Mark Dickinsondbbed042011-09-19 16:38:08 +0100344- Issue #12973: Fix overflow checks that invoked undefined behaviour in
345 int.__pow__. These overflow checks were causing int.__pow__ to produce
346 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100347 compiler optimizing the check away. Also fix similar overflow checks
348 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
349 bugs caused test failures with recent versions of Clang.

362 and its type get caught in a reference cycle, and the instance's

Florent Xiclunac2279652012-02-12 14:49:03 +0100417- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100418 has left two versions of customize_compiler, the original in
419 distutils.sysconfig and another copy in distutils.ccompiler, with some

423
Ned Deily0d0ea482012-02-10 12:59:06 +0100424- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
425 Distutils-based packages with C extension modules may fail because
426 Apple has removed gcc-4.2, the version used to build python.org
427 64-bit/32-bit Pythons. If the user does not explicitly override
428 the default C compiler by setting the CC environment variable,
429 Distutils will now attempt to compile extension modules with clang
430 if gcc-4.2 is required but not found. Also as a convenience, if
431 the user does explicitly set CC, substitute its value as the default
432 compiler in the Distutils LDSHARED configuration variable for OS X.
433 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
434 SDK, neither of which are available in Xcode 4. This change does not
435 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700708- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
709 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
710 interpreter process. This could cause failures in non-Distutils subprocesses
711 and was unreliable since tests or user programs could modify the interpreter
712 environment after Distutils set it. Instead, have Distutils set the the
713 deployment target only in the environment of each build subprocess. It is
714 still possible to globally override the default by setting
715 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
716 greater or equal to the default value, the value with which the interpreter
717 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400745- sys.setcheckinterval() now updates the current ticker count as well as
746 updating the check interval, so if the user decreases the check interval,
747 the ticker doesn't have to wind down to zero from the old starting point
748 before the new interval takes effect. And if the user increases the
749 interval, it makes sure the new limit takes effect right away rather have an
750 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001698- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1699 This prevents user-created self-referencing ordered dictionaries from
1700 becoming permanently uncollectable GC garbage. The downside is that
1701 removing __del__ means that the internal doubly-linked list has to wait for
1702 GC collection rather than freeing memory immediately when the refcnt drops
1703 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002162- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2163 start byte and the continuation byte(s) are now considered invalid, instead
2164 of the number of bytes specified by the start byte.
2165 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2166 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2167 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002176- Issue #8748: Fix two issues with comparisons between complex and integer
2177 objects. (1) The comparison could incorrectly return True in some cases
2178 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2179 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00002563- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2564 with a non-empty format string. This is an effort to future-proof user
2565 code. If a derived class does not currently implement __format__ but later
2566 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002567 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002568 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002618- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2619 InvalidOperation instead of returning False. (Comparisons involving a quiet
2620 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2621 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00002623- Issue #2531: Comparison operations between floats and Decimal instances now
2624 return a result based on the numeric values of the operands; previously they
2625 returned an arbitrary result based on the relative ordering of id(float) and
2626 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00002640- Comparisons using one of <, <=, >, >= between a complex instance and a
2641 Fractions instance now raise TypeError instead of returning True/False. This
2642 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2643 <=> complex, and complex <=> complex comparisons.

Antoine Pitroud840e512010-02-04 20:20:18 +00003053- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003054 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003055 Also, raise ValueError rather than TypeError when an unknown TIPC address
3056 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003060- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003061 file position when calling `truncate()`. It would previously change the file
3062 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003063 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3064
Georg Brandlba83f822010-03-14 09:50:54 +00003065- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3066 class used to represent files stored inside an archive. The new
3067 implementation is significantly faster and can be wrapped in a
3068 ``io.BufferedReader`` object for more speedups. It also solves an issue
3069 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003080- Issue #7748: Since unicode values are supported for some metadata options in
3081 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3082 encoded string for them. This ensures that the upload and register commands
3083 send the correct values to PyPI without any error.

3157Core and Builtins
3158-----------------
3159
Georg Brandlba83f822010-03-14 09:50:54 +00003160- The ``__complex__()`` method is now looked up on the class of instances to
3161 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003163- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3164 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3165
Mark Dickinson1b34d252010-01-01 17:27:30 +00003166- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003167 DeprecationWarning when passed a float argument where an integer was expected.
3168 These functions and methods now raise TypeError instead. The majority of the
3169 effects of this change are in the extension modules, but some core functions
3170 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3171 and many unicode/str methods.

3185 of integers: the result of a/b is now correctly rounded for ints a and b (at
3186 least on IEEE 754 platforms), and in particular does not depend on the
3187 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00003194 executables on OSX.
3195
Georg Brandlba83f822010-03-14 09:50:54 +00003196 These executables now work properly with the arch(1) command: ``arch -ppc
3197 python`` will start a universal binary version of python in PPC mode (unlike
3198 previous releases).

3338 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003339

Georg Brandlba83f822010-03-14 09:50:54 +00003354- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3355 decimal string that's guaranteed to round back to x under correct rounding
3356 (with round-half-to-even rounding mode). Previously it gave a string based on
3357 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3358 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3359 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003360
Georg Brandlba83f822010-03-14 09:50:54 +00003361- Issue #7117: On almost all platforms: float-to-string and string-to-float
3362 conversions within Python are now correctly rounded. Places these conversions
3363 occur include: str for floats and complex numbers; the float and complex
3364 constructors; old-style and new-style numeric formatting; serialization and
3365 deserialization of floats and complex numbers using marshal, pickle and json;
3366 parsing of float and imaginary literals in Python code; Decimal-to-float
3367 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003368
Georg Brandlba83f822010-03-14 09:50:54 +00003369 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3370 providing correctly-rounded strtod and dtoa C functions. This code is
3371 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3372 the C compiler. There may be a small number of platforms on which correct
3373 operation of this code cannot be guaranteed, so the code is not used: notably,
3374 this applies to platforms where the C double format is not IEEE 754 binary64,
3375 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3376 and Python's configure script is unable to determine how to change the FPU
3377 precision. On these platforms conversions use the platform strtod and dtoa,
3378 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003380- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3381 uses the correctly-rounded string <-> float conversions described above (when
3382 available), and so produces correctly rounded results that will display nicely
3383 under the float repr. There are two related small changes: (1) round now
3384 accepts any class with an ``__index__()`` method for its second argument (but
3385 no longer accepts floats for the second argument), and (2) an excessively
3386 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3387 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003530 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3531 (2) parsing of strings representing infinities and nans was locale aware; and
3532 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003534- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3535 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3536 but with at least one decimal point and with a default precision
3537 of 12. Previously, the behavior the same but with a default precision of 6.
3538 This more closely matches ``str()``, and reduces surprises when adding
3539 alignment flags to the empty presentation type. This also affects the new
3540 complex.__format__ in the same way.
3541
3542- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00003738- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3739 file objects with closefd=False. The file descriptor is still kept open but
3740 the file object behaves like a closed file. The ``FileIO`` object also got a
3741 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00003764- On windows, ``os.chdir()`` given unicode was not working if

3766 this code path is really executed because I cannot move to such directory on

3771 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00003792- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3793 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3794 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3795 of using the replace error handler in PyUnicode_DecodeUTF8().
3796
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003797- Issue #3739: The unicode-internal encoder now reports the number of characters

3799
Georg Brandlba83f822010-03-14 09:50:54 +00003800- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3802 gives improved memory leak detection when running under Valgrind, while taking
3803 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005168- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5169
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005170- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5171 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5172 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5173 ``printf`` function, whereas PyString_FromFormat has an independent
5174 implementation and uses "%zd" on all platforms for size_t values.
5175 This makes a difference on win64, where ``printf`` needs "%Id" to display
5176 64bit values.
5177
Benjamin Peterson97179b02008-09-09 20:55:01 +00005178- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5182 object; previously an int would be returned for small values. the __long__
5183 method is allowed to return either an int or a long, but the behaviour of
5184 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005186- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00005192 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005193 was correctly parsed but parsing of subsequent arguments failed.
5194
Vinay Sajip35e3b032008-09-01 14:33:59 +00005195- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005196 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5197 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5198 when given a tuple of classes as second argument, were looking up
5199 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5200 type object.
5201

5345-----------------
5346
Guido van Rossumf8402962008-08-20 15:01:50 +00005347- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5348 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5349 extensions do not automatically benefit from the class attribute
5350 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5351 to their tp_flags field if they care. This is a backwards
5352 compatibility feature; in 3.0, all types will use the cache by
5353 default.
5354
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005355- Keyword arguments can now follow starred arguments. (``f(a, *args,
5356 keyword=23)`` is now valid syntax.)
5357
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005358- ctypes function pointers that are COM methods have a boolean True
5359 value again.
5360
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005361- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5362 by denying s# to parse objects that have a releasebuffer procedure,
5363 and introducing s*.
5364
Georg Brandl1e13ea92008-08-11 09:07:59 +00005365- Issue #3537: Fix an assertion failure when an empty but presized dict
5366 object was stored in the freelist.
5367
Mark Dickinsonb6467572008-08-04 21:30:09 +00005368- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5369 ValueError consistently across platforms.
5370
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005371- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5372 (64bit Unix, for example), unichr() would truncate its argument and return
5373 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5374
Neal Norwitze7d8be82008-07-31 17:17:14 +00005375- Apply security patches from Apple.
5376
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005377- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

5379
Antoine Pitrou92f82162008-07-25 22:22:08 +00005380- Issue #1819: function calls with several named parameters are now on
5381 average 35% faster (as measured by pybench).
5382
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005383- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5384 the python debugger steps into a class statement: the free variables (local
5385 variables defined in an outer scope) would be deleted from the outer scope.
5386
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005387- Issue #2620: Overflow checking when allocating or reallocating memory
5388 was not always being done properly in some python types and extension
5389 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5390 all been updated to perform better checks and places in the code that
5391 would previously leak memory on the error path when such an allocation

5398
Benjamin Petersone977ad42008-08-20 01:42:01 +00005399- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5400 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5401
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005402- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5403 version reported by these tools does not necessarily follow the python
5404 version numbering scheme, so the module is less strict when parsing it.
5405
Nick Coghlanf70385a2008-08-18 12:42:46 +00005406- Issue #2235: Added Py3k warnings for types which will become unhashable
5407 under the stricter __hash__ inheritance rules in 3.0. Several types
5408 which did not meet the rules for hash invariants and were already
5409 unhashable in 3.0 have now been explicitly flagged as unhashable in
5410 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5411 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5412
Brett Cannon88f801d2008-08-18 00:46:22 +00005413- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5414 imported into the module but exposed as part of the module's API.
5415
Brett Cannon7b96f072008-08-18 00:41:11 +00005416- Remove an unneeded import of abc.ABCMeta from 'inspect'.

5421
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005422- Issue #3575: Incremental decoder's decode function now takes bytearray
5423 by using 's*' instead of 't#'.
5424
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005425- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005426 fails unicode conversion on 2nd parameter. (windows only)
5427
Georg Brandl222e2082010-08-01 22:27:39 +00005428- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005429 in a redirect.
5430
Brett Cannonabe423e2008-08-16 21:47:07 +00005431- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005432 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005433
Facundo Batistaeb90b782008-08-16 14:44:07 +00005434- Issue #2776: fixed small issue when handling an URL with double slash
5435 after a 302 response in the case of not going through a proxy.
5436
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005437- Issue #2676: in the email package, content-type parsing was hanging on
5438 pathological input because of quadratic or exponential behaviour of a
5439 regular expression.
5440
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005441- Issue #3476: binary buffered reading through the new "io" library is now
5442 thread-safe.
5443
Brett Cannonbf3157b2008-08-14 05:00:03 +00005444- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5445 since mimetools itself is deprecated. Because modules are cached, all
5446 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5447
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005448- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00005450- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5451 menu entries were not deleted.
5452
Brett Cannon83e81842008-08-09 23:30:55 +00005453- Copied the implementation of reduce() to _functools.reduce() to have a
5454 version that did not raise a DeprecationWarning under -3.
5455
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005456- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5457 a MemoryError rather than silently stop the iteration.
5458
Guido van Rossum59ce9012008-08-09 14:55:34 +00005459- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5460 to _sre.compile() will now be rejected. This should not affect anybody
5461 since the re.compile() function never generates invalid re-bytecode.
5462
Skip Montanaroa032bf42008-08-08 22:52:51 +00005463- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5464 upon first access it can be automatically initialized from the csv file if
5465 it wasn't initialized during instantiation.
5466
Brett Cannon3aa2a492008-08-06 22:28:09 +00005467- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5468 the reload() built-in has been removed.
5469
Brett Cannon7e30b672008-08-04 21:52:25 +00005470- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005471 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5479 raised an AttributeError.
5480
Benjamin Peterson01a24322008-07-28 23:35:27 +00005481- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005482 asking for a specific length. This problem only affected files opened
5483 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005484

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005508- Issue #3394: zipfile.writestr sets external attributes when passed a
5509 file name rather than a ZipInfo instance, so files are extracted with
5510 mode 0600 rather than 000 under Unix.
5511
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005512- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5513 argument in python 2.5, this broke code that subclassed Popen to include its
5514 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5525 interaction with the tp_hash slot (added in 2.6b2) are now documented
5526
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005527- Issue #643841: The language reference now provides more detailed
5528 coverage of the lookup process for special methods. The disclaimers
5529 regarding lack of coverage of new-style classes have also been
5530 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005538Core and Builtins
5539-----------------
5540
Georg Brandl3e483f62008-07-16 22:57:41 +00005541- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5542 its methods now allow for items objects that can be converted to
5543 an integer using operator.index().
5544
Mark Dickinson64b7e502008-07-16 09:40:03 +00005545- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5546 produced a ValueError instead of giving the correct float.
5547
Eric Smitha5fa5a22008-07-16 00:11:49 +00005548- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5549 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5550
Mark Dickinson7103aa42008-07-15 19:08:33 +00005551- Issue #3008: the float type has a new instance method 'float.hex'
5552 and a new class method 'float.fromhex' to convert floating-point
5553 numbers to and from hexadecimal strings, respectively.
5554
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005555- Issue #2235: __hash__ is once again inherited by default. To allow
5556 collections.Hashable to remain meaningful in the presence of the
5557 default hash implementation (object.__hash__), it is now possible
5558 to explicit block inheritance of hash by setting __hash__=None at
5559 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5560 level.
5561
Nick Coghlanb028f502008-07-13 14:52:36 +00005562- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5563 the parent module cannot be found while performing an absolute import.
5564 This means that an incorrectly defined __package__ attribute will
5565 now only prevent relative imports in that module rather than causing
5566 all imports from that module to fail.
5567
Nick Coghlan14ff9942008-07-08 14:21:42 +00005568- Issue #2517: Allow unicode messages in Exceptions again by correctly
5569 bypassing the instance dictionary when looking up __unicode__ on
5570 new-style classes.
5571
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005572- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5573 set to a custom object whose write() method happens to install
5574 another file in sys.stdout.
5575
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005576- Issue #3088: Corrected a race condition in classes derived from
5577 threading.local: the first member set by a thread could be saved in
5578 another thread's dictionary.
5579
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005580- Issue #3004: Minor change to slice.indices(): the start and stop
5581 arguments are now treated identically, making the behaviour easier
5582 to describe and understand. For example, slice(None, -10,
5583 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5584 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5585 10, -1).
5586
Georg Brandl278fc502008-07-19 12:46:12 +00005587- Issue #3219: Calling a function with repeated keyword arguments,
5588 f(a=2, a=23), would not cause a syntax error. This was a regression
5589 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005590
Georg Brandl278fc502008-07-19 12:46:12 +00005591- Issue #2862: Make int and float freelist management consistent with
5592 other freelists. Changes their CompactFreeList apis into
5593 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005594

5596-------
5597
Thomas Heller57adf222008-08-14 19:10:48 +00005598- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5599 api functions without holding the GIL, which could lead to a fatal
5600 error when they failed.
5601
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005602- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005610- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5611 ForkingPickler.register() to resolve conflict with ctypes.
5612
Vinay Sajip51e65192008-07-18 09:01:10 +00005613- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005614
Thomas Heller880f5292008-07-15 19:39:38 +00005615- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5616 a valid dlerror() message.
5617
Thomas Heller2bad6572008-07-15 17:19:50 +00005618- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5619 incomplete structure was created.

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005625- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005626
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005627- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5628 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005629 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005630 content-length. The problem had been corrected in the 2.4 branch, but never
5631 merged into trunk.
5632

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005646- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5647 handling is now the same as that of other special attributes like __name__).
5648
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005649- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00006039 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006040
6041 This is controlled by the configure argument ``--with-universal-archs``:
6042
6043 - ``--with-universal-archs=all``: install 4-way universal
6044
6045 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6046
6047 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6048
6049 This option should be used in combination with ``--enable-universalsdk=``.
6050
6051 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006101- Issue #1631171: Re-implement the 'warnings' module in C (the
6102 original Python code has been kept as backup). This will allow for
6103 using the 'warning's machinery in such places as the parser where
6104 use of pure Python code is not possible. Both the ``showarning()``
6105 and ``formatwarning()`` gain an optional 'line' argument which is
6106 not called by default for backwards-compatibility reasons. Setting
6107 ``warnings.showwarning()`` to an implementation that lacks support
6108 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006171- Issue #2550: The approach used by client/server code for obtaining
6172 ports to listen on in network-oriented tests has been refined in an
6173 effort to facilitate running multiple instances of the entire
6174 regression test suite in parallel without issue.
6175 test_support.bind_port() has been fixed such that it will always
6176 return a unique port -- which wasn't always the case with the
6177 previous implementation, especially if socket options had been set
6178 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6179 new implementation of bind_port() will actually raise an exception
6180 if it is passed an AF_INET/SOCK_STREAM socket with either the
6181 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6182 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6183 the socket it's been passed. This currently only applies to
6184 Windows. This option prevents any other sockets from binding to the
6185 host/port we've bound to, thus removing the possibility of the
6186 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6187 when a second SOCK_STREAM socket binds and accepts to a host/port
6188 that's already been bound by another socket. The optional preferred
6189 port parameter to bind_port() has been removed. Under no
6190 circumstances should tests be hard coding ports!
6191
6192 test_support.find_unused_port() has also been introduced, which will
6193 pass a temporary socket object to bind_port() in order to obtain an
6194 unused port. The temporary socket object is then closed and
6195 deleted, and the port is returned. This method should only be used
6196 for obtaining an unused port in order to pass to an external program
6197 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6198 a parameter to a server-oriented class that doesn't give you direct
6199 access to the underlying socket used.
6200
6201 Finally, test_support.HOST has been introduced, which should be used
6202 for the host argument of any relevant socket calls (i.e. bind and
6203 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006204
6205 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006206 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006207 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6208 test_asynchat and test_socket_ssl.
6209
Georg Brandl3ee81df2008-05-17 18:14:43 +00006210 It is now possible for multiple instances of the regression test
6211 suite to run in parallel without issue.

6485- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006486
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006487- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006488 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006489
Eric Smitha73fbe72008-02-23 03:09:44 +00006490- Added the future_builtins module, which contains hex() and oct().
6491 These are the PEP 3127 version of these functions, designed to be
6492 compatible with the hex() and oct() builtins from Python 3.0. They
6493 differ slightly in their output formats from the existing, unchanged
6494 Python 2.6 builtins. The expected usage of the future_builtins
6495 module is:
6496 from future_builtins import hex, oct
6497
Eric Smith7ef40bf2008-02-20 23:34:22 +00006498- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6499 exponents for exponents with absolute value < 100. Follows C99
6500 standard. This is a change on Windows, which would use 3 digits.
6501 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6502 so that any alterations it does to the resulting string will be
6503 available in stringlib/formatter.h (for float.__format__).
6504
Eric Smith5a3c1352008-02-19 13:21:56 +00006505- Implemented PEP 3101, Advanced String Formatting. This adds a new
6506 builtin format(); a format() method for str and unicode; a
6507 __format__() method to object, str, unicode, int, long, float, and
6508 datetime; the class string.Formatter; and the C API
6509 PyObject_Format().
6510
Georg Brandl3ee81df2008-05-17 18:14:43 +00006511- Fixed several potential crashes, all caused by specially crafted
6512 __del__ methods exploiting objects in temporarily inconsistent
6513 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006514
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006515- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006516 prevent a possible crash: an Abstract Base Class would try to access
6517 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006518
Georg Brandl3ee81df2008-05-17 18:14:43 +00006519- Fixed repr() and str() of complex numbers with infinity or nan as
6520 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006522- Clear all free lists during a gc.collect() of the highest generation
6523 in order to allow pymalloc to free more arenas. Python may give back
6524 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006525
Georg Brandl3ee81df2008-05-17 18:14:43 +00006526- Issue #2045: Fix an infinite recursion triggered when printing a
6527 subclass of collections.defaultdict, if its default_factory is set
6528 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006529
Christian Heimesf75dbef2008-02-08 00:11:31 +00006530- Fixed a minor memory leak in dictobject.c. The content of the free
6531 list was not freed on interpreter shutdown.
6532
Georg Brandl21e99f42010-03-07 15:23:59 +00006533- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006534 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006535
Georg Brandl3ee81df2008-05-17 18:14:43 +00006536- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6537 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006538 to compact the internal free lists of pre-allocted ints and floats.
6539
Georg Brandl3ee81df2008-05-17 18:14:43 +00006540- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6541 calls. Python expected the return type int but the fork familie
6542 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006543
Georg Brandl3ee81df2008-05-17 18:14:43 +00006544- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6545 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006546
Georg Brandl3ee81df2008-05-17 18:14:43 +00006547- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6548 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006553- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6554 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006555
Georg Brandl3ee81df2008-05-17 18:14:43 +00006556- Patch #1473257: generator objects gain a gi_code attribute. This is
6557 the same object as the func_code attribute of the function that
6558 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006559
Georg Brandl3ee81df2008-05-17 18:14:43 +00006560- Issue #1920: "while 0" statements were completely removed by the
6561 compiler, even in the presence of an "else" clause, which is
6562 supposed to be run when the condition is false. Now the compiler
6563 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006564
Guido van Rossumeead05f2008-01-24 18:21:02 +00006565- A few crashers fixed: weakref_in_del.py (issue #1377858);
6566 loosing_dict_ref.py (issue #1303614, test67.py);
6567 borrowed_ref_[34].py (not in tracker).
6568
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006569- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006570 suppressed while an extension is loaded by calling SetErrorMode in
6571 dynload_win.c. The error is still reported properly.
6572
Georg Brandl3ee81df2008-05-17 18:14:43 +00006573- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006574 several extension methods and modules do not work without unicode
6575 support.
6576
Georg Brandl26543b12008-01-21 18:36:51 +00006577- Issue #1882: when compiling code from a string, encoding cookies in the
6578 second line of code were not always recognized correctly.
6579
Georg Brandl14404b62008-01-19 19:27:05 +00006580- Issue #1679: "0x" was taken as a valid integer literal.
6581
Georg Brandl6caad7d2008-01-26 14:19:22 +00006582- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006583 added.
6584
Christian Heimesc94e2b52008-01-14 04:13:37 +00006585- sys.float_info / PyFloat_GetInfo: The floating point information
6586 object was converted from a dict to a specialized structseq object.
6587
Georg Brandl3ee81df2008-05-17 18:14:43 +00006588- Patch #1816: Added sys.flags structseq. It exposes the status of
6589 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006590
Georg Brandl3ee81df2008-05-17 18:14:43 +00006591- Objects/structseq.c: Implemented new structseq representation. The
6592 patch makes structseqs (e.g. the return value of os.stat) more
6593 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006594
Georg Brandl3ee81df2008-05-17 18:14:43 +00006595- Patch #1700288: added a type attribute cache that caches method
6596 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006597
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006598- Bug #1776: __import__() no longer accepts filenames on any platform.

6602
Georg Brandl3ee81df2008-05-17 18:14:43 +00006603- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6604 envvar and sys.dont_write_bytecode attribute. All these can be set
6605 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006606
Georg Brandl3ee81df2008-05-17 18:14:43 +00006607- Improve some exception messages when Windows fails to load an
6608 extension module. Now we get for example '%1 is not a valid Win32
6609 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006616- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006617 and INF. float("nan"), float("inf") and float("-inf") now work on
6618 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006619
Georg Brandl3ee81df2008-05-17 18:14:43 +00006620- Compiler now generates simpler and faster code for dictionary
6621 literals. The oparg for BUILD_MAP now indicates an estimated
6622 dictionary size. There is a new opcode, STORE_MAP, for adding
6623 entries to the dictionary.

6666
Georg Brandl21e99f42010-03-07 15:23:59 +00006667- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006668 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6669 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006670
Georg Brandl3ee81df2008-05-17 18:14:43 +00006671- Issue #1686386: Tuple's tp_repr did not take into account the
6672 possibility of having a self-referential tuple, which is possible
6673 from C code. Nor did object's tp_str consider that a type's tp_str
6674 could do something that could lead to an inifinite recursion.
6675 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6676 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006677
Georg Brandl3ee81df2008-05-17 18:14:43 +00006678- Issue #1164: It was possible to trigger deadlock when using the
6679 'print' statement to write to a file since the GIL was not released
6680 as needed. Now PyObject_Print() does the right thing along with
6681 various tp_print implementations of the built-in types and those in
6682 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006683
Georg Brandl3ee81df2008-05-17 18:14:43 +00006684- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00006691- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006692 PyObject_Call() never calling back out to Python code to trigger
6693 recursion depth updates/checks. Required the creation of a static
6694 RuntimeError instance in case normalizing an exception put the
6695 recursion check value past its limit. Fixes crashers

6719 calls.
6720
Collin Winter62903052007-05-18 23:11:24 +00006721- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006722 "except E as target:". This is to provide forwards compatibility
6723 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006727- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006728 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006730- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006731 setting a plain string, ie don't expand to single letter identifiers.
6732
Raymond Hettinger13936692007-04-11 18:40:58 +00006733- Request #1191699: Slices can now be pickled.
6734

6743
Guido van Rossum143b5642007-03-23 04:58:42 +00006744- Bug #1683368: The object.__init__() and object.__new__() methods are
6745 now stricter in rejecting excess arguments. The only time when
6746 either allows excess arguments is when it is not overridden and the
6747 other one is. For backwards compatibility, when both are
6748 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006749 warning later). Also, type.__init__() insists on the same signature
6750 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006751
Georg Brandl3ee81df2008-05-17 18:14:43 +00006752- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6753 object to complex using its __complex__() method before falling back
6754 to the __float__() method. Therefore, the functions in the cmath
6755 module now can operate on objects that define a __complex__()
6756 method.

6773
Georg Brandl7b9c5552007-03-12 14:30:05 +00006774- Bug #1678647: write a newline after printing an exception in any
6775 case, even when converting the value to a string failed.
6776
Georg Brandl871f1bc2007-03-12 13:17:36 +00006777- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006778 its argument, if it exists. If not, it will work like before. This
6779 allows customizing the output of dir() in the presence of a
6780 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00006782- Patch #922167: Python no longer segfaults when faced with infinitely
6783 self-recursive reload() calls (as reported by bug #742342).

6789 parthensized forms. This means complex(repr(x)) now works instead of
6790 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006791
Georg Brandlaa2321b2007-03-07 00:40:28 +00006792- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006793 makes the filenames the warning module prints much more sensible
6794 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006795

Georg Brandl0fca97a2007-03-05 22:28:08 +00006807- Patch #1674228: when assigning a slice (old-style), check for the
6808 sq_ass_slice instead of the sq_slice slot.
6809
Georg Brandl3ee81df2008-05-17 18:14:43 +00006810- When printing an unraisable error, don't print exceptions. before
6811 the name. This duplicates the behavior whening normally printing
6812 exceptions.

6863 embedded in the string to convert.
6864
Georg Brandl846f73a2006-10-08 07:11:54 +00006865- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006913 generator expressions (x for x, in ... ) works again. Fixing this
6914 problem required changing the .pyc magic number. This means that
6915 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007345 AttributeError instead of an IOError when the server's response

7437 TestCase and TestSuite subclasses (not instances) are no longer
7438 accepted in TestSuite.addTest(). This should cause no

7440 -- the failure just occurred later, with a more cumbersome
7441 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007722- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7723 with RFC 3207 and forgets any knowledge obtained from the server not
7724 obtained from the TLS negotiation itself. Patch contributed by Bill
7725 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007726
Georg Brandl3ee81df2008-05-17 18:14:43 +00007727- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007728 that the SMTP.starttls() caller no longer needs to call ehlo()
7729 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007730 does not claim to support starttls. Adds the
7731 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7732 Fenner.

7812 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7813 silently miscode subclasses of those types. Now, it raises a
7814 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007815

Georg Brandl3ee81df2008-05-17 18:14:43 +00007830 time so that opening a database previously created with the DB_DUP
7831 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7832 opens. Specifically: dictionary assignment to a DB object will
7833 replace all values for a given key when the database allows
7834 duplicate values. DB users should use DB.put(k, v) when they want
7835 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007836

7842 characters with ASCII value less than 32. Also, it correctly quotes
7843 dots only if they occur on a single line, as opposed to the previous
7844 behavior of quoting dots if they are the second character of any
7845 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007846

Georg Brandl3ee81df2008-05-17 18:14:43 +00008251- Removed the macfs module. It had been deprecated since Python 2.5.
8252 This lead to the deprecation of macostools.touched() as it relied
8253 solely on macfs and was a no-op under OS X.
