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

Ned Deily87e82bb2011-06-28 19:52:59 -07001153- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1154 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1155 interpreter process. This could cause failures in non-Distutils subprocesses
1156 and was unreliable since tests or user programs could modify the interpreter
1157 environment after Distutils set it. Instead, have Distutils set the the
1158 deployment target only in the environment of each build subprocess. It is
1159 still possible to globally override the default by setting
1160 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1161 greater or equal to the default value, the value with which the interpreter
1162 was built.

2130 handles non-blocking readinto() returning None correctly.

2133 SSLSocket.sendto() to match the corresponding socket methods. Also,
2134 fix various SSLSocket methods to raise socket.error rather than an

2136 by Andrew Bennetts.

2145
Raymond Hettinger20397532010-09-12 02:11:45 +00002146- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2147 This prevents user-created self-referencing ordered dictionaries from
2148 becoming permanently uncollectable GC garbage. The downside is that
2149 removing __del__ means that the internal doubly-linked list has to wait for
2150 GC collection rather than freeing memory immediately when the refcnt drops
2151 to zero.
2152
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002153- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00002154 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002155 value.
2156
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002157- Issue #9792: In case of connection failure, socket.create_connection()
2158 would swallow the exception and raise a new one, making it impossible
2159 to fetch the original errno, or to filter timeout errors. Now the
2160 original error is re-raised.
2161
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002162- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2163 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2164 be updated back after the system call. Original patch by Brian Brazil.
2165

2170 ConfigParser.write.
2171
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002172- Issue #808164: Fixed socket.close to avoid references to globals, to
2173 avoid issues when socket.close is called from a __del__ method.
2174
Terry Reedyd2d2ae92010-11-11 23:22:19 +00002175- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
2176 can be set to False to turn off the previously undocumented 'popularity'
2177 heuristic. Patch by Terry Reedy and Eli Bendersky
2178
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00002179- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
2180 falling into recursion.
2181
R. David Murray7c4bf552010-08-25 01:45:57 +00002182- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2183 character years even if the message contains RFC822 two character years.
2184
Daniel Stutzbach91287322010-08-24 21:09:30 +00002185- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00002196- Issue #9214: Set operations on KeysView or ItemsView in the collections
2197 module now correctly return a set. (Patch by Eli Bendersky.)
2198
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002199- Issue #9617: Signals received during a low-level write operation aren't
2200 ignored by the buffered IO layer anymore.
2201
Benjamin Peterson52c36052010-08-21 03:03:22 +00002202- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2203 are not held onto after they are deleted elsewhere.
2204
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002205- Issue #9626: the view methods for collections.OrderedDict() were returning
2206 the unordered versions inherited from dict. Those methods are now
2207 overridden to provide ordered views.
2208
Éric Araujo0389ae62010-08-14 03:07:46 +00002209- Issue #8688: MANIFEST files created by distutils now include a magic
2210 comment indicating they are generated. Manually maintained MANIFESTs
2211 without this marker will not be overwritten or removed.
2212
Antoine Pitroue1436d12010-08-12 15:25:51 +00002213- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2214 and a BadZipfile error is raised if it doesn't match (as used to be the
2215 case in Python 2.5 and earlier).
2216
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002217- Issue #9550: a BufferedReader could issue an additional read when the
2218 original read request had been satisfied, which could block indefinitely
2219 when the underlying raw IO channel was e.g. a socket. Report and original
2220 patch by Jason V. Miller.
2221
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002222- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00002240- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2241 This is how it is supposed to work, wget and curl do the same. Previous
2242 behavior was wrong.
2243

2247 encoded word encoded in base64 is lacking padding.
2248
R. David Murray1cbf78e2010-08-03 18:14:01 +00002249- Issue #9444: Argparse now uses the first element of prefix_chars as
2250 the option character for the added 'h/help' option if prefix_chars
2251 does not contain a '-', instead of raising an error.
2252
Georg Brandl7f0c3ff2010-08-01 21:18:52 +00002253- Issue #9354: Provide getsockopt() in asyncore's file_wrapper.

2625 objects. (1) The comparison could incorrectly return True in some cases
2626 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2627 (2) The comparison raised an OverflowError for large integers, leading
2628 to unpredictable exceptions when combining integers and complex objects

Georg Brandlfee0f442010-05-22 21:26:21 +00002870- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
2871 the method could block indefinitely if called just before the event loop
2872 started running. This also fixes the occasional freezes witnessed in
2873 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +00002875- Issue #5103: SSL handshake would ignore the socket timeout and block
2876 indefinitely if the other end didn't respond.
2877
Georg Brandlfee0f442010-05-22 21:26:21 +00002878- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Georg Brandlfee0f442010-05-22 21:26:21 +00002889- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
2890 string "python" as the *ident*. openlog() arguments are all optional and
2891 keywords.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002971 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

2999 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00003011- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3012 with a non-empty format string. This is an effort to future-proof user
3013 code. If a derived class does not currently implement __format__ but later
3014 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003015 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003016 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003066- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3067 InvalidOperation instead of returning False. (Comparisons involving a quiet
3068 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3069 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00003071- Issue #2531: Comparison operations between floats and Decimal instances now
3072 return a result based on the numeric values of the operands; previously they
3073 returned an arbitrary result based on the relative ordering of id(float) and
3074 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00003088- Comparisons using one of <, <=, >, >= between a complex instance and a
3089 Fractions instance now raise TypeError instead of returning True/False. This
3090 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3091 <=> complex, and complex <=> complex comparisons.

3454 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3455 returning NULL. The macro now returns a statically allocated empty string

Georg Brandlba83f822010-03-14 09:50:54 +00003502 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003508- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003509 file position when calling `truncate()`. It would previously change the file
3510 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003511 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3512

3514 class used to represent files stored inside an archive. The new
3515 implementation is significantly faster and can be wrapped in a
3516 ``io.BufferedReader`` object for more speedups. It also solves an issue
3517 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3530 encoded string for them. This ensures that the upload and register commands
3531 send the correct values to PyPI without any error.

3606-----------------
3607
Georg Brandlba83f822010-03-14 09:50:54 +00003608- The ``__complex__()`` method is now looked up on the class of instances to
3609 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003610
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003611- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3612 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3613
Mark Dickinson1b34d252010-01-01 17:27:30 +00003614- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003615 DeprecationWarning when passed a float argument where an integer was expected.
3616 These functions and methods now raise TypeError instead. The majority of the
3617 effects of this change are in the extension modules, but some core functions
3618 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3619 and many unicode/str methods.

3630 used to drop the time part of the result.
3631
Georg Brandlba83f822010-03-14 09:50:54 +00003632- Issue #1811: Improve accuracy and cross-platform consistency for true division
3633 of integers: the result of a/b is now correctly rounded for ints a and b (at
3634 least on IEEE 754 platforms), and in particular does not depend on the
3635 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003636
Georg Brandlba83f822010-03-14 09:50:54 +00003637- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00003642 executables on OSX.
3643
Georg Brandlba83f822010-03-14 09:50:54 +00003644 These executables now work properly with the arch(1) command: ``arch -ppc
3645 python`` will start a universal binary version of python in PPC mode (unlike
3646 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00003669 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00003817 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3818 providing correctly-rounded strtod and dtoa C functions. This code is
3819 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3820 the C compiler. There may be a small number of platforms on which correct
3821 operation of this code cannot be guaranteed, so the code is not used: notably,
3822 this applies to platforms where the C double format is not IEEE 754 binary64,
3823 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3824 and Python's configure script is unable to determine how to change the FPU
3825 precision. On these platforms conversions use the platform strtod and dtoa,
3826 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003828- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3829 uses the correctly-rounded string <-> float conversions described above (when
3830 available), and so produces correctly rounded results that will display nicely
3831 under the float repr. There are two related small changes: (1) round now
3832 accepts any class with an ``__index__()`` method for its second argument (but
3833 no longer accepts floats for the second argument), and (2) an excessively
3834 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3835 raises an exception.

4214 this code path is really executed because I cannot move to such directory on

4241 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00005412 - Packing a float now always gives a Deprecation Warning. Previously it
5413 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00005415 - If x is not an int, long or float, then packing x will always result in
5416 struct.error. Previously an x with an __int__ method could be packed by
5417 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5418 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5419 neither __int__ nor __long__, TypeError used to be raised (with a
5420 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5421 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00005422
Georg Brandlba83f822010-03-14 09:50:54 +00005423 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
5424 argument with an __int__ method can be packed, but use of this feature
5425 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005618- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5619 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5620 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5621 ``printf`` function, whereas PyString_FromFormat has an independent
5622 implementation and uses "%zd" on all platforms for size_t values.
5623 This makes a difference on win64, where ``printf`` needs "%Id" to display
5624 64bit values.

5630 object; previously an int would be returned for small values. the __long__
5631 method is allowed to return either an int or a long, but the behaviour of

5647 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5648 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005787What's New in Python 2.6 beta 3?
5788================================
5789
Barry Warsaw07a4a382008-08-21 01:15:08 +00005790*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005791
5792Core and Builtins
5793-----------------
5794
Guido van Rossumf8402962008-08-20 15:01:50 +00005795- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5796 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5797 extensions do not automatically benefit from the class attribute
5798 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5799 to their tp_flags field if they care. This is a backwards
5800 compatibility feature; in 3.0, all types will use the cache by
5801 default.
5802
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005803- Keyword arguments can now follow starred arguments. (``f(a, *args,
5804 keyword=23)`` is now valid syntax.)
5805
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005806- ctypes function pointers that are COM methods have a boolean True
5807 value again.
5808
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005809- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5810 by denying s# to parse objects that have a releasebuffer procedure,
5811 and introducing s*.
5812
Georg Brandl1e13ea92008-08-11 09:07:59 +00005813- Issue #3537: Fix an assertion failure when an empty but presized dict
5814 object was stored in the freelist.
5815
Mark Dickinsonb6467572008-08-04 21:30:09 +00005816- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5817 ValueError consistently across platforms.
5818
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005819- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5820 (64bit Unix, for example), unichr() would truncate its argument and return
5821 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5822
Neal Norwitze7d8be82008-07-31 17:17:14 +00005823- Apply security patches from Apple.
5824
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005825- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5826 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5827
Antoine Pitrou92f82162008-07-25 22:22:08 +00005828- Issue #1819: function calls with several named parameters are now on
5829 average 35% faster (as measured by pybench).
5830
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005831- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5832 the python debugger steps into a class statement: the free variables (local
5833 variables defined in an outer scope) would be deleted from the outer scope.
5834
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005835- Issue #2620: Overflow checking when allocating or reallocating memory
5836 was not always being done properly in some python types and extension
5837 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5838 all been updated to perform better checks and places in the code that
5839 would previously leak memory on the error path when such an allocation
5840 failed have been fixed.

5843-------
5844
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005845- Issue #3612: Added some missing basic types in ctypes.wintypes.
5846
Benjamin Petersone977ad42008-08-20 01:42:01 +00005847- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5848 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5849
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005850- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5851 version reported by these tools does not necessarily follow the python
5852 version numbering scheme, so the module is less strict when parsing it.
5853
Nick Coghlanf70385a2008-08-18 12:42:46 +00005854- Issue #2235: Added Py3k warnings for types which will become unhashable
5855 under the stricter __hash__ inheritance rules in 3.0. Several types
5856 which did not meet the rules for hash invariants and were already
5857 unhashable in 3.0 have now been explicitly flagged as unhashable in
5858 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5859 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5860
Brett Cannon88f801d2008-08-18 00:46:22 +00005861- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5862 imported into the module but exposed as part of the module's API.
5863
Brett Cannon7b96f072008-08-18 00:41:11 +00005864- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5865
Brett Cannon46225e72008-08-18 00:36:52 +00005866- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005868- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5869
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005870- Issue #3575: Incremental decoder's decode function now takes bytearray
5871 by using 's*' instead of 't#'.
5872
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005873- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005874 fails unicode conversion on 2nd parameter. (windows only)
5875
Georg Brandl222e2082010-08-01 22:27:39 +00005876- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005877 in a redirect.
5878
Brett Cannonabe423e2008-08-16 21:47:07 +00005879- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005880 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005881
Facundo Batistaeb90b782008-08-16 14:44:07 +00005882- Issue #2776: fixed small issue when handling an URL with double slash
5883 after a 302 response in the case of not going through a proxy.
5884
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005885- Issue #2676: in the email package, content-type parsing was hanging on
5886 pathological input because of quadratic or exponential behaviour of a
5887 regular expression.
5888
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005889- Issue #3476: binary buffered reading through the new "io" library is now
5890 thread-safe.
5891
Brett Cannonbf3157b2008-08-14 05:00:03 +00005892- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5893 since mimetools itself is deprecated. Because modules are cached, all
5894 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5895
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005896- Issue #3134: shutil referenced undefined WindowsError symbol.
5897
Robert Schuppenies14646332008-08-10 11:01:53 +00005898- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5899 menu entries were not deleted.
5900
Brett Cannon83e81842008-08-09 23:30:55 +00005901- Copied the implementation of reduce() to _functools.reduce() to have a
5902 version that did not raise a DeprecationWarning under -3.
5903
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005904- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5905 a MemoryError rather than silently stop the iteration.
5906
Guido van Rossum59ce9012008-08-09 14:55:34 +00005907- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5908 to _sre.compile() will now be rejected. This should not affect anybody
5909 since the re.compile() function never generates invalid re-bytecode.
5910
Skip Montanaroa032bf42008-08-08 22:52:51 +00005911- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5912 upon first access it can be automatically initialized from the csv file if
5913 it wasn't initialized during instantiation.
5914
Brett Cannon3aa2a492008-08-06 22:28:09 +00005915- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5916 the reload() built-in has been removed.
5917
Brett Cannon7e30b672008-08-04 21:52:25 +00005918- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005919 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005930 asking for a specific length. This problem only affected files opened
5931 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005932

5959
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005960- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005981What's New in Python 2.6 beta 2?
5982================================
5983
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005984*Release date: 17-Jul-2008*
5985
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005986Core and Builtins
5987-----------------
5988
Georg Brandl3e483f62008-07-16 22:57:41 +00005989- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5990 its methods now allow for items objects that can be converted to
5991 an integer using operator.index().
5992
Mark Dickinson64b7e502008-07-16 09:40:03 +00005993- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5994 produced a ValueError instead of giving the correct float.
5995
Eric Smitha5fa5a22008-07-16 00:11:49 +00005996- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5997 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5998
Mark Dickinson7103aa42008-07-15 19:08:33 +00005999- Issue #3008: the float type has a new instance method 'float.hex'
6000 and a new class method 'float.fromhex' to convert floating-point
6001 numbers to and from hexadecimal strings, respectively.
6002
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006003- Issue #2235: __hash__ is once again inherited by default. To allow
6004 collections.Hashable to remain meaningful in the presence of the
6005 default hash implementation (object.__hash__), it is now possible
6006 to explicit block inheritance of hash by setting __hash__=None at
6007 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6008 level.
6009
Nick Coghlanb028f502008-07-13 14:52:36 +00006010- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6011 the parent module cannot be found while performing an absolute import.
6012 This means that an incorrectly defined __package__ attribute will
6013 now only prevent relative imports in that module rather than causing
6014 all imports from that module to fail.
6015
Nick Coghlan14ff9942008-07-08 14:21:42 +00006016- Issue #2517: Allow unicode messages in Exceptions again by correctly
6017 bypassing the instance dictionary when looking up __unicode__ on
6018 new-style classes.
6019
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006020- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6021 set to a custom object whose write() method happens to install
6022 another file in sys.stdout.
6023
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006024- Issue #3088: Corrected a race condition in classes derived from
6025 threading.local: the first member set by a thread could be saved in
6026 another thread's dictionary.
6027
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006028- Issue #3004: Minor change to slice.indices(): the start and stop
6029 arguments are now treated identically, making the behaviour easier
6030 to describe and understand. For example, slice(None, -10,
6031 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6032 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6033 10, -1).
6034
Georg Brandl278fc502008-07-19 12:46:12 +00006035- Issue #3219: Calling a function with repeated keyword arguments,
6036 f(a=2, a=23), would not cause a syntax error. This was a regression
6037 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006038
Georg Brandl278fc502008-07-19 12:46:12 +00006039- Issue #2862: Make int and float freelist management consistent with
6040 other freelists. Changes their CompactFreeList apis into
6041 ClearFreeList apis and calls them via gc.collect().

6045
Thomas Heller57adf222008-08-14 19:10:48 +00006046- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6047 api functions without holding the GIL, which could lead to a fatal
6048 error when they failed.
6049
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006050- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6059 ForkingPickler.register() to resolve conflict with ctypes.
6060
Vinay Sajip51e65192008-07-18 09:01:10 +00006061- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006062
Thomas Heller880f5292008-07-15 19:39:38 +00006063- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6064 a valid dlerror() message.

6072
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006073- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006074
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006075- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6076 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006077 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006078 content-length. The problem had been corrected in the 2.4 branch, but never
6079 merged into trunk.
6080
Georg Brandle78fbcc2008-07-05 10:13:36 +00006081- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006094- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6095 handling is now the same as that of other special attributes like __name__).
6096
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006097- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6551 using the 'warning's machinery in such places as the parser where
6552 use of pure Python code is not possible. Both the ``showarning()``
6553 and ``formatwarning()`` gain an optional 'line' argument which is
6554 not called by default for backwards-compatibility reasons. Setting
6555 ``warnings.showwarning()`` to an implementation that lacks support
6556 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006619- Issue #2550: The approach used by client/server code for obtaining
6620 ports to listen on in network-oriented tests has been refined in an
6621 effort to facilitate running multiple instances of the entire
6622 regression test suite in parallel without issue.
6623 test_support.bind_port() has been fixed such that it will always
6624 return a unique port -- which wasn't always the case with the
6625 previous implementation, especially if socket options had been set
6626 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6627 new implementation of bind_port() will actually raise an exception
6628 if it is passed an AF_INET/SOCK_STREAM socket with either the
6629 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6630 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6631 the socket it's been passed. This currently only applies to
6632 Windows. This option prevents any other sockets from binding to the
6633 host/port we've bound to, thus removing the possibility of the
6634 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6635 when a second SOCK_STREAM socket binds and accepts to a host/port
6636 that's already been bound by another socket. The optional preferred
6637 port parameter to bind_port() has been removed. Under no
6638 circumstances should tests be hard coding ports!
6639
6640 test_support.find_unused_port() has also been introduced, which will
6641 pass a temporary socket object to bind_port() in order to obtain an
6642 unused port. The temporary socket object is then closed and
6643 deleted, and the port is returned. This method should only be used
6644 for obtaining an unused port in order to pass to an external program
6645 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6646 a parameter to a server-oriented class that doesn't give you direct
6647 access to the underlying socket used.
6648
6649 Finally, test_support.HOST has been introduced, which should be used
6650 for the host argument of any relevant socket calls (i.e. bind and
6651 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006652
6653 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006654 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006655 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6656 test_asynchat and test_socket_ssl.
6657
Georg Brandl3ee81df2008-05-17 18:14:43 +00006658 It is now possible for multiple instances of the regression test
6659 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006938- Added the future_builtins module, which contains hex() and oct().
6939 These are the PEP 3127 version of these functions, designed to be
6940 compatible with the hex() and oct() builtins from Python 3.0. They
6941 differ slightly in their output formats from the existing, unchanged
6942 Python 2.6 builtins. The expected usage of the future_builtins
6943 module is:
6944 from future_builtins import hex, oct
6945
Eric Smith7ef40bf2008-02-20 23:34:22 +00006946- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6947 exponents for exponents with absolute value < 100. Follows C99
6948 standard. This is a change on Windows, which would use 3 digits.
6949 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6950 so that any alterations it does to the resulting string will be
6951 available in stringlib/formatter.h (for float.__format__).
6952
Eric Smith5a3c1352008-02-19 13:21:56 +00006953- Implemented PEP 3101, Advanced String Formatting. This adds a new
6954 builtin format(); a format() method for str and unicode; a
6955 __format__() method to object, str, unicode, int, long, float, and
6956 datetime; the class string.Formatter; and the C API
6957 PyObject_Format().
6958
Georg Brandl3ee81df2008-05-17 18:14:43 +00006959- Fixed several potential crashes, all caused by specially crafted
6960 __del__ methods exploiting objects in temporarily inconsistent
6961 state.

6972 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006973
Georg Brandl3ee81df2008-05-17 18:14:43 +00006974- Issue #2045: Fix an infinite recursion triggered when printing a
6975 subclass of collections.defaultdict, if its default_factory is set
6976 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006977

6987
Georg Brandl3ee81df2008-05-17 18:14:43 +00006988- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

Georg Brandl3ee81df2008-05-17 18:14:43 +00007004- Patch #1473257: generator objects gain a gi_code attribute. This is
7005 the same object as the func_code attribute of the function that
7006 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007007
Georg Brandl3ee81df2008-05-17 18:14:43 +00007008- Issue #1920: "while 0" statements were completely removed by the
7009 compiler, even in the presence of an "else" clause, which is
7010 supposed to be run when the condition is false. Now the compiler
7011 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007012

Georg Brandl3ee81df2008-05-17 18:14:43 +00007036- Patch #1816: Added sys.flags structseq. It exposes the status of
7037 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007038
Georg Brandl3ee81df2008-05-17 18:14:43 +00007039- Objects/structseq.c: Implemented new structseq representation. The
7040 patch makes structseqs (e.g. the return value of os.stat) more
7041 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007042
Georg Brandl3ee81df2008-05-17 18:14:43 +00007043- Patch #1700288: added a type attribute cache that caches method
7044 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007045
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007046- Bug #1776: __import__() no longer accepts filenames on any platform.
7047 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007048
Georg Brandlaed6c662008-01-07 17:25:53 +00007049- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7050
Georg Brandl3ee81df2008-05-17 18:14:43 +00007051- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7052 envvar and sys.dont_write_bytecode attribute. All these can be set
7053 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007054
Georg Brandl3ee81df2008-05-17 18:14:43 +00007055- Improve some exception messages when Windows fails to load an
7056 extension module. Now we get for example '%1 is not a valid Win32
7057 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007058
Georg Brandl3ee81df2008-05-17 18:14:43 +00007059- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007061- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7062 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007063
Christian Heimes0a8143f2007-12-18 23:22:54 +00007064- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007065 and INF. float("nan"), float("inf") and float("-inf") now work on
7066 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007067
Georg Brandl3ee81df2008-05-17 18:14:43 +00007068- Compiler now generates simpler and faster code for dictionary
7069 literals. The oparg for BUILD_MAP now indicates an estimated
7070 dictionary size. There is a new opcode, STORE_MAP, for adding
7071 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007072
Georg Brandl3ee81df2008-05-17 18:14:43 +00007073- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007075- Issue #1620: New property decorator syntax was modifying the
7076 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00007077
Georg Brandl3ee81df2008-05-17 18:14:43 +00007078- Issue #1538: Avoid copying string in split/rsplit if the split char
7079 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007080
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007081- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007082 SystemError.
7083
Nick Coghlanef01d822007-12-03 12:55:17 +00007084- PEP 366: Allow explicit relative imports when executing modules
7085 inside packages with the -m switch via a new module level
7086 __package__ attribute.
7087

7089 running, and if the deallocation of its frames somehow calls the
7090 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007091

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007095 attribute of an empty cell object.
7096
Georg Brandl3ee81df2008-05-17 18:14:43 +00007097- Issue #1460: The utf-7 incremental decoder did not accept truncated
7098 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007099
Georg Brandl3ee81df2008-05-17 18:14:43 +00007100- Patch #1739468: Directories and zipfiles containing a __main__.py
7101 file can now be directly executed by passing their name to the
7102 interpreter. The directory/zipfile is automatically inserted as the
7103 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007104
Georg Brandl3ee81df2008-05-17 18:14:43 +00007105- Issue #1265: Fix a problem with sys.settrace, if the tracing
7106 function uses a generator expression when at the same time the
7107 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007108
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007109- sets and frozensets now have an isdisjoint() method.
7110
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007111- optimize the performance of builtin.sum().
7112
Neal Norwitz44f326e2007-10-05 05:29:17 +00007113- Fix warnings found by the new version of the Coverity checker.
7114
Georg Brandl21e99f42010-03-07 15:23:59 +00007115- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007116 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7117 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007118
Georg Brandl3ee81df2008-05-17 18:14:43 +00007119- Issue #1686386: Tuple's tp_repr did not take into account the
7120 possibility of having a self-referential tuple, which is possible
7121 from C code. Nor did object's tp_str consider that a type's tp_str
7122 could do something that could lead to an inifinite recursion.
7123 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7124 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007125
Georg Brandl3ee81df2008-05-17 18:14:43 +00007126- Issue #1164: It was possible to trigger deadlock when using the
7127 'print' statement to write to a file since the GIL was not released
7128 as needed. Now PyObject_Print() does the right thing along with
7129 various tp_print implementations of the built-in types and those in
7130 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007131
Georg Brandl3ee81df2008-05-17 18:14:43 +00007132- Issue #1147: Exceptions were directly allowing string exceptions in
7133 their throw() method even though string exceptions no longer
7134 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007135
Georg Brandl3ee81df2008-05-17 18:14:43 +00007136- Issue #1096: Prevent a segfault from getting the repr of a very
7137 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007138
Brett Cannon1e534b52007-09-07 04:18:30 +00007139- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007140 PyObject_Call() never calling back out to Python code to trigger
7141 recursion depth updates/checks. Required the creation of a static
7142 RuntimeError instance in case normalizing an exception put the
7143 recursion check value past its limit. Fixes crashers
7144 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007145
Georg Brandl3ee81df2008-05-17 18:14:43 +00007146- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007159- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007160 __*__ attributes. (Some already existed, e.g., __doc__ and
7161 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007162
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007163- Add -3 option to the interpreter to warn about features that are
7164 deprecated and will be changed/removed in Python 3.0.
7165
Georg Brandl2134e752007-05-21 20:34:16 +00007166- Patch #1686487: you can now pass any mapping after '**' in function
7167 calls.
7168
Collin Winter62903052007-05-18 23:11:24 +00007169- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007170 "except E as target:". This is to provide forwards compatibility
7171 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007172
Brett Cannon229cee22007-05-05 01:34:02 +00007173- Deprecate BaseException.message as per PEP 352.
7174
Georg Brandl3ee81df2008-05-17 18:14:43 +00007175- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007176 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007177
Vinay Sajip8549ce32007-05-06 17:53:37 +00007178- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007179 setting a plain string, ie don't expand to single letter identifiers.
7180
Raymond Hettinger13936692007-04-11 18:40:58 +00007181- Request #1191699: Slices can now be pickled.
7182
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007183- Request #1193128: str.translate() now allows a None argument for
7184 translations that only remove characters without re-mapping the
7185 remaining characters.
7186
Georg Brandl5cb76c12007-03-21 09:00:39 +00007187- Patch #1682205: a TypeError while unpacking an iterable is no longer
7188 masked by a generic one with the message "unpack non-sequence".
7189
Neal Norwitzaa754b72007-03-21 06:39:48 +00007190- Remove unused file Python/fmod.c.
7191
Guido van Rossum143b5642007-03-23 04:58:42 +00007192- Bug #1683368: The object.__init__() and object.__new__() methods are
7193 now stricter in rejecting excess arguments. The only time when
7194 either allows excess arguments is when it is not overridden and the
7195 other one is. For backwards compatibility, when both are
7196 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007197 warning later). Also, type.__init__() insists on the same signature
7198 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007199
Georg Brandl3ee81df2008-05-17 18:14:43 +00007200- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7201 object to complex using its __complex__() method before falling back
7202 to the __float__() method. Therefore, the functions in the cmath
7203 module now can operate on objects that define a __complex__()
7204 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007205
Georg Brandl3ee81df2008-05-17 18:14:43 +00007206- Patch #1623563: allow __class__ assignment for classes with
7207 __slots__. The old and the new class are still required to have the
7208 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007209
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Patch #1642547: Fix an error/crash when encountering syntax errors

7214 ``object.__reduce_ex__()`` is called with an object that is faking
7215 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007216
Georg Brandl3ee81df2008-05-17 18:14:43 +00007217- Patch #1680015: Don't modify __slots__ tuple if it contains an

7221
Georg Brandl7b9c5552007-03-12 14:30:05 +00007222- Bug #1678647: write a newline after printing an exception in any
7223 case, even when converting the value to a string failed.
7224
Georg Brandl871f1bc2007-03-12 13:17:36 +00007225- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007226 its argument, if it exists. If not, it will work like before. This
7227 allows customizing the output of dir() in the presence of a
7228 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007229
Collin Winter276887b2007-03-12 16:11:39 +00007230- Patch #922167: Python no longer segfaults when faced with infinitely
7231 self-recursive reload() calls (as reported by bug #742342).
7232
Georg Brandl3ee81df2008-05-17 18:14:43 +00007233- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00007236- Patch #1491866: change the complex() constructor to allow
7237 parthensized forms. This means complex(repr(x)) now works instead of
7238 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007239
Georg Brandlaa2321b2007-03-07 00:40:28 +00007240- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007241 makes the filenames the warning module prints much more sensible
7242 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007243
Georg Brandl49aafc92007-03-07 00:34:46 +00007244- Variant of patch #697613: don't exit the interpreter on a SystemExit
7245 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007246 variable is given, but break into the interactive interpreter just
7247 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00007254
Georg Brandl0fca97a2007-03-05 22:28:08 +00007255- Patch #1674228: when assigning a slice (old-style), check for the
7256 sq_ass_slice instead of the sq_slice slot.
7257
Georg Brandl3ee81df2008-05-17 18:14:43 +00007258- When printing an unraisable error, don't print exceptions. before
7259 the name. This duplicates the behavior whening normally printing
7260 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00007261
Georg Brandl3ee81df2008-05-17 18:14:43 +00007262- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007762- Added a timeout parameter to the constructor of other protocols
7763 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7764 work started with create_connection() and timeout in httplib, and
7765 closes patch #723312.
7766

7768 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007769 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007770

7791
Georg Brandlf66b6032007-03-14 08:27:52 +00007792- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007793 AttributeError instead of an IOError when the server's response
7794 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007795
Georg Brandl3ee81df2008-05-17 18:14:43 +00007796- Patch #957650: "%var%" environment variable references are now
7797 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00007800- Patch #1429539: pdb now correctly initializes the __main__ module
7801 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007802 correctly now.
7803
Georg Brandlbad6f192007-03-13 21:32:56 +00007804- The nonobvious commands.getstatus() function is now deprecated.

7810
Georg Brandl3ee81df2008-05-17 18:14:43 +00007811- Patch #1530482: add pydoc.render_doc() which returns the
7812 documentation for a thing instead of paging it to stdout, which
7813 pydoc.doc() does.

7821 parameter which can be set to False to prevent the default
7822 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007823
Georg Brandl9e6b4702007-03-13 18:15:41 +00007824- Patch #1581073: add a flag to textwrap that prevents the dropping of
7825 whitespace while wrapping.
7826
Georg Brandl92a6bae2007-03-13 17:43:32 +00007827- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007828 are set for invalid interpolation sequences that would lead to
7829 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007830

Georg Brandl3ee81df2008-05-17 18:14:43 +00007845 field names in its exception message if you try to write a record
7846 with a dictionary containing fields not in the CSV field names list.

7872 returned string up to the first NUL character.

7883
Georg Brandl3ee81df2008-05-17 18:14:43 +00007884- unittest now verifies more of its assumptions. In particular,
7885 TestCase and TestSuite subclasses (not instances) are no longer
7886 accepted in TestSuite.addTest(). This should cause no
7887 incompatibility since it never made sense with ordinary subclasses
7888 -- the failure just occurred later, with a more cumbersome
7889 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008278 time so that opening a database previously created with the DB_DUP
8279 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8280 opens. Specifically: dictionary assignment to a DB object will
8281 replace all values for a given key when the database allows
8282 duplicate values. DB users should use DB.put(k, v) when they want
8283 to store duplicates; not DB[k] = v.

8290 characters with ASCII value less than 32. Also, it correctly quotes
8291 dots only if they occur on a single line, as opposed to the previous
8292 behavior of quoting dots if they are the second character of any
8293 line.
