39 longer include a "manifest" to prevent them failing at import time in some
40 embedded situations.

Mark Dickinsondbbed042011-09-19 16:38:08 +010051- Issue #12973: Fix overflow checks that invoked undefined behaviour in
52 int.__pow__. These overflow checks were causing int.__pow__ to produce
53 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010054 compiler optimizing the check away. Also fix similar overflow checks
55 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
56 bugs caused test failures with recent versions of Clang.

68 cleared by the garbage collector. This fixes a segfault when an instance
69 and its type get caught in a reference cycle, and the instance's
70 deallocator calls one of the methods on the type (e.g. when subclassing
71 IOBase). Diagnosis and patch by Davide Rizzo.

Ned Deily87e82bb2011-06-28 19:52:59 -0700337- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
338 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
339 interpreter process. This could cause failures in non-Distutils subprocesses
340 and was unreliable since tests or user programs could modify the interpreter
341 environment after Distutils set it. Instead, have Distutils set the the
342 deployment target only in the environment of each build subprocess. It is
343 still possible to globally override the default by setting
344 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
345 greater or equal to the default value, the value with which the interpreter
346 was built.

376 the ticker doesn't have to wind down to zero from the old starting point
377 before the new interval takes effect. And if the user increases the
378 interval, it makes sure the new limit takes effect right away rather have an
379 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00001302- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1303 This prevents user-created self-referencing ordered dictionaries from
1304 becoming permanently uncollectable GC garbage. The downside is that
1305 removing __del__ means that the internal doubly-linked list has to wait for
1306 GC collection rather than freeing memory immediately when the refcnt drops
1307 to zero.
1308

1314 would swallow the exception and raise a new one, making it impossible
1315 to fetch the original errno, or to filter timeout errors. Now the
1316 original error is re-raised.
1317
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001318- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

1337
R. David Murray7c4bf552010-08-25 01:45:57 +00001338- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1339 character years even if the message contains RFC822 two character years.
1340
Daniel Stutzbach91287322010-08-24 21:09:30 +00001341- Issue #8750: Fixed MutableSet's methods to correctly handle

1354
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001355- Issue #9617: Signals received during a low-level write operation aren't

1357
Benjamin Peterson52c36052010-08-21 03:03:22 +00001358- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1360
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001361- Issue #9626: the view methods for collections.OrderedDict() were returning

1370 and a BadZipfile error is raised if it doesn't match (as used to be the
1371 case in Python 2.5 and earlier).
1372
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001373- Issue #9550: a BufferedReader could issue an additional read when the
1374 original read request had been satisfied, which could block indefinitely
1375 when the underlying raw IO channel was e.g. a socket. Report and original
1376 patch by Jason V. Miller.
1377
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001378- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00001396- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
1397 This is how it is supposed to work, wget and curl do the same. Previous

1781 objects. (1) The comparison could incorrectly return True in some cases
1782 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1783 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00002026- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
2027 the method could block indefinitely if called just before the event loop

2032 indefinitely if the other end didn't respond.
2033
Georg Brandlfee0f442010-05-22 21:26:21 +00002034- The do_handshake() method of SSL objects now adjusts the blocking mode of the

2155 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00002167- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2168 with a non-empty format string. This is an effort to future-proof user
2169 code. If a derived class does not currently implement __format__ but later
2170 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002171 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002172 Python 3.3 and it will be an error in Python 3.4.

2223 InvalidOperation instead of returning False. (Comparisons involving a quiet
2224 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2225 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00002227- Issue #2531: Comparison operations between floats and Decimal instances now
2228 return a result based on the numeric values of the operands; previously they
2229 returned an arbitrary result based on the relative ordering of id(float) and
2230 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00002244- Comparisons using one of <, <=, >, >= between a complex instance and a
2245 Fractions instance now raise TypeError instead of returning True/False. This
2246 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2247 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002609- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2610 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2611 returning NULL. The macro now returns a statically allocated empty string
2612 instead.

2622 strings,
2623 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2624 numeric strings corresponding to subnormal values,
2625 (3) a memory leak for some values large enough to cause overflow, and
2626 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002657- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002658 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002664- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002665 file position when calling `truncate()`. It would previously change the file
2666 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002667 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2668
Georg Brandlba83f822010-03-14 09:50:54 +00002669- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2670 class used to represent files stored inside an archive. The new
2671 implementation is significantly faster and can be wrapped in a
2672 ``io.BufferedReader`` object for more speedups. It also solves an issue
2673 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002684- Issue #7748: Since unicode values are supported for some metadata options in
2685 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2686 encoded string for them. This ensures that the upload and register commands
2687 send the correct values to PyPI without any error.

2763
Georg Brandlba83f822010-03-14 09:50:54 +00002764- The ``__complex__()`` method is now looked up on the class of instances to
2765 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002767- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2768 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2769
Mark Dickinson1b34d252010-01-01 17:27:30 +00002770- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002771 DeprecationWarning when passed a float argument where an integer was expected.
2772 These functions and methods now raise TypeError instead. The majority of the
2773 effects of this change are in the extension modules, but some core functions
2774 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2775 and many unicode/str methods.

2787
Georg Brandlba83f822010-03-14 09:50:54 +00002788- Issue #1811: Improve accuracy and cross-platform consistency for true division
2789 of integers: the result of a/b is now correctly rounded for ints a and b (at
2790 least on IEEE 754 platforms), and in particular does not depend on the
2791 internal representation of a long.

2799
Georg Brandlba83f822010-03-14 09:50:54 +00002800 These executables now work properly with the arch(1) command: ``arch -ppc
2801 python`` will start a universal binary version of python in PPC mode (unlike
2802 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00002825 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00002973 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2974 providing correctly-rounded strtod and dtoa C functions. This code is
2975 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2976 the C compiler. There may be a small number of platforms on which correct
2977 operation of this code cannot be guaranteed, so the code is not used: notably,
2978 this applies to platforms where the C double format is not IEEE 754 binary64,
2979 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2980 and Python's configure script is unable to determine how to change the FPU
2981 precision. On these platforms conversions use the platform strtod and dtoa,
2982 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002984- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2985 uses the correctly-rounded string <-> float conversions described above (when
2986 available), and so produces correctly rounded results that will display nicely
2987 under the float repr. There are two related small changes: (1) round now
2988 accepts any class with an ``__index__()`` method for its second argument (but
2989 no longer accepts floats for the second argument), and (2) an excessively
2990 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2991 raises an exception.

3341
Georg Brandlba83f822010-03-14 09:50:54 +00003342- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on

3370 this code path is really executed because I cannot move to such directory on

3397 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4561 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
4562 consistently raises struct.error.

Georg Brandlba83f822010-03-14 09:50:54 +00004568 - Packing a float now always gives a Deprecation Warning. Previously it
4569 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00004571 - If x is not an int, long or float, then packing x will always result in
4572 struct.error. Previously an x with an __int__ method could be packed by
4573 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4574 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4575 neither __int__ nor __long__, TypeError used to be raised (with a
4576 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4577 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004578
Georg Brandlba83f822010-03-14 09:50:54 +00004579 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
4580 argument with an __int__ method can be packed, but use of this feature
4581 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004774- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4775 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4776 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4777 ``printf`` function, whereas PyString_FromFormat has an independent
4778 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon672237d2008-09-09 00:49:16 +00004849 return a list or None rather than a custom object.
4850
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004851- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004875 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4876 for catch_warnings() also led to an improvement in the raising of a
4877 DeprecationWarning related to warnings.warn_explicit().
4878
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004879- The deprecation warnings for the old camelCase threading API were removed.

4901
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004902- Issue #2975: When compiling several extension modules with Visual Studio 2008
4903 from the same python interpreter, some environment variables would grow
4904 without limit.
4905
Benjamin Peterson37346b22008-08-23 20:27:43 +00004906- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004943What's New in Python 2.6 beta 3?
4944================================
4945
Barry Warsaw07a4a382008-08-21 01:15:08 +00004946*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004947
4948Core and Builtins
4949-----------------
4950
Guido van Rossumf8402962008-08-20 15:01:50 +00004951- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4952 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4953 extensions do not automatically benefit from the class attribute
4954 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4955 to their tp_flags field if they care. This is a backwards
4956 compatibility feature; in 3.0, all types will use the cache by
4957 default.
4958
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004959- Keyword arguments can now follow starred arguments. (``f(a, *args,
4960 keyword=23)`` is now valid syntax.)
4961
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004962- ctypes function pointers that are COM methods have a boolean True
4963 value again.
4964
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004965- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4966 by denying s# to parse objects that have a releasebuffer procedure,
4967 and introducing s*.
4968
Georg Brandl1e13ea92008-08-11 09:07:59 +00004969- Issue #3537: Fix an assertion failure when an empty but presized dict
4970 object was stored in the freelist.
4971
Mark Dickinsonb6467572008-08-04 21:30:09 +00004972- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4973 ValueError consistently across platforms.
4974
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004975- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4976 (64bit Unix, for example), unichr() would truncate its argument and return
4977 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4978
Neal Norwitze7d8be82008-07-31 17:17:14 +00004979- Apply security patches from Apple.
4980
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004981- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4982 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4983
Antoine Pitrou92f82162008-07-25 22:22:08 +00004984- Issue #1819: function calls with several named parameters are now on
4985 average 35% faster (as measured by pybench).
4986
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004987- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4988 the python debugger steps into a class statement: the free variables (local
4989 variables defined in an outer scope) would be deleted from the outer scope.
4990
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004991- Issue #2620: Overflow checking when allocating or reallocating memory
4992 was not always being done properly in some python types and extension
4993 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4994 all been updated to perform better checks and places in the code that
4995 would previously leak memory on the error path when such an allocation
4996 failed have been fixed.

4999-------
5000
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005001- Issue #3612: Added some missing basic types in ctypes.wintypes.
5002
Benjamin Petersone977ad42008-08-20 01:42:01 +00005003- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5004 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5005
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005006- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5007 version reported by these tools does not necessarily follow the python
5008 version numbering scheme, so the module is less strict when parsing it.
5009
Nick Coghlanf70385a2008-08-18 12:42:46 +00005010- Issue #2235: Added Py3k warnings for types which will become unhashable
5011 under the stricter __hash__ inheritance rules in 3.0. Several types
5012 which did not meet the rules for hash invariants and were already
5013 unhashable in 3.0 have now been explicitly flagged as unhashable in
5014 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5015 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5016
Brett Cannon88f801d2008-08-18 00:46:22 +00005017- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5025
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005026- Issue #3575: Incremental decoder's decode function now takes bytearray
5027 by using 's*' instead of 't#'.
5028
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005029- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005030 fails unicode conversion on 2nd parameter. (windows only)
5031
Georg Brandl222e2082010-08-01 22:27:39 +00005032- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005033 in a redirect.
5034
Brett Cannonabe423e2008-08-16 21:47:07 +00005035- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005036 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005037
Facundo Batistaeb90b782008-08-16 14:44:07 +00005038- Issue #2776: fixed small issue when handling an URL with double slash
5039 after a 302 response in the case of not going through a proxy.
5040
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005041- Issue #2676: in the email package, content-type parsing was hanging on
5042 pathological input because of quadratic or exponential behaviour of a
5043 regular expression.
5044
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005045- Issue #3476: binary buffered reading through the new "io" library is now
5046 thread-safe.
5047
Brett Cannonbf3157b2008-08-14 05:00:03 +00005048- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5049 since mimetools itself is deprecated. Because modules are cached, all
5050 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5051
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005052- Issue #3134: shutil referenced undefined WindowsError symbol.
5053
Robert Schuppenies14646332008-08-10 11:01:53 +00005054- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5055 menu entries were not deleted.
5056
Brett Cannon83e81842008-08-09 23:30:55 +00005057- Copied the implementation of reduce() to _functools.reduce() to have a
5058 version that did not raise a DeprecationWarning under -3.
5059
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005060- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5061 a MemoryError rather than silently stop the iteration.
5062
Guido van Rossum59ce9012008-08-09 14:55:34 +00005063- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5064 to _sre.compile() will now be rejected. This should not affect anybody
5065 since the re.compile() function never generates invalid re-bytecode.
5066
Skip Montanaroa032bf42008-08-08 22:52:51 +00005067- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5068 upon first access it can be automatically initialized from the csv file if
5069 it wasn't initialized during instantiation.
5070
Brett Cannon3aa2a492008-08-06 22:28:09 +00005071- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5072 the reload() built-in has been removed.
5073
Brett Cannon7e30b672008-08-04 21:52:25 +00005074- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005075 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005086 asking for a specific length. This problem only affected files opened
5087 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005088

5113 file name rather than a ZipInfo instance, so files are extracted with
5114 mode 0600 rather than 000 under Unix.

Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005116- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5117 argument in python 2.5, this broke code that subclassed Popen to include its
5118 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5130
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005131- Issue #643841: The language reference now provides more detailed
5132 coverage of the lookup process for special methods. The disclaimers
5133 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005137What's New in Python 2.6 beta 2?
5138================================
5139
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005140*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005142Core and Builtins
5143-----------------
5144
Georg Brandl3e483f62008-07-16 22:57:41 +00005145- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5146 its methods now allow for items objects that can be converted to
5147 an integer using operator.index().
5148
Mark Dickinson64b7e502008-07-16 09:40:03 +00005149- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5150 produced a ValueError instead of giving the correct float.
5151
Eric Smitha5fa5a22008-07-16 00:11:49 +00005152- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5153 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5154
Mark Dickinson7103aa42008-07-15 19:08:33 +00005155- Issue #3008: the float type has a new instance method 'float.hex'
5156 and a new class method 'float.fromhex' to convert floating-point
5157 numbers to and from hexadecimal strings, respectively.
5158
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005159- Issue #2235: __hash__ is once again inherited by default. To allow
5160 collections.Hashable to remain meaningful in the presence of the
5161 default hash implementation (object.__hash__), it is now possible
5162 to explicit block inheritance of hash by setting __hash__=None at
5163 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5164 level.
5165
Nick Coghlanb028f502008-07-13 14:52:36 +00005166- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5167 the parent module cannot be found while performing an absolute import.
5168 This means that an incorrectly defined __package__ attribute will
5169 now only prevent relative imports in that module rather than causing
5170 all imports from that module to fail.
5171
Nick Coghlan14ff9942008-07-08 14:21:42 +00005172- Issue #2517: Allow unicode messages in Exceptions again by correctly
5173 bypassing the instance dictionary when looking up __unicode__ on
5174 new-style classes.

Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005176- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5177 set to a custom object whose write() method happens to install
5178 another file in sys.stdout.
5179
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005180- Issue #3088: Corrected a race condition in classes derived from
5181 threading.local: the first member set by a thread could be saved in
5182 another thread's dictionary.
5183
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005184- Issue #3004: Minor change to slice.indices(): the start and stop
5185 arguments are now treated identically, making the behaviour easier
5186 to describe and understand. For example, slice(None, -10,
5187 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5188 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5189 10, -1).
5190
Georg Brandl278fc502008-07-19 12:46:12 +00005191- Issue #3219: Calling a function with repeated keyword arguments,
5192 f(a=2, a=23), would not cause a syntax error. This was a regression
5193 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005194
Georg Brandl278fc502008-07-19 12:46:12 +00005195- Issue #2862: Make int and float freelist management consistent with
5196 other freelists. Changes their CompactFreeList apis into
5197 ClearFreeList apis and calls them via gc.collect().

5203 api functions without holding the GIL, which could lead to a fatal
5204 error when they failed.
5205
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005206- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5228
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005229- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005230
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005231- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5232 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005233 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005234 content-length. The problem had been corrected in the 2.4 branch, but never
5235 merged into trunk.
5236

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005250- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5251 handling is now the same as that of other special attributes like __name__).
5252
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005253- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5707 using the 'warning's machinery in such places as the parser where
5708 use of pure Python code is not possible. Both the ``showarning()``
5709 and ``formatwarning()`` gain an optional 'line' argument which is
5710 not called by default for backwards-compatibility reasons. Setting
5711 ``warnings.showwarning()`` to an implementation that lacks support
5712 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005775- Issue #2550: The approach used by client/server code for obtaining
5776 ports to listen on in network-oriented tests has been refined in an
5777 effort to facilitate running multiple instances of the entire
5778 regression test suite in parallel without issue.
5779 test_support.bind_port() has been fixed such that it will always
5780 return a unique port -- which wasn't always the case with the
5781 previous implementation, especially if socket options had been set
5782 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5783 new implementation of bind_port() will actually raise an exception
5784 if it is passed an AF_INET/SOCK_STREAM socket with either the
5785 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5786 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5787 the socket it's been passed. This currently only applies to
5788 Windows. This option prevents any other sockets from binding to the
5789 host/port we've bound to, thus removing the possibility of the
5790 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5791 when a second SOCK_STREAM socket binds and accepts to a host/port
5792 that's already been bound by another socket. The optional preferred
5793 port parameter to bind_port() has been removed. Under no
5794 circumstances should tests be hard coding ports!
5795
5796 test_support.find_unused_port() has also been introduced, which will
5797 pass a temporary socket object to bind_port() in order to obtain an
5798 unused port. The temporary socket object is then closed and
5799 deleted, and the port is returned. This method should only be used
5800 for obtaining an unused port in order to pass to an external program
5801 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5802 a parameter to a server-oriented class that doesn't give you direct
5803 access to the underlying socket used.
5804
5805 Finally, test_support.HOST has been introduced, which should be used
5806 for the host argument of any relevant socket calls (i.e. bind and
5807 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005808
5809 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005810 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005811 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5812 test_asynchat and test_socket_ssl.
5813
Georg Brandl3ee81df2008-05-17 18:14:43 +00005814 It is now possible for multiple instances of the regression test
5815 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006094- Added the future_builtins module, which contains hex() and oct().
6095 These are the PEP 3127 version of these functions, designed to be
6096 compatible with the hex() and oct() builtins from Python 3.0. They
6097 differ slightly in their output formats from the existing, unchanged
6098 Python 2.6 builtins. The expected usage of the future_builtins
6099 module is:
6100 from future_builtins import hex, oct
6101
Eric Smith7ef40bf2008-02-20 23:34:22 +00006102- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6103 exponents for exponents with absolute value < 100. Follows C99
6104 standard. This is a change on Windows, which would use 3 digits.
6105 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6106 so that any alterations it does to the resulting string will be
6107 available in stringlib/formatter.h (for float.__format__).
6108
Eric Smith5a3c1352008-02-19 13:21:56 +00006109- Implemented PEP 3101, Advanced String Formatting. This adds a new
6110 builtin format(); a format() method for str and unicode; a
6111 __format__() method to object, str, unicode, int, long, float, and
6112 datetime; the class string.Formatter; and the C API
6113 PyObject_Format().
6114
Georg Brandl3ee81df2008-05-17 18:14:43 +00006115- Fixed several potential crashes, all caused by specially crafted
6116 __del__ methods exploiting objects in temporarily inconsistent
6117 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006118
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006119- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006120 prevent a possible crash: an Abstract Base Class would try to access
6121 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006126- Clear all free lists during a gc.collect() of the highest generation
6127 in order to allow pymalloc to free more arenas. Python may give back
6128 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006129
Georg Brandl3ee81df2008-05-17 18:14:43 +00006130- Issue #2045: Fix an infinite recursion triggered when printing a
6131 subclass of collections.defaultdict, if its default_factory is set
6132 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006133
Christian Heimesf75dbef2008-02-08 00:11:31 +00006134- Fixed a minor memory leak in dictobject.c. The content of the free
6135 list was not freed on interpreter shutdown.
6136
Georg Brandl21e99f42010-03-07 15:23:59 +00006137- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006139
Georg Brandl3ee81df2008-05-17 18:14:43 +00006140- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6141 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006142 to compact the internal free lists of pre-allocted ints and floats.
6143
Georg Brandl3ee81df2008-05-17 18:14:43 +00006144- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6145 calls. Python expected the return type int but the fork familie
6146 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006147

Georg Brandl3ee81df2008-05-17 18:14:43 +00006160- Patch #1473257: generator objects gain a gi_code attribute. This is
6161 the same object as the func_code attribute of the function that
6162 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006163
Georg Brandl3ee81df2008-05-17 18:14:43 +00006164- Issue #1920: "while 0" statements were completely removed by the
6165 compiler, even in the presence of an "else" clause, which is
6166 supposed to be run when the condition is false. Now the compiler
6167 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006168

Georg Brandl3ee81df2008-05-17 18:14:43 +00006195- Objects/structseq.c: Implemented new structseq representation. The
6196 patch makes structseqs (e.g. the return value of os.stat) more
6197 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006198
Georg Brandl3ee81df2008-05-17 18:14:43 +00006199- Patch #1700288: added a type attribute cache that caches method
6200 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006201
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006202- Bug #1776: __import__() no longer accepts filenames on any platform.
6203 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00006205- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6206
Georg Brandl3ee81df2008-05-17 18:14:43 +00006207- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6208 envvar and sys.dont_write_bytecode attribute. All these can be set
6209 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006210
Georg Brandl3ee81df2008-05-17 18:14:43 +00006211- Improve some exception messages when Windows fails to load an
6212 extension module. Now we get for example '%1 is not a valid Win32
6213 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006214

Christian Heimes0a8143f2007-12-18 23:22:54 +00006220- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006221 and INF. float("nan"), float("inf") and float("-inf") now work on
6222 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006224- Compiler now generates simpler and faster code for dictionary
6225 literals. The oparg for BUILD_MAP now indicates an estimated
6226 dictionary size. There is a new opcode, STORE_MAP, for adding
6227 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006256- Patch #1739468: Directories and zipfiles containing a __main__.py
6257 file can now be directly executed by passing their name to the
6258 interpreter. The directory/zipfile is automatically inserted as the
6259 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006261- Issue #1265: Fix a problem with sys.settrace, if the tracing
6262 function uses a generator expression when at the same time the
6263 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006264
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006265- sets and frozensets now have an isdisjoint() method.
6266

6270
Georg Brandl21e99f42010-03-07 15:23:59 +00006271- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006272 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6273 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006274
Georg Brandl3ee81df2008-05-17 18:14:43 +00006275- Issue #1686386: Tuple's tp_repr did not take into account the
6276 possibility of having a self-referential tuple, which is possible
6277 from C code. Nor did object's tp_str consider that a type's tp_str
6278 could do something that could lead to an inifinite recursion.
6279 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6280 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006281
Georg Brandl3ee81df2008-05-17 18:14:43 +00006282- Issue #1164: It was possible to trigger deadlock when using the
6283 'print' statement to write to a file since the GIL was not released
6284 as needed. Now PyObject_Print() does the right thing along with
6285 various tp_print implementations of the built-in types and those in
6286 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006287
Georg Brandl3ee81df2008-05-17 18:14:43 +00006288- Issue #1147: Exceptions were directly allowing string exceptions in
6289 their throw() method even though string exceptions no longer
6290 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00006294
Brett Cannon1e534b52007-09-07 04:18:30 +00006295- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006296 PyObject_Call() never calling back out to Python code to trigger
6297 recursion depth updates/checks. Required the creation of a static
6298 RuntimeError instance in case normalizing an exception put the
6299 recursion check value past its limit. Fixes crashers
6300 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006301

Neal Norwitz0ac60192007-05-27 04:08:54 +00006315- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006316 __*__ attributes. (Some already existed, e.g., __doc__ and
6317 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006318
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006319- Add -3 option to the interpreter to warn about features that are
6320 deprecated and will be changed/removed in Python 3.0.
6321
Georg Brandl2134e752007-05-21 20:34:16 +00006322- Patch #1686487: you can now pass any mapping after '**' in function
6323 calls.
6324
Collin Winter62903052007-05-18 23:11:24 +00006325- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006326 "except E as target:". This is to provide forwards compatibility
6327 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006334- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006335 setting a plain string, ie don't expand to single letter identifiers.
6336
Raymond Hettinger13936692007-04-11 18:40:58 +00006337- Request #1191699: Slices can now be pickled.
6338
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006339- Request #1193128: str.translate() now allows a None argument for
6340 translations that only remove characters without re-mapping the
6341 remaining characters.
6342
Georg Brandl5cb76c12007-03-21 09:00:39 +00006343- Patch #1682205: a TypeError while unpacking an iterable is no longer
6344 masked by a generic one with the message "unpack non-sequence".
6345
Neal Norwitzaa754b72007-03-21 06:39:48 +00006346- Remove unused file Python/fmod.c.
6347
Guido van Rossum143b5642007-03-23 04:58:42 +00006348- Bug #1683368: The object.__init__() and object.__new__() methods are
6349 now stricter in rejecting excess arguments. The only time when
6350 either allows excess arguments is when it is not overridden and the
6351 other one is. For backwards compatibility, when both are
6352 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006353 warning later). Also, type.__init__() insists on the same signature
6354 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006355
Georg Brandl3ee81df2008-05-17 18:14:43 +00006356- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6357 object to complex using its __complex__() method before falling back
6358 to the __float__() method. Therefore, the functions in the cmath
6359 module now can operate on objects that define a __complex__()
6360 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006361
Georg Brandl3ee81df2008-05-17 18:14:43 +00006362- Patch #1623563: allow __class__ assignment for classes with
6363 __slots__. The old and the new class are still required to have the
6364 same slot names.

6377
Georg Brandl7b9c5552007-03-12 14:30:05 +00006378- Bug #1678647: write a newline after printing an exception in any
6379 case, even when converting the value to a string failed.
6380
Georg Brandl871f1bc2007-03-12 13:17:36 +00006381- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006382 its argument, if it exists. If not, it will work like before. This
6383 allows customizing the output of dir() in the presence of a
6384 __getattr__().

6393 parthensized forms. This means complex(repr(x)) now works instead of
6394 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006395
Georg Brandlaa2321b2007-03-07 00:40:28 +00006396- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006397 makes the filenames the warning module prints much more sensible
6398 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006399

Georg Brandl0fca97a2007-03-05 22:28:08 +00006411- Patch #1674228: when assigning a slice (old-style), check for the
6412 sq_ass_slice instead of the sq_slice slot.
6413
Georg Brandl3ee81df2008-05-17 18:14:43 +00006414- When printing an unraisable error, don't print exceptions. before
6415 the name. This duplicates the behavior whening normally printing
6416 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006918- Added a timeout parameter to the constructor of other protocols
6919 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6920 work started with create_connection() and timeout in httplib, and
6921 closes patch #723312.
6922

6924 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006925 and HTTPSConnection now accept an optional timeout).

6947
Georg Brandlf66b6032007-03-14 08:27:52 +00006948- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006949 AttributeError instead of an IOError when the server's response
6950 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006951

Georg Brandl3ee81df2008-05-17 18:14:43 +00006956- Patch #1429539: pdb now correctly initializes the __main__ module
6957 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006958 correctly now.
6959

6966
Georg Brandl3ee81df2008-05-17 18:14:43 +00006967- Patch #1530482: add pydoc.render_doc() which returns the

6977 parameter which can be set to False to prevent the default
6978 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00006979
Georg Brandl9e6b4702007-03-13 18:15:41 +00006980- Patch #1581073: add a flag to textwrap that prevents the dropping of
6981 whitespace while wrapping.
6982
Georg Brandl92a6bae2007-03-13 17:43:32 +00006983- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006984 are set for invalid interpolation sequences that would lead to
6985 errors on reading back those values.

7028 returned string up to the first NUL character.
7029

7039
Georg Brandl3ee81df2008-05-17 18:14:43 +00007040- unittest now verifies more of its assumptions. In particular,
7041 TestCase and TestSuite subclasses (not instances) are no longer
7042 accepted in TestSuite.addTest(). This should cause no
7043 incompatibility since it never made sense with ordinary subclasses
7044 -- the failure just occurred later, with a more cumbersome
7045 exception.

7055
Georg Brandl3ee81df2008-05-17 18:14:43 +00007056- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00007434 time so that opening a database previously created with the DB_DUP
7435 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7436 opens. Specifically: dictionary assignment to a DB object will
7437 replace all values for a given key when the database allows
7438 duplicate values. DB users should use DB.put(k, v) when they want
7439 to store duplicates; not DB[k] = v.

7446 characters with ASCII value less than 32. Also, it correctly quotes
7447 dots only if they occur on a single line, as opposed to the previous
7448 behavior of quoting dots if they are the second character of any
7449 line.
