Martin Panter0d84ea72016-05-22 03:11:44 +0000727- Issue #15348: Stop the debugger engine (normally in a user process)
Terry Jan Reedya3ce2e52015-11-21 13:18:50 -0500728 before closing the debugger window (running in the IDLE process).
729 This prevents the RuntimeErrors that were being caught and ignored.
730
731- Issue #24455: Prevent IDLE from hanging when a) closing the shell while the
732 debugger is active (15347); b) closing the debugger with the [X] button
733 (15348); and c) activating the debugger when already active (24455).
734 The patch by Mark Roseman does this by making two changes.
735 1. Suspend and resume the gui.interaction method with the tcl vwait
736 mechanism intended for this purpose (instead of root.mainloop & .quit).
737 2. In gui.run, allow any existing interaction to terminate first.
738
739- Change 'The program' to 'Your program' in an IDLE 'kill program?' message

Terry Jan Reedy1b6333a2015-10-04 01:14:45 -0400757- Issue #24820: IDLE now has an 'IDLE Dark' built-in text color theme.
758 It is more or less IDLE Classic inverted, with a cobalt blue background.
759 Strings, comments, keywords, ... are still green, red, orange, ... .
Terry Jan Reedya3ce2e52015-11-21 13:18:50 -0500760 To use it with IDLEs released before November 2015, hit the
761 'Save as New Custom Theme' button and enter a new name,
762 such as 'Custom Dark'. The custom theme will work with any IDLE
763 release, and can be modified.

812 The new idlelib/help.html is rstripped Doc/build/html/library/idle.html.
Terry Jan Reedy0eb8f012015-09-20 23:21:17 -0400813 It looks better than help.txt and will better document Idle as released.
Terry Jan Reedy4dd78872015-09-21 19:28:18 -0400814 The tkinter html viewer that works for this file was written by Mark Roseman.
Terry Jan Reedy0eb8f012015-09-20 23:21:17 -0400815 The now unused EditorWindow.HelpDialog class and helt.txt file are deprecated.

2203
2204- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
2205 and later systems as is currently done for Python 3.x installers.
2206 For 2.7.7 only, we will provide three installers:
2207 the legacy deprecated 10.3+ 32-bit-only format;
2208 the newer 10.5+ 32-bit-only format;
2209 and the unchanged 10.6+ 64-/32-bit format.
2210 Although binary installers will no longer be available from
2211 python.org as of 2.7.8, it will still be possible to build from
2212 source on 10.3.9 and 10.4 systems if necessary.
2213 See Mac/BuildScript/README.txt for more information.

Ned Deily18fae3f2013-01-31 01:24:55 -08003593- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
3594 In particular, fix extension module build failures when trying to use
3595 32-bit-only installer Pythons on systems with Xcode 4 (currently
3596 OS X 10.8, 10.7, and optionally 10.6).
3597 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
3598 * Since Xcode 4 removes ppc support, extension module builds now
3599 check for ppc compiler support and by default remove ppc and
3600 ppc64 archs when they are not available.
3601 * Extension module builds now revert to using system installed
3602 headers and libs (/usr and /System/Library) if the SDK used
3603 to build the interpreter is not installed or has moved.
3604 * Try to avoid building extension modules with deprecated
3605 and problematic Apple llvm-gcc compiler. If original compiler
3606 is not available, use clang instead by default.

3974 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01004044 has left two versions of customize_compiler, the original in
4045 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01004050- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
4051 Distutils-based packages with C extension modules may fail because
4052 Apple has removed gcc-4.2, the version used to build python.org
4053 64-bit/32-bit Pythons. If the user does not explicitly override
4054 the default C compiler by setting the CC environment variable,
4055 Distutils will now attempt to compile extension modules with clang
4056 if gcc-4.2 is required but not found. Also as a convenience, if
4057 the user does explicitly set CC, substitute its value as the default
4058 compiler in the Distutils LDSHARED configuration variable for OS X.
4059 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
4060 SDK, neither of which are available in Xcode 4. This change does not
4061 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07004311- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
4312 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
4313 interpreter process. This could cause failures in non-Distutils subprocesses
4314 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02004315 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07004316 deployment target only in the environment of each build subprocess. It is
4317 still possible to globally override the default by setting
4318 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
4319 greater or equal to the default value, the value with which the interpreter
4320 was built.

4350 the ticker doesn't have to wind down to zero from the old starting point
4351 before the new interval takes effect. And if the user increases the
4352 interval, it makes sure the new limit takes effect right away rather have an
4353 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00005350- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
5351 This prevents user-created self-referencing ordered dictionaries from
5352 becoming permanently uncollectable GC garbage. The downside is that
5353 removing __del__ means that the internal doubly-linked list has to wait for
5354 GC collection rather than freeing memory immediately when the refcnt drops
5355 to zero.

5364 original error is re-raised.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00006199- Issue #7301: Add environment variable $PYTHONWARNINGS.
6200
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00006201- Issue #8329: Don't return the same lists from select.select when no fds are
6202 changed.
6203
Georg Brandlfee0f442010-05-22 21:26:21 +00006204- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00006205 on 64-bit machines. The shift count for either left or right shift is
6206 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00006214- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
6215 with a non-empty format string. This is an effort to future-proof user
6216 code. If a derived class does not currently implement __format__ but later
6217 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00006218 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00006219 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00006252- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00006269- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
6270 InvalidOperation instead of returning False. (Comparisons involving a quiet
6271 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
6272 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00006273
Georg Brandlfee0f442010-05-22 21:26:21 +00006274- Issue #2531: Comparison operations between floats and Decimal instances now
6275 return a result based on the numeric values of the operands; previously they
6276 returned an arbitrary result based on the relative ordering of id(float) and
6277 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00006278
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00006279- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00006280 argument `-` which tells it to read files to compile from stdin. Each line is
6281 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00006291- Comparisons using one of <, <=, >, >= between a complex instance and a
6292 Fractions instance now raise TypeError instead of returning True/False. This
6293 makes Fraction <=> complex comparisons consistent with int <=> complex, float
6294 <=> complex, and complex <=> complex comparisons.

6400 the set of integer codes for which it was used differed between native packing
6401 and standard packing.)

6654 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
6655 returning NULL. The macro now returns a statically allocated empty string
6656 instead.

6666 strings,
6667 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long

Georg Brandlba83f822010-03-14 09:50:54 +00006702 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00006708- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00006709 file position when calling `truncate()`. It would previously change the file
6710 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00006711 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
6712

6714 class used to represent files stored inside an archive. The new
Martin Panterb362f752015-11-02 03:37:02 +00006715 implementation is significantly faster and can be wrapped in an
Georg Brandlba83f822010-03-14 09:50:54 +00006716 ``io.BufferedReader`` object for more speedups. It also solves an issue
6717 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
6718 Patch by Nir Aides.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00006800What's New in Python 2.7 alpha 2?
6801=================================

6806-----------------
6807
Georg Brandlba83f822010-03-14 09:50:54 +00006808- The ``__complex__()`` method is now looked up on the class of instances to
6809 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00006810
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00006811- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
6812 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
6813
Mark Dickinson1b34d252010-01-01 17:27:30 +00006814- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00006815 DeprecationWarning when passed a float argument where an integer was expected.
6816 These functions and methods now raise TypeError instead. The majority of the
6817 effects of this change are in the extension modules, but some core functions
6818 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
6819 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00006820

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00006829- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
6830 used to drop the time part of the result.
6831
Georg Brandlba83f822010-03-14 09:50:54 +00006832- Issue #1811: Improve accuracy and cross-platform consistency for true division
6833 of integers: the result of a/b is now correctly rounded for ints a and b (at
6834 least on IEEE 754 platforms), and in particular does not depend on the
6835 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00006836
Georg Brandlba83f822010-03-14 09:50:54 +00006837- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
6838 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
6839 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00006840

Ronald Oussoren92919a62009-12-24 13:30:58 +00006842 executables on OSX.
6843
Georg Brandlba83f822010-03-14 09:50:54 +00006844 These executables now work properly with the arch(1) command: ``arch -ppc
6845 python`` will start a universal binary version of python in PPC mode (unlike
6846 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00006847
Georg Brandlba83f822010-03-14 09:50:54 +00006848- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
6849 underlying error when the coercion fails for the left hand operand.

6860 allowing for a maximum number of tasks within the pool to be completed by the
6861 worker before that worker is terminated, and a new one created to replace it.

Georg Brandlba83f822010-03-14 09:50:54 +00006868 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
6869 alternative to cPickle if you care about performance. Patch by Florent

6906 the same as passing no argument.
6907
Georg Brandlba83f822010-03-14 09:50:54 +00006908- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

6932 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept

Georg Brandlba83f822010-03-14 09:50:54 +00007001- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
7002 decimal string that's guaranteed to round back to x under correct rounding
7003 (with round-half-to-even rounding mode). Previously it gave a string based on
7004 rounding x to 17 decimal digits. repr(x) for a complex number behaves
7005 similarly. On platforms where the correctly-rounded strtod and dtoa code is
7006 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00007008- Issue #7117: On almost all platforms: float-to-string and string-to-float
7009 conversions within Python are now correctly rounded. Places these conversions
7010 occur include: str for floats and complex numbers; the float and complex
7011 constructors; old-style and new-style numeric formatting; serialization and
7012 deserialization of floats and complex numbers using marshal, pickle and json;
7013 parsing of float and imaginary literals in Python code; Decimal-to-float
7014 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00007015
Georg Brandlba83f822010-03-14 09:50:54 +00007016 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
7017 providing correctly-rounded strtod and dtoa C functions. This code is
7018 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
7019 the C compiler. There may be a small number of platforms on which correct
7020 operation of this code cannot be guaranteed, so the code is not used: notably,
7021 this applies to platforms where the C double format is not IEEE 754 binary64,
7022 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
7023 and Python's configure script is unable to determine how to change the FPU
7024 precision. On these platforms conversions use the platform strtod and dtoa,

Georg Brandlba83f822010-03-14 09:50:54 +00007027- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
7028 uses the correctly-rounded string <-> float conversions described above (when
7029 available), and so produces correctly rounded results that will display nicely
7030 under the float repr. There are two related small changes: (1) round now
7031 accepts any class with an ``__index__()`` method for its second argument (but
7032 no longer accepts floats for the second argument), and (2) an excessively
7033 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
7034 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00007251- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00007252 untrackable objects are not tracked by the garbage collector. This can reduce
7253 the size of collections and therefore the garbage collection overhead on
7254 long-running programs, depending on their particular use of datatypes.

7384
Georg Brandlba83f822010-03-14 09:50:54 +00007385- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
7386 file objects with closefd=False. The file descriptor is still kept open but
7387 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00007411- On windows, ``os.chdir()`` given unicode was not working if
7412 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
7413 this code path is really executed because I cannot move to such directory on
7414 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00007416- Issue #4069: When ``set.remove(element)`` is used with a set element, the
7417 element is temporarily replaced with an equivalent frozenset. But the
7418 eventual KeyError would always report the empty ``frozenset()`` as the missing

7440 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
7441 step. This avoids problems with counting UTF-8 bytes that ignores the effect
7442 of using the replace error handler in PyUnicode_DecodeUTF8().

8640 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
8641 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
8642 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00008841- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
8842 PyString_FromFormat or PyErr_Format to display size_t values. The macro
8843 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
8844 ``printf`` function, whereas PyString_FromFormat has an independent
8845 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00008942 warnings.catch_warnings() along with some API cleanup. Expanding the tests
8943 for catch_warnings() also led to an improvement in the raising of a
8944 DeprecationWarning related to warnings.warn_explicit().
8945

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00009010What's New in Python 2.6 beta 3?
9011================================
9012
Barry Warsaw07a4a382008-08-21 01:15:08 +00009013*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00009014
9015Core and Builtins
9016-----------------
9017
Guido van Rossumf8402962008-08-20 15:01:50 +00009018- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
9019 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
9020 extensions do not automatically benefit from the class attribute
9021 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
9022 to their tp_flags field if they care. This is a backwards
9023 compatibility feature; in 3.0, all types will use the cache by
9024 default.
9025
Benjamin Petersonf647dc12008-08-20 01:27:30 +00009026- Keyword arguments can now follow starred arguments. (``f(a, *args,
9027 keyword=23)`` is now valid syntax.)
9028
Thomas Heller0ad5ae02008-08-19 19:25:04 +00009029- ctypes function pointers that are COM methods have a boolean True
9030 value again.
9031
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00009032- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
9033 by denying s# to parse objects that have a releasebuffer procedure,
9034 and introducing s*.
9035
Georg Brandl1e13ea92008-08-11 09:07:59 +00009036- Issue #3537: Fix an assertion failure when an empty but presized dict
9037 object was stored in the freelist.
9038
Mark Dickinsonb6467572008-08-04 21:30:09 +00009039- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
9040 ValueError consistently across platforms.
9041
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00009042- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
9043 (64bit Unix, for example), unichr() would truncate its argument and return
9044 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
9045
Neal Norwitze7d8be82008-07-31 17:17:14 +00009046- Apply security patches from Apple.
9047
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00009048- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
9049 PyErr_ExceptionMatches returns 0 when an exception occurs there.
9050
Antoine Pitrou92f82162008-07-25 22:22:08 +00009051- Issue #1819: function calls with several named parameters are now on
9052 average 35% faster (as measured by pybench).
9053
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00009054- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
9055 the python debugger steps into a class statement: the free variables (local
9056 variables defined in an outer scope) would be deleted from the outer scope.
9057
Gregory P. Smith0470bab2008-07-22 04:46:32 +00009058- Issue #2620: Overflow checking when allocating or reallocating memory
9059 was not always being done properly in some python types and extension
9060 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
9061 all been updated to perform better checks and places in the code that
9062 would previously leak memory on the error path when such an allocation
9063 failed have been fixed.

9066-------
9067
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00009068- Issue #3612: Added some missing basic types in ctypes.wintypes.
9069
Benjamin Petersone977ad42008-08-20 01:42:01 +00009070- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
9071 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
9072
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00009073- Issue #2234: distutils failed for some versions of the cygwin compiler. The
9074 version reported by these tools does not necessarily follow the python
9075 version numbering scheme, so the module is less strict when parsing it.
9076
Nick Coghlanf70385a2008-08-18 12:42:46 +00009077- Issue #2235: Added Py3k warnings for types which will become unhashable
9078 under the stricter __hash__ inheritance rules in 3.0. Several types
9079 which did not meet the rules for hash invariants and were already
9080 unhashable in 3.0 have now been explicitly flagged as unhashable in
9081 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
9082 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
9083
Brett Cannon88f801d2008-08-18 00:46:22 +00009084- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
9085 imported into the module but exposed as part of the module's API.
9086
Brett Cannon7b96f072008-08-18 00:41:11 +00009087- Remove an unneeded import of abc.ABCMeta from 'inspect'.
9088
Brett Cannon46225e72008-08-18 00:36:52 +00009089- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00009091- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
9092
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00009093- Issue #3575: Incremental decoder's decode function now takes bytearray
9094 by using 's*' instead of 't#'.
9095
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00009096- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00009097 fails unicode conversion on 2nd parameter. (windows only)
9098
Georg Brandl222e2082010-08-01 22:27:39 +00009099- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00009100 in a redirect.
9101
Brett Cannonabe423e2008-08-16 21:47:07 +00009102- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00009103 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00009104
Martin Panter6a8163a2016-04-15 02:14:19 +00009105- Issue #2776: fixed small issue when handling a URL with double slash
Facundo Batistaeb90b782008-08-16 14:44:07 +00009106 after a 302 response in the case of not going through a proxy.
9107
Antoine Pitroub90a8be2008-08-15 21:03:21 +00009108- Issue #2676: in the email package, content-type parsing was hanging on
9109 pathological input because of quadratic or exponential behaviour of a
9110 regular expression.
9111
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00009112- Issue #3476: binary buffered reading through the new "io" library is now
9113 thread-safe.
9114
Brett Cannonbf3157b2008-08-14 05:00:03 +00009115- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
9116 since mimetools itself is deprecated. Because modules are cached, all
9117 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
9118
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00009119- Issue #3134: shutil referenced undefined WindowsError symbol.
9120
Robert Schuppenies14646332008-08-10 11:01:53 +00009121- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
9122 menu entries were not deleted.
9123
Brett Cannon83e81842008-08-09 23:30:55 +00009124- Copied the implementation of reduce() to _functools.reduce() to have a
9125 version that did not raise a DeprecationWarning under -3.
9126
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00009127- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
9128 a MemoryError rather than silently stop the iteration.
9129
Guido van Rossum59ce9012008-08-09 14:55:34 +00009130- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
9131 to _sre.compile() will now be rejected. This should not affect anybody
9132 since the re.compile() function never generates invalid re-bytecode.
9133
Skip Montanaroa032bf42008-08-08 22:52:51 +00009134- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
9135 upon first access it can be automatically initialized from the csv file if
9136 it wasn't initialized during instantiation.
9137
Brett Cannon3aa2a492008-08-06 22:28:09 +00009138- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
9139 the reload() built-in has been removed.
9140
Brett Cannon7e30b672008-08-04 21:52:25 +00009141- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00009142 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

9145 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
9146 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
9147 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Antoine Pitroude781a42008-08-09 12:43:23 +00009153 asking for a specific length. This problem only affected files opened
9154 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00009155
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00009156- Issue #3449: Update decimal module to use most recent specification
9157 (v. 1.68) and tests (v. 2.58) from IBM.
9158

9210-----------------
9211
Georg Brandl3e483f62008-07-16 22:57:41 +00009212- Issue #3156: Fix inconsistent behavior of the bytearray type: all
9213 its methods now allow for items objects that can be converted to
9214 an integer using operator.index().
9215
Mark Dickinson64b7e502008-07-16 09:40:03 +00009216- Issue #3360: Fix incorrect parsing of '020000000000.0', which
9217 produced a ValueError instead of giving the correct float.
9218
Eric Smitha5fa5a22008-07-16 00:11:49 +00009219- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
9220 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
9221
Mark Dickinson7103aa42008-07-15 19:08:33 +00009222- Issue #3008: the float type has a new instance method 'float.hex'
9223 and a new class method 'float.fromhex' to convert floating-point
9224 numbers to and from hexadecimal strings, respectively.
9225
Nick Coghlan6d6bd442008-07-15 15:40:22 +00009226- Issue #2235: __hash__ is once again inherited by default. To allow
9227 collections.Hashable to remain meaningful in the presence of the
9228 default hash implementation (object.__hash__), it is now possible
9229 to explicit block inheritance of hash by setting __hash__=None at
9230 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
9231 level.
9232
Nick Coghlanb028f502008-07-13 14:52:36 +00009233- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
9234 the parent module cannot be found while performing an absolute import.
9235 This means that an incorrectly defined __package__ attribute will
9236 now only prevent relative imports in that module rather than causing
9237 all imports from that module to fail.
9238
Nick Coghlan14ff9942008-07-08 14:21:42 +00009239- Issue #2517: Allow unicode messages in Exceptions again by correctly

9249 another thread's dictionary.
9250
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00009251- Issue #3004: Minor change to slice.indices(): the start and stop
9252 arguments are now treated identically, making the behaviour easier
9253 to describe and understand. For example, slice(None, -10,
9254 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
9255 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
9256 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00009258- Issue #3219: Calling a function with repeated keyword arguments,
9259 f(a=2, a=23), would not cause a syntax error. This was a regression
9260 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00009261
Georg Brandl278fc502008-07-19 12:46:12 +00009262- Issue #2862: Make int and float freelist management consistent with
9263 other freelists. Changes their CompactFreeList apis into

9270 api functions without holding the GIL, which could lead to a fatal
9271 error when they failed.
9272
Martin v. Löwisaabf4042008-08-02 07:20:25 +00009273- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00009298- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
9299 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00009300 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00009301 content-length. The problem had been corrected in the 2.4 branch, but never
9302 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00009317- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
9318 handling is now the same as that of other special attributes like __name__).

Georg Brandl3ee81df2008-05-17 18:14:43 +00009768- Issue #1631171: Re-implement the 'warnings' module in C (the
9769 original Python code has been kept as backup). This will allow for
9770 using the 'warning's machinery in such places as the parser where
9771 use of pure Python code is not possible. Both the ``showarning()``
9772 and ``formatwarning()`` gain an optional 'line' argument which is
9773 not called by default for backwards-compatibility reasons. Setting
9774 ``warnings.showwarning()`` to an implementation that lacks support
9775 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009838- Issue #2550: The approach used by client/server code for obtaining
9839 ports to listen on in network-oriented tests has been refined in an
9840 effort to facilitate running multiple instances of the entire
9841 regression test suite in parallel without issue.
9842 test_support.bind_port() has been fixed such that it will always
9843 return a unique port -- which wasn't always the case with the
9844 previous implementation, especially if socket options had been set
9845 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
9846 new implementation of bind_port() will actually raise an exception
9847 if it is passed an AF_INET/SOCK_STREAM socket with either the
9848 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
9849 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
9850 the socket it's been passed. This currently only applies to
9851 Windows. This option prevents any other sockets from binding to the
9852 host/port we've bound to, thus removing the possibility of the
9853 'non-deterministic' behaviour, as Microsoft puts it, that occurs
9854 when a second SOCK_STREAM socket binds and accepts to a host/port
9855 that's already been bound by another socket. The optional preferred
9856 port parameter to bind_port() has been removed. Under no
9857 circumstances should tests be hard coding ports!
9858
9859 test_support.find_unused_port() has also been introduced, which will
9860 pass a temporary socket object to bind_port() in order to obtain an
9861 unused port. The temporary socket object is then closed and
9862 deleted, and the port is returned. This method should only be used
9863 for obtaining an unused port in order to pass to an external program
9864 (i.e. the -accept [port] argument to openssl's s_server mode) or as
9865 a parameter to a server-oriented class that doesn't give you direct
9866 access to the underlying socket used.
9867
9868 Finally, test_support.HOST has been introduced, which should be used
9869 for the host argument of any relevant socket calls (i.e. bind and
9870 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00009871
9872 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00009873 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00009874 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
9875 test_asynchat and test_socket_ssl.
9876
Georg Brandl3ee81df2008-05-17 18:14:43 +00009877 It is now possible for multiple instances of the regression test
9878 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +000010157- Added the future_builtins module, which contains hex() and oct().
10158 These are the PEP 3127 version of these functions, designed to be
10159 compatible with the hex() and oct() builtins from Python 3.0. They
10160 differ slightly in their output formats from the existing, unchanged
10161 Python 2.6 builtins. The expected usage of the future_builtins
10162 module is:
10163 from future_builtins import hex, oct
10164
Eric Smith7ef40bf2008-02-20 23:34:22 +000010165- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
10166 exponents for exponents with absolute value < 100. Follows C99
10167 standard. This is a change on Windows, which would use 3 digits.
10168 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
10169 so that any alterations it does to the resulting string will be
10170 available in stringlib/formatter.h (for float.__format__).
10171
Eric Smith5a3c1352008-02-19 13:21:56 +000010172- Implemented PEP 3101, Advanced String Formatting. This adds a new
10173 builtin format(); a format() method for str and unicode; a
10174 __format__() method to object, str, unicode, int, long, float, and
10175 datetime; the class string.Formatter; and the C API
10176 PyObject_Format().
10177
Georg Brandl3ee81df2008-05-17 18:14:43 +000010178- Fixed several potential crashes, all caused by specially crafted
10179 __del__ methods exploiting objects in temporarily inconsistent
10180 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +000010181
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010182- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +000010183 prevent a possible crash: an Abstract Base Class would try to access

10190 in order to allow pymalloc to free more arenas. Python may give back
10191 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +000010192
Georg Brandl3ee81df2008-05-17 18:14:43 +000010193- Issue #2045: Fix an infinite recursion triggered when printing a
10194 subclass of collections.defaultdict, if its default_factory is set
10195 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +000010196
Christian Heimesf75dbef2008-02-08 00:11:31 +000010197- Fixed a minor memory leak in dictobject.c. The content of the free
10198 list was not freed on interpreter shutdown.
10199
Georg Brandl21e99f42010-03-07 15:23:59 +000010200- Limit free list of method and built-in function objects to 256

Christian Heimes422051a2008-02-04 18:00:12 +000010205 to compact the internal free lists of pre-allocted ints and floats.
10206
Georg Brandl3ee81df2008-05-17 18:14:43 +000010207- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
10208 calls. Python expected the return type int but the fork familie
10209 returns pi_t.

10221 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +000010222
Georg Brandl3ee81df2008-05-17 18:14:43 +000010223- Patch #1473257: generator objects gain a gi_code attribute. This is
10224 the same object as the func_code attribute of the function that
10225 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +000010226
Georg Brandl3ee81df2008-05-17 18:14:43 +000010227- Issue #1920: "while 0" statements were completely removed by the
10228 compiler, even in the presence of an "else" clause, which is
10229 supposed to be run when the condition is false. Now the compiler
10230 correctly emits bytecode for the "else" suite.

Vinay Sajipd7cf32e2008-01-24 12:43:33 +000010236- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +000010237 suppressed while an extension is loaded by calling SetErrorMode in
10238 dynload_win.c. The error is still reported properly.
10239
Georg Brandl3ee81df2008-05-17 18:14:43 +000010240- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +000010241 several extension methods and modules do not work without unicode
10242 support.
10243
Georg Brandl26543b12008-01-21 18:36:51 +000010244- Issue #1882: when compiling code from a string, encoding cookies in the
10245 second line of code were not always recognized correctly.
10246
Georg Brandl14404b62008-01-19 19:27:05 +000010247- Issue #1679: "0x" was taken as a valid integer literal.
10248
Georg Brandl6caad7d2008-01-26 14:19:22 +000010249- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +000010250 added.
10251
Christian Heimesc94e2b52008-01-14 04:13:37 +000010252- sys.float_info / PyFloat_GetInfo: The floating point information
10253 object was converted from a dict to a specialized structseq object.
10254
Georg Brandl3ee81df2008-05-17 18:14:43 +000010255- Patch #1816: Added sys.flags structseq. It exposes the status of
10256 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +000010257
Georg Brandl3ee81df2008-05-17 18:14:43 +000010258- Objects/structseq.c: Implemented new structseq representation. The
10259 patch makes structseqs (e.g. the return value of os.stat) more
10260 readable.
Christian Heimes9c201962008-01-14 03:33:52 +000010261
Georg Brandl3ee81df2008-05-17 18:14:43 +000010262- Patch #1700288: added a type attribute cache that caches method
10263 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +000010264
Neal Norwitz3fc15b82008-01-10 05:42:58 +000010265- Bug #1776: __import__() no longer accepts filenames on any platform.
10266 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +000010267
Georg Brandlaed6c662008-01-07 17:25:53 +000010268- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
10269
Georg Brandl3ee81df2008-05-17 18:14:43 +000010270- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
10271 envvar and sys.dont_write_bytecode attribute. All these can be set
10272 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +000010273
Georg Brandl3ee81df2008-05-17 18:14:43 +000010274- Improve some exception messages when Windows fails to load an
10275 extension module. Now we get for example '%1 is not a valid Win32
10276 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +000010277
Georg Brandl3ee81df2008-05-17 18:14:43 +000010278- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010280- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
10281 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +000010282
Christian Heimes0a8143f2007-12-18 23:22:54 +000010283- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +000010284 and INF. float("nan"), float("inf") and float("-inf") now work on
10285 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +000010286
Georg Brandl3ee81df2008-05-17 18:14:43 +000010287- Compiler now generates simpler and faster code for dictionary
10288 literals. The oparg for BUILD_MAP now indicates an estimated
10289 dictionary size. There is a new opcode, STORE_MAP, for adding
10290 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +000010291

Georg Brandl3ee81df2008-05-17 18:14:43 +000010294- Issue #1620: New property decorator syntax was modifying the
10295 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +000010296
Georg Brandl3ee81df2008-05-17 18:14:43 +000010297- Issue #1538: Avoid copying string in split/rsplit if the split char
10298 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +000010299
Andrew M. Kuchling395fe442007-12-05 13:27:20 +000010300- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +000010301 SystemError.
10302
Nick Coghlanef01d822007-12-03 12:55:17 +000010303- PEP 366: Allow explicit relative imports when executing modules
10304 inside packages with the -m switch via a new module level
10305 __package__ attribute.
10306
Georg Brandl3ee81df2008-05-17 18:14:43 +000010307- Issue #1402: Fix a crash on exit, when another thread is still
10308 running, and if the deallocation of its frames somehow calls the
10309 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +000010310

10312
Vinay Sajip2bdc48c2008-01-21 18:16:05 +000010313- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +000010314 attribute of an empty cell object.
10315
Georg Brandl3ee81df2008-05-17 18:14:43 +000010316- Issue #1460: The utf-7 incremental decoder did not accept truncated
10317 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +000010318
Georg Brandl3ee81df2008-05-17 18:14:43 +000010319- Patch #1739468: Directories and zipfiles containing a __main__.py
10320 file can now be directly executed by passing their name to the
10321 interpreter. The directory/zipfile is automatically inserted as the
10322 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +000010323
Georg Brandl3ee81df2008-05-17 18:14:43 +000010324- Issue #1265: Fix a problem with sys.settrace, if the tracing
10325 function uses a generator expression when at the same time the
10326 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +000010327
Raymond Hettinger1760c8a2007-11-08 02:52:43 +000010328- sets and frozensets now have an isdisjoint() method.
10329
Raymond Hettinger3f8caa32007-10-24 01:28:33 +000010330- optimize the performance of builtin.sum().
10331
Neal Norwitz44f326e2007-10-05 05:29:17 +000010332- Fix warnings found by the new version of the Coverity checker.
10333
Georg Brandl21e99f42010-03-07 15:23:59 +000010334- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +000010335 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
10336 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +000010337
Georg Brandl3ee81df2008-05-17 18:14:43 +000010338- Issue #1686386: Tuple's tp_repr did not take into account the
10339 possibility of having a self-referential tuple, which is possible
10340 from C code. Nor did object's tp_str consider that a type's tp_str
10341 could do something that could lead to an inifinite recursion.
10342 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
10343 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +000010344
Georg Brandl3ee81df2008-05-17 18:14:43 +000010345- Issue #1164: It was possible to trigger deadlock when using the
10346 'print' statement to write to a file since the GIL was not released
10347 as needed. Now PyObject_Print() does the right thing along with
10348 various tp_print implementations of the built-in types and those in
10349 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +000010350
Georg Brandl3ee81df2008-05-17 18:14:43 +000010351- Issue #1147: Exceptions were directly allowing string exceptions in
10352 their throw() method even though string exceptions no longer
10353 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +000010354
Georg Brandl3ee81df2008-05-17 18:14:43 +000010355- Issue #1096: Prevent a segfault from getting the repr of a very
10356 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +000010357
Brett Cannon1e534b52007-09-07 04:18:30 +000010358- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +000010359 PyObject_Call() never calling back out to Python code to trigger
10360 recursion depth updates/checks. Required the creation of a static
10361 RuntimeError instance in case normalizing an exception put the
10362 recursion check value past its limit. Fixes crashers
10363 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +000010364
Georg Brandl3ee81df2008-05-17 18:14:43 +000010365- Patch #1031213: Decode source line in SyntaxErrors back to its
10366 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +000010367
Georg Brandl7c3b50d2007-07-12 08:38:00 +000010368- Patch #1673759: add a missing overflow check when formatting floats
10369 with %G.
10370
Georg Brandl3ee81df2008-05-17 18:14:43 +000010371- Prevent expandtabs() on string and unicode objects from causing a
10372 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +000010373

Georg Brandl3ee81df2008-05-17 18:14:43 +000010376- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +000010377
Neal Norwitz0ac60192007-05-27 04:08:54 +000010378- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +000010379 __*__ attributes. (Some already existed, e.g., __doc__ and
10380 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +000010381
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +000010382- Add -3 option to the interpreter to warn about features that are
10383 deprecated and will be changed/removed in Python 3.0.
10384
Georg Brandl2134e752007-05-21 20:34:16 +000010385- Patch #1686487: you can now pass any mapping after '**' in function
10386 calls.
10387
Collin Winter62903052007-05-18 23:11:24 +000010388- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +000010389 "except E as target:". This is to provide forwards compatibility
10390 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +000010391
Brett Cannon229cee22007-05-05 01:34:02 +000010392- Deprecate BaseException.message as per PEP 352.
10393
Georg Brandl3ee81df2008-05-17 18:14:43 +000010394- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +000010395 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +000010396
Vinay Sajip8549ce32007-05-06 17:53:37 +000010397- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +000010398 setting a plain string, ie don't expand to single letter identifiers.
10399
Serhiy Storchaka16870742015-08-09 13:07:06 +030010400- Request #1191699: Slices can now be pickled.
Raymond Hettinger13936692007-04-11 18:40:58 +000010401
Serhiy Storchaka16870742015-08-09 13:07:06 +030010402- Request #1193128: str.translate() now allows a None argument for
Raymond Hettinger4db5fe92007-04-12 04:10:00 +000010403 translations that only remove characters without re-mapping the
10404 remaining characters.
10405
Georg Brandl5cb76c12007-03-21 09:00:39 +000010406- Patch #1682205: a TypeError while unpacking an iterable is no longer
10407 masked by a generic one with the message "unpack non-sequence".
10408
Neal Norwitzaa754b72007-03-21 06:39:48 +000010409- Remove unused file Python/fmod.c.
10410
Guido van Rossum143b5642007-03-23 04:58:42 +000010411- Bug #1683368: The object.__init__() and object.__new__() methods are
10412 now stricter in rejecting excess arguments. The only time when
10413 either allows excess arguments is when it is not overridden and the
10414 other one is. For backwards compatibility, when both are
10415 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +000010416 warning later). Also, type.__init__() insists on the same signature
10417 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +000010418
Georg Brandl3ee81df2008-05-17 18:14:43 +000010419- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
10420 object to complex using its __complex__() method before falling back
10421 to the __float__() method. Therefore, the functions in the cmath
10422 module now can operate on objects that define a __complex__()
10423 method.
Georg Brandl2b869942007-03-17 16:08:45 +000010424
Georg Brandl3ee81df2008-05-17 18:14:43 +000010425- Patch #1623563: allow __class__ assignment for classes with
10426 __slots__. The old and the new class are still required to have the
10427 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +000010428
Georg Brandl3ee81df2008-05-17 18:14:43 +000010429- Patch #1642547: Fix an error/crash when encountering syntax errors

10433 ``object.__reduce_ex__()`` is called with an object that is faking
10434 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +000010435
Martin Panter6a8163a2016-04-15 02:14:19 +000010436- Patch #1680015: Don't modify __slots__ tuple if it contains a
Georg Brandl3ee81df2008-05-17 18:14:43 +000010437 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +000010438
Georg Brandl5240d742007-03-13 20:46:32 +000010439- Patch #1444529: the builtin compile() now accepts keyword arguments.
10440
Georg Brandl7b9c5552007-03-12 14:30:05 +000010441- Bug #1678647: write a newline after printing an exception in any
10442 case, even when converting the value to a string failed.
10443
Georg Brandl871f1bc2007-03-12 13:17:36 +000010444- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +000010445 its argument, if it exists. If not, it will work like before. This
10446 allows customizing the output of dir() in the presence of a
10447 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +000010448
Collin Winter276887b2007-03-12 16:11:39 +000010449- Patch #922167: Python no longer segfaults when faced with infinitely
10450 self-recursive reload() calls (as reported by bug #742342).
10451
Georg Brandl3ee81df2008-05-17 18:14:43 +000010452- Patch #1675981: remove unreachable code from ``type.__new__()``
10453 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +000010454
Georg Brandl3ee81df2008-05-17 18:14:43 +000010455- Patch #1491866: change the complex() constructor to allow
10456 parthensized forms. This means complex(repr(x)) now works instead of
10457 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +000010458
Georg Brandlaa2321b2007-03-07 00:40:28 +000010459- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl3ee81df2008-05-17 18:14:43 +000010970 the client's request was successfully received, understood, and
10971 accepted. Now in these cases no error is raised in urllib (issue
10972 #1177) and urllib2.

10981 (telnetlib, ftplib, smtplib and poplib). This is second part of the
10982 work started with create_connection() and timeout in httplib, and
10983 closes patch #723312.
10984
Vinay Sajip8549ce32007-05-06 17:53:37 +000010985- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +000011029- Patch #1530482: add pydoc.render_doc() which returns the
11030 documentation for a thing instead of paging it to stdout, which

Georg Brandl3ee81df2008-05-17 18:14:43 +000011046 are set for invalid interpolation sequences that would lead to
11047 errors on reading back those values.

Georg Brandl3ee81df2008-05-17 18:14:43 +000011102- unittest now verifies more of its assumptions. In particular,
11103 TestCase and TestSuite subclasses (not instances) are no longer
11104 accepted in TestSuite.addTest(). This should cause no

11106 -- the failure just occurred later, with a more cumbersome
11107 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +000011490 time so that opening a database previously created with the DB_DUP
11491 or DB_DUPSORT flag set will keep the proper behavior on subsequent
11492 opens. Specifically: dictionary assignment to a DB object will
11493 replace all values for a given key when the database allows
11494 duplicate values. DB users should use DB.put(k, v) when they want
11495 to store duplicates; not DB[k] = v.

11504 behavior of quoting dots if they are the second character of any
11505 line.
