Vinay Sajipecfa08f2010-03-12 09:16:10 +000027- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +000028 for ``TimedRotatingFileHandler`` by using the modification time of an
29 existing log file to compute the next rollover time. If the log file does
30 not exist, the current time is used as the basis for the computation.

41 a 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 bumped, to
43 version 4.0.2, for the 2.7 release.

Georg Brandlba83f822010-03-14 09:50:54 +000052- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
53 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
54 argument's __int__ method to convert to an integer before packing. It also
55 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
56 was inconsistent: __int__ was used for some integer codes but not for others,
57 and the set of integer codes for which it was used differed between native
58 packing and standard packing.)

402Core and Builtins
403-----------------
404
Georg Brandlba83f822010-03-14 09:50:54 +0000405- The ``__complex__()`` method is now looked up on the class of instances to
406 make it consistent with other special methods.

410
Mark Dickinson1b34d252010-01-01 17:27:30 +0000411- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000412 DeprecationWarning when passed a float argument where an integer was expected.
413 These functions and methods now raise TypeError instead. The majority of the
414 effects of this change are in the extension modules, but some core functions
415 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
416 and many unicode/str methods.

428
Georg Brandlba83f822010-03-14 09:50:54 +0000429- Issue #1811: Improve accuracy and cross-platform consistency for true division
430 of integers: the result of a/b is now correctly rounded for ints a and b (at
431 least on IEEE 754 platforms), and in particular does not depend on the
432 internal representation of a long.

440
Georg Brandlba83f822010-03-14 09:50:54 +0000441 These executables now work properly with the arch(1) command: ``arch -ppc
442 python`` will start a universal binary version of python in PPC mode (unlike
443 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000599- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
600 decimal string that's guaranteed to round back to x under correct rounding
601 (with round-half-to-even rounding mode). Previously it gave a string based on
602 rounding x to 17 decimal digits. repr(x) for a complex number behaves
603 similarly. On platforms where the correctly-rounded strtod and dtoa code is
604 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000605
Georg Brandlba83f822010-03-14 09:50:54 +0000606- Issue #7117: On almost all platforms: float-to-string and string-to-float
607 conversions within Python are now correctly rounded. Places these conversions
608 occur include: str for floats and complex numbers; the float and complex
609 constructors; old-style and new-style numeric formatting; serialization and
610 deserialization of floats and complex numbers using marshal, pickle and json;
611 parsing of float and imaginary literals in Python code; Decimal-to-float
612 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000613
Georg Brandlba83f822010-03-14 09:50:54 +0000614 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
615 providing correctly-rounded strtod and dtoa C functions. This code is
616 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
617 the C compiler. There may be a small number of platforms on which correct
618 operation of this code cannot be guaranteed, so the code is not used: notably,
619 this applies to platforms where the C double format is not IEEE 754 binary64,
620 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
621 and Python's configure script is unable to determine how to change the FPU
622 precision. On these platforms conversions use the platform strtod and dtoa,
623 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000625- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
626 uses the correctly-rounded string <-> float conversions described above (when
627 available), and so produces correctly rounded results that will display nicely
628 under the float repr. There are two related small changes: (1) round now
629 accepts any class with an ``__index__()`` method for its second argument (but
630 no longer accepts floats for the second argument), and (2) an excessively
631 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
632 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000774
Georg Brandlba83f822010-03-14 09:50:54 +0000775 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
776 (2) parsing of strings representing infinities and nans was locale aware; and
777 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +0000778
Georg Brandlba83f822010-03-14 09:50:54 +0000779- Issue #5920: For ``float.__format__()``, change the behavior with the empty
780 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
781 but with at least one decimal point and with a default precision
782 of 12. Previously, the behavior the same but with a default precision of 6.
783 This more closely matches ``str()``, and reduces surprises when adding
784 alignment flags to the empty presentation type. This also affects the new
785 complex.__format__ in the same way.
786
787- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
788 classtype's, even if it was None. property now inserts the __doc__ into the
789 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +0000850 untrackable objects are not tracked by the garbage collector. This can reduce

969 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
970 instances. On a typical machine this saves 3 bytes of memory (on average) per
971 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000973- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

975 instead of throwing a MemoryError.
976
Georg Brandlba83f822010-03-14 09:50:54 +0000977- Issue #3689: The list reversed iterator now supports __length_hint__ instead

982
Georg Brandlba83f822010-03-14 09:50:54 +0000983- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
984 file objects with closefd=False. The file descriptor is still kept open but
985 the file object behaves like a closed file. The ``FileIO`` object also got a
986 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001006- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001009- On windows, ``os.chdir()`` given unicode was not working if
1010 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1011 this code path is really executed because I cannot move to such directory on
1012 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001014- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1015 element is temporarily replaced with an equivalent frozenset. But the
1016 eventual KeyError would always report the empty ``frozenset()`` as the missing
1017 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001037- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1038 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1039 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1040 of using the replace error handler in PyUnicode_DecodeUTF8().
1041
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001042- Issue #3739: The unicode-internal encoder now reports the number of characters

1044
Georg Brandlba83f822010-03-14 09:50:54 +00001045- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1046 allocator will be automatically disabled when running under Valgrind. This
1047 gives improved memory leak detection when running under Valgrind, while taking
1048 advantage of pymalloc at other times.

2215 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2216 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002413- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2414
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002415- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2416 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2417 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2418 ``printf`` function, whereas PyString_FromFormat has an independent
2419 implementation and uses "%zd" on all platforms for size_t values.
2420 This makes a difference on win64, where ``printf`` needs "%Id" to display
2421 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002423- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2427 object; previously an int would be returned for small values. the __long__
2428 method is allowed to return either an int or a long, but the behaviour of
2429 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002431- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002437 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002438 was correctly parsed but parsing of subsequent arguments failed.
2439
Vinay Sajip35e3b032008-09-01 14:33:59 +00002440- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002441 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2442 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2443 when given a tuple of classes as second argument, were looking up
2444 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2445 type object.

2590-----------------
2591
Guido van Rossumf8402962008-08-20 15:01:50 +00002592- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2593 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2594 extensions do not automatically benefit from the class attribute
2595 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2596 to their tp_flags field if they care. This is a backwards
2597 compatibility feature; in 3.0, all types will use the cache by
2598 default.
2599
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002600- Keyword arguments can now follow starred arguments. (``f(a, *args,
2601 keyword=23)`` is now valid syntax.)
2602
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002603- ctypes function pointers that are COM methods have a boolean True
2604 value again.

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002606- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2607 by denying s# to parse objects that have a releasebuffer procedure,
2608 and introducing s*.
2609
Georg Brandl1e13ea92008-08-11 09:07:59 +00002610- Issue #3537: Fix an assertion failure when an empty but presized dict
2611 object was stored in the freelist.
2612
Mark Dickinsonb6467572008-08-04 21:30:09 +00002613- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2614 ValueError consistently across platforms.
2615
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002616- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2617 (64bit Unix, for example), unichr() would truncate its argument and return
2618 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2619
Neal Norwitze7d8be82008-07-31 17:17:14 +00002620- Apply security patches from Apple.
2621
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002622- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

2624
Antoine Pitrou92f82162008-07-25 22:22:08 +00002625- Issue #1819: function calls with several named parameters are now on
2626 average 35% faster (as measured by pybench).
2627
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002628- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2629 the python debugger steps into a class statement: the free variables (local
2630 variables defined in an outer scope) would be deleted from the outer scope.
2631
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002632- Issue #2620: Overflow checking when allocating or reallocating memory
2633 was not always being done properly in some python types and extension
2634 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2635 all been updated to perform better checks and places in the code that
2636 would previously leak memory on the error path when such an allocation
2637 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00002644- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2645 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2646
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002647- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2648 version reported by these tools does not necessarily follow the python
2649 version numbering scheme, so the module is less strict when parsing it.
2650
Nick Coghlanf70385a2008-08-18 12:42:46 +00002651- Issue #2235: Added Py3k warnings for types which will become unhashable
2652 under the stricter __hash__ inheritance rules in 3.0. Several types
2653 which did not meet the rules for hash invariants and were already
2654 unhashable in 3.0 have now been explicitly flagged as unhashable in
2655 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2656 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2657
Brett Cannon88f801d2008-08-18 00:46:22 +00002658- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2659 imported into the module but exposed as part of the module's API.
2660
Brett Cannon7b96f072008-08-18 00:41:11 +00002661- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2662
Brett Cannon46225e72008-08-18 00:36:52 +00002663- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2666
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002667- Issue #3575: Incremental decoder's decode function now takes bytearray
2668 by using 's*' instead of 't#'.
2669
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002670- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002671 fails unicode conversion on 2nd parameter. (windows only)
2672
Facundo Batista94f243a2008-08-17 03:38:39 +00002673- Issue 2464. urllib2 now supports a malformation in the URL received
2674 in a redirect.
2675
Brett Cannonabe423e2008-08-16 21:47:07 +00002676- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002677 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002678
Facundo Batistaeb90b782008-08-16 14:44:07 +00002679- Issue #2776: fixed small issue when handling an URL with double slash
2680 after a 302 response in the case of not going through a proxy.
2681
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002682- Issue #2676: in the email package, content-type parsing was hanging on
2683 pathological input because of quadratic or exponential behaviour of a
2684 regular expression.
2685
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002686- Issue #3476: binary buffered reading through the new "io" library is now
2687 thread-safe.
2688
Brett Cannonbf3157b2008-08-14 05:00:03 +00002689- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2690 since mimetools itself is deprecated. Because modules are cached, all
2691 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2692
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002693- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002695- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2696 menu entries were not deleted.
2697
Brett Cannon83e81842008-08-09 23:30:55 +00002698- Copied the implementation of reduce() to _functools.reduce() to have a
2699 version that did not raise a DeprecationWarning under -3.
2700
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002701- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2702 a MemoryError rather than silently stop the iteration.
2703
Guido van Rossum59ce9012008-08-09 14:55:34 +00002704- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2705 to _sre.compile() will now be rejected. This should not affect anybody
2706 since the re.compile() function never generates invalid re-bytecode.
2707
Skip Montanaroa032bf42008-08-08 22:52:51 +00002708- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2709 upon first access it can be automatically initialized from the csv file if
2710 it wasn't initialized during instantiation.
2711
Brett Cannon3aa2a492008-08-06 22:28:09 +00002712- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2713 the reload() built-in has been removed.
2714
Brett Cannon7e30b672008-08-04 21:52:25 +00002715- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002716 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2724 raised an AttributeError.
2725
Benjamin Peterson01a24322008-07-28 23:35:27 +00002726- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002727 asking for a specific length. This problem only affected files opened
2728 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002729

2752
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002753- Issue #3394: zipfile.writestr sets external attributes when passed a
2754 file name rather than a ZipInfo instance, so files are extracted with
2755 mode 0600 rather than 000 under Unix.
2756
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002757- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2758 argument in python 2.5, this broke code that subclassed Popen to include its

2770 interaction with the tp_hash slot (added in 2.6b2) are now documented
2771
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002772- Issue #643841: The language reference now provides more detailed
2773 coverage of the lookup process for special methods. The disclaimers
2774 regarding lack of coverage of new-style classes have also been
2775 removed, since the coverage is now fairly reasonable.

2779================================
2780
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002781*Release date: 17-Jul-2008*
2782
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002783Core and Builtins
2784-----------------
2785
Georg Brandl3e483f62008-07-16 22:57:41 +00002786- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2787 its methods now allow for items objects that can be converted to
2788 an integer using operator.index().
2789
Mark Dickinson64b7e502008-07-16 09:40:03 +00002790- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2791 produced a ValueError instead of giving the correct float.
2792
Eric Smitha5fa5a22008-07-16 00:11:49 +00002793- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2794 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2795
Mark Dickinson7103aa42008-07-15 19:08:33 +00002796- Issue #3008: the float type has a new instance method 'float.hex'
2797 and a new class method 'float.fromhex' to convert floating-point
2798 numbers to and from hexadecimal strings, respectively.
2799
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002800- Issue #2235: __hash__ is once again inherited by default. To allow
2801 collections.Hashable to remain meaningful in the presence of the
2802 default hash implementation (object.__hash__), it is now possible
2803 to explicit block inheritance of hash by setting __hash__=None at
2804 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2805 level.
2806
Nick Coghlanb028f502008-07-13 14:52:36 +00002807- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2808 the parent module cannot be found while performing an absolute import.
2809 This means that an incorrectly defined __package__ attribute will
2810 now only prevent relative imports in that module rather than causing
2811 all imports from that module to fail.
2812
Nick Coghlan14ff9942008-07-08 14:21:42 +00002813- Issue #2517: Allow unicode messages in Exceptions again by correctly
2814 bypassing the instance dictionary when looking up __unicode__ on
2815 new-style classes.
2816
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002817- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2818 set to a custom object whose write() method happens to install
2819 another file in sys.stdout.
2820
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002821- Issue #3088: Corrected a race condition in classes derived from
2822 threading.local: the first member set by a thread could be saved in
2823 another thread's dictionary.
2824
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002825- Issue #3004: Minor change to slice.indices(): the start and stop
2826 arguments are now treated identically, making the behaviour easier
2827 to describe and understand. For example, slice(None, -10,
2828 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2829 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2830 10, -1).
2831
Georg Brandl278fc502008-07-19 12:46:12 +00002832- Issue #3219: Calling a function with repeated keyword arguments,
2833 f(a=2, a=23), would not cause a syntax error. This was a regression
2834 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002835
Georg Brandl278fc502008-07-19 12:46:12 +00002836- Issue #2862: Make int and float freelist management consistent with
2837 other freelists. Changes their CompactFreeList apis into
2838 ClearFreeList apis and calls them via gc.collect().

2841-------
2842
Thomas Heller57adf222008-08-14 19:10:48 +00002843- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2844 api functions without holding the GIL, which could lead to a fatal
2845 error when they failed.
2846
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002847- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2856 ForkingPickler.register() to resolve conflict with ctypes.
2857
Vinay Sajip51e65192008-07-18 09:01:10 +00002858- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2861 a valid dlerror() message.
2862
Thomas Heller2bad6572008-07-15 17:19:50 +00002863- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2864 incomplete structure was created.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002872- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2873 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002874 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002875 content-length. The problem had been corrected in the 2.4 branch, but never
2876 merged into trunk.
2877

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002891- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2893
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002894- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3283 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003284 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003285
3286 This is controlled by the configure argument ``--with-universal-archs``:
3287
3288 - ``--with-universal-archs=all``: install 4-way universal
3289
3290 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3291
3292 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3293
3294 This option should be used in combination with ``--enable-universalsdk=``.
3295
3296 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003346- Issue #1631171: Re-implement the 'warnings' module in C (the
3347 original Python code has been kept as backup). This will allow for
3348 using the 'warning's machinery in such places as the parser where
3349 use of pure Python code is not possible. Both the ``showarning()``
3350 and ``formatwarning()`` gain an optional 'line' argument which is
3351 not called by default for backwards-compatibility reasons. Setting
3352 ``warnings.showwarning()`` to an implementation that lacks support
3353 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003416- Issue #2550: The approach used by client/server code for obtaining
3417 ports to listen on in network-oriented tests has been refined in an
3418 effort to facilitate running multiple instances of the entire
3419 regression test suite in parallel without issue.
3420 test_support.bind_port() has been fixed such that it will always
3421 return a unique port -- which wasn't always the case with the
3422 previous implementation, especially if socket options had been set
3423 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3424 new implementation of bind_port() will actually raise an exception
3425 if it is passed an AF_INET/SOCK_STREAM socket with either the
3426 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3427 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3428 the socket it's been passed. This currently only applies to
3429 Windows. This option prevents any other sockets from binding to the
3430 host/port we've bound to, thus removing the possibility of the
3431 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3432 when a second SOCK_STREAM socket binds and accepts to a host/port
3433 that's already been bound by another socket. The optional preferred
3434 port parameter to bind_port() has been removed. Under no
3435 circumstances should tests be hard coding ports!
3436
3437 test_support.find_unused_port() has also been introduced, which will
3438 pass a temporary socket object to bind_port() in order to obtain an
3439 unused port. The temporary socket object is then closed and
3440 deleted, and the port is returned. This method should only be used
3441 for obtaining an unused port in order to pass to an external program
3442 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3443 a parameter to a server-oriented class that doesn't give you direct
3444 access to the underlying socket used.
3445
3446 Finally, test_support.HOST has been introduced, which should be used
3447 for the host argument of any relevant socket calls (i.e. bind and
3448 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003449
3450 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003452 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3453 test_asynchat and test_socket_ssl.
3454
Georg Brandl3ee81df2008-05-17 18:14:43 +00003455 It is now possible for multiple instances of the regression test
3456 suite to run in parallel without issue.

Facundo Batistafc2d0102008-02-23 12:01:13 +00003733 issue 215555 for a discussion.
3734
Eric Smitha73fbe72008-02-23 03:09:44 +00003735- Added the future_builtins module, which contains hex() and oct().
3736 These are the PEP 3127 version of these functions, designed to be
3737 compatible with the hex() and oct() builtins from Python 3.0. They
3738 differ slightly in their output formats from the existing, unchanged
3739 Python 2.6 builtins. The expected usage of the future_builtins
3740 module is:
3741 from future_builtins import hex, oct
3742
Eric Smith7ef40bf2008-02-20 23:34:22 +00003743- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3744 exponents for exponents with absolute value < 100. Follows C99
3745 standard. This is a change on Windows, which would use 3 digits.
3746 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3747 so that any alterations it does to the resulting string will be
3748 available in stringlib/formatter.h (for float.__format__).
3749
Eric Smith5a3c1352008-02-19 13:21:56 +00003750- Implemented PEP 3101, Advanced String Formatting. This adds a new
3751 builtin format(); a format() method for str and unicode; a
3752 __format__() method to object, str, unicode, int, long, float, and
3753 datetime; the class string.Formatter; and the C API
3754 PyObject_Format().
3755
Georg Brandl3ee81df2008-05-17 18:14:43 +00003756- Fixed several potential crashes, all caused by specially crafted
3757 __del__ methods exploiting objects in temporarily inconsistent
3758 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003759
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003760- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003761 prevent a possible crash: an Abstract Base Class would try to access
3762 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003763
Georg Brandl3ee81df2008-05-17 18:14:43 +00003764- Fixed repr() and str() of complex numbers with infinity or nan as
3765 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003766
Georg Brandl3ee81df2008-05-17 18:14:43 +00003767- Clear all free lists during a gc.collect() of the highest generation
3768 in order to allow pymalloc to free more arenas. Python may give back
3769 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003770
Georg Brandl3ee81df2008-05-17 18:14:43 +00003771- Issue #2045: Fix an infinite recursion triggered when printing a
3772 subclass of collections.defaultdict, if its default_factory is set
3773 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003774
Christian Heimesf75dbef2008-02-08 00:11:31 +00003775- Fixed a minor memory leak in dictobject.c. The content of the free
3776 list was not freed on interpreter shutdown.
3777
Georg Brandl21e99f42010-03-07 15:23:59 +00003778- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003779 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003780
Georg Brandl3ee81df2008-05-17 18:14:43 +00003781- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3782 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003783 to compact the internal free lists of pre-allocted ints and floats.
3784
Georg Brandl3ee81df2008-05-17 18:14:43 +00003785- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3786 calls. Python expected the return type int but the fork familie
3787 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003788
Georg Brandl3ee81df2008-05-17 18:14:43 +00003789- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3790 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003791
Georg Brandl3ee81df2008-05-17 18:14:43 +00003792- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3793 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003794
Georg Brandl3ee81df2008-05-17 18:14:43 +00003795- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3796 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003797
Georg Brandl3ee81df2008-05-17 18:14:43 +00003798- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3799 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003800
Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- Patch #1473257: generator objects gain a gi_code attribute. This is
3802 the same object as the func_code attribute of the function that
3803 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003804
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- Issue #1920: "while 0" statements were completely removed by the
3806 compiler, even in the presence of an "else" clause, which is
3807 supposed to be run when the condition is false. Now the compiler
3808 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003809
Guido van Rossumeead05f2008-01-24 18:21:02 +00003810- A few crashers fixed: weakref_in_del.py (issue #1377858);
3811 loosing_dict_ref.py (issue #1303614, test67.py);
3812 borrowed_ref_[34].py (not in tracker).
3813
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003814- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003815 suppressed while an extension is loaded by calling SetErrorMode in
3816 dynload_win.c. The error is still reported properly.
3817
Georg Brandl3ee81df2008-05-17 18:14:43 +00003818- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003819 several extension methods and modules do not work without unicode
3820 support.
3821
Georg Brandl26543b12008-01-21 18:36:51 +00003822- Issue #1882: when compiling code from a string, encoding cookies in the
3823 second line of code were not always recognized correctly.
3824
Georg Brandl14404b62008-01-19 19:27:05 +00003825- Issue #1679: "0x" was taken as a valid integer literal.
3826
Georg Brandl6caad7d2008-01-26 14:19:22 +00003827- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003828 added.
3829
Christian Heimesc94e2b52008-01-14 04:13:37 +00003830- sys.float_info / PyFloat_GetInfo: The floating point information
3831 object was converted from a dict to a specialized structseq object.
3832
Georg Brandl3ee81df2008-05-17 18:14:43 +00003833- Patch #1816: Added sys.flags structseq. It exposes the status of
3834 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003835
Georg Brandl3ee81df2008-05-17 18:14:43 +00003836- Objects/structseq.c: Implemented new structseq representation. The
3837 patch makes structseqs (e.g. the return value of os.stat) more
3838 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003839
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840- Patch #1700288: added a type attribute cache that caches method
3841 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003842
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003843- Bug #1776: __import__() no longer accepts filenames on any platform.
3844 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003845
Georg Brandlaed6c662008-01-07 17:25:53 +00003846- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3847
Georg Brandl3ee81df2008-05-17 18:14:43 +00003848- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3849 envvar and sys.dont_write_bytecode attribute. All these can be set
3850 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003851
Georg Brandl3ee81df2008-05-17 18:14:43 +00003852- Improve some exception messages when Windows fails to load an
3853 extension module. Now we get for example '%1 is not a valid Win32
3854 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003855
Georg Brandl3ee81df2008-05-17 18:14:43 +00003856- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3859 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003860
Christian Heimes0a8143f2007-12-18 23:22:54 +00003861- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862 and INF. float("nan"), float("inf") and float("-inf") now work on
3863 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003864
Georg Brandl3ee81df2008-05-17 18:14:43 +00003865- Compiler now generates simpler and faster code for dictionary
3866 literals. The oparg for BUILD_MAP now indicates an estimated
3867 dictionary size. There is a new opcode, STORE_MAP, for adding
3868 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003902- Issue #1265: Fix a problem with sys.settrace, if the tracing
3903 function uses a generator expression when at the same time the
3904 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003905
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003906- sets and frozensets now have an isdisjoint() method.
3907
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003908- optimize the performance of builtin.sum().

3911
Georg Brandl21e99f42010-03-07 15:23:59 +00003912- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003913 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3914 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003915
Georg Brandl3ee81df2008-05-17 18:14:43 +00003916- Issue #1686386: Tuple's tp_repr did not take into account the
3917 possibility of having a self-referential tuple, which is possible
3918 from C code. Nor did object's tp_str consider that a type's tp_str
3919 could do something that could lead to an inifinite recursion.
3920 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3921 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003922
Georg Brandl3ee81df2008-05-17 18:14:43 +00003923- Issue #1164: It was possible to trigger deadlock when using the
3924 'print' statement to write to a file since the GIL was not released
3925 as needed. Now PyObject_Print() does the right thing along with
3926 various tp_print implementations of the built-in types and those in
3927 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003928
Georg Brandl3ee81df2008-05-17 18:14:43 +00003929- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00003936- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003937 PyObject_Call() never calling back out to Python code to trigger
3938 recursion depth updates/checks. Required the creation of a static
3939 RuntimeError instance in case normalizing an exception put the
3940 recursion check value past its limit. Fixes crashers
3941 infinite_rec_(1|2|4|5).py.

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003960- Add -3 option to the interpreter to warn about features that are
3961 deprecated and will be changed/removed in Python 3.0.
3962
Georg Brandl2134e752007-05-21 20:34:16 +00003963- Patch #1686487: you can now pass any mapping after '**' in function
3964 calls.
3965
Collin Winter62903052007-05-18 23:11:24 +00003966- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967 "except E as target:". This is to provide forwards compatibility
3968 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003975- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003976 setting a plain string, ie don't expand to single letter identifiers.

Raymond Hettinger13936692007-04-11 18:40:58 +00003978- Request #1191699: Slices can now be pickled.
3979
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003980- Request #1193128: str.translate() now allows a None argument for
3981 translations that only remove characters without re-mapping the
3982 remaining characters.
3983
Georg Brandl5cb76c12007-03-21 09:00:39 +00003984- Patch #1682205: a TypeError while unpacking an iterable is no longer
3985 masked by a generic one with the message "unpack non-sequence".

3988
Guido van Rossum143b5642007-03-23 04:58:42 +00003989- Bug #1683368: The object.__init__() and object.__new__() methods are
3990 now stricter in rejecting excess arguments. The only time when
3991 either allows excess arguments is when it is not overridden and the
3992 other one is. For backwards compatibility, when both are
3993 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003994 warning later). Also, type.__init__() insists on the same signature
3995 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003996
Georg Brandl3ee81df2008-05-17 18:14:43 +00003997- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3998 object to complex using its __complex__() method before falling back
3999 to the __float__() method. Therefore, the functions in the cmath
4000 module now can operate on objects that define a __complex__()
4001 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004019- Bug #1678647: write a newline after printing an exception in any
4020 case, even when converting the value to a string failed.
4021
Georg Brandl871f1bc2007-03-12 13:17:36 +00004022- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004023 its argument, if it exists. If not, it will work like before. This
4024 allows customizing the output of dir() in the presence of a
4025 __getattr__().

4035 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004036
Georg Brandlaa2321b2007-03-07 00:40:28 +00004037- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004038 makes the filenames the warning module prints much more sensible
4039 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004052- Patch #1674228: when assigning a slice (old-style), check for the
4053 sq_ass_slice instead of the sq_slice slot.
4054
Georg Brandl3ee81df2008-05-17 18:14:43 +00004055- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00004107- Bug #1545497: when given an explicit base, int() did ignore NULs
4108 embedded in the string to convert.
4109
Georg Brandl846f73a2006-10-08 07:11:54 +00004110- Bug #1569998: break inside a try statement (outside a loop) is now

Neal Norwitzdac090d2006-09-05 03:53:08 +00004157- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158 generator expressions (x for x, in ... ) works again. Fixing this
4159 problem required changing the .pyc magic number. This means that
4160 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004590 AttributeError instead of an IOError when the server's response
4591 didn't contain a valid HTTP status line.

4682 TestCase and TestSuite subclasses (not instances) are no longer
4683 accepted in TestSuite.addTest(). This should cause no

4685 -- the failure just occurred later, with a more cumbersome
4686 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004967- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4968 with RFC 3207 and forgets any knowledge obtained from the server not
4969 obtained from the TLS negotiation itself. Patch contributed by Bill
4970 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004971
Georg Brandl3ee81df2008-05-17 18:14:43 +00004972- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004973 that the SMTP.starttls() caller no longer needs to call ehlo()
4974 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004975 does not claim to support starttls. Adds the
4976 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5057 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5058 silently miscode subclasses of those types. Now, it raises a
5059 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005060

Georg Brandl3ee81df2008-05-17 18:14:43 +00005075 time so that opening a database previously created with the DB_DUP
5076 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5077 opens. Specifically: dictionary assignment to a DB object will
5078 replace all values for a given key when the database allows
5079 duplicate values. DB users should use DB.put(k, v) when they want
5080 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005081

5087 characters with ASCII value less than 32. Also, it correctly quotes
5088 dots only if they occur on a single line, as opposed to the previous
5089 behavior of quoting dots if they are the second character of any
5090 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005091

Georg Brandl3ee81df2008-05-17 18:14:43 +00005496- Removed the macfs module. It had been deprecated since Python 2.5.
5497 This lead to the deprecation of macostools.touched() as it relied
5498 solely on macfs and was a no-op under OS X.
