683What's New in Python 2.6.1
684==========================
685
686*Release date: 04-Dec-2008*
687
688Core and Builtins
689-----------------
690
691- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
692 interpreter to abort ("Fatal Python error: Could not reset the stack!")
693 instead of throwing a MemoryError.
694
695- Issue #4367: Python would segfault during compiling when the unicodedata
696 module couldn't be imported and \N escapes were present.
697
698- Issue #4348: Some bytearray methods returned that didn't cause any change to
699 the bytearray, returned the same bytearray instead of a copy.
700
701- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
702
703- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
704
705- Issue #4048: The parser module now correctly validates relative imports.
706
707- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
708 exec statement.
709
710- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
711 method does not return iterators for the 4th and 5th items.
712
713- Issue #4209: Enabling unicode_literals and the print_function in the same
714 __future__ import didn't work.
715
716- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
717 returned a path longer than MAX_PATH. (But It's doubtful this code path is
718 really executed because I cannot move to such directory on win2k)
719
720- Issue #4069: When set.remove(element) is used with a set element, the element
721 is temporarily replaced with an equivalent frozenset. But the eventual
722 KeyError would always report the empty frozenset([]) as the missing key. Now
723 it correctly refers to the initial element.
724
725- Fixed C99 style comments in several files. Python is now C89 compatible
726 again.

874
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000875- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
876 PyString_FromFormat or PyErr_Format to display size_t values. The macro
877 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
878 ``printf`` function, whereas PyString_FromFormat has an independent
879 implementation and uses "%zd" on all platforms for size_t values.
880 This makes a difference on win64, where ``printf`` needs "%Id" to display
881 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000901 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
902 mechanism. In the process, fix a bug where isinstance() and issubclass(),

999
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001000- Issue #2975: When compiling several extension modules with Visual Studio 2008
1001 from the same python interpreter, some environment variables would grow
1002 without limit.
1003
Benjamin Peterson37346b22008-08-23 20:27:43 +00001004- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001041What's New in Python 2.6 beta 3?
1042================================
1043
Barry Warsaw07a4a382008-08-21 01:15:08 +00001044*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001045
1046Core and Builtins
1047-----------------
1048
Guido van Rossumf8402962008-08-20 15:01:50 +00001049- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1050 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1051 extensions do not automatically benefit from the class attribute
1052 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1053 to their tp_flags field if they care. This is a backwards
1054 compatibility feature; in 3.0, all types will use the cache by
1055 default.
1056
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001057- Keyword arguments can now follow starred arguments. (``f(a, *args,
1058 keyword=23)`` is now valid syntax.)
1059
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001060- ctypes function pointers that are COM methods have a boolean True
1061 value again.
1062
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001063- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1064 by denying s# to parse objects that have a releasebuffer procedure,
1065 and introducing s*.
1066
Georg Brandl1e13ea92008-08-11 09:07:59 +00001067- Issue #3537: Fix an assertion failure when an empty but presized dict
1068 object was stored in the freelist.
1069
Mark Dickinsonb6467572008-08-04 21:30:09 +00001070- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1071 ValueError consistently across platforms.
1072
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001073- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1074 (64bit Unix, for example), unichr() would truncate its argument and return
1075 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1076
Neal Norwitze7d8be82008-07-31 17:17:14 +00001077- Apply security patches from Apple.
1078
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001079- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1080 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1081
Antoine Pitrou92f82162008-07-25 22:22:08 +00001082- Issue #1819: function calls with several named parameters are now on
1083 average 35% faster (as measured by pybench).
1084
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001085- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1086 the python debugger steps into a class statement: the free variables (local
1087 variables defined in an outer scope) would be deleted from the outer scope.
1088
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001089- Issue #2620: Overflow checking when allocating or reallocating memory
1090 was not always being done properly in some python types and extension
1091 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1092 all been updated to perform better checks and places in the code that
1093 would previously leak memory on the error path when such an allocation
1094 failed have been fixed.
1095
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001096Library
1097-------
1098
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001099- Issue #3612: Added some missing basic types in ctypes.wintypes.
1100
Benjamin Petersone977ad42008-08-20 01:42:01 +00001101- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1102 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1103
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001104- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1105 version reported by these tools does not necessarily follow the python
1106 version numbering scheme, so the module is less strict when parsing it.
1107
Nick Coghlanf70385a2008-08-18 12:42:46 +00001108- Issue #2235: Added Py3k warnings for types which will become unhashable
1109 under the stricter __hash__ inheritance rules in 3.0. Several types
1110 which did not meet the rules for hash invariants and were already
1111 unhashable in 3.0 have now been explicitly flagged as unhashable in
1112 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1113 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1114
Brett Cannon88f801d2008-08-18 00:46:22 +00001115- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1116 imported into the module but exposed as part of the module's API.
1117
Brett Cannon7b96f072008-08-18 00:41:11 +00001118- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1119
Brett Cannon46225e72008-08-18 00:36:52 +00001120- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001122- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1123
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001124- Issue #3575: Incremental decoder's decode function now takes bytearray
1125 by using 's*' instead of 't#'.
1126
Jesus Cea585ad8a2009-07-02 15:37:21 +00001127- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001128 fails unicode conversion on 2nd parameter. (windows only)
1129
Facundo Batista94f243a2008-08-17 03:38:39 +00001130- Issue 2464. urllib2 now supports a malformation in the URL received
1131 in a redirect.
1132
Brett Cannonabe423e2008-08-16 21:47:07 +00001133- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001134 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001135
Facundo Batistaeb90b782008-08-16 14:44:07 +00001136- Issue #2776: fixed small issue when handling an URL with double slash
1137 after a 302 response in the case of not going through a proxy.
1138
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001139- Issue #2676: in the email package, content-type parsing was hanging on
1140 pathological input because of quadratic or exponential behaviour of a
1141 regular expression.
1142
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001143- Issue #3476: binary buffered reading through the new "io" library is now
1144 thread-safe.
1145
Brett Cannonbf3157b2008-08-14 05:00:03 +00001146- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1147 since mimetools itself is deprecated. Because modules are cached, all
1148 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1149
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001150- Issue #3134: shutil referenced undefined WindowsError symbol.
1151
Robert Schuppenies14646332008-08-10 11:01:53 +00001152- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1153 menu entries were not deleted.
1154
Brett Cannon83e81842008-08-09 23:30:55 +00001155- Copied the implementation of reduce() to _functools.reduce() to have a
1156 version that did not raise a DeprecationWarning under -3.
1157
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001158- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1159 a MemoryError rather than silently stop the iteration.
1160
Guido van Rossum59ce9012008-08-09 14:55:34 +00001161- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1162 to _sre.compile() will now be rejected. This should not affect anybody
1163 since the re.compile() function never generates invalid re-bytecode.
1164
Skip Montanaroa032bf42008-08-08 22:52:51 +00001165- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1166 upon first access it can be automatically initialized from the csv file if
1167 it wasn't initialized during instantiation.
1168
Brett Cannon3aa2a492008-08-06 22:28:09 +00001169- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1170 the reload() built-in has been removed.
1171
Brett Cannon7e30b672008-08-04 21:52:25 +00001172- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001173 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1181 raised an AttributeError.
1182
Benjamin Peterson01a24322008-07-28 23:35:27 +00001183- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001184 asking for a specific length. This problem only affected files opened
1185 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001186

1209
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001210- Issue #3394: zipfile.writestr sets external attributes when passed a
1211 file name rather than a ZipInfo instance, so files are extracted with
1212 mode 0600 rather than 000 under Unix.
1213
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001214- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1215 argument in python 2.5, this broke code that subclassed Popen to include its

1230 coverage of the lookup process for special methods. The disclaimers
1231 regarding lack of coverage of new-style classes have also been
1232 removed, since the coverage is now fairly reasonable.

1237
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001238*Release date: 17-Jul-2008*

1241-----------------
1242
Georg Brandl3e483f62008-07-16 22:57:41 +00001243- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1244 its methods now allow for items objects that can be converted to
1245 an integer using operator.index().
1246
Mark Dickinson64b7e502008-07-16 09:40:03 +00001247- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1248 produced a ValueError instead of giving the correct float.
1249
Eric Smitha5fa5a22008-07-16 00:11:49 +00001250- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1251 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1252
Mark Dickinson7103aa42008-07-15 19:08:33 +00001253- Issue #3008: the float type has a new instance method 'float.hex'
1254 and a new class method 'float.fromhex' to convert floating-point
1255 numbers to and from hexadecimal strings, respectively.
1256
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001257- Issue #2235: __hash__ is once again inherited by default. To allow
1258 collections.Hashable to remain meaningful in the presence of the
1259 default hash implementation (object.__hash__), it is now possible
1260 to explicit block inheritance of hash by setting __hash__=None at
1261 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1262 level.
1263
Nick Coghlanb028f502008-07-13 14:52:36 +00001264- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1265 the parent module cannot be found while performing an absolute import.
1266 This means that an incorrectly defined __package__ attribute will
1267 now only prevent relative imports in that module rather than causing
1268 all imports from that module to fail.
1269
Nick Coghlan14ff9942008-07-08 14:21:42 +00001270- Issue #2517: Allow unicode messages in Exceptions again by correctly
1271 bypassing the instance dictionary when looking up __unicode__ on
1272 new-style classes.
1273

1286 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00001741 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001742

Georg Brandl3ee81df2008-05-17 18:14:43 +00001803- Issue #1631171: Re-implement the 'warnings' module in C (the
1804 original Python code has been kept as backup). This will allow for
1805 using the 'warning's machinery in such places as the parser where
1806 use of pure Python code is not possible. Both the ``showarning()``
1807 and ``formatwarning()`` gain an optional 'line' argument which is
1808 not called by default for backwards-compatibility reasons. Setting
1809 ``warnings.showwarning()`` to an implementation that lacks support
1810 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001873- Issue #2550: The approach used by client/server code for obtaining
1874 ports to listen on in network-oriented tests has been refined in an
1875 effort to facilitate running multiple instances of the entire
1876 regression test suite in parallel without issue.
1877 test_support.bind_port() has been fixed such that it will always
1878 return a unique port -- which wasn't always the case with the
1879 previous implementation, especially if socket options had been set
1880 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1881 new implementation of bind_port() will actually raise an exception
1882 if it is passed an AF_INET/SOCK_STREAM socket with either the
1883 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1884 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1885 the socket it's been passed. This currently only applies to
1886 Windows. This option prevents any other sockets from binding to the
1887 host/port we've bound to, thus removing the possibility of the
1888 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1889 when a second SOCK_STREAM socket binds and accepts to a host/port
1890 that's already been bound by another socket. The optional preferred
1891 port parameter to bind_port() has been removed. Under no
1892 circumstances should tests be hard coding ports!
1893
1894 test_support.find_unused_port() has also been introduced, which will
1895 pass a temporary socket object to bind_port() in order to obtain an
1896 unused port. The temporary socket object is then closed and
1897 deleted, and the port is returned. This method should only be used
1898 for obtaining an unused port in order to pass to an external program
1899 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1900 a parameter to a server-oriented class that doesn't give you direct
1901 access to the underlying socket used.
1902
1903 Finally, test_support.HOST has been introduced, which should be used
1904 for the host argument of any relevant socket calls (i.e. bind and
1905 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001906
1907 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001908 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001909 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1910 test_asynchat and test_socket_ssl.
1911
Georg Brandl3ee81df2008-05-17 18:14:43 +00001912 It is now possible for multiple instances of the regression test
1913 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002097 optional: it defaults to the traceback of the exception that is
2098 currently being handled (is mandatory to be in the middle of an
2099 exception, otherwise it raises ValueError).

2116
Thomas Heller78b8f442008-03-05 14:53:39 +00002117- The bundled libffi copy is now in sync with the recently released
2118 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002119 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2120 files are used. On all linux systems the --with-system-ffi
2121 configure option defaults to "yes".

2180-----------------
2181
Fred Drakea8ee94b2008-03-01 02:45:07 +00002182- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002183 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002184
Georg Brandlad61bc82008-02-23 15:11:18 +00002185- Issue #2067: file.__exit__() now calls subclasses' close() method.
2186
2187- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002188
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002189- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002190 issue 215555 for a discussion.
2191
Eric Smitha73fbe72008-02-23 03:09:44 +00002192- Added the future_builtins module, which contains hex() and oct().
2193 These are the PEP 3127 version of these functions, designed to be
2194 compatible with the hex() and oct() builtins from Python 3.0. They
2195 differ slightly in their output formats from the existing, unchanged
2196 Python 2.6 builtins. The expected usage of the future_builtins
2197 module is:
2198 from future_builtins import hex, oct
2199
Eric Smith7ef40bf2008-02-20 23:34:22 +00002200- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2201 exponents for exponents with absolute value < 100. Follows C99
2202 standard. This is a change on Windows, which would use 3 digits.
2203 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2204 so that any alterations it does to the resulting string will be
2205 available in stringlib/formatter.h (for float.__format__).
2206
Eric Smith5a3c1352008-02-19 13:21:56 +00002207- Implemented PEP 3101, Advanced String Formatting. This adds a new
2208 builtin format(); a format() method for str and unicode; a
2209 __format__() method to object, str, unicode, int, long, float, and
2210 datetime; the class string.Formatter; and the C API
2211 PyObject_Format().
2212
Georg Brandl3ee81df2008-05-17 18:14:43 +00002213- Fixed several potential crashes, all caused by specially crafted
2214 __del__ methods exploiting objects in temporarily inconsistent
2215 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002216
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002217- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218 prevent a possible crash: an Abstract Base Class would try to access
2219 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002220
Georg Brandl3ee81df2008-05-17 18:14:43 +00002221- Fixed repr() and str() of complex numbers with infinity or nan as
2222 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002223
Georg Brandl3ee81df2008-05-17 18:14:43 +00002224- Clear all free lists during a gc.collect() of the highest generation
2225 in order to allow pymalloc to free more arenas. Python may give back
2226 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002227
Georg Brandl3ee81df2008-05-17 18:14:43 +00002228- Issue #2045: Fix an infinite recursion triggered when printing a
2229 subclass of collections.defaultdict, if its default_factory is set
2230 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002231
Christian Heimesf75dbef2008-02-08 00:11:31 +00002232- Fixed a minor memory leak in dictobject.c. The content of the free
2233 list was not freed on interpreter shutdown.
2234
Georg Brandl3ee81df2008-05-17 18:14:43 +00002235- Limit free list of method and builtin function objects to 256
2236 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002237
Georg Brandl3ee81df2008-05-17 18:14:43 +00002238- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2239 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002240 to compact the internal free lists of pre-allocted ints and floats.
2241
Georg Brandl3ee81df2008-05-17 18:14:43 +00002242- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2243 calls. Python expected the return type int but the fork familie
2244 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002245
Georg Brandl3ee81df2008-05-17 18:14:43 +00002246- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2247 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002248
Georg Brandl3ee81df2008-05-17 18:14:43 +00002249- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2250 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002251
Georg Brandl3ee81df2008-05-17 18:14:43 +00002252- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2253 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002254
Georg Brandl3ee81df2008-05-17 18:14:43 +00002255- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2256 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002257
Georg Brandl3ee81df2008-05-17 18:14:43 +00002258- Patch #1473257: generator objects gain a gi_code attribute. This is
2259 the same object as the func_code attribute of the function that
2260 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002261
Georg Brandl3ee81df2008-05-17 18:14:43 +00002262- Issue #1920: "while 0" statements were completely removed by the
2263 compiler, even in the presence of an "else" clause, which is
2264 supposed to be run when the condition is false. Now the compiler
2265 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002266
Guido van Rossumeead05f2008-01-24 18:21:02 +00002267- A few crashers fixed: weakref_in_del.py (issue #1377858);
2268 loosing_dict_ref.py (issue #1303614, test67.py);
2269 borrowed_ref_[34].py (not in tracker).
2270
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002271- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002272 suppressed while an extension is loaded by calling SetErrorMode in
2273 dynload_win.c. The error is still reported properly.
2274
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002276 several extension methods and modules do not work without unicode
2277 support.
2278
Georg Brandl26543b12008-01-21 18:36:51 +00002279- Issue #1882: when compiling code from a string, encoding cookies in the
2280 second line of code were not always recognized correctly.
2281
Georg Brandl14404b62008-01-19 19:27:05 +00002282- Issue #1679: "0x" was taken as a valid integer literal.
2283
Georg Brandl6caad7d2008-01-26 14:19:22 +00002284- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002285 added.
2286
Christian Heimesc94e2b52008-01-14 04:13:37 +00002287- sys.float_info / PyFloat_GetInfo: The floating point information
2288 object was converted from a dict to a specialized structseq object.
2289
Georg Brandl3ee81df2008-05-17 18:14:43 +00002290- Patch #1816: Added sys.flags structseq. It exposes the status of
2291 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002292
Georg Brandl3ee81df2008-05-17 18:14:43 +00002293- Objects/structseq.c: Implemented new structseq representation. The
2294 patch makes structseqs (e.g. the return value of os.stat) more
2295 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002296
Georg Brandl3ee81df2008-05-17 18:14:43 +00002297- Patch #1700288: added a type attribute cache that caches method
2298 accesses, resulting in speedups in heavily object-oriented code.

2306 envvar and sys.dont_write_bytecode attribute. All these can be set
2307 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002308
Georg Brandl3ee81df2008-05-17 18:14:43 +00002309- Improve some exception messages when Windows fails to load an
2310 extension module. Now we get for example '%1 is not a valid Win32
2311 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002312

Christian Heimes0a8143f2007-12-18 23:22:54 +00002318- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002319 and INF. float("nan"), float("inf") and float("-inf") now work on
2320 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002321
Georg Brandl3ee81df2008-05-17 18:14:43 +00002322- Compiler now generates simpler and faster code for dictionary
2323 literals. The oparg for BUILD_MAP now indicates an estimated
2324 dictionary size. There is a new opcode, STORE_MAP, for adding
2325 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002354- Patch #1739468: Directories and zipfiles containing a __main__.py
2355 file can now be directly executed by passing their name to the
2356 interpreter. The directory/zipfile is automatically inserted as the
2357 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002359- Issue #1265: Fix a problem with sys.settrace, if the tracing
2360 function uses a generator expression when at the same time the
2361 executed code is closing a paused generator.

2368
Georg Brandl3ee81df2008-05-17 18:14:43 +00002369- The enumerate() builtin function is no longer bounded to sequences
2370 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2371 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002372
Georg Brandl3ee81df2008-05-17 18:14:43 +00002373- Issue #1686386: Tuple's tp_repr did not take into account the
2374 possibility of having a self-referential tuple, which is possible
2375 from C code. Nor did object's tp_str consider that a type's tp_str
2376 could do something that could lead to an inifinite recursion.
2377 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2378 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002379
Georg Brandl3ee81df2008-05-17 18:14:43 +00002380- Issue #1164: It was possible to trigger deadlock when using the
2381 'print' statement to write to a file since the GIL was not released
2382 as needed. Now PyObject_Print() does the right thing along with
2383 various tp_print implementations of the built-in types and those in
2384 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002386- Issue #1147: Exceptions were directly allowing string exceptions in
2387 their throw() method even though string exceptions no longer
2388 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00002393- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002394 PyObject_Call() never calling back out to Python code to trigger
2395 recursion depth updates/checks. Required the creation of a static
2396 RuntimeError instance in case normalizing an exception put the
2397 recursion check value past its limit. Fixes crashers
2398 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002413- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002414 __*__ attributes. (Some already existed, e.g., __doc__ and
2415 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002416
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002417- Add -3 option to the interpreter to warn about features that are
2418 deprecated and will be changed/removed in Python 3.0.
2419
Georg Brandl2134e752007-05-21 20:34:16 +00002420- Patch #1686487: you can now pass any mapping after '**' in function
2421 calls.
2422
Collin Winter62903052007-05-18 23:11:24 +00002423- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002424 "except E as target:". This is to provide forwards compatibility
2425 with Python 3.0.

2431
Vinay Sajip8549ce32007-05-06 17:53:37 +00002432- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002433 setting a plain string, ie don't expand to single letter identifiers.
2434
Raymond Hettinger13936692007-04-11 18:40:58 +00002435- Request #1191699: Slices can now be pickled.
2436
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002437- Request #1193128: str.translate() now allows a None argument for
2438 translations that only remove characters without re-mapping the
2439 remaining characters.
2440
Georg Brandl5cb76c12007-03-21 09:00:39 +00002441- Patch #1682205: a TypeError while unpacking an iterable is no longer

2445
Guido van Rossum143b5642007-03-23 04:58:42 +00002446- Bug #1683368: The object.__init__() and object.__new__() methods are
2447 now stricter in rejecting excess arguments. The only time when
2448 either allows excess arguments is when it is not overridden and the
2449 other one is. For backwards compatibility, when both are
2450 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002451 warning later). Also, type.__init__() insists on the same signature
2452 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002453
Georg Brandl3ee81df2008-05-17 18:14:43 +00002454- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2455 object to complex using its __complex__() method before falling back
2456 to the __float__() method. Therefore, the functions in the cmath
2457 module now can operate on objects that define a __complex__()
2458 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002459
Georg Brandl3ee81df2008-05-17 18:14:43 +00002460- Patch #1623563: allow __class__ assignment for classes with
2461 __slots__. The old and the new class are still required to have the
2462 same slot names.

2468 ``object.__reduce_ex__()`` is called with an object that is faking
2469 its type.

2475
Georg Brandl7b9c5552007-03-12 14:30:05 +00002476- Bug #1678647: write a newline after printing an exception in any
2477 case, even when converting the value to a string failed.
2478
Georg Brandl871f1bc2007-03-12 13:17:36 +00002479- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002480 its argument, if it exists. If not, it will work like before. This
2481 allows customizing the output of dir() in the presence of a
2482 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00002484- Patch #922167: Python no longer segfaults when faced with infinitely
2485 self-recursive reload() calls (as reported by bug #742342).
2486
Georg Brandl3ee81df2008-05-17 18:14:43 +00002487- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002490- Patch #1491866: change the complex() constructor to allow
2491 parthensized forms. This means complex(repr(x)) now works instead of
2492 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002493
Georg Brandlaa2321b2007-03-07 00:40:28 +00002494- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002495 makes the filenames the warning module prints much more sensible
2496 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002497

Georg Brandl0fca97a2007-03-05 22:28:08 +00002509- Patch #1674228: when assigning a slice (old-style), check for the
2510 sq_ass_slice instead of the sq_slice slot.
2511
Georg Brandl3ee81df2008-05-17 18:14:43 +00002512- When printing an unraisable error, don't print exceptions. before
2513 the name. This duplicates the behavior whening normally printing
2514 exceptions.

2571
Armin Rigo7ccbca92006-10-04 12:17:45 +00002572- A number of places, including integer negation and absolute value,

3142 -- the failure just occurred later, with a more cumbersome
3143 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003424- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3425 with RFC 3207 and forgets any knowledge obtained from the server not
3426 obtained from the TLS negotiation itself. Patch contributed by Bill
3427 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003430 that the SMTP.starttls() caller no longer needs to call ehlo()
3431 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003432 does not claim to support starttls. Adds the
3433 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3434 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003488- itertools.chain() now has an alternate constructor,

3514 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3515 silently miscode subclasses of those types. Now, it raises a
3516 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003517

Georg Brandl3ee81df2008-05-17 18:14:43 +00003532 time so that opening a database previously created with the DB_DUP
3533 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3534 opens. Specifically: dictionary assignment to a DB object will
3535 replace all values for a given key when the database allows
3536 duplicate values. DB users should use DB.put(k, v) when they want
3537 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003538

3544 characters with ASCII value less than 32. Also, it correctly quotes
3545 dots only if they occur on a single line, as opposed to the previous
3546 behavior of quoting dots if they are the second character of any
3547 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003548

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00003816- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00003817 periodic threadstate and signal checking in tight loops. By
3818 default, this option is turned-off. It should only be enabled in
3819 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00003876
Georg Brandl3ee81df2008-05-17 18:14:43 +00003877- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3878 to ``PyTuple_SetItem``, it can be used to populate a brand new

3891
Georg Brandl3ee81df2008-05-17 18:14:43 +00003892- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3893 of w# format code incorrectly truncated the length to an int, even
3894 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3895 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003896
Georg Brandl3ee81df2008-05-17 18:14:43 +00003897- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

Georg Brandl3ee81df2008-05-17 18:14:43 +00003925- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3926 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003927
Georg Brandl3ee81df2008-05-17 18:14:43 +00003928- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003953- Removed the macfs module. It had been deprecated since Python 2.5.
3954 This lead to the deprecation of macostools.touched() as it relied
