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

Mark Dickinsondbbed042011-09-19 16:38:08 +010052- Issue #12973: Fix overflow checks that invoked undefined behaviour in
53 int.__pow__. These overflow checks were causing int.__pow__ to produce
54 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010055 compiler optimizing the check away. Also fix similar overflow checks
56 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
57 bugs caused test failures with recent versions of Clang.

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

82 raw_input() interrupted by CTRL+c.

88 name.

Ned Deily87e82bb2011-06-28 19:52:59 -0700338- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
339 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
340 interpreter process. This could cause failures in non-Distutils subprocesses
341 and was unreliable since tests or user programs could modify the interpreter
342 environment after Distutils set it. Instead, have Distutils set the the
343 deployment target only in the environment of each build subprocess. It is
344 still possible to globally override the default by setting
345 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
346 greater or equal to the default value, the value with which the interpreter
347 was built.

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

1293 by Andrew Bennetts.

1302
Raymond Hettinger20397532010-09-12 02:11:45 +00001303- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1304 This prevents user-created self-referencing ordered dictionaries from
1305 becoming permanently uncollectable GC garbage. The downside is that
1306 removing __del__ means that the internal doubly-linked list has to wait for
1307 GC collection rather than freeing memory immediately when the refcnt drops
1308 to zero.
1309
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001310- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1313
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001314- Issue #9792: In case of connection failure, socket.create_connection()
1315 would swallow the exception and raise a new one, making it impossible
1316 to fetch the original errno, or to filter timeout errors. Now the
1317 original error is re-raised.
1318
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001319- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
1320 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
1321 be updated back after the system call. Original patch by Brian Brazil.

1328
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00001329- Issue #808164: Fixed socket.close to avoid references to globals, to
1330 avoid issues when socket.close is called from a __del__ method.
1331
Terry Reedyd2d2ae92010-11-11 23:22:19 +00001332- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
1333 can be set to False to turn off the previously undocumented 'popularity'
1334 heuristic. Patch by Terry Reedy and Eli Bendersky
1335
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00001336- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
1337 falling into recursion.
1338
R. David Murray7c4bf552010-08-25 01:45:57 +00001339- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1340 character years even if the message contains RFC822 two character years.
1341
Daniel Stutzbach91287322010-08-24 21:09:30 +00001342- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00001353- Issue #9214: Set operations on KeysView or ItemsView in the collections
1354 module now correctly return a set. (Patch by Eli Bendersky.)
1355
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001356- Issue #9617: Signals received during a low-level write operation aren't
1357 ignored by the buffered IO layer anymore.
1358
Benjamin Peterson52c36052010-08-21 03:03:22 +00001359- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
1360 are not held onto after they are deleted elsewhere.
1361
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001362- Issue #9626: the view methods for collections.OrderedDict() were returning
1363 the unordered versions inherited from dict. Those methods are now
1364 overridden to provide ordered views.
1365
Éric Araujo0389ae62010-08-14 03:07:46 +00001366- Issue #8688: MANIFEST files created by distutils now include a magic
1367 comment indicating they are generated. Manually maintained MANIFESTs
1368 without this marker will not be overwritten or removed.
1369
Antoine Pitroue1436d12010-08-12 15:25:51 +00001370- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
1371 and a BadZipfile error is raised if it doesn't match (as used to be the
1372 case in Python 2.5 and earlier).
1373
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001374- Issue #9550: a BufferedReader could issue an additional read when the
1375 original read request had been satisfied, which could block indefinitely
1376 when the underlying raw IO channel was e.g. a socket. Report and original
1377 patch by Jason V. Miller.
1378
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001379- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00001397- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
1398 This is how it is supposed to work, wget and curl do the same. Previous
1399 behavior was wrong.

1407 the option character for the added 'h/help' option if prefix_chars
1408 does not contain a '-', instead of raising an error.
1409

Georg Brandlfee0f442010-05-22 21:26:21 +00002027- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
2028 the method could block indefinitely if called just before the event loop
2029 started running. This also fixes the occasional freezes witnessed in
2030 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +00002032- Issue #5103: SSL handshake would ignore the socket timeout and block
2033 indefinitely if the other end didn't respond.
2034
Georg Brandlfee0f442010-05-22 21:26:21 +00002035- The do_handshake() method of SSL objects now adjusts the blocking mode of the
2036 SSL structure if necessary (as other methods already do).

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002128 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002153- Issue #7301: Add environment variable $PYTHONWARNINGS.
2154
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002155- Issue #8329: Don't return the same lists from select.select when no fds are
2156 changed.
2157
Georg Brandlfee0f442010-05-22 21:26:21 +00002158- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002159 on 64-bit machines. The shift count for either left or right shift is
2160 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00002168- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2169 with a non-empty format string. This is an effort to future-proof user
2170 code. If a derived class does not currently implement __format__ but later
2171 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002172 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002173 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002206- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00002223- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2224 InvalidOperation instead of returning False. (Comparisons involving a quiet
2225 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2226 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002227
Georg Brandlfee0f442010-05-22 21:26:21 +00002228- Issue #2531: Comparison operations between floats and Decimal instances now
2229 return a result based on the numeric values of the operands; previously they
2230 returned an arbitrary result based on the relative ordering of id(float) and
2231 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00002234 argument `-` which tells it to read files to compile from stdin. Each line is

Georg Brandlfee0f442010-05-22 21:26:21 +00002245- Comparisons using one of <, <=, >, >= between a complex instance and a
2246 Fractions instance now raise TypeError instead of returning True/False. This
2247 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2248 <=> complex, and complex <=> complex comparisons.

2611 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2612 returning NULL. The macro now returns a statically allocated empty string

2623 strings,
2624 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2625 numeric strings corresponding to subnormal values,

Georg Brandlba83f822010-03-14 09:50:54 +00002659 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002665- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002666 file position when calling `truncate()`. It would previously change the file
2667 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002668 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2669

2671 class used to represent files stored inside an archive. The new
2672 implementation is significantly faster and can be wrapped in a
2673 ``io.BufferedReader`` object for more speedups. It also solves an issue
2674 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002685- Issue #7748: Since unicode values are supported for some metadata options in
2686 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2687 encoded string for them. This ensures that the upload and register commands
2688 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002765- The ``__complex__()`` method is now looked up on the class of instances to
2766 make it consistent with other special methods.

2770
Mark Dickinson1b34d252010-01-01 17:27:30 +00002771- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002772 DeprecationWarning when passed a float argument where an integer was expected.
2773 These functions and methods now raise TypeError instead. The majority of the
2774 effects of this change are in the extension modules, but some core functions
2775 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2776 and many unicode/str methods.

2788
Georg Brandlba83f822010-03-14 09:50:54 +00002789- Issue #1811: Improve accuracy and cross-platform consistency for true division
2790 of integers: the result of a/b is now correctly rounded for ints a and b (at
2791 least on IEEE 754 platforms), and in particular does not depend on the
2792 internal representation of a long.

2800
Georg Brandlba83f822010-03-14 09:50:54 +00002801 These executables now work properly with the arch(1) command: ``arch -ppc
2802 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00002826 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00002974 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2975 providing correctly-rounded strtod and dtoa C functions. This code is
2976 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2977 the C compiler. There may be a small number of platforms on which correct
2978 operation of this code cannot be guaranteed, so the code is not used: notably,
2979 this applies to platforms where the C double format is not IEEE 754 binary64,
2980 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2981 and Python's configure script is unable to determine how to change the FPU
2982 precision. On these platforms conversions use the platform strtod and dtoa,
2983 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002985- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2986 uses the correctly-rounded string <-> float conversions described above (when
2987 available), and so produces correctly rounded results that will display nicely
2988 under the float repr. There are two related small changes: (1) round now
2989 accepts any class with an ``__index__()`` method for its second argument (but
2990 no longer accepts floats for the second argument), and (2) an excessively
2991 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2992 raises an exception.

3371 this code path is really executed because I cannot move to such directory on

3398 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

4562 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
4563 consistently raises struct.error.

Georg Brandlba83f822010-03-14 09:50:54 +00004569 - Packing a float now always gives a Deprecation Warning. Previously it
4570 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00004572 - If x is not an int, long or float, then packing x will always result in
4573 struct.error. Previously an x with an __int__ method could be packed by
4574 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4575 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4576 neither __int__ nor __long__, TypeError used to be raised (with a
4577 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4578 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004579
Georg Brandlba83f822010-03-14 09:50:54 +00004580 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
4581 argument with an __int__ method can be packed, but use of this feature
4582 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004775- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4776 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4777 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4778 ``printf`` function, whereas PyString_FromFormat has an independent
4779 implementation and uses "%zd" on all platforms for size_t values.

Nick Coghland2e09382008-09-11 12:11:06 +00004849- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004850 return a list or None rather than a custom object.
4851
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004852- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004876 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4877 for catch_warnings() also led to an improvement in the raising of a
4878 DeprecationWarning related to warnings.warn_explicit().
4879
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004880- The deprecation warnings for the old camelCase threading API were removed.

4902
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004903- Issue #2975: When compiling several extension modules with Visual Studio 2008
4904 from the same python interpreter, some environment variables would grow
4905 without limit.
4906
Benjamin Peterson37346b22008-08-23 20:27:43 +00004907- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4908 exploitation of poor argument checking.
4909
Gerhard Häringef2276b2008-09-12 13:54:06 +00004910- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004944What's New in Python 2.6 beta 3?
4945================================
4946
Barry Warsaw07a4a382008-08-21 01:15:08 +00004947*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004948
4949Core and Builtins
4950-----------------
4951
Guido van Rossumf8402962008-08-20 15:01:50 +00004952- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4953 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4954 extensions do not automatically benefit from the class attribute
4955 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4956 to their tp_flags field if they care. This is a backwards
4957 compatibility feature; in 3.0, all types will use the cache by
4958 default.
4959
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004960- Keyword arguments can now follow starred arguments. (``f(a, *args,
4961 keyword=23)`` is now valid syntax.)
4962
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004963- ctypes function pointers that are COM methods have a boolean True
4964 value again.
4965
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004966- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4967 by denying s# to parse objects that have a releasebuffer procedure,
4968 and introducing s*.
4969
Georg Brandl1e13ea92008-08-11 09:07:59 +00004970- Issue #3537: Fix an assertion failure when an empty but presized dict
4971 object was stored in the freelist.
4972
Mark Dickinsonb6467572008-08-04 21:30:09 +00004973- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4974 ValueError consistently across platforms.
4975
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004976- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4977 (64bit Unix, for example), unichr() would truncate its argument and return
4978 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4979
Neal Norwitze7d8be82008-07-31 17:17:14 +00004980- Apply security patches from Apple.
4981
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004982- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4983 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4984
Antoine Pitrou92f82162008-07-25 22:22:08 +00004985- Issue #1819: function calls with several named parameters are now on
4986 average 35% faster (as measured by pybench).
4987
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004988- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4989 the python debugger steps into a class statement: the free variables (local
4990 variables defined in an outer scope) would be deleted from the outer scope.
4991
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004992- Issue #2620: Overflow checking when allocating or reallocating memory
4993 was not always being done properly in some python types and extension
4994 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4995 all been updated to perform better checks and places in the code that
4996 would previously leak memory on the error path when such an allocation
4997 failed have been fixed.

5000-------
5001
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005002- Issue #3612: Added some missing basic types in ctypes.wintypes.
5003
Benjamin Petersone977ad42008-08-20 01:42:01 +00005004- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5005 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5006
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005007- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5008 version reported by these tools does not necessarily follow the python
5009 version numbering scheme, so the module is less strict when parsing it.
5010
Nick Coghlanf70385a2008-08-18 12:42:46 +00005011- Issue #2235: Added Py3k warnings for types which will become unhashable
5012 under the stricter __hash__ inheritance rules in 3.0. Several types
5013 which did not meet the rules for hash invariants and were already
5014 unhashable in 3.0 have now been explicitly flagged as unhashable in
5015 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5016 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5017
Brett Cannon88f801d2008-08-18 00:46:22 +00005018- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005025- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5026
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005027- Issue #3575: Incremental decoder's decode function now takes bytearray
5028 by using 's*' instead of 't#'.
5029
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005030- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005031 fails unicode conversion on 2nd parameter. (windows only)
5032
Georg Brandl222e2082010-08-01 22:27:39 +00005033- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005034 in a redirect.
5035
Brett Cannonabe423e2008-08-16 21:47:07 +00005036- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005037 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005038
Facundo Batistaeb90b782008-08-16 14:44:07 +00005039- Issue #2776: fixed small issue when handling an URL with double slash
5040 after a 302 response in the case of not going through a proxy.
5041
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005042- Issue #2676: in the email package, content-type parsing was hanging on
5043 pathological input because of quadratic or exponential behaviour of a
5044 regular expression.
5045
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005046- Issue #3476: binary buffered reading through the new "io" library is now
5047 thread-safe.
5048
Brett Cannonbf3157b2008-08-14 05:00:03 +00005049- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5050 since mimetools itself is deprecated. Because modules are cached, all
5051 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5052
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005053- Issue #3134: shutil referenced undefined WindowsError symbol.
5054
Robert Schuppenies14646332008-08-10 11:01:53 +00005055- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5056 menu entries were not deleted.
5057
Brett Cannon83e81842008-08-09 23:30:55 +00005058- Copied the implementation of reduce() to _functools.reduce() to have a
5059 version that did not raise a DeprecationWarning under -3.
5060
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005061- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5062 a MemoryError rather than silently stop the iteration.
5063
Guido van Rossum59ce9012008-08-09 14:55:34 +00005064- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5065 to _sre.compile() will now be rejected. This should not affect anybody
5066 since the re.compile() function never generates invalid re-bytecode.
5067
Skip Montanaroa032bf42008-08-08 22:52:51 +00005068- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5069 upon first access it can be automatically initialized from the csv file if
5070 it wasn't initialized during instantiation.
5071
Brett Cannon3aa2a492008-08-06 22:28:09 +00005072- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5073 the reload() built-in has been removed.
5074
Brett Cannon7e30b672008-08-04 21:52:25 +00005075- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005076 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005087 asking for a specific length. This problem only affected files opened
5088 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005089

5114 file name rather than a ZipInfo instance, so files are extracted with
5115 mode 0600 rather than 000 under Unix.

Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005117- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5118 argument in python 2.5, this broke code that subclassed Popen to include its
5119 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5131
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005132- Issue #643841: The language reference now provides more detailed
5133 coverage of the lookup process for special methods. The disclaimers
5134 regarding lack of coverage of new-style classes have also been
5135 removed, since the coverage is now fairly reasonable.

5139================================
5140
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005141*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005143Core and Builtins
5144-----------------
5145
Georg Brandl3e483f62008-07-16 22:57:41 +00005146- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5147 its methods now allow for items objects that can be converted to
5148 an integer using operator.index().
5149
Mark Dickinson64b7e502008-07-16 09:40:03 +00005150- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5151 produced a ValueError instead of giving the correct float.
5152
Eric Smitha5fa5a22008-07-16 00:11:49 +00005153- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5154 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5155
Mark Dickinson7103aa42008-07-15 19:08:33 +00005156- Issue #3008: the float type has a new instance method 'float.hex'
5157 and a new class method 'float.fromhex' to convert floating-point
5158 numbers to and from hexadecimal strings, respectively.
5159
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005160- Issue #2235: __hash__ is once again inherited by default. To allow
5161 collections.Hashable to remain meaningful in the presence of the
5162 default hash implementation (object.__hash__), it is now possible
5163 to explicit block inheritance of hash by setting __hash__=None at
5164 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5165 level.
5166
Nick Coghlanb028f502008-07-13 14:52:36 +00005167- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5168 the parent module cannot be found while performing an absolute import.
5169 This means that an incorrectly defined __package__ attribute will
5170 now only prevent relative imports in that module rather than causing
5171 all imports from that module to fail.
5172
Nick Coghlan14ff9942008-07-08 14:21:42 +00005173- Issue #2517: Allow unicode messages in Exceptions again by correctly
5174 bypassing the instance dictionary when looking up __unicode__ on
5175 new-style classes.

5178 set to a custom object whose write() method happens to install
5179 another file in sys.stdout.
5180
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005181- Issue #3088: Corrected a race condition in classes derived from
5182 threading.local: the first member set by a thread could be saved in
5183 another thread's dictionary.
5184
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005185- Issue #3004: Minor change to slice.indices(): the start and stop
5186 arguments are now treated identically, making the behaviour easier
5187 to describe and understand. For example, slice(None, -10,
5188 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5189 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5190 10, -1).
5191
Georg Brandl278fc502008-07-19 12:46:12 +00005192- Issue #3219: Calling a function with repeated keyword arguments,
5193 f(a=2, a=23), would not cause a syntax error. This was a regression
5194 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005195
Georg Brandl278fc502008-07-19 12:46:12 +00005196- Issue #2862: Make int and float freelist management consistent with
5197 other freelists. Changes their CompactFreeList apis into
5198 ClearFreeList apis and calls them via gc.collect().

5204 api functions without holding the GIL, which could lead to a fatal
5205 error when they failed.
5206
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005207- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005230- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005231
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005232- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5233 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005234 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005235 content-length. The problem had been corrected in the 2.4 branch, but never
5236 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005251- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5252 handling is now the same as that of other special attributes like __name__).
5253
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005254- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

5708 using the 'warning's machinery in such places as the parser where
5709 use of pure Python code is not possible. Both the ``showarning()``
5710 and ``formatwarning()`` gain an optional 'line' argument which is
5711 not called by default for backwards-compatibility reasons. Setting
5712 ``warnings.showwarning()`` to an implementation that lacks support
5713 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005776- Issue #2550: The approach used by client/server code for obtaining
5777 ports to listen on in network-oriented tests has been refined in an
5778 effort to facilitate running multiple instances of the entire
5779 regression test suite in parallel without issue.
5780 test_support.bind_port() has been fixed such that it will always
5781 return a unique port -- which wasn't always the case with the
5782 previous implementation, especially if socket options had been set
5783 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5784 new implementation of bind_port() will actually raise an exception
5785 if it is passed an AF_INET/SOCK_STREAM socket with either the
5786 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5787 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5788 the socket it's been passed. This currently only applies to
5789 Windows. This option prevents any other sockets from binding to the
5790 host/port we've bound to, thus removing the possibility of the
5791 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5792 when a second SOCK_STREAM socket binds and accepts to a host/port
5793 that's already been bound by another socket. The optional preferred
5794 port parameter to bind_port() has been removed. Under no
5795 circumstances should tests be hard coding ports!
5796
5797 test_support.find_unused_port() has also been introduced, which will
5798 pass a temporary socket object to bind_port() in order to obtain an
5799 unused port. The temporary socket object is then closed and
5800 deleted, and the port is returned. This method should only be used
5801 for obtaining an unused port in order to pass to an external program
5802 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5803 a parameter to a server-oriented class that doesn't give you direct
5804 access to the underlying socket used.
5805
5806 Finally, test_support.HOST has been introduced, which should be used
5807 for the host argument of any relevant socket calls (i.e. bind and
5808 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005809
5810 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005811 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005812 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5813 test_asynchat and test_socket_ssl.
5814
Georg Brandl3ee81df2008-05-17 18:14:43 +00005815 It is now possible for multiple instances of the regression test
5816 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006095- Added the future_builtins module, which contains hex() and oct().
6096 These are the PEP 3127 version of these functions, designed to be
6097 compatible with the hex() and oct() builtins from Python 3.0. They
6098 differ slightly in their output formats from the existing, unchanged
6099 Python 2.6 builtins. The expected usage of the future_builtins
6100 module is:
6101 from future_builtins import hex, oct
6102
Eric Smith7ef40bf2008-02-20 23:34:22 +00006103- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6104 exponents for exponents with absolute value < 100. Follows C99
6105 standard. This is a change on Windows, which would use 3 digits.
6106 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6107 so that any alterations it does to the resulting string will be
6108 available in stringlib/formatter.h (for float.__format__).
6109
Eric Smith5a3c1352008-02-19 13:21:56 +00006110- Implemented PEP 3101, Advanced String Formatting. This adds a new
6111 builtin format(); a format() method for str and unicode; a
6112 __format__() method to object, str, unicode, int, long, float, and
6113 datetime; the class string.Formatter; and the C API
6114 PyObject_Format().
6115
Georg Brandl3ee81df2008-05-17 18:14:43 +00006116- Fixed several potential crashes, all caused by specially crafted
6117 __del__ methods exploiting objects in temporarily inconsistent
6118 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006119
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006120- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006121 prevent a possible crash: an Abstract Base Class would try to access
6122 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006127- Clear all free lists during a gc.collect() of the highest generation
6128 in order to allow pymalloc to free more arenas. Python may give back
6129 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006130
Georg Brandl3ee81df2008-05-17 18:14:43 +00006131- Issue #2045: Fix an infinite recursion triggered when printing a
6132 subclass of collections.defaultdict, if its default_factory is set
6133 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006134
Christian Heimesf75dbef2008-02-08 00:11:31 +00006135- Fixed a minor memory leak in dictobject.c. The content of the free
6136 list was not freed on interpreter shutdown.
6137
Georg Brandl21e99f42010-03-07 15:23:59 +00006138- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006140
Georg Brandl3ee81df2008-05-17 18:14:43 +00006141- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6142 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006143 to compact the internal free lists of pre-allocted ints and floats.
6144
Georg Brandl3ee81df2008-05-17 18:14:43 +00006145- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6146 calls. Python expected the return type int but the fork familie
6147 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006148

Georg Brandl3ee81df2008-05-17 18:14:43 +00006161- Patch #1473257: generator objects gain a gi_code attribute. This is
6162 the same object as the func_code attribute of the function that
6163 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006164
Georg Brandl3ee81df2008-05-17 18:14:43 +00006165- Issue #1920: "while 0" statements were completely removed by the
6166 compiler, even in the presence of an "else" clause, which is
6167 supposed to be run when the condition is false. Now the compiler
6168 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006169
Guido van Rossumeead05f2008-01-24 18:21:02 +00006170- A few crashers fixed: weakref_in_del.py (issue #1377858);

6177
Georg Brandl3ee81df2008-05-17 18:14:43 +00006178- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006179 several extension methods and modules do not work without unicode
6180 support.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006196- Objects/structseq.c: Implemented new structseq representation. The
6197 patch makes structseqs (e.g. the return value of os.stat) more
6198 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006199
Georg Brandl3ee81df2008-05-17 18:14:43 +00006200- Patch #1700288: added a type attribute cache that caches method
6201 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006202
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006203- Bug #1776: __import__() no longer accepts filenames on any platform.
6204 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00006206- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6207
Georg Brandl3ee81df2008-05-17 18:14:43 +00006208- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6209 envvar and sys.dont_write_bytecode attribute. All these can be set
6210 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006211
Georg Brandl3ee81df2008-05-17 18:14:43 +00006212- Improve some exception messages when Windows fails to load an
6213 extension module. Now we get for example '%1 is not a valid Win32
6214 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006215

Christian Heimes0a8143f2007-12-18 23:22:54 +00006221- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006222 and INF. float("nan"), float("inf") and float("-inf") now work on
6223 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006225- Compiler now generates simpler and faster code for dictionary
6226 literals. The oparg for BUILD_MAP now indicates an estimated
6227 dictionary size. There is a new opcode, STORE_MAP, for adding
6228 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006257- Patch #1739468: Directories and zipfiles containing a __main__.py
6258 file can now be directly executed by passing their name to the
6259 interpreter. The directory/zipfile is automatically inserted as the
6260 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006262- Issue #1265: Fix a problem with sys.settrace, if the tracing
6263 function uses a generator expression when at the same time the
6264 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006265
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006266- sets and frozensets now have an isdisjoint() method.
6267

6271
Georg Brandl21e99f42010-03-07 15:23:59 +00006272- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006273 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6274 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006275
Georg Brandl3ee81df2008-05-17 18:14:43 +00006276- Issue #1686386: Tuple's tp_repr did not take into account the
6277 possibility of having a self-referential tuple, which is possible
6278 from C code. Nor did object's tp_str consider that a type's tp_str
6279 could do something that could lead to an inifinite recursion.
6280 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6281 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006282
Georg Brandl3ee81df2008-05-17 18:14:43 +00006283- Issue #1164: It was possible to trigger deadlock when using the
6284 'print' statement to write to a file since the GIL was not released
6285 as needed. Now PyObject_Print() does the right thing along with
6286 various tp_print implementations of the built-in types and those in
6287 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006288
Georg Brandl3ee81df2008-05-17 18:14:43 +00006289- Issue #1147: Exceptions were directly allowing string exceptions in
6290 their throw() method even though string exceptions no longer
6291 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00006295
Brett Cannon1e534b52007-09-07 04:18:30 +00006296- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006297 PyObject_Call() never calling back out to Python code to trigger
6298 recursion depth updates/checks. Required the creation of a static
6299 RuntimeError instance in case normalizing an exception put the
6300 recursion check value past its limit. Fixes crashers
6301 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006302
Georg Brandl3ee81df2008-05-17 18:14:43 +00006303- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006316- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006317 __*__ attributes. (Some already existed, e.g., __doc__ and
6318 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006319
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006320- Add -3 option to the interpreter to warn about features that are
6321 deprecated and will be changed/removed in Python 3.0.
6322
Georg Brandl2134e752007-05-21 20:34:16 +00006323- Patch #1686487: you can now pass any mapping after '**' in function
6324 calls.
6325
Collin Winter62903052007-05-18 23:11:24 +00006326- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006327 "except E as target:". This is to provide forwards compatibility
6328 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006335- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006336 setting a plain string, ie don't expand to single letter identifiers.
6337
Raymond Hettinger13936692007-04-11 18:40:58 +00006338- Request #1191699: Slices can now be pickled.
6339
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006340- Request #1193128: str.translate() now allows a None argument for
6341 translations that only remove characters without re-mapping the
6342 remaining characters.
6343
Georg Brandl5cb76c12007-03-21 09:00:39 +00006344- Patch #1682205: a TypeError while unpacking an iterable is no longer
6345 masked by a generic one with the message "unpack non-sequence".
6346
Neal Norwitzaa754b72007-03-21 06:39:48 +00006347- Remove unused file Python/fmod.c.
6348
Guido van Rossum143b5642007-03-23 04:58:42 +00006349- Bug #1683368: The object.__init__() and object.__new__() methods are
6350 now stricter in rejecting excess arguments. The only time when
6351 either allows excess arguments is when it is not overridden and the
6352 other one is. For backwards compatibility, when both are
6353 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006354 warning later). Also, type.__init__() insists on the same signature
6355 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006356
Georg Brandl3ee81df2008-05-17 18:14:43 +00006357- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6358 object to complex using its __complex__() method before falling back
6359 to the __float__() method. Therefore, the functions in the cmath
6360 module now can operate on objects that define a __complex__()
6361 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006362
Georg Brandl3ee81df2008-05-17 18:14:43 +00006363- Patch #1623563: allow __class__ assignment for classes with
6364 __slots__. The old and the new class are still required to have the
6365 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006366

6378
Georg Brandl7b9c5552007-03-12 14:30:05 +00006379- Bug #1678647: write a newline after printing an exception in any
6380 case, even when converting the value to a string failed.
6381
Georg Brandl871f1bc2007-03-12 13:17:36 +00006382- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006383 its argument, if it exists. If not, it will work like before. This
6384 allows customizing the output of dir() in the presence of a
6385 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006386
Collin Winter276887b2007-03-12 16:11:39 +00006387- Patch #922167: Python no longer segfaults when faced with infinitely

Georg Brandl3ee81df2008-05-17 18:14:43 +00006393- Patch #1491866: change the complex() constructor to allow
6394 parthensized forms. This means complex(repr(x)) now works instead of
6395 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006396
Georg Brandlaa2321b2007-03-07 00:40:28 +00006397- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006398 makes the filenames the warning module prints much more sensible
6399 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006400

Georg Brandl0fca97a2007-03-05 22:28:08 +00006412- Patch #1674228: when assigning a slice (old-style), check for the
6413 sq_ass_slice instead of the sq_slice slot.
6414
Georg Brandl3ee81df2008-05-17 18:14:43 +00006415- When printing an unraisable error, don't print exceptions. before
6416 the name. This duplicates the behavior whening normally printing
6417 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006919- Added a timeout parameter to the constructor of other protocols
6920 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6921 work started with create_connection() and timeout in httplib, and
6922 closes patch #723312.
6923
Vinay Sajip8549ce32007-05-06 17:53:37 +00006924- Patch #1676823: Added create_connection() to socket.py, which may be
6925 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006926 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006927

6948
Georg Brandlf66b6032007-03-14 08:27:52 +00006949- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006950 AttributeError instead of an IOError when the server's response
6951 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006952

Georg Brandl3ee81df2008-05-17 18:14:43 +00006957- Patch #1429539: pdb now correctly initializes the __main__ module
6958 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006959 correctly now.
6960

6967
Georg Brandl3ee81df2008-05-17 18:14:43 +00006968- Patch #1530482: add pydoc.render_doc() which returns the

6978 parameter which can be set to False to prevent the default
6979 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00006980
Georg Brandl9e6b4702007-03-13 18:15:41 +00006981- Patch #1581073: add a flag to textwrap that prevents the dropping of
6982 whitespace while wrapping.
6983
Georg Brandl92a6bae2007-03-13 17:43:32 +00006984- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006985 are set for invalid interpolation sequences that would lead to
6986 errors on reading back those values.

7029 returned string up to the first NUL character.
7030

7040
Georg Brandl3ee81df2008-05-17 18:14:43 +00007041- unittest now verifies more of its assumptions. In particular,
7042 TestCase and TestSuite subclasses (not instances) are no longer
7043 accepted in TestSuite.addTest(). This should cause no
7044 incompatibility since it never made sense with ordinary subclasses
7045 -- the failure just occurred later, with a more cumbersome
7046 exception.

7056
Georg Brandl3ee81df2008-05-17 18:14:43 +00007057- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00007435 time so that opening a database previously created with the DB_DUP
7436 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7437 opens. Specifically: dictionary assignment to a DB object will
7438 replace all values for a given key when the database allows
7439 duplicate values. DB users should use DB.put(k, v) when they want
7440 to store duplicates; not DB[k] = v.

7447 characters with ASCII value less than 32. Also, it correctly quotes
7448 dots only if they occur on a single line, as opposed to the previous
7449 behavior of quoting dots if they are the second character of any
7450 line.
