156

161 SSLSocket.sendto() to match the corresponding socket methods. Also,
162 fix various SSLSocket methods to raise socket.error rather than an
163 unhelpful TypeError when called on an unconnected socket. Original patch
164 by Andrew Bennetts.
165
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000166- Issue #9826: OrderedDict.__repr__ can now handle self-referential

Raymond Hettinger20397532010-09-12 02:11:45 +0000174- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
175 This prevents user-created self-referencing ordered dictionaries from
176 becoming permanently uncollectable GC garbage. The downside is that
177 removing __del__ means that the internal doubly-linked list has to wait for
178 GC collection rather than freeing memory immediately when the refcnt drops
179 to zero.
180
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000181- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000182 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000183 value.
184
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000185- Issue #9792: In case of connection failure, socket.create_connection()
186 would swallow the exception and raise a new one, making it impossible
187 to fetch the original errno, or to filter timeout errors. Now the
188 original error is re-raised.
189
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000190- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
191 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
192 be updated back after the system call. Original patch by Brian Brazil.
193
Antoine Pitroudca9de92010-09-04 17:52:26 +0000194- Issue #1100562: Fix deep-copying of objects derived from the list and
195 dict types. Patch by Michele Orrù and Björn Lindqvist.
196
Fred Drakea1e627d2010-09-03 03:55:50 +0000197- Issue #7005: Fixed output of None values for RawConfigParser.write and
198 ConfigParser.write.
199
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000200- Issue #808164: Fixed socket.close to avoid references to globals, to
201 avoid issues when socket.close is called from a __del__ method.
202
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000203- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

207 character years even if the message contains RFC822 two character years.
208
Daniel Stutzbach91287322010-08-24 21:09:30 +0000209- Issue #8750: Fixed MutableSet's methods to correctly handle
210 reflexive operations, namely x -= x and x ^= x.
211
Victor Stinnercaafd772010-09-08 10:51:01 +0000212- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000213 error handling when accepting a new connection.
214
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000215- Issue #658749: asyncore's connect() method now correctly interprets winsock

221 module now correctly return a set. (Patch by Eli Bendersky.)
222
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000223- Issue #9617: Signals received during a low-level write operation aren't
224 ignored by the buffered IO layer anymore.
225
Benjamin Peterson52c36052010-08-21 03:03:22 +0000226- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
227 are not held onto after they are deleted elsewhere.
228
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000229- Issue #9626: the view methods for collections.OrderedDict() were returning
230 the unordered versions inherited from dict. Those methods are now
231 overridden to provide ordered views.
232
Éric Araujo0389ae62010-08-14 03:07:46 +0000233- Issue #8688: MANIFEST files created by distutils now include a magic
234 comment indicating they are generated. Manually maintained MANIFESTs

250 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
251
Antoine Pitrou99009162010-08-09 22:51:24 +0000252- Issue #3757: thread-local objects now support cyclic garbage collection.

632
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000633- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
634 start byte and the continuation byte(s) are now considered invalid, instead
635 of the number of bytes specified by the start byte.
636 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
637 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
638 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
639 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000641- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000642 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
643 arises from the "Overriding __eq__ blocks inheritance ..." warning
644 when turned into an exception: in this case the exception simply
645 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000646
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000647- Issue #8748: Fix two issues with comparisons between complex and integer
648 objects. (1) The comparison could incorrectly return True in some cases
649 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
650 (2) The comparison raised an OverflowError for large integers, leading
651 to unpredictable exceptions when combining integers and complex objects
652 in sets or dicts.
653
Mark Dickinson81336372010-05-30 12:12:25 +0000654- Issue #5211: Implicit coercion for the complex type is now completely
655 removed. (Coercion for arithmetic operations was already removed in 2.7
656 alpha 4, but coercion for rich comparisons was accidentally left in.)
657
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000658- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

1020
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001021- Issue #8329: Don't return the same lists from select.select when no fds are
1022 changed.
1023
Georg Brandlfee0f442010-05-22 21:26:21 +00001024- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001025 on 64-bit machines. The shift count for either left or right shift is
1026 permitted to be up to sys.maxsize.
1027
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001028- Ensure that tokenization of identifiers is not affected by locale.

1033
Georg Brandlfee0f442010-05-22 21:26:21 +00001034- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1035 with a non-empty format string. This is an effort to future-proof user
1036 code. If a derived class does not currently implement __format__ but later
1037 adds its own __format__, it would most likely break user code that had
1038 supplied a format string. This will be changed to a DeprecationWaring in
1039 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001072- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00001080- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00001089- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1090 InvalidOperation instead of returning False. (Comparisons involving a quiet
1091 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1092 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00001094- Issue #2531: Comparison operations between floats and Decimal instances now
1095 return a result based on the numeric values of the operands; previously they
1096 returned an arbitrary result based on the relative ordering of id(float) and
1097 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001111- Comparisons using one of <, <=, >, >= between a complex instance and a
1112 Fractions instance now raise TypeError instead of returning True/False. This
1113 makes Fraction <=> complex comparisons consistent with int <=> complex, float

Georg Brandlba83f822010-03-14 09:50:54 +00001528 file position when calling `truncate()`. It would previously change the file
1529 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001530 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1533 class used to represent files stored inside an archive. The new
1534 implementation is significantly faster and can be wrapped in a

1536 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1625-----------------
1626
Georg Brandlba83f822010-03-14 09:50:54 +00001627- The ``__complex__()`` method is now looked up on the class of instances to
1628 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001629
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001630- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1631 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1632
Mark Dickinson1b34d252010-01-01 17:27:30 +00001633- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001634 DeprecationWarning when passed a float argument where an integer was expected.
1635 These functions and methods now raise TypeError instead. The majority of the
1636 effects of this change are in the extension modules, but some core functions
1637 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1638 and many unicode/str methods.

1649 used to drop the time part of the result.
1650
Georg Brandlba83f822010-03-14 09:50:54 +00001651- Issue #1811: Improve accuracy and cross-platform consistency for true division
1652 of integers: the result of a/b is now correctly rounded for ints a and b (at
1653 least on IEEE 754 platforms), and in particular does not depend on the
1654 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001656- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00001661 executables on OSX.
1662
Georg Brandlba83f822010-03-14 09:50:54 +00001663 These executables now work properly with the arch(1) command: ``arch -ppc
1664 python`` will start a universal binary version of python in PPC mode (unlike
1665 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001688 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

1822 decimal string that's guaranteed to round back to x under correct rounding
1823 (with round-half-to-even rounding mode). Previously it gave a string based on
1824 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1825 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1826 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001828- Issue #7117: On almost all platforms: float-to-string and string-to-float
1829 conversions within Python are now correctly rounded. Places these conversions
1830 occur include: str for floats and complex numbers; the float and complex
1831 constructors; old-style and new-style numeric formatting; serialization and
1832 deserialization of floats and complex numbers using marshal, pickle and json;
1833 parsing of float and imaginary literals in Python code; Decimal-to-float
1834 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001835
Georg Brandlba83f822010-03-14 09:50:54 +00001836 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1837 providing correctly-rounded strtod and dtoa C functions. This code is
1838 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1839 the C compiler. There may be a small number of platforms on which correct
1840 operation of this code cannot be guaranteed, so the code is not used: notably,
1841 this applies to platforms where the C double format is not IEEE 754 binary64,
1842 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1843 and Python's configure script is unable to determine how to change the FPU
1844 precision. On these platforms conversions use the platform strtod and dtoa,
1845 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001847- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1848 uses the correctly-rounded string <-> float conversions described above (when
1849 available), and so produces correctly rounded results that will display nicely
1850 under the float repr. There are two related small changes: (1) round now
1851 accepts any class with an ``__index__()`` method for its second argument (but
1852 no longer accepts floats for the second argument), and (2) an excessively
1853 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1854 raises an exception.

2204
Georg Brandlba83f822010-03-14 09:50:54 +00002205- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2206 file objects with closefd=False. The file descriptor is still kept open but
2207 the file object behaves like a closed file. The ``FileIO`` object also got a

2233 this code path is really executed because I cannot move to such directory on

2260 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

3437 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3438 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003637- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3639 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3640 ``printf`` function, whereas PyString_FromFormat has an independent

Nick Coghland2e09382008-09-11 12:11:06 +00003711- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003712 return a list or None rather than a custom object.
3713
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003714- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003738 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3739 for catch_warnings() also led to an improvement in the raising of a
3740 DeprecationWarning related to warnings.warn_explicit().
3741

3764
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003765- Issue #2975: When compiling several extension modules with Visual Studio 2008
3766 from the same python interpreter, some environment variables would grow
3767 without limit.
3768
Benjamin Peterson37346b22008-08-23 20:27:43 +00003769- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003806What's New in Python 2.6 beta 3?
3807================================
3808
Barry Warsaw07a4a382008-08-21 01:15:08 +00003809*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003810
3811Core and Builtins
3812-----------------
3813
Guido van Rossumf8402962008-08-20 15:01:50 +00003814- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3815 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3816 extensions do not automatically benefit from the class attribute
3817 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3818 to their tp_flags field if they care. This is a backwards
3819 compatibility feature; in 3.0, all types will use the cache by
3820 default.
3821
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003822- Keyword arguments can now follow starred arguments. (``f(a, *args,
3823 keyword=23)`` is now valid syntax.)
3824
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003825- ctypes function pointers that are COM methods have a boolean True
3826 value again.
3827
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003828- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3829 by denying s# to parse objects that have a releasebuffer procedure,
3830 and introducing s*.
3831
Georg Brandl1e13ea92008-08-11 09:07:59 +00003832- Issue #3537: Fix an assertion failure when an empty but presized dict
3833 object was stored in the freelist.
3834
Mark Dickinsonb6467572008-08-04 21:30:09 +00003835- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3836 ValueError consistently across platforms.
3837
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003838- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3839 (64bit Unix, for example), unichr() would truncate its argument and return
3840 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3841
Neal Norwitze7d8be82008-07-31 17:17:14 +00003842- Apply security patches from Apple.
3843
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003844- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3845 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3846
Antoine Pitrou92f82162008-07-25 22:22:08 +00003847- Issue #1819: function calls with several named parameters are now on
3848 average 35% faster (as measured by pybench).
3849
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003850- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3851 the python debugger steps into a class statement: the free variables (local
3852 variables defined in an outer scope) would be deleted from the outer scope.
3853
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003854- Issue #2620: Overflow checking when allocating or reallocating memory
3855 was not always being done properly in some python types and extension
3856 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3857 all been updated to perform better checks and places in the code that
3858 would previously leak memory on the error path when such an allocation
3859 failed have been fixed.

3862-------
3863
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003864- Issue #3612: Added some missing basic types in ctypes.wintypes.
3865
Benjamin Petersone977ad42008-08-20 01:42:01 +00003866- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3867 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3868
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003869- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3870 version reported by these tools does not necessarily follow the python
3871 version numbering scheme, so the module is less strict when parsing it.
3872
Nick Coghlanf70385a2008-08-18 12:42:46 +00003873- Issue #2235: Added Py3k warnings for types which will become unhashable
3874 under the stricter __hash__ inheritance rules in 3.0. Several types
3875 which did not meet the rules for hash invariants and were already
3876 unhashable in 3.0 have now been explicitly flagged as unhashable in
3877 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3878 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3879
Brett Cannon88f801d2008-08-18 00:46:22 +00003880- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3881 imported into the module but exposed as part of the module's API.
3882
Brett Cannon7b96f072008-08-18 00:41:11 +00003883- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3884
Brett Cannon46225e72008-08-18 00:36:52 +00003885- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003887- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3888
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003889- Issue #3575: Incremental decoder's decode function now takes bytearray
3890 by using 's*' instead of 't#'.
3891
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003892- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003893 fails unicode conversion on 2nd parameter. (windows only)
3894
Georg Brandl222e2082010-08-01 22:27:39 +00003895- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003896 in a redirect.
3897
Brett Cannonabe423e2008-08-16 21:47:07 +00003898- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003899 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003900
Facundo Batistaeb90b782008-08-16 14:44:07 +00003901- Issue #2776: fixed small issue when handling an URL with double slash
3902 after a 302 response in the case of not going through a proxy.
3903
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003904- Issue #2676: in the email package, content-type parsing was hanging on
3905 pathological input because of quadratic or exponential behaviour of a
3906 regular expression.
3907
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003908- Issue #3476: binary buffered reading through the new "io" library is now
3909 thread-safe.
3910
Brett Cannonbf3157b2008-08-14 05:00:03 +00003911- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3912 since mimetools itself is deprecated. Because modules are cached, all
3913 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3914
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003915- Issue #3134: shutil referenced undefined WindowsError symbol.
3916
Robert Schuppenies14646332008-08-10 11:01:53 +00003917- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3918 menu entries were not deleted.
3919
Brett Cannon83e81842008-08-09 23:30:55 +00003920- Copied the implementation of reduce() to _functools.reduce() to have a
3921 version that did not raise a DeprecationWarning under -3.
3922
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003923- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3924 a MemoryError rather than silently stop the iteration.
3925
Guido van Rossum59ce9012008-08-09 14:55:34 +00003926- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3927 to _sre.compile() will now be rejected. This should not affect anybody
3928 since the re.compile() function never generates invalid re-bytecode.
3929
Skip Montanaroa032bf42008-08-08 22:52:51 +00003930- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3931 upon first access it can be automatically initialized from the csv file if
3932 it wasn't initialized during instantiation.
3933
Brett Cannon3aa2a492008-08-06 22:28:09 +00003934- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3935 the reload() built-in has been removed.
3936
Brett Cannon7e30b672008-08-04 21:52:25 +00003937- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003938 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003939 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,

3941 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3942 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3943 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Antoine Pitroude781a42008-08-09 12:43:23 +00003949 asking for a specific length. This problem only affected files opened
3950 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003951
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003952- Issue #3449: Update decimal module to use most recent specification
3953 (v. 1.68) and tests (v. 2.58) from IBM.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004000What's New in Python 2.6 beta 2?
4001================================
4002
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004003*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004005Core and Builtins
4006-----------------
4007
Georg Brandl3e483f62008-07-16 22:57:41 +00004008- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4009 its methods now allow for items objects that can be converted to
4010 an integer using operator.index().
4011
Mark Dickinson64b7e502008-07-16 09:40:03 +00004012- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4013 produced a ValueError instead of giving the correct float.
4014
Eric Smitha5fa5a22008-07-16 00:11:49 +00004015- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4016 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4017
Mark Dickinson7103aa42008-07-15 19:08:33 +00004018- Issue #3008: the float type has a new instance method 'float.hex'
4019 and a new class method 'float.fromhex' to convert floating-point
4020 numbers to and from hexadecimal strings, respectively.
4021
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004022- Issue #2235: __hash__ is once again inherited by default. To allow
4023 collections.Hashable to remain meaningful in the presence of the
4024 default hash implementation (object.__hash__), it is now possible
4025 to explicit block inheritance of hash by setting __hash__=None at
4026 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4027 level.
4028
Nick Coghlanb028f502008-07-13 14:52:36 +00004029- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4030 the parent module cannot be found while performing an absolute import.
4031 This means that an incorrectly defined __package__ attribute will
4032 now only prevent relative imports in that module rather than causing
4033 all imports from that module to fail.
4034
Nick Coghlan14ff9942008-07-08 14:21:42 +00004035- Issue #2517: Allow unicode messages in Exceptions again by correctly
4036 bypassing the instance dictionary when looking up __unicode__ on
4037 new-style classes.
4038
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004039- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4040 set to a custom object whose write() method happens to install
4041 another file in sys.stdout.
4042
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004043- Issue #3088: Corrected a race condition in classes derived from
4044 threading.local: the first member set by a thread could be saved in
4045 another thread's dictionary.
4046
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004047- Issue #3004: Minor change to slice.indices(): the start and stop
4048 arguments are now treated identically, making the behaviour easier
4049 to describe and understand. For example, slice(None, -10,
4050 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4051 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4052 10, -1).
4053
Georg Brandl278fc502008-07-19 12:46:12 +00004054- Issue #3219: Calling a function with repeated keyword arguments,
4055 f(a=2, a=23), would not cause a syntax error. This was a regression
4056 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004057
Georg Brandl278fc502008-07-19 12:46:12 +00004058- Issue #2862: Make int and float freelist management consistent with
4059 other freelists. Changes their CompactFreeList apis into
4060 ClearFreeList apis and calls them via gc.collect().

4064
Thomas Heller57adf222008-08-14 19:10:48 +00004065- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4066 api functions without holding the GIL, which could lead to a fatal
4067 error when they failed.
4068
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004069- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004093
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004094- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4095 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004096 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004097 content-length. The problem had been corrected in the 2.4 branch, but never
4098 merged into trunk.
4099
Georg Brandle78fbcc2008-07-05 10:13:36 +00004100- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004113- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4114 handling is now the same as that of other special attributes like __name__).
4115
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004116- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00004568- Issue #1631171: Re-implement the 'warnings' module in C (the
4569 original Python code has been kept as backup). This will allow for
4570 using the 'warning's machinery in such places as the parser where
4571 use of pure Python code is not possible. Both the ``showarning()``
4572 and ``formatwarning()`` gain an optional 'line' argument which is
4573 not called by default for backwards-compatibility reasons. Setting
4574 ``warnings.showwarning()`` to an implementation that lacks support
4575 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004617- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004618 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004638- Issue #2550: The approach used by client/server code for obtaining
4639 ports to listen on in network-oriented tests has been refined in an
4640 effort to facilitate running multiple instances of the entire
4641 regression test suite in parallel without issue.
4642 test_support.bind_port() has been fixed such that it will always
4643 return a unique port -- which wasn't always the case with the
4644 previous implementation, especially if socket options had been set
4645 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4646 new implementation of bind_port() will actually raise an exception
4647 if it is passed an AF_INET/SOCK_STREAM socket with either the
4648 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4649 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4650 the socket it's been passed. This currently only applies to
4651 Windows. This option prevents any other sockets from binding to the
4652 host/port we've bound to, thus removing the possibility of the
4653 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4654 when a second SOCK_STREAM socket binds and accepts to a host/port
4655 that's already been bound by another socket. The optional preferred
4656 port parameter to bind_port() has been removed. Under no
4657 circumstances should tests be hard coding ports!
4658
4659 test_support.find_unused_port() has also been introduced, which will
4660 pass a temporary socket object to bind_port() in order to obtain an
4661 unused port. The temporary socket object is then closed and
4662 deleted, and the port is returned. This method should only be used
4663 for obtaining an unused port in order to pass to an external program
4664 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4665 a parameter to a server-oriented class that doesn't give you direct
4666 access to the underlying socket used.
4667
4668 Finally, test_support.HOST has been introduced, which should be used
4669 for the host argument of any relevant socket calls (i.e. bind and
4670 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004671
4672 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004673 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004674 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4675 test_asynchat and test_socket_ssl.
4676
Georg Brandl3ee81df2008-05-17 18:14:43 +00004677 It is now possible for multiple instances of the regression test
4678 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004957- Added the future_builtins module, which contains hex() and oct().
4958 These are the PEP 3127 version of these functions, designed to be
4959 compatible with the hex() and oct() builtins from Python 3.0. They
4960 differ slightly in their output formats from the existing, unchanged
4961 Python 2.6 builtins. The expected usage of the future_builtins
4962 module is:
4963 from future_builtins import hex, oct
4964
Eric Smith7ef40bf2008-02-20 23:34:22 +00004965- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4966 exponents for exponents with absolute value < 100. Follows C99
4967 standard. This is a change on Windows, which would use 3 digits.
4968 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4969 so that any alterations it does to the resulting string will be
4970 available in stringlib/formatter.h (for float.__format__).
4971
Eric Smith5a3c1352008-02-19 13:21:56 +00004972- Implemented PEP 3101, Advanced String Formatting. This adds a new
4973 builtin format(); a format() method for str and unicode; a
4974 __format__() method to object, str, unicode, int, long, float, and
4975 datetime; the class string.Formatter; and the C API
4976 PyObject_Format().
4977
Georg Brandl3ee81df2008-05-17 18:14:43 +00004978- Fixed several potential crashes, all caused by specially crafted
4979 __del__ methods exploiting objects in temporarily inconsistent
4980 state.

5006
Georg Brandl3ee81df2008-05-17 18:14:43 +00005007- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5008 calls. Python expected the return type int but the fork familie
5009 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005023- Patch #1473257: generator objects gain a gi_code attribute. This is
5024 the same object as the func_code attribute of the function that
5025 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005026
Georg Brandl3ee81df2008-05-17 18:14:43 +00005027- Issue #1920: "while 0" statements were completely removed by the
5028 compiler, even in the presence of an "else" clause, which is
5029 supposed to be run when the condition is false. Now the compiler
5030 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005031

Christian Heimes082c9b02008-01-23 14:20:50 +00005041 several extension methods and modules do not work without unicode
5042 support.
5043
Georg Brandl26543b12008-01-21 18:36:51 +00005044- Issue #1882: when compiling code from a string, encoding cookies in the
5045 second line of code were not always recognized correctly.
5046
Georg Brandl14404b62008-01-19 19:27:05 +00005047- Issue #1679: "0x" was taken as a valid integer literal.
5048
Georg Brandl6caad7d2008-01-26 14:19:22 +00005049- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005050 added.
5051
Christian Heimesc94e2b52008-01-14 04:13:37 +00005052- sys.float_info / PyFloat_GetInfo: The floating point information
5053 object was converted from a dict to a specialized structseq object.
5054
Georg Brandl3ee81df2008-05-17 18:14:43 +00005055- Patch #1816: Added sys.flags structseq. It exposes the status of
5056 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005057
Georg Brandl3ee81df2008-05-17 18:14:43 +00005058- Objects/structseq.c: Implemented new structseq representation. The
5059 patch makes structseqs (e.g. the return value of os.stat) more
5060 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005061
Georg Brandl3ee81df2008-05-17 18:14:43 +00005062- Patch #1700288: added a type attribute cache that caches method
5063 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005064
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005065- Bug #1776: __import__() no longer accepts filenames on any platform.
5066 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005067
Georg Brandlaed6c662008-01-07 17:25:53 +00005068- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5069
Georg Brandl3ee81df2008-05-17 18:14:43 +00005070- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5071 envvar and sys.dont_write_bytecode attribute. All these can be set
5072 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005073
Georg Brandl3ee81df2008-05-17 18:14:43 +00005074- Improve some exception messages when Windows fails to load an
5075 extension module. Now we get for example '%1 is not a valid Win32
5076 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005077
Georg Brandl3ee81df2008-05-17 18:14:43 +00005078- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005080- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5081 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005082
Christian Heimes0a8143f2007-12-18 23:22:54 +00005083- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005084 and INF. float("nan"), float("inf") and float("-inf") now work on
5085 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005086
Georg Brandl3ee81df2008-05-17 18:14:43 +00005087- Compiler now generates simpler and faster code for dictionary
5088 literals. The oparg for BUILD_MAP now indicates an estimated
5089 dictionary size. There is a new opcode, STORE_MAP, for adding
5090 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005100- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005101 SystemError.
5102
Nick Coghlanef01d822007-12-03 12:55:17 +00005103- PEP 366: Allow explicit relative imports when executing modules
5104 inside packages with the -m switch via a new module level
5105 __package__ attribute.
5106

5108 running, and if the deallocation of its frames somehow calls the
5109 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005110

Georg Brandl3ee81df2008-05-17 18:14:43 +00005119- Patch #1739468: Directories and zipfiles containing a __main__.py
5120 file can now be directly executed by passing their name to the
5121 interpreter. The directory/zipfile is automatically inserted as the
5122 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005123
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- Issue #1265: Fix a problem with sys.settrace, if the tracing
5125 function uses a generator expression when at the same time the
5126 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005127
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005128- sets and frozensets now have an isdisjoint() method.
5129
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005130- optimize the performance of builtin.sum().
5131
Neal Norwitz44f326e2007-10-05 05:29:17 +00005132- Fix warnings found by the new version of the Coverity checker.
5133
Georg Brandl21e99f42010-03-07 15:23:59 +00005134- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005135 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5136 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005137
Georg Brandl3ee81df2008-05-17 18:14:43 +00005138- Issue #1686386: Tuple's tp_repr did not take into account the
5139 possibility of having a self-referential tuple, which is possible
5140 from C code. Nor did object's tp_str consider that a type's tp_str
5141 could do something that could lead to an inifinite recursion.
5142 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5143 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005144
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145- Issue #1164: It was possible to trigger deadlock when using the
5146 'print' statement to write to a file since the GIL was not released
5147 as needed. Now PyObject_Print() does the right thing along with
5148 various tp_print implementations of the built-in types and those in
5149 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005150
Georg Brandl3ee81df2008-05-17 18:14:43 +00005151- Issue #1147: Exceptions were directly allowing string exceptions in
5152 their throw() method even though string exceptions no longer
5153 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005154
Georg Brandl3ee81df2008-05-17 18:14:43 +00005155- Issue #1096: Prevent a segfault from getting the repr of a very
5156 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005157
Brett Cannon1e534b52007-09-07 04:18:30 +00005158- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005159 PyObject_Call() never calling back out to Python code to trigger
5160 recursion depth updates/checks. Required the creation of a static
5161 RuntimeError instance in case normalizing an exception put the
5162 recursion check value past its limit. Fixes crashers
5163 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005164
Georg Brandl3ee81df2008-05-17 18:14:43 +00005165- Patch #1031213: Decode source line in SyntaxErrors back to its

5169 with %G.
5170
Georg Brandl3ee81df2008-05-17 18:14:43 +00005171- Prevent expandtabs() on string and unicode objects from causing a
5172 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00005173

Neal Norwitz0ac60192007-05-27 04:08:54 +00005178- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005179 __*__ attributes. (Some already existed, e.g., __doc__ and
5180 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005181
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005182- Add -3 option to the interpreter to warn about features that are
5183 deprecated and will be changed/removed in Python 3.0.
5184
Georg Brandl2134e752007-05-21 20:34:16 +00005185- Patch #1686487: you can now pass any mapping after '**' in function
5186 calls.
5187
Collin Winter62903052007-05-18 23:11:24 +00005188- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005189 "except E as target:". This is to provide forwards compatibility
5190 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005191
Brett Cannon229cee22007-05-05 01:34:02 +00005192- Deprecate BaseException.message as per PEP 352.
5193
Georg Brandl3ee81df2008-05-17 18:14:43 +00005194- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005195 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005196
Vinay Sajip8549ce32007-05-06 17:53:37 +00005197- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005198 setting a plain string, ie don't expand to single letter identifiers.
5199
Raymond Hettinger13936692007-04-11 18:40:58 +00005200- Request #1191699: Slices can now be pickled.
5201
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005202- Request #1193128: str.translate() now allows a None argument for
5203 translations that only remove characters without re-mapping the
5204 remaining characters.
5205
Georg Brandl5cb76c12007-03-21 09:00:39 +00005206- Patch #1682205: a TypeError while unpacking an iterable is no longer
5207 masked by a generic one with the message "unpack non-sequence".
5208
Neal Norwitzaa754b72007-03-21 06:39:48 +00005209- Remove unused file Python/fmod.c.
5210
Guido van Rossum143b5642007-03-23 04:58:42 +00005211- Bug #1683368: The object.__init__() and object.__new__() methods are
5212 now stricter in rejecting excess arguments. The only time when
5213 either allows excess arguments is when it is not overridden and the
5214 other one is. For backwards compatibility, when both are
5215 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005216 warning later). Also, type.__init__() insists on the same signature
5217 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005218
Georg Brandl3ee81df2008-05-17 18:14:43 +00005219- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5220 object to complex using its __complex__() method before falling back
5221 to the __float__() method. Therefore, the functions in the cmath
5222 module now can operate on objects that define a __complex__()
5223 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005224
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225- Patch #1623563: allow __class__ assignment for classes with
5226 __slots__. The old and the new class are still required to have the
5227 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005228
Georg Brandl3ee81df2008-05-17 18:14:43 +00005229- Patch #1642547: Fix an error/crash when encountering syntax errors
5230 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005232- Patch #1462488: Python no longer segfaults when
5233 ``object.__reduce_ex__()`` is called with an object that is faking
5234 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005235
Georg Brandl3ee81df2008-05-17 18:14:43 +00005236- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00005239- Patch #1444529: the builtin compile() now accepts keyword arguments.
5240
Georg Brandl7b9c5552007-03-12 14:30:05 +00005241- Bug #1678647: write a newline after printing an exception in any
5242 case, even when converting the value to a string failed.
5243
Georg Brandl871f1bc2007-03-12 13:17:36 +00005244- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005245 its argument, if it exists. If not, it will work like before. This
5246 allows customizing the output of dir() in the presence of a
5247 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005248
Collin Winter276887b2007-03-12 16:11:39 +00005249- Patch #922167: Python no longer segfaults when faced with infinitely
5250 self-recursive reload() calls (as reported by bug #742342).
5251
Georg Brandl3ee81df2008-05-17 18:14:43 +00005252- Patch #1675981: remove unreachable code from ``type.__new__()``
5253 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005255- Patch #1491866: change the complex() constructor to allow
5256 parthensized forms. This means complex(repr(x)) now works instead of
5257 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005258
Georg Brandlaa2321b2007-03-07 00:40:28 +00005259- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005260 makes the filenames the warning module prints much more sensible
5261 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005262
Georg Brandl49aafc92007-03-07 00:34:46 +00005263- Variant of patch #697613: don't exit the interpreter on a SystemExit
5264 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005265 variable is given, but break into the interactive interpreter just
5266 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005271- Bug #1674503: close the file opened by execfile() in an error
5272 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005273
Georg Brandl0fca97a2007-03-05 22:28:08 +00005274- Patch #1674228: when assigning a slice (old-style), check for the
5275 sq_ass_slice instead of the sq_slice slot.
5276
Georg Brandl3ee81df2008-05-17 18:14:43 +00005277- When printing an unraisable error, don't print exceptions. before
5278 the name. This duplicates the behavior whening normally printing

Facundo Batistad918a652007-04-24 13:54:38 +00005770- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005771 the client's request was successfully received, understood, and
5772 accepted. Now in these cases no error is raised in urllib (issue
5773 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005781- Added a timeout parameter to the constructor of other protocols
5782 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5783 work started with create_connection() and timeout in httplib, and
5784 closes patch #723312.
5785
Vinay Sajip8549ce32007-05-06 17:53:37 +00005786- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00005812 AttributeError instead of an IOError when the server's response
5813 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005814

Georg Brandl3ee81df2008-05-17 18:14:43 +00005819- Patch #1429539: pdb now correctly initializes the __main__ module
5820 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005821 correctly now.
5822

Georg Brandl3ee81df2008-05-17 18:14:43 +00005830- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00005843- Patch #1581073: add a flag to textwrap that prevents the dropping of
5844 whitespace while wrapping.
5845
Georg Brandl92a6bae2007-03-13 17:43:32 +00005846- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005847 are set for invalid interpolation sequences that would lead to
5848 errors on reading back those values.

5891 returned string up to the first NUL character.
5892

5902
Georg Brandl3ee81df2008-05-17 18:14:43 +00005903- unittest now verifies more of its assumptions. In particular,
5904 TestCase and TestSuite subclasses (not instances) are no longer
5905 accepted in TestSuite.addTest(). This should cause no
5906 incompatibility since it never made sense with ordinary subclasses
5907 -- the failure just occurred later, with a more cumbersome
5908 exception.

5917 given a unicode argument and os.listdir() returns unicode filenames.
5918
Georg Brandl3ee81df2008-05-17 18:14:43 +00005919- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006297 time so that opening a database previously created with the DB_DUP
6298 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6299 opens. Specifically: dictionary assignment to a DB object will
6300 replace all values for a given key when the database allows
6301 duplicate values. DB users should use DB.put(k, v) when they want
6302 to store duplicates; not DB[k] = v.

6309 characters with ASCII value less than 32. Also, it correctly quotes
6310 dots only if they occur on a single line, as opposed to the previous
6311 behavior of quoting dots if they are the second character of any
6312 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006690- Added case insensitive comparison methods ``PyOS_stricmp(char*,
