122 statement and correctly lookup the __enter__ and __exit__ special methods.
123
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000124- Issue #5829: complex("1e500") no longer raises OverflowError. This

136 (1) inf and nan strings with trailing whitespace were incorrectly
137 rejected; (2) parsing of strings representing infinities and nans
138 was locale aware; and (3) the interpretation of fromhex('-nan')
139 didn't match that of float('-nan').
140
Eric Smitha985a3a2009-05-05 18:26:08 +0000141- Issue #5920: For float.__format__, change the behavior with the
142 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
143 to be like 'g' but with at least one decimal point and with a
144 default precision of 12. Previously, the behavior the same but with
145 a default precision of 6. This more closely matches str(), and
146 reduces surprises when adding alignment flags to the empty
147 presentation type. This also affects the new complex.__format__ in
148 the same way.
149
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000150- Issue #5890: in subclasses of 'property' the __doc__ attribute was

159
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000160- Issue #5864: Fix empty format code formatting for floats so that it

173
Mark Dickinson95bc9802009-04-24 12:46:53 +0000174- Issue #5816: complex(repr(z)) now recovers z exactly, even when
175 z involves nans, infs or negative zeros.
176
Eric Smithaca19e62009-04-22 13:29:05 +0000177- Implement PEP 378, Format Specifier for Thousands Separator, for
178 floats, ints, and longs.
179
180- Issue #5515: 'n' formatting for ints, longs, and floats handles
181 leading zero formatting poorly.
182

184 we're using no type code and we have an exponent.
185

190 some builtin types.
191
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000192- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000193 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000194
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000195- Issue #5759: float() didn't call __float__ on str subclasses.

213 untrackable objects are not tracked by the garbage collector. This can
214 reduce the size of collections and therefore the garbage collection overhead
215 on long-running programs, depending on their particular use of datatypes.
216
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000217- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
218 improve its performance. Long divisions and remainder operations

220
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000221- Issue #4258: Make it possible to use base 2**30 instead of base
222 2**15 for the internal representation of integers, for performance
223 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
224 --enable-big-digits option to configure, which overrides the
225 default. Add sys.long_info structseq to provide information about
226 the internal format.
227
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000228- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
229 result traceback.__members__ no longer exists.)
230
Mark Dickinson6b265f12009-03-18 16:07:26 +0000231- Issue #4474: PyUnicode_FromWideChar now converts characters outside
232 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

234
Eric Smith6f42edb2009-03-14 11:57:26 +0000235- Issue #5237: Allow auto-numbered fields in str.format(). For
236 example: '{} {}'.format(1, 2) == '1 2'.
237
Brett Cannon6c4cff02009-03-11 04:51:06 +0000238- Issue #3652: Make the 'line' argument for warnings.showwarning() a
239 requirement. Means the DeprecationWarning from Python 2.6 can go away.
240
Eric Smithe9fb6862009-02-20 14:02:36 +0000241- Issue #5247: Improve error message when unknown format codes are

246 for ints and longs.
247
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000248- Issue #5260: Long integers now consume less memory: average
249 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
250 on a 64-bit system.
251
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000252- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
253 rotating the object pointer by 4 bits to the right.
254
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000255- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

257
Benjamin Petersone18ef192009-01-20 14:21:16 +0000258- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
259
Georg Brandl29c6a282009-04-05 20:23:13 +0000260- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000261 were suppressing all exceptions. These include list(), filter(), map(),
262 zip(), and bytearray().
263
Benjamin Peterson596d3062009-01-19 15:42:23 +0000264- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

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

Mark Dickinson826f3fe2008-12-05 21:55:28 +0000335- Issue #4445: Replace "sizeof(PyStringObject)" with
336 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for

338 (on average) per string allocation.
339
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000340- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000351 method on file objects with closefd=False. The file descriptor is still
352 kept open but the file object behaves like a closed file. The ``FileIO``
353 object also got a new readonly attribute ``closefd``.
354
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000355- Issue #4348: Some bytearray methods returned that didn't cause any change to

372
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000373- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000374 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000376- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
377 returned a path longer than MAX_PATH. (But It's doubtful this code path is
378 really executed because I cannot move to such directory on win2k)
379
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000380- Issue #4069: When set.remove(element) is used with a set element, the element
381 is temporarily replaced with an equivalent frozenset. But the eventual
382 KeyError would always report the empty frozenset([]) as the missing key. Now
383 it correctly refers to the initial element.

401 returned them on 64bit platforms.
402
Walter Dörwalded960ac2009-05-03 22:36:33 +0000403- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
404 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
405 step. This avoids problems with counting UTF-8 bytes that ignores the effect
406 of using the replace error handler in PyUnicode_DecodeUTF8().
407
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000408- Issue #3739: The unicode-internal encoder now reports the number of characters

1497 it easy to import both normal and optimised versions of modules.
1498 test_heapq and test_warnings have been adjusted to use it, tests for
1499 other modules with both C and Python implementations in the stdlib
1500 can be adjusted to use it over time.

Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001509 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001510 from test support, which does the conversion.

1607
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001608- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1609 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1610 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1611 ``printf`` function, whereas PyString_FromFormat has an independent
1612 implementation and uses "%zd" on all platforms for size_t values.
1613 This makes a difference on win64, where ``printf`` needs "%Id" to display
1614 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001616- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1620 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001631 was correctly parsed but parsing of subsequent arguments failed.
1632
Vinay Sajip35e3b032008-09-01 14:33:59 +00001633- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001634 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1635 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1636 when given a tuple of classes as second argument, were looking up
1637 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1638 type object.
1639
Neal Norwitz18aa3882008-08-24 05:04:52 +00001640- Fix crashes on memory allocation failure found with failmalloc.

1709 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1710 for catch_warnings() also led to an improvement in the raising of a
1711 DeprecationWarning related to warnings.warn_explicit().
1712

1735
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001736- Issue #2975: When compiling several extension modules with Visual Studio 2008
1737 from the same python interpreter, some environment variables would grow
1738 without limit.
1739
Benjamin Peterson37346b22008-08-23 20:27:43 +00001740- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001777What's New in Python 2.6 beta 3?
1778================================
1779
Barry Warsaw07a4a382008-08-21 01:15:08 +00001780*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001781
1782Core and Builtins
1783-----------------
1784
Guido van Rossumf8402962008-08-20 15:01:50 +00001785- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1786 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1787 extensions do not automatically benefit from the class attribute
1788 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1789 to their tp_flags field if they care. This is a backwards
1790 compatibility feature; in 3.0, all types will use the cache by
1791 default.
1792
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001793- Keyword arguments can now follow starred arguments. (``f(a, *args,
1794 keyword=23)`` is now valid syntax.)
1795
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001796- ctypes function pointers that are COM methods have a boolean True
1797 value again.
1798
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001799- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1800 by denying s# to parse objects that have a releasebuffer procedure,
1801 and introducing s*.
1802
Georg Brandl1e13ea92008-08-11 09:07:59 +00001803- Issue #3537: Fix an assertion failure when an empty but presized dict
1804 object was stored in the freelist.
1805
Mark Dickinsonb6467572008-08-04 21:30:09 +00001806- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1807 ValueError consistently across platforms.
1808
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001809- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1810 (64bit Unix, for example), unichr() would truncate its argument and return
1811 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1812
Neal Norwitze7d8be82008-07-31 17:17:14 +00001813- Apply security patches from Apple.
1814
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001815- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1816 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1817
Antoine Pitrou92f82162008-07-25 22:22:08 +00001818- Issue #1819: function calls with several named parameters are now on
1819 average 35% faster (as measured by pybench).
1820
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001821- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1822 the python debugger steps into a class statement: the free variables (local
1823 variables defined in an outer scope) would be deleted from the outer scope.
1824
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001825- Issue #2620: Overflow checking when allocating or reallocating memory
1826 was not always being done properly in some python types and extension
1827 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1828 all been updated to perform better checks and places in the code that
1829 would previously leak memory on the error path when such an allocation
1830 failed have been fixed.
1831
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001832Library
1833-------
1834
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001835- Issue #3612: Added some missing basic types in ctypes.wintypes.
1836
Benjamin Petersone977ad42008-08-20 01:42:01 +00001837- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1838 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1839
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001840- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1841 version reported by these tools does not necessarily follow the python
1842 version numbering scheme, so the module is less strict when parsing it.
1843
Nick Coghlanf70385a2008-08-18 12:42:46 +00001844- Issue #2235: Added Py3k warnings for types which will become unhashable
1845 under the stricter __hash__ inheritance rules in 3.0. Several types
1846 which did not meet the rules for hash invariants and were already
1847 unhashable in 3.0 have now been explicitly flagged as unhashable in
1848 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1849 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1850
Brett Cannon88f801d2008-08-18 00:46:22 +00001851- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1855
Brett Cannon46225e72008-08-18 00:36:52 +00001856- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001858- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1859
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001860- Issue #3575: Incremental decoder's decode function now takes bytearray
1861 by using 's*' instead of 't#'.
1862
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001863- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001864 fails unicode conversion on 2nd parameter. (windows only)
1865
Facundo Batista94f243a2008-08-17 03:38:39 +00001866- Issue 2464. urllib2 now supports a malformation in the URL received
1867 in a redirect.
1868
Brett Cannonabe423e2008-08-16 21:47:07 +00001869- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001870 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001871
Facundo Batistaeb90b782008-08-16 14:44:07 +00001872- Issue #2776: fixed small issue when handling an URL with double slash
1873 after a 302 response in the case of not going through a proxy.
1874
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001875- Issue #2676: in the email package, content-type parsing was hanging on
1876 pathological input because of quadratic or exponential behaviour of a
1877 regular expression.
1878
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001879- Issue #3476: binary buffered reading through the new "io" library is now
1880 thread-safe.
1881
Brett Cannonbf3157b2008-08-14 05:00:03 +00001882- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1883 since mimetools itself is deprecated. Because modules are cached, all
1884 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1885
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001886- Issue #3134: shutil referenced undefined WindowsError symbol.
1887
Robert Schuppenies14646332008-08-10 11:01:53 +00001888- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1889 menu entries were not deleted.
1890
Brett Cannon83e81842008-08-09 23:30:55 +00001891- Copied the implementation of reduce() to _functools.reduce() to have a
1892 version that did not raise a DeprecationWarning under -3.
1893
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001894- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1895 a MemoryError rather than silently stop the iteration.
1896
Guido van Rossum59ce9012008-08-09 14:55:34 +00001897- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1898 to _sre.compile() will now be rejected. This should not affect anybody
1899 since the re.compile() function never generates invalid re-bytecode.
1900
Skip Montanaroa032bf42008-08-08 22:52:51 +00001901- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00001920 asking for a specific length. This problem only affected files opened
1921 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001922

1948 mode 0600 rather than 000 under Unix.
1949
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001950- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1987 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1988
Mark Dickinson7103aa42008-07-15 19:08:33 +00001989- Issue #3008: the float type has a new instance method 'float.hex'
1990 and a new class method 'float.fromhex' to convert floating-point
1991 numbers to and from hexadecimal strings, respectively.
1992
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001993- Issue #2235: __hash__ is once again inherited by default. To allow
1994 collections.Hashable to remain meaningful in the presence of the
1995 default hash implementation (object.__hash__), it is now possible
1996 to explicit block inheritance of hash by setting __hash__=None at
1997 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1998 level.
1999
Nick Coghlanb028f502008-07-13 14:52:36 +00002000- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2001 the parent module cannot be found while performing an absolute import.
2002 This means that an incorrectly defined __package__ attribute will
2003 now only prevent relative imports in that module rather than causing
2004 all imports from that module to fail.
2005
Nick Coghlan14ff9942008-07-08 14:21:42 +00002006- Issue #2517: Allow unicode messages in Exceptions again by correctly

2016 another thread's dictionary.
2017
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002018- Issue #3004: Minor change to slice.indices(): the start and stop
2019 arguments are now treated identically, making the behaviour easier
2020 to describe and understand. For example, slice(None, -10,
2021 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2022 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2023 10, -1).
2024
Georg Brandl278fc502008-07-19 12:46:12 +00002025- Issue #3219: Calling a function with repeated keyword arguments,
2026 f(a=2, a=23), would not cause a syntax error. This was a regression
2027 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002028

2037 api functions without holding the GIL, which could lead to a fatal
2038 error when they failed.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002065- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2066 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002067 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002068 content-length. The problem had been corrected in the 2.4 branch, but never

2544 not called by default for backwards-compatibility reasons. Setting
2545 ``warnings.showwarning()`` to an implementation that lacks support
2546 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002609- Issue #2550: The approach used by client/server code for obtaining
2610 ports to listen on in network-oriented tests has been refined in an
2611 effort to facilitate running multiple instances of the entire
2612 regression test suite in parallel without issue.
2613 test_support.bind_port() has been fixed such that it will always
2614 return a unique port -- which wasn't always the case with the
2615 previous implementation, especially if socket options had been set
2616 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2617 new implementation of bind_port() will actually raise an exception
2618 if it is passed an AF_INET/SOCK_STREAM socket with either the
2619 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2620 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2621 the socket it's been passed. This currently only applies to
2622 Windows. This option prevents any other sockets from binding to the
2623 host/port we've bound to, thus removing the possibility of the
2624 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2625 when a second SOCK_STREAM socket binds and accepts to a host/port
2626 that's already been bound by another socket. The optional preferred
2627 port parameter to bind_port() has been removed. Under no
2628 circumstances should tests be hard coding ports!
2629
2630 test_support.find_unused_port() has also been introduced, which will
2631 pass a temporary socket object to bind_port() in order to obtain an
2632 unused port. The temporary socket object is then closed and
2633 deleted, and the port is returned. This method should only be used
2634 for obtaining an unused port in order to pass to an external program
2635 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2636 a parameter to a server-oriented class that doesn't give you direct
2637 access to the underlying socket used.
2638
2639 Finally, test_support.HOST has been introduced, which should be used
2640 for the host argument of any relevant socket calls (i.e. bind and
2641 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002642
2643 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002644 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002645 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2646 test_asynchat and test_socket_ssl.
2647
Georg Brandl3ee81df2008-05-17 18:14:43 +00002648 It is now possible for multiple instances of the regression test
2649 suite to run in parallel without issue.

2816 values on 32-bit vs. 64-bit python interpreters. Both were correct,
2817 but they now both return a signed integer object for consistency.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002833 optional: it defaults to the traceback of the exception that is
2834 currently being handled (is mandatory to be in the middle of an
2835 exception, otherwise it raises ValueError).

2916-----------------
2917
Fred Drakea8ee94b2008-03-01 02:45:07 +00002918- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002919 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002921- Issue #2067: file.__exit__() now calls subclasses' close() method.
2922
2923- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002924
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002925- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002926 issue 215555 for a discussion.
2927
Eric Smitha73fbe72008-02-23 03:09:44 +00002928- Added the future_builtins module, which contains hex() and oct().
2929 These are the PEP 3127 version of these functions, designed to be
2930 compatible with the hex() and oct() builtins from Python 3.0. They
2931 differ slightly in their output formats from the existing, unchanged
2932 Python 2.6 builtins. The expected usage of the future_builtins
2933 module is:
2934 from future_builtins import hex, oct
2935
Eric Smith7ef40bf2008-02-20 23:34:22 +00002936- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2937 exponents for exponents with absolute value < 100. Follows C99
2938 standard. This is a change on Windows, which would use 3 digits.
2939 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2940 so that any alterations it does to the resulting string will be
2941 available in stringlib/formatter.h (for float.__format__).
2942
Eric Smith5a3c1352008-02-19 13:21:56 +00002943- Implemented PEP 3101, Advanced String Formatting. This adds a new
2944 builtin format(); a format() method for str and unicode; a
2945 __format__() method to object, str, unicode, int, long, float, and
2946 datetime; the class string.Formatter; and the C API
2947 PyObject_Format().
2948
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- Fixed several potential crashes, all caused by specially crafted
2950 __del__ methods exploiting objects in temporarily inconsistent
2951 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002952
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002953- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002954 prevent a possible crash: an Abstract Base Class would try to access
2955 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002956
Georg Brandl3ee81df2008-05-17 18:14:43 +00002957- Fixed repr() and str() of complex numbers with infinity or nan as
2958 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002959
Georg Brandl3ee81df2008-05-17 18:14:43 +00002960- Clear all free lists during a gc.collect() of the highest generation
2961 in order to allow pymalloc to free more arenas. Python may give back
2962 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002963
Georg Brandl3ee81df2008-05-17 18:14:43 +00002964- Issue #2045: Fix an infinite recursion triggered when printing a
2965 subclass of collections.defaultdict, if its default_factory is set
2966 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002967
Christian Heimesf75dbef2008-02-08 00:11:31 +00002968- Fixed a minor memory leak in dictobject.c. The content of the free
2969 list was not freed on interpreter shutdown.
2970
Georg Brandl3ee81df2008-05-17 18:14:43 +00002971- Limit free list of method and builtin function objects to 256
2972 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002973
Georg Brandl3ee81df2008-05-17 18:14:43 +00002974- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2975 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002976 to compact the internal free lists of pre-allocted ints and floats.
2977
Georg Brandl3ee81df2008-05-17 18:14:43 +00002978- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2979 calls. Python expected the return type int but the fork familie
2980 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002981
Georg Brandl3ee81df2008-05-17 18:14:43 +00002982- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2983 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002984
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2986 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002987

Georg Brandl3ee81df2008-05-17 18:14:43 +00002991- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2992 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002993
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994- Patch #1473257: generator objects gain a gi_code attribute. This is
2995 the same object as the func_code attribute of the function that
2996 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Issue #1920: "while 0" statements were completely removed by the
2999 compiler, even in the presence of an "else" clause, which is
3000 supposed to be run when the condition is false. Now the compiler
3001 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003002
Guido van Rossumeead05f2008-01-24 18:21:02 +00003003- A few crashers fixed: weakref_in_del.py (issue #1377858);
3004 loosing_dict_ref.py (issue #1303614, test67.py);
3005 borrowed_ref_[34].py (not in tracker).
3006
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003007- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003008 suppressed while an extension is loaded by calling SetErrorMode in
3009 dynload_win.c. The error is still reported properly.
3010
Georg Brandl3ee81df2008-05-17 18:14:43 +00003011- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003012 several extension methods and modules do not work without unicode
3013 support.
3014
Georg Brandl26543b12008-01-21 18:36:51 +00003015- Issue #1882: when compiling code from a string, encoding cookies in the
3016 second line of code were not always recognized correctly.
3017
Georg Brandl14404b62008-01-19 19:27:05 +00003018- Issue #1679: "0x" was taken as a valid integer literal.
3019
Georg Brandl6caad7d2008-01-26 14:19:22 +00003020- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003021 added.
3022
Christian Heimesc94e2b52008-01-14 04:13:37 +00003023- sys.float_info / PyFloat_GetInfo: The floating point information
3024 object was converted from a dict to a specialized structseq object.
3025
Georg Brandl3ee81df2008-05-17 18:14:43 +00003026- Patch #1816: Added sys.flags structseq. It exposes the status of
3027 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003028
Georg Brandl3ee81df2008-05-17 18:14:43 +00003029- Objects/structseq.c: Implemented new structseq representation. The
3030 patch makes structseqs (e.g. the return value of os.stat) more
3031 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003032
Georg Brandl3ee81df2008-05-17 18:14:43 +00003033- Patch #1700288: added a type attribute cache that caches method
3034 accesses, resulting in speedups in heavily object-oriented code.

3042 envvar and sys.dont_write_bytecode attribute. All these can be set
3043 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003044
Georg Brandl3ee81df2008-05-17 18:14:43 +00003045- Improve some exception messages when Windows fails to load an
3046 extension module. Now we get for example '%1 is not a valid Win32
3047 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003048

Georg Brandl3ee81df2008-05-17 18:14:43 +00003058- Compiler now generates simpler and faster code for dictionary
3059 literals. The oparg for BUILD_MAP now indicates an estimated
3060 dictionary size. There is a new opcode, STORE_MAP, for adding
3061 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003105- The enumerate() builtin function is no longer bounded to sequences

Georg Brandl3ee81df2008-05-17 18:14:43 +00003109- Issue #1686386: Tuple's tp_repr did not take into account the
3110 possibility of having a self-referential tuple, which is possible
3111 from C code. Nor did object's tp_str consider that a type's tp_str
3112 could do something that could lead to an inifinite recursion.
3113 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3114 issues.

3117 'print' statement to write to a file since the GIL was not released
3118 as needed. Now PyObject_Print() does the right thing along with

3181
Guido van Rossum143b5642007-03-23 04:58:42 +00003182- Bug #1683368: The object.__init__() and object.__new__() methods are
3183 now stricter in rejecting excess arguments. The only time when
3184 either allows excess arguments is when it is not overridden and the
3185 other one is. For backwards compatibility, when both are
3186 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003187 warning later). Also, type.__init__() insists on the same signature
3188 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003190- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3191 object to complex using its __complex__() method before falling back
3192 to the __float__() method. Therefore, the functions in the cmath
3193 module now can operate on objects that define a __complex__()
3194 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003212- Bug #1678647: write a newline after printing an exception in any
3213 case, even when converting the value to a string failed.
3214
Georg Brandl871f1bc2007-03-12 13:17:36 +00003215- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003216 its argument, if it exists. If not, it will work like before. This
3217 allows customizing the output of dir() in the presence of a
3218 __getattr__().

3228 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003230- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003231 makes the filenames the warning module prints much more sensible
3232 when a PYTHONSTARTUP file is used.

3247
Georg Brandl3ee81df2008-05-17 18:14:43 +00003248- When printing an unraisable error, don't print exceptions. before

3816
Georg Brandl92a6bae2007-03-13 17:43:32 +00003817- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003818 are set for invalid interpolation sequences that would lead to
3819 errors on reading back those values.

3875 TestCase and TestSuite subclasses (not instances) are no longer
3876 accepted in TestSuite.addTest(). This should cause no
3877 incompatibility since it never made sense with ordinary subclasses
3878 -- the failure just occurred later, with a more cumbersome
3879 exception.

4163 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004164
Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004166 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004168 does not claim to support starttls. Adds the

Raymond Hettinger12e94202007-11-07 01:13:09 +00004253

Georg Brandl3ee81df2008-05-17 18:14:43 +00004268 time so that opening a database previously created with the DB_DUP
4269 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4270 opens. Specifically: dictionary assignment to a DB object will
4271 replace all values for a given key when the database allows
4272 duplicate values. DB users should use DB.put(k, v) when they want

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004552- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004553 periodic threadstate and signal checking in tight loops. By
4554 default, this option is turned-off. It should only be enabled in
4555 debugged, performance critical applications.

4607
Georg Brandl3ee81df2008-05-17 18:14:43 +00004608- Unified naming convention for free lists and their limits. All free
4609 lists in Object/ are named ``free_list``, the counter ``numfree``
4610 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4611 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004612
Georg Brandl3ee81df2008-05-17 18:14:43 +00004613- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4614 to ``PyTuple_SetItem``, it can be used to populate a brand new
4615 frozenset; but it does not steal a reference to the added item.

4627
Georg Brandl3ee81df2008-05-17 18:14:43 +00004628- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4629 of w# format code incorrectly truncated the length to an int, even
4630 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4631 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004632

4653
4654- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4655 outside of pystate.c and should not be necessary.
4656
Georg Brandl3ee81df2008-05-17 18:14:43 +00004657- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4658 absolute imports. In earlier versions they might have used relative
4659 imports under some conditions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004661- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4662 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004663
Georg Brandl3ee81df2008-05-17 18:14:43 +00004664- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004689- Removed the macfs module. It had been deprecated since Python 2.5.
4690 This lead to the deprecation of macostools.touched() as it relied
4691 solely on macfs and was a no-op under OS X.
