119 statement and correctly lookup the __enter__ and __exit__ special methods.
120
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000121- Issue #5829: complex("1e500") no longer raises OverflowError. This
122 makes it consistent with float("1e500") and interpretation of real

133 (1) inf and nan strings with trailing whitespace were incorrectly
134 rejected; (2) parsing of strings representing infinities and nans
135 was locale aware; and (3) the interpretation of fromhex('-nan')
136 didn't match that of float('-nan').
137
Eric Smitha985a3a2009-05-05 18:26:08 +0000138- Issue #5920: For float.__format__, change the behavior with the
139 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
140 to be like 'g' but with at least one decimal point and with a
141 default precision of 12. Previously, the behavior the same but with
142 a default precision of 6. This more closely matches str(), and
143 reduces surprises when adding alignment flags to the empty
144 presentation type. This also affects the new complex.__format__ in
145 the same way.
146
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000147- Issue #5890: in subclasses of 'property' the __doc__ attribute was

156
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000157- Issue #5864: Fix empty format code formatting for floats so that it

170
Mark Dickinson95bc9802009-04-24 12:46:53 +0000171- Issue #5816: complex(repr(z)) now recovers z exactly, even when
172 z involves nans, infs or negative zeros.
173
Eric Smithaca19e62009-04-22 13:29:05 +0000174- Implement PEP 378, Format Specifier for Thousands Separator, for
175 floats, ints, and longs.
176
177- Issue #5515: 'n' formatting for ints, longs, and floats handles
178 leading zero formatting poorly.
179
180- Issue #5772: For float.__format__, don't add a trailing ".0" if
181 we're using no type code and we have an exponent.
182

187 some builtin types.
188
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000189- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000190 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000191
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000192- Issue #5759: float() didn't call __float__ on str subclasses.
193
Georg Brandl3c4a5462009-04-12 12:08:12 +0000194- Issue #5704: the "-3" command-line option now implies "-t".

210 untrackable objects are not tracked by the garbage collector. This can
211 reduce the size of collections and therefore the garbage collection overhead
212 on long-running programs, depending on their particular use of datatypes.
213
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000214- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
215 improve its performance. Long divisions and remainder operations
216 are now between 50% and 150% faster.
217
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000218- Issue #4258: Make it possible to use base 2**30 instead of base
219 2**15 for the internal representation of integers, for performance
220 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
221 --enable-big-digits option to configure, which overrides the
222 default. Add sys.long_info structseq to provide information about
223 the internal format.
224
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000225- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
226 result traceback.__members__ no longer exists.)
227
Mark Dickinson6b265f12009-03-18 16:07:26 +0000228- Issue #4474: PyUnicode_FromWideChar now converts characters outside
229 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

231
Eric Smith6f42edb2009-03-14 11:57:26 +0000232- Issue #5237: Allow auto-numbered fields in str.format(). For
233 example: '{} {}'.format(1, 2) == '1 2'.
234
Brett Cannon6c4cff02009-03-11 04:51:06 +0000235- Issue #3652: Make the 'line' argument for warnings.showwarning() a
236 requirement. Means the DeprecationWarning from Python 2.6 can go away.
237

243 for ints and longs.
244
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000245- Issue #5260: Long integers now consume less memory: average
246 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
247 on a 64-bit system.
248
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000249- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
250 rotating the object pointer by 4 bits to the right.
251
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000252- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

254
Benjamin Petersone18ef192009-01-20 14:21:16 +0000255- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
256
Georg Brandl29c6a282009-04-05 20:23:13 +0000257- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000258 were suppressing all exceptions. These include list(), filter(), map(),
259 zip(), and bytearray().
260
Benjamin Peterson596d3062009-01-19 15:42:23 +0000261- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

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

331
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000332- Issue #4445: Replace "sizeof(PyStringObject)" with
333 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
334 str instances. On a typical machine this saves 3 bytes of memory
335 (on average) per string allocation.
336
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000337- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Vinay Sajip213faca2008-12-03 23:22:58 +0000347- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000348 method on file objects with closefd=False. The file descriptor is still
349 kept open but the file object behaves like a closed file. The ``FileIO``
350 object also got a new readonly attribute ``closefd``.
351
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000352- Issue #4348: Some bytearray methods returned that didn't cause any change to

366
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000367- Issue #4209: Enabling unicode_literals and the print_function in the same
368 __future__ import didn't work.
369
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000370- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000371 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000373- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
374 returned a path longer than MAX_PATH. (But It's doubtful this code path is
375 really executed because I cannot move to such directory on win2k)
376
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000377- Issue #4069: When set.remove(element) is used with a set element, the element
378 is temporarily replaced with an equivalent frozenset. But the eventual
379 KeyError would always report the empty frozenset([]) as the missing key. Now
380 it correctly refers to the initial element.
381
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000382- Issue #4509: Various issues surrounding resize of bytearray objects to

398 returned them on 64bit platforms.
399
Walter Dörwalded960ac2009-05-03 22:36:33 +0000400- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
401 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
402 step. This avoids problems with counting UTF-8 bytes that ignores the effect
403 of using the replace error handler in PyUnicode_DecodeUTF8().
404
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000405- Issue #3739: The unicode-internal encoder now reports the number of characters

Mark Dickinson5fd3af22009-07-07 15:08:28 +00001421- Issue #1523: Remove deprecated overflow wrapping for struct.pack
1422 with an integer format code ('bBhHiIlLqQ'). Packing an out-of-range
1423 integer now consistently raises struct.error.

Mark Dickinson463dc4b2009-07-05 10:01:24 +00001425- Issues #1530559, #1741130: Fix various struct.pack inconsistencies
1426 for the integer formats ('bBhHiIlLqQ'). In the following, '*'
1427 represents any of '=', '<', '>'.
1428
1429 - Packing a float now always gives a Deprecation Warning.
1430 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
1431
1432 - If x is not an int, long or float, then packing x will always
1433 result in struct.error. Previously an x with an __int__ method
1434 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1435 ,'*i', '*l', and an x with a __long__ method could be packed by
1436 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
1437 TypeError used to be raised (with a confusing error message) for
1438 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

1492 it easy to import both normal and optimised versions of modules.
1493 test_heapq and test_warnings have been adjusted to use it, tests for
1494 other modules with both C and Python implementations in the stdlib

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001601- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1602
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001603- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1604 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1605 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1606 ``printf`` function, whereas PyString_FromFormat has an independent
1607 implementation and uses "%zd" on all platforms for size_t values.
1608 This makes a difference on win64, where ``printf`` needs "%Id" to display
1609 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001611- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1615 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001626 was correctly parsed but parsing of subsequent arguments failed.
1627
Vinay Sajip35e3b032008-09-01 14:33:59 +00001628- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001629 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1630 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1631 when given a tuple of classes as second argument, were looking up
1632 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1633 type object.
1634
Neal Norwitz18aa3882008-08-24 05:04:52 +00001635- Fix crashes on memory allocation failure found with failmalloc.

1730
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001731- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001772What's New in Python 2.6 beta 3?
1773================================
1774
Barry Warsaw07a4a382008-08-21 01:15:08 +00001775*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001776
1777Core and Builtins
1778-----------------
1779
Guido van Rossumf8402962008-08-20 15:01:50 +00001780- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1781 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1782 extensions do not automatically benefit from the class attribute
1783 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1784 to their tp_flags field if they care. This is a backwards
1785 compatibility feature; in 3.0, all types will use the cache by
1786 default.
1787
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001788- Keyword arguments can now follow starred arguments. (``f(a, *args,
1789 keyword=23)`` is now valid syntax.)
1790
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001791- ctypes function pointers that are COM methods have a boolean True
1792 value again.
1793
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001794- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1795 by denying s# to parse objects that have a releasebuffer procedure,
1796 and introducing s*.
1797
Georg Brandl1e13ea92008-08-11 09:07:59 +00001798- Issue #3537: Fix an assertion failure when an empty but presized dict
1799 object was stored in the freelist.
1800
Mark Dickinsonb6467572008-08-04 21:30:09 +00001801- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1802 ValueError consistently across platforms.
1803
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001804- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1805 (64bit Unix, for example), unichr() would truncate its argument and return
1806 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1807
Neal Norwitze7d8be82008-07-31 17:17:14 +00001808- Apply security patches from Apple.
1809
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001810- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1811 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1812
Antoine Pitrou92f82162008-07-25 22:22:08 +00001813- Issue #1819: function calls with several named parameters are now on
1814 average 35% faster (as measured by pybench).
1815
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001816- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1817 the python debugger steps into a class statement: the free variables (local
1818 variables defined in an outer scope) would be deleted from the outer scope.
1819
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001820- Issue #2620: Overflow checking when allocating or reallocating memory
1821 was not always being done properly in some python types and extension
1822 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1823 all been updated to perform better checks and places in the code that
1824 would previously leak memory on the error path when such an allocation
1825 failed have been fixed.
1826
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001827Library
1828-------
1829
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001830- Issue #3612: Added some missing basic types in ctypes.wintypes.
1831
Benjamin Petersone977ad42008-08-20 01:42:01 +00001832- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1833 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1834
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001835- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1836 version reported by these tools does not necessarily follow the python
1837 version numbering scheme, so the module is less strict when parsing it.
1838
Nick Coghlanf70385a2008-08-18 12:42:46 +00001839- Issue #2235: Added Py3k warnings for types which will become unhashable
1840 under the stricter __hash__ inheritance rules in 3.0. Several types
1841 which did not meet the rules for hash invariants and were already
1842 unhashable in 3.0 have now been explicitly flagged as unhashable in
1843 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1844 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1845
Brett Cannon88f801d2008-08-18 00:46:22 +00001846- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1847 imported into the module but exposed as part of the module's API.
1848

1854
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001855- Issue #3575: Incremental decoder's decode function now takes bytearray
1856 by using 's*' instead of 't#'.
1857
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001858- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001859 fails unicode conversion on 2nd parameter. (windows only)
1860
Facundo Batista94f243a2008-08-17 03:38:39 +00001861- Issue 2464. urllib2 now supports a malformation in the URL received
1862 in a redirect.
1863
Brett Cannonabe423e2008-08-16 21:47:07 +00001864- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001865 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001866
Facundo Batistaeb90b782008-08-16 14:44:07 +00001867- Issue #2776: fixed small issue when handling an URL with double slash
1868 after a 302 response in the case of not going through a proxy.
1869
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001870- Issue #2676: in the email package, content-type parsing was hanging on
1871 pathological input because of quadratic or exponential behaviour of a
1872 regular expression.
1873
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001874- Issue #3476: binary buffered reading through the new "io" library is now
1875 thread-safe.
1876
Brett Cannonbf3157b2008-08-14 05:00:03 +00001877- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1878 since mimetools itself is deprecated. Because modules are cached, all
1879 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1880
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001881- Issue #3134: shutil referenced undefined WindowsError symbol.
1882
Robert Schuppenies14646332008-08-10 11:01:53 +00001883- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1884 menu entries were not deleted.
1885
Brett Cannon83e81842008-08-09 23:30:55 +00001886- Copied the implementation of reduce() to _functools.reduce() to have a
1887 version that did not raise a DeprecationWarning under -3.
1888
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001889- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1890 a MemoryError rather than silently stop the iteration.
1891
Guido van Rossum59ce9012008-08-09 14:55:34 +00001892- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1893 to _sre.compile() will now be rejected. This should not affect anybody
1894 since the re.compile() function never generates invalid re-bytecode.
1895
Skip Montanaroa032bf42008-08-08 22:52:51 +00001896- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1897 upon first access it can be automatically initialized from the csv file if
1898 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00001900- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1901 the reload() built-in has been removed.
1902
Brett Cannon7e30b672008-08-04 21:52:25 +00001903- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001904 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1912 raised an AttributeError.
1913

Antoine Pitroude781a42008-08-09 12:43:23 +00001915 asking for a specific length. This problem only affected files opened
1916 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001917

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001941- Issue #3394: zipfile.writestr sets external attributes when passed a
1942 file name rather than a ZipInfo instance, so files are extracted with
1943 mode 0600 rather than 000 under Unix.
1944
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001945- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1961 coverage of the lookup process for special methods. The disclaimers
1962 regarding lack of coverage of new-style classes have also been
1963 removed, since the coverage is now fairly reasonable.

1972-----------------
1973
Georg Brandl3e483f62008-07-16 22:57:41 +00001974- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1975 its methods now allow for items objects that can be converted to
1976 an integer using operator.index().
1977
Mark Dickinson64b7e502008-07-16 09:40:03 +00001978- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1979 produced a ValueError instead of giving the correct float.
1980
Eric Smitha5fa5a22008-07-16 00:11:49 +00001981- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1982 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1983
Mark Dickinson7103aa42008-07-15 19:08:33 +00001984- Issue #3008: the float type has a new instance method 'float.hex'
1985 and a new class method 'float.fromhex' to convert floating-point
1986 numbers to and from hexadecimal strings, respectively.
1987
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001988- Issue #2235: __hash__ is once again inherited by default. To allow
1989 collections.Hashable to remain meaningful in the presence of the
1990 default hash implementation (object.__hash__), it is now possible
1991 to explicit block inheritance of hash by setting __hash__=None at
1992 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1993 level.
1994
Nick Coghlanb028f502008-07-13 14:52:36 +00001995- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1996 the parent module cannot be found while performing an absolute import.
1997 This means that an incorrectly defined __package__ attribute will
1998 now only prevent relative imports in that module rather than causing
1999 all imports from that module to fail.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002472 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002473
2474 This is controlled by the configure argument ``--with-universal-archs``:

2521 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002534- Issue #1631171: Re-implement the 'warnings' module in C (the
2535 original Python code has been kept as backup). This will allow for
2536 using the 'warning's machinery in such places as the parser where
2537 use of pure Python code is not possible. Both the ``showarning()``
2538 and ``formatwarning()`` gain an optional 'line' argument which is
2539 not called by default for backwards-compatibility reasons. Setting
2540 ``warnings.showwarning()`` to an implementation that lacks support
2541 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002604- Issue #2550: The approach used by client/server code for obtaining
2605 ports to listen on in network-oriented tests has been refined in an
2606 effort to facilitate running multiple instances of the entire
2607 regression test suite in parallel without issue.
2608 test_support.bind_port() has been fixed such that it will always
2609 return a unique port -- which wasn't always the case with the
2610 previous implementation, especially if socket options had been set
2611 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2612 new implementation of bind_port() will actually raise an exception
2613 if it is passed an AF_INET/SOCK_STREAM socket with either the
2614 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2615 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2616 the socket it's been passed. This currently only applies to
2617 Windows. This option prevents any other sockets from binding to the
2618 host/port we've bound to, thus removing the possibility of the
2619 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2620 when a second SOCK_STREAM socket binds and accepts to a host/port
2621 that's already been bound by another socket. The optional preferred
2622 port parameter to bind_port() has been removed. Under no
2623 circumstances should tests be hard coding ports!
2624
2625 test_support.find_unused_port() has also been introduced, which will
2626 pass a temporary socket object to bind_port() in order to obtain an
2627 unused port. The temporary socket object is then closed and
2628 deleted, and the port is returned. This method should only be used
2629 for obtaining an unused port in order to pass to an external program
2630 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2631 a parameter to a server-oriented class that doesn't give you direct
2632 access to the underlying socket used.
2633
2634 Finally, test_support.HOST has been introduced, which should be used
2635 for the host argument of any relevant socket calls (i.e. bind and
2636 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002637
2638 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002639 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002640 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2641 test_asynchat and test_socket_ssl.
2642
Georg Brandl3ee81df2008-05-17 18:14:43 +00002643 It is now possible for multiple instances of the regression test
2644 suite to run in parallel without issue.

2912
Fred Drakea8ee94b2008-03-01 02:45:07 +00002913- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002914 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002916- Issue #2067: file.__exit__() now calls subclasses' close() method.
2917
2918- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002919
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002920- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002921 issue 215555 for a discussion.
2922
Eric Smitha73fbe72008-02-23 03:09:44 +00002923- Added the future_builtins module, which contains hex() and oct().
2924 These are the PEP 3127 version of these functions, designed to be
2925 compatible with the hex() and oct() builtins from Python 3.0. They
2926 differ slightly in their output formats from the existing, unchanged
2927 Python 2.6 builtins. The expected usage of the future_builtins
2928 module is:
2929 from future_builtins import hex, oct
2930
Eric Smith7ef40bf2008-02-20 23:34:22 +00002931- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2932 exponents for exponents with absolute value < 100. Follows C99
2933 standard. This is a change on Windows, which would use 3 digits.
2934 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2935 so that any alterations it does to the resulting string will be
2936 available in stringlib/formatter.h (for float.__format__).
2937
Eric Smith5a3c1352008-02-19 13:21:56 +00002938- Implemented PEP 3101, Advanced String Formatting. This adds a new
2939 builtin format(); a format() method for str and unicode; a
2940 __format__() method to object, str, unicode, int, long, float, and
2941 datetime; the class string.Formatter; and the C API
2942 PyObject_Format().
2943
Georg Brandl3ee81df2008-05-17 18:14:43 +00002944- Fixed several potential crashes, all caused by specially crafted
2945 __del__ methods exploiting objects in temporarily inconsistent
2946 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002947
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002948- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949 prevent a possible crash: an Abstract Base Class would try to access
2950 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002951

Georg Brandl3ee81df2008-05-17 18:14:43 +00002955- Clear all free lists during a gc.collect() of the highest generation
2956 in order to allow pymalloc to free more arenas. Python may give back
2957 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002958
Georg Brandl3ee81df2008-05-17 18:14:43 +00002959- Issue #2045: Fix an infinite recursion triggered when printing a
2960 subclass of collections.defaultdict, if its default_factory is set
2961 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002962
Christian Heimesf75dbef2008-02-08 00:11:31 +00002963- Fixed a minor memory leak in dictobject.c. The content of the free
2964 list was not freed on interpreter shutdown.
2965
Georg Brandl3ee81df2008-05-17 18:14:43 +00002966- Limit free list of method and builtin function objects to 256
2967 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002968
Georg Brandl3ee81df2008-05-17 18:14:43 +00002969- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2970 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002971 to compact the internal free lists of pre-allocted ints and floats.
2972
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2974 calls. Python expected the return type int but the fork familie
2975 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002976
Georg Brandl3ee81df2008-05-17 18:14:43 +00002977- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2978 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002979
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2981 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002982

Georg Brandl3ee81df2008-05-17 18:14:43 +00002986- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2987 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002988
Georg Brandl3ee81df2008-05-17 18:14:43 +00002989- Patch #1473257: generator objects gain a gi_code attribute. This is
2990 the same object as the func_code attribute of the function that
2991 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002992
Georg Brandl3ee81df2008-05-17 18:14:43 +00002993- Issue #1920: "while 0" statements were completely removed by the
2994 compiler, even in the presence of an "else" clause, which is
2995 supposed to be run when the condition is false. Now the compiler
2996 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002997
Guido van Rossumeead05f2008-01-24 18:21:02 +00002998- A few crashers fixed: weakref_in_del.py (issue #1377858);
2999 loosing_dict_ref.py (issue #1303614, test67.py);
3000 borrowed_ref_[34].py (not in tracker).
3001
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003002- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003003 suppressed while an extension is loaded by calling SetErrorMode in
3004 dynload_win.c. The error is still reported properly.
3005
Georg Brandl3ee81df2008-05-17 18:14:43 +00003006- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003007 several extension methods and modules do not work without unicode
3008 support.
3009
Georg Brandl26543b12008-01-21 18:36:51 +00003010- Issue #1882: when compiling code from a string, encoding cookies in the
3011 second line of code were not always recognized correctly.
3012
Georg Brandl14404b62008-01-19 19:27:05 +00003013- Issue #1679: "0x" was taken as a valid integer literal.
3014
Georg Brandl6caad7d2008-01-26 14:19:22 +00003015- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003016 added.
3017
Christian Heimesc94e2b52008-01-14 04:13:37 +00003018- sys.float_info / PyFloat_GetInfo: The floating point information
3019 object was converted from a dict to a specialized structseq object.
3020
Georg Brandl3ee81df2008-05-17 18:14:43 +00003021- Patch #1816: Added sys.flags structseq. It exposes the status of
3022 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003023
Georg Brandl3ee81df2008-05-17 18:14:43 +00003024- Objects/structseq.c: Implemented new structseq representation. The

3026 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003027
Georg Brandl3ee81df2008-05-17 18:14:43 +00003028- Patch #1700288: added a type attribute cache that caches method

3038 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003039
Georg Brandl3ee81df2008-05-17 18:14:43 +00003040- Improve some exception messages when Windows fails to load an
3041 extension module. Now we get for example '%1 is not a valid Win32
3042 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003043

Christian Heimes0a8143f2007-12-18 23:22:54 +00003049- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050 and INF. float("nan"), float("inf") and float("-inf") now work on
3051 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003052
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053- Compiler now generates simpler and faster code for dictionary
3054 literals. The oparg for BUILD_MAP now indicates an estimated
3055 dictionary size. There is a new opcode, STORE_MAP, for adding
3056 entries to the dictionary.

3099
Georg Brandl3ee81df2008-05-17 18:14:43 +00003100- The enumerate() builtin function is no longer bounded to sequences
3101 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3102 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003103
Georg Brandl3ee81df2008-05-17 18:14:43 +00003104- Issue #1686386: Tuple's tp_repr did not take into account the
3105 possibility of having a self-referential tuple, which is possible
3106 from C code. Nor did object's tp_str consider that a type's tp_str
3107 could do something that could lead to an inifinite recursion.
3108 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3109 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003111- Issue #1164: It was possible to trigger deadlock when using the
3112 'print' statement to write to a file since the GIL was not released
3113 as needed. Now PyObject_Print() does the right thing along with
3114 various tp_print implementations of the built-in types and those in
3115 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00003124- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003125 PyObject_Call() never calling back out to Python code to trigger
3126 recursion depth updates/checks. Required the creation of a static

3153
Collin Winter62903052007-05-18 23:11:24 +00003154- except clauses may now be spelled either "except E, target:" or

3156 with Python 3.0.

3162
Vinay Sajip8549ce32007-05-06 17:53:37 +00003163- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003164 setting a plain string, ie don't expand to single letter identifiers.
3165
Raymond Hettinger13936692007-04-11 18:40:58 +00003166- Request #1191699: Slices can now be pickled.
3167
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003168- Request #1193128: str.translate() now allows a None argument for

3176
Guido van Rossum143b5642007-03-23 04:58:42 +00003177- Bug #1683368: The object.__init__() and object.__new__() methods are
3178 now stricter in rejecting excess arguments. The only time when
3179 either allows excess arguments is when it is not overridden and the
3180 other one is. For backwards compatibility, when both are
3181 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003182 warning later). Also, type.__init__() insists on the same signature
3183 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3186 object to complex using its __complex__() method before falling back
3187 to the __float__() method. Therefore, the functions in the cmath
3188 module now can operate on objects that define a __complex__()
3189 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003207- Bug #1678647: write a newline after printing an exception in any
3208 case, even when converting the value to a string failed.
3209
Georg Brandl871f1bc2007-03-12 13:17:36 +00003210- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003211 its argument, if it exists. If not, it will work like before. This
3212 allows customizing the output of dir() in the presence of a
3213 __getattr__().

3222 parthensized forms. This means complex(repr(x)) now works instead of
3223 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003224
Georg Brandlaa2321b2007-03-07 00:40:28 +00003225- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226 makes the filenames the warning module prints much more sensible
3227 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003240- Patch #1674228: when assigning a slice (old-style), check for the
3241 sq_ass_slice instead of the sq_slice slot.
3242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- When printing an unraisable error, don't print exceptions. before

3811
Georg Brandl92a6bae2007-03-13 17:43:32 +00003812- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003813 are set for invalid interpolation sequences that would lead to

3870 TestCase and TestSuite subclasses (not instances) are no longer
3871 accepted in TestSuite.addTest(). This should cause no

3873 -- the failure just occurred later, with a more cumbersome
3874 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004155- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4156 with RFC 3207 and forgets any knowledge obtained from the server not
4157 obtained from the TLS negotiation itself. Patch contributed by Bill
4158 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004159
Georg Brandl3ee81df2008-05-17 18:14:43 +00004160- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004161 that the SMTP.starttls() caller no longer needs to call ehlo()
4162 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004163 does not claim to support starttls. Adds the
4164 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4245 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4246 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004248

Georg Brandl3ee81df2008-05-17 18:14:43 +00004263 time so that opening a database previously created with the DB_DUP
4264 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4265 opens. Specifically: dictionary assignment to a DB object will
4266 replace all values for a given key when the database allows
4267 duplicate values. DB users should use DB.put(k, v) when they want
4268 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004269

4275 characters with ASCII value less than 32. Also, it correctly quotes
4276 dots only if they occur on a single line, as opposed to the previous
4277 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004547- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004548 periodic threadstate and signal checking in tight loops. By
4549 default, this option is turned-off. It should only be enabled in
4550 debugged, performance critical applications.

4601-----
4602
Georg Brandl3ee81df2008-05-17 18:14:43 +00004603- Unified naming convention for free lists and their limits. All free
4604 lists in Object/ are named ``free_list``, the counter ``numfree``
4605 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4606 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004607
Georg Brandl3ee81df2008-05-17 18:14:43 +00004608- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4609 to ``PyTuple_SetItem``, it can be used to populate a brand new
4610 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004611

4622
Georg Brandl3ee81df2008-05-17 18:14:43 +00004623- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4624 of w# format code incorrectly truncated the length to an int, even
4625 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4626 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004627
Georg Brandl3ee81df2008-05-17 18:14:43 +00004628- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4648
4649- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4650 outside of pystate.c and should not be necessary.
4651
Georg Brandl3ee81df2008-05-17 18:14:43 +00004652- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4653 absolute imports. In earlier versions they might have used relative
4654 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004655
Georg Brandl3ee81df2008-05-17 18:14:43 +00004656- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4657 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004658
Georg Brandl3ee81df2008-05-17 18:14:43 +00004659- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004684- Removed the macfs module. It had been deprecated since Python 2.5.
4685 This lead to the deprecation of macostools.touched() as it relied
4686 solely on macfs and was a no-op under OS X.
