596What's New in Python 2.6.1
597==========================
598
599*Release date: 04-Dec-2008*
600
601Core and Builtins
602-----------------
603
604- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
605 interpreter to abort ("Fatal Python error: Could not reset the stack!")
606 instead of throwing a MemoryError.
607
608- Issue #4367: Python would segfault during compiling when the unicodedata
609 module couldn't be imported and \N escapes were present.
610
611- Issue #4348: Some bytearray methods returned that didn't cause any change to
612 the bytearray, returned the same bytearray instead of a copy.
613
614- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
615
616- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
617
618- Issue #4048: The parser module now correctly validates relative imports.
619
620- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
621 exec statement.
622
623- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
624 method does not return iterators for the 4th and 5th items.
625
626- Issue #4209: Enabling unicode_literals and the print_function in the same
627 __future__ import didn't work.
628
629- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
630 returned a path longer than MAX_PATH. (But It's doubtful this code path is
631 really executed because I cannot move to such directory on win2k)
632
633- Issue #4069: When set.remove(element) is used with a set element, the element
634 is temporarily replaced with an equivalent frozenset. But the eventual
635 KeyError would always report the empty frozenset([]) as the missing key. Now
636 it correctly refers to the initial element.
637
638- Fixed C99 style comments in several files. Python is now C89 compatible
639 again.

787
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000788- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
789 PyString_FromFormat or PyErr_Format to display size_t values. The macro
790 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
791 ``printf`` function, whereas PyString_FromFormat has an independent
792 implementation and uses "%zd" on all platforms for size_t values.
793 This makes a difference on win64, where ``printf`` needs "%Id" to display
794 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +0000796- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

800 object; previously an int would be returned for small values. the __long__
801 method is allowed to return either an int or a long, but the behaviour of
802 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000804- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +0000810 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000811 was correctly parsed but parsing of subsequent arguments failed.
812
Vinay Sajip35e3b032008-09-01 14:33:59 +0000813- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000814 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
815 mechanism. In the process, fix a bug where isinstance() and issubclass(),
816 when given a tuple of classes as second argument, were looking up
817 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
818 type object.
819
Neal Norwitz18aa3882008-08-24 05:04:52 +0000820- Fix crashes on memory allocation failure found with failmalloc.

829 function 'stringlib_contains_obj'.

961
Guido van Rossumf8402962008-08-20 15:01:50 +0000962- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
963 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
964 extensions do not automatically benefit from the class attribute
965 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
966 to their tp_flags field if they care. This is a backwards
967 compatibility feature; in 3.0, all types will use the cache by
968 default.
969
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000970- Keyword arguments can now follow starred arguments. (``f(a, *args,

Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000986- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
987 (64bit Unix, for example), unichr() would truncate its argument and return
988 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
989
Neal Norwitze7d8be82008-07-31 17:17:14 +0000990- Apply security patches from Apple.
991
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000992- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
993 PyErr_ExceptionMatches returns 0 when an exception occurs there.
994
Antoine Pitrou92f82162008-07-25 22:22:08 +0000995- Issue #1819: function calls with several named parameters are now on
996 average 35% faster (as measured by pybench).
997
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000998- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
999 the python debugger steps into a class statement: the free variables (local
1000 variables defined in an outer scope) would be deleted from the outer scope.
1001
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001002- Issue #2620: Overflow checking when allocating or reallocating memory
1003 was not always being done properly in some python types and extension
1004 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1005 all been updated to perform better checks and places in the code that
1006 would previously leak memory on the error path when such an allocation
1007 failed have been fixed.

1016
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001017- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1018 version reported by these tools does not necessarily follow the python
1019 version numbering scheme, so the module is less strict when parsing it.
1020
Nick Coghlanf70385a2008-08-18 12:42:46 +00001021- Issue #2235: Added Py3k warnings for types which will become unhashable
1022 under the stricter __hash__ inheritance rules in 3.0. Several types
1023 which did not meet the rules for hash invariants and were already
1024 unhashable in 3.0 have now been explicitly flagged as unhashable in
1025 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1026 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1027
Brett Cannon88f801d2008-08-18 00:46:22 +00001028- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1053 pathological input because of quadratic or exponential behaviour of a
1054 regular expression.
1055

1057 thread-safe.
1058
Brett Cannonbf3157b2008-08-14 05:00:03 +00001059- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1060 since mimetools itself is deprecated. Because modules are cached, all
1061 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1062
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001063- Issue #3134: shutil referenced undefined WindowsError symbol.

1069 version that did not raise a DeprecationWarning under -3.
1070
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001071- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1072 a MemoryError rather than silently stop the iteration.
1073

1075 to _sre.compile() will now be rejected. This should not affect anybody
1076 since the re.compile() function never generates invalid re-bytecode.

Skip Montanaroa032bf42008-08-08 22:52:51 +00001078- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1079 upon first access it can be automatically initialized from the csv file if
1080 it wasn't initialized during instantiation.
1081
Brett Cannon3aa2a492008-08-06 22:28:09 +00001082- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1083 the reload() built-in has been removed.
1084
Brett Cannon7e30b672008-08-04 21:52:25 +00001085- Changed code in the following modules/packages to remove warnings raised

1094 raised an AttributeError.
1095
Benjamin Peterson01a24322008-07-28 23:35:27 +00001096- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001097 asking for a specific length. This problem only affected files opened
1098 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001099

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001123- Issue #3394: zipfile.writestr sets external attributes when passed a
1124 file name rather than a ZipInfo instance, so files are extracted with
1125 mode 0600 rather than 000 under Unix.
1126
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001127- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1128 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001139- Issue #2235: the C API function PyObject_HashNotImplemented and its
1140 interaction with the tp_hash slot (added in 2.6b2) are now documented
1141
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001142- Issue #643841: The language reference now provides more detailed
1143 coverage of the lookup process for special methods. The disclaimers
1144 regarding lack of coverage of new-style classes have also been
1145 removed, since the coverage is now fairly reasonable.

1149================================
1150
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001151*Release date: 17-Jul-2008*
1152
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001153Core and Builtins
1154-----------------
1155
Georg Brandl3e483f62008-07-16 22:57:41 +00001156- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1157 its methods now allow for items objects that can be converted to
1158 an integer using operator.index().
1159
Mark Dickinson64b7e502008-07-16 09:40:03 +00001160- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1161 produced a ValueError instead of giving the correct float.
1162
Eric Smitha5fa5a22008-07-16 00:11:49 +00001163- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1164 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1165
Mark Dickinson7103aa42008-07-15 19:08:33 +00001166- Issue #3008: the float type has a new instance method 'float.hex'
1167 and a new class method 'float.fromhex' to convert floating-point
1168 numbers to and from hexadecimal strings, respectively.
1169
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001170- Issue #2235: __hash__ is once again inherited by default. To allow
1171 collections.Hashable to remain meaningful in the presence of the
1172 default hash implementation (object.__hash__), it is now possible
1173 to explicit block inheritance of hash by setting __hash__=None at
1174 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1175 level.
1176
Nick Coghlanb028f502008-07-13 14:52:36 +00001177- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1178 the parent module cannot be found while performing an absolute import.
1179 This means that an incorrectly defined __package__ attribute will
1180 now only prevent relative imports in that module rather than causing
1181 all imports from that module to fail.
1182
Nick Coghlan14ff9942008-07-08 14:21:42 +00001183- Issue #2517: Allow unicode messages in Exceptions again by correctly
1184 bypassing the instance dictionary when looking up __unicode__ on
1185 new-style classes.
1186
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001187- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1188 set to a custom object whose write() method happens to install
1189 another file in sys.stdout.
1190
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001191- Issue #3088: Corrected a race condition in classes derived from
1192 threading.local: the first member set by a thread could be saved in
1193 another thread's dictionary.
1194
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001195- Issue #3004: Minor change to slice.indices(): the start and stop
1196 arguments are now treated identically, making the behaviour easier
1197 to describe and understand. For example, slice(None, -10,
1198 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1199 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1200 10, -1).
1201
Georg Brandl278fc502008-07-19 12:46:12 +00001202- Issue #3219: Calling a function with repeated keyword arguments,
1203 f(a=2, a=23), would not cause a syntax error. This was a regression
1204 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001205
Georg Brandl278fc502008-07-19 12:46:12 +00001206- Issue #2862: Make int and float freelist management consistent with
1207 other freelists. Changes their CompactFreeList apis into
1208 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001213- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1214 api functions without holding the GIL, which could lead to a fatal
1215 error when they failed.
1216
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001217- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1226 ForkingPickler.register() to resolve conflict with ctypes.
1227
Vinay Sajip51e65192008-07-18 09:01:10 +00001228- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00001230- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1231 a valid dlerror() message.
1232
Thomas Heller2bad6572008-07-15 17:19:50 +00001233- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1234 incomplete structure was created.
1235

1239
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001240- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001241
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001242- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1243 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001244 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001245 content-length. The problem had been corrected in the 2.4 branch, but never
1246 merged into trunk.
1247
Georg Brandle78fbcc2008-07-05 10:13:36 +00001248- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001261- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1262 handling is now the same as that of other special attributes like __name__).
1263
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001264- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1265 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00001654 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001655
1656 This is controlled by the configure argument ``--with-universal-archs``:
1657
1658 - ``--with-universal-archs=all``: install 4-way universal
1659
1660 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1661
1662 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1663
1664 This option should be used in combination with ``--enable-universalsdk=``.
1665
1666 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 +00001716- Issue #1631171: Re-implement the 'warnings' module in C (the
1717 original Python code has been kept as backup). This will allow for
1718 using the 'warning's machinery in such places as the parser where
1719 use of pure Python code is not possible. Both the ``showarning()``
1720 and ``formatwarning()`` gain an optional 'line' argument which is
1721 not called by default for backwards-compatibility reasons. Setting
1722 ``warnings.showwarning()`` to an implementation that lacks support
1723 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001786- Issue #2550: The approach used by client/server code for obtaining
1787 ports to listen on in network-oriented tests has been refined in an
1788 effort to facilitate running multiple instances of the entire
1789 regression test suite in parallel without issue.
1790 test_support.bind_port() has been fixed such that it will always
1791 return a unique port -- which wasn't always the case with the
1792 previous implementation, especially if socket options had been set
1793 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1794 new implementation of bind_port() will actually raise an exception
1795 if it is passed an AF_INET/SOCK_STREAM socket with either the
1796 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1797 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1798 the socket it's been passed. This currently only applies to
1799 Windows. This option prevents any other sockets from binding to the
1800 host/port we've bound to, thus removing the possibility of the
1801 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1802 when a second SOCK_STREAM socket binds and accepts to a host/port
1803 that's already been bound by another socket. The optional preferred
1804 port parameter to bind_port() has been removed. Under no
1805 circumstances should tests be hard coding ports!
1806
1807 test_support.find_unused_port() has also been introduced, which will
1808 pass a temporary socket object to bind_port() in order to obtain an
1809 unused port. The temporary socket object is then closed and
1810 deleted, and the port is returned. This method should only be used
1811 for obtaining an unused port in order to pass to an external program
1812 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1813 a parameter to a server-oriented class that doesn't give you direct
1814 access to the underlying socket used.
1815
1816 Finally, test_support.HOST has been introduced, which should be used
1817 for the host argument of any relevant socket calls (i.e. bind and
1818 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001819
1820 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001821 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

1823 test_asynchat and test_socket_ssl.
1824
Georg Brandl3ee81df2008-05-17 18:14:43 +00001825 It is now possible for multiple instances of the regression test
1826 suite to run in parallel without issue.

2092Core and builtins
2093-----------------
2094
Fred Drakea8ee94b2008-03-01 02:45:07 +00002095- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002096 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002097
Georg Brandlad61bc82008-02-23 15:11:18 +00002098- Issue #2067: file.__exit__() now calls subclasses' close() method.
2099
2100- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002101
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002102- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002103 issue 215555 for a discussion.
2104
Eric Smitha73fbe72008-02-23 03:09:44 +00002105- Added the future_builtins module, which contains hex() and oct().
2106 These are the PEP 3127 version of these functions, designed to be
2107 compatible with the hex() and oct() builtins from Python 3.0. They
2108 differ slightly in their output formats from the existing, unchanged
2109 Python 2.6 builtins. The expected usage of the future_builtins
2110 module is:
2111 from future_builtins import hex, oct
2112
Eric Smith7ef40bf2008-02-20 23:34:22 +00002113- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2114 exponents for exponents with absolute value < 100. Follows C99
2115 standard. This is a change on Windows, which would use 3 digits.
2116 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2117 so that any alterations it does to the resulting string will be
2118 available in stringlib/formatter.h (for float.__format__).
2119
Eric Smith5a3c1352008-02-19 13:21:56 +00002120- Implemented PEP 3101, Advanced String Formatting. This adds a new
2121 builtin format(); a format() method for str and unicode; a
2122 __format__() method to object, str, unicode, int, long, float, and
2123 datetime; the class string.Formatter; and the C API
2124 PyObject_Format().
2125
Georg Brandl3ee81df2008-05-17 18:14:43 +00002126- Fixed several potential crashes, all caused by specially crafted
2127 __del__ methods exploiting objects in temporarily inconsistent
2128 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002129
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002130- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002131 prevent a possible crash: an Abstract Base Class would try to access
2132 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002133
Georg Brandl3ee81df2008-05-17 18:14:43 +00002134- Fixed repr() and str() of complex numbers with infinity or nan as
2135 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002136
Georg Brandl3ee81df2008-05-17 18:14:43 +00002137- Clear all free lists during a gc.collect() of the highest generation
2138 in order to allow pymalloc to free more arenas. Python may give back
2139 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002140
Georg Brandl3ee81df2008-05-17 18:14:43 +00002141- Issue #2045: Fix an infinite recursion triggered when printing a
2142 subclass of collections.defaultdict, if its default_factory is set
2143 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002144
Christian Heimesf75dbef2008-02-08 00:11:31 +00002145- Fixed a minor memory leak in dictobject.c. The content of the free
2146 list was not freed on interpreter shutdown.
2147
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148- Limit free list of method and builtin function objects to 256
2149 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002150
Georg Brandl3ee81df2008-05-17 18:14:43 +00002151- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2152 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002153 to compact the internal free lists of pre-allocted ints and floats.
2154
Georg Brandl3ee81df2008-05-17 18:14:43 +00002155- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2156 calls. Python expected the return type int but the fork familie
2157 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002158
Georg Brandl3ee81df2008-05-17 18:14:43 +00002159- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2160 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002161
Georg Brandl3ee81df2008-05-17 18:14:43 +00002162- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2163 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002164
Georg Brandl3ee81df2008-05-17 18:14:43 +00002165- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2166 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002167
Georg Brandl3ee81df2008-05-17 18:14:43 +00002168- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2169 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002170
Georg Brandl3ee81df2008-05-17 18:14:43 +00002171- Patch #1473257: generator objects gain a gi_code attribute. This is
2172 the same object as the func_code attribute of the function that
2173 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002174
Georg Brandl3ee81df2008-05-17 18:14:43 +00002175- Issue #1920: "while 0" statements were completely removed by the
2176 compiler, even in the presence of an "else" clause, which is
2177 supposed to be run when the condition is false. Now the compiler
2178 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002179
Guido van Rossumeead05f2008-01-24 18:21:02 +00002180- A few crashers fixed: weakref_in_del.py (issue #1377858);
2181 loosing_dict_ref.py (issue #1303614, test67.py);
2182 borrowed_ref_[34].py (not in tracker).
2183
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002184- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002185 suppressed while an extension is loaded by calling SetErrorMode in
2186 dynload_win.c. The error is still reported properly.
2187
Georg Brandl3ee81df2008-05-17 18:14:43 +00002188- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002189 several extension methods and modules do not work without unicode
2190 support.
2191
Georg Brandl26543b12008-01-21 18:36:51 +00002192- Issue #1882: when compiling code from a string, encoding cookies in the
2193 second line of code were not always recognized correctly.
2194
Georg Brandl14404b62008-01-19 19:27:05 +00002195- Issue #1679: "0x" was taken as a valid integer literal.
2196
Georg Brandl6caad7d2008-01-26 14:19:22 +00002197- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002198 added.
2199
Christian Heimesc94e2b52008-01-14 04:13:37 +00002200- sys.float_info / PyFloat_GetInfo: The floating point information
2201 object was converted from a dict to a specialized structseq object.
2202
Georg Brandl3ee81df2008-05-17 18:14:43 +00002203- Patch #1816: Added sys.flags structseq. It exposes the status of
2204 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002205
Georg Brandl3ee81df2008-05-17 18:14:43 +00002206- Objects/structseq.c: Implemented new structseq representation. The
2207 patch makes structseqs (e.g. the return value of os.stat) more
2208 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002209
Georg Brandl3ee81df2008-05-17 18:14:43 +00002210- Patch #1700288: added a type attribute cache that caches method
2211 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002212
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002213- Bug #1776: __import__() no longer accepts filenames on any platform.
2214 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002215
Georg Brandlaed6c662008-01-07 17:25:53 +00002216- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2217
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2219 envvar and sys.dont_write_bytecode attribute. All these can be set
2220 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002221
Georg Brandl3ee81df2008-05-17 18:14:43 +00002222- Improve some exception messages when Windows fails to load an
2223 extension module. Now we get for example '%1 is not a valid Win32
2224 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002225
Georg Brandl3ee81df2008-05-17 18:14:43 +00002226- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002228- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2229 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002230
Christian Heimes0a8143f2007-12-18 23:22:54 +00002231- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002232 and INF. float("nan"), float("inf") and float("-inf") now work on
2233 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002234
Georg Brandl3ee81df2008-05-17 18:14:43 +00002235- Compiler now generates simpler and faster code for dictionary
2236 literals. The oparg for BUILD_MAP now indicates an estimated
2237 dictionary size. There is a new opcode, STORE_MAP, for adding
2238 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002239
Georg Brandl3ee81df2008-05-17 18:14:43 +00002240- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002242- Issue #1620: New property decorator syntax was modifying the
2243 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002244
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- Issue #1538: Avoid copying string in split/rsplit if the split char
2246 is not found.

2253 __package__ attribute.
2254
Georg Brandl3ee81df2008-05-17 18:14:43 +00002255- Issue #1402: Fix a crash on exit, when another thread is still
2256 running, and if the deallocation of its frames somehow calls the
2257 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002258

2268 file can now be directly executed by passing their name to the
2269 interpreter. The directory/zipfile is automatically inserted as the
2270 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002271
Georg Brandl3ee81df2008-05-17 18:14:43 +00002272- Issue #1265: Fix a problem with sys.settrace, if the tracing
2273 function uses a generator expression when at the same time the
2274 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002275
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002276- sets and frozensets now have an isdisjoint() method.
2277
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002278- optimize the performance of builtin.sum().
2279
Neal Norwitz44f326e2007-10-05 05:29:17 +00002280- Fix warnings found by the new version of the Coverity checker.
2281
Georg Brandl3ee81df2008-05-17 18:14:43 +00002282- The enumerate() builtin function is no longer bounded to sequences
2283 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2284 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002285
Georg Brandl3ee81df2008-05-17 18:14:43 +00002286- Issue #1686386: Tuple's tp_repr did not take into account the
2287 possibility of having a self-referential tuple, which is possible
2288 from C code. Nor did object's tp_str consider that a type's tp_str
2289 could do something that could lead to an inifinite recursion.
2290 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2291 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002292
Georg Brandl3ee81df2008-05-17 18:14:43 +00002293- Issue #1164: It was possible to trigger deadlock when using the
2294 'print' statement to write to a file since the GIL was not released
2295 as needed. Now PyObject_Print() does the right thing along with
2296 various tp_print implementations of the built-in types and those in
2297 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002298
Georg Brandl3ee81df2008-05-17 18:14:43 +00002299- Issue #1147: Exceptions were directly allowing string exceptions in
2300 their throw() method even though string exceptions no longer
2301 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002302
Georg Brandl3ee81df2008-05-17 18:14:43 +00002303- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002306- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002307 PyObject_Call() never calling back out to Python code to trigger
2308 recursion depth updates/checks. Required the creation of a static
2309 RuntimeError instance in case normalizing an exception put the
2310 recursion check value past its limit. Fixes crashers
2311 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002312
Georg Brandl3ee81df2008-05-17 18:14:43 +00002313- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002326- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002327 __*__ attributes. (Some already existed, e.g., __doc__ and
2328 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002329
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002330- Add -3 option to the interpreter to warn about features that are
2331 deprecated and will be changed/removed in Python 3.0.
2332
Georg Brandl2134e752007-05-21 20:34:16 +00002333- Patch #1686487: you can now pass any mapping after '**' in function
2334 calls.
2335
Collin Winter62903052007-05-18 23:11:24 +00002336- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002337 "except E as target:". This is to provide forwards compatibility
2338 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002339
Brett Cannon229cee22007-05-05 01:34:02 +00002340- Deprecate BaseException.message as per PEP 352.
2341
Georg Brandl3ee81df2008-05-17 18:14:43 +00002342- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002343 inherited from a builtin base.
2344
Vinay Sajip8549ce32007-05-06 17:53:37 +00002345- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002346 setting a plain string, ie don't expand to single letter identifiers.
2347
Raymond Hettinger13936692007-04-11 18:40:58 +00002348- Request #1191699: Slices can now be pickled.
2349
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002350- Request #1193128: str.translate() now allows a None argument for
2351 translations that only remove characters without re-mapping the
2352 remaining characters.
2353
Georg Brandl5cb76c12007-03-21 09:00:39 +00002354- Patch #1682205: a TypeError while unpacking an iterable is no longer
2355 masked by a generic one with the message "unpack non-sequence".
2356
Neal Norwitzaa754b72007-03-21 06:39:48 +00002357- Remove unused file Python/fmod.c.
2358
Guido van Rossum143b5642007-03-23 04:58:42 +00002359- Bug #1683368: The object.__init__() and object.__new__() methods are
2360 now stricter in rejecting excess arguments. The only time when
2361 either allows excess arguments is when it is not overridden and the
2362 other one is. For backwards compatibility, when both are
2363 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002364 warning later). Also, type.__init__() insists on the same signature
2365 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002366
Georg Brandl3ee81df2008-05-17 18:14:43 +00002367- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2368 object to complex using its __complex__() method before falling back
2369 to the __float__() method. Therefore, the functions in the cmath
2370 module now can operate on objects that define a __complex__()
2371 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002372
Georg Brandl3ee81df2008-05-17 18:14:43 +00002373- Patch #1623563: allow __class__ assignment for classes with
2374 __slots__. The old and the new class are still required to have the
2375 same slot names.

2388
Georg Brandl7b9c5552007-03-12 14:30:05 +00002389- Bug #1678647: write a newline after printing an exception in any
2390 case, even when converting the value to a string failed.
2391
Georg Brandl871f1bc2007-03-12 13:17:36 +00002392- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002393 its argument, if it exists. If not, it will work like before. This
2394 allows customizing the output of dir() in the presence of a
2395 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002396
Collin Winter276887b2007-03-12 16:11:39 +00002397- Patch #922167: Python no longer segfaults when faced with infinitely
2398 self-recursive reload() calls (as reported by bug #742342).
2399
Georg Brandl3ee81df2008-05-17 18:14:43 +00002400- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002403- Patch #1491866: change the complex() constructor to allow
2404 parthensized forms. This means complex(repr(x)) now works instead of
2405 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002406
Georg Brandlaa2321b2007-03-07 00:40:28 +00002407- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002408 makes the filenames the warning module prints much more sensible
2409 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002410
Georg Brandl49aafc92007-03-07 00:34:46 +00002411- Variant of patch #697613: don't exit the interpreter on a SystemExit
2412 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002413 variable is given, but break into the interactive interpreter just
2414 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002419- Bug #1674503: close the file opened by execfile() in an error
2420 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002421
Georg Brandl0fca97a2007-03-05 22:28:08 +00002422- Patch #1674228: when assigning a slice (old-style), check for the
2423 sq_ass_slice instead of the sq_slice slot.
2424
Georg Brandl3ee81df2008-05-17 18:14:43 +00002425- When printing an unraisable error, don't print exceptions. before
2426 the name. This duplicates the behavior whening normally printing
2427 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002428
Georg Brandl3ee81df2008-05-17 18:14:43 +00002429- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- Bug #1377858: Fix the segfaulting of the interpreter when an object
2436 created a weakref on itself during a __del__ call for new-style
2437 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002960 AttributeError instead of an IOError when the server's response
2961 didn't contain a valid HTTP status line.

2993
Georg Brandl92a6bae2007-03-13 17:43:32 +00002994- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002995 are set for invalid interpolation sequences that would lead to

3052 TestCase and TestSuite subclasses (not instances) are no longer
3053 accepted in TestSuite.addTest(). This should cause no

3055 -- the failure just occurred later, with a more cumbersome
3056 exception.

3335 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003336
Georg Brandl3ee81df2008-05-17 18:14:43 +00003337- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3338 with RFC 3207 and forgets any knowledge obtained from the server not
3339 obtained from the TLS negotiation itself. Patch contributed by Bill
3340 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003341
Georg Brandl3ee81df2008-05-17 18:14:43 +00003342- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003343 that the SMTP.starttls() caller no longer needs to call ehlo()
3344 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003345 does not claim to support starttls. Adds the
3346 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3427 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3428 silently miscode subclasses of those types. Now, it raises a
3429 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003430

Georg Brandl3ee81df2008-05-17 18:14:43 +00003445 time so that opening a database previously created with the DB_DUP
3446 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3447 opens. Specifically: dictionary assignment to a DB object will
3448 replace all values for a given key when the database allows
3449 duplicate values. DB users should use DB.put(k, v) when they want
3450 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003451

3457 characters with ASCII value less than 32. Also, it correctly quotes
3458 dots only if they occur on a single line, as opposed to the previous
3459 behavior of quoting dots if they are the second character of any
3460 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003461

3798 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003799
3800- Patch #1720595: add T_BOOL to the range of structmember types.
3801
3802- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3803 ``PyFloat_GetInfo()`` to the float API.
3804
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3806 of w# format code incorrectly truncated the length to an int, even
3807 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3808 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003809
Georg Brandl3ee81df2008-05-17 18:14:43 +00003810- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3811 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003813- PEP 3123: Provide forward compatibility with Python 3.0, while
3814 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3815 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003816
Georg Brandl3ee81df2008-05-17 18:14:43 +00003817- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3818 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003819
3820- Patch #1733960: Allow T_LONGLONG to accept ints.
3821
3822- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3823
Christian Heimes000a0742008-01-03 22:16:32 +00003824- Added a new API function ``PyImport_ImportModuleNoBlock``.
3825
Georg Brandl6caad7d2008-01-26 14:19:22 +00003826- Bug #1637022: Prefix AST symbols with _Py_.
3827
3828- Fix some leftovers from the conversion from int to Py_ssize_t
3829 (relevant to strings and sequences of more than 2**31 items).
3830
3831- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3832 outside of pystate.c and should not be necessary.
3833
Georg Brandl3ee81df2008-05-17 18:14:43 +00003834- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3835 absolute imports. In earlier versions they might have used relative
3836 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003837
Georg Brandl3ee81df2008-05-17 18:14:43 +00003838- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3839 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003840
Georg Brandl3ee81df2008-05-17 18:14:43 +00003841- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3842 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003848- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3849 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3850 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3851 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003866- Removed the macfs module. It had been deprecated since Python 2.5.
3867 This lead to the deprecation of macostools.touched() as it relied
3868 solely on macfs and was a no-op under OS X.
