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

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

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>`_.

1570*Release date: 04-Dec-2008*
1571
1572Core and Builtins
1573-----------------
1574
1575- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1576 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1577 instead of throwing a MemoryError.
1578
1579- Issue #4367: Python would segfault during compiling when the unicodedata
1580 module couldn't be imported and \N escapes were present.
1581
1582- Issue #4348: Some bytearray methods returned that didn't cause any change to
1583 the bytearray, returned the same bytearray instead of a copy.
1584
1585- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1586
1587- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1588
1589- Issue #4048: The parser module now correctly validates relative imports.
1590
1591- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1592 exec statement.

1595 method does not return iterators for the 4th and 5th items.
1596
1597- Issue #4209: Enabling unicode_literals and the print_function in the same
1598 __future__ import didn't work.
1599
1600- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1601 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1602 really executed because I cannot move to such directory on win2k)
1603
1604- Issue #4069: When set.remove(element) is used with a set element, the element
1605 is temporarily replaced with an equivalent frozenset. But the eventual
1606 KeyError would always report the empty frozenset([]) as the missing key. Now
1607 it correctly refers to the initial element.
1608
1609- Fixed C99 style comments in several files. Python is now C89 compatible
1610 again.

1758
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001759- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1760 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1761 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1762 ``printf`` function, whereas PyString_FromFormat has an independent
1763 implementation and uses "%zd" on all platforms for size_t values.
1764 This makes a difference on win64, where ``printf`` needs "%Id" to display
1765 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001785 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1786 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1787 when given a tuple of classes as second argument, were looking up
1788 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1789 type object.

1882-----------------
1883
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001884- Issue #2975: When compiling several extension modules with Visual Studio 2008
1885 from the same python interpreter, some environment variables would grow
1886 without limit.
1887
Benjamin Peterson37346b22008-08-23 20:27:43 +00001888- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1889 exploitation of poor argument checking.
1890
Gerhard Häringef2276b2008-09-12 13:54:06 +00001891- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1892
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00001893- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
1894 remaining ones have "pysqlite_" prefix.
1895
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001896- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00001903- Issue #3781: Add test.test_support.check_warnings() as a convenience
1904 wrapper for warnings.catch_warnings() that makes it easier to check
1905 that expected warning messages are being reported.
1906
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001907- Issue #3796: Some tests functions were not enabled in test_float.

1915
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001916- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001925What's New in Python 2.6 beta 3?
1926================================
1927
Barry Warsaw07a4a382008-08-21 01:15:08 +00001928*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001929
1930Core and Builtins
1931-----------------
1932
Guido van Rossumf8402962008-08-20 15:01:50 +00001933- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1934 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1935 extensions do not automatically benefit from the class attribute
1936 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1937 to their tp_flags field if they care. This is a backwards
1938 compatibility feature; in 3.0, all types will use the cache by
1939 default.
1940
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001941- Keyword arguments can now follow starred arguments. (``f(a, *args,
1942 keyword=23)`` is now valid syntax.)
1943
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001944- ctypes function pointers that are COM methods have a boolean True
1945 value again.
1946
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001947- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1948 by denying s# to parse objects that have a releasebuffer procedure,
1949 and introducing s*.
1950
Georg Brandl1e13ea92008-08-11 09:07:59 +00001951- Issue #3537: Fix an assertion failure when an empty but presized dict
1952 object was stored in the freelist.
1953
Mark Dickinsonb6467572008-08-04 21:30:09 +00001954- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1955 ValueError consistently across platforms.
1956
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001957- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1958 (64bit Unix, for example), unichr() would truncate its argument and return
1959 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1960
Neal Norwitze7d8be82008-07-31 17:17:14 +00001961- Apply security patches from Apple.
1962
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001963- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1964 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1965
Antoine Pitrou92f82162008-07-25 22:22:08 +00001966- Issue #1819: function calls with several named parameters are now on
1967 average 35% faster (as measured by pybench).
1968
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001969- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1970 the python debugger steps into a class statement: the free variables (local
1971 variables defined in an outer scope) would be deleted from the outer scope.
1972
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001973- Issue #2620: Overflow checking when allocating or reallocating memory
1974 was not always being done properly in some python types and extension
1975 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1976 all been updated to perform better checks and places in the code that
1977 would previously leak memory on the error path when such an allocation
1978 failed have been fixed.
1979
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001980Library
1981-------
1982
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001983- Issue #3612: Added some missing basic types in ctypes.wintypes.
1984
Benjamin Petersone977ad42008-08-20 01:42:01 +00001985- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1986 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1987
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001988- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1989 version reported by these tools does not necessarily follow the python
1990 version numbering scheme, so the module is less strict when parsing it.
1991
Nick Coghlanf70385a2008-08-18 12:42:46 +00001992- Issue #2235: Added Py3k warnings for types which will become unhashable
1993 under the stricter __hash__ inheritance rules in 3.0. Several types
1994 which did not meet the rules for hash invariants and were already
1995 unhashable in 3.0 have now been explicitly flagged as unhashable in
1996 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1997 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1998
Brett Cannon88f801d2008-08-18 00:46:22 +00001999- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2000 imported into the module but exposed as part of the module's API.
2001
Brett Cannon7b96f072008-08-18 00:41:11 +00002002- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2003
Brett Cannon46225e72008-08-18 00:36:52 +00002004- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002006- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2007
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002008- Issue #3575: Incremental decoder's decode function now takes bytearray
2009 by using 's*' instead of 't#'.
2010
Jesus Cea585ad8a2009-07-02 15:37:21 +00002011- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002012 fails unicode conversion on 2nd parameter. (windows only)
2013
Facundo Batista94f243a2008-08-17 03:38:39 +00002014- Issue 2464. urllib2 now supports a malformation in the URL received
2015 in a redirect.
2016
Brett Cannonabe423e2008-08-16 21:47:07 +00002017- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002018 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002019
Facundo Batistaeb90b782008-08-16 14:44:07 +00002020- Issue #2776: fixed small issue when handling an URL with double slash
2021 after a 302 response in the case of not going through a proxy.
2022
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002023- Issue #2676: in the email package, content-type parsing was hanging on
2024 pathological input because of quadratic or exponential behaviour of a
2025 regular expression.
2026
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002027- Issue #3476: binary buffered reading through the new "io" library is now
2028 thread-safe.
2029
Brett Cannonbf3157b2008-08-14 05:00:03 +00002030- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2031 since mimetools itself is deprecated. Because modules are cached, all
2032 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2033
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002034- Issue #3134: shutil referenced undefined WindowsError symbol.
2035
Robert Schuppenies14646332008-08-10 11:01:53 +00002036- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2037 menu entries were not deleted.
2038
Brett Cannon83e81842008-08-09 23:30:55 +00002039- Copied the implementation of reduce() to _functools.reduce() to have a
2040 version that did not raise a DeprecationWarning under -3.
2041
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002042- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2043 a MemoryError rather than silently stop the iteration.
2044
Guido van Rossum59ce9012008-08-09 14:55:34 +00002045- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2046 to _sre.compile() will now be rejected. This should not affect anybody
2047 since the re.compile() function never generates invalid re-bytecode.
2048
Skip Montanaroa032bf42008-08-08 22:52:51 +00002049- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2050 upon first access it can be automatically initialized from the csv file if
2051 it wasn't initialized during instantiation.
2052
Brett Cannon3aa2a492008-08-06 22:28:09 +00002053- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2054 the reload() built-in has been removed.
2055
Brett Cannon7e30b672008-08-04 21:52:25 +00002056- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002057 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2065 raised an AttributeError.
2066
Benjamin Peterson01a24322008-07-28 23:35:27 +00002067- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002068 asking for a specific length. This problem only affected files opened
2069 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002070
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002071- Issue #3449: Update decimal module to use most recent specification
2072 (v. 1.68) and tests (v. 2.58) from IBM.
2073
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002074- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002081- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
2082
2083- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2084 invalid arguments.
2085
2086- Issue #3302: Fix several crashes when calling locale's gettext functions
2087 with None arguments.
2088
2089- Issue #3389: Allow resolving dotted names for handlers in logging
2090 configuration files.
2091
2092- Deprecate the sunaudio module for removal in Python 3.0.
2093
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002094- Issue #3394: zipfile.writestr sets external attributes when passed a
2095 file name rather than a ZipInfo instance, so files are extracted with
2096 mode 0600 rather than 000 under Unix.
2097
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002098- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2099 argument in python 2.5, this broke code that subclassed Popen to include its
2100 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2108-------------
2109
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002110- Issue #2235: the C API function PyObject_HashNotImplemented and its
2111 interaction with the tp_hash slot (added in 2.6b2) are now documented
2112
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002113- Issue #643841: The language reference now provides more detailed
2114 coverage of the lookup process for special methods. The disclaimers
2115 regarding lack of coverage of new-style classes have also been
2116 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002119What's New in Python 2.6 beta 2?
2120================================
2121
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002122*Release date: 17-Jul-2008*
2123
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002124Core and Builtins
2125-----------------
2126
Georg Brandl3e483f62008-07-16 22:57:41 +00002127- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2128 its methods now allow for items objects that can be converted to
2129 an integer using operator.index().
2130
Mark Dickinson64b7e502008-07-16 09:40:03 +00002131- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2132 produced a ValueError instead of giving the correct float.
2133
Eric Smitha5fa5a22008-07-16 00:11:49 +00002134- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2135 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2136
Mark Dickinson7103aa42008-07-15 19:08:33 +00002137- Issue #3008: the float type has a new instance method 'float.hex'
2138 and a new class method 'float.fromhex' to convert floating-point
2139 numbers to and from hexadecimal strings, respectively.
2140
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002141- Issue #2235: __hash__ is once again inherited by default. To allow
2142 collections.Hashable to remain meaningful in the presence of the
2143 default hash implementation (object.__hash__), it is now possible
2144 to explicit block inheritance of hash by setting __hash__=None at
2145 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2146 level.
2147
Nick Coghlanb028f502008-07-13 14:52:36 +00002148- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2149 the parent module cannot be found while performing an absolute import.
2150 This means that an incorrectly defined __package__ attribute will
2151 now only prevent relative imports in that module rather than causing
2152 all imports from that module to fail.
2153
Nick Coghlan14ff9942008-07-08 14:21:42 +00002154- Issue #2517: Allow unicode messages in Exceptions again by correctly
2155 bypassing the instance dictionary when looking up __unicode__ on
2156 new-style classes.
2157
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002158- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2159 set to a custom object whose write() method happens to install
2160 another file in sys.stdout.
2161
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002162- Issue #3088: Corrected a race condition in classes derived from
2163 threading.local: the first member set by a thread could be saved in
2164 another thread's dictionary.
2165
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002166- Issue #3004: Minor change to slice.indices(): the start and stop
2167 arguments are now treated identically, making the behaviour easier
2168 to describe and understand. For example, slice(None, -10,
2169 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and

Georg Brandl5cc774e2008-06-11 20:28:06 +00002625 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002626
2627 This is controlled by the configure argument ``--with-universal-archs``:
2628
2629 - ``--with-universal-archs=all``: install 4-way universal
2630
2631 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2632
2633 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2634

Georg Brandl3ee81df2008-05-17 18:14:43 +00002687- Issue #1631171: Re-implement the 'warnings' module in C (the
2688 original Python code has been kept as backup). This will allow for
2689 using the 'warning's machinery in such places as the parser where
2690 use of pure Python code is not possible. Both the ``showarning()``
2691 and ``formatwarning()`` gain an optional 'line' argument which is
2692 not called by default for backwards-compatibility reasons. Setting
2693 ``warnings.showwarning()`` to an implementation that lacks support
2694 for the ``line`` argument will raise a DeprecationWarning.

2718
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002719- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00002757- Issue #2550: The approach used by client/server code for obtaining
2758 ports to listen on in network-oriented tests has been refined in an
2759 effort to facilitate running multiple instances of the entire
2760 regression test suite in parallel without issue.
2761 test_support.bind_port() has been fixed such that it will always
2762 return a unique port -- which wasn't always the case with the
2763 previous implementation, especially if socket options had been set
2764 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2765 new implementation of bind_port() will actually raise an exception
2766 if it is passed an AF_INET/SOCK_STREAM socket with either the
2767 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2768 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2769 the socket it's been passed. This currently only applies to
2770 Windows. This option prevents any other sockets from binding to the
2771 host/port we've bound to, thus removing the possibility of the
2772 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2773 when a second SOCK_STREAM socket binds and accepts to a host/port
2774 that's already been bound by another socket. The optional preferred
2775 port parameter to bind_port() has been removed. Under no
2776 circumstances should tests be hard coding ports!
2777
2778 test_support.find_unused_port() has also been introduced, which will
2779 pass a temporary socket object to bind_port() in order to obtain an
2780 unused port. The temporary socket object is then closed and
2781 deleted, and the port is returned. This method should only be used
2782 for obtaining an unused port in order to pass to an external program
2783 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2784 a parameter to a server-oriented class that doesn't give you direct
2785 access to the underlying socket used.
2786
2787 Finally, test_support.HOST has been introduced, which should be used
2788 for the host argument of any relevant socket calls (i.e. bind and
2789 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002790
2791 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002792 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002793 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2794 test_asynchat and test_socket_ssl.
2795
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796 It is now possible for multiple instances of the regression test
2797 suite to run in parallel without issue.

3065
Fred Drakea8ee94b2008-03-01 02:45:07 +00003066- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003067 644. The mode is now inherited from the py file.

3070
3071- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003072
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003073- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003074 issue 215555 for a discussion.
3075
Eric Smitha73fbe72008-02-23 03:09:44 +00003076- Added the future_builtins module, which contains hex() and oct().
3077 These are the PEP 3127 version of these functions, designed to be
3078 compatible with the hex() and oct() builtins from Python 3.0. They
3079 differ slightly in their output formats from the existing, unchanged
3080 Python 2.6 builtins. The expected usage of the future_builtins
3081 module is:
3082 from future_builtins import hex, oct
3083
Eric Smith7ef40bf2008-02-20 23:34:22 +00003084- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3085 exponents for exponents with absolute value < 100. Follows C99
3086 standard. This is a change on Windows, which would use 3 digits.
3087 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3088 so that any alterations it does to the resulting string will be
3089 available in stringlib/formatter.h (for float.__format__).
3090
Eric Smith5a3c1352008-02-19 13:21:56 +00003091- Implemented PEP 3101, Advanced String Formatting. This adds a new
3092 builtin format(); a format() method for str and unicode; a
3093 __format__() method to object, str, unicode, int, long, float, and
3094 datetime; the class string.Formatter; and the C API
3095 PyObject_Format().
3096
Georg Brandl3ee81df2008-05-17 18:14:43 +00003097- Fixed several potential crashes, all caused by specially crafted
3098 __del__ methods exploiting objects in temporarily inconsistent
3099 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003100
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003101- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102 prevent a possible crash: an Abstract Base Class would try to access
3103 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003104
Georg Brandl3ee81df2008-05-17 18:14:43 +00003105- Fixed repr() and str() of complex numbers with infinity or nan as
3106 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003107
Georg Brandl3ee81df2008-05-17 18:14:43 +00003108- Clear all free lists during a gc.collect() of the highest generation
3109 in order to allow pymalloc to free more arenas. Python may give back
3110 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003111
Georg Brandl3ee81df2008-05-17 18:14:43 +00003112- Issue #2045: Fix an infinite recursion triggered when printing a
3113 subclass of collections.defaultdict, if its default_factory is set
3114 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003115
Christian Heimesf75dbef2008-02-08 00:11:31 +00003116- Fixed a minor memory leak in dictobject.c. The content of the free
3117 list was not freed on interpreter shutdown.
3118
Georg Brandl5a7eca12010-03-21 19:29:04 +00003119- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003120 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003121
Georg Brandl3ee81df2008-05-17 18:14:43 +00003122- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3123 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003124 to compact the internal free lists of pre-allocted ints and floats.
3125
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3127 calls. Python expected the return type int but the fork familie
3128 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003129
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3131 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003132
Georg Brandl3ee81df2008-05-17 18:14:43 +00003133- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3134 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003135

Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3140 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003141
Georg Brandl3ee81df2008-05-17 18:14:43 +00003142- Patch #1473257: generator objects gain a gi_code attribute. This is
3143 the same object as the func_code attribute of the function that
3144 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003145
Georg Brandl3ee81df2008-05-17 18:14:43 +00003146- Issue #1920: "while 0" statements were completely removed by the
3147 compiler, even in the presence of an "else" clause, which is
3148 supposed to be run when the condition is false. Now the compiler
3149 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003150
Guido van Rossumeead05f2008-01-24 18:21:02 +00003151- A few crashers fixed: weakref_in_del.py (issue #1377858);
3152 loosing_dict_ref.py (issue #1303614, test67.py);
3153 borrowed_ref_[34].py (not in tracker).
3154
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003155- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003156 suppressed while an extension is loaded by calling SetErrorMode in
3157 dynload_win.c. The error is still reported properly.
3158
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003160 several extension methods and modules do not work without unicode
3161 support.
3162
Georg Brandl26543b12008-01-21 18:36:51 +00003163- Issue #1882: when compiling code from a string, encoding cookies in the
3164 second line of code were not always recognized correctly.
3165
Georg Brandl14404b62008-01-19 19:27:05 +00003166- Issue #1679: "0x" was taken as a valid integer literal.
3167
Georg Brandl6caad7d2008-01-26 14:19:22 +00003168- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003169 added.
3170
Christian Heimesc94e2b52008-01-14 04:13:37 +00003171- sys.float_info / PyFloat_GetInfo: The floating point information
3172 object was converted from a dict to a specialized structseq object.
3173
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174- Patch #1816: Added sys.flags structseq. It exposes the status of
3175 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003176
Georg Brandl3ee81df2008-05-17 18:14:43 +00003177- Objects/structseq.c: Implemented new structseq representation. The
3178 patch makes structseqs (e.g. the return value of os.stat) more
3179 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003180
Georg Brandl3ee81df2008-05-17 18:14:43 +00003181- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003203 and INF. float("nan"), float("inf") and float("-inf") now work on
3204 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003205
Georg Brandl3ee81df2008-05-17 18:14:43 +00003206- Compiler now generates simpler and faster code for dictionary
3207 literals. The oparg for BUILD_MAP now indicates an estimated
3208 dictionary size. There is a new opcode, STORE_MAP, for adding
3209 entries to the dictionary.

3234
Georg Brandl3ee81df2008-05-17 18:14:43 +00003235- Issue #1460: The utf-7 incremental decoder did not accept truncated
3236 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003237
Georg Brandl3ee81df2008-05-17 18:14:43 +00003238- Patch #1739468: Directories and zipfiles containing a __main__.py
3239 file can now be directly executed by passing their name to the
3240 interpreter. The directory/zipfile is automatically inserted as the
3241 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- Issue #1265: Fix a problem with sys.settrace, if the tracing
3244 function uses a generator expression when at the same time the
3245 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003246
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003247- sets and frozensets now have an isdisjoint() method.
3248

3250
Neal Norwitz44f326e2007-10-05 05:29:17 +00003251- Fix warnings found by the new version of the Coverity checker.
3252
Georg Brandl5a7eca12010-03-21 19:29:04 +00003253- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3255 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003257- Issue #1686386: Tuple's tp_repr did not take into account the
3258 possibility of having a self-referential tuple, which is possible
3259 from C code. Nor did object's tp_str consider that a type's tp_str
3260 could do something that could lead to an inifinite recursion.
3261 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3262 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003263
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264- Issue #1164: It was possible to trigger deadlock when using the
3265 'print' statement to write to a file since the GIL was not released
3266 as needed. Now PyObject_Print() does the right thing along with
3267 various tp_print implementations of the built-in types and those in
3268 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003269
Georg Brandl3ee81df2008-05-17 18:14:43 +00003270- Issue #1147: Exceptions were directly allowing string exceptions in
3271 their throw() method even though string exceptions no longer
3272 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003273
Georg Brandl3ee81df2008-05-17 18:14:43 +00003274- Issue #1096: Prevent a segfault from getting the repr of a very
3275 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003276
Brett Cannon1e534b52007-09-07 04:18:30 +00003277- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003278 PyObject_Call() never calling back out to Python code to trigger
3279 recursion depth updates/checks. Required the creation of a static
3280 RuntimeError instance in case normalizing an exception put the
3281 recursion check value past its limit. Fixes crashers
3282 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003297- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003298 __*__ attributes. (Some already existed, e.g., __doc__ and
3299 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003300
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003301- Add -3 option to the interpreter to warn about features that are
3302 deprecated and will be changed/removed in Python 3.0.
3303
Georg Brandl2134e752007-05-21 20:34:16 +00003304- Patch #1686487: you can now pass any mapping after '**' in function
3305 calls.
3306
Collin Winter62903052007-05-18 23:11:24 +00003307- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003308 "except E as target:". This is to provide forwards compatibility
3309 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003310
Brett Cannon229cee22007-05-05 01:34:02 +00003311- Deprecate BaseException.message as per PEP 352.
3312
Georg Brandl3ee81df2008-05-17 18:14:43 +00003313- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003314 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003315
Vinay Sajip8549ce32007-05-06 17:53:37 +00003316- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003317 setting a plain string, ie don't expand to single letter identifiers.
3318
Raymond Hettinger13936692007-04-11 18:40:58 +00003319- Request #1191699: Slices can now be pickled.
3320
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003321- Request #1193128: str.translate() now allows a None argument for
3322 translations that only remove characters without re-mapping the
3323 remaining characters.
3324
Georg Brandl5cb76c12007-03-21 09:00:39 +00003325- Patch #1682205: a TypeError while unpacking an iterable is no longer
3326 masked by a generic one with the message "unpack non-sequence".
3327
Neal Norwitzaa754b72007-03-21 06:39:48 +00003328- Remove unused file Python/fmod.c.
3329
Guido van Rossum143b5642007-03-23 04:58:42 +00003330- Bug #1683368: The object.__init__() and object.__new__() methods are
3331 now stricter in rejecting excess arguments. The only time when
3332 either allows excess arguments is when it is not overridden and the
3333 other one is. For backwards compatibility, when both are
3334 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003335 warning later). Also, type.__init__() insists on the same signature
3336 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003337
Georg Brandl3ee81df2008-05-17 18:14:43 +00003338- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3339 object to complex using its __complex__() method before falling back
3340 to the __float__() method. Therefore, the functions in the cmath
3341 module now can operate on objects that define a __complex__()
3342 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003343
Georg Brandl3ee81df2008-05-17 18:14:43 +00003344- Patch #1623563: allow __class__ assignment for classes with
3345 __slots__. The old and the new class are still required to have the
3346 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003347
Georg Brandl3ee81df2008-05-17 18:14:43 +00003348- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003351- Patch #1462488: Python no longer segfaults when
3352 ``object.__reduce_ex__()`` is called with an object that is faking
3353 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003354
Georg Brandl3ee81df2008-05-17 18:14:43 +00003355- Patch #1680015: Don't modify __slots__ tuple if it contains an

3359
Georg Brandl7b9c5552007-03-12 14:30:05 +00003360- Bug #1678647: write a newline after printing an exception in any
3361 case, even when converting the value to a string failed.
3362
Georg Brandl871f1bc2007-03-12 13:17:36 +00003363- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003364 its argument, if it exists. If not, it will work like before. This
3365 allows customizing the output of dir() in the presence of a
3366 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003367
Collin Winter276887b2007-03-12 16:11:39 +00003368- Patch #922167: Python no longer segfaults when faced with infinitely
3369 self-recursive reload() calls (as reported by bug #742342).
3370
Georg Brandl3ee81df2008-05-17 18:14:43 +00003371- Patch #1675981: remove unreachable code from ``type.__new__()``
3372 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003374- Patch #1491866: change the complex() constructor to allow
3375 parthensized forms. This means complex(repr(x)) now works instead of
3376 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003377
Georg Brandlaa2321b2007-03-07 00:40:28 +00003378- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003379 makes the filenames the warning module prints much more sensible
3380 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003381
Georg Brandl49aafc92007-03-07 00:34:46 +00003382- Variant of patch #697613: don't exit the interpreter on a SystemExit
3383 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384 variable is given, but break into the interactive interpreter just
3385 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003390- Bug #1674503: close the file opened by execfile() in an error
3391 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003392
Georg Brandl0fca97a2007-03-05 22:28:08 +00003393- Patch #1674228: when assigning a slice (old-style), check for the
3394 sq_ass_slice instead of the sq_slice slot.
3395
Georg Brandl3ee81df2008-05-17 18:14:43 +00003396- When printing an unraisable error, don't print exceptions. before
3397 the name. This duplicates the behavior whening normally printing
3398 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003399
Georg Brandl3ee81df2008-05-17 18:14:43 +00003400- Bug #1653736: Properly discard third argument to

3407 created a weakref on itself during a __del__ call for new-style
3408 classes (classic classes still have the bug).

3455
Armin Rigo7ccbca92006-10-04 12:17:45 +00003456- A number of places, including integer negation and absolute value,
3457 were fixed to not rely on undefined behaviour of the C compiler
3458 anymore.

3964
Georg Brandl92a6bae2007-03-13 17:43:32 +00003965- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003966 are set for invalid interpolation sequences that would lead to

4023 TestCase and TestSuite subclasses (not instances) are no longer
4024 accepted in TestSuite.addTest(). This should cause no
4025 incompatibility since it never made sense with ordinary subclasses
4026 -- the failure just occurred later, with a more cumbersome
4027 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004308- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4309 with RFC 3207 and forgets any knowledge obtained from the server not
4310 obtained from the TLS negotiation itself. Patch contributed by Bill
4311 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004312
Georg Brandl3ee81df2008-05-17 18:14:43 +00004313- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004314 that the SMTP.starttls() caller no longer needs to call ehlo()
4315 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004316 does not claim to support starttls. Adds the
4317 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4398 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4399 silently miscode subclasses of those types. Now, it raises a
4400 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004401

Georg Brandl3ee81df2008-05-17 18:14:43 +00004416 time so that opening a database previously created with the DB_DUP
4417 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4418 opens. Specifically: dictionary assignment to a DB object will
4419 replace all values for a given key when the database allows
4420 duplicate values. DB users should use DB.put(k, v) when they want
4421 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004422

4428 characters with ASCII value less than 32. Also, it correctly quotes
4429 dots only if they occur on a single line, as opposed to the previous
4430 behavior of quoting dots if they are the second character of any
4431 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004432

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004700- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004701 periodic threadstate and signal checking in tight loops. By
4702 default, this option is turned-off. It should only be enabled in
4703 debugged, performance critical applications.

4755
Georg Brandl3ee81df2008-05-17 18:14:43 +00004756- Unified naming convention for free lists and their limits. All free
4757 lists in Object/ are named ``free_list``, the counter ``numfree``

4759 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004760
Georg Brandl3ee81df2008-05-17 18:14:43 +00004761- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4762 to ``PyTuple_SetItem``, it can be used to populate a brand new
4763 frozenset; but it does not steal a reference to the added item.

4775
Georg Brandl3ee81df2008-05-17 18:14:43 +00004776- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4777 of w# format code incorrectly truncated the length to an int, even
4778 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4779 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004780
Georg Brandl3ee81df2008-05-17 18:14:43 +00004781- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4803 outside of pystate.c and should not be necessary.
4804
Georg Brandl3ee81df2008-05-17 18:14:43 +00004805- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4806 absolute imports. In earlier versions they might have used relative
4807 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004808
Georg Brandl3ee81df2008-05-17 18:14:43 +00004809- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4810 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004811
Georg Brandl3ee81df2008-05-17 18:14:43 +00004812- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004837- Removed the macfs module. It had been deprecated since Python 2.5.
4838 This lead to the deprecation of macostools.touched() as it relied
4839 solely on macfs and was a no-op under OS X.
