703What's New in Python 2.6.1
704==========================
705
706*Release date: 04-Dec-2008*
707
708Core and Builtins
709-----------------
710
711- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
712 interpreter to abort ("Fatal Python error: Could not reset the stack!")
713 instead of throwing a MemoryError.
714
715- Issue #4367: Python would segfault during compiling when the unicodedata
716 module couldn't be imported and \N escapes were present.
717
718- Issue #4348: Some bytearray methods returned that didn't cause any change to
719 the bytearray, returned the same bytearray instead of a copy.
720
721- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
722
723- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
724
725- Issue #4048: The parser module now correctly validates relative imports.
726
727- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
728 exec statement.
729
730- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
731 method does not return iterators for the 4th and 5th items.
732
733- Issue #4209: Enabling unicode_literals and the print_function in the same
734 __future__ import didn't work.
735
736- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
737 returned a path longer than MAX_PATH. (But It's doubtful this code path is
738 really executed because I cannot move to such directory on win2k)
739
740- Issue #4069: When set.remove(element) is used with a set element, the element
741 is temporarily replaced with an equivalent frozenset. But the eventual
742 KeyError would always report the empty frozenset([]) as the missing key. Now
743 it correctly refers to the initial element.
744
745- Fixed C99 style comments in several files. Python is now C89 compatible
746 again.

894
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000895- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
896 PyString_FromFormat or PyErr_Format to display size_t values. The macro
897 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
898 ``printf`` function, whereas PyString_FromFormat has an independent

900 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +0000921 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
922 mechanism. In the process, fix a bug where isinstance() and issubclass(),

996 warnings.catch_warnings() along with some API cleanup. Expanding the tests
997 for catch_warnings() also led to an improvement in the raising of a
998 DeprecationWarning related to warnings.warn_explicit().
999

1019
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001020- Issue #2975: When compiling several extension modules with Visual Studio 2008
1021 from the same python interpreter, some environment variables would grow
1022 without limit.
1023
Benjamin Peterson37346b22008-08-23 20:27:43 +00001024- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001061What's New in Python 2.6 beta 3?
1062================================
1063
Barry Warsaw07a4a382008-08-21 01:15:08 +00001064*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001065
1066Core and Builtins
1067-----------------
1068
Guido van Rossumf8402962008-08-20 15:01:50 +00001069- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1070 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1071 extensions do not automatically benefit from the class attribute
1072 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1073 to their tp_flags field if they care. This is a backwards
1074 compatibility feature; in 3.0, all types will use the cache by
1075 default.
1076
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001077- Keyword arguments can now follow starred arguments. (``f(a, *args,
1078 keyword=23)`` is now valid syntax.)
1079
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001080- ctypes function pointers that are COM methods have a boolean True
1081 value again.
1082
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001083- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1084 by denying s# to parse objects that have a releasebuffer procedure,
1085 and introducing s*.
1086
Georg Brandl1e13ea92008-08-11 09:07:59 +00001087- Issue #3537: Fix an assertion failure when an empty but presized dict
1088 object was stored in the freelist.
1089
Mark Dickinsonb6467572008-08-04 21:30:09 +00001090- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1091 ValueError consistently across platforms.
1092
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001093- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1094 (64bit Unix, for example), unichr() would truncate its argument and return
1095 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1096
Neal Norwitze7d8be82008-07-31 17:17:14 +00001097- Apply security patches from Apple.
1098
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001099- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1100 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1101
Antoine Pitrou92f82162008-07-25 22:22:08 +00001102- Issue #1819: function calls with several named parameters are now on
1103 average 35% faster (as measured by pybench).
1104
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001105- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1106 the python debugger steps into a class statement: the free variables (local
1107 variables defined in an outer scope) would be deleted from the outer scope.
1108
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001109- Issue #2620: Overflow checking when allocating or reallocating memory
1110 was not always being done properly in some python types and extension
1111 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1112 all been updated to perform better checks and places in the code that
1113 would previously leak memory on the error path when such an allocation
1114 failed have been fixed.
1115
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001116Library
1117-------
1118

1120
Benjamin Petersone977ad42008-08-20 01:42:01 +00001121- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1122 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1123
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001124- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1125 version reported by these tools does not necessarily follow the python
1126 version numbering scheme, so the module is less strict when parsing it.
1127
Nick Coghlanf70385a2008-08-18 12:42:46 +00001128- Issue #2235: Added Py3k warnings for types which will become unhashable
1129 under the stricter __hash__ inheritance rules in 3.0. Several types
1130 which did not meet the rules for hash invariants and were already
1131 unhashable in 3.0 have now been explicitly flagged as unhashable in
1132 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1133 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1134
Brett Cannon88f801d2008-08-18 00:46:22 +00001135- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1139
Brett Cannon46225e72008-08-18 00:36:52 +00001140- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1143
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001144- Issue #3575: Incremental decoder's decode function now takes bytearray
1145 by using 's*' instead of 't#'.
1146
Jesus Cea585ad8a2009-07-02 15:37:21 +00001147- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001148 fails unicode conversion on 2nd parameter. (windows only)
1149
Facundo Batista94f243a2008-08-17 03:38:39 +00001150- Issue 2464. urllib2 now supports a malformation in the URL received
1151 in a redirect.
1152
Brett Cannonabe423e2008-08-16 21:47:07 +00001153- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001154 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001155
Facundo Batistaeb90b782008-08-16 14:44:07 +00001156- Issue #2776: fixed small issue when handling an URL with double slash
1157 after a 302 response in the case of not going through a proxy.
1158
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001159- Issue #2676: in the email package, content-type parsing was hanging on
1160 pathological input because of quadratic or exponential behaviour of a
1161 regular expression.
1162
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001163- Issue #3476: binary buffered reading through the new "io" library is now
1164 thread-safe.
1165
Brett Cannonbf3157b2008-08-14 05:00:03 +00001166- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1167 since mimetools itself is deprecated. Because modules are cached, all
1168 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1169
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001170- Issue #3134: shutil referenced undefined WindowsError symbol.
1171
Robert Schuppenies14646332008-08-10 11:01:53 +00001172- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1173 menu entries were not deleted.
1174
Brett Cannon83e81842008-08-09 23:30:55 +00001175- Copied the implementation of reduce() to _functools.reduce() to have a
1176 version that did not raise a DeprecationWarning under -3.
1177
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001178- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1179 a MemoryError rather than silently stop the iteration.
1180
Guido van Rossum59ce9012008-08-09 14:55:34 +00001181- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1182 to _sre.compile() will now be rejected. This should not affect anybody
1183 since the re.compile() function never generates invalid re-bytecode.
1184
Skip Montanaroa032bf42008-08-08 22:52:51 +00001185- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00001189- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1190 the reload() built-in has been removed.
1191

Antoine Pitroude781a42008-08-09 12:43:23 +00001204 asking for a specific length. This problem only affected files opened
1205 using the new "io" module, not the built-in open() function.

1232 mode 0600 rather than 000 under Unix.
1233
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001234- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Eric Smitha5fa5a22008-07-16 00:11:49 +00001270- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1271 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1272
Mark Dickinson7103aa42008-07-15 19:08:33 +00001273- Issue #3008: the float type has a new instance method 'float.hex'
1274 and a new class method 'float.fromhex' to convert floating-point
1275 numbers to and from hexadecimal strings, respectively.
1276
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001277- Issue #2235: __hash__ is once again inherited by default. To allow
1278 collections.Hashable to remain meaningful in the presence of the
1279 default hash implementation (object.__hash__), it is now possible
1280 to explicit block inheritance of hash by setting __hash__=None at
1281 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1282 level.
1283
Nick Coghlanb028f502008-07-13 14:52:36 +00001284- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1285 the parent module cannot be found while performing an absolute import.
1286 This means that an incorrectly defined __package__ attribute will
1287 now only prevent relative imports in that module rather than causing
1288 all imports from that module to fail.
1289
Nick Coghlan14ff9942008-07-08 14:21:42 +00001290- Issue #2517: Allow unicode messages in Exceptions again by correctly

1300 another thread's dictionary.
1301
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001302- Issue #3004: Minor change to slice.indices(): the start and stop
1303 arguments are now treated identically, making the behaviour easier
1304 to describe and understand. For example, slice(None, -10,
1305 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1306 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1307 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00001309- Issue #3219: Calling a function with repeated keyword arguments,
1310 f(a=2, a=23), would not cause a syntax error. This was a regression
1311 from 2.4 caused by the switch to the new compiler.

1350 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001351 wrong because the actual transmitted size could differ from the

1826 use of pure Python code is not possible. Both the ``showarning()``
1827 and ``formatwarning()`` gain an optional 'line' argument which is
1828 not called by default for backwards-compatibility reasons. Setting
1829 ``warnings.showwarning()`` to an implementation that lacks support
1830 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001893- Issue #2550: The approach used by client/server code for obtaining
1894 ports to listen on in network-oriented tests has been refined in an
1895 effort to facilitate running multiple instances of the entire
1896 regression test suite in parallel without issue.
1897 test_support.bind_port() has been fixed such that it will always
1898 return a unique port -- which wasn't always the case with the
1899 previous implementation, especially if socket options had been set
1900 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1901 new implementation of bind_port() will actually raise an exception
1902 if it is passed an AF_INET/SOCK_STREAM socket with either the
1903 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1904 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1905 the socket it's been passed. This currently only applies to
1906 Windows. This option prevents any other sockets from binding to the
1907 host/port we've bound to, thus removing the possibility of the
1908 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1909 when a second SOCK_STREAM socket binds and accepts to a host/port
1910 that's already been bound by another socket. The optional preferred
1911 port parameter to bind_port() has been removed. Under no
1912 circumstances should tests be hard coding ports!
1913
1914 test_support.find_unused_port() has also been introduced, which will
1915 pass a temporary socket object to bind_port() in order to obtain an
1916 unused port. The temporary socket object is then closed and
1917 deleted, and the port is returned. This method should only be used
1918 for obtaining an unused port in order to pass to an external program
1919 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1920 a parameter to a server-oriented class that doesn't give you direct
1921 access to the underlying socket used.
1922
1923 Finally, test_support.HOST has been introduced, which should be used
1924 for the host argument of any relevant socket calls (i.e. bind and
1925 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001926
1927 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001928 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001929 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1930 test_asynchat and test_socket_ssl.
1931
Georg Brandl3ee81df2008-05-17 18:14:43 +00001932 It is now possible for multiple instances of the regression test
1933 suite to run in parallel without issue.

2200-----------------
2201
Fred Drakea8ee94b2008-03-01 02:45:07 +00002202- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002203 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002205- Issue #2067: file.__exit__() now calls subclasses' close() method.
2206
2207- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002208
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002209- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002210 issue 215555 for a discussion.
2211
Eric Smitha73fbe72008-02-23 03:09:44 +00002212- Added the future_builtins module, which contains hex() and oct().
2213 These are the PEP 3127 version of these functions, designed to be
2214 compatible with the hex() and oct() builtins from Python 3.0. They
2215 differ slightly in their output formats from the existing, unchanged
2216 Python 2.6 builtins. The expected usage of the future_builtins
2217 module is:
2218 from future_builtins import hex, oct
2219
Eric Smith7ef40bf2008-02-20 23:34:22 +00002220- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2221 exponents for exponents with absolute value < 100. Follows C99
2222 standard. This is a change on Windows, which would use 3 digits.
2223 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2224 so that any alterations it does to the resulting string will be
2225 available in stringlib/formatter.h (for float.__format__).
2226
Eric Smith5a3c1352008-02-19 13:21:56 +00002227- Implemented PEP 3101, Advanced String Formatting. This adds a new
2228 builtin format(); a format() method for str and unicode; a
2229 __format__() method to object, str, unicode, int, long, float, and
2230 datetime; the class string.Formatter; and the C API
2231 PyObject_Format().
2232
Georg Brandl3ee81df2008-05-17 18:14:43 +00002233- Fixed several potential crashes, all caused by specially crafted
2234 __del__ methods exploiting objects in temporarily inconsistent
2235 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002236
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002237- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002238 prevent a possible crash: an Abstract Base Class would try to access
2239 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002240
Georg Brandl3ee81df2008-05-17 18:14:43 +00002241- Fixed repr() and str() of complex numbers with infinity or nan as
2242 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002243
Georg Brandl3ee81df2008-05-17 18:14:43 +00002244- Clear all free lists during a gc.collect() of the highest generation
2245 in order to allow pymalloc to free more arenas. Python may give back
2246 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002247
Georg Brandl3ee81df2008-05-17 18:14:43 +00002248- Issue #2045: Fix an infinite recursion triggered when printing a
2249 subclass of collections.defaultdict, if its default_factory is set
2250 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002251
Christian Heimesf75dbef2008-02-08 00:11:31 +00002252- Fixed a minor memory leak in dictobject.c. The content of the free
2253 list was not freed on interpreter shutdown.
2254
Georg Brandl3ee81df2008-05-17 18:14:43 +00002255- Limit free list of method and builtin function objects to 256
2256 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002257
Georg Brandl3ee81df2008-05-17 18:14:43 +00002258- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2259 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002260 to compact the internal free lists of pre-allocted ints and floats.
2261
Georg Brandl3ee81df2008-05-17 18:14:43 +00002262- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2263 calls. Python expected the return type int but the fork familie
2264 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002265
Georg Brandl3ee81df2008-05-17 18:14:43 +00002266- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2267 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002268
Georg Brandl3ee81df2008-05-17 18:14:43 +00002269- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2270 with the collections.Sequence API.

2273 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002274
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2276 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002277
Georg Brandl3ee81df2008-05-17 18:14:43 +00002278- Patch #1473257: generator objects gain a gi_code attribute. This is
2279 the same object as the func_code attribute of the function that
2280 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002281
Georg Brandl3ee81df2008-05-17 18:14:43 +00002282- Issue #1920: "while 0" statements were completely removed by the
2283 compiler, even in the presence of an "else" clause, which is
2284 supposed to be run when the condition is false. Now the compiler
2285 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002286
Guido van Rossumeead05f2008-01-24 18:21:02 +00002287- A few crashers fixed: weakref_in_del.py (issue #1377858);
2288 loosing_dict_ref.py (issue #1303614, test67.py);
2289 borrowed_ref_[34].py (not in tracker).
2290
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002291- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002292 suppressed while an extension is loaded by calling SetErrorMode in
2293 dynload_win.c. The error is still reported properly.
2294
Georg Brandl3ee81df2008-05-17 18:14:43 +00002295- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002296 several extension methods and modules do not work without unicode
2297 support.
2298
Georg Brandl26543b12008-01-21 18:36:51 +00002299- Issue #1882: when compiling code from a string, encoding cookies in the
2300 second line of code were not always recognized correctly.
2301
Georg Brandl14404b62008-01-19 19:27:05 +00002302- Issue #1679: "0x" was taken as a valid integer literal.
2303
Georg Brandl6caad7d2008-01-26 14:19:22 +00002304- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002305 added.
2306
Christian Heimesc94e2b52008-01-14 04:13:37 +00002307- sys.float_info / PyFloat_GetInfo: The floating point information
2308 object was converted from a dict to a specialized structseq object.
2309
Georg Brandl3ee81df2008-05-17 18:14:43 +00002310- Patch #1816: Added sys.flags structseq. It exposes the status of
2311 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002312
Georg Brandl3ee81df2008-05-17 18:14:43 +00002313- Objects/structseq.c: Implemented new structseq representation. The
2314 patch makes structseqs (e.g. the return value of os.stat) more
2315 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002316
Georg Brandl3ee81df2008-05-17 18:14:43 +00002317- Patch #1700288: added a type attribute cache that caches method
2318 accesses, resulting in speedups in heavily object-oriented code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002329- Improve some exception messages when Windows fails to load an
2330 extension module. Now we get for example '%1 is not a valid Win32
2331 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002332

Georg Brandl3ee81df2008-05-17 18:14:43 +00002342- Compiler now generates simpler and faster code for dictionary
2343 literals. The oparg for BUILD_MAP now indicates an estimated
2344 dictionary size. There is a new opcode, STORE_MAP, for adding
2345 entries to the dictionary.

2388
Georg Brandl3ee81df2008-05-17 18:14:43 +00002389- The enumerate() builtin function is no longer bounded to sequences
2390 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2391 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002392
Georg Brandl3ee81df2008-05-17 18:14:43 +00002393- Issue #1686386: Tuple's tp_repr did not take into account the
2394 possibility of having a self-referential tuple, which is possible
2395 from C code. Nor did object's tp_str consider that a type's tp_str
2396 could do something that could lead to an inifinite recursion.
2397 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2398 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002399
Georg Brandl3ee81df2008-05-17 18:14:43 +00002400- Issue #1164: It was possible to trigger deadlock when using the
2401 'print' statement to write to a file since the GIL was not released
2402 as needed. Now PyObject_Print() does the right thing along with
2403 various tp_print implementations of the built-in types and those in
2404 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00002413- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002414 PyObject_Call() never calling back out to Python code to trigger
2415 recursion depth updates/checks. Required the creation of a static
2416 RuntimeError instance in case normalizing an exception put the
2417 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00002434 __*__ attributes. (Some already existed, e.g., __doc__ and
2435 __name__.)

2442
Collin Winter62903052007-05-18 23:11:24 +00002443- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002444 "except E as target:". This is to provide forwards compatibility
2445 with Python 3.0.

2451
Vinay Sajip8549ce32007-05-06 17:53:37 +00002452- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002453 setting a plain string, ie don't expand to single letter identifiers.
2454
Raymond Hettinger13936692007-04-11 18:40:58 +00002455- Request #1191699: Slices can now be pickled.

2465
Guido van Rossum143b5642007-03-23 04:58:42 +00002466- Bug #1683368: The object.__init__() and object.__new__() methods are
2467 now stricter in rejecting excess arguments. The only time when
2468 either allows excess arguments is when it is not overridden and the
2469 other one is. For backwards compatibility, when both are
2470 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002471 warning later). Also, type.__init__() insists on the same signature
2472 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002473
Georg Brandl3ee81df2008-05-17 18:14:43 +00002474- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2475 object to complex using its __complex__() method before falling back
2476 to the __float__() method. Therefore, the functions in the cmath
2477 module now can operate on objects that define a __complex__()
2478 method.

2495
Georg Brandl7b9c5552007-03-12 14:30:05 +00002496- Bug #1678647: write a newline after printing an exception in any
2497 case, even when converting the value to a string failed.
2498
Georg Brandl871f1bc2007-03-12 13:17:36 +00002499- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002500 its argument, if it exists. If not, it will work like before. This
2501 allows customizing the output of dir() in the presence of a
2502 __getattr__().

2512 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002513
Georg Brandlaa2321b2007-03-07 00:40:28 +00002514- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002515 makes the filenames the warning module prints much more sensible
2516 when a PYTHONSTARTUP file is used.

2531
Georg Brandl3ee81df2008-05-17 18:14:43 +00002532- When printing an unraisable error, don't print exceptions. before

3100
Georg Brandl92a6bae2007-03-13 17:43:32 +00003101- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003102 are set for invalid interpolation sequences that would lead to

3159 TestCase and TestSuite subclasses (not instances) are no longer
3160 accepted in TestSuite.addTest(). This should cause no
3161 incompatibility since it never made sense with ordinary subclasses
3162 -- the failure just occurred later, with a more cumbersome
3163 exception.

3447 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003448
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003450 that the SMTP.starttls() caller no longer needs to call ehlo()
3451 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003452 does not claim to support starttls. Adds the
3453 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00003508- itertools.chain() now has an alternate constructor,

3534 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3535 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00003537

Georg Brandl3ee81df2008-05-17 18:14:43 +00003552 time so that opening a database previously created with the DB_DUP
3553 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3554 opens. Specifically: dictionary assignment to a DB object will
3555 replace all values for a given key when the database allows
3556 duplicate values. DB users should use DB.put(k, v) when they want

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00003836- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837 periodic threadstate and signal checking in tight loops. By
3838 default, this option is turned-off. It should only be enabled in
3839 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00003840

3891
Georg Brandl3ee81df2008-05-17 18:14:43 +00003892- Unified naming convention for free lists and their limits. All free
3893 lists in Object/ are named ``free_list``, the counter ``numfree``
3894 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3895 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003896
Georg Brandl3ee81df2008-05-17 18:14:43 +00003897- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3898 to ``PyTuple_SetItem``, it can be used to populate a brand new
3899 frozenset; but it does not steal a reference to the added item.

3911
Georg Brandl3ee81df2008-05-17 18:14:43 +00003912- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3913 of w# format code incorrectly truncated the length to an int, even
3914 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3915 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003916

Georg Brandl3ee81df2008-05-17 18:14:43 +00003941- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3942 absolute imports. In earlier versions they might have used relative
3943 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003944
Georg Brandl3ee81df2008-05-17 18:14:43 +00003945- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3946 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003947
Georg Brandl3ee81df2008-05-17 18:14:43 +00003948- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003973- Removed the macfs module. It had been deprecated since Python 2.5.
3974 This lead to the deprecation of macostools.touched() as it relied
3975 solely on macfs and was a no-op under OS X.
