Benjamin Peterson4f51baf2009-12-05 18:40:02 +00007What's New in Python 2.7 alpha 2?
8=================================

11
12Core and Builtins
13-----------------
14
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000015- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
16 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
17
Mark Dickinson1b34d252010-01-01 17:27:30 +000018- Issue #5080: A number of functions and methods previously produced a
19 DeprecationWarning when passed a float argument where an integer was
20 expected. These functions and methods now raise TypeError instead.
21 The majority of the effects of this change are in the extension
22 modules, but some core functions and methods are affected: notably
23 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
24 methods.
25
Benjamin Peterson0f02d392009-12-30 19:34:10 +000026- Issue #7604: Deleting an unset slotted attribute did not raise an
27 AttributeError.
28
Mark Dickinson99d652e2009-12-30 12:12:23 +000029- Issue #7534: Fix handling of IEEE specials (infinities, nans,
30 negative zero) in ** operator. The behaviour now conforms to that
31 described in C99 Annex F.
32
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000033- Issue #7579: the msvcrt module now has docstrings for all its functions.
34
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000035- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
36 used to drop the time part of the result.
37
Mark Dickinson46572832009-12-27 14:55:57 +000038- Issue #1811: improve accuracy and cross-platform consistency for
39 true division of integers: the result of a/b is now correctly
40 rounded for ints a and b (at least on IEEE 754 platforms), and in
41 particular does not depend on the internal representation of a long.
42
Ezio Melottif84caf42009-12-24 22:25:17 +000043- Issue #6108: unicode(exception) and str(exception) should return the same
44 message when only __str__ (and not __unicode__) is overridden in the subclass.
45
Ronald Oussoren92919a62009-12-24 13:30:58 +000046- Issue #6834: replace the implementation for the 'python' and 'pythonw'
47 executables on OSX.
48
49 These executables now work properly with the arch(1) command:
50 ``arch -ppc python`` will start a universal binary version of python
51 in PPC mode (unlike previous releases).
52
R. David Murray0a0a1a82009-12-14 16:28:26 +000053- Issue #1680159: unicode coercion during an 'in' operation no longer masks
54 the underlying error when the coercion fails for the left hand operand.
55
Benjamin Peterson4895af42009-12-13 16:36:53 +000056- Issue #7491: Metaclass's __cmp__ method was ignored.
57
Antoine Pitrou2a08b422009-12-13 16:18:14 +000058- Issue #7466: segmentation fault when the garbage collector is called
59 in the middle of populating a tuple. Patch by Florent Xicluna.
60
R. David Murrayc7298ff2009-12-14 21:57:39 +000061
Benjamin Peterson4f51baf2009-12-05 18:40:02 +000062Library

64
Ezio Melotti569e61f2009-12-30 06:14:51 +000065- Issue #5511: now zipfile.ZipFile can be used as a context manager.
66 Initial patch by Brian Curtin.
67
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +000068- Distutils now correctly identifies the build architecture as "x86_64"
Ezio Melotti569e61f2009-12-30 06:14:51 +000069 when building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +000070
Tarek Ziadé0479eb52009-12-21 23:37:44 +000071- Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest
72 file in text mode.
73
Tarek Ziadé2421d562009-12-20 23:23:34 +000074- Issue #7552: Removed line feed in the base64 Authorization header in
75 the Distutils upload command to avoid an error when PyPI reads it.
76 This occurs on long passwords. Initial patch by JP St. Pierre.
77
78- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +000079 Patch by Tatsuhiro Tsujikawa.
80
Benjamin Petersonddd392c2009-12-13 19:19:07 +000081- Issue #7349: Make methods of file objects in the io module accept None as an
82 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
83 the same as passing no argument.
84
Benjamin Petersonc4771d22009-12-13 17:31:31 +000085- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
86 like other file objects.
87
Lars Gustäbel92ca7562009-12-13 11:32:27 +000088- Issue #7357: tarfile no longer suppresses fatal extraction errors by
89 default.
90

101
Mark Dickinson1b34d252010-01-01 17:27:30 +0000102- Issue #5080: The argument parsing functions PyArg_ParseTuple,
103 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
104 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
105 arguments for integer format codes (other than 'L'): previously an
106 attempt to pass a float resulted in a DeprecationWarning; now it
107 gives a TypeError. For the 'L' format code (which previously had no
108 warning) there is now a DeprecationWarning.
109
Georg Brandl740cdc32009-12-28 08:34:58 +0000110- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

Benjamin Peterson6c99b4e2010-01-01 15:20:06 +0000118 --with-system-ffi flag is used.
Benjamin Petersonb4abef62010-01-01 15:18:38 +0000119
Benjamin Peterson2c196742009-12-31 03:17:18 +0000120- Issue #7609: Add a --with-system-expat option that causes the system's expat
121 library to be used for the pyexpat module instead of the one included with
122 Python.
123
Benjamin Peterson500ce232009-12-30 02:58:50 +0000124- Issue #7589: Only build the nis module when the correct header files are

134
R. David Murray77e48ba2009-12-20 16:46:06 +0000135- Issue #7376: instead of running a self-test (which was failing) when called
136 with no arguments, doctest.py now gives a usage message.
137
R. David Murray98e3df32009-12-16 11:49:46 +0000138- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
139
R. David Murrayc7298ff2009-12-14 21:57:39 +0000140- Issue #7498: test_multiprocessing now uses test_support.find_unused_port

150Core and Builtins
151-----------------
152
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000153- Issue #7419: setlocale() could crash the interpreter on Windows when called
154 with invalid values.
155
Eric Smithc4ab8332009-11-29 17:40:57 +0000156- Issue #3382: 'F' formatting for float and complex now convert the
157 result to upper case. This only affects 'inf' and 'nan', since 'f'
158 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000159
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000160- Remove switch from "%f" formatting to "%g" formatting for floats
161 larger than 1e50 in absolute value.
162
Mark Dickinson18cfada2009-11-23 18:46:41 +0000163- Remove restrictions on precision when formatting floats. E.g.,
164 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
165 requested 120 significant digits instead.
166
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000167- Add Py3k warnings for parameter names in parenthesis.
168
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000169- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000170
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000171- Issue #7085: Fix crash when importing some extensions in a thread
172 on MacOSX 10.6.
173
Mark Dickinsonb678de82009-11-19 18:41:49 +0000174- Issue #7117: repr(x) for a float x returns a result based on the
175 shortest decimal string that's guaranteed to round back to x under
176 correct rounding (with round-half-to-even rounding mode).
177 Previously it gave a string based on rounding x to 17 decimal digits.
178 repr(x) for a complex number behaves similarly. On platforms where
179 the correctly-rounded strtod and dtoa code is not supported (see below),
180 repr is unchanged.
181
182- Issue #7117: On almost all platforms: float-to-string and
183 string-to-float conversions within Python are now correctly rounded.
184 Places these conversions occur include: str for floats and complex
185 numbers; the float and complex constructors; old-style and new-style
186 numeric formatting; serialization and deserialization of floats and
187 complex numbers using marshal, pickle and json; parsing of float and
188 imaginary literals in Python code; Decimal-to-float conversion.
189
190 The conversions use a Python-adapted version of David Gay's
191 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
192 functions. This code is supported on Windows, and on Unix-like
193 platforms using gcc, icc or suncc as the C compiler. There may be a
194 small number of platforms on which correct operation of this code
195 cannot be guaranteed, so the code is not used: notably, this applies
196 to platforms where the C double format is not IEEE 754 binary64, and
197 to platforms on x86 hardware where the x87 FPU is set to 64-bit
198 precision and Python's configure script is unable to determine how
199 to change the FPU precision. On these platforms conversions use the
200 platform strtod and dtoa, as before.
201
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000202- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000203 now uses the correctly-rounded string <-> float conversions
204 described above (when available), and so produces correctly rounded
205 results that will display nicely under the float repr. There are
206 two related small changes: (1) round now accepts any class with an
207 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000208 floats for the second argument), and (2) an excessively large second
209 integer argument (e.g., round(1.234, 10**100)) no longer raises an
210 exception.
211
Philip Jenveyfab8be22009-11-17 02:42:26 +0000212- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
213
Benjamin Petersone36199b2009-11-12 23:39:44 +0000214- Fix several issues with compile(). The input can now contain Windows and Mac
215 newlines and is no longer required to end in a newline.
216
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000217- Remove length limitation when constructing a complex number from a
218 unicode string.
219
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000220- Issue #7244: itertools.izip_longest() no longer ignores exceptions
221 raised during the formation of an output tuple.
222
Mark Dickinson8d87dc02009-10-25 20:39:06 +0000223- Issue #1087418: Boost performance of bitwise operations for longs.
224
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000225- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
226 fixes the problem of some exceptions being thrown at shutdown when the
227 interpreter is killed. Patch by Adam Olsen.
228
Eric Smithc12781a2009-10-19 14:38:14 +0000229- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and
230 note that they are unsafe and deprecated.
231
Vinay Sajip03d5c342009-10-16 14:06:44 +0000232- Issue #7120: logging: Removed import of multiprocessing which is causing
233 crash in GAE.
234
Benjamin Peterson196b0922009-10-15 15:44:46 +0000235- Issue #7140: The __dict__ of a module should not be cleared unless the module
236 is the only object holding a reference to it.
237
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000238- Issue #1754094: Improve the stack depth calculation in the compiler.
239 There should be no other effect than a small decrease in memory use.
240 Patch by Christopher Tur Lesniewski-Laas.
241
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000242- Issue #7084: Fix a (very unlikely) crash when printing a list from one
243 thread, and mutating it from another one. Patch by Scott Dial.
244
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000245- Issue #1571184: The Unicode database contains properties for more characters.

315
Raymond Hettinger62641e92009-06-23 20:59:43 +0000316- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
317 because it wasn't recognized as a sequence).
318
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +0000319- Issue #6289: Encoding errors from compile() were being masked.
320
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000321- When no module is given in a relative import, the module field of the
322 ImportFrom AST node is now None instead of an empty string.
323
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000324- Assignment to None using import statements now raises a SyntaxError.
325
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +0000326- Issue #4547: When debugging a very large function, it was not always
327 possible to update the lineno attribute of the current frame.
328
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000329- Issue #5330: C functions called with keyword arguments were not reported by
Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000330 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000331
Raymond Hettinger578a2282009-05-29 04:58:52 +0000332- Issue #5982: staticmethod and classmethod now expose the wrapped
333 function with __func__.
334
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000335- Added support for multiple context managers in the same with-statement.
336 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +0000337
Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000338- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
339 statement and correctly lookup the __enter__ and __exit__ special methods.
340
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000341- Issue #5829: complex("1e500") no longer raises OverflowError. This
342 makes it consistent with float("1e500") and interpretation of real
343 and imaginary literals.
344
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000345- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
346
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000347- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
348 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000349
R. David Murray525cffc2009-05-13 13:07:14 +0000350- Issue #5994: the marshal module now has docstrings.
351
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000352- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
353 (1) inf and nan strings with trailing whitespace were incorrectly
354 rejected; (2) parsing of strings representing infinities and nans
355 was locale aware; and (3) the interpretation of fromhex('-nan')
356 didn't match that of float('-nan').
357
Eric Smitha985a3a2009-05-05 18:26:08 +0000358- Issue #5920: For float.__format__, change the behavior with the
359 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
360 to be like 'g' but with at least one decimal point and with a
361 default precision of 12. Previously, the behavior the same but with
362 a default precision of 6. This more closely matches str(), and
363 reduces surprises when adding alignment flags to the empty
364 presentation type. This also affects the new complex.__format__ in
365 the same way.
366
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000367- Issue #5890: in subclasses of 'property' the __doc__ attribute was
368 shadowed by classtype's, even if it was None. property now
369 inserts the __doc__ into the subclass instance __dict__.
370
Antoine Pitrou653dece2009-05-04 18:32:32 +0000371- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
372 sequences. Patch by Nick Barnes and Victor Stinner.
373
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000374- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000375 format(complex(1, 2./3), '.5') now produces a sensible result.
376
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000377- Issue #5864: Fix empty format code formatting for floats so that it
378 never gives more than the requested number of significant digits.
379
Eric Smithcac7af62009-04-27 19:04:37 +0000380- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
381 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.

384 titlecase, but not their own uppercase.
385
Eric Smith068f0652009-04-25 21:40:15 +0000386- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
387 _PyOS_double_to_string or PyOS_double_to_string.
388
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000389- Issue #5283: Setting __class__ in __del__ caused a segfault.
390
Mark Dickinson95bc9802009-04-24 12:46:53 +0000391- Issue #5816: complex(repr(z)) now recovers z exactly, even when
392 z involves nans, infs or negative zeros.
393
Eric Smithaca19e62009-04-22 13:29:05 +0000394- Implement PEP 378, Format Specifier for Thousands Separator, for
395 floats, ints, and longs.
396
397- Issue #5515: 'n' formatting for ints, longs, and floats handles
398 leading zero formatting poorly.
399
400- Issue #5772: For float.__format__, don't add a trailing ".0" if
401 we're using no type code and we have an exponent.
402
Mark Dickinson6736cf82009-04-20 21:13:33 +0000403- Issue #3166: Make long -> float (and int -> float) conversions
404 correctly rounded.
405
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000406- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
407 some builtin types.
408
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000409- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000410 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000411
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000412- Issue #5759: float() didn't call __float__ on str subclasses.
413
Georg Brandl3c4a5462009-04-12 12:08:12 +0000414- Issue #5704: the "-3" command-line option now implies "-t".
415
R. David Murray0374a822009-04-09 21:54:50 +0000416- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
417 its clarity and its speed.
418
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000419- Issue #2396: the memoryview object was backported from Python 3.1.
420

425
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000426- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
427 the end sys.path, for compatibility with the system install of Python.
428
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000429- Issue #4688: Add a heuristic so that tuples and dicts containing only
430 untrackable objects are not tracked by the garbage collector. This can
431 reduce the size of collections and therefore the garbage collection overhead
432 on long-running programs, depending on their particular use of datatypes.
433
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000434- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
435 improve its performance. Long divisions and remainder operations
436 are now between 50% and 150% faster.
437
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000438- Issue #4258: Make it possible to use base 2**30 instead of base
439 2**15 for the internal representation of integers, for performance
440 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
441 --enable-big-digits option to configure, which overrides the
442 default. Add sys.long_info structseq to provide information about
443 the internal format.
444
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000445- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
446 result traceback.__members__ no longer exists.)
447
Mark Dickinson6b265f12009-03-18 16:07:26 +0000448- Issue #4474: PyUnicode_FromWideChar now converts characters outside
449 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
450 and sizeof(Py_UNICODE) == 2.
451
Eric Smith6f42edb2009-03-14 11:57:26 +0000452- Issue #5237: Allow auto-numbered fields in str.format(). For
453 example: '{} {}'.format(1, 2) == '1 2'.
454
Brett Cannon6c4cff02009-03-11 04:51:06 +0000455- Issue #3652: Make the 'line' argument for warnings.showwarning() a
456 requirement. Means the DeprecationWarning from Python 2.6 can go away.
457
Eric Smithe9fb6862009-02-20 14:02:36 +0000458- Issue #5247: Improve error message when unknown format codes are
459 used when using str.format() with str, unicode, long, int, and
460 float arguments.
461
Raymond Hettinger08259e82009-02-18 23:10:19 +0000462- Running Python with the -3 option now also warns about classic division
463 for ints and longs.
464
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000465- Issue #5260: Long integers now consume less memory: average
466 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
467 on a 64-bit system.
468
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000469- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
470 rotating the object pointer by 4 bits to the right.
471
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000472- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
473 it now forces its argument to double before testing for infinity.
474
Benjamin Petersone18ef192009-01-20 14:21:16 +0000475- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
476
Georg Brandl29c6a282009-04-05 20:23:13 +0000477- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000478 were suppressing all exceptions. These include list(), filter(), map(),
479 zip(), and bytearray().
480
Benjamin Peterson596d3062009-01-19 15:42:23 +0000481- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
482 functions.
483
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000484- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
485 OSError.

488
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000489- Issue #4935: The overflow checking code in the expandtabs() method common
490 to str, bytes and bytearray could be optimized away by the compiler, letting
491 the interpreter segfault instead of raising an error.
492
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000493- Issue #3720: Fix a crash when an iterator modifies its class and removes its
494 __next__ method.
495

499
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000500- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
501 collecting the oldest generation) so that allocating lots of objects without
502 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000503 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000504 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

507
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000508- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
509 an existing .py counterpart, override the co_filename attributes of all
510 code objects if the original filename is obsolete (which can happen if the
511 file has been renamed, moved, or if it is accessed through different paths).
512 Patch by Ziga Seilnacht and Jean-Paul Calderone.
513
Martin v. Löwis5344c992009-01-02 20:32:55 +0000514- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000516- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
517 file with `str' filename on Windows.
518
Antoine Pitrouaa687902009-01-01 14:11:22 +0000519- Issue #3680: Reference cycles created through a dict, set or deque iterator
520 did not get collected.
521
Nick Coghlan180e4002008-12-30 01:18:48 +0000522- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
523 where the tp_hash and tp_dict slots are both NULL.
524
Benjamin Peterson7af65562008-12-29 17:56:58 +0000525- Issue #4764: With io.open, IOError.filename is set when trying to open a
526 directory on POSIX systems.
527
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000528- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

533
Skip Montanarof205c132008-12-23 03:30:15 +0000534- Added test case to ensure attempts to read from a file opened for writing
535 fail.
536
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000537- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
538 print elapsed times, not only when some objects are uncollectable /
539 unreachable. Original patch by Neil Schemenauer.
540
Mark Dickinson1a707982008-12-17 16:14:37 +0000541- Issue #3439: Add a bit_length method to int and long.

Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000546- Issue #4597: Fixed exception handling when the __exit__ function of a
547 context manager returns a value that cannot be converted to a bool.
548
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000549- Issue #4597: Fixed several opcodes that weren't always propagating
550 exceptions.
551
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000552- Issue #4445: Replace "sizeof(PyStringObject)" with
553 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
554 str instances. On a typical machine this saves 3 bytes of memory
555 (on average) per string allocation.
556
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000557- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
558 interpreter to abort ("Fatal Python error: Could not reset the stack!")
559 instead of throwing a MemoryError.
560
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000561- Issue #3689: The list reversed iterator now supports __length_hint__
562 instead of __len__. Behavior now matches other reversed iterators.
563
Benjamin Petersonc078f922008-11-21 22:27:24 +0000564- Issue #4367: Python would segfault during compiling when the unicodedata
565 module couldn't be imported and \N escapes were present.
566
Vinay Sajip213faca2008-12-03 23:22:58 +0000567- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000568 method on file objects with closefd=False. The file descriptor is still
569 kept open but the file object behaves like a closed file. The ``FileIO``
570 object also got a new readonly attribute ``closefd``.
571
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000572- Issue #4348: Some bytearray methods returned that didn't cause any change to
573 the bytearray, returned the same bytearray instead of a copy.
574
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000575- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
576

578
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000579- Issue #4048: The parser module now correctly validates relative imports.
580
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000581- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
582 exec statement.
583
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000584- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
585 method does not return iterators for the 4th and 5th items.
586
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000587- Issue #4209: Enabling unicode_literals and the print_function in the same
588 __future__ import didn't work.
589
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000590- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000591 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000592
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000593- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
594 returned a path longer than MAX_PATH. (But It's doubtful this code path is
595 really executed because I cannot move to such directory on win2k)
596
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000597- Issue #4069: When set.remove(element) is used with a set element, the element
598 is temporarily replaced with an equivalent frozenset. But the eventual
599 KeyError would always report the empty frozenset([]) as the missing key. Now
600 it correctly refers to the initial element.
601
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000602- Issue #4509: Various issues surrounding resize of bytearray objects to

623 of using the replace error handler in PyUnicode_DecodeUTF8().
624

1170 allows for much simpler resource allocation and deallocation during tests.
1171

1183
Michael Foord345b2fe2009-04-02 03:20:38 +00001184- Issue #5663: better failure messages for unittest asserts. Default assertTrue
1185 and assertFalse messages are now useful. TestCase has a longMessage attribute.
1186 This defaults to False, but if set to True useful error messages are shown in
1187 addition to explicit messages passed to assert methods.

1868 leak-chasing test runs give sensible results. The previous method of
1869 reaping threads could return successfully while some Thread objects were

2009-----------------
2010
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002011- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2012
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002013- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2014 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2015 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2016 ``printf`` function, whereas PyString_FromFormat has an independent
2017 implementation and uses "%zd" on all platforms for size_t values.
2018 This makes a difference on win64, where ``printf`` needs "%Id" to display
2019 64bit values.
2020
Benjamin Peterson97179b02008-09-09 20:55:01 +00002021- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2022 error.
2023
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002024- Issue #3777: long() applied to a float object now always return a long
2025 object; previously an int would be returned for small values. the __long__
2026 method is allowed to return either an int or a long, but the behaviour of
2027 float objects should not change to respect backward compatibility.
2028
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002029- Issue #3751: str.rpartition would perform a left-partition when called with
2030 a unicode argument.
2031
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002032- Issue #3683: Fix compilation when --without-threads is given.
2033
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002034- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002035 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002036 was correctly parsed but parsing of subsequent arguments failed.
2037
Vinay Sajip35e3b032008-09-01 14:33:59 +00002038- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002039 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2040 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2041 when given a tuple of classes as second argument, were looking up
2042 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2043 type object.
2044
Neal Norwitz18aa3882008-08-24 05:04:52 +00002045- Fix crashes on memory allocation failure found with failmalloc.
2046
2047- Fix memory leaks found with valgrind and update suppressions file.
2048
2049- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2050
2051- Fix problem using wrong name in decimal module reported by pychecker.
2052
Christian Heimes7d4c3172008-08-22 19:47:25 +00002053- Silenced another compiler warning about a used but not defined
2054 function 'stringlib_contains_obj'.
2055

2057 ``__delslice__``.
2058
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002059- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2060 library targets in the Makefile.
2061
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002062- Issue #1204: The configure script now tests for additional libraries
2063 that may be required when linking against readline. This fixes issues
2064 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00002087- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002088 return a list or None rather than a custom object.

2114 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2115 for catch_warnings() also led to an improvement in the raising of a
2116 DeprecationWarning related to warnings.warn_explicit().
2117

2183================================
2184
Barry Warsaw07a4a382008-08-21 01:15:08 +00002185*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002186
2187Core and Builtins
2188-----------------
2189
Guido van Rossumf8402962008-08-20 15:01:50 +00002190- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2191 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2192 extensions do not automatically benefit from the class attribute
2193 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2194 to their tp_flags field if they care. This is a backwards
2195 compatibility feature; in 3.0, all types will use the cache by
2196 default.
2197
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002198- Keyword arguments can now follow starred arguments. (``f(a, *args,
2199 keyword=23)`` is now valid syntax.)
2200
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002201- ctypes function pointers that are COM methods have a boolean True
2202 value again.
2203
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002204- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2205 by denying s# to parse objects that have a releasebuffer procedure,
2206 and introducing s*.
2207
Georg Brandl1e13ea92008-08-11 09:07:59 +00002208- Issue #3537: Fix an assertion failure when an empty but presized dict
2209 object was stored in the freelist.
2210
Mark Dickinsonb6467572008-08-04 21:30:09 +00002211- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2212 ValueError consistently across platforms.
2213
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002214- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2215 (64bit Unix, for example), unichr() would truncate its argument and return
2216 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2217
Neal Norwitze7d8be82008-07-31 17:17:14 +00002218- Apply security patches from Apple.
2219
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002220- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2221 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2222
Antoine Pitrou92f82162008-07-25 22:22:08 +00002223- Issue #1819: function calls with several named parameters are now on
2224 average 35% faster (as measured by pybench).
2225
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002226- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2227 the python debugger steps into a class statement: the free variables (local
2228 variables defined in an outer scope) would be deleted from the outer scope.
2229
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002230- Issue #2620: Overflow checking when allocating or reallocating memory
2231 was not always being done properly in some python types and extension
2232 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2233 all been updated to perform better checks and places in the code that
2234 would previously leak memory on the error path when such an allocation
2235 failed have been fixed.

2243 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2244
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002245- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2246 version reported by these tools does not necessarily follow the python
2247 version numbering scheme, so the module is less strict when parsing it.
2248
Nick Coghlanf70385a2008-08-18 12:42:46 +00002249- Issue #2235: Added Py3k warnings for types which will become unhashable
2250 under the stricter __hash__ inheritance rules in 3.0. Several types
2251 which did not meet the rules for hash invariants and were already
2252 unhashable in 3.0 have now been explicitly flagged as unhashable in
2253 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2254 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2255
Brett Cannon88f801d2008-08-18 00:46:22 +00002256- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2257 imported into the module but exposed as part of the module's API.
2258
Brett Cannon7b96f072008-08-18 00:41:11 +00002259- Remove an unneeded import of abc.ABCMeta from 'inspect'.

2264
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002265- Issue #3575: Incremental decoder's decode function now takes bytearray
2266 by using 's*' instead of 't#'.
2267
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002268- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002269 fails unicode conversion on 2nd parameter. (windows only)

Facundo Batista94f243a2008-08-17 03:38:39 +00002271- Issue 2464. urllib2 now supports a malformation in the URL received
2272 in a redirect.

2303 to _sre.compile() will now be rejected. This should not affect anybody
2304 since the re.compile() function never generates invalid re-bytecode.

2308 it wasn't initialized during instantiation.
2309
Brett Cannon3aa2a492008-08-06 22:28:09 +00002310- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2311 the reload() built-in has been removed.

2322 raised an AttributeError.
2323
Benjamin Peterson01a24322008-07-28 23:35:27 +00002324- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002325 asking for a specific length. This problem only affected files opened
2326 using the new "io" module, not the built-in open() function.

2353 mode 0600 rather than 000 under Unix.
2354
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002355- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2369
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002370- Issue #643841: The language reference now provides more detailed

2382-----------------
2383
Georg Brandl3e483f62008-07-16 22:57:41 +00002384- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2385 its methods now allow for items objects that can be converted to
2386 an integer using operator.index().
2387
Mark Dickinson64b7e502008-07-16 09:40:03 +00002388- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2389 produced a ValueError instead of giving the correct float.
2390
Eric Smitha5fa5a22008-07-16 00:11:49 +00002391- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2392 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2393
Mark Dickinson7103aa42008-07-15 19:08:33 +00002394- Issue #3008: the float type has a new instance method 'float.hex'
2395 and a new class method 'float.fromhex' to convert floating-point
2396 numbers to and from hexadecimal strings, respectively.
2397
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002398- Issue #2235: __hash__ is once again inherited by default. To allow
2399 collections.Hashable to remain meaningful in the presence of the
2400 default hash implementation (object.__hash__), it is now possible
2401 to explicit block inheritance of hash by setting __hash__=None at
2402 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2403 level.
2404
Nick Coghlanb028f502008-07-13 14:52:36 +00002405- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2406 the parent module cannot be found while performing an absolute import.
2407 This means that an incorrectly defined __package__ attribute will
2408 now only prevent relative imports in that module rather than causing
2409 all imports from that module to fail.
2410
Nick Coghlan14ff9942008-07-08 14:21:42 +00002411- Issue #2517: Allow unicode messages in Exceptions again by correctly

2421 another thread's dictionary.
2422
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002423- Issue #3004: Minor change to slice.indices(): the start and stop
2424 arguments are now treated identically, making the behaviour easier
2425 to describe and understand. For example, slice(None, -10,
2426 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2427 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2428 10, -1).
2429
Georg Brandl278fc502008-07-19 12:46:12 +00002430- Issue #3219: Calling a function with repeated keyword arguments,
2431 f(a=2, a=23), would not cause a syntax error. This was a regression
2432 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002433
Georg Brandl278fc502008-07-19 12:46:12 +00002434- Issue #2862: Make int and float freelist management consistent with
2435 other freelists. Changes their CompactFreeList apis into

2442 api functions without holding the GIL, which could lead to a fatal
2443 error when they failed.
2444
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002445- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002470- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2471 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002472 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002473 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002489- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2879
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002880- On MacOS X it is now possible to install the framework in 64-bit
2881 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002882 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002883
2884 This is controlled by the configure argument ``--with-universal-archs``:
2885
2886 - ``--with-universal-archs=all``: install 4-way universal
2887
2888 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2889
2890 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2891
2892 This option should be used in combination with ``--enable-universalsdk=``.
2893
2894 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002944- Issue #1631171: Re-implement the 'warnings' module in C (the
2945 original Python code has been kept as backup). This will allow for
2946 using the 'warning's machinery in such places as the parser where
2947 use of pure Python code is not possible. Both the ``showarning()``
2948 and ``formatwarning()`` gain an optional 'line' argument which is
2949 not called by default for backwards-compatibility reasons. Setting
2950 ``warnings.showwarning()`` to an implementation that lacks support
2951 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002976- The getpass module has been improved on Unix. It now uses /dev/tty
2977 by default and uses stderr instead of stdout. A GetPassWarning is
2978 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002993- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002994 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003014- Issue #2550: The approach used by client/server code for obtaining
3015 ports to listen on in network-oriented tests has been refined in an
3016 effort to facilitate running multiple instances of the entire
3017 regression test suite in parallel without issue.
3018 test_support.bind_port() has been fixed such that it will always
3019 return a unique port -- which wasn't always the case with the
3020 previous implementation, especially if socket options had been set
3021 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3022 new implementation of bind_port() will actually raise an exception
3023 if it is passed an AF_INET/SOCK_STREAM socket with either the
3024 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3025 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3026 the socket it's been passed. This currently only applies to
3027 Windows. This option prevents any other sockets from binding to the
3028 host/port we've bound to, thus removing the possibility of the
3029 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3030 when a second SOCK_STREAM socket binds and accepts to a host/port
3031 that's already been bound by another socket. The optional preferred
3032 port parameter to bind_port() has been removed. Under no
3033 circumstances should tests be hard coding ports!
3034
3035 test_support.find_unused_port() has also been introduced, which will
3036 pass a temporary socket object to bind_port() in order to obtain an
3037 unused port. The temporary socket object is then closed and
3038 deleted, and the port is returned. This method should only be used
3039 for obtaining an unused port in order to pass to an external program
3040 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3041 a parameter to a server-oriented class that doesn't give you direct
3042 access to the underlying socket used.
3043
3044 Finally, test_support.HOST has been introduced, which should be used
3045 for the host argument of any relevant socket calls (i.e. bind and
3046 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003047
3048 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003050 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3051 test_asynchat and test_socket_ssl.
3052
Georg Brandl3ee81df2008-05-17 18:14:43 +00003053 It is now possible for multiple instances of the regression test
3054 suite to run in parallel without issue.

3321-----------------
3322
Fred Drakea8ee94b2008-03-01 02:45:07 +00003323- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003324 644. The mode is now inherited from the py file.

3327
3328- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003329
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003330- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003331 issue 215555 for a discussion.
3332
Eric Smitha73fbe72008-02-23 03:09:44 +00003333- Added the future_builtins module, which contains hex() and oct().
3334 These are the PEP 3127 version of these functions, designed to be
3335 compatible with the hex() and oct() builtins from Python 3.0. They
3336 differ slightly in their output formats from the existing, unchanged
3337 Python 2.6 builtins. The expected usage of the future_builtins
3338 module is:
3339 from future_builtins import hex, oct
3340
Eric Smith7ef40bf2008-02-20 23:34:22 +00003341- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3342 exponents for exponents with absolute value < 100. Follows C99
3343 standard. This is a change on Windows, which would use 3 digits.
3344 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3345 so that any alterations it does to the resulting string will be
3346 available in stringlib/formatter.h (for float.__format__).
3347
Eric Smith5a3c1352008-02-19 13:21:56 +00003348- Implemented PEP 3101, Advanced String Formatting. This adds a new
3349 builtin format(); a format() method for str and unicode; a
3350 __format__() method to object, str, unicode, int, long, float, and
3351 datetime; the class string.Formatter; and the C API
3352 PyObject_Format().
3353
Georg Brandl3ee81df2008-05-17 18:14:43 +00003354- Fixed several potential crashes, all caused by specially crafted
3355 __del__ methods exploiting objects in temporarily inconsistent
3356 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003357
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003358- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003359 prevent a possible crash: an Abstract Base Class would try to access
3360 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003361

3363 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003364
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- Clear all free lists during a gc.collect() of the highest generation
3366 in order to allow pymalloc to free more arenas. Python may give back

Georg Brandl3ee81df2008-05-17 18:14:43 +00003369- Issue #2045: Fix an infinite recursion triggered when printing a
3370 subclass of collections.defaultdict, if its default_factory is set
3371 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003372
Christian Heimesf75dbef2008-02-08 00:11:31 +00003373- Fixed a minor memory leak in dictobject.c. The content of the free
3374 list was not freed on interpreter shutdown.
3375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- Limit free list of method and builtin function objects to 256
3377 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003378
Georg Brandl3ee81df2008-05-17 18:14:43 +00003379- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3380 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003381 to compact the internal free lists of pre-allocted ints and floats.
3382
Georg Brandl3ee81df2008-05-17 18:14:43 +00003383- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3384 calls. Python expected the return type int but the fork familie
3385 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3388 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003389
Georg Brandl3ee81df2008-05-17 18:14:43 +00003390- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3391 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003392
Georg Brandl3ee81df2008-05-17 18:14:43 +00003393- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003396- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3397 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003398
Georg Brandl3ee81df2008-05-17 18:14:43 +00003399- Patch #1473257: generator objects gain a gi_code attribute. This is
3400 the same object as the func_code attribute of the function that
3401 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003402
Georg Brandl3ee81df2008-05-17 18:14:43 +00003403- Issue #1920: "while 0" statements were completely removed by the
3404 compiler, even in the presence of an "else" clause, which is
3405 supposed to be run when the condition is false. Now the compiler
3406 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003407
Guido van Rossumeead05f2008-01-24 18:21:02 +00003408- A few crashers fixed: weakref_in_del.py (issue #1377858);
3409 loosing_dict_ref.py (issue #1303614, test67.py);
3410 borrowed_ref_[34].py (not in tracker).
3411
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003412- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003413 suppressed while an extension is loaded by calling SetErrorMode in
3414 dynload_win.c. The error is still reported properly.
3415
Georg Brandl3ee81df2008-05-17 18:14:43 +00003416- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003417 several extension methods and modules do not work without unicode
3418 support.
3419
Georg Brandl26543b12008-01-21 18:36:51 +00003420- Issue #1882: when compiling code from a string, encoding cookies in the
3421 second line of code were not always recognized correctly.
3422
Georg Brandl14404b62008-01-19 19:27:05 +00003423- Issue #1679: "0x" was taken as a valid integer literal.
3424
Georg Brandl6caad7d2008-01-26 14:19:22 +00003425- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003426 added.
3427
Christian Heimesc94e2b52008-01-14 04:13:37 +00003428- sys.float_info / PyFloat_GetInfo: The floating point information
3429 object was converted from a dict to a specialized structseq object.
3430
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431- Patch #1816: Added sys.flags structseq. It exposes the status of
3432 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003433
Georg Brandl3ee81df2008-05-17 18:14:43 +00003434- Objects/structseq.c: Implemented new structseq representation. The
3435 patch makes structseqs (e.g. the return value of os.stat) more
3436 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003437
Georg Brandl3ee81df2008-05-17 18:14:43 +00003438- Patch #1700288: added a type attribute cache that caches method
3439 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003440
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003441- Bug #1776: __import__() no longer accepts filenames on any platform.
3442 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003443

3445
Georg Brandl3ee81df2008-05-17 18:14:43 +00003446- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3447 envvar and sys.dont_write_bytecode attribute. All these can be set
3448 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003449
Georg Brandl3ee81df2008-05-17 18:14:43 +00003450- Improve some exception messages when Windows fails to load an
3451 extension module. Now we get for example '%1 is not a valid Win32
3452 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003453

Christian Heimes0a8143f2007-12-18 23:22:54 +00003459- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003460 and INF. float("nan"), float("inf") and float("-inf") now work on
3461 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003462
Georg Brandl3ee81df2008-05-17 18:14:43 +00003463- Compiler now generates simpler and faster code for dictionary
3464 literals. The oparg for BUILD_MAP now indicates an estimated
3465 dictionary size. There is a new opcode, STORE_MAP, for adding
3466 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003495- Patch #1739468: Directories and zipfiles containing a __main__.py
3496 file can now be directly executed by passing their name to the
3497 interpreter. The directory/zipfile is automatically inserted as the
3498 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003500- Issue #1265: Fix a problem with sys.settrace, if the tracing
3501 function uses a generator expression when at the same time the
3502 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003503
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003504- sets and frozensets now have an isdisjoint() method.
3505

3507
Neal Norwitz44f326e2007-10-05 05:29:17 +00003508- Fix warnings found by the new version of the Coverity checker.
3509
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- The enumerate() builtin function is no longer bounded to sequences
3511 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3512 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003513
Georg Brandl3ee81df2008-05-17 18:14:43 +00003514- Issue #1686386: Tuple's tp_repr did not take into account the
3515 possibility of having a self-referential tuple, which is possible
3516 from C code. Nor did object's tp_str consider that a type's tp_str
3517 could do something that could lead to an inifinite recursion.
3518 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3519 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003520
Georg Brandl3ee81df2008-05-17 18:14:43 +00003521- Issue #1164: It was possible to trigger deadlock when using the
3522 'print' statement to write to a file since the GIL was not released
3523 as needed. Now PyObject_Print() does the right thing along with
3524 various tp_print implementations of the built-in types and those in
3525 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003526
Georg Brandl3ee81df2008-05-17 18:14:43 +00003527- Issue #1147: Exceptions were directly allowing string exceptions in
3528 their throw() method even though string exceptions no longer
3529 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003530
Georg Brandl3ee81df2008-05-17 18:14:43 +00003531- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00003533
Brett Cannon1e534b52007-09-07 04:18:30 +00003534- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535 PyObject_Call() never calling back out to Python code to trigger
3536 recursion depth updates/checks. Required the creation of a static
3537 RuntimeError instance in case normalizing an exception put the
3538 recursion check value past its limit. Fixes crashers
3539 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003540

Neal Norwitz0ac60192007-05-27 04:08:54 +00003554- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003555 __*__ attributes. (Some already existed, e.g., __doc__ and
3556 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003557
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003558- Add -3 option to the interpreter to warn about features that are
3559 deprecated and will be changed/removed in Python 3.0.
3560
Georg Brandl2134e752007-05-21 20:34:16 +00003561- Patch #1686487: you can now pass any mapping after '**' in function
3562 calls.
3563
Collin Winter62903052007-05-18 23:11:24 +00003564- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003565 "except E as target:". This is to provide forwards compatibility
3566 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00003568- Deprecate BaseException.message as per PEP 352.
3569
Georg Brandl3ee81df2008-05-17 18:14:43 +00003570- Issue #1303614: don't expose object's __dict__ when the dict is

3572
Vinay Sajip8549ce32007-05-06 17:53:37 +00003573- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003574 setting a plain string, ie don't expand to single letter identifiers.
3575
Raymond Hettinger13936692007-04-11 18:40:58 +00003576- Request #1191699: Slices can now be pickled.

3580 remaining characters.
3581
Georg Brandl5cb76c12007-03-21 09:00:39 +00003582- Patch #1682205: a TypeError while unpacking an iterable is no longer
3583 masked by a generic one with the message "unpack non-sequence".
3584
Neal Norwitzaa754b72007-03-21 06:39:48 +00003585- Remove unused file Python/fmod.c.
3586
Guido van Rossum143b5642007-03-23 04:58:42 +00003587- Bug #1683368: The object.__init__() and object.__new__() methods are
3588 now stricter in rejecting excess arguments. The only time when
3589 either allows excess arguments is when it is not overridden and the
3590 other one is. For backwards compatibility, when both are
3591 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003592 warning later). Also, type.__init__() insists on the same signature
3593 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003595- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3596 object to complex using its __complex__() method before falling back
3597 to the __float__() method. Therefore, the functions in the cmath
3598 module now can operate on objects that define a __complex__()
3599 method.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003635- Patch #703779: unset __file__ in __main__ after running a file. This

3706 embedded in the string to convert.
3707
Georg Brandl846f73a2006-10-08 07:11:54 +00003708- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004188 AttributeError instead of an IOError when the server's response

Georg Brandl92a6bae2007-03-13 17:43:32 +00004222- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004223 are set for invalid interpolation sequences that would lead to

4280 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004673 time so that opening a database previously created with the DB_DUP
4674 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4675 opens. Specifically: dictionary assignment to a DB object will
4676 replace all values for a given key when the database allows
4677 duplicate values. DB users should use DB.put(k, v) when they want
4678 to store duplicates; not DB[k] = v.

4685 characters with ASCII value less than 32. Also, it correctly quotes
4686 dots only if they occur on a single line, as opposed to the previous
4687 behavior of quoting dots if they are the second character of any
4688 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004689
