30
R. David Murray05afa1a2009-05-05 00:52:14 +000031- Issue #5890: in subclasses of 'property' the __doc__ attribute was

482 302 conformant loader) will now work correctly in most cases (they
483 are still subject to the constraints that exist for all code running

646What's New in Python 2.6.1
647==========================
648
649*Release date: 04-Dec-2008*
650
651Core and Builtins
652-----------------
653
654- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
655 interpreter to abort ("Fatal Python error: Could not reset the stack!")
656 instead of throwing a MemoryError.
657
658- Issue #4367: Python would segfault during compiling when the unicodedata
659 module couldn't be imported and \N escapes were present.
660
661- Issue #4348: Some bytearray methods returned that didn't cause any change to
662 the bytearray, returned the same bytearray instead of a copy.
663
664- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
665
666- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
667
668- Issue #4048: The parser module now correctly validates relative imports.
669
670- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
671 exec statement.
672
673- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
674 method does not return iterators for the 4th and 5th items.
675
676- Issue #4209: Enabling unicode_literals and the print_function in the same
677 __future__ import didn't work.
678
679- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
680 returned a path longer than MAX_PATH. (But It's doubtful this code path is
681 really executed because I cannot move to such directory on win2k)
682
683- Issue #4069: When set.remove(element) is used with a set element, the element
684 is temporarily replaced with an equivalent frozenset. But the eventual
685 KeyError would always report the empty frozenset([]) as the missing key. Now
686 it correctly refers to the initial element.
687
688- Fixed C99 style comments in several files. Python is now C89 compatible
689 again.

704

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000836- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
837
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000838- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
839 PyString_FromFormat or PyErr_Format to display size_t values. The macro
840 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
841 ``printf`` function, whereas PyString_FromFormat has an independent
842 implementation and uses "%zd" on all platforms for size_t values.
843 This makes a difference on win64, where ``printf`` needs "%Id" to display
844 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +0000846- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Vinay Sajip35e3b032008-09-01 14:33:59 +0000860 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000861 was correctly parsed but parsing of subsequent arguments failed.
862
Vinay Sajip35e3b032008-09-01 14:33:59 +0000863- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000864 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
865 mechanism. In the process, fix a bug where isinstance() and issubclass(),
866 when given a tuple of classes as second argument, were looking up
867 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
868 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001004What's New in Python 2.6 beta 3?
1005================================
1006
Barry Warsaw07a4a382008-08-21 01:15:08 +00001007*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001008
1009Core and Builtins
1010-----------------
1011
Guido van Rossumf8402962008-08-20 15:01:50 +00001012- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1013 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1014 extensions do not automatically benefit from the class attribute
1015 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1016 to their tp_flags field if they care. This is a backwards
1017 compatibility feature; in 3.0, all types will use the cache by
1018 default.
1019
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001020- Keyword arguments can now follow starred arguments. (``f(a, *args,
1021 keyword=23)`` is now valid syntax.)
1022
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001023- ctypes function pointers that are COM methods have a boolean True
1024 value again.
1025
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001026- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1027 by denying s# to parse objects that have a releasebuffer procedure,
1028 and introducing s*.
1029
Georg Brandl1e13ea92008-08-11 09:07:59 +00001030- Issue #3537: Fix an assertion failure when an empty but presized dict
1031 object was stored in the freelist.
1032
Mark Dickinsonb6467572008-08-04 21:30:09 +00001033- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1034 ValueError consistently across platforms.
1035
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001036- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1037 (64bit Unix, for example), unichr() would truncate its argument and return
1038 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1039
Neal Norwitze7d8be82008-07-31 17:17:14 +00001040- Apply security patches from Apple.
1041
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001042- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1043 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1044
Antoine Pitrou92f82162008-07-25 22:22:08 +00001045- Issue #1819: function calls with several named parameters are now on
1046 average 35% faster (as measured by pybench).
1047
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001048- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1049 the python debugger steps into a class statement: the free variables (local
1050 variables defined in an outer scope) would be deleted from the outer scope.
1051
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001052- Issue #2620: Overflow checking when allocating or reallocating memory
1053 was not always being done properly in some python types and extension
1054 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1055 all been updated to perform better checks and places in the code that
1056 would previously leak memory on the error path when such an allocation
1057 failed have been fixed.
1058
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001059Library
1060-------
1061
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001062- Issue #3612: Added some missing basic types in ctypes.wintypes.
1063
Benjamin Petersone977ad42008-08-20 01:42:01 +00001064- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1065 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1066
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001067- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1068 version reported by these tools does not necessarily follow the python
1069 version numbering scheme, so the module is less strict when parsing it.
1070
Nick Coghlanf70385a2008-08-18 12:42:46 +00001071- Issue #2235: Added Py3k warnings for types which will become unhashable
1072 under the stricter __hash__ inheritance rules in 3.0. Several types
1073 which did not meet the rules for hash invariants and were already
1074 unhashable in 3.0 have now been explicitly flagged as unhashable in
1075 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1076 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1077
Brett Cannon88f801d2008-08-18 00:46:22 +00001078- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1079 imported into the module but exposed as part of the module's API.
1080
Brett Cannon7b96f072008-08-18 00:41:11 +00001081- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1082
Brett Cannon46225e72008-08-18 00:36:52 +00001083- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1084
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001085- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1086
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001087- Issue #3575: Incremental decoder's decode function now takes bytearray
1088 by using 's*' instead of 't#'.
1089
Jesus Cea585ad8a2009-07-02 15:37:21 +00001090- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001091 fails unicode conversion on 2nd parameter. (windows only)
1092
Facundo Batista94f243a2008-08-17 03:38:39 +00001093- Issue 2464. urllib2 now supports a malformation in the URL received
1094 in a redirect.
1095
Brett Cannonabe423e2008-08-16 21:47:07 +00001096- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001097 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001098
Facundo Batistaeb90b782008-08-16 14:44:07 +00001099- Issue #2776: fixed small issue when handling an URL with double slash
1100 after a 302 response in the case of not going through a proxy.
1101
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001102- Issue #2676: in the email package, content-type parsing was hanging on
1103 pathological input because of quadratic or exponential behaviour of a
1104 regular expression.
1105
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001106- Issue #3476: binary buffered reading through the new "io" library is now
1107 thread-safe.
1108
Brett Cannonbf3157b2008-08-14 05:00:03 +00001109- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1110 since mimetools itself is deprecated. Because modules are cached, all
1111 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1112
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001113- Issue #3134: shutil referenced undefined WindowsError symbol.
1114
Robert Schuppenies14646332008-08-10 11:01:53 +00001115- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1116 menu entries were not deleted.
1117
Brett Cannon83e81842008-08-09 23:30:55 +00001118- Copied the implementation of reduce() to _functools.reduce() to have a
1119 version that did not raise a DeprecationWarning under -3.
1120
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001121- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1122 a MemoryError rather than silently stop the iteration.
1123
Guido van Rossum59ce9012008-08-09 14:55:34 +00001124- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1125 to _sre.compile() will now be rejected. This should not affect anybody
1126 since the re.compile() function never generates invalid re-bytecode.
1127
Skip Montanaroa032bf42008-08-08 22:52:51 +00001128- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1129 upon first access it can be automatically initialized from the csv file if
1130 it wasn't initialized during instantiation.
1131
Brett Cannon3aa2a492008-08-06 22:28:09 +00001132- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1133 the reload() built-in has been removed.
1134
Brett Cannon7e30b672008-08-04 21:52:25 +00001135- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001136 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1139 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1140 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1141 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001142
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001143- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1144 raised an AttributeError.
1145
Benjamin Peterson01a24322008-07-28 23:35:27 +00001146- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001147 asking for a specific length. This problem only affected files opened
1148 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001149
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001150- Issue #3449: Update decimal module to use most recent specification
1151 (v. 1.68) and tests (v. 2.58) from IBM.
1152
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001153- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1154
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001155- Issue 1592: Improve error reporting when operations are attempted
1156 on a closed shelf.
1157

1159
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001160- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1161
1162- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1163 invalid arguments.
1164
1165- Issue #3302: Fix several crashes when calling locale's gettext functions
1166 with None arguments.
1167
1168- Issue #3389: Allow resolving dotted names for handlers in logging
1169 configuration files.
1170
1171- Deprecate the sunaudio module for removal in Python 3.0.
1172
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001173- Issue #3394: zipfile.writestr sets external attributes when passed a
1174 file name rather than a ZipInfo instance, so files are extracted with
1175 mode 0600 rather than 000 under Unix.
1176
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001177- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1178 argument in python 2.5, this broke code that subclassed Popen to include its
1179 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1188
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001189- Issue #2235: the C API function PyObject_HashNotImplemented and its
1190 interaction with the tp_hash slot (added in 2.6b2) are now documented
1191
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001192- Issue #643841: The language reference now provides more detailed
1193 coverage of the lookup process for special methods. The disclaimers
1194 regarding lack of coverage of new-style classes have also been
1195 removed, since the coverage is now fairly reasonable.

1199================================
1200
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001201*Release date: 17-Jul-2008*
1202
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001203Core and Builtins
1204-----------------
1205
Georg Brandl3e483f62008-07-16 22:57:41 +00001206- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1207 its methods now allow for items objects that can be converted to
1208 an integer using operator.index().
1209
Mark Dickinson64b7e502008-07-16 09:40:03 +00001210- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1211 produced a ValueError instead of giving the correct float.
1212
Eric Smitha5fa5a22008-07-16 00:11:49 +00001213- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1214 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1215
Mark Dickinson7103aa42008-07-15 19:08:33 +00001216- Issue #3008: the float type has a new instance method 'float.hex'
1217 and a new class method 'float.fromhex' to convert floating-point
1218 numbers to and from hexadecimal strings, respectively.
1219
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001220- Issue #2235: __hash__ is once again inherited by default. To allow
1221 collections.Hashable to remain meaningful in the presence of the
1222 default hash implementation (object.__hash__), it is now possible
1223 to explicit block inheritance of hash by setting __hash__=None at
1224 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1225 level.
1226
Nick Coghlanb028f502008-07-13 14:52:36 +00001227- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1228 the parent module cannot be found while performing an absolute import.
1229 This means that an incorrectly defined __package__ attribute will
1230 now only prevent relative imports in that module rather than causing
1231 all imports from that module to fail.
1232
Nick Coghlan14ff9942008-07-08 14:21:42 +00001233- Issue #2517: Allow unicode messages in Exceptions again by correctly
1234 bypassing the instance dictionary when looking up __unicode__ on
1235 new-style classes.
1236
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001237- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1238 set to a custom object whose write() method happens to install
1239 another file in sys.stdout.
1240
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001241- Issue #3088: Corrected a race condition in classes derived from

1243 another thread's dictionary.
1244
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001245- Issue #3004: Minor change to slice.indices(): the start and stop
1246 arguments are now treated identically, making the behaviour easier
1247 to describe and understand. For example, slice(None, -10,
1248 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1249 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1250 10, -1).
1251
Georg Brandl278fc502008-07-19 12:46:12 +00001252- Issue #3219: Calling a function with repeated keyword arguments,
1253 f(a=2, a=23), would not cause a syntax error. This was a regression
1254 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00001704 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001705
1706 This is controlled by the configure argument ``--with-universal-archs``:
1707
1708 - ``--with-universal-archs=all``: install 4-way universal
1709
1710 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1711
1712 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1713
1714 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001766- Issue #1631171: Re-implement the 'warnings' module in C (the
1767 original Python code has been kept as backup). This will allow for
1768 using the 'warning's machinery in such places as the parser where
1769 use of pure Python code is not possible. Both the ``showarning()``
1770 and ``formatwarning()`` gain an optional 'line' argument which is
1771 not called by default for backwards-compatibility reasons. Setting
1772 ``warnings.showwarning()`` to an implementation that lacks support
1773 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001798- The getpass module has been improved on Unix. It now uses /dev/tty
1799 by default and uses stderr instead of stdout. A GetPassWarning is

1826 Modules/_ctypes/libffi/configure.ac.
1827
Georg Brandl3ee81df2008-05-17 18:14:43 +00001828- Issue #2385: distutils.core.run_script() makes __file__ available,
1829 so the controlled environment will more closely mirror the typical
1830 script environment. This supports setup.py scripts that refer to
1831 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001836- Issue #2550: The approach used by client/server code for obtaining
1837 ports to listen on in network-oriented tests has been refined in an
1838 effort to facilitate running multiple instances of the entire
1839 regression test suite in parallel without issue.
1840 test_support.bind_port() has been fixed such that it will always
1841 return a unique port -- which wasn't always the case with the
1842 previous implementation, especially if socket options had been set
1843 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1844 new implementation of bind_port() will actually raise an exception
1845 if it is passed an AF_INET/SOCK_STREAM socket with either the
1846 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1847 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1848 the socket it's been passed. This currently only applies to
1849 Windows. This option prevents any other sockets from binding to the
1850 host/port we've bound to, thus removing the possibility of the
1851 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1852 when a second SOCK_STREAM socket binds and accepts to a host/port
1853 that's already been bound by another socket. The optional preferred
1854 port parameter to bind_port() has been removed. Under no
1855 circumstances should tests be hard coding ports!
1856
1857 test_support.find_unused_port() has also been introduced, which will
1858 pass a temporary socket object to bind_port() in order to obtain an
1859 unused port. The temporary socket object is then closed and
1860 deleted, and the port is returned. This method should only be used
1861 for obtaining an unused port in order to pass to an external program
1862 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1863 a parameter to a server-oriented class that doesn't give you direct
1864 access to the underlying socket used.
1865
1866 Finally, test_support.HOST has been introduced, which should be used
1867 for the host argument of any relevant socket calls (i.e. bind and
1868 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001869
1870 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001871 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001872 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1873 test_asynchat and test_socket_ssl.
1874
Georg Brandl3ee81df2008-05-17 18:14:43 +00001875 It is now possible for multiple instances of the regression test
1876 suite to run in parallel without issue.

2142Core and builtins
2143-----------------
2144
Fred Drakea8ee94b2008-03-01 02:45:07 +00002145- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002146 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002147
Georg Brandlad61bc82008-02-23 15:11:18 +00002148- Issue #2067: file.__exit__() now calls subclasses' close() method.
2149
2150- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002151
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002152- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002153 issue 215555 for a discussion.
2154
Eric Smitha73fbe72008-02-23 03:09:44 +00002155- Added the future_builtins module, which contains hex() and oct().
2156 These are the PEP 3127 version of these functions, designed to be
2157 compatible with the hex() and oct() builtins from Python 3.0. They
2158 differ slightly in their output formats from the existing, unchanged
2159 Python 2.6 builtins. The expected usage of the future_builtins
2160 module is:
2161 from future_builtins import hex, oct
2162
Eric Smith7ef40bf2008-02-20 23:34:22 +00002163- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2164 exponents for exponents with absolute value < 100. Follows C99
2165 standard. This is a change on Windows, which would use 3 digits.
2166 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2167 so that any alterations it does to the resulting string will be
2168 available in stringlib/formatter.h (for float.__format__).
2169
Eric Smith5a3c1352008-02-19 13:21:56 +00002170- Implemented PEP 3101, Advanced String Formatting. This adds a new
2171 builtin format(); a format() method for str and unicode; a
2172 __format__() method to object, str, unicode, int, long, float, and
2173 datetime; the class string.Formatter; and the C API
2174 PyObject_Format().
2175
Georg Brandl3ee81df2008-05-17 18:14:43 +00002176- Fixed several potential crashes, all caused by specially crafted
2177 __del__ methods exploiting objects in temporarily inconsistent
2178 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002179
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002180- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002181 prevent a possible crash: an Abstract Base Class would try to access
2182 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002183
Georg Brandl3ee81df2008-05-17 18:14:43 +00002184- Fixed repr() and str() of complex numbers with infinity or nan as
2185 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002186
Georg Brandl3ee81df2008-05-17 18:14:43 +00002187- Clear all free lists during a gc.collect() of the highest generation
2188 in order to allow pymalloc to free more arenas. Python may give back
2189 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002190
Georg Brandl3ee81df2008-05-17 18:14:43 +00002191- Issue #2045: Fix an infinite recursion triggered when printing a
2192 subclass of collections.defaultdict, if its default_factory is set
2193 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002194
Christian Heimesf75dbef2008-02-08 00:11:31 +00002195- Fixed a minor memory leak in dictobject.c. The content of the free
2196 list was not freed on interpreter shutdown.
2197
Georg Brandl3ee81df2008-05-17 18:14:43 +00002198- Limit free list of method and builtin function objects to 256
2199 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002200
Georg Brandl3ee81df2008-05-17 18:14:43 +00002201- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2202 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002203 to compact the internal free lists of pre-allocted ints and floats.
2204
Georg Brandl3ee81df2008-05-17 18:14:43 +00002205- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2206 calls. Python expected the return type int but the fork familie
2207 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002208
Georg Brandl3ee81df2008-05-17 18:14:43 +00002209- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2210 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002211
Georg Brandl3ee81df2008-05-17 18:14:43 +00002212- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2213 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2219 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002220
Georg Brandl3ee81df2008-05-17 18:14:43 +00002221- Patch #1473257: generator objects gain a gi_code attribute. This is
2222 the same object as the func_code attribute of the function that
2223 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002224
Georg Brandl3ee81df2008-05-17 18:14:43 +00002225- Issue #1920: "while 0" statements were completely removed by the
2226 compiler, even in the presence of an "else" clause, which is
2227 supposed to be run when the condition is false. Now the compiler
2228 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002229
Guido van Rossumeead05f2008-01-24 18:21:02 +00002230- A few crashers fixed: weakref_in_del.py (issue #1377858);
2231 loosing_dict_ref.py (issue #1303614, test67.py);
2232 borrowed_ref_[34].py (not in tracker).
2233
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002234- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002235 suppressed while an extension is loaded by calling SetErrorMode in
2236 dynload_win.c. The error is still reported properly.
2237
Georg Brandl3ee81df2008-05-17 18:14:43 +00002238- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002239 several extension methods and modules do not work without unicode
2240 support.
2241
Georg Brandl26543b12008-01-21 18:36:51 +00002242- Issue #1882: when compiling code from a string, encoding cookies in the
2243 second line of code were not always recognized correctly.
2244
Georg Brandl14404b62008-01-19 19:27:05 +00002245- Issue #1679: "0x" was taken as a valid integer literal.
2246
Georg Brandl6caad7d2008-01-26 14:19:22 +00002247- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002248 added.
2249
Christian Heimesc94e2b52008-01-14 04:13:37 +00002250- sys.float_info / PyFloat_GetInfo: The floating point information
2251 object was converted from a dict to a specialized structseq object.
2252
Georg Brandl3ee81df2008-05-17 18:14:43 +00002253- Patch #1816: Added sys.flags structseq. It exposes the status of
2254 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002255
Georg Brandl3ee81df2008-05-17 18:14:43 +00002256- Objects/structseq.c: Implemented new structseq representation. The
2257 patch makes structseqs (e.g. the return value of os.stat) more
2258 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002259
Georg Brandl3ee81df2008-05-17 18:14:43 +00002260- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002282 and INF. float("nan"), float("inf") and float("-inf") now work on
2283 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002284
Georg Brandl3ee81df2008-05-17 18:14:43 +00002285- Compiler now generates simpler and faster code for dictionary
2286 literals. The oparg for BUILD_MAP now indicates an estimated
2287 dictionary size. There is a new opcode, STORE_MAP, for adding
2288 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002332- The enumerate() builtin function is no longer bounded to sequences
2333 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2334 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002335
Georg Brandl3ee81df2008-05-17 18:14:43 +00002336- Issue #1686386: Tuple's tp_repr did not take into account the
2337 possibility of having a self-referential tuple, which is possible
2338 from C code. Nor did object's tp_str consider that a type's tp_str
2339 could do something that could lead to an inifinite recursion.
2340 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2341 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002342
Georg Brandl3ee81df2008-05-17 18:14:43 +00002343- Issue #1164: It was possible to trigger deadlock when using the
2344 'print' statement to write to a file since the GIL was not released
2345 as needed. Now PyObject_Print() does the right thing along with
2346 various tp_print implementations of the built-in types and those in
2347 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002348
Georg Brandl3ee81df2008-05-17 18:14:43 +00002349- Issue #1147: Exceptions were directly allowing string exceptions in
2350 their throw() method even though string exceptions no longer
2351 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002352
Georg Brandl3ee81df2008-05-17 18:14:43 +00002353- Issue #1096: Prevent a segfault from getting the repr of a very
2354 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002355
Brett Cannon1e534b52007-09-07 04:18:30 +00002356- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002357 PyObject_Call() never calling back out to Python code to trigger
2358 recursion depth updates/checks. Required the creation of a static
2359 RuntimeError instance in case normalizing an exception put the
2360 recursion check value past its limit. Fixes crashers
2361 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002362

Neal Norwitz0ac60192007-05-27 04:08:54 +00002376- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002377 __*__ attributes. (Some already existed, e.g., __doc__ and
2378 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002379
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002380- Add -3 option to the interpreter to warn about features that are
2381 deprecated and will be changed/removed in Python 3.0.
2382
Georg Brandl2134e752007-05-21 20:34:16 +00002383- Patch #1686487: you can now pass any mapping after '**' in function
2384 calls.
2385
Collin Winter62903052007-05-18 23:11:24 +00002386- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002387 "except E as target:". This is to provide forwards compatibility
2388 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002389
Brett Cannon229cee22007-05-05 01:34:02 +00002390- Deprecate BaseException.message as per PEP 352.
2391
Georg Brandl3ee81df2008-05-17 18:14:43 +00002392- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002393 inherited from a builtin base.
2394
Vinay Sajip8549ce32007-05-06 17:53:37 +00002395- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002396 setting a plain string, ie don't expand to single letter identifiers.
2397
Raymond Hettinger13936692007-04-11 18:40:58 +00002398- Request #1191699: Slices can now be pickled.
2399
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002400- Request #1193128: str.translate() now allows a None argument for
2401 translations that only remove characters without re-mapping the
2402 remaining characters.
2403
Georg Brandl5cb76c12007-03-21 09:00:39 +00002404- Patch #1682205: a TypeError while unpacking an iterable is no longer
2405 masked by a generic one with the message "unpack non-sequence".
2406
Neal Norwitzaa754b72007-03-21 06:39:48 +00002407- Remove unused file Python/fmod.c.
2408
Guido van Rossum143b5642007-03-23 04:58:42 +00002409- Bug #1683368: The object.__init__() and object.__new__() methods are
2410 now stricter in rejecting excess arguments. The only time when
2411 either allows excess arguments is when it is not overridden and the
2412 other one is. For backwards compatibility, when both are
2413 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002414 warning later). Also, type.__init__() insists on the same signature
2415 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002416
Georg Brandl3ee81df2008-05-17 18:14:43 +00002417- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2418 object to complex using its __complex__() method before falling back
2419 to the __float__() method. Therefore, the functions in the cmath
2420 module now can operate on objects that define a __complex__()
2421 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002422
Georg Brandl3ee81df2008-05-17 18:14:43 +00002423- Patch #1623563: allow __class__ assignment for classes with
2424 __slots__. The old and the new class are still required to have the
2425 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002426

2431 ``object.__reduce_ex__()`` is called with an object that is faking
2432 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002433
Georg Brandl3ee81df2008-05-17 18:14:43 +00002434- Patch #1680015: Don't modify __slots__ tuple if it contains an

2438
Georg Brandl7b9c5552007-03-12 14:30:05 +00002439- Bug #1678647: write a newline after printing an exception in any
2440 case, even when converting the value to a string failed.
2441
Georg Brandl871f1bc2007-03-12 13:17:36 +00002442- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002443 its argument, if it exists. If not, it will work like before. This
2444 allows customizing the output of dir() in the presence of a
2445 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002446
Collin Winter276887b2007-03-12 16:11:39 +00002447- Patch #922167: Python no longer segfaults when faced with infinitely
2448 self-recursive reload() calls (as reported by bug #742342).

2454 parthensized forms. This means complex(repr(x)) now works instead of
2455 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002456
Georg Brandlaa2321b2007-03-07 00:40:28 +00002457- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002458 makes the filenames the warning module prints much more sensible
2459 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002460

2462 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002463 variable is given, but break into the interactive interpreter just
2464 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002472- Patch #1674228: when assigning a slice (old-style), check for the
2473 sq_ass_slice instead of the sq_slice slot.
2474
Georg Brandl3ee81df2008-05-17 18:14:43 +00002475- When printing an unraisable error, don't print exceptions. before
2476 the name. This duplicates the behavior whening normally printing
2477 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002578 generator expressions (x for x, in ... ) works again. Fixing this

2580 .pyc files generated before 2.5c2 will be regenerated.

3319 partial fix for Bug #1574584.
3320
Georg Brandl3ee81df2008-05-17 18:14:43 +00003321- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3388 with RFC 3207 and forgets any knowledge obtained from the server not
3389 obtained from the TLS negotiation itself. Patch contributed by Bill
3390 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003391
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003393 that the SMTP.starttls() caller no longer needs to call ehlo()
3394 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003395 does not claim to support starttls. Adds the
3396 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3477 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3478 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003495 time so that opening a database previously created with the DB_DUP
3496 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3497 opens. Specifically: dictionary assignment to a DB object will
3498 replace all values for a given key when the database allows
3499 duplicate values. DB users should use DB.put(k, v) when they want
3500 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003501

3507 characters with ASCII value less than 32. Also, it correctly quotes
3508 dots only if they occur on a single line, as opposed to the previous
3509 behavior of quoting dots if they are the second character of any
3510 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003511

3833-----
3834
Georg Brandl3ee81df2008-05-17 18:14:43 +00003835- Unified naming convention for free lists and their limits. All free
3836 lists in Object/ are named ``free_list``, the counter ``numfree``
3837 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3838 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003839
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3841 to ``PyTuple_SetItem``, it can be used to populate a brand new
3842 frozenset; but it does not steal a reference to the added item.

3851
3852- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3853 ``PyFloat_GetInfo()`` to the float API.
3854
Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3856 of w# format code incorrectly truncated the length to an int, even
3857 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3858 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003859
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3878- Fix some leftovers from the conversion from int to Py_ssize_t
3879 (relevant to strings and sequences of more than 2**31 items).
3880
3881- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3882 outside of pystate.c and should not be necessary.
3883
Georg Brandl3ee81df2008-05-17 18:14:43 +00003884- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3885 absolute imports. In earlier versions they might have used relative
3886 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003887
Georg Brandl3ee81df2008-05-17 18:14:43 +00003888- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3889 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003890
Georg Brandl3ee81df2008-05-17 18:14:43 +00003891- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003898- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3899 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3900 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3901 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003902

Georg Brandl3ee81df2008-05-17 18:14:43 +00003916- Removed the macfs module. It had been deprecated since Python 2.5.
3917 This lead to the deprecation of macostools.touched() as it relied
3918 solely on macfs and was a no-op under OS X.
