16 set to an non existent program name and Python is unable to retrieve the real
17 program name
18
Victor Stinner66644262010-03-10 22:30:19 +000019- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
20 (SIGINT). If an error occurs while importing the site module, the error is
21 printed and Python exits. Initialize the GIL before importing the site
22 module.

Vinay Sajipecfa08f2010-03-12 09:16:10 +000027- Issue #8117: logging: Improved algorithm for computing initial rollover time
28 for TimedRotatingFileHandler by using the modification time of an existing
29 log file to compute the next rollover time. If the log file does not exist,
30 the current time is used as the basis for the computation.

Florent Xicluna3e8c1892010-03-11 14:36:19 +000032- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
33 cElementTree module is updated too.

R. David Murray4617e502010-03-08 02:04:06 +000040- Issue #7143: get_payload used to strip any trailing newline from a
41 base64 transfer-encoded payload *after* decoding it; it no longer does.
42 This is a behavior change, so email's minor version number is now
43 bumped, to version 4.0.2, for the 2.7 release.

48- Issue #1530559: When passing a non-integer argument to struct.pack
49 with *any* integer format code (one of 'bBhHiIlLqQ'), struct.pack
50 attempts to use the argument's __int__ method to convert to an
51 integer before packing. It also produces a DeprecationWarning in
52 this case. (In Python 2.6, the behaviour was inconsistent: __int__
53 was used for some integer codes but not for others, and the set of
54 integer codes for which it was used differed between native packing
55 and standard packing.)

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000383What's New in Python 2.7 alpha 2?
384=================================
385
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000386*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000387
388Core and Builtins
389-----------------
390
Benjamin Petersonecdae192010-01-04 00:43:01 +0000391- The __complex__ method is now looked up on the class of instances to make it
392 consistent with other special methods.
393
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000394- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
395 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
396
Mark Dickinson1b34d252010-01-01 17:27:30 +0000397- Issue #5080: A number of functions and methods previously produced a
398 DeprecationWarning when passed a float argument where an integer was
399 expected. These functions and methods now raise TypeError instead.
400 The majority of the effects of this change are in the extension
401 modules, but some core functions and methods are affected: notably
402 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
403 methods.
404
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000405- Issue #7604: Deleting an unset slotted attribute did not raise an
406 AttributeError.
407
Mark Dickinson99d652e2009-12-30 12:12:23 +0000408- Issue #7534: Fix handling of IEEE specials (infinities, nans,
409 negative zero) in ** operator. The behaviour now conforms to that
410 described in C99 Annex F.
411
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000412- Issue #7579: the msvcrt module now has docstrings for all its functions.
413
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000414- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
415 used to drop the time part of the result.
416
Mark Dickinson46572832009-12-27 14:55:57 +0000417- Issue #1811: improve accuracy and cross-platform consistency for
418 true division of integers: the result of a/b is now correctly
419 rounded for ints a and b (at least on IEEE 754 platforms), and in
420 particular does not depend on the internal representation of a long.
421
Ezio Melottif84caf42009-12-24 22:25:17 +0000422- Issue #6108: unicode(exception) and str(exception) should return the same
423 message when only __str__ (and not __unicode__) is overridden in the subclass.
424
Ronald Oussoren92919a62009-12-24 13:30:58 +0000425- Issue #6834: replace the implementation for the 'python' and 'pythonw'
426 executables on OSX.
427
428 These executables now work properly with the arch(1) command:
429 ``arch -ppc python`` will start a universal binary version of python
430 in PPC mode (unlike previous releases).
431
R. David Murray0a0a1a82009-12-14 16:28:26 +0000432- Issue #1680159: unicode coercion during an 'in' operation no longer masks
433 the underlying error when the coercion fails for the left hand operand.
434
Benjamin Peterson4895af42009-12-13 16:36:53 +0000435- Issue #7491: Metaclass's __cmp__ method was ignored.
436
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000437- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +0000438 in the middle of populating a tuple. Patch by Florent Xicluna.

488
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000489- Issue #7349: Make methods of file objects in the io module accept None as an
490 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
491 the same as passing no argument.
492
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000493- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

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

566
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000567- Issue #7419: setlocale() could crash the interpreter on Windows when called
568 with invalid values.
569
Eric Smithc4ab8332009-11-29 17:40:57 +0000570- Issue #3382: 'F' formatting for float and complex now convert the
571 result to upper case. This only affects 'inf' and 'nan', since 'f'
572 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000573
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000574- Remove switch from "%f" formatting to "%g" formatting for floats
575 larger than 1e50 in absolute value.
576
Mark Dickinson18cfada2009-11-23 18:46:41 +0000577- Remove restrictions on precision when formatting floats. E.g.,
578 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
579 requested 120 significant digits instead.
580
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000581- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000585- Issue #7085: Fix crash when importing some extensions in a thread
586 on MacOSX 10.6.
587
Mark Dickinsonb678de82009-11-19 18:41:49 +0000588- Issue #7117: repr(x) for a float x returns a result based on the
589 shortest decimal string that's guaranteed to round back to x under
590 correct rounding (with round-half-to-even rounding mode).
591 Previously it gave a string based on rounding x to 17 decimal digits.
592 repr(x) for a complex number behaves similarly. On platforms where
593 the correctly-rounded strtod and dtoa code is not supported (see below),
594 repr is unchanged.
595
596- Issue #7117: On almost all platforms: float-to-string and
597 string-to-float conversions within Python are now correctly rounded.
598 Places these conversions occur include: str for floats and complex
599 numbers; the float and complex constructors; old-style and new-style
600 numeric formatting; serialization and deserialization of floats and
601 complex numbers using marshal, pickle and json; parsing of float and
602 imaginary literals in Python code; Decimal-to-float conversion.
603
604 The conversions use a Python-adapted version of David Gay's
605 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
606 functions. This code is supported on Windows, and on Unix-like
607 platforms using gcc, icc or suncc as the C compiler. There may be a
608 small number of platforms on which correct operation of this code
609 cannot be guaranteed, so the code is not used: notably, this applies
610 to platforms where the C double format is not IEEE 754 binary64, and
611 to platforms on x86 hardware where the x87 FPU is set to 64-bit
612 precision and Python's configure script is unable to determine how
613 to change the FPU precision. On these platforms conversions use the

Mark Dickinsonbd15a062009-11-18 19:33:35 +0000616- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000617 now uses the correctly-rounded string <-> float conversions
618 described above (when available), and so produces correctly rounded
619 results that will display nicely under the float repr. There are
620 two related small changes: (1) round now accepts any class with an
621 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000622 floats for the second argument), and (2) an excessively large second
623 integer argument (e.g., round(1.234, 10**100)) no longer raises an
624 exception.

Eric Smitha985a3a2009-05-05 18:26:08 +0000772- Issue #5920: For float.__format__, change the behavior with the
773 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
774 to be like 'g' but with at least one decimal point and with a
775 default precision of 12. Previously, the behavior the same but with
776 a default precision of 6. This more closely matches str(), and
777 reduces surprises when adding alignment flags to the empty
778 presentation type. This also affects the new complex.__format__ in
779 the same way.

913
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000914- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
915 collecting the oldest generation) so that allocating lots of objects without
916 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000917 Martin von Löwis at

921
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000922- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
923 an existing .py counterpart, override the co_filename attributes of all
924 code objects if the original filename is obsolete (which can happen if the
925 file has been renamed, moved, or if it is accessed through different paths).
926 Patch by Ziga Seilnacht and Jean-Paul Calderone.
927
Martin v. Löwis5344c992009-01-02 20:32:55 +0000928- Issue #4075: Use OutputDebugStringW in Py_FatalError.
929
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000930- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
931 file with `str' filename on Windows.
932
Antoine Pitrouaa687902009-01-01 14:11:22 +0000933- Issue #3680: Reference cycles created through a dict, set or deque iterator
934 did not get collected.
935
Nick Coghlan180e4002008-12-30 01:18:48 +0000936- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
937 where the tp_hash and tp_dict slots are both NULL.
938
Benjamin Peterson7af65562008-12-29 17:56:58 +0000939- Issue #4764: With io.open, IOError.filename is set when trying to open a
940 directory on POSIX systems.
941
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000942- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

946 bytearray.translate(). It was always allowed for bytes.translate().
947
Skip Montanarof205c132008-12-23 03:30:15 +0000948- Added test case to ensure attempts to read from a file opened for writing
949 fail.
950
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000951- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

962
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000963- Issue #4597: Fixed several opcodes that weren't always propagating
964 exceptions.
965
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000966- Issue #4445: Replace "sizeof(PyStringObject)" with
967 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
968 str instances. On a typical machine this saves 3 bytes of memory
969 (on average) per string allocation.
970
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000971- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
972 interpreter to abort ("Fatal Python error: Could not reset the stack!")
973 instead of throwing a MemoryError.
974
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000975- Issue #3689: The list reversed iterator now supports __length_hint__
976 instead of __len__. Behavior now matches other reversed iterators.
977
Benjamin Petersonc078f922008-11-21 22:27:24 +0000978- Issue #4367: Python would segfault during compiling when the unicodedata
979 module couldn't be imported and \N escapes were present.
980
Vinay Sajip213faca2008-12-03 23:22:58 +0000981- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000982 method on file objects with closefd=False. The file descriptor is still
983 kept open but the file object behaves like a closed file. The ``FileIO``
984 object also got a new readonly attribute ``closefd``.
985
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000986- Issue #4348: Some bytearray methods returned that didn't cause any change to
987 the bytearray, returned the same bytearray instead of a copy.
988
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000989- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
990
Benjamin Peterson273c2332008-11-17 22:39:09 +0000991- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
992
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000993- Issue #4048: The parser module now correctly validates relative imports.
994
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000995- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
996 exec statement.
997
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000998- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
999 method does not return iterators for the 4th and 5th items.
1000
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001001- Issue #4209: Enabling unicode_literals and the print_function in the same
1002 __future__ import didn't work.
1003
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001004- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001005 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001006
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001007- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1008 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1009 really executed because I cannot move to such directory on win2k)
1010
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00001011- Issue #4069: When set.remove(element) is used with a set element, the element
1012 is temporarily replaced with an equivalent frozenset. But the eventual
1013 KeyError would always report the empty frozenset([]) as the missing key. Now
1014 it correctly refers to the initial element.
1015
Antoine Pitrouae5bece2008-12-06 21:29:24 +00001016- Issue #4509: Various issues surrounding resize of bytearray objects to
1017 which there are buffer exports.
1018
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00001019- Issue #4748: Lambda generators no longer return a value.

1027
Matthias Klose91a3b9e2009-04-05 21:19:13 +00001028- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1029 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001031- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1032 returned them on 64bit platforms.
1033
Walter Dörwalded960ac2009-05-03 22:36:33 +00001034- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1035 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1036 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1037 of using the replace error handler in PyUnicode_DecodeUTF8().
1038
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001039- Issue #3739: The unicode-internal encoder now reports the number of characters
1040 consumed like any other encoder (instead of the number of bytes).
1041
Benjamin Peterson91c12eb2009-12-03 02:52:39 +00001042- Issue #2422: When compiled with the ``--with-valgrind`` option, the
1043 pymalloc allocator will be automatically disabled when running under
1044 Valgrind. This gives improved memory leak detection when running
1045 under Valgrind, while taking advantage of pymalloc at other times.

2430
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002431- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2432 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2433 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2434 ``printf`` function, whereas PyString_FromFormat has an independent
2435 implementation and uses "%zd" on all platforms for size_t values.
2436 This makes a difference on win64, where ``printf`` needs "%Id" to display
2437 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002439- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2443 object; previously an int would be returned for small values. the __long__
2444 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00002453 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002454 was correctly parsed but parsing of subsequent arguments failed.
2455
Vinay Sajip35e3b032008-09-01 14:33:59 +00002456- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002457 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2458 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2459 when given a tuple of classes as second argument, were looking up
2460 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2461 type object.

2561 without limit.
2562
Benjamin Peterson37346b22008-08-23 20:27:43 +00002563- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002600What's New in Python 2.6 beta 3?
2601================================
2602
Barry Warsaw07a4a382008-08-21 01:15:08 +00002603*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002604
2605Core and Builtins
2606-----------------
2607
Guido van Rossumf8402962008-08-20 15:01:50 +00002608- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2609 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2610 extensions do not automatically benefit from the class attribute
2611 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2612 to their tp_flags field if they care. This is a backwards
2613 compatibility feature; in 3.0, all types will use the cache by
2614 default.
2615
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002616- Keyword arguments can now follow starred arguments. (``f(a, *args,
2617 keyword=23)`` is now valid syntax.)
2618
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002619- ctypes function pointers that are COM methods have a boolean True
2620 value again.
2621
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002622- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2623 by denying s# to parse objects that have a releasebuffer procedure,
2624 and introducing s*.
2625
Georg Brandl1e13ea92008-08-11 09:07:59 +00002626- Issue #3537: Fix an assertion failure when an empty but presized dict
2627 object was stored in the freelist.
2628
Mark Dickinsonb6467572008-08-04 21:30:09 +00002629- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2630 ValueError consistently across platforms.
2631
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002632- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2633 (64bit Unix, for example), unichr() would truncate its argument and return
2634 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2635
Neal Norwitze7d8be82008-07-31 17:17:14 +00002636- Apply security patches from Apple.
2637
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002638- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2639 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2640
Antoine Pitrou92f82162008-07-25 22:22:08 +00002641- Issue #1819: function calls with several named parameters are now on
2642 average 35% faster (as measured by pybench).
2643
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002644- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2645 the python debugger steps into a class statement: the free variables (local
2646 variables defined in an outer scope) would be deleted from the outer scope.
2647
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002648- Issue #2620: Overflow checking when allocating or reallocating memory
2649 was not always being done properly in some python types and extension
2650 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2651 all been updated to perform better checks and places in the code that
2652 would previously leak memory on the error path when such an allocation
2653 failed have been fixed.
2654
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002655Library
2656-------
2657
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002658- Issue #3612: Added some missing basic types in ctypes.wintypes.
2659
Benjamin Petersone977ad42008-08-20 01:42:01 +00002660- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2661 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2662
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002663- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2664 version reported by these tools does not necessarily follow the python
2665 version numbering scheme, so the module is less strict when parsing it.
2666
Nick Coghlanf70385a2008-08-18 12:42:46 +00002667- Issue #2235: Added Py3k warnings for types which will become unhashable
2668 under the stricter __hash__ inheritance rules in 3.0. Several types
2669 which did not meet the rules for hash invariants and were already
2670 unhashable in 3.0 have now been explicitly flagged as unhashable in
2671 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2672 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2673
Brett Cannon88f801d2008-08-18 00:46:22 +00002674- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2675 imported into the module but exposed as part of the module's API.
2676
Brett Cannon7b96f072008-08-18 00:41:11 +00002677- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2678
Brett Cannon46225e72008-08-18 00:36:52 +00002679- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002681- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2682
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002683- Issue #3575: Incremental decoder's decode function now takes bytearray
2684 by using 's*' instead of 't#'.
2685
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002686- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002687 fails unicode conversion on 2nd parameter. (windows only)
2688
Facundo Batista94f243a2008-08-17 03:38:39 +00002689- Issue 2464. urllib2 now supports a malformation in the URL received
2690 in a redirect.
2691
Brett Cannonabe423e2008-08-16 21:47:07 +00002692- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002693 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002694
Facundo Batistaeb90b782008-08-16 14:44:07 +00002695- Issue #2776: fixed small issue when handling an URL with double slash
2696 after a 302 response in the case of not going through a proxy.
2697
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002698- Issue #2676: in the email package, content-type parsing was hanging on
2699 pathological input because of quadratic or exponential behaviour of a
2700 regular expression.
2701
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002702- Issue #3476: binary buffered reading through the new "io" library is now
2703 thread-safe.
2704
Brett Cannonbf3157b2008-08-14 05:00:03 +00002705- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2706 since mimetools itself is deprecated. Because modules are cached, all
2707 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2708
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002709- Issue #3134: shutil referenced undefined WindowsError symbol.
2710
Robert Schuppenies14646332008-08-10 11:01:53 +00002711- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2712 menu entries were not deleted.
2713
Brett Cannon83e81842008-08-09 23:30:55 +00002714- Copied the implementation of reduce() to _functools.reduce() to have a
2715 version that did not raise a DeprecationWarning under -3.
2716
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002717- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2718 a MemoryError rather than silently stop the iteration.
2719
Guido van Rossum59ce9012008-08-09 14:55:34 +00002720- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2721 to _sre.compile() will now be rejected. This should not affect anybody
2722 since the re.compile() function never generates invalid re-bytecode.
2723
Skip Montanaroa032bf42008-08-08 22:52:51 +00002724- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2725 upon first access it can be automatically initialized from the csv file if
2726 it wasn't initialized during instantiation.
2727
Brett Cannon3aa2a492008-08-06 22:28:09 +00002728- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2729 the reload() built-in has been removed.
2730
Brett Cannon7e30b672008-08-04 21:52:25 +00002731- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002732 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002739- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2740 raised an AttributeError.
2741
Benjamin Peterson01a24322008-07-28 23:35:27 +00002742- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002743 asking for a specific length. This problem only affected files opened
2744 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002745
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002746- Issue #3449: Update decimal module to use most recent specification
2747 (v. 1.68) and tests (v. 2.58) from IBM.
2748
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002749- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2757
2758- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2759 invalid arguments.
2760
2761- Issue #3302: Fix several crashes when calling locale's gettext functions
2762 with None arguments.
2763
2764- Issue #3389: Allow resolving dotted names for handlers in logging
2765 configuration files.
2766
2767- Deprecate the sunaudio module for removal in Python 3.0.
2768
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002769- Issue #3394: zipfile.writestr sets external attributes when passed a
2770 file name rather than a ZipInfo instance, so files are extracted with
2771 mode 0600 rather than 000 under Unix.
2772
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002773- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2774 argument in python 2.5, this broke code that subclassed Popen to include its
2775 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002785- Issue #2235: the C API function PyObject_HashNotImplemented and its
2786 interaction with the tp_hash slot (added in 2.6b2) are now documented
2787
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002788- Issue #643841: The language reference now provides more detailed
2789 coverage of the lookup process for special methods. The disclaimers
2790 regarding lack of coverage of new-style classes have also been
2791 removed, since the coverage is now fairly reasonable.

2800-----------------
2801
Georg Brandl3e483f62008-07-16 22:57:41 +00002802- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2803 its methods now allow for items objects that can be converted to
2804 an integer using operator.index().
2805
Mark Dickinson64b7e502008-07-16 09:40:03 +00002806- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2807 produced a ValueError instead of giving the correct float.
2808
Eric Smitha5fa5a22008-07-16 00:11:49 +00002809- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2810 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2811
Mark Dickinson7103aa42008-07-15 19:08:33 +00002812- Issue #3008: the float type has a new instance method 'float.hex'
2813 and a new class method 'float.fromhex' to convert floating-point
2814 numbers to and from hexadecimal strings, respectively.
2815
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002816- Issue #2235: __hash__ is once again inherited by default. To allow
2817 collections.Hashable to remain meaningful in the presence of the
2818 default hash implementation (object.__hash__), it is now possible
2819 to explicit block inheritance of hash by setting __hash__=None at
2820 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2821 level.
2822
Nick Coghlanb028f502008-07-13 14:52:36 +00002823- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2824 the parent module cannot be found while performing an absolute import.
2825 This means that an incorrectly defined __package__ attribute will
2826 now only prevent relative imports in that module rather than causing
2827 all imports from that module to fail.
2828
Nick Coghlan14ff9942008-07-08 14:21:42 +00002829- Issue #2517: Allow unicode messages in Exceptions again by correctly
2830 bypassing the instance dictionary when looking up __unicode__ on
2831 new-style classes.
2832
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002833- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2834 set to a custom object whose write() method happens to install
2835 another file in sys.stdout.

2839 another thread's dictionary.
2840
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002841- Issue #3004: Minor change to slice.indices(): the start and stop
2842 arguments are now treated identically, making the behaviour easier
2843 to describe and understand. For example, slice(None, -10,
2844 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2845 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2846 10, -1).
2847
Georg Brandl278fc502008-07-19 12:46:12 +00002848- Issue #3219: Calling a function with repeated keyword arguments,
2849 f(a=2, a=23), would not cause a syntax error. This was a regression
2850 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00003300 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003301
3302 This is controlled by the configure argument ``--with-universal-archs``:
3303
3304 - ``--with-universal-archs=all``: install 4-way universal
3305
3306 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3307
3308 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3309

3349 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003362- Issue #1631171: Re-implement the 'warnings' module in C (the
3363 original Python code has been kept as backup). This will allow for
3364 using the 'warning's machinery in such places as the parser where
3365 use of pure Python code is not possible. Both the ``showarning()``
3366 and ``formatwarning()`` gain an optional 'line' argument which is
3367 not called by default for backwards-compatibility reasons. Setting
3368 ``warnings.showwarning()`` to an implementation that lacks support
3369 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003432- Issue #2550: The approach used by client/server code for obtaining
3433 ports to listen on in network-oriented tests has been refined in an
3434 effort to facilitate running multiple instances of the entire
3435 regression test suite in parallel without issue.
3436 test_support.bind_port() has been fixed such that it will always
3437 return a unique port -- which wasn't always the case with the
3438 previous implementation, especially if socket options had been set
3439 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3440 new implementation of bind_port() will actually raise an exception
3441 if it is passed an AF_INET/SOCK_STREAM socket with either the
3442 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3443 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3444 the socket it's been passed. This currently only applies to
3445 Windows. This option prevents any other sockets from binding to the
3446 host/port we've bound to, thus removing the possibility of the
3447 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3448 when a second SOCK_STREAM socket binds and accepts to a host/port
3449 that's already been bound by another socket. The optional preferred
3450 port parameter to bind_port() has been removed. Under no
3451 circumstances should tests be hard coding ports!
3452
3453 test_support.find_unused_port() has also been introduced, which will
3454 pass a temporary socket object to bind_port() in order to obtain an
3455 unused port. The temporary socket object is then closed and
3456 deleted, and the port is returned. This method should only be used
3457 for obtaining an unused port in order to pass to an external program
3458 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3459 a parameter to a server-oriented class that doesn't give you direct
3460 access to the underlying socket used.
3461
3462 Finally, test_support.HOST has been introduced, which should be used
3463 for the host argument of any relevant socket calls (i.e. bind and
3464 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003465
3466 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003467 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003468 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3469 test_asynchat and test_socket_ssl.
3470
Georg Brandl3ee81df2008-05-17 18:14:43 +00003471 It is now possible for multiple instances of the regression test
3472 suite to run in parallel without issue.

3740
Fred Drakea8ee94b2008-03-01 02:45:07 +00003741- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003742 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003744- Issue #2067: file.__exit__() now calls subclasses' close() method.
3745
3746- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003747
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003748- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003749 issue 215555 for a discussion.
3750
Eric Smitha73fbe72008-02-23 03:09:44 +00003751- Added the future_builtins module, which contains hex() and oct().
3752 These are the PEP 3127 version of these functions, designed to be
3753 compatible with the hex() and oct() builtins from Python 3.0. They
3754 differ slightly in their output formats from the existing, unchanged
3755 Python 2.6 builtins. The expected usage of the future_builtins
3756 module is:
3757 from future_builtins import hex, oct
3758
Eric Smith7ef40bf2008-02-20 23:34:22 +00003759- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3760 exponents for exponents with absolute value < 100. Follows C99
3761 standard. This is a change on Windows, which would use 3 digits.
3762 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3763 so that any alterations it does to the resulting string will be
3764 available in stringlib/formatter.h (for float.__format__).
3765
Eric Smith5a3c1352008-02-19 13:21:56 +00003766- Implemented PEP 3101, Advanced String Formatting. This adds a new
3767 builtin format(); a format() method for str and unicode; a
3768 __format__() method to object, str, unicode, int, long, float, and
3769 datetime; the class string.Formatter; and the C API
3770 PyObject_Format().
3771
Georg Brandl3ee81df2008-05-17 18:14:43 +00003772- Fixed several potential crashes, all caused by specially crafted
3773 __del__ methods exploiting objects in temporarily inconsistent
3774 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003775
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003776- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003777 prevent a possible crash: an Abstract Base Class would try to access
3778 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003779

Georg Brandl3ee81df2008-05-17 18:14:43 +00003783- Clear all free lists during a gc.collect() of the highest generation
3784 in order to allow pymalloc to free more arenas. Python may give back
3785 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003786
Georg Brandl3ee81df2008-05-17 18:14:43 +00003787- Issue #2045: Fix an infinite recursion triggered when printing a
3788 subclass of collections.defaultdict, if its default_factory is set
3789 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003790
Christian Heimesf75dbef2008-02-08 00:11:31 +00003791- Fixed a minor memory leak in dictobject.c. The content of the free
3792 list was not freed on interpreter shutdown.
3793
Georg Brandl21e99f42010-03-07 15:23:59 +00003794- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003795 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003796
Georg Brandl3ee81df2008-05-17 18:14:43 +00003797- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3798 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003799 to compact the internal free lists of pre-allocted ints and floats.
3800
Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3802 calls. Python expected the return type int but the fork familie
3803 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003804
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3806 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003807

3815 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003816
Georg Brandl3ee81df2008-05-17 18:14:43 +00003817- Patch #1473257: generator objects gain a gi_code attribute. This is
3818 the same object as the func_code attribute of the function that
3819 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003820
Georg Brandl3ee81df2008-05-17 18:14:43 +00003821- Issue #1920: "while 0" statements were completely removed by the
3822 compiler, even in the presence of an "else" clause, which is
3823 supposed to be run when the condition is false. Now the compiler
3824 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003825
Guido van Rossumeead05f2008-01-24 18:21:02 +00003826- A few crashers fixed: weakref_in_del.py (issue #1377858);
3827 loosing_dict_ref.py (issue #1303614, test67.py);
3828 borrowed_ref_[34].py (not in tracker).
3829
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003830- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003831 suppressed while an extension is loaded by calling SetErrorMode in
3832 dynload_win.c. The error is still reported properly.
3833
Georg Brandl3ee81df2008-05-17 18:14:43 +00003834- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003835 several extension methods and modules do not work without unicode
3836 support.
3837
Georg Brandl26543b12008-01-21 18:36:51 +00003838- Issue #1882: when compiling code from a string, encoding cookies in the
3839 second line of code were not always recognized correctly.
3840
Georg Brandl14404b62008-01-19 19:27:05 +00003841- Issue #1679: "0x" was taken as a valid integer literal.
3842
Georg Brandl6caad7d2008-01-26 14:19:22 +00003843- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003844 added.
3845
Christian Heimesc94e2b52008-01-14 04:13:37 +00003846- sys.float_info / PyFloat_GetInfo: The floating point information
3847 object was converted from a dict to a specialized structseq object.
3848
Georg Brandl3ee81df2008-05-17 18:14:43 +00003849- Patch #1816: Added sys.flags structseq. It exposes the status of
3850 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003851
Georg Brandl3ee81df2008-05-17 18:14:43 +00003852- Objects/structseq.c: Implemented new structseq representation. The
3853 patch makes structseqs (e.g. the return value of os.stat) more
3854 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003855
Georg Brandl3ee81df2008-05-17 18:14:43 +00003856- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003878 and INF. float("nan"), float("inf") and float("-inf") now work on
3879 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003880
Georg Brandl3ee81df2008-05-17 18:14:43 +00003881- Compiler now generates simpler and faster code for dictionary
3882 literals. The oparg for BUILD_MAP now indicates an estimated
3883 dictionary size. There is a new opcode, STORE_MAP, for adding
3884 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003913- Patch #1739468: Directories and zipfiles containing a __main__.py
3914 file can now be directly executed by passing their name to the
3915 interpreter. The directory/zipfile is automatically inserted as the
3916 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003918- Issue #1265: Fix a problem with sys.settrace, if the tracing
3919 function uses a generator expression when at the same time the
3920 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003921
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003922- sets and frozensets now have an isdisjoint() method.

3925
Neal Norwitz44f326e2007-10-05 05:29:17 +00003926- Fix warnings found by the new version of the Coverity checker.
3927
Georg Brandl21e99f42010-03-07 15:23:59 +00003928- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003929 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3930 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003931
Georg Brandl3ee81df2008-05-17 18:14:43 +00003932- Issue #1686386: Tuple's tp_repr did not take into account the
3933 possibility of having a self-referential tuple, which is possible
3934 from C code. Nor did object's tp_str consider that a type's tp_str
3935 could do something that could lead to an inifinite recursion.
3936 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3937 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003938
Georg Brandl3ee81df2008-05-17 18:14:43 +00003939- Issue #1164: It was possible to trigger deadlock when using the
3940 'print' statement to write to a file since the GIL was not released
3941 as needed. Now PyObject_Print() does the right thing along with
3942 various tp_print implementations of the built-in types and those in
3943 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003944
Georg Brandl3ee81df2008-05-17 18:14:43 +00003945- Issue #1147: Exceptions were directly allowing string exceptions in
3946 their throw() method even though string exceptions no longer
3947 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003948
Georg Brandl3ee81df2008-05-17 18:14:43 +00003949- Issue #1096: Prevent a segfault from getting the repr of a very
3950 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003951
Brett Cannon1e534b52007-09-07 04:18:30 +00003952- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003953 PyObject_Call() never calling back out to Python code to trigger
3954 recursion depth updates/checks. Required the creation of a static
3955 RuntimeError instance in case normalizing an exception put the
3956 recursion check value past its limit. Fixes crashers
3957 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003958
Georg Brandl3ee81df2008-05-17 18:14:43 +00003959- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003972- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003973 __*__ attributes. (Some already existed, e.g., __doc__ and
3974 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003975
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003976- Add -3 option to the interpreter to warn about features that are
3977 deprecated and will be changed/removed in Python 3.0.
3978
Georg Brandl2134e752007-05-21 20:34:16 +00003979- Patch #1686487: you can now pass any mapping after '**' in function
3980 calls.
3981
Collin Winter62903052007-05-18 23:11:24 +00003982- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003983 "except E as target:". This is to provide forwards compatibility
3984 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003985
Brett Cannon229cee22007-05-05 01:34:02 +00003986- Deprecate BaseException.message as per PEP 352.
3987
Georg Brandl3ee81df2008-05-17 18:14:43 +00003988- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00003989 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003990
Vinay Sajip8549ce32007-05-06 17:53:37 +00003991- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003992 setting a plain string, ie don't expand to single letter identifiers.
3993
Raymond Hettinger13936692007-04-11 18:40:58 +00003994- Request #1191699: Slices can now be pickled.
3995
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003996- Request #1193128: str.translate() now allows a None argument for
3997 translations that only remove characters without re-mapping the
3998 remaining characters.
3999
Georg Brandl5cb76c12007-03-21 09:00:39 +00004000- Patch #1682205: a TypeError while unpacking an iterable is no longer
4001 masked by a generic one with the message "unpack non-sequence".
4002
Neal Norwitzaa754b72007-03-21 06:39:48 +00004003- Remove unused file Python/fmod.c.
4004
Guido van Rossum143b5642007-03-23 04:58:42 +00004005- Bug #1683368: The object.__init__() and object.__new__() methods are
4006 now stricter in rejecting excess arguments. The only time when
4007 either allows excess arguments is when it is not overridden and the
4008 other one is. For backwards compatibility, when both are
4009 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004010 warning later). Also, type.__init__() insists on the same signature
4011 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004012
Georg Brandl3ee81df2008-05-17 18:14:43 +00004013- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4014 object to complex using its __complex__() method before falling back
4015 to the __float__() method. Therefore, the functions in the cmath
4016 module now can operate on objects that define a __complex__()
4017 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004018
Georg Brandl3ee81df2008-05-17 18:14:43 +00004019- Patch #1623563: allow __class__ assignment for classes with
4020 __slots__. The old and the new class are still required to have the
4021 same slot names.

4027 ``object.__reduce_ex__()`` is called with an object that is faking
4028 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004029
Georg Brandl3ee81df2008-05-17 18:14:43 +00004030- Patch #1680015: Don't modify __slots__ tuple if it contains an

4034
Georg Brandl7b9c5552007-03-12 14:30:05 +00004035- Bug #1678647: write a newline after printing an exception in any
4036 case, even when converting the value to a string failed.
4037
Georg Brandl871f1bc2007-03-12 13:17:36 +00004038- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039 its argument, if it exists. If not, it will work like before. This
4040 allows customizing the output of dir() in the presence of a
4041 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004049- Patch #1491866: change the complex() constructor to allow
4050 parthensized forms. This means complex(repr(x)) now works instead of
4051 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004052
Georg Brandlaa2321b2007-03-07 00:40:28 +00004053- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004054 makes the filenames the warning module prints much more sensible
4055 when a PYTHONSTARTUP file is used.

Georg Brandl098cd692007-03-06 12:17:50 +00004067
Georg Brandl0fca97a2007-03-05 22:28:08 +00004068- Patch #1674228: when assigning a slice (old-style), check for the
4069 sq_ass_slice instead of the sq_slice slot.
4070
Georg Brandl3ee81df2008-05-17 18:14:43 +00004071- When printing an unraisable error, don't print exceptions. before
4072 the name. This duplicates the behavior whening normally printing
4073 exceptions.

4702 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004983- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4984 with RFC 3207 and forgets any knowledge obtained from the server not
4985 obtained from the TLS negotiation itself. Patch contributed by Bill
4986 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004987
Georg Brandl3ee81df2008-05-17 18:14:43 +00004988- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004989 that the SMTP.starttls() caller no longer needs to call ehlo()
4990 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004991 does not claim to support starttls. Adds the
4992 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5073 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5074 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005091 time so that opening a database previously created with the DB_DUP
5092 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5093 opens. Specifically: dictionary assignment to a DB object will
5094 replace all values for a given key when the database allows
5095 duplicate values. DB users should use DB.put(k, v) when they want
5096 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005097

5103 characters with ASCII value less than 32. Also, it correctly quotes
5104 dots only if they occur on a single line, as opposed to the previous
5105 behavior of quoting dots if they are the second character of any
5106 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005107

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005375- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005376 periodic threadstate and signal checking in tight loops. By
5377 default, this option is turned-off. It should only be enabled in
5378 debugged, performance critical applications.

5430
Georg Brandl3ee81df2008-05-17 18:14:43 +00005431- Unified naming convention for free lists and their limits. All free
5432 lists in Object/ are named ``free_list``, the counter ``numfree``

5434 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005435
Georg Brandl3ee81df2008-05-17 18:14:43 +00005436- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5437 to ``PyTuple_SetItem``, it can be used to populate a brand new
5438 frozenset; but it does not steal a reference to the added item.

5450
Georg Brandl3ee81df2008-05-17 18:14:43 +00005451- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5452 of w# format code incorrectly truncated the length to an int, even
5453 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5454 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005455
Georg Brandl3ee81df2008-05-17 18:14:43 +00005456- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5476
5477- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5478 outside of pystate.c and should not be necessary.
5479
Georg Brandl3ee81df2008-05-17 18:14:43 +00005480- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5481 absolute imports. In earlier versions they might have used relative
5482 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005483
Georg Brandl3ee81df2008-05-17 18:14:43 +00005484- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5485 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005486
Georg Brandl3ee81df2008-05-17 18:14:43 +00005487- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

5497 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005498

Georg Brandl3ee81df2008-05-17 18:14:43 +00005512- Removed the macfs module. It had been deprecated since Python 2.5.
5513 This lead to the deprecation of macostools.touched() as it relied
