34Core and Builtins
35-----------------
36
Benjamin Petersonecdae192010-01-04 00:43:01 +000037- The __complex__ method is now looked up on the class of instances to make it
38 consistent with other special methods.
39
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000040- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
41 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
42
Mark Dickinson1b34d252010-01-01 17:27:30 +000043- Issue #5080: A number of functions and methods previously produced a
44 DeprecationWarning when passed a float argument where an integer was
45 expected. These functions and methods now raise TypeError instead.
46 The majority of the effects of this change are in the extension
47 modules, but some core functions and methods are affected: notably
48 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
49 methods.
50
Benjamin Peterson0f02d392009-12-30 19:34:10 +000051- Issue #7604: Deleting an unset slotted attribute did not raise an
52 AttributeError.
53
Mark Dickinson99d652e2009-12-30 12:12:23 +000054- Issue #7534: Fix handling of IEEE specials (infinities, nans,
55 negative zero) in ** operator. The behaviour now conforms to that
56 described in C99 Annex F.
57
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000058- Issue #7579: the msvcrt module now has docstrings for all its functions.
59
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000060- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
61 used to drop the time part of the result.
62
Mark Dickinson46572832009-12-27 14:55:57 +000063- Issue #1811: improve accuracy and cross-platform consistency for
64 true division of integers: the result of a/b is now correctly
65 rounded for ints a and b (at least on IEEE 754 platforms), and in
66 particular does not depend on the internal representation of a long.
67
Ezio Melottif84caf42009-12-24 22:25:17 +000068- Issue #6108: unicode(exception) and str(exception) should return the same
69 message when only __str__ (and not __unicode__) is overridden in the subclass.
70
Ronald Oussoren92919a62009-12-24 13:30:58 +000071- Issue #6834: replace the implementation for the 'python' and 'pythonw'
72 executables on OSX.
73
74 These executables now work properly with the arch(1) command:
75 ``arch -ppc python`` will start a universal binary version of python
76 in PPC mode (unlike previous releases).
77
R. David Murray0a0a1a82009-12-14 16:28:26 +000078- Issue #1680159: unicode coercion during an 'in' operation no longer masks
79 the underlying error when the coercion fails for the left hand operand.
80
Benjamin Peterson4895af42009-12-13 16:36:53 +000081- Issue #7491: Metaclass's __cmp__ method was ignored.

Antoine Pitrou2a08b422009-12-13 16:18:14 +000083- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +000084 in the middle of populating a tuple. Patch by Florent Xicluna.

91 gcc when it has a fully qualified configuration prefix. Initial patch
92 by Arfrever.
93
Antoine Pitrou80157252010-01-08 19:20:17 +000094- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
95 renaming of `cPickle` to `pickle`. The warning was annoying since there's
96 no alternative to cPickle if you care about performance. Patch by Florent
97 Xicluna.
98
Antoine Pitrou0d423b82010-01-07 17:46:49 +000099- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

Antoine Pitrou673ddf92010-01-03 22:29:56 +0000105- Issue #7471: Improve the performance of GzipFile's buffering mechanism,
106 and make it implement the `io.BufferedIOBase` ABC to allow for further
107 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
108
109- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000110 parameter to allow specifying where your connections come from.
111

Senthil Kumaran7713acf2009-12-20 06:05:13 +0000128 Patch by Tatsuhiro Tsujikawa.
129
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000130- Issue #7349: Make methods of file objects in the io module accept None as an
131 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
132 the same as passing no argument.
133
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000134- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
135 like other file objects.
136

143 missing proper end-of-line termination.
144
Tarek Ziadé2421d562009-12-20 23:23:34 +0000145- Issue #7457: added a read_pkg_file method to
Tarek Ziadéa939ecd2009-12-08 08:56:49 +0000146 distutils.dist.DistributionMetadata.

204
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000205- Issue #7419: setlocale() could crash the interpreter on Windows when called
206 with invalid values.
207
Eric Smithc4ab8332009-11-29 17:40:57 +0000208- Issue #3382: 'F' formatting for float and complex now convert the
209 result to upper case. This only affects 'inf' and 'nan', since 'f'
210 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000211
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000212- Remove switch from "%f" formatting to "%g" formatting for floats
213 larger than 1e50 in absolute value.
214
Mark Dickinson18cfada2009-11-23 18:46:41 +0000215- Remove restrictions on precision when formatting floats. E.g.,
216 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
217 requested 120 significant digits instead.
218
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000219- Add Py3k warnings for parameter names in parenthesis.
220
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000221- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000222
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000223- Issue #7085: Fix crash when importing some extensions in a thread
224 on MacOSX 10.6.
225
Mark Dickinsonb678de82009-11-19 18:41:49 +0000226- Issue #7117: repr(x) for a float x returns a result based on the
227 shortest decimal string that's guaranteed to round back to x under
228 correct rounding (with round-half-to-even rounding mode).
229 Previously it gave a string based on rounding x to 17 decimal digits.
230 repr(x) for a complex number behaves similarly. On platforms where
231 the correctly-rounded strtod and dtoa code is not supported (see below),
232 repr is unchanged.
233
234- Issue #7117: On almost all platforms: float-to-string and
235 string-to-float conversions within Python are now correctly rounded.
236 Places these conversions occur include: str for floats and complex
237 numbers; the float and complex constructors; old-style and new-style
238 numeric formatting; serialization and deserialization of floats and
239 complex numbers using marshal, pickle and json; parsing of float and
240 imaginary literals in Python code; Decimal-to-float conversion.
241
242 The conversions use a Python-adapted version of David Gay's
243 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
244 functions. This code is supported on Windows, and on Unix-like
245 platforms using gcc, icc or suncc as the C compiler. There may be a
246 small number of platforms on which correct operation of this code
247 cannot be guaranteed, so the code is not used: notably, this applies
248 to platforms where the C double format is not IEEE 754 binary64, and
249 to platforms on x86 hardware where the x87 FPU is set to 64-bit
250 precision and Python's configure script is unable to determine how
251 to change the FPU precision. On these platforms conversions use the
252 platform strtod and dtoa, as before.
253
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000254- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000255 now uses the correctly-rounded string <-> float conversions
256 described above (when available), and so produces correctly rounded
257 results that will display nicely under the float repr. There are
258 two related small changes: (1) round now accepts any class with an
259 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000260 floats for the second argument), and (2) an excessively large second
261 integer argument (e.g., round(1.234, 10**100)) no longer raises an
262 exception.
263
Philip Jenveyfab8be22009-11-17 02:42:26 +0000264- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
265
Benjamin Petersone36199b2009-11-12 23:39:44 +0000266- Fix several issues with compile(). The input can now contain Windows and Mac
267 newlines and is no longer required to end in a newline.
268
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000269- Remove length limitation when constructing a complex number from a
270 unicode string.
271
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000272- Issue #7244: itertools.izip_longest() no longer ignores exceptions
273 raised during the formation of an output tuple.
274

391 statement and correctly lookup the __enter__ and __exit__ special methods.
392
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000393- Issue #5829: complex("1e500") no longer raises OverflowError. This

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000404- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
405 (1) inf and nan strings with trailing whitespace were incorrectly
406 rejected; (2) parsing of strings representing infinities and nans
407 was locale aware; and (3) the interpretation of fromhex('-nan')
408 didn't match that of float('-nan').
409
Eric Smitha985a3a2009-05-05 18:26:08 +0000410- Issue #5920: For float.__format__, change the behavior with the
411 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
412 to be like 'g' but with at least one decimal point and with a
413 default precision of 12. Previously, the behavior the same but with
414 a default precision of 6. This more closely matches str(), and
415 reduces surprises when adding alignment flags to the empty
416 presentation type. This also affects the new complex.__format__ in
417 the same way.
418
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000419- Issue #5890: in subclasses of 'property' the __doc__ attribute was

482 untrackable objects are not tracked by the garbage collector. This can
483 reduce the size of collections and therefore the garbage collection overhead
484 on long-running programs, depending on their particular use of datatypes.
485
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000486- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

491 2**15 for the internal representation of integers, for performance
492 reasons. Base 2**30 is enabled by default on 64-bit machines. Add

519 on a 64-bit system.
520
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000521- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

528
Georg Brandl29c6a282009-04-05 20:23:13 +0000529- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000530 were suppressing all exceptions. These include list(), filter(), map(),

Mark Dickinson826f3fe2008-12-05 21:55:28 +0000604- Issue #4445: Replace "sizeof(PyStringObject)" with
605 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
606 str instances. On a typical machine this saves 3 bytes of memory
607 (on average) per string allocation.
608
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000609- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
610 interpreter to abort ("Fatal Python error: Could not reset the stack!")
611 instead of throwing a MemoryError.
612
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000613- Issue #3689: The list reversed iterator now supports __length_hint__

Vinay Sajip213faca2008-12-03 23:22:58 +0000619- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000620 method on file objects with closefd=False. The file descriptor is still
621 kept open but the file object behaves like a closed file. The ``FileIO``
622 object also got a new readonly attribute ``closefd``.

641
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000642- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000643 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000644
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000645- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
646 returned a path longer than MAX_PATH. (But It's doubtful this code path is
647 really executed because I cannot move to such directory on win2k)
648
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000649- Issue #4069: When set.remove(element) is used with a set element, the element
650 is temporarily replaced with an equivalent frozenset. But the eventual
651 KeyError would always report the empty frozenset([]) as the missing key. Now
652 it correctly refers to the initial element.
653

670 returned them on 64bit platforms.
671
Walter Dörwalded960ac2009-05-03 22:36:33 +0000672- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
673 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
674 step. This avoids problems with counting UTF-8 bytes that ignores the effect
675 of using the replace error handler in PyUnicode_DecodeUTF8().
676
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000677- Issue #3739: The unicode-internal encoder now reports the number of characters
678 consumed like any other encoder (instead of the number of bytes).
679
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000680- Issue #2422: When compiled with the ``--with-valgrind`` option, the
681 pymalloc allocator will be automatically disabled when running under
682 Valgrind. This gives improved memory leak detection when running
683 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +0000752- Issue #6816: runpy now provides a run_path function that allows Python code
753 to execute file paths that refer to source or compiled Python files as well
754 as zipfiles, directories and other valid sys.path entries that contain a

1920 leak-chasing test runs give sensible results. The previous method of

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002063- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2064
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002065- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2066 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2067 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2068 ``printf`` function, whereas PyString_FromFormat has an independent
2069 implementation and uses "%zd" on all platforms for size_t values.
2070 This makes a difference on win64, where ``printf`` needs "%Id" to display
2071 64bit values.
2072
Benjamin Peterson97179b02008-09-09 20:55:01 +00002073- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2077 object; previously an int would be returned for small values. the __long__
2078 method is allowed to return either an int or a long, but the behaviour of
2079 float objects should not change to respect backward compatibility.
2080
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002081- Issue #3751: str.rpartition would perform a left-partition when called with
2082 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002087 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002088 was correctly parsed but parsing of subsequent arguments failed.
2089
Vinay Sajip35e3b032008-09-01 14:33:59 +00002090- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002091 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2092 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2093 when given a tuple of classes as second argument, were looking up
2094 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2095 type object.
2096
Neal Norwitz18aa3882008-08-24 05:04:52 +00002097- Fix crashes on memory allocation failure found with failmalloc.

2166 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2167 for catch_warnings() also led to an improvement in the raising of a

2240-----------------
2241
Guido van Rossumf8402962008-08-20 15:01:50 +00002242- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2243 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2244 extensions do not automatically benefit from the class attribute
2245 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2246 to their tp_flags field if they care. This is a backwards
2247 compatibility feature; in 3.0, all types will use the cache by
2248 default.
2249
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002250- Keyword arguments can now follow starred arguments. (``f(a, *args,
2251 keyword=23)`` is now valid syntax.)
2252
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002253- ctypes function pointers that are COM methods have a boolean True
2254 value again.
2255
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002256- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2257 by denying s# to parse objects that have a releasebuffer procedure,
2258 and introducing s*.
2259
Georg Brandl1e13ea92008-08-11 09:07:59 +00002260- Issue #3537: Fix an assertion failure when an empty but presized dict
2261 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00002263- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2264 ValueError consistently across platforms.
2265
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002266- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2267 (64bit Unix, for example), unichr() would truncate its argument and return
2268 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2269
Neal Norwitze7d8be82008-07-31 17:17:14 +00002270- Apply security patches from Apple.
2271
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002272- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00002275- Issue #1819: function calls with several named parameters are now on
2276 average 35% faster (as measured by pybench).
2277
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002278- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2279 the python debugger steps into a class statement: the free variables (local
2280 variables defined in an outer scope) would be deleted from the outer scope.
2281
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002282- Issue #2620: Overflow checking when allocating or reallocating memory
2283 was not always being done properly in some python types and extension
2284 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2285 all been updated to perform better checks and places in the code that
2286 would previously leak memory on the error path when such an allocation
2287 failed have been fixed.

2293
Benjamin Petersone977ad42008-08-20 01:42:01 +00002294- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2295 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2296
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002297- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2298 version reported by these tools does not necessarily follow the python
2299 version numbering scheme, so the module is less strict when parsing it.
2300
Nick Coghlanf70385a2008-08-18 12:42:46 +00002301- Issue #2235: Added Py3k warnings for types which will become unhashable
2302 under the stricter __hash__ inheritance rules in 3.0. Several types
2303 which did not meet the rules for hash invariants and were already
2304 unhashable in 3.0 have now been explicitly flagged as unhashable in
2305 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2306 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2307
Brett Cannon88f801d2008-08-18 00:46:22 +00002308- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2309 imported into the module but exposed as part of the module's API.
2310

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002317- Issue #3575: Incremental decoder's decode function now takes bytearray
2318 by using 's*' instead of 't#'.
2319
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002320- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002321 fails unicode conversion on 2nd parameter. (windows only)
2322
Facundo Batista94f243a2008-08-17 03:38:39 +00002323- Issue 2464. urllib2 now supports a malformation in the URL received
2324 in a redirect.

Facundo Batistaeb90b782008-08-16 14:44:07 +00002329- Issue #2776: fixed small issue when handling an URL with double slash
2330 after a 302 response in the case of not going through a proxy.
2331
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002332- Issue #2676: in the email package, content-type parsing was hanging on
2333 pathological input because of quadratic or exponential behaviour of a
2334 regular expression.
2335
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002336- Issue #3476: binary buffered reading through the new "io" library is now
2337 thread-safe.
2338
Brett Cannonbf3157b2008-08-14 05:00:03 +00002339- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2340 since mimetools itself is deprecated. Because modules are cached, all
2341 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2342
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002343- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002345- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2346 menu entries were not deleted.
2347
Brett Cannon83e81842008-08-09 23:30:55 +00002348- Copied the implementation of reduce() to _functools.reduce() to have a
2349 version that did not raise a DeprecationWarning under -3.
2350
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002351- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2352 a MemoryError rather than silently stop the iteration.
2353
Guido van Rossum59ce9012008-08-09 14:55:34 +00002354- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2355 to _sre.compile() will now be rejected. This should not affect anybody
2356 since the re.compile() function never generates invalid re-bytecode.
2357
Skip Montanaroa032bf42008-08-08 22:52:51 +00002358- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2359 upon first access it can be automatically initialized from the csv file if
2360 it wasn't initialized during instantiation.
2361
Brett Cannon3aa2a492008-08-06 22:28:09 +00002362- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2363 the reload() built-in has been removed.
2364
Brett Cannon7e30b672008-08-04 21:52:25 +00002365- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002366 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2374 raised an AttributeError.
2375
Benjamin Peterson01a24322008-07-28 23:35:27 +00002376- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002377 asking for a specific length. This problem only affected files opened
2378 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002379
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002380- Issue #3449: Update decimal module to use most recent specification
2381 (v. 1.68) and tests (v. 2.58) from IBM.
2382

2402
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002403- Issue #3394: zipfile.writestr sets external attributes when passed a
2404 file name rather than a ZipInfo instance, so files are extracted with
2405 mode 0600 rather than 000 under Unix.
2406
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002407- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2408 argument in python 2.5, this broke code that subclassed Popen to include its
2409 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2417-------------
2418
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002419- Issue #2235: the C API function PyObject_HashNotImplemented and its
2420 interaction with the tp_hash slot (added in 2.6b2) are now documented
2421
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002422- Issue #643841: The language reference now provides more detailed
2423 coverage of the lookup process for special methods. The disclaimers
2424 regarding lack of coverage of new-style classes have also been
2425 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002428What's New in Python 2.6 beta 2?
2429================================
2430
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002431*Release date: 17-Jul-2008*
2432
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002433Core and Builtins
2434-----------------
2435
Georg Brandl3e483f62008-07-16 22:57:41 +00002436- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2437 its methods now allow for items objects that can be converted to
2438 an integer using operator.index().
2439
Mark Dickinson64b7e502008-07-16 09:40:03 +00002440- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2441 produced a ValueError instead of giving the correct float.
2442
Eric Smitha5fa5a22008-07-16 00:11:49 +00002443- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2444 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2445
Mark Dickinson7103aa42008-07-15 19:08:33 +00002446- Issue #3008: the float type has a new instance method 'float.hex'
2447 and a new class method 'float.fromhex' to convert floating-point
2448 numbers to and from hexadecimal strings, respectively.
2449
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002450- Issue #2235: __hash__ is once again inherited by default. To allow
2451 collections.Hashable to remain meaningful in the presence of the
2452 default hash implementation (object.__hash__), it is now possible
2453 to explicit block inheritance of hash by setting __hash__=None at
2454 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2455 level.
2456
Nick Coghlanb028f502008-07-13 14:52:36 +00002457- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2458 the parent module cannot be found while performing an absolute import.
2459 This means that an incorrectly defined __package__ attribute will
2460 now only prevent relative imports in that module rather than causing
2461 all imports from that module to fail.
2462
Nick Coghlan14ff9942008-07-08 14:21:42 +00002463- Issue #2517: Allow unicode messages in Exceptions again by correctly
2464 bypassing the instance dictionary when looking up __unicode__ on
2465 new-style classes.
2466
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002467- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2468 set to a custom object whose write() method happens to install
2469 another file in sys.stdout.
2470
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002471- Issue #3088: Corrected a race condition in classes derived from
2472 threading.local: the first member set by a thread could be saved in
2473 another thread's dictionary.
2474
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002475- Issue #3004: Minor change to slice.indices(): the start and stop
2476 arguments are now treated identically, making the behaviour easier
2477 to describe and understand. For example, slice(None, -10,
2478 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2479 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2480 10, -1).
2481
Georg Brandl278fc502008-07-19 12:46:12 +00002482- Issue #3219: Calling a function with repeated keyword arguments,
2483 f(a=2, a=23), would not cause a syntax error. This was a regression
2484 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002485
Georg Brandl278fc502008-07-19 12:46:12 +00002486- Issue #2862: Make int and float freelist management consistent with
2487 other freelists. Changes their CompactFreeList apis into
2488 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002489

2491-------
2492
Thomas Heller57adf222008-08-14 19:10:48 +00002493- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2494 api functions without holding the GIL, which could lead to a fatal
2495 error when they failed.
2496
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002497- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002505- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2506 ForkingPickler.register() to resolve conflict with ctypes.
2507
Vinay Sajip51e65192008-07-18 09:01:10 +00002508- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002509
Thomas Heller880f5292008-07-15 19:39:38 +00002510- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2511 a valid dlerror() message.
2512
Thomas Heller2bad6572008-07-15 17:19:50 +00002513- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2514 incomplete structure was created.
2515
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002516- Issue #3339: dummy_thread.acquire() should not return None.
2517
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002518- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2519
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002520- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002521
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002522- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2523 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002524 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002525 content-length. The problem had been corrected in the 2.4 branch, but never
2526 merged into trunk.
2527
Georg Brandle78fbcc2008-07-05 10:13:36 +00002528- Issue #2663: add filtering capability to shutil.copytree().

2534- Issue #1746: Correct handling of zipfile archive comments (previously
2535 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002536 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002537
Vinay Sajip51e65192008-07-18 09:01:10 +00002538- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002539 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002540
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002541- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2542 handling is now the same as that of other special attributes like __name__).
2543
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002544- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2545 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00002934 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002935
2936 This is controlled by the configure argument ``--with-universal-archs``:
2937
2938 - ``--with-universal-archs=all``: install 4-way universal
2939
2940 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2941
2942 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2943
2944 This option should be used in combination with ``--enable-universalsdk=``.
2945
2946 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 +00002996- Issue #1631171: Re-implement the 'warnings' module in C (the
2997 original Python code has been kept as backup). This will allow for
2998 using the 'warning's machinery in such places as the parser where
2999 use of pure Python code is not possible. Both the ``showarning()``
3000 and ``formatwarning()`` gain an optional 'line' argument which is
3001 not called by default for backwards-compatibility reasons. Setting
3002 ``warnings.showwarning()`` to an implementation that lacks support
3003 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003066- Issue #2550: The approach used by client/server code for obtaining
3067 ports to listen on in network-oriented tests has been refined in an
3068 effort to facilitate running multiple instances of the entire
3069 regression test suite in parallel without issue.
3070 test_support.bind_port() has been fixed such that it will always
3071 return a unique port -- which wasn't always the case with the
3072 previous implementation, especially if socket options had been set
3073 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3074 new implementation of bind_port() will actually raise an exception
3075 if it is passed an AF_INET/SOCK_STREAM socket with either the
3076 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3077 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3078 the socket it's been passed. This currently only applies to
3079 Windows. This option prevents any other sockets from binding to the
3080 host/port we've bound to, thus removing the possibility of the
3081 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3082 when a second SOCK_STREAM socket binds and accepts to a host/port
3083 that's already been bound by another socket. The optional preferred
3084 port parameter to bind_port() has been removed. Under no
3085 circumstances should tests be hard coding ports!
3086
3087 test_support.find_unused_port() has also been introduced, which will
3088 pass a temporary socket object to bind_port() in order to obtain an
3089 unused port. The temporary socket object is then closed and
3090 deleted, and the port is returned. This method should only be used
3091 for obtaining an unused port in order to pass to an external program
3092 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3093 a parameter to a server-oriented class that doesn't give you direct
3094 access to the underlying socket used.
3095
3096 Finally, test_support.HOST has been introduced, which should be used
3097 for the host argument of any relevant socket calls (i.e. bind and
3098 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003099
3100 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003101 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3374
Fred Drakea8ee94b2008-03-01 02:45:07 +00003375- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003376 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003377
Georg Brandlad61bc82008-02-23 15:11:18 +00003378- Issue #2067: file.__exit__() now calls subclasses' close() method.
3379
3380- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003381
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003382- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003383 issue 215555 for a discussion.
3384
Eric Smitha73fbe72008-02-23 03:09:44 +00003385- Added the future_builtins module, which contains hex() and oct().
3386 These are the PEP 3127 version of these functions, designed to be
3387 compatible with the hex() and oct() builtins from Python 3.0. They
3388 differ slightly in their output formats from the existing, unchanged
3389 Python 2.6 builtins. The expected usage of the future_builtins
3390 module is:
3391 from future_builtins import hex, oct
3392
Eric Smith7ef40bf2008-02-20 23:34:22 +00003393- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3394 exponents for exponents with absolute value < 100. Follows C99
3395 standard. This is a change on Windows, which would use 3 digits.
3396 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3397 so that any alterations it does to the resulting string will be
3398 available in stringlib/formatter.h (for float.__format__).
3399
Eric Smith5a3c1352008-02-19 13:21:56 +00003400- Implemented PEP 3101, Advanced String Formatting. This adds a new
3401 builtin format(); a format() method for str and unicode; a
3402 __format__() method to object, str, unicode, int, long, float, and
3403 datetime; the class string.Formatter; and the C API
3404 PyObject_Format().
3405
Georg Brandl3ee81df2008-05-17 18:14:43 +00003406- Fixed several potential crashes, all caused by specially crafted
3407 __del__ methods exploiting objects in temporarily inconsistent
3408 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003409
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003410- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003411 prevent a possible crash: an Abstract Base Class would try to access
3412 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003413
Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Fixed repr() and str() of complex numbers with infinity or nan as
3415 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003416
Georg Brandl3ee81df2008-05-17 18:14:43 +00003417- Clear all free lists during a gc.collect() of the highest generation
3418 in order to allow pymalloc to free more arenas. Python may give back
3419 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003420
Georg Brandl3ee81df2008-05-17 18:14:43 +00003421- Issue #2045: Fix an infinite recursion triggered when printing a
3422 subclass of collections.defaultdict, if its default_factory is set
3423 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003424
Christian Heimesf75dbef2008-02-08 00:11:31 +00003425- Fixed a minor memory leak in dictobject.c. The content of the free
3426 list was not freed on interpreter shutdown.
3427
Georg Brandl3ee81df2008-05-17 18:14:43 +00003428- Limit free list of method and builtin function objects to 256
3429 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003430
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3432 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003433 to compact the internal free lists of pre-allocted ints and floats.
3434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3436 calls. Python expected the return type int but the fork familie
3437 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003438
Georg Brandl3ee81df2008-05-17 18:14:43 +00003439- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3440 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003441
Georg Brandl3ee81df2008-05-17 18:14:43 +00003442- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3443 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003444
Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3446 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003447
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3449 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003450
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451- Patch #1473257: generator objects gain a gi_code attribute. This is
3452 the same object as the func_code attribute of the function that
3453 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003454
Georg Brandl3ee81df2008-05-17 18:14:43 +00003455- Issue #1920: "while 0" statements were completely removed by the
3456 compiler, even in the presence of an "else" clause, which is
3457 supposed to be run when the condition is false. Now the compiler
3458 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003459
Guido van Rossumeead05f2008-01-24 18:21:02 +00003460- A few crashers fixed: weakref_in_del.py (issue #1377858);
3461 loosing_dict_ref.py (issue #1303614, test67.py);
3462 borrowed_ref_[34].py (not in tracker).
3463
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003464- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003465 suppressed while an extension is loaded by calling SetErrorMode in
3466 dynload_win.c. The error is still reported properly.
3467
Georg Brandl3ee81df2008-05-17 18:14:43 +00003468- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003469 several extension methods and modules do not work without unicode
3470 support.
3471
Georg Brandl26543b12008-01-21 18:36:51 +00003472- Issue #1882: when compiling code from a string, encoding cookies in the
3473 second line of code were not always recognized correctly.
3474
Georg Brandl14404b62008-01-19 19:27:05 +00003475- Issue #1679: "0x" was taken as a valid integer literal.
3476
Georg Brandl6caad7d2008-01-26 14:19:22 +00003477- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003478 added.
3479
Christian Heimesc94e2b52008-01-14 04:13:37 +00003480- sys.float_info / PyFloat_GetInfo: The floating point information
3481 object was converted from a dict to a specialized structseq object.
3482
Georg Brandl3ee81df2008-05-17 18:14:43 +00003483- Patch #1816: Added sys.flags structseq. It exposes the status of
3484 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003485
Georg Brandl3ee81df2008-05-17 18:14:43 +00003486- Objects/structseq.c: Implemented new structseq representation. The
3487 patch makes structseqs (e.g. the return value of os.stat) more
3488 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003489
Georg Brandl3ee81df2008-05-17 18:14:43 +00003490- Patch #1700288: added a type attribute cache that caches method
3491 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003492
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003493- Bug #1776: __import__() no longer accepts filenames on any platform.
3494 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003495
Georg Brandlaed6c662008-01-07 17:25:53 +00003496- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3497
Georg Brandl3ee81df2008-05-17 18:14:43 +00003498- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3499 envvar and sys.dont_write_bytecode attribute. All these can be set
3500 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003501
Georg Brandl3ee81df2008-05-17 18:14:43 +00003502- Improve some exception messages when Windows fails to load an
3503 extension module. Now we get for example '%1 is not a valid Win32
3504 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003505
Georg Brandl3ee81df2008-05-17 18:14:43 +00003506- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003508- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3509 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003510
Christian Heimes0a8143f2007-12-18 23:22:54 +00003511- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003512 and INF. float("nan"), float("inf") and float("-inf") now work on
3513 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003514
Georg Brandl3ee81df2008-05-17 18:14:43 +00003515- Compiler now generates simpler and faster code for dictionary
3516 literals. The oparg for BUILD_MAP now indicates an estimated
3517 dictionary size. There is a new opcode, STORE_MAP, for adding
3518 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003519
Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Issue #1638: %zd configure test fails on Linux.

3536 running, and if the deallocation of its frames somehow calls the
3537 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003538

3548 file can now be directly executed by passing their name to the
3549 interpreter. The directory/zipfile is automatically inserted as the
3550 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003551
Georg Brandl3ee81df2008-05-17 18:14:43 +00003552- Issue #1265: Fix a problem with sys.settrace, if the tracing
3553 function uses a generator expression when at the same time the
3554 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003555
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003556- sets and frozensets now have an isdisjoint() method.
3557
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003558- optimize the performance of builtin.sum().
3559
Neal Norwitz44f326e2007-10-05 05:29:17 +00003560- Fix warnings found by the new version of the Coverity checker.
3561
Georg Brandl3ee81df2008-05-17 18:14:43 +00003562- The enumerate() builtin function is no longer bounded to sequences
3563 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3564 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003565
Georg Brandl3ee81df2008-05-17 18:14:43 +00003566- Issue #1686386: Tuple's tp_repr did not take into account the
3567 possibility of having a self-referential tuple, which is possible
3568 from C code. Nor did object's tp_str consider that a type's tp_str
3569 could do something that could lead to an inifinite recursion.
3570 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3571 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003572
Georg Brandl3ee81df2008-05-17 18:14:43 +00003573- Issue #1164: It was possible to trigger deadlock when using the
3574 'print' statement to write to a file since the GIL was not released
3575 as needed. Now PyObject_Print() does the right thing along with
3576 various tp_print implementations of the built-in types and those in
3577 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003578
Georg Brandl3ee81df2008-05-17 18:14:43 +00003579- Issue #1147: Exceptions were directly allowing string exceptions in
3580 their throw() method even though string exceptions no longer
3581 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003582
Georg Brandl3ee81df2008-05-17 18:14:43 +00003583- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003586- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003587 PyObject_Call() never calling back out to Python code to trigger
3588 recursion depth updates/checks. Required the creation of a static
3589 RuntimeError instance in case normalizing an exception put the
3590 recursion check value past its limit. Fixes crashers
3591 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003592
Georg Brandl3ee81df2008-05-17 18:14:43 +00003593- Patch #1031213: Decode source line in SyntaxErrors back to its

Georg Brandl3ee81df2008-05-17 18:14:43 +00003607 __*__ attributes. (Some already existed, e.g., __doc__ and
3608 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003609
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003610- Add -3 option to the interpreter to warn about features that are
3611 deprecated and will be changed/removed in Python 3.0.
3612
Georg Brandl2134e752007-05-21 20:34:16 +00003613- Patch #1686487: you can now pass any mapping after '**' in function
3614 calls.
3615
Collin Winter62903052007-05-18 23:11:24 +00003616- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003617 "except E as target:". This is to provide forwards compatibility
3618 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003619
Brett Cannon229cee22007-05-05 01:34:02 +00003620- Deprecate BaseException.message as per PEP 352.
3621
Georg Brandl3ee81df2008-05-17 18:14:43 +00003622- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003623 inherited from a builtin base.
3624
Vinay Sajip8549ce32007-05-06 17:53:37 +00003625- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003626 setting a plain string, ie don't expand to single letter identifiers.
3627
Raymond Hettinger13936692007-04-11 18:40:58 +00003628- Request #1191699: Slices can now be pickled.

3638
Guido van Rossum143b5642007-03-23 04:58:42 +00003639- Bug #1683368: The object.__init__() and object.__new__() methods are
3640 now stricter in rejecting excess arguments. The only time when
3641 either allows excess arguments is when it is not overridden and the
3642 other one is. For backwards compatibility, when both are
3643 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003644 warning later). Also, type.__init__() insists on the same signature
3645 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003647- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3648 object to complex using its __complex__() method before falling back
3649 to the __float__() method. Therefore, the functions in the cmath
3650 module now can operate on objects that define a __complex__()
3651 method.

3668
Georg Brandl7b9c5552007-03-12 14:30:05 +00003669- Bug #1678647: write a newline after printing an exception in any
3670 case, even when converting the value to a string failed.
3671
Georg Brandl871f1bc2007-03-12 13:17:36 +00003672- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003673 its argument, if it exists. If not, it will work like before. This
3674 allows customizing the output of dir() in the presence of a
3675 __getattr__().

3678 self-recursive reload() calls (as reported by bug #742342).

3684 parthensized forms. This means complex(repr(x)) now works instead of
3685 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003686
Georg Brandlaa2321b2007-03-07 00:40:28 +00003687- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003688 makes the filenames the warning module prints much more sensible
3689 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003690

Georg Brandl0fca97a2007-03-05 22:28:08 +00003702- Patch #1674228: when assigning a slice (old-style), check for the
3703 sq_ass_slice instead of the sq_slice slot.
3704
Georg Brandl3ee81df2008-05-17 18:14:43 +00003705- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003808 generator expressions (x for x, in ... ) works again. Fixing this

Georg Brandl3ee81df2008-05-17 18:14:43 +00004617- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4618 with RFC 3207 and forgets any knowledge obtained from the server not
4619 obtained from the TLS negotiation itself. Patch contributed by Bill
4620 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004621
Georg Brandl3ee81df2008-05-17 18:14:43 +00004622- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004623 that the SMTP.starttls() caller no longer needs to call ehlo()
4624 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004625 does not claim to support starttls. Adds the
4626 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4707 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4708 silently miscode subclasses of those types. Now, it raises a
4709 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004710

Georg Brandl3ee81df2008-05-17 18:14:43 +00004725 time so that opening a database previously created with the DB_DUP
4726 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4727 opens. Specifically: dictionary assignment to a DB object will
4728 replace all values for a given key when the database allows
4729 duplicate values. DB users should use DB.put(k, v) when they want
4730 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004731

4737 characters with ASCII value less than 32. Also, it correctly quotes
4738 dots only if they occur on a single line, as opposed to the previous
4739 behavior of quoting dots if they are the second character of any
4740 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004741

Georg Brandl3ee81df2008-05-17 18:14:43 +00005146- Removed the macfs module. It had been deprecated since Python 2.5.
5147 This lead to the deprecation of macostools.touched() as it relied
5148 solely on macfs and was a no-op under OS X.
