20 alpha 2, including: (1) a serious 'wrong output' bug that could
21 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
22 that occurred in debug builds when parsing certain long numeric
23 strings corresponding to subnormal values, and (3) a number of flaws
24 that could lead to incorrectly rounded results.

76Core and Builtins
77-----------------
78
Benjamin Petersonecdae192010-01-04 00:43:01 +000079- The __complex__ method is now looked up on the class of instances to make it
80 consistent with other special methods.
81
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000082- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
83 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
84
Mark Dickinson1b34d252010-01-01 17:27:30 +000085- Issue #5080: A number of functions and methods previously produced a
86 DeprecationWarning when passed a float argument where an integer was
87 expected. These functions and methods now raise TypeError instead.
88 The majority of the effects of this change are in the extension
89 modules, but some core functions and methods are affected: notably
90 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
91 methods.
92
Benjamin Peterson0f02d392009-12-30 19:34:10 +000093- Issue #7604: Deleting an unset slotted attribute did not raise an
94 AttributeError.

101
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000102- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
103 used to drop the time part of the result.
104
Mark Dickinson46572832009-12-27 14:55:57 +0000105- Issue #1811: improve accuracy and cross-platform consistency for
106 true division of integers: the result of a/b is now correctly
107 rounded for ints a and b (at least on IEEE 754 platforms), and in
108 particular does not depend on the internal representation of a long.
109
Ezio Melottif84caf42009-12-24 22:25:17 +0000110- Issue #6108: unicode(exception) and str(exception) should return the same
111 message when only __str__ (and not __unicode__) is overridden in the subclass.
112
Ronald Oussoren92919a62009-12-24 13:30:58 +0000113- Issue #6834: replace the implementation for the 'python' and 'pythonw'
114 executables on OSX.
115
116 These executables now work properly with the arch(1) command:
117 ``arch -ppc python`` will start a universal binary version of python
118 in PPC mode (unlike previous releases).
119
R. David Murray0a0a1a82009-12-14 16:28:26 +0000120- Issue #1680159: unicode coercion during an 'in' operation no longer masks
121 the underlying error when the coercion fails for the left hand operand.
122
Benjamin Peterson4895af42009-12-13 16:36:53 +0000123- Issue #7491: Metaclass's __cmp__ method was ignored.
124
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000125- Issue #7466: segmentation fault when the garbage collector is called

134 by Arfrever.
135
Antoine Pitrou80157252010-01-08 19:20:17 +0000136- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
137 renaming of `cPickle` to `pickle`. The warning was annoying since there's
138 no alternative to cPickle if you care about performance. Patch by Florent
139 Xicluna.

148 and make it implement the `io.BufferedIOBase` ABC to allow for further
149 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
150
151- Issue #3972: httplib.HTTPConnection now accepts an optional source_address

Senthil Kumaran7713acf2009-12-20 06:05:13 +0000170 Patch by Tatsuhiro Tsujikawa.
171
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000172- Issue #7349: Make methods of file objects in the io module accept None as an
173 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
174 the same as passing no argument.
175
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000176- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
177 like other file objects.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000247- Issue #7419: setlocale() could crash the interpreter on Windows when called
248 with invalid values.
249
Eric Smithc4ab8332009-11-29 17:40:57 +0000250- Issue #3382: 'F' formatting for float and complex now convert the
251 result to upper case. This only affects 'inf' and 'nan', since 'f'
252 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000253
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000254- Remove switch from "%f" formatting to "%g" formatting for floats
255 larger than 1e50 in absolute value.
256
Mark Dickinson18cfada2009-11-23 18:46:41 +0000257- Remove restrictions on precision when formatting floats. E.g.,
258 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
259 requested 120 significant digits instead.
260
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000261- Add Py3k warnings for parameter names in parenthesis.

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000264
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000265- Issue #7085: Fix crash when importing some extensions in a thread
266 on MacOSX 10.6.
267
Mark Dickinsonb678de82009-11-19 18:41:49 +0000268- Issue #7117: repr(x) for a float x returns a result based on the
269 shortest decimal string that's guaranteed to round back to x under
270 correct rounding (with round-half-to-even rounding mode).
271 Previously it gave a string based on rounding x to 17 decimal digits.
272 repr(x) for a complex number behaves similarly. On platforms where
273 the correctly-rounded strtod and dtoa code is not supported (see below),
274 repr is unchanged.
275
276- Issue #7117: On almost all platforms: float-to-string and
277 string-to-float conversions within Python are now correctly rounded.
278 Places these conversions occur include: str for floats and complex
279 numbers; the float and complex constructors; old-style and new-style
280 numeric formatting; serialization and deserialization of floats and
281 complex numbers using marshal, pickle and json; parsing of float and
282 imaginary literals in Python code; Decimal-to-float conversion.
283
284 The conversions use a Python-adapted version of David Gay's
285 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
286 functions. This code is supported on Windows, and on Unix-like
287 platforms using gcc, icc or suncc as the C compiler. There may be a
288 small number of platforms on which correct operation of this code
289 cannot be guaranteed, so the code is not used: notably, this applies
290 to platforms where the C double format is not IEEE 754 binary64, and
291 to platforms on x86 hardware where the x87 FPU is set to 64-bit
292 precision and Python's configure script is unable to determine how
293 to change the FPU precision. On these platforms conversions use the
294 platform strtod and dtoa, as before.
295
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000296- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000297 now uses the correctly-rounded string <-> float conversions
298 described above (when available), and so produces correctly rounded
299 results that will display nicely under the float repr. There are
300 two related small changes: (1) round now accepts any class with an
301 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000302 floats for the second argument), and (2) an excessively large second
303 integer argument (e.g., round(1.234, 10**100)) no longer raises an
304 exception.
305
Philip Jenveyfab8be22009-11-17 02:42:26 +0000306- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
307
Benjamin Petersone36199b2009-11-12 23:39:44 +0000308- Fix several issues with compile(). The input can now contain Windows and Mac

449 was locale aware; and (3) the interpretation of fromhex('-nan')
450 didn't match that of float('-nan').
451
Eric Smitha985a3a2009-05-05 18:26:08 +0000452- Issue #5920: For float.__format__, change the behavior with the
453 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
454 to be like 'g' but with at least one decimal point and with a
455 default precision of 12. Previously, the behavior the same but with
456 a default precision of 6. This more closely matches str(), and
457 reduces surprises when adding alignment flags to the empty
458 presentation type. This also affects the new complex.__format__ in
459 the same way.

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000602- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
603 an existing .py counterpart, override the co_filename attributes of all
604 code objects if the original filename is obsolete (which can happen if the
605 file has been renamed, moved, or if it is accessed through different paths).
606 Patch by Ziga Seilnacht and Jean-Paul Calderone.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000610- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
611 file with `str' filename on Windows.
612
Antoine Pitrouaa687902009-01-01 14:11:22 +0000613- Issue #3680: Reference cycles created through a dict, set or deque iterator
614 did not get collected.
615
Nick Coghlan180e4002008-12-30 01:18:48 +0000616- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types

618
Benjamin Peterson7af65562008-12-29 17:56:58 +0000619- Issue #4764: With io.open, IOError.filename is set when trying to open a

627
Skip Montanarof205c132008-12-23 03:30:15 +0000628- Added test case to ensure attempts to read from a file opened for writing

644 exceptions.
645
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000646- Issue #4445: Replace "sizeof(PyStringObject)" with
647 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
648 str instances. On a typical machine this saves 3 bytes of memory
649 (on average) per string allocation.
650
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000651- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
652 interpreter to abort ("Fatal Python error: Could not reset the stack!")
653 instead of throwing a MemoryError.
654
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000655- Issue #3689: The list reversed iterator now supports __length_hint__
656 instead of __len__. Behavior now matches other reversed iterators.
657
Benjamin Petersonc078f922008-11-21 22:27:24 +0000658- Issue #4367: Python would segfault during compiling when the unicodedata

660
Vinay Sajip213faca2008-12-03 23:22:58 +0000661- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000662 method on file objects with closefd=False. The file descriptor is still
663 kept open but the file object behaves like a closed file. The ``FileIO``
664 object also got a new readonly attribute ``closefd``.
665
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000666- Issue #4348: Some bytearray methods returned that didn't cause any change to
667 the bytearray, returned the same bytearray instead of a copy.
668
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000669- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
670

677
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000678- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
679 method does not return iterators for the 4th and 5th items.
680
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000681- Issue #4209: Enabling unicode_literals and the print_function in the same
682 __future__ import didn't work.
683
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000684- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000685 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000686
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000687- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
688 returned a path longer than MAX_PATH. (But It's doubtful this code path is
689 really executed because I cannot move to such directory on win2k)
690
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000691- Issue #4069: When set.remove(element) is used with a set element, the element
692 is temporarily replaced with an equivalent frozenset. But the eventual
693 KeyError would always report the empty frozenset([]) as the missing key. Now
694 it correctly refers to the initial element.
695
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000696- Issue #4509: Various issues surrounding resize of bytearray objects to

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000711- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
712 returned them on 64bit platforms.
713
Walter Dörwalded960ac2009-05-03 22:36:33 +0000714- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
715 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
716 step. This avoids problems with counting UTF-8 bytes that ignores the effect
717 of using the replace error handler in PyUnicode_DecodeUTF8().
718
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000719- Issue #3739: The unicode-internal encoder now reports the number of characters
720 consumed like any other encoder (instead of the number of bytes).
721
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000722- Issue #2422: When compiled with the ``--with-valgrind`` option, the
723 pymalloc allocator will be automatically disabled when running under
724 Valgrind. This gives improved memory leak detection when running
725 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +0000794- Issue #6816: runpy now provides a run_path function that allows Python code

1983 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1984 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1985 skip the tests if DISPLAY is defined but can't be used.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002105- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2106
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002107- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2108 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2109 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2110 ``printf`` function, whereas PyString_FromFormat has an independent
2111 implementation and uses "%zd" on all platforms for size_t values.
2112 This makes a difference on win64, where ``printf`` needs "%Id" to display
2113 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002115- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2119 object; previously an int would be returned for small values. the __long__
2120 method is allowed to return either an int or a long, but the behaviour of
2121 float objects should not change to respect backward compatibility.
2122
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002123- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002129 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002130 was correctly parsed but parsing of subsequent arguments failed.
2131
Vinay Sajip35e3b032008-09-01 14:33:59 +00002132- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002133 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2134 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2135 when given a tuple of classes as second argument, were looking up
2136 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2137 type object.
2138
Neal Norwitz18aa3882008-08-24 05:04:52 +00002139- Fix crashes on memory allocation failure found with failmalloc.

Martin v. Löwis67543a92008-09-08 12:02:45 +00002270- Allow passing the MSI file name to merge.py.
2271
Vinay Sajip844f7412008-09-09 13:42:08 +00002272- Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002273 with GNU build target guidelines.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002276What's New in Python 2.6 beta 3?
2277================================
2278
Barry Warsaw07a4a382008-08-21 01:15:08 +00002279*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002280
2281Core and Builtins
2282-----------------
2283
Guido van Rossumf8402962008-08-20 15:01:50 +00002284- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2285 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2286 extensions do not automatically benefit from the class attribute
2287 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2288 to their tp_flags field if they care. This is a backwards
2289 compatibility feature; in 3.0, all types will use the cache by
2290 default.
2291
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002292- Keyword arguments can now follow starred arguments. (``f(a, *args,
2293 keyword=23)`` is now valid syntax.)
2294
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002295- ctypes function pointers that are COM methods have a boolean True
2296 value again.
2297
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002298- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2299 by denying s# to parse objects that have a releasebuffer procedure,
2300 and introducing s*.
2301
Georg Brandl1e13ea92008-08-11 09:07:59 +00002302- Issue #3537: Fix an assertion failure when an empty but presized dict
2303 object was stored in the freelist.
2304
Mark Dickinsonb6467572008-08-04 21:30:09 +00002305- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2306 ValueError consistently across platforms.
2307
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002308- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2309 (64bit Unix, for example), unichr() would truncate its argument and return
2310 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2311
Neal Norwitze7d8be82008-07-31 17:17:14 +00002312- Apply security patches from Apple.
2313
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002314- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2315 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2316
Antoine Pitrou92f82162008-07-25 22:22:08 +00002317- Issue #1819: function calls with several named parameters are now on
2318 average 35% faster (as measured by pybench).
2319
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002320- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2321 the python debugger steps into a class statement: the free variables (local
2322 variables defined in an outer scope) would be deleted from the outer scope.
2323
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002324- Issue #2620: Overflow checking when allocating or reallocating memory
2325 was not always being done properly in some python types and extension
2326 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2327 all been updated to perform better checks and places in the code that
2328 would previously leak memory on the error path when such an allocation
2329 failed have been fixed.
2330
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002331Library
2332-------
2333
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002334- Issue #3612: Added some missing basic types in ctypes.wintypes.
2335
Benjamin Petersone977ad42008-08-20 01:42:01 +00002336- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2337 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2338
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002339- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2340 version reported by these tools does not necessarily follow the python
2341 version numbering scheme, so the module is less strict when parsing it.
2342
Nick Coghlanf70385a2008-08-18 12:42:46 +00002343- Issue #2235: Added Py3k warnings for types which will become unhashable
2344 under the stricter __hash__ inheritance rules in 3.0. Several types
2345 which did not meet the rules for hash invariants and were already
2346 unhashable in 3.0 have now been explicitly flagged as unhashable in
2347 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2348 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2349
Brett Cannon88f801d2008-08-18 00:46:22 +00002350- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2351 imported into the module but exposed as part of the module's API.
2352
Brett Cannon7b96f072008-08-18 00:41:11 +00002353- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2354
Brett Cannon46225e72008-08-18 00:36:52 +00002355- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2356
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002357- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2358
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002359- Issue #3575: Incremental decoder's decode function now takes bytearray
2360 by using 's*' instead of 't#'.
2361
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002362- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002363 fails unicode conversion on 2nd parameter. (windows only)
2364
Facundo Batista94f243a2008-08-17 03:38:39 +00002365- Issue 2464. urllib2 now supports a malformation in the URL received
2366 in a redirect.
2367
Brett Cannonabe423e2008-08-16 21:47:07 +00002368- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002369 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002370
Facundo Batistaeb90b782008-08-16 14:44:07 +00002371- Issue #2776: fixed small issue when handling an URL with double slash
2372 after a 302 response in the case of not going through a proxy.
2373
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002374- Issue #2676: in the email package, content-type parsing was hanging on
2375 pathological input because of quadratic or exponential behaviour of a
2376 regular expression.
2377
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002378- Issue #3476: binary buffered reading through the new "io" library is now
2379 thread-safe.
2380
Brett Cannonbf3157b2008-08-14 05:00:03 +00002381- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2382 since mimetools itself is deprecated. Because modules are cached, all
2383 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2384
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002385- Issue #3134: shutil referenced undefined WindowsError symbol.
2386
Robert Schuppenies14646332008-08-10 11:01:53 +00002387- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2388 menu entries were not deleted.
2389
Brett Cannon83e81842008-08-09 23:30:55 +00002390- Copied the implementation of reduce() to _functools.reduce() to have a
2391 version that did not raise a DeprecationWarning under -3.
2392
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002393- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2394 a MemoryError rather than silently stop the iteration.
2395
Guido van Rossum59ce9012008-08-09 14:55:34 +00002396- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2397 to _sre.compile() will now be rejected. This should not affect anybody
2398 since the re.compile() function never generates invalid re-bytecode.
2399
Skip Montanaroa032bf42008-08-08 22:52:51 +00002400- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2401 upon first access it can be automatically initialized from the csv file if
2402 it wasn't initialized during instantiation.
2403
Brett Cannon3aa2a492008-08-06 22:28:09 +00002404- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2405 the reload() built-in has been removed.
2406
Brett Cannon7e30b672008-08-04 21:52:25 +00002407- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002408 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2411 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2412 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2413 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002414
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002415- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2416 raised an AttributeError.
2417
Benjamin Peterson01a24322008-07-28 23:35:27 +00002418- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002419 asking for a specific length. This problem only affected files opened
2420 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002421
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002422- Issue #3449: Update decimal module to use most recent specification
2423 (v. 1.68) and tests (v. 2.58) from IBM.
2424
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002425- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2433
2434- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2435 invalid arguments.
2436
2437- Issue #3302: Fix several crashes when calling locale's gettext functions
2438 with None arguments.
2439
2440- Issue #3389: Allow resolving dotted names for handlers in logging
2441 configuration files.
2442
2443- Deprecate the sunaudio module for removal in Python 3.0.
2444
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002445- Issue #3394: zipfile.writestr sets external attributes when passed a
2446 file name rather than a ZipInfo instance, so files are extracted with
2447 mode 0600 rather than 000 under Unix.
2448
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002449- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2450 argument in python 2.5, this broke code that subclassed Popen to include its
2451 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2459-------------
2460
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002461- Issue #2235: the C API function PyObject_HashNotImplemented and its
2462 interaction with the tp_hash slot (added in 2.6b2) are now documented
2463
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002464- Issue #643841: The language reference now provides more detailed
2465 coverage of the lookup process for special methods. The disclaimers
2466 regarding lack of coverage of new-style classes have also been
2467 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002470What's New in Python 2.6 beta 2?
2471================================
2472
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002473*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002475Core and Builtins
2476-----------------
2477
Georg Brandl3e483f62008-07-16 22:57:41 +00002478- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2479 its methods now allow for items objects that can be converted to
2480 an integer using operator.index().
2481
Mark Dickinson64b7e502008-07-16 09:40:03 +00002482- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2483 produced a ValueError instead of giving the correct float.
2484
Eric Smitha5fa5a22008-07-16 00:11:49 +00002485- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2486 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2487
Mark Dickinson7103aa42008-07-15 19:08:33 +00002488- Issue #3008: the float type has a new instance method 'float.hex'
2489 and a new class method 'float.fromhex' to convert floating-point
2490 numbers to and from hexadecimal strings, respectively.
2491
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002492- Issue #2235: __hash__ is once again inherited by default. To allow
2493 collections.Hashable to remain meaningful in the presence of the
2494 default hash implementation (object.__hash__), it is now possible
2495 to explicit block inheritance of hash by setting __hash__=None at
2496 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2497 level.
2498
Nick Coghlanb028f502008-07-13 14:52:36 +00002499- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2500 the parent module cannot be found while performing an absolute import.
2501 This means that an incorrectly defined __package__ attribute will
2502 now only prevent relative imports in that module rather than causing
2503 all imports from that module to fail.
2504
Nick Coghlan14ff9942008-07-08 14:21:42 +00002505- Issue #2517: Allow unicode messages in Exceptions again by correctly
2506 bypassing the instance dictionary when looking up __unicode__ on
2507 new-style classes.
2508
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002509- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2510 set to a custom object whose write() method happens to install
2511 another file in sys.stdout.
2512
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002513- Issue #3088: Corrected a race condition in classes derived from
2514 threading.local: the first member set by a thread could be saved in
2515 another thread's dictionary.
2516
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002517- Issue #3004: Minor change to slice.indices(): the start and stop
2518 arguments are now treated identically, making the behaviour easier
2519 to describe and understand. For example, slice(None, -10,
2520 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2521 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2522 10, -1).
2523
Georg Brandl278fc502008-07-19 12:46:12 +00002524- Issue #3219: Calling a function with repeated keyword arguments,
2525 f(a=2, a=23), would not cause a syntax error. This was a regression
2526 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002527
Georg Brandl278fc502008-07-19 12:46:12 +00002528- Issue #2862: Make int and float freelist management consistent with
2529 other freelists. Changes their CompactFreeList apis into
2530 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002531

2534
Thomas Heller57adf222008-08-14 19:10:48 +00002535- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2536 api functions without holding the GIL, which could lead to a fatal
2537 error when they failed.
2538
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002539- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2548 ForkingPickler.register() to resolve conflict with ctypes.
2549
Vinay Sajip51e65192008-07-18 09:01:10 +00002550- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller2bad6572008-07-15 17:19:50 +00002555- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2556 incomplete structure was created.
2557
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002558- Issue #3339: dummy_thread.acquire() should not return None.

2975 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002976 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002977
2978 This is controlled by the configure argument ``--with-universal-archs``:
2979
2980 - ``--with-universal-archs=all``: install 4-way universal
2981
2982 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2983
2984 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2985
2986 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003038- Issue #1631171: Re-implement the 'warnings' module in C (the
3039 original Python code has been kept as backup). This will allow for
3040 using the 'warning's machinery in such places as the parser where
3041 use of pure Python code is not possible. Both the ``showarning()``
3042 and ``formatwarning()`` gain an optional 'line' argument which is
3043 not called by default for backwards-compatibility reasons. Setting
3044 ``warnings.showwarning()`` to an implementation that lacks support
3045 for the ``line`` argument will raise a DeprecationWarning.

3069
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003070- The getpass module has been improved on Unix. It now uses /dev/tty
3071 by default and uses stderr instead of stdout. A GetPassWarning is
3072 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003087- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003088 extension modules between 32 and 64 bit platforms. See the distutls

3112 test_support.bind_port() has been fixed such that it will always
3113 return a unique port -- which wasn't always the case with the
3114 previous implementation, especially if socket options had been set
3115 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3116 new implementation of bind_port() will actually raise an exception
3117 if it is passed an AF_INET/SOCK_STREAM socket with either the
3118 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3119 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3120 the socket it's been passed. This currently only applies to
3121 Windows. This option prevents any other sockets from binding to the
3122 host/port we've bound to, thus removing the possibility of the
3123 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3124 when a second SOCK_STREAM socket binds and accepts to a host/port
3125 that's already been bound by another socket. The optional preferred
3126 port parameter to bind_port() has been removed. Under no
3127 circumstances should tests be hard coding ports!
3128
3129 test_support.find_unused_port() has also been introduced, which will
3130 pass a temporary socket object to bind_port() in order to obtain an
3131 unused port. The temporary socket object is then closed and
3132 deleted, and the port is returned. This method should only be used
3133 for obtaining an unused port in order to pass to an external program
3134 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3135 a parameter to a server-oriented class that doesn't give you direct
3136 access to the underlying socket used.
3137
3138 Finally, test_support.HOST has been introduced, which should be used
3139 for the host argument of any relevant socket calls (i.e. bind and
3140 connect).

3142 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003143 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003144 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3145 test_asynchat and test_socket_ssl.
3146
Georg Brandl3ee81df2008-05-17 18:14:43 +00003147 It is now possible for multiple instances of the regression test
3148 suite to run in parallel without issue.

3414Core and builtins
3415-----------------
3416
Fred Drakea8ee94b2008-03-01 02:45:07 +00003417- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003418 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003419
Georg Brandlad61bc82008-02-23 15:11:18 +00003420- Issue #2067: file.__exit__() now calls subclasses' close() method.
3421
3422- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003423
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003424- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003425 issue 215555 for a discussion.
3426
Eric Smitha73fbe72008-02-23 03:09:44 +00003427- Added the future_builtins module, which contains hex() and oct().
3428 These are the PEP 3127 version of these functions, designed to be
3429 compatible with the hex() and oct() builtins from Python 3.0. They
3430 differ slightly in their output formats from the existing, unchanged
3431 Python 2.6 builtins. The expected usage of the future_builtins
3432 module is:
3433 from future_builtins import hex, oct
3434
Eric Smith7ef40bf2008-02-20 23:34:22 +00003435- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3436 exponents for exponents with absolute value < 100. Follows C99
3437 standard. This is a change on Windows, which would use 3 digits.
3438 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3439 so that any alterations it does to the resulting string will be
3440 available in stringlib/formatter.h (for float.__format__).
3441
Eric Smith5a3c1352008-02-19 13:21:56 +00003442- Implemented PEP 3101, Advanced String Formatting. This adds a new
3443 builtin format(); a format() method for str and unicode; a
3444 __format__() method to object, str, unicode, int, long, float, and
3445 datetime; the class string.Formatter; and the C API
3446 PyObject_Format().
3447
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448- Fixed several potential crashes, all caused by specially crafted
3449 __del__ methods exploiting objects in temporarily inconsistent
3450 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003451
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003452- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003453 prevent a possible crash: an Abstract Base Class would try to access
3454 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003455
Georg Brandl3ee81df2008-05-17 18:14:43 +00003456- Fixed repr() and str() of complex numbers with infinity or nan as
3457 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003458
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459- Clear all free lists during a gc.collect() of the highest generation
3460 in order to allow pymalloc to free more arenas. Python may give back
3461 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003462
Georg Brandl3ee81df2008-05-17 18:14:43 +00003463- Issue #2045: Fix an infinite recursion triggered when printing a
3464 subclass of collections.defaultdict, if its default_factory is set
3465 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003466
Christian Heimesf75dbef2008-02-08 00:11:31 +00003467- Fixed a minor memory leak in dictobject.c. The content of the free
3468 list was not freed on interpreter shutdown.
3469
Georg Brandl3ee81df2008-05-17 18:14:43 +00003470- Limit free list of method and builtin function objects to 256
3471 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003472
Georg Brandl3ee81df2008-05-17 18:14:43 +00003473- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3474 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003475 to compact the internal free lists of pre-allocted ints and floats.
3476
Georg Brandl3ee81df2008-05-17 18:14:43 +00003477- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3478 calls. Python expected the return type int but the fork familie
3479 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003480
Georg Brandl3ee81df2008-05-17 18:14:43 +00003481- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3482 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003483
Georg Brandl3ee81df2008-05-17 18:14:43 +00003484- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3485 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003486
Georg Brandl3ee81df2008-05-17 18:14:43 +00003487- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3488 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003489
Georg Brandl3ee81df2008-05-17 18:14:43 +00003490- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3491 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003492
Georg Brandl3ee81df2008-05-17 18:14:43 +00003493- Patch #1473257: generator objects gain a gi_code attribute. This is
3494 the same object as the func_code attribute of the function that
3495 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003496
Georg Brandl3ee81df2008-05-17 18:14:43 +00003497- Issue #1920: "while 0" statements were completely removed by the
3498 compiler, even in the presence of an "else" clause, which is
3499 supposed to be run when the condition is false. Now the compiler
3500 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003501
Guido van Rossumeead05f2008-01-24 18:21:02 +00003502- A few crashers fixed: weakref_in_del.py (issue #1377858);
3503 loosing_dict_ref.py (issue #1303614, test67.py);
3504 borrowed_ref_[34].py (not in tracker).
3505
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003506- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003507 suppressed while an extension is loaded by calling SetErrorMode in
3508 dynload_win.c. The error is still reported properly.
3509
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003511 several extension methods and modules do not work without unicode
3512 support.
3513
Georg Brandl26543b12008-01-21 18:36:51 +00003514- Issue #1882: when compiling code from a string, encoding cookies in the
3515 second line of code were not always recognized correctly.
3516
Georg Brandl14404b62008-01-19 19:27:05 +00003517- Issue #1679: "0x" was taken as a valid integer literal.
3518
Georg Brandl6caad7d2008-01-26 14:19:22 +00003519- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003520 added.
3521
Christian Heimesc94e2b52008-01-14 04:13:37 +00003522- sys.float_info / PyFloat_GetInfo: The floating point information
3523 object was converted from a dict to a specialized structseq object.
3524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Patch #1816: Added sys.flags structseq. It exposes the status of
3526 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003527
Georg Brandl3ee81df2008-05-17 18:14:43 +00003528- Objects/structseq.c: Implemented new structseq representation. The
3529 patch makes structseqs (e.g. the return value of os.stat) more
3530 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003531
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- Patch #1700288: added a type attribute cache that caches method
3533 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003534
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003535- Bug #1776: __import__() no longer accepts filenames on any platform.
3536 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003537
Georg Brandlaed6c662008-01-07 17:25:53 +00003538- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3539
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3541 envvar and sys.dont_write_bytecode attribute. All these can be set
3542 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003543
Georg Brandl3ee81df2008-05-17 18:14:43 +00003544- Improve some exception messages when Windows fails to load an
3545 extension module. Now we get for example '%1 is not a valid Win32
3546 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003547
Georg Brandl3ee81df2008-05-17 18:14:43 +00003548- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3551 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003552
Christian Heimes0a8143f2007-12-18 23:22:54 +00003553- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003554 and INF. float("nan"), float("inf") and float("-inf") now work on
3555 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003556
Georg Brandl3ee81df2008-05-17 18:14:43 +00003557- Compiler now generates simpler and faster code for dictionary
3558 literals. The oparg for BUILD_MAP now indicates an estimated
3559 dictionary size. There is a new opcode, STORE_MAP, for adding
3560 entries to the dictionary.

3575 __package__ attribute.
3576
Georg Brandl3ee81df2008-05-17 18:14:43 +00003577- Issue #1402: Fix a crash on exit, when another thread is still
3578 running, and if the deallocation of its frames somehow calls the
3579 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003580

3590 file can now be directly executed by passing their name to the
3591 interpreter. The directory/zipfile is automatically inserted as the
3592 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003593
Georg Brandl3ee81df2008-05-17 18:14:43 +00003594- Issue #1265: Fix a problem with sys.settrace, if the tracing
3595 function uses a generator expression when at the same time the
3596 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003597
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003598- sets and frozensets now have an isdisjoint() method.
3599
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003600- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00003602- Fix warnings found by the new version of the Coverity checker.
3603
Georg Brandl3ee81df2008-05-17 18:14:43 +00003604- The enumerate() builtin function is no longer bounded to sequences
3605 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3606 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003607
Georg Brandl3ee81df2008-05-17 18:14:43 +00003608- Issue #1686386: Tuple's tp_repr did not take into account the
3609 possibility of having a self-referential tuple, which is possible
3610 from C code. Nor did object's tp_str consider that a type's tp_str
3611 could do something that could lead to an inifinite recursion.
3612 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3613 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003614
Georg Brandl3ee81df2008-05-17 18:14:43 +00003615- Issue #1164: It was possible to trigger deadlock when using the
3616 'print' statement to write to a file since the GIL was not released
3617 as needed. Now PyObject_Print() does the right thing along with
3618 various tp_print implementations of the built-in types and those in

Georg Brandl3ee81df2008-05-17 18:14:43 +00003621- Issue #1147: Exceptions were directly allowing string exceptions in
3622 their throw() method even though string exceptions no longer
3623 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003624
Georg Brandl3ee81df2008-05-17 18:14:43 +00003625- Issue #1096: Prevent a segfault from getting the repr of a very
3626 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003627
Brett Cannon1e534b52007-09-07 04:18:30 +00003628- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003629 PyObject_Call() never calling back out to Python code to trigger
3630 recursion depth updates/checks. Required the creation of a static
3631 RuntimeError instance in case normalizing an exception put the
3632 recursion check value past its limit. Fixes crashers
3633 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003648- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003649 __*__ attributes. (Some already existed, e.g., __doc__ and
3650 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003651
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003652- Add -3 option to the interpreter to warn about features that are

3656 calls.
3657
Collin Winter62903052007-05-18 23:11:24 +00003658- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003659 "except E as target:". This is to provide forwards compatibility
3660 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003661
Brett Cannon229cee22007-05-05 01:34:02 +00003662- Deprecate BaseException.message as per PEP 352.
3663
Georg Brandl3ee81df2008-05-17 18:14:43 +00003664- Issue #1303614: don't expose object's __dict__ when the dict is

3666
Vinay Sajip8549ce32007-05-06 17:53:37 +00003667- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003668 setting a plain string, ie don't expand to single letter identifiers.
3669
Raymond Hettinger13936692007-04-11 18:40:58 +00003670- Request #1191699: Slices can now be pickled.
3671
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003672- Request #1193128: str.translate() now allows a None argument for
3673 translations that only remove characters without re-mapping the
3674 remaining characters.
3675
Georg Brandl5cb76c12007-03-21 09:00:39 +00003676- Patch #1682205: a TypeError while unpacking an iterable is no longer

3680
Guido van Rossum143b5642007-03-23 04:58:42 +00003681- Bug #1683368: The object.__init__() and object.__new__() methods are
3682 now stricter in rejecting excess arguments. The only time when
3683 either allows excess arguments is when it is not overridden and the
3684 other one is. For backwards compatibility, when both are
3685 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003686 warning later). Also, type.__init__() insists on the same signature
3687 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003688
Georg Brandl3ee81df2008-05-17 18:14:43 +00003689- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3690 object to complex using its __complex__() method before falling back
3691 to the __float__() method. Therefore, the functions in the cmath
3692 module now can operate on objects that define a __complex__()
3693 method.

3696 __slots__. The old and the new class are still required to have the
3697 same slot names.

3710
Georg Brandl7b9c5552007-03-12 14:30:05 +00003711- Bug #1678647: write a newline after printing an exception in any
3712 case, even when converting the value to a string failed.
3713
Georg Brandl871f1bc2007-03-12 13:17:36 +00003714- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003715 its argument, if it exists. If not, it will work like before. This
3716 allows customizing the output of dir() in the presence of a
3717 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003718
Collin Winter276887b2007-03-12 16:11:39 +00003719- Patch #922167: Python no longer segfaults when faced with infinitely
3720 self-recursive reload() calls (as reported by bug #742342).

3726 parthensized forms. This means complex(repr(x)) now works instead of
3727 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003728
Georg Brandlaa2321b2007-03-07 00:40:28 +00003729- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003730 makes the filenames the warning module prints much more sensible
3731 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003732

Georg Brandl0fca97a2007-03-05 22:28:08 +00003744- Patch #1674228: when assigning a slice (old-style), check for the
3745 sq_ass_slice instead of the sq_slice slot.
3746
Georg Brandl3ee81df2008-05-17 18:14:43 +00003747- When printing an unraisable error, don't print exceptions. before
3748 the name. This duplicates the behavior whening normally printing
3749 exceptions.

4358 Python would crash instead of raising an error.
4359
Thomas Hellerc2f77252007-03-09 19:21:28 +00004360- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
4361 returned string up to the first NUL character.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004373- unittest now verifies more of its assumptions. In particular,
4374 TestCase and TestSuite subclasses (not instances) are no longer
4375 accepted in TestSuite.addTest(). This should cause no
4376 incompatibility since it never made sense with ordinary subclasses
4377 -- the failure just occurred later, with a more cumbersome
4378 exception.

4661 obtained from the TLS negotiation itself. Patch contributed by Bill
4662 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004663
Georg Brandl3ee81df2008-05-17 18:14:43 +00004664- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004665 that the SMTP.starttls() caller no longer needs to call ehlo()
4666 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004667 does not claim to support starttls. Adds the
4668 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4749 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4750 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004767 time so that opening a database previously created with the DB_DUP
4768 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4769 opens. Specifically: dictionary assignment to a DB object will
4770 replace all values for a given key when the database allows
4771 duplicate values. DB users should use DB.put(k, v) when they want
4772 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004773

4779 characters with ASCII value less than 32. Also, it correctly quotes
4780 dots only if they occur on a single line, as opposed to the previous
4781 behavior of quoting dots if they are the second character of any
4782 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004783

5105-----
5106
Georg Brandl3ee81df2008-05-17 18:14:43 +00005107- Unified naming convention for free lists and their limits. All free
5108 lists in Object/ are named ``free_list``, the counter ``numfree``
5109 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5110 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005111
Georg Brandl3ee81df2008-05-17 18:14:43 +00005112- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5113 to ``PyTuple_SetItem``, it can be used to populate a brand new
5114 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005115
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005116- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005118- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5119 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5120 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005121
5122- Patch #1720595: add T_BOOL to the range of structmember types.
5123
5124- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5125 ``PyFloat_GetInfo()`` to the float API.
5126
Georg Brandl3ee81df2008-05-17 18:14:43 +00005127- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5128 of w# format code incorrectly truncated the length to an int, even
5129 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5130 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005131
Georg Brandl3ee81df2008-05-17 18:14:43 +00005132- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5133 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005134
Georg Brandl3ee81df2008-05-17 18:14:43 +00005135- PEP 3123: Provide forward compatibility with Python 3.0, while
5136 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5137 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005138
Georg Brandl3ee81df2008-05-17 18:14:43 +00005139- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5140 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005141
5142- Patch #1733960: Allow T_LONGLONG to accept ints.
5143
5144- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5145

5149
5150- Fix some leftovers from the conversion from int to Py_ssize_t
5151 (relevant to strings and sequences of more than 2**31 items).
5152
5153- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5154 outside of pystate.c and should not be necessary.
5155
Georg Brandl3ee81df2008-05-17 18:14:43 +00005156- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5157 absolute imports. In earlier versions they might have used relative
5158 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005159
Georg Brandl3ee81df2008-05-17 18:14:43 +00005160- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5161 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005162
Georg Brandl3ee81df2008-05-17 18:14:43 +00005163- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5164 macro so it can be used as an expression.

5169
Georg Brandl3ee81df2008-05-17 18:14:43 +00005170- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5171 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5172 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5173 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005174
Georg Brandl3ee81df2008-05-17 18:14:43 +00005175- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005188- Removed the macfs module. It had been deprecated since Python 2.5.
5189 This lead to the deprecation of macostools.touched() as it relied
5190 solely on macfs and was a no-op under OS X.
