Barry Warsaw12582c92008-10-02 03:33:51 +00007What's New in Python 2.7 alpha 1
8================================

11
12Core and Builtins
13-----------------
14
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000015- Add Py3k warnings for parameter names in parenthesis.
16
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000017- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000018
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000019- Issue #7085: Fix crash when importing some extensions in a thread
20 on MacOSX 10.6.
21
Mark Dickinsonb678de82009-11-19 18:41:49 +000022- Issue #7117: repr(x) for a float x returns a result based on the
23 shortest decimal string that's guaranteed to round back to x under
24 correct rounding (with round-half-to-even rounding mode).
25 Previously it gave a string based on rounding x to 17 decimal digits.
26 repr(x) for a complex number behaves similarly. On platforms where
27 the correctly-rounded strtod and dtoa code is not supported (see below),
28 repr is unchanged.
29
30- Issue #7117: On almost all platforms: float-to-string and
31 string-to-float conversions within Python are now correctly rounded.
32 Places these conversions occur include: str for floats and complex
33 numbers; the float and complex constructors; old-style and new-style
34 numeric formatting; serialization and deserialization of floats and
35 complex numbers using marshal, pickle and json; parsing of float and
36 imaginary literals in Python code; Decimal-to-float conversion.
37
38 The conversions use a Python-adapted version of David Gay's
39 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
40 functions. This code is supported on Windows, and on Unix-like
41 platforms using gcc, icc or suncc as the C compiler. There may be a
42 small number of platforms on which correct operation of this code
43 cannot be guaranteed, so the code is not used: notably, this applies
44 to platforms where the C double format is not IEEE 754 binary64, and
45 to platforms on x86 hardware where the x87 FPU is set to 64-bit
46 precision and Python's configure script is unable to determine how
47 to change the FPU precision. On these platforms conversions use the
48 platform strtod and dtoa, as before.
49
Mark Dickinsonbd15a062009-11-18 19:33:35 +000050- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +000051 now uses the correctly-rounded string <-> float conversions
52 described above (when available), and so produces correctly rounded
53 results that will display nicely under the float repr. There are
54 two related small changes: (1) round now accepts any class with an
55 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +000056 floats for the second argument), and (2) an excessively large second
57 integer argument (e.g., round(1.234, 10**100)) no longer raises an
58 exception.
59
Philip Jenveyfab8be22009-11-17 02:42:26 +000060- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
61
Benjamin Petersone36199b2009-11-12 23:39:44 +000062- Fix several issues with compile(). The input can now contain Windows and Mac
63 newlines and is no longer required to end in a newline.
64
Mark Dickinsonc04c7c52009-10-26 22:28:14 +000065- Remove length limitation when constructing a complex number from a
66 unicode string.
67
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +000068- Issue #7244: itertools.izip_longest() no longer ignores exceptions
69 raised during the formation of an output tuple.
70

84 is the only object holding a reference to it.
85
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +000086- Issue #1754094: Improve the stack depth calculation in the compiler.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000186- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
187 statement and correctly lookup the __enter__ and __exit__ special methods.
188
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000189- Issue #5829: complex("1e500") no longer raises OverflowError. This
190 makes it consistent with float("1e500") and interpretation of real
191 and imaginary literals.
192
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000193- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

199
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000200- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
201 (1) inf and nan strings with trailing whitespace were incorrectly
202 rejected; (2) parsing of strings representing infinities and nans
203 was locale aware; and (3) the interpretation of fromhex('-nan')
204 didn't match that of float('-nan').
205
Eric Smitha985a3a2009-05-05 18:26:08 +0000206- Issue #5920: For float.__format__, change the behavior with the
207 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
208 to be like 'g' but with at least one decimal point and with a
209 default precision of 12. Previously, the behavior the same but with
210 a default precision of 6. This more closely matches str(), and
211 reduces surprises when adding alignment flags to the empty
212 presentation type. This also affects the new complex.__format__ in
213 the same way.
214
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000215- Issue #5890: in subclasses of 'property' the __doc__ attribute was
216 shadowed by classtype's, even if it was None. property now
217 inserts the __doc__ into the subclass instance __dict__.
218
Antoine Pitrou653dece2009-05-04 18:32:32 +0000219- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

221
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000222- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000223 format(complex(1, 2./3), '.5') now produces a sensible result.
224
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000225- Issue #5864: Fix empty format code formatting for floats so that it
226 never gives more than the requested number of significant digits.
227
Eric Smithcac7af62009-04-27 19:04:37 +0000228- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
229 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
230
Martin v. Löwis99f27792009-04-26 00:53:18 +0000231- Issue #4971: Fix titlecase for characters that are their own
232 titlecase, but not their own uppercase.
233
Eric Smith068f0652009-04-25 21:40:15 +0000234- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
235 _PyOS_double_to_string or PyOS_double_to_string.
236
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000237- Issue #5283: Setting __class__ in __del__ caused a segfault.
238
Mark Dickinson95bc9802009-04-24 12:46:53 +0000239- Issue #5816: complex(repr(z)) now recovers z exactly, even when
240 z involves nans, infs or negative zeros.
241
Eric Smithaca19e62009-04-22 13:29:05 +0000242- Implement PEP 378, Format Specifier for Thousands Separator, for
243 floats, ints, and longs.
244
245- Issue #5515: 'n' formatting for ints, longs, and floats handles
246 leading zero formatting poorly.
247
248- Issue #5772: For float.__format__, don't add a trailing ".0" if
249 we're using no type code and we have an exponent.
250
Mark Dickinson6736cf82009-04-20 21:13:33 +0000251- Issue #3166: Make long -> float (and int -> float) conversions
252 correctly rounded.
253

255 some builtin types.
256
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000257- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000258 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000259
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000260- Issue #5759: float() didn't call __float__ on str subclasses.
261
Georg Brandl3c4a5462009-04-12 12:08:12 +0000262- Issue #5704: the "-3" command-line option now implies "-t".
263
R. David Murray0374a822009-04-09 21:54:50 +0000264- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
265 its clarity and its speed.
266

275 the end sys.path, for compatibility with the system install of Python.
276
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000277- Issue #4688: Add a heuristic so that tuples and dicts containing only
278 untrackable objects are not tracked by the garbage collector. This can
279 reduce the size of collections and therefore the garbage collection overhead
280 on long-running programs, depending on their particular use of datatypes.
281
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000282- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
283 improve its performance. Long divisions and remainder operations
284 are now between 50% and 150% faster.
285
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000286- Issue #4258: Make it possible to use base 2**30 instead of base
287 2**15 for the internal representation of integers, for performance
288 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
289 --enable-big-digits option to configure, which overrides the
290 default. Add sys.long_info structseq to provide information about
291 the internal format.
292
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000293- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
294 result traceback.__members__ no longer exists.)
295
Mark Dickinson6b265f12009-03-18 16:07:26 +0000296- Issue #4474: PyUnicode_FromWideChar now converts characters outside
297 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
298 and sizeof(Py_UNICODE) == 2.
299
Eric Smith6f42edb2009-03-14 11:57:26 +0000300- Issue #5237: Allow auto-numbered fields in str.format(). For
301 example: '{} {}'.format(1, 2) == '1 2'.
302
Brett Cannon6c4cff02009-03-11 04:51:06 +0000303- Issue #3652: Make the 'line' argument for warnings.showwarning() a
304 requirement. Means the DeprecationWarning from Python 2.6 can go away.
305

307 used when using str.format() with str, unicode, long, int, and
308 float arguments.
309
Raymond Hettinger08259e82009-02-18 23:10:19 +0000310- Running Python with the -3 option now also warns about classic division
311 for ints and longs.
312
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000313- Issue #5260: Long integers now consume less memory: average
314 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
315 on a 64-bit system.
316
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000317- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

324
Georg Brandl29c6a282009-04-05 20:23:13 +0000325- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000326 were suppressing all exceptions. These include list(), filter(), map(),
327 zip(), and bytearray().
328
Benjamin Peterson596d3062009-01-19 15:42:23 +0000329- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

336
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000337- Issue #4935: The overflow checking code in the expandtabs() method common
338 to str, bytes and bytearray could be optimized away by the compiler, letting
339 the interpreter segfault instead of raising an error.
340
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000341- Issue #3720: Fix a crash when an iterator modifies its class and removes its

347
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000348- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
349 collecting the oldest generation) so that allocating lots of objects without
350 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000351 Martin von Löwis at

355
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000356- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
357 an existing .py counterpart, override the co_filename attributes of all
358 code objects if the original filename is obsolete (which can happen if the
359 file has been renamed, moved, or if it is accessed through different paths).
360 Patch by Ziga Seilnacht and Jean-Paul Calderone.
361
Martin v. Löwis5344c992009-01-02 20:32:55 +0000362- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000364- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
365 file with `str' filename on Windows.
366
Antoine Pitrouaa687902009-01-01 14:11:22 +0000367- Issue #3680: Reference cycles created through a dict, set or deque iterator

369
Nick Coghlan180e4002008-12-30 01:18:48 +0000370- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
371 where the tp_hash and tp_dict slots are both NULL.
372
Benjamin Peterson7af65562008-12-29 17:56:58 +0000373- Issue #4764: With io.open, IOError.filename is set when trying to open a

380 bytearray.translate(). It was always allowed for bytes.translate().
381
Skip Montanarof205c132008-12-23 03:30:15 +0000382- Added test case to ensure attempts to read from a file opened for writing
383 fail.
384
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000385- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

395 context manager returns a value that cannot be converted to a bool.
396
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000397- Issue #4597: Fixed several opcodes that weren't always propagating
398 exceptions.
399
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000400- Issue #4445: Replace "sizeof(PyStringObject)" with
401 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
402 str instances. On a typical machine this saves 3 bytes of memory
403 (on average) per string allocation.
404
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000405- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
406 interpreter to abort ("Fatal Python error: Could not reset the stack!")
407 instead of throwing a MemoryError.
408
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000409- Issue #3689: The list reversed iterator now supports __length_hint__
410 instead of __len__. Behavior now matches other reversed iterators.
411
Benjamin Petersonc078f922008-11-21 22:27:24 +0000412- Issue #4367: Python would segfault during compiling when the unicodedata
413 module couldn't be imported and \N escapes were present.
414
Vinay Sajip213faca2008-12-03 23:22:58 +0000415- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000416 method on file objects with closefd=False. The file descriptor is still
417 kept open but the file object behaves like a closed file. The ``FileIO``
418 object also got a new readonly attribute ``closefd``.
419
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000420- Issue #4348: Some bytearray methods returned that didn't cause any change to
421 the bytearray, returned the same bytearray instead of a copy.
422
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000423- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
424

431
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000432- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
433 method does not return iterators for the 4th and 5th items.
434
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000435- Issue #4209: Enabling unicode_literals and the print_function in the same
436 __future__ import didn't work.
437
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000438- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000439 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000440
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000441- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
442 returned a path longer than MAX_PATH. (But It's doubtful this code path is
443 really executed because I cannot move to such directory on win2k)
444
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000445- Issue #4069: When set.remove(element) is used with a set element, the element
446 is temporarily replaced with an equivalent frozenset. But the eventual
447 KeyError would always report the empty frozenset([]) as the missing key. Now
448 it correctly refers to the initial element.
449
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000450- Issue #4509: Various issues surrounding resize of bytearray objects to

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000465- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
466 returned them on 64bit platforms.
467
Walter Dörwalded960ac2009-05-03 22:36:33 +0000468- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
469 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
470 step. This avoids problems with counting UTF-8 bytes that ignores the effect
471 of using the replace error handler in PyUnicode_DecodeUTF8().
472
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000473- Issue #3739: The unicode-internal encoder now reports the number of characters

503
Nick Coghlan49868cb2009-11-15 07:30:34 +0000504- Issue #6816: runpy now provides a run_path function that allows Python code
505 to execute file paths that refer to source or compiled Python files as well
506 as zipfiles, directories and other valid sys.path entries that contain a
507 __main__.py file. This allows applications that run other Python scripts to

1807
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001808- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1809 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1810 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1811 ``printf`` function, whereas PyString_FromFormat has an independent
1812 implementation and uses "%zd" on all platforms for size_t values.
1813 This makes a difference on win64, where ``printf`` needs "%Id" to display
1814 64bit values.

1820 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001831 was correctly parsed but parsing of subsequent arguments failed.
1832
Vinay Sajip35e3b032008-09-01 14:33:59 +00001833- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001834 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1835 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1836 when given a tuple of classes as second argument, were looking up
1837 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1838 type object.

1983-----------------
1984
Guido van Rossumf8402962008-08-20 15:01:50 +00001985- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1986 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1987 extensions do not automatically benefit from the class attribute
1988 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1989 to their tp_flags field if they care. This is a backwards
1990 compatibility feature; in 3.0, all types will use the cache by
1991 default.

Benjamin Petersonf647dc12008-08-20 01:27:30 +00001993- Keyword arguments can now follow starred arguments. (``f(a, *args,
1994 keyword=23)`` is now valid syntax.)
1995
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001996- ctypes function pointers that are COM methods have a boolean True
1997 value again.
1998
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001999- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2000 by denying s# to parse objects that have a releasebuffer procedure,
2001 and introducing s*.
2002
Georg Brandl1e13ea92008-08-11 09:07:59 +00002003- Issue #3537: Fix an assertion failure when an empty but presized dict
2004 object was stored in the freelist.
2005
Mark Dickinsonb6467572008-08-04 21:30:09 +00002006- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2007 ValueError consistently across platforms.
2008
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002009- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2010 (64bit Unix, for example), unichr() would truncate its argument and return
2011 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2012
Neal Norwitze7d8be82008-07-31 17:17:14 +00002013- Apply security patches from Apple.
2014
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002015- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2016 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2017
Antoine Pitrou92f82162008-07-25 22:22:08 +00002018- Issue #1819: function calls with several named parameters are now on
2019 average 35% faster (as measured by pybench).
2020
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002021- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2022 the python debugger steps into a class statement: the free variables (local
2023 variables defined in an outer scope) would be deleted from the outer scope.
2024
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002025- Issue #2620: Overflow checking when allocating or reallocating memory
2026 was not always being done properly in some python types and extension
2027 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2028 all been updated to perform better checks and places in the code that
2029 would previously leak memory on the error path when such an allocation
2030 failed have been fixed.

2036
Benjamin Petersone977ad42008-08-20 01:42:01 +00002037- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2038 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2039
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002040- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2041 version reported by these tools does not necessarily follow the python
2042 version numbering scheme, so the module is less strict when parsing it.
2043
Nick Coghlanf70385a2008-08-18 12:42:46 +00002044- Issue #2235: Added Py3k warnings for types which will become unhashable
2045 under the stricter __hash__ inheritance rules in 3.0. Several types
2046 which did not meet the rules for hash invariants and were already
2047 unhashable in 3.0 have now been explicitly flagged as unhashable in
2048 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2049 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2050
Brett Cannon88f801d2008-08-18 00:46:22 +00002051- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2052 imported into the module but exposed as part of the module's API.
2053

2059
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002060- Issue #3575: Incremental decoder's decode function now takes bytearray
2061 by using 's*' instead of 't#'.
2062
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002063- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002064 fails unicode conversion on 2nd parameter. (windows only)
2065
Facundo Batista94f243a2008-08-17 03:38:39 +00002066- Issue 2464. urllib2 now supports a malformation in the URL received
2067 in a redirect.

Facundo Batistaeb90b782008-08-16 14:44:07 +00002072- Issue #2776: fixed small issue when handling an URL with double slash
2073 after a 302 response in the case of not going through a proxy.
2074
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002075- Issue #2676: in the email package, content-type parsing was hanging on
2076 pathological input because of quadratic or exponential behaviour of a
2077 regular expression.
2078
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002079- Issue #3476: binary buffered reading through the new "io" library is now
2080 thread-safe.
2081
Brett Cannonbf3157b2008-08-14 05:00:03 +00002082- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2083 since mimetools itself is deprecated. Because modules are cached, all
2084 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2085
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002086- Issue #3134: shutil referenced undefined WindowsError symbol.
2087
Robert Schuppenies14646332008-08-10 11:01:53 +00002088- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2089 menu entries were not deleted.
2090
Brett Cannon83e81842008-08-09 23:30:55 +00002091- Copied the implementation of reduce() to _functools.reduce() to have a
2092 version that did not raise a DeprecationWarning under -3.
2093
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002094- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2095 a MemoryError rather than silently stop the iteration.
2096
Guido van Rossum59ce9012008-08-09 14:55:34 +00002097- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2098 to _sre.compile() will now be rejected. This should not affect anybody
2099 since the re.compile() function never generates invalid re-bytecode.
2100
Skip Montanaroa032bf42008-08-08 22:52:51 +00002101- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2102 upon first access it can be automatically initialized from the csv file if
2103 it wasn't initialized during instantiation.
2104
Brett Cannon3aa2a492008-08-06 22:28:09 +00002105- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2106 the reload() built-in has been removed.
2107
Brett Cannon7e30b672008-08-04 21:52:25 +00002108- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002109 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2117 raised an AttributeError.
2118
Benjamin Peterson01a24322008-07-28 23:35:27 +00002119- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002120 asking for a specific length. This problem only affected files opened
2121 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002122
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002123- Issue #3449: Update decimal module to use most recent specification
2124 (v. 1.68) and tests (v. 2.58) from IBM.

2145
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002146- Issue #3394: zipfile.writestr sets external attributes when passed a
2147 file name rather than a ZipInfo instance, so files are extracted with
2148 mode 0600 rather than 000 under Unix.
2149
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002150- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2151 argument in python 2.5, this broke code that subclassed Popen to include its
2152 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2160-------------
2161
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002162- Issue #2235: the C API function PyObject_HashNotImplemented and its
2163 interaction with the tp_hash slot (added in 2.6b2) are now documented
2164
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002165- Issue #643841: The language reference now provides more detailed
2166 coverage of the lookup process for special methods. The disclaimers
2167 regarding lack of coverage of new-style classes have also been
2168 removed, since the coverage is now fairly reasonable.

2172================================
2173
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002174*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002176Core and Builtins
2177-----------------
2178
Georg Brandl3e483f62008-07-16 22:57:41 +00002179- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2180 its methods now allow for items objects that can be converted to
2181 an integer using operator.index().
2182
Mark Dickinson64b7e502008-07-16 09:40:03 +00002183- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2184 produced a ValueError instead of giving the correct float.
2185
Eric Smitha5fa5a22008-07-16 00:11:49 +00002186- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2187 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2188
Mark Dickinson7103aa42008-07-15 19:08:33 +00002189- Issue #3008: the float type has a new instance method 'float.hex'
2190 and a new class method 'float.fromhex' to convert floating-point
2191 numbers to and from hexadecimal strings, respectively.
2192
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002193- Issue #2235: __hash__ is once again inherited by default. To allow
2194 collections.Hashable to remain meaningful in the presence of the
2195 default hash implementation (object.__hash__), it is now possible
2196 to explicit block inheritance of hash by setting __hash__=None at
2197 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2198 level.
2199
Nick Coghlanb028f502008-07-13 14:52:36 +00002200- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2201 the parent module cannot be found while performing an absolute import.
2202 This means that an incorrectly defined __package__ attribute will
2203 now only prevent relative imports in that module rather than causing
2204 all imports from that module to fail.
2205
Nick Coghlan14ff9942008-07-08 14:21:42 +00002206- Issue #2517: Allow unicode messages in Exceptions again by correctly
2207 bypassing the instance dictionary when looking up __unicode__ on
2208 new-style classes.
2209
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002210- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2211 set to a custom object whose write() method happens to install
2212 another file in sys.stdout.
2213
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002214- Issue #3088: Corrected a race condition in classes derived from
2215 threading.local: the first member set by a thread could be saved in
2216 another thread's dictionary.
2217
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002218- Issue #3004: Minor change to slice.indices(): the start and stop
2219 arguments are now treated identically, making the behaviour easier
2220 to describe and understand. For example, slice(None, -10,
2221 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2222 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2223 10, -1).
2224
Georg Brandl278fc502008-07-19 12:46:12 +00002225- Issue #3219: Calling a function with repeated keyword arguments,
2226 f(a=2, a=23), would not cause a syntax error. This was a regression
2227 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002228
Georg Brandl278fc502008-07-19 12:46:12 +00002229- Issue #2862: Make int and float freelist management consistent with
2230 other freelists. Changes their CompactFreeList apis into
2231 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002232

2234-------
2235
Thomas Heller57adf222008-08-14 19:10:48 +00002236- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2237 api functions without holding the GIL, which could lead to a fatal
2238 error when they failed.
2239
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002240- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2249 ForkingPickler.register() to resolve conflict with ctypes.
2250
Vinay Sajip51e65192008-07-18 09:01:10 +00002251- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2254 a valid dlerror() message.
2255
Thomas Heller2bad6572008-07-15 17:19:50 +00002256- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2257 incomplete structure was created.
2258
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002259- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00002261- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2262
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002263- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002264
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002265- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2266 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002267 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002268 content-length. The problem had been corrected in the 2.4 branch, but never
2269 merged into trunk.
2270
Georg Brandle78fbcc2008-07-05 10:13:36 +00002271- Issue #2663: add filtering capability to shutil.copytree().

2676 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002677 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002678
2679 This is controlled by the configure argument ``--with-universal-archs``:
2680
2681 - ``--with-universal-archs=all``: install 4-way universal
2682
2683 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2684
2685 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2686
2687 This option should be used in combination with ``--enable-universalsdk=``.
2688
2689 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 +00002739- Issue #1631171: Re-implement the 'warnings' module in C (the
2740 original Python code has been kept as backup). This will allow for
2741 using the 'warning's machinery in such places as the parser where
2742 use of pure Python code is not possible. Both the ``showarning()``
2743 and ``formatwarning()`` gain an optional 'line' argument which is
2744 not called by default for backwards-compatibility reasons. Setting
2745 ``warnings.showwarning()`` to an implementation that lacks support
2746 for the ``line`` argument will raise a DeprecationWarning.

2770
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002771- The getpass module has been improved on Unix. It now uses /dev/tty
2772 by default and uses stderr instead of stdout. A GetPassWarning is
2773 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002809- Issue #2550: The approach used by client/server code for obtaining
2810 ports to listen on in network-oriented tests has been refined in an
2811 effort to facilitate running multiple instances of the entire
2812 regression test suite in parallel without issue.
2813 test_support.bind_port() has been fixed such that it will always
2814 return a unique port -- which wasn't always the case with the
2815 previous implementation, especially if socket options had been set
2816 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2817 new implementation of bind_port() will actually raise an exception
2818 if it is passed an AF_INET/SOCK_STREAM socket with either the
2819 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2820 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2821 the socket it's been passed. This currently only applies to
2822 Windows. This option prevents any other sockets from binding to the
2823 host/port we've bound to, thus removing the possibility of the
2824 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2825 when a second SOCK_STREAM socket binds and accepts to a host/port
2826 that's already been bound by another socket. The optional preferred
2827 port parameter to bind_port() has been removed. Under no
2828 circumstances should tests be hard coding ports!
2829
2830 test_support.find_unused_port() has also been introduced, which will
2831 pass a temporary socket object to bind_port() in order to obtain an
2832 unused port. The temporary socket object is then closed and
2833 deleted, and the port is returned. This method should only be used
2834 for obtaining an unused port in order to pass to an external program
2835 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2836 a parameter to a server-oriented class that doesn't give you direct
2837 access to the underlying socket used.
2838
2839 Finally, test_support.HOST has been introduced, which should be used
2840 for the host argument of any relevant socket calls (i.e. bind and
2841 connect).

3115Core and builtins
3116-----------------
3117
Fred Drakea8ee94b2008-03-01 02:45:07 +00003118- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003119 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003120
Georg Brandlad61bc82008-02-23 15:11:18 +00003121- Issue #2067: file.__exit__() now calls subclasses' close() method.
3122
3123- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003124
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003125- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003126 issue 215555 for a discussion.
3127
Eric Smitha73fbe72008-02-23 03:09:44 +00003128- Added the future_builtins module, which contains hex() and oct().
3129 These are the PEP 3127 version of these functions, designed to be
3130 compatible with the hex() and oct() builtins from Python 3.0. They
3131 differ slightly in their output formats from the existing, unchanged
3132 Python 2.6 builtins. The expected usage of the future_builtins
3133 module is:
3134 from future_builtins import hex, oct
3135
Eric Smith7ef40bf2008-02-20 23:34:22 +00003136- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3137 exponents for exponents with absolute value < 100. Follows C99
3138 standard. This is a change on Windows, which would use 3 digits.
3139 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3140 so that any alterations it does to the resulting string will be
3141 available in stringlib/formatter.h (for float.__format__).
3142
Eric Smith5a3c1352008-02-19 13:21:56 +00003143- Implemented PEP 3101, Advanced String Formatting. This adds a new
3144 builtin format(); a format() method for str and unicode; a
3145 __format__() method to object, str, unicode, int, long, float, and
3146 datetime; the class string.Formatter; and the C API
3147 PyObject_Format().
3148
Georg Brandl3ee81df2008-05-17 18:14:43 +00003149- Fixed several potential crashes, all caused by specially crafted
3150 __del__ methods exploiting objects in temporarily inconsistent
3151 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003152
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003153- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003154 prevent a possible crash: an Abstract Base Class would try to access
3155 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003156
Georg Brandl3ee81df2008-05-17 18:14:43 +00003157- Fixed repr() and str() of complex numbers with infinity or nan as
3158 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003159
Georg Brandl3ee81df2008-05-17 18:14:43 +00003160- Clear all free lists during a gc.collect() of the highest generation
3161 in order to allow pymalloc to free more arenas. Python may give back
3162 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003163
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164- Issue #2045: Fix an infinite recursion triggered when printing a
3165 subclass of collections.defaultdict, if its default_factory is set
3166 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003167
Christian Heimesf75dbef2008-02-08 00:11:31 +00003168- Fixed a minor memory leak in dictobject.c. The content of the free
3169 list was not freed on interpreter shutdown.
3170
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171- Limit free list of method and builtin function objects to 256
3172 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003173
Georg Brandl3ee81df2008-05-17 18:14:43 +00003174- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3175 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003176 to compact the internal free lists of pre-allocted ints and floats.
3177
Georg Brandl3ee81df2008-05-17 18:14:43 +00003178- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3179 calls. Python expected the return type int but the fork familie
3180 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3183 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3186 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003187
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3189 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003190
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3192 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003193
Georg Brandl3ee81df2008-05-17 18:14:43 +00003194- Patch #1473257: generator objects gain a gi_code attribute. This is
3195 the same object as the func_code attribute of the function that
3196 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003197
Georg Brandl3ee81df2008-05-17 18:14:43 +00003198- Issue #1920: "while 0" statements were completely removed by the
3199 compiler, even in the presence of an "else" clause, which is
3200 supposed to be run when the condition is false. Now the compiler
3201 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003202
Guido van Rossumeead05f2008-01-24 18:21:02 +00003203- A few crashers fixed: weakref_in_del.py (issue #1377858);
3204 loosing_dict_ref.py (issue #1303614, test67.py);
3205 borrowed_ref_[34].py (not in tracker).
3206
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003207- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003208 suppressed while an extension is loaded by calling SetErrorMode in
3209 dynload_win.c. The error is still reported properly.
3210
Georg Brandl3ee81df2008-05-17 18:14:43 +00003211- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003212 several extension methods and modules do not work without unicode
3213 support.
3214
Georg Brandl26543b12008-01-21 18:36:51 +00003215- Issue #1882: when compiling code from a string, encoding cookies in the
3216 second line of code were not always recognized correctly.
3217
Georg Brandl14404b62008-01-19 19:27:05 +00003218- Issue #1679: "0x" was taken as a valid integer literal.
3219
Georg Brandl6caad7d2008-01-26 14:19:22 +00003220- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003221 added.
3222
Christian Heimesc94e2b52008-01-14 04:13:37 +00003223- sys.float_info / PyFloat_GetInfo: The floating point information
3224 object was converted from a dict to a specialized structseq object.
3225
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226- Patch #1816: Added sys.flags structseq. It exposes the status of
3227 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003228
Georg Brandl3ee81df2008-05-17 18:14:43 +00003229- Objects/structseq.c: Implemented new structseq representation. The
3230 patch makes structseqs (e.g. the return value of os.stat) more
3231 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003232
Georg Brandl3ee81df2008-05-17 18:14:43 +00003233- Patch #1700288: added a type attribute cache that caches method
3234 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003235
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003236- Bug #1776: __import__() no longer accepts filenames on any platform.
3237 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003238
Georg Brandlaed6c662008-01-07 17:25:53 +00003239- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3240
Georg Brandl3ee81df2008-05-17 18:14:43 +00003241- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3242 envvar and sys.dont_write_bytecode attribute. All these can be set
3243 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003244
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245- Improve some exception messages when Windows fails to load an
3246 extension module. Now we get for example '%1 is not a valid Win32
3247 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003248
Georg Brandl3ee81df2008-05-17 18:14:43 +00003249- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003251- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3252 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003253
Christian Heimes0a8143f2007-12-18 23:22:54 +00003254- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003255 and INF. float("nan"), float("inf") and float("-inf") now work on
3256 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003257
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258- Compiler now generates simpler and faster code for dictionary
3259 literals. The oparg for BUILD_MAP now indicates an estimated
3260 dictionary size. There is a new opcode, STORE_MAP, for adding
3261 entries to the dictionary.

3279 running, and if the deallocation of its frames somehow calls the
3280 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003281

Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Issue #1265: Fix a problem with sys.settrace, if the tracing
3296 function uses a generator expression when at the same time the
3297 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003298
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003299- sets and frozensets now have an isdisjoint() method.
3300
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003301- optimize the performance of builtin.sum().
3302
Neal Norwitz44f326e2007-10-05 05:29:17 +00003303- Fix warnings found by the new version of the Coverity checker.
3304
Georg Brandl3ee81df2008-05-17 18:14:43 +00003305- The enumerate() builtin function is no longer bounded to sequences
3306 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3307 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003308
Georg Brandl3ee81df2008-05-17 18:14:43 +00003309- Issue #1686386: Tuple's tp_repr did not take into account the
3310 possibility of having a self-referential tuple, which is possible
3311 from C code. Nor did object's tp_str consider that a type's tp_str
3312 could do something that could lead to an inifinite recursion.
3313 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3314 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003315
Georg Brandl3ee81df2008-05-17 18:14:43 +00003316- Issue #1164: It was possible to trigger deadlock when using the
3317 'print' statement to write to a file since the GIL was not released
3318 as needed. Now PyObject_Print() does the right thing along with
3319 various tp_print implementations of the built-in types and those in
3320 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003322- Issue #1147: Exceptions were directly allowing string exceptions in
3323 their throw() method even though string exceptions no longer
3324 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003325
Georg Brandl3ee81df2008-05-17 18:14:43 +00003326- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003329- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003330 PyObject_Call() never calling back out to Python code to trigger
3331 recursion depth updates/checks. Required the creation of a static
3332 RuntimeError instance in case normalizing an exception put the
3333 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00003349- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003350 __*__ attributes. (Some already existed, e.g., __doc__ and
3351 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003352
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003353- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00003360 "except E as target:". This is to provide forwards compatibility
3361 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003362
Brett Cannon229cee22007-05-05 01:34:02 +00003363- Deprecate BaseException.message as per PEP 352.

3381
Guido van Rossum143b5642007-03-23 04:58:42 +00003382- Bug #1683368: The object.__init__() and object.__new__() methods are
3383 now stricter in rejecting excess arguments. The only time when
3384 either allows excess arguments is when it is not overridden and the
3385 other one is. For backwards compatibility, when both are
3386 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003387 warning later). Also, type.__init__() insists on the same signature
3388 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003389
Georg Brandl3ee81df2008-05-17 18:14:43 +00003390- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3391 object to complex using its __complex__() method before falling back
3392 to the __float__() method. Therefore, the functions in the cmath
3393 module now can operate on objects that define a __complex__()
3394 method.

3411
Georg Brandl7b9c5552007-03-12 14:30:05 +00003412- Bug #1678647: write a newline after printing an exception in any
3413 case, even when converting the value to a string failed.
3414
Georg Brandl871f1bc2007-03-12 13:17:36 +00003415- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003416 its argument, if it exists. If not, it will work like before. This
3417 allows customizing the output of dir() in the presence of a
3418 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003419
Collin Winter276887b2007-03-12 16:11:39 +00003420- Patch #922167: Python no longer segfaults when faced with infinitely
3421 self-recursive reload() calls (as reported by bug #742342).
3422

3427 parthensized forms. This means complex(repr(x)) now works instead of
3428 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003429
Georg Brandlaa2321b2007-03-07 00:40:28 +00003430- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431 makes the filenames the warning module prints much more sensible
3432 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003433

Georg Brandl0fca97a2007-03-05 22:28:08 +00003445- Patch #1674228: when assigning a slice (old-style), check for the
3446 sq_ass_slice instead of the sq_slice slot.
3447
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448- When printing an unraisable error, don't print exceptions. before
3449 the name. This duplicates the behavior whening normally printing
3450 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004074- unittest now verifies more of its assumptions. In particular,
4075 TestCase and TestSuite subclasses (not instances) are no longer
4076 accepted in TestSuite.addTest(). This should cause no
4077 incompatibility since it never made sense with ordinary subclasses
4078 -- the failure just occurred later, with a more cumbersome
4079 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004360- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4361 with RFC 3207 and forgets any knowledge obtained from the server not
4362 obtained from the TLS negotiation itself. Patch contributed by Bill
4363 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004364
Georg Brandl3ee81df2008-05-17 18:14:43 +00004365- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004366 that the SMTP.starttls() caller no longer needs to call ehlo()
4367 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004368 does not claim to support starttls. Adds the
4369 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4450 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4451 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004468 time so that opening a database previously created with the DB_DUP
4469 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4470 opens. Specifically: dictionary assignment to a DB object will
4471 replace all values for a given key when the database allows
4472 duplicate values. DB users should use DB.put(k, v) when they want
4473 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004474

4480 characters with ASCII value less than 32. Also, it correctly quotes
4481 dots only if they occur on a single line, as opposed to the previous
4482 behavior of quoting dots if they are the second character of any
4483 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004484

Georg Brandl3ee81df2008-05-17 18:14:43 +00004813- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4814 to ``PyTuple_SetItem``, it can be used to populate a brand new
4815 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004819- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4820 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4821 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004822
4823- Patch #1720595: add T_BOOL to the range of structmember types.
4824
4825- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4826 ``PyFloat_GetInfo()`` to the float API.
4827
Georg Brandl3ee81df2008-05-17 18:14:43 +00004828- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4829 of w# format code incorrectly truncated the length to an int, even
4830 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4831 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004832
Georg Brandl3ee81df2008-05-17 18:14:43 +00004833- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4834 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004836- PEP 3123: Provide forward compatibility with Python 3.0, while
4837 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4838 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004839
Georg Brandl3ee81df2008-05-17 18:14:43 +00004840- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4841 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004842
4843- Patch #1733960: Allow T_LONGLONG to accept ints.
4844
4845- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4846
Christian Heimes000a0742008-01-03 22:16:32 +00004847- Added a new API function ``PyImport_ImportModuleNoBlock``.
4848
Georg Brandl6caad7d2008-01-26 14:19:22 +00004849- Bug #1637022: Prefix AST symbols with _Py_.
4850
4851- Fix some leftovers from the conversion from int to Py_ssize_t
4852 (relevant to strings and sequences of more than 2**31 items).
4853
4854- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4855 outside of pystate.c and should not be necessary.
4856
Georg Brandl3ee81df2008-05-17 18:14:43 +00004857- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4858 absolute imports. In earlier versions they might have used relative
4859 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004860
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4862 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004863
Georg Brandl3ee81df2008-05-17 18:14:43 +00004864- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4865 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004871- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4872 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4873 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4874 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004875

Georg Brandl3ee81df2008-05-17 18:14:43 +00004889- Removed the macfs module. It had been deprecated since Python 2.5.
4890 This lead to the deprecation of macostools.touched() as it relied
4891 solely on macfs and was a no-op under OS X.
