363 traditional 2.x file object.

398 302 conformant loader) will now work correctly in most cases (they
399 are still subject to the constraints that exist for all code running
400 from inside a module loaded via a PEP 302 loader and attempting to

559What's New in Python 2.6.1
560==========================
561
562*Release date: 04-Dec-2008*
563
564Core and Builtins
565-----------------
566
567- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
568 interpreter to abort ("Fatal Python error: Could not reset the stack!")
569 instead of throwing a MemoryError.
570
571- Issue #4367: Python would segfault during compiling when the unicodedata
572 module couldn't be imported and \N escapes were present.
573
574- Issue #4348: Some bytearray methods returned that didn't cause any change to
575 the bytearray, returned the same bytearray instead of a copy.
576
577- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
578
579- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
580
581- Issue #4048: The parser module now correctly validates relative imports.
582
583- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
584 exec statement.
585
586- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
587 method does not return iterators for the 4th and 5th items.
588
589- Issue #4209: Enabling unicode_literals and the print_function in the same
590 __future__ import didn't work.
591
592- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
593 returned a path longer than MAX_PATH. (But It's doubtful this code path is
594 really executed because I cannot move to such directory on win2k)
595
596- Issue #4069: When set.remove(element) is used with a set element, the element
597 is temporarily replaced with an equivalent frozenset. But the eventual
598 KeyError would always report the empty frozenset([]) as the missing key. Now
599 it correctly refers to the initial element.
600
601- Fixed C99 style comments in several files. Python is now C89 compatible
602 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000749- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
750
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000751- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
752 PyString_FromFormat or PyErr_Format to display size_t values. The macro
753 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
754 ``printf`` function, whereas PyString_FromFormat has an independent
755 implementation and uses "%zd" on all platforms for size_t values.
756 This makes a difference on win64, where ``printf`` needs "%Id" to display
757 64bit values.
758
Benjamin Peterson97179b02008-09-09 20:55:01 +0000759- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
760 error.
761
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000762- Issue #3777: long() applied to a float object now always return a long
763 object; previously an int would be returned for small values. the __long__
764 method is allowed to return either an int or a long, but the behaviour of
765 float objects should not change to respect backward compatibility.
766
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000767- Issue #3751: str.rpartition would perform a left-partition when called with
768 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000773 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000774 was correctly parsed but parsing of subsequent arguments failed.
775
Vinay Sajip35e3b032008-09-01 14:33:59 +0000776- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000777 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
778 mechanism. In the process, fix a bug where isinstance() and issubclass(),
779 when given a tuple of classes as second argument, were looking up
780 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
781 type object.

852 warnings.catch_warnings() along with some API cleanup. Expanding the tests
853 for catch_warnings() also led to an improvement in the raising of a
854 DeprecationWarning related to warnings.warn_explicit().

922Core and Builtins
923-----------------
924
Guido van Rossumf8402962008-08-20 15:01:50 +0000925- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
926 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
927 extensions do not automatically benefit from the class attribute
928 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
929 to their tp_flags field if they care. This is a backwards
930 compatibility feature; in 3.0, all types will use the cache by
931 default.
932
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000933- Keyword arguments can now follow starred arguments. (``f(a, *args,
934 keyword=23)`` is now valid syntax.)
935
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000936- ctypes function pointers that are COM methods have a boolean True
937 value again.
938
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000939- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
940 by denying s# to parse objects that have a releasebuffer procedure,
941 and introducing s*.
942
Georg Brandl1e13ea92008-08-11 09:07:59 +0000943- Issue #3537: Fix an assertion failure when an empty but presized dict
944 object was stored in the freelist.
945
Mark Dickinsonb6467572008-08-04 21:30:09 +0000946- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
947 ValueError consistently across platforms.
948
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000949- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
950 (64bit Unix, for example), unichr() would truncate its argument and return
951 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
952
Neal Norwitze7d8be82008-07-31 17:17:14 +0000953- Apply security patches from Apple.
954
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000955- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
956 PyErr_ExceptionMatches returns 0 when an exception occurs there.
957
Antoine Pitrou92f82162008-07-25 22:22:08 +0000958- Issue #1819: function calls with several named parameters are now on
959 average 35% faster (as measured by pybench).
960
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000961- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
962 the python debugger steps into a class statement: the free variables (local
963 variables defined in an outer scope) would be deleted from the outer scope.
964
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000965- Issue #2620: Overflow checking when allocating or reallocating memory
966 was not always being done properly in some python types and extension
967 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
968 all been updated to perform better checks and places in the code that
969 would previously leak memory on the error path when such an allocation
970 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +0000977- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
978 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
979
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000980- Issue #2234: distutils failed for some versions of the cygwin compiler. The
981 version reported by these tools does not necessarily follow the python
982 version numbering scheme, so the module is less strict when parsing it.

985 under the stricter __hash__ inheritance rules in 3.0. Several types
986 which did not meet the rules for hash invariants and were already
987 unhashable in 3.0 have now been explicitly flagged as unhashable in
988 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
989 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)

1038 to _sre.compile() will now be rejected. This should not affect anybody

1043 it wasn't initialized during instantiation.
1044
Brett Cannon3aa2a492008-08-06 22:28:09 +00001045- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1046 the reload() built-in has been removed.

Benjamin Peterson01a24322008-07-28 23:35:27 +00001059- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001060 asking for a specific length. This problem only affected files opened
1061 using the new "io" module, not the built-in open() function.

1087 file name rather than a ZipInfo instance, so files are extracted with
1088 mode 0600 rather than 000 under Unix.
1089

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001102- Issue #2235: the C API function PyObject_HashNotImplemented and its
1103 interaction with the tp_hash slot (added in 2.6b2) are now documented
1104
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001105- Issue #643841: The language reference now provides more detailed
1106 coverage of the lookup process for special methods. The disclaimers
1107 regarding lack of coverage of new-style classes have also been

1112================================
1113
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001114*Release date: 17-Jul-2008*
1115
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001116Core and Builtins
1117-----------------
1118
Georg Brandl3e483f62008-07-16 22:57:41 +00001119- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1120 its methods now allow for items objects that can be converted to
1121 an integer using operator.index().
1122
Mark Dickinson64b7e502008-07-16 09:40:03 +00001123- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1124 produced a ValueError instead of giving the correct float.
1125
Eric Smitha5fa5a22008-07-16 00:11:49 +00001126- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1127 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1128
Mark Dickinson7103aa42008-07-15 19:08:33 +00001129- Issue #3008: the float type has a new instance method 'float.hex'
1130 and a new class method 'float.fromhex' to convert floating-point
1131 numbers to and from hexadecimal strings, respectively.
1132
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001133- Issue #2235: __hash__ is once again inherited by default. To allow
1134 collections.Hashable to remain meaningful in the presence of the
1135 default hash implementation (object.__hash__), it is now possible
1136 to explicit block inheritance of hash by setting __hash__=None at
1137 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1138 level.
1139
Nick Coghlanb028f502008-07-13 14:52:36 +00001140- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1141 the parent module cannot be found while performing an absolute import.
1142 This means that an incorrectly defined __package__ attribute will
1143 now only prevent relative imports in that module rather than causing
1144 all imports from that module to fail.
1145
Nick Coghlan14ff9942008-07-08 14:21:42 +00001146- Issue #2517: Allow unicode messages in Exceptions again by correctly
1147 bypassing the instance dictionary when looking up __unicode__ on
1148 new-style classes.
1149
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001150- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1151 set to a custom object whose write() method happens to install
1152 another file in sys.stdout.
1153
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001154- Issue #3088: Corrected a race condition in classes derived from
1155 threading.local: the first member set by a thread could be saved in
1156 another thread's dictionary.
1157
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001158- Issue #3004: Minor change to slice.indices(): the start and stop
1159 arguments are now treated identically, making the behaviour easier
1160 to describe and understand. For example, slice(None, -10,
1161 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1162 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1163 10, -1).
1164
Georg Brandl278fc502008-07-19 12:46:12 +00001165- Issue #3219: Calling a function with repeated keyword arguments,
1166 f(a=2, a=23), would not cause a syntax error. This was a regression
1167 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001168
Georg Brandl278fc502008-07-19 12:46:12 +00001169- Issue #2862: Make int and float freelist management consistent with
1170 other freelists. Changes their CompactFreeList apis into
1171 ClearFreeList apis and calls them via gc.collect().

1177 api functions without holding the GIL, which could lead to a fatal
1178 error when they failed.
1179
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001180- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Vinay Sajip51e65192008-07-18 09:01:10 +00001191- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001205- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1206 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001207 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001208 content-length. The problem had been corrected in the 2.4 branch, but never
1209 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001224- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1225 handling is now the same as that of other special attributes like __name__).
1226
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001227- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

1616 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001617 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001618
1619 This is controlled by the configure argument ``--with-universal-archs``:
1620
1621 - ``--with-universal-archs=all``: install 4-way universal
1622
1623 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1624
1625 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1626
1627 This option should be used in combination with ``--enable-universalsdk=``.
1628
1629 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 +00001679- Issue #1631171: Re-implement the 'warnings' module in C (the
1680 original Python code has been kept as backup). This will allow for
1681 using the 'warning's machinery in such places as the parser where
1682 use of pure Python code is not possible. Both the ``showarning()``
1683 and ``formatwarning()`` gain an optional 'line' argument which is
1684 not called by default for backwards-compatibility reasons. Setting
1685 ``warnings.showwarning()`` to an implementation that lacks support
1686 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001749- Issue #2550: The approach used by client/server code for obtaining
1750 ports to listen on in network-oriented tests has been refined in an
1751 effort to facilitate running multiple instances of the entire
1752 regression test suite in parallel without issue.
1753 test_support.bind_port() has been fixed such that it will always
1754 return a unique port -- which wasn't always the case with the
1755 previous implementation, especially if socket options had been set
1756 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1757 new implementation of bind_port() will actually raise an exception
1758 if it is passed an AF_INET/SOCK_STREAM socket with either the
1759 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1760 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1761 the socket it's been passed. This currently only applies to
1762 Windows. This option prevents any other sockets from binding to the
1763 host/port we've bound to, thus removing the possibility of the
1764 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1765 when a second SOCK_STREAM socket binds and accepts to a host/port
1766 that's already been bound by another socket. The optional preferred
1767 port parameter to bind_port() has been removed. Under no
1768 circumstances should tests be hard coding ports!
1769
1770 test_support.find_unused_port() has also been introduced, which will
1771 pass a temporary socket object to bind_port() in order to obtain an
1772 unused port. The temporary socket object is then closed and
1773 deleted, and the port is returned. This method should only be used
1774 for obtaining an unused port in order to pass to an external program
1775 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1776 a parameter to a server-oriented class that doesn't give you direct
1777 access to the underlying socket used.
1778
1779 Finally, test_support.HOST has been introduced, which should be used
1780 for the host argument of any relevant socket calls (i.e. bind and
1781 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001782
1783 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001784 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001785 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1786 test_asynchat and test_socket_ssl.
1787
Georg Brandl3ee81df2008-05-17 18:14:43 +00001788 It is now possible for multiple instances of the regression test
1789 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00001843- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00001844 \Uxxxxxxxx did not accept values outside the Basic Multilingual
1845 Plane. This affected raw unicode literals and the
1846 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
1847 this case, like normal unicode literals and the 'unicode-escape'
1848 codec.

2071 differ slightly in their output formats from the existing, unchanged

2073 module is:
2074 from future_builtins import hex, oct

2077 exponents for exponents with absolute value < 100. Follows C99
2078 standard. This is a change on Windows, which would use 3 digits.
2079 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2080 so that any alterations it does to the resulting string will be
2081 available in stringlib/formatter.h (for float.__format__).
2082
Eric Smith5a3c1352008-02-19 13:21:56 +00002083- Implemented PEP 3101, Advanced String Formatting. This adds a new
2084 builtin format(); a format() method for str and unicode; a
2085 __format__() method to object, str, unicode, int, long, float, and
2086 datetime; the class string.Formatter; and the C API
2087 PyObject_Format().
2088
Georg Brandl3ee81df2008-05-17 18:14:43 +00002089- Fixed several potential crashes, all caused by specially crafted
2090 __del__ methods exploiting objects in temporarily inconsistent
2091 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002092
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002093- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002094 prevent a possible crash: an Abstract Base Class would try to access
2095 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002096

Georg Brandl3ee81df2008-05-17 18:14:43 +00002100- Clear all free lists during a gc.collect() of the highest generation
2101 in order to allow pymalloc to free more arenas. Python may give back
2102 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002103
Georg Brandl3ee81df2008-05-17 18:14:43 +00002104- Issue #2045: Fix an infinite recursion triggered when printing a
2105 subclass of collections.defaultdict, if its default_factory is set
2106 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002107
Christian Heimesf75dbef2008-02-08 00:11:31 +00002108- Fixed a minor memory leak in dictobject.c. The content of the free
2109 list was not freed on interpreter shutdown.
2110
Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Limit free list of method and builtin function objects to 256
2112 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002113
Georg Brandl3ee81df2008-05-17 18:14:43 +00002114- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2115 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002116 to compact the internal free lists of pre-allocted ints and floats.
2117
Georg Brandl3ee81df2008-05-17 18:14:43 +00002118- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2119 calls. Python expected the return type int but the fork familie
2120 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002121
Georg Brandl3ee81df2008-05-17 18:14:43 +00002122- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2123 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002124

Georg Brandl3ee81df2008-05-17 18:14:43 +00002134- Patch #1473257: generator objects gain a gi_code attribute. This is
2135 the same object as the func_code attribute of the function that
2136 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002137
Georg Brandl3ee81df2008-05-17 18:14:43 +00002138- Issue #1920: "while 0" statements were completely removed by the
2139 compiler, even in the presence of an "else" clause, which is
2140 supposed to be run when the condition is false. Now the compiler
2141 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002142
Guido van Rossumeead05f2008-01-24 18:21:02 +00002143- A few crashers fixed: weakref_in_del.py (issue #1377858);
2144 loosing_dict_ref.py (issue #1303614, test67.py);
2145 borrowed_ref_[34].py (not in tracker).
2146
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002147- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002148 suppressed while an extension is loaded by calling SetErrorMode in
2149 dynload_win.c. The error is still reported properly.
2150
Georg Brandl3ee81df2008-05-17 18:14:43 +00002151- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002152 several extension methods and modules do not work without unicode
2153 support.
2154
Georg Brandl26543b12008-01-21 18:36:51 +00002155- Issue #1882: when compiling code from a string, encoding cookies in the
2156 second line of code were not always recognized correctly.
2157
Georg Brandl14404b62008-01-19 19:27:05 +00002158- Issue #1679: "0x" was taken as a valid integer literal.
2159
Georg Brandl6caad7d2008-01-26 14:19:22 +00002160- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002161 added.
2162
Christian Heimesc94e2b52008-01-14 04:13:37 +00002163- sys.float_info / PyFloat_GetInfo: The floating point information
2164 object was converted from a dict to a specialized structseq object.
2165
Georg Brandl3ee81df2008-05-17 18:14:43 +00002166- Patch #1816: Added sys.flags structseq. It exposes the status of
2167 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002168
Georg Brandl3ee81df2008-05-17 18:14:43 +00002169- Objects/structseq.c: Implemented new structseq representation. The
2170 patch makes structseqs (e.g. the return value of os.stat) more
2171 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002172
Georg Brandl3ee81df2008-05-17 18:14:43 +00002173- Patch #1700288: added a type attribute cache that caches method
2174 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002175
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002176- Bug #1776: __import__() no longer accepts filenames on any platform.
2177 The first parameter to __import__() must be a valid module name.

2182 envvar and sys.dont_write_bytecode attribute. All these can be set
2183 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002184
Georg Brandl3ee81df2008-05-17 18:14:43 +00002185- Improve some exception messages when Windows fails to load an
2186 extension module. Now we get for example '%1 is not a valid Win32
2187 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002188

Georg Brandl3ee81df2008-05-17 18:14:43 +00002195 and INF. float("nan"), float("inf") and float("-inf") now work on
2196 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002197
Georg Brandl3ee81df2008-05-17 18:14:43 +00002198- Compiler now generates simpler and faster code for dictionary
2199 literals. The oparg for BUILD_MAP now indicates an estimated

2244
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- The enumerate() builtin function is no longer bounded to sequences
2246 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2247 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002248
Georg Brandl3ee81df2008-05-17 18:14:43 +00002249- Issue #1686386: Tuple's tp_repr did not take into account the
2250 possibility of having a self-referential tuple, which is possible
2251 from C code. Nor did object's tp_str consider that a type's tp_str
2252 could do something that could lead to an inifinite recursion.
2253 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2254 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002255
Georg Brandl3ee81df2008-05-17 18:14:43 +00002256- Issue #1164: It was possible to trigger deadlock when using the
2257 'print' statement to write to a file since the GIL was not released
2258 as needed. Now PyObject_Print() does the right thing along with
2259 various tp_print implementations of the built-in types and those in
2260 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002261

Georg Brandl3ee81df2008-05-17 18:14:43 +00002270 PyObject_Call() never calling back out to Python code to trigger
2271 recursion depth updates/checks. Required the creation of a static
2272 RuntimeError instance in case normalizing an exception put the
2273 recursion check value past its limit. Fixes crashers

2321
Guido van Rossum143b5642007-03-23 04:58:42 +00002322- Bug #1683368: The object.__init__() and object.__new__() methods are
2323 now stricter in rejecting excess arguments. The only time when
2324 either allows excess arguments is when it is not overridden and the
2325 other one is. For backwards compatibility, when both are
2326 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002327 warning later). Also, type.__init__() insists on the same signature
2328 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002330- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2331 object to complex using its __complex__() method before falling back
2332 to the __float__() method. Therefore, the functions in the cmath
2333 module now can operate on objects that define a __complex__()
2334 method.

2345 its type.

2351
Georg Brandl7b9c5552007-03-12 14:30:05 +00002352- Bug #1678647: write a newline after printing an exception in any
2353 case, even when converting the value to a string failed.
2354
Georg Brandl871f1bc2007-03-12 13:17:36 +00002355- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002356 its argument, if it exists. If not, it will work like before. This
2357 allows customizing the output of dir() in the presence of a
2358 __getattr__().

2367 parthensized forms. This means complex(repr(x)) now works instead of
2368 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002369
Georg Brandlaa2321b2007-03-07 00:40:28 +00002370- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002371 makes the filenames the warning module prints much more sensible
2372 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002373

Georg Brandl0fca97a2007-03-05 22:28:08 +00002385- Patch #1674228: when assigning a slice (old-style), check for the
2386 sq_ass_slice instead of the sq_slice slot.
2387
Georg Brandl3ee81df2008-05-17 18:14:43 +00002388- When printing an unraisable error, don't print exceptions. before
2389 the name. This duplicates the behavior whening normally printing
2390 exceptions.

2399 created a weakref on itself during a __del__ call for new-style
2400 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00002440- Bug #1545497: when given an explicit base, int() did ignore NULs
2441 embedded in the string to convert.
2442
Georg Brandl846f73a2006-10-08 07:11:54 +00002443- Bug #1569998: break inside a try statement (outside a loop) is now
2444 recognized and rejected.
2445

Neal Norwitzdac090d2006-09-05 03:53:08 +00002490- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00002491 generator expressions (x for x, in ... ) works again. Fixing this
2492 problem required changing the .pyc magic number. This means that
2493 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002923 AttributeError instead of an IOError when the server's response

3015 TestCase and TestSuite subclasses (not instances) are no longer

3018 -- the failure just occurred later, with a more cumbersome
3019 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003296- The implementation of UnicodeError objects has been simplified
3297 (start and end attributes are now stored directly as Py_ssize_t
3298 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003299
Georg Brandl3ee81df2008-05-17 18:14:43 +00003300- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3301 with RFC 3207 and forgets any knowledge obtained from the server not
3302 obtained from the TLS negotiation itself. Patch contributed by Bill
3303 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003304
Georg Brandl3ee81df2008-05-17 18:14:43 +00003305- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003306 that the SMTP.starttls() caller no longer needs to call ehlo()
3307 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003308 does not claim to support starttls. Adds the
3309 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3310 Fenner.

3390 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3391 silently miscode subclasses of those types. Now, it raises a
3392 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003393

Georg Brandl3ee81df2008-05-17 18:14:43 +00003408 time so that opening a database previously created with the DB_DUP
3409 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3410 opens. Specifically: dictionary assignment to a DB object will
3411 replace all values for a given key when the database allows
3412 duplicate values. DB users should use DB.put(k, v) when they want
3413 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003414

3420 characters with ASCII value less than 32. Also, it correctly quotes
3421 dots only if they occur on a single line, as opposed to the previous
3422 behavior of quoting dots if they are the second character of any
3423 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003424
