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'.

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

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

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.

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>`_.

1558What's New in Python 2.6.1
1559==========================
1560
1561*Release date: 04-Dec-2008*
1562
1563Core and Builtins
1564-----------------
1565
1566- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1567 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1568 instead of throwing a MemoryError.
1569
1570- Issue #4367: Python would segfault during compiling when the unicodedata
1571 module couldn't be imported and \N escapes were present.
1572
1573- Issue #4348: Some bytearray methods returned that didn't cause any change to
1574 the bytearray, returned the same bytearray instead of a copy.
1575
1576- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1577
1578- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1579
1580- Issue #4048: The parser module now correctly validates relative imports.
1581
1582- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1583 exec statement.
1584
1585- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1586 method does not return iterators for the 4th and 5th items.
1587
1588- Issue #4209: Enabling unicode_literals and the print_function in the same
1589 __future__ import didn't work.
1590
1591- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1592 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1593 really executed because I cannot move to such directory on win2k)
1594
1595- Issue #4069: When set.remove(element) is used with a set element, the element
1596 is temporarily replaced with an equivalent frozenset. But the eventual
1597 KeyError would always report the empty frozenset([]) as the missing key. Now
1598 it correctly refers to the initial element.
1599
1600- Fixed C99 style comments in several files. Python is now C89 compatible
1601 again.

1749
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001750- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1751 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1752 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1753 ``printf`` function, whereas PyString_FromFormat has an independent
1754 implementation and uses "%zd" on all platforms for size_t values.
1755 This makes a difference on win64, where ``printf`` needs "%Id" to display
1756 64bit values.
1757
Benjamin Peterson97179b02008-09-09 20:55:01 +00001758- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1762 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001766- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001775- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001776 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1777 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1778 when given a tuple of classes as second argument, were looking up
1779 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1780 type object.

1873-----------------
1874
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001875- Issue #2975: When compiling several extension modules with Visual Studio 2008
1876 from the same python interpreter, some environment variables would grow
1877 without limit.
1878
Benjamin Peterson37346b22008-08-23 20:27:43 +00001879- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1880 exploitation of poor argument checking.
1881
Gerhard Häringef2276b2008-09-12 13:54:06 +00001882- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1883
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00001884- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
1885 remaining ones have "pysqlite_" prefix.
1886
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001887- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1893
Nick Coghland2e09382008-09-11 12:11:06 +00001894- Issue #3781: Add test.test_support.check_warnings() as a convenience
1895 wrapper for warnings.catch_warnings() that makes it easier to check
1896 that expected warning messages are being reported.
1897
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001898- Issue #3796: Some tests functions were not enabled in test_float.
1899

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001916What's New in Python 2.6 beta 3?
1917================================
1918
Barry Warsaw07a4a382008-08-21 01:15:08 +00001919*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001920
1921Core and Builtins
1922-----------------
1923
Guido van Rossumf8402962008-08-20 15:01:50 +00001924- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1925 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1926 extensions do not automatically benefit from the class attribute
1927 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1928 to their tp_flags field if they care. This is a backwards
1929 compatibility feature; in 3.0, all types will use the cache by
1930 default.
1931
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001932- Keyword arguments can now follow starred arguments. (``f(a, *args,
1933 keyword=23)`` is now valid syntax.)
1934
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001935- ctypes function pointers that are COM methods have a boolean True
1936 value again.
1937
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001938- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1939 by denying s# to parse objects that have a releasebuffer procedure,
1940 and introducing s*.
1941
Georg Brandl1e13ea92008-08-11 09:07:59 +00001942- Issue #3537: Fix an assertion failure when an empty but presized dict
1943 object was stored in the freelist.
1944
Mark Dickinsonb6467572008-08-04 21:30:09 +00001945- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1946 ValueError consistently across platforms.
1947
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001948- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1949 (64bit Unix, for example), unichr() would truncate its argument and return
1950 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1951
Neal Norwitze7d8be82008-07-31 17:17:14 +00001952- Apply security patches from Apple.
1953
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001954- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1955 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1956
Antoine Pitrou92f82162008-07-25 22:22:08 +00001957- Issue #1819: function calls with several named parameters are now on
1958 average 35% faster (as measured by pybench).
1959
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001960- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1961 the python debugger steps into a class statement: the free variables (local
1962 variables defined in an outer scope) would be deleted from the outer scope.
1963
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001964- Issue #2620: Overflow checking when allocating or reallocating memory
1965 was not always being done properly in some python types and extension
1966 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1967 all been updated to perform better checks and places in the code that
1968 would previously leak memory on the error path when such an allocation
1969 failed have been fixed.
1970
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001971Library
1972-------
1973
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001974- Issue #3612: Added some missing basic types in ctypes.wintypes.
1975
Benjamin Petersone977ad42008-08-20 01:42:01 +00001976- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1977 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1978
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001979- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1980 version reported by these tools does not necessarily follow the python
1981 version numbering scheme, so the module is less strict when parsing it.
1982
Nick Coghlanf70385a2008-08-18 12:42:46 +00001983- Issue #2235: Added Py3k warnings for types which will become unhashable
1984 under the stricter __hash__ inheritance rules in 3.0. Several types
1985 which did not meet the rules for hash invariants and were already
1986 unhashable in 3.0 have now been explicitly flagged as unhashable in
1987 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1988 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1989
Brett Cannon88f801d2008-08-18 00:46:22 +00001990- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1991 imported into the module but exposed as part of the module's API.
1992
Brett Cannon7b96f072008-08-18 00:41:11 +00001993- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1994
Brett Cannon46225e72008-08-18 00:36:52 +00001995- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1996
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001997- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1998
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001999- Issue #3575: Incremental decoder's decode function now takes bytearray
2000 by using 's*' instead of 't#'.
2001
Jesus Cea585ad8a2009-07-02 15:37:21 +00002002- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002003 fails unicode conversion on 2nd parameter. (windows only)
2004
Facundo Batista94f243a2008-08-17 03:38:39 +00002005- Issue 2464. urllib2 now supports a malformation in the URL received
2006 in a redirect.
2007
Brett Cannonabe423e2008-08-16 21:47:07 +00002008- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002009 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002010
Facundo Batistaeb90b782008-08-16 14:44:07 +00002011- Issue #2776: fixed small issue when handling an URL with double slash
2012 after a 302 response in the case of not going through a proxy.
2013
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002014- Issue #2676: in the email package, content-type parsing was hanging on
2015 pathological input because of quadratic or exponential behaviour of a
2016 regular expression.
2017
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002018- Issue #3476: binary buffered reading through the new "io" library is now
2019 thread-safe.
2020
Brett Cannonbf3157b2008-08-14 05:00:03 +00002021- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2022 since mimetools itself is deprecated. Because modules are cached, all
2023 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2024
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002025- Issue #3134: shutil referenced undefined WindowsError symbol.
2026
Robert Schuppenies14646332008-08-10 11:01:53 +00002027- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2028 menu entries were not deleted.
2029
Brett Cannon83e81842008-08-09 23:30:55 +00002030- Copied the implementation of reduce() to _functools.reduce() to have a
2031 version that did not raise a DeprecationWarning under -3.
2032
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002033- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2034 a MemoryError rather than silently stop the iteration.
2035
Guido van Rossum59ce9012008-08-09 14:55:34 +00002036- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2037 to _sre.compile() will now be rejected. This should not affect anybody
2038 since the re.compile() function never generates invalid re-bytecode.
2039
Skip Montanaroa032bf42008-08-08 22:52:51 +00002040- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2041 upon first access it can be automatically initialized from the csv file if
2042 it wasn't initialized during instantiation.
2043
Brett Cannon3aa2a492008-08-06 22:28:09 +00002044- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2045 the reload() built-in has been removed.
2046
Brett Cannon7e30b672008-08-04 21:52:25 +00002047- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002048 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2052 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2053 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002054
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002055- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2056 raised an AttributeError.
2057
Benjamin Peterson01a24322008-07-28 23:35:27 +00002058- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002059 asking for a specific length. This problem only affected files opened
2060 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002061
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002062- Issue #3449: Update decimal module to use most recent specification
2063 (v. 1.68) and tests (v. 2.58) from IBM.
2064
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002065- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2073
2074- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2075 invalid arguments.
2076
2077- Issue #3302: Fix several crashes when calling locale's gettext functions
2078 with None arguments.
2079
2080- Issue #3389: Allow resolving dotted names for handlers in logging
2081 configuration files.
2082
2083- Deprecate the sunaudio module for removal in Python 3.0.
2084
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002085- Issue #3394: zipfile.writestr sets external attributes when passed a
2086 file name rather than a ZipInfo instance, so files are extracted with
2087 mode 0600 rather than 000 under Unix.
2088
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002089- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2090 argument in python 2.5, this broke code that subclassed Popen to include its
2091 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2099-------------
2100
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002101- Issue #2235: the C API function PyObject_HashNotImplemented and its
2102 interaction with the tp_hash slot (added in 2.6b2) are now documented
2103
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002104- Issue #643841: The language reference now provides more detailed
2105 coverage of the lookup process for special methods. The disclaimers
2106 regarding lack of coverage of new-style classes have also been
2107 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002110What's New in Python 2.6 beta 2?
2111================================
2112
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002113*Release date: 17-Jul-2008*
2114
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002115Core and Builtins
2116-----------------
2117
Georg Brandl3e483f62008-07-16 22:57:41 +00002118- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2119 its methods now allow for items objects that can be converted to
2120 an integer using operator.index().
2121
Mark Dickinson64b7e502008-07-16 09:40:03 +00002122- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2123 produced a ValueError instead of giving the correct float.
2124
Eric Smitha5fa5a22008-07-16 00:11:49 +00002125- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2126 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2127
Mark Dickinson7103aa42008-07-15 19:08:33 +00002128- Issue #3008: the float type has a new instance method 'float.hex'
2129 and a new class method 'float.fromhex' to convert floating-point
2130 numbers to and from hexadecimal strings, respectively.
2131
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002132- Issue #2235: __hash__ is once again inherited by default. To allow
2133 collections.Hashable to remain meaningful in the presence of the
2134 default hash implementation (object.__hash__), it is now possible
2135 to explicit block inheritance of hash by setting __hash__=None at
2136 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2137 level.
2138
Nick Coghlanb028f502008-07-13 14:52:36 +00002139- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2140 the parent module cannot be found while performing an absolute import.
2141 This means that an incorrectly defined __package__ attribute will
2142 now only prevent relative imports in that module rather than causing
2143 all imports from that module to fail.
2144
Nick Coghlan14ff9942008-07-08 14:21:42 +00002145- Issue #2517: Allow unicode messages in Exceptions again by correctly
2146 bypassing the instance dictionary when looking up __unicode__ on
2147 new-style classes.
2148
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002149- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2150 set to a custom object whose write() method happens to install
2151 another file in sys.stdout.
2152
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002153- Issue #3088: Corrected a race condition in classes derived from
2154 threading.local: the first member set by a thread could be saved in
2155 another thread's dictionary.
2156
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002157- Issue #3004: Minor change to slice.indices(): the start and stop
2158 arguments are now treated identically, making the behaviour easier
2159 to describe and understand. For example, slice(None, -10,
2160 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2161 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2162 10, -1).
2163
Georg Brandl278fc502008-07-19 12:46:12 +00002164- Issue #3219: Calling a function with repeated keyword arguments,
2165 f(a=2, a=23), would not cause a syntax error. This was a regression

Georg Brandl5cc774e2008-06-11 20:28:06 +00002616 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002617
2618 This is controlled by the configure argument ``--with-universal-archs``:
2619
2620 - ``--with-universal-archs=all``: install 4-way universal
2621
2622 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2623
2624 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2625

Georg Brandl3ee81df2008-05-17 18:14:43 +00002678- Issue #1631171: Re-implement the 'warnings' module in C (the
2679 original Python code has been kept as backup). This will allow for
2680 using the 'warning's machinery in such places as the parser where
2681 use of pure Python code is not possible. Both the ``showarning()``
2682 and ``formatwarning()`` gain an optional 'line' argument which is
2683 not called by default for backwards-compatibility reasons. Setting
2684 ``warnings.showwarning()`` to an implementation that lacks support
2685 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002748- Issue #2550: The approach used by client/server code for obtaining
2749 ports to listen on in network-oriented tests has been refined in an
2750 effort to facilitate running multiple instances of the entire
2751 regression test suite in parallel without issue.
2752 test_support.bind_port() has been fixed such that it will always
2753 return a unique port -- which wasn't always the case with the
2754 previous implementation, especially if socket options had been set
2755 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2756 new implementation of bind_port() will actually raise an exception
2757 if it is passed an AF_INET/SOCK_STREAM socket with either the
2758 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2759 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2760 the socket it's been passed. This currently only applies to
2761 Windows. This option prevents any other sockets from binding to the
2762 host/port we've bound to, thus removing the possibility of the
2763 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2764 when a second SOCK_STREAM socket binds and accepts to a host/port
2765 that's already been bound by another socket. The optional preferred
2766 port parameter to bind_port() has been removed. Under no
2767 circumstances should tests be hard coding ports!
2768
2769 test_support.find_unused_port() has also been introduced, which will
2770 pass a temporary socket object to bind_port() in order to obtain an
2771 unused port. The temporary socket object is then closed and
2772 deleted, and the port is returned. This method should only be used
2773 for obtaining an unused port in order to pass to an external program
2774 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2775 a parameter to a server-oriented class that doesn't give you direct
2776 access to the underlying socket used.
2777
2778 Finally, test_support.HOST has been introduced, which should be used
2779 for the host argument of any relevant socket calls (i.e. bind and
2780 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002781
2782 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002783 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002784 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2785 test_asynchat and test_socket_ssl.
2786
Georg Brandl3ee81df2008-05-17 18:14:43 +00002787 It is now possible for multiple instances of the regression test
2788 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00002992- The bundled libffi copy is now in sync with the recently released
2993 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2995 files are used. On all linux systems the --with-system-ffi
2996 configure option defaults to "yes".

3055-----------------
3056
Fred Drakea8ee94b2008-03-01 02:45:07 +00003057- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003058 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003059
Georg Brandlad61bc82008-02-23 15:11:18 +00003060- Issue #2067: file.__exit__() now calls subclasses' close() method.
3061
3062- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003063
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003064- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003065 issue 215555 for a discussion.
3066
Eric Smitha73fbe72008-02-23 03:09:44 +00003067- Added the future_builtins module, which contains hex() and oct().
3068 These are the PEP 3127 version of these functions, designed to be
3069 compatible with the hex() and oct() builtins from Python 3.0. They
3070 differ slightly in their output formats from the existing, unchanged
3071 Python 2.6 builtins. The expected usage of the future_builtins
3072 module is:
3073 from future_builtins import hex, oct
3074
Eric Smith7ef40bf2008-02-20 23:34:22 +00003075- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3076 exponents for exponents with absolute value < 100. Follows C99
3077 standard. This is a change on Windows, which would use 3 digits.
3078 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3079 so that any alterations it does to the resulting string will be
3080 available in stringlib/formatter.h (for float.__format__).
3081
Eric Smith5a3c1352008-02-19 13:21:56 +00003082- Implemented PEP 3101, Advanced String Formatting. This adds a new
3083 builtin format(); a format() method for str and unicode; a
3084 __format__() method to object, str, unicode, int, long, float, and
3085 datetime; the class string.Formatter; and the C API
3086 PyObject_Format().
3087
Georg Brandl3ee81df2008-05-17 18:14:43 +00003088- Fixed several potential crashes, all caused by specially crafted
3089 __del__ methods exploiting objects in temporarily inconsistent
3090 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003091
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003092- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003093 prevent a possible crash: an Abstract Base Class would try to access
3094 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003095
Georg Brandl3ee81df2008-05-17 18:14:43 +00003096- Fixed repr() and str() of complex numbers with infinity or nan as
3097 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003098
Georg Brandl3ee81df2008-05-17 18:14:43 +00003099- Clear all free lists during a gc.collect() of the highest generation
3100 in order to allow pymalloc to free more arenas. Python may give back
3101 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Issue #2045: Fix an infinite recursion triggered when printing a
3104 subclass of collections.defaultdict, if its default_factory is set
3105 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003106
Christian Heimesf75dbef2008-02-08 00:11:31 +00003107- Fixed a minor memory leak in dictobject.c. The content of the free
3108 list was not freed on interpreter shutdown.
3109
Georg Brandl5a7eca12010-03-21 19:29:04 +00003110- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003111 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003112
Georg Brandl3ee81df2008-05-17 18:14:43 +00003113- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3114 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003115 to compact the internal free lists of pre-allocted ints and floats.
3116
Georg Brandl3ee81df2008-05-17 18:14:43 +00003117- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3118 calls. Python expected the return type int but the fork familie
3119 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003120
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3122 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003123
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3125 with the collections.Sequence API.

3131 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003132
Georg Brandl3ee81df2008-05-17 18:14:43 +00003133- Patch #1473257: generator objects gain a gi_code attribute. This is
3134 the same object as the func_code attribute of the function that
3135 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003136
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- Issue #1920: "while 0" statements were completely removed by the
3138 compiler, even in the presence of an "else" clause, which is
3139 supposed to be run when the condition is false. Now the compiler
3140 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003141
Guido van Rossumeead05f2008-01-24 18:21:02 +00003142- A few crashers fixed: weakref_in_del.py (issue #1377858);
3143 loosing_dict_ref.py (issue #1303614, test67.py);
3144 borrowed_ref_[34].py (not in tracker).
3145
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003146- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003147 suppressed while an extension is loaded by calling SetErrorMode in
3148 dynload_win.c. The error is still reported properly.
3149
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003151 several extension methods and modules do not work without unicode
3152 support.
3153
Georg Brandl26543b12008-01-21 18:36:51 +00003154- Issue #1882: when compiling code from a string, encoding cookies in the
3155 second line of code were not always recognized correctly.
3156
Georg Brandl14404b62008-01-19 19:27:05 +00003157- Issue #1679: "0x" was taken as a valid integer literal.
3158
Georg Brandl6caad7d2008-01-26 14:19:22 +00003159- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003160 added.
3161
Christian Heimesc94e2b52008-01-14 04:13:37 +00003162- sys.float_info / PyFloat_GetInfo: The floating point information
3163 object was converted from a dict to a specialized structseq object.
3164
Georg Brandl3ee81df2008-05-17 18:14:43 +00003165- Patch #1816: Added sys.flags structseq. It exposes the status of
3166 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003167
Georg Brandl3ee81df2008-05-17 18:14:43 +00003168- Objects/structseq.c: Implemented new structseq representation. The
3169 patch makes structseqs (e.g. the return value of os.stat) more
3170 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003171
Georg Brandl3ee81df2008-05-17 18:14:43 +00003172- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003194 and INF. float("nan"), float("inf") and float("-inf") now work on
3195 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003196
Georg Brandl3ee81df2008-05-17 18:14:43 +00003197- Compiler now generates simpler and faster code for dictionary
3198 literals. The oparg for BUILD_MAP now indicates an estimated
3199 dictionary size. There is a new opcode, STORE_MAP, for adding
3200 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003229- Patch #1739468: Directories and zipfiles containing a __main__.py
3230 file can now be directly executed by passing their name to the
3231 interpreter. The directory/zipfile is automatically inserted as the
3232 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003234- Issue #1265: Fix a problem with sys.settrace, if the tracing
3235 function uses a generator expression when at the same time the
3236 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003237
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003238- sets and frozensets now have an isdisjoint() method.

3243
Georg Brandl5a7eca12010-03-21 19:29:04 +00003244- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3246 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003247
Georg Brandl3ee81df2008-05-17 18:14:43 +00003248- Issue #1686386: Tuple's tp_repr did not take into account the
3249 possibility of having a self-referential tuple, which is possible
3250 from C code. Nor did object's tp_str consider that a type's tp_str
3251 could do something that could lead to an inifinite recursion.
3252 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3253 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003254
Georg Brandl3ee81df2008-05-17 18:14:43 +00003255- Issue #1164: It was possible to trigger deadlock when using the
3256 'print' statement to write to a file since the GIL was not released
3257 as needed. Now PyObject_Print() does the right thing along with
3258 various tp_print implementations of the built-in types and those in
3259 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003260
Georg Brandl3ee81df2008-05-17 18:14:43 +00003261- Issue #1147: Exceptions were directly allowing string exceptions in
3262 their throw() method even though string exceptions no longer
3263 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003264
Georg Brandl3ee81df2008-05-17 18:14:43 +00003265- Issue #1096: Prevent a segfault from getting the repr of a very
3266 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003267
Brett Cannon1e534b52007-09-07 04:18:30 +00003268- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003269 PyObject_Call() never calling back out to Python code to trigger
3270 recursion depth updates/checks. Required the creation of a static
3271 RuntimeError instance in case normalizing an exception put the
3272 recursion check value past its limit. Fixes crashers
3273 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003274
Georg Brandl3ee81df2008-05-17 18:14:43 +00003275- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003288- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003289 __*__ attributes. (Some already existed, e.g., __doc__ and
3290 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003291
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003292- Add -3 option to the interpreter to warn about features that are
3293 deprecated and will be changed/removed in Python 3.0.
3294
Georg Brandl2134e752007-05-21 20:34:16 +00003295- Patch #1686487: you can now pass any mapping after '**' in function
3296 calls.
3297
Collin Winter62903052007-05-18 23:11:24 +00003298- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299 "except E as target:". This is to provide forwards compatibility
3300 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003301
Brett Cannon229cee22007-05-05 01:34:02 +00003302- Deprecate BaseException.message as per PEP 352.
3303
Georg Brandl3ee81df2008-05-17 18:14:43 +00003304- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003305 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003306
Vinay Sajip8549ce32007-05-06 17:53:37 +00003307- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003308 setting a plain string, ie don't expand to single letter identifiers.
3309
Raymond Hettinger13936692007-04-11 18:40:58 +00003310- Request #1191699: Slices can now be pickled.
3311
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003312- Request #1193128: str.translate() now allows a None argument for
3313 translations that only remove characters without re-mapping the
3314 remaining characters.
3315
Georg Brandl5cb76c12007-03-21 09:00:39 +00003316- Patch #1682205: a TypeError while unpacking an iterable is no longer
3317 masked by a generic one with the message "unpack non-sequence".
3318
Neal Norwitzaa754b72007-03-21 06:39:48 +00003319- Remove unused file Python/fmod.c.
3320
Guido van Rossum143b5642007-03-23 04:58:42 +00003321- Bug #1683368: The object.__init__() and object.__new__() methods are
3322 now stricter in rejecting excess arguments. The only time when
3323 either allows excess arguments is when it is not overridden and the
3324 other one is. For backwards compatibility, when both are
3325 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003326 warning later). Also, type.__init__() insists on the same signature
3327 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003328
Georg Brandl3ee81df2008-05-17 18:14:43 +00003329- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3330 object to complex using its __complex__() method before falling back
3331 to the __float__() method. Therefore, the functions in the cmath
3332 module now can operate on objects that define a __complex__()
3333 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003334
Georg Brandl3ee81df2008-05-17 18:14:43 +00003335- Patch #1623563: allow __class__ assignment for classes with
3336 __slots__. The old and the new class are still required to have the
3337 same slot names.

3343 ``object.__reduce_ex__()`` is called with an object that is faking
3344 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003345
Georg Brandl3ee81df2008-05-17 18:14:43 +00003346- Patch #1680015: Don't modify __slots__ tuple if it contains an

3350
Georg Brandl7b9c5552007-03-12 14:30:05 +00003351- Bug #1678647: write a newline after printing an exception in any
3352 case, even when converting the value to a string failed.
3353
Georg Brandl871f1bc2007-03-12 13:17:36 +00003354- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003355 its argument, if it exists. If not, it will work like before. This
3356 allows customizing the output of dir() in the presence of a
3357 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- Patch #1491866: change the complex() constructor to allow
3366 parthensized forms. This means complex(repr(x)) now works instead of
3367 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003368
Georg Brandlaa2321b2007-03-07 00:40:28 +00003369- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003370 makes the filenames the warning module prints much more sensible
3371 when a PYTHONSTARTUP file is used.

Georg Brandl098cd692007-03-06 12:17:50 +00003383
Georg Brandl0fca97a2007-03-05 22:28:08 +00003384- Patch #1674228: when assigning a slice (old-style), check for the
3385 sq_ass_slice instead of the sq_slice slot.
3386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- When printing an unraisable error, don't print exceptions. before
3388 the name. This duplicates the behavior whening normally printing
3389 exceptions.

4017 -- the failure just occurred later, with a more cumbersome
4018 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004299- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4300 with RFC 3207 and forgets any knowledge obtained from the server not
4301 obtained from the TLS negotiation itself. Patch contributed by Bill
4302 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004303
Georg Brandl3ee81df2008-05-17 18:14:43 +00004304- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004305 that the SMTP.starttls() caller no longer needs to call ehlo()
4306 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004307 does not claim to support starttls. Adds the
4308 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4309 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004363- itertools.chain() now has an alternate constructor,

4389 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4390 silently miscode subclasses of those types. Now, it raises a
4391 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004392

Georg Brandl3ee81df2008-05-17 18:14:43 +00004407 time so that opening a database previously created with the DB_DUP
4408 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4409 opens. Specifically: dictionary assignment to a DB object will
4410 replace all values for a given key when the database allows
4411 duplicate values. DB users should use DB.put(k, v) when they want
4412 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004413

4419 characters with ASCII value less than 32. Also, it correctly quotes
4420 dots only if they occur on a single line, as opposed to the previous
4421 behavior of quoting dots if they are the second character of any
4422 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004423

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004691- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004692 periodic threadstate and signal checking in tight loops. By
4693 default, this option is turned-off. It should only be enabled in
4694 debugged, performance critical applications.

4746
Georg Brandl3ee81df2008-05-17 18:14:43 +00004747- Unified naming convention for free lists and their limits. All free
4748 lists in Object/ are named ``free_list``, the counter ``numfree``
4749 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4750 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004751
Georg Brandl3ee81df2008-05-17 18:14:43 +00004752- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4753 to ``PyTuple_SetItem``, it can be used to populate a brand new
4754 frozenset; but it does not steal a reference to the added item.

4766
Georg Brandl3ee81df2008-05-17 18:14:43 +00004767- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4768 of w# format code incorrectly truncated the length to an int, even
4769 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4770 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004771
Georg Brandl3ee81df2008-05-17 18:14:43 +00004772- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4792
4793- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4794 outside of pystate.c and should not be necessary.
4795
Georg Brandl3ee81df2008-05-17 18:14:43 +00004796- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4797 absolute imports. In earlier versions they might have used relative
4798 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004799
Georg Brandl3ee81df2008-05-17 18:14:43 +00004800- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4801 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004802
Georg Brandl3ee81df2008-05-17 18:14:43 +00004803- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004828- Removed the macfs module. It had been deprecated since Python 2.5.
4829 This lead to the deprecation of macostools.touched() as it relied
