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'.

Benjamin Peterson8d649632010-06-22 19:21:33 +000023- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
24
Antoine Pitrou4595e512010-06-11 21:48:02 +000025- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
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
36 too large.

46
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
Benjamin Peterson8a488082010-04-06 21:55:35 +000056- Issue #8329: Don't return the same lists from select.select when no fds are

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.

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>`_.

1553What's New in Python 2.6.1
1554==========================
1555
1556*Release date: 04-Dec-2008*
1557
1558Core and Builtins
1559-----------------
1560
1561- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1562 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1563 instead of throwing a MemoryError.
1564
1565- Issue #4367: Python would segfault during compiling when the unicodedata
1566 module couldn't be imported and \N escapes were present.
1567
1568- Issue #4348: Some bytearray methods returned that didn't cause any change to
1569 the bytearray, returned the same bytearray instead of a copy.
1570
1571- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1572
1573- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1574
1575- Issue #4048: The parser module now correctly validates relative imports.
1576
1577- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1578 exec statement.
1579
1580- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1581 method does not return iterators for the 4th and 5th items.
1582
1583- Issue #4209: Enabling unicode_literals and the print_function in the same
1584 __future__ import didn't work.
1585
1586- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1587 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1588 really executed because I cannot move to such directory on win2k)
1589
1590- Issue #4069: When set.remove(element) is used with a set element, the element
1591 is temporarily replaced with an equivalent frozenset. But the eventual
1592 KeyError would always report the empty frozenset([]) as the missing key. Now
1593 it correctly refers to the initial element.
1594
1595- Fixed C99 style comments in several files. Python is now C89 compatible
1596 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001743- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1744
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001745- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1746 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1747 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1748 ``printf`` function, whereas PyString_FromFormat has an independent
1749 implementation and uses "%zd" on all platforms for size_t values.
1750 This makes a difference on win64, where ``printf`` needs "%Id" to display
1751 64bit values.
1752
Benjamin Peterson97179b02008-09-09 20:55:01 +00001753- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1757 object; previously an int would be returned for small values. the __long__
1758 method is allowed to return either an int or a long, but the behaviour of
1759 float objects should not change to respect backward compatibility.
1760
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001761- Issue #3751: str.rpartition would perform a left-partition when called with
1762 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001768 was correctly parsed but parsing of subsequent arguments failed.
1769
Vinay Sajip35e3b032008-09-01 14:33:59 +00001770- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001771 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1772 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1773 when given a tuple of classes as second argument, were looking up
1774 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1775 type object.
1776
Neal Norwitz18aa3882008-08-24 05:04:52 +00001777- Fix crashes on memory allocation failure found with failmalloc.
1778
1779- Fix memory leaks found with valgrind and update suppressions file.
1780
1781- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1782
1783- Fix problem using wrong name in decimal module reported by pychecker.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001911What's New in Python 2.6 beta 3?
1912================================
1913
Barry Warsaw07a4a382008-08-21 01:15:08 +00001914*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001915
1916Core and Builtins
1917-----------------
1918
Guido van Rossumf8402962008-08-20 15:01:50 +00001919- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1920 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1921 extensions do not automatically benefit from the class attribute
1922 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1923 to their tp_flags field if they care. This is a backwards
1924 compatibility feature; in 3.0, all types will use the cache by
1925 default.
1926
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001927- Keyword arguments can now follow starred arguments. (``f(a, *args,
1928 keyword=23)`` is now valid syntax.)
1929
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001930- ctypes function pointers that are COM methods have a boolean True
1931 value again.
1932
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001933- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1934 by denying s# to parse objects that have a releasebuffer procedure,
1935 and introducing s*.
1936
Georg Brandl1e13ea92008-08-11 09:07:59 +00001937- Issue #3537: Fix an assertion failure when an empty but presized dict
1938 object was stored in the freelist.
1939
Mark Dickinsonb6467572008-08-04 21:30:09 +00001940- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1941 ValueError consistently across platforms.
1942
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001943- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1944 (64bit Unix, for example), unichr() would truncate its argument and return
1945 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1946
Neal Norwitze7d8be82008-07-31 17:17:14 +00001947- Apply security patches from Apple.
1948
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001949- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1950 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1951
Antoine Pitrou92f82162008-07-25 22:22:08 +00001952- Issue #1819: function calls with several named parameters are now on
1953 average 35% faster (as measured by pybench).
1954
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001955- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1956 the python debugger steps into a class statement: the free variables (local
1957 variables defined in an outer scope) would be deleted from the outer scope.
1958
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001959- Issue #2620: Overflow checking when allocating or reallocating memory
1960 was not always being done properly in some python types and extension
1961 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1962 all been updated to perform better checks and places in the code that
1963 would previously leak memory on the error path when such an allocation
1964 failed have been fixed.
1965

1967-------
1968
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001969- Issue #3612: Added some missing basic types in ctypes.wintypes.
1970
Benjamin Petersone977ad42008-08-20 01:42:01 +00001971- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1972 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1973
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001974- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1975 version reported by these tools does not necessarily follow the python
1976 version numbering scheme, so the module is less strict when parsing it.
1977
Nick Coghlanf70385a2008-08-18 12:42:46 +00001978- Issue #2235: Added Py3k warnings for types which will become unhashable
1979 under the stricter __hash__ inheritance rules in 3.0. Several types
1980 which did not meet the rules for hash invariants and were already
1981 unhashable in 3.0 have now been explicitly flagged as unhashable in
1982 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1983 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1984
Brett Cannon88f801d2008-08-18 00:46:22 +00001985- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1986 imported into the module but exposed as part of the module's API.
1987
Brett Cannon7b96f072008-08-18 00:41:11 +00001988- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1989
Brett Cannon46225e72008-08-18 00:36:52 +00001990- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1991
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001992- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1993
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001994- Issue #3575: Incremental decoder's decode function now takes bytearray
1995 by using 's*' instead of 't#'.
1996
Jesus Cea585ad8a2009-07-02 15:37:21 +00001997- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001998 fails unicode conversion on 2nd parameter. (windows only)
1999
Facundo Batista94f243a2008-08-17 03:38:39 +00002000- Issue 2464. urllib2 now supports a malformation in the URL received
2001 in a redirect.
2002
Brett Cannonabe423e2008-08-16 21:47:07 +00002003- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002004 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002005
Facundo Batistaeb90b782008-08-16 14:44:07 +00002006- Issue #2776: fixed small issue when handling an URL with double slash
2007 after a 302 response in the case of not going through a proxy.
2008
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002009- Issue #2676: in the email package, content-type parsing was hanging on
2010 pathological input because of quadratic or exponential behaviour of a
2011 regular expression.
2012
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002013- Issue #3476: binary buffered reading through the new "io" library is now
2014 thread-safe.
2015
Brett Cannonbf3157b2008-08-14 05:00:03 +00002016- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2017 since mimetools itself is deprecated. Because modules are cached, all
2018 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2019
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002020- Issue #3134: shutil referenced undefined WindowsError symbol.
2021
Robert Schuppenies14646332008-08-10 11:01:53 +00002022- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2023 menu entries were not deleted.
2024
Brett Cannon83e81842008-08-09 23:30:55 +00002025- Copied the implementation of reduce() to _functools.reduce() to have a
2026 version that did not raise a DeprecationWarning under -3.
2027
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002028- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2029 a MemoryError rather than silently stop the iteration.
2030
Guido van Rossum59ce9012008-08-09 14:55:34 +00002031- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2032 to _sre.compile() will now be rejected. This should not affect anybody
2033 since the re.compile() function never generates invalid re-bytecode.
2034
Skip Montanaroa032bf42008-08-08 22:52:51 +00002035- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2036 upon first access it can be automatically initialized from the csv file if
2037 it wasn't initialized during instantiation.
2038
Brett Cannon3aa2a492008-08-06 22:28:09 +00002039- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2040 the reload() built-in has been removed.
2041
Brett Cannon7e30b672008-08-04 21:52:25 +00002042- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002043 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002050- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2051 raised an AttributeError.
2052
Benjamin Peterson01a24322008-07-28 23:35:27 +00002053- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002054 asking for a specific length. This problem only affected files opened
2055 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002056
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002057- Issue #3449: Update decimal module to use most recent specification
2058 (v. 1.68) and tests (v. 2.58) from IBM.
2059
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002060- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2068
2069- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2070 invalid arguments.
2071
2072- Issue #3302: Fix several crashes when calling locale's gettext functions
2073 with None arguments.

2075- Issue #3389: Allow resolving dotted names for handlers in logging
2076 configuration files.
2077
2078- Deprecate the sunaudio module for removal in Python 3.0.
2079
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002080- Issue #3394: zipfile.writestr sets external attributes when passed a
2081 file name rather than a ZipInfo instance, so files are extracted with
2082 mode 0600 rather than 000 under Unix.
2083
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002084- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2097 interaction with the tp_hash slot (added in 2.6b2) are now documented
2098
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002099- Issue #643841: The language reference now provides more detailed
2100 coverage of the lookup process for special methods. The disclaimers
2101 regarding lack of coverage of new-style classes have also been
2102 removed, since the coverage is now fairly reasonable.

2111-----------------
2112
Georg Brandl3e483f62008-07-16 22:57:41 +00002113- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2114 its methods now allow for items objects that can be converted to
2115 an integer using operator.index().
2116
Mark Dickinson64b7e502008-07-16 09:40:03 +00002117- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2118 produced a ValueError instead of giving the correct float.
2119
Eric Smitha5fa5a22008-07-16 00:11:49 +00002120- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2121 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2122
Mark Dickinson7103aa42008-07-15 19:08:33 +00002123- Issue #3008: the float type has a new instance method 'float.hex'
2124 and a new class method 'float.fromhex' to convert floating-point
2125 numbers to and from hexadecimal strings, respectively.
2126
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002127- Issue #2235: __hash__ is once again inherited by default. To allow
2128 collections.Hashable to remain meaningful in the presence of the
2129 default hash implementation (object.__hash__), it is now possible
2130 to explicit block inheritance of hash by setting __hash__=None at
2131 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2132 level.
2133
Nick Coghlanb028f502008-07-13 14:52:36 +00002134- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2135 the parent module cannot be found while performing an absolute import.
2136 This means that an incorrectly defined __package__ attribute will
2137 now only prevent relative imports in that module rather than causing
2138 all imports from that module to fail.
2139
Nick Coghlan14ff9942008-07-08 14:21:42 +00002140- Issue #2517: Allow unicode messages in Exceptions again by correctly

2150 another thread's dictionary.
2151
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002152- Issue #3004: Minor change to slice.indices(): the start and stop
2153 arguments are now treated identically, making the behaviour easier
2154 to describe and understand. For example, slice(None, -10,
2155 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2156 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2157 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00002159- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00002611 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002612
2613 This is controlled by the configure argument ``--with-universal-archs``:
2614
2615 - ``--with-universal-archs=all``: install 4-way universal
2616
2617 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2618
2619 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2620

2660 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Issue #1631171: Re-implement the 'warnings' module in C (the
2674 original Python code has been kept as backup). This will allow for
2675 using the 'warning's machinery in such places as the parser where
2676 use of pure Python code is not possible. Both the ``showarning()``
2677 and ``formatwarning()`` gain an optional 'line' argument which is
2678 not called by default for backwards-compatibility reasons. Setting
2679 ``warnings.showwarning()`` to an implementation that lacks support
2680 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002705- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00002743- Issue #2550: The approach used by client/server code for obtaining
2744 ports to listen on in network-oriented tests has been refined in an
2745 effort to facilitate running multiple instances of the entire
2746 regression test suite in parallel without issue.
2747 test_support.bind_port() has been fixed such that it will always
2748 return a unique port -- which wasn't always the case with the
2749 previous implementation, especially if socket options had been set
2750 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2751 new implementation of bind_port() will actually raise an exception
2752 if it is passed an AF_INET/SOCK_STREAM socket with either the
2753 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2754 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2755 the socket it's been passed. This currently only applies to
2756 Windows. This option prevents any other sockets from binding to the
2757 host/port we've bound to, thus removing the possibility of the
2758 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2759 when a second SOCK_STREAM socket binds and accepts to a host/port
2760 that's already been bound by another socket. The optional preferred
2761 port parameter to bind_port() has been removed. Under no
2762 circumstances should tests be hard coding ports!
2763
2764 test_support.find_unused_port() has also been introduced, which will
2765 pass a temporary socket object to bind_port() in order to obtain an
2766 unused port. The temporary socket object is then closed and
2767 deleted, and the port is returned. This method should only be used
2768 for obtaining an unused port in order to pass to an external program
2769 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2770 a parameter to a server-oriented class that doesn't give you direct
2771 access to the underlying socket used.
2772
2773 Finally, test_support.HOST has been introduced, which should be used
2774 for the host argument of any relevant socket calls (i.e. bind and
2775 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002776
2777 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002778 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002779 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2780 test_asynchat and test_socket_ssl.
2781
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782 It is now possible for multiple instances of the regression test
2783 suite to run in parallel without issue.

2985 from 't' to '?'.
2986
Thomas Heller78b8f442008-03-05 14:53:39 +00002987- The bundled libffi copy is now in sync with the recently released
2988 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002989 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2990 files are used. On all linux systems the --with-system-ffi
2991 configure option defaults to "yes".

3051
Fred Drakea8ee94b2008-03-01 02:45:07 +00003052- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003053 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003054
Georg Brandlad61bc82008-02-23 15:11:18 +00003055- Issue #2067: file.__exit__() now calls subclasses' close() method.
3056
3057- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003058
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003059- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003060 issue 215555 for a discussion.
3061
Eric Smitha73fbe72008-02-23 03:09:44 +00003062- Added the future_builtins module, which contains hex() and oct().
3063 These are the PEP 3127 version of these functions, designed to be
3064 compatible with the hex() and oct() builtins from Python 3.0. They
3065 differ slightly in their output formats from the existing, unchanged
3066 Python 2.6 builtins. The expected usage of the future_builtins
3067 module is:
3068 from future_builtins import hex, oct
3069
Eric Smith7ef40bf2008-02-20 23:34:22 +00003070- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3071 exponents for exponents with absolute value < 100. Follows C99
3072 standard. This is a change on Windows, which would use 3 digits.
3073 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3074 so that any alterations it does to the resulting string will be
3075 available in stringlib/formatter.h (for float.__format__).
3076
Eric Smith5a3c1352008-02-19 13:21:56 +00003077- Implemented PEP 3101, Advanced String Formatting. This adds a new
3078 builtin format(); a format() method for str and unicode; a
3079 __format__() method to object, str, unicode, int, long, float, and
3080 datetime; the class string.Formatter; and the C API
3081 PyObject_Format().
3082
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083- Fixed several potential crashes, all caused by specially crafted
3084 __del__ methods exploiting objects in temporarily inconsistent
3085 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003086
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003087- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088 prevent a possible crash: an Abstract Base Class would try to access
3089 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003090
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091- Fixed repr() and str() of complex numbers with infinity or nan as
3092 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003093
Georg Brandl3ee81df2008-05-17 18:14:43 +00003094- Clear all free lists during a gc.collect() of the highest generation
3095 in order to allow pymalloc to free more arenas. Python may give back
3096 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003097
Georg Brandl3ee81df2008-05-17 18:14:43 +00003098- Issue #2045: Fix an infinite recursion triggered when printing a
3099 subclass of collections.defaultdict, if its default_factory is set
3100 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003101
Christian Heimesf75dbef2008-02-08 00:11:31 +00003102- Fixed a minor memory leak in dictobject.c. The content of the free
3103 list was not freed on interpreter shutdown.
3104
Georg Brandl5a7eca12010-03-21 19:29:04 +00003105- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003106 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003107
Georg Brandl3ee81df2008-05-17 18:14:43 +00003108- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3109 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003110 to compact the internal free lists of pre-allocted ints and floats.
3111
Georg Brandl3ee81df2008-05-17 18:14:43 +00003112- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3113 calls. Python expected the return type int but the fork familie
3114 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003115
Georg Brandl3ee81df2008-05-17 18:14:43 +00003116- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3117 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003118

Georg Brandl3ee81df2008-05-17 18:14:43 +00003125- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3126 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003127
Georg Brandl3ee81df2008-05-17 18:14:43 +00003128- Patch #1473257: generator objects gain a gi_code attribute. This is
3129 the same object as the func_code attribute of the function that
3130 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003131
Georg Brandl3ee81df2008-05-17 18:14:43 +00003132- Issue #1920: "while 0" statements were completely removed by the
3133 compiler, even in the presence of an "else" clause, which is
3134 supposed to be run when the condition is false. Now the compiler
3135 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003136
Guido van Rossumeead05f2008-01-24 18:21:02 +00003137- A few crashers fixed: weakref_in_del.py (issue #1377858);
3138 loosing_dict_ref.py (issue #1303614, test67.py);
3139 borrowed_ref_[34].py (not in tracker).
3140
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003141- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003142 suppressed while an extension is loaded by calling SetErrorMode in
3143 dynload_win.c. The error is still reported properly.
3144
Georg Brandl3ee81df2008-05-17 18:14:43 +00003145- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003146 several extension methods and modules do not work without unicode
3147 support.
3148
Georg Brandl26543b12008-01-21 18:36:51 +00003149- Issue #1882: when compiling code from a string, encoding cookies in the
3150 second line of code were not always recognized correctly.
3151
Georg Brandl14404b62008-01-19 19:27:05 +00003152- Issue #1679: "0x" was taken as a valid integer literal.
3153
Georg Brandl6caad7d2008-01-26 14:19:22 +00003154- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003155 added.
3156
Christian Heimesc94e2b52008-01-14 04:13:37 +00003157- sys.float_info / PyFloat_GetInfo: The floating point information
3158 object was converted from a dict to a specialized structseq object.
3159
Georg Brandl3ee81df2008-05-17 18:14:43 +00003160- Patch #1816: Added sys.flags structseq. It exposes the status of
3161 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003162
Georg Brandl3ee81df2008-05-17 18:14:43 +00003163- Objects/structseq.c: Implemented new structseq representation. The
3164 patch makes structseqs (e.g. the return value of os.stat) more
3165 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003166
Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003189 and INF. float("nan"), float("inf") and float("-inf") now work on
3190 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003191
Georg Brandl3ee81df2008-05-17 18:14:43 +00003192- Compiler now generates simpler and faster code for dictionary
3193 literals. The oparg for BUILD_MAP now indicates an estimated
3194 dictionary size. There is a new opcode, STORE_MAP, for adding
3195 entries to the dictionary.

3225 file can now be directly executed by passing their name to the
3226 interpreter. The directory/zipfile is automatically inserted as the
3227 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003229- Issue #1265: Fix a problem with sys.settrace, if the tracing
3230 function uses a generator expression when at the same time the
3231 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003232
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003233- sets and frozensets now have an isdisjoint() method.
3234
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003235- optimize the performance of builtin.sum().
3236
Neal Norwitz44f326e2007-10-05 05:29:17 +00003237- Fix warnings found by the new version of the Coverity checker.
3238
Georg Brandl5a7eca12010-03-21 19:29:04 +00003239- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003240 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3241 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- Issue #1686386: Tuple's tp_repr did not take into account the
3244 possibility of having a self-referential tuple, which is possible
3245 from C code. Nor did object's tp_str consider that a type's tp_str
3246 could do something that could lead to an inifinite recursion.
3247 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3248 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Issue #1164: It was possible to trigger deadlock when using the
3251 'print' statement to write to a file since the GIL was not released
3252 as needed. Now PyObject_Print() does the right thing along with
3253 various tp_print implementations of the built-in types and those in
3254 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003255
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256- Issue #1147: Exceptions were directly allowing string exceptions in
3257 their throw() method even though string exceptions no longer
3258 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003259
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260- Issue #1096: Prevent a segfault from getting the repr of a very
3261 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003262
Brett Cannon1e534b52007-09-07 04:18:30 +00003263- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264 PyObject_Call() never calling back out to Python code to trigger
3265 recursion depth updates/checks. Required the creation of a static
3266 RuntimeError instance in case normalizing an exception put the
3267 recursion check value past its limit. Fixes crashers
3268 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003269
Georg Brandl3ee81df2008-05-17 18:14:43 +00003270- Patch #1031213: Decode source line in SyntaxErrors back to its

3274 with %G.
3275
Georg Brandl3ee81df2008-05-17 18:14:43 +00003276- Prevent expandtabs() on string and unicode objects from causing a
3277 segfault when a large width is passed on 32-bit platforms.

Georg Brandla5ea6892007-06-01 11:33:33 +00003282
Neal Norwitz0ac60192007-05-27 04:08:54 +00003283- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284 __*__ attributes. (Some already existed, e.g., __doc__ and
3285 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003286
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003287- Add -3 option to the interpreter to warn about features that are
3288 deprecated and will be changed/removed in Python 3.0.
3289
Georg Brandl2134e752007-05-21 20:34:16 +00003290- Patch #1686487: you can now pass any mapping after '**' in function
3291 calls.
3292
Collin Winter62903052007-05-18 23:11:24 +00003293- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003294 "except E as target:". This is to provide forwards compatibility
3295 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003296
Brett Cannon229cee22007-05-05 01:34:02 +00003297- Deprecate BaseException.message as per PEP 352.
3298
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003300 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003301
Vinay Sajip8549ce32007-05-06 17:53:37 +00003302- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003303 setting a plain string, ie don't expand to single letter identifiers.
3304
Raymond Hettinger13936692007-04-11 18:40:58 +00003305- Request #1191699: Slices can now be pickled.
3306
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003307- Request #1193128: str.translate() now allows a None argument for
3308 translations that only remove characters without re-mapping the
3309 remaining characters.
3310
Georg Brandl5cb76c12007-03-21 09:00:39 +00003311- Patch #1682205: a TypeError while unpacking an iterable is no longer
3312 masked by a generic one with the message "unpack non-sequence".
3313
Neal Norwitzaa754b72007-03-21 06:39:48 +00003314- Remove unused file Python/fmod.c.
3315
Guido van Rossum143b5642007-03-23 04:58:42 +00003316- Bug #1683368: The object.__init__() and object.__new__() methods are
3317 now stricter in rejecting excess arguments. The only time when
3318 either allows excess arguments is when it is not overridden and the
3319 other one is. For backwards compatibility, when both are
3320 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003321 warning later). Also, type.__init__() insists on the same signature
3322 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003323
Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3325 object to complex using its __complex__() method before falling back
3326 to the __float__() method. Therefore, the functions in the cmath
3327 module now can operate on objects that define a __complex__()
3328 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003329
Georg Brandl3ee81df2008-05-17 18:14:43 +00003330- Patch #1623563: allow __class__ assignment for classes with
3331 __slots__. The old and the new class are still required to have the
3332 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003333
Georg Brandl3ee81df2008-05-17 18:14:43 +00003334- Patch #1642547: Fix an error/crash when encountering syntax errors

3338 ``object.__reduce_ex__()`` is called with an object that is faking
3339 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003340
Georg Brandl3ee81df2008-05-17 18:14:43 +00003341- Patch #1680015: Don't modify __slots__ tuple if it contains an

3345
Georg Brandl7b9c5552007-03-12 14:30:05 +00003346- Bug #1678647: write a newline after printing an exception in any
3347 case, even when converting the value to a string failed.
3348
Georg Brandl871f1bc2007-03-12 13:17:36 +00003349- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003350 its argument, if it exists. If not, it will work like before. This
3351 allows customizing the output of dir() in the presence of a
3352 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003353
Collin Winter276887b2007-03-12 16:11:39 +00003354- Patch #922167: Python no longer segfaults when faced with infinitely
3355 self-recursive reload() calls (as reported by bug #742342).
3356
Georg Brandl3ee81df2008-05-17 18:14:43 +00003357- Patch #1675981: remove unreachable code from ``type.__new__()``
3358 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003360- Patch #1491866: change the complex() constructor to allow
3361 parthensized forms. This means complex(repr(x)) now works instead of
3362 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003363
Georg Brandlaa2321b2007-03-07 00:40:28 +00003364- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365 makes the filenames the warning module prints much more sensible
3366 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003367
Georg Brandl49aafc92007-03-07 00:34:46 +00003368- Variant of patch #697613: don't exit the interpreter on a SystemExit
3369 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003370 variable is given, but break into the interactive interpreter just
3371 like on other exceptions or normal program exit.

3377 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003378
Georg Brandl0fca97a2007-03-05 22:28:08 +00003379- Patch #1674228: when assigning a slice (old-style), check for the
3380 sq_ass_slice instead of the sq_slice slot.
3381
Georg Brandl3ee81df2008-05-17 18:14:43 +00003382- When printing an unraisable error, don't print exceptions. before
3383 the name. This duplicates the behavior whening normally printing
3384 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003385
Georg Brandl3ee81df2008-05-17 18:14:43 +00003386- Bug #1653736: Properly discard third argument to

3393 created a weakref on itself during a __del__ call for new-style
3394 classes (classic classes still have the bug).

3441
Armin Rigo7ccbca92006-10-04 12:17:45 +00003442- A number of places, including integer negation and absolute value,

4013 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004294- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4295 with RFC 3207 and forgets any knowledge obtained from the server not
4296 obtained from the TLS negotiation itself. Patch contributed by Bill
4297 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004298
Georg Brandl3ee81df2008-05-17 18:14:43 +00004299- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004300 that the SMTP.starttls() caller no longer needs to call ehlo()
4301 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004302 does not claim to support starttls. Adds the
4303 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4304 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004358- itertools.chain() now has an alternate constructor,

4384 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4385 silently miscode subclasses of those types. Now, it raises a
4386 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004387

Georg Brandl3ee81df2008-05-17 18:14:43 +00004402 time so that opening a database previously created with the DB_DUP
4403 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4404 opens. Specifically: dictionary assignment to a DB object will
4405 replace all values for a given key when the database allows
4406 duplicate values. DB users should use DB.put(k, v) when they want
4407 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004408

4414 characters with ASCII value less than 32. Also, it correctly quotes
4415 dots only if they occur on a single line, as opposed to the previous
4416 behavior of quoting dots if they are the second character of any
4417 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004418

4740-----
4741
Georg Brandl3ee81df2008-05-17 18:14:43 +00004742- Unified naming convention for free lists and their limits. All free
4743 lists in Object/ are named ``free_list``, the counter ``numfree``

4745 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004746
Georg Brandl3ee81df2008-05-17 18:14:43 +00004747- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4748 to ``PyTuple_SetItem``, it can be used to populate a brand new

4761
Georg Brandl3ee81df2008-05-17 18:14:43 +00004762- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4763 of w# format code incorrectly truncated the length to an int, even
4764 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4765 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004766
Georg Brandl3ee81df2008-05-17 18:14:43 +00004767- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4785- Fix some leftovers from the conversion from int to Py_ssize_t
4786 (relevant to strings and sequences of more than 2**31 items).
4787
4788- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4789 outside of pystate.c and should not be necessary.
4790
Georg Brandl3ee81df2008-05-17 18:14:43 +00004791- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4792 absolute imports. In earlier versions they might have used relative
4793 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004794
Georg Brandl3ee81df2008-05-17 18:14:43 +00004795- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4796 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004797
Georg Brandl3ee81df2008-05-17 18:14:43 +00004798- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4808 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004809

Georg Brandl3ee81df2008-05-17 18:14:43 +00004823- Removed the macfs module. It had been deprecated since Python 2.5.
4824 This lead to the deprecation of macostools.touched() as it relied
4825 solely on macfs and was a no-op under OS X.
