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

159 by Andrew Bennetts.
160
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000161- Issue #9826: OrderedDict.__repr__ can now handle self-referential

Raymond Hettinger20397532010-09-12 02:11:45 +0000169- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
170 This prevents user-created self-referencing ordered dictionaries from
171 becoming permanently uncollectable GC garbage. The downside is that
172 removing __del__ means that the internal doubly-linked list has to wait for
173 GC collection rather than freeing memory immediately when the refcnt drops
174 to zero.
175
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000176- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000177 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000178 value.
179
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000180- Issue #9792: In case of connection failure, socket.create_connection()
181 would swallow the exception and raise a new one, making it impossible
182 to fetch the original errno, or to filter timeout errors. Now the
183 original error is re-raised.
184
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000185- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
186 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
187 be updated back after the system call. Original patch by Brian Brazil.
188
Antoine Pitroudca9de92010-09-04 17:52:26 +0000189- Issue #1100562: Fix deep-copying of objects derived from the list and
190 dict types. Patch by Michele Orrù and Björn Lindqvist.
191
Fred Drakea1e627d2010-09-03 03:55:50 +0000192- Issue #7005: Fixed output of None values for RawConfigParser.write and
193 ConfigParser.write.
194
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000195- Issue #808164: Fixed socket.close to avoid references to globals, to
196 avoid issues when socket.close is called from a __del__ method.
197
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000198- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

200

202 character years even if the message contains RFC822 two character years.
203
Daniel Stutzbach91287322010-08-24 21:09:30 +0000204- Issue #8750: Fixed MutableSet's methods to correctly handle
205 reflexive operations, namely x -= x and x ^= x.
206
Victor Stinnercaafd772010-09-08 10:51:01 +0000207- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000208 error handling when accepting a new connection.
209

216 module now correctly return a set. (Patch by Eli Bendersky.)
217
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000218- Issue #9617: Signals received during a low-level write operation aren't
219 ignored by the buffered IO layer anymore.
220
Benjamin Peterson52c36052010-08-21 03:03:22 +0000221- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
222 are not held onto after they are deleted elsewhere.
223
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000224- Issue #9626: the view methods for collections.OrderedDict() were returning
225 the unordered versions inherited from dict. Those methods are now
226 overridden to provide ordered views.
227
Éric Araujo0389ae62010-08-14 03:07:46 +0000228- Issue #8688: MANIFEST files created by distutils now include a magic
229 comment indicating they are generated. Manually maintained MANIFESTs
230 without this marker will not be overwritten or removed.
231
Antoine Pitroue1436d12010-08-12 15:25:51 +0000232- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

240
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000241- Issue #9551: Don't raise TypeError when setting the value to None for

245 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
246
Antoine Pitrou99009162010-08-09 22:51:24 +0000247- Issue #3757: thread-local objects now support cyclic garbage collection.

260 This is how it is supposed to work, wget and curl do the same. Previous
261 behavior was wrong.

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

627
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000628- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
629 start byte and the continuation byte(s) are now considered invalid, instead
630 of the number of bytes specified by the start byte.
631 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
632 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
633 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
634 Previous versions returned a single u'\ufffd'.
635
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000636- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000637 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
638 arises from the "Overriding __eq__ blocks inheritance ..." warning
639 when turned into an exception: in this case the exception simply
640 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000641
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000642- Issue #8748: Fix two issues with comparisons between complex and integer
643 objects. (1) The comparison could incorrectly return True in some cases
644 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
645 (2) The comparison raised an OverflowError for large integers, leading
646 to unpredictable exceptions when combining integers and complex objects
647 in sets or dicts.
648
Mark Dickinson81336372010-05-30 12:12:25 +0000649- Issue #5211: Implicit coercion for the complex type is now completely
650 removed. (Coercion for arithmetic operations was already removed in 2.7
651 alpha 4, but coercion for rich comparisons was accidentally left in.)
652
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000653- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

655
Georg Brandlfee0f442010-05-22 21:26:21 +0000656- Issue #7902: When using explicit relative import syntax, don't try implicit

669 of the interpreter to set sys.argv without also modifying sys.path. This
670 helps fix `CVE-2008-5983

894 indefinitely if the other end didn't respond.
895
Georg Brandlfee0f442010-05-22 21:26:21 +0000896- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000989 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001014- Issue #7301: Add environment variable $PYTHONWARNINGS.
1015
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001016- Issue #8329: Don't return the same lists from select.select when no fds are
1017 changed.
1018
Georg Brandlfee0f442010-05-22 21:26:21 +00001019- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001020 on 64-bit machines. The shift count for either left or right shift is
1021 permitted to be up to sys.maxsize.
1022
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001023- Ensure that tokenization of identifiers is not affected by locale.

1028
Georg Brandlfee0f442010-05-22 21:26:21 +00001029- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1030 with a non-empty format string. This is an effort to future-proof user
1031 code. If a derived class does not currently implement __format__ but later
1032 adds its own __format__, it would most likely break user code that had
1033 supplied a format string. This will be changed to a DeprecationWaring in
1034 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001035

Georg Brandlfee0f442010-05-22 21:26:21 +00001067- Issue #8257: The Decimal construct now accepts a float instance directly,
1068 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001069

Raymond Hettinger34c35b22010-04-03 10:22:00 +00001073- collections.Counter() now supports a subtract() method.
1074
Georg Brandlfee0f442010-05-22 21:26:21 +00001075- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00001084- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1085 InvalidOperation instead of returning False. (Comparisons involving a quiet
1086 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1087 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001089- Issue #2531: Comparison operations between floats and Decimal instances now
1090 return a result based on the numeric values of the operands; previously they
1091 returned an arbitrary result based on the relative ordering of id(float) and
1092 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001094- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001095 argument `-` which tells it to read files to compile from stdin. Each line is
1096 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001106- Comparisons using one of <, <=, >, >= between a complex instance and a
1107 Fractions instance now raise TypeError instead of returning True/False. This
1108 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1109 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001516 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00001523 file position when calling `truncate()`. It would previously change the file
1524 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001525 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1528 class used to represent files stored inside an archive. The new
1529 implementation is significantly faster and can be wrapped in a
1530 ``io.BufferedReader`` object for more speedups. It also solves an issue
1531 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1621
Georg Brandlba83f822010-03-14 09:50:54 +00001622- The ``__complex__()`` method is now looked up on the class of instances to
1623 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001625- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1626 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1627
Mark Dickinson1b34d252010-01-01 17:27:30 +00001628- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001629 DeprecationWarning when passed a float argument where an integer was expected.
1630 These functions and methods now raise TypeError instead. The majority of the
1631 effects of this change are in the extension modules, but some core functions
1632 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1633 and many unicode/str methods.

1644 used to drop the time part of the result.
1645
Georg Brandlba83f822010-03-14 09:50:54 +00001646- Issue #1811: Improve accuracy and cross-platform consistency for true division
1647 of integers: the result of a/b is now correctly rounded for ints a and b (at
1648 least on IEEE 754 platforms), and in particular does not depend on the
1649 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001656 executables on OSX.
1657
Georg Brandlba83f822010-03-14 09:50:54 +00001658 These executables now work properly with the arch(1) command: ``arch -ppc
1659 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00001683 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00001831 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1832 providing correctly-rounded strtod and dtoa C functions. This code is
1833 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1834 the C compiler. There may be a small number of platforms on which correct
1835 operation of this code cannot be guaranteed, so the code is not used: notably,
1836 this applies to platforms where the C double format is not IEEE 754 binary64,
1837 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1838 and Python's configure script is unable to determine how to change the FPU
1839 precision. On these platforms conversions use the platform strtod and dtoa,
1840 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001842- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1843 uses the correctly-rounded string <-> float conversions described above (when
1844 available), and so produces correctly rounded results that will display nicely
1845 under the float repr. There are two related small changes: (1) round now
1846 accepts any class with an ``__index__()`` method for its second argument (but
1847 no longer accepts floats for the second argument), and (2) an excessively
1848 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1849 raises an exception.

2228 this code path is really executed because I cannot move to such directory on

3431 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3432 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3433 neither __int__ nor __long__, TypeError used to be raised (with a
3434 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3435 struct.error in other cases.

3438 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003632- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3633 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3634 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3635 ``printf`` function, whereas PyString_FromFormat has an independent
3636 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003733 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3734 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003801What's New in Python 2.6 beta 3?
3802================================
3803
Barry Warsaw07a4a382008-08-21 01:15:08 +00003804*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003805
3806Core and Builtins
3807-----------------
3808
Guido van Rossumf8402962008-08-20 15:01:50 +00003809- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3810 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3811 extensions do not automatically benefit from the class attribute
3812 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3813 to their tp_flags field if they care. This is a backwards
3814 compatibility feature; in 3.0, all types will use the cache by
3815 default.
3816
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003817- Keyword arguments can now follow starred arguments. (``f(a, *args,
3818 keyword=23)`` is now valid syntax.)
3819
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003820- ctypes function pointers that are COM methods have a boolean True
3821 value again.
3822
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003823- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3824 by denying s# to parse objects that have a releasebuffer procedure,
3825 and introducing s*.
3826
Georg Brandl1e13ea92008-08-11 09:07:59 +00003827- Issue #3537: Fix an assertion failure when an empty but presized dict
3828 object was stored in the freelist.
3829
Mark Dickinsonb6467572008-08-04 21:30:09 +00003830- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3831 ValueError consistently across platforms.
3832
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003833- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3834 (64bit Unix, for example), unichr() would truncate its argument and return
3835 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3836
Neal Norwitze7d8be82008-07-31 17:17:14 +00003837- Apply security patches from Apple.
3838
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003839- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3840 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3841
Antoine Pitrou92f82162008-07-25 22:22:08 +00003842- Issue #1819: function calls with several named parameters are now on
3843 average 35% faster (as measured by pybench).
3844
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003845- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3846 the python debugger steps into a class statement: the free variables (local
3847 variables defined in an outer scope) would be deleted from the outer scope.
3848
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003849- Issue #2620: Overflow checking when allocating or reallocating memory
3850 was not always being done properly in some python types and extension
3851 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3852 all been updated to perform better checks and places in the code that
3853 would previously leak memory on the error path when such an allocation
3854 failed have been fixed.

3857-------
3858
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003859- Issue #3612: Added some missing basic types in ctypes.wintypes.
3860
Benjamin Petersone977ad42008-08-20 01:42:01 +00003861- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3862 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3863
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003864- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3865 version reported by these tools does not necessarily follow the python
3866 version numbering scheme, so the module is less strict when parsing it.
3867
Nick Coghlanf70385a2008-08-18 12:42:46 +00003868- Issue #2235: Added Py3k warnings for types which will become unhashable
3869 under the stricter __hash__ inheritance rules in 3.0. Several types
3870 which did not meet the rules for hash invariants and were already
3871 unhashable in 3.0 have now been explicitly flagged as unhashable in
3872 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3873 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3874
Brett Cannon88f801d2008-08-18 00:46:22 +00003875- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3876 imported into the module but exposed as part of the module's API.
3877
Brett Cannon7b96f072008-08-18 00:41:11 +00003878- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3879
Brett Cannon46225e72008-08-18 00:36:52 +00003880- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003882- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3883
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003884- Issue #3575: Incremental decoder's decode function now takes bytearray
3885 by using 's*' instead of 't#'.
3886
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003887- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003888 fails unicode conversion on 2nd parameter. (windows only)
3889
Georg Brandl222e2082010-08-01 22:27:39 +00003890- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003891 in a redirect.
3892
Brett Cannonabe423e2008-08-16 21:47:07 +00003893- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003894 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003895
Facundo Batistaeb90b782008-08-16 14:44:07 +00003896- Issue #2776: fixed small issue when handling an URL with double slash
3897 after a 302 response in the case of not going through a proxy.
3898
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003899- Issue #2676: in the email package, content-type parsing was hanging on
3900 pathological input because of quadratic or exponential behaviour of a
3901 regular expression.
3902
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003903- Issue #3476: binary buffered reading through the new "io" library is now
3904 thread-safe.
3905
Brett Cannonbf3157b2008-08-14 05:00:03 +00003906- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3907 since mimetools itself is deprecated. Because modules are cached, all
3908 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3909
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003910- Issue #3134: shutil referenced undefined WindowsError symbol.
3911
Robert Schuppenies14646332008-08-10 11:01:53 +00003912- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3913 menu entries were not deleted.
3914
Brett Cannon83e81842008-08-09 23:30:55 +00003915- Copied the implementation of reduce() to _functools.reduce() to have a
3916 version that did not raise a DeprecationWarning under -3.
3917
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003918- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3919 a MemoryError rather than silently stop the iteration.
3920
Guido van Rossum59ce9012008-08-09 14:55:34 +00003921- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3922 to _sre.compile() will now be rejected. This should not affect anybody
3923 since the re.compile() function never generates invalid re-bytecode.
3924
Skip Montanaroa032bf42008-08-08 22:52:51 +00003925- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3926 upon first access it can be automatically initialized from the csv file if
3927 it wasn't initialized during instantiation.
3928
Brett Cannon3aa2a492008-08-06 22:28:09 +00003929- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3930 the reload() built-in has been removed.
3931
Brett Cannon7e30b672008-08-04 21:52:25 +00003932- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003933 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003944 asking for a specific length. This problem only affected files opened
3945 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003946

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004000Core and Builtins
4001-----------------
4002
Georg Brandl3e483f62008-07-16 22:57:41 +00004003- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4004 its methods now allow for items objects that can be converted to
4005 an integer using operator.index().
4006
Mark Dickinson64b7e502008-07-16 09:40:03 +00004007- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4008 produced a ValueError instead of giving the correct float.
4009
Eric Smitha5fa5a22008-07-16 00:11:49 +00004010- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4011 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4012
Mark Dickinson7103aa42008-07-15 19:08:33 +00004013- Issue #3008: the float type has a new instance method 'float.hex'
4014 and a new class method 'float.fromhex' to convert floating-point
4015 numbers to and from hexadecimal strings, respectively.
4016
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004017- Issue #2235: __hash__ is once again inherited by default. To allow
4018 collections.Hashable to remain meaningful in the presence of the
4019 default hash implementation (object.__hash__), it is now possible
4020 to explicit block inheritance of hash by setting __hash__=None at
4021 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4022 level.
4023
Nick Coghlanb028f502008-07-13 14:52:36 +00004024- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4025 the parent module cannot be found while performing an absolute import.
4026 This means that an incorrectly defined __package__ attribute will
4027 now only prevent relative imports in that module rather than causing
4028 all imports from that module to fail.
4029
Nick Coghlan14ff9942008-07-08 14:21:42 +00004030- Issue #2517: Allow unicode messages in Exceptions again by correctly
4031 bypassing the instance dictionary when looking up __unicode__ on
4032 new-style classes.
4033
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004034- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4035 set to a custom object whose write() method happens to install
4036 another file in sys.stdout.
4037
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004038- Issue #3088: Corrected a race condition in classes derived from
4039 threading.local: the first member set by a thread could be saved in
4040 another thread's dictionary.
4041
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004042- Issue #3004: Minor change to slice.indices(): the start and stop
4043 arguments are now treated identically, making the behaviour easier
4044 to describe and understand. For example, slice(None, -10,
4045 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4046 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4047 10, -1).
4048
Georg Brandl278fc502008-07-19 12:46:12 +00004049- Issue #3219: Calling a function with repeated keyword arguments,
4050 f(a=2, a=23), would not cause a syntax error. This was a regression
4051 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004052
Georg Brandl278fc502008-07-19 12:46:12 +00004053- Issue #2862: Make int and float freelist management consistent with
4054 other freelists. Changes their CompactFreeList apis into
4055 ClearFreeList apis and calls them via gc.collect().

4059
Thomas Heller57adf222008-08-14 19:10:48 +00004060- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4061 api functions without holding the GIL, which could lead to a fatal
4062 error when they failed.
4063
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004064- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4073 ForkingPickler.register() to resolve conflict with ctypes.
4074
Vinay Sajip51e65192008-07-18 09:01:10 +00004075- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004076
Thomas Heller880f5292008-07-15 19:39:38 +00004077- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4078 a valid dlerror() message.
4079
Thomas Heller2bad6572008-07-15 17:19:50 +00004080- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4081 incomplete structure was created.

4086
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004087- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004088
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004089- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4090 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004091 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004092 content-length. The problem had been corrected in the 2.4 branch, but never
4093 merged into trunk.
4094
Georg Brandle78fbcc2008-07-05 10:13:36 +00004095- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004108- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4109 handling is now the same as that of other special attributes like __name__).
4110
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004111- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

4565 using the 'warning's machinery in such places as the parser where
4566 use of pure Python code is not possible. Both the ``showarning()``
4567 and ``formatwarning()`` gain an optional 'line' argument which is
4568 not called by default for backwards-compatibility reasons. Setting
4569 ``warnings.showwarning()`` to an implementation that lacks support
4570 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004633- Issue #2550: The approach used by client/server code for obtaining
4634 ports to listen on in network-oriented tests has been refined in an
4635 effort to facilitate running multiple instances of the entire
4636 regression test suite in parallel without issue.
4637 test_support.bind_port() has been fixed such that it will always
4638 return a unique port -- which wasn't always the case with the
4639 previous implementation, especially if socket options had been set
4640 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4641 new implementation of bind_port() will actually raise an exception
4642 if it is passed an AF_INET/SOCK_STREAM socket with either the
4643 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4644 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4645 the socket it's been passed. This currently only applies to
4646 Windows. This option prevents any other sockets from binding to the
4647 host/port we've bound to, thus removing the possibility of the
4648 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4649 when a second SOCK_STREAM socket binds and accepts to a host/port
4650 that's already been bound by another socket. The optional preferred
4651 port parameter to bind_port() has been removed. Under no
4652 circumstances should tests be hard coding ports!
4653
4654 test_support.find_unused_port() has also been introduced, which will
4655 pass a temporary socket object to bind_port() in order to obtain an
4656 unused port. The temporary socket object is then closed and
4657 deleted, and the port is returned. This method should only be used
4658 for obtaining an unused port in order to pass to an external program
4659 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4660 a parameter to a server-oriented class that doesn't give you direct
4661 access to the underlying socket used.
4662
4663 Finally, test_support.HOST has been introduced, which should be used
4664 for the host argument of any relevant socket calls (i.e. bind and
4665 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004666
4667 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004668 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004669 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4670 test_asynchat and test_socket_ssl.
4671
Georg Brandl3ee81df2008-05-17 18:14:43 +00004672 It is now possible for multiple instances of the regression test
4673 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004952- Added the future_builtins module, which contains hex() and oct().
4953 These are the PEP 3127 version of these functions, designed to be
4954 compatible with the hex() and oct() builtins from Python 3.0. They
4955 differ slightly in their output formats from the existing, unchanged
4956 Python 2.6 builtins. The expected usage of the future_builtins
4957 module is:
4958 from future_builtins import hex, oct
4959
Eric Smith7ef40bf2008-02-20 23:34:22 +00004960- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4961 exponents for exponents with absolute value < 100. Follows C99
4962 standard. This is a change on Windows, which would use 3 digits.
4963 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4964 so that any alterations it does to the resulting string will be
4965 available in stringlib/formatter.h (for float.__format__).
4966
Eric Smith5a3c1352008-02-19 13:21:56 +00004967- Implemented PEP 3101, Advanced String Formatting. This adds a new
4968 builtin format(); a format() method for str and unicode; a
4969 __format__() method to object, str, unicode, int, long, float, and
4970 datetime; the class string.Formatter; and the C API
4971 PyObject_Format().
4972
Georg Brandl3ee81df2008-05-17 18:14:43 +00004973- Fixed several potential crashes, all caused by specially crafted
4974 __del__ methods exploiting objects in temporarily inconsistent
4975 state.

4986 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004987
Georg Brandl3ee81df2008-05-17 18:14:43 +00004988- Issue #2045: Fix an infinite recursion triggered when printing a
4989 subclass of collections.defaultdict, if its default_factory is set
4990 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005018- Patch #1473257: generator objects gain a gi_code attribute. This is
5019 the same object as the func_code attribute of the function that
5020 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005021
Georg Brandl3ee81df2008-05-17 18:14:43 +00005022- Issue #1920: "while 0" statements were completely removed by the
5023 compiler, even in the presence of an "else" clause, which is
5024 supposed to be run when the condition is false. Now the compiler
5025 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005026

Georg Brandl3ee81df2008-05-17 18:14:43 +00005050- Patch #1816: Added sys.flags structseq. It exposes the status of
5051 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005052
Georg Brandl3ee81df2008-05-17 18:14:43 +00005053- Objects/structseq.c: Implemented new structseq representation. The
5054 patch makes structseqs (e.g. the return value of os.stat) more
5055 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005056
Georg Brandl3ee81df2008-05-17 18:14:43 +00005057- Patch #1700288: added a type attribute cache that caches method
5058 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005059
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005060- Bug #1776: __import__() no longer accepts filenames on any platform.
5061 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005062
Georg Brandlaed6c662008-01-07 17:25:53 +00005063- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5064
Georg Brandl3ee81df2008-05-17 18:14:43 +00005065- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5066 envvar and sys.dont_write_bytecode attribute. All these can be set
5067 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005068
Georg Brandl3ee81df2008-05-17 18:14:43 +00005069- Improve some exception messages when Windows fails to load an
5070 extension module. Now we get for example '%1 is not a valid Win32
5071 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005072
Georg Brandl3ee81df2008-05-17 18:14:43 +00005073- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005075- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5076 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005077
Christian Heimes0a8143f2007-12-18 23:22:54 +00005078- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005079 and INF. float("nan"), float("inf") and float("-inf") now work on
5080 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005081
Georg Brandl3ee81df2008-05-17 18:14:43 +00005082- Compiler now generates simpler and faster code for dictionary
5083 literals. The oparg for BUILD_MAP now indicates an estimated
5084 dictionary size. There is a new opcode, STORE_MAP, for adding
5085 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005092- Issue #1538: Avoid copying string in split/rsplit if the split char
5093 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00005094
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005095- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005096 SystemError.
5097
Nick Coghlanef01d822007-12-03 12:55:17 +00005098- PEP 366: Allow explicit relative imports when executing modules
5099 inside packages with the -m switch via a new module level
5100 __package__ attribute.

5103 running, and if the deallocation of its frames somehow calls the
5104 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005105

5110
Georg Brandl3ee81df2008-05-17 18:14:43 +00005111- Issue #1460: The utf-7 incremental decoder did not accept truncated
5112 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005113
Georg Brandl3ee81df2008-05-17 18:14:43 +00005114- Patch #1739468: Directories and zipfiles containing a __main__.py
5115 file can now be directly executed by passing their name to the
5116 interpreter. The directory/zipfile is automatically inserted as the
5117 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005118
Georg Brandl3ee81df2008-05-17 18:14:43 +00005119- Issue #1265: Fix a problem with sys.settrace, if the tracing
5120 function uses a generator expression when at the same time the
5121 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005122
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005123- sets and frozensets now have an isdisjoint() method.
5124
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005125- optimize the performance of builtin.sum().
5126
Neal Norwitz44f326e2007-10-05 05:29:17 +00005127- Fix warnings found by the new version of the Coverity checker.
5128
Georg Brandl21e99f42010-03-07 15:23:59 +00005129- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005130 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5131 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005132
Georg Brandl3ee81df2008-05-17 18:14:43 +00005133- Issue #1686386: Tuple's tp_repr did not take into account the
5134 possibility of having a self-referential tuple, which is possible
5135 from C code. Nor did object's tp_str consider that a type's tp_str
5136 could do something that could lead to an inifinite recursion.
5137 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5138 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005139
Georg Brandl3ee81df2008-05-17 18:14:43 +00005140- Issue #1164: It was possible to trigger deadlock when using the
5141 'print' statement to write to a file since the GIL was not released
5142 as needed. Now PyObject_Print() does the right thing along with
5143 various tp_print implementations of the built-in types and those in
5144 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005145
Georg Brandl3ee81df2008-05-17 18:14:43 +00005146- Issue #1147: Exceptions were directly allowing string exceptions in
5147 their throw() method even though string exceptions no longer
5148 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005149
Georg Brandl3ee81df2008-05-17 18:14:43 +00005150- Issue #1096: Prevent a segfault from getting the repr of a very
5151 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005152
Brett Cannon1e534b52007-09-07 04:18:30 +00005153- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005154 PyObject_Call() never calling back out to Python code to trigger
5155 recursion depth updates/checks. Required the creation of a static
5156 RuntimeError instance in case normalizing an exception put the
5157 recursion check value past its limit. Fixes crashers
5158 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005159
Georg Brandl3ee81df2008-05-17 18:14:43 +00005160- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005173- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005174 __*__ attributes. (Some already existed, e.g., __doc__ and
5175 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005176
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005177- Add -3 option to the interpreter to warn about features that are
5178 deprecated and will be changed/removed in Python 3.0.
5179
Georg Brandl2134e752007-05-21 20:34:16 +00005180- Patch #1686487: you can now pass any mapping after '**' in function
5181 calls.
5182
Collin Winter62903052007-05-18 23:11:24 +00005183- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005184 "except E as target:". This is to provide forwards compatibility
5185 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005186
Brett Cannon229cee22007-05-05 01:34:02 +00005187- Deprecate BaseException.message as per PEP 352.
5188
Georg Brandl3ee81df2008-05-17 18:14:43 +00005189- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005190 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005191
Vinay Sajip8549ce32007-05-06 17:53:37 +00005192- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005193 setting a plain string, ie don't expand to single letter identifiers.
5194
Raymond Hettinger13936692007-04-11 18:40:58 +00005195- Request #1191699: Slices can now be pickled.
5196
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005197- Request #1193128: str.translate() now allows a None argument for
5198 translations that only remove characters without re-mapping the
5199 remaining characters.
5200
Georg Brandl5cb76c12007-03-21 09:00:39 +00005201- Patch #1682205: a TypeError while unpacking an iterable is no longer
5202 masked by a generic one with the message "unpack non-sequence".
5203
Neal Norwitzaa754b72007-03-21 06:39:48 +00005204- Remove unused file Python/fmod.c.
5205
Guido van Rossum143b5642007-03-23 04:58:42 +00005206- Bug #1683368: The object.__init__() and object.__new__() methods are
5207 now stricter in rejecting excess arguments. The only time when
5208 either allows excess arguments is when it is not overridden and the
5209 other one is. For backwards compatibility, when both are
5210 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005211 warning later). Also, type.__init__() insists on the same signature
5212 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005213
Georg Brandl3ee81df2008-05-17 18:14:43 +00005214- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5215 object to complex using its __complex__() method before falling back
5216 to the __float__() method. Therefore, the functions in the cmath
5217 module now can operate on objects that define a __complex__()
5218 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005219
Georg Brandl3ee81df2008-05-17 18:14:43 +00005220- Patch #1623563: allow __class__ assignment for classes with
5221 __slots__. The old and the new class are still required to have the
5222 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005223
Georg Brandl3ee81df2008-05-17 18:14:43 +00005224- Patch #1642547: Fix an error/crash when encountering syntax errors

5228 ``object.__reduce_ex__()`` is called with an object that is faking
5229 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005230
Georg Brandl3ee81df2008-05-17 18:14:43 +00005231- Patch #1680015: Don't modify __slots__ tuple if it contains an

5235
Georg Brandl7b9c5552007-03-12 14:30:05 +00005236- Bug #1678647: write a newline after printing an exception in any
5237 case, even when converting the value to a string failed.
5238
Georg Brandl871f1bc2007-03-12 13:17:36 +00005239- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005240 its argument, if it exists. If not, it will work like before. This
5241 allows customizing the output of dir() in the presence of a
5242 __getattr__().

5246
Georg Brandl3ee81df2008-05-17 18:14:43 +00005247- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005250- Patch #1491866: change the complex() constructor to allow
5251 parthensized forms. This means complex(repr(x)) now works instead of
5252 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005253
Georg Brandlaa2321b2007-03-07 00:40:28 +00005254- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005255 makes the filenames the warning module prints much more sensible
5256 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005257

5259 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005260 variable is given, but break into the interactive interpreter just
5261 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00005268
Georg Brandl0fca97a2007-03-05 22:28:08 +00005269- Patch #1674228: when assigning a slice (old-style), check for the
5270 sq_ass_slice instead of the sq_slice slot.
5271
Georg Brandl3ee81df2008-05-17 18:14:43 +00005272- When printing an unraisable error, don't print exceptions. before
5273 the name. This duplicates the behavior whening normally printing
5274 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00005275

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005776- Added a timeout parameter to the constructor of other protocols
5777 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5778 work started with create_connection() and timeout in httplib, and
5779 closes patch #723312.
5780

5782 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00005783 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00005784

5805
Georg Brandlf66b6032007-03-14 08:27:52 +00005806- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005807 AttributeError instead of an IOError when the server's response
5808 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005809

Georg Brandl3ee81df2008-05-17 18:14:43 +00005814- Patch #1429539: pdb now correctly initializes the __main__ module
5815 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005816 correctly now.
5817

5824
Georg Brandl3ee81df2008-05-17 18:14:43 +00005825- Patch #1530482: add pydoc.render_doc() which returns the

5835 parameter which can be set to False to prevent the default
5836 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00005837
Georg Brandl9e6b4702007-03-13 18:15:41 +00005838- Patch #1581073: add a flag to textwrap that prevents the dropping of
5839 whitespace while wrapping.
5840
Georg Brandl92a6bae2007-03-13 17:43:32 +00005841- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005842 are set for invalid interpolation sequences that would lead to
5843 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00005844

Georg Brandl3ee81df2008-05-17 18:14:43 +00005859 field names in its exception message if you try to write a record
5860 with a dictionary containing fields not in the CSV field names list.

5886 returned string up to the first NUL character.

5897
Georg Brandl3ee81df2008-05-17 18:14:43 +00005898- unittest now verifies more of its assumptions. In particular,
5899 TestCase and TestSuite subclasses (not instances) are no longer
5900 accepted in TestSuite.addTest(). This should cause no
5901 incompatibility since it never made sense with ordinary subclasses
5902 -- the failure just occurred later, with a more cumbersome
5903 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006292 time so that opening a database previously created with the DB_DUP
6293 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6294 opens. Specifically: dictionary assignment to a DB object will
6295 replace all values for a given key when the database allows
6296 duplicate values. DB users should use DB.put(k, v) when they want
6297 to store duplicates; not DB[k] = v.

6304 characters with ASCII value less than 32. Also, it correctly quotes
6305 dots only if they occur on a single line, as opposed to the previous
6306 behavior of quoting dots if they are the second character of any
6307 line.
