441
Vinay Sajip6badbe92009-01-20 22:49:13 +0000442- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000443 method on file objects with closefd=False. The file descriptor is still

446
Georg Brandlfa71a902008-12-05 09:08:28 +0000447- Issue #3689: The list reversed iterator now supports __length_hint__

814What's New in Python 2.6.1
815==========================
816
817*Release date: 04-Dec-2008*
818
819Core and Builtins
820-----------------
821
822- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
823 interpreter to abort ("Fatal Python error: Could not reset the stack!")
824 instead of throwing a MemoryError.
825
826- Issue #4367: Python would segfault during compiling when the unicodedata
827 module couldn't be imported and \N escapes were present.
828
829- Issue #4348: Some bytearray methods returned that didn't cause any change to
830 the bytearray, returned the same bytearray instead of a copy.
831
832- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
833
834- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
835
836- Issue #4048: The parser module now correctly validates relative imports.
837
838- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

843
844- Issue #4209: Enabling unicode_literals and the print_function in the same
845 __future__ import didn't work.
846
847- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
848 returned a path longer than MAX_PATH. (But It's doubtful this code path is
849 really executed because I cannot move to such directory on win2k)
850
851- Issue #4069: When set.remove(element) is used with a set element, the element
852 is temporarily replaced with an equivalent frozenset. But the eventual
853 KeyError would always report the empty frozenset([]) as the missing key. Now
854 it correctly refers to the initial element.
855
856- Fixed C99 style comments in several files. Python is now C89 compatible
857 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001004- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1005
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001006- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1007 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1008 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1009 ``printf`` function, whereas PyString_FromFormat has an independent
1010 implementation and uses "%zd" on all platforms for size_t values.
1011 This makes a difference on win64, where ``printf`` needs "%Id" to display
1012 64bit values.
1013
Benjamin Peterson97179b02008-09-09 20:55:01 +00001014- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1015 error.
1016
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001017- Issue #3777: long() applied to a float object now always return a long
1018 object; previously an int would be returned for small values. the __long__
1019 method is allowed to return either an int or a long, but the behaviour of
1020 float objects should not change to respect backward compatibility.
1021
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001022- Issue #3751: str.rpartition would perform a left-partition when called with
1023 a unicode argument.
1024
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001025- Issue #3683: Fix compilation when --without-threads is given.
1026
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001027- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001028 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001029 was correctly parsed but parsing of subsequent arguments failed.
1030
Vinay Sajip35e3b032008-09-01 14:33:59 +00001031- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001032 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1033 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1034 when given a tuple of classes as second argument, were looking up
1035 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1036 type object.
1037
Neal Norwitz18aa3882008-08-24 05:04:52 +00001038- Fix crashes on memory allocation failure found with failmalloc.
1039
1040- Fix memory leaks found with valgrind and update suppressions file.
1041
1042- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1043
1044- Fix problem using wrong name in decimal module reported by pychecker.
1045
Christian Heimes7d4c3172008-08-22 19:47:25 +00001046- Silenced another compiler warning about a used but not defined
1047 function 'stringlib_contains_obj'.
1048
Benjamin Peterson712ee922008-08-24 18:10:20 +00001049- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1050 ``__delslice__``.
1051
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001052- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1053 library targets in the Makefile.
1054
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001055- Issue #1204: The configure script now tests for additional libraries
1056 that may be required when linking against readline. This fixes issues
1057 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00001067- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
1068 stack usage in the case of deeply nested objects.
1069
Guido van Rossume3c4fd92008-09-10 14:27:00 +00001070- Issue #3629: Fix sre "bytecode" validator for an end case.

1073
Nick Coghland2e09382008-09-11 12:11:06 +00001074- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1075 silent misbehaviour when a single instance is nested in multiple
1076 with statements, or when the methods are invoked in the wrong order.
1077
Vinay Sajip844f7412008-09-09 13:42:08 +00001078- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1079
Nick Coghland2e09382008-09-11 12:11:06 +00001080- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001081 return a list or None rather than a custom object.
1082
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001083- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00001106- Issue 3602: Moved test.test_support.catch_warning() to
1107 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1108 for catch_warnings() also led to an improvement in the raising of a
1109 DeprecationWarning related to warnings.warn_explicit().
1110
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001111- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001131- Issue #2975: When compiling several extension modules with Visual Studio 2008
1132 from the same python interpreter, some environment variables would grow
1133 without limit.
1134
Benjamin Peterson37346b22008-08-23 20:27:43 +00001135- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001172What's New in Python 2.6 beta 3?
1173================================
1174
Barry Warsaw07a4a382008-08-21 01:15:08 +00001175*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001176
1177Core and Builtins
1178-----------------
1179
Guido van Rossumf8402962008-08-20 15:01:50 +00001180- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1181 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1182 extensions do not automatically benefit from the class attribute
1183 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1184 to their tp_flags field if they care. This is a backwards
1185 compatibility feature; in 3.0, all types will use the cache by
1186 default.
1187
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001188- Keyword arguments can now follow starred arguments. (``f(a, *args,
1189 keyword=23)`` is now valid syntax.)
1190
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001191- ctypes function pointers that are COM methods have a boolean True
1192 value again.
1193
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001194- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1195 by denying s# to parse objects that have a releasebuffer procedure,
1196 and introducing s*.
1197
Georg Brandl1e13ea92008-08-11 09:07:59 +00001198- Issue #3537: Fix an assertion failure when an empty but presized dict
1199 object was stored in the freelist.
1200
Mark Dickinsonb6467572008-08-04 21:30:09 +00001201- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1202 ValueError consistently across platforms.
1203
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001204- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1205 (64bit Unix, for example), unichr() would truncate its argument and return
1206 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1207
Neal Norwitze7d8be82008-07-31 17:17:14 +00001208- Apply security patches from Apple.
1209
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001210- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1211 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1212
Antoine Pitrou92f82162008-07-25 22:22:08 +00001213- Issue #1819: function calls with several named parameters are now on
1214 average 35% faster (as measured by pybench).
1215
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001216- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1217 the python debugger steps into a class statement: the free variables (local
1218 variables defined in an outer scope) would be deleted from the outer scope.
1219
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001220- Issue #2620: Overflow checking when allocating or reallocating memory
1221 was not always being done properly in some python types and extension
1222 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1223 all been updated to perform better checks and places in the code that
1224 would previously leak memory on the error path when such an allocation
1225 failed have been fixed.

1229
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001230- Issue #3612: Added some missing basic types in ctypes.wintypes.
1231
Benjamin Petersone977ad42008-08-20 01:42:01 +00001232- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1233 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1234
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001235- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1236 version reported by these tools does not necessarily follow the python
1237 version numbering scheme, so the module is less strict when parsing it.
1238
Nick Coghlanf70385a2008-08-18 12:42:46 +00001239- Issue #2235: Added Py3k warnings for types which will become unhashable
1240 under the stricter __hash__ inheritance rules in 3.0. Several types
1241 which did not meet the rules for hash invariants and were already
1242 unhashable in 3.0 have now been explicitly flagged as unhashable in
1243 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1244 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1245
Brett Cannon88f801d2008-08-18 00:46:22 +00001246- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1247 imported into the module but exposed as part of the module's API.
1248
Brett Cannon7b96f072008-08-18 00:41:11 +00001249- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1250
Brett Cannon46225e72008-08-18 00:36:52 +00001251- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001253- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1254
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001255- Issue #3575: Incremental decoder's decode function now takes bytearray
1256 by using 's*' instead of 't#'.
1257
Jesus Cea585ad8a2009-07-02 15:37:21 +00001258- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001259 fails unicode conversion on 2nd parameter. (windows only)
1260
Facundo Batista94f243a2008-08-17 03:38:39 +00001261- Issue 2464. urllib2 now supports a malformation in the URL received
1262 in a redirect.
1263
Brett Cannonabe423e2008-08-16 21:47:07 +00001264- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001265 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001266
Facundo Batistaeb90b782008-08-16 14:44:07 +00001267- Issue #2776: fixed small issue when handling an URL with double slash
1268 after a 302 response in the case of not going through a proxy.
1269
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001270- Issue #2676: in the email package, content-type parsing was hanging on
1271 pathological input because of quadratic or exponential behaviour of a
1272 regular expression.
1273
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001274- Issue #3476: binary buffered reading through the new "io" library is now
1275 thread-safe.
1276
Brett Cannonbf3157b2008-08-14 05:00:03 +00001277- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1278 since mimetools itself is deprecated. Because modules are cached, all
1279 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1280
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001281- Issue #3134: shutil referenced undefined WindowsError symbol.
1282
Robert Schuppenies14646332008-08-10 11:01:53 +00001283- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1284 menu entries were not deleted.
1285
Brett Cannon83e81842008-08-09 23:30:55 +00001286- Copied the implementation of reduce() to _functools.reduce() to have a
1287 version that did not raise a DeprecationWarning under -3.
1288
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001289- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1290 a MemoryError rather than silently stop the iteration.
1291

1293 to _sre.compile() will now be rejected. This should not affect anybody

Antoine Pitroude781a42008-08-09 12:43:23 +00001315 asking for a specific length. This problem only affected files opened

1372-----------------
1373
Georg Brandl3e483f62008-07-16 22:57:41 +00001374- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1375 its methods now allow for items objects that can be converted to
1376 an integer using operator.index().
1377
Mark Dickinson64b7e502008-07-16 09:40:03 +00001378- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1379 produced a ValueError instead of giving the correct float.
1380
Eric Smitha5fa5a22008-07-16 00:11:49 +00001381- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1382 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1383
Mark Dickinson7103aa42008-07-15 19:08:33 +00001384- Issue #3008: the float type has a new instance method 'float.hex'
1385 and a new class method 'float.fromhex' to convert floating-point
1386 numbers to and from hexadecimal strings, respectively.
1387
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001388- Issue #2235: __hash__ is once again inherited by default. To allow
1389 collections.Hashable to remain meaningful in the presence of the
1390 default hash implementation (object.__hash__), it is now possible
1391 to explicit block inheritance of hash by setting __hash__=None at
1392 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1393 level.
1394
Nick Coghlanb028f502008-07-13 14:52:36 +00001395- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1396 the parent module cannot be found while performing an absolute import.
1397 This means that an incorrectly defined __package__ attribute will
1398 now only prevent relative imports in that module rather than causing
1399 all imports from that module to fail.
1400
Nick Coghlan14ff9942008-07-08 14:21:42 +00001401- Issue #2517: Allow unicode messages in Exceptions again by correctly

1411 another thread's dictionary.
1412
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001413- Issue #3004: Minor change to slice.indices(): the start and stop
1414 arguments are now treated identically, making the behaviour easier
1415 to describe and understand. For example, slice(None, -10,
1416 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1417 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1418 10, -1).
1419
Georg Brandl278fc502008-07-19 12:46:12 +00001420- Issue #3219: Calling a function with repeated keyword arguments,
1421 f(a=2, a=23), would not cause a syntax error. This was a regression
1422 from 2.4 caused by the switch to the new compiler.

1433 error when they failed.
1434
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001435- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001460- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1461 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001462 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001463 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001479- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1867
Brett Cannonb61d8012008-05-11 23:39:04 +00001868- ``Lib/lib-old`` is now added to sys.path.
1869
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001870- On MacOS X it is now possible to install the framework in 64-bit
1871 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001872 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001873
1874 This is controlled by the configure argument ``--with-universal-archs``:
1875
1876 - ``--with-universal-archs=all``: install 4-way universal
1877
1878 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1879
1880 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1881
1882 This option should be used in combination with ``--enable-universalsdk=``.
1883
1884 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00001893
1894- The PyString functions have been renamed to PyBytes. A batch of
1895 defines were added so that the linker still sees the original
1896 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001934- Issue #1631171: Re-implement the 'warnings' module in C (the
1935 original Python code has been kept as backup). This will allow for
1936 using the 'warning's machinery in such places as the parser where
1937 use of pure Python code is not possible. Both the ``showarning()``
1938 and ``formatwarning()`` gain an optional 'line' argument which is
1939 not called by default for backwards-compatibility reasons. Setting
1940 ``warnings.showwarning()`` to an implementation that lacks support
1941 for the ``line`` argument will raise a DeprecationWarning.

1965
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001966- The getpass module has been improved on Unix. It now uses /dev/tty
1967 by default and uses stderr instead of stdout. A GetPassWarning is
1968 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001983- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001984 extension modules between 32 and 64 bit platforms. See the distutls

1997 so the controlled environment will more closely mirror the typical
1998 script environment. This supports setup.py scripts that refer to
1999 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002004- Issue #2550: The approach used by client/server code for obtaining
2005 ports to listen on in network-oriented tests has been refined in an
2006 effort to facilitate running multiple instances of the entire
2007 regression test suite in parallel without issue.
2008 test_support.bind_port() has been fixed such that it will always
2009 return a unique port -- which wasn't always the case with the
2010 previous implementation, especially if socket options had been set
2011 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2012 new implementation of bind_port() will actually raise an exception
2013 if it is passed an AF_INET/SOCK_STREAM socket with either the
2014 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2015 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2016 the socket it's been passed. This currently only applies to
2017 Windows. This option prevents any other sockets from binding to the
2018 host/port we've bound to, thus removing the possibility of the
2019 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2020 when a second SOCK_STREAM socket binds and accepts to a host/port
2021 that's already been bound by another socket. The optional preferred
2022 port parameter to bind_port() has been removed. Under no
2023 circumstances should tests be hard coding ports!
2024
2025 test_support.find_unused_port() has also been introduced, which will
2026 pass a temporary socket object to bind_port() in order to obtain an
2027 unused port. The temporary socket object is then closed and
2028 deleted, and the port is returned. This method should only be used
2029 for obtaining an unused port in order to pass to an external program
2030 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2031 a parameter to a server-oriented class that doesn't give you direct
2032 access to the underlying socket used.
2033
2034 Finally, test_support.HOST has been introduced, which should be used
2035 for the host argument of any relevant socket calls (i.e. bind and
2036 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002037
2038 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002039 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002040 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2041 test_asynchat and test_socket_ssl.
2042
Georg Brandl3ee81df2008-05-17 18:14:43 +00002043 It is now possible for multiple instances of the regression test
2044 suite to run in parallel without issue.

2311-----------------
2312
Fred Drakea8ee94b2008-03-01 02:45:07 +00002313- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002314 644. The mode is now inherited from the py file.

2317
2318- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002319
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002320- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002321 issue 215555 for a discussion.
2322
Eric Smitha73fbe72008-02-23 03:09:44 +00002323- Added the future_builtins module, which contains hex() and oct().
2324 These are the PEP 3127 version of these functions, designed to be
2325 compatible with the hex() and oct() builtins from Python 3.0. They
2326 differ slightly in their output formats from the existing, unchanged
2327 Python 2.6 builtins. The expected usage of the future_builtins
2328 module is:
2329 from future_builtins import hex, oct
2330
Eric Smith7ef40bf2008-02-20 23:34:22 +00002331- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2332 exponents for exponents with absolute value < 100. Follows C99
2333 standard. This is a change on Windows, which would use 3 digits.
2334 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2335 so that any alterations it does to the resulting string will be
2336 available in stringlib/formatter.h (for float.__format__).
2337
Eric Smith5a3c1352008-02-19 13:21:56 +00002338- Implemented PEP 3101, Advanced String Formatting. This adds a new
2339 builtin format(); a format() method for str and unicode; a
2340 __format__() method to object, str, unicode, int, long, float, and
2341 datetime; the class string.Formatter; and the C API
2342 PyObject_Format().
2343
Georg Brandl3ee81df2008-05-17 18:14:43 +00002344- Fixed several potential crashes, all caused by specially crafted
2345 __del__ methods exploiting objects in temporarily inconsistent
2346 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002347
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002348- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002349 prevent a possible crash: an Abstract Base Class would try to access
2350 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002355- Clear all free lists during a gc.collect() of the highest generation
2356 in order to allow pymalloc to free more arenas. Python may give back
2357 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002358
Georg Brandl3ee81df2008-05-17 18:14:43 +00002359- Issue #2045: Fix an infinite recursion triggered when printing a
2360 subclass of collections.defaultdict, if its default_factory is set
2361 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002362
Christian Heimesf75dbef2008-02-08 00:11:31 +00002363- Fixed a minor memory leak in dictobject.c. The content of the free
2364 list was not freed on interpreter shutdown.
2365
Georg Brandl3ee81df2008-05-17 18:14:43 +00002366- Limit free list of method and builtin function objects to 256
2367 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002368
Georg Brandl3ee81df2008-05-17 18:14:43 +00002369- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2370 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002371 to compact the internal free lists of pre-allocted ints and floats.
2372
Georg Brandl3ee81df2008-05-17 18:14:43 +00002373- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2374 calls. Python expected the return type int but the fork familie
2375 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002376
Georg Brandl3ee81df2008-05-17 18:14:43 +00002377- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002380- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2381 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002382
Georg Brandl3ee81df2008-05-17 18:14:43 +00002383- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2384 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002385
Georg Brandl3ee81df2008-05-17 18:14:43 +00002386- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2387 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002388
Georg Brandl3ee81df2008-05-17 18:14:43 +00002389- Patch #1473257: generator objects gain a gi_code attribute. This is
2390 the same object as the func_code attribute of the function that
2391 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002392
Georg Brandl3ee81df2008-05-17 18:14:43 +00002393- Issue #1920: "while 0" statements were completely removed by the
2394 compiler, even in the presence of an "else" clause, which is
2395 supposed to be run when the condition is false. Now the compiler
2396 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002397
Guido van Rossumeead05f2008-01-24 18:21:02 +00002398- A few crashers fixed: weakref_in_del.py (issue #1377858);
2399 loosing_dict_ref.py (issue #1303614, test67.py);
2400 borrowed_ref_[34].py (not in tracker).
2401
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002402- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002403 suppressed while an extension is loaded by calling SetErrorMode in
2404 dynload_win.c. The error is still reported properly.
2405
Georg Brandl3ee81df2008-05-17 18:14:43 +00002406- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002407 several extension methods and modules do not work without unicode
2408 support.
2409
Georg Brandl26543b12008-01-21 18:36:51 +00002410- Issue #1882: when compiling code from a string, encoding cookies in the
2411 second line of code were not always recognized correctly.
2412
Georg Brandl14404b62008-01-19 19:27:05 +00002413- Issue #1679: "0x" was taken as a valid integer literal.
2414
Georg Brandl6caad7d2008-01-26 14:19:22 +00002415- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002416 added.
2417
Christian Heimesc94e2b52008-01-14 04:13:37 +00002418- sys.float_info / PyFloat_GetInfo: The floating point information
2419 object was converted from a dict to a specialized structseq object.
2420
Georg Brandl3ee81df2008-05-17 18:14:43 +00002421- Patch #1816: Added sys.flags structseq. It exposes the status of
2422 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002423
Georg Brandl3ee81df2008-05-17 18:14:43 +00002424- Objects/structseq.c: Implemented new structseq representation. The
2425 patch makes structseqs (e.g. the return value of os.stat) more
2426 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002427
Georg Brandl3ee81df2008-05-17 18:14:43 +00002428- Patch #1700288: added a type attribute cache that caches method
2429 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002430
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002431- Bug #1776: __import__() no longer accepts filenames on any platform.
2432 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002433
Georg Brandlaed6c662008-01-07 17:25:53 +00002434- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2435
Georg Brandl3ee81df2008-05-17 18:14:43 +00002436- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2437 envvar and sys.dont_write_bytecode attribute. All these can be set
2438 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002439
Georg Brandl3ee81df2008-05-17 18:14:43 +00002440- Improve some exception messages when Windows fails to load an
2441 extension module. Now we get for example '%1 is not a valid Win32
2442 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002443

2447 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002448
Christian Heimes0a8143f2007-12-18 23:22:54 +00002449- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002450 and INF. float("nan"), float("inf") and float("-inf") now work on
2451 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002452
Georg Brandl3ee81df2008-05-17 18:14:43 +00002453- Compiler now generates simpler and faster code for dictionary
2454 literals. The oparg for BUILD_MAP now indicates an estimated
2455 dictionary size. There is a new opcode, STORE_MAP, for adding
2456 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002485- Patch #1739468: Directories and zipfiles containing a __main__.py
2486 file can now be directly executed by passing their name to the
2487 interpreter. The directory/zipfile is automatically inserted as the
2488 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002489
Georg Brandl3ee81df2008-05-17 18:14:43 +00002490- Issue #1265: Fix a problem with sys.settrace, if the tracing
2491 function uses a generator expression when at the same time the
2492 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002493
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002494- sets and frozensets now have an isdisjoint() method.
2495

2497
Neal Norwitz44f326e2007-10-05 05:29:17 +00002498- Fix warnings found by the new version of the Coverity checker.
2499
Georg Brandl3ee81df2008-05-17 18:14:43 +00002500- The enumerate() builtin function is no longer bounded to sequences
2501 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2502 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002503
Georg Brandl3ee81df2008-05-17 18:14:43 +00002504- Issue #1686386: Tuple's tp_repr did not take into account the
2505 possibility of having a self-referential tuple, which is possible
2506 from C code. Nor did object's tp_str consider that a type's tp_str
2507 could do something that could lead to an inifinite recursion.
2508 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2509 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002510
Georg Brandl3ee81df2008-05-17 18:14:43 +00002511- Issue #1164: It was possible to trigger deadlock when using the
2512 'print' statement to write to a file since the GIL was not released
2513 as needed. Now PyObject_Print() does the right thing along with
2514 various tp_print implementations of the built-in types and those in
2515 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002516
Georg Brandl3ee81df2008-05-17 18:14:43 +00002517- Issue #1147: Exceptions were directly allowing string exceptions in
2518 their throw() method even though string exceptions no longer
2519 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002520
Georg Brandl3ee81df2008-05-17 18:14:43 +00002521- Issue #1096: Prevent a segfault from getting the repr of a very
2522 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002523
Brett Cannon1e534b52007-09-07 04:18:30 +00002524- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002525 PyObject_Call() never calling back out to Python code to trigger
2526 recursion depth updates/checks. Required the creation of a static
2527 RuntimeError instance in case normalizing an exception put the
2528 recursion check value past its limit. Fixes crashers
2529 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002530
Georg Brandl3ee81df2008-05-17 18:14:43 +00002531- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002544- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002545 __*__ attributes. (Some already existed, e.g., __doc__ and
2546 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002547
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002548- Add -3 option to the interpreter to warn about features that are
2549 deprecated and will be changed/removed in Python 3.0.
2550
Georg Brandl2134e752007-05-21 20:34:16 +00002551- Patch #1686487: you can now pass any mapping after '**' in function
2552 calls.
2553
Collin Winter62903052007-05-18 23:11:24 +00002554- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555 "except E as target:". This is to provide forwards compatibility
2556 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002557
Brett Cannon229cee22007-05-05 01:34:02 +00002558- Deprecate BaseException.message as per PEP 352.
2559
Georg Brandl3ee81df2008-05-17 18:14:43 +00002560- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002561 inherited from a builtin base.
2562
Vinay Sajip8549ce32007-05-06 17:53:37 +00002563- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002564 setting a plain string, ie don't expand to single letter identifiers.
2565
Raymond Hettinger13936692007-04-11 18:40:58 +00002566- Request #1191699: Slices can now be pickled.
2567
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002568- Request #1193128: str.translate() now allows a None argument for
2569 translations that only remove characters without re-mapping the
2570 remaining characters.
2571
Georg Brandl5cb76c12007-03-21 09:00:39 +00002572- Patch #1682205: a TypeError while unpacking an iterable is no longer
2573 masked by a generic one with the message "unpack non-sequence".
2574
Neal Norwitzaa754b72007-03-21 06:39:48 +00002575- Remove unused file Python/fmod.c.
2576
Guido van Rossum143b5642007-03-23 04:58:42 +00002577- Bug #1683368: The object.__init__() and object.__new__() methods are
2578 now stricter in rejecting excess arguments. The only time when
2579 either allows excess arguments is when it is not overridden and the
2580 other one is. For backwards compatibility, when both are
2581 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002582 warning later). Also, type.__init__() insists on the same signature
2583 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002584
Georg Brandl3ee81df2008-05-17 18:14:43 +00002585- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2586 object to complex using its __complex__() method before falling back
2587 to the __float__() method. Therefore, the functions in the cmath
2588 module now can operate on objects that define a __complex__()
2589 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002590
Georg Brandl3ee81df2008-05-17 18:14:43 +00002591- Patch #1623563: allow __class__ assignment for classes with
2592 __slots__. The old and the new class are still required to have the
2593 same slot names.

2599 ``object.__reduce_ex__()`` is called with an object that is faking
2600 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002601
Georg Brandl3ee81df2008-05-17 18:14:43 +00002602- Patch #1680015: Don't modify __slots__ tuple if it contains an

2606
Georg Brandl7b9c5552007-03-12 14:30:05 +00002607- Bug #1678647: write a newline after printing an exception in any
2608 case, even when converting the value to a string failed.
2609
Georg Brandl871f1bc2007-03-12 13:17:36 +00002610- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002611 its argument, if it exists. If not, it will work like before. This
2612 allows customizing the output of dir() in the presence of a
2613 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00002615- Patch #922167: Python no longer segfaults when faced with infinitely
2616 self-recursive reload() calls (as reported by bug #742342).
2617
Georg Brandl3ee81df2008-05-17 18:14:43 +00002618- Patch #1675981: remove unreachable code from ``type.__new__()``

Facundo Batistad918a652007-04-24 13:54:38 +00003136- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137 the client's request was successfully received, understood, and
3138 accepted. Now in these cases no error is raised in urllib (issue
3139 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003147- Added a timeout parameter to the constructor of other protocols
3148 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3149 work started with create_connection() and timeout in httplib, and
3150 closes patch #723312.
3151
Vinay Sajip8549ce32007-05-06 17:53:37 +00003152- Patch #1676823: Added create_connection() to socket.py, which may be

Facundo Batista07c78be2007-03-23 18:54:07 +00003155

Georg Brandl3ee81df2008-05-17 18:14:43 +00003178 AttributeError instead of an IOError when the server's response
3179 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003180

Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Patch #1429539: pdb now correctly initializes the __main__ module
3186 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003187 correctly now.
3188

3195
Georg Brandl3ee81df2008-05-17 18:14:43 +00003196- Patch #1530482: add pydoc.render_doc() which returns the
3197 documentation for a thing instead of paging it to stdout, which

3211
Georg Brandl92a6bae2007-03-13 17:43:32 +00003212- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003213 are set for invalid interpolation sequences that would lead to
3214 errors on reading back those values.

3268
Georg Brandl3ee81df2008-05-17 18:14:43 +00003269- unittest now verifies more of its assumptions. In particular,
3270 TestCase and TestSuite subclasses (not instances) are no longer
3271 accepted in TestSuite.addTest(). This should cause no
3272 incompatibility since it never made sense with ordinary subclasses
3273 -- the failure just occurred later, with a more cumbersome
3274 exception.

3284
Georg Brandl3ee81df2008-05-17 18:14:43 +00003285- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003663 time so that opening a database previously created with the DB_DUP
3664 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3665 opens. Specifically: dictionary assignment to a DB object will
3666 replace all values for a given key when the database allows
3667 duplicate values. DB users should use DB.put(k, v) when they want
3668 to store duplicates; not DB[k] = v.

3675 characters with ASCII value less than 32. Also, it correctly quotes
3676 dots only if they occur on a single line, as opposed to the previous
3677 behavior of quoting dots if they are the second character of any
3678 line.
