25 processing: any non-float non-integer argument is now converted to
26 an integer (if possible) using its __int__ method. Previously, only
27 small arguments were treated this way; larger arguments (those whose
28 __int__ was outside the range of a C long) would produce a TypeError.

53- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
54 embedders of the interpreter to set sys.argv without also modifying

109

120 Decimal operation raises multiple signals and more than one of those
121 signals is trapped, the specification determines the order in which
122 the signals should be handled. In many cases this order wasn't
123 being followed, leading to the wrong Python exception being raised.

1310 302 conformant loader) will now work correctly in most cases (they

1471What's New in Python 2.6.1
1472==========================
1473
1474*Release date: 04-Dec-2008*
1475
1476Core and Builtins
1477-----------------
1478
1479- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1480 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1481 instead of throwing a MemoryError.
1482
1483- Issue #4367: Python would segfault during compiling when the unicodedata
1484 module couldn't be imported and \N escapes were present.
1485
1486- Issue #4348: Some bytearray methods returned that didn't cause any change to
1487 the bytearray, returned the same bytearray instead of a copy.
1488
1489- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1490
1491- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1492
1493- Issue #4048: The parser module now correctly validates relative imports.
1494
1495- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1496 exec statement.
1497
1498- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1499 method does not return iterators for the 4th and 5th items.
1500
1501- Issue #4209: Enabling unicode_literals and the print_function in the same
1502 __future__ import didn't work.
1503
1504- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1505 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1506 really executed because I cannot move to such directory on win2k)
1507
1508- Issue #4069: When set.remove(element) is used with a set element, the element
1509 is temporarily replaced with an equivalent frozenset. But the eventual
1510 KeyError would always report the empty frozenset([]) as the missing key. Now
1511 it correctly refers to the initial element.
1512
1513- Fixed C99 style comments in several files. Python is now C89 compatible
1514 again.

1596 true singleton object.
1597
Brett Cannonb2d61bd2008-09-29 03:41:21 +00001598- Issue #3895: It was possible to crash the interpreter when an external timer

1642 AttributeError instead of RuntimeError, depending in which C API call
1643 exactly the recursion limit is exceeded. Consequently, both exception types

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001661- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1662
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001663- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1664 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1665 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1666 ``printf`` function, whereas PyString_FromFormat has an independent
1667 implementation and uses "%zd" on all platforms for size_t values.
1668 This makes a difference on win64, where ``printf`` needs "%Id" to display
1669 64bit values.
1670
Benjamin Peterson97179b02008-09-09 20:55:01 +00001671- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1675 object; previously an int would be returned for small values. the __long__
1676 method is allowed to return either an int or a long, but the behaviour of
1677 float objects should not change to respect backward compatibility.
1678
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001679- Issue #3751: str.rpartition would perform a left-partition when called with
1680 a unicode argument.
1681
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001682- Issue #3683: Fix compilation when --without-threads is given.
1683
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001684- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001685 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001686 was correctly parsed but parsing of subsequent arguments failed.
1687
Vinay Sajip35e3b032008-09-01 14:33:59 +00001688- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001689 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1690 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1691 when given a tuple of classes as second argument, were looking up
1692 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1693 type object.
1694
Neal Norwitz18aa3882008-08-24 05:04:52 +00001695- Fix crashes on memory allocation failure found with failmalloc.
1696
1697- Fix memory leaks found with valgrind and update suppressions file.
1698
1699- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1700
1701- Fix problem using wrong name in decimal module reported by pychecker.

1710 library targets in the Makefile.
1711
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001712- Issue #1204: The configure script now tests for additional libraries
1713 that may be required when linking against readline. This fixes issues
1714 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1733 with statements, or when the methods are invoked in the wrong order.
1734
Vinay Sajip844f7412008-09-09 13:42:08 +00001735- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

Nick Coghland2e09382008-09-11 12:11:06 +00001737- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001738 return a list or None rather than a custom object.
1739
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001740- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1764 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1765 for catch_warnings() also led to an improvement in the raising of a
1766 DeprecationWarning related to warnings.warn_explicit().
1767

1835-----------------
1836
Guido van Rossumf8402962008-08-20 15:01:50 +00001837- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1838 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1839 extensions do not automatically benefit from the class attribute
1840 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1841 to their tp_flags field if they care. This is a backwards
1842 compatibility feature; in 3.0, all types will use the cache by
1843 default.
1844
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001845- Keyword arguments can now follow starred arguments. (``f(a, *args,
1846 keyword=23)`` is now valid syntax.)
1847
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001848- ctypes function pointers that are COM methods have a boolean True
1849 value again.
1850
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001851- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1852 by denying s# to parse objects that have a releasebuffer procedure,
1853 and introducing s*.
1854
Georg Brandl1e13ea92008-08-11 09:07:59 +00001855- Issue #3537: Fix an assertion failure when an empty but presized dict
1856 object was stored in the freelist.
1857
Mark Dickinsonb6467572008-08-04 21:30:09 +00001858- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1859 ValueError consistently across platforms.
1860
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001861- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1862 (64bit Unix, for example), unichr() would truncate its argument and return
1863 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1864
Neal Norwitze7d8be82008-07-31 17:17:14 +00001865- Apply security patches from Apple.
1866
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001867- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1868 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1869
Antoine Pitrou92f82162008-07-25 22:22:08 +00001870- Issue #1819: function calls with several named parameters are now on
1871 average 35% faster (as measured by pybench).
1872
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001873- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1874 the python debugger steps into a class statement: the free variables (local

Gregory P. Smith0470bab2008-07-22 04:46:32 +00001877- Issue #2620: Overflow checking when allocating or reallocating memory
1878 was not always being done properly in some python types and extension
1879 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1880 all been updated to perform better checks and places in the code that
1881 would previously leak memory on the error path when such an allocation
1882 failed have been fixed.

1888
Benjamin Petersone977ad42008-08-20 01:42:01 +00001889- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1890 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1891
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001892- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1893 version reported by these tools does not necessarily follow the python
1894 version numbering scheme, so the module is less strict when parsing it.
1895
Nick Coghlanf70385a2008-08-18 12:42:46 +00001896- Issue #2235: Added Py3k warnings for types which will become unhashable
1897 under the stricter __hash__ inheritance rules in 3.0. Several types
1898 which did not meet the rules for hash invariants and were already
1899 unhashable in 3.0 have now been explicitly flagged as unhashable in
1900 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1901 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1902
Brett Cannon88f801d2008-08-18 00:46:22 +00001903- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1913 by using 's*' instead of 't#'.
1914
Jesus Cea585ad8a2009-07-02 15:37:21 +00001915- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001916 fails unicode conversion on 2nd parameter. (windows only)
1917
Facundo Batista94f243a2008-08-17 03:38:39 +00001918- Issue 2464. urllib2 now supports a malformation in the URL received
1919 in a redirect.

Facundo Batistaeb90b782008-08-16 14:44:07 +00001924- Issue #2776: fixed small issue when handling an URL with double slash
1925 after a 302 response in the case of not going through a proxy.
1926
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001927- Issue #2676: in the email package, content-type parsing was hanging on
1928 pathological input because of quadratic or exponential behaviour of a
1929 regular expression.
1930
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001931- Issue #3476: binary buffered reading through the new "io" library is now
1932 thread-safe.
1933
Brett Cannonbf3157b2008-08-14 05:00:03 +00001934- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1935 since mimetools itself is deprecated. Because modules are cached, all
1936 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1937
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001938- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001940- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1941 menu entries were not deleted.
1942
Brett Cannon83e81842008-08-09 23:30:55 +00001943- Copied the implementation of reduce() to _functools.reduce() to have a
1944 version that did not raise a DeprecationWarning under -3.
1945
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001946- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1947 a MemoryError rather than silently stop the iteration.
1948
Guido van Rossum59ce9012008-08-09 14:55:34 +00001949- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1950 to _sre.compile() will now be rejected. This should not affect anybody
1951 since the re.compile() function never generates invalid re-bytecode.
1952
Skip Montanaroa032bf42008-08-08 22:52:51 +00001953- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1954 upon first access it can be automatically initialized from the csv file if
1955 it wasn't initialized during instantiation.
1956
Brett Cannon3aa2a492008-08-06 22:28:09 +00001957- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1958 the reload() built-in has been removed.
1959
Brett Cannon7e30b672008-08-04 21:52:25 +00001960- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001961 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1969 raised an AttributeError.
1970
Benjamin Peterson01a24322008-07-28 23:35:27 +00001971- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001972 asking for a specific length. This problem only affected files opened
1973 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001974
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001975- Issue #3449: Update decimal module to use most recent specification

1997
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001998- Issue #3394: zipfile.writestr sets external attributes when passed a
1999 file name rather than a ZipInfo instance, so files are extracted with
2000 mode 0600 rather than 000 under Unix.
2001
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002002- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2003 argument in python 2.5, this broke code that subclassed Popen to include its
2004 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002014- Issue #2235: the C API function PyObject_HashNotImplemented and its
2015 interaction with the tp_hash slot (added in 2.6b2) are now documented
2016
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002017- Issue #643841: The language reference now provides more detailed
2018 coverage of the lookup process for special methods. The disclaimers
2019 regarding lack of coverage of new-style classes have also been
2020 removed, since the coverage is now fairly reasonable.

2024================================
2025
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002026*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002028Core and Builtins
2029-----------------
2030
Georg Brandl3e483f62008-07-16 22:57:41 +00002031- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2032 its methods now allow for items objects that can be converted to
2033 an integer using operator.index().
2034
Mark Dickinson64b7e502008-07-16 09:40:03 +00002035- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2036 produced a ValueError instead of giving the correct float.
2037
Eric Smitha5fa5a22008-07-16 00:11:49 +00002038- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2039 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2040
Mark Dickinson7103aa42008-07-15 19:08:33 +00002041- Issue #3008: the float type has a new instance method 'float.hex'
2042 and a new class method 'float.fromhex' to convert floating-point
2043 numbers to and from hexadecimal strings, respectively.
2044
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002045- Issue #2235: __hash__ is once again inherited by default. To allow
2046 collections.Hashable to remain meaningful in the presence of the
2047 default hash implementation (object.__hash__), it is now possible
2048 to explicit block inheritance of hash by setting __hash__=None at
2049 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2050 level.
2051
Nick Coghlanb028f502008-07-13 14:52:36 +00002052- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2053 the parent module cannot be found while performing an absolute import.
2054 This means that an incorrectly defined __package__ attribute will
2055 now only prevent relative imports in that module rather than causing
2056 all imports from that module to fail.
2057
Nick Coghlan14ff9942008-07-08 14:21:42 +00002058- Issue #2517: Allow unicode messages in Exceptions again by correctly
2059 bypassing the instance dictionary when looking up __unicode__ on
2060 new-style classes.
2061
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002062- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2063 set to a custom object whose write() method happens to install
2064 another file in sys.stdout.
2065
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002066- Issue #3088: Corrected a race condition in classes derived from
2067 threading.local: the first member set by a thread could be saved in
2068 another thread's dictionary.
2069
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002070- Issue #3004: Minor change to slice.indices(): the start and stop
2071 arguments are now treated identically, making the behaviour easier
2072 to describe and understand. For example, slice(None, -10,
2073 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2074 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2075 10, -1).
2076
Georg Brandl278fc502008-07-19 12:46:12 +00002077- Issue #3219: Calling a function with repeated keyword arguments,
2078 f(a=2, a=23), would not cause a syntax error. This was a regression
2079 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002080
Georg Brandl278fc502008-07-19 12:46:12 +00002081- Issue #2862: Make int and float freelist management consistent with
2082 other freelists. Changes their CompactFreeList apis into
2083 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002088- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2089 api functions without holding the GIL, which could lead to a fatal
2090 error when they failed.
2091
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002092- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002100- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2101 ForkingPickler.register() to resolve conflict with ctypes.
2102
Vinay Sajip51e65192008-07-18 09:01:10 +00002103- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00002105- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2106 a valid dlerror() message.
2107
Thomas Heller2bad6572008-07-15 17:19:50 +00002108- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2109 incomplete structure was created.
2110

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002115- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002116
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002117- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2118 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002119 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002120 content-length. The problem had been corrected in the 2.4 branch, but never
2121 merged into trunk.
2122
Georg Brandle78fbcc2008-07-05 10:13:36 +00002123- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002134 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002135
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002136- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2137 handling is now the same as that of other special attributes like __name__).
2138
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002139- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2140 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002529 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002530
2531 This is controlled by the configure argument ``--with-universal-archs``:
2532
2533 - ``--with-universal-archs=all``: install 4-way universal
2534
2535 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2536
2537 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2538
2539 This option should be used in combination with ``--enable-universalsdk=``.
2540
2541 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002591- Issue #1631171: Re-implement the 'warnings' module in C (the
2592 original Python code has been kept as backup). This will allow for
2593 using the 'warning's machinery in such places as the parser where
2594 use of pure Python code is not possible. Both the ``showarning()``
2595 and ``formatwarning()`` gain an optional 'line' argument which is
2596 not called by default for backwards-compatibility reasons. Setting
2597 ``warnings.showwarning()`` to an implementation that lacks support
2598 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002661- Issue #2550: The approach used by client/server code for obtaining
2662 ports to listen on in network-oriented tests has been refined in an
2663 effort to facilitate running multiple instances of the entire
2664 regression test suite in parallel without issue.
2665 test_support.bind_port() has been fixed such that it will always
2666 return a unique port -- which wasn't always the case with the
2667 previous implementation, especially if socket options had been set
2668 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2669 new implementation of bind_port() will actually raise an exception
2670 if it is passed an AF_INET/SOCK_STREAM socket with either the
2671 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2672 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2673 the socket it's been passed. This currently only applies to
2674 Windows. This option prevents any other sockets from binding to the
2675 host/port we've bound to, thus removing the possibility of the
2676 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2677 when a second SOCK_STREAM socket binds and accepts to a host/port
2678 that's already been bound by another socket. The optional preferred
2679 port parameter to bind_port() has been removed. Under no
2680 circumstances should tests be hard coding ports!
2681
2682 test_support.find_unused_port() has also been introduced, which will
2683 pass a temporary socket object to bind_port() in order to obtain an
2684 unused port. The temporary socket object is then closed and
2685 deleted, and the port is returned. This method should only be used
2686 for obtaining an unused port in order to pass to an external program
2687 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2688 a parameter to a server-oriented class that doesn't give you direct
2689 access to the underlying socket used.
2690
2691 Finally, test_support.HOST has been introduced, which should be used
2692 for the host argument of any relevant socket calls (i.e. bind and
2693 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002694
2695 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002696 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002697 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2698 test_asynchat and test_socket_ssl.
2699
Georg Brandl3ee81df2008-05-17 18:14:43 +00002700 It is now possible for multiple instances of the regression test

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002977- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002978 issue 215555 for a discussion.
2979
Eric Smitha73fbe72008-02-23 03:09:44 +00002980- Added the future_builtins module, which contains hex() and oct().
2981 These are the PEP 3127 version of these functions, designed to be
2982 compatible with the hex() and oct() builtins from Python 3.0. They
2983 differ slightly in their output formats from the existing, unchanged
2984 Python 2.6 builtins. The expected usage of the future_builtins
2985 module is:
2986 from future_builtins import hex, oct
2987
Eric Smith7ef40bf2008-02-20 23:34:22 +00002988- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2989 exponents for exponents with absolute value < 100. Follows C99
2990 standard. This is a change on Windows, which would use 3 digits.
2991 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2992 so that any alterations it does to the resulting string will be
2993 available in stringlib/formatter.h (for float.__format__).
2994
Eric Smith5a3c1352008-02-19 13:21:56 +00002995- Implemented PEP 3101, Advanced String Formatting. This adds a new
2996 builtin format(); a format() method for str and unicode; a
2997 __format__() method to object, str, unicode, int, long, float, and
2998 datetime; the class string.Formatter; and the C API
2999 PyObject_Format().
3000
Georg Brandl3ee81df2008-05-17 18:14:43 +00003001- Fixed several potential crashes, all caused by specially crafted
3002 __del__ methods exploiting objects in temporarily inconsistent
3003 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003004
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003005- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003006 prevent a possible crash: an Abstract Base Class would try to access
3007 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003008
Georg Brandl3ee81df2008-05-17 18:14:43 +00003009- Fixed repr() and str() of complex numbers with infinity or nan as
3010 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003012- Clear all free lists during a gc.collect() of the highest generation
3013 in order to allow pymalloc to free more arenas. Python may give back
3014 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003015
Georg Brandl3ee81df2008-05-17 18:14:43 +00003016- Issue #2045: Fix an infinite recursion triggered when printing a
3017 subclass of collections.defaultdict, if its default_factory is set
3018 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003019
Christian Heimesf75dbef2008-02-08 00:11:31 +00003020- Fixed a minor memory leak in dictobject.c. The content of the free
3021 list was not freed on interpreter shutdown.
3022
Georg Brandl5a7eca12010-03-21 19:29:04 +00003023- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003024 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003025
Georg Brandl3ee81df2008-05-17 18:14:43 +00003026- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3027 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003028 to compact the internal free lists of pre-allocted ints and floats.
3029
Georg Brandl3ee81df2008-05-17 18:14:43 +00003030- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3031 calls. Python expected the return type int but the fork familie
3032 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003033
Georg Brandl3ee81df2008-05-17 18:14:43 +00003034- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3044 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003045
Georg Brandl3ee81df2008-05-17 18:14:43 +00003046- Patch #1473257: generator objects gain a gi_code attribute. This is
3047 the same object as the func_code attribute of the function that
3048 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003049
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050- Issue #1920: "while 0" statements were completely removed by the
3051 compiler, even in the presence of an "else" clause, which is
3052 supposed to be run when the condition is false. Now the compiler
3053 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003054
Guido van Rossumeead05f2008-01-24 18:21:02 +00003055- A few crashers fixed: weakref_in_del.py (issue #1377858);
3056 loosing_dict_ref.py (issue #1303614, test67.py);
3057 borrowed_ref_[34].py (not in tracker).
3058
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003059- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003060 suppressed while an extension is loaded by calling SetErrorMode in
3061 dynload_win.c. The error is still reported properly.
3062
Georg Brandl3ee81df2008-05-17 18:14:43 +00003063- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003064 several extension methods and modules do not work without unicode
3065 support.
3066
Georg Brandl26543b12008-01-21 18:36:51 +00003067- Issue #1882: when compiling code from a string, encoding cookies in the
3068 second line of code were not always recognized correctly.
3069
Georg Brandl14404b62008-01-19 19:27:05 +00003070- Issue #1679: "0x" was taken as a valid integer literal.
3071
Georg Brandl6caad7d2008-01-26 14:19:22 +00003072- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003073 added.
3074
Christian Heimesc94e2b52008-01-14 04:13:37 +00003075- sys.float_info / PyFloat_GetInfo: The floating point information
3076 object was converted from a dict to a specialized structseq object.
3077
Georg Brandl3ee81df2008-05-17 18:14:43 +00003078- Patch #1816: Added sys.flags structseq. It exposes the status of
3079 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003080
Georg Brandl3ee81df2008-05-17 18:14:43 +00003081- Objects/structseq.c: Implemented new structseq representation. The
3082 patch makes structseqs (e.g. the return value of os.stat) more
3083 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003084
Georg Brandl3ee81df2008-05-17 18:14:43 +00003085- Patch #1700288: added a type attribute cache that caches method
3086 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003087
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003088- Bug #1776: __import__() no longer accepts filenames on any platform.

3092
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3094 envvar and sys.dont_write_bytecode attribute. All these can be set
3095 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003096
Georg Brandl3ee81df2008-05-17 18:14:43 +00003097- Improve some exception messages when Windows fails to load an
3098 extension module. Now we get for example '%1 is not a valid Win32
3099 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003106- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107 and INF. float("nan"), float("inf") and float("-inf") now work on
3108 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Compiler now generates simpler and faster code for dictionary
3111 literals. The oparg for BUILD_MAP now indicates an estimated
3112 dictionary size. There is a new opcode, STORE_MAP, for adding
3113 entries to the dictionary.

3156
Georg Brandl5a7eca12010-03-21 19:29:04 +00003157- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3159 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Issue #1686386: Tuple's tp_repr did not take into account the
3162 possibility of having a self-referential tuple, which is possible
3163 from C code. Nor did object's tp_str consider that a type's tp_str
3164 could do something that could lead to an inifinite recursion.
3165 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3166 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003167
Georg Brandl3ee81df2008-05-17 18:14:43 +00003168- Issue #1164: It was possible to trigger deadlock when using the
3169 'print' statement to write to a file since the GIL was not released
3170 as needed. Now PyObject_Print() does the right thing along with
3171 various tp_print implementations of the built-in types and those in
3172 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003173
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00003181- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182 PyObject_Call() never calling back out to Python code to trigger
3183 recursion depth updates/checks. Required the creation of a static
3184 RuntimeError instance in case normalizing an exception put the
3185 recursion check value past its limit. Fixes crashers

Georg Brandl2134e752007-05-21 20:34:16 +00003208- Patch #1686487: you can now pass any mapping after '**' in function
3209 calls.
3210
Collin Winter62903052007-05-18 23:11:24 +00003211- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003212 "except E as target:". This is to provide forwards compatibility
3213 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00003234- Bug #1683368: The object.__init__() and object.__new__() methods are
3235 now stricter in rejecting excess arguments. The only time when
3236 either allows excess arguments is when it is not overridden and the
3237 other one is. For backwards compatibility, when both are
3238 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003239 warning later). Also, type.__init__() insists on the same signature
3240 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003242- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3243 object to complex using its __complex__() method before falling back
3244 to the __float__() method. Therefore, the functions in the cmath
3245 module now can operate on objects that define a __complex__()
3246 method.

3266
Georg Brandl871f1bc2007-03-12 13:17:36 +00003267- The dir() function has been extended to call the __dir__() method on

3269 allows customizing the output of dir() in the presence of a

3280 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003282- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003283 makes the filenames the warning module prints much more sensible
3284 when a PYTHONSTARTUP file is used.

3299
Georg Brandl3ee81df2008-05-17 18:14:43 +00003300- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003835 AttributeError instead of an IOError when the server's response

3914 returned string up to the first NUL character.

3927 TestCase and TestSuite subclasses (not instances) are no longer
3928 accepted in TestSuite.addTest(). This should cause no

3930 -- the failure just occurred later, with a more cumbersome
3931 exception.

4210 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004211
Georg Brandl3ee81df2008-05-17 18:14:43 +00004212- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4213 with RFC 3207 and forgets any knowledge obtained from the server not
4214 obtained from the TLS negotiation itself. Patch contributed by Bill
4215 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004216
Georg Brandl3ee81df2008-05-17 18:14:43 +00004217- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004218 that the SMTP.starttls() caller no longer needs to call ehlo()
4219 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220 does not claim to support starttls. Adds the
4221 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4302 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4303 silently miscode subclasses of those types. Now, it raises a
4304 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004305

Georg Brandl3ee81df2008-05-17 18:14:43 +00004320 time so that opening a database previously created with the DB_DUP
4321 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4322 opens. Specifically: dictionary assignment to a DB object will
4323 replace all values for a given key when the database allows
4324 duplicate values. DB users should use DB.put(k, v) when they want
4325 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004326

4332 characters with ASCII value less than 32. Also, it correctly quotes
4333 dots only if they occur on a single line, as opposed to the previous
4334 behavior of quoting dots if they are the second character of any
4335 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004336

Georg Brandl3ee81df2008-05-17 18:14:43 +00004680- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4681 of w# format code incorrectly truncated the length to an int, even
4682 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4683 incorrect results with huge strings.

4703- Fix some leftovers from the conversion from int to Py_ssize_t
4704 (relevant to strings and sequences of more than 2**31 items).
4705
4706- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4707 outside of pystate.c and should not be necessary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004713- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4714 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004715
Georg Brandl3ee81df2008-05-17 18:14:43 +00004716- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004723- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4724 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4725 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4726 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004741- Removed the macfs module. It had been deprecated since Python 2.5.
4742 This lead to the deprecation of macostools.touched() as it relied
4743 solely on macfs and was a no-op under OS X.
