676What's New in Python 2.6.1
677==========================
678
679*Release date: 04-Dec-2008*
680
681Core and Builtins
682-----------------
683
684- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
685 interpreter to abort ("Fatal Python error: Could not reset the stack!")
686 instead of throwing a MemoryError.
687
688- Issue #4367: Python would segfault during compiling when the unicodedata
689 module couldn't be imported and \N escapes were present.
690
691- Issue #4348: Some bytearray methods returned that didn't cause any change to
692 the bytearray, returned the same bytearray instead of a copy.
693
694- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
695
696- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
697
698- Issue #4048: The parser module now correctly validates relative imports.
699
700- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
701 exec statement.
702
703- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
704 method does not return iterators for the 4th and 5th items.
705
706- Issue #4209: Enabling unicode_literals and the print_function in the same
707 __future__ import didn't work.
708
709- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
710 returned a path longer than MAX_PATH. (But It's doubtful this code path is
711 really executed because I cannot move to such directory on win2k)
712
713- Issue #4069: When set.remove(element) is used with a set element, the element
714 is temporarily replaced with an equivalent frozenset. But the eventual
715 KeyError would always report the empty frozenset([]) as the missing key. Now
716 it correctly refers to the initial element.
717
718- Fixed C99 style comments in several files. Python is now C89 compatible
719 again.

867
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000868- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
869 PyString_FromFormat or PyErr_Format to display size_t values. The macro
870 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
871 ``printf`` function, whereas PyString_FromFormat has an independent
872 implementation and uses "%zd" on all platforms for size_t values.
873 This makes a difference on win64, where ``printf`` needs "%Id" to display
874 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000894 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
895 mechanism. In the process, fix a bug where isinstance() and issubclass(),

991-----------------
992
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000993- Issue #2975: When compiling several extension modules with Visual Studio 2008
994 from the same python interpreter, some environment variables would grow
995 without limit.
996
Benjamin Peterson37346b22008-08-23 20:27:43 +0000997- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1003 remaining ones have "pysqlite_" prefix.
1004
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001005- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1013 wrapper for warnings.catch_warnings() that makes it easier to check
1014 that expected warning messages are being reported.
1015

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001034What's New in Python 2.6 beta 3?
1035================================
1036
Barry Warsaw07a4a382008-08-21 01:15:08 +00001037*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001038
1039Core and Builtins
1040-----------------
1041
Guido van Rossumf8402962008-08-20 15:01:50 +00001042- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1043 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1044 extensions do not automatically benefit from the class attribute
1045 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1046 to their tp_flags field if they care. This is a backwards
1047 compatibility feature; in 3.0, all types will use the cache by
1048 default.
1049
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001050- Keyword arguments can now follow starred arguments. (``f(a, *args,
1051 keyword=23)`` is now valid syntax.)
1052
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001053- ctypes function pointers that are COM methods have a boolean True
1054 value again.
1055
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001056- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1057 by denying s# to parse objects that have a releasebuffer procedure,
1058 and introducing s*.
1059
Georg Brandl1e13ea92008-08-11 09:07:59 +00001060- Issue #3537: Fix an assertion failure when an empty but presized dict
1061 object was stored in the freelist.
1062
Mark Dickinsonb6467572008-08-04 21:30:09 +00001063- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1064 ValueError consistently across platforms.
1065
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001066- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1067 (64bit Unix, for example), unichr() would truncate its argument and return
1068 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1069
Neal Norwitze7d8be82008-07-31 17:17:14 +00001070- Apply security patches from Apple.
1071
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001072- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1073 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1074
Antoine Pitrou92f82162008-07-25 22:22:08 +00001075- Issue #1819: function calls with several named parameters are now on
1076 average 35% faster (as measured by pybench).
1077
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001078- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1079 the python debugger steps into a class statement: the free variables (local
1080 variables defined in an outer scope) would be deleted from the outer scope.
1081
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001082- Issue #2620: Overflow checking when allocating or reallocating memory
1083 was not always being done properly in some python types and extension
1084 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1085 all been updated to perform better checks and places in the code that
1086 would previously leak memory on the error path when such an allocation
1087 failed have been fixed.
1088
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001089Library
1090-------
1091
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001092- Issue #3612: Added some missing basic types in ctypes.wintypes.
1093
Benjamin Petersone977ad42008-08-20 01:42:01 +00001094- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1095 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1096
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001097- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1098 version reported by these tools does not necessarily follow the python
1099 version numbering scheme, so the module is less strict when parsing it.
1100
Nick Coghlanf70385a2008-08-18 12:42:46 +00001101- Issue #2235: Added Py3k warnings for types which will become unhashable
1102 under the stricter __hash__ inheritance rules in 3.0. Several types
1103 which did not meet the rules for hash invariants and were already
1104 unhashable in 3.0 have now been explicitly flagged as unhashable in
1105 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1106 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1107
Brett Cannon88f801d2008-08-18 00:46:22 +00001108- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1109 imported into the module but exposed as part of the module's API.
1110
Brett Cannon7b96f072008-08-18 00:41:11 +00001111- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1112
Brett Cannon46225e72008-08-18 00:36:52 +00001113- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001115- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1116
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001117- Issue #3575: Incremental decoder's decode function now takes bytearray
1118 by using 's*' instead of 't#'.
1119
Jesus Cea585ad8a2009-07-02 15:37:21 +00001120- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001121 fails unicode conversion on 2nd parameter. (windows only)
1122
Facundo Batista94f243a2008-08-17 03:38:39 +00001123- Issue 2464. urllib2 now supports a malformation in the URL received
1124 in a redirect.
1125
Brett Cannonabe423e2008-08-16 21:47:07 +00001126- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001127 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001128
Facundo Batistaeb90b782008-08-16 14:44:07 +00001129- Issue #2776: fixed small issue when handling an URL with double slash
1130 after a 302 response in the case of not going through a proxy.
1131
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001132- Issue #2676: in the email package, content-type parsing was hanging on
1133 pathological input because of quadratic or exponential behaviour of a
1134 regular expression.
1135
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001136- Issue #3476: binary buffered reading through the new "io" library is now
1137 thread-safe.
1138
Brett Cannonbf3157b2008-08-14 05:00:03 +00001139- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1140 since mimetools itself is deprecated. Because modules are cached, all
1141 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1142
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001143- Issue #3134: shutil referenced undefined WindowsError symbol.
1144
Robert Schuppenies14646332008-08-10 11:01:53 +00001145- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1146 menu entries were not deleted.
1147
Brett Cannon83e81842008-08-09 23:30:55 +00001148- Copied the implementation of reduce() to _functools.reduce() to have a
1149 version that did not raise a DeprecationWarning under -3.
1150
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001151- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1152 a MemoryError rather than silently stop the iteration.
1153
Guido van Rossum59ce9012008-08-09 14:55:34 +00001154- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1155 to _sre.compile() will now be rejected. This should not affect anybody
1156 since the re.compile() function never generates invalid re-bytecode.
1157
Skip Montanaroa032bf42008-08-08 22:52:51 +00001158- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1159 upon first access it can be automatically initialized from the csv file if
1160 it wasn't initialized during instantiation.
1161
Brett Cannon3aa2a492008-08-06 22:28:09 +00001162- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1163 the reload() built-in has been removed.
1164
Brett Cannon7e30b672008-08-04 21:52:25 +00001165- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001166 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1169 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1170 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1171 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001173- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1174 raised an AttributeError.
1175
Benjamin Peterson01a24322008-07-28 23:35:27 +00001176- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001177 asking for a specific length. This problem only affected files opened
1178 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001179
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001180- Issue #3449: Update decimal module to use most recent specification
1181 (v. 1.68) and tests (v. 2.58) from IBM.

1191
1192- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1193 invalid arguments.
1194

1202
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001203- Issue #3394: zipfile.writestr sets external attributes when passed a
1204 file name rather than a ZipInfo instance, so files are extracted with
1205 mode 0600 rather than 000 under Unix.
1206
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001207- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1208 argument in python 2.5, this broke code that subclassed Popen to include its
1209 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001219- Issue #2235: the C API function PyObject_HashNotImplemented and its
1220 interaction with the tp_hash slot (added in 2.6b2) are now documented
1221
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001222- Issue #643841: The language reference now provides more detailed
1223 coverage of the lookup process for special methods. The disclaimers
1224 regarding lack of coverage of new-style classes have also been
1225 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001228What's New in Python 2.6 beta 2?
1229================================
1230
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001231*Release date: 17-Jul-2008*
1232
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001233Core and Builtins
1234-----------------
1235
Georg Brandl3e483f62008-07-16 22:57:41 +00001236- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1237 its methods now allow for items objects that can be converted to
1238 an integer using operator.index().
1239
Mark Dickinson64b7e502008-07-16 09:40:03 +00001240- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1241 produced a ValueError instead of giving the correct float.
1242
Eric Smitha5fa5a22008-07-16 00:11:49 +00001243- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1244 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1245
Mark Dickinson7103aa42008-07-15 19:08:33 +00001246- Issue #3008: the float type has a new instance method 'float.hex'
1247 and a new class method 'float.fromhex' to convert floating-point
1248 numbers to and from hexadecimal strings, respectively.
1249
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001250- Issue #2235: __hash__ is once again inherited by default. To allow
1251 collections.Hashable to remain meaningful in the presence of the
1252 default hash implementation (object.__hash__), it is now possible
1253 to explicit block inheritance of hash by setting __hash__=None at
1254 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1255 level.
1256
Nick Coghlanb028f502008-07-13 14:52:36 +00001257- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1258 the parent module cannot be found while performing an absolute import.
1259 This means that an incorrectly defined __package__ attribute will
1260 now only prevent relative imports in that module rather than causing
1261 all imports from that module to fail.
1262
Nick Coghlan14ff9942008-07-08 14:21:42 +00001263- Issue #2517: Allow unicode messages in Exceptions again by correctly
1264 bypassing the instance dictionary when looking up __unicode__ on
1265 new-style classes.
1266
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001267- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

1276 arguments are now treated identically, making the behaviour easier

1279 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1280 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00001734 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001735
1736 This is controlled by the configure argument ``--with-universal-archs``:

1740 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1741
1742 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

Georg Brandl3ee81df2008-05-17 18:14:43 +00001796- Issue #1631171: Re-implement the 'warnings' module in C (the
1797 original Python code has been kept as backup). This will allow for
1798 using the 'warning's machinery in such places as the parser where
1799 use of pure Python code is not possible. Both the ``showarning()``
1800 and ``formatwarning()`` gain an optional 'line' argument which is
1801 not called by default for backwards-compatibility reasons. Setting
1802 ``warnings.showwarning()`` to an implementation that lacks support
1803 for the ``line`` argument will raise a DeprecationWarning.

1848
Gregory P. Smithaa63d0d2008-04-06 23:11:17 +00001849- Issue #815646: Individual file objects may now be used from multiple
1850 threads at once without fear of crashing the Python interpreter. If
1851 file.close() is called while an object is in use by another thread
1852 an IOError exception will be raised and the file will not be closed.
1853
Thomas Hellerf7906482008-04-04 19:43:25 +00001854- The bundled libffi copy is now in sync with the recently released

1857
Georg Brandl3ee81df2008-05-17 18:14:43 +00001858- Issue #2385: distutils.core.run_script() makes __file__ available,
1859 so the controlled environment will more closely mirror the typical
1860 script environment. This supports setup.py scripts that refer to
1861 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001866- Issue #2550: The approach used by client/server code for obtaining
1867 ports to listen on in network-oriented tests has been refined in an
1868 effort to facilitate running multiple instances of the entire
1869 regression test suite in parallel without issue.
1870 test_support.bind_port() has been fixed such that it will always
1871 return a unique port -- which wasn't always the case with the
1872 previous implementation, especially if socket options had been set
1873 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1874 new implementation of bind_port() will actually raise an exception
1875 if it is passed an AF_INET/SOCK_STREAM socket with either the
1876 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1877 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1878 the socket it's been passed. This currently only applies to
1879 Windows. This option prevents any other sockets from binding to the
1880 host/port we've bound to, thus removing the possibility of the
1881 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1882 when a second SOCK_STREAM socket binds and accepts to a host/port
1883 that's already been bound by another socket. The optional preferred
1884 port parameter to bind_port() has been removed. Under no
1885 circumstances should tests be hard coding ports!
1886
1887 test_support.find_unused_port() has also been introduced, which will
1888 pass a temporary socket object to bind_port() in order to obtain an
1889 unused port. The temporary socket object is then closed and
1890 deleted, and the port is returned. This method should only be used
1891 for obtaining an unused port in order to pass to an external program
1892 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1893 a parameter to a server-oriented class that doesn't give you direct
1894 access to the underlying socket used.
1895
1896 Finally, test_support.HOST has been introduced, which should be used
1897 for the host argument of any relevant socket calls (i.e. bind and
1898 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001899
1900 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001901 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001902 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1903 test_asynchat and test_socket_ssl.
1904
Georg Brandl3ee81df2008-05-17 18:14:43 +00001905 It is now possible for multiple instances of the regression test
1906 suite to run in parallel without issue.

Facundo Batistac54aec12008-03-08 16:50:27 +00002089- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
Georg Brandl3ee81df2008-05-17 18:14:43 +00002090 optional: it defaults to the traceback of the exception that is
2091 currently being handled (is mandatory to be in the middle of an
2092 exception, otherwise it raises ValueError).

Thomas Hellerf3c05592008-03-05 15:34:29 +00002107- Issue #1872: The struct module typecode for _Bool has been changed
2108 from 't' to '?'.
2109
Thomas Heller78b8f442008-03-05 14:53:39 +00002110- The bundled libffi copy is now in sync with the recently released
2111 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002112 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2113 files are used. On all linux systems the --with-system-ffi
2114 configure option defaults to "yes".

2172Core and builtins
2173-----------------
2174
Fred Drakea8ee94b2008-03-01 02:45:07 +00002175- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002176 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002177
Georg Brandlad61bc82008-02-23 15:11:18 +00002178- Issue #2067: file.__exit__() now calls subclasses' close() method.
2179
2180- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002181
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002182- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002183 issue 215555 for a discussion.
2184
Eric Smitha73fbe72008-02-23 03:09:44 +00002185- Added the future_builtins module, which contains hex() and oct().
2186 These are the PEP 3127 version of these functions, designed to be
2187 compatible with the hex() and oct() builtins from Python 3.0. They
2188 differ slightly in their output formats from the existing, unchanged
2189 Python 2.6 builtins. The expected usage of the future_builtins
2190 module is:
2191 from future_builtins import hex, oct
2192
Eric Smith7ef40bf2008-02-20 23:34:22 +00002193- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2194 exponents for exponents with absolute value < 100. Follows C99
2195 standard. This is a change on Windows, which would use 3 digits.
2196 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2197 so that any alterations it does to the resulting string will be
2198 available in stringlib/formatter.h (for float.__format__).
2199
Eric Smith5a3c1352008-02-19 13:21:56 +00002200- Implemented PEP 3101, Advanced String Formatting. This adds a new
2201 builtin format(); a format() method for str and unicode; a
2202 __format__() method to object, str, unicode, int, long, float, and
2203 datetime; the class string.Formatter; and the C API
2204 PyObject_Format().
2205
Georg Brandl3ee81df2008-05-17 18:14:43 +00002206- Fixed several potential crashes, all caused by specially crafted
2207 __del__ methods exploiting objects in temporarily inconsistent
2208 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002209
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002210- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002211 prevent a possible crash: an Abstract Base Class would try to access
2212 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002213
Georg Brandl3ee81df2008-05-17 18:14:43 +00002214- Fixed repr() and str() of complex numbers with infinity or nan as
2215 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002216
Georg Brandl3ee81df2008-05-17 18:14:43 +00002217- Clear all free lists during a gc.collect() of the highest generation
2218 in order to allow pymalloc to free more arenas. Python may give back
2219 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002220
Georg Brandl3ee81df2008-05-17 18:14:43 +00002221- Issue #2045: Fix an infinite recursion triggered when printing a
2222 subclass of collections.defaultdict, if its default_factory is set
2223 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002224
Christian Heimesf75dbef2008-02-08 00:11:31 +00002225- Fixed a minor memory leak in dictobject.c. The content of the free
2226 list was not freed on interpreter shutdown.
2227
Georg Brandl3ee81df2008-05-17 18:14:43 +00002228- Limit free list of method and builtin function objects to 256
2229 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002230
Georg Brandl3ee81df2008-05-17 18:14:43 +00002231- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2232 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002233 to compact the internal free lists of pre-allocted ints and floats.
2234
Georg Brandl3ee81df2008-05-17 18:14:43 +00002235- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2236 calls. Python expected the return type int but the fork familie
2237 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002238
Georg Brandl3ee81df2008-05-17 18:14:43 +00002239- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2240 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002241
Georg Brandl3ee81df2008-05-17 18:14:43 +00002242- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2243 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002244
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2246 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002247
Georg Brandl3ee81df2008-05-17 18:14:43 +00002248- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2249 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002250
Georg Brandl3ee81df2008-05-17 18:14:43 +00002251- Patch #1473257: generator objects gain a gi_code attribute. This is
2252 the same object as the func_code attribute of the function that
2253 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002254
Georg Brandl3ee81df2008-05-17 18:14:43 +00002255- Issue #1920: "while 0" statements were completely removed by the
2256 compiler, even in the presence of an "else" clause, which is
2257 supposed to be run when the condition is false. Now the compiler
2258 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002259
Guido van Rossumeead05f2008-01-24 18:21:02 +00002260- A few crashers fixed: weakref_in_del.py (issue #1377858);
2261 loosing_dict_ref.py (issue #1303614, test67.py);
2262 borrowed_ref_[34].py (not in tracker).
2263
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002264- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002265 suppressed while an extension is loaded by calling SetErrorMode in
2266 dynload_win.c. The error is still reported properly.
2267
Georg Brandl3ee81df2008-05-17 18:14:43 +00002268- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002269 several extension methods and modules do not work without unicode
2270 support.
2271
Georg Brandl26543b12008-01-21 18:36:51 +00002272- Issue #1882: when compiling code from a string, encoding cookies in the
2273 second line of code were not always recognized correctly.
2274
Georg Brandl14404b62008-01-19 19:27:05 +00002275- Issue #1679: "0x" was taken as a valid integer literal.
2276
Georg Brandl6caad7d2008-01-26 14:19:22 +00002277- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002278 added.
2279
Christian Heimesc94e2b52008-01-14 04:13:37 +00002280- sys.float_info / PyFloat_GetInfo: The floating point information
2281 object was converted from a dict to a specialized structseq object.
2282
Georg Brandl3ee81df2008-05-17 18:14:43 +00002283- Patch #1816: Added sys.flags structseq. It exposes the status of
2284 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002285
Georg Brandl3ee81df2008-05-17 18:14:43 +00002286- Objects/structseq.c: Implemented new structseq representation. The
2287 patch makes structseqs (e.g. the return value of os.stat) more
2288 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002289
Georg Brandl3ee81df2008-05-17 18:14:43 +00002290- Patch #1700288: added a type attribute cache that caches method
2291 accesses, resulting in speedups in heavily object-oriented code.

2300 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002301
Georg Brandl3ee81df2008-05-17 18:14:43 +00002302- Improve some exception messages when Windows fails to load an
2303 extension module. Now we get for example '%1 is not a valid Win32
2304 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002305

2309 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002310
Christian Heimes0a8143f2007-12-18 23:22:54 +00002311- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002312 and INF. float("nan"), float("inf") and float("-inf") now work on
2313 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002314
Georg Brandl3ee81df2008-05-17 18:14:43 +00002315- Compiler now generates simpler and faster code for dictionary
2316 literals. The oparg for BUILD_MAP now indicates an estimated
2317 dictionary size. There is a new opcode, STORE_MAP, for adding
2318 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002347- Patch #1739468: Directories and zipfiles containing a __main__.py
2348 file can now be directly executed by passing their name to the
2349 interpreter. The directory/zipfile is automatically inserted as the
2350 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002352- Issue #1265: Fix a problem with sys.settrace, if the tracing
2353 function uses a generator expression when at the same time the
2354 executed code is closing a paused generator.

2361
Georg Brandl3ee81df2008-05-17 18:14:43 +00002362- The enumerate() builtin function is no longer bounded to sequences
2363 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2364 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002365
Georg Brandl3ee81df2008-05-17 18:14:43 +00002366- Issue #1686386: Tuple's tp_repr did not take into account the
2367 possibility of having a self-referential tuple, which is possible
2368 from C code. Nor did object's tp_str consider that a type's tp_str
2369 could do something that could lead to an inifinite recursion.
2370 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2371 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002372
Georg Brandl3ee81df2008-05-17 18:14:43 +00002373- Issue #1164: It was possible to trigger deadlock when using the
2374 'print' statement to write to a file since the GIL was not released
2375 as needed. Now PyObject_Print() does the right thing along with
2376 various tp_print implementations of the built-in types and those in
2377 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002378
Georg Brandl3ee81df2008-05-17 18:14:43 +00002379- Issue #1147: Exceptions were directly allowing string exceptions in

2381 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00002385
Brett Cannon1e534b52007-09-07 04:18:30 +00002386- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002387 PyObject_Call() never calling back out to Python code to trigger
2388 recursion depth updates/checks. Required the creation of a static
2389 RuntimeError instance in case normalizing an exception put the
2390 recursion check value past its limit. Fixes crashers
2391 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002406- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002407 __*__ attributes. (Some already existed, e.g., __doc__ and
2408 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002409
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002410- Add -3 option to the interpreter to warn about features that are
2411 deprecated and will be changed/removed in Python 3.0.
2412
Georg Brandl2134e752007-05-21 20:34:16 +00002413- Patch #1686487: you can now pass any mapping after '**' in function
2414 calls.
2415
Collin Winter62903052007-05-18 23:11:24 +00002416- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002417 "except E as target:". This is to provide forwards compatibility
2418 with Python 3.0.

2424
Vinay Sajip8549ce32007-05-06 17:53:37 +00002425- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002426 setting a plain string, ie don't expand to single letter identifiers.
2427
Raymond Hettinger13936692007-04-11 18:40:58 +00002428- Request #1191699: Slices can now be pickled.
2429
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002430- Request #1193128: str.translate() now allows a None argument for
2431 translations that only remove characters without re-mapping the
2432 remaining characters.
2433
Georg Brandl5cb76c12007-03-21 09:00:39 +00002434- Patch #1682205: a TypeError while unpacking an iterable is no longer

2436
Neal Norwitzaa754b72007-03-21 06:39:48 +00002437- Remove unused file Python/fmod.c.
2438
Guido van Rossum143b5642007-03-23 04:58:42 +00002439- Bug #1683368: The object.__init__() and object.__new__() methods are
2440 now stricter in rejecting excess arguments. The only time when
2441 either allows excess arguments is when it is not overridden and the
2442 other one is. For backwards compatibility, when both are
2443 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002444 warning later). Also, type.__init__() insists on the same signature
2445 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002446
Georg Brandl3ee81df2008-05-17 18:14:43 +00002447- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2448 object to complex using its __complex__() method before falling back
2449 to the __float__() method. Therefore, the functions in the cmath
2450 module now can operate on objects that define a __complex__()
2451 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002452
Georg Brandl3ee81df2008-05-17 18:14:43 +00002453- Patch #1623563: allow __class__ assignment for classes with
2454 __slots__. The old and the new class are still required to have the
2455 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002456

2461 ``object.__reduce_ex__()`` is called with an object that is faking
2462 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002463
Georg Brandl3ee81df2008-05-17 18:14:43 +00002464- Patch #1680015: Don't modify __slots__ tuple if it contains an

2468
Georg Brandl7b9c5552007-03-12 14:30:05 +00002469- Bug #1678647: write a newline after printing an exception in any
2470 case, even when converting the value to a string failed.
2471
Georg Brandl871f1bc2007-03-12 13:17:36 +00002472- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002473 its argument, if it exists. If not, it will work like before. This
2474 allows customizing the output of dir() in the presence of a
2475 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002483- Patch #1491866: change the complex() constructor to allow
2484 parthensized forms. This means complex(repr(x)) now works instead of
2485 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002486
Georg Brandlaa2321b2007-03-07 00:40:28 +00002487- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002488 makes the filenames the warning module prints much more sensible
2489 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002490

Georg Brandl098cd692007-03-06 12:17:50 +00002501
Georg Brandl0fca97a2007-03-05 22:28:08 +00002502- Patch #1674228: when assigning a slice (old-style), check for the
2503 sq_ass_slice instead of the sq_slice slot.
2504
Georg Brandl3ee81df2008-05-17 18:14:43 +00002505- When printing an unraisable error, don't print exceptions. before
2506 the name. This duplicates the behavior whening normally printing
2507 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002508

2564
Armin Rigo7ccbca92006-10-04 12:17:45 +00002565- A number of places, including integer negation and absolute value,

3132 TestCase and TestSuite subclasses (not instances) are no longer
3133 accepted in TestSuite.addTest(). This should cause no

3135 -- the failure just occurred later, with a more cumbersome
3136 exception.

3350
Georg Brandl3ee81df2008-05-17 18:14:43 +00003351- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003417- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3418 with RFC 3207 and forgets any knowledge obtained from the server not
3419 obtained from the TLS negotiation itself. Patch contributed by Bill
3420 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003421
Georg Brandl3ee81df2008-05-17 18:14:43 +00003422- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003423 that the SMTP.starttls() caller no longer needs to call ehlo()
3424 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003425 does not claim to support starttls. Adds the
3426 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00003481- itertools.chain() now has an alternate constructor,

3507 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3508 silently miscode subclasses of those types. Now, it raises a
3509 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003510

Georg Brandl3ee81df2008-05-17 18:14:43 +00003525 time so that opening a database previously created with the DB_DUP
3526 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3527 opens. Specifically: dictionary assignment to a DB object will
3528 replace all values for a given key when the database allows
3529 duplicate values. DB users should use DB.put(k, v) when they want
3530 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003531

3537 characters with ASCII value less than 32. Also, it correctly quotes
3538 dots only if they occur on a single line, as opposed to the previous
3539 behavior of quoting dots if they are the second character of any
3540 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003541

Georg Brandl3ee81df2008-05-17 18:14:43 +00003810 periodic threadstate and signal checking in tight loops. By
3811 default, this option is turned-off. It should only be enabled in
3812 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00003869
Georg Brandl3ee81df2008-05-17 18:14:43 +00003870- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3871 to ``PyTuple_SetItem``, it can be used to populate a brand new

3884
Georg Brandl3ee81df2008-05-17 18:14:43 +00003885- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3886 of w# format code incorrectly truncated the length to an int, even
3887 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3888 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003889
Georg Brandl3ee81df2008-05-17 18:14:43 +00003890- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3912 outside of pystate.c and should not be necessary.
3913
Georg Brandl3ee81df2008-05-17 18:14:43 +00003914- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3915 absolute imports. In earlier versions they might have used relative
3916 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003917
Georg Brandl3ee81df2008-05-17 18:14:43 +00003918- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3919 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003920
Georg Brandl3ee81df2008-05-17 18:14:43 +00003921- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

3931 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003932

Georg Brandl3ee81df2008-05-17 18:14:43 +00003946- Removed the macfs module. It had been deprecated since Python 2.5.
3947 This lead to the deprecation of macostools.touched() as it relied
3948 solely on macfs and was a no-op under OS X.
