13-----------------
14
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +000015- Issue #8748: Fix two issues with comparisons between complex and integer
16 objects. (1) The comparison could incorrectly return True in some cases
17 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
18 (2) The comparison raised an OverflowError for large integers, leading
19 to unpredictable exceptions when combining integers and complex objects
20 in sets or dicts.
21
Mark Dickinson81336372010-05-30 12:12:25 +000022- Issue #5211: Implicit coercion for the complex type is now completely
23 removed. (Coercion for arithmetic operations was already removed in 2.7
24 alpha 4, but coercion for rich comparisons was accidentally left in.)
25
Victor Stinnerc49dfcc2010-05-25 22:30:32 +000026- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
27 and error handler, instead of writing to the C stderr file in utf-8
28
Georg Brandlfee0f442010-05-22 21:26:21 +000029- Issue #7902: When using explicit relative import syntax, don't try implicit
30 relative import semantics.

Georg Brandlfee0f442010-05-22 21:26:21 +000032- Issue #7079: Fix a possible crash when closing a file object while using it
33 from another thread. Patch by Daniel Stutzbach.

Ronald Oussoren27c72e92010-06-02 03:47:14 +000035- Issue #8868: Fix that ensures that python scripts have access to the
36 Window Server again in a framework build on MacOSX 10.5 or earlier.

40
Georg Brandlfee0f442010-05-22 21:26:21 +000041- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
42 of the interpreter to set sys.argv without also modifying sys.path. This
43 helps fix `CVE-2008-5983
Antoine Pitrou6a265602010-05-21 17:12:38 +000044 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

50 mistake.
51
R. David Murray52dcd452010-06-02 22:03:15 +000052- Issue #1368247: set_charset (and therefore MIMEText) now automatically
53 encodes a unicode _payload to the output_charset.
54
Alexander Belopolsky9292ee02010-05-27 20:55:27 +000055- Issue #7150: Raise OverflowError if the result of adding or subtracting

109
Georg Brandlfee0f442010-05-22 21:26:21 +0000110- On darwin, ``test_site`` assumed that a framework build was being used,

Georg Brandlfee0f442010-05-22 21:26:21 +0000129- Issue #1533: Fix inconsistency in range function argument processing: any
130 non-float non-integer argument is now converted to an integer (if possible)
131 using its __int__ method. Previously, only small arguments were treated this
132 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +0000141 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +0000142 benefit compared to the dynamic memory allocation fallback. Patch by
143 Charles-François Natali.

184 operation raises multiple signals and more than one of those signals is
185 trapped, the specification determines the order in which the signals should be
186 handled. In many cases this order wasn't being followed, leading to the wrong

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000332 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

354Core and Builtins
355-----------------
356
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000357- Issue #7301: Add environment variable $PYTHONWARNINGS.
358
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000359- Issue #8329: Don't return the same lists from select.select when no fds are
360 changed.
361
Georg Brandlfee0f442010-05-22 21:26:21 +0000362- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000363 on 64-bit machines. The shift count for either left or right shift is
364 permitted to be up to sys.maxsize.
365
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000366- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000370- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
371
Georg Brandlfee0f442010-05-22 21:26:21 +0000372- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
373 with a non-empty format string. This is an effort to future-proof user
374 code. If a derived class does not currently implement __format__ but later
375 adds its own __format__, it would most likely break user code that had
376 supplied a format string. This will be changed to a DeprecationWaring in
377 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000378
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000379- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000404- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000405 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

409
Georg Brandlfee0f442010-05-22 21:26:21 +0000410- Issue #8257: The Decimal construct now accepts a float instance directly,
411 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000412
413 >>> Decimal(1.1)
414 Decimal('1.100000000000000088817841970012523233890533447265625')
415
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000416- collections.Counter() now supports a subtract() method.
417
Georg Brandlfee0f442010-05-22 21:26:21 +0000418- The functools module now has a total_ordering() class decorator to simplify
419 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000420
Georg Brandlfee0f442010-05-22 21:26:21 +0000421- The functools module also adds cmp_to_key() as a tool to transition old-style

Raymond Hettingera551f312010-04-04 18:34:45 +0000423
Georg Brandlfee0f442010-05-22 21:26:21 +0000424- Issue #8294: The Fraction constructor now accepts Decimal and float instances
425 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000426
Georg Brandlfee0f442010-05-22 21:26:21 +0000427- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
428 InvalidOperation instead of returning False. (Comparisons involving a quiet
429 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
430 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000431
Georg Brandlfee0f442010-05-22 21:26:21 +0000432- Issue #2531: Comparison operations between floats and Decimal instances now
433 return a result based on the numeric values of the operands; previously they
434 returned an arbitrary result based on the relative ordering of id(float) and
435 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000436
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000437- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000438 argument `-` which tells it to read files to compile from stdin. Each line is
439 read on demand and the named file is compiled immediately. (Original patch by
440 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000441

Georg Brandlfee0f442010-05-22 21:26:21 +0000449- Comparisons using one of <, <=, >, >= between a complex instance and a
450 Fractions instance now raise TypeError instead of returning True/False. This
451 makes Fraction <=> complex comparisons consistent with int <=> complex, float
452 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000453

465 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000466
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000467- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

821 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
822 numeric strings corresponding to subnormal values,
823 (3) a memory leak for some values large enough to cause overflow, and
824 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000859- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000860 file position when calling `truncate()`. It would previously change the file
861 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000862 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Benjamin Petersone06f7112010-01-28 02:15:02 +0000864- UserDict is now a new-style class.
865
Georg Brandlba83f822010-03-14 09:50:54 +0000866- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
867 class used to represent files stored inside an archive. The new
868 implementation is significantly faster and can be wrapped in a
869 ``io.BufferedReader`` object for more speedups. It also solves an issue
870 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
871 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +0000880
Georg Brandlba83f822010-03-14 09:50:54 +0000881- Issue #7748: Since unicode values are supported for some metadata options in
882 Distutils, the DistributionMetadata get_* methods will now return an utf-8
883 encoded string for them. This ensures that the upload and register commands
884 send the correct values to PyPI without any error.

960
Georg Brandlba83f822010-03-14 09:50:54 +0000961- The ``__complex__()`` method is now looked up on the class of instances to
962 make it consistent with other special methods.

966
Mark Dickinson1b34d252010-01-01 17:27:30 +0000967- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000968 DeprecationWarning when passed a float argument where an integer was expected.
969 These functions and methods now raise TypeError instead. The majority of the
970 effects of this change are in the extension modules, but some core functions
971 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
972 and many unicode/str methods.

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

Georg Brandlba83f822010-03-14 09:50:54 +00001155- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1156 decimal string that's guaranteed to round back to x under correct rounding
1157 (with round-half-to-even rounding mode). Previously it gave a string based on
1158 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1159 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1160 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001161
Georg Brandlba83f822010-03-14 09:50:54 +00001162- Issue #7117: On almost all platforms: float-to-string and string-to-float
1163 conversions within Python are now correctly rounded. Places these conversions
1164 occur include: str for floats and complex numbers; the float and complex
1165 constructors; old-style and new-style numeric formatting; serialization and
1166 deserialization of floats and complex numbers using marshal, pickle and json;
1167 parsing of float and imaginary literals in Python code; Decimal-to-float
1168 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001169
Georg Brandlba83f822010-03-14 09:50:54 +00001170 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1171 providing correctly-rounded strtod and dtoa C functions. This code is
1172 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1173 the C compiler. There may be a small number of platforms on which correct
1174 operation of this code cannot be guaranteed, so the code is not used: notably,
1175 this applies to platforms where the C double format is not IEEE 754 binary64,
1176 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1177 and Python's configure script is unable to determine how to change the FPU
1178 precision. On these platforms conversions use the platform strtod and dtoa,
1179 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001181- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1182 uses the correctly-rounded string <-> float conversions described above (when
1183 available), and so produces correctly rounded results that will display nicely
1184 under the float repr. There are two related small changes: (1) round now
1185 accepts any class with an ``__index__()`` method for its second argument (but
1186 no longer accepts floats for the second argument), and (2) an excessively
1187 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1188 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001335- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1336 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1337 but with at least one decimal point and with a default precision
1338 of 12. Previously, the behavior the same but with a default precision of 6.
1339 This more closely matches ``str()``, and reduces surprises when adding
1340 alignment flags to the empty presentation type. This also affects the new
1341 complex.__format__ in the same way.
1342

Georg Brandlba83f822010-03-14 09:50:54 +00001481- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1482 existing .py counterpart, override the co_filename attributes of all code

1538
Georg Brandlba83f822010-03-14 09:50:54 +00001539- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1540 file objects with closefd=False. The file descriptor is still kept open but
1541 the file object behaves like a closed file. The ``FileIO`` object also got a
1542 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001562- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001565- On windows, ``os.chdir()`` given unicode was not working if
1566 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1567 this code path is really executed because I cannot move to such directory on
1568 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001570- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1571 element is temporarily replaced with an equivalent frozenset. But the
1572 eventual KeyError would always report the empty ``frozenset()`` as the missing
1573 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001593- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1594 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1595 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1596 of using the replace error handler in PyUnicode_DecodeUTF8().
1597
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001598- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001601- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1603 gives improved memory leak detection when running under Valgrind, while taking
1604 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00002136- Issue #5679: The methods unittest.TestCase.addCleanup and doCleanups were
2137 added. addCleanup allows you to add cleanup functions that will be called
Michael Foord07ef4872009-05-02 22:43:34 +00002138 unconditionally (after setUp if setUp fails, otherwise after tearDown). This
2139 allows for much simpler resource allocation and deallocation during tests.

Georg Brandlba83f822010-03-14 09:50:54 +00002153- Issue #5663: Better failure messages for unittest asserts. Default assertTrue
Michael Foord345b2fe2009-04-02 03:20:38 +00002154 and assertFalse messages are now useful. TestCase has a longMessage attribute.
2155 This defaults to False, but if set to True useful error messages are shown in
2156 addition to explicit messages passed to assert methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002827 leak-chasing test runs give sensible results. The previous method of reaping
2828 threads could return successfully while some Thread objects were still
2829 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002846- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2847 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002848 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2849 the tests if DISPLAY is defined but can't be used.

2855 import both normal and optimised versions of modules. test_heapq and
2856 test_warnings have been adjusted to use it, tests for other modules with both
2857 C and Python implementations in the stdlib can be adjusted to use it over
2858 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002866- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2867 should cause a test to be skipped are now done using import_module from test
2868 support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002971- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2972 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2973 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2974 ``printf`` function, whereas PyString_FromFormat has an independent
2975 implementation and uses "%zd" on all platforms for size_t values.
2976 This makes a difference on win64, where ``printf`` needs "%Id" to display
2977 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002979- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2983 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00002996- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002997 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2998 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2999 when given a tuple of classes as second argument, were looking up
3000 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3001 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003140What's New in Python 2.6 beta 3?
3141================================
3142
Barry Warsaw07a4a382008-08-21 01:15:08 +00003143*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003144
3145Core and Builtins
3146-----------------
3147
Guido van Rossumf8402962008-08-20 15:01:50 +00003148- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3149 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3150 extensions do not automatically benefit from the class attribute
3151 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3152 to their tp_flags field if they care. This is a backwards
3153 compatibility feature; in 3.0, all types will use the cache by
3154 default.
3155
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003156- Keyword arguments can now follow starred arguments. (``f(a, *args,
3157 keyword=23)`` is now valid syntax.)
3158
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003159- ctypes function pointers that are COM methods have a boolean True
3160 value again.
3161
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003162- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3163 by denying s# to parse objects that have a releasebuffer procedure,
3164 and introducing s*.
3165
Georg Brandl1e13ea92008-08-11 09:07:59 +00003166- Issue #3537: Fix an assertion failure when an empty but presized dict
3167 object was stored in the freelist.
3168
Mark Dickinsonb6467572008-08-04 21:30:09 +00003169- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3170 ValueError consistently across platforms.
3171
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003172- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3173 (64bit Unix, for example), unichr() would truncate its argument and return
3174 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3175
Neal Norwitze7d8be82008-07-31 17:17:14 +00003176- Apply security patches from Apple.
3177
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003178- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3179 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3180
Antoine Pitrou92f82162008-07-25 22:22:08 +00003181- Issue #1819: function calls with several named parameters are now on
3182 average 35% faster (as measured by pybench).
3183
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003184- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3185 the python debugger steps into a class statement: the free variables (local
3186 variables defined in an outer scope) would be deleted from the outer scope.
3187
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003188- Issue #2620: Overflow checking when allocating or reallocating memory
3189 was not always being done properly in some python types and extension
3190 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3191 all been updated to perform better checks and places in the code that
3192 would previously leak memory on the error path when such an allocation
3193 failed have been fixed.
3194
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003195Library
3196-------
3197
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003198- Issue #3612: Added some missing basic types in ctypes.wintypes.
3199
Benjamin Petersone977ad42008-08-20 01:42:01 +00003200- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3201 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3202
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003203- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3204 version reported by these tools does not necessarily follow the python
3205 version numbering scheme, so the module is less strict when parsing it.
3206
Nick Coghlanf70385a2008-08-18 12:42:46 +00003207- Issue #2235: Added Py3k warnings for types which will become unhashable
3208 under the stricter __hash__ inheritance rules in 3.0. Several types
3209 which did not meet the rules for hash invariants and were already
3210 unhashable in 3.0 have now been explicitly flagged as unhashable in
3211 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3212 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3213
Brett Cannon88f801d2008-08-18 00:46:22 +00003214- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3215 imported into the module but exposed as part of the module's API.
3216
Brett Cannon7b96f072008-08-18 00:41:11 +00003217- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3218
Brett Cannon46225e72008-08-18 00:36:52 +00003219- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3220
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003221- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3222
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003223- Issue #3575: Incremental decoder's decode function now takes bytearray
3224 by using 's*' instead of 't#'.
3225
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003226- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003227 fails unicode conversion on 2nd parameter. (windows only)
3228
Facundo Batista94f243a2008-08-17 03:38:39 +00003229- Issue 2464. urllib2 now supports a malformation in the URL received
3230 in a redirect.
3231
Brett Cannonabe423e2008-08-16 21:47:07 +00003232- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003233 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003234
Facundo Batistaeb90b782008-08-16 14:44:07 +00003235- Issue #2776: fixed small issue when handling an URL with double slash
3236 after a 302 response in the case of not going through a proxy.
3237
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003238- Issue #2676: in the email package, content-type parsing was hanging on
3239 pathological input because of quadratic or exponential behaviour of a
3240 regular expression.
3241
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003242- Issue #3476: binary buffered reading through the new "io" library is now
3243 thread-safe.
3244
Brett Cannonbf3157b2008-08-14 05:00:03 +00003245- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3246 since mimetools itself is deprecated. Because modules are cached, all
3247 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3248
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003249- Issue #3134: shutil referenced undefined WindowsError symbol.
3250
Robert Schuppenies14646332008-08-10 11:01:53 +00003251- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3252 menu entries were not deleted.
3253
Brett Cannon83e81842008-08-09 23:30:55 +00003254- Copied the implementation of reduce() to _functools.reduce() to have a
3255 version that did not raise a DeprecationWarning under -3.
3256
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003257- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3258 a MemoryError rather than silently stop the iteration.
3259
Guido van Rossum59ce9012008-08-09 14:55:34 +00003260- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3261 to _sre.compile() will now be rejected. This should not affect anybody
3262 since the re.compile() function never generates invalid re-bytecode.
3263
Skip Montanaroa032bf42008-08-08 22:52:51 +00003264- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3265 upon first access it can be automatically initialized from the csv file if
3266 it wasn't initialized during instantiation.
3267
Brett Cannon3aa2a492008-08-06 22:28:09 +00003268- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3269 the reload() built-in has been removed.
3270
Brett Cannon7e30b672008-08-04 21:52:25 +00003271- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003272 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003279- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3280 raised an AttributeError.
3281
Benjamin Peterson01a24322008-07-28 23:35:27 +00003282- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003283 asking for a specific length. This problem only affected files opened
3284 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003285
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003286- Issue #3449: Update decimal module to use most recent specification
3287 (v. 1.68) and tests (v. 2.58) from IBM.
3288
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003289- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

3297
3298- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3299 invalid arguments.
3300
3301- Issue #3302: Fix several crashes when calling locale's gettext functions
3302 with None arguments.
3303
3304- Issue #3389: Allow resolving dotted names for handlers in logging
3305 configuration files.
3306
3307- Deprecate the sunaudio module for removal in Python 3.0.
3308
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003309- Issue #3394: zipfile.writestr sets external attributes when passed a
3310 file name rather than a ZipInfo instance, so files are extracted with
3311 mode 0600 rather than 000 under Unix.
3312
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003313- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3314 argument in python 2.5, this broke code that subclassed Popen to include its
3315 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003325- Issue #2235: the C API function PyObject_HashNotImplemented and its
3326 interaction with the tp_hash slot (added in 2.6b2) are now documented
3327
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003328- Issue #643841: The language reference now provides more detailed
3329 coverage of the lookup process for special methods. The disclaimers
3330 regarding lack of coverage of new-style classes have also been
3331 removed, since the coverage is now fairly reasonable.

3336
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003337*Release date: 17-Jul-2008*

3340-----------------
3341
Georg Brandl3e483f62008-07-16 22:57:41 +00003342- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3343 its methods now allow for items objects that can be converted to
3344 an integer using operator.index().
3345
Mark Dickinson64b7e502008-07-16 09:40:03 +00003346- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3347 produced a ValueError instead of giving the correct float.
3348
Eric Smitha5fa5a22008-07-16 00:11:49 +00003349- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3350 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3351
Mark Dickinson7103aa42008-07-15 19:08:33 +00003352- Issue #3008: the float type has a new instance method 'float.hex'
3353 and a new class method 'float.fromhex' to convert floating-point
3354 numbers to and from hexadecimal strings, respectively.
3355
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003356- Issue #2235: __hash__ is once again inherited by default. To allow
3357 collections.Hashable to remain meaningful in the presence of the
3358 default hash implementation (object.__hash__), it is now possible
3359 to explicit block inheritance of hash by setting __hash__=None at
3360 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3361 level.
3362
Nick Coghlanb028f502008-07-13 14:52:36 +00003363- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3364 the parent module cannot be found while performing an absolute import.
3365 This means that an incorrectly defined __package__ attribute will
3366 now only prevent relative imports in that module rather than causing
3367 all imports from that module to fail.
3368
Nick Coghlan14ff9942008-07-08 14:21:42 +00003369- Issue #2517: Allow unicode messages in Exceptions again by correctly
3370 bypassing the instance dictionary when looking up __unicode__ on
3371 new-style classes.
3372
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003373- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3374 set to a custom object whose write() method happens to install
3375 another file in sys.stdout.

3379 another thread's dictionary.
3380
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003381- Issue #3004: Minor change to slice.indices(): the start and stop
3382 arguments are now treated identically, making the behaviour easier
3383 to describe and understand. For example, slice(None, -10,
3384 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3385 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3386 10, -1).
3387
Georg Brandl278fc502008-07-19 12:46:12 +00003388- Issue #3219: Calling a function with repeated keyword arguments,
3389 f(a=2, a=23), would not cause a syntax error. This was a regression
3390 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00003840 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003841
3842 This is controlled by the configure argument ``--with-universal-archs``:
3843

3845
3846 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3847
3848 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3849

3889 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003902- Issue #1631171: Re-implement the 'warnings' module in C (the
3903 original Python code has been kept as backup). This will allow for
3904 using the 'warning's machinery in such places as the parser where
3905 use of pure Python code is not possible. Both the ``showarning()``
3906 and ``formatwarning()`` gain an optional 'line' argument which is
3907 not called by default for backwards-compatibility reasons. Setting
3908 ``warnings.showwarning()`` to an implementation that lacks support
3909 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003972- Issue #2550: The approach used by client/server code for obtaining
3973 ports to listen on in network-oriented tests has been refined in an
3974 effort to facilitate running multiple instances of the entire
3975 regression test suite in parallel without issue.
3976 test_support.bind_port() has been fixed such that it will always
3977 return a unique port -- which wasn't always the case with the
3978 previous implementation, especially if socket options had been set
3979 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3980 new implementation of bind_port() will actually raise an exception
3981 if it is passed an AF_INET/SOCK_STREAM socket with either the
3982 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3983 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3984 the socket it's been passed. This currently only applies to
3985 Windows. This option prevents any other sockets from binding to the
3986 host/port we've bound to, thus removing the possibility of the
3987 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3988 when a second SOCK_STREAM socket binds and accepts to a host/port
3989 that's already been bound by another socket. The optional preferred
3990 port parameter to bind_port() has been removed. Under no
3991 circumstances should tests be hard coding ports!
3992
3993 test_support.find_unused_port() has also been introduced, which will
3994 pass a temporary socket object to bind_port() in order to obtain an
3995 unused port. The temporary socket object is then closed and
3996 deleted, and the port is returned. This method should only be used
3997 for obtaining an unused port in order to pass to an external program
3998 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3999 a parameter to a server-oriented class that doesn't give you direct
4000 access to the underlying socket used.
4001
4002 Finally, test_support.HOST has been introduced, which should be used
4003 for the host argument of any relevant socket calls (i.e. bind and
4004 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004005
4006 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004007 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004008 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4009 test_asynchat and test_socket_ssl.
4010
Georg Brandl3ee81df2008-05-17 18:14:43 +00004011 It is now possible for multiple instances of the regression test
4012 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00004281- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004282 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00004287
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004288- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004289 issue 215555 for a discussion.
4290
Eric Smitha73fbe72008-02-23 03:09:44 +00004291- Added the future_builtins module, which contains hex() and oct().
4292 These are the PEP 3127 version of these functions, designed to be
4293 compatible with the hex() and oct() builtins from Python 3.0. They
4294 differ slightly in their output formats from the existing, unchanged
4295 Python 2.6 builtins. The expected usage of the future_builtins
4296 module is:
4297 from future_builtins import hex, oct
4298
Eric Smith7ef40bf2008-02-20 23:34:22 +00004299- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4300 exponents for exponents with absolute value < 100. Follows C99
4301 standard. This is a change on Windows, which would use 3 digits.
4302 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4303 so that any alterations it does to the resulting string will be
4304 available in stringlib/formatter.h (for float.__format__).
4305
Eric Smith5a3c1352008-02-19 13:21:56 +00004306- Implemented PEP 3101, Advanced String Formatting. This adds a new
4307 builtin format(); a format() method for str and unicode; a
4308 __format__() method to object, str, unicode, int, long, float, and
4309 datetime; the class string.Formatter; and the C API
4310 PyObject_Format().
4311
Georg Brandl3ee81df2008-05-17 18:14:43 +00004312- Fixed several potential crashes, all caused by specially crafted
4313 __del__ methods exploiting objects in temporarily inconsistent
4314 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004315
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004316- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004317 prevent a possible crash: an Abstract Base Class would try to access
4318 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004319
Georg Brandl3ee81df2008-05-17 18:14:43 +00004320- Fixed repr() and str() of complex numbers with infinity or nan as
4321 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004322
Georg Brandl3ee81df2008-05-17 18:14:43 +00004323- Clear all free lists during a gc.collect() of the highest generation
4324 in order to allow pymalloc to free more arenas. Python may give back
4325 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004326
Georg Brandl3ee81df2008-05-17 18:14:43 +00004327- Issue #2045: Fix an infinite recursion triggered when printing a
4328 subclass of collections.defaultdict, if its default_factory is set
4329 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004330
Christian Heimesf75dbef2008-02-08 00:11:31 +00004331- Fixed a minor memory leak in dictobject.c. The content of the free
4332 list was not freed on interpreter shutdown.
4333
Georg Brandl21e99f42010-03-07 15:23:59 +00004334- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004335 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004336
Georg Brandl3ee81df2008-05-17 18:14:43 +00004337- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4338 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004339 to compact the internal free lists of pre-allocted ints and floats.
4340
Georg Brandl3ee81df2008-05-17 18:14:43 +00004341- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4342 calls. Python expected the return type int but the fork familie
4343 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004344
Georg Brandl3ee81df2008-05-17 18:14:43 +00004345- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004354- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4355 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004356
Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- Patch #1473257: generator objects gain a gi_code attribute. This is
4358 the same object as the func_code attribute of the function that
4359 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004360
Georg Brandl3ee81df2008-05-17 18:14:43 +00004361- Issue #1920: "while 0" statements were completely removed by the
4362 compiler, even in the presence of an "else" clause, which is
4363 supposed to be run when the condition is false. Now the compiler
4364 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004365
Guido van Rossumeead05f2008-01-24 18:21:02 +00004366- A few crashers fixed: weakref_in_del.py (issue #1377858);
4367 loosing_dict_ref.py (issue #1303614, test67.py);
4368 borrowed_ref_[34].py (not in tracker).
4369
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004370- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004371 suppressed while an extension is loaded by calling SetErrorMode in
4372 dynload_win.c. The error is still reported properly.
4373
Georg Brandl3ee81df2008-05-17 18:14:43 +00004374- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004375 several extension methods and modules do not work without unicode
4376 support.
4377
Georg Brandl26543b12008-01-21 18:36:51 +00004378- Issue #1882: when compiling code from a string, encoding cookies in the
4379 second line of code were not always recognized correctly.
4380
Georg Brandl14404b62008-01-19 19:27:05 +00004381- Issue #1679: "0x" was taken as a valid integer literal.
4382
Georg Brandl6caad7d2008-01-26 14:19:22 +00004383- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004384 added.
4385
Christian Heimesc94e2b52008-01-14 04:13:37 +00004386- sys.float_info / PyFloat_GetInfo: The floating point information
4387 object was converted from a dict to a specialized structseq object.
4388
Georg Brandl3ee81df2008-05-17 18:14:43 +00004389- Patch #1816: Added sys.flags structseq. It exposes the status of
4390 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004391
Georg Brandl3ee81df2008-05-17 18:14:43 +00004392- Objects/structseq.c: Implemented new structseq representation. The
4393 patch makes structseqs (e.g. the return value of os.stat) more
4394 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004395
Georg Brandl3ee81df2008-05-17 18:14:43 +00004396- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00004408- Improve some exception messages when Windows fails to load an
4409 extension module. Now we get for example '%1 is not a valid Win32
4410 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004418 and INF. float("nan"), float("inf") and float("-inf") now work on
4419 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004420
Georg Brandl3ee81df2008-05-17 18:14:43 +00004421- Compiler now generates simpler and faster code for dictionary
4422 literals. The oparg for BUILD_MAP now indicates an estimated
4423 dictionary size. There is a new opcode, STORE_MAP, for adding
4424 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004453- Patch #1739468: Directories and zipfiles containing a __main__.py
4454 file can now be directly executed by passing their name to the
4455 interpreter. The directory/zipfile is automatically inserted as the
4456 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004458- Issue #1265: Fix a problem with sys.settrace, if the tracing
4459 function uses a generator expression when at the same time the
4460 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004461
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004462- sets and frozensets now have an isdisjoint() method.

4465
Neal Norwitz44f326e2007-10-05 05:29:17 +00004466- Fix warnings found by the new version of the Coverity checker.
4467
Georg Brandl21e99f42010-03-07 15:23:59 +00004468- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004469 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4470 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004471
Georg Brandl3ee81df2008-05-17 18:14:43 +00004472- Issue #1686386: Tuple's tp_repr did not take into account the
4473 possibility of having a self-referential tuple, which is possible
4474 from C code. Nor did object's tp_str consider that a type's tp_str
4475 could do something that could lead to an inifinite recursion.
4476 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4477 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004478
Georg Brandl3ee81df2008-05-17 18:14:43 +00004479- Issue #1164: It was possible to trigger deadlock when using the
4480 'print' statement to write to a file since the GIL was not released
4481 as needed. Now PyObject_Print() does the right thing along with
4482 various tp_print implementations of the built-in types and those in
4483 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004484
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Issue #1147: Exceptions were directly allowing string exceptions in
4486 their throw() method even though string exceptions no longer
4487 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004488
Georg Brandl3ee81df2008-05-17 18:14:43 +00004489- Issue #1096: Prevent a segfault from getting the repr of a very
4490 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004491
Brett Cannon1e534b52007-09-07 04:18:30 +00004492- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004493 PyObject_Call() never calling back out to Python code to trigger
4494 recursion depth updates/checks. Required the creation of a static
4495 RuntimeError instance in case normalizing an exception put the
4496 recursion check value past its limit. Fixes crashers
4497 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004498

Neal Norwitz0ac60192007-05-27 04:08:54 +00004512- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004513 __*__ attributes. (Some already existed, e.g., __doc__ and
4514 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004515
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004516- Add -3 option to the interpreter to warn about features that are
4517 deprecated and will be changed/removed in Python 3.0.
4518
Georg Brandl2134e752007-05-21 20:34:16 +00004519- Patch #1686487: you can now pass any mapping after '**' in function
4520 calls.
4521
Collin Winter62903052007-05-18 23:11:24 +00004522- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004523 "except E as target:". This is to provide forwards compatibility
4524 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004525
Brett Cannon229cee22007-05-05 01:34:02 +00004526- Deprecate BaseException.message as per PEP 352.
4527
Georg Brandl3ee81df2008-05-17 18:14:43 +00004528- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004529 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004530
Vinay Sajip8549ce32007-05-06 17:53:37 +00004531- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004532 setting a plain string, ie don't expand to single letter identifiers.
4533
Raymond Hettinger13936692007-04-11 18:40:58 +00004534- Request #1191699: Slices can now be pickled.
4535
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004536- Request #1193128: str.translate() now allows a None argument for
4537 translations that only remove characters without re-mapping the
4538 remaining characters.
4539
Georg Brandl5cb76c12007-03-21 09:00:39 +00004540- Patch #1682205: a TypeError while unpacking an iterable is no longer
4541 masked by a generic one with the message "unpack non-sequence".
4542
Neal Norwitzaa754b72007-03-21 06:39:48 +00004543- Remove unused file Python/fmod.c.
4544
Guido van Rossum143b5642007-03-23 04:58:42 +00004545- Bug #1683368: The object.__init__() and object.__new__() methods are
4546 now stricter in rejecting excess arguments. The only time when
4547 either allows excess arguments is when it is not overridden and the
4548 other one is. For backwards compatibility, when both are
4549 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004550 warning later). Also, type.__init__() insists on the same signature
4551 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004552
Georg Brandl3ee81df2008-05-17 18:14:43 +00004553- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4554 object to complex using its __complex__() method before falling back
4555 to the __float__() method. Therefore, the functions in the cmath
4556 module now can operate on objects that define a __complex__()
4557 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004558
Georg Brandl3ee81df2008-05-17 18:14:43 +00004559- Patch #1623563: allow __class__ assignment for classes with
4560 __slots__. The old and the new class are still required to have the
4561 same slot names.

4567 ``object.__reduce_ex__()`` is called with an object that is faking
4568 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004569
Georg Brandl3ee81df2008-05-17 18:14:43 +00004570- Patch #1680015: Don't modify __slots__ tuple if it contains an

4574
Georg Brandl7b9c5552007-03-12 14:30:05 +00004575- Bug #1678647: write a newline after printing an exception in any
4576 case, even when converting the value to a string failed.
4577
Georg Brandl871f1bc2007-03-12 13:17:36 +00004578- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004579 its argument, if it exists. If not, it will work like before. This
4580 allows customizing the output of dir() in the presence of a
4581 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004589- Patch #1491866: change the complex() constructor to allow
4590 parthensized forms. This means complex(repr(x)) now works instead of
4591 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004592
Georg Brandlaa2321b2007-03-07 00:40:28 +00004593- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004594 makes the filenames the warning module prints much more sensible
4595 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004596

Georg Brandl0fca97a2007-03-05 22:28:08 +00004608- Patch #1674228: when assigning a slice (old-style), check for the
4609 sq_ass_slice instead of the sq_slice slot.
4610
Georg Brandl3ee81df2008-05-17 18:14:43 +00004611- When printing an unraisable error, don't print exceptions. before
4612 the name. This duplicates the behavior whening normally printing
4613 exceptions.

5242 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005523- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5524 with RFC 3207 and forgets any knowledge obtained from the server not
5525 obtained from the TLS negotiation itself. Patch contributed by Bill
5526 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005527
Georg Brandl3ee81df2008-05-17 18:14:43 +00005528- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005529 that the SMTP.starttls() caller no longer needs to call ehlo()
5530 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005531 does not claim to support starttls. Adds the
5532 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5613 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5614 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00005616

Georg Brandl3ee81df2008-05-17 18:14:43 +00005631 time so that opening a database previously created with the DB_DUP
5632 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5633 opens. Specifically: dictionary assignment to a DB object will
5634 replace all values for a given key when the database allows
5635 duplicate values. DB users should use DB.put(k, v) when they want
5636 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005637

5643 characters with ASCII value less than 32. Also, it correctly quotes
5644 dots only if they occur on a single line, as opposed to the previous
5645 behavior of quoting dots if they are the second character of any
5646 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005647

5970
Georg Brandl3ee81df2008-05-17 18:14:43 +00005971- Unified naming convention for free lists and their limits. All free
5972 lists in Object/ are named ``free_list``, the counter ``numfree``

Christian Heimes5b970ad2008-02-06 13:33:44 +00005975
Georg Brandl3ee81df2008-05-17 18:14:43 +00005976- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5977 to ``PyTuple_SetItem``, it can be used to populate a brand new

5990
Georg Brandl3ee81df2008-05-17 18:14:43 +00005991- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5992 of w# format code incorrectly truncated the length to an int, even
5993 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5994 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005995
Georg Brandl3ee81df2008-05-17 18:14:43 +00005996- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6014- Fix some leftovers from the conversion from int to Py_ssize_t
6015 (relevant to strings and sequences of more than 2**31 items).
6016
6017- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6018 outside of pystate.c and should not be necessary.
6019
Georg Brandl3ee81df2008-05-17 18:14:43 +00006020- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6021 absolute imports. In earlier versions they might have used relative
6022 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006023
Georg Brandl3ee81df2008-05-17 18:14:43 +00006024- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6025 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006026
Georg Brandl3ee81df2008-05-17 18:14:43 +00006027- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

6037 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006038

Georg Brandl3ee81df2008-05-17 18:14:43 +00006052- Removed the macfs module. It had been deprecated since Python 2.5.
6053 This lead to the deprecation of macostools.touched() as it relied
6054 solely on macfs and was a no-op under OS X.
