Terry Jan Reedya3ce2e52015-11-21 13:18:50 -0500392- Issue 15348: Stop the debugger engine (normally in a user process)
393 before closing the debugger window (running in the IDLE process).
394 This prevents the RuntimeErrors that were being caught and ignored.
395
396- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
397 debugger is active (15347); b) closing the debugger with the [X] button
398 (15348); and c) activating the debugger when already active (24455).
399 The patch by Mark Roseman does this by making two changes.
400 1. Suspend and resume the gui.interaction method with the tcl vwait
401 mechanism intended for this purpose (instead of root.mainloop & .quit).
402 2. In gui.run, allow any existing interaction to terminate first.
403
404- Change 'The program' to 'Your program' in an IDLE 'kill program?' message
405 to make it clearer that the program referred to is the currently running

420 about the other buttons and the new IDLE Dark theme.
421
Terry Jan Reedy1b6333a2015-10-04 01:14:45 -0400422- Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
423 It is more or less IDLE Classic inverted, with a cobalt blue background.
424 Strings, comments, keywords, ... are still green, red, orange, ... .
Terry Jan Reedya3ce2e52015-11-21 13:18:50 -0500425 To use it with IDLEs released before November 2015, hit the
426 'Save as New Custom Theme' button and enter a new name,
427 such as 'Custom Dark'. The custom theme will work with any IDLE
428 release, and can be modified.

Terry Jan Reedy0eb8f012015-09-20 23:21:17 -0400478 It looks better than help.txt and will better document Idle as released.
Terry Jan Reedy4dd78872015-09-21 19:28:18 -0400479 The tkinter html viewer that works for this file was written by Mark Roseman.
Terry Jan Reedy0eb8f012015-09-20 23:21:17 -0400480 The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated.

1867--------
1868
1869- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1870 and later systems as is currently done for Python 3.x installers.
1871 For 2.7.7 only, we will provide three installers:
1872 the legacy deprecated 10.3+ 32-bit-only format;
1873 the newer 10.5+ 32-bit-only format;
1874 and the unchanged 10.6+ 64-/32-bit format.
1875 Although binary installers will no longer be available from
1876 python.org as of 2.7.8, it will still be possible to build from
1877 source on 10.3.9 and 10.4 systems if necessary.
1878 See Mac/BuildScript/README.txt for more information.

Ned Deily18fae3f2013-01-31 01:24:55 -08003258- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
3259 In particular, fix extension module build failures when trying to use
3260 32-bit-only installer Pythons on systems with Xcode 4 (currently
3261 OS X 10.8, 10.7, and optionally 10.6).
3262 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
3263 * Since Xcode 4 removes ppc support, extension module builds now
3264 check for ppc compiler support and by default remove ppc and
3265 ppc64 archs when they are not available.
3266 * Extension module builds now revert to using system installed
3267 headers and libs (/usr and /System/Library) if the SDK used
3268 to build the interpreter is not installed or has moved.
3269 * Try to avoid building extension modules with deprecated
3270 and problematic Apple llvm-gcc compiler. If original compiler
3271 is not available, use clang instead by default.

3636 int.__pow__. These overflow checks were causing int.__pow__ to produce
3637 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01003638 compiler optimizing the check away. Also fix similar overflow checks
3639 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01003709 has left two versions of customize_compiler, the original in
3710 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01003715- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
3716 Distutils-based packages with C extension modules may fail because
3717 Apple has removed gcc-4.2, the version used to build python.org
3718 64-bit/32-bit Pythons. If the user does not explicitly override
3719 the default C compiler by setting the CC environment variable,
3720 Distutils will now attempt to compile extension modules with clang
3721 if gcc-4.2 is required but not found. Also as a convenience, if
3722 the user does explicitly set CC, substitute its value as the default
3723 compiler in the Distutils LDSHARED configuration variable for OS X.
3724 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
3725 SDK, neither of which are available in Xcode 4. This change does not
3726 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003976- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3977 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3978 interpreter process. This could cause failures in non-Distutils subprocesses
3979 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003980 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003981 deployment target only in the environment of each build subprocess. It is
3982 still possible to globally override the default by setting
3983 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3984 greater or equal to the default value, the value with which the interpreter
3985 was built.

4014 updating the check interval, so if the user decreases the check interval,
4015 the ticker doesn't have to wind down to zero from the old starting point
4016 before the new interval takes effect. And if the user increases the
4017 interval, it makes sure the new limit takes effect right away rather have an
4018 early task switch before recognizing the new interval.

Antoine Pitrouf7f390a2010-09-14 14:37:18 +00005001- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
5002 SSLSocket.sendto() to match the corresponding socket methods. Also,
5003 fix various SSLSocket methods to raise socket.error rather than an

5005 by Andrew Bennetts.

5014
Raymond Hettinger20397532010-09-12 02:11:45 +00005015- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
5016 This prevents user-created self-referencing ordered dictionaries from
5017 becoming permanently uncollectable GC garbage. The downside is that
5018 removing __del__ means that the internal doubly-linked list has to wait for
5019 GC collection rather than freeing memory immediately when the refcnt drops
5020 to zero.
5021

5089 patch by Jason V. Miller.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00005839 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
5840 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
5841 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

5861Core and Builtins
5862-----------------
5863
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00005864- Issue #7301: Add environment variable $PYTHONWARNINGS.
5865
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00005866- Issue #8329: Don't return the same lists from select.select when no fds are
5867 changed.
5868
Georg Brandlfee0f442010-05-22 21:26:21 +00005869- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005870 on 64-bit machines. The shift count for either left or right shift is
5871 permitted to be up to sys.maxsize.
5872
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00005873- Ensure that tokenization of identifiers is not affected by locale.
5874
Georg Brandlfee0f442010-05-22 21:26:21 +00005875- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00005876
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00005877- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
5878
Georg Brandlfee0f442010-05-22 21:26:21 +00005879- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5880 with a non-empty format string. This is an effort to future-proof user
5881 code. If a derived class does not currently implement __format__ but later
5882 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005883 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005884 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00005885
Antoine Pitroua57df2c2010-03-31 21:32:15 +00005886- Issue #8268: Old-style classes (not just instances) now support weak

5898
Victor Stinner66644262010-03-10 22:30:19 +00005899- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00005900 (SIGINT). If an error occurs while importing the site module, the error is
5901 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00005902 module.

5916
Georg Brandlfee0f442010-05-22 21:26:21 +00005917- Issue #8257: The Decimal construct now accepts a float instance directly,
5918 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005919
5920 >>> Decimal(1.1)
5921 Decimal('1.100000000000000088817841970012523233890533447265625')
5922
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005923- collections.Counter() now supports a subtract() method.
5924
Georg Brandlfee0f442010-05-22 21:26:21 +00005925- The functools module now has a total_ordering() class decorator to simplify
5926 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00005927
Georg Brandlfee0f442010-05-22 21:26:21 +00005928- The functools module also adds cmp_to_key() as a tool to transition old-style
5929 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005930
Georg Brandlfee0f442010-05-22 21:26:21 +00005931- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5932 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00005933
Georg Brandlfee0f442010-05-22 21:26:21 +00005934- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5935 InvalidOperation instead of returning False. (Comparisons involving a quiet
5936 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5937 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005938
Georg Brandlfee0f442010-05-22 21:26:21 +00005939- Issue #2531: Comparison operations between floats and Decimal instances now
5940 return a result based on the numeric values of the operands; previously they
5941 returned an arbitrary result based on the relative ordering of id(float) and
5942 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005943
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005944- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005945 argument `-` which tells it to read files to compile from stdin. Each line is
5946 read on demand and the named file is compiled immediately. (Original patch by
5947 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005948
Georg Brandlfee0f442010-05-22 21:26:21 +00005949- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00005952- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5953 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005954 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005955
Georg Brandlfee0f442010-05-22 21:26:21 +00005956- Comparisons using one of <, <=, >, >= between a complex instance and a
5957 Fractions instance now raise TypeError instead of returning True/False. This
5958 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5959 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00005960

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005970- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00005971 didn't support chflags() (for example ZFS under FreeBSD). The error is now
5972 silenced.

Georg Brandlfee0f442010-05-22 21:26:21 +00006015 for ``TimedRotatingFileHandler`` by using the modification time of an existing
6016 log file to compute the next rollover time. If the log file does not exist,
6017 the current time is used as the basis for the computation.

6064 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
6065 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00006066 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
6067 inconsistent: __int__ was used for some integer codes but not for others, and
6068 the set of integer codes for which it was used differed between native packing
6069 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00006377 file position when calling `truncate()`. It would previously change the file
6378 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00006379 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
6380

6382 class used to represent files stored inside an archive. The new
6383 implementation is significantly faster and can be wrapped in a
6384 ``io.BufferedReader`` object for more speedups. It also solves an issue
6385 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
6386 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00006396- Issue #7748: Since unicode values are supported for some metadata options in
6397 Distutils, the DistributionMetadata get_* methods will now return an utf-8
6398 encoded string for them. This ensures that the upload and register commands
6399 send the correct values to PyPI without any error.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00006668
Georg Brandlba83f822010-03-14 09:50:54 +00006669- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
6670 decimal string that's guaranteed to round back to x under correct rounding
6671 (with round-half-to-even rounding mode). Previously it gave a string based on
6672 rounding x to 17 decimal digits. repr(x) for a complex number behaves
6673 similarly. On platforms where the correctly-rounded strtod and dtoa code is
6674 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006675
Georg Brandlba83f822010-03-14 09:50:54 +00006676- Issue #7117: On almost all platforms: float-to-string and string-to-float
6677 conversions within Python are now correctly rounded. Places these conversions
6678 occur include: str for floats and complex numbers; the float and complex
6679 constructors; old-style and new-style numeric formatting; serialization and
6680 deserialization of floats and complex numbers using marshal, pickle and json;
6681 parsing of float and imaginary literals in Python code; Decimal-to-float
6682 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006683
Georg Brandlba83f822010-03-14 09:50:54 +00006684 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
6685 providing correctly-rounded strtod and dtoa C functions. This code is
6686 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
6687 the C compiler. There may be a small number of platforms on which correct
6688 operation of this code cannot be guaranteed, so the code is not used: notably,
6689 this applies to platforms where the C double format is not IEEE 754 binary64,
6690 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
6691 and Python's configure script is unable to determine how to change the FPU
6692 precision. On these platforms conversions use the platform strtod and dtoa,
6693 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00006694
Georg Brandlba83f822010-03-14 09:50:54 +00006695- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
6696 uses the correctly-rounded string <-> float conversions described above (when
6697 available), and so produces correctly rounded results that will display nicely
6698 under the float repr. There are two related small changes: (1) round now
6699 accepts any class with an ``__index__()`` method for its second argument (but
6700 no longer accepts floats for the second argument), and (2) an excessively
6701 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
6702 raises an exception.

6851 but with at least one decimal point and with a default precision
6852 of 12. Previously, the behavior the same but with a default precision of 6.
6853 This more closely matches ``str()``, and reduces surprises when adding

6994
Georg Brandlba83f822010-03-14 09:50:54 +00006995- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
6996 existing .py counterpart, override the co_filename attributes of all code
6997 objects if the original filename is obsolete (which can happen if the file has

7045 instead of throwing a MemoryError.
7046
Georg Brandlba83f822010-03-14 09:50:54 +00007047- Issue #3689: The list reversed iterator now supports __length_hint__ instead

7052
Georg Brandlba83f822010-03-14 09:50:54 +00007053- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
7054 file objects with closefd=False. The file descriptor is still kept open but
7055 the file object behaves like a closed file. The ``FileIO`` object also got a
7056 new readonly attribute ``closefd``.

7075
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00007076- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00007077 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00007079- On windows, ``os.chdir()`` given unicode was not working if
7080 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
7081 this code path is really executed because I cannot move to such directory on
7082 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00007084- Issue #4069: When ``set.remove(element)`` is used with a set element, the
7085 element is temporarily replaced with an equivalent frozenset. But the
7086 eventual KeyError would always report the empty ``frozenset()`` as the missing
7087 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00007107- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
7108 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
7109 step. This avoids problems with counting UTF-8 bytes that ignores the effect
7110 of using the replace error handler in PyUnicode_DecodeUTF8().
7111
Walter Dörwald726ba8e2009-05-06 14:32:35 +00007112- Issue #3739: The unicode-internal encoder now reports the number of characters

7114
Georg Brandlba83f822010-03-14 09:50:54 +00007115- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
7116 allocator will be automatically disabled when running under Valgrind. This
7117 gives improved memory leak detection when running under Valgrind, while taking
7118 advantage of pymalloc at other times.

8508
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00008509- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
8510 PyString_FromFormat or PyErr_Format to display size_t values. The macro
8511 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
8512 ``printf`` function, whereas PyString_FromFormat has an independent
8513 implementation and uses "%zd" on all platforms for size_t values.
8514 This makes a difference on win64, where ``printf`` needs "%Id" to display
8515 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00008517- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

8521 object; previously an int would be returned for small values. the __long__
8522 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00008532 was correctly parsed but parsing of subsequent arguments failed.
8533
Vinay Sajip35e3b032008-09-01 14:33:59 +00008534- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00008535 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
8536 mechanism. In the process, fix a bug where isinstance() and issubclass(),

8538 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
8539 type object.

Gregory P. Smithd7122032008-09-02 05:36:11 +00008625- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
8626 non-integer floating point number.
8627

8633
Jesse Noller438195f2009-01-18 21:04:36 +00008634- Issue #4301: Patch the logging module to add processName support, remove
8635 _check_logger_class from multiprocessing.
8636
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00008637- Issue #2975: When compiling several extension modules with Visual Studio 2008
8638 from the same python interpreter, some environment variables would grow
8639 without limit.
8640
Benjamin Peterson37346b22008-08-23 20:27:43 +00008641- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
8642 exploitation of poor argument checking.
8643

8657 wrapper for warnings.catch_warnings() that makes it easier to check
8658 that expected warning messages are being reported.
8659
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00008660- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008678What's New in Python 2.6 beta 3?
8679================================
8680
Barry Warsaw07a4a382008-08-21 01:15:08 +00008681*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008682
8683Core and Builtins
8684-----------------
8685
Guido van Rossumf8402962008-08-20 15:01:50 +00008686- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
8687 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
8688 extensions do not automatically benefit from the class attribute
8689 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
8690 to their tp_flags field if they care. This is a backwards
8691 compatibility feature; in 3.0, all types will use the cache by
8692 default.
8693
Benjamin Petersonf647dc12008-08-20 01:27:30 +00008694- Keyword arguments can now follow starred arguments. (``f(a, *args,
8695 keyword=23)`` is now valid syntax.)
8696
Thomas Heller0ad5ae02008-08-19 19:25:04 +00008697- ctypes function pointers that are COM methods have a boolean True
8698 value again.
8699
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00008700- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
8701 by denying s# to parse objects that have a releasebuffer procedure,
8702 and introducing s*.
8703
Georg Brandl1e13ea92008-08-11 09:07:59 +00008704- Issue #3537: Fix an assertion failure when an empty but presized dict
8705 object was stored in the freelist.
8706
Mark Dickinsonb6467572008-08-04 21:30:09 +00008707- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
8708 ValueError consistently across platforms.
8709
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00008710- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
8711 (64bit Unix, for example), unichr() would truncate its argument and return
8712 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
8713
Neal Norwitze7d8be82008-07-31 17:17:14 +00008714- Apply security patches from Apple.
8715
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00008716- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
8717 PyErr_ExceptionMatches returns 0 when an exception occurs there.
8718
Antoine Pitrou92f82162008-07-25 22:22:08 +00008719- Issue #1819: function calls with several named parameters are now on
8720 average 35% faster (as measured by pybench).
8721
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00008722- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
8723 the python debugger steps into a class statement: the free variables (local
8724 variables defined in an outer scope) would be deleted from the outer scope.
8725
Gregory P. Smith0470bab2008-07-22 04:46:32 +00008726- Issue #2620: Overflow checking when allocating or reallocating memory
8727 was not always being done properly in some python types and extension
8728 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
8729 all been updated to perform better checks and places in the code that
8730 would previously leak memory on the error path when such an allocation
8731 failed have been fixed.
8732
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008733Library
8734-------
8735
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00008736- Issue #3612: Added some missing basic types in ctypes.wintypes.
8737
Benjamin Petersone977ad42008-08-20 01:42:01 +00008738- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
8739 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
8740
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00008741- Issue #2234: distutils failed for some versions of the cygwin compiler. The
8742 version reported by these tools does not necessarily follow the python
8743 version numbering scheme, so the module is less strict when parsing it.
8744
Nick Coghlanf70385a2008-08-18 12:42:46 +00008745- Issue #2235: Added Py3k warnings for types which will become unhashable
8746 under the stricter __hash__ inheritance rules in 3.0. Several types
8747 which did not meet the rules for hash invariants and were already
8748 unhashable in 3.0 have now been explicitly flagged as unhashable in
8749 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
8750 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
8751
Brett Cannon88f801d2008-08-18 00:46:22 +00008752- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8753 imported into the module but exposed as part of the module's API.
8754
Brett Cannon7b96f072008-08-18 00:41:11 +00008755- Remove an unneeded import of abc.ABCMeta from 'inspect'.
8756
Brett Cannon46225e72008-08-18 00:36:52 +00008757- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00008759- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
8760
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008761- Issue #3575: Incremental decoder's decode function now takes bytearray
8762 by using 's*' instead of 't#'.
8763
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008764- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008765 fails unicode conversion on 2nd parameter. (windows only)
8766
Georg Brandl222e2082010-08-01 22:27:39 +00008767- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00008768 in a redirect.
8769
Brett Cannonabe423e2008-08-16 21:47:07 +00008770- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00008771 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00008772
Facundo Batistaeb90b782008-08-16 14:44:07 +00008773- Issue #2776: fixed small issue when handling an URL with double slash
8774 after a 302 response in the case of not going through a proxy.
8775
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008776- Issue #2676: in the email package, content-type parsing was hanging on
8777 pathological input because of quadratic or exponential behaviour of a
8778 regular expression.
8779
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008780- Issue #3476: binary buffered reading through the new "io" library is now
8781 thread-safe.
8782
Brett Cannonbf3157b2008-08-14 05:00:03 +00008783- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8784 since mimetools itself is deprecated. Because modules are cached, all
8785 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8786
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008787- Issue #3134: shutil referenced undefined WindowsError symbol.
8788
Robert Schuppenies14646332008-08-10 11:01:53 +00008789- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8790 menu entries were not deleted.
8791
Brett Cannon83e81842008-08-09 23:30:55 +00008792- Copied the implementation of reduce() to _functools.reduce() to have a
8793 version that did not raise a DeprecationWarning under -3.
8794
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008795- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8796 a MemoryError rather than silently stop the iteration.
8797
Guido van Rossum59ce9012008-08-09 14:55:34 +00008798- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8799 to _sre.compile() will now be rejected. This should not affect anybody
8800 since the re.compile() function never generates invalid re-bytecode.
8801
Skip Montanaroa032bf42008-08-08 22:52:51 +00008802- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8803 upon first access it can be automatically initialized from the csv file if
8804 it wasn't initialized during instantiation.
8805
Brett Cannon3aa2a492008-08-06 22:28:09 +00008806- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8807 the reload() built-in has been removed.
8808
Brett Cannon7e30b672008-08-04 21:52:25 +00008809- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008810 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00008811 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

8818 raised an AttributeError.
8819
Benjamin Peterson01a24322008-07-28 23:35:27 +00008820- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00008821 asking for a specific length. This problem only affected files opened
8822 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00008823
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00008824- Issue #3449: Update decimal module to use most recent specification
8825 (v. 1.68) and tests (v. 2.58) from IBM.

8846
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00008847- Issue #3394: zipfile.writestr sets external attributes when passed a
8848 file name rather than a ZipInfo instance, so files are extracted with
8849 mode 0600 rather than 000 under Unix.
8850
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008851- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
8852 argument in python 2.5, this broke code that subclassed Popen to include its
8853 own poll method. Fixed my moving _deadstate to an _internal_poll method.

8862
Nick Coghlan6e8fef02008-08-18 13:14:22 +00008863- Issue #2235: the C API function PyObject_HashNotImplemented and its
8864 interaction with the tp_hash slot (added in 2.6b2) are now documented
8865
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008866- Issue #643841: The language reference now provides more detailed
8867 coverage of the lookup process for special methods. The disclaimers
8868 regarding lack of coverage of new-style classes have also been
8869 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00008872What's New in Python 2.6 beta 2?
8873================================
8874
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008875*Release date: 17-Jul-2008*
8876
Raymond Hettingere3ae6552008-06-20 04:18:15 +00008877Core and Builtins
8878-----------------
8879
Georg Brandl3e483f62008-07-16 22:57:41 +00008880- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8881 its methods now allow for items objects that can be converted to
8882 an integer using operator.index().
8883
Mark Dickinson64b7e502008-07-16 09:40:03 +00008884- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8885 produced a ValueError instead of giving the correct float.
8886
Eric Smitha5fa5a22008-07-16 00:11:49 +00008887- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8888 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8889
Mark Dickinson7103aa42008-07-15 19:08:33 +00008890- Issue #3008: the float type has a new instance method 'float.hex'
8891 and a new class method 'float.fromhex' to convert floating-point
8892 numbers to and from hexadecimal strings, respectively.
8893
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008894- Issue #2235: __hash__ is once again inherited by default. To allow
8895 collections.Hashable to remain meaningful in the presence of the
8896 default hash implementation (object.__hash__), it is now possible
8897 to explicit block inheritance of hash by setting __hash__=None at
8898 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8899 level.
8900
Nick Coghlanb028f502008-07-13 14:52:36 +00008901- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8902 the parent module cannot be found while performing an absolute import.
8903 This means that an incorrectly defined __package__ attribute will
8904 now only prevent relative imports in that module rather than causing
8905 all imports from that module to fail.
8906
Nick Coghlan14ff9942008-07-08 14:21:42 +00008907- Issue #2517: Allow unicode messages in Exceptions again by correctly
8908 bypassing the instance dictionary when looking up __unicode__ on
8909 new-style classes.
8910
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008911- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8912 set to a custom object whose write() method happens to install

8923 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00009376 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00009377
9378 This is controlled by the configure argument ``--with-universal-archs``:
9379

9381
9382 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
9383
9384 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
9385
9386 This option should be used in combination with ``--enable-universalsdk=``.
9387
9388 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00009437- Issue #1631171: Re-implement the 'warnings' module in C (the
9438 original Python code has been kept as backup). This will allow for
9439 using the 'warning's machinery in such places as the parser where
9440 use of pure Python code is not possible. Both the ``showarning()``
9441 and ``formatwarning()`` gain an optional 'line' argument which is
9442 not called by default for backwards-compatibility reasons. Setting
9443 ``warnings.showwarning()`` to an implementation that lacks support
9444 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009507- Issue #2550: The approach used by client/server code for obtaining
9508 ports to listen on in network-oriented tests has been refined in an
9509 effort to facilitate running multiple instances of the entire
9510 regression test suite in parallel without issue.
9511 test_support.bind_port() has been fixed such that it will always
9512 return a unique port -- which wasn't always the case with the
9513 previous implementation, especially if socket options had been set
9514 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
9515 new implementation of bind_port() will actually raise an exception
9516 if it is passed an AF_INET/SOCK_STREAM socket with either the
9517 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
9518 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
9519 the socket it's been passed. This currently only applies to
9520 Windows. This option prevents any other sockets from binding to the
9521 host/port we've bound to, thus removing the possibility of the
9522 'non-deterministic' behaviour, as Microsoft puts it, that occurs
9523 when a second SOCK_STREAM socket binds and accepts to a host/port
9524 that's already been bound by another socket. The optional preferred
9525 port parameter to bind_port() has been removed. Under no
9526 circumstances should tests be hard coding ports!
9527
9528 test_support.find_unused_port() has also been introduced, which will
9529 pass a temporary socket object to bind_port() in order to obtain an
9530 unused port. The temporary socket object is then closed and
9531 deleted, and the port is returned. This method should only be used
9532 for obtaining an unused port in order to pass to an external program
9533 (i.e. the -accept [port] argument to openssl's s_server mode) or as
9534 a parameter to a server-oriented class that doesn't give you direct
9535 access to the underlying socket used.
9536
9537 Finally, test_support.HOST has been introduced, which should be used
9538 for the host argument of any relevant socket calls (i.e. bind and
9539 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00009540
9541 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00009542 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00009543 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
9544 test_asynchat and test_socket_ssl.
9545
Georg Brandl3ee81df2008-05-17 18:14:43 +00009546 It is now possible for multiple instances of the regression test
9547 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009731 optional: it defaults to the traceback of the exception that is
9732 currently being handled (is mandatory to be in the middle of an
9733 exception, otherwise it raises ValueError).

9752 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009753 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
9754 files are used. On all linux systems the --with-system-ffi
9755 configure option defaults to "yes".

Eric Smitha73fbe72008-02-23 03:09:44 +00009826- Added the future_builtins module, which contains hex() and oct().
9827 These are the PEP 3127 version of these functions, designed to be
9828 compatible with the hex() and oct() builtins from Python 3.0. They
9829 differ slightly in their output formats from the existing, unchanged
9830 Python 2.6 builtins. The expected usage of the future_builtins
9831 module is:
9832 from future_builtins import hex, oct
9833
Eric Smith7ef40bf2008-02-20 23:34:22 +00009834- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9835 exponents for exponents with absolute value < 100. Follows C99
9836 standard. This is a change on Windows, which would use 3 digits.
9837 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9838 so that any alterations it does to the resulting string will be
9839 available in stringlib/formatter.h (for float.__format__).
9840
Eric Smith5a3c1352008-02-19 13:21:56 +00009841- Implemented PEP 3101, Advanced String Formatting. This adds a new
9842 builtin format(); a format() method for str and unicode; a
9843 __format__() method to object, str, unicode, int, long, float, and
9844 datetime; the class string.Formatter; and the C API
9845 PyObject_Format().
9846
Georg Brandl3ee81df2008-05-17 18:14:43 +00009847- Fixed several potential crashes, all caused by specially crafted
9848 __del__ methods exploiting objects in temporarily inconsistent
9849 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009850
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009851- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009852 prevent a possible crash: an Abstract Base Class would try to access
9853 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009854
Georg Brandl3ee81df2008-05-17 18:14:43 +00009855- Fixed repr() and str() of complex numbers with infinity or nan as
9856 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009858- Clear all free lists during a gc.collect() of the highest generation
9859 in order to allow pymalloc to free more arenas. Python may give back
9860 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009861
Georg Brandl3ee81df2008-05-17 18:14:43 +00009862- Issue #2045: Fix an infinite recursion triggered when printing a
9863 subclass of collections.defaultdict, if its default_factory is set
9864 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009865
Christian Heimesf75dbef2008-02-08 00:11:31 +00009866- Fixed a minor memory leak in dictobject.c. The content of the free
9867 list was not freed on interpreter shutdown.
9868
Georg Brandl21e99f42010-03-07 15:23:59 +00009869- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009870 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009871
Georg Brandl3ee81df2008-05-17 18:14:43 +00009872- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9873 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009874 to compact the internal free lists of pre-allocted ints and floats.
9875
Georg Brandl3ee81df2008-05-17 18:14:43 +00009876- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9877 calls. Python expected the return type int but the fork familie
9878 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009879
Georg Brandl3ee81df2008-05-17 18:14:43 +00009880- Issue #1678380: Fix a bug that identifies 0j and -0j when they
9881 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00009882
Georg Brandl3ee81df2008-05-17 18:14:43 +00009883- Issue #2025: Add tuple.count() and tuple.index() methods to comply
9884 with the collections.Sequence API.

9890 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00009891
Georg Brandl3ee81df2008-05-17 18:14:43 +00009892- Patch #1473257: generator objects gain a gi_code attribute. This is
9893 the same object as the func_code attribute of the function that
9894 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009895
Georg Brandl3ee81df2008-05-17 18:14:43 +00009896- Issue #1920: "while 0" statements were completely removed by the
9897 compiler, even in the presence of an "else" clause, which is
9898 supposed to be run when the condition is false. Now the compiler
9899 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009900
Guido van Rossumeead05f2008-01-24 18:21:02 +00009901- A few crashers fixed: weakref_in_del.py (issue #1377858);
9902 loosing_dict_ref.py (issue #1303614, test67.py);
9903 borrowed_ref_[34].py (not in tracker).
9904
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009905- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009906 suppressed while an extension is loaded by calling SetErrorMode in
9907 dynload_win.c. The error is still reported properly.
9908
Georg Brandl3ee81df2008-05-17 18:14:43 +00009909- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009910 several extension methods and modules do not work without unicode
9911 support.
9912
Georg Brandl26543b12008-01-21 18:36:51 +00009913- Issue #1882: when compiling code from a string, encoding cookies in the
9914 second line of code were not always recognized correctly.
9915
Georg Brandl14404b62008-01-19 19:27:05 +00009916- Issue #1679: "0x" was taken as a valid integer literal.
9917
Georg Brandl6caad7d2008-01-26 14:19:22 +00009918- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009919 added.
9920
Christian Heimesc94e2b52008-01-14 04:13:37 +00009921- sys.float_info / PyFloat_GetInfo: The floating point information
9922 object was converted from a dict to a specialized structseq object.
9923
Georg Brandl3ee81df2008-05-17 18:14:43 +00009924- Patch #1816: Added sys.flags structseq. It exposes the status of
9925 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009926
Georg Brandl3ee81df2008-05-17 18:14:43 +00009927- Objects/structseq.c: Implemented new structseq representation. The
9928 patch makes structseqs (e.g. the return value of os.stat) more
9929 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009930
Georg Brandl3ee81df2008-05-17 18:14:43 +00009931- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00009943- Improve some exception messages when Windows fails to load an
9944 extension module. Now we get for example '%1 is not a valid Win32
9945 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009953 and INF. float("nan"), float("inf") and float("-inf") now work on
9954 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009955
Georg Brandl3ee81df2008-05-17 18:14:43 +00009956- Compiler now generates simpler and faster code for dictionary
9957 literals. The oparg for BUILD_MAP now indicates an estimated
9958 dictionary size. There is a new opcode, STORE_MAP, for adding
9959 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009985- Issue #1460: The utf-7 incremental decoder did not accept truncated
9986 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00009987
Georg Brandl3ee81df2008-05-17 18:14:43 +00009988- Patch #1739468: Directories and zipfiles containing a __main__.py
9989 file can now be directly executed by passing their name to the
9990 interpreter. The directory/zipfile is automatically inserted as the
9991 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009993- Issue #1265: Fix a problem with sys.settrace, if the tracing
9994 function uses a generator expression when at the same time the
9995 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009996
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009997- sets and frozensets now have an isdisjoint() method.
9998
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009999- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +000010001- Fix warnings found by the new version of the Coverity checker.
10002
Georg Brandl21e99f42010-03-07 15:23:59 +000010003- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +000010004 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
10005 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +000010006
Georg Brandl3ee81df2008-05-17 18:14:43 +000010007- Issue #1686386: Tuple's tp_repr did not take into account the
10008 possibility of having a self-referential tuple, which is possible
10009 from C code. Nor did object's tp_str consider that a type's tp_str
10010 could do something that could lead to an inifinite recursion.
10011 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
10012 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +000010013
Georg Brandl3ee81df2008-05-17 18:14:43 +000010014- Issue #1164: It was possible to trigger deadlock when using the
10015 'print' statement to write to a file since the GIL was not released
10016 as needed. Now PyObject_Print() does the right thing along with
10017 various tp_print implementations of the built-in types and those in
10018 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +000010019
Georg Brandl3ee81df2008-05-17 18:14:43 +000010020- Issue #1147: Exceptions were directly allowing string exceptions in
10021 their throw() method even though string exceptions no longer
10022 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +000010023
Georg Brandl3ee81df2008-05-17 18:14:43 +000010024- Issue #1096: Prevent a segfault from getting the repr of a very
10025 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +000010026
Brett Cannon1e534b52007-09-07 04:18:30 +000010027- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +000010028 PyObject_Call() never calling back out to Python code to trigger
10029 recursion depth updates/checks. Required the creation of a static
10030 RuntimeError instance in case normalizing an exception put the
10031 recursion check value past its limit. Fixes crashers
10032 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +000010033
Georg Brandl3ee81df2008-05-17 18:14:43 +000010034- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +000010047- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +000010048 __*__ attributes. (Some already existed, e.g., __doc__ and
10049 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +000010050
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +000010051- Add -3 option to the interpreter to warn about features that are
10052 deprecated and will be changed/removed in Python 3.0.
10053
Georg Brandl2134e752007-05-21 20:34:16 +000010054- Patch #1686487: you can now pass any mapping after '**' in function
10055 calls.
10056
Collin Winter62903052007-05-18 23:11:24 +000010057- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +000010058 "except E as target:". This is to provide forwards compatibility
10059 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +000010060
Brett Cannon229cee22007-05-05 01:34:02 +000010061- Deprecate BaseException.message as per PEP 352.
10062
Georg Brandl3ee81df2008-05-17 18:14:43 +000010063- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +000010064 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +000010065
Vinay Sajip8549ce32007-05-06 17:53:37 +000010066- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000010067 setting a plain string, ie don't expand to single letter identifiers.
10068
Serhiy Storchaka16870742015-08-09 13:07:06 +030010069- Request #1191699: Slices can now be pickled.

Serhiy Storchaka16870742015-08-09 13:07:06 +030010071- Request #1193128: str.translate() now allows a None argument for
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000010072 translations that only remove characters without re-mapping the
10073 remaining characters.
10074
Georg Brandl5cb76c12007-03-21 09:00:39 +000010075- Patch #1682205: a TypeError while unpacking an iterable is no longer
10076 masked by a generic one with the message "unpack non-sequence".
10077
Neal Norwitzaa754b72007-03-21 06:39:48 +000010078- Remove unused file Python/fmod.c.
10079
Guido van Rossum143b5642007-03-23 04:58:42 +000010080- Bug #1683368: The object.__init__() and object.__new__() methods are
10081 now stricter in rejecting excess arguments. The only time when
10082 either allows excess arguments is when it is not overridden and the
10083 other one is. For backwards compatibility, when both are
10084 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000010085 warning later). Also, type.__init__() insists on the same signature
10086 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000010087
Georg Brandl3ee81df2008-05-17 18:14:43 +000010088- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
10089 object to complex using its __complex__() method before falling back
10090 to the __float__() method. Therefore, the functions in the cmath
10091 module now can operate on objects that define a __complex__()
10092 method.
Georg Brandl2b869942007-03-17 16:08:45 +000010093
Georg Brandl3ee81df2008-05-17 18:14:43 +000010094- Patch #1623563: allow __class__ assignment for classes with
10095 __slots__. The old and the new class are still required to have the
10096 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000010097

10102 ``object.__reduce_ex__()`` is called with an object that is faking
10103 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000010104
Georg Brandl3ee81df2008-05-17 18:14:43 +000010105- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +000010108- Patch #1444529: the builtin compile() now accepts keyword arguments.
10109
Georg Brandl7b9c5552007-03-12 14:30:05 +000010110- Bug #1678647: write a newline after printing an exception in any
10111 case, even when converting the value to a string failed.
10112
Georg Brandl871f1bc2007-03-12 13:17:36 +000010113- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +000010114 its argument, if it exists. If not, it will work like before. This
10115 allows customizing the output of dir() in the presence of a
10116 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +000010117
Collin Winter276887b2007-03-12 16:11:39 +000010118- Patch #922167: Python no longer segfaults when faced with infinitely
10119 self-recursive reload() calls (as reported by bug #742342).
10120
Georg Brandl3ee81df2008-05-17 18:14:43 +000010121- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +000010124- Patch #1491866: change the complex() constructor to allow
10125 parthensized forms. This means complex(repr(x)) now works instead of
10126 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +000010127
Georg Brandlaa2321b2007-03-07 00:40:28 +000010128- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +000010129 makes the filenames the warning module prints much more sensible
10130 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +000010131
Georg Brandl49aafc92007-03-07 00:34:46 +000010132- Variant of patch #697613: don't exit the interpreter on a SystemExit
10133 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +000010134 variable is given, but break into the interactive interpreter just
10135 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010140- Bug #1674503: close the file opened by execfile() in an error
10141 condition.
Georg Brandl098cd692007-03-06 12:17:50 +000010142
Georg Brandl0fca97a2007-03-05 22:28:08 +000010143- Patch #1674228: when assigning a slice (old-style), check for the

10145
Georg Brandl3ee81df2008-05-17 18:14:43 +000010146- When printing an unraisable error, don't print exceptions. before
10147 the name. This duplicates the behavior whening normally printing
10148 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010698- Patch #1530482: add pydoc.render_doc() which returns the
10699 documentation for a thing instead of paging it to stdout, which

Georg Brandl92a6bae2007-03-13 17:43:32 +000010714- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +000010715 are set for invalid interpolation sequences that would lead to
10716 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +000010717

Georg Brandl3ee81df2008-05-17 18:14:43 +000010771- unittest now verifies more of its assumptions. In particular,
10772 TestCase and TestSuite subclasses (not instances) are no longer
10773 accepted in TestSuite.addTest(). This should cause no

10775 -- the failure just occurred later, with a more cumbersome
10776 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +000011057 that the SMTP.starttls() caller no longer needs to call ehlo()
11058 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000011059 does not claim to support starttls. Adds the
11060 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000011158- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000011159 time so that opening a database previously created with the DB_DUP
11160 or DB_DUPSORT flag set will keep the proper behavior on subsequent
11161 opens. Specifically: dictionary assignment to a DB object will
11162 replace all values for a given key when the database allows
11163 duplicate values. DB users should use DB.put(k, v) when they want
11164 to store duplicates; not DB[k] = v.

11525 of w# format code incorrectly truncated the length to an int, even
11526 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
11527 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +000011557- Added case insensitive comparison methods ``PyOS_stricmp(char*,
11558 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
