668What's New in Python 2.6.1
669==========================
670
671*Release date: 04-Dec-2008*
672
673Core and Builtins
674-----------------
675
676- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
677 interpreter to abort ("Fatal Python error: Could not reset the stack!")
678 instead of throwing a MemoryError.
679
680- Issue #4367: Python would segfault during compiling when the unicodedata
681 module couldn't be imported and \N escapes were present.
682
683- Issue #4348: Some bytearray methods returned that didn't cause any change to
684 the bytearray, returned the same bytearray instead of a copy.
685
686- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
687
688- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
689
690- Issue #4048: The parser module now correctly validates relative imports.
691
692- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
693 exec statement.
694
695- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
696 method does not return iterators for the 4th and 5th items.
697
698- Issue #4209: Enabling unicode_literals and the print_function in the same
699 __future__ import didn't work.
700
701- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
702 returned a path longer than MAX_PATH. (But It's doubtful this code path is
703 really executed because I cannot move to such directory on win2k)
704
705- Issue #4069: When set.remove(element) is used with a set element, the element
706 is temporarily replaced with an equivalent frozenset. But the eventual
707 KeyError would always report the empty frozenset([]) as the missing key. Now
708 it correctly refers to the initial element.
709
710- Fixed C99 style comments in several files. Python is now C89 compatible
711 again.

859
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000860- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
861 PyString_FromFormat or PyErr_Format to display size_t values. The macro
862 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
863 ``printf`` function, whereas PyString_FromFormat has an independent
864 implementation and uses "%zd" on all platforms for size_t values.
865 This makes a difference on win64, where ``printf`` needs "%Id" to display
866 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +0000868- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

884
Vinay Sajip35e3b032008-09-01 14:33:59 +0000885- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000886 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
887 mechanism. In the process, fix a bug where isinstance() and issubclass(),

983-----------------
984
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000985- Issue #2975: When compiling several extension modules with Visual Studio 2008
986 from the same python interpreter, some environment variables would grow
987 without limit.
988
Benjamin Peterson37346b22008-08-23 20:27:43 +0000989- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
990 exploitation of poor argument checking.
991
Gerhard Häringef2276b2008-09-12 13:54:06 +0000992- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Gerhard Häring6e1afcf2008-09-12 18:58:57 +0000994- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
995 remaining ones have "pysqlite_" prefix.
996
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000997- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00001004- Issue #3781: Add test.test_support.check_warnings() as a convenience
1005 wrapper for warnings.catch_warnings() that makes it easier to check
1006 that expected warning messages are being reported.
1007
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001008- Issue #3796: Some tests functions were not enabled in test_float.

1016
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001017- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001026What's New in Python 2.6 beta 3?
1027================================
1028
Barry Warsaw07a4a382008-08-21 01:15:08 +00001029*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001030
1031Core and Builtins
1032-----------------
1033
Guido van Rossumf8402962008-08-20 15:01:50 +00001034- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1035 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1036 extensions do not automatically benefit from the class attribute
1037 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1038 to their tp_flags field if they care. This is a backwards
1039 compatibility feature; in 3.0, all types will use the cache by
1040 default.
1041
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001042- Keyword arguments can now follow starred arguments. (``f(a, *args,
1043 keyword=23)`` is now valid syntax.)
1044
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001045- ctypes function pointers that are COM methods have a boolean True
1046 value again.
1047
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001048- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1049 by denying s# to parse objects that have a releasebuffer procedure,
1050 and introducing s*.
1051
Georg Brandl1e13ea92008-08-11 09:07:59 +00001052- Issue #3537: Fix an assertion failure when an empty but presized dict
1053 object was stored in the freelist.
1054
Mark Dickinsonb6467572008-08-04 21:30:09 +00001055- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1056 ValueError consistently across platforms.
1057
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001058- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1059 (64bit Unix, for example), unichr() would truncate its argument and return
1060 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1061
Neal Norwitze7d8be82008-07-31 17:17:14 +00001062- Apply security patches from Apple.
1063
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001064- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1065 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1066
Antoine Pitrou92f82162008-07-25 22:22:08 +00001067- Issue #1819: function calls with several named parameters are now on
1068 average 35% faster (as measured by pybench).
1069
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001070- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1071 the python debugger steps into a class statement: the free variables (local
1072 variables defined in an outer scope) would be deleted from the outer scope.
1073
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001074- Issue #2620: Overflow checking when allocating or reallocating memory
1075 was not always being done properly in some python types and extension
1076 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1077 all been updated to perform better checks and places in the code that
1078 would previously leak memory on the error path when such an allocation
1079 failed have been fixed.
1080
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001081Library
1082-------
1083
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001084- Issue #3612: Added some missing basic types in ctypes.wintypes.
1085
Benjamin Petersone977ad42008-08-20 01:42:01 +00001086- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1087 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1088
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001089- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1090 version reported by these tools does not necessarily follow the python
1091 version numbering scheme, so the module is less strict when parsing it.
1092
Nick Coghlanf70385a2008-08-18 12:42:46 +00001093- Issue #2235: Added Py3k warnings for types which will become unhashable
1094 under the stricter __hash__ inheritance rules in 3.0. Several types
1095 which did not meet the rules for hash invariants and were already
1096 unhashable in 3.0 have now been explicitly flagged as unhashable in
1097 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1098 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1099
Brett Cannon88f801d2008-08-18 00:46:22 +00001100- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1101 imported into the module but exposed as part of the module's API.
1102
Brett Cannon7b96f072008-08-18 00:41:11 +00001103- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1104
Brett Cannon46225e72008-08-18 00:36:52 +00001105- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1106
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001107- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1108
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001109- Issue #3575: Incremental decoder's decode function now takes bytearray
1110 by using 's*' instead of 't#'.
1111
Jesus Cea585ad8a2009-07-02 15:37:21 +00001112- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001113 fails unicode conversion on 2nd parameter. (windows only)
1114
Facundo Batista94f243a2008-08-17 03:38:39 +00001115- Issue 2464. urllib2 now supports a malformation in the URL received
1116 in a redirect.
1117
Brett Cannonabe423e2008-08-16 21:47:07 +00001118- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001119 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001120
Facundo Batistaeb90b782008-08-16 14:44:07 +00001121- Issue #2776: fixed small issue when handling an URL with double slash
1122 after a 302 response in the case of not going through a proxy.
1123
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001124- Issue #2676: in the email package, content-type parsing was hanging on
1125 pathological input because of quadratic or exponential behaviour of a
1126 regular expression.
1127
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001128- Issue #3476: binary buffered reading through the new "io" library is now
1129 thread-safe.
1130
Brett Cannonbf3157b2008-08-14 05:00:03 +00001131- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1132 since mimetools itself is deprecated. Because modules are cached, all
1133 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1134
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001135- Issue #3134: shutil referenced undefined WindowsError symbol.
1136
Robert Schuppenies14646332008-08-10 11:01:53 +00001137- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1138 menu entries were not deleted.
1139
Brett Cannon83e81842008-08-09 23:30:55 +00001140- Copied the implementation of reduce() to _functools.reduce() to have a
1141 version that did not raise a DeprecationWarning under -3.
1142
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001143- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1144 a MemoryError rather than silently stop the iteration.
1145
Guido van Rossum59ce9012008-08-09 14:55:34 +00001146- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1147 to _sre.compile() will now be rejected. This should not affect anybody
1148 since the re.compile() function never generates invalid re-bytecode.
1149
Skip Montanaroa032bf42008-08-08 22:52:51 +00001150- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1151 upon first access it can be automatically initialized from the csv file if
1152 it wasn't initialized during instantiation.
1153
Brett Cannon3aa2a492008-08-06 22:28:09 +00001154- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1155 the reload() built-in has been removed.
1156
Brett Cannon7e30b672008-08-04 21:52:25 +00001157- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001158 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1160 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1161 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1162 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1163 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001164
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001165- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1166 raised an AttributeError.
1167
Benjamin Peterson01a24322008-07-28 23:35:27 +00001168- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001169 asking for a specific length. This problem only affected files opened
1170 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001171
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001172- Issue #3449: Update decimal module to use most recent specification
1173 (v. 1.68) and tests (v. 2.58) from IBM.
1174
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001175- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1176
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001177- Issue 1592: Improve error reporting when operations are attempted
1178 on a closed shelf.

1181
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001182- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1183
1184- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1185 invalid arguments.
1186
1187- Issue #3302: Fix several crashes when calling locale's gettext functions
1188 with None arguments.
1189
1190- Issue #3389: Allow resolving dotted names for handlers in logging
1191 configuration files.
1192
1193- Deprecate the sunaudio module for removal in Python 3.0.
1194
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001195- Issue #3394: zipfile.writestr sets external attributes when passed a
1196 file name rather than a ZipInfo instance, so files are extracted with
1197 mode 0600 rather than 000 under Unix.
1198
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001199- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1200 argument in python 2.5, this broke code that subclassed Popen to include its
1201 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1209-------------
1210
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001211- Issue #2235: the C API function PyObject_HashNotImplemented and its
1212 interaction with the tp_hash slot (added in 2.6b2) are now documented
1213
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001214- Issue #643841: The language reference now provides more detailed
1215 coverage of the lookup process for special methods. The disclaimers
1216 regarding lack of coverage of new-style classes have also been
1217 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001220What's New in Python 2.6 beta 2?
1221================================
1222
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001223*Release date: 17-Jul-2008*
1224
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001225Core and Builtins
1226-----------------
1227
Georg Brandl3e483f62008-07-16 22:57:41 +00001228- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1229 its methods now allow for items objects that can be converted to
1230 an integer using operator.index().
1231
Mark Dickinson64b7e502008-07-16 09:40:03 +00001232- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1233 produced a ValueError instead of giving the correct float.
1234
Eric Smitha5fa5a22008-07-16 00:11:49 +00001235- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1236 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1237
Mark Dickinson7103aa42008-07-15 19:08:33 +00001238- Issue #3008: the float type has a new instance method 'float.hex'
1239 and a new class method 'float.fromhex' to convert floating-point
1240 numbers to and from hexadecimal strings, respectively.
1241
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001242- Issue #2235: __hash__ is once again inherited by default. To allow
1243 collections.Hashable to remain meaningful in the presence of the
1244 default hash implementation (object.__hash__), it is now possible
1245 to explicit block inheritance of hash by setting __hash__=None at
1246 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1247 level.
1248
Nick Coghlanb028f502008-07-13 14:52:36 +00001249- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1250 the parent module cannot be found while performing an absolute import.
1251 This means that an incorrectly defined __package__ attribute will
1252 now only prevent relative imports in that module rather than causing
1253 all imports from that module to fail.
1254
Nick Coghlan14ff9942008-07-08 14:21:42 +00001255- Issue #2517: Allow unicode messages in Exceptions again by correctly
1256 bypassing the instance dictionary when looking up __unicode__ on
1257 new-style classes.
1258
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001259- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1260 set to a custom object whose write() method happens to install
1261 another file in sys.stdout.
1262
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001263- Issue #3088: Corrected a race condition in classes derived from
1264 threading.local: the first member set by a thread could be saved in
1265 another thread's dictionary.
1266
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001267- Issue #3004: Minor change to slice.indices(): the start and stop
1268 arguments are now treated identically, making the behaviour easier
1269 to describe and understand. For example, slice(None, -10,
1270 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1271 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00001726 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001727
1728 This is controlled by the configure argument ``--with-universal-archs``:
1729
1730 - ``--with-universal-archs=all``: install 4-way universal
1731
1732 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1733
1734 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1735
1736 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001788- Issue #1631171: Re-implement the 'warnings' module in C (the
1789 original Python code has been kept as backup). This will allow for
1790 using the 'warning's machinery in such places as the parser where
1791 use of pure Python code is not possible. Both the ``showarning()``
1792 and ``formatwarning()`` gain an optional 'line' argument which is
1793 not called by default for backwards-compatibility reasons. Setting
1794 ``warnings.showwarning()`` to an implementation that lacks support
1795 for the ``line`` argument will raise a DeprecationWarning.

1819
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001820- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00001858- Issue #2550: The approach used by client/server code for obtaining
1859 ports to listen on in network-oriented tests has been refined in an
1860 effort to facilitate running multiple instances of the entire
1861 regression test suite in parallel without issue.
1862 test_support.bind_port() has been fixed such that it will always
1863 return a unique port -- which wasn't always the case with the
1864 previous implementation, especially if socket options had been set
1865 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1866 new implementation of bind_port() will actually raise an exception
1867 if it is passed an AF_INET/SOCK_STREAM socket with either the
1868 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1869 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1870 the socket it's been passed. This currently only applies to
1871 Windows. This option prevents any other sockets from binding to the
1872 host/port we've bound to, thus removing the possibility of the
1873 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1874 when a second SOCK_STREAM socket binds and accepts to a host/port
1875 that's already been bound by another socket. The optional preferred
1876 port parameter to bind_port() has been removed. Under no
1877 circumstances should tests be hard coding ports!
1878
1879 test_support.find_unused_port() has also been introduced, which will
1880 pass a temporary socket object to bind_port() in order to obtain an
1881 unused port. The temporary socket object is then closed and
1882 deleted, and the port is returned. This method should only be used
1883 for obtaining an unused port in order to pass to an external program
1884 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1885 a parameter to a server-oriented class that doesn't give you direct
1886 access to the underlying socket used.
1887
1888 Finally, test_support.HOST has been introduced, which should be used
1889 for the host argument of any relevant socket calls (i.e. bind and
1890 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001891
1892 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001893 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001894 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1895 test_asynchat and test_socket_ssl.
1896
Georg Brandl3ee81df2008-05-17 18:14:43 +00001897 It is now possible for multiple instances of the regression test
1898 suite to run in parallel without issue.

2165-----------------
2166
Fred Drakea8ee94b2008-03-01 02:45:07 +00002167- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002168 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002170- Issue #2067: file.__exit__() now calls subclasses' close() method.
2171
2172- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002173
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002174- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002175 issue 215555 for a discussion.
2176
Eric Smitha73fbe72008-02-23 03:09:44 +00002177- Added the future_builtins module, which contains hex() and oct().
2178 These are the PEP 3127 version of these functions, designed to be
2179 compatible with the hex() and oct() builtins from Python 3.0. They
2180 differ slightly in their output formats from the existing, unchanged
2181 Python 2.6 builtins. The expected usage of the future_builtins
2182 module is:
2183 from future_builtins import hex, oct
2184
Eric Smith7ef40bf2008-02-20 23:34:22 +00002185- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2186 exponents for exponents with absolute value < 100. Follows C99
2187 standard. This is a change on Windows, which would use 3 digits.
2188 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2189 so that any alterations it does to the resulting string will be
2190 available in stringlib/formatter.h (for float.__format__).
2191
Eric Smith5a3c1352008-02-19 13:21:56 +00002192- Implemented PEP 3101, Advanced String Formatting. This adds a new
2193 builtin format(); a format() method for str and unicode; a
2194 __format__() method to object, str, unicode, int, long, float, and
2195 datetime; the class string.Formatter; and the C API
2196 PyObject_Format().
2197
Georg Brandl3ee81df2008-05-17 18:14:43 +00002198- Fixed several potential crashes, all caused by specially crafted
2199 __del__ methods exploiting objects in temporarily inconsistent
2200 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002201
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002202- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002203 prevent a possible crash: an Abstract Base Class would try to access
2204 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002205
Georg Brandl3ee81df2008-05-17 18:14:43 +00002206- Fixed repr() and str() of complex numbers with infinity or nan as
2207 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002209- Clear all free lists during a gc.collect() of the highest generation
2210 in order to allow pymalloc to free more arenas. Python may give back
2211 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002212
Georg Brandl3ee81df2008-05-17 18:14:43 +00002213- Issue #2045: Fix an infinite recursion triggered when printing a
2214 subclass of collections.defaultdict, if its default_factory is set
2215 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002216
Christian Heimesf75dbef2008-02-08 00:11:31 +00002217- Fixed a minor memory leak in dictobject.c. The content of the free
2218 list was not freed on interpreter shutdown.
2219
Georg Brandl3ee81df2008-05-17 18:14:43 +00002220- Limit free list of method and builtin function objects to 256
2221 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002222
Georg Brandl3ee81df2008-05-17 18:14:43 +00002223- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2224 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002225 to compact the internal free lists of pre-allocted ints and floats.
2226
Georg Brandl3ee81df2008-05-17 18:14:43 +00002227- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2228 calls. Python expected the return type int but the fork familie
2229 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002230
Georg Brandl3ee81df2008-05-17 18:14:43 +00002231- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2232 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002233
Georg Brandl3ee81df2008-05-17 18:14:43 +00002234- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2235 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002236
Georg Brandl3ee81df2008-05-17 18:14:43 +00002237- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2238 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002240- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2241 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002242
Georg Brandl3ee81df2008-05-17 18:14:43 +00002243- Patch #1473257: generator objects gain a gi_code attribute. This is
2244 the same object as the func_code attribute of the function that
2245 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002246
Georg Brandl3ee81df2008-05-17 18:14:43 +00002247- Issue #1920: "while 0" statements were completely removed by the
2248 compiler, even in the presence of an "else" clause, which is
2249 supposed to be run when the condition is false. Now the compiler
2250 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002251
Guido van Rossumeead05f2008-01-24 18:21:02 +00002252- A few crashers fixed: weakref_in_del.py (issue #1377858);
2253 loosing_dict_ref.py (issue #1303614, test67.py);
2254 borrowed_ref_[34].py (not in tracker).
2255
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002256- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002257 suppressed while an extension is loaded by calling SetErrorMode in
2258 dynload_win.c. The error is still reported properly.
2259
Georg Brandl3ee81df2008-05-17 18:14:43 +00002260- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002261 several extension methods and modules do not work without unicode
2262 support.
2263
Georg Brandl26543b12008-01-21 18:36:51 +00002264- Issue #1882: when compiling code from a string, encoding cookies in the
2265 second line of code were not always recognized correctly.
2266
Georg Brandl14404b62008-01-19 19:27:05 +00002267- Issue #1679: "0x" was taken as a valid integer literal.
2268
Georg Brandl6caad7d2008-01-26 14:19:22 +00002269- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002270 added.
2271
Christian Heimesc94e2b52008-01-14 04:13:37 +00002272- sys.float_info / PyFloat_GetInfo: The floating point information
2273 object was converted from a dict to a specialized structseq object.
2274
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Patch #1816: Added sys.flags structseq. It exposes the status of
2276 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002277
Georg Brandl3ee81df2008-05-17 18:14:43 +00002278- Objects/structseq.c: Implemented new structseq representation. The
2279 patch makes structseqs (e.g. the return value of os.stat) more
2280 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002281
Georg Brandl3ee81df2008-05-17 18:14:43 +00002282- Patch #1700288: added a type attribute cache that caches method
2283 accesses, resulting in speedups in heavily object-oriented code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002294- Improve some exception messages when Windows fails to load an
2295 extension module. Now we get for example '%1 is not a valid Win32
2296 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002303- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002304 and INF. float("nan"), float("inf") and float("-inf") now work on
2305 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002306
Georg Brandl3ee81df2008-05-17 18:14:43 +00002307- Compiler now generates simpler and faster code for dictionary
2308 literals. The oparg for BUILD_MAP now indicates an estimated
2309 dictionary size. There is a new opcode, STORE_MAP, for adding
2310 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002339- Patch #1739468: Directories and zipfiles containing a __main__.py
2340 file can now be directly executed by passing their name to the
2341 interpreter. The directory/zipfile is automatically inserted as the
2342 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002343
Georg Brandl3ee81df2008-05-17 18:14:43 +00002344- Issue #1265: Fix a problem with sys.settrace, if the tracing
2345 function uses a generator expression when at the same time the
2346 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002347
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002348- sets and frozensets now have an isdisjoint() method.

2353
Georg Brandl3ee81df2008-05-17 18:14:43 +00002354- The enumerate() builtin function is no longer bounded to sequences
2355 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2356 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002357
Georg Brandl3ee81df2008-05-17 18:14:43 +00002358- Issue #1686386: Tuple's tp_repr did not take into account the
2359 possibility of having a self-referential tuple, which is possible
2360 from C code. Nor did object's tp_str consider that a type's tp_str
2361 could do something that could lead to an inifinite recursion.
2362 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2363 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002364
Georg Brandl3ee81df2008-05-17 18:14:43 +00002365- Issue #1164: It was possible to trigger deadlock when using the
2366 'print' statement to write to a file since the GIL was not released
2367 as needed. Now PyObject_Print() does the right thing along with
2368 various tp_print implementations of the built-in types and those in
2369 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002370
Georg Brandl3ee81df2008-05-17 18:14:43 +00002371- Issue #1147: Exceptions were directly allowing string exceptions in
2372 their throw() method even though string exceptions no longer
2373 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002374
Georg Brandl3ee81df2008-05-17 18:14:43 +00002375- Issue #1096: Prevent a segfault from getting the repr of a very
2376 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002377
Brett Cannon1e534b52007-09-07 04:18:30 +00002378- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002379 PyObject_Call() never calling back out to Python code to trigger
2380 recursion depth updates/checks. Required the creation of a static
2381 RuntimeError instance in case normalizing an exception put the
2382 recursion check value past its limit. Fixes crashers
2383 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002384

Neal Norwitz0ac60192007-05-27 04:08:54 +00002398- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002399 __*__ attributes. (Some already existed, e.g., __doc__ and
2400 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002401
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002402- Add -3 option to the interpreter to warn about features that are
2403 deprecated and will be changed/removed in Python 3.0.
2404
Georg Brandl2134e752007-05-21 20:34:16 +00002405- Patch #1686487: you can now pass any mapping after '**' in function
2406 calls.
2407
Collin Winter62903052007-05-18 23:11:24 +00002408- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002409 "except E as target:". This is to provide forwards compatibility
2410 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002411
Brett Cannon229cee22007-05-05 01:34:02 +00002412- Deprecate BaseException.message as per PEP 352.
2413
Georg Brandl3ee81df2008-05-17 18:14:43 +00002414- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002415 inherited from a builtin base.
2416
Vinay Sajip8549ce32007-05-06 17:53:37 +00002417- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002418 setting a plain string, ie don't expand to single letter identifiers.
2419
Raymond Hettinger13936692007-04-11 18:40:58 +00002420- Request #1191699: Slices can now be pickled.
2421
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002422- Request #1193128: str.translate() now allows a None argument for
2423 translations that only remove characters without re-mapping the
2424 remaining characters.
2425
Georg Brandl5cb76c12007-03-21 09:00:39 +00002426- Patch #1682205: a TypeError while unpacking an iterable is no longer

2428
Neal Norwitzaa754b72007-03-21 06:39:48 +00002429- Remove unused file Python/fmod.c.
2430
Guido van Rossum143b5642007-03-23 04:58:42 +00002431- Bug #1683368: The object.__init__() and object.__new__() methods are
2432 now stricter in rejecting excess arguments. The only time when
2433 either allows excess arguments is when it is not overridden and the
2434 other one is. For backwards compatibility, when both are
2435 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002436 warning later). Also, type.__init__() insists on the same signature
2437 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002438
Georg Brandl3ee81df2008-05-17 18:14:43 +00002439- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2440 object to complex using its __complex__() method before falling back
2441 to the __float__() method. Therefore, the functions in the cmath
2442 module now can operate on objects that define a __complex__()
2443 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002444
Georg Brandl3ee81df2008-05-17 18:14:43 +00002445- Patch #1623563: allow __class__ assignment for classes with
2446 __slots__. The old and the new class are still required to have the
2447 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002448

2453 ``object.__reduce_ex__()`` is called with an object that is faking
2454 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002455
Georg Brandl3ee81df2008-05-17 18:14:43 +00002456- Patch #1680015: Don't modify __slots__ tuple if it contains an

2460
Georg Brandl7b9c5552007-03-12 14:30:05 +00002461- Bug #1678647: write a newline after printing an exception in any
2462 case, even when converting the value to a string failed.
2463
Georg Brandl871f1bc2007-03-12 13:17:36 +00002464- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002465 its argument, if it exists. If not, it will work like before. This
2466 allows customizing the output of dir() in the presence of a
2467 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002468
Collin Winter276887b2007-03-12 16:11:39 +00002469- Patch #922167: Python no longer segfaults when faced with infinitely
2470 self-recursive reload() calls (as reported by bug #742342).
2471

Georg Brandl3ee81df2008-05-17 18:14:43 +00002475- Patch #1491866: change the complex() constructor to allow
2476 parthensized forms. This means complex(repr(x)) now works instead of
2477 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002478
Georg Brandlaa2321b2007-03-07 00:40:28 +00002479- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002480 makes the filenames the warning module prints much more sensible
2481 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002482
Georg Brandl49aafc92007-03-07 00:34:46 +00002483- Variant of patch #697613: don't exit the interpreter on a SystemExit
2484 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002485 variable is given, but break into the interactive interpreter just
2486 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00002493
Georg Brandl0fca97a2007-03-05 22:28:08 +00002494- Patch #1674228: when assigning a slice (old-style), check for the
2495 sq_ass_slice instead of the sq_slice slot.
2496
Georg Brandl3ee81df2008-05-17 18:14:43 +00002497- When printing an unraisable error, don't print exceptions. before
2498 the name. This duplicates the behavior whening normally printing
2499 exceptions.

2556
Armin Rigo7ccbca92006-10-04 12:17:45 +00002557- A number of places, including integer negation and absolute value,

3127 -- the failure just occurred later, with a more cumbersome
3128 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003409- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3410 with RFC 3207 and forgets any knowledge obtained from the server not
3411 obtained from the TLS negotiation itself. Patch contributed by Bill
3412 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003413
Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003415 that the SMTP.starttls() caller no longer needs to call ehlo()
3416 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003417 does not claim to support starttls. Adds the
3418 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3499 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3500 silently miscode subclasses of those types. Now, it raises a
3501 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003502

Georg Brandl3ee81df2008-05-17 18:14:43 +00003517 time so that opening a database previously created with the DB_DUP
3518 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3519 opens. Specifically: dictionary assignment to a DB object will
3520 replace all values for a given key when the database allows
3521 duplicate values. DB users should use DB.put(k, v) when they want
3522 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003523

3529 characters with ASCII value less than 32. Also, it correctly quotes
3530 dots only if they occur on a single line, as opposed to the previous
3531 behavior of quoting dots if they are the second character of any
3532 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003533

3855-----
3856
Georg Brandl3ee81df2008-05-17 18:14:43 +00003857- Unified naming convention for free lists and their limits. All free
3858 lists in Object/ are named ``free_list``, the counter ``numfree``
3859 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3860 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003861
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3863 to ``PyTuple_SetItem``, it can be used to populate a brand new
3864 frozenset; but it does not steal a reference to the added item.

3876
Georg Brandl3ee81df2008-05-17 18:14:43 +00003877- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3878 of w# format code incorrectly truncated the length to an int, even
3879 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3880 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003881
Georg Brandl3ee81df2008-05-17 18:14:43 +00003882- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3899
3900- Fix some leftovers from the conversion from int to Py_ssize_t
3901 (relevant to strings and sequences of more than 2**31 items).
3902
3903- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3904 outside of pystate.c and should not be necessary.
3905
Georg Brandl3ee81df2008-05-17 18:14:43 +00003906- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3907 absolute imports. In earlier versions they might have used relative
3908 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003909
Georg Brandl3ee81df2008-05-17 18:14:43 +00003910- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3911 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003912
Georg Brandl3ee81df2008-05-17 18:14:43 +00003913- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003920- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3921 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3922 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3923 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003924

3937
Georg Brandl3ee81df2008-05-17 18:14:43 +00003938- Removed the macfs module. It had been deprecated since Python 2.5.
3939 This lead to the deprecation of macostools.touched() as it relied
3940 solely on macfs and was a no-op under OS X.
