80 utf-16 incremental encoders.
81
Ezio Melotti86e5e172010-07-03 05:34:39 +000082- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
83 start byte and the continuation byte(s) are now considered invalid, instead
84 of the number of bytes specified by the start byte.
85 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
86 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
87 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
88 Previous versions returned a single u'\ufffd'.

98 arises from the "Overriding __eq__ blocks inheritance ..." warning
99 when turned into an exception: in this case the exception simply

Mark Dickinsone02c9d22010-05-07 13:23:18 +0000119- Issue #1533: fix inconsistency in range function argument
120 processing: any non-float non-integer argument is now converted to
121 an integer (if possible) using its __int__ method. Previously, only
122 small arguments were treated this way; larger arguments (those whose
123 __int__ was outside the range of a C long) would produce a TypeError.

1726What's New in Python 2.6.1
1727==========================
1728
1729*Release date: 04-Dec-2008*
1730
1731Core and Builtins
1732-----------------
1733
1734- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1735 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1736 instead of throwing a MemoryError.
1737
1738- Issue #4367: Python would segfault during compiling when the unicodedata
1739 module couldn't be imported and \N escapes were present.
1740
1741- Issue #4348: Some bytearray methods returned that didn't cause any change to
1742 the bytearray, returned the same bytearray instead of a copy.
1743
1744- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1745
1746- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1747
1748- Issue #4048: The parser module now correctly validates relative imports.
1749
1750- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1751 exec statement.
1752
1753- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1754 method does not return iterators for the 4th and 5th items.
1755
1756- Issue #4209: Enabling unicode_literals and the print_function in the same
1757 __future__ import didn't work.
1758
1759- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1760 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1761 really executed because I cannot move to such directory on win2k)
1762
1763- Issue #4069: When set.remove(element) is used with a set element, the element
1764 is temporarily replaced with an equivalent frozenset. But the eventual
1765 KeyError would always report the empty frozenset([]) as the missing key. Now
1766 it correctly refers to the initial element.
1767
1768- Fixed C99 style comments in several files. Python is now C89 compatible
1769 again.

1896- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1897 AttributeError instead of RuntimeError, depending in which C API call
1898 exactly the recursion limit is exceeded. Consequently, both exception types
1899 are caught and silenced.

1915
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001916- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1917
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001918- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1919 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1920 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1921 ``printf`` function, whereas PyString_FromFormat has an independent
1922 implementation and uses "%zd" on all platforms for size_t values.
1923 This makes a difference on win64, where ``printf`` needs "%Id" to display
1924 64bit values.
1925
Benjamin Peterson97179b02008-09-09 20:55:01 +00001926- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1927 error.
1928
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001929- Issue #3777: long() applied to a float object now always return a long
1930 object; previously an int would be returned for small values. the __long__
1931 method is allowed to return either an int or a long, but the behaviour of
1932 float objects should not change to respect backward compatibility.
1933
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001934- Issue #3751: str.rpartition would perform a left-partition when called with
1935 a unicode argument.
1936
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001937- Issue #3683: Fix compilation when --without-threads is given.
1938
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001939- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001940 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001941 was correctly parsed but parsing of subsequent arguments failed.
1942
Vinay Sajip35e3b032008-09-01 14:33:59 +00001943- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001944 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1945 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1946 when given a tuple of classes as second argument, were looking up
1947 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1948 type object.
1949
Neal Norwitz18aa3882008-08-24 05:04:52 +00001950- Fix crashes on memory allocation failure found with failmalloc.
1951
1952- Fix memory leaks found with valgrind and update suppressions file.
1953
1954- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1955
1956- Fix problem using wrong name in decimal module reported by pychecker.
1957
Christian Heimes7d4c3172008-08-22 19:47:25 +00001958- Silenced another compiler warning about a used but not defined
1959 function 'stringlib_contains_obj'.

1965 library targets in the Makefile.
1966
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001967- Issue #1204: The configure script now tests for additional libraries
1968 that may be required when linking against readline. This fixes issues
1969 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001992- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001993 return a list or None rather than a custom object.
1994
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001995- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00002019 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2020 for catch_warnings() also led to an improvement in the raising of a
2021 DeprecationWarning related to warnings.warn_explicit().
2022
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002023- The deprecation warnings for the old camelCase threading API were removed.

2090-----------------
2091
Guido van Rossumf8402962008-08-20 15:01:50 +00002092- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2093 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2094 extensions do not automatically benefit from the class attribute
2095 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2096 to their tp_flags field if they care. This is a backwards
2097 compatibility feature; in 3.0, all types will use the cache by
2098 default.
2099
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002100- Keyword arguments can now follow starred arguments. (``f(a, *args,
2101 keyword=23)`` is now valid syntax.)
2102
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002103- ctypes function pointers that are COM methods have a boolean True
2104 value again.
2105
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002106- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2107 by denying s# to parse objects that have a releasebuffer procedure,
2108 and introducing s*.
2109
Georg Brandl1e13ea92008-08-11 09:07:59 +00002110- Issue #3537: Fix an assertion failure when an empty but presized dict
2111 object was stored in the freelist.
2112
Mark Dickinsonb6467572008-08-04 21:30:09 +00002113- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2114 ValueError consistently across platforms.
2115
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002116- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2117 (64bit Unix, for example), unichr() would truncate its argument and return
2118 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2119
Neal Norwitze7d8be82008-07-31 17:17:14 +00002120- Apply security patches from Apple.
2121
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002122- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2123 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2124
Antoine Pitrou92f82162008-07-25 22:22:08 +00002125- Issue #1819: function calls with several named parameters are now on
2126 average 35% faster (as measured by pybench).
2127
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002128- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2129 the python debugger steps into a class statement: the free variables (local
2130 variables defined in an outer scope) would be deleted from the outer scope.
2131
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002132- Issue #2620: Overflow checking when allocating or reallocating memory
2133 was not always being done properly in some python types and extension
2134 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2135 all been updated to perform better checks and places in the code that
2136 would previously leak memory on the error path when such an allocation
2137 failed have been fixed.

2141
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002142- Issue #3612: Added some missing basic types in ctypes.wintypes.
2143
Benjamin Petersone977ad42008-08-20 01:42:01 +00002144- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2145 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2146
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002147- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2148 version reported by these tools does not necessarily follow the python
2149 version numbering scheme, so the module is less strict when parsing it.
2150
Nick Coghlanf70385a2008-08-18 12:42:46 +00002151- Issue #2235: Added Py3k warnings for types which will become unhashable
2152 under the stricter __hash__ inheritance rules in 3.0. Several types
2153 which did not meet the rules for hash invariants and were already
2154 unhashable in 3.0 have now been explicitly flagged as unhashable in
2155 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2156 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2157
Brett Cannon88f801d2008-08-18 00:46:22 +00002158- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2159 imported into the module but exposed as part of the module's API.
2160
Brett Cannon7b96f072008-08-18 00:41:11 +00002161- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2162
Brett Cannon46225e72008-08-18 00:36:52 +00002163- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2284-----------------
2285
Georg Brandl3e483f62008-07-16 22:57:41 +00002286- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2287 its methods now allow for items objects that can be converted to
2288 an integer using operator.index().
2289
Mark Dickinson64b7e502008-07-16 09:40:03 +00002290- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2291 produced a ValueError instead of giving the correct float.
2292
Eric Smitha5fa5a22008-07-16 00:11:49 +00002293- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2294 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2295
Mark Dickinson7103aa42008-07-15 19:08:33 +00002296- Issue #3008: the float type has a new instance method 'float.hex'
2297 and a new class method 'float.fromhex' to convert floating-point
2298 numbers to and from hexadecimal strings, respectively.
2299
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002300- Issue #2235: __hash__ is once again inherited by default. To allow
2301 collections.Hashable to remain meaningful in the presence of the
2302 default hash implementation (object.__hash__), it is now possible
2303 to explicit block inheritance of hash by setting __hash__=None at
2304 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2305 level.
2306
Nick Coghlanb028f502008-07-13 14:52:36 +00002307- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2308 the parent module cannot be found while performing an absolute import.
2309 This means that an incorrectly defined __package__ attribute will
2310 now only prevent relative imports in that module rather than causing
2311 all imports from that module to fail.
2312
Nick Coghlan14ff9942008-07-08 14:21:42 +00002313- Issue #2517: Allow unicode messages in Exceptions again by correctly

2323 another thread's dictionary.
2324
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002325- Issue #3004: Minor change to slice.indices(): the start and stop
2326 arguments are now treated identically, making the behaviour easier
2327 to describe and understand. For example, slice(None, -10,
2328 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2329 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2330 10, -1).
2331
Georg Brandl278fc502008-07-19 12:46:12 +00002332- Issue #3219: Calling a function with repeated keyword arguments,
2333 f(a=2, a=23), would not cause a syntax error. This was a regression
2334 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002372- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2373 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002374 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002375 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002782- On MacOS X it is now possible to install the framework in 64-bit
2783 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002784 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002785
2786 This is controlled by the configure argument ``--with-universal-archs``:
2787
2788 - ``--with-universal-archs=all``: install 4-way universal
2789
2790 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2791
2792 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2793
2794 This option should be used in combination with ``--enable-universalsdk=``.
2795
2796 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 +00002846- Issue #1631171: Re-implement the 'warnings' module in C (the
2847 original Python code has been kept as backup). This will allow for
2848 using the 'warning's machinery in such places as the parser where
2849 use of pure Python code is not possible. Both the ``showarning()``
2850 and ``formatwarning()`` gain an optional 'line' argument which is
2851 not called by default for backwards-compatibility reasons. Setting
2852 ``warnings.showwarning()`` to an implementation that lacks support
2853 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002916- Issue #2550: The approach used by client/server code for obtaining
2917 ports to listen on in network-oriented tests has been refined in an
2918 effort to facilitate running multiple instances of the entire
2919 regression test suite in parallel without issue.
2920 test_support.bind_port() has been fixed such that it will always
2921 return a unique port -- which wasn't always the case with the
2922 previous implementation, especially if socket options had been set
2923 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2924 new implementation of bind_port() will actually raise an exception
2925 if it is passed an AF_INET/SOCK_STREAM socket with either the
2926 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2927 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2928 the socket it's been passed. This currently only applies to
2929 Windows. This option prevents any other sockets from binding to the
2930 host/port we've bound to, thus removing the possibility of the
2931 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2932 when a second SOCK_STREAM socket binds and accepts to a host/port
2933 that's already been bound by another socket. The optional preferred
2934 port parameter to bind_port() has been removed. Under no
2935 circumstances should tests be hard coding ports!
2936
2937 test_support.find_unused_port() has also been introduced, which will
2938 pass a temporary socket object to bind_port() in order to obtain an
2939 unused port. The temporary socket object is then closed and
2940 deleted, and the port is returned. This method should only be used
2941 for obtaining an unused port in order to pass to an external program
2942 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2943 a parameter to a server-oriented class that doesn't give you direct
2944 access to the underlying socket used.
2945
2946 Finally, test_support.HOST has been introduced, which should be used
2947 for the host argument of any relevant socket calls (i.e. bind and
2948 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002949
2950 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002951 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002952 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2953 test_asynchat and test_socket_ssl.
2954
Georg Brandl3ee81df2008-05-17 18:14:43 +00002955 It is now possible for multiple instances of the regression test
2956 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003010- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003011 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3012 Plane. This affected raw unicode literals and the
3013 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3014 this case, like normal unicode literals and the 'unicode-escape'
3015 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00003235- Added the future_builtins module, which contains hex() and oct().
3236 These are the PEP 3127 version of these functions, designed to be
3237 compatible with the hex() and oct() builtins from Python 3.0. They
3238 differ slightly in their output formats from the existing, unchanged
3239 Python 2.6 builtins. The expected usage of the future_builtins
3240 module is:
3241 from future_builtins import hex, oct
3242
Eric Smith7ef40bf2008-02-20 23:34:22 +00003243- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3244 exponents for exponents with absolute value < 100. Follows C99
3245 standard. This is a change on Windows, which would use 3 digits.
3246 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3247 so that any alterations it does to the resulting string will be
3248 available in stringlib/formatter.h (for float.__format__).
3249
Eric Smith5a3c1352008-02-19 13:21:56 +00003250- Implemented PEP 3101, Advanced String Formatting. This adds a new
3251 builtin format(); a format() method for str and unicode; a
3252 __format__() method to object, str, unicode, int, long, float, and
3253 datetime; the class string.Formatter; and the C API
3254 PyObject_Format().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003256- Fixed several potential crashes, all caused by specially crafted
3257 __del__ methods exploiting objects in temporarily inconsistent
3258 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003259
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003260- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003261 prevent a possible crash: an Abstract Base Class would try to access

Georg Brandl3ee81df2008-05-17 18:14:43 +00003267- Clear all free lists during a gc.collect() of the highest generation
3268 in order to allow pymalloc to free more arenas. Python may give back
3269 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003270
Georg Brandl3ee81df2008-05-17 18:14:43 +00003271- Issue #2045: Fix an infinite recursion triggered when printing a
3272 subclass of collections.defaultdict, if its default_factory is set
3273 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003274
Christian Heimesf75dbef2008-02-08 00:11:31 +00003275- Fixed a minor memory leak in dictobject.c. The content of the free

Georg Brandl3ee81df2008-05-17 18:14:43 +00003301- Patch #1473257: generator objects gain a gi_code attribute. This is
3302 the same object as the func_code attribute of the function that
3303 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003304
Georg Brandl3ee81df2008-05-17 18:14:43 +00003305- Issue #1920: "while 0" statements were completely removed by the
3306 compiler, even in the presence of an "else" clause, which is
3307 supposed to be run when the condition is false. Now the compiler
3308 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003309
Guido van Rossumeead05f2008-01-24 18:21:02 +00003310- A few crashers fixed: weakref_in_del.py (issue #1377858);
3311 loosing_dict_ref.py (issue #1303614, test67.py);
3312 borrowed_ref_[34].py (not in tracker).
3313
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003314- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003315 suppressed while an extension is loaded by calling SetErrorMode in
3316 dynload_win.c. The error is still reported properly.
3317
Georg Brandl3ee81df2008-05-17 18:14:43 +00003318- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003319 several extension methods and modules do not work without unicode
3320 support.
3321
Georg Brandl26543b12008-01-21 18:36:51 +00003322- Issue #1882: when compiling code from a string, encoding cookies in the

3326
Georg Brandl6caad7d2008-01-26 14:19:22 +00003327- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003328 added.
3329
Christian Heimesc94e2b52008-01-14 04:13:37 +00003330- sys.float_info / PyFloat_GetInfo: The floating point information
3331 object was converted from a dict to a specialized structseq object.
3332
Georg Brandl3ee81df2008-05-17 18:14:43 +00003333- Patch #1816: Added sys.flags structseq. It exposes the status of
3334 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003335
Georg Brandl3ee81df2008-05-17 18:14:43 +00003336- Objects/structseq.c: Implemented new structseq representation. The
3337 patch makes structseqs (e.g. the return value of os.stat) more
3338 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003339
Georg Brandl3ee81df2008-05-17 18:14:43 +00003340- Patch #1700288: added a type attribute cache that caches method
3341 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003342
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003343- Bug #1776: __import__() no longer accepts filenames on any platform.
3344 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003345
Georg Brandlaed6c662008-01-07 17:25:53 +00003346- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3347
Georg Brandl3ee81df2008-05-17 18:14:43 +00003348- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3349 envvar and sys.dont_write_bytecode attribute. All these can be set
3350 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003351
Georg Brandl3ee81df2008-05-17 18:14:43 +00003352- Improve some exception messages when Windows fails to load an
3353 extension module. Now we get for example '%1 is not a valid Win32
3354 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003355

Christian Heimes0a8143f2007-12-18 23:22:54 +00003361- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003362 and INF. float("nan"), float("inf") and float("-inf") now work on
3363 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003364
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- Compiler now generates simpler and faster code for dictionary
3366 literals. The oparg for BUILD_MAP now indicates an estimated
3367 dictionary size. There is a new opcode, STORE_MAP, for adding
3368 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003402- Issue #1265: Fix a problem with sys.settrace, if the tracing
3403 function uses a generator expression when at the same time the
3404 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003405
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003406- sets and frozensets now have an isdisjoint() method.
3407
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003408- optimize the performance of builtin.sum().

3411
Georg Brandl5a7eca12010-03-21 19:29:04 +00003412- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003413 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3414 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003415
Georg Brandl3ee81df2008-05-17 18:14:43 +00003416- Issue #1686386: Tuple's tp_repr did not take into account the
3417 possibility of having a self-referential tuple, which is possible
3418 from C code. Nor did object's tp_str consider that a type's tp_str
3419 could do something that could lead to an inifinite recursion.
3420 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3421 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003422
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423- Issue #1164: It was possible to trigger deadlock when using the
3424 'print' statement to write to a file since the GIL was not released
3425 as needed. Now PyObject_Print() does the right thing along with
3426 various tp_print implementations of the built-in types and those in
3427 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Issue #1147: Exceptions were directly allowing string exceptions in
3430 their throw() method even though string exceptions no longer
3431 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00003436- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003437 PyObject_Call() never calling back out to Python code to trigger
3438 recursion depth updates/checks. Required the creation of a static
3439 RuntimeError instance in case normalizing an exception put the
3440 recursion check value past its limit. Fixes crashers
3441 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003442

Neal Norwitz0ac60192007-05-27 04:08:54 +00003456- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003457 __*__ attributes. (Some already existed, e.g., __doc__ and
3458 __name__.)

3464 calls.
3465
Collin Winter62903052007-05-18 23:11:24 +00003466- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003467 "except E as target:". This is to provide forwards compatibility
3468 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003475- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003476 setting a plain string, ie don't expand to single letter identifiers.
3477
Raymond Hettinger13936692007-04-11 18:40:58 +00003478- Request #1191699: Slices can now be pickled.
3479
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003480- Request #1193128: str.translate() now allows a None argument for

3482 remaining characters.
3483
Georg Brandl5cb76c12007-03-21 09:00:39 +00003484- Patch #1682205: a TypeError while unpacking an iterable is no longer

3488
Guido van Rossum143b5642007-03-23 04:58:42 +00003489- Bug #1683368: The object.__init__() and object.__new__() methods are
3490 now stricter in rejecting excess arguments. The only time when
3491 either allows excess arguments is when it is not overridden and the
3492 other one is. For backwards compatibility, when both are
3493 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003494 warning later). Also, type.__init__() insists on the same signature
3495 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003497- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3498 object to complex using its __complex__() method before falling back
3499 to the __float__() method. Therefore, the functions in the cmath
3500 module now can operate on objects that define a __complex__()
3501 method.

3521
Georg Brandl871f1bc2007-03-12 13:17:36 +00003522- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003523 its argument, if it exists. If not, it will work like before. This
3524 allows customizing the output of dir() in the presence of a
3525 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003537- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003538 makes the filenames the warning module prints much more sensible
3539 when a PYTHONSTARTUP file is used.

3553 sq_ass_slice instead of the sq_slice slot.
3554
Georg Brandl3ee81df2008-05-17 18:14:43 +00003555- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00003607- Bug #1545497: when given an explicit base, int() did ignore NULs
3608 embedded in the string to convert.
3609
Georg Brandl846f73a2006-10-08 07:11:54 +00003610- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003658 generator expressions (x for x, in ... ) works again. Fixing this
3659 problem required changing the .pyc magic number. This means that
3660 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004463- The implementation of UnicodeError objects has been simplified
4464 (start and end attributes are now stored directly as Py_ssize_t
4465 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004466
Georg Brandl3ee81df2008-05-17 18:14:43 +00004467- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4468 with RFC 3207 and forgets any knowledge obtained from the server not
4469 obtained from the TLS negotiation itself. Patch contributed by Bill
4470 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004471
Georg Brandl3ee81df2008-05-17 18:14:43 +00004472- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004473 that the SMTP.starttls() caller no longer needs to call ehlo()
4474 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004475 does not claim to support starttls. Adds the
4476 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4477 Fenner.

4546 contents before adding elements from the iterable. This fix brings
4547 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00004548
Georg Brandl3ee81df2008-05-17 18:14:43 +00004549- Added wide char functions to msvcrt module: getwch, getwche, putwch

4557 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4558 silently miscode subclasses of those types. Now, it raises a
4559 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004560

Georg Brandl3ee81df2008-05-17 18:14:43 +00004575 time so that opening a database previously created with the DB_DUP
4576 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4577 opens. Specifically: dictionary assignment to a DB object will
4578 replace all values for a given key when the database allows
4579 duplicate values. DB users should use DB.put(k, v) when they want
4580 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004581

4587 characters with ASCII value less than 32. Also, it correctly quotes
4588 dots only if they occur on a single line, as opposed to the previous
4589 behavior of quoting dots if they are the second character of any
4590 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004591
