332Core and Builtins
333-----------------
334
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000335- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
336 start byte and the continuation byte(s) are now considered invalid, instead
337 of the number of bytes specified by the start byte.
338 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
339 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
340 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
341 Previous versions returned a single u'\ufffd'.
342
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000343- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000344 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
345 arises from the "Overriding __eq__ blocks inheritance ..." warning
346 when turned into an exception: in this case the exception simply
347 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000348
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000349- Issue #8748: Fix two issues with comparisons between complex and integer
350 objects. (1) The comparison could incorrectly return True in some cases
351 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
352 (2) The comparison raised an OverflowError for large integers, leading
353 to unpredictable exceptions when combining integers and complex objects
354 in sets or dicts.
355
Mark Dickinson81336372010-05-30 12:12:25 +0000356- Issue #5211: Implicit coercion for the complex type is now completely
357 removed. (Coercion for arithmetic operations was already removed in 2.7
358 alpha 4, but coercion for rich comparisons was accidentally left in.)
359
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000360- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
361 and error handler, instead of writing to the C stderr file in utf-8
362
Georg Brandlfee0f442010-05-22 21:26:21 +0000363- Issue #7902: When using explicit relative import syntax, don't try implicit
364 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +0000365
Georg Brandlfee0f442010-05-22 21:26:21 +0000366- Issue #7079: Fix a possible crash when closing a file object while using it
367 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +0000368
Victor Stinnerb65bd2e2010-06-11 19:22:28 +0000369- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +0000370 Window Server again in a framework build on MacOSX 10.5 or earlier.

373-----
374
Georg Brandlfee0f442010-05-22 21:26:21 +0000375- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
376 of the interpreter to set sys.argv without also modifying sys.path. This
377 helps fix `CVE-2008-5983
Antoine Pitrou6a265602010-05-21 17:12:38 +0000378 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

402
R. David Murray52dcd452010-06-02 22:03:15 +0000403- Issue #1368247: set_charset (and therefore MIMEText) now automatically

405
Alexander Belopolsky9292ee02010-05-27 20:55:27 +0000406- Issue #7150: Raise OverflowError if the result of adding or subtracting

494 non-float non-integer argument is now converted to an integer (if possible)
495 using its __int__ method. Previously, only small arguments were treated this

596 the method could block indefinitely if called just before the event loop
597 started running. This also fixes the occasional freezes witnessed in
598 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +0000600- Issue #5103: SSL handshake would ignore the socket timeout and block
601 indefinitely if the other end didn't respond.
602
Georg Brandlfee0f442010-05-22 21:26:21 +0000603- The do_handshake() method of SSL objects now adjusts the blocking mode of the
604 SSL structure if necessary (as other methods already do).

Georg Brandlfee0f442010-05-22 21:26:21 +0000614- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
615 string "python" as the *ident*. openlog() arguments are all optional and
616 keywords.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000696 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
697 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

720
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000721- Issue #7301: Add environment variable $PYTHONWARNINGS.
722
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000723- Issue #8329: Don't return the same lists from select.select when no fds are
724 changed.
725
Georg Brandlfee0f442010-05-22 21:26:21 +0000726- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000727 on 64-bit machines. The shift count for either left or right shift is
728 permitted to be up to sys.maxsize.
729
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000730- Ensure that tokenization of identifiers is not affected by locale.

735
Georg Brandlfee0f442010-05-22 21:26:21 +0000736- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
737 with a non-empty format string. This is an effort to future-proof user
738 code. If a derived class does not currently implement __format__ but later
739 adds its own __format__, it would most likely break user code that had
740 supplied a format string. This will be changed to a DeprecationWaring in
741 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +0000774- Issue #8257: The Decimal construct now accepts a float instance directly,
775 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000776

779
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000780- collections.Counter() now supports a subtract() method.
781
Georg Brandlfee0f442010-05-22 21:26:21 +0000782- The functools module now has a total_ordering() class decorator to simplify
783 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +0000785- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +0000791- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
792 InvalidOperation instead of returning False. (Comparisons involving a quiet
793 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
794 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000795
Georg Brandlfee0f442010-05-22 21:26:21 +0000796- Issue #2531: Comparison operations between floats and Decimal instances now
797 return a result based on the numeric values of the operands; previously they
798 returned an arbitrary result based on the relative ordering of id(float) and
799 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000800
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000801- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000802 argument `-` which tells it to read files to compile from stdin. Each line is
803 read on demand and the named file is compiled immediately. (Original patch by
804 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000813- Comparisons using one of <, <=, >, >= between a complex instance and a
814 Fractions instance now raise TypeError instead of returning True/False. This
815 makes Fraction <=> complex comparisons consistent with int <=> complex, float
816 <=> complex, and complex <=> complex comparisons.

925 the set of integer codes for which it was used differed between native packing
926 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001230 file position when calling `truncate()`. It would previously change the file
1231 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001232 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1235 class used to represent files stored inside an archive. The new
1236 implementation is significantly faster and can be wrapped in a
1237 ``io.BufferedReader`` object for more speedups. It also solves an issue
1238 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1251 encoded string for them. This ensures that the upload and register commands
1252 send the correct values to PyPI without any error.

1327-----------------
1328
Georg Brandlba83f822010-03-14 09:50:54 +00001329- The ``__complex__()`` method is now looked up on the class of instances to
1330 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001331
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001332- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1333 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1334
Mark Dickinson1b34d252010-01-01 17:27:30 +00001335- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001336 DeprecationWarning when passed a float argument where an integer was expected.
1337 These functions and methods now raise TypeError instead. The majority of the
1338 effects of this change are in the extension modules, but some core functions
1339 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1340 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00001341

1351 used to drop the time part of the result.
1352
Georg Brandlba83f822010-03-14 09:50:54 +00001353- Issue #1811: Improve accuracy and cross-platform consistency for true division
1354 of integers: the result of a/b is now correctly rounded for ints a and b (at
1355 least on IEEE 754 platforms), and in particular does not depend on the
1356 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001357
Georg Brandlba83f822010-03-14 09:50:54 +00001358- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1359 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1360 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001363 executables on OSX.
1364
Georg Brandlba83f822010-03-14 09:50:54 +00001365 These executables now work properly with the arch(1) command: ``arch -ppc
1366 python`` will start a universal binary version of python in PPC mode (unlike
1367 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001390 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1391 alternative to cPickle if you care about performance. Patch by Florent

1428 the same as passing no argument.
1429

Georg Brandlba83f822010-03-14 09:50:54 +00001523- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1524 decimal string that's guaranteed to round back to x under correct rounding
1525 (with round-half-to-even rounding mode). Previously it gave a string based on
1526 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1527 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1528 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001530- Issue #7117: On almost all platforms: float-to-string and string-to-float
1531 conversions within Python are now correctly rounded. Places these conversions
1532 occur include: str for floats and complex numbers; the float and complex
1533 constructors; old-style and new-style numeric formatting; serialization and
1534 deserialization of floats and complex numbers using marshal, pickle and json;
1535 parsing of float and imaginary literals in Python code; Decimal-to-float
1536 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001537
Georg Brandlba83f822010-03-14 09:50:54 +00001538 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1539 providing correctly-rounded strtod and dtoa C functions. This code is
1540 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1541 the C compiler. There may be a small number of platforms on which correct
1542 operation of this code cannot be guaranteed, so the code is not used: notably,
1543 this applies to platforms where the C double format is not IEEE 754 binary64,
1544 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1545 and Python's configure script is unable to determine how to change the FPU
1546 precision. On these platforms conversions use the platform strtod and dtoa,

Georg Brandlba83f822010-03-14 09:50:54 +00001549- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1550 uses the correctly-rounded string <-> float conversions described above (when
1551 available), and so produces correctly rounded results that will display nicely
1552 under the float repr. There are two related small changes: (1) round now
1553 accepts any class with an ``__index__()`` method for its second argument (but
1554 no longer accepts floats for the second argument), and (2) an excessively
1555 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1556 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00001773- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00001774 untrackable objects are not tracked by the garbage collector. This can reduce
1775 the size of collections and therefore the garbage collection overhead on
1776 long-running programs, depending on their particular use of datatypes.

1906
Georg Brandlba83f822010-03-14 09:50:54 +00001907- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1908 file objects with closefd=False. The file descriptor is still kept open but
1909 the file object behaves like a closed file. The ``FileIO`` object also got a

1935 this code path is really executed because I cannot move to such directory on
1936 win2k)

1962 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00002779 for *nix machines for negative handles and large int handles. Without this
2780 check it is possible to segfault the interpreter.

Georg Brandlba83f822010-03-14 09:50:54 +00002799 the timestamp in the gzip stream. The default value remains the current time.

3134 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00003136 - If x is not an int, long or float, then packing x will always result in
3137 struct.error. Previously an x with an __int__ method could be packed by
3138 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3139 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3140 neither __int__ nor __long__, TypeError used to be raised (with a
3141 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3142 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00003144 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
3145 argument with an __int__ method can be packed, but use of this feature
3146 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003339- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3340 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3341 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3342 ``printf`` function, whereas PyString_FromFormat has an independent
3343 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003440 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3441 for catch_warnings() also led to an improvement in the raising of a
3442 DeprecationWarning related to warnings.warn_explicit().
3443

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003508What's New in Python 2.6 beta 3?
3509================================
3510
Barry Warsaw07a4a382008-08-21 01:15:08 +00003511*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003512
3513Core and Builtins
3514-----------------
3515
Guido van Rossumf8402962008-08-20 15:01:50 +00003516- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3517 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3518 extensions do not automatically benefit from the class attribute
3519 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3520 to their tp_flags field if they care. This is a backwards
3521 compatibility feature; in 3.0, all types will use the cache by
3522 default.
3523
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003524- Keyword arguments can now follow starred arguments. (``f(a, *args,
3525 keyword=23)`` is now valid syntax.)
3526
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003527- ctypes function pointers that are COM methods have a boolean True
3528 value again.
3529
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003530- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3531 by denying s# to parse objects that have a releasebuffer procedure,
3532 and introducing s*.
3533
Georg Brandl1e13ea92008-08-11 09:07:59 +00003534- Issue #3537: Fix an assertion failure when an empty but presized dict
3535 object was stored in the freelist.
3536
Mark Dickinsonb6467572008-08-04 21:30:09 +00003537- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3538 ValueError consistently across platforms.
3539
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003540- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3541 (64bit Unix, for example), unichr() would truncate its argument and return
3542 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3543
Neal Norwitze7d8be82008-07-31 17:17:14 +00003544- Apply security patches from Apple.
3545
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003546- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3547 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3548
Antoine Pitrou92f82162008-07-25 22:22:08 +00003549- Issue #1819: function calls with several named parameters are now on
3550 average 35% faster (as measured by pybench).
3551
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003552- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3553 the python debugger steps into a class statement: the free variables (local
3554 variables defined in an outer scope) would be deleted from the outer scope.
3555
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003556- Issue #2620: Overflow checking when allocating or reallocating memory
3557 was not always being done properly in some python types and extension
3558 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3559 all been updated to perform better checks and places in the code that
3560 would previously leak memory on the error path when such an allocation
3561 failed have been fixed.

3564-------
3565
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003566- Issue #3612: Added some missing basic types in ctypes.wintypes.
3567
Benjamin Petersone977ad42008-08-20 01:42:01 +00003568- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3569 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3570
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003571- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3572 version reported by these tools does not necessarily follow the python
3573 version numbering scheme, so the module is less strict when parsing it.
3574
Nick Coghlanf70385a2008-08-18 12:42:46 +00003575- Issue #2235: Added Py3k warnings for types which will become unhashable
3576 under the stricter __hash__ inheritance rules in 3.0. Several types
3577 which did not meet the rules for hash invariants and were already
3578 unhashable in 3.0 have now been explicitly flagged as unhashable in
3579 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3580 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3581
Brett Cannon88f801d2008-08-18 00:46:22 +00003582- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3590
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003591- Issue #3575: Incremental decoder's decode function now takes bytearray
3592 by using 's*' instead of 't#'.
3593
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003594- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003595 fails unicode conversion on 2nd parameter. (windows only)
3596
Georg Brandl222e2082010-08-01 22:27:39 +00003597- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003598 in a redirect.
3599
Brett Cannonabe423e2008-08-16 21:47:07 +00003600- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003601 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003602
Facundo Batistaeb90b782008-08-16 14:44:07 +00003603- Issue #2776: fixed small issue when handling an URL with double slash
3604 after a 302 response in the case of not going through a proxy.
3605
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003606- Issue #2676: in the email package, content-type parsing was hanging on
3607 pathological input because of quadratic or exponential behaviour of a
3608 regular expression.
3609
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003610- Issue #3476: binary buffered reading through the new "io" library is now
3611 thread-safe.
3612
Brett Cannonbf3157b2008-08-14 05:00:03 +00003613- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3614 since mimetools itself is deprecated. Because modules are cached, all
3615 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3616
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003617- Issue #3134: shutil referenced undefined WindowsError symbol.
3618
Robert Schuppenies14646332008-08-10 11:01:53 +00003619- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3620 menu entries were not deleted.
3621
Brett Cannon83e81842008-08-09 23:30:55 +00003622- Copied the implementation of reduce() to _functools.reduce() to have a
3623 version that did not raise a DeprecationWarning under -3.
3624
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003625- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3626 a MemoryError rather than silently stop the iteration.
3627
Guido van Rossum59ce9012008-08-09 14:55:34 +00003628- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3629 to _sre.compile() will now be rejected. This should not affect anybody
3630 since the re.compile() function never generates invalid re-bytecode.
3631
Skip Montanaroa032bf42008-08-08 22:52:51 +00003632- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3633 upon first access it can be automatically initialized from the csv file if
3634 it wasn't initialized during instantiation.
3635
Brett Cannon3aa2a492008-08-06 22:28:09 +00003636- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3637 the reload() built-in has been removed.
3638
Brett Cannon7e30b672008-08-04 21:52:25 +00003639- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003640 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003651 asking for a specific length. This problem only affected files opened
3652 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003653

Nick Coghlan6e8fef02008-08-18 13:14:22 +00003693- Issue #2235: the C API function PyObject_HashNotImplemented and its
3694 interaction with the tp_hash slot (added in 2.6b2) are now documented
3695
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003696- Issue #643841: The language reference now provides more detailed
3697 coverage of the lookup process for special methods. The disclaimers
3698 regarding lack of coverage of new-style classes have also been
3699 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003702What's New in Python 2.6 beta 2?
3703================================
3704
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003705*Release date: 17-Jul-2008*
3706
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003707Core and Builtins
3708-----------------
3709
Georg Brandl3e483f62008-07-16 22:57:41 +00003710- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3711 its methods now allow for items objects that can be converted to
3712 an integer using operator.index().
3713
Mark Dickinson64b7e502008-07-16 09:40:03 +00003714- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3715 produced a ValueError instead of giving the correct float.
3716
Eric Smitha5fa5a22008-07-16 00:11:49 +00003717- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3718 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3719
Mark Dickinson7103aa42008-07-15 19:08:33 +00003720- Issue #3008: the float type has a new instance method 'float.hex'
3721 and a new class method 'float.fromhex' to convert floating-point
3722 numbers to and from hexadecimal strings, respectively.
3723
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003724- Issue #2235: __hash__ is once again inherited by default. To allow
3725 collections.Hashable to remain meaningful in the presence of the
3726 default hash implementation (object.__hash__), it is now possible
3727 to explicit block inheritance of hash by setting __hash__=None at
3728 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3729 level.
3730
Nick Coghlanb028f502008-07-13 14:52:36 +00003731- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3732 the parent module cannot be found while performing an absolute import.
3733 This means that an incorrectly defined __package__ attribute will
3734 now only prevent relative imports in that module rather than causing
3735 all imports from that module to fail.
3736
Nick Coghlan14ff9942008-07-08 14:21:42 +00003737- Issue #2517: Allow unicode messages in Exceptions again by correctly
3738 bypassing the instance dictionary when looking up __unicode__ on
3739 new-style classes.
3740
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003741- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3742 set to a custom object whose write() method happens to install
3743 another file in sys.stdout.
3744
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003745- Issue #3088: Corrected a race condition in classes derived from
3746 threading.local: the first member set by a thread could be saved in
3747 another thread's dictionary.
3748
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003749- Issue #3004: Minor change to slice.indices(): the start and stop
3750 arguments are now treated identically, making the behaviour easier
3751 to describe and understand. For example, slice(None, -10,
3752 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3753 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3754 10, -1).
3755
Georg Brandl278fc502008-07-19 12:46:12 +00003756- Issue #3219: Calling a function with repeated keyword arguments,
3757 f(a=2, a=23), would not cause a syntax error. This was a regression
3758 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003759
Georg Brandl278fc502008-07-19 12:46:12 +00003760- Issue #2862: Make int and float freelist management consistent with
3761 other freelists. Changes their CompactFreeList apis into
3762 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00003763

3765-------
3766
Thomas Heller57adf222008-08-14 19:10:48 +00003767- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3768 api functions without holding the GIL, which could lead to a fatal
3769 error when they failed.
3770
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003771- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003779- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3780 ForkingPickler.register() to resolve conflict with ctypes.
3781
Vinay Sajip51e65192008-07-18 09:01:10 +00003782- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00003783
Thomas Heller880f5292008-07-15 19:39:38 +00003784- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3785 a valid dlerror() message.
3786
Thomas Heller2bad6572008-07-15 17:19:50 +00003787- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3788 incomplete structure was created.
3789
Brett Cannon3d0b9f02008-07-13 01:15:07 +00003790- Issue #3339: dummy_thread.acquire() should not return None.
3791
Raymond Hettingerb01713e2008-07-10 14:34:57 +00003792- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
3793
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003794- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00003795
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003796- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3797 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003798 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003799 content-length. The problem had been corrected in the 2.4 branch, but never
3800 merged into trunk.
3801
Georg Brandle78fbcc2008-07-05 10:13:36 +00003802- Issue #2663: add filtering capability to shutil.copytree().

3805
3806- Issue #1526: Allow more than 64k files to be added to Zip64 file.
3807
3808- Issue #1746: Correct handling of zipfile archive comments (previously
3809 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00003810 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00003811
Vinay Sajip51e65192008-07-18 09:01:10 +00003812- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003813 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00003814
Nick Coghlanc060b0e2008-07-02 13:09:19 +00003815- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3816 handling is now the same as that of other special attributes like __name__).
3817
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003818- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3819 removal in Python 3.0 in favor of urllib2.urlopen().

3831
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00003832- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00004270- Issue #1631171: Re-implement the 'warnings' module in C (the
4271 original Python code has been kept as backup). This will allow for
4272 using the 'warning's machinery in such places as the parser where
4273 use of pure Python code is not possible. Both the ``showarning()``
4274 and ``formatwarning()`` gain an optional 'line' argument which is
4275 not called by default for backwards-compatibility reasons. Setting
4276 ``warnings.showwarning()`` to an implementation that lacks support
4277 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004340- Issue #2550: The approach used by client/server code for obtaining
4341 ports to listen on in network-oriented tests has been refined in an
4342 effort to facilitate running multiple instances of the entire
4343 regression test suite in parallel without issue.
4344 test_support.bind_port() has been fixed such that it will always
4345 return a unique port -- which wasn't always the case with the
4346 previous implementation, especially if socket options had been set
4347 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4348 new implementation of bind_port() will actually raise an exception
4349 if it is passed an AF_INET/SOCK_STREAM socket with either the
4350 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4351 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4352 the socket it's been passed. This currently only applies to
4353 Windows. This option prevents any other sockets from binding to the
4354 host/port we've bound to, thus removing the possibility of the
4355 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4356 when a second SOCK_STREAM socket binds and accepts to a host/port
4357 that's already been bound by another socket. The optional preferred
4358 port parameter to bind_port() has been removed. Under no
4359 circumstances should tests be hard coding ports!
4360
4361 test_support.find_unused_port() has also been introduced, which will
4362 pass a temporary socket object to bind_port() in order to obtain an
4363 unused port. The temporary socket object is then closed and
4364 deleted, and the port is returned. This method should only be used
4365 for obtaining an unused port in order to pass to an external program
4366 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4367 a parameter to a server-oriented class that doesn't give you direct
4368 access to the underlying socket used.
4369
4370 Finally, test_support.HOST has been introduced, which should be used
4371 for the host argument of any relevant socket calls (i.e. bind and
4372 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004373
4374 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004375 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004376 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4377 test_asynchat and test_socket_ssl.
4378
Georg Brandl3ee81df2008-05-17 18:14:43 +00004379 It is now possible for multiple instances of the regression test
4380 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004659- Added the future_builtins module, which contains hex() and oct().
4660 These are the PEP 3127 version of these functions, designed to be
4661 compatible with the hex() and oct() builtins from Python 3.0. They
4662 differ slightly in their output formats from the existing, unchanged
4663 Python 2.6 builtins. The expected usage of the future_builtins
4664 module is:
4665 from future_builtins import hex, oct
4666
Eric Smith7ef40bf2008-02-20 23:34:22 +00004667- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4668 exponents for exponents with absolute value < 100. Follows C99
4669 standard. This is a change on Windows, which would use 3 digits.
4670 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4671 so that any alterations it does to the resulting string will be
4672 available in stringlib/formatter.h (for float.__format__).
4673
Eric Smith5a3c1352008-02-19 13:21:56 +00004674- Implemented PEP 3101, Advanced String Formatting. This adds a new
4675 builtin format(); a format() method for str and unicode; a
4676 __format__() method to object, str, unicode, int, long, float, and
4677 datetime; the class string.Formatter; and the C API
4678 PyObject_Format().
4679
Georg Brandl3ee81df2008-05-17 18:14:43 +00004680- Fixed several potential crashes, all caused by specially crafted
4681 __del__ methods exploiting objects in temporarily inconsistent
4682 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004683
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004684- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004685 prevent a possible crash: an Abstract Base Class would try to access
4686 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004687
Georg Brandl3ee81df2008-05-17 18:14:43 +00004688- Fixed repr() and str() of complex numbers with infinity or nan as
4689 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004691- Clear all free lists during a gc.collect() of the highest generation
4692 in order to allow pymalloc to free more arenas. Python may give back
4693 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004694
Georg Brandl3ee81df2008-05-17 18:14:43 +00004695- Issue #2045: Fix an infinite recursion triggered when printing a
4696 subclass of collections.defaultdict, if its default_factory is set
4697 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004698
Christian Heimesf75dbef2008-02-08 00:11:31 +00004699- Fixed a minor memory leak in dictobject.c. The content of the free
4700 list was not freed on interpreter shutdown.
4701
Georg Brandl21e99f42010-03-07 15:23:59 +00004702- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004703 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004704
Georg Brandl3ee81df2008-05-17 18:14:43 +00004705- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4706 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004707 to compact the internal free lists of pre-allocted ints and floats.
4708
Georg Brandl3ee81df2008-05-17 18:14:43 +00004709- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4710 calls. Python expected the return type int but the fork familie
4711 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004712
Georg Brandl3ee81df2008-05-17 18:14:43 +00004713- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4714 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004715
Georg Brandl3ee81df2008-05-17 18:14:43 +00004716- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4717 with the collections.Sequence API.

4723 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004724
Georg Brandl3ee81df2008-05-17 18:14:43 +00004725- Patch #1473257: generator objects gain a gi_code attribute. This is
4726 the same object as the func_code attribute of the function that
4727 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004728
Georg Brandl3ee81df2008-05-17 18:14:43 +00004729- Issue #1920: "while 0" statements were completely removed by the
4730 compiler, even in the presence of an "else" clause, which is
4731 supposed to be run when the condition is false. Now the compiler
4732 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004733
Guido van Rossumeead05f2008-01-24 18:21:02 +00004734- A few crashers fixed: weakref_in_del.py (issue #1377858);
4735 loosing_dict_ref.py (issue #1303614, test67.py);
4736 borrowed_ref_[34].py (not in tracker).
4737

4741
Georg Brandl3ee81df2008-05-17 18:14:43 +00004742- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004743 several extension methods and modules do not work without unicode
4744 support.
4745
Georg Brandl26543b12008-01-21 18:36:51 +00004746- Issue #1882: when compiling code from a string, encoding cookies in the

4748
Georg Brandl14404b62008-01-19 19:27:05 +00004749- Issue #1679: "0x" was taken as a valid integer literal.
4750
Georg Brandl6caad7d2008-01-26 14:19:22 +00004751- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004752 added.
4753
Christian Heimesc94e2b52008-01-14 04:13:37 +00004754- sys.float_info / PyFloat_GetInfo: The floating point information
4755 object was converted from a dict to a specialized structseq object.
4756
Georg Brandl3ee81df2008-05-17 18:14:43 +00004757- Patch #1816: Added sys.flags structseq. It exposes the status of
4758 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004759
Georg Brandl3ee81df2008-05-17 18:14:43 +00004760- Objects/structseq.c: Implemented new structseq representation. The
4761 patch makes structseqs (e.g. the return value of os.stat) more
4762 readable.

Georg Brandlaed6c662008-01-07 17:25:53 +00004770- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4771
Georg Brandl3ee81df2008-05-17 18:14:43 +00004772- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4773 envvar and sys.dont_write_bytecode attribute. All these can be set
4774 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004776- Improve some exception messages when Windows fails to load an
4777 extension module. Now we get for example '%1 is not a valid Win32
4778 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004785- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004786 and INF. float("nan"), float("inf") and float("-inf") now work on
4787 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004789- Compiler now generates simpler and faster code for dictionary
4790 literals. The oparg for BUILD_MAP now indicates an estimated
4791 dictionary size. There is a new opcode, STORE_MAP, for adding
4792 entries to the dictionary.

4822 file can now be directly executed by passing their name to the
4823 interpreter. The directory/zipfile is automatically inserted as the
4824 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004826- Issue #1265: Fix a problem with sys.settrace, if the tracing
4827 function uses a generator expression when at the same time the
4828 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004829

4835
Georg Brandl21e99f42010-03-07 15:23:59 +00004836- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004837 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4838 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004839
Georg Brandl3ee81df2008-05-17 18:14:43 +00004840- Issue #1686386: Tuple's tp_repr did not take into account the
4841 possibility of having a self-referential tuple, which is possible
4842 from C code. Nor did object's tp_str consider that a type's tp_str
4843 could do something that could lead to an inifinite recursion.
4844 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4845 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004846
Georg Brandl3ee81df2008-05-17 18:14:43 +00004847- Issue #1164: It was possible to trigger deadlock when using the
4848 'print' statement to write to a file since the GIL was not released
4849 as needed. Now PyObject_Print() does the right thing along with
4850 various tp_print implementations of the built-in types and those in
4851 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004852
Georg Brandl3ee81df2008-05-17 18:14:43 +00004853- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00004859
Brett Cannon1e534b52007-09-07 04:18:30 +00004860- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861 PyObject_Call() never calling back out to Python code to trigger
4862 recursion depth updates/checks. Required the creation of a static
4863 RuntimeError instance in case normalizing an exception put the
4864 recursion check value past its limit. Fixes crashers
4865 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004866

Neal Norwitz0ac60192007-05-27 04:08:54 +00004880- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004881 __*__ attributes. (Some already existed, e.g., __doc__ and
4882 __name__.)

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004884- Add -3 option to the interpreter to warn about features that are
4885 deprecated and will be changed/removed in Python 3.0.
4886
Georg Brandl2134e752007-05-21 20:34:16 +00004887- Patch #1686487: you can now pass any mapping after '**' in function
4888 calls.
4889
Collin Winter62903052007-05-18 23:11:24 +00004890- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004891 "except E as target:". This is to provide forwards compatibility
4892 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004899- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004900 setting a plain string, ie don't expand to single letter identifiers.
4901
Raymond Hettinger13936692007-04-11 18:40:58 +00004902- Request #1191699: Slices can now be pickled.
4903
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004904- Request #1193128: str.translate() now allows a None argument for
4905 translations that only remove characters without re-mapping the
4906 remaining characters.
4907
Georg Brandl5cb76c12007-03-21 09:00:39 +00004908- Patch #1682205: a TypeError while unpacking an iterable is no longer

4912
Guido van Rossum143b5642007-03-23 04:58:42 +00004913- Bug #1683368: The object.__init__() and object.__new__() methods are
4914 now stricter in rejecting excess arguments. The only time when
4915 either allows excess arguments is when it is not overridden and the
4916 other one is. For backwards compatibility, when both are
4917 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004918 warning later). Also, type.__init__() insists on the same signature
4919 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004920
Georg Brandl3ee81df2008-05-17 18:14:43 +00004921- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4922 object to complex using its __complex__() method before falling back
4923 to the __float__() method. Therefore, the functions in the cmath
4924 module now can operate on objects that define a __complex__()
4925 method.

4929 same slot names.

4942
Georg Brandl7b9c5552007-03-12 14:30:05 +00004943- Bug #1678647: write a newline after printing an exception in any
4944 case, even when converting the value to a string failed.
4945
Georg Brandl871f1bc2007-03-12 13:17:36 +00004946- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004947 its argument, if it exists. If not, it will work like before. This
4948 allows customizing the output of dir() in the presence of a
4949 __getattr__().

4958 parthensized forms. This means complex(repr(x)) now works instead of
4959 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004960
Georg Brandlaa2321b2007-03-07 00:40:28 +00004961- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004962 makes the filenames the warning module prints much more sensible
4963 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004976- Patch #1674228: when assigning a slice (old-style), check for the
4977 sq_ass_slice instead of the sq_slice slot.
4978
Georg Brandl3ee81df2008-05-17 18:14:43 +00004979- When printing an unraisable error, don't print exceptions. before
4980 the name. This duplicates the behavior whening normally printing
4981 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005514 AttributeError instead of an IOError when the server's response
5515 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005516

Georg Brandl3ee81df2008-05-17 18:14:43 +00005532- Patch #1530482: add pydoc.render_doc() which returns the

5547
Georg Brandl92a6bae2007-03-13 17:43:32 +00005548- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005549 are set for invalid interpolation sequences that would lead to
5550 errors on reading back those values.

5593 returned string up to the first NUL character.

5604
Georg Brandl3ee81df2008-05-17 18:14:43 +00005605- unittest now verifies more of its assumptions. In particular,
5606 TestCase and TestSuite subclasses (not instances) are no longer
5607 accepted in TestSuite.addTest(). This should cause no
5608 incompatibility since it never made sense with ordinary subclasses
5609 -- the failure just occurred later, with a more cumbersome
5610 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005999 time so that opening a database previously created with the DB_DUP
6000 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6001 opens. Specifically: dictionary assignment to a DB object will
6002 replace all values for a given key when the database allows
6003 duplicate values. DB users should use DB.put(k, v) when they want
6004 to store duplicates; not DB[k] = v.

6011 characters with ASCII value less than 32. Also, it correctly quotes
6012 dots only if they occur on a single line, as opposed to the previous
6013 behavior of quoting dots if they are the second character of any
6014 line.

6360 of w# format code incorrectly truncated the length to an int, even
6361 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6362 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006392- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6393 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
