36Core and Builtins
37-----------------
38
Benjamin Petersonecdae192010-01-04 00:43:01 +000039- The __complex__ method is now looked up on the class of instances to make it
40 consistent with other special methods.
41
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000042- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
43 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
44
Mark Dickinson1b34d252010-01-01 17:27:30 +000045- Issue #5080: A number of functions and methods previously produced a
46 DeprecationWarning when passed a float argument where an integer was
47 expected. These functions and methods now raise TypeError instead.
48 The majority of the effects of this change are in the extension
49 modules, but some core functions and methods are affected: notably
50 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
51 methods.
52
Benjamin Peterson0f02d392009-12-30 19:34:10 +000053- Issue #7604: Deleting an unset slotted attribute did not raise an
54 AttributeError.
55
Mark Dickinson99d652e2009-12-30 12:12:23 +000056- Issue #7534: Fix handling of IEEE specials (infinities, nans,
57 negative zero) in ** operator. The behaviour now conforms to that
58 described in C99 Annex F.
59
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000060- Issue #7579: the msvcrt module now has docstrings for all its functions.
61
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000062- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
63 used to drop the time part of the result.
64
Mark Dickinson46572832009-12-27 14:55:57 +000065- Issue #1811: improve accuracy and cross-platform consistency for
66 true division of integers: the result of a/b is now correctly
67 rounded for ints a and b (at least on IEEE 754 platforms), and in
68 particular does not depend on the internal representation of a long.
69
Ezio Melottif84caf42009-12-24 22:25:17 +000070- Issue #6108: unicode(exception) and str(exception) should return the same
71 message when only __str__ (and not __unicode__) is overridden in the subclass.
72
Ronald Oussoren92919a62009-12-24 13:30:58 +000073- Issue #6834: replace the implementation for the 'python' and 'pythonw'
74 executables on OSX.
75
76 These executables now work properly with the arch(1) command:
77 ``arch -ppc python`` will start a universal binary version of python
78 in PPC mode (unlike previous releases).
79
R. David Murray0a0a1a82009-12-14 16:28:26 +000080- Issue #1680159: unicode coercion during an 'in' operation no longer masks
81 the underlying error when the coercion fails for the left hand operand.
82
Benjamin Peterson4895af42009-12-13 16:36:53 +000083- Issue #7491: Metaclass's __cmp__ method was ignored.

93 gcc when it has a fully qualified configuration prefix. Initial patch
94 by Arfrever.
95
Antoine Pitrou80157252010-01-08 19:20:17 +000096- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
97 renaming of `cPickle` to `pickle`. The warning was annoying since there's
98 no alternative to cPickle if you care about performance. Patch by Florent
99 Xicluna.

108 and make it implement the `io.BufferedIOBase` ABC to allow for further
109 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
110
111- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000112 parameter to allow specifying where your connections come from.

Senthil Kumaran7713acf2009-12-20 06:05:13 +0000130 Patch by Tatsuhiro Tsujikawa.
131
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000132- Issue #7349: Make methods of file objects in the io module accept None as an
133 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
134 the same as passing no argument.
135
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000136- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
137 like other file objects.
138
Lars Gustäbel92ca7562009-12-13 11:32:27 +0000139- Issue #7357: tarfile no longer suppresses fatal extraction errors by
140 default.

R. David Murray93321f32009-12-09 15:15:31 +0000144- Issue #5949: fixed IMAP4_SSL hang when the IMAP server response is
145 missing proper end-of-line termination.
146
Tarek Ziadé2421d562009-12-20 23:23:34 +0000147- Issue #7457: added a read_pkg_file method to

157 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
158 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
159 arguments for integer format codes (other than 'L'): previously an

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000207- Issue #7419: setlocale() could crash the interpreter on Windows when called
208 with invalid values.
209
Eric Smithc4ab8332009-11-29 17:40:57 +0000210- Issue #3382: 'F' formatting for float and complex now convert the
211 result to upper case. This only affects 'inf' and 'nan', since 'f'
212 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000213
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000214- Remove switch from "%f" formatting to "%g" formatting for floats
215 larger than 1e50 in absolute value.
216
Mark Dickinson18cfada2009-11-23 18:46:41 +0000217- Remove restrictions on precision when formatting floats. E.g.,
218 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
219 requested 120 significant digits instead.
220
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000221- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000225- Issue #7085: Fix crash when importing some extensions in a thread
226 on MacOSX 10.6.
227
Mark Dickinsonb678de82009-11-19 18:41:49 +0000228- Issue #7117: repr(x) for a float x returns a result based on the
229 shortest decimal string that's guaranteed to round back to x under
230 correct rounding (with round-half-to-even rounding mode).
231 Previously it gave a string based on rounding x to 17 decimal digits.
232 repr(x) for a complex number behaves similarly. On platforms where
233 the correctly-rounded strtod and dtoa code is not supported (see below),
234 repr is unchanged.
235
236- Issue #7117: On almost all platforms: float-to-string and
237 string-to-float conversions within Python are now correctly rounded.
238 Places these conversions occur include: str for floats and complex
239 numbers; the float and complex constructors; old-style and new-style
240 numeric formatting; serialization and deserialization of floats and
241 complex numbers using marshal, pickle and json; parsing of float and
242 imaginary literals in Python code; Decimal-to-float conversion.
243
244 The conversions use a Python-adapted version of David Gay's
245 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
246 functions. This code is supported on Windows, and on Unix-like
247 platforms using gcc, icc or suncc as the C compiler. There may be a
248 small number of platforms on which correct operation of this code
249 cannot be guaranteed, so the code is not used: notably, this applies
250 to platforms where the C double format is not IEEE 754 binary64, and
251 to platforms on x86 hardware where the x87 FPU is set to 64-bit
252 precision and Python's configure script is unable to determine how
253 to change the FPU precision. On these platforms conversions use the
254 platform strtod and dtoa, as before.
255
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000256- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000257 now uses the correctly-rounded string <-> float conversions
258 described above (when available), and so produces correctly rounded
259 results that will display nicely under the float repr. There are
260 two related small changes: (1) round now accepts any class with an
261 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000262 floats for the second argument), and (2) an excessively large second
263 integer argument (e.g., round(1.234, 10**100)) no longer raises an
264 exception.
265
Philip Jenveyfab8be22009-11-17 02:42:26 +0000266- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.

Benjamin Petersone36199b2009-11-12 23:39:44 +0000268- Fix several issues with compile(). The input can now contain Windows and Mac
269 newlines and is no longer required to end in a newline.
270

409 was locale aware; and (3) the interpretation of fromhex('-nan')
410 didn't match that of float('-nan').
411
Eric Smitha985a3a2009-05-05 18:26:08 +0000412- Issue #5920: For float.__format__, change the behavior with the
413 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
414 to be like 'g' but with at least one decimal point and with a
415 default precision of 12. Previously, the behavior the same but with
416 a default precision of 6. This more closely matches str(), and
417 reduces surprises when adding alignment flags to the empty
418 presentation type. This also affects the new complex.__format__ in
419 the same way.
420
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000421- Issue #5890: in subclasses of 'property' the __doc__ attribute was

484 untrackable objects are not tracked by the garbage collector. This can
485 reduce the size of collections and therefore the garbage collection overhead
486 on long-running programs, depending on their particular use of datatypes.
487
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000488- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

493 2**15 for the internal representation of integers, for performance
494 reasons. Base 2**30 is enabled by default on 64-bit machines. Add

496 default. Add sys.long_info structseq to provide information about
497 the internal format.

521 on a 64-bit system.
522
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000523- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

530
Georg Brandl29c6a282009-04-05 20:23:13 +0000531- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000532 were suppressing all exceptions. These include list(), filter(), map(),

604 exceptions.
605
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000606- Issue #4445: Replace "sizeof(PyStringObject)" with
607 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
608 str instances. On a typical machine this saves 3 bytes of memory
609 (on average) per string allocation.
610
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000611- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
612 interpreter to abort ("Fatal Python error: Could not reset the stack!")
613 instead of throwing a MemoryError.
614
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000615- Issue #3689: The list reversed iterator now supports __length_hint__

617
Benjamin Petersonc078f922008-11-21 22:27:24 +0000618- Issue #4367: Python would segfault during compiling when the unicodedata

620
Vinay Sajip213faca2008-12-03 23:22:58 +0000621- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000622 method on file objects with closefd=False. The file descriptor is still
623 kept open but the file object behaves like a closed file. The ``FileIO``
624 object also got a new readonly attribute ``closefd``.
625
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000626- Issue #4348: Some bytearray methods returned that didn't cause any change to

643
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000644- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000645 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000647- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
648 returned a path longer than MAX_PATH. (But It's doubtful this code path is
649 really executed because I cannot move to such directory on win2k)
650
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000651- Issue #4069: When set.remove(element) is used with a set element, the element
652 is temporarily replaced with an equivalent frozenset. But the eventual
653 KeyError would always report the empty frozenset([]) as the missing key. Now
654 it correctly refers to the initial element.

672 returned them on 64bit platforms.
673
Walter Dörwalded960ac2009-05-03 22:36:33 +0000674- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
675 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
676 step. This avoids problems with counting UTF-8 bytes that ignores the effect
677 of using the replace error handler in PyUnicode_DecodeUTF8().
678
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000679- Issue #3739: The unicode-internal encoder now reports the number of characters
680 consumed like any other encoder (instead of the number of bytes).
681
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000682- Issue #2422: When compiled with the ``--with-valgrind`` option, the
683 pymalloc allocator will be automatically disabled when running under
684 Valgrind. This gives improved memory leak detection when running
685 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +0000754- Issue #6816: runpy now provides a run_path function that allows Python code
755 to execute file paths that refer to source or compiled Python files as well
756 as zipfiles, directories and other valid sys.path entries that contain a

1858 integer now consistently raises struct.error.
1859
Mark Dickinson463dc4b2009-07-05 10:01:24 +00001860- Issues #1530559, #1741130: Fix various struct.pack inconsistencies
1861 for the integer formats ('bBhHiIlLqQ'). In the following, '*'

1866
1867 - If x is not an int, long or float, then packing x will always
1868 result in struct.error. Previously an x with an __int__ method

R. David Murray820b0ea2009-12-03 23:57:59 +00001907 file in the Lib/test directory, which might be read-only for the

R. David Murrayda826892009-11-15 00:04:32 +00001910- Issue #7324: add a sanity check to regrtest argument parsing to

Antoine Pitrou59c44f32009-10-30 17:07:08 +00001921- Issue #7222: Make thread "reaping" more reliable so that reference
1922 leak-chasing test runs give sensible results. The previous method of
1923 reaping threads could return successfully while some Thread objects were
1924 still referenced. This also introduces a new private function:
1925 :func:`thread._count()`.
1926
R. David Murray282396f2009-10-18 21:12:37 +00001927- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1929
Antoine Pitrou58d2f262009-10-10 20:52:11 +00001930- Issue #7055: test___all__ now greedily detects all modules which have an

1932
R. David Murray14dcd432009-10-14 13:58:07 +00001933- Issue #7058: Added save/restore for things like sys.argv and cwd to

1943 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1944 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1945 skip the tests if DISPLAY is defined but can't be used.
1946
Antoine Pitrou4698d992009-05-31 14:20:14 +00001947- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

1951 it easy to import both normal and optimised versions of modules.
1952 test_heapq and test_warnings have been adjusted to use it, tests for
1953 other modules with both C and Python implementations in the stdlib
1954 can be adjusted to use it over time.

Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001963 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001964 from test support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002065- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2066
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002067- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2068 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2069 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2070 ``printf`` function, whereas PyString_FromFormat has an independent
2071 implementation and uses "%zd" on all platforms for size_t values.
2072 This makes a difference on win64, where ``printf`` needs "%Id" to display
2073 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002075- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2079 object; previously an int would be returned for small values. the __long__
2080 method is allowed to return either an int or a long, but the behaviour of
2081 float objects should not change to respect backward compatibility.
2082
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002083- Issue #3751: str.rpartition would perform a left-partition when called with
2084 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002089 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002090 was correctly parsed but parsing of subsequent arguments failed.
2091
Vinay Sajip35e3b032008-09-01 14:33:59 +00002092- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002093 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2094 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2095 when given a tuple of classes as second argument, were looking up
2096 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2097 type object.
2098
Neal Norwitz18aa3882008-08-24 05:04:52 +00002099- Fix crashes on memory allocation failure found with failmalloc.

2242-----------------
2243
Guido van Rossumf8402962008-08-20 15:01:50 +00002244- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2245 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2246 extensions do not automatically benefit from the class attribute
2247 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2248 to their tp_flags field if they care. This is a backwards
2249 compatibility feature; in 3.0, all types will use the cache by
2250 default.
2251
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002252- Keyword arguments can now follow starred arguments. (``f(a, *args,
2253 keyword=23)`` is now valid syntax.)
2254
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002255- ctypes function pointers that are COM methods have a boolean True
2256 value again.
2257
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002258- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2259 by denying s# to parse objects that have a releasebuffer procedure,
2260 and introducing s*.
2261
Georg Brandl1e13ea92008-08-11 09:07:59 +00002262- Issue #3537: Fix an assertion failure when an empty but presized dict
2263 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00002265- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2266 ValueError consistently across platforms.
2267
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002268- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2269 (64bit Unix, for example), unichr() would truncate its argument and return
2270 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002274- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2275 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2276
Antoine Pitrou92f82162008-07-25 22:22:08 +00002277- Issue #1819: function calls with several named parameters are now on
2278 average 35% faster (as measured by pybench).
2279
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002280- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2281 the python debugger steps into a class statement: the free variables (local
2282 variables defined in an outer scope) would be deleted from the outer scope.
2283
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002284- Issue #2620: Overflow checking when allocating or reallocating memory
2285 was not always being done properly in some python types and extension
2286 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2287 all been updated to perform better checks and places in the code that
2288 would previously leak memory on the error path when such an allocation
2289 failed have been fixed.

2295
Benjamin Petersone977ad42008-08-20 01:42:01 +00002296- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2297 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2298
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002299- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2300 version reported by these tools does not necessarily follow the python
2301 version numbering scheme, so the module is less strict when parsing it.
2302
Nick Coghlanf70385a2008-08-18 12:42:46 +00002303- Issue #2235: Added Py3k warnings for types which will become unhashable
2304 under the stricter __hash__ inheritance rules in 3.0. Several types
2305 which did not meet the rules for hash invariants and were already
2306 unhashable in 3.0 have now been explicitly flagged as unhashable in
2307 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2308 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2309
Brett Cannon88f801d2008-08-18 00:46:22 +00002310- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2311 imported into the module but exposed as part of the module's API.
2312

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002319- Issue #3575: Incremental decoder's decode function now takes bytearray
2320 by using 's*' instead of 't#'.
2321
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002322- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002323 fails unicode conversion on 2nd parameter. (windows only)

2332 after a 302 response in the case of not going through a proxy.
2333
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002334- Issue #2676: in the email package, content-type parsing was hanging on
2335 pathological input because of quadratic or exponential behaviour of a
2336 regular expression.
2337
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002338- Issue #3476: binary buffered reading through the new "io" library is now
2339 thread-safe.
2340
Brett Cannonbf3157b2008-08-14 05:00:03 +00002341- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2342 since mimetools itself is deprecated. Because modules are cached, all
2343 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2344
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002345- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002347- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2348 menu entries were not deleted.
2349
Brett Cannon83e81842008-08-09 23:30:55 +00002350- Copied the implementation of reduce() to _functools.reduce() to have a
2351 version that did not raise a DeprecationWarning under -3.
2352
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002353- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2354 a MemoryError rather than silently stop the iteration.
2355
Guido van Rossum59ce9012008-08-09 14:55:34 +00002356- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2357 to _sre.compile() will now be rejected. This should not affect anybody
2358 since the re.compile() function never generates invalid re-bytecode.
2359
Skip Montanaroa032bf42008-08-08 22:52:51 +00002360- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2361 upon first access it can be automatically initialized from the csv file if
2362 it wasn't initialized during instantiation.
2363
Brett Cannon3aa2a492008-08-06 22:28:09 +00002364- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2365 the reload() built-in has been removed.
2366
Brett Cannon7e30b672008-08-04 21:52:25 +00002367- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002368 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2376 raised an AttributeError.
2377
Benjamin Peterson01a24322008-07-28 23:35:27 +00002378- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002379 asking for a specific length. This problem only affected files opened
2380 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002381
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002382- Issue #3449: Update decimal module to use most recent specification
2383 (v. 1.68) and tests (v. 2.58) from IBM.
2384

2404
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002405- Issue #3394: zipfile.writestr sets external attributes when passed a
2406 file name rather than a ZipInfo instance, so files are extracted with
2407 mode 0600 rather than 000 under Unix.
2408
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002409- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2410 argument in python 2.5, this broke code that subclassed Popen to include its
2411 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2420
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002421- Issue #2235: the C API function PyObject_HashNotImplemented and its
2422 interaction with the tp_hash slot (added in 2.6b2) are now documented
2423
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002424- Issue #643841: The language reference now provides more detailed
2425 coverage of the lookup process for special methods. The disclaimers
2426 regarding lack of coverage of new-style classes have also been
2427 removed, since the coverage is now fairly reasonable.

2431================================
2432
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002433*Release date: 17-Jul-2008*
2434
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002435Core and Builtins
2436-----------------
2437
Georg Brandl3e483f62008-07-16 22:57:41 +00002438- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2439 its methods now allow for items objects that can be converted to
2440 an integer using operator.index().
2441
Mark Dickinson64b7e502008-07-16 09:40:03 +00002442- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2443 produced a ValueError instead of giving the correct float.
2444
Eric Smitha5fa5a22008-07-16 00:11:49 +00002445- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2446 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2447
Mark Dickinson7103aa42008-07-15 19:08:33 +00002448- Issue #3008: the float type has a new instance method 'float.hex'
2449 and a new class method 'float.fromhex' to convert floating-point
2450 numbers to and from hexadecimal strings, respectively.
2451
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002452- Issue #2235: __hash__ is once again inherited by default. To allow
2453 collections.Hashable to remain meaningful in the presence of the
2454 default hash implementation (object.__hash__), it is now possible
2455 to explicit block inheritance of hash by setting __hash__=None at
2456 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2457 level.
2458
Nick Coghlanb028f502008-07-13 14:52:36 +00002459- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2460 the parent module cannot be found while performing an absolute import.
2461 This means that an incorrectly defined __package__ attribute will
2462 now only prevent relative imports in that module rather than causing
2463 all imports from that module to fail.
2464
Nick Coghlan14ff9942008-07-08 14:21:42 +00002465- Issue #2517: Allow unicode messages in Exceptions again by correctly
2466 bypassing the instance dictionary when looking up __unicode__ on
2467 new-style classes.
2468
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002469- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2470 set to a custom object whose write() method happens to install
2471 another file in sys.stdout.
2472
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002473- Issue #3088: Corrected a race condition in classes derived from
2474 threading.local: the first member set by a thread could be saved in
2475 another thread's dictionary.
2476
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002477- Issue #3004: Minor change to slice.indices(): the start and stop
2478 arguments are now treated identically, making the behaviour easier
2479 to describe and understand. For example, slice(None, -10,
2480 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2481 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2482 10, -1).
2483
Georg Brandl278fc502008-07-19 12:46:12 +00002484- Issue #3219: Calling a function with repeated keyword arguments,
2485 f(a=2, a=23), would not cause a syntax error. This was a regression
2486 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002487
Georg Brandl278fc502008-07-19 12:46:12 +00002488- Issue #2862: Make int and float freelist management consistent with
2489 other freelists. Changes their CompactFreeList apis into
2490 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002491

2493-------
2494
Thomas Heller57adf222008-08-14 19:10:48 +00002495- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2496 api functions without holding the GIL, which could lead to a fatal
2497 error when they failed.
2498
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002499- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002507- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2508 ForkingPickler.register() to resolve conflict with ctypes.
2509
Vinay Sajip51e65192008-07-18 09:01:10 +00002510- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002511
Thomas Heller880f5292008-07-15 19:39:38 +00002512- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2513 a valid dlerror() message.
2514
Thomas Heller2bad6572008-07-15 17:19:50 +00002515- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2516 incomplete structure was created.
2517
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002518- Issue #3339: dummy_thread.acquire() should not return None.

2521
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002522- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002523
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002524- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2525 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002526 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002527 content-length. The problem had been corrected in the 2.4 branch, but never
2528 merged into trunk.
2529
Georg Brandle78fbcc2008-07-05 10:13:36 +00002530- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002541 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002542
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002543- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2544 handling is now the same as that of other special attributes like __name__).
2545
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002546- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2547 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002936 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002937
2938 This is controlled by the configure argument ``--with-universal-archs``:
2939
2940 - ``--with-universal-archs=all``: install 4-way universal
2941
2942 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2943
2944 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2945
2946 This option should be used in combination with ``--enable-universalsdk=``.
2947
2948 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 +00002998- Issue #1631171: Re-implement the 'warnings' module in C (the
2999 original Python code has been kept as backup). This will allow for
3000 using the 'warning's machinery in such places as the parser where
3001 use of pure Python code is not possible. Both the ``showarning()``
3002 and ``formatwarning()`` gain an optional 'line' argument which is
3003 not called by default for backwards-compatibility reasons. Setting
3004 ``warnings.showwarning()`` to an implementation that lacks support
3005 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003068- Issue #2550: The approach used by client/server code for obtaining
3069 ports to listen on in network-oriented tests has been refined in an
3070 effort to facilitate running multiple instances of the entire
3071 regression test suite in parallel without issue.
3072 test_support.bind_port() has been fixed such that it will always
3073 return a unique port -- which wasn't always the case with the
3074 previous implementation, especially if socket options had been set
3075 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3076 new implementation of bind_port() will actually raise an exception
3077 if it is passed an AF_INET/SOCK_STREAM socket with either the
3078 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3079 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3080 the socket it's been passed. This currently only applies to
3081 Windows. This option prevents any other sockets from binding to the
3082 host/port we've bound to, thus removing the possibility of the
3083 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3084 when a second SOCK_STREAM socket binds and accepts to a host/port
3085 that's already been bound by another socket. The optional preferred
3086 port parameter to bind_port() has been removed. Under no
3087 circumstances should tests be hard coding ports!
3088
3089 test_support.find_unused_port() has also been introduced, which will
3090 pass a temporary socket object to bind_port() in order to obtain an
3091 unused port. The temporary socket object is then closed and
3092 deleted, and the port is returned. This method should only be used
3093 for obtaining an unused port in order to pass to an external program
3094 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3095 a parameter to a server-oriented class that doesn't give you direct
3096 access to the underlying socket used.
3097
3098 Finally, test_support.HOST has been introduced, which should be used
3099 for the host argument of any relevant socket calls (i.e. bind and
3100 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003101
3102 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003103 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3106
Georg Brandl3ee81df2008-05-17 18:14:43 +00003107 It is now possible for multiple instances of the regression test
3108 suite to run in parallel without issue.

3374Core and builtins
3375-----------------
3376
Fred Drakea8ee94b2008-03-01 02:45:07 +00003377- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003378 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003379
Georg Brandlad61bc82008-02-23 15:11:18 +00003380- Issue #2067: file.__exit__() now calls subclasses' close() method.
3381
3382- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003383
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003384- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003385 issue 215555 for a discussion.
3386
Eric Smitha73fbe72008-02-23 03:09:44 +00003387- Added the future_builtins module, which contains hex() and oct().
3388 These are the PEP 3127 version of these functions, designed to be
3389 compatible with the hex() and oct() builtins from Python 3.0. They
3390 differ slightly in their output formats from the existing, unchanged
3391 Python 2.6 builtins. The expected usage of the future_builtins
3392 module is:
3393 from future_builtins import hex, oct
3394
Eric Smith7ef40bf2008-02-20 23:34:22 +00003395- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3396 exponents for exponents with absolute value < 100. Follows C99
3397 standard. This is a change on Windows, which would use 3 digits.
3398 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3399 so that any alterations it does to the resulting string will be
3400 available in stringlib/formatter.h (for float.__format__).
3401
Eric Smith5a3c1352008-02-19 13:21:56 +00003402- Implemented PEP 3101, Advanced String Formatting. This adds a new
3403 builtin format(); a format() method for str and unicode; a
3404 __format__() method to object, str, unicode, int, long, float, and
3405 datetime; the class string.Formatter; and the C API
3406 PyObject_Format().
3407
Georg Brandl3ee81df2008-05-17 18:14:43 +00003408- Fixed several potential crashes, all caused by specially crafted
3409 __del__ methods exploiting objects in temporarily inconsistent
3410 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003411
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003412- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003413 prevent a possible crash: an Abstract Base Class would try to access
3414 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003415
Georg Brandl3ee81df2008-05-17 18:14:43 +00003416- Fixed repr() and str() of complex numbers with infinity or nan as
3417 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003418
Georg Brandl3ee81df2008-05-17 18:14:43 +00003419- Clear all free lists during a gc.collect() of the highest generation
3420 in order to allow pymalloc to free more arenas. Python may give back
3421 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003422
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423- Issue #2045: Fix an infinite recursion triggered when printing a
3424 subclass of collections.defaultdict, if its default_factory is set
3425 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003426
Christian Heimesf75dbef2008-02-08 00:11:31 +00003427- Fixed a minor memory leak in dictobject.c. The content of the free
3428 list was not freed on interpreter shutdown.
3429
Georg Brandl3ee81df2008-05-17 18:14:43 +00003430- Limit free list of method and builtin function objects to 256
3431 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003432
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3434 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003435 to compact the internal free lists of pre-allocted ints and floats.
3436
Georg Brandl3ee81df2008-05-17 18:14:43 +00003437- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3438 calls. Python expected the return type int but the fork familie
3439 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003440
Georg Brandl3ee81df2008-05-17 18:14:43 +00003441- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3442 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003443
Georg Brandl3ee81df2008-05-17 18:14:43 +00003444- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3445 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003446
Georg Brandl3ee81df2008-05-17 18:14:43 +00003447- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3448 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003449
Georg Brandl3ee81df2008-05-17 18:14:43 +00003450- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3451 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003452
Georg Brandl3ee81df2008-05-17 18:14:43 +00003453- Patch #1473257: generator objects gain a gi_code attribute. This is
3454 the same object as the func_code attribute of the function that
3455 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003456
Georg Brandl3ee81df2008-05-17 18:14:43 +00003457- Issue #1920: "while 0" statements were completely removed by the
3458 compiler, even in the presence of an "else" clause, which is
3459 supposed to be run when the condition is false. Now the compiler
3460 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003461
Guido van Rossumeead05f2008-01-24 18:21:02 +00003462- A few crashers fixed: weakref_in_del.py (issue #1377858);
3463 loosing_dict_ref.py (issue #1303614, test67.py);
3464 borrowed_ref_[34].py (not in tracker).
3465
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003466- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003467 suppressed while an extension is loaded by calling SetErrorMode in
3468 dynload_win.c. The error is still reported properly.
3469
Georg Brandl3ee81df2008-05-17 18:14:43 +00003470- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003471 several extension methods and modules do not work without unicode
3472 support.
3473
Georg Brandl26543b12008-01-21 18:36:51 +00003474- Issue #1882: when compiling code from a string, encoding cookies in the
3475 second line of code were not always recognized correctly.
3476
Georg Brandl14404b62008-01-19 19:27:05 +00003477- Issue #1679: "0x" was taken as a valid integer literal.
3478
Georg Brandl6caad7d2008-01-26 14:19:22 +00003479- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003480 added.
3481
Christian Heimesc94e2b52008-01-14 04:13:37 +00003482- sys.float_info / PyFloat_GetInfo: The floating point information
3483 object was converted from a dict to a specialized structseq object.
3484
Georg Brandl3ee81df2008-05-17 18:14:43 +00003485- Patch #1816: Added sys.flags structseq. It exposes the status of
3486 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003487
Georg Brandl3ee81df2008-05-17 18:14:43 +00003488- Objects/structseq.c: Implemented new structseq representation. The
3489 patch makes structseqs (e.g. the return value of os.stat) more
3490 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003491
Georg Brandl3ee81df2008-05-17 18:14:43 +00003492- Patch #1700288: added a type attribute cache that caches method
3493 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003494
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003495- Bug #1776: __import__() no longer accepts filenames on any platform.
3496 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003497
Georg Brandlaed6c662008-01-07 17:25:53 +00003498- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3499
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3501 envvar and sys.dont_write_bytecode attribute. All these can be set
3502 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003503
Georg Brandl3ee81df2008-05-17 18:14:43 +00003504- Improve some exception messages when Windows fails to load an
3505 extension module. Now we get for example '%1 is not a valid Win32
3506 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003507
Georg Brandl3ee81df2008-05-17 18:14:43 +00003508- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3511 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003512
Christian Heimes0a8143f2007-12-18 23:22:54 +00003513- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003514 and INF. float("nan"), float("inf") and float("-inf") now work on
3515 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003516
Georg Brandl3ee81df2008-05-17 18:14:43 +00003517- Compiler now generates simpler and faster code for dictionary
3518 literals. The oparg for BUILD_MAP now indicates an estimated
3519 dictionary size. There is a new opcode, STORE_MAP, for adding
3520 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003521
Georg Brandl3ee81df2008-05-17 18:14:43 +00003522- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003530- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003531 SystemError.
3532
Nick Coghlanef01d822007-12-03 12:55:17 +00003533- PEP 366: Allow explicit relative imports when executing modules

3535 __package__ attribute.
3536
Georg Brandl3ee81df2008-05-17 18:14:43 +00003537- Issue #1402: Fix a crash on exit, when another thread is still
3538 running, and if the deallocation of its frames somehow calls the
3539 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003540

3550 file can now be directly executed by passing their name to the
3551 interpreter. The directory/zipfile is automatically inserted as the
3552 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003553
Georg Brandl3ee81df2008-05-17 18:14:43 +00003554- Issue #1265: Fix a problem with sys.settrace, if the tracing
3555 function uses a generator expression when at the same time the
3556 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003557
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003558- sets and frozensets now have an isdisjoint() method.
3559
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003560- optimize the performance of builtin.sum().
3561
Neal Norwitz44f326e2007-10-05 05:29:17 +00003562- Fix warnings found by the new version of the Coverity checker.
3563
Georg Brandl3ee81df2008-05-17 18:14:43 +00003564- The enumerate() builtin function is no longer bounded to sequences
3565 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3566 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003567
Georg Brandl3ee81df2008-05-17 18:14:43 +00003568- Issue #1686386: Tuple's tp_repr did not take into account the
3569 possibility of having a self-referential tuple, which is possible
3570 from C code. Nor did object's tp_str consider that a type's tp_str
3571 could do something that could lead to an inifinite recursion.
3572 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3573 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003574
Georg Brandl3ee81df2008-05-17 18:14:43 +00003575- Issue #1164: It was possible to trigger deadlock when using the
3576 'print' statement to write to a file since the GIL was not released
3577 as needed. Now PyObject_Print() does the right thing along with
3578 various tp_print implementations of the built-in types and those in
3579 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003580
Georg Brandl3ee81df2008-05-17 18:14:43 +00003581- Issue #1147: Exceptions were directly allowing string exceptions in
3582 their throw() method even though string exceptions no longer
3583 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003584
Georg Brandl3ee81df2008-05-17 18:14:43 +00003585- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003588- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003589 PyObject_Call() never calling back out to Python code to trigger
3590 recursion depth updates/checks. Required the creation of a static
3591 RuntimeError instance in case normalizing an exception put the
3592 recursion check value past its limit. Fixes crashers
3593 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003594

Neal Norwitz0ac60192007-05-27 04:08:54 +00003608- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003609 __*__ attributes. (Some already existed, e.g., __doc__ and
3610 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003611
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003612- Add -3 option to the interpreter to warn about features that are
3613 deprecated and will be changed/removed in Python 3.0.
3614
Georg Brandl2134e752007-05-21 20:34:16 +00003615- Patch #1686487: you can now pass any mapping after '**' in function
3616 calls.
3617
Collin Winter62903052007-05-18 23:11:24 +00003618- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003619 "except E as target:". This is to provide forwards compatibility
3620 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003621
Brett Cannon229cee22007-05-05 01:34:02 +00003622- Deprecate BaseException.message as per PEP 352.
3623
Georg Brandl3ee81df2008-05-17 18:14:43 +00003624- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003625 inherited from a builtin base.
3626
Vinay Sajip8549ce32007-05-06 17:53:37 +00003627- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003628 setting a plain string, ie don't expand to single letter identifiers.
3629
Raymond Hettinger13936692007-04-11 18:40:58 +00003630- Request #1191699: Slices can now be pickled.
3631
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003632- Request #1193128: str.translate() now allows a None argument for
3633 translations that only remove characters without re-mapping the
3634 remaining characters.
3635
Georg Brandl5cb76c12007-03-21 09:00:39 +00003636- Patch #1682205: a TypeError while unpacking an iterable is no longer

3640
Guido van Rossum143b5642007-03-23 04:58:42 +00003641- Bug #1683368: The object.__init__() and object.__new__() methods are
3642 now stricter in rejecting excess arguments. The only time when
3643 either allows excess arguments is when it is not overridden and the
3644 other one is. For backwards compatibility, when both are
3645 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003646 warning later). Also, type.__init__() insists on the same signature
3647 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003648
Georg Brandl3ee81df2008-05-17 18:14:43 +00003649- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3650 object to complex using its __complex__() method before falling back
3651 to the __float__() method. Therefore, the functions in the cmath
3652 module now can operate on objects that define a __complex__()
3653 method.

3657 same slot names.

3670
Georg Brandl7b9c5552007-03-12 14:30:05 +00003671- Bug #1678647: write a newline after printing an exception in any
3672 case, even when converting the value to a string failed.
3673
Georg Brandl871f1bc2007-03-12 13:17:36 +00003674- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003675 its argument, if it exists. If not, it will work like before. This
3676 allows customizing the output of dir() in the presence of a
3677 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003678
Collin Winter276887b2007-03-12 16:11:39 +00003679- Patch #922167: Python no longer segfaults when faced with infinitely
3680 self-recursive reload() calls (as reported by bug #742342).
3681
Georg Brandl3ee81df2008-05-17 18:14:43 +00003682- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003685- Patch #1491866: change the complex() constructor to allow
3686 parthensized forms. This means complex(repr(x)) now works instead of
3687 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003688
Georg Brandlaa2321b2007-03-07 00:40:28 +00003689- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003690 makes the filenames the warning module prints much more sensible
3691 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003692
Georg Brandl49aafc92007-03-07 00:34:46 +00003693- Variant of patch #697613: don't exit the interpreter on a SystemExit
3694 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003695 variable is given, but break into the interactive interpreter just
3696 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00003703
Georg Brandl0fca97a2007-03-05 22:28:08 +00003704- Patch #1674228: when assigning a slice (old-style), check for the
3705 sq_ass_slice instead of the sq_slice slot.
3706
Georg Brandl3ee81df2008-05-17 18:14:43 +00003707- When printing an unraisable error, don't print exceptions. before
3708 the name. This duplicates the behavior whening normally printing
3709 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003710

Georg Brandl3ee81df2008-05-17 18:14:43 +00003717- Bug #1377858: Fix the segfaulting of the interpreter when an object
3718 created a weakref on itself during a __del__ call for new-style
3719 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004242 AttributeError instead of an IOError when the server's response
4243 didn't contain a valid HTTP status line.

4275
Georg Brandl92a6bae2007-03-13 17:43:32 +00004276- Patch #1603688: ConfigParser.SafeConfigParser now checks values that

4334 TestCase and TestSuite subclasses (not instances) are no longer
4335 accepted in TestSuite.addTest(). This should cause no

4617 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004618
Georg Brandl3ee81df2008-05-17 18:14:43 +00004619- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4620 with RFC 3207 and forgets any knowledge obtained from the server not
4621 obtained from the TLS negotiation itself. Patch contributed by Bill
4622 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004623
Georg Brandl3ee81df2008-05-17 18:14:43 +00004624- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004625 that the SMTP.starttls() caller no longer needs to call ehlo()
4626 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004627 does not claim to support starttls. Adds the
4628 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4709 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4710 silently miscode subclasses of those types. Now, it raises a
4711 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004712

Georg Brandl3ee81df2008-05-17 18:14:43 +00004727 time so that opening a database previously created with the DB_DUP
4728 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4729 opens. Specifically: dictionary assignment to a DB object will
4730 replace all values for a given key when the database allows
4731 duplicate values. DB users should use DB.put(k, v) when they want
4732 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004733

4739 characters with ASCII value less than 32. Also, it correctly quotes
4740 dots only if they occur on a single line, as opposed to the previous
4741 behavior of quoting dots if they are the second character of any
4742 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004743

5080 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005081
5082- Patch #1720595: add T_BOOL to the range of structmember types.
5083
5084- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5085 ``PyFloat_GetInfo()`` to the float API.
5086
Georg Brandl3ee81df2008-05-17 18:14:43 +00005087- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5088 of w# format code incorrectly truncated the length to an int, even
5089 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5090 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005091
Georg Brandl3ee81df2008-05-17 18:14:43 +00005092- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5093 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005095- PEP 3123: Provide forward compatibility with Python 3.0, while
5096 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5097 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005098
Georg Brandl3ee81df2008-05-17 18:14:43 +00005099- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5100 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005101
5102- Patch #1733960: Allow T_LONGLONG to accept ints.
5103
5104- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5105
Christian Heimes000a0742008-01-03 22:16:32 +00005106- Added a new API function ``PyImport_ImportModuleNoBlock``.

Georg Brandl6caad7d2008-01-26 14:19:22 +00005108- Bug #1637022: Prefix AST symbols with _Py_.
5109
5110- Fix some leftovers from the conversion from int to Py_ssize_t
5111 (relevant to strings and sequences of more than 2**31 items).
5112
5113- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5114 outside of pystate.c and should not be necessary.
5115
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5117 absolute imports. In earlier versions they might have used relative
5118 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005119
Georg Brandl3ee81df2008-05-17 18:14:43 +00005120- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5121 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005122
Georg Brandl3ee81df2008-05-17 18:14:43 +00005123- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5124 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005130- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5131 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5132 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5133 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005148- Removed the macfs module. It had been deprecated since Python 2.5.
5149 This lead to the deprecation of macostools.touched() as it relied
5150 solely on macfs and was a no-op under OS X.
