19 optimizations are disabled when --with-pydebug is used.
20
Victor Stinnerc7790ed2010-03-22 12:36:28 +000021- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000022
Benjamin Peterson96545892010-03-21 20:21:00 +000023- Issue #6474: Make error message from passing an inadequate number of keyword
24 arguments to a function correct.
25
Benjamin Peterson0dee9c12010-03-17 20:41:42 +000026- Issue #8164: Don't allow lambda functions to have a docstring.
27
Victor Stinner66644262010-03-10 22:30:19 +000028- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +000029 (SIGINT). If an error occurs while importing the site module, the error is
30 printed and Python exits. Initialize the GIL before importing the site

Mark Dickinsone096e822010-04-02 10:17:07 +000038- Issue #7279: Comparisons involving a Decimal signaling NaN now
39 signal InvalidOperation instead of returning False. (Comparisons
40 involving a quiet NaN are unchanged.)
41
Mark Dickinson99d80962010-04-02 08:53:22 +000042- Issue #2531: Comparison operations between floats and Decimal
43 instances now return a result based on the numeric values of the
44 operands; previously they returned an arbitrary result based on
45 the relative ordering of id(float) and id(Decimal).
46
Barry Warsawf7f2d6f2010-03-31 21:07:16 +000047- Issue #8233: When run as a script, py_compile.py optionally takes a single
48 argument `-` which tells it to read files to compile from stdin. Each line
49 is read on demand and the named file is compiled immediately. (Original
50 patch by Piotr Ożarowski).
51
52- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
53 like a normal call.

56 form feed (0x0C) are now considered linebreaks, as specified in Unicode
57 Standard Annex #14. See issue #7643.

59
Mark Dickinson9588d992010-03-27 11:14:37 +000060- Comparisons using one of <, <=, >, >= between a complex instance and
61 a Fractions instance now raise TypeError instead of returning
62 True/False. This makes Fraction <=> complex comparisons consistent with
63 int <=> complex, float <=> complex, and complex <=> complex comparisons.
64
Michael Foorde6410c52010-03-29 20:04:23 +000065- Addition of ``WeakSet`` to the ``weakref`` module.
66

75 didn't support chflags() (for example ZFS under FreeBSD). The error is
76 now silenced.
77
Florent Xicluna9e7a4c92010-03-22 16:07:38 +000078- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
79 deprecated.
80
R. David Murrayc9d1a782010-03-22 15:55:09 +000081- Issue #7860: platform.uname now reports the correct 'machine' type
82 when Python is running in WOW64 mode on 64 bit Windows.
83
Vinay Sajip804899b2010-03-22 15:29:01 +000084- logging: Added getChild utility method to Logger and added isEnabledFor
85 method to LoggerAdapter.
86
Vinay Sajip31e928e2010-03-22 13:02:28 +000087- Issue #8201: logging: Handle situation of non-ASCII and Unicode
88 logger names existing at the same time, causing a Unicode error
89 when configuration code attempted to sort the existing loggers.
90
Vinay Sajip3017a7b2010-03-22 12:33:08 +000091- Issue #8200: logging: Handle errors when multiprocessing is not

95 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
96 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +000097
Florent Xiclunacf82fa62010-03-21 12:27:20 +000098- Issue #8179: Fix macpath.realpath() on a non-existing path.

112 the locale.
113
Georg Brandlba83f822010-03-14 09:50:54 +0000114- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000115 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000116 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000117
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000118- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000119 for ``TimedRotatingFileHandler`` by using the modification time of an
120 existing log file to compute the next rollover time. If the log file does
121 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000122

Florent Xicluna47627d52010-03-08 15:20:28 +0000129 classes.
130
Georg Brandlba83f822010-03-14 09:50:54 +0000131- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
132 a base64 transfer-encoded payload *after* decoding it; it no longer does.
133 This is a behavior change, so email's minor version number is now bumped, to
134 version 4.0.2, for the 2.7 release.

Matthias Klose54cc5392010-03-15 12:46:18 +0000144
Matthias Klose817acef2010-03-15 00:02:36 +0000145- Issue #8142: Update libffi to the 3.0.9 release.
146
Georg Brandlba83f822010-03-14 09:50:54 +0000147- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
148 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
149 argument's __int__ method to convert to an integer before packing. It also
150 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
151 was inconsistent: __int__ was used for some integer codes but not for others,
152 and the set of integer codes for which it was used differed between native
153 packing and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000431- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000432 file position when calling `truncate()`. It would previously change the file
433 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000434 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000453- Issue #7748: Since unicode values are supported for some metadata options in
454 Distutils, the DistributionMetadata get_* methods will now return an utf-8
455 encoded string for them. This ensures that the upload and register commands
456 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000525What's New in Python 2.7 alpha 2?

530Core and Builtins
531-----------------
532
Georg Brandlba83f822010-03-14 09:50:54 +0000533- The ``__complex__()`` method is now looked up on the class of instances to
534 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000535
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000536- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
537 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
538
Mark Dickinson1b34d252010-01-01 17:27:30 +0000539- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000540 DeprecationWarning when passed a float argument where an integer was expected.
541 These functions and methods now raise TypeError instead. The majority of the
542 effects of this change are in the extension modules, but some core functions
543 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
544 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +0000545

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000554- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
555 used to drop the time part of the result.
556
Georg Brandlba83f822010-03-14 09:50:54 +0000557- Issue #1811: Improve accuracy and cross-platform consistency for true division
558 of integers: the result of a/b is now correctly rounded for ints a and b (at
559 least on IEEE 754 platforms), and in particular does not depend on the
560 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000561
Georg Brandlba83f822010-03-14 09:50:54 +0000562- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
563 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
564 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000565
Georg Brandlba83f822010-03-14 09:50:54 +0000566- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +0000567 executables on OSX.
568
Georg Brandlba83f822010-03-14 09:50:54 +0000569 These executables now work properly with the arch(1) command: ``arch -ppc
570 python`` will start a universal binary version of python in PPC mode (unlike
571 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000572
Georg Brandlba83f822010-03-14 09:50:54 +0000573- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
574 underlying error when the coercion fails for the left hand operand.

Georg Brandlba83f822010-03-14 09:50:54 +0000585- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
586 allowing for a maximum number of tasks within the pool to be completed by the
587 worker before that worker is terminated, and a new one created to replace it.

Georg Brandlba83f822010-03-14 09:50:54 +0000594 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
595 alternative to cPickle if you care about performance. Patch by Florent

Ezio Melotti569e61f2009-12-30 06:14:51 +0000615 Initial patch by Brian Curtin.
616
Georg Brandlba83f822010-03-14 09:50:54 +0000617- Distutils now correctly identifies the build architecture as "x86_64" when
618 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +0000619

625 long passwords. Initial patch by JP St. Pierre.
Tarek Ziadé2421d562009-12-20 23:23:34 +0000626
Georg Brandlba83f822010-03-14 09:50:54 +0000627- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000630- Issue #7349: Make methods of file objects in the io module accept None as an
631 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
632 the same as passing no argument.
633
Georg Brandlba83f822010-03-14 09:50:54 +0000634- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

654 to ``PyLong_AsLongAndOverflow()``.
Mark Dickinsona36507c2010-01-30 10:08:33 +0000655
Georg Brandlba83f822010-03-14 09:50:54 +0000656- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
657 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
658 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
659 float arguments for integer format codes (other than 'L'): previously an
660 attempt to pass a float resulted in a DeprecationWarning; now it gives a
661 TypeError. For the 'L' format code (which previously had no warning) there is
662 now a DeprecationWarning.

707 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000708
Georg Brandlba83f822010-03-14 09:50:54 +0000709- Issue #3382: 'F' formatting for float and complex now convert the result to
710 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
711 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000712
Georg Brandlba83f822010-03-14 09:50:54 +0000713- Remove switch from "%f" formatting to "%g" formatting for floats larger than
714 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000715
Georg Brandlba83f822010-03-14 09:50:54 +0000716- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
717 1e-100 used to raise OverflowError, but now gives the requested 120
718 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +0000719

725 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000726
Georg Brandlba83f822010-03-14 09:50:54 +0000727- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
728 decimal string that's guaranteed to round back to x under correct rounding
729 (with round-half-to-even rounding mode). Previously it gave a string based on
730 rounding x to 17 decimal digits. repr(x) for a complex number behaves
731 similarly. On platforms where the correctly-rounded strtod and dtoa code is
732 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000733
Georg Brandlba83f822010-03-14 09:50:54 +0000734- Issue #7117: On almost all platforms: float-to-string and string-to-float
735 conversions within Python are now correctly rounded. Places these conversions
736 occur include: str for floats and complex numbers; the float and complex
737 constructors; old-style and new-style numeric formatting; serialization and
738 deserialization of floats and complex numbers using marshal, pickle and json;
739 parsing of float and imaginary literals in Python code; Decimal-to-float
740 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000741
Georg Brandlba83f822010-03-14 09:50:54 +0000742 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
743 providing correctly-rounded strtod and dtoa C functions. This code is
744 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
745 the C compiler. There may be a small number of platforms on which correct
746 operation of this code cannot be guaranteed, so the code is not used: notably,
747 this applies to platforms where the C double format is not IEEE 754 binary64,
748 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
749 and Python's configure script is unable to determine how to change the FPU
750 precision. On these platforms conversions use the platform strtod and dtoa,
751 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000752
Georg Brandlba83f822010-03-14 09:50:54 +0000753- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
754 uses the correctly-rounded string <-> float conversions described above (when
755 available), and so produces correctly rounded results that will display nicely
756 under the float repr. There are two related small changes: (1) round now
757 accepts any class with an ``__index__()`` method for its second argument (but
758 no longer accepts floats for the second argument), and (2) an excessively
759 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
760 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +0000762- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.

1139 this code path is really executed because I cannot move to such directory on

1166 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

2542
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002543- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2544 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2545 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2546 ``printf`` function, whereas PyString_FromFormat has an independent
2547 implementation and uses "%zd" on all platforms for size_t values.
2548 This makes a difference on win64, where ``printf`` needs "%Id" to display
2549 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00002569 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

2572 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2573 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00002643- Issue 3602: Moved test.test_support.catch_warning() to
2644 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2645 for catch_warnings() also led to an improvement in the raising of a
2646 DeprecationWarning related to warnings.warn_explicit().
2647
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002648- The deprecation warnings for the old camelCase threading API were removed.

2670
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002671- Issue #2975: When compiling several extension modules with Visual Studio 2008
2672 from the same python interpreter, some environment variables would grow
2673 without limit.
2674
Benjamin Peterson37346b22008-08-23 20:27:43 +00002675- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2676 exploitation of poor argument checking.
2677
Gerhard Häringef2276b2008-09-12 13:54:06 +00002678- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Gerhard Häring6e1afcf2008-09-12 18:58:57 +00002680- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
2681 remaining ones have "pysqlite_" prefix.
2682
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002683- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002712What's New in Python 2.6 beta 3?
2713================================
2714
Barry Warsaw07a4a382008-08-21 01:15:08 +00002715*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002716
2717Core and Builtins
2718-----------------
2719
Guido van Rossumf8402962008-08-20 15:01:50 +00002720- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2721 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2722 extensions do not automatically benefit from the class attribute
2723 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2724 to their tp_flags field if they care. This is a backwards
2725 compatibility feature; in 3.0, all types will use the cache by
2726 default.
2727
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002728- Keyword arguments can now follow starred arguments. (``f(a, *args,
2729 keyword=23)`` is now valid syntax.)
2730
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002731- ctypes function pointers that are COM methods have a boolean True
2732 value again.
2733
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002734- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2735 by denying s# to parse objects that have a releasebuffer procedure,
2736 and introducing s*.
2737
Georg Brandl1e13ea92008-08-11 09:07:59 +00002738- Issue #3537: Fix an assertion failure when an empty but presized dict
2739 object was stored in the freelist.
2740
Mark Dickinsonb6467572008-08-04 21:30:09 +00002741- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2742 ValueError consistently across platforms.
2743
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002744- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2745 (64bit Unix, for example), unichr() would truncate its argument and return
2746 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2747
Neal Norwitze7d8be82008-07-31 17:17:14 +00002748- Apply security patches from Apple.
2749
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002750- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2751 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2752
Antoine Pitrou92f82162008-07-25 22:22:08 +00002753- Issue #1819: function calls with several named parameters are now on
2754 average 35% faster (as measured by pybench).
2755
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002756- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2757 the python debugger steps into a class statement: the free variables (local
2758 variables defined in an outer scope) would be deleted from the outer scope.
2759
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002760- Issue #2620: Overflow checking when allocating or reallocating memory
2761 was not always being done properly in some python types and extension
2762 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2763 all been updated to perform better checks and places in the code that
2764 would previously leak memory on the error path when such an allocation
2765 failed have been fixed.
2766

2769
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002770- Issue #3612: Added some missing basic types in ctypes.wintypes.
2771
Benjamin Petersone977ad42008-08-20 01:42:01 +00002772- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2773 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2774
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002775- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2776 version reported by these tools does not necessarily follow the python
2777 version numbering scheme, so the module is less strict when parsing it.
2778
Nick Coghlanf70385a2008-08-18 12:42:46 +00002779- Issue #2235: Added Py3k warnings for types which will become unhashable
2780 under the stricter __hash__ inheritance rules in 3.0. Several types
2781 which did not meet the rules for hash invariants and were already
2782 unhashable in 3.0 have now been explicitly flagged as unhashable in
2783 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2784 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2785
Brett Cannon88f801d2008-08-18 00:46:22 +00002786- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2794
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002795- Issue #3575: Incremental decoder's decode function now takes bytearray
2796 by using 's*' instead of 't#'.
2797
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002798- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002799 fails unicode conversion on 2nd parameter. (windows only)
2800
Facundo Batista94f243a2008-08-17 03:38:39 +00002801- Issue 2464. urllib2 now supports a malformation in the URL received
2802 in a redirect.
2803
Brett Cannonabe423e2008-08-16 21:47:07 +00002804- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002805 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002806
Facundo Batistaeb90b782008-08-16 14:44:07 +00002807- Issue #2776: fixed small issue when handling an URL with double slash
2808 after a 302 response in the case of not going through a proxy.
2809
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002810- Issue #2676: in the email package, content-type parsing was hanging on
2811 pathological input because of quadratic or exponential behaviour of a
2812 regular expression.
2813
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002814- Issue #3476: binary buffered reading through the new "io" library is now
2815 thread-safe.
2816
Brett Cannonbf3157b2008-08-14 05:00:03 +00002817- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2818 since mimetools itself is deprecated. Because modules are cached, all
2819 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2820
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002821- Issue #3134: shutil referenced undefined WindowsError symbol.
2822
Robert Schuppenies14646332008-08-10 11:01:53 +00002823- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2824 menu entries were not deleted.
2825
Brett Cannon83e81842008-08-09 23:30:55 +00002826- Copied the implementation of reduce() to _functools.reduce() to have a
2827 version that did not raise a DeprecationWarning under -3.
2828
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002829- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2830 a MemoryError rather than silently stop the iteration.
2831
Guido van Rossum59ce9012008-08-09 14:55:34 +00002832- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2833 to _sre.compile() will now be rejected. This should not affect anybody
2834 since the re.compile() function never generates invalid re-bytecode.
2835
Skip Montanaroa032bf42008-08-08 22:52:51 +00002836- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2837 upon first access it can be automatically initialized from the csv file if
2838 it wasn't initialized during instantiation.
2839
Brett Cannon3aa2a492008-08-06 22:28:09 +00002840- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2841 the reload() built-in has been removed.
2842
Brett Cannon7e30b672008-08-04 21:52:25 +00002843- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002844 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002855 asking for a specific length. This problem only affected files opened
2856 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002857

2883 mode 0600 rather than 000 under Unix.
2884
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002885- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2901 coverage of the lookup process for special methods. The disclaimers
2902 regarding lack of coverage of new-style classes have also been
2903 removed, since the coverage is now fairly reasonable.

2913
Georg Brandl3e483f62008-07-16 22:57:41 +00002914- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2915 its methods now allow for items objects that can be converted to
2916 an integer using operator.index().
2917
Mark Dickinson64b7e502008-07-16 09:40:03 +00002918- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2919 produced a ValueError instead of giving the correct float.
2920
Eric Smitha5fa5a22008-07-16 00:11:49 +00002921- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2922 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2923
Mark Dickinson7103aa42008-07-15 19:08:33 +00002924- Issue #3008: the float type has a new instance method 'float.hex'

2926 numbers to and from hexadecimal strings, respectively.
2927
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002928- Issue #2235: __hash__ is once again inherited by default. To allow
2929 collections.Hashable to remain meaningful in the presence of the
2930 default hash implementation (object.__hash__), it is now possible
2931 to explicit block inheritance of hash by setting __hash__=None at
2932 the Python level, or tp_hash=PyObject_HashNotImplemented at the C

2937 This means that an incorrectly defined __package__ attribute will
2938 now only prevent relative imports in that module rather than causing
2939 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002953- Issue #3004: Minor change to slice.indices(): the start and stop
2954 arguments are now treated identically, making the behaviour easier
2955 to describe and understand. For example, slice(None, -10,
2956 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2957 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2958 10, -1).

3001 both unnecessary (HTTP allows text content to be sent in several forms) and

3461 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003474- Issue #1631171: Re-implement the 'warnings' module in C (the
3475 original Python code has been kept as backup). This will allow for
3476 using the 'warning's machinery in such places as the parser where
3477 use of pure Python code is not possible. Both the ``showarning()``
3478 and ``formatwarning()`` gain an optional 'line' argument which is
3479 not called by default for backwards-compatibility reasons. Setting
3480 ``warnings.showwarning()`` to an implementation that lacks support
3481 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003544- Issue #2550: The approach used by client/server code for obtaining
3545 ports to listen on in network-oriented tests has been refined in an
3546 effort to facilitate running multiple instances of the entire
3547 regression test suite in parallel without issue.
3548 test_support.bind_port() has been fixed such that it will always
3549 return a unique port -- which wasn't always the case with the
3550 previous implementation, especially if socket options had been set
3551 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3552 new implementation of bind_port() will actually raise an exception
3553 if it is passed an AF_INET/SOCK_STREAM socket with either the
3554 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3555 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3556 the socket it's been passed. This currently only applies to
3557 Windows. This option prevents any other sockets from binding to the
3558 host/port we've bound to, thus removing the possibility of the
3559 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3560 when a second SOCK_STREAM socket binds and accepts to a host/port
3561 that's already been bound by another socket. The optional preferred
3562 port parameter to bind_port() has been removed. Under no
3563 circumstances should tests be hard coding ports!
3564
3565 test_support.find_unused_port() has also been introduced, which will
3566 pass a temporary socket object to bind_port() in order to obtain an
3567 unused port. The temporary socket object is then closed and
3568 deleted, and the port is returned. This method should only be used
3569 for obtaining an unused port in order to pass to an external program
3570 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3571 a parameter to a server-oriented class that doesn't give you direct
3572 access to the underlying socket used.
3573
3574 Finally, test_support.HOST has been introduced, which should be used
3575 for the host argument of any relevant socket calls (i.e. bind and
3576 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003577
3578 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003579 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003580 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3581 test_asynchat and test_socket_ssl.
3582
Georg Brandl3ee81df2008-05-17 18:14:43 +00003583 It is now possible for multiple instances of the regression test
3584 suite to run in parallel without issue.

3852
Fred Drakea8ee94b2008-03-01 02:45:07 +00003853- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003854 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003856- Issue #2067: file.__exit__() now calls subclasses' close() method.
3857
3858- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003859
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003860- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003861 issue 215555 for a discussion.
3862
Eric Smitha73fbe72008-02-23 03:09:44 +00003863- Added the future_builtins module, which contains hex() and oct().
3864 These are the PEP 3127 version of these functions, designed to be
3865 compatible with the hex() and oct() builtins from Python 3.0. They
3866 differ slightly in their output formats from the existing, unchanged
3867 Python 2.6 builtins. The expected usage of the future_builtins
3868 module is:
3869 from future_builtins import hex, oct
3870
Eric Smith7ef40bf2008-02-20 23:34:22 +00003871- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3872 exponents for exponents with absolute value < 100. Follows C99
3873 standard. This is a change on Windows, which would use 3 digits.
3874 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3875 so that any alterations it does to the resulting string will be
3876 available in stringlib/formatter.h (for float.__format__).
3877
Eric Smith5a3c1352008-02-19 13:21:56 +00003878- Implemented PEP 3101, Advanced String Formatting. This adds a new
3879 builtin format(); a format() method for str and unicode; a
3880 __format__() method to object, str, unicode, int, long, float, and
3881 datetime; the class string.Formatter; and the C API
3882 PyObject_Format().
3883
Georg Brandl3ee81df2008-05-17 18:14:43 +00003884- Fixed several potential crashes, all caused by specially crafted
3885 __del__ methods exploiting objects in temporarily inconsistent
3886 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003887
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003888- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003889 prevent a possible crash: an Abstract Base Class would try to access
3890 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003891

Georg Brandl3ee81df2008-05-17 18:14:43 +00003895- Clear all free lists during a gc.collect() of the highest generation
3896 in order to allow pymalloc to free more arenas. Python may give back
3897 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003898
Georg Brandl3ee81df2008-05-17 18:14:43 +00003899- Issue #2045: Fix an infinite recursion triggered when printing a
3900 subclass of collections.defaultdict, if its default_factory is set
3901 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003902
Christian Heimesf75dbef2008-02-08 00:11:31 +00003903- Fixed a minor memory leak in dictobject.c. The content of the free
3904 list was not freed on interpreter shutdown.
3905
Georg Brandl21e99f42010-03-07 15:23:59 +00003906- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003907 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003908
Georg Brandl3ee81df2008-05-17 18:14:43 +00003909- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3910 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003911 to compact the internal free lists of pre-allocted ints and floats.
3912
Georg Brandl3ee81df2008-05-17 18:14:43 +00003913- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3914 calls. Python expected the return type int but the fork familie
3915 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003916
Georg Brandl3ee81df2008-05-17 18:14:43 +00003917- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3927 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003928
Georg Brandl3ee81df2008-05-17 18:14:43 +00003929- Patch #1473257: generator objects gain a gi_code attribute. This is
3930 the same object as the func_code attribute of the function that
3931 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003932
Georg Brandl3ee81df2008-05-17 18:14:43 +00003933- Issue #1920: "while 0" statements were completely removed by the
3934 compiler, even in the presence of an "else" clause, which is
3935 supposed to be run when the condition is false. Now the compiler
3936 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003937
Guido van Rossumeead05f2008-01-24 18:21:02 +00003938- A few crashers fixed: weakref_in_del.py (issue #1377858);
3939 loosing_dict_ref.py (issue #1303614, test67.py);
3940 borrowed_ref_[34].py (not in tracker).
3941
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003942- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003943 suppressed while an extension is loaded by calling SetErrorMode in
3944 dynload_win.c. The error is still reported properly.
3945
Georg Brandl3ee81df2008-05-17 18:14:43 +00003946- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003947 several extension methods and modules do not work without unicode
3948 support.
3949
Georg Brandl26543b12008-01-21 18:36:51 +00003950- Issue #1882: when compiling code from a string, encoding cookies in the
3951 second line of code were not always recognized correctly.
3952
Georg Brandl14404b62008-01-19 19:27:05 +00003953- Issue #1679: "0x" was taken as a valid integer literal.
3954
Georg Brandl6caad7d2008-01-26 14:19:22 +00003955- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003956 added.
3957
Christian Heimesc94e2b52008-01-14 04:13:37 +00003958- sys.float_info / PyFloat_GetInfo: The floating point information
3959 object was converted from a dict to a specialized structseq object.
3960
Georg Brandl3ee81df2008-05-17 18:14:43 +00003961- Patch #1816: Added sys.flags structseq. It exposes the status of
3962 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003963
Georg Brandl3ee81df2008-05-17 18:14:43 +00003964- Objects/structseq.c: Implemented new structseq representation. The

3966 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003967
Georg Brandl3ee81df2008-05-17 18:14:43 +00003968- Patch #1700288: added a type attribute cache that caches method

3977 envvar and sys.dont_write_bytecode attribute. All these can be set
3978 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003979
Georg Brandl3ee81df2008-05-17 18:14:43 +00003980- Improve some exception messages when Windows fails to load an
3981 extension module. Now we get for example '%1 is not a valid Win32
3982 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003989- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003990 and INF. float("nan"), float("inf") and float("-inf") now work on
3991 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003992
Georg Brandl3ee81df2008-05-17 18:14:43 +00003993- Compiler now generates simpler and faster code for dictionary
3994 literals. The oparg for BUILD_MAP now indicates an estimated
3995 dictionary size. There is a new opcode, STORE_MAP, for adding
3996 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004025- Patch #1739468: Directories and zipfiles containing a __main__.py
4026 file can now be directly executed by passing their name to the
4027 interpreter. The directory/zipfile is automatically inserted as the
4028 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004030- Issue #1265: Fix a problem with sys.settrace, if the tracing
4031 function uses a generator expression when at the same time the
4032 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004033
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004034- sets and frozensets now have an isdisjoint() method.

4039
Georg Brandl21e99f42010-03-07 15:23:59 +00004040- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004041 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4042 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004043
Georg Brandl3ee81df2008-05-17 18:14:43 +00004044- Issue #1686386: Tuple's tp_repr did not take into account the
4045 possibility of having a self-referential tuple, which is possible
4046 from C code. Nor did object's tp_str consider that a type's tp_str
4047 could do something that could lead to an inifinite recursion.
4048 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4049 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004050
Georg Brandl3ee81df2008-05-17 18:14:43 +00004051- Issue #1164: It was possible to trigger deadlock when using the
4052 'print' statement to write to a file since the GIL was not released
4053 as needed. Now PyObject_Print() does the right thing along with
4054 various tp_print implementations of the built-in types and those in
4055 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004056
Georg Brandl3ee81df2008-05-17 18:14:43 +00004057- Issue #1147: Exceptions were directly allowing string exceptions in
4058 their throw() method even though string exceptions no longer
4059 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Issue #1096: Prevent a segfault from getting the repr of a very
4062 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00004064- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004065 PyObject_Call() never calling back out to Python code to trigger
4066 recursion depth updates/checks. Required the creation of a static
4067 RuntimeError instance in case normalizing an exception put the
4068 recursion check value past its limit. Fixes crashers
4069 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004070

Neal Norwitz0ac60192007-05-27 04:08:54 +00004084- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004085 __*__ attributes. (Some already existed, e.g., __doc__ and
4086 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004087
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004088- Add -3 option to the interpreter to warn about features that are
4089 deprecated and will be changed/removed in Python 3.0.
4090
Georg Brandl2134e752007-05-21 20:34:16 +00004091- Patch #1686487: you can now pass any mapping after '**' in function
4092 calls.
4093
Collin Winter62903052007-05-18 23:11:24 +00004094- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004095 "except E as target:". This is to provide forwards compatibility
4096 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004097
Brett Cannon229cee22007-05-05 01:34:02 +00004098- Deprecate BaseException.message as per PEP 352.
4099
Georg Brandl3ee81df2008-05-17 18:14:43 +00004100- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004101 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004102
Vinay Sajip8549ce32007-05-06 17:53:37 +00004103- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004104 setting a plain string, ie don't expand to single letter identifiers.
4105
Raymond Hettinger13936692007-04-11 18:40:58 +00004106- Request #1191699: Slices can now be pickled.
4107
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004108- Request #1193128: str.translate() now allows a None argument for
4109 translations that only remove characters without re-mapping the
4110 remaining characters.
4111
Georg Brandl5cb76c12007-03-21 09:00:39 +00004112- Patch #1682205: a TypeError while unpacking an iterable is no longer
4113 masked by a generic one with the message "unpack non-sequence".
4114
Neal Norwitzaa754b72007-03-21 06:39:48 +00004115- Remove unused file Python/fmod.c.
4116
Guido van Rossum143b5642007-03-23 04:58:42 +00004117- Bug #1683368: The object.__init__() and object.__new__() methods are
4118 now stricter in rejecting excess arguments. The only time when
4119 either allows excess arguments is when it is not overridden and the
4120 other one is. For backwards compatibility, when both are
4121 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004122 warning later). Also, type.__init__() insists on the same signature
4123 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4126 object to complex using its __complex__() method before falling back
4127 to the __float__() method. Therefore, the functions in the cmath
4128 module now can operate on objects that define a __complex__()
4129 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004130
Georg Brandl3ee81df2008-05-17 18:14:43 +00004131- Patch #1623563: allow __class__ assignment for classes with
4132 __slots__. The old and the new class are still required to have the
4133 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004134

4139 ``object.__reduce_ex__()`` is called with an object that is faking
4140 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004141
Georg Brandl3ee81df2008-05-17 18:14:43 +00004142- Patch #1680015: Don't modify __slots__ tuple if it contains an

4146
Georg Brandl7b9c5552007-03-12 14:30:05 +00004147- Bug #1678647: write a newline after printing an exception in any
4148 case, even when converting the value to a string failed.
4149
Georg Brandl871f1bc2007-03-12 13:17:36 +00004150- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004151 its argument, if it exists. If not, it will work like before. This
4152 allows customizing the output of dir() in the presence of a
4153 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004154
Collin Winter276887b2007-03-12 16:11:39 +00004155- Patch #922167: Python no longer segfaults when faced with infinitely
4156 self-recursive reload() calls (as reported by bug #742342).
4157
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00004161- Patch #1491866: change the complex() constructor to allow
4162 parthensized forms. This means complex(repr(x)) now works instead of
4163 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004164
Georg Brandlaa2321b2007-03-07 00:40:28 +00004165- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004166 makes the filenames the warning module prints much more sensible
4167 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004168

4170 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004171 variable is given, but break into the interactive interpreter just
4172 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00004179
Georg Brandl0fca97a2007-03-05 22:28:08 +00004180- Patch #1674228: when assigning a slice (old-style), check for the
4181 sq_ass_slice instead of the sq_slice slot.
4182
Georg Brandl3ee81df2008-05-17 18:14:43 +00004183- When printing an unraisable error, don't print exceptions. before
4184 the name. This duplicates the behavior whening normally printing
4185 exceptions.

Georg Brandl92a6bae2007-03-13 17:43:32 +00004752- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004753 are set for invalid interpolation sequences that would lead to

4810 TestCase and TestSuite subclasses (not instances) are no longer
4811 accepted in TestSuite.addTest(). This should cause no

4813 -- the failure just occurred later, with a more cumbersome
4814 exception.

5097 obtained from the TLS negotiation itself. Patch contributed by Bill
5098 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005099
Georg Brandl3ee81df2008-05-17 18:14:43 +00005100- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005101 that the SMTP.starttls() caller no longer needs to call ehlo()
5102 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005103 does not claim to support starttls. Adds the
5104 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00005188

Georg Brandl3ee81df2008-05-17 18:14:43 +00005203 time so that opening a database previously created with the DB_DUP
5204 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5205 opens. Specifically: dictionary assignment to a DB object will
5206 replace all values for a given key when the database allows
5207 duplicate values. DB users should use DB.put(k, v) when they want
5208 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005209

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005487- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005488 periodic threadstate and signal checking in tight loops. By
5489 default, this option is turned-off. It should only be enabled in
5490 debugged, performance critical applications.

5542
Georg Brandl3ee81df2008-05-17 18:14:43 +00005543- Unified naming convention for free lists and their limits. All free
5544 lists in Object/ are named ``free_list``, the counter ``numfree``
5545 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5546 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005547
Georg Brandl3ee81df2008-05-17 18:14:43 +00005548- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5549 to ``PyTuple_SetItem``, it can be used to populate a brand new
5550 frozenset; but it does not steal a reference to the added item.

5562
Georg Brandl3ee81df2008-05-17 18:14:43 +00005563- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5564 of w# format code incorrectly truncated the length to an int, even
5565 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5566 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005567

5588
5589- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5590 outside of pystate.c and should not be necessary.
5591
Georg Brandl3ee81df2008-05-17 18:14:43 +00005592- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5593 absolute imports. In earlier versions they might have used relative
5594 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005595
Georg Brandl3ee81df2008-05-17 18:14:43 +00005596- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5597 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005598
Georg Brandl3ee81df2008-05-17 18:14:43 +00005599- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005624- Removed the macfs module. It had been deprecated since Python 2.5.
5625 This lead to the deprecation of macostools.touched() as it relied
