Antoine Pitrou16166452011-07-12 22:04:20 +020018- Issue #12149: Update the method cache after a type's dictionnary gets
19 cleared by the garbage collector. This fixes a segfault when an instance
20 and its type get caught in a reference cycle, and the instance's
21 deallocator calls one of the methods on the type (e.g. when subclassing
22 IOBase). Diagnosis and patch by Davide Rizzo.
23
Victor Stinnerba8b3a22011-07-08 02:07:45 +020024- Issue #12501: Adjust callable() warning: callable() is only not supported in

29
Victor Stinnerd3c7e172011-05-30 23:49:13 +020030- Issue #1195: my_fgets() now always clears errors before calling fgets(). Fix
Victor Stinner08563d92011-05-30 23:44:13 +020031 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
32 raw_input() interrupted by CTRL+c.
33
Barry Warsawc5643282011-07-19 17:06:30 -040034- dict_proxy objects now display their contents rather than just the class

Victor Stinnere7901312011-07-05 14:08:01 +020069- Issue #12493: subprocess: Popen.communicate() now also handles EINTR errors

77
Ned Deily87e82bb2011-06-28 19:52:59 -070078- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
79 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
80 interpreter process. This could cause failures in non-Distutils subprocesses
81 and was unreliable since tests or user programs could modify the interpreter
82 environment after Distutils set it. Instead, have Distutils set the the
83 deployment target only in the environment of each build subprocess. It is
84 still possible to globally override the default by setting
85 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
86 greater or equal to the default value, the value with which the interpreter
87 was built.

93 Kitada.
94
R David Murrayf1138bb2011-06-17 22:23:04 -040095- Issue #11700: mailbox proxy object close methods can now be called multiple
96 times without error, and _ProxyFile now closes the wrapped file.
97
Victor Stinnerc74a6ba2011-06-17 14:06:27 +020098- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
99 connection if its getresponse() method fails with a socket error. Patch
100 written by Ezio Melotti.
101
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500102- Issue #9284: Allow inspect.findsource() to find the source of doctest
103 functions.
104
R David Murray873c5832011-06-09 16:01:09 -0400105- Issue #10694: zipfile now ignores garbage at the end of a zipfile.
106
Brian Curtincaea7e82011-06-08 19:29:53 -0500107- Issue #11583: Speed up os.path.isdir on Windows by using GetFileAttributes
108 instead of os.stat.
109
Mark Dickinsona493ca32011-06-04 18:24:15 +0100110- Issue #12080: Fix a performance issue in Decimal._power_exact that caused
111 some corner-case Decimal.__pow__ calls to take an unreasonably long time.
112
Raymond Hettinger45b08292011-06-02 20:40:35 -0700113- Named tuples now work correctly with vars().
114
Barry Warsawc5643282011-07-19 17:06:30 -0400115- sys.setcheckinterval() now updates the current ticker count as well as
116 updating the check interval, so if the user decreases the check interval,
117 the ticker doesn't have to wind down to zero from the old starting point
118 before the new interval takes effect. And if the user increases the
119 interval, it makes sure the new limit takes effect right away rather have an
120 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700121
Victor Stinner776e69b2011-06-01 01:03:00 +0200122- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the
123 constructor has failed, e.g. because of an undeclared keyword argument. Patch

159 test_tk or test_ttk_guionly under a username that is not currently logged
160 in to the console windowserver (as may be the case under buildbot or ssh).
161
Ned Deily63144c62011-06-28 00:39:19 -0700162- Issue #12141: Install a copy of template C module file so that

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

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001430- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1431 start byte and the continuation byte(s) are now considered invalid, instead
1432 of the number of bytes specified by the start byte.
1433 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1434 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1445 objects. (1) The comparison could incorrectly return True in some cases
1446 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001791 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1792 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1793 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1814-----------------
1815
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001816- Issue #7301: Add environment variable $PYTHONWARNINGS.
1817
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001818- Issue #8329: Don't return the same lists from select.select when no fds are
1819 changed.
1820
Georg Brandlfee0f442010-05-22 21:26:21 +00001821- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001822 on 64-bit machines. The shift count for either left or right shift is
1823 permitted to be up to sys.maxsize.
1824
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001825- Ensure that tokenization of identifiers is not affected by locale.
1826
Georg Brandlfee0f442010-05-22 21:26:21 +00001827- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001828
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001829- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1830
Georg Brandlfee0f442010-05-22 21:26:21 +00001831- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1832 with a non-empty format string. This is an effort to future-proof user
1833 code. If a derived class does not currently implement __format__ but later
1834 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001835 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001836 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001837
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001838- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00001851- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001852 (SIGINT). If an error occurs while importing the site module, the error is

1868
Georg Brandlfee0f442010-05-22 21:26:21 +00001869- Issue #8257: The Decimal construct now accepts a float instance directly,
1870 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001871
1872 >>> Decimal(1.1)
1873 Decimal('1.100000000000000088817841970012523233890533447265625')
1874
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001875- collections.Counter() now supports a subtract() method.
1876
Georg Brandlfee0f442010-05-22 21:26:21 +00001877- The functools module now has a total_ordering() class decorator to simplify
1878 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001879
Georg Brandlfee0f442010-05-22 21:26:21 +00001880- The functools module also adds cmp_to_key() as a tool to transition old-style
1881 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001882

Georg Brandlfee0f442010-05-22 21:26:21 +00001886- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1887 InvalidOperation instead of returning False. (Comparisons involving a quiet
1888 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1889 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001890
Georg Brandlfee0f442010-05-22 21:26:21 +00001891- Issue #2531: Comparison operations between floats and Decimal instances now
1892 return a result based on the numeric values of the operands; previously they
1893 returned an arbitrary result based on the relative ordering of id(float) and
1894 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001895
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001896- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001897 argument `-` which tells it to read files to compile from stdin. Each line is
1898 read on demand and the named file is compiled immediately. (Original patch by
1899 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00001904- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1905 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001906 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001907
Georg Brandlfee0f442010-05-22 21:26:21 +00001908- Comparisons using one of <, <=, >, >= between a complex instance and a
1909 Fractions instance now raise TypeError instead of returning True/False. This
1910 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1911 <=> complex, and complex <=> complex comparisons.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001966- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001967 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1968 log file to compute the next rollover time. If the log file does not exist,
1969 the current time is used as the basis for the computation.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002010- Issue #8300: When passing a non-integer argument to struct.pack with any
2011 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002015- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2016 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2017 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002018 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2019 inconsistent: __int__ was used for some integer codes but not for others, and
2020 the set of integer codes for which it was used differed between native packing
2021 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002329 file position when calling `truncate()`. It would previously change the file
2330 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002331 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2334 class used to represent files stored inside an archive. The new
2335 implementation is significantly faster and can be wrapped in a
2336 ``io.BufferedReader`` object for more speedups. It also solves an issue
2337 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2350 encoded string for them. This ensures that the upload and register commands
2351 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002622- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2623 decimal string that's guaranteed to round back to x under correct rounding
2624 (with round-half-to-even rounding mode). Previously it gave a string based on
2625 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2626 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2627 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002628
Georg Brandlba83f822010-03-14 09:50:54 +00002629- Issue #7117: On almost all platforms: float-to-string and string-to-float
2630 conversions within Python are now correctly rounded. Places these conversions
2631 occur include: str for floats and complex numbers; the float and complex
2632 constructors; old-style and new-style numeric formatting; serialization and
2633 deserialization of floats and complex numbers using marshal, pickle and json;
2634 parsing of float and imaginary literals in Python code; Decimal-to-float
2635 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002636
Georg Brandlba83f822010-03-14 09:50:54 +00002637 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2638 providing correctly-rounded strtod and dtoa C functions. This code is
2639 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2640 the C compiler. There may be a small number of platforms on which correct
2641 operation of this code cannot be guaranteed, so the code is not used: notably,
2642 this applies to platforms where the C double format is not IEEE 754 binary64,
2643 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2644 and Python's configure script is unable to determine how to change the FPU
2645 precision. On these platforms conversions use the platform strtod and dtoa,
2646 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002648- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2649 uses the correctly-rounded string <-> float conversions described above (when
2650 available), and so produces correctly rounded results that will display nicely
2651 under the float repr. There are two related small changes: (1) round now
2652 accepts any class with an ``__index__()`` method for its second argument (but
2653 no longer accepts floats for the second argument), and (2) an excessively
2654 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2655 raises an exception.

2804 but with at least one decimal point and with a default precision
2805 of 12. Previously, the behavior the same but with a default precision of 6.
2806 This more closely matches ``str()``, and reduces surprises when adding

2920
Benjamin Peterson596d3062009-01-19 15:42:23 +00002921- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00002948- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2949 existing .py counterpart, override the co_filename attributes of all code
2950 objects if the original filename is obsolete (which can happen if the file has

3005
Georg Brandlba83f822010-03-14 09:50:54 +00003006- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3007 file objects with closefd=False. The file descriptor is still kept open but
3008 the file object behaves like a closed file. The ``FileIO`` object also got a
3009 new readonly attribute ``closefd``.

3028
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003029- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003032- On windows, ``os.chdir()`` given unicode was not working if
3033 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3034 this code path is really executed because I cannot move to such directory on
3035 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003037- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3038 element is temporarily replaced with an equivalent frozenset. But the
3039 eventual KeyError would always report the empty ``frozenset()`` as the missing
3040 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003060- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3061 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3062 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3063 of using the replace error handler in PyUnicode_DecodeUTF8().
3064
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003065- Issue #3739: The unicode-internal encoder now reports the number of characters

3067
Georg Brandlba83f822010-03-14 09:50:54 +00003068- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3070 gives improved memory leak detection when running under Valgrind, while taking
3071 advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00003143 __main__.py file. This allows applications that run other Python scripts to
3144 support the same flexibility as the CPython command line itself.

4437
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004438- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4439 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4440 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4441 ``printf`` function, whereas PyString_FromFormat has an independent
4442 implementation and uses "%zd" on all platforms for size_t values.
4443 This makes a difference on win64, where ``printf`` needs "%Id" to display
4444 64bit values.

4450 object; previously an int would be returned for small values. the __long__

4462
Vinay Sajip35e3b032008-09-01 14:33:59 +00004463- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004464 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4465 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4466 when given a tuple of classes as second argument, were looking up
4467 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4468 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004539 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4540 for catch_warnings() also led to an improvement in the raising of a
4541 DeprecationWarning related to warnings.warn_explicit().
4542
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004543- The deprecation warnings for the old camelCase threading API were removed.
4544

4546
Christian Heimesa27a62e2008-08-22 19:55:54 +00004547- Silenced a trivial compiler warning in the sqlite module.
4548
Christian Heimes1cc69632008-08-22 20:10:27 +00004549- Fixed two format strings in the _collections module.
4550

4562
Jesse Noller438195f2009-01-18 21:04:36 +00004563- Issue #4301: Patch the logging module to add processName support, remove
4564 _check_logger_class from multiprocessing.
4565
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004566- Issue #2975: When compiling several extension modules with Visual Studio 2008
4567 from the same python interpreter, some environment variables would grow
4568 without limit.
4569
Benjamin Peterson37346b22008-08-23 20:27:43 +00004570- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4571 exploitation of poor argument checking.
4572
Gerhard Häringef2276b2008-09-12 13:54:06 +00004573- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4574
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004575- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4576 remaining ones have "pysqlite_" prefix.
4577
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004578- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

4586 wrapper for warnings.catch_warnings() that makes it easier to check
4587 that expected warning messages are being reported.
4588
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00004589- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004607What's New in Python 2.6 beta 3?
4608================================
4609
Barry Warsaw07a4a382008-08-21 01:15:08 +00004610*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004611
4612Core and Builtins
4613-----------------
4614
Guido van Rossumf8402962008-08-20 15:01:50 +00004615- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4616 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4617 extensions do not automatically benefit from the class attribute
4618 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4619 to their tp_flags field if they care. This is a backwards
4620 compatibility feature; in 3.0, all types will use the cache by
4621 default.
4622
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004623- Keyword arguments can now follow starred arguments. (``f(a, *args,
4624 keyword=23)`` is now valid syntax.)
4625
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004626- ctypes function pointers that are COM methods have a boolean True
4627 value again.
4628
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004629- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4630 by denying s# to parse objects that have a releasebuffer procedure,
4631 and introducing s*.
4632
Georg Brandl1e13ea92008-08-11 09:07:59 +00004633- Issue #3537: Fix an assertion failure when an empty but presized dict
4634 object was stored in the freelist.
4635
Mark Dickinsonb6467572008-08-04 21:30:09 +00004636- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4637 ValueError consistently across platforms.
4638
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004639- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4640 (64bit Unix, for example), unichr() would truncate its argument and return
4641 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4642
Neal Norwitze7d8be82008-07-31 17:17:14 +00004643- Apply security patches from Apple.
4644
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004645- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4646 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4647
Antoine Pitrou92f82162008-07-25 22:22:08 +00004648- Issue #1819: function calls with several named parameters are now on
4649 average 35% faster (as measured by pybench).
4650
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004651- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4652 the python debugger steps into a class statement: the free variables (local
4653 variables defined in an outer scope) would be deleted from the outer scope.
4654
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004655- Issue #2620: Overflow checking when allocating or reallocating memory
4656 was not always being done properly in some python types and extension
4657 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4658 all been updated to perform better checks and places in the code that
4659 would previously leak memory on the error path when such an allocation
4660 failed have been fixed.
4661
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004662Library
4663-------
4664
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004665- Issue #3612: Added some missing basic types in ctypes.wintypes.
4666
Benjamin Petersone977ad42008-08-20 01:42:01 +00004667- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4668 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4669
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004670- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4671 version reported by these tools does not necessarily follow the python
4672 version numbering scheme, so the module is less strict when parsing it.
4673
Nick Coghlanf70385a2008-08-18 12:42:46 +00004674- Issue #2235: Added Py3k warnings for types which will become unhashable
4675 under the stricter __hash__ inheritance rules in 3.0. Several types
4676 which did not meet the rules for hash invariants and were already
4677 unhashable in 3.0 have now been explicitly flagged as unhashable in
4678 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4679 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4680
Brett Cannon88f801d2008-08-18 00:46:22 +00004681- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4682 imported into the module but exposed as part of the module's API.
4683
Brett Cannon7b96f072008-08-18 00:41:11 +00004684- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4685
Brett Cannon46225e72008-08-18 00:36:52 +00004686- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004688- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4689
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004690- Issue #3575: Incremental decoder's decode function now takes bytearray
4691 by using 's*' instead of 't#'.
4692
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004693- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004694 fails unicode conversion on 2nd parameter. (windows only)
4695
Georg Brandl222e2082010-08-01 22:27:39 +00004696- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004697 in a redirect.
4698
Brett Cannonabe423e2008-08-16 21:47:07 +00004699- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004700 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004701
Facundo Batistaeb90b782008-08-16 14:44:07 +00004702- Issue #2776: fixed small issue when handling an URL with double slash
4703 after a 302 response in the case of not going through a proxy.
4704
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004705- Issue #2676: in the email package, content-type parsing was hanging on
4706 pathological input because of quadratic or exponential behaviour of a
4707 regular expression.
4708
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004709- Issue #3476: binary buffered reading through the new "io" library is now
4710 thread-safe.
4711
Brett Cannonbf3157b2008-08-14 05:00:03 +00004712- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4713 since mimetools itself is deprecated. Because modules are cached, all
4714 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4715
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004716- Issue #3134: shutil referenced undefined WindowsError symbol.
4717
Robert Schuppenies14646332008-08-10 11:01:53 +00004718- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4719 menu entries were not deleted.
4720
Brett Cannon83e81842008-08-09 23:30:55 +00004721- Copied the implementation of reduce() to _functools.reduce() to have a
4722 version that did not raise a DeprecationWarning under -3.
4723
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004724- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4725 a MemoryError rather than silently stop the iteration.
4726
Guido van Rossum59ce9012008-08-09 14:55:34 +00004727- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4728 to _sre.compile() will now be rejected. This should not affect anybody
4729 since the re.compile() function never generates invalid re-bytecode.
4730
Skip Montanaroa032bf42008-08-08 22:52:51 +00004731- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4732 upon first access it can be automatically initialized from the csv file if
4733 it wasn't initialized during instantiation.
4734
Brett Cannon3aa2a492008-08-06 22:28:09 +00004735- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4736 the reload() built-in has been removed.
4737
Brett Cannon7e30b672008-08-04 21:52:25 +00004738- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004739 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004750 asking for a specific length. This problem only affected files opened
4751 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004752

4777 file name rather than a ZipInfo instance, so files are extracted with
4778 mode 0600 rather than 000 under Unix.
4779
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004780- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4781 argument in python 2.5, this broke code that subclassed Popen to include its
4782 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4796 coverage of the lookup process for special methods. The disclaimers
4797 regarding lack of coverage of new-style classes have also been
4798 removed, since the coverage is now fairly reasonable.

4807-----------------
4808
Georg Brandl3e483f62008-07-16 22:57:41 +00004809- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4810 its methods now allow for items objects that can be converted to
4811 an integer using operator.index().
4812
Mark Dickinson64b7e502008-07-16 09:40:03 +00004813- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4814 produced a ValueError instead of giving the correct float.
4815
Eric Smitha5fa5a22008-07-16 00:11:49 +00004816- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4817 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4818
Mark Dickinson7103aa42008-07-15 19:08:33 +00004819- Issue #3008: the float type has a new instance method 'float.hex'
4820 and a new class method 'float.fromhex' to convert floating-point
4821 numbers to and from hexadecimal strings, respectively.
4822
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004823- Issue #2235: __hash__ is once again inherited by default. To allow
4824 collections.Hashable to remain meaningful in the presence of the

Nick Coghlanb028f502008-07-13 14:52:36 +00004830- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4831 the parent module cannot be found while performing an absolute import.
4832 This means that an incorrectly defined __package__ attribute will
4833 now only prevent relative imports in that module rather than causing
4834 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004848- Issue #3004: Minor change to slice.indices(): the start and stop
4849 arguments are now treated identically, making the behaviour easier
4850 to describe and understand. For example, slice(None, -10,
4851 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4852 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4853 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00005307 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005308

5356 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005357
Christian Heimese74c8f22008-04-19 02:23:57 +00005358- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005369- Issue #1631171: Re-implement the 'warnings' module in C (the
5370 original Python code has been kept as backup). This will allow for
5371 using the 'warning's machinery in such places as the parser where
5372 use of pure Python code is not possible. Both the ``showarning()``
5373 and ``formatwarning()`` gain an optional 'line' argument which is
5374 not called by default for backwards-compatibility reasons. Setting
5375 ``warnings.showwarning()`` to an implementation that lacks support
5376 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005439- Issue #2550: The approach used by client/server code for obtaining
5440 ports to listen on in network-oriented tests has been refined in an
5441 effort to facilitate running multiple instances of the entire
5442 regression test suite in parallel without issue.
5443 test_support.bind_port() has been fixed such that it will always
5444 return a unique port -- which wasn't always the case with the
5445 previous implementation, especially if socket options had been set
5446 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5447 new implementation of bind_port() will actually raise an exception
5448 if it is passed an AF_INET/SOCK_STREAM socket with either the
5449 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5450 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5451 the socket it's been passed. This currently only applies to
5452 Windows. This option prevents any other sockets from binding to the
5453 host/port we've bound to, thus removing the possibility of the
5454 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5455 when a second SOCK_STREAM socket binds and accepts to a host/port
5456 that's already been bound by another socket. The optional preferred
5457 port parameter to bind_port() has been removed. Under no
5458 circumstances should tests be hard coding ports!
5459
5460 test_support.find_unused_port() has also been introduced, which will
5461 pass a temporary socket object to bind_port() in order to obtain an
5462 unused port. The temporary socket object is then closed and
5463 deleted, and the port is returned. This method should only be used
5464 for obtaining an unused port in order to pass to an external program
5465 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5466 a parameter to a server-oriented class that doesn't give you direct
5467 access to the underlying socket used.
5468
5469 Finally, test_support.HOST has been introduced, which should be used
5470 for the host argument of any relevant socket calls (i.e. bind and
5471 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005472
5473 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005474 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005475 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5476 test_asynchat and test_socket_ssl.
5477
Georg Brandl3ee81df2008-05-17 18:14:43 +00005478 It is now possible for multiple instances of the regression test
5479 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005758- Added the future_builtins module, which contains hex() and oct().
5759 These are the PEP 3127 version of these functions, designed to be
5760 compatible with the hex() and oct() builtins from Python 3.0. They
5761 differ slightly in their output formats from the existing, unchanged
5762 Python 2.6 builtins. The expected usage of the future_builtins
5763 module is:
5764 from future_builtins import hex, oct
5765
Eric Smith7ef40bf2008-02-20 23:34:22 +00005766- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5767 exponents for exponents with absolute value < 100. Follows C99
5768 standard. This is a change on Windows, which would use 3 digits.
5769 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5770 so that any alterations it does to the resulting string will be
5771 available in stringlib/formatter.h (for float.__format__).
5772
Eric Smith5a3c1352008-02-19 13:21:56 +00005773- Implemented PEP 3101, Advanced String Formatting. This adds a new
5774 builtin format(); a format() method for str and unicode; a
5775 __format__() method to object, str, unicode, int, long, float, and
5776 datetime; the class string.Formatter; and the C API
5777 PyObject_Format().
5778
Georg Brandl3ee81df2008-05-17 18:14:43 +00005779- Fixed several potential crashes, all caused by specially crafted
5780 __del__ methods exploiting objects in temporarily inconsistent
5781 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005782
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005783- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005784 prevent a possible crash: an Abstract Base Class would try to access
5785 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005786

Georg Brandl3ee81df2008-05-17 18:14:43 +00005790- Clear all free lists during a gc.collect() of the highest generation
5791 in order to allow pymalloc to free more arenas. Python may give back
5792 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005793
Georg Brandl3ee81df2008-05-17 18:14:43 +00005794- Issue #2045: Fix an infinite recursion triggered when printing a
5795 subclass of collections.defaultdict, if its default_factory is set
5796 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005797
Christian Heimesf75dbef2008-02-08 00:11:31 +00005798- Fixed a minor memory leak in dictobject.c. The content of the free
5799 list was not freed on interpreter shutdown.
5800
Georg Brandl21e99f42010-03-07 15:23:59 +00005801- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005803
Georg Brandl3ee81df2008-05-17 18:14:43 +00005804- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5805 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005806 to compact the internal free lists of pre-allocted ints and floats.
5807
Georg Brandl3ee81df2008-05-17 18:14:43 +00005808- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5809 calls. Python expected the return type int but the fork familie
5810 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005811
Georg Brandl3ee81df2008-05-17 18:14:43 +00005812- Issue #1678380: Fix a bug that identifies 0j and -0j when they

5822 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005823
Georg Brandl3ee81df2008-05-17 18:14:43 +00005824- Patch #1473257: generator objects gain a gi_code attribute. This is
5825 the same object as the func_code attribute of the function that
5826 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005827
Georg Brandl3ee81df2008-05-17 18:14:43 +00005828- Issue #1920: "while 0" statements were completely removed by the
5829 compiler, even in the presence of an "else" clause, which is
5830 supposed to be run when the condition is false. Now the compiler
5831 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005832
Guido van Rossumeead05f2008-01-24 18:21:02 +00005833- A few crashers fixed: weakref_in_del.py (issue #1377858);
5834 loosing_dict_ref.py (issue #1303614, test67.py);
5835 borrowed_ref_[34].py (not in tracker).
5836
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005837- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005838 suppressed while an extension is loaded by calling SetErrorMode in

5840
Georg Brandl3ee81df2008-05-17 18:14:43 +00005841- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005842 several extension methods and modules do not work without unicode
5843 support.
5844
Georg Brandl26543b12008-01-21 18:36:51 +00005845- Issue #1882: when compiling code from a string, encoding cookies in the
5846 second line of code were not always recognized correctly.
5847
Georg Brandl14404b62008-01-19 19:27:05 +00005848- Issue #1679: "0x" was taken as a valid integer literal.
5849
Georg Brandl6caad7d2008-01-26 14:19:22 +00005850- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005851 added.
5852
Christian Heimesc94e2b52008-01-14 04:13:37 +00005853- sys.float_info / PyFloat_GetInfo: The floating point information
5854 object was converted from a dict to a specialized structseq object.
5855
Georg Brandl3ee81df2008-05-17 18:14:43 +00005856- Patch #1816: Added sys.flags structseq. It exposes the status of
5857 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005858
Georg Brandl3ee81df2008-05-17 18:14:43 +00005859- Objects/structseq.c: Implemented new structseq representation. The
5860 patch makes structseqs (e.g. the return value of os.stat) more
5861 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005862
Georg Brandl3ee81df2008-05-17 18:14:43 +00005863- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005875- Improve some exception messages when Windows fails to load an
5876 extension module. Now we get for example '%1 is not a valid Win32
5877 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005885 and INF. float("nan"), float("inf") and float("-inf") now work on
5886 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005887
Georg Brandl3ee81df2008-05-17 18:14:43 +00005888- Compiler now generates simpler and faster code for dictionary
5889 literals. The oparg for BUILD_MAP now indicates an estimated

Georg Brandl3ee81df2008-05-17 18:14:43 +00005939- Issue #1686386: Tuple's tp_repr did not take into account the
5940 possibility of having a self-referential tuple, which is possible
5941 from C code. Nor did object's tp_str consider that a type's tp_str
5942 could do something that could lead to an inifinite recursion.
5943 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5944 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005960 PyObject_Call() never calling back out to Python code to trigger
5961 recursion depth updates/checks. Required the creation of a static

6011
Guido van Rossum143b5642007-03-23 04:58:42 +00006012- Bug #1683368: The object.__init__() and object.__new__() methods are
6013 now stricter in rejecting excess arguments. The only time when
6014 either allows excess arguments is when it is not overridden and the
6015 other one is. For backwards compatibility, when both are
6016 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006017 warning later). Also, type.__init__() insists on the same signature
6018 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006020- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6021 object to complex using its __complex__() method before falling back
6022 to the __float__() method. Therefore, the functions in the cmath
6023 module now can operate on objects that define a __complex__()
6024 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006042- Bug #1678647: write a newline after printing an exception in any
6043 case, even when converting the value to a string failed.
6044
Georg Brandl871f1bc2007-03-12 13:17:36 +00006045- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006046 its argument, if it exists. If not, it will work like before. This
6047 allows customizing the output of dir() in the presence of a
6048 __getattr__().

6058 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006059
Georg Brandlaa2321b2007-03-07 00:40:28 +00006060- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006061 makes the filenames the warning module prints much more sensible
6062 when a PYTHONSTARTUP file is used.

6077
Georg Brandl3ee81df2008-05-17 18:14:43 +00006078- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00006631- Patch #1530482: add pydoc.render_doc() which returns the

6646
Georg Brandl92a6bae2007-03-13 17:43:32 +00006647- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006648 are set for invalid interpolation sequences that would lead to

6705 TestCase and TestSuite subclasses (not instances) are no longer
6706 accepted in TestSuite.addTest(). This should cause no
6707 incompatibility since it never made sense with ordinary subclasses
6708 -- the failure just occurred later, with a more cumbersome
6709 exception.

6993 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006994
Georg Brandl3ee81df2008-05-17 18:14:43 +00006995- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006996 that the SMTP.starttls() caller no longer needs to call ehlo()
6997 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006998 does not claim to support starttls. Adds the
6999 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00007083

Georg Brandl3ee81df2008-05-17 18:14:43 +00007098 time so that opening a database previously created with the DB_DUP
7099 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7100 opens. Specifically: dictionary assignment to a DB object will
7101 replace all values for a given key when the database allows

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007382- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007383 periodic threadstate and signal checking in tight loops. By
7384 default, this option is turned-off. It should only be enabled in
7385 debugged, performance critical applications.

7441 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007442
Georg Brandl3ee81df2008-05-17 18:14:43 +00007443- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7444 to ``PyTuple_SetItem``, it can be used to populate a brand new
7445 frozenset; but it does not steal a reference to the added item.

7457
Georg Brandl3ee81df2008-05-17 18:14:43 +00007458- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7459 of w# format code incorrectly truncated the length to an int, even
7460 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7461 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007462

7485 outside of pystate.c and should not be necessary.
7486
Georg Brandl3ee81df2008-05-17 18:14:43 +00007487- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

Georg Brandl3ee81df2008-05-17 18:14:43 +00007491- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7492 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007493
Georg Brandl3ee81df2008-05-17 18:14:43 +00007494- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00007519- Removed the macfs module. It had been deprecated since Python 2.5.
7520 This lead to the deprecation of macostools.touched() as it relied
