1339What's New in Python 2.6.1
1340==========================
1341
1342*Release date: 04-Dec-2008*
1343
1344Core and Builtins
1345-----------------
1346
1347- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1348 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1349 instead of throwing a MemoryError.
1350
1351- Issue #4367: Python would segfault during compiling when the unicodedata
1352 module couldn't be imported and \N escapes were present.
1353
1354- Issue #4348: Some bytearray methods returned that didn't cause any change to
1355 the bytearray, returned the same bytearray instead of a copy.
1356
1357- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1358
1359- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1360
1361- Issue #4048: The parser module now correctly validates relative imports.
1362
1363- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1370 __future__ import didn't work.
1371
1372- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1373 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1374 really executed because I cannot move to such directory on win2k)
1375
1376- Issue #4069: When set.remove(element) is used with a set element, the element
1377 is temporarily replaced with an equivalent frozenset. But the eventual
1378 KeyError would always report the empty frozenset([]) as the missing key. Now
1379 it correctly refers to the initial element.
1380

1382 again.

1530
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001531- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1532 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1533 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1534 ``printf`` function, whereas PyString_FromFormat has an independent
1535 implementation and uses "%zd" on all platforms for size_t values.
1536 This makes a difference on win64, where ``printf`` needs "%Id" to display

1558 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1560 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1561 type object.

1655
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001656- Issue #2975: When compiling several extension modules with Visual Studio 2008
1657 from the same python interpreter, some environment variables would grow
1658 without limit.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001697What's New in Python 2.6 beta 3?
1698================================
1699
Barry Warsaw07a4a382008-08-21 01:15:08 +00001700*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001701
1702Core and Builtins
1703-----------------
1704
Guido van Rossumf8402962008-08-20 15:01:50 +00001705- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1706 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1707 extensions do not automatically benefit from the class attribute
1708 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1709 to their tp_flags field if they care. This is a backwards
1710 compatibility feature; in 3.0, all types will use the cache by
1711 default.
1712
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001713- Keyword arguments can now follow starred arguments. (``f(a, *args,
1714 keyword=23)`` is now valid syntax.)
1715
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001716- ctypes function pointers that are COM methods have a boolean True
1717 value again.
1718
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001719- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1720 by denying s# to parse objects that have a releasebuffer procedure,
1721 and introducing s*.
1722
Georg Brandl1e13ea92008-08-11 09:07:59 +00001723- Issue #3537: Fix an assertion failure when an empty but presized dict
1724 object was stored in the freelist.
1725
Mark Dickinsonb6467572008-08-04 21:30:09 +00001726- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1727 ValueError consistently across platforms.
1728
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001729- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1730 (64bit Unix, for example), unichr() would truncate its argument and return
1731 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1732
Neal Norwitze7d8be82008-07-31 17:17:14 +00001733- Apply security patches from Apple.
1734
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001735- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1736 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1737
Antoine Pitrou92f82162008-07-25 22:22:08 +00001738- Issue #1819: function calls with several named parameters are now on
1739 average 35% faster (as measured by pybench).
1740
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001741- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1742 the python debugger steps into a class statement: the free variables (local
1743 variables defined in an outer scope) would be deleted from the outer scope.
1744
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001745- Issue #2620: Overflow checking when allocating or reallocating memory
1746 was not always being done properly in some python types and extension
1747 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1748 all been updated to perform better checks and places in the code that
1749 would previously leak memory on the error path when such an allocation
1750 failed have been fixed.
1751
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001752Library
1753-------
1754
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001755- Issue #3612: Added some missing basic types in ctypes.wintypes.
1756
Benjamin Petersone977ad42008-08-20 01:42:01 +00001757- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1758 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1759
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001760- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1761 version reported by these tools does not necessarily follow the python
1762 version numbering scheme, so the module is less strict when parsing it.
1763
Nick Coghlanf70385a2008-08-18 12:42:46 +00001764- Issue #2235: Added Py3k warnings for types which will become unhashable
1765 under the stricter __hash__ inheritance rules in 3.0. Several types
1766 which did not meet the rules for hash invariants and were already
1767 unhashable in 3.0 have now been explicitly flagged as unhashable in
1768 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1769 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1770
Brett Cannon88f801d2008-08-18 00:46:22 +00001771- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1772 imported into the module but exposed as part of the module's API.
1773
Brett Cannon7b96f072008-08-18 00:41:11 +00001774- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1775
Brett Cannon46225e72008-08-18 00:36:52 +00001776- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001778- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1779
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001780- Issue #3575: Incremental decoder's decode function now takes bytearray
1781 by using 's*' instead of 't#'.
1782
Jesus Cea585ad8a2009-07-02 15:37:21 +00001783- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001784 fails unicode conversion on 2nd parameter. (windows only)
1785
Facundo Batista94f243a2008-08-17 03:38:39 +00001786- Issue 2464. urllib2 now supports a malformation in the URL received
1787 in a redirect.
1788
Brett Cannonabe423e2008-08-16 21:47:07 +00001789- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001790 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001791
Facundo Batistaeb90b782008-08-16 14:44:07 +00001792- Issue #2776: fixed small issue when handling an URL with double slash
1793 after a 302 response in the case of not going through a proxy.
1794
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001795- Issue #2676: in the email package, content-type parsing was hanging on
1796 pathological input because of quadratic or exponential behaviour of a
1797 regular expression.
1798
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001799- Issue #3476: binary buffered reading through the new "io" library is now
1800 thread-safe.
1801
Brett Cannonbf3157b2008-08-14 05:00:03 +00001802- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1803 since mimetools itself is deprecated. Because modules are cached, all
1804 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1805
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001806- Issue #3134: shutil referenced undefined WindowsError symbol.
1807
Robert Schuppenies14646332008-08-10 11:01:53 +00001808- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1809 menu entries were not deleted.
1810
Brett Cannon83e81842008-08-09 23:30:55 +00001811- Copied the implementation of reduce() to _functools.reduce() to have a
1812 version that did not raise a DeprecationWarning under -3.
1813
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001814- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1815 a MemoryError rather than silently stop the iteration.
1816
Guido van Rossum59ce9012008-08-09 14:55:34 +00001817- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1818 to _sre.compile() will now be rejected. This should not affect anybody
1819 since the re.compile() function never generates invalid re-bytecode.
1820
Skip Montanaroa032bf42008-08-08 22:52:51 +00001821- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1822 upon first access it can be automatically initialized from the csv file if
1823 it wasn't initialized during instantiation.
1824
Brett Cannon3aa2a492008-08-06 22:28:09 +00001825- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1826 the reload() built-in has been removed.
1827
Brett Cannon7e30b672008-08-04 21:52:25 +00001828- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001829 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001840 asking for a specific length. This problem only affected files opened
1841 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001842

1867 file name rather than a ZipInfo instance, so files are extracted with
1868 mode 0600 rather than 000 under Unix.
1869
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001870- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1883 interaction with the tp_hash slot (added in 2.6b2) are now documented
1884
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001885- Issue #643841: The language reference now provides more detailed
1886 coverage of the lookup process for special methods. The disclaimers
1887 regarding lack of coverage of new-style classes have also been
1888 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001891What's New in Python 2.6 beta 2?
1892================================
1893
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001894*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001896Core and Builtins
1897-----------------
1898
Georg Brandl3e483f62008-07-16 22:57:41 +00001899- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1900 its methods now allow for items objects that can be converted to
1901 an integer using operator.index().
1902
Mark Dickinson64b7e502008-07-16 09:40:03 +00001903- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1904 produced a ValueError instead of giving the correct float.
1905
Eric Smitha5fa5a22008-07-16 00:11:49 +00001906- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1907 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1908
Mark Dickinson7103aa42008-07-15 19:08:33 +00001909- Issue #3008: the float type has a new instance method 'float.hex'
1910 and a new class method 'float.fromhex' to convert floating-point
1911 numbers to and from hexadecimal strings, respectively.
1912
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001913- Issue #2235: __hash__ is once again inherited by default. To allow
1914 collections.Hashable to remain meaningful in the presence of the
1915 default hash implementation (object.__hash__), it is now possible
1916 to explicit block inheritance of hash by setting __hash__=None at
1917 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1918 level.
1919
Nick Coghlanb028f502008-07-13 14:52:36 +00001920- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1921 the parent module cannot be found while performing an absolute import.
1922 This means that an incorrectly defined __package__ attribute will
1923 now only prevent relative imports in that module rather than causing
1924 all imports from that module to fail.
1925
Nick Coghlan14ff9942008-07-08 14:21:42 +00001926- Issue #2517: Allow unicode messages in Exceptions again by correctly
1927 bypassing the instance dictionary when looking up __unicode__ on
1928 new-style classes.
1929
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001930- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1931 set to a custom object whose write() method happens to install
1932 another file in sys.stdout.
1933
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001934- Issue #3088: Corrected a race condition in classes derived from
1935 threading.local: the first member set by a thread could be saved in
1936 another thread's dictionary.
1937
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001938- Issue #3004: Minor change to slice.indices(): the start and stop
1939 arguments are now treated identically, making the behaviour easier
1940 to describe and understand. For example, slice(None, -10,
1941 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1942 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1943 10, -1).
1944
Georg Brandl278fc502008-07-19 12:46:12 +00001945- Issue #3219: Calling a function with repeated keyword arguments,
1946 f(a=2, a=23), would not cause a syntax error. This was a regression
1947 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001948
Georg Brandl278fc502008-07-19 12:46:12 +00001949- Issue #2862: Make int and float freelist management consistent with
1950 other freelists. Changes their CompactFreeList apis into
1951 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001952

1954-------
1955
Thomas Heller57adf222008-08-14 19:10:48 +00001956- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1957 api functions without holding the GIL, which could lead to a fatal
1958 error when they failed.
1959
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001960- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001968- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1969 ForkingPickler.register() to resolve conflict with ctypes.
1970
Vinay Sajip51e65192008-07-18 09:01:10 +00001971- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001972
Thomas Heller880f5292008-07-15 19:39:38 +00001973- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1974 a valid dlerror() message.
1975
Thomas Heller2bad6572008-07-15 17:19:50 +00001976- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1977 incomplete structure was created.
1978

1982
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001983- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001984
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001985- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1986 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001987 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001988 content-length. The problem had been corrected in the 2.4 branch, but never
1989 merged into trunk.
1990
Georg Brandle78fbcc2008-07-05 10:13:36 +00001991- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00001999 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002000
Vinay Sajip51e65192008-07-18 09:01:10 +00002001- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002002 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002003
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002004- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2005 handling is now the same as that of other special attributes like __name__).
2006
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002007- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2008 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002459- Issue #1631171: Re-implement the 'warnings' module in C (the
2460 original Python code has been kept as backup). This will allow for
2461 using the 'warning's machinery in such places as the parser where
2462 use of pure Python code is not possible. Both the ``showarning()``
2463 and ``formatwarning()`` gain an optional 'line' argument which is
2464 not called by default for backwards-compatibility reasons. Setting
2465 ``warnings.showwarning()`` to an implementation that lacks support
2466 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002529- Issue #2550: The approach used by client/server code for obtaining
2530 ports to listen on in network-oriented tests has been refined in an
2531 effort to facilitate running multiple instances of the entire
2532 regression test suite in parallel without issue.
2533 test_support.bind_port() has been fixed such that it will always
2534 return a unique port -- which wasn't always the case with the
2535 previous implementation, especially if socket options had been set
2536 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2537 new implementation of bind_port() will actually raise an exception
2538 if it is passed an AF_INET/SOCK_STREAM socket with either the
2539 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2540 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2541 the socket it's been passed. This currently only applies to
2542 Windows. This option prevents any other sockets from binding to the
2543 host/port we've bound to, thus removing the possibility of the
2544 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2545 when a second SOCK_STREAM socket binds and accepts to a host/port
2546 that's already been bound by another socket. The optional preferred
2547 port parameter to bind_port() has been removed. Under no
2548 circumstances should tests be hard coding ports!
2549
2550 test_support.find_unused_port() has also been introduced, which will
2551 pass a temporary socket object to bind_port() in order to obtain an
2552 unused port. The temporary socket object is then closed and
2553 deleted, and the port is returned. This method should only be used
2554 for obtaining an unused port in order to pass to an external program
2555 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2556 a parameter to a server-oriented class that doesn't give you direct
2557 access to the underlying socket used.
2558
2559 Finally, test_support.HOST has been introduced, which should be used
2560 for the host argument of any relevant socket calls (i.e. bind and
2561 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002562
2563 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002564 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002565 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2566 test_asynchat and test_socket_ssl.
2567
Georg Brandl3ee81df2008-05-17 18:14:43 +00002568 It is now possible for multiple instances of the regression test
2569 suite to run in parallel without issue.

2836-----------------
2837
Fred Drakea8ee94b2008-03-01 02:45:07 +00002838- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002839 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002844
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002845- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002846 issue 215555 for a discussion.
2847
Eric Smitha73fbe72008-02-23 03:09:44 +00002848- Added the future_builtins module, which contains hex() and oct().
2849 These are the PEP 3127 version of these functions, designed to be
2850 compatible with the hex() and oct() builtins from Python 3.0. They
2851 differ slightly in their output formats from the existing, unchanged
2852 Python 2.6 builtins. The expected usage of the future_builtins
2853 module is:
2854 from future_builtins import hex, oct
2855
Eric Smith7ef40bf2008-02-20 23:34:22 +00002856- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2857 exponents for exponents with absolute value < 100. Follows C99
2858 standard. This is a change on Windows, which would use 3 digits.
2859 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2860 so that any alterations it does to the resulting string will be
2861 available in stringlib/formatter.h (for float.__format__).
2862
Eric Smith5a3c1352008-02-19 13:21:56 +00002863- Implemented PEP 3101, Advanced String Formatting. This adds a new
2864 builtin format(); a format() method for str and unicode; a
2865 __format__() method to object, str, unicode, int, long, float, and
2866 datetime; the class string.Formatter; and the C API
2867 PyObject_Format().
2868
Georg Brandl3ee81df2008-05-17 18:14:43 +00002869- Fixed several potential crashes, all caused by specially crafted
2870 __del__ methods exploiting objects in temporarily inconsistent
2871 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002872
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002873- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002874 prevent a possible crash: an Abstract Base Class would try to access
2875 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Clear all free lists during a gc.collect() of the highest generation
2881 in order to allow pymalloc to free more arenas. Python may give back
2882 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002883
Georg Brandl3ee81df2008-05-17 18:14:43 +00002884- Issue #2045: Fix an infinite recursion triggered when printing a
2885 subclass of collections.defaultdict, if its default_factory is set
2886 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002887
Christian Heimesf75dbef2008-02-08 00:11:31 +00002888- Fixed a minor memory leak in dictobject.c. The content of the free
2889 list was not freed on interpreter shutdown.
2890
Georg Brandl5a7eca12010-03-21 19:29:04 +00002891- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00002893
Georg Brandl3ee81df2008-05-17 18:14:43 +00002894- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2895 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002896 to compact the internal free lists of pre-allocted ints and floats.
2897
Georg Brandl3ee81df2008-05-17 18:14:43 +00002898- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2899 calls. Python expected the return type int but the fork familie
2900 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002901

2912 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002913
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914- Patch #1473257: generator objects gain a gi_code attribute. This is
2915 the same object as the func_code attribute of the function that
2916 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002917
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918- Issue #1920: "while 0" statements were completely removed by the
2919 compiler, even in the presence of an "else" clause, which is
2920 supposed to be run when the condition is false. Now the compiler
2921 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002922
Guido van Rossumeead05f2008-01-24 18:21:02 +00002923- A few crashers fixed: weakref_in_del.py (issue #1377858);
2924 loosing_dict_ref.py (issue #1303614, test67.py);
2925 borrowed_ref_[34].py (not in tracker).
2926
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002927- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002928 suppressed while an extension is loaded by calling SetErrorMode in

2930
Georg Brandl3ee81df2008-05-17 18:14:43 +00002931- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002932 several extension methods and modules do not work without unicode
2933 support.
2934
Georg Brandl26543b12008-01-21 18:36:51 +00002935- Issue #1882: when compiling code from a string, encoding cookies in the

2937
Georg Brandl14404b62008-01-19 19:27:05 +00002938- Issue #1679: "0x" was taken as a valid integer literal.
2939
Georg Brandl6caad7d2008-01-26 14:19:22 +00002940- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002941 added.
2942
Christian Heimesc94e2b52008-01-14 04:13:37 +00002943- sys.float_info / PyFloat_GetInfo: The floating point information
2944 object was converted from a dict to a specialized structseq object.
2945
Georg Brandl3ee81df2008-05-17 18:14:43 +00002946- Patch #1816: Added sys.flags structseq. It exposes the status of
2947 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002948
Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- Objects/structseq.c: Implemented new structseq representation. The
2950 patch makes structseqs (e.g. the return value of os.stat) more
2951 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002952

2980 dictionary size. There is a new opcode, STORE_MAP, for adding
2981 entries to the dictionary.

3011 file can now be directly executed by passing their name to the
3012 interpreter. The directory/zipfile is automatically inserted as the
3013 first entry in sys.path.

3024
Georg Brandl5a7eca12010-03-21 19:29:04 +00003025- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003026 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3027 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003028
Georg Brandl3ee81df2008-05-17 18:14:43 +00003029- Issue #1686386: Tuple's tp_repr did not take into account the
3030 possibility of having a self-referential tuple, which is possible
3031 from C code. Nor did object's tp_str consider that a type's tp_str
3032 could do something that could lead to an inifinite recursion.
3033 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3034 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003035
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036- Issue #1164: It was possible to trigger deadlock when using the
3037 'print' statement to write to a file since the GIL was not released
3038 as needed. Now PyObject_Print() does the right thing along with
3039 various tp_print implementations of the built-in types and those in
3040 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003041

Brett Cannon1e534b52007-09-07 04:18:30 +00003049- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050 PyObject_Call() never calling back out to Python code to trigger
3051 recursion depth updates/checks. Required the creation of a static
3052 RuntimeError instance in case normalizing an exception put the
3053 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00003070 __*__ attributes. (Some already existed, e.g., __doc__ and
3071 __name__.)

3077 calls.
3078
Collin Winter62903052007-05-18 23:11:24 +00003079- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003080 "except E as target:". This is to provide forwards compatibility
3081 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003088- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003089 setting a plain string, ie don't expand to single letter identifiers.
3090
Raymond Hettinger13936692007-04-11 18:40:58 +00003091- Request #1191699: Slices can now be pickled.
3092
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003093- Request #1193128: str.translate() now allows a None argument for
3094 translations that only remove characters without re-mapping the
3095 remaining characters.
3096
Georg Brandl5cb76c12007-03-21 09:00:39 +00003097- Patch #1682205: a TypeError while unpacking an iterable is no longer

3101
Guido van Rossum143b5642007-03-23 04:58:42 +00003102- Bug #1683368: The object.__init__() and object.__new__() methods are
3103 now stricter in rejecting excess arguments. The only time when
3104 either allows excess arguments is when it is not overridden and the
3105 other one is. For backwards compatibility, when both are
3106 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003107 warning later). Also, type.__init__() insists on the same signature
3108 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3111 object to complex using its __complex__() method before falling back
3112 to the __float__() method. Therefore, the functions in the cmath
3113 module now can operate on objects that define a __complex__()
3114 method.

3131
Georg Brandl7b9c5552007-03-12 14:30:05 +00003132- Bug #1678647: write a newline after printing an exception in any
3133 case, even when converting the value to a string failed.
3134
Georg Brandl871f1bc2007-03-12 13:17:36 +00003135- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136 its argument, if it exists. If not, it will work like before. This
3137 allows customizing the output of dir() in the presence of a
3138 __getattr__().

3147 parthensized forms. This means complex(repr(x)) now works instead of
3148 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003149
Georg Brandlaa2321b2007-03-07 00:40:28 +00003150- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003151 makes the filenames the warning module prints much more sensible
3152 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003165- Patch #1674228: when assigning a slice (old-style), check for the
3166 sq_ass_slice instead of the sq_slice slot.
3167
Georg Brandl3ee81df2008-05-17 18:14:43 +00003168- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003703 AttributeError instead of an IOError when the server's response
3704 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003705

Georg Brandl3ee81df2008-05-17 18:14:43 +00003721- Patch #1530482: add pydoc.render_doc() which returns the

3736
Georg Brandl92a6bae2007-03-13 17:43:32 +00003737- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003738 are set for invalid interpolation sequences that would lead to
3739 errors on reading back those values.

3782 returned string up to the first NUL character.

3793
Georg Brandl3ee81df2008-05-17 18:14:43 +00003794- unittest now verifies more of its assumptions. In particular,
3795 TestCase and TestSuite subclasses (not instances) are no longer
3796 accepted in TestSuite.addTest(). This should cause no
3797 incompatibility since it never made sense with ordinary subclasses
3798 -- the failure just occurred later, with a more cumbersome
3799 exception.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004187- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188 time so that opening a database previously created with the DB_DUP
4189 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4190 opens. Specifically: dictionary assignment to a DB object will
4191 replace all values for a given key when the database allows
4192 duplicate values. DB users should use DB.put(k, v) when they want
4193 to store duplicates; not DB[k] = v.

4200 characters with ASCII value less than 32. Also, it correctly quotes
4201 dots only if they occur on a single line, as opposed to the previous
4202 behavior of quoting dots if they are the second character of any
4203 line.

4549 of w# format code incorrectly truncated the length to an int, even
4550 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4551 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004581- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4582 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
