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

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
Georg Brandl86edb142010-08-01 21:58:18 +000038- Issue #9354: Provide getsockopt() in asyncore's file_wrapper.
39
Benjamin Peterson85633362010-06-08 14:58:25 +000040- In the unicode/str.format(), raise a ValueError when indexes to arguments are
41 too large.
Benjamin Petersonc9719132010-06-07 22:27:32 +000042
Victor Stinnerc3e40e02010-05-25 22:40:38 +000043- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
44 and error handler, instead of writing to the C stderr file in utf-8
45
Brett Cannon7d006262010-05-20 18:41:08 +000046- Issue #7902: When using explicit relative import syntax, don't try
47 implicit relative import semantics.
48
Antoine Pitrou5de15942010-05-17 20:00:52 +000049- Issue #7079: Fix a possible crash when closing a file object while using
50 it from another thread. Patch by Daniel Stutzbach.
51
Mark Dickinsone02c9d22010-05-07 13:23:18 +000052- Issue #1533: fix inconsistency in range function argument
53 processing: any non-float non-integer argument is now converted to
54 an integer (if possible) using its __int__ method. Previously, only
55 small arguments were treated this way; larger arguments (those whose
56 __int__ was outside the range of a C long) would produce a TypeError.
57
Benjamin Petersonc218ce82010-04-16 22:43:53 +000058- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
59 passed to bytearray.
60
Benjamin Peterson8a488082010-04-06 21:55:35 +000061- Issue #8329: Don't return the same lists from select.select when no fds are

Victor Stinner4fd2ff92010-03-22 12:56:39 +000069
Victor Stinnerd156fa32010-03-21 13:32:31 +000070- Issue #7544: Preallocate thread memory before creating the thread to avoid
71 a fatal error in low memory condition.
72
Victor Stinner0217c952010-03-21 13:09:24 +000073- Issue #7820: The parser tokenizer restores all bytes in the right if
74 the BOM check fails.
75
Ronald Oussoren07466192010-04-18 14:34:22 +000076- Issue #7072: isspace(0xa0) is true on Mac OS X

79-----
80
81- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
82 embedders of the interpreter to set sys.argv without also modifying
83 sys.path. This helps fix `CVE-2008-5983
84 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

90 reads on a BZ2File object, rather than returning incorrect results.
91
R. David Murray0d023db2010-08-01 04:11:05 +000092- Issue #8620: when a Cmd is fed input that reaches EOF without a final

101
Gregory P. Smith034ec782010-07-25 20:00:02 +0000102- Issue #3704: cookielib was not properly handling URLs with a / in the

1603What's New in Python 2.6.1
1604==========================
1605
1606*Release date: 04-Dec-2008*
1607
1608Core and Builtins
1609-----------------
1610
1611- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1612 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1613 instead of throwing a MemoryError.
1614
1615- Issue #4367: Python would segfault during compiling when the unicodedata
1616 module couldn't be imported and \N escapes were present.
1617
1618- Issue #4348: Some bytearray methods returned that didn't cause any change to
1619 the bytearray, returned the same bytearray instead of a copy.
1620
1621- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1622
1623- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1624
1625- Issue #4048: The parser module now correctly validates relative imports.
1626
1627- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1628 exec statement.
1629
1630- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1631 method does not return iterators for the 4th and 5th items.
1632
1633- Issue #4209: Enabling unicode_literals and the print_function in the same
1634 __future__ import didn't work.
1635
1636- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1637 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1638 really executed because I cannot move to such directory on win2k)
1639
1640- Issue #4069: When set.remove(element) is used with a set element, the element
1641 is temporarily replaced with an equivalent frozenset. But the eventual
1642 KeyError would always report the empty frozenset([]) as the missing key. Now
1643 it correctly refers to the initial element.
1644
1645- Fixed C99 style comments in several files. Python is now C89 compatible
1646 again.

1794
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001795- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1796 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1797 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1798 ``printf`` function, whereas PyString_FromFormat has an independent
1799 implementation and uses "%zd" on all platforms for size_t values.
1800 This makes a difference on win64, where ``printf`` needs "%Id" to display
1801 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001821 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1822 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1824 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1825 type object.

1896 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1897 for catch_warnings() also led to an improvement in the raising of a
1898 DeprecationWarning related to warnings.warn_explicit().
1899

1919
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001920- Issue #2975: When compiling several extension modules with Visual Studio 2008
1921 from the same python interpreter, some environment variables would grow
1922 without limit.
1923
Benjamin Peterson37346b22008-08-23 20:27:43 +00001924- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001961What's New in Python 2.6 beta 3?
1962================================
1963
Barry Warsaw07a4a382008-08-21 01:15:08 +00001964*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001965
1966Core and Builtins
1967-----------------
1968
Guido van Rossumf8402962008-08-20 15:01:50 +00001969- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1970 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1971 extensions do not automatically benefit from the class attribute
1972 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1973 to their tp_flags field if they care. This is a backwards
1974 compatibility feature; in 3.0, all types will use the cache by
1975 default.
1976
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001977- Keyword arguments can now follow starred arguments. (``f(a, *args,
1978 keyword=23)`` is now valid syntax.)
1979
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001980- ctypes function pointers that are COM methods have a boolean True
1981 value again.
1982
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001983- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1984 by denying s# to parse objects that have a releasebuffer procedure,
1985 and introducing s*.
1986
Georg Brandl1e13ea92008-08-11 09:07:59 +00001987- Issue #3537: Fix an assertion failure when an empty but presized dict
1988 object was stored in the freelist.
1989
Mark Dickinsonb6467572008-08-04 21:30:09 +00001990- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1991 ValueError consistently across platforms.
1992
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001993- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1994 (64bit Unix, for example), unichr() would truncate its argument and return
1995 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1996
Neal Norwitze7d8be82008-07-31 17:17:14 +00001997- Apply security patches from Apple.
1998
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001999- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2000 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2001
Antoine Pitrou92f82162008-07-25 22:22:08 +00002002- Issue #1819: function calls with several named parameters are now on
2003 average 35% faster (as measured by pybench).
2004
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002005- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2006 the python debugger steps into a class statement: the free variables (local
2007 variables defined in an outer scope) would be deleted from the outer scope.
2008
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002009- Issue #2620: Overflow checking when allocating or reallocating memory
2010 was not always being done properly in some python types and extension
2011 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2012 all been updated to perform better checks and places in the code that
2013 would previously leak memory on the error path when such an allocation
2014 failed have been fixed.
2015
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002016Library
2017-------
2018

2022 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2023
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002024- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2025 version reported by these tools does not necessarily follow the python
2026 version numbering scheme, so the module is less strict when parsing it.
2027
Nick Coghlanf70385a2008-08-18 12:42:46 +00002028- Issue #2235: Added Py3k warnings for types which will become unhashable
2029 under the stricter __hash__ inheritance rules in 3.0. Several types
2030 which did not meet the rules for hash invariants and were already
2031 unhashable in 3.0 have now been explicitly flagged as unhashable in
2032 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2033 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2034
Brett Cannon88f801d2008-08-18 00:46:22 +00002035- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2043
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002044- Issue #3575: Incremental decoder's decode function now takes bytearray
2045 by using 's*' instead of 't#'.
2046
Jesus Cea585ad8a2009-07-02 15:37:21 +00002047- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002048 fails unicode conversion on 2nd parameter. (windows only)
2049
Facundo Batista94f243a2008-08-17 03:38:39 +00002050- Issue 2464. urllib2 now supports a malformation in the URL received
2051 in a redirect.
2052
Brett Cannonabe423e2008-08-16 21:47:07 +00002053- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002054 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002055
Facundo Batistaeb90b782008-08-16 14:44:07 +00002056- Issue #2776: fixed small issue when handling an URL with double slash
2057 after a 302 response in the case of not going through a proxy.
2058
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002059- Issue #2676: in the email package, content-type parsing was hanging on
2060 pathological input because of quadratic or exponential behaviour of a
2061 regular expression.
2062
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002063- Issue #3476: binary buffered reading through the new "io" library is now
2064 thread-safe.
2065
Brett Cannonbf3157b2008-08-14 05:00:03 +00002066- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2067 since mimetools itself is deprecated. Because modules are cached, all
2068 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2069
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002070- Issue #3134: shutil referenced undefined WindowsError symbol.
2071
Robert Schuppenies14646332008-08-10 11:01:53 +00002072- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2073 menu entries were not deleted.
2074
Brett Cannon83e81842008-08-09 23:30:55 +00002075- Copied the implementation of reduce() to _functools.reduce() to have a
2076 version that did not raise a DeprecationWarning under -3.
2077
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002078- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2079 a MemoryError rather than silently stop the iteration.
2080
Guido van Rossum59ce9012008-08-09 14:55:34 +00002081- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2082 to _sre.compile() will now be rejected. This should not affect anybody
2083 since the re.compile() function never generates invalid re-bytecode.
2084
Skip Montanaroa032bf42008-08-08 22:52:51 +00002085- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002104 asking for a specific length. This problem only affected files opened
2105 using the new "io" module, not the built-in open() function.

Georg Brandl3e483f62008-07-16 22:57:41 +00002163- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2164 its methods now allow for items objects that can be converted to
2165 an integer using operator.index().
2166
Mark Dickinson64b7e502008-07-16 09:40:03 +00002167- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2168 produced a ValueError instead of giving the correct float.
2169
Eric Smitha5fa5a22008-07-16 00:11:49 +00002170- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2171 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2172
Mark Dickinson7103aa42008-07-15 19:08:33 +00002173- Issue #3008: the float type has a new instance method 'float.hex'
2174 and a new class method 'float.fromhex' to convert floating-point
2175 numbers to and from hexadecimal strings, respectively.
2176
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002177- Issue #2235: __hash__ is once again inherited by default. To allow
2178 collections.Hashable to remain meaningful in the presence of the
2179 default hash implementation (object.__hash__), it is now possible
2180 to explicit block inheritance of hash by setting __hash__=None at
2181 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2182 level.
2183
Nick Coghlanb028f502008-07-13 14:52:36 +00002184- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2185 the parent module cannot be found while performing an absolute import.
2186 This means that an incorrectly defined __package__ attribute will
2187 now only prevent relative imports in that module rather than causing
2188 all imports from that module to fail.
2189
Nick Coghlan14ff9942008-07-08 14:21:42 +00002190- Issue #2517: Allow unicode messages in Exceptions again by correctly
2191 bypassing the instance dictionary when looking up __unicode__ on
2192 new-style classes.
2193
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002194- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2195 set to a custom object whose write() method happens to install
2196 another file in sys.stdout.
2197
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002198- Issue #3088: Corrected a race condition in classes derived from
2199 threading.local: the first member set by a thread could be saved in
2200 another thread's dictionary.
2201
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002202- Issue #3004: Minor change to slice.indices(): the start and stop
2203 arguments are now treated identically, making the behaviour easier
2204 to describe and understand. For example, slice(None, -10,
2205 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2206 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2207 10, -1).
2208
Georg Brandl278fc502008-07-19 12:46:12 +00002209- Issue #3219: Calling a function with repeated keyword arguments,
2210 f(a=2, a=23), would not cause a syntax error. This was a regression
2211 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002212
Georg Brandl278fc502008-07-19 12:46:12 +00002213- Issue #2862: Make int and float freelist management consistent with
2214 other freelists. Changes their CompactFreeList apis into
2215 ClearFreeList apis and calls them via gc.collect().

2219
Thomas Heller57adf222008-08-14 19:10:48 +00002220- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2221 api functions without holding the GIL, which could lead to a fatal
2222 error when they failed.
2223
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002224- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2233 ForkingPickler.register() to resolve conflict with ctypes.
2234
Vinay Sajip51e65192008-07-18 09:01:10 +00002235- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002236

2246
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002247- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002248
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002249- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2250 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002251 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002252 content-length. The problem had been corrected in the 2.4 branch, but never
2253 merged into trunk.
2254
Georg Brandle78fbcc2008-07-05 10:13:36 +00002255- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002268- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2269 handling is now the same as that of other special attributes like __name__).
2270
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002271- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002723- Issue #1631171: Re-implement the 'warnings' module in C (the
2724 original Python code has been kept as backup). This will allow for
2725 using the 'warning's machinery in such places as the parser where
2726 use of pure Python code is not possible. Both the ``showarning()``
2727 and ``formatwarning()`` gain an optional 'line' argument which is
2728 not called by default for backwards-compatibility reasons. Setting
2729 ``warnings.showwarning()`` to an implementation that lacks support
2730 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002793- Issue #2550: The approach used by client/server code for obtaining
2794 ports to listen on in network-oriented tests has been refined in an
2795 effort to facilitate running multiple instances of the entire
2796 regression test suite in parallel without issue.
2797 test_support.bind_port() has been fixed such that it will always
2798 return a unique port -- which wasn't always the case with the
2799 previous implementation, especially if socket options had been set
2800 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2801 new implementation of bind_port() will actually raise an exception
2802 if it is passed an AF_INET/SOCK_STREAM socket with either the
2803 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2804 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2805 the socket it's been passed. This currently only applies to
2806 Windows. This option prevents any other sockets from binding to the
2807 host/port we've bound to, thus removing the possibility of the
2808 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2809 when a second SOCK_STREAM socket binds and accepts to a host/port
2810 that's already been bound by another socket. The optional preferred
2811 port parameter to bind_port() has been removed. Under no
2812 circumstances should tests be hard coding ports!
2813
2814 test_support.find_unused_port() has also been introduced, which will
2815 pass a temporary socket object to bind_port() in order to obtain an
2816 unused port. The temporary socket object is then closed and
2817 deleted, and the port is returned. This method should only be used
2818 for obtaining an unused port in order to pass to an external program
2819 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2820 a parameter to a server-oriented class that doesn't give you direct
2821 access to the underlying socket used.
2822
2823 Finally, test_support.HOST has been introduced, which should be used
2824 for the host argument of any relevant socket calls (i.e. bind and
2825 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002826
2827 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002828 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002829 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2830 test_asynchat and test_socket_ssl.
2831
Georg Brandl3ee81df2008-05-17 18:14:43 +00002832 It is now possible for multiple instances of the regression test
2833 suite to run in parallel without issue.

2989 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002990 platform.machine() and platform.processor() will report this
2991 information as well.

3036
Thomas Heller78b8f442008-03-05 14:53:39 +00003037- The bundled libffi copy is now in sync with the recently released
3038 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi

3100-----------------
3101
Fred Drakea8ee94b2008-03-01 02:45:07 +00003102- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003103 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003104
Georg Brandlad61bc82008-02-23 15:11:18 +00003105- Issue #2067: file.__exit__() now calls subclasses' close() method.
3106
3107- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003108
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003109- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003110 issue 215555 for a discussion.
3111
Eric Smitha73fbe72008-02-23 03:09:44 +00003112- Added the future_builtins module, which contains hex() and oct().
3113 These are the PEP 3127 version of these functions, designed to be
3114 compatible with the hex() and oct() builtins from Python 3.0. They
3115 differ slightly in their output formats from the existing, unchanged
3116 Python 2.6 builtins. The expected usage of the future_builtins
3117 module is:
3118 from future_builtins import hex, oct
3119
Eric Smith7ef40bf2008-02-20 23:34:22 +00003120- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3121 exponents for exponents with absolute value < 100. Follows C99
3122 standard. This is a change on Windows, which would use 3 digits.
3123 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3124 so that any alterations it does to the resulting string will be
3125 available in stringlib/formatter.h (for float.__format__).
3126
Eric Smith5a3c1352008-02-19 13:21:56 +00003127- Implemented PEP 3101, Advanced String Formatting. This adds a new
3128 builtin format(); a format() method for str and unicode; a
3129 __format__() method to object, str, unicode, int, long, float, and
3130 datetime; the class string.Formatter; and the C API
3131 PyObject_Format().
3132
Georg Brandl3ee81df2008-05-17 18:14:43 +00003133- Fixed several potential crashes, all caused by specially crafted
3134 __del__ methods exploiting objects in temporarily inconsistent
3135 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003136
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003137- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003138 prevent a possible crash: an Abstract Base Class would try to access
3139 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003140
Georg Brandl3ee81df2008-05-17 18:14:43 +00003141- Fixed repr() and str() of complex numbers with infinity or nan as
3142 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003143
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144- Clear all free lists during a gc.collect() of the highest generation
3145 in order to allow pymalloc to free more arenas. Python may give back
3146 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003147
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- Issue #2045: Fix an infinite recursion triggered when printing a
3149 subclass of collections.defaultdict, if its default_factory is set
3150 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003151
Christian Heimesf75dbef2008-02-08 00:11:31 +00003152- Fixed a minor memory leak in dictobject.c. The content of the free
3153 list was not freed on interpreter shutdown.
3154
Georg Brandl5a7eca12010-03-21 19:29:04 +00003155- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003156 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003157
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3159 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003160 to compact the internal free lists of pre-allocted ints and floats.
3161
Georg Brandl3ee81df2008-05-17 18:14:43 +00003162- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3163 calls. Python expected the return type int but the fork familie
3164 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003165
Georg Brandl3ee81df2008-05-17 18:14:43 +00003166- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3167 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003168
Georg Brandl3ee81df2008-05-17 18:14:43 +00003169- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3170 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003171
Georg Brandl3ee81df2008-05-17 18:14:43 +00003172- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3173 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00003175- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3176 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003177
Georg Brandl3ee81df2008-05-17 18:14:43 +00003178- Patch #1473257: generator objects gain a gi_code attribute. This is
3179 the same object as the func_code attribute of the function that
3180 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182- Issue #1920: "while 0" statements were completely removed by the
3183 compiler, even in the presence of an "else" clause, which is
3184 supposed to be run when the condition is false. Now the compiler
3185 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003186
Guido van Rossumeead05f2008-01-24 18:21:02 +00003187- A few crashers fixed: weakref_in_del.py (issue #1377858);
3188 loosing_dict_ref.py (issue #1303614, test67.py);
3189 borrowed_ref_[34].py (not in tracker).
3190
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003191- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003192 suppressed while an extension is loaded by calling SetErrorMode in
3193 dynload_win.c. The error is still reported properly.
3194
Georg Brandl3ee81df2008-05-17 18:14:43 +00003195- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003196 several extension methods and modules do not work without unicode
3197 support.
3198
Georg Brandl26543b12008-01-21 18:36:51 +00003199- Issue #1882: when compiling code from a string, encoding cookies in the
3200 second line of code were not always recognized correctly.
3201
Georg Brandl14404b62008-01-19 19:27:05 +00003202- Issue #1679: "0x" was taken as a valid integer literal.
3203
Georg Brandl6caad7d2008-01-26 14:19:22 +00003204- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003205 added.
3206
Christian Heimesc94e2b52008-01-14 04:13:37 +00003207- sys.float_info / PyFloat_GetInfo: The floating point information
3208 object was converted from a dict to a specialized structseq object.
3209
Georg Brandl3ee81df2008-05-17 18:14:43 +00003210- Patch #1816: Added sys.flags structseq. It exposes the status of
3211 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003212
Georg Brandl3ee81df2008-05-17 18:14:43 +00003213- Objects/structseq.c: Implemented new structseq representation. The
3214 patch makes structseqs (e.g. the return value of os.stat) more
3215 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003216
Georg Brandl3ee81df2008-05-17 18:14:43 +00003217- Patch #1700288: added a type attribute cache that caches method
3218 accesses, resulting in speedups in heavily object-oriented code.

3226 envvar and sys.dont_write_bytecode attribute. All these can be set
3227 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003228
Georg Brandl3ee81df2008-05-17 18:14:43 +00003229- Improve some exception messages when Windows fails to load an
3230 extension module. Now we get for example '%1 is not a valid Win32
3231 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003238- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003239 and INF. float("nan"), float("inf") and float("-inf") now work on
3240 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003242- Compiler now generates simpler and faster code for dictionary
3243 literals. The oparg for BUILD_MAP now indicates an estimated
3244 dictionary size. There is a new opcode, STORE_MAP, for adding
3245 entries to the dictionary.

3275 file can now be directly executed by passing their name to the
3276 interpreter. The directory/zipfile is automatically inserted as the
3277 first entry in sys.path.

3280 function uses a generator expression when at the same time the
3281 executed code is closing a paused generator.

3288
Georg Brandl5a7eca12010-03-21 19:29:04 +00003289- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003290 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3291 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003292
Georg Brandl3ee81df2008-05-17 18:14:43 +00003293- Issue #1686386: Tuple's tp_repr did not take into account the
3294 possibility of having a self-referential tuple, which is possible
3295 from C code. Nor did object's tp_str consider that a type's tp_str
3296 could do something that could lead to an inifinite recursion.
3297 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3298 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003299
Georg Brandl3ee81df2008-05-17 18:14:43 +00003300- Issue #1164: It was possible to trigger deadlock when using the
3301 'print' statement to write to a file since the GIL was not released
3302 as needed. Now PyObject_Print() does the right thing along with
3303 various tp_print implementations of the built-in types and those in
3304 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003305
Georg Brandl3ee81df2008-05-17 18:14:43 +00003306- Issue #1147: Exceptions were directly allowing string exceptions in

3308 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00003312
Brett Cannon1e534b52007-09-07 04:18:30 +00003313- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003314 PyObject_Call() never calling back out to Python code to trigger
3315 recursion depth updates/checks. Required the creation of a static
3316 RuntimeError instance in case normalizing an exception put the
3317 recursion check value past its limit. Fixes crashers
3318 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003319

Neal Norwitz0ac60192007-05-27 04:08:54 +00003333- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003334 __*__ attributes. (Some already existed, e.g., __doc__ and
3335 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003336
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003337- Add -3 option to the interpreter to warn about features that are
3338 deprecated and will be changed/removed in Python 3.0.
3339
Georg Brandl2134e752007-05-21 20:34:16 +00003340- Patch #1686487: you can now pass any mapping after '**' in function
3341 calls.
3342
Collin Winter62903052007-05-18 23:11:24 +00003343- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003344 "except E as target:". This is to provide forwards compatibility
3345 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003346
Brett Cannon229cee22007-05-05 01:34:02 +00003347- Deprecate BaseException.message as per PEP 352.
3348
Georg Brandl3ee81df2008-05-17 18:14:43 +00003349- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003350 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003351
Vinay Sajip8549ce32007-05-06 17:53:37 +00003352- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003353 setting a plain string, ie don't expand to single letter identifiers.
3354
Raymond Hettinger13936692007-04-11 18:40:58 +00003355- Request #1191699: Slices can now be pickled.
3356
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003357- Request #1193128: str.translate() now allows a None argument for
3358 translations that only remove characters without re-mapping the
3359 remaining characters.
3360
Georg Brandl5cb76c12007-03-21 09:00:39 +00003361- Patch #1682205: a TypeError while unpacking an iterable is no longer
3362 masked by a generic one with the message "unpack non-sequence".
3363
Neal Norwitzaa754b72007-03-21 06:39:48 +00003364- Remove unused file Python/fmod.c.
3365
Guido van Rossum143b5642007-03-23 04:58:42 +00003366- Bug #1683368: The object.__init__() and object.__new__() methods are
3367 now stricter in rejecting excess arguments. The only time when
3368 either allows excess arguments is when it is not overridden and the
3369 other one is. For backwards compatibility, when both are
3370 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003371 warning later). Also, type.__init__() insists on the same signature
3372 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003373
Georg Brandl3ee81df2008-05-17 18:14:43 +00003374- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3375 object to complex using its __complex__() method before falling back
3376 to the __float__() method. Therefore, the functions in the cmath
3377 module now can operate on objects that define a __complex__()
3378 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003379
Georg Brandl3ee81df2008-05-17 18:14:43 +00003380- Patch #1623563: allow __class__ assignment for classes with
3381 __slots__. The old and the new class are still required to have the
3382 same slot names.

3388 ``object.__reduce_ex__()`` is called with an object that is faking
3389 its type.

3395
Georg Brandl7b9c5552007-03-12 14:30:05 +00003396- Bug #1678647: write a newline after printing an exception in any
3397 case, even when converting the value to a string failed.
3398
Georg Brandl871f1bc2007-03-12 13:17:36 +00003399- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003400 its argument, if it exists. If not, it will work like before. This
3401 allows customizing the output of dir() in the presence of a
3402 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003403
Collin Winter276887b2007-03-12 16:11:39 +00003404- Patch #922167: Python no longer segfaults when faced with infinitely
3405 self-recursive reload() calls (as reported by bug #742342).
3406
Georg Brandl3ee81df2008-05-17 18:14:43 +00003407- Patch #1675981: remove unreachable code from ``type.__new__()``

3411 parthensized forms. This means complex(repr(x)) now works instead of
3412 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003413
Georg Brandlaa2321b2007-03-07 00:40:28 +00003414- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003415 makes the filenames the warning module prints much more sensible
3416 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003417

3419 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003420 variable is given, but break into the interactive interpreter just
3421 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003429- Patch #1674228: when assigning a slice (old-style), check for the
3430 sq_ass_slice instead of the sq_slice slot.
3431
Georg Brandl3ee81df2008-05-17 18:14:43 +00003432- When printing an unraisable error, don't print exceptions. before
3433 the name. This duplicates the behavior whening normally printing
3434 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004002 are set for invalid interpolation sequences that would lead to

4059 TestCase and TestSuite subclasses (not instances) are no longer
4060 accepted in TestSuite.addTest(). This should cause no
4061 incompatibility since it never made sense with ordinary subclasses
4062 -- the failure just occurred later, with a more cumbersome
4063 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004350 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004352 does not claim to support starttls. Adds the
4353 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004451- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004452 time so that opening a database previously created with the DB_DUP
4453 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4454 opens. Specifically: dictionary assignment to a DB object will
4455 replace all values for a given key when the database allows
4456 duplicate values. DB users should use DB.put(k, v) when they want
4457 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004737 periodic threadstate and signal checking in tight loops. By
4738 default, this option is turned-off. It should only be enabled in

Georg Brandl3ee81df2008-05-17 18:14:43 +00004797- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4798 to ``PyTuple_SetItem``, it can be used to populate a brand new

4811
Georg Brandl3ee81df2008-05-17 18:14:43 +00004812- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4813 of w# format code incorrectly truncated the length to an int, even
4814 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4815 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004845- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4846 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004847
