12Core and Builtins
13-----------------
14
Victor Stinner082a65a2010-07-28 01:55:43 +000015- Issue #6213: Implement getstate() and setstate() methods of utf-8-sig and
16 utf-16 incremental encoders.
17
Ezio Melotti86e5e172010-07-03 05:34:39 +000018- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
19 start byte and the continuation byte(s) are now considered invalid, instead
20 of the number of bytes specified by the start byte.
21 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
22 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
23 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
24 Previous versions returned a single u'\ufffd'.
25
Benjamin Peterson8d649632010-06-22 19:21:33 +000026- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
27
Antoine Pitrou4595e512010-06-11 21:48:02 +000028- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
29 the interpreter with characters outside the Basic Multilingual Plane
30 (higher than 0x10000).
31
Mark Dickinson80068da2010-06-05 11:59:41 +000032- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsonb671c292010-06-05 12:15:35 +000033 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
34 arises from the "Overriding __eq__ blocks inheritance ..." warning
35 when turned into an exception: in this case the exception simply
36 gets ignored.
Mark Dickinson80068da2010-06-05 11:59:41 +000037
Benjamin Peterson85633362010-06-08 14:58:25 +000038- In the unicode/str.format(), raise a ValueError when indexes to arguments are
39 too large.
Benjamin Petersonc9719132010-06-07 22:27:32 +000040
Victor Stinnerc3e40e02010-05-25 22:40:38 +000041- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
42 and error handler, instead of writing to the C stderr file in utf-8
43
Brett Cannon7d006262010-05-20 18:41:08 +000044- Issue #7902: When using explicit relative import syntax, don't try
45 implicit relative import semantics.
46
Antoine Pitrou5de15942010-05-17 20:00:52 +000047- Issue #7079: Fix a possible crash when closing a file object while using
48 it from another thread. Patch by Daniel Stutzbach.
49
Mark Dickinsone02c9d22010-05-07 13:23:18 +000050- Issue #1533: fix inconsistency in range function argument
51 processing: any non-float non-integer argument is now converted to
52 an integer (if possible) using its __int__ method. Previously, only
53 small arguments were treated this way; larger arguments (those whose
54 __int__ was outside the range of a C long) would produce a TypeError.
55
Benjamin Petersonc218ce82010-04-16 22:43:53 +000056- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
57 passed to bytearray.
58
Benjamin Peterson8a488082010-04-06 21:55:35 +000059- Issue #8329: Don't return the same lists from select.select when no fds are
60 changed.

Victor Stinnerd156fa32010-03-21 13:32:31 +000068- Issue #7544: Preallocate thread memory before creating the thread to avoid
69 a fatal error in low memory condition.
70
Victor Stinner0217c952010-03-21 13:09:24 +000071- Issue #7820: The parser tokenizer restores all bytes in the right if
72 the BOM check fails.
73
Ronald Oussoren07466192010-04-18 14:34:22 +000074- Issue #7072: isspace(0xa0) is true on Mac OS X
75
Antoine Pitrou52ca5162010-05-21 17:22:43 +000076C-API
77-----
78
79- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
80 embedders of the interpreter to set sys.argv without also modifying
81 sys.path. This helps fix `CVE-2008-5983
82 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

89
Victor Stinner8243ddb2010-07-28 01:58:41 +000090- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
91 library. This means, for example, that opening an UTF-16 text file in append
92 mode doesn't add a BOM at the end of the file if the file isn't empty.
93
Gregory P. Smith034ec782010-07-25 20:00:02 +000094- Issue #3704: cookielib was not properly handling URLs with a / in the
95 parameters.
96
Victor Stinnera417db52010-07-24 01:12:54 +000097- Issue #4629: getopt raises an error if an argument ends with = whereas getopt
98 doesn't except a value (eg. --help= is rejected if getopt uses ['help='] long
99 options).

1596==========================
1597
1598*Release date: 04-Dec-2008*
1599
1600Core and Builtins
1601-----------------
1602
1603- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1604 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1605 instead of throwing a MemoryError.
1606
1607- Issue #4367: Python would segfault during compiling when the unicodedata
1608 module couldn't be imported and \N escapes were present.
1609
1610- Issue #4348: Some bytearray methods returned that didn't cause any change to
1611 the bytearray, returned the same bytearray instead of a copy.
1612
1613- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1614
1615- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1616
1617- Issue #4048: The parser module now correctly validates relative imports.
1618
1619- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1623 method does not return iterators for the 4th and 5th items.
1624
1625- Issue #4209: Enabling unicode_literals and the print_function in the same
1626 __future__ import didn't work.
1627
1628- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1629 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1630 really executed because I cannot move to such directory on win2k)
1631
1632- Issue #4069: When set.remove(element) is used with a set element, the element
1633 is temporarily replaced with an equivalent frozenset. But the eventual
1634 KeyError would always report the empty frozenset([]) as the missing key. Now
1635 it correctly refers to the initial element.
1636
1637- Fixed C99 style comments in several files. Python is now C89 compatible
1638 again.

1786
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001787- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1788 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1789 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1790 ``printf`` function, whereas PyString_FromFormat has an independent
1791 implementation and uses "%zd" on all platforms for size_t values.
1792 This makes a difference on win64, where ``printf`` needs "%Id" to display
1793 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001813 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1814 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1816 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1817 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00001887- Issue 3602: Moved test.test_support.catch_warning() to
1888 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1889 for catch_warnings() also led to an improvement in the raising of a
1890 DeprecationWarning related to warnings.warn_explicit().
1891
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001892- The deprecation warnings for the old camelCase threading API were removed.

1911
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001912- Issue #2975: When compiling several extension modules with Visual Studio 2008
1913 from the same python interpreter, some environment variables would grow
1914 without limit.
1915
Benjamin Peterson37346b22008-08-23 20:27:43 +00001916- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1923
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001924- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1932 wrapper for warnings.catch_warnings() that makes it easier to check
1933 that expected warning messages are being reported.
1934

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001953What's New in Python 2.6 beta 3?
1954================================
1955
Barry Warsaw07a4a382008-08-21 01:15:08 +00001956*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001957
1958Core and Builtins
1959-----------------
1960
Guido van Rossumf8402962008-08-20 15:01:50 +00001961- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1962 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1963 extensions do not automatically benefit from the class attribute
1964 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1965 to their tp_flags field if they care. This is a backwards
1966 compatibility feature; in 3.0, all types will use the cache by
1967 default.
1968
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001969- Keyword arguments can now follow starred arguments. (``f(a, *args,
1970 keyword=23)`` is now valid syntax.)
1971
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001972- ctypes function pointers that are COM methods have a boolean True
1973 value again.
1974
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001975- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1976 by denying s# to parse objects that have a releasebuffer procedure,
1977 and introducing s*.
1978
Georg Brandl1e13ea92008-08-11 09:07:59 +00001979- Issue #3537: Fix an assertion failure when an empty but presized dict
1980 object was stored in the freelist.
1981
Mark Dickinsonb6467572008-08-04 21:30:09 +00001982- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1983 ValueError consistently across platforms.
1984
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001985- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1986 (64bit Unix, for example), unichr() would truncate its argument and return
1987 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1988
Neal Norwitze7d8be82008-07-31 17:17:14 +00001989- Apply security patches from Apple.
1990
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001991- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1992 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1993
Antoine Pitrou92f82162008-07-25 22:22:08 +00001994- Issue #1819: function calls with several named parameters are now on
1995 average 35% faster (as measured by pybench).
1996
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001997- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1998 the python debugger steps into a class statement: the free variables (local
1999 variables defined in an outer scope) would be deleted from the outer scope.
2000
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002001- Issue #2620: Overflow checking when allocating or reallocating memory
2002 was not always being done properly in some python types and extension
2003 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2004 all been updated to perform better checks and places in the code that
2005 would previously leak memory on the error path when such an allocation
2006 failed have been fixed.
2007
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002008Library
2009-------
2010

2012
Benjamin Petersone977ad42008-08-20 01:42:01 +00002013- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2014 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2015
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002016- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2017 version reported by these tools does not necessarily follow the python
2018 version numbering scheme, so the module is less strict when parsing it.
2019
Nick Coghlanf70385a2008-08-18 12:42:46 +00002020- Issue #2235: Added Py3k warnings for types which will become unhashable
2021 under the stricter __hash__ inheritance rules in 3.0. Several types
2022 which did not meet the rules for hash invariants and were already
2023 unhashable in 3.0 have now been explicitly flagged as unhashable in
2024 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2025 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2026
Brett Cannon88f801d2008-08-18 00:46:22 +00002027- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2035
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002036- Issue #3575: Incremental decoder's decode function now takes bytearray
2037 by using 's*' instead of 't#'.
2038
Jesus Cea585ad8a2009-07-02 15:37:21 +00002039- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002040 fails unicode conversion on 2nd parameter. (windows only)
2041
Facundo Batista94f243a2008-08-17 03:38:39 +00002042- Issue 2464. urllib2 now supports a malformation in the URL received
2043 in a redirect.
2044
Brett Cannonabe423e2008-08-16 21:47:07 +00002045- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002046 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002047
Facundo Batistaeb90b782008-08-16 14:44:07 +00002048- Issue #2776: fixed small issue when handling an URL with double slash
2049 after a 302 response in the case of not going through a proxy.
2050
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002051- Issue #2676: in the email package, content-type parsing was hanging on
2052 pathological input because of quadratic or exponential behaviour of a
2053 regular expression.
2054
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002055- Issue #3476: binary buffered reading through the new "io" library is now
2056 thread-safe.
2057
Brett Cannonbf3157b2008-08-14 05:00:03 +00002058- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2059 since mimetools itself is deprecated. Because modules are cached, all
2060 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2061
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002062- Issue #3134: shutil referenced undefined WindowsError symbol.
2063
Robert Schuppenies14646332008-08-10 11:01:53 +00002064- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2065 menu entries were not deleted.
2066
Brett Cannon83e81842008-08-09 23:30:55 +00002067- Copied the implementation of reduce() to _functools.reduce() to have a
2068 version that did not raise a DeprecationWarning under -3.
2069
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002070- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2071 a MemoryError rather than silently stop the iteration.
2072
Guido van Rossum59ce9012008-08-09 14:55:34 +00002073- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2074 to _sre.compile() will now be rejected. This should not affect anybody
2075 since the re.compile() function never generates invalid re-bytecode.
2076
Skip Montanaroa032bf42008-08-08 22:52:51 +00002077- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

2082 the reload() built-in has been removed.
2083
Brett Cannon7e30b672008-08-04 21:52:25 +00002084- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002085 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002096 asking for a specific length. This problem only affected files opened
2097 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002098

2124 mode 0600 rather than 000 under Unix.
2125
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002126- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2158
Mark Dickinson64b7e502008-07-16 09:40:03 +00002159- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2160 produced a ValueError instead of giving the correct float.
2161
Eric Smitha5fa5a22008-07-16 00:11:49 +00002162- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2163 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2164
Mark Dickinson7103aa42008-07-15 19:08:33 +00002165- Issue #3008: the float type has a new instance method 'float.hex'

2170 collections.Hashable to remain meaningful in the presence of the
2171 default hash implementation (object.__hash__), it is now possible
2172 to explicit block inheritance of hash by setting __hash__=None at
2173 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2174 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00002176- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2177 the parent module cannot be found while performing an absolute import.
2178 This means that an incorrectly defined __package__ attribute will
2179 now only prevent relative imports in that module rather than causing
2180 all imports from that module to fail.

2193
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002194- Issue #3004: Minor change to slice.indices(): the start and stop
2195 arguments are now treated identically, making the behaviour easier
2196 to describe and understand. For example, slice(None, -10,
2197 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2198 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2199 10, -1).

2242 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002243 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00002653 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002654
2655 This is controlled by the configure argument ``--with-universal-archs``:
2656

2658
2659 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2660
2661 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2662
2663 This option should be used in combination with ``--enable-universalsdk=``.

2702 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002703
Christian Heimese74c8f22008-04-19 02:23:57 +00002704- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002715- Issue #1631171: Re-implement the 'warnings' module in C (the
2716 original Python code has been kept as backup). This will allow for
2717 using the 'warning's machinery in such places as the parser where
2718 use of pure Python code is not possible. Both the ``showarning()``
2719 and ``formatwarning()`` gain an optional 'line' argument which is
2720 not called by default for backwards-compatibility reasons. Setting
2721 ``warnings.showwarning()`` to an implementation that lacks support
2722 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002785- Issue #2550: The approach used by client/server code for obtaining
2786 ports to listen on in network-oriented tests has been refined in an
2787 effort to facilitate running multiple instances of the entire
2788 regression test suite in parallel without issue.
2789 test_support.bind_port() has been fixed such that it will always
2790 return a unique port -- which wasn't always the case with the
2791 previous implementation, especially if socket options had been set
2792 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2793 new implementation of bind_port() will actually raise an exception
2794 if it is passed an AF_INET/SOCK_STREAM socket with either the
2795 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2796 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2797 the socket it's been passed. This currently only applies to
2798 Windows. This option prevents any other sockets from binding to the
2799 host/port we've bound to, thus removing the possibility of the
2800 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2801 when a second SOCK_STREAM socket binds and accepts to a host/port
2802 that's already been bound by another socket. The optional preferred
2803 port parameter to bind_port() has been removed. Under no
2804 circumstances should tests be hard coding ports!
2805
2806 test_support.find_unused_port() has also been introduced, which will
2807 pass a temporary socket object to bind_port() in order to obtain an
2808 unused port. The temporary socket object is then closed and
2809 deleted, and the port is returned. This method should only be used
2810 for obtaining an unused port in order to pass to an external program
2811 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2812 a parameter to a server-oriented class that doesn't give you direct
2813 access to the underlying socket used.
2814
2815 Finally, test_support.HOST has been introduced, which should be used
2816 for the host argument of any relevant socket calls (i.e. bind and
2817 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002818
2819 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002820 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002821 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2822 test_asynchat and test_socket_ssl.
2823
Georg Brandl3ee81df2008-05-17 18:14:43 +00002824 It is now possible for multiple instances of the regression test
2825 suite to run in parallel without issue.

3093
Fred Drakea8ee94b2008-03-01 02:45:07 +00003094- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003095 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003097- Issue #2067: file.__exit__() now calls subclasses' close() method.
3098
3099- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003100
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003101- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003102 issue 215555 for a discussion.
3103
Eric Smitha73fbe72008-02-23 03:09:44 +00003104- Added the future_builtins module, which contains hex() and oct().
3105 These are the PEP 3127 version of these functions, designed to be
3106 compatible with the hex() and oct() builtins from Python 3.0. They
3107 differ slightly in their output formats from the existing, unchanged
3108 Python 2.6 builtins. The expected usage of the future_builtins
3109 module is:
3110 from future_builtins import hex, oct
3111
Eric Smith7ef40bf2008-02-20 23:34:22 +00003112- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3113 exponents for exponents with absolute value < 100. Follows C99
3114 standard. This is a change on Windows, which would use 3 digits.
3115 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3116 so that any alterations it does to the resulting string will be
3117 available in stringlib/formatter.h (for float.__format__).
3118
Eric Smith5a3c1352008-02-19 13:21:56 +00003119- Implemented PEP 3101, Advanced String Formatting. This adds a new
3120 builtin format(); a format() method for str and unicode; a
3121 __format__() method to object, str, unicode, int, long, float, and
3122 datetime; the class string.Formatter; and the C API
3123 PyObject_Format().
3124
Georg Brandl3ee81df2008-05-17 18:14:43 +00003125- Fixed several potential crashes, all caused by specially crafted
3126 __del__ methods exploiting objects in temporarily inconsistent
3127 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003128
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003129- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130 prevent a possible crash: an Abstract Base Class would try to access
3131 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003132
Georg Brandl3ee81df2008-05-17 18:14:43 +00003133- Fixed repr() and str() of complex numbers with infinity or nan as
3134 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Clear all free lists during a gc.collect() of the highest generation
3137 in order to allow pymalloc to free more arenas. Python may give back
3138 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003139
Georg Brandl3ee81df2008-05-17 18:14:43 +00003140- Issue #2045: Fix an infinite recursion triggered when printing a
3141 subclass of collections.defaultdict, if its default_factory is set
3142 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003143
Christian Heimesf75dbef2008-02-08 00:11:31 +00003144- Fixed a minor memory leak in dictobject.c. The content of the free
3145 list was not freed on interpreter shutdown.
3146
Georg Brandl5a7eca12010-03-21 19:29:04 +00003147- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003149
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3151 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003152 to compact the internal free lists of pre-allocted ints and floats.
3153
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3155 calls. Python expected the return type int but the fork familie
3156 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003157
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3159 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3162 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003163

Georg Brandl3ee81df2008-05-17 18:14:43 +00003167- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3168 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003169
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170- Patch #1473257: generator objects gain a gi_code attribute. This is
3171 the same object as the func_code attribute of the function that
3172 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003173
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174- Issue #1920: "while 0" statements were completely removed by the
3175 compiler, even in the presence of an "else" clause, which is
3176 supposed to be run when the condition is false. Now the compiler
3177 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003178
Guido van Rossumeead05f2008-01-24 18:21:02 +00003179- A few crashers fixed: weakref_in_del.py (issue #1377858);
3180 loosing_dict_ref.py (issue #1303614, test67.py);
3181 borrowed_ref_[34].py (not in tracker).
3182
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003183- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003184 suppressed while an extension is loaded by calling SetErrorMode in
3185 dynload_win.c. The error is still reported properly.
3186
Georg Brandl3ee81df2008-05-17 18:14:43 +00003187- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003188 several extension methods and modules do not work without unicode
3189 support.
3190
Georg Brandl26543b12008-01-21 18:36:51 +00003191- Issue #1882: when compiling code from a string, encoding cookies in the
3192 second line of code were not always recognized correctly.
3193
Georg Brandl14404b62008-01-19 19:27:05 +00003194- Issue #1679: "0x" was taken as a valid integer literal.
3195
Georg Brandl6caad7d2008-01-26 14:19:22 +00003196- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003197 added.
3198
Christian Heimesc94e2b52008-01-14 04:13:37 +00003199- sys.float_info / PyFloat_GetInfo: The floating point information
3200 object was converted from a dict to a specialized structseq object.
3201
Georg Brandl3ee81df2008-05-17 18:14:43 +00003202- Patch #1816: Added sys.flags structseq. It exposes the status of
3203 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003204
Georg Brandl3ee81df2008-05-17 18:14:43 +00003205- Objects/structseq.c: Implemented new structseq representation. The
3206 patch makes structseqs (e.g. the return value of os.stat) more
3207 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003208
Georg Brandl3ee81df2008-05-17 18:14:43 +00003209- Patch #1700288: added a type attribute cache that caches method
3210 accesses, resulting in speedups in heavily object-oriented code.

3216
Georg Brandl3ee81df2008-05-17 18:14:43 +00003217- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3218 envvar and sys.dont_write_bytecode attribute. All these can be set
3219 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003220
Georg Brandl3ee81df2008-05-17 18:14:43 +00003221- Improve some exception messages when Windows fails to load an
3222 extension module. Now we get for example '%1 is not a valid Win32
3223 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003224

3228 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003229
Christian Heimes0a8143f2007-12-18 23:22:54 +00003230- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003231 and INF. float("nan"), float("inf") and float("-inf") now work on
3232 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003233
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234- Compiler now generates simpler and faster code for dictionary

Georg Brandl3ee81df2008-05-17 18:14:43 +00003285- Issue #1686386: Tuple's tp_repr did not take into account the
3286 possibility of having a self-referential tuple, which is possible
3287 from C code. Nor did object's tp_str consider that a type's tp_str
3288 could do something that could lead to an inifinite recursion.
3289 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3290 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003306 PyObject_Call() never calling back out to Python code to trigger
3307 recursion depth updates/checks. Required the creation of a static

3351 remaining characters.
3352
Georg Brandl5cb76c12007-03-21 09:00:39 +00003353- Patch #1682205: a TypeError while unpacking an iterable is no longer

3357
Guido van Rossum143b5642007-03-23 04:58:42 +00003358- Bug #1683368: The object.__init__() and object.__new__() methods are
3359 now stricter in rejecting excess arguments. The only time when
3360 either allows excess arguments is when it is not overridden and the
3361 other one is. For backwards compatibility, when both are
3362 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003363 warning later). Also, type.__init__() insists on the same signature
3364 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003366- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3367 object to complex using its __complex__() method before falling back
3368 to the __float__() method. Therefore, the functions in the cmath
3369 module now can operate on objects that define a __complex__()
3370 method.

3387
Georg Brandl7b9c5552007-03-12 14:30:05 +00003388- Bug #1678647: write a newline after printing an exception in any
3389 case, even when converting the value to a string failed.
3390
Georg Brandl871f1bc2007-03-12 13:17:36 +00003391- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392 its argument, if it exists. If not, it will work like before. This
3393 allows customizing the output of dir() in the presence of a
3394 __getattr__().

3403 parthensized forms. This means complex(repr(x)) now works instead of
3404 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003405
Georg Brandlaa2321b2007-03-07 00:40:28 +00003406- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003407 makes the filenames the warning module prints much more sensible
3408 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003421- Patch #1674228: when assigning a slice (old-style), check for the
3422 sq_ass_slice instead of the sq_slice slot.
3423
Georg Brandl3ee81df2008-05-17 18:14:43 +00003424- When printing an unraisable error, don't print exceptions. before

3506 method. This allows calling unicode() on exceptions classes
3507 directly to succeed.
Brett Cannon9adeab72006-09-20 18:34:28 +00003508
Georg Brandl4e933132006-09-06 20:05:58 +00003509- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003527 generator expressions (x for x, in ... ) works again. Fixing this
3528 problem required changing the .pyc magic number. This means that
3529 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003568- Removed uses of dict.has_key() from distutils, and uses of
3569 callable() from copy_reg.py, so the interpreter now starts up

Georg Brandl3ee81df2008-05-17 18:14:43 +00003977- Patch #1530482: add pydoc.render_doc() which returns the

3992
Georg Brandl92a6bae2007-03-13 17:43:32 +00003993- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003994 are set for invalid interpolation sequences that would lead to

4051 TestCase and TestSuite subclasses (not instances) are no longer
4052 accepted in TestSuite.addTest(). This should cause no
4053 incompatibility since it never made sense with ordinary subclasses
4054 -- the failure just occurred later, with a more cumbersome
4055 exception.

4337 with RFC 3207 and forgets any knowledge obtained from the server not
4338 obtained from the TLS negotiation itself. Patch contributed by Bill
4339 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004340
Georg Brandl3ee81df2008-05-17 18:14:43 +00004341- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004342 that the SMTP.starttls() caller no longer needs to call ehlo()
4343 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004344 does not claim to support starttls. Adds the
4345 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4426 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4427 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004429

Georg Brandl3ee81df2008-05-17 18:14:43 +00004444 time so that opening a database previously created with the DB_DUP
4445 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4446 opens. Specifically: dictionary assignment to a DB object will
4447 replace all values for a given key when the database allows

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004728- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004729 periodic threadstate and signal checking in tight loops. By
4730 default, this option is turned-off. It should only be enabled in
4731 debugged, performance critical applications.

4783
Georg Brandl3ee81df2008-05-17 18:14:43 +00004784- Unified naming convention for free lists and their limits. All free
4785 lists in Object/ are named ``free_list``, the counter ``numfree``
4786 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4787 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004788
Georg Brandl3ee81df2008-05-17 18:14:43 +00004789- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4790 to ``PyTuple_SetItem``, it can be used to populate a brand new
4791 frozenset; but it does not steal a reference to the added item.

4803
Georg Brandl3ee81df2008-05-17 18:14:43 +00004804- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4805 of w# format code incorrectly truncated the length to an int, even
4806 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4807 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004808

4829
4830- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4831 outside of pystate.c and should not be necessary.
4832
Georg Brandl3ee81df2008-05-17 18:14:43 +00004833- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4834 absolute imports. In earlier versions they might have used relative
4835 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004836
Georg Brandl3ee81df2008-05-17 18:14:43 +00004837- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4838 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004839
Georg Brandl3ee81df2008-05-17 18:14:43 +00004840- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004865- Removed the macfs module. It had been deprecated since Python 2.5.
4866 This lead to the deprecation of macostools.touched() as it relied
