Ned Deily0d0ea482012-02-10 12:59:06 +0100866- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
867 Distutils-based packages with C extension modules may fail because
868 Apple has removed gcc-4.2, the version used to build python.org
869 64-bit/32-bit Pythons. If the user does not explicitly override
870 the default C compiler by setting the CC environment variable,
871 Distutils will now attempt to compile extension modules with clang
872 if gcc-4.2 is required but not found. Also as a convenience, if
873 the user does explicitly set CC, substitute its value as the default
874 compiler in the Distutils LDSHARED configuration variable for OS X.
875 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
876 SDK, neither of which are available in Xcode 4. This change does not
877 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001150- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1151 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1152 interpreter process. This could cause failures in non-Distutils subprocesses
1153 and was unreliable since tests or user programs could modify the interpreter
1154 environment after Distutils set it. Instead, have Distutils set the the
1155 deployment target only in the environment of each build subprocess. It is
1156 still possible to globally override the default by setting
1157 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1158 greater or equal to the default value, the value with which the interpreter
1159 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04001187- sys.setcheckinterval() now updates the current ticker count as well as
1188 updating the check interval, so if the user decreases the check interval,
1189 the ticker doesn't have to wind down to zero from the old starting point
1190 before the new interval takes effect. And if the user increases the
1191 interval, it makes sure the new limit takes effect right away rather have an
1192 early task switch before recognizing the new interval.

2133 by Andrew Bennetts.

2142
Raymond Hettinger20397532010-09-12 02:11:45 +00002143- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2144 This prevents user-created self-referencing ordered dictionaries from
2145 becoming permanently uncollectable GC garbage. The downside is that
2146 removing __del__ means that the internal doubly-linked list has to wait for
2147 GC collection rather than freeing memory immediately when the refcnt drops
2148 to zero.
2149
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002150- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

2153
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002154- Issue #9792: In case of connection failure, socket.create_connection()
2155 would swallow the exception and raise a new one, making it impossible
2156 to fetch the original errno, or to filter timeout errors. Now the
2157 original error is re-raised.
2158
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002159- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2160 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2161 be updated back after the system call. Original patch by Brian Brazil.

2168
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002169- Issue #808164: Fixed socket.close to avoid references to globals, to
2170 avoid issues when socket.close is called from a __del__ method.
2171

2173 can be set to False to turn off the previously undocumented 'popularity'
2174 heuristic. Patch by Terry Reedy and Eli Bendersky
2175
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00002176- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
2177 falling into recursion.
2178
R. David Murray7c4bf552010-08-25 01:45:57 +00002179- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2180 character years even if the message contains RFC822 two character years.
2181
Daniel Stutzbach91287322010-08-24 21:09:30 +00002182- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00002193- Issue #9214: Set operations on KeysView or ItemsView in the collections
2194 module now correctly return a set. (Patch by Eli Bendersky.)
2195
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002196- Issue #9617: Signals received during a low-level write operation aren't
2197 ignored by the buffered IO layer anymore.
2198
Benjamin Peterson52c36052010-08-21 03:03:22 +00002199- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2200 are not held onto after they are deleted elsewhere.
2201
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002202- Issue #9626: the view methods for collections.OrderedDict() were returning
2203 the unordered versions inherited from dict. Those methods are now
2204 overridden to provide ordered views.
2205
Éric Araujo0389ae62010-08-14 03:07:46 +00002206- Issue #8688: MANIFEST files created by distutils now include a magic
2207 comment indicating they are generated. Manually maintained MANIFESTs
2208 without this marker will not be overwritten or removed.
2209
Antoine Pitroue1436d12010-08-12 15:25:51 +00002210- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2211 and a BadZipfile error is raised if it doesn't match (as used to be the
2212 case in Python 2.5 and earlier).
2213
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002214- Issue #9550: a BufferedReader could issue an additional read when the
2215 original read request had been satisfied, which could block indefinitely
2216 when the underlying raw IO channel was e.g. a socket. Report and original
2217 patch by Jason V. Miller.
2218
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002219- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00002237- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2238 This is how it is supposed to work, wget and curl do the same. Previous
2239 behavior was wrong.

2247 the option character for the added 'h/help' option if prefix_chars
2248 does not contain a '-', instead of raising an error.
2249

2623 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00002867- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
2868 the method could block indefinitely if called just before the event loop
2869 started running. This also fixes the occasional freezes witnessed in
2870 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +00002872- Issue #5103: SSL handshake would ignore the socket timeout and block
2873 indefinitely if the other end didn't respond.
2874
Georg Brandlfee0f442010-05-22 21:26:21 +00002875- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002968 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

2994
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002995- Issue #8329: Don't return the same lists from select.select when no fds are
2996 changed.
2997
Georg Brandlfee0f442010-05-22 21:26:21 +00002998- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002999 on 64-bit machines. The shift count for either left or right shift is
3000 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00003008- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3009 with a non-empty format string. This is an effort to future-proof user
3010 code. If a derived class does not currently implement __format__ but later
3011 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003012 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003013 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003063- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3064 InvalidOperation instead of returning False. (Comparisons involving a quiet
3065 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3066 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00003068- Issue #2531: Comparison operations between floats and Decimal instances now
3069 return a result based on the numeric values of the operands; previously they

3071 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00003085- Comparisons using one of <, <=, >, >= between a complex instance and a
3086 Fractions instance now raise TypeError instead of returning True/False. This
3087 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3088 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003499 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003505- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003506 file position when calling `truncate()`. It would previously change the file
3507 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003508 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3509

3511 class used to represent files stored inside an archive. The new
3512 implementation is significantly faster and can be wrapped in a
3513 ``io.BufferedReader`` object for more speedups. It also solves an issue
3514 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3603-----------------
3604
Georg Brandlba83f822010-03-14 09:50:54 +00003605- The ``__complex__()`` method is now looked up on the class of instances to
3606 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003607
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003608- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3609 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3610
Mark Dickinson1b34d252010-01-01 17:27:30 +00003611- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003612 DeprecationWarning when passed a float argument where an integer was expected.
3613 These functions and methods now raise TypeError instead. The majority of the
3614 effects of this change are in the extension modules, but some core functions
3615 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3616 and many unicode/str methods.

3627 used to drop the time part of the result.
3628
Georg Brandlba83f822010-03-14 09:50:54 +00003629- Issue #1811: Improve accuracy and cross-platform consistency for true division
3630 of integers: the result of a/b is now correctly rounded for ints a and b (at
3631 least on IEEE 754 platforms), and in particular does not depend on the
3632 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003633
Georg Brandlba83f822010-03-14 09:50:54 +00003634- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
3635 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
3636 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00003639 executables on OSX.
3640
Georg Brandlba83f822010-03-14 09:50:54 +00003641 These executables now work properly with the arch(1) command: ``arch -ppc
3642 python`` will start a universal binary version of python in PPC mode (unlike
3643 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00003666 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00003814 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3815 providing correctly-rounded strtod and dtoa C functions. This code is
3816 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3817 the C compiler. There may be a small number of platforms on which correct
3818 operation of this code cannot be guaranteed, so the code is not used: notably,
3819 this applies to platforms where the C double format is not IEEE 754 binary64,
3820 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3821 and Python's configure script is unable to determine how to change the FPU
3822 precision. On these platforms conversions use the platform strtod and dtoa,
3823 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003825- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3826 uses the correctly-rounded string <-> float conversions described above (when
3827 available), and so produces correctly rounded results that will display nicely
3828 under the float repr. There are two related small changes: (1) round now
3829 accepts any class with an ``__index__()`` method for its second argument (but
3830 no longer accepts floats for the second argument), and (2) an excessively
3831 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3832 raises an exception.

4211 this code path is really executed because I cannot move to such directory on

4238 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00005409 - Packing a float now always gives a Deprecation Warning. Previously it
5410 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00005412 - If x is not an int, long or float, then packing x will always result in
5413 struct.error. Previously an x with an __int__ method could be packed by
5414 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5415 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5416 neither __int__ nor __long__, TypeError used to be raised (with a
5417 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5418 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00005420 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
5421 argument with an __int__ method can be packed, but use of this feature
5422 triggers a DeprecationWarning.

5614
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005615- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5616 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5617 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5618 ``printf`` function, whereas PyString_FromFormat has an independent
5619 implementation and uses "%zd" on all platforms for size_t values.
5620 This makes a difference on win64, where ``printf`` needs "%Id" to display
5621 64bit values.

5627 object; previously an int would be returned for small values. the __long__
5628 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00005640- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005641 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5642 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5643 when given a tuple of classes as second argument, were looking up
5644 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5645 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005784What's New in Python 2.6 beta 3?
5785================================
5786
Barry Warsaw07a4a382008-08-21 01:15:08 +00005787*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005788
5789Core and Builtins
5790-----------------
5791
Guido van Rossumf8402962008-08-20 15:01:50 +00005792- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5793 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5794 extensions do not automatically benefit from the class attribute
5795 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5796 to their tp_flags field if they care. This is a backwards
5797 compatibility feature; in 3.0, all types will use the cache by
5798 default.
5799
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005800- Keyword arguments can now follow starred arguments. (``f(a, *args,
5801 keyword=23)`` is now valid syntax.)
5802
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005803- ctypes function pointers that are COM methods have a boolean True
5804 value again.
5805
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005806- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5807 by denying s# to parse objects that have a releasebuffer procedure,
5808 and introducing s*.
5809
Georg Brandl1e13ea92008-08-11 09:07:59 +00005810- Issue #3537: Fix an assertion failure when an empty but presized dict
5811 object was stored in the freelist.
5812
Mark Dickinsonb6467572008-08-04 21:30:09 +00005813- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5814 ValueError consistently across platforms.
5815
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005816- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5817 (64bit Unix, for example), unichr() would truncate its argument and return
5818 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5819
Neal Norwitze7d8be82008-07-31 17:17:14 +00005820- Apply security patches from Apple.
5821
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005822- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5823 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5824
Antoine Pitrou92f82162008-07-25 22:22:08 +00005825- Issue #1819: function calls with several named parameters are now on
5826 average 35% faster (as measured by pybench).
5827
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005828- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5829 the python debugger steps into a class statement: the free variables (local
5830 variables defined in an outer scope) would be deleted from the outer scope.
5831
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005832- Issue #2620: Overflow checking when allocating or reallocating memory
5833 was not always being done properly in some python types and extension
5834 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5835 all been updated to perform better checks and places in the code that
5836 would previously leak memory on the error path when such an allocation
5837 failed have been fixed.
5838

5840-------
5841
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005842- Issue #3612: Added some missing basic types in ctypes.wintypes.
5843
Benjamin Petersone977ad42008-08-20 01:42:01 +00005844- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5845 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5846
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005847- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5848 version reported by these tools does not necessarily follow the python
5849 version numbering scheme, so the module is less strict when parsing it.
5850
Nick Coghlanf70385a2008-08-18 12:42:46 +00005851- Issue #2235: Added Py3k warnings for types which will become unhashable
5852 under the stricter __hash__ inheritance rules in 3.0. Several types
5853 which did not meet the rules for hash invariants and were already
5854 unhashable in 3.0 have now been explicitly flagged as unhashable in
5855 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5856 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5857
Brett Cannon88f801d2008-08-18 00:46:22 +00005858- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5859 imported into the module but exposed as part of the module's API.
5860
Brett Cannon7b96f072008-08-18 00:41:11 +00005861- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5862
Brett Cannon46225e72008-08-18 00:36:52 +00005863- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005865- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5866
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005867- Issue #3575: Incremental decoder's decode function now takes bytearray
5868 by using 's*' instead of 't#'.
5869
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005870- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005871 fails unicode conversion on 2nd parameter. (windows only)
5872
Georg Brandl222e2082010-08-01 22:27:39 +00005873- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005874 in a redirect.
5875
Brett Cannonabe423e2008-08-16 21:47:07 +00005876- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005877 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005878
Facundo Batistaeb90b782008-08-16 14:44:07 +00005879- Issue #2776: fixed small issue when handling an URL with double slash
5880 after a 302 response in the case of not going through a proxy.
5881
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005882- Issue #2676: in the email package, content-type parsing was hanging on
5883 pathological input because of quadratic or exponential behaviour of a
5884 regular expression.
5885
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005886- Issue #3476: binary buffered reading through the new "io" library is now
5887 thread-safe.
5888
Brett Cannonbf3157b2008-08-14 05:00:03 +00005889- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5890 since mimetools itself is deprecated. Because modules are cached, all
5891 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5892
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005893- Issue #3134: shutil referenced undefined WindowsError symbol.
5894
Robert Schuppenies14646332008-08-10 11:01:53 +00005895- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5896 menu entries were not deleted.
5897
Brett Cannon83e81842008-08-09 23:30:55 +00005898- Copied the implementation of reduce() to _functools.reduce() to have a
5899 version that did not raise a DeprecationWarning under -3.
5900
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005901- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5902 a MemoryError rather than silently stop the iteration.
5903
Guido van Rossum59ce9012008-08-09 14:55:34 +00005904- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5905 to _sre.compile() will now be rejected. This should not affect anybody
5906 since the re.compile() function never generates invalid re-bytecode.
5907
Skip Montanaroa032bf42008-08-08 22:52:51 +00005908- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5909 upon first access it can be automatically initialized from the csv file if
5910 it wasn't initialized during instantiation.
5911
Brett Cannon3aa2a492008-08-06 22:28:09 +00005912- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5913 the reload() built-in has been removed.
5914
Brett Cannon7e30b672008-08-04 21:52:25 +00005915- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005916 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005927 asking for a specific length. This problem only affected files opened
5928 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005929

5956
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005957- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005978What's New in Python 2.6 beta 2?
5979================================
5980
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005981*Release date: 17-Jul-2008*
5982
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005983Core and Builtins
5984-----------------
5985
Georg Brandl3e483f62008-07-16 22:57:41 +00005986- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5987 its methods now allow for items objects that can be converted to
5988 an integer using operator.index().
5989
Mark Dickinson64b7e502008-07-16 09:40:03 +00005990- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5991 produced a ValueError instead of giving the correct float.
5992
Eric Smitha5fa5a22008-07-16 00:11:49 +00005993- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5994 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5995
Mark Dickinson7103aa42008-07-15 19:08:33 +00005996- Issue #3008: the float type has a new instance method 'float.hex'
5997 and a new class method 'float.fromhex' to convert floating-point
5998 numbers to and from hexadecimal strings, respectively.
5999
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006000- Issue #2235: __hash__ is once again inherited by default. To allow
6001 collections.Hashable to remain meaningful in the presence of the
6002 default hash implementation (object.__hash__), it is now possible
6003 to explicit block inheritance of hash by setting __hash__=None at
6004 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6005 level.
6006
Nick Coghlanb028f502008-07-13 14:52:36 +00006007- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6008 the parent module cannot be found while performing an absolute import.
6009 This means that an incorrectly defined __package__ attribute will
6010 now only prevent relative imports in that module rather than causing
6011 all imports from that module to fail.
6012
Nick Coghlan14ff9942008-07-08 14:21:42 +00006013- Issue #2517: Allow unicode messages in Exceptions again by correctly
6014 bypassing the instance dictionary when looking up __unicode__ on
6015 new-style classes.
6016
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006017- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6018 set to a custom object whose write() method happens to install
6019 another file in sys.stdout.
6020
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006021- Issue #3088: Corrected a race condition in classes derived from
6022 threading.local: the first member set by a thread could be saved in
6023 another thread's dictionary.
6024
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006025- Issue #3004: Minor change to slice.indices(): the start and stop
6026 arguments are now treated identically, making the behaviour easier
6027 to describe and understand. For example, slice(None, -10,
6028 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6029 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6030 10, -1).
6031
Georg Brandl278fc502008-07-19 12:46:12 +00006032- Issue #3219: Calling a function with repeated keyword arguments,
6033 f(a=2, a=23), would not cause a syntax error. This was a regression
6034 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006035
Georg Brandl278fc502008-07-19 12:46:12 +00006036- Issue #2862: Make int and float freelist management consistent with
6037 other freelists. Changes their CompactFreeList apis into
6038 ClearFreeList apis and calls them via gc.collect().

6042
Thomas Heller57adf222008-08-14 19:10:48 +00006043- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6044 api functions without holding the GIL, which could lead to a fatal
6045 error when they failed.
6046
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006047- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6056 ForkingPickler.register() to resolve conflict with ctypes.
6057
Vinay Sajip51e65192008-07-18 09:01:10 +00006058- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006059
Thomas Heller880f5292008-07-15 19:39:38 +00006060- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6061 a valid dlerror() message.

6069
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006070- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006071
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006072- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6073 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006074 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006075 content-length. The problem had been corrected in the 2.4 branch, but never
6076 merged into trunk.
6077
Georg Brandle78fbcc2008-07-05 10:13:36 +00006078- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006091- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6092 handling is now the same as that of other special attributes like __name__).
6093
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006094- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6550 and ``formatwarning()`` gain an optional 'line' argument which is
6551 not called by default for backwards-compatibility reasons. Setting
6552 ``warnings.showwarning()`` to an implementation that lacks support
6553 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006616- Issue #2550: The approach used by client/server code for obtaining
6617 ports to listen on in network-oriented tests has been refined in an
6618 effort to facilitate running multiple instances of the entire
6619 regression test suite in parallel without issue.
6620 test_support.bind_port() has been fixed such that it will always
6621 return a unique port -- which wasn't always the case with the
6622 previous implementation, especially if socket options had been set
6623 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6624 new implementation of bind_port() will actually raise an exception
6625 if it is passed an AF_INET/SOCK_STREAM socket with either the
6626 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6627 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6628 the socket it's been passed. This currently only applies to
6629 Windows. This option prevents any other sockets from binding to the
6630 host/port we've bound to, thus removing the possibility of the
6631 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6632 when a second SOCK_STREAM socket binds and accepts to a host/port
6633 that's already been bound by another socket. The optional preferred
6634 port parameter to bind_port() has been removed. Under no
6635 circumstances should tests be hard coding ports!
6636
6637 test_support.find_unused_port() has also been introduced, which will
6638 pass a temporary socket object to bind_port() in order to obtain an
6639 unused port. The temporary socket object is then closed and
6640 deleted, and the port is returned. This method should only be used
6641 for obtaining an unused port in order to pass to an external program
6642 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6643 a parameter to a server-oriented class that doesn't give you direct
6644 access to the underlying socket used.
6645
6646 Finally, test_support.HOST has been introduced, which should be used
6647 for the host argument of any relevant socket calls (i.e. bind and
6648 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006649
6650 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006651 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006652 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6653 test_asynchat and test_socket_ssl.
6654
Georg Brandl3ee81df2008-05-17 18:14:43 +00006655 It is now possible for multiple instances of the regression test
6656 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006935- Added the future_builtins module, which contains hex() and oct().
6936 These are the PEP 3127 version of these functions, designed to be
6937 compatible with the hex() and oct() builtins from Python 3.0. They
6938 differ slightly in their output formats from the existing, unchanged
6939 Python 2.6 builtins. The expected usage of the future_builtins
6940 module is:
6941 from future_builtins import hex, oct
6942
Eric Smith7ef40bf2008-02-20 23:34:22 +00006943- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6944 exponents for exponents with absolute value < 100. Follows C99
6945 standard. This is a change on Windows, which would use 3 digits.
6946 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6947 so that any alterations it does to the resulting string will be
6948 available in stringlib/formatter.h (for float.__format__).
6949
Eric Smith5a3c1352008-02-19 13:21:56 +00006950- Implemented PEP 3101, Advanced String Formatting. This adds a new
6951 builtin format(); a format() method for str and unicode; a
6952 __format__() method to object, str, unicode, int, long, float, and
6953 datetime; the class string.Formatter; and the C API
6954 PyObject_Format().
6955
Georg Brandl3ee81df2008-05-17 18:14:43 +00006956- Fixed several potential crashes, all caused by specially crafted
6957 __del__ methods exploiting objects in temporarily inconsistent
6958 state.

6969 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006970
Georg Brandl3ee81df2008-05-17 18:14:43 +00006971- Issue #2045: Fix an infinite recursion triggered when printing a
6972 subclass of collections.defaultdict, if its default_factory is set
6973 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006974

6984
Georg Brandl3ee81df2008-05-17 18:14:43 +00006985- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

6987 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007001- Patch #1473257: generator objects gain a gi_code attribute. This is
7002 the same object as the func_code attribute of the function that
7003 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007004
Georg Brandl3ee81df2008-05-17 18:14:43 +00007005- Issue #1920: "while 0" statements were completely removed by the
7006 compiler, even in the presence of an "else" clause, which is
7007 supposed to be run when the condition is false. Now the compiler
7008 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007009

Georg Brandl3ee81df2008-05-17 18:14:43 +00007033- Patch #1816: Added sys.flags structseq. It exposes the status of
7034 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007035
Georg Brandl3ee81df2008-05-17 18:14:43 +00007036- Objects/structseq.c: Implemented new structseq representation. The
7037 patch makes structseqs (e.g. the return value of os.stat) more
7038 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007039
Georg Brandl3ee81df2008-05-17 18:14:43 +00007040- Patch #1700288: added a type attribute cache that caches method
7041 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007042
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007043- Bug #1776: __import__() no longer accepts filenames on any platform.
7044 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007045
Georg Brandlaed6c662008-01-07 17:25:53 +00007046- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7047
Georg Brandl3ee81df2008-05-17 18:14:43 +00007048- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7049 envvar and sys.dont_write_bytecode attribute. All these can be set
7050 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007051
Georg Brandl3ee81df2008-05-17 18:14:43 +00007052- Improve some exception messages when Windows fails to load an
7053 extension module. Now we get for example '%1 is not a valid Win32
7054 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007055
Georg Brandl3ee81df2008-05-17 18:14:43 +00007056- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007058- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7059 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007060
Christian Heimes0a8143f2007-12-18 23:22:54 +00007061- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007062 and INF. float("nan"), float("inf") and float("-inf") now work on
7063 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007064
Georg Brandl3ee81df2008-05-17 18:14:43 +00007065- Compiler now generates simpler and faster code for dictionary
7066 literals. The oparg for BUILD_MAP now indicates an estimated
7067 dictionary size. There is a new opcode, STORE_MAP, for adding
7068 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007069
Georg Brandl3ee81df2008-05-17 18:14:43 +00007070- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007072- Issue #1620: New property decorator syntax was modifying the
7073 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00007074
Georg Brandl3ee81df2008-05-17 18:14:43 +00007075- Issue #1538: Avoid copying string in split/rsplit if the split char
7076 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007077
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007078- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007079 SystemError.
7080
Nick Coghlanef01d822007-12-03 12:55:17 +00007081- PEP 366: Allow explicit relative imports when executing modules
7082 inside packages with the -m switch via a new module level
7083 __package__ attribute.
7084

7086 running, and if the deallocation of its frames somehow calls the
7087 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007088

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007092 attribute of an empty cell object.
7093
Georg Brandl3ee81df2008-05-17 18:14:43 +00007094- Issue #1460: The utf-7 incremental decoder did not accept truncated
7095 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007096
Georg Brandl3ee81df2008-05-17 18:14:43 +00007097- Patch #1739468: Directories and zipfiles containing a __main__.py
7098 file can now be directly executed by passing their name to the
7099 interpreter. The directory/zipfile is automatically inserted as the
7100 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007101
Georg Brandl3ee81df2008-05-17 18:14:43 +00007102- Issue #1265: Fix a problem with sys.settrace, if the tracing
7103 function uses a generator expression when at the same time the
7104 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007105
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007106- sets and frozensets now have an isdisjoint() method.
7107
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007108- optimize the performance of builtin.sum().
7109
Neal Norwitz44f326e2007-10-05 05:29:17 +00007110- Fix warnings found by the new version of the Coverity checker.
7111
Georg Brandl21e99f42010-03-07 15:23:59 +00007112- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007113 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7114 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007115
Georg Brandl3ee81df2008-05-17 18:14:43 +00007116- Issue #1686386: Tuple's tp_repr did not take into account the
7117 possibility of having a self-referential tuple, which is possible
7118 from C code. Nor did object's tp_str consider that a type's tp_str
7119 could do something that could lead to an inifinite recursion.
7120 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7121 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007122
Georg Brandl3ee81df2008-05-17 18:14:43 +00007123- Issue #1164: It was possible to trigger deadlock when using the
7124 'print' statement to write to a file since the GIL was not released
7125 as needed. Now PyObject_Print() does the right thing along with
7126 various tp_print implementations of the built-in types and those in
7127 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007128
Georg Brandl3ee81df2008-05-17 18:14:43 +00007129- Issue #1147: Exceptions were directly allowing string exceptions in
7130 their throw() method even though string exceptions no longer
7131 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007132
Georg Brandl3ee81df2008-05-17 18:14:43 +00007133- Issue #1096: Prevent a segfault from getting the repr of a very
7134 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007135
Brett Cannon1e534b52007-09-07 04:18:30 +00007136- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007137 PyObject_Call() never calling back out to Python code to trigger
7138 recursion depth updates/checks. Required the creation of a static
7139 RuntimeError instance in case normalizing an exception put the
7140 recursion check value past its limit. Fixes crashers
7141 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007142
Georg Brandl3ee81df2008-05-17 18:14:43 +00007143- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007156- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007157 __*__ attributes. (Some already existed, e.g., __doc__ and
7158 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007159
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007160- Add -3 option to the interpreter to warn about features that are
7161 deprecated and will be changed/removed in Python 3.0.
7162
Georg Brandl2134e752007-05-21 20:34:16 +00007163- Patch #1686487: you can now pass any mapping after '**' in function
7164 calls.
7165
Collin Winter62903052007-05-18 23:11:24 +00007166- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007167 "except E as target:". This is to provide forwards compatibility
7168 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007169
Brett Cannon229cee22007-05-05 01:34:02 +00007170- Deprecate BaseException.message as per PEP 352.
7171
Georg Brandl3ee81df2008-05-17 18:14:43 +00007172- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007173 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007174
Vinay Sajip8549ce32007-05-06 17:53:37 +00007175- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007176 setting a plain string, ie don't expand to single letter identifiers.
7177
Raymond Hettinger13936692007-04-11 18:40:58 +00007178- Request #1191699: Slices can now be pickled.
7179
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007180- Request #1193128: str.translate() now allows a None argument for
7181 translations that only remove characters without re-mapping the
7182 remaining characters.
7183
Georg Brandl5cb76c12007-03-21 09:00:39 +00007184- Patch #1682205: a TypeError while unpacking an iterable is no longer
7185 masked by a generic one with the message "unpack non-sequence".
7186
Neal Norwitzaa754b72007-03-21 06:39:48 +00007187- Remove unused file Python/fmod.c.
7188
Guido van Rossum143b5642007-03-23 04:58:42 +00007189- Bug #1683368: The object.__init__() and object.__new__() methods are
7190 now stricter in rejecting excess arguments. The only time when
7191 either allows excess arguments is when it is not overridden and the
7192 other one is. For backwards compatibility, when both are
7193 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007194 warning later). Also, type.__init__() insists on the same signature
7195 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007196
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7198 object to complex using its __complex__() method before falling back
7199 to the __float__() method. Therefore, the functions in the cmath
7200 module now can operate on objects that define a __complex__()
7201 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007202
Georg Brandl3ee81df2008-05-17 18:14:43 +00007203- Patch #1623563: allow __class__ assignment for classes with
7204 __slots__. The old and the new class are still required to have the
7205 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007206
Georg Brandl3ee81df2008-05-17 18:14:43 +00007207- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Patch #1462488: Python no longer segfaults when
7211 ``object.__reduce_ex__()`` is called with an object that is faking
7212 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007213
Georg Brandl3ee81df2008-05-17 18:14:43 +00007214- Patch #1680015: Don't modify __slots__ tuple if it contains an

7218
Georg Brandl7b9c5552007-03-12 14:30:05 +00007219- Bug #1678647: write a newline after printing an exception in any
7220 case, even when converting the value to a string failed.
7221
Georg Brandl871f1bc2007-03-12 13:17:36 +00007222- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007223 its argument, if it exists. If not, it will work like before. This
7224 allows customizing the output of dir() in the presence of a
7225 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007226
Collin Winter276887b2007-03-12 16:11:39 +00007227- Patch #922167: Python no longer segfaults when faced with infinitely
7228 self-recursive reload() calls (as reported by bug #742342).
7229
Georg Brandl3ee81df2008-05-17 18:14:43 +00007230- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00007233- Patch #1491866: change the complex() constructor to allow
7234 parthensized forms. This means complex(repr(x)) now works instead of
7235 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007236
Georg Brandlaa2321b2007-03-07 00:40:28 +00007237- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007238 makes the filenames the warning module prints much more sensible
7239 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007240
Georg Brandl49aafc92007-03-07 00:34:46 +00007241- Variant of patch #697613: don't exit the interpreter on a SystemExit
7242 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007243 variable is given, but break into the interactive interpreter just
7244 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00007251
Georg Brandl0fca97a2007-03-05 22:28:08 +00007252- Patch #1674228: when assigning a slice (old-style), check for the
7253 sq_ass_slice instead of the sq_slice slot.
7254
Georg Brandl3ee81df2008-05-17 18:14:43 +00007255- When printing an unraisable error, don't print exceptions. before
7256 the name. This duplicates the behavior whening normally printing
7257 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00007258
Georg Brandl3ee81df2008-05-17 18:14:43 +00007259- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007759- Added a timeout parameter to the constructor of other protocols
7760 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7761 work started with create_connection() and timeout in httplib, and
7762 closes patch #723312.
7763
Vinay Sajip8549ce32007-05-06 17:53:37 +00007764- Patch #1676823: Added create_connection() to socket.py, which may be
7765 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007766 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007767

7780 GNOME or KDE browser, depending on whether there is a session of one

7788
Georg Brandlf66b6032007-03-14 08:27:52 +00007789- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007790 AttributeError instead of an IOError when the server's response
7791 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007792
Georg Brandl3ee81df2008-05-17 18:14:43 +00007793- Patch #957650: "%var%" environment variable references are now
7794 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00007796
Georg Brandl3ee81df2008-05-17 18:14:43 +00007797- Patch #1429539: pdb now correctly initializes the __main__ module
7798 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007799 correctly now.
7800
Georg Brandlbad6f192007-03-13 21:32:56 +00007801- The nonobvious commands.getstatus() function is now deprecated.

7807
Georg Brandl3ee81df2008-05-17 18:14:43 +00007808- Patch #1530482: add pydoc.render_doc() which returns the
7809 documentation for a thing instead of paging it to stdout, which
7810 pydoc.doc() does.

7818 parameter which can be set to False to prevent the default
7819 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007820
Georg Brandl9e6b4702007-03-13 18:15:41 +00007821- Patch #1581073: add a flag to textwrap that prevents the dropping of
7822 whitespace while wrapping.
7823
Georg Brandl92a6bae2007-03-13 17:43:32 +00007824- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007825 are set for invalid interpolation sequences that would lead to
7826 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007827

Georg Brandl94fe3f52007-03-13 09:32:11 +00007841- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00007842 field names in its exception message if you try to write a record
7843 with a dictionary containing fields not in the CSV field names list.

7869 returned string up to the first NUL character.

7880
Georg Brandl3ee81df2008-05-17 18:14:43 +00007881- unittest now verifies more of its assumptions. In particular,
7882 TestCase and TestSuite subclasses (not instances) are no longer
7883 accepted in TestSuite.addTest(). This should cause no
7884 incompatibility since it never made sense with ordinary subclasses
7885 -- the failure just occurred later, with a more cumbersome
7886 exception.

7895 given a unicode argument and os.listdir() returns unicode filenames.
7896
Georg Brandl3ee81df2008-05-17 18:14:43 +00007897- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00008275 time so that opening a database previously created with the DB_DUP
8276 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8277 opens. Specifically: dictionary assignment to a DB object will
8278 replace all values for a given key when the database allows
8279 duplicate values. DB users should use DB.put(k, v) when they want
8280 to store duplicates; not DB[k] = v.

8287 characters with ASCII value less than 32. Also, it correctly quotes
8288 dots only if they occur on a single line, as opposed to the previous
8289 behavior of quoting dots if they are the second character of any
8290 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008291

Georg Brandl3ee81df2008-05-17 18:14:43 +00008668- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8669 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
