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>`_.

95 mode doesn't add a BOM at the end of the file if the file isn't empty.
96
Gregory P. Smith034ec782010-07-25 20:00:02 +000097- Issue #3704: cookielib was not properly handling URLs with a / in the

1598What's New in Python 2.6.1
1599==========================
1600
1601*Release date: 04-Dec-2008*
1602
1603Core and Builtins
1604-----------------
1605
1606- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1607 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1608 instead of throwing a MemoryError.
1609
1610- Issue #4367: Python would segfault during compiling when the unicodedata
1611 module couldn't be imported and \N escapes were present.
1612
1613- Issue #4348: Some bytearray methods returned that didn't cause any change to
1614 the bytearray, returned the same bytearray instead of a copy.
1615
1616- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1617
1618- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1619
1620- Issue #4048: The parser module now correctly validates relative imports.
1621
1622- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1623 exec statement.
1624
1625- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1626 method does not return iterators for the 4th and 5th items.
1627
1628- Issue #4209: Enabling unicode_literals and the print_function in the same
1629 __future__ import didn't work.
1630
1631- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1632 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1633 really executed because I cannot move to such directory on win2k)
1634
1635- Issue #4069: When set.remove(element) is used with a set element, the element
1636 is temporarily replaced with an equivalent frozenset. But the eventual
1637 KeyError would always report the empty frozenset([]) as the missing key. Now
1638 it correctly refers to the initial element.
1639
1640- Fixed C99 style comments in several files. Python is now C89 compatible
1641 again.

1789
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001790- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1791 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1792 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1793 ``printf`` function, whereas PyString_FromFormat has an independent
1794 implementation and uses "%zd" on all platforms for size_t values.
1795 This makes a difference on win64, where ``printf`` needs "%Id" to display
1796 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001798- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Antoine Pitrou0668c622008-08-26 22:42:08 +00001816 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1817 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1818 when given a tuple of classes as second argument, were looking up
1819 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1820 type object.

1891 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1892 for catch_warnings() also led to an improvement in the raising of a
1893 DeprecationWarning related to warnings.warn_explicit().
1894

1914
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001915- Issue #2975: When compiling several extension modules with Visual Studio 2008
1916 from the same python interpreter, some environment variables would grow
1917 without limit.
1918
Benjamin Peterson37346b22008-08-23 20:27:43 +00001919- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001956What's New in Python 2.6 beta 3?
1957================================
1958
Barry Warsaw07a4a382008-08-21 01:15:08 +00001959*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001960
1961Core and Builtins
1962-----------------
1963
Guido van Rossumf8402962008-08-20 15:01:50 +00001964- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1965 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1966 extensions do not automatically benefit from the class attribute
1967 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1968 to their tp_flags field if they care. This is a backwards
1969 compatibility feature; in 3.0, all types will use the cache by
1970 default.
1971
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001972- Keyword arguments can now follow starred arguments. (``f(a, *args,
1973 keyword=23)`` is now valid syntax.)
1974
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001975- ctypes function pointers that are COM methods have a boolean True
1976 value again.
1977
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001978- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1979 by denying s# to parse objects that have a releasebuffer procedure,
1980 and introducing s*.
1981
Georg Brandl1e13ea92008-08-11 09:07:59 +00001982- Issue #3537: Fix an assertion failure when an empty but presized dict
1983 object was stored in the freelist.
1984
Mark Dickinsonb6467572008-08-04 21:30:09 +00001985- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1986 ValueError consistently across platforms.
1987
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001988- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1989 (64bit Unix, for example), unichr() would truncate its argument and return
1990 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1991
Neal Norwitze7d8be82008-07-31 17:17:14 +00001992- Apply security patches from Apple.
1993
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001994- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1995 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1996
Antoine Pitrou92f82162008-07-25 22:22:08 +00001997- Issue #1819: function calls with several named parameters are now on
1998 average 35% faster (as measured by pybench).
1999
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002000- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2001 the python debugger steps into a class statement: the free variables (local
2002 variables defined in an outer scope) would be deleted from the outer scope.
2003
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002004- Issue #2620: Overflow checking when allocating or reallocating memory
2005 was not always being done properly in some python types and extension
2006 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2007 all been updated to perform better checks and places in the code that
2008 would previously leak memory on the error path when such an allocation
2009 failed have been fixed.
2010
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002011Library
2012-------
2013

2017 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2018
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002019- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2020 version reported by these tools does not necessarily follow the python
2021 version numbering scheme, so the module is less strict when parsing it.
2022
Nick Coghlanf70385a2008-08-18 12:42:46 +00002023- Issue #2235: Added Py3k warnings for types which will become unhashable
2024 under the stricter __hash__ inheritance rules in 3.0. Several types
2025 which did not meet the rules for hash invariants and were already
2026 unhashable in 3.0 have now been explicitly flagged as unhashable in
2027 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2028 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2029
Brett Cannon88f801d2008-08-18 00:46:22 +00002030- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2031 imported into the module but exposed as part of the module's API.

2034
Brett Cannon46225e72008-08-18 00:36:52 +00002035- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2038
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002039- Issue #3575: Incremental decoder's decode function now takes bytearray
2040 by using 's*' instead of 't#'.
2041
Jesus Cea585ad8a2009-07-02 15:37:21 +00002042- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002043 fails unicode conversion on 2nd parameter. (windows only)
2044
Facundo Batista94f243a2008-08-17 03:38:39 +00002045- Issue 2464. urllib2 now supports a malformation in the URL received
2046 in a redirect.
2047
Brett Cannonabe423e2008-08-16 21:47:07 +00002048- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002049 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002050
Facundo Batistaeb90b782008-08-16 14:44:07 +00002051- Issue #2776: fixed small issue when handling an URL with double slash
2052 after a 302 response in the case of not going through a proxy.
2053
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002054- Issue #2676: in the email package, content-type parsing was hanging on
2055 pathological input because of quadratic or exponential behaviour of a
2056 regular expression.
2057
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002058- Issue #3476: binary buffered reading through the new "io" library is now
2059 thread-safe.
2060
Brett Cannonbf3157b2008-08-14 05:00:03 +00002061- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2062 since mimetools itself is deprecated. Because modules are cached, all
2063 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2064
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002065- Issue #3134: shutil referenced undefined WindowsError symbol.
2066
Robert Schuppenies14646332008-08-10 11:01:53 +00002067- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2068 menu entries were not deleted.
2069
Brett Cannon83e81842008-08-09 23:30:55 +00002070- Copied the implementation of reduce() to _functools.reduce() to have a
2071 version that did not raise a DeprecationWarning under -3.
2072
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002073- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2074 a MemoryError rather than silently stop the iteration.
2075
Guido van Rossum59ce9012008-08-09 14:55:34 +00002076- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2077 to _sre.compile() will now be rejected. This should not affect anybody
2078 since the re.compile() function never generates invalid re-bytecode.
2079
Skip Montanaroa032bf42008-08-08 22:52:51 +00002080- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002099 asking for a specific length. This problem only affected files opened
2100 using the new "io" module, not the built-in open() function.

2127 mode 0600 rather than 000 under Unix.
2128
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002129- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Georg Brandl3e483f62008-07-16 22:57:41 +00002158- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2159 its methods now allow for items objects that can be converted to
2160 an integer using operator.index().
2161
Mark Dickinson64b7e502008-07-16 09:40:03 +00002162- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2163 produced a ValueError instead of giving the correct float.
2164
Eric Smitha5fa5a22008-07-16 00:11:49 +00002165- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2166 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2167
Mark Dickinson7103aa42008-07-15 19:08:33 +00002168- Issue #3008: the float type has a new instance method 'float.hex'
2169 and a new class method 'float.fromhex' to convert floating-point
2170 numbers to and from hexadecimal strings, respectively.
2171
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002172- Issue #2235: __hash__ is once again inherited by default. To allow
2173 collections.Hashable to remain meaningful in the presence of the
2174 default hash implementation (object.__hash__), it is now possible
2175 to explicit block inheritance of hash by setting __hash__=None at
2176 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2177 level.
2178
Nick Coghlanb028f502008-07-13 14:52:36 +00002179- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2180 the parent module cannot be found while performing an absolute import.
2181 This means that an incorrectly defined __package__ attribute will
2182 now only prevent relative imports in that module rather than causing
2183 all imports from that module to fail.
2184
Nick Coghlan14ff9942008-07-08 14:21:42 +00002185- Issue #2517: Allow unicode messages in Exceptions again by correctly
2186 bypassing the instance dictionary when looking up __unicode__ on
2187 new-style classes.
2188
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002189- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2190 set to a custom object whose write() method happens to install
2191 another file in sys.stdout.
2192
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002193- Issue #3088: Corrected a race condition in classes derived from
2194 threading.local: the first member set by a thread could be saved in
2195 another thread's dictionary.
2196
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002197- Issue #3004: Minor change to slice.indices(): the start and stop
2198 arguments are now treated identically, making the behaviour easier
2199 to describe and understand. For example, slice(None, -10,
2200 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2201 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2202 10, -1).
2203
Georg Brandl278fc502008-07-19 12:46:12 +00002204- Issue #3219: Calling a function with repeated keyword arguments,
2205 f(a=2, a=23), would not cause a syntax error. This was a regression
2206 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002207
Georg Brandl278fc502008-07-19 12:46:12 +00002208- Issue #2862: Make int and float freelist management consistent with
2209 other freelists. Changes their CompactFreeList apis into
2210 ClearFreeList apis and calls them via gc.collect().

2214
Thomas Heller57adf222008-08-14 19:10:48 +00002215- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2216 api functions without holding the GIL, which could lead to a fatal
2217 error when they failed.
2218
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002219- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2228 ForkingPickler.register() to resolve conflict with ctypes.
2229
Vinay Sajip51e65192008-07-18 09:01:10 +00002230- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002231

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002243
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002244- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2245 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002246 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002247 content-length. The problem had been corrected in the 2.4 branch, but never
2248 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002263- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2264 handling is now the same as that of other special attributes like __name__).
2265
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002266- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002718- Issue #1631171: Re-implement the 'warnings' module in C (the
2719 original Python code has been kept as backup). This will allow for
2720 using the 'warning's machinery in such places as the parser where
2721 use of pure Python code is not possible. Both the ``showarning()``
2722 and ``formatwarning()`` gain an optional 'line' argument which is
2723 not called by default for backwards-compatibility reasons. Setting
2724 ``warnings.showwarning()`` to an implementation that lacks support
2725 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002788- Issue #2550: The approach used by client/server code for obtaining
2789 ports to listen on in network-oriented tests has been refined in an
2790 effort to facilitate running multiple instances of the entire
2791 regression test suite in parallel without issue.
2792 test_support.bind_port() has been fixed such that it will always
2793 return a unique port -- which wasn't always the case with the
2794 previous implementation, especially if socket options had been set
2795 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2796 new implementation of bind_port() will actually raise an exception
2797 if it is passed an AF_INET/SOCK_STREAM socket with either the
2798 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2799 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2800 the socket it's been passed. This currently only applies to
2801 Windows. This option prevents any other sockets from binding to the
2802 host/port we've bound to, thus removing the possibility of the
2803 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2804 when a second SOCK_STREAM socket binds and accepts to a host/port
2805 that's already been bound by another socket. The optional preferred
2806 port parameter to bind_port() has been removed. Under no
2807 circumstances should tests be hard coding ports!
2808
2809 test_support.find_unused_port() has also been introduced, which will
2810 pass a temporary socket object to bind_port() in order to obtain an
2811 unused port. The temporary socket object is then closed and
2812 deleted, and the port is returned. This method should only be used
2813 for obtaining an unused port in order to pass to an external program
2814 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2815 a parameter to a server-oriented class that doesn't give you direct
2816 access to the underlying socket used.
2817
2818 Finally, test_support.HOST has been introduced, which should be used
2819 for the host argument of any relevant socket calls (i.e. bind and
2820 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002821
2822 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002823 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002824 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2825 test_asynchat and test_socket_ssl.
2826
Georg Brandl3ee81df2008-05-17 18:14:43 +00002827 It is now possible for multiple instances of the regression test
2828 suite to run in parallel without issue.

2984 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002985 platform.machine() and platform.processor() will report this
2986 information as well.

3095-----------------
3096
Fred Drakea8ee94b2008-03-01 02:45:07 +00003097- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003098 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003099
Georg Brandlad61bc82008-02-23 15:11:18 +00003100- Issue #2067: file.__exit__() now calls subclasses' close() method.
3101
3102- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003103
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003104- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003105 issue 215555 for a discussion.
3106
Eric Smitha73fbe72008-02-23 03:09:44 +00003107- Added the future_builtins module, which contains hex() and oct().
3108 These are the PEP 3127 version of these functions, designed to be
3109 compatible with the hex() and oct() builtins from Python 3.0. They
3110 differ slightly in their output formats from the existing, unchanged
3111 Python 2.6 builtins. The expected usage of the future_builtins
3112 module is:
3113 from future_builtins import hex, oct
3114
Eric Smith7ef40bf2008-02-20 23:34:22 +00003115- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3116 exponents for exponents with absolute value < 100. Follows C99
3117 standard. This is a change on Windows, which would use 3 digits.
3118 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3119 so that any alterations it does to the resulting string will be
3120 available in stringlib/formatter.h (for float.__format__).
3121
Eric Smith5a3c1352008-02-19 13:21:56 +00003122- Implemented PEP 3101, Advanced String Formatting. This adds a new
3123 builtin format(); a format() method for str and unicode; a
3124 __format__() method to object, str, unicode, int, long, float, and
3125 datetime; the class string.Formatter; and the C API
3126 PyObject_Format().
3127
Georg Brandl3ee81df2008-05-17 18:14:43 +00003128- Fixed several potential crashes, all caused by specially crafted
3129 __del__ methods exploiting objects in temporarily inconsistent
3130 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003131
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003132- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003133 prevent a possible crash: an Abstract Base Class would try to access
3134 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Fixed repr() and str() of complex numbers with infinity or nan as
3137 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003138
Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- Clear all free lists during a gc.collect() of the highest generation
3140 in order to allow pymalloc to free more arenas. Python may give back
3141 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003142
Georg Brandl3ee81df2008-05-17 18:14:43 +00003143- Issue #2045: Fix an infinite recursion triggered when printing a
3144 subclass of collections.defaultdict, if its default_factory is set
3145 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003146
Christian Heimesf75dbef2008-02-08 00:11:31 +00003147- Fixed a minor memory leak in dictobject.c. The content of the free
3148 list was not freed on interpreter shutdown.
3149
Georg Brandl5a7eca12010-03-21 19:29:04 +00003150- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003151 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003152
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3154 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003155 to compact the internal free lists of pre-allocted ints and floats.
3156
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3158 calls. Python expected the return type int but the fork familie
3159 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3162 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003163
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3165 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003166

Georg Brandl3ee81df2008-05-17 18:14:43 +00003170- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3171 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003172
Georg Brandl3ee81df2008-05-17 18:14:43 +00003173- Patch #1473257: generator objects gain a gi_code attribute. This is
3174 the same object as the func_code attribute of the function that
3175 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003176
Georg Brandl3ee81df2008-05-17 18:14:43 +00003177- Issue #1920: "while 0" statements were completely removed by the
3178 compiler, even in the presence of an "else" clause, which is
3179 supposed to be run when the condition is false. Now the compiler
3180 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003181
Guido van Rossumeead05f2008-01-24 18:21:02 +00003182- A few crashers fixed: weakref_in_del.py (issue #1377858);
3183 loosing_dict_ref.py (issue #1303614, test67.py);
3184 borrowed_ref_[34].py (not in tracker).
3185
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003186- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003187 suppressed while an extension is loaded by calling SetErrorMode in
3188 dynload_win.c. The error is still reported properly.
3189
Georg Brandl3ee81df2008-05-17 18:14:43 +00003190- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003191 several extension methods and modules do not work without unicode
3192 support.
3193
Georg Brandl26543b12008-01-21 18:36:51 +00003194- Issue #1882: when compiling code from a string, encoding cookies in the
3195 second line of code were not always recognized correctly.
3196
Georg Brandl14404b62008-01-19 19:27:05 +00003197- Issue #1679: "0x" was taken as a valid integer literal.
3198
Georg Brandl6caad7d2008-01-26 14:19:22 +00003199- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003200 added.
3201
Christian Heimesc94e2b52008-01-14 04:13:37 +00003202- sys.float_info / PyFloat_GetInfo: The floating point information
3203 object was converted from a dict to a specialized structseq object.
3204
Georg Brandl3ee81df2008-05-17 18:14:43 +00003205- Patch #1816: Added sys.flags structseq. It exposes the status of
3206 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003207
Georg Brandl3ee81df2008-05-17 18:14:43 +00003208- Objects/structseq.c: Implemented new structseq representation. The
3209 patch makes structseqs (e.g. the return value of os.stat) more
3210 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003211
Georg Brandl3ee81df2008-05-17 18:14:43 +00003212- Patch #1700288: added a type attribute cache that caches method
3213 accesses, resulting in speedups in heavily object-oriented code.

3221 envvar and sys.dont_write_bytecode attribute. All these can be set
3222 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003223
Georg Brandl3ee81df2008-05-17 18:14:43 +00003224- Improve some exception messages when Windows fails to load an
3225 extension module. Now we get for example '%1 is not a valid Win32
3226 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003233- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234 and INF. float("nan"), float("inf") and float("-inf") now work on
3235 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003237- Compiler now generates simpler and faster code for dictionary
3238 literals. The oparg for BUILD_MAP now indicates an estimated
3239 dictionary size. There is a new opcode, STORE_MAP, for adding
3240 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003269- Patch #1739468: Directories and zipfiles containing a __main__.py
3270 file can now be directly executed by passing their name to the
3271 interpreter. The directory/zipfile is automatically inserted as the
3272 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003274- Issue #1265: Fix a problem with sys.settrace, if the tracing
3275 function uses a generator expression when at the same time the
3276 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003277
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003278- sets and frozensets now have an isdisjoint() method.

3283
Georg Brandl5a7eca12010-03-21 19:29:04 +00003284- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003285 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3286 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003287
Georg Brandl3ee81df2008-05-17 18:14:43 +00003288- Issue #1686386: Tuple's tp_repr did not take into account the
3289 possibility of having a self-referential tuple, which is possible
3290 from C code. Nor did object's tp_str consider that a type's tp_str
3291 could do something that could lead to an inifinite recursion.
3292 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3293 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003294
Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Issue #1164: It was possible to trigger deadlock when using the
3296 'print' statement to write to a file since the GIL was not released
3297 as needed. Now PyObject_Print() does the right thing along with
3298 various tp_print implementations of the built-in types and those in
3299 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003300
Georg Brandl3ee81df2008-05-17 18:14:43 +00003301- Issue #1147: Exceptions were directly allowing string exceptions in
3302 their throw() method even though string exceptions no longer
3303 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003305- Issue #1096: Prevent a segfault from getting the repr of a very
3306 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003307
Brett Cannon1e534b52007-09-07 04:18:30 +00003308- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003309 PyObject_Call() never calling back out to Python code to trigger
3310 recursion depth updates/checks. Required the creation of a static
3311 RuntimeError instance in case normalizing an exception put the
3312 recursion check value past its limit. Fixes crashers
3313 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003314

Neal Norwitz0ac60192007-05-27 04:08:54 +00003328- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003329 __*__ attributes. (Some already existed, e.g., __doc__ and
3330 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003331
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003332- Add -3 option to the interpreter to warn about features that are
3333 deprecated and will be changed/removed in Python 3.0.
3334
Georg Brandl2134e752007-05-21 20:34:16 +00003335- Patch #1686487: you can now pass any mapping after '**' in function
3336 calls.
3337
Collin Winter62903052007-05-18 23:11:24 +00003338- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003339 "except E as target:". This is to provide forwards compatibility
3340 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003341
Brett Cannon229cee22007-05-05 01:34:02 +00003342- Deprecate BaseException.message as per PEP 352.
3343
Georg Brandl3ee81df2008-05-17 18:14:43 +00003344- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003345 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003346
Vinay Sajip8549ce32007-05-06 17:53:37 +00003347- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003348 setting a plain string, ie don't expand to single letter identifiers.
3349
Raymond Hettinger13936692007-04-11 18:40:58 +00003350- Request #1191699: Slices can now be pickled.
3351
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003352- Request #1193128: str.translate() now allows a None argument for
3353 translations that only remove characters without re-mapping the
3354 remaining characters.
3355
Georg Brandl5cb76c12007-03-21 09:00:39 +00003356- Patch #1682205: a TypeError while unpacking an iterable is no longer
3357 masked by a generic one with the message "unpack non-sequence".
3358
Neal Norwitzaa754b72007-03-21 06:39:48 +00003359- Remove unused file Python/fmod.c.
3360
Guido van Rossum143b5642007-03-23 04:58:42 +00003361- Bug #1683368: The object.__init__() and object.__new__() methods are
3362 now stricter in rejecting excess arguments. The only time when
3363 either allows excess arguments is when it is not overridden and the
3364 other one is. For backwards compatibility, when both are
3365 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003366 warning later). Also, type.__init__() insists on the same signature
3367 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003368
Georg Brandl3ee81df2008-05-17 18:14:43 +00003369- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3370 object to complex using its __complex__() method before falling back
3371 to the __float__() method. Therefore, the functions in the cmath
3372 module now can operate on objects that define a __complex__()
3373 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003374
Georg Brandl3ee81df2008-05-17 18:14:43 +00003375- Patch #1623563: allow __class__ assignment for classes with
3376 __slots__. The old and the new class are still required to have the
3377 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003378

3383 ``object.__reduce_ex__()`` is called with an object that is faking
3384 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003385
Georg Brandl3ee81df2008-05-17 18:14:43 +00003386- Patch #1680015: Don't modify __slots__ tuple if it contains an

3390
Georg Brandl7b9c5552007-03-12 14:30:05 +00003391- Bug #1678647: write a newline after printing an exception in any
3392 case, even when converting the value to a string failed.
3393
Georg Brandl871f1bc2007-03-12 13:17:36 +00003394- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003395 its argument, if it exists. If not, it will work like before. This
3396 allows customizing the output of dir() in the presence of a
3397 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003398
Collin Winter276887b2007-03-12 16:11:39 +00003399- Patch #922167: Python no longer segfaults when faced with infinitely
3400 self-recursive reload() calls (as reported by bug #742342).
3401
Georg Brandl3ee81df2008-05-17 18:14:43 +00003402- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003405- Patch #1491866: change the complex() constructor to allow
3406 parthensized forms. This means complex(repr(x)) now works instead of
3407 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003408
Georg Brandlaa2321b2007-03-07 00:40:28 +00003409- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003410 makes the filenames the warning module prints much more sensible
3411 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003412

3414 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003415 variable is given, but break into the interactive interpreter just
3416 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003424- Patch #1674228: when assigning a slice (old-style), check for the
3425 sq_ass_slice instead of the sq_slice slot.
3426
Georg Brandl3ee81df2008-05-17 18:14:43 +00003427- When printing an unraisable error, don't print exceptions. before
3428 the name. This duplicates the behavior whening normally printing
3429 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003980- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl92a6bae2007-03-13 17:43:32 +00003996- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003997 are set for invalid interpolation sequences that would lead to
3998 errors on reading back those values.

4052

4054 TestCase and TestSuite subclasses (not instances) are no longer
4055 accepted in TestSuite.addTest(). This should cause no
4056 incompatibility since it never made sense with ordinary subclasses
4057 -- the failure just occurred later, with a more cumbersome
4058 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004345 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004347 does not claim to support starttls. Adds the
4348 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004446- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004447 time so that opening a database previously created with the DB_DUP
4448 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4449 opens. Specifically: dictionary assignment to a DB object will
4450 replace all values for a given key when the database allows
4451 duplicate values. DB users should use DB.put(k, v) when they want
4452 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004732 periodic threadstate and signal checking in tight loops. By
4733 default, this option is turned-off. It should only be enabled in

Georg Brandl3ee81df2008-05-17 18:14:43 +00004792- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4793 to ``PyTuple_SetItem``, it can be used to populate a brand new

4806
Georg Brandl3ee81df2008-05-17 18:14:43 +00004807- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4808 of w# format code incorrectly truncated the length to an int, even
4809 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4810 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004840- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4841 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
