1544 In particular, fix extension module build failures when trying to use
1545 32-bit-only installer Pythons on systems with Xcode 4 (currently
1546 OS X 10.8, 10.7, and optionally 10.6).
1547 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1548 * Since Xcode 4 removes ppc support, extension module builds now
1549 check for ppc compiler support and by default remove ppc and
1550 ppc64 archs when they are not available.
1551 * Extension module builds now revert to using system installed
1552 headers and libs (/usr and /System/Library) if the SDK used
1553 to build the interpreter is not installed or has moved.
1554 * Try to avoid building extension modules with deprecated
1555 and problematic Apple llvm-gcc compiler. If original compiler
1556 is not available, use clang instead by default.

1988 Distutils-based packages with C extension modules may fail because
1989 Apple has removed gcc-4.2, the version used to build python.org
1990 64-bit/32-bit Pythons. If the user does not explicitly override
1991 the default C compiler by setting the CC environment variable,
1992 Distutils will now attempt to compile extension modules with clang
1993 if gcc-4.2 is required but not found. Also as a convenience, if
1994 the user does explicitly set CC, substitute its value as the default
1995 compiler in the Distutils LDSHARED configuration variable for OS X.
1996 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1997 SDK, neither of which are available in Xcode 4. This change does not
1998 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002248- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2249 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2250 interpreter process. This could cause failures in non-Distutils subprocesses
2251 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002252 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002253 deployment target only in the environment of each build subprocess. It is
2254 still possible to globally override the default by setting
2255 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2256 greater or equal to the default value, the value with which the interpreter
2257 was built.

2287 the ticker doesn't have to wind down to zero from the old starting point
2288 before the new interval takes effect. And if the user increases the
2289 interval, it makes sure the new limit takes effect right away rather have an
2290 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003270- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3271 This prevents user-created self-referencing ordered dictionaries from
3272 becoming permanently uncollectable GC garbage. The downside is that
3273 removing __del__ means that the internal doubly-linked list has to wait for
3274 GC collection rather than freeing memory immediately when the refcnt drops
3275 to zero.
3276

3284 original error is re-raised.

3305
R. David Murray7c4bf552010-08-25 01:45:57 +00003306- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3307 character years even if the message contains RFC822 two character years.

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003341- Issue #9550: a BufferedReader could issue an additional read when the
3342 original read request had been satisfied, which could block indefinitely
3343 when the underlying raw IO channel was e.g. a socket. Report and original
3344 patch by Jason V. Miller.

3735 of the number of bytes specified by the start byte.
3736 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3737 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3749 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

4118
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004119- Issue #7301: Add environment variable $PYTHONWARNINGS.
4120
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004121- Issue #8329: Don't return the same lists from select.select when no fds are
4122 changed.
4123
Georg Brandlfee0f442010-05-22 21:26:21 +00004124- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004125 on 64-bit machines. The shift count for either left or right shift is
4126 permitted to be up to sys.maxsize.
4127
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004128- Ensure that tokenization of identifiers is not affected by locale.

4133
Georg Brandlfee0f442010-05-22 21:26:21 +00004134- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4135 with a non-empty format string. This is an effort to future-proof user
4136 code. If a derived class does not currently implement __format__ but later
4137 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004138 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004139 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004172- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00004189- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4190 InvalidOperation instead of returning False. (Comparisons involving a quiet
4191 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4192 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004193
Georg Brandlfee0f442010-05-22 21:26:21 +00004194- Issue #2531: Comparison operations between floats and Decimal instances now
4195 return a result based on the numeric values of the operands; previously they
4196 returned an arbitrary result based on the relative ordering of id(float) and
4197 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004199- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004200 argument `-` which tells it to read files to compile from stdin. Each line is
4201 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00004211- Comparisons using one of <, <=, >, >= between a complex instance and a
4212 Fractions instance now raise TypeError instead of returning True/False. This
4213 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4214 <=> complex, and complex <=> complex comparisons.

4323 the set of integer codes for which it was used differed between native packing
4324 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004632 file position when calling `truncate()`. It would previously change the file
4633 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004634 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4637 class used to represent files stored inside an archive. The new
4638 implementation is significantly faster and can be wrapped in a

4640 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4653 encoded string for them. This ensures that the upload and register commands
4654 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004731- The ``__complex__()`` method is now looked up on the class of instances to
4732 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004734- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4735 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4736
Mark Dickinson1b34d252010-01-01 17:27:30 +00004737- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004738 DeprecationWarning when passed a float argument where an integer was expected.
4739 These functions and methods now raise TypeError instead. The majority of the
4740 effects of this change are in the extension modules, but some core functions
4741 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4742 and many unicode/str methods.

Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +00004751
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00004752- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
4753 used to drop the time part of the result.
4754
Georg Brandlba83f822010-03-14 09:50:54 +00004755- Issue #1811: Improve accuracy and cross-platform consistency for true division
4756 of integers: the result of a/b is now correctly rounded for ints a and b (at
4757 least on IEEE 754 platforms), and in particular does not depend on the
4758 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004759
Georg Brandlba83f822010-03-14 09:50:54 +00004760- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4761 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4762 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00004763

Ronald Oussoren92919a62009-12-24 13:30:58 +00004765 executables on OSX.
4766
Georg Brandlba83f822010-03-14 09:50:54 +00004767 These executables now work properly with the arch(1) command: ``arch -ppc
4768 python`` will start a universal binary version of python in PPC mode (unlike
4769 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00004770
Georg Brandlba83f822010-03-14 09:50:54 +00004771- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
4772 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00004773

Georg Brandlba83f822010-03-14 09:50:54 +00004782- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
4783 allowing for a maximum number of tasks within the pool to be completed by the
4784 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00004790- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00004791 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
4792 alternative to cPickle if you care about performance. Patch by Florent

4829 the same as passing no argument.
4830
Georg Brandlba83f822010-03-14 09:50:54 +00004831- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

4855 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept

Georg Brandlba83f822010-03-14 09:50:54 +00004924- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4925 decimal string that's guaranteed to round back to x under correct rounding
4926 (with round-half-to-even rounding mode). Previously it gave a string based on
4927 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4928 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4929 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004930
Georg Brandlba83f822010-03-14 09:50:54 +00004931- Issue #7117: On almost all platforms: float-to-string and string-to-float
4932 conversions within Python are now correctly rounded. Places these conversions
4933 occur include: str for floats and complex numbers; the float and complex
4934 constructors; old-style and new-style numeric formatting; serialization and
4935 deserialization of floats and complex numbers using marshal, pickle and json;
4936 parsing of float and imaginary literals in Python code; Decimal-to-float
4937 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004938
Georg Brandlba83f822010-03-14 09:50:54 +00004939 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4940 providing correctly-rounded strtod and dtoa C functions. This code is
4941 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4942 the C compiler. There may be a small number of platforms on which correct
4943 operation of this code cannot be guaranteed, so the code is not used: notably,
4944 this applies to platforms where the C double format is not IEEE 754 binary64,
4945 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4946 and Python's configure script is unable to determine how to change the FPU
4947 precision. On these platforms conversions use the platform strtod and dtoa,
4948 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004950- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4951 uses the correctly-rounded string <-> float conversions described above (when
4952 available), and so produces correctly rounded results that will display nicely
4953 under the float repr. There are two related small changes: (1) round now
4954 accepts any class with an ``__index__()`` method for its second argument (but
4955 no longer accepts floats for the second argument), and (2) an excessively
4956 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4957 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004961- Fix several issues with ``compile()``. The input can now contain Windows and

5307
Georg Brandlba83f822010-03-14 09:50:54 +00005308- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on

Georg Brandlba83f822010-03-14 09:50:54 +00005334- On windows, ``os.chdir()`` given unicode was not working if

5336 this code path is really executed because I cannot move to such directory on
5337 win2k)

5363 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Walter Dörwald726ba8e2009-05-06 14:32:35 +00005367- Issue #3739: The unicode-internal encoder now reports the number of characters

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006743- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6744 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6745 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6746 ``printf`` function, whereas PyString_FromFormat has an independent
6747 implementation and uses "%zd" on all platforms for size_t values.
6748 This makes a difference on win64, where ``printf`` needs "%Id" to display
6749 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00006769 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

6773 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006844 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6845 for catch_warnings() also led to an improvement in the raising of a
6846 DeprecationWarning related to warnings.warn_explicit().
6847
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006848- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006912What's New in Python 2.6 beta 3?
6913================================
6914
Barry Warsaw07a4a382008-08-21 01:15:08 +00006915*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006916
6917Core and Builtins
6918-----------------
6919
Guido van Rossumf8402962008-08-20 15:01:50 +00006920- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6921 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6922 extensions do not automatically benefit from the class attribute
6923 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6924 to their tp_flags field if they care. This is a backwards
6925 compatibility feature; in 3.0, all types will use the cache by
6926 default.
6927
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006928- Keyword arguments can now follow starred arguments. (``f(a, *args,
6929 keyword=23)`` is now valid syntax.)
6930
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006931- ctypes function pointers that are COM methods have a boolean True
6932 value again.
6933
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006934- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6935 by denying s# to parse objects that have a releasebuffer procedure,
6936 and introducing s*.
6937
Georg Brandl1e13ea92008-08-11 09:07:59 +00006938- Issue #3537: Fix an assertion failure when an empty but presized dict
6939 object was stored in the freelist.
6940
Mark Dickinsonb6467572008-08-04 21:30:09 +00006941- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6942 ValueError consistently across platforms.
6943
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006944- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6945 (64bit Unix, for example), unichr() would truncate its argument and return
6946 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6947
Neal Norwitze7d8be82008-07-31 17:17:14 +00006948- Apply security patches from Apple.
6949
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006950- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6951 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6952
Antoine Pitrou92f82162008-07-25 22:22:08 +00006953- Issue #1819: function calls with several named parameters are now on
6954 average 35% faster (as measured by pybench).
6955
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006956- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6957 the python debugger steps into a class statement: the free variables (local
6958 variables defined in an outer scope) would be deleted from the outer scope.
6959
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006960- Issue #2620: Overflow checking when allocating or reallocating memory
6961 was not always being done properly in some python types and extension
6962 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6963 all been updated to perform better checks and places in the code that
6964 would previously leak memory on the error path when such an allocation
6965 failed have been fixed.

6968-------
6969
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006970- Issue #3612: Added some missing basic types in ctypes.wintypes.
6971
Benjamin Petersone977ad42008-08-20 01:42:01 +00006972- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6973 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6974
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006975- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6976 version reported by these tools does not necessarily follow the python
6977 version numbering scheme, so the module is less strict when parsing it.
6978
Nick Coghlanf70385a2008-08-18 12:42:46 +00006979- Issue #2235: Added Py3k warnings for types which will become unhashable
6980 under the stricter __hash__ inheritance rules in 3.0. Several types
6981 which did not meet the rules for hash invariants and were already
6982 unhashable in 3.0 have now been explicitly flagged as unhashable in
6983 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6984 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6985
Brett Cannon88f801d2008-08-18 00:46:22 +00006986- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6994
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006995- Issue #3575: Incremental decoder's decode function now takes bytearray
6996 by using 's*' instead of 't#'.
6997
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006998- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006999 fails unicode conversion on 2nd parameter. (windows only)
7000
Georg Brandl222e2082010-08-01 22:27:39 +00007001- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007002 in a redirect.
7003
Brett Cannonabe423e2008-08-16 21:47:07 +00007004- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007005 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007006
Facundo Batistaeb90b782008-08-16 14:44:07 +00007007- Issue #2776: fixed small issue when handling an URL with double slash
7008 after a 302 response in the case of not going through a proxy.
7009
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007010- Issue #2676: in the email package, content-type parsing was hanging on
7011 pathological input because of quadratic or exponential behaviour of a
7012 regular expression.
7013
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007014- Issue #3476: binary buffered reading through the new "io" library is now
7015 thread-safe.
7016
Brett Cannonbf3157b2008-08-14 05:00:03 +00007017- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7018 since mimetools itself is deprecated. Because modules are cached, all
7019 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7020
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007021- Issue #3134: shutil referenced undefined WindowsError symbol.
7022
Robert Schuppenies14646332008-08-10 11:01:53 +00007023- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7024 menu entries were not deleted.
7025
Brett Cannon83e81842008-08-09 23:30:55 +00007026- Copied the implementation of reduce() to _functools.reduce() to have a
7027 version that did not raise a DeprecationWarning under -3.
7028
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007029- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7030 a MemoryError rather than silently stop the iteration.
7031
Guido van Rossum59ce9012008-08-09 14:55:34 +00007032- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7033 to _sre.compile() will now be rejected. This should not affect anybody
7034 since the re.compile() function never generates invalid re-bytecode.
7035
Skip Montanaroa032bf42008-08-08 22:52:51 +00007036- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7037 upon first access it can be automatically initialized from the csv file if
7038 it wasn't initialized during instantiation.
7039
Brett Cannon3aa2a492008-08-06 22:28:09 +00007040- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7041 the reload() built-in has been removed.
7042
Brett Cannon7e30b672008-08-04 21:52:25 +00007043- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007044 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007055 asking for a specific length. This problem only affected files opened
7056 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007057

7116 an integer using operator.index().
7117
Mark Dickinson64b7e502008-07-16 09:40:03 +00007118- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7119 produced a ValueError instead of giving the correct float.
7120
Eric Smitha5fa5a22008-07-16 00:11:49 +00007121- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7122 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7123
Mark Dickinson7103aa42008-07-15 19:08:33 +00007124- Issue #3008: the float type has a new instance method 'float.hex'
7125 and a new class method 'float.fromhex' to convert floating-point
7126 numbers to and from hexadecimal strings, respectively.
7127
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007128- Issue #2235: __hash__ is once again inherited by default. To allow
7129 collections.Hashable to remain meaningful in the presence of the
7130 default hash implementation (object.__hash__), it is now possible
7131 to explicit block inheritance of hash by setting __hash__=None at
7132 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7133 level.
7134
Nick Coghlanb028f502008-07-13 14:52:36 +00007135- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7136 the parent module cannot be found while performing an absolute import.
7137 This means that an incorrectly defined __package__ attribute will
7138 now only prevent relative imports in that module rather than causing
7139 all imports from that module to fail.
7140
Nick Coghlan14ff9942008-07-08 14:21:42 +00007141- Issue #2517: Allow unicode messages in Exceptions again by correctly

7151 another thread's dictionary.
7152
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007153- Issue #3004: Minor change to slice.indices(): the start and stop
7154 arguments are now treated identically, making the behaviour easier
7155 to describe and understand. For example, slice(None, -10,
7156 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7157 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7158 10, -1).
7159
Georg Brandl278fc502008-07-19 12:46:12 +00007160- Issue #3219: Calling a function with repeated keyword arguments,
7161 f(a=2, a=23), would not cause a syntax error. This was a regression
7162 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007200- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7201 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007202 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007203 content-length. The problem had been corrected in the 2.4 branch, but never

Georg Brandl3ee81df2008-05-17 18:14:43 +00007671- Issue #1631171: Re-implement the 'warnings' module in C (the
7672 original Python code has been kept as backup). This will allow for
7673 using the 'warning's machinery in such places as the parser where
7674 use of pure Python code is not possible. Both the ``showarning()``
7675 and ``formatwarning()`` gain an optional 'line' argument which is
7676 not called by default for backwards-compatibility reasons. Setting
7677 ``warnings.showwarning()`` to an implementation that lacks support
7678 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007741- Issue #2550: The approach used by client/server code for obtaining
7742 ports to listen on in network-oriented tests has been refined in an
7743 effort to facilitate running multiple instances of the entire
7744 regression test suite in parallel without issue.
7745 test_support.bind_port() has been fixed such that it will always
7746 return a unique port -- which wasn't always the case with the
7747 previous implementation, especially if socket options had been set
7748 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7749 new implementation of bind_port() will actually raise an exception
7750 if it is passed an AF_INET/SOCK_STREAM socket with either the
7751 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7752 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7753 the socket it's been passed. This currently only applies to
7754 Windows. This option prevents any other sockets from binding to the
7755 host/port we've bound to, thus removing the possibility of the
7756 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7757 when a second SOCK_STREAM socket binds and accepts to a host/port
7758 that's already been bound by another socket. The optional preferred
7759 port parameter to bind_port() has been removed. Under no
7760 circumstances should tests be hard coding ports!
7761
7762 test_support.find_unused_port() has also been introduced, which will
7763 pass a temporary socket object to bind_port() in order to obtain an
7764 unused port. The temporary socket object is then closed and
7765 deleted, and the port is returned. This method should only be used
7766 for obtaining an unused port in order to pass to an external program
7767 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7768 a parameter to a server-oriented class that doesn't give you direct
7769 access to the underlying socket used.
7770
7771 Finally, test_support.HOST has been introduced, which should be used
7772 for the host argument of any relevant socket calls (i.e. bind and
7773 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007774
7775 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007776 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007777 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7778 test_asynchat and test_socket_ssl.
7779
Georg Brandl3ee81df2008-05-17 18:14:43 +00007780 It is now possible for multiple instances of the regression test
7781 suite to run in parallel without issue.

Marc-André Lemburga1867752008-03-20 18:08:00 +00007938 platform.machine() and platform.processor() will report this
7939 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00008060- Added the future_builtins module, which contains hex() and oct().
8061 These are the PEP 3127 version of these functions, designed to be
8062 compatible with the hex() and oct() builtins from Python 3.0. They
8063 differ slightly in their output formats from the existing, unchanged
8064 Python 2.6 builtins. The expected usage of the future_builtins
8065 module is:
8066 from future_builtins import hex, oct
8067
Eric Smith7ef40bf2008-02-20 23:34:22 +00008068- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8069 exponents for exponents with absolute value < 100. Follows C99
8070 standard. This is a change on Windows, which would use 3 digits.
8071 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8072 so that any alterations it does to the resulting string will be
8073 available in stringlib/formatter.h (for float.__format__).
8074
Eric Smith5a3c1352008-02-19 13:21:56 +00008075- Implemented PEP 3101, Advanced String Formatting. This adds a new
8076 builtin format(); a format() method for str and unicode; a
8077 __format__() method to object, str, unicode, int, long, float, and
8078 datetime; the class string.Formatter; and the C API
8079 PyObject_Format().
8080
Georg Brandl3ee81df2008-05-17 18:14:43 +00008081- Fixed several potential crashes, all caused by specially crafted
8082 __del__ methods exploiting objects in temporarily inconsistent
8083 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008084
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008085- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008086 prevent a possible crash: an Abstract Base Class would try to access
8087 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008088

Georg Brandl3ee81df2008-05-17 18:14:43 +00008092- Clear all free lists during a gc.collect() of the highest generation
8093 in order to allow pymalloc to free more arenas. Python may give back
8094 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008095
Georg Brandl3ee81df2008-05-17 18:14:43 +00008096- Issue #2045: Fix an infinite recursion triggered when printing a
8097 subclass of collections.defaultdict, if its default_factory is set
8098 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008099
Christian Heimesf75dbef2008-02-08 00:11:31 +00008100- Fixed a minor memory leak in dictobject.c. The content of the free
8101 list was not freed on interpreter shutdown.
8102
Georg Brandl21e99f42010-03-07 15:23:59 +00008103- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00008105
Georg Brandl3ee81df2008-05-17 18:14:43 +00008106- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8107 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008108 to compact the internal free lists of pre-allocted ints and floats.
8109
Georg Brandl3ee81df2008-05-17 18:14:43 +00008110- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8111 calls. Python expected the return type int but the fork familie
8112 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008113
Georg Brandl3ee81df2008-05-17 18:14:43 +00008114- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008126- Patch #1473257: generator objects gain a gi_code attribute. This is
8127 the same object as the func_code attribute of the function that
8128 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008129
Georg Brandl3ee81df2008-05-17 18:14:43 +00008130- Issue #1920: "while 0" statements were completely removed by the
8131 compiler, even in the presence of an "else" clause, which is
8132 supposed to be run when the condition is false. Now the compiler
8133 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008134
Guido van Rossumeead05f2008-01-24 18:21:02 +00008135- A few crashers fixed: weakref_in_del.py (issue #1377858);
8136 loosing_dict_ref.py (issue #1303614, test67.py);
8137 borrowed_ref_[34].py (not in tracker).
8138
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008139- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008140 suppressed while an extension is loaded by calling SetErrorMode in

8142
Georg Brandl3ee81df2008-05-17 18:14:43 +00008143- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008144 several extension methods and modules do not work without unicode
8145 support.
8146
Georg Brandl26543b12008-01-21 18:36:51 +00008147- Issue #1882: when compiling code from a string, encoding cookies in the
8148 second line of code were not always recognized correctly.
8149
Georg Brandl14404b62008-01-19 19:27:05 +00008150- Issue #1679: "0x" was taken as a valid integer literal.
8151
Georg Brandl6caad7d2008-01-26 14:19:22 +00008152- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008153 added.
8154
Christian Heimesc94e2b52008-01-14 04:13:37 +00008155- sys.float_info / PyFloat_GetInfo: The floating point information
8156 object was converted from a dict to a specialized structseq object.
8157
Georg Brandl3ee81df2008-05-17 18:14:43 +00008158- Patch #1816: Added sys.flags structseq. It exposes the status of
8159 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008160
Georg Brandl3ee81df2008-05-17 18:14:43 +00008161- Objects/structseq.c: Implemented new structseq representation. The
8162 patch makes structseqs (e.g. the return value of os.stat) more
8163 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008164
Georg Brandl3ee81df2008-05-17 18:14:43 +00008165- Patch #1700288: added a type attribute cache that caches method

8174 envvar and sys.dont_write_bytecode attribute. All these can be set
8175 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008176
Georg Brandl3ee81df2008-05-17 18:14:43 +00008177- Improve some exception messages when Windows fails to load an
8178 extension module. Now we get for example '%1 is not a valid Win32

Georg Brandl3ee81df2008-05-17 18:14:43 +00008190- Compiler now generates simpler and faster code for dictionary
8191 literals. The oparg for BUILD_MAP now indicates an estimated
8192 dictionary size. There is a new opcode, STORE_MAP, for adding
8193 entries to the dictionary.

8223 file can now be directly executed by passing their name to the
8224 interpreter. The directory/zipfile is automatically inserted as the
8225 first entry in sys.path.

8236
Georg Brandl21e99f42010-03-07 15:23:59 +00008237- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008238 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8239 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008240
Georg Brandl3ee81df2008-05-17 18:14:43 +00008241- Issue #1686386: Tuple's tp_repr did not take into account the
8242 possibility of having a self-referential tuple, which is possible
8243 from C code. Nor did object's tp_str consider that a type's tp_str
8244 could do something that could lead to an inifinite recursion.
8245 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8246 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008247
Georg Brandl3ee81df2008-05-17 18:14:43 +00008248- Issue #1164: It was possible to trigger deadlock when using the
8249 'print' statement to write to a file since the GIL was not released
8250 as needed. Now PyObject_Print() does the right thing along with
8251 various tp_print implementations of the built-in types and those in
8252 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00008261- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008262 PyObject_Call() never calling back out to Python code to trigger
8263 recursion depth updates/checks. Required the creation of a static
8264 RuntimeError instance in case normalizing an exception put the
8265 recursion check value past its limit. Fixes crashers
8266 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008281- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008282 __*__ attributes. (Some already existed, e.g., __doc__ and
8283 __name__.)

8289 calls.
8290
Collin Winter62903052007-05-18 23:11:24 +00008291- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008292 "except E as target:". This is to provide forwards compatibility
8293 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008300- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008301 setting a plain string, ie don't expand to single letter identifiers.
8302
Raymond Hettinger13936692007-04-11 18:40:58 +00008303- Request #1191699: Slices can now be pickled.
8304
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008305- Request #1193128: str.translate() now allows a None argument for
8306 translations that only remove characters without re-mapping the
8307 remaining characters.
8308
Georg Brandl5cb76c12007-03-21 09:00:39 +00008309- Patch #1682205: a TypeError while unpacking an iterable is no longer

8313
Guido van Rossum143b5642007-03-23 04:58:42 +00008314- Bug #1683368: The object.__init__() and object.__new__() methods are
8315 now stricter in rejecting excess arguments. The only time when
8316 either allows excess arguments is when it is not overridden and the
8317 other one is. For backwards compatibility, when both are
8318 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008319 warning later). Also, type.__init__() insists on the same signature
8320 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008321
Georg Brandl3ee81df2008-05-17 18:14:43 +00008322- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8323 object to complex using its __complex__() method before falling back
8324 to the __float__() method. Therefore, the functions in the cmath
8325 module now can operate on objects that define a __complex__()
8326 method.

8337 its type.

8343
Georg Brandl7b9c5552007-03-12 14:30:05 +00008344- Bug #1678647: write a newline after printing an exception in any
8345 case, even when converting the value to a string failed.
8346
Georg Brandl871f1bc2007-03-12 13:17:36 +00008347- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008348 its argument, if it exists. If not, it will work like before. This
8349 allows customizing the output of dir() in the presence of a
8350 __getattr__().

8354
Georg Brandl3ee81df2008-05-17 18:14:43 +00008355- Patch #1675981: remove unreachable code from ``type.__new__()``

8359 parthensized forms. This means complex(repr(x)) now works instead of
8360 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008361
Georg Brandlaa2321b2007-03-07 00:40:28 +00008362- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008363 makes the filenames the warning module prints much more sensible
8364 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008377- Patch #1674228: when assigning a slice (old-style), check for the
8378 sq_ass_slice instead of the sq_slice slot.
8379
Georg Brandl3ee81df2008-05-17 18:14:43 +00008380- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00008949 are set for invalid interpolation sequences that would lead to

9006 TestCase and TestSuite subclasses (not instances) are no longer
9007 accepted in TestSuite.addTest(). This should cause no
9008 incompatibility since it never made sense with ordinary subclasses
9009 -- the failure just occurred later, with a more cumbersome
9010 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009291 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00009293 does not claim to support starttls. Adds the
9294 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009392- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009393 time so that opening a database previously created with the DB_DUP
9394 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9395 opens. Specifically: dictionary assignment to a DB object will
9396 replace all values for a given key when the database allows
9397 duplicate values. DB users should use DB.put(k, v) when they want
9398 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009399

9406 dots only if they occur on a single line, as opposed to the previous
9407 behavior of quoting dots if they are the second character of any
9408 line.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009683- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00009684 periodic threadstate and signal checking in tight loops. By
9685 default, this option is turned-off. It should only be enabled in
9686 debugged, performance critical applications.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009743- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9744 to ``PyTuple_SetItem``, it can be used to populate a brand new
9745 frozenset; but it does not steal a reference to the added item.

9759 of w# format code incorrectly truncated the length to an int, even
9760 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9761 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009762

Georg Brandl3ee81df2008-05-17 18:14:43 +00009791- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9792 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009793
Georg Brandl3ee81df2008-05-17 18:14:43 +00009794- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
