Ned Deily0d0ea482012-02-10 12:59:06 +0100594- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
595 Distutils-based packages with C extension modules may fail because
596 Apple has removed gcc-4.2, the version used to build python.org
597 64-bit/32-bit Pythons. If the user does not explicitly override
598 the default C compiler by setting the CC environment variable,
599 Distutils will now attempt to compile extension modules with clang
600 if gcc-4.2 is required but not found. Also as a convenience, if
601 the user does explicitly set CC, substitute its value as the default
602 compiler in the Distutils LDSHARED configuration variable for OS X.
603 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
604 SDK, neither of which are available in Xcode 4. This change does not
605 attempt to override settings to support their use with Xcode 4.)

881 and was unreliable since tests or user programs could modify the interpreter
882 environment after Distutils set it. Instead, have Distutils set the the
883 deployment target only in the environment of each build subprocess. It is

1861 by Andrew Bennetts.

1870
Raymond Hettinger20397532010-09-12 02:11:45 +00001871- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1872 This prevents user-created self-referencing ordered dictionaries from
1873 becoming permanently uncollectable GC garbage. The downside is that
1874 removing __del__ means that the internal doubly-linked list has to wait for
1875 GC collection rather than freeing memory immediately when the refcnt drops
1876 to zero.
1877
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001878- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1881
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001882- Issue #9792: In case of connection failure, socket.create_connection()
1883 would swallow the exception and raise a new one, making it impossible
1884 to fetch the original errno, or to filter timeout errors. Now the
1885 original error is re-raised.
1886
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001887- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
1888 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
1889 be updated back after the system call. Original patch by Brian Brazil.

1895 ConfigParser.write.
1896
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00001897- Issue #808164: Fixed socket.close to avoid references to globals, to
1898 avoid issues when socket.close is called from a __del__ method.

1905 falling into recursion.
1906
R. David Murray7c4bf552010-08-25 01:45:57 +00001907- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1908 character years even if the message contains RFC822 two character years.
1909
Daniel Stutzbach91287322010-08-24 21:09:30 +00001910- Issue #8750: Fixed MutableSet's methods to correctly handle

1922 module now correctly return a set. (Patch by Eli Bendersky.)
1923
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001924- Issue #9617: Signals received during a low-level write operation aren't
1925 ignored by the buffered IO layer anymore.
1926
Benjamin Peterson52c36052010-08-21 03:03:22 +00001927- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
1928 are not held onto after they are deleted elsewhere.
1929
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001930- Issue #9626: the view methods for collections.OrderedDict() were returning
1931 the unordered versions inherited from dict. Those methods are now
1932 overridden to provide ordered views.
1933
Éric Araujo0389ae62010-08-14 03:07:46 +00001934- Issue #8688: MANIFEST files created by distutils now include a magic
1935 comment indicating they are generated. Manually maintained MANIFESTs
1936 without this marker will not be overwritten or removed.
1937
Antoine Pitroue1436d12010-08-12 15:25:51 +00001938- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
1939 and a BadZipfile error is raised if it doesn't match (as used to be the
1940 case in Python 2.5 and earlier).
1941
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001942- Issue #9550: a BufferedReader could issue an additional read when the
1943 original read request had been satisfied, which could block indefinitely
1944 when the underlying raw IO channel was e.g. a socket. Report and original
1945 patch by Jason V. Miller.
1946
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001947- Issue #9551: Don't raise TypeError when setting the value to None for

1966 This is how it is supposed to work, wget and curl do the same. Previous
1967 behavior was wrong.

1975 the option character for the added 'h/help' option if prefix_chars
1976 does not contain a '-', instead of raising an error.
1977

2339 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2340 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2341 Previous versions returned a single u'\ufffd'.

2351 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00002595- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
2596 the method could block indefinitely if called just before the event loop

Antoine Pitroufc69af12010-04-24 20:04:58 +00002600- Issue #5103: SSL handshake would ignore the socket timeout and block
2601 indefinitely if the other end didn't respond.
2602
Georg Brandlfee0f442010-05-22 21:26:21 +00002603- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002696 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002721- Issue #7301: Add environment variable $PYTHONWARNINGS.
2722
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002723- Issue #8329: Don't return the same lists from select.select when no fds are
2724 changed.
2725
Georg Brandlfee0f442010-05-22 21:26:21 +00002726- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002727 on 64-bit machines. The shift count for either left or right shift is
2728 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00002736- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2737 with a non-empty format string. This is an effort to future-proof user
2738 code. If a derived class does not currently implement __format__ but later
2739 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002740 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002741 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002774- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00002791- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2792 InvalidOperation instead of returning False. (Comparisons involving a quiet
2793 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2794 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002795
Georg Brandlfee0f442010-05-22 21:26:21 +00002796- Issue #2531: Comparison operations between floats and Decimal instances now
2797 return a result based on the numeric values of the operands; previously they
2798 returned an arbitrary result based on the relative ordering of id(float) and
2799 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00002813- Comparisons using one of <, <=, >, >= between a complex instance and a
2814 Fractions instance now raise TypeError instead of returning True/False. This
2815 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2816 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003234 file position when calling `truncate()`. It would previously change the file
3235 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003236 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3239 class used to represent files stored inside an archive. The new
3240 implementation is significantly faster and can be wrapped in a

3242 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3331-----------------
3332
Georg Brandlba83f822010-03-14 09:50:54 +00003333- The ``__complex__()`` method is now looked up on the class of instances to
3334 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003335
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003336- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

3338
Mark Dickinson1b34d252010-01-01 17:27:30 +00003339- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003340 DeprecationWarning when passed a float argument where an integer was expected.
3341 These functions and methods now raise TypeError instead. The majority of the
3342 effects of this change are in the extension modules, but some core functions
3343 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3344 and many unicode/str methods.

3355 used to drop the time part of the result.
3356
Georg Brandlba83f822010-03-14 09:50:54 +00003357- Issue #1811: Improve accuracy and cross-platform consistency for true division
3358 of integers: the result of a/b is now correctly rounded for ints a and b (at
3359 least on IEEE 754 platforms), and in particular does not depend on the
3360 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003362- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00003367 executables on OSX.
3368
Georg Brandlba83f822010-03-14 09:50:54 +00003369 These executables now work properly with the arch(1) command: ``arch -ppc
3370 python`` will start a universal binary version of python in PPC mode (unlike
3371 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00003394 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00003534- Issue #7117: On almost all platforms: float-to-string and string-to-float
3535 conversions within Python are now correctly rounded. Places these conversions
3536 occur include: str for floats and complex numbers; the float and complex
3537 constructors; old-style and new-style numeric formatting; serialization and
3538 deserialization of floats and complex numbers using marshal, pickle and json;
3539 parsing of float and imaginary literals in Python code; Decimal-to-float
3540 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003541
Georg Brandlba83f822010-03-14 09:50:54 +00003542 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3543 providing correctly-rounded strtod and dtoa C functions. This code is
3544 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3545 the C compiler. There may be a small number of platforms on which correct
3546 operation of this code cannot be guaranteed, so the code is not used: notably,
3547 this applies to platforms where the C double format is not IEEE 754 binary64,
3548 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3549 and Python's configure script is unable to determine how to change the FPU
3550 precision. On these platforms conversions use the platform strtod and dtoa,
3551 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003553- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3554 uses the correctly-rounded string <-> float conversions described above (when
3555 available), and so produces correctly rounded results that will display nicely
3556 under the float repr. There are two related small changes: (1) round now
3557 accepts any class with an ``__index__()`` method for its second argument (but
3558 no longer accepts floats for the second argument), and (2) an excessively
3559 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3560 raises an exception.

5142 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5143 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5144 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005343- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5344 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5345 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5346 ``printf`` function, whereas PyString_FromFormat has an independent
5347 implementation and uses "%zd" on all platforms for size_t values.
5348 This makes a difference on win64, where ``printf`` needs "%Id" to display
5349 64bit values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005444 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5445 for catch_warnings() also led to an improvement in the raising of a
5446 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005512What's New in Python 2.6 beta 3?
5513================================
5514
Barry Warsaw07a4a382008-08-21 01:15:08 +00005515*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005516
5517Core and Builtins
5518-----------------
5519
Guido van Rossumf8402962008-08-20 15:01:50 +00005520- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5521 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5522 extensions do not automatically benefit from the class attribute
5523 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5524 to their tp_flags field if they care. This is a backwards
5525 compatibility feature; in 3.0, all types will use the cache by
5526 default.
5527
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005528- Keyword arguments can now follow starred arguments. (``f(a, *args,
5529 keyword=23)`` is now valid syntax.)
5530
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005531- ctypes function pointers that are COM methods have a boolean True
5532 value again.
5533
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005534- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5535 by denying s# to parse objects that have a releasebuffer procedure,
5536 and introducing s*.
5537
Georg Brandl1e13ea92008-08-11 09:07:59 +00005538- Issue #3537: Fix an assertion failure when an empty but presized dict
5539 object was stored in the freelist.
5540
Mark Dickinsonb6467572008-08-04 21:30:09 +00005541- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5542 ValueError consistently across platforms.
5543
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005544- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5545 (64bit Unix, for example), unichr() would truncate its argument and return
5546 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5547
Neal Norwitze7d8be82008-07-31 17:17:14 +00005548- Apply security patches from Apple.
5549
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005550- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5551 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5552
Antoine Pitrou92f82162008-07-25 22:22:08 +00005553- Issue #1819: function calls with several named parameters are now on
5554 average 35% faster (as measured by pybench).
5555
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005556- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5557 the python debugger steps into a class statement: the free variables (local
5558 variables defined in an outer scope) would be deleted from the outer scope.
5559
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005560- Issue #2620: Overflow checking when allocating or reallocating memory
5561 was not always being done properly in some python types and extension
5562 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5563 all been updated to perform better checks and places in the code that
5564 would previously leak memory on the error path when such an allocation
5565 failed have been fixed.

5568-------
5569
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005570- Issue #3612: Added some missing basic types in ctypes.wintypes.
5571
Benjamin Petersone977ad42008-08-20 01:42:01 +00005572- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5573 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5574
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005575- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5576 version reported by these tools does not necessarily follow the python
5577 version numbering scheme, so the module is less strict when parsing it.
5578
Nick Coghlanf70385a2008-08-18 12:42:46 +00005579- Issue #2235: Added Py3k warnings for types which will become unhashable
5580 under the stricter __hash__ inheritance rules in 3.0. Several types
5581 which did not meet the rules for hash invariants and were already
5582 unhashable in 3.0 have now been explicitly flagged as unhashable in
5583 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5584 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5585
Brett Cannon88f801d2008-08-18 00:46:22 +00005586- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5587 imported into the module but exposed as part of the module's API.
5588
Brett Cannon7b96f072008-08-18 00:41:11 +00005589- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5590
Brett Cannon46225e72008-08-18 00:36:52 +00005591- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005593- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5594
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005595- Issue #3575: Incremental decoder's decode function now takes bytearray
5596 by using 's*' instead of 't#'.
5597
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005598- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005599 fails unicode conversion on 2nd parameter. (windows only)
5600
Georg Brandl222e2082010-08-01 22:27:39 +00005601- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005602 in a redirect.
5603
Brett Cannonabe423e2008-08-16 21:47:07 +00005604- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005605 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005606
Facundo Batistaeb90b782008-08-16 14:44:07 +00005607- Issue #2776: fixed small issue when handling an URL with double slash
5608 after a 302 response in the case of not going through a proxy.
5609
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005610- Issue #2676: in the email package, content-type parsing was hanging on
5611 pathological input because of quadratic or exponential behaviour of a
5612 regular expression.
5613
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005614- Issue #3476: binary buffered reading through the new "io" library is now
5615 thread-safe.
5616
Brett Cannonbf3157b2008-08-14 05:00:03 +00005617- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5618 since mimetools itself is deprecated. Because modules are cached, all
5619 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5620
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005621- Issue #3134: shutil referenced undefined WindowsError symbol.
5622
Robert Schuppenies14646332008-08-10 11:01:53 +00005623- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5624 menu entries were not deleted.
5625
Brett Cannon83e81842008-08-09 23:30:55 +00005626- Copied the implementation of reduce() to _functools.reduce() to have a
5627 version that did not raise a DeprecationWarning under -3.
5628
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005629- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5630 a MemoryError rather than silently stop the iteration.
5631
Guido van Rossum59ce9012008-08-09 14:55:34 +00005632- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5633 to _sre.compile() will now be rejected. This should not affect anybody
5634 since the re.compile() function never generates invalid re-bytecode.
5635
Skip Montanaroa032bf42008-08-08 22:52:51 +00005636- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5637 upon first access it can be automatically initialized from the csv file if
5638 it wasn't initialized during instantiation.
5639
Brett Cannon3aa2a492008-08-06 22:28:09 +00005640- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5641 the reload() built-in has been removed.
5642
Brett Cannon7e30b672008-08-04 21:52:25 +00005643- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005644 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005655 asking for a specific length. This problem only affected files opened
5656 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005657

5684
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005685- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

5699
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005700- Issue #643841: The language reference now provides more detailed
5701 coverage of the lookup process for special methods. The disclaimers
5702 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005706What's New in Python 2.6 beta 2?
5707================================
5708
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005709*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005711Core and Builtins
5712-----------------
5713
Georg Brandl3e483f62008-07-16 22:57:41 +00005714- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5715 its methods now allow for items objects that can be converted to
5716 an integer using operator.index().
5717
Mark Dickinson64b7e502008-07-16 09:40:03 +00005718- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5719 produced a ValueError instead of giving the correct float.
5720
Eric Smitha5fa5a22008-07-16 00:11:49 +00005721- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5722 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5723
Mark Dickinson7103aa42008-07-15 19:08:33 +00005724- Issue #3008: the float type has a new instance method 'float.hex'
5725 and a new class method 'float.fromhex' to convert floating-point
5726 numbers to and from hexadecimal strings, respectively.
5727
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005728- Issue #2235: __hash__ is once again inherited by default. To allow
5729 collections.Hashable to remain meaningful in the presence of the
5730 default hash implementation (object.__hash__), it is now possible
5731 to explicit block inheritance of hash by setting __hash__=None at
5732 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5733 level.
5734
Nick Coghlanb028f502008-07-13 14:52:36 +00005735- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5736 the parent module cannot be found while performing an absolute import.
5737 This means that an incorrectly defined __package__ attribute will
5738 now only prevent relative imports in that module rather than causing
5739 all imports from that module to fail.
5740
Nick Coghlan14ff9942008-07-08 14:21:42 +00005741- Issue #2517: Allow unicode messages in Exceptions again by correctly
5742 bypassing the instance dictionary when looking up __unicode__ on
5743 new-style classes.
5744
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005745- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5746 set to a custom object whose write() method happens to install
5747 another file in sys.stdout.
5748
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005749- Issue #3088: Corrected a race condition in classes derived from
5750 threading.local: the first member set by a thread could be saved in
5751 another thread's dictionary.
5752
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005753- Issue #3004: Minor change to slice.indices(): the start and stop
5754 arguments are now treated identically, making the behaviour easier
5755 to describe and understand. For example, slice(None, -10,
5756 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5757 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5758 10, -1).
5759
Georg Brandl278fc502008-07-19 12:46:12 +00005760- Issue #3219: Calling a function with repeated keyword arguments,
5761 f(a=2, a=23), would not cause a syntax error. This was a regression
5762 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005763
Georg Brandl278fc502008-07-19 12:46:12 +00005764- Issue #2862: Make int and float freelist management consistent with
5765 other freelists. Changes their CompactFreeList apis into
5766 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00005771- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5772 api functions without holding the GIL, which could lead to a fatal
5773 error when they failed.
5774
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005775- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5784 ForkingPickler.register() to resolve conflict with ctypes.
5785
Vinay Sajip51e65192008-07-18 09:01:10 +00005786- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005787
Thomas Heller880f5292008-07-15 19:39:38 +00005788- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5789 a valid dlerror() message.

Thomas Heller2bad6572008-07-15 17:19:50 +00005791- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5792 incomplete structure was created.

5797
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005798- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005799
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005800- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5801 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005802 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005803 content-length. The problem had been corrected in the 2.4 branch, but never
5804 merged into trunk.
5805
Georg Brandle78fbcc2008-07-05 10:13:36 +00005806- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005819- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5820 handling is now the same as that of other special attributes like __name__).
5821
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005822- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6278 and ``formatwarning()`` gain an optional 'line' argument which is
6279 not called by default for backwards-compatibility reasons. Setting
6280 ``warnings.showwarning()`` to an implementation that lacks support
6281 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006344- Issue #2550: The approach used by client/server code for obtaining
6345 ports to listen on in network-oriented tests has been refined in an
6346 effort to facilitate running multiple instances of the entire
6347 regression test suite in parallel without issue.
6348 test_support.bind_port() has been fixed such that it will always
6349 return a unique port -- which wasn't always the case with the
6350 previous implementation, especially if socket options had been set
6351 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6352 new implementation of bind_port() will actually raise an exception
6353 if it is passed an AF_INET/SOCK_STREAM socket with either the
6354 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6355 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6356 the socket it's been passed. This currently only applies to
6357 Windows. This option prevents any other sockets from binding to the
6358 host/port we've bound to, thus removing the possibility of the
6359 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6360 when a second SOCK_STREAM socket binds and accepts to a host/port
6361 that's already been bound by another socket. The optional preferred
6362 port parameter to bind_port() has been removed. Under no
6363 circumstances should tests be hard coding ports!
6364
6365 test_support.find_unused_port() has also been introduced, which will
6366 pass a temporary socket object to bind_port() in order to obtain an
6367 unused port. The temporary socket object is then closed and
6368 deleted, and the port is returned. This method should only be used
6369 for obtaining an unused port in order to pass to an external program
6370 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6371 a parameter to a server-oriented class that doesn't give you direct
6372 access to the underlying socket used.
6373
6374 Finally, test_support.HOST has been introduced, which should be used
6375 for the host argument of any relevant socket calls (i.e. bind and
6376 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006377
6378 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006379 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006380 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6381 test_asynchat and test_socket_ssl.
6382
Georg Brandl3ee81df2008-05-17 18:14:43 +00006383 It is now possible for multiple instances of the regression test
6384 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006663- Added the future_builtins module, which contains hex() and oct().
6664 These are the PEP 3127 version of these functions, designed to be
6665 compatible with the hex() and oct() builtins from Python 3.0. They
6666 differ slightly in their output formats from the existing, unchanged
6667 Python 2.6 builtins. The expected usage of the future_builtins
6668 module is:
6669 from future_builtins import hex, oct
6670
Eric Smith7ef40bf2008-02-20 23:34:22 +00006671- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6672 exponents for exponents with absolute value < 100. Follows C99
6673 standard. This is a change on Windows, which would use 3 digits.
6674 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6675 so that any alterations it does to the resulting string will be
6676 available in stringlib/formatter.h (for float.__format__).
6677
Eric Smith5a3c1352008-02-19 13:21:56 +00006678- Implemented PEP 3101, Advanced String Formatting. This adds a new
6679 builtin format(); a format() method for str and unicode; a
6680 __format__() method to object, str, unicode, int, long, float, and
6681 datetime; the class string.Formatter; and the C API
6682 PyObject_Format().
6683
Georg Brandl3ee81df2008-05-17 18:14:43 +00006684- Fixed several potential crashes, all caused by specially crafted
6685 __del__ methods exploiting objects in temporarily inconsistent
6686 state.

6697 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006698

6712
Georg Brandl3ee81df2008-05-17 18:14:43 +00006713- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

Georg Brandl3ee81df2008-05-17 18:14:43 +00006729- Patch #1473257: generator objects gain a gi_code attribute. This is
6730 the same object as the func_code attribute of the function that
6731 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006732
Georg Brandl3ee81df2008-05-17 18:14:43 +00006733- Issue #1920: "while 0" statements were completely removed by the
6734 compiler, even in the presence of an "else" clause, which is
6735 supposed to be run when the condition is false. Now the compiler
6736 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006737

Georg Brandl3ee81df2008-05-17 18:14:43 +00006761- Patch #1816: Added sys.flags structseq. It exposes the status of
6762 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006763
Georg Brandl3ee81df2008-05-17 18:14:43 +00006764- Objects/structseq.c: Implemented new structseq representation. The
6765 patch makes structseqs (e.g. the return value of os.stat) more
6766 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006767
Georg Brandl3ee81df2008-05-17 18:14:43 +00006768- Patch #1700288: added a type attribute cache that caches method
6769 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006770
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006771- Bug #1776: __import__() no longer accepts filenames on any platform.
6772 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006773
Georg Brandlaed6c662008-01-07 17:25:53 +00006774- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6775
Georg Brandl3ee81df2008-05-17 18:14:43 +00006776- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6777 envvar and sys.dont_write_bytecode attribute. All these can be set
6778 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006779
Georg Brandl3ee81df2008-05-17 18:14:43 +00006780- Improve some exception messages when Windows fails to load an
6781 extension module. Now we get for example '%1 is not a valid Win32
6782 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006783
Georg Brandl3ee81df2008-05-17 18:14:43 +00006784- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006786- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6787 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006788
Christian Heimes0a8143f2007-12-18 23:22:54 +00006789- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006790 and INF. float("nan"), float("inf") and float("-inf") now work on
6791 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006792
Georg Brandl3ee81df2008-05-17 18:14:43 +00006793- Compiler now generates simpler and faster code for dictionary
6794 literals. The oparg for BUILD_MAP now indicates an estimated
6795 dictionary size. There is a new opcode, STORE_MAP, for adding
6796 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006797
Georg Brandl3ee81df2008-05-17 18:14:43 +00006798- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006800- Issue #1620: New property decorator syntax was modifying the
6801 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006802
Georg Brandl3ee81df2008-05-17 18:14:43 +00006803- Issue #1538: Avoid copying string in split/rsplit if the split char
6804 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006805
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006806- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006807 SystemError.
6808
Nick Coghlanef01d822007-12-03 12:55:17 +00006809- PEP 366: Allow explicit relative imports when executing modules
6810 inside packages with the -m switch via a new module level
6811 __package__ attribute.

6814 running, and if the deallocation of its frames somehow calls the
6815 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006816

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006820 attribute of an empty cell object.
6821
Georg Brandl3ee81df2008-05-17 18:14:43 +00006822- Issue #1460: The utf-7 incremental decoder did not accept truncated
6823 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006824
Georg Brandl3ee81df2008-05-17 18:14:43 +00006825- Patch #1739468: Directories and zipfiles containing a __main__.py
6826 file can now be directly executed by passing their name to the
6827 interpreter. The directory/zipfile is automatically inserted as the
6828 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006829
Georg Brandl3ee81df2008-05-17 18:14:43 +00006830- Issue #1265: Fix a problem with sys.settrace, if the tracing
6831 function uses a generator expression when at the same time the
6832 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006833
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006834- sets and frozensets now have an isdisjoint() method.
6835
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006836- optimize the performance of builtin.sum().
6837
Neal Norwitz44f326e2007-10-05 05:29:17 +00006838- Fix warnings found by the new version of the Coverity checker.
6839
Georg Brandl21e99f42010-03-07 15:23:59 +00006840- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006841 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6842 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006843
Georg Brandl3ee81df2008-05-17 18:14:43 +00006844- Issue #1686386: Tuple's tp_repr did not take into account the
6845 possibility of having a self-referential tuple, which is possible
6846 from C code. Nor did object's tp_str consider that a type's tp_str
6847 could do something that could lead to an inifinite recursion.
6848 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6849 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006850
Georg Brandl3ee81df2008-05-17 18:14:43 +00006851- Issue #1164: It was possible to trigger deadlock when using the
6852 'print' statement to write to a file since the GIL was not released
6853 as needed. Now PyObject_Print() does the right thing along with
6854 various tp_print implementations of the built-in types and those in
6855 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006856
Georg Brandl3ee81df2008-05-17 18:14:43 +00006857- Issue #1147: Exceptions were directly allowing string exceptions in
6858 their throw() method even though string exceptions no longer
6859 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006860
Georg Brandl3ee81df2008-05-17 18:14:43 +00006861- Issue #1096: Prevent a segfault from getting the repr of a very
6862 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006863
Brett Cannon1e534b52007-09-07 04:18:30 +00006864- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006865 PyObject_Call() never calling back out to Python code to trigger
6866 recursion depth updates/checks. Required the creation of a static
6867 RuntimeError instance in case normalizing an exception put the
6868 recursion check value past its limit. Fixes crashers
6869 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006870
Georg Brandl3ee81df2008-05-17 18:14:43 +00006871- Patch #1031213: Decode source line in SyntaxErrors back to its

6875 with %G.
6876
Georg Brandl3ee81df2008-05-17 18:14:43 +00006877- Prevent expandtabs() on string and unicode objects from causing a
6878 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006884- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006885 __*__ attributes. (Some already existed, e.g., __doc__ and
6886 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006887
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006888- Add -3 option to the interpreter to warn about features that are
6889 deprecated and will be changed/removed in Python 3.0.
6890
Georg Brandl2134e752007-05-21 20:34:16 +00006891- Patch #1686487: you can now pass any mapping after '**' in function
6892 calls.
6893
Collin Winter62903052007-05-18 23:11:24 +00006894- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006895 "except E as target:". This is to provide forwards compatibility
6896 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006897
Brett Cannon229cee22007-05-05 01:34:02 +00006898- Deprecate BaseException.message as per PEP 352.
6899
Georg Brandl3ee81df2008-05-17 18:14:43 +00006900- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006901 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006902
Vinay Sajip8549ce32007-05-06 17:53:37 +00006903- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006904 setting a plain string, ie don't expand to single letter identifiers.
6905
Raymond Hettinger13936692007-04-11 18:40:58 +00006906- Request #1191699: Slices can now be pickled.
6907
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006908- Request #1193128: str.translate() now allows a None argument for
6909 translations that only remove characters without re-mapping the
6910 remaining characters.
6911
Georg Brandl5cb76c12007-03-21 09:00:39 +00006912- Patch #1682205: a TypeError while unpacking an iterable is no longer
6913 masked by a generic one with the message "unpack non-sequence".
6914
Neal Norwitzaa754b72007-03-21 06:39:48 +00006915- Remove unused file Python/fmod.c.
6916
Guido van Rossum143b5642007-03-23 04:58:42 +00006917- Bug #1683368: The object.__init__() and object.__new__() methods are
6918 now stricter in rejecting excess arguments. The only time when
6919 either allows excess arguments is when it is not overridden and the
6920 other one is. For backwards compatibility, when both are
6921 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006922 warning later). Also, type.__init__() insists on the same signature
6923 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006924
Georg Brandl3ee81df2008-05-17 18:14:43 +00006925- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6926 object to complex using its __complex__() method before falling back
6927 to the __float__() method. Therefore, the functions in the cmath
6928 module now can operate on objects that define a __complex__()
6929 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006930
Georg Brandl3ee81df2008-05-17 18:14:43 +00006931- Patch #1623563: allow __class__ assignment for classes with
6932 __slots__. The old and the new class are still required to have the
6933 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006934
Georg Brandl3ee81df2008-05-17 18:14:43 +00006935- Patch #1642547: Fix an error/crash when encountering syntax errors
6936 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006938- Patch #1462488: Python no longer segfaults when
6939 ``object.__reduce_ex__()`` is called with an object that is faking
6940 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006941
Georg Brandl3ee81df2008-05-17 18:14:43 +00006942- Patch #1680015: Don't modify __slots__ tuple if it contains an

6946
Georg Brandl7b9c5552007-03-12 14:30:05 +00006947- Bug #1678647: write a newline after printing an exception in any
6948 case, even when converting the value to a string failed.
6949
Georg Brandl871f1bc2007-03-12 13:17:36 +00006950- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006951 its argument, if it exists. If not, it will work like before. This
6952 allows customizing the output of dir() in the presence of a
6953 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006954
Collin Winter276887b2007-03-12 16:11:39 +00006955- Patch #922167: Python no longer segfaults when faced with infinitely
6956 self-recursive reload() calls (as reported by bug #742342).
6957
Georg Brandl3ee81df2008-05-17 18:14:43 +00006958- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00006961- Patch #1491866: change the complex() constructor to allow
6962 parthensized forms. This means complex(repr(x)) now works instead of
6963 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006964
Georg Brandlaa2321b2007-03-07 00:40:28 +00006965- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006966 makes the filenames the warning module prints much more sensible
6967 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006968
Georg Brandl49aafc92007-03-07 00:34:46 +00006969- Variant of patch #697613: don't exit the interpreter on a SystemExit
6970 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006971 variable is given, but break into the interactive interpreter just
6972 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006977- Bug #1674503: close the file opened by execfile() in an error
6978 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00006979
Georg Brandl0fca97a2007-03-05 22:28:08 +00006980- Patch #1674228: when assigning a slice (old-style), check for the
6981 sq_ass_slice instead of the sq_slice slot.
6982
Georg Brandl3ee81df2008-05-17 18:14:43 +00006983- When printing an unraisable error, don't print exceptions. before
6984 the name. This duplicates the behavior whening normally printing
6985 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00006986
Georg Brandl3ee81df2008-05-17 18:14:43 +00006987- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007487- Added a timeout parameter to the constructor of other protocols
7488 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7489 work started with create_connection() and timeout in httplib, and
7490 closes patch #723312.
7491
Vinay Sajip8549ce32007-05-06 17:53:37 +00007492- Patch #1676823: Added create_connection() to socket.py, which may be
7493 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007494 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007495

7516
Georg Brandlf66b6032007-03-14 08:27:52 +00007517- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007518 AttributeError instead of an IOError when the server's response
7519 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007520

Georg Brandl3ee81df2008-05-17 18:14:43 +00007525- Patch #1429539: pdb now correctly initializes the __main__ module
7526 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007527 correctly now.
7528

7535
Georg Brandl3ee81df2008-05-17 18:14:43 +00007536- Patch #1530482: add pydoc.render_doc() which returns the

7546 parameter which can be set to False to prevent the default
7547 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007548
Georg Brandl9e6b4702007-03-13 18:15:41 +00007549- Patch #1581073: add a flag to textwrap that prevents the dropping of
7550 whitespace while wrapping.
7551
Georg Brandl92a6bae2007-03-13 17:43:32 +00007552- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007553 are set for invalid interpolation sequences that would lead to
7554 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007555

Georg Brandl3ee81df2008-05-17 18:14:43 +00007570 field names in its exception message if you try to write a record
7571 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00007589

7597 returned string up to the first NUL character.
7598

7608
Georg Brandl3ee81df2008-05-17 18:14:43 +00007609- unittest now verifies more of its assumptions. In particular,
7610 TestCase and TestSuite subclasses (not instances) are no longer
7611 accepted in TestSuite.addTest(). This should cause no
7612 incompatibility since it never made sense with ordinary subclasses
7613 -- the failure just occurred later, with a more cumbersome
7614 exception.

7624
Georg Brandl3ee81df2008-05-17 18:14:43 +00007625- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00008003 time so that opening a database previously created with the DB_DUP
8004 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8005 opens. Specifically: dictionary assignment to a DB object will
8006 replace all values for a given key when the database allows
8007 duplicate values. DB users should use DB.put(k, v) when they want
8008 to store duplicates; not DB[k] = v.

8015 characters with ASCII value less than 32. Also, it correctly quotes
8016 dots only if they occur on a single line, as opposed to the previous
8017 behavior of quoting dots if they are the second character of any
8018 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008396- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8397 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
