1319What's New in Python 2.6.1
1320==========================
1321
1322*Release date: 04-Dec-2008*
1323
1324Core and Builtins
1325-----------------
1326
1327- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1328 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1329 instead of throwing a MemoryError.
1330
1331- Issue #4367: Python would segfault during compiling when the unicodedata
1332 module couldn't be imported and \N escapes were present.
1333
1334- Issue #4348: Some bytearray methods returned that didn't cause any change to
1335 the bytearray, returned the same bytearray instead of a copy.
1336
1337- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1338
1339- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1340
1341- Issue #4048: The parser module now correctly validates relative imports.
1342
1343- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1344 exec statement.
1345
1346- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1347 method does not return iterators for the 4th and 5th items.
1348
1349- Issue #4209: Enabling unicode_literals and the print_function in the same
1350 __future__ import didn't work.
1351
1352- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1353 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1354 really executed because I cannot move to such directory on win2k)
1355
1356- Issue #4069: When set.remove(element) is used with a set element, the element
1357 is temporarily replaced with an equivalent frozenset. But the eventual
1358 KeyError would always report the empty frozenset([]) as the missing key. Now
1359 it correctly refers to the initial element.
1360
1361- Fixed C99 style comments in several files. Python is now C89 compatible
1362 again.

1510
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001511- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1512 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1513 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1514 ``printf`` function, whereas PyString_FromFormat has an independent
1515 implementation and uses "%zd" on all platforms for size_t values.
1516 This makes a difference on win64, where ``printf`` needs "%Id" to display
1517 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001519- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitrou0668c622008-08-26 22:42:08 +00001537 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1538 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1540 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1541 type object.

1610
Brett Cannon1eaf0742008-09-02 01:25:16 +00001611- Issue 3602: Moved test.test_support.catch_warning() to
1612 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1613 for catch_warnings() also led to an improvement in the raising of a
1614 DeprecationWarning related to warnings.warn_explicit().
1615
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001616- The deprecation warnings for the old camelCase threading API were removed.

1634-----------------
1635
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001636- Issue #2975: When compiling several extension modules with Visual Studio 2008
1637 from the same python interpreter, some environment variables would grow
1638 without limit.
1639
Benjamin Peterson37346b22008-08-23 20:27:43 +00001640- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1656 wrapper for warnings.catch_warnings() that makes it easier to check
1657 that expected warning messages are being reported.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001677What's New in Python 2.6 beta 3?
1678================================
1679
Barry Warsaw07a4a382008-08-21 01:15:08 +00001680*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001681
1682Core and Builtins
1683-----------------
1684
Guido van Rossumf8402962008-08-20 15:01:50 +00001685- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1686 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1687 extensions do not automatically benefit from the class attribute
1688 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1689 to their tp_flags field if they care. This is a backwards
1690 compatibility feature; in 3.0, all types will use the cache by
1691 default.
1692
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001693- Keyword arguments can now follow starred arguments. (``f(a, *args,
1694 keyword=23)`` is now valid syntax.)
1695
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001696- ctypes function pointers that are COM methods have a boolean True
1697 value again.
1698
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001699- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1700 by denying s# to parse objects that have a releasebuffer procedure,
1701 and introducing s*.
1702
Georg Brandl1e13ea92008-08-11 09:07:59 +00001703- Issue #3537: Fix an assertion failure when an empty but presized dict
1704 object was stored in the freelist.
1705
Mark Dickinsonb6467572008-08-04 21:30:09 +00001706- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1707 ValueError consistently across platforms.
1708
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001709- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1710 (64bit Unix, for example), unichr() would truncate its argument and return
1711 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1712
Neal Norwitze7d8be82008-07-31 17:17:14 +00001713- Apply security patches from Apple.
1714
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001715- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1716 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1717
Antoine Pitrou92f82162008-07-25 22:22:08 +00001718- Issue #1819: function calls with several named parameters are now on
1719 average 35% faster (as measured by pybench).
1720
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001721- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1722 the python debugger steps into a class statement: the free variables (local
1723 variables defined in an outer scope) would be deleted from the outer scope.
1724
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001725- Issue #2620: Overflow checking when allocating or reallocating memory
1726 was not always being done properly in some python types and extension
1727 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1728 all been updated to perform better checks and places in the code that
1729 would previously leak memory on the error path when such an allocation
1730 failed have been fixed.
1731
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001732Library
1733-------
1734

1736
Benjamin Petersone977ad42008-08-20 01:42:01 +00001737- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1738 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1739
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001740- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1741 version reported by these tools does not necessarily follow the python
1742 version numbering scheme, so the module is less strict when parsing it.
1743
Nick Coghlanf70385a2008-08-18 12:42:46 +00001744- Issue #2235: Added Py3k warnings for types which will become unhashable
1745 under the stricter __hash__ inheritance rules in 3.0. Several types
1746 which did not meet the rules for hash invariants and were already
1747 unhashable in 3.0 have now been explicitly flagged as unhashable in
1748 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1749 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1750
Brett Cannon88f801d2008-08-18 00:46:22 +00001751- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1752 imported into the module but exposed as part of the module's API.
1753

1755
Brett Cannon46225e72008-08-18 00:36:52 +00001756- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001758- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1759
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001760- Issue #3575: Incremental decoder's decode function now takes bytearray
1761 by using 's*' instead of 't#'.
1762
Jesus Cea585ad8a2009-07-02 15:37:21 +00001763- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001764 fails unicode conversion on 2nd parameter. (windows only)
1765
Facundo Batista94f243a2008-08-17 03:38:39 +00001766- Issue 2464. urllib2 now supports a malformation in the URL received
1767 in a redirect.
1768
Brett Cannonabe423e2008-08-16 21:47:07 +00001769- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001770 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001771
Facundo Batistaeb90b782008-08-16 14:44:07 +00001772- Issue #2776: fixed small issue when handling an URL with double slash
1773 after a 302 response in the case of not going through a proxy.
1774
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001775- Issue #2676: in the email package, content-type parsing was hanging on
1776 pathological input because of quadratic or exponential behaviour of a
1777 regular expression.
1778
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001779- Issue #3476: binary buffered reading through the new "io" library is now
1780 thread-safe.
1781
Brett Cannonbf3157b2008-08-14 05:00:03 +00001782- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1783 since mimetools itself is deprecated. Because modules are cached, all
1784 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1785
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001786- Issue #3134: shutil referenced undefined WindowsError symbol.
1787
Robert Schuppenies14646332008-08-10 11:01:53 +00001788- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1789 menu entries were not deleted.
1790
Brett Cannon83e81842008-08-09 23:30:55 +00001791- Copied the implementation of reduce() to _functools.reduce() to have a
1792 version that did not raise a DeprecationWarning under -3.
1793
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001794- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1795 a MemoryError rather than silently stop the iteration.
1796
Guido van Rossum59ce9012008-08-09 14:55:34 +00001797- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1798 to _sre.compile() will now be rejected. This should not affect anybody
1799 since the re.compile() function never generates invalid re-bytecode.
1800
Skip Montanaroa032bf42008-08-08 22:52:51 +00001801- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1802 upon first access it can be automatically initialized from the csv file if
1803 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00001805- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1806 the reload() built-in has been removed.
1807
Brett Cannon7e30b672008-08-04 21:52:25 +00001808- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001809 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001820 asking for a specific length. This problem only affected files opened
1821 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001822

1848 mode 0600 rather than 000 under Unix.
1849
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001850- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1851 argument in python 2.5, this broke code that subclassed Popen to include its

Georg Brandl3e483f62008-07-16 22:57:41 +00001879- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1880 its methods now allow for items objects that can be converted to
1881 an integer using operator.index().
1882
Mark Dickinson64b7e502008-07-16 09:40:03 +00001883- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1884 produced a ValueError instead of giving the correct float.
1885
Eric Smitha5fa5a22008-07-16 00:11:49 +00001886- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1887 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1888
Mark Dickinson7103aa42008-07-15 19:08:33 +00001889- Issue #3008: the float type has a new instance method 'float.hex'
1890 and a new class method 'float.fromhex' to convert floating-point
1891 numbers to and from hexadecimal strings, respectively.
1892
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001893- Issue #2235: __hash__ is once again inherited by default. To allow
1894 collections.Hashable to remain meaningful in the presence of the
1895 default hash implementation (object.__hash__), it is now possible
1896 to explicit block inheritance of hash by setting __hash__=None at
1897 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1898 level.
1899
Nick Coghlanb028f502008-07-13 14:52:36 +00001900- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1901 the parent module cannot be found while performing an absolute import.
1902 This means that an incorrectly defined __package__ attribute will
1903 now only prevent relative imports in that module rather than causing
1904 all imports from that module to fail.
1905
Nick Coghlan14ff9942008-07-08 14:21:42 +00001906- Issue #2517: Allow unicode messages in Exceptions again by correctly
1907 bypassing the instance dictionary when looking up __unicode__ on
1908 new-style classes.
1909
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001910- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1911 set to a custom object whose write() method happens to install
1912 another file in sys.stdout.
1913
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001914- Issue #3088: Corrected a race condition in classes derived from
1915 threading.local: the first member set by a thread could be saved in
1916 another thread's dictionary.
1917
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001918- Issue #3004: Minor change to slice.indices(): the start and stop
1919 arguments are now treated identically, making the behaviour easier
1920 to describe and understand. For example, slice(None, -10,
1921 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1922 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1923 10, -1).
1924
Georg Brandl278fc502008-07-19 12:46:12 +00001925- Issue #3219: Calling a function with repeated keyword arguments,
1926 f(a=2, a=23), would not cause a syntax error. This was a regression
1927 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001928
Georg Brandl278fc502008-07-19 12:46:12 +00001929- Issue #2862: Make int and float freelist management consistent with
1930 other freelists. Changes their CompactFreeList apis into
1931 ClearFreeList apis and calls them via gc.collect().

1935
Thomas Heller57adf222008-08-14 19:10:48 +00001936- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1937 api functions without holding the GIL, which could lead to a fatal
1938 error when they failed.
1939
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001940- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1949 ForkingPickler.register() to resolve conflict with ctypes.
1950
Vinay Sajip51e65192008-07-18 09:01:10 +00001951- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001952

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001964
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001965- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1966 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001967 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001968 content-length. The problem had been corrected in the 2.4 branch, but never
1969 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001984- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1985 handling is now the same as that of other special attributes like __name__).
1986
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001987- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002439- Issue #1631171: Re-implement the 'warnings' module in C (the
2440 original Python code has been kept as backup). This will allow for
2441 using the 'warning's machinery in such places as the parser where
2442 use of pure Python code is not possible. Both the ``showarning()``
2443 and ``formatwarning()`` gain an optional 'line' argument which is
2444 not called by default for backwards-compatibility reasons. Setting
2445 ``warnings.showwarning()`` to an implementation that lacks support
2446 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002509- Issue #2550: The approach used by client/server code for obtaining
2510 ports to listen on in network-oriented tests has been refined in an
2511 effort to facilitate running multiple instances of the entire
2512 regression test suite in parallel without issue.
2513 test_support.bind_port() has been fixed such that it will always
2514 return a unique port -- which wasn't always the case with the
2515 previous implementation, especially if socket options had been set
2516 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2517 new implementation of bind_port() will actually raise an exception
2518 if it is passed an AF_INET/SOCK_STREAM socket with either the
2519 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2520 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2521 the socket it's been passed. This currently only applies to
2522 Windows. This option prevents any other sockets from binding to the
2523 host/port we've bound to, thus removing the possibility of the
2524 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2525 when a second SOCK_STREAM socket binds and accepts to a host/port
2526 that's already been bound by another socket. The optional preferred
2527 port parameter to bind_port() has been removed. Under no
2528 circumstances should tests be hard coding ports!
2529
2530 test_support.find_unused_port() has also been introduced, which will
2531 pass a temporary socket object to bind_port() in order to obtain an
2532 unused port. The temporary socket object is then closed and
2533 deleted, and the port is returned. This method should only be used
2534 for obtaining an unused port in order to pass to an external program
2535 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2536 a parameter to a server-oriented class that doesn't give you direct
2537 access to the underlying socket used.
2538
2539 Finally, test_support.HOST has been introduced, which should be used
2540 for the host argument of any relevant socket calls (i.e. bind and
2541 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002542
2543 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002544 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002545 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2546 test_asynchat and test_socket_ssl.
2547
Georg Brandl3ee81df2008-05-17 18:14:43 +00002548 It is now possible for multiple instances of the regression test
2549 suite to run in parallel without issue.

2705 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002706 platform.machine() and platform.processor() will report this
2707 information as well.

2816-----------------
2817
Fred Drakea8ee94b2008-03-01 02:45:07 +00002818- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002819 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002821- Issue #2067: file.__exit__() now calls subclasses' close() method.
2822
2823- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002824
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002825- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002826 issue 215555 for a discussion.
2827
Eric Smitha73fbe72008-02-23 03:09:44 +00002828- Added the future_builtins module, which contains hex() and oct().
2829 These are the PEP 3127 version of these functions, designed to be
2830 compatible with the hex() and oct() builtins from Python 3.0. They
2831 differ slightly in their output formats from the existing, unchanged
2832 Python 2.6 builtins. The expected usage of the future_builtins
2833 module is:
2834 from future_builtins import hex, oct
2835
Eric Smith7ef40bf2008-02-20 23:34:22 +00002836- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2837 exponents for exponents with absolute value < 100. Follows C99
2838 standard. This is a change on Windows, which would use 3 digits.
2839 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2840 so that any alterations it does to the resulting string will be
2841 available in stringlib/formatter.h (for float.__format__).
2842
Eric Smith5a3c1352008-02-19 13:21:56 +00002843- Implemented PEP 3101, Advanced String Formatting. This adds a new
2844 builtin format(); a format() method for str and unicode; a
2845 __format__() method to object, str, unicode, int, long, float, and
2846 datetime; the class string.Formatter; and the C API
2847 PyObject_Format().
2848
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- Fixed several potential crashes, all caused by specially crafted
2850 __del__ methods exploiting objects in temporarily inconsistent
2851 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002852
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002853- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002854 prevent a possible crash: an Abstract Base Class would try to access
2855 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002856
Georg Brandl3ee81df2008-05-17 18:14:43 +00002857- Fixed repr() and str() of complex numbers with infinity or nan as
2858 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002859
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860- Clear all free lists during a gc.collect() of the highest generation
2861 in order to allow pymalloc to free more arenas. Python may give back
2862 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002863
Georg Brandl3ee81df2008-05-17 18:14:43 +00002864- Issue #2045: Fix an infinite recursion triggered when printing a
2865 subclass of collections.defaultdict, if its default_factory is set
2866 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002867
Christian Heimesf75dbef2008-02-08 00:11:31 +00002868- Fixed a minor memory leak in dictobject.c. The content of the free
2869 list was not freed on interpreter shutdown.
2870
Georg Brandl5a7eca12010-03-21 19:29:04 +00002871- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002872 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002873
Georg Brandl3ee81df2008-05-17 18:14:43 +00002874- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2875 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002876 to compact the internal free lists of pre-allocted ints and floats.
2877
Georg Brandl3ee81df2008-05-17 18:14:43 +00002878- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2879 calls. Python expected the return type int but the fork familie
2880 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002881
Georg Brandl3ee81df2008-05-17 18:14:43 +00002882- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2883 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002884
Georg Brandl3ee81df2008-05-17 18:14:43 +00002885- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2886 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002887
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2889 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002891- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2892 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002893
Georg Brandl3ee81df2008-05-17 18:14:43 +00002894- Patch #1473257: generator objects gain a gi_code attribute. This is
2895 the same object as the func_code attribute of the function that
2896 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002897
Georg Brandl3ee81df2008-05-17 18:14:43 +00002898- Issue #1920: "while 0" statements were completely removed by the
2899 compiler, even in the presence of an "else" clause, which is
2900 supposed to be run when the condition is false. Now the compiler
2901 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002902
Guido van Rossumeead05f2008-01-24 18:21:02 +00002903- A few crashers fixed: weakref_in_del.py (issue #1377858);
2904 loosing_dict_ref.py (issue #1303614, test67.py);
2905 borrowed_ref_[34].py (not in tracker).
2906
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002907- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002908 suppressed while an extension is loaded by calling SetErrorMode in
2909 dynload_win.c. The error is still reported properly.
2910
Georg Brandl3ee81df2008-05-17 18:14:43 +00002911- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002912 several extension methods and modules do not work without unicode
2913 support.
2914
Georg Brandl26543b12008-01-21 18:36:51 +00002915- Issue #1882: when compiling code from a string, encoding cookies in the
2916 second line of code were not always recognized correctly.
2917
Georg Brandl14404b62008-01-19 19:27:05 +00002918- Issue #1679: "0x" was taken as a valid integer literal.
2919
Georg Brandl6caad7d2008-01-26 14:19:22 +00002920- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002921 added.
2922
Christian Heimesc94e2b52008-01-14 04:13:37 +00002923- sys.float_info / PyFloat_GetInfo: The floating point information
2924 object was converted from a dict to a specialized structseq object.
2925
Georg Brandl3ee81df2008-05-17 18:14:43 +00002926- Patch #1816: Added sys.flags structseq. It exposes the status of
2927 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002928
Georg Brandl3ee81df2008-05-17 18:14:43 +00002929- Objects/structseq.c: Implemented new structseq representation. The
2930 patch makes structseqs (e.g. the return value of os.stat) more
2931 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002932
Georg Brandl3ee81df2008-05-17 18:14:43 +00002933- Patch #1700288: added a type attribute cache that caches method
2934 accesses, resulting in speedups in heavily object-oriented code.

2942 envvar and sys.dont_write_bytecode attribute. All these can be set
2943 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002944
Georg Brandl3ee81df2008-05-17 18:14:43 +00002945- Improve some exception messages when Windows fails to load an
2946 extension module. Now we get for example '%1 is not a valid Win32
2947 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002954- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002955 and INF. float("nan"), float("inf") and float("-inf") now work on
2956 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002958- Compiler now generates simpler and faster code for dictionary
2959 literals. The oparg for BUILD_MAP now indicates an estimated
2960 dictionary size. There is a new opcode, STORE_MAP, for adding
2961 entries to the dictionary.

2991 file can now be directly executed by passing their name to the
2992 interpreter. The directory/zipfile is automatically inserted as the
2993 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Issue #1265: Fix a problem with sys.settrace, if the tracing
2996 function uses a generator expression when at the same time the
2997 executed code is closing a paused generator.

3004
Georg Brandl5a7eca12010-03-21 19:29:04 +00003005- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003006 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3007 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003008
Georg Brandl3ee81df2008-05-17 18:14:43 +00003009- Issue #1686386: Tuple's tp_repr did not take into account the
3010 possibility of having a self-referential tuple, which is possible
3011 from C code. Nor did object's tp_str consider that a type's tp_str
3012 could do something that could lead to an inifinite recursion.
3013 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3014 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003015
Georg Brandl3ee81df2008-05-17 18:14:43 +00003016- Issue #1164: It was possible to trigger deadlock when using the
3017 'print' statement to write to a file since the GIL was not released
3018 as needed. Now PyObject_Print() does the right thing along with
3019 various tp_print implementations of the built-in types and those in
3020 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003021
Georg Brandl3ee81df2008-05-17 18:14:43 +00003022- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00003028
Brett Cannon1e534b52007-09-07 04:18:30 +00003029- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030 PyObject_Call() never calling back out to Python code to trigger
3031 recursion depth updates/checks. Required the creation of a static
3032 RuntimeError instance in case normalizing an exception put the
3033 recursion check value past its limit. Fixes crashers
3034 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003035

Neal Norwitz0ac60192007-05-27 04:08:54 +00003049- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050 __*__ attributes. (Some already existed, e.g., __doc__ and
3051 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003052
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003053- Add -3 option to the interpreter to warn about features that are
3054 deprecated and will be changed/removed in Python 3.0.
3055
Georg Brandl2134e752007-05-21 20:34:16 +00003056- Patch #1686487: you can now pass any mapping after '**' in function
3057 calls.
3058
Collin Winter62903052007-05-18 23:11:24 +00003059- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003060 "except E as target:". This is to provide forwards compatibility
3061 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003062
Brett Cannon229cee22007-05-05 01:34:02 +00003063- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003065- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003066 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003067
Vinay Sajip8549ce32007-05-06 17:53:37 +00003068- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003069 setting a plain string, ie don't expand to single letter identifiers.
3070
Raymond Hettinger13936692007-04-11 18:40:58 +00003071- Request #1191699: Slices can now be pickled.
3072
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003073- Request #1193128: str.translate() now allows a None argument for
3074 translations that only remove characters without re-mapping the
3075 remaining characters.
3076
Georg Brandl5cb76c12007-03-21 09:00:39 +00003077- Patch #1682205: a TypeError while unpacking an iterable is no longer
3078 masked by a generic one with the message "unpack non-sequence".
3079

3081
Guido van Rossum143b5642007-03-23 04:58:42 +00003082- Bug #1683368: The object.__init__() and object.__new__() methods are
3083 now stricter in rejecting excess arguments. The only time when
3084 either allows excess arguments is when it is not overridden and the
3085 other one is. For backwards compatibility, when both are
3086 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003087 warning later). Also, type.__init__() insists on the same signature
3088 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003089
Georg Brandl3ee81df2008-05-17 18:14:43 +00003090- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3091 object to complex using its __complex__() method before falling back
3092 to the __float__() method. Therefore, the functions in the cmath
3093 module now can operate on objects that define a __complex__()
3094 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003095
Georg Brandl3ee81df2008-05-17 18:14:43 +00003096- Patch #1623563: allow __class__ assignment for classes with
3097 __slots__. The old and the new class are still required to have the
3098 same slot names.

3104 ``object.__reduce_ex__()`` is called with an object that is faking
3105 its type.

3111
Georg Brandl7b9c5552007-03-12 14:30:05 +00003112- Bug #1678647: write a newline after printing an exception in any
3113 case, even when converting the value to a string failed.
3114
Georg Brandl871f1bc2007-03-12 13:17:36 +00003115- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116 its argument, if it exists. If not, it will work like before. This
3117 allows customizing the output of dir() in the presence of a
3118 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003119
Collin Winter276887b2007-03-12 16:11:39 +00003120- Patch #922167: Python no longer segfaults when faced with infinitely
3121 self-recursive reload() calls (as reported by bug #742342).
3122
Georg Brandl3ee81df2008-05-17 18:14:43 +00003123- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Patch #1491866: change the complex() constructor to allow
3127 parthensized forms. This means complex(repr(x)) now works instead of
3128 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003129
Georg Brandlaa2321b2007-03-07 00:40:28 +00003130- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003131 makes the filenames the warning module prints much more sensible
3132 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003133

Georg Brandl0fca97a2007-03-05 22:28:08 +00003145- Patch #1674228: when assigning a slice (old-style), check for the
3146 sq_ass_slice instead of the sq_slice slot.
3147
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- When printing an unraisable error, don't print exceptions. before
3149 the name. This duplicates the behavior whening normally printing
3150 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003701- Patch #1530482: add pydoc.render_doc() which returns the

3716
Georg Brandl92a6bae2007-03-13 17:43:32 +00003717- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003718 are set for invalid interpolation sequences that would lead to
3719 errors on reading back those values.

3775 TestCase and TestSuite subclasses (not instances) are no longer
3776 accepted in TestSuite.addTest(). This should cause no
3777 incompatibility since it never made sense with ordinary subclasses
3778 -- the failure just occurred later, with a more cumbersome
3779 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004066 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004167- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004168 time so that opening a database previously created with the DB_DUP
4169 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4170 opens. Specifically: dictionary assignment to a DB object will
4171 replace all values for a given key when the database allows
4172 duplicate values. DB users should use DB.put(k, v) when they want
4173 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004452- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004453 periodic threadstate and signal checking in tight loops. By
4454 default, this option is turned-off. It should only be enabled in

Georg Brandl3ee81df2008-05-17 18:14:43 +00004513- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4514 to ``PyTuple_SetItem``, it can be used to populate a brand new

4527
Georg Brandl3ee81df2008-05-17 18:14:43 +00004528- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4529 of w# format code incorrectly truncated the length to an int, even
4530 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4531 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004532

Georg Brandl3ee81df2008-05-17 18:14:43 +00004561- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4562 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004563

Georg Brandl3ee81df2008-05-17 18:14:43 +00004589- Removed the macfs module. It had been deprecated since Python 2.5.
4590 This lead to the deprecation of macostools.touched() as it relied
