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 Brandl0ba1f012010-08-01 22:00:39 +000038- Issue #4108: In urllib.robotparser, if there are multiple 'User-agent: *'
39 entries, consider the first one.
40
Georg Brandl86edb142010-08-01 21:58:18 +000041- Issue #9354: Provide getsockopt() in asyncore's file_wrapper.
42
Benjamin Peterson85633362010-06-08 14:58:25 +000043- In the unicode/str.format(), raise a ValueError when indexes to arguments are
44 too large.
Benjamin Petersonc9719132010-06-07 22:27:32 +000045
Victor Stinnerc3e40e02010-05-25 22:40:38 +000046- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
47 and error handler, instead of writing to the C stderr file in utf-8
48
Brett Cannon7d006262010-05-20 18:41:08 +000049- Issue #7902: When using explicit relative import syntax, don't try
50 implicit relative import semantics.
51
Antoine Pitrou5de15942010-05-17 20:00:52 +000052- Issue #7079: Fix a possible crash when closing a file object while using
53 it from another thread. Patch by Daniel Stutzbach.
54
Mark Dickinsone02c9d22010-05-07 13:23:18 +000055- Issue #1533: fix inconsistency in range function argument
56 processing: any non-float non-integer argument is now converted to
57 an integer (if possible) using its __int__ method. Previously, only
58 small arguments were treated this way; larger arguments (those whose
59 __int__ was outside the range of a C long) would produce a TypeError.
60
Benjamin Petersonc218ce82010-04-16 22:43:53 +000061- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

71- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
Victor Stinner4fd2ff92010-03-22 12:56:39 +000072
Victor Stinnerd156fa32010-03-21 13:32:31 +000073- Issue #7544: Preallocate thread memory before creating the thread to avoid
74 a fatal error in low memory condition.
75
Victor Stinner0217c952010-03-21 13:09:24 +000076- Issue #7820: The parser tokenizer restores all bytes in the right if
77 the BOM check fails.
78

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

93 reads on a BZ2File object, rather than returning incorrect results.
94
R. David Murray0d023db2010-08-01 04:11:05 +000095- Issue #8620: when a Cmd is fed input that reaches EOF without a final

1606What's New in Python 2.6.1
1607==========================
1608
1609*Release date: 04-Dec-2008*
1610
1611Core and Builtins
1612-----------------
1613
1614- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1615 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1616 instead of throwing a MemoryError.
1617
1618- Issue #4367: Python would segfault during compiling when the unicodedata
1619 module couldn't be imported and \N escapes were present.
1620
1621- Issue #4348: Some bytearray methods returned that didn't cause any change to
1622 the bytearray, returned the same bytearray instead of a copy.
1623
1624- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1625
1626- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1627
1628- Issue #4048: The parser module now correctly validates relative imports.
1629
1630- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1631 exec statement.

1633- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1634 method does not return iterators for the 4th and 5th items.
1635
1636- Issue #4209: Enabling unicode_literals and the print_function in the same
1637 __future__ import didn't work.
1638
1639- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1640 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1641 really executed because I cannot move to such directory on win2k)
1642
1643- Issue #4069: When set.remove(element) is used with a set element, the element
1644 is temporarily replaced with an equivalent frozenset. But the eventual
1645 KeyError would always report the empty frozenset([]) as the missing key. Now
1646 it correctly refers to the initial element.
1647
1648- Fixed C99 style comments in several files. Python is now C89 compatible
1649 again.

1797
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001798- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1799 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1800 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1801 ``printf`` function, whereas PyString_FromFormat has an independent
1802 implementation and uses "%zd" on all platforms for size_t values.
1803 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +00001824 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1825 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1827 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1828 type object.

1899 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1900 for catch_warnings() also led to an improvement in the raising of a
1901 DeprecationWarning related to warnings.warn_explicit().
1902
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001903- The deprecation warnings for the old camelCase threading API were removed.

1922
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001923- Issue #2975: When compiling several extension modules with Visual Studio 2008
1924 from the same python interpreter, some environment variables would grow
1925 without limit.
1926
Benjamin Peterson37346b22008-08-23 20:27:43 +00001927- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001964What's New in Python 2.6 beta 3?
1965================================
1966
Barry Warsaw07a4a382008-08-21 01:15:08 +00001967*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001968
1969Core and Builtins
1970-----------------
1971
Guido van Rossumf8402962008-08-20 15:01:50 +00001972- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1973 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1974 extensions do not automatically benefit from the class attribute
1975 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1976 to their tp_flags field if they care. This is a backwards
1977 compatibility feature; in 3.0, all types will use the cache by
1978 default.
1979
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001980- Keyword arguments can now follow starred arguments. (``f(a, *args,
1981 keyword=23)`` is now valid syntax.)
1982
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001983- ctypes function pointers that are COM methods have a boolean True
1984 value again.
1985
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001986- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1987 by denying s# to parse objects that have a releasebuffer procedure,
1988 and introducing s*.
1989
Georg Brandl1e13ea92008-08-11 09:07:59 +00001990- Issue #3537: Fix an assertion failure when an empty but presized dict
1991 object was stored in the freelist.
1992
Mark Dickinsonb6467572008-08-04 21:30:09 +00001993- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1994 ValueError consistently across platforms.
1995
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001996- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1997 (64bit Unix, for example), unichr() would truncate its argument and return
1998 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1999
Neal Norwitze7d8be82008-07-31 17:17:14 +00002000- Apply security patches from Apple.
2001
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002002- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2003 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2004
Antoine Pitrou92f82162008-07-25 22:22:08 +00002005- Issue #1819: function calls with several named parameters are now on
2006 average 35% faster (as measured by pybench).
2007
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002008- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2009 the python debugger steps into a class statement: the free variables (local
2010 variables defined in an outer scope) would be deleted from the outer scope.
2011
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002012- Issue #2620: Overflow checking when allocating or reallocating memory
2013 was not always being done properly in some python types and extension
2014 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2015 all been updated to perform better checks and places in the code that
2016 would previously leak memory on the error path when such an allocation
2017 failed have been fixed.
2018
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002019Library
2020-------
2021

2025 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2026
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002027- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2028 version reported by these tools does not necessarily follow the python
2029 version numbering scheme, so the module is less strict when parsing it.
2030
Nick Coghlanf70385a2008-08-18 12:42:46 +00002031- Issue #2235: Added Py3k warnings for types which will become unhashable
2032 under the stricter __hash__ inheritance rules in 3.0. Several types
2033 which did not meet the rules for hash invariants and were already
2034 unhashable in 3.0 have now been explicitly flagged as unhashable in
2035 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2036 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2037
Brett Cannon88f801d2008-08-18 00:46:22 +00002038- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2046
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002047- Issue #3575: Incremental decoder's decode function now takes bytearray
2048 by using 's*' instead of 't#'.
2049
Jesus Cea585ad8a2009-07-02 15:37:21 +00002050- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002051 fails unicode conversion on 2nd parameter. (windows only)
2052
Facundo Batista94f243a2008-08-17 03:38:39 +00002053- Issue 2464. urllib2 now supports a malformation in the URL received
2054 in a redirect.
2055
Brett Cannonabe423e2008-08-16 21:47:07 +00002056- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002057 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002058
Facundo Batistaeb90b782008-08-16 14:44:07 +00002059- Issue #2776: fixed small issue when handling an URL with double slash
2060 after a 302 response in the case of not going through a proxy.
2061
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002062- Issue #2676: in the email package, content-type parsing was hanging on
2063 pathological input because of quadratic or exponential behaviour of a
2064 regular expression.
2065
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002066- Issue #3476: binary buffered reading through the new "io" library is now
2067 thread-safe.
2068
Brett Cannonbf3157b2008-08-14 05:00:03 +00002069- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2070 since mimetools itself is deprecated. Because modules are cached, all
2071 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2072
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002073- Issue #3134: shutil referenced undefined WindowsError symbol.
2074
Robert Schuppenies14646332008-08-10 11:01:53 +00002075- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2076 menu entries were not deleted.
2077
Brett Cannon83e81842008-08-09 23:30:55 +00002078- Copied the implementation of reduce() to _functools.reduce() to have a
2079 version that did not raise a DeprecationWarning under -3.
2080
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002081- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2082 a MemoryError rather than silently stop the iteration.
2083
Guido van Rossum59ce9012008-08-09 14:55:34 +00002084- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2085 to _sre.compile() will now be rejected. This should not affect anybody
2086 since the re.compile() function never generates invalid re-bytecode.
2087
Skip Montanaroa032bf42008-08-08 22:52:51 +00002088- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002107 asking for a specific length. This problem only affected files opened
2108 using the new "io" module, not the built-in open() function.

Georg Brandl3e483f62008-07-16 22:57:41 +00002166- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2167 its methods now allow for items objects that can be converted to
2168 an integer using operator.index().
2169
Mark Dickinson64b7e502008-07-16 09:40:03 +00002170- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2171 produced a ValueError instead of giving the correct float.
2172
Eric Smitha5fa5a22008-07-16 00:11:49 +00002173- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2174 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2175
Mark Dickinson7103aa42008-07-15 19:08:33 +00002176- Issue #3008: the float type has a new instance method 'float.hex'
2177 and a new class method 'float.fromhex' to convert floating-point
2178 numbers to and from hexadecimal strings, respectively.
2179
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002180- Issue #2235: __hash__ is once again inherited by default. To allow
2181 collections.Hashable to remain meaningful in the presence of the
2182 default hash implementation (object.__hash__), it is now possible
2183 to explicit block inheritance of hash by setting __hash__=None at
2184 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2185 level.
2186
Nick Coghlanb028f502008-07-13 14:52:36 +00002187- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2188 the parent module cannot be found while performing an absolute import.
2189 This means that an incorrectly defined __package__ attribute will
2190 now only prevent relative imports in that module rather than causing
2191 all imports from that module to fail.
2192
Nick Coghlan14ff9942008-07-08 14:21:42 +00002193- Issue #2517: Allow unicode messages in Exceptions again by correctly
2194 bypassing the instance dictionary when looking up __unicode__ on
2195 new-style classes.
2196
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002197- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2198 set to a custom object whose write() method happens to install
2199 another file in sys.stdout.
2200
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002201- Issue #3088: Corrected a race condition in classes derived from
2202 threading.local: the first member set by a thread could be saved in
2203 another thread's dictionary.
2204
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002205- Issue #3004: Minor change to slice.indices(): the start and stop
2206 arguments are now treated identically, making the behaviour easier
2207 to describe and understand. For example, slice(None, -10,
2208 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2209 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2210 10, -1).
2211
Georg Brandl278fc502008-07-19 12:46:12 +00002212- Issue #3219: Calling a function with repeated keyword arguments,
2213 f(a=2, a=23), would not cause a syntax error. This was a regression
2214 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002215
Georg Brandl278fc502008-07-19 12:46:12 +00002216- Issue #2862: Make int and float freelist management consistent with
2217 other freelists. Changes their CompactFreeList apis into
2218 ClearFreeList apis and calls them via gc.collect().

2222
Thomas Heller57adf222008-08-14 19:10:48 +00002223- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2224 api functions without holding the GIL, which could lead to a fatal
2225 error when they failed.
2226
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002227- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2236 ForkingPickler.register() to resolve conflict with ctypes.
2237
Vinay Sajip51e65192008-07-18 09:01:10 +00002238- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002239

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002250- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002251
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002252- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2253 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002254 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002255 content-length. The problem had been corrected in the 2.4 branch, but never
2256 merged into trunk.
2257

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002271- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2272 handling is now the same as that of other special attributes like __name__).
2273
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002274- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002726- Issue #1631171: Re-implement the 'warnings' module in C (the
2727 original Python code has been kept as backup). This will allow for
2728 using the 'warning's machinery in such places as the parser where
2729 use of pure Python code is not possible. Both the ``showarning()``
2730 and ``formatwarning()`` gain an optional 'line' argument which is
2731 not called by default for backwards-compatibility reasons. Setting
2732 ``warnings.showwarning()`` to an implementation that lacks support
2733 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002796- Issue #2550: The approach used by client/server code for obtaining
2797 ports to listen on in network-oriented tests has been refined in an
2798 effort to facilitate running multiple instances of the entire
2799 regression test suite in parallel without issue.
2800 test_support.bind_port() has been fixed such that it will always
2801 return a unique port -- which wasn't always the case with the
2802 previous implementation, especially if socket options had been set
2803 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2804 new implementation of bind_port() will actually raise an exception
2805 if it is passed an AF_INET/SOCK_STREAM socket with either the
2806 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2807 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2808 the socket it's been passed. This currently only applies to
2809 Windows. This option prevents any other sockets from binding to the
2810 host/port we've bound to, thus removing the possibility of the
2811 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2812 when a second SOCK_STREAM socket binds and accepts to a host/port
2813 that's already been bound by another socket. The optional preferred
2814 port parameter to bind_port() has been removed. Under no
2815 circumstances should tests be hard coding ports!
2816
2817 test_support.find_unused_port() has also been introduced, which will
2818 pass a temporary socket object to bind_port() in order to obtain an
2819 unused port. The temporary socket object is then closed and
2820 deleted, and the port is returned. This method should only be used
2821 for obtaining an unused port in order to pass to an external program
2822 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2823 a parameter to a server-oriented class that doesn't give you direct
2824 access to the underlying socket used.
2825
2826 Finally, test_support.HOST has been introduced, which should be used
2827 for the host argument of any relevant socket calls (i.e. bind and
2828 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002829
2830 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002832 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2833 test_asynchat and test_socket_ssl.
2834
Georg Brandl3ee81df2008-05-17 18:14:43 +00002835 It is now possible for multiple instances of the regression test
2836 suite to run in parallel without issue.

2992 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002993 platform.machine() and platform.processor() will report this
2994 information as well.

3103-----------------
3104
Fred Drakea8ee94b2008-03-01 02:45:07 +00003105- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003106 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003107
Georg Brandlad61bc82008-02-23 15:11:18 +00003108- Issue #2067: file.__exit__() now calls subclasses' close() method.
3109
3110- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003111
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003112- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003113 issue 215555 for a discussion.
3114
Eric Smitha73fbe72008-02-23 03:09:44 +00003115- Added the future_builtins module, which contains hex() and oct().
3116 These are the PEP 3127 version of these functions, designed to be
3117 compatible with the hex() and oct() builtins from Python 3.0. They
3118 differ slightly in their output formats from the existing, unchanged
3119 Python 2.6 builtins. The expected usage of the future_builtins
3120 module is:
3121 from future_builtins import hex, oct
3122
Eric Smith7ef40bf2008-02-20 23:34:22 +00003123- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3124 exponents for exponents with absolute value < 100. Follows C99
3125 standard. This is a change on Windows, which would use 3 digits.
3126 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3127 so that any alterations it does to the resulting string will be
3128 available in stringlib/formatter.h (for float.__format__).
3129
Eric Smith5a3c1352008-02-19 13:21:56 +00003130- Implemented PEP 3101, Advanced String Formatting. This adds a new
3131 builtin format(); a format() method for str and unicode; a
3132 __format__() method to object, str, unicode, int, long, float, and
3133 datetime; the class string.Formatter; and the C API
3134 PyObject_Format().
3135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Fixed several potential crashes, all caused by specially crafted
3137 __del__ methods exploiting objects in temporarily inconsistent
3138 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003139
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003140- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003141 prevent a possible crash: an Abstract Base Class would try to access
3142 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003143
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144- Fixed repr() and str() of complex numbers with infinity or nan as
3145 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003146
Georg Brandl3ee81df2008-05-17 18:14:43 +00003147- Clear all free lists during a gc.collect() of the highest generation
3148 in order to allow pymalloc to free more arenas. Python may give back
3149 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003150
Georg Brandl3ee81df2008-05-17 18:14:43 +00003151- Issue #2045: Fix an infinite recursion triggered when printing a
3152 subclass of collections.defaultdict, if its default_factory is set
3153 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003154
Christian Heimesf75dbef2008-02-08 00:11:31 +00003155- Fixed a minor memory leak in dictobject.c. The content of the free
3156 list was not freed on interpreter shutdown.
3157
Georg Brandl5a7eca12010-03-21 19:29:04 +00003158- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003159 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3162 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003163 to compact the internal free lists of pre-allocted ints and floats.
3164
Georg Brandl3ee81df2008-05-17 18:14:43 +00003165- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3166 calls. Python expected the return type int but the fork familie
3167 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003168
Georg Brandl3ee81df2008-05-17 18:14:43 +00003169- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3170 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003171
Georg Brandl3ee81df2008-05-17 18:14:43 +00003172- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3173 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003174
Georg Brandl3ee81df2008-05-17 18:14:43 +00003175- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3176 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00003178- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3179 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003180
Georg Brandl3ee81df2008-05-17 18:14:43 +00003181- Patch #1473257: generator objects gain a gi_code attribute. This is
3182 the same object as the func_code attribute of the function that
3183 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Issue #1920: "while 0" statements were completely removed by the
3186 compiler, even in the presence of an "else" clause, which is
3187 supposed to be run when the condition is false. Now the compiler
3188 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003189
Guido van Rossumeead05f2008-01-24 18:21:02 +00003190- A few crashers fixed: weakref_in_del.py (issue #1377858);
3191 loosing_dict_ref.py (issue #1303614, test67.py);
3192 borrowed_ref_[34].py (not in tracker).
3193
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003194- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003195 suppressed while an extension is loaded by calling SetErrorMode in
3196 dynload_win.c. The error is still reported properly.
3197
Georg Brandl3ee81df2008-05-17 18:14:43 +00003198- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003199 several extension methods and modules do not work without unicode
3200 support.
3201
Georg Brandl26543b12008-01-21 18:36:51 +00003202- Issue #1882: when compiling code from a string, encoding cookies in the
3203 second line of code were not always recognized correctly.
3204
Georg Brandl14404b62008-01-19 19:27:05 +00003205- Issue #1679: "0x" was taken as a valid integer literal.
3206
Georg Brandl6caad7d2008-01-26 14:19:22 +00003207- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003208 added.
3209
Christian Heimesc94e2b52008-01-14 04:13:37 +00003210- sys.float_info / PyFloat_GetInfo: The floating point information
3211 object was converted from a dict to a specialized structseq object.
3212
Georg Brandl3ee81df2008-05-17 18:14:43 +00003213- Patch #1816: Added sys.flags structseq. It exposes the status of
3214 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003215
Georg Brandl3ee81df2008-05-17 18:14:43 +00003216- Objects/structseq.c: Implemented new structseq representation. The
3217 patch makes structseqs (e.g. the return value of os.stat) more
3218 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003219
Georg Brandl3ee81df2008-05-17 18:14:43 +00003220- Patch #1700288: added a type attribute cache that caches method
3221 accesses, resulting in speedups in heavily object-oriented code.

3229 envvar and sys.dont_write_bytecode attribute. All these can be set
3230 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003231
Georg Brandl3ee81df2008-05-17 18:14:43 +00003232- Improve some exception messages when Windows fails to load an
3233 extension module. Now we get for example '%1 is not a valid Win32
3234 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003241- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003242 and INF. float("nan"), float("inf") and float("-inf") now work on
3243 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003245- Compiler now generates simpler and faster code for dictionary
3246 literals. The oparg for BUILD_MAP now indicates an estimated
3247 dictionary size. There is a new opcode, STORE_MAP, for adding
3248 entries to the dictionary.

3278 file can now be directly executed by passing their name to the
3279 interpreter. The directory/zipfile is automatically inserted as the
3280 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003282- Issue #1265: Fix a problem with sys.settrace, if the tracing
3283 function uses a generator expression when at the same time the
3284 executed code is closing a paused generator.

3291
Georg Brandl5a7eca12010-03-21 19:29:04 +00003292- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003293 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3294 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003295
Georg Brandl3ee81df2008-05-17 18:14:43 +00003296- Issue #1686386: Tuple's tp_repr did not take into account the
3297 possibility of having a self-referential tuple, which is possible
3298 from C code. Nor did object's tp_str consider that a type's tp_str
3299 could do something that could lead to an inifinite recursion.
3300 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3301 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003302
Georg Brandl3ee81df2008-05-17 18:14:43 +00003303- Issue #1164: It was possible to trigger deadlock when using the
3304 'print' statement to write to a file since the GIL was not released
3305 as needed. Now PyObject_Print() does the right thing along with
3306 various tp_print implementations of the built-in types and those in
3307 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003308
Georg Brandl3ee81df2008-05-17 18:14:43 +00003309- Issue #1147: Exceptions were directly allowing string exceptions in

3311 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00003315
Brett Cannon1e534b52007-09-07 04:18:30 +00003316- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003317 PyObject_Call() never calling back out to Python code to trigger
3318 recursion depth updates/checks. Required the creation of a static
3319 RuntimeError instance in case normalizing an exception put the
3320 recursion check value past its limit. Fixes crashers
3321 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003322

Neal Norwitz0ac60192007-05-27 04:08:54 +00003336- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003337 __*__ attributes. (Some already existed, e.g., __doc__ and
3338 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003339
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003340- Add -3 option to the interpreter to warn about features that are
3341 deprecated and will be changed/removed in Python 3.0.
3342
Georg Brandl2134e752007-05-21 20:34:16 +00003343- Patch #1686487: you can now pass any mapping after '**' in function
3344 calls.
3345
Collin Winter62903052007-05-18 23:11:24 +00003346- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003347 "except E as target:". This is to provide forwards compatibility
3348 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003349
Brett Cannon229cee22007-05-05 01:34:02 +00003350- Deprecate BaseException.message as per PEP 352.
3351
Georg Brandl3ee81df2008-05-17 18:14:43 +00003352- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003353 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003354
Vinay Sajip8549ce32007-05-06 17:53:37 +00003355- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003356 setting a plain string, ie don't expand to single letter identifiers.
3357
Raymond Hettinger13936692007-04-11 18:40:58 +00003358- Request #1191699: Slices can now be pickled.
3359
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003360- Request #1193128: str.translate() now allows a None argument for
3361 translations that only remove characters without re-mapping the
3362 remaining characters.
3363
Georg Brandl5cb76c12007-03-21 09:00:39 +00003364- Patch #1682205: a TypeError while unpacking an iterable is no longer
3365 masked by a generic one with the message "unpack non-sequence".
3366
Neal Norwitzaa754b72007-03-21 06:39:48 +00003367- Remove unused file Python/fmod.c.
3368
Guido van Rossum143b5642007-03-23 04:58:42 +00003369- Bug #1683368: The object.__init__() and object.__new__() methods are
3370 now stricter in rejecting excess arguments. The only time when
3371 either allows excess arguments is when it is not overridden and the
3372 other one is. For backwards compatibility, when both are
3373 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003374 warning later). Also, type.__init__() insists on the same signature
3375 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003376
Georg Brandl3ee81df2008-05-17 18:14:43 +00003377- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3378 object to complex using its __complex__() method before falling back
3379 to the __float__() method. Therefore, the functions in the cmath
3380 module now can operate on objects that define a __complex__()
3381 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003382
Georg Brandl3ee81df2008-05-17 18:14:43 +00003383- Patch #1623563: allow __class__ assignment for classes with
3384 __slots__. The old and the new class are still required to have the
3385 same slot names.

3391 ``object.__reduce_ex__()`` is called with an object that is faking
3392 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003393
Georg Brandl3ee81df2008-05-17 18:14:43 +00003394- Patch #1680015: Don't modify __slots__ tuple if it contains an

3398
Georg Brandl7b9c5552007-03-12 14:30:05 +00003399- Bug #1678647: write a newline after printing an exception in any
3400 case, even when converting the value to a string failed.
3401
Georg Brandl871f1bc2007-03-12 13:17:36 +00003402- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003403 its argument, if it exists. If not, it will work like before. This
3404 allows customizing the output of dir() in the presence of a
3405 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003406
Collin Winter276887b2007-03-12 16:11:39 +00003407- Patch #922167: Python no longer segfaults when faced with infinitely
3408 self-recursive reload() calls (as reported by bug #742342).
3409
Georg Brandl3ee81df2008-05-17 18:14:43 +00003410- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003413- Patch #1491866: change the complex() constructor to allow
3414 parthensized forms. This means complex(repr(x)) now works instead of
3415 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003416
Georg Brandlaa2321b2007-03-07 00:40:28 +00003417- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003418 makes the filenames the warning module prints much more sensible
3419 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003420

3422 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423 variable is given, but break into the interactive interpreter just
3424 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00003431
Georg Brandl0fca97a2007-03-05 22:28:08 +00003432- Patch #1674228: when assigning a slice (old-style), check for the
3433 sq_ass_slice instead of the sq_slice slot.
3434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- When printing an unraisable error, don't print exceptions. before
3436 the name. This duplicates the behavior whening normally printing
3437 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003988- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl92a6bae2007-03-13 17:43:32 +00004004- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004005 are set for invalid interpolation sequences that would lead to

4062 TestCase and TestSuite subclasses (not instances) are no longer
4063 accepted in TestSuite.addTest(). This should cause no
4064 incompatibility since it never made sense with ordinary subclasses
4065 -- the failure just occurred later, with a more cumbersome
4066 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004353 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004355 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004454- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004455 time so that opening a database previously created with the DB_DUP
4456 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4457 opens. Specifically: dictionary assignment to a DB object will
4458 replace all values for a given key when the database allows
4459 duplicate values. DB users should use DB.put(k, v) when they want
4460 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004740 periodic threadstate and signal checking in tight loops. By
4741 default, this option is turned-off. It should only be enabled in

4814
Georg Brandl3ee81df2008-05-17 18:14:43 +00004815- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4816 of w# format code incorrectly truncated the length to an int, even
4817 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4818 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004848- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4849 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
