1341What's New in Python 2.6.1
1342==========================
1343
1344*Release date: 04-Dec-2008*
1345
1346Core and Builtins
1347-----------------
1348
1349- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1350 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1351 instead of throwing a MemoryError.
1352
1353- Issue #4367: Python would segfault during compiling when the unicodedata
1354 module couldn't be imported and \N escapes were present.
1355
1356- Issue #4348: Some bytearray methods returned that didn't cause any change to
1357 the bytearray, returned the same bytearray instead of a copy.
1358
1359- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1360
1361- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1362
1363- Issue #4048: The parser module now correctly validates relative imports.
1364
1365- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1371- Issue #4209: Enabling unicode_literals and the print_function in the same
1372 __future__ import didn't work.
1373
1374- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1375 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1376 really executed because I cannot move to such directory on win2k)
1377
1378- Issue #4069: When set.remove(element) is used with a set element, the element
1379 is temporarily replaced with an equivalent frozenset. But the eventual
1380 KeyError would always report the empty frozenset([]) as the missing key. Now
1381 it correctly refers to the initial element.
1382

1384 again.

1532
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001533- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1534 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1535 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1536 ``printf`` function, whereas PyString_FromFormat has an independent
1537 implementation and uses "%zd" on all platforms for size_t values.
1538 This makes a difference on win64, where ``printf`` needs "%Id" to display
1539 64bit values.

1560 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1562 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1563 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001699What's New in Python 2.6 beta 3?
1700================================
1701
Barry Warsaw07a4a382008-08-21 01:15:08 +00001702*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001703
1704Core and Builtins
1705-----------------
1706
Guido van Rossumf8402962008-08-20 15:01:50 +00001707- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1708 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1709 extensions do not automatically benefit from the class attribute
1710 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1711 to their tp_flags field if they care. This is a backwards
1712 compatibility feature; in 3.0, all types will use the cache by
1713 default.
1714
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001715- Keyword arguments can now follow starred arguments. (``f(a, *args,
1716 keyword=23)`` is now valid syntax.)
1717
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001718- ctypes function pointers that are COM methods have a boolean True
1719 value again.
1720
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001721- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1722 by denying s# to parse objects that have a releasebuffer procedure,
1723 and introducing s*.
1724
Georg Brandl1e13ea92008-08-11 09:07:59 +00001725- Issue #3537: Fix an assertion failure when an empty but presized dict
1726 object was stored in the freelist.
1727
Mark Dickinsonb6467572008-08-04 21:30:09 +00001728- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1729 ValueError consistently across platforms.
1730
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001731- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1732 (64bit Unix, for example), unichr() would truncate its argument and return
1733 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1734
Neal Norwitze7d8be82008-07-31 17:17:14 +00001735- Apply security patches from Apple.
1736
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001737- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1738 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1739
Antoine Pitrou92f82162008-07-25 22:22:08 +00001740- Issue #1819: function calls with several named parameters are now on
1741 average 35% faster (as measured by pybench).
1742
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001743- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1744 the python debugger steps into a class statement: the free variables (local
1745 variables defined in an outer scope) would be deleted from the outer scope.
1746
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001747- Issue #2620: Overflow checking when allocating or reallocating memory
1748 was not always being done properly in some python types and extension
1749 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1750 all been updated to perform better checks and places in the code that
1751 would previously leak memory on the error path when such an allocation
1752 failed have been fixed.

1755-------
1756
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001757- Issue #3612: Added some missing basic types in ctypes.wintypes.
1758
Benjamin Petersone977ad42008-08-20 01:42:01 +00001759- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1760 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1761
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001762- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1763 version reported by these tools does not necessarily follow the python
1764 version numbering scheme, so the module is less strict when parsing it.
1765
Nick Coghlanf70385a2008-08-18 12:42:46 +00001766- Issue #2235: Added Py3k warnings for types which will become unhashable
1767 under the stricter __hash__ inheritance rules in 3.0. Several types
1768 which did not meet the rules for hash invariants and were already
1769 unhashable in 3.0 have now been explicitly flagged as unhashable in
1770 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1771 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1772
Brett Cannon88f801d2008-08-18 00:46:22 +00001773- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1774 imported into the module but exposed as part of the module's API.
1775
Brett Cannon7b96f072008-08-18 00:41:11 +00001776- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1777
Brett Cannon46225e72008-08-18 00:36:52 +00001778- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001780- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1781
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001782- Issue #3575: Incremental decoder's decode function now takes bytearray
1783 by using 's*' instead of 't#'.
1784
Jesus Cea585ad8a2009-07-02 15:37:21 +00001785- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001786 fails unicode conversion on 2nd parameter. (windows only)
1787
Facundo Batista94f243a2008-08-17 03:38:39 +00001788- Issue 2464. urllib2 now supports a malformation in the URL received
1789 in a redirect.
1790
Brett Cannonabe423e2008-08-16 21:47:07 +00001791- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001792 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001793
Facundo Batistaeb90b782008-08-16 14:44:07 +00001794- Issue #2776: fixed small issue when handling an URL with double slash
1795 after a 302 response in the case of not going through a proxy.
1796
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001797- Issue #2676: in the email package, content-type parsing was hanging on
1798 pathological input because of quadratic or exponential behaviour of a
1799 regular expression.
1800
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001801- Issue #3476: binary buffered reading through the new "io" library is now
1802 thread-safe.
1803
Brett Cannonbf3157b2008-08-14 05:00:03 +00001804- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1805 since mimetools itself is deprecated. Because modules are cached, all
1806 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1807
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001808- Issue #3134: shutil referenced undefined WindowsError symbol.
1809
Robert Schuppenies14646332008-08-10 11:01:53 +00001810- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1811 menu entries were not deleted.
1812
Brett Cannon83e81842008-08-09 23:30:55 +00001813- Copied the implementation of reduce() to _functools.reduce() to have a
1814 version that did not raise a DeprecationWarning under -3.
1815
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001816- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1817 a MemoryError rather than silently stop the iteration.
1818
Guido van Rossum59ce9012008-08-09 14:55:34 +00001819- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1820 to _sre.compile() will now be rejected. This should not affect anybody
1821 since the re.compile() function never generates invalid re-bytecode.
1822
Skip Montanaroa032bf42008-08-08 22:52:51 +00001823- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1824 upon first access it can be automatically initialized from the csv file if
1825 it wasn't initialized during instantiation.
1826
Brett Cannon3aa2a492008-08-06 22:28:09 +00001827- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1828 the reload() built-in has been removed.
1829
Brett Cannon7e30b672008-08-04 21:52:25 +00001830- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001831 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001842 asking for a specific length. This problem only affected files opened
1843 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001844

1869 file name rather than a ZipInfo instance, so files are extracted with
1870 mode 0600 rather than 000 under Unix.
1871
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001872- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1885 interaction with the tp_hash slot (added in 2.6b2) are now documented
1886
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001887- Issue #643841: The language reference now provides more detailed
1888 coverage of the lookup process for special methods. The disclaimers
1889 regarding lack of coverage of new-style classes have also been

1894================================
1895
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001896*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001898Core and Builtins
1899-----------------
1900
Georg Brandl3e483f62008-07-16 22:57:41 +00001901- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1902 its methods now allow for items objects that can be converted to
1903 an integer using operator.index().
1904
Mark Dickinson64b7e502008-07-16 09:40:03 +00001905- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1906 produced a ValueError instead of giving the correct float.
1907
Eric Smitha5fa5a22008-07-16 00:11:49 +00001908- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1909 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1910
Mark Dickinson7103aa42008-07-15 19:08:33 +00001911- Issue #3008: the float type has a new instance method 'float.hex'
1912 and a new class method 'float.fromhex' to convert floating-point
1913 numbers to and from hexadecimal strings, respectively.
1914
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001915- Issue #2235: __hash__ is once again inherited by default. To allow
1916 collections.Hashable to remain meaningful in the presence of the
1917 default hash implementation (object.__hash__), it is now possible
1918 to explicit block inheritance of hash by setting __hash__=None at
1919 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1920 level.
1921
Nick Coghlanb028f502008-07-13 14:52:36 +00001922- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1923 the parent module cannot be found while performing an absolute import.
1924 This means that an incorrectly defined __package__ attribute will
1925 now only prevent relative imports in that module rather than causing
1926 all imports from that module to fail.
1927
Nick Coghlan14ff9942008-07-08 14:21:42 +00001928- Issue #2517: Allow unicode messages in Exceptions again by correctly
1929 bypassing the instance dictionary when looking up __unicode__ on
1930 new-style classes.
1931
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001932- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1933 set to a custom object whose write() method happens to install
1934 another file in sys.stdout.
1935
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001936- Issue #3088: Corrected a race condition in classes derived from
1937 threading.local: the first member set by a thread could be saved in
1938 another thread's dictionary.
1939
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001940- Issue #3004: Minor change to slice.indices(): the start and stop
1941 arguments are now treated identically, making the behaviour easier
1942 to describe and understand. For example, slice(None, -10,
1943 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1944 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1945 10, -1).
1946
Georg Brandl278fc502008-07-19 12:46:12 +00001947- Issue #3219: Calling a function with repeated keyword arguments,
1948 f(a=2, a=23), would not cause a syntax error. This was a regression
1949 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001950
Georg Brandl278fc502008-07-19 12:46:12 +00001951- Issue #2862: Make int and float freelist management consistent with
1952 other freelists. Changes their CompactFreeList apis into
1953 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001954

1956-------
1957
Thomas Heller57adf222008-08-14 19:10:48 +00001958- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1959 api functions without holding the GIL, which could lead to a fatal
1960 error when they failed.
1961
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001962- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001970- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1971 ForkingPickler.register() to resolve conflict with ctypes.
1972
Vinay Sajip51e65192008-07-18 09:01:10 +00001973- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001974
Thomas Heller880f5292008-07-15 19:39:38 +00001975- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1976 a valid dlerror() message.
1977
Thomas Heller2bad6572008-07-15 17:19:50 +00001978- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1979 incomplete structure was created.
1980

1984
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001985- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001986
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001987- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1988 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001989 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001990 content-length. The problem had been corrected in the 2.4 branch, but never
1991 merged into trunk.
1992
Georg Brandle78fbcc2008-07-05 10:13:36 +00001993- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00002003- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002004 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002005
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002006- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2007 handling is now the same as that of other special attributes like __name__).
2008
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002009- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2010 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002461- Issue #1631171: Re-implement the 'warnings' module in C (the
2462 original Python code has been kept as backup). This will allow for
2463 using the 'warning's machinery in such places as the parser where
2464 use of pure Python code is not possible. Both the ``showarning()``
2465 and ``formatwarning()`` gain an optional 'line' argument which is
2466 not called by default for backwards-compatibility reasons. Setting
2467 ``warnings.showwarning()`` to an implementation that lacks support
2468 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002531- Issue #2550: The approach used by client/server code for obtaining
2532 ports to listen on in network-oriented tests has been refined in an
2533 effort to facilitate running multiple instances of the entire
2534 regression test suite in parallel without issue.
2535 test_support.bind_port() has been fixed such that it will always
2536 return a unique port -- which wasn't always the case with the
2537 previous implementation, especially if socket options had been set
2538 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2539 new implementation of bind_port() will actually raise an exception
2540 if it is passed an AF_INET/SOCK_STREAM socket with either the
2541 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2542 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2543 the socket it's been passed. This currently only applies to
2544 Windows. This option prevents any other sockets from binding to the
2545 host/port we've bound to, thus removing the possibility of the
2546 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2547 when a second SOCK_STREAM socket binds and accepts to a host/port
2548 that's already been bound by another socket. The optional preferred
2549 port parameter to bind_port() has been removed. Under no
2550 circumstances should tests be hard coding ports!
2551
2552 test_support.find_unused_port() has also been introduced, which will
2553 pass a temporary socket object to bind_port() in order to obtain an
2554 unused port. The temporary socket object is then closed and
2555 deleted, and the port is returned. This method should only be used
2556 for obtaining an unused port in order to pass to an external program
2557 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2558 a parameter to a server-oriented class that doesn't give you direct
2559 access to the underlying socket used.
2560
2561 Finally, test_support.HOST has been introduced, which should be used
2562 for the host argument of any relevant socket calls (i.e. bind and
2563 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002564
2565 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002566 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002567 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2568 test_asynchat and test_socket_ssl.
2569
Georg Brandl3ee81df2008-05-17 18:14:43 +00002570 It is now possible for multiple instances of the regression test
2571 suite to run in parallel without issue.

2838-----------------
2839
Fred Drakea8ee94b2008-03-01 02:45:07 +00002840- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002841 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002846
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002847- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002848 issue 215555 for a discussion.
2849
Eric Smitha73fbe72008-02-23 03:09:44 +00002850- Added the future_builtins module, which contains hex() and oct().
2851 These are the PEP 3127 version of these functions, designed to be
2852 compatible with the hex() and oct() builtins from Python 3.0. They
2853 differ slightly in their output formats from the existing, unchanged
2854 Python 2.6 builtins. The expected usage of the future_builtins
2855 module is:
2856 from future_builtins import hex, oct
2857
Eric Smith7ef40bf2008-02-20 23:34:22 +00002858- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2859 exponents for exponents with absolute value < 100. Follows C99
2860 standard. This is a change on Windows, which would use 3 digits.
2861 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2862 so that any alterations it does to the resulting string will be
2863 available in stringlib/formatter.h (for float.__format__).
2864
Eric Smith5a3c1352008-02-19 13:21:56 +00002865- Implemented PEP 3101, Advanced String Formatting. This adds a new
2866 builtin format(); a format() method for str and unicode; a
2867 __format__() method to object, str, unicode, int, long, float, and
2868 datetime; the class string.Formatter; and the C API
2869 PyObject_Format().
2870
Georg Brandl3ee81df2008-05-17 18:14:43 +00002871- Fixed several potential crashes, all caused by specially crafted
2872 __del__ methods exploiting objects in temporarily inconsistent
2873 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002874
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002875- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002876 prevent a possible crash: an Abstract Base Class would try to access
2877 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002878

Georg Brandl3ee81df2008-05-17 18:14:43 +00002882- Clear all free lists during a gc.collect() of the highest generation
2883 in order to allow pymalloc to free more arenas. Python may give back
2884 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002885
Georg Brandl3ee81df2008-05-17 18:14:43 +00002886- Issue #2045: Fix an infinite recursion triggered when printing a
2887 subclass of collections.defaultdict, if its default_factory is set
2888 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002889
Christian Heimesf75dbef2008-02-08 00:11:31 +00002890- Fixed a minor memory leak in dictobject.c. The content of the free
2891 list was not freed on interpreter shutdown.
2892
Georg Brandl5a7eca12010-03-21 19:29:04 +00002893- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00002895
Georg Brandl3ee81df2008-05-17 18:14:43 +00002896- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2897 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002898 to compact the internal free lists of pre-allocted ints and floats.
2899
Georg Brandl3ee81df2008-05-17 18:14:43 +00002900- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2901 calls. Python expected the return type int but the fork familie
2902 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002903

2914 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002915
Georg Brandl3ee81df2008-05-17 18:14:43 +00002916- Patch #1473257: generator objects gain a gi_code attribute. This is
2917 the same object as the func_code attribute of the function that
2918 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002919
Georg Brandl3ee81df2008-05-17 18:14:43 +00002920- Issue #1920: "while 0" statements were completely removed by the
2921 compiler, even in the presence of an "else" clause, which is
2922 supposed to be run when the condition is false. Now the compiler
2923 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002924
Guido van Rossumeead05f2008-01-24 18:21:02 +00002925- A few crashers fixed: weakref_in_del.py (issue #1377858);
2926 loosing_dict_ref.py (issue #1303614, test67.py);
2927 borrowed_ref_[34].py (not in tracker).
2928
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002929- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002930 suppressed while an extension is loaded by calling SetErrorMode in

2932
Georg Brandl3ee81df2008-05-17 18:14:43 +00002933- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002934 several extension methods and modules do not work without unicode
2935 support.
2936
Georg Brandl26543b12008-01-21 18:36:51 +00002937- Issue #1882: when compiling code from a string, encoding cookies in the
2938 second line of code were not always recognized correctly.
2939
Georg Brandl14404b62008-01-19 19:27:05 +00002940- Issue #1679: "0x" was taken as a valid integer literal.
2941
Georg Brandl6caad7d2008-01-26 14:19:22 +00002942- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002943 added.
2944
Christian Heimesc94e2b52008-01-14 04:13:37 +00002945- sys.float_info / PyFloat_GetInfo: The floating point information
2946 object was converted from a dict to a specialized structseq object.
2947
Georg Brandl3ee81df2008-05-17 18:14:43 +00002948- Patch #1816: Added sys.flags structseq. It exposes the status of
2949 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002950
Georg Brandl3ee81df2008-05-17 18:14:43 +00002951- Objects/structseq.c: Implemented new structseq representation. The
2952 patch makes structseqs (e.g. the return value of os.stat) more
2953 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002954

Georg Brandl3ee81df2008-05-17 18:14:43 +00002967- Improve some exception messages when Windows fails to load an
2968 extension module. Now we get for example '%1 is not a valid Win32
2969 application' instead of 'error code 193'.

2982 dictionary size. There is a new opcode, STORE_MAP, for adding
2983 entries to the dictionary.

3013 file can now be directly executed by passing their name to the
3014 interpreter. The directory/zipfile is automatically inserted as the
3015 first entry in sys.path.

3026
Georg Brandl5a7eca12010-03-21 19:29:04 +00003027- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003028 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3029 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003030
Georg Brandl3ee81df2008-05-17 18:14:43 +00003031- Issue #1686386: Tuple's tp_repr did not take into account the
3032 possibility of having a self-referential tuple, which is possible
3033 from C code. Nor did object's tp_str consider that a type's tp_str
3034 could do something that could lead to an inifinite recursion.
3035 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3036 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003037
Georg Brandl3ee81df2008-05-17 18:14:43 +00003038- Issue #1164: It was possible to trigger deadlock when using the
3039 'print' statement to write to a file since the GIL was not released
3040 as needed. Now PyObject_Print() does the right thing along with
3041 various tp_print implementations of the built-in types and those in
3042 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00003051- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003052 PyObject_Call() never calling back out to Python code to trigger
3053 recursion depth updates/checks. Required the creation of a static
3054 RuntimeError instance in case normalizing an exception put the
3055 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00003072 __*__ attributes. (Some already existed, e.g., __doc__ and
3073 __name__.)

3079 calls.
3080
Collin Winter62903052007-05-18 23:11:24 +00003081- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003082 "except E as target:". This is to provide forwards compatibility
3083 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003090- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003091 setting a plain string, ie don't expand to single letter identifiers.
3092
Raymond Hettinger13936692007-04-11 18:40:58 +00003093- Request #1191699: Slices can now be pickled.
3094
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003095- Request #1193128: str.translate() now allows a None argument for
3096 translations that only remove characters without re-mapping the
3097 remaining characters.
3098
Georg Brandl5cb76c12007-03-21 09:00:39 +00003099- Patch #1682205: a TypeError while unpacking an iterable is no longer

3103
Guido van Rossum143b5642007-03-23 04:58:42 +00003104- Bug #1683368: The object.__init__() and object.__new__() methods are
3105 now stricter in rejecting excess arguments. The only time when
3106 either allows excess arguments is when it is not overridden and the
3107 other one is. For backwards compatibility, when both are
3108 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003109 warning later). Also, type.__init__() insists on the same signature
3110 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003111
Georg Brandl3ee81df2008-05-17 18:14:43 +00003112- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3113 object to complex using its __complex__() method before falling back
3114 to the __float__() method. Therefore, the functions in the cmath
3115 module now can operate on objects that define a __complex__()
3116 method.

3133
Georg Brandl7b9c5552007-03-12 14:30:05 +00003134- Bug #1678647: write a newline after printing an exception in any
3135 case, even when converting the value to a string failed.
3136
Georg Brandl871f1bc2007-03-12 13:17:36 +00003137- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003138 its argument, if it exists. If not, it will work like before. This
3139 allows customizing the output of dir() in the presence of a
3140 __getattr__().

3149 parthensized forms. This means complex(repr(x)) now works instead of
3150 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003151
Georg Brandlaa2321b2007-03-07 00:40:28 +00003152- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153 makes the filenames the warning module prints much more sensible
3154 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003167- Patch #1674228: when assigning a slice (old-style), check for the
3168 sq_ass_slice instead of the sq_slice slot.
3169
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003705 AttributeError instead of an IOError when the server's response
3706 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003707

Georg Brandl3ee81df2008-05-17 18:14:43 +00003723- Patch #1530482: add pydoc.render_doc() which returns the

3738
Georg Brandl92a6bae2007-03-13 17:43:32 +00003739- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003740 are set for invalid interpolation sequences that would lead to
3741 errors on reading back those values.

3784 returned string up to the first NUL character.

3795
Georg Brandl3ee81df2008-05-17 18:14:43 +00003796- unittest now verifies more of its assumptions. In particular,
3797 TestCase and TestSuite subclasses (not instances) are no longer
3798 accepted in TestSuite.addTest(). This should cause no
3799 incompatibility since it never made sense with ordinary subclasses
3800 -- the failure just occurred later, with a more cumbersome
3801 exception.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004189- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190 time so that opening a database previously created with the DB_DUP
4191 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4192 opens. Specifically: dictionary assignment to a DB object will
4193 replace all values for a given key when the database allows
4194 duplicate values. DB users should use DB.put(k, v) when they want
4195 to store duplicates; not DB[k] = v.

4202 characters with ASCII value less than 32. Also, it correctly quotes
4203 dots only if they occur on a single line, as opposed to the previous
4204 behavior of quoting dots if they are the second character of any
4205 line.

4551 of w# format code incorrectly truncated the length to an int, even
4552 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4553 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004583- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4584 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
