Benjamin Peterson791dc2f2008-09-05 23:27:15 +0000109- Issue #3279: Importing site at interpreter was failing silently because the
110 site module uses the open builtin which was not initialized at the time.

Brett Cannon8a9583e2008-09-04 05:04:25 +0000119 tokenized by either a file path or file pointer for the benefit of
120 PyTokenizer_FindEncoding().
121
Antoine Pitroufff95302008-09-03 18:58:51 +0000122- Issue #3696: Error parsing arguments on OpenBSD <= 4.4 and Cygwin. On

125 characters needed to represent the multi-byte character string.
126
Antoine Pitrou658fad82008-09-03 18:34:34 +0000127- Issue #3697: "Fatal Python error: Cannot recover from stack overflow"

146 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
147 mechanism. In the process, fix a bug where isinstance() and issubclass(),
148 when given a tuple of classes as second argument, were looking up
149 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
150 type object.

206
Benjamin Peterson6ba23322008-09-03 22:59:38 +0000207- The bsddb module (and therefore the dbm.bsd module) has been removed.
Gregory P. Smith451e99b2008-09-04 04:46:48 +0000208 It is now maintained outside of the standard library at

274-----------------
275
Benjamin Petersonbc74e5b2008-08-23 20:19:17 +0000276- Issue #3653: Fix a segfault when sys.excepthook was called with invalid
277 arguments.
278
Antoine Pitrou616d2852008-08-19 22:09:34 +0000279- Issue #2394: implement more of the memoryview API, with the caveat that
280 only one-dimensional contiguous buffers are supported and exercised right
281 now. Slicing, slice assignment and comparison (equality and inequality)
282 have been added. Also, the tolist() method has been implemented, but only
283 for byte buffers. Endly, the API has been updated to return bytes objects
284 wherever it used to return bytearrays.
285
Antoine Pitrouee58fa42008-08-19 18:22:14 +0000286- Issue #3560: clean up the new C PyMemoryView API so that naming is
287 internally consistent; add macros PyMemoryView_GET_BASE() and
288 PyMemoryView_GET_BUFFER() to access useful properties of a memory views
289 without relying on a particular implementation; remove the ill-named
290 PyMemoryView() function (PyMemoryView_GET_BUFFER() can be used instead).
291
Thomas Hellerf5049fc2008-08-19 19:49:49 +0000292- ctypes function pointers that are COM methods have a boolean True
293 value again.
294
Antoine Pitrou9a2310d2008-07-25 22:39:39 +0000295- Issue #1819: function calls with several named parameters are now on
296 average 35% faster (as measured by pybench).
297
Marc-André Lemburg4cc0f242008-08-07 18:54:33 +0000298- The undocumented C APIs PyUnicode_AsString() and
299 PyUnicode_AsStringAndSize() were made private to the interpreter, in
300 order to be able to refine their interfaces for Python 3.1.
301
302 If you need to access the UTF-8 representation of a Unicode object
303 as bytes string, please use PyUnicode_AsUTF8String() instead.
304
Antoine Pitrouaf14b792008-08-07 21:50:41 +0000305- Issue #3460: PyUnicode_Join() implementation is 10% to 80% faster thanks
306 to Python 3.0's stricter semantics which allow to avoid successive
307 reallocations of the result string (this also affects str.join()).

Hye-Shik Chang50d1f792008-08-23 08:03:03 +0000313- Issue #1276: Added temporary aliases for CJK Mac encodings to resolve
314 a build problem on MacOS with CJK locales. It adds four temporary
315 mappings to existing legacy codecs that are virtually compatible
316 with Mac encodings. They will be replaced by codecs correctly
317 implemented in 3.1.
318
Amaury Forgeot d'Arc41e36672008-08-20 21:35:50 +0000319- Issue #3614: Corrected a typo in xmlrpc.client, leading to a NameError
320 "global name 'header' is not defined".

Antoine Pitroufd036452008-08-19 17:56:33 +0000322- Issue #2834: update the regular expression library to match the unicode
323 standards of py3k. In other words, mixing bytes and unicode strings
324 (be it as pattern, search string or replacement string) raises a TypeError.
325 Moreover, the re.UNICODE flag is enabled automatically for unicode patterns,
326 and can be disabled by specifying a new re.ASCII flag; as for bytes
327 patterns, ASCII matching is the only option and trying to specify re.UNICODE
328 for such patterns raises a ValueError.
329
Guido van Rossum52dbbb92008-08-18 21:44:30 +0000330- Issue #3300: make urllib.parse.[un]quote() default to UTF-8.
331 Code contributed by Matt Giuca. quote() now encodes the input
332 before quoting, unquote() decodes after unquoting. There are
333 new arguments to change the encoding and errors settings.
334 There are also new APIs to skip the encode/decode steps.
335 [un]quote_plus() are also affected.
336
Nick Coghlan36f49522008-08-18 12:31:52 +0000337- Issue #2235: numbers.Number now blocks inheritance of the default id()
338 based hash because that hash mechanism is not correct for numeric types.
339 All concrete numeric types that inherit from Number (rather than just
340 registering with it) must explicitly provide a hash implementation in
341 order for their instances to be hashable.
342
Benjamin Peterson4cd6a952008-08-17 20:23:46 +0000343- Issue #2676: in the email package, content-type parsing was hanging on
344 pathological input because of quadratic or exponential behaviour of a
345 regular expression.
346
Antoine Pitrou87695762008-08-14 22:44:29 +0000347- Issue #3476: binary buffered reading through the new "io" library is now

354
Amaury Forgeot d'Arcbdbddf82008-08-01 00:06:49 +0000355- Issue #2491: os.fdopen is now almost an alias for the built-in open(), and
356 accepts the same parameters. It just checks that its first argument is an
357 integer.
358
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000359- Issue #3394: zipfile.writestr sets external attributes when passed a
360 file name rather than a ZipInfo instance, so files are extracted with
361 mode 0600 rather than 000 under Unix.
362
Antoine Pitrouc66f9092008-07-28 19:46:11 +0000363- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
364 asking for a specific length.

Guido van Rossumf4169812008-03-17 22:56:06 +0000731- A new pickle protocol (protocol 3) is added with explicit support
732 for bytes. This is the default protocol. It intentionally cannot
733 be unpickled by Python 2.x.
734
735- When a pickle written by Python 2.x contains an (8-bit) str
736 instance, this is now decoded to a (Unicode) str instance. The
737 encoding used to do this defaults to ASCII, but can be overridden
738 via two new keyword arguments to the Unpickler class. Previously
739 this would create bytes instances, which is usually wrong: str
740 instances are often used to pickle attribute names etc., and text is
741 more common than binary data anyway.
742
Martin v. Löwis071ef772008-03-08 11:24:24 +0000743- Default to ASCII as the locale.getpreferredencoding, if the POSIX

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

Georg Brandl52b92cc2008-05-25 09:43:03 +0000901- Renamed --enable-unicode configure flag to --with-wide-unicode,
902 since Unicode strings can't be disabled anymore.

909
Georg Brandl52b92cc2008-05-25 09:43:03 +0000910- New API PyImport_ImportModuleNoBlock(), works like

Fred Drake0e474a82007-10-11 18:01:43 +0000915What's New in Python 3.0a2?
Christian Heimesbc873412007-12-08 22:11:32 +0000916===========================
Fred Drake0e474a82007-10-11 18:01:43 +0000917
Guido van Rossum99533a92007-12-06 05:07:41 +0000918*Release date: 07-Dec-2007*
919
920(Note: this list is incomplete.)
Fred Drake0e474a82007-10-11 18:01:43 +0000921
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000922Core and Builtins
923-----------------
924
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000925- str8 now has the same construction signature as bytes.
926
Georg Brandl52b92cc2008-05-25 09:43:03 +0000927- Comparisons between str and str8 now return False/True for ==/!=.
928 sqlite3 returns str8 when recreating on object from it's __conform__
929 value. The struct module returns str8 for all string-related
930 formats. This was true before this change, but becomes more
931 apparent thanks to string comparisons always being False.
Brett Cannon40430012007-10-22 20:24:51 +0000932
Georg Brandl52b92cc2008-05-25 09:43:03 +0000933- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode,
934 buffer, encoding, newline)`.
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000935
936- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
937
938- Changed `__file__` and `co_filename` to unicode. The path names are decoded
Antoine Pitrou6e1df8d2008-07-25 19:58:18 +0000939 with `Py_FileSystemDefaultEncoding` and a new API method
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000940 `PyUnicode_DecodeFSDefault(char*)` was added.
941
Georg Brandl52b92cc2008-05-25 09:43:03 +0000942- io.open() and _fileio.FileIO have grown a new argument closefd. A
943 false value disables the closing of the file descriptor.
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000944
Georg Brandl52b92cc2008-05-25 09:43:03 +0000945- Added a new option -b to issues warnings (-bb for errors) about
946 certain operations between bytes/buffer and str like str(b'') and
947 comparison.
Guido van Rossum98297ee2007-11-06 21:34:58 +0000948
Georg Brandl52b92cc2008-05-25 09:43:03 +0000949- The standards streams sys.stdin, stdout and stderr may be None when
950 the when the C runtime library returns an invalid file descriptor
951 for the streams (fileno(stdin) < 0). For now this happens only for
952 Windows GUI apps and scripts started with `pythonw.exe`.
Christian Heimes58cb1b82007-11-13 02:19:40 +0000953
Christian Heimesbce52be2007-11-17 19:08:41 +0000954- Added PCbuild9 directory for VS 2008.
955
Georg Brandl52b92cc2008-05-25 09:43:03 +0000956- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to
957 work around a name clash with VS 2008 on Windows.
Christian Heimesbce52be2007-11-17 19:08:41 +0000958
Georg Brandl52b92cc2008-05-25 09:43:03 +0000959- Unbound methods are gone for good. ClassObject.method returns an
960 ordinary function object, instance.method still returns a bound
961 method object. The API of bound methods is cleaned up, too. The
962 im_class attribute is removed and im_func + im_self are renamed to
963 __func__ and __self__. The factory PyMethod_New takes only func and
964 instance as argument.
Christian Heimesff737952007-11-27 10:40:20 +0000965
Georg Brandl52b92cc2008-05-25 09:43:03 +0000966- intobject.h is no longer included by Python.h. The remains were
967 moved to longobject.h. It still exists to define several aliases
968 from PyInt_ to PyLong_ functions.
Christian Heimesf78b1c62007-12-02 16:52:32 +0000969
Christian Heimesa37d4c62007-12-04 23:02:19 +0000970- Removed sys.maxint, use sys.maxsize instead.
971
Fred Drake0e474a82007-10-11 18:01:43 +0000972Extension Modules
973-----------------
974
975- The `hotshot` profiler has been removed; use `cProfile` instead.
976
Brett Cannone9fd2312007-10-12 19:18:19 +0000977Library
978-------
979
Georg Brandl52b92cc2008-05-25 09:43:03 +0000980- When loading an external file using testfile(), the passed-in
981 encoding argument was being ignored if __loader__ is defined and
982 forcing the source to be UTF-8.
Brett Cannone9fd2312007-10-12 19:18:19 +0000983
Georg Brandl52b92cc2008-05-25 09:43:03 +0000984- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have
985 been removed in favor of the tempfile module.
Guido van Rossum687b9c02007-10-25 23:18:51 +0000986
Christian Heimesc9543e42007-11-28 08:28:28 +0000987- Removed the 'new' module.
988
Georg Brandl52b92cc2008-05-25 09:43:03 +0000989- Removed all types from the 'types' module that are easily accessable
990 through builtins.
Brett Cannone9fd2312007-10-12 19:18:19 +0000991
Georg Brandl52d168a2008-01-07 18:10:24 +0000992
Guido van Rossum4405cf32007-08-30 17:16:55 +0000993What's New in Python 3.0a1?
Guido van Rossum45aecf42006-03-15 04:58:47 +0000994==========================
Thomas Wouters4d70c3d2006-06-08 14:42:34 +0000995

Neal Norwitz4886cc32006-08-21 17:06:07 +0000997
998Core and Builtins
999-----------------
1000
Martin v. Löwis47383402007-08-15 07:32:56 +00001001- PEP 3131: Support non-ASCII identifiers.
1002
Martin v. Löwis447d33e2007-07-29 18:10:01 +00001003- PEP 3120: Change default encoding to UTF-8.
1004
Martin v. Löwis9f2e3462007-07-21 17:22:18 +00001005- PEP 3123: Use proper C inheritance for PyObject.
1006
Guido van Rossumcd16bf62007-06-13 18:07:49 +00001007- Removed the __oct__ and __hex__ special methods and added a bin()
1008 builtin function.
1009
Georg Brandl52b92cc2008-05-25 09:43:03 +00001010- PEP 3127: octal literals now start with "0o". Old-style octal
1011 literals are invalid. There are binary literals with a prefix of
1012 "0b". This also affects int(x, 0).
Guido van Rossumcd16bf62007-06-13 18:07:49 +00001013
Guido van Rossume7ba4952007-06-06 23:52:48 +00001014- None, True, False are now keywords.
1015
Guido van Rossum29478ef2007-05-29 00:39:44 +00001016- PEP 3119: isinstance() and issubclass() can be overridden.
1017
Guido van Rossumebe3e162007-05-17 18:20:34 +00001018- Remove BaseException.message.
1019
Guido van Rossum1bc535d2007-05-15 18:46:22 +00001020- Remove tuple parameter unpacking (PEP 3113).
1021
Georg Brandl52b92cc2008-05-25 09:43:03 +00001022- Remove the f_restricted attribute from frames. This naturally leads
1023 to the removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
Guido van Rossuma8add0e2007-05-14 22:03:55 +00001024
Georg Brandl52b92cc2008-05-25 09:43:03 +00001025- PEP 3132 was accepted. That means that you can do ``a, *b =
1026 range(5)`` to assign 0 to a and [1, 2, 3, 4] to b.
Guido van Rossum0368b722007-05-11 16:50:42 +00001027
Georg Brandl52b92cc2008-05-25 09:43:03 +00001028- range() now returns an iterator rather than a list. Floats are not
1029 allowed. xrange() is no longer defined.
Guido van Rossum805365e2007-05-07 22:24:25 +00001030
Nick Coghlan650f0d02007-04-15 12:05:43 +00001031- Patch #1660500: hide iteration variable in list comps, add set comps
Georg Brandl52b92cc2008-05-25 09:43:03 +00001032 and use common code to handle compilation of iterative expressions.
Nick Coghlan650f0d02007-04-15 12:05:43 +00001033
Guido van Rossume27dc722007-03-27 22:37:34 +00001034- By default, != returns the opposite of ==, unless the latter returns
1035 NotImplemented.
1036
Georg Brandl52b92cc2008-05-25 09:43:03 +00001037- Patch #1680961: sys.exitfunc has been removed and replaced with a
1038 private C-level API.
Collin Winter670e6922007-03-21 02:57:17 +00001039
Georg Brandl801dd732007-03-18 20:18:31 +00001040- PEP 3115: new metaclasses: the metaclass is now specified as a
Georg Brandl52b92cc2008-05-25 09:43:03 +00001041 keyword arg in the class statement, which can now use the full
1042 syntax of a parameter list. Also, the metaclass can implement a
1043 __prepare__ function which will be called to create the dictionary
1044 for the new class namespace.
Georg Brandl801dd732007-03-18 20:18:31 +00001045
Georg Brandl428f0642007-03-18 18:35:15 +00001046- The long-deprecated argument "pend" of PyFloat_FromString() has been
1047 removed.
1048
Georg Brandle32b4222007-03-10 22:13:27 +00001049- The dir() function has been extended to call the __dir__() method on
Georg Brandl52b92cc2008-05-25 09:43:03 +00001050 its argument, if it exists. If not, it will work like before. This
1051 allows customizing the output of dir() in the presence of a
1052 __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +00001053
Neal Norwitz8dfc4a92007-08-11 06:39:53 +00001054- Removed support for __members__ and __methods__.
1055
Georg Brandle32b4222007-03-10 22:13:27 +00001056- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +00001057
Georg Brandle32b4222007-03-10 22:13:27 +00001058- input() became raw_input(): the name input() now implements the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001059 functionality formerly known as raw_input(); the name raw_input() is
1060 no longer defined.
Guido van Rossum0240b922007-02-26 21:23:50 +00001061
Georg Brandl52b92cc2008-05-25 09:43:03 +00001062- Classes listed in an 'except' clause must inherit from
1063 BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +00001064
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001065- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +00001066 and .keys(), .items(), .values() return dict views, which behave
1067 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +00001068
Guido van Rossum8b545362007-02-09 23:52:14 +00001069- PEP 3105: print is now a function. Also (not in the PEP) the
Georg Brandl52b92cc2008-05-25 09:43:03 +00001070 'softspace' attribute of files is now gone (since print() doesn't
1071 use it). A side effect of this change is that you can get
1072 incomplete output lines in interactive sessions:
Guido van Rossum8b545362007-02-09 23:52:14 +00001073
1074 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +00001075 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +00001076
1077 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +00001078
Brett Cannon398db8b2007-01-29 23:44:37 +00001079- PEP 3102: keyword-only arguments.
1080
Georg Brandl52b92cc2008-05-25 09:43:03 +00001081- Int/Long unification is complete. The 'long' built-in type and
1082 literals with trailing 'L' or 'l' have been removed. Performance
1083 may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +00001084
1085- 'except E, V' must now be spelled as 'except E as V' and deletes V
1086 at the end of the except clause; V must be a simple name.
1087
Neal Norwitzc1505362006-12-28 06:47:50 +00001088- Added function annotations per PEP 3107.
1089
Georg Brandl52b92cc2008-05-25 09:43:03 +00001090- Added nonlocal declaration from PEP 3104:
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +00001091
1092 >>> def f(x):
1093 ... def inc():
1094 ... nonlocal x
1095 ... x += 1
1096 ... return x
1097 ... return inc
1098 ...
1099 >>> inc = f(0)
1100 >>> inc()
1101 1
1102 >>> inc()
1103 2
1104
Georg Brandl66a796e2006-12-19 20:50:34 +00001105- Moved intern() to sys.intern().
1106
1107- exec is now a function.
1108
1109- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +00001110
Neal Norwitz4886cc32006-08-21 17:06:07 +00001111- Classic classes are a thing of the past. All classes are new style.
1112
1113- Exceptions *must* derive from BaseException.
1114
1115- Integer division always returns a float. The -Q option is no more.
1116 All the following are gone:
1117 * PyNumber_Divide and PyNumber_InPlaceDivide
1118 * __div__, __rdiv__, and __idiv__
1119 * nb_divide, nb_inplace_divide
1120 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
1121 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
1122 if we want to re-use __div__ and friends. If we do, it will make
1123 it harder to write code for both 2.x and 3.x.)
1124
1125- 'as' and 'with' are keywords.
1126
1127- Absolute import is the default behavior for 'import foo' etc.
1128
Georg Brandl52b92cc2008-05-25 09:43:03 +00001129- Removed support for syntax: backticks (ie, `x`), <>.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001130
Georg Brandl52b92cc2008-05-25 09:43:03 +00001131- Removed these Python builtins: apply(), callable(), coerce(),
1132 execfile(), file(), reduce(), reload().
Neal Norwitz4886cc32006-08-21 17:06:07 +00001133
Georg Brandl52b92cc2008-05-25 09:43:03 +00001134- Removed these Python methods: {}.has_key.
Neal Norwitz378b2c92006-08-29 07:57:22 +00001135
Georg Brandl52b92cc2008-05-25 09:43:03 +00001136- Removed these opcodes: BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001137
1138- Remove C API support for restricted execution.
1139
Guido van Rossumcf1be882007-08-30 22:07:17 +00001140- zip(), map() and filter() now return iterators, behaving like their
Georg Brandl52b92cc2008-05-25 09:43:03 +00001141 itertools counterparts. This also affect map()'s behavior on
Guido van Rossumcf1be882007-08-30 22:07:17 +00001142 sequences of unequal length -- it now stops after the shortest one
1143 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001144
Georg Brandl52b92cc2008-05-25 09:43:03 +00001145- Additions: set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001146
1147- Added class decorators per PEP 3129.
1148

1150Extension Modules
1151-----------------
1152
Georg Brandl52b92cc2008-05-25 09:43:03 +00001153- Removed the imageop module. Obsolete long with its unit tests
1154 becoming useless from the removal of rgbimg and imgfile.
Neal Norwitz4886cc32006-08-21 17:06:07 +00001155
Georg Brandl52b92cc2008-05-25 09:43:03 +00001156- Removed these attributes from the operator module: div, idiv,
1157 __div__, __idiv__, isCallable, sequenceIncludes.
1158
1159- Removed these attributes from the sys module: exc_clear(), exc_type,
1160 exc_value, exc_traceback.
Guido van Rossumd59da4b2007-05-22 18:11:13 +00001161

1163Library
1164-------
1165
Georg Brandl52b92cc2008-05-25 09:43:03 +00001166- Removed the compiler package. Use of the _ast module and (an
1167 eventual) AST -> bytecode mechanism.
