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 Dickinson18cfada2009-11-23 18:46:41 +000015- Remove restrictions on precision when formatting floats. E.g.,
16 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
17 requested 120 significant digits instead.
18
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000019- Add Py3k warnings for parameter names in parenthesis.
20
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000021- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000022
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000023- Issue #7085: Fix crash when importing some extensions in a thread
24 on MacOSX 10.6.
25
Mark Dickinsonb678de82009-11-19 18:41:49 +000026- Issue #7117: repr(x) for a float x returns a result based on the
27 shortest decimal string that's guaranteed to round back to x under
28 correct rounding (with round-half-to-even rounding mode).
29 Previously it gave a string based on rounding x to 17 decimal digits.
30 repr(x) for a complex number behaves similarly. On platforms where
31 the correctly-rounded strtod and dtoa code is not supported (see below),
32 repr is unchanged.
33
34- Issue #7117: On almost all platforms: float-to-string and
35 string-to-float conversions within Python are now correctly rounded.
36 Places these conversions occur include: str for floats and complex
37 numbers; the float and complex constructors; old-style and new-style
38 numeric formatting; serialization and deserialization of floats and
39 complex numbers using marshal, pickle and json; parsing of float and
40 imaginary literals in Python code; Decimal-to-float conversion.
41
42 The conversions use a Python-adapted version of David Gay's
43 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
44 functions. This code is supported on Windows, and on Unix-like
45 platforms using gcc, icc or suncc as the C compiler. There may be a
46 small number of platforms on which correct operation of this code
47 cannot be guaranteed, so the code is not used: notably, this applies
48 to platforms where the C double format is not IEEE 754 binary64, and
49 to platforms on x86 hardware where the x87 FPU is set to 64-bit
50 precision and Python's configure script is unable to determine how
51 to change the FPU precision. On these platforms conversions use the
52 platform strtod and dtoa, as before.
53
Mark Dickinsonbd15a062009-11-18 19:33:35 +000054- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +000055 now uses the correctly-rounded string <-> float conversions
56 described above (when available), and so produces correctly rounded
57 results that will display nicely under the float repr. There are
58 two related small changes: (1) round now accepts any class with an
59 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +000060 floats for the second argument), and (2) an excessively large second
61 integer argument (e.g., round(1.234, 10**100)) no longer raises an
62 exception.
63
Philip Jenveyfab8be22009-11-17 02:42:26 +000064- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
65
Benjamin Petersone36199b2009-11-12 23:39:44 +000066- Fix several issues with compile(). The input can now contain Windows and Mac
67 newlines and is no longer required to end in a newline.
68
Mark Dickinsonc04c7c52009-10-26 22:28:14 +000069- Remove length limitation when constructing a complex number from a
70 unicode string.
71
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +000072- Issue #7244: itertools.izip_longest() no longer ignores exceptions
73 raised during the formation of an output tuple.
74

76
Antoine Pitrouefb60c02009-10-20 21:29:37 +000077- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
78 fixes the problem of some exceptions being thrown at shutdown when the
79 interpreter is killed. Patch by Adam Olsen.
80
Eric Smithc12781a2009-10-19 14:38:14 +000081- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

88 is the only object holding a reference to it.
89
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +000090- Issue #1754094: Improve the stack depth calculation in the compiler.
91 There should be no other effect than a small decrease in memory use.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000190- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
191 statement and correctly lookup the __enter__ and __exit__ special methods.
192
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000193- Issue #5829: complex("1e500") no longer raises OverflowError. This
194 makes it consistent with float("1e500") and interpretation of real
195 and imaginary literals.
196
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000197- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

203
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000204- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
205 (1) inf and nan strings with trailing whitespace were incorrectly
206 rejected; (2) parsing of strings representing infinities and nans
207 was locale aware; and (3) the interpretation of fromhex('-nan')
208 didn't match that of float('-nan').
209
Eric Smitha985a3a2009-05-05 18:26:08 +0000210- Issue #5920: For float.__format__, change the behavior with the
211 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
212 to be like 'g' but with at least one decimal point and with a
213 default precision of 12. Previously, the behavior the same but with
214 a default precision of 6. This more closely matches str(), and
215 reduces surprises when adding alignment flags to the empty
216 presentation type. This also affects the new complex.__format__ in
217 the same way.
218
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000219- Issue #5890: in subclasses of 'property' the __doc__ attribute was
220 shadowed by classtype's, even if it was None. property now
221 inserts the __doc__ into the subclass instance __dict__.
222
Antoine Pitrou653dece2009-05-04 18:32:32 +0000223- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

236 titlecase, but not their own uppercase.
237
Eric Smith068f0652009-04-25 21:40:15 +0000238- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
239 _PyOS_double_to_string or PyOS_double_to_string.
240

242
Mark Dickinson95bc9802009-04-24 12:46:53 +0000243- Issue #5816: complex(repr(z)) now recovers z exactly, even when
244 z involves nans, infs or negative zeros.
245
Eric Smithaca19e62009-04-22 13:29:05 +0000246- Implement PEP 378, Format Specifier for Thousands Separator, for
247 floats, ints, and longs.
248
249- Issue #5515: 'n' formatting for ints, longs, and floats handles
250 leading zero formatting poorly.
251
252- Issue #5772: For float.__format__, don't add a trailing ".0" if
253 we're using no type code and we have an exponent.
254

260
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000261- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000262 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000263
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000264- Issue #5759: float() didn't call __float__ on str subclasses.
265
Georg Brandl3c4a5462009-04-12 12:08:12 +0000266- Issue #5704: the "-3" command-line option now implies "-t".

279 the end sys.path, for compatibility with the system install of Python.
280
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000281- Issue #4688: Add a heuristic so that tuples and dicts containing only
282 untrackable objects are not tracked by the garbage collector. This can
283 reduce the size of collections and therefore the garbage collection overhead
284 on long-running programs, depending on their particular use of datatypes.
285
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000286- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
287 improve its performance. Long divisions and remainder operations
288 are now between 50% and 150% faster.
289
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000290- Issue #4258: Make it possible to use base 2**30 instead of base
291 2**15 for the internal representation of integers, for performance
292 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
293 --enable-big-digits option to configure, which overrides the
294 default. Add sys.long_info structseq to provide information about
295 the internal format.
296
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000297- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
298 result traceback.__members__ no longer exists.)
299
Mark Dickinson6b265f12009-03-18 16:07:26 +0000300- Issue #4474: PyUnicode_FromWideChar now converts characters outside
301 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
302 and sizeof(Py_UNICODE) == 2.
303
Eric Smith6f42edb2009-03-14 11:57:26 +0000304- Issue #5237: Allow auto-numbered fields in str.format(). For
305 example: '{} {}'.format(1, 2) == '1 2'.

Brett Cannon6c4cff02009-03-11 04:51:06 +0000307- Issue #3652: Make the 'line' argument for warnings.showwarning() a
308 requirement. Means the DeprecationWarning from Python 2.6 can go away.
309
Eric Smithe9fb6862009-02-20 14:02:36 +0000310- Issue #5247: Improve error message when unknown format codes are
311 used when using str.format() with str, unicode, long, int, and
312 float arguments.
313
Raymond Hettinger08259e82009-02-18 23:10:19 +0000314- Running Python with the -3 option now also warns about classic division
315 for ints and longs.
316
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000317- Issue #5260: Long integers now consume less memory: average
318 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
319 on a 64-bit system.
320
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000321- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

Benjamin Petersone18ef192009-01-20 14:21:16 +0000327- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
328
Georg Brandl29c6a282009-04-05 20:23:13 +0000329- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000330 were suppressing all exceptions. These include list(), filter(), map(),
331 zip(), and bytearray().
332
Benjamin Peterson596d3062009-01-19 15:42:23 +0000333- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
334 functions.

340
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000341- Issue #4935: The overflow checking code in the expandtabs() method common
342 to str, bytes and bytearray could be optimized away by the compiler, letting
343 the interpreter segfault instead of raising an error.
344
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000345- Issue #3720: Fix a crash when an iterator modifies its class and removes its

351
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000352- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
353 collecting the oldest generation) so that allocating lots of objects without
354 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000355 Martin von Löwis at

359
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000360- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
361 an existing .py counterpart, override the co_filename attributes of all
362 code objects if the original filename is obsolete (which can happen if the
363 file has been renamed, moved, or if it is accessed through different paths).
364 Patch by Ziga Seilnacht and Jean-Paul Calderone.
365
Martin v. Löwis5344c992009-01-02 20:32:55 +0000366- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000368- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
369 file with `str' filename on Windows.
370
Antoine Pitrouaa687902009-01-01 14:11:22 +0000371- Issue #3680: Reference cycles created through a dict, set or deque iterator
372 did not get collected.
373
Nick Coghlan180e4002008-12-30 01:18:48 +0000374- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
375 where the tp_hash and tp_dict slots are both NULL.
376
Benjamin Peterson7af65562008-12-29 17:56:58 +0000377- Issue #4764: With io.open, IOError.filename is set when trying to open a
378 directory on POSIX systems.
379
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000380- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
381 systems.

Georg Brandl6425a2f2008-12-28 11:54:53 +0000383- Issue #4759: None is now allowed as the first argument of
384 bytearray.translate(). It was always allowed for bytes.translate().
385
Skip Montanarof205c132008-12-23 03:30:15 +0000386- Added test case to ensure attempts to read from a file opened for writing
387 fail.
388
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000389- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

399 context manager returns a value that cannot be converted to a bool.
400
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000401- Issue #4597: Fixed several opcodes that weren't always propagating
402 exceptions.
403
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000404- Issue #4445: Replace "sizeof(PyStringObject)" with
405 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
406 str instances. On a typical machine this saves 3 bytes of memory
407 (on average) per string allocation.
408
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000409- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
410 interpreter to abort ("Fatal Python error: Could not reset the stack!")
411 instead of throwing a MemoryError.
412
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000413- Issue #3689: The list reversed iterator now supports __length_hint__
414 instead of __len__. Behavior now matches other reversed iterators.
415
Benjamin Petersonc078f922008-11-21 22:27:24 +0000416- Issue #4367: Python would segfault during compiling when the unicodedata
417 module couldn't be imported and \N escapes were present.
418
Vinay Sajip213faca2008-12-03 23:22:58 +0000419- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000420 method on file objects with closefd=False. The file descriptor is still
421 kept open but the file object behaves like a closed file. The ``FileIO``
422 object also got a new readonly attribute ``closefd``.
423
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000424- Issue #4348: Some bytearray methods returned that didn't cause any change to
425 the bytearray, returned the same bytearray instead of a copy.
426
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000427- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
428
Benjamin Peterson273c2332008-11-17 22:39:09 +0000429- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.

Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000431- Issue #4048: The parser module now correctly validates relative imports.
432
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000433- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
434 exec statement.
435
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000436- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
437 method does not return iterators for the 4th and 5th items.
438
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000439- Issue #4209: Enabling unicode_literals and the print_function in the same
440 __future__ import didn't work.
441
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000442- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000443 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000444
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000445- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
446 returned a path longer than MAX_PATH. (But It's doubtful this code path is
447 really executed because I cannot move to such directory on win2k)
448
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000449- Issue #4069: When set.remove(element) is used with a set element, the element
450 is temporarily replaced with an equivalent frozenset. But the eventual
451 KeyError would always report the empty frozenset([]) as the missing key. Now
452 it correctly refers to the initial element.
453
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000454- Issue #4509: Various issues surrounding resize of bytearray objects to
455 which there are buffer exports.
456

465
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000466- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
467 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000469- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
470 returned them on 64bit platforms.
471
Walter Dörwalded960ac2009-05-03 22:36:33 +0000472- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
473 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
474 step. This avoids problems with counting UTF-8 bytes that ignores the effect
475 of using the replace error handler in PyUnicode_DecodeUTF8().
476
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000477- Issue #3739: The unicode-internal encoder now reports the number of characters
478 consumed like any other encoder (instead of the number of bytes).

507
Nick Coghlan49868cb2009-11-15 07:30:34 +0000508- Issue #6816: runpy now provides a run_path function that allows Python code
509 to execute file paths that refer to source or compiled Python files as well
510 as zipfiles, directories and other valid sys.path entries that contain a
511 __main__.py file. This allows applications that run other Python scripts to
512 support the same flexibility as the CPython command line itself.

Antoine Pitrouc562ca42009-11-13 22:31:18 +0000514- Issue #7318: multiprocessing now uses a timeout when it fails to establish

1811
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001812- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1813 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1814 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1815 ``printf`` function, whereas PyString_FromFormat has an independent
1816 implementation and uses "%zd" on all platforms for size_t values.
1817 This makes a difference on win64, where ``printf`` needs "%Id" to display
1818 64bit values.

1824 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001835 was correctly parsed but parsing of subsequent arguments failed.
1836
Vinay Sajip35e3b032008-09-01 14:33:59 +00001837- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001838 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1839 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1840 when given a tuple of classes as second argument, were looking up
1841 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1842 type object.

1987-----------------
1988
Guido van Rossumf8402962008-08-20 15:01:50 +00001989- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1990 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1991 extensions do not automatically benefit from the class attribute
1992 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1993 to their tp_flags field if they care. This is a backwards
1994 compatibility feature; in 3.0, all types will use the cache by
1995 default.

Benjamin Petersonf647dc12008-08-20 01:27:30 +00001997- Keyword arguments can now follow starred arguments. (``f(a, *args,
1998 keyword=23)`` is now valid syntax.)
1999
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002000- ctypes function pointers that are COM methods have a boolean True
2001 value again.
2002
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002003- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2004 by denying s# to parse objects that have a releasebuffer procedure,
2005 and introducing s*.
2006
Georg Brandl1e13ea92008-08-11 09:07:59 +00002007- Issue #3537: Fix an assertion failure when an empty but presized dict
2008 object was stored in the freelist.
2009
Mark Dickinsonb6467572008-08-04 21:30:09 +00002010- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2011 ValueError consistently across platforms.
2012
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002013- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2014 (64bit Unix, for example), unichr() would truncate its argument and return
2015 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2016
Neal Norwitze7d8be82008-07-31 17:17:14 +00002017- Apply security patches from Apple.
2018
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002019- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2020 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2021
Antoine Pitrou92f82162008-07-25 22:22:08 +00002022- Issue #1819: function calls with several named parameters are now on
2023 average 35% faster (as measured by pybench).
2024
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002025- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2026 the python debugger steps into a class statement: the free variables (local
2027 variables defined in an outer scope) would be deleted from the outer scope.
2028
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002029- Issue #2620: Overflow checking when allocating or reallocating memory
2030 was not always being done properly in some python types and extension
2031 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2032 all been updated to perform better checks and places in the code that
2033 would previously leak memory on the error path when such an allocation
2034 failed have been fixed.

2040
Benjamin Petersone977ad42008-08-20 01:42:01 +00002041- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2042 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2043
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002044- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2045 version reported by these tools does not necessarily follow the python
2046 version numbering scheme, so the module is less strict when parsing it.
2047
Nick Coghlanf70385a2008-08-18 12:42:46 +00002048- Issue #2235: Added Py3k warnings for types which will become unhashable
2049 under the stricter __hash__ inheritance rules in 3.0. Several types
2050 which did not meet the rules for hash invariants and were already
2051 unhashable in 3.0 have now been explicitly flagged as unhashable in
2052 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2053 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2054
Brett Cannon88f801d2008-08-18 00:46:22 +00002055- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2056 imported into the module but exposed as part of the module's API.
2057

2063
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002064- Issue #3575: Incremental decoder's decode function now takes bytearray
2065 by using 's*' instead of 't#'.
2066
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002067- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002068 fails unicode conversion on 2nd parameter. (windows only)
2069
Facundo Batista94f243a2008-08-17 03:38:39 +00002070- Issue 2464. urllib2 now supports a malformation in the URL received
2071 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +00002075
Facundo Batistaeb90b782008-08-16 14:44:07 +00002076- Issue #2776: fixed small issue when handling an URL with double slash
2077 after a 302 response in the case of not going through a proxy.
2078
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002079- Issue #2676: in the email package, content-type parsing was hanging on
2080 pathological input because of quadratic or exponential behaviour of a
2081 regular expression.
2082
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002083- Issue #3476: binary buffered reading through the new "io" library is now
2084 thread-safe.
2085
Brett Cannonbf3157b2008-08-14 05:00:03 +00002086- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2087 since mimetools itself is deprecated. Because modules are cached, all
2088 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2089
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002090- Issue #3134: shutil referenced undefined WindowsError symbol.
2091
Robert Schuppenies14646332008-08-10 11:01:53 +00002092- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2093 menu entries were not deleted.
2094
Brett Cannon83e81842008-08-09 23:30:55 +00002095- Copied the implementation of reduce() to _functools.reduce() to have a
2096 version that did not raise a DeprecationWarning under -3.
2097
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002098- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2099 a MemoryError rather than silently stop the iteration.
2100
Guido van Rossum59ce9012008-08-09 14:55:34 +00002101- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2102 to _sre.compile() will now be rejected. This should not affect anybody
2103 since the re.compile() function never generates invalid re-bytecode.
2104
Skip Montanaroa032bf42008-08-08 22:52:51 +00002105- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2106 upon first access it can be automatically initialized from the csv file if
2107 it wasn't initialized during instantiation.
2108
Brett Cannon3aa2a492008-08-06 22:28:09 +00002109- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2110 the reload() built-in has been removed.
2111
Brett Cannon7e30b672008-08-04 21:52:25 +00002112- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002113 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2121 raised an AttributeError.
2122
Benjamin Peterson01a24322008-07-28 23:35:27 +00002123- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002124 asking for a specific length. This problem only affected files opened
2125 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002126
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002127- Issue #3449: Update decimal module to use most recent specification
2128 (v. 1.68) and tests (v. 2.58) from IBM.
2129

2149
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002150- Issue #3394: zipfile.writestr sets external attributes when passed a
2151 file name rather than a ZipInfo instance, so files are extracted with
2152 mode 0600 rather than 000 under Unix.
2153
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002154- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2155 argument in python 2.5, this broke code that subclassed Popen to include its
2156 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2164-------------
2165
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002166- Issue #2235: the C API function PyObject_HashNotImplemented and its
2167 interaction with the tp_hash slot (added in 2.6b2) are now documented
2168
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002169- Issue #643841: The language reference now provides more detailed
2170 coverage of the lookup process for special methods. The disclaimers
2171 regarding lack of coverage of new-style classes have also been
2172 removed, since the coverage is now fairly reasonable.

2176================================
2177
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002178*Release date: 17-Jul-2008*
2179
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002180Core and Builtins
2181-----------------
2182
Georg Brandl3e483f62008-07-16 22:57:41 +00002183- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2184 its methods now allow for items objects that can be converted to
2185 an integer using operator.index().
2186
Mark Dickinson64b7e502008-07-16 09:40:03 +00002187- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2188 produced a ValueError instead of giving the correct float.
2189
Eric Smitha5fa5a22008-07-16 00:11:49 +00002190- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2191 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2192
Mark Dickinson7103aa42008-07-15 19:08:33 +00002193- Issue #3008: the float type has a new instance method 'float.hex'
2194 and a new class method 'float.fromhex' to convert floating-point
2195 numbers to and from hexadecimal strings, respectively.
2196
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002197- Issue #2235: __hash__ is once again inherited by default. To allow
2198 collections.Hashable to remain meaningful in the presence of the
2199 default hash implementation (object.__hash__), it is now possible
2200 to explicit block inheritance of hash by setting __hash__=None at
2201 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2202 level.
2203
Nick Coghlanb028f502008-07-13 14:52:36 +00002204- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2205 the parent module cannot be found while performing an absolute import.
2206 This means that an incorrectly defined __package__ attribute will
2207 now only prevent relative imports in that module rather than causing
2208 all imports from that module to fail.
2209
Nick Coghlan14ff9942008-07-08 14:21:42 +00002210- Issue #2517: Allow unicode messages in Exceptions again by correctly
2211 bypassing the instance dictionary when looking up __unicode__ on
2212 new-style classes.
2213
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002214- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2215 set to a custom object whose write() method happens to install
2216 another file in sys.stdout.
2217
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002218- Issue #3088: Corrected a race condition in classes derived from
2219 threading.local: the first member set by a thread could be saved in
2220 another thread's dictionary.
2221
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002222- Issue #3004: Minor change to slice.indices(): the start and stop
2223 arguments are now treated identically, making the behaviour easier
2224 to describe and understand. For example, slice(None, -10,
2225 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2226 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2227 10, -1).
2228
Georg Brandl278fc502008-07-19 12:46:12 +00002229- Issue #3219: Calling a function with repeated keyword arguments,
2230 f(a=2, a=23), would not cause a syntax error. This was a regression
2231 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002232
Georg Brandl278fc502008-07-19 12:46:12 +00002233- Issue #2862: Make int and float freelist management consistent with
2234 other freelists. Changes their CompactFreeList apis into
2235 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002236

2238-------
2239
Thomas Heller57adf222008-08-14 19:10:48 +00002240- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2241 api functions without holding the GIL, which could lead to a fatal
2242 error when they failed.
2243
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002244- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2253 ForkingPickler.register() to resolve conflict with ctypes.
2254
Vinay Sajip51e65192008-07-18 09:01:10 +00002255- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002256
Thomas Heller880f5292008-07-15 19:39:38 +00002257- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2258 a valid dlerror() message.
2259
Thomas Heller2bad6572008-07-15 17:19:50 +00002260- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2261 incomplete structure was created.
2262
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002263- Issue #3339: dummy_thread.acquire() should not return None.
2264
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002265- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2266
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002267- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002268
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002269- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2270 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002271 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002272 content-length. The problem had been corrected in the 2.4 branch, but never
2273 merged into trunk.
2274
Georg Brandle78fbcc2008-07-05 10:13:36 +00002275- Issue #2663: add filtering capability to shutil.copytree().

2280
2281- Issue #1746: Correct handling of zipfile archive comments (previously
2282 archives with comments over 4k were flagged as invalid). Allow writing

2680 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002681 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002682
2683 This is controlled by the configure argument ``--with-universal-archs``:
2684
2685 - ``--with-universal-archs=all``: install 4-way universal
2686
2687 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2688
2689 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2690
2691 This option should be used in combination with ``--enable-universalsdk=``.
2692
2693 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 +00002743- Issue #1631171: Re-implement the 'warnings' module in C (the
2744 original Python code has been kept as backup). This will allow for
2745 using the 'warning's machinery in such places as the parser where
2746 use of pure Python code is not possible. Both the ``showarning()``
2747 and ``formatwarning()`` gain an optional 'line' argument which is
2748 not called by default for backwards-compatibility reasons. Setting
2749 ``warnings.showwarning()`` to an implementation that lacks support
2750 for the ``line`` argument will raise a DeprecationWarning.

2774
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002775- The getpass module has been improved on Unix. It now uses /dev/tty
2776 by default and uses stderr instead of stdout. A GetPassWarning is
2777 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002792- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002793 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002813- Issue #2550: The approach used by client/server code for obtaining
2814 ports to listen on in network-oriented tests has been refined in an
2815 effort to facilitate running multiple instances of the entire
2816 regression test suite in parallel without issue.
2817 test_support.bind_port() has been fixed such that it will always
2818 return a unique port -- which wasn't always the case with the
2819 previous implementation, especially if socket options had been set
2820 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2821 new implementation of bind_port() will actually raise an exception
2822 if it is passed an AF_INET/SOCK_STREAM socket with either the
2823 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2824 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2825 the socket it's been passed. This currently only applies to
2826 Windows. This option prevents any other sockets from binding to the
2827 host/port we've bound to, thus removing the possibility of the
2828 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2829 when a second SOCK_STREAM socket binds and accepts to a host/port
2830 that's already been bound by another socket. The optional preferred
2831 port parameter to bind_port() has been removed. Under no
2832 circumstances should tests be hard coding ports!
2833
2834 test_support.find_unused_port() has also been introduced, which will
2835 pass a temporary socket object to bind_port() in order to obtain an
2836 unused port. The temporary socket object is then closed and
2837 deleted, and the port is returned. This method should only be used
2838 for obtaining an unused port in order to pass to an external program
2839 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2840 a parameter to a server-oriented class that doesn't give you direct
2841 access to the underlying socket used.
2842
2843 Finally, test_support.HOST has been introduced, which should be used
2844 for the host argument of any relevant socket calls (i.e. bind and
2845 connect).

3119Core and builtins
3120-----------------
3121
Fred Drakea8ee94b2008-03-01 02:45:07 +00003122- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003123 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003124
Georg Brandlad61bc82008-02-23 15:11:18 +00003125- Issue #2067: file.__exit__() now calls subclasses' close() method.
3126
3127- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003128
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003129- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003130 issue 215555 for a discussion.
3131
Eric Smitha73fbe72008-02-23 03:09:44 +00003132- Added the future_builtins module, which contains hex() and oct().
3133 These are the PEP 3127 version of these functions, designed to be
3134 compatible with the hex() and oct() builtins from Python 3.0. They
3135 differ slightly in their output formats from the existing, unchanged
3136 Python 2.6 builtins. The expected usage of the future_builtins
3137 module is:
3138 from future_builtins import hex, oct
3139
Eric Smith7ef40bf2008-02-20 23:34:22 +00003140- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3141 exponents for exponents with absolute value < 100. Follows C99
3142 standard. This is a change on Windows, which would use 3 digits.
3143 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3144 so that any alterations it does to the resulting string will be
3145 available in stringlib/formatter.h (for float.__format__).
3146
Eric Smith5a3c1352008-02-19 13:21:56 +00003147- Implemented PEP 3101, Advanced String Formatting. This adds a new
3148 builtin format(); a format() method for str and unicode; a
3149 __format__() method to object, str, unicode, int, long, float, and
3150 datetime; the class string.Formatter; and the C API
3151 PyObject_Format().
3152
Georg Brandl3ee81df2008-05-17 18:14:43 +00003153- Fixed several potential crashes, all caused by specially crafted
3154 __del__ methods exploiting objects in temporarily inconsistent
3155 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003156
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003157- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003158 prevent a possible crash: an Abstract Base Class would try to access
3159 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003160
Georg Brandl3ee81df2008-05-17 18:14:43 +00003161- Fixed repr() and str() of complex numbers with infinity or nan as
3162 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003163
Georg Brandl3ee81df2008-05-17 18:14:43 +00003164- Clear all free lists during a gc.collect() of the highest generation
3165 in order to allow pymalloc to free more arenas. Python may give back
3166 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003167
Georg Brandl3ee81df2008-05-17 18:14:43 +00003168- Issue #2045: Fix an infinite recursion triggered when printing a
3169 subclass of collections.defaultdict, if its default_factory is set
3170 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003171
Christian Heimesf75dbef2008-02-08 00:11:31 +00003172- Fixed a minor memory leak in dictobject.c. The content of the free
3173 list was not freed on interpreter shutdown.
3174
Georg Brandl3ee81df2008-05-17 18:14:43 +00003175- Limit free list of method and builtin function objects to 256
3176 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003177
Georg Brandl3ee81df2008-05-17 18:14:43 +00003178- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3179 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003180 to compact the internal free lists of pre-allocted ints and floats.
3181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3183 calls. Python expected the return type int but the fork familie
3184 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003185
Georg Brandl3ee81df2008-05-17 18:14:43 +00003186- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3187 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003188
Georg Brandl3ee81df2008-05-17 18:14:43 +00003189- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3190 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003191
Georg Brandl3ee81df2008-05-17 18:14:43 +00003192- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3193 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003194
Georg Brandl3ee81df2008-05-17 18:14:43 +00003195- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3196 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003197
Georg Brandl3ee81df2008-05-17 18:14:43 +00003198- Patch #1473257: generator objects gain a gi_code attribute. This is
3199 the same object as the func_code attribute of the function that
3200 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003201
Georg Brandl3ee81df2008-05-17 18:14:43 +00003202- Issue #1920: "while 0" statements were completely removed by the
3203 compiler, even in the presence of an "else" clause, which is
3204 supposed to be run when the condition is false. Now the compiler
3205 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003206
Guido van Rossumeead05f2008-01-24 18:21:02 +00003207- A few crashers fixed: weakref_in_del.py (issue #1377858);
3208 loosing_dict_ref.py (issue #1303614, test67.py);
3209 borrowed_ref_[34].py (not in tracker).
3210
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003211- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003212 suppressed while an extension is loaded by calling SetErrorMode in
3213 dynload_win.c. The error is still reported properly.
3214
Georg Brandl3ee81df2008-05-17 18:14:43 +00003215- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003216 several extension methods and modules do not work without unicode
3217 support.
3218
Georg Brandl26543b12008-01-21 18:36:51 +00003219- Issue #1882: when compiling code from a string, encoding cookies in the
3220 second line of code were not always recognized correctly.
3221
Georg Brandl14404b62008-01-19 19:27:05 +00003222- Issue #1679: "0x" was taken as a valid integer literal.
3223
Georg Brandl6caad7d2008-01-26 14:19:22 +00003224- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003225 added.
3226
Christian Heimesc94e2b52008-01-14 04:13:37 +00003227- sys.float_info / PyFloat_GetInfo: The floating point information
3228 object was converted from a dict to a specialized structseq object.
3229
Georg Brandl3ee81df2008-05-17 18:14:43 +00003230- Patch #1816: Added sys.flags structseq. It exposes the status of
3231 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003232
Georg Brandl3ee81df2008-05-17 18:14:43 +00003233- Objects/structseq.c: Implemented new structseq representation. The
3234 patch makes structseqs (e.g. the return value of os.stat) more
3235 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003236
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237- Patch #1700288: added a type attribute cache that caches method
3238 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003239
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003240- Bug #1776: __import__() no longer accepts filenames on any platform.
3241 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003242
Georg Brandlaed6c662008-01-07 17:25:53 +00003243- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3244
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3246 envvar and sys.dont_write_bytecode attribute. All these can be set
3247 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003248
Georg Brandl3ee81df2008-05-17 18:14:43 +00003249- Improve some exception messages when Windows fails to load an
3250 extension module. Now we get for example '%1 is not a valid Win32
3251 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003252
Georg Brandl3ee81df2008-05-17 18:14:43 +00003253- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003255- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3256 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003257
Christian Heimes0a8143f2007-12-18 23:22:54 +00003258- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003259 and INF. float("nan"), float("inf") and float("-inf") now work on
3260 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003261
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262- Compiler now generates simpler and faster code for dictionary
3263 literals. The oparg for BUILD_MAP now indicates an estimated
3264 dictionary size. There is a new opcode, STORE_MAP, for adding
3265 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003266
Georg Brandl3ee81df2008-05-17 18:14:43 +00003267- Issue #1638: %zd configure test fails on Linux.

3280 __package__ attribute.
3281
Georg Brandl3ee81df2008-05-17 18:14:43 +00003282- Issue #1402: Fix a crash on exit, when another thread is still
3283 running, and if the deallocation of its frames somehow calls the
3284 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003285

3295 file can now be directly executed by passing their name to the
3296 interpreter. The directory/zipfile is automatically inserted as the
3297 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003298
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299- Issue #1265: Fix a problem with sys.settrace, if the tracing
3300 function uses a generator expression when at the same time the
3301 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003302
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003303- sets and frozensets now have an isdisjoint() method.
3304
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003305- optimize the performance of builtin.sum().
3306
Neal Norwitz44f326e2007-10-05 05:29:17 +00003307- Fix warnings found by the new version of the Coverity checker.
3308
Georg Brandl3ee81df2008-05-17 18:14:43 +00003309- The enumerate() builtin function is no longer bounded to sequences
3310 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3311 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003312
Georg Brandl3ee81df2008-05-17 18:14:43 +00003313- Issue #1686386: Tuple's tp_repr did not take into account the
3314 possibility of having a self-referential tuple, which is possible
3315 from C code. Nor did object's tp_str consider that a type's tp_str
3316 could do something that could lead to an inifinite recursion.
3317 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3318 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003319
Georg Brandl3ee81df2008-05-17 18:14:43 +00003320- Issue #1164: It was possible to trigger deadlock when using the
3321 'print' statement to write to a file since the GIL was not released
3322 as needed. Now PyObject_Print() does the right thing along with
3323 various tp_print implementations of the built-in types and those in
3324 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003326- Issue #1147: Exceptions were directly allowing string exceptions in
3327 their throw() method even though string exceptions no longer
3328 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003329
Georg Brandl3ee81df2008-05-17 18:14:43 +00003330- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003333- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003334 PyObject_Call() never calling back out to Python code to trigger
3335 recursion depth updates/checks. Required the creation of a static
3336 RuntimeError instance in case normalizing an exception put the
3337 recursion check value past its limit. Fixes crashers
3338 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003353- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003354 __*__ attributes. (Some already existed, e.g., __doc__ and
3355 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003356
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003357- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00003364 "except E as target:". This is to provide forwards compatibility
3365 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003366
Brett Cannon229cee22007-05-05 01:34:02 +00003367- Deprecate BaseException.message as per PEP 352.

3385
Guido van Rossum143b5642007-03-23 04:58:42 +00003386- Bug #1683368: The object.__init__() and object.__new__() methods are
3387 now stricter in rejecting excess arguments. The only time when
3388 either allows excess arguments is when it is not overridden and the
3389 other one is. For backwards compatibility, when both are
3390 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003391 warning later). Also, type.__init__() insists on the same signature
3392 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003393
Georg Brandl3ee81df2008-05-17 18:14:43 +00003394- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3395 object to complex using its __complex__() method before falling back
3396 to the __float__() method. Therefore, the functions in the cmath
3397 module now can operate on objects that define a __complex__()
3398 method.

3415
Georg Brandl7b9c5552007-03-12 14:30:05 +00003416- Bug #1678647: write a newline after printing an exception in any
3417 case, even when converting the value to a string failed.
3418
Georg Brandl871f1bc2007-03-12 13:17:36 +00003419- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003420 its argument, if it exists. If not, it will work like before. This
3421 allows customizing the output of dir() in the presence of a
3422 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003423
Collin Winter276887b2007-03-12 16:11:39 +00003424- Patch #922167: Python no longer segfaults when faced with infinitely
3425 self-recursive reload() calls (as reported by bug #742342).
3426

3432 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003433
Georg Brandlaa2321b2007-03-07 00:40:28 +00003434- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435 makes the filenames the warning module prints much more sensible
3436 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003437

Georg Brandl0fca97a2007-03-05 22:28:08 +00003449- Patch #1674228: when assigning a slice (old-style), check for the
3450 sq_ass_slice instead of the sq_slice slot.
3451
Georg Brandl3ee81df2008-05-17 18:14:43 +00003452- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004078- unittest now verifies more of its assumptions. In particular,
4079 TestCase and TestSuite subclasses (not instances) are no longer
4080 accepted in TestSuite.addTest(). This should cause no
4081 incompatibility since it never made sense with ordinary subclasses
4082 -- the failure just occurred later, with a more cumbersome
4083 exception.

4362 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004363
Georg Brandl3ee81df2008-05-17 18:14:43 +00004364- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4365 with RFC 3207 and forgets any knowledge obtained from the server not
4366 obtained from the TLS negotiation itself. Patch contributed by Bill
4367 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004368
Georg Brandl3ee81df2008-05-17 18:14:43 +00004369- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004370 that the SMTP.starttls() caller no longer needs to call ehlo()
4371 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004372 does not claim to support starttls. Adds the
4373 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4454 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4455 silently miscode subclasses of those types. Now, it raises a
4456 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004457

Georg Brandl3ee81df2008-05-17 18:14:43 +00004472 time so that opening a database previously created with the DB_DUP
4473 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4474 opens. Specifically: dictionary assignment to a DB object will
4475 replace all values for a given key when the database allows
4476 duplicate values. DB users should use DB.put(k, v) when they want
4477 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004478

4484 characters with ASCII value less than 32. Also, it correctly quotes
4485 dots only if they occur on a single line, as opposed to the previous
4486 behavior of quoting dots if they are the second character of any
4487 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004488

Georg Brandl3ee81df2008-05-17 18:14:43 +00004817- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4818 to ``PyTuple_SetItem``, it can be used to populate a brand new
4819 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00004821- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004823- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4824 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4825 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004826
4827- Patch #1720595: add T_BOOL to the range of structmember types.
4828
4829- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4830 ``PyFloat_GetInfo()`` to the float API.
4831
Georg Brandl3ee81df2008-05-17 18:14:43 +00004832- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4833 of w# format code incorrectly truncated the length to an int, even
4834 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4835 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004836
Georg Brandl3ee81df2008-05-17 18:14:43 +00004837- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4838 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004839
Georg Brandl3ee81df2008-05-17 18:14:43 +00004840- PEP 3123: Provide forward compatibility with Python 3.0, while
4841 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4842 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004843
Georg Brandl3ee81df2008-05-17 18:14:43 +00004844- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4845 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004846
4847- Patch #1733960: Allow T_LONGLONG to accept ints.
4848
4849- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4850
Christian Heimes000a0742008-01-03 22:16:32 +00004851- Added a new API function ``PyImport_ImportModuleNoBlock``.
4852
Georg Brandl6caad7d2008-01-26 14:19:22 +00004853- Bug #1637022: Prefix AST symbols with _Py_.
4854
4855- Fix some leftovers from the conversion from int to Py_ssize_t
4856 (relevant to strings and sequences of more than 2**31 items).
4857
4858- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4859 outside of pystate.c and should not be necessary.
4860
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4862 absolute imports. In earlier versions they might have used relative
4863 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004864
Georg Brandl3ee81df2008-05-17 18:14:43 +00004865- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4866 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004867
Georg Brandl3ee81df2008-05-17 18:14:43 +00004868- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4869 macro so it can be used as an expression.

4874
Georg Brandl3ee81df2008-05-17 18:14:43 +00004875- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4876 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4877 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4878 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004879
Georg Brandl3ee81df2008-05-17 18:14:43 +00004880- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00004891- buildtools now raises a DeprecationWarning.
4892
Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Removed the macfs module. It had been deprecated since Python 2.5.
4894 This lead to the deprecation of macostools.touched() as it relied
4895 solely on macfs and was a no-op under OS X.
