679What's New in Python 2.6.1
680==========================
681
682*Release date: 04-Dec-2008*
683
684Core and Builtins
685-----------------
686
687- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
688 interpreter to abort ("Fatal Python error: Could not reset the stack!")
689 instead of throwing a MemoryError.
690
691- Issue #4367: Python would segfault during compiling when the unicodedata
692 module couldn't be imported and \N escapes were present.
693
694- Issue #4348: Some bytearray methods returned that didn't cause any change to
695 the bytearray, returned the same bytearray instead of a copy.
696
697- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
698
699- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
700
701- Issue #4048: The parser module now correctly validates relative imports.
702
703- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
704 exec statement.
705
706- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
707 method does not return iterators for the 4th and 5th items.
708
709- Issue #4209: Enabling unicode_literals and the print_function in the same
710 __future__ import didn't work.
711
712- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
713 returned a path longer than MAX_PATH. (But It's doubtful this code path is
714 really executed because I cannot move to such directory on win2k)
715
716- Issue #4069: When set.remove(element) is used with a set element, the element
717 is temporarily replaced with an equivalent frozenset. But the eventual
718 KeyError would always report the empty frozenset([]) as the missing key. Now
719 it correctly refers to the initial element.
720
721- Fixed C99 style comments in several files. Python is now C89 compatible
722 again.

870
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000871- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
872 PyString_FromFormat or PyErr_Format to display size_t values. The macro
873 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
874 ``printf`` function, whereas PyString_FromFormat has an independent
875 implementation and uses "%zd" on all platforms for size_t values.
876 This makes a difference on win64, where ``printf`` needs "%Id" to display
877 64bit values.

895
Vinay Sajip35e3b032008-09-01 14:33:59 +0000896- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000897 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
898 mechanism. In the process, fix a bug where isinstance() and issubclass(),

994-----------------
995
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000996- Issue #2975: When compiling several extension modules with Visual Studio 2008
997 from the same python interpreter, some environment variables would grow
998 without limit.
999
Benjamin Peterson37346b22008-08-23 20:27:43 +00001000- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1001 exploitation of poor argument checking.
1002
Gerhard Häringef2276b2008-09-12 13:54:06 +00001003- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001037What's New in Python 2.6 beta 3?
1038================================
1039
Barry Warsaw07a4a382008-08-21 01:15:08 +00001040*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001041
1042Core and Builtins
1043-----------------
1044
Guido van Rossumf8402962008-08-20 15:01:50 +00001045- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1046 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1047 extensions do not automatically benefit from the class attribute
1048 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1049 to their tp_flags field if they care. This is a backwards
1050 compatibility feature; in 3.0, all types will use the cache by
1051 default.
1052
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001053- Keyword arguments can now follow starred arguments. (``f(a, *args,
1054 keyword=23)`` is now valid syntax.)
1055
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001056- ctypes function pointers that are COM methods have a boolean True
1057 value again.
1058
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001059- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1060 by denying s# to parse objects that have a releasebuffer procedure,
1061 and introducing s*.
1062
Georg Brandl1e13ea92008-08-11 09:07:59 +00001063- Issue #3537: Fix an assertion failure when an empty but presized dict
1064 object was stored in the freelist.
1065
Mark Dickinsonb6467572008-08-04 21:30:09 +00001066- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1067 ValueError consistently across platforms.
1068
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001069- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1070 (64bit Unix, for example), unichr() would truncate its argument and return
1071 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1072
Neal Norwitze7d8be82008-07-31 17:17:14 +00001073- Apply security patches from Apple.
1074
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001075- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1076 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1077
Antoine Pitrou92f82162008-07-25 22:22:08 +00001078- Issue #1819: function calls with several named parameters are now on
1079 average 35% faster (as measured by pybench).
1080
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001081- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1082 the python debugger steps into a class statement: the free variables (local
1083 variables defined in an outer scope) would be deleted from the outer scope.
1084
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001085- Issue #2620: Overflow checking when allocating or reallocating memory
1086 was not always being done properly in some python types and extension
1087 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1088 all been updated to perform better checks and places in the code that
1089 would previously leak memory on the error path when such an allocation
1090 failed have been fixed.
1091
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001092Library
1093-------
1094
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001095- Issue #3612: Added some missing basic types in ctypes.wintypes.
1096
Benjamin Petersone977ad42008-08-20 01:42:01 +00001097- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1098 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1099
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001100- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1101 version reported by these tools does not necessarily follow the python
1102 version numbering scheme, so the module is less strict when parsing it.
1103
Nick Coghlanf70385a2008-08-18 12:42:46 +00001104- Issue #2235: Added Py3k warnings for types which will become unhashable
1105 under the stricter __hash__ inheritance rules in 3.0. Several types
1106 which did not meet the rules for hash invariants and were already
1107 unhashable in 3.0 have now been explicitly flagged as unhashable in
1108 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1109 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1110
Brett Cannon88f801d2008-08-18 00:46:22 +00001111- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1112 imported into the module but exposed as part of the module's API.
1113
Brett Cannon7b96f072008-08-18 00:41:11 +00001114- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1115
Brett Cannon46225e72008-08-18 00:36:52 +00001116- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1119
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001120- Issue #3575: Incremental decoder's decode function now takes bytearray
1121 by using 's*' instead of 't#'.
1122
Jesus Cea585ad8a2009-07-02 15:37:21 +00001123- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001124 fails unicode conversion on 2nd parameter. (windows only)
1125
Facundo Batista94f243a2008-08-17 03:38:39 +00001126- Issue 2464. urllib2 now supports a malformation in the URL received
1127 in a redirect.
1128
Brett Cannonabe423e2008-08-16 21:47:07 +00001129- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001130 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001131
Facundo Batistaeb90b782008-08-16 14:44:07 +00001132- Issue #2776: fixed small issue when handling an URL with double slash
1133 after a 302 response in the case of not going through a proxy.
1134
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001135- Issue #2676: in the email package, content-type parsing was hanging on
1136 pathological input because of quadratic or exponential behaviour of a
1137 regular expression.
1138
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001139- Issue #3476: binary buffered reading through the new "io" library is now
1140 thread-safe.
1141
Brett Cannonbf3157b2008-08-14 05:00:03 +00001142- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1143 since mimetools itself is deprecated. Because modules are cached, all
1144 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1145
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001146- Issue #3134: shutil referenced undefined WindowsError symbol.
1147
Robert Schuppenies14646332008-08-10 11:01:53 +00001148- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1149 menu entries were not deleted.
1150
Brett Cannon83e81842008-08-09 23:30:55 +00001151- Copied the implementation of reduce() to _functools.reduce() to have a
1152 version that did not raise a DeprecationWarning under -3.
1153
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001154- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1155 a MemoryError rather than silently stop the iteration.
1156
Guido van Rossum59ce9012008-08-09 14:55:34 +00001157- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1158 to _sre.compile() will now be rejected. This should not affect anybody
1159 since the re.compile() function never generates invalid re-bytecode.
1160
Skip Montanaroa032bf42008-08-08 22:52:51 +00001161- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1162 upon first access it can be automatically initialized from the csv file if
1163 it wasn't initialized during instantiation.
1164
Brett Cannon3aa2a492008-08-06 22:28:09 +00001165- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1166 the reload() built-in has been removed.
1167
Brett Cannon7e30b672008-08-04 21:52:25 +00001168- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001169 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1172 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1173 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1174 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

1177 raised an AttributeError.
1178
Benjamin Peterson01a24322008-07-28 23:35:27 +00001179- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001180 asking for a specific length. This problem only affected files opened
1181 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001182
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001183- Issue #3449: Update decimal module to use most recent specification
1184 (v. 1.68) and tests (v. 2.58) from IBM.

1205
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001206- Issue #3394: zipfile.writestr sets external attributes when passed a
1207 file name rather than a ZipInfo instance, so files are extracted with
1208 mode 0600 rather than 000 under Unix.
1209
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001210- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1211 argument in python 2.5, this broke code that subclassed Popen to include its
1212 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001222- Issue #2235: the C API function PyObject_HashNotImplemented and its
1223 interaction with the tp_hash slot (added in 2.6b2) are now documented
1224
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001225- Issue #643841: The language reference now provides more detailed
1226 coverage of the lookup process for special methods. The disclaimers
1227 regarding lack of coverage of new-style classes have also been
1228 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001231What's New in Python 2.6 beta 2?
1232================================
1233
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001234*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001236Core and Builtins
1237-----------------
1238
Georg Brandl3e483f62008-07-16 22:57:41 +00001239- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1240 its methods now allow for items objects that can be converted to
1241 an integer using operator.index().
1242
Mark Dickinson64b7e502008-07-16 09:40:03 +00001243- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1244 produced a ValueError instead of giving the correct float.
1245
Eric Smitha5fa5a22008-07-16 00:11:49 +00001246- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1247 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1248
Mark Dickinson7103aa42008-07-15 19:08:33 +00001249- Issue #3008: the float type has a new instance method 'float.hex'
1250 and a new class method 'float.fromhex' to convert floating-point
1251 numbers to and from hexadecimal strings, respectively.
1252
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001253- Issue #2235: __hash__ is once again inherited by default. To allow
1254 collections.Hashable to remain meaningful in the presence of the
1255 default hash implementation (object.__hash__), it is now possible
1256 to explicit block inheritance of hash by setting __hash__=None at
1257 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1258 level.
1259
Nick Coghlanb028f502008-07-13 14:52:36 +00001260- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1261 the parent module cannot be found while performing an absolute import.
1262 This means that an incorrectly defined __package__ attribute will
1263 now only prevent relative imports in that module rather than causing
1264 all imports from that module to fail.
1265
Nick Coghlan14ff9942008-07-08 14:21:42 +00001266- Issue #2517: Allow unicode messages in Exceptions again by correctly
1267 bypassing the instance dictionary when looking up __unicode__ on
1268 new-style classes.
1269
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001270- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

1282 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00001737 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001738

Georg Brandl3ee81df2008-05-17 18:14:43 +00001799- Issue #1631171: Re-implement the 'warnings' module in C (the
1800 original Python code has been kept as backup). This will allow for
1801 using the 'warning's machinery in such places as the parser where
1802 use of pure Python code is not possible. Both the ``showarning()``
1803 and ``formatwarning()`` gain an optional 'line' argument which is
1804 not called by default for backwards-compatibility reasons. Setting
1805 ``warnings.showwarning()`` to an implementation that lacks support
1806 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001869- Issue #2550: The approach used by client/server code for obtaining
1870 ports to listen on in network-oriented tests has been refined in an
1871 effort to facilitate running multiple instances of the entire
1872 regression test suite in parallel without issue.
1873 test_support.bind_port() has been fixed such that it will always
1874 return a unique port -- which wasn't always the case with the
1875 previous implementation, especially if socket options had been set
1876 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1877 new implementation of bind_port() will actually raise an exception
1878 if it is passed an AF_INET/SOCK_STREAM socket with either the
1879 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1880 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1881 the socket it's been passed. This currently only applies to
1882 Windows. This option prevents any other sockets from binding to the
1883 host/port we've bound to, thus removing the possibility of the
1884 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1885 when a second SOCK_STREAM socket binds and accepts to a host/port
1886 that's already been bound by another socket. The optional preferred
1887 port parameter to bind_port() has been removed. Under no
1888 circumstances should tests be hard coding ports!
1889
1890 test_support.find_unused_port() has also been introduced, which will
1891 pass a temporary socket object to bind_port() in order to obtain an
1892 unused port. The temporary socket object is then closed and
1893 deleted, and the port is returned. This method should only be used
1894 for obtaining an unused port in order to pass to an external program
1895 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1896 a parameter to a server-oriented class that doesn't give you direct
1897 access to the underlying socket used.
1898
1899 Finally, test_support.HOST has been introduced, which should be used
1900 for the host argument of any relevant socket calls (i.e. bind and
1901 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001902
1903 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001904 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001905 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1906 test_asynchat and test_socket_ssl.
1907
Georg Brandl3ee81df2008-05-17 18:14:43 +00001908 It is now possible for multiple instances of the regression test
1909 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002093 optional: it defaults to the traceback of the exception that is
2094 currently being handled (is mandatory to be in the middle of an
2095 exception, otherwise it raises ValueError).

2112
Thomas Heller78b8f442008-03-05 14:53:39 +00002113- The bundled libffi copy is now in sync with the recently released
2114 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002115 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2116 files are used. On all linux systems the --with-system-ffi
2117 configure option defaults to "yes".

2176-----------------
2177
Fred Drakea8ee94b2008-03-01 02:45:07 +00002178- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002179 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002180
Georg Brandlad61bc82008-02-23 15:11:18 +00002181- Issue #2067: file.__exit__() now calls subclasses' close() method.
2182
2183- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002184
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002185- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002186 issue 215555 for a discussion.
2187
Eric Smitha73fbe72008-02-23 03:09:44 +00002188- Added the future_builtins module, which contains hex() and oct().
2189 These are the PEP 3127 version of these functions, designed to be
2190 compatible with the hex() and oct() builtins from Python 3.0. They
2191 differ slightly in their output formats from the existing, unchanged
2192 Python 2.6 builtins. The expected usage of the future_builtins
2193 module is:
2194 from future_builtins import hex, oct
2195
Eric Smith7ef40bf2008-02-20 23:34:22 +00002196- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2197 exponents for exponents with absolute value < 100. Follows C99
2198 standard. This is a change on Windows, which would use 3 digits.
2199 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2200 so that any alterations it does to the resulting string will be
2201 available in stringlib/formatter.h (for float.__format__).
2202
Eric Smith5a3c1352008-02-19 13:21:56 +00002203- Implemented PEP 3101, Advanced String Formatting. This adds a new
2204 builtin format(); a format() method for str and unicode; a
2205 __format__() method to object, str, unicode, int, long, float, and
2206 datetime; the class string.Formatter; and the C API
2207 PyObject_Format().
2208
Georg Brandl3ee81df2008-05-17 18:14:43 +00002209- Fixed several potential crashes, all caused by specially crafted
2210 __del__ methods exploiting objects in temporarily inconsistent
2211 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002212
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002213- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002214 prevent a possible crash: an Abstract Base Class would try to access
2215 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002216
Georg Brandl3ee81df2008-05-17 18:14:43 +00002217- Fixed repr() and str() of complex numbers with infinity or nan as
2218 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002219
Georg Brandl3ee81df2008-05-17 18:14:43 +00002220- Clear all free lists during a gc.collect() of the highest generation
2221 in order to allow pymalloc to free more arenas. Python may give back
2222 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002223
Georg Brandl3ee81df2008-05-17 18:14:43 +00002224- Issue #2045: Fix an infinite recursion triggered when printing a
2225 subclass of collections.defaultdict, if its default_factory is set
2226 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002227
Christian Heimesf75dbef2008-02-08 00:11:31 +00002228- Fixed a minor memory leak in dictobject.c. The content of the free
2229 list was not freed on interpreter shutdown.
2230
Georg Brandl3ee81df2008-05-17 18:14:43 +00002231- Limit free list of method and builtin function objects to 256
2232 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002233
Georg Brandl3ee81df2008-05-17 18:14:43 +00002234- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2235 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002236 to compact the internal free lists of pre-allocted ints and floats.
2237
Georg Brandl3ee81df2008-05-17 18:14:43 +00002238- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2239 calls. Python expected the return type int but the fork familie
2240 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002241
Georg Brandl3ee81df2008-05-17 18:14:43 +00002242- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2243 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002244
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2246 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002247
Georg Brandl3ee81df2008-05-17 18:14:43 +00002248- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2249 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002250
Georg Brandl3ee81df2008-05-17 18:14:43 +00002251- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2252 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002253
Georg Brandl3ee81df2008-05-17 18:14:43 +00002254- Patch #1473257: generator objects gain a gi_code attribute. This is
2255 the same object as the func_code attribute of the function that
2256 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002257
Georg Brandl3ee81df2008-05-17 18:14:43 +00002258- Issue #1920: "while 0" statements were completely removed by the
2259 compiler, even in the presence of an "else" clause, which is
2260 supposed to be run when the condition is false. Now the compiler
2261 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002262
Guido van Rossumeead05f2008-01-24 18:21:02 +00002263- A few crashers fixed: weakref_in_del.py (issue #1377858);
2264 loosing_dict_ref.py (issue #1303614, test67.py);
2265 borrowed_ref_[34].py (not in tracker).
2266
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002267- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002268 suppressed while an extension is loaded by calling SetErrorMode in
2269 dynload_win.c. The error is still reported properly.
2270
Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002272 several extension methods and modules do not work without unicode
2273 support.
2274
Georg Brandl26543b12008-01-21 18:36:51 +00002275- Issue #1882: when compiling code from a string, encoding cookies in the
2276 second line of code were not always recognized correctly.
2277
Georg Brandl14404b62008-01-19 19:27:05 +00002278- Issue #1679: "0x" was taken as a valid integer literal.
2279
Georg Brandl6caad7d2008-01-26 14:19:22 +00002280- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002281 added.
2282
Christian Heimesc94e2b52008-01-14 04:13:37 +00002283- sys.float_info / PyFloat_GetInfo: The floating point information
2284 object was converted from a dict to a specialized structseq object.
2285
Georg Brandl3ee81df2008-05-17 18:14:43 +00002286- Patch #1816: Added sys.flags structseq. It exposes the status of
2287 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002288
Georg Brandl3ee81df2008-05-17 18:14:43 +00002289- Objects/structseq.c: Implemented new structseq representation. The
2290 patch makes structseqs (e.g. the return value of os.stat) more
2291 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002292
Georg Brandl3ee81df2008-05-17 18:14:43 +00002293- Patch #1700288: added a type attribute cache that caches method
2294 accesses, resulting in speedups in heavily object-oriented code.

2302 envvar and sys.dont_write_bytecode attribute. All these can be set
2303 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002304
Georg Brandl3ee81df2008-05-17 18:14:43 +00002305- Improve some exception messages when Windows fails to load an
2306 extension module. Now we get for example '%1 is not a valid Win32
2307 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002308

Christian Heimes0a8143f2007-12-18 23:22:54 +00002314- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002315 and INF. float("nan"), float("inf") and float("-inf") now work on
2316 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002317
Georg Brandl3ee81df2008-05-17 18:14:43 +00002318- Compiler now generates simpler and faster code for dictionary
2319 literals. The oparg for BUILD_MAP now indicates an estimated
2320 dictionary size. There is a new opcode, STORE_MAP, for adding
2321 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002350- Patch #1739468: Directories and zipfiles containing a __main__.py
2351 file can now be directly executed by passing their name to the
2352 interpreter. The directory/zipfile is automatically inserted as the
2353 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002355- Issue #1265: Fix a problem with sys.settrace, if the tracing
2356 function uses a generator expression when at the same time the
2357 executed code is closing a paused generator.

2364
Georg Brandl3ee81df2008-05-17 18:14:43 +00002365- The enumerate() builtin function is no longer bounded to sequences
2366 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2367 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002368
Georg Brandl3ee81df2008-05-17 18:14:43 +00002369- Issue #1686386: Tuple's tp_repr did not take into account the
2370 possibility of having a self-referential tuple, which is possible
2371 from C code. Nor did object's tp_str consider that a type's tp_str
2372 could do something that could lead to an inifinite recursion.
2373 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2374 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002376- Issue #1164: It was possible to trigger deadlock when using the
2377 'print' statement to write to a file since the GIL was not released
2378 as needed. Now PyObject_Print() does the right thing along with
2379 various tp_print implementations of the built-in types and those in
2380 the collections module.

2384 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00002389- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002390 PyObject_Call() never calling back out to Python code to trigger
2391 recursion depth updates/checks. Required the creation of a static
2392 RuntimeError instance in case normalizing an exception put the
2393 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00002409- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002410 __*__ attributes. (Some already existed, e.g., __doc__ and
2411 __name__.)

2417 calls.
2418
Collin Winter62903052007-05-18 23:11:24 +00002419- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002420 "except E as target:". This is to provide forwards compatibility
2421 with Python 3.0.

2427
Vinay Sajip8549ce32007-05-06 17:53:37 +00002428- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002429 setting a plain string, ie don't expand to single letter identifiers.
2430
Raymond Hettinger13936692007-04-11 18:40:58 +00002431- Request #1191699: Slices can now be pickled.
2432
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002433- Request #1193128: str.translate() now allows a None argument for
2434 translations that only remove characters without re-mapping the
2435 remaining characters.
2436
Georg Brandl5cb76c12007-03-21 09:00:39 +00002437- Patch #1682205: a TypeError while unpacking an iterable is no longer

2441
Guido van Rossum143b5642007-03-23 04:58:42 +00002442- Bug #1683368: The object.__init__() and object.__new__() methods are
2443 now stricter in rejecting excess arguments. The only time when
2444 either allows excess arguments is when it is not overridden and the
2445 other one is. For backwards compatibility, when both are
2446 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002447 warning later). Also, type.__init__() insists on the same signature
2448 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002449
Georg Brandl3ee81df2008-05-17 18:14:43 +00002450- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2451 object to complex using its __complex__() method before falling back
2452 to the __float__() method. Therefore, the functions in the cmath
2453 module now can operate on objects that define a __complex__()
2454 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002455
Georg Brandl3ee81df2008-05-17 18:14:43 +00002456- Patch #1623563: allow __class__ assignment for classes with
2457 __slots__. The old and the new class are still required to have the
2458 same slot names.

2465 its type.

2471
Georg Brandl7b9c5552007-03-12 14:30:05 +00002472- Bug #1678647: write a newline after printing an exception in any
2473 case, even when converting the value to a string failed.
2474
Georg Brandl871f1bc2007-03-12 13:17:36 +00002475- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002476 its argument, if it exists. If not, it will work like before. This
2477 allows customizing the output of dir() in the presence of a
2478 __getattr__().

2482
Georg Brandl3ee81df2008-05-17 18:14:43 +00002483- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002486- Patch #1491866: change the complex() constructor to allow
2487 parthensized forms. This means complex(repr(x)) now works instead of
2488 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002489
Georg Brandlaa2321b2007-03-07 00:40:28 +00002490- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002491 makes the filenames the warning module prints much more sensible
2492 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002505- Patch #1674228: when assigning a slice (old-style), check for the
2506 sq_ass_slice instead of the sq_slice slot.
2507
Georg Brandl3ee81df2008-05-17 18:14:43 +00002508- When printing an unraisable error, don't print exceptions. before
2509 the name. This duplicates the behavior whening normally printing
2510 exceptions.

2567
Armin Rigo7ccbca92006-10-04 12:17:45 +00002568- A number of places, including integer negation and absolute value,

3135 TestCase and TestSuite subclasses (not instances) are no longer
3136 accepted in TestSuite.addTest(). This should cause no
3137 incompatibility since it never made sense with ordinary subclasses
3138 -- the failure just occurred later, with a more cumbersome
3139 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003420- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3421 with RFC 3207 and forgets any knowledge obtained from the server not
3422 obtained from the TLS negotiation itself. Patch contributed by Bill
3423 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003424
Georg Brandl3ee81df2008-05-17 18:14:43 +00003425- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003426 that the SMTP.starttls() caller no longer needs to call ehlo()
3427 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003428 does not claim to support starttls. Adds the
3429 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3510 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3511 silently miscode subclasses of those types. Now, it raises a
3512 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003513

Georg Brandl3ee81df2008-05-17 18:14:43 +00003528 time so that opening a database previously created with the DB_DUP
3529 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3530 opens. Specifically: dictionary assignment to a DB object will
3531 replace all values for a given key when the database allows
3532 duplicate values. DB users should use DB.put(k, v) when they want
3533 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003534

3540 characters with ASCII value less than 32. Also, it correctly quotes
3541 dots only if they occur on a single line, as opposed to the previous
3542 behavior of quoting dots if they are the second character of any
3543 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003544

Georg Brandl3ee81df2008-05-17 18:14:43 +00003813 periodic threadstate and signal checking in tight loops. By
3814 default, this option is turned-off. It should only be enabled in
3815 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00003872
Georg Brandl3ee81df2008-05-17 18:14:43 +00003873- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3874 to ``PyTuple_SetItem``, it can be used to populate a brand new

3887
Georg Brandl3ee81df2008-05-17 18:14:43 +00003888- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3889 of w# format code incorrectly truncated the length to an int, even
3890 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3891 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003892
Georg Brandl3ee81df2008-05-17 18:14:43 +00003893- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

Georg Brandl3ee81df2008-05-17 18:14:43 +00003921- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3922 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003923
Georg Brandl3ee81df2008-05-17 18:14:43 +00003924- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003949- Removed the macfs module. It had been deprecated since Python 2.5.
3950 This lead to the deprecation of macostools.touched() as it relied
3951 solely on macfs and was a no-op under OS X.
