22 processing: any non-float non-integer argument is now converted to
23 an integer (if possible) using its __int__ method. Previously, only
24 small arguments were treated this way; larger arguments (those whose
25 __int__ was outside the range of a C long) would produce a TypeError.
26
Benjamin Petersonc218ce82010-04-16 22:43:53 +000027- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

49
50- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
51 embedders of the interpreter to set sys.argv without also modifying
52 sys.path. This helps fix `CVE-2008-5983
53 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

104 ASCII with backslashreplace error handler if str(value) failed
105
Mark Dickinson1cdfa5f2010-05-04 14:30:32 +0000106- Issue #8567: Fix precedence of signals in Decimal module: when a
107 Decimal operation raises multiple signals and more than one of those
108 signals is trapped, the specification determines the order in which
109 the signals should be handled. In many cases this order wasn't
110 being followed, leading to the wrong Python exception being raised.

122 not just SIGCHLD.
123
Victor Stinner5b4d7ff2010-05-15 21:03:33 +0000124- Issue #8577: distutils.sysconfig.get_python_inc() now makes a difference
Tarek Ziadé68ca24b2010-04-30 12:18:51 +0000125 between the build dir and the source dir when looking for "python.h" or

161 a non-infinite timeout. Also make that method friendlier with applications
162 wanting to continue using the socket in clear-text mode, by disabling
163 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.

1254 do an explicit seek to the end of file (so that e.g. tell() returns the
1255 file size rather than 0). This is consistent with the behaviour of the
1256 traditional 2.x file object.

1287 zipimport (or any other conformant PEP 302 loader). Original patch by
1288 Alexander Belopolsky.
1289
1290- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1291 302 conformant loader) will now work correctly in most cases (they
1292 are still subject to the constraints that exist for all code running
1293 from inside a module loaded via a PEP 302 loader and attempting to

1452What's New in Python 2.6.1
1453==========================
1454
1455*Release date: 04-Dec-2008*
1456
1457Core and Builtins
1458-----------------
1459
1460- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1461 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1462 instead of throwing a MemoryError.
1463
1464- Issue #4367: Python would segfault during compiling when the unicodedata
1465 module couldn't be imported and \N escapes were present.
1466
1467- Issue #4348: Some bytearray methods returned that didn't cause any change to
1468 the bytearray, returned the same bytearray instead of a copy.
1469
1470- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1471
1472- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1473
1474- Issue #4048: The parser module now correctly validates relative imports.
1475
1476- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1477 exec statement.
1478
1479- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1480 method does not return iterators for the 4th and 5th items.
1481
1482- Issue #4209: Enabling unicode_literals and the print_function in the same
1483 __future__ import didn't work.
1484
1485- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1486 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1487 really executed because I cannot move to such directory on win2k)
1488
1489- Issue #4069: When set.remove(element) is used with a set element, the element
1490 is temporarily replaced with an equivalent frozenset. But the eventual
1491 KeyError would always report the empty frozenset([]) as the missing key. Now
1492 it correctly refers to the initial element.
1493
1494- Fixed C99 style comments in several files. Python is now C89 compatible
1495 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001642- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1643
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001644- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1645 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1646 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1647 ``printf`` function, whereas PyString_FromFormat has an independent
1648 implementation and uses "%zd" on all platforms for size_t values.
1649 This makes a difference on win64, where ``printf`` needs "%Id" to display
1650 64bit values.
1651
Benjamin Peterson97179b02008-09-09 20:55:01 +00001652- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1653 error.

1656 object; previously an int would be returned for small values. the __long__
1657 method is allowed to return either an int or a long, but the behaviour of
1658 float objects should not change to respect backward compatibility.
1659
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001660- Issue #3751: str.rpartition would perform a left-partition when called with
1661 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001666 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001667 was correctly parsed but parsing of subsequent arguments failed.
1668
Vinay Sajip35e3b032008-09-01 14:33:59 +00001669- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001670 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1671 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1672 when given a tuple of classes as second argument, were looking up
1673 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1674 type object.
1675
Neal Norwitz18aa3882008-08-24 05:04:52 +00001676- Fix crashes on memory allocation failure found with failmalloc.

1745 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1746 for catch_warnings() also led to an improvement in the raising of a

1816-----------------
1817
Guido van Rossumf8402962008-08-20 15:01:50 +00001818- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1819 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1820 extensions do not automatically benefit from the class attribute
1821 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1822 to their tp_flags field if they care. This is a backwards
1823 compatibility feature; in 3.0, all types will use the cache by
1824 default.
1825
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001826- Keyword arguments can now follow starred arguments. (``f(a, *args,
1827 keyword=23)`` is now valid syntax.)
1828
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001829- ctypes function pointers that are COM methods have a boolean True
1830 value again.
1831
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001832- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1833 by denying s# to parse objects that have a releasebuffer procedure,
1834 and introducing s*.
1835
Georg Brandl1e13ea92008-08-11 09:07:59 +00001836- Issue #3537: Fix an assertion failure when an empty but presized dict
1837 object was stored in the freelist.
1838
Mark Dickinsonb6467572008-08-04 21:30:09 +00001839- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1840 ValueError consistently across platforms.
1841
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001842- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1843 (64bit Unix, for example), unichr() would truncate its argument and return
1844 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1845
Neal Norwitze7d8be82008-07-31 17:17:14 +00001846- Apply security patches from Apple.
1847
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001848- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1849 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1850
Antoine Pitrou92f82162008-07-25 22:22:08 +00001851- Issue #1819: function calls with several named parameters are now on
1852 average 35% faster (as measured by pybench).
1853
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001854- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1855 the python debugger steps into a class statement: the free variables (local
1856 variables defined in an outer scope) would be deleted from the outer scope.
1857
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001858- Issue #2620: Overflow checking when allocating or reallocating memory
1859 was not always being done properly in some python types and extension
1860 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1861 all been updated to perform better checks and places in the code that
1862 would previously leak memory on the error path when such an allocation
1863 failed have been fixed.

Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001873- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1874 version reported by these tools does not necessarily follow the python
1875 version numbering scheme, so the module is less strict when parsing it.
1876
Nick Coghlanf70385a2008-08-18 12:42:46 +00001877- Issue #2235: Added Py3k warnings for types which will become unhashable
1878 under the stricter __hash__ inheritance rules in 3.0. Several types
1879 which did not meet the rules for hash invariants and were already
1880 unhashable in 3.0 have now been explicitly flagged as unhashable in
1881 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1882 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1883
Brett Cannon88f801d2008-08-18 00:46:22 +00001884- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1894 by using 's*' instead of 't#'.
1895
Jesus Cea585ad8a2009-07-02 15:37:21 +00001896- Issue #2222: Fixed reference leak when occurred os.rename()

1907
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001908- Issue #2676: in the email package, content-type parsing was hanging on

1910 regular expression.
1911
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001912- Issue #3476: binary buffered reading through the new "io" library is now
1913 thread-safe.
1914
Brett Cannonbf3157b2008-08-14 05:00:03 +00001915- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1916 since mimetools itself is deprecated. Because modules are cached, all
1917 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1918
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001919- Issue #3134: shutil referenced undefined WindowsError symbol.

1925 version that did not raise a DeprecationWarning under -3.
1926

1931 to _sre.compile() will now be rejected. This should not affect anybody
1932 since the re.compile() function never generates invalid re-bytecode.
1933
Skip Montanaroa032bf42008-08-08 22:52:51 +00001934- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1935 upon first access it can be automatically initialized from the csv file if
1936 it wasn't initialized during instantiation.
1937
Brett Cannon3aa2a492008-08-06 22:28:09 +00001938- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1939 the reload() built-in has been removed.
1940
Brett Cannon7e30b672008-08-04 21:52:25 +00001941- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001942 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1950 raised an AttributeError.
1951
Benjamin Peterson01a24322008-07-28 23:35:27 +00001952- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001953 asking for a specific length. This problem only affected files opened
1954 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001955

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001979- Issue #3394: zipfile.writestr sets external attributes when passed a
1980 file name rather than a ZipInfo instance, so files are extracted with
1981 mode 0600 rather than 000 under Unix.
1982
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001983- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1996 interaction with the tp_hash slot (added in 2.6b2) are now documented
1997
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001998- Issue #643841: The language reference now provides more detailed
1999 coverage of the lookup process for special methods. The disclaimers
2000 regarding lack of coverage of new-style classes have also been

2005================================
2006
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002007*Release date: 17-Jul-2008*
2008
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002009Core and Builtins
2010-----------------
2011
Georg Brandl3e483f62008-07-16 22:57:41 +00002012- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2013 its methods now allow for items objects that can be converted to
2014 an integer using operator.index().
2015
Mark Dickinson64b7e502008-07-16 09:40:03 +00002016- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2017 produced a ValueError instead of giving the correct float.
2018
Eric Smitha5fa5a22008-07-16 00:11:49 +00002019- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2020 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2021
Mark Dickinson7103aa42008-07-15 19:08:33 +00002022- Issue #3008: the float type has a new instance method 'float.hex'
2023 and a new class method 'float.fromhex' to convert floating-point
2024 numbers to and from hexadecimal strings, respectively.
2025
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002026- Issue #2235: __hash__ is once again inherited by default. To allow
2027 collections.Hashable to remain meaningful in the presence of the
2028 default hash implementation (object.__hash__), it is now possible
2029 to explicit block inheritance of hash by setting __hash__=None at
2030 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2031 level.
2032
Nick Coghlanb028f502008-07-13 14:52:36 +00002033- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2034 the parent module cannot be found while performing an absolute import.
2035 This means that an incorrectly defined __package__ attribute will
2036 now only prevent relative imports in that module rather than causing
2037 all imports from that module to fail.
2038
Nick Coghlan14ff9942008-07-08 14:21:42 +00002039- Issue #2517: Allow unicode messages in Exceptions again by correctly
2040 bypassing the instance dictionary when looking up __unicode__ on
2041 new-style classes.
2042
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002043- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2044 set to a custom object whose write() method happens to install
2045 another file in sys.stdout.
2046
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002047- Issue #3088: Corrected a race condition in classes derived from
2048 threading.local: the first member set by a thread could be saved in
2049 another thread's dictionary.
2050
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002051- Issue #3004: Minor change to slice.indices(): the start and stop
2052 arguments are now treated identically, making the behaviour easier
2053 to describe and understand. For example, slice(None, -10,
2054 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2055 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2056 10, -1).
2057
Georg Brandl278fc502008-07-19 12:46:12 +00002058- Issue #3219: Calling a function with repeated keyword arguments,
2059 f(a=2, a=23), would not cause a syntax error. This was a regression
2060 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002061
Georg Brandl278fc502008-07-19 12:46:12 +00002062- Issue #2862: Make int and float freelist management consistent with
2063 other freelists. Changes their CompactFreeList apis into
2064 ClearFreeList apis and calls them via gc.collect().

2067-------
2068
Thomas Heller57adf222008-08-14 19:10:48 +00002069- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2070 api functions without holding the GIL, which could lead to a fatal
2071 error when they failed.
2072
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002073- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2083
Vinay Sajip51e65192008-07-18 09:01:10 +00002084- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller2bad6572008-07-15 17:19:50 +00002089- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2090 incomplete structure was created.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002098- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2099 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002100 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002101 content-length. The problem had been corrected in the 2.4 branch, but never
2102 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002117- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2119
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002120- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002508- On MacOS X it is now possible to install the framework in 64-bit
2509 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002510 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002511
2512 This is controlled by the configure argument ``--with-universal-archs``:
2513
2514 - ``--with-universal-archs=all``: install 4-way universal
2515
2516 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2517
2518 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2519
2520 This option should be used in combination with ``--enable-universalsdk=``.
2521
2522 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 +00002572- Issue #1631171: Re-implement the 'warnings' module in C (the
2573 original Python code has been kept as backup). This will allow for
2574 using the 'warning's machinery in such places as the parser where
2575 use of pure Python code is not possible. Both the ``showarning()``
2576 and ``formatwarning()`` gain an optional 'line' argument which is
2577 not called by default for backwards-compatibility reasons. Setting
2578 ``warnings.showwarning()`` to an implementation that lacks support
2579 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002642- Issue #2550: The approach used by client/server code for obtaining
2643 ports to listen on in network-oriented tests has been refined in an
2644 effort to facilitate running multiple instances of the entire
2645 regression test suite in parallel without issue.
2646 test_support.bind_port() has been fixed such that it will always
2647 return a unique port -- which wasn't always the case with the
2648 previous implementation, especially if socket options had been set
2649 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2650 new implementation of bind_port() will actually raise an exception
2651 if it is passed an AF_INET/SOCK_STREAM socket with either the
2652 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2653 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2654 the socket it's been passed. This currently only applies to
2655 Windows. This option prevents any other sockets from binding to the
2656 host/port we've bound to, thus removing the possibility of the
2657 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2658 when a second SOCK_STREAM socket binds and accepts to a host/port
2659 that's already been bound by another socket. The optional preferred
2660 port parameter to bind_port() has been removed. Under no
2661 circumstances should tests be hard coding ports!
2662
2663 test_support.find_unused_port() has also been introduced, which will
2664 pass a temporary socket object to bind_port() in order to obtain an
2665 unused port. The temporary socket object is then closed and
2666 deleted, and the port is returned. This method should only be used
2667 for obtaining an unused port in order to pass to an external program
2668 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2669 a parameter to a server-oriented class that doesn't give you direct
2670 access to the underlying socket used.
2671
2672 Finally, test_support.HOST has been introduced, which should be used
2673 for the host argument of any relevant socket calls (i.e. bind and
2674 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002675
2676 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002677 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002678 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2679 test_asynchat and test_socket_ssl.
2680
Georg Brandl3ee81df2008-05-17 18:14:43 +00002681 It is now possible for multiple instances of the regression test
2682 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002736- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002737 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2738 Plane. This affected raw unicode literals and the
2739 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2740 this case, like normal unicode literals and the 'unicode-escape'
2741 codec.

2960
Eric Smitha73fbe72008-02-23 03:09:44 +00002961- Added the future_builtins module, which contains hex() and oct().
2962 These are the PEP 3127 version of these functions, designed to be
2963 compatible with the hex() and oct() builtins from Python 3.0. They
2964 differ slightly in their output formats from the existing, unchanged
2965 Python 2.6 builtins. The expected usage of the future_builtins
2966 module is:

2968
Eric Smith7ef40bf2008-02-20 23:34:22 +00002969- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2970 exponents for exponents with absolute value < 100. Follows C99
2971 standard. This is a change on Windows, which would use 3 digits.
2972 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2973 so that any alterations it does to the resulting string will be
2974 available in stringlib/formatter.h (for float.__format__).
2975
Eric Smith5a3c1352008-02-19 13:21:56 +00002976- Implemented PEP 3101, Advanced String Formatting. This adds a new
2977 builtin format(); a format() method for str and unicode; a
2978 __format__() method to object, str, unicode, int, long, float, and
2979 datetime; the class string.Formatter; and the C API
2980 PyObject_Format().
2981
Georg Brandl3ee81df2008-05-17 18:14:43 +00002982- Fixed several potential crashes, all caused by specially crafted
2983 __del__ methods exploiting objects in temporarily inconsistent
2984 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002993- Clear all free lists during a gc.collect() of the highest generation
2994 in order to allow pymalloc to free more arenas. Python may give back
2995 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002996
Georg Brandl3ee81df2008-05-17 18:14:43 +00002997- Issue #2045: Fix an infinite recursion triggered when printing a
2998 subclass of collections.defaultdict, if its default_factory is set
2999 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003027- Patch #1473257: generator objects gain a gi_code attribute. This is
3028 the same object as the func_code attribute of the function that
3029 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003030
Georg Brandl3ee81df2008-05-17 18:14:43 +00003031- Issue #1920: "while 0" statements were completely removed by the
3032 compiler, even in the presence of an "else" clause, which is
3033 supposed to be run when the condition is false. Now the compiler
3034 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003035
Guido van Rossumeead05f2008-01-24 18:21:02 +00003036- A few crashers fixed: weakref_in_del.py (issue #1377858);

3043
Georg Brandl3ee81df2008-05-17 18:14:43 +00003044- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003045 several extension methods and modules do not work without unicode
3046 support.
3047
Georg Brandl26543b12008-01-21 18:36:51 +00003048- Issue #1882: when compiling code from a string, encoding cookies in the

3052
Georg Brandl6caad7d2008-01-26 14:19:22 +00003053- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003054 added.
3055
Christian Heimesc94e2b52008-01-14 04:13:37 +00003056- sys.float_info / PyFloat_GetInfo: The floating point information
3057 object was converted from a dict to a specialized structseq object.
3058
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Patch #1816: Added sys.flags structseq. It exposes the status of
3060 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003061
Georg Brandl3ee81df2008-05-17 18:14:43 +00003062- Objects/structseq.c: Implemented new structseq representation. The
3063 patch makes structseqs (e.g. the return value of os.stat) more
3064 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003065
Georg Brandl3ee81df2008-05-17 18:14:43 +00003066- Patch #1700288: added a type attribute cache that caches method
3067 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003068
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003069- Bug #1776: __import__() no longer accepts filenames on any platform.

3075 envvar and sys.dont_write_bytecode attribute. All these can be set
3076 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003077
Georg Brandl3ee81df2008-05-17 18:14:43 +00003078- Improve some exception messages when Windows fails to load an
3079 extension module. Now we get for example '%1 is not a valid Win32
3080 application' instead of 'error code 193'.

3137
Georg Brandl5a7eca12010-03-21 19:29:04 +00003138- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3140 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003141
Georg Brandl3ee81df2008-05-17 18:14:43 +00003142- Issue #1686386: Tuple's tp_repr did not take into account the
3143 possibility of having a self-referential tuple, which is possible
3144 from C code. Nor did object's tp_str consider that a type's tp_str
3145 could do something that could lead to an inifinite recursion.
3146 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3147 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003148
Georg Brandl3ee81df2008-05-17 18:14:43 +00003149- Issue #1164: It was possible to trigger deadlock when using the
3150 'print' statement to write to a file since the GIL was not released
3151 as needed. Now PyObject_Print() does the right thing along with
3152 various tp_print implementations of the built-in types and those in
3153 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003154
Georg Brandl3ee81df2008-05-17 18:14:43 +00003155- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00003163 PyObject_Call() never calling back out to Python code to trigger
3164 recursion depth updates/checks. Required the creation of a static
3165 RuntimeError instance in case normalizing an exception put the
3166 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00003210- Patch #1682205: a TypeError while unpacking an iterable is no longer
3211 masked by a generic one with the message "unpack non-sequence".

Guido van Rossum143b5642007-03-23 04:58:42 +00003215- Bug #1683368: The object.__init__() and object.__new__() methods are
3216 now stricter in rejecting excess arguments. The only time when
3217 either allows excess arguments is when it is not overridden and the
3218 other one is. For backwards compatibility, when both are
3219 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003220 warning later). Also, type.__init__() insists on the same signature
3221 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003223- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3224 object to complex using its __complex__() method before falling back
3225 to the __float__() method. Therefore, the functions in the cmath
3226 module now can operate on objects that define a __complex__()
3227 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003245- Bug #1678647: write a newline after printing an exception in any
3246 case, even when converting the value to a string failed.
3247
Georg Brandl871f1bc2007-03-12 13:17:36 +00003248- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003249 its argument, if it exists. If not, it will work like before. This
3250 allows customizing the output of dir() in the presence of a
3251 __getattr__().

3261 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003262
Georg Brandlaa2321b2007-03-07 00:40:28 +00003263- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264 makes the filenames the warning module prints much more sensible
3265 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003278- Patch #1674228: when assigning a slice (old-style), check for the
3279 sq_ass_slice instead of the sq_slice slot.
3280
Georg Brandl3ee81df2008-05-17 18:14:43 +00003281- When printing an unraisable error, don't print exceptions. before
3282 the name. This duplicates the behavior whening normally printing
3283 exceptions.

3292 created a weakref on itself during a __del__ call for new-style
3293 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00003333- Bug #1545497: when given an explicit base, int() did ignore NULs
3334 embedded in the string to convert.
3335
Georg Brandl846f73a2006-10-08 07:11:54 +00003336- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003384 generator expressions (x for x, in ... ) works again. Fixing this
3385 problem required changing the .pyc magic number. This means that
3386 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003425- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00004189- The implementation of UnicodeError objects has been simplified
4190 (start and end attributes are now stored directly as Py_ssize_t
4191 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4194 with RFC 3207 and forgets any knowledge obtained from the server not
4195 obtained from the TLS negotiation itself. Patch contributed by Bill
4196 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004197
Georg Brandl3ee81df2008-05-17 18:14:43 +00004198- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004199 that the SMTP.starttls() caller no longer needs to call ehlo()
4200 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004201 does not claim to support starttls. Adds the
4202 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4203 Fenner.

4283 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4284 silently miscode subclasses of those types. Now, it raises a
4285 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004286

Georg Brandl3ee81df2008-05-17 18:14:43 +00004301 time so that opening a database previously created with the DB_DUP
4302 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4303 opens. Specifically: dictionary assignment to a DB object will
4304 replace all values for a given key when the database allows
4305 duplicate values. DB users should use DB.put(k, v) when they want
4306 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004307

4313 characters with ASCII value less than 32. Also, it correctly quotes
4314 dots only if they occur on a single line, as opposed to the previous
4315 behavior of quoting dots if they are the second character of any
4316 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004317

Georg Brandl3ee81df2008-05-17 18:14:43 +00004722- Removed the macfs module. It had been deprecated since Python 2.5.
4723 This lead to the deprecation of macostools.touched() as it relied
4724 solely on macfs and was a no-op under OS X.
