53- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
54 embedders of the interpreter to set sys.argv without also modifying

1320- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1321 302 conformant loader) will now work correctly in most cases (they

1482What's New in Python 2.6.1
1483==========================
1484
1485*Release date: 04-Dec-2008*
1486
1487Core and Builtins
1488-----------------
1489
1490- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1491 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1492 instead of throwing a MemoryError.
1493
1494- Issue #4367: Python would segfault during compiling when the unicodedata
1495 module couldn't be imported and \N escapes were present.
1496
1497- Issue #4348: Some bytearray methods returned that didn't cause any change to
1498 the bytearray, returned the same bytearray instead of a copy.
1499
1500- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1501
1502- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1503
1504- Issue #4048: The parser module now correctly validates relative imports.
1505
1506- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1507 exec statement.
1508
1509- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1510 method does not return iterators for the 4th and 5th items.
1511
1512- Issue #4209: Enabling unicode_literals and the print_function in the same
1513 __future__ import didn't work.
1514
1515- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1516 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1517 really executed because I cannot move to such directory on win2k)
1518
1519- Issue #4069: When set.remove(element) is used with a set element, the element
1520 is temporarily replaced with an equivalent frozenset. But the eventual
1521 KeyError would always report the empty frozenset([]) as the missing key. Now
1522 it correctly refers to the initial element.
1523
1524- Fixed C99 style comments in several files. Python is now C89 compatible
1525 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001672- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1673
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001674- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1675 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1676 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1677 ``printf`` function, whereas PyString_FromFormat has an independent
1678 implementation and uses "%zd" on all platforms for size_t values.
1679 This makes a difference on win64, where ``printf`` needs "%Id" to display
1680 64bit values.
1681
Benjamin Peterson97179b02008-09-09 20:55:01 +00001682- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1686 object; previously an int would be returned for small values. the __long__
1687 method is allowed to return either an int or a long, but the behaviour of
1688 float objects should not change to respect backward compatibility.
1689
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001690- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001696 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001697 was correctly parsed but parsing of subsequent arguments failed.
1698
Vinay Sajip35e3b032008-09-01 14:33:59 +00001699- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001700 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1701 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1702 when given a tuple of classes as second argument, were looking up
1703 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1704 type object.
1705
Neal Norwitz18aa3882008-08-24 05:04:52 +00001706- Fix crashes on memory allocation failure found with failmalloc.

1846-----------------
1847
Guido van Rossumf8402962008-08-20 15:01:50 +00001848- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1849 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1850 extensions do not automatically benefit from the class attribute
1851 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1852 to their tp_flags field if they care. This is a backwards
1853 compatibility feature; in 3.0, all types will use the cache by
1854 default.
1855
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001856- Keyword arguments can now follow starred arguments. (``f(a, *args,

1858
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001859- ctypes function pointers that are COM methods have a boolean True
1860 value again.

Georg Brandl1e13ea92008-08-11 09:07:59 +00001866- Issue #3537: Fix an assertion failure when an empty but presized dict
1867 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00001869- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1870 ValueError consistently across platforms.
1871
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001872- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1873 (64bit Unix, for example), unichr() would truncate its argument and return
1874 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001878- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1879 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1880
Antoine Pitrou92f82162008-07-25 22:22:08 +00001881- Issue #1819: function calls with several named parameters are now on
1882 average 35% faster (as measured by pybench).
1883
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001884- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1885 the python debugger steps into a class statement: the free variables (local
1886 variables defined in an outer scope) would be deleted from the outer scope.
1887
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001888- Issue #2620: Overflow checking when allocating or reallocating memory
1889 was not always being done properly in some python types and extension
1890 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1891 all been updated to perform better checks and places in the code that
1892 would previously leak memory on the error path when such an allocation
1893 failed have been fixed.

1902
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001903- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1904 version reported by these tools does not necessarily follow the python
1905 version numbering scheme, so the module is less strict when parsing it.
1906
Nick Coghlanf70385a2008-08-18 12:42:46 +00001907- Issue #2235: Added Py3k warnings for types which will become unhashable
1908 under the stricter __hash__ inheritance rules in 3.0. Several types
1909 which did not meet the rules for hash invariants and were already
1910 unhashable in 3.0 have now been explicitly flagged as unhashable in
1911 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1912 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1913
Brett Cannon88f801d2008-08-18 00:46:22 +00001914- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1915 imported into the module but exposed as part of the module's API.
1916

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001923- Issue #3575: Incremental decoder's decode function now takes bytearray
1924 by using 's*' instead of 't#'.
1925
Jesus Cea585ad8a2009-07-02 15:37:21 +00001926- Issue #2222: Fixed reference leak when occurred os.rename()

Facundo Batistaeb90b782008-08-16 14:44:07 +00001935- Issue #2776: fixed small issue when handling an URL with double slash
1936 after a 302 response in the case of not going through a proxy.
1937
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001938- Issue #2676: in the email package, content-type parsing was hanging on
1939 pathological input because of quadratic or exponential behaviour of a
1940 regular expression.
1941
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001942- Issue #3476: binary buffered reading through the new "io" library is now
1943 thread-safe.
1944
Brett Cannonbf3157b2008-08-14 05:00:03 +00001945- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1946 since mimetools itself is deprecated. Because modules are cached, all
1947 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1948
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001949- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001951- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1952 menu entries were not deleted.
1953
Brett Cannon83e81842008-08-09 23:30:55 +00001954- Copied the implementation of reduce() to _functools.reduce() to have a
1955 version that did not raise a DeprecationWarning under -3.
1956
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001957- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1958 a MemoryError rather than silently stop the iteration.
1959
Guido van Rossum59ce9012008-08-09 14:55:34 +00001960- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1961 to _sre.compile() will now be rejected. This should not affect anybody
1962 since the re.compile() function never generates invalid re-bytecode.
1963
Skip Montanaroa032bf42008-08-08 22:52:51 +00001964- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1965 upon first access it can be automatically initialized from the csv file if
1966 it wasn't initialized during instantiation.
1967
Brett Cannon3aa2a492008-08-06 22:28:09 +00001968- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1969 the reload() built-in has been removed.
1970
Brett Cannon7e30b672008-08-04 21:52:25 +00001971- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001972 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1980 raised an AttributeError.
1981
Benjamin Peterson01a24322008-07-28 23:35:27 +00001982- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001983 asking for a specific length. This problem only affected files opened
1984 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001985

2008
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002009- Issue #3394: zipfile.writestr sets external attributes when passed a
2010 file name rather than a ZipInfo instance, so files are extracted with
2011 mode 0600 rather than 000 under Unix.
2012
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002013- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2014 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002025- Issue #2235: the C API function PyObject_HashNotImplemented and its
2026 interaction with the tp_hash slot (added in 2.6b2) are now documented
2027
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002028- Issue #643841: The language reference now provides more detailed
2029 coverage of the lookup process for special methods. The disclaimers
2030 regarding lack of coverage of new-style classes have also been
2031 removed, since the coverage is now fairly reasonable.

2035================================
2036
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002037*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002039Core and Builtins
2040-----------------
2041
Georg Brandl3e483f62008-07-16 22:57:41 +00002042- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2043 its methods now allow for items objects that can be converted to
2044 an integer using operator.index().
2045
Mark Dickinson64b7e502008-07-16 09:40:03 +00002046- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2047 produced a ValueError instead of giving the correct float.
2048
Eric Smitha5fa5a22008-07-16 00:11:49 +00002049- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2050 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2051
Mark Dickinson7103aa42008-07-15 19:08:33 +00002052- Issue #3008: the float type has a new instance method 'float.hex'
2053 and a new class method 'float.fromhex' to convert floating-point
2054 numbers to and from hexadecimal strings, respectively.
2055
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002056- Issue #2235: __hash__ is once again inherited by default. To allow
2057 collections.Hashable to remain meaningful in the presence of the
2058 default hash implementation (object.__hash__), it is now possible
2059 to explicit block inheritance of hash by setting __hash__=None at
2060 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2061 level.
2062
Nick Coghlanb028f502008-07-13 14:52:36 +00002063- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2064 the parent module cannot be found while performing an absolute import.
2065 This means that an incorrectly defined __package__ attribute will
2066 now only prevent relative imports in that module rather than causing
2067 all imports from that module to fail.
2068
Nick Coghlan14ff9942008-07-08 14:21:42 +00002069- Issue #2517: Allow unicode messages in Exceptions again by correctly
2070 bypassing the instance dictionary when looking up __unicode__ on
2071 new-style classes.
2072
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002073- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2074 set to a custom object whose write() method happens to install
2075 another file in sys.stdout.
2076
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002077- Issue #3088: Corrected a race condition in classes derived from
2078 threading.local: the first member set by a thread could be saved in
2079 another thread's dictionary.
2080
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002081- Issue #3004: Minor change to slice.indices(): the start and stop
2082 arguments are now treated identically, making the behaviour easier
2083 to describe and understand. For example, slice(None, -10,
2084 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2085 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2086 10, -1).
2087
Georg Brandl278fc502008-07-19 12:46:12 +00002088- Issue #3219: Calling a function with repeated keyword arguments,
2089 f(a=2, a=23), would not cause a syntax error. This was a regression
2090 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002091
Georg Brandl278fc502008-07-19 12:46:12 +00002092- Issue #2862: Make int and float freelist management consistent with
2093 other freelists. Changes their CompactFreeList apis into
2094 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002099- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2100 api functions without holding the GIL, which could lead to a fatal
2101 error when they failed.
2102
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002103- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2112 ForkingPickler.register() to resolve conflict with ctypes.
2113
Vinay Sajip51e65192008-07-18 09:01:10 +00002114- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2117 a valid dlerror() message.
2118
Thomas Heller2bad6572008-07-15 17:19:50 +00002119- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2120 incomplete structure was created.
2121

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002126- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002127
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002128- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2129 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002130 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002131 content-length. The problem had been corrected in the 2.4 branch, but never
2132 merged into trunk.
2133
Georg Brandle78fbcc2008-07-05 10:13:36 +00002134- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002147- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2148 handling is now the same as that of other special attributes like __name__).
2149
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002150- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00002540 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002541
2542 This is controlled by the configure argument ``--with-universal-archs``:
2543
2544 - ``--with-universal-archs=all``: install 4-way universal
2545
2546 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2547
2548 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2549
2550 This option should be used in combination with ``--enable-universalsdk=``.
2551
2552 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 +00002602- Issue #1631171: Re-implement the 'warnings' module in C (the
2603 original Python code has been kept as backup). This will allow for
2604 using the 'warning's machinery in such places as the parser where
2605 use of pure Python code is not possible. Both the ``showarning()``
2606 and ``formatwarning()`` gain an optional 'line' argument which is
2607 not called by default for backwards-compatibility reasons. Setting
2608 ``warnings.showwarning()`` to an implementation that lacks support
2609 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002672- Issue #2550: The approach used by client/server code for obtaining
2673 ports to listen on in network-oriented tests has been refined in an
2674 effort to facilitate running multiple instances of the entire
2675 regression test suite in parallel without issue.
2676 test_support.bind_port() has been fixed such that it will always
2677 return a unique port -- which wasn't always the case with the
2678 previous implementation, especially if socket options had been set
2679 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2680 new implementation of bind_port() will actually raise an exception
2681 if it is passed an AF_INET/SOCK_STREAM socket with either the
2682 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2683 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2684 the socket it's been passed. This currently only applies to
2685 Windows. This option prevents any other sockets from binding to the
2686 host/port we've bound to, thus removing the possibility of the
2687 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2688 when a second SOCK_STREAM socket binds and accepts to a host/port
2689 that's already been bound by another socket. The optional preferred
2690 port parameter to bind_port() has been removed. Under no
2691 circumstances should tests be hard coding ports!
2692
2693 test_support.find_unused_port() has also been introduced, which will
2694 pass a temporary socket object to bind_port() in order to obtain an
2695 unused port. The temporary socket object is then closed and
2696 deleted, and the port is returned. This method should only be used
2697 for obtaining an unused port in order to pass to an external program
2698 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2699 a parameter to a server-oriented class that doesn't give you direct
2700 access to the underlying socket used.
2701
2702 Finally, test_support.HOST has been introduced, which should be used
2703 for the host argument of any relevant socket calls (i.e. bind and
2704 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002705
2706 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002707 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

2709 test_asynchat and test_socket_ssl.
2710
Georg Brandl3ee81df2008-05-17 18:14:43 +00002711 It is now possible for multiple instances of the regression test

2978Core and builtins
2979-----------------
2980
Fred Drakea8ee94b2008-03-01 02:45:07 +00002981- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002982 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002983
Georg Brandlad61bc82008-02-23 15:11:18 +00002984- Issue #2067: file.__exit__() now calls subclasses' close() method.
2985
2986- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002987
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002988- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002989 issue 215555 for a discussion.
2990
Eric Smitha73fbe72008-02-23 03:09:44 +00002991- Added the future_builtins module, which contains hex() and oct().
2992 These are the PEP 3127 version of these functions, designed to be
2993 compatible with the hex() and oct() builtins from Python 3.0. They
2994 differ slightly in their output formats from the existing, unchanged
2995 Python 2.6 builtins. The expected usage of the future_builtins
2996 module is:
2997 from future_builtins import hex, oct
2998
Eric Smith7ef40bf2008-02-20 23:34:22 +00002999- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3000 exponents for exponents with absolute value < 100. Follows C99
3001 standard. This is a change on Windows, which would use 3 digits.
3002 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3003 so that any alterations it does to the resulting string will be
3004 available in stringlib/formatter.h (for float.__format__).
3005
Eric Smith5a3c1352008-02-19 13:21:56 +00003006- Implemented PEP 3101, Advanced String Formatting. This adds a new
3007 builtin format(); a format() method for str and unicode; a
3008 __format__() method to object, str, unicode, int, long, float, and
3009 datetime; the class string.Formatter; and the C API
3010 PyObject_Format().
3011
Georg Brandl3ee81df2008-05-17 18:14:43 +00003012- Fixed several potential crashes, all caused by specially crafted
3013 __del__ methods exploiting objects in temporarily inconsistent
3014 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003015
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003016- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017 prevent a possible crash: an Abstract Base Class would try to access
3018 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003019
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Fixed repr() and str() of complex numbers with infinity or nan as
3021 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003022
Georg Brandl3ee81df2008-05-17 18:14:43 +00003023- Clear all free lists during a gc.collect() of the highest generation
3024 in order to allow pymalloc to free more arenas. Python may give back
3025 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003026
Georg Brandl3ee81df2008-05-17 18:14:43 +00003027- Issue #2045: Fix an infinite recursion triggered when printing a
3028 subclass of collections.defaultdict, if its default_factory is set
3029 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003030
Christian Heimesf75dbef2008-02-08 00:11:31 +00003031- Fixed a minor memory leak in dictobject.c. The content of the free
3032 list was not freed on interpreter shutdown.
3033
Georg Brandl5a7eca12010-03-21 19:29:04 +00003034- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003035 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003036
Georg Brandl3ee81df2008-05-17 18:14:43 +00003037- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3038 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003039 to compact the internal free lists of pre-allocted ints and floats.
3040
Georg Brandl3ee81df2008-05-17 18:14:43 +00003041- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3042 calls. Python expected the return type int but the fork familie
3043 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003044
Georg Brandl3ee81df2008-05-17 18:14:43 +00003045- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3046 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003047
Georg Brandl3ee81df2008-05-17 18:14:43 +00003048- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3049 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003050
Georg Brandl3ee81df2008-05-17 18:14:43 +00003051- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3052 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003053
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3055 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Patch #1473257: generator objects gain a gi_code attribute. This is
3058 the same object as the func_code attribute of the function that
3059 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003060
Georg Brandl3ee81df2008-05-17 18:14:43 +00003061- Issue #1920: "while 0" statements were completely removed by the
3062 compiler, even in the presence of an "else" clause, which is
3063 supposed to be run when the condition is false. Now the compiler
3064 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003065
Guido van Rossumeead05f2008-01-24 18:21:02 +00003066- A few crashers fixed: weakref_in_del.py (issue #1377858);
3067 loosing_dict_ref.py (issue #1303614, test67.py);
3068 borrowed_ref_[34].py (not in tracker).
3069
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003070- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003071 suppressed while an extension is loaded by calling SetErrorMode in
3072 dynload_win.c. The error is still reported properly.
3073
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003075 several extension methods and modules do not work without unicode
3076 support.
3077
Georg Brandl26543b12008-01-21 18:36:51 +00003078- Issue #1882: when compiling code from a string, encoding cookies in the
3079 second line of code were not always recognized correctly.
3080
Georg Brandl14404b62008-01-19 19:27:05 +00003081- Issue #1679: "0x" was taken as a valid integer literal.
3082
Georg Brandl6caad7d2008-01-26 14:19:22 +00003083- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003084 added.
3085
Christian Heimesc94e2b52008-01-14 04:13:37 +00003086- sys.float_info / PyFloat_GetInfo: The floating point information
3087 object was converted from a dict to a specialized structseq object.
3088
Georg Brandl3ee81df2008-05-17 18:14:43 +00003089- Patch #1816: Added sys.flags structseq. It exposes the status of
3090 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003091
Georg Brandl3ee81df2008-05-17 18:14:43 +00003092- Objects/structseq.c: Implemented new structseq representation. The
3093 patch makes structseqs (e.g. the return value of os.stat) more
3094 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003095
Georg Brandl3ee81df2008-05-17 18:14:43 +00003096- Patch #1700288: added a type attribute cache that caches method
3097 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003098
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003099- Bug #1776: __import__() no longer accepts filenames on any platform.
3100 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003101
Georg Brandlaed6c662008-01-07 17:25:53 +00003102- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3103
Georg Brandl3ee81df2008-05-17 18:14:43 +00003104- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3105 envvar and sys.dont_write_bytecode attribute. All these can be set
3106 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003107
Georg Brandl3ee81df2008-05-17 18:14:43 +00003108- Improve some exception messages when Windows fails to load an
3109 extension module. Now we get for example '%1 is not a valid Win32
3110 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003111
Georg Brandl3ee81df2008-05-17 18:14:43 +00003112- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003114- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3115 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003116
Christian Heimes0a8143f2007-12-18 23:22:54 +00003117- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003118 and INF. float("nan"), float("inf") and float("-inf") now work on
3119 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003120
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121- Compiler now generates simpler and faster code for dictionary
3122 literals. The oparg for BUILD_MAP now indicates an estimated
3123 dictionary size. There is a new opcode, STORE_MAP, for adding
3124 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003125
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003131- Issue #1538: Avoid copying string in split/rsplit if the split char
3132 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003133
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003134- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003135 SystemError.
3136
Nick Coghlanef01d822007-12-03 12:55:17 +00003137- PEP 366: Allow explicit relative imports when executing modules

3139 __package__ attribute.
3140
Georg Brandl3ee81df2008-05-17 18:14:43 +00003141- Issue #1402: Fix a crash on exit, when another thread is still
3142 running, and if the deallocation of its frames somehow calls the
3143 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003144

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003148 attribute of an empty cell object.
3149
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Issue #1460: The utf-7 incremental decoder did not accept truncated
3151 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003152
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153- Patch #1739468: Directories and zipfiles containing a __main__.py
3154 file can now be directly executed by passing their name to the
3155 interpreter. The directory/zipfile is automatically inserted as the
3156 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003157
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158- Issue #1265: Fix a problem with sys.settrace, if the tracing
3159 function uses a generator expression when at the same time the
3160 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003161
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003162- sets and frozensets now have an isdisjoint() method.
3163
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003164- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00003166- Fix warnings found by the new version of the Coverity checker.
3167
Georg Brandl5a7eca12010-03-21 19:29:04 +00003168- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003169 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3170 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003171
Georg Brandl3ee81df2008-05-17 18:14:43 +00003172- Issue #1686386: Tuple's tp_repr did not take into account the
3173 possibility of having a self-referential tuple, which is possible
3174 from C code. Nor did object's tp_str consider that a type's tp_str
3175 could do something that could lead to an inifinite recursion.
3176 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3177 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003178
Georg Brandl3ee81df2008-05-17 18:14:43 +00003179- Issue #1164: It was possible to trigger deadlock when using the
3180 'print' statement to write to a file since the GIL was not released
3181 as needed. Now PyObject_Print() does the right thing along with
3182 various tp_print implementations of the built-in types and those in
3183 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Issue #1147: Exceptions were directly allowing string exceptions in
3186 their throw() method even though string exceptions no longer
3187 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003188

Brett Cannon1e534b52007-09-07 04:18:30 +00003192- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003193 PyObject_Call() never calling back out to Python code to trigger
3194 recursion depth updates/checks. Required the creation of a static
3195 RuntimeError instance in case normalizing an exception put the
3196 recursion check value past its limit. Fixes crashers
3197 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003198

Neal Norwitz0ac60192007-05-27 04:08:54 +00003212- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003213 __*__ attributes. (Some already existed, e.g., __doc__ and
3214 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003215
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003216- Add -3 option to the interpreter to warn about features that are
3217 deprecated and will be changed/removed in Python 3.0.
3218
Georg Brandl2134e752007-05-21 20:34:16 +00003219- Patch #1686487: you can now pass any mapping after '**' in function
3220 calls.
3221
Collin Winter62903052007-05-18 23:11:24 +00003222- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003223 "except E as target:". This is to provide forwards compatibility
3224 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003225
Brett Cannon229cee22007-05-05 01:34:02 +00003226- Deprecate BaseException.message as per PEP 352.
3227
Georg Brandl3ee81df2008-05-17 18:14:43 +00003228- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003229 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003230
Vinay Sajip8549ce32007-05-06 17:53:37 +00003231- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003232 setting a plain string, ie don't expand to single letter identifiers.
3233
Raymond Hettinger13936692007-04-11 18:40:58 +00003234- Request #1191699: Slices can now be pickled.
3235
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003236- Request #1193128: str.translate() now allows a None argument for
3237 translations that only remove characters without re-mapping the
3238 remaining characters.
3239
Georg Brandl5cb76c12007-03-21 09:00:39 +00003240- Patch #1682205: a TypeError while unpacking an iterable is no longer
3241 masked by a generic one with the message "unpack non-sequence".
3242
Neal Norwitzaa754b72007-03-21 06:39:48 +00003243- Remove unused file Python/fmod.c.
3244
Guido van Rossum143b5642007-03-23 04:58:42 +00003245- Bug #1683368: The object.__init__() and object.__new__() methods are
3246 now stricter in rejecting excess arguments. The only time when
3247 either allows excess arguments is when it is not overridden and the
3248 other one is. For backwards compatibility, when both are
3249 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003250 warning later). Also, type.__init__() insists on the same signature
3251 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003252
Georg Brandl3ee81df2008-05-17 18:14:43 +00003253- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3254 object to complex using its __complex__() method before falling back
3255 to the __float__() method. Therefore, the functions in the cmath
3256 module now can operate on objects that define a __complex__()
3257 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003258
Georg Brandl3ee81df2008-05-17 18:14:43 +00003259- Patch #1623563: allow __class__ assignment for classes with
3260 __slots__. The old and the new class are still required to have the
3261 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003262

3268 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003269

3274
Georg Brandl7b9c5552007-03-12 14:30:05 +00003275- Bug #1678647: write a newline after printing an exception in any
3276 case, even when converting the value to a string failed.
3277
Georg Brandl871f1bc2007-03-12 13:17:36 +00003278- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003279 its argument, if it exists. If not, it will work like before. This
3280 allows customizing the output of dir() in the presence of a
3281 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003282
Collin Winter276887b2007-03-12 16:11:39 +00003283- Patch #922167: Python no longer segfaults when faced with infinitely
3284 self-recursive reload() calls (as reported by bug #742342).
3285
Georg Brandl3ee81df2008-05-17 18:14:43 +00003286- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003289- Patch #1491866: change the complex() constructor to allow
3290 parthensized forms. This means complex(repr(x)) now works instead of
3291 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003292
Georg Brandlaa2321b2007-03-07 00:40:28 +00003293- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003294 makes the filenames the warning module prints much more sensible
3295 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003296
Georg Brandl49aafc92007-03-07 00:34:46 +00003297- Variant of patch #697613: don't exit the interpreter on a SystemExit
3298 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299 variable is given, but break into the interactive interpreter just

3306 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003307
Georg Brandl0fca97a2007-03-05 22:28:08 +00003308- Patch #1674228: when assigning a slice (old-style), check for the
3309 sq_ass_slice instead of the sq_slice slot.
3310
Georg Brandl3ee81df2008-05-17 18:14:43 +00003311- When printing an unraisable error, don't print exceptions. before
3312 the name. This duplicates the behavior whening normally printing
3313 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003314
Georg Brandl3ee81df2008-05-17 18:14:43 +00003315- Bug #1653736: Properly discard third argument to

3322 created a weakref on itself during a __del__ call for new-style
3323 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003846 AttributeError instead of an IOError when the server's response
3847 didn't contain a valid HTTP status line.

3938 TestCase and TestSuite subclasses (not instances) are no longer
3939 accepted in TestSuite.addTest(). This should cause no
3940 incompatibility since it never made sense with ordinary subclasses
3941 -- the failure just occurred later, with a more cumbersome
3942 exception.

Walter Dörwald84a3efe2007-06-13 16:57:12 +00004222
Georg Brandl3ee81df2008-05-17 18:14:43 +00004223- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4224 with RFC 3207 and forgets any knowledge obtained from the server not
4225 obtained from the TLS negotiation itself. Patch contributed by Bill
4226 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004227
Georg Brandl3ee81df2008-05-17 18:14:43 +00004228- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004229 that the SMTP.starttls() caller no longer needs to call ehlo()
4230 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004231 does not claim to support starttls. Adds the
4232 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4313 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4314 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004331 time so that opening a database previously created with the DB_DUP
4332 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4333 opens. Specifically: dictionary assignment to a DB object will
4334 replace all values for a given key when the database allows
4335 duplicate values. DB users should use DB.put(k, v) when they want
4336 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004337

4343 characters with ASCII value less than 32. Also, it correctly quotes
4344 dots only if they occur on a single line, as opposed to the previous
4345 behavior of quoting dots if they are the second character of any
4346 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004347

4677 to ``PyTuple_SetItem``, it can be used to populate a brand new
4678 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004682- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4683 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4684 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004685
4686- Patch #1720595: add T_BOOL to the range of structmember types.
4687
4688- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4689 ``PyFloat_GetInfo()`` to the float API.
4690
Georg Brandl3ee81df2008-05-17 18:14:43 +00004691- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4692 of w# format code incorrectly truncated the length to an int, even
4693 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4694 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004695
Georg Brandl3ee81df2008-05-17 18:14:43 +00004696- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4697 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004699- PEP 3123: Provide forward compatibility with Python 3.0, while
4700 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4701 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004702
Georg Brandl3ee81df2008-05-17 18:14:43 +00004703- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4704 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004705
4706- Patch #1733960: Allow T_LONGLONG to accept ints.
4707
4708- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4709
Christian Heimes000a0742008-01-03 22:16:32 +00004710- Added a new API function ``PyImport_ImportModuleNoBlock``.
4711
Georg Brandl6caad7d2008-01-26 14:19:22 +00004712- Bug #1637022: Prefix AST symbols with _Py_.
4713
4714- Fix some leftovers from the conversion from int to Py_ssize_t
4715 (relevant to strings and sequences of more than 2**31 items).
4716
4717- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4718 outside of pystate.c and should not be necessary.
4719
Georg Brandl3ee81df2008-05-17 18:14:43 +00004720- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4721 absolute imports. In earlier versions they might have used relative
4722 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004723
Georg Brandl3ee81df2008-05-17 18:14:43 +00004724- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4725 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004726
Georg Brandl3ee81df2008-05-17 18:14:43 +00004727- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4728 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004734- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4735 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4736 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4737 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004738
Georg Brandl3ee81df2008-05-17 18:14:43 +00004739- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4740 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004752- Removed the macfs module. It had been deprecated since Python 2.5.
4753 This lead to the deprecation of macostools.touched() as it relied
4754 solely on macfs and was a no-op under OS X.
