37
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000038- Issue #8233: When run as a script, py_compile.py optionally takes a single
39 argument `-` which tells it to read files to compile from stdin. Each line
40 is read on demand and the named file is compiled immediately. (Original
41 patch by Piotr Ożarowski).

52 a Fractions instance now raise TypeError instead of returning
53 True/False. This makes Fraction <=> complex comparisons consistent with
54 int <=> complex, float <=> complex, and complex <=> complex comparisons.
55
Michael Foorde6410c52010-03-29 20:04:23 +000056- Addition of ``WeakSet`` to the ``weakref`` module.

73 when Python is running in WOW64 mode on 64 bit Windows.
74
Vinay Sajip804899b2010-03-22 15:29:01 +000075- logging: Added getChild utility method to Logger and added isEnabledFor
76 method to LoggerAdapter.
77
Vinay Sajip31e928e2010-03-22 13:02:28 +000078- Issue #8201: logging: Handle situation of non-ASCII and Unicode

Georg Brandlba83f822010-03-14 09:50:54 +0000110 for ``TimedRotatingFileHandler`` by using the modification time of an
111 existing log file to compute the next rollover time. If the log file does
112 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000113

121
Georg Brandlba83f822010-03-14 09:50:54 +0000122- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
123 a base64 transfer-encoded payload *after* decoding it; it no longer does.
124 This is a behavior change, so email's minor version number is now bumped, to
125 version 4.0.2, for the 2.7 release.

Matthias Klose54cc5392010-03-15 12:46:18 +0000135
Matthias Klose817acef2010-03-15 00:02:36 +0000136- Issue #8142: Update libffi to the 3.0.9 release.
137
Georg Brandlba83f822010-03-14 09:50:54 +0000138- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
139 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
140 argument's __int__ method to convert to an integer before packing. It also
141 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
142 was inconsistent: __int__ was used for some integer codes but not for others,
143 and the set of integer codes for which it was used differed between native
144 packing and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000422- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000423 file position when calling `truncate()`. It would previously change the file
424 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000425 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

430 class used to represent files stored inside an archive. The new
431 implementation is significantly faster and can be wrapped in a
432 ``io.BufferedReader`` object for more speedups. It also solves an issue
433 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +0000444- Issue #7748: Since unicode values are supported for some metadata options in

446 encoded string for them. This ensures that the upload and register commands
447 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000516What's New in Python 2.7 alpha 2?
517=================================

521Core and Builtins
522-----------------
523
Georg Brandlba83f822010-03-14 09:50:54 +0000524- The ``__complex__()`` method is now looked up on the class of instances to
525 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000526
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000527- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
528 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
529
Mark Dickinson1b34d252010-01-01 17:27:30 +0000530- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000531 DeprecationWarning when passed a float argument where an integer was expected.
532 These functions and methods now raise TypeError instead. The majority of the
533 effects of this change are in the extension modules, but some core functions
534 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
535 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +0000536

538 AttributeError.
539
Georg Brandlba83f822010-03-14 09:50:54 +0000540- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
541 in ** operator. The behaviour now conforms to that described in C99 Annex F.

Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000544
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000545- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
546 used to drop the time part of the result.
547
Georg Brandlba83f822010-03-14 09:50:54 +0000548- Issue #1811: Improve accuracy and cross-platform consistency for true division
549 of integers: the result of a/b is now correctly rounded for ints a and b (at
550 least on IEEE 754 platforms), and in particular does not depend on the
551 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000552
Georg Brandlba83f822010-03-14 09:50:54 +0000553- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
554 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
555 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000556
Georg Brandlba83f822010-03-14 09:50:54 +0000557- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +0000558 executables on OSX.
559
Georg Brandlba83f822010-03-14 09:50:54 +0000560 These executables now work properly with the arch(1) command: ``arch -ppc
561 python`` will start a universal binary version of python in PPC mode (unlike
562 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000563
Georg Brandlba83f822010-03-14 09:50:54 +0000564- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
565 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +0000566
Benjamin Peterson4895af42009-12-13 16:36:53 +0000567- Issue #7491: Metaclass's __cmp__ method was ignored.

Georg Brandlba83f822010-03-14 09:50:54 +0000576- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
577 allowing for a maximum number of tasks within the pool to be completed by the
578 worker before that worker is terminated, and a new one created to replace it.
Jesse Noller654ade32010-01-27 03:05:57 +0000579

Georg Brandlba83f822010-03-14 09:50:54 +0000585 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
586 alternative to cPickle if you care about performance. Patch by Florent
Antoine Pitrou80157252010-01-08 19:20:17 +0000587 Xicluna.

Ezio Melotti569e61f2009-12-30 06:14:51 +0000606 Initial patch by Brian Curtin.
607
Georg Brandlba83f822010-03-14 09:50:54 +0000608- Distutils now correctly identifies the build architecture as "x86_64" when
609 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +0000610

615 Distutils upload command to avoid an error when PyPI reads it. This occurs on
616 long passwords. Initial patch by JP St. Pierre.
Tarek Ziadé2421d562009-12-20 23:23:34 +0000617
Georg Brandlba83f822010-03-14 09:50:54 +0000618- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000621- Issue #7349: Make methods of file objects in the io module accept None as an
622 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
623 the same as passing no argument.
624
Georg Brandlba83f822010-03-14 09:50:54 +0000625- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
626 argument like other file objects.

Georg Brandlba83f822010-03-14 09:50:54 +0000644- Issue #7767: New function ``PyLong_AsLongLongAndOverflow()`` added, analogous
645 to ``PyLong_AsLongAndOverflow()``.
Mark Dickinsona36507c2010-01-30 10:08:33 +0000646
Georg Brandlba83f822010-03-14 09:50:54 +0000647- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
648 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
649 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
650 float arguments for integer format codes (other than 'L'): previously an
651 attempt to pass a float resulted in a DeprecationWarning; now it gives a
652 TypeError. For the 'L' format code (which previously had no warning) there is
653 now a DeprecationWarning.

Barry Warsaw12582c92008-10-02 03:33:51 +0000689What's New in Python 2.7 alpha 1

Georg Brandlba83f822010-03-14 09:50:54 +0000697- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
698 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000699
Georg Brandlba83f822010-03-14 09:50:54 +0000700- Issue #3382: 'F' formatting for float and complex now convert the result to
701 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
702 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000703
Georg Brandlba83f822010-03-14 09:50:54 +0000704- Remove switch from "%f" formatting to "%g" formatting for floats larger than
705 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000706
Georg Brandlba83f822010-03-14 09:50:54 +0000707- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
708 1e-100 used to raise OverflowError, but now gives the requested 120
709 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000710

Georg Brandlba83f822010-03-14 09:50:54 +0000715- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
716 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000717
Georg Brandlba83f822010-03-14 09:50:54 +0000718- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
719 decimal string that's guaranteed to round back to x under correct rounding
720 (with round-half-to-even rounding mode). Previously it gave a string based on
721 rounding x to 17 decimal digits. repr(x) for a complex number behaves
722 similarly. On platforms where the correctly-rounded strtod and dtoa code is
723 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000724
Georg Brandlba83f822010-03-14 09:50:54 +0000725- Issue #7117: On almost all platforms: float-to-string and string-to-float
726 conversions within Python are now correctly rounded. Places these conversions
727 occur include: str for floats and complex numbers; the float and complex
728 constructors; old-style and new-style numeric formatting; serialization and
729 deserialization of floats and complex numbers using marshal, pickle and json;
730 parsing of float and imaginary literals in Python code; Decimal-to-float
731 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000732
Georg Brandlba83f822010-03-14 09:50:54 +0000733 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
734 providing correctly-rounded strtod and dtoa C functions. This code is
735 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
736 the C compiler. There may be a small number of platforms on which correct
737 operation of this code cannot be guaranteed, so the code is not used: notably,
738 this applies to platforms where the C double format is not IEEE 754 binary64,
739 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
740 and Python's configure script is unable to determine how to change the FPU
741 precision. On these platforms conversions use the platform strtod and dtoa,
742 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000743
Georg Brandlba83f822010-03-14 09:50:54 +0000744- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
745 uses the correctly-rounded string <-> float conversions described above (when
746 available), and so produces correctly rounded results that will display nicely
747 under the float repr. There are two related small changes: (1) round now
748 accepts any class with an ``__index__()`` method for its second argument (but
749 no longer accepts floats for the second argument), and (2) an excessively
750 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
751 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000752
Philip Jenveyfab8be22009-11-17 02:42:26 +0000753- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
754
Georg Brandlba83f822010-03-14 09:50:54 +0000755- Fix several issues with ``compile()``. The input can now contain Windows and
756 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +0000757

1130 this code path is really executed because I cannot move to such directory on

1157 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2533
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002534- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2535 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2536 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2537 ``printf`` function, whereas PyString_FromFormat has an independent
2538 implementation and uses "%zd" on all platforms for size_t values.
2539 This makes a difference on win64, where ``printf`` needs "%Id" to display
2540 64bit values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002559- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002560 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2561 mechanism. In the process, fix a bug where isinstance() and issubclass(),

2563 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2564 type object.

2637 DeprecationWarning related to warnings.warn_explicit().
2638
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002639- The deprecation warnings for the old camelCase threading API were removed.
2640
Vinay Sajip35e3b032008-09-01 14:33:59 +00002641- logging: fixed lack of use of encoding attribute specified on a stream.
2642
Christian Heimesa27a62e2008-08-22 19:55:54 +00002643- Silenced a trivial compiler warning in the sqlite module.
2644
Christian Heimes1cc69632008-08-22 20:10:27 +00002645- Fixed two format strings in the _collections module.
2646
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002647- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
2648 directory.

Gregory P. Smithd7122032008-09-02 05:36:11 +00002650- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
2651 non-integer floating point number.
2652
Vinay Sajip65d66e12008-09-04 07:31:21 +00002653- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

2660 _check_logger_class from multiprocessing.
2661
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002662- Issue #2975: When compiling several extension modules with Visual Studio 2008
2663 from the same python interpreter, some environment variables would grow
2664 without limit.
2665
Benjamin Peterson37346b22008-08-23 20:27:43 +00002666- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2667 exploitation of poor argument checking.
2668
Gerhard Häringef2276b2008-09-12 13:54:06 +00002669- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
2670
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00002671- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
2672 remaining ones have "pysqlite_" prefix.
2673
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002674- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

2682 wrapper for warnings.catch_warnings() that makes it easier to check
2683 that expected warning messages are being reported.
2684

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002703What's New in Python 2.6 beta 3?
2704================================
2705
Barry Warsaw07a4a382008-08-21 01:15:08 +00002706*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002707
2708Core and Builtins
2709-----------------
2710
Guido van Rossumf8402962008-08-20 15:01:50 +00002711- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2712 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2713 extensions do not automatically benefit from the class attribute
2714 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2715 to their tp_flags field if they care. This is a backwards
2716 compatibility feature; in 3.0, all types will use the cache by
2717 default.
2718
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002719- Keyword arguments can now follow starred arguments. (``f(a, *args,
2720 keyword=23)`` is now valid syntax.)
2721
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002722- ctypes function pointers that are COM methods have a boolean True
2723 value again.
2724
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002725- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2726 by denying s# to parse objects that have a releasebuffer procedure,
2727 and introducing s*.
2728
Georg Brandl1e13ea92008-08-11 09:07:59 +00002729- Issue #3537: Fix an assertion failure when an empty but presized dict
2730 object was stored in the freelist.
2731
Mark Dickinsonb6467572008-08-04 21:30:09 +00002732- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2733 ValueError consistently across platforms.
2734
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002735- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2736 (64bit Unix, for example), unichr() would truncate its argument and return
2737 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2738
Neal Norwitze7d8be82008-07-31 17:17:14 +00002739- Apply security patches from Apple.
2740
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002741- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2742 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2743
Antoine Pitrou92f82162008-07-25 22:22:08 +00002744- Issue #1819: function calls with several named parameters are now on
2745 average 35% faster (as measured by pybench).
2746
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002747- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2748 the python debugger steps into a class statement: the free variables (local
2749 variables defined in an outer scope) would be deleted from the outer scope.
2750
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002751- Issue #2620: Overflow checking when allocating or reallocating memory
2752 was not always being done properly in some python types and extension
2753 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2754 all been updated to perform better checks and places in the code that
2755 would previously leak memory on the error path when such an allocation
2756 failed have been fixed.
2757
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002758Library
2759-------
2760
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002761- Issue #3612: Added some missing basic types in ctypes.wintypes.
2762
Benjamin Petersone977ad42008-08-20 01:42:01 +00002763- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2764 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2765
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002766- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2767 version reported by these tools does not necessarily follow the python
2768 version numbering scheme, so the module is less strict when parsing it.
2769
Nick Coghlanf70385a2008-08-18 12:42:46 +00002770- Issue #2235: Added Py3k warnings for types which will become unhashable
2771 under the stricter __hash__ inheritance rules in 3.0. Several types
2772 which did not meet the rules for hash invariants and were already
2773 unhashable in 3.0 have now been explicitly flagged as unhashable in
2774 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2775 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2776
Brett Cannon88f801d2008-08-18 00:46:22 +00002777- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2778 imported into the module but exposed as part of the module's API.
2779

2785
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002786- Issue #3575: Incremental decoder's decode function now takes bytearray
2787 by using 's*' instead of 't#'.
2788
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002789- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002790 fails unicode conversion on 2nd parameter. (windows only)
2791
Facundo Batista94f243a2008-08-17 03:38:39 +00002792- Issue 2464. urllib2 now supports a malformation in the URL received
2793 in a redirect.
2794
Brett Cannonabe423e2008-08-16 21:47:07 +00002795- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002796 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002797
Facundo Batistaeb90b782008-08-16 14:44:07 +00002798- Issue #2776: fixed small issue when handling an URL with double slash
2799 after a 302 response in the case of not going through a proxy.
2800
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002801- Issue #2676: in the email package, content-type parsing was hanging on
2802 pathological input because of quadratic or exponential behaviour of a
2803 regular expression.
2804
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002805- Issue #3476: binary buffered reading through the new "io" library is now
2806 thread-safe.
2807
Brett Cannonbf3157b2008-08-14 05:00:03 +00002808- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2809 since mimetools itself is deprecated. Because modules are cached, all
2810 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2811
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002812- Issue #3134: shutil referenced undefined WindowsError symbol.
2813
Robert Schuppenies14646332008-08-10 11:01:53 +00002814- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2815 menu entries were not deleted.
2816
Brett Cannon83e81842008-08-09 23:30:55 +00002817- Copied the implementation of reduce() to _functools.reduce() to have a
2818 version that did not raise a DeprecationWarning under -3.
2819
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002820- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2821 a MemoryError rather than silently stop the iteration.
2822
Guido van Rossum59ce9012008-08-09 14:55:34 +00002823- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2824 to _sre.compile() will now be rejected. This should not affect anybody
2825 since the re.compile() function never generates invalid re-bytecode.
2826
Skip Montanaroa032bf42008-08-08 22:52:51 +00002827- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2828 upon first access it can be automatically initialized from the csv file if
2829 it wasn't initialized during instantiation.
2830
Brett Cannon3aa2a492008-08-06 22:28:09 +00002831- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2832 the reload() built-in has been removed.
2833
Brett Cannon7e30b672008-08-04 21:52:25 +00002834- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002835 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2843 raised an AttributeError.
2844
Benjamin Peterson01a24322008-07-28 23:35:27 +00002845- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002846 asking for a specific length. This problem only affected files opened
2847 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002848
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002849- Issue #3449: Update decimal module to use most recent specification

2871
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002872- Issue #3394: zipfile.writestr sets external attributes when passed a
2873 file name rather than a ZipInfo instance, so files are extracted with
2874 mode 0600 rather than 000 under Unix.
2875
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002876- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2877 argument in python 2.5, this broke code that subclassed Popen to include its
2878 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2889 interaction with the tp_hash slot (added in 2.6b2) are now documented
2890
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002891- Issue #643841: The language reference now provides more detailed
2892 coverage of the lookup process for special methods. The disclaimers
2893 regarding lack of coverage of new-style classes have also been
2894 removed, since the coverage is now fairly reasonable.

2898================================
2899
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002900*Release date: 17-Jul-2008*
2901
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002902Core and Builtins
2903-----------------
2904
Georg Brandl3e483f62008-07-16 22:57:41 +00002905- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2906 its methods now allow for items objects that can be converted to
2907 an integer using operator.index().
2908
Mark Dickinson64b7e502008-07-16 09:40:03 +00002909- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2910 produced a ValueError instead of giving the correct float.
2911
Eric Smitha5fa5a22008-07-16 00:11:49 +00002912- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2913 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2914
Mark Dickinson7103aa42008-07-15 19:08:33 +00002915- Issue #3008: the float type has a new instance method 'float.hex'
2916 and a new class method 'float.fromhex' to convert floating-point
2917 numbers to and from hexadecimal strings, respectively.
2918
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002919- Issue #2235: __hash__ is once again inherited by default. To allow
2920 collections.Hashable to remain meaningful in the presence of the
2921 default hash implementation (object.__hash__), it is now possible
2922 to explicit block inheritance of hash by setting __hash__=None at
2923 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2924 level.
2925
Nick Coghlanb028f502008-07-13 14:52:36 +00002926- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2927 the parent module cannot be found while performing an absolute import.
2928 This means that an incorrectly defined __package__ attribute will
2929 now only prevent relative imports in that module rather than causing

Georg Brandl5cc774e2008-06-11 20:28:06 +00003403 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003404
3405 This is controlled by the configure argument ``--with-universal-archs``:

3408
3409 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3410
3411 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3412

Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- Issue #1631171: Re-implement the 'warnings' module in C (the
3466 original Python code has been kept as backup). This will allow for
3467 using the 'warning's machinery in such places as the parser where
3468 use of pure Python code is not possible. Both the ``showarning()``
3469 and ``formatwarning()`` gain an optional 'line' argument which is
3470 not called by default for backwards-compatibility reasons. Setting
3471 ``warnings.showwarning()`` to an implementation that lacks support
3472 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Issue #2550: The approach used by client/server code for obtaining
3536 ports to listen on in network-oriented tests has been refined in an
3537 effort to facilitate running multiple instances of the entire
3538 regression test suite in parallel without issue.
3539 test_support.bind_port() has been fixed such that it will always
3540 return a unique port -- which wasn't always the case with the
3541 previous implementation, especially if socket options had been set
3542 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3543 new implementation of bind_port() will actually raise an exception
3544 if it is passed an AF_INET/SOCK_STREAM socket with either the
3545 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3546 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3547 the socket it's been passed. This currently only applies to
3548 Windows. This option prevents any other sockets from binding to the
3549 host/port we've bound to, thus removing the possibility of the
3550 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3551 when a second SOCK_STREAM socket binds and accepts to a host/port
3552 that's already been bound by another socket. The optional preferred
3553 port parameter to bind_port() has been removed. Under no
3554 circumstances should tests be hard coding ports!
3555
3556 test_support.find_unused_port() has also been introduced, which will
3557 pass a temporary socket object to bind_port() in order to obtain an
3558 unused port. The temporary socket object is then closed and
3559 deleted, and the port is returned. This method should only be used
3560 for obtaining an unused port in order to pass to an external program
3561 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3562 a parameter to a server-oriented class that doesn't give you direct
3563 access to the underlying socket used.
3564
3565 Finally, test_support.HOST has been introduced, which should be used
3566 for the host argument of any relevant socket calls (i.e. bind and
3567 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003568
3569 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003570 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003571 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3572 test_asynchat and test_socket_ssl.
3573
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574 It is now possible for multiple instances of the regression test
3575 suite to run in parallel without issue.

3843
Fred Drakea8ee94b2008-03-01 02:45:07 +00003844- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003845 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003847- Issue #2067: file.__exit__() now calls subclasses' close() method.
3848
3849- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003850
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003851- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003852 issue 215555 for a discussion.
3853
Eric Smitha73fbe72008-02-23 03:09:44 +00003854- Added the future_builtins module, which contains hex() and oct().
3855 These are the PEP 3127 version of these functions, designed to be
3856 compatible with the hex() and oct() builtins from Python 3.0. They
3857 differ slightly in their output formats from the existing, unchanged
3858 Python 2.6 builtins. The expected usage of the future_builtins
3859 module is:
3860 from future_builtins import hex, oct
3861
Eric Smith7ef40bf2008-02-20 23:34:22 +00003862- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3863 exponents for exponents with absolute value < 100. Follows C99
3864 standard. This is a change on Windows, which would use 3 digits.
3865 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3866 so that any alterations it does to the resulting string will be
3867 available in stringlib/formatter.h (for float.__format__).
3868
Eric Smith5a3c1352008-02-19 13:21:56 +00003869- Implemented PEP 3101, Advanced String Formatting. This adds a new
3870 builtin format(); a format() method for str and unicode; a
3871 __format__() method to object, str, unicode, int, long, float, and
3872 datetime; the class string.Formatter; and the C API
3873 PyObject_Format().
3874
Georg Brandl3ee81df2008-05-17 18:14:43 +00003875- Fixed several potential crashes, all caused by specially crafted
3876 __del__ methods exploiting objects in temporarily inconsistent
3877 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003878
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003879- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003880 prevent a possible crash: an Abstract Base Class would try to access
3881 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003882

3884 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003885
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886- Clear all free lists during a gc.collect() of the highest generation
3887 in order to allow pymalloc to free more arenas. Python may give back
3888 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003889
Georg Brandl3ee81df2008-05-17 18:14:43 +00003890- Issue #2045: Fix an infinite recursion triggered when printing a
3891 subclass of collections.defaultdict, if its default_factory is set
3892 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003893
Christian Heimesf75dbef2008-02-08 00:11:31 +00003894- Fixed a minor memory leak in dictobject.c. The content of the free
3895 list was not freed on interpreter shutdown.
3896
Georg Brandl21e99f42010-03-07 15:23:59 +00003897- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003898 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003899
Georg Brandl3ee81df2008-05-17 18:14:43 +00003900- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3901 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003902 to compact the internal free lists of pre-allocted ints and floats.
3903
Georg Brandl3ee81df2008-05-17 18:14:43 +00003904- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3905 calls. Python expected the return type int but the fork familie
3906 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003907
Georg Brandl3ee81df2008-05-17 18:14:43 +00003908- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3909 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003910
Georg Brandl3ee81df2008-05-17 18:14:43 +00003911- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3912 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003917- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3918 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003919
Georg Brandl3ee81df2008-05-17 18:14:43 +00003920- Patch #1473257: generator objects gain a gi_code attribute. This is
3921 the same object as the func_code attribute of the function that
3922 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003923
Georg Brandl3ee81df2008-05-17 18:14:43 +00003924- Issue #1920: "while 0" statements were completely removed by the
3925 compiler, even in the presence of an "else" clause, which is
3926 supposed to be run when the condition is false. Now the compiler
3927 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003928
Guido van Rossumeead05f2008-01-24 18:21:02 +00003929- A few crashers fixed: weakref_in_del.py (issue #1377858);
3930 loosing_dict_ref.py (issue #1303614, test67.py);
3931 borrowed_ref_[34].py (not in tracker).
3932
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003933- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003934 suppressed while an extension is loaded by calling SetErrorMode in
3935 dynload_win.c. The error is still reported properly.
3936
Georg Brandl3ee81df2008-05-17 18:14:43 +00003937- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003938 several extension methods and modules do not work without unicode
3939 support.
3940
Georg Brandl26543b12008-01-21 18:36:51 +00003941- Issue #1882: when compiling code from a string, encoding cookies in the
3942 second line of code were not always recognized correctly.
3943
Georg Brandl14404b62008-01-19 19:27:05 +00003944- Issue #1679: "0x" was taken as a valid integer literal.
3945
Georg Brandl6caad7d2008-01-26 14:19:22 +00003946- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003947 added.
3948
Christian Heimesc94e2b52008-01-14 04:13:37 +00003949- sys.float_info / PyFloat_GetInfo: The floating point information
3950 object was converted from a dict to a specialized structseq object.
3951
Georg Brandl3ee81df2008-05-17 18:14:43 +00003952- Patch #1816: Added sys.flags structseq. It exposes the status of
3953 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003954
Georg Brandl3ee81df2008-05-17 18:14:43 +00003955- Objects/structseq.c: Implemented new structseq representation. The
3956 patch makes structseqs (e.g. the return value of os.stat) more
3957 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003958
Georg Brandl3ee81df2008-05-17 18:14:43 +00003959- Patch #1700288: added a type attribute cache that caches method

3968 envvar and sys.dont_write_bytecode attribute. All these can be set
3969 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003970
Georg Brandl3ee81df2008-05-17 18:14:43 +00003971- Improve some exception messages when Windows fails to load an
3972 extension module. Now we get for example '%1 is not a valid Win32
3973 application' instead of 'error code 193'.

3978 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003979
Christian Heimes0a8143f2007-12-18 23:22:54 +00003980- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003981 and INF. float("nan"), float("inf") and float("-inf") now work on
3982 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003983
Georg Brandl3ee81df2008-05-17 18:14:43 +00003984- Compiler now generates simpler and faster code for dictionary
3985 literals. The oparg for BUILD_MAP now indicates an estimated
3986 dictionary size. There is a new opcode, STORE_MAP, for adding
3987 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003988
Georg Brandl3ee81df2008-05-17 18:14:43 +00003989- Issue #1638: %zd configure test fails on Linux.

Georg Brandl21e99f42010-03-07 15:23:59 +00004031- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004032 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4033 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004034
Georg Brandl3ee81df2008-05-17 18:14:43 +00004035- Issue #1686386: Tuple's tp_repr did not take into account the
4036 possibility of having a self-referential tuple, which is possible
4037 from C code. Nor did object's tp_str consider that a type's tp_str
4038 could do something that could lead to an inifinite recursion.
4039 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4040 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004042- Issue #1164: It was possible to trigger deadlock when using the
4043 'print' statement to write to a file since the GIL was not released
4044 as needed. Now PyObject_Print() does the right thing along with
4045 various tp_print implementations of the built-in types and those in
4046 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004056 PyObject_Call() never calling back out to Python code to trigger
4057 recursion depth updates/checks. Required the creation of a static
4058 RuntimeError instance in case normalizing an exception put the
4059 recursion check value past its limit. Fixes crashers

4107
Guido van Rossum143b5642007-03-23 04:58:42 +00004108- Bug #1683368: The object.__init__() and object.__new__() methods are
4109 now stricter in rejecting excess arguments. The only time when
4110 either allows excess arguments is when it is not overridden and the
4111 other one is. For backwards compatibility, when both are
4112 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004113 warning later). Also, type.__init__() insists on the same signature
4114 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004116- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4117 object to complex using its __complex__() method before falling back
4118 to the __float__() method. Therefore, the functions in the cmath
4119 module now can operate on objects that define a __complex__()
4120 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004138- Bug #1678647: write a newline after printing an exception in any
4139 case, even when converting the value to a string failed.
4140
Georg Brandl871f1bc2007-03-12 13:17:36 +00004141- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142 its argument, if it exists. If not, it will work like before. This
4143 allows customizing the output of dir() in the presence of a
4144 __getattr__().

4154 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004155
Georg Brandlaa2321b2007-03-07 00:40:28 +00004156- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004157 makes the filenames the warning module prints much more sensible
4158 when a PYTHONSTARTUP file is used.

4173
Georg Brandl3ee81df2008-05-17 18:14:43 +00004174- When printing an unraisable error, don't print exceptions. before

4742
Georg Brandl92a6bae2007-03-13 17:43:32 +00004743- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004744 are set for invalid interpolation sequences that would lead to

4801 TestCase and TestSuite subclasses (not instances) are no longer
4802 accepted in TestSuite.addTest(). This should cause no

4804 -- the failure just occurred later, with a more cumbersome
4805 exception.

5087 with RFC 3207 and forgets any knowledge obtained from the server not
5088 obtained from the TLS negotiation itself. Patch contributed by Bill
5089 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005090
Georg Brandl3ee81df2008-05-17 18:14:43 +00005091- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005092 that the SMTP.starttls() caller no longer needs to call ehlo()
5093 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005094 does not claim to support starttls. Adds the
5095 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00005179

Georg Brandl3ee81df2008-05-17 18:14:43 +00005194 time so that opening a database previously created with the DB_DUP
5195 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5196 opens. Specifically: dictionary assignment to a DB object will
5197 replace all values for a given key when the database allows
5198 duplicate values. DB users should use DB.put(k, v) when they want
5199 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005200

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005478- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005479 periodic threadstate and signal checking in tight loops. By
5480 default, this option is turned-off. It should only be enabled in
5481 debugged, performance critical applications.

5532-----
5533
Georg Brandl3ee81df2008-05-17 18:14:43 +00005534- Unified naming convention for free lists and their limits. All free
5535 lists in Object/ are named ``free_list``, the counter ``numfree``
5536 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5537 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005538
Georg Brandl3ee81df2008-05-17 18:14:43 +00005539- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5540 to ``PyTuple_SetItem``, it can be used to populate a brand new
5541 frozenset; but it does not steal a reference to the added item.

5553
Georg Brandl3ee81df2008-05-17 18:14:43 +00005554- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5555 of w# format code incorrectly truncated the length to an int, even
5556 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5557 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005558

5579
5580- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5581 outside of pystate.c and should not be necessary.
5582
Georg Brandl3ee81df2008-05-17 18:14:43 +00005583- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5584 absolute imports. In earlier versions they might have used relative
5585 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005586
Georg Brandl3ee81df2008-05-17 18:14:43 +00005587- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5588 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005589
Georg Brandl3ee81df2008-05-17 18:14:43 +00005590- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005615- Removed the macfs module. It had been deprecated since Python 2.5.
5616 This lead to the deprecation of macostools.touched() as it relied
