664What's New in Python 2.6.1
665==========================
666
667*Release date: 04-Dec-2008*
668
669Core and Builtins
670-----------------
671
672- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
673 interpreter to abort ("Fatal Python error: Could not reset the stack!")
674 instead of throwing a MemoryError.
675
676- Issue #4367: Python would segfault during compiling when the unicodedata
677 module couldn't be imported and \N escapes were present.
678
679- Issue #4348: Some bytearray methods returned that didn't cause any change to
680 the bytearray, returned the same bytearray instead of a copy.
681
682- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
683
684- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
685
686- Issue #4048: The parser module now correctly validates relative imports.
687
688- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

692 method does not return iterators for the 4th and 5th items.
693
694- Issue #4209: Enabling unicode_literals and the print_function in the same
695 __future__ import didn't work.
696
697- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
698 returned a path longer than MAX_PATH. (But It's doubtful this code path is
699 really executed because I cannot move to such directory on win2k)
700
701- Issue #4069: When set.remove(element) is used with a set element, the element
702 is temporarily replaced with an equivalent frozenset. But the eventual
703 KeyError would always report the empty frozenset([]) as the missing key. Now
704 it correctly refers to the initial element.
705
706- Fixed C99 style comments in several files. Python is now C89 compatible
707 again.

855
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000856- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
857 PyString_FromFormat or PyErr_Format to display size_t values. The macro
858 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
859 ``printf`` function, whereas PyString_FromFormat has an independent
860 implementation and uses "%zd" on all platforms for size_t values.
861 This makes a difference on win64, where ``printf`` needs "%Id" to display
862 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000882 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
883 mechanism. In the process, fix a bug where isinstance() and issubclass(),

979-----------------
980
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000981- Issue #2975: When compiling several extension modules with Visual Studio 2008
982 from the same python interpreter, some environment variables would grow
983 without limit.
984
Benjamin Peterson37346b22008-08-23 20:27:43 +0000985- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
986 exploitation of poor argument checking.
987
Gerhard Häringef2276b2008-09-12 13:54:06 +0000988- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Gerhard Häring6e1afcf2008-09-12 18:58:57 +0000990- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
991 remaining ones have "pysqlite_" prefix.
992
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000993- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00001000- Issue #3781: Add test.test_support.check_warnings() as a convenience
1001 wrapper for warnings.catch_warnings() that makes it easier to check
1002 that expected warning messages are being reported.
1003
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001004- Issue #3796: Some tests functions were not enabled in test_float.

1012
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001013- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001022What's New in Python 2.6 beta 3?
1023================================
1024
Barry Warsaw07a4a382008-08-21 01:15:08 +00001025*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001026
1027Core and Builtins
1028-----------------
1029
Guido van Rossumf8402962008-08-20 15:01:50 +00001030- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1031 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1032 extensions do not automatically benefit from the class attribute
1033 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1034 to their tp_flags field if they care. This is a backwards
1035 compatibility feature; in 3.0, all types will use the cache by
1036 default.
1037
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001038- Keyword arguments can now follow starred arguments. (``f(a, *args,
1039 keyword=23)`` is now valid syntax.)
1040
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001041- ctypes function pointers that are COM methods have a boolean True
1042 value again.
1043
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001044- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1045 by denying s# to parse objects that have a releasebuffer procedure,
1046 and introducing s*.
1047
Georg Brandl1e13ea92008-08-11 09:07:59 +00001048- Issue #3537: Fix an assertion failure when an empty but presized dict
1049 object was stored in the freelist.
1050
Mark Dickinsonb6467572008-08-04 21:30:09 +00001051- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1052 ValueError consistently across platforms.
1053
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001054- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1055 (64bit Unix, for example), unichr() would truncate its argument and return
1056 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1057
Neal Norwitze7d8be82008-07-31 17:17:14 +00001058- Apply security patches from Apple.
1059
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001060- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1061 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1062
Antoine Pitrou92f82162008-07-25 22:22:08 +00001063- Issue #1819: function calls with several named parameters are now on
1064 average 35% faster (as measured by pybench).
1065
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001066- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1067 the python debugger steps into a class statement: the free variables (local
1068 variables defined in an outer scope) would be deleted from the outer scope.
1069
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001070- Issue #2620: Overflow checking when allocating or reallocating memory
1071 was not always being done properly in some python types and extension
1072 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1073 all been updated to perform better checks and places in the code that
1074 would previously leak memory on the error path when such an allocation
1075 failed have been fixed.
1076
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001077Library
1078-------
1079
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001080- Issue #3612: Added some missing basic types in ctypes.wintypes.
1081
Benjamin Petersone977ad42008-08-20 01:42:01 +00001082- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1083 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1084
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001085- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1086 version reported by these tools does not necessarily follow the python
1087 version numbering scheme, so the module is less strict when parsing it.
1088
Nick Coghlanf70385a2008-08-18 12:42:46 +00001089- Issue #2235: Added Py3k warnings for types which will become unhashable
1090 under the stricter __hash__ inheritance rules in 3.0. Several types
1091 which did not meet the rules for hash invariants and were already
1092 unhashable in 3.0 have now been explicitly flagged as unhashable in
1093 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1094 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1095
Brett Cannon88f801d2008-08-18 00:46:22 +00001096- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1097 imported into the module but exposed as part of the module's API.
1098
Brett Cannon7b96f072008-08-18 00:41:11 +00001099- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1100
Brett Cannon46225e72008-08-18 00:36:52 +00001101- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1102
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001103- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1104
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001105- Issue #3575: Incremental decoder's decode function now takes bytearray
1106 by using 's*' instead of 't#'.
1107
Jesus Cea585ad8a2009-07-02 15:37:21 +00001108- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001109 fails unicode conversion on 2nd parameter. (windows only)
1110
Facundo Batista94f243a2008-08-17 03:38:39 +00001111- Issue 2464. urllib2 now supports a malformation in the URL received
1112 in a redirect.
1113
Brett Cannonabe423e2008-08-16 21:47:07 +00001114- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001115 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001116
Facundo Batistaeb90b782008-08-16 14:44:07 +00001117- Issue #2776: fixed small issue when handling an URL with double slash
1118 after a 302 response in the case of not going through a proxy.
1119
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001120- Issue #2676: in the email package, content-type parsing was hanging on
1121 pathological input because of quadratic or exponential behaviour of a
1122 regular expression.
1123
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001124- Issue #3476: binary buffered reading through the new "io" library is now
1125 thread-safe.
1126
Brett Cannonbf3157b2008-08-14 05:00:03 +00001127- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1128 since mimetools itself is deprecated. Because modules are cached, all
1129 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1130
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001131- Issue #3134: shutil referenced undefined WindowsError symbol.
1132
Robert Schuppenies14646332008-08-10 11:01:53 +00001133- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1134 menu entries were not deleted.
1135
Brett Cannon83e81842008-08-09 23:30:55 +00001136- Copied the implementation of reduce() to _functools.reduce() to have a
1137 version that did not raise a DeprecationWarning under -3.
1138
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001139- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1140 a MemoryError rather than silently stop the iteration.
1141
Guido van Rossum59ce9012008-08-09 14:55:34 +00001142- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1143 to _sre.compile() will now be rejected. This should not affect anybody
1144 since the re.compile() function never generates invalid re-bytecode.
1145
Skip Montanaroa032bf42008-08-08 22:52:51 +00001146- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1147 upon first access it can be automatically initialized from the csv file if
1148 it wasn't initialized during instantiation.
1149
Brett Cannon3aa2a492008-08-06 22:28:09 +00001150- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1151 the reload() built-in has been removed.
1152
Brett Cannon7e30b672008-08-04 21:52:25 +00001153- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001154 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1157 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1158 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1159 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001160
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001161- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1162 raised an AttributeError.
1163
Benjamin Peterson01a24322008-07-28 23:35:27 +00001164- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001165 asking for a specific length. This problem only affected files opened
1166 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001167
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001168- Issue #3449: Update decimal module to use most recent specification
1169 (v. 1.68) and tests (v. 2.58) from IBM.
1170
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001171- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1172
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001173- Issue 1592: Improve error reporting when operations are attempted
1174 on a closed shelf.

1177
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001178- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1179
1180- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1181 invalid arguments.
1182
1183- Issue #3302: Fix several crashes when calling locale's gettext functions
1184 with None arguments.
1185
1186- Issue #3389: Allow resolving dotted names for handlers in logging
1187 configuration files.
1188
1189- Deprecate the sunaudio module for removal in Python 3.0.
1190
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001191- Issue #3394: zipfile.writestr sets external attributes when passed a
1192 file name rather than a ZipInfo instance, so files are extracted with
1193 mode 0600 rather than 000 under Unix.
1194
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001195- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1196 argument in python 2.5, this broke code that subclassed Popen to include its
1197 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1205-------------
1206
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001207- Issue #2235: the C API function PyObject_HashNotImplemented and its
1208 interaction with the tp_hash slot (added in 2.6b2) are now documented
1209
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001210- Issue #643841: The language reference now provides more detailed
1211 coverage of the lookup process for special methods. The disclaimers
1212 regarding lack of coverage of new-style classes have also been
1213 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001216What's New in Python 2.6 beta 2?
1217================================
1218
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001219*Release date: 17-Jul-2008*
1220
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001221Core and Builtins
1222-----------------
1223
Georg Brandl3e483f62008-07-16 22:57:41 +00001224- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1225 its methods now allow for items objects that can be converted to
1226 an integer using operator.index().
1227
Mark Dickinson64b7e502008-07-16 09:40:03 +00001228- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1229 produced a ValueError instead of giving the correct float.
1230
Eric Smitha5fa5a22008-07-16 00:11:49 +00001231- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1232 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1233
Mark Dickinson7103aa42008-07-15 19:08:33 +00001234- Issue #3008: the float type has a new instance method 'float.hex'
1235 and a new class method 'float.fromhex' to convert floating-point
1236 numbers to and from hexadecimal strings, respectively.
1237
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001238- Issue #2235: __hash__ is once again inherited by default. To allow
1239 collections.Hashable to remain meaningful in the presence of the
1240 default hash implementation (object.__hash__), it is now possible
1241 to explicit block inheritance of hash by setting __hash__=None at
1242 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1243 level.
1244
Nick Coghlanb028f502008-07-13 14:52:36 +00001245- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1246 the parent module cannot be found while performing an absolute import.
1247 This means that an incorrectly defined __package__ attribute will
1248 now only prevent relative imports in that module rather than causing
1249 all imports from that module to fail.
1250
Nick Coghlan14ff9942008-07-08 14:21:42 +00001251- Issue #2517: Allow unicode messages in Exceptions again by correctly
1252 bypassing the instance dictionary when looking up __unicode__ on
1253 new-style classes.
1254
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001255- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1256 set to a custom object whose write() method happens to install
1257 another file in sys.stdout.
1258
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001259- Issue #3088: Corrected a race condition in classes derived from
1260 threading.local: the first member set by a thread could be saved in
1261 another thread's dictionary.
1262
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001263- Issue #3004: Minor change to slice.indices(): the start and stop
1264 arguments are now treated identically, making the behaviour easier
1265 to describe and understand. For example, slice(None, -10,
1266 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1267 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1268 10, -1).
1269
Georg Brandl278fc502008-07-19 12:46:12 +00001270- Issue #3219: Calling a function with repeated keyword arguments,
1271 f(a=2, a=23), would not cause a syntax error. This was a regression

Georg Brandl5cc774e2008-06-11 20:28:06 +00001722 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001723
1724 This is controlled by the configure argument ``--with-universal-archs``:
1725
1726 - ``--with-universal-archs=all``: install 4-way universal
1727
1728 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1729
1730 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1731

Georg Brandl3ee81df2008-05-17 18:14:43 +00001784- Issue #1631171: Re-implement the 'warnings' module in C (the
1785 original Python code has been kept as backup). This will allow for
1786 using the 'warning's machinery in such places as the parser where
1787 use of pure Python code is not possible. Both the ``showarning()``
1788 and ``formatwarning()`` gain an optional 'line' argument which is
1789 not called by default for backwards-compatibility reasons. Setting
1790 ``warnings.showwarning()`` to an implementation that lacks support
1791 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001816- The getpass module has been improved on Unix. It now uses /dev/tty
1817 by default and uses stderr instead of stdout. A GetPassWarning is

Georg Brandl3ee81df2008-05-17 18:14:43 +00001854- Issue #2550: The approach used by client/server code for obtaining
1855 ports to listen on in network-oriented tests has been refined in an
1856 effort to facilitate running multiple instances of the entire
1857 regression test suite in parallel without issue.
1858 test_support.bind_port() has been fixed such that it will always
1859 return a unique port -- which wasn't always the case with the
1860 previous implementation, especially if socket options had been set
1861 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1862 new implementation of bind_port() will actually raise an exception
1863 if it is passed an AF_INET/SOCK_STREAM socket with either the
1864 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1865 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1866 the socket it's been passed. This currently only applies to
1867 Windows. This option prevents any other sockets from binding to the
1868 host/port we've bound to, thus removing the possibility of the
1869 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1870 when a second SOCK_STREAM socket binds and accepts to a host/port
1871 that's already been bound by another socket. The optional preferred
1872 port parameter to bind_port() has been removed. Under no
1873 circumstances should tests be hard coding ports!
1874
1875 test_support.find_unused_port() has also been introduced, which will
1876 pass a temporary socket object to bind_port() in order to obtain an
1877 unused port. The temporary socket object is then closed and
1878 deleted, and the port is returned. This method should only be used
1879 for obtaining an unused port in order to pass to an external program
1880 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1881 a parameter to a server-oriented class that doesn't give you direct
1882 access to the underlying socket used.
1883
1884 Finally, test_support.HOST has been introduced, which should be used
1885 for the host argument of any relevant socket calls (i.e. bind and
1886 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001887
1888 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001889 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001890 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1891 test_asynchat and test_socket_ssl.
1892
Georg Brandl3ee81df2008-05-17 18:14:43 +00001893 It is now possible for multiple instances of the regression test
1894 suite to run in parallel without issue.

2161-----------------
2162
Fred Drakea8ee94b2008-03-01 02:45:07 +00002163- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002164 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002166- Issue #2067: file.__exit__() now calls subclasses' close() method.
2167
2168- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002169
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002170- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002171 issue 215555 for a discussion.
2172
Eric Smitha73fbe72008-02-23 03:09:44 +00002173- Added the future_builtins module, which contains hex() and oct().
2174 These are the PEP 3127 version of these functions, designed to be
2175 compatible with the hex() and oct() builtins from Python 3.0. They
2176 differ slightly in their output formats from the existing, unchanged
2177 Python 2.6 builtins. The expected usage of the future_builtins
2178 module is:
2179 from future_builtins import hex, oct
2180
Eric Smith7ef40bf2008-02-20 23:34:22 +00002181- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2182 exponents for exponents with absolute value < 100. Follows C99
2183 standard. This is a change on Windows, which would use 3 digits.
2184 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2185 so that any alterations it does to the resulting string will be
2186 available in stringlib/formatter.h (for float.__format__).
2187
Eric Smith5a3c1352008-02-19 13:21:56 +00002188- Implemented PEP 3101, Advanced String Formatting. This adds a new
2189 builtin format(); a format() method for str and unicode; a
2190 __format__() method to object, str, unicode, int, long, float, and
2191 datetime; the class string.Formatter; and the C API
2192 PyObject_Format().
2193
Georg Brandl3ee81df2008-05-17 18:14:43 +00002194- Fixed several potential crashes, all caused by specially crafted
2195 __del__ methods exploiting objects in temporarily inconsistent
2196 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002197
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002198- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002199 prevent a possible crash: an Abstract Base Class would try to access
2200 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002201
Georg Brandl3ee81df2008-05-17 18:14:43 +00002202- Fixed repr() and str() of complex numbers with infinity or nan as
2203 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002204
Georg Brandl3ee81df2008-05-17 18:14:43 +00002205- Clear all free lists during a gc.collect() of the highest generation
2206 in order to allow pymalloc to free more arenas. Python may give back
2207 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002208
Georg Brandl3ee81df2008-05-17 18:14:43 +00002209- Issue #2045: Fix an infinite recursion triggered when printing a
2210 subclass of collections.defaultdict, if its default_factory is set
2211 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002212
Christian Heimesf75dbef2008-02-08 00:11:31 +00002213- Fixed a minor memory leak in dictobject.c. The content of the free
2214 list was not freed on interpreter shutdown.
2215
Georg Brandl3ee81df2008-05-17 18:14:43 +00002216- Limit free list of method and builtin function objects to 256
2217 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002218
Georg Brandl3ee81df2008-05-17 18:14:43 +00002219- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2220 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002221 to compact the internal free lists of pre-allocted ints and floats.
2222
Georg Brandl3ee81df2008-05-17 18:14:43 +00002223- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2224 calls. Python expected the return type int but the fork familie
2225 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002226
Georg Brandl3ee81df2008-05-17 18:14:43 +00002227- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2228 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002229
Georg Brandl3ee81df2008-05-17 18:14:43 +00002230- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2231 with the collections.Sequence API.

2237 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002238
Georg Brandl3ee81df2008-05-17 18:14:43 +00002239- Patch #1473257: generator objects gain a gi_code attribute. This is
2240 the same object as the func_code attribute of the function that
2241 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002242
Georg Brandl3ee81df2008-05-17 18:14:43 +00002243- Issue #1920: "while 0" statements were completely removed by the
2244 compiler, even in the presence of an "else" clause, which is
2245 supposed to be run when the condition is false. Now the compiler
2246 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002247
Guido van Rossumeead05f2008-01-24 18:21:02 +00002248- A few crashers fixed: weakref_in_del.py (issue #1377858);
2249 loosing_dict_ref.py (issue #1303614, test67.py);
2250 borrowed_ref_[34].py (not in tracker).
2251
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002252- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002253 suppressed while an extension is loaded by calling SetErrorMode in
2254 dynload_win.c. The error is still reported properly.
2255
Georg Brandl3ee81df2008-05-17 18:14:43 +00002256- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002257 several extension methods and modules do not work without unicode
2258 support.
2259
Georg Brandl26543b12008-01-21 18:36:51 +00002260- Issue #1882: when compiling code from a string, encoding cookies in the
2261 second line of code were not always recognized correctly.
2262
Georg Brandl14404b62008-01-19 19:27:05 +00002263- Issue #1679: "0x" was taken as a valid integer literal.
2264
Georg Brandl6caad7d2008-01-26 14:19:22 +00002265- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002266 added.
2267
Christian Heimesc94e2b52008-01-14 04:13:37 +00002268- sys.float_info / PyFloat_GetInfo: The floating point information
2269 object was converted from a dict to a specialized structseq object.
2270
Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Patch #1816: Added sys.flags structseq. It exposes the status of
2272 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002273
Georg Brandl3ee81df2008-05-17 18:14:43 +00002274- Objects/structseq.c: Implemented new structseq representation. The

2276 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002277
Georg Brandl3ee81df2008-05-17 18:14:43 +00002278- Patch #1700288: added a type attribute cache that caches method

2304 literals. The oparg for BUILD_MAP now indicates an estimated
2305 dictionary size. There is a new opcode, STORE_MAP, for adding
2306 entries to the dictionary.

Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002334
Georg Brandl3ee81df2008-05-17 18:14:43 +00002335- Patch #1739468: Directories and zipfiles containing a __main__.py
2336 file can now be directly executed by passing their name to the
2337 interpreter. The directory/zipfile is automatically inserted as the
2338 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002340- Issue #1265: Fix a problem with sys.settrace, if the tracing
2341 function uses a generator expression when at the same time the
2342 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002343
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002344- sets and frozensets now have an isdisjoint() method.
2345

2347
Neal Norwitz44f326e2007-10-05 05:29:17 +00002348- Fix warnings found by the new version of the Coverity checker.
2349
Georg Brandl3ee81df2008-05-17 18:14:43 +00002350- The enumerate() builtin function is no longer bounded to sequences
2351 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2352 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002353
Georg Brandl3ee81df2008-05-17 18:14:43 +00002354- Issue #1686386: Tuple's tp_repr did not take into account the
2355 possibility of having a self-referential tuple, which is possible
2356 from C code. Nor did object's tp_str consider that a type's tp_str
2357 could do something that could lead to an inifinite recursion.
2358 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2359 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002360
Georg Brandl3ee81df2008-05-17 18:14:43 +00002361- Issue #1164: It was possible to trigger deadlock when using the
2362 'print' statement to write to a file since the GIL was not released
2363 as needed. Now PyObject_Print() does the right thing along with
2364 various tp_print implementations of the built-in types and those in
2365 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002366
Georg Brandl3ee81df2008-05-17 18:14:43 +00002367- Issue #1147: Exceptions were directly allowing string exceptions in
2368 their throw() method even though string exceptions no longer
2369 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002370
Georg Brandl3ee81df2008-05-17 18:14:43 +00002371- Issue #1096: Prevent a segfault from getting the repr of a very
2372 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002373
Brett Cannon1e534b52007-09-07 04:18:30 +00002374- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002375 PyObject_Call() never calling back out to Python code to trigger
2376 recursion depth updates/checks. Required the creation of a static
2377 RuntimeError instance in case normalizing an exception put the
2378 recursion check value past its limit. Fixes crashers
2379 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002380

Neal Norwitz0ac60192007-05-27 04:08:54 +00002394- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002395 __*__ attributes. (Some already existed, e.g., __doc__ and
2396 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002397
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002398- Add -3 option to the interpreter to warn about features that are
2399 deprecated and will be changed/removed in Python 3.0.
2400
Georg Brandl2134e752007-05-21 20:34:16 +00002401- Patch #1686487: you can now pass any mapping after '**' in function
2402 calls.
2403
Collin Winter62903052007-05-18 23:11:24 +00002404- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002405 "except E as target:". This is to provide forwards compatibility
2406 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002407
Brett Cannon229cee22007-05-05 01:34:02 +00002408- Deprecate BaseException.message as per PEP 352.
2409
Georg Brandl3ee81df2008-05-17 18:14:43 +00002410- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002411 inherited from a builtin base.
2412
Vinay Sajip8549ce32007-05-06 17:53:37 +00002413- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002414 setting a plain string, ie don't expand to single letter identifiers.
2415
Raymond Hettinger13936692007-04-11 18:40:58 +00002416- Request #1191699: Slices can now be pickled.
2417
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002418- Request #1193128: str.translate() now allows a None argument for
2419 translations that only remove characters without re-mapping the
2420 remaining characters.
2421
Georg Brandl5cb76c12007-03-21 09:00:39 +00002422- Patch #1682205: a TypeError while unpacking an iterable is no longer
2423 masked by a generic one with the message "unpack non-sequence".
2424
Neal Norwitzaa754b72007-03-21 06:39:48 +00002425- Remove unused file Python/fmod.c.
2426
Guido van Rossum143b5642007-03-23 04:58:42 +00002427- Bug #1683368: The object.__init__() and object.__new__() methods are
2428 now stricter in rejecting excess arguments. The only time when
2429 either allows excess arguments is when it is not overridden and the
2430 other one is. For backwards compatibility, when both are
2431 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002432 warning later). Also, type.__init__() insists on the same signature
2433 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002434
Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2436 object to complex using its __complex__() method before falling back
2437 to the __float__() method. Therefore, the functions in the cmath
2438 module now can operate on objects that define a __complex__()
2439 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002440
Georg Brandl3ee81df2008-05-17 18:14:43 +00002441- Patch #1623563: allow __class__ assignment for classes with
2442 __slots__. The old and the new class are still required to have the
2443 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002444

2449 ``object.__reduce_ex__()`` is called with an object that is faking
2450 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002451
Georg Brandl3ee81df2008-05-17 18:14:43 +00002452- Patch #1680015: Don't modify __slots__ tuple if it contains an

2456
Georg Brandl7b9c5552007-03-12 14:30:05 +00002457- Bug #1678647: write a newline after printing an exception in any
2458 case, even when converting the value to a string failed.
2459
Georg Brandl871f1bc2007-03-12 13:17:36 +00002460- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002461 its argument, if it exists. If not, it will work like before. This
2462 allows customizing the output of dir() in the presence of a
2463 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002464
Collin Winter276887b2007-03-12 16:11:39 +00002465- Patch #922167: Python no longer segfaults when faced with infinitely
2466 self-recursive reload() calls (as reported by bug #742342).
2467

Georg Brandl3ee81df2008-05-17 18:14:43 +00002471- Patch #1491866: change the complex() constructor to allow
2472 parthensized forms. This means complex(repr(x)) now works instead of
2473 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002474
Georg Brandlaa2321b2007-03-07 00:40:28 +00002475- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002476 makes the filenames the warning module prints much more sensible
2477 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002478

2480 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002481 variable is given, but break into the interactive interpreter just
2482 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002490- Patch #1674228: when assigning a slice (old-style), check for the
2491 sq_ass_slice instead of the sq_slice slot.
2492
Georg Brandl3ee81df2008-05-17 18:14:43 +00002493- When printing an unraisable error, don't print exceptions. before
2494 the name. This duplicates the behavior whening normally printing
2495 exceptions.

2552
Armin Rigo7ccbca92006-10-04 12:17:45 +00002553- A number of places, including integer negation and absolute value,

3123 -- the failure just occurred later, with a more cumbersome
3124 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003405- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3406 with RFC 3207 and forgets any knowledge obtained from the server not
3407 obtained from the TLS negotiation itself. Patch contributed by Bill
3408 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003409
Georg Brandl3ee81df2008-05-17 18:14:43 +00003410- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003411 that the SMTP.starttls() caller no longer needs to call ehlo()
3412 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003413 does not claim to support starttls. Adds the
3414 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3495 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3496 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00003498

Georg Brandl3ee81df2008-05-17 18:14:43 +00003513 time so that opening a database previously created with the DB_DUP
3514 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3515 opens. Specifically: dictionary assignment to a DB object will
3516 replace all values for a given key when the database allows
3517 duplicate values. DB users should use DB.put(k, v) when they want
3518 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003519

3525 characters with ASCII value less than 32. Also, it correctly quotes
3526 dots only if they occur on a single line, as opposed to the previous
3527 behavior of quoting dots if they are the second character of any
3528 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003529

3851-----
3852
Georg Brandl3ee81df2008-05-17 18:14:43 +00003853- Unified naming convention for free lists and their limits. All free
3854 lists in Object/ are named ``free_list``, the counter ``numfree``
3855 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3856 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003857
Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3859 to ``PyTuple_SetItem``, it can be used to populate a brand new
3860 frozenset; but it does not steal a reference to the added item.

3872
Georg Brandl3ee81df2008-05-17 18:14:43 +00003873- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3874 of w# format code incorrectly truncated the length to an int, even
3875 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3876 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003877
Georg Brandl3ee81df2008-05-17 18:14:43 +00003878- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3896- Fix some leftovers from the conversion from int to Py_ssize_t
3897 (relevant to strings and sequences of more than 2**31 items).
3898
3899- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3900 outside of pystate.c and should not be necessary.
3901
Georg Brandl3ee81df2008-05-17 18:14:43 +00003902- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3903 absolute imports. In earlier versions they might have used relative
3904 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003905
Georg Brandl3ee81df2008-05-17 18:14:43 +00003906- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3907 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003908
Georg Brandl3ee81df2008-05-17 18:14:43 +00003909- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003934- Removed the macfs module. It had been deprecated since Python 2.5.
3935 This lead to the deprecation of macostools.touched() as it relied
