1313What's New in Python 2.6.1
1314==========================
1315
1316*Release date: 04-Dec-2008*
1317
1318Core and Builtins
1319-----------------
1320
1321- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1322 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1323 instead of throwing a MemoryError.
1324
1325- Issue #4367: Python would segfault during compiling when the unicodedata
1326 module couldn't be imported and \N escapes were present.
1327
1328- Issue #4348: Some bytearray methods returned that didn't cause any change to
1329 the bytearray, returned the same bytearray instead of a copy.
1330
1331- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1332
1333- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1334
1335- Issue #4048: The parser module now correctly validates relative imports.
1336
1337- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1338 exec statement.

1341 method does not return iterators for the 4th and 5th items.
1342
1343- Issue #4209: Enabling unicode_literals and the print_function in the same
1344 __future__ import didn't work.
1345
1346- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1347 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1348 really executed because I cannot move to such directory on win2k)
1349
1350- Issue #4069: When set.remove(element) is used with a set element, the element
1351 is temporarily replaced with an equivalent frozenset. But the eventual
1352 KeyError would always report the empty frozenset([]) as the missing key. Now
1353 it correctly refers to the initial element.
1354
1355- Fixed C99 style comments in several files. Python is now C89 compatible
1356 again.

1504
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001505- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1506 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1507 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1508 ``printf`` function, whereas PyString_FromFormat has an independent
1509 implementation and uses "%zd" on all platforms for size_t values.
1510 This makes a difference on win64, where ``printf`` needs "%Id" to display
1511 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001531 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1532 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1534 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1535 type object.

1604
Brett Cannon1eaf0742008-09-02 01:25:16 +00001605- Issue 3602: Moved test.test_support.catch_warning() to
1606 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1607 for catch_warnings() also led to an improvement in the raising of a
1608 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001630- Issue #2975: When compiling several extension modules with Visual Studio 2008
1631 from the same python interpreter, some environment variables would grow
1632 without limit.
1633
Benjamin Peterson37346b22008-08-23 20:27:43 +00001634- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001671What's New in Python 2.6 beta 3?
1672================================
1673
Barry Warsaw07a4a382008-08-21 01:15:08 +00001674*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001675
1676Core and Builtins
1677-----------------
1678
Guido van Rossumf8402962008-08-20 15:01:50 +00001679- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1680 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1681 extensions do not automatically benefit from the class attribute
1682 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1683 to their tp_flags field if they care. This is a backwards
1684 compatibility feature; in 3.0, all types will use the cache by
1685 default.
1686
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001687- Keyword arguments can now follow starred arguments. (``f(a, *args,
1688 keyword=23)`` is now valid syntax.)
1689
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001690- ctypes function pointers that are COM methods have a boolean True
1691 value again.
1692
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001693- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1694 by denying s# to parse objects that have a releasebuffer procedure,
1695 and introducing s*.
1696
Georg Brandl1e13ea92008-08-11 09:07:59 +00001697- Issue #3537: Fix an assertion failure when an empty but presized dict
1698 object was stored in the freelist.
1699
Mark Dickinsonb6467572008-08-04 21:30:09 +00001700- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1701 ValueError consistently across platforms.
1702
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001703- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1704 (64bit Unix, for example), unichr() would truncate its argument and return
1705 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1706
Neal Norwitze7d8be82008-07-31 17:17:14 +00001707- Apply security patches from Apple.
1708
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001709- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1710 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1711
Antoine Pitrou92f82162008-07-25 22:22:08 +00001712- Issue #1819: function calls with several named parameters are now on
1713 average 35% faster (as measured by pybench).
1714
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001715- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1716 the python debugger steps into a class statement: the free variables (local
1717 variables defined in an outer scope) would be deleted from the outer scope.
1718
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001719- Issue #2620: Overflow checking when allocating or reallocating memory
1720 was not always being done properly in some python types and extension
1721 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1722 all been updated to perform better checks and places in the code that
1723 would previously leak memory on the error path when such an allocation
1724 failed have been fixed.
1725
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001726Library
1727-------
1728
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001729- Issue #3612: Added some missing basic types in ctypes.wintypes.
1730
Benjamin Petersone977ad42008-08-20 01:42:01 +00001731- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1732 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1733
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001734- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1735 version reported by these tools does not necessarily follow the python
1736 version numbering scheme, so the module is less strict when parsing it.
1737
Nick Coghlanf70385a2008-08-18 12:42:46 +00001738- Issue #2235: Added Py3k warnings for types which will become unhashable
1739 under the stricter __hash__ inheritance rules in 3.0. Several types
1740 which did not meet the rules for hash invariants and were already
1741 unhashable in 3.0 have now been explicitly flagged as unhashable in
1742 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1743 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1744
Brett Cannon88f801d2008-08-18 00:46:22 +00001745- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1749
Brett Cannon46225e72008-08-18 00:36:52 +00001750- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001752- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1753
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001754- Issue #3575: Incremental decoder's decode function now takes bytearray
1755 by using 's*' instead of 't#'.
1756
Jesus Cea585ad8a2009-07-02 15:37:21 +00001757- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001758 fails unicode conversion on 2nd parameter. (windows only)
1759
Facundo Batista94f243a2008-08-17 03:38:39 +00001760- Issue 2464. urllib2 now supports a malformation in the URL received
1761 in a redirect.
1762
Brett Cannonabe423e2008-08-16 21:47:07 +00001763- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001764 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001765
Facundo Batistaeb90b782008-08-16 14:44:07 +00001766- Issue #2776: fixed small issue when handling an URL with double slash
1767 after a 302 response in the case of not going through a proxy.
1768
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001769- Issue #2676: in the email package, content-type parsing was hanging on
1770 pathological input because of quadratic or exponential behaviour of a
1771 regular expression.
1772
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001773- Issue #3476: binary buffered reading through the new "io" library is now
1774 thread-safe.
1775
Brett Cannonbf3157b2008-08-14 05:00:03 +00001776- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1777 since mimetools itself is deprecated. Because modules are cached, all
1778 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1779
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001780- Issue #3134: shutil referenced undefined WindowsError symbol.
1781
Robert Schuppenies14646332008-08-10 11:01:53 +00001782- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1783 menu entries were not deleted.
1784
Brett Cannon83e81842008-08-09 23:30:55 +00001785- Copied the implementation of reduce() to _functools.reduce() to have a
1786 version that did not raise a DeprecationWarning under -3.
1787
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001788- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1789 a MemoryError rather than silently stop the iteration.
1790
Guido van Rossum59ce9012008-08-09 14:55:34 +00001791- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1792 to _sre.compile() will now be rejected. This should not affect anybody
1793 since the re.compile() function never generates invalid re-bytecode.
1794
Skip Montanaroa032bf42008-08-08 22:52:51 +00001795- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00001799- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1800 the reload() built-in has been removed.
1801

Antoine Pitroude781a42008-08-09 12:43:23 +00001814 asking for a specific length. This problem only affected files opened
1815 using the new "io" module, not the built-in open() function.

1842 mode 0600 rather than 000 under Unix.
1843
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001844- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1878 produced a ValueError instead of giving the correct float.
1879
Eric Smitha5fa5a22008-07-16 00:11:49 +00001880- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1881 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1882
Mark Dickinson7103aa42008-07-15 19:08:33 +00001883- Issue #3008: the float type has a new instance method 'float.hex'
1884 and a new class method 'float.fromhex' to convert floating-point
1885 numbers to and from hexadecimal strings, respectively.
1886
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001887- Issue #2235: __hash__ is once again inherited by default. To allow
1888 collections.Hashable to remain meaningful in the presence of the
1889 default hash implementation (object.__hash__), it is now possible
1890 to explicit block inheritance of hash by setting __hash__=None at
1891 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1892 level.
1893
Nick Coghlanb028f502008-07-13 14:52:36 +00001894- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1895 the parent module cannot be found while performing an absolute import.
1896 This means that an incorrectly defined __package__ attribute will
1897 now only prevent relative imports in that module rather than causing
1898 all imports from that module to fail.
1899
Nick Coghlan14ff9942008-07-08 14:21:42 +00001900- Issue #2517: Allow unicode messages in Exceptions again by correctly

1910 another thread's dictionary.
1911
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001912- Issue #3004: Minor change to slice.indices(): the start and stop
1913 arguments are now treated identically, making the behaviour easier
1914 to describe and understand. For example, slice(None, -10,
1915 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1916 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1917 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00001919- Issue #3219: Calling a function with repeated keyword arguments,
1920 f(a=2, a=23), would not cause a syntax error. This was a regression
1921 from 2.4 caused by the switch to the new compiler.

1960 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001961 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00002433- Issue #1631171: Re-implement the 'warnings' module in C (the
2434 original Python code has been kept as backup). This will allow for
2435 using the 'warning's machinery in such places as the parser where
2436 use of pure Python code is not possible. Both the ``showarning()``
2437 and ``formatwarning()`` gain an optional 'line' argument which is
2438 not called by default for backwards-compatibility reasons. Setting
2439 ``warnings.showwarning()`` to an implementation that lacks support
2440 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002503- Issue #2550: The approach used by client/server code for obtaining
2504 ports to listen on in network-oriented tests has been refined in an
2505 effort to facilitate running multiple instances of the entire
2506 regression test suite in parallel without issue.
2507 test_support.bind_port() has been fixed such that it will always
2508 return a unique port -- which wasn't always the case with the
2509 previous implementation, especially if socket options had been set
2510 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2511 new implementation of bind_port() will actually raise an exception
2512 if it is passed an AF_INET/SOCK_STREAM socket with either the
2513 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2514 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2515 the socket it's been passed. This currently only applies to
2516 Windows. This option prevents any other sockets from binding to the
2517 host/port we've bound to, thus removing the possibility of the
2518 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2519 when a second SOCK_STREAM socket binds and accepts to a host/port
2520 that's already been bound by another socket. The optional preferred
2521 port parameter to bind_port() has been removed. Under no
2522 circumstances should tests be hard coding ports!
2523
2524 test_support.find_unused_port() has also been introduced, which will
2525 pass a temporary socket object to bind_port() in order to obtain an
2526 unused port. The temporary socket object is then closed and
2527 deleted, and the port is returned. This method should only be used
2528 for obtaining an unused port in order to pass to an external program
2529 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2530 a parameter to a server-oriented class that doesn't give you direct
2531 access to the underlying socket used.
2532
2533 Finally, test_support.HOST has been introduced, which should be used
2534 for the host argument of any relevant socket calls (i.e. bind and
2535 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002536
2537 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002538 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002539 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2540 test_asynchat and test_socket_ssl.
2541
Georg Brandl3ee81df2008-05-17 18:14:43 +00002542 It is now possible for multiple instances of the regression test
2543 suite to run in parallel without issue.

2810-----------------
2811
Fred Drakea8ee94b2008-03-01 02:45:07 +00002812- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002813 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002814
Georg Brandlad61bc82008-02-23 15:11:18 +00002815- Issue #2067: file.__exit__() now calls subclasses' close() method.
2816
2817- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002818
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002819- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002820 issue 215555 for a discussion.
2821
Eric Smitha73fbe72008-02-23 03:09:44 +00002822- Added the future_builtins module, which contains hex() and oct().
2823 These are the PEP 3127 version of these functions, designed to be
2824 compatible with the hex() and oct() builtins from Python 3.0. They
2825 differ slightly in their output formats from the existing, unchanged
2826 Python 2.6 builtins. The expected usage of the future_builtins
2827 module is:
2828 from future_builtins import hex, oct
2829
Eric Smith7ef40bf2008-02-20 23:34:22 +00002830- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2831 exponents for exponents with absolute value < 100. Follows C99
2832 standard. This is a change on Windows, which would use 3 digits.
2833 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2834 so that any alterations it does to the resulting string will be
2835 available in stringlib/formatter.h (for float.__format__).
2836
Eric Smith5a3c1352008-02-19 13:21:56 +00002837- Implemented PEP 3101, Advanced String Formatting. This adds a new
2838 builtin format(); a format() method for str and unicode; a
2839 __format__() method to object, str, unicode, int, long, float, and
2840 datetime; the class string.Formatter; and the C API
2841 PyObject_Format().
2842
Georg Brandl3ee81df2008-05-17 18:14:43 +00002843- Fixed several potential crashes, all caused by specially crafted
2844 __del__ methods exploiting objects in temporarily inconsistent
2845 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002846
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002847- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002848 prevent a possible crash: an Abstract Base Class would try to access
2849 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002850
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851- Fixed repr() and str() of complex numbers with infinity or nan as
2852 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002853
Georg Brandl3ee81df2008-05-17 18:14:43 +00002854- Clear all free lists during a gc.collect() of the highest generation
2855 in order to allow pymalloc to free more arenas. Python may give back
2856 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002857
Georg Brandl3ee81df2008-05-17 18:14:43 +00002858- Issue #2045: Fix an infinite recursion triggered when printing a
2859 subclass of collections.defaultdict, if its default_factory is set
2860 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002861
Christian Heimesf75dbef2008-02-08 00:11:31 +00002862- Fixed a minor memory leak in dictobject.c. The content of the free
2863 list was not freed on interpreter shutdown.
2864
Georg Brandl5a7eca12010-03-21 19:29:04 +00002865- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002866 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002867
Georg Brandl3ee81df2008-05-17 18:14:43 +00002868- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2869 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002870 to compact the internal free lists of pre-allocted ints and floats.
2871
Georg Brandl3ee81df2008-05-17 18:14:43 +00002872- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2873 calls. Python expected the return type int but the fork familie
2874 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002875
Georg Brandl3ee81df2008-05-17 18:14:43 +00002876- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2877 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002878
Georg Brandl3ee81df2008-05-17 18:14:43 +00002879- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2880 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002881

2886 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002887
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Patch #1473257: generator objects gain a gi_code attribute. This is
2889 the same object as the func_code attribute of the function that
2890 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002891
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892- Issue #1920: "while 0" statements were completely removed by the
2893 compiler, even in the presence of an "else" clause, which is
2894 supposed to be run when the condition is false. Now the compiler
2895 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002896
Guido van Rossumeead05f2008-01-24 18:21:02 +00002897- A few crashers fixed: weakref_in_del.py (issue #1377858);
2898 loosing_dict_ref.py (issue #1303614, test67.py);
2899 borrowed_ref_[34].py (not in tracker).
2900
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002901- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002902 suppressed while an extension is loaded by calling SetErrorMode in
2903 dynload_win.c. The error is still reported properly.
2904
Georg Brandl3ee81df2008-05-17 18:14:43 +00002905- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002906 several extension methods and modules do not work without unicode
2907 support.
2908
Georg Brandl26543b12008-01-21 18:36:51 +00002909- Issue #1882: when compiling code from a string, encoding cookies in the
2910 second line of code were not always recognized correctly.
2911
Georg Brandl14404b62008-01-19 19:27:05 +00002912- Issue #1679: "0x" was taken as a valid integer literal.
2913
Georg Brandl6caad7d2008-01-26 14:19:22 +00002914- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002915 added.
2916
Christian Heimesc94e2b52008-01-14 04:13:37 +00002917- sys.float_info / PyFloat_GetInfo: The floating point information
2918 object was converted from a dict to a specialized structseq object.
2919
Georg Brandl3ee81df2008-05-17 18:14:43 +00002920- Patch #1816: Added sys.flags structseq. It exposes the status of
2921 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002922
Georg Brandl3ee81df2008-05-17 18:14:43 +00002923- Objects/structseq.c: Implemented new structseq representation. The
2924 patch makes structseqs (e.g. the return value of os.stat) more
2925 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002926
Georg Brandl3ee81df2008-05-17 18:14:43 +00002927- Patch #1700288: added a type attribute cache that caches method
2928 accesses, resulting in speedups in heavily object-oriented code.

2936 envvar and sys.dont_write_bytecode attribute. All these can be set
2937 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002938
Georg Brandl3ee81df2008-05-17 18:14:43 +00002939- Improve some exception messages when Windows fails to load an
2940 extension module. Now we get for example '%1 is not a valid Win32
2941 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002942

2954 dictionary size. There is a new opcode, STORE_MAP, for adding
2955 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003000 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3001 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003002
Georg Brandl3ee81df2008-05-17 18:14:43 +00003003- Issue #1686386: Tuple's tp_repr did not take into account the
3004 possibility of having a self-referential tuple, which is possible
3005 from C code. Nor did object's tp_str consider that a type's tp_str
3006 could do something that could lead to an inifinite recursion.
3007 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3008 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Issue #1164: It was possible to trigger deadlock when using the
3011 'print' statement to write to a file since the GIL was not released
3012 as needed. Now PyObject_Print() does the right thing along with
3013 various tp_print implementations of the built-in types and those in
3014 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003024 PyObject_Call() never calling back out to Python code to trigger
3025 recursion depth updates/checks. Required the creation of a static

3051 calls.
3052
Collin Winter62903052007-05-18 23:11:24 +00003053- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054 "except E as target:". This is to provide forwards compatibility
3055 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003062- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003063 setting a plain string, ie don't expand to single letter identifiers.
3064
Raymond Hettinger13936692007-04-11 18:40:58 +00003065- Request #1191699: Slices can now be pickled.

3069 remaining characters.
3070
Georg Brandl5cb76c12007-03-21 09:00:39 +00003071- Patch #1682205: a TypeError while unpacking an iterable is no longer

3075
Guido van Rossum143b5642007-03-23 04:58:42 +00003076- Bug #1683368: The object.__init__() and object.__new__() methods are
3077 now stricter in rejecting excess arguments. The only time when
3078 either allows excess arguments is when it is not overridden and the
3079 other one is. For backwards compatibility, when both are
3080 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003081 warning later). Also, type.__init__() insists on the same signature
3082 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003083
Georg Brandl3ee81df2008-05-17 18:14:43 +00003084- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3085 object to complex using its __complex__() method before falling back
3086 to the __float__() method. Therefore, the functions in the cmath
3087 module now can operate on objects that define a __complex__()
3088 method.

3105
Georg Brandl7b9c5552007-03-12 14:30:05 +00003106- Bug #1678647: write a newline after printing an exception in any
3107 case, even when converting the value to a string failed.
3108
Georg Brandl871f1bc2007-03-12 13:17:36 +00003109- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110 its argument, if it exists. If not, it will work like before. This
3111 allows customizing the output of dir() in the presence of a
3112 __getattr__().

3122 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003123
Georg Brandlaa2321b2007-03-07 00:40:28 +00003124- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003125 makes the filenames the warning module prints much more sensible
3126 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003139- Patch #1674228: when assigning a slice (old-style), check for the
3140 sq_ass_slice instead of the sq_slice slot.
3141
Georg Brandl3ee81df2008-05-17 18:14:43 +00003142- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003677 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00003679

Georg Brandl3ee81df2008-05-17 18:14:43 +00003695- Patch #1530482: add pydoc.render_doc() which returns the

3710
Georg Brandl92a6bae2007-03-13 17:43:32 +00003711- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003712 are set for invalid interpolation sequences that would lead to
3713 errors on reading back those values.

3767
Georg Brandl3ee81df2008-05-17 18:14:43 +00003768- unittest now verifies more of its assumptions. In particular,
3769 TestCase and TestSuite subclasses (not instances) are no longer
3770 accepted in TestSuite.addTest(). This should cause no
3771 incompatibility since it never made sense with ordinary subclasses
3772 -- the failure just occurred later, with a more cumbersome
3773 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004060 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004062 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004161- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004162 time so that opening a database previously created with the DB_DUP
4163 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4164 opens. Specifically: dictionary assignment to a DB object will
4165 replace all values for a given key when the database allows
4166 duplicate values. DB users should use DB.put(k, v) when they want
4167 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004447 periodic threadstate and signal checking in tight loops. By
4448 default, this option is turned-off. It should only be enabled in

Christian Heimes5b970ad2008-02-06 13:33:44 +00004506
Georg Brandl3ee81df2008-05-17 18:14:43 +00004507- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4508 to ``PyTuple_SetItem``, it can be used to populate a brand new

4521
Georg Brandl3ee81df2008-05-17 18:14:43 +00004522- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4523 of w# format code incorrectly truncated the length to an int, even
4524 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4525 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004555- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4556 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004557

Georg Brandl3ee81df2008-05-17 18:14:43 +00004583- Removed the macfs module. It had been deprecated since Python 2.5.
4584 This lead to the deprecation of macostools.touched() as it relied
