Georg Brandld2094602008-12-05 08:51:30 +0000456 method on file objects with closefd=False. The file descriptor is still

827What's New in Python 2.6.1
828==========================
829
830*Release date: 04-Dec-2008*
831
832Core and Builtins
833-----------------
834
835- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
836 interpreter to abort ("Fatal Python error: Could not reset the stack!")
837 instead of throwing a MemoryError.
838
839- Issue #4367: Python would segfault during compiling when the unicodedata
840 module couldn't be imported and \N escapes were present.
841
842- Issue #4348: Some bytearray methods returned that didn't cause any change to
843 the bytearray, returned the same bytearray instead of a copy.
844
845- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
846
847- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
848
849- Issue #4048: The parser module now correctly validates relative imports.
850
851- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
852 exec statement.
853
854- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
855 method does not return iterators for the 4th and 5th items.
856
857- Issue #4209: Enabling unicode_literals and the print_function in the same
858 __future__ import didn't work.
859
860- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
861 returned a path longer than MAX_PATH. (But It's doubtful this code path is
862 really executed because I cannot move to such directory on win2k)
863
864- Issue #4069: When set.remove(element) is used with a set element, the element
865 is temporarily replaced with an equivalent frozenset. But the eventual
866 KeyError would always report the empty frozenset([]) as the missing key. Now
867 it correctly refers to the initial element.
868
869- Fixed C99 style comments in several files. Python is now C89 compatible
870 again.

1016
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001017- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1018
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001019- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1020 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1021 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1022 ``printf`` function, whereas PyString_FromFormat has an independent
1023 implementation and uses "%zd" on all platforms for size_t values.
1024 This makes a difference on win64, where ``printf`` needs "%Id" to display
1025 64bit values.
1026
Benjamin Peterson97179b02008-09-09 20:55:01 +00001027- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1028 error.
1029
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001030- Issue #3777: long() applied to a float object now always return a long
1031 object; previously an int would be returned for small values. the __long__
1032 method is allowed to return either an int or a long, but the behaviour of
1033 float objects should not change to respect backward compatibility.
1034
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001035- Issue #3751: str.rpartition would perform a left-partition when called with
1036 a unicode argument.
1037
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001038- Issue #3683: Fix compilation when --without-threads is given.
1039
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001040- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001041 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001042 was correctly parsed but parsing of subsequent arguments failed.
1043
Vinay Sajip35e3b032008-09-01 14:33:59 +00001044- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001045 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1046 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1047 when given a tuple of classes as second argument, were looking up
1048 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1049 type object.
1050
Neal Norwitz18aa3882008-08-24 05:04:52 +00001051- Fix crashes on memory allocation failure found with failmalloc.
1052
1053- Fix memory leaks found with valgrind and update suppressions file.
1054
1055- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1056
1057- Fix problem using wrong name in decimal module reported by pychecker.
1058
Christian Heimes7d4c3172008-08-22 19:47:25 +00001059- Silenced another compiler warning about a used but not defined
1060 function 'stringlib_contains_obj'.

1063 ``__delslice__``.
1064
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001065- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1066 library targets in the Makefile.
1067
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001068- Issue #1204: The configure script now tests for additional libraries
1069 that may be required when linking against readline. This fixes issues
1070 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1089 with statements, or when the methods are invoked in the wrong order.
1090

Nick Coghland2e09382008-09-11 12:11:06 +00001093- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001094 return a list or None rather than a custom object.

1120 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1121 for catch_warnings() also led to an improvement in the raising of a
1122 DeprecationWarning related to warnings.warn_explicit().
1123
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001124- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001185What's New in Python 2.6 beta 3?
1186================================
1187
Barry Warsaw07a4a382008-08-21 01:15:08 +00001188*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001189
1190Core and Builtins
1191-----------------
1192
Guido van Rossumf8402962008-08-20 15:01:50 +00001193- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1194 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1195 extensions do not automatically benefit from the class attribute
1196 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1197 to their tp_flags field if they care. This is a backwards
1198 compatibility feature; in 3.0, all types will use the cache by
1199 default.
1200
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001201- Keyword arguments can now follow starred arguments. (``f(a, *args,
1202 keyword=23)`` is now valid syntax.)
1203
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001204- ctypes function pointers that are COM methods have a boolean True
1205 value again.
1206
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001207- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1208 by denying s# to parse objects that have a releasebuffer procedure,
1209 and introducing s*.
1210
Georg Brandl1e13ea92008-08-11 09:07:59 +00001211- Issue #3537: Fix an assertion failure when an empty but presized dict
1212 object was stored in the freelist.
1213
Mark Dickinsonb6467572008-08-04 21:30:09 +00001214- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1215 ValueError consistently across platforms.
1216
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001217- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1218 (64bit Unix, for example), unichr() would truncate its argument and return
1219 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1220
Neal Norwitze7d8be82008-07-31 17:17:14 +00001221- Apply security patches from Apple.
1222
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001223- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1224 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1225
Antoine Pitrou92f82162008-07-25 22:22:08 +00001226- Issue #1819: function calls with several named parameters are now on
1227 average 35% faster (as measured by pybench).
1228
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001229- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1230 the python debugger steps into a class statement: the free variables (local
1231 variables defined in an outer scope) would be deleted from the outer scope.
1232
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001233- Issue #2620: Overflow checking when allocating or reallocating memory
1234 was not always being done properly in some python types and extension
1235 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1236 all been updated to perform better checks and places in the code that
1237 would previously leak memory on the error path when such an allocation
1238 failed have been fixed.

1244
Benjamin Petersone977ad42008-08-20 01:42:01 +00001245- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1246 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1247
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001248- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1249 version reported by these tools does not necessarily follow the python
1250 version numbering scheme, so the module is less strict when parsing it.
1251
Nick Coghlanf70385a2008-08-18 12:42:46 +00001252- Issue #2235: Added Py3k warnings for types which will become unhashable
1253 under the stricter __hash__ inheritance rules in 3.0. Several types
1254 which did not meet the rules for hash invariants and were already
1255 unhashable in 3.0 have now been explicitly flagged as unhashable in
1256 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1257 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1258
Brett Cannon88f801d2008-08-18 00:46:22 +00001259- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1260 imported into the module but exposed as part of the module's API.
1261
Brett Cannon7b96f072008-08-18 00:41:11 +00001262- Remove an unneeded import of abc.ABCMeta from 'inspect'.

1267
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001268- Issue #3575: Incremental decoder's decode function now takes bytearray
1269 by using 's*' instead of 't#'.
1270
Jesus Cea585ad8a2009-07-02 15:37:21 +00001271- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001272 fails unicode conversion on 2nd parameter. (windows only)

Brett Cannonabe423e2008-08-16 21:47:07 +00001279
Facundo Batistaeb90b782008-08-16 14:44:07 +00001280- Issue #2776: fixed small issue when handling an URL with double slash
1281 after a 302 response in the case of not going through a proxy.
1282
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001283- Issue #2676: in the email package, content-type parsing was hanging on
1284 pathological input because of quadratic or exponential behaviour of a

Antoine Pitroude781a42008-08-09 12:43:23 +00001328 asking for a specific length. This problem only affected files opened

1372
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001373- Issue #643841: The language reference now provides more detailed

1385-----------------
1386
Georg Brandl3e483f62008-07-16 22:57:41 +00001387- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1388 its methods now allow for items objects that can be converted to
1389 an integer using operator.index().
1390
Mark Dickinson64b7e502008-07-16 09:40:03 +00001391- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1392 produced a ValueError instead of giving the correct float.
1393
Eric Smitha5fa5a22008-07-16 00:11:49 +00001394- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1395 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1396
Mark Dickinson7103aa42008-07-15 19:08:33 +00001397- Issue #3008: the float type has a new instance method 'float.hex'
1398 and a new class method 'float.fromhex' to convert floating-point
1399 numbers to and from hexadecimal strings, respectively.
1400
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001401- Issue #2235: __hash__ is once again inherited by default. To allow
1402 collections.Hashable to remain meaningful in the presence of the
1403 default hash implementation (object.__hash__), it is now possible
1404 to explicit block inheritance of hash by setting __hash__=None at
1405 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1406 level.
1407
Nick Coghlanb028f502008-07-13 14:52:36 +00001408- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1409 the parent module cannot be found while performing an absolute import.
1410 This means that an incorrectly defined __package__ attribute will
1411 now only prevent relative imports in that module rather than causing
1412 all imports from that module to fail.
1413
Nick Coghlan14ff9942008-07-08 14:21:42 +00001414- Issue #2517: Allow unicode messages in Exceptions again by correctly

1424 another thread's dictionary.
1425
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001426- Issue #3004: Minor change to slice.indices(): the start and stop
1427 arguments are now treated identically, making the behaviour easier
1428 to describe and understand. For example, slice(None, -10,
1429 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1430 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1431 10, -1).
1432
Georg Brandl278fc502008-07-19 12:46:12 +00001433- Issue #3219: Calling a function with repeated keyword arguments,
1434 f(a=2, a=23), would not cause a syntax error. This was a regression
1435 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001436
Georg Brandl278fc502008-07-19 12:46:12 +00001437- Issue #2862: Make int and float freelist management consistent with
1438 other freelists. Changes their CompactFreeList apis into

1445 api functions without holding the GIL, which could lead to a fatal
1446 error when they failed.
1447
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001448- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001473- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1474 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001475 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001476 content-length. The problem had been corrected in the 2.4 branch, but never
1477 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001492- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1494
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001495- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

1861 in Python 3.0.
Benjamin Peterson23681932008-05-12 21:42:13 +00001862
Vinay Sajip9828b7e2008-06-17 11:04:02 +00001863- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001864 environment to control the '-arch' flags that are used to build
1865 an extension. This was added for compatibility with Apple's build
1866 of Python.
1867
1868- The bundled OSX-specific copy of libbffi is now in sync with the version
1869 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
1870
Georg Brandl25c34082008-08-18 23:09:49 +00001871- The threading module gained aliases for names that will be removed in the

1880
Brett Cannonb61d8012008-05-11 23:39:04 +00001881- ``Lib/lib-old`` is now added to sys.path.
1882
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001883- On MacOS X it is now possible to install the framework in 64-bit
1884 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001885 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001886
1887 This is controlled by the configure argument ``--with-universal-archs``:
1888
1889 - ``--with-universal-archs=all``: install 4-way universal
1890
1891 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1892
1893 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1894
1895 This option should be used in combination with ``--enable-universalsdk=``.
1896
1897 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00001947- Issue #1631171: Re-implement the 'warnings' module in C (the
1948 original Python code has been kept as backup). This will allow for
1949 using the 'warning's machinery in such places as the parser where
1950 use of pure Python code is not possible. Both the ``showarning()``
1951 and ``formatwarning()`` gain an optional 'line' argument which is
1952 not called by default for backwards-compatibility reasons. Setting
1953 ``warnings.showwarning()`` to an implementation that lacks support
1954 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001996- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001997 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002017- Issue #2550: The approach used by client/server code for obtaining
2018 ports to listen on in network-oriented tests has been refined in an
2019 effort to facilitate running multiple instances of the entire
2020 regression test suite in parallel without issue.
2021 test_support.bind_port() has been fixed such that it will always
2022 return a unique port -- which wasn't always the case with the
2023 previous implementation, especially if socket options had been set
2024 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2025 new implementation of bind_port() will actually raise an exception
2026 if it is passed an AF_INET/SOCK_STREAM socket with either the
2027 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2028 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2029 the socket it's been passed. This currently only applies to
2030 Windows. This option prevents any other sockets from binding to the
2031 host/port we've bound to, thus removing the possibility of the
2032 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2033 when a second SOCK_STREAM socket binds and accepts to a host/port
2034 that's already been bound by another socket. The optional preferred
2035 port parameter to bind_port() has been removed. Under no
2036 circumstances should tests be hard coding ports!
2037
2038 test_support.find_unused_port() has also been introduced, which will
2039 pass a temporary socket object to bind_port() in order to obtain an
2040 unused port. The temporary socket object is then closed and
2041 deleted, and the port is returned. This method should only be used
2042 for obtaining an unused port in order to pass to an external program
2043 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2044 a parameter to a server-oriented class that doesn't give you direct
2045 access to the underlying socket used.
2046
2047 Finally, test_support.HOST has been introduced, which should be used
2048 for the host argument of any relevant socket calls (i.e. bind and
2049 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002050
2051 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002052 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002053 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2054 test_asynchat and test_socket_ssl.
2055
Georg Brandl3ee81df2008-05-17 18:14:43 +00002056 It is now possible for multiple instances of the regression test
2057 suite to run in parallel without issue.

2323Core and builtins
2324-----------------
2325
Fred Drakea8ee94b2008-03-01 02:45:07 +00002326- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002327 644. The mode is now inherited from the py file.

2330
2331- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002332
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002333- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002334 issue 215555 for a discussion.
2335
Eric Smitha73fbe72008-02-23 03:09:44 +00002336- Added the future_builtins module, which contains hex() and oct().
2337 These are the PEP 3127 version of these functions, designed to be
2338 compatible with the hex() and oct() builtins from Python 3.0. They
2339 differ slightly in their output formats from the existing, unchanged
2340 Python 2.6 builtins. The expected usage of the future_builtins
2341 module is:
2342 from future_builtins import hex, oct
2343
Eric Smith7ef40bf2008-02-20 23:34:22 +00002344- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2345 exponents for exponents with absolute value < 100. Follows C99
2346 standard. This is a change on Windows, which would use 3 digits.
2347 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2348 so that any alterations it does to the resulting string will be
2349 available in stringlib/formatter.h (for float.__format__).
2350
Eric Smith5a3c1352008-02-19 13:21:56 +00002351- Implemented PEP 3101, Advanced String Formatting. This adds a new
2352 builtin format(); a format() method for str and unicode; a
2353 __format__() method to object, str, unicode, int, long, float, and
2354 datetime; the class string.Formatter; and the C API
2355 PyObject_Format().
2356
Georg Brandl3ee81df2008-05-17 18:14:43 +00002357- Fixed several potential crashes, all caused by specially crafted
2358 __del__ methods exploiting objects in temporarily inconsistent
2359 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002360
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002361- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002362 prevent a possible crash: an Abstract Base Class would try to access
2363 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002364

2366 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002368- Clear all free lists during a gc.collect() of the highest generation
2369 in order to allow pymalloc to free more arenas. Python may give back
2370 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002371
Georg Brandl3ee81df2008-05-17 18:14:43 +00002372- Issue #2045: Fix an infinite recursion triggered when printing a
2373 subclass of collections.defaultdict, if its default_factory is set
2374 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002375
Christian Heimesf75dbef2008-02-08 00:11:31 +00002376- Fixed a minor memory leak in dictobject.c. The content of the free
2377 list was not freed on interpreter shutdown.
2378
Georg Brandl3ee81df2008-05-17 18:14:43 +00002379- Limit free list of method and builtin function objects to 256
2380 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002381
Georg Brandl3ee81df2008-05-17 18:14:43 +00002382- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2383 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002384 to compact the internal free lists of pre-allocted ints and floats.
2385
Georg Brandl3ee81df2008-05-17 18:14:43 +00002386- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2387 calls. Python expected the return type int but the fork familie
2388 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002389
Georg Brandl3ee81df2008-05-17 18:14:43 +00002390- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2391 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002392
Georg Brandl3ee81df2008-05-17 18:14:43 +00002393- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2394 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002395
Georg Brandl3ee81df2008-05-17 18:14:43 +00002396- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2397 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002399- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2400 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002401
Georg Brandl3ee81df2008-05-17 18:14:43 +00002402- Patch #1473257: generator objects gain a gi_code attribute. This is
2403 the same object as the func_code attribute of the function that
2404 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002405
Georg Brandl3ee81df2008-05-17 18:14:43 +00002406- Issue #1920: "while 0" statements were completely removed by the
2407 compiler, even in the presence of an "else" clause, which is
2408 supposed to be run when the condition is false. Now the compiler
2409 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002410
Guido van Rossumeead05f2008-01-24 18:21:02 +00002411- A few crashers fixed: weakref_in_del.py (issue #1377858);
2412 loosing_dict_ref.py (issue #1303614, test67.py);
2413 borrowed_ref_[34].py (not in tracker).
2414
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002415- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002416 suppressed while an extension is loaded by calling SetErrorMode in
2417 dynload_win.c. The error is still reported properly.
2418
Georg Brandl3ee81df2008-05-17 18:14:43 +00002419- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002420 several extension methods and modules do not work without unicode
2421 support.
2422
Georg Brandl26543b12008-01-21 18:36:51 +00002423- Issue #1882: when compiling code from a string, encoding cookies in the
2424 second line of code were not always recognized correctly.
2425
Georg Brandl14404b62008-01-19 19:27:05 +00002426- Issue #1679: "0x" was taken as a valid integer literal.
2427
Georg Brandl6caad7d2008-01-26 14:19:22 +00002428- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002429 added.
2430
Christian Heimesc94e2b52008-01-14 04:13:37 +00002431- sys.float_info / PyFloat_GetInfo: The floating point information
2432 object was converted from a dict to a specialized structseq object.
2433
Georg Brandl3ee81df2008-05-17 18:14:43 +00002434- Patch #1816: Added sys.flags structseq. It exposes the status of
2435 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002436
Georg Brandl3ee81df2008-05-17 18:14:43 +00002437- Objects/structseq.c: Implemented new structseq representation. The
2438 patch makes structseqs (e.g. the return value of os.stat) more
2439 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002440
Georg Brandl3ee81df2008-05-17 18:14:43 +00002441- Patch #1700288: added a type attribute cache that caches method
2442 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002443
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002444- Bug #1776: __import__() no longer accepts filenames on any platform.
2445 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002446
Georg Brandlaed6c662008-01-07 17:25:53 +00002447- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2448
Georg Brandl3ee81df2008-05-17 18:14:43 +00002449- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2450 envvar and sys.dont_write_bytecode attribute. All these can be set
2451 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002452
Georg Brandl3ee81df2008-05-17 18:14:43 +00002453- Improve some exception messages when Windows fails to load an
2454 extension module. Now we get for example '%1 is not a valid Win32
2455 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002456

Georg Brandl3ee81df2008-05-17 18:14:43 +00002459- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2460 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002461
Christian Heimes0a8143f2007-12-18 23:22:54 +00002462- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002463 and INF. float("nan"), float("inf") and float("-inf") now work on
2464 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002465
Georg Brandl3ee81df2008-05-17 18:14:43 +00002466- Compiler now generates simpler and faster code for dictionary
2467 literals. The oparg for BUILD_MAP now indicates an estimated
2468 dictionary size. There is a new opcode, STORE_MAP, for adding
2469 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002498- Patch #1739468: Directories and zipfiles containing a __main__.py
2499 file can now be directly executed by passing their name to the
2500 interpreter. The directory/zipfile is automatically inserted as the
2501 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002502
Georg Brandl3ee81df2008-05-17 18:14:43 +00002503- Issue #1265: Fix a problem with sys.settrace, if the tracing
2504 function uses a generator expression when at the same time the
2505 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002506
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002507- sets and frozensets now have an isdisjoint() method.
2508

2510
Neal Norwitz44f326e2007-10-05 05:29:17 +00002511- Fix warnings found by the new version of the Coverity checker.
2512
Georg Brandl3ee81df2008-05-17 18:14:43 +00002513- The enumerate() builtin function is no longer bounded to sequences
2514 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2515 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002516
Georg Brandl3ee81df2008-05-17 18:14:43 +00002517- Issue #1686386: Tuple's tp_repr did not take into account the
2518 possibility of having a self-referential tuple, which is possible
2519 from C code. Nor did object's tp_str consider that a type's tp_str
2520 could do something that could lead to an inifinite recursion.
2521 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2522 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002523
Georg Brandl3ee81df2008-05-17 18:14:43 +00002524- Issue #1164: It was possible to trigger deadlock when using the
2525 'print' statement to write to a file since the GIL was not released
2526 as needed. Now PyObject_Print() does the right thing along with
2527 various tp_print implementations of the built-in types and those in
2528 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002529
Georg Brandl3ee81df2008-05-17 18:14:43 +00002530- Issue #1147: Exceptions were directly allowing string exceptions in
2531 their throw() method even though string exceptions no longer
2532 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002533
Georg Brandl3ee81df2008-05-17 18:14:43 +00002534- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002536
Brett Cannon1e534b52007-09-07 04:18:30 +00002537- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002538 PyObject_Call() never calling back out to Python code to trigger
2539 recursion depth updates/checks. Required the creation of a static
2540 RuntimeError instance in case normalizing an exception put the
2541 recursion check value past its limit. Fixes crashers
2542 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002543

Neal Norwitz0ac60192007-05-27 04:08:54 +00002557- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002558 __*__ attributes. (Some already existed, e.g., __doc__ and
2559 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002560
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002561- Add -3 option to the interpreter to warn about features that are
2562 deprecated and will be changed/removed in Python 3.0.
2563
Georg Brandl2134e752007-05-21 20:34:16 +00002564- Patch #1686487: you can now pass any mapping after '**' in function
2565 calls.
2566
Collin Winter62903052007-05-18 23:11:24 +00002567- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002568 "except E as target:". This is to provide forwards compatibility
2569 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002570
Brett Cannon229cee22007-05-05 01:34:02 +00002571- Deprecate BaseException.message as per PEP 352.
2572
Georg Brandl3ee81df2008-05-17 18:14:43 +00002573- Issue #1303614: don't expose object's __dict__ when the dict is

2575
Vinay Sajip8549ce32007-05-06 17:53:37 +00002576- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002577 setting a plain string, ie don't expand to single letter identifiers.
2578
Raymond Hettinger13936692007-04-11 18:40:58 +00002579- Request #1191699: Slices can now be pickled.
2580
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002581- Request #1193128: str.translate() now allows a None argument for

2583 remaining characters.
2584
Georg Brandl5cb76c12007-03-21 09:00:39 +00002585- Patch #1682205: a TypeError while unpacking an iterable is no longer
2586 masked by a generic one with the message "unpack non-sequence".
2587
Neal Norwitzaa754b72007-03-21 06:39:48 +00002588- Remove unused file Python/fmod.c.
2589
Guido van Rossum143b5642007-03-23 04:58:42 +00002590- Bug #1683368: The object.__init__() and object.__new__() methods are
2591 now stricter in rejecting excess arguments. The only time when
2592 either allows excess arguments is when it is not overridden and the
2593 other one is. For backwards compatibility, when both are
2594 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002595 warning later). Also, type.__init__() insists on the same signature
2596 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002598- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2599 object to complex using its __complex__() method before falling back
2600 to the __float__() method. Therefore, the functions in the cmath
2601 module now can operate on objects that define a __complex__()
2602 method.

2621 case, even when converting the value to a string failed.
2622
Georg Brandl871f1bc2007-03-12 13:17:36 +00002623- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002624 its argument, if it exists. If not, it will work like before. This
2625 allows customizing the output of dir() in the presence of a
2626 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002638- Patch #703779: unset __file__ in __main__ after running a file. This

2709 embedded in the string to convert.
2710
Georg Brandl846f73a2006-10-08 07:11:54 +00002711- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00002741- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003150 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003191 AttributeError instead of an IOError when the server's response
3192 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003676 time so that opening a database previously created with the DB_DUP
3677 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3678 opens. Specifically: dictionary assignment to a DB object will
3679 replace all values for a given key when the database allows
3680 duplicate values. DB users should use DB.put(k, v) when they want
3681 to store duplicates; not DB[k] = v.

3688 characters with ASCII value less than 32. Also, it correctly quotes
3689 dots only if they occur on a single line, as opposed to the previous
3690 behavior of quoting dots if they are the second character of any
3691 line.
