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

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

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

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

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

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

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

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

283
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000284- Issue #4688: Add a heuristic so that tuples and dicts containing only
285 untrackable objects are not tracked by the garbage collector. This can
286 reduce the size of collections and therefore the garbage collection overhead
287 on long-running programs, depending on their particular use of datatypes.
288
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000289- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
290 improve its performance. Long divisions and remainder operations
291 are now between 50% and 150% faster.
292
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000293- Issue #4258: Make it possible to use base 2**30 instead of base
294 2**15 for the internal representation of integers, for performance
295 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
296 --enable-big-digits option to configure, which overrides the
297 default. Add sys.long_info structseq to provide information about
298 the internal format.
299
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000300- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
301 result traceback.__members__ no longer exists.)
302
Mark Dickinson6b265f12009-03-18 16:07:26 +0000303- Issue #4474: PyUnicode_FromWideChar now converts characters outside
304 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
305 and sizeof(Py_UNICODE) == 2.

309
Brett Cannon6c4cff02009-03-11 04:51:06 +0000310- Issue #3652: Make the 'line' argument for warnings.showwarning() a
311 requirement. Means the DeprecationWarning from Python 2.6 can go away.
312
Eric Smithe9fb6862009-02-20 14:02:36 +0000313- Issue #5247: Improve error message when unknown format codes are
314 used when using str.format() with str, unicode, long, int, and
315 float arguments.
316
Raymond Hettinger08259e82009-02-18 23:10:19 +0000317- Running Python with the -3 option now also warns about classic division
318 for ints and longs.
319
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000320- Issue #5260: Long integers now consume less memory: average

Benjamin Petersone18ef192009-01-20 14:21:16 +0000330- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
331
Georg Brandl29c6a282009-04-05 20:23:13 +0000332- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000333 were suppressing all exceptions. These include list(), filter(), map(),
334 zip(), and bytearray().
335
Benjamin Peterson596d3062009-01-19 15:42:23 +0000336- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

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

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

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

Nick Coghlan180e4002008-12-30 01:18:48 +0000377- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
378 where the tp_hash and tp_dict slots are both NULL.
379
Benjamin Peterson7af65562008-12-29 17:56:58 +0000380- Issue #4764: With io.open, IOError.filename is set when trying to open a
381 directory on POSIX systems.
382
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000383- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

387 bytearray.translate(). It was always allowed for bytes.translate().
388
Skip Montanarof205c132008-12-23 03:30:15 +0000389- Added test case to ensure attempts to read from a file opened for writing
390 fail.
391
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000392- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

402 context manager returns a value that cannot be converted to a bool.
403
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000404- Issue #4597: Fixed several opcodes that weren't always propagating
405 exceptions.
406
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000407- Issue #4445: Replace "sizeof(PyStringObject)" with
408 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
409 str instances. On a typical machine this saves 3 bytes of memory
410 (on average) per string allocation.
411
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000412- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
413 interpreter to abort ("Fatal Python error: Could not reset the stack!")
414 instead of throwing a MemoryError.
415
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000416- Issue #3689: The list reversed iterator now supports __length_hint__
417 instead of __len__. Behavior now matches other reversed iterators.
418
Benjamin Petersonc078f922008-11-21 22:27:24 +0000419- Issue #4367: Python would segfault during compiling when the unicodedata
420 module couldn't be imported and \N escapes were present.
421
Vinay Sajip213faca2008-12-03 23:22:58 +0000422- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000423 method on file objects with closefd=False. The file descriptor is still
424 kept open but the file object behaves like a closed file. The ``FileIO``
425 object also got a new readonly attribute ``closefd``.
426
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000427- Issue #4348: Some bytearray methods returned that didn't cause any change to
428 the bytearray, returned the same bytearray instead of a copy.
429
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000430- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
431
Benjamin Peterson273c2332008-11-17 22:39:09 +0000432- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.

438
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000439- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
440 method does not return iterators for the 4th and 5th items.
441
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000442- Issue #4209: Enabling unicode_literals and the print_function in the same
443 __future__ import didn't work.
444
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000445- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000446 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000447
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000448- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
449 returned a path longer than MAX_PATH. (But It's doubtful this code path is
450 really executed because I cannot move to such directory on win2k)
451
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000452- Issue #4069: When set.remove(element) is used with a set element, the element
453 is temporarily replaced with an equivalent frozenset. But the eventual
454 KeyError would always report the empty frozenset([]) as the missing key. Now
455 it correctly refers to the initial element.
456
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000457- Issue #4509: Various issues surrounding resize of bytearray objects to
458 which there are buffer exports.
459
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000460- Issue #4748: Lambda generators no longer return a value.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000472- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
473 returned them on 64bit platforms.
474
Walter Dörwalded960ac2009-05-03 22:36:33 +0000475- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
476 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
477 step. This avoids problems with counting UTF-8 bytes that ignores the effect
478 of using the replace error handler in PyUnicode_DecodeUTF8().
479
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000480- Issue #3739: The unicode-internal encoder now reports the number of characters
481 consumed like any other encoder (instead of the number of bytes).

522
Nick Coghlan49868cb2009-11-15 07:30:34 +0000523- Issue #6816: runpy now provides a run_path function that allows Python code
524 to execute file paths that refer to source or compiled Python files as well
525 as zipfiles, directories and other valid sys.path entries that contain a

1705 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1706 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1707 skip the tests if DISPLAY is defined but can't be used.

1714 test_heapq and test_warnings have been adjusted to use it, tests for
1715 other modules with both C and Python implementations in the stdlib
1716 can be adjusted to use it over time.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001827- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1828
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001829- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1830 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1831 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1832 ``printf`` function, whereas PyString_FromFormat has an independent
1833 implementation and uses "%zd" on all platforms for size_t values.
1834 This makes a difference on win64, where ``printf`` needs "%Id" to display
1835 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001837- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1841 object; previously an int would be returned for small values. the __long__
1842 method is allowed to return either an int or a long, but the behaviour of

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001845- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001851 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001852 was correctly parsed but parsing of subsequent arguments failed.
1853
Vinay Sajip35e3b032008-09-01 14:33:59 +00001854- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001855 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1856 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1857 when given a tuple of classes as second argument, were looking up
1858 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1859 type object.
1860
Neal Norwitz18aa3882008-08-24 05:04:52 +00001861- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001998What's New in Python 2.6 beta 3?
1999================================
2000
Barry Warsaw07a4a382008-08-21 01:15:08 +00002001*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002002
2003Core and Builtins
2004-----------------
2005
Guido van Rossumf8402962008-08-20 15:01:50 +00002006- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2007 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2008 extensions do not automatically benefit from the class attribute
2009 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2010 to their tp_flags field if they care. This is a backwards
2011 compatibility feature; in 3.0, all types will use the cache by
2012 default.
2013
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002014- Keyword arguments can now follow starred arguments. (``f(a, *args,
2015 keyword=23)`` is now valid syntax.)
2016
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002017- ctypes function pointers that are COM methods have a boolean True
2018 value again.
2019
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002020- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2021 by denying s# to parse objects that have a releasebuffer procedure,
2022 and introducing s*.
2023
Georg Brandl1e13ea92008-08-11 09:07:59 +00002024- Issue #3537: Fix an assertion failure when an empty but presized dict
2025 object was stored in the freelist.
2026
Mark Dickinsonb6467572008-08-04 21:30:09 +00002027- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2028 ValueError consistently across platforms.
2029
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002030- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2031 (64bit Unix, for example), unichr() would truncate its argument and return
2032 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2033
Neal Norwitze7d8be82008-07-31 17:17:14 +00002034- Apply security patches from Apple.
2035
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002036- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2037 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2038
Antoine Pitrou92f82162008-07-25 22:22:08 +00002039- Issue #1819: function calls with several named parameters are now on
2040 average 35% faster (as measured by pybench).
2041
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002042- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2043 the python debugger steps into a class statement: the free variables (local
2044 variables defined in an outer scope) would be deleted from the outer scope.
2045
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002046- Issue #2620: Overflow checking when allocating or reallocating memory
2047 was not always being done properly in some python types and extension
2048 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2049 all been updated to perform better checks and places in the code that
2050 would previously leak memory on the error path when such an allocation
2051 failed have been fixed.
2052
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002053Library
2054-------
2055
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002056- Issue #3612: Added some missing basic types in ctypes.wintypes.
2057
Benjamin Petersone977ad42008-08-20 01:42:01 +00002058- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2059 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2060
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002061- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2062 version reported by these tools does not necessarily follow the python
2063 version numbering scheme, so the module is less strict when parsing it.
2064
Nick Coghlanf70385a2008-08-18 12:42:46 +00002065- Issue #2235: Added Py3k warnings for types which will become unhashable
2066 under the stricter __hash__ inheritance rules in 3.0. Several types
2067 which did not meet the rules for hash invariants and were already
2068 unhashable in 3.0 have now been explicitly flagged as unhashable in
2069 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2070 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2071
Brett Cannon88f801d2008-08-18 00:46:22 +00002072- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2073 imported into the module but exposed as part of the module's API.
2074
Brett Cannon7b96f072008-08-18 00:41:11 +00002075- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2076
Brett Cannon46225e72008-08-18 00:36:52 +00002077- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2078
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002079- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2080
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002081- Issue #3575: Incremental decoder's decode function now takes bytearray
2082 by using 's*' instead of 't#'.
2083
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002084- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002085 fails unicode conversion on 2nd parameter. (windows only)
2086
Facundo Batista94f243a2008-08-17 03:38:39 +00002087- Issue 2464. urllib2 now supports a malformation in the URL received
2088 in a redirect.
2089
Brett Cannonabe423e2008-08-16 21:47:07 +00002090- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002091 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002092
Facundo Batistaeb90b782008-08-16 14:44:07 +00002093- Issue #2776: fixed small issue when handling an URL with double slash
2094 after a 302 response in the case of not going through a proxy.
2095
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002096- Issue #2676: in the email package, content-type parsing was hanging on
2097 pathological input because of quadratic or exponential behaviour of a
2098 regular expression.
2099
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002100- Issue #3476: binary buffered reading through the new "io" library is now
2101 thread-safe.
2102
Brett Cannonbf3157b2008-08-14 05:00:03 +00002103- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2104 since mimetools itself is deprecated. Because modules are cached, all
2105 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2106
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002107- Issue #3134: shutil referenced undefined WindowsError symbol.
2108
Robert Schuppenies14646332008-08-10 11:01:53 +00002109- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2110 menu entries were not deleted.
2111
Brett Cannon83e81842008-08-09 23:30:55 +00002112- Copied the implementation of reduce() to _functools.reduce() to have a
2113 version that did not raise a DeprecationWarning under -3.
2114
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002115- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2116 a MemoryError rather than silently stop the iteration.
2117
Guido van Rossum59ce9012008-08-09 14:55:34 +00002118- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2119 to _sre.compile() will now be rejected. This should not affect anybody
2120 since the re.compile() function never generates invalid re-bytecode.
2121
Skip Montanaroa032bf42008-08-08 22:52:51 +00002122- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2123 upon first access it can be automatically initialized from the csv file if
2124 it wasn't initialized during instantiation.
2125
Brett Cannon3aa2a492008-08-06 22:28:09 +00002126- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2127 the reload() built-in has been removed.
2128
Brett Cannon7e30b672008-08-04 21:52:25 +00002129- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002130 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2133 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2134 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2135 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002136
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002137- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2138 raised an AttributeError.
2139
Benjamin Peterson01a24322008-07-28 23:35:27 +00002140- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002141 asking for a specific length. This problem only affected files opened
2142 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002143
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002144- Issue #3449: Update decimal module to use most recent specification
2145 (v. 1.68) and tests (v. 2.58) from IBM.
2146
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002147- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2155
2156- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2157 invalid arguments.
2158
2159- Issue #3302: Fix several crashes when calling locale's gettext functions
2160 with None arguments.
2161
2162- Issue #3389: Allow resolving dotted names for handlers in logging
2163 configuration files.
2164
2165- Deprecate the sunaudio module for removal in Python 3.0.
2166
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002167- Issue #3394: zipfile.writestr sets external attributes when passed a
2168 file name rather than a ZipInfo instance, so files are extracted with
2169 mode 0600 rather than 000 under Unix.
2170
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002171- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2172 argument in python 2.5, this broke code that subclassed Popen to include its
2173 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2181-------------
2182
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002183- Issue #2235: the C API function PyObject_HashNotImplemented and its
2184 interaction with the tp_hash slot (added in 2.6b2) are now documented
2185
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002186- Issue #643841: The language reference now provides more detailed
2187 coverage of the lookup process for special methods. The disclaimers
2188 regarding lack of coverage of new-style classes have also been
2189 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002192What's New in Python 2.6 beta 2?
2193================================
2194
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002195*Release date: 17-Jul-2008*
2196
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002197Core and Builtins
2198-----------------
2199
Georg Brandl3e483f62008-07-16 22:57:41 +00002200- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2201 its methods now allow for items objects that can be converted to
2202 an integer using operator.index().
2203
Mark Dickinson64b7e502008-07-16 09:40:03 +00002204- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2205 produced a ValueError instead of giving the correct float.
2206
Eric Smitha5fa5a22008-07-16 00:11:49 +00002207- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2208 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2209
Mark Dickinson7103aa42008-07-15 19:08:33 +00002210- Issue #3008: the float type has a new instance method 'float.hex'
2211 and a new class method 'float.fromhex' to convert floating-point
2212 numbers to and from hexadecimal strings, respectively.
2213
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002214- Issue #2235: __hash__ is once again inherited by default. To allow
2215 collections.Hashable to remain meaningful in the presence of the
2216 default hash implementation (object.__hash__), it is now possible
2217 to explicit block inheritance of hash by setting __hash__=None at
2218 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2219 level.
2220
Nick Coghlanb028f502008-07-13 14:52:36 +00002221- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2222 the parent module cannot be found while performing an absolute import.
2223 This means that an incorrectly defined __package__ attribute will
2224 now only prevent relative imports in that module rather than causing
2225 all imports from that module to fail.
2226
Nick Coghlan14ff9942008-07-08 14:21:42 +00002227- Issue #2517: Allow unicode messages in Exceptions again by correctly
2228 bypassing the instance dictionary when looking up __unicode__ on
2229 new-style classes.
2230
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002231- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2232 set to a custom object whose write() method happens to install
2233 another file in sys.stdout.
2234
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002235- Issue #3088: Corrected a race condition in classes derived from
2236 threading.local: the first member set by a thread could be saved in
2237 another thread's dictionary.
2238
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002239- Issue #3004: Minor change to slice.indices(): the start and stop
2240 arguments are now treated identically, making the behaviour easier
2241 to describe and understand. For example, slice(None, -10,
2242 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2243 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2244 10, -1).
2245
Georg Brandl278fc502008-07-19 12:46:12 +00002246- Issue #3219: Calling a function with repeated keyword arguments,
2247 f(a=2, a=23), would not cause a syntax error. This was a regression
2248 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002249
Georg Brandl278fc502008-07-19 12:46:12 +00002250- Issue #2862: Make int and float freelist management consistent with
2251 other freelists. Changes their CompactFreeList apis into
2252 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002253

2255-------
2256
Thomas Heller57adf222008-08-14 19:10:48 +00002257- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2258 api functions without holding the GIL, which could lead to a fatal
2259 error when they failed.
2260
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002261- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2270 ForkingPickler.register() to resolve conflict with ctypes.
2271
Vinay Sajip51e65192008-07-18 09:01:10 +00002272- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller2bad6572008-07-15 17:19:50 +00002277- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2278 incomplete structure was created.
2279
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002280- Issue #3339: dummy_thread.acquire() should not return None.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002698 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002699
2700 This is controlled by the configure argument ``--with-universal-archs``:
2701
2702 - ``--with-universal-archs=all``: install 4-way universal
2703
2704 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2705
2706 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2707

Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Issue #1631171: Re-implement the 'warnings' module in C (the
2761 original Python code has been kept as backup). This will allow for
2762 using the 'warning's machinery in such places as the parser where
2763 use of pure Python code is not possible. Both the ``showarning()``
2764 and ``formatwarning()`` gain an optional 'line' argument which is
2765 not called by default for backwards-compatibility reasons. Setting
2766 ``warnings.showwarning()`` to an implementation that lacks support
2767 for the ``line`` argument will raise a DeprecationWarning.

2791
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002792- The getpass module has been improved on Unix. It now uses /dev/tty
2793 by default and uses stderr instead of stdout. A GetPassWarning is
2794 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002795

Georg Brandl3ee81df2008-05-17 18:14:43 +00002809- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002810 extension modules between 32 and 64 bit platforms. See the distutls

2832 effort to facilitate running multiple instances of the entire
2833 regression test suite in parallel without issue.
2834 test_support.bind_port() has been fixed such that it will always
2835 return a unique port -- which wasn't always the case with the
2836 previous implementation, especially if socket options had been set
2837 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2838 new implementation of bind_port() will actually raise an exception
2839 if it is passed an AF_INET/SOCK_STREAM socket with either the
2840 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2841 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2842 the socket it's been passed. This currently only applies to
2843 Windows. This option prevents any other sockets from binding to the
2844 host/port we've bound to, thus removing the possibility of the
2845 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2846 when a second SOCK_STREAM socket binds and accepts to a host/port
2847 that's already been bound by another socket. The optional preferred
2848 port parameter to bind_port() has been removed. Under no
2849 circumstances should tests be hard coding ports!
2850
2851 test_support.find_unused_port() has also been introduced, which will
2852 pass a temporary socket object to bind_port() in order to obtain an
2853 unused port. The temporary socket object is then closed and
2854 deleted, and the port is returned. This method should only be used
2855 for obtaining an unused port in order to pass to an external program
2856 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2857 a parameter to a server-oriented class that doesn't give you direct
2858 access to the underlying socket used.
2859
2860 Finally, test_support.HOST has been introduced, which should be used
2861 for the host argument of any relevant socket calls (i.e. bind and
2862 connect).

2864 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002866 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2867 test_asynchat and test_socket_ssl.
2868
Georg Brandl3ee81df2008-05-17 18:14:43 +00002869 It is now possible for multiple instances of the regression test
2870 suite to run in parallel without issue.

3136Core and builtins
3137-----------------
3138
Fred Drakea8ee94b2008-03-01 02:45:07 +00003139- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003140 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003141
Georg Brandlad61bc82008-02-23 15:11:18 +00003142- Issue #2067: file.__exit__() now calls subclasses' close() method.
3143
3144- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003145
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003146- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003147 issue 215555 for a discussion.
3148
Eric Smitha73fbe72008-02-23 03:09:44 +00003149- Added the future_builtins module, which contains hex() and oct().
3150 These are the PEP 3127 version of these functions, designed to be
3151 compatible with the hex() and oct() builtins from Python 3.0. They
3152 differ slightly in their output formats from the existing, unchanged
3153 Python 2.6 builtins. The expected usage of the future_builtins
3154 module is:
3155 from future_builtins import hex, oct
3156
Eric Smith7ef40bf2008-02-20 23:34:22 +00003157- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3158 exponents for exponents with absolute value < 100. Follows C99
3159 standard. This is a change on Windows, which would use 3 digits.
3160 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3161 so that any alterations it does to the resulting string will be
3162 available in stringlib/formatter.h (for float.__format__).
3163
Eric Smith5a3c1352008-02-19 13:21:56 +00003164- Implemented PEP 3101, Advanced String Formatting. This adds a new
3165 builtin format(); a format() method for str and unicode; a
3166 __format__() method to object, str, unicode, int, long, float, and
3167 datetime; the class string.Formatter; and the C API
3168 PyObject_Format().
3169
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170- Fixed several potential crashes, all caused by specially crafted
3171 __del__ methods exploiting objects in temporarily inconsistent
3172 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003173
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003174- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003175 prevent a possible crash: an Abstract Base Class would try to access
3176 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003177
Georg Brandl3ee81df2008-05-17 18:14:43 +00003178- Fixed repr() and str() of complex numbers with infinity or nan as
3179 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003180
Georg Brandl3ee81df2008-05-17 18:14:43 +00003181- Clear all free lists during a gc.collect() of the highest generation
3182 in order to allow pymalloc to free more arenas. Python may give back
3183 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Issue #2045: Fix an infinite recursion triggered when printing a
3186 subclass of collections.defaultdict, if its default_factory is set
3187 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003188
Christian Heimesf75dbef2008-02-08 00:11:31 +00003189- Fixed a minor memory leak in dictobject.c. The content of the free
3190 list was not freed on interpreter shutdown.
3191
Georg Brandl3ee81df2008-05-17 18:14:43 +00003192- Limit free list of method and builtin function objects to 256
3193 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003194
Georg Brandl3ee81df2008-05-17 18:14:43 +00003195- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3196 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003197 to compact the internal free lists of pre-allocted ints and floats.
3198
Georg Brandl3ee81df2008-05-17 18:14:43 +00003199- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3200 calls. Python expected the return type int but the fork familie
3201 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003202
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3204 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003205
Georg Brandl3ee81df2008-05-17 18:14:43 +00003206- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3207 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003208
Georg Brandl3ee81df2008-05-17 18:14:43 +00003209- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3210 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003211
Georg Brandl3ee81df2008-05-17 18:14:43 +00003212- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3213 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003214
Georg Brandl3ee81df2008-05-17 18:14:43 +00003215- Patch #1473257: generator objects gain a gi_code attribute. This is
3216 the same object as the func_code attribute of the function that
3217 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003218
Georg Brandl3ee81df2008-05-17 18:14:43 +00003219- Issue #1920: "while 0" statements were completely removed by the
3220 compiler, even in the presence of an "else" clause, which is
3221 supposed to be run when the condition is false. Now the compiler
3222 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003223
Guido van Rossumeead05f2008-01-24 18:21:02 +00003224- A few crashers fixed: weakref_in_del.py (issue #1377858);
3225 loosing_dict_ref.py (issue #1303614, test67.py);
3226 borrowed_ref_[34].py (not in tracker).
3227
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003228- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003229 suppressed while an extension is loaded by calling SetErrorMode in
3230 dynload_win.c. The error is still reported properly.
3231
Georg Brandl3ee81df2008-05-17 18:14:43 +00003232- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003233 several extension methods and modules do not work without unicode
3234 support.
3235
Georg Brandl26543b12008-01-21 18:36:51 +00003236- Issue #1882: when compiling code from a string, encoding cookies in the
3237 second line of code were not always recognized correctly.
3238
Georg Brandl14404b62008-01-19 19:27:05 +00003239- Issue #1679: "0x" was taken as a valid integer literal.
3240
Georg Brandl6caad7d2008-01-26 14:19:22 +00003241- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003242 added.
3243
Christian Heimesc94e2b52008-01-14 04:13:37 +00003244- sys.float_info / PyFloat_GetInfo: The floating point information
3245 object was converted from a dict to a specialized structseq object.
3246
Georg Brandl3ee81df2008-05-17 18:14:43 +00003247- Patch #1816: Added sys.flags structseq. It exposes the status of
3248 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Objects/structseq.c: Implemented new structseq representation. The
3251 patch makes structseqs (e.g. the return value of os.stat) more
3252 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- Patch #1700288: added a type attribute cache that caches method
3255 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003256
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003257- Bug #1776: __import__() no longer accepts filenames on any platform.
3258 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003259
Georg Brandlaed6c662008-01-07 17:25:53 +00003260- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3261
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3263 envvar and sys.dont_write_bytecode attribute. All these can be set
3264 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003265
Georg Brandl3ee81df2008-05-17 18:14:43 +00003266- Improve some exception messages when Windows fails to load an
3267 extension module. Now we get for example '%1 is not a valid Win32
3268 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003269
Georg Brandl3ee81df2008-05-17 18:14:43 +00003270- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003272- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3273 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003274
Christian Heimes0a8143f2007-12-18 23:22:54 +00003275- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003276 and INF. float("nan"), float("inf") and float("-inf") now work on
3277 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003278
Georg Brandl3ee81df2008-05-17 18:14:43 +00003279- Compiler now generates simpler and faster code for dictionary
3280 literals. The oparg for BUILD_MAP now indicates an estimated
3281 dictionary size. There is a new opcode, STORE_MAP, for adding
3282 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003283
Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003292- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003293 SystemError.
3294
Nick Coghlanef01d822007-12-03 12:55:17 +00003295- PEP 366: Allow explicit relative imports when executing modules
3296 inside packages with the -m switch via a new module level
3297 __package__ attribute.
3298
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299- Issue #1402: Fix a crash on exit, when another thread is still
3300 running, and if the deallocation of its frames somehow calls the
3301 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003302

3312 file can now be directly executed by passing their name to the
3313 interpreter. The directory/zipfile is automatically inserted as the
3314 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003315
Georg Brandl3ee81df2008-05-17 18:14:43 +00003316- Issue #1265: Fix a problem with sys.settrace, if the tracing
3317 function uses a generator expression when at the same time the
3318 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003319
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003320- sets and frozensets now have an isdisjoint() method.
3321
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003322- optimize the performance of builtin.sum().
3323
Neal Norwitz44f326e2007-10-05 05:29:17 +00003324- Fix warnings found by the new version of the Coverity checker.
3325
Georg Brandl3ee81df2008-05-17 18:14:43 +00003326- The enumerate() builtin function is no longer bounded to sequences
3327 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3328 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003329
Georg Brandl3ee81df2008-05-17 18:14:43 +00003330- Issue #1686386: Tuple's tp_repr did not take into account the
3331 possibility of having a self-referential tuple, which is possible
3332 from C code. Nor did object's tp_str consider that a type's tp_str
3333 could do something that could lead to an inifinite recursion.
3334 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3335 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003336
Georg Brandl3ee81df2008-05-17 18:14:43 +00003337- Issue #1164: It was possible to trigger deadlock when using the
3338 'print' statement to write to a file since the GIL was not released
3339 as needed. Now PyObject_Print() does the right thing along with
3340 various tp_print implementations of the built-in types and those in

Georg Brandl3ee81df2008-05-17 18:14:43 +00003343- Issue #1147: Exceptions were directly allowing string exceptions in
3344 their throw() method even though string exceptions no longer
3345 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003346
Georg Brandl3ee81df2008-05-17 18:14:43 +00003347- Issue #1096: Prevent a segfault from getting the repr of a very
3348 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00003350- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003351 PyObject_Call() never calling back out to Python code to trigger
3352 recursion depth updates/checks. Required the creation of a static
3353 RuntimeError instance in case normalizing an exception put the
3354 recursion check value past its limit. Fixes crashers
3355 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003370- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003371 __*__ attributes. (Some already existed, e.g., __doc__ and
3372 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003373
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003374- Add -3 option to the interpreter to warn about features that are

3378 calls.
3379
Collin Winter62903052007-05-18 23:11:24 +00003380- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003381 "except E as target:". This is to provide forwards compatibility
3382 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003383
Brett Cannon229cee22007-05-05 01:34:02 +00003384- Deprecate BaseException.message as per PEP 352.
3385
Georg Brandl3ee81df2008-05-17 18:14:43 +00003386- Issue #1303614: don't expose object's __dict__ when the dict is

3388
Vinay Sajip8549ce32007-05-06 17:53:37 +00003389- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003390 setting a plain string, ie don't expand to single letter identifiers.
3391
Raymond Hettinger13936692007-04-11 18:40:58 +00003392- Request #1191699: Slices can now be pickled.
3393
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003394- Request #1193128: str.translate() now allows a None argument for
3395 translations that only remove characters without re-mapping the
3396 remaining characters.
3397
Georg Brandl5cb76c12007-03-21 09:00:39 +00003398- Patch #1682205: a TypeError while unpacking an iterable is no longer

3400
Neal Norwitzaa754b72007-03-21 06:39:48 +00003401- Remove unused file Python/fmod.c.
3402
Guido van Rossum143b5642007-03-23 04:58:42 +00003403- Bug #1683368: The object.__init__() and object.__new__() methods are
3404 now stricter in rejecting excess arguments. The only time when
3405 either allows excess arguments is when it is not overridden and the
3406 other one is. For backwards compatibility, when both are
3407 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003408 warning later). Also, type.__init__() insists on the same signature
3409 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003410
Georg Brandl3ee81df2008-05-17 18:14:43 +00003411- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3412 object to complex using its __complex__() method before falling back
3413 to the __float__() method. Therefore, the functions in the cmath
3414 module now can operate on objects that define a __complex__()
3415 method.

3418 __slots__. The old and the new class are still required to have the
3419 same slot names.

3432
Georg Brandl7b9c5552007-03-12 14:30:05 +00003433- Bug #1678647: write a newline after printing an exception in any
3434 case, even when converting the value to a string failed.
3435
Georg Brandl871f1bc2007-03-12 13:17:36 +00003436- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003437 its argument, if it exists. If not, it will work like before. This
3438 allows customizing the output of dir() in the presence of a
3439 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003440
Collin Winter276887b2007-03-12 16:11:39 +00003441- Patch #922167: Python no longer segfaults when faced with infinitely
3442 self-recursive reload() calls (as reported by bug #742342).
3443

3448 parthensized forms. This means complex(repr(x)) now works instead of
3449 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003450
Georg Brandlaa2321b2007-03-07 00:40:28 +00003451- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003452 makes the filenames the warning module prints much more sensible
3453 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003454

Georg Brandl0fca97a2007-03-05 22:28:08 +00003466- Patch #1674228: when assigning a slice (old-style), check for the
3467 sq_ass_slice instead of the sq_slice slot.
3468
Georg Brandl3ee81df2008-05-17 18:14:43 +00003469- When printing an unraisable error, don't print exceptions. before
3470 the name. This duplicates the behavior whening normally printing
3471 exceptions.

4080 Python would crash instead of raising an error.
4081
Thomas Hellerc2f77252007-03-09 19:21:28 +00004082- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
4083 returned string up to the first NUL character.

4094
Georg Brandl3ee81df2008-05-17 18:14:43 +00004095- unittest now verifies more of its assumptions. In particular,
4096 TestCase and TestSuite subclasses (not instances) are no longer
4097 accepted in TestSuite.addTest(). This should cause no
4098 incompatibility since it never made sense with ordinary subclasses
4099 -- the failure just occurred later, with a more cumbersome
4100 exception.

4383 obtained from the TLS negotiation itself. Patch contributed by Bill
4384 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004385
Georg Brandl3ee81df2008-05-17 18:14:43 +00004386- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004387 that the SMTP.starttls() caller no longer needs to call ehlo()
4388 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004389 does not claim to support starttls. Adds the
4390 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4471 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4472 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004489 time so that opening a database previously created with the DB_DUP
4490 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4491 opens. Specifically: dictionary assignment to a DB object will
4492 replace all values for a given key when the database allows
4493 duplicate values. DB users should use DB.put(k, v) when they want
4494 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004495

4501 characters with ASCII value less than 32. Also, it correctly quotes
4502 dots only if they occur on a single line, as opposed to the previous
4503 behavior of quoting dots if they are the second character of any
4504 line.

4827-----
4828
Georg Brandl3ee81df2008-05-17 18:14:43 +00004829- Unified naming convention for free lists and their limits. All free
4830 lists in Object/ are named ``free_list``, the counter ``numfree``
4831 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4832 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004833
Georg Brandl3ee81df2008-05-17 18:14:43 +00004834- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4835 to ``PyTuple_SetItem``, it can be used to populate a brand new
4836 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004837
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004838- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004840- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4841 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4842 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004843
4844- Patch #1720595: add T_BOOL to the range of structmember types.
4845
4846- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4847 ``PyFloat_GetInfo()`` to the float API.
4848
Georg Brandl3ee81df2008-05-17 18:14:43 +00004849- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4850 of w# format code incorrectly truncated the length to an int, even
4851 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4852 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004853
Georg Brandl3ee81df2008-05-17 18:14:43 +00004854- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4855 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004857- PEP 3123: Provide forward compatibility with Python 3.0, while
4858 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4859 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004860
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4862 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004863
4864- Patch #1733960: Allow T_LONGLONG to accept ints.

4871
4872- Fix some leftovers from the conversion from int to Py_ssize_t
4873 (relevant to strings and sequences of more than 2**31 items).
4874
4875- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4876 outside of pystate.c and should not be necessary.
4877
Georg Brandl3ee81df2008-05-17 18:14:43 +00004878- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4879 absolute imports. In earlier versions they might have used relative
4880 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004881
Georg Brandl3ee81df2008-05-17 18:14:43 +00004882- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4883 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004884
Georg Brandl3ee81df2008-05-17 18:14:43 +00004885- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4886 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004892- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4893 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4894 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4895 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004896
Georg Brandl3ee81df2008-05-17 18:14:43 +00004897- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004910- Removed the macfs module. It had been deprecated since Python 2.5.
4911 This lead to the deprecation of macostools.touched() as it relied
4912 solely on macfs and was a no-op under OS X.
