Ned Deily0d0ea482012-02-10 12:59:06 +0100828- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
829 Distutils-based packages with C extension modules may fail because
830 Apple has removed gcc-4.2, the version used to build python.org
831 64-bit/32-bit Pythons. If the user does not explicitly override
832 the default C compiler by setting the CC environment variable,
833 Distutils will now attempt to compile extension modules with clang
834 if gcc-4.2 is required but not found. Also as a convenience, if
835 the user does explicitly set CC, substitute its value as the default
836 compiler in the Distutils LDSHARED configuration variable for OS X.
837 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
838 SDK, neither of which are available in Xcode 4. This change does not
839 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001112- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1113 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1114 interpreter process. This could cause failures in non-Distutils subprocesses
1115 and was unreliable since tests or user programs could modify the interpreter
1116 environment after Distutils set it. Instead, have Distutils set the the
1117 deployment target only in the environment of each build subprocess. It is
1118 still possible to globally override the default by setting
1119 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1120 greater or equal to the default value, the value with which the interpreter
1121 was built.

1151 the ticker doesn't have to wind down to zero from the old starting point
1152 before the new interval takes effect. And if the user increases the
1153 interval, it makes sure the new limit takes effect right away rather have an
1154 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002105- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2106 This prevents user-created self-referencing ordered dictionaries from
2107 becoming permanently uncollectable GC garbage. The downside is that
2108 removing __del__ means that the internal doubly-linked list has to wait for
2109 GC collection rather than freeing memory immediately when the refcnt drops
2110 to zero.
2111

R. David Murray7c4bf552010-08-25 01:45:57 +00002141- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2142 character years even if the message contains RFC822 two character years.

2178 when the underlying raw IO channel was e.g. a socket. Report and original
2179 patch by Jason V. Miller.

2954
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002955- Issue #7301: Add environment variable $PYTHONWARNINGS.
2956
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002957- Issue #8329: Don't return the same lists from select.select when no fds are
2958 changed.
2959
Georg Brandlfee0f442010-05-22 21:26:21 +00002960- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002961 on 64-bit machines. The shift count for either left or right shift is
2962 permitted to be up to sys.maxsize.
2963
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002964- Ensure that tokenization of identifiers is not affected by locale.

2969
Georg Brandlfee0f442010-05-22 21:26:21 +00002970- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2971 with a non-empty format string. This is an effort to future-proof user
2972 code. If a derived class does not currently implement __format__ but later
2973 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002974 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002975 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003008- Issue #8257: The Decimal construct now accepts a float instance directly,
3009 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003010

3013
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003014- collections.Counter() now supports a subtract() method.
3015
Georg Brandlfee0f442010-05-22 21:26:21 +00003016- The functools module now has a total_ordering() class decorator to simplify
3017 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003025- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3026 InvalidOperation instead of returning False. (Comparisons involving a quiet
3027 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3028 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003029
Georg Brandlfee0f442010-05-22 21:26:21 +00003030- Issue #2531: Comparison operations between floats and Decimal instances now
3031 return a result based on the numeric values of the operands; previously they
3032 returned an arbitrary result based on the relative ordering of id(float) and
3033 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003034
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003035- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003036 argument `-` which tells it to read files to compile from stdin. Each line is
3037 read on demand and the named file is compiled immediately. (Original patch by
3038 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00003043- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3044 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003045 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003046
Georg Brandlfee0f442010-05-22 21:26:21 +00003047- Comparisons using one of <, <=, >, >= between a complex instance and a
3048 Fractions instance now raise TypeError instead of returning True/False. This
3049 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3050 <=> complex, and complex <=> complex comparisons.

3159 the set of integer codes for which it was used differed between native packing
3160 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003468 file position when calling `truncate()`. It would previously change the file
3469 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003470 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3473 class used to represent files stored inside an archive. The new
3474 implementation is significantly faster and can be wrapped in a

3476 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003487- Issue #7748: Since unicode values are supported for some metadata options in
3488 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3489 encoded string for them. This ensures that the upload and register commands
3490 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00003573- Issue #5080: A number of functions and methods previously produced a

3575 These functions and methods now raise TypeError instead. The majority of the
3576 effects of this change are in the extension modules, but some core functions
3577 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3578 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00003761- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3762 decimal string that's guaranteed to round back to x under correct rounding
3763 (with round-half-to-even rounding mode). Previously it gave a string based on
3764 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3765 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3766 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003767
Georg Brandlba83f822010-03-14 09:50:54 +00003768- Issue #7117: On almost all platforms: float-to-string and string-to-float
3769 conversions within Python are now correctly rounded. Places these conversions
3770 occur include: str for floats and complex numbers; the float and complex
3771 constructors; old-style and new-style numeric formatting; serialization and
3772 deserialization of floats and complex numbers using marshal, pickle and json;
3773 parsing of float and imaginary literals in Python code; Decimal-to-float
3774 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003775
Georg Brandlba83f822010-03-14 09:50:54 +00003776 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3777 providing correctly-rounded strtod and dtoa C functions. This code is
3778 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3779 the C compiler. There may be a small number of platforms on which correct
3780 operation of this code cannot be guaranteed, so the code is not used: notably,
3781 this applies to platforms where the C double format is not IEEE 754 binary64,
3782 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3783 and Python's configure script is unable to determine how to change the FPU
3784 precision. On these platforms conversions use the platform strtod and dtoa,
3785 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003787- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3788 uses the correctly-rounded string <-> float conversions described above (when
3789 available), and so produces correctly rounded results that will display nicely
3790 under the float repr. There are two related small changes: (1) round now
3791 accepts any class with an ``__index__()`` method for its second argument (but
3792 no longer accepts floats for the second argument), and (2) an excessively
3793 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3794 raises an exception.

3944 of 12. Previously, the behavior the same but with a default precision of 6.

Georg Brandlba83f822010-03-14 09:50:54 +00004171- On windows, ``os.chdir()`` given unicode was not working if
4172 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4173 this code path is really executed because I cannot move to such directory on
4174 win2k)

4200 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

5576
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005577- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5578 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5579 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5580 ``printf`` function, whereas PyString_FromFormat has an independent
5581 implementation and uses "%zd" on all platforms for size_t values.
5582 This makes a difference on win64, where ``printf`` needs "%Id" to display
5583 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00005603 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

5606 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5607 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005678 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5679 for catch_warnings() also led to an improvement in the raising of a
5680 DeprecationWarning related to warnings.warn_explicit().
5681
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005682- The deprecation warnings for the old camelCase threading API were removed.

5704
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005705- Issue #2975: When compiling several extension modules with Visual Studio 2008
5706 from the same python interpreter, some environment variables would grow
5707 without limit.
5708
Benjamin Peterson37346b22008-08-23 20:27:43 +00005709- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5710 exploitation of poor argument checking.
5711
Gerhard Häringef2276b2008-09-12 13:54:06 +00005712- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
5713
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00005714- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
5715 remaining ones have "pysqlite_" prefix.
5716
Gerhard Häringe6872eb2008-09-12 22:33:22 +00005717- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

5725 wrapper for warnings.catch_warnings() that makes it easier to check
5726 that expected warning messages are being reported.
5727

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005746What's New in Python 2.6 beta 3?
5747================================
5748
Barry Warsaw07a4a382008-08-21 01:15:08 +00005749*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005750
5751Core and Builtins
5752-----------------
5753
Guido van Rossumf8402962008-08-20 15:01:50 +00005754- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5755 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5756 extensions do not automatically benefit from the class attribute
5757 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5758 to their tp_flags field if they care. This is a backwards
5759 compatibility feature; in 3.0, all types will use the cache by
5760 default.
5761
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005762- Keyword arguments can now follow starred arguments. (``f(a, *args,
5763 keyword=23)`` is now valid syntax.)
5764
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005765- ctypes function pointers that are COM methods have a boolean True
5766 value again.
5767
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005768- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5769 by denying s# to parse objects that have a releasebuffer procedure,
5770 and introducing s*.
5771
Georg Brandl1e13ea92008-08-11 09:07:59 +00005772- Issue #3537: Fix an assertion failure when an empty but presized dict
5773 object was stored in the freelist.
5774
Mark Dickinsonb6467572008-08-04 21:30:09 +00005775- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5776 ValueError consistently across platforms.
5777
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005778- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5779 (64bit Unix, for example), unichr() would truncate its argument and return
5780 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5781
Neal Norwitze7d8be82008-07-31 17:17:14 +00005782- Apply security patches from Apple.
5783
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005784- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5785 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5786
Antoine Pitrou92f82162008-07-25 22:22:08 +00005787- Issue #1819: function calls with several named parameters are now on
5788 average 35% faster (as measured by pybench).
5789
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005790- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5791 the python debugger steps into a class statement: the free variables (local
5792 variables defined in an outer scope) would be deleted from the outer scope.
5793
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005794- Issue #2620: Overflow checking when allocating or reallocating memory
5795 was not always being done properly in some python types and extension
5796 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5797 all been updated to perform better checks and places in the code that
5798 would previously leak memory on the error path when such an allocation
5799 failed have been fixed.

5802-------
5803

5805
Benjamin Petersone977ad42008-08-20 01:42:01 +00005806- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5807 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5808
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005809- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5810 version reported by these tools does not necessarily follow the python
5811 version numbering scheme, so the module is less strict when parsing it.
5812
Nick Coghlanf70385a2008-08-18 12:42:46 +00005813- Issue #2235: Added Py3k warnings for types which will become unhashable
5814 under the stricter __hash__ inheritance rules in 3.0. Several types
5815 which did not meet the rules for hash invariants and were already
5816 unhashable in 3.0 have now been explicitly flagged as unhashable in
5817 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5818 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5819
Brett Cannon88f801d2008-08-18 00:46:22 +00005820- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005827- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5828
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005829- Issue #3575: Incremental decoder's decode function now takes bytearray
5830 by using 's*' instead of 't#'.
5831
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005832- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005833 fails unicode conversion on 2nd parameter. (windows only)
5834
Georg Brandl222e2082010-08-01 22:27:39 +00005835- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005836 in a redirect.
5837
Brett Cannonabe423e2008-08-16 21:47:07 +00005838- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005839 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005840
Facundo Batistaeb90b782008-08-16 14:44:07 +00005841- Issue #2776: fixed small issue when handling an URL with double slash
5842 after a 302 response in the case of not going through a proxy.
5843
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005844- Issue #2676: in the email package, content-type parsing was hanging on
5845 pathological input because of quadratic or exponential behaviour of a
5846 regular expression.
5847
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005848- Issue #3476: binary buffered reading through the new "io" library is now
5849 thread-safe.
5850
Brett Cannonbf3157b2008-08-14 05:00:03 +00005851- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5852 since mimetools itself is deprecated. Because modules are cached, all
5853 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5854
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005855- Issue #3134: shutil referenced undefined WindowsError symbol.
5856
Robert Schuppenies14646332008-08-10 11:01:53 +00005857- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5858 menu entries were not deleted.
5859
Brett Cannon83e81842008-08-09 23:30:55 +00005860- Copied the implementation of reduce() to _functools.reduce() to have a
5861 version that did not raise a DeprecationWarning under -3.
5862
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005863- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5864 a MemoryError rather than silently stop the iteration.
5865
Guido van Rossum59ce9012008-08-09 14:55:34 +00005866- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5867 to _sre.compile() will now be rejected. This should not affect anybody
5868 since the re.compile() function never generates invalid re-bytecode.
5869
Skip Montanaroa032bf42008-08-08 22:52:51 +00005870- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5871 upon first access it can be automatically initialized from the csv file if
5872 it wasn't initialized during instantiation.
5873
Brett Cannon3aa2a492008-08-06 22:28:09 +00005874- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5875 the reload() built-in has been removed.
5876
Brett Cannon7e30b672008-08-04 21:52:25 +00005877- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005878 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005889 asking for a specific length. This problem only affected files opened
5890 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005891

5916 file name rather than a ZipInfo instance, so files are extracted with
5917 mode 0600 rather than 000 under Unix.
5918
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005919- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5920 argument in python 2.5, this broke code that subclassed Popen to include its
5921 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5936 regarding lack of coverage of new-style classes have also been
5937 removed, since the coverage is now fairly reasonable.

5947
Georg Brandl3e483f62008-07-16 22:57:41 +00005948- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5949 its methods now allow for items objects that can be converted to
5950 an integer using operator.index().
5951
Mark Dickinson64b7e502008-07-16 09:40:03 +00005952- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5953 produced a ValueError instead of giving the correct float.
5954
Eric Smitha5fa5a22008-07-16 00:11:49 +00005955- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

5957
Mark Dickinson7103aa42008-07-15 19:08:33 +00005958- Issue #3008: the float type has a new instance method 'float.hex'
5959 and a new class method 'float.fromhex' to convert floating-point
5960 numbers to and from hexadecimal strings, respectively.
5961
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005962- Issue #2235: __hash__ is once again inherited by default. To allow
5963 collections.Hashable to remain meaningful in the presence of the
5964 default hash implementation (object.__hash__), it is now possible
5965 to explicit block inheritance of hash by setting __hash__=None at
5966 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5967 level.
5968
Nick Coghlanb028f502008-07-13 14:52:36 +00005969- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5970 the parent module cannot be found while performing an absolute import.
5971 This means that an incorrectly defined __package__ attribute will
5972 now only prevent relative imports in that module rather than causing
5973 all imports from that module to fail.
5974
Nick Coghlan14ff9942008-07-08 14:21:42 +00005975- Issue #2517: Allow unicode messages in Exceptions again by correctly

5986
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005987- Issue #3004: Minor change to slice.indices(): the start and stop
5988 arguments are now treated identically, making the behaviour easier
5989 to describe and understand. For example, slice(None, -10,
5990 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5991 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5992 10, -1).

5996 from 2.4 caused by the switch to the new compiler.

6035 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006036 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00006508- Issue #1631171: Re-implement the 'warnings' module in C (the
6509 original Python code has been kept as backup). This will allow for
6510 using the 'warning's machinery in such places as the parser where
6511 use of pure Python code is not possible. Both the ``showarning()``
6512 and ``formatwarning()`` gain an optional 'line' argument which is

Georg Brandl3ee81df2008-05-17 18:14:43 +00006578- Issue #2550: The approach used by client/server code for obtaining
6579 ports to listen on in network-oriented tests has been refined in an
6580 effort to facilitate running multiple instances of the entire
6581 regression test suite in parallel without issue.
6582 test_support.bind_port() has been fixed such that it will always
6583 return a unique port -- which wasn't always the case with the
6584 previous implementation, especially if socket options had been set
6585 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6586 new implementation of bind_port() will actually raise an exception
6587 if it is passed an AF_INET/SOCK_STREAM socket with either the
6588 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6589 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6590 the socket it's been passed. This currently only applies to
6591 Windows. This option prevents any other sockets from binding to the
6592 host/port we've bound to, thus removing the possibility of the
6593 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6594 when a second SOCK_STREAM socket binds and accepts to a host/port
6595 that's already been bound by another socket. The optional preferred
6596 port parameter to bind_port() has been removed. Under no
6597 circumstances should tests be hard coding ports!
6598
6599 test_support.find_unused_port() has also been introduced, which will
6600 pass a temporary socket object to bind_port() in order to obtain an
6601 unused port. The temporary socket object is then closed and
6602 deleted, and the port is returned. This method should only be used
6603 for obtaining an unused port in order to pass to an external program
6604 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6605 a parameter to a server-oriented class that doesn't give you direct
6606 access to the underlying socket used.
6607
6608 Finally, test_support.HOST has been introduced, which should be used
6609 for the host argument of any relevant socket calls (i.e. bind and
6610 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006611
6612 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006613 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006614 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6615 test_asynchat and test_socket_ssl.
6616
Georg Brandl3ee81df2008-05-17 18:14:43 +00006617 It is now possible for multiple instances of the regression test
6618 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006897- Added the future_builtins module, which contains hex() and oct().
6898 These are the PEP 3127 version of these functions, designed to be
6899 compatible with the hex() and oct() builtins from Python 3.0. They
6900 differ slightly in their output formats from the existing, unchanged
6901 Python 2.6 builtins. The expected usage of the future_builtins
6902 module is:
6903 from future_builtins import hex, oct
6904
Eric Smith7ef40bf2008-02-20 23:34:22 +00006905- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6906 exponents for exponents with absolute value < 100. Follows C99
6907 standard. This is a change on Windows, which would use 3 digits.
6908 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6909 so that any alterations it does to the resulting string will be
6910 available in stringlib/formatter.h (for float.__format__).
6911
Eric Smith5a3c1352008-02-19 13:21:56 +00006912- Implemented PEP 3101, Advanced String Formatting. This adds a new
6913 builtin format(); a format() method for str and unicode; a
6914 __format__() method to object, str, unicode, int, long, float, and
6915 datetime; the class string.Formatter; and the C API
6916 PyObject_Format().
6917
Georg Brandl3ee81df2008-05-17 18:14:43 +00006918- Fixed several potential crashes, all caused by specially crafted
6919 __del__ methods exploiting objects in temporarily inconsistent
6920 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006921
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006922- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006923 prevent a possible crash: an Abstract Base Class would try to access
6924 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006925

Georg Brandl3ee81df2008-05-17 18:14:43 +00006929- Clear all free lists during a gc.collect() of the highest generation
6930 in order to allow pymalloc to free more arenas. Python may give back
6931 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006932
Georg Brandl3ee81df2008-05-17 18:14:43 +00006933- Issue #2045: Fix an infinite recursion triggered when printing a
6934 subclass of collections.defaultdict, if its default_factory is set
6935 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006936
Christian Heimesf75dbef2008-02-08 00:11:31 +00006937- Fixed a minor memory leak in dictobject.c. The content of the free
6938 list was not freed on interpreter shutdown.
6939
Georg Brandl21e99f42010-03-07 15:23:59 +00006940- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006941 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006942
Georg Brandl3ee81df2008-05-17 18:14:43 +00006943- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6944 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006945 to compact the internal free lists of pre-allocted ints and floats.
6946
Georg Brandl3ee81df2008-05-17 18:14:43 +00006947- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6948 calls. Python expected the return type int but the fork familie
6949 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006950
Georg Brandl3ee81df2008-05-17 18:14:43 +00006951- Issue #1678380: Fix a bug that identifies 0j and -0j when they

6961 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006962
Georg Brandl3ee81df2008-05-17 18:14:43 +00006963- Patch #1473257: generator objects gain a gi_code attribute. This is
6964 the same object as the func_code attribute of the function that
6965 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006966
Georg Brandl3ee81df2008-05-17 18:14:43 +00006967- Issue #1920: "while 0" statements were completely removed by the
6968 compiler, even in the presence of an "else" clause, which is
6969 supposed to be run when the condition is false. Now the compiler
6970 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006971
Guido van Rossumeead05f2008-01-24 18:21:02 +00006972- A few crashers fixed: weakref_in_del.py (issue #1377858);
6973 loosing_dict_ref.py (issue #1303614, test67.py);
6974 borrowed_ref_[34].py (not in tracker).
6975
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006976- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006977 suppressed while an extension is loaded by calling SetErrorMode in

6979
Georg Brandl3ee81df2008-05-17 18:14:43 +00006980- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006981 several extension methods and modules do not work without unicode
6982 support.
6983
Georg Brandl26543b12008-01-21 18:36:51 +00006984- Issue #1882: when compiling code from a string, encoding cookies in the
6985 second line of code were not always recognized correctly.
6986
Georg Brandl14404b62008-01-19 19:27:05 +00006987- Issue #1679: "0x" was taken as a valid integer literal.
6988
Georg Brandl6caad7d2008-01-26 14:19:22 +00006989- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006990 added.
6991
Christian Heimesc94e2b52008-01-14 04:13:37 +00006992- sys.float_info / PyFloat_GetInfo: The floating point information
6993 object was converted from a dict to a specialized structseq object.
6994
Georg Brandl3ee81df2008-05-17 18:14:43 +00006995- Patch #1816: Added sys.flags structseq. It exposes the status of
6996 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006997
Georg Brandl3ee81df2008-05-17 18:14:43 +00006998- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00007024 and INF. float("nan"), float("inf") and float("-inf") now work on
7025 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007027- Compiler now generates simpler and faster code for dictionary
7028 literals. The oparg for BUILD_MAP now indicates an estimated
7029 dictionary size. There is a new opcode, STORE_MAP, for adding
7030 entries to the dictionary.

7042
Nick Coghlanef01d822007-12-03 12:55:17 +00007043- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00007059- Patch #1739468: Directories and zipfiles containing a __main__.py
7060 file can now be directly executed by passing their name to the
7061 interpreter. The directory/zipfile is automatically inserted as the
7062 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007064- Issue #1265: Fix a problem with sys.settrace, if the tracing
7065 function uses a generator expression when at the same time the
7066 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007067
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007068- sets and frozensets now have an isdisjoint() method.

7073
Georg Brandl21e99f42010-03-07 15:23:59 +00007074- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007075 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7076 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007077
Georg Brandl3ee81df2008-05-17 18:14:43 +00007078- Issue #1686386: Tuple's tp_repr did not take into account the
7079 possibility of having a self-referential tuple, which is possible
7080 from C code. Nor did object's tp_str consider that a type's tp_str
7081 could do something that could lead to an inifinite recursion.
7082 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7083 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007084
Georg Brandl3ee81df2008-05-17 18:14:43 +00007085- Issue #1164: It was possible to trigger deadlock when using the
7086 'print' statement to write to a file since the GIL was not released
7087 as needed. Now PyObject_Print() does the right thing along with
7088 various tp_print implementations of the built-in types and those in
7089 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007090
Georg Brandl3ee81df2008-05-17 18:14:43 +00007091- Issue #1147: Exceptions were directly allowing string exceptions in
7092 their throw() method even though string exceptions no longer
7093 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007094
Georg Brandl3ee81df2008-05-17 18:14:43 +00007095- Issue #1096: Prevent a segfault from getting the repr of a very
7096 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007097
Brett Cannon1e534b52007-09-07 04:18:30 +00007098- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007099 PyObject_Call() never calling back out to Python code to trigger
7100 recursion depth updates/checks. Required the creation of a static
7101 RuntimeError instance in case normalizing an exception put the
7102 recursion check value past its limit. Fixes crashers
7103 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007104
Georg Brandl3ee81df2008-05-17 18:14:43 +00007105- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007118- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007119 __*__ attributes. (Some already existed, e.g., __doc__ and
7120 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007121
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007122- Add -3 option to the interpreter to warn about features that are
7123 deprecated and will be changed/removed in Python 3.0.
7124
Georg Brandl2134e752007-05-21 20:34:16 +00007125- Patch #1686487: you can now pass any mapping after '**' in function
7126 calls.
7127
Collin Winter62903052007-05-18 23:11:24 +00007128- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007129 "except E as target:". This is to provide forwards compatibility
7130 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007131
Brett Cannon229cee22007-05-05 01:34:02 +00007132- Deprecate BaseException.message as per PEP 352.
7133
Georg Brandl3ee81df2008-05-17 18:14:43 +00007134- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007135 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007136
Vinay Sajip8549ce32007-05-06 17:53:37 +00007137- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007138 setting a plain string, ie don't expand to single letter identifiers.
7139
Raymond Hettinger13936692007-04-11 18:40:58 +00007140- Request #1191699: Slices can now be pickled.
7141
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007142- Request #1193128: str.translate() now allows a None argument for
7143 translations that only remove characters without re-mapping the
7144 remaining characters.
7145
Georg Brandl5cb76c12007-03-21 09:00:39 +00007146- Patch #1682205: a TypeError while unpacking an iterable is no longer
7147 masked by a generic one with the message "unpack non-sequence".
7148
Neal Norwitzaa754b72007-03-21 06:39:48 +00007149- Remove unused file Python/fmod.c.
7150
Guido van Rossum143b5642007-03-23 04:58:42 +00007151- Bug #1683368: The object.__init__() and object.__new__() methods are
7152 now stricter in rejecting excess arguments. The only time when
7153 either allows excess arguments is when it is not overridden and the
7154 other one is. For backwards compatibility, when both are
7155 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007156 warning later). Also, type.__init__() insists on the same signature
7157 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007158
Georg Brandl3ee81df2008-05-17 18:14:43 +00007159- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7160 object to complex using its __complex__() method before falling back
7161 to the __float__() method. Therefore, the functions in the cmath
7162 module now can operate on objects that define a __complex__()
7163 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007164
Georg Brandl3ee81df2008-05-17 18:14:43 +00007165- Patch #1623563: allow __class__ assignment for classes with
7166 __slots__. The old and the new class are still required to have the
7167 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007168
Georg Brandl3ee81df2008-05-17 18:14:43 +00007169- Patch #1642547: Fix an error/crash when encountering syntax errors

7173 ``object.__reduce_ex__()`` is called with an object that is faking
7174 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007175
Georg Brandl3ee81df2008-05-17 18:14:43 +00007176- Patch #1680015: Don't modify __slots__ tuple if it contains an

7180
Georg Brandl7b9c5552007-03-12 14:30:05 +00007181- Bug #1678647: write a newline after printing an exception in any
7182 case, even when converting the value to a string failed.
7183
Georg Brandl871f1bc2007-03-12 13:17:36 +00007184- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007185 its argument, if it exists. If not, it will work like before. This
7186 allows customizing the output of dir() in the presence of a
7187 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007188
Collin Winter276887b2007-03-12 16:11:39 +00007189- Patch #922167: Python no longer segfaults when faced with infinitely
7190 self-recursive reload() calls (as reported by bug #742342).
7191
Georg Brandl3ee81df2008-05-17 18:14:43 +00007192- Patch #1675981: remove unreachable code from ``type.__new__()``
7193 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007195- Patch #1491866: change the complex() constructor to allow
7196 parthensized forms. This means complex(repr(x)) now works instead of
7197 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007198
Georg Brandlaa2321b2007-03-07 00:40:28 +00007199- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007200 makes the filenames the warning module prints much more sensible
7201 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007202
Georg Brandl49aafc92007-03-07 00:34:46 +00007203- Variant of patch #697613: don't exit the interpreter on a SystemExit
7204 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007205 variable is given, but break into the interactive interpreter just
7206 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00007213
Georg Brandl0fca97a2007-03-05 22:28:08 +00007214- Patch #1674228: when assigning a slice (old-style), check for the
7215 sq_ass_slice instead of the sq_slice slot.
7216
Georg Brandl3ee81df2008-05-17 18:14:43 +00007217- When printing an unraisable error, don't print exceptions. before
7218 the name. This duplicates the behavior whening normally printing
7219 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007770- Patch #1530482: add pydoc.render_doc() which returns the

7785
Georg Brandl92a6bae2007-03-13 17:43:32 +00007786- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007787 are set for invalid interpolation sequences that would lead to
7788 errors on reading back those values.

7844 TestCase and TestSuite subclasses (not instances) are no longer
7845 accepted in TestSuite.addTest(). This should cause no
7846 incompatibility since it never made sense with ordinary subclasses
7847 -- the failure just occurred later, with a more cumbersome
7848 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008135 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00008137 does not claim to support starttls. Adds the
8138 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008236- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008237 time so that opening a database previously created with the DB_DUP
8238 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8239 opens. Specifically: dictionary assignment to a DB object will
8240 replace all values for a given key when the database allows
8241 duplicate values. DB users should use DB.put(k, v) when they want
8242 to store duplicates; not DB[k] = v.

8250 dots only if they occur on a single line, as opposed to the previous
8251 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008521- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008522 periodic threadstate and signal checking in tight loops. By
8523 default, this option is turned-off. It should only be enabled in
8524 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00008581
Georg Brandl3ee81df2008-05-17 18:14:43 +00008582- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8583 to ``PyTuple_SetItem``, it can be used to populate a brand new

8596
Georg Brandl3ee81df2008-05-17 18:14:43 +00008597- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8598 of w# format code incorrectly truncated the length to an int, even
8599 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8600 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008601

8624 outside of pystate.c and should not be necessary.
8625
Georg Brandl3ee81df2008-05-17 18:14:43 +00008626- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8627 absolute imports. In earlier versions they might have used relative
8628 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008629
Georg Brandl3ee81df2008-05-17 18:14:43 +00008630- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8631 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008632
Georg Brandl3ee81df2008-05-17 18:14:43 +00008633- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
