Gregory P. Smith7902f8d2014-01-06 09:50:19 -080012- Issue #19081: When a zipimport .zip file in sys.path being imported from
13 is modified during the lifetime of the Python process after zipimport has
14 already cached the zip's table of contents we detect this and recover
15 rather than read bad data from the .zip (causing odd import errors).
16

25 state. Fix a crash when a generator is created in a C thread that is
26 destroyed while the generator is still used. The issue was that a generator
27 contains a frame, and the frame kept a reference to the Python state of the
28 destroyed C thread. The crash occurs when a trace function is setup.

1564 In particular, fix extension module build failures when trying to use
1565 32-bit-only installer Pythons on systems with Xcode 4 (currently
1566 OS X 10.8, 10.7, and optionally 10.6).
1567 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1568 * Since Xcode 4 removes ppc support, extension module builds now
1569 check for ppc compiler support and by default remove ppc and
1570 ppc64 archs when they are not available.
1571 * Extension module builds now revert to using system installed
1572 headers and libs (/usr and /System/Library) if the SDK used
1573 to build the interpreter is not installed or has moved.
1574 * Try to avoid building extension modules with deprecated
1575 and problematic Apple llvm-gcc compiler. If original compiler
1576 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01002007- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2008 Distutils-based packages with C extension modules may fail because
2009 Apple has removed gcc-4.2, the version used to build python.org
2010 64-bit/32-bit Pythons. If the user does not explicitly override
2011 the default C compiler by setting the CC environment variable,
2012 Distutils will now attempt to compile extension modules with clang
2013 if gcc-4.2 is required but not found. Also as a convenience, if
2014 the user does explicitly set CC, substitute its value as the default
2015 compiler in the Distutils LDSHARED configuration variable for OS X.
2016 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2017 SDK, neither of which are available in Xcode 4. This change does not
2018 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002268- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2269 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2270 interpreter process. This could cause failures in non-Distutils subprocesses
2271 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002272 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002273 deployment target only in the environment of each build subprocess. It is
2274 still possible to globally override the default by setting
2275 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2276 greater or equal to the default value, the value with which the interpreter
2277 was built.

2307 the ticker doesn't have to wind down to zero from the old starting point
2308 before the new interval takes effect. And if the user increases the
2309 interval, it makes sure the new limit takes effect right away rather have an
2310 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003290- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3291 This prevents user-created self-referencing ordered dictionaries from
3292 becoming permanently uncollectable GC garbage. The downside is that
3293 removing __del__ means that the internal doubly-linked list has to wait for
3294 GC collection rather than freeing memory immediately when the refcnt drops
3295 to zero.
3296
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003297- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3300
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003301- Issue #9792: In case of connection failure, socket.create_connection()
3302 would swallow the exception and raise a new one, making it impossible
3303 to fetch the original errno, or to filter timeout errors. Now the
3304 original error is re-raised.
3305
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003306- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

3325
R. David Murray7c4bf552010-08-25 01:45:57 +00003326- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3327 character years even if the message contains RFC822 two character years.
3328
Daniel Stutzbach91287322010-08-24 21:09:30 +00003329- Issue #8750: Fixed MutableSet's methods to correctly handle

3342
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003343- Issue #9617: Signals received during a low-level write operation aren't
3344 ignored by the buffered IO layer anymore.
3345
Benjamin Peterson52c36052010-08-21 03:03:22 +00003346- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

3348
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003349- Issue #9626: the view methods for collections.OrderedDict() were returning

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003361- Issue #9550: a BufferedReader could issue an additional read when the
3362 original read request had been satisfied, which could block indefinitely
3363 when the underlying raw IO channel was e.g. a socket. Report and original
3364 patch by Jason V. Miller.
3365
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003366- Issue #9551: Don't raise TypeError when setting the value to None for

3395 does not contain a '-', instead of raising an error.
3396

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004139- Issue #7301: Add environment variable $PYTHONWARNINGS.
4140
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004141- Issue #8329: Don't return the same lists from select.select when no fds are
4142 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00004144- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004145 on 64-bit machines. The shift count for either left or right shift is
4146 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00004154- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4155 with a non-empty format string. This is an effort to future-proof user
4156 code. If a derived class does not currently implement __format__ but later
4157 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004158 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004159 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004209- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4210 InvalidOperation instead of returning False. (Comparisons involving a quiet
4211 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4212 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004213
Georg Brandlfee0f442010-05-22 21:26:21 +00004214- Issue #2531: Comparison operations between floats and Decimal instances now
4215 return a result based on the numeric values of the operands; previously they
4216 returned an arbitrary result based on the relative ordering of id(float) and
4217 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00004231- Comparisons using one of <, <=, >, >= between a complex instance and a
4232 Fractions instance now raise TypeError instead of returning True/False. This
4233 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4234 <=> complex, and complex <=> complex comparisons.

4597 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4598 returning NULL. The macro now returns a statically allocated empty string
4599 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004645 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004651- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004652 file position when calling `truncate()`. It would previously change the file
4653 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004654 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4655

4657 class used to represent files stored inside an archive. The new
4658 implementation is significantly faster and can be wrapped in a
4659 ``io.BufferedReader`` object for more speedups. It also solves an issue
4660 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004671- Issue #7748: Since unicode values are supported for some metadata options in
4672 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4673 encoded string for them. This ensures that the upload and register commands
4674 send the correct values to PyPI without any error.

4749-----------------
4750
Georg Brandlba83f822010-03-14 09:50:54 +00004751- The ``__complex__()`` method is now looked up on the class of instances to
4752 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004753
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004754- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4755 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4756
Mark Dickinson1b34d252010-01-01 17:27:30 +00004757- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004758 DeprecationWarning when passed a float argument where an integer was expected.
4759 These functions and methods now raise TypeError instead. The majority of the
4760 effects of this change are in the extension modules, but some core functions
4761 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4762 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00004763

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00004772- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
4773 used to drop the time part of the result.
4774
Georg Brandlba83f822010-03-14 09:50:54 +00004775- Issue #1811: Improve accuracy and cross-platform consistency for true division
4776 of integers: the result of a/b is now correctly rounded for ints a and b (at
4777 least on IEEE 754 platforms), and in particular does not depend on the
4778 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004779
Georg Brandlba83f822010-03-14 09:50:54 +00004780- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4781 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4782 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00004783

Ronald Oussoren92919a62009-12-24 13:30:58 +00004785 executables on OSX.
4786
Georg Brandlba83f822010-03-14 09:50:54 +00004787 These executables now work properly with the arch(1) command: ``arch -ppc
4788 python`` will start a universal binary version of python in PPC mode (unlike
4789 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00004790
Georg Brandlba83f822010-03-14 09:50:54 +00004791- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

4803 allowing for a maximum number of tasks within the pool to be completed by the
4804 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00004810- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00004811 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
4812 alternative to cPickle if you care about performance. Patch by Florent

4848 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
4849 the same as passing no argument.
4850
Georg Brandlba83f822010-03-14 09:50:54 +00004851- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00004944- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4945 decimal string that's guaranteed to round back to x under correct rounding
4946 (with round-half-to-even rounding mode). Previously it gave a string based on
4947 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4948 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4949 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004950
Georg Brandlba83f822010-03-14 09:50:54 +00004951- Issue #7117: On almost all platforms: float-to-string and string-to-float
4952 conversions within Python are now correctly rounded. Places these conversions
4953 occur include: str for floats and complex numbers; the float and complex
4954 constructors; old-style and new-style numeric formatting; serialization and
4955 deserialization of floats and complex numbers using marshal, pickle and json;
4956 parsing of float and imaginary literals in Python code; Decimal-to-float
4957 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004958
Georg Brandlba83f822010-03-14 09:50:54 +00004959 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4960 providing correctly-rounded strtod and dtoa C functions. This code is
4961 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4962 the C compiler. There may be a small number of platforms on which correct
4963 operation of this code cannot be guaranteed, so the code is not used: notably,
4964 this applies to platforms where the C double format is not IEEE 754 binary64,
4965 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4966 and Python's configure script is unable to determine how to change the FPU
4967 precision. On these platforms conversions use the platform strtod and dtoa,
4968 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004969
Georg Brandlba83f822010-03-14 09:50:54 +00004970- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4971 uses the correctly-rounded string <-> float conversions described above (when
4972 available), and so produces correctly rounded results that will display nicely
4973 under the float repr. There are two related small changes: (1) round now
4974 accepts any class with an ``__index__()`` method for its second argument (but
4975 no longer accepts floats for the second argument), and (2) an excessively
4976 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4977 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005195 untrackable objects are not tracked by the garbage collector. This can reduce
5196 the size of collections and therefore the garbage collection overhead on
5197 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00005203- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
5204 internal representation of integers, for performance reasons. Base 2**30 is
5205 enabled by default on 64-bit machines. Add --enable-big-digits option to
5206 configure, which overrides the default. Add sys.long_info structseq to
5207 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00005270- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5271 existing .py counterpart, override the co_filename attributes of all code
5272 objects if the original filename is obsolete (which can happen if the file has

5327
Georg Brandlba83f822010-03-14 09:50:54 +00005328- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5329 file objects with closefd=False. The file descriptor is still kept open but
5330 the file object behaves like a closed file. The ``FileIO`` object also got a
5331 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005351- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005354- On windows, ``os.chdir()`` given unicode was not working if
5355 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5356 this code path is really executed because I cannot move to such directory on
5357 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005359- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5360 element is temporarily replaced with an equivalent frozenset. But the
5361 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005382- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5383 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5384 step. This avoids problems with counting UTF-8 bytes that ignores the effect

5386
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005387- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00006560 - If x is not an int, long or float, then packing x will always result in
6561 struct.error. Previously an x with an __int__ method could be packed by
6562 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6563 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6564 neither __int__ nor __long__, TypeError used to be raised (with a
6565 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6566 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00006567
Georg Brandlba83f822010-03-14 09:50:54 +00006568 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
6569 argument with an __int__ method can be packed, but use of this feature
6570 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006763- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6765 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Brett Cannon1eaf0742008-09-02 01:25:16 +00006864 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6865 for catch_warnings() also led to an improvement in the raising of a
6866 DeprecationWarning related to warnings.warn_explicit().
6867

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006932What's New in Python 2.6 beta 3?
6933================================
6934
Barry Warsaw07a4a382008-08-21 01:15:08 +00006935*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006936
6937Core and Builtins
6938-----------------
6939
Guido van Rossumf8402962008-08-20 15:01:50 +00006940- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6941 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6942 extensions do not automatically benefit from the class attribute
6943 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6944 to their tp_flags field if they care. This is a backwards
6945 compatibility feature; in 3.0, all types will use the cache by
6946 default.
6947
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006948- Keyword arguments can now follow starred arguments. (``f(a, *args,
6949 keyword=23)`` is now valid syntax.)
6950
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006951- ctypes function pointers that are COM methods have a boolean True
6952 value again.
6953
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006954- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6955 by denying s# to parse objects that have a releasebuffer procedure,
6956 and introducing s*.
6957
Georg Brandl1e13ea92008-08-11 09:07:59 +00006958- Issue #3537: Fix an assertion failure when an empty but presized dict
6959 object was stored in the freelist.
6960
Mark Dickinsonb6467572008-08-04 21:30:09 +00006961- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6962 ValueError consistently across platforms.
6963
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006964- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6965 (64bit Unix, for example), unichr() would truncate its argument and return
6966 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6967
Neal Norwitze7d8be82008-07-31 17:17:14 +00006968- Apply security patches from Apple.
6969
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006970- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6971 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6972
Antoine Pitrou92f82162008-07-25 22:22:08 +00006973- Issue #1819: function calls with several named parameters are now on
6974 average 35% faster (as measured by pybench).
6975
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006976- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6977 the python debugger steps into a class statement: the free variables (local
6978 variables defined in an outer scope) would be deleted from the outer scope.
6979
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006980- Issue #2620: Overflow checking when allocating or reallocating memory
6981 was not always being done properly in some python types and extension
6982 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6983 all been updated to perform better checks and places in the code that
6984 would previously leak memory on the error path when such an allocation
6985 failed have been fixed.

6991
Benjamin Petersone977ad42008-08-20 01:42:01 +00006992- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6993 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6994
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006995- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6996 version reported by these tools does not necessarily follow the python
6997 version numbering scheme, so the module is less strict when parsing it.
6998
Nick Coghlanf70385a2008-08-18 12:42:46 +00006999- Issue #2235: Added Py3k warnings for types which will become unhashable
7000 under the stricter __hash__ inheritance rules in 3.0. Several types
7001 which did not meet the rules for hash invariants and were already
7002 unhashable in 3.0 have now been explicitly flagged as unhashable in
7003 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7004 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7005
Brett Cannon88f801d2008-08-18 00:46:22 +00007006- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

7014
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007015- Issue #3575: Incremental decoder's decode function now takes bytearray
7016 by using 's*' instead of 't#'.
7017
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007018- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007019 fails unicode conversion on 2nd parameter. (windows only)
7020
Georg Brandl222e2082010-08-01 22:27:39 +00007021- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007022 in a redirect.

Brett Cannon721b1452008-08-16 22:00:27 +00007025 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007026
Facundo Batistaeb90b782008-08-16 14:44:07 +00007027- Issue #2776: fixed small issue when handling an URL with double slash
7028 after a 302 response in the case of not going through a proxy.
7029
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007030- Issue #2676: in the email package, content-type parsing was hanging on
7031 pathological input because of quadratic or exponential behaviour of a
7032 regular expression.
7033
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007034- Issue #3476: binary buffered reading through the new "io" library is now
7035 thread-safe.
7036
Brett Cannonbf3157b2008-08-14 05:00:03 +00007037- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7038 since mimetools itself is deprecated. Because modules are cached, all
7039 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7040
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007041- Issue #3134: shutil referenced undefined WindowsError symbol.
7042
Robert Schuppenies14646332008-08-10 11:01:53 +00007043- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7044 menu entries were not deleted.
7045
Brett Cannon83e81842008-08-09 23:30:55 +00007046- Copied the implementation of reduce() to _functools.reduce() to have a
7047 version that did not raise a DeprecationWarning under -3.
7048
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007049- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7050 a MemoryError rather than silently stop the iteration.
7051
Guido van Rossum59ce9012008-08-09 14:55:34 +00007052- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7053 to _sre.compile() will now be rejected. This should not affect anybody
7054 since the re.compile() function never generates invalid re-bytecode.
7055
Skip Montanaroa032bf42008-08-08 22:52:51 +00007056- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7057 upon first access it can be automatically initialized from the csv file if
7058 it wasn't initialized during instantiation.
7059
Brett Cannon3aa2a492008-08-06 22:28:09 +00007060- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7061 the reload() built-in has been removed.
7062
Brett Cannon7e30b672008-08-04 21:52:25 +00007063- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007075 asking for a specific length. This problem only affected files opened
7076 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007077

7118 interaction with the tp_hash slot (added in 2.6b2) are now documented
7119
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007120- Issue #643841: The language reference now provides more detailed
7121 coverage of the lookup process for special methods. The disclaimers
7122 regarding lack of coverage of new-style classes have also been
7123 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007126What's New in Python 2.6 beta 2?
7127================================
7128
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007129*Release date: 17-Jul-2008*
7130
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007131Core and Builtins
7132-----------------
7133
Georg Brandl3e483f62008-07-16 22:57:41 +00007134- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7135 its methods now allow for items objects that can be converted to
7136 an integer using operator.index().
7137
Mark Dickinson64b7e502008-07-16 09:40:03 +00007138- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7139 produced a ValueError instead of giving the correct float.
7140
Eric Smitha5fa5a22008-07-16 00:11:49 +00007141- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7142 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7143
Mark Dickinson7103aa42008-07-15 19:08:33 +00007144- Issue #3008: the float type has a new instance method 'float.hex'
7145 and a new class method 'float.fromhex' to convert floating-point
7146 numbers to and from hexadecimal strings, respectively.
7147
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007148- Issue #2235: __hash__ is once again inherited by default. To allow
7149 collections.Hashable to remain meaningful in the presence of the
7150 default hash implementation (object.__hash__), it is now possible
7151 to explicit block inheritance of hash by setting __hash__=None at
7152 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7153 level.
7154
Nick Coghlanb028f502008-07-13 14:52:36 +00007155- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7156 the parent module cannot be found while performing an absolute import.
7157 This means that an incorrectly defined __package__ attribute will
7158 now only prevent relative imports in that module rather than causing
7159 all imports from that module to fail.
7160
Nick Coghlan14ff9942008-07-08 14:21:42 +00007161- Issue #2517: Allow unicode messages in Exceptions again by correctly
7162 bypassing the instance dictionary when looking up __unicode__ on
7163 new-style classes.
7164
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007165- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7166 set to a custom object whose write() method happens to install
7167 another file in sys.stdout.
7168
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007169- Issue #3088: Corrected a race condition in classes derived from
7170 threading.local: the first member set by a thread could be saved in
7171 another thread's dictionary.
7172
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007173- Issue #3004: Minor change to slice.indices(): the start and stop
7174 arguments are now treated identically, making the behaviour easier
7175 to describe and understand. For example, slice(None, -10,
7176 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7177 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7178 10, -1).
7179
Georg Brandl278fc502008-07-19 12:46:12 +00007180- Issue #3219: Calling a function with repeated keyword arguments,
7181 f(a=2, a=23), would not cause a syntax error. This was a regression
7182 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007183
Georg Brandl278fc502008-07-19 12:46:12 +00007184- Issue #2862: Make int and float freelist management consistent with
7185 other freelists. Changes their CompactFreeList apis into
7186 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007187

7189-------
7190
Thomas Heller57adf222008-08-14 19:10:48 +00007191- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7192 api functions without holding the GIL, which could lead to a fatal
7193 error when they failed.
7194
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007195- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00007203- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7204 ForkingPickler.register() to resolve conflict with ctypes.
7205
Vinay Sajip51e65192008-07-18 09:01:10 +00007206- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00007207
Thomas Heller880f5292008-07-15 19:39:38 +00007208- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7209 a valid dlerror() message.
7210
Thomas Heller2bad6572008-07-15 17:19:50 +00007211- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7212 incomplete structure was created.
7213
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007214- Issue #3339: dummy_thread.acquire() should not return None.
7215
Raymond Hettingerb01713e2008-07-10 14:34:57 +00007216- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
7217
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007218- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007219
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007220- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7221 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007222 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007223 content-length. The problem had been corrected in the 2.4 branch, but never
7224 merged into trunk.
7225
Georg Brandle78fbcc2008-07-05 10:13:36 +00007226- Issue #2663: add filtering capability to shutil.copytree().

7232- Issue #1746: Correct handling of zipfile archive comments (previously
7233 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00007234 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00007235
Vinay Sajip51e65192008-07-18 09:01:10 +00007236- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007237 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007238
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007239- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7240 handling is now the same as that of other special attributes like __name__).
7241
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007242- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
7243 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007691- Issue #1631171: Re-implement the 'warnings' module in C (the
7692 original Python code has been kept as backup). This will allow for
7693 using the 'warning's machinery in such places as the parser where
7694 use of pure Python code is not possible. Both the ``showarning()``
7695 and ``formatwarning()`` gain an optional 'line' argument which is
7696 not called by default for backwards-compatibility reasons. Setting
7697 ``warnings.showwarning()`` to an implementation that lacks support
7698 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007761- Issue #2550: The approach used by client/server code for obtaining
7762 ports to listen on in network-oriented tests has been refined in an
7763 effort to facilitate running multiple instances of the entire
7764 regression test suite in parallel without issue.
7765 test_support.bind_port() has been fixed such that it will always
7766 return a unique port -- which wasn't always the case with the
7767 previous implementation, especially if socket options had been set
7768 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7769 new implementation of bind_port() will actually raise an exception
7770 if it is passed an AF_INET/SOCK_STREAM socket with either the
7771 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7772 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7773 the socket it's been passed. This currently only applies to
7774 Windows. This option prevents any other sockets from binding to the
7775 host/port we've bound to, thus removing the possibility of the
7776 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7777 when a second SOCK_STREAM socket binds and accepts to a host/port
7778 that's already been bound by another socket. The optional preferred
7779 port parameter to bind_port() has been removed. Under no
7780 circumstances should tests be hard coding ports!
7781
7782 test_support.find_unused_port() has also been introduced, which will
7783 pass a temporary socket object to bind_port() in order to obtain an
7784 unused port. The temporary socket object is then closed and
7785 deleted, and the port is returned. This method should only be used
7786 for obtaining an unused port in order to pass to an external program
7787 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7788 a parameter to a server-oriented class that doesn't give you direct
7789 access to the underlying socket used.
7790
7791 Finally, test_support.HOST has been introduced, which should be used
7792 for the host argument of any relevant socket calls (i.e. bind and
7793 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007794
7795 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007796 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007797 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7798 test_asynchat and test_socket_ssl.
7799
Georg Brandl3ee81df2008-05-17 18:14:43 +00007800 It is now possible for multiple instances of the regression test
7801 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008080- Added the future_builtins module, which contains hex() and oct().
8081 These are the PEP 3127 version of these functions, designed to be
8082 compatible with the hex() and oct() builtins from Python 3.0. They
8083 differ slightly in their output formats from the existing, unchanged
8084 Python 2.6 builtins. The expected usage of the future_builtins
8085 module is:
8086 from future_builtins import hex, oct
8087
Eric Smith7ef40bf2008-02-20 23:34:22 +00008088- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8089 exponents for exponents with absolute value < 100. Follows C99
8090 standard. This is a change on Windows, which would use 3 digits.
8091 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8092 so that any alterations it does to the resulting string will be
8093 available in stringlib/formatter.h (for float.__format__).
8094
Eric Smith5a3c1352008-02-19 13:21:56 +00008095- Implemented PEP 3101, Advanced String Formatting. This adds a new
8096 builtin format(); a format() method for str and unicode; a
8097 __format__() method to object, str, unicode, int, long, float, and
8098 datetime; the class string.Formatter; and the C API
8099 PyObject_Format().
8100
Georg Brandl3ee81df2008-05-17 18:14:43 +00008101- Fixed several potential crashes, all caused by specially crafted
8102 __del__ methods exploiting objects in temporarily inconsistent
8103 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008104
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008105- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008106 prevent a possible crash: an Abstract Base Class would try to access
8107 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008112- Clear all free lists during a gc.collect() of the highest generation
8113 in order to allow pymalloc to free more arenas. Python may give back
8114 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008115
Georg Brandl3ee81df2008-05-17 18:14:43 +00008116- Issue #2045: Fix an infinite recursion triggered when printing a
8117 subclass of collections.defaultdict, if its default_factory is set
8118 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008119
Christian Heimesf75dbef2008-02-08 00:11:31 +00008120- Fixed a minor memory leak in dictobject.c. The content of the free
8121 list was not freed on interpreter shutdown.
8122
Georg Brandl21e99f42010-03-07 15:23:59 +00008123- Limit free list of method and built-in function objects to 256

8127 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008128 to compact the internal free lists of pre-allocted ints and floats.
8129
Georg Brandl3ee81df2008-05-17 18:14:43 +00008130- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8131 calls. Python expected the return type int but the fork familie
8132 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008133
Georg Brandl3ee81df2008-05-17 18:14:43 +00008134- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008146- Patch #1473257: generator objects gain a gi_code attribute. This is
8147 the same object as the func_code attribute of the function that
8148 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008149
Georg Brandl3ee81df2008-05-17 18:14:43 +00008150- Issue #1920: "while 0" statements were completely removed by the
8151 compiler, even in the presence of an "else" clause, which is
8152 supposed to be run when the condition is false. Now the compiler
8153 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008154
Guido van Rossumeead05f2008-01-24 18:21:02 +00008155- A few crashers fixed: weakref_in_del.py (issue #1377858);
8156 loosing_dict_ref.py (issue #1303614, test67.py);
8157 borrowed_ref_[34].py (not in tracker).

8162
Georg Brandl3ee81df2008-05-17 18:14:43 +00008163- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008164 several extension methods and modules do not work without unicode
8165 support.
8166

8169
Georg Brandl14404b62008-01-19 19:27:05 +00008170- Issue #1679: "0x" was taken as a valid integer literal.
8171
Georg Brandl6caad7d2008-01-26 14:19:22 +00008172- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008173 added.
8174
Christian Heimesc94e2b52008-01-14 04:13:37 +00008175- sys.float_info / PyFloat_GetInfo: The floating point information
8176 object was converted from a dict to a specialized structseq object.
8177
Georg Brandl3ee81df2008-05-17 18:14:43 +00008178- Patch #1816: Added sys.flags structseq. It exposes the status of
8179 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008180
Georg Brandl3ee81df2008-05-17 18:14:43 +00008181- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandlaed6c662008-01-07 17:25:53 +00008191- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8192
Georg Brandl3ee81df2008-05-17 18:14:43 +00008193- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8194 envvar and sys.dont_write_bytecode attribute. All these can be set
8195 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008197- Improve some exception messages when Windows fails to load an
8198 extension module. Now we get for example '%1 is not a valid Win32
8199 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00008206- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008207 and INF. float("nan"), float("inf") and float("-inf") now work on
8208 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008210- Compiler now generates simpler and faster code for dictionary
8211 literals. The oparg for BUILD_MAP now indicates an estimated
8212 dictionary size. There is a new opcode, STORE_MAP, for adding
8213 entries to the dictionary.

8243 file can now be directly executed by passing their name to the
8244 interpreter. The directory/zipfile is automatically inserted as the
8245 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008247- Issue #1265: Fix a problem with sys.settrace, if the tracing
8248 function uses a generator expression when at the same time the
8249 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008250
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008251- sets and frozensets now have an isdisjoint() method.

8256
Georg Brandl21e99f42010-03-07 15:23:59 +00008257- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008258 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8259 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008260
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261- Issue #1686386: Tuple's tp_repr did not take into account the
8262 possibility of having a self-referential tuple, which is possible
8263 from C code. Nor did object's tp_str consider that a type's tp_str
8264 could do something that could lead to an inifinite recursion.
8265 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8266 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008267
Georg Brandl3ee81df2008-05-17 18:14:43 +00008268- Issue #1164: It was possible to trigger deadlock when using the
8269 'print' statement to write to a file since the GIL was not released
8270 as needed. Now PyObject_Print() does the right thing along with
8271 various tp_print implementations of the built-in types and those in
8272 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008273
Georg Brandl3ee81df2008-05-17 18:14:43 +00008274- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00008281- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008282 PyObject_Call() never calling back out to Python code to trigger
8283 recursion depth updates/checks. Required the creation of a static
8284 RuntimeError instance in case normalizing an exception put the
8285 recursion check value past its limit. Fixes crashers
8286 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008287

Neal Norwitz0ac60192007-05-27 04:08:54 +00008301- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008302 __*__ attributes. (Some already existed, e.g., __doc__ and
8303 __name__.)

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008305- Add -3 option to the interpreter to warn about features that are
8306 deprecated and will be changed/removed in Python 3.0.
8307
Georg Brandl2134e752007-05-21 20:34:16 +00008308- Patch #1686487: you can now pass any mapping after '**' in function
8309 calls.
8310
Collin Winter62903052007-05-18 23:11:24 +00008311- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008312 "except E as target:". This is to provide forwards compatibility
8313 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008320- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008321 setting a plain string, ie don't expand to single letter identifiers.
8322
Raymond Hettinger13936692007-04-11 18:40:58 +00008323- Request #1191699: Slices can now be pickled.
8324
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008325- Request #1193128: str.translate() now allows a None argument for
8326 translations that only remove characters without re-mapping the
8327 remaining characters.
8328
Georg Brandl5cb76c12007-03-21 09:00:39 +00008329- Patch #1682205: a TypeError while unpacking an iterable is no longer

8333
Guido van Rossum143b5642007-03-23 04:58:42 +00008334- Bug #1683368: The object.__init__() and object.__new__() methods are
8335 now stricter in rejecting excess arguments. The only time when
8336 either allows excess arguments is when it is not overridden and the
8337 other one is. For backwards compatibility, when both are
8338 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008339 warning later). Also, type.__init__() insists on the same signature
8340 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008341
Georg Brandl3ee81df2008-05-17 18:14:43 +00008342- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8343 object to complex using its __complex__() method before falling back
8344 to the __float__() method. Therefore, the functions in the cmath
8345 module now can operate on objects that define a __complex__()
8346 method.

8350 same slot names.

8363
Georg Brandl7b9c5552007-03-12 14:30:05 +00008364- Bug #1678647: write a newline after printing an exception in any
8365 case, even when converting the value to a string failed.
8366
Georg Brandl871f1bc2007-03-12 13:17:36 +00008367- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008368 its argument, if it exists. If not, it will work like before. This
8369 allows customizing the output of dir() in the presence of a
8370 __getattr__().

8379 parthensized forms. This means complex(repr(x)) now works instead of
8380 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008381
Georg Brandlaa2321b2007-03-07 00:40:28 +00008382- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008383 makes the filenames the warning module prints much more sensible
8384 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008397- Patch #1674228: when assigning a slice (old-style), check for the
8398 sq_ass_slice instead of the sq_slice slot.
8399
Georg Brandl3ee81df2008-05-17 18:14:43 +00008400- When printing an unraisable error, don't print exceptions. before
8401 the name. This duplicates the behavior whening normally printing
8402 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008934 AttributeError instead of an IOError when the server's response
8935 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008936

Georg Brandl3ee81df2008-05-17 18:14:43 +00008952- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl92a6bae2007-03-13 17:43:32 +00008968- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008969 are set for invalid interpolation sequences that would lead to
8970 errors on reading back those values.

9026 TestCase and TestSuite subclasses (not instances) are no longer
9027 accepted in TestSuite.addTest(). This should cause no
9028 incompatibility since it never made sense with ordinary subclasses
9029 -- the failure just occurred later, with a more cumbersome
9030 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009311 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009412- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009413 time so that opening a database previously created with the DB_DUP
9414 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9415 opens. Specifically: dictionary assignment to a DB object will
9416 replace all values for a given key when the database allows
9417 duplicate values. DB users should use DB.put(k, v) when they want
9418 to store duplicates; not DB[k] = v.

9779 of w# format code incorrectly truncated the length to an int, even
9780 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9781 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009811- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9812 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
