13-----------------
14
Ezio Melotti86e5e172010-07-03 05:34:39 +000015- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
16 start byte and the continuation byte(s) are now considered invalid, instead
17 of the number of bytes specified by the start byte.
18 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
19 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
20 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
21 Previous versions returned a single u'\ufffd'.
22
Benjamin Peterson8d649632010-06-22 19:21:33 +000023- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
24

26 the interpreter with characters outside the Basic Multilingual Plane
27 (higher than 0x10000).
28
Mark Dickinson80068da2010-06-05 11:59:41 +000029- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsonb671c292010-06-05 12:15:35 +000030 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
31 arises from the "Overriding __eq__ blocks inheritance ..." warning
32 when turned into an exception: in this case the exception simply
33 gets ignored.
Mark Dickinson80068da2010-06-05 11:59:41 +000034
Benjamin Peterson85633362010-06-08 14:58:25 +000035- In the unicode/str.format(), raise a ValueError when indexes to arguments are

Mark Dickinsone02c9d22010-05-07 13:23:18 +000047- Issue #1533: fix inconsistency in range function argument
48 processing: any non-float non-integer argument is now converted to
49 an integer (if possible) using its __int__ method. Previously, only
50 small arguments were treated this way; larger arguments (those whose
51 __int__ was outside the range of a C long) would produce a TypeError.
52
Benjamin Petersonc218ce82010-04-16 22:43:53 +000053- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
54 passed to bytearray.
55

67
Victor Stinner0217c952010-03-21 13:09:24 +000068- Issue #7820: The parser tokenizer restores all bytes in the right if
69 the BOM check fails.
70
Ronald Oussoren07466192010-04-18 14:34:22 +000071- Issue #7072: isspace(0xa0) is true on Mac OS X

74-----
75
76- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
77 embedders of the interpreter to set sys.argv without also modifying
78 sys.path. This helps fix `CVE-2008-5983
79 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

1549
1550*Release date: 04-Dec-2008*
1551
1552Core and Builtins
1553-----------------
1554
1555- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1556 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1557 instead of throwing a MemoryError.
1558
1559- Issue #4367: Python would segfault during compiling when the unicodedata
1560 module couldn't be imported and \N escapes were present.
1561
1562- Issue #4348: Some bytearray methods returned that didn't cause any change to
1563 the bytearray, returned the same bytearray instead of a copy.
1564
1565- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1566
1567- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1568
1569- Issue #4048: The parser module now correctly validates relative imports.
1570
1571- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1572 exec statement.
1573
1574- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1575 method does not return iterators for the 4th and 5th items.
1576
1577- Issue #4209: Enabling unicode_literals and the print_function in the same
1578 __future__ import didn't work.
1579
1580- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1581 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1582 really executed because I cannot move to such directory on win2k)
1583
1584- Issue #4069: When set.remove(element) is used with a set element, the element
1585 is temporarily replaced with an equivalent frozenset. But the eventual
1586 KeyError would always report the empty frozenset([]) as the missing key. Now
1587 it correctly refers to the initial element.
1588
1589- Fixed C99 style comments in several files. Python is now C89 compatible
1590 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001737- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1738
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001739- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1740 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1741 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1742 ``printf`` function, whereas PyString_FromFormat has an independent
1743 implementation and uses "%zd" on all platforms for size_t values.
1744 This makes a difference on win64, where ``printf`` needs "%Id" to display
1745 64bit values.
1746
Benjamin Peterson97179b02008-09-09 20:55:01 +00001747- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1751 object; previously an int would be returned for small values. the __long__
1752 method is allowed to return either an int or a long, but the behaviour of
1753 float objects should not change to respect backward compatibility.
1754
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001755- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001762 was correctly parsed but parsing of subsequent arguments failed.
1763
Vinay Sajip35e3b032008-09-01 14:33:59 +00001764- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001765 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1766 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1767 when given a tuple of classes as second argument, were looking up
1768 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1769 type object.
1770
Neal Norwitz18aa3882008-08-24 05:04:52 +00001771- Fix crashes on memory allocation failure found with failmalloc.
1772
1773- Fix memory leaks found with valgrind and update suppressions file.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001905What's New in Python 2.6 beta 3?
1906================================
1907
Barry Warsaw07a4a382008-08-21 01:15:08 +00001908*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001909
1910Core and Builtins
1911-----------------
1912
Guido van Rossumf8402962008-08-20 15:01:50 +00001913- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1914 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1915 extensions do not automatically benefit from the class attribute
1916 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1917 to their tp_flags field if they care. This is a backwards
1918 compatibility feature; in 3.0, all types will use the cache by
1919 default.
1920
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001921- Keyword arguments can now follow starred arguments. (``f(a, *args,
1922 keyword=23)`` is now valid syntax.)
1923
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001924- ctypes function pointers that are COM methods have a boolean True
1925 value again.
1926
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001927- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1928 by denying s# to parse objects that have a releasebuffer procedure,
1929 and introducing s*.
1930
Georg Brandl1e13ea92008-08-11 09:07:59 +00001931- Issue #3537: Fix an assertion failure when an empty but presized dict
1932 object was stored in the freelist.
1933
Mark Dickinsonb6467572008-08-04 21:30:09 +00001934- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1935 ValueError consistently across platforms.
1936
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001937- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1938 (64bit Unix, for example), unichr() would truncate its argument and return
1939 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1940
Neal Norwitze7d8be82008-07-31 17:17:14 +00001941- Apply security patches from Apple.
1942
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001943- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1944 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1945
Antoine Pitrou92f82162008-07-25 22:22:08 +00001946- Issue #1819: function calls with several named parameters are now on
1947 average 35% faster (as measured by pybench).
1948
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001949- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1950 the python debugger steps into a class statement: the free variables (local
1951 variables defined in an outer scope) would be deleted from the outer scope.
1952
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001953- Issue #2620: Overflow checking when allocating or reallocating memory
1954 was not always being done properly in some python types and extension
1955 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1956 all been updated to perform better checks and places in the code that
1957 would previously leak memory on the error path when such an allocation
1958 failed have been fixed.
1959
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001960Library
1961-------
1962
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001963- Issue #3612: Added some missing basic types in ctypes.wintypes.
1964
Benjamin Petersone977ad42008-08-20 01:42:01 +00001965- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1966 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1967
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001968- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1969 version reported by these tools does not necessarily follow the python
1970 version numbering scheme, so the module is less strict when parsing it.
1971
Nick Coghlanf70385a2008-08-18 12:42:46 +00001972- Issue #2235: Added Py3k warnings for types which will become unhashable
1973 under the stricter __hash__ inheritance rules in 3.0. Several types
1974 which did not meet the rules for hash invariants and were already
1975 unhashable in 3.0 have now been explicitly flagged as unhashable in
1976 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1977 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1978
Brett Cannon88f801d2008-08-18 00:46:22 +00001979- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1980 imported into the module but exposed as part of the module's API.
1981
Brett Cannon7b96f072008-08-18 00:41:11 +00001982- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1983
Brett Cannon46225e72008-08-18 00:36:52 +00001984- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1985
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001986- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1987
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001988- Issue #3575: Incremental decoder's decode function now takes bytearray
1989 by using 's*' instead of 't#'.
1990
Jesus Cea585ad8a2009-07-02 15:37:21 +00001991- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001992 fails unicode conversion on 2nd parameter. (windows only)
1993
Facundo Batista94f243a2008-08-17 03:38:39 +00001994- Issue 2464. urllib2 now supports a malformation in the URL received
1995 in a redirect.
1996
Brett Cannonabe423e2008-08-16 21:47:07 +00001997- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001998 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001999
Facundo Batistaeb90b782008-08-16 14:44:07 +00002000- Issue #2776: fixed small issue when handling an URL with double slash
2001 after a 302 response in the case of not going through a proxy.
2002
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002003- Issue #2676: in the email package, content-type parsing was hanging on
2004 pathological input because of quadratic or exponential behaviour of a
2005 regular expression.
2006
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002007- Issue #3476: binary buffered reading through the new "io" library is now
2008 thread-safe.
2009
Brett Cannonbf3157b2008-08-14 05:00:03 +00002010- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2011 since mimetools itself is deprecated. Because modules are cached, all
2012 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2013
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002014- Issue #3134: shutil referenced undefined WindowsError symbol.
2015
Robert Schuppenies14646332008-08-10 11:01:53 +00002016- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2017 menu entries were not deleted.
2018
Brett Cannon83e81842008-08-09 23:30:55 +00002019- Copied the implementation of reduce() to _functools.reduce() to have a
2020 version that did not raise a DeprecationWarning under -3.
2021
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002022- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2023 a MemoryError rather than silently stop the iteration.
2024
Guido van Rossum59ce9012008-08-09 14:55:34 +00002025- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2026 to _sre.compile() will now be rejected. This should not affect anybody
2027 since the re.compile() function never generates invalid re-bytecode.
2028
Skip Montanaroa032bf42008-08-08 22:52:51 +00002029- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2030 upon first access it can be automatically initialized from the csv file if
2031 it wasn't initialized during instantiation.
2032
Brett Cannon3aa2a492008-08-06 22:28:09 +00002033- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2034 the reload() built-in has been removed.
2035
Brett Cannon7e30b672008-08-04 21:52:25 +00002036- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002037 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002044- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2045 raised an AttributeError.
2046
Benjamin Peterson01a24322008-07-28 23:35:27 +00002047- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002048 asking for a specific length. This problem only affected files opened
2049 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002050
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002051- Issue #3449: Update decimal module to use most recent specification
2052 (v. 1.68) and tests (v. 2.58) from IBM.
2053
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002054- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2062
2063- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2064 invalid arguments.
2065
2066- Issue #3302: Fix several crashes when calling locale's gettext functions
2067 with None arguments.
2068
2069- Issue #3389: Allow resolving dotted names for handlers in logging
2070 configuration files.
2071
2072- Deprecate the sunaudio module for removal in Python 3.0.
2073
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002074- Issue #3394: zipfile.writestr sets external attributes when passed a
2075 file name rather than a ZipInfo instance, so files are extracted with
2076 mode 0600 rather than 000 under Unix.
2077
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002078- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2079 argument in python 2.5, this broke code that subclassed Popen to include its
2080 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002090- Issue #2235: the C API function PyObject_HashNotImplemented and its
2091 interaction with the tp_hash slot (added in 2.6b2) are now documented
2092
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002093- Issue #643841: The language reference now provides more detailed
2094 coverage of the lookup process for special methods. The disclaimers
2095 regarding lack of coverage of new-style classes have also been
2096 removed, since the coverage is now fairly reasonable.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002102*Release date: 17-Jul-2008*

2105-----------------
2106
Georg Brandl3e483f62008-07-16 22:57:41 +00002107- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2108 its methods now allow for items objects that can be converted to
2109 an integer using operator.index().
2110
Mark Dickinson64b7e502008-07-16 09:40:03 +00002111- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2112 produced a ValueError instead of giving the correct float.
2113
Eric Smitha5fa5a22008-07-16 00:11:49 +00002114- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2115 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2116
Mark Dickinson7103aa42008-07-15 19:08:33 +00002117- Issue #3008: the float type has a new instance method 'float.hex'
2118 and a new class method 'float.fromhex' to convert floating-point
2119 numbers to and from hexadecimal strings, respectively.
2120
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002121- Issue #2235: __hash__ is once again inherited by default. To allow
2122 collections.Hashable to remain meaningful in the presence of the
2123 default hash implementation (object.__hash__), it is now possible
2124 to explicit block inheritance of hash by setting __hash__=None at
2125 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2126 level.
2127
Nick Coghlanb028f502008-07-13 14:52:36 +00002128- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2129 the parent module cannot be found while performing an absolute import.
2130 This means that an incorrectly defined __package__ attribute will
2131 now only prevent relative imports in that module rather than causing
2132 all imports from that module to fail.
2133
Nick Coghlan14ff9942008-07-08 14:21:42 +00002134- Issue #2517: Allow unicode messages in Exceptions again by correctly
2135 bypassing the instance dictionary when looking up __unicode__ on
2136 new-style classes.
2137
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002138- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

2144 another thread's dictionary.
2145
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002146- Issue #3004: Minor change to slice.indices(): the start and stop
2147 arguments are now treated identically, making the behaviour easier
2148 to describe and understand. For example, slice(None, -10,
2149 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2150 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2151 10, -1).
2152
Georg Brandl278fc502008-07-19 12:46:12 +00002153- Issue #3219: Calling a function with repeated keyword arguments,

2155 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002605 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002606
2607 This is controlled by the configure argument ``--with-universal-archs``:
2608
2609 - ``--with-universal-archs=all``: install 4-way universal
2610
2611 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2612
2613 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2614
2615 This option should be used in combination with ``--enable-universalsdk=``.

2654 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002667- Issue #1631171: Re-implement the 'warnings' module in C (the
2668 original Python code has been kept as backup). This will allow for
2669 using the 'warning's machinery in such places as the parser where
2670 use of pure Python code is not possible. Both the ``showarning()``
2671 and ``formatwarning()`` gain an optional 'line' argument which is
2672 not called by default for backwards-compatibility reasons. Setting
2673 ``warnings.showwarning()`` to an implementation that lacks support
2674 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002737- Issue #2550: The approach used by client/server code for obtaining
2738 ports to listen on in network-oriented tests has been refined in an
2739 effort to facilitate running multiple instances of the entire
2740 regression test suite in parallel without issue.
2741 test_support.bind_port() has been fixed such that it will always
2742 return a unique port -- which wasn't always the case with the
2743 previous implementation, especially if socket options had been set
2744 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2745 new implementation of bind_port() will actually raise an exception
2746 if it is passed an AF_INET/SOCK_STREAM socket with either the
2747 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2748 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2749 the socket it's been passed. This currently only applies to
2750 Windows. This option prevents any other sockets from binding to the
2751 host/port we've bound to, thus removing the possibility of the
2752 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2753 when a second SOCK_STREAM socket binds and accepts to a host/port
2754 that's already been bound by another socket. The optional preferred
2755 port parameter to bind_port() has been removed. Under no
2756 circumstances should tests be hard coding ports!
2757
2758 test_support.find_unused_port() has also been introduced, which will
2759 pass a temporary socket object to bind_port() in order to obtain an
2760 unused port. The temporary socket object is then closed and
2761 deleted, and the port is returned. This method should only be used
2762 for obtaining an unused port in order to pass to an external program
2763 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2764 a parameter to a server-oriented class that doesn't give you direct
2765 access to the underlying socket used.
2766
2767 Finally, test_support.HOST has been introduced, which should be used
2768 for the host argument of any relevant socket calls (i.e. bind and
2769 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002770
2771 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002772 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002773 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2774 test_asynchat and test_socket_ssl.
2775
Georg Brandl3ee81df2008-05-17 18:14:43 +00002776 It is now possible for multiple instances of the regression test
2777 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00002981- The bundled libffi copy is now in sync with the recently released
2982 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002983 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2984 files are used. On all linux systems the --with-system-ffi
2985 configure option defaults to "yes".

3045
Fred Drakea8ee94b2008-03-01 02:45:07 +00003046- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003047 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003049- Issue #2067: file.__exit__() now calls subclasses' close() method.
3050
3051- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003052
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003053- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003054 issue 215555 for a discussion.
3055
Eric Smitha73fbe72008-02-23 03:09:44 +00003056- Added the future_builtins module, which contains hex() and oct().
3057 These are the PEP 3127 version of these functions, designed to be
3058 compatible with the hex() and oct() builtins from Python 3.0. They
3059 differ slightly in their output formats from the existing, unchanged
3060 Python 2.6 builtins. The expected usage of the future_builtins
3061 module is:
3062 from future_builtins import hex, oct
3063
Eric Smith7ef40bf2008-02-20 23:34:22 +00003064- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3065 exponents for exponents with absolute value < 100. Follows C99
3066 standard. This is a change on Windows, which would use 3 digits.
3067 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3068 so that any alterations it does to the resulting string will be
3069 available in stringlib/formatter.h (for float.__format__).
3070
Eric Smith5a3c1352008-02-19 13:21:56 +00003071- Implemented PEP 3101, Advanced String Formatting. This adds a new
3072 builtin format(); a format() method for str and unicode; a
3073 __format__() method to object, str, unicode, int, long, float, and
3074 datetime; the class string.Formatter; and the C API
3075 PyObject_Format().
3076
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- Fixed several potential crashes, all caused by specially crafted
3078 __del__ methods exploiting objects in temporarily inconsistent
3079 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003080
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003081- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003082 prevent a possible crash: an Abstract Base Class would try to access
3083 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003084
Georg Brandl3ee81df2008-05-17 18:14:43 +00003085- Fixed repr() and str() of complex numbers with infinity or nan as
3086 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003087
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088- Clear all free lists during a gc.collect() of the highest generation
3089 in order to allow pymalloc to free more arenas. Python may give back
3090 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003091
Georg Brandl3ee81df2008-05-17 18:14:43 +00003092- Issue #2045: Fix an infinite recursion triggered when printing a
3093 subclass of collections.defaultdict, if its default_factory is set
3094 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003095
Christian Heimesf75dbef2008-02-08 00:11:31 +00003096- Fixed a minor memory leak in dictobject.c. The content of the free
3097 list was not freed on interpreter shutdown.
3098
Georg Brandl5a7eca12010-03-21 19:29:04 +00003099- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003100 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003101
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3103 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003104 to compact the internal free lists of pre-allocted ints and floats.
3105
Georg Brandl3ee81df2008-05-17 18:14:43 +00003106- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3107 calls. Python expected the return type int but the fork familie
3108 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003109
Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3111 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003112

3120 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003121
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122- Patch #1473257: generator objects gain a gi_code attribute. This is
3123 the same object as the func_code attribute of the function that
3124 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003125
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Issue #1920: "while 0" statements were completely removed by the
3127 compiler, even in the presence of an "else" clause, which is
3128 supposed to be run when the condition is false. Now the compiler
3129 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003130
Guido van Rossumeead05f2008-01-24 18:21:02 +00003131- A few crashers fixed: weakref_in_del.py (issue #1377858);
3132 loosing_dict_ref.py (issue #1303614, test67.py);
3133 borrowed_ref_[34].py (not in tracker).
3134
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003135- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003136 suppressed while an extension is loaded by calling SetErrorMode in
3137 dynload_win.c. The error is still reported properly.
3138
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003140 several extension methods and modules do not work without unicode
3141 support.
3142
Georg Brandl26543b12008-01-21 18:36:51 +00003143- Issue #1882: when compiling code from a string, encoding cookies in the
3144 second line of code were not always recognized correctly.
3145
Georg Brandl14404b62008-01-19 19:27:05 +00003146- Issue #1679: "0x" was taken as a valid integer literal.
3147
Georg Brandl6caad7d2008-01-26 14:19:22 +00003148- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003149 added.
3150
Christian Heimesc94e2b52008-01-14 04:13:37 +00003151- sys.float_info / PyFloat_GetInfo: The floating point information
3152 object was converted from a dict to a specialized structseq object.
3153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Patch #1816: Added sys.flags structseq. It exposes the status of
3155 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003156
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157- Objects/structseq.c: Implemented new structseq representation. The
3158 patch makes structseqs (e.g. the return value of os.stat) more
3159 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003183 and INF. float("nan"), float("inf") and float("-inf") now work on
3184 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003185
Georg Brandl3ee81df2008-05-17 18:14:43 +00003186- Compiler now generates simpler and faster code for dictionary
3187 literals. The oparg for BUILD_MAP now indicates an estimated
3188 dictionary size. There is a new opcode, STORE_MAP, for adding
3189 entries to the dictionary.

3219 file can now be directly executed by passing their name to the
3220 interpreter. The directory/zipfile is automatically inserted as the
3221 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003223- Issue #1265: Fix a problem with sys.settrace, if the tracing
3224 function uses a generator expression when at the same time the
3225 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003226
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003227- sets and frozensets now have an isdisjoint() method.
3228
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003229- optimize the performance of builtin.sum().
3230
Neal Norwitz44f326e2007-10-05 05:29:17 +00003231- Fix warnings found by the new version of the Coverity checker.
3232
Georg Brandl5a7eca12010-03-21 19:29:04 +00003233- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3235 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003236
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237- Issue #1686386: Tuple's tp_repr did not take into account the
3238 possibility of having a self-referential tuple, which is possible
3239 from C code. Nor did object's tp_str consider that a type's tp_str
3240 could do something that could lead to an inifinite recursion.
3241 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3242 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003243
Georg Brandl3ee81df2008-05-17 18:14:43 +00003244- Issue #1164: It was possible to trigger deadlock when using the
3245 'print' statement to write to a file since the GIL was not released
3246 as needed. Now PyObject_Print() does the right thing along with
3247 various tp_print implementations of the built-in types and those in
3248 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Issue #1147: Exceptions were directly allowing string exceptions in
3251 their throw() method even though string exceptions no longer
3252 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- Issue #1096: Prevent a segfault from getting the repr of a very
3255 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003256
Brett Cannon1e534b52007-09-07 04:18:30 +00003257- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258 PyObject_Call() never calling back out to Python code to trigger
3259 recursion depth updates/checks. Required the creation of a static
3260 RuntimeError instance in case normalizing an exception put the
3261 recursion check value past its limit. Fixes crashers
3262 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003263
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264- Patch #1031213: Decode source line in SyntaxErrors back to its

3268 with %G.
3269
Georg Brandl3ee81df2008-05-17 18:14:43 +00003270- Prevent expandtabs() on string and unicode objects from causing a
3271 segfault when a large width is passed on 32-bit platforms.

Georg Brandla5ea6892007-06-01 11:33:33 +00003276
Neal Norwitz0ac60192007-05-27 04:08:54 +00003277- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003278 __*__ attributes. (Some already existed, e.g., __doc__ and
3279 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003280
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003281- Add -3 option to the interpreter to warn about features that are
3282 deprecated and will be changed/removed in Python 3.0.
3283
Georg Brandl2134e752007-05-21 20:34:16 +00003284- Patch #1686487: you can now pass any mapping after '**' in function
3285 calls.
3286
Collin Winter62903052007-05-18 23:11:24 +00003287- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003288 "except E as target:". This is to provide forwards compatibility
3289 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003290
Brett Cannon229cee22007-05-05 01:34:02 +00003291- Deprecate BaseException.message as per PEP 352.
3292
Georg Brandl3ee81df2008-05-17 18:14:43 +00003293- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003294 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003295
Vinay Sajip8549ce32007-05-06 17:53:37 +00003296- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003297 setting a plain string, ie don't expand to single letter identifiers.
3298
Raymond Hettinger13936692007-04-11 18:40:58 +00003299- Request #1191699: Slices can now be pickled.
3300
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003301- Request #1193128: str.translate() now allows a None argument for
3302 translations that only remove characters without re-mapping the
3303 remaining characters.
3304
Georg Brandl5cb76c12007-03-21 09:00:39 +00003305- Patch #1682205: a TypeError while unpacking an iterable is no longer
3306 masked by a generic one with the message "unpack non-sequence".
3307
Neal Norwitzaa754b72007-03-21 06:39:48 +00003308- Remove unused file Python/fmod.c.
3309
Guido van Rossum143b5642007-03-23 04:58:42 +00003310- Bug #1683368: The object.__init__() and object.__new__() methods are
3311 now stricter in rejecting excess arguments. The only time when
3312 either allows excess arguments is when it is not overridden and the
3313 other one is. For backwards compatibility, when both are
3314 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003315 warning later). Also, type.__init__() insists on the same signature
3316 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003317
Georg Brandl3ee81df2008-05-17 18:14:43 +00003318- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3319 object to complex using its __complex__() method before falling back
3320 to the __float__() method. Therefore, the functions in the cmath
3321 module now can operate on objects that define a __complex__()
3322 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003323
Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Patch #1623563: allow __class__ assignment for classes with
3325 __slots__. The old and the new class are still required to have the
3326 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003327
Georg Brandl3ee81df2008-05-17 18:14:43 +00003328- Patch #1642547: Fix an error/crash when encountering syntax errors

3332 ``object.__reduce_ex__()`` is called with an object that is faking
3333 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003334
Georg Brandl3ee81df2008-05-17 18:14:43 +00003335- Patch #1680015: Don't modify __slots__ tuple if it contains an

3339
Georg Brandl7b9c5552007-03-12 14:30:05 +00003340- Bug #1678647: write a newline after printing an exception in any
3341 case, even when converting the value to a string failed.
3342
Georg Brandl871f1bc2007-03-12 13:17:36 +00003343- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003344 its argument, if it exists. If not, it will work like before. This
3345 allows customizing the output of dir() in the presence of a
3346 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003347
Collin Winter276887b2007-03-12 16:11:39 +00003348- Patch #922167: Python no longer segfaults when faced with infinitely
3349 self-recursive reload() calls (as reported by bug #742342).
3350
Georg Brandl3ee81df2008-05-17 18:14:43 +00003351- Patch #1675981: remove unreachable code from ``type.__new__()``
3352 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003354- Patch #1491866: change the complex() constructor to allow
3355 parthensized forms. This means complex(repr(x)) now works instead of
3356 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003357
Georg Brandlaa2321b2007-03-07 00:40:28 +00003358- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003359 makes the filenames the warning module prints much more sensible
3360 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003361
Georg Brandl49aafc92007-03-07 00:34:46 +00003362- Variant of patch #697613: don't exit the interpreter on a SystemExit
3363 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003364 variable is given, but break into the interactive interpreter just
3365 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003370- Bug #1674503: close the file opened by execfile() in an error
3371 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003372
Georg Brandl0fca97a2007-03-05 22:28:08 +00003373- Patch #1674228: when assigning a slice (old-style), check for the
3374 sq_ass_slice instead of the sq_slice slot.
3375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- When printing an unraisable error, don't print exceptions. before
3377 the name. This duplicates the behavior whening normally printing
3378 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003379
Georg Brandl3ee81df2008-05-17 18:14:43 +00003380- Bug #1653736: Properly discard third argument to

3387 created a weakref on itself during a __del__ call for new-style
3388 classes (classic classes still have the bug).

3435
Armin Rigo7ccbca92006-10-04 12:17:45 +00003436- A number of places, including integer negation and absolute value,

4006 -- the failure just occurred later, with a more cumbersome
4007 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004288- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4289 with RFC 3207 and forgets any knowledge obtained from the server not
4290 obtained from the TLS negotiation itself. Patch contributed by Bill
4291 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004292
Georg Brandl3ee81df2008-05-17 18:14:43 +00004293- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004294 that the SMTP.starttls() caller no longer needs to call ehlo()
4295 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004296 does not claim to support starttls. Adds the
4297 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4298 Fenner.

4378 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4379 silently miscode subclasses of those types. Now, it raises a
4380 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004381

Georg Brandl3ee81df2008-05-17 18:14:43 +00004396 time so that opening a database previously created with the DB_DUP
4397 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4398 opens. Specifically: dictionary assignment to a DB object will
4399 replace all values for a given key when the database allows
4400 duplicate values. DB users should use DB.put(k, v) when they want
4401 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004402

4408 characters with ASCII value less than 32. Also, it correctly quotes
4409 dots only if they occur on a single line, as opposed to the previous
4410 behavior of quoting dots if they are the second character of any
4411 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004412

Christian Heimes5b970ad2008-02-06 13:33:44 +00004740
Georg Brandl3ee81df2008-05-17 18:14:43 +00004741- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4742 to ``PyTuple_SetItem``, it can be used to populate a brand new

4755
Georg Brandl3ee81df2008-05-17 18:14:43 +00004756- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4757 of w# format code incorrectly truncated the length to an int, even
4758 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4759 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004760
Georg Brandl3ee81df2008-05-17 18:14:43 +00004761- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4781
4782- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4783 outside of pystate.c and should not be necessary.
4784
Georg Brandl3ee81df2008-05-17 18:14:43 +00004785- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4786 absolute imports. In earlier versions they might have used relative
4787 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004788
Georg Brandl3ee81df2008-05-17 18:14:43 +00004789- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4790 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004791
Georg Brandl3ee81df2008-05-17 18:14:43 +00004792- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004817- Removed the macfs module. It had been deprecated since Python 2.5.
4818 This lead to the deprecation of macostools.touched() as it relied
