Victor Stinner082a65a2010-07-28 01:55:43 +000032- Issue #6213: Implement getstate() and setstate() methods of utf-8-sig and
33 utf-16 incremental encoders.
34
Ezio Melotti86e5e172010-07-03 05:34:39 +000035- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
36 start byte and the continuation byte(s) are now considered invalid, instead
37 of the number of bytes specified by the start byte.
38 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
39 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
40 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
41 Previous versions returned a single u'\ufffd'.

Mark Dickinsonb671c292010-06-05 12:15:35 +000050 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
51 arises from the "Overriding __eq__ blocks inheritance ..." warning
52 when turned into an exception: in this case the exception simply
53 gets ignored.

Georg Brandl0ba1f012010-08-01 22:00:39 +000055- Issue #4108: In urllib.robotparser, if there are multiple 'User-agent: *'

71
Mark Dickinsone02c9d22010-05-07 13:23:18 +000072- Issue #1533: fix inconsistency in range function argument
73 processing: any non-float non-integer argument is now converted to
74 an integer (if possible) using its __int__ method. Previously, only
75 small arguments were treated this way; larger arguments (those whose
76 __int__ was outside the range of a C long) would produce a TypeError.
77

1240
Barry Warsaw90971e02009-04-07 01:54:02 +00001241- Issue #4034: Fix weird attribute error messages of the traceback object. (As

Benjamin Peterson53f098c2009-03-18 21:49:29 +00001243
Eric Smith1718b472009-02-20 14:07:55 +00001244- Issue #5247: Improve error message when unknown format codes are

1253
Georg Brandl21896072010-08-01 22:31:28 +00001254- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettinger24e28722009-02-02 22:44:06 +00001255 were suppressing all exceptions. These include list(), filter(), map(),

1260 the interpreter segfault instead of raising an error.
1261
Georg Brandl686d53e2009-01-14 00:08:09 +00001262- Issue #4915: Port sysmodule to Windows CE.

1265 an existing .py counterpart, override the co_filename attributes of all
1266 code objects if the original filename is obsolete (which can happen if the

1268 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1269
Georg Brandl734373c2009-01-03 21:55:17 +00001270- Issue #4075: Use OutputDebugStringW in Py_FatalError.

1280
Georg Brandl47fe9812009-01-01 15:46:10 +00001281- Issue #4764: With io.open, IOError.filename is set when trying to open a

1285 systems.

1293 fail.
1294
Jeffrey Yasskin69614982008-12-11 05:21:18 +00001295- Issue #4597: Fixed several opcodes that weren't always propagating
1296 exceptions.
1297
Benjamin Petersonc6e80eb2008-12-21 17:01:26 +00001298- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1304
Vinay Sajip6badbe92009-01-20 22:49:13 +00001305- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +00001306 method on file objects with closefd=False. The file descriptor is still
1307 kept open but the file object behaves like a closed file. The ``FileIO``
1308 object also got a new readonly attribute ``closefd``.
1309
Georg Brandlfa71a902008-12-05 09:08:28 +00001310- Issue #3689: The list reversed iterator now supports __length_hint__

1483 do an explicit seek to the end of file (so that e.g. tell() returns the

1485 traditional 2.x file object.

1681What's New in Python 2.6.1
1682==========================
1683
1684*Release date: 04-Dec-2008*
1685
1686Core and Builtins
1687-----------------
1688
1689- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1690 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1691 instead of throwing a MemoryError.
1692
1693- Issue #4367: Python would segfault during compiling when the unicodedata
1694 module couldn't be imported and \N escapes were present.
1695
1696- Issue #4348: Some bytearray methods returned that didn't cause any change to
1697 the bytearray, returned the same bytearray instead of a copy.
1698
1699- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1700
1701- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1702
1703- Issue #4048: The parser module now correctly validates relative imports.
1704
1705- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1710
1711- Issue #4209: Enabling unicode_literals and the print_function in the same
1712 __future__ import didn't work.
1713
1714- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1715 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1716 really executed because I cannot move to such directory on win2k)
1717
1718- Issue #4069: When set.remove(element) is used with a set element, the element
1719 is temporarily replaced with an equivalent frozenset. But the eventual
1720 KeyError would always report the empty frozenset([]) as the missing key. Now
1721 it correctly refers to the initial element.
1722
1723- Fixed C99 style comments in several files. Python is now C89 compatible
1724 again.

1870
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001871- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1872
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001873- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1874 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1875 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1876 ``printf`` function, whereas PyString_FromFormat has an independent
1877 implementation and uses "%zd" on all platforms for size_t values.
1878 This makes a difference on win64, where ``printf`` needs "%Id" to display
1879 64bit values.
1880
Benjamin Peterson97179b02008-09-09 20:55:01 +00001881- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1882 error.
1883
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001884- Issue #3777: long() applied to a float object now always return a long
1885 object; previously an int would be returned for small values. the __long__
1886 method is allowed to return either an int or a long, but the behaviour of
1887 float objects should not change to respect backward compatibility.
1888
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001889- Issue #3751: str.rpartition would perform a left-partition when called with
1890 a unicode argument.
1891
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001892- Issue #3683: Fix compilation when --without-threads is given.
1893
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001894- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001895 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001896 was correctly parsed but parsing of subsequent arguments failed.
1897
Vinay Sajip35e3b032008-09-01 14:33:59 +00001898- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001899 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1900 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1901 when given a tuple of classes as second argument, were looking up
1902 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1903 type object.
1904
Neal Norwitz18aa3882008-08-24 05:04:52 +00001905- Fix crashes on memory allocation failure found with failmalloc.
1906
1907- Fix memory leaks found with valgrind and update suppressions file.
1908
1909- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1910
1911- Fix problem using wrong name in decimal module reported by pychecker.
1912
Christian Heimes7d4c3172008-08-22 19:47:25 +00001913- Silenced another compiler warning about a used but not defined
1914 function 'stringlib_contains_obj'.
1915
Benjamin Peterson712ee922008-08-24 18:10:20 +00001916- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1917 ``__delslice__``.
1918
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001919- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1920 library targets in the Makefile.
1921
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001922- Issue #1204: The configure script now tests for additional libraries
1923 that may be required when linking against readline. This fixes issues
1924 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
1925
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00001926C-API

1933
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00001934- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
1935 stack usage in the case of deeply nested objects.
1936
Guido van Rossume3c4fd92008-09-10 14:27:00 +00001937- Issue #3629: Fix sre "bytecode" validator for an end case.
1938

1940
Nick Coghland2e09382008-09-11 12:11:06 +00001941- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1942 silent misbehaviour when a single instance is nested in multiple
1943 with statements, or when the methods are invoked in the wrong order.
1944

1946
Nick Coghland2e09382008-09-11 12:11:06 +00001947- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001948 return a list or None rather than a custom object.
1949
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001950- Issue #1638033: Cookie.Morsel gained the httponly attribute.
1951
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00001952- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon32476fc2008-09-05 18:33:51 +00001955
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +00001956- Issue #3762: platform.architecture() fails if python is lanched via
1957 its symbolic link.
1958
Vinay Sajip65d66e12008-09-04 07:31:21 +00001959- Issue #3772: Fixed regression problem in StreamHandler.emit().

Facundo Batistac585df92008-09-03 22:35:50 +00001962 to the urlparse one. Added a PendingDeprecationWarning in the old
1963 module, it will be deprecated in the future.

1971 path to the Python binary.
1972
Georg Brandl21896072010-08-01 22:31:28 +00001973- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00001974 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1975 for catch_warnings() also led to an improvement in the raising of a
1976 DeprecationWarning related to warnings.warn_explicit().
1977
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001978- The deprecation warnings for the old camelCase threading API were removed.
1979
Vinay Sajip35e3b032008-09-01 14:33:59 +00001980- logging: fixed lack of use of encoding attribute specified on a stream.
1981
Christian Heimesa27a62e2008-08-22 19:55:54 +00001982- Silenced a trivial compiler warning in the sqlite module.
1983
Christian Heimes1cc69632008-08-22 20:10:27 +00001984- Fixed two format strings in the _collections module.
1985

1987 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00001988
Gregory P. Smithd7122032008-09-02 05:36:11 +00001989- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
1990 non-integer floating point number.

Benjamin Peterson37346b22008-08-23 20:27:43 +00001995Extension Modules
1996-----------------
1997
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001998- Issue #2975: When compiling several extension modules with Visual Studio 2008
1999 from the same python interpreter, some environment variables would grow
2000 without limit.
2001
Benjamin Peterson37346b22008-08-23 20:27:43 +00002002- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2003 exploitation of poor argument checking.
2004
Gerhard Häringef2276b2008-09-12 13:54:06 +00002005- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
2006
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00002007- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
2008 remaining ones have "pysqlite_" prefix.
2009
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002010- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves
2011 concurrent access to the same SQLite database from multiple

2016
Nick Coghland2e09382008-09-11 12:11:06 +00002017- Issue #3781: Add test.test_support.check_warnings() as a convenience
2018 wrapper for warnings.catch_warnings() that makes it easier to check
2019 that expected warning messages are being reported.
2020
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002021- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002039What's New in Python 2.6 beta 3?
2040================================
2041
Barry Warsaw07a4a382008-08-21 01:15:08 +00002042*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002043
2044Core and Builtins
2045-----------------
2046
Guido van Rossumf8402962008-08-20 15:01:50 +00002047- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2048 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2049 extensions do not automatically benefit from the class attribute
2050 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2051 to their tp_flags field if they care. This is a backwards
2052 compatibility feature; in 3.0, all types will use the cache by
2053 default.
2054
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002055- Keyword arguments can now follow starred arguments. (``f(a, *args,
2056 keyword=23)`` is now valid syntax.)
2057
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002058- ctypes function pointers that are COM methods have a boolean True
2059 value again.
2060
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002061- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2062 by denying s# to parse objects that have a releasebuffer procedure,
2063 and introducing s*.
2064
Georg Brandl1e13ea92008-08-11 09:07:59 +00002065- Issue #3537: Fix an assertion failure when an empty but presized dict
2066 object was stored in the freelist.
2067
Mark Dickinsonb6467572008-08-04 21:30:09 +00002068- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2069 ValueError consistently across platforms.
2070
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002071- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2072 (64bit Unix, for example), unichr() would truncate its argument and return
2073 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2074
Neal Norwitze7d8be82008-07-31 17:17:14 +00002075- Apply security patches from Apple.
2076
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002077- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2078 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2079
Antoine Pitrou92f82162008-07-25 22:22:08 +00002080- Issue #1819: function calls with several named parameters are now on
2081 average 35% faster (as measured by pybench).
2082
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002083- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2084 the python debugger steps into a class statement: the free variables (local
2085 variables defined in an outer scope) would be deleted from the outer scope.
2086
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002087- Issue #2620: Overflow checking when allocating or reallocating memory
2088 was not always being done properly in some python types and extension
2089 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2090 all been updated to perform better checks and places in the code that
2091 would previously leak memory on the error path when such an allocation
2092 failed have been fixed.
2093
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002094Library
2095-------
2096
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002097- Issue #3612: Added some missing basic types in ctypes.wintypes.
2098
Benjamin Petersone977ad42008-08-20 01:42:01 +00002099- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2100 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2101
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002102- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2103 version reported by these tools does not necessarily follow the python
2104 version numbering scheme, so the module is less strict when parsing it.
2105
Nick Coghlanf70385a2008-08-18 12:42:46 +00002106- Issue #2235: Added Py3k warnings for types which will become unhashable
2107 under the stricter __hash__ inheritance rules in 3.0. Several types
2108 which did not meet the rules for hash invariants and were already
2109 unhashable in 3.0 have now been explicitly flagged as unhashable in
2110 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2111 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2112
Brett Cannon88f801d2008-08-18 00:46:22 +00002113- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2114 imported into the module but exposed as part of the module's API.
2115
Brett Cannon7b96f072008-08-18 00:41:11 +00002116- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2117
Brett Cannon46225e72008-08-18 00:36:52 +00002118- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002120- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2121
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002122- Issue #3575: Incremental decoder's decode function now takes bytearray
2123 by using 's*' instead of 't#'.
2124
Jesus Cea585ad8a2009-07-02 15:37:21 +00002125- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002126 fails unicode conversion on 2nd parameter. (windows only)
2127
Georg Brandl21896072010-08-01 22:31:28 +00002128- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00002129 in a redirect.
2130
Brett Cannonabe423e2008-08-16 21:47:07 +00002131- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002132 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002133
Facundo Batistaeb90b782008-08-16 14:44:07 +00002134- Issue #2776: fixed small issue when handling an URL with double slash
2135 after a 302 response in the case of not going through a proxy.
2136
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002137- Issue #2676: in the email package, content-type parsing was hanging on
2138 pathological input because of quadratic or exponential behaviour of a
2139 regular expression.
2140
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002141- Issue #3476: binary buffered reading through the new "io" library is now
2142 thread-safe.
2143
Brett Cannonbf3157b2008-08-14 05:00:03 +00002144- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2145 since mimetools itself is deprecated. Because modules are cached, all
2146 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2147
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002148- Issue #3134: shutil referenced undefined WindowsError symbol.
2149
Robert Schuppenies14646332008-08-10 11:01:53 +00002150- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2151 menu entries were not deleted.
2152
Brett Cannon83e81842008-08-09 23:30:55 +00002153- Copied the implementation of reduce() to _functools.reduce() to have a
2154 version that did not raise a DeprecationWarning under -3.

Antoine Pitroude781a42008-08-09 12:43:23 +00002182 asking for a specific length. This problem only affected files opened

2226
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002227- Issue #643841: The language reference now provides more detailed

2239-----------------
2240
Georg Brandl3e483f62008-07-16 22:57:41 +00002241- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2242 its methods now allow for items objects that can be converted to
2243 an integer using operator.index().
2244
Mark Dickinson64b7e502008-07-16 09:40:03 +00002245- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2246 produced a ValueError instead of giving the correct float.
2247
Eric Smitha5fa5a22008-07-16 00:11:49 +00002248- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2249 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2250
Mark Dickinson7103aa42008-07-15 19:08:33 +00002251- Issue #3008: the float type has a new instance method 'float.hex'
2252 and a new class method 'float.fromhex' to convert floating-point
2253 numbers to and from hexadecimal strings, respectively.
2254
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002255- Issue #2235: __hash__ is once again inherited by default. To allow
2256 collections.Hashable to remain meaningful in the presence of the
2257 default hash implementation (object.__hash__), it is now possible
2258 to explicit block inheritance of hash by setting __hash__=None at
2259 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2260 level.
2261
Nick Coghlanb028f502008-07-13 14:52:36 +00002262- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2263 the parent module cannot be found while performing an absolute import.
2264 This means that an incorrectly defined __package__ attribute will
2265 now only prevent relative imports in that module rather than causing
2266 all imports from that module to fail.
2267
Nick Coghlan14ff9942008-07-08 14:21:42 +00002268- Issue #2517: Allow unicode messages in Exceptions again by correctly

2278 another thread's dictionary.
2279
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002280- Issue #3004: Minor change to slice.indices(): the start and stop
2281 arguments are now treated identically, making the behaviour easier
2282 to describe and understand. For example, slice(None, -10,
2283 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2284 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2285 10, -1).
2286
Georg Brandl278fc502008-07-19 12:46:12 +00002287- Issue #3219: Calling a function with repeated keyword arguments,
2288 f(a=2, a=23), would not cause a syntax error. This was a regression
2289 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002327- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2328 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002329 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002330 content-length. The problem had been corrected in the 2.4 branch, but never
2331 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002346- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2734
Brett Cannonb61d8012008-05-11 23:39:04 +00002735- ``Lib/lib-old`` is now added to sys.path.
2736
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002737- On MacOS X it is now possible to install the framework in 64-bit
2738 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002739 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002740
2741 This is controlled by the configure argument ``--with-universal-archs``:
2742
2743 - ``--with-universal-archs=all``: install 4-way universal
2744
2745 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2746
2747 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2748
2749 This option should be used in combination with ``--enable-universalsdk=``.
2750
2751 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00002760
2761- The PyString functions have been renamed to PyBytes. A batch of
2762 defines were added so that the linker still sees the original
2763 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002801- Issue #1631171: Re-implement the 'warnings' module in C (the
2802 original Python code has been kept as backup). This will allow for
2803 using the 'warning's machinery in such places as the parser where
2804 use of pure Python code is not possible. Both the ``showarning()``
2805 and ``formatwarning()`` gain an optional 'line' argument which is
2806 not called by default for backwards-compatibility reasons. Setting
2807 ``warnings.showwarning()`` to an implementation that lacks support
2808 for the ``line`` argument will raise a DeprecationWarning.

2832
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002833- The getpass module has been improved on Unix. It now uses /dev/tty
2834 by default and uses stderr instead of stdout. A GetPassWarning is
2835 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002836

Georg Brandl3ee81df2008-05-17 18:14:43 +00002850- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002851 extension modules between 32 and 64 bit platforms. See the distutls

2864 so the controlled environment will more closely mirror the typical
2865 script environment. This supports setup.py scripts that refer to
2866 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002871- Issue #2550: The approach used by client/server code for obtaining
2872 ports to listen on in network-oriented tests has been refined in an
2873 effort to facilitate running multiple instances of the entire
2874 regression test suite in parallel without issue.
2875 test_support.bind_port() has been fixed such that it will always
2876 return a unique port -- which wasn't always the case with the
2877 previous implementation, especially if socket options had been set
2878 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2879 new implementation of bind_port() will actually raise an exception
2880 if it is passed an AF_INET/SOCK_STREAM socket with either the
2881 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2882 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2883 the socket it's been passed. This currently only applies to
2884 Windows. This option prevents any other sockets from binding to the
2885 host/port we've bound to, thus removing the possibility of the
2886 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2887 when a second SOCK_STREAM socket binds and accepts to a host/port
2888 that's already been bound by another socket. The optional preferred
2889 port parameter to bind_port() has been removed. Under no
2890 circumstances should tests be hard coding ports!
2891
2892 test_support.find_unused_port() has also been introduced, which will
2893 pass a temporary socket object to bind_port() in order to obtain an
2894 unused port. The temporary socket object is then closed and
2895 deleted, and the port is returned. This method should only be used
2896 for obtaining an unused port in order to pass to an external program
2897 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2898 a parameter to a server-oriented class that doesn't give you direct
2899 access to the underlying socket used.
2900
2901 Finally, test_support.HOST has been introduced, which should be used
2902 for the host argument of any relevant socket calls (i.e. bind and
2903 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002904
2905 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002906 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002907 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2908 test_asynchat and test_socket_ssl.
2909
Georg Brandl3ee81df2008-05-17 18:14:43 +00002910 It is now possible for multiple instances of the regression test
2911 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00003190- Added the future_builtins module, which contains hex() and oct().
3191 These are the PEP 3127 version of these functions, designed to be
3192 compatible with the hex() and oct() builtins from Python 3.0. They
3193 differ slightly in their output formats from the existing, unchanged
3194 Python 2.6 builtins. The expected usage of the future_builtins
3195 module is:
3196 from future_builtins import hex, oct
3197
Eric Smith7ef40bf2008-02-20 23:34:22 +00003198- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3199 exponents for exponents with absolute value < 100. Follows C99
3200 standard. This is a change on Windows, which would use 3 digits.
3201 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3202 so that any alterations it does to the resulting string will be
3203 available in stringlib/formatter.h (for float.__format__).
3204
Eric Smith5a3c1352008-02-19 13:21:56 +00003205- Implemented PEP 3101, Advanced String Formatting. This adds a new
3206 builtin format(); a format() method for str and unicode; a
3207 __format__() method to object, str, unicode, int, long, float, and
3208 datetime; the class string.Formatter; and the C API
3209 PyObject_Format().
3210
Georg Brandl3ee81df2008-05-17 18:14:43 +00003211- Fixed several potential crashes, all caused by specially crafted
3212 __del__ methods exploiting objects in temporarily inconsistent
3213 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003215- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003216 prevent a possible crash: an Abstract Base Class would try to access
3217 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003222- Clear all free lists during a gc.collect() of the highest generation
3223 in order to allow pymalloc to free more arenas. Python may give back
3224 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003225
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226- Issue #2045: Fix an infinite recursion triggered when printing a
3227 subclass of collections.defaultdict, if its default_factory is set
3228 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003229
Christian Heimesf75dbef2008-02-08 00:11:31 +00003230- Fixed a minor memory leak in dictobject.c. The content of the free
3231 list was not freed on interpreter shutdown.
3232
Georg Brandl5a7eca12010-03-21 19:29:04 +00003233- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00003235
Georg Brandl3ee81df2008-05-17 18:14:43 +00003236- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3237 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003238 to compact the internal free lists of pre-allocted ints and floats.
3239
Georg Brandl3ee81df2008-05-17 18:14:43 +00003240- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3241 calls. Python expected the return type int but the fork familie

3245 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003246
Georg Brandl3ee81df2008-05-17 18:14:43 +00003247- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3248 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3251 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00003253- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3254 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003255
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256- Patch #1473257: generator objects gain a gi_code attribute. This is
3257 the same object as the func_code attribute of the function that
3258 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003259
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260- Issue #1920: "while 0" statements were completely removed by the
3261 compiler, even in the presence of an "else" clause, which is
3262 supposed to be run when the condition is false. Now the compiler
3263 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003264
Guido van Rossumeead05f2008-01-24 18:21:02 +00003265- A few crashers fixed: weakref_in_del.py (issue #1377858);
3266 loosing_dict_ref.py (issue #1303614, test67.py);
3267 borrowed_ref_[34].py (not in tracker).
3268
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003269- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003270 suppressed while an extension is loaded by calling SetErrorMode in
3271 dynload_win.c. The error is still reported properly.
3272
Georg Brandl3ee81df2008-05-17 18:14:43 +00003273- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003274 several extension methods and modules do not work without unicode
3275 support.
3276
Georg Brandl26543b12008-01-21 18:36:51 +00003277- Issue #1882: when compiling code from a string, encoding cookies in the
3278 second line of code were not always recognized correctly.
3279
Georg Brandl14404b62008-01-19 19:27:05 +00003280- Issue #1679: "0x" was taken as a valid integer literal.
3281
Georg Brandl6caad7d2008-01-26 14:19:22 +00003282- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003283 added.
3284
Christian Heimesc94e2b52008-01-14 04:13:37 +00003285- sys.float_info / PyFloat_GetInfo: The floating point information
3286 object was converted from a dict to a specialized structseq object.
3287
Georg Brandl3ee81df2008-05-17 18:14:43 +00003288- Patch #1816: Added sys.flags structseq. It exposes the status of
3289 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003290
Georg Brandl3ee81df2008-05-17 18:14:43 +00003291- Objects/structseq.c: Implemented new structseq representation. The
3292 patch makes structseqs (e.g. the return value of os.stat) more
3293 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003294
Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Patch #1700288: added a type attribute cache that caches method
3296 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003297
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003298- Bug #1776: __import__() no longer accepts filenames on any platform.
3299 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003300
Georg Brandlaed6c662008-01-07 17:25:53 +00003301- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3302
Georg Brandl3ee81df2008-05-17 18:14:43 +00003303- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3304 envvar and sys.dont_write_bytecode attribute. All these can be set
3305 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003306
Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Improve some exception messages when Windows fails to load an
3308 extension module. Now we get for example '%1 is not a valid Win32
3309 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003316- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003317 and INF. float("nan"), float("inf") and float("-inf") now work on
3318 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003319
Georg Brandl3ee81df2008-05-17 18:14:43 +00003320- Compiler now generates simpler and faster code for dictionary
3321 literals. The oparg for BUILD_MAP now indicates an estimated
3322 dictionary size. There is a new opcode, STORE_MAP, for adding
3323 entries to the dictionary.

3335
Nick Coghlanef01d822007-12-03 12:55:17 +00003336- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00003352- Patch #1739468: Directories and zipfiles containing a __main__.py
3353 file can now be directly executed by passing their name to the
3354 interpreter. The directory/zipfile is automatically inserted as the
3355 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003357- Issue #1265: Fix a problem with sys.settrace, if the tracing
3358 function uses a generator expression when at the same time the
3359 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003360
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003361- sets and frozensets now have an isdisjoint() method.
3362
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003363- optimize the performance of builtin.sum().
3364
Neal Norwitz44f326e2007-10-05 05:29:17 +00003365- Fix warnings found by the new version of the Coverity checker.
3366
Georg Brandl5a7eca12010-03-21 19:29:04 +00003367- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003368 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3369 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003370
Georg Brandl3ee81df2008-05-17 18:14:43 +00003371- Issue #1686386: Tuple's tp_repr did not take into account the
3372 possibility of having a self-referential tuple, which is possible
3373 from C code. Nor did object's tp_str consider that a type's tp_str
3374 could do something that could lead to an inifinite recursion.
3375 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3376 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003377
Georg Brandl3ee81df2008-05-17 18:14:43 +00003378- Issue #1164: It was possible to trigger deadlock when using the
3379 'print' statement to write to a file since the GIL was not released
3380 as needed. Now PyObject_Print() does the right thing along with
3381 various tp_print implementations of the built-in types and those in
3382 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003383
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- Issue #1147: Exceptions were directly allowing string exceptions in
3385 their throw() method even though string exceptions no longer
3386 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003387
Georg Brandl3ee81df2008-05-17 18:14:43 +00003388- Issue #1096: Prevent a segfault from getting the repr of a very
3389 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003390
Brett Cannon1e534b52007-09-07 04:18:30 +00003391- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392 PyObject_Call() never calling back out to Python code to trigger
3393 recursion depth updates/checks. Required the creation of a static
3394 RuntimeError instance in case normalizing an exception put the
3395 recursion check value past its limit. Fixes crashers
3396 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003397

Neal Norwitz0ac60192007-05-27 04:08:54 +00003411- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003412 __*__ attributes. (Some already existed, e.g., __doc__ and
3413 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003414
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003415- Add -3 option to the interpreter to warn about features that are
3416 deprecated and will be changed/removed in Python 3.0.
3417
Georg Brandl2134e752007-05-21 20:34:16 +00003418- Patch #1686487: you can now pass any mapping after '**' in function
3419 calls.
3420
Collin Winter62903052007-05-18 23:11:24 +00003421- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003422 "except E as target:". This is to provide forwards compatibility
3423 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00003425- Deprecate BaseException.message as per PEP 352.
3426
Georg Brandl3ee81df2008-05-17 18:14:43 +00003427- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl5a7eca12010-03-21 19:29:04 +00003428 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003429
Vinay Sajip8549ce32007-05-06 17:53:37 +00003430- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003431 setting a plain string, ie don't expand to single letter identifiers.
3432
Raymond Hettinger13936692007-04-11 18:40:58 +00003433- Request #1191699: Slices can now be pickled.
3434
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003435- Request #1193128: str.translate() now allows a None argument for
3436 translations that only remove characters without re-mapping the
3437 remaining characters.
3438
Georg Brandl5cb76c12007-03-21 09:00:39 +00003439- Patch #1682205: a TypeError while unpacking an iterable is no longer
3440 masked by a generic one with the message "unpack non-sequence".
3441
Neal Norwitzaa754b72007-03-21 06:39:48 +00003442- Remove unused file Python/fmod.c.
3443
Guido van Rossum143b5642007-03-23 04:58:42 +00003444- Bug #1683368: The object.__init__() and object.__new__() methods are
3445 now stricter in rejecting excess arguments. The only time when
3446 either allows excess arguments is when it is not overridden and the
3447 other one is. For backwards compatibility, when both are
3448 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003449 warning later). Also, type.__init__() insists on the same signature
3450 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003451
Georg Brandl3ee81df2008-05-17 18:14:43 +00003452- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3453 object to complex using its __complex__() method before falling back
3454 to the __float__() method. Therefore, the functions in the cmath
3455 module now can operate on objects that define a __complex__()
3456 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003458- Patch #1623563: allow __class__ assignment for classes with
3459 __slots__. The old and the new class are still required to have the
3460 same slot names.

3466 ``object.__reduce_ex__()`` is called with an object that is faking
3467 its type.

3473
Georg Brandl7b9c5552007-03-12 14:30:05 +00003474- Bug #1678647: write a newline after printing an exception in any
3475 case, even when converting the value to a string failed.
3476
Georg Brandl871f1bc2007-03-12 13:17:36 +00003477- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003478 its argument, if it exists. If not, it will work like before. This
3479 allows customizing the output of dir() in the presence of a
3480 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00003595- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003613 generator expressions (x for x, in ... ) works again. Fixing this
3614 problem required changing the .pyc magic number. This means that

Facundo Batistad918a652007-04-24 13:54:38 +00004003- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004004 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004045 AttributeError instead of an IOError when the server's response
4046 didn't contain a valid HTTP status line.

4137 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004530 time so that opening a database previously created with the DB_DUP
4531 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4532 opens. Specifically: dictionary assignment to a DB object will
4533 replace all values for a given key when the database allows
4534 duplicate values. DB users should use DB.put(k, v) when they want
4535 to store duplicates; not DB[k] = v.

4544 behavior of quoting dots if they are the second character of any
4545 line.
