25 processing: any non-float non-integer argument is now converted to
26 an integer (if possible) using its __int__ method. Previously, only
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.

52
53- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
54 embedders of the interpreter to set sys.argv without also modifying
55 sys.path. This helps fix `CVE-2008-5983
56 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

109

120 Decimal operation raises multiple signals and more than one of those
121 signals is trapped, the specification determines the order in which
122 the signals should be handled. In many cases this order wasn't
123 being followed, leading to the wrong Python exception being raised.
124
Antoine Pitrou01a255a2010-05-03 16:48:13 +0000125- Issue #7865: The close() method of :mod:`io` objects should not swallow

1302
1303- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1304 302 conformant loader) will now work correctly in most cases (they
1305 are still subject to the constraints that exist for all code running
1306 from inside a module loaded via a PEP 302 loader and attempting to

1465What's New in Python 2.6.1
1466==========================
1467
1468*Release date: 04-Dec-2008*
1469
1470Core and Builtins
1471-----------------
1472
1473- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1474 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1475 instead of throwing a MemoryError.
1476
1477- Issue #4367: Python would segfault during compiling when the unicodedata
1478 module couldn't be imported and \N escapes were present.
1479
1480- Issue #4348: Some bytearray methods returned that didn't cause any change to
1481 the bytearray, returned the same bytearray instead of a copy.
1482
1483- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1484
1485- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1486
1487- Issue #4048: The parser module now correctly validates relative imports.
1488
1489- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1490 exec statement.
1491
1492- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1493 method does not return iterators for the 4th and 5th items.
1494
1495- Issue #4209: Enabling unicode_literals and the print_function in the same
1496 __future__ import didn't work.
1497
1498- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1499 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1500 really executed because I cannot move to such directory on win2k)
1501
1502- Issue #4069: When set.remove(element) is used with a set element, the element
1503 is temporarily replaced with an equivalent frozenset. But the eventual
1504 KeyError would always report the empty frozenset([]) as the missing key. Now
1505 it correctly refers to the initial element.
1506
1507- Fixed C99 style comments in several files. Python is now C89 compatible
1508 again.

1590 true singleton object.
1591
Brett Cannonb2d61bd2008-09-29 03:41:21 +00001592- Issue #3895: It was possible to crash the interpreter when an external timer

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001655- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1656
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001657- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1658 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1659 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1660 ``printf`` function, whereas PyString_FromFormat has an independent
1661 implementation and uses "%zd" on all platforms for size_t values.
1662 This makes a difference on win64, where ``printf`` needs "%Id" to display
1663 64bit values.
1664
Benjamin Peterson97179b02008-09-09 20:55:01 +00001665- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1669 object; previously an int would be returned for small values. the __long__
1670 method is allowed to return either an int or a long, but the behaviour of
1671 float objects should not change to respect backward compatibility.
1672
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001673- Issue #3751: str.rpartition would perform a left-partition when called with
1674 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001679 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001680 was correctly parsed but parsing of subsequent arguments failed.
1681
Vinay Sajip35e3b032008-09-01 14:33:59 +00001682- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001683 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1684 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1685 when given a tuple of classes as second argument, were looking up
1686 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1687 type object.
1688
Neal Norwitz18aa3882008-08-24 05:04:52 +00001689- Fix crashes on memory allocation failure found with failmalloc.

1758 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1759 for catch_warnings() also led to an improvement in the raising of a

1829-----------------
1830
Guido van Rossumf8402962008-08-20 15:01:50 +00001831- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1832 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1833 extensions do not automatically benefit from the class attribute
1834 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1835 to their tp_flags field if they care. This is a backwards
1836 compatibility feature; in 3.0, all types will use the cache by
1837 default.
1838
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001839- Keyword arguments can now follow starred arguments. (``f(a, *args,
1840 keyword=23)`` is now valid syntax.)
1841
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001842- ctypes function pointers that are COM methods have a boolean True
1843 value again.
1844
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001845- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1846 by denying s# to parse objects that have a releasebuffer procedure,
1847 and introducing s*.
1848
Georg Brandl1e13ea92008-08-11 09:07:59 +00001849- Issue #3537: Fix an assertion failure when an empty but presized dict
1850 object was stored in the freelist.
1851
Mark Dickinsonb6467572008-08-04 21:30:09 +00001852- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1853 ValueError consistently across platforms.
1854
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001855- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1856 (64bit Unix, for example), unichr() would truncate its argument and return
1857 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1858
Neal Norwitze7d8be82008-07-31 17:17:14 +00001859- Apply security patches from Apple.
1860
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001861- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1862 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1863
Antoine Pitrou92f82162008-07-25 22:22:08 +00001864- Issue #1819: function calls with several named parameters are now on
1865 average 35% faster (as measured by pybench).
1866
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001867- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1868 the python debugger steps into a class statement: the free variables (local
1869 variables defined in an outer scope) would be deleted from the outer scope.
1870
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001871- Issue #2620: Overflow checking when allocating or reallocating memory
1872 was not always being done properly in some python types and extension
1873 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1874 all been updated to perform better checks and places in the code that
1875 would previously leak memory on the error path when such an allocation
1876 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001881- Issue #3612: Added some missing basic types in ctypes.wintypes.
1882
Benjamin Petersone977ad42008-08-20 01:42:01 +00001883- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1884 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1885
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001886- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1887 version reported by these tools does not necessarily follow the python
1888 version numbering scheme, so the module is less strict when parsing it.
1889
Nick Coghlanf70385a2008-08-18 12:42:46 +00001890- Issue #2235: Added Py3k warnings for types which will become unhashable
1891 under the stricter __hash__ inheritance rules in 3.0. Several types
1892 which did not meet the rules for hash invariants and were already
1893 unhashable in 3.0 have now been explicitly flagged as unhashable in
1894 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1895 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1896
Brett Cannon88f801d2008-08-18 00:46:22 +00001897- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1898 imported into the module but exposed as part of the module's API.
1899

1905
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001906- Issue #3575: Incremental decoder's decode function now takes bytearray
1907 by using 's*' instead of 't#'.
1908
Jesus Cea585ad8a2009-07-02 15:37:21 +00001909- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001910 fails unicode conversion on 2nd parameter. (windows only)
1911
Facundo Batista94f243a2008-08-17 03:38:39 +00001912- Issue 2464. urllib2 now supports a malformation in the URL received
1913 in a redirect.
1914
Brett Cannonabe423e2008-08-16 21:47:07 +00001915- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001916 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001917
Facundo Batistaeb90b782008-08-16 14:44:07 +00001918- Issue #2776: fixed small issue when handling an URL with double slash
1919 after a 302 response in the case of not going through a proxy.
1920
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001921- Issue #2676: in the email package, content-type parsing was hanging on
1922 pathological input because of quadratic or exponential behaviour of a
1923 regular expression.
1924
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001925- Issue #3476: binary buffered reading through the new "io" library is now
1926 thread-safe.
1927
Brett Cannonbf3157b2008-08-14 05:00:03 +00001928- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1929 since mimetools itself is deprecated. Because modules are cached, all
1930 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1931
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001932- Issue #3134: shutil referenced undefined WindowsError symbol.
1933
Robert Schuppenies14646332008-08-10 11:01:53 +00001934- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1935 menu entries were not deleted.
1936
Brett Cannon83e81842008-08-09 23:30:55 +00001937- Copied the implementation of reduce() to _functools.reduce() to have a
1938 version that did not raise a DeprecationWarning under -3.
1939
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001940- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1941 a MemoryError rather than silently stop the iteration.
1942
Guido van Rossum59ce9012008-08-09 14:55:34 +00001943- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1944 to _sre.compile() will now be rejected. This should not affect anybody
1945 since the re.compile() function never generates invalid re-bytecode.
1946
Skip Montanaroa032bf42008-08-08 22:52:51 +00001947- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1948 upon first access it can be automatically initialized from the csv file if
1949 it wasn't initialized during instantiation.
1950
Brett Cannon3aa2a492008-08-06 22:28:09 +00001951- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1952 the reload() built-in has been removed.
1953
Brett Cannon7e30b672008-08-04 21:52:25 +00001954- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001955 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1963 raised an AttributeError.
1964
Benjamin Peterson01a24322008-07-28 23:35:27 +00001965- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001966 asking for a specific length. This problem only affected files opened
1967 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001968
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001969- Issue #3449: Update decimal module to use most recent specification
1970 (v. 1.68) and tests (v. 2.58) from IBM.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001992- Issue #3394: zipfile.writestr sets external attributes when passed a
1993 file name rather than a ZipInfo instance, so files are extracted with
1994 mode 0600 rather than 000 under Unix.
1995
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001996- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1997 argument in python 2.5, this broke code that subclassed Popen to include its

2009 interaction with the tp_hash slot (added in 2.6b2) are now documented
2010
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002011- Issue #643841: The language reference now provides more detailed
2012 coverage of the lookup process for special methods. The disclaimers
2013 regarding lack of coverage of new-style classes have also been
2014 removed, since the coverage is now fairly reasonable.

2018================================
2019
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002020*Release date: 17-Jul-2008*
2021
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002022Core and Builtins
2023-----------------
2024
Georg Brandl3e483f62008-07-16 22:57:41 +00002025- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2026 its methods now allow for items objects that can be converted to
2027 an integer using operator.index().
2028
Mark Dickinson64b7e502008-07-16 09:40:03 +00002029- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2030 produced a ValueError instead of giving the correct float.
2031
Eric Smitha5fa5a22008-07-16 00:11:49 +00002032- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2033 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2034
Mark Dickinson7103aa42008-07-15 19:08:33 +00002035- Issue #3008: the float type has a new instance method 'float.hex'
2036 and a new class method 'float.fromhex' to convert floating-point
2037 numbers to and from hexadecimal strings, respectively.
2038
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002039- Issue #2235: __hash__ is once again inherited by default. To allow
2040 collections.Hashable to remain meaningful in the presence of the
2041 default hash implementation (object.__hash__), it is now possible
2042 to explicit block inheritance of hash by setting __hash__=None at
2043 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2044 level.
2045
Nick Coghlanb028f502008-07-13 14:52:36 +00002046- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2047 the parent module cannot be found while performing an absolute import.
2048 This means that an incorrectly defined __package__ attribute will
2049 now only prevent relative imports in that module rather than causing
2050 all imports from that module to fail.
2051
Nick Coghlan14ff9942008-07-08 14:21:42 +00002052- Issue #2517: Allow unicode messages in Exceptions again by correctly
2053 bypassing the instance dictionary when looking up __unicode__ on
2054 new-style classes.
2055
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002056- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2057 set to a custom object whose write() method happens to install
2058 another file in sys.stdout.
2059
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002060- Issue #3088: Corrected a race condition in classes derived from
2061 threading.local: the first member set by a thread could be saved in
2062 another thread's dictionary.
2063
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002064- Issue #3004: Minor change to slice.indices(): the start and stop
2065 arguments are now treated identically, making the behaviour easier
2066 to describe and understand. For example, slice(None, -10,
2067 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2068 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2069 10, -1).
2070
Georg Brandl278fc502008-07-19 12:46:12 +00002071- Issue #3219: Calling a function with repeated keyword arguments,
2072 f(a=2, a=23), would not cause a syntax error. This was a regression
2073 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002074
Georg Brandl278fc502008-07-19 12:46:12 +00002075- Issue #2862: Make int and float freelist management consistent with
2076 other freelists. Changes their CompactFreeList apis into
2077 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002078

2080-------
2081
Thomas Heller57adf222008-08-14 19:10:48 +00002082- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2083 api functions without holding the GIL, which could lead to a fatal
2084 error when they failed.
2085
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002086- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2095 ForkingPickler.register() to resolve conflict with ctypes.
2096
Vinay Sajip51e65192008-07-18 09:01:10 +00002097- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00002099- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2100 a valid dlerror() message.
2101
Thomas Heller2bad6572008-07-15 17:19:50 +00002102- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2103 incomplete structure was created.
2104

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002111- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2112 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002113 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002114 content-length. The problem had been corrected in the 2.4 branch, but never
2115 merged into trunk.
2116

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002130- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2132
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002133- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002521- On MacOS X it is now possible to install the framework in 64-bit
2522 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002523 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002524
2525 This is controlled by the configure argument ``--with-universal-archs``:
2526
2527 - ``--with-universal-archs=all``: install 4-way universal
2528
2529 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2530
2531 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2532
2533 This option should be used in combination with ``--enable-universalsdk=``.
2534
2535 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 +00002585- Issue #1631171: Re-implement the 'warnings' module in C (the
2586 original Python code has been kept as backup). This will allow for
2587 using the 'warning's machinery in such places as the parser where
2588 use of pure Python code is not possible. Both the ``showarning()``
2589 and ``formatwarning()`` gain an optional 'line' argument which is
2590 not called by default for backwards-compatibility reasons. Setting
2591 ``warnings.showwarning()`` to an implementation that lacks support
2592 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002655- Issue #2550: The approach used by client/server code for obtaining
2656 ports to listen on in network-oriented tests has been refined in an
2657 effort to facilitate running multiple instances of the entire
2658 regression test suite in parallel without issue.
2659 test_support.bind_port() has been fixed such that it will always
2660 return a unique port -- which wasn't always the case with the
2661 previous implementation, especially if socket options had been set
2662 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2663 new implementation of bind_port() will actually raise an exception
2664 if it is passed an AF_INET/SOCK_STREAM socket with either the
2665 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2666 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2667 the socket it's been passed. This currently only applies to
2668 Windows. This option prevents any other sockets from binding to the
2669 host/port we've bound to, thus removing the possibility of the
2670 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2671 when a second SOCK_STREAM socket binds and accepts to a host/port
2672 that's already been bound by another socket. The optional preferred
2673 port parameter to bind_port() has been removed. Under no
2674 circumstances should tests be hard coding ports!
2675
2676 test_support.find_unused_port() has also been introduced, which will
2677 pass a temporary socket object to bind_port() in order to obtain an
2678 unused port. The temporary socket object is then closed and
2679 deleted, and the port is returned. This method should only be used
2680 for obtaining an unused port in order to pass to an external program
2681 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2682 a parameter to a server-oriented class that doesn't give you direct
2683 access to the underlying socket used.
2684
2685 Finally, test_support.HOST has been introduced, which should be used
2686 for the host argument of any relevant socket calls (i.e. bind and
2687 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002688
2689 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002690 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002691 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2692 test_asynchat and test_socket_ssl.
2693
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694 It is now possible for multiple instances of the regression test
2695 suite to run in parallel without issue.

Christian Heimes5224d282008-02-23 15:01:05 +00002970
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002971- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002972 issue 215555 for a discussion.
2973
Eric Smitha73fbe72008-02-23 03:09:44 +00002974- Added the future_builtins module, which contains hex() and oct().
2975 These are the PEP 3127 version of these functions, designed to be
2976 compatible with the hex() and oct() builtins from Python 3.0. They
2977 differ slightly in their output formats from the existing, unchanged
2978 Python 2.6 builtins. The expected usage of the future_builtins
2979 module is:
2980 from future_builtins import hex, oct
2981
Eric Smith7ef40bf2008-02-20 23:34:22 +00002982- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2983 exponents for exponents with absolute value < 100. Follows C99
2984 standard. This is a change on Windows, which would use 3 digits.
2985 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2986 so that any alterations it does to the resulting string will be
2987 available in stringlib/formatter.h (for float.__format__).
2988
Eric Smith5a3c1352008-02-19 13:21:56 +00002989- Implemented PEP 3101, Advanced String Formatting. This adds a new
2990 builtin format(); a format() method for str and unicode; a
2991 __format__() method to object, str, unicode, int, long, float, and
2992 datetime; the class string.Formatter; and the C API
2993 PyObject_Format().
2994
Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Fixed several potential crashes, all caused by specially crafted
2996 __del__ methods exploiting objects in temporarily inconsistent
2997 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002998
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002999- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003000 prevent a possible crash: an Abstract Base Class would try to access
3001 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003002
Georg Brandl3ee81df2008-05-17 18:14:43 +00003003- Fixed repr() and str() of complex numbers with infinity or nan as
3004 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003005
Georg Brandl3ee81df2008-05-17 18:14:43 +00003006- Clear all free lists during a gc.collect() of the highest generation
3007 in order to allow pymalloc to free more arenas. Python may give back
3008 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003009
Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Issue #2045: Fix an infinite recursion triggered when printing a
3011 subclass of collections.defaultdict, if its default_factory is set
3012 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003013
Christian Heimesf75dbef2008-02-08 00:11:31 +00003014- Fixed a minor memory leak in dictobject.c. The content of the free
3015 list was not freed on interpreter shutdown.
3016
Georg Brandl5a7eca12010-03-21 19:29:04 +00003017- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003018 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003019
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3021 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003022 to compact the internal free lists of pre-allocted ints and floats.
3023
Georg Brandl3ee81df2008-05-17 18:14:43 +00003024- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3025 calls. Python expected the return type int but the fork familie
3026 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003027
Georg Brandl3ee81df2008-05-17 18:14:43 +00003028- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3029 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003030
Georg Brandl3ee81df2008-05-17 18:14:43 +00003031- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3032 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003033
Georg Brandl3ee81df2008-05-17 18:14:43 +00003034- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3035 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003036
Georg Brandl3ee81df2008-05-17 18:14:43 +00003037- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3038 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003039
Georg Brandl3ee81df2008-05-17 18:14:43 +00003040- Patch #1473257: generator objects gain a gi_code attribute. This is
3041 the same object as the func_code attribute of the function that
3042 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003043
Georg Brandl3ee81df2008-05-17 18:14:43 +00003044- Issue #1920: "while 0" statements were completely removed by the
3045 compiler, even in the presence of an "else" clause, which is
3046 supposed to be run when the condition is false. Now the compiler
3047 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003048
Guido van Rossumeead05f2008-01-24 18:21:02 +00003049- A few crashers fixed: weakref_in_del.py (issue #1377858);
3050 loosing_dict_ref.py (issue #1303614, test67.py);
3051 borrowed_ref_[34].py (not in tracker).
3052
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003053- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003054 suppressed while an extension is loaded by calling SetErrorMode in
3055 dynload_win.c. The error is still reported properly.
3056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003058 several extension methods and modules do not work without unicode
3059 support.
3060
Georg Brandl26543b12008-01-21 18:36:51 +00003061- Issue #1882: when compiling code from a string, encoding cookies in the
3062 second line of code were not always recognized correctly.
3063
Georg Brandl14404b62008-01-19 19:27:05 +00003064- Issue #1679: "0x" was taken as a valid integer literal.
3065
Georg Brandl6caad7d2008-01-26 14:19:22 +00003066- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003067 added.
3068
Christian Heimesc94e2b52008-01-14 04:13:37 +00003069- sys.float_info / PyFloat_GetInfo: The floating point information
3070 object was converted from a dict to a specialized structseq object.
3071
Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Patch #1816: Added sys.flags structseq. It exposes the status of
3073 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003074
Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- Objects/structseq.c: Implemented new structseq representation. The
3076 patch makes structseqs (e.g. the return value of os.stat) more
3077 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003078
Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Patch #1700288: added a type attribute cache that caches method
3080 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003081
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003082- Bug #1776: __import__() no longer accepts filenames on any platform.
3083 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003084
Georg Brandlaed6c662008-01-07 17:25:53 +00003085- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3086
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3088 envvar and sys.dont_write_bytecode attribute. All these can be set
3089 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003090
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091- Improve some exception messages when Windows fails to load an
3092 extension module. Now we get for example '%1 is not a valid Win32
3093 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003094
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003097- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3098 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003099
Christian Heimes0a8143f2007-12-18 23:22:54 +00003100- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101 and INF. float("nan"), float("inf") and float("-inf") now work on
3102 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003103
Georg Brandl3ee81df2008-05-17 18:14:43 +00003104- Compiler now generates simpler and faster code for dictionary
3105 literals. The oparg for BUILD_MAP now indicates an estimated
3106 dictionary size. There is a new opcode, STORE_MAP, for adding
3107 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003108
Georg Brandl3ee81df2008-05-17 18:14:43 +00003109- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003114- Issue #1538: Avoid copying string in split/rsplit if the split char
3115 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003116
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003117- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003118 SystemError.
3119
Nick Coghlanef01d822007-12-03 12:55:17 +00003120- PEP 366: Allow explicit relative imports when executing modules

3122 __package__ attribute.
3123
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124- Issue #1402: Fix a crash on exit, when another thread is still
3125 running, and if the deallocation of its frames somehow calls the
3126 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003127

Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Patch #1739468: Directories and zipfiles containing a __main__.py
3137 file can now be directly executed by passing their name to the
3138 interpreter. The directory/zipfile is automatically inserted as the
3139 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003140
Georg Brandl3ee81df2008-05-17 18:14:43 +00003141- Issue #1265: Fix a problem with sys.settrace, if the tracing
3142 function uses a generator expression when at the same time the
3143 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003144
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003145- sets and frozensets now have an isdisjoint() method.
3146
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003147- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00003149- Fix warnings found by the new version of the Coverity checker.
3150
Georg Brandl5a7eca12010-03-21 19:29:04 +00003151- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003152 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3153 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003154
Georg Brandl3ee81df2008-05-17 18:14:43 +00003155- Issue #1686386: Tuple's tp_repr did not take into account the
3156 possibility of having a self-referential tuple, which is possible
3157 from C code. Nor did object's tp_str consider that a type's tp_str
3158 could do something that could lead to an inifinite recursion.
3159 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3160 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003161
Georg Brandl3ee81df2008-05-17 18:14:43 +00003162- Issue #1164: It was possible to trigger deadlock when using the
3163 'print' statement to write to a file since the GIL was not released
3164 as needed. Now PyObject_Print() does the right thing along with
3165 various tp_print implementations of the built-in types and those in
3166 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003167
Georg Brandl3ee81df2008-05-17 18:14:43 +00003168- Issue #1147: Exceptions were directly allowing string exceptions in
3169 their throw() method even though string exceptions no longer
3170 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003171
Georg Brandl3ee81df2008-05-17 18:14:43 +00003172- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003175- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003176 PyObject_Call() never calling back out to Python code to trigger
3177 recursion depth updates/checks. Required the creation of a static
3178 RuntimeError instance in case normalizing an exception put the
3179 recursion check value past its limit. Fixes crashers
3180 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003181

Neal Norwitz0ac60192007-05-27 04:08:54 +00003195- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003196 __*__ attributes. (Some already existed, e.g., __doc__ and
3197 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003198
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003199- Add -3 option to the interpreter to warn about features that are
3200 deprecated and will be changed/removed in Python 3.0.
3201
Georg Brandl2134e752007-05-21 20:34:16 +00003202- Patch #1686487: you can now pass any mapping after '**' in function
3203 calls.
3204
Collin Winter62903052007-05-18 23:11:24 +00003205- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003206 "except E as target:". This is to provide forwards compatibility
3207 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003208
Brett Cannon229cee22007-05-05 01:34:02 +00003209- Deprecate BaseException.message as per PEP 352.
3210
Georg Brandl3ee81df2008-05-17 18:14:43 +00003211- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003212 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003214- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003215 setting a plain string, ie don't expand to single letter identifiers.

Raymond Hettinger13936692007-04-11 18:40:58 +00003217- Request #1191699: Slices can now be pickled.
3218
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003219- Request #1193128: str.translate() now allows a None argument for
3220 translations that only remove characters without re-mapping the
3221 remaining characters.
3222
Georg Brandl5cb76c12007-03-21 09:00:39 +00003223- Patch #1682205: a TypeError while unpacking an iterable is no longer

3227
Guido van Rossum143b5642007-03-23 04:58:42 +00003228- Bug #1683368: The object.__init__() and object.__new__() methods are
3229 now stricter in rejecting excess arguments. The only time when
3230 either allows excess arguments is when it is not overridden and the
3231 other one is. For backwards compatibility, when both are
3232 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003233 warning later). Also, type.__init__() insists on the same signature
3234 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003235
Georg Brandl3ee81df2008-05-17 18:14:43 +00003236- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3237 object to complex using its __complex__() method before falling back
3238 to the __float__() method. Therefore, the functions in the cmath
3239 module now can operate on objects that define a __complex__()
3240 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003258- Bug #1678647: write a newline after printing an exception in any
3259 case, even when converting the value to a string failed.
3260
Georg Brandl871f1bc2007-03-12 13:17:36 +00003261- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262 its argument, if it exists. If not, it will work like before. This
3263 allows customizing the output of dir() in the presence of a
3264 __getattr__().

3274 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003275
Georg Brandlaa2321b2007-03-07 00:40:28 +00003276- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277 makes the filenames the warning module prints much more sensible
3278 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003279

Georg Brandl0fca97a2007-03-05 22:28:08 +00003291- Patch #1674228: when assigning a slice (old-style), check for the
3292 sq_ass_slice instead of the sq_slice slot.
3293
Georg Brandl3ee81df2008-05-17 18:14:43 +00003294- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00003346- Bug #1545497: when given an explicit base, int() did ignore NULs
3347 embedded in the string to convert.
3348
Georg Brandl846f73a2006-10-08 07:11:54 +00003349- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003397 generator expressions (x for x, in ... ) works again. Fixing this
3398 problem required changing the .pyc magic number. This means that
3399 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003829 AttributeError instead of an IOError when the server's response
3830 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003831

Georg Brandl92a6bae2007-03-13 17:43:32 +00003863- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003864 are set for invalid interpolation sequences that would lead to
3865 errors on reading back those values.

3908 returned string up to the first NUL character.
3909

3919
Georg Brandl3ee81df2008-05-17 18:14:43 +00003920- unittest now verifies more of its assumptions. In particular,
3921 TestCase and TestSuite subclasses (not instances) are no longer
3922 accepted in TestSuite.addTest(). This should cause no
3923 incompatibility since it never made sense with ordinary subclasses
3924 -- the failure just occurred later, with a more cumbersome
3925 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004206- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4207 with RFC 3207 and forgets any knowledge obtained from the server not
4208 obtained from the TLS negotiation itself. Patch contributed by Bill
4209 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004210
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004212 that the SMTP.starttls() caller no longer needs to call ehlo()
4213 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004214 does not claim to support starttls. Adds the
4215 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4296 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4297 silently miscode subclasses of those types. Now, it raises a
4298 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004299

Georg Brandl3ee81df2008-05-17 18:14:43 +00004314 time so that opening a database previously created with the DB_DUP
4315 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4316 opens. Specifically: dictionary assignment to a DB object will
4317 replace all values for a given key when the database allows
4318 duplicate values. DB users should use DB.put(k, v) when they want
4319 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004320

4326 characters with ASCII value less than 32. Also, it correctly quotes
4327 dots only if they occur on a single line, as opposed to the previous
4328 behavior of quoting dots if they are the second character of any
4329 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004330

Georg Brandl3ee81df2008-05-17 18:14:43 +00004735- Removed the macfs module. It had been deprecated since Python 2.5.
