1540 In particular, fix extension module build failures when trying to use
1541 32-bit-only installer Pythons on systems with Xcode 4 (currently
1542 OS X 10.8, 10.7, and optionally 10.6).
1543 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1544 * Since Xcode 4 removes ppc support, extension module builds now
1545 check for ppc compiler support and by default remove ppc and
1546 ppc64 archs when they are not available.
1547 * Extension module builds now revert to using system installed
1548 headers and libs (/usr and /System/Library) if the SDK used
1549 to build the interpreter is not installed or has moved.
1550 * Try to avoid building extension modules with deprecated
1551 and problematic Apple llvm-gcc compiler. If original compiler
1552 is not available, use clang instead by default.

1984 Distutils-based packages with C extension modules may fail because
1985 Apple has removed gcc-4.2, the version used to build python.org
1986 64-bit/32-bit Pythons. If the user does not explicitly override
1987 the default C compiler by setting the CC environment variable,
1988 Distutils will now attempt to compile extension modules with clang
1989 if gcc-4.2 is required but not found. Also as a convenience, if
1990 the user does explicitly set CC, substitute its value as the default
1991 compiler in the Distutils LDSHARED configuration variable for OS X.
1992 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1993 SDK, neither of which are available in Xcode 4. This change does not
1994 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002244- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2245 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2246 interpreter process. This could cause failures in non-Distutils subprocesses
2247 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002248 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002249 deployment target only in the environment of each build subprocess. It is
2250 still possible to globally override the default by setting
2251 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2252 greater or equal to the default value, the value with which the interpreter
2253 was built.

2283 the ticker doesn't have to wind down to zero from the old starting point
2284 before the new interval takes effect. And if the user increases the
2285 interval, it makes sure the new limit takes effect right away rather have an
2286 early task switch before recognizing the new interval.

3267 This prevents user-created self-referencing ordered dictionaries from
3268 becoming permanently uncollectable GC garbage. The downside is that
3269 removing __del__ means that the internal doubly-linked list has to wait for
3270 GC collection rather than freeing memory immediately when the refcnt drops
3271 to zero.

3731 of the number of bytes specified by the start byte.
3732 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3733 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3745 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

3942 operation raises multiple signals and more than one of those signals is
3943 trapped, the specification determines the order in which the signals should be

4114
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004115- Issue #7301: Add environment variable $PYTHONWARNINGS.
4116
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004117- Issue #8329: Don't return the same lists from select.select when no fds are
4118 changed.
4119
Georg Brandlfee0f442010-05-22 21:26:21 +00004120- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004121 on 64-bit machines. The shift count for either left or right shift is
4122 permitted to be up to sys.maxsize.
4123
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004124- Ensure that tokenization of identifiers is not affected by locale.

4129
Georg Brandlfee0f442010-05-22 21:26:21 +00004130- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4131 with a non-empty format string. This is an effort to future-proof user
4132 code. If a derived class does not currently implement __format__ but later
4133 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004134 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004135 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004136

Georg Brandlfee0f442010-05-22 21:26:21 +00004168- Issue #8257: The Decimal construct now accepts a float instance directly,
4169 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004170
4171 >>> Decimal(1.1)
4172 Decimal('1.100000000000000088817841970012523233890533447265625')
4173
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004174- collections.Counter() now supports a subtract() method.
4175
Georg Brandlfee0f442010-05-22 21:26:21 +00004176- The functools module now has a total_ordering() class decorator to simplify
4177 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004185- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4186 InvalidOperation instead of returning False. (Comparisons involving a quiet
4187 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4188 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004189
Georg Brandlfee0f442010-05-22 21:26:21 +00004190- Issue #2531: Comparison operations between floats and Decimal instances now
4191 return a result based on the numeric values of the operands; previously they
4192 returned an arbitrary result based on the relative ordering of id(float) and
4193 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004194
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004195- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004196 argument `-` which tells it to read files to compile from stdin. Each line is
4197 read on demand and the named file is compiled immediately. (Original patch by
4198 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00004203- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4204 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004205 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004206
Georg Brandlfee0f442010-05-22 21:26:21 +00004207- Comparisons using one of <, <=, >, >= between a complex instance and a
4208 Fractions instance now raise TypeError instead of returning True/False. This
4209 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4210 <=> complex, and complex <=> complex comparisons.

4319 the set of integer codes for which it was used differed between native packing
4320 and standard packing.)

4573 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4574 returning NULL. The macro now returns a statically allocated empty string
4575 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004628 file position when calling `truncate()`. It would previously change the file
4629 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004630 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4633 class used to represent files stored inside an archive. The new
4634 implementation is significantly faster and can be wrapped in a
4635 ``io.BufferedReader`` object for more speedups. It also solves an issue
4636 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004647- Issue #7748: Since unicode values are supported for some metadata options in
4648 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4649 encoded string for them. This ensures that the upload and register commands
4650 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00004733- Issue #5080: A number of functions and methods previously produced a

4735 These functions and methods now raise TypeError instead. The majority of the
4736 effects of this change are in the extension modules, but some core functions
4737 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4738 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004920- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4921 decimal string that's guaranteed to round back to x under correct rounding
4922 (with round-half-to-even rounding mode). Previously it gave a string based on
4923 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4924 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4925 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004926
Georg Brandlba83f822010-03-14 09:50:54 +00004927- Issue #7117: On almost all platforms: float-to-string and string-to-float
4928 conversions within Python are now correctly rounded. Places these conversions
4929 occur include: str for floats and complex numbers; the float and complex
4930 constructors; old-style and new-style numeric formatting; serialization and
4931 deserialization of floats and complex numbers using marshal, pickle and json;
4932 parsing of float and imaginary literals in Python code; Decimal-to-float
4933 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004934
Georg Brandlba83f822010-03-14 09:50:54 +00004935 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4936 providing correctly-rounded strtod and dtoa C functions. This code is
4937 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4938 the C compiler. There may be a small number of platforms on which correct
4939 operation of this code cannot be guaranteed, so the code is not used: notably,
4940 this applies to platforms where the C double format is not IEEE 754 binary64,
4941 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4942 and Python's configure script is unable to determine how to change the FPU
4943 precision. On these platforms conversions use the platform strtod and dtoa,
4944 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004946- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4947 uses the correctly-rounded string <-> float conversions described above (when
4948 available), and so produces correctly rounded results that will display nicely
4949 under the float repr. There are two related small changes: (1) round now
4950 accepts any class with an ``__index__()`` method for its second argument (but
4951 no longer accepts floats for the second argument), and (2) an excessively
4952 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4953 raises an exception.

5103 of 12. Previously, the behavior the same but with a default precision of 6.

5332 this code path is really executed because I cannot move to such directory on
5333 win2k)

5359 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006739- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6740 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6741 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6742 ``printf`` function, whereas PyString_FromFormat has an independent
6743 implementation and uses "%zd" on all platforms for size_t values.
6744 This makes a difference on win64, where ``printf`` needs "%Id" to display
6745 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00006765 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Brett Cannon1eaf0742008-09-02 01:25:16 +00006840 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6841 for catch_warnings() also led to an improvement in the raising of a
6842 DeprecationWarning related to warnings.warn_explicit().
6843
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006844- The deprecation warnings for the old camelCase threading API were removed.

6866
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006867- Issue #2975: When compiling several extension modules with Visual Studio 2008
6868 from the same python interpreter, some environment variables would grow
6869 without limit.
6870
Benjamin Peterson37346b22008-08-23 20:27:43 +00006871- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6872 exploitation of poor argument checking.
6873
Gerhard Häringef2276b2008-09-12 13:54:06 +00006874- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
6875
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00006876- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
6877 remaining ones have "pysqlite_" prefix.
6878
Gerhard Häringe6872eb2008-09-12 22:33:22 +00006879- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

6887 wrapper for warnings.catch_warnings() that makes it easier to check
6888 that expected warning messages are being reported.
6889

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006908What's New in Python 2.6 beta 3?
6909================================
6910
Barry Warsaw07a4a382008-08-21 01:15:08 +00006911*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006912
6913Core and Builtins
6914-----------------
6915
Guido van Rossumf8402962008-08-20 15:01:50 +00006916- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6917 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6918 extensions do not automatically benefit from the class attribute
6919 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6920 to their tp_flags field if they care. This is a backwards
6921 compatibility feature; in 3.0, all types will use the cache by
6922 default.
6923
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006924- Keyword arguments can now follow starred arguments. (``f(a, *args,
6925 keyword=23)`` is now valid syntax.)
6926
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006927- ctypes function pointers that are COM methods have a boolean True
6928 value again.
6929
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006930- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6931 by denying s# to parse objects that have a releasebuffer procedure,
6932 and introducing s*.
6933
Georg Brandl1e13ea92008-08-11 09:07:59 +00006934- Issue #3537: Fix an assertion failure when an empty but presized dict
6935 object was stored in the freelist.
6936
Mark Dickinsonb6467572008-08-04 21:30:09 +00006937- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6938 ValueError consistently across platforms.
6939
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006940- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6941 (64bit Unix, for example), unichr() would truncate its argument and return
6942 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6943
Neal Norwitze7d8be82008-07-31 17:17:14 +00006944- Apply security patches from Apple.
6945
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006946- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6947 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6948
Antoine Pitrou92f82162008-07-25 22:22:08 +00006949- Issue #1819: function calls with several named parameters are now on
6950 average 35% faster (as measured by pybench).
6951
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006952- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6953 the python debugger steps into a class statement: the free variables (local
6954 variables defined in an outer scope) would be deleted from the outer scope.
6955
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006956- Issue #2620: Overflow checking when allocating or reallocating memory
6957 was not always being done properly in some python types and extension
6958 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6959 all been updated to perform better checks and places in the code that
6960 would previously leak memory on the error path when such an allocation
6961 failed have been fixed.
6962
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006963Library
6964-------
6965
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006966- Issue #3612: Added some missing basic types in ctypes.wintypes.
6967
Benjamin Petersone977ad42008-08-20 01:42:01 +00006968- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6969 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6970
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006971- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6972 version reported by these tools does not necessarily follow the python
6973 version numbering scheme, so the module is less strict when parsing it.
6974
Nick Coghlanf70385a2008-08-18 12:42:46 +00006975- Issue #2235: Added Py3k warnings for types which will become unhashable
6976 under the stricter __hash__ inheritance rules in 3.0. Several types
6977 which did not meet the rules for hash invariants and were already
6978 unhashable in 3.0 have now been explicitly flagged as unhashable in
6979 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6980 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6981
Brett Cannon88f801d2008-08-18 00:46:22 +00006982- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6983 imported into the module but exposed as part of the module's API.
6984
Brett Cannon7b96f072008-08-18 00:41:11 +00006985- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6986
Brett Cannon46225e72008-08-18 00:36:52 +00006987- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006989- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6990
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006991- Issue #3575: Incremental decoder's decode function now takes bytearray
6992 by using 's*' instead of 't#'.
6993
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006994- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006995 fails unicode conversion on 2nd parameter. (windows only)
6996
Georg Brandl222e2082010-08-01 22:27:39 +00006997- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006998 in a redirect.
6999
Brett Cannonabe423e2008-08-16 21:47:07 +00007000- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007001 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007002
Facundo Batistaeb90b782008-08-16 14:44:07 +00007003- Issue #2776: fixed small issue when handling an URL with double slash
7004 after a 302 response in the case of not going through a proxy.
7005
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007006- Issue #2676: in the email package, content-type parsing was hanging on
7007 pathological input because of quadratic or exponential behaviour of a
7008 regular expression.
7009
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007010- Issue #3476: binary buffered reading through the new "io" library is now
7011 thread-safe.
7012
Brett Cannonbf3157b2008-08-14 05:00:03 +00007013- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7014 since mimetools itself is deprecated. Because modules are cached, all
7015 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7016
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007017- Issue #3134: shutil referenced undefined WindowsError symbol.
7018
Robert Schuppenies14646332008-08-10 11:01:53 +00007019- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7020 menu entries were not deleted.
7021
Brett Cannon83e81842008-08-09 23:30:55 +00007022- Copied the implementation of reduce() to _functools.reduce() to have a
7023 version that did not raise a DeprecationWarning under -3.
7024
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007025- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7026 a MemoryError rather than silently stop the iteration.
7027
Guido van Rossum59ce9012008-08-09 14:55:34 +00007028- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7029 to _sre.compile() will now be rejected. This should not affect anybody
7030 since the re.compile() function never generates invalid re-bytecode.
7031
Skip Montanaroa032bf42008-08-08 22:52:51 +00007032- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7033 upon first access it can be automatically initialized from the csv file if
7034 it wasn't initialized during instantiation.
7035
Brett Cannon3aa2a492008-08-06 22:28:09 +00007036- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7037 the reload() built-in has been removed.
7038
Brett Cannon7e30b672008-08-04 21:52:25 +00007039- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007040 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007051 asking for a specific length. This problem only affected files opened
7052 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007053

7078 file name rather than a ZipInfo instance, so files are extracted with
7079 mode 0600 rather than 000 under Unix.
7080
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007081- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7082 argument in python 2.5, this broke code that subclassed Popen to include its
7083 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7098 regarding lack of coverage of new-style classes have also been
7099 removed, since the coverage is now fairly reasonable.

7109
Georg Brandl3e483f62008-07-16 22:57:41 +00007110- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7111 its methods now allow for items objects that can be converted to
7112 an integer using operator.index().
7113
Mark Dickinson64b7e502008-07-16 09:40:03 +00007114- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7115 produced a ValueError instead of giving the correct float.
7116
Eric Smitha5fa5a22008-07-16 00:11:49 +00007117- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Nick Coghlan6d6bd442008-07-15 15:40:22 +00007124- Issue #2235: __hash__ is once again inherited by default. To allow
7125 collections.Hashable to remain meaningful in the presence of the
7126 default hash implementation (object.__hash__), it is now possible
7127 to explicit block inheritance of hash by setting __hash__=None at
7128 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7129 level.
7130
Nick Coghlanb028f502008-07-13 14:52:36 +00007131- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7132 the parent module cannot be found while performing an absolute import.
7133 This means that an incorrectly defined __package__ attribute will
7134 now only prevent relative imports in that module rather than causing
7135 all imports from that module to fail.
7136
Nick Coghlan14ff9942008-07-08 14:21:42 +00007137- Issue #2517: Allow unicode messages in Exceptions again by correctly

7148
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007149- Issue #3004: Minor change to slice.indices(): the start and stop
7150 arguments are now treated identically, making the behaviour easier
7151 to describe and understand. For example, slice(None, -10,
7152 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7153 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7154 10, -1).

7197 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007198 wrong because the actual transmitted size could differ from the

7605 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007606 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007607
7608 This is controlled by the configure argument ``--with-universal-archs``:
7609
7610 - ``--with-universal-archs=all``: install 4-way universal
7611
7612 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7613
7614 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7615
7616 This option should be used in combination with ``--enable-universalsdk=``.
7617
7618 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7654 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007655
Christian Heimese74c8f22008-04-19 02:23:57 +00007656- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7657

Gregory P. Smith671c5d92008-04-09 18:18:43 +00007666
Georg Brandl3ee81df2008-05-17 18:14:43 +00007667- Issue #1631171: Re-implement the 'warnings' module in C (the
7668 original Python code has been kept as backup). This will allow for
7669 using the 'warning's machinery in such places as the parser where
7670 use of pure Python code is not possible. Both the ``showarning()``
7671 and ``formatwarning()`` gain an optional 'line' argument which is
7672 not called by default for backwards-compatibility reasons. Setting
7673 ``warnings.showwarning()`` to an implementation that lacks support
7674 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007737- Issue #2550: The approach used by client/server code for obtaining
7738 ports to listen on in network-oriented tests has been refined in an
7739 effort to facilitate running multiple instances of the entire
7740 regression test suite in parallel without issue.
7741 test_support.bind_port() has been fixed such that it will always
7742 return a unique port -- which wasn't always the case with the
7743 previous implementation, especially if socket options had been set
7744 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7745 new implementation of bind_port() will actually raise an exception
7746 if it is passed an AF_INET/SOCK_STREAM socket with either the
7747 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7748 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7749 the socket it's been passed. This currently only applies to
7750 Windows. This option prevents any other sockets from binding to the
7751 host/port we've bound to, thus removing the possibility of the
7752 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7753 when a second SOCK_STREAM socket binds and accepts to a host/port
7754 that's already been bound by another socket. The optional preferred
7755 port parameter to bind_port() has been removed. Under no
7756 circumstances should tests be hard coding ports!
7757
7758 test_support.find_unused_port() has also been introduced, which will
7759 pass a temporary socket object to bind_port() in order to obtain an
7760 unused port. The temporary socket object is then closed and
7761 deleted, and the port is returned. This method should only be used
7762 for obtaining an unused port in order to pass to an external program
7763 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7764 a parameter to a server-oriented class that doesn't give you direct
7765 access to the underlying socket used.
7766
7767 Finally, test_support.HOST has been introduced, which should be used
7768 for the host argument of any relevant socket calls (i.e. bind and
7769 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007770
7771 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007772 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007773 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7774 test_asynchat and test_socket_ssl.
7775
Georg Brandl3ee81df2008-05-17 18:14:43 +00007776 It is now possible for multiple instances of the regression test
7777 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008056- Added the future_builtins module, which contains hex() and oct().
8057 These are the PEP 3127 version of these functions, designed to be
8058 compatible with the hex() and oct() builtins from Python 3.0. They
8059 differ slightly in their output formats from the existing, unchanged
8060 Python 2.6 builtins. The expected usage of the future_builtins
8061 module is:
8062 from future_builtins import hex, oct
8063
Eric Smith7ef40bf2008-02-20 23:34:22 +00008064- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8065 exponents for exponents with absolute value < 100. Follows C99
8066 standard. This is a change on Windows, which would use 3 digits.
8067 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8068 so that any alterations it does to the resulting string will be
8069 available in stringlib/formatter.h (for float.__format__).
8070
Eric Smith5a3c1352008-02-19 13:21:56 +00008071- Implemented PEP 3101, Advanced String Formatting. This adds a new
8072 builtin format(); a format() method for str and unicode; a
8073 __format__() method to object, str, unicode, int, long, float, and
8074 datetime; the class string.Formatter; and the C API
8075 PyObject_Format().
8076
Georg Brandl3ee81df2008-05-17 18:14:43 +00008077- Fixed several potential crashes, all caused by specially crafted
8078 __del__ methods exploiting objects in temporarily inconsistent
8079 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008080
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008081- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008082 prevent a possible crash: an Abstract Base Class would try to access
8083 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008084
Georg Brandl3ee81df2008-05-17 18:14:43 +00008085- Fixed repr() and str() of complex numbers with infinity or nan as

Georg Brandl3ee81df2008-05-17 18:14:43 +00008088- Clear all free lists during a gc.collect() of the highest generation
8089 in order to allow pymalloc to free more arenas. Python may give back
8090 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008091
Georg Brandl3ee81df2008-05-17 18:14:43 +00008092- Issue #2045: Fix an infinite recursion triggered when printing a
8093 subclass of collections.defaultdict, if its default_factory is set
8094 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008095
Christian Heimesf75dbef2008-02-08 00:11:31 +00008096- Fixed a minor memory leak in dictobject.c. The content of the free
8097 list was not freed on interpreter shutdown.
8098
Georg Brandl21e99f42010-03-07 15:23:59 +00008099- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008100 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008101
Georg Brandl3ee81df2008-05-17 18:14:43 +00008102- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8103 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008104 to compact the internal free lists of pre-allocted ints and floats.
8105
Georg Brandl3ee81df2008-05-17 18:14:43 +00008106- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8107 calls. Python expected the return type int but the fork familie
8108 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008109
Georg Brandl3ee81df2008-05-17 18:14:43 +00008110- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008122- Patch #1473257: generator objects gain a gi_code attribute. This is
8123 the same object as the func_code attribute of the function that
8124 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008125
Georg Brandl3ee81df2008-05-17 18:14:43 +00008126- Issue #1920: "while 0" statements were completely removed by the
8127 compiler, even in the presence of an "else" clause, which is
8128 supposed to be run when the condition is false. Now the compiler
8129 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008130
Guido van Rossumeead05f2008-01-24 18:21:02 +00008131- A few crashers fixed: weakref_in_del.py (issue #1377858);
8132 loosing_dict_ref.py (issue #1303614, test67.py);
8133 borrowed_ref_[34].py (not in tracker).
8134
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008135- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008136 suppressed while an extension is loaded by calling SetErrorMode in

8138
Georg Brandl3ee81df2008-05-17 18:14:43 +00008139- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008140 several extension methods and modules do not work without unicode
8141 support.
8142
Georg Brandl26543b12008-01-21 18:36:51 +00008143- Issue #1882: when compiling code from a string, encoding cookies in the
8144 second line of code were not always recognized correctly.
8145
Georg Brandl14404b62008-01-19 19:27:05 +00008146- Issue #1679: "0x" was taken as a valid integer literal.
8147
Georg Brandl6caad7d2008-01-26 14:19:22 +00008148- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008149 added.
8150
Christian Heimesc94e2b52008-01-14 04:13:37 +00008151- sys.float_info / PyFloat_GetInfo: The floating point information
8152 object was converted from a dict to a specialized structseq object.
8153
Georg Brandl3ee81df2008-05-17 18:14:43 +00008154- Patch #1816: Added sys.flags structseq. It exposes the status of
8155 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008156
Georg Brandl3ee81df2008-05-17 18:14:43 +00008157- Objects/structseq.c: Implemented new structseq representation. The
8158 patch makes structseqs (e.g. the return value of os.stat) more
8159 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008160
Georg Brandl3ee81df2008-05-17 18:14:43 +00008161- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00008186- Compiler now generates simpler and faster code for dictionary
8187 literals. The oparg for BUILD_MAP now indicates an estimated
8188 dictionary size. There is a new opcode, STORE_MAP, for adding
8189 entries to the dictionary.

8219 file can now be directly executed by passing their name to the
8220 interpreter. The directory/zipfile is automatically inserted as the
8221 first entry in sys.path.

8232
Georg Brandl21e99f42010-03-07 15:23:59 +00008233- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008234 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8235 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008236
Georg Brandl3ee81df2008-05-17 18:14:43 +00008237- Issue #1686386: Tuple's tp_repr did not take into account the
8238 possibility of having a self-referential tuple, which is possible
8239 from C code. Nor did object's tp_str consider that a type's tp_str
8240 could do something that could lead to an inifinite recursion.
8241 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8242 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008243
Georg Brandl3ee81df2008-05-17 18:14:43 +00008244- Issue #1164: It was possible to trigger deadlock when using the
8245 'print' statement to write to a file since the GIL was not released
8246 as needed. Now PyObject_Print() does the right thing along with
8247 various tp_print implementations of the built-in types and those in
8248 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008249
Georg Brandl3ee81df2008-05-17 18:14:43 +00008250- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00008257- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008258 PyObject_Call() never calling back out to Python code to trigger
8259 recursion depth updates/checks. Required the creation of a static
8260 RuntimeError instance in case normalizing an exception put the
8261 recursion check value past its limit. Fixes crashers
8262 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008277- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008278 __*__ attributes. (Some already existed, e.g., __doc__ and
8279 __name__.)

8285 calls.
8286
Collin Winter62903052007-05-18 23:11:24 +00008287- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008288 "except E as target:". This is to provide forwards compatibility
8289 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008296- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008297 setting a plain string, ie don't expand to single letter identifiers.
8298
Raymond Hettinger13936692007-04-11 18:40:58 +00008299- Request #1191699: Slices can now be pickled.
8300
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008301- Request #1193128: str.translate() now allows a None argument for
8302 translations that only remove characters without re-mapping the
8303 remaining characters.
8304
Georg Brandl5cb76c12007-03-21 09:00:39 +00008305- Patch #1682205: a TypeError while unpacking an iterable is no longer

8309
Guido van Rossum143b5642007-03-23 04:58:42 +00008310- Bug #1683368: The object.__init__() and object.__new__() methods are
8311 now stricter in rejecting excess arguments. The only time when
8312 either allows excess arguments is when it is not overridden and the
8313 other one is. For backwards compatibility, when both are
8314 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008315 warning later). Also, type.__init__() insists on the same signature
8316 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008317
Georg Brandl3ee81df2008-05-17 18:14:43 +00008318- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8319 object to complex using its __complex__() method before falling back
8320 to the __float__() method. Therefore, the functions in the cmath
8321 module now can operate on objects that define a __complex__()
8322 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008324- Patch #1623563: allow __class__ assignment for classes with
8325 __slots__. The old and the new class are still required to have the
8326 same slot names.

8333 its type.

8339
Georg Brandl7b9c5552007-03-12 14:30:05 +00008340- Bug #1678647: write a newline after printing an exception in any
8341 case, even when converting the value to a string failed.
8342
Georg Brandl871f1bc2007-03-12 13:17:36 +00008343- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008344 its argument, if it exists. If not, it will work like before. This
8345 allows customizing the output of dir() in the presence of a
8346 __getattr__().

8350
Georg Brandl3ee81df2008-05-17 18:14:43 +00008351- Patch #1675981: remove unreachable code from ``type.__new__()``

8355 parthensized forms. This means complex(repr(x)) now works instead of
8356 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008357
Georg Brandlaa2321b2007-03-07 00:40:28 +00008358- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008359 makes the filenames the warning module prints much more sensible
8360 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008373- Patch #1674228: when assigning a slice (old-style), check for the
8374 sq_ass_slice instead of the sq_slice slot.
8375
Georg Brandl3ee81df2008-05-17 18:14:43 +00008376- When printing an unraisable error, don't print exceptions. before
8377 the name. This duplicates the behavior whening normally printing
8378 exceptions.

Georg Brandl4e933132006-09-06 20:05:58 +00008461- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

8943
Georg Brandl92a6bae2007-03-13 17:43:32 +00008944- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008945 are set for invalid interpolation sequences that would lead to
8946 errors on reading back those values.

9002 TestCase and TestSuite subclasses (not instances) are no longer
9003 accepted in TestSuite.addTest(). This should cause no
9004 incompatibility since it never made sense with ordinary subclasses
9005 -- the failure just occurred later, with a more cumbersome
9006 exception.

9284 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009285
Georg Brandl3ee81df2008-05-17 18:14:43 +00009286- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009287 that the SMTP.starttls() caller no longer needs to call ehlo()
9288 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009289 does not claim to support starttls. Adds the
9290 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9371 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9372 silently miscode subclasses of those types. Now, it raises a
9373 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009374

Georg Brandl3ee81df2008-05-17 18:14:43 +00009389 time so that opening a database previously created with the DB_DUP
9390 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9391 opens. Specifically: dictionary assignment to a DB object will
9392 replace all values for a given key when the database allows
9393 duplicate values. DB users should use DB.put(k, v) when they want
9394 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009395

9755 of w# format code incorrectly truncated the length to an int, even
9756 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9757 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009758

Georg Brandl3ee81df2008-05-17 18:14:43 +00009787- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9788 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009813- Removed the macfs module. It had been deprecated since Python 2.5.
9814 This lead to the deprecation of macostools.touched() as it relied
9815 solely on macfs and was a no-op under OS X.
