13-----------------

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

72
Antoine Pitrou52ca5162010-05-21 17:22:43 +000073C-API
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>`_.

1573What's New in Python 2.6.1
1574==========================
1575
1576*Release date: 04-Dec-2008*
1577
1578Core and Builtins
1579-----------------
1580
1581- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1582 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1583 instead of throwing a MemoryError.
1584
1585- Issue #4367: Python would segfault during compiling when the unicodedata
1586 module couldn't be imported and \N escapes were present.
1587
1588- Issue #4348: Some bytearray methods returned that didn't cause any change to
1589 the bytearray, returned the same bytearray instead of a copy.
1590
1591- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1592
1593- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1594
1595- Issue #4048: The parser module now correctly validates relative imports.
1596
1597- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1598 exec statement.

1600- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1601 method does not return iterators for the 4th and 5th items.
1602
1603- Issue #4209: Enabling unicode_literals and the print_function in the same
1604 __future__ import didn't work.
1605
1606- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1607 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1608 really executed because I cannot move to such directory on win2k)
1609
1610- Issue #4069: When set.remove(element) is used with a set element, the element
1611 is temporarily replaced with an equivalent frozenset. But the eventual
1612 KeyError would always report the empty frozenset([]) as the missing key. Now
1613 it correctly refers to the initial element.
1614
1615- Fixed C99 style comments in several files. Python is now C89 compatible
1616 again.

1764
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001765- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1766 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1767 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1768 ``printf`` function, whereas PyString_FromFormat has an independent
1769 implementation and uses "%zd" on all platforms for size_t values.
1770 This makes a difference on win64, where ``printf`` needs "%Id" to display
1771 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001791 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1792 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1794 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1795 type object.

1888-----------------
1889
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001890- Issue #2975: When compiling several extension modules with Visual Studio 2008
1891 from the same python interpreter, some environment variables would grow
1892 without limit.
1893
Benjamin Peterson37346b22008-08-23 20:27:43 +00001894- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1910 wrapper for warnings.catch_warnings() that makes it easier to check
1911 that expected warning messages are being reported.
1912

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001931What's New in Python 2.6 beta 3?
1932================================
1933
Barry Warsaw07a4a382008-08-21 01:15:08 +00001934*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001935
1936Core and Builtins
1937-----------------
1938
Guido van Rossumf8402962008-08-20 15:01:50 +00001939- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1940 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1941 extensions do not automatically benefit from the class attribute
1942 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1943 to their tp_flags field if they care. This is a backwards
1944 compatibility feature; in 3.0, all types will use the cache by
1945 default.
1946
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001947- Keyword arguments can now follow starred arguments. (``f(a, *args,
1948 keyword=23)`` is now valid syntax.)
1949
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001950- ctypes function pointers that are COM methods have a boolean True
1951 value again.
1952
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001953- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1954 by denying s# to parse objects that have a releasebuffer procedure,
1955 and introducing s*.
1956
Georg Brandl1e13ea92008-08-11 09:07:59 +00001957- Issue #3537: Fix an assertion failure when an empty but presized dict
1958 object was stored in the freelist.
1959
Mark Dickinsonb6467572008-08-04 21:30:09 +00001960- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1961 ValueError consistently across platforms.
1962
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001963- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1964 (64bit Unix, for example), unichr() would truncate its argument and return
1965 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1966
Neal Norwitze7d8be82008-07-31 17:17:14 +00001967- Apply security patches from Apple.
1968
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001969- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1970 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1971
Antoine Pitrou92f82162008-07-25 22:22:08 +00001972- Issue #1819: function calls with several named parameters are now on
1973 average 35% faster (as measured by pybench).
1974
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001975- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1976 the python debugger steps into a class statement: the free variables (local
1977 variables defined in an outer scope) would be deleted from the outer scope.
1978
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001979- Issue #2620: Overflow checking when allocating or reallocating memory
1980 was not always being done properly in some python types and extension
1981 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1982 all been updated to perform better checks and places in the code that
1983 would previously leak memory on the error path when such an allocation
1984 failed have been fixed.
1985
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001986Library
1987-------
1988
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001989- Issue #3612: Added some missing basic types in ctypes.wintypes.
1990
Benjamin Petersone977ad42008-08-20 01:42:01 +00001991- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1992 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1993
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001994- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1995 version reported by these tools does not necessarily follow the python
1996 version numbering scheme, so the module is less strict when parsing it.
1997
Nick Coghlanf70385a2008-08-18 12:42:46 +00001998- Issue #2235: Added Py3k warnings for types which will become unhashable
1999 under the stricter __hash__ inheritance rules in 3.0. Several types
2000 which did not meet the rules for hash invariants and were already
2001 unhashable in 3.0 have now been explicitly flagged as unhashable in
2002 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2003 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2004
Brett Cannon88f801d2008-08-18 00:46:22 +00002005- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2006 imported into the module but exposed as part of the module's API.
2007
Brett Cannon7b96f072008-08-18 00:41:11 +00002008- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2009
Brett Cannon46225e72008-08-18 00:36:52 +00002010- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2013
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002014- Issue #3575: Incremental decoder's decode function now takes bytearray
2015 by using 's*' instead of 't#'.
2016
Jesus Cea585ad8a2009-07-02 15:37:21 +00002017- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002018 fails unicode conversion on 2nd parameter. (windows only)
2019
Facundo Batista94f243a2008-08-17 03:38:39 +00002020- Issue 2464. urllib2 now supports a malformation in the URL received
2021 in a redirect.
2022
Brett Cannonabe423e2008-08-16 21:47:07 +00002023- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002024 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002025
Facundo Batistaeb90b782008-08-16 14:44:07 +00002026- Issue #2776: fixed small issue when handling an URL with double slash
2027 after a 302 response in the case of not going through a proxy.
2028
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002029- Issue #2676: in the email package, content-type parsing was hanging on
2030 pathological input because of quadratic or exponential behaviour of a
2031 regular expression.
2032
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002033- Issue #3476: binary buffered reading through the new "io" library is now
2034 thread-safe.
2035
Brett Cannonbf3157b2008-08-14 05:00:03 +00002036- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2037 since mimetools itself is deprecated. Because modules are cached, all
2038 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2039
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002040- Issue #3134: shutil referenced undefined WindowsError symbol.
2041
Robert Schuppenies14646332008-08-10 11:01:53 +00002042- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2043 menu entries were not deleted.
2044
Brett Cannon83e81842008-08-09 23:30:55 +00002045- Copied the implementation of reduce() to _functools.reduce() to have a
2046 version that did not raise a DeprecationWarning under -3.
2047
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002048- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2049 a MemoryError rather than silently stop the iteration.
2050
Guido van Rossum59ce9012008-08-09 14:55:34 +00002051- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2052 to _sre.compile() will now be rejected. This should not affect anybody
2053 since the re.compile() function never generates invalid re-bytecode.
2054
Skip Montanaroa032bf42008-08-08 22:52:51 +00002055- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2056 upon first access it can be automatically initialized from the csv file if
2057 it wasn't initialized during instantiation.
2058
Brett Cannon3aa2a492008-08-06 22:28:09 +00002059- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2060 the reload() built-in has been removed.
2061
Brett Cannon7e30b672008-08-04 21:52:25 +00002062- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002063 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2071 raised an AttributeError.
2072
Benjamin Peterson01a24322008-07-28 23:35:27 +00002073- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002074 asking for a specific length. This problem only affected files opened
2075 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002076
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002077- Issue #3449: Update decimal module to use most recent specification
2078 (v. 1.68) and tests (v. 2.58) from IBM.

2099
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002100- Issue #3394: zipfile.writestr sets external attributes when passed a
2101 file name rather than a ZipInfo instance, so files are extracted with
2102 mode 0600 rather than 000 under Unix.
2103
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002104- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2105 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002116- Issue #2235: the C API function PyObject_HashNotImplemented and its
2117 interaction with the tp_hash slot (added in 2.6b2) are now documented
2118
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002119- Issue #643841: The language reference now provides more detailed
2120 coverage of the lookup process for special methods. The disclaimers
2121 regarding lack of coverage of new-style classes have also been
2122 removed, since the coverage is now fairly reasonable.

2127
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002128*Release date: 17-Jul-2008*

2131-----------------
2132
Georg Brandl3e483f62008-07-16 22:57:41 +00002133- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2134 its methods now allow for items objects that can be converted to
2135 an integer using operator.index().
2136
Mark Dickinson64b7e502008-07-16 09:40:03 +00002137- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2138 produced a ValueError instead of giving the correct float.
2139
Eric Smitha5fa5a22008-07-16 00:11:49 +00002140- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2141 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2142
Mark Dickinson7103aa42008-07-15 19:08:33 +00002143- Issue #3008: the float type has a new instance method 'float.hex'
2144 and a new class method 'float.fromhex' to convert floating-point
2145 numbers to and from hexadecimal strings, respectively.
2146
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002147- Issue #2235: __hash__ is once again inherited by default. To allow
2148 collections.Hashable to remain meaningful in the presence of the
2149 default hash implementation (object.__hash__), it is now possible
2150 to explicit block inheritance of hash by setting __hash__=None at
2151 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2152 level.
2153
Nick Coghlanb028f502008-07-13 14:52:36 +00002154- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2155 the parent module cannot be found while performing an absolute import.
2156 This means that an incorrectly defined __package__ attribute will
2157 now only prevent relative imports in that module rather than causing
2158 all imports from that module to fail.
2159
Nick Coghlan14ff9942008-07-08 14:21:42 +00002160- Issue #2517: Allow unicode messages in Exceptions again by correctly

2162 new-style classes.
2163
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002164- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

Georg Brandl5cc774e2008-06-11 20:28:06 +00002631 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002632
2633 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00002693- Issue #1631171: Re-implement the 'warnings' module in C (the
2694 original Python code has been kept as backup). This will allow for
2695 using the 'warning's machinery in such places as the parser where
2696 use of pure Python code is not possible. Both the ``showarning()``
2697 and ``formatwarning()`` gain an optional 'line' argument which is
2698 not called by default for backwards-compatibility reasons. Setting
2699 ``warnings.showwarning()`` to an implementation that lacks support
2700 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002763- Issue #2550: The approach used by client/server code for obtaining
2764 ports to listen on in network-oriented tests has been refined in an
2765 effort to facilitate running multiple instances of the entire
2766 regression test suite in parallel without issue.
2767 test_support.bind_port() has been fixed such that it will always
2768 return a unique port -- which wasn't always the case with the
2769 previous implementation, especially if socket options had been set
2770 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2771 new implementation of bind_port() will actually raise an exception
2772 if it is passed an AF_INET/SOCK_STREAM socket with either the
2773 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2774 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2775 the socket it's been passed. This currently only applies to
2776 Windows. This option prevents any other sockets from binding to the
2777 host/port we've bound to, thus removing the possibility of the
2778 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2779 when a second SOCK_STREAM socket binds and accepts to a host/port
2780 that's already been bound by another socket. The optional preferred
2781 port parameter to bind_port() has been removed. Under no
2782 circumstances should tests be hard coding ports!
2783
2784 test_support.find_unused_port() has also been introduced, which will
2785 pass a temporary socket object to bind_port() in order to obtain an
2786 unused port. The temporary socket object is then closed and
2787 deleted, and the port is returned. This method should only be used
2788 for obtaining an unused port in order to pass to an external program
2789 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2790 a parameter to a server-oriented class that doesn't give you direct
2791 access to the underlying socket used.
2792
2793 Finally, test_support.HOST has been introduced, which should be used
2794 for the host argument of any relevant socket calls (i.e. bind and
2795 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002796
2797 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002798 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002799 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2800 test_asynchat and test_socket_ssl.
2801
Georg Brandl3ee81df2008-05-17 18:14:43 +00002802 It is now possible for multiple instances of the regression test
2803 suite to run in parallel without issue.

Facundo Batistac54aec12008-03-08 16:50:27 +00002986- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
Georg Brandl3ee81df2008-05-17 18:14:43 +00002987 optional: it defaults to the traceback of the exception that is
2988 currently being handled (is mandatory to be in the middle of an
2989 exception, otherwise it raises ValueError).

Thomas Hellerf3c05592008-03-05 15:34:29 +00003004- Issue #1872: The struct module typecode for _Bool has been changed
3005 from 't' to '?'.
3006
Thomas Heller78b8f442008-03-05 14:53:39 +00003007- The bundled libffi copy is now in sync with the recently released
3008 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003009 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
3010 files are used. On all linux systems the --with-system-ffi
3011 configure option defaults to "yes".

3071
Fred Drakea8ee94b2008-03-01 02:45:07 +00003072- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003073 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003075- Issue #2067: file.__exit__() now calls subclasses' close() method.
3076
3077- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003078
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003079- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003080 issue 215555 for a discussion.
3081
Eric Smitha73fbe72008-02-23 03:09:44 +00003082- Added the future_builtins module, which contains hex() and oct().
3083 These are the PEP 3127 version of these functions, designed to be
3084 compatible with the hex() and oct() builtins from Python 3.0. They
3085 differ slightly in their output formats from the existing, unchanged
3086 Python 2.6 builtins. The expected usage of the future_builtins
3087 module is:
3088 from future_builtins import hex, oct
3089
Eric Smith7ef40bf2008-02-20 23:34:22 +00003090- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3091 exponents for exponents with absolute value < 100. Follows C99
3092 standard. This is a change on Windows, which would use 3 digits.
3093 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3094 so that any alterations it does to the resulting string will be
3095 available in stringlib/formatter.h (for float.__format__).
3096
Eric Smith5a3c1352008-02-19 13:21:56 +00003097- Implemented PEP 3101, Advanced String Formatting. This adds a new
3098 builtin format(); a format() method for str and unicode; a
3099 __format__() method to object, str, unicode, int, long, float, and
3100 datetime; the class string.Formatter; and the C API
3101 PyObject_Format().
3102
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103- Fixed several potential crashes, all caused by specially crafted
3104 __del__ methods exploiting objects in temporarily inconsistent
3105 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003106
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003107- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003108 prevent a possible crash: an Abstract Base Class would try to access
3109 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003110
Georg Brandl3ee81df2008-05-17 18:14:43 +00003111- Fixed repr() and str() of complex numbers with infinity or nan as
3112 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003113
Georg Brandl3ee81df2008-05-17 18:14:43 +00003114- Clear all free lists during a gc.collect() of the highest generation
3115 in order to allow pymalloc to free more arenas. Python may give back
3116 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003117
Georg Brandl3ee81df2008-05-17 18:14:43 +00003118- Issue #2045: Fix an infinite recursion triggered when printing a
3119 subclass of collections.defaultdict, if its default_factory is set
3120 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003121
Christian Heimesf75dbef2008-02-08 00:11:31 +00003122- Fixed a minor memory leak in dictobject.c. The content of the free
3123 list was not freed on interpreter shutdown.
3124
Georg Brandl5a7eca12010-03-21 19:29:04 +00003125- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003127
Georg Brandl3ee81df2008-05-17 18:14:43 +00003128- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3129 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003130 to compact the internal free lists of pre-allocted ints and floats.
3131
Georg Brandl3ee81df2008-05-17 18:14:43 +00003132- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3133 calls. Python expected the return type int but the fork familie
3134 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3137 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003138
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3140 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003141

Georg Brandl3ee81df2008-05-17 18:14:43 +00003145- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3146 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003147
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- Patch #1473257: generator objects gain a gi_code attribute. This is
3149 the same object as the func_code attribute of the function that
3150 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003151
Georg Brandl3ee81df2008-05-17 18:14:43 +00003152- Issue #1920: "while 0" statements were completely removed by the
3153 compiler, even in the presence of an "else" clause, which is
3154 supposed to be run when the condition is false. Now the compiler
3155 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003156
Guido van Rossumeead05f2008-01-24 18:21:02 +00003157- A few crashers fixed: weakref_in_del.py (issue #1377858);
3158 loosing_dict_ref.py (issue #1303614, test67.py);
3159 borrowed_ref_[34].py (not in tracker).
3160
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003161- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003162 suppressed while an extension is loaded by calling SetErrorMode in
3163 dynload_win.c. The error is still reported properly.
3164
Georg Brandl3ee81df2008-05-17 18:14:43 +00003165- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003166 several extension methods and modules do not work without unicode
3167 support.
3168
Georg Brandl26543b12008-01-21 18:36:51 +00003169- Issue #1882: when compiling code from a string, encoding cookies in the
3170 second line of code were not always recognized correctly.
3171
Georg Brandl14404b62008-01-19 19:27:05 +00003172- Issue #1679: "0x" was taken as a valid integer literal.
3173
Georg Brandl6caad7d2008-01-26 14:19:22 +00003174- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003175 added.
3176
Christian Heimesc94e2b52008-01-14 04:13:37 +00003177- sys.float_info / PyFloat_GetInfo: The floating point information
3178 object was converted from a dict to a specialized structseq object.
3179
Georg Brandl3ee81df2008-05-17 18:14:43 +00003180- Patch #1816: Added sys.flags structseq. It exposes the status of
3181 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003182
Georg Brandl3ee81df2008-05-17 18:14:43 +00003183- Objects/structseq.c: Implemented new structseq representation. The
3184 patch makes structseqs (e.g. the return value of os.stat) more
3185 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003186
Georg Brandl3ee81df2008-05-17 18:14:43 +00003187- Patch #1700288: added a type attribute cache that caches method

3196 envvar and sys.dont_write_bytecode attribute. All these can be set
3197 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003198
Georg Brandl3ee81df2008-05-17 18:14:43 +00003199- Improve some exception messages when Windows fails to load an
3200 extension module. Now we get for example '%1 is not a valid Win32
3201 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003202

Christian Heimes0a8143f2007-12-18 23:22:54 +00003208- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003209 and INF. float("nan"), float("inf") and float("-inf") now work on
3210 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003211
Georg Brandl3ee81df2008-05-17 18:14:43 +00003212- Compiler now generates simpler and faster code for dictionary
3213 literals. The oparg for BUILD_MAP now indicates an estimated
3214 dictionary size. There is a new opcode, STORE_MAP, for adding
3215 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003244- Patch #1739468: Directories and zipfiles containing a __main__.py
3245 file can now be directly executed by passing their name to the
3246 interpreter. The directory/zipfile is automatically inserted as the
3247 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003249- Issue #1265: Fix a problem with sys.settrace, if the tracing
3250 function uses a generator expression when at the same time the
3251 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003252
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003253- sets and frozensets now have an isdisjoint() method.

3258
Georg Brandl5a7eca12010-03-21 19:29:04 +00003259- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3261 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003262
Georg Brandl3ee81df2008-05-17 18:14:43 +00003263- Issue #1686386: Tuple's tp_repr did not take into account the
3264 possibility of having a self-referential tuple, which is possible
3265 from C code. Nor did object's tp_str consider that a type's tp_str
3266 could do something that could lead to an inifinite recursion.
3267 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3268 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003269
Georg Brandl3ee81df2008-05-17 18:14:43 +00003270- Issue #1164: It was possible to trigger deadlock when using the
3271 'print' statement to write to a file since the GIL was not released
3272 as needed. Now PyObject_Print() does the right thing along with
3273 various tp_print implementations of the built-in types and those in
3274 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003275
Georg Brandl3ee81df2008-05-17 18:14:43 +00003276- Issue #1147: Exceptions were directly allowing string exceptions in
3277 their throw() method even though string exceptions no longer
3278 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003279
Georg Brandl3ee81df2008-05-17 18:14:43 +00003280- Issue #1096: Prevent a segfault from getting the repr of a very
3281 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003282
Brett Cannon1e534b52007-09-07 04:18:30 +00003283- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284 PyObject_Call() never calling back out to Python code to trigger
3285 recursion depth updates/checks. Required the creation of a static
3286 RuntimeError instance in case normalizing an exception put the
3287 recursion check value past its limit. Fixes crashers
3288 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003289

Neal Norwitz0ac60192007-05-27 04:08:54 +00003303- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003304 __*__ attributes. (Some already existed, e.g., __doc__ and
3305 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003306
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003307- Add -3 option to the interpreter to warn about features that are
3308 deprecated and will be changed/removed in Python 3.0.
3309
Georg Brandl2134e752007-05-21 20:34:16 +00003310- Patch #1686487: you can now pass any mapping after '**' in function
3311 calls.
3312
Collin Winter62903052007-05-18 23:11:24 +00003313- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003314 "except E as target:". This is to provide forwards compatibility
3315 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003316
Brett Cannon229cee22007-05-05 01:34:02 +00003317- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003319- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003320 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003321
Vinay Sajip8549ce32007-05-06 17:53:37 +00003322- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003323 setting a plain string, ie don't expand to single letter identifiers.
3324
Raymond Hettinger13936692007-04-11 18:40:58 +00003325- Request #1191699: Slices can now be pickled.
3326
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003327- Request #1193128: str.translate() now allows a None argument for
3328 translations that only remove characters without re-mapping the
3329 remaining characters.
3330
Georg Brandl5cb76c12007-03-21 09:00:39 +00003331- Patch #1682205: a TypeError while unpacking an iterable is no longer
3332 masked by a generic one with the message "unpack non-sequence".
3333
Neal Norwitzaa754b72007-03-21 06:39:48 +00003334- Remove unused file Python/fmod.c.
3335
Guido van Rossum143b5642007-03-23 04:58:42 +00003336- Bug #1683368: The object.__init__() and object.__new__() methods are
3337 now stricter in rejecting excess arguments. The only time when
3338 either allows excess arguments is when it is not overridden and the
3339 other one is. For backwards compatibility, when both are
3340 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003341 warning later). Also, type.__init__() insists on the same signature
3342 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003343
Georg Brandl3ee81df2008-05-17 18:14:43 +00003344- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3345 object to complex using its __complex__() method before falling back
3346 to the __float__() method. Therefore, the functions in the cmath
3347 module now can operate on objects that define a __complex__()
3348 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003349
Georg Brandl3ee81df2008-05-17 18:14:43 +00003350- Patch #1623563: allow __class__ assignment for classes with
3351 __slots__. The old and the new class are still required to have the
3352 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003353

3358 ``object.__reduce_ex__()`` is called with an object that is faking
3359 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003360
Georg Brandl3ee81df2008-05-17 18:14:43 +00003361- Patch #1680015: Don't modify __slots__ tuple if it contains an

3365
Georg Brandl7b9c5552007-03-12 14:30:05 +00003366- Bug #1678647: write a newline after printing an exception in any
3367 case, even when converting the value to a string failed.
3368
Georg Brandl871f1bc2007-03-12 13:17:36 +00003369- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003370 its argument, if it exists. If not, it will work like before. This
3371 allows customizing the output of dir() in the presence of a
3372 __getattr__().

3375 self-recursive reload() calls (as reported by bug #742342).
3376

Georg Brandl3ee81df2008-05-17 18:14:43 +00003380- Patch #1491866: change the complex() constructor to allow
3381 parthensized forms. This means complex(repr(x)) now works instead of
3382 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003383
Georg Brandlaa2321b2007-03-07 00:40:28 +00003384- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003385 makes the filenames the warning module prints much more sensible
3386 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003387

3389 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003390 variable is given, but break into the interactive interpreter just
3391 like on other exceptions or normal program exit.

3397 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003398
Georg Brandl0fca97a2007-03-05 22:28:08 +00003399- Patch #1674228: when assigning a slice (old-style), check for the
3400 sq_ass_slice instead of the sq_slice slot.
3401
Georg Brandl3ee81df2008-05-17 18:14:43 +00003402- When printing an unraisable error, don't print exceptions. before
3403 the name. This duplicates the behavior whening normally printing
3404 exceptions.

4032 -- the failure just occurred later, with a more cumbersome
4033 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004314- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4315 with RFC 3207 and forgets any knowledge obtained from the server not
4316 obtained from the TLS negotiation itself. Patch contributed by Bill
4317 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004318
Georg Brandl3ee81df2008-05-17 18:14:43 +00004319- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004320 that the SMTP.starttls() caller no longer needs to call ehlo()
4321 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004322 does not claim to support starttls. Adds the
4323 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4324 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004378- itertools.chain() now has an alternate constructor,

4404 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4405 silently miscode subclasses of those types. Now, it raises a
4406 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004407

Georg Brandl3ee81df2008-05-17 18:14:43 +00004422 time so that opening a database previously created with the DB_DUP
4423 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4424 opens. Specifically: dictionary assignment to a DB object will
4425 replace all values for a given key when the database allows
4426 duplicate values. DB users should use DB.put(k, v) when they want
4427 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004428

4434 characters with ASCII value less than 32. Also, it correctly quotes
4435 dots only if they occur on a single line, as opposed to the previous
4436 behavior of quoting dots if they are the second character of any
4437 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004438
Georg Brandla47337f2007-03-13 12:34:25 +00004439- Bug #1622896: fix a rare corner case where the bz2 module raised an

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004706- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004707 periodic threadstate and signal checking in tight loops. By
4708 default, this option is turned-off. It should only be enabled in
4709 debugged, performance critical applications.

4760-----
4761
Georg Brandl3ee81df2008-05-17 18:14:43 +00004762- Unified naming convention for free lists and their limits. All free
4763 lists in Object/ are named ``free_list``, the counter ``numfree``
4764 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4765 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004766
Georg Brandl3ee81df2008-05-17 18:14:43 +00004767- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4768 to ``PyTuple_SetItem``, it can be used to populate a brand new
4769 frozenset; but it does not steal a reference to the added item.

4781
Georg Brandl3ee81df2008-05-17 18:14:43 +00004782- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4783 of w# format code incorrectly truncated the length to an int, even
4784 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4785 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004786
Georg Brandl3ee81df2008-05-17 18:14:43 +00004787- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4807
4808- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4809 outside of pystate.c and should not be necessary.
4810
Georg Brandl3ee81df2008-05-17 18:14:43 +00004811- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4812 absolute imports. In earlier versions they might have used relative
4813 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004814
Georg Brandl3ee81df2008-05-17 18:14:43 +00004815- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4816 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004817
Georg Brandl3ee81df2008-05-17 18:14:43 +00004818- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004843- Removed the macfs module. It had been deprecated since Python 2.5.
4844 This lead to the deprecation of macostools.touched() as it relied
4845 solely on macfs and was a no-op under OS X.
