Vinay Sajip6badbe92009-01-20 22:49:13 +0000481- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000482 method on file objects with closefd=False. The file descriptor is still

853What's New in Python 2.6.1
854==========================
855
856*Release date: 04-Dec-2008*
857
858Core and Builtins
859-----------------
860
861- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
862 interpreter to abort ("Fatal Python error: Could not reset the stack!")
863 instead of throwing a MemoryError.
864
865- Issue #4367: Python would segfault during compiling when the unicodedata
866 module couldn't be imported and \N escapes were present.
867
868- Issue #4348: Some bytearray methods returned that didn't cause any change to
869 the bytearray, returned the same bytearray instead of a copy.
870
871- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
872
873- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
874
875- Issue #4048: The parser module now correctly validates relative imports.
876
877- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
878 exec statement.
879
880- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
881 method does not return iterators for the 4th and 5th items.
882
883- Issue #4209: Enabling unicode_literals and the print_function in the same
884 __future__ import didn't work.
885
886- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
887 returned a path longer than MAX_PATH. (But It's doubtful this code path is
888 really executed because I cannot move to such directory on win2k)
889
890- Issue #4069: When set.remove(element) is used with a set element, the element
891 is temporarily replaced with an equivalent frozenset. But the eventual
892 KeyError would always report the empty frozenset([]) as the missing key. Now
893 it correctly refers to the initial element.
894
895- Fixed C99 style comments in several files. Python is now C89 compatible
896 again.

1023- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1024 AttributeError instead of RuntimeError, depending in which C API call
1025 exactly the recursion limit is exceeded. Consequently, both exception types
1026 are caught and silenced.

1042
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001043- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1044
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001045- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1046 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1047 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1048 ``printf`` function, whereas PyString_FromFormat has an independent
1049 implementation and uses "%zd" on all platforms for size_t values.
1050 This makes a difference on win64, where ``printf`` needs "%Id" to display
1051 64bit values.
1052
Benjamin Peterson97179b02008-09-09 20:55:01 +00001053- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1054 error.
1055
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001056- Issue #3777: long() applied to a float object now always return a long
1057 object; previously an int would be returned for small values. the __long__
1058 method is allowed to return either an int or a long, but the behaviour of
1059 float objects should not change to respect backward compatibility.
1060
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001061- Issue #3751: str.rpartition would perform a left-partition when called with
1062 a unicode argument.
1063
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001064- Issue #3683: Fix compilation when --without-threads is given.
1065
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001066- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001067 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001068 was correctly parsed but parsing of subsequent arguments failed.
1069
Vinay Sajip35e3b032008-09-01 14:33:59 +00001070- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001071 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1072 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1073 when given a tuple of classes as second argument, were looking up
1074 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1075 type object.
1076
Neal Norwitz18aa3882008-08-24 05:04:52 +00001077- Fix crashes on memory allocation failure found with failmalloc.
1078
1079- Fix memory leaks found with valgrind and update suppressions file.
1080
1081- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1082
1083- Fix problem using wrong name in decimal module reported by pychecker.
1084
Christian Heimes7d4c3172008-08-22 19:47:25 +00001085- Silenced another compiler warning about a used but not defined
1086 function 'stringlib_contains_obj'.

Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001091- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1092 library targets in the Makefile.
1093
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001094- Issue #1204: The configure script now tests for additional libraries
1095 that may be required when linking against readline. This fixes issues
1096 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1114 silent misbehaviour when a single instance is nested in multiple
1115 with statements, or when the methods are invoked in the wrong order.
1116
Vinay Sajip844f7412008-09-09 13:42:08 +00001117- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

Nick Coghland2e09382008-09-11 12:11:06 +00001119- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001120 return a list or None rather than a custom object.

1146 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1147 for catch_warnings() also led to an improvement in the raising of a
1148 DeprecationWarning related to warnings.warn_explicit().
1149
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001150- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001211What's New in Python 2.6 beta 3?
1212================================

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001215
1216Core and Builtins
1217-----------------
1218
Guido van Rossumf8402962008-08-20 15:01:50 +00001219- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1220 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1221 extensions do not automatically benefit from the class attribute
1222 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1223 to their tp_flags field if they care. This is a backwards
1224 compatibility feature; in 3.0, all types will use the cache by
1225 default.
1226
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001227- Keyword arguments can now follow starred arguments. (``f(a, *args,
1228 keyword=23)`` is now valid syntax.)
1229
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001230- ctypes function pointers that are COM methods have a boolean True
1231 value again.
1232
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001233- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1234 by denying s# to parse objects that have a releasebuffer procedure,
1235 and introducing s*.
1236
Georg Brandl1e13ea92008-08-11 09:07:59 +00001237- Issue #3537: Fix an assertion failure when an empty but presized dict
1238 object was stored in the freelist.
1239
Mark Dickinsonb6467572008-08-04 21:30:09 +00001240- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1241 ValueError consistently across platforms.
1242
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001243- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1244 (64bit Unix, for example), unichr() would truncate its argument and return
1245 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1246
Neal Norwitze7d8be82008-07-31 17:17:14 +00001247- Apply security patches from Apple.
1248
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001249- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1250 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1251
Antoine Pitrou92f82162008-07-25 22:22:08 +00001252- Issue #1819: function calls with several named parameters are now on
1253 average 35% faster (as measured by pybench).
1254
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001255- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1256 the python debugger steps into a class statement: the free variables (local
1257 variables defined in an outer scope) would be deleted from the outer scope.
1258
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001259- Issue #2620: Overflow checking when allocating or reallocating memory
1260 was not always being done properly in some python types and extension
1261 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1262 all been updated to perform better checks and places in the code that
1263 would previously leak memory on the error path when such an allocation
1264 failed have been fixed.

1270
Benjamin Petersone977ad42008-08-20 01:42:01 +00001271- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1272 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1273
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001274- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1275 version reported by these tools does not necessarily follow the python
1276 version numbering scheme, so the module is less strict when parsing it.
1277
Nick Coghlanf70385a2008-08-18 12:42:46 +00001278- Issue #2235: Added Py3k warnings for types which will become unhashable
1279 under the stricter __hash__ inheritance rules in 3.0. Several types
1280 which did not meet the rules for hash invariants and were already
1281 unhashable in 3.0 have now been explicitly flagged as unhashable in
1282 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1283 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1284
Brett Cannon88f801d2008-08-18 00:46:22 +00001285- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1286 imported into the module but exposed as part of the module's API.
1287
Brett Cannon7b96f072008-08-18 00:41:11 +00001288- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001292- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1293
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001294- Issue #3575: Incremental decoder's decode function now takes bytearray
1295 by using 's*' instead of 't#'.
1296
Jesus Cea585ad8a2009-07-02 15:37:21 +00001297- Issue #2222: Fixed reference leak when occurred os.rename()

Antoine Pitroude781a42008-08-09 12:43:23 +00001354 asking for a specific length. This problem only affected files opened

1398
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001399- Issue #643841: The language reference now provides more detailed

1411-----------------
1412
Georg Brandl3e483f62008-07-16 22:57:41 +00001413- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1414 its methods now allow for items objects that can be converted to
1415 an integer using operator.index().
1416
Mark Dickinson64b7e502008-07-16 09:40:03 +00001417- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1418 produced a ValueError instead of giving the correct float.
1419
Eric Smitha5fa5a22008-07-16 00:11:49 +00001420- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1421 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1422
Mark Dickinson7103aa42008-07-15 19:08:33 +00001423- Issue #3008: the float type has a new instance method 'float.hex'
1424 and a new class method 'float.fromhex' to convert floating-point
1425 numbers to and from hexadecimal strings, respectively.
1426
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001427- Issue #2235: __hash__ is once again inherited by default. To allow
1428 collections.Hashable to remain meaningful in the presence of the
1429 default hash implementation (object.__hash__), it is now possible
1430 to explicit block inheritance of hash by setting __hash__=None at
1431 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1432 level.
1433
Nick Coghlanb028f502008-07-13 14:52:36 +00001434- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1435 the parent module cannot be found while performing an absolute import.
1436 This means that an incorrectly defined __package__ attribute will
1437 now only prevent relative imports in that module rather than causing
1438 all imports from that module to fail.
1439
Nick Coghlan14ff9942008-07-08 14:21:42 +00001440- Issue #2517: Allow unicode messages in Exceptions again by correctly

1450 another thread's dictionary.
1451
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001452- Issue #3004: Minor change to slice.indices(): the start and stop
1453 arguments are now treated identically, making the behaviour easier
1454 to describe and understand. For example, slice(None, -10,
1455 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1456 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1457 10, -1).
1458
Georg Brandl278fc502008-07-19 12:46:12 +00001459- Issue #3219: Calling a function with repeated keyword arguments,
1460 f(a=2, a=23), would not cause a syntax error. This was a regression
1461 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001499- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1500 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001501 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001502 content-length. The problem had been corrected in the 2.4 branch, but never

1908
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001909- On MacOS X it is now possible to install the framework in 64-bit
1910 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001911 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001912
1913 This is controlled by the configure argument ``--with-universal-archs``:
1914
1915 - ``--with-universal-archs=all``: install 4-way universal
1916
1917 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1918
1919 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1920
1921 This option should be used in combination with ``--enable-universalsdk=``.
1922
1923 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 +00001973- Issue #1631171: Re-implement the 'warnings' module in C (the
1974 original Python code has been kept as backup). This will allow for
1975 using the 'warning's machinery in such places as the parser where
1976 use of pure Python code is not possible. Both the ``showarning()``
1977 and ``formatwarning()`` gain an optional 'line' argument which is
1978 not called by default for backwards-compatibility reasons. Setting
1979 ``warnings.showwarning()`` to an implementation that lacks support
1980 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002043- Issue #2550: The approach used by client/server code for obtaining
2044 ports to listen on in network-oriented tests has been refined in an
2045 effort to facilitate running multiple instances of the entire
2046 regression test suite in parallel without issue.
2047 test_support.bind_port() has been fixed such that it will always
2048 return a unique port -- which wasn't always the case with the
2049 previous implementation, especially if socket options had been set
2050 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2051 new implementation of bind_port() will actually raise an exception
2052 if it is passed an AF_INET/SOCK_STREAM socket with either the
2053 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2054 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2055 the socket it's been passed. This currently only applies to
2056 Windows. This option prevents any other sockets from binding to the
2057 host/port we've bound to, thus removing the possibility of the
2058 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2059 when a second SOCK_STREAM socket binds and accepts to a host/port
2060 that's already been bound by another socket. The optional preferred
2061 port parameter to bind_port() has been removed. Under no
2062 circumstances should tests be hard coding ports!
2063
2064 test_support.find_unused_port() has also been introduced, which will
2065 pass a temporary socket object to bind_port() in order to obtain an
2066 unused port. The temporary socket object is then closed and
2067 deleted, and the port is returned. This method should only be used
2068 for obtaining an unused port in order to pass to an external program
2069 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2070 a parameter to a server-oriented class that doesn't give you direct
2071 access to the underlying socket used.
2072
2073 Finally, test_support.HOST has been introduced, which should be used
2074 for the host argument of any relevant socket calls (i.e. bind and
2075 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002076
2077 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002078 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002079 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2080 test_asynchat and test_socket_ssl.
2081
Georg Brandl3ee81df2008-05-17 18:14:43 +00002082 It is now possible for multiple instances of the regression test
2083 suite to run in parallel without issue.

2350-----------------
2351
Fred Drakea8ee94b2008-03-01 02:45:07 +00002352- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002353 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002358
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002359- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002360 issue 215555 for a discussion.
2361
Eric Smitha73fbe72008-02-23 03:09:44 +00002362- Added the future_builtins module, which contains hex() and oct().
2363 These are the PEP 3127 version of these functions, designed to be
2364 compatible with the hex() and oct() builtins from Python 3.0. They
2365 differ slightly in their output formats from the existing, unchanged
2366 Python 2.6 builtins. The expected usage of the future_builtins
2367 module is:
2368 from future_builtins import hex, oct
2369
Eric Smith7ef40bf2008-02-20 23:34:22 +00002370- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2371 exponents for exponents with absolute value < 100. Follows C99
2372 standard. This is a change on Windows, which would use 3 digits.
2373 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2374 so that any alterations it does to the resulting string will be
2375 available in stringlib/formatter.h (for float.__format__).
2376
Eric Smith5a3c1352008-02-19 13:21:56 +00002377- Implemented PEP 3101, Advanced String Formatting. This adds a new
2378 builtin format(); a format() method for str and unicode; a
2379 __format__() method to object, str, unicode, int, long, float, and
2380 datetime; the class string.Formatter; and the C API
2381 PyObject_Format().
2382
Georg Brandl3ee81df2008-05-17 18:14:43 +00002383- Fixed several potential crashes, all caused by specially crafted
2384 __del__ methods exploiting objects in temporarily inconsistent
2385 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002387- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002388 prevent a possible crash: an Abstract Base Class would try to access
2389 a slot on a registered virtual subclass.

2392 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002393
Georg Brandl3ee81df2008-05-17 18:14:43 +00002394- Clear all free lists during a gc.collect() of the highest generation
2395 in order to allow pymalloc to free more arenas. Python may give back
2396 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002397
Georg Brandl3ee81df2008-05-17 18:14:43 +00002398- Issue #2045: Fix an infinite recursion triggered when printing a
2399 subclass of collections.defaultdict, if its default_factory is set
2400 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002401
Christian Heimesf75dbef2008-02-08 00:11:31 +00002402- Fixed a minor memory leak in dictobject.c. The content of the free
2403 list was not freed on interpreter shutdown.
2404
Georg Brandl3ee81df2008-05-17 18:14:43 +00002405- Limit free list of method and builtin function objects to 256
2406 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002407
Georg Brandl3ee81df2008-05-17 18:14:43 +00002408- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2409 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002410 to compact the internal free lists of pre-allocted ints and floats.
2411
Georg Brandl3ee81df2008-05-17 18:14:43 +00002412- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2413 calls. Python expected the return type int but the fork familie
2414 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002415
Georg Brandl3ee81df2008-05-17 18:14:43 +00002416- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2417 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002418
Georg Brandl3ee81df2008-05-17 18:14:43 +00002419- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2420 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002421
Georg Brandl3ee81df2008-05-17 18:14:43 +00002422- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2423 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002425- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2426 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002427
Georg Brandl3ee81df2008-05-17 18:14:43 +00002428- Patch #1473257: generator objects gain a gi_code attribute. This is
2429 the same object as the func_code attribute of the function that
2430 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002431
Georg Brandl3ee81df2008-05-17 18:14:43 +00002432- Issue #1920: "while 0" statements were completely removed by the
2433 compiler, even in the presence of an "else" clause, which is
2434 supposed to be run when the condition is false. Now the compiler
2435 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002436
Guido van Rossumeead05f2008-01-24 18:21:02 +00002437- A few crashers fixed: weakref_in_del.py (issue #1377858);
2438 loosing_dict_ref.py (issue #1303614, test67.py);
2439 borrowed_ref_[34].py (not in tracker).
2440
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002441- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002442 suppressed while an extension is loaded by calling SetErrorMode in
2443 dynload_win.c. The error is still reported properly.
2444
Georg Brandl3ee81df2008-05-17 18:14:43 +00002445- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002446 several extension methods and modules do not work without unicode
2447 support.
2448
Georg Brandl26543b12008-01-21 18:36:51 +00002449- Issue #1882: when compiling code from a string, encoding cookies in the
2450 second line of code were not always recognized correctly.
2451
Georg Brandl14404b62008-01-19 19:27:05 +00002452- Issue #1679: "0x" was taken as a valid integer literal.
2453
Georg Brandl6caad7d2008-01-26 14:19:22 +00002454- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002455 added.
2456
Christian Heimesc94e2b52008-01-14 04:13:37 +00002457- sys.float_info / PyFloat_GetInfo: The floating point information
2458 object was converted from a dict to a specialized structseq object.
2459
Georg Brandl3ee81df2008-05-17 18:14:43 +00002460- Patch #1816: Added sys.flags structseq. It exposes the status of
2461 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002462
Georg Brandl3ee81df2008-05-17 18:14:43 +00002463- Objects/structseq.c: Implemented new structseq representation. The
2464 patch makes structseqs (e.g. the return value of os.stat) more
2465 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002466
Georg Brandl3ee81df2008-05-17 18:14:43 +00002467- Patch #1700288: added a type attribute cache that caches method
2468 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002469
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002470- Bug #1776: __import__() no longer accepts filenames on any platform.
2471 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002472
Georg Brandlaed6c662008-01-07 17:25:53 +00002473- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2474
Georg Brandl3ee81df2008-05-17 18:14:43 +00002475- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2476 envvar and sys.dont_write_bytecode attribute. All these can be set
2477 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002478
Georg Brandl3ee81df2008-05-17 18:14:43 +00002479- Improve some exception messages when Windows fails to load an
2480 extension module. Now we get for example '%1 is not a valid Win32
2481 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002482
Georg Brandl3ee81df2008-05-17 18:14:43 +00002483- Bug #1481296: Fixed long(float('nan')) != 0L.

2486 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002487
Christian Heimes0a8143f2007-12-18 23:22:54 +00002488- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002489 and INF. float("nan"), float("inf") and float("-inf") now work on
2490 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002491
Georg Brandl3ee81df2008-05-17 18:14:43 +00002492- Compiler now generates simpler and faster code for dictionary
2493 literals. The oparg for BUILD_MAP now indicates an estimated
2494 dictionary size. There is a new opcode, STORE_MAP, for adding
2495 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002496
Georg Brandl3ee81df2008-05-17 18:14:43 +00002497- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002524- Patch #1739468: Directories and zipfiles containing a __main__.py
2525 file can now be directly executed by passing their name to the
2526 interpreter. The directory/zipfile is automatically inserted as the
2527 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002528
Georg Brandl3ee81df2008-05-17 18:14:43 +00002529- Issue #1265: Fix a problem with sys.settrace, if the tracing
2530 function uses a generator expression when at the same time the
2531 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002532
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002533- sets and frozensets now have an isdisjoint() method.
2534
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002535- optimize the performance of builtin.sum().
2536
Neal Norwitz44f326e2007-10-05 05:29:17 +00002537- Fix warnings found by the new version of the Coverity checker.
2538
Georg Brandl3ee81df2008-05-17 18:14:43 +00002539- The enumerate() builtin function is no longer bounded to sequences
2540 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2541 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002542
Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Issue #1686386: Tuple's tp_repr did not take into account the
2544 possibility of having a self-referential tuple, which is possible
2545 from C code. Nor did object's tp_str consider that a type's tp_str
2546 could do something that could lead to an inifinite recursion.
2547 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2548 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002549
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Issue #1164: It was possible to trigger deadlock when using the
2551 'print' statement to write to a file since the GIL was not released
2552 as needed. Now PyObject_Print() does the right thing along with
2553 various tp_print implementations of the built-in types and those in
2554 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002555
Georg Brandl3ee81df2008-05-17 18:14:43 +00002556- Issue #1147: Exceptions were directly allowing string exceptions in
2557 their throw() method even though string exceptions no longer
2558 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002559
Georg Brandl3ee81df2008-05-17 18:14:43 +00002560- Issue #1096: Prevent a segfault from getting the repr of a very
2561 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002562
Brett Cannon1e534b52007-09-07 04:18:30 +00002563- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002564 PyObject_Call() never calling back out to Python code to trigger
2565 recursion depth updates/checks. Required the creation of a static
2566 RuntimeError instance in case normalizing an exception put the
2567 recursion check value past its limit. Fixes crashers
2568 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002569

Neal Norwitz0ac60192007-05-27 04:08:54 +00002583- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002584 __*__ attributes. (Some already existed, e.g., __doc__ and
2585 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002586
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002587- Add -3 option to the interpreter to warn about features that are
2588 deprecated and will be changed/removed in Python 3.0.
2589
Georg Brandl2134e752007-05-21 20:34:16 +00002590- Patch #1686487: you can now pass any mapping after '**' in function
2591 calls.
2592
Collin Winter62903052007-05-18 23:11:24 +00002593- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002594 "except E as target:". This is to provide forwards compatibility
2595 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00002597- Deprecate BaseException.message as per PEP 352.
2598
Georg Brandl3ee81df2008-05-17 18:14:43 +00002599- Issue #1303614: don't expose object's __dict__ when the dict is

2601
Vinay Sajip8549ce32007-05-06 17:53:37 +00002602- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002603 setting a plain string, ie don't expand to single letter identifiers.
2604
Raymond Hettinger13936692007-04-11 18:40:58 +00002605- Request #1191699: Slices can now be pickled.
2606
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002607- Request #1193128: str.translate() now allows a None argument for
2608 translations that only remove characters without re-mapping the
2609 remaining characters.
2610
Georg Brandl5cb76c12007-03-21 09:00:39 +00002611- Patch #1682205: a TypeError while unpacking an iterable is no longer
2612 masked by a generic one with the message "unpack non-sequence".
2613
Neal Norwitzaa754b72007-03-21 06:39:48 +00002614- Remove unused file Python/fmod.c.
2615
Guido van Rossum143b5642007-03-23 04:58:42 +00002616- Bug #1683368: The object.__init__() and object.__new__() methods are
2617 now stricter in rejecting excess arguments. The only time when
2618 either allows excess arguments is when it is not overridden and the
2619 other one is. For backwards compatibility, when both are
2620 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002621 warning later). Also, type.__init__() insists on the same signature
2622 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002623
Georg Brandl3ee81df2008-05-17 18:14:43 +00002624- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2625 object to complex using its __complex__() method before falling back
2626 to the __float__() method. Therefore, the functions in the cmath
2627 module now can operate on objects that define a __complex__()
2628 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002629
Georg Brandl3ee81df2008-05-17 18:14:43 +00002630- Patch #1623563: allow __class__ assignment for classes with
2631 __slots__. The old and the new class are still required to have the

Georg Brandl3ee81df2008-05-17 18:14:43 +00003702 time so that opening a database previously created with the DB_DUP
3703 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3704 opens. Specifically: dictionary assignment to a DB object will
3705 replace all values for a given key when the database allows
3706 duplicate values. DB users should use DB.put(k, v) when they want
3707 to store duplicates; not DB[k] = v.

3714 characters with ASCII value less than 32. Also, it correctly quotes
3715 dots only if they occur on a single line, as opposed to the previous
3716 behavior of quoting dots if they are the second character of any
3717 line.
