Vinay Sajip6badbe92009-01-20 22:49:13 +0000449- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000450 method on file objects with closefd=False. The file descriptor is still

821What's New in Python 2.6.1
822==========================
823
824*Release date: 04-Dec-2008*
825
826Core and Builtins
827-----------------
828
829- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
830 interpreter to abort ("Fatal Python error: Could not reset the stack!")
831 instead of throwing a MemoryError.
832
833- Issue #4367: Python would segfault during compiling when the unicodedata
834 module couldn't be imported and \N escapes were present.
835
836- Issue #4348: Some bytearray methods returned that didn't cause any change to
837 the bytearray, returned the same bytearray instead of a copy.
838
839- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
840
841- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
842
843- Issue #4048: The parser module now correctly validates relative imports.
844
845- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
846 exec statement.
847
848- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
849 method does not return iterators for the 4th and 5th items.
850
851- Issue #4209: Enabling unicode_literals and the print_function in the same
852 __future__ import didn't work.
853
854- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
855 returned a path longer than MAX_PATH. (But It's doubtful this code path is
856 really executed because I cannot move to such directory on win2k)
857
858- Issue #4069: When set.remove(element) is used with a set element, the element
859 is temporarily replaced with an equivalent frozenset. But the eventual
860 KeyError would always report the empty frozenset([]) as the missing key. Now
861 it correctly refers to the initial element.
862
863- Fixed C99 style comments in several files. Python is now C89 compatible
864 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001011- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1012
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001013- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1014 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1015 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1016 ``printf`` function, whereas PyString_FromFormat has an independent
1017 implementation and uses "%zd" on all platforms for size_t values.
1018 This makes a difference on win64, where ``printf`` needs "%Id" to display
1019 64bit values.
1020
Benjamin Peterson97179b02008-09-09 20:55:01 +00001021- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1022 error.
1023
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001024- Issue #3777: long() applied to a float object now always return a long
1025 object; previously an int would be returned for small values. the __long__
1026 method is allowed to return either an int or a long, but the behaviour of
1027 float objects should not change to respect backward compatibility.
1028
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001029- Issue #3751: str.rpartition would perform a left-partition when called with
1030 a unicode argument.
1031
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001032- Issue #3683: Fix compilation when --without-threads is given.
1033
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001034- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001035 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001036 was correctly parsed but parsing of subsequent arguments failed.
1037
Vinay Sajip35e3b032008-09-01 14:33:59 +00001038- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001039 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1040 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1041 when given a tuple of classes as second argument, were looking up
1042 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1043 type object.
1044
Neal Norwitz18aa3882008-08-24 05:04:52 +00001045- Fix crashes on memory allocation failure found with failmalloc.
1046
1047- Fix memory leaks found with valgrind and update suppressions file.
1048
1049- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1050
1051- Fix problem using wrong name in decimal module reported by pychecker.
1052
Christian Heimes7d4c3172008-08-22 19:47:25 +00001053- Silenced another compiler warning about a used but not defined
1054 function 'stringlib_contains_obj'.

1057 ``__delslice__``.
1058
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001059- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1060 library targets in the Makefile.
1061
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001062- Issue #1204: The configure script now tests for additional libraries
1063 that may be required when linking against readline. This fixes issues
1064 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001081- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1082 silent misbehaviour when a single instance is nested in multiple
1083 with statements, or when the methods are invoked in the wrong order.
1084
Vinay Sajip844f7412008-09-09 13:42:08 +00001085- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

1114 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1115 for catch_warnings() also led to an improvement in the raising of a
1116 DeprecationWarning related to warnings.warn_explicit().
1117
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001118- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001179What's New in Python 2.6 beta 3?
1180================================
1181
Barry Warsaw07a4a382008-08-21 01:15:08 +00001182*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001183
1184Core and Builtins
1185-----------------
1186
Guido van Rossumf8402962008-08-20 15:01:50 +00001187- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1188 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1189 extensions do not automatically benefit from the class attribute
1190 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1191 to their tp_flags field if they care. This is a backwards
1192 compatibility feature; in 3.0, all types will use the cache by
1193 default.
1194
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001195- Keyword arguments can now follow starred arguments. (``f(a, *args,
1196 keyword=23)`` is now valid syntax.)
1197
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001198- ctypes function pointers that are COM methods have a boolean True
1199 value again.
1200
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001201- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1202 by denying s# to parse objects that have a releasebuffer procedure,
1203 and introducing s*.
1204
Georg Brandl1e13ea92008-08-11 09:07:59 +00001205- Issue #3537: Fix an assertion failure when an empty but presized dict
1206 object was stored in the freelist.
1207
Mark Dickinsonb6467572008-08-04 21:30:09 +00001208- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1209 ValueError consistently across platforms.
1210
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001211- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1212 (64bit Unix, for example), unichr() would truncate its argument and return
1213 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1214
Neal Norwitze7d8be82008-07-31 17:17:14 +00001215- Apply security patches from Apple.
1216
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001217- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1218 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1219
Antoine Pitrou92f82162008-07-25 22:22:08 +00001220- Issue #1819: function calls with several named parameters are now on
1221 average 35% faster (as measured by pybench).
1222
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001223- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1224 the python debugger steps into a class statement: the free variables (local
1225 variables defined in an outer scope) would be deleted from the outer scope.
1226
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001227- Issue #2620: Overflow checking when allocating or reallocating memory
1228 was not always being done properly in some python types and extension
1229 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1230 all been updated to perform better checks and places in the code that
1231 would previously leak memory on the error path when such an allocation
1232 failed have been fixed.
1233

1238
Benjamin Petersone977ad42008-08-20 01:42:01 +00001239- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1240 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1241
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001242- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1243 version reported by these tools does not necessarily follow the python
1244 version numbering scheme, so the module is less strict when parsing it.
1245
Nick Coghlanf70385a2008-08-18 12:42:46 +00001246- Issue #2235: Added Py3k warnings for types which will become unhashable
1247 under the stricter __hash__ inheritance rules in 3.0. Several types
1248 which did not meet the rules for hash invariants and were already
1249 unhashable in 3.0 have now been explicitly flagged as unhashable in
1250 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1251 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1252
Brett Cannon88f801d2008-08-18 00:46:22 +00001253- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1254 imported into the module but exposed as part of the module's API.
1255
Brett Cannon7b96f072008-08-18 00:41:11 +00001256- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1257
Brett Cannon46225e72008-08-18 00:36:52 +00001258- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001260- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1261
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001262- Issue #3575: Incremental decoder's decode function now takes bytearray
1263 by using 's*' instead of 't#'.
1264
Jesus Cea585ad8a2009-07-02 15:37:21 +00001265- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001266 fails unicode conversion on 2nd parameter. (windows only)
1267
Facundo Batista94f243a2008-08-17 03:38:39 +00001268- Issue 2464. urllib2 now supports a malformation in the URL received
1269 in a redirect.
1270
Brett Cannonabe423e2008-08-16 21:47:07 +00001271- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001272 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001273
Facundo Batistaeb90b782008-08-16 14:44:07 +00001274- Issue #2776: fixed small issue when handling an URL with double slash
1275 after a 302 response in the case of not going through a proxy.
1276
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001277- Issue #2676: in the email package, content-type parsing was hanging on
1278 pathological input because of quadratic or exponential behaviour of a
1279 regular expression.
1280
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001281- Issue #3476: binary buffered reading through the new "io" library is now
1282 thread-safe.
1283
Brett Cannonbf3157b2008-08-14 05:00:03 +00001284- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1285 since mimetools itself is deprecated. Because modules are cached, all
1286 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1287
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001288- Issue #3134: shutil referenced undefined WindowsError symbol.

Antoine Pitroude781a42008-08-09 12:43:23 +00001322 asking for a specific length. This problem only affected files opened

1365 interaction with the tp_hash slot (added in 2.6b2) are now documented
1366
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001367- Issue #643841: The language reference now provides more detailed

1379-----------------
1380
Georg Brandl3e483f62008-07-16 22:57:41 +00001381- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1382 its methods now allow for items objects that can be converted to
1383 an integer using operator.index().
1384
Mark Dickinson64b7e502008-07-16 09:40:03 +00001385- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1386 produced a ValueError instead of giving the correct float.
1387
Eric Smitha5fa5a22008-07-16 00:11:49 +00001388- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1389 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1390
Mark Dickinson7103aa42008-07-15 19:08:33 +00001391- Issue #3008: the float type has a new instance method 'float.hex'
1392 and a new class method 'float.fromhex' to convert floating-point
1393 numbers to and from hexadecimal strings, respectively.
1394
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001395- Issue #2235: __hash__ is once again inherited by default. To allow
1396 collections.Hashable to remain meaningful in the presence of the
1397 default hash implementation (object.__hash__), it is now possible
1398 to explicit block inheritance of hash by setting __hash__=None at
1399 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1400 level.
1401
Nick Coghlanb028f502008-07-13 14:52:36 +00001402- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1403 the parent module cannot be found while performing an absolute import.
1404 This means that an incorrectly defined __package__ attribute will
1405 now only prevent relative imports in that module rather than causing
1406 all imports from that module to fail.
1407
Nick Coghlan14ff9942008-07-08 14:21:42 +00001408- Issue #2517: Allow unicode messages in Exceptions again by correctly

1418 another thread's dictionary.
1419
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001420- Issue #3004: Minor change to slice.indices(): the start and stop
1421 arguments are now treated identically, making the behaviour easier
1422 to describe and understand. For example, slice(None, -10,
1423 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1424 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1425 10, -1).
1426
Georg Brandl278fc502008-07-19 12:46:12 +00001427- Issue #3219: Calling a function with repeated keyword arguments,
1428 f(a=2, a=23), would not cause a syntax error. This was a regression
1429 from 2.4 caused by the switch to the new compiler.

1432 other freelists. Changes their CompactFreeList apis into

1439 api functions without holding the GIL, which could lead to a fatal
1440 error when they failed.
1441
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001442- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001467- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1468 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001469 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001470 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001486- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1859 an extension. This was added for compatibility with Apple's build
1860 of Python.
1861
1862- The bundled OSX-specific copy of libbffi is now in sync with the version
1863 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
1864
Georg Brandl25c34082008-08-18 23:09:49 +00001865- The threading module gained aliases for names that will be removed in the
1866 3.x series.

1874
Brett Cannonb61d8012008-05-11 23:39:04 +00001875- ``Lib/lib-old`` is now added to sys.path.
1876
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001877- On MacOS X it is now possible to install the framework in 64-bit
1878 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001879 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001880
1881 This is controlled by the configure argument ``--with-universal-archs``:
1882
1883 - ``--with-universal-archs=all``: install 4-way universal
1884
1885 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1886
1887 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1888
1889 This option should be used in combination with ``--enable-universalsdk=``.
1890
1891 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 +00001941- Issue #1631171: Re-implement the 'warnings' module in C (the
1942 original Python code has been kept as backup). This will allow for
1943 using the 'warning's machinery in such places as the parser where
1944 use of pure Python code is not possible. Both the ``showarning()``
1945 and ``formatwarning()`` gain an optional 'line' argument which is
1946 not called by default for backwards-compatibility reasons. Setting
1947 ``warnings.showwarning()`` to an implementation that lacks support
1948 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001973- The getpass module has been improved on Unix. It now uses /dev/tty
1974 by default and uses stderr instead of stdout. A GetPassWarning is
1975 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001990- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001991 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002011- Issue #2550: The approach used by client/server code for obtaining
2012 ports to listen on in network-oriented tests has been refined in an
2013 effort to facilitate running multiple instances of the entire
2014 regression test suite in parallel without issue.
2015 test_support.bind_port() has been fixed such that it will always
2016 return a unique port -- which wasn't always the case with the
2017 previous implementation, especially if socket options had been set
2018 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2019 new implementation of bind_port() will actually raise an exception
2020 if it is passed an AF_INET/SOCK_STREAM socket with either the
2021 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2022 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2023 the socket it's been passed. This currently only applies to
2024 Windows. This option prevents any other sockets from binding to the
2025 host/port we've bound to, thus removing the possibility of the
2026 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2027 when a second SOCK_STREAM socket binds and accepts to a host/port
2028 that's already been bound by another socket. The optional preferred
2029 port parameter to bind_port() has been removed. Under no
2030 circumstances should tests be hard coding ports!
2031
2032 test_support.find_unused_port() has also been introduced, which will
2033 pass a temporary socket object to bind_port() in order to obtain an
2034 unused port. The temporary socket object is then closed and
2035 deleted, and the port is returned. This method should only be used
2036 for obtaining an unused port in order to pass to an external program
2037 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2038 a parameter to a server-oriented class that doesn't give you direct
2039 access to the underlying socket used.
2040
2041 Finally, test_support.HOST has been introduced, which should be used
2042 for the host argument of any relevant socket calls (i.e. bind and
2043 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002044
2045 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002046 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002047 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2048 test_asynchat and test_socket_ssl.
2049
Georg Brandl3ee81df2008-05-17 18:14:43 +00002050 It is now possible for multiple instances of the regression test
2051 suite to run in parallel without issue.

2318-----------------
2319
Fred Drakea8ee94b2008-03-01 02:45:07 +00002320- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002321 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002323- Issue #2067: file.__exit__() now calls subclasses' close() method.
2324
2325- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002326
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002327- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002328 issue 215555 for a discussion.
2329
Eric Smitha73fbe72008-02-23 03:09:44 +00002330- Added the future_builtins module, which contains hex() and oct().
2331 These are the PEP 3127 version of these functions, designed to be
2332 compatible with the hex() and oct() builtins from Python 3.0. They
2333 differ slightly in their output formats from the existing, unchanged
2334 Python 2.6 builtins. The expected usage of the future_builtins
2335 module is:
2336 from future_builtins import hex, oct
2337
Eric Smith7ef40bf2008-02-20 23:34:22 +00002338- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2339 exponents for exponents with absolute value < 100. Follows C99
2340 standard. This is a change on Windows, which would use 3 digits.
2341 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2342 so that any alterations it does to the resulting string will be
2343 available in stringlib/formatter.h (for float.__format__).
2344
Eric Smith5a3c1352008-02-19 13:21:56 +00002345- Implemented PEP 3101, Advanced String Formatting. This adds a new
2346 builtin format(); a format() method for str and unicode; a
2347 __format__() method to object, str, unicode, int, long, float, and
2348 datetime; the class string.Formatter; and the C API
2349 PyObject_Format().
2350
Georg Brandl3ee81df2008-05-17 18:14:43 +00002351- Fixed several potential crashes, all caused by specially crafted
2352 __del__ methods exploiting objects in temporarily inconsistent
2353 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002354
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002355- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002356 prevent a possible crash: an Abstract Base Class would try to access
2357 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002358

Georg Brandl3ee81df2008-05-17 18:14:43 +00002362- Clear all free lists during a gc.collect() of the highest generation
2363 in order to allow pymalloc to free more arenas. Python may give back
2364 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002365
Georg Brandl3ee81df2008-05-17 18:14:43 +00002366- Issue #2045: Fix an infinite recursion triggered when printing a
2367 subclass of collections.defaultdict, if its default_factory is set
2368 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002369
Christian Heimesf75dbef2008-02-08 00:11:31 +00002370- Fixed a minor memory leak in dictobject.c. The content of the free
2371 list was not freed on interpreter shutdown.
2372
Georg Brandl3ee81df2008-05-17 18:14:43 +00002373- Limit free list of method and builtin function objects to 256
2374 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002375
Georg Brandl3ee81df2008-05-17 18:14:43 +00002376- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2377 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002378 to compact the internal free lists of pre-allocted ints and floats.
2379
Georg Brandl3ee81df2008-05-17 18:14:43 +00002380- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2381 calls. Python expected the return type int but the fork familie
2382 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002383
Georg Brandl3ee81df2008-05-17 18:14:43 +00002384- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2385 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002386
Georg Brandl3ee81df2008-05-17 18:14:43 +00002387- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2388 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002389
Georg Brandl3ee81df2008-05-17 18:14:43 +00002390- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2391 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002392
Georg Brandl3ee81df2008-05-17 18:14:43 +00002393- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2394 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002395
Georg Brandl3ee81df2008-05-17 18:14:43 +00002396- Patch #1473257: generator objects gain a gi_code attribute. This is
2397 the same object as the func_code attribute of the function that
2398 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002399
Georg Brandl3ee81df2008-05-17 18:14:43 +00002400- Issue #1920: "while 0" statements were completely removed by the
2401 compiler, even in the presence of an "else" clause, which is
2402 supposed to be run when the condition is false. Now the compiler
2403 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002404
Guido van Rossumeead05f2008-01-24 18:21:02 +00002405- A few crashers fixed: weakref_in_del.py (issue #1377858);
2406 loosing_dict_ref.py (issue #1303614, test67.py);
2407 borrowed_ref_[34].py (not in tracker).
2408
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002409- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002410 suppressed while an extension is loaded by calling SetErrorMode in
2411 dynload_win.c. The error is still reported properly.
2412
Georg Brandl3ee81df2008-05-17 18:14:43 +00002413- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002414 several extension methods and modules do not work without unicode
2415 support.
2416
Georg Brandl26543b12008-01-21 18:36:51 +00002417- Issue #1882: when compiling code from a string, encoding cookies in the
2418 second line of code were not always recognized correctly.
2419
Georg Brandl14404b62008-01-19 19:27:05 +00002420- Issue #1679: "0x" was taken as a valid integer literal.
2421
Georg Brandl6caad7d2008-01-26 14:19:22 +00002422- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002423 added.
2424
Christian Heimesc94e2b52008-01-14 04:13:37 +00002425- sys.float_info / PyFloat_GetInfo: The floating point information
2426 object was converted from a dict to a specialized structseq object.
2427
Georg Brandl3ee81df2008-05-17 18:14:43 +00002428- Patch #1816: Added sys.flags structseq. It exposes the status of
2429 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002430
Georg Brandl3ee81df2008-05-17 18:14:43 +00002431- Objects/structseq.c: Implemented new structseq representation. The
2432 patch makes structseqs (e.g. the return value of os.stat) more
2433 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002434
Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- Patch #1700288: added a type attribute cache that caches method
2436 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002437
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002438- Bug #1776: __import__() no longer accepts filenames on any platform.
2439 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002440
Georg Brandlaed6c662008-01-07 17:25:53 +00002441- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2442
Georg Brandl3ee81df2008-05-17 18:14:43 +00002443- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2444 envvar and sys.dont_write_bytecode attribute. All these can be set
2445 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002446
Georg Brandl3ee81df2008-05-17 18:14:43 +00002447- Improve some exception messages when Windows fails to load an
2448 extension module. Now we get for example '%1 is not a valid Win32
2449 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002450

Christian Heimes0a8143f2007-12-18 23:22:54 +00002456- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002457 and INF. float("nan"), float("inf") and float("-inf") now work on
2458 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002459
Georg Brandl3ee81df2008-05-17 18:14:43 +00002460- Compiler now generates simpler and faster code for dictionary
2461 literals. The oparg for BUILD_MAP now indicates an estimated
2462 dictionary size. There is a new opcode, STORE_MAP, for adding
2463 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002492- Patch #1739468: Directories and zipfiles containing a __main__.py
2493 file can now be directly executed by passing their name to the
2494 interpreter. The directory/zipfile is automatically inserted as the
2495 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002497- Issue #1265: Fix a problem with sys.settrace, if the tracing
2498 function uses a generator expression when at the same time the
2499 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002500
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002501- sets and frozensets now have an isdisjoint() method.
2502

2504
Neal Norwitz44f326e2007-10-05 05:29:17 +00002505- Fix warnings found by the new version of the Coverity checker.
2506
Georg Brandl3ee81df2008-05-17 18:14:43 +00002507- The enumerate() builtin function is no longer bounded to sequences
2508 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2509 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002510
Georg Brandl3ee81df2008-05-17 18:14:43 +00002511- Issue #1686386: Tuple's tp_repr did not take into account the
2512 possibility of having a self-referential tuple, which is possible
2513 from C code. Nor did object's tp_str consider that a type's tp_str
2514 could do something that could lead to an inifinite recursion.
2515 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2516 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002517
Georg Brandl3ee81df2008-05-17 18:14:43 +00002518- Issue #1164: It was possible to trigger deadlock when using the
2519 'print' statement to write to a file since the GIL was not released
2520 as needed. Now PyObject_Print() does the right thing along with
2521 various tp_print implementations of the built-in types and those in
2522 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002523
Georg Brandl3ee81df2008-05-17 18:14:43 +00002524- Issue #1147: Exceptions were directly allowing string exceptions in
2525 their throw() method even though string exceptions no longer
2526 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002527
Georg Brandl3ee81df2008-05-17 18:14:43 +00002528- Issue #1096: Prevent a segfault from getting the repr of a very
2529 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002530
Brett Cannon1e534b52007-09-07 04:18:30 +00002531- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002532 PyObject_Call() never calling back out to Python code to trigger
2533 recursion depth updates/checks. Required the creation of a static
2534 RuntimeError instance in case normalizing an exception put the
2535 recursion check value past its limit. Fixes crashers
2536 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002537
Georg Brandl3ee81df2008-05-17 18:14:43 +00002538- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002551- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002552 __*__ attributes. (Some already existed, e.g., __doc__ and
2553 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002554
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002555- Add -3 option to the interpreter to warn about features that are
2556 deprecated and will be changed/removed in Python 3.0.
2557
Georg Brandl2134e752007-05-21 20:34:16 +00002558- Patch #1686487: you can now pass any mapping after '**' in function
2559 calls.
2560
Collin Winter62903052007-05-18 23:11:24 +00002561- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002562 "except E as target:". This is to provide forwards compatibility
2563 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002564
Brett Cannon229cee22007-05-05 01:34:02 +00002565- Deprecate BaseException.message as per PEP 352.
2566
Georg Brandl3ee81df2008-05-17 18:14:43 +00002567- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002568 inherited from a builtin base.
2569
Vinay Sajip8549ce32007-05-06 17:53:37 +00002570- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002571 setting a plain string, ie don't expand to single letter identifiers.
2572
Raymond Hettinger13936692007-04-11 18:40:58 +00002573- Request #1191699: Slices can now be pickled.
2574
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002575- Request #1193128: str.translate() now allows a None argument for
2576 translations that only remove characters without re-mapping the
2577 remaining characters.
2578
Georg Brandl5cb76c12007-03-21 09:00:39 +00002579- Patch #1682205: a TypeError while unpacking an iterable is no longer
2580 masked by a generic one with the message "unpack non-sequence".
2581
Neal Norwitzaa754b72007-03-21 06:39:48 +00002582- Remove unused file Python/fmod.c.
2583
Guido van Rossum143b5642007-03-23 04:58:42 +00002584- Bug #1683368: The object.__init__() and object.__new__() methods are
2585 now stricter in rejecting excess arguments. The only time when
2586 either allows excess arguments is when it is not overridden and the
2587 other one is. For backwards compatibility, when both are
2588 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002589 warning later). Also, type.__init__() insists on the same signature
2590 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002591
Georg Brandl3ee81df2008-05-17 18:14:43 +00002592- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2593 object to complex using its __complex__() method before falling back
2594 to the __float__() method. Therefore, the functions in the cmath
2595 module now can operate on objects that define a __complex__()
2596 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002598- Patch #1623563: allow __class__ assignment for classes with
2599 __slots__. The old and the new class are still required to have the
2600 same slot names.

2606 ``object.__reduce_ex__()`` is called with an object that is faking
2607 its type.

2613
Georg Brandl7b9c5552007-03-12 14:30:05 +00002614- Bug #1678647: write a newline after printing an exception in any
2615 case, even when converting the value to a string failed.
2616
Georg Brandl871f1bc2007-03-12 13:17:36 +00002617- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002618 its argument, if it exists. If not, it will work like before. This
2619 allows customizing the output of dir() in the presence of a
2620 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00002735- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002753 generator expressions (x for x, in ... ) works again. Fixing this
2754 problem required changing the .pyc magic number. This means that
2755 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00002794- Removed uses of dict.has_key() from distutils, and uses of

Facundo Batistad918a652007-04-24 13:54:38 +00003143- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003144 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003185 AttributeError instead of an IOError when the server's response
3186 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003220 are set for invalid interpolation sequences that would lead to

3277 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00003670 time so that opening a database previously created with the DB_DUP
3671 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3672 opens. Specifically: dictionary assignment to a DB object will
3673 replace all values for a given key when the database allows
3674 duplicate values. DB users should use DB.put(k, v) when they want
3675 to store duplicates; not DB[k] = v.

3682 characters with ASCII value less than 32. Also, it correctly quotes
3683 dots only if they occur on a single line, as opposed to the previous
3684 behavior of quoting dots if they are the second character of any
3685 line.
