1079
1080- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1081 and later systems as is currently done for Python 3.x installers.
1082 For 2.7.7 only, we will provide three installers:
1083 the legacy deprecated 10.3+ 32-bit-only format;
1084 the newer 10.5+ 32-bit-only format;
1085 and the unchanged 10.6+ 64-/32-bit format.
1086 Although binary installers will no longer be available from
1087 python.org as of 2.7.8, it will still be possible to build from
1088 source on 10.3.9 and 10.4 systems if necessary.
1089 See Mac/BuildScript/README.txt for more information.

2470 In particular, fix extension module build failures when trying to use
2471 32-bit-only installer Pythons on systems with Xcode 4 (currently
2472 OS X 10.8, 10.7, and optionally 10.6).
2473 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2474 * Since Xcode 4 removes ppc support, extension module builds now
2475 check for ppc compiler support and by default remove ppc and
2476 ppc64 archs when they are not available.
2477 * Extension module builds now revert to using system installed
2478 headers and libs (/usr and /System/Library) if the SDK used
2479 to build the interpreter is not installed or has moved.
2480 * Try to avoid building extension modules with deprecated
2481 and problematic Apple llvm-gcc compiler. If original compiler
2482 is not available, use clang instead by default.

2850 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01002926- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2927 Distutils-based packages with C extension modules may fail because
2928 Apple has removed gcc-4.2, the version used to build python.org
2929 64-bit/32-bit Pythons. If the user does not explicitly override
2930 the default C compiler by setting the CC environment variable,
2931 Distutils will now attempt to compile extension modules with clang
2932 if gcc-4.2 is required but not found. Also as a convenience, if
2933 the user does explicitly set CC, substitute its value as the default
2934 compiler in the Distutils LDSHARED configuration variable for OS X.
2935 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2936 SDK, neither of which are available in Xcode 4. This change does not
2937 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003187- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3188 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3189 interpreter process. This could cause failures in non-Distutils subprocesses
3190 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003191 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003192 deployment target only in the environment of each build subprocess. It is
3193 still possible to globally override the default by setting
3194 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3195 greater or equal to the default value, the value with which the interpreter
3196 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04003224- sys.setcheckinterval() now updates the current ticker count as well as
3225 updating the check interval, so if the user decreases the check interval,
3226 the ticker doesn't have to wind down to zero from the old starting point
3227 before the new interval takes effect. And if the user increases the
3228 interval, it makes sure the new limit takes effect right away rather have an
3229 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00004226- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4227 This prevents user-created self-referencing ordered dictionaries from
4228 becoming permanently uncollectable GC garbage. The downside is that
4229 removing __del__ means that the internal doubly-linked list has to wait for
4230 GC collection rather than freeing memory immediately when the refcnt drops
4231 to zero.
4232

4299 when the underlying raw IO channel was e.g. a socket. Report and original
4300 patch by Jason V. Miller.

4692 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4693 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

4902 operation raises multiple signals and more than one of those signals is
4903 trapped, the specification determines the order in which the signals should be

5074
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00005075- Issue #7301: Add environment variable $PYTHONWARNINGS.
5076
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00005077- Issue #8329: Don't return the same lists from select.select when no fds are
5078 changed.
5079
Georg Brandlfee0f442010-05-22 21:26:21 +00005080- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005081 on 64-bit machines. The shift count for either left or right shift is
5082 permitted to be up to sys.maxsize.
5083
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00005084- Ensure that tokenization of identifiers is not affected by locale.

5089
Georg Brandlfee0f442010-05-22 21:26:21 +00005090- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5091 with a non-empty format string. This is an effort to future-proof user
5092 code. If a derived class does not currently implement __format__ but later
5093 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005094 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005095 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00005096

Georg Brandlfee0f442010-05-22 21:26:21 +00005128- Issue #8257: The Decimal construct now accepts a float instance directly,
5129 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005130

5133
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005134- collections.Counter() now supports a subtract() method.
5135
Georg Brandlfee0f442010-05-22 21:26:21 +00005136- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00005145- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5146 InvalidOperation instead of returning False. (Comparisons involving a quiet
5147 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5148 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005149
Georg Brandlfee0f442010-05-22 21:26:21 +00005150- Issue #2531: Comparison operations between floats and Decimal instances now
5151 return a result based on the numeric values of the operands; previously they
5152 returned an arbitrary result based on the relative ordering of id(float) and
5153 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005154
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005155- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005156 argument `-` which tells it to read files to compile from stdin. Each line is
5157 read on demand and the named file is compiled immediately. (Original patch by
5158 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00005163- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5164 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005165 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005166
Georg Brandlfee0f442010-05-22 21:26:21 +00005167- Comparisons using one of <, <=, >, >= between a complex instance and a
5168 Fractions instance now raise TypeError instead of returning True/False. This
5169 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5170 <=> complex, and complex <=> complex comparisons.

5275 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00005277 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5278 inconsistent: __int__ was used for some integer codes but not for others, and
5279 the set of integer codes for which it was used differed between native packing
5280 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005588 file position when calling `truncate()`. It would previously change the file
5589 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005590 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

5593 class used to represent files stored inside an archive. The new
5594 implementation is significantly faster and can be wrapped in a

5596 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5609 encoded string for them. This ensures that the upload and register commands
5610 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00005693- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005694 DeprecationWarning when passed a float argument where an integer was expected.
5695 These functions and methods now raise TypeError instead. The majority of the
5696 effects of this change are in the extension modules, but some core functions
5697 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5698 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00005880- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5881 decimal string that's guaranteed to round back to x under correct rounding
5882 (with round-half-to-even rounding mode). Previously it gave a string based on
5883 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5884 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5885 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005886
Georg Brandlba83f822010-03-14 09:50:54 +00005887- Issue #7117: On almost all platforms: float-to-string and string-to-float
5888 conversions within Python are now correctly rounded. Places these conversions
5889 occur include: str for floats and complex numbers; the float and complex
5890 constructors; old-style and new-style numeric formatting; serialization and
5891 deserialization of floats and complex numbers using marshal, pickle and json;
5892 parsing of float and imaginary literals in Python code; Decimal-to-float
5893 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005894
Georg Brandlba83f822010-03-14 09:50:54 +00005895 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5896 providing correctly-rounded strtod and dtoa C functions. This code is
5897 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5898 the C compiler. There may be a small number of platforms on which correct
5899 operation of this code cannot be guaranteed, so the code is not used: notably,
5900 this applies to platforms where the C double format is not IEEE 754 binary64,
5901 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5902 and Python's configure script is unable to determine how to change the FPU
5903 precision. On these platforms conversions use the platform strtod and dtoa,
5904 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005906- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5907 uses the correctly-rounded string <-> float conversions described above (when
5908 available), and so produces correctly rounded results that will display nicely
5909 under the float repr. There are two related small changes: (1) round now
5910 accepts any class with an ``__index__()`` method for its second argument (but
5911 no longer accepts floats for the second argument), and (2) an excessively
5912 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5913 raises an exception.

6063 of 12. Previously, the behavior the same but with a default precision of 6.
6064 This more closely matches ``str()``, and reduces surprises when adding

6292 this code path is really executed because I cannot move to such directory on
6293 win2k)

6319 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

7722 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Brett Cannon1eaf0742008-09-02 01:25:16 +00007821 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7822 for catch_warnings() also led to an improvement in the raising of a
7823 DeprecationWarning related to warnings.warn_explicit().
7824
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007825- The deprecation warnings for the old camelCase threading API were removed.

7847
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007848- Issue #2975: When compiling several extension modules with Visual Studio 2008
7849 from the same python interpreter, some environment variables would grow
7850 without limit.
7851
Benjamin Peterson37346b22008-08-23 20:27:43 +00007852- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
7853 exploitation of poor argument checking.
7854
Gerhard Häringef2276b2008-09-12 13:54:06 +00007855- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007889What's New in Python 2.6 beta 3?
7890================================
7891
Barry Warsaw07a4a382008-08-21 01:15:08 +00007892*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007893
7894Core and Builtins
7895-----------------
7896
Guido van Rossumf8402962008-08-20 15:01:50 +00007897- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7898 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7899 extensions do not automatically benefit from the class attribute
7900 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7901 to their tp_flags field if they care. This is a backwards
7902 compatibility feature; in 3.0, all types will use the cache by
7903 default.
7904
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007905- Keyword arguments can now follow starred arguments. (``f(a, *args,
7906 keyword=23)`` is now valid syntax.)
7907
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007908- ctypes function pointers that are COM methods have a boolean True
7909 value again.
7910
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007911- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7912 by denying s# to parse objects that have a releasebuffer procedure,
7913 and introducing s*.
7914
Georg Brandl1e13ea92008-08-11 09:07:59 +00007915- Issue #3537: Fix an assertion failure when an empty but presized dict
7916 object was stored in the freelist.
7917
Mark Dickinsonb6467572008-08-04 21:30:09 +00007918- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7919 ValueError consistently across platforms.
7920
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007921- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7922 (64bit Unix, for example), unichr() would truncate its argument and return
7923 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7924
Neal Norwitze7d8be82008-07-31 17:17:14 +00007925- Apply security patches from Apple.
7926
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007927- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7928 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7929
Antoine Pitrou92f82162008-07-25 22:22:08 +00007930- Issue #1819: function calls with several named parameters are now on
7931 average 35% faster (as measured by pybench).
7932
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007933- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7934 the python debugger steps into a class statement: the free variables (local
7935 variables defined in an outer scope) would be deleted from the outer scope.
7936
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007937- Issue #2620: Overflow checking when allocating or reallocating memory
7938 was not always being done properly in some python types and extension
7939 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7940 all been updated to perform better checks and places in the code that
7941 would previously leak memory on the error path when such an allocation
7942 failed have been fixed.
7943
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007944Library
7945-------
7946
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007947- Issue #3612: Added some missing basic types in ctypes.wintypes.
7948
Benjamin Petersone977ad42008-08-20 01:42:01 +00007949- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7950 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7951
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007952- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7953 version reported by these tools does not necessarily follow the python
7954 version numbering scheme, so the module is less strict when parsing it.
7955
Nick Coghlanf70385a2008-08-18 12:42:46 +00007956- Issue #2235: Added Py3k warnings for types which will become unhashable
7957 under the stricter __hash__ inheritance rules in 3.0. Several types
7958 which did not meet the rules for hash invariants and were already
7959 unhashable in 3.0 have now been explicitly flagged as unhashable in
7960 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7961 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7962
Brett Cannon88f801d2008-08-18 00:46:22 +00007963- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7964 imported into the module but exposed as part of the module's API.
7965
Brett Cannon7b96f072008-08-18 00:41:11 +00007966- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7967
Brett Cannon46225e72008-08-18 00:36:52 +00007968- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007970- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7971
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007972- Issue #3575: Incremental decoder's decode function now takes bytearray
7973 by using 's*' instead of 't#'.
7974
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007975- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007976 fails unicode conversion on 2nd parameter. (windows only)
7977
Georg Brandl222e2082010-08-01 22:27:39 +00007978- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007979 in a redirect.
7980
Brett Cannonabe423e2008-08-16 21:47:07 +00007981- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007982 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007983
Facundo Batistaeb90b782008-08-16 14:44:07 +00007984- Issue #2776: fixed small issue when handling an URL with double slash
7985 after a 302 response in the case of not going through a proxy.
7986
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007987- Issue #2676: in the email package, content-type parsing was hanging on
7988 pathological input because of quadratic or exponential behaviour of a
7989 regular expression.
7990
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007991- Issue #3476: binary buffered reading through the new "io" library is now
7992 thread-safe.
7993
Brett Cannonbf3157b2008-08-14 05:00:03 +00007994- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7995 since mimetools itself is deprecated. Because modules are cached, all
7996 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7997
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007998- Issue #3134: shutil referenced undefined WindowsError symbol.
7999
Robert Schuppenies14646332008-08-10 11:01:53 +00008000- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8001 menu entries were not deleted.
8002
Brett Cannon83e81842008-08-09 23:30:55 +00008003- Copied the implementation of reduce() to _functools.reduce() to have a
8004 version that did not raise a DeprecationWarning under -3.
8005
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008006- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8007 a MemoryError rather than silently stop the iteration.
8008
Guido van Rossum59ce9012008-08-09 14:55:34 +00008009- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8010 to _sre.compile() will now be rejected. This should not affect anybody
8011 since the re.compile() function never generates invalid re-bytecode.
8012
Skip Montanaroa032bf42008-08-08 22:52:51 +00008013- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8014 upon first access it can be automatically initialized from the csv file if
8015 it wasn't initialized during instantiation.
8016
Brett Cannon3aa2a492008-08-06 22:28:09 +00008017- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8018 the reload() built-in has been removed.
8019
Brett Cannon7e30b672008-08-04 21:52:25 +00008020- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008021 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00008032 asking for a specific length. This problem only affected files opened
8033 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00008034

8079 regarding lack of coverage of new-style classes have also been
8080 removed, since the coverage is now fairly reasonable.

8089-----------------
8090
Georg Brandl3e483f62008-07-16 22:57:41 +00008091- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8092 its methods now allow for items objects that can be converted to
8093 an integer using operator.index().
8094
Mark Dickinson64b7e502008-07-16 09:40:03 +00008095- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8096 produced a ValueError instead of giving the correct float.
8097
Eric Smitha5fa5a22008-07-16 00:11:49 +00008098- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8099 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8100
Mark Dickinson7103aa42008-07-15 19:08:33 +00008101- Issue #3008: the float type has a new instance method 'float.hex'
8102 and a new class method 'float.fromhex' to convert floating-point
8103 numbers to and from hexadecimal strings, respectively.
8104
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008105- Issue #2235: __hash__ is once again inherited by default. To allow
8106 collections.Hashable to remain meaningful in the presence of the
8107 default hash implementation (object.__hash__), it is now possible
8108 to explicit block inheritance of hash by setting __hash__=None at
8109 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8110 level.
8111
Nick Coghlanb028f502008-07-13 14:52:36 +00008112- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8113 the parent module cannot be found while performing an absolute import.
8114 This means that an incorrectly defined __package__ attribute will
8115 now only prevent relative imports in that module rather than causing
8116 all imports from that module to fail.
8117
Nick Coghlan14ff9942008-07-08 14:21:42 +00008118- Issue #2517: Allow unicode messages in Exceptions again by correctly
8119 bypassing the instance dictionary when looking up __unicode__ on
8120 new-style classes.
8121
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008122- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8123 set to a custom object whose write() method happens to install
8124 another file in sys.stdout.
8125
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008126- Issue #3088: Corrected a race condition in classes derived from
8127 threading.local: the first member set by a thread could be saved in
8128 another thread's dictionary.
8129
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008130- Issue #3004: Minor change to slice.indices(): the start and stop
8131 arguments are now treated identically, making the behaviour easier
8132 to describe and understand. For example, slice(None, -10,
8133 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8134 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8135 10, -1).
8136
Georg Brandl278fc502008-07-19 12:46:12 +00008137- Issue #3219: Calling a function with repeated keyword arguments,
8138 f(a=2, a=23), would not cause a syntax error. This was a regression
8139 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008140
Georg Brandl278fc502008-07-19 12:46:12 +00008141- Issue #2862: Make int and float freelist management consistent with
8142 other freelists. Changes their CompactFreeList apis into
8143 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00008144

8146-------
8147
Thomas Heller57adf222008-08-14 19:10:48 +00008148- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
8149 api functions without holding the GIL, which could lead to a fatal
8150 error when they failed.
8151
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008152- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
8153

Jesse Noller13e9d582008-07-16 14:32:36 +00008160- Issue #3125: Remove copy_reg in multiprocessing and replace it with
8161 ForkingPickler.register() to resolve conflict with ctypes.
8162
Vinay Sajip51e65192008-07-18 09:01:10 +00008163- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00008164
Thomas Heller880f5292008-07-15 19:39:38 +00008165- Issue #3313: Fixed a crash when a failed dlopen() call does not set
8166 a valid dlerror() message.
8167
Thomas Heller2bad6572008-07-15 17:19:50 +00008168- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8169 incomplete structure was created.
8170
Brett Cannon3d0b9f02008-07-13 01:15:07 +00008171- Issue #3339: dummy_thread.acquire() should not return None.
8172

8174
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008175- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008176
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008177- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8178 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008179 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008180 content-length. The problem had been corrected in the 2.4 branch, but never
8181 merged into trunk.
8182
Georg Brandle78fbcc2008-07-05 10:13:36 +00008183- Issue #2663: add filtering capability to shutil.copytree().

8187- Issue #1526: Allow more than 64k files to be added to Zip64 file.
8188
8189- Issue #1746: Correct handling of zipfile archive comments (previously
8190 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00008191 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00008192
Vinay Sajip51e65192008-07-18 09:01:10 +00008193- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008194 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00008195
Nick Coghlanc060b0e2008-07-02 13:09:19 +00008196- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
8197 handling is now the same as that of other special attributes like __name__).
8198
Brett Cannon8bb8fa52008-07-02 01:57:08 +00008199- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
8200 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008648- Issue #1631171: Re-implement the 'warnings' module in C (the
8649 original Python code has been kept as backup). This will allow for
8650 using the 'warning's machinery in such places as the parser where
8651 use of pure Python code is not possible. Both the ``showarning()``
8652 and ``formatwarning()`` gain an optional 'line' argument which is
8653 not called by default for backwards-compatibility reasons. Setting
8654 ``warnings.showwarning()`` to an implementation that lacks support
8655 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008718- Issue #2550: The approach used by client/server code for obtaining
8719 ports to listen on in network-oriented tests has been refined in an
8720 effort to facilitate running multiple instances of the entire
8721 regression test suite in parallel without issue.
8722 test_support.bind_port() has been fixed such that it will always
8723 return a unique port -- which wasn't always the case with the
8724 previous implementation, especially if socket options had been set
8725 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8726 new implementation of bind_port() will actually raise an exception
8727 if it is passed an AF_INET/SOCK_STREAM socket with either the
8728 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8729 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8730 the socket it's been passed. This currently only applies to
8731 Windows. This option prevents any other sockets from binding to the
8732 host/port we've bound to, thus removing the possibility of the
8733 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8734 when a second SOCK_STREAM socket binds and accepts to a host/port
8735 that's already been bound by another socket. The optional preferred
8736 port parameter to bind_port() has been removed. Under no
8737 circumstances should tests be hard coding ports!
8738
8739 test_support.find_unused_port() has also been introduced, which will
8740 pass a temporary socket object to bind_port() in order to obtain an
8741 unused port. The temporary socket object is then closed and
8742 deleted, and the port is returned. This method should only be used
8743 for obtaining an unused port in order to pass to an external program
8744 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8745 a parameter to a server-oriented class that doesn't give you direct
8746 access to the underlying socket used.
8747
8748 Finally, test_support.HOST has been introduced, which should be used
8749 for the host argument of any relevant socket calls (i.e. bind and
8750 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008751
8752 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008753 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008754 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8755 test_asynchat and test_socket_ssl.
8756
Georg Brandl3ee81df2008-05-17 18:14:43 +00008757 It is now possible for multiple instances of the regression test
8758 suite to run in parallel without issue.

8914 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00008915 platform.machine() and platform.processor() will report this
8916 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00009037- Added the future_builtins module, which contains hex() and oct().
9038 These are the PEP 3127 version of these functions, designed to be
9039 compatible with the hex() and oct() builtins from Python 3.0. They
9040 differ slightly in their output formats from the existing, unchanged
9041 Python 2.6 builtins. The expected usage of the future_builtins
9042 module is:
9043 from future_builtins import hex, oct
9044
Eric Smith7ef40bf2008-02-20 23:34:22 +00009045- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9046 exponents for exponents with absolute value < 100. Follows C99
9047 standard. This is a change on Windows, which would use 3 digits.
9048 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9049 so that any alterations it does to the resulting string will be
9050 available in stringlib/formatter.h (for float.__format__).
9051
Eric Smith5a3c1352008-02-19 13:21:56 +00009052- Implemented PEP 3101, Advanced String Formatting. This adds a new
9053 builtin format(); a format() method for str and unicode; a
9054 __format__() method to object, str, unicode, int, long, float, and
9055 datetime; the class string.Formatter; and the C API
9056 PyObject_Format().
9057
Georg Brandl3ee81df2008-05-17 18:14:43 +00009058- Fixed several potential crashes, all caused by specially crafted
9059 __del__ methods exploiting objects in temporarily inconsistent
9060 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009061
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009062- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009063 prevent a possible crash: an Abstract Base Class would try to access
9064 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00009065

Georg Brandl3ee81df2008-05-17 18:14:43 +00009069- Clear all free lists during a gc.collect() of the highest generation
9070 in order to allow pymalloc to free more arenas. Python may give back
9071 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009072
Georg Brandl3ee81df2008-05-17 18:14:43 +00009073- Issue #2045: Fix an infinite recursion triggered when printing a
9074 subclass of collections.defaultdict, if its default_factory is set
9075 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009076
Christian Heimesf75dbef2008-02-08 00:11:31 +00009077- Fixed a minor memory leak in dictobject.c. The content of the free
9078 list was not freed on interpreter shutdown.
9079
Georg Brandl21e99f42010-03-07 15:23:59 +00009080- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00009081 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00009082
Georg Brandl3ee81df2008-05-17 18:14:43 +00009083- Patch #1953: Added ``sys._compact_freelists()`` and the C API
9084 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009085 to compact the internal free lists of pre-allocted ints and floats.
9086
Georg Brandl3ee81df2008-05-17 18:14:43 +00009087- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9088 calls. Python expected the return type int but the fork familie
9089 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009090
Georg Brandl3ee81df2008-05-17 18:14:43 +00009091- Issue #1678380: Fix a bug that identifies 0j and -0j when they

9101 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00009102
Georg Brandl3ee81df2008-05-17 18:14:43 +00009103- Patch #1473257: generator objects gain a gi_code attribute. This is
9104 the same object as the func_code attribute of the function that
9105 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009106
Georg Brandl3ee81df2008-05-17 18:14:43 +00009107- Issue #1920: "while 0" statements were completely removed by the
9108 compiler, even in the presence of an "else" clause, which is
9109 supposed to be run when the condition is false. Now the compiler
9110 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009111
Guido van Rossumeead05f2008-01-24 18:21:02 +00009112- A few crashers fixed: weakref_in_del.py (issue #1377858);
9113 loosing_dict_ref.py (issue #1303614, test67.py);
9114 borrowed_ref_[34].py (not in tracker).
9115
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009116- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009117 suppressed while an extension is loaded by calling SetErrorMode in
9118 dynload_win.c. The error is still reported properly.
9119
Georg Brandl3ee81df2008-05-17 18:14:43 +00009120- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009121 several extension methods and modules do not work without unicode
9122 support.
9123
Georg Brandl26543b12008-01-21 18:36:51 +00009124- Issue #1882: when compiling code from a string, encoding cookies in the
9125 second line of code were not always recognized correctly.
9126
Georg Brandl14404b62008-01-19 19:27:05 +00009127- Issue #1679: "0x" was taken as a valid integer literal.
9128
Georg Brandl6caad7d2008-01-26 14:19:22 +00009129- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009130 added.
9131
Christian Heimesc94e2b52008-01-14 04:13:37 +00009132- sys.float_info / PyFloat_GetInfo: The floating point information
9133 object was converted from a dict to a specialized structseq object.
9134
Georg Brandl3ee81df2008-05-17 18:14:43 +00009135- Patch #1816: Added sys.flags structseq. It exposes the status of
9136 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009137
Georg Brandl3ee81df2008-05-17 18:14:43 +00009138- Objects/structseq.c: Implemented new structseq representation. The
9139 patch makes structseqs (e.g. the return value of os.stat) more
9140 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009141
Georg Brandl3ee81df2008-05-17 18:14:43 +00009142- Patch #1700288: added a type attribute cache that caches method

9151 envvar and sys.dont_write_bytecode attribute. All these can be set
9152 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009153
Georg Brandl3ee81df2008-05-17 18:14:43 +00009154- Improve some exception messages when Windows fails to load an
9155 extension module. Now we get for example '%1 is not a valid Win32

9169 dictionary size. There is a new opcode, STORE_MAP, for adding
9170 entries to the dictionary.

9213
Georg Brandl21e99f42010-03-07 15:23:59 +00009214- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009215 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9216 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009217
Georg Brandl3ee81df2008-05-17 18:14:43 +00009218- Issue #1686386: Tuple's tp_repr did not take into account the
9219 possibility of having a self-referential tuple, which is possible
9220 from C code. Nor did object's tp_str consider that a type's tp_str
9221 could do something that could lead to an inifinite recursion.
9222 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9223 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009224
Georg Brandl3ee81df2008-05-17 18:14:43 +00009225- Issue #1164: It was possible to trigger deadlock when using the
9226 'print' statement to write to a file since the GIL was not released
9227 as needed. Now PyObject_Print() does the right thing along with
9228 various tp_print implementations of the built-in types and those in
9229 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00009238- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009239 PyObject_Call() never calling back out to Python code to trigger
9240 recursion depth updates/checks. Required the creation of a static
9241 RuntimeError instance in case normalizing an exception put the
9242 recursion check value past its limit. Fixes crashers
9243 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009259 __*__ attributes. (Some already existed, e.g., __doc__ and
9260 __name__.)

9266 calls.
9267
Collin Winter62903052007-05-18 23:11:24 +00009268- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009269 "except E as target:". This is to provide forwards compatibility
9270 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009277- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009278 setting a plain string, ie don't expand to single letter identifiers.
9279
Raymond Hettinger13936692007-04-11 18:40:58 +00009280- Request #1191699: Slices can now be pickled.
9281
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009282- Request #1193128: str.translate() now allows a None argument for
9283 translations that only remove characters without re-mapping the
9284 remaining characters.
9285
Georg Brandl5cb76c12007-03-21 09:00:39 +00009286- Patch #1682205: a TypeError while unpacking an iterable is no longer

9290
Guido van Rossum143b5642007-03-23 04:58:42 +00009291- Bug #1683368: The object.__init__() and object.__new__() methods are
9292 now stricter in rejecting excess arguments. The only time when
9293 either allows excess arguments is when it is not overridden and the
9294 other one is. For backwards compatibility, when both are
9295 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009296 warning later). Also, type.__init__() insists on the same signature
9297 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009298
Georg Brandl3ee81df2008-05-17 18:14:43 +00009299- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9300 object to complex using its __complex__() method before falling back
9301 to the __float__() method. Therefore, the functions in the cmath
9302 module now can operate on objects that define a __complex__()
9303 method.

9314 its type.

9320
Georg Brandl7b9c5552007-03-12 14:30:05 +00009321- Bug #1678647: write a newline after printing an exception in any
9322 case, even when converting the value to a string failed.
9323
Georg Brandl871f1bc2007-03-12 13:17:36 +00009324- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009325 its argument, if it exists. If not, it will work like before. This
9326 allows customizing the output of dir() in the presence of a
9327 __getattr__().

9337 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009338
Georg Brandlaa2321b2007-03-07 00:40:28 +00009339- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009340 makes the filenames the warning module prints much more sensible
9341 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00009354- Patch #1674228: when assigning a slice (old-style), check for the
9355 sq_ass_slice instead of the sq_slice slot.
9356
Georg Brandl3ee81df2008-05-17 18:14:43 +00009357- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00009926 are set for invalid interpolation sequences that would lead to

Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010268 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +000010270 does not claim to support starttls. Adds the

10353 silently miscode subclasses of those types. Now, it raises a
10354 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010369- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000010370 time so that opening a database previously created with the DB_DUP
10371 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10372 opens. Specifically: dictionary assignment to a DB object will
10373 replace all values for a given key when the database allows
10374 duplicate values. DB users should use DB.put(k, v) when they want
10375 to store duplicates; not DB[k] = v.

10736 of w# format code incorrectly truncated the length to an int, even
10737 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10738 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010768- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10769 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
