1333What's New in Python 2.6.1
1334==========================
1335
1336*Release date: 04-Dec-2008*
1337
1338Core and Builtins
1339-----------------
1340
1341- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1342 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1343 instead of throwing a MemoryError.
1344
1345- Issue #4367: Python would segfault during compiling when the unicodedata
1346 module couldn't be imported and \N escapes were present.
1347
1348- Issue #4348: Some bytearray methods returned that didn't cause any change to
1349 the bytearray, returned the same bytearray instead of a copy.
1350
1351- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1352
1353- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1354
1355- Issue #4048: The parser module now correctly validates relative imports.
1356
1357- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1358 exec statement.

1360- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1361 method does not return iterators for the 4th and 5th items.
1362
1363- Issue #4209: Enabling unicode_literals and the print_function in the same
1364 __future__ import didn't work.
1365
1366- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1367 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1368 really executed because I cannot move to such directory on win2k)
1369
1370- Issue #4069: When set.remove(element) is used with a set element, the element
1371 is temporarily replaced with an equivalent frozenset. But the eventual
1372 KeyError would always report the empty frozenset([]) as the missing key. Now
1373 it correctly refers to the initial element.
1374
1375- Fixed C99 style comments in several files. Python is now C89 compatible
1376 again.

1524
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001525- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1526 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1527 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1528 ``printf`` function, whereas PyString_FromFormat has an independent
1529 implementation and uses "%zd" on all platforms for size_t values.
1530 This makes a difference on win64, where ``printf`` needs "%Id" to display

1552 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1626 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1627 for catch_warnings() also led to an improvement in the raising of a
1628 DeprecationWarning related to warnings.warn_explicit().

1648-----------------
1649
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001650- Issue #2975: When compiling several extension modules with Visual Studio 2008
1651 from the same python interpreter, some environment variables would grow
1652 without limit.
1653
Benjamin Peterson37346b22008-08-23 20:27:43 +00001654- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001691What's New in Python 2.6 beta 3?
1692================================
1693
Barry Warsaw07a4a382008-08-21 01:15:08 +00001694*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001695
1696Core and Builtins
1697-----------------
1698
Guido van Rossumf8402962008-08-20 15:01:50 +00001699- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1700 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1701 extensions do not automatically benefit from the class attribute
1702 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1703 to their tp_flags field if they care. This is a backwards
1704 compatibility feature; in 3.0, all types will use the cache by
1705 default.
1706
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001707- Keyword arguments can now follow starred arguments. (``f(a, *args,
1708 keyword=23)`` is now valid syntax.)
1709
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001710- ctypes function pointers that are COM methods have a boolean True
1711 value again.
1712
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001713- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1714 by denying s# to parse objects that have a releasebuffer procedure,
1715 and introducing s*.
1716
Georg Brandl1e13ea92008-08-11 09:07:59 +00001717- Issue #3537: Fix an assertion failure when an empty but presized dict
1718 object was stored in the freelist.
1719
Mark Dickinsonb6467572008-08-04 21:30:09 +00001720- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1721 ValueError consistently across platforms.
1722
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001723- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1724 (64bit Unix, for example), unichr() would truncate its argument and return
1725 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1726
Neal Norwitze7d8be82008-07-31 17:17:14 +00001727- Apply security patches from Apple.
1728
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001729- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1730 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1731
Antoine Pitrou92f82162008-07-25 22:22:08 +00001732- Issue #1819: function calls with several named parameters are now on
1733 average 35% faster (as measured by pybench).
1734
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001735- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1736 the python debugger steps into a class statement: the free variables (local
1737 variables defined in an outer scope) would be deleted from the outer scope.
1738
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001739- Issue #2620: Overflow checking when allocating or reallocating memory
1740 was not always being done properly in some python types and extension
1741 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1742 all been updated to perform better checks and places in the code that
1743 would previously leak memory on the error path when such an allocation
1744 failed have been fixed.
1745
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001746Library
1747-------
1748

1750
Benjamin Petersone977ad42008-08-20 01:42:01 +00001751- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1752 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1753
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001754- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1755 version reported by these tools does not necessarily follow the python
1756 version numbering scheme, so the module is less strict when parsing it.
1757
Nick Coghlanf70385a2008-08-18 12:42:46 +00001758- Issue #2235: Added Py3k warnings for types which will become unhashable
1759 under the stricter __hash__ inheritance rules in 3.0. Several types
1760 which did not meet the rules for hash invariants and were already
1761 unhashable in 3.0 have now been explicitly flagged as unhashable in
1762 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1763 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1764
Brett Cannon88f801d2008-08-18 00:46:22 +00001765- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1773
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001774- Issue #3575: Incremental decoder's decode function now takes bytearray
1775 by using 's*' instead of 't#'.
1776
Jesus Cea585ad8a2009-07-02 15:37:21 +00001777- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001778 fails unicode conversion on 2nd parameter. (windows only)
1779
Facundo Batista94f243a2008-08-17 03:38:39 +00001780- Issue 2464. urllib2 now supports a malformation in the URL received
1781 in a redirect.
1782
Brett Cannonabe423e2008-08-16 21:47:07 +00001783- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001784 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001785
Facundo Batistaeb90b782008-08-16 14:44:07 +00001786- Issue #2776: fixed small issue when handling an URL with double slash
1787 after a 302 response in the case of not going through a proxy.
1788
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001789- Issue #2676: in the email package, content-type parsing was hanging on
1790 pathological input because of quadratic or exponential behaviour of a
1791 regular expression.
1792
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001793- Issue #3476: binary buffered reading through the new "io" library is now
1794 thread-safe.
1795
Brett Cannonbf3157b2008-08-14 05:00:03 +00001796- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1797 since mimetools itself is deprecated. Because modules are cached, all
1798 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1799
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001800- Issue #3134: shutil referenced undefined WindowsError symbol.
1801
Robert Schuppenies14646332008-08-10 11:01:53 +00001802- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1803 menu entries were not deleted.
1804
Brett Cannon83e81842008-08-09 23:30:55 +00001805- Copied the implementation of reduce() to _functools.reduce() to have a
1806 version that did not raise a DeprecationWarning under -3.
1807
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001808- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1809 a MemoryError rather than silently stop the iteration.
1810
Guido van Rossum59ce9012008-08-09 14:55:34 +00001811- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1812 to _sre.compile() will now be rejected. This should not affect anybody
1813 since the re.compile() function never generates invalid re-bytecode.
1814
Skip Montanaroa032bf42008-08-08 22:52:51 +00001815- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00001834 asking for a specific length. This problem only affected files opened
1835 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001836

1861 file name rather than a ZipInfo instance, so files are extracted with
1862 mode 0600 rather than 000 under Unix.
1863
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001864- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001879- Issue #643841: The language reference now provides more detailed
1880 coverage of the lookup process for special methods. The disclaimers
1881 regarding lack of coverage of new-style classes have also been
1882 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001885What's New in Python 2.6 beta 2?
1886================================
1887
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001888*Release date: 17-Jul-2008*
1889
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001890Core and Builtins
1891-----------------
1892
Georg Brandl3e483f62008-07-16 22:57:41 +00001893- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1894 its methods now allow for items objects that can be converted to
1895 an integer using operator.index().
1896
Mark Dickinson64b7e502008-07-16 09:40:03 +00001897- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1898 produced a ValueError instead of giving the correct float.
1899
Eric Smitha5fa5a22008-07-16 00:11:49 +00001900- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1901 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1902
Mark Dickinson7103aa42008-07-15 19:08:33 +00001903- Issue #3008: the float type has a new instance method 'float.hex'
1904 and a new class method 'float.fromhex' to convert floating-point
1905 numbers to and from hexadecimal strings, respectively.
1906
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001907- Issue #2235: __hash__ is once again inherited by default. To allow
1908 collections.Hashable to remain meaningful in the presence of the
1909 default hash implementation (object.__hash__), it is now possible
1910 to explicit block inheritance of hash by setting __hash__=None at
1911 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1912 level.
1913
Nick Coghlanb028f502008-07-13 14:52:36 +00001914- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1915 the parent module cannot be found while performing an absolute import.
1916 This means that an incorrectly defined __package__ attribute will
1917 now only prevent relative imports in that module rather than causing
1918 all imports from that module to fail.
1919
Nick Coghlan14ff9942008-07-08 14:21:42 +00001920- Issue #2517: Allow unicode messages in Exceptions again by correctly
1921 bypassing the instance dictionary when looking up __unicode__ on
1922 new-style classes.
1923
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001924- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1925 set to a custom object whose write() method happens to install
1926 another file in sys.stdout.
1927
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001928- Issue #3088: Corrected a race condition in classes derived from
1929 threading.local: the first member set by a thread could be saved in
1930 another thread's dictionary.
1931
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001932- Issue #3004: Minor change to slice.indices(): the start and stop
1933 arguments are now treated identically, making the behaviour easier
1934 to describe and understand. For example, slice(None, -10,
1935 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1936 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1937 10, -1).
1938
Georg Brandl278fc502008-07-19 12:46:12 +00001939- Issue #3219: Calling a function with repeated keyword arguments,
1940 f(a=2, a=23), would not cause a syntax error. This was a regression
1941 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001942
Georg Brandl278fc502008-07-19 12:46:12 +00001943- Issue #2862: Make int and float freelist management consistent with
1944 other freelists. Changes their CompactFreeList apis into
1945 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001946

1948-------
1949
Thomas Heller57adf222008-08-14 19:10:48 +00001950- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1951 api functions without holding the GIL, which could lead to a fatal
1952 error when they failed.
1953
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001954- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001962- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1963 ForkingPickler.register() to resolve conflict with ctypes.
1964
Vinay Sajip51e65192008-07-18 09:01:10 +00001965- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001966
Thomas Heller880f5292008-07-15 19:39:38 +00001967- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1968 a valid dlerror() message.
1969
Thomas Heller2bad6572008-07-15 17:19:50 +00001970- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1971 incomplete structure was created.
1972

1976
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001977- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001978
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001979- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1980 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001981 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001982 content-length. The problem had been corrected in the 2.4 branch, but never
1983 merged into trunk.
1984
Georg Brandle78fbcc2008-07-05 10:13:36 +00001985- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00001993 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001994
Vinay Sajip51e65192008-07-18 09:01:10 +00001995- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001996 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001997
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001998- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1999 handling is now the same as that of other special attributes like __name__).
2000
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002001- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2002 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002453- Issue #1631171: Re-implement the 'warnings' module in C (the
2454 original Python code has been kept as backup). This will allow for
2455 using the 'warning's machinery in such places as the parser where
2456 use of pure Python code is not possible. Both the ``showarning()``
2457 and ``formatwarning()`` gain an optional 'line' argument which is
2458 not called by default for backwards-compatibility reasons. Setting
2459 ``warnings.showwarning()`` to an implementation that lacks support
2460 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002523- Issue #2550: The approach used by client/server code for obtaining
2524 ports to listen on in network-oriented tests has been refined in an
2525 effort to facilitate running multiple instances of the entire
2526 regression test suite in parallel without issue.
2527 test_support.bind_port() has been fixed such that it will always
2528 return a unique port -- which wasn't always the case with the
2529 previous implementation, especially if socket options had been set
2530 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2531 new implementation of bind_port() will actually raise an exception
2532 if it is passed an AF_INET/SOCK_STREAM socket with either the
2533 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2534 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2535 the socket it's been passed. This currently only applies to
2536 Windows. This option prevents any other sockets from binding to the
2537 host/port we've bound to, thus removing the possibility of the
2538 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2539 when a second SOCK_STREAM socket binds and accepts to a host/port
2540 that's already been bound by another socket. The optional preferred
2541 port parameter to bind_port() has been removed. Under no
2542 circumstances should tests be hard coding ports!
2543
2544 test_support.find_unused_port() has also been introduced, which will
2545 pass a temporary socket object to bind_port() in order to obtain an
2546 unused port. The temporary socket object is then closed and
2547 deleted, and the port is returned. This method should only be used
2548 for obtaining an unused port in order to pass to an external program
2549 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2550 a parameter to a server-oriented class that doesn't give you direct
2551 access to the underlying socket used.
2552
2553 Finally, test_support.HOST has been introduced, which should be used
2554 for the host argument of any relevant socket calls (i.e. bind and
2555 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002556
2557 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002558 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002559 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2560 test_asynchat and test_socket_ssl.
2561
Georg Brandl3ee81df2008-05-17 18:14:43 +00002562 It is now possible for multiple instances of the regression test
2563 suite to run in parallel without issue.

Marc-André Lemburga1867752008-03-20 18:08:00 +00002720 platform.machine() and platform.processor() will report this
2721 information as well.

2830-----------------
2831
Fred Drakea8ee94b2008-03-01 02:45:07 +00002832- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002833 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002835- Issue #2067: file.__exit__() now calls subclasses' close() method.
2836
2837- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002838
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002839- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002840 issue 215555 for a discussion.
2841
Eric Smitha73fbe72008-02-23 03:09:44 +00002842- Added the future_builtins module, which contains hex() and oct().
2843 These are the PEP 3127 version of these functions, designed to be
2844 compatible with the hex() and oct() builtins from Python 3.0. They
2845 differ slightly in their output formats from the existing, unchanged
2846 Python 2.6 builtins. The expected usage of the future_builtins
2847 module is:
2848 from future_builtins import hex, oct
2849
Eric Smith7ef40bf2008-02-20 23:34:22 +00002850- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2851 exponents for exponents with absolute value < 100. Follows C99
2852 standard. This is a change on Windows, which would use 3 digits.
2853 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2854 so that any alterations it does to the resulting string will be
2855 available in stringlib/formatter.h (for float.__format__).
2856
Eric Smith5a3c1352008-02-19 13:21:56 +00002857- Implemented PEP 3101, Advanced String Formatting. This adds a new
2858 builtin format(); a format() method for str and unicode; a
2859 __format__() method to object, str, unicode, int, long, float, and
2860 datetime; the class string.Formatter; and the C API
2861 PyObject_Format().
2862
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863- Fixed several potential crashes, all caused by specially crafted
2864 __del__ methods exploiting objects in temporarily inconsistent
2865 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002866
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002867- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002868 prevent a possible crash: an Abstract Base Class would try to access
2869 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002870

Georg Brandl3ee81df2008-05-17 18:14:43 +00002874- Clear all free lists during a gc.collect() of the highest generation
2875 in order to allow pymalloc to free more arenas. Python may give back
2876 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002877
Georg Brandl3ee81df2008-05-17 18:14:43 +00002878- Issue #2045: Fix an infinite recursion triggered when printing a
2879 subclass of collections.defaultdict, if its default_factory is set
2880 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002881
Christian Heimesf75dbef2008-02-08 00:11:31 +00002882- Fixed a minor memory leak in dictobject.c. The content of the free
2883 list was not freed on interpreter shutdown.
2884
Georg Brandl5a7eca12010-03-21 19:29:04 +00002885- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002886 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002887
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2889 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002890 to compact the internal free lists of pre-allocted ints and floats.
2891
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2893 calls. Python expected the return type int but the fork familie
2894 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002895

2906 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002907
Georg Brandl3ee81df2008-05-17 18:14:43 +00002908- Patch #1473257: generator objects gain a gi_code attribute. This is
2909 the same object as the func_code attribute of the function that
2910 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002911
Georg Brandl3ee81df2008-05-17 18:14:43 +00002912- Issue #1920: "while 0" statements were completely removed by the
2913 compiler, even in the presence of an "else" clause, which is
2914 supposed to be run when the condition is false. Now the compiler
2915 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002916
Guido van Rossumeead05f2008-01-24 18:21:02 +00002917- A few crashers fixed: weakref_in_del.py (issue #1377858);
2918 loosing_dict_ref.py (issue #1303614, test67.py);
2919 borrowed_ref_[34].py (not in tracker).
2920
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002921- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002922 suppressed while an extension is loaded by calling SetErrorMode in

2924
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002926 several extension methods and modules do not work without unicode
2927 support.
2928
Georg Brandl26543b12008-01-21 18:36:51 +00002929- Issue #1882: when compiling code from a string, encoding cookies in the
2930 second line of code were not always recognized correctly.
2931
Georg Brandl14404b62008-01-19 19:27:05 +00002932- Issue #1679: "0x" was taken as a valid integer literal.
2933
Georg Brandl6caad7d2008-01-26 14:19:22 +00002934- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002935 added.
2936
Christian Heimesc94e2b52008-01-14 04:13:37 +00002937- sys.float_info / PyFloat_GetInfo: The floating point information
2938 object was converted from a dict to a specialized structseq object.
2939
Georg Brandl3ee81df2008-05-17 18:14:43 +00002940- Patch #1816: Added sys.flags structseq. It exposes the status of
2941 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002942
Georg Brandl3ee81df2008-05-17 18:14:43 +00002943- Objects/structseq.c: Implemented new structseq representation. The
2944 patch makes structseqs (e.g. the return value of os.stat) more
2945 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002946

2954
Georg Brandl3ee81df2008-05-17 18:14:43 +00002955- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2956 envvar and sys.dont_write_bytecode attribute. All these can be set
2957 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002958
Georg Brandl3ee81df2008-05-17 18:14:43 +00002959- Improve some exception messages when Windows fails to load an
2960 extension module. Now we get for example '%1 is not a valid Win32
2961 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002962

Georg Brandl3ee81df2008-05-17 18:14:43 +00002965- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2966 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002967
Christian Heimes0a8143f2007-12-18 23:22:54 +00002968- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002969 and INF. float("nan"), float("inf") and float("-inf") now work on
2970 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002971
Georg Brandl3ee81df2008-05-17 18:14:43 +00002972- Compiler now generates simpler and faster code for dictionary
2973 literals. The oparg for BUILD_MAP now indicates an estimated
2974 dictionary size. There is a new opcode, STORE_MAP, for adding
2975 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002976
Georg Brandl3ee81df2008-05-17 18:14:43 +00002977- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002985- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002986 SystemError.
2987
Nick Coghlanef01d822007-12-03 12:55:17 +00002988- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00003004- Patch #1739468: Directories and zipfiles containing a __main__.py
3005 file can now be directly executed by passing their name to the
3006 interpreter. The directory/zipfile is automatically inserted as the
3007 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003008
Georg Brandl3ee81df2008-05-17 18:14:43 +00003009- Issue #1265: Fix a problem with sys.settrace, if the tracing
3010 function uses a generator expression when at the same time the
3011 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003012
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003013- sets and frozensets now have an isdisjoint() method.
3014
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003015- optimize the performance of builtin.sum().
3016
Neal Norwitz44f326e2007-10-05 05:29:17 +00003017- Fix warnings found by the new version of the Coverity checker.
3018
Georg Brandl5a7eca12010-03-21 19:29:04 +00003019- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003020 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3021 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003022
Georg Brandl3ee81df2008-05-17 18:14:43 +00003023- Issue #1686386: Tuple's tp_repr did not take into account the
3024 possibility of having a self-referential tuple, which is possible
3025 from C code. Nor did object's tp_str consider that a type's tp_str
3026 could do something that could lead to an inifinite recursion.
3027 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3028 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003029
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030- Issue #1164: It was possible to trigger deadlock when using the
3031 'print' statement to write to a file since the GIL was not released
3032 as needed. Now PyObject_Print() does the right thing along with
3033 various tp_print implementations of the built-in types and those in
3034 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003035
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Issue #1147: Exceptions were directly allowing string exceptions in
3037 their throw() method even though string exceptions no longer
3038 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003039
Georg Brandl3ee81df2008-05-17 18:14:43 +00003040- Issue #1096: Prevent a segfault from getting the repr of a very
3041 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003042
Brett Cannon1e534b52007-09-07 04:18:30 +00003043- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003044 PyObject_Call() never calling back out to Python code to trigger
3045 recursion depth updates/checks. Required the creation of a static
3046 RuntimeError instance in case normalizing an exception put the
3047 recursion check value past its limit. Fixes crashers
3048 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003049
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050- Patch #1031213: Decode source line in SyntaxErrors back to its

3054 with %G.
3055
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056- Prevent expandtabs() on string and unicode objects from causing a
3057 segfault when a large width is passed on 32-bit platforms.

Georg Brandla5ea6892007-06-01 11:33:33 +00003062
Neal Norwitz0ac60192007-05-27 04:08:54 +00003063- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003064 __*__ attributes. (Some already existed, e.g., __doc__ and
3065 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003066
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003067- Add -3 option to the interpreter to warn about features that are
3068 deprecated and will be changed/removed in Python 3.0.
3069
Georg Brandl2134e752007-05-21 20:34:16 +00003070- Patch #1686487: you can now pass any mapping after '**' in function
3071 calls.
3072
Collin Winter62903052007-05-18 23:11:24 +00003073- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074 "except E as target:". This is to provide forwards compatibility
3075 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003076
Brett Cannon229cee22007-05-05 01:34:02 +00003077- Deprecate BaseException.message as per PEP 352.
3078
Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003080 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003081
Vinay Sajip8549ce32007-05-06 17:53:37 +00003082- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003083 setting a plain string, ie don't expand to single letter identifiers.
3084
Raymond Hettinger13936692007-04-11 18:40:58 +00003085- Request #1191699: Slices can now be pickled.
3086
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003087- Request #1193128: str.translate() now allows a None argument for
3088 translations that only remove characters without re-mapping the
3089 remaining characters.
3090
Georg Brandl5cb76c12007-03-21 09:00:39 +00003091- Patch #1682205: a TypeError while unpacking an iterable is no longer
3092 masked by a generic one with the message "unpack non-sequence".
3093
Neal Norwitzaa754b72007-03-21 06:39:48 +00003094- Remove unused file Python/fmod.c.
3095
Guido van Rossum143b5642007-03-23 04:58:42 +00003096- Bug #1683368: The object.__init__() and object.__new__() methods are
3097 now stricter in rejecting excess arguments. The only time when
3098 either allows excess arguments is when it is not overridden and the
3099 other one is. For backwards compatibility, when both are
3100 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003101 warning later). Also, type.__init__() insists on the same signature
3102 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003103
Georg Brandl3ee81df2008-05-17 18:14:43 +00003104- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3105 object to complex using its __complex__() method before falling back
3106 to the __float__() method. Therefore, the functions in the cmath
3107 module now can operate on objects that define a __complex__()
3108 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Patch #1623563: allow __class__ assignment for classes with
3111 __slots__. The old and the new class are still required to have the
3112 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003113
Georg Brandl3ee81df2008-05-17 18:14:43 +00003114- Patch #1642547: Fix an error/crash when encountering syntax errors
3115 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003117- Patch #1462488: Python no longer segfaults when
3118 ``object.__reduce_ex__()`` is called with an object that is faking
3119 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003120
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121- Patch #1680015: Don't modify __slots__ tuple if it contains an

3125
Georg Brandl7b9c5552007-03-12 14:30:05 +00003126- Bug #1678647: write a newline after printing an exception in any
3127 case, even when converting the value to a string failed.
3128
Georg Brandl871f1bc2007-03-12 13:17:36 +00003129- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130 its argument, if it exists. If not, it will work like before. This
3131 allows customizing the output of dir() in the presence of a
3132 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003133
Collin Winter276887b2007-03-12 16:11:39 +00003134- Patch #922167: Python no longer segfaults when faced with infinitely
3135 self-recursive reload() calls (as reported by bug #742342).
3136
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- Patch #1675981: remove unreachable code from ``type.__new__()``
3138 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003140- Patch #1491866: change the complex() constructor to allow
3141 parthensized forms. This means complex(repr(x)) now works instead of
3142 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003143
Georg Brandlaa2321b2007-03-07 00:40:28 +00003144- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003145 makes the filenames the warning module prints much more sensible
3146 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003147
Georg Brandl49aafc92007-03-07 00:34:46 +00003148- Variant of patch #697613: don't exit the interpreter on a SystemExit
3149 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150 variable is given, but break into the interactive interpreter just
3151 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00003158
Georg Brandl0fca97a2007-03-05 22:28:08 +00003159- Patch #1674228: when assigning a slice (old-style), check for the
3160 sq_ass_slice instead of the sq_slice slot.
3161
Georg Brandl3ee81df2008-05-17 18:14:43 +00003162- When printing an unraisable error, don't print exceptions. before
3163 the name. This duplicates the behavior whening normally printing
3164 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003697 AttributeError instead of an IOError when the server's response
3698 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003699

Georg Brandl3ee81df2008-05-17 18:14:43 +00003732 are set for invalid interpolation sequences that would lead to
3733 errors on reading back those values.

3789 TestCase and TestSuite subclasses (not instances) are no longer
3790 accepted in TestSuite.addTest(). This should cause no

3792 -- the failure just occurred later, with a more cumbersome
3793 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004182 time so that opening a database previously created with the DB_DUP
4183 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4184 opens. Specifically: dictionary assignment to a DB object will
4185 replace all values for a given key when the database allows
4186 duplicate values. DB users should use DB.put(k, v) when they want
4187 to store duplicates; not DB[k] = v.

4195 dots only if they occur on a single line, as opposed to the previous
4196 behavior of quoting dots if they are the second character of any
4197 line.

4543 of w# format code incorrectly truncated the length to an int, even
4544 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4545 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4576 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
