652What's New in Python 2.6.1
653==========================
654
655*Release date: 04-Dec-2008*
656
657Core and Builtins
658-----------------
659
660- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
661 interpreter to abort ("Fatal Python error: Could not reset the stack!")
662 instead of throwing a MemoryError.
663
664- Issue #4367: Python would segfault during compiling when the unicodedata
665 module couldn't be imported and \N escapes were present.
666
667- Issue #4348: Some bytearray methods returned that didn't cause any change to
668 the bytearray, returned the same bytearray instead of a copy.
669
670- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
671
672- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
673
674- Issue #4048: The parser module now correctly validates relative imports.
675
676- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
677 exec statement.
678
679- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
680 method does not return iterators for the 4th and 5th items.
681
682- Issue #4209: Enabling unicode_literals and the print_function in the same
683 __future__ import didn't work.
684
685- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
686 returned a path longer than MAX_PATH. (But It's doubtful this code path is
687 really executed because I cannot move to such directory on win2k)
688
689- Issue #4069: When set.remove(element) is used with a set element, the element
690 is temporarily replaced with an equivalent frozenset. But the eventual
691 KeyError would always report the empty frozenset([]) as the missing key. Now
692 it correctly refers to the initial element.
693
694- Fixed C99 style comments in several files. Python is now C89 compatible
695 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000842- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
843
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000844- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
845 PyString_FromFormat or PyErr_Format to display size_t values. The macro
846 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
847 ``printf`` function, whereas PyString_FromFormat has an independent
848 implementation and uses "%zd" on all platforms for size_t values.
849 This makes a difference on win64, where ``printf`` needs "%Id" to display
850 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +0000852- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

868
Vinay Sajip35e3b032008-09-01 14:33:59 +0000869- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000870 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
871 mechanism. In the process, fix a bug where isinstance() and issubclass(),
872 when given a tuple of classes as second argument, were looking up
873 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
874 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001010What's New in Python 2.6 beta 3?
1011================================
1012
Barry Warsaw07a4a382008-08-21 01:15:08 +00001013*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001014
1015Core and Builtins
1016-----------------
1017
Guido van Rossumf8402962008-08-20 15:01:50 +00001018- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1019 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1020 extensions do not automatically benefit from the class attribute
1021 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1022 to their tp_flags field if they care. This is a backwards
1023 compatibility feature; in 3.0, all types will use the cache by
1024 default.
1025
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001026- Keyword arguments can now follow starred arguments. (``f(a, *args,
1027 keyword=23)`` is now valid syntax.)
1028
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001029- ctypes function pointers that are COM methods have a boolean True
1030 value again.
1031
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001032- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1033 by denying s# to parse objects that have a releasebuffer procedure,
1034 and introducing s*.
1035
Georg Brandl1e13ea92008-08-11 09:07:59 +00001036- Issue #3537: Fix an assertion failure when an empty but presized dict
1037 object was stored in the freelist.
1038
Mark Dickinsonb6467572008-08-04 21:30:09 +00001039- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1040 ValueError consistently across platforms.
1041
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001042- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1043 (64bit Unix, for example), unichr() would truncate its argument and return
1044 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1045
Neal Norwitze7d8be82008-07-31 17:17:14 +00001046- Apply security patches from Apple.
1047
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001048- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1049 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1050
Antoine Pitrou92f82162008-07-25 22:22:08 +00001051- Issue #1819: function calls with several named parameters are now on
1052 average 35% faster (as measured by pybench).
1053
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001054- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1055 the python debugger steps into a class statement: the free variables (local
1056 variables defined in an outer scope) would be deleted from the outer scope.
1057
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001058- Issue #2620: Overflow checking when allocating or reallocating memory
1059 was not always being done properly in some python types and extension
1060 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1061 all been updated to perform better checks and places in the code that
1062 would previously leak memory on the error path when such an allocation
1063 failed have been fixed.
1064
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001065Library
1066-------
1067
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001068- Issue #3612: Added some missing basic types in ctypes.wintypes.
1069
Benjamin Petersone977ad42008-08-20 01:42:01 +00001070- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1071 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1072
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001073- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1074 version reported by these tools does not necessarily follow the python
1075 version numbering scheme, so the module is less strict when parsing it.
1076
Nick Coghlanf70385a2008-08-18 12:42:46 +00001077- Issue #2235: Added Py3k warnings for types which will become unhashable
1078 under the stricter __hash__ inheritance rules in 3.0. Several types
1079 which did not meet the rules for hash invariants and were already
1080 unhashable in 3.0 have now been explicitly flagged as unhashable in
1081 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1082 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1083
Brett Cannon88f801d2008-08-18 00:46:22 +00001084- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1085 imported into the module but exposed as part of the module's API.
1086
Brett Cannon7b96f072008-08-18 00:41:11 +00001087- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1088
Brett Cannon46225e72008-08-18 00:36:52 +00001089- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1090
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001091- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1092
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001093- Issue #3575: Incremental decoder's decode function now takes bytearray
1094 by using 's*' instead of 't#'.
1095
Jesus Cea585ad8a2009-07-02 15:37:21 +00001096- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001097 fails unicode conversion on 2nd parameter. (windows only)
1098
Facundo Batista94f243a2008-08-17 03:38:39 +00001099- Issue 2464. urllib2 now supports a malformation in the URL received
1100 in a redirect.
1101
Brett Cannonabe423e2008-08-16 21:47:07 +00001102- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001103 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001104
Facundo Batistaeb90b782008-08-16 14:44:07 +00001105- Issue #2776: fixed small issue when handling an URL with double slash
1106 after a 302 response in the case of not going through a proxy.
1107
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001108- Issue #2676: in the email package, content-type parsing was hanging on
1109 pathological input because of quadratic or exponential behaviour of a
1110 regular expression.
1111
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001112- Issue #3476: binary buffered reading through the new "io" library is now
1113 thread-safe.
1114
Brett Cannonbf3157b2008-08-14 05:00:03 +00001115- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1116 since mimetools itself is deprecated. Because modules are cached, all
1117 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1118
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001119- Issue #3134: shutil referenced undefined WindowsError symbol.
1120
Robert Schuppenies14646332008-08-10 11:01:53 +00001121- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1122 menu entries were not deleted.
1123
Brett Cannon83e81842008-08-09 23:30:55 +00001124- Copied the implementation of reduce() to _functools.reduce() to have a
1125 version that did not raise a DeprecationWarning under -3.
1126
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001127- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1128 a MemoryError rather than silently stop the iteration.
1129
Guido van Rossum59ce9012008-08-09 14:55:34 +00001130- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1131 to _sre.compile() will now be rejected. This should not affect anybody
1132 since the re.compile() function never generates invalid re-bytecode.
1133
Skip Montanaroa032bf42008-08-08 22:52:51 +00001134- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1135 upon first access it can be automatically initialized from the csv file if
1136 it wasn't initialized during instantiation.
1137
Brett Cannon3aa2a492008-08-06 22:28:09 +00001138- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1139 the reload() built-in has been removed.
1140
Brett Cannon7e30b672008-08-04 21:52:25 +00001141- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001142 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1146 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1147 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001148
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001149- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1150 raised an AttributeError.
1151
Benjamin Peterson01a24322008-07-28 23:35:27 +00001152- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001153 asking for a specific length. This problem only affected files opened
1154 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001155
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001156- Issue #3449: Update decimal module to use most recent specification
1157 (v. 1.68) and tests (v. 2.58) from IBM.
1158
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001159- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1160
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001161- Issue 1592: Improve error reporting when operations are attempted
1162 on a closed shelf.

1165
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001166- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1167
1168- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1169 invalid arguments.
1170
1171- Issue #3302: Fix several crashes when calling locale's gettext functions
1172 with None arguments.
1173
1174- Issue #3389: Allow resolving dotted names for handlers in logging
1175 configuration files.
1176
1177- Deprecate the sunaudio module for removal in Python 3.0.
1178
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001179- Issue #3394: zipfile.writestr sets external attributes when passed a
1180 file name rather than a ZipInfo instance, so files are extracted with
1181 mode 0600 rather than 000 under Unix.
1182
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001183- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1184 argument in python 2.5, this broke code that subclassed Popen to include its
1185 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001195- Issue #2235: the C API function PyObject_HashNotImplemented and its
1196 interaction with the tp_hash slot (added in 2.6b2) are now documented
1197
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001198- Issue #643841: The language reference now provides more detailed
1199 coverage of the lookup process for special methods. The disclaimers
1200 regarding lack of coverage of new-style classes have also been
1201 removed, since the coverage is now fairly reasonable.

1210-----------------
1211
Georg Brandl3e483f62008-07-16 22:57:41 +00001212- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1213 its methods now allow for items objects that can be converted to
1214 an integer using operator.index().
1215
Mark Dickinson64b7e502008-07-16 09:40:03 +00001216- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1217 produced a ValueError instead of giving the correct float.
1218
Eric Smitha5fa5a22008-07-16 00:11:49 +00001219- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1220 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1221
Mark Dickinson7103aa42008-07-15 19:08:33 +00001222- Issue #3008: the float type has a new instance method 'float.hex'
1223 and a new class method 'float.fromhex' to convert floating-point
1224 numbers to and from hexadecimal strings, respectively.
1225
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001226- Issue #2235: __hash__ is once again inherited by default. To allow
1227 collections.Hashable to remain meaningful in the presence of the
1228 default hash implementation (object.__hash__), it is now possible
1229 to explicit block inheritance of hash by setting __hash__=None at
1230 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1231 level.
1232
Nick Coghlanb028f502008-07-13 14:52:36 +00001233- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1234 the parent module cannot be found while performing an absolute import.
1235 This means that an incorrectly defined __package__ attribute will
1236 now only prevent relative imports in that module rather than causing
1237 all imports from that module to fail.
1238
Nick Coghlan14ff9942008-07-08 14:21:42 +00001239- Issue #2517: Allow unicode messages in Exceptions again by correctly
1240 bypassing the instance dictionary when looking up __unicode__ on
1241 new-style classes.
1242
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001243- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1244 set to a custom object whose write() method happens to install
1245 another file in sys.stdout.
1246
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001247- Issue #3088: Corrected a race condition in classes derived from

1249 another thread's dictionary.
1250
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001251- Issue #3004: Minor change to slice.indices(): the start and stop
1252 arguments are now treated identically, making the behaviour easier
1253 to describe and understand. For example, slice(None, -10,
1254 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1255 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1256 10, -1).
1257
Georg Brandl278fc502008-07-19 12:46:12 +00001258- Issue #3219: Calling a function with repeated keyword arguments,
1259 f(a=2, a=23), would not cause a syntax error. This was a regression
1260 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00001710 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001711
1712 This is controlled by the configure argument ``--with-universal-archs``:
1713
1714 - ``--with-universal-archs=all``: install 4-way universal
1715
1716 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1717
1718 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1719
1720 This option should be used in combination with ``--enable-universalsdk=``.

1759 two handlers that derive the same default base class.

Christian Heimese74c8f22008-04-19 02:23:57 +00001761- Added kill, terminate and send_signal(sig) to subprocess.Popen.
1762

Georg Brandl3ee81df2008-05-17 18:14:43 +00001772- Issue #1631171: Re-implement the 'warnings' module in C (the
1773 original Python code has been kept as backup). This will allow for
1774 using the 'warning's machinery in such places as the parser where
1775 use of pure Python code is not possible. Both the ``showarning()``
1776 and ``formatwarning()`` gain an optional 'line' argument which is
1777 not called by default for backwards-compatibility reasons. Setting
1778 ``warnings.showwarning()`` to an implementation that lacks support
1779 for the ``line`` argument will raise a DeprecationWarning.

1803
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001804- The getpass module has been improved on Unix. It now uses /dev/tty
1805 by default and uses stderr instead of stdout. A GetPassWarning is
1806 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001842- Issue #2550: The approach used by client/server code for obtaining
1843 ports to listen on in network-oriented tests has been refined in an
1844 effort to facilitate running multiple instances of the entire
1845 regression test suite in parallel without issue.
1846 test_support.bind_port() has been fixed such that it will always
1847 return a unique port -- which wasn't always the case with the
1848 previous implementation, especially if socket options had been set
1849 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1850 new implementation of bind_port() will actually raise an exception
1851 if it is passed an AF_INET/SOCK_STREAM socket with either the
1852 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1853 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1854 the socket it's been passed. This currently only applies to
1855 Windows. This option prevents any other sockets from binding to the
1856 host/port we've bound to, thus removing the possibility of the
1857 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1858 when a second SOCK_STREAM socket binds and accepts to a host/port
1859 that's already been bound by another socket. The optional preferred
1860 port parameter to bind_port() has been removed. Under no
1861 circumstances should tests be hard coding ports!
1862
1863 test_support.find_unused_port() has also been introduced, which will
1864 pass a temporary socket object to bind_port() in order to obtain an
1865 unused port. The temporary socket object is then closed and
1866 deleted, and the port is returned. This method should only be used
1867 for obtaining an unused port in order to pass to an external program
1868 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1869 a parameter to a server-oriented class that doesn't give you direct
1870 access to the underlying socket used.
1871
1872 Finally, test_support.HOST has been introduced, which should be used
1873 for the host argument of any relevant socket calls (i.e. bind and
1874 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001875
1876 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001877 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001878 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1879 test_asynchat and test_socket_ssl.
1880
Georg Brandl3ee81df2008-05-17 18:14:43 +00001881 It is now possible for multiple instances of the regression test
1882 suite to run in parallel without issue.

2149-----------------
2150
Fred Drakea8ee94b2008-03-01 02:45:07 +00002151- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002152 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002153
Georg Brandlad61bc82008-02-23 15:11:18 +00002154- Issue #2067: file.__exit__() now calls subclasses' close() method.
2155
2156- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002157
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002158- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002159 issue 215555 for a discussion.
2160
Eric Smitha73fbe72008-02-23 03:09:44 +00002161- Added the future_builtins module, which contains hex() and oct().
2162 These are the PEP 3127 version of these functions, designed to be
2163 compatible with the hex() and oct() builtins from Python 3.0. They
2164 differ slightly in their output formats from the existing, unchanged
2165 Python 2.6 builtins. The expected usage of the future_builtins
2166 module is:
2167 from future_builtins import hex, oct
2168
Eric Smith7ef40bf2008-02-20 23:34:22 +00002169- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2170 exponents for exponents with absolute value < 100. Follows C99
2171 standard. This is a change on Windows, which would use 3 digits.
2172 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2173 so that any alterations it does to the resulting string will be
2174 available in stringlib/formatter.h (for float.__format__).
2175
Eric Smith5a3c1352008-02-19 13:21:56 +00002176- Implemented PEP 3101, Advanced String Formatting. This adds a new
2177 builtin format(); a format() method for str and unicode; a
2178 __format__() method to object, str, unicode, int, long, float, and
2179 datetime; the class string.Formatter; and the C API
2180 PyObject_Format().
2181
Georg Brandl3ee81df2008-05-17 18:14:43 +00002182- Fixed several potential crashes, all caused by specially crafted
2183 __del__ methods exploiting objects in temporarily inconsistent
2184 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002185
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002186- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002187 prevent a possible crash: an Abstract Base Class would try to access
2188 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002189
Georg Brandl3ee81df2008-05-17 18:14:43 +00002190- Fixed repr() and str() of complex numbers with infinity or nan as
2191 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002192
Georg Brandl3ee81df2008-05-17 18:14:43 +00002193- Clear all free lists during a gc.collect() of the highest generation
2194 in order to allow pymalloc to free more arenas. Python may give back
2195 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002196
Georg Brandl3ee81df2008-05-17 18:14:43 +00002197- Issue #2045: Fix an infinite recursion triggered when printing a
2198 subclass of collections.defaultdict, if its default_factory is set
2199 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002200
Christian Heimesf75dbef2008-02-08 00:11:31 +00002201- Fixed a minor memory leak in dictobject.c. The content of the free
2202 list was not freed on interpreter shutdown.
2203
Georg Brandl3ee81df2008-05-17 18:14:43 +00002204- Limit free list of method and builtin function objects to 256
2205 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002206
Georg Brandl3ee81df2008-05-17 18:14:43 +00002207- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2208 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002209 to compact the internal free lists of pre-allocted ints and floats.
2210
Georg Brandl3ee81df2008-05-17 18:14:43 +00002211- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2212 calls. Python expected the return type int but the fork familie
2213 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002214
Georg Brandl3ee81df2008-05-17 18:14:43 +00002215- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2216 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002217
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2219 with the collections.Sequence API.

2225 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002226
Georg Brandl3ee81df2008-05-17 18:14:43 +00002227- Patch #1473257: generator objects gain a gi_code attribute. This is
2228 the same object as the func_code attribute of the function that
2229 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002230
Georg Brandl3ee81df2008-05-17 18:14:43 +00002231- Issue #1920: "while 0" statements were completely removed by the
2232 compiler, even in the presence of an "else" clause, which is
2233 supposed to be run when the condition is false. Now the compiler
2234 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002235
Guido van Rossumeead05f2008-01-24 18:21:02 +00002236- A few crashers fixed: weakref_in_del.py (issue #1377858);
2237 loosing_dict_ref.py (issue #1303614, test67.py);
2238 borrowed_ref_[34].py (not in tracker).
2239
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002240- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002241 suppressed while an extension is loaded by calling SetErrorMode in
2242 dynload_win.c. The error is still reported properly.
2243
Georg Brandl3ee81df2008-05-17 18:14:43 +00002244- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002245 several extension methods and modules do not work without unicode
2246 support.
2247
Georg Brandl26543b12008-01-21 18:36:51 +00002248- Issue #1882: when compiling code from a string, encoding cookies in the
2249 second line of code were not always recognized correctly.
2250
Georg Brandl14404b62008-01-19 19:27:05 +00002251- Issue #1679: "0x" was taken as a valid integer literal.
2252
Georg Brandl6caad7d2008-01-26 14:19:22 +00002253- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002254 added.
2255
Christian Heimesc94e2b52008-01-14 04:13:37 +00002256- sys.float_info / PyFloat_GetInfo: The floating point information
2257 object was converted from a dict to a specialized structseq object.
2258
Georg Brandl3ee81df2008-05-17 18:14:43 +00002259- Patch #1816: Added sys.flags structseq. It exposes the status of
2260 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002261
Georg Brandl3ee81df2008-05-17 18:14:43 +00002262- Objects/structseq.c: Implemented new structseq representation. The
2263 patch makes structseqs (e.g. the return value of os.stat) more
2264 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002265
Georg Brandl3ee81df2008-05-17 18:14:43 +00002266- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002278- Improve some exception messages when Windows fails to load an
2279 extension module. Now we get for example '%1 is not a valid Win32
2280 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002288 and INF. float("nan"), float("inf") and float("-inf") now work on
2289 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002290
Georg Brandl3ee81df2008-05-17 18:14:43 +00002291- Compiler now generates simpler and faster code for dictionary
2292 literals. The oparg for BUILD_MAP now indicates an estimated
2293 dictionary size. There is a new opcode, STORE_MAP, for adding
2294 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002328- Issue #1265: Fix a problem with sys.settrace, if the tracing
2329 function uses a generator expression when at the same time the
2330 executed code is closing a paused generator.

2335
Neal Norwitz44f326e2007-10-05 05:29:17 +00002336- Fix warnings found by the new version of the Coverity checker.
2337
Georg Brandl3ee81df2008-05-17 18:14:43 +00002338- The enumerate() builtin function is no longer bounded to sequences
2339 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2340 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002341
Georg Brandl3ee81df2008-05-17 18:14:43 +00002342- Issue #1686386: Tuple's tp_repr did not take into account the
2343 possibility of having a self-referential tuple, which is possible
2344 from C code. Nor did object's tp_str consider that a type's tp_str
2345 could do something that could lead to an inifinite recursion.
2346 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2347 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002348
Georg Brandl3ee81df2008-05-17 18:14:43 +00002349- Issue #1164: It was possible to trigger deadlock when using the
2350 'print' statement to write to a file since the GIL was not released
2351 as needed. Now PyObject_Print() does the right thing along with
2352 various tp_print implementations of the built-in types and those in
2353 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002354
Georg Brandl3ee81df2008-05-17 18:14:43 +00002355- Issue #1147: Exceptions were directly allowing string exceptions in
2356 their throw() method even though string exceptions no longer
2357 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002358
Georg Brandl3ee81df2008-05-17 18:14:43 +00002359- Issue #1096: Prevent a segfault from getting the repr of a very
2360 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002361
Brett Cannon1e534b52007-09-07 04:18:30 +00002362- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002363 PyObject_Call() never calling back out to Python code to trigger
2364 recursion depth updates/checks. Required the creation of a static
2365 RuntimeError instance in case normalizing an exception put the
2366 recursion check value past its limit. Fixes crashers
2367 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002368

Neal Norwitz0ac60192007-05-27 04:08:54 +00002382- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002383 __*__ attributes. (Some already existed, e.g., __doc__ and
2384 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002385
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002386- Add -3 option to the interpreter to warn about features that are
2387 deprecated and will be changed/removed in Python 3.0.
2388
Georg Brandl2134e752007-05-21 20:34:16 +00002389- Patch #1686487: you can now pass any mapping after '**' in function
2390 calls.
2391
Collin Winter62903052007-05-18 23:11:24 +00002392- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002393 "except E as target:". This is to provide forwards compatibility
2394 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002395
Brett Cannon229cee22007-05-05 01:34:02 +00002396- Deprecate BaseException.message as per PEP 352.
2397
Georg Brandl3ee81df2008-05-17 18:14:43 +00002398- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002399 inherited from a builtin base.
2400
Vinay Sajip8549ce32007-05-06 17:53:37 +00002401- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002402 setting a plain string, ie don't expand to single letter identifiers.
2403
Raymond Hettinger13936692007-04-11 18:40:58 +00002404- Request #1191699: Slices can now be pickled.
2405
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002406- Request #1193128: str.translate() now allows a None argument for
2407 translations that only remove characters without re-mapping the
2408 remaining characters.
2409
Georg Brandl5cb76c12007-03-21 09:00:39 +00002410- Patch #1682205: a TypeError while unpacking an iterable is no longer
2411 masked by a generic one with the message "unpack non-sequence".
2412
Neal Norwitzaa754b72007-03-21 06:39:48 +00002413- Remove unused file Python/fmod.c.
2414
Guido van Rossum143b5642007-03-23 04:58:42 +00002415- Bug #1683368: The object.__init__() and object.__new__() methods are
2416 now stricter in rejecting excess arguments. The only time when
2417 either allows excess arguments is when it is not overridden and the
2418 other one is. For backwards compatibility, when both are
2419 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002420 warning later). Also, type.__init__() insists on the same signature
2421 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002422
Georg Brandl3ee81df2008-05-17 18:14:43 +00002423- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2424 object to complex using its __complex__() method before falling back
2425 to the __float__() method. Therefore, the functions in the cmath
2426 module now can operate on objects that define a __complex__()
2427 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002428
Georg Brandl3ee81df2008-05-17 18:14:43 +00002429- Patch #1623563: allow __class__ assignment for classes with
2430 __slots__. The old and the new class are still required to have the
2431 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002432

2437 ``object.__reduce_ex__()`` is called with an object that is faking
2438 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002439
Georg Brandl3ee81df2008-05-17 18:14:43 +00002440- Patch #1680015: Don't modify __slots__ tuple if it contains an

2444
Georg Brandl7b9c5552007-03-12 14:30:05 +00002445- Bug #1678647: write a newline after printing an exception in any
2446 case, even when converting the value to a string failed.
2447
Georg Brandl871f1bc2007-03-12 13:17:36 +00002448- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002449 its argument, if it exists. If not, it will work like before. This
2450 allows customizing the output of dir() in the presence of a
2451 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002452
Collin Winter276887b2007-03-12 16:11:39 +00002453- Patch #922167: Python no longer segfaults when faced with infinitely
2454 self-recursive reload() calls (as reported by bug #742342).
2455
Georg Brandl3ee81df2008-05-17 18:14:43 +00002456- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002459- Patch #1491866: change the complex() constructor to allow
2460 parthensized forms. This means complex(repr(x)) now works instead of
2461 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002462
Georg Brandlaa2321b2007-03-07 00:40:28 +00002463- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002464 makes the filenames the warning module prints much more sensible
2465 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002466
Georg Brandl49aafc92007-03-07 00:34:46 +00002467- Variant of patch #697613: don't exit the interpreter on a SystemExit
2468 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002469 variable is given, but break into the interactive interpreter just
2470 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002478- Patch #1674228: when assigning a slice (old-style), check for the
2479 sq_ass_slice instead of the sq_slice slot.
2480
Georg Brandl3ee81df2008-05-17 18:14:43 +00002481- When printing an unraisable error, don't print exceptions. before
2482 the name. This duplicates the behavior whening normally printing
2483 exceptions.

2540
Armin Rigo7ccbca92006-10-04 12:17:45 +00002541- A number of places, including integer negation and absolute value,

3111 -- the failure just occurred later, with a more cumbersome
3112 exception.

3325 partial fix for Bug #1574584.
3326
Georg Brandl3ee81df2008-05-17 18:14:43 +00003327- Fix turtle so that time.sleep is imported for the entire library.

3391 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003392
Georg Brandl3ee81df2008-05-17 18:14:43 +00003393- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3394 with RFC 3207 and forgets any knowledge obtained from the server not
3395 obtained from the TLS negotiation itself. Patch contributed by Bill
3396 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003397
Georg Brandl3ee81df2008-05-17 18:14:43 +00003398- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003399 that the SMTP.starttls() caller no longer needs to call ehlo()
3400 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003401 does not claim to support starttls. Adds the
3402 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3403 Fenner.

Georg Brandl56112892008-01-20 13:59:46 +00003440- Patch #1648: added ``sys.getprofile()`` and ``sys.gettrace()``.
3441
Georg Brandl3ee81df2008-05-17 18:14:43 +00003442- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00003446 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003457- itertools.chain() now has an alternate constructor,

3483 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3484 silently miscode subclasses of those types. Now, it raises a
3485 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003486

Georg Brandl3ee81df2008-05-17 18:14:43 +00003501 time so that opening a database previously created with the DB_DUP
3502 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3503 opens. Specifically: dictionary assignment to a DB object will
3504 replace all values for a given key when the database allows
3505 duplicate values. DB users should use DB.put(k, v) when they want
3506 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003507

3513 characters with ASCII value less than 32. Also, it correctly quotes
3514 dots only if they occur on a single line, as opposed to the previous
3515 behavior of quoting dots if they are the second character of any
3516 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003517

3839-----
3840
Georg Brandl3ee81df2008-05-17 18:14:43 +00003841- Unified naming convention for free lists and their limits. All free
3842 lists in Object/ are named ``free_list``, the counter ``numfree``
3843 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3844 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003845
Georg Brandl3ee81df2008-05-17 18:14:43 +00003846- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3847 to ``PyTuple_SetItem``, it can be used to populate a brand new
3848 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003849
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003850- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

3853 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3854 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003855
3856- Patch #1720595: add T_BOOL to the range of structmember types.
3857
3858- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3859 ``PyFloat_GetInfo()`` to the float API.
3860
Georg Brandl3ee81df2008-05-17 18:14:43 +00003861- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3862 of w# format code incorrectly truncated the length to an int, even
3863 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3864 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003865
Georg Brandl3ee81df2008-05-17 18:14:43 +00003866- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3867 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003869- PEP 3123: Provide forward compatibility with Python 3.0, while
3870 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3871 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003872
Georg Brandl3ee81df2008-05-17 18:14:43 +00003873- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3874 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003875
3876- Patch #1733960: Allow T_LONGLONG to accept ints.

3883
3884- Fix some leftovers from the conversion from int to Py_ssize_t
3885 (relevant to strings and sequences of more than 2**31 items).
3886
3887- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3888 outside of pystate.c and should not be necessary.
3889
Georg Brandl3ee81df2008-05-17 18:14:43 +00003890- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3891 absolute imports. In earlier versions they might have used relative
3892 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003893
Georg Brandl3ee81df2008-05-17 18:14:43 +00003894- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3895 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003896
Georg Brandl3ee81df2008-05-17 18:14:43 +00003897- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3898 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003904- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3905 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3906 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3907 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003908

3921
Georg Brandl3ee81df2008-05-17 18:14:43 +00003922- Removed the macfs module. It had been deprecated since Python 2.5.
3923 This lead to the deprecation of macostools.touched() as it relied
3924 solely on macfs and was a no-op under OS X.
