315 forever on incomplete input. That caused tarfile.open() to hang when used
316 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
317 partial bzip2 compressed data.
318

409 do an explicit seek to the end of file (so that e.g. tell() returns the
410 file size rather than 0). This is consistent with the behaviour of the
411 traditional 2.x file object.

446 302 conformant loader) will now work correctly in most cases (they
447 are still subject to the constraints that exist for all code running
448 from inside a module loaded via a PEP 302 loader and attempting to

607What's New in Python 2.6.1
608==========================
609
610*Release date: 04-Dec-2008*
611
612Core and Builtins
613-----------------
614
615- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
616 interpreter to abort ("Fatal Python error: Could not reset the stack!")
617 instead of throwing a MemoryError.
618
619- Issue #4367: Python would segfault during compiling when the unicodedata
620 module couldn't be imported and \N escapes were present.
621
622- Issue #4348: Some bytearray methods returned that didn't cause any change to
623 the bytearray, returned the same bytearray instead of a copy.
624
625- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
626
627- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
628
629- Issue #4048: The parser module now correctly validates relative imports.
630
631- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
632 exec statement.
633
634- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
635 method does not return iterators for the 4th and 5th items.
636
637- Issue #4209: Enabling unicode_literals and the print_function in the same
638 __future__ import didn't work.
639
640- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
641 returned a path longer than MAX_PATH. (But It's doubtful this code path is
642 really executed because I cannot move to such directory on win2k)
643
644- Issue #4069: When set.remove(element) is used with a set element, the element
645 is temporarily replaced with an equivalent frozenset. But the eventual
646 KeyError would always report the empty frozenset([]) as the missing key. Now
647 it correctly refers to the initial element.
648
649- Fixed C99 style comments in several files. Python is now C89 compatible
650 again.
651
652Library

798
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000799- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
800 PyString_FromFormat or PyErr_Format to display size_t values. The macro
801 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
802 ``printf`` function, whereas PyString_FromFormat has an independent
803 implementation and uses "%zd" on all platforms for size_t values.
804 This makes a difference on win64, where ``printf`` needs "%Id" to display
805 64bit values.

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

Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000822 was correctly parsed but parsing of subsequent arguments failed.
823
Vinay Sajip35e3b032008-09-01 14:33:59 +0000824- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000825 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
826 mechanism. In the process, fix a bug where isinstance() and issubclass(),
827 when given a tuple of classes as second argument, were looking up
828 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
829 type object.

971-----------------
972
Guido van Rossumf8402962008-08-20 15:01:50 +0000973- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
974 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
975 extensions do not automatically benefit from the class attribute
976 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
977 to their tp_flags field if they care. This is a backwards
978 compatibility feature; in 3.0, all types will use the cache by
979 default.
980
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000981- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +0000994- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
995 ValueError consistently across platforms.
996
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000997- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
998 (64bit Unix, for example), unichr() would truncate its argument and return
999 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00001001- Apply security patches from Apple.
1002
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001003- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1004 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1005
Antoine Pitrou92f82162008-07-25 22:22:08 +00001006- Issue #1819: function calls with several named parameters are now on
1007 average 35% faster (as measured by pybench).
1008
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001009- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1010 the python debugger steps into a class statement: the free variables (local
1011 variables defined in an outer scope) would be deleted from the outer scope.
1012
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001013- Issue #2620: Overflow checking when allocating or reallocating memory
1014 was not always being done properly in some python types and extension
1015 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1016 all been updated to perform better checks and places in the code that
1017 would previously leak memory on the error path when such an allocation
1018 failed have been fixed.

1027
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001028- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1029 version reported by these tools does not necessarily follow the python
1030 version numbering scheme, so the module is less strict when parsing it.
1031
Nick Coghlanf70385a2008-08-18 12:42:46 +00001032- Issue #2235: Added Py3k warnings for types which will become unhashable
1033 under the stricter __hash__ inheritance rules in 3.0. Several types
1034 which did not meet the rules for hash invariants and were already
1035 unhashable in 3.0 have now been explicitly flagged as unhashable in
1036 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1037 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1038

1062
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001063- Issue #2676: in the email package, content-type parsing was hanging on
1064 pathological input because of quadratic or exponential behaviour of a
1065 regular expression.
1066
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001067- Issue #3476: binary buffered reading through the new "io" library is now
1068 thread-safe.
1069
Brett Cannonbf3157b2008-08-14 05:00:03 +00001070- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1071 since mimetools itself is deprecated. Because modules are cached, all
1072 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1073
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001074- Issue #3134: shutil referenced undefined WindowsError symbol.

1080 version that did not raise a DeprecationWarning under -3.
1081
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001082- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1083 a MemoryError rather than silently stop the iteration.
1084
Guido van Rossum59ce9012008-08-09 14:55:34 +00001085- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1086 to _sre.compile() will now be rejected. This should not affect anybody
1087 since the re.compile() function never generates invalid re-bytecode.
1088
Skip Montanaroa032bf42008-08-08 22:52:51 +00001089- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1090 upon first access it can be automatically initialized from the csv file if
1091 it wasn't initialized during instantiation.
1092
Brett Cannon3aa2a492008-08-06 22:28:09 +00001093- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1094 the reload() built-in has been removed.
1095
Brett Cannon7e30b672008-08-04 21:52:25 +00001096- Changed code in the following modules/packages to remove warnings raised

1105 raised an AttributeError.
1106
Benjamin Peterson01a24322008-07-28 23:35:27 +00001107- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001108 asking for a specific length. This problem only affected files opened
1109 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001110

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001134- Issue #3394: zipfile.writestr sets external attributes when passed a
1135 file name rather than a ZipInfo instance, so files are extracted with
1136 mode 0600 rather than 000 under Unix.
1137
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001138- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1139 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001150- Issue #2235: the C API function PyObject_HashNotImplemented and its
1151 interaction with the tp_hash slot (added in 2.6b2) are now documented
1152
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001153- Issue #643841: The language reference now provides more detailed
1154 coverage of the lookup process for special methods. The disclaimers
1155 regarding lack of coverage of new-style classes have also been
1156 removed, since the coverage is now fairly reasonable.

1160================================
1161
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001162*Release date: 17-Jul-2008*
1163
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001164Core and Builtins
1165-----------------
1166
Georg Brandl3e483f62008-07-16 22:57:41 +00001167- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1168 its methods now allow for items objects that can be converted to
1169 an integer using operator.index().
1170
Mark Dickinson64b7e502008-07-16 09:40:03 +00001171- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1172 produced a ValueError instead of giving the correct float.
1173
Eric Smitha5fa5a22008-07-16 00:11:49 +00001174- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1175 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1176
Mark Dickinson7103aa42008-07-15 19:08:33 +00001177- Issue #3008: the float type has a new instance method 'float.hex'
1178 and a new class method 'float.fromhex' to convert floating-point
1179 numbers to and from hexadecimal strings, respectively.
1180
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001181- Issue #2235: __hash__ is once again inherited by default. To allow
1182 collections.Hashable to remain meaningful in the presence of the
1183 default hash implementation (object.__hash__), it is now possible
1184 to explicit block inheritance of hash by setting __hash__=None at
1185 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1186 level.
1187
Nick Coghlanb028f502008-07-13 14:52:36 +00001188- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1189 the parent module cannot be found while performing an absolute import.
1190 This means that an incorrectly defined __package__ attribute will
1191 now only prevent relative imports in that module rather than causing
1192 all imports from that module to fail.
1193
Nick Coghlan14ff9942008-07-08 14:21:42 +00001194- Issue #2517: Allow unicode messages in Exceptions again by correctly
1195 bypassing the instance dictionary when looking up __unicode__ on
1196 new-style classes.
1197
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001198- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1199 set to a custom object whose write() method happens to install
1200 another file in sys.stdout.
1201
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001202- Issue #3088: Corrected a race condition in classes derived from
1203 threading.local: the first member set by a thread could be saved in
1204 another thread's dictionary.
1205
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001206- Issue #3004: Minor change to slice.indices(): the start and stop
1207 arguments are now treated identically, making the behaviour easier
1208 to describe and understand. For example, slice(None, -10,
1209 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1210 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1211 10, -1).
1212
Georg Brandl278fc502008-07-19 12:46:12 +00001213- Issue #3219: Calling a function with repeated keyword arguments,
1214 f(a=2, a=23), would not cause a syntax error. This was a regression
1215 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001216
Georg Brandl278fc502008-07-19 12:46:12 +00001217- Issue #2862: Make int and float freelist management consistent with
1218 other freelists. Changes their CompactFreeList apis into
1219 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001220

1223
Thomas Heller57adf222008-08-14 19:10:48 +00001224- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1225 api functions without holding the GIL, which could lead to a fatal
1226 error when they failed.
1227
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001228- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1242 a valid dlerror() message.
1243
Thomas Heller2bad6572008-07-15 17:19:50 +00001244- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1245 incomplete structure was created.
1246

1250
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001251- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001252
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001253- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1254 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001255 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001256 content-length. The problem had been corrected in the 2.4 branch, but never
1257 merged into trunk.
1258
Georg Brandle78fbcc2008-07-05 10:13:36 +00001259- Issue #2663: add filtering capability to shutil.copytree().

1664 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001665 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001666
1667 This is controlled by the configure argument ``--with-universal-archs``:
1668
1669 - ``--with-universal-archs=all``: install 4-way universal
1670
1671 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1672
1673 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1674
1675 This option should be used in combination with ``--enable-universalsdk=``.
1676
1677 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 +00001727- Issue #1631171: Re-implement the 'warnings' module in C (the
1728 original Python code has been kept as backup). This will allow for
1729 using the 'warning's machinery in such places as the parser where
1730 use of pure Python code is not possible. Both the ``showarning()``
1731 and ``formatwarning()`` gain an optional 'line' argument which is
1732 not called by default for backwards-compatibility reasons. Setting
1733 ``warnings.showwarning()`` to an implementation that lacks support
1734 for the ``line`` argument will raise a DeprecationWarning.

1758
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001759- The getpass module has been improved on Unix. It now uses /dev/tty
1760 by default and uses stderr instead of stdout. A GetPassWarning is
1761 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00001762

Georg Brandl3ee81df2008-05-17 18:14:43 +00001776- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001777 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001797- Issue #2550: The approach used by client/server code for obtaining
1798 ports to listen on in network-oriented tests has been refined in an
1799 effort to facilitate running multiple instances of the entire
1800 regression test suite in parallel without issue.
1801 test_support.bind_port() has been fixed such that it will always
1802 return a unique port -- which wasn't always the case with the
1803 previous implementation, especially if socket options had been set
1804 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1805 new implementation of bind_port() will actually raise an exception
1806 if it is passed an AF_INET/SOCK_STREAM socket with either the
1807 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1808 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1809 the socket it's been passed. This currently only applies to
1810 Windows. This option prevents any other sockets from binding to the
1811 host/port we've bound to, thus removing the possibility of the
1812 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1813 when a second SOCK_STREAM socket binds and accepts to a host/port
1814 that's already been bound by another socket. The optional preferred
1815 port parameter to bind_port() has been removed. Under no
1816 circumstances should tests be hard coding ports!
1817
1818 test_support.find_unused_port() has also been introduced, which will
1819 pass a temporary socket object to bind_port() in order to obtain an
1820 unused port. The temporary socket object is then closed and
1821 deleted, and the port is returned. This method should only be used
1822 for obtaining an unused port in order to pass to an external program
1823 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1824 a parameter to a server-oriented class that doesn't give you direct
1825 access to the underlying socket used.
1826
1827 Finally, test_support.HOST has been introduced, which should be used
1828 for the host argument of any relevant socket calls (i.e. bind and
1829 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001830

2103Core and builtins
2104-----------------
2105
Fred Drakea8ee94b2008-03-01 02:45:07 +00002106- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002107 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002108
Georg Brandlad61bc82008-02-23 15:11:18 +00002109- Issue #2067: file.__exit__() now calls subclasses' close() method.
2110
2111- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002112
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002113- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002114 issue 215555 for a discussion.
2115
Eric Smitha73fbe72008-02-23 03:09:44 +00002116- Added the future_builtins module, which contains hex() and oct().
2117 These are the PEP 3127 version of these functions, designed to be
2118 compatible with the hex() and oct() builtins from Python 3.0. They
2119 differ slightly in their output formats from the existing, unchanged
2120 Python 2.6 builtins. The expected usage of the future_builtins
2121 module is:
2122 from future_builtins import hex, oct
2123
Eric Smith7ef40bf2008-02-20 23:34:22 +00002124- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2125 exponents for exponents with absolute value < 100. Follows C99
2126 standard. This is a change on Windows, which would use 3 digits.
2127 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2128 so that any alterations it does to the resulting string will be
2129 available in stringlib/formatter.h (for float.__format__).
2130
Eric Smith5a3c1352008-02-19 13:21:56 +00002131- Implemented PEP 3101, Advanced String Formatting. This adds a new
2132 builtin format(); a format() method for str and unicode; a
2133 __format__() method to object, str, unicode, int, long, float, and
2134 datetime; the class string.Formatter; and the C API
2135 PyObject_Format().
2136
Georg Brandl3ee81df2008-05-17 18:14:43 +00002137- Fixed several potential crashes, all caused by specially crafted
2138 __del__ methods exploiting objects in temporarily inconsistent
2139 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002140
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002141- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002142 prevent a possible crash: an Abstract Base Class would try to access
2143 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002144
Georg Brandl3ee81df2008-05-17 18:14:43 +00002145- Fixed repr() and str() of complex numbers with infinity or nan as
2146 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002147
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148- Clear all free lists during a gc.collect() of the highest generation
2149 in order to allow pymalloc to free more arenas. Python may give back
2150 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002151
Georg Brandl3ee81df2008-05-17 18:14:43 +00002152- Issue #2045: Fix an infinite recursion triggered when printing a
2153 subclass of collections.defaultdict, if its default_factory is set
2154 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002155
Christian Heimesf75dbef2008-02-08 00:11:31 +00002156- Fixed a minor memory leak in dictobject.c. The content of the free
2157 list was not freed on interpreter shutdown.
2158
Georg Brandl3ee81df2008-05-17 18:14:43 +00002159- Limit free list of method and builtin function objects to 256
2160 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002161
Georg Brandl3ee81df2008-05-17 18:14:43 +00002162- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2163 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002164 to compact the internal free lists of pre-allocted ints and floats.
2165
Georg Brandl3ee81df2008-05-17 18:14:43 +00002166- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2167 calls. Python expected the return type int but the fork familie
2168 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002169
Georg Brandl3ee81df2008-05-17 18:14:43 +00002170- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2171 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002172
Georg Brandl3ee81df2008-05-17 18:14:43 +00002173- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2174 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002175
Georg Brandl3ee81df2008-05-17 18:14:43 +00002176- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2177 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002178
Georg Brandl3ee81df2008-05-17 18:14:43 +00002179- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2180 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002181
Georg Brandl3ee81df2008-05-17 18:14:43 +00002182- Patch #1473257: generator objects gain a gi_code attribute. This is
2183 the same object as the func_code attribute of the function that
2184 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002185
Georg Brandl3ee81df2008-05-17 18:14:43 +00002186- Issue #1920: "while 0" statements were completely removed by the
2187 compiler, even in the presence of an "else" clause, which is
2188 supposed to be run when the condition is false. Now the compiler
2189 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002190
Guido van Rossumeead05f2008-01-24 18:21:02 +00002191- A few crashers fixed: weakref_in_del.py (issue #1377858);
2192 loosing_dict_ref.py (issue #1303614, test67.py);
2193 borrowed_ref_[34].py (not in tracker).
2194
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002195- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002196 suppressed while an extension is loaded by calling SetErrorMode in
2197 dynload_win.c. The error is still reported properly.
2198
Georg Brandl3ee81df2008-05-17 18:14:43 +00002199- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002200 several extension methods and modules do not work without unicode
2201 support.
2202
Georg Brandl26543b12008-01-21 18:36:51 +00002203- Issue #1882: when compiling code from a string, encoding cookies in the
2204 second line of code were not always recognized correctly.
2205
Georg Brandl14404b62008-01-19 19:27:05 +00002206- Issue #1679: "0x" was taken as a valid integer literal.
2207
Georg Brandl6caad7d2008-01-26 14:19:22 +00002208- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002209 added.
2210
Christian Heimesc94e2b52008-01-14 04:13:37 +00002211- sys.float_info / PyFloat_GetInfo: The floating point information
2212 object was converted from a dict to a specialized structseq object.
2213
Georg Brandl3ee81df2008-05-17 18:14:43 +00002214- Patch #1816: Added sys.flags structseq. It exposes the status of
2215 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002216
Georg Brandl3ee81df2008-05-17 18:14:43 +00002217- Objects/structseq.c: Implemented new structseq representation. The
2218 patch makes structseqs (e.g. the return value of os.stat) more
2219 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002220
Georg Brandl3ee81df2008-05-17 18:14:43 +00002221- Patch #1700288: added a type attribute cache that caches method
2222 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002223
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002224- Bug #1776: __import__() no longer accepts filenames on any platform.
2225 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002226
Georg Brandlaed6c662008-01-07 17:25:53 +00002227- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2228
Georg Brandl3ee81df2008-05-17 18:14:43 +00002229- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2230 envvar and sys.dont_write_bytecode attribute. All these can be set
2231 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002232
Georg Brandl3ee81df2008-05-17 18:14:43 +00002233- Improve some exception messages when Windows fails to load an
2234 extension module. Now we get for example '%1 is not a valid Win32
2235 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002236
Georg Brandl3ee81df2008-05-17 18:14:43 +00002237- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002239- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2240 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002241
Christian Heimes0a8143f2007-12-18 23:22:54 +00002242- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002243 and INF. float("nan"), float("inf") and float("-inf") now work on
2244 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002245
Georg Brandl3ee81df2008-05-17 18:14:43 +00002246- Compiler now generates simpler and faster code for dictionary
2247 literals. The oparg for BUILD_MAP now indicates an estimated
2248 dictionary size. There is a new opcode, STORE_MAP, for adding
2249 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002250
Georg Brandl3ee81df2008-05-17 18:14:43 +00002251- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002253- Issue #1620: New property decorator syntax was modifying the
2254 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002255
Georg Brandl3ee81df2008-05-17 18:14:43 +00002256- Issue #1538: Avoid copying string in split/rsplit if the split char
2257 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002258
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002259- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002260 SystemError.
2261
Nick Coghlanef01d822007-12-03 12:55:17 +00002262- PEP 366: Allow explicit relative imports when executing modules
2263 inside packages with the -m switch via a new module level
2264 __package__ attribute.
2265
Georg Brandl3ee81df2008-05-17 18:14:43 +00002266- Issue #1402: Fix a crash on exit, when another thread is still
2267 running, and if the deallocation of its frames somehow calls the
2268 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002269

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00002273 attribute of an empty cell object.
2274
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Issue #1460: The utf-7 incremental decoder did not accept truncated
2276 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002277

2279 file can now be directly executed by passing their name to the
2280 interpreter. The directory/zipfile is automatically inserted as the
2281 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002282
Georg Brandl3ee81df2008-05-17 18:14:43 +00002283- Issue #1265: Fix a problem with sys.settrace, if the tracing
2284 function uses a generator expression when at the same time the
2285 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002286
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002287- sets and frozensets now have an isdisjoint() method.
2288
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002289- optimize the performance of builtin.sum().
2290
Neal Norwitz44f326e2007-10-05 05:29:17 +00002291- Fix warnings found by the new version of the Coverity checker.
2292
Georg Brandl3ee81df2008-05-17 18:14:43 +00002293- The enumerate() builtin function is no longer bounded to sequences
2294 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2295 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002296
Georg Brandl3ee81df2008-05-17 18:14:43 +00002297- Issue #1686386: Tuple's tp_repr did not take into account the
2298 possibility of having a self-referential tuple, which is possible
2299 from C code. Nor did object's tp_str consider that a type's tp_str
2300 could do something that could lead to an inifinite recursion.
2301 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2302 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002303
Georg Brandl3ee81df2008-05-17 18:14:43 +00002304- Issue #1164: It was possible to trigger deadlock when using the
2305 'print' statement to write to a file since the GIL was not released
2306 as needed. Now PyObject_Print() does the right thing along with
2307 various tp_print implementations of the built-in types and those in
2308 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002309
Georg Brandl3ee81df2008-05-17 18:14:43 +00002310- Issue #1147: Exceptions were directly allowing string exceptions in
2311 their throw() method even though string exceptions no longer
2312 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002313
Georg Brandl3ee81df2008-05-17 18:14:43 +00002314- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002317- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002318 PyObject_Call() never calling back out to Python code to trigger
2319 recursion depth updates/checks. Required the creation of a static
2320 RuntimeError instance in case normalizing an exception put the
2321 recursion check value past its limit. Fixes crashers
2322 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002323
Georg Brandl3ee81df2008-05-17 18:14:43 +00002324- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002337- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002338 __*__ attributes. (Some already existed, e.g., __doc__ and
2339 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002340
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002341- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00002348 "except E as target:". This is to provide forwards compatibility
2349 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002350
Brett Cannon229cee22007-05-05 01:34:02 +00002351- Deprecate BaseException.message as per PEP 352.

2369
Guido van Rossum143b5642007-03-23 04:58:42 +00002370- Bug #1683368: The object.__init__() and object.__new__() methods are
2371 now stricter in rejecting excess arguments. The only time when
2372 either allows excess arguments is when it is not overridden and the
2373 other one is. For backwards compatibility, when both are
2374 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002375 warning later). Also, type.__init__() insists on the same signature
2376 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002377
Georg Brandl3ee81df2008-05-17 18:14:43 +00002378- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2379 object to complex using its __complex__() method before falling back
2380 to the __float__() method. Therefore, the functions in the cmath
2381 module now can operate on objects that define a __complex__()
2382 method.

2399
Georg Brandl7b9c5552007-03-12 14:30:05 +00002400- Bug #1678647: write a newline after printing an exception in any
2401 case, even when converting the value to a string failed.
2402
Georg Brandl871f1bc2007-03-12 13:17:36 +00002403- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002404 its argument, if it exists. If not, it will work like before. This
2405 allows customizing the output of dir() in the presence of a
2406 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002407
Collin Winter276887b2007-03-12 16:11:39 +00002408- Patch #922167: Python no longer segfaults when faced with infinitely
2409 self-recursive reload() calls (as reported by bug #742342).

2416 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002417
Georg Brandlaa2321b2007-03-07 00:40:28 +00002418- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002419 makes the filenames the warning module prints much more sensible
2420 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002421

Georg Brandl0fca97a2007-03-05 22:28:08 +00002433- Patch #1674228: when assigning a slice (old-style), check for the
2434 sq_ass_slice instead of the sq_slice slot.
2435
Georg Brandl3ee81df2008-05-17 18:14:43 +00002436- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003062- unittest now verifies more of its assumptions. In particular,
3063 TestCase and TestSuite subclasses (not instances) are no longer
3064 accepted in TestSuite.addTest(). This should cause no
3065 incompatibility since it never made sense with ordinary subclasses
3066 -- the failure just occurred later, with a more cumbersome
3067 exception.

3346 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003347
Georg Brandl3ee81df2008-05-17 18:14:43 +00003348- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3349 with RFC 3207 and forgets any knowledge obtained from the server not
3350 obtained from the TLS negotiation itself. Patch contributed by Bill
3351 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003352
Georg Brandl3ee81df2008-05-17 18:14:43 +00003353- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003354 that the SMTP.starttls() caller no longer needs to call ehlo()
3355 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003356 does not claim to support starttls. Adds the
3357 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3438 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3439 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003456 time so that opening a database previously created with the DB_DUP
3457 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3458 opens. Specifically: dictionary assignment to a DB object will
3459 replace all values for a given key when the database allows
3460 duplicate values. DB users should use DB.put(k, v) when they want
3461 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003462

3468 characters with ASCII value less than 32. Also, it correctly quotes
3469 dots only if they occur on a single line, as opposed to the previous
3470 behavior of quoting dots if they are the second character of any
3471 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003472

Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3802 to ``PyTuple_SetItem``, it can be used to populate a brand new
3803 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003805- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003807- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3808 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3809 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003810
3811- Patch #1720595: add T_BOOL to the range of structmember types.
3812
3813- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3814 ``PyFloat_GetInfo()`` to the float API.
3815
Georg Brandl3ee81df2008-05-17 18:14:43 +00003816- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3817 of w# format code incorrectly truncated the length to an int, even
3818 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3819 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003820
Georg Brandl3ee81df2008-05-17 18:14:43 +00003821- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3822 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003823
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824- PEP 3123: Provide forward compatibility with Python 3.0, while
3825 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3826 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003827
Georg Brandl3ee81df2008-05-17 18:14:43 +00003828- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3829 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003830
3831- Patch #1733960: Allow T_LONGLONG to accept ints.
3832
3833- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3834
Christian Heimes000a0742008-01-03 22:16:32 +00003835- Added a new API function ``PyImport_ImportModuleNoBlock``.
3836
Georg Brandl6caad7d2008-01-26 14:19:22 +00003837- Bug #1637022: Prefix AST symbols with _Py_.
3838
3839- Fix some leftovers from the conversion from int to Py_ssize_t
3840 (relevant to strings and sequences of more than 2**31 items).
3841
3842- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3843 outside of pystate.c and should not be necessary.
3844
Georg Brandl3ee81df2008-05-17 18:14:43 +00003845- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3846 absolute imports. In earlier versions they might have used relative
3847 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003848
Georg Brandl3ee81df2008-05-17 18:14:43 +00003849- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3850 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003851
Georg Brandl3ee81df2008-05-17 18:14:43 +00003852- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3853 macro so it can be used as an expression.

3858
Georg Brandl3ee81df2008-05-17 18:14:43 +00003859- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3860 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3861 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3862 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003863
Georg Brandl3ee81df2008-05-17 18:14:43 +00003864- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
3865 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00003875- buildtools now raises a DeprecationWarning.
3876
Georg Brandl3ee81df2008-05-17 18:14:43 +00003877- Removed the macfs module. It had been deprecated since Python 2.5.
3878 This lead to the deprecation of macostools.touched() as it relied
3879 solely on macfs and was a no-op under OS X.
