23Core and Builtins
24-----------------
25
Christian Heimesa156e092008-02-16 07:38:31 +000026- Issue #2115: Important speedup in setting __slot__ attributes. Also
27 prevent a possible crash: an Abstract Base Class would try to access a slot
28 on a registered virtual subclass.
29
30- Fixed repr() and str() of complex numbers with infinity or nan as real or
31 imaginary part.
32
33- Clear all free list during a gc.collect() of the highest generation in order
34 to allow pymalloc to free more arenas. Python may give back memory to the
35 OS earlier.
36
37- Issue #2045: Fix an infinite recursion triggered when printing a subclass of
38 collections.defaultdict, if its default_factory is set to a bound method.
39
40- Fixed a minor memory leak in dictobject.c. The content of the free
41 list was not freed on interpreter shutdown.
42
43- Limit free list of method and builtin function objects to 256 entries
44 each.
45
46- Patch #1953: Added ``sys._compact_freelists()`` and the C API functions
47 ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
48 to compact the internal free lists of pre-allocted ints and floats.
49
50- Bug #1983: Fixed return type of fork(), fork1() and forkpty() calls.
51 Python expected the return type int but the fork familie returns pi_t.
52
53- Issue #1678380: Fix a bug that identifies 0j and -0j when they appear
54 in the same code unit.
55
Raymond Hettinger65baa342008-02-07 00:41:02 +000056- Issue #2025 : Add tuple.count() and tuple.index() methods to comply with
57 the collections.Sequence API.
58
Christian Heimesdfc12ed2008-01-31 15:16:38 +000059- Fixed multiple reinitialization of the Python interpreter. The small int
60 list in longobject.c has caused a seg fault during the third finalization.
61
Christian Heimesc04dac02008-01-30 11:27:57 +000062- Issue #1973: bytes.fromhex('') raises SystemError
63
Raymond Hettinger70b64fc2008-01-30 20:15:17 +000064- Issue #1771: remove cmp parameter from sorted() and list.sort()
65
Christian Heimes7b876152008-01-30 09:51:48 +000066- Issue #1969: split and rsplit in bytearray are inconsistent
67
Raymond Hettinger1dfde1d2008-01-22 23:25:35 +000068- map() and itertools.imap() no longer accept None for the first argument.
69 Use zip() instead.
70
Facundo Batista2336bdd2008-01-19 19:12:01 +000071- Issue #1769: Now int("- 1") is not allowed any more.
72
Christian Heimes386cd1e2008-01-15 02:01:20 +000073- Object/longobject.c: long(float('nan')) raises an OverflowError instead
74 of returning 0.
75
Christian Heimes3b06e532008-01-07 20:12:44 +000076- Issue #1762972: __file__ points to the source file instead of the pyc/pyo
77 file if the py file exists.
78
Guido van Rossumab078dd2008-01-06 00:09:11 +000079- Issue #1393: object_richcompare() returns NotImplemented instead of
80 False if the objects aren't equal, to give the other side a chance.
81
Guido van Rossume239b002008-01-06 00:44:20 +000082- Issue #1692: Interpreter was not displaying location of SyntaxError.
Kurt B. Kaiser43b15092008-01-05 04:32:22 +000083
Amaury Forgeot d'Arcbccd63c2008-01-04 01:21:27 +000084- Improve some exception messages when Windows fails to load an extension
85 module. Now we get for example '%1 is not a valid Win32 application' instead
86 of 'error code 193'. Also use Unicode strings to deal with non-English
87 locales.
88
Christian Heimesa3534a62007-12-11 19:56:40 +000089- Issue #1587: Added instancemethod wrapper for PyCFunctions. The Python C API
90 has gained a new type *PyInstanceMethod_Type* and the functions
91 *PyInstanceMethod_Check(o)*, *PyInstanceMethod_New(func)* and
92 *PyInstanceMethod_Function(im)*.
93
Amaury Forgeot d'Arcad8dcd52007-12-10 23:58:35 +000094- Constants gc.DEBUG_OBJECT and gc.DEBUG_INSTANCE have been removed from the
95 gc module; gc.DEBUG_COLLECTABLE or gc.DEBUG_UNCOLLECTABLE are now enough to
96 print the corresponding list of objects considered by the garbage collector.
97
Guido van Rossume239b002008-01-06 00:44:20 +000098- Issue #1573: Improper use of the keyword-only syntax makes the parser crash.
Christian Heimesbc873412007-12-08 22:11:32 +000099
Christian Heimes0ded5b52007-12-10 15:50:56 +0000100- Issue #1564: The set implementation should special-case PyUnicode instead
Guido van Rossume239b002008-01-06 00:44:20 +0000101 of PyString.
Christian Heimes0ded5b52007-12-10 15:50:56 +0000102
Guido van Rossumea6775b2008-02-21 20:16:31 +0000103- Patch #1031213: Decode source line in SyntaxErrors back to its
104 original source encoding.
Christian Heimes7131fd92008-02-19 14:21:46 +0000105
Christian Heimes09aaa882008-02-23 15:01:06 +0000106- inspect.getsource() includes the decorators again.
107
Guido van Rossumea6775b2008-02-21 20:16:31 +0000108- Bug #1713: posixpath.ismount() claims symlink to a mountpoint is a
109 mountpoint.
Christian Heimes7131fd92008-02-19 14:21:46 +0000110
Christian Heimes7131fd92008-02-19 14:21:46 +0000111- Fix utf-8-sig incremental decoder, which didn't recognise a BOM when the
Guido van Rossumea6775b2008-02-21 20:16:31 +0000112 first chunk fed to the decoder started with a BOM, but was longer than 3
113 bytes.

Christian Heimes043d6f62008-01-07 17:19:16 +0000119- Issue #1762972: Readded the reload() function as imp.reload()
Guido van Rossumea6775b2008-02-21 20:16:31 +0000120
Christian Heimesa156e092008-02-16 07:38:31 +0000121- Bug #2111: mmap segfaults when trying to write a block opened with PROT_READ
122
123- #2063: correct order of utime and stime in os.times() result on Windows.
Christian Heimesbc873412007-12-08 22:11:32 +0000124

127-------
128
Raymond Hettinger48b8b662008-02-05 01:53:00 +0000129- Weakref dictionaries now inherit from MutableMapping.
130 XXX their API still needs to be modernized (i.e. eliminate the iter methods).
131
132- Created new UserDict class in collections module. This one inherits from and
Raymond Hettingerb3a65f82008-02-21 22:11:37 +0000133 complies with the MutableMapping ABC. Also, moved UserString and UserList
134 to the collections module. The MutableUserString class was removed.
Raymond Hettinger48b8b662008-02-05 01:53:00 +0000135
Guido van Rossumea6775b2008-02-21 20:16:31 +0000136- Removed UserDict.DictMixin. Replaced all its uses with
137 collections.MutableMapping.
Raymond Hettingeredf3b732008-02-04 22:07:15 +0000138
Guido van Rossume239b002008-01-06 00:44:20 +0000139- Issue #1703: getpass() should flush after writing prompt.
Christian Heimesfc5aa9d2007-12-11 09:00:01 +0000140
Guido van Rossume239b002008-01-06 00:44:20 +0000141- Issue #1585: IDLE uses non-existent xrange() function.
142
143- Issue #1578: Problems in win_getpass.
144
145
Georg Brandl52d168a2008-01-07 18:10:24 +0000146Build
147-----
148
149- Renamed --enable-unicode configure flag to --with-wide-unicode, since
150 Unicode strings can't be disabled anymore.

Guido van Rossume239b002008-01-06 00:44:20 +0000153C API
154-----
155
156- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
157 Py_TYPE and Py_REFCNT.
158
159- New API PyImport_ImportModuleNoBlock(), works like PyImport_ImportModule()
160 but won't block on the import lock (returning an error instead).

Guido van Rossum40d20bc2007-10-22 00:09:51 +0000170Core and Builtins
171-----------------
172
Brett Cannon37f7e6e2007-10-26 05:42:09 +0000173- str8 now has the same construction signature as bytes.
174
Brett Cannon40430012007-10-22 20:24:51 +0000175- Comparisons between str and str8 now return False/True for ==/!=. sqlite3
176 returns str8 when recreating on object from it's __conform__ value. The
177 struct module returns str8 for all string-related formats. This was true
178 before this change, but becomes more apparent thanks to string comparisons
179 always being False.
180
Guido van Rossum40d20bc2007-10-22 00:09:51 +0000181- Replaced `PyFile_FromFile()` with `PyFile_FromFd(fd, name. mode, buffer,
182 encoding, newline)`
183
184- Fixed `imp.find_module()` to obey the -*- coding: -*- header.
185
186- Changed `__file__` and `co_filename` to unicode. The path names are decoded
187 with `Py_FileSystemDefaultEncoding` and a new API method
188 `PyUnicode_DecodeFSDefault(char*)` was added.
189
Guido van Rossum2dced8b2007-10-30 17:27:30 +0000190- io.open() and _fileio.FileIO have grown a new argument closefd. A false
191 value disables the closing of the file descriptor.
192
Guido van Rossum98297ee2007-11-06 21:34:58 +0000193- Added a new option -b to issues warnings (-bb for errors) about certain
194 operations between bytes/buffer and str like str(b'') and comparsion.
195
Christian Heimes58cb1b82007-11-13 02:19:40 +0000196- The standards streams sys.stdin, stdout and stderr may be None when the
197 when the C runtime library returns an invalid file descriptor for the
198 streams (fileno(stdin) < 0). For now this happens only for Windows GUI
199 apps and scripts started with `pythonw.exe`.
200
Christian Heimesbce52be2007-11-17 19:08:41 +0000201- Added PCbuild9 directory for VS 2008.
202
203- Renamed structmember.h WRITE_RESTRICTED to PY_WRITE_RESTRICTED to work
204 around a name clash with VS 2008 on Windows.
205
Christian Heimesff737952007-11-27 10:40:20 +0000206- Unbound methods are gone for good. ClassObject.method returns an ordinary
207 function object, instance.method still returns a bound method object.
208 The API of bound methods is cleaned up, too. The im_class attribute is
209 removed and im_func + im_self are renamed to __func__ and __self__. The
210 factory PyMethod_New takes only func and instance as argument.
211
Christian Heimesf78b1c62007-12-02 16:52:32 +0000212- intobject.h is no longer included by Python.h. The remains were moved
213 to longobject.h. It still exists to define several aliases from PyInt_
214 to PyLong_ functions.
215
Christian Heimesa37d4c62007-12-04 23:02:19 +0000216- Removed sys.maxint, use sys.maxsize instead.
217
Christian Heimesbce52be2007-11-17 19:08:41 +0000218
Fred Drake0e474a82007-10-11 18:01:43 +0000219Extension Modules

222- The `hotshot` profiler has been removed; use `cProfile` instead.

Brett Cannone9fd2312007-10-12 19:18:19 +0000225Library
226-------
227
228- When loading an external file using testfile(), the passed-in encoding
229 argument was being ignored if __loader__ is defined and forcing the source to
230 be UTF-8.
231
Guido van Rossum687b9c02007-10-25 23:18:51 +0000232- The methods `os.tmpnam()`, `os.tempnam()` and `os.tmpfile()` have been
233 removed in favor of the tempfile module.
234
Christian Heimesc9543e42007-11-28 08:28:28 +0000235- Removed the 'new' module.
236
237- Removed all types from the 'types' module that are easily accessable through
238 builtins.

246Core and Builtins
247-----------------
248
Martin v. Löwis47383402007-08-15 07:32:56 +0000249- PEP 3131: Support non-ASCII identifiers.
250
Martin v. Löwis447d33e2007-07-29 18:10:01 +0000251- PEP 3120: Change default encoding to UTF-8.
252
Martin v. Löwis9f2e3462007-07-21 17:22:18 +0000253- PEP 3123: Use proper C inheritance for PyObject.
254
Guido van Rossumcd16bf62007-06-13 18:07:49 +0000255- Removed the __oct__ and __hex__ special methods and added a bin()
256 builtin function.
257
258- PEP 3127: octal literals now start with "0o". Old-style octal literals
259 are invalid. There are binary literals with a prefix of "0b".
260 This also affects int(x, 0).
261
Guido van Rossume7ba4952007-06-06 23:52:48 +0000262- None, True, False are now keywords.
263
Guido van Rossum29478ef2007-05-29 00:39:44 +0000264- PEP 3119: isinstance() and issubclass() can be overridden.
265
Guido van Rossumebe3e162007-05-17 18:20:34 +0000266- Remove BaseException.message.
267
Guido van Rossum1bc535d2007-05-15 18:46:22 +0000268- Remove tuple parameter unpacking (PEP 3113).
269
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +0000270- Remove the f_restricted attribute from frames. This naturally leads to the
Guido van Rossuma8add0e2007-05-14 22:03:55 +0000271 removal of PyEval_GetRestricted() and PyFrame_IsRestricted().
272
Guido van Rossum0368b722007-05-11 16:50:42 +0000273- PEP 3132 was accepted. That means that you can do ``a, *b = range(5)``
274 to assign 0 to a and [1, 2, 3, 4] to b.
275
Guido van Rossum805365e2007-05-07 22:24:25 +0000276- range() now returns an iterator rather than a list. Floats are not allowed.
277 xrange() is no longer defined.
278
Nick Coghlan650f0d02007-04-15 12:05:43 +0000279- Patch #1660500: hide iteration variable in list comps, add set comps
280 and use common code to handle compilation of iterative expressions
281
Guido van Rossume27dc722007-03-27 22:37:34 +0000282- By default, != returns the opposite of ==, unless the latter returns
283 NotImplemented.
284
Collin Winter670e6922007-03-21 02:57:17 +0000285- Patch #1680961: sys.exitfunc has been removed and replaced with a private
286 C-level API.
287
Georg Brandl801dd732007-03-18 20:18:31 +0000288- PEP 3115: new metaclasses: the metaclass is now specified as a
289 keyword arg in the class statement, which can now use the full syntax of
290 a parameter list. Also, the metaclass can implement a __prepare__ function
291 which will be called to create the dictionary for the new class namespace.
292
Georg Brandl428f0642007-03-18 18:35:15 +0000293- The long-deprecated argument "pend" of PyFloat_FromString() has been
294 removed.
295
Georg Brandle32b4222007-03-10 22:13:27 +0000296- The dir() function has been extended to call the __dir__() method on
297 its argument, if it exists. If not, it will work like before. This allows
298 customizing the output of dir() in the presence of a __getattr__().
Brett Cannonba7bf492007-02-27 00:15:55 +0000299
Neal Norwitz8dfc4a92007-08-11 06:39:53 +0000300- Removed support for __members__ and __methods__.
301
Georg Brandle32b4222007-03-10 22:13:27 +0000302- Removed indexing/slicing on BaseException.
Neal Norwitz2633c692007-02-26 22:22:47 +0000303
Georg Brandle32b4222007-03-10 22:13:27 +0000304- input() became raw_input(): the name input() now implements the
Guido van Rossum0240b922007-02-26 21:23:50 +0000305 functionality formerly known as raw_input(); the name raw_input()
306 is no longer defined.
307
Brett Cannon39590462007-02-26 22:01:14 +0000308- Classes listed in an 'except' clause must inherit from BaseException.
Brett Cannonf74225d2007-02-26 21:10:16 +0000309
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000310- PEP 3106: dict.iterkeys(), .iteritems(), .itervalues() are now gone;
Guido van Rossumcf1be882007-08-30 22:07:17 +0000311 and .keys(), .items(), .values() return dict views, which behave
312 like sets.
Guido van Rossumcc2b0162007-02-11 06:12:03 +0000313
Guido van Rossum8b545362007-02-09 23:52:14 +0000314- PEP 3105: print is now a function. Also (not in the PEP) the
315 'softspace' attribute of files is now gone (since print() doesn't use
316 it). A side effect of this change is that you can get incomplete
317 output lines in interactive sessions:
318
319 >>> print(42, end="")
Kurt B. Kaiser2c7f3142007-08-30 21:52:19 +0000320 42>>>
Guido van Rossum8b545362007-02-09 23:52:14 +0000321
322 We may be able to fix this after the I/O library rewrite.
Guido van Rossum4502c802007-02-09 05:42:38 +0000323
Brett Cannon398db8b2007-01-29 23:44:37 +0000324- PEP 3102: keyword-only arguments.
325
Guido van Rossumd4588c12007-02-13 19:55:23 +0000326- Int/Long unification is complete. The 'long' built-in type
Guido van Rossumec7027f2007-01-30 00:00:40 +0000327 and literals with trailing 'L' or 'l' have been removed.
328 Performance may be sub-optimal (haven't really benchmarked).
Guido van Rossumab186842007-01-14 03:42:30 +0000329
330- 'except E, V' must now be spelled as 'except E as V' and deletes V
331 at the end of the except clause; V must be a simple name.
332
Neal Norwitzc1505362006-12-28 06:47:50 +0000333- Added function annotations per PEP 3107.
334
Jeremy Hyltona4f9fc62007-02-27 15:53:28 +0000335- Added nonlocal declaration from PEP 3104
336
337 >>> def f(x):
338 ... def inc():
339 ... nonlocal x
340 ... x += 1
341 ... return x
342 ... return inc
343 ...
344 >>> inc = f(0)
345 >>> inc()
346 1
347 >>> inc()

349
Georg Brandl66a796e2006-12-19 20:50:34 +0000350- Moved intern() to sys.intern().
351
352- exec is now a function.
353
354- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich4dafcc42006-11-28 19:15:13 +0000355
Neal Norwitz4886cc32006-08-21 17:06:07 +0000356- Classic classes are a thing of the past. All classes are new style.
357
358- Exceptions *must* derive from BaseException.
359
360- Integer division always returns a float. The -Q option is no more.
361 All the following are gone:
362 * PyNumber_Divide and PyNumber_InPlaceDivide
363 * __div__, __rdiv__, and __idiv__
364 * nb_divide, nb_inplace_divide
365 * operator.div, operator.idiv, operator.__div__, operator.__idiv__
366 (Only __truediv__ and __floordiv__ remain, not sure how to handle them
367 if we want to re-use __div__ and friends. If we do, it will make
368 it harder to write code for both 2.x and 3.x.)
369
370- 'as' and 'with' are keywords.
371
372- Absolute import is the default behavior for 'import foo' etc.
373
Neal Norwitz378b2c92006-08-29 07:57:22 +0000374- Removed support for syntax:
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000375 backticks (ie, `x`), <>
Neal Norwitz378b2c92006-08-29 07:57:22 +0000376
Neal Norwitz4886cc32006-08-21 17:06:07 +0000377- Removed these Python builtins:
Neal Norwitz01688022007-08-12 00:43:29 +0000378 apply(), callable(), coerce(), execfile(), file(), reduce(), reload()
Neal Norwitz4886cc32006-08-21 17:06:07 +0000379
Neal Norwitz378b2c92006-08-29 07:57:22 +0000380- Removed these Python methods:
381 {}.has_key
382
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000383- Removed these opcodes:
384 BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT
385
386- Remove C API support for restricted execution.
387
Guido van Rossumcf1be882007-08-30 22:07:17 +0000388- zip(), map() and filter() now return iterators, behaving like their
389 itertools counterparts. This also affect map()'s behavior on
390 sequences of unequal length -- it now stops after the shortest one
391 is exhausted.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000392
393- Additions:
Guido van Rossumcf1be882007-08-30 22:07:17 +0000394 set literals, set comprehensions, ellipsis literal.
Guido van Rossumd59da4b2007-05-22 18:11:13 +0000395
396- Added class decorators per PEP 3129.
