25 processing: any non-float non-integer argument is now converted to

27 small arguments were treated this way; larger arguments (those whose
28 __int__ was outside the range of a C long) would produce a TypeError.

53- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
54 embedders of the interpreter to set sys.argv without also modifying
55 sys.path. This helps fix `CVE-2008-5983
56 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

1232 which inherited from numbers.py which did not have __slots__ defined. The

1240 check it is possible to segfault the interpreter.

1279 do an explicit seek to the end of file (so that e.g. tell() returns the
1280 file size rather than 0). This is consistent with the behaviour of the
1281 traditional 2.x file object.

1312 zipimport (or any other conformant PEP 302 loader). Original patch by
1313 Alexander Belopolsky.
1314
1315- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1316 302 conformant loader) will now work correctly in most cases (they
1317 are still subject to the constraints that exist for all code running
1318 from inside a module loaded via a PEP 302 loader and attempting to

1477What's New in Python 2.6.1
1478==========================
1479
1480*Release date: 04-Dec-2008*
1481
1482Core and Builtins
1483-----------------
1484
1485- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1486 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1487 instead of throwing a MemoryError.
1488
1489- Issue #4367: Python would segfault during compiling when the unicodedata
1490 module couldn't be imported and \N escapes were present.
1491
1492- Issue #4348: Some bytearray methods returned that didn't cause any change to
1493 the bytearray, returned the same bytearray instead of a copy.
1494
1495- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1496
1497- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1498
1499- Issue #4048: The parser module now correctly validates relative imports.
1500
1501- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1502 exec statement.

1505 method does not return iterators for the 4th and 5th items.
1506
1507- Issue #4209: Enabling unicode_literals and the print_function in the same
1508 __future__ import didn't work.
1509
1510- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1511 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1512 really executed because I cannot move to such directory on win2k)
1513
1514- Issue #4069: When set.remove(element) is used with a set element, the element
1515 is temporarily replaced with an equivalent frozenset. But the eventual
1516 KeyError would always report the empty frozenset([]) as the missing key. Now
1517 it correctly refers to the initial element.
1518
1519- Fixed C99 style comments in several files. Python is now C89 compatible
1520 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001667- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1668
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001669- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1670 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1671 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1672 ``printf`` function, whereas PyString_FromFormat has an independent
1673 implementation and uses "%zd" on all platforms for size_t values.
1674 This makes a difference on win64, where ``printf`` needs "%Id" to display
1675 64bit values.
1676
Benjamin Peterson97179b02008-09-09 20:55:01 +00001677- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1681 object; previously an int would be returned for small values. the __long__
1682 method is allowed to return either an int or a long, but the behaviour of
1683 float objects should not change to respect backward compatibility.
1684
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001685- Issue #3751: str.rpartition would perform a left-partition when called with
1686 a unicode argument.
1687
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001688- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001691 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001692 was correctly parsed but parsing of subsequent arguments failed.
1693
Vinay Sajip35e3b032008-09-01 14:33:59 +00001694- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001695 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1696 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1697 when given a tuple of classes as second argument, were looking up
1698 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1699 type object.
1700
Neal Norwitz18aa3882008-08-24 05:04:52 +00001701- Fix crashes on memory allocation failure found with failmalloc.

1770 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1771 for catch_warnings() also led to an improvement in the raising of a

1841-----------------
1842
Guido van Rossumf8402962008-08-20 15:01:50 +00001843- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1844 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1845 extensions do not automatically benefit from the class attribute
1846 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1847 to their tp_flags field if they care. This is a backwards
1848 compatibility feature; in 3.0, all types will use the cache by
1849 default.
1850
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001851- Keyword arguments can now follow starred arguments. (``f(a, *args,

1853
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001854- ctypes function pointers that are COM methods have a boolean True
1855 value again.

1859 and introducing s*.
1860
Georg Brandl1e13ea92008-08-11 09:07:59 +00001861- Issue #3537: Fix an assertion failure when an empty but presized dict
1862 object was stored in the freelist.
1863
Mark Dickinsonb6467572008-08-04 21:30:09 +00001864- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1865 ValueError consistently across platforms.
1866
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001867- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1868 (64bit Unix, for example), unichr() would truncate its argument and return
1869 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Antoine Pitrou92f82162008-07-25 22:22:08 +00001876- Issue #1819: function calls with several named parameters are now on
1877 average 35% faster (as measured by pybench).
1878
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001879- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1880 the python debugger steps into a class statement: the free variables (local
1881 variables defined in an outer scope) would be deleted from the outer scope.
1882
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001883- Issue #2620: Overflow checking when allocating or reallocating memory
1884 was not always being done properly in some python types and extension
1885 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1886 all been updated to perform better checks and places in the code that
1887 would previously leak memory on the error path when such an allocation
1888 failed have been fixed.

1894
Benjamin Petersone977ad42008-08-20 01:42:01 +00001895- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1896 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1897
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001898- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1899 version reported by these tools does not necessarily follow the python
1900 version numbering scheme, so the module is less strict when parsing it.
1901
Nick Coghlanf70385a2008-08-18 12:42:46 +00001902- Issue #2235: Added Py3k warnings for types which will become unhashable
1903 under the stricter __hash__ inheritance rules in 3.0. Several types
1904 which did not meet the rules for hash invariants and were already
1905 unhashable in 3.0 have now been explicitly flagged as unhashable in
1906 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1907 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1908
Brett Cannon88f801d2008-08-18 00:46:22 +00001909- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001918- Issue #3575: Incremental decoder's decode function now takes bytearray
1919 by using 's*' instead of 't#'.
1920
Jesus Cea585ad8a2009-07-02 15:37:21 +00001921- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001922 fails unicode conversion on 2nd parameter. (windows only)
1923
Facundo Batista94f243a2008-08-17 03:38:39 +00001924- Issue 2464. urllib2 now supports a malformation in the URL received
1925 in a redirect.

1931 after a 302 response in the case of not going through a proxy.
1932
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001933- Issue #2676: in the email package, content-type parsing was hanging on
1934 pathological input because of quadratic or exponential behaviour of a
1935 regular expression.
1936
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001937- Issue #3476: binary buffered reading through the new "io" library is now
1938 thread-safe.
1939
Brett Cannonbf3157b2008-08-14 05:00:03 +00001940- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1941 since mimetools itself is deprecated. Because modules are cached, all
1942 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1943
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001944- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001946- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1947 menu entries were not deleted.
1948
Brett Cannon83e81842008-08-09 23:30:55 +00001949- Copied the implementation of reduce() to _functools.reduce() to have a
1950 version that did not raise a DeprecationWarning under -3.
1951
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001952- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1953 a MemoryError rather than silently stop the iteration.
1954
Guido van Rossum59ce9012008-08-09 14:55:34 +00001955- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1956 to _sre.compile() will now be rejected. This should not affect anybody
1957 since the re.compile() function never generates invalid re-bytecode.
1958
Skip Montanaroa032bf42008-08-08 22:52:51 +00001959- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1960 upon first access it can be automatically initialized from the csv file if
1961 it wasn't initialized during instantiation.
1962
Brett Cannon3aa2a492008-08-06 22:28:09 +00001963- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1964 the reload() built-in has been removed.
1965
Brett Cannon7e30b672008-08-04 21:52:25 +00001966- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001967 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1975 raised an AttributeError.
1976
Benjamin Peterson01a24322008-07-28 23:35:27 +00001977- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001978 asking for a specific length. This problem only affected files opened
1979 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001980

2003
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002004- Issue #3394: zipfile.writestr sets external attributes when passed a
2005 file name rather than a ZipInfo instance, so files are extracted with
2006 mode 0600 rather than 000 under Unix.
2007
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002008- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2009 argument in python 2.5, this broke code that subclassed Popen to include its

2019
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002020- Issue #2235: the C API function PyObject_HashNotImplemented and its
2021 interaction with the tp_hash slot (added in 2.6b2) are now documented
2022
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002023- Issue #643841: The language reference now provides more detailed
2024 coverage of the lookup process for special methods. The disclaimers
2025 regarding lack of coverage of new-style classes have also been
2026 removed, since the coverage is now fairly reasonable.

2030================================
2031
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002032*Release date: 17-Jul-2008*
2033
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002034Core and Builtins
2035-----------------
2036
Georg Brandl3e483f62008-07-16 22:57:41 +00002037- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2038 its methods now allow for items objects that can be converted to
2039 an integer using operator.index().
2040
Mark Dickinson64b7e502008-07-16 09:40:03 +00002041- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2042 produced a ValueError instead of giving the correct float.
2043
Eric Smitha5fa5a22008-07-16 00:11:49 +00002044- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2045 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2046
Mark Dickinson7103aa42008-07-15 19:08:33 +00002047- Issue #3008: the float type has a new instance method 'float.hex'
2048 and a new class method 'float.fromhex' to convert floating-point
2049 numbers to and from hexadecimal strings, respectively.
2050
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002051- Issue #2235: __hash__ is once again inherited by default. To allow
2052 collections.Hashable to remain meaningful in the presence of the
2053 default hash implementation (object.__hash__), it is now possible
2054 to explicit block inheritance of hash by setting __hash__=None at
2055 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2056 level.
2057
Nick Coghlanb028f502008-07-13 14:52:36 +00002058- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2059 the parent module cannot be found while performing an absolute import.
2060 This means that an incorrectly defined __package__ attribute will
2061 now only prevent relative imports in that module rather than causing
2062 all imports from that module to fail.
2063
Nick Coghlan14ff9942008-07-08 14:21:42 +00002064- Issue #2517: Allow unicode messages in Exceptions again by correctly
2065 bypassing the instance dictionary when looking up __unicode__ on
2066 new-style classes.
2067
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002068- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2069 set to a custom object whose write() method happens to install
2070 another file in sys.stdout.
2071
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002072- Issue #3088: Corrected a race condition in classes derived from
2073 threading.local: the first member set by a thread could be saved in
2074 another thread's dictionary.
2075
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002076- Issue #3004: Minor change to slice.indices(): the start and stop
2077 arguments are now treated identically, making the behaviour easier
2078 to describe and understand. For example, slice(None, -10,
2079 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2080 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2081 10, -1).
2082
Georg Brandl278fc502008-07-19 12:46:12 +00002083- Issue #3219: Calling a function with repeated keyword arguments,
2084 f(a=2, a=23), would not cause a syntax error. This was a regression
2085 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002086
Georg Brandl278fc502008-07-19 12:46:12 +00002087- Issue #2862: Make int and float freelist management consistent with
2088 other freelists. Changes their CompactFreeList apis into
2089 ClearFreeList apis and calls them via gc.collect().

2092-------
2093
Thomas Heller57adf222008-08-14 19:10:48 +00002094- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2095 api functions without holding the GIL, which could lead to a fatal
2096 error when they failed.
2097
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002098- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2107 ForkingPickler.register() to resolve conflict with ctypes.
2108
Vinay Sajip51e65192008-07-18 09:01:10 +00002109- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2112 a valid dlerror() message.
2113
Thomas Heller2bad6572008-07-15 17:19:50 +00002114- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2115 incomplete structure was created.
2116

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002121- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002122
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002123- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2124 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002125 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002126 content-length. The problem had been corrected in the 2.4 branch, but never
2127 merged into trunk.
2128
Georg Brandle78fbcc2008-07-05 10:13:36 +00002129- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002140 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002141
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002142- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2143 handling is now the same as that of other special attributes like __name__).
2144
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002145- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2146 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002535 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002536
2537 This is controlled by the configure argument ``--with-universal-archs``:
2538
2539 - ``--with-universal-archs=all``: install 4-way universal
2540
2541 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2542
2543 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2544
2545 This option should be used in combination with ``--enable-universalsdk=``.
2546
2547 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002597- Issue #1631171: Re-implement the 'warnings' module in C (the
2598 original Python code has been kept as backup). This will allow for
2599 using the 'warning's machinery in such places as the parser where
2600 use of pure Python code is not possible. Both the ``showarning()``
2601 and ``formatwarning()`` gain an optional 'line' argument which is
2602 not called by default for backwards-compatibility reasons. Setting
2603 ``warnings.showwarning()`` to an implementation that lacks support
2604 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002667- Issue #2550: The approach used by client/server code for obtaining
2668 ports to listen on in network-oriented tests has been refined in an
2669 effort to facilitate running multiple instances of the entire
2670 regression test suite in parallel without issue.
2671 test_support.bind_port() has been fixed such that it will always
2672 return a unique port -- which wasn't always the case with the
2673 previous implementation, especially if socket options had been set
2674 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2675 new implementation of bind_port() will actually raise an exception
2676 if it is passed an AF_INET/SOCK_STREAM socket with either the
2677 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2678 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2679 the socket it's been passed. This currently only applies to
2680 Windows. This option prevents any other sockets from binding to the
2681 host/port we've bound to, thus removing the possibility of the
2682 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2683 when a second SOCK_STREAM socket binds and accepts to a host/port
2684 that's already been bound by another socket. The optional preferred
2685 port parameter to bind_port() has been removed. Under no
2686 circumstances should tests be hard coding ports!
2687
2688 test_support.find_unused_port() has also been introduced, which will
2689 pass a temporary socket object to bind_port() in order to obtain an
2690 unused port. The temporary socket object is then closed and
2691 deleted, and the port is returned. This method should only be used
2692 for obtaining an unused port in order to pass to an external program
2693 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2694 a parameter to a server-oriented class that doesn't give you direct
2695 access to the underlying socket used.
2696
2697 Finally, test_support.HOST has been introduced, which should be used
2698 for the host argument of any relevant socket calls (i.e. bind and
2699 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002700
2701 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002702 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

2975
Fred Drakea8ee94b2008-03-01 02:45:07 +00002976- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002977 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002978
Georg Brandlad61bc82008-02-23 15:11:18 +00002979- Issue #2067: file.__exit__() now calls subclasses' close() method.
2980
2981- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002982
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002983- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002984 issue 215555 for a discussion.
2985
Eric Smitha73fbe72008-02-23 03:09:44 +00002986- Added the future_builtins module, which contains hex() and oct().
2987 These are the PEP 3127 version of these functions, designed to be
2988 compatible with the hex() and oct() builtins from Python 3.0. They
2989 differ slightly in their output formats from the existing, unchanged
2990 Python 2.6 builtins. The expected usage of the future_builtins
2991 module is:
2992 from future_builtins import hex, oct
2993
Eric Smith7ef40bf2008-02-20 23:34:22 +00002994- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2995 exponents for exponents with absolute value < 100. Follows C99
2996 standard. This is a change on Windows, which would use 3 digits.
2997 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2998 so that any alterations it does to the resulting string will be
2999 available in stringlib/formatter.h (for float.__format__).
3000
Eric Smith5a3c1352008-02-19 13:21:56 +00003001- Implemented PEP 3101, Advanced String Formatting. This adds a new
3002 builtin format(); a format() method for str and unicode; a
3003 __format__() method to object, str, unicode, int, long, float, and
3004 datetime; the class string.Formatter; and the C API
3005 PyObject_Format().
3006
Georg Brandl3ee81df2008-05-17 18:14:43 +00003007- Fixed several potential crashes, all caused by specially crafted
3008 __del__ methods exploiting objects in temporarily inconsistent
3009 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003010
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003011- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003012 prevent a possible crash: an Abstract Base Class would try to access
3013 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003014
Georg Brandl3ee81df2008-05-17 18:14:43 +00003015- Fixed repr() and str() of complex numbers with infinity or nan as
3016 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003017
Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Clear all free lists during a gc.collect() of the highest generation
3019 in order to allow pymalloc to free more arenas. Python may give back
3020 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003021
Georg Brandl3ee81df2008-05-17 18:14:43 +00003022- Issue #2045: Fix an infinite recursion triggered when printing a
3023 subclass of collections.defaultdict, if its default_factory is set
3024 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003025
Christian Heimesf75dbef2008-02-08 00:11:31 +00003026- Fixed a minor memory leak in dictobject.c. The content of the free
3027 list was not freed on interpreter shutdown.
3028
Georg Brandl5a7eca12010-03-21 19:29:04 +00003029- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003031
Georg Brandl3ee81df2008-05-17 18:14:43 +00003032- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3033 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003034 to compact the internal free lists of pre-allocted ints and floats.
3035
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3037 calls. Python expected the return type int but the fork familie
3038 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003039
Georg Brandl3ee81df2008-05-17 18:14:43 +00003040- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3041 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003042
Georg Brandl3ee81df2008-05-17 18:14:43 +00003043- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3044 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003045
Georg Brandl3ee81df2008-05-17 18:14:43 +00003046- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3047 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003048
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3050 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003051
Georg Brandl3ee81df2008-05-17 18:14:43 +00003052- Patch #1473257: generator objects gain a gi_code attribute. This is
3053 the same object as the func_code attribute of the function that
3054 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003055
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056- Issue #1920: "while 0" statements were completely removed by the
3057 compiler, even in the presence of an "else" clause, which is
3058 supposed to be run when the condition is false. Now the compiler
3059 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003060
Guido van Rossumeead05f2008-01-24 18:21:02 +00003061- A few crashers fixed: weakref_in_del.py (issue #1377858);
3062 loosing_dict_ref.py (issue #1303614, test67.py);
3063 borrowed_ref_[34].py (not in tracker).
3064
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003065- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003066 suppressed while an extension is loaded by calling SetErrorMode in
3067 dynload_win.c. The error is still reported properly.
3068
Georg Brandl3ee81df2008-05-17 18:14:43 +00003069- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003070 several extension methods and modules do not work without unicode
3071 support.
3072
Georg Brandl26543b12008-01-21 18:36:51 +00003073- Issue #1882: when compiling code from a string, encoding cookies in the
3074 second line of code were not always recognized correctly.
3075
Georg Brandl14404b62008-01-19 19:27:05 +00003076- Issue #1679: "0x" was taken as a valid integer literal.
3077
Georg Brandl6caad7d2008-01-26 14:19:22 +00003078- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003079 added.
3080
Christian Heimesc94e2b52008-01-14 04:13:37 +00003081- sys.float_info / PyFloat_GetInfo: The floating point information
3082 object was converted from a dict to a specialized structseq object.
3083
Georg Brandl3ee81df2008-05-17 18:14:43 +00003084- Patch #1816: Added sys.flags structseq. It exposes the status of
3085 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Objects/structseq.c: Implemented new structseq representation. The
3088 patch makes structseqs (e.g. the return value of os.stat) more
3089 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003090
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091- Patch #1700288: added a type attribute cache that caches method
3092 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003093
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003094- Bug #1776: __import__() no longer accepts filenames on any platform.
3095 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003096
Georg Brandlaed6c662008-01-07 17:25:53 +00003097- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3098
Georg Brandl3ee81df2008-05-17 18:14:43 +00003099- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3100 envvar and sys.dont_write_bytecode attribute. All these can be set
3101 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Improve some exception messages when Windows fails to load an
3104 extension module. Now we get for example '%1 is not a valid Win32
3105 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003109- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3110 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003111
Christian Heimes0a8143f2007-12-18 23:22:54 +00003112- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003113 and INF. float("nan"), float("inf") and float("-inf") now work on
3114 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003115
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116- Compiler now generates simpler and faster code for dictionary
3117 literals. The oparg for BUILD_MAP now indicates an estimated
3118 dictionary size. There is a new opcode, STORE_MAP, for adding
3119 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003120
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Issue #1538: Avoid copying string in split/rsplit if the split char
3127 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003128
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003129- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003130 SystemError.
3131
Nick Coghlanef01d822007-12-03 12:55:17 +00003132- PEP 366: Allow explicit relative imports when executing modules

3134 __package__ attribute.
3135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Issue #1402: Fix a crash on exit, when another thread is still
3137 running, and if the deallocation of its frames somehow calls the
3138 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003139

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003143 attribute of an empty cell object.
3144
Georg Brandl3ee81df2008-05-17 18:14:43 +00003145- Issue #1460: The utf-7 incremental decoder did not accept truncated
3146 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003147
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- Patch #1739468: Directories and zipfiles containing a __main__.py
3149 file can now be directly executed by passing their name to the
3150 interpreter. The directory/zipfile is automatically inserted as the
3151 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003152
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153- Issue #1265: Fix a problem with sys.settrace, if the tracing
3154 function uses a generator expression when at the same time the
3155 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003156
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003157- sets and frozensets now have an isdisjoint() method.
3158
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003159- optimize the performance of builtin.sum().
3160
Neal Norwitz44f326e2007-10-05 05:29:17 +00003161- Fix warnings found by the new version of the Coverity checker.
3162
Georg Brandl5a7eca12010-03-21 19:29:04 +00003163- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3165 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003166
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Issue #1686386: Tuple's tp_repr did not take into account the
3168 possibility of having a self-referential tuple, which is possible
3169 from C code. Nor did object's tp_str consider that a type's tp_str
3170 could do something that could lead to an inifinite recursion.
3171 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3172 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003173
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174- Issue #1164: It was possible to trigger deadlock when using the
3175 'print' statement to write to a file since the GIL was not released
3176 as needed. Now PyObject_Print() does the right thing along with
3177 various tp_print implementations of the built-in types and those in
3178 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003179
Georg Brandl3ee81df2008-05-17 18:14:43 +00003180- Issue #1147: Exceptions were directly allowing string exceptions in
3181 their throw() method even though string exceptions no longer
3182 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003183
Georg Brandl3ee81df2008-05-17 18:14:43 +00003184- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003187- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188 PyObject_Call() never calling back out to Python code to trigger
3189 recursion depth updates/checks. Required the creation of a static
3190 RuntimeError instance in case normalizing an exception put the
3191 recursion check value past its limit. Fixes crashers
3192 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003193
Georg Brandl3ee81df2008-05-17 18:14:43 +00003194- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003207- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003208 __*__ attributes. (Some already existed, e.g., __doc__ and
3209 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003210
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003211- Add -3 option to the interpreter to warn about features that are
3212 deprecated and will be changed/removed in Python 3.0.
3213
Georg Brandl2134e752007-05-21 20:34:16 +00003214- Patch #1686487: you can now pass any mapping after '**' in function
3215 calls.
3216
Collin Winter62903052007-05-18 23:11:24 +00003217- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003218 "except E as target:". This is to provide forwards compatibility
3219 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003220
Brett Cannon229cee22007-05-05 01:34:02 +00003221- Deprecate BaseException.message as per PEP 352.
3222
Georg Brandl3ee81df2008-05-17 18:14:43 +00003223- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003224 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003225
Vinay Sajip8549ce32007-05-06 17:53:37 +00003226- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003227 setting a plain string, ie don't expand to single letter identifiers.
3228
Raymond Hettinger13936692007-04-11 18:40:58 +00003229- Request #1191699: Slices can now be pickled.

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003231- Request #1193128: str.translate() now allows a None argument for
3232 translations that only remove characters without re-mapping the
3233 remaining characters.
3234
Georg Brandl5cb76c12007-03-21 09:00:39 +00003235- Patch #1682205: a TypeError while unpacking an iterable is no longer

3239
Guido van Rossum143b5642007-03-23 04:58:42 +00003240- Bug #1683368: The object.__init__() and object.__new__() methods are
3241 now stricter in rejecting excess arguments. The only time when
3242 either allows excess arguments is when it is not overridden and the
3243 other one is. For backwards compatibility, when both are
3244 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003245 warning later). Also, type.__init__() insists on the same signature
3246 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003247
Georg Brandl3ee81df2008-05-17 18:14:43 +00003248- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3249 object to complex using its __complex__() method before falling back
3250 to the __float__() method. Therefore, the functions in the cmath
3251 module now can operate on objects that define a __complex__()
3252 method.

3256 same slot names.

3269
Georg Brandl7b9c5552007-03-12 14:30:05 +00003270- Bug #1678647: write a newline after printing an exception in any
3271 case, even when converting the value to a string failed.
3272
Georg Brandl871f1bc2007-03-12 13:17:36 +00003273- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003274 its argument, if it exists. If not, it will work like before. This
3275 allows customizing the output of dir() in the presence of a
3276 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003278- Patch #922167: Python no longer segfaults when faced with infinitely
3279 self-recursive reload() calls (as reported by bug #742342).

3285 parthensized forms. This means complex(repr(x)) now works instead of
3286 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003287
Georg Brandlaa2321b2007-03-07 00:40:28 +00003288- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003289 makes the filenames the warning module prints much more sensible
3290 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003291

3301 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003302
Georg Brandl0fca97a2007-03-05 22:28:08 +00003303- Patch #1674228: when assigning a slice (old-style), check for the
3304 sq_ass_slice instead of the sq_slice slot.
3305
Georg Brandl3ee81df2008-05-17 18:14:43 +00003306- When printing an unraisable error, don't print exceptions. before
3307 the name. This duplicates the behavior whening normally printing
3308 exceptions.

3317 created a weakref on itself during a __del__ call for new-style
3318 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00003358- Bug #1545497: when given an explicit base, int() did ignore NULs
3359 embedded in the string to convert.
3360
Georg Brandl846f73a2006-10-08 07:11:54 +00003361- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003409 generator expressions (x for x, in ... ) works again. Fixing this
3410 problem required changing the .pyc magic number. This means that
3411 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003841 AttributeError instead of an IOError when the server's response

3933 TestCase and TestSuite subclasses (not instances) are no longer

4216 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004217
Georg Brandl3ee81df2008-05-17 18:14:43 +00004218- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4219 with RFC 3207 and forgets any knowledge obtained from the server not
4220 obtained from the TLS negotiation itself. Patch contributed by Bill
4221 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004222
Georg Brandl3ee81df2008-05-17 18:14:43 +00004223- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004224 that the SMTP.starttls() caller no longer needs to call ehlo()
4225 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004226 does not claim to support starttls. Adds the
4227 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4297 contents before adding elements from the iterable. This fix brings
4298 the behavior into line with that for list.__init__().

4308 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4309 silently miscode subclasses of those types. Now, it raises a
4310 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004311

Georg Brandl3ee81df2008-05-17 18:14:43 +00004326 time so that opening a database previously created with the DB_DUP
4327 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4328 opens. Specifically: dictionary assignment to a DB object will
4329 replace all values for a given key when the database allows
4330 duplicate values. DB users should use DB.put(k, v) when they want
4331 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004332

4338 characters with ASCII value less than 32. Also, it correctly quotes
4339 dots only if they occur on a single line, as opposed to the previous
4340 behavior of quoting dots if they are the second character of any
4341 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004342

Georg Brandl6caad7d2008-01-26 14:19:22 +00004680
4681- Patch #1720595: add T_BOOL to the range of structmember types.
4682
4683- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4684 ``PyFloat_GetInfo()`` to the float API.
4685
Georg Brandl3ee81df2008-05-17 18:14:43 +00004686- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4687 of w# format code incorrectly truncated the length to an int, even
4688 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4689 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004690
Georg Brandl3ee81df2008-05-17 18:14:43 +00004691- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4692 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004694- PEP 3123: Provide forward compatibility with Python 3.0, while
4695 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4696 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004698- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4699 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004700
4701- Patch #1733960: Allow T_LONGLONG to accept ints.
4702
4703- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4704
Christian Heimes000a0742008-01-03 22:16:32 +00004705- Added a new API function ``PyImport_ImportModuleNoBlock``.

Georg Brandl6caad7d2008-01-26 14:19:22 +00004707- Bug #1637022: Prefix AST symbols with _Py_.
4708
4709- Fix some leftovers from the conversion from int to Py_ssize_t
4710 (relevant to strings and sequences of more than 2**31 items).
4711
4712- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4713 outside of pystate.c and should not be necessary.
4714
Georg Brandl3ee81df2008-05-17 18:14:43 +00004715- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4716 absolute imports. In earlier versions they might have used relative
4717 imports under some conditions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004719- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4720 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004721
Georg Brandl3ee81df2008-05-17 18:14:43 +00004722- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4723 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004729- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4730 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4731 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4732 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004733
Georg Brandl3ee81df2008-05-17 18:14:43 +00004734- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004747- Removed the macfs module. It had been deprecated since Python 2.5.
4748 This lead to the deprecation of macostools.touched() as it relied
4749 solely on macfs and was a no-op under OS X.
