Amaury Forgeot d'Arc8530e852008-09-09 07:28:22 +000053 the "-c" and "-m" parameters. Now the behaviour is as expected under Linux,
54 although under Windows it fails at a later point.
Antoine Pitrou5651eaa2008-09-06 20:46:58 +000055
Benjamin Peterson791dc2f2008-09-05 23:27:15 +000056- Issue #3279: Importing site at interpreter was failing silently because the
57 site module uses the open builtin which was not initialized at the time.
58
Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +000059- Issue #3660: Corrected a reference leak in str.encode() when the encoder

Brett Cannon8a9583e2008-09-04 05:04:25 +000066 tokenized by either a file path or file pointer for the benefit of
67 PyTokenizer_FindEncoding().
68
Antoine Pitroufff95302008-09-03 18:58:51 +000069- Issue #3696: Error parsing arguments on OpenBSD <= 4.4 and Cygwin. On
70 these systems, the mbstowcs() function is slightly buggy and must be
71 replaced with strlen() for the purpose of counting of number of wide
72 characters needed to represent the multi-byte character string.
73
Antoine Pitrou658fad82008-09-03 18:34:34 +000074- Issue #3697: "Fatal Python error: Cannot recover from stack overflow"

77 limit when USE_STACKCHEK was enabled.
78
Brett Cannon54bd41d2008-09-02 04:01:42 +000079- Issue 3639: The _warnings module could segfault the interpreter when

87 was correctly parsed but parsing of subsequent arguments failed.
88
Amaury Forgeot d'Arcdb26f7c2008-08-29 07:13:32 +000089- Issue #3611: An exception __context__ could be cleared in a complex pattern

93 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
94 mechanism. In the process, fix a bug where isinstance() and issubclass(),
95 when given a tuple of classes as second argument, were looking up
96 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
97 type object.
98
Antoine Pitroue2dffc02008-08-26 22:02:58 +000099- Issue #3663: Py_None was decref'd when printing SyntaxErrors.

Guilherme Polob212b752008-09-04 11:21:31 +0000151- Issue #1658: tkinter changes dict size during iteration in both
152 tkinter.BaseWidget and tkinter.scrolledtext.ScrolledText.
153
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000154- The bsddb module (and therefore the dbm.bsd module) has been removed.
Gregory P. Smith451e99b2008-09-04 04:46:48 +0000155 It is now maintained outside of the standard library at
156 http://www.jcea.es/programacion/pybsddb.htm.
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000157
Facundo Batistac469d4c2008-09-03 22:49:01 +0000158- Issue 600362: Relocated parse_qs() and parse_qsl(), from the cgi module

183 exploitation of poor argument checking.
184
Jesus Cea6ba33292008-08-31 14:12:11 +0000185- bsddb code updated to version 4.7.3pre2. This code is the same than
186 Python 2.6 one, since the intention is to keep an unified 2.x/3.x codebase.
187 The Python code is automatically translated using "2to3". Please, do not
188 update this code in Python 3.0 by hand. Update the 2.6 one and then
189 do "2to3".
190
Benjamin Peterson791dc2f2008-09-05 23:27:15 +0000191- The _bytesio and _stringio modules are now compiled into the python binary.
192
Gregory P. Smith693fc462008-09-06 20:13:06 +0000193- Issue #3492 and #3790: Fixed the zlib module and zipimport module uses of
194 mutable bytearray objects where they should have been using immutable bytes.

221-----------------
222
Benjamin Petersonbc74e5b2008-08-23 20:19:17 +0000223- Issue #3653: Fix a segfault when sys.excepthook was called with invalid
224 arguments.
225
Antoine Pitrou616d2852008-08-19 22:09:34 +0000226- Issue #2394: implement more of the memoryview API, with the caveat that
227 only one-dimensional contiguous buffers are supported and exercised right
228 now. Slicing, slice assignment and comparison (equality and inequality)
229 have been added. Also, the tolist() method has been implemented, but only
230 for byte buffers. Endly, the API has been updated to return bytes objects
231 wherever it used to return bytearrays.
232
Antoine Pitrouee58fa42008-08-19 18:22:14 +0000233- Issue #3560: clean up the new C PyMemoryView API so that naming is
234 internally consistent; add macros PyMemoryView_GET_BASE() and
235 PyMemoryView_GET_BUFFER() to access useful properties of a memory views
236 without relying on a particular implementation; remove the ill-named
237 PyMemoryView() function (PyMemoryView_GET_BUFFER() can be used instead).
238
Thomas Hellerf5049fc2008-08-19 19:49:49 +0000239- ctypes function pointers that are COM methods have a boolean True
240 value again.
241
Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000242- Issue #1819: function calls with several named parameters are now on
243 average 35% faster (as measured by pybench).
244
Marc-André Lemburg4cc0f242008-08-07 18:54:33 +0000245- The undocumented C APIs PyUnicode_AsString() and
246 PyUnicode_AsStringAndSize() were made private to the interpreter, in
247 order to be able to refine their interfaces for Python 3.1.
248
249 If you need to access the UTF-8 representation of a Unicode object
250 as bytes string, please use PyUnicode_AsUTF8String() instead.
251
Antoine Pitrouaf14b792008-08-07 21:50:41 +0000252- Issue #3460: PyUnicode_Join() implementation is 10% to 80% faster thanks
253 to Python 3.0's stricter semantics which allow to avoid successive
254 reallocations of the result string (this also affects str.join()).

258-------
259
Hye-Shik Chang50d1f792008-08-23 08:03:03 +0000260- Issue #1276: Added temporary aliases for CJK Mac encodings to resolve
261 a build problem on MacOS with CJK locales. It adds four temporary
262 mappings to existing legacy codecs that are virtually compatible
263 with Mac encodings. They will be replaced by codecs correctly
264 implemented in 3.1.
265
Amaury Forgeot d'Arc41e36672008-08-20 21:35:50 +0000266- Issue #3614: Corrected a typo in xmlrpc.client, leading to a NameError
267 "global name 'header' is not defined".
268
Antoine Pitroufd036452008-08-19 17:56:33 +0000269- Issue #2834: update the regular expression library to match the unicode
270 standards of py3k. In other words, mixing bytes and unicode strings
271 (be it as pattern, search string or replacement string) raises a TypeError.
272 Moreover, the re.UNICODE flag is enabled automatically for unicode patterns,
273 and can be disabled by specifying a new re.ASCII flag; as for bytes
274 patterns, ASCII matching is the only option and trying to specify re.UNICODE
275 for such patterns raises a ValueError.
276
Guido van Rossum52dbbb92008-08-18 21:44:30 +0000277- Issue #3300: make urllib.parse.[un]quote() default to UTF-8.
278 Code contributed by Matt Giuca. quote() now encodes the input
279 before quoting, unquote() decodes after unquoting. There are
280 new arguments to change the encoding and errors settings.
281 There are also new APIs to skip the encode/decode steps.
282 [un]quote_plus() are also affected.
283
Nick Coghlan36f49522008-08-18 12:31:52 +0000284- Issue #2235: numbers.Number now blocks inheritance of the default id()
285 based hash because that hash mechanism is not correct for numeric types.
286 All concrete numeric types that inherit from Number (rather than just
287 registering with it) must explicitly provide a hash implementation in
288 order for their instances to be hashable.
289
Benjamin Peterson4cd6a952008-08-17 20:23:46 +0000290- Issue #2676: in the email package, content-type parsing was hanging on
291 pathological input because of quadratic or exponential behaviour of a
292 regular expression.
293
Antoine Pitrou87695762008-08-14 22:44:29 +0000294- Issue #3476: binary buffered reading through the new "io" library is now
295 thread-safe.
296
Robert Schuppenies3d1c7de2008-08-10 11:28:17 +0000297- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
298 menu entries were not deleted.
299
Lars Gustäbel0c24e8b2008-08-02 11:43:24 +0000300- Remove the TarFileCompat class from tarfile.py.
301
Amaury Forgeot d'Arcbdbddf82008-08-01 00:06:49 +0000302- Issue #2491: os.fdopen is now almost an alias for the built-in open(), and
303 accepts the same parameters. It just checks that its first argument is an
304 integer.
305
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000306- Issue #3394: zipfile.writestr sets external attributes when passed a
307 file name rather than a ZipInfo instance, so files are extracted with
308 mode 0600 rather than 000 under Unix.
309
Antoine Pitrouc66f9092008-07-28 19:46:11 +0000310- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
311 asking for a specific length.

Guido van Rossumf4169812008-03-17 22:56:06 +0000678- A new pickle protocol (protocol 3) is added with explicit support
679 for bytes. This is the default protocol. It intentionally cannot
680 be unpickled by Python 2.x.
681
682- When a pickle written by Python 2.x contains an (8-bit) str
683 instance, this is now decoded to a (Unicode) str instance. The
684 encoding used to do this defaults to ASCII, but can be overridden
685 via two new keyword arguments to the Unpickler class. Previously
686 this would create bytes instances, which is usually wrong: str
687 instances are often used to pickle attribute names etc., and text is
688 more common than binary data anyway.
689
Martin v. Löwis071ef772008-03-08 11:24:24 +0000690- Default to ASCII as the locale.getpreferredencoding, if the POSIX

698 has been renamed tokenize and now works with bytes rather than
699 strings. A new detect_encoding function has been added for
700 determining source file encoding according to PEP-0263. Token
701 sequences returned by tokenize always start with an ENCODING token
702 which specifies the encoding used to decode the file. This token is
703 used to encode the output of untokenize back to bytes.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000874- Comparisons between str and str8 now return False/True for ==/!=.
875 sqlite3 returns str8 when recreating on object from it's __conform__
876 value. The struct module returns str8 for all string-related
877 formats. This was true before this change, but becomes more
878 apparent thanks to string comparisons always being False.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000889- io.open() and _fileio.FileIO have grown a new argument closefd. A
890 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000891
Georg Brandl52b92cc2008-05-25 09:43:03 +0000892- Added a new option -b to issues warnings (-bb for errors) about
893 certain operations between bytes/buffer and str like str(b'') and
894 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000895
Georg Brandl52b92cc2008-05-25 09:43:03 +0000896- The standards streams sys.stdin, stdout and stderr may be None when
897 the when the C runtime library returns an invalid file descriptor
898 for the streams (fileno(stdin) < 0). For now this happens only for
899 Windows GUI apps and scripts started with `pythonw.exe`.
Christian Heimes58cb1b82007-11-13 02:19:40 +0000900
Christian Heimesbce52be2007-11-17 19:08:41 +0000901- Added PCbuild9 directory for VS 2008.
902
Georg Brandl52b92cc2008-05-25 09:43:03 +0000903- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
904 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000905
Georg Brandl52b92cc2008-05-25 09:43:03 +0000906- Unbound methods are gone for good. ClassObject.method returns an
907 ordinary function object, instance.method still returns a bound
908 method object. The API of bound methods is cleaned up, too. The
909 im_class attribute is removed and im_func + im_self are renamed to
910 __func__ and __self__. The factory PyMethod_New takes only func and
911 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000912
Georg Brandl52b92cc2008-05-25 09:43:03 +0000913- intobject.h is no longer included by Python.h. The remains were
914 moved to longobject.h. It still exists to define several aliases
915 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000916
Christian Heimesa37d4c62007-12-04 23:02:19 +0000917- Removed sys.maxint, use sys.maxsize instead.

926
Georg Brandl52b92cc2008-05-25 09:43:03 +0000927- When loading an external file using testfile(), the passed-in
928 encoding argument was being ignored if __loader__ is defined and
929 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000930
Georg Brandl52b92cc2008-05-25 09:43:03 +0000931- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
932 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000933
Christian Heimesc9543e42007-11-28 08:28:28 +0000934- Removed the 'new' module.
935
Georg Brandl52b92cc2008-05-25 09:43:03 +0000936- Removed all types from the 'types' module that are easily accessable
937 through builtins.

Neal Norwitz4886cc32006-08-21 17:06:07 +0000944
945Core and Builtins
946-----------------
947
Martin v. Löwis47383402007-08-15 07:32:56 +0000948- PEP 3131: Support non-ASCII identifiers.
949
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000950- PEP 3120: Change default encoding to UTF-8.
951
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000952- PEP 3123: Use proper C inheritance for PyObject.
953
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000954- Removed the __oct__ and __hex__ special methods and added a bin()
955 builtin function.
956
Georg Brandl52b92cc2008-05-25 09:43:03 +0000957- PEP 3127: octal literals now start with "0o". Old-style octal
958 literals are invalid. There are binary literals with a prefix of
959 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000960
Guido van Rossume7ba4952007-06-06 23:52:48 +0000961- None, True, False are now keywords.
962
Guido van Rossum29478ef2007-05-29 00:39:44 +0000963- PEP 3119: isinstance() and issubclass() can be overridden.
964
Guido van Rossumebe3e162007-05-17 18:20:34 +0000965- Remove BaseException.message.
966
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000967- Remove tuple parameter unpacking (PEP 3113).
968
Georg Brandl52b92cc2008-05-25 09:43:03 +0000969- Remove the f_restricted attribute from frames. This naturally leads
970 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000971
Georg Brandl52b92cc2008-05-25 09:43:03 +0000972- PEP 3132 was accepted. That means that you can do ``a, *b =
973 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000974
Georg Brandl52b92cc2008-05-25 09:43:03 +0000975- range() now returns an iterator rather than a list. Floats are not
976 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000977
Nick Coghlan650f0d02007-04-15 12:05:43 +0000978- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000979 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000980
Guido van Rossume27dc722007-03-27 22:37:34 +0000981- By default, != returns the opposite of ==, unless the latter returns
982 NotImplemented.
983
Georg Brandl52b92cc2008-05-25 09:43:03 +0000984- Patch #1680961: sys.exitfunc has been removed and replaced with a
985 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +0000986
Georg Brandl801dd732007-03-18 20:18:31 +0000987- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +0000988 keyword arg in the class statement, which can now use the full
989 syntax of a parameter list. Also, the metaclass can implement a
990 __prepare__ function which will be called to create the dictionary
991 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +0000992
Georg Brandl428f0642007-03-18 18:35:15 +0000993- The long-deprecated argument "pend" of PyFloat_FromString() has been
994 removed.
995
Georg Brandle32b4222007-03-10 22:13:27 +0000996- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +0000997 its argument, if it exists. If not, it will work like before. This
998 allows customizing the output of dir() in the presence of a
999 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +00001000
Neal Norwitz8dfc4a92007-08-11 06:39:53 +00001001- Removed support for __members__ and __methods__.
1002
Georg Brandle32b4222007-03-10 22:13:27 +00001003- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +00001004
Georg Brandle32b4222007-03-10 22:13:27 +00001005- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001006 functionality formerly known as raw_input(); the name raw_input() is
1007 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +00001008
Georg Brandl52b92cc2008-05-25 09:43:03 +00001009- Classes listed in an 'except' clause must inherit from
1010 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +00001011
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001012- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +00001013 and .keys(), .items(), .values() return dict views, which behave
1014 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001015
Guido van Rossum8b545362007-02-09 23:52:14 +00001016- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001017 'softspace' attribute of files is now gone (since print() doesn't
1018 use it). A side effect of this change is that you can get
1019 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +00001020
1021 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +00001022 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +00001023
1024 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +00001025
Brett Cannon398db8b2007-01-29 23:44:37 +00001026- PEP 3102: keyword-only arguments.
1027
Georg Brandl52b92cc2008-05-25 09:43:03 +00001028- Int/Long unification is complete. The 'long' built-in type and
1029 literals with trailing 'L' or 'l' have been removed. Performance
1030 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +00001031
1032- 'except E, V' must now be spelled as 'except E as V' and deletes V
1033 at the end of the except clause; V must be a simple name.
1034
Neal Norwitzc1505362006-12-28 06:47:50 +00001035- Added function annotations per PEP 3107.
1036
Georg Brandl52b92cc2008-05-25 09:43:03 +00001037- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +00001038
1039 >>> def f(x):
1040 ... def inc():
1041 ... nonlocal x
1042 ... x += 1
1043 ... return x
1044 ... return inc
1045 ...
1046 >>> inc = f(0)
1047 >>> inc()
1048 1
1049 >>> inc()
1050 2
1051
Georg Brandl66a796e2006-12-19 20:50:34 +00001052- Moved intern() to sys.intern().
1053
1054- exec is now a function.
1055
1056- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +00001057
Neal Norwitz4886cc32006-08-21 17:06:07 +00001058- Classic classes are a thing of the past. All classes are new style.
1059
1060- Exceptions *must* derive from BaseException.
1061
1062- Integer division always returns a float. The -Q option is no more.
1063 All the following are gone:
1064 * PyNumber_Divide and PyNumber_InPlaceDivide
1065 * __div__, __rdiv__, and __idiv__
1066 * nb_divide, nb_inplace_divide
1067 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
1068 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
1069 if we want to re-use __div__ and friends. If we do, it will make
1070 it harder to write code for both 2.x and 3.x.)
1071
1072- 'as' and 'with' are keywords.
1073
1074- Absolute import is the default behavior for 'import foo' etc.
1075
Georg Brandl52b92cc2008-05-25 09:43:03 +00001076- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001077
Georg Brandl52b92cc2008-05-25 09:43:03 +00001078- Removed these Python builtins: apply(), callable(), coerce(),
1079 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +00001080
Georg Brandl52b92cc2008-05-25 09:43:03 +00001081- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001082
Georg Brandl52b92cc2008-05-25 09:43:03 +00001083- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001084
1085- Remove C API support for restricted execution.
1086
Guido van Rossumcf1be882007-08-30 22:07:17 +00001087- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +00001088 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +00001089 sequences of unequal length -- it now stops after the shortest one
1090 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001091
Georg Brandl52b92cc2008-05-25 09:43:03 +00001092- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001093
1094- Added class decorators per PEP 3129.

Guido van Rossumd59da4b2007-05-22 18:11:13 +00001130
Georg Brandl52b92cc2008-05-25 09:43:03 +00001131- Removed support for long obsolete platforms: plat-aix3, plat-irix5.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001132
Georg Brandl52b92cc2008-05-25 09:43:03 +00001133- Removed xmlrpclib.SlowParser. It was based on xmllib.
