673What's New in Python 2.6.1
674==========================
675
676*Release date: 04-Dec-2008*
677
678Core and Builtins
679-----------------
680
681- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
682 interpreter to abort ("Fatal Python error: Could not reset the stack!")
683 instead of throwing a MemoryError.
684
685- Issue #4367: Python would segfault during compiling when the unicodedata
686 module couldn't be imported and \N escapes were present.
687
688- Issue #4348: Some bytearray methods returned that didn't cause any change to
689 the bytearray, returned the same bytearray instead of a copy.
690
691- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
692
693- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
694
695- Issue #4048: The parser module now correctly validates relative imports.
696
697- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
698 exec statement.
699
700- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
701 method does not return iterators for the 4th and 5th items.
702
703- Issue #4209: Enabling unicode_literals and the print_function in the same
704 __future__ import didn't work.
705
706- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
707 returned a path longer than MAX_PATH. (But It's doubtful this code path is
708 really executed because I cannot move to such directory on win2k)
709
710- Issue #4069: When set.remove(element) is used with a set element, the element
711 is temporarily replaced with an equivalent frozenset. But the eventual
712 KeyError would always report the empty frozenset([]) as the missing key. Now
713 it correctly refers to the initial element.
714
715- Fixed C99 style comments in several files. Python is now C89 compatible
716 again.

864
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000865- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
866 PyString_FromFormat or PyErr_Format to display size_t values. The macro
867 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
868 ``printf`` function, whereas PyString_FromFormat has an independent
869 implementation and uses "%zd" on all platforms for size_t values.
870 This makes a difference on win64, where ``printf`` needs "%Id" to display
871 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000891 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
892 mechanism. In the process, fix a bug where isinstance() and issubclass(),

988-----------------
989
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000990- Issue #2975: When compiling several extension modules with Visual Studio 2008
991 from the same python interpreter, some environment variables would grow
992 without limit.
993
Benjamin Peterson37346b22008-08-23 20:27:43 +0000994- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1010 wrapper for warnings.catch_warnings() that makes it easier to check
1011 that expected warning messages are being reported.
1012
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001013- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001031What's New in Python 2.6 beta 3?
1032================================
1033
Barry Warsaw07a4a382008-08-21 01:15:08 +00001034*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001035
1036Core and Builtins
1037-----------------
1038
Guido van Rossumf8402962008-08-20 15:01:50 +00001039- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1040 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1041 extensions do not automatically benefit from the class attribute
1042 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1043 to their tp_flags field if they care. This is a backwards
1044 compatibility feature; in 3.0, all types will use the cache by
1045 default.
1046
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001047- Keyword arguments can now follow starred arguments. (``f(a, *args,
1048 keyword=23)`` is now valid syntax.)
1049
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001050- ctypes function pointers that are COM methods have a boolean True
1051 value again.
1052
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001053- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1054 by denying s# to parse objects that have a releasebuffer procedure,
1055 and introducing s*.
1056
Georg Brandl1e13ea92008-08-11 09:07:59 +00001057- Issue #3537: Fix an assertion failure when an empty but presized dict
1058 object was stored in the freelist.
1059
Mark Dickinsonb6467572008-08-04 21:30:09 +00001060- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1061 ValueError consistently across platforms.
1062
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001063- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1064 (64bit Unix, for example), unichr() would truncate its argument and return
1065 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1066
Neal Norwitze7d8be82008-07-31 17:17:14 +00001067- Apply security patches from Apple.
1068
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001069- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1070 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1071
Antoine Pitrou92f82162008-07-25 22:22:08 +00001072- Issue #1819: function calls with several named parameters are now on
1073 average 35% faster (as measured by pybench).
1074
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001075- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1076 the python debugger steps into a class statement: the free variables (local
1077 variables defined in an outer scope) would be deleted from the outer scope.
1078
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001079- Issue #2620: Overflow checking when allocating or reallocating memory
1080 was not always being done properly in some python types and extension
1081 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1082 all been updated to perform better checks and places in the code that
1083 would previously leak memory on the error path when such an allocation
1084 failed have been fixed.
1085
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001086Library
1087-------
1088
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001089- Issue #3612: Added some missing basic types in ctypes.wintypes.
1090
Benjamin Petersone977ad42008-08-20 01:42:01 +00001091- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1092 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1093
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001094- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1095 version reported by these tools does not necessarily follow the python
1096 version numbering scheme, so the module is less strict when parsing it.
1097
Nick Coghlanf70385a2008-08-18 12:42:46 +00001098- Issue #2235: Added Py3k warnings for types which will become unhashable
1099 under the stricter __hash__ inheritance rules in 3.0. Several types
1100 which did not meet the rules for hash invariants and were already
1101 unhashable in 3.0 have now been explicitly flagged as unhashable in
1102 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1103 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1104
Brett Cannon88f801d2008-08-18 00:46:22 +00001105- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1106 imported into the module but exposed as part of the module's API.
1107
Brett Cannon7b96f072008-08-18 00:41:11 +00001108- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1109
Brett Cannon46225e72008-08-18 00:36:52 +00001110- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001112- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1113
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001114- Issue #3575: Incremental decoder's decode function now takes bytearray
1115 by using 's*' instead of 't#'.
1116
Jesus Cea585ad8a2009-07-02 15:37:21 +00001117- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001118 fails unicode conversion on 2nd parameter. (windows only)
1119
Facundo Batista94f243a2008-08-17 03:38:39 +00001120- Issue 2464. urllib2 now supports a malformation in the URL received
1121 in a redirect.
1122
Brett Cannonabe423e2008-08-16 21:47:07 +00001123- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001124 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001125
Facundo Batistaeb90b782008-08-16 14:44:07 +00001126- Issue #2776: fixed small issue when handling an URL with double slash
1127 after a 302 response in the case of not going through a proxy.
1128
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001129- Issue #2676: in the email package, content-type parsing was hanging on
1130 pathological input because of quadratic or exponential behaviour of a
1131 regular expression.
1132
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001133- Issue #3476: binary buffered reading through the new "io" library is now
1134 thread-safe.
1135
Brett Cannonbf3157b2008-08-14 05:00:03 +00001136- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1137 since mimetools itself is deprecated. Because modules are cached, all
1138 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1139
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001140- Issue #3134: shutil referenced undefined WindowsError symbol.
1141
Robert Schuppenies14646332008-08-10 11:01:53 +00001142- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1143 menu entries were not deleted.
1144
Brett Cannon83e81842008-08-09 23:30:55 +00001145- Copied the implementation of reduce() to _functools.reduce() to have a
1146 version that did not raise a DeprecationWarning under -3.
1147
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001148- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1149 a MemoryError rather than silently stop the iteration.
1150
Guido van Rossum59ce9012008-08-09 14:55:34 +00001151- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1152 to _sre.compile() will now be rejected. This should not affect anybody
1153 since the re.compile() function never generates invalid re-bytecode.
1154
Skip Montanaroa032bf42008-08-08 22:52:51 +00001155- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1156 upon first access it can be automatically initialized from the csv file if
1157 it wasn't initialized during instantiation.
1158
Brett Cannon3aa2a492008-08-06 22:28:09 +00001159- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1160 the reload() built-in has been removed.
1161
Brett Cannon7e30b672008-08-04 21:52:25 +00001162- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001163 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1166 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1167 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1168 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

1171 raised an AttributeError.
1172
Benjamin Peterson01a24322008-07-28 23:35:27 +00001173- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001174 asking for a specific length. This problem only affected files opened
1175 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001176
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001177- Issue #3449: Update decimal module to use most recent specification
1178 (v. 1.68) and tests (v. 2.58) from IBM.
1179

1188
1189- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1190 invalid arguments.
1191

1199
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001200- Issue #3394: zipfile.writestr sets external attributes when passed a
1201 file name rather than a ZipInfo instance, so files are extracted with
1202 mode 0600 rather than 000 under Unix.
1203
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001204- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1205 argument in python 2.5, this broke code that subclassed Popen to include its
1206 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001216- Issue #2235: the C API function PyObject_HashNotImplemented and its
1217 interaction with the tp_hash slot (added in 2.6b2) are now documented
1218
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001219- Issue #643841: The language reference now provides more detailed
1220 coverage of the lookup process for special methods. The disclaimers
1221 regarding lack of coverage of new-style classes have also been
1222 removed, since the coverage is now fairly reasonable.

1226================================
1227
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001228*Release date: 17-Jul-2008*

1231-----------------
1232
Georg Brandl3e483f62008-07-16 22:57:41 +00001233- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1234 its methods now allow for items objects that can be converted to
1235 an integer using operator.index().
1236
Mark Dickinson64b7e502008-07-16 09:40:03 +00001237- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1238 produced a ValueError instead of giving the correct float.
1239
Eric Smitha5fa5a22008-07-16 00:11:49 +00001240- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1241 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1242
Mark Dickinson7103aa42008-07-15 19:08:33 +00001243- Issue #3008: the float type has a new instance method 'float.hex'
1244 and a new class method 'float.fromhex' to convert floating-point
1245 numbers to and from hexadecimal strings, respectively.
1246
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001247- Issue #2235: __hash__ is once again inherited by default. To allow
1248 collections.Hashable to remain meaningful in the presence of the
1249 default hash implementation (object.__hash__), it is now possible
1250 to explicit block inheritance of hash by setting __hash__=None at
1251 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1252 level.
1253
Nick Coghlanb028f502008-07-13 14:52:36 +00001254- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1255 the parent module cannot be found while performing an absolute import.
1256 This means that an incorrectly defined __package__ attribute will
1257 now only prevent relative imports in that module rather than causing
1258 all imports from that module to fail.
1259
Nick Coghlan14ff9942008-07-08 14:21:42 +00001260- Issue #2517: Allow unicode messages in Exceptions again by correctly
1261 bypassing the instance dictionary when looking up __unicode__ on
1262 new-style classes.
1263
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001264- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

1271
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001272- Issue #3004: Minor change to slice.indices(): the start and stop
1273 arguments are now treated identically, making the behaviour easier

1275 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1276 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1277 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00001731 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001732
1733 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00001793- Issue #1631171: Re-implement the 'warnings' module in C (the
1794 original Python code has been kept as backup). This will allow for
1795 using the 'warning's machinery in such places as the parser where
1796 use of pure Python code is not possible. Both the ``showarning()``
1797 and ``formatwarning()`` gain an optional 'line' argument which is
1798 not called by default for backwards-compatibility reasons. Setting
1799 ``warnings.showwarning()`` to an implementation that lacks support
1800 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001863- Issue #2550: The approach used by client/server code for obtaining
1864 ports to listen on in network-oriented tests has been refined in an
1865 effort to facilitate running multiple instances of the entire
1866 regression test suite in parallel without issue.
1867 test_support.bind_port() has been fixed such that it will always
1868 return a unique port -- which wasn't always the case with the
1869 previous implementation, especially if socket options had been set
1870 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1871 new implementation of bind_port() will actually raise an exception
1872 if it is passed an AF_INET/SOCK_STREAM socket with either the
1873 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1874 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1875 the socket it's been passed. This currently only applies to
1876 Windows. This option prevents any other sockets from binding to the
1877 host/port we've bound to, thus removing the possibility of the
1878 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1879 when a second SOCK_STREAM socket binds and accepts to a host/port
1880 that's already been bound by another socket. The optional preferred
1881 port parameter to bind_port() has been removed. Under no
1882 circumstances should tests be hard coding ports!
1883
1884 test_support.find_unused_port() has also been introduced, which will
1885 pass a temporary socket object to bind_port() in order to obtain an
1886 unused port. The temporary socket object is then closed and
1887 deleted, and the port is returned. This method should only be used
1888 for obtaining an unused port in order to pass to an external program
1889 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1890 a parameter to a server-oriented class that doesn't give you direct
1891 access to the underlying socket used.
1892
1893 Finally, test_support.HOST has been introduced, which should be used
1894 for the host argument of any relevant socket calls (i.e. bind and
1895 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001896
1897 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001898 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001899 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1900 test_asynchat and test_socket_ssl.
1901
Georg Brandl3ee81df2008-05-17 18:14:43 +00001902 It is now possible for multiple instances of the regression test
1903 suite to run in parallel without issue.

Facundo Batistac54aec12008-03-08 16:50:27 +00002086- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
Georg Brandl3ee81df2008-05-17 18:14:43 +00002087 optional: it defaults to the traceback of the exception that is
2088 currently being handled (is mandatory to be in the middle of an
2089 exception, otherwise it raises ValueError).

Thomas Hellerf3c05592008-03-05 15:34:29 +00002104- Issue #1872: The struct module typecode for _Bool has been changed
2105 from 't' to '?'.
2106
Thomas Heller78b8f442008-03-05 14:53:39 +00002107- The bundled libffi copy is now in sync with the recently released
2108 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002109 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2110 files are used. On all linux systems the --with-system-ffi
2111 configure option defaults to "yes".

2169Core and builtins
2170-----------------
2171
Fred Drakea8ee94b2008-03-01 02:45:07 +00002172- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002173 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002174
Georg Brandlad61bc82008-02-23 15:11:18 +00002175- Issue #2067: file.__exit__() now calls subclasses' close() method.
2176
2177- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002178
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002179- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002180 issue 215555 for a discussion.
2181
Eric Smitha73fbe72008-02-23 03:09:44 +00002182- Added the future_builtins module, which contains hex() and oct().
2183 These are the PEP 3127 version of these functions, designed to be
2184 compatible with the hex() and oct() builtins from Python 3.0. They
2185 differ slightly in their output formats from the existing, unchanged
2186 Python 2.6 builtins. The expected usage of the future_builtins
2187 module is:
2188 from future_builtins import hex, oct
2189
Eric Smith7ef40bf2008-02-20 23:34:22 +00002190- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2191 exponents for exponents with absolute value < 100. Follows C99
2192 standard. This is a change on Windows, which would use 3 digits.
2193 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2194 so that any alterations it does to the resulting string will be
2195 available in stringlib/formatter.h (for float.__format__).
2196
Eric Smith5a3c1352008-02-19 13:21:56 +00002197- Implemented PEP 3101, Advanced String Formatting. This adds a new
2198 builtin format(); a format() method for str and unicode; a
2199 __format__() method to object, str, unicode, int, long, float, and
2200 datetime; the class string.Formatter; and the C API
2201 PyObject_Format().
2202
Georg Brandl3ee81df2008-05-17 18:14:43 +00002203- Fixed several potential crashes, all caused by specially crafted
2204 __del__ methods exploiting objects in temporarily inconsistent
2205 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002206
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002207- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002208 prevent a possible crash: an Abstract Base Class would try to access
2209 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002210
Georg Brandl3ee81df2008-05-17 18:14:43 +00002211- Fixed repr() and str() of complex numbers with infinity or nan as
2212 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002213
Georg Brandl3ee81df2008-05-17 18:14:43 +00002214- Clear all free lists during a gc.collect() of the highest generation
2215 in order to allow pymalloc to free more arenas. Python may give back
2216 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002217
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- Issue #2045: Fix an infinite recursion triggered when printing a
2219 subclass of collections.defaultdict, if its default_factory is set
2220 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002221
Christian Heimesf75dbef2008-02-08 00:11:31 +00002222- Fixed a minor memory leak in dictobject.c. The content of the free
2223 list was not freed on interpreter shutdown.
2224
Georg Brandl3ee81df2008-05-17 18:14:43 +00002225- Limit free list of method and builtin function objects to 256
2226 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002227
Georg Brandl3ee81df2008-05-17 18:14:43 +00002228- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2229 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002230 to compact the internal free lists of pre-allocted ints and floats.
2231
Georg Brandl3ee81df2008-05-17 18:14:43 +00002232- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2233 calls. Python expected the return type int but the fork familie
2234 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002235
Georg Brandl3ee81df2008-05-17 18:14:43 +00002236- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2237 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002238
Georg Brandl3ee81df2008-05-17 18:14:43 +00002239- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2240 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002241
Georg Brandl3ee81df2008-05-17 18:14:43 +00002242- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2243 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002244
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2246 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002247
Georg Brandl3ee81df2008-05-17 18:14:43 +00002248- Patch #1473257: generator objects gain a gi_code attribute. This is
2249 the same object as the func_code attribute of the function that
2250 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002251
Georg Brandl3ee81df2008-05-17 18:14:43 +00002252- Issue #1920: "while 0" statements were completely removed by the
2253 compiler, even in the presence of an "else" clause, which is
2254 supposed to be run when the condition is false. Now the compiler
2255 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002256
Guido van Rossumeead05f2008-01-24 18:21:02 +00002257- A few crashers fixed: weakref_in_del.py (issue #1377858);
2258 loosing_dict_ref.py (issue #1303614, test67.py);
2259 borrowed_ref_[34].py (not in tracker).
2260
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002261- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002262 suppressed while an extension is loaded by calling SetErrorMode in
2263 dynload_win.c. The error is still reported properly.
2264
Georg Brandl3ee81df2008-05-17 18:14:43 +00002265- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002266 several extension methods and modules do not work without unicode
2267 support.
2268
Georg Brandl26543b12008-01-21 18:36:51 +00002269- Issue #1882: when compiling code from a string, encoding cookies in the
2270 second line of code were not always recognized correctly.
2271
Georg Brandl14404b62008-01-19 19:27:05 +00002272- Issue #1679: "0x" was taken as a valid integer literal.
2273
Georg Brandl6caad7d2008-01-26 14:19:22 +00002274- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002275 added.
2276
Christian Heimesc94e2b52008-01-14 04:13:37 +00002277- sys.float_info / PyFloat_GetInfo: The floating point information
2278 object was converted from a dict to a specialized structseq object.
2279
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280- Patch #1816: Added sys.flags structseq. It exposes the status of
2281 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002282
Georg Brandl3ee81df2008-05-17 18:14:43 +00002283- Objects/structseq.c: Implemented new structseq representation. The
2284 patch makes structseqs (e.g. the return value of os.stat) more
2285 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002286
Georg Brandl3ee81df2008-05-17 18:14:43 +00002287- Patch #1700288: added a type attribute cache that caches method

2296 envvar and sys.dont_write_bytecode attribute. All these can be set
2297 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002298
Georg Brandl3ee81df2008-05-17 18:14:43 +00002299- Improve some exception messages when Windows fails to load an
2300 extension module. Now we get for example '%1 is not a valid Win32
2301 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002302

Christian Heimes0a8143f2007-12-18 23:22:54 +00002308- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002309 and INF. float("nan"), float("inf") and float("-inf") now work on
2310 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002311
Georg Brandl3ee81df2008-05-17 18:14:43 +00002312- Compiler now generates simpler and faster code for dictionary
2313 literals. The oparg for BUILD_MAP now indicates an estimated
2314 dictionary size. There is a new opcode, STORE_MAP, for adding
2315 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002344- Patch #1739468: Directories and zipfiles containing a __main__.py
2345 file can now be directly executed by passing their name to the
2346 interpreter. The directory/zipfile is automatically inserted as the
2347 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002349- Issue #1265: Fix a problem with sys.settrace, if the tracing
2350 function uses a generator expression when at the same time the
2351 executed code is closing a paused generator.

2358
Georg Brandl3ee81df2008-05-17 18:14:43 +00002359- The enumerate() builtin function is no longer bounded to sequences
2360 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2361 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002362
Georg Brandl3ee81df2008-05-17 18:14:43 +00002363- Issue #1686386: Tuple's tp_repr did not take into account the
2364 possibility of having a self-referential tuple, which is possible
2365 from C code. Nor did object's tp_str consider that a type's tp_str
2366 could do something that could lead to an inifinite recursion.
2367 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2368 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002369
Georg Brandl3ee81df2008-05-17 18:14:43 +00002370- Issue #1164: It was possible to trigger deadlock when using the
2371 'print' statement to write to a file since the GIL was not released
2372 as needed. Now PyObject_Print() does the right thing along with
2373 various tp_print implementations of the built-in types and those in
2374 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002375
Georg Brandl3ee81df2008-05-17 18:14:43 +00002376- Issue #1147: Exceptions were directly allowing string exceptions in

2378 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00002383- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002384 PyObject_Call() never calling back out to Python code to trigger
2385 recursion depth updates/checks. Required the creation of a static
2386 RuntimeError instance in case normalizing an exception put the
2387 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00002403- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002404 __*__ attributes. (Some already existed, e.g., __doc__ and
2405 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002406
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002407- Add -3 option to the interpreter to warn about features that are

2411 calls.
2412
Collin Winter62903052007-05-18 23:11:24 +00002413- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002414 "except E as target:". This is to provide forwards compatibility
2415 with Python 3.0.

2421
Vinay Sajip8549ce32007-05-06 17:53:37 +00002422- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002423 setting a plain string, ie don't expand to single letter identifiers.
2424
Raymond Hettinger13936692007-04-11 18:40:58 +00002425- Request #1191699: Slices can now be pickled.
2426
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002427- Request #1193128: str.translate() now allows a None argument for

2429 remaining characters.
2430
Georg Brandl5cb76c12007-03-21 09:00:39 +00002431- Patch #1682205: a TypeError while unpacking an iterable is no longer

2435
Guido van Rossum143b5642007-03-23 04:58:42 +00002436- Bug #1683368: The object.__init__() and object.__new__() methods are
2437 now stricter in rejecting excess arguments. The only time when
2438 either allows excess arguments is when it is not overridden and the
2439 other one is. For backwards compatibility, when both are
2440 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002441 warning later). Also, type.__init__() insists on the same signature
2442 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002443
Georg Brandl3ee81df2008-05-17 18:14:43 +00002444- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2445 object to complex using its __complex__() method before falling back
2446 to the __float__() method. Therefore, the functions in the cmath
2447 module now can operate on objects that define a __complex__()
2448 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002449
Georg Brandl3ee81df2008-05-17 18:14:43 +00002450- Patch #1623563: allow __class__ assignment for classes with
2451 __slots__. The old and the new class are still required to have the
2452 same slot names.

2459 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00002466- Bug #1678647: write a newline after printing an exception in any
2467 case, even when converting the value to a string failed.
2468
Georg Brandl871f1bc2007-03-12 13:17:36 +00002469- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002470 its argument, if it exists. If not, it will work like before. This
2471 allows customizing the output of dir() in the presence of a
2472 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002480- Patch #1491866: change the complex() constructor to allow
2481 parthensized forms. This means complex(repr(x)) now works instead of
2482 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002483
Georg Brandlaa2321b2007-03-07 00:40:28 +00002484- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002485 makes the filenames the warning module prints much more sensible
2486 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002499- Patch #1674228: when assigning a slice (old-style), check for the
2500 sq_ass_slice instead of the sq_slice slot.
2501
Georg Brandl3ee81df2008-05-17 18:14:43 +00002502- When printing an unraisable error, don't print exceptions. before
2503 the name. This duplicates the behavior whening normally printing
2504 exceptions.

2561
Armin Rigo7ccbca92006-10-04 12:17:45 +00002562- A number of places, including integer negation and absolute value,

3132 -- the failure just occurred later, with a more cumbersome
3133 exception.

3347
Georg Brandl3ee81df2008-05-17 18:14:43 +00003348- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3415 with RFC 3207 and forgets any knowledge obtained from the server not
3416 obtained from the TLS negotiation itself. Patch contributed by Bill
3417 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003418
Georg Brandl3ee81df2008-05-17 18:14:43 +00003419- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003420 that the SMTP.starttls() caller no longer needs to call ehlo()
3421 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003422 does not claim to support starttls. Adds the
3423 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00003478- itertools.chain() now has an alternate constructor,

3504 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3505 silently miscode subclasses of those types. Now, it raises a
3506 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003507

Georg Brandl3ee81df2008-05-17 18:14:43 +00003522 time so that opening a database previously created with the DB_DUP
3523 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3524 opens. Specifically: dictionary assignment to a DB object will
3525 replace all values for a given key when the database allows
3526 duplicate values. DB users should use DB.put(k, v) when they want
3527 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003528

3534 characters with ASCII value less than 32. Also, it correctly quotes
3535 dots only if they occur on a single line, as opposed to the previous
3536 behavior of quoting dots if they are the second character of any
3537 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003538

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00003806- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00003807 periodic threadstate and signal checking in tight loops. By
3808 default, this option is turned-off. It should only be enabled in
3809 debugged, performance critical applications.

3861
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862- Unified naming convention for free lists and their limits. All free
3863 lists in Object/ are named ``free_list``, the counter ``numfree``

Christian Heimes5b970ad2008-02-06 13:33:44 +00003866
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3868 to ``PyTuple_SetItem``, it can be used to populate a brand new

3881
Georg Brandl3ee81df2008-05-17 18:14:43 +00003882- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3883 of w# format code incorrectly truncated the length to an int, even
3884 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3885 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003886
Georg Brandl3ee81df2008-05-17 18:14:43 +00003887- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

Georg Brandl3ee81df2008-05-17 18:14:43 +00003911- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3912 absolute imports. In earlier versions they might have used relative
3913 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003914
Georg Brandl3ee81df2008-05-17 18:14:43 +00003915- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3916 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003917
Georg Brandl3ee81df2008-05-17 18:14:43 +00003918- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003943- Removed the macfs module. It had been deprecated since Python 2.5.
3944 This lead to the deprecation of macostools.touched() as it relied
3945 solely on macfs and was a no-op under OS X.
