Mark Dickinsondbbed042011-09-19 16:38:08 +010052- Issue #12973: Fix overflow checks that invoked undefined behaviour in
53 int.__pow__. These overflow checks were causing int.__pow__ to produce
54 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010055 compiler optimizing the check away. Also fix similar overflow checks
56 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
57 bugs caused test failures with recent versions of Clang.

69 cleared by the garbage collector. This fixes a segfault when an instance
70 and its type get caught in a reference cycle, and the instance's
71 deallocator calls one of the methods on the type (e.g. when subclassing

Victor Stinner08563d92011-05-30 23:44:13 +020081 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
82 raw_input() interrupted by CTRL+c.
83

Ned Deily87e82bb2011-06-28 19:52:59 -0700365- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
366 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
367 interpreter process. This could cause failures in non-Distutils subprocesses
368 and was unreliable since tests or user programs could modify the interpreter
369 environment after Distutils set it. Instead, have Distutils set the the
370 deployment target only in the environment of each build subprocess. It is
371 still possible to globally override the default by setting
372 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
373 greater or equal to the default value, the value with which the interpreter
374 was built.

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

1335 This prevents user-created self-referencing ordered dictionaries from
1336 becoming permanently uncollectable GC garbage. The downside is that

1797
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001798- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1799 start byte and the continuation byte(s) are now considered invalid, instead
1800 of the number of bytes specified by the start byte.
1801 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1802 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1803 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1804 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001806- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001807 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1808 arises from the "Overriding __eq__ blocks inheritance ..." warning
1809 when turned into an exception: in this case the exception simply
1810 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001811
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001812- Issue #8748: Fix two issues with comparisons between complex and integer
1813 objects. (1) The comparison could incorrectly return True in some cases
1814 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1815 (2) The comparison raised an OverflowError for large integers, leading
1816 to unpredictable exceptions when combining integers and complex objects
1817 in sets or dicts.
1818
Mark Dickinson81336372010-05-30 12:12:25 +00001819- Issue #5211: Implicit coercion for the complex type is now completely
1820 removed. (Coercion for arithmetic operations was already removed in 2.7
1821 alpha 4, but coercion for rich comparisons was accidentally left in.)
1822
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001823- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

1825
Georg Brandlfee0f442010-05-22 21:26:21 +00001826- Issue #7902: When using explicit relative import syntax, don't try implicit

2187 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00002199- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2200 with a non-empty format string. This is an effort to future-proof user
2201 code. If a derived class does not currently implement __format__ but later
2202 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002203 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002204 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002265 argument `-` which tells it to read files to compile from stdin. Each line is
2266 read on demand and the named file is compiled immediately. (Original patch by
2267 Piotr Ożarowski).

2277 Fractions instance now raise TypeError instead of returning True/False. This
2278 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2279 <=> complex, and complex <=> complex comparisons.

Antoine Pitroud840e512010-02-04 20:20:18 +00002689- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002690 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002691 Also, raise ValueError rather than TypeError when an unknown TIPC address

Georg Brandlba83f822010-03-14 09:50:54 +00002697 file position when calling `truncate()`. It would previously change the file
2698 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002699 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2700

2702 class used to represent files stored inside an archive. The new
2703 implementation is significantly faster and can be wrapped in a
2704 ``io.BufferedReader`` object for more speedups. It also solves an issue
2705 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2706 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002716- Issue #7748: Since unicode values are supported for some metadata options in
2717 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2718 encoded string for them. This ensures that the upload and register commands
2719 send the correct values to PyPI without any error.

2795
Georg Brandlba83f822010-03-14 09:50:54 +00002796- The ``__complex__()`` method is now looked up on the class of instances to
2797 make it consistent with other special methods.

2801
Mark Dickinson1b34d252010-01-01 17:27:30 +00002802- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002803 DeprecationWarning when passed a float argument where an integer was expected.
2804 These functions and methods now raise TypeError instead. The majority of the
2805 effects of this change are in the extension modules, but some core functions
2806 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2807 and many unicode/str methods.

2821 of integers: the result of a/b is now correctly rounded for ints a and b (at
2822 least on IEEE 754 platforms), and in particular does not depend on the
2823 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00002832 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00002990- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2991 decimal string that's guaranteed to round back to x under correct rounding
2992 (with round-half-to-even rounding mode). Previously it gave a string based on
2993 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2994 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2995 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002997- Issue #7117: On almost all platforms: float-to-string and string-to-float
2998 conversions within Python are now correctly rounded. Places these conversions
2999 occur include: str for floats and complex numbers; the float and complex
3000 constructors; old-style and new-style numeric formatting; serialization and
3001 deserialization of floats and complex numbers using marshal, pickle and json;
3002 parsing of float and imaginary literals in Python code; Decimal-to-float
3003 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003004
Georg Brandlba83f822010-03-14 09:50:54 +00003005 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3006 providing correctly-rounded strtod and dtoa C functions. This code is
3007 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3008 the C compiler. There may be a small number of platforms on which correct
3009 operation of this code cannot be guaranteed, so the code is not used: notably,
3010 this applies to platforms where the C double format is not IEEE 754 binary64,
3011 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3012 and Python's configure script is unable to determine how to change the FPU
3013 precision. On these platforms conversions use the platform strtod and dtoa,
3014 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003016- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3017 uses the correctly-rounded string <-> float conversions described above (when
3018 available), and so produces correctly rounded results that will display nicely
3019 under the float repr. There are two related small changes: (1) round now
3020 accepts any class with an ``__index__()`` method for its second argument (but
3021 no longer accepts floats for the second argument), and (2) an excessively
3022 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3023 raises an exception.

Mark Dickinsonfe67bd92009-07-28 20:35:03 +00004591
Georg Brandlba83f822010-03-14 09:50:54 +00004592- Issue #1523: Remove deprecated overflow wrapping for struct.pack with an
4593 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
4594 consistently raises struct.error.
Mark Dickinson5fd3af22009-07-07 15:08:28 +00004595
Georg Brandlba83f822010-03-14 09:50:54 +00004596- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the

Mark Dickinson463dc4b2009-07-05 10:01:24 +00004599
Georg Brandlba83f822010-03-14 09:50:54 +00004600 - Packing a float now always gives a Deprecation Warning. Previously it
4601 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004602
Georg Brandlba83f822010-03-14 09:50:54 +00004603 - If x is not an int, long or float, then packing x will always result in
4604 struct.error. Previously an x with an __int__ method could be packed by
4605 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4606 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4607 neither __int__ nor __long__, TypeError used to be raised (with a
4608 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4609 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004610
Georg Brandlba83f822010-03-14 09:50:54 +00004611 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
4612 argument with an __int__ method can be packed, but use of this feature
4613 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00004646- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
4647 in the Lib/test directory, which might be read-only for the user running the
4648 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00004649
Georg Brandlba83f822010-03-14 09:50:54 +00004650- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
4651 of an option with no handler.
R. David Murrayda826892009-11-15 00:04:32 +00004652
Georg Brandlba83f822010-03-14 09:50:54 +00004653- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
4654 fails. Can be combined with -j.
R. David Murray7f7eea62009-11-14 15:18:22 +00004655
Antoine Pitrou310c9fe2009-11-11 20:55:07 +00004656- Issue #7295: Do not use a hardcoded file name in test_tarfile.

Antoine Pitrouc98efe02009-11-06 22:34:35 +00004658- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
4659 primitives such as Lock, RLock, Condition, Event and Semaphore.
4660
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004661- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00004662 leak-chasing test runs give sensible results. The previous method of reaping
4663 threads could return successfully while some Thread objects were still
4664 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004665
Georg Brandlba83f822010-03-14 09:50:54 +00004666- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
4667 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00004668
Antoine Pitrou58d2f262009-10-10 20:52:11 +00004669- Issue #7055: test___all__ now greedily detects all modules which have an
4670 __all__ attribute, rather than using a hardcoded and incomplete list.
4671
R. David Murray14dcd432009-10-14 13:58:07 +00004672- Issue #7058: Added save/restore for things like sys.argv and cwd to
4673 runtest_inner in regrtest, with warnings if the called test modifies them,
4674 and a new section in the summary report at the end.
R. David Murrayabe3d3e2009-10-05 17:03:09 +00004675
Mark Dickinson245d9152009-10-04 18:38:39 +00004676- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.

4679 off the trailing 0 in the version number.
4680
Guilherme Polo7f146ab2009-06-21 17:22:50 +00004681- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4682 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004683 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4684 the tests if DISPLAY is defined but can't be used.
Guilherme Polo7f146ab2009-06-21 17:22:50 +00004685
Antoine Pitrou4698d992009-05-31 14:20:14 +00004686- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
4687 regression tests in parallel, shortening the total runtime.
4688
Georg Brandlba83f822010-03-14 09:50:54 +00004689- Issue #5354: New test support function import_fresh_module() makes it easy to
4690 import both normal and optimised versions of modules. test_heapq and
4691 test_warnings have been adjusted to use it, tests for other modules with both
4692 C and Python implementations in the stdlib can be adjusted to use it over
4693 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004701- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4702 should cause a test to be skipped are now done using import_module from test
4703 support, which does the conversion.
R. David Murray41448c52009-03-31 19:57:24 +00004704
Guilherme Polob1a98de2009-01-28 20:03:26 +00004705- Issue #5083: New 'gui' resource for regrtest.

4805
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004806- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4807 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4808 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4809 ``printf`` function, whereas PyString_FromFormat has an independent
4810 implementation and uses "%zd" on all platforms for size_t values.
4811 This makes a difference on win64, where ``printf`` needs "%Id" to display
4812 64bit values.

4826
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004827- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004828 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004829 was correctly parsed but parsing of subsequent arguments failed.
4830
Vinay Sajip35e3b032008-09-01 14:33:59 +00004831- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004832 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4833 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4834 when given a tuple of classes as second argument, were looking up
4835 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4836 type object.
4837
Neal Norwitz18aa3882008-08-24 05:04:52 +00004838- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004907 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4908 for catch_warnings() also led to an improvement in the raising of a
4909 DeprecationWarning related to warnings.warn_explicit().
4910
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004911- The deprecation warnings for the old camelCase threading API were removed.

4933
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004934- Issue #2975: When compiling several extension modules with Visual Studio 2008
4935 from the same python interpreter, some environment variables would grow
4936 without limit.
4937
Benjamin Peterson37346b22008-08-23 20:27:43 +00004938- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4939 exploitation of poor argument checking.
4940
Gerhard Häringef2276b2008-09-12 13:54:06 +00004941- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004975What's New in Python 2.6 beta 3?
4976================================
4977
Barry Warsaw07a4a382008-08-21 01:15:08 +00004978*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004979
4980Core and Builtins
4981-----------------
4982
Guido van Rossumf8402962008-08-20 15:01:50 +00004983- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4984 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4985 extensions do not automatically benefit from the class attribute
4986 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4987 to their tp_flags field if they care. This is a backwards
4988 compatibility feature; in 3.0, all types will use the cache by
4989 default.
4990
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004991- Keyword arguments can now follow starred arguments. (``f(a, *args,
4992 keyword=23)`` is now valid syntax.)
4993
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004994- ctypes function pointers that are COM methods have a boolean True
4995 value again.
4996
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004997- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4998 by denying s# to parse objects that have a releasebuffer procedure,
4999 and introducing s*.
5000
Georg Brandl1e13ea92008-08-11 09:07:59 +00005001- Issue #3537: Fix an assertion failure when an empty but presized dict
5002 object was stored in the freelist.
5003
Mark Dickinsonb6467572008-08-04 21:30:09 +00005004- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5005 ValueError consistently across platforms.
5006
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005007- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5008 (64bit Unix, for example), unichr() would truncate its argument and return
5009 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5010
Neal Norwitze7d8be82008-07-31 17:17:14 +00005011- Apply security patches from Apple.
5012
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005013- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5014 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5015
Antoine Pitrou92f82162008-07-25 22:22:08 +00005016- Issue #1819: function calls with several named parameters are now on
5017 average 35% faster (as measured by pybench).
5018
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005019- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5020 the python debugger steps into a class statement: the free variables (local
5021 variables defined in an outer scope) would be deleted from the outer scope.
5022
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005023- Issue #2620: Overflow checking when allocating or reallocating memory
5024 was not always being done properly in some python types and extension
5025 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5026 all been updated to perform better checks and places in the code that
5027 would previously leak memory on the error path when such an allocation
5028 failed have been fixed.

5031-------
5032
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005033- Issue #3612: Added some missing basic types in ctypes.wintypes.
5034
Benjamin Petersone977ad42008-08-20 01:42:01 +00005035- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5036 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5037
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005038- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5039 version reported by these tools does not necessarily follow the python
5040 version numbering scheme, so the module is less strict when parsing it.
5041
Nick Coghlanf70385a2008-08-18 12:42:46 +00005042- Issue #2235: Added Py3k warnings for types which will become unhashable
5043 under the stricter __hash__ inheritance rules in 3.0. Several types
5044 which did not meet the rules for hash invariants and were already
5045 unhashable in 3.0 have now been explicitly flagged as unhashable in
5046 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5047 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5048
Brett Cannon88f801d2008-08-18 00:46:22 +00005049- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5050 imported into the module but exposed as part of the module's API.
5051
Brett Cannon7b96f072008-08-18 00:41:11 +00005052- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5053
Brett Cannon46225e72008-08-18 00:36:52 +00005054- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005056- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5057
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005058- Issue #3575: Incremental decoder's decode function now takes bytearray
5059 by using 's*' instead of 't#'.
5060
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005061- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005062 fails unicode conversion on 2nd parameter. (windows only)
5063
Georg Brandl222e2082010-08-01 22:27:39 +00005064- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005065 in a redirect.
5066
Brett Cannonabe423e2008-08-16 21:47:07 +00005067- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005068 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005069
Facundo Batistaeb90b782008-08-16 14:44:07 +00005070- Issue #2776: fixed small issue when handling an URL with double slash
5071 after a 302 response in the case of not going through a proxy.
5072
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005073- Issue #2676: in the email package, content-type parsing was hanging on
5074 pathological input because of quadratic or exponential behaviour of a
5075 regular expression.
5076
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005077- Issue #3476: binary buffered reading through the new "io" library is now
5078 thread-safe.
5079
Brett Cannonbf3157b2008-08-14 05:00:03 +00005080- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5081 since mimetools itself is deprecated. Because modules are cached, all
5082 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5083
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005084- Issue #3134: shutil referenced undefined WindowsError symbol.
5085
Robert Schuppenies14646332008-08-10 11:01:53 +00005086- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5087 menu entries were not deleted.
5088
Brett Cannon83e81842008-08-09 23:30:55 +00005089- Copied the implementation of reduce() to _functools.reduce() to have a
5090 version that did not raise a DeprecationWarning under -3.
5091
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005092- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5093 a MemoryError rather than silently stop the iteration.
5094
Guido van Rossum59ce9012008-08-09 14:55:34 +00005095- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5096 to _sre.compile() will now be rejected. This should not affect anybody
5097 since the re.compile() function never generates invalid re-bytecode.
5098
Skip Montanaroa032bf42008-08-08 22:52:51 +00005099- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5100 upon first access it can be automatically initialized from the csv file if
5101 it wasn't initialized during instantiation.
5102
Brett Cannon3aa2a492008-08-06 22:28:09 +00005103- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5104 the reload() built-in has been removed.
5105
Brett Cannon7e30b672008-08-04 21:52:25 +00005106- Changed code in the following modules/packages to remove warnings raised

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005174Core and Builtins
5175-----------------
5176
Georg Brandl3e483f62008-07-16 22:57:41 +00005177- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5178 its methods now allow for items objects that can be converted to
5179 an integer using operator.index().
5180
Mark Dickinson64b7e502008-07-16 09:40:03 +00005181- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5182 produced a ValueError instead of giving the correct float.
5183
Eric Smitha5fa5a22008-07-16 00:11:49 +00005184- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5185 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5186
Mark Dickinson7103aa42008-07-15 19:08:33 +00005187- Issue #3008: the float type has a new instance method 'float.hex'
5188 and a new class method 'float.fromhex' to convert floating-point
5189 numbers to and from hexadecimal strings, respectively.
5190
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005191- Issue #2235: __hash__ is once again inherited by default. To allow
5192 collections.Hashable to remain meaningful in the presence of the
5193 default hash implementation (object.__hash__), it is now possible
5194 to explicit block inheritance of hash by setting __hash__=None at
5195 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5196 level.
5197
Nick Coghlanb028f502008-07-13 14:52:36 +00005198- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5199 the parent module cannot be found while performing an absolute import.
5200 This means that an incorrectly defined __package__ attribute will
5201 now only prevent relative imports in that module rather than causing
5202 all imports from that module to fail.
5203
Nick Coghlan14ff9942008-07-08 14:21:42 +00005204- Issue #2517: Allow unicode messages in Exceptions again by correctly
5205 bypassing the instance dictionary when looking up __unicode__ on
5206 new-style classes.

5214 another thread's dictionary.
5215
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005216- Issue #3004: Minor change to slice.indices(): the start and stop
5217 arguments are now treated identically, making the behaviour easier
5218 to describe and understand. For example, slice(None, -10,
5219 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5220 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5221 10, -1).
5222
Georg Brandl278fc502008-07-19 12:46:12 +00005223- Issue #3219: Calling a function with repeated keyword arguments,
5224 f(a=2, a=23), would not cause a syntax error. This was a regression
5225 from 2.4 caused by the switch to the new compiler.

5236 error when they failed.
5237
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005238- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005263- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5264 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005265 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005266 content-length. The problem had been corrected in the 2.4 branch, but never
5267 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005282- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5283 handling is now the same as that of other special attributes like __name__).
5284
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005285- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00005673- On MacOS X it is now possible to install the framework in 64-bit
5674 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005675 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005676
5677 This is controlled by the configure argument ``--with-universal-archs``:
5678
5679 - ``--with-universal-archs=all``: install 4-way universal
5680
5681 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5682
5683 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5684
5685 This option should be used in combination with ``--enable-universalsdk=``.
5686
5687 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

5692
Georg Brandl74a1dea2008-05-28 11:21:39 +00005693- Add ``PyType_Modified()`` as a public API to clear the type cache.
5694
5695- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00005696
5697- The PyString functions have been renamed to PyBytes. A batch of
5698 defines were added so that the linker still sees the original
5699 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005737- Issue #1631171: Re-implement the 'warnings' module in C (the
5738 original Python code has been kept as backup). This will allow for
5739 using the 'warning's machinery in such places as the parser where
5740 use of pure Python code is not possible. Both the ``showarning()``
5741 and ``formatwarning()`` gain an optional 'line' argument which is
5742 not called by default for backwards-compatibility reasons. Setting
5743 ``warnings.showwarning()`` to an implementation that lacks support
5744 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005786- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005787 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005807- Issue #2550: The approach used by client/server code for obtaining
5808 ports to listen on in network-oriented tests has been refined in an
5809 effort to facilitate running multiple instances of the entire
5810 regression test suite in parallel without issue.
5811 test_support.bind_port() has been fixed such that it will always
5812 return a unique port -- which wasn't always the case with the
5813 previous implementation, especially if socket options had been set
5814 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5815 new implementation of bind_port() will actually raise an exception
5816 if it is passed an AF_INET/SOCK_STREAM socket with either the
5817 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5818 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5819 the socket it's been passed. This currently only applies to
5820 Windows. This option prevents any other sockets from binding to the
5821 host/port we've bound to, thus removing the possibility of the
5822 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5823 when a second SOCK_STREAM socket binds and accepts to a host/port
5824 that's already been bound by another socket. The optional preferred
5825 port parameter to bind_port() has been removed. Under no
5826 circumstances should tests be hard coding ports!
5827
5828 test_support.find_unused_port() has also been introduced, which will
5829 pass a temporary socket object to bind_port() in order to obtain an
5830 unused port. The temporary socket object is then closed and
5831 deleted, and the port is returned. This method should only be used
5832 for obtaining an unused port in order to pass to an external program
5833 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5834 a parameter to a server-oriented class that doesn't give you direct
5835 access to the underlying socket used.
5836
5837 Finally, test_support.HOST has been introduced, which should be used
5838 for the host argument of any relevant socket calls (i.e. bind and
5839 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005840
5841 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005842 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005843 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5844 test_asynchat and test_socket_ssl.
5845
Georg Brandl3ee81df2008-05-17 18:14:43 +00005846 It is now possible for multiple instances of the regression test
5847 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006126- Added the future_builtins module, which contains hex() and oct().
6127 These are the PEP 3127 version of these functions, designed to be
6128 compatible with the hex() and oct() builtins from Python 3.0. They
6129 differ slightly in their output formats from the existing, unchanged
6130 Python 2.6 builtins. The expected usage of the future_builtins
6131 module is:
6132 from future_builtins import hex, oct
6133
Eric Smith7ef40bf2008-02-20 23:34:22 +00006134- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6135 exponents for exponents with absolute value < 100. Follows C99
6136 standard. This is a change on Windows, which would use 3 digits.
6137 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6138 so that any alterations it does to the resulting string will be
6139 available in stringlib/formatter.h (for float.__format__).
6140
Eric Smith5a3c1352008-02-19 13:21:56 +00006141- Implemented PEP 3101, Advanced String Formatting. This adds a new
6142 builtin format(); a format() method for str and unicode; a
6143 __format__() method to object, str, unicode, int, long, float, and
6144 datetime; the class string.Formatter; and the C API
6145 PyObject_Format().
6146
Georg Brandl3ee81df2008-05-17 18:14:43 +00006147- Fixed several potential crashes, all caused by specially crafted
6148 __del__ methods exploiting objects in temporarily inconsistent
6149 state.

6160 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006161
Georg Brandl3ee81df2008-05-17 18:14:43 +00006162- Issue #2045: Fix an infinite recursion triggered when printing a
6163 subclass of collections.defaultdict, if its default_factory is set
6164 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006165
Christian Heimesf75dbef2008-02-08 00:11:31 +00006166- Fixed a minor memory leak in dictobject.c. The content of the free
6167 list was not freed on interpreter shutdown.
6168
Georg Brandl21e99f42010-03-07 15:23:59 +00006169- Limit free list of method and built-in function objects to 256

6173 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006174 to compact the internal free lists of pre-allocted ints and floats.
6175
Georg Brandl3ee81df2008-05-17 18:14:43 +00006176- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6177 calls. Python expected the return type int but the fork familie
6178 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006189- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6190 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006191
Georg Brandl3ee81df2008-05-17 18:14:43 +00006192- Patch #1473257: generator objects gain a gi_code attribute. This is
6193 the same object as the func_code attribute of the function that
6194 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006195
Georg Brandl3ee81df2008-05-17 18:14:43 +00006196- Issue #1920: "while 0" statements were completely removed by the
6197 compiler, even in the presence of an "else" clause, which is
6198 supposed to be run when the condition is false. Now the compiler
6199 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006200
Guido van Rossumeead05f2008-01-24 18:21:02 +00006201- A few crashers fixed: weakref_in_del.py (issue #1377858);
6202 loosing_dict_ref.py (issue #1303614, test67.py);
6203 borrowed_ref_[34].py (not in tracker).
6204
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006205- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006206 suppressed while an extension is loaded by calling SetErrorMode in
6207 dynload_win.c. The error is still reported properly.
6208
Georg Brandl3ee81df2008-05-17 18:14:43 +00006209- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006210 several extension methods and modules do not work without unicode
6211 support.
6212
Georg Brandl26543b12008-01-21 18:36:51 +00006213- Issue #1882: when compiling code from a string, encoding cookies in the
6214 second line of code were not always recognized correctly.
6215
Georg Brandl14404b62008-01-19 19:27:05 +00006216- Issue #1679: "0x" was taken as a valid integer literal.
6217
Georg Brandl6caad7d2008-01-26 14:19:22 +00006218- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006219 added.
6220
Christian Heimesc94e2b52008-01-14 04:13:37 +00006221- sys.float_info / PyFloat_GetInfo: The floating point information
6222 object was converted from a dict to a specialized structseq object.
6223
Georg Brandl3ee81df2008-05-17 18:14:43 +00006224- Patch #1816: Added sys.flags structseq. It exposes the status of
6225 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006226
Georg Brandl3ee81df2008-05-17 18:14:43 +00006227- Objects/structseq.c: Implemented new structseq representation. The
6228 patch makes structseqs (e.g. the return value of os.stat) more
6229 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006230
Georg Brandl3ee81df2008-05-17 18:14:43 +00006231- Patch #1700288: added a type attribute cache that caches method
6232 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006233
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006234- Bug #1776: __import__() no longer accepts filenames on any platform.
6235 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006236
Georg Brandlaed6c662008-01-07 17:25:53 +00006237- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6238
Georg Brandl3ee81df2008-05-17 18:14:43 +00006239- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6240 envvar and sys.dont_write_bytecode attribute. All these can be set
6241 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006242
Georg Brandl3ee81df2008-05-17 18:14:43 +00006243- Improve some exception messages when Windows fails to load an
6244 extension module. Now we get for example '%1 is not a valid Win32
6245 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006246
Georg Brandl3ee81df2008-05-17 18:14:43 +00006247- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00006248
Georg Brandl3ee81df2008-05-17 18:14:43 +00006249- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6250 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006251
Christian Heimes0a8143f2007-12-18 23:22:54 +00006252- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006253 and INF. float("nan"), float("inf") and float("-inf") now work on
6254 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006255
Georg Brandl3ee81df2008-05-17 18:14:43 +00006256- Compiler now generates simpler and faster code for dictionary
6257 literals. The oparg for BUILD_MAP now indicates an estimated
6258 dictionary size. There is a new opcode, STORE_MAP, for adding
6259 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006260
Georg Brandl3ee81df2008-05-17 18:14:43 +00006261- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00006262
Georg Brandl3ee81df2008-05-17 18:14:43 +00006263- Issue #1620: New property decorator syntax was modifying the
6264 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006265
Georg Brandl3ee81df2008-05-17 18:14:43 +00006266- Issue #1538: Avoid copying string in split/rsplit if the split char
6267 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006268
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006269- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006270 SystemError.
6271
Nick Coghlanef01d822007-12-03 12:55:17 +00006272- PEP 366: Allow explicit relative imports when executing modules
6273 inside packages with the -m switch via a new module level
6274 __package__ attribute.
6275
Georg Brandl3ee81df2008-05-17 18:14:43 +00006276- Issue #1402: Fix a crash on exit, when another thread is still
6277 running, and if the deallocation of its frames somehow calls the
6278 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006279

6281
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00006282- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006283 attribute of an empty cell object.
6284
Georg Brandl3ee81df2008-05-17 18:14:43 +00006285- Issue #1460: The utf-7 incremental decoder did not accept truncated
6286 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006287
Georg Brandl3ee81df2008-05-17 18:14:43 +00006288- Patch #1739468: Directories and zipfiles containing a __main__.py
6289 file can now be directly executed by passing their name to the
6290 interpreter. The directory/zipfile is automatically inserted as the
6291 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006292
Georg Brandl3ee81df2008-05-17 18:14:43 +00006293- Issue #1265: Fix a problem with sys.settrace, if the tracing
6294 function uses a generator expression when at the same time the
6295 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006296
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006297- sets and frozensets now have an isdisjoint() method.
6298
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006299- optimize the performance of builtin.sum().
6300
Neal Norwitz44f326e2007-10-05 05:29:17 +00006301- Fix warnings found by the new version of the Coverity checker.
6302
Georg Brandl21e99f42010-03-07 15:23:59 +00006303- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006304 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6305 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006306
Georg Brandl3ee81df2008-05-17 18:14:43 +00006307- Issue #1686386: Tuple's tp_repr did not take into account the
6308 possibility of having a self-referential tuple, which is possible
6309 from C code. Nor did object's tp_str consider that a type's tp_str
6310 could do something that could lead to an inifinite recursion.
6311 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6312 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006313
Georg Brandl3ee81df2008-05-17 18:14:43 +00006314- Issue #1164: It was possible to trigger deadlock when using the
6315 'print' statement to write to a file since the GIL was not released
6316 as needed. Now PyObject_Print() does the right thing along with
6317 various tp_print implementations of the built-in types and those in
6318 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006319
Georg Brandl3ee81df2008-05-17 18:14:43 +00006320- Issue #1147: Exceptions were directly allowing string exceptions in
6321 their throw() method even though string exceptions no longer
6322 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006323
Georg Brandl3ee81df2008-05-17 18:14:43 +00006324- Issue #1096: Prevent a segfault from getting the repr of a very
6325 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006326
Brett Cannon1e534b52007-09-07 04:18:30 +00006327- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006328 PyObject_Call() never calling back out to Python code to trigger
6329 recursion depth updates/checks. Required the creation of a static
6330 RuntimeError instance in case normalizing an exception put the
6331 recursion check value past its limit. Fixes crashers
6332 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006333
Georg Brandl3ee81df2008-05-17 18:14:43 +00006334- Patch #1031213: Decode source line in SyntaxErrors back to its
6335 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00006337- Patch #1673759: add a missing overflow check when formatting floats
6338 with %G.
6339
Georg Brandl3ee81df2008-05-17 18:14:43 +00006340- Prevent expandtabs() on string and unicode objects from causing a
6341 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006342

Georg Brandla5ea6892007-06-01 11:33:33 +00006346
Neal Norwitz0ac60192007-05-27 04:08:54 +00006347- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006348 __*__ attributes. (Some already existed, e.g., __doc__ and
6349 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006350
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006351- Add -3 option to the interpreter to warn about features that are
6352 deprecated and will be changed/removed in Python 3.0.
6353
Georg Brandl2134e752007-05-21 20:34:16 +00006354- Patch #1686487: you can now pass any mapping after '**' in function
6355 calls.
6356
Collin Winter62903052007-05-18 23:11:24 +00006357- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006358 "except E as target:". This is to provide forwards compatibility
6359 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006360
Brett Cannon229cee22007-05-05 01:34:02 +00006361- Deprecate BaseException.message as per PEP 352.
6362
Georg Brandl3ee81df2008-05-17 18:14:43 +00006363- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006364 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006365
Vinay Sajip8549ce32007-05-06 17:53:37 +00006366- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006367 setting a plain string, ie don't expand to single letter identifiers.
6368
Raymond Hettinger13936692007-04-11 18:40:58 +00006369- Request #1191699: Slices can now be pickled.
6370
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006371- Request #1193128: str.translate() now allows a None argument for
6372 translations that only remove characters without re-mapping the
6373 remaining characters.
6374
Georg Brandl5cb76c12007-03-21 09:00:39 +00006375- Patch #1682205: a TypeError while unpacking an iterable is no longer
6376 masked by a generic one with the message "unpack non-sequence".
6377
Neal Norwitzaa754b72007-03-21 06:39:48 +00006378- Remove unused file Python/fmod.c.
6379
Guido van Rossum143b5642007-03-23 04:58:42 +00006380- Bug #1683368: The object.__init__() and object.__new__() methods are
6381 now stricter in rejecting excess arguments. The only time when
6382 either allows excess arguments is when it is not overridden and the
6383 other one is. For backwards compatibility, when both are
6384 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006385 warning later). Also, type.__init__() insists on the same signature
6386 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006387
Georg Brandl3ee81df2008-05-17 18:14:43 +00006388- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6389 object to complex using its __complex__() method before falling back
6390 to the __float__() method. Therefore, the functions in the cmath
6391 module now can operate on objects that define a __complex__()
6392 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006393
Georg Brandl3ee81df2008-05-17 18:14:43 +00006394- Patch #1623563: allow __class__ assignment for classes with
6395 __slots__. The old and the new class are still required to have the
6396 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006397
Georg Brandl3ee81df2008-05-17 18:14:43 +00006398- Patch #1642547: Fix an error/crash when encountering syntax errors
6399 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006401- Patch #1462488: Python no longer segfaults when
6402 ``object.__reduce_ex__()`` is called with an object that is faking
6403 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006404
Georg Brandl3ee81df2008-05-17 18:14:43 +00006405- Patch #1680015: Don't modify __slots__ tuple if it contains an
6406 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00006408- Patch #1444529: the builtin compile() now accepts keyword arguments.
6409
Georg Brandl7b9c5552007-03-12 14:30:05 +00006410- Bug #1678647: write a newline after printing an exception in any
6411 case, even when converting the value to a string failed.
6412
Georg Brandl871f1bc2007-03-12 13:17:36 +00006413- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006414 its argument, if it exists. If not, it will work like before. This
6415 allows customizing the output of dir() in the presence of a
6416 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006417
Collin Winter276887b2007-03-12 16:11:39 +00006418- Patch #922167: Python no longer segfaults when faced with infinitely
6419 self-recursive reload() calls (as reported by bug #742342).
6420
Georg Brandl3ee81df2008-05-17 18:14:43 +00006421- Patch #1675981: remove unreachable code from ``type.__new__()``
6422 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00006423
Georg Brandl3ee81df2008-05-17 18:14:43 +00006424- Patch #1491866: change the complex() constructor to allow
6425 parthensized forms. This means complex(repr(x)) now works instead of
6426 raising a ValueError.

Georg Brandl4e933132006-09-06 20:05:58 +00006531- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006549 generator expressions (x for x, in ... ) works again. Fixing this
6550 problem required changing the .pyc magic number. This means that

6937 ".cpp" too.
6938
Facundo Batistad918a652007-04-24 13:54:38 +00006939- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006940 the client's request was successfully received, understood, and
6941 accepted. Now in these cases no error is raised in urllib (issue
6942 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00006943

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006950- Added a timeout parameter to the constructor of other protocols
6951 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6952 work started with create_connection() and timeout in httplib, and
6953 closes patch #723312.
6954
Vinay Sajip8549ce32007-05-06 17:53:37 +00006955- Patch #1676823: Added create_connection() to socket.py, which may be
6956 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006957 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006958
Martin v. Löwis0af33882007-03-23 13:27:15 +00006959- Bug #978833: Revert r50844, as it broke _socketobject.dup.

6979
Georg Brandlf66b6032007-03-14 08:27:52 +00006980- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006981 AttributeError instead of an IOError when the server's response
6982 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006983
Georg Brandl3ee81df2008-05-17 18:14:43 +00006984- Patch #957650: "%var%" environment variable references are now
6985 properly expanded in ntpath.expandvars(), also "~user" home
6986 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00006987
Georg Brandl3ee81df2008-05-17 18:14:43 +00006988- Patch #1429539: pdb now correctly initializes the __main__ module
6989 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006990 correctly now.
6991
Georg Brandlbad6f192007-03-13 21:32:56 +00006992- The nonobvious commands.getstatus() function is now deprecated.

6998
Georg Brandl3ee81df2008-05-17 18:14:43 +00006999- Patch #1530482: add pydoc.render_doc() which returns the
7000 documentation for a thing instead of paging it to stdout, which
7001 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007002
Georg Brandl3ee81df2008-05-17 18:14:43 +00007003- Patch #1533909: the timeit module now accepts callables in addition

7010 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00007012- Patch #1581073: add a flag to textwrap that prevents the dropping of

7014
Georg Brandl92a6bae2007-03-13 17:43:32 +00007015- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007016 are set for invalid interpolation sequences that would lead to
7017 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007018

7031
Georg Brandl94fe3f52007-03-13 09:32:11 +00007032- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00007033 field names in its exception message if you try to write a record
7034 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00007052

7060 returned string up to the first NUL character.
7061

7071
Georg Brandl3ee81df2008-05-17 18:14:43 +00007072- unittest now verifies more of its assumptions. In particular,
7073 TestCase and TestSuite subclasses (not instances) are no longer
7074 accepted in TestSuite.addTest(). This should cause no
7075 incompatibility since it never made sense with ordinary subclasses
7076 -- the failure just occurred later, with a more cumbersome
7077 exception.

7086 given a unicode argument and os.listdir() returns unicode filenames.
7087
Georg Brandl3ee81df2008-05-17 18:14:43 +00007088- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00007466 time so that opening a database previously created with the DB_DUP
7467 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7468 opens. Specifically: dictionary assignment to a DB object will
7469 replace all values for a given key when the database allows
7470 duplicate values. DB users should use DB.put(k, v) when they want
7471 to store duplicates; not DB[k] = v.

7478 characters with ASCII value less than 32. Also, it correctly quotes
7479 dots only if they occur on a single line, as opposed to the previous
7480 behavior of quoting dots if they are the second character of any
7481 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007482
