Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000406- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
407 start byte and the continuation byte(s) are now considered invalid, instead
408 of the number of bytes specified by the start byte.
409 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
410 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
411 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

422 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

808 with a non-empty format string. This is an effort to future-proof user
809 code. If a derived class does not currently implement __format__ but later
810 adds its own __format__, it would most likely break user code that had
811 supplied a format string. This will be changed to a DeprecationWaring in
812 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +0000845- Issue #8257: The Decimal construct now accepts a float instance directly,
846 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000847
848 >>> Decimal(1.1)
849 Decimal('1.100000000000000088817841970012523233890533447265625')
850

Georg Brandlfee0f442010-05-22 21:26:21 +0000862- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
863 InvalidOperation instead of returning False. (Comparisons involving a quiet
864 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
865 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000866
Georg Brandlfee0f442010-05-22 21:26:21 +0000867- Issue #2531: Comparison operations between floats and Decimal instances now
868 return a result based on the numeric values of the operands; previously they
869 returned an arbitrary result based on the relative ordering of id(float) and
870 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000871
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000872- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000873 argument `-` which tells it to read files to compile from stdin. Each line is
874 read on demand and the named file is compiled immediately. (Original patch by
875 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000884- Comparisons using one of <, <=, >, >= between a complex instance and a
885 Fractions instance now raise TypeError instead of returning True/False. This
886 makes Fraction <=> complex comparisons consistent with int <=> complex, float
887 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +0000991- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
992 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +0000994 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
995 inconsistent: __int__ was used for some integer codes but not for others, and
996 the set of integer codes for which it was used differed between native packing
997 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001301 file position when calling `truncate()`. It would previously change the file
1302 position to the given argument, which goes against the tradition of

1306 class used to represent files stored inside an archive. The new
1307 implementation is significantly faster and can be wrapped in a

Georg Brandlba83f822010-03-14 09:50:54 +00001400- The ``__complex__()`` method is now looked up on the class of instances to
1401 make it consistent with other special methods.

1405
Mark Dickinson1b34d252010-01-01 17:27:30 +00001406- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001407 DeprecationWarning when passed a float argument where an integer was expected.
1408 These functions and methods now raise TypeError instead. The majority of the
1409 effects of this change are in the extension modules, but some core functions
1410 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1411 and many unicode/str methods.

1425 of integers: the result of a/b is now correctly rounded for ints a and b (at
1426 least on IEEE 754 platforms), and in particular does not depend on the
1427 internal representation of a long.

1435
Georg Brandlba83f822010-03-14 09:50:54 +00001436 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001576- Issue #3382: 'F' formatting for float and complex now convert the result to
1577 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1578 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001579
Georg Brandlba83f822010-03-14 09:50:54 +00001580- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1581 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001582
Georg Brandlba83f822010-03-14 09:50:54 +00001583- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1584 1e-100 used to raise OverflowError, but now gives the requested 120
1585 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001593
Georg Brandlba83f822010-03-14 09:50:54 +00001594- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1595 decimal string that's guaranteed to round back to x under correct rounding
1596 (with round-half-to-even rounding mode). Previously it gave a string based on
1597 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1598 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1599 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001600
Georg Brandlba83f822010-03-14 09:50:54 +00001601- Issue #7117: On almost all platforms: float-to-string and string-to-float
1602 conversions within Python are now correctly rounded. Places these conversions
1603 occur include: str for floats and complex numbers; the float and complex
1604 constructors; old-style and new-style numeric formatting; serialization and
1605 deserialization of floats and complex numbers using marshal, pickle and json;
1606 parsing of float and imaginary literals in Python code; Decimal-to-float
1607 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001608
Georg Brandlba83f822010-03-14 09:50:54 +00001609 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1610 providing correctly-rounded strtod and dtoa C functions. This code is
1611 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1612 the C compiler. There may be a small number of platforms on which correct
1613 operation of this code cannot be guaranteed, so the code is not used: notably,
1614 this applies to platforms where the C double format is not IEEE 754 binary64,
1615 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1616 and Python's configure script is unable to determine how to change the FPU
1617 precision. On these platforms conversions use the platform strtod and dtoa,
1618 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001619
Georg Brandlba83f822010-03-14 09:50:54 +00001620- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1621 uses the correctly-rounded string <-> float conversions described above (when
1622 available), and so produces correctly rounded results that will display nicely
1623 under the float repr. There are two related small changes: (1) round now
1624 accepts any class with an ``__index__()`` method for its second argument (but
1625 no longer accepts floats for the second argument), and (2) an excessively
1626 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1627 raises an exception.

1854 internal representation of integers, for performance reasons. Base 2**30 is
1855 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00001920- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1921 existing .py counterpart, override the co_filename attributes of all code
1922 objects if the original filename is obsolete (which can happen if the file has

3407
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003408- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3409
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003410- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3411 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3412 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3413 ``printf`` function, whereas PyString_FromFormat has an independent
3414 implementation and uses "%zd" on all platforms for size_t values.
3415 This makes a difference on win64, where ``printf`` needs "%Id" to display
3416 64bit values.
3417
Benjamin Peterson97179b02008-09-09 20:55:01 +00003418- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3419 error.
3420
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003421- Issue #3777: long() applied to a float object now always return a long
3422 object; previously an int would be returned for small values. the __long__
3423 method is allowed to return either an int or a long, but the behaviour of
3424 float objects should not change to respect backward compatibility.
3425
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003426- Issue #3751: str.rpartition would perform a left-partition when called with
3427 a unicode argument.
3428
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003429- Issue #3683: Fix compilation when --without-threads is given.
3430
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003431- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003432 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003433 was correctly parsed but parsing of subsequent arguments failed.
3434
Vinay Sajip35e3b032008-09-01 14:33:59 +00003435- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003436 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3437 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3438 when given a tuple of classes as second argument, were looking up
3439 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3440 type object.
3441
Neal Norwitz18aa3882008-08-24 05:04:52 +00003442- Fix crashes on memory allocation failure found with failmalloc.
3443
3444- Fix memory leaks found with valgrind and update suppressions file.
3445
3446- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3447
3448- Fix problem using wrong name in decimal module reported by pychecker.
3449
Christian Heimes7d4c3172008-08-22 19:47:25 +00003450- Silenced another compiler warning about a used but not defined
3451 function 'stringlib_contains_obj'.
3452
Benjamin Peterson712ee922008-08-24 18:10:20 +00003453- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3454 ``__delslice__``.
3455
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003456- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3457 library targets in the Makefile.
3458
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003459- Issue #1204: The configure script now tests for additional libraries
3460 that may be required when linking against readline. This fixes issues
3461 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
3462
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00003463C-API
3464-----
3465
3466- Aliased PyObject_Bytes to PyObject_Str.

3470
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00003471- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
3472 stack usage in the case of deeply nested objects.
3473
Guido van Rossume3c4fd92008-09-10 14:27:00 +00003474- Issue #3629: Fix sre "bytecode" validator for an end case.
3475
Martin v. Löwis24329ba2008-09-10 13:38:12 +00003476- Issue #3811: The Unicode database was updated to 5.1.
3477
Nick Coghland2e09382008-09-11 12:11:06 +00003478- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
3479 silent misbehaviour when a single instance is nested in multiple
3480 with statements, or when the methods are invoked in the wrong order.
3481
Vinay Sajip844f7412008-09-09 13:42:08 +00003482- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
3483
Nick Coghland2e09382008-09-11 12:11:06 +00003484- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003485 return a list or None rather than a custom object.
3486
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003487- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3488
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003489- Issue #3535: zipfile couldn't read some zip files larger than 2GB.
3490
3491- Issue #3776: Deprecate the bsddb package for removal in 3.0.
Brett Cannon32476fc2008-09-05 18:33:51 +00003492
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +00003493- Issue #3762: platform.architecture() fails if python is lanched via
3494 its symbolic link.
3495
Vinay Sajip65d66e12008-09-04 07:31:21 +00003496- Issue #3772: Fixed regression problem in StreamHandler.emit().

3508 path to the Python binary.
3509
Georg Brandl222e2082010-08-01 22:27:39 +00003510- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00003511 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3512 for catch_warnings() also led to an improvement in the raising of a
3513 DeprecationWarning related to warnings.warn_explicit().
3514
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003515- The deprecation warnings for the old camelCase threading API were removed.
3516
Vinay Sajip35e3b032008-09-01 14:33:59 +00003517- logging: fixed lack of use of encoding attribute specified on a stream.
3518
Christian Heimesa27a62e2008-08-22 19:55:54 +00003519- Silenced a trivial compiler warning in the sqlite module.
3520
Christian Heimes1cc69632008-08-22 20:10:27 +00003521- Fixed two format strings in the _collections module.
3522
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003523- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
3524 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00003525
Gregory P. Smithd7122032008-09-02 05:36:11 +00003526- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
3527 non-integer floating point number.
3528
Vinay Sajip65d66e12008-09-04 07:31:21 +00003529- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

3534
Jesse Noller438195f2009-01-18 21:04:36 +00003535- Issue #4301: Patch the logging module to add processName support, remove
3536 _check_logger_class from multiprocessing.
3537
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003538- Issue #2975: When compiling several extension modules with Visual Studio 2008
3539 from the same python interpreter, some environment variables would grow
3540 without limit.
3541
Benjamin Peterson37346b22008-08-23 20:27:43 +00003542- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3543 exploitation of poor argument checking.
3544
Gerhard Häringef2276b2008-09-12 13:54:06 +00003545- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3546
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003547- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3548 remaining ones have "pysqlite_" prefix.
3549
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003550- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

3556
Nick Coghland2e09382008-09-11 12:11:06 +00003557- Issue #3781: Add test.test_support.check_warnings() as a convenience
3558 wrapper for warnings.catch_warnings() that makes it easier to check
3559 that expected warning messages are being reported.
3560
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003561- Issue #3796: Some tests functions were not enabled in test_float.
3562
3563- Issue #3768: Move test_py3kwarn over to the new API for catch_warnings().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003579What's New in Python 2.6 beta 3?
3580================================
3581
Barry Warsaw07a4a382008-08-21 01:15:08 +00003582*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003583
3584Core and Builtins
3585-----------------
3586
Guido van Rossumf8402962008-08-20 15:01:50 +00003587- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3588 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3589 extensions do not automatically benefit from the class attribute
3590 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3591 to their tp_flags field if they care. This is a backwards
3592 compatibility feature; in 3.0, all types will use the cache by
3593 default.
3594
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003595- Keyword arguments can now follow starred arguments. (``f(a, *args,
3596 keyword=23)`` is now valid syntax.)
3597
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003598- ctypes function pointers that are COM methods have a boolean True
3599 value again.
3600
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003601- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3602 by denying s# to parse objects that have a releasebuffer procedure,
3603 and introducing s*.
3604
Georg Brandl1e13ea92008-08-11 09:07:59 +00003605- Issue #3537: Fix an assertion failure when an empty but presized dict
3606 object was stored in the freelist.
3607
Mark Dickinsonb6467572008-08-04 21:30:09 +00003608- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3609 ValueError consistently across platforms.
3610
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003611- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3612 (64bit Unix, for example), unichr() would truncate its argument and return
3613 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3614
Neal Norwitze7d8be82008-07-31 17:17:14 +00003615- Apply security patches from Apple.
3616
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003617- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3618 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3619
Antoine Pitrou92f82162008-07-25 22:22:08 +00003620- Issue #1819: function calls with several named parameters are now on
3621 average 35% faster (as measured by pybench).
3622
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003623- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3624 the python debugger steps into a class statement: the free variables (local
3625 variables defined in an outer scope) would be deleted from the outer scope.
3626
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003627- Issue #2620: Overflow checking when allocating or reallocating memory
3628 was not always being done properly in some python types and extension
3629 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3630 all been updated to perform better checks and places in the code that
3631 would previously leak memory on the error path when such an allocation
3632 failed have been fixed.
3633
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003634Library
3635-------
3636
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003637- Issue #3612: Added some missing basic types in ctypes.wintypes.
3638
Benjamin Petersone977ad42008-08-20 01:42:01 +00003639- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3640 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3641
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003642- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3643 version reported by these tools does not necessarily follow the python
3644 version numbering scheme, so the module is less strict when parsing it.
3645
Nick Coghlanf70385a2008-08-18 12:42:46 +00003646- Issue #2235: Added Py3k warnings for types which will become unhashable
3647 under the stricter __hash__ inheritance rules in 3.0. Several types
3648 which did not meet the rules for hash invariants and were already
3649 unhashable in 3.0 have now been explicitly flagged as unhashable in
3650 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3651 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3652
Brett Cannon88f801d2008-08-18 00:46:22 +00003653- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3654 imported into the module but exposed as part of the module's API.
3655
Brett Cannon7b96f072008-08-18 00:41:11 +00003656- Remove an unneeded import of abc.ABCMeta from 'inspect'.

3661
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003662- Issue #3575: Incremental decoder's decode function now takes bytearray
3663 by using 's*' instead of 't#'.
3664
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003665- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003666 fails unicode conversion on 2nd parameter. (windows only)
3667
Georg Brandl222e2082010-08-01 22:27:39 +00003668- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003669 in a redirect.
3670
Brett Cannonabe423e2008-08-16 21:47:07 +00003671- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003672 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003673
Facundo Batistaeb90b782008-08-16 14:44:07 +00003674- Issue #2776: fixed small issue when handling an URL with double slash
3675 after a 302 response in the case of not going through a proxy.
3676
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003677- Issue #2676: in the email package, content-type parsing was hanging on
3678 pathological input because of quadratic or exponential behaviour of a
3679 regular expression.
3680
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003681- Issue #3476: binary buffered reading through the new "io" library is now
3682 thread-safe.
3683
Brett Cannonbf3157b2008-08-14 05:00:03 +00003684- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3685 since mimetools itself is deprecated. Because modules are cached, all
3686 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3687
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003688- Issue #3134: shutil referenced undefined WindowsError symbol.
3689
Robert Schuppenies14646332008-08-10 11:01:53 +00003690- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3691 menu entries were not deleted.

Antoine Pitroude781a42008-08-09 12:43:23 +00003722 asking for a specific length. This problem only affected files opened

3766
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003767- Issue #643841: The language reference now provides more detailed

3779-----------------
3780
Georg Brandl3e483f62008-07-16 22:57:41 +00003781- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3782 its methods now allow for items objects that can be converted to
3783 an integer using operator.index().
3784
Mark Dickinson64b7e502008-07-16 09:40:03 +00003785- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3786 produced a ValueError instead of giving the correct float.
3787
Eric Smitha5fa5a22008-07-16 00:11:49 +00003788- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3789 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3790
Mark Dickinson7103aa42008-07-15 19:08:33 +00003791- Issue #3008: the float type has a new instance method 'float.hex'
3792 and a new class method 'float.fromhex' to convert floating-point
3793 numbers to and from hexadecimal strings, respectively.
3794
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003795- Issue #2235: __hash__ is once again inherited by default. To allow
3796 collections.Hashable to remain meaningful in the presence of the
3797 default hash implementation (object.__hash__), it is now possible
3798 to explicit block inheritance of hash by setting __hash__=None at
3799 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3800 level.
3801
Nick Coghlanb028f502008-07-13 14:52:36 +00003802- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3803 the parent module cannot be found while performing an absolute import.
3804 This means that an incorrectly defined __package__ attribute will
3805 now only prevent relative imports in that module rather than causing
3806 all imports from that module to fail.
3807
Nick Coghlan14ff9942008-07-08 14:21:42 +00003808- Issue #2517: Allow unicode messages in Exceptions again by correctly

3818 another thread's dictionary.
3819
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003820- Issue #3004: Minor change to slice.indices(): the start and stop
3821 arguments are now treated identically, making the behaviour easier
3822 to describe and understand. For example, slice(None, -10,
3823 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3824 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3825 10, -1).
3826
Georg Brandl278fc502008-07-19 12:46:12 +00003827- Issue #3219: Calling a function with repeated keyword arguments,
3828 f(a=2, a=23), would not cause a syntax error. This was a regression
3829 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003830
Georg Brandl278fc502008-07-19 12:46:12 +00003831- Issue #2862: Make int and float freelist management consistent with
3832 other freelists. Changes their CompactFreeList apis into

3839 api functions without holding the GIL, which could lead to a fatal
3840 error when they failed.
3841
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003842- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003867- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3868 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003869 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003870 content-length. The problem had been corrected in the 2.4 branch, but never
3871 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003886- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4259 an extension. This was added for compatibility with Apple's build
4260 of Python.
4261
4262- The bundled OSX-specific copy of libbffi is now in sync with the version
4263 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
4264
Georg Brandl25c34082008-08-18 23:09:49 +00004265- The threading module gained aliases for names that will be removed in the
4266 3.x series.

4274
Brett Cannonb61d8012008-05-11 23:39:04 +00004275- ``Lib/lib-old`` is now added to sys.path.
4276
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004277- On MacOS X it is now possible to install the framework in 64-bit
4278 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004279 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004280
4281 This is controlled by the configure argument ``--with-universal-archs``:
4282
4283 - ``--with-universal-archs=all``: install 4-way universal
4284
4285 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4286
4287 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4288
4289 This option should be used in combination with ``--enable-universalsdk=``.
4290
4291 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00004300
4301- The PyString functions have been renamed to PyBytes. A batch of
4302 defines were added so that the linker still sees the original
4303 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004341- Issue #1631171: Re-implement the 'warnings' module in C (the
4342 original Python code has been kept as backup). This will allow for
4343 using the 'warning's machinery in such places as the parser where
4344 use of pure Python code is not possible. Both the ``showarning()``
4345 and ``formatwarning()`` gain an optional 'line' argument which is
4346 not called by default for backwards-compatibility reasons. Setting
4347 ``warnings.showwarning()`` to an implementation that lacks support
4348 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004373- The getpass module has been improved on Unix. It now uses /dev/tty
4374 by default and uses stderr instead of stdout. A GetPassWarning is
4375 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004390- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004391 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004411- Issue #2550: The approach used by client/server code for obtaining
4412 ports to listen on in network-oriented tests has been refined in an
4413 effort to facilitate running multiple instances of the entire
4414 regression test suite in parallel without issue.
4415 test_support.bind_port() has been fixed such that it will always
4416 return a unique port -- which wasn't always the case with the
4417 previous implementation, especially if socket options had been set
4418 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4419 new implementation of bind_port() will actually raise an exception
4420 if it is passed an AF_INET/SOCK_STREAM socket with either the
4421 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4422 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4423 the socket it's been passed. This currently only applies to
4424 Windows. This option prevents any other sockets from binding to the
4425 host/port we've bound to, thus removing the possibility of the
4426 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4427 when a second SOCK_STREAM socket binds and accepts to a host/port
4428 that's already been bound by another socket. The optional preferred
4429 port parameter to bind_port() has been removed. Under no
4430 circumstances should tests be hard coding ports!
4431
4432 test_support.find_unused_port() has also been introduced, which will
4433 pass a temporary socket object to bind_port() in order to obtain an
4434 unused port. The temporary socket object is then closed and
4435 deleted, and the port is returned. This method should only be used
4436 for obtaining an unused port in order to pass to an external program
4437 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4438 a parameter to a server-oriented class that doesn't give you direct
4439 access to the underlying socket used.
4440
4441 Finally, test_support.HOST has been introduced, which should be used
4442 for the host argument of any relevant socket calls (i.e. bind and
4443 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004444
4445 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004446 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004447 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4448 test_asynchat and test_socket_ssl.
4449
Georg Brandl3ee81df2008-05-17 18:14:43 +00004450 It is now possible for multiple instances of the regression test
4451 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004730- Added the future_builtins module, which contains hex() and oct().
4731 These are the PEP 3127 version of these functions, designed to be
4732 compatible with the hex() and oct() builtins from Python 3.0. They
4733 differ slightly in their output formats from the existing, unchanged
4734 Python 2.6 builtins. The expected usage of the future_builtins
4735 module is:
4736 from future_builtins import hex, oct
4737
Eric Smith7ef40bf2008-02-20 23:34:22 +00004738- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4739 exponents for exponents with absolute value < 100. Follows C99
4740 standard. This is a change on Windows, which would use 3 digits.
4741 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4742 so that any alterations it does to the resulting string will be
4743 available in stringlib/formatter.h (for float.__format__).
4744
Eric Smith5a3c1352008-02-19 13:21:56 +00004745- Implemented PEP 3101, Advanced String Formatting. This adds a new
4746 builtin format(); a format() method for str and unicode; a
4747 __format__() method to object, str, unicode, int, long, float, and
4748 datetime; the class string.Formatter; and the C API
4749 PyObject_Format().
4750
Georg Brandl3ee81df2008-05-17 18:14:43 +00004751- Fixed several potential crashes, all caused by specially crafted
4752 __del__ methods exploiting objects in temporarily inconsistent
4753 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00004755- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004756 prevent a possible crash: an Abstract Base Class would try to access
4757 a slot on a registered virtual subclass.

4764 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004765
Georg Brandl3ee81df2008-05-17 18:14:43 +00004766- Issue #2045: Fix an infinite recursion triggered when printing a
4767 subclass of collections.defaultdict, if its default_factory is set
4768 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004769
Christian Heimesf75dbef2008-02-08 00:11:31 +00004770- Fixed a minor memory leak in dictobject.c. The content of the free
4771 list was not freed on interpreter shutdown.
4772
Georg Brandl21e99f42010-03-07 15:23:59 +00004773- Limit free list of method and built-in function objects to 256

4777 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004778 to compact the internal free lists of pre-allocted ints and floats.
4779
Georg Brandl3ee81df2008-05-17 18:14:43 +00004780- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4781 calls. Python expected the return type int but the fork familie
4782 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004783
Georg Brandl3ee81df2008-05-17 18:14:43 +00004784- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4785 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004786
Georg Brandl3ee81df2008-05-17 18:14:43 +00004787- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4788 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004789
Georg Brandl3ee81df2008-05-17 18:14:43 +00004790- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4791 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004793- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4794 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004795
Georg Brandl3ee81df2008-05-17 18:14:43 +00004796- Patch #1473257: generator objects gain a gi_code attribute. This is
4797 the same object as the func_code attribute of the function that
4798 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004799
Georg Brandl3ee81df2008-05-17 18:14:43 +00004800- Issue #1920: "while 0" statements were completely removed by the
4801 compiler, even in the presence of an "else" clause, which is
4802 supposed to be run when the condition is false. Now the compiler
4803 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004804
Guido van Rossumeead05f2008-01-24 18:21:02 +00004805- A few crashers fixed: weakref_in_del.py (issue #1377858);
4806 loosing_dict_ref.py (issue #1303614, test67.py);
4807 borrowed_ref_[34].py (not in tracker).
4808
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004809- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004810 suppressed while an extension is loaded by calling SetErrorMode in
4811 dynload_win.c. The error is still reported properly.
4812
Georg Brandl3ee81df2008-05-17 18:14:43 +00004813- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004814 several extension methods and modules do not work without unicode
4815 support.
4816
Georg Brandl26543b12008-01-21 18:36:51 +00004817- Issue #1882: when compiling code from a string, encoding cookies in the
4818 second line of code were not always recognized correctly.
4819
Georg Brandl14404b62008-01-19 19:27:05 +00004820- Issue #1679: "0x" was taken as a valid integer literal.
4821
Georg Brandl6caad7d2008-01-26 14:19:22 +00004822- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004823 added.
4824
Christian Heimesc94e2b52008-01-14 04:13:37 +00004825- sys.float_info / PyFloat_GetInfo: The floating point information
4826 object was converted from a dict to a specialized structseq object.
4827
Georg Brandl3ee81df2008-05-17 18:14:43 +00004828- Patch #1816: Added sys.flags structseq. It exposes the status of
4829 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004830
Georg Brandl3ee81df2008-05-17 18:14:43 +00004831- Objects/structseq.c: Implemented new structseq representation. The
4832 patch makes structseqs (e.g. the return value of os.stat) more
4833 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004834
Georg Brandl3ee81df2008-05-17 18:14:43 +00004835- Patch #1700288: added a type attribute cache that caches method
4836 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004837
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004838- Bug #1776: __import__() no longer accepts filenames on any platform.
4839 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004840
Georg Brandlaed6c662008-01-07 17:25:53 +00004841- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4842
Georg Brandl3ee81df2008-05-17 18:14:43 +00004843- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4844 envvar and sys.dont_write_bytecode attribute. All these can be set
4845 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004846
Georg Brandl3ee81df2008-05-17 18:14:43 +00004847- Improve some exception messages when Windows fails to load an
4848 extension module. Now we get for example '%1 is not a valid Win32
4849 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004850

Georg Brandl3ee81df2008-05-17 18:14:43 +00004853- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4854 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004855
Christian Heimes0a8143f2007-12-18 23:22:54 +00004856- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004857 and INF. float("nan"), float("inf") and float("-inf") now work on
4858 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004859
Georg Brandl3ee81df2008-05-17 18:14:43 +00004860- Compiler now generates simpler and faster code for dictionary
4861 literals. The oparg for BUILD_MAP now indicates an estimated
4862 dictionary size. There is a new opcode, STORE_MAP, for adding
4863 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004892- Patch #1739468: Directories and zipfiles containing a __main__.py
4893 file can now be directly executed by passing their name to the
4894 interpreter. The directory/zipfile is automatically inserted as the
4895 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004896
Georg Brandl3ee81df2008-05-17 18:14:43 +00004897- Issue #1265: Fix a problem with sys.settrace, if the tracing
4898 function uses a generator expression when at the same time the
4899 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004900
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004901- sets and frozensets now have an isdisjoint() method.
4902
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004903- optimize the performance of builtin.sum().
4904
Neal Norwitz44f326e2007-10-05 05:29:17 +00004905- Fix warnings found by the new version of the Coverity checker.
4906
Georg Brandl21e99f42010-03-07 15:23:59 +00004907- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004908 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4909 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004910
Georg Brandl3ee81df2008-05-17 18:14:43 +00004911- Issue #1686386: Tuple's tp_repr did not take into account the
4912 possibility of having a self-referential tuple, which is possible
4913 from C code. Nor did object's tp_str consider that a type's tp_str
4914 could do something that could lead to an inifinite recursion.
4915 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4916 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004917
Georg Brandl3ee81df2008-05-17 18:14:43 +00004918- Issue #1164: It was possible to trigger deadlock when using the
4919 'print' statement to write to a file since the GIL was not released
4920 as needed. Now PyObject_Print() does the right thing along with
4921 various tp_print implementations of the built-in types and those in
4922 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004923
Georg Brandl3ee81df2008-05-17 18:14:43 +00004924- Issue #1147: Exceptions were directly allowing string exceptions in
4925 their throw() method even though string exceptions no longer
4926 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004927
Georg Brandl3ee81df2008-05-17 18:14:43 +00004928- Issue #1096: Prevent a segfault from getting the repr of a very
4929 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004930
Brett Cannon1e534b52007-09-07 04:18:30 +00004931- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004932 PyObject_Call() never calling back out to Python code to trigger
4933 recursion depth updates/checks. Required the creation of a static
4934 RuntimeError instance in case normalizing an exception put the
4935 recursion check value past its limit. Fixes crashers
4936 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004937
Georg Brandl3ee81df2008-05-17 18:14:43 +00004938- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004951- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004952 __*__ attributes. (Some already existed, e.g., __doc__ and
4953 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004954
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004955- Add -3 option to the interpreter to warn about features that are
4956 deprecated and will be changed/removed in Python 3.0.
4957
Georg Brandl2134e752007-05-21 20:34:16 +00004958- Patch #1686487: you can now pass any mapping after '**' in function
4959 calls.
4960
Collin Winter62903052007-05-18 23:11:24 +00004961- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004962 "except E as target:". This is to provide forwards compatibility
4963 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00004965- Deprecate BaseException.message as per PEP 352.
4966
Georg Brandl3ee81df2008-05-17 18:14:43 +00004967- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004968 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004969
Vinay Sajip8549ce32007-05-06 17:53:37 +00004970- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004971 setting a plain string, ie don't expand to single letter identifiers.
4972
Raymond Hettinger13936692007-04-11 18:40:58 +00004973- Request #1191699: Slices can now be pickled.
4974
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004975- Request #1193128: str.translate() now allows a None argument for
4976 translations that only remove characters without re-mapping the
4977 remaining characters.
4978
Georg Brandl5cb76c12007-03-21 09:00:39 +00004979- Patch #1682205: a TypeError while unpacking an iterable is no longer
4980 masked by a generic one with the message "unpack non-sequence".
4981
Neal Norwitzaa754b72007-03-21 06:39:48 +00004982- Remove unused file Python/fmod.c.
4983
Guido van Rossum143b5642007-03-23 04:58:42 +00004984- Bug #1683368: The object.__init__() and object.__new__() methods are
4985 now stricter in rejecting excess arguments. The only time when
4986 either allows excess arguments is when it is not overridden and the
4987 other one is. For backwards compatibility, when both are
4988 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004989 warning later). Also, type.__init__() insists on the same signature
4990 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004992- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4993 object to complex using its __complex__() method before falling back
4994 to the __float__() method. Therefore, the functions in the cmath
4995 module now can operate on objects that define a __complex__()
4996 method.

Georg Brandl871f1bc2007-03-12 13:17:36 +00005017- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005018 its argument, if it exists. If not, it will work like before. This
5019 allows customizing the output of dir() in the presence of a
5020 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00005032- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl3ee81df2008-05-17 18:14:43 +00005544 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005585 AttributeError instead of an IOError when the server's response

5677 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00006070 time so that opening a database previously created with the DB_DUP
6071 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6072 opens. Specifically: dictionary assignment to a DB object will
6073 replace all values for a given key when the database allows
6074 duplicate values. DB users should use DB.put(k, v) when they want
6075 to store duplicates; not DB[k] = v.

6084 behavior of quoting dots if they are the second character of any
6085 line.
