Ned Deily18fae3f2013-01-31 01:24:55 -0800757- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
758 In particular, fix extension module build failures when trying to use
759 32-bit-only installer Pythons on systems with Xcode 4 (currently
760 OS X 10.8, 10.7, and optionally 10.6).
761 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
762 * Since Xcode 4 removes ppc support, extension module builds now
763 check for ppc compiler support and by default remove ppc and
764 ppc64 archs when they are not available.
765 * Extension module builds now revert to using system installed
766 headers and libs (/usr and /System/Library) if the SDK used
767 to build the interpreter is not installed or has moved.
768 * Try to avoid building extension modules with deprecated
769 and problematic Apple llvm-gcc compiler. If original compiler
770 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01001095- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1096 Distutils-based packages with C extension modules may fail because
1097 Apple has removed gcc-4.2, the version used to build python.org
1098 64-bit/32-bit Pythons. If the user does not explicitly override
1099 the default C compiler by setting the CC environment variable,
1100 Distutils will now attempt to compile extension modules with clang
1101 if gcc-4.2 is required but not found. Also as a convenience, if
1102 the user does explicitly set CC, substitute its value as the default
1103 compiler in the Distutils LDSHARED configuration variable for OS X.
1104 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1105 SDK, neither of which are available in Xcode 4. This change does not
1106 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001379- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1380 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1381 interpreter process. This could cause failures in non-Distutils subprocesses
1382 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001383 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001384 deployment target only in the environment of each build subprocess. It is
1385 still possible to globally override the default by setting
1386 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1387 greater or equal to the default value, the value with which the interpreter
1388 was built.

1418 the ticker doesn't have to wind down to zero from the old starting point
1419 before the new interval takes effect. And if the user increases the
1420 interval, it makes sure the new limit takes effect right away rather have an
1421 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002372- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2373 This prevents user-created self-referencing ordered dictionaries from
2374 becoming permanently uncollectable GC garbage. The downside is that
2375 removing __del__ means that the internal doubly-linked list has to wait for
2376 GC collection rather than freeing memory immediately when the refcnt drops
2377 to zero.

2445 when the underlying raw IO channel was e.g. a socket. Report and original
2446 patch by Jason V. Miller.

2839 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

3221
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003222- Issue #7301: Add environment variable $PYTHONWARNINGS.
3223
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003224- Issue #8329: Don't return the same lists from select.select when no fds are
3225 changed.
3226
Georg Brandlfee0f442010-05-22 21:26:21 +00003227- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003228 on 64-bit machines. The shift count for either left or right shift is
3229 permitted to be up to sys.maxsize.
3230
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003231- Ensure that tokenization of identifiers is not affected by locale.

3236
Georg Brandlfee0f442010-05-22 21:26:21 +00003237- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3238 with a non-empty format string. This is an effort to future-proof user
3239 code. If a derived class does not currently implement __format__ but later
3240 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003241 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003242 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003243
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003244- Issue #8268: Old-style classes (not just instances) now support weak

3274
Georg Brandlfee0f442010-05-22 21:26:21 +00003275- Issue #8257: The Decimal construct now accepts a float instance directly,
3276 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003277

3279 Decimal('1.100000000000000088817841970012523233890533447265625')
3280
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003281- collections.Counter() now supports a subtract() method.
3282
Georg Brandlfee0f442010-05-22 21:26:21 +00003283- The functools module now has a total_ordering() class decorator to simplify
3284 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003292- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3293 InvalidOperation instead of returning False. (Comparisons involving a quiet
3294 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3295 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003296
Georg Brandlfee0f442010-05-22 21:26:21 +00003297- Issue #2531: Comparison operations between floats and Decimal instances now
3298 return a result based on the numeric values of the operands; previously they
3299 returned an arbitrary result based on the relative ordering of id(float) and
3300 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003301
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003302- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003303 argument `-` which tells it to read files to compile from stdin. Each line is
3304 read on demand and the named file is compiled immediately. (Original patch by
3305 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00003312 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003313
Georg Brandlfee0f442010-05-22 21:26:21 +00003314- Comparisons using one of <, <=, >, >= between a complex instance and a
3315 Fractions instance now raise TypeError instead of returning True/False. This
3316 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3317 <=> complex, and complex <=> complex comparisons.

3680 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3681 returning NULL. The macro now returns a statically allocated empty string
3682 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003735 file position when calling `truncate()`. It would previously change the file
3736 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003737 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3740 class used to represent files stored inside an archive. The new
3741 implementation is significantly faster and can be wrapped in a

3743 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3756 encoded string for them. This ensures that the upload and register commands
3757 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00003840- Issue #5080: A number of functions and methods previously produced a

3842 These functions and methods now raise TypeError instead. The majority of the
3843 effects of this change are in the extension modules, but some core functions
3844 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3845 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004028- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4029 decimal string that's guaranteed to round back to x under correct rounding
4030 (with round-half-to-even rounding mode). Previously it gave a string based on
4031 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4032 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4033 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004034
Georg Brandlba83f822010-03-14 09:50:54 +00004035- Issue #7117: On almost all platforms: float-to-string and string-to-float
4036 conversions within Python are now correctly rounded. Places these conversions
4037 occur include: str for floats and complex numbers; the float and complex
4038 constructors; old-style and new-style numeric formatting; serialization and
4039 deserialization of floats and complex numbers using marshal, pickle and json;
4040 parsing of float and imaginary literals in Python code; Decimal-to-float
4041 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004042
Georg Brandlba83f822010-03-14 09:50:54 +00004043 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4044 providing correctly-rounded strtod and dtoa C functions. This code is
4045 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4046 the C compiler. There may be a small number of platforms on which correct
4047 operation of this code cannot be guaranteed, so the code is not used: notably,
4048 this applies to platforms where the C double format is not IEEE 754 binary64,
4049 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4050 and Python's configure script is unable to determine how to change the FPU
4051 precision. On these platforms conversions use the platform strtod and dtoa,
4052 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004054- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4055 uses the correctly-rounded string <-> float conversions described above (when
4056 available), and so produces correctly rounded results that will display nicely
4057 under the float repr. There are two related small changes: (1) round now
4058 accepts any class with an ``__index__()`` method for its second argument (but
4059 no longer accepts floats for the second argument), and (2) an excessively
4060 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4061 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004438- On windows, ``os.chdir()`` given unicode was not working if
4439 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4440 this code path is really executed because I cannot move to such directory on
4441 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004443- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4444 element is temporarily replaced with an equivalent frozenset. But the
4445 eventual KeyError would always report the empty ``frozenset()`` as the missing

4467 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4468 step. This avoids problems with counting UTF-8 bytes that ignores the effect

5843
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005844- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5845 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5846 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5847 ``printf`` function, whereas PyString_FromFormat has an independent
5848 implementation and uses "%zd" on all platforms for size_t values.
5849 This makes a difference on win64, where ``printf`` needs "%Id" to display
5850 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005852- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5856 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00005869- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005870 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5871 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5872 when given a tuple of classes as second argument, were looking up
5873 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5874 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005945 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5946 for catch_warnings() also led to an improvement in the raising of a
5947 DeprecationWarning related to warnings.warn_explicit().
5948
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005949- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005972- Issue #2975: When compiling several extension modules with Visual Studio 2008
5973 from the same python interpreter, some environment variables would grow
5974 without limit.
5975
Benjamin Peterson37346b22008-08-23 20:27:43 +00005976- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006013What's New in Python 2.6 beta 3?
6014================================
6015
Barry Warsaw07a4a382008-08-21 01:15:08 +00006016*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006017
6018Core and Builtins
6019-----------------
6020
Guido van Rossumf8402962008-08-20 15:01:50 +00006021- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6022 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6023 extensions do not automatically benefit from the class attribute
6024 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6025 to their tp_flags field if they care. This is a backwards
6026 compatibility feature; in 3.0, all types will use the cache by
6027 default.
6028
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006029- Keyword arguments can now follow starred arguments. (``f(a, *args,
6030 keyword=23)`` is now valid syntax.)
6031
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006032- ctypes function pointers that are COM methods have a boolean True
6033 value again.
6034
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006035- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6036 by denying s# to parse objects that have a releasebuffer procedure,
6037 and introducing s*.
6038
Georg Brandl1e13ea92008-08-11 09:07:59 +00006039- Issue #3537: Fix an assertion failure when an empty but presized dict
6040 object was stored in the freelist.
6041
Mark Dickinsonb6467572008-08-04 21:30:09 +00006042- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6043 ValueError consistently across platforms.
6044
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006045- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6046 (64bit Unix, for example), unichr() would truncate its argument and return
6047 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6048
Neal Norwitze7d8be82008-07-31 17:17:14 +00006049- Apply security patches from Apple.
6050
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006051- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6052 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6053
Antoine Pitrou92f82162008-07-25 22:22:08 +00006054- Issue #1819: function calls with several named parameters are now on
6055 average 35% faster (as measured by pybench).
6056
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006057- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6058 the python debugger steps into a class statement: the free variables (local
6059 variables defined in an outer scope) would be deleted from the outer scope.
6060
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006061- Issue #2620: Overflow checking when allocating or reallocating memory
6062 was not always being done properly in some python types and extension
6063 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6064 all been updated to perform better checks and places in the code that
6065 would previously leak memory on the error path when such an allocation
6066 failed have been fixed.
6067

6069-------
6070
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006071- Issue #3612: Added some missing basic types in ctypes.wintypes.
6072
Benjamin Petersone977ad42008-08-20 01:42:01 +00006073- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6074 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6075
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006076- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6077 version reported by these tools does not necessarily follow the python
6078 version numbering scheme, so the module is less strict when parsing it.
6079
Nick Coghlanf70385a2008-08-18 12:42:46 +00006080- Issue #2235: Added Py3k warnings for types which will become unhashable
6081 under the stricter __hash__ inheritance rules in 3.0. Several types
6082 which did not meet the rules for hash invariants and were already
6083 unhashable in 3.0 have now been explicitly flagged as unhashable in
6084 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6085 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6086
Brett Cannon88f801d2008-08-18 00:46:22 +00006087- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6088 imported into the module but exposed as part of the module's API.
6089
Brett Cannon7b96f072008-08-18 00:41:11 +00006090- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6091
Brett Cannon46225e72008-08-18 00:36:52 +00006092- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006094- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6095
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006096- Issue #3575: Incremental decoder's decode function now takes bytearray
6097 by using 's*' instead of 't#'.
6098
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006099- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006100 fails unicode conversion on 2nd parameter. (windows only)
6101
Georg Brandl222e2082010-08-01 22:27:39 +00006102- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006103 in a redirect.
6104
Brett Cannonabe423e2008-08-16 21:47:07 +00006105- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006106 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006107
Facundo Batistaeb90b782008-08-16 14:44:07 +00006108- Issue #2776: fixed small issue when handling an URL with double slash
6109 after a 302 response in the case of not going through a proxy.
6110
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006111- Issue #2676: in the email package, content-type parsing was hanging on
6112 pathological input because of quadratic or exponential behaviour of a
6113 regular expression.
6114
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006115- Issue #3476: binary buffered reading through the new "io" library is now
6116 thread-safe.
6117
Brett Cannonbf3157b2008-08-14 05:00:03 +00006118- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6119 since mimetools itself is deprecated. Because modules are cached, all
6120 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6121
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006122- Issue #3134: shutil referenced undefined WindowsError symbol.
6123
Robert Schuppenies14646332008-08-10 11:01:53 +00006124- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6125 menu entries were not deleted.
6126
Brett Cannon83e81842008-08-09 23:30:55 +00006127- Copied the implementation of reduce() to _functools.reduce() to have a
6128 version that did not raise a DeprecationWarning under -3.
6129
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006130- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6131 a MemoryError rather than silently stop the iteration.
6132
Guido van Rossum59ce9012008-08-09 14:55:34 +00006133- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6134 to _sre.compile() will now be rejected. This should not affect anybody
6135 since the re.compile() function never generates invalid re-bytecode.
6136
Skip Montanaroa032bf42008-08-08 22:52:51 +00006137- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6138 upon first access it can be automatically initialized from the csv file if
6139 it wasn't initialized during instantiation.
6140
Brett Cannon3aa2a492008-08-06 22:28:09 +00006141- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6142 the reload() built-in has been removed.
6143
Brett Cannon7e30b672008-08-04 21:52:25 +00006144- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006145 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006156 asking for a specific length. This problem only affected files opened
6157 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006158

6183 file name rather than a ZipInfo instance, so files are extracted with
6184 mode 0600 rather than 000 under Unix.
6185
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006186- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6187 argument in python 2.5, this broke code that subclassed Popen to include its
6188 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6203 regarding lack of coverage of new-style classes have also been
6204 removed, since the coverage is now fairly reasonable.

6214
Georg Brandl3e483f62008-07-16 22:57:41 +00006215- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6216 its methods now allow for items objects that can be converted to
6217 an integer using operator.index().
6218
Mark Dickinson64b7e502008-07-16 09:40:03 +00006219- Issue #3360: Fix incorrect parsing of '020000000000.0', which

Mark Dickinson7103aa42008-07-15 19:08:33 +00006225- Issue #3008: the float type has a new instance method 'float.hex'
6226 and a new class method 'float.fromhex' to convert floating-point
6227 numbers to and from hexadecimal strings, respectively.
6228
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006229- Issue #2235: __hash__ is once again inherited by default. To allow
6230 collections.Hashable to remain meaningful in the presence of the
6231 default hash implementation (object.__hash__), it is now possible
6232 to explicit block inheritance of hash by setting __hash__=None at
6233 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6234 level.
6235
Nick Coghlanb028f502008-07-13 14:52:36 +00006236- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6237 the parent module cannot be found while performing an absolute import.
6238 This means that an incorrectly defined __package__ attribute will
6239 now only prevent relative imports in that module rather than causing
6240 all imports from that module to fail.
6241
Nick Coghlan14ff9942008-07-08 14:21:42 +00006242- Issue #2517: Allow unicode messages in Exceptions again by correctly

6253
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006254- Issue #3004: Minor change to slice.indices(): the start and stop
6255 arguments are now treated identically, making the behaviour easier
6256 to describe and understand. For example, slice(None, -10,
6257 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6258 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6259 10, -1).

6302 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006303 wrong because the actual transmitted size could differ from the

6780 not called by default for backwards-compatibility reasons. Setting
6781 ``warnings.showwarning()`` to an implementation that lacks support
6782 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006845- Issue #2550: The approach used by client/server code for obtaining
6846 ports to listen on in network-oriented tests has been refined in an
6847 effort to facilitate running multiple instances of the entire
6848 regression test suite in parallel without issue.
6849 test_support.bind_port() has been fixed such that it will always
6850 return a unique port -- which wasn't always the case with the
6851 previous implementation, especially if socket options had been set
6852 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6853 new implementation of bind_port() will actually raise an exception
6854 if it is passed an AF_INET/SOCK_STREAM socket with either the
6855 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6856 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6857 the socket it's been passed. This currently only applies to
6858 Windows. This option prevents any other sockets from binding to the
6859 host/port we've bound to, thus removing the possibility of the
6860 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6861 when a second SOCK_STREAM socket binds and accepts to a host/port
6862 that's already been bound by another socket. The optional preferred
6863 port parameter to bind_port() has been removed. Under no
6864 circumstances should tests be hard coding ports!
6865
6866 test_support.find_unused_port() has also been introduced, which will
6867 pass a temporary socket object to bind_port() in order to obtain an
6868 unused port. The temporary socket object is then closed and
6869 deleted, and the port is returned. This method should only be used
6870 for obtaining an unused port in order to pass to an external program
6871 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6872 a parameter to a server-oriented class that doesn't give you direct
6873 access to the underlying socket used.
6874
6875 Finally, test_support.HOST has been introduced, which should be used
6876 for the host argument of any relevant socket calls (i.e. bind and
6877 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006878
6879 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006880 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006881 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6882 test_asynchat and test_socket_ssl.
6883
Georg Brandl3ee81df2008-05-17 18:14:43 +00006884 It is now possible for multiple instances of the regression test
6885 suite to run in parallel without issue.

7052 values on 32-bit vs. 64-bit python interpreters. Both were correct,
7053 but they now both return a signed integer object for consistency.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007069 optional: it defaults to the traceback of the exception that is
7070 currently being handled (is mandatory to be in the middle of an
7071 exception, otherwise it raises ValueError).

Facundo Batistafc2d0102008-02-23 12:01:13 +00007163
Eric Smitha73fbe72008-02-23 03:09:44 +00007164- Added the future_builtins module, which contains hex() and oct().
7165 These are the PEP 3127 version of these functions, designed to be
7166 compatible with the hex() and oct() builtins from Python 3.0. They
7167 differ slightly in their output formats from the existing, unchanged
7168 Python 2.6 builtins. The expected usage of the future_builtins
7169 module is:
7170 from future_builtins import hex, oct
7171
Eric Smith7ef40bf2008-02-20 23:34:22 +00007172- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7173 exponents for exponents with absolute value < 100. Follows C99
7174 standard. This is a change on Windows, which would use 3 digits.
7175 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7176 so that any alterations it does to the resulting string will be
7177 available in stringlib/formatter.h (for float.__format__).
7178
Eric Smith5a3c1352008-02-19 13:21:56 +00007179- Implemented PEP 3101, Advanced String Formatting. This adds a new
7180 builtin format(); a format() method for str and unicode; a
7181 __format__() method to object, str, unicode, int, long, float, and
7182 datetime; the class string.Formatter; and the C API
7183 PyObject_Format().
7184
Georg Brandl3ee81df2008-05-17 18:14:43 +00007185- Fixed several potential crashes, all caused by specially crafted
7186 __del__ methods exploiting objects in temporarily inconsistent
7187 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007188
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007189- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007190 prevent a possible crash: an Abstract Base Class would try to access
7191 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007192
Georg Brandl3ee81df2008-05-17 18:14:43 +00007193- Fixed repr() and str() of complex numbers with infinity or nan as

Georg Brandl3ee81df2008-05-17 18:14:43 +00007196- Clear all free lists during a gc.collect() of the highest generation
7197 in order to allow pymalloc to free more arenas. Python may give back
7198 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007199
Georg Brandl3ee81df2008-05-17 18:14:43 +00007200- Issue #2045: Fix an infinite recursion triggered when printing a
7201 subclass of collections.defaultdict, if its default_factory is set
7202 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007203
Christian Heimesf75dbef2008-02-08 00:11:31 +00007204- Fixed a minor memory leak in dictobject.c. The content of the free
7205 list was not freed on interpreter shutdown.
7206
Georg Brandl21e99f42010-03-07 15:23:59 +00007207- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007208 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007209
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7211 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007212 to compact the internal free lists of pre-allocted ints and floats.
7213
Georg Brandl3ee81df2008-05-17 18:14:43 +00007214- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7215 calls. Python expected the return type int but the fork familie
7216 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007217
Georg Brandl3ee81df2008-05-17 18:14:43 +00007218- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7219 appear in the same code unit.

7228 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007229
Georg Brandl3ee81df2008-05-17 18:14:43 +00007230- Patch #1473257: generator objects gain a gi_code attribute. This is
7231 the same object as the func_code attribute of the function that
7232 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007233
Georg Brandl3ee81df2008-05-17 18:14:43 +00007234- Issue #1920: "while 0" statements were completely removed by the
7235 compiler, even in the presence of an "else" clause, which is
7236 supposed to be run when the condition is false. Now the compiler
7237 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007238
Guido van Rossumeead05f2008-01-24 18:21:02 +00007239- A few crashers fixed: weakref_in_del.py (issue #1377858);
7240 loosing_dict_ref.py (issue #1303614, test67.py);
7241 borrowed_ref_[34].py (not in tracker).
7242
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007243- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007244 suppressed while an extension is loaded by calling SetErrorMode in
7245 dynload_win.c. The error is still reported properly.
7246
Georg Brandl3ee81df2008-05-17 18:14:43 +00007247- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007248 several extension methods and modules do not work without unicode
7249 support.
7250
Georg Brandl26543b12008-01-21 18:36:51 +00007251- Issue #1882: when compiling code from a string, encoding cookies in the
7252 second line of code were not always recognized correctly.
7253
Georg Brandl14404b62008-01-19 19:27:05 +00007254- Issue #1679: "0x" was taken as a valid integer literal.
7255
Georg Brandl6caad7d2008-01-26 14:19:22 +00007256- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007257 added.
7258
Christian Heimesc94e2b52008-01-14 04:13:37 +00007259- sys.float_info / PyFloat_GetInfo: The floating point information
7260 object was converted from a dict to a specialized structseq object.
7261
Georg Brandl3ee81df2008-05-17 18:14:43 +00007262- Patch #1816: Added sys.flags structseq. It exposes the status of
7263 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007264
Georg Brandl3ee81df2008-05-17 18:14:43 +00007265- Objects/structseq.c: Implemented new structseq representation. The
7266 patch makes structseqs (e.g. the return value of os.stat) more
7267 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007268
Georg Brandl3ee81df2008-05-17 18:14:43 +00007269- Patch #1700288: added a type attribute cache that caches method
7270 accesses, resulting in speedups in heavily object-oriented code.

7278 envvar and sys.dont_write_bytecode attribute. All these can be set
7279 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007280
Georg Brandl3ee81df2008-05-17 18:14:43 +00007281- Improve some exception messages when Windows fails to load an
7282 extension module. Now we get for example '%1 is not a valid Win32
7283 application' instead of 'error code 193'.

7296 dictionary size. There is a new opcode, STORE_MAP, for adding
7297 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00007341- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007342 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7343 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007344
Georg Brandl3ee81df2008-05-17 18:14:43 +00007345- Issue #1686386: Tuple's tp_repr did not take into account the
7346 possibility of having a self-referential tuple, which is possible
7347 from C code. Nor did object's tp_str consider that a type's tp_str
7348 could do something that could lead to an inifinite recursion.
7349 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7350 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007352- Issue #1164: It was possible to trigger deadlock when using the
7353 'print' statement to write to a file since the GIL was not released
7354 as needed. Now PyObject_Print() does the right thing along with
7355 various tp_print implementations of the built-in types and those in
7356 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00007365- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007366 PyObject_Call() never calling back out to Python code to trigger
7367 recursion depth updates/checks. Required the creation of a static
7368 RuntimeError instance in case normalizing an exception put the
7369 recursion check value past its limit. Fixes crashers
7370 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007385- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007386 __*__ attributes. (Some already existed, e.g., __doc__ and
7387 __name__.)

7393 calls.
7394
Collin Winter62903052007-05-18 23:11:24 +00007395- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007396 "except E as target:". This is to provide forwards compatibility
7397 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007404- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007405 setting a plain string, ie don't expand to single letter identifiers.
7406
Raymond Hettinger13936692007-04-11 18:40:58 +00007407- Request #1191699: Slices can now be pickled.
7408
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007409- Request #1193128: str.translate() now allows a None argument for

7411 remaining characters.
7412
Georg Brandl5cb76c12007-03-21 09:00:39 +00007413- Patch #1682205: a TypeError while unpacking an iterable is no longer

7417
Guido van Rossum143b5642007-03-23 04:58:42 +00007418- Bug #1683368: The object.__init__() and object.__new__() methods are
7419 now stricter in rejecting excess arguments. The only time when
7420 either allows excess arguments is when it is not overridden and the
7421 other one is. For backwards compatibility, when both are
7422 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007423 warning later). Also, type.__init__() insists on the same signature
7424 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007425
Georg Brandl3ee81df2008-05-17 18:14:43 +00007426- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7427 object to complex using its __complex__() method before falling back
7428 to the __float__() method. Therefore, the functions in the cmath
7429 module now can operate on objects that define a __complex__()
7430 method.

7434 same slot names.

7441 its type.

7447
Georg Brandl7b9c5552007-03-12 14:30:05 +00007448- Bug #1678647: write a newline after printing an exception in any
7449 case, even when converting the value to a string failed.
7450
Georg Brandl871f1bc2007-03-12 13:17:36 +00007451- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007452 its argument, if it exists. If not, it will work like before. This
7453 allows customizing the output of dir() in the presence of a
7454 __getattr__().

7458
Georg Brandl3ee81df2008-05-17 18:14:43 +00007459- Patch #1675981: remove unreachable code from ``type.__new__()``

7463 parthensized forms. This means complex(repr(x)) now works instead of
7464 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007465
Georg Brandlaa2321b2007-03-07 00:40:28 +00007466- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007467 makes the filenames the warning module prints much more sensible
7468 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007481- Patch #1674228: when assigning a slice (old-style), check for the
7482 sq_ass_slice instead of the sq_slice slot.
7483
Georg Brandl3ee81df2008-05-17 18:14:43 +00007484- When printing an unraisable error, don't print exceptions. before
7485 the name. This duplicates the behavior whening normally printing
7486 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00007628- Removed uses of dict.has_key() from distutils, and uses of

8052
Georg Brandl92a6bae2007-03-13 17:43:32 +00008053- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008054 are set for invalid interpolation sequences that would lead to
8055 errors on reading back those values.

8111 TestCase and TestSuite subclasses (not instances) are no longer
8112 accepted in TestSuite.addTest(). This should cause no
8113 incompatibility since it never made sense with ordinary subclasses
8114 -- the failure just occurred later, with a more cumbersome
8115 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008402 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00008404 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008503- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008504 time so that opening a database previously created with the DB_DUP
8505 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8506 opens. Specifically: dictionary assignment to a DB object will
8507 replace all values for a given key when the database allows
8508 duplicate values. DB users should use DB.put(k, v) when they want
8509 to store duplicates; not DB[k] = v.

8518 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008788- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008789 periodic threadstate and signal checking in tight loops. By
8790 default, this option is turned-off. It should only be enabled in
8791 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00008848
Georg Brandl3ee81df2008-05-17 18:14:43 +00008849- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8850 to ``PyTuple_SetItem``, it can be used to populate a brand new

8863
Georg Brandl3ee81df2008-05-17 18:14:43 +00008864- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8865 of w# format code incorrectly truncated the length to an int, even
8866 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8867 incorrect results with huge strings.

8895 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008896
Georg Brandl3ee81df2008-05-17 18:14:43 +00008897- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8898 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008899

Georg Brandl3ee81df2008-05-17 18:14:43 +00008925- Removed the macfs module. It had been deprecated since Python 2.5.
8926 This lead to the deprecation of macostools.touched() as it relied
