411 of the number of bytes specified by the start byte.
412 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
413 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

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

847
Georg Brandlfee0f442010-05-22 21:26:21 +0000848- Issue #8257: The Decimal construct now accepts a float instance directly,
849 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000850
851 >>> Decimal(1.1)
852 Decimal('1.100000000000000088817841970012523233890533447265625')
853

867 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
868 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +0000870- Issue #2531: Comparison operations between floats and Decimal instances now
871 return a result based on the numeric values of the operands; previously they
872 returned an arbitrary result based on the relative ordering of id(float) and
873 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000875- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000876 argument `-` which tells it to read files to compile from stdin. Each line is
877 read on demand and the named file is compiled immediately. (Original patch by
878 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000887- Comparisons using one of <, <=, >, >= between a complex instance and a
888 Fractions instance now raise TypeError instead of returning True/False. This
889 makes Fraction <=> complex comparisons consistent with int <=> complex, float
890 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +0000994- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
995 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +0000997 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
998 inconsistent: __int__ was used for some integer codes but not for others, and
999 the set of integer codes for which it was used differed between native packing
1000 and standard packing.)

1305 position to the given argument, which goes against the tradition of

1408
Mark Dickinson1b34d252010-01-01 17:27:30 +00001409- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001410 DeprecationWarning when passed a float argument where an integer was expected.
1411 These functions and methods now raise TypeError instead. The majority of the
1412 effects of this change are in the extension modules, but some core functions
1413 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1414 and many unicode/str methods.

1429 least on IEEE 754 platforms), and in particular does not depend on the
1430 internal representation of a long.

1438
Georg Brandlba83f822010-03-14 09:50:54 +00001439 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00001579- Issue #3382: 'F' formatting for float and complex now convert the result to
1580 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1581 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001582
Georg Brandlba83f822010-03-14 09:50:54 +00001583- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1584 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001585
Georg Brandlba83f822010-03-14 09:50:54 +00001586- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1587 1e-100 used to raise OverflowError, but now gives the requested 120
1588 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001596
Georg Brandlba83f822010-03-14 09:50:54 +00001597- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1598 decimal string that's guaranteed to round back to x under correct rounding
1599 (with round-half-to-even rounding mode). Previously it gave a string based on
1600 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1601 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1602 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001603
Georg Brandlba83f822010-03-14 09:50:54 +00001604- Issue #7117: On almost all platforms: float-to-string and string-to-float
1605 conversions within Python are now correctly rounded. Places these conversions
1606 occur include: str for floats and complex numbers; the float and complex
1607 constructors; old-style and new-style numeric formatting; serialization and
1608 deserialization of floats and complex numbers using marshal, pickle and json;
1609 parsing of float and imaginary literals in Python code; Decimal-to-float
1610 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001611
Georg Brandlba83f822010-03-14 09:50:54 +00001612 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1613 providing correctly-rounded strtod and dtoa C functions. This code is
1614 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1615 the C compiler. There may be a small number of platforms on which correct
1616 operation of this code cannot be guaranteed, so the code is not used: notably,
1617 this applies to platforms where the C double format is not IEEE 754 binary64,
1618 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1619 and Python's configure script is unable to determine how to change the FPU
1620 precision. On these platforms conversions use the platform strtod and dtoa,
1621 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001622
Georg Brandlba83f822010-03-14 09:50:54 +00001623- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1624 uses the correctly-rounded string <-> float conversions described above (when
1625 available), and so produces correctly rounded results that will display nicely
1626 under the float repr. There are two related small changes: (1) round now
1627 accepts any class with an ``__index__()`` method for its second argument (but
1628 no longer accepts floats for the second argument), and (2) an excessively
1629 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1630 raises an exception.

1633
Georg Brandlba83f822010-03-14 09:50:54 +00001634- Fix several issues with ``compile()``. The input can now contain Windows and

1857 internal representation of integers, for performance reasons. Base 2**30 is
1858 enabled by default on 64-bit machines. Add --enable-big-digits option to
1859 configure, which overrides the default. Add sys.long_info structseq to

Georg Brandl29c6a282009-04-05 20:23:13 +00001892- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00001893 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00001923- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1924 existing .py counterpart, override the co_filename attributes of all code
1925 objects if the original filename is obsolete (which can happen if the file has

3410
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003411- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3412
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003413- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3414 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3415 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3416 ``printf`` function, whereas PyString_FromFormat has an independent
3417 implementation and uses "%zd" on all platforms for size_t values.
3418 This makes a difference on win64, where ``printf`` needs "%Id" to display
3419 64bit values.
3420
Benjamin Peterson97179b02008-09-09 20:55:01 +00003421- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3422 error.
3423
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003424- Issue #3777: long() applied to a float object now always return a long
3425 object; previously an int would be returned for small values. the __long__
3426 method is allowed to return either an int or a long, but the behaviour of
3427 float objects should not change to respect backward compatibility.
3428
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003429- Issue #3751: str.rpartition would perform a left-partition when called with
3430 a unicode argument.
3431
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003432- Issue #3683: Fix compilation when --without-threads is given.
3433
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003434- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003435 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003436 was correctly parsed but parsing of subsequent arguments failed.
3437
Vinay Sajip35e3b032008-09-01 14:33:59 +00003438- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003439 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3440 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3441 when given a tuple of classes as second argument, were looking up
3442 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3443 type object.
3444
Neal Norwitz18aa3882008-08-24 05:04:52 +00003445- Fix crashes on memory allocation failure found with failmalloc.
3446
3447- Fix memory leaks found with valgrind and update suppressions file.
3448
3449- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3450
3451- Fix problem using wrong name in decimal module reported by pychecker.
3452
Christian Heimes7d4c3172008-08-22 19:47:25 +00003453- Silenced another compiler warning about a used but not defined
3454 function 'stringlib_contains_obj'.
3455
Benjamin Peterson712ee922008-08-24 18:10:20 +00003456- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
3457 ``__delslice__``.
3458
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003459- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3460 library targets in the Makefile.
3461
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003462- Issue #1204: The configure script now tests for additional libraries
3463 that may be required when linking against readline. This fixes issues
3464 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
3465
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00003466C-API

3473
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00003474- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
3475 stack usage in the case of deeply nested objects.
3476
Guido van Rossume3c4fd92008-09-10 14:27:00 +00003477- Issue #3629: Fix sre "bytecode" validator for an end case.
3478
Martin v. Löwis24329ba2008-09-10 13:38:12 +00003479- Issue #3811: The Unicode database was updated to 5.1.
3480
Nick Coghland2e09382008-09-11 12:11:06 +00003481- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
3482 silent misbehaviour when a single instance is nested in multiple
3483 with statements, or when the methods are invoked in the wrong order.
3484
Vinay Sajip844f7412008-09-09 13:42:08 +00003485- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
3486
Nick Coghland2e09382008-09-11 12:11:06 +00003487- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003488 return a list or None rather than a custom object.
3489
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003490- Issue #1638033: Cookie.Morsel gained the httponly attribute.
3491
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00003492- Issue #3535: zipfile couldn't read some zip files larger than 2GB.
3493
3494- Issue #3776: Deprecate the bsddb package for removal in 3.0.
Brett Cannon32476fc2008-09-05 18:33:51 +00003495
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +00003496- Issue #3762: platform.architecture() fails if python is lanched via
3497 its symbolic link.
3498
Vinay Sajip65d66e12008-09-04 07:31:21 +00003499- Issue #3772: Fixed regression problem in StreamHandler.emit().

Facundo Batistac585df92008-09-03 22:35:50 +00003502 to the urlparse one. Added a PendingDeprecationWarning in the old
3503 module, it will be deprecated in the future.
3504
Marc-André Lemburgb339b2a2008-09-03 11:13:56 +00003505- Issue #2562: Fix distutils PKG-INFO writing logic to allow having

3511 path to the Python binary.
3512
Georg Brandl222e2082010-08-01 22:27:39 +00003513- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00003514 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3515 for catch_warnings() also led to an improvement in the raising of a
3516 DeprecationWarning related to warnings.warn_explicit().
3517
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003518- The deprecation warnings for the old camelCase threading API were removed.
3519
Vinay Sajip35e3b032008-09-01 14:33:59 +00003520- logging: fixed lack of use of encoding attribute specified on a stream.
3521
Christian Heimesa27a62e2008-08-22 19:55:54 +00003522- Silenced a trivial compiler warning in the sqlite module.
3523
Christian Heimes1cc69632008-08-22 20:10:27 +00003524- Fixed two format strings in the _collections module.
3525
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003526- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a
3527 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00003528
Gregory P. Smithd7122032008-09-02 05:36:11 +00003529- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
3530 non-integer floating point number.
3531
Vinay Sajip65d66e12008-09-04 07:31:21 +00003532- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

3537
Jesse Noller438195f2009-01-18 21:04:36 +00003538- Issue #4301: Patch the logging module to add processName support, remove
3539 _check_logger_class from multiprocessing.
3540
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003541- Issue #2975: When compiling several extension modules with Visual Studio 2008
3542 from the same python interpreter, some environment variables would grow
3543 without limit.
3544
Benjamin Peterson37346b22008-08-23 20:27:43 +00003545- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3546 exploitation of poor argument checking.
3547
Gerhard Häringef2276b2008-09-12 13:54:06 +00003548- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
3549
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00003550- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
3551 remaining ones have "pysqlite_" prefix.
3552
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003553- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

3559
Nick Coghland2e09382008-09-11 12:11:06 +00003560- Issue #3781: Add test.test_support.check_warnings() as a convenience
3561 wrapper for warnings.catch_warnings() that makes it easier to check
3562 that expected warning messages are being reported.
3563
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003564- Issue #3796: Some tests functions were not enabled in test_float.
3565
3566- Issue #3768: Move test_py3kwarn over to the new API for catch_warnings().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003582What's New in Python 2.6 beta 3?
3583================================
3584
Barry Warsaw07a4a382008-08-21 01:15:08 +00003585*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003586
3587Core and Builtins
3588-----------------
3589
Guido van Rossumf8402962008-08-20 15:01:50 +00003590- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3591 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3592 extensions do not automatically benefit from the class attribute
3593 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3594 to their tp_flags field if they care. This is a backwards
3595 compatibility feature; in 3.0, all types will use the cache by
3596 default.
3597
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003598- Keyword arguments can now follow starred arguments. (``f(a, *args,
3599 keyword=23)`` is now valid syntax.)
3600
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003601- ctypes function pointers that are COM methods have a boolean True
3602 value again.
3603
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003604- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3605 by denying s# to parse objects that have a releasebuffer procedure,
3606 and introducing s*.
3607
Georg Brandl1e13ea92008-08-11 09:07:59 +00003608- Issue #3537: Fix an assertion failure when an empty but presized dict
3609 object was stored in the freelist.
3610
Mark Dickinsonb6467572008-08-04 21:30:09 +00003611- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3612 ValueError consistently across platforms.
3613
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003614- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3615 (64bit Unix, for example), unichr() would truncate its argument and return
3616 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3617
Neal Norwitze7d8be82008-07-31 17:17:14 +00003618- Apply security patches from Apple.
3619
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003620- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3621 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3622
Antoine Pitrou92f82162008-07-25 22:22:08 +00003623- Issue #1819: function calls with several named parameters are now on
3624 average 35% faster (as measured by pybench).
3625
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003626- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3627 the python debugger steps into a class statement: the free variables (local
3628 variables defined in an outer scope) would be deleted from the outer scope.
3629
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003630- Issue #2620: Overflow checking when allocating or reallocating memory
3631 was not always being done properly in some python types and extension
3632 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3633 all been updated to perform better checks and places in the code that
3634 would previously leak memory on the error path when such an allocation
3635 failed have been fixed.

3638-------
3639
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003640- Issue #3612: Added some missing basic types in ctypes.wintypes.
3641
Benjamin Petersone977ad42008-08-20 01:42:01 +00003642- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3643 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3644
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003645- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3646 version reported by these tools does not necessarily follow the python
3647 version numbering scheme, so the module is less strict when parsing it.
3648
Nick Coghlanf70385a2008-08-18 12:42:46 +00003649- Issue #2235: Added Py3k warnings for types which will become unhashable
3650 under the stricter __hash__ inheritance rules in 3.0. Several types
3651 which did not meet the rules for hash invariants and were already
3652 unhashable in 3.0 have now been explicitly flagged as unhashable in
3653 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3654 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3655
Brett Cannon88f801d2008-08-18 00:46:22 +00003656- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3657 imported into the module but exposed as part of the module's API.
3658
Brett Cannon7b96f072008-08-18 00:41:11 +00003659- Remove an unneeded import of abc.ABCMeta from 'inspect'.

3664
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003665- Issue #3575: Incremental decoder's decode function now takes bytearray
3666 by using 's*' instead of 't#'.
3667
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003668- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003669 fails unicode conversion on 2nd parameter. (windows only)
3670
Georg Brandl222e2082010-08-01 22:27:39 +00003671- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003672 in a redirect.
3673
Brett Cannonabe423e2008-08-16 21:47:07 +00003674- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003675 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003676
Facundo Batistaeb90b782008-08-16 14:44:07 +00003677- Issue #2776: fixed small issue when handling an URL with double slash
3678 after a 302 response in the case of not going through a proxy.
3679
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003680- Issue #2676: in the email package, content-type parsing was hanging on
3681 pathological input because of quadratic or exponential behaviour of a
3682 regular expression.
3683
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003684- Issue #3476: binary buffered reading through the new "io" library is now
3685 thread-safe.
3686
Brett Cannonbf3157b2008-08-14 05:00:03 +00003687- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3688 since mimetools itself is deprecated. Because modules are cached, all
3689 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3690
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003691- Issue #3134: shutil referenced undefined WindowsError symbol.
3692
Robert Schuppenies14646332008-08-10 11:01:53 +00003693- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3694 menu entries were not deleted.

Antoine Pitroude781a42008-08-09 12:43:23 +00003725 asking for a specific length. This problem only affected files opened

3769
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003770- Issue #643841: The language reference now provides more detailed

3782-----------------
3783
Georg Brandl3e483f62008-07-16 22:57:41 +00003784- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3785 its methods now allow for items objects that can be converted to
3786 an integer using operator.index().
3787
Mark Dickinson64b7e502008-07-16 09:40:03 +00003788- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3789 produced a ValueError instead of giving the correct float.
3790
Eric Smitha5fa5a22008-07-16 00:11:49 +00003791- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3792 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3793
Mark Dickinson7103aa42008-07-15 19:08:33 +00003794- Issue #3008: the float type has a new instance method 'float.hex'
3795 and a new class method 'float.fromhex' to convert floating-point
3796 numbers to and from hexadecimal strings, respectively.
3797
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003798- Issue #2235: __hash__ is once again inherited by default. To allow
3799 collections.Hashable to remain meaningful in the presence of the
3800 default hash implementation (object.__hash__), it is now possible
3801 to explicit block inheritance of hash by setting __hash__=None at
3802 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3803 level.
3804
Nick Coghlanb028f502008-07-13 14:52:36 +00003805- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3806 the parent module cannot be found while performing an absolute import.
3807 This means that an incorrectly defined __package__ attribute will
3808 now only prevent relative imports in that module rather than causing
3809 all imports from that module to fail.
3810
Nick Coghlan14ff9942008-07-08 14:21:42 +00003811- Issue #2517: Allow unicode messages in Exceptions again by correctly

3821 another thread's dictionary.
3822
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003823- Issue #3004: Minor change to slice.indices(): the start and stop
3824 arguments are now treated identically, making the behaviour easier
3825 to describe and understand. For example, slice(None, -10,
3826 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3827 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3828 10, -1).
3829
Georg Brandl278fc502008-07-19 12:46:12 +00003830- Issue #3219: Calling a function with repeated keyword arguments,
3831 f(a=2, a=23), would not cause a syntax error. This was a regression
3832 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003833
Georg Brandl278fc502008-07-19 12:46:12 +00003834- Issue #2862: Make int and float freelist management consistent with
3835 other freelists. Changes their CompactFreeList apis into

3842 api functions without holding the GIL, which could lead to a fatal
3843 error when they failed.
3844
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003845- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003870- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3871 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003872 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003873 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003889- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4262 an extension. This was added for compatibility with Apple's build
4263 of Python.
4264
4265- The bundled OSX-specific copy of libbffi is now in sync with the version
4266 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
4267
Georg Brandl25c34082008-08-18 23:09:49 +00004268- The threading module gained aliases for names that will be removed in the
4269 3.x series.

4277
Brett Cannonb61d8012008-05-11 23:39:04 +00004278- ``Lib/lib-old`` is now added to sys.path.
4279
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004280- On MacOS X it is now possible to install the framework in 64-bit
4281 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004282 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004283
4284 This is controlled by the configure argument ``--with-universal-archs``:
4285
4286 - ``--with-universal-archs=all``: install 4-way universal
4287
4288 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4289
4290 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4291
4292 This option should be used in combination with ``--enable-universalsdk=``.
4293
4294 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 +00004303
4304- The PyString functions have been renamed to PyBytes. A batch of
4305 defines were added so that the linker still sees the original
4306 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004344- Issue #1631171: Re-implement the 'warnings' module in C (the
4345 original Python code has been kept as backup). This will allow for
4346 using the 'warning's machinery in such places as the parser where
4347 use of pure Python code is not possible. Both the ``showarning()``
4348 and ``formatwarning()`` gain an optional 'line' argument which is
4349 not called by default for backwards-compatibility reasons. Setting
4350 ``warnings.showwarning()`` to an implementation that lacks support
4351 for the ``line`` argument will raise a DeprecationWarning.

4375
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004376- The getpass module has been improved on Unix. It now uses /dev/tty
4377 by default and uses stderr instead of stdout. A GetPassWarning is
4378 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004393- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004394 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004414- Issue #2550: The approach used by client/server code for obtaining
4415 ports to listen on in network-oriented tests has been refined in an
4416 effort to facilitate running multiple instances of the entire
4417 regression test suite in parallel without issue.
4418 test_support.bind_port() has been fixed such that it will always
4419 return a unique port -- which wasn't always the case with the
4420 previous implementation, especially if socket options had been set
4421 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4422 new implementation of bind_port() will actually raise an exception
4423 if it is passed an AF_INET/SOCK_STREAM socket with either the
4424 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4425 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4426 the socket it's been passed. This currently only applies to
4427 Windows. This option prevents any other sockets from binding to the
4428 host/port we've bound to, thus removing the possibility of the
4429 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4430 when a second SOCK_STREAM socket binds and accepts to a host/port
4431 that's already been bound by another socket. The optional preferred
4432 port parameter to bind_port() has been removed. Under no
4433 circumstances should tests be hard coding ports!
4434
4435 test_support.find_unused_port() has also been introduced, which will
4436 pass a temporary socket object to bind_port() in order to obtain an
4437 unused port. The temporary socket object is then closed and
4438 deleted, and the port is returned. This method should only be used
4439 for obtaining an unused port in order to pass to an external program
4440 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4441 a parameter to a server-oriented class that doesn't give you direct
4442 access to the underlying socket used.
4443
4444 Finally, test_support.HOST has been introduced, which should be used
4445 for the host argument of any relevant socket calls (i.e. bind and
4446 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004447
4448 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004449 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004450 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4451 test_asynchat and test_socket_ssl.
4452
Georg Brandl3ee81df2008-05-17 18:14:43 +00004453 It is now possible for multiple instances of the regression test
4454 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00004723- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004724 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00004733- Added the future_builtins module, which contains hex() and oct().
4734 These are the PEP 3127 version of these functions, designed to be
4735 compatible with the hex() and oct() builtins from Python 3.0. They
4736 differ slightly in their output formats from the existing, unchanged
4737 Python 2.6 builtins. The expected usage of the future_builtins
4738 module is:
4739 from future_builtins import hex, oct
4740
Eric Smith7ef40bf2008-02-20 23:34:22 +00004741- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4742 exponents for exponents with absolute value < 100. Follows C99
4743 standard. This is a change on Windows, which would use 3 digits.
4744 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4745 so that any alterations it does to the resulting string will be
4746 available in stringlib/formatter.h (for float.__format__).
4747
Eric Smith5a3c1352008-02-19 13:21:56 +00004748- Implemented PEP 3101, Advanced String Formatting. This adds a new
4749 builtin format(); a format() method for str and unicode; a
4750 __format__() method to object, str, unicode, int, long, float, and
4751 datetime; the class string.Formatter; and the C API
4752 PyObject_Format().
4753
Georg Brandl3ee81df2008-05-17 18:14:43 +00004754- Fixed several potential crashes, all caused by specially crafted
4755 __del__ methods exploiting objects in temporarily inconsistent
4756 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00004758- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004759 prevent a possible crash: an Abstract Base Class would try to access
4760 a slot on a registered virtual subclass.

4766 in order to allow pymalloc to free more arenas. Python may give back
4767 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004768
Georg Brandl3ee81df2008-05-17 18:14:43 +00004769- Issue #2045: Fix an infinite recursion triggered when printing a
4770 subclass of collections.defaultdict, if its default_factory is set
4771 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004772
Christian Heimesf75dbef2008-02-08 00:11:31 +00004773- Fixed a minor memory leak in dictobject.c. The content of the free
4774 list was not freed on interpreter shutdown.
4775
Georg Brandl21e99f42010-03-07 15:23:59 +00004776- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00004778
Georg Brandl3ee81df2008-05-17 18:14:43 +00004779- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4780 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004781 to compact the internal free lists of pre-allocted ints and floats.
4782
Georg Brandl3ee81df2008-05-17 18:14:43 +00004783- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4784 calls. Python expected the return type int but the fork familie
4785 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004786
Georg Brandl3ee81df2008-05-17 18:14:43 +00004787- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4788 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004789
Georg Brandl3ee81df2008-05-17 18:14:43 +00004790- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4791 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004792
Georg Brandl3ee81df2008-05-17 18:14:43 +00004793- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4794 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004796- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4797 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004798
Georg Brandl3ee81df2008-05-17 18:14:43 +00004799- Patch #1473257: generator objects gain a gi_code attribute. This is
4800 the same object as the func_code attribute of the function that
4801 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004802
Georg Brandl3ee81df2008-05-17 18:14:43 +00004803- Issue #1920: "while 0" statements were completely removed by the
4804 compiler, even in the presence of an "else" clause, which is
4805 supposed to be run when the condition is false. Now the compiler
4806 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004807
Guido van Rossumeead05f2008-01-24 18:21:02 +00004808- A few crashers fixed: weakref_in_del.py (issue #1377858);
4809 loosing_dict_ref.py (issue #1303614, test67.py);
4810 borrowed_ref_[34].py (not in tracker).
4811
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004812- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004813 suppressed while an extension is loaded by calling SetErrorMode in
4814 dynload_win.c. The error is still reported properly.
4815
Georg Brandl3ee81df2008-05-17 18:14:43 +00004816- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004817 several extension methods and modules do not work without unicode
4818 support.
4819
Georg Brandl26543b12008-01-21 18:36:51 +00004820- Issue #1882: when compiling code from a string, encoding cookies in the
4821 second line of code were not always recognized correctly.
4822
Georg Brandl14404b62008-01-19 19:27:05 +00004823- Issue #1679: "0x" was taken as a valid integer literal.
4824
Georg Brandl6caad7d2008-01-26 14:19:22 +00004825- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004826 added.
4827
Christian Heimesc94e2b52008-01-14 04:13:37 +00004828- sys.float_info / PyFloat_GetInfo: The floating point information
4829 object was converted from a dict to a specialized structseq object.
4830
Georg Brandl3ee81df2008-05-17 18:14:43 +00004831- Patch #1816: Added sys.flags structseq. It exposes the status of
4832 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004833
Georg Brandl3ee81df2008-05-17 18:14:43 +00004834- Objects/structseq.c: Implemented new structseq representation. The
4835 patch makes structseqs (e.g. the return value of os.stat) more
4836 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004837
Georg Brandl3ee81df2008-05-17 18:14:43 +00004838- Patch #1700288: added a type attribute cache that caches method
4839 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004840
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004841- Bug #1776: __import__() no longer accepts filenames on any platform.
4842 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004843
Georg Brandlaed6c662008-01-07 17:25:53 +00004844- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4845
Georg Brandl3ee81df2008-05-17 18:14:43 +00004846- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4847 envvar and sys.dont_write_bytecode attribute. All these can be set
4848 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004849
Georg Brandl3ee81df2008-05-17 18:14:43 +00004850- Improve some exception messages when Windows fails to load an
4851 extension module. Now we get for example '%1 is not a valid Win32
4852 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004853
Georg Brandl3ee81df2008-05-17 18:14:43 +00004854- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004856- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4857 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004858
Christian Heimes0a8143f2007-12-18 23:22:54 +00004859- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004860 and INF. float("nan"), float("inf") and float("-inf") now work on
4861 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004862
Georg Brandl3ee81df2008-05-17 18:14:43 +00004863- Compiler now generates simpler and faster code for dictionary
4864 literals. The oparg for BUILD_MAP now indicates an estimated
4865 dictionary size. There is a new opcode, STORE_MAP, for adding
4866 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004895- Patch #1739468: Directories and zipfiles containing a __main__.py
4896 file can now be directly executed by passing their name to the
4897 interpreter. The directory/zipfile is automatically inserted as the
4898 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004899
Georg Brandl3ee81df2008-05-17 18:14:43 +00004900- Issue #1265: Fix a problem with sys.settrace, if the tracing
4901 function uses a generator expression when at the same time the
4902 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004903
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004904- sets and frozensets now have an isdisjoint() method.
4905
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004906- optimize the performance of builtin.sum().
4907
Neal Norwitz44f326e2007-10-05 05:29:17 +00004908- Fix warnings found by the new version of the Coverity checker.
4909
Georg Brandl21e99f42010-03-07 15:23:59 +00004910- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004911 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4912 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004913
Georg Brandl3ee81df2008-05-17 18:14:43 +00004914- Issue #1686386: Tuple's tp_repr did not take into account the
4915 possibility of having a self-referential tuple, which is possible
4916 from C code. Nor did object's tp_str consider that a type's tp_str
4917 could do something that could lead to an inifinite recursion.
4918 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4919 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004920
Georg Brandl3ee81df2008-05-17 18:14:43 +00004921- Issue #1164: It was possible to trigger deadlock when using the
4922 'print' statement to write to a file since the GIL was not released
4923 as needed. Now PyObject_Print() does the right thing along with
4924 various tp_print implementations of the built-in types and those in
4925 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004926
Georg Brandl3ee81df2008-05-17 18:14:43 +00004927- Issue #1147: Exceptions were directly allowing string exceptions in
4928 their throw() method even though string exceptions no longer
4929 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004930
Georg Brandl3ee81df2008-05-17 18:14:43 +00004931- Issue #1096: Prevent a segfault from getting the repr of a very
4932 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004933
Brett Cannon1e534b52007-09-07 04:18:30 +00004934- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004935 PyObject_Call() never calling back out to Python code to trigger
4936 recursion depth updates/checks. Required the creation of a static
4937 RuntimeError instance in case normalizing an exception put the
4938 recursion check value past its limit. Fixes crashers
4939 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004940

Neal Norwitz0ac60192007-05-27 04:08:54 +00004954- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004955 __*__ attributes. (Some already existed, e.g., __doc__ and
4956 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004957
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004958- Add -3 option to the interpreter to warn about features that are
4959 deprecated and will be changed/removed in Python 3.0.
4960
Georg Brandl2134e752007-05-21 20:34:16 +00004961- Patch #1686487: you can now pass any mapping after '**' in function
4962 calls.
4963
Collin Winter62903052007-05-18 23:11:24 +00004964- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004965 "except E as target:". This is to provide forwards compatibility
4966 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00004968- Deprecate BaseException.message as per PEP 352.
4969
Georg Brandl3ee81df2008-05-17 18:14:43 +00004970- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004971 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004972
Vinay Sajip8549ce32007-05-06 17:53:37 +00004973- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004974 setting a plain string, ie don't expand to single letter identifiers.
4975
Raymond Hettinger13936692007-04-11 18:40:58 +00004976- Request #1191699: Slices can now be pickled.
4977
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004978- Request #1193128: str.translate() now allows a None argument for
4979 translations that only remove characters without re-mapping the
4980 remaining characters.
4981
Georg Brandl5cb76c12007-03-21 09:00:39 +00004982- Patch #1682205: a TypeError while unpacking an iterable is no longer
4983 masked by a generic one with the message "unpack non-sequence".
4984
Neal Norwitzaa754b72007-03-21 06:39:48 +00004985- Remove unused file Python/fmod.c.
4986
Guido van Rossum143b5642007-03-23 04:58:42 +00004987- Bug #1683368: The object.__init__() and object.__new__() methods are
4988 now stricter in rejecting excess arguments. The only time when
4989 either allows excess arguments is when it is not overridden and the
4990 other one is. For backwards compatibility, when both are
4991 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004992 warning later). Also, type.__init__() insists on the same signature
4993 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004995- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4996 object to complex using its __complex__() method before falling back
4997 to the __float__() method. Therefore, the functions in the cmath
4998 module now can operate on objects that define a __complex__()
4999 method.

Georg Brandl871f1bc2007-03-12 13:17:36 +00005020- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005021 its argument, if it exists. If not, it will work like before. This
5022 allows customizing the output of dir() in the presence of a
5023 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00005035- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl3ee81df2008-05-17 18:14:43 +00005547 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00006073 time so that opening a database previously created with the DB_DUP
6074 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6075 opens. Specifically: dictionary assignment to a DB object will
6076 replace all values for a given key when the database allows
6077 duplicate values. DB users should use DB.put(k, v) when they want
6078 to store duplicates; not DB[k] = v.

6085 characters with ASCII value less than 32. Also, it correctly quotes
6086 dots only if they occur on a single line, as opposed to the previous
6087 behavior of quoting dots if they are the second character of any
6088 line.
