 zip(), and bytearray().
266
Benjamin Peterson596d3062009-01-19 15:42:23 +0000267- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

307
Nick Coghlan180e4002008-12-30 01:18:48 +0000308- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
309 where the tp_hash and tp_dict slots are both NULL.
310
Benjamin Peterson7af65562008-12-29 17:56:58 +0000311- Issue #4764: With io.open, IOError.filename is set when trying to open a
312 directory on POSIX systems.
313
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000314- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
315 systems.
316
Georg Brandl6425a2f2008-12-28 11:54:53 +0000317- Issue #4759: None is now allowed as the first argument of
318 bytearray.translate(). It was always allowed for bytes.translate().
319
Skip Montanarof205c132008-12-23 03:30:15 +0000320- Added test case to ensure attempts to read from a file opened for writing
321 fail.
322
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000323- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
324 print elapsed times, not only when some objects are uncollectable /
325 unreachable. Original patch by Neil Schemenauer.

333 context manager returns a value that cannot be converted to a bool.
334
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000335- Issue #4597: Fixed several opcodes that weren't always propagating

337
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000338- Issue #4445: Replace "sizeof(PyStringObject)" with
339 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
340 str instances. On a typical machine this saves 3 bytes of memory
341 (on average) per string allocation.
342
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000343- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Vinay Sajip213faca2008-12-03 23:22:58 +0000353- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000354 method on file objects with closefd=False. The file descriptor is still
355 kept open but the file object behaves like a closed file. The ``FileIO``
356 object also got a new readonly attribute ``closefd``.
357
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000358- Issue #4348: Some bytearray methods returned that didn't cause any change to
359 the bytearray, returned the same bytearray instead of a copy.

366
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000367- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
368 exec statement.
369
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000370- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
371 method does not return iterators for the 4th and 5th items.
372
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000373- Issue #4209: Enabling unicode_literals and the print_function in the same
374 __future__ import didn't work.
375
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000376- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000377 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000378
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000379- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
380 returned a path longer than MAX_PATH. (But It's doubtful this code path is
381 really executed because I cannot move to such directory on win2k)
382
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000383- Issue #4069: When set.remove(element) is used with a set element, the element
384 is temporarily replaced with an equivalent frozenset. But the eventual
385 KeyError would always report the empty frozenset([]) as the missing key. Now
386 it correctly refers to the initial element.
387
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000388- Issue #4509: Various issues surrounding resize of bytearray objects to
389 which there are buffer exports.
390

398 short file names.
399
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000400- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
401 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000402
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000403- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
404 returned them on 64bit platforms.
405
Walter Dörwalded960ac2009-05-03 22:36:33 +0000406- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
407 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
408 step. This avoids problems with counting UTF-8 bytes that ignores the effect
409 of using the replace error handler in PyUnicode_DecodeUTF8().
410
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000411- Issue #3739: The unicode-internal encoder now reports the number of characters
412 consumed like any other encoder (instead of the number of bytes).

1426 Unicode category 'Nd' (Number, Decimal Digit). Previously it also
1427 matched characters with category 'No'.

Mark Dickinson5fd3af22009-07-07 15:08:28 +00001429- Issue #1523: Remove deprecated overflow wrapping for struct.pack
1430 with an integer format code ('bBhHiIlLqQ'). Packing an out-of-range
1431 integer now consistently raises struct.error.
1432
Mark Dickinson463dc4b2009-07-05 10:01:24 +00001433- Issues #1530559, #1741130: Fix various struct.pack inconsistencies

1445 TypeError used to be raised (with a confusing error message) for
1446 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

1495 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1496 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1497 skip the tests if DISPLAY is defined but can't be used.

Nick Coghlan5533ff62009-04-22 15:26:04 +00001502- Issue #5354: New test support function import_fresh_module() makes
1503 it easy to import both normal and optimised versions of modules.
1504 test_heapq and test_warnings have been adjusted to use it, tests for
1505 other modules with both C and Python implementations in the stdlib
1506 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00001514- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001515 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001516 from test support, which does the conversion.

1613
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001614- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1615 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1616 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1617 ``printf`` function, whereas PyString_FromFormat has an independent
1618 implementation and uses "%zd" on all platforms for size_t values.
1619 This makes a difference on win64, where ``printf`` needs "%Id" to display
1620 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001622- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001630- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001637 was correctly parsed but parsing of subsequent arguments failed.
1638
Vinay Sajip35e3b032008-09-01 14:33:59 +00001639- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001640 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1641 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1642 when given a tuple of classes as second argument, were looking up
1643 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1644 type object.
1645
Neal Norwitz18aa3882008-08-24 05:04:52 +00001646- Fix crashes on memory allocation failure found with failmalloc.

1715 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1716 for catch_warnings() also led to an improvement in the raising of a
1717 DeprecationWarning related to warnings.warn_explicit().
1718

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001783What's New in Python 2.6 beta 3?
1784================================
1785
Barry Warsaw07a4a382008-08-21 01:15:08 +00001786*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001787
1788Core and Builtins
1789-----------------
1790
Guido van Rossumf8402962008-08-20 15:01:50 +00001791- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1792 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1793 extensions do not automatically benefit from the class attribute
1794 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1795 to their tp_flags field if they care. This is a backwards
1796 compatibility feature; in 3.0, all types will use the cache by
1797 default.
1798
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001799- Keyword arguments can now follow starred arguments. (``f(a, *args,
1800 keyword=23)`` is now valid syntax.)
1801
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001802- ctypes function pointers that are COM methods have a boolean True
1803 value again.
1804
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001805- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1806 by denying s# to parse objects that have a releasebuffer procedure,
1807 and introducing s*.
1808
Georg Brandl1e13ea92008-08-11 09:07:59 +00001809- Issue #3537: Fix an assertion failure when an empty but presized dict
1810 object was stored in the freelist.
1811
Mark Dickinsonb6467572008-08-04 21:30:09 +00001812- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1813 ValueError consistently across platforms.
1814
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001815- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1816 (64bit Unix, for example), unichr() would truncate its argument and return
1817 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1818
Neal Norwitze7d8be82008-07-31 17:17:14 +00001819- Apply security patches from Apple.
1820
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001821- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1822 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1823
Antoine Pitrou92f82162008-07-25 22:22:08 +00001824- Issue #1819: function calls with several named parameters are now on
1825 average 35% faster (as measured by pybench).
1826
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001827- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1828 the python debugger steps into a class statement: the free variables (local
1829 variables defined in an outer scope) would be deleted from the outer scope.
1830
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001831- Issue #2620: Overflow checking when allocating or reallocating memory
1832 was not always being done properly in some python types and extension
1833 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1834 all been updated to perform better checks and places in the code that
1835 would previously leak memory on the error path when such an allocation
1836 failed have been fixed.
1837
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001838Library
1839-------
1840
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001841- Issue #3612: Added some missing basic types in ctypes.wintypes.
1842
Benjamin Petersone977ad42008-08-20 01:42:01 +00001843- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1844 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1845
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001846- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1847 version reported by these tools does not necessarily follow the python
1848 version numbering scheme, so the module is less strict when parsing it.
1849
Nick Coghlanf70385a2008-08-18 12:42:46 +00001850- Issue #2235: Added Py3k warnings for types which will become unhashable
1851 under the stricter __hash__ inheritance rules in 3.0. Several types
1852 which did not meet the rules for hash invariants and were already
1853 unhashable in 3.0 have now been explicitly flagged as unhashable in
1854 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1855 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1856
Brett Cannon88f801d2008-08-18 00:46:22 +00001857- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1858 imported into the module but exposed as part of the module's API.

1861
Brett Cannon46225e72008-08-18 00:36:52 +00001862- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001864- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1865
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001866- Issue #3575: Incremental decoder's decode function now takes bytearray
1867 by using 's*' instead of 't#'.
1868
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001869- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001870 fails unicode conversion on 2nd parameter. (windows only)
1871
Facundo Batista94f243a2008-08-17 03:38:39 +00001872- Issue 2464. urllib2 now supports a malformation in the URL received
1873 in a redirect.
1874
Brett Cannonabe423e2008-08-16 21:47:07 +00001875- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001876 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001877
Facundo Batistaeb90b782008-08-16 14:44:07 +00001878- Issue #2776: fixed small issue when handling an URL with double slash
1879 after a 302 response in the case of not going through a proxy.
1880
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001881- Issue #2676: in the email package, content-type parsing was hanging on
1882 pathological input because of quadratic or exponential behaviour of a
1883 regular expression.
1884
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001885- Issue #3476: binary buffered reading through the new "io" library is now
1886 thread-safe.
1887
Brett Cannonbf3157b2008-08-14 05:00:03 +00001888- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1889 since mimetools itself is deprecated. Because modules are cached, all
1890 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1891
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001892- Issue #3134: shutil referenced undefined WindowsError symbol.
1893
Robert Schuppenies14646332008-08-10 11:01:53 +00001894- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1895 menu entries were not deleted.
1896
Brett Cannon83e81842008-08-09 23:30:55 +00001897- Copied the implementation of reduce() to _functools.reduce() to have a
1898 version that did not raise a DeprecationWarning under -3.
1899
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001900- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1901 a MemoryError rather than silently stop the iteration.
1902
Guido van Rossum59ce9012008-08-09 14:55:34 +00001903- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1904 to _sre.compile() will now be rejected. This should not affect anybody
1905 since the re.compile() function never generates invalid re-bytecode.
1906
Skip Montanaroa032bf42008-08-08 22:52:51 +00001907- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00001926 asking for a specific length. This problem only affected files opened
1927 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001928

1954 mode 0600 rather than 000 under Unix.
1955
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001956- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Mark Dickinson64b7e502008-07-16 09:40:03 +00001989- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1990 produced a ValueError instead of giving the correct float.
1991
Eric Smitha5fa5a22008-07-16 00:11:49 +00001992- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

1994
Mark Dickinson7103aa42008-07-15 19:08:33 +00001995- Issue #3008: the float type has a new instance method 'float.hex'
1996 and a new class method 'float.fromhex' to convert floating-point
1997 numbers to and from hexadecimal strings, respectively.
1998
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001999- Issue #2235: __hash__ is once again inherited by default. To allow
2000 collections.Hashable to remain meaningful in the presence of the
2001 default hash implementation (object.__hash__), it is now possible
2002 to explicit block inheritance of hash by setting __hash__=None at
2003 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2004 level.
2005
Nick Coghlanb028f502008-07-13 14:52:36 +00002006- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2007 the parent module cannot be found while performing an absolute import.
2008 This means that an incorrectly defined __package__ attribute will
2009 now only prevent relative imports in that module rather than causing
2010 all imports from that module to fail.
2011
Nick Coghlan14ff9942008-07-08 14:21:42 +00002012- Issue #2517: Allow unicode messages in Exceptions again by correctly

2023
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002024- Issue #3004: Minor change to slice.indices(): the start and stop
2025 arguments are now treated identically, making the behaviour easier
2026 to describe and understand. For example, slice(None, -10,
2027 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2028 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2029 10, -1).

2032 f(a=2, a=23), would not cause a syntax error. This was a regression
2033 from 2.4 caused by the switch to the new compiler.

2072 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002073 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00002545- Issue #1631171: Re-implement the 'warnings' module in C (the
2546 original Python code has been kept as backup). This will allow for
2547 using the 'warning's machinery in such places as the parser where
2548 use of pure Python code is not possible. Both the ``showarning()``
2549 and ``formatwarning()`` gain an optional 'line' argument which is
2550 not called by default for backwards-compatibility reasons. Setting
2551 ``warnings.showwarning()`` to an implementation that lacks support
2552 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002615- Issue #2550: The approach used by client/server code for obtaining
2616 ports to listen on in network-oriented tests has been refined in an
2617 effort to facilitate running multiple instances of the entire
2618 regression test suite in parallel without issue.
2619 test_support.bind_port() has been fixed such that it will always
2620 return a unique port -- which wasn't always the case with the
2621 previous implementation, especially if socket options had been set
2622 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2623 new implementation of bind_port() will actually raise an exception
2624 if it is passed an AF_INET/SOCK_STREAM socket with either the
2625 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2626 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2627 the socket it's been passed. This currently only applies to
2628 Windows. This option prevents any other sockets from binding to the
2629 host/port we've bound to, thus removing the possibility of the
2630 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2631 when a second SOCK_STREAM socket binds and accepts to a host/port
2632 that's already been bound by another socket. The optional preferred
2633 port parameter to bind_port() has been removed. Under no
2634 circumstances should tests be hard coding ports!
2635
2636 test_support.find_unused_port() has also been introduced, which will
2637 pass a temporary socket object to bind_port() in order to obtain an
2638 unused port. The temporary socket object is then closed and
2639 deleted, and the port is returned. This method should only be used
2640 for obtaining an unused port in order to pass to an external program
2641 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2642 a parameter to a server-oriented class that doesn't give you direct
2643 access to the underlying socket used.
2644
2645 Finally, test_support.HOST has been introduced, which should be used
2646 for the host argument of any relevant socket calls (i.e. bind and
2647 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002648
2649 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002650 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002651 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2652 test_asynchat and test_socket_ssl.
2653
Georg Brandl3ee81df2008-05-17 18:14:43 +00002654 It is now possible for multiple instances of the regression test
2655 suite to run in parallel without issue.

2922-----------------
2923
Fred Drakea8ee94b2008-03-01 02:45:07 +00002924- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002925 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002926
Georg Brandlad61bc82008-02-23 15:11:18 +00002927- Issue #2067: file.__exit__() now calls subclasses' close() method.
2928
2929- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002930
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002931- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002932 issue 215555 for a discussion.
2933
Eric Smitha73fbe72008-02-23 03:09:44 +00002934- Added the future_builtins module, which contains hex() and oct().
2935 These are the PEP 3127 version of these functions, designed to be
2936 compatible with the hex() and oct() builtins from Python 3.0. They
2937 differ slightly in their output formats from the existing, unchanged
2938 Python 2.6 builtins. The expected usage of the future_builtins
2939 module is:
2940 from future_builtins import hex, oct
2941
Eric Smith7ef40bf2008-02-20 23:34:22 +00002942- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2943 exponents for exponents with absolute value < 100. Follows C99
2944 standard. This is a change on Windows, which would use 3 digits.
2945 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2946 so that any alterations it does to the resulting string will be
2947 available in stringlib/formatter.h (for float.__format__).
2948
Eric Smith5a3c1352008-02-19 13:21:56 +00002949- Implemented PEP 3101, Advanced String Formatting. This adds a new
2950 builtin format(); a format() method for str and unicode; a
2951 __format__() method to object, str, unicode, int, long, float, and
2952 datetime; the class string.Formatter; and the C API
2953 PyObject_Format().
2954
Georg Brandl3ee81df2008-05-17 18:14:43 +00002955- Fixed several potential crashes, all caused by specially crafted
2956 __del__ methods exploiting objects in temporarily inconsistent
2957 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002958
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002959- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002960 prevent a possible crash: an Abstract Base Class would try to access
2961 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002962
Georg Brandl3ee81df2008-05-17 18:14:43 +00002963- Fixed repr() and str() of complex numbers with infinity or nan as
2964 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002965
Georg Brandl3ee81df2008-05-17 18:14:43 +00002966- Clear all free lists during a gc.collect() of the highest generation
2967 in order to allow pymalloc to free more arenas. Python may give back
2968 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002969
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970- Issue #2045: Fix an infinite recursion triggered when printing a
2971 subclass of collections.defaultdict, if its default_factory is set
2972 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002973
Christian Heimesf75dbef2008-02-08 00:11:31 +00002974- Fixed a minor memory leak in dictobject.c. The content of the free
2975 list was not freed on interpreter shutdown.
2976
Georg Brandl3ee81df2008-05-17 18:14:43 +00002977- Limit free list of method and builtin function objects to 256
2978 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002979
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2981 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002982 to compact the internal free lists of pre-allocted ints and floats.
2983
Georg Brandl3ee81df2008-05-17 18:14:43 +00002984- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2985 calls. Python expected the return type int but the fork familie
2986 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002987
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2989 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002990
Georg Brandl3ee81df2008-05-17 18:14:43 +00002991- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2992 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002993
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2995 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002997- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2998 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002999
Georg Brandl3ee81df2008-05-17 18:14:43 +00003000- Patch #1473257: generator objects gain a gi_code attribute. This is
3001 the same object as the func_code attribute of the function that
3002 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003003
Georg Brandl3ee81df2008-05-17 18:14:43 +00003004- Issue #1920: "while 0" statements were completely removed by the
3005 compiler, even in the presence of an "else" clause, which is
3006 supposed to be run when the condition is false. Now the compiler
3007 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003008
Guido van Rossumeead05f2008-01-24 18:21:02 +00003009- A few crashers fixed: weakref_in_del.py (issue #1377858);
3010 loosing_dict_ref.py (issue #1303614, test67.py);
3011 borrowed_ref_[34].py (not in tracker).
3012
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003013- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003014 suppressed while an extension is loaded by calling SetErrorMode in
3015 dynload_win.c. The error is still reported properly.
3016
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003018 several extension methods and modules do not work without unicode
3019 support.
3020
Georg Brandl26543b12008-01-21 18:36:51 +00003021- Issue #1882: when compiling code from a string, encoding cookies in the
3022 second line of code were not always recognized correctly.
3023
Georg Brandl14404b62008-01-19 19:27:05 +00003024- Issue #1679: "0x" was taken as a valid integer literal.
3025
Georg Brandl6caad7d2008-01-26 14:19:22 +00003026- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003027 added.
3028
Christian Heimesc94e2b52008-01-14 04:13:37 +00003029- sys.float_info / PyFloat_GetInfo: The floating point information
3030 object was converted from a dict to a specialized structseq object.
3031
Georg Brandl3ee81df2008-05-17 18:14:43 +00003032- Patch #1816: Added sys.flags structseq. It exposes the status of
3033 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003034
Georg Brandl3ee81df2008-05-17 18:14:43 +00003035- Objects/structseq.c: Implemented new structseq representation. The
3036 patch makes structseqs (e.g. the return value of os.stat) more
3037 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003038
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039- Patch #1700288: added a type attribute cache that caches method
3040 accesses, resulting in speedups in heavily object-oriented code.

3049 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003050
Georg Brandl3ee81df2008-05-17 18:14:43 +00003051- Improve some exception messages when Windows fails to load an
3052 extension module. Now we get for example '%1 is not a valid Win32
3053 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003054

Georg Brandl3ee81df2008-05-17 18:14:43 +00003064- Compiler now generates simpler and faster code for dictionary
3065 literals. The oparg for BUILD_MAP now indicates an estimated
3066 dictionary size. There is a new opcode, STORE_MAP, for adding
3067 entries to the dictionary.

3110
Georg Brandl3ee81df2008-05-17 18:14:43 +00003111- The enumerate() builtin function is no longer bounded to sequences
3112 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3113 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003114
Georg Brandl3ee81df2008-05-17 18:14:43 +00003115- Issue #1686386: Tuple's tp_repr did not take into account the
3116 possibility of having a self-referential tuple, which is possible
3117 from C code. Nor did object's tp_str consider that a type's tp_str
3118 could do something that could lead to an inifinite recursion.
3119 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3120 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003121
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122- Issue #1164: It was possible to trigger deadlock when using the
3123 'print' statement to write to a file since the GIL was not released
3124 as needed. Now PyObject_Print() does the right thing along with
3125 various tp_print implementations of the built-in types and those in
3126 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00003135- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136 PyObject_Call() never calling back out to Python code to trigger
3137 recursion depth updates/checks. Required the creation of a static
3138 RuntimeError instance in case normalizing an exception put the
3139 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00003156 __*__ attributes. (Some already existed, e.g., __doc__ and
3157 __name__.)

3164
Collin Winter62903052007-05-18 23:11:24 +00003165- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003166 "except E as target:". This is to provide forwards compatibility
3167 with Python 3.0.

3173
Vinay Sajip8549ce32007-05-06 17:53:37 +00003174- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003175 setting a plain string, ie don't expand to single letter identifiers.
3176
Raymond Hettinger13936692007-04-11 18:40:58 +00003177- Request #1191699: Slices can now be pickled.

3187
Guido van Rossum143b5642007-03-23 04:58:42 +00003188- Bug #1683368: The object.__init__() and object.__new__() methods are
3189 now stricter in rejecting excess arguments. The only time when
3190 either allows excess arguments is when it is not overridden and the
3191 other one is. For backwards compatibility, when both are
3192 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003193 warning later). Also, type.__init__() insists on the same signature
3194 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003195
Georg Brandl3ee81df2008-05-17 18:14:43 +00003196- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3197 object to complex using its __complex__() method before falling back
3198 to the __float__() method. Therefore, the functions in the cmath
3199 module now can operate on objects that define a __complex__()
3200 method.

3217
Georg Brandl7b9c5552007-03-12 14:30:05 +00003218- Bug #1678647: write a newline after printing an exception in any
3219 case, even when converting the value to a string failed.
3220
Georg Brandl871f1bc2007-03-12 13:17:36 +00003221- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003222 its argument, if it exists. If not, it will work like before. This
3223 allows customizing the output of dir() in the presence of a
3224 __getattr__().

3233 parthensized forms. This means complex(repr(x)) now works instead of
3234 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003235
Georg Brandlaa2321b2007-03-07 00:40:28 +00003236- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237 makes the filenames the warning module prints much more sensible
3238 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003251- Patch #1674228: when assigning a slice (old-style), check for the
3252 sq_ass_slice instead of the sq_slice slot.
3253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003357 generator expressions (x for x, in ... ) works again. Fixing this
3358 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00003398- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00003807- Patch #1530482: add pydoc.render_doc() which returns the

3822
Georg Brandl92a6bae2007-03-13 17:43:32 +00003823- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824 are set for invalid interpolation sequences that would lead to
3825 errors on reading back those values.

3879
Georg Brandl3ee81df2008-05-17 18:14:43 +00003880- unittest now verifies more of its assumptions. In particular,
3881 TestCase and TestSuite subclasses (not instances) are no longer
3882 accepted in TestSuite.addTest(). This should cause no
3883 incompatibility since it never made sense with ordinary subclasses
3884 -- the failure just occurred later, with a more cumbersome
3885 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004172 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004273- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004274 time so that opening a database previously created with the DB_DUP
4275 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4276 opens. Specifically: dictionary assignment to a DB object will
4277 replace all values for a given key when the database allows
4278 duplicate values. DB users should use DB.put(k, v) when they want
4279 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004280

4286 characters with ASCII value less than 32. Also, it correctly quotes
4287 dots only if they occur on a single line, as opposed to the previous
4288 behavior of quoting dots if they are the second character of any
4289 line.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004558- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004559 periodic threadstate and signal checking in tight loops. By
4560 default, this option is turned-off. It should only be enabled in
4561 debugged, performance critical applications.

4617 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004618
Georg Brandl3ee81df2008-05-17 18:14:43 +00004619- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4620 to ``PyTuple_SetItem``, it can be used to populate a brand new

4633
Georg Brandl3ee81df2008-05-17 18:14:43 +00004634- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4635 of w# format code incorrectly truncated the length to an int, even
4636 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4637 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004638

Georg Brandl3ee81df2008-05-17 18:14:43 +00004667- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4668 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004669
Georg Brandl3ee81df2008-05-17 18:14:43 +00004670- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4680 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004681

Georg Brandl3ee81df2008-05-17 18:14:43 +00004695- Removed the macfs module. It had been deprecated since Python 2.5.
4696 This lead to the deprecation of macostools.touched() as it relied
4697 solely on macfs and was a no-op under OS X.
