9Core and Builtins
10-----------------
11
Mark Dickinsondbbed042011-09-19 16:38:08 +010012- Issue #12973: Fix overflow checks that invoked undefined behaviour in
13 int.__pow__. These overflow checks were causing int.__pow__ to produce
14 incorrect results with recent versions of Clang, as a result of the
Mark Dickinson4ac5d2c2011-09-19 19:23:55 +010015 compiler optimizing the check away. Also fix similar overflow check
16 in list_repeat (which caused test_list to fail with recent versions
17 of Clang).
Mark Dickinsondbbed042011-09-19 16:38:08 +010018

Antoine Pitrou16166452011-07-12 22:04:20 +020028- Issue #12149: Update the method cache after a type's dictionnary gets
29 cleared by the garbage collector. This fixes a segfault when an instance
30 and its type get caught in a reference cycle, and the instance's
31 deallocator calls one of the methods on the type (e.g. when subclassing
32 IOBase). Diagnosis and patch by Davide Rizzo.
33
Victor Stinnerba8b3a22011-07-08 02:07:45 +020034- Issue #12501: Adjust callable() warning: callable() is only not supported in
35 Python 3.1. callable() is again supported in Python 3.2.
36
Victor Stinner59729ff2011-07-05 11:28:19 +020037- Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and
38 os.write() clamp the length to INT_MAX on Windows.
39
Victor Stinnerd3c7e172011-05-30 23:49:13 +020040- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +020041 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
42 raw_input() interrupted by CTRL+c.
43
Barry Warsawc5643282011-07-19 17:06:30 -040044- dict_proxy objects now display their contents rather than just the class
45 name.

152
Ned Deily87e82bb2011-06-28 19:52:59 -0700153- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
154 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
155 interpreter process. This could cause failures in non-Distutils subprocesses
156 and was unreliable since tests or user programs could modify the interpreter
157 environment after Distutils set it. Instead, have Distutils set the the
158 deployment target only in the environment of each build subprocess. It is
159 still possible to globally override the default by setting
160 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
161 greater or equal to the default value, the value with which the interpreter
162 was built.

168 Kitada.
169
R David Murrayf1138bb2011-06-17 22:23:04 -0400170- Issue #11700: mailbox proxy object close methods can now be called multiple
171 times without error, and _ProxyFile now closes the wrapped file.
172
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200173- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
174 connection if its getresponse() method fails with a socket error. Patch
175 written by Ezio Melotti.
176
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500177- Issue #9284: Allow inspect.findsource() to find the source of doctest
178 functions.
179

189
Barry Warsawc5643282011-07-19 17:06:30 -0400190- sys.setcheckinterval() now updates the current ticker count as well as
191 updating the check interval, so if the user decreases the check interval,
192 the ticker doesn't have to wind down to zero from the old starting point
193 before the new interval takes effect. And if the user increases the
194 interval, it makes sure the new limit takes effect right away rather have an
195 early task switch before recognizing the new interval.

Victor Stinner776e69b2011-06-01 01:03:00 +0200197- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

611 accepted by ``time.mktime`` and ``time.strftime`` is still system
612 dependent, but ``time.mktime`` will now accept full range supported
613 by the OS. Conversion of 2-digit years to 4-digit is deprecated.

1068 This prevents user-created self-referencing ordered dictionaries from
1069 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001531- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1532 start byte and the continuation byte(s) are now considered invalid, instead
1533 of the number of bytes specified by the start byte.
1534 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1535 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1536 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1537 Previous versions returned a single u'\ufffd'.

1541 arises from the "Overriding __eq__ blocks inheritance ..." warning
1542 when turned into an exception: in this case the exception simply
1543 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001545- Issue #8748: Fix two issues with comparisons between complex and integer
1546 objects. (1) The comparison could incorrectly return True in some cases
1547 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1548 (2) The comparison raised an OverflowError for large integers, leading
1549 to unpredictable exceptions when combining integers and complex objects
1550 in sets or dicts.
1551
Mark Dickinson81336372010-05-30 12:12:25 +00001552- Issue #5211: Implicit coercion for the complex type is now completely

1554 alpha 4, but coercion for rich comparisons was accidentally left in.)

1920 changed.

1933 with a non-empty format string. This is an effort to future-proof user
1934 code. If a derived class does not currently implement __format__ but later
1935 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001936 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001937 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001987- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1988 InvalidOperation instead of returning False. (Comparisons involving a quiet
1989 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1990 signaling NaNs remain unhashable.

1993 return a result based on the numeric values of the operands; previously they
1994 returned an arbitrary result based on the relative ordering of id(float) and
1995 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001997- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001998 argument `-` which tells it to read files to compile from stdin. Each line is
1999 read on demand and the named file is compiled immediately. (Original patch by
2000 Piotr Ożarowski).

2010 Fractions instance now raise TypeError instead of returning True/False. This
2011 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2012 <=> complex, and complex <=> complex comparisons.

2112 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002116- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2117 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00002119 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2120 inconsistent: __int__ was used for some integer codes but not for others, and
2121 the set of integer codes for which it was used differed between native packing
2122 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002449- Issue #7748: Since unicode values are supported for some metadata options in
2450 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2451 encoded string for them. This ensures that the upload and register commands
2452 send the correct values to PyPI without any error.

2527-----------------
2528
Georg Brandlba83f822010-03-14 09:50:54 +00002529- The ``__complex__()`` method is now looked up on the class of instances to
2530 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002532- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2533 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2534
Mark Dickinson1b34d252010-01-01 17:27:30 +00002535- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002536 DeprecationWarning when passed a float argument where an integer was expected.
2537 These functions and methods now raise TypeError instead. The majority of the
2538 effects of this change are in the extension modules, but some core functions
2539 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2540 and many unicode/str methods.

2551 used to drop the time part of the result.
2552
Georg Brandlba83f822010-03-14 09:50:54 +00002553- Issue #1811: Improve accuracy and cross-platform consistency for true division
2554 of integers: the result of a/b is now correctly rounded for ints a and b (at
2555 least on IEEE 754 platforms), and in particular does not depend on the
2556 internal representation of a long.

2564
Georg Brandlba83f822010-03-14 09:50:54 +00002565 These executables now work properly with the arch(1) command: ``arch -ppc
2566 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00002702- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
2703 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002704
Georg Brandlba83f822010-03-14 09:50:54 +00002705- Issue #3382: 'F' formatting for float and complex now convert the result to
2706 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
2707 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002708
Georg Brandlba83f822010-03-14 09:50:54 +00002709- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2710 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002711
Georg Brandlba83f822010-03-14 09:50:54 +00002712- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2713 1e-100 used to raise OverflowError, but now gives the requested 120
2714 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00002715
Georg Brandlba83f822010-03-14 09:50:54 +00002716- Add Py3k warnings for parameter names in parentheses.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00002717
Georg Brandlba83f822010-03-14 09:50:54 +00002718- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00002719
Georg Brandlba83f822010-03-14 09:50:54 +00002720- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
2721 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002722
Georg Brandlba83f822010-03-14 09:50:54 +00002723- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2724 decimal string that's guaranteed to round back to x under correct rounding
2725 (with round-half-to-even rounding mode). Previously it gave a string based on
2726 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2727 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2728 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002729
Georg Brandlba83f822010-03-14 09:50:54 +00002730- Issue #7117: On almost all platforms: float-to-string and string-to-float
2731 conversions within Python are now correctly rounded. Places these conversions
2732 occur include: str for floats and complex numbers; the float and complex
2733 constructors; old-style and new-style numeric formatting; serialization and
2734 deserialization of floats and complex numbers using marshal, pickle and json;
2735 parsing of float and imaginary literals in Python code; Decimal-to-float
2736 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002737
Georg Brandlba83f822010-03-14 09:50:54 +00002738 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2739 providing correctly-rounded strtod and dtoa C functions. This code is
2740 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2741 the C compiler. There may be a small number of platforms on which correct
2742 operation of this code cannot be guaranteed, so the code is not used: notably,
2743 this applies to platforms where the C double format is not IEEE 754 binary64,
2744 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2745 and Python's configure script is unable to determine how to change the FPU
2746 precision. On these platforms conversions use the platform strtod and dtoa,
2747 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002748
Georg Brandlba83f822010-03-14 09:50:54 +00002749- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2750 uses the correctly-rounded string <-> float conversions described above (when
2751 available), and so produces correctly rounded results that will display nicely
2752 under the float repr. There are two related small changes: (1) round now
2753 accepts any class with an ``__index__()`` method for its second argument (but
2754 no longer accepts floats for the second argument), and (2) an excessively
2755 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2756 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00002757
Philip Jenveyfab8be22009-11-17 02:42:26 +00002758- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
2759
Georg Brandlba83f822010-03-14 09:50:54 +00002760- Fix several issues with ``compile()``. The input can now contain Windows and
2761 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00002762
Georg Brandlba83f822010-03-14 09:50:54 +00002763- Remove length limitation when constructing a complex number from a unicode
2764 string.

2782 module is the only object holding a reference to it.
Benjamin Peterson196b0922009-10-15 15:44:46 +00002783
Georg Brandlba83f822010-03-14 09:50:54 +00002784- Issue #1754094: Improve the stack depth calculation in the compiler. There
2785 should be no other effect than a small decrease in memory use. Patch by
2786 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00002787
Georg Brandlba83f822010-03-14 09:50:54 +00002788- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
2789 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +00002790
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00002791- Issue #1571184: The Unicode database contains properties for more characters.
2792 The tables for code points representing numeric values, white spaces or line
2793 breaks are now generated from the official Unicode Character Database files,
2794 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00002903- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2904 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2905 but with at least one decimal point and with a default precision
2906 of 12. Previously, the behavior the same but with a default precision of 6.
2907 This more closely matches ``str()``, and reduces surprises when adding
2908 alignment flags to the empty presentation type. This also affects the new
2909 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00002974 untrackable objects are not tracked by the garbage collector. This can reduce
2975 the size of collections and therefore the garbage collection overhead on
2976 long-running programs, depending on their particular use of datatypes.

2983 internal representation of integers, for performance reasons. Base 2**30 is
2984 enabled by default on 64-bit machines. Add --enable-big-digits option to
2985 configure, which overrides the default. Add sys.long_info structseq to

3017
Georg Brandl29c6a282009-04-05 20:23:13 +00003018- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00003019 were suppressing all exceptions. These include list(), filter(), map(),

3021
Benjamin Peterson596d3062009-01-19 15:42:23 +00003022- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00003049- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3050 existing .py counterpart, override the co_filename attributes of all code
3051 objects if the original filename is obsolete (which can happen if the file has
3052 been renamed, moved, or if it is accessed through different paths). Patch by

3106
Georg Brandlba83f822010-03-14 09:50:54 +00003107- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3108 file objects with closefd=False. The file descriptor is still kept open but
3109 the file object behaves like a closed file. The ``FileIO`` object also got a

3135 this code path is really executed because I cannot move to such directory on

4542 ``printf`` function, whereas PyString_FromFormat has an independent
4543 implementation and uses "%zd" on all platforms for size_t values.
4544 This makes a difference on win64, where ``printf`` needs "%Id" to display
4545 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004547- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4548 error.
4549
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004550- Issue #3777: long() applied to a float object now always return a long
4551 object; previously an int would be returned for small values. the __long__
4552 method is allowed to return either an int or a long, but the behaviour of
4553 float objects should not change to respect backward compatibility.
4554
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004555- Issue #3751: str.rpartition would perform a left-partition when called with
4556 a unicode argument.
4557
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004558- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004560- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004561 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004562 was correctly parsed but parsing of subsequent arguments failed.
4563
Vinay Sajip35e3b032008-09-01 14:33:59 +00004564- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004565 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4566 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4567 when given a tuple of classes as second argument, were looking up
4568 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4569 type object.
4570
Neal Norwitz18aa3882008-08-24 05:04:52 +00004571- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004640 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4641 for catch_warnings() also led to an improvement in the raising of a
4642 DeprecationWarning related to warnings.warn_explicit().
4643

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004708What's New in Python 2.6 beta 3?
4709================================
4710
Barry Warsaw07a4a382008-08-21 01:15:08 +00004711*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004712
4713Core and Builtins
4714-----------------
4715
Guido van Rossumf8402962008-08-20 15:01:50 +00004716- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4717 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4718 extensions do not automatically benefit from the class attribute
4719 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4720 to their tp_flags field if they care. This is a backwards
4721 compatibility feature; in 3.0, all types will use the cache by
4722 default.
4723
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004724- Keyword arguments can now follow starred arguments. (``f(a, *args,
4725 keyword=23)`` is now valid syntax.)
4726
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004727- ctypes function pointers that are COM methods have a boolean True
4728 value again.
4729
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004730- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4731 by denying s# to parse objects that have a releasebuffer procedure,
4732 and introducing s*.
4733
Georg Brandl1e13ea92008-08-11 09:07:59 +00004734- Issue #3537: Fix an assertion failure when an empty but presized dict
4735 object was stored in the freelist.
4736
Mark Dickinsonb6467572008-08-04 21:30:09 +00004737- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4738 ValueError consistently across platforms.
4739
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004740- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4741 (64bit Unix, for example), unichr() would truncate its argument and return
4742 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4743
Neal Norwitze7d8be82008-07-31 17:17:14 +00004744- Apply security patches from Apple.
4745
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004746- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4747 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4748
Antoine Pitrou92f82162008-07-25 22:22:08 +00004749- Issue #1819: function calls with several named parameters are now on
4750 average 35% faster (as measured by pybench).
4751
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004752- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4753 the python debugger steps into a class statement: the free variables (local
4754 variables defined in an outer scope) would be deleted from the outer scope.
4755
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004756- Issue #2620: Overflow checking when allocating or reallocating memory
4757 was not always being done properly in some python types and extension
4758 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4759 all been updated to perform better checks and places in the code that
4760 would previously leak memory on the error path when such an allocation
4761 failed have been fixed.

4765
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004766- Issue #3612: Added some missing basic types in ctypes.wintypes.
4767
Benjamin Petersone977ad42008-08-20 01:42:01 +00004768- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4769 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4770
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004771- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4772 version reported by these tools does not necessarily follow the python
4773 version numbering scheme, so the module is less strict when parsing it.
4774
Nick Coghlanf70385a2008-08-18 12:42:46 +00004775- Issue #2235: Added Py3k warnings for types which will become unhashable
4776 under the stricter __hash__ inheritance rules in 3.0. Several types
4777 which did not meet the rules for hash invariants and were already
4778 unhashable in 3.0 have now been explicitly flagged as unhashable in
4779 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4780 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4781
Brett Cannon88f801d2008-08-18 00:46:22 +00004782- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4783 imported into the module but exposed as part of the module's API.
4784
Brett Cannon7b96f072008-08-18 00:41:11 +00004785- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4786
Brett Cannon46225e72008-08-18 00:36:52 +00004787- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

4790
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004791- Issue #3575: Incremental decoder's decode function now takes bytearray
4792 by using 's*' instead of 't#'.
4793
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004794- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004795 fails unicode conversion on 2nd parameter. (windows only)
4796
Georg Brandl222e2082010-08-01 22:27:39 +00004797- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004798 in a redirect.
4799

Brett Cannon721b1452008-08-16 22:00:27 +00004801 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004802
Facundo Batistaeb90b782008-08-16 14:44:07 +00004803- Issue #2776: fixed small issue when handling an URL with double slash
4804 after a 302 response in the case of not going through a proxy.
4805
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004806- Issue #2676: in the email package, content-type parsing was hanging on
4807 pathological input because of quadratic or exponential behaviour of a
4808 regular expression.
4809
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004810- Issue #3476: binary buffered reading through the new "io" library is now
4811 thread-safe.
4812
Brett Cannonbf3157b2008-08-14 05:00:03 +00004813- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4814 since mimetools itself is deprecated. Because modules are cached, all
4815 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4816
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004817- Issue #3134: shutil referenced undefined WindowsError symbol.
4818
Robert Schuppenies14646332008-08-10 11:01:53 +00004819- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4820 menu entries were not deleted.
4821
Brett Cannon83e81842008-08-09 23:30:55 +00004822- Copied the implementation of reduce() to _functools.reduce() to have a
4823 version that did not raise a DeprecationWarning under -3.
4824
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004825- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4826 a MemoryError rather than silently stop the iteration.

Guido van Rossum59ce9012008-08-09 14:55:34 +00004828- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4829 to _sre.compile() will now be rejected. This should not affect anybody

Antoine Pitroude781a42008-08-09 12:43:23 +00004851 asking for a specific length. This problem only affected files opened

4908-----------------
4909
Georg Brandl3e483f62008-07-16 22:57:41 +00004910- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4911 its methods now allow for items objects that can be converted to
4912 an integer using operator.index().
4913
Mark Dickinson64b7e502008-07-16 09:40:03 +00004914- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4915 produced a ValueError instead of giving the correct float.
4916
Eric Smitha5fa5a22008-07-16 00:11:49 +00004917- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4918 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4919
Mark Dickinson7103aa42008-07-15 19:08:33 +00004920- Issue #3008: the float type has a new instance method 'float.hex'
4921 and a new class method 'float.fromhex' to convert floating-point
4922 numbers to and from hexadecimal strings, respectively.
4923
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004924- Issue #2235: __hash__ is once again inherited by default. To allow
4925 collections.Hashable to remain meaningful in the presence of the
4926 default hash implementation (object.__hash__), it is now possible
4927 to explicit block inheritance of hash by setting __hash__=None at
4928 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4929 level.
4930
Nick Coghlanb028f502008-07-13 14:52:36 +00004931- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4932 the parent module cannot be found while performing an absolute import.
4933 This means that an incorrectly defined __package__ attribute will
4934 now only prevent relative imports in that module rather than causing
4935 all imports from that module to fail.
4936
Nick Coghlan14ff9942008-07-08 14:21:42 +00004937- Issue #2517: Allow unicode messages in Exceptions again by correctly

4947 another thread's dictionary.
4948
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004949- Issue #3004: Minor change to slice.indices(): the start and stop
4950 arguments are now treated identically, making the behaviour easier
4951 to describe and understand. For example, slice(None, -10,
4952 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4953 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4954 10, -1).
4955
Georg Brandl278fc502008-07-19 12:46:12 +00004956- Issue #3219: Calling a function with repeated keyword arguments,
4957 f(a=2, a=23), would not cause a syntax error. This was a regression
4958 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00004960- Issue #2862: Make int and float freelist management consistent with
4961 other freelists. Changes their CompactFreeList apis into

4968 api functions without holding the GIL, which could lead to a fatal
4969 error when they failed.
4970
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004971- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004996- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4997 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004998 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004999 content-length. The problem had been corrected in the 2.4 branch, but never
5000 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005015- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5403
Brett Cannonb61d8012008-05-11 23:39:04 +00005404- ``Lib/lib-old`` is now added to sys.path.
5405
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005406- On MacOS X it is now possible to install the framework in 64-bit
5407 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005408 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005409
5410 This is controlled by the configure argument ``--with-universal-archs``:
5411
5412 - ``--with-universal-archs=all``: install 4-way universal
5413
5414 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5415
5416 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5417
5418 This option should be used in combination with ``--enable-universalsdk=``.
5419
5420 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00005429
5430- The PyString functions have been renamed to PyBytes. A batch of
5431 defines were added so that the linker still sees the original
5432 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005470- Issue #1631171: Re-implement the 'warnings' module in C (the
5471 original Python code has been kept as backup). This will allow for
5472 using the 'warning's machinery in such places as the parser where
5473 use of pure Python code is not possible. Both the ``showarning()``
5474 and ``formatwarning()`` gain an optional 'line' argument which is
5475 not called by default for backwards-compatibility reasons. Setting
5476 ``warnings.showwarning()`` to an implementation that lacks support
5477 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005502- The getpass module has been improved on Unix. It now uses /dev/tty
5503 by default and uses stderr instead of stdout. A GetPassWarning is
5504 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005519- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005520 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005540- Issue #2550: The approach used by client/server code for obtaining
5541 ports to listen on in network-oriented tests has been refined in an
5542 effort to facilitate running multiple instances of the entire
5543 regression test suite in parallel without issue.
5544 test_support.bind_port() has been fixed such that it will always
5545 return a unique port -- which wasn't always the case with the
5546 previous implementation, especially if socket options had been set
5547 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5548 new implementation of bind_port() will actually raise an exception
5549 if it is passed an AF_INET/SOCK_STREAM socket with either the
5550 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5551 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5552 the socket it's been passed. This currently only applies to
5553 Windows. This option prevents any other sockets from binding to the
5554 host/port we've bound to, thus removing the possibility of the
5555 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5556 when a second SOCK_STREAM socket binds and accepts to a host/port
5557 that's already been bound by another socket. The optional preferred
5558 port parameter to bind_port() has been removed. Under no
5559 circumstances should tests be hard coding ports!
5560
5561 test_support.find_unused_port() has also been introduced, which will
5562 pass a temporary socket object to bind_port() in order to obtain an
5563 unused port. The temporary socket object is then closed and
5564 deleted, and the port is returned. This method should only be used
5565 for obtaining an unused port in order to pass to an external program
5566 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5567 a parameter to a server-oriented class that doesn't give you direct
5568 access to the underlying socket used.
5569
5570 Finally, test_support.HOST has been introduced, which should be used
5571 for the host argument of any relevant socket calls (i.e. bind and
5572 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005573
5574 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005575 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005576 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5577 test_asynchat and test_socket_ssl.
5578
Georg Brandl3ee81df2008-05-17 18:14:43 +00005579 It is now possible for multiple instances of the regression test
5580 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005859- Added the future_builtins module, which contains hex() and oct().
5860 These are the PEP 3127 version of these functions, designed to be
5861 compatible with the hex() and oct() builtins from Python 3.0. They
5862 differ slightly in their output formats from the existing, unchanged
5863 Python 2.6 builtins. The expected usage of the future_builtins
5864 module is:
5865 from future_builtins import hex, oct
5866
Eric Smith7ef40bf2008-02-20 23:34:22 +00005867- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5868 exponents for exponents with absolute value < 100. Follows C99
5869 standard. This is a change on Windows, which would use 3 digits.
5870 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5871 so that any alterations it does to the resulting string will be
5872 available in stringlib/formatter.h (for float.__format__).
5873
Eric Smith5a3c1352008-02-19 13:21:56 +00005874- Implemented PEP 3101, Advanced String Formatting. This adds a new
5875 builtin format(); a format() method for str and unicode; a
5876 __format__() method to object, str, unicode, int, long, float, and
5877 datetime; the class string.Formatter; and the C API
5878 PyObject_Format().
5879
Georg Brandl3ee81df2008-05-17 18:14:43 +00005880- Fixed several potential crashes, all caused by specially crafted
5881 __del__ methods exploiting objects in temporarily inconsistent
5882 state.

5893 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005894
Georg Brandl3ee81df2008-05-17 18:14:43 +00005895- Issue #2045: Fix an infinite recursion triggered when printing a
5896 subclass of collections.defaultdict, if its default_factory is set
5897 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005898
Christian Heimesf75dbef2008-02-08 00:11:31 +00005899- Fixed a minor memory leak in dictobject.c. The content of the free
5900 list was not freed on interpreter shutdown.
5901
Georg Brandl21e99f42010-03-07 15:23:59 +00005902- Limit free list of method and built-in function objects to 256

5906 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005907 to compact the internal free lists of pre-allocted ints and floats.
5908
Georg Brandl3ee81df2008-05-17 18:14:43 +00005909- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5910 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00005922- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
5923 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005924
Georg Brandl3ee81df2008-05-17 18:14:43 +00005925- Patch #1473257: generator objects gain a gi_code attribute. This is
5926 the same object as the func_code attribute of the function that
5927 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005928
Georg Brandl3ee81df2008-05-17 18:14:43 +00005929- Issue #1920: "while 0" statements were completely removed by the
5930 compiler, even in the presence of an "else" clause, which is
5931 supposed to be run when the condition is false. Now the compiler
5932 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005933
Guido van Rossumeead05f2008-01-24 18:21:02 +00005934- A few crashers fixed: weakref_in_del.py (issue #1377858);
5935 loosing_dict_ref.py (issue #1303614, test67.py);
5936 borrowed_ref_[34].py (not in tracker).
5937
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005938- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005939 suppressed while an extension is loaded by calling SetErrorMode in
5940 dynload_win.c. The error is still reported properly.
5941
Georg Brandl3ee81df2008-05-17 18:14:43 +00005942- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005943 several extension methods and modules do not work without unicode
5944 support.
5945
Georg Brandl26543b12008-01-21 18:36:51 +00005946- Issue #1882: when compiling code from a string, encoding cookies in the

5950
Georg Brandl6caad7d2008-01-26 14:19:22 +00005951- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005952 added.
5953
Christian Heimesc94e2b52008-01-14 04:13:37 +00005954- sys.float_info / PyFloat_GetInfo: The floating point information
5955 object was converted from a dict to a specialized structseq object.
5956
Georg Brandl3ee81df2008-05-17 18:14:43 +00005957- Patch #1816: Added sys.flags structseq. It exposes the status of
5958 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005959
Georg Brandl3ee81df2008-05-17 18:14:43 +00005960- Objects/structseq.c: Implemented new structseq representation. The
5961 patch makes structseqs (e.g. the return value of os.stat) more
5962 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005963
Georg Brandl3ee81df2008-05-17 18:14:43 +00005964- Patch #1700288: added a type attribute cache that caches method
5965 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005966
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005967- Bug #1776: __import__() no longer accepts filenames on any platform.

Georg Brandlaed6c662008-01-07 17:25:53 +00005970- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5971
Georg Brandl3ee81df2008-05-17 18:14:43 +00005972- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5973 envvar and sys.dont_write_bytecode attribute. All these can be set
5974 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005975
Georg Brandl3ee81df2008-05-17 18:14:43 +00005976- Improve some exception messages when Windows fails to load an
5977 extension module. Now we get for example '%1 is not a valid Win32
5978 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005985- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005986 and INF. float("nan"), float("inf") and float("-inf") now work on
5987 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005988
Georg Brandl3ee81df2008-05-17 18:14:43 +00005989- Compiler now generates simpler and faster code for dictionary
5990 literals. The oparg for BUILD_MAP now indicates an estimated
5991 dictionary size. There is a new opcode, STORE_MAP, for adding
5992 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006021- Patch #1739468: Directories and zipfiles containing a __main__.py
6022 file can now be directly executed by passing their name to the
6023 interpreter. The directory/zipfile is automatically inserted as the
6024 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006026- Issue #1265: Fix a problem with sys.settrace, if the tracing
6027 function uses a generator expression when at the same time the
6028 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006029
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006030- sets and frozensets now have an isdisjoint() method.
6031
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006032- optimize the performance of builtin.sum().
6033
Neal Norwitz44f326e2007-10-05 05:29:17 +00006034- Fix warnings found by the new version of the Coverity checker.
6035
Georg Brandl21e99f42010-03-07 15:23:59 +00006036- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006037 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6038 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006039
Georg Brandl3ee81df2008-05-17 18:14:43 +00006040- Issue #1686386: Tuple's tp_repr did not take into account the
6041 possibility of having a self-referential tuple, which is possible
6042 from C code. Nor did object's tp_str consider that a type's tp_str
6043 could do something that could lead to an inifinite recursion.
6044 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6045 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006046
Georg Brandl3ee81df2008-05-17 18:14:43 +00006047- Issue #1164: It was possible to trigger deadlock when using the
6048 'print' statement to write to a file since the GIL was not released
6049 as needed. Now PyObject_Print() does the right thing along with
6050 various tp_print implementations of the built-in types and those in
6051 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006052
Georg Brandl3ee81df2008-05-17 18:14:43 +00006053- Issue #1147: Exceptions were directly allowing string exceptions in
6054 their throw() method even though string exceptions no longer
6055 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006057- Issue #1096: Prevent a segfault from getting the repr of a very
6058 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006059
Brett Cannon1e534b52007-09-07 04:18:30 +00006060- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006061 PyObject_Call() never calling back out to Python code to trigger
6062 recursion depth updates/checks. Required the creation of a static
6063 RuntimeError instance in case normalizing an exception put the
6064 recursion check value past its limit. Fixes crashers
6065 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006066

Neal Norwitz0ac60192007-05-27 04:08:54 +00006080- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006081 __*__ attributes. (Some already existed, e.g., __doc__ and
6082 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006083
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006084- Add -3 option to the interpreter to warn about features that are
6085 deprecated and will be changed/removed in Python 3.0.
6086
Georg Brandl2134e752007-05-21 20:34:16 +00006087- Patch #1686487: you can now pass any mapping after '**' in function
6088 calls.
6089
Collin Winter62903052007-05-18 23:11:24 +00006090- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006091 "except E as target:". This is to provide forwards compatibility
6092 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006096- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006097 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006099- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006100 setting a plain string, ie don't expand to single letter identifiers.
6101
Raymond Hettinger13936692007-04-11 18:40:58 +00006102- Request #1191699: Slices can now be pickled.
6103
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006104- Request #1193128: str.translate() now allows a None argument for
6105 translations that only remove characters without re-mapping the
6106 remaining characters.
6107
Georg Brandl5cb76c12007-03-21 09:00:39 +00006108- Patch #1682205: a TypeError while unpacking an iterable is no longer
6109 masked by a generic one with the message "unpack non-sequence".
6110
Neal Norwitzaa754b72007-03-21 06:39:48 +00006111- Remove unused file Python/fmod.c.
6112
Guido van Rossum143b5642007-03-23 04:58:42 +00006113- Bug #1683368: The object.__init__() and object.__new__() methods are
6114 now stricter in rejecting excess arguments. The only time when
6115 either allows excess arguments is when it is not overridden and the
6116 other one is. For backwards compatibility, when both are
6117 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006118 warning later). Also, type.__init__() insists on the same signature
6119 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006120
Georg Brandl3ee81df2008-05-17 18:14:43 +00006121- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6122 object to complex using its __complex__() method before falling back
6123 to the __float__() method. Therefore, the functions in the cmath
6124 module now can operate on objects that define a __complex__()
6125 method.

6142
Georg Brandl7b9c5552007-03-12 14:30:05 +00006143- Bug #1678647: write a newline after printing an exception in any
6144 case, even when converting the value to a string failed.
6145
Georg Brandl871f1bc2007-03-12 13:17:36 +00006146- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006147 its argument, if it exists. If not, it will work like before. This
6148 allows customizing the output of dir() in the presence of a
6149 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00006264- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006282 generator expressions (x for x, in ... ) works again. Fixing this
6283 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00006323- Removed uses of dict.has_key() from distutils, and uses of

Facundo Batistad918a652007-04-24 13:54:38 +00006672- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006673 the client's request was successfully received, understood, and

6687
Vinay Sajip8549ce32007-05-06 17:53:37 +00006688- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00006714 AttributeError instead of an IOError when the server's response
6715 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006749 are set for invalid interpolation sequences that would lead to
6750 errors on reading back those values.

6806 TestCase and TestSuite subclasses (not instances) are no longer
6807 accepted in TestSuite.addTest(). This should cause no

Georg Brandl3ee81df2008-05-17 18:14:43 +00007199 time so that opening a database previously created with the DB_DUP
7200 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7201 opens. Specifically: dictionary assignment to a DB object will
7202 replace all values for a given key when the database allows
7203 duplicate values. DB users should use DB.put(k, v) when they want
7204 to store duplicates; not DB[k] = v.

7211 characters with ASCII value less than 32. Also, it correctly quotes
7212 dots only if they occur on a single line, as opposed to the previous
7213 behavior of quoting dots if they are the second character of any
7214 line.
