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
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

Ezio Melotti569e61f2009-12-30 06:14:51 +000074 when building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +000075
Tarek Ziadé0479eb52009-12-21 23:37:44 +000076- Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest

82
83- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +000084 Patch by Tatsuhiro Tsujikawa.
85
Benjamin Petersonddd392c2009-12-13 19:19:07 +000086- Issue #7349: Make methods of file objects in the io module accept None as an
87 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
88 the same as passing no argument.
89
Benjamin Petersonc4771d22009-12-13 17:31:31 +000090- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
91 like other file objects.
92
Lars Gustäbel92ca7562009-12-13 11:32:27 +000093- Issue #7357: tarfile no longer suppresses fatal extraction errors by
94 default.

111 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
112 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
113 arguments for integer format codes (other than 'L'): previously an
114 attempt to pass a float resulted in a DeprecationWarning; now it
115 gives a TypeError. For the 'L' format code (which previously had no
116 warning) there is now a DeprecationWarning.
117
Georg Brandl740cdc32009-12-28 08:34:58 +0000118- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

Benjamin Petersonb4abef62010-01-01 15:18:38 +0000127
Benjamin Peterson2c196742009-12-31 03:17:18 +0000128- Issue #7609: Add a --with-system-expat option that causes the system's expat
129 library to be used for the pyexpat module instead of the one included with
130 Python.

Benjamin Peterson3513c872009-12-05 18:48:13 +0000156*Release date: 2009-12-05*
Barry Warsaw12582c92008-10-02 03:33:51 +0000157
158Core and Builtins
159-----------------
160
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000161- Issue #7419: setlocale() could crash the interpreter on Windows when called
162 with invalid values.
163
Eric Smithc4ab8332009-11-29 17:40:57 +0000164- Issue #3382: 'F' formatting for float and complex now convert the
165 result to upper case. This only affects 'inf' and 'nan', since 'f'
166 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000167
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000168- Remove switch from "%f" formatting to "%g" formatting for floats
169 larger than 1e50 in absolute value.
170
Mark Dickinson18cfada2009-11-23 18:46:41 +0000171- Remove restrictions on precision when formatting floats. E.g.,
172 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
173 requested 120 significant digits instead.
174
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000175- Add Py3k warnings for parameter names in parenthesis.
176
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000177- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000178
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000179- Issue #7085: Fix crash when importing some extensions in a thread
180 on MacOSX 10.6.
181
Mark Dickinsonb678de82009-11-19 18:41:49 +0000182- Issue #7117: repr(x) for a float x returns a result based on the
183 shortest decimal string that's guaranteed to round back to x under
184 correct rounding (with round-half-to-even rounding mode).
185 Previously it gave a string based on rounding x to 17 decimal digits.
186 repr(x) for a complex number behaves similarly. On platforms where
187 the correctly-rounded strtod and dtoa code is not supported (see below),
188 repr is unchanged.
189
190- Issue #7117: On almost all platforms: float-to-string and
191 string-to-float conversions within Python are now correctly rounded.
192 Places these conversions occur include: str for floats and complex
193 numbers; the float and complex constructors; old-style and new-style
194 numeric formatting; serialization and deserialization of floats and
195 complex numbers using marshal, pickle and json; parsing of float and
196 imaginary literals in Python code; Decimal-to-float conversion.
197
198 The conversions use a Python-adapted version of David Gay's
199 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
200 functions. This code is supported on Windows, and on Unix-like
201 platforms using gcc, icc or suncc as the C compiler. There may be a
202 small number of platforms on which correct operation of this code
203 cannot be guaranteed, so the code is not used: notably, this applies
204 to platforms where the C double format is not IEEE 754 binary64, and
205 to platforms on x86 hardware where the x87 FPU is set to 64-bit
206 precision and Python's configure script is unable to determine how
207 to change the FPU precision. On these platforms conversions use the
208 platform strtod and dtoa, as before.
209
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000210- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000211 now uses the correctly-rounded string <-> float conversions
212 described above (when available), and so produces correctly rounded
213 results that will display nicely under the float repr. There are
214 two related small changes: (1) round now accepts any class with an
215 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000216 floats for the second argument), and (2) an excessively large second
217 integer argument (e.g., round(1.234, 10**100)) no longer raises an
218 exception.
219
Philip Jenveyfab8be22009-11-17 02:42:26 +0000220- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
221
Benjamin Petersone36199b2009-11-12 23:39:44 +0000222- Fix several issues with compile(). The input can now contain Windows and Mac
223 newlines and is no longer required to end in a newline.
224
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000225- Remove length limitation when constructing a complex number from a
226 unicode string.
227
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000228- Issue #7244: itertools.izip_longest() no longer ignores exceptions
229 raised during the formation of an output tuple.
230

232
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000233- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

235 interpreter is killed. Patch by Adam Olsen.
236
Eric Smithc12781a2009-10-19 14:38:14 +0000237- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

241 crash in GAE.
242
Benjamin Peterson196b0922009-10-15 15:44:46 +0000243- Issue #7140: The __dict__ of a module should not be cleared unless the module
244 is the only object holding a reference to it.
245
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000246- Issue #1754094: Improve the stack depth calculation in the compiler.
247 There should be no other effect than a small decrease in memory use.
248 Patch by Christopher Tur Lesniewski-Laas.
249
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000250- Issue #7084: Fix a (very unlikely) crash when printing a list from one
251 thread, and mutating it from another one. Patch by Scott Dial.
252
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000253- Issue #1571184: The Unicode database contains properties for more characters.

266 of producing internally inconsistent Python longs.
267
Philip Jenveydbf3b252009-09-29 04:32:44 +0000268- Issue #6990: Fix threading.local subclasses leaving old state around
269 after a reference cycle GC which could be recycled by new locals.
270
Benjamin Peterson9db55402009-09-18 21:47:27 +0000271- Issue #6300: unicode.encode, unicode.decode, str.decode, and str.encode now

311 functions and methods.
312
Mark Dickinson2f865b92009-06-30 15:32:30 +0000313- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
314 This fixes a build failure on HP-UX: int32_t and uint32_t are
315 defined in inttypes.h instead of stdint.h on that platform.

Raymond Hettinger62641e92009-06-23 20:59:43 +0000324- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
325 because it wasn't recognized as a sequence).
326
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +0000327- Issue #6289: Encoding errors from compile() were being masked.
328
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000329- When no module is given in a relative import, the module field of the
330 ImportFrom AST node is now None instead of an empty string.
331
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000332- Assignment to None using import statements now raises a SyntaxError.
333
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +0000334- Issue #4547: When debugging a very large function, it was not always
335 possible to update the lineno attribute of the current frame.
336
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000337- Issue #5330: C functions called with keyword arguments were not reported by
Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000338 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000339
Raymond Hettinger578a2282009-05-29 04:58:52 +0000340- Issue #5982: staticmethod and classmethod now expose the wrapped
341 function with __func__.
342
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000343- Added support for multiple context managers in the same with-statement.
344 Deprecated contextlib.nested() which is no longer needed.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000346- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
347 statement and correctly lookup the __enter__ and __exit__ special methods.
348
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000349- Issue #5829: complex("1e500") no longer raises OverflowError. This
350 makes it consistent with float("1e500") and interpretation of real
351 and imaginary literals.
352
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000353- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
354
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000355- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
356 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000357
R. David Murray525cffc2009-05-13 13:07:14 +0000358- Issue #5994: the marshal module now has docstrings.
359
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000360- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
361 (1) inf and nan strings with trailing whitespace were incorrectly
362 rejected; (2) parsing of strings representing infinities and nans
363 was locale aware; and (3) the interpretation of fromhex('-nan')
364 didn't match that of float('-nan').
365
Eric Smitha985a3a2009-05-05 18:26:08 +0000366- Issue #5920: For float.__format__, change the behavior with the
367 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
368 to be like 'g' but with at least one decimal point and with a
369 default precision of 12. Previously, the behavior the same but with
370 a default precision of 6. This more closely matches str(), and
371 reduces surprises when adding alignment flags to the empty
372 presentation type. This also affects the new complex.__format__ in
373 the same way.
374
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000375- Issue #5890: in subclasses of 'property' the __doc__ attribute was
376 shadowed by classtype's, even if it was None. property now
377 inserts the __doc__ into the subclass instance __dict__.
378
Antoine Pitrou653dece2009-05-04 18:32:32 +0000379- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

392 titlecase, but not their own uppercase.
393
Eric Smith068f0652009-04-25 21:40:15 +0000394- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
395 _PyOS_double_to_string or PyOS_double_to_string.
396

398
Mark Dickinson95bc9802009-04-24 12:46:53 +0000399- Issue #5816: complex(repr(z)) now recovers z exactly, even when
400 z involves nans, infs or negative zeros.
401
Eric Smithaca19e62009-04-22 13:29:05 +0000402- Implement PEP 378, Format Specifier for Thousands Separator, for
403 floats, ints, and longs.
404
405- Issue #5515: 'n' formatting for ints, longs, and floats handles
406 leading zero formatting poorly.
407
408- Issue #5772: For float.__format__, don't add a trailing ".0" if
409 we're using no type code and we have an exponent.
410
Mark Dickinson6736cf82009-04-20 21:13:33 +0000411- Issue #3166: Make long -> float (and int -> float) conversions
412 correctly rounded.
413

415 some builtin types.
416
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000417- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000418 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000419
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000420- Issue #5759: float() didn't call __float__ on str subclasses.
421
Georg Brandl3c4a5462009-04-12 12:08:12 +0000422- Issue #5704: the "-3" command-line option now implies "-t".
423
R. David Murray0374a822009-04-09 21:54:50 +0000424- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
425 its clarity and its speed.
426

Ronald Oussorene0154ed2009-03-30 23:10:35 +0000434- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
435 the end sys.path, for compatibility with the system install of Python.
436
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000437- Issue #4688: Add a heuristic so that tuples and dicts containing only
438 untrackable objects are not tracked by the garbage collector. This can
439 reduce the size of collections and therefore the garbage collection overhead
440 on long-running programs, depending on their particular use of datatypes.
441
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000442- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
443 improve its performance. Long divisions and remainder operations
444 are now between 50% and 150% faster.
445
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000446- Issue #4258: Make it possible to use base 2**30 instead of base
447 2**15 for the internal representation of integers, for performance
448 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
449 --enable-big-digits option to configure, which overrides the
450 default. Add sys.long_info structseq to provide information about
451 the internal format.
452
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000453- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
454 result traceback.__members__ no longer exists.)
455
Mark Dickinson6b265f12009-03-18 16:07:26 +0000456- Issue #4474: PyUnicode_FromWideChar now converts characters outside
457 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
458 and sizeof(Py_UNICODE) == 2.
459
Eric Smith6f42edb2009-03-14 11:57:26 +0000460- Issue #5237: Allow auto-numbered fields in str.format(). For
461 example: '{} {}'.format(1, 2) == '1 2'.
462
Brett Cannon6c4cff02009-03-11 04:51:06 +0000463- Issue #3652: Make the 'line' argument for warnings.showwarning() a
464 requirement. Means the DeprecationWarning from Python 2.6 can go away.
465
Eric Smithe9fb6862009-02-20 14:02:36 +0000466- Issue #5247: Improve error message when unknown format codes are
467 used when using str.format() with str, unicode, long, int, and
468 float arguments.
469
Raymond Hettinger08259e82009-02-18 23:10:19 +0000470- Running Python with the -3 option now also warns about classic division
471 for ints and longs.
472
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000473- Issue #5260: Long integers now consume less memory: average
474 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
475 on a 64-bit system.
476
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000477- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
478 rotating the object pointer by 4 bits to the right.
479
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000480- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
481 it now forces its argument to double before testing for infinity.
482
Benjamin Petersone18ef192009-01-20 14:21:16 +0000483- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
484
Georg Brandl29c6a282009-04-05 20:23:13 +0000485- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000486 were suppressing all exceptions. These include list(), filter(), map(),
487 zip(), and bytearray().
488
Benjamin Peterson596d3062009-01-19 15:42:23 +0000489- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
490 functions.
491
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000492- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

496
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000497- Issue #4935: The overflow checking code in the expandtabs() method common
498 to str, bytes and bytearray could be optimized away by the compiler, letting
499 the interpreter segfault instead of raising an error.

507
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000508- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
509 collecting the oldest generation) so that allocating lots of objects without
510 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000511 Martin von Löwis at

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000516- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
517 an existing .py counterpart, override the co_filename attributes of all
518 code objects if the original filename is obsolete (which can happen if the
519 file has been renamed, moved, or if it is accessed through different paths).
520 Patch by Ziga Seilnacht and Jean-Paul Calderone.

531 where the tp_hash and tp_dict slots are both NULL.
532
Benjamin Peterson7af65562008-12-29 17:56:58 +0000533- Issue #4764: With io.open, IOError.filename is set when trying to open a

543 fail.
544
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000545- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
546 print elapsed times, not only when some objects are uncollectable /

559
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000560- Issue #4445: Replace "sizeof(PyStringObject)" with
561 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
562 str instances. On a typical machine this saves 3 bytes of memory
563 (on average) per string allocation.
564
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000565- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000576 method on file objects with closefd=False. The file descriptor is still
577 kept open but the file object behaves like a closed file. The ``FileIO``
578 object also got a new readonly attribute ``closefd``.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000601- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
602 returned a path longer than MAX_PATH. (But It's doubtful this code path is
603 really executed because I cannot move to such directory on win2k)

Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000605- Issue #4069: When set.remove(element) is used with a set element, the element
606 is temporarily replaced with an equivalent frozenset. But the eventual
607 KeyError would always report the empty frozenset([]) as the missing key. Now
608 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000628- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
629 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
630 step. This avoids problems with counting UTF-8 bytes that ignores the effect
631 of using the replace error handler in PyUnicode_DecodeUTF8().
632
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000633- Issue #3739: The unicode-internal encoder now reports the number of characters

635
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000636- Issue #2422: When compiled with the ``--with-valgrind`` option, the
637 pymalloc allocator will be automatically disabled when running under
638 Valgrind. This gives improved memory leak detection when running
639 under Valgrind, while taking advantage of pymalloc at other times.

709 to execute file paths that refer to source or compiled Python files as well
710 as zipfiles, directories and other valid sys.path entries that contain a

2018
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002019- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2020
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002021- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2022 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2023 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2024 ``printf`` function, whereas PyString_FromFormat has an independent
2025 implementation and uses "%zd" on all platforms for size_t values.
2026 This makes a difference on win64, where ``printf`` needs "%Id" to display
2027 64bit values.
2028
Benjamin Peterson97179b02008-09-09 20:55:01 +00002029- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2030 error.
2031
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002032- Issue #3777: long() applied to a float object now always return a long
2033 object; previously an int would be returned for small values. the __long__
2034 method is allowed to return either an int or a long, but the behaviour of
2035 float objects should not change to respect backward compatibility.
2036
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002037- Issue #3751: str.rpartition would perform a left-partition when called with
2038 a unicode argument.
2039
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002040- Issue #3683: Fix compilation when --without-threads is given.
2041
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002042- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002043 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002044 was correctly parsed but parsing of subsequent arguments failed.
2045
Vinay Sajip35e3b032008-09-01 14:33:59 +00002046- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002047 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2048 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2049 when given a tuple of classes as second argument, were looking up
2050 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2051 type object.
2052
Neal Norwitz18aa3882008-08-24 05:04:52 +00002053- Fix crashes on memory allocation failure found with failmalloc.
2054
2055- Fix memory leaks found with valgrind and update suppressions file.
2056
2057- Fix compiler warnings in opt mode which would lead to invalid memory reads.

2122 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2123 for catch_warnings() also led to an improvement in the raising of a
2124 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002194
2195Core and Builtins
2196-----------------
2197
Guido van Rossumf8402962008-08-20 15:01:50 +00002198- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2199 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2200 extensions do not automatically benefit from the class attribute
2201 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2202 to their tp_flags field if they care. This is a backwards
2203 compatibility feature; in 3.0, all types will use the cache by
2204 default.
2205
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002206- Keyword arguments can now follow starred arguments. (``f(a, *args,
2207 keyword=23)`` is now valid syntax.)
2208
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002209- ctypes function pointers that are COM methods have a boolean True
2210 value again.
2211
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002212- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2213 by denying s# to parse objects that have a releasebuffer procedure,
2214 and introducing s*.
2215
Georg Brandl1e13ea92008-08-11 09:07:59 +00002216- Issue #3537: Fix an assertion failure when an empty but presized dict
2217 object was stored in the freelist.
2218
Mark Dickinsonb6467572008-08-04 21:30:09 +00002219- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2220 ValueError consistently across platforms.
2221
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002222- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2223 (64bit Unix, for example), unichr() would truncate its argument and return
2224 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2225
Neal Norwitze7d8be82008-07-31 17:17:14 +00002226- Apply security patches from Apple.
2227
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002228- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2229 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2230
Antoine Pitrou92f82162008-07-25 22:22:08 +00002231- Issue #1819: function calls with several named parameters are now on
2232 average 35% faster (as measured by pybench).
2233
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002234- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2235 the python debugger steps into a class statement: the free variables (local
2236 variables defined in an outer scope) would be deleted from the outer scope.
2237
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002238- Issue #2620: Overflow checking when allocating or reallocating memory
2239 was not always being done properly in some python types and extension
2240 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2241 all been updated to perform better checks and places in the code that
2242 would previously leak memory on the error path when such an allocation
2243 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002248- Issue #3612: Added some missing basic types in ctypes.wintypes.
2249
Benjamin Petersone977ad42008-08-20 01:42:01 +00002250- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2251 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2252
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002253- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2254 version reported by these tools does not necessarily follow the python
2255 version numbering scheme, so the module is less strict when parsing it.
2256
Nick Coghlanf70385a2008-08-18 12:42:46 +00002257- Issue #2235: Added Py3k warnings for types which will become unhashable
2258 under the stricter __hash__ inheritance rules in 3.0. Several types
2259 which did not meet the rules for hash invariants and were already
2260 unhashable in 3.0 have now been explicitly flagged as unhashable in
2261 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2262 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2263
Brett Cannon88f801d2008-08-18 00:46:22 +00002264- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2265 imported into the module but exposed as part of the module's API.
2266
Brett Cannon7b96f072008-08-18 00:41:11 +00002267- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2268

2377
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002378- Issue #643841: The language reference now provides more detailed

2390-----------------
2391
Georg Brandl3e483f62008-07-16 22:57:41 +00002392- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2393 its methods now allow for items objects that can be converted to
2394 an integer using operator.index().
2395
Mark Dickinson64b7e502008-07-16 09:40:03 +00002396- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2397 produced a ValueError instead of giving the correct float.
2398
Eric Smitha5fa5a22008-07-16 00:11:49 +00002399- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2400 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2401
Mark Dickinson7103aa42008-07-15 19:08:33 +00002402- Issue #3008: the float type has a new instance method 'float.hex'
2403 and a new class method 'float.fromhex' to convert floating-point
2404 numbers to and from hexadecimal strings, respectively.
2405
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002406- Issue #2235: __hash__ is once again inherited by default. To allow
2407 collections.Hashable to remain meaningful in the presence of the
2408 default hash implementation (object.__hash__), it is now possible
2409 to explicit block inheritance of hash by setting __hash__=None at
2410 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2411 level.
2412
Nick Coghlanb028f502008-07-13 14:52:36 +00002413- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2414 the parent module cannot be found while performing an absolute import.
2415 This means that an incorrectly defined __package__ attribute will
2416 now only prevent relative imports in that module rather than causing
2417 all imports from that module to fail.
2418
Nick Coghlan14ff9942008-07-08 14:21:42 +00002419- Issue #2517: Allow unicode messages in Exceptions again by correctly
2420 bypassing the instance dictionary when looking up __unicode__ on
2421 new-style classes.

2424 set to a custom object whose write() method happens to install
2425 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002427- Issue #3088: Corrected a race condition in classes derived from
2428 threading.local: the first member set by a thread could be saved in
2429 another thread's dictionary.
2430
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002431- Issue #3004: Minor change to slice.indices(): the start and stop
2432 arguments are now treated identically, making the behaviour easier
2433 to describe and understand. For example, slice(None, -10,
2434 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2435 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2436 10, -1).
2437
Georg Brandl278fc502008-07-19 12:46:12 +00002438- Issue #3219: Calling a function with repeated keyword arguments,
2439 f(a=2, a=23), would not cause a syntax error. This was a regression
2440 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002441
Georg Brandl278fc502008-07-19 12:46:12 +00002442- Issue #2862: Make int and float freelist management consistent with
2443 other freelists. Changes their CompactFreeList apis into

2450 api functions without holding the GIL, which could lead to a fatal
2451 error when they failed.
2452
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002453- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002478- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2479 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002480 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002481 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002497- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2840 large to fit in a C long. ldexp(x, n) now returns a zero (with
2841 suitable sign) if n is large and negative; previously, it raised

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002888- On MacOS X it is now possible to install the framework in 64-bit
2889 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002890 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002891
2892 This is controlled by the configure argument ``--with-universal-archs``:
2893
2894 - ``--with-universal-archs=all``: install 4-way universal
2895
2896 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2897
2898 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2899
2900 This option should be used in combination with ``--enable-universalsdk=``.
2901
2902 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 +00002952- Issue #1631171: Re-implement the 'warnings' module in C (the
2953 original Python code has been kept as backup). This will allow for
2954 using the 'warning's machinery in such places as the parser where
2955 use of pure Python code is not possible. Both the ``showarning()``
2956 and ``formatwarning()`` gain an optional 'line' argument which is
2957 not called by default for backwards-compatibility reasons. Setting
2958 ``warnings.showwarning()`` to an implementation that lacks support
2959 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003022- Issue #2550: The approach used by client/server code for obtaining
3023 ports to listen on in network-oriented tests has been refined in an
3024 effort to facilitate running multiple instances of the entire
3025 regression test suite in parallel without issue.
3026 test_support.bind_port() has been fixed such that it will always
3027 return a unique port -- which wasn't always the case with the
3028 previous implementation, especially if socket options had been set
3029 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3030 new implementation of bind_port() will actually raise an exception
3031 if it is passed an AF_INET/SOCK_STREAM socket with either the
3032 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3033 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3034 the socket it's been passed. This currently only applies to
3035 Windows. This option prevents any other sockets from binding to the
3036 host/port we've bound to, thus removing the possibility of the
3037 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3038 when a second SOCK_STREAM socket binds and accepts to a host/port
3039 that's already been bound by another socket. The optional preferred
3040 port parameter to bind_port() has been removed. Under no
3041 circumstances should tests be hard coding ports!
3042
3043 test_support.find_unused_port() has also been introduced, which will
3044 pass a temporary socket object to bind_port() in order to obtain an
3045 unused port. The temporary socket object is then closed and
3046 deleted, and the port is returned. This method should only be used
3047 for obtaining an unused port in order to pass to an external program
3048 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3049 a parameter to a server-oriented class that doesn't give you direct
3050 access to the underlying socket used.
3051
3052 Finally, test_support.HOST has been introduced, which should be used
3053 for the host argument of any relevant socket calls (i.e. bind and
3054 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003055
3056 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003058 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3059 test_asynchat and test_socket_ssl.
3060
Georg Brandl3ee81df2008-05-17 18:14:43 +00003061 It is now possible for multiple instances of the regression test
3062 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003116- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003117 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3118 Plane. This affected raw unicode literals and the
3119 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3120 this case, like normal unicode literals and the 'unicode-escape'
3121 codec.

3329-----------------
3330
Fred Drakea8ee94b2008-03-01 02:45:07 +00003331- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003332 644. The mode is now inherited from the py file.

3335
3336- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003337
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003338- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003339 issue 215555 for a discussion.
3340
Eric Smitha73fbe72008-02-23 03:09:44 +00003341- Added the future_builtins module, which contains hex() and oct().
3342 These are the PEP 3127 version of these functions, designed to be
3343 compatible with the hex() and oct() builtins from Python 3.0. They
3344 differ slightly in their output formats from the existing, unchanged
3345 Python 2.6 builtins. The expected usage of the future_builtins
3346 module is:
3347 from future_builtins import hex, oct
3348
Eric Smith7ef40bf2008-02-20 23:34:22 +00003349- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3350 exponents for exponents with absolute value < 100. Follows C99
3351 standard. This is a change on Windows, which would use 3 digits.
3352 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3353 so that any alterations it does to the resulting string will be
3354 available in stringlib/formatter.h (for float.__format__).
3355
Eric Smith5a3c1352008-02-19 13:21:56 +00003356- Implemented PEP 3101, Advanced String Formatting. This adds a new
3357 builtin format(); a format() method for str and unicode; a
3358 __format__() method to object, str, unicode, int, long, float, and
3359 datetime; the class string.Formatter; and the C API
3360 PyObject_Format().
3361
Georg Brandl3ee81df2008-05-17 18:14:43 +00003362- Fixed several potential crashes, all caused by specially crafted
3363 __del__ methods exploiting objects in temporarily inconsistent
3364 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003365
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003366- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003367 prevent a possible crash: an Abstract Base Class would try to access
3368 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003369

Georg Brandl3ee81df2008-05-17 18:14:43 +00003373- Clear all free lists during a gc.collect() of the highest generation
3374 in order to allow pymalloc to free more arenas. Python may give back
3375 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003376
Georg Brandl3ee81df2008-05-17 18:14:43 +00003377- Issue #2045: Fix an infinite recursion triggered when printing a
3378 subclass of collections.defaultdict, if its default_factory is set

Christian Heimesf75dbef2008-02-08 00:11:31 +00003381- Fixed a minor memory leak in dictobject.c. The content of the free
3382 list was not freed on interpreter shutdown.
3383
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- Limit free list of method and builtin function objects to 256
3385 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3388 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003389 to compact the internal free lists of pre-allocted ints and floats.
3390
Georg Brandl3ee81df2008-05-17 18:14:43 +00003391- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3392 calls. Python expected the return type int but the fork familie
3393 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003394
Georg Brandl3ee81df2008-05-17 18:14:43 +00003395- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3396 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003407- Patch #1473257: generator objects gain a gi_code attribute. This is
3408 the same object as the func_code attribute of the function that
3409 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003410
Georg Brandl3ee81df2008-05-17 18:14:43 +00003411- Issue #1920: "while 0" statements were completely removed by the
3412 compiler, even in the presence of an "else" clause, which is
3413 supposed to be run when the condition is false. Now the compiler
3414 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003415
Guido van Rossumeead05f2008-01-24 18:21:02 +00003416- A few crashers fixed: weakref_in_del.py (issue #1377858);
3417 loosing_dict_ref.py (issue #1303614, test67.py);
3418 borrowed_ref_[34].py (not in tracker).
3419
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003420- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003421 suppressed while an extension is loaded by calling SetErrorMode in
3422 dynload_win.c. The error is still reported properly.
3423
Georg Brandl3ee81df2008-05-17 18:14:43 +00003424- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003425 several extension methods and modules do not work without unicode
3426 support.
3427
Georg Brandl26543b12008-01-21 18:36:51 +00003428- Issue #1882: when compiling code from a string, encoding cookies in the
3429 second line of code were not always recognized correctly.
3430
Georg Brandl14404b62008-01-19 19:27:05 +00003431- Issue #1679: "0x" was taken as a valid integer literal.
3432
Georg Brandl6caad7d2008-01-26 14:19:22 +00003433- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003434 added.
3435
Christian Heimesc94e2b52008-01-14 04:13:37 +00003436- sys.float_info / PyFloat_GetInfo: The floating point information
3437 object was converted from a dict to a specialized structseq object.
3438
Georg Brandl3ee81df2008-05-17 18:14:43 +00003439- Patch #1816: Added sys.flags structseq. It exposes the status of
3440 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003441
Georg Brandl3ee81df2008-05-17 18:14:43 +00003442- Objects/structseq.c: Implemented new structseq representation. The
3443 patch makes structseqs (e.g. the return value of os.stat) more
3444 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003445
Georg Brandl3ee81df2008-05-17 18:14:43 +00003446- Patch #1700288: added a type attribute cache that caches method
3447 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003448
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003449- Bug #1776: __import__() no longer accepts filenames on any platform.
3450 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003451

3455 envvar and sys.dont_write_bytecode attribute. All these can be set
3456 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003457
Georg Brandl3ee81df2008-05-17 18:14:43 +00003458- Improve some exception messages when Windows fails to load an
3459 extension module. Now we get for example '%1 is not a valid Win32
3460 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003461

Christian Heimes0a8143f2007-12-18 23:22:54 +00003467- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003468 and INF. float("nan"), float("inf") and float("-inf") now work on
3469 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003470
Georg Brandl3ee81df2008-05-17 18:14:43 +00003471- Compiler now generates simpler and faster code for dictionary
3472 literals. The oparg for BUILD_MAP now indicates an estimated
3473 dictionary size. There is a new opcode, STORE_MAP, for adding
3474 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003503- Patch #1739468: Directories and zipfiles containing a __main__.py
3504 file can now be directly executed by passing their name to the
3505 interpreter. The directory/zipfile is automatically inserted as the
3506 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003507
Georg Brandl3ee81df2008-05-17 18:14:43 +00003508- Issue #1265: Fix a problem with sys.settrace, if the tracing
3509 function uses a generator expression when at the same time the
3510 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003511
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003512- sets and frozensets now have an isdisjoint() method.
3513

3515
Neal Norwitz44f326e2007-10-05 05:29:17 +00003516- Fix warnings found by the new version of the Coverity checker.
3517
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518- The enumerate() builtin function is no longer bounded to sequences
3519 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3520 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003521
Georg Brandl3ee81df2008-05-17 18:14:43 +00003522- Issue #1686386: Tuple's tp_repr did not take into account the
3523 possibility of having a self-referential tuple, which is possible
3524 from C code. Nor did object's tp_str consider that a type's tp_str
3525 could do something that could lead to an inifinite recursion.
3526 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3527 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003528
Georg Brandl3ee81df2008-05-17 18:14:43 +00003529- Issue #1164: It was possible to trigger deadlock when using the
3530 'print' statement to write to a file since the GIL was not released
3531 as needed. Now PyObject_Print() does the right thing along with
3532 various tp_print implementations of the built-in types and those in
3533 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003534
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Issue #1147: Exceptions were directly allowing string exceptions in
3536 their throw() method even though string exceptions no longer
3537 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003538
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003542- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003543 PyObject_Call() never calling back out to Python code to trigger
3544 recursion depth updates/checks. Required the creation of a static
3545 RuntimeError instance in case normalizing an exception put the
3546 recursion check value past its limit. Fixes crashers
3547 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003548

Neal Norwitz0ac60192007-05-27 04:08:54 +00003562- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003563 __*__ attributes. (Some already existed, e.g., __doc__ and
3564 __name__.)

3570 calls.
3571
Collin Winter62903052007-05-18 23:11:24 +00003572- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003573 "except E as target:". This is to provide forwards compatibility
3574 with Python 3.0.

3580
Vinay Sajip8549ce32007-05-06 17:53:37 +00003581- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003582 setting a plain string, ie don't expand to single letter identifiers.
3583
Raymond Hettinger13936692007-04-11 18:40:58 +00003584- Request #1191699: Slices can now be pickled.
3585
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003586- Request #1193128: str.translate() now allows a None argument for

3588 remaining characters.
3589
Georg Brandl5cb76c12007-03-21 09:00:39 +00003590- Patch #1682205: a TypeError while unpacking an iterable is no longer
3591 masked by a generic one with the message "unpack non-sequence".
3592
Neal Norwitzaa754b72007-03-21 06:39:48 +00003593- Remove unused file Python/fmod.c.
3594
Guido van Rossum143b5642007-03-23 04:58:42 +00003595- Bug #1683368: The object.__init__() and object.__new__() methods are
3596 now stricter in rejecting excess arguments. The only time when
3597 either allows excess arguments is when it is not overridden and the
3598 other one is. For backwards compatibility, when both are
3599 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003600 warning later). Also, type.__init__() insists on the same signature
3601 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003603- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3604 object to complex using its __complex__() method before falling back
3605 to the __float__() method. Therefore, the functions in the cmath
3606 module now can operate on objects that define a __complex__()
3607 method.

3617 ``object.__reduce_ex__()`` is called with an object that is faking
3618 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003619
Georg Brandl3ee81df2008-05-17 18:14:43 +00003620- Patch #1680015: Don't modify __slots__ tuple if it contains an

3626 case, even when converting the value to a string failed.
3627
Georg Brandl871f1bc2007-03-12 13:17:36 +00003628- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003629 its argument, if it exists. If not, it will work like before. This
3630 allows customizing the output of dir() in the presence of a
3631 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003632
Collin Winter276887b2007-03-12 16:11:39 +00003633- Patch #922167: Python no longer segfaults when faced with infinitely
3634 self-recursive reload() calls (as reported by bug #742342).

Georg Brandlaa2321b2007-03-07 00:40:28 +00003643- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003644 makes the filenames the warning module prints much more sensible
3645 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003658- Patch #1674228: when assigning a slice (old-style), check for the
3659 sq_ass_slice instead of the sq_slice slot.
3660
Georg Brandl3ee81df2008-05-17 18:14:43 +00003661- When printing an unraisable error, don't print exceptions. before
3662 the name. This duplicates the behavior whening normally printing
3663 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003671- Bug #1377858: Fix the segfaulting of the interpreter when an object
3672 created a weakref on itself during a __del__ call for new-style
3673 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00003713- Bug #1545497: when given an explicit base, int() did ignore NULs
3714 embedded in the string to convert.
3715
Georg Brandl846f73a2006-10-08 07:11:54 +00003716- Bug #1569998: break inside a try statement (outside a loop) is now
3717 recognized and rejected.
3718

3720
Armin Rigo7ccbca92006-10-04 12:17:45 +00003721- A number of places, including integer negation and absolute value,
3722 were fixed to not rely on undefined behaviour of the C compiler
3723 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00003724

Georg Brandl4e933132006-09-06 20:05:58 +00003746- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003764 generator expressions (x for x, in ... ) works again. Fixing this
3765 problem required changing the .pyc magic number. This means that
3766 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00003805- Removed uses of dict.has_key() from distutils, and uses of
3806 callable() from copy_reg.py, so the interpreter now starts up

4575 obtained from the TLS negotiation itself. Patch contributed by Bill
4576 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004578- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004579 that the SMTP.starttls() caller no longer needs to call ehlo()
4580 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004581 does not claim to support starttls. Adds the
4582 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4583 Fenner.

4663 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4664 silently miscode subclasses of those types. Now, it raises a
4665 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004666

Georg Brandl3ee81df2008-05-17 18:14:43 +00004681 time so that opening a database previously created with the DB_DUP
4682 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4683 opens. Specifically: dictionary assignment to a DB object will
4684 replace all values for a given key when the database allows
4685 duplicate values. DB users should use DB.put(k, v) when they want
4686 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004687

4693 characters with ASCII value less than 32. Also, it correctly quotes
4694 dots only if they occur on a single line, as opposed to the previous
4695 behavior of quoting dots if they are the second character of any
4696 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004697
