Antoine Pitroue80a6a42010-01-17 12:26:20 +000015- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
16 could crash in many places because of the PyByteArray_AS_STRING() macro
17 returning NULL. The macro now returns a statically allocated empty
18 string instead.
19
Antoine Pitrou64672132010-01-13 07:55:48 +000020- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
21 methods of bytes, bytearray and unicode objects by using a common
22 implementation based on stringlib's fast search. Patch by Florent Xicluna.

Mark Dickinson476279f2010-01-16 10:44:00 +000024- Issue #7632: Fix various str -> float conversion bugs present in 2.7
25 alpha 2, including: (1) a serious 'wrong output' bug that could
26 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
27 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000028 strings corresponding to subnormal values, (3) a memory leak for
29 some values large enough to cause overflow, and (4) a number of
30 flaws that could lead to incorrectly rounded results.

48 the release file is empty.
49
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +000050- Issue #7748: Since unicode values are supported for some metadata options

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000108What's New in Python 2.7 alpha 2?
109=================================

113Core and Builtins
114-----------------
115
Benjamin Petersonecdae192010-01-04 00:43:01 +0000116- The __complex__ method is now looked up on the class of instances to make it
117 consistent with other special methods.
118
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000119- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
120 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
121
Mark Dickinson1b34d252010-01-01 17:27:30 +0000122- Issue #5080: A number of functions and methods previously produced a
123 DeprecationWarning when passed a float argument where an integer was
124 expected. These functions and methods now raise TypeError instead.
125 The majority of the effects of this change are in the extension
126 modules, but some core functions and methods are affected: notably
127 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
128 methods.
129
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000130- Issue #7604: Deleting an unset slotted attribute did not raise an

138
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000139- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
140 used to drop the time part of the result.
141
Mark Dickinson46572832009-12-27 14:55:57 +0000142- Issue #1811: improve accuracy and cross-platform consistency for
143 true division of integers: the result of a/b is now correctly
144 rounded for ints a and b (at least on IEEE 754 platforms), and in
145 particular does not depend on the internal representation of a long.
146
Ezio Melottif84caf42009-12-24 22:25:17 +0000147- Issue #6108: unicode(exception) and str(exception) should return the same
148 message when only __str__ (and not __unicode__) is overridden in the subclass.
149
Ronald Oussoren92919a62009-12-24 13:30:58 +0000150- Issue #6834: replace the implementation for the 'python' and 'pythonw'
151 executables on OSX.
152
153 These executables now work properly with the arch(1) command:
154 ``arch -ppc python`` will start a universal binary version of python
155 in PPC mode (unlike previous releases).
156
R. David Murray0a0a1a82009-12-14 16:28:26 +0000157- Issue #1680159: unicode coercion during an 'in' operation no longer masks
158 the underlying error when the coercion fails for the left hand operand.
159
Benjamin Peterson4895af42009-12-13 16:36:53 +0000160- Issue #7491: Metaclass's __cmp__ method was ignored.
161
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000162- Issue #7466: segmentation fault when the garbage collector is called

171 by Arfrever.
172
Antoine Pitrou80157252010-01-08 19:20:17 +0000173- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
174 renaming of `cPickle` to `pickle`. The warning was annoying since there's
175 no alternative to cPickle if you care about performance. Patch by Florent
176 Xicluna.
177
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000178- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

186 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
187
188- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +0000189 parameter to allow specifying where your connections come from.

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000209- Issue #7349: Make methods of file objects in the io module accept None as an
210 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
211 the same as passing no argument.
212
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000213- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
214 like other file objects.
215

237 attempt to pass a float resulted in a DeprecationWarning; now it
238 gives a TypeError. For the 'L' format code (which previously had no
239 warning) there is now a DeprecationWarning.

306 shortest decimal string that's guaranteed to round back to x under
307 correct rounding (with round-half-to-even rounding mode).
308 Previously it gave a string based on rounding x to 17 decimal digits.
309 repr(x) for a complex number behaves similarly. On platforms where
310 the correctly-rounded strtod and dtoa code is not supported (see below),
311 repr is unchanged.
312
313- Issue #7117: On almost all platforms: float-to-string and
314 string-to-float conversions within Python are now correctly rounded.
315 Places these conversions occur include: str for floats and complex
316 numbers; the float and complex constructors; old-style and new-style
317 numeric formatting; serialization and deserialization of floats and
318 complex numbers using marshal, pickle and json; parsing of float and
319 imaginary literals in Python code; Decimal-to-float conversion.
320
321 The conversions use a Python-adapted version of David Gay's
322 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
323 functions. This code is supported on Windows, and on Unix-like
324 platforms using gcc, icc or suncc as the C compiler. There may be a
325 small number of platforms on which correct operation of this code
326 cannot be guaranteed, so the code is not used: notably, this applies
327 to platforms where the C double format is not IEEE 754 binary64, and
328 to platforms on x86 hardware where the x87 FPU is set to 64-bit
329 precision and Python's configure script is unable to determine how
330 to change the FPU precision. On these platforms conversions use the
331 platform strtod and dtoa, as before.

Mark Dickinsonbd15a062009-11-18 19:33:35 +0000333- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000334 now uses the correctly-rounded string <-> float conversions
335 described above (when available), and so produces correctly rounded
336 results that will display nicely under the float repr. There are
337 two related small changes: (1) round now accepts any class with an
338 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000339 floats for the second argument), and (2) an excessively large second
340 integer argument (e.g., round(1.234, 10**100)) no longer raises an
341 exception.

Raymond Hettingerb5163702009-02-02 21:50:13 +0000609 were suppressing all exceptions. These include list(), filter(), map(),
610 zip(), and bytearray().
611
Benjamin Peterson596d3062009-01-19 15:42:23 +0000612- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Antoine Pitrouc2f02212009-01-13 23:13:52 +0000620- Issue #4935: The overflow checking code in the expandtabs() method common
621 to str, bytes and bytearray could be optimized away by the compiler, letting
622 the interpreter segfault instead of raising an error.
623
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000624- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000631- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
632 collecting the oldest generation) so that allocating lots of objects without
633 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000634 Martin von Löwis at

638
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000639- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
640 an existing .py counterpart, override the co_filename attributes of all
641 code objects if the original filename is obsolete (which can happen if the
642 file has been renamed, moved, or if it is accessed through different paths).
643 Patch by Ziga Seilnacht and Jean-Paul Calderone.

649
Antoine Pitrouaa687902009-01-01 14:11:22 +0000650- Issue #3680: Reference cycles created through a dict, set or deque iterator

679
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000680- Issue #4597: Fixed several opcodes that weren't always propagating
681 exceptions.
682
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000683- Issue #4445: Replace "sizeof(PyStringObject)" with
684 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
685 str instances. On a typical machine this saves 3 bytes of memory
686 (on average) per string allocation.
687
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000688- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
689 interpreter to abort ("Fatal Python error: Could not reset the stack!")
690 instead of throwing a MemoryError.
691
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000692- Issue #3689: The list reversed iterator now supports __length_hint__
693 instead of __len__. Behavior now matches other reversed iterators.
694
Benjamin Petersonc078f922008-11-21 22:27:24 +0000695- Issue #4367: Python would segfault during compiling when the unicodedata

697
Vinay Sajip213faca2008-12-03 23:22:58 +0000698- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000699 method on file objects with closefd=False. The file descriptor is still
700 kept open but the file object behaves like a closed file. The ``FileIO``
701 object also got a new readonly attribute ``closefd``.
702
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000703- Issue #4348: Some bytearray methods returned that didn't cause any change to
704 the bytearray, returned the same bytearray instead of a copy.
705
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000706- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
707

711
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000712- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

714
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000715- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
716 method does not return iterators for the 4th and 5th items.
717
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000718- Issue #4209: Enabling unicode_literals and the print_function in the same
719 __future__ import didn't work.
720
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000721- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000722 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000724- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
725 returned a path longer than MAX_PATH. (But It's doubtful this code path is
726 really executed because I cannot move to such directory on win2k)
727
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000728- Issue #4069: When set.remove(element) is used with a set element, the element
729 is temporarily replaced with an equivalent frozenset. But the eventual
730 KeyError would always report the empty frozenset([]) as the missing key. Now
731 it correctly refers to the initial element.
732
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000733- Issue #4509: Various issues surrounding resize of bytearray objects to
734 which there are buffer exports.

744
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000745- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
746 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000748- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
749 returned them on 64bit platforms.
750
Walter Dörwalded960ac2009-05-03 22:36:33 +0000751- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
752 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
753 step. This avoids problems with counting UTF-8 bytes that ignores the effect
754 of using the replace error handler in PyUnicode_DecodeUTF8().
755
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000756- Issue #3739: The unicode-internal encoder now reports the number of characters
757 consumed like any other encoder (instead of the number of bytes).
758
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000759- Issue #2422: When compiled with the ``--with-valgrind`` option, the
760 pymalloc allocator will be automatically disabled when running under
761 Valgrind. This gives improved memory leak detection when running
762 under Valgrind, while taking advantage of pymalloc at other times.

2143
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002144- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2145 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2146 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2147 ``printf`` function, whereas PyString_FromFormat has an independent
2148 implementation and uses "%zd" on all platforms for size_t values.
2149 This makes a difference on win64, where ``printf`` needs "%Id" to display
2150 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002152- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2156 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00002166 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002167 was correctly parsed but parsing of subsequent arguments failed.
2168
Vinay Sajip35e3b032008-09-01 14:33:59 +00002169- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002170 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2171 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2172 when given a tuple of classes as second argument, were looking up
2173 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2174 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002313What's New in Python 2.6 beta 3?
2314================================
2315
Barry Warsaw07a4a382008-08-21 01:15:08 +00002316*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002317
2318Core and Builtins
2319-----------------
2320
Guido van Rossumf8402962008-08-20 15:01:50 +00002321- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2322 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2323 extensions do not automatically benefit from the class attribute
2324 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2325 to their tp_flags field if they care. This is a backwards
2326 compatibility feature; in 3.0, all types will use the cache by
2327 default.
2328
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002329- Keyword arguments can now follow starred arguments. (``f(a, *args,
2330 keyword=23)`` is now valid syntax.)
2331
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002332- ctypes function pointers that are COM methods have a boolean True
2333 value again.
2334
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002335- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2336 by denying s# to parse objects that have a releasebuffer procedure,
2337 and introducing s*.
2338
Georg Brandl1e13ea92008-08-11 09:07:59 +00002339- Issue #3537: Fix an assertion failure when an empty but presized dict
2340 object was stored in the freelist.
2341
Mark Dickinsonb6467572008-08-04 21:30:09 +00002342- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2343 ValueError consistently across platforms.
2344
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002345- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2346 (64bit Unix, for example), unichr() would truncate its argument and return
2347 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2348
Neal Norwitze7d8be82008-07-31 17:17:14 +00002349- Apply security patches from Apple.
2350
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002351- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2352 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2353
Antoine Pitrou92f82162008-07-25 22:22:08 +00002354- Issue #1819: function calls with several named parameters are now on
2355 average 35% faster (as measured by pybench).
2356
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002357- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2358 the python debugger steps into a class statement: the free variables (local
2359 variables defined in an outer scope) would be deleted from the outer scope.
2360
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002361- Issue #2620: Overflow checking when allocating or reallocating memory
2362 was not always being done properly in some python types and extension
2363 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2364 all been updated to perform better checks and places in the code that
2365 would previously leak memory on the error path when such an allocation
2366 failed have been fixed.
2367
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002368Library
2369-------
2370
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002371- Issue #3612: Added some missing basic types in ctypes.wintypes.
2372
Benjamin Petersone977ad42008-08-20 01:42:01 +00002373- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2374 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2375
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002376- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2377 version reported by these tools does not necessarily follow the python
2378 version numbering scheme, so the module is less strict when parsing it.
2379
Nick Coghlanf70385a2008-08-18 12:42:46 +00002380- Issue #2235: Added Py3k warnings for types which will become unhashable
2381 under the stricter __hash__ inheritance rules in 3.0. Several types
2382 which did not meet the rules for hash invariants and were already
2383 unhashable in 3.0 have now been explicitly flagged as unhashable in
2384 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2385 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2386
Brett Cannon88f801d2008-08-18 00:46:22 +00002387- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2388 imported into the module but exposed as part of the module's API.
2389
Brett Cannon7b96f072008-08-18 00:41:11 +00002390- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2391
Brett Cannon46225e72008-08-18 00:36:52 +00002392- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2393
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002394- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2395
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002396- Issue #3575: Incremental decoder's decode function now takes bytearray
2397 by using 's*' instead of 't#'.
2398
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002399- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002400 fails unicode conversion on 2nd parameter. (windows only)
2401
Facundo Batista94f243a2008-08-17 03:38:39 +00002402- Issue 2464. urllib2 now supports a malformation in the URL received
2403 in a redirect.
2404
Brett Cannonabe423e2008-08-16 21:47:07 +00002405- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002406 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002407
Facundo Batistaeb90b782008-08-16 14:44:07 +00002408- Issue #2776: fixed small issue when handling an URL with double slash
2409 after a 302 response in the case of not going through a proxy.
2410
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002411- Issue #2676: in the email package, content-type parsing was hanging on
2412 pathological input because of quadratic or exponential behaviour of a
2413 regular expression.
2414
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002415- Issue #3476: binary buffered reading through the new "io" library is now
2416 thread-safe.
2417
Brett Cannonbf3157b2008-08-14 05:00:03 +00002418- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2419 since mimetools itself is deprecated. Because modules are cached, all
2420 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2421
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002422- Issue #3134: shutil referenced undefined WindowsError symbol.
2423
Robert Schuppenies14646332008-08-10 11:01:53 +00002424- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2425 menu entries were not deleted.
2426
Brett Cannon83e81842008-08-09 23:30:55 +00002427- Copied the implementation of reduce() to _functools.reduce() to have a
2428 version that did not raise a DeprecationWarning under -3.
2429
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002430- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2431 a MemoryError rather than silently stop the iteration.
2432
Guido van Rossum59ce9012008-08-09 14:55:34 +00002433- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2434 to _sre.compile() will now be rejected. This should not affect anybody
2435 since the re.compile() function never generates invalid re-bytecode.
2436
Skip Montanaroa032bf42008-08-08 22:52:51 +00002437- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2438 upon first access it can be automatically initialized from the csv file if
2439 it wasn't initialized during instantiation.
2440
Brett Cannon3aa2a492008-08-06 22:28:09 +00002441- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2442 the reload() built-in has been removed.
2443
Brett Cannon7e30b672008-08-04 21:52:25 +00002444- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002445 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002452- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2453 raised an AttributeError.
2454
Benjamin Peterson01a24322008-07-28 23:35:27 +00002455- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002456 asking for a specific length. This problem only affected files opened
2457 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002458
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002459- Issue #3449: Update decimal module to use most recent specification
2460 (v. 1.68) and tests (v. 2.58) from IBM.
2461
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002462- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2470
2471- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2472 invalid arguments.
2473
2474- Issue #3302: Fix several crashes when calling locale's gettext functions
2475 with None arguments.
2476
2477- Issue #3389: Allow resolving dotted names for handlers in logging
2478 configuration files.
2479
2480- Deprecate the sunaudio module for removal in Python 3.0.
2481
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002482- Issue #3394: zipfile.writestr sets external attributes when passed a
2483 file name rather than a ZipInfo instance, so files are extracted with
2484 mode 0600 rather than 000 under Unix.
2485
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002486- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2487 argument in python 2.5, this broke code that subclassed Popen to include its
2488 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002498- Issue #2235: the C API function PyObject_HashNotImplemented and its
2499 interaction with the tp_hash slot (added in 2.6b2) are now documented
2500
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002501- Issue #643841: The language reference now provides more detailed
2502 coverage of the lookup process for special methods. The disclaimers
2503 regarding lack of coverage of new-style classes have also been
2504 removed, since the coverage is now fairly reasonable.

2508================================
2509
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002510*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002512Core and Builtins
2513-----------------
2514
Georg Brandl3e483f62008-07-16 22:57:41 +00002515- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2516 its methods now allow for items objects that can be converted to
2517 an integer using operator.index().
2518
Mark Dickinson64b7e502008-07-16 09:40:03 +00002519- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2520 produced a ValueError instead of giving the correct float.
2521
Eric Smitha5fa5a22008-07-16 00:11:49 +00002522- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2523 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2524
Mark Dickinson7103aa42008-07-15 19:08:33 +00002525- Issue #3008: the float type has a new instance method 'float.hex'
2526 and a new class method 'float.fromhex' to convert floating-point
2527 numbers to and from hexadecimal strings, respectively.
2528
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002529- Issue #2235: __hash__ is once again inherited by default. To allow
2530 collections.Hashable to remain meaningful in the presence of the
2531 default hash implementation (object.__hash__), it is now possible
2532 to explicit block inheritance of hash by setting __hash__=None at
2533 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2534 level.
2535
Nick Coghlanb028f502008-07-13 14:52:36 +00002536- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2537 the parent module cannot be found while performing an absolute import.
2538 This means that an incorrectly defined __package__ attribute will
2539 now only prevent relative imports in that module rather than causing
2540 all imports from that module to fail.
2541
Nick Coghlan14ff9942008-07-08 14:21:42 +00002542- Issue #2517: Allow unicode messages in Exceptions again by correctly
2543 bypassing the instance dictionary when looking up __unicode__ on
2544 new-style classes.
2545
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002546- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2547 set to a custom object whose write() method happens to install
2548 another file in sys.stdout.

2552 another thread's dictionary.
2553
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002554- Issue #3004: Minor change to slice.indices(): the start and stop
2555 arguments are now treated identically, making the behaviour easier
2556 to describe and understand. For example, slice(None, -10,
2557 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2558 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2559 10, -1).
2560
Georg Brandl278fc502008-07-19 12:46:12 +00002561- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00003013 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003014
3015 This is controlled by the configure argument ``--with-universal-archs``:

3018
3019 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3020
3021 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- Issue #1631171: Re-implement the 'warnings' module in C (the
3076 original Python code has been kept as backup). This will allow for
3077 using the 'warning's machinery in such places as the parser where
3078 use of pure Python code is not possible. Both the ``showarning()``
3079 and ``formatwarning()`` gain an optional 'line' argument which is
3080 not called by default for backwards-compatibility reasons. Setting
3081 ``warnings.showwarning()`` to an implementation that lacks support
3082 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003145- Issue #2550: The approach used by client/server code for obtaining
3146 ports to listen on in network-oriented tests has been refined in an
3147 effort to facilitate running multiple instances of the entire
3148 regression test suite in parallel without issue.
3149 test_support.bind_port() has been fixed such that it will always
3150 return a unique port -- which wasn't always the case with the
3151 previous implementation, especially if socket options had been set
3152 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3153 new implementation of bind_port() will actually raise an exception
3154 if it is passed an AF_INET/SOCK_STREAM socket with either the
3155 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3156 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3157 the socket it's been passed. This currently only applies to
3158 Windows. This option prevents any other sockets from binding to the
3159 host/port we've bound to, thus removing the possibility of the
3160 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3161 when a second SOCK_STREAM socket binds and accepts to a host/port
3162 that's already been bound by another socket. The optional preferred
3163 port parameter to bind_port() has been removed. Under no
3164 circumstances should tests be hard coding ports!
3165
3166 test_support.find_unused_port() has also been introduced, which will
3167 pass a temporary socket object to bind_port() in order to obtain an
3168 unused port. The temporary socket object is then closed and
3169 deleted, and the port is returned. This method should only be used
3170 for obtaining an unused port in order to pass to an external program
3171 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3172 a parameter to a server-oriented class that doesn't give you direct
3173 access to the underlying socket used.
3174
3175 Finally, test_support.HOST has been introduced, which should be used
3176 for the host argument of any relevant socket calls (i.e. bind and
3177 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003178
3179 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003180 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003181 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3182 test_asynchat and test_socket_ssl.
3183
Georg Brandl3ee81df2008-05-17 18:14:43 +00003184 It is now possible for multiple instances of the regression test
3185 suite to run in parallel without issue.

3452-----------------
3453
Fred Drakea8ee94b2008-03-01 02:45:07 +00003454- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003455 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003457- Issue #2067: file.__exit__() now calls subclasses' close() method.
3458
3459- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003460
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003461- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003462 issue 215555 for a discussion.
3463
Eric Smitha73fbe72008-02-23 03:09:44 +00003464- Added the future_builtins module, which contains hex() and oct().
3465 These are the PEP 3127 version of these functions, designed to be
3466 compatible with the hex() and oct() builtins from Python 3.0. They
3467 differ slightly in their output formats from the existing, unchanged
3468 Python 2.6 builtins. The expected usage of the future_builtins
3469 module is:
3470 from future_builtins import hex, oct
3471
Eric Smith7ef40bf2008-02-20 23:34:22 +00003472- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3473 exponents for exponents with absolute value < 100. Follows C99
3474 standard. This is a change on Windows, which would use 3 digits.
3475 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3476 so that any alterations it does to the resulting string will be
3477 available in stringlib/formatter.h (for float.__format__).
3478
Eric Smith5a3c1352008-02-19 13:21:56 +00003479- Implemented PEP 3101, Advanced String Formatting. This adds a new
3480 builtin format(); a format() method for str and unicode; a
3481 __format__() method to object, str, unicode, int, long, float, and
3482 datetime; the class string.Formatter; and the C API
3483 PyObject_Format().
3484
Georg Brandl3ee81df2008-05-17 18:14:43 +00003485- Fixed several potential crashes, all caused by specially crafted
3486 __del__ methods exploiting objects in temporarily inconsistent
3487 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003488
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003489- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003490 prevent a possible crash: an Abstract Base Class would try to access
3491 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003492
Georg Brandl3ee81df2008-05-17 18:14:43 +00003493- Fixed repr() and str() of complex numbers with infinity or nan as
3494 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003495
Georg Brandl3ee81df2008-05-17 18:14:43 +00003496- Clear all free lists during a gc.collect() of the highest generation
3497 in order to allow pymalloc to free more arenas. Python may give back
3498 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003499
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500- Issue #2045: Fix an infinite recursion triggered when printing a
3501 subclass of collections.defaultdict, if its default_factory is set
3502 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003503
Christian Heimesf75dbef2008-02-08 00:11:31 +00003504- Fixed a minor memory leak in dictobject.c. The content of the free
3505 list was not freed on interpreter shutdown.
3506
Georg Brandl3ee81df2008-05-17 18:14:43 +00003507- Limit free list of method and builtin function objects to 256
3508 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003509
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3511 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003512 to compact the internal free lists of pre-allocted ints and floats.
3513
Georg Brandl3ee81df2008-05-17 18:14:43 +00003514- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3515 calls. Python expected the return type int but the fork familie
3516 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003517
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3519 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003520

3528 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003529
Georg Brandl3ee81df2008-05-17 18:14:43 +00003530- Patch #1473257: generator objects gain a gi_code attribute. This is
3531 the same object as the func_code attribute of the function that
3532 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003533
Georg Brandl3ee81df2008-05-17 18:14:43 +00003534- Issue #1920: "while 0" statements were completely removed by the
3535 compiler, even in the presence of an "else" clause, which is
3536 supposed to be run when the condition is false. Now the compiler
3537 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003538
Guido van Rossumeead05f2008-01-24 18:21:02 +00003539- A few crashers fixed: weakref_in_del.py (issue #1377858);
3540 loosing_dict_ref.py (issue #1303614, test67.py);
3541 borrowed_ref_[34].py (not in tracker).
3542
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003543- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003544 suppressed while an extension is loaded by calling SetErrorMode in
3545 dynload_win.c. The error is still reported properly.
3546
Georg Brandl3ee81df2008-05-17 18:14:43 +00003547- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003548 several extension methods and modules do not work without unicode
3549 support.
3550
Georg Brandl26543b12008-01-21 18:36:51 +00003551- Issue #1882: when compiling code from a string, encoding cookies in the
3552 second line of code were not always recognized correctly.
3553
Georg Brandl14404b62008-01-19 19:27:05 +00003554- Issue #1679: "0x" was taken as a valid integer literal.
3555
Georg Brandl6caad7d2008-01-26 14:19:22 +00003556- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003557 added.
3558
Christian Heimesc94e2b52008-01-14 04:13:37 +00003559- sys.float_info / PyFloat_GetInfo: The floating point information
3560 object was converted from a dict to a specialized structseq object.
3561
Georg Brandl3ee81df2008-05-17 18:14:43 +00003562- Patch #1816: Added sys.flags structseq. It exposes the status of
3563 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003564
Georg Brandl3ee81df2008-05-17 18:14:43 +00003565- Objects/structseq.c: Implemented new structseq representation. The
3566 patch makes structseqs (e.g. the return value of os.stat) more
3567 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003568
Georg Brandl3ee81df2008-05-17 18:14:43 +00003569- Patch #1700288: added a type attribute cache that caches method

3627 file can now be directly executed by passing their name to the
3628 interpreter. The directory/zipfile is automatically inserted as the
3629 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003630
Georg Brandl3ee81df2008-05-17 18:14:43 +00003631- Issue #1265: Fix a problem with sys.settrace, if the tracing
3632 function uses a generator expression when at the same time the
3633 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003634
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003635- sets and frozensets now have an isdisjoint() method.
3636
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003637- optimize the performance of builtin.sum().
3638
Neal Norwitz44f326e2007-10-05 05:29:17 +00003639- Fix warnings found by the new version of the Coverity checker.
3640
Georg Brandl3ee81df2008-05-17 18:14:43 +00003641- The enumerate() builtin function is no longer bounded to sequences
3642 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3643 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003644
Georg Brandl3ee81df2008-05-17 18:14:43 +00003645- Issue #1686386: Tuple's tp_repr did not take into account the
3646 possibility of having a self-referential tuple, which is possible
3647 from C code. Nor did object's tp_str consider that a type's tp_str
3648 could do something that could lead to an inifinite recursion.
3649 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3650 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003651
Georg Brandl3ee81df2008-05-17 18:14:43 +00003652- Issue #1164: It was possible to trigger deadlock when using the
3653 'print' statement to write to a file since the GIL was not released
3654 as needed. Now PyObject_Print() does the right thing along with
3655 various tp_print implementations of the built-in types and those in
3656 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003657
Georg Brandl3ee81df2008-05-17 18:14:43 +00003658- Issue #1147: Exceptions were directly allowing string exceptions in
3659 their throw() method even though string exceptions no longer
3660 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003661
Georg Brandl3ee81df2008-05-17 18:14:43 +00003662- Issue #1096: Prevent a segfault from getting the repr of a very
3663 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003664
Brett Cannon1e534b52007-09-07 04:18:30 +00003665- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003666 PyObject_Call() never calling back out to Python code to trigger
3667 recursion depth updates/checks. Required the creation of a static
3668 RuntimeError instance in case normalizing an exception put the
3669 recursion check value past its limit. Fixes crashers
3670 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003671
Georg Brandl3ee81df2008-05-17 18:14:43 +00003672- Patch #1031213: Decode source line in SyntaxErrors back to its
3673 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00003675- Patch #1673759: add a missing overflow check when formatting floats
3676 with %G.
3677
Georg Brandl3ee81df2008-05-17 18:14:43 +00003678- Prevent expandtabs() on string and unicode objects from causing a
3679 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00003680

Georg Brandl3ee81df2008-05-17 18:14:43 +00003683- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00003684
Neal Norwitz0ac60192007-05-27 04:08:54 +00003685- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003686 __*__ attributes. (Some already existed, e.g., __doc__ and
3687 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003688
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003689- Add -3 option to the interpreter to warn about features that are
3690 deprecated and will be changed/removed in Python 3.0.
3691
Georg Brandl2134e752007-05-21 20:34:16 +00003692- Patch #1686487: you can now pass any mapping after '**' in function
3693 calls.
3694
Collin Winter62903052007-05-18 23:11:24 +00003695- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003696 "except E as target:". This is to provide forwards compatibility
3697 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003698
Brett Cannon229cee22007-05-05 01:34:02 +00003699- Deprecate BaseException.message as per PEP 352.
3700
Georg Brandl3ee81df2008-05-17 18:14:43 +00003701- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003702 inherited from a builtin base.
3703
Vinay Sajip8549ce32007-05-06 17:53:37 +00003704- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003705 setting a plain string, ie don't expand to single letter identifiers.
3706
Raymond Hettinger13936692007-04-11 18:40:58 +00003707- Request #1191699: Slices can now be pickled.
3708
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003709- Request #1193128: str.translate() now allows a None argument for
3710 translations that only remove characters without re-mapping the
3711 remaining characters.
3712
Georg Brandl5cb76c12007-03-21 09:00:39 +00003713- Patch #1682205: a TypeError while unpacking an iterable is no longer
3714 masked by a generic one with the message "unpack non-sequence".
3715
Neal Norwitzaa754b72007-03-21 06:39:48 +00003716- Remove unused file Python/fmod.c.
3717
Guido van Rossum143b5642007-03-23 04:58:42 +00003718- Bug #1683368: The object.__init__() and object.__new__() methods are
3719 now stricter in rejecting excess arguments. The only time when
3720 either allows excess arguments is when it is not overridden and the
3721 other one is. For backwards compatibility, when both are
3722 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003723 warning later). Also, type.__init__() insists on the same signature
3724 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003725
Georg Brandl3ee81df2008-05-17 18:14:43 +00003726- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3727 object to complex using its __complex__() method before falling back
3728 to the __float__() method. Therefore, the functions in the cmath
3729 module now can operate on objects that define a __complex__()
3730 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003731
Georg Brandl3ee81df2008-05-17 18:14:43 +00003732- Patch #1623563: allow __class__ assignment for classes with
3733 __slots__. The old and the new class are still required to have the
3734 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003735
Georg Brandl3ee81df2008-05-17 18:14:43 +00003736- Patch #1642547: Fix an error/crash when encountering syntax errors
3737 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- Patch #1462488: Python no longer segfaults when
3740 ``object.__reduce_ex__()`` is called with an object that is faking
3741 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003742
Georg Brandl3ee81df2008-05-17 18:14:43 +00003743- Patch #1680015: Don't modify __slots__ tuple if it contains an
3744 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00003745
Georg Brandl5240d742007-03-13 20:46:32 +00003746- Patch #1444529: the builtin compile() now accepts keyword arguments.
3747
Georg Brandl7b9c5552007-03-12 14:30:05 +00003748- Bug #1678647: write a newline after printing an exception in any
3749 case, even when converting the value to a string failed.
3750
Georg Brandl871f1bc2007-03-12 13:17:36 +00003751- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003752 its argument, if it exists. If not, it will work like before. This
3753 allows customizing the output of dir() in the presence of a
3754 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003755
Collin Winter276887b2007-03-12 16:11:39 +00003756- Patch #922167: Python no longer segfaults when faced with infinitely
3757 self-recursive reload() calls (as reported by bug #742342).
3758
Georg Brandl3ee81df2008-05-17 18:14:43 +00003759- Patch #1675981: remove unreachable code from ``type.__new__()``
3760 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00003761
Georg Brandl3ee81df2008-05-17 18:14:43 +00003762- Patch #1491866: change the complex() constructor to allow
3763 parthensized forms. This means complex(repr(x)) now works instead of
3764 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003765
Georg Brandlaa2321b2007-03-07 00:40:28 +00003766- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003767 makes the filenames the warning module prints much more sensible
3768 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003769
Georg Brandl49aafc92007-03-07 00:34:46 +00003770- Variant of patch #697613: don't exit the interpreter on a SystemExit
3771 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003772 variable is given, but break into the interactive interpreter just
3773 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00003774
Georg Brandl3ee81df2008-05-17 18:14:43 +00003775- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00003778- Bug #1674503: close the file opened by execfile() in an error
3779 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003780
Georg Brandl0fca97a2007-03-05 22:28:08 +00003781- Patch #1674228: when assigning a slice (old-style), check for the
3782 sq_ass_slice instead of the sq_slice slot.
3783
Georg Brandl3ee81df2008-05-17 18:14:43 +00003784- When printing an unraisable error, don't print exceptions. before
3785 the name. This duplicates the behavior whening normally printing
3786 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003787
Georg Brandl3ee81df2008-05-17 18:14:43 +00003788- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003794- Bug #1377858: Fix the segfaulting of the interpreter when an object
3795 created a weakref on itself during a __del__ call for new-style
3796 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00003797
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00003798- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

Georg Brandl2c1375c2006-10-12 11:27:59 +00003836- Bug #1545497: when given an explicit base, int() did ignore NULs
3837 embedded in the string to convert.
3838
Georg Brandl846f73a2006-10-08 07:11:54 +00003839- Bug #1569998: break inside a try statement (outside a loop) is now
3840 recognized and rejected.
3841

3843
Armin Rigo7ccbca92006-10-04 12:17:45 +00003844- A number of places, including integer negation and absolute value,
3845 were fixed to not rely on undefined behaviour of the C compiler
3846 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00003847
Georg Brandl3267d282006-09-30 09:03:42 +00003848- Bug #1566800: make sure that EnvironmentError can be called with any
3849 number of arguments, as was the case in Python 2.4.
3850
Georg Brandl5d59c092006-09-30 08:43:30 +00003851- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00003852 keyword arguments any more (previously they accepted them, but
3853 didn't use them).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- Fix a bug in the parser's future statement handling that led to
3856 "with" not being recognized as a keyword after, e.g., this
3857 statement: from __future__ import division, with_statement

4414 -- the failure just occurred later, with a more cumbersome
4415 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004696- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4697 with RFC 3207 and forgets any knowledge obtained from the server not
4698 obtained from the TLS negotiation itself. Patch contributed by Bill
4699 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004700
Georg Brandl3ee81df2008-05-17 18:14:43 +00004701- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004702 that the SMTP.starttls() caller no longer needs to call ehlo()
4703 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004704 does not claim to support starttls. Adds the
4705 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4786 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4787 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004789

Georg Brandl3ee81df2008-05-17 18:14:43 +00004804 time so that opening a database previously created with the DB_DUP
4805 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4806 opens. Specifically: dictionary assignment to a DB object will
4807 replace all values for a given key when the database allows
4808 duplicate values. DB users should use DB.put(k, v) when they want
4809 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004810

4816 characters with ASCII value less than 32. Also, it correctly quotes
4817 dots only if they occur on a single line, as opposed to the previous
4818 behavior of quoting dots if they are the second character of any
4819 line.

5142-----
5143
Georg Brandl3ee81df2008-05-17 18:14:43 +00005144- Unified naming convention for free lists and their limits. All free
5145 lists in Object/ are named ``free_list``, the counter ``numfree``
5146 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5147 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005148
Georg Brandl3ee81df2008-05-17 18:14:43 +00005149- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5150 to ``PyTuple_SetItem``, it can be used to populate a brand new
5151 frozenset; but it does not steal a reference to the added item.

5163
Georg Brandl3ee81df2008-05-17 18:14:43 +00005164- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5165 of w# format code incorrectly truncated the length to an int, even
5166 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5167 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005168
Georg Brandl3ee81df2008-05-17 18:14:43 +00005169- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5187- Fix some leftovers from the conversion from int to Py_ssize_t
5188 (relevant to strings and sequences of more than 2**31 items).
5189
5190- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5191 outside of pystate.c and should not be necessary.
5192
Georg Brandl3ee81df2008-05-17 18:14:43 +00005193- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5194 absolute imports. In earlier versions they might have used relative
5195 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005196
Georg Brandl3ee81df2008-05-17 18:14:43 +00005197- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5198 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005199
Georg Brandl3ee81df2008-05-17 18:14:43 +00005200- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5208 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5209 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5210 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005211

Georg Brandl3ee81df2008-05-17 18:14:43 +00005225- Removed the macfs module. It had been deprecated since Python 2.5.
5226 This lead to the deprecation of macostools.touched() as it relied
5227 solely on macfs and was a no-op under OS X.
