116 statement and correctly lookup the __enter__ and __exit__ special methods.
117
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000118- Issue #5829: complex("1e500") no longer raises OverflowError. This
119 makes it consistent with float("1e500") and interpretation of real

130 (1) inf and nan strings with trailing whitespace were incorrectly
131 rejected; (2) parsing of strings representing infinities and nans
132 was locale aware; and (3) the interpretation of fromhex('-nan')
133 didn't match that of float('-nan').
134
Eric Smitha985a3a2009-05-05 18:26:08 +0000135- Issue #5920: For float.__format__, change the behavior with the
136 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
137 to be like 'g' but with at least one decimal point and with a
138 default precision of 12. Previously, the behavior the same but with
139 a default precision of 6. This more closely matches str(), and
140 reduces surprises when adding alignment flags to the empty
141 presentation type. This also affects the new complex.__format__ in
142 the same way.
143
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000144- Issue #5890: in subclasses of 'property' the __doc__ attribute was

153
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000154- Issue #5864: Fix empty format code formatting for floats so that it

167
Mark Dickinson95bc9802009-04-24 12:46:53 +0000168- Issue #5816: complex(repr(z)) now recovers z exactly, even when
169 z involves nans, infs or negative zeros.
170
Eric Smithaca19e62009-04-22 13:29:05 +0000171- Implement PEP 378, Format Specifier for Thousands Separator, for
172 floats, ints, and longs.
173
174- Issue #5515: 'n' formatting for ints, longs, and floats handles
175 leading zero formatting poorly.
176
177- Issue #5772: For float.__format__, don't add a trailing ".0" if
178 we're using no type code and we have an exponent.
179

184 some builtin types.
185
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000186- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000187 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000188
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000189- Issue #5759: float() didn't call __float__ on str subclasses.
190
Georg Brandl3c4a5462009-04-12 12:08:12 +0000191- Issue #5704: the "-3" command-line option now implies "-t".

207 untrackable objects are not tracked by the garbage collector. This can
208 reduce the size of collections and therefore the garbage collection overhead
209 on long-running programs, depending on their particular use of datatypes.
210
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000211- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
212 improve its performance. Long divisions and remainder operations
213 are now between 50% and 150% faster.
214
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000215- Issue #4258: Make it possible to use base 2**30 instead of base
216 2**15 for the internal representation of integers, for performance
217 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
218 --enable-big-digits option to configure, which overrides the
219 default. Add sys.long_info structseq to provide information about
220 the internal format.
221

228
Eric Smith6f42edb2009-03-14 11:57:26 +0000229- Issue #5237: Allow auto-numbered fields in str.format(). For
230 example: '{} {}'.format(1, 2) == '1 2'.
231
Brett Cannon6c4cff02009-03-11 04:51:06 +0000232- Issue #3652: Make the 'line' argument for warnings.showwarning() a
233 requirement. Means the DeprecationWarning from Python 2.6 can go away.
234

243 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
244 on a 64-bit system.
245
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000246- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
247 rotating the object pointer by 4 bits to the right.
248
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000249- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

251
Benjamin Petersone18ef192009-01-20 14:21:16 +0000252- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
253
Georg Brandl29c6a282009-04-05 20:23:13 +0000254- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000255 were suppressing all exceptions. These include list(), filter(), map(),
256 zip(), and bytearray().
257
Benjamin Peterson596d3062009-01-19 15:42:23 +0000258- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

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

328
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000329- Issue #4445: Replace "sizeof(PyStringObject)" with
330 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
331 str instances. On a typical machine this saves 3 bytes of memory
332 (on average) per string allocation.
333
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000334- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Vinay Sajip213faca2008-12-03 23:22:58 +0000344- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000345 method on file objects with closefd=False. The file descriptor is still
346 kept open but the file object behaves like a closed file. The ``FileIO``
347 object also got a new readonly attribute ``closefd``.
348
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000349- Issue #4348: Some bytearray methods returned that didn't cause any change to

365 __future__ import didn't work.
366
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000367- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000368 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000370- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
371 returned a path longer than MAX_PATH. (But It's doubtful this code path is
372 really executed because I cannot move to such directory on win2k)
373
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000374- Issue #4069: When set.remove(element) is used with a set element, the element
375 is temporarily replaced with an equivalent frozenset. But the eventual
376 KeyError would always report the empty frozenset([]) as the missing key. Now
377 it correctly refers to the initial element.
378

395 returned them on 64bit platforms.
396
Walter Dörwalded960ac2009-05-03 22:36:33 +0000397- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
398 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
399 step. This avoids problems with counting UTF-8 bytes that ignores the effect
400 of using the replace error handler in PyUnicode_DecodeUTF8().
401
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000402- Issue #3739: The unicode-internal encoder now reports the number of characters

1415 Unicode category 'Nd' (Number, Decimal Digit). Previously it also
1416 matched characters with category 'No'.

Mark Dickinson5fd3af22009-07-07 15:08:28 +00001418- Issue #1523: Remove deprecated overflow wrapping for struct.pack
1419 with an integer format code ('bBhHiIlLqQ'). Packing an out-of-range
1420 integer now consistently raises struct.error.
1421
Mark Dickinson463dc4b2009-07-05 10:01:24 +00001422- Issues #1530559, #1741130: Fix various struct.pack inconsistencies
1423 for the integer formats ('bBhHiIlLqQ'). In the following, '*'
1424 represents any of '=', '<', '>'.
1425
1426 - Packing a float now always gives a Deprecation Warning.
1427 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
1428
1429 - If x is not an int, long or float, then packing x will always
1430 result in struct.error. Previously an x with an __int__ method
1431 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1432 ,'*i', '*l', and an x with a __long__ method could be packed by
1433 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
1434 TypeError used to be raised (with a confusing error message) for
1435 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

1489 it easy to import both normal and optimised versions of modules.
1490 test_heapq and test_warnings have been adjusted to use it, tests for
1491 other modules with both C and Python implementations in the stdlib

1599
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001600- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1601 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1602 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1603 ``printf`` function, whereas PyString_FromFormat has an independent
1604 implementation and uses "%zd" on all platforms for size_t values.
1605 This makes a difference on win64, where ``printf`` needs "%Id" to display
1606 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001608- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001623 was correctly parsed but parsing of subsequent arguments failed.
1624
Vinay Sajip35e3b032008-09-01 14:33:59 +00001625- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001626 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1627 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1628 when given a tuple of classes as second argument, were looking up
1629 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1630 type object.
1631
Neal Norwitz18aa3882008-08-24 05:04:52 +00001632- Fix crashes on memory allocation failure found with failmalloc.

1727
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001728- Issue #2975: When compiling several extension modules with Visual Studio 2008
1729 from the same python interpreter, some environment variables would grow
1730 without limit.
1731
Benjamin Peterson37346b22008-08-23 20:27:43 +00001732- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001769What's New in Python 2.6 beta 3?
1770================================
1771
Barry Warsaw07a4a382008-08-21 01:15:08 +00001772*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001773
1774Core and Builtins
1775-----------------
1776
Guido van Rossumf8402962008-08-20 15:01:50 +00001777- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1778 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1779 extensions do not automatically benefit from the class attribute
1780 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1781 to their tp_flags field if they care. This is a backwards
1782 compatibility feature; in 3.0, all types will use the cache by
1783 default.
1784
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001785- Keyword arguments can now follow starred arguments. (``f(a, *args,
1786 keyword=23)`` is now valid syntax.)
1787
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001788- ctypes function pointers that are COM methods have a boolean True
1789 value again.
1790
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001791- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1792 by denying s# to parse objects that have a releasebuffer procedure,
1793 and introducing s*.
1794
Georg Brandl1e13ea92008-08-11 09:07:59 +00001795- Issue #3537: Fix an assertion failure when an empty but presized dict
1796 object was stored in the freelist.
1797
Mark Dickinsonb6467572008-08-04 21:30:09 +00001798- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1799 ValueError consistently across platforms.
1800
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001801- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1802 (64bit Unix, for example), unichr() would truncate its argument and return
1803 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1804
Neal Norwitze7d8be82008-07-31 17:17:14 +00001805- Apply security patches from Apple.
1806
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001807- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1808 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1809
Antoine Pitrou92f82162008-07-25 22:22:08 +00001810- Issue #1819: function calls with several named parameters are now on
1811 average 35% faster (as measured by pybench).
1812
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001813- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1814 the python debugger steps into a class statement: the free variables (local
1815 variables defined in an outer scope) would be deleted from the outer scope.
1816
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001817- Issue #2620: Overflow checking when allocating or reallocating memory
1818 was not always being done properly in some python types and extension
1819 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1820 all been updated to perform better checks and places in the code that
1821 would previously leak memory on the error path when such an allocation
1822 failed have been fixed.
1823
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001824Library
1825-------
1826
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001827- Issue #3612: Added some missing basic types in ctypes.wintypes.
1828
Benjamin Petersone977ad42008-08-20 01:42:01 +00001829- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1830 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1831
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001832- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1833 version reported by these tools does not necessarily follow the python
1834 version numbering scheme, so the module is less strict when parsing it.
1835
Nick Coghlanf70385a2008-08-18 12:42:46 +00001836- Issue #2235: Added Py3k warnings for types which will become unhashable
1837 under the stricter __hash__ inheritance rules in 3.0. Several types
1838 which did not meet the rules for hash invariants and were already
1839 unhashable in 3.0 have now been explicitly flagged as unhashable in
1840 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1841 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1842
Brett Cannon88f801d2008-08-18 00:46:22 +00001843- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1844 imported into the module but exposed as part of the module's API.
1845

1847
Brett Cannon46225e72008-08-18 00:36:52 +00001848- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1851
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001852- Issue #3575: Incremental decoder's decode function now takes bytearray
1853 by using 's*' instead of 't#'.
1854
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001855- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001856 fails unicode conversion on 2nd parameter. (windows only)
1857
Facundo Batista94f243a2008-08-17 03:38:39 +00001858- Issue 2464. urllib2 now supports a malformation in the URL received
1859 in a redirect.
1860
Brett Cannonabe423e2008-08-16 21:47:07 +00001861- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001862 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001863
Facundo Batistaeb90b782008-08-16 14:44:07 +00001864- Issue #2776: fixed small issue when handling an URL with double slash
1865 after a 302 response in the case of not going through a proxy.
1866
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001867- Issue #2676: in the email package, content-type parsing was hanging on
1868 pathological input because of quadratic or exponential behaviour of a
1869 regular expression.
1870
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001871- Issue #3476: binary buffered reading through the new "io" library is now
1872 thread-safe.
1873
Brett Cannonbf3157b2008-08-14 05:00:03 +00001874- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1875 since mimetools itself is deprecated. Because modules are cached, all
1876 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1877
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001878- Issue #3134: shutil referenced undefined WindowsError symbol.
1879
Robert Schuppenies14646332008-08-10 11:01:53 +00001880- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1881 menu entries were not deleted.
1882
Brett Cannon83e81842008-08-09 23:30:55 +00001883- Copied the implementation of reduce() to _functools.reduce() to have a
1884 version that did not raise a DeprecationWarning under -3.
1885
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001886- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1887 a MemoryError rather than silently stop the iteration.
1888
Guido van Rossum59ce9012008-08-09 14:55:34 +00001889- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1890 to _sre.compile() will now be rejected. This should not affect anybody
1891 since the re.compile() function never generates invalid re-bytecode.
1892
Skip Montanaroa032bf42008-08-08 22:52:51 +00001893- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1894 upon first access it can be automatically initialized from the csv file if
1895 it wasn't initialized during instantiation.
1896
Brett Cannon3aa2a492008-08-06 22:28:09 +00001897- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1898 the reload() built-in has been removed.
1899
Brett Cannon7e30b672008-08-04 21:52:25 +00001900- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001901 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1909 raised an AttributeError.
1910

Antoine Pitroude781a42008-08-09 12:43:23 +00001912 asking for a specific length. This problem only affected files opened
1913 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001914
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001915- Issue #3449: Update decimal module to use most recent specification

1937
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001938- Issue #3394: zipfile.writestr sets external attributes when passed a
1939 file name rather than a ZipInfo instance, so files are extracted with
1940 mode 0600 rather than 000 under Unix.
1941
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001942- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1943 argument in python 2.5, this broke code that subclassed Popen to include its
1944 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1958 coverage of the lookup process for special methods. The disclaimers
1959 regarding lack of coverage of new-style classes have also been
1960 removed, since the coverage is now fairly reasonable.

1969-----------------
1970
Georg Brandl3e483f62008-07-16 22:57:41 +00001971- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1972 its methods now allow for items objects that can be converted to
1973 an integer using operator.index().
1974
Mark Dickinson64b7e502008-07-16 09:40:03 +00001975- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1976 produced a ValueError instead of giving the correct float.
1977
Eric Smitha5fa5a22008-07-16 00:11:49 +00001978- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1979 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1980
Mark Dickinson7103aa42008-07-15 19:08:33 +00001981- Issue #3008: the float type has a new instance method 'float.hex'
1982 and a new class method 'float.fromhex' to convert floating-point
1983 numbers to and from hexadecimal strings, respectively.
1984
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001985- Issue #2235: __hash__ is once again inherited by default. To allow
1986 collections.Hashable to remain meaningful in the presence of the
1987 default hash implementation (object.__hash__), it is now possible
1988 to explicit block inheritance of hash by setting __hash__=None at
1989 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1990 level.
1991
Nick Coghlanb028f502008-07-13 14:52:36 +00001992- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1993 the parent module cannot be found while performing an absolute import.
1994 This means that an incorrectly defined __package__ attribute will
1995 now only prevent relative imports in that module rather than causing
1996 all imports from that module to fail.
1997
Nick Coghlan14ff9942008-07-08 14:21:42 +00001998- Issue #2517: Allow unicode messages in Exceptions again by correctly

Georg Brandl5cc774e2008-06-11 20:28:06 +00002469 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002470

Georg Brandl3ee81df2008-05-17 18:14:43 +00002531- Issue #1631171: Re-implement the 'warnings' module in C (the
2532 original Python code has been kept as backup). This will allow for
2533 using the 'warning's machinery in such places as the parser where
2534 use of pure Python code is not possible. Both the ``showarning()``
2535 and ``formatwarning()`` gain an optional 'line' argument which is
2536 not called by default for backwards-compatibility reasons. Setting
2537 ``warnings.showwarning()`` to an implementation that lacks support
2538 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002601- Issue #2550: The approach used by client/server code for obtaining
2602 ports to listen on in network-oriented tests has been refined in an
2603 effort to facilitate running multiple instances of the entire
2604 regression test suite in parallel without issue.
2605 test_support.bind_port() has been fixed such that it will always
2606 return a unique port -- which wasn't always the case with the
2607 previous implementation, especially if socket options had been set
2608 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2609 new implementation of bind_port() will actually raise an exception
2610 if it is passed an AF_INET/SOCK_STREAM socket with either the
2611 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2612 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2613 the socket it's been passed. This currently only applies to
2614 Windows. This option prevents any other sockets from binding to the
2615 host/port we've bound to, thus removing the possibility of the
2616 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2617 when a second SOCK_STREAM socket binds and accepts to a host/port
2618 that's already been bound by another socket. The optional preferred
2619 port parameter to bind_port() has been removed. Under no
2620 circumstances should tests be hard coding ports!
2621
2622 test_support.find_unused_port() has also been introduced, which will
2623 pass a temporary socket object to bind_port() in order to obtain an
2624 unused port. The temporary socket object is then closed and
2625 deleted, and the port is returned. This method should only be used
2626 for obtaining an unused port in order to pass to an external program
2627 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2628 a parameter to a server-oriented class that doesn't give you direct
2629 access to the underlying socket used.
2630
2631 Finally, test_support.HOST has been introduced, which should be used
2632 for the host argument of any relevant socket calls (i.e. bind and
2633 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002634
2635 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002636 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002637 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2638 test_asynchat and test_socket_ssl.
2639
Georg Brandl3ee81df2008-05-17 18:14:43 +00002640 It is now possible for multiple instances of the regression test
2641 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002825 optional: it defaults to the traceback of the exception that is
2826 currently being handled (is mandatory to be in the middle of an
2827 exception, otherwise it raises ValueError).

2843 from 't' to '?'.
2844
Thomas Heller78b8f442008-03-05 14:53:39 +00002845- The bundled libffi copy is now in sync with the recently released
2846 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002847 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2848 files are used. On all linux systems the --with-system-ffi
2849 configure option defaults to "yes".

2907Core and builtins
2908-----------------
2909
Fred Drakea8ee94b2008-03-01 02:45:07 +00002910- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002911 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002912
Georg Brandlad61bc82008-02-23 15:11:18 +00002913- Issue #2067: file.__exit__() now calls subclasses' close() method.
2914
2915- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002916
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002917- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002918 issue 215555 for a discussion.
2919
Eric Smitha73fbe72008-02-23 03:09:44 +00002920- Added the future_builtins module, which contains hex() and oct().
2921 These are the PEP 3127 version of these functions, designed to be
2922 compatible with the hex() and oct() builtins from Python 3.0. They
2923 differ slightly in their output formats from the existing, unchanged
2924 Python 2.6 builtins. The expected usage of the future_builtins
2925 module is:
2926 from future_builtins import hex, oct
2927
Eric Smith7ef40bf2008-02-20 23:34:22 +00002928- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2929 exponents for exponents with absolute value < 100. Follows C99
2930 standard. This is a change on Windows, which would use 3 digits.
2931 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2932 so that any alterations it does to the resulting string will be
2933 available in stringlib/formatter.h (for float.__format__).
2934
Eric Smith5a3c1352008-02-19 13:21:56 +00002935- Implemented PEP 3101, Advanced String Formatting. This adds a new
2936 builtin format(); a format() method for str and unicode; a
2937 __format__() method to object, str, unicode, int, long, float, and
2938 datetime; the class string.Formatter; and the C API
2939 PyObject_Format().
2940
Georg Brandl3ee81df2008-05-17 18:14:43 +00002941- Fixed several potential crashes, all caused by specially crafted
2942 __del__ methods exploiting objects in temporarily inconsistent
2943 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002944
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002945- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002946 prevent a possible crash: an Abstract Base Class would try to access
2947 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002948
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- Fixed repr() and str() of complex numbers with infinity or nan as
2950 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002951
Georg Brandl3ee81df2008-05-17 18:14:43 +00002952- Clear all free lists during a gc.collect() of the highest generation
2953 in order to allow pymalloc to free more arenas. Python may give back
2954 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002955
Georg Brandl3ee81df2008-05-17 18:14:43 +00002956- Issue #2045: Fix an infinite recursion triggered when printing a
2957 subclass of collections.defaultdict, if its default_factory is set
2958 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002959
Christian Heimesf75dbef2008-02-08 00:11:31 +00002960- Fixed a minor memory leak in dictobject.c. The content of the free
2961 list was not freed on interpreter shutdown.
2962
Georg Brandl3ee81df2008-05-17 18:14:43 +00002963- Limit free list of method and builtin function objects to 256
2964 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002965
Georg Brandl3ee81df2008-05-17 18:14:43 +00002966- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2967 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002968 to compact the internal free lists of pre-allocted ints and floats.
2969
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2971 calls. Python expected the return type int but the fork familie
2972 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002973
Georg Brandl3ee81df2008-05-17 18:14:43 +00002974- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2975 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002976
Georg Brandl3ee81df2008-05-17 18:14:43 +00002977- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2978 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002979
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2981 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002983- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2984 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002985
Georg Brandl3ee81df2008-05-17 18:14:43 +00002986- Patch #1473257: generator objects gain a gi_code attribute. This is
2987 the same object as the func_code attribute of the function that
2988 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002989
Georg Brandl3ee81df2008-05-17 18:14:43 +00002990- Issue #1920: "while 0" statements were completely removed by the
2991 compiler, even in the presence of an "else" clause, which is
2992 supposed to be run when the condition is false. Now the compiler
2993 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002994
Guido van Rossumeead05f2008-01-24 18:21:02 +00002995- A few crashers fixed: weakref_in_del.py (issue #1377858);
2996 loosing_dict_ref.py (issue #1303614, test67.py);
2997 borrowed_ref_[34].py (not in tracker).
2998
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002999- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003000 suppressed while an extension is loaded by calling SetErrorMode in
3001 dynload_win.c. The error is still reported properly.
3002
Georg Brandl3ee81df2008-05-17 18:14:43 +00003003- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003004 several extension methods and modules do not work without unicode
3005 support.
3006
Georg Brandl26543b12008-01-21 18:36:51 +00003007- Issue #1882: when compiling code from a string, encoding cookies in the
3008 second line of code were not always recognized correctly.
3009
Georg Brandl14404b62008-01-19 19:27:05 +00003010- Issue #1679: "0x" was taken as a valid integer literal.
3011
Georg Brandl6caad7d2008-01-26 14:19:22 +00003012- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003013 added.
3014
Christian Heimesc94e2b52008-01-14 04:13:37 +00003015- sys.float_info / PyFloat_GetInfo: The floating point information
3016 object was converted from a dict to a specialized structseq object.
3017
Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Patch #1816: Added sys.flags structseq. It exposes the status of
3019 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003020
Georg Brandl3ee81df2008-05-17 18:14:43 +00003021- Objects/structseq.c: Implemented new structseq representation. The
3022 patch makes structseqs (e.g. the return value of os.stat) more
3023 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003024
Georg Brandl3ee81df2008-05-17 18:14:43 +00003025- Patch #1700288: added a type attribute cache that caches method

3034 envvar and sys.dont_write_bytecode attribute. All these can be set
3035 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003036
Georg Brandl3ee81df2008-05-17 18:14:43 +00003037- Improve some exception messages when Windows fails to load an
3038 extension module. Now we get for example '%1 is not a valid Win32
3039 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003040

Christian Heimes0a8143f2007-12-18 23:22:54 +00003046- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003047 and INF. float("nan"), float("inf") and float("-inf") now work on
3048 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003049
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050- Compiler now generates simpler and faster code for dictionary
3051 literals. The oparg for BUILD_MAP now indicates an estimated
3052 dictionary size. There is a new opcode, STORE_MAP, for adding
3053 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003082- Patch #1739468: Directories and zipfiles containing a __main__.py
3083 file can now be directly executed by passing their name to the
3084 interpreter. The directory/zipfile is automatically inserted as the
3085 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Issue #1265: Fix a problem with sys.settrace, if the tracing
3088 function uses a generator expression when at the same time the
3089 executed code is closing a paused generator.

3096
Georg Brandl3ee81df2008-05-17 18:14:43 +00003097- The enumerate() builtin function is no longer bounded to sequences
3098 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3099 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003100
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101- Issue #1686386: Tuple's tp_repr did not take into account the
3102 possibility of having a self-referential tuple, which is possible
3103 from C code. Nor did object's tp_str consider that a type's tp_str
3104 could do something that could lead to an inifinite recursion.
3105 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3106 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003107
Georg Brandl3ee81df2008-05-17 18:14:43 +00003108- Issue #1164: It was possible to trigger deadlock when using the
3109 'print' statement to write to a file since the GIL was not released
3110 as needed. Now PyObject_Print() does the right thing along with
3111 various tp_print implementations of the built-in types and those in
3112 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003113
Georg Brandl3ee81df2008-05-17 18:14:43 +00003114- Issue #1147: Exceptions were directly allowing string exceptions in
3115 their throw() method even though string exceptions no longer
3116 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003118- Issue #1096: Prevent a segfault from getting the repr of a very
3119 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003120
Brett Cannon1e534b52007-09-07 04:18:30 +00003121- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122 PyObject_Call() never calling back out to Python code to trigger
3123 recursion depth updates/checks. Required the creation of a static
3124 RuntimeError instance in case normalizing an exception put the
3125 recursion check value past its limit. Fixes crashers
3126 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003141- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003142 __*__ attributes. (Some already existed, e.g., __doc__ and
3143 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003144
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003145- Add -3 option to the interpreter to warn about features that are
3146 deprecated and will be changed/removed in Python 3.0.
3147
Georg Brandl2134e752007-05-21 20:34:16 +00003148- Patch #1686487: you can now pass any mapping after '**' in function
3149 calls.
3150
Collin Winter62903052007-05-18 23:11:24 +00003151- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003152 "except E as target:". This is to provide forwards compatibility
3153 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00003155- Deprecate BaseException.message as per PEP 352.
3156
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157- Issue #1303614: don't expose object's __dict__ when the dict is

3159
Vinay Sajip8549ce32007-05-06 17:53:37 +00003160- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003161 setting a plain string, ie don't expand to single letter identifiers.
3162
Raymond Hettinger13936692007-04-11 18:40:58 +00003163- Request #1191699: Slices can now be pickled.
3164
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003165- Request #1193128: str.translate() now allows a None argument for
3166 translations that only remove characters without re-mapping the
3167 remaining characters.
3168
Georg Brandl5cb76c12007-03-21 09:00:39 +00003169- Patch #1682205: a TypeError while unpacking an iterable is no longer

3171
Neal Norwitzaa754b72007-03-21 06:39:48 +00003172- Remove unused file Python/fmod.c.
3173
Guido van Rossum143b5642007-03-23 04:58:42 +00003174- Bug #1683368: The object.__init__() and object.__new__() methods are
3175 now stricter in rejecting excess arguments. The only time when
3176 either allows excess arguments is when it is not overridden and the
3177 other one is. For backwards compatibility, when both are
3178 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003179 warning later). Also, type.__init__() insists on the same signature
3180 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3183 object to complex using its __complex__() method before falling back
3184 to the __float__() method. Therefore, the functions in the cmath
3185 module now can operate on objects that define a __complex__()
3186 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003187
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188- Patch #1623563: allow __class__ assignment for classes with
3189 __slots__. The old and the new class are still required to have the
3190 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003191

3196 ``object.__reduce_ex__()`` is called with an object that is faking
3197 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003198
Georg Brandl3ee81df2008-05-17 18:14:43 +00003199- Patch #1680015: Don't modify __slots__ tuple if it contains an

3203
Georg Brandl7b9c5552007-03-12 14:30:05 +00003204- Bug #1678647: write a newline after printing an exception in any
3205 case, even when converting the value to a string failed.
3206
Georg Brandl871f1bc2007-03-12 13:17:36 +00003207- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003208 its argument, if it exists. If not, it will work like before. This
3209 allows customizing the output of dir() in the presence of a
3210 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003211
Collin Winter276887b2007-03-12 16:11:39 +00003212- Patch #922167: Python no longer segfaults when faced with infinitely
3213 self-recursive reload() calls (as reported by bug #742342).
3214
Georg Brandl3ee81df2008-05-17 18:14:43 +00003215- Patch #1675981: remove unreachable code from ``type.__new__()``
3216 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003218- Patch #1491866: change the complex() constructor to allow
3219 parthensized forms. This means complex(repr(x)) now works instead of
3220 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003221
Georg Brandlaa2321b2007-03-07 00:40:28 +00003222- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003223 makes the filenames the warning module prints much more sensible
3224 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003225

Georg Brandl098cd692007-03-06 12:17:50 +00003236
Georg Brandl0fca97a2007-03-05 22:28:08 +00003237- Patch #1674228: when assigning a slice (old-style), check for the
3238 sq_ass_slice instead of the sq_slice slot.
3239
Georg Brandl3ee81df2008-05-17 18:14:43 +00003240- When printing an unraisable error, don't print exceptions. before
3241 the name. This duplicates the behavior whening normally printing
3242 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003243
Georg Brandl3ee81df2008-05-17 18:14:43 +00003244- Bug #1653736: Properly discard third argument to

3299
Armin Rigo7ccbca92006-10-04 12:17:45 +00003300- A number of places, including integer negation and absolute value,

3867 TestCase and TestSuite subclasses (not instances) are no longer
3868 accepted in TestSuite.addTest(). This should cause no

3870 -- the failure just occurred later, with a more cumbersome
3871 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4153 with RFC 3207 and forgets any knowledge obtained from the server not
4154 obtained from the TLS negotiation itself. Patch contributed by Bill
4155 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004156
Georg Brandl3ee81df2008-05-17 18:14:43 +00004157- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004158 that the SMTP.starttls() caller no longer needs to call ehlo()
4159 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004160 does not claim to support starttls. Adds the
4161 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4242 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4243 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004245

Georg Brandl3ee81df2008-05-17 18:14:43 +00004260 time so that opening a database previously created with the DB_DUP
4261 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4262 opens. Specifically: dictionary assignment to a DB object will
4263 replace all values for a given key when the database allows
4264 duplicate values. DB users should use DB.put(k, v) when they want
4265 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004266

4272 characters with ASCII value less than 32. Also, it correctly quotes
4273 dots only if they occur on a single line, as opposed to the previous
4274 behavior of quoting dots if they are the second character of any
4275 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004276

4540 without this option!
4541
Martin v. Löwis63bf1492007-11-12 05:14:05 +00004542- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
4543
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004544- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004545 periodic threadstate and signal checking in tight loops. By
4546 default, this option is turned-off. It should only be enabled in
4547 debugged, performance critical applications.

4563 returned by python-config if Python was built with --enable-shared
4564 because that prevented the shared library from being used.

4598-----
4599
Georg Brandl3ee81df2008-05-17 18:14:43 +00004600- Unified naming convention for free lists and their limits. All free
4601 lists in Object/ are named ``free_list``, the counter ``numfree``
4602 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4603 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004604
Georg Brandl3ee81df2008-05-17 18:14:43 +00004605- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4606 to ``PyTuple_SetItem``, it can be used to populate a brand new
4607 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004608
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004609- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

4616
4617- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4618 ``PyFloat_GetInfo()`` to the float API.
4619
Georg Brandl3ee81df2008-05-17 18:14:43 +00004620- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4621 of w# format code incorrectly truncated the length to an int, even
4622 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4623 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004624
Georg Brandl3ee81df2008-05-17 18:14:43 +00004625- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4643- Fix some leftovers from the conversion from int to Py_ssize_t
4644 (relevant to strings and sequences of more than 2**31 items).
4645
4646- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4647 outside of pystate.c and should not be necessary.
4648
Georg Brandl3ee81df2008-05-17 18:14:43 +00004649- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4650 absolute imports. In earlier versions they might have used relative
4651 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004652
Georg Brandl3ee81df2008-05-17 18:14:43 +00004653- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4654 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004655
Georg Brandl3ee81df2008-05-17 18:14:43 +00004656- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4664 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4665 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4666 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004667

Georg Brandl3ee81df2008-05-17 18:14:43 +00004681- Removed the macfs module. It had been deprecated since Python 2.5.
4682 This lead to the deprecation of macostools.touched() as it relied
4683 solely on macfs and was a no-op under OS X.
