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

10*Release date: XXXX-XX-XX*
11
12Core and Builtins
13-----------------
14
Mark Dickinson1b34d252010-01-01 17:27:30 +000015- Issue #5080: A number of functions and methods previously produced a
16 DeprecationWarning when passed a float argument where an integer was
17 expected. These functions and methods now raise TypeError instead.
18 The majority of the effects of this change are in the extension
19 modules, but some core functions and methods are affected: notably
20 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
21 methods.
22
Benjamin Peterson0f02d392009-12-30 19:34:10 +000023- Issue #7604: Deleting an unset slotted attribute did not raise an
24 AttributeError.
25
Mark Dickinson99d652e2009-12-30 12:12:23 +000026- Issue #7534: Fix handling of IEEE specials (infinities, nans,
27 negative zero) in ** operator. The behaviour now conforms to that
28 described in C99 Annex F.
29
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000030- Issue #7579: the msvcrt module now has docstrings for all its functions.
31
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000032- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
33 used to drop the time part of the result.
34
Mark Dickinson46572832009-12-27 14:55:57 +000035- Issue #1811: improve accuracy and cross-platform consistency for
36 true division of integers: the result of a/b is now correctly
37 rounded for ints a and b (at least on IEEE 754 platforms), and in
38 particular does not depend on the internal representation of a long.
39
Ezio Melottif84caf42009-12-24 22:25:17 +000040- Issue #6108: unicode(exception) and str(exception) should return the same
41 message when only __str__ (and not __unicode__) is overridden in the subclass.
42
Ronald Oussoren92919a62009-12-24 13:30:58 +000043- Issue #6834: replace the implementation for the 'python' and 'pythonw'
44 executables on OSX.
45
46 These executables now work properly with the arch(1) command:
47 ``arch -ppc python`` will start a universal binary version of python
48 in PPC mode (unlike previous releases).
49
R. David Murray0a0a1a82009-12-14 16:28:26 +000050- Issue #1680159: unicode coercion during an 'in' operation no longer masks
51 the underlying error when the coercion fails for the left hand operand.
52
Benjamin Peterson4895af42009-12-13 16:36:53 +000053- Issue #7491: Metaclass's __cmp__ method was ignored.
54
Antoine Pitrou2a08b422009-12-13 16:18:14 +000055- Issue #7466: segmentation fault when the garbage collector is called
56 in the middle of populating a tuple. Patch by Florent Xicluna.

63 Initial patch by Brian Curtin.
64
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +000065- Distutils now correctly identifies the build architecture as "x86_64"
Ezio Melotti569e61f2009-12-30 06:14:51 +000066 when building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +000067
Tarek Ziadé0479eb52009-12-21 23:37:44 +000068- Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest
69 file in text mode.
70
Tarek Ziadé2421d562009-12-20 23:23:34 +000071- Issue #7552: Removed line feed in the base64 Authorization header in
72 the Distutils upload command to avoid an error when PyPI reads it.
73 This occurs on long passwords. Initial patch by JP St. Pierre.
74
75- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +000076 Patch by Tatsuhiro Tsujikawa.
77
Benjamin Petersonddd392c2009-12-13 19:19:07 +000078- Issue #7349: Make methods of file objects in the io module accept None as an
79 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
80 the same as passing no argument.
81
Benjamin Petersonc4771d22009-12-13 17:31:31 +000082- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
83 like other file objects.
84
Lars Gustäbel92ca7562009-12-13 11:32:27 +000085- Issue #7357: tarfile no longer suppresses fatal extraction errors by
86 default.
87
Vinay Sajip5cc4e2a2009-12-11 09:16:01 +000088- Issue #7470: logging: fix bug in Unicode encoding fallback.

97-----
98
Mark Dickinson1b34d252010-01-01 17:27:30 +000099- Issue #5080: The argument parsing functions PyArg_ParseTuple,
100 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
101 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
102 arguments for integer format codes (other than 'L'): previously an
103 attempt to pass a float resulted in a DeprecationWarning; now it
104 gives a TypeError. For the 'L' format code (which previously had no
105 warning) there is now a DeprecationWarning.
106
Georg Brandl740cdc32009-12-28 08:34:58 +0000107- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

Benjamin Peterson6c99b4e2010-01-01 15:20:06 +0000115 --with-system-ffi flag is used.
Benjamin Petersonb4abef62010-01-01 15:18:38 +0000116
Benjamin Peterson2c196742009-12-31 03:17:18 +0000117- Issue #7609: Add a --with-system-expat option that causes the system's expat
118 library to be used for the pyexpat module instead of the one included with
119 Python.
120
Benjamin Peterson500ce232009-12-30 02:58:50 +0000121- Issue #7589: Only build the nis module when the correct header files are

133 with no arguments, doctest.py now gives a usage message.
134
R. David Murray98e3df32009-12-16 11:49:46 +0000135- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
136
R. David Murrayc7298ff2009-12-14 21:57:39 +0000137- Issue #7498: test_multiprocessing now uses test_support.find_unused_port

147Core and Builtins
148-----------------
149
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000150- Issue #7419: setlocale() could crash the interpreter on Windows when called
151 with invalid values.
152
Eric Smithc4ab8332009-11-29 17:40:57 +0000153- Issue #3382: 'F' formatting for float and complex now convert the
154 result to upper case. This only affects 'inf' and 'nan', since 'f'
155 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000156
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000157- Remove switch from "%f" formatting to "%g" formatting for floats
158 larger than 1e50 in absolute value.
159
Mark Dickinson18cfada2009-11-23 18:46:41 +0000160- Remove restrictions on precision when formatting floats. E.g.,
161 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
162 requested 120 significant digits instead.
163
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000164- Add Py3k warnings for parameter names in parenthesis.
165
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000166- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000167
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000168- Issue #7085: Fix crash when importing some extensions in a thread
169 on MacOSX 10.6.
170
Mark Dickinsonb678de82009-11-19 18:41:49 +0000171- Issue #7117: repr(x) for a float x returns a result based on the
172 shortest decimal string that's guaranteed to round back to x under
173 correct rounding (with round-half-to-even rounding mode).
174 Previously it gave a string based on rounding x to 17 decimal digits.
175 repr(x) for a complex number behaves similarly. On platforms where
176 the correctly-rounded strtod and dtoa code is not supported (see below),
177 repr is unchanged.
178
179- Issue #7117: On almost all platforms: float-to-string and
180 string-to-float conversions within Python are now correctly rounded.
181 Places these conversions occur include: str for floats and complex
182 numbers; the float and complex constructors; old-style and new-style
183 numeric formatting; serialization and deserialization of floats and
184 complex numbers using marshal, pickle and json; parsing of float and
185 imaginary literals in Python code; Decimal-to-float conversion.
186
187 The conversions use a Python-adapted version of David Gay's
188 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
189 functions. This code is supported on Windows, and on Unix-like
190 platforms using gcc, icc or suncc as the C compiler. There may be a
191 small number of platforms on which correct operation of this code
192 cannot be guaranteed, so the code is not used: notably, this applies
193 to platforms where the C double format is not IEEE 754 binary64, and
194 to platforms on x86 hardware where the x87 FPU is set to 64-bit
195 precision and Python's configure script is unable to determine how
196 to change the FPU precision. On these platforms conversions use the
197 platform strtod and dtoa, as before.
198
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000199- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000200 now uses the correctly-rounded string <-> float conversions
201 described above (when available), and so produces correctly rounded
202 results that will display nicely under the float repr. There are
203 two related small changes: (1) round now accepts any class with an
204 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000205 floats for the second argument), and (2) an excessively large second
206 integer argument (e.g., round(1.234, 10**100)) no longer raises an
207 exception.
208
Philip Jenveyfab8be22009-11-17 02:42:26 +0000209- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
210
Benjamin Petersone36199b2009-11-12 23:39:44 +0000211- Fix several issues with compile(). The input can now contain Windows and Mac
212 newlines and is no longer required to end in a newline.
213

215 unicode string.
216
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000217- Issue #7244: itertools.izip_longest() no longer ignores exceptions
218 raised during the formation of an output tuple.
219

221
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000222- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

224 interpreter is killed. Patch by Adam Olsen.
225
Eric Smithc12781a2009-10-19 14:38:14 +0000226- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and
227 note that they are unsafe and deprecated.
228
Vinay Sajip03d5c342009-10-16 14:06:44 +0000229- Issue #7120: logging: Removed import of multiprocessing which is causing
230 crash in GAE.
231
Benjamin Peterson196b0922009-10-15 15:44:46 +0000232- Issue #7140: The __dict__ of a module should not be cleared unless the module
233 is the only object holding a reference to it.
234
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000235- Issue #1754094: Improve the stack depth calculation in the compiler.
236 There should be no other effect than a small decrease in memory use.
237 Patch by Christopher Tur Lesniewski-Laas.
238
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000239- Issue #7084: Fix a (very unlikely) crash when printing a list from one

241
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000242- Issue #1571184: The Unicode database contains properties for more characters.

Raymond Hettinger62641e92009-06-23 20:59:43 +0000313- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
314 because it wasn't recognized as a sequence).
315
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +0000316- Issue #6289: Encoding errors from compile() were being masked.
317
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000318- When no module is given in a relative import, the module field of the
319 ImportFrom AST node is now None instead of an empty string.
320
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000321- Assignment to None using import statements now raises a SyntaxError.
322
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +0000323- Issue #4547: When debugging a very large function, it was not always
324 possible to update the lineno attribute of the current frame.
325
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000326- Issue #5330: C functions called with keyword arguments were not reported by
Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000327 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000328
Raymond Hettinger578a2282009-05-29 04:58:52 +0000329- Issue #5982: staticmethod and classmethod now expose the wrapped
330 function with __func__.
331
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000332- Added support for multiple context managers in the same with-statement.
333 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +0000334
Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000335- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
336 statement and correctly lookup the __enter__ and __exit__ special methods.
337
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000338- Issue #5829: complex("1e500") no longer raises OverflowError. This
339 makes it consistent with float("1e500") and interpretation of real
340 and imaginary literals.
341
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000342- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
343
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000344- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
345 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000346
R. David Murray525cffc2009-05-13 13:07:14 +0000347- Issue #5994: the marshal module now has docstrings.
348
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000349- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
350 (1) inf and nan strings with trailing whitespace were incorrectly
351 rejected; (2) parsing of strings representing infinities and nans
352 was locale aware; and (3) the interpretation of fromhex('-nan')
353 didn't match that of float('-nan').
354
Eric Smitha985a3a2009-05-05 18:26:08 +0000355- Issue #5920: For float.__format__, change the behavior with the
356 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
357 to be like 'g' but with at least one decimal point and with a
358 default precision of 12. Previously, the behavior the same but with
359 a default precision of 6. This more closely matches str(), and
360 reduces surprises when adding alignment flags to the empty
361 presentation type. This also affects the new complex.__format__ in
362 the same way.
363
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000364- Issue #5890: in subclasses of 'property' the __doc__ attribute was
365 shadowed by classtype's, even if it was None. property now
366 inserts the __doc__ into the subclass instance __dict__.
367
Antoine Pitrou653dece2009-05-04 18:32:32 +0000368- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
369 sequences. Patch by Nick Barnes and Victor Stinner.
370
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000371- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000372 format(complex(1, 2./3), '.5') now produces a sensible result.
373
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000374- Issue #5864: Fix empty format code formatting for floats so that it
375 never gives more than the requested number of significant digits.
376
Eric Smithcac7af62009-04-27 19:04:37 +0000377- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
378 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.

381 titlecase, but not their own uppercase.
382
Eric Smith068f0652009-04-25 21:40:15 +0000383- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
384 _PyOS_double_to_string or PyOS_double_to_string.
385
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000386- Issue #5283: Setting __class__ in __del__ caused a segfault.
387
Mark Dickinson95bc9802009-04-24 12:46:53 +0000388- Issue #5816: complex(repr(z)) now recovers z exactly, even when
389 z involves nans, infs or negative zeros.
390
Eric Smithaca19e62009-04-22 13:29:05 +0000391- Implement PEP 378, Format Specifier for Thousands Separator, for
392 floats, ints, and longs.
393
394- Issue #5515: 'n' formatting for ints, longs, and floats handles
395 leading zero formatting poorly.
396
397- Issue #5772: For float.__format__, don't add a trailing ".0" if
398 we're using no type code and we have an exponent.
399
Mark Dickinson6736cf82009-04-20 21:13:33 +0000400- Issue #3166: Make long -> float (and int -> float) conversions
401 correctly rounded.
402
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000403- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
404 some builtin types.
405
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000406- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000407 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000408
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000409- Issue #5759: float() didn't call __float__ on str subclasses.
410
Georg Brandl3c4a5462009-04-12 12:08:12 +0000411- Issue #5704: the "-3" command-line option now implies "-t".
412
R. David Murray0374a822009-04-09 21:54:50 +0000413- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
414 its clarity and its speed.
415
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000416- Issue #2396: the memoryview object was backported from Python 3.1.
417
Georg Brandld3f03fa2009-04-02 18:09:04 +0000418- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

Brett Cannon15ba4da2009-04-01 18:03:59 +0000421- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
422
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000423- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
424 the end sys.path, for compatibility with the system install of Python.
425
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000426- Issue #4688: Add a heuristic so that tuples and dicts containing only
427 untrackable objects are not tracked by the garbage collector. This can
428 reduce the size of collections and therefore the garbage collection overhead
429 on long-running programs, depending on their particular use of datatypes.
430
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000431- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
432 improve its performance. Long divisions and remainder operations
433 are now between 50% and 150% faster.
434
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000435- Issue #4258: Make it possible to use base 2**30 instead of base
436 2**15 for the internal representation of integers, for performance
437 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
438 --enable-big-digits option to configure, which overrides the
439 default. Add sys.long_info structseq to provide information about
440 the internal format.
441
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000442- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
443 result traceback.__members__ no longer exists.)
444
Mark Dickinson6b265f12009-03-18 16:07:26 +0000445- Issue #4474: PyUnicode_FromWideChar now converts characters outside
446 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
447 and sizeof(Py_UNICODE) == 2.
448
Eric Smith6f42edb2009-03-14 11:57:26 +0000449- Issue #5237: Allow auto-numbered fields in str.format(). For
450 example: '{} {}'.format(1, 2) == '1 2'.
451
Brett Cannon6c4cff02009-03-11 04:51:06 +0000452- Issue #3652: Make the 'line' argument for warnings.showwarning() a
453 requirement. Means the DeprecationWarning from Python 2.6 can go away.
454
Eric Smithe9fb6862009-02-20 14:02:36 +0000455- Issue #5247: Improve error message when unknown format codes are
456 used when using str.format() with str, unicode, long, int, and
457 float arguments.
458
Raymond Hettinger08259e82009-02-18 23:10:19 +0000459- Running Python with the -3 option now also warns about classic division
460 for ints and longs.
461
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000462- Issue #5260: Long integers now consume less memory: average
463 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
464 on a 64-bit system.
465
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000466- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
467 rotating the object pointer by 4 bits to the right.
468
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000469- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
470 it now forces its argument to double before testing for infinity.
471
Benjamin Petersone18ef192009-01-20 14:21:16 +0000472- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
473
Georg Brandl29c6a282009-04-05 20:23:13 +0000474- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000475 were suppressing all exceptions. These include list(), filter(), map(),
476 zip(), and bytearray().
477
Benjamin Peterson596d3062009-01-19 15:42:23 +0000478- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
479 functions.
480
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000481- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

485
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000486- Issue #4935: The overflow checking code in the expandtabs() method common
487 to str, bytes and bytearray could be optimized away by the compiler, letting
488 the interpreter segfault instead of raising an error.
489
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000490- Issue #3720: Fix a crash when an iterator modifies its class and removes its
491 __next__ method.
492
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000493- Issue #4893: Use NT threading on CE.

496
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000497- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
498 collecting the oldest generation) so that allocating lots of objects without
499 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000500 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000501 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

504
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000505- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
506 an existing .py counterpart, override the co_filename attributes of all
507 code objects if the original filename is obsolete (which can happen if the
508 file has been renamed, moved, or if it is accessed through different paths).
509 Patch by Ziga Seilnacht and Jean-Paul Calderone.
510
Martin v. Löwis5344c992009-01-02 20:32:55 +0000511- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000513- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
514 file with `str' filename on Windows.
515
Antoine Pitrouaa687902009-01-01 14:11:22 +0000516- Issue #3680: Reference cycles created through a dict, set or deque iterator
517 did not get collected.
518
Nick Coghlan180e4002008-12-30 01:18:48 +0000519- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
520 where the tp_hash and tp_dict slots are both NULL.
521
Benjamin Peterson7af65562008-12-29 17:56:58 +0000522- Issue #4764: With io.open, IOError.filename is set when trying to open a
523 directory on POSIX systems.
524
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000525- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
526 systems.

529 bytearray.translate(). It was always allowed for bytes.translate().
530
Skip Montanarof205c132008-12-23 03:30:15 +0000531- Added test case to ensure attempts to read from a file opened for writing
532 fail.
533
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000534- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
535 print elapsed times, not only when some objects are uncollectable /
536 unreachable. Original patch by Neil Schemenauer.
537
Mark Dickinson1a707982008-12-17 16:14:37 +0000538- Issue #3439: Add a bit_length method to int and long.

Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000543- Issue #4597: Fixed exception handling when the __exit__ function of a
544 context manager returns a value that cannot be converted to a bool.
545
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000546- Issue #4597: Fixed several opcodes that weren't always propagating
547 exceptions.
548
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000549- Issue #4445: Replace "sizeof(PyStringObject)" with
550 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
551 str instances. On a typical machine this saves 3 bytes of memory
552 (on average) per string allocation.
553
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000554- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
555 interpreter to abort ("Fatal Python error: Could not reset the stack!")
556 instead of throwing a MemoryError.
557
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000558- Issue #3689: The list reversed iterator now supports __length_hint__
559 instead of __len__. Behavior now matches other reversed iterators.
560
Benjamin Petersonc078f922008-11-21 22:27:24 +0000561- Issue #4367: Python would segfault during compiling when the unicodedata
562 module couldn't be imported and \N escapes were present.
563
Vinay Sajip213faca2008-12-03 23:22:58 +0000564- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000565 method on file objects with closefd=False. The file descriptor is still
566 kept open but the file object behaves like a closed file. The ``FileIO``
567 object also got a new readonly attribute ``closefd``.
568
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000569- Issue #4348: Some bytearray methods returned that didn't cause any change to
570 the bytearray, returned the same bytearray instead of a copy.
571
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000572- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
573
Benjamin Peterson273c2332008-11-17 22:39:09 +0000574- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
575
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000576- Issue #4048: The parser module now correctly validates relative imports.
577
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000578- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
579 exec statement.
580
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000581- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
582 method does not return iterators for the 4th and 5th items.
583
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000584- Issue #4209: Enabling unicode_literals and the print_function in the same
585 __future__ import didn't work.
586
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000587- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000588 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000589
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000590- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
591 returned a path longer than MAX_PATH. (But It's doubtful this code path is
592 really executed because I cannot move to such directory on win2k)
593
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000594- Issue #4069: When set.remove(element) is used with a set element, the element
595 is temporarily replaced with an equivalent frozenset. But the eventual
596 KeyError would always report the empty frozenset([]) as the missing key. Now
597 it correctly refers to the initial element.
598
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000599- Issue #4509: Various issues surrounding resize of bytearray objects to
600 which there are buffer exports.

618 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
619 step. This avoids problems with counting UTF-8 bytes that ignores the effect
620 of using the replace error handler in PyUnicode_DecodeUTF8().
621

627 Valgrind. This gives improved memory leak detection when running

1167 allows for much simpler resource allocation and deallocation during tests.
1168
1169- Issue #3379: unittest.main now takes an optional exit argument. If False main
1170 doesn't call sys.exit allowing it to be used from the interactive interpreter.

1180
Michael Foord345b2fe2009-04-02 03:20:38 +00001181- Issue #5663: better failure messages for unittest asserts. Default assertTrue
1182 and assertFalse messages are now useful. TestCase has a longMessage attribute.
1183 This defaults to False, but if set to True useful error messages are shown in
1184 addition to explicit messages passed to assert methods.

1865 leak-chasing test runs give sensible results. The previous method of
1866 reaping threads could return successfully while some Thread objects were

2006-----------------
2007
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002008- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2009
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002010- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2011 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2012 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2013 ``printf`` function, whereas PyString_FromFormat has an independent
2014 implementation and uses "%zd" on all platforms for size_t values.
2015 This makes a difference on win64, where ``printf`` needs "%Id" to display
2016 64bit values.
2017
Benjamin Peterson97179b02008-09-09 20:55:01 +00002018- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2019 error.
2020
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002021- Issue #3777: long() applied to a float object now always return a long
2022 object; previously an int would be returned for small values. the __long__
2023 method is allowed to return either an int or a long, but the behaviour of
2024 float objects should not change to respect backward compatibility.
2025
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002026- Issue #3751: str.rpartition would perform a left-partition when called with
2027 a unicode argument.
2028
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002029- Issue #3683: Fix compilation when --without-threads is given.
2030
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002031- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002032 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002033 was correctly parsed but parsing of subsequent arguments failed.
2034
Vinay Sajip35e3b032008-09-01 14:33:59 +00002035- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002036 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2037 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2038 when given a tuple of classes as second argument, were looking up
2039 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2040 type object.
2041
Neal Norwitz18aa3882008-08-24 05:04:52 +00002042- Fix crashes on memory allocation failure found with failmalloc.
2043
2044- Fix memory leaks found with valgrind and update suppressions file.
2045
2046- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2047
2048- Fix problem using wrong name in decimal module reported by pychecker.
2049
Christian Heimes7d4c3172008-08-22 19:47:25 +00002050- Silenced another compiler warning about a used but not defined
2051 function 'stringlib_contains_obj'.
2052

Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002056- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2057 library targets in the Makefile.
2058
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002059- Issue #1204: The configure script now tests for additional libraries
2060 that may be required when linking against readline. This fixes issues
2061 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00002084- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002085 return a list or None rather than a custom object.

2111 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2112 for catch_warnings() also led to an improvement in the raising of a
2113 DeprecationWarning related to warnings.warn_explicit().
2114

2180================================
2181
Barry Warsaw07a4a382008-08-21 01:15:08 +00002182*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002183
2184Core and Builtins
2185-----------------
2186
Guido van Rossumf8402962008-08-20 15:01:50 +00002187- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2188 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2189 extensions do not automatically benefit from the class attribute
2190 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2191 to their tp_flags field if they care. This is a backwards
2192 compatibility feature; in 3.0, all types will use the cache by
2193 default.
2194
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002195- Keyword arguments can now follow starred arguments. (``f(a, *args,
2196 keyword=23)`` is now valid syntax.)
2197
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002198- ctypes function pointers that are COM methods have a boolean True
2199 value again.
2200
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002201- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2202 by denying s# to parse objects that have a releasebuffer procedure,
2203 and introducing s*.
2204
Georg Brandl1e13ea92008-08-11 09:07:59 +00002205- Issue #3537: Fix an assertion failure when an empty but presized dict
2206 object was stored in the freelist.
2207
Mark Dickinsonb6467572008-08-04 21:30:09 +00002208- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2209 ValueError consistently across platforms.
2210
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002211- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2212 (64bit Unix, for example), unichr() would truncate its argument and return
2213 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2214
Neal Norwitze7d8be82008-07-31 17:17:14 +00002215- Apply security patches from Apple.
2216
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002217- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2218 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2219
Antoine Pitrou92f82162008-07-25 22:22:08 +00002220- Issue #1819: function calls with several named parameters are now on
2221 average 35% faster (as measured by pybench).
2222
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002223- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2224 the python debugger steps into a class statement: the free variables (local
2225 variables defined in an outer scope) would be deleted from the outer scope.
2226
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002227- Issue #2620: Overflow checking when allocating or reallocating memory
2228 was not always being done properly in some python types and extension
2229 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2230 all been updated to perform better checks and places in the code that
2231 would previously leak memory on the error path when such an allocation
2232 failed have been fixed.

2240 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2241
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002242- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2243 version reported by these tools does not necessarily follow the python
2244 version numbering scheme, so the module is less strict when parsing it.
2245
Nick Coghlanf70385a2008-08-18 12:42:46 +00002246- Issue #2235: Added Py3k warnings for types which will become unhashable
2247 under the stricter __hash__ inheritance rules in 3.0. Several types
2248 which did not meet the rules for hash invariants and were already
2249 unhashable in 3.0 have now been explicitly flagged as unhashable in
2250 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2251 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2252
Brett Cannon88f801d2008-08-18 00:46:22 +00002253- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2254 imported into the module but exposed as part of the module's API.
2255
Brett Cannon7b96f072008-08-18 00:41:11 +00002256- Remove an unneeded import of abc.ABCMeta from 'inspect'.

2261
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002262- Issue #3575: Incremental decoder's decode function now takes bytearray
2263 by using 's*' instead of 't#'.
2264
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002265- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002266 fails unicode conversion on 2nd parameter. (windows only)
2267
Facundo Batista94f243a2008-08-17 03:38:39 +00002268- Issue 2464. urllib2 now supports a malformation in the URL received
2269 in a redirect.

2300 to _sre.compile() will now be rejected. This should not affect anybody
2301 since the re.compile() function never generates invalid re-bytecode.

Brett Cannon3aa2a492008-08-06 22:28:09 +00002307- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2308 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00002322 asking for a specific length. This problem only affected files opened
2323 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002324

2349 file name rather than a ZipInfo instance, so files are extracted with
2350 mode 0600 rather than 000 under Unix.
2351
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002352- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2365 interaction with the tp_hash slot (added in 2.6b2) are now documented
2366
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002367- Issue #643841: The language reference now provides more detailed

2379-----------------
2380
Georg Brandl3e483f62008-07-16 22:57:41 +00002381- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2382 its methods now allow for items objects that can be converted to
2383 an integer using operator.index().
2384
Mark Dickinson64b7e502008-07-16 09:40:03 +00002385- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2386 produced a ValueError instead of giving the correct float.
2387
Eric Smitha5fa5a22008-07-16 00:11:49 +00002388- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2389 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2390
Mark Dickinson7103aa42008-07-15 19:08:33 +00002391- Issue #3008: the float type has a new instance method 'float.hex'
2392 and a new class method 'float.fromhex' to convert floating-point
2393 numbers to and from hexadecimal strings, respectively.
2394
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002395- Issue #2235: __hash__ is once again inherited by default. To allow
2396 collections.Hashable to remain meaningful in the presence of the
2397 default hash implementation (object.__hash__), it is now possible
2398 to explicit block inheritance of hash by setting __hash__=None at
2399 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2400 level.
2401
Nick Coghlanb028f502008-07-13 14:52:36 +00002402- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2403 the parent module cannot be found while performing an absolute import.
2404 This means that an incorrectly defined __package__ attribute will
2405 now only prevent relative imports in that module rather than causing
2406 all imports from that module to fail.
2407
Nick Coghlan14ff9942008-07-08 14:21:42 +00002408- Issue #2517: Allow unicode messages in Exceptions again by correctly

2418 another thread's dictionary.
2419
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002420- Issue #3004: Minor change to slice.indices(): the start and stop
2421 arguments are now treated identically, making the behaviour easier
2422 to describe and understand. For example, slice(None, -10,
2423 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2424 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2425 10, -1).
2426
Georg Brandl278fc502008-07-19 12:46:12 +00002427- Issue #3219: Calling a function with repeated keyword arguments,
2428 f(a=2, a=23), would not cause a syntax error. This was a regression
2429 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002430
Georg Brandl278fc502008-07-19 12:46:12 +00002431- Issue #2862: Make int and float freelist management consistent with
2432 other freelists. Changes their CompactFreeList apis into

2439 api functions without holding the GIL, which could lead to a fatal
2440 error when they failed.
2441
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002442- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002467- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2468 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002469 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002470 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002486- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2876
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002877- On MacOS X it is now possible to install the framework in 64-bit
2878 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002879 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002880
2881 This is controlled by the configure argument ``--with-universal-archs``:
2882
2883 - ``--with-universal-archs=all``: install 4-way universal
2884
2885 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2886
2887 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2888
2889 This option should be used in combination with ``--enable-universalsdk=``.
2890
2891 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 +00002941- Issue #1631171: Re-implement the 'warnings' module in C (the
2942 original Python code has been kept as backup). This will allow for
2943 using the 'warning's machinery in such places as the parser where
2944 use of pure Python code is not possible. Both the ``showarning()``
2945 and ``formatwarning()`` gain an optional 'line' argument which is
2946 not called by default for backwards-compatibility reasons. Setting
2947 ``warnings.showwarning()`` to an implementation that lacks support
2948 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002973- The getpass module has been improved on Unix. It now uses /dev/tty
2974 by default and uses stderr instead of stdout. A GetPassWarning is
2975 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002990- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002991 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003011- Issue #2550: The approach used by client/server code for obtaining
3012 ports to listen on in network-oriented tests has been refined in an
3013 effort to facilitate running multiple instances of the entire
3014 regression test suite in parallel without issue.
3015 test_support.bind_port() has been fixed such that it will always
3016 return a unique port -- which wasn't always the case with the
3017 previous implementation, especially if socket options had been set
3018 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3019 new implementation of bind_port() will actually raise an exception
3020 if it is passed an AF_INET/SOCK_STREAM socket with either the
3021 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3022 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3023 the socket it's been passed. This currently only applies to
3024 Windows. This option prevents any other sockets from binding to the
3025 host/port we've bound to, thus removing the possibility of the
3026 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3027 when a second SOCK_STREAM socket binds and accepts to a host/port
3028 that's already been bound by another socket. The optional preferred
3029 port parameter to bind_port() has been removed. Under no
3030 circumstances should tests be hard coding ports!
3031
3032 test_support.find_unused_port() has also been introduced, which will
3033 pass a temporary socket object to bind_port() in order to obtain an
3034 unused port. The temporary socket object is then closed and
3035 deleted, and the port is returned. This method should only be used
3036 for obtaining an unused port in order to pass to an external program
3037 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3038 a parameter to a server-oriented class that doesn't give you direct
3039 access to the underlying socket used.
3040
3041 Finally, test_support.HOST has been introduced, which should be used
3042 for the host argument of any relevant socket calls (i.e. bind and
3043 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003044
3045 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003046 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003047 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3048 test_asynchat and test_socket_ssl.
3049
Georg Brandl3ee81df2008-05-17 18:14:43 +00003050 It is now possible for multiple instances of the regression test
3051 suite to run in parallel without issue.

3318-----------------
3319
Fred Drakea8ee94b2008-03-01 02:45:07 +00003320- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003321 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003326
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003327- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003328 issue 215555 for a discussion.
3329
Eric Smitha73fbe72008-02-23 03:09:44 +00003330- Added the future_builtins module, which contains hex() and oct().
3331 These are the PEP 3127 version of these functions, designed to be
3332 compatible with the hex() and oct() builtins from Python 3.0. They
3333 differ slightly in their output formats from the existing, unchanged
3334 Python 2.6 builtins. The expected usage of the future_builtins
3335 module is:
3336 from future_builtins import hex, oct
3337
Eric Smith7ef40bf2008-02-20 23:34:22 +00003338- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3339 exponents for exponents with absolute value < 100. Follows C99
3340 standard. This is a change on Windows, which would use 3 digits.
3341 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3342 so that any alterations it does to the resulting string will be
3343 available in stringlib/formatter.h (for float.__format__).
3344
Eric Smith5a3c1352008-02-19 13:21:56 +00003345- Implemented PEP 3101, Advanced String Formatting. This adds a new
3346 builtin format(); a format() method for str and unicode; a
3347 __format__() method to object, str, unicode, int, long, float, and
3348 datetime; the class string.Formatter; and the C API
3349 PyObject_Format().
3350
Georg Brandl3ee81df2008-05-17 18:14:43 +00003351- Fixed several potential crashes, all caused by specially crafted
3352 __del__ methods exploiting objects in temporarily inconsistent
3353 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003354
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003355- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003356 prevent a possible crash: an Abstract Base Class would try to access
3357 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003358

3360 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003361
Georg Brandl3ee81df2008-05-17 18:14:43 +00003362- Clear all free lists during a gc.collect() of the highest generation
3363 in order to allow pymalloc to free more arenas. Python may give back

Georg Brandl3ee81df2008-05-17 18:14:43 +00003366- Issue #2045: Fix an infinite recursion triggered when printing a
3367 subclass of collections.defaultdict, if its default_factory is set
3368 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003369
Christian Heimesf75dbef2008-02-08 00:11:31 +00003370- Fixed a minor memory leak in dictobject.c. The content of the free
3371 list was not freed on interpreter shutdown.
3372
Georg Brandl3ee81df2008-05-17 18:14:43 +00003373- Limit free list of method and builtin function objects to 256
3374 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3377 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003378 to compact the internal free lists of pre-allocted ints and floats.
3379
Georg Brandl3ee81df2008-05-17 18:14:43 +00003380- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3381 calls. Python expected the return type int but the fork familie
3382 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003383
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3385 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3388 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003389
Georg Brandl3ee81df2008-05-17 18:14:43 +00003390- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003393- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3394 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003395
Georg Brandl3ee81df2008-05-17 18:14:43 +00003396- Patch #1473257: generator objects gain a gi_code attribute. This is
3397 the same object as the func_code attribute of the function that
3398 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003399
Georg Brandl3ee81df2008-05-17 18:14:43 +00003400- Issue #1920: "while 0" statements were completely removed by the
3401 compiler, even in the presence of an "else" clause, which is
3402 supposed to be run when the condition is false. Now the compiler
3403 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003404
Guido van Rossumeead05f2008-01-24 18:21:02 +00003405- A few crashers fixed: weakref_in_del.py (issue #1377858);
3406 loosing_dict_ref.py (issue #1303614, test67.py);
3407 borrowed_ref_[34].py (not in tracker).
3408
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003409- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003410 suppressed while an extension is loaded by calling SetErrorMode in
3411 dynload_win.c. The error is still reported properly.
3412
Georg Brandl3ee81df2008-05-17 18:14:43 +00003413- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003414 several extension methods and modules do not work without unicode
3415 support.
3416
Georg Brandl26543b12008-01-21 18:36:51 +00003417- Issue #1882: when compiling code from a string, encoding cookies in the
3418 second line of code were not always recognized correctly.
3419
Georg Brandl14404b62008-01-19 19:27:05 +00003420- Issue #1679: "0x" was taken as a valid integer literal.
3421
Georg Brandl6caad7d2008-01-26 14:19:22 +00003422- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003423 added.
3424
Christian Heimesc94e2b52008-01-14 04:13:37 +00003425- sys.float_info / PyFloat_GetInfo: The floating point information
3426 object was converted from a dict to a specialized structseq object.
3427
Georg Brandl3ee81df2008-05-17 18:14:43 +00003428- Patch #1816: Added sys.flags structseq. It exposes the status of
3429 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003430
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431- Objects/structseq.c: Implemented new structseq representation. The
3432 patch makes structseqs (e.g. the return value of os.stat) more
3433 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- Patch #1700288: added a type attribute cache that caches method
3436 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003437
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003438- Bug #1776: __import__() no longer accepts filenames on any platform.
3439 The first parameter to __import__() must be a valid module name.

3442
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3444 envvar and sys.dont_write_bytecode attribute. All these can be set
3445 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003446
Georg Brandl3ee81df2008-05-17 18:14:43 +00003447- Improve some exception messages when Windows fails to load an
3448 extension module. Now we get for example '%1 is not a valid Win32
3449 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003450

Christian Heimes0a8143f2007-12-18 23:22:54 +00003456- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003457 and INF. float("nan"), float("inf") and float("-inf") now work on
3458 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003459
Georg Brandl3ee81df2008-05-17 18:14:43 +00003460- Compiler now generates simpler and faster code for dictionary
3461 literals. The oparg for BUILD_MAP now indicates an estimated
3462 dictionary size. There is a new opcode, STORE_MAP, for adding
3463 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003492- Patch #1739468: Directories and zipfiles containing a __main__.py
3493 file can now be directly executed by passing their name to the
3494 interpreter. The directory/zipfile is automatically inserted as the
3495 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003497- Issue #1265: Fix a problem with sys.settrace, if the tracing
3498 function uses a generator expression when at the same time the
3499 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003500
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003501- sets and frozensets now have an isdisjoint() method.
3502

3504
Neal Norwitz44f326e2007-10-05 05:29:17 +00003505- Fix warnings found by the new version of the Coverity checker.
3506
Georg Brandl3ee81df2008-05-17 18:14:43 +00003507- The enumerate() builtin function is no longer bounded to sequences
3508 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3509 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003510
Georg Brandl3ee81df2008-05-17 18:14:43 +00003511- Issue #1686386: Tuple's tp_repr did not take into account the
3512 possibility of having a self-referential tuple, which is possible
3513 from C code. Nor did object's tp_str consider that a type's tp_str
3514 could do something that could lead to an inifinite recursion.
3515 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3516 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003517
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518- Issue #1164: It was possible to trigger deadlock when using the
3519 'print' statement to write to a file since the GIL was not released
3520 as needed. Now PyObject_Print() does the right thing along with
3521 various tp_print implementations of the built-in types and those in
3522 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003523
Georg Brandl3ee81df2008-05-17 18:14:43 +00003524- Issue #1147: Exceptions were directly allowing string exceptions in
3525 their throw() method even though string exceptions no longer
3526 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003527
Georg Brandl3ee81df2008-05-17 18:14:43 +00003528- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00003530
Brett Cannon1e534b52007-09-07 04:18:30 +00003531- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532 PyObject_Call() never calling back out to Python code to trigger
3533 recursion depth updates/checks. Required the creation of a static
3534 RuntimeError instance in case normalizing an exception put the
3535 recursion check value past its limit. Fixes crashers
3536 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003537

Neal Norwitz0ac60192007-05-27 04:08:54 +00003551- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003552 __*__ attributes. (Some already existed, e.g., __doc__ and
3553 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003554
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003555- Add -3 option to the interpreter to warn about features that are

3557
Georg Brandl2134e752007-05-21 20:34:16 +00003558- Patch #1686487: you can now pass any mapping after '**' in function
3559 calls.
3560
Collin Winter62903052007-05-18 23:11:24 +00003561- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003562 "except E as target:". This is to provide forwards compatibility
3563 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00003565- Deprecate BaseException.message as per PEP 352.
3566
Georg Brandl3ee81df2008-05-17 18:14:43 +00003567- Issue #1303614: don't expose object's __dict__ when the dict is

3569
Vinay Sajip8549ce32007-05-06 17:53:37 +00003570- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003571 setting a plain string, ie don't expand to single letter identifiers.
3572
Raymond Hettinger13936692007-04-11 18:40:58 +00003573- Request #1191699: Slices can now be pickled.
3574
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003575- Request #1193128: str.translate() now allows a None argument for

3577 remaining characters.
3578
Georg Brandl5cb76c12007-03-21 09:00:39 +00003579- Patch #1682205: a TypeError while unpacking an iterable is no longer
3580 masked by a generic one with the message "unpack non-sequence".
3581
Neal Norwitzaa754b72007-03-21 06:39:48 +00003582- Remove unused file Python/fmod.c.
3583
Guido van Rossum143b5642007-03-23 04:58:42 +00003584- Bug #1683368: The object.__init__() and object.__new__() methods are
3585 now stricter in rejecting excess arguments. The only time when
3586 either allows excess arguments is when it is not overridden and the
3587 other one is. For backwards compatibility, when both are
3588 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003589 warning later). Also, type.__init__() insists on the same signature
3590 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003592- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3593 object to complex using its __complex__() method before falling back
3594 to the __float__() method. Therefore, the functions in the cmath
3595 module now can operate on objects that define a __complex__()
3596 method.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003632- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003702- Bug #1545497: when given an explicit base, int() did ignore NULs
3703 embedded in the string to convert.
3704
Georg Brandl846f73a2006-10-08 07:11:54 +00003705- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004144 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004185 AttributeError instead of an IOError when the server's response
4186 didn't contain a valid HTTP status line.

4218
Georg Brandl92a6bae2007-03-13 17:43:32 +00004219- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220 are set for invalid interpolation sequences that would lead to
4221 errors on reading back those values.

4277 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004670 time so that opening a database previously created with the DB_DUP
4671 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4672 opens. Specifically: dictionary assignment to a DB object will
4673 replace all values for a given key when the database allows
4674 duplicate values. DB users should use DB.put(k, v) when they want
4675 to store duplicates; not DB[k] = v.

4682 characters with ASCII value less than 32. Also, it correctly quotes
4683 dots only if they occur on a single line, as opposed to the previous
4684 behavior of quoting dots if they are the second character of any
4685 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004686
