1326==========================
1327
1328*Release date: 04-Dec-2008*
1329
1330Core and Builtins
1331-----------------
1332
1333- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1334 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1335 instead of throwing a MemoryError.
1336
1337- Issue #4367: Python would segfault during compiling when the unicodedata
1338 module couldn't be imported and \N escapes were present.
1339
1340- Issue #4348: Some bytearray methods returned that didn't cause any change to
1341 the bytearray, returned the same bytearray instead of a copy.
1342
1343- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1344
1345- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1346
1347- Issue #4048: The parser module now correctly validates relative imports.
1348
1349- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1350 exec statement.

1353 method does not return iterators for the 4th and 5th items.
1354
1355- Issue #4209: Enabling unicode_literals and the print_function in the same
1356 __future__ import didn't work.
1357
1358- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1359 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1360 really executed because I cannot move to such directory on win2k)
1361
1362- Issue #4069: When set.remove(element) is used with a set element, the element
1363 is temporarily replaced with an equivalent frozenset. But the eventual
1364 KeyError would always report the empty frozenset([]) as the missing key. Now
1365 it correctly refers to the initial element.
1366
1367- Fixed C99 style comments in several files. Python is now C89 compatible
1368 again.

1516
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001517- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1518 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1519 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1520 ``printf`` function, whereas PyString_FromFormat has an independent
1521 implementation and uses "%zd" on all platforms for size_t values.
1522 This makes a difference on win64, where ``printf`` needs "%Id" to display
1523 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001543 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1544 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1546 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1547 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00001617- Issue 3602: Moved test.test_support.catch_warning() to
1618 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1619 for catch_warnings() also led to an improvement in the raising of a
1620 DeprecationWarning related to warnings.warn_explicit().
1621
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001622- The deprecation warnings for the old camelCase threading API were removed.

Benjamin Peterson37346b22008-08-23 20:27:43 +00001639Extension Modules
1640-----------------
1641
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001642- Issue #2975: When compiling several extension modules with Visual Studio 2008
1643 from the same python interpreter, some environment variables would grow
1644 without limit.
1645
Benjamin Peterson37346b22008-08-23 20:27:43 +00001646- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001683What's New in Python 2.6 beta 3?
1684================================
1685
Barry Warsaw07a4a382008-08-21 01:15:08 +00001686*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001687
1688Core and Builtins
1689-----------------
1690
Guido van Rossumf8402962008-08-20 15:01:50 +00001691- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1692 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1693 extensions do not automatically benefit from the class attribute
1694 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1695 to their tp_flags field if they care. This is a backwards
1696 compatibility feature; in 3.0, all types will use the cache by
1697 default.
1698
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001699- Keyword arguments can now follow starred arguments. (``f(a, *args,
1700 keyword=23)`` is now valid syntax.)
1701
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001702- ctypes function pointers that are COM methods have a boolean True
1703 value again.
1704
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001705- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1706 by denying s# to parse objects that have a releasebuffer procedure,
1707 and introducing s*.
1708
Georg Brandl1e13ea92008-08-11 09:07:59 +00001709- Issue #3537: Fix an assertion failure when an empty but presized dict
1710 object was stored in the freelist.
1711
Mark Dickinsonb6467572008-08-04 21:30:09 +00001712- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1713 ValueError consistently across platforms.
1714
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001715- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1716 (64bit Unix, for example), unichr() would truncate its argument and return
1717 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1718
Neal Norwitze7d8be82008-07-31 17:17:14 +00001719- Apply security patches from Apple.
1720
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001721- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1722 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1723
Antoine Pitrou92f82162008-07-25 22:22:08 +00001724- Issue #1819: function calls with several named parameters are now on
1725 average 35% faster (as measured by pybench).
1726
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001727- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1728 the python debugger steps into a class statement: the free variables (local
1729 variables defined in an outer scope) would be deleted from the outer scope.
1730
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001731- Issue #2620: Overflow checking when allocating or reallocating memory
1732 was not always being done properly in some python types and extension
1733 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1734 all been updated to perform better checks and places in the code that
1735 would previously leak memory on the error path when such an allocation
1736 failed have been fixed.
1737
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001738Library
1739-------
1740
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001741- Issue #3612: Added some missing basic types in ctypes.wintypes.
1742
Benjamin Petersone977ad42008-08-20 01:42:01 +00001743- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1744 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1745
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001746- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1747 version reported by these tools does not necessarily follow the python
1748 version numbering scheme, so the module is less strict when parsing it.
1749
Nick Coghlanf70385a2008-08-18 12:42:46 +00001750- Issue #2235: Added Py3k warnings for types which will become unhashable
1751 under the stricter __hash__ inheritance rules in 3.0. Several types
1752 which did not meet the rules for hash invariants and were already
1753 unhashable in 3.0 have now been explicitly flagged as unhashable in
1754 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1755 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1756
Brett Cannon88f801d2008-08-18 00:46:22 +00001757- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1758 imported into the module but exposed as part of the module's API.
1759
Brett Cannon7b96f072008-08-18 00:41:11 +00001760- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1761
Brett Cannon46225e72008-08-18 00:36:52 +00001762- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001764- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1765
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001766- Issue #3575: Incremental decoder's decode function now takes bytearray
1767 by using 's*' instead of 't#'.
1768
Jesus Cea585ad8a2009-07-02 15:37:21 +00001769- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001770 fails unicode conversion on 2nd parameter. (windows only)
1771
Facundo Batista94f243a2008-08-17 03:38:39 +00001772- Issue 2464. urllib2 now supports a malformation in the URL received
1773 in a redirect.
1774
Brett Cannonabe423e2008-08-16 21:47:07 +00001775- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001776 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001777
Facundo Batistaeb90b782008-08-16 14:44:07 +00001778- Issue #2776: fixed small issue when handling an URL with double slash
1779 after a 302 response in the case of not going through a proxy.
1780
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001781- Issue #2676: in the email package, content-type parsing was hanging on
1782 pathological input because of quadratic or exponential behaviour of a
1783 regular expression.
1784
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001785- Issue #3476: binary buffered reading through the new "io" library is now
1786 thread-safe.
1787
Brett Cannonbf3157b2008-08-14 05:00:03 +00001788- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1789 since mimetools itself is deprecated. Because modules are cached, all
1790 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1791
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001792- Issue #3134: shutil referenced undefined WindowsError symbol.
1793
Robert Schuppenies14646332008-08-10 11:01:53 +00001794- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1795 menu entries were not deleted.
1796
Brett Cannon83e81842008-08-09 23:30:55 +00001797- Copied the implementation of reduce() to _functools.reduce() to have a
1798 version that did not raise a DeprecationWarning under -3.
1799
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001800- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1801 a MemoryError rather than silently stop the iteration.
1802
Guido van Rossum59ce9012008-08-09 14:55:34 +00001803- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1804 to _sre.compile() will now be rejected. This should not affect anybody
1805 since the re.compile() function never generates invalid re-bytecode.
1806
Skip Montanaroa032bf42008-08-08 22:52:51 +00001807- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00001826 asking for a specific length. This problem only affected files opened
1827 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001828

1853 file name rather than a ZipInfo instance, so files are extracted with
1854 mode 0600 rather than 000 under Unix.
1855
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001856- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1857 argument in python 2.5, this broke code that subclassed Popen to include its

1878================================
1879
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001880*Release date: 17-Jul-2008*
1881
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001882Core and Builtins
1883-----------------
1884
Georg Brandl3e483f62008-07-16 22:57:41 +00001885- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1886 its methods now allow for items objects that can be converted to
1887 an integer using operator.index().
1888
Mark Dickinson64b7e502008-07-16 09:40:03 +00001889- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1890 produced a ValueError instead of giving the correct float.
1891
Eric Smitha5fa5a22008-07-16 00:11:49 +00001892- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1893 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1894
Mark Dickinson7103aa42008-07-15 19:08:33 +00001895- Issue #3008: the float type has a new instance method 'float.hex'
1896 and a new class method 'float.fromhex' to convert floating-point
1897 numbers to and from hexadecimal strings, respectively.
1898
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001899- Issue #2235: __hash__ is once again inherited by default. To allow
1900 collections.Hashable to remain meaningful in the presence of the
1901 default hash implementation (object.__hash__), it is now possible
1902 to explicit block inheritance of hash by setting __hash__=None at
1903 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1904 level.
1905
Nick Coghlanb028f502008-07-13 14:52:36 +00001906- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1907 the parent module cannot be found while performing an absolute import.
1908 This means that an incorrectly defined __package__ attribute will
1909 now only prevent relative imports in that module rather than causing
1910 all imports from that module to fail.
1911
Nick Coghlan14ff9942008-07-08 14:21:42 +00001912- Issue #2517: Allow unicode messages in Exceptions again by correctly
1913 bypassing the instance dictionary when looking up __unicode__ on
1914 new-style classes.
1915
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001916- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1917 set to a custom object whose write() method happens to install
1918 another file in sys.stdout.
1919
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001920- Issue #3088: Corrected a race condition in classes derived from
1921 threading.local: the first member set by a thread could be saved in
1922 another thread's dictionary.
1923
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001924- Issue #3004: Minor change to slice.indices(): the start and stop
1925 arguments are now treated identically, making the behaviour easier
1926 to describe and understand. For example, slice(None, -10,
1927 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1928 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1929 10, -1).
1930
Georg Brandl278fc502008-07-19 12:46:12 +00001931- Issue #3219: Calling a function with repeated keyword arguments,
1932 f(a=2, a=23), would not cause a syntax error. This was a regression
1933 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001934
Georg Brandl278fc502008-07-19 12:46:12 +00001935- Issue #2862: Make int and float freelist management consistent with
1936 other freelists. Changes their CompactFreeList apis into
1937 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001938
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001939Library
1940-------
1941
Thomas Heller57adf222008-08-14 19:10:48 +00001942- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1943 api functions without holding the GIL, which could lead to a fatal
1944 error when they failed.
1945
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001946- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
1947

Jesse Noller13e9d582008-07-16 14:32:36 +00001954- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1955 ForkingPickler.register() to resolve conflict with ctypes.
1956
Vinay Sajip51e65192008-07-18 09:01:10 +00001957- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001958
Thomas Heller880f5292008-07-15 19:39:38 +00001959- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1960 a valid dlerror() message.
1961
Thomas Heller2bad6572008-07-15 17:19:50 +00001962- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1963 incomplete structure was created.
1964

1968
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001969- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001970
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001971- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1972 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001973 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001974 content-length. The problem had been corrected in the 2.4 branch, but never
1975 merged into trunk.
1976
Georg Brandle78fbcc2008-07-05 10:13:36 +00001977- Issue #2663: add filtering capability to shutil.copytree().

1983- Issue #1746: Correct handling of zipfile archive comments (previously
1984 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001985 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001986
Vinay Sajip51e65192008-07-18 09:01:10 +00001987- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001988 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001989
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001990- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1991 handling is now the same as that of other special attributes like __name__).
1992
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001993- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002445- Issue #1631171: Re-implement the 'warnings' module in C (the
2446 original Python code has been kept as backup). This will allow for
2447 using the 'warning's machinery in such places as the parser where
2448 use of pure Python code is not possible. Both the ``showarning()``
2449 and ``formatwarning()`` gain an optional 'line' argument which is
2450 not called by default for backwards-compatibility reasons. Setting
2451 ``warnings.showwarning()`` to an implementation that lacks support
2452 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002515- Issue #2550: The approach used by client/server code for obtaining
2516 ports to listen on in network-oriented tests has been refined in an
2517 effort to facilitate running multiple instances of the entire
2518 regression test suite in parallel without issue.
2519 test_support.bind_port() has been fixed such that it will always
2520 return a unique port -- which wasn't always the case with the
2521 previous implementation, especially if socket options had been set
2522 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2523 new implementation of bind_port() will actually raise an exception
2524 if it is passed an AF_INET/SOCK_STREAM socket with either the
2525 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2526 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2527 the socket it's been passed. This currently only applies to
2528 Windows. This option prevents any other sockets from binding to the
2529 host/port we've bound to, thus removing the possibility of the
2530 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2531 when a second SOCK_STREAM socket binds and accepts to a host/port
2532 that's already been bound by another socket. The optional preferred
2533 port parameter to bind_port() has been removed. Under no
2534 circumstances should tests be hard coding ports!
2535
2536 test_support.find_unused_port() has also been introduced, which will
2537 pass a temporary socket object to bind_port() in order to obtain an
2538 unused port. The temporary socket object is then closed and
2539 deleted, and the port is returned. This method should only be used
2540 for obtaining an unused port in order to pass to an external program
2541 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2542 a parameter to a server-oriented class that doesn't give you direct
2543 access to the underlying socket used.
2544
2545 Finally, test_support.HOST has been introduced, which should be used
2546 for the host argument of any relevant socket calls (i.e. bind and
2547 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002548
2549 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002551 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2552 test_asynchat and test_socket_ssl.
2553
Georg Brandl3ee81df2008-05-17 18:14:43 +00002554 It is now possible for multiple instances of the regression test
2555 suite to run in parallel without issue.

2711 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002712 platform.machine() and platform.processor() will report this
2713 information as well.

2822-----------------
2823
Fred Drakea8ee94b2008-03-01 02:45:07 +00002824- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002825 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002826
Georg Brandlad61bc82008-02-23 15:11:18 +00002827- Issue #2067: file.__exit__() now calls subclasses' close() method.
2828
2829- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002830
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002831- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002832 issue 215555 for a discussion.
2833
Eric Smitha73fbe72008-02-23 03:09:44 +00002834- Added the future_builtins module, which contains hex() and oct().
2835 These are the PEP 3127 version of these functions, designed to be
2836 compatible with the hex() and oct() builtins from Python 3.0. They
2837 differ slightly in their output formats from the existing, unchanged
2838 Python 2.6 builtins. The expected usage of the future_builtins
2839 module is:
2840 from future_builtins import hex, oct
2841
Eric Smith7ef40bf2008-02-20 23:34:22 +00002842- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2843 exponents for exponents with absolute value < 100. Follows C99
2844 standard. This is a change on Windows, which would use 3 digits.
2845 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2846 so that any alterations it does to the resulting string will be
2847 available in stringlib/formatter.h (for float.__format__).
2848
Eric Smith5a3c1352008-02-19 13:21:56 +00002849- Implemented PEP 3101, Advanced String Formatting. This adds a new
2850 builtin format(); a format() method for str and unicode; a
2851 __format__() method to object, str, unicode, int, long, float, and
2852 datetime; the class string.Formatter; and the C API
2853 PyObject_Format().
2854
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855- Fixed several potential crashes, all caused by specially crafted
2856 __del__ methods exploiting objects in temporarily inconsistent
2857 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002858
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002859- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860 prevent a possible crash: an Abstract Base Class would try to access
2861 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002862

2864 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002865
Georg Brandl3ee81df2008-05-17 18:14:43 +00002866- Clear all free lists during a gc.collect() of the highest generation
2867 in order to allow pymalloc to free more arenas. Python may give back
2868 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002869
Georg Brandl3ee81df2008-05-17 18:14:43 +00002870- Issue #2045: Fix an infinite recursion triggered when printing a
2871 subclass of collections.defaultdict, if its default_factory is set
2872 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002873
Christian Heimesf75dbef2008-02-08 00:11:31 +00002874- Fixed a minor memory leak in dictobject.c. The content of the free
2875 list was not freed on interpreter shutdown.
2876
Georg Brandl5a7eca12010-03-21 19:29:04 +00002877- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002878 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002879
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2881 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002882 to compact the internal free lists of pre-allocted ints and floats.
2883
Georg Brandl3ee81df2008-05-17 18:14:43 +00002884- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2885 calls. Python expected the return type int but the fork familie
2886 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002887
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2898 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002899
Georg Brandl3ee81df2008-05-17 18:14:43 +00002900- Patch #1473257: generator objects gain a gi_code attribute. This is
2901 the same object as the func_code attribute of the function that
2902 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002903
Georg Brandl3ee81df2008-05-17 18:14:43 +00002904- Issue #1920: "while 0" statements were completely removed by the
2905 compiler, even in the presence of an "else" clause, which is
2906 supposed to be run when the condition is false. Now the compiler
2907 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002908
Guido van Rossumeead05f2008-01-24 18:21:02 +00002909- A few crashers fixed: weakref_in_del.py (issue #1377858);
2910 loosing_dict_ref.py (issue #1303614, test67.py);
2911 borrowed_ref_[34].py (not in tracker).
2912
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002913- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002914 suppressed while an extension is loaded by calling SetErrorMode in
2915 dynload_win.c. The error is still reported properly.
2916
Georg Brandl3ee81df2008-05-17 18:14:43 +00002917- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002918 several extension methods and modules do not work without unicode
2919 support.
2920
Georg Brandl26543b12008-01-21 18:36:51 +00002921- Issue #1882: when compiling code from a string, encoding cookies in the
2922 second line of code were not always recognized correctly.
2923
Georg Brandl14404b62008-01-19 19:27:05 +00002924- Issue #1679: "0x" was taken as a valid integer literal.
2925
Georg Brandl6caad7d2008-01-26 14:19:22 +00002926- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002927 added.
2928
Christian Heimesc94e2b52008-01-14 04:13:37 +00002929- sys.float_info / PyFloat_GetInfo: The floating point information
2930 object was converted from a dict to a specialized structseq object.
2931
Georg Brandl3ee81df2008-05-17 18:14:43 +00002932- Patch #1816: Added sys.flags structseq. It exposes the status of
2933 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002934
Georg Brandl3ee81df2008-05-17 18:14:43 +00002935- Objects/structseq.c: Implemented new structseq representation. The
2936 patch makes structseqs (e.g. the return value of os.stat) more
2937 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002938

Georg Brandl3ee81df2008-05-17 18:14:43 +00002947- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2948 envvar and sys.dont_write_bytecode attribute. All these can be set
2949 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002950
Georg Brandl3ee81df2008-05-17 18:14:43 +00002951- Improve some exception messages when Windows fails to load an
2952 extension module. Now we get for example '%1 is not a valid Win32
2953 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002960- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002961 and INF. float("nan"), float("inf") and float("-inf") now work on
2962 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002964- Compiler now generates simpler and faster code for dictionary
2965 literals. The oparg for BUILD_MAP now indicates an estimated
2966 dictionary size. There is a new opcode, STORE_MAP, for adding
2967 entries to the dictionary.

2997 file can now be directly executed by passing their name to the
2998 interpreter. The directory/zipfile is automatically inserted as the
2999 first entry in sys.path.

3002 function uses a generator expression when at the same time the
3003 executed code is closing a paused generator.

3010
Georg Brandl5a7eca12010-03-21 19:29:04 +00003011- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003012 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3013 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003014
Georg Brandl3ee81df2008-05-17 18:14:43 +00003015- Issue #1686386: Tuple's tp_repr did not take into account the
3016 possibility of having a self-referential tuple, which is possible
3017 from C code. Nor did object's tp_str consider that a type's tp_str
3018 could do something that could lead to an inifinite recursion.
3019 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3020 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003021
Georg Brandl3ee81df2008-05-17 18:14:43 +00003022- Issue #1164: It was possible to trigger deadlock when using the
3023 'print' statement to write to a file since the GIL was not released
3024 as needed. Now PyObject_Print() does the right thing along with
3025 various tp_print implementations of the built-in types and those in
3026 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003027
Georg Brandl3ee81df2008-05-17 18:14:43 +00003028- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00003034
Brett Cannon1e534b52007-09-07 04:18:30 +00003035- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036 PyObject_Call() never calling back out to Python code to trigger
3037 recursion depth updates/checks. Required the creation of a static
3038 RuntimeError instance in case normalizing an exception put the
3039 recursion check value past its limit. Fixes crashers
3040 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003041

Neal Norwitz0ac60192007-05-27 04:08:54 +00003055- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056 __*__ attributes. (Some already existed, e.g., __doc__ and
3057 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003058
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003059- Add -3 option to the interpreter to warn about features that are

3061
Georg Brandl2134e752007-05-21 20:34:16 +00003062- Patch #1686487: you can now pass any mapping after '**' in function
3063 calls.
3064
Collin Winter62903052007-05-18 23:11:24 +00003065- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003066 "except E as target:". This is to provide forwards compatibility
3067 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003074- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003075 setting a plain string, ie don't expand to single letter identifiers.
3076
Raymond Hettinger13936692007-04-11 18:40:58 +00003077- Request #1191699: Slices can now be pickled.
3078
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003079- Request #1193128: str.translate() now allows a None argument for
3080 translations that only remove characters without re-mapping the
3081 remaining characters.
3082
Georg Brandl5cb76c12007-03-21 09:00:39 +00003083- Patch #1682205: a TypeError while unpacking an iterable is no longer

3087
Guido van Rossum143b5642007-03-23 04:58:42 +00003088- Bug #1683368: The object.__init__() and object.__new__() methods are
3089 now stricter in rejecting excess arguments. The only time when
3090 either allows excess arguments is when it is not overridden and the
3091 other one is. For backwards compatibility, when both are
3092 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003093 warning later). Also, type.__init__() insists on the same signature
3094 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003095
Georg Brandl3ee81df2008-05-17 18:14:43 +00003096- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3097 object to complex using its __complex__() method before falling back
3098 to the __float__() method. Therefore, the functions in the cmath
3099 module now can operate on objects that define a __complex__()
3100 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003101
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102- Patch #1623563: allow __class__ assignment for classes with
3103 __slots__. The old and the new class are still required to have the
3104 same slot names.

3117
Georg Brandl7b9c5552007-03-12 14:30:05 +00003118- Bug #1678647: write a newline after printing an exception in any
3119 case, even when converting the value to a string failed.
3120
Georg Brandl871f1bc2007-03-12 13:17:36 +00003121- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122 its argument, if it exists. If not, it will work like before. This
3123 allows customizing the output of dir() in the presence of a
3124 __getattr__().

3133 parthensized forms. This means complex(repr(x)) now works instead of
3134 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003135
Georg Brandlaa2321b2007-03-07 00:40:28 +00003136- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137 makes the filenames the warning module prints much more sensible
3138 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003139

Georg Brandl0fca97a2007-03-05 22:28:08 +00003151- Patch #1674228: when assigning a slice (old-style), check for the
3152 sq_ass_slice instead of the sq_slice slot.
3153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- When printing an unraisable error, don't print exceptions. before
3155 the name. This duplicates the behavior whening normally printing
3156 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003298- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00003689 AttributeError instead of an IOError when the server's response
3690 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003691

Georg Brandl3ee81df2008-05-17 18:14:43 +00003707- Patch #1530482: add pydoc.render_doc() which returns the

3722
Georg Brandl92a6bae2007-03-13 17:43:32 +00003723- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003724 are set for invalid interpolation sequences that would lead to
3725 errors on reading back those values.

3779
Georg Brandl3ee81df2008-05-17 18:14:43 +00003780- unittest now verifies more of its assumptions. In particular,
3781 TestCase and TestSuite subclasses (not instances) are no longer
3782 accepted in TestSuite.addTest(). This should cause no
3783 incompatibility since it never made sense with ordinary subclasses
3784 -- the failure just occurred later, with a more cumbersome
3785 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004174 time so that opening a database previously created with the DB_DUP
4175 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4176 opens. Specifically: dictionary assignment to a DB object will
4177 replace all values for a given key when the database allows
4178 duplicate values. DB users should use DB.put(k, v) when they want
4179 to store duplicates; not DB[k] = v.

4186 characters with ASCII value less than 32. Also, it correctly quotes
4187 dots only if they occur on a single line, as opposed to the previous
4188 behavior of quoting dots if they are the second character of any
4189 line.

4535 of w# format code incorrectly truncated the length to an int, even
4536 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4537 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004567- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4568 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
