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

1318- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1319 302 conformant loader) will now work correctly in most cases (they

1480What's New in Python 2.6.1
1481==========================
1482
1483*Release date: 04-Dec-2008*
1484
1485Core and Builtins
1486-----------------
1487
1488- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1489 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1490 instead of throwing a MemoryError.
1491
1492- Issue #4367: Python would segfault during compiling when the unicodedata
1493 module couldn't be imported and \N escapes were present.
1494
1495- Issue #4348: Some bytearray methods returned that didn't cause any change to
1496 the bytearray, returned the same bytearray instead of a copy.
1497
1498- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1499
1500- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1501
1502- Issue #4048: The parser module now correctly validates relative imports.
1503
1504- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1505 exec statement.
1506
1507- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1508 method does not return iterators for the 4th and 5th items.
1509
1510- Issue #4209: Enabling unicode_literals and the print_function in the same
1511 __future__ import didn't work.
1512
1513- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1514 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1515 really executed because I cannot move to such directory on win2k)
1516
1517- Issue #4069: When set.remove(element) is used with a set element, the element
1518 is temporarily replaced with an equivalent frozenset. But the eventual
1519 KeyError would always report the empty frozenset([]) as the missing key. Now
1520 it correctly refers to the initial element.
1521
1522- Fixed C99 style comments in several files. Python is now C89 compatible
1523 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001670- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1671
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001672- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1673 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1674 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1675 ``printf`` function, whereas PyString_FromFormat has an independent
1676 implementation and uses "%zd" on all platforms for size_t values.
1677 This makes a difference on win64, where ``printf`` needs "%Id" to display
1678 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001680- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1684 object; previously an int would be returned for small values. the __long__
1685 method is allowed to return either an int or a long, but the behaviour of
1686 float objects should not change to respect backward compatibility.
1687
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001688- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001694 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001695 was correctly parsed but parsing of subsequent arguments failed.
1696
Vinay Sajip35e3b032008-09-01 14:33:59 +00001697- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001698 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1699 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1700 when given a tuple of classes as second argument, were looking up
1701 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1702 type object.
1703
Neal Norwitz18aa3882008-08-24 05:04:52 +00001704- Fix crashes on memory allocation failure found with failmalloc.

1844-----------------
1845
Guido van Rossumf8402962008-08-20 15:01:50 +00001846- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1847 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1848 extensions do not automatically benefit from the class attribute
1849 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1850 to their tp_flags field if they care. This is a backwards
1851 compatibility feature; in 3.0, all types will use the cache by
1852 default.
1853
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001854- Keyword arguments can now follow starred arguments. (``f(a, *args,
1855 keyword=23)`` is now valid syntax.)
1856
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001857- ctypes function pointers that are COM methods have a boolean True
1858 value again.

Georg Brandl1e13ea92008-08-11 09:07:59 +00001864- Issue #3537: Fix an assertion failure when an empty but presized dict
1865 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00001867- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1868 ValueError consistently across platforms.
1869
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001870- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1871 (64bit Unix, for example), unichr() would truncate its argument and return
1872 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001876- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1877 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1878
Antoine Pitrou92f82162008-07-25 22:22:08 +00001879- Issue #1819: function calls with several named parameters are now on
1880 average 35% faster (as measured by pybench).
1881
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001882- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1883 the python debugger steps into a class statement: the free variables (local
1884 variables defined in an outer scope) would be deleted from the outer scope.
1885
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001886- Issue #2620: Overflow checking when allocating or reallocating memory
1887 was not always being done properly in some python types and extension
1888 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1889 all been updated to perform better checks and places in the code that
1890 would previously leak memory on the error path when such an allocation
1891 failed have been fixed.

1900
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001901- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1902 version reported by these tools does not necessarily follow the python
1903 version numbering scheme, so the module is less strict when parsing it.
1904
Nick Coghlanf70385a2008-08-18 12:42:46 +00001905- Issue #2235: Added Py3k warnings for types which will become unhashable
1906 under the stricter __hash__ inheritance rules in 3.0. Several types
1907 which did not meet the rules for hash invariants and were already
1908 unhashable in 3.0 have now been explicitly flagged as unhashable in
1909 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1910 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1911
Brett Cannon88f801d2008-08-18 00:46:22 +00001912- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1922 by using 's*' instead of 't#'.
1923
Jesus Cea585ad8a2009-07-02 15:37:21 +00001924- Issue #2222: Fixed reference leak when occurred os.rename()

1934 after a 302 response in the case of not going through a proxy.
1935
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001936- Issue #2676: in the email package, content-type parsing was hanging on
1937 pathological input because of quadratic or exponential behaviour of a
1938 regular expression.
1939
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001940- Issue #3476: binary buffered reading through the new "io" library is now
1941 thread-safe.
1942
Brett Cannonbf3157b2008-08-14 05:00:03 +00001943- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1944 since mimetools itself is deprecated. Because modules are cached, all
1945 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1946
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001947- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001949- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1950 menu entries were not deleted.
1951
Brett Cannon83e81842008-08-09 23:30:55 +00001952- Copied the implementation of reduce() to _functools.reduce() to have a
1953 version that did not raise a DeprecationWarning under -3.
1954
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001955- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1956 a MemoryError rather than silently stop the iteration.
1957
Guido van Rossum59ce9012008-08-09 14:55:34 +00001958- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1959 to _sre.compile() will now be rejected. This should not affect anybody
1960 since the re.compile() function never generates invalid re-bytecode.
1961
Skip Montanaroa032bf42008-08-08 22:52:51 +00001962- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1963 upon first access it can be automatically initialized from the csv file if
1964 it wasn't initialized during instantiation.
1965
Brett Cannon3aa2a492008-08-06 22:28:09 +00001966- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1967 the reload() built-in has been removed.
1968
Brett Cannon7e30b672008-08-04 21:52:25 +00001969- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001970 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1978 raised an AttributeError.
1979
Benjamin Peterson01a24322008-07-28 23:35:27 +00001980- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001981 asking for a specific length. This problem only affected files opened
1982 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001983

2006
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002007- Issue #3394: zipfile.writestr sets external attributes when passed a
2008 file name rather than a ZipInfo instance, so files are extracted with
2009 mode 0600 rather than 000 under Unix.
2010
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002011- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2012 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002023- Issue #2235: the C API function PyObject_HashNotImplemented and its
2024 interaction with the tp_hash slot (added in 2.6b2) are now documented
2025
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002026- Issue #643841: The language reference now provides more detailed
2027 coverage of the lookup process for special methods. The disclaimers
2028 regarding lack of coverage of new-style classes have also been
2029 removed, since the coverage is now fairly reasonable.

2033================================
2034
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002035*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002037Core and Builtins
2038-----------------
2039
Georg Brandl3e483f62008-07-16 22:57:41 +00002040- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2041 its methods now allow for items objects that can be converted to
2042 an integer using operator.index().
2043
Mark Dickinson64b7e502008-07-16 09:40:03 +00002044- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2045 produced a ValueError instead of giving the correct float.
2046
Eric Smitha5fa5a22008-07-16 00:11:49 +00002047- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2048 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2049
Mark Dickinson7103aa42008-07-15 19:08:33 +00002050- Issue #3008: the float type has a new instance method 'float.hex'
2051 and a new class method 'float.fromhex' to convert floating-point
2052 numbers to and from hexadecimal strings, respectively.
2053
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002054- Issue #2235: __hash__ is once again inherited by default. To allow
2055 collections.Hashable to remain meaningful in the presence of the
2056 default hash implementation (object.__hash__), it is now possible
2057 to explicit block inheritance of hash by setting __hash__=None at
2058 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2059 level.
2060
Nick Coghlanb028f502008-07-13 14:52:36 +00002061- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2062 the parent module cannot be found while performing an absolute import.
2063 This means that an incorrectly defined __package__ attribute will
2064 now only prevent relative imports in that module rather than causing
2065 all imports from that module to fail.
2066
Nick Coghlan14ff9942008-07-08 14:21:42 +00002067- Issue #2517: Allow unicode messages in Exceptions again by correctly
2068 bypassing the instance dictionary when looking up __unicode__ on
2069 new-style classes.
2070
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002071- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2072 set to a custom object whose write() method happens to install
2073 another file in sys.stdout.
2074
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002075- Issue #3088: Corrected a race condition in classes derived from
2076 threading.local: the first member set by a thread could be saved in
2077 another thread's dictionary.
2078
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002079- Issue #3004: Minor change to slice.indices(): the start and stop
2080 arguments are now treated identically, making the behaviour easier
2081 to describe and understand. For example, slice(None, -10,
2082 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2083 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2084 10, -1).
2085
Georg Brandl278fc502008-07-19 12:46:12 +00002086- Issue #3219: Calling a function with repeated keyword arguments,
2087 f(a=2, a=23), would not cause a syntax error. This was a regression
2088 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002089
Georg Brandl278fc502008-07-19 12:46:12 +00002090- Issue #2862: Make int and float freelist management consistent with
2091 other freelists. Changes their CompactFreeList apis into
2092 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002097- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2098 api functions without holding the GIL, which could lead to a fatal
2099 error when they failed.
2100
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002101- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2111
Vinay Sajip51e65192008-07-18 09:01:10 +00002112- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2118 incomplete structure was created.
2119

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002126- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2127 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002128 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002129 content-length. The problem had been corrected in the 2.4 branch, but never
2130 merged into trunk.
2131

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002145- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2146 handling is now the same as that of other special attributes like __name__).
2147
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002148- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00002538 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002539
2540 This is controlled by the configure argument ``--with-universal-archs``:
2541
2542 - ``--with-universal-archs=all``: install 4-way universal
2543
2544 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2545
2546 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2547
2548 This option should be used in combination with ``--enable-universalsdk=``.
2549
2550 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 +00002600- Issue #1631171: Re-implement the 'warnings' module in C (the
2601 original Python code has been kept as backup). This will allow for
2602 using the 'warning's machinery in such places as the parser where
2603 use of pure Python code is not possible. Both the ``showarning()``
2604 and ``formatwarning()`` gain an optional 'line' argument which is
2605 not called by default for backwards-compatibility reasons. Setting
2606 ``warnings.showwarning()`` to an implementation that lacks support
2607 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002670- Issue #2550: The approach used by client/server code for obtaining
2671 ports to listen on in network-oriented tests has been refined in an
2672 effort to facilitate running multiple instances of the entire
2673 regression test suite in parallel without issue.
2674 test_support.bind_port() has been fixed such that it will always
2675 return a unique port -- which wasn't always the case with the
2676 previous implementation, especially if socket options had been set
2677 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2678 new implementation of bind_port() will actually raise an exception
2679 if it is passed an AF_INET/SOCK_STREAM socket with either the
2680 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2681 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2682 the socket it's been passed. This currently only applies to
2683 Windows. This option prevents any other sockets from binding to the
2684 host/port we've bound to, thus removing the possibility of the
2685 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2686 when a second SOCK_STREAM socket binds and accepts to a host/port
2687 that's already been bound by another socket. The optional preferred
2688 port parameter to bind_port() has been removed. Under no
2689 circumstances should tests be hard coding ports!
2690
2691 test_support.find_unused_port() has also been introduced, which will
2692 pass a temporary socket object to bind_port() in order to obtain an
2693 unused port. The temporary socket object is then closed and
2694 deleted, and the port is returned. This method should only be used
2695 for obtaining an unused port in order to pass to an external program
2696 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2697 a parameter to a server-oriented class that doesn't give you direct
2698 access to the underlying socket used.
2699
2700 Finally, test_support.HOST has been introduced, which should be used
2701 for the host argument of any relevant socket calls (i.e. bind and
2702 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002703
2704 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002705 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

2707 test_asynchat and test_socket_ssl.
2708
Georg Brandl3ee81df2008-05-17 18:14:43 +00002709 It is now possible for multiple instances of the regression test

2976Core and builtins
2977-----------------
2978
Fred Drakea8ee94b2008-03-01 02:45:07 +00002979- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002980 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002981
Georg Brandlad61bc82008-02-23 15:11:18 +00002982- Issue #2067: file.__exit__() now calls subclasses' close() method.
2983
2984- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002985
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002986- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002987 issue 215555 for a discussion.
2988
Eric Smitha73fbe72008-02-23 03:09:44 +00002989- Added the future_builtins module, which contains hex() and oct().
2990 These are the PEP 3127 version of these functions, designed to be
2991 compatible with the hex() and oct() builtins from Python 3.0. They
2992 differ slightly in their output formats from the existing, unchanged
2993 Python 2.6 builtins. The expected usage of the future_builtins
2994 module is:
2995 from future_builtins import hex, oct
2996
Eric Smith7ef40bf2008-02-20 23:34:22 +00002997- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2998 exponents for exponents with absolute value < 100. Follows C99
2999 standard. This is a change on Windows, which would use 3 digits.
3000 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3001 so that any alterations it does to the resulting string will be
3002 available in stringlib/formatter.h (for float.__format__).
3003
Eric Smith5a3c1352008-02-19 13:21:56 +00003004- Implemented PEP 3101, Advanced String Formatting. This adds a new
3005 builtin format(); a format() method for str and unicode; a
3006 __format__() method to object, str, unicode, int, long, float, and
3007 datetime; the class string.Formatter; and the C API
3008 PyObject_Format().
3009
Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Fixed several potential crashes, all caused by specially crafted
3011 __del__ methods exploiting objects in temporarily inconsistent
3012 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003013
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003014- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003015 prevent a possible crash: an Abstract Base Class would try to access
3016 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003017
Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Fixed repr() and str() of complex numbers with infinity or nan as
3019 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003020
Georg Brandl3ee81df2008-05-17 18:14:43 +00003021- Clear all free lists during a gc.collect() of the highest generation
3022 in order to allow pymalloc to free more arenas. Python may give back
3023 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003024
Georg Brandl3ee81df2008-05-17 18:14:43 +00003025- Issue #2045: Fix an infinite recursion triggered when printing a
3026 subclass of collections.defaultdict, if its default_factory is set
3027 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003028
Christian Heimesf75dbef2008-02-08 00:11:31 +00003029- Fixed a minor memory leak in dictobject.c. The content of the free
3030 list was not freed on interpreter shutdown.
3031
Georg Brandl5a7eca12010-03-21 19:29:04 +00003032- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003033 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003034
Georg Brandl3ee81df2008-05-17 18:14:43 +00003035- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3036 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003037 to compact the internal free lists of pre-allocted ints and floats.
3038
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3040 calls. Python expected the return type int but the fork familie
3041 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003042
Georg Brandl3ee81df2008-05-17 18:14:43 +00003043- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3044 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003045
Georg Brandl3ee81df2008-05-17 18:14:43 +00003046- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3047 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003048
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3050 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003051
Georg Brandl3ee81df2008-05-17 18:14:43 +00003052- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3053 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003054
Georg Brandl3ee81df2008-05-17 18:14:43 +00003055- Patch #1473257: generator objects gain a gi_code attribute. This is
3056 the same object as the func_code attribute of the function that
3057 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003058
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Issue #1920: "while 0" statements were completely removed by the
3060 compiler, even in the presence of an "else" clause, which is
3061 supposed to be run when the condition is false. Now the compiler
3062 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003063
Guido van Rossumeead05f2008-01-24 18:21:02 +00003064- A few crashers fixed: weakref_in_del.py (issue #1377858);
3065 loosing_dict_ref.py (issue #1303614, test67.py);
3066 borrowed_ref_[34].py (not in tracker).
3067
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003068- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003069 suppressed while an extension is loaded by calling SetErrorMode in
3070 dynload_win.c. The error is still reported properly.
3071
Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003073 several extension methods and modules do not work without unicode
3074 support.
3075
Georg Brandl26543b12008-01-21 18:36:51 +00003076- Issue #1882: when compiling code from a string, encoding cookies in the
3077 second line of code were not always recognized correctly.
3078
Georg Brandl14404b62008-01-19 19:27:05 +00003079- Issue #1679: "0x" was taken as a valid integer literal.
3080
Georg Brandl6caad7d2008-01-26 14:19:22 +00003081- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003082 added.
3083
Christian Heimesc94e2b52008-01-14 04:13:37 +00003084- sys.float_info / PyFloat_GetInfo: The floating point information
3085 object was converted from a dict to a specialized structseq object.
3086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Patch #1816: Added sys.flags structseq. It exposes the status of
3088 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003089
Georg Brandl3ee81df2008-05-17 18:14:43 +00003090- Objects/structseq.c: Implemented new structseq representation. The
3091 patch makes structseqs (e.g. the return value of os.stat) more
3092 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003093
Georg Brandl3ee81df2008-05-17 18:14:43 +00003094- Patch #1700288: added a type attribute cache that caches method
3095 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003096
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003097- Bug #1776: __import__() no longer accepts filenames on any platform.
3098 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003099
Georg Brandlaed6c662008-01-07 17:25:53 +00003100- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3101
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3103 envvar and sys.dont_write_bytecode attribute. All these can be set
3104 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003105
Georg Brandl3ee81df2008-05-17 18:14:43 +00003106- Improve some exception messages when Windows fails to load an
3107 extension module. Now we get for example '%1 is not a valid Win32
3108 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003112- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3113 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003114
Christian Heimes0a8143f2007-12-18 23:22:54 +00003115- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116 and INF. float("nan"), float("inf") and float("-inf") now work on
3117 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003118
Georg Brandl3ee81df2008-05-17 18:14:43 +00003119- Compiler now generates simpler and faster code for dictionary
3120 literals. The oparg for BUILD_MAP now indicates an estimated
3121 dictionary size. There is a new opcode, STORE_MAP, for adding
3122 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003123
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Issue #1620: New property decorator syntax was modifying the
3127 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003128
Georg Brandl3ee81df2008-05-17 18:14:43 +00003129- Issue #1538: Avoid copying string in split/rsplit if the split char
3130 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003131
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003132- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003133 SystemError.
3134
Nick Coghlanef01d822007-12-03 12:55:17 +00003135- PEP 366: Allow explicit relative imports when executing modules
3136 inside packages with the -m switch via a new module level
3137 __package__ attribute.
3138
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Issue #1402: Fix a crash on exit, when another thread is still
3140 running, and if the deallocation of its frames somehow calls the
3141 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003142

Georg Brandl3ee81df2008-05-17 18:14:43 +00003151- Patch #1739468: Directories and zipfiles containing a __main__.py
3152 file can now be directly executed by passing their name to the
3153 interpreter. The directory/zipfile is automatically inserted as the
3154 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003155
Georg Brandl3ee81df2008-05-17 18:14:43 +00003156- Issue #1265: Fix a problem with sys.settrace, if the tracing
3157 function uses a generator expression when at the same time the
3158 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003159
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003160- sets and frozensets now have an isdisjoint() method.
3161
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003162- optimize the performance of builtin.sum().
3163
Neal Norwitz44f326e2007-10-05 05:29:17 +00003164- Fix warnings found by the new version of the Coverity checker.
3165
Georg Brandl5a7eca12010-03-21 19:29:04 +00003166- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3168 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003169
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170- Issue #1686386: Tuple's tp_repr did not take into account the
3171 possibility of having a self-referential tuple, which is possible
3172 from C code. Nor did object's tp_str consider that a type's tp_str
3173 could do something that could lead to an inifinite recursion.
3174 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3175 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003176
Georg Brandl3ee81df2008-05-17 18:14:43 +00003177- Issue #1164: It was possible to trigger deadlock when using the
3178 'print' statement to write to a file since the GIL was not released
3179 as needed. Now PyObject_Print() does the right thing along with
3180 various tp_print implementations of the built-in types and those in
3181 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003182
Georg Brandl3ee81df2008-05-17 18:14:43 +00003183- Issue #1147: Exceptions were directly allowing string exceptions in
3184 their throw() method even though string exceptions no longer
3185 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003186

Brett Cannon1e534b52007-09-07 04:18:30 +00003190- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191 PyObject_Call() never calling back out to Python code to trigger
3192 recursion depth updates/checks. Required the creation of a static
3193 RuntimeError instance in case normalizing an exception put the
3194 recursion check value past its limit. Fixes crashers
3195 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003196

Neal Norwitz0ac60192007-05-27 04:08:54 +00003210- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003211 __*__ attributes. (Some already existed, e.g., __doc__ and
3212 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003213
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003214- Add -3 option to the interpreter to warn about features that are
3215 deprecated and will be changed/removed in Python 3.0.
3216
Georg Brandl2134e752007-05-21 20:34:16 +00003217- Patch #1686487: you can now pass any mapping after '**' in function
3218 calls.
3219
Collin Winter62903052007-05-18 23:11:24 +00003220- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003221 "except E as target:". This is to provide forwards compatibility
3222 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003223
Brett Cannon229cee22007-05-05 01:34:02 +00003224- Deprecate BaseException.message as per PEP 352.
3225
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003227 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003228
Vinay Sajip8549ce32007-05-06 17:53:37 +00003229- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003230 setting a plain string, ie don't expand to single letter identifiers.
3231
Raymond Hettinger13936692007-04-11 18:40:58 +00003232- Request #1191699: Slices can now be pickled.
3233
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003234- Request #1193128: str.translate() now allows a None argument for
3235 translations that only remove characters without re-mapping the
3236 remaining characters.
3237
Georg Brandl5cb76c12007-03-21 09:00:39 +00003238- Patch #1682205: a TypeError while unpacking an iterable is no longer
3239 masked by a generic one with the message "unpack non-sequence".
3240

3242
Guido van Rossum143b5642007-03-23 04:58:42 +00003243- Bug #1683368: The object.__init__() and object.__new__() methods are
3244 now stricter in rejecting excess arguments. The only time when
3245 either allows excess arguments is when it is not overridden and the
3246 other one is. For backwards compatibility, when both are
3247 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003248 warning later). Also, type.__init__() insists on the same signature
3249 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003250
Georg Brandl3ee81df2008-05-17 18:14:43 +00003251- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3252 object to complex using its __complex__() method before falling back
3253 to the __float__() method. Therefore, the functions in the cmath
3254 module now can operate on objects that define a __complex__()
3255 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003257- Patch #1623563: allow __class__ assignment for classes with
3258 __slots__. The old and the new class are still required to have the
3259 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003260

3266 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003267

3272
Georg Brandl7b9c5552007-03-12 14:30:05 +00003273- Bug #1678647: write a newline after printing an exception in any
3274 case, even when converting the value to a string failed.
3275
Georg Brandl871f1bc2007-03-12 13:17:36 +00003276- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277 its argument, if it exists. If not, it will work like before. This
3278 allows customizing the output of dir() in the presence of a
3279 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003280
Collin Winter276887b2007-03-12 16:11:39 +00003281- Patch #922167: Python no longer segfaults when faced with infinitely
3282 self-recursive reload() calls (as reported by bug #742342).
3283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Patch #1675981: remove unreachable code from ``type.__new__()``
3285 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003287- Patch #1491866: change the complex() constructor to allow
3288 parthensized forms. This means complex(repr(x)) now works instead of
3289 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003290
Georg Brandlaa2321b2007-03-07 00:40:28 +00003291- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003292 makes the filenames the warning module prints much more sensible
3293 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003294
Georg Brandl49aafc92007-03-07 00:34:46 +00003295- Variant of patch #697613: don't exit the interpreter on a SystemExit
3296 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297 variable is given, but break into the interactive interpreter just

3304 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003305
Georg Brandl0fca97a2007-03-05 22:28:08 +00003306- Patch #1674228: when assigning a slice (old-style), check for the
3307 sq_ass_slice instead of the sq_slice slot.
3308
Georg Brandl3ee81df2008-05-17 18:14:43 +00003309- When printing an unraisable error, don't print exceptions. before
3310 the name. This duplicates the behavior whening normally printing
3311 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003312
Georg Brandl3ee81df2008-05-17 18:14:43 +00003313- Bug #1653736: Properly discard third argument to

3320 created a weakref on itself during a __del__ call for new-style
3321 classes (classic classes still have the bug).

3815 work started with create_connection() and timeout in httplib, and
3816 closes patch #723312.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003844 AttributeError instead of an IOError when the server's response
3845 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003851- Patch #1429539: pdb now correctly initializes the __main__ module
3852 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003853 correctly now.
3854

3877
Georg Brandl92a6bae2007-03-13 17:43:32 +00003878- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003879 are set for invalid interpolation sequences that would lead to
3880 errors on reading back those values.

Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +00003916- Patch #742598: Add .timeout attribute to SocketServer that calls

3934

3936 TestCase and TestSuite subclasses (not instances) are no longer
3937 accepted in TestSuite.addTest(). This should cause no
3938 incompatibility since it never made sense with ordinary subclasses
3939 -- the failure just occurred later, with a more cumbersome
3940 exception.

4219 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004220
Georg Brandl3ee81df2008-05-17 18:14:43 +00004221- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4222 with RFC 3207 and forgets any knowledge obtained from the server not
4223 obtained from the TLS negotiation itself. Patch contributed by Bill
4224 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004225
Georg Brandl3ee81df2008-05-17 18:14:43 +00004226- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004227 that the SMTP.starttls() caller no longer needs to call ehlo()
4228 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004229 does not claim to support starttls. Adds the
4230 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4311 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4312 silently miscode subclasses of those types. Now, it raises a
4313 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004314

Georg Brandl3ee81df2008-05-17 18:14:43 +00004329 time so that opening a database previously created with the DB_DUP
4330 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4331 opens. Specifically: dictionary assignment to a DB object will
4332 replace all values for a given key when the database allows
4333 duplicate values. DB users should use DB.put(k, v) when they want
4334 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004335

4341 characters with ASCII value less than 32. Also, it correctly quotes
4342 dots only if they occur on a single line, as opposed to the previous
4343 behavior of quoting dots if they are the second character of any
4344 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004345

4675 to ``PyTuple_SetItem``, it can be used to populate a brand new
4676 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004680- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4681 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4682 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004683
4684- Patch #1720595: add T_BOOL to the range of structmember types.
4685
4686- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4687 ``PyFloat_GetInfo()`` to the float API.
4688
Georg Brandl3ee81df2008-05-17 18:14:43 +00004689- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4690 of w# format code incorrectly truncated the length to an int, even
4691 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4692 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004693
Georg Brandl3ee81df2008-05-17 18:14:43 +00004694- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4695 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004697- PEP 3123: Provide forward compatibility with Python 3.0, while
4698 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4699 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004701- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4702 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004703
4704- Patch #1733960: Allow T_LONGLONG to accept ints.
4705
4706- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4707
Christian Heimes000a0742008-01-03 22:16:32 +00004708- Added a new API function ``PyImport_ImportModuleNoBlock``.
4709
Georg Brandl6caad7d2008-01-26 14:19:22 +00004710- Bug #1637022: Prefix AST symbols with _Py_.
4711
4712- Fix some leftovers from the conversion from int to Py_ssize_t
4713 (relevant to strings and sequences of more than 2**31 items).
4714
4715- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4716 outside of pystate.c and should not be necessary.
4717
Georg Brandl3ee81df2008-05-17 18:14:43 +00004718- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4719 absolute imports. In earlier versions they might have used relative
4720 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004721
Georg Brandl3ee81df2008-05-17 18:14:43 +00004722- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4723 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004724
Georg Brandl3ee81df2008-05-17 18:14:43 +00004725- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4726 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004732- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4733 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4734 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4735 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004736
Georg Brandl3ee81df2008-05-17 18:14:43 +00004737- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4738 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004750- Removed the macfs module. It had been deprecated since Python 2.5.
4751 This lead to the deprecation of macostools.touched() as it relied
4752 solely on macfs and was a no-op under OS X.
