1096 In particular, fix extension module build failures when trying to use
1097 32-bit-only installer Pythons on systems with Xcode 4 (currently
1098 OS X 10.8, 10.7, and optionally 10.6).
1099 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1100 * Since Xcode 4 removes ppc support, extension module builds now
1101 check for ppc compiler support and by default remove ppc and
1102 ppc64 archs when they are not available.
1103 * Extension module builds now revert to using system installed
1104 headers and libs (/usr and /System/Library) if the SDK used
1105 to build the interpreter is not installed or has moved.
1106 * Try to avoid building extension modules with deprecated
1107 and problematic Apple llvm-gcc compiler. If original compiler
1108 is not available, use clang instead by default.

Ned Deilyc47a4592012-02-11 20:40:24 +01001533 has left two versions of customize_compiler, the original in

Ned Deily0d0ea482012-02-10 12:59:06 +01001539- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1540 Distutils-based packages with C extension modules may fail because
1541 Apple has removed gcc-4.2, the version used to build python.org
1542 64-bit/32-bit Pythons. If the user does not explicitly override
1543 the default C compiler by setting the CC environment variable,
1544 Distutils will now attempt to compile extension modules with clang
1545 if gcc-4.2 is required but not found. Also as a convenience, if
1546 the user does explicitly set CC, substitute its value as the default
1547 compiler in the Distutils LDSHARED configuration variable for OS X.
1548 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1549 SDK, neither of which are available in Xcode 4. This change does not
1550 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001800- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1801 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1802 interpreter process. This could cause failures in non-Distutils subprocesses
1803 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001804 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001805 deployment target only in the environment of each build subprocess. It is
1806 still possible to globally override the default by setting
1807 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1808 greater or equal to the default value, the value with which the interpreter
1809 was built.

1839 the ticker doesn't have to wind down to zero from the old starting point
1840 before the new interval takes effect. And if the user increases the
1841 interval, it makes sure the new limit takes effect right away rather have an
1842 early task switch before recognizing the new interval.

2675 thread-local storage key.
2676
Victor Stinnercaafd772010-09-08 10:51:01 +00002677- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
2678 encoding and errors attributes instead of using utf-8 in strict mode, to get
2679 the same behaviour than the print statement.
2680
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00002681- Issue #9737: Fix a crash when trying to delete a slice or an item from

2695
2696 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2697 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

2809 SSLSocket.sendto() to match the corresponding socket methods. Also,
2810 fix various SSLSocket methods to raise socket.error rather than an
2811 unhelpful TypeError when called on an unconnected socket. Original patch
2812 by Andrew Bennetts.
2813
Raymond Hettinger74f869e2010-09-13 22:14:36 +00002814- Issue #9826: OrderedDict.__repr__ can now handle self-referential
2815 values: d['x'] = d.
2816
Victor Stinner8fc843b2010-09-17 23:35:50 +00002817- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

Antoine Pitroue4195e82010-09-12 14:56:27 +00002819- Issue #9837: The read() method of ZipExtFile objects (as returned by

2821
Raymond Hettinger20397532010-09-12 02:11:45 +00002822- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2823 This prevents user-created self-referencing ordered dictionaries from
2824 becoming permanently uncollectable GC garbage. The downside is that
2825 removing __del__ means that the internal doubly-linked list has to wait for
2826 GC collection rather than freeing memory immediately when the refcnt drops
2827 to zero.
2828
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002829- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

2832
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002833- Issue #9792: In case of connection failure, socket.create_connection()
2834 would swallow the exception and raise a new one, making it impossible
2835 to fetch the original errno, or to filter timeout errors. Now the
2836 original error is re-raised.
2837
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002838- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2839 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2840 be updated back after the system call. Original patch by Brian Brazil.
2841
Antoine Pitroudca9de92010-09-04 17:52:26 +00002842- Issue #1100562: Fix deep-copying of objects derived from the list and

2847
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002848- Issue #808164: Fixed socket.close to avoid references to globals, to
2849 avoid issues when socket.close is called from a __del__ method.
2850
Terry Reedyd2d2ae92010-11-11 23:22:19 +00002851- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

2853 heuristic. Patch by Terry Reedy and Eli Bendersky

2856 falling into recursion.
2857
R. David Murray7c4bf552010-08-25 01:45:57 +00002858- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2859 character years even if the message contains RFC822 two character years.
2860
Daniel Stutzbach91287322010-08-24 21:09:30 +00002861- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00002872- Issue #9214: Set operations on KeysView or ItemsView in the collections
2873 module now correctly return a set. (Patch by Eli Bendersky.)
2874
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002875- Issue #9617: Signals received during a low-level write operation aren't
2876 ignored by the buffered IO layer anymore.
2877
Benjamin Peterson52c36052010-08-21 03:03:22 +00002878- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2879 are not held onto after they are deleted elsewhere.
2880
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002881- Issue #9626: the view methods for collections.OrderedDict() were returning

2883 overridden to provide ordered views.
2884
Éric Araujo0389ae62010-08-14 03:07:46 +00002885- Issue #8688: MANIFEST files created by distutils now include a magic
2886 comment indicating they are generated. Manually maintained MANIFESTs
2887 without this marker will not be overwritten or removed.
2888
Antoine Pitroue1436d12010-08-12 15:25:51 +00002889- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2890 and a BadZipfile error is raised if it doesn't match (as used to be the
2891 case in Python 2.5 and earlier).
2892
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002893- Issue #9550: a BufferedReader could issue an additional read when the
2894 original read request had been satisfied, which could block indefinitely
2895 when the underlying raw IO channel was e.g. a socket. Report and original
2896 patch by Jason V. Miller.
2897
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002898- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00002916- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2917 This is how it is supposed to work, wget and curl do the same. Previous
2918 behavior was wrong.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003286- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3287 start byte and the continuation byte(s) are now considered invalid, instead
3288 of the number of bytes specified by the start byte.
3289 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3290 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3291 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3292 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003300- Issue #8748: Fix two issues with comparisons between complex and integer
3301 objects. (1) The comparison could incorrectly return True in some cases
3302 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3303 (2) The comparison raised an OverflowError for large integers, leading
3304 to unpredictable exceptions when combining integers and complex objects
3305 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003307- Issue #5211: Implicit coercion for the complex type is now completely

3688 with a non-empty format string. This is an effort to future-proof user
3689 code. If a derived class does not currently implement __format__ but later
3690 adds its own __format__, it would most likely break user code that had

3724
Georg Brandlfee0f442010-05-22 21:26:21 +00003725- Issue #8257: The Decimal construct now accepts a float instance directly,
3726 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003727
3728 >>> Decimal(1.1)
3729 Decimal('1.100000000000000088817841970012523233890533447265625')
3730

Georg Brandlfee0f442010-05-22 21:26:21 +00003742- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3743 InvalidOperation instead of returning False. (Comparisons involving a quiet
3744 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3745 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003746
Georg Brandlfee0f442010-05-22 21:26:21 +00003747- Issue #2531: Comparison operations between floats and Decimal instances now
3748 return a result based on the numeric values of the operands; previously they
3749 returned an arbitrary result based on the relative ordering of id(float) and
3750 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003751
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003752- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003753 argument `-` which tells it to read files to compile from stdin. Each line is
3754 read on demand and the named file is compiled immediately. (Original patch by
3755 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003756
Georg Brandlfee0f442010-05-22 21:26:21 +00003757- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Georg Brandlfee0f442010-05-22 21:26:21 +00003764- Comparisons using one of <, <=, >, >= between a complex instance and a
3765 Fractions instance now raise TypeError instead of returning True/False. This
3766 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3767 <=> complex, and complex <=> complex comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003823 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3824 log file to compute the next rollover time. If the log file does not exist,

Georg Brandlba83f822010-03-14 09:50:54 +00003835- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3836 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3837 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003866- Issue #8300: When passing a non-integer argument to struct.pack with any
3867 integer format code, struct.pack first attempts to convert the non-integer
3868 using its __index__ method. If that method is non-existent or raises
3869 TypeError it goes on to try the __int__ method, as described below.
3870
Georg Brandlba83f822010-03-14 09:50:54 +00003871- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3872 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3873 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003874 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3875 inconsistent: __int__ was used for some integer codes but not for others, and
3876 the set of integer codes for which it was used differed between native packing
3877 and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004184- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004185 file position when calling `truncate()`. It would previously change the file
4186 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004187 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00004189- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4190 class used to represent files stored inside an archive. The new
4191 implementation is significantly faster and can be wrapped in a
4192 ``io.BufferedReader`` object for more speedups. It also solves an issue
4193 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004284- The ``__complex__()`` method is now looked up on the class of instances to
4285 make it consistent with other special methods.

4289
Mark Dickinson1b34d252010-01-01 17:27:30 +00004290- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004291 DeprecationWarning when passed a float argument where an integer was expected.
4292 These functions and methods now raise TypeError instead. The majority of the
4293 effects of this change are in the extension modules, but some core functions
4294 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4295 and many unicode/str methods.

4310 least on IEEE 754 platforms), and in particular does not depend on the
4311 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004460- Issue #3382: 'F' formatting for float and complex now convert the result to
4461 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4462 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004463
Georg Brandlba83f822010-03-14 09:50:54 +00004464- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4465 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004466
Georg Brandlba83f822010-03-14 09:50:54 +00004467- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4468 1e-100 used to raise OverflowError, but now gives the requested 120
4469 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004470

4476 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004477
Georg Brandlba83f822010-03-14 09:50:54 +00004478- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4479 decimal string that's guaranteed to round back to x under correct rounding
4480 (with round-half-to-even rounding mode). Previously it gave a string based on
4481 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4482 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4483 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004484
Georg Brandlba83f822010-03-14 09:50:54 +00004485- Issue #7117: On almost all platforms: float-to-string and string-to-float
4486 conversions within Python are now correctly rounded. Places these conversions
4487 occur include: str for floats and complex numbers; the float and complex
4488 constructors; old-style and new-style numeric formatting; serialization and
4489 deserialization of floats and complex numbers using marshal, pickle and json;
4490 parsing of float and imaginary literals in Python code; Decimal-to-float
4491 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004492
Georg Brandlba83f822010-03-14 09:50:54 +00004493 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4494 providing correctly-rounded strtod and dtoa C functions. This code is
4495 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4496 the C compiler. There may be a small number of platforms on which correct
4497 operation of this code cannot be guaranteed, so the code is not used: notably,
4498 this applies to platforms where the C double format is not IEEE 754 binary64,
4499 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4500 and Python's configure script is unable to determine how to change the FPU
4501 precision. On these platforms conversions use the platform strtod and dtoa,
4502 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004503
Georg Brandlba83f822010-03-14 09:50:54 +00004504- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4505 uses the correctly-rounded string <-> float conversions described above (when
4506 available), and so produces correctly rounded results that will display nicely
4507 under the float repr. There are two related small changes: (1) round now
4508 accepts any class with an ``__index__()`` method for its second argument (but
4509 no longer accepts floats for the second argument), and (2) an excessively
4510 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4511 raises an exception.

4514
Georg Brandlba83f822010-03-14 09:50:54 +00004515- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00004654 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4655 (2) parsing of strings representing infinities and nans was locale aware; and
4656 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004658- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4659 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4660 but with at least one decimal point and with a default precision
4661 of 12. Previously, the behavior the same but with a default precision of 6.
4662 This more closely matches ``str()``, and reduces surprises when adding
4663 alignment flags to the empty presentation type. This also affects the new
4664 complex.__format__ in the same way.
4665
4666- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4667 classtype's, even if it was None. property now inserts the __doc__ into the
4668 subclass instance __dict__.

4895 eventual KeyError would always report the empty ``frozenset()`` as the missing

Georg Brandlba83f822010-03-14 09:50:54 +00006153 leak-chasing test runs give sensible results. The previous method of reaping
6154 threads could return successfully while some Thread objects were still

Georg Brandl2bd92a52009-10-11 21:10:07 +00006275- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00006276 AttributeError instead of RuntimeError, depending in which C API call
6277 exactly the recursion limit is exceeded. Consequently, both exception types
6278 are caught and silenced.

6294
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006295- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6296
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006297- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6298 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6299 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6300 ``printf`` function, whereas PyString_FromFormat has an independent
6301 implementation and uses "%zd" on all platforms for size_t values.
6302 This makes a difference on win64, where ``printf`` needs "%Id" to display
6303 64bit values.
6304
Benjamin Peterson97179b02008-09-09 20:55:01 +00006305- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6306 error.
6307
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006308- Issue #3777: long() applied to a float object now always return a long
6309 object; previously an int would be returned for small values. the __long__
6310 method is allowed to return either an int or a long, but the behaviour of
6311 float objects should not change to respect backward compatibility.
6312
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006313- Issue #3751: str.rpartition would perform a left-partition when called with
6314 a unicode argument.
6315
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006316- Issue #3683: Fix compilation when --without-threads is given.
6317
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006318- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006319 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006320 was correctly parsed but parsing of subsequent arguments failed.
6321
Vinay Sajip35e3b032008-09-01 14:33:59 +00006322- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006323 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6324 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6325 when given a tuple of classes as second argument, were looking up
6326 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6327 type object.
6328
Neal Norwitz18aa3882008-08-24 05:04:52 +00006329- Fix crashes on memory allocation failure found with failmalloc.
6330
6331- Fix memory leaks found with valgrind and update suppressions file.
6332
6333- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6334
6335- Fix problem using wrong name in decimal module reported by pychecker.
6336
Christian Heimes7d4c3172008-08-22 19:47:25 +00006337- Silenced another compiler warning about a used but not defined
6338 function 'stringlib_contains_obj'.
6339
Benjamin Peterson712ee922008-08-24 18:10:20 +00006340- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6341 ``__delslice__``.
6342
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006343- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6344 library targets in the Makefile.
6345
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006346- Issue #1204: The configure script now tests for additional libraries
6347 that may be required when linking against readline. This fixes issues
6348 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00006372 return a list or None rather than a custom object.
6373
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00006374- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Georg Brandl222e2082010-08-01 22:27:39 +00006397- Issue #3602: Moved test.test_support.catch_warning() to
Brett Cannon1eaf0742008-09-02 01:25:16 +00006398 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6399 for catch_warnings() also led to an improvement in the raising of a
6400 DeprecationWarning related to warnings.warn_explicit().
6401
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006402- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006425- Issue #2975: When compiling several extension modules with Visual Studio 2008
6426 from the same python interpreter, some environment variables would grow
6427 without limit.
6428
Benjamin Peterson37346b22008-08-23 20:27:43 +00006429- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006466What's New in Python 2.6 beta 3?
6467================================
6468
Barry Warsaw07a4a382008-08-21 01:15:08 +00006469*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006470
6471Core and Builtins
6472-----------------
6473
Guido van Rossumf8402962008-08-20 15:01:50 +00006474- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6475 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6476 extensions do not automatically benefit from the class attribute
6477 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6478 to their tp_flags field if they care. This is a backwards
6479 compatibility feature; in 3.0, all types will use the cache by
6480 default.
6481
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006482- Keyword arguments can now follow starred arguments. (``f(a, *args,
6483 keyword=23)`` is now valid syntax.)
6484
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006485- ctypes function pointers that are COM methods have a boolean True
6486 value again.
6487
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006488- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6489 by denying s# to parse objects that have a releasebuffer procedure,
6490 and introducing s*.
6491
Georg Brandl1e13ea92008-08-11 09:07:59 +00006492- Issue #3537: Fix an assertion failure when an empty but presized dict
6493 object was stored in the freelist.
6494
Mark Dickinsonb6467572008-08-04 21:30:09 +00006495- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6496 ValueError consistently across platforms.
6497
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006498- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6499 (64bit Unix, for example), unichr() would truncate its argument and return
6500 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6501
Neal Norwitze7d8be82008-07-31 17:17:14 +00006502- Apply security patches from Apple.
6503
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006504- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6505 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6506
Antoine Pitrou92f82162008-07-25 22:22:08 +00006507- Issue #1819: function calls with several named parameters are now on
6508 average 35% faster (as measured by pybench).
6509
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006510- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6511 the python debugger steps into a class statement: the free variables (local
6512 variables defined in an outer scope) would be deleted from the outer scope.
6513
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006514- Issue #2620: Overflow checking when allocating or reallocating memory
6515 was not always being done properly in some python types and extension
6516 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6517 all been updated to perform better checks and places in the code that
6518 would previously leak memory on the error path when such an allocation
6519 failed have been fixed.

6525
Benjamin Petersone977ad42008-08-20 01:42:01 +00006526- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6527 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6528
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006529- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6530 version reported by these tools does not necessarily follow the python
6531 version numbering scheme, so the module is less strict when parsing it.
6532
Nick Coghlanf70385a2008-08-18 12:42:46 +00006533- Issue #2235: Added Py3k warnings for types which will become unhashable
6534 under the stricter __hash__ inheritance rules in 3.0. Several types
6535 which did not meet the rules for hash invariants and were already
6536 unhashable in 3.0 have now been explicitly flagged as unhashable in
6537 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6538 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6539
Brett Cannon88f801d2008-08-18 00:46:22 +00006540- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6541 imported into the module but exposed as part of the module's API.
6542
Brett Cannon7b96f072008-08-18 00:41:11 +00006543- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006547- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6548
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006549- Issue #3575: Incremental decoder's decode function now takes bytearray
6550 by using 's*' instead of 't#'.
6551
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006552- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006553 fails unicode conversion on 2nd parameter. (windows only)

Antoine Pitroude781a42008-08-09 12:43:23 +00006609 asking for a specific length. This problem only affected files opened

6653
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006654- Issue #643841: The language reference now provides more detailed

6666-----------------
6667
Georg Brandl3e483f62008-07-16 22:57:41 +00006668- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6669 its methods now allow for items objects that can be converted to
6670 an integer using operator.index().
6671
Mark Dickinson64b7e502008-07-16 09:40:03 +00006672- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6673 produced a ValueError instead of giving the correct float.
6674
Eric Smitha5fa5a22008-07-16 00:11:49 +00006675- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6676 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6677
Mark Dickinson7103aa42008-07-15 19:08:33 +00006678- Issue #3008: the float type has a new instance method 'float.hex'
6679 and a new class method 'float.fromhex' to convert floating-point
6680 numbers to and from hexadecimal strings, respectively.
6681
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006682- Issue #2235: __hash__ is once again inherited by default. To allow
6683 collections.Hashable to remain meaningful in the presence of the
6684 default hash implementation (object.__hash__), it is now possible
6685 to explicit block inheritance of hash by setting __hash__=None at
6686 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6687 level.
6688
Nick Coghlanb028f502008-07-13 14:52:36 +00006689- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6690 the parent module cannot be found while performing an absolute import.
6691 This means that an incorrectly defined __package__ attribute will
6692 now only prevent relative imports in that module rather than causing
6693 all imports from that module to fail.
6694
Nick Coghlan14ff9942008-07-08 14:21:42 +00006695- Issue #2517: Allow unicode messages in Exceptions again by correctly
6696 bypassing the instance dictionary when looking up __unicode__ on
6697 new-style classes.

6704 threading.local: the first member set by a thread could be saved in
6705 another thread's dictionary.
6706
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006707- Issue #3004: Minor change to slice.indices(): the start and stop
6708 arguments are now treated identically, making the behaviour easier
6709 to describe and understand. For example, slice(None, -10,
6710 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6711 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6712 10, -1).
6713
Georg Brandl278fc502008-07-19 12:46:12 +00006714- Issue #3219: Calling a function with repeated keyword arguments,
6715 f(a=2, a=23), would not cause a syntax error. This was a regression
6716 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006717
Georg Brandl278fc502008-07-19 12:46:12 +00006718- Issue #2862: Make int and float freelist management consistent with
6719 other freelists. Changes their CompactFreeList apis into

6726 api functions without holding the GIL, which could lead to a fatal
6727 error when they failed.
6728
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006729- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006754- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6755 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006756 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006757 content-length. The problem had been corrected in the 2.4 branch, but never
6758 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006773- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

6775
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006776- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

7163
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007164- On MacOS X it is now possible to install the framework in 64-bit
7165 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007166 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007167
7168 This is controlled by the configure argument ``--with-universal-archs``:
7169
7170 - ``--with-universal-archs=all``: install 4-way universal
7171
7172 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7173
7174 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7175
7176 This option should be used in combination with ``--enable-universalsdk=``.
7177
7178 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007228- Issue #1631171: Re-implement the 'warnings' module in C (the
7229 original Python code has been kept as backup). This will allow for
7230 using the 'warning's machinery in such places as the parser where
7231 use of pure Python code is not possible. Both the ``showarning()``
7232 and ``formatwarning()`` gain an optional 'line' argument which is
7233 not called by default for backwards-compatibility reasons. Setting
7234 ``warnings.showwarning()`` to an implementation that lacks support
7235 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007298- Issue #2550: The approach used by client/server code for obtaining
7299 ports to listen on in network-oriented tests has been refined in an
7300 effort to facilitate running multiple instances of the entire
7301 regression test suite in parallel without issue.
7302 test_support.bind_port() has been fixed such that it will always
7303 return a unique port -- which wasn't always the case with the
7304 previous implementation, especially if socket options had been set
7305 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7306 new implementation of bind_port() will actually raise an exception
7307 if it is passed an AF_INET/SOCK_STREAM socket with either the
7308 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7309 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7310 the socket it's been passed. This currently only applies to
7311 Windows. This option prevents any other sockets from binding to the
7312 host/port we've bound to, thus removing the possibility of the
7313 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7314 when a second SOCK_STREAM socket binds and accepts to a host/port
7315 that's already been bound by another socket. The optional preferred
7316 port parameter to bind_port() has been removed. Under no
7317 circumstances should tests be hard coding ports!
7318
7319 test_support.find_unused_port() has also been introduced, which will
7320 pass a temporary socket object to bind_port() in order to obtain an
7321 unused port. The temporary socket object is then closed and
7322 deleted, and the port is returned. This method should only be used
7323 for obtaining an unused port in order to pass to an external program
7324 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7325 a parameter to a server-oriented class that doesn't give you direct
7326 access to the underlying socket used.
7327
7328 Finally, test_support.HOST has been introduced, which should be used
7329 for the host argument of any relevant socket calls (i.e. bind and
7330 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007331
7332 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007333 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007334 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7335 test_asynchat and test_socket_ssl.
7336
Georg Brandl3ee81df2008-05-17 18:14:43 +00007337 It is now possible for multiple instances of the regression test
7338 suite to run in parallel without issue.

7396 this case, like normal unicode literals and the 'unicode-escape'
7397 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00007617- Added the future_builtins module, which contains hex() and oct().
7618 These are the PEP 3127 version of these functions, designed to be
7619 compatible with the hex() and oct() builtins from Python 3.0. They
7620 differ slightly in their output formats from the existing, unchanged
7621 Python 2.6 builtins. The expected usage of the future_builtins
7622 module is:
7623 from future_builtins import hex, oct
7624
Eric Smith7ef40bf2008-02-20 23:34:22 +00007625- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7626 exponents for exponents with absolute value < 100. Follows C99
7627 standard. This is a change on Windows, which would use 3 digits.
7628 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7629 so that any alterations it does to the resulting string will be
7630 available in stringlib/formatter.h (for float.__format__).
7631
Eric Smith5a3c1352008-02-19 13:21:56 +00007632- Implemented PEP 3101, Advanced String Formatting. This adds a new
7633 builtin format(); a format() method for str and unicode; a
7634 __format__() method to object, str, unicode, int, long, float, and
7635 datetime; the class string.Formatter; and the C API
7636 PyObject_Format().
7637
Georg Brandl3ee81df2008-05-17 18:14:43 +00007638- Fixed several potential crashes, all caused by specially crafted
7639 __del__ methods exploiting objects in temporarily inconsistent
7640 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007649- Clear all free lists during a gc.collect() of the highest generation
7650 in order to allow pymalloc to free more arenas. Python may give back
7651 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007652
Georg Brandl3ee81df2008-05-17 18:14:43 +00007653- Issue #2045: Fix an infinite recursion triggered when printing a
7654 subclass of collections.defaultdict, if its default_factory is set
7655 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007683- Patch #1473257: generator objects gain a gi_code attribute. This is
7684 the same object as the func_code attribute of the function that
7685 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007686
Georg Brandl3ee81df2008-05-17 18:14:43 +00007687- Issue #1920: "while 0" statements were completely removed by the
7688 compiler, even in the presence of an "else" clause, which is
7689 supposed to be run when the condition is false. Now the compiler
7690 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007691
Guido van Rossumeead05f2008-01-24 18:21:02 +00007692- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007696- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007697 suppressed while an extension is loaded by calling SetErrorMode in

7699
Georg Brandl3ee81df2008-05-17 18:14:43 +00007700- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007701 several extension methods and modules do not work without unicode
7702 support.
7703

7708
Georg Brandl6caad7d2008-01-26 14:19:22 +00007709- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007710 added.
7711
Christian Heimesc94e2b52008-01-14 04:13:37 +00007712- sys.float_info / PyFloat_GetInfo: The floating point information
7713 object was converted from a dict to a specialized structseq object.
7714
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715- Patch #1816: Added sys.flags structseq. It exposes the status of
7716 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007717
Georg Brandl3ee81df2008-05-17 18:14:43 +00007718- Objects/structseq.c: Implemented new structseq representation. The
7719 patch makes structseqs (e.g. the return value of os.stat) more
7720 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007721
Georg Brandl3ee81df2008-05-17 18:14:43 +00007722- Patch #1700288: added a type attribute cache that caches method
7723 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007724
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007725- Bug #1776: __import__() no longer accepts filenames on any platform.
7726 The first parameter to __import__() must be a valid module name.

7731 envvar and sys.dont_write_bytecode attribute. All these can be set
7732 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007733
Georg Brandl3ee81df2008-05-17 18:14:43 +00007734- Improve some exception messages when Windows fails to load an
7735 extension module. Now we get for example '%1 is not a valid Win32
7736 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007743- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007744 and INF. float("nan"), float("inf") and float("-inf") now work on
7745 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007746
Georg Brandl3ee81df2008-05-17 18:14:43 +00007747- Compiler now generates simpler and faster code for dictionary
7748 literals. The oparg for BUILD_MAP now indicates an estimated
7749 dictionary size. There is a new opcode, STORE_MAP, for adding
7750 entries to the dictionary.

7780 file can now be directly executed by passing their name to the
7781 interpreter. The directory/zipfile is automatically inserted as the
7782 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007784- Issue #1265: Fix a problem with sys.settrace, if the tracing
7785 function uses a generator expression when at the same time the
7786 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007787
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007788- sets and frozensets now have an isdisjoint() method.
7789
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007790- optimize the performance of builtin.sum().

7793
Georg Brandl21e99f42010-03-07 15:23:59 +00007794- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007795 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7796 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007797
Georg Brandl3ee81df2008-05-17 18:14:43 +00007798- Issue #1686386: Tuple's tp_repr did not take into account the
7799 possibility of having a self-referential tuple, which is possible
7800 from C code. Nor did object's tp_str consider that a type's tp_str
7801 could do something that could lead to an inifinite recursion.
7802 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7803 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007804
Georg Brandl3ee81df2008-05-17 18:14:43 +00007805- Issue #1164: It was possible to trigger deadlock when using the
7806 'print' statement to write to a file since the GIL was not released
7807 as needed. Now PyObject_Print() does the right thing along with
7808 various tp_print implementations of the built-in types and those in
7809 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007810
Georg Brandl3ee81df2008-05-17 18:14:43 +00007811- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00007818- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007819 PyObject_Call() never calling back out to Python code to trigger
7820 recursion depth updates/checks. Required the creation of a static
7821 RuntimeError instance in case normalizing an exception put the
7822 recursion check value past its limit. Fixes crashers
7823 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007824

Neal Norwitz0ac60192007-05-27 04:08:54 +00007838- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007839 __*__ attributes. (Some already existed, e.g., __doc__ and
7840 __name__.)

7844
Georg Brandl2134e752007-05-21 20:34:16 +00007845- Patch #1686487: you can now pass any mapping after '**' in function
7846 calls.
7847
Collin Winter62903052007-05-18 23:11:24 +00007848- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007849 "except E as target:". This is to provide forwards compatibility
7850 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007857- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007858 setting a plain string, ie don't expand to single letter identifiers.
7859
Raymond Hettinger13936692007-04-11 18:40:58 +00007860- Request #1191699: Slices can now be pickled.
7861
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007862- Request #1193128: str.translate() now allows a None argument for
7863 translations that only remove characters without re-mapping the
7864 remaining characters.
7865
Georg Brandl5cb76c12007-03-21 09:00:39 +00007866- Patch #1682205: a TypeError while unpacking an iterable is no longer

7870
Guido van Rossum143b5642007-03-23 04:58:42 +00007871- Bug #1683368: The object.__init__() and object.__new__() methods are
7872 now stricter in rejecting excess arguments. The only time when
7873 either allows excess arguments is when it is not overridden and the
7874 other one is. For backwards compatibility, when both are
7875 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007876 warning later). Also, type.__init__() insists on the same signature
7877 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007879- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7880 object to complex using its __complex__() method before falling back
7881 to the __float__() method. Therefore, the functions in the cmath
7882 module now can operate on objects that define a __complex__()
7883 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007905 its argument, if it exists. If not, it will work like before. This
7906 allows customizing the output of dir() in the presence of a
7907 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00007919- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00007989- Bug #1545497: when given an explicit base, int() did ignore NULs
7990 embedded in the string to convert.
7991
Georg Brandl846f73a2006-10-08 07:11:54 +00007992- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00008040 generator expressions (x for x, in ... ) works again. Fixing this
8041 problem required changing the .pyc magic number. This means that
8042 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008951 time so that opening a database previously created with the DB_DUP
8952 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8953 opens. Specifically: dictionary assignment to a DB object will
8954 replace all values for a given key when the database allows
8955 duplicate values. DB users should use DB.put(k, v) when they want
8956 to store duplicates; not DB[k] = v.

8963 characters with ASCII value less than 32. Also, it correctly quotes
8964 dots only if they occur on a single line, as opposed to the previous
8965 behavior of quoting dots if they are the second character of any
8966 line.
