Barry Warsaw12582c92008-10-02 03:33:51 +00007What's New in Python 2.7 alpha 1
8================================
9
10*Release date: XX-XXX-20XX*
11
12Core and Builtins
13-----------------
14
Mark Dickinson9dd5e162009-11-23 20:54:09 +000015- Remove switch from "%f" formatting to "%g" formatting for floats
16 larger than 1e50 in absolute value.
17
Mark Dickinson18cfada2009-11-23 18:46:41 +000018- Remove restrictions on precision when formatting floats. E.g.,
19 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
20 requested 120 significant digits instead.
21
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000022- Add Py3k warnings for parameter names in parenthesis.
23
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000024- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000025
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000026- Issue #7085: Fix crash when importing some extensions in a thread
27 on MacOSX 10.6.
28
Mark Dickinsonb678de82009-11-19 18:41:49 +000029- Issue #7117: repr(x) for a float x returns a result based on the
30 shortest decimal string that's guaranteed to round back to x under
31 correct rounding (with round-half-to-even rounding mode).
32 Previously it gave a string based on rounding x to 17 decimal digits.
33 repr(x) for a complex number behaves similarly. On platforms where
34 the correctly-rounded strtod and dtoa code is not supported (see below),
35 repr is unchanged.
36
37- Issue #7117: On almost all platforms: float-to-string and
38 string-to-float conversions within Python are now correctly rounded.
39 Places these conversions occur include: str for floats and complex
40 numbers; the float and complex constructors; old-style and new-style
41 numeric formatting; serialization and deserialization of floats and
42 complex numbers using marshal, pickle and json; parsing of float and
43 imaginary literals in Python code; Decimal-to-float conversion.
44
45 The conversions use a Python-adapted version of David Gay's
46 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
47 functions. This code is supported on Windows, and on Unix-like
48 platforms using gcc, icc or suncc as the C compiler. There may be a
49 small number of platforms on which correct operation of this code
50 cannot be guaranteed, so the code is not used: notably, this applies
51 to platforms where the C double format is not IEEE 754 binary64, and
52 to platforms on x86 hardware where the x87 FPU is set to 64-bit
53 precision and Python's configure script is unable to determine how
54 to change the FPU precision. On these platforms conversions use the
55 platform strtod and dtoa, as before.
56
Mark Dickinsonbd15a062009-11-18 19:33:35 +000057- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +000058 now uses the correctly-rounded string <-> float conversions
59 described above (when available), and so produces correctly rounded
60 results that will display nicely under the float repr. There are
61 two related small changes: (1) round now accepts any class with an
62 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +000063 floats for the second argument), and (2) an excessively large second
64 integer argument (e.g., round(1.234, 10**100)) no longer raises an
65 exception.
66
Philip Jenveyfab8be22009-11-17 02:42:26 +000067- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
68
Benjamin Petersone36199b2009-11-12 23:39:44 +000069- Fix several issues with compile(). The input can now contain Windows and Mac
70 newlines and is no longer required to end in a newline.
71

73 unicode string.
74
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +000075- Issue #7244: itertools.izip_longest() no longer ignores exceptions
76 raised during the formation of an output tuple.
77

82 interpreter is killed. Patch by Adam Olsen.
83
Eric Smithc12781a2009-10-19 14:38:14 +000084- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000193- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
194 statement and correctly lookup the __enter__ and __exit__ special methods.
195
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000196- Issue #5829: complex("1e500") no longer raises OverflowError. This
197 makes it consistent with float("1e500") and interpretation of real
198 and imaginary literals.
199
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000200- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

206
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000207- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
208 (1) inf and nan strings with trailing whitespace were incorrectly
209 rejected; (2) parsing of strings representing infinities and nans
210 was locale aware; and (3) the interpretation of fromhex('-nan')
211 didn't match that of float('-nan').
212
Eric Smitha985a3a2009-05-05 18:26:08 +0000213- Issue #5920: For float.__format__, change the behavior with the
214 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
215 to be like 'g' but with at least one decimal point and with a
216 default precision of 12. Previously, the behavior the same but with
217 a default precision of 6. This more closely matches str(), and
218 reduces surprises when adding alignment flags to the empty
219 presentation type. This also affects the new complex.__format__ in
220 the same way.
221
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000222- Issue #5890: in subclasses of 'property' the __doc__ attribute was
223 shadowed by classtype's, even if it was None. property now
224 inserts the __doc__ into the subclass instance __dict__.
225
Antoine Pitrou653dece2009-05-04 18:32:32 +0000226- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

239 titlecase, but not their own uppercase.
240
Eric Smith068f0652009-04-25 21:40:15 +0000241- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with

243
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000244- Issue #5283: Setting __class__ in __del__ caused a segfault.
245
Mark Dickinson95bc9802009-04-24 12:46:53 +0000246- Issue #5816: complex(repr(z)) now recovers z exactly, even when
247 z involves nans, infs or negative zeros.
248
Eric Smithaca19e62009-04-22 13:29:05 +0000249- Implement PEP 378, Format Specifier for Thousands Separator, for
250 floats, ints, and longs.
251
252- Issue #5515: 'n' formatting for ints, longs, and floats handles
253 leading zero formatting poorly.
254
255- Issue #5772: For float.__format__, don't add a trailing ".0" if
256 we're using no type code and we have an exponent.
257

263
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000264- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000265 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000266
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000267- Issue #5759: float() didn't call __float__ on str subclasses.
268
Georg Brandl3c4a5462009-04-12 12:08:12 +0000269- Issue #5704: the "-3" command-line option now implies "-t".

283
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000284- Issue #4688: Add a heuristic so that tuples and dicts containing only
285 untrackable objects are not tracked by the garbage collector. This can
286 reduce the size of collections and therefore the garbage collection overhead
287 on long-running programs, depending on their particular use of datatypes.
288
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000289- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
290 improve its performance. Long divisions and remainder operations
291 are now between 50% and 150% faster.
292
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000293- Issue #4258: Make it possible to use base 2**30 instead of base
294 2**15 for the internal representation of integers, for performance
295 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
296 --enable-big-digits option to configure, which overrides the
297 default. Add sys.long_info structseq to provide information about
298 the internal format.
299
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000300- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
301 result traceback.__members__ no longer exists.)
302
Mark Dickinson6b265f12009-03-18 16:07:26 +0000303- Issue #4474: PyUnicode_FromWideChar now converts characters outside
304 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
305 and sizeof(Py_UNICODE) == 2.
306
Eric Smith6f42edb2009-03-14 11:57:26 +0000307- Issue #5237: Allow auto-numbered fields in str.format(). For
308 example: '{} {}'.format(1, 2) == '1 2'.
309
Brett Cannon6c4cff02009-03-11 04:51:06 +0000310- Issue #3652: Make the 'line' argument for warnings.showwarning() a
311 requirement. Means the DeprecationWarning from Python 2.6 can go away.
312
Eric Smithe9fb6862009-02-20 14:02:36 +0000313- Issue #5247: Improve error message when unknown format codes are
314 used when using str.format() with str, unicode, long, int, and
315 float arguments.
316
Raymond Hettinger08259e82009-02-18 23:10:19 +0000317- Running Python with the -3 option now also warns about classic division
318 for ints and longs.
319
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000320- Issue #5260: Long integers now consume less memory: average
321 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
322 on a 64-bit system.
323
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000324- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
325 rotating the object pointer by 4 bits to the right.
326
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000327- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
328 it now forces its argument to double before testing for infinity.
329
Benjamin Petersone18ef192009-01-20 14:21:16 +0000330- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
331
Georg Brandl29c6a282009-04-05 20:23:13 +0000332- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000333 were suppressing all exceptions. These include list(), filter(), map(),
334 zip(), and bytearray().
335
Benjamin Peterson596d3062009-01-19 15:42:23 +0000336- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
337 functions.
338
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000339- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

343
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000344- Issue #4935: The overflow checking code in the expandtabs() method common
345 to str, bytes and bytearray could be optimized away by the compiler, letting
346 the interpreter segfault instead of raising an error.
347
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000348- Issue #3720: Fix a crash when an iterator modifies its class and removes its

354
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000355- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
356 collecting the oldest generation) so that allocating lots of objects without
357 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000358 Martin von Löwis at

362
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000363- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
364 an existing .py counterpart, override the co_filename attributes of all
365 code objects if the original filename is obsolete (which can happen if the
366 file has been renamed, moved, or if it is accessed through different paths).
367 Patch by Ziga Seilnacht and Jean-Paul Calderone.
368
Martin v. Löwis5344c992009-01-02 20:32:55 +0000369- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000371- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
372 file with `str' filename on Windows.
373
Antoine Pitrouaa687902009-01-01 14:11:22 +0000374- Issue #3680: Reference cycles created through a dict, set or deque iterator
375 did not get collected.
376
Nick Coghlan180e4002008-12-30 01:18:48 +0000377- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
378 where the tp_hash and tp_dict slots are both NULL.
379
Benjamin Peterson7af65562008-12-29 17:56:58 +0000380- Issue #4764: With io.open, IOError.filename is set when trying to open a
381 directory on POSIX systems.
382
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000383- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
384 systems.
385
Georg Brandl6425a2f2008-12-28 11:54:53 +0000386- Issue #4759: None is now allowed as the first argument of
387 bytearray.translate(). It was always allowed for bytes.translate().
388
Skip Montanarof205c132008-12-23 03:30:15 +0000389- Added test case to ensure attempts to read from a file opened for writing
390 fail.
391
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000392- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

394 unreachable. Original patch by Neil Schemenauer.
395

402 context manager returns a value that cannot be converted to a bool.
403
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000404- Issue #4597: Fixed several opcodes that weren't always propagating
405 exceptions.
406
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000407- Issue #4445: Replace "sizeof(PyStringObject)" with
408 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
409 str instances. On a typical machine this saves 3 bytes of memory
410 (on average) per string allocation.
411
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000412- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
413 interpreter to abort ("Fatal Python error: Could not reset the stack!")
414 instead of throwing a MemoryError.
415
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000416- Issue #3689: The list reversed iterator now supports __length_hint__
417 instead of __len__. Behavior now matches other reversed iterators.
418
Benjamin Petersonc078f922008-11-21 22:27:24 +0000419- Issue #4367: Python would segfault during compiling when the unicodedata
420 module couldn't be imported and \N escapes were present.
421
Vinay Sajip213faca2008-12-03 23:22:58 +0000422- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000423 method on file objects with closefd=False. The file descriptor is still
424 kept open but the file object behaves like a closed file. The ``FileIO``
425 object also got a new readonly attribute ``closefd``.
426
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000427- Issue #4348: Some bytearray methods returned that didn't cause any change to
428 the bytearray, returned the same bytearray instead of a copy.
429
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000430- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
431
Benjamin Peterson273c2332008-11-17 22:39:09 +0000432- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
433
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000434- Issue #4048: The parser module now correctly validates relative imports.
435
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000436- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
437 exec statement.
438
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000439- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
440 method does not return iterators for the 4th and 5th items.
441
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000442- Issue #4209: Enabling unicode_literals and the print_function in the same
443 __future__ import didn't work.
444
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000445- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000446 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000447
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000448- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
449 returned a path longer than MAX_PATH. (But It's doubtful this code path is
450 really executed because I cannot move to such directory on win2k)
451
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000452- Issue #4069: When set.remove(element) is used with a set element, the element
453 is temporarily replaced with an equivalent frozenset. But the eventual
454 KeyError would always report the empty frozenset([]) as the missing key. Now
455 it correctly refers to the initial element.
456
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000457- Issue #4509: Various issues surrounding resize of bytearray objects to
458 which there are buffer exports.
459
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000460- Issue #4748: Lambda generators no longer return a value.

468
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000469- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
470 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000471
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000472- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
473 returned them on 64bit platforms.
474
Walter Dörwalded960ac2009-05-03 22:36:33 +0000475- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
476 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
477 step. This avoids problems with counting UTF-8 bytes that ignores the effect
478 of using the replace error handler in PyUnicode_DecodeUTF8().
479
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000480- Issue #3739: The unicode-internal encoder now reports the number of characters
481 consumed like any other encoder (instead of the number of bytes).

520
Nick Coghlan49868cb2009-11-15 07:30:34 +0000521- Issue #6816: runpy now provides a run_path function that allows Python code
522 to execute file paths that refer to source or compiled Python files as well
523 as zipfiles, directories and other valid sys.path entries that contain a
524 __main__.py file. This allows applications that run other Python scripts to
525 support the same flexibility as the CPython command line itself.

1701 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1702 the same behaviour as test_ttkguionly (and now also test_tk) which is to

Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001721 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001722 from test support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001823- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1824
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001825- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1826 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1827 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1828 ``printf`` function, whereas PyString_FromFormat has an independent
1829 implementation and uses "%zd" on all platforms for size_t values.
1830 This makes a difference on win64, where ``printf`` needs "%Id" to display
1831 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001833- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1837 object; previously an int would be returned for small values. the __long__
1838 method is allowed to return either an int or a long, but the behaviour of
1839 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001841- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001847 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001848 was correctly parsed but parsing of subsequent arguments failed.
1849
Vinay Sajip35e3b032008-09-01 14:33:59 +00001850- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001851 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1852 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1853 when given a tuple of classes as second argument, were looking up
1854 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1855 type object.
1856
Neal Norwitz18aa3882008-08-24 05:04:52 +00001857- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001994What's New in Python 2.6 beta 3?
1995================================
1996
Barry Warsaw07a4a382008-08-21 01:15:08 +00001997*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001998
1999Core and Builtins
2000-----------------
2001
Guido van Rossumf8402962008-08-20 15:01:50 +00002002- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2003 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2004 extensions do not automatically benefit from the class attribute
2005 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2006 to their tp_flags field if they care. This is a backwards
2007 compatibility feature; in 3.0, all types will use the cache by
2008 default.
2009
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002010- Keyword arguments can now follow starred arguments. (``f(a, *args,
2011 keyword=23)`` is now valid syntax.)
2012
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002013- ctypes function pointers that are COM methods have a boolean True
2014 value again.
2015
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002016- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2017 by denying s# to parse objects that have a releasebuffer procedure,
2018 and introducing s*.
2019
Georg Brandl1e13ea92008-08-11 09:07:59 +00002020- Issue #3537: Fix an assertion failure when an empty but presized dict
2021 object was stored in the freelist.
2022
Mark Dickinsonb6467572008-08-04 21:30:09 +00002023- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2024 ValueError consistently across platforms.
2025
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002026- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2027 (64bit Unix, for example), unichr() would truncate its argument and return
2028 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2029
Neal Norwitze7d8be82008-07-31 17:17:14 +00002030- Apply security patches from Apple.
2031
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002032- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2033 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2034
Antoine Pitrou92f82162008-07-25 22:22:08 +00002035- Issue #1819: function calls with several named parameters are now on
2036 average 35% faster (as measured by pybench).
2037
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002038- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2039 the python debugger steps into a class statement: the free variables (local
2040 variables defined in an outer scope) would be deleted from the outer scope.
2041
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002042- Issue #2620: Overflow checking when allocating or reallocating memory
2043 was not always being done properly in some python types and extension
2044 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2045 all been updated to perform better checks and places in the code that
2046 would previously leak memory on the error path when such an allocation
2047 failed have been fixed.
2048
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002049Library
2050-------
2051
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002052- Issue #3612: Added some missing basic types in ctypes.wintypes.
2053
Benjamin Petersone977ad42008-08-20 01:42:01 +00002054- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2055 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2056
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002057- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2058 version reported by these tools does not necessarily follow the python
2059 version numbering scheme, so the module is less strict when parsing it.
2060
Nick Coghlanf70385a2008-08-18 12:42:46 +00002061- Issue #2235: Added Py3k warnings for types which will become unhashable
2062 under the stricter __hash__ inheritance rules in 3.0. Several types
2063 which did not meet the rules for hash invariants and were already
2064 unhashable in 3.0 have now been explicitly flagged as unhashable in
2065 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2066 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2067
Brett Cannon88f801d2008-08-18 00:46:22 +00002068- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2069 imported into the module but exposed as part of the module's API.
2070
Brett Cannon7b96f072008-08-18 00:41:11 +00002071- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2072
Brett Cannon46225e72008-08-18 00:36:52 +00002073- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2074
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002075- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2076
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002077- Issue #3575: Incremental decoder's decode function now takes bytearray
2078 by using 's*' instead of 't#'.
2079
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002080- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002081 fails unicode conversion on 2nd parameter. (windows only)
2082
Facundo Batista94f243a2008-08-17 03:38:39 +00002083- Issue 2464. urllib2 now supports a malformation in the URL received
2084 in a redirect.
2085
Brett Cannonabe423e2008-08-16 21:47:07 +00002086- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002087 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002088
Facundo Batistaeb90b782008-08-16 14:44:07 +00002089- Issue #2776: fixed small issue when handling an URL with double slash
2090 after a 302 response in the case of not going through a proxy.
2091
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002092- Issue #2676: in the email package, content-type parsing was hanging on
2093 pathological input because of quadratic or exponential behaviour of a
2094 regular expression.
2095
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002096- Issue #3476: binary buffered reading through the new "io" library is now
2097 thread-safe.
2098
Brett Cannonbf3157b2008-08-14 05:00:03 +00002099- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2100 since mimetools itself is deprecated. Because modules are cached, all
2101 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2102
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002103- Issue #3134: shutil referenced undefined WindowsError symbol.
2104
Robert Schuppenies14646332008-08-10 11:01:53 +00002105- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2106 menu entries were not deleted.
2107
Brett Cannon83e81842008-08-09 23:30:55 +00002108- Copied the implementation of reduce() to _functools.reduce() to have a
2109 version that did not raise a DeprecationWarning under -3.
2110
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002111- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2112 a MemoryError rather than silently stop the iteration.
2113
Guido van Rossum59ce9012008-08-09 14:55:34 +00002114- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2115 to _sre.compile() will now be rejected. This should not affect anybody
2116 since the re.compile() function never generates invalid re-bytecode.
2117
Skip Montanaroa032bf42008-08-08 22:52:51 +00002118- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2119 upon first access it can be automatically initialized from the csv file if
2120 it wasn't initialized during instantiation.
2121
Brett Cannon3aa2a492008-08-06 22:28:09 +00002122- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2123 the reload() built-in has been removed.
2124
Brett Cannon7e30b672008-08-04 21:52:25 +00002125- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002126 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00002127 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
2128 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2129 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2130 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2131 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002132
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002133- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2134 raised an AttributeError.
2135
Benjamin Peterson01a24322008-07-28 23:35:27 +00002136- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002137 asking for a specific length. This problem only affected files opened
2138 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002139
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002140- Issue #3449: Update decimal module to use most recent specification
2141 (v. 1.68) and tests (v. 2.58) from IBM.
2142
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002143- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
2144
Raymond Hettinger8c664e82008-07-25 18:43:33 +00002145- Issue 1592: Improve error reporting when operations are attempted
2146 on a closed shelf.

2149
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002150- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
2151
2152- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2153 invalid arguments.
2154
2155- Issue #3302: Fix several crashes when calling locale's gettext functions
2156 with None arguments.
2157
2158- Issue #3389: Allow resolving dotted names for handlers in logging
2159 configuration files.
2160
2161- Deprecate the sunaudio module for removal in Python 3.0.
2162
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002163- Issue #3394: zipfile.writestr sets external attributes when passed a
2164 file name rather than a ZipInfo instance, so files are extracted with
2165 mode 0600 rather than 000 under Unix.
2166
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002167- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2168 argument in python 2.5, this broke code that subclassed Popen to include its
2169 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2177-------------
2178
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002179- Issue #2235: the C API function PyObject_HashNotImplemented and its
2180 interaction with the tp_hash slot (added in 2.6b2) are now documented
2181
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002182- Issue #643841: The language reference now provides more detailed
2183 coverage of the lookup process for special methods. The disclaimers
2184 regarding lack of coverage of new-style classes have also been
2185 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002188What's New in Python 2.6 beta 2?
2189================================
2190
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002191*Release date: 17-Jul-2008*
2192
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002193Core and Builtins
2194-----------------
2195
Georg Brandl3e483f62008-07-16 22:57:41 +00002196- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2197 its methods now allow for items objects that can be converted to
2198 an integer using operator.index().
2199
Mark Dickinson64b7e502008-07-16 09:40:03 +00002200- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2201 produced a ValueError instead of giving the correct float.
2202
Eric Smitha5fa5a22008-07-16 00:11:49 +00002203- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2204 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2205
Mark Dickinson7103aa42008-07-15 19:08:33 +00002206- Issue #3008: the float type has a new instance method 'float.hex'
2207 and a new class method 'float.fromhex' to convert floating-point
2208 numbers to and from hexadecimal strings, respectively.
2209
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002210- Issue #2235: __hash__ is once again inherited by default. To allow
2211 collections.Hashable to remain meaningful in the presence of the
2212 default hash implementation (object.__hash__), it is now possible
2213 to explicit block inheritance of hash by setting __hash__=None at
2214 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2215 level.
2216
Nick Coghlanb028f502008-07-13 14:52:36 +00002217- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2218 the parent module cannot be found while performing an absolute import.
2219 This means that an incorrectly defined __package__ attribute will
2220 now only prevent relative imports in that module rather than causing
2221 all imports from that module to fail.
2222
Nick Coghlan14ff9942008-07-08 14:21:42 +00002223- Issue #2517: Allow unicode messages in Exceptions again by correctly
2224 bypassing the instance dictionary when looking up __unicode__ on
2225 new-style classes.
2226
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002227- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2228 set to a custom object whose write() method happens to install
2229 another file in sys.stdout.
2230
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002231- Issue #3088: Corrected a race condition in classes derived from
2232 threading.local: the first member set by a thread could be saved in
2233 another thread's dictionary.
2234
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002235- Issue #3004: Minor change to slice.indices(): the start and stop
2236 arguments are now treated identically, making the behaviour easier
2237 to describe and understand. For example, slice(None, -10,
2238 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2239 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2240 10, -1).
2241
Georg Brandl278fc502008-07-19 12:46:12 +00002242- Issue #3219: Calling a function with repeated keyword arguments,
2243 f(a=2, a=23), would not cause a syntax error. This was a regression
2244 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002245
Georg Brandl278fc502008-07-19 12:46:12 +00002246- Issue #2862: Make int and float freelist management consistent with
2247 other freelists. Changes their CompactFreeList apis into
2248 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002249

2251-------
2252
Thomas Heller57adf222008-08-14 19:10:48 +00002253- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2254 api functions without holding the GIL, which could lead to a fatal
2255 error when they failed.
2256
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002257- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002265- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2266 ForkingPickler.register() to resolve conflict with ctypes.
2267
Vinay Sajip51e65192008-07-18 09:01:10 +00002268- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2271 a valid dlerror() message.
2272
Thomas Heller2bad6572008-07-15 17:19:50 +00002273- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2274 incomplete structure was created.
2275
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002276- Issue #3339: dummy_thread.acquire() should not return None.
2277
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002278- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2279

2693 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002694 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002695
2696 This is controlled by the configure argument ``--with-universal-archs``:
2697
2698 - ``--with-universal-archs=all``: install 4-way universal
2699
2700 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2701
2702 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2703
2704 This option should be used in combination with ``--enable-universalsdk=``.
2705
2706 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2743 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002744
Christian Heimese74c8f22008-04-19 02:23:57 +00002745- Added kill, terminate and send_signal(sig) to subprocess.Popen.
2746
Georg Brandl3ee81df2008-05-17 18:14:43 +00002747- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
2748 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00002749
Georg Brandl3ee81df2008-05-17 18:14:43 +00002750- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00002756- Issue #1631171: Re-implement the 'warnings' module in C (the
2757 original Python code has been kept as backup). This will allow for
2758 using the 'warning's machinery in such places as the parser where
2759 use of pure Python code is not possible. Both the ``showarning()``
2760 and ``formatwarning()`` gain an optional 'line' argument which is
2761 not called by default for backwards-compatibility reasons. Setting
2762 ``warnings.showwarning()`` to an implementation that lacks support
2763 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +00002786 reference to themselves.
2787
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002788- The getpass module has been improved on Unix. It now uses /dev/tty
2789 by default and uses stderr instead of stdout. A GetPassWarning is
2790 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002791

2803 removed and replaced by pure python code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002805- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002806 extension modules between 32 and 64 bit platforms. See the distutls
2807 build documentation for more information.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002826- Issue #2550: The approach used by client/server code for obtaining
2827 ports to listen on in network-oriented tests has been refined in an
2828 effort to facilitate running multiple instances of the entire
2829 regression test suite in parallel without issue.
2830 test_support.bind_port() has been fixed such that it will always
2831 return a unique port -- which wasn't always the case with the
2832 previous implementation, especially if socket options had been set
2833 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2834 new implementation of bind_port() will actually raise an exception
2835 if it is passed an AF_INET/SOCK_STREAM socket with either the
2836 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2837 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2838 the socket it's been passed. This currently only applies to
2839 Windows. This option prevents any other sockets from binding to the
2840 host/port we've bound to, thus removing the possibility of the
2841 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2842 when a second SOCK_STREAM socket binds and accepts to a host/port
2843 that's already been bound by another socket. The optional preferred
2844 port parameter to bind_port() has been removed. Under no
2845 circumstances should tests be hard coding ports!
2846
2847 test_support.find_unused_port() has also been introduced, which will
2848 pass a temporary socket object to bind_port() in order to obtain an
2849 unused port. The temporary socket object is then closed and
2850 deleted, and the port is returned. This method should only be used
2851 for obtaining an unused port in order to pass to an external program
2852 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2853 a parameter to a server-oriented class that doesn't give you direct
2854 access to the underlying socket used.
2855
2856 Finally, test_support.HOST has been introduced, which should be used
2857 for the host argument of any relevant socket calls (i.e. bind and
2858 connect).

3132Core and builtins
3133-----------------
3134
Fred Drakea8ee94b2008-03-01 02:45:07 +00003135- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003136 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003137
Georg Brandlad61bc82008-02-23 15:11:18 +00003138- Issue #2067: file.__exit__() now calls subclasses' close() method.
3139
3140- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003141
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003142- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003143 issue 215555 for a discussion.
3144
Eric Smitha73fbe72008-02-23 03:09:44 +00003145- Added the future_builtins module, which contains hex() and oct().
3146 These are the PEP 3127 version of these functions, designed to be
3147 compatible with the hex() and oct() builtins from Python 3.0. They
3148 differ slightly in their output formats from the existing, unchanged
3149 Python 2.6 builtins. The expected usage of the future_builtins
3150 module is:
3151 from future_builtins import hex, oct
3152
Eric Smith7ef40bf2008-02-20 23:34:22 +00003153- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3154 exponents for exponents with absolute value < 100. Follows C99
3155 standard. This is a change on Windows, which would use 3 digits.
3156 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3157 so that any alterations it does to the resulting string will be
3158 available in stringlib/formatter.h (for float.__format__).
3159
Eric Smith5a3c1352008-02-19 13:21:56 +00003160- Implemented PEP 3101, Advanced String Formatting. This adds a new
3161 builtin format(); a format() method for str and unicode; a
3162 __format__() method to object, str, unicode, int, long, float, and
3163 datetime; the class string.Formatter; and the C API
3164 PyObject_Format().
3165
Georg Brandl3ee81df2008-05-17 18:14:43 +00003166- Fixed several potential crashes, all caused by specially crafted
3167 __del__ methods exploiting objects in temporarily inconsistent
3168 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003169
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003170- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171 prevent a possible crash: an Abstract Base Class would try to access
3172 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003173
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174- Fixed repr() and str() of complex numbers with infinity or nan as
3175 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003176
Georg Brandl3ee81df2008-05-17 18:14:43 +00003177- Clear all free lists during a gc.collect() of the highest generation
3178 in order to allow pymalloc to free more arenas. Python may give back
3179 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003180
Georg Brandl3ee81df2008-05-17 18:14:43 +00003181- Issue #2045: Fix an infinite recursion triggered when printing a
3182 subclass of collections.defaultdict, if its default_factory is set
3183 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003184
Christian Heimesf75dbef2008-02-08 00:11:31 +00003185- Fixed a minor memory leak in dictobject.c. The content of the free
3186 list was not freed on interpreter shutdown.
3187
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188- Limit free list of method and builtin function objects to 256
3189 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003190
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3192 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003193 to compact the internal free lists of pre-allocted ints and floats.
3194
Georg Brandl3ee81df2008-05-17 18:14:43 +00003195- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3196 calls. Python expected the return type int but the fork familie
3197 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003198
Georg Brandl3ee81df2008-05-17 18:14:43 +00003199- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3200 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003201
Georg Brandl3ee81df2008-05-17 18:14:43 +00003202- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3203 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003204
Georg Brandl3ee81df2008-05-17 18:14:43 +00003205- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3206 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003207
Georg Brandl3ee81df2008-05-17 18:14:43 +00003208- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3209 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003210
Georg Brandl3ee81df2008-05-17 18:14:43 +00003211- Patch #1473257: generator objects gain a gi_code attribute. This is
3212 the same object as the func_code attribute of the function that
3213 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003214
Georg Brandl3ee81df2008-05-17 18:14:43 +00003215- Issue #1920: "while 0" statements were completely removed by the
3216 compiler, even in the presence of an "else" clause, which is
3217 supposed to be run when the condition is false. Now the compiler
3218 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003219
Guido van Rossumeead05f2008-01-24 18:21:02 +00003220- A few crashers fixed: weakref_in_del.py (issue #1377858);
3221 loosing_dict_ref.py (issue #1303614, test67.py);
3222 borrowed_ref_[34].py (not in tracker).
3223
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003224- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003225 suppressed while an extension is loaded by calling SetErrorMode in
3226 dynload_win.c. The error is still reported properly.
3227
Georg Brandl3ee81df2008-05-17 18:14:43 +00003228- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003229 several extension methods and modules do not work without unicode
3230 support.
3231
Georg Brandl26543b12008-01-21 18:36:51 +00003232- Issue #1882: when compiling code from a string, encoding cookies in the
3233 second line of code were not always recognized correctly.
3234
Georg Brandl14404b62008-01-19 19:27:05 +00003235- Issue #1679: "0x" was taken as a valid integer literal.
3236
Georg Brandl6caad7d2008-01-26 14:19:22 +00003237- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003238 added.
3239
Christian Heimesc94e2b52008-01-14 04:13:37 +00003240- sys.float_info / PyFloat_GetInfo: The floating point information
3241 object was converted from a dict to a specialized structseq object.
3242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- Patch #1816: Added sys.flags structseq. It exposes the status of
3244 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003245
Georg Brandl3ee81df2008-05-17 18:14:43 +00003246- Objects/structseq.c: Implemented new structseq representation. The
3247 patch makes structseqs (e.g. the return value of os.stat) more
3248 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Patch #1700288: added a type attribute cache that caches method
3251 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003252
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003253- Bug #1776: __import__() no longer accepts filenames on any platform.
3254 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003255
Georg Brandlaed6c662008-01-07 17:25:53 +00003256- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3257
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3259 envvar and sys.dont_write_bytecode attribute. All these can be set
3260 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003261
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262- Improve some exception messages when Windows fails to load an
3263 extension module. Now we get for example '%1 is not a valid Win32
3264 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003265
Georg Brandl3ee81df2008-05-17 18:14:43 +00003266- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00003267
Georg Brandl3ee81df2008-05-17 18:14:43 +00003268- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3269 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003270
Christian Heimes0a8143f2007-12-18 23:22:54 +00003271- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003272 and INF. float("nan"), float("inf") and float("-inf") now work on
3273 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003274
Georg Brandl3ee81df2008-05-17 18:14:43 +00003275- Compiler now generates simpler and faster code for dictionary
3276 literals. The oparg for BUILD_MAP now indicates an estimated
3277 dictionary size. There is a new opcode, STORE_MAP, for adding
3278 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003279
Georg Brandl3ee81df2008-05-17 18:14:43 +00003280- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00003281
Georg Brandl3ee81df2008-05-17 18:14:43 +00003282- Issue #1620: New property decorator syntax was modifying the
3283 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003284
Georg Brandl3ee81df2008-05-17 18:14:43 +00003285- Issue #1538: Avoid copying string in split/rsplit if the split char
3286 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003287
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003288- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003289 SystemError.
3290
Nick Coghlanef01d822007-12-03 12:55:17 +00003291- PEP 366: Allow explicit relative imports when executing modules
3292 inside packages with the -m switch via a new module level
3293 __package__ attribute.
3294
Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Issue #1402: Fix a crash on exit, when another thread is still
3296 running, and if the deallocation of its frames somehow calls the
3297 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003298

3308 file can now be directly executed by passing their name to the
3309 interpreter. The directory/zipfile is automatically inserted as the
3310 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003311
Georg Brandl3ee81df2008-05-17 18:14:43 +00003312- Issue #1265: Fix a problem with sys.settrace, if the tracing
3313 function uses a generator expression when at the same time the
3314 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003315
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003316- sets and frozensets now have an isdisjoint() method.
3317
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003318- optimize the performance of builtin.sum().
3319
Neal Norwitz44f326e2007-10-05 05:29:17 +00003320- Fix warnings found by the new version of the Coverity checker.
3321
Georg Brandl3ee81df2008-05-17 18:14:43 +00003322- The enumerate() builtin function is no longer bounded to sequences
3323 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3324 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003325
Georg Brandl3ee81df2008-05-17 18:14:43 +00003326- Issue #1686386: Tuple's tp_repr did not take into account the
3327 possibility of having a self-referential tuple, which is possible
3328 from C code. Nor did object's tp_str consider that a type's tp_str
3329 could do something that could lead to an inifinite recursion.
3330 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3331 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003332
Georg Brandl3ee81df2008-05-17 18:14:43 +00003333- Issue #1164: It was possible to trigger deadlock when using the
3334 'print' statement to write to a file since the GIL was not released
3335 as needed. Now PyObject_Print() does the right thing along with
3336 various tp_print implementations of the built-in types and those in
3337 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003339- Issue #1147: Exceptions were directly allowing string exceptions in
3340 their throw() method even though string exceptions no longer
3341 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003342
Georg Brandl3ee81df2008-05-17 18:14:43 +00003343- Issue #1096: Prevent a segfault from getting the repr of a very
3344 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003345
Brett Cannon1e534b52007-09-07 04:18:30 +00003346- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003347 PyObject_Call() never calling back out to Python code to trigger
3348 recursion depth updates/checks. Required the creation of a static
3349 RuntimeError instance in case normalizing an exception put the
3350 recursion check value past its limit. Fixes crashers
3351 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003352

Neal Norwitz0ac60192007-05-27 04:08:54 +00003366- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003367 __*__ attributes. (Some already existed, e.g., __doc__ and
3368 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003369
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003370- Add -3 option to the interpreter to warn about features that are
3371 deprecated and will be changed/removed in Python 3.0.
3372

3374 calls.
3375
Collin Winter62903052007-05-18 23:11:24 +00003376- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003377 "except E as target:". This is to provide forwards compatibility
3378 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003379
Brett Cannon229cee22007-05-05 01:34:02 +00003380- Deprecate BaseException.message as per PEP 352.
3381
Georg Brandl3ee81df2008-05-17 18:14:43 +00003382- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003383 inherited from a builtin base.
3384
Vinay Sajip8549ce32007-05-06 17:53:37 +00003385- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003386 setting a plain string, ie don't expand to single letter identifiers.
3387
Raymond Hettinger13936692007-04-11 18:40:58 +00003388- Request #1191699: Slices can now be pickled.
3389
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003390- Request #1193128: str.translate() now allows a None argument for
3391 translations that only remove characters without re-mapping the
3392 remaining characters.
3393
Georg Brandl5cb76c12007-03-21 09:00:39 +00003394- Patch #1682205: a TypeError while unpacking an iterable is no longer
3395 masked by a generic one with the message "unpack non-sequence".
3396
Neal Norwitzaa754b72007-03-21 06:39:48 +00003397- Remove unused file Python/fmod.c.
3398
Guido van Rossum143b5642007-03-23 04:58:42 +00003399- Bug #1683368: The object.__init__() and object.__new__() methods are
3400 now stricter in rejecting excess arguments. The only time when
3401 either allows excess arguments is when it is not overridden and the
3402 other one is. For backwards compatibility, when both are
3403 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003404 warning later). Also, type.__init__() insists on the same signature
3405 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003406
Georg Brandl3ee81df2008-05-17 18:14:43 +00003407- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3408 object to complex using its __complex__() method before falling back
3409 to the __float__() method. Therefore, the functions in the cmath
3410 module now can operate on objects that define a __complex__()
3411 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003412
Georg Brandl3ee81df2008-05-17 18:14:43 +00003413- Patch #1623563: allow __class__ assignment for classes with
3414 __slots__. The old and the new class are still required to have the
3415 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003416

3421 ``object.__reduce_ex__()`` is called with an object that is faking
3422 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003423
Georg Brandl3ee81df2008-05-17 18:14:43 +00003424- Patch #1680015: Don't modify __slots__ tuple if it contains an

3428
Georg Brandl7b9c5552007-03-12 14:30:05 +00003429- Bug #1678647: write a newline after printing an exception in any
3430 case, even when converting the value to a string failed.
3431
Georg Brandl871f1bc2007-03-12 13:17:36 +00003432- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433 its argument, if it exists. If not, it will work like before. This
3434 allows customizing the output of dir() in the presence of a
3435 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003436
Collin Winter276887b2007-03-12 16:11:39 +00003437- Patch #922167: Python no longer segfaults when faced with infinitely
3438 self-recursive reload() calls (as reported by bug #742342).
3439

3444 parthensized forms. This means complex(repr(x)) now works instead of
3445 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003446
Georg Brandlaa2321b2007-03-07 00:40:28 +00003447- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448 makes the filenames the warning module prints much more sensible
3449 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003450
Georg Brandl49aafc92007-03-07 00:34:46 +00003451- Variant of patch #697613: don't exit the interpreter on a SystemExit
3452 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003453 variable is given, but break into the interactive interpreter just
3454 like on other exceptions or normal program exit.

3460 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003461
Georg Brandl0fca97a2007-03-05 22:28:08 +00003462- Patch #1674228: when assigning a slice (old-style), check for the
3463 sq_ass_slice instead of the sq_slice slot.
3464
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- When printing an unraisable error, don't print exceptions. before
3466 the name. This duplicates the behavior whening normally printing
3467 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003475- Bug #1377858: Fix the segfaulting of the interpreter when an object
3476 created a weakref on itself during a __del__ call for new-style
3477 classes (classic classes still have the bug).

4076 Python would crash instead of raising an error.
4077

4090
Georg Brandl3ee81df2008-05-17 18:14:43 +00004091- unittest now verifies more of its assumptions. In particular,

4093 accepted in TestSuite.addTest(). This should cause no
4094 incompatibility since it never made sense with ordinary subclasses
4095 -- the failure just occurred later, with a more cumbersome
4096 exception.

4379 obtained from the TLS negotiation itself. Patch contributed by Bill
4380 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004381
Georg Brandl3ee81df2008-05-17 18:14:43 +00004382- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004383 that the SMTP.starttls() caller no longer needs to call ehlo()
4384 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004385 does not claim to support starttls. Adds the
4386 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4467 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4468 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004485 time so that opening a database previously created with the DB_DUP
4486 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4487 opens. Specifically: dictionary assignment to a DB object will
4488 replace all values for a given key when the database allows
4489 duplicate values. DB users should use DB.put(k, v) when they want
4490 to store duplicates; not DB[k] = v.

4497 characters with ASCII value less than 32. Also, it correctly quotes
4498 dots only if they occur on a single line, as opposed to the previous
4499 behavior of quoting dots if they are the second character of any
4500 line.

Neal Norwitz92422fb2006-08-18 03:57:54 +00004822C API
4823-----
4824
Georg Brandl3ee81df2008-05-17 18:14:43 +00004825- Unified naming convention for free lists and their limits. All free
4826 lists in Object/ are named ``free_list``, the counter ``numfree``
4827 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4828 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004829
Georg Brandl3ee81df2008-05-17 18:14:43 +00004830- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4831 to ``PyTuple_SetItem``, it can be used to populate a brand new
4832 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004833
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004834- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004836- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4837 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4838 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004839
4840- Patch #1720595: add T_BOOL to the range of structmember types.
4841
4842- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4843 ``PyFloat_GetInfo()`` to the float API.
4844
Georg Brandl3ee81df2008-05-17 18:14:43 +00004845- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4846 of w# format code incorrectly truncated the length to an int, even
4847 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4848 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004849
Georg Brandl3ee81df2008-05-17 18:14:43 +00004850- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4851 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004852
Georg Brandl3ee81df2008-05-17 18:14:43 +00004853- PEP 3123: Provide forward compatibility with Python 3.0, while
4854 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4855 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004856
Georg Brandl3ee81df2008-05-17 18:14:43 +00004857- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4858 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004859
4860- Patch #1733960: Allow T_LONGLONG to accept ints.
4861

4867
4868- Fix some leftovers from the conversion from int to Py_ssize_t
4869 (relevant to strings and sequences of more than 2**31 items).
4870
4871- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4872 outside of pystate.c and should not be necessary.
4873
Georg Brandl3ee81df2008-05-17 18:14:43 +00004874- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4875 absolute imports. In earlier versions they might have used relative
4876 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004877
Georg Brandl3ee81df2008-05-17 18:14:43 +00004878- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4879 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004880
Georg Brandl3ee81df2008-05-17 18:14:43 +00004881- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4882 macro so it can be used as an expression.

4887
Georg Brandl3ee81df2008-05-17 18:14:43 +00004888- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4889 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4890 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4891 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004892
Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004906- Removed the macfs module. It had been deprecated since Python 2.5.
4907 This lead to the deprecation of macostools.touched() as it relied
4908 solely on macfs and was a no-op under OS X.
