Ezio Melotti86e5e172010-07-03 05:34:39 +000084- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
85 start byte and the continuation byte(s) are now considered invalid, instead
86 of the number of bytes specified by the start byte.
87 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
88 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
89 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
90 Previous versions returned a single u'\ufffd'.

122 processing: any non-float non-integer argument is now converted to
123 an integer (if possible) using its __int__ method. Previously, only
124 small arguments were treated this way; larger arguments (those whose
125 __int__ was outside the range of a C long) would produce a TypeError.

1728What's New in Python 2.6.1
1729==========================
1730
1731*Release date: 04-Dec-2008*
1732
1733Core and Builtins
1734-----------------
1735
1736- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1737 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1738 instead of throwing a MemoryError.
1739
1740- Issue #4367: Python would segfault during compiling when the unicodedata
1741 module couldn't be imported and \N escapes were present.
1742
1743- Issue #4348: Some bytearray methods returned that didn't cause any change to
1744 the bytearray, returned the same bytearray instead of a copy.
1745
1746- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1747
1748- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1749
1750- Issue #4048: The parser module now correctly validates relative imports.
1751
1752- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1753 exec statement.
1754
1755- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1756 method does not return iterators for the 4th and 5th items.
1757
1758- Issue #4209: Enabling unicode_literals and the print_function in the same
1759 __future__ import didn't work.
1760
1761- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1762 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1763 really executed because I cannot move to such directory on win2k)
1764
1765- Issue #4069: When set.remove(element) is used with a set element, the element
1766 is temporarily replaced with an equivalent frozenset. But the eventual
1767 KeyError would always report the empty frozenset([]) as the missing key. Now
1768 it correctly refers to the initial element.
1769
1770- Fixed C99 style comments in several files. Python is now C89 compatible
1771 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001918- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1919
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001920- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1921 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1922 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1923 ``printf`` function, whereas PyString_FromFormat has an independent
1924 implementation and uses "%zd" on all platforms for size_t values.
1925 This makes a difference on win64, where ``printf`` needs "%Id" to display
1926 64bit values.
1927
Benjamin Peterson97179b02008-09-09 20:55:01 +00001928- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1929 error.
1930
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001931- Issue #3777: long() applied to a float object now always return a long
1932 object; previously an int would be returned for small values. the __long__
1933 method is allowed to return either an int or a long, but the behaviour of
1934 float objects should not change to respect backward compatibility.
1935
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001936- Issue #3751: str.rpartition would perform a left-partition when called with
1937 a unicode argument.
1938
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001939- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001942 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001943 was correctly parsed but parsing of subsequent arguments failed.
1944
Vinay Sajip35e3b032008-09-01 14:33:59 +00001945- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001946 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1947 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1948 when given a tuple of classes as second argument, were looking up
1949 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1950 type object.
1951
Neal Norwitz18aa3882008-08-24 05:04:52 +00001952- Fix crashes on memory allocation failure found with failmalloc.
1953
1954- Fix memory leaks found with valgrind and update suppressions file.
1955
1956- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Brett Cannon1eaf0742008-09-02 01:25:16 +00002021 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2022 for catch_warnings() also led to an improvement in the raising of a

2091Core and Builtins
2092-----------------
2093
Guido van Rossumf8402962008-08-20 15:01:50 +00002094- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2095 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2096 extensions do not automatically benefit from the class attribute
2097 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2098 to their tp_flags field if they care. This is a backwards
2099 compatibility feature; in 3.0, all types will use the cache by
2100 default.
2101
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002102- Keyword arguments can now follow starred arguments. (``f(a, *args,
2103 keyword=23)`` is now valid syntax.)
2104
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002105- ctypes function pointers that are COM methods have a boolean True
2106 value again.
2107
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002108- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2109 by denying s# to parse objects that have a releasebuffer procedure,
2110 and introducing s*.
2111
Georg Brandl1e13ea92008-08-11 09:07:59 +00002112- Issue #3537: Fix an assertion failure when an empty but presized dict
2113 object was stored in the freelist.
2114
Mark Dickinsonb6467572008-08-04 21:30:09 +00002115- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2116 ValueError consistently across platforms.
2117
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002118- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2119 (64bit Unix, for example), unichr() would truncate its argument and return
2120 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2121
Neal Norwitze7d8be82008-07-31 17:17:14 +00002122- Apply security patches from Apple.
2123
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002124- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2125 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2126
Antoine Pitrou92f82162008-07-25 22:22:08 +00002127- Issue #1819: function calls with several named parameters are now on
2128 average 35% faster (as measured by pybench).
2129
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002130- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2131 the python debugger steps into a class statement: the free variables (local
2132 variables defined in an outer scope) would be deleted from the outer scope.
2133
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002134- Issue #2620: Overflow checking when allocating or reallocating memory
2135 was not always being done properly in some python types and extension
2136 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2137 all been updated to perform better checks and places in the code that
2138 would previously leak memory on the error path when such an allocation
2139 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002144- Issue #3612: Added some missing basic types in ctypes.wintypes.
2145
Benjamin Petersone977ad42008-08-20 01:42:01 +00002146- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2147 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2148
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002149- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2150 version reported by these tools does not necessarily follow the python
2151 version numbering scheme, so the module is less strict when parsing it.
2152
Nick Coghlanf70385a2008-08-18 12:42:46 +00002153- Issue #2235: Added Py3k warnings for types which will become unhashable
2154 under the stricter __hash__ inheritance rules in 3.0. Several types
2155 which did not meet the rules for hash invariants and were already
2156 unhashable in 3.0 have now been explicitly flagged as unhashable in
2157 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2158 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2159
Brett Cannon88f801d2008-08-18 00:46:22 +00002160- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2286-----------------
2287
Georg Brandl3e483f62008-07-16 22:57:41 +00002288- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2289 its methods now allow for items objects that can be converted to
2290 an integer using operator.index().
2291
Mark Dickinson64b7e502008-07-16 09:40:03 +00002292- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2293 produced a ValueError instead of giving the correct float.
2294
Eric Smitha5fa5a22008-07-16 00:11:49 +00002295- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2296 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2297
Mark Dickinson7103aa42008-07-15 19:08:33 +00002298- Issue #3008: the float type has a new instance method 'float.hex'
2299 and a new class method 'float.fromhex' to convert floating-point
2300 numbers to and from hexadecimal strings, respectively.
2301
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002302- Issue #2235: __hash__ is once again inherited by default. To allow
2303 collections.Hashable to remain meaningful in the presence of the
2304 default hash implementation (object.__hash__), it is now possible
2305 to explicit block inheritance of hash by setting __hash__=None at
2306 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2307 level.
2308
Nick Coghlanb028f502008-07-13 14:52:36 +00002309- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2310 the parent module cannot be found while performing an absolute import.
2311 This means that an incorrectly defined __package__ attribute will
2312 now only prevent relative imports in that module rather than causing
2313 all imports from that module to fail.
2314
Nick Coghlan14ff9942008-07-08 14:21:42 +00002315- Issue #2517: Allow unicode messages in Exceptions again by correctly

2325 another thread's dictionary.
2326
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002327- Issue #3004: Minor change to slice.indices(): the start and stop
2328 arguments are now treated identically, making the behaviour easier
2329 to describe and understand. For example, slice(None, -10,
2330 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2331 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2332 10, -1).
2333
Georg Brandl278fc502008-07-19 12:46:12 +00002334- Issue #3219: Calling a function with repeated keyword arguments,
2335 f(a=2, a=23), would not cause a syntax error. This was a regression
2336 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002374- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2375 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002376 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002377 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002784- On MacOS X it is now possible to install the framework in 64-bit
2785 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002786 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002787
2788 This is controlled by the configure argument ``--with-universal-archs``:
2789
2790 - ``--with-universal-archs=all``: install 4-way universal
2791
2792 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2793
2794 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2795
2796 This option should be used in combination with ``--enable-universalsdk=``.
2797
2798 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 +00002848- Issue #1631171: Re-implement the 'warnings' module in C (the
2849 original Python code has been kept as backup). This will allow for
2850 using the 'warning's machinery in such places as the parser where
2851 use of pure Python code is not possible. Both the ``showarning()``
2852 and ``formatwarning()`` gain an optional 'line' argument which is
2853 not called by default for backwards-compatibility reasons. Setting
2854 ``warnings.showwarning()`` to an implementation that lacks support
2855 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002918- Issue #2550: The approach used by client/server code for obtaining
2919 ports to listen on in network-oriented tests has been refined in an
2920 effort to facilitate running multiple instances of the entire
2921 regression test suite in parallel without issue.
2922 test_support.bind_port() has been fixed such that it will always
2923 return a unique port -- which wasn't always the case with the
2924 previous implementation, especially if socket options had been set
2925 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2926 new implementation of bind_port() will actually raise an exception
2927 if it is passed an AF_INET/SOCK_STREAM socket with either the
2928 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2929 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2930 the socket it's been passed. This currently only applies to
2931 Windows. This option prevents any other sockets from binding to the
2932 host/port we've bound to, thus removing the possibility of the
2933 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2934 when a second SOCK_STREAM socket binds and accepts to a host/port
2935 that's already been bound by another socket. The optional preferred
2936 port parameter to bind_port() has been removed. Under no
2937 circumstances should tests be hard coding ports!
2938
2939 test_support.find_unused_port() has also been introduced, which will
2940 pass a temporary socket object to bind_port() in order to obtain an
2941 unused port. The temporary socket object is then closed and
2942 deleted, and the port is returned. This method should only be used
2943 for obtaining an unused port in order to pass to an external program
2944 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2945 a parameter to a server-oriented class that doesn't give you direct
2946 access to the underlying socket used.
2947
2948 Finally, test_support.HOST has been introduced, which should be used
2949 for the host argument of any relevant socket calls (i.e. bind and
2950 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002951
2952 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002953 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002954 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2955 test_asynchat and test_socket_ssl.
2956
Georg Brandl3ee81df2008-05-17 18:14:43 +00002957 It is now possible for multiple instances of the regression test
2958 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003012- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003013 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3014 Plane. This affected raw unicode literals and the
3015 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3016 this case, like normal unicode literals and the 'unicode-escape'
3017 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00003237- Added the future_builtins module, which contains hex() and oct().
3238 These are the PEP 3127 version of these functions, designed to be
3239 compatible with the hex() and oct() builtins from Python 3.0. They
3240 differ slightly in their output formats from the existing, unchanged
3241 Python 2.6 builtins. The expected usage of the future_builtins
3242 module is:
3243 from future_builtins import hex, oct
3244
Eric Smith7ef40bf2008-02-20 23:34:22 +00003245- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3246 exponents for exponents with absolute value < 100. Follows C99
3247 standard. This is a change on Windows, which would use 3 digits.
3248 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3249 so that any alterations it does to the resulting string will be
3250 available in stringlib/formatter.h (for float.__format__).
3251
Eric Smith5a3c1352008-02-19 13:21:56 +00003252- Implemented PEP 3101, Advanced String Formatting. This adds a new
3253 builtin format(); a format() method for str and unicode; a
3254 __format__() method to object, str, unicode, int, long, float, and
3255 datetime; the class string.Formatter; and the C API
3256 PyObject_Format().
3257
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258- Fixed several potential crashes, all caused by specially crafted
3259 __del__ methods exploiting objects in temporarily inconsistent
3260 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003261
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003262- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003263 prevent a possible crash: an Abstract Base Class would try to access
3264 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003265

Georg Brandl3ee81df2008-05-17 18:14:43 +00003303- Patch #1473257: generator objects gain a gi_code attribute. This is
3304 the same object as the func_code attribute of the function that
3305 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003306
Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Issue #1920: "while 0" statements were completely removed by the
3308 compiler, even in the presence of an "else" clause, which is
3309 supposed to be run when the condition is false. Now the compiler
3310 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003311
Guido van Rossumeead05f2008-01-24 18:21:02 +00003312- A few crashers fixed: weakref_in_del.py (issue #1377858);

3319
Georg Brandl3ee81df2008-05-17 18:14:43 +00003320- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003321 several extension methods and modules do not work without unicode
3322 support.
3323

3328
Georg Brandl6caad7d2008-01-26 14:19:22 +00003329- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003330 added.
3331
Christian Heimesc94e2b52008-01-14 04:13:37 +00003332- sys.float_info / PyFloat_GetInfo: The floating point information
3333 object was converted from a dict to a specialized structseq object.
3334
Georg Brandl3ee81df2008-05-17 18:14:43 +00003335- Patch #1816: Added sys.flags structseq. It exposes the status of
3336 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003337
Georg Brandl3ee81df2008-05-17 18:14:43 +00003338- Objects/structseq.c: Implemented new structseq representation. The
3339 patch makes structseqs (e.g. the return value of os.stat) more
3340 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003341
Georg Brandl3ee81df2008-05-17 18:14:43 +00003342- Patch #1700288: added a type attribute cache that caches method
3343 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003344
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003345- Bug #1776: __import__() no longer accepts filenames on any platform.

3351 envvar and sys.dont_write_bytecode attribute. All these can be set
3352 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003353
Georg Brandl3ee81df2008-05-17 18:14:43 +00003354- Improve some exception messages when Windows fails to load an
3355 extension module. Now we get for example '%1 is not a valid Win32
3356 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003363- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003364 and INF. float("nan"), float("inf") and float("-inf") now work on
3365 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003366
Georg Brandl3ee81df2008-05-17 18:14:43 +00003367- Compiler now generates simpler and faster code for dictionary

3413
Georg Brandl5a7eca12010-03-21 19:29:04 +00003414- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003415 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3416 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003417
Georg Brandl3ee81df2008-05-17 18:14:43 +00003418- Issue #1686386: Tuple's tp_repr did not take into account the
3419 possibility of having a self-referential tuple, which is possible
3420 from C code. Nor did object's tp_str consider that a type's tp_str
3421 could do something that could lead to an inifinite recursion.
3422 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3423 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003424
Georg Brandl3ee81df2008-05-17 18:14:43 +00003425- Issue #1164: It was possible to trigger deadlock when using the
3426 'print' statement to write to a file since the GIL was not released
3427 as needed. Now PyObject_Print() does the right thing along with
3428 various tp_print implementations of the built-in types and those in
3429 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003430

Georg Brandl3ee81df2008-05-17 18:14:43 +00003439 PyObject_Call() never calling back out to Python code to trigger
3440 recursion depth updates/checks. Required the creation of a static
3441 RuntimeError instance in case normalizing an exception put the
3442 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00003491- Bug #1683368: The object.__init__() and object.__new__() methods are
3492 now stricter in rejecting excess arguments. The only time when
3493 either allows excess arguments is when it is not overridden and the
3494 other one is. For backwards compatibility, when both are
3495 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003496 warning later). Also, type.__init__() insists on the same signature
3497 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003499- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3500 object to complex using its __complex__() method before falling back
3501 to the __float__() method. Therefore, the functions in the cmath
3502 module now can operate on objects that define a __complex__()
3503 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003521- Bug #1678647: write a newline after printing an exception in any
3522 case, even when converting the value to a string failed.
3523
Georg Brandl871f1bc2007-03-12 13:17:36 +00003524- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525 its argument, if it exists. If not, it will work like before. This
3526 allows customizing the output of dir() in the presence of a
3527 __getattr__().

3537 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003539- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540 makes the filenames the warning module prints much more sensible
3541 when a PYTHONSTARTUP file is used.

3555 sq_ass_slice instead of the sq_slice slot.
3556
Georg Brandl3ee81df2008-05-17 18:14:43 +00003557- When printing an unraisable error, don't print exceptions. before
3558 the name. This duplicates the behavior whening normally printing
3559 exceptions.

Georg Brandl2c1375c2006-10-12 11:27:59 +00003609- Bug #1545497: when given an explicit base, int() did ignore NULs
3610 embedded in the string to convert.
3611
Georg Brandl846f73a2006-10-08 07:11:54 +00003612- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003660 generator expressions (x for x, in ... ) works again. Fixing this
3661 problem required changing the .pyc magic number. This means that
3662 .pyc files generated before 2.5c2 will be regenerated.

4463 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00004464
Georg Brandl3ee81df2008-05-17 18:14:43 +00004465- The implementation of UnicodeError objects has been simplified
4466 (start and end attributes are now stored directly as Py_ssize_t
4467 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004468
Georg Brandl3ee81df2008-05-17 18:14:43 +00004469- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4470 with RFC 3207 and forgets any knowledge obtained from the server not
4471 obtained from the TLS negotiation itself. Patch contributed by Bill
4472 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004473
Georg Brandl3ee81df2008-05-17 18:14:43 +00004474- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004475 that the SMTP.starttls() caller no longer needs to call ehlo()
4476 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004477 does not claim to support starttls. Adds the
4478 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4479 Fenner.

4548 contents before adding elements from the iterable. This fix brings
4549 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00004550
Georg Brandl3ee81df2008-05-17 18:14:43 +00004551- Added wide char functions to msvcrt module: getwch, getwche, putwch

Georg Brandl3ee81df2008-05-17 18:14:43 +00004558- Marshal.dumps() now expects exact type matches for int, long, float,
4559 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4560 silently miscode subclasses of those types. Now, it raises a
4561 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004562

Georg Brandl3ee81df2008-05-17 18:14:43 +00004577 time so that opening a database previously created with the DB_DUP
4578 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4579 opens. Specifically: dictionary assignment to a DB object will
4580 replace all values for a given key when the database allows
4581 duplicate values. DB users should use DB.put(k, v) when they want
4582 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004583

4589 characters with ASCII value less than 32. Also, it correctly quotes
4590 dots only if they occur on a single line, as opposed to the previous
4591 behavior of quoting dots if they are the second character of any
4592 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004593
