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

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

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>`_.

1727
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001728- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1729 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1730 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1731 ``printf`` function, whereas PyString_FromFormat has an independent
1732 implementation and uses "%zd" on all platforms for size_t values.
1733 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +00001754 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1755 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1757 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1758 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001894What's New in Python 2.6 beta 3?
1895================================
1896
Barry Warsaw07a4a382008-08-21 01:15:08 +00001897*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001898
1899Core and Builtins
1900-----------------
1901
Guido van Rossumf8402962008-08-20 15:01:50 +00001902- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1903 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1904 extensions do not automatically benefit from the class attribute
1905 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1906 to their tp_flags field if they care. This is a backwards
1907 compatibility feature; in 3.0, all types will use the cache by
1908 default.
1909
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001910- Keyword arguments can now follow starred arguments. (``f(a, *args,
1911 keyword=23)`` is now valid syntax.)
1912
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001913- ctypes function pointers that are COM methods have a boolean True
1914 value again.
1915
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001916- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1917 by denying s# to parse objects that have a releasebuffer procedure,
1918 and introducing s*.
1919
Georg Brandl1e13ea92008-08-11 09:07:59 +00001920- Issue #3537: Fix an assertion failure when an empty but presized dict
1921 object was stored in the freelist.
1922
Mark Dickinsonb6467572008-08-04 21:30:09 +00001923- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1924 ValueError consistently across platforms.
1925
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001926- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1927 (64bit Unix, for example), unichr() would truncate its argument and return
1928 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1929
Neal Norwitze7d8be82008-07-31 17:17:14 +00001930- Apply security patches from Apple.
1931
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001932- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1933 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1934
Antoine Pitrou92f82162008-07-25 22:22:08 +00001935- Issue #1819: function calls with several named parameters are now on
1936 average 35% faster (as measured by pybench).
1937
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001938- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1939 the python debugger steps into a class statement: the free variables (local
1940 variables defined in an outer scope) would be deleted from the outer scope.
1941
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001942- Issue #2620: Overflow checking when allocating or reallocating memory
1943 was not always being done properly in some python types and extension
1944 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1945 all been updated to perform better checks and places in the code that
1946 would previously leak memory on the error path when such an allocation
1947 failed have been fixed.
1948
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001949Library
1950-------
1951
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001952- Issue #3612: Added some missing basic types in ctypes.wintypes.
1953
Benjamin Petersone977ad42008-08-20 01:42:01 +00001954- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1955 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1956
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001957- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1958 version reported by these tools does not necessarily follow the python
1959 version numbering scheme, so the module is less strict when parsing it.
1960
Nick Coghlanf70385a2008-08-18 12:42:46 +00001961- Issue #2235: Added Py3k warnings for types which will become unhashable
1962 under the stricter __hash__ inheritance rules in 3.0. Several types
1963 which did not meet the rules for hash invariants and were already
1964 unhashable in 3.0 have now been explicitly flagged as unhashable in
1965 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1966 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1967
Brett Cannon88f801d2008-08-18 00:46:22 +00001968- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1969 imported into the module but exposed as part of the module's API.
1970
Brett Cannon7b96f072008-08-18 00:41:11 +00001971- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1972
Brett Cannon46225e72008-08-18 00:36:52 +00001973- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1974
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001975- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1976
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001977- Issue #3575: Incremental decoder's decode function now takes bytearray
1978 by using 's*' instead of 't#'.
1979
Jesus Cea585ad8a2009-07-02 15:37:21 +00001980- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001981 fails unicode conversion on 2nd parameter. (windows only)
1982
Facundo Batista94f243a2008-08-17 03:38:39 +00001983- Issue 2464. urllib2 now supports a malformation in the URL received
1984 in a redirect.
1985
Brett Cannonabe423e2008-08-16 21:47:07 +00001986- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001987 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001988
Facundo Batistaeb90b782008-08-16 14:44:07 +00001989- Issue #2776: fixed small issue when handling an URL with double slash
1990 after a 302 response in the case of not going through a proxy.
1991
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001992- Issue #2676: in the email package, content-type parsing was hanging on
1993 pathological input because of quadratic or exponential behaviour of a
1994 regular expression.
1995
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001996- Issue #3476: binary buffered reading through the new "io" library is now
1997 thread-safe.
1998
Brett Cannonbf3157b2008-08-14 05:00:03 +00001999- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2000 since mimetools itself is deprecated. Because modules are cached, all
2001 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2002
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002003- Issue #3134: shutil referenced undefined WindowsError symbol.
2004
Robert Schuppenies14646332008-08-10 11:01:53 +00002005- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2006 menu entries were not deleted.
2007
Brett Cannon83e81842008-08-09 23:30:55 +00002008- Copied the implementation of reduce() to _functools.reduce() to have a
2009 version that did not raise a DeprecationWarning under -3.
2010
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002011- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2012 a MemoryError rather than silently stop the iteration.
2013
Guido van Rossum59ce9012008-08-09 14:55:34 +00002014- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2015 to _sre.compile() will now be rejected. This should not affect anybody
2016 since the re.compile() function never generates invalid re-bytecode.
2017
Skip Montanaroa032bf42008-08-08 22:52:51 +00002018- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2019 upon first access it can be automatically initialized from the csv file if
2020 it wasn't initialized during instantiation.
2021
Brett Cannon3aa2a492008-08-06 22:28:09 +00002022- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2023 the reload() built-in has been removed.
2024
Brett Cannon7e30b672008-08-04 21:52:25 +00002025- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002026 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2030 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2031 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002032
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002033- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2034 raised an AttributeError.
2035
Benjamin Peterson01a24322008-07-28 23:35:27 +00002036- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002037 asking for a specific length. This problem only affected files opened
2038 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002039
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002040- Issue #3449: Update decimal module to use most recent specification
2041 (v. 1.68) and tests (v. 2.58) from IBM.
2042
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002043- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2051
2052- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2053 invalid arguments.
2054
2055- Issue #3302: Fix several crashes when calling locale's gettext functions
2056 with None arguments.
2057
2058- Issue #3389: Allow resolving dotted names for handlers in logging
2059 configuration files.
2060
2061- Deprecate the sunaudio module for removal in Python 3.0.
2062
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002063- Issue #3394: zipfile.writestr sets external attributes when passed a
2064 file name rather than a ZipInfo instance, so files are extracted with
2065 mode 0600 rather than 000 under Unix.
2066
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002067- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2068 argument in python 2.5, this broke code that subclassed Popen to include its
2069 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2078
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002079- Issue #2235: the C API function PyObject_HashNotImplemented and its
2080 interaction with the tp_hash slot (added in 2.6b2) are now documented
2081
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002082- Issue #643841: The language reference now provides more detailed
2083 coverage of the lookup process for special methods. The disclaimers
2084 regarding lack of coverage of new-style classes have also been
2085 removed, since the coverage is now fairly reasonable.

2089================================
2090
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002091*Release date: 17-Jul-2008*

2094-----------------
2095
Georg Brandl3e483f62008-07-16 22:57:41 +00002096- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2097 its methods now allow for items objects that can be converted to
2098 an integer using operator.index().
2099
Mark Dickinson64b7e502008-07-16 09:40:03 +00002100- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2101 produced a ValueError instead of giving the correct float.
2102
Eric Smitha5fa5a22008-07-16 00:11:49 +00002103- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2104 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2105
Mark Dickinson7103aa42008-07-15 19:08:33 +00002106- Issue #3008: the float type has a new instance method 'float.hex'
2107 and a new class method 'float.fromhex' to convert floating-point
2108 numbers to and from hexadecimal strings, respectively.
2109
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002110- Issue #2235: __hash__ is once again inherited by default. To allow
2111 collections.Hashable to remain meaningful in the presence of the
2112 default hash implementation (object.__hash__), it is now possible
2113 to explicit block inheritance of hash by setting __hash__=None at
2114 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2115 level.
2116
Nick Coghlanb028f502008-07-13 14:52:36 +00002117- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2118 the parent module cannot be found while performing an absolute import.
2119 This means that an incorrectly defined __package__ attribute will
2120 now only prevent relative imports in that module rather than causing
2121 all imports from that module to fail.
2122
Nick Coghlan14ff9942008-07-08 14:21:42 +00002123- Issue #2517: Allow unicode messages in Exceptions again by correctly
2124 bypassing the instance dictionary when looking up __unicode__ on
2125 new-style classes.
2126
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002127- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2128 set to a custom object whose write() method happens to install
2129 another file in sys.stdout.

2133 another thread's dictionary.
2134
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002135- Issue #3004: Minor change to slice.indices(): the start and stop
2136 arguments are now treated identically, making the behaviour easier
2137 to describe and understand. For example, slice(None, -10,
2138 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2139 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2140 10, -1).
2141
Georg Brandl278fc502008-07-19 12:46:12 +00002142- Issue #3219: Calling a function with repeated keyword arguments,
2143 f(a=2, a=23), would not cause a syntax error. This was a regression
2144 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002594 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002595
2596 This is controlled by the configure argument ``--with-universal-archs``:
2597
2598 - ``--with-universal-archs=all``: install 4-way universal
2599
2600 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2601
2602 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2603

Georg Brandl3ee81df2008-05-17 18:14:43 +00002656- Issue #1631171: Re-implement the 'warnings' module in C (the
2657 original Python code has been kept as backup). This will allow for
2658 using the 'warning's machinery in such places as the parser where
2659 use of pure Python code is not possible. Both the ``showarning()``
2660 and ``formatwarning()`` gain an optional 'line' argument which is
2661 not called by default for backwards-compatibility reasons. Setting
2662 ``warnings.showwarning()`` to an implementation that lacks support
2663 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002688- The getpass module has been improved on Unix. It now uses /dev/tty
2689 by default and uses stderr instead of stdout. A GetPassWarning is
2690 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002718- Issue #2385: distutils.core.run_script() makes __file__ available,
2719 so the controlled environment will more closely mirror the typical
2720 script environment. This supports setup.py scripts that refer to
2721 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002726- Issue #2550: The approach used by client/server code for obtaining
2727 ports to listen on in network-oriented tests has been refined in an
2728 effort to facilitate running multiple instances of the entire
2729 regression test suite in parallel without issue.
2730 test_support.bind_port() has been fixed such that it will always
2731 return a unique port -- which wasn't always the case with the
2732 previous implementation, especially if socket options had been set
2733 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2734 new implementation of bind_port() will actually raise an exception
2735 if it is passed an AF_INET/SOCK_STREAM socket with either the
2736 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2737 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2738 the socket it's been passed. This currently only applies to
2739 Windows. This option prevents any other sockets from binding to the
2740 host/port we've bound to, thus removing the possibility of the
2741 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2742 when a second SOCK_STREAM socket binds and accepts to a host/port
2743 that's already been bound by another socket. The optional preferred
2744 port parameter to bind_port() has been removed. Under no
2745 circumstances should tests be hard coding ports!
2746
2747 test_support.find_unused_port() has also been introduced, which will
2748 pass a temporary socket object to bind_port() in order to obtain an
2749 unused port. The temporary socket object is then closed and
2750 deleted, and the port is returned. This method should only be used
2751 for obtaining an unused port in order to pass to an external program
2752 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2753 a parameter to a server-oriented class that doesn't give you direct
2754 access to the underlying socket used.
2755
2756 Finally, test_support.HOST has been introduced, which should be used
2757 for the host argument of any relevant socket calls (i.e. bind and
2758 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002759
2760 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002761 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002762 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2763 test_asynchat and test_socket_ssl.
2764
Georg Brandl3ee81df2008-05-17 18:14:43 +00002765 It is now possible for multiple instances of the regression test
2766 suite to run in parallel without issue.

3032Core and builtins
3033-----------------
3034
Fred Drakea8ee94b2008-03-01 02:45:07 +00003035- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003036 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003037
Georg Brandlad61bc82008-02-23 15:11:18 +00003038- Issue #2067: file.__exit__() now calls subclasses' close() method.
3039
3040- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003041
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003042- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003043 issue 215555 for a discussion.
3044
Eric Smitha73fbe72008-02-23 03:09:44 +00003045- Added the future_builtins module, which contains hex() and oct().
3046 These are the PEP 3127 version of these functions, designed to be
3047 compatible with the hex() and oct() builtins from Python 3.0. They
3048 differ slightly in their output formats from the existing, unchanged
3049 Python 2.6 builtins. The expected usage of the future_builtins
3050 module is:
3051 from future_builtins import hex, oct
3052
Eric Smith7ef40bf2008-02-20 23:34:22 +00003053- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3054 exponents for exponents with absolute value < 100. Follows C99
3055 standard. This is a change on Windows, which would use 3 digits.
3056 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3057 so that any alterations it does to the resulting string will be
3058 available in stringlib/formatter.h (for float.__format__).
3059
Eric Smith5a3c1352008-02-19 13:21:56 +00003060- Implemented PEP 3101, Advanced String Formatting. This adds a new
3061 builtin format(); a format() method for str and unicode; a
3062 __format__() method to object, str, unicode, int, long, float, and
3063 datetime; the class string.Formatter; and the C API
3064 PyObject_Format().
3065
Georg Brandl3ee81df2008-05-17 18:14:43 +00003066- Fixed several potential crashes, all caused by specially crafted
3067 __del__ methods exploiting objects in temporarily inconsistent
3068 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003069
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003070- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071 prevent a possible crash: an Abstract Base Class would try to access
3072 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003073
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074- Fixed repr() and str() of complex numbers with infinity or nan as
3075 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003076
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- Clear all free lists during a gc.collect() of the highest generation
3078 in order to allow pymalloc to free more arenas. Python may give back
3079 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003080
Georg Brandl3ee81df2008-05-17 18:14:43 +00003081- Issue #2045: Fix an infinite recursion triggered when printing a
3082 subclass of collections.defaultdict, if its default_factory is set
3083 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003084
Christian Heimesf75dbef2008-02-08 00:11:31 +00003085- Fixed a minor memory leak in dictobject.c. The content of the free
3086 list was not freed on interpreter shutdown.
3087
Georg Brandl5a7eca12010-03-21 19:29:04 +00003088- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003089 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003090
Georg Brandl3ee81df2008-05-17 18:14:43 +00003091- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3092 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003093 to compact the internal free lists of pre-allocted ints and floats.
3094
Georg Brandl3ee81df2008-05-17 18:14:43 +00003095- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3096 calls. Python expected the return type int but the fork familie
3097 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003098
Georg Brandl3ee81df2008-05-17 18:14:43 +00003099- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3100 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003101
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3103 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003104

Georg Brandl3ee81df2008-05-17 18:14:43 +00003108- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3109 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003110
Georg Brandl3ee81df2008-05-17 18:14:43 +00003111- Patch #1473257: generator objects gain a gi_code attribute. This is
3112 the same object as the func_code attribute of the function that
3113 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003114
Georg Brandl3ee81df2008-05-17 18:14:43 +00003115- Issue #1920: "while 0" statements were completely removed by the
3116 compiler, even in the presence of an "else" clause, which is
3117 supposed to be run when the condition is false. Now the compiler
3118 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003119
Guido van Rossumeead05f2008-01-24 18:21:02 +00003120- A few crashers fixed: weakref_in_del.py (issue #1377858);
3121 loosing_dict_ref.py (issue #1303614, test67.py);
3122 borrowed_ref_[34].py (not in tracker).
3123
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003124- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003125 suppressed while an extension is loaded by calling SetErrorMode in
3126 dynload_win.c. The error is still reported properly.
3127
Georg Brandl3ee81df2008-05-17 18:14:43 +00003128- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003129 several extension methods and modules do not work without unicode
3130 support.
3131
Georg Brandl26543b12008-01-21 18:36:51 +00003132- Issue #1882: when compiling code from a string, encoding cookies in the
3133 second line of code were not always recognized correctly.
3134
Georg Brandl14404b62008-01-19 19:27:05 +00003135- Issue #1679: "0x" was taken as a valid integer literal.
3136
Georg Brandl6caad7d2008-01-26 14:19:22 +00003137- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003138 added.
3139
Christian Heimesc94e2b52008-01-14 04:13:37 +00003140- sys.float_info / PyFloat_GetInfo: The floating point information
3141 object was converted from a dict to a specialized structseq object.
3142
Georg Brandl3ee81df2008-05-17 18:14:43 +00003143- Patch #1816: Added sys.flags structseq. It exposes the status of
3144 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003145
Georg Brandl3ee81df2008-05-17 18:14:43 +00003146- Objects/structseq.c: Implemented new structseq representation. The
3147 patch makes structseqs (e.g. the return value of os.stat) more
3148 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003149
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003172 and INF. float("nan"), float("inf") and float("-inf") now work on
3173 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003174
Georg Brandl3ee81df2008-05-17 18:14:43 +00003175- Compiler now generates simpler and faster code for dictionary
3176 literals. The oparg for BUILD_MAP now indicates an estimated
3177 dictionary size. There is a new opcode, STORE_MAP, for adding
3178 entries to the dictionary.

Georg Brandl5a7eca12010-03-21 19:29:04 +00003222- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003223 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3224 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003225
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226- Issue #1686386: Tuple's tp_repr did not take into account the
3227 possibility of having a self-referential tuple, which is possible
3228 from C code. Nor did object's tp_str consider that a type's tp_str
3229 could do something that could lead to an inifinite recursion.
3230 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3231 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003232
Georg Brandl3ee81df2008-05-17 18:14:43 +00003233- Issue #1164: It was possible to trigger deadlock when using the
3234 'print' statement to write to a file since the GIL was not released
3235 as needed. Now PyObject_Print() does the right thing along with
3236 various tp_print implementations of the built-in types and those in
3237 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003238
Georg Brandl3ee81df2008-05-17 18:14:43 +00003239- Issue #1147: Exceptions were directly allowing string exceptions in
3240 their throw() method even though string exceptions no longer
3241 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- Issue #1096: Prevent a segfault from getting the repr of a very
3244 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003245
Brett Cannon1e534b52007-09-07 04:18:30 +00003246- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003247 PyObject_Call() never calling back out to Python code to trigger
3248 recursion depth updates/checks. Required the creation of a static
3249 RuntimeError instance in case normalizing an exception put the
3250 recursion check value past its limit. Fixes crashers
3251 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003252
Georg Brandl3ee81df2008-05-17 18:14:43 +00003253- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003266- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003267 __*__ attributes. (Some already existed, e.g., __doc__ and
3268 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003269
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003270- Add -3 option to the interpreter to warn about features that are
3271 deprecated and will be changed/removed in Python 3.0.
3272
Georg Brandl2134e752007-05-21 20:34:16 +00003273- Patch #1686487: you can now pass any mapping after '**' in function
3274 calls.
3275
Collin Winter62903052007-05-18 23:11:24 +00003276- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277 "except E as target:". This is to provide forwards compatibility
3278 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003279
Brett Cannon229cee22007-05-05 01:34:02 +00003280- Deprecate BaseException.message as per PEP 352.
3281
Georg Brandl3ee81df2008-05-17 18:14:43 +00003282- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003283 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003285- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003286 setting a plain string, ie don't expand to single letter identifiers.
3287
Raymond Hettinger13936692007-04-11 18:40:58 +00003288- Request #1191699: Slices can now be pickled.
3289
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003290- Request #1193128: str.translate() now allows a None argument for
3291 translations that only remove characters without re-mapping the
3292 remaining characters.
3293
Georg Brandl5cb76c12007-03-21 09:00:39 +00003294- Patch #1682205: a TypeError while unpacking an iterable is no longer
3295 masked by a generic one with the message "unpack non-sequence".
3296
Neal Norwitzaa754b72007-03-21 06:39:48 +00003297- Remove unused file Python/fmod.c.
3298
Guido van Rossum143b5642007-03-23 04:58:42 +00003299- Bug #1683368: The object.__init__() and object.__new__() methods are
3300 now stricter in rejecting excess arguments. The only time when
3301 either allows excess arguments is when it is not overridden and the
3302 other one is. For backwards compatibility, when both are
3303 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003304 warning later). Also, type.__init__() insists on the same signature
3305 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003306
Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3308 object to complex using its __complex__() method before falling back
3309 to the __float__() method. Therefore, the functions in the cmath
3310 module now can operate on objects that define a __complex__()
3311 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003312
Georg Brandl3ee81df2008-05-17 18:14:43 +00003313- Patch #1623563: allow __class__ assignment for classes with
3314 __slots__. The old and the new class are still required to have the
3315 same slot names.

3321 ``object.__reduce_ex__()`` is called with an object that is faking
3322 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003323
Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Patch #1680015: Don't modify __slots__ tuple if it contains an

3328
Georg Brandl7b9c5552007-03-12 14:30:05 +00003329- Bug #1678647: write a newline after printing an exception in any
3330 case, even when converting the value to a string failed.
3331
Georg Brandl871f1bc2007-03-12 13:17:36 +00003332- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003333 its argument, if it exists. If not, it will work like before. This
3334 allows customizing the output of dir() in the presence of a
3335 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003343- Patch #1491866: change the complex() constructor to allow
3344 parthensized forms. This means complex(repr(x)) now works instead of
3345 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003346
Georg Brandlaa2321b2007-03-07 00:40:28 +00003347- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003348 makes the filenames the warning module prints much more sensible
3349 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003350

3352 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003353 variable is given, but break into the interactive interpreter just
3354 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003362- Patch #1674228: when assigning a slice (old-style), check for the
3363 sq_ass_slice instead of the sq_slice slot.
3364
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- When printing an unraisable error, don't print exceptions. before
3366 the name. This duplicates the behavior whening normally printing
3367 exceptions.

3995 -- the failure just occurred later, with a more cumbersome
3996 exception.

4209 partial fix for Bug #1574584.
4210
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004277- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4278 with RFC 3207 and forgets any knowledge obtained from the server not
4279 obtained from the TLS negotiation itself. Patch contributed by Bill
4280 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004281
Georg Brandl3ee81df2008-05-17 18:14:43 +00004282- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004283 that the SMTP.starttls() caller no longer needs to call ehlo()
4284 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004285 does not claim to support starttls. Adds the
4286 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4287 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004341- itertools.chain() now has an alternate constructor,

4356 contents before adding elements from the iterable. This fix brings
4357 the behavior into line with that for list.__init__().

4367 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4368 silently miscode subclasses of those types. Now, it raises a
4369 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004370

Georg Brandl3ee81df2008-05-17 18:14:43 +00004385 time so that opening a database previously created with the DB_DUP
4386 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4387 opens. Specifically: dictionary assignment to a DB object will
4388 replace all values for a given key when the database allows
4389 duplicate values. DB users should use DB.put(k, v) when they want
4390 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004391

4397 characters with ASCII value less than 32. Also, it correctly quotes
4398 dots only if they occur on a single line, as opposed to the previous
4399 behavior of quoting dots if they are the second character of any
4400 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004401

4723-----
4724
Georg Brandl3ee81df2008-05-17 18:14:43 +00004725- Unified naming convention for free lists and their limits. All free
4726 lists in Object/ are named ``free_list``, the counter ``numfree``
4727 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4728 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004729
Georg Brandl3ee81df2008-05-17 18:14:43 +00004730- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4731 to ``PyTuple_SetItem``, it can be used to populate a brand new
4732 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004733
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004734- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

4737 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4738 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004739
4740- Patch #1720595: add T_BOOL to the range of structmember types.
4741
4742- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4743 ``PyFloat_GetInfo()`` to the float API.
4744
Georg Brandl3ee81df2008-05-17 18:14:43 +00004745- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4746 of w# format code incorrectly truncated the length to an int, even
4747 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4748 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004749
Georg Brandl3ee81df2008-05-17 18:14:43 +00004750- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4751 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004752
Georg Brandl3ee81df2008-05-17 18:14:43 +00004753- PEP 3123: Provide forward compatibility with Python 3.0, while
4754 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4755 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004756
Georg Brandl3ee81df2008-05-17 18:14:43 +00004757- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4758 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004759
4760- Patch #1733960: Allow T_LONGLONG to accept ints.

4767
4768- Fix some leftovers from the conversion from int to Py_ssize_t
4769 (relevant to strings and sequences of more than 2**31 items).
4770
4771- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4772 outside of pystate.c and should not be necessary.
4773
Georg Brandl3ee81df2008-05-17 18:14:43 +00004774- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4775 absolute imports. In earlier versions they might have used relative
4776 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004777
Georg Brandl3ee81df2008-05-17 18:14:43 +00004778- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4779 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004780
Georg Brandl3ee81df2008-05-17 18:14:43 +00004781- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4782 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004788- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4789 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4790 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4791 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004792

Georg Brandl3ee81df2008-05-17 18:14:43 +00004806- Removed the macfs module. It had been deprecated since Python 2.5.
4807 This lead to the deprecation of macostools.touched() as it relied
4808 solely on macfs and was a no-op under OS X.
