Ned Deily18fae3f2013-01-31 01:24:55 -08001264- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1265 In particular, fix extension module build failures when trying to use
1266 32-bit-only installer Pythons on systems with Xcode 4 (currently
1267 OS X 10.8, 10.7, and optionally 10.6).
1268 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1269 * Since Xcode 4 removes ppc support, extension module builds now
1270 check for ppc compiler support and by default remove ppc and
1271 ppc64 archs when they are not available.
1272 * Extension module builds now revert to using system installed
1273 headers and libs (/usr and /System/Library) if the SDK used
1274 to build the interpreter is not installed or has moved.
1275 * Try to avoid building extension modules with deprecated
1276 and problematic Apple llvm-gcc compiler. If original compiler
1277 is not available, use clang instead by default.

1709 Distutils-based packages with C extension modules may fail because
1710 Apple has removed gcc-4.2, the version used to build python.org
1711 64-bit/32-bit Pythons. If the user does not explicitly override
1712 the default C compiler by setting the CC environment variable,
1713 Distutils will now attempt to compile extension modules with clang
1714 if gcc-4.2 is required but not found. Also as a convenience, if
1715 the user does explicitly set CC, substitute its value as the default
1716 compiler in the Distutils LDSHARED configuration variable for OS X.
1717 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1718 SDK, neither of which are available in Xcode 4. This change does not
1719 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001969- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1970 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1971 interpreter process. This could cause failures in non-Distutils subprocesses
1972 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001973 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001974 deployment target only in the environment of each build subprocess. It is
1975 still possible to globally override the default by setting
1976 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1977 greater or equal to the default value, the value with which the interpreter
1978 was built.

2008 the ticker doesn't have to wind down to zero from the old starting point
2009 before the new interval takes effect. And if the user increases the
2010 interval, it makes sure the new limit takes effect right away rather have an
2011 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002991- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2992 This prevents user-created self-referencing ordered dictionaries from
2993 becoming permanently uncollectable GC garbage. The downside is that
2994 removing __del__ means that the internal doubly-linked list has to wait for
2995 GC collection rather than freeing memory immediately when the refcnt drops
2996 to zero.

3457 of the number of bytes specified by the start byte.
3458 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003841- Issue #7301: Add environment variable $PYTHONWARNINGS.
3842
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003843- Issue #8329: Don't return the same lists from select.select when no fds are
3844 changed.
3845
Georg Brandlfee0f442010-05-22 21:26:21 +00003846- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

3855
Georg Brandlfee0f442010-05-22 21:26:21 +00003856- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3857 with a non-empty format string. This is an effort to future-proof user
3858 code. If a derived class does not currently implement __format__ but later
3859 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003860 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003861 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003894- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00003911- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3912 InvalidOperation instead of returning False. (Comparisons involving a quiet
3913 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3914 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003915
Georg Brandlfee0f442010-05-22 21:26:21 +00003916- Issue #2531: Comparison operations between floats and Decimal instances now
3917 return a result based on the numeric values of the operands; previously they
3918 returned an arbitrary result based on the relative ordering of id(float) and
3919 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003920
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003921- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003922 argument `-` which tells it to read files to compile from stdin. Each line is
3923 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00003933- Comparisons using one of <, <=, >, >= between a complex instance and a
3934 Fractions instance now raise TypeError instead of returning True/False. This
3935 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3936 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004255- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00004256 is run with the -OO flag. Tests requiring docstrings are skipped.
4257
Georg Brandlba83f822010-03-14 09:50:54 +00004258- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4259 now also used by regrtest to run all the tests in a temporary directory. The
4260 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent

4278 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004279 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004293- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4294 and add the additional members returned in an OSVERSIONINFOEX structure. The
4295 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00004298- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4299 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4300 returning NULL. The macro now returns a statically allocated empty string
4301 instead.

4311 strings,
4312 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4313 numeric strings corresponding to subnormal values,
4314 (3) a memory leak for some values large enough to cause overflow, and
4315 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00004346- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004347 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004348 Also, raise ValueError rather than TypeError when an unknown TIPC address
4349 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004353- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004354 file position when calling `truncate()`. It would previously change the file
4355 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004356 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4357
Georg Brandlba83f822010-03-14 09:50:54 +00004358- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4359 class used to represent files stored inside an archive. The new
4360 implementation is significantly faster and can be wrapped in a
4361 ``io.BufferedReader`` object for more speedups. It also solves an issue
4362 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4363 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004373- Issue #7748: Since unicode values are supported for some metadata options in
4374 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4375 encoded string for them. This ensures that the upload and register commands
4376 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00004445What's New in Python 2.7 alpha 2?
4446=================================

4451-----------------
4452
Georg Brandlba83f822010-03-14 09:50:54 +00004453- The ``__complex__()`` method is now looked up on the class of instances to
4454 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004455
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004456- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4457 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4458
Mark Dickinson1b34d252010-01-01 17:27:30 +00004459- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004460 DeprecationWarning when passed a float argument where an integer was expected.
4461 These functions and methods now raise TypeError instead. The majority of the
4462 effects of this change are in the extension modules, but some core functions
4463 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4464 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00004465

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00004474- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
4475 used to drop the time part of the result.
4476
Georg Brandlba83f822010-03-14 09:50:54 +00004477- Issue #1811: Improve accuracy and cross-platform consistency for true division
4478 of integers: the result of a/b is now correctly rounded for ints a and b (at
4479 least on IEEE 754 platforms), and in particular does not depend on the
4480 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004481
Georg Brandlba83f822010-03-14 09:50:54 +00004482- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4483 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4484 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00004485

Ronald Oussoren92919a62009-12-24 13:30:58 +00004487 executables on OSX.
4488
Georg Brandlba83f822010-03-14 09:50:54 +00004489 These executables now work properly with the arch(1) command: ``arch -ppc
4490 python`` will start a universal binary version of python in PPC mode (unlike
4491 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00004492
Georg Brandlba83f822010-03-14 09:50:54 +00004493- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
4494 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00004495

Antoine Pitrou80157252010-01-08 19:20:17 +00004513- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00004514 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
4515 alternative to cPickle if you care about performance. Patch by Florent

Ezio Melotti569e61f2009-12-30 06:14:51 +00004535 Initial patch by Brian Curtin.
4536
Georg Brandlba83f822010-03-14 09:50:54 +00004537- Distutils now correctly identifies the build architecture as "x86_64" when

Benjamin Petersonddd392c2009-12-13 19:19:07 +00004550- Issue #7349: Make methods of file objects in the io module accept None as an
4551 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
4552 the same as passing no argument.
4553
Georg Brandlba83f822010-03-14 09:50:54 +00004554- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00004576- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
4577 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4578 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4579 float arguments for integer format codes (other than 'L'): previously an

4581 TypeError. For the 'L' format code (which previously had no warning) there is
4582 now a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00004647- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4648 decimal string that's guaranteed to round back to x under correct rounding
4649 (with round-half-to-even rounding mode). Previously it gave a string based on
4650 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4651 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4652 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004653
Georg Brandlba83f822010-03-14 09:50:54 +00004654- Issue #7117: On almost all platforms: float-to-string and string-to-float
4655 conversions within Python are now correctly rounded. Places these conversions
4656 occur include: str for floats and complex numbers; the float and complex
4657 constructors; old-style and new-style numeric formatting; serialization and
4658 deserialization of floats and complex numbers using marshal, pickle and json;
4659 parsing of float and imaginary literals in Python code; Decimal-to-float
4660 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004661
Georg Brandlba83f822010-03-14 09:50:54 +00004662 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4663 providing correctly-rounded strtod and dtoa C functions. This code is
4664 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4665 the C compiler. There may be a small number of platforms on which correct
4666 operation of this code cannot be guaranteed, so the code is not used: notably,
4667 this applies to platforms where the C double format is not IEEE 754 binary64,
4668 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4669 and Python's configure script is unable to determine how to change the FPU
4670 precision. On these platforms conversions use the platform strtod and dtoa,
4671 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004672
Georg Brandlba83f822010-03-14 09:50:54 +00004673- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4674 uses the correctly-rounded string <-> float conversions described above (when
4675 available), and so produces correctly rounded results that will display nicely
4676 under the float repr. There are two related small changes: (1) round now
4677 accepts any class with an ``__index__()`` method for its second argument (but
4678 no longer accepts floats for the second argument), and (2) an excessively
4679 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

4907 internal representation of integers, for performance reasons. Base 2**30 is
4908 enabled by default on 64-bit machines. Add --enable-big-digits option to
4909 configure, which overrides the default. Add sys.long_info structseq to
4910 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00004973- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4974 existing .py counterpart, override the co_filename attributes of all code

5030
Georg Brandlba83f822010-03-14 09:50:54 +00005031- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5032 file objects with closefd=False. The file descriptor is still kept open but
5033 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00005057- On windows, ``os.chdir()`` given unicode was not working if
5058 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5059 this code path is really executed because I cannot move to such directory on
5060 win2k)

5086 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006466- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6468 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6469 ``printf`` function, whereas PyString_FromFormat has an independent
6470 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006567 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6568 for catch_warnings() also led to an improvement in the raising of a
6569 DeprecationWarning related to warnings.warn_explicit().
6570

6593
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006594- Issue #2975: When compiling several extension modules with Visual Studio 2008

6596 without limit.
6597
Benjamin Peterson37346b22008-08-23 20:27:43 +00006598- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006635What's New in Python 2.6 beta 3?
6636================================
6637
Barry Warsaw07a4a382008-08-21 01:15:08 +00006638*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006639
6640Core and Builtins
6641-----------------
6642
Guido van Rossumf8402962008-08-20 15:01:50 +00006643- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6644 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6645 extensions do not automatically benefit from the class attribute
6646 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6647 to their tp_flags field if they care. This is a backwards
6648 compatibility feature; in 3.0, all types will use the cache by
6649 default.
6650
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006651- Keyword arguments can now follow starred arguments. (``f(a, *args,
6652 keyword=23)`` is now valid syntax.)
6653
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006654- ctypes function pointers that are COM methods have a boolean True
6655 value again.
6656
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006657- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6658 by denying s# to parse objects that have a releasebuffer procedure,
6659 and introducing s*.
6660
Georg Brandl1e13ea92008-08-11 09:07:59 +00006661- Issue #3537: Fix an assertion failure when an empty but presized dict
6662 object was stored in the freelist.
6663
Mark Dickinsonb6467572008-08-04 21:30:09 +00006664- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6665 ValueError consistently across platforms.
6666
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006667- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6668 (64bit Unix, for example), unichr() would truncate its argument and return
6669 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6670
Neal Norwitze7d8be82008-07-31 17:17:14 +00006671- Apply security patches from Apple.
6672
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006673- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6674 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6675
Antoine Pitrou92f82162008-07-25 22:22:08 +00006676- Issue #1819: function calls with several named parameters are now on
6677 average 35% faster (as measured by pybench).
6678
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006679- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6680 the python debugger steps into a class statement: the free variables (local
6681 variables defined in an outer scope) would be deleted from the outer scope.
6682
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006683- Issue #2620: Overflow checking when allocating or reallocating memory
6684 was not always being done properly in some python types and extension
6685 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6686 all been updated to perform better checks and places in the code that
6687 would previously leak memory on the error path when such an allocation
6688 failed have been fixed.

6694
Benjamin Petersone977ad42008-08-20 01:42:01 +00006695- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6696 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6697
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006698- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6699 version reported by these tools does not necessarily follow the python
6700 version numbering scheme, so the module is less strict when parsing it.
6701
Nick Coghlanf70385a2008-08-18 12:42:46 +00006702- Issue #2235: Added Py3k warnings for types which will become unhashable
6703 under the stricter __hash__ inheritance rules in 3.0. Several types
6704 which did not meet the rules for hash invariants and were already
6705 unhashable in 3.0 have now been explicitly flagged as unhashable in
6706 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6707 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6708
Brett Cannon88f801d2008-08-18 00:46:22 +00006709- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6717
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006718- Issue #3575: Incremental decoder's decode function now takes bytearray
6719 by using 's*' instead of 't#'.
6720
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006721- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006722 fails unicode conversion on 2nd parameter. (windows only)
6723
Georg Brandl222e2082010-08-01 22:27:39 +00006724- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006725 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00006728 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006729
Facundo Batistaeb90b782008-08-16 14:44:07 +00006730- Issue #2776: fixed small issue when handling an URL with double slash
6731 after a 302 response in the case of not going through a proxy.
6732
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006733- Issue #2676: in the email package, content-type parsing was hanging on
6734 pathological input because of quadratic or exponential behaviour of a
6735 regular expression.
6736
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006737- Issue #3476: binary buffered reading through the new "io" library is now
6738 thread-safe.
6739
Brett Cannonbf3157b2008-08-14 05:00:03 +00006740- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6741 since mimetools itself is deprecated. Because modules are cached, all
6742 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6743
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006744- Issue #3134: shutil referenced undefined WindowsError symbol.
6745
Robert Schuppenies14646332008-08-10 11:01:53 +00006746- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6747 menu entries were not deleted.
6748
Brett Cannon83e81842008-08-09 23:30:55 +00006749- Copied the implementation of reduce() to _functools.reduce() to have a
6750 version that did not raise a DeprecationWarning under -3.
6751
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006752- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6753 a MemoryError rather than silently stop the iteration.
6754
Guido van Rossum59ce9012008-08-09 14:55:34 +00006755- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6756 to _sre.compile() will now be rejected. This should not affect anybody
6757 since the re.compile() function never generates invalid re-bytecode.
6758
Skip Montanaroa032bf42008-08-08 22:52:51 +00006759- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

6761 it wasn't initialized during instantiation.
6762
Brett Cannon3aa2a492008-08-06 22:28:09 +00006763- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6764 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00006778 asking for a specific length. This problem only affected files opened
6779 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006780

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006829What's New in Python 2.6 beta 2?
6830================================
6831
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006832*Release date: 17-Jul-2008*
6833
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006834Core and Builtins
6835-----------------
6836
Georg Brandl3e483f62008-07-16 22:57:41 +00006837- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6838 its methods now allow for items objects that can be converted to
6839 an integer using operator.index().
6840
Mark Dickinson64b7e502008-07-16 09:40:03 +00006841- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6842 produced a ValueError instead of giving the correct float.
6843
Eric Smitha5fa5a22008-07-16 00:11:49 +00006844- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6845 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6846
Mark Dickinson7103aa42008-07-15 19:08:33 +00006847- Issue #3008: the float type has a new instance method 'float.hex'
6848 and a new class method 'float.fromhex' to convert floating-point
6849 numbers to and from hexadecimal strings, respectively.
6850
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006851- Issue #2235: __hash__ is once again inherited by default. To allow
6852 collections.Hashable to remain meaningful in the presence of the
6853 default hash implementation (object.__hash__), it is now possible
6854 to explicit block inheritance of hash by setting __hash__=None at
6855 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6856 level.
6857
Nick Coghlanb028f502008-07-13 14:52:36 +00006858- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6859 the parent module cannot be found while performing an absolute import.
6860 This means that an incorrectly defined __package__ attribute will
6861 now only prevent relative imports in that module rather than causing
6862 all imports from that module to fail.
6863
Nick Coghlan14ff9942008-07-08 14:21:42 +00006864- Issue #2517: Allow unicode messages in Exceptions again by correctly
6865 bypassing the instance dictionary when looking up __unicode__ on
6866 new-style classes.
6867
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006868- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6869 set to a custom object whose write() method happens to install
6870 another file in sys.stdout.
6871
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006872- Issue #3088: Corrected a race condition in classes derived from
6873 threading.local: the first member set by a thread could be saved in
6874 another thread's dictionary.
6875
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006876- Issue #3004: Minor change to slice.indices(): the start and stop
6877 arguments are now treated identically, making the behaviour easier
6878 to describe and understand. For example, slice(None, -10,
6879 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6880 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6881 10, -1).
6882
Georg Brandl278fc502008-07-19 12:46:12 +00006883- Issue #3219: Calling a function with repeated keyword arguments,
6884 f(a=2, a=23), would not cause a syntax error. This was a regression
6885 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006886
Georg Brandl278fc502008-07-19 12:46:12 +00006887- Issue #2862: Make int and float freelist management consistent with
6888 other freelists. Changes their CompactFreeList apis into
6889 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006890
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006891Library
6892-------
6893
Thomas Heller57adf222008-08-14 19:10:48 +00006894- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6895 api functions without holding the GIL, which could lead to a fatal
6896 error when they failed.
6897
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006898- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
6899

6905
Jesse Noller13e9d582008-07-16 14:32:36 +00006906- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6907 ForkingPickler.register() to resolve conflict with ctypes.
6908
Vinay Sajip51e65192008-07-18 09:01:10 +00006909- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006910
Thomas Heller880f5292008-07-15 19:39:38 +00006911- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6912 a valid dlerror() message.
6913
Thomas Heller2bad6572008-07-15 17:19:50 +00006914- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6915 incomplete structure was created.
6916
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006917- Issue #3339: dummy_thread.acquire() should not return None.
6918
Raymond Hettingerb01713e2008-07-10 14:34:57 +00006919- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
6920
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006921- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006922
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006923- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6924 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006925 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006926 content-length. The problem had been corrected in the 2.4 branch, but never
6927 merged into trunk.
6928
Georg Brandle78fbcc2008-07-05 10:13:36 +00006929- Issue #2663: add filtering capability to shutil.copytree().
6930

6932
6933- Issue #1526: Allow more than 64k files to be added to Zip64 file.
6934
6935- Issue #1746: Correct handling of zipfile archive comments (previously
6936 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00006937 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00006938
Vinay Sajip51e65192008-07-18 09:01:10 +00006939- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006940 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006941
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006942- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6943 handling is now the same as that of other special attributes like __name__).
6944
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006945- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6946 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007397- Issue #1631171: Re-implement the 'warnings' module in C (the
7398 original Python code has been kept as backup). This will allow for
7399 using the 'warning's machinery in such places as the parser where
7400 use of pure Python code is not possible. Both the ``showarning()``
7401 and ``formatwarning()`` gain an optional 'line' argument which is
7402 not called by default for backwards-compatibility reasons. Setting
7403 ``warnings.showwarning()`` to an implementation that lacks support
7404 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007467- Issue #2550: The approach used by client/server code for obtaining
7468 ports to listen on in network-oriented tests has been refined in an
7469 effort to facilitate running multiple instances of the entire
7470 regression test suite in parallel without issue.
7471 test_support.bind_port() has been fixed such that it will always
7472 return a unique port -- which wasn't always the case with the
7473 previous implementation, especially if socket options had been set
7474 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7475 new implementation of bind_port() will actually raise an exception
7476 if it is passed an AF_INET/SOCK_STREAM socket with either the
7477 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7478 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7479 the socket it's been passed. This currently only applies to
7480 Windows. This option prevents any other sockets from binding to the
7481 host/port we've bound to, thus removing the possibility of the
7482 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7483 when a second SOCK_STREAM socket binds and accepts to a host/port
7484 that's already been bound by another socket. The optional preferred
7485 port parameter to bind_port() has been removed. Under no
7486 circumstances should tests be hard coding ports!
7487
7488 test_support.find_unused_port() has also been introduced, which will
7489 pass a temporary socket object to bind_port() in order to obtain an
7490 unused port. The temporary socket object is then closed and
7491 deleted, and the port is returned. This method should only be used
7492 for obtaining an unused port in order to pass to an external program
7493 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7494 a parameter to a server-oriented class that doesn't give you direct
7495 access to the underlying socket used.
7496
7497 Finally, test_support.HOST has been introduced, which should be used
7498 for the host argument of any relevant socket calls (i.e. bind and
7499 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007500
7501 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007502 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

7663 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00007664 platform.machine() and platform.processor() will report this
7665 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00007786- Added the future_builtins module, which contains hex() and oct().
7787 These are the PEP 3127 version of these functions, designed to be
7788 compatible with the hex() and oct() builtins from Python 3.0. They
7789 differ slightly in their output formats from the existing, unchanged
7790 Python 2.6 builtins. The expected usage of the future_builtins
7791 module is:
7792 from future_builtins import hex, oct
7793
Eric Smith7ef40bf2008-02-20 23:34:22 +00007794- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7795 exponents for exponents with absolute value < 100. Follows C99
7796 standard. This is a change on Windows, which would use 3 digits.
7797 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7798 so that any alterations it does to the resulting string will be
7799 available in stringlib/formatter.h (for float.__format__).
7800
Eric Smith5a3c1352008-02-19 13:21:56 +00007801- Implemented PEP 3101, Advanced String Formatting. This adds a new
7802 builtin format(); a format() method for str and unicode; a
7803 __format__() method to object, str, unicode, int, long, float, and
7804 datetime; the class string.Formatter; and the C API
7805 PyObject_Format().
7806
Georg Brandl3ee81df2008-05-17 18:14:43 +00007807- Fixed several potential crashes, all caused by specially crafted
7808 __del__ methods exploiting objects in temporarily inconsistent
7809 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007810
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007811- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007812 prevent a possible crash: an Abstract Base Class would try to access
7813 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007814

Georg Brandl3ee81df2008-05-17 18:14:43 +00007818- Clear all free lists during a gc.collect() of the highest generation
7819 in order to allow pymalloc to free more arenas. Python may give back
7820 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007821
Georg Brandl3ee81df2008-05-17 18:14:43 +00007822- Issue #2045: Fix an infinite recursion triggered when printing a
7823 subclass of collections.defaultdict, if its default_factory is set
7824 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007825
Christian Heimesf75dbef2008-02-08 00:11:31 +00007826- Fixed a minor memory leak in dictobject.c. The content of the free
7827 list was not freed on interpreter shutdown.
7828
Georg Brandl21e99f42010-03-07 15:23:59 +00007829- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007830 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007831
Georg Brandl3ee81df2008-05-17 18:14:43 +00007832- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7833 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007834 to compact the internal free lists of pre-allocted ints and floats.
7835
Georg Brandl3ee81df2008-05-17 18:14:43 +00007836- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7837 calls. Python expected the return type int but the fork familie
7838 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007839
Georg Brandl3ee81df2008-05-17 18:14:43 +00007840- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00007852- Patch #1473257: generator objects gain a gi_code attribute. This is
7853 the same object as the func_code attribute of the function that
7854 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007855
Georg Brandl3ee81df2008-05-17 18:14:43 +00007856- Issue #1920: "while 0" statements were completely removed by the
7857 compiler, even in the presence of an "else" clause, which is
7858 supposed to be run when the condition is false. Now the compiler
7859 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007860
Guido van Rossumeead05f2008-01-24 18:21:02 +00007861- A few crashers fixed: weakref_in_del.py (issue #1377858);
7862 loosing_dict_ref.py (issue #1303614, test67.py);
7863 borrowed_ref_[34].py (not in tracker).
7864

7868
Georg Brandl3ee81df2008-05-17 18:14:43 +00007869- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007870 several extension methods and modules do not work without unicode
7871 support.
7872
Georg Brandl26543b12008-01-21 18:36:51 +00007873- Issue #1882: when compiling code from a string, encoding cookies in the
7874 second line of code were not always recognized correctly.
7875
Georg Brandl14404b62008-01-19 19:27:05 +00007876- Issue #1679: "0x" was taken as a valid integer literal.
7877
Georg Brandl6caad7d2008-01-26 14:19:22 +00007878- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007879 added.
7880
Christian Heimesc94e2b52008-01-14 04:13:37 +00007881- sys.float_info / PyFloat_GetInfo: The floating point information
7882 object was converted from a dict to a specialized structseq object.
7883
Georg Brandl3ee81df2008-05-17 18:14:43 +00007884- Patch #1816: Added sys.flags structseq. It exposes the status of
7885 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007886
Georg Brandl3ee81df2008-05-17 18:14:43 +00007887- Objects/structseq.c: Implemented new structseq representation. The
7888 patch makes structseqs (e.g. the return value of os.stat) more
7889 readable.

7898
Georg Brandl3ee81df2008-05-17 18:14:43 +00007899- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7900 envvar and sys.dont_write_bytecode attribute. All these can be set
7901 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007902
Georg Brandl3ee81df2008-05-17 18:14:43 +00007903- Improve some exception messages when Windows fails to load an
7904 extension module. Now we get for example '%1 is not a valid Win32
7905 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007912- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007913 and INF. float("nan"), float("inf") and float("-inf") now work on
7914 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007916- Compiler now generates simpler and faster code for dictionary
7917 literals. The oparg for BUILD_MAP now indicates an estimated
7918 dictionary size. There is a new opcode, STORE_MAP, for adding
7919 entries to the dictionary.

7949 file can now be directly executed by passing their name to the
7950 interpreter. The directory/zipfile is automatically inserted as the
7951 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007953- Issue #1265: Fix a problem with sys.settrace, if the tracing
7954 function uses a generator expression when at the same time the
7955 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007956
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007957- sets and frozensets now have an isdisjoint() method.

7962
Georg Brandl21e99f42010-03-07 15:23:59 +00007963- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007964 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7965 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007966
Georg Brandl3ee81df2008-05-17 18:14:43 +00007967- Issue #1686386: Tuple's tp_repr did not take into account the
7968 possibility of having a self-referential tuple, which is possible
7969 from C code. Nor did object's tp_str consider that a type's tp_str
7970 could do something that could lead to an inifinite recursion.
7971 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7972 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007973
Georg Brandl3ee81df2008-05-17 18:14:43 +00007974- Issue #1164: It was possible to trigger deadlock when using the
7975 'print' statement to write to a file since the GIL was not released
7976 as needed. Now PyObject_Print() does the right thing along with
7977 various tp_print implementations of the built-in types and those in
7978 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007979
Georg Brandl3ee81df2008-05-17 18:14:43 +00007980- Issue #1147: Exceptions were directly allowing string exceptions in
7981 their throw() method even though string exceptions no longer
7982 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007983
Georg Brandl3ee81df2008-05-17 18:14:43 +00007984- Issue #1096: Prevent a segfault from getting the repr of a very
7985 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007986
Brett Cannon1e534b52007-09-07 04:18:30 +00007987- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007988 PyObject_Call() never calling back out to Python code to trigger
7989 recursion depth updates/checks. Required the creation of a static
7990 RuntimeError instance in case normalizing an exception put the
7991 recursion check value past its limit. Fixes crashers
7992 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007993

Neal Norwitz0ac60192007-05-27 04:08:54 +00008007- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008008 __*__ attributes. (Some already existed, e.g., __doc__ and
8009 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008010
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008011- Add -3 option to the interpreter to warn about features that are
8012 deprecated and will be changed/removed in Python 3.0.
8013
Georg Brandl2134e752007-05-21 20:34:16 +00008014- Patch #1686487: you can now pass any mapping after '**' in function
8015 calls.
8016
Collin Winter62903052007-05-18 23:11:24 +00008017- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008018 "except E as target:". This is to provide forwards compatibility
8019 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008020
Brett Cannon229cee22007-05-05 01:34:02 +00008021- Deprecate BaseException.message as per PEP 352.
8022
Georg Brandl3ee81df2008-05-17 18:14:43 +00008023- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00008026- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008027 setting a plain string, ie don't expand to single letter identifiers.
8028
Raymond Hettinger13936692007-04-11 18:40:58 +00008029- Request #1191699: Slices can now be pickled.
8030
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008031- Request #1193128: str.translate() now allows a None argument for
8032 translations that only remove characters without re-mapping the
8033 remaining characters.
8034
Georg Brandl5cb76c12007-03-21 09:00:39 +00008035- Patch #1682205: a TypeError while unpacking an iterable is no longer

8039
Guido van Rossum143b5642007-03-23 04:58:42 +00008040- Bug #1683368: The object.__init__() and object.__new__() methods are
8041 now stricter in rejecting excess arguments. The only time when
8042 either allows excess arguments is when it is not overridden and the
8043 other one is. For backwards compatibility, when both are
8044 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008045 warning later). Also, type.__init__() insists on the same signature
8046 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008047
Georg Brandl3ee81df2008-05-17 18:14:43 +00008048- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8049 object to complex using its __complex__() method before falling back
8050 to the __float__() method. Therefore, the functions in the cmath
8051 module now can operate on objects that define a __complex__()
8052 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008053
Georg Brandl3ee81df2008-05-17 18:14:43 +00008054- Patch #1623563: allow __class__ assignment for classes with
8055 __slots__. The old and the new class are still required to have the
8056 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008057

8062 ``object.__reduce_ex__()`` is called with an object that is faking
8063 its type.

8069
Georg Brandl7b9c5552007-03-12 14:30:05 +00008070- Bug #1678647: write a newline after printing an exception in any
8071 case, even when converting the value to a string failed.
8072
Georg Brandl871f1bc2007-03-12 13:17:36 +00008073- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008074 its argument, if it exists. If not, it will work like before. This
8075 allows customizing the output of dir() in the presence of a
8076 __getattr__().

8080
Georg Brandl3ee81df2008-05-17 18:14:43 +00008081- Patch #1675981: remove unreachable code from ``type.__new__()``

8085 parthensized forms. This means complex(repr(x)) now works instead of
8086 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008087
Georg Brandlaa2321b2007-03-07 00:40:28 +00008088- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008089 makes the filenames the warning module prints much more sensible
8090 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008091

Georg Brandl0fca97a2007-03-05 22:28:08 +00008103- Patch #1674228: when assigning a slice (old-style), check for the
8104 sq_ass_slice instead of the sq_slice slot.
8105
Georg Brandl3ee81df2008-05-17 18:14:43 +00008106- When printing an unraisable error, don't print exceptions. before
8107 the name. This duplicates the behavior whening normally printing
8108 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008641 AttributeError instead of an IOError when the server's response
8642 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008643

Georg Brandl3ee81df2008-05-17 18:14:43 +00008659- Patch #1530482: add pydoc.render_doc() which returns the

8674
Georg Brandl92a6bae2007-03-13 17:43:32 +00008675- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008676 are set for invalid interpolation sequences that would lead to
8677 errors on reading back those values.

8720 returned string up to the first NUL character.

8733 TestCase and TestSuite subclasses (not instances) are no longer
8734 accepted in TestSuite.addTest(). This should cause no
8735 incompatibility since it never made sense with ordinary subclasses
8736 -- the failure just occurred later, with a more cumbersome
8737 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009018 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009119- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009120 time so that opening a database previously created with the DB_DUP
9121 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9122 opens. Specifically: dictionary assignment to a DB object will
9123 replace all values for a given key when the database allows
9124 duplicate values. DB users should use DB.put(k, v) when they want
9125 to store duplicates; not DB[k] = v.

9490 of w# format code incorrectly truncated the length to an int, even
9491 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9492 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009522- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9523 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
