Amaury Forgeot d'Arc8530e852008-09-09 07:28:22 +000066 the "-c" and "-m" parameters. Now the behaviour is as expected under Linux,
67 although under Windows it fails at a later point.
Antoine Pitrou5651eaa2008-09-06 20:46:58 +000068
Benjamin Peterson791dc2f2008-09-05 23:27:15 +000069- Issue #3279: Importing site at interpreter was failing silently because the
70 site module uses the open builtin which was not initialized at the time.
71
Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +000072- Issue #3660: Corrected a reference leak in str.encode() when the encoder
73 does not return a bytes object.
74
75- Issue #3774: Added a few more checks in PyTokenizer_FindEncoding to handle
Amaury Forgeot d'Arc1b933ed2008-09-04 22:34:09 +000076 error conditions.
77
Amaury Forgeot d'Arcf0481112008-09-05 20:48:47 +000078- Issue #3594: Fix Parser/tokenizer.c:fp_setreadl() to open the file being
Brett Cannon8a9583e2008-09-04 05:04:25 +000079 tokenized by either a file path or file pointer for the benefit of
80 PyTokenizer_FindEncoding().
81
Antoine Pitroufff95302008-09-03 18:58:51 +000082- Issue #3696: Error parsing arguments on OpenBSD <= 4.4 and Cygwin. On
83 these systems, the mbstowcs() function is slightly buggy and must be
84 replaced with strlen() for the purpose of counting of number of wide
85 characters needed to represent the multi-byte character string.
86
Antoine Pitrou658fad82008-09-03 18:34:34 +000087- Issue #3697: "Fatal Python error: Cannot recover from stack overflow"
88 could be easily encountered under Windows in debug mode when exercising
89 the recursion limit checking code, due to bogus handling of recursion
90 limit when USE_STACKCHEK was enabled.
91
Brett Cannon54bd41d2008-09-02 04:01:42 +000092- Issue 3639: The _warnings module could segfault the interpreter when
93 unexpected types were passed in as arguments.
94
Antoine Pitrouc6b09eb2008-09-01 15:10:14 +000095- Issue #3712: The memoryview object had a reference leak and didn't support
96 cyclic garbage collection.

99 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
100 was correctly parsed but parsing of subsequent arguments failed.
101
Amaury Forgeot d'Arcdb26f7c2008-08-29 07:13:32 +0000102- Issue #3611: An exception __context__ could be cleared in a complex pattern
103 involving a __del__ method re-raising an exception.

Antoine Pitrouec569b72008-08-26 22:40:48 +0000105- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
106 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
107 mechanism. In the process, fix a bug where isinstance() and issubclass(),
108 when given a tuple of classes as second argument, were looking up
109 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
110 type object.
111
Antoine Pitroue2dffc02008-08-26 22:02:58 +0000112- Issue #3663: Py_None was decref'd when printing SyntaxErrors.

165 tkinter.BaseWidget and tkinter.scrolledtext.ScrolledText.
166
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000167- The bsddb module (and therefore the dbm.bsd module) has been removed.
Gregory P. Smith451e99b2008-09-04 04:46:48 +0000168 It is now maintained outside of the standard library at

196 exploitation of poor argument checking.
197
Jesus Cea6ba33292008-08-31 14:12:11 +0000198- bsddb code updated to version 4.7.3pre2. This code is the same than
199 Python 2.6 one, since the intention is to keep an unified 2.x/3.x codebase.
200 The Python code is automatically translated using "2to3". Please, do not
201 update this code in Python 3.0 by hand. Update the 2.6 one and then
202 do "2to3".
203
Benjamin Peterson791dc2f2008-09-05 23:27:15 +0000204- The _bytesio and _stringio modules are now compiled into the python binary.

Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000233Core and Builtins
234-----------------
235
Benjamin Petersonbc74e5b2008-08-23 20:19:17 +0000236- Issue #3653: Fix a segfault when sys.excepthook was called with invalid
237 arguments.
238
Antoine Pitrou616d2852008-08-19 22:09:34 +0000239- Issue #2394: implement more of the memoryview API, with the caveat that
240 only one-dimensional contiguous buffers are supported and exercised right
241 now. Slicing, slice assignment and comparison (equality and inequality)
242 have been added. Also, the tolist() method has been implemented, but only
243 for byte buffers. Endly, the API has been updated to return bytes objects
244 wherever it used to return bytearrays.
245
Antoine Pitrouee58fa42008-08-19 18:22:14 +0000246- Issue #3560: clean up the new C PyMemoryView API so that naming is
247 internally consistent; add macros PyMemoryView_GET_BASE() and
248 PyMemoryView_GET_BUFFER() to access useful properties of a memory views
249 without relying on a particular implementation; remove the ill-named
250 PyMemoryView() function (PyMemoryView_GET_BUFFER() can be used instead).
251
Thomas Hellerf5049fc2008-08-19 19:49:49 +0000252- ctypes function pointers that are COM methods have a boolean True
253 value again.
254
Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000255- Issue #1819: function calls with several named parameters are now on
256 average 35% faster (as measured by pybench).
257
Marc-André Lemburg4cc0f242008-08-07 18:54:33 +0000258- The undocumented C APIs PyUnicode_AsString() and
259 PyUnicode_AsStringAndSize() were made private to the interpreter, in
260 order to be able to refine their interfaces for Python 3.1.
261
262 If you need to access the UTF-8 representation of a Unicode object
263 as bytes string, please use PyUnicode_AsUTF8String() instead.
264
Antoine Pitrouaf14b792008-08-07 21:50:41 +0000265- Issue #3460: PyUnicode_Join() implementation is 10% to 80% faster thanks
266 to Python 3.0's stricter semantics which allow to avoid successive
267 reallocations of the result string (this also affects str.join()).

271-------
272
Hye-Shik Chang50d1f792008-08-23 08:03:03 +0000273- Issue #1276: Added temporary aliases for CJK Mac encodings to resolve
274 a build problem on MacOS with CJK locales. It adds four temporary
275 mappings to existing legacy codecs that are virtually compatible
276 with Mac encodings. They will be replaced by codecs correctly
277 implemented in 3.1.
278
Amaury Forgeot d'Arc41e36672008-08-20 21:35:50 +0000279- Issue #3614: Corrected a typo in xmlrpc.client, leading to a NameError
280 "global name 'header' is not defined".
281
Antoine Pitroufd036452008-08-19 17:56:33 +0000282- Issue #2834: update the regular expression library to match the unicode
283 standards of py3k. In other words, mixing bytes and unicode strings
284 (be it as pattern, search string or replacement string) raises a TypeError.
285 Moreover, the re.UNICODE flag is enabled automatically for unicode patterns,
286 and can be disabled by specifying a new re.ASCII flag; as for bytes
287 patterns, ASCII matching is the only option and trying to specify re.UNICODE
288 for such patterns raises a ValueError.
289
Guido van Rossum52dbbb92008-08-18 21:44:30 +0000290- Issue #3300: make urllib.parse.[un]quote() default to UTF-8.
291 Code contributed by Matt Giuca. quote() now encodes the input
292 before quoting, unquote() decodes after unquoting. There are
293 new arguments to change the encoding and errors settings.
294 There are also new APIs to skip the encode/decode steps.
295 [un]quote_plus() are also affected.
296
Nick Coghlan36f49522008-08-18 12:31:52 +0000297- Issue #2235: numbers.Number now blocks inheritance of the default id()
298 based hash because that hash mechanism is not correct for numeric types.
299 All concrete numeric types that inherit from Number (rather than just
300 registering with it) must explicitly provide a hash implementation in
301 order for their instances to be hashable.
302
Benjamin Peterson4cd6a952008-08-17 20:23:46 +0000303- Issue #2676: in the email package, content-type parsing was hanging on
304 pathological input because of quadratic or exponential behaviour of a
305 regular expression.
306
Antoine Pitrou87695762008-08-14 22:44:29 +0000307- Issue #3476: binary buffered reading through the new "io" library is now
308 thread-safe.
309
Robert Schuppenies3d1c7de2008-08-10 11:28:17 +0000310- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
311 menu entries were not deleted.
312
Lars Gustäbel0c24e8b2008-08-02 11:43:24 +0000313- Remove the TarFileCompat class from tarfile.py.
314
Amaury Forgeot d'Arcbdbddf82008-08-01 00:06:49 +0000315- Issue #2491: os.fdopen is now almost an alias for the built-in open(), and
316 accepts the same parameters. It just checks that its first argument is an
317 integer.
318
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000319- Issue #3394: zipfile.writestr sets external attributes when passed a
320 file name rather than a ZipInfo instance, so files are extracted with
321 mode 0600 rather than 000 under Unix.
322
Antoine Pitrouc66f9092008-07-28 19:46:11 +0000323- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
324 asking for a specific length.

Guido van Rossumf4169812008-03-17 22:56:06 +0000691- A new pickle protocol (protocol 3) is added with explicit support
692 for bytes. This is the default protocol. It intentionally cannot
693 be unpickled by Python 2.x.
694
695- When a pickle written by Python 2.x contains an (8-bit) str
696 instance, this is now decoded to a (Unicode) str instance. The
697 encoding used to do this defaults to ASCII, but can be overridden
698 via two new keyword arguments to the Unpickler class. Previously
699 this would create bytes instances, which is usually wrong: str
700 instances are often used to pickle attribute names etc., and text is
701 more common than binary data anyway.

Martin v. Löwis071ef772008-03-08 11:24:24 +0000703- Default to ASCII as the locale.getpreferredencoding, if the POSIX

712 strings. A new detect_encoding function has been added for
713 determining source file encoding according to PEP-0263. Token
714 sequences returned by tokenize always start with an ENCODING token
715 which specifies the encoding used to decode the file. This token is
716 used to encode the output of untokenize back to bytes.

Georg Brandl52b92cc2008-05-25 09:43:03 +0000893- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
894 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000895
896- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
897
898- Changed `__file__` and `co_filename` to unicode. The path names are decoded
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000899 with `Py_FileSystemDefaultEncoding` and a new API method
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000900 `PyUnicode_DecodeFSDefault(char*)` was added.
901
Georg Brandl52b92cc2008-05-25 09:43:03 +0000902- io.open() and _fileio.FileIO have grown a new argument closefd. A
903 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000904
Georg Brandl52b92cc2008-05-25 09:43:03 +0000905- Added a new option -b to issues warnings (-bb for errors) about
906 certain operations between bytes/buffer and str like str(b'') and
907 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000908
Georg Brandl52b92cc2008-05-25 09:43:03 +0000909- The standards streams sys.stdin, stdout and stderr may be None when
910 the when the C runtime library returns an invalid file descriptor
911 for the streams (fileno(stdin) < 0). For now this happens only for
912 Windows GUI apps and scripts started with `pythonw.exe`.
Christian Heimes58cb1b82007-11-13 02:19:40 +0000913
Christian Heimesbce52be2007-11-17 19:08:41 +0000914- Added PCbuild9 directory for VS 2008.
915
Georg Brandl52b92cc2008-05-25 09:43:03 +0000916- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
917 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000918
Georg Brandl52b92cc2008-05-25 09:43:03 +0000919- Unbound methods are gone for good. ClassObject.method returns an
920 ordinary function object, instance.method still returns a bound
921 method object. The API of bound methods is cleaned up, too. The
922 im_class attribute is removed and im_func + im_self are renamed to
923 __func__ and __self__. The factory PyMethod_New takes only func and
924 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000925
Georg Brandl52b92cc2008-05-25 09:43:03 +0000926- intobject.h is no longer included by Python.h. The remains were
927 moved to longobject.h. It still exists to define several aliases
928 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000929
Christian Heimesa37d4c62007-12-04 23:02:19 +0000930- Removed sys.maxint, use sys.maxsize instead.

938-------
939
Georg Brandl52b92cc2008-05-25 09:43:03 +0000940- When loading an external file using testfile(), the passed-in
941 encoding argument was being ignored if __loader__ is defined and
942 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000943
Georg Brandl52b92cc2008-05-25 09:43:03 +0000944- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
945 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000946
Christian Heimesc9543e42007-11-28 08:28:28 +0000947- Removed the 'new' module.
948
Georg Brandl52b92cc2008-05-25 09:43:03 +0000949- Removed all types from the 'types' module that are easily accessable
950 through builtins.

Neal Norwitz4886cc32006-08-21 17:06:07 +0000957
958Core and Builtins
959-----------------
960
Martin v. Löwis47383402007-08-15 07:32:56 +0000961- PEP 3131: Support non-ASCII identifiers.
962
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000963- PEP 3120: Change default encoding to UTF-8.
964
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000965- PEP 3123: Use proper C inheritance for PyObject.
966
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000967- Removed the __oct__ and __hex__ special methods and added a bin()
968 builtin function.
969
Georg Brandl52b92cc2008-05-25 09:43:03 +0000970- PEP 3127: octal literals now start with "0o". Old-style octal
971 literals are invalid. There are binary literals with a prefix of
972 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000973
Guido van Rossume7ba4952007-06-06 23:52:48 +0000974- None, True, False are now keywords.
975
Guido van Rossum29478ef2007-05-29 00:39:44 +0000976- PEP 3119: isinstance() and issubclass() can be overridden.
977
Guido van Rossumebe3e162007-05-17 18:20:34 +0000978- Remove BaseException.message.
979
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000980- Remove tuple parameter unpacking (PEP 3113).
981
Georg Brandl52b92cc2008-05-25 09:43:03 +0000982- Remove the f_restricted attribute from frames. This naturally leads
983 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000984
Georg Brandl52b92cc2008-05-25 09:43:03 +0000985- PEP 3132 was accepted. That means that you can do ``a, *b =
986 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +0000987
Georg Brandl52b92cc2008-05-25 09:43:03 +0000988- range() now returns an iterator rather than a list. Floats are not
989 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +0000990
Nick Coghlan650f0d02007-04-15 12:05:43 +0000991- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +0000992 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +0000993
Guido van Rossume27dc722007-03-27 22:37:34 +0000994- By default, != returns the opposite of ==, unless the latter returns
995 NotImplemented.
996
Georg Brandl52b92cc2008-05-25 09:43:03 +0000997- Patch #1680961: sys.exitfunc has been removed and replaced with a
998 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +0000999
Georg Brandl801dd732007-03-18 20:18:31 +00001000- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +00001001 keyword arg in the class statement, which can now use the full
1002 syntax of a parameter list. Also, the metaclass can implement a
1003 __prepare__ function which will be called to create the dictionary
1004 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +00001005
Georg Brandl428f0642007-03-18 18:35:15 +00001006- The long-deprecated argument "pend" of PyFloat_FromString() has been
1007 removed.
1008
Georg Brandle32b4222007-03-10 22:13:27 +00001009- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +00001010 its argument, if it exists. If not, it will work like before. This
1011 allows customizing the output of dir() in the presence of a
1012 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +00001013
Neal Norwitz8dfc4a92007-08-11 06:39:53 +00001014- Removed support for __members__ and __methods__.
1015
Georg Brandle32b4222007-03-10 22:13:27 +00001016- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +00001017
Georg Brandle32b4222007-03-10 22:13:27 +00001018- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001019 functionality formerly known as raw_input(); the name raw_input() is
1020 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +00001021
Georg Brandl52b92cc2008-05-25 09:43:03 +00001022- Classes listed in an 'except' clause must inherit from
1023 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +00001024
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001025- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +00001026 and .keys(), .items(), .values() return dict views, which behave
1027 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001028
Guido van Rossum8b545362007-02-09 23:52:14 +00001029- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001030 'softspace' attribute of files is now gone (since print() doesn't
1031 use it). A side effect of this change is that you can get
1032 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +00001033
1034 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +00001035 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +00001036
1037 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +00001038
Brett Cannon398db8b2007-01-29 23:44:37 +00001039- PEP 3102: keyword-only arguments.
1040
Georg Brandl52b92cc2008-05-25 09:43:03 +00001041- Int/Long unification is complete. The 'long' built-in type and
1042 literals with trailing 'L' or 'l' have been removed. Performance
1043 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +00001044
1045- 'except E, V' must now be spelled as 'except E as V' and deletes V
1046 at the end of the except clause; V must be a simple name.
1047
Neal Norwitzc1505362006-12-28 06:47:50 +00001048- Added function annotations per PEP 3107.
1049
Georg Brandl52b92cc2008-05-25 09:43:03 +00001050- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +00001051
1052 >>> def f(x):
1053 ... def inc():
1054 ... nonlocal x
1055 ... x += 1
1056 ... return x
1057 ... return inc
1058 ...
1059 >>> inc = f(0)
1060 >>> inc()
1061 1
1062 >>> inc()
1063 2
1064
Georg Brandl66a796e2006-12-19 20:50:34 +00001065- Moved intern() to sys.intern().
1066
1067- exec is now a function.
1068
1069- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +00001070
Neal Norwitz4886cc32006-08-21 17:06:07 +00001071- Classic classes are a thing of the past. All classes are new style.
1072
1073- Exceptions *must* derive from BaseException.
1074
1075- Integer division always returns a float. The -Q option is no more.
1076 All the following are gone:
1077 * PyNumber_Divide and PyNumber_InPlaceDivide
1078 * __div__, __rdiv__, and __idiv__
1079 * nb_divide, nb_inplace_divide
1080 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
1081 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
1082 if we want to re-use __div__ and friends. If we do, it will make
1083 it harder to write code for both 2.x and 3.x.)
1084
1085- 'as' and 'with' are keywords.
1086
1087- Absolute import is the default behavior for 'import foo' etc.
1088
Georg Brandl52b92cc2008-05-25 09:43:03 +00001089- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001090
Georg Brandl52b92cc2008-05-25 09:43:03 +00001091- Removed these Python builtins: apply(), callable(), coerce(),
1092 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +00001093
Georg Brandl52b92cc2008-05-25 09:43:03 +00001094- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001095
Georg Brandl52b92cc2008-05-25 09:43:03 +00001096- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001097
1098- Remove C API support for restricted execution.
1099
Guido van Rossumcf1be882007-08-30 22:07:17 +00001100- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +00001101 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +00001102 sequences of unequal length -- it now stops after the shortest one
1103 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001104
Georg Brandl52b92cc2008-05-25 09:43:03 +00001105- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001106
1107- Added class decorators per PEP 3129.

Martin v. Löwis967f1e32007-08-14 09:23:10 +00001142 Remove string.{letters, lowercase, uppercase}.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001143
Georg Brandl52b92cc2008-05-25 09:43:03 +00001144- Removed support for long obsolete platforms: plat-aix3, plat-irix5.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001145
Georg Brandl52b92cc2008-05-25 09:43:03 +00001146- Removed xmlrpclib.SlowParser. It was based on xmllib.
