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

48 Linux 3.0.
49
R David Murray95225952011-07-18 21:34:04 -040050- Issue #7484: smtplib no longer puts <> around addresses in VRFY and EXPN
51 commands; they aren't required and in fact postfix doesn't support that form.
52
Antoine Pitrou304f0f92011-07-15 21:22:50 +020053- Issue #11603: Fix a crash when __str__ is rebound as __repr__. Patch by

68 the garbage collector while the Heap lock is held.
69
Ned Deily87e82bb2011-06-28 19:52:59 -070070- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
71 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
72 interpreter process. This could cause failures in non-Distutils subprocesses
73 and was unreliable since tests or user programs could modify the interpreter
74 environment after Distutils set it. Instead, have Distutils set the the
75 deployment target only in the environment of each build subprocess. It is
76 still possible to globally override the default by setting
77 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
78 greater or equal to the default value, the value with which the interpreter
79 was built.

85 Kitada.
86
R David Murrayf1138bb2011-06-17 22:23:04 -040087- Issue #11700: mailbox proxy object close methods can now be called multiple
88 times without error, and _ProxyFile now closes the wrapped file.
89
Victor Stinnerc74a6ba2011-06-17 14:06:27 +020090- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
91 connection if its getresponse() method fails with a socket error. Patch
92 written by Ezio Melotti.
93
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -050094- Issue #9284: Allow inspect.findsource() to find the source of doctest
95 functions.
96
R David Murray873c5832011-06-09 16:01:09 -040097- Issue #10694: zipfile now ignores garbage at the end of a zipfile.
98
Brian Curtincaea7e82011-06-08 19:29:53 -050099- Issue #11583: Speed up os.path.isdir on Windows by using GetFileAttributes
100 instead of os.stat.
101

106
Barry Warsawc5643282011-07-19 17:06:30 -0400107- sys.setcheckinterval() now updates the current ticker count as well as
108 updating the check interval, so if the user decreases the check interval,
109 the ticker doesn't have to wind down to zero from the old starting point
110 before the new interval takes effect. And if the user increases the
111 interval, it makes sure the new limit takes effect right away rather have an
112 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700113
Victor Stinner776e69b2011-06-01 01:03:00 +0200114- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

129 os.lchflags() are once again built on systems that support these
130 functions (*BSD and OS X). Also add new stat file flags for OS X
131 (UF_HIDDEN and UF_COMPRESSED).

151 test_tk or test_ttk_guionly under a username that is not currently logged
152 in to the console windowserver (as may be the case under buildbot or ssh).
153
Ned Deily63144c62011-06-28 00:39:19 -0700154- Issue #12141: Install a copy of template C module file so that

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

969 original error is re-raised.

990
R. David Murray7c4bf552010-08-25 01:45:57 +0000991- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
992 character years even if the message contains RFC822 two character years.
993
Daniel Stutzbach91287322010-08-24 21:09:30 +0000994- Issue #8750: Fixed MutableSet's methods to correctly handle
995 reflexive operations, namely x -= x and x ^= x.

1013
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001014- Issue #9626: the view methods for collections.OrderedDict() were returning

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001026- Issue #9550: a BufferedReader could issue an additional read when the
1027 original read request had been satisfied, which could block indefinitely
1028 when the underlying raw IO channel was e.g. a socket. Report and original
1029 patch by Jason V. Miller.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001419- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1420 start byte and the continuation byte(s) are now considered invalid, instead
1421 of the number of bytes specified by the start byte.
1422 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1423 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1434 objects. (1) The comparison could incorrectly return True in some cases
1435 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1436 (2) The comparison raised an OverflowError for large integers, leading

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001780 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1781 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1782 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1802Core and Builtins
1803-----------------
1804
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001805- Issue #7301: Add environment variable $PYTHONWARNINGS.
1806
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001807- Issue #8329: Don't return the same lists from select.select when no fds are
1808 changed.
1809
Georg Brandlfee0f442010-05-22 21:26:21 +00001810- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001811 on 64-bit machines. The shift count for either left or right shift is
1812 permitted to be up to sys.maxsize.
1813
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001814- Ensure that tokenization of identifiers is not affected by locale.
1815
Georg Brandlfee0f442010-05-22 21:26:21 +00001816- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001817
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001818- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1819
Georg Brandlfee0f442010-05-22 21:26:21 +00001820- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1821 with a non-empty format string. This is an effort to future-proof user
1822 code. If a derived class does not currently implement __format__ but later
1823 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001824 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001825 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001826
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001827- Issue #8268: Old-style classes (not just instances) now support weak

1836 arguments to a function correct.
1837
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00001838- Issue #8164: Don't allow lambda functions to have a docstring.
1839
Victor Stinner66644262010-03-10 22:30:19 +00001840- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001841 (SIGINT). If an error occurs while importing the site module, the error is
1842 printed and Python exits. Initialize the GIL before importing the site

1857
Georg Brandlfee0f442010-05-22 21:26:21 +00001858- Issue #8257: The Decimal construct now accepts a float instance directly,
1859 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001860
1861 >>> Decimal(1.1)
1862 Decimal('1.100000000000000088817841970012523233890533447265625')
1863
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001864- collections.Counter() now supports a subtract() method.
1865
Georg Brandlfee0f442010-05-22 21:26:21 +00001866- The functools module now has a total_ordering() class decorator to simplify
1867 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001868
Georg Brandlfee0f442010-05-22 21:26:21 +00001869- The functools module also adds cmp_to_key() as a tool to transition old-style
1870 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001871
Georg Brandlfee0f442010-05-22 21:26:21 +00001872- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1873 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001874
Georg Brandlfee0f442010-05-22 21:26:21 +00001875- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1876 InvalidOperation instead of returning False. (Comparisons involving a quiet
1877 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1878 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001879
Georg Brandlfee0f442010-05-22 21:26:21 +00001880- Issue #2531: Comparison operations between floats and Decimal instances now
1881 return a result based on the numeric values of the operands; previously they
1882 returned an arbitrary result based on the relative ordering of id(float) and
1883 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001884
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001885- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001886 argument `-` which tells it to read files to compile from stdin. Each line is
1887 read on demand and the named file is compiled immediately. (Original patch by
1888 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001889
Georg Brandlfee0f442010-05-22 21:26:21 +00001890- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001893- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1894 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001895 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001896
Georg Brandlfee0f442010-05-22 21:26:21 +00001897- Comparisons using one of <, <=, >, >= between a complex instance and a
1898 Fractions instance now raise TypeError instead of returning True/False. This
1899 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1900 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001901

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001911- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001912 didn't support chflags() (for example ZFS under FreeBSD). The error is now
1913 silenced.

Antoine Pitroud840e512010-02-04 20:20:18 +00002310- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002311 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002317- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002318 file position when calling `truncate()`. It would previously change the file
2319 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002320 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2321
Georg Brandlba83f822010-03-14 09:50:54 +00002322- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2323 class used to represent files stored inside an archive. The new
2324 implementation is significantly faster and can be wrapped in a
2325 ``io.BufferedReader`` object for more speedups. It also solves an issue
2326 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2327 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002337- Issue #7748: Since unicode values are supported for some metadata options in
2338 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2339 encoded string for them. This ensures that the upload and register commands
2340 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002611- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2612 decimal string that's guaranteed to round back to x under correct rounding
2613 (with round-half-to-even rounding mode). Previously it gave a string based on
2614 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2615 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2616 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002617
Georg Brandlba83f822010-03-14 09:50:54 +00002618- Issue #7117: On almost all platforms: float-to-string and string-to-float
2619 conversions within Python are now correctly rounded. Places these conversions
2620 occur include: str for floats and complex numbers; the float and complex
2621 constructors; old-style and new-style numeric formatting; serialization and
2622 deserialization of floats and complex numbers using marshal, pickle and json;
2623 parsing of float and imaginary literals in Python code; Decimal-to-float
2624 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002625
Georg Brandlba83f822010-03-14 09:50:54 +00002626 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2627 providing correctly-rounded strtod and dtoa C functions. This code is
2628 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2629 the C compiler. There may be a small number of platforms on which correct
2630 operation of this code cannot be guaranteed, so the code is not used: notably,
2631 this applies to platforms where the C double format is not IEEE 754 binary64,
2632 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2633 and Python's configure script is unable to determine how to change the FPU
2634 precision. On these platforms conversions use the platform strtod and dtoa,
2635 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002637- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2638 uses the correctly-rounded string <-> float conversions described above (when
2639 available), and so produces correctly rounded results that will display nicely
2640 under the float repr. There are two related small changes: (1) round now
2641 accepts any class with an ``__index__()`` method for its second argument (but
2642 no longer accepts floats for the second argument), and (2) an excessively
2643 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2644 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002791- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2792 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2793 but with at least one decimal point and with a default precision
2794 of 12. Previously, the behavior the same but with a default precision of 6.
2795 This more closely matches ``str()``, and reduces surprises when adding

2797 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00003021- On windows, ``os.chdir()`` given unicode was not working if

3023 this code path is really executed because I cannot move to such directory on
3024 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003026- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3027 element is temporarily replaced with an equivalent frozenset. But the
3028 eventual KeyError would always report the empty ``frozenset()`` as the missing

3050 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3051 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3052 of using the replace error handler in PyUnicode_DecodeUTF8().

Georg Brandlba83f822010-03-14 09:50:54 +00004267- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
4268 in the Lib/test directory, which might be read-only for the user running the
4269 tests.

Georg Brandlba83f822010-03-14 09:50:54 +00004283 leak-chasing test runs give sensible results. The previous method of reaping
4284 threads could return successfully while some Thread objects were still
4285 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004286
Georg Brandlba83f822010-03-14 09:50:54 +00004287- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

4292
R. David Murray14dcd432009-10-14 13:58:07 +00004293- Issue #7058: Added save/restore for things like sys.argv and cwd to
4294 runtest_inner in regrtest, with warnings if the called test modifies them,
4295 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004302- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4303 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004304 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4305 the tests if DISPLAY is defined but can't be used.

4311 import both normal and optimised versions of modules. test_heapq and
4312 test_warnings have been adjusted to use it, tests for other modules with both
4313 C and Python implementations in the stdlib can be adjusted to use it over
4314 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004322- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4323 should cause a test to be skipped are now done using import_module from test
4324 support, which does the conversion.

4426
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004427- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4428 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4429 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4430 ``printf`` function, whereas PyString_FromFormat has an independent
4431 implementation and uses "%zd" on all platforms for size_t values.
4432 This makes a difference on win64, where ``printf`` needs "%Id" to display
4433 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004435- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4439 object; previously an int would be returned for small values. the __long__
4440 method is allowed to return either an int or a long, but the behaviour of
4441 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004450 was correctly parsed but parsing of subsequent arguments failed.
4451
Vinay Sajip35e3b032008-09-01 14:33:59 +00004452- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004453 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4454 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4455 when given a tuple of classes as second argument, were looking up
4456 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4457 type object.

4551
Jesse Noller438195f2009-01-18 21:04:36 +00004552- Issue #4301: Patch the logging module to add processName support, remove
4553 _check_logger_class from multiprocessing.
4554
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004555- Issue #2975: When compiling several extension modules with Visual Studio 2008
4556 from the same python interpreter, some environment variables would grow
4557 without limit.
4558
Benjamin Peterson37346b22008-08-23 20:27:43 +00004559- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4560 exploitation of poor argument checking.
4561
Gerhard Häringef2276b2008-09-12 13:54:06 +00004562- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4563
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004564- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4565 remaining ones have "pysqlite_" prefix.
4566
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004567- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00004574- Issue #3781: Add test.test_support.check_warnings() as a convenience
4575 wrapper for warnings.catch_warnings() that makes it easier to check
4576 that expected warning messages are being reported.
4577
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00004578- Issue #3796: Some tests functions were not enabled in test_float.
4579

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004596What's New in Python 2.6 beta 3?
4597================================
4598
Barry Warsaw07a4a382008-08-21 01:15:08 +00004599*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004600
4601Core and Builtins
4602-----------------
4603
Guido van Rossumf8402962008-08-20 15:01:50 +00004604- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4605 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4606 extensions do not automatically benefit from the class attribute
4607 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4608 to their tp_flags field if they care. This is a backwards
4609 compatibility feature; in 3.0, all types will use the cache by
4610 default.
4611
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004612- Keyword arguments can now follow starred arguments. (``f(a, *args,
4613 keyword=23)`` is now valid syntax.)
4614
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004615- ctypes function pointers that are COM methods have a boolean True
4616 value again.
4617
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004618- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4619 by denying s# to parse objects that have a releasebuffer procedure,
4620 and introducing s*.
4621
Georg Brandl1e13ea92008-08-11 09:07:59 +00004622- Issue #3537: Fix an assertion failure when an empty but presized dict
4623 object was stored in the freelist.
4624
Mark Dickinsonb6467572008-08-04 21:30:09 +00004625- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4626 ValueError consistently across platforms.
4627
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004628- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4629 (64bit Unix, for example), unichr() would truncate its argument and return
4630 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4631
Neal Norwitze7d8be82008-07-31 17:17:14 +00004632- Apply security patches from Apple.
4633
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004634- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4635 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4636
Antoine Pitrou92f82162008-07-25 22:22:08 +00004637- Issue #1819: function calls with several named parameters are now on
4638 average 35% faster (as measured by pybench).
4639
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004640- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4641 the python debugger steps into a class statement: the free variables (local
4642 variables defined in an outer scope) would be deleted from the outer scope.
4643
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004644- Issue #2620: Overflow checking when allocating or reallocating memory
4645 was not always being done properly in some python types and extension
4646 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4647 all been updated to perform better checks and places in the code that
4648 would previously leak memory on the error path when such an allocation
4649 failed have been fixed.
4650
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004651Library
4652-------
4653
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004654- Issue #3612: Added some missing basic types in ctypes.wintypes.
4655
Benjamin Petersone977ad42008-08-20 01:42:01 +00004656- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4657 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4658
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004659- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4660 version reported by these tools does not necessarily follow the python
4661 version numbering scheme, so the module is less strict when parsing it.
4662
Nick Coghlanf70385a2008-08-18 12:42:46 +00004663- Issue #2235: Added Py3k warnings for types which will become unhashable
4664 under the stricter __hash__ inheritance rules in 3.0. Several types
4665 which did not meet the rules for hash invariants and were already
4666 unhashable in 3.0 have now been explicitly flagged as unhashable in
4667 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4668 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4669
Brett Cannon88f801d2008-08-18 00:46:22 +00004670- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4671 imported into the module but exposed as part of the module's API.
4672
Brett Cannon7b96f072008-08-18 00:41:11 +00004673- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4674
Brett Cannon46225e72008-08-18 00:36:52 +00004675- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4676
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004677- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4678
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004679- Issue #3575: Incremental decoder's decode function now takes bytearray
4680 by using 's*' instead of 't#'.
4681
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004682- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004683 fails unicode conversion on 2nd parameter. (windows only)
4684
Georg Brandl222e2082010-08-01 22:27:39 +00004685- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004686 in a redirect.
4687
Brett Cannonabe423e2008-08-16 21:47:07 +00004688- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004689 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004690
Facundo Batistaeb90b782008-08-16 14:44:07 +00004691- Issue #2776: fixed small issue when handling an URL with double slash
4692 after a 302 response in the case of not going through a proxy.
4693
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004694- Issue #2676: in the email package, content-type parsing was hanging on
4695 pathological input because of quadratic or exponential behaviour of a
4696 regular expression.
4697
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004698- Issue #3476: binary buffered reading through the new "io" library is now
4699 thread-safe.
4700
Brett Cannonbf3157b2008-08-14 05:00:03 +00004701- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4702 since mimetools itself is deprecated. Because modules are cached, all
4703 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4704
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004705- Issue #3134: shutil referenced undefined WindowsError symbol.
4706
Robert Schuppenies14646332008-08-10 11:01:53 +00004707- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4708 menu entries were not deleted.
4709
Brett Cannon83e81842008-08-09 23:30:55 +00004710- Copied the implementation of reduce() to _functools.reduce() to have a
4711 version that did not raise a DeprecationWarning under -3.
4712
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004713- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4714 a MemoryError rather than silently stop the iteration.
4715
Guido van Rossum59ce9012008-08-09 14:55:34 +00004716- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4717 to _sre.compile() will now be rejected. This should not affect anybody
4718 since the re.compile() function never generates invalid re-bytecode.
4719
Skip Montanaroa032bf42008-08-08 22:52:51 +00004720- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4721 upon first access it can be automatically initialized from the csv file if
4722 it wasn't initialized during instantiation.
4723
Brett Cannon3aa2a492008-08-06 22:28:09 +00004724- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4725 the reload() built-in has been removed.
4726
Brett Cannon7e30b672008-08-04 21:52:25 +00004727- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004728 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004729 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4730 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4731 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4732 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4733 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004734
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004735- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4736 raised an AttributeError.
4737
Benjamin Peterson01a24322008-07-28 23:35:27 +00004738- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004739 asking for a specific length. This problem only affected files opened
4740 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004741
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004742- Issue #3449: Update decimal module to use most recent specification
4743 (v. 1.68) and tests (v. 2.58) from IBM.
4744
Georg Brandl222e2082010-08-01 22:27:39 +00004745- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

4749
Georg Brandlf9efabb2008-07-23 15:16:45 +00004750- Deprecate the "ast" parser function aliases.
4751
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004752- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4753
4754- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4755 invalid arguments.
4756
4757- Issue #3302: Fix several crashes when calling locale's gettext functions
4758 with None arguments.
4759
4760- Issue #3389: Allow resolving dotted names for handlers in logging
4761 configuration files.
4762

4764
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004765- Issue #3394: zipfile.writestr sets external attributes when passed a
4766 file name rather than a ZipInfo instance, so files are extracted with
4767 mode 0600 rather than 000 under Unix.
4768
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004769- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4770 argument in python 2.5, this broke code that subclassed Popen to include its
4771 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4779-------------
4780
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004781- Issue #2235: the C API function PyObject_HashNotImplemented and its
4782 interaction with the tp_hash slot (added in 2.6b2) are now documented
4783
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004784- Issue #643841: The language reference now provides more detailed
4785 coverage of the lookup process for special methods. The disclaimers
4786 regarding lack of coverage of new-style classes have also been
4787 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004790What's New in Python 2.6 beta 2?
4791================================
4792
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004793*Release date: 17-Jul-2008*
4794
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004795Core and Builtins
4796-----------------
4797
Georg Brandl3e483f62008-07-16 22:57:41 +00004798- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4799 its methods now allow for items objects that can be converted to
4800 an integer using operator.index().
4801
Mark Dickinson64b7e502008-07-16 09:40:03 +00004802- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4803 produced a ValueError instead of giving the correct float.
4804
Eric Smitha5fa5a22008-07-16 00:11:49 +00004805- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4806 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4807
Mark Dickinson7103aa42008-07-15 19:08:33 +00004808- Issue #3008: the float type has a new instance method 'float.hex'
4809 and a new class method 'float.fromhex' to convert floating-point
4810 numbers to and from hexadecimal strings, respectively.
4811
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004812- Issue #2235: __hash__ is once again inherited by default. To allow
4813 collections.Hashable to remain meaningful in the presence of the
4814 default hash implementation (object.__hash__), it is now possible
4815 to explicit block inheritance of hash by setting __hash__=None at
4816 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4817 level.
4818
Nick Coghlanb028f502008-07-13 14:52:36 +00004819- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4820 the parent module cannot be found while performing an absolute import.
4821 This means that an incorrectly defined __package__ attribute will
4822 now only prevent relative imports in that module rather than causing
4823 all imports from that module to fail.
4824
Nick Coghlan14ff9942008-07-08 14:21:42 +00004825- Issue #2517: Allow unicode messages in Exceptions again by correctly
4826 bypassing the instance dictionary when looking up __unicode__ on
4827 new-style classes.
4828
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004829- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4830 set to a custom object whose write() method happens to install
4831 another file in sys.stdout.
4832
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004833- Issue #3088: Corrected a race condition in classes derived from
4834 threading.local: the first member set by a thread could be saved in
4835 another thread's dictionary.
4836
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004837- Issue #3004: Minor change to slice.indices(): the start and stop
4838 arguments are now treated identically, making the behaviour easier
4839 to describe and understand. For example, slice(None, -10,
4840 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4841 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00005296 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005297
5298 This is controlled by the configure argument ``--with-universal-archs``:
5299
5300 - ``--with-universal-archs=all``: install 4-way universal
5301
5302 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5303
5304 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5305
5306 This option should be used in combination with ``--enable-universalsdk=``.

5345 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005358- Issue #1631171: Re-implement the 'warnings' module in C (the
5359 original Python code has been kept as backup). This will allow for
5360 using the 'warning's machinery in such places as the parser where
5361 use of pure Python code is not possible. Both the ``showarning()``
5362 and ``formatwarning()`` gain an optional 'line' argument which is
5363 not called by default for backwards-compatibility reasons. Setting
5364 ``warnings.showwarning()`` to an implementation that lacks support
5365 for the ``line`` argument will raise a DeprecationWarning.

5389
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005390- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00005428- Issue #2550: The approach used by client/server code for obtaining
5429 ports to listen on in network-oriented tests has been refined in an
5430 effort to facilitate running multiple instances of the entire
5431 regression test suite in parallel without issue.
5432 test_support.bind_port() has been fixed such that it will always
5433 return a unique port -- which wasn't always the case with the
5434 previous implementation, especially if socket options had been set
5435 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5436 new implementation of bind_port() will actually raise an exception
5437 if it is passed an AF_INET/SOCK_STREAM socket with either the
5438 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5439 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5440 the socket it's been passed. This currently only applies to
5441 Windows. This option prevents any other sockets from binding to the
5442 host/port we've bound to, thus removing the possibility of the
5443 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5444 when a second SOCK_STREAM socket binds and accepts to a host/port
5445 that's already been bound by another socket. The optional preferred
5446 port parameter to bind_port() has been removed. Under no
5447 circumstances should tests be hard coding ports!
5448
5449 test_support.find_unused_port() has also been introduced, which will
5450 pass a temporary socket object to bind_port() in order to obtain an
5451 unused port. The temporary socket object is then closed and
5452 deleted, and the port is returned. This method should only be used
5453 for obtaining an unused port in order to pass to an external program
5454 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5455 a parameter to a server-oriented class that doesn't give you direct
5456 access to the underlying socket used.
5457
5458 Finally, test_support.HOST has been introduced, which should be used
5459 for the host argument of any relevant socket calls (i.e. bind and
5460 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005461
5462 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005463 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005464 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5465 test_asynchat and test_socket_ssl.
5466
Georg Brandl3ee81df2008-05-17 18:14:43 +00005467 It is now possible for multiple instances of the regression test
5468 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005747- Added the future_builtins module, which contains hex() and oct().
5748 These are the PEP 3127 version of these functions, designed to be
5749 compatible with the hex() and oct() builtins from Python 3.0. They
5750 differ slightly in their output formats from the existing, unchanged
5751 Python 2.6 builtins. The expected usage of the future_builtins
5752 module is:
5753 from future_builtins import hex, oct
5754
Eric Smith7ef40bf2008-02-20 23:34:22 +00005755- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5756 exponents for exponents with absolute value < 100. Follows C99
5757 standard. This is a change on Windows, which would use 3 digits.
5758 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5759 so that any alterations it does to the resulting string will be
5760 available in stringlib/formatter.h (for float.__format__).
5761
Eric Smith5a3c1352008-02-19 13:21:56 +00005762- Implemented PEP 3101, Advanced String Formatting. This adds a new
5763 builtin format(); a format() method for str and unicode; a
5764 __format__() method to object, str, unicode, int, long, float, and
5765 datetime; the class string.Formatter; and the C API
5766 PyObject_Format().
5767
Georg Brandl3ee81df2008-05-17 18:14:43 +00005768- Fixed several potential crashes, all caused by specially crafted
5769 __del__ methods exploiting objects in temporarily inconsistent
5770 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005771
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005772- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005773 prevent a possible crash: an Abstract Base Class would try to access
5774 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005775

Georg Brandl3ee81df2008-05-17 18:14:43 +00005779- Clear all free lists during a gc.collect() of the highest generation
5780 in order to allow pymalloc to free more arenas. Python may give back
5781 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005782
Georg Brandl3ee81df2008-05-17 18:14:43 +00005783- Issue #2045: Fix an infinite recursion triggered when printing a
5784 subclass of collections.defaultdict, if its default_factory is set
5785 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005786
Christian Heimesf75dbef2008-02-08 00:11:31 +00005787- Fixed a minor memory leak in dictobject.c. The content of the free
5788 list was not freed on interpreter shutdown.
5789
Georg Brandl21e99f42010-03-07 15:23:59 +00005790- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005791 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005792
Georg Brandl3ee81df2008-05-17 18:14:43 +00005793- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5794 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005795 to compact the internal free lists of pre-allocted ints and floats.
5796
Georg Brandl3ee81df2008-05-17 18:14:43 +00005797- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5798 calls. Python expected the return type int but the fork familie
5799 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005800
Georg Brandl3ee81df2008-05-17 18:14:43 +00005801- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5802 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005803

5811 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00005812
Georg Brandl3ee81df2008-05-17 18:14:43 +00005813- Patch #1473257: generator objects gain a gi_code attribute. This is
5814 the same object as the func_code attribute of the function that
5815 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005816
Georg Brandl3ee81df2008-05-17 18:14:43 +00005817- Issue #1920: "while 0" statements were completely removed by the
5818 compiler, even in the presence of an "else" clause, which is
5819 supposed to be run when the condition is false. Now the compiler
5820 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005821
Guido van Rossumeead05f2008-01-24 18:21:02 +00005822- A few crashers fixed: weakref_in_del.py (issue #1377858);
5823 loosing_dict_ref.py (issue #1303614, test67.py);
5824 borrowed_ref_[34].py (not in tracker).
5825
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005826- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005827 suppressed while an extension is loaded by calling SetErrorMode in
5828 dynload_win.c. The error is still reported properly.
5829
Georg Brandl3ee81df2008-05-17 18:14:43 +00005830- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005831 several extension methods and modules do not work without unicode
5832 support.
5833
Georg Brandl26543b12008-01-21 18:36:51 +00005834- Issue #1882: when compiling code from a string, encoding cookies in the
5835 second line of code were not always recognized correctly.
5836
Georg Brandl14404b62008-01-19 19:27:05 +00005837- Issue #1679: "0x" was taken as a valid integer literal.
5838
Georg Brandl6caad7d2008-01-26 14:19:22 +00005839- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005840 added.
5841
Christian Heimesc94e2b52008-01-14 04:13:37 +00005842- sys.float_info / PyFloat_GetInfo: The floating point information
5843 object was converted from a dict to a specialized structseq object.
5844
Georg Brandl3ee81df2008-05-17 18:14:43 +00005845- Patch #1816: Added sys.flags structseq. It exposes the status of
5846 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005847
Georg Brandl3ee81df2008-05-17 18:14:43 +00005848- Objects/structseq.c: Implemented new structseq representation. The
5849 patch makes structseqs (e.g. the return value of os.stat) more
5850 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005851
Georg Brandl3ee81df2008-05-17 18:14:43 +00005852- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005909- Patch #1739468: Directories and zipfiles containing a __main__.py
5910 file can now be directly executed by passing their name to the
5911 interpreter. The directory/zipfile is automatically inserted as the
5912 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005914- Issue #1265: Fix a problem with sys.settrace, if the tracing
5915 function uses a generator expression when at the same time the
5916 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005917
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005918- sets and frozensets now have an isdisjoint() method.

5923
Georg Brandl21e99f42010-03-07 15:23:59 +00005924- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005925 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5926 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005927
Georg Brandl3ee81df2008-05-17 18:14:43 +00005928- Issue #1686386: Tuple's tp_repr did not take into account the
5929 possibility of having a self-referential tuple, which is possible
5930 from C code. Nor did object's tp_str consider that a type's tp_str
5931 could do something that could lead to an inifinite recursion.
5932 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5933 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005934
Georg Brandl3ee81df2008-05-17 18:14:43 +00005935- Issue #1164: It was possible to trigger deadlock when using the
5936 'print' statement to write to a file since the GIL was not released
5937 as needed. Now PyObject_Print() does the right thing along with
5938 various tp_print implementations of the built-in types and those in
5939 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005940
Georg Brandl3ee81df2008-05-17 18:14:43 +00005941- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00005948- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005949 PyObject_Call() never calling back out to Python code to trigger
5950 recursion depth updates/checks. Required the creation of a static
5951 RuntimeError instance in case normalizing an exception put the
5952 recursion check value past its limit. Fixes crashers
5953 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005968- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005969 __*__ attributes. (Some already existed, e.g., __doc__ and
5970 __name__.)

Georg Brandl2134e752007-05-21 20:34:16 +00005975- Patch #1686487: you can now pass any mapping after '**' in function
5976 calls.
5977
Collin Winter62903052007-05-18 23:11:24 +00005978- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005979 "except E as target:". This is to provide forwards compatibility
5980 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005987- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005988 setting a plain string, ie don't expand to single letter identifiers.
5989
Raymond Hettinger13936692007-04-11 18:40:58 +00005990- Request #1191699: Slices can now be pickled.
5991
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005992- Request #1193128: str.translate() now allows a None argument for

5994 remaining characters.
5995
Georg Brandl5cb76c12007-03-21 09:00:39 +00005996- Patch #1682205: a TypeError while unpacking an iterable is no longer

6000
Guido van Rossum143b5642007-03-23 04:58:42 +00006001- Bug #1683368: The object.__init__() and object.__new__() methods are
6002 now stricter in rejecting excess arguments. The only time when
6003 either allows excess arguments is when it is not overridden and the
6004 other one is. For backwards compatibility, when both are
6005 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006006 warning later). Also, type.__init__() insists on the same signature
6007 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006008
Georg Brandl3ee81df2008-05-17 18:14:43 +00006009- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6010 object to complex using its __complex__() method before falling back
6011 to the __float__() method. Therefore, the functions in the cmath
6012 module now can operate on objects that define a __complex__()
6013 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006014
Georg Brandl3ee81df2008-05-17 18:14:43 +00006015- Patch #1623563: allow __class__ assignment for classes with

6017 same slot names.

6024 its type.

6030
Georg Brandl7b9c5552007-03-12 14:30:05 +00006031- Bug #1678647: write a newline after printing an exception in any
6032 case, even when converting the value to a string failed.
6033
Georg Brandl871f1bc2007-03-12 13:17:36 +00006034- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006035 its argument, if it exists. If not, it will work like before. This
6036 allows customizing the output of dir() in the presence of a
6037 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006045- Patch #1491866: change the complex() constructor to allow
6046 parthensized forms. This means complex(repr(x)) now works instead of
6047 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006048
Georg Brandlaa2321b2007-03-07 00:40:28 +00006049- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006050 makes the filenames the warning module prints much more sensible
6051 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006064- Patch #1674228: when assigning a slice (old-style), check for the
6065 sq_ass_slice instead of the sq_slice slot.
6066
Georg Brandl3ee81df2008-05-17 18:14:43 +00006067- When printing an unraisable error, don't print exceptions. before
6068 the name. This duplicates the behavior whening normally printing
6069 exceptions.

6635
Georg Brandl92a6bae2007-03-13 17:43:32 +00006636- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006637 are set for invalid interpolation sequences that would lead to

6694 TestCase and TestSuite subclasses (not instances) are no longer
6695 accepted in TestSuite.addTest(). This should cause no
6696 incompatibility since it never made sense with ordinary subclasses
6697 -- the failure just occurred later, with a more cumbersome
6698 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006979- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6980 with RFC 3207 and forgets any knowledge obtained from the server not
6981 obtained from the TLS negotiation itself. Patch contributed by Bill
6982 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006983
Georg Brandl3ee81df2008-05-17 18:14:43 +00006984- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006985 that the SMTP.starttls() caller no longer needs to call ehlo()
6986 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006987 does not claim to support starttls. Adds the
6988 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00007043- itertools.chain() now has an alternate constructor,

7069 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7070 silently miscode subclasses of those types. Now, it raises a
7071 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007072

Georg Brandl3ee81df2008-05-17 18:14:43 +00007087 time so that opening a database previously created with the DB_DUP
7088 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7089 opens. Specifically: dictionary assignment to a DB object will
7090 replace all values for a given key when the database allows
7091 duplicate values. DB users should use DB.put(k, v) when they want
7092 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007093

7099 characters with ASCII value less than 32. Also, it correctly quotes
7100 dots only if they occur on a single line, as opposed to the previous
7101 behavior of quoting dots if they are the second character of any
7102 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007103

Guido van Rossum7c862f82007-12-13 20:50:10 +00007365- Bug #1608: use -fwrapv when GCC supports it. This is important,
7366 newer GCC versions may optimize away overflow buffer overflow checks
7367 without this option!
7368
Martin v. Löwis63bf1492007-11-12 05:14:05 +00007369- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
7370
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007371- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007372 periodic threadstate and signal checking in tight loops. By
7373 default, this option is turned-off. It should only be enabled in
7374 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007375

7390 returned by python-config if Python was built with --enable-shared
7391 because that prevented the shared library from being used.
7392

7425-----
7426
Georg Brandl3ee81df2008-05-17 18:14:43 +00007427- Unified naming convention for free lists and their limits. All free
7428 lists in Object/ are named ``free_list``, the counter ``numfree``
7429 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7430 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007431
Georg Brandl3ee81df2008-05-17 18:14:43 +00007432- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7433 to ``PyTuple_SetItem``, it can be used to populate a brand new
7434 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007435
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007436- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

7442- Patch #1720595: add T_BOOL to the range of structmember types.
7443
7444- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7445 ``PyFloat_GetInfo()`` to the float API.
7446
Georg Brandl3ee81df2008-05-17 18:14:43 +00007447- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7448 of w# format code incorrectly truncated the length to an int, even
7449 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7450 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007451
Georg Brandl3ee81df2008-05-17 18:14:43 +00007452- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7470- Fix some leftovers from the conversion from int to Py_ssize_t
7471 (relevant to strings and sequences of more than 2**31 items).
7472
7473- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7474 outside of pystate.c and should not be necessary.
7475
Georg Brandl3ee81df2008-05-17 18:14:43 +00007476- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7477 absolute imports. In earlier versions they might have used relative
7478 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007479
Georg Brandl3ee81df2008-05-17 18:14:43 +00007480- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7481 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007482
Georg Brandl3ee81df2008-05-17 18:14:43 +00007483- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00007490- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7491 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7492 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7493 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007494

Georg Brandl3ee81df2008-05-17 18:14:43 +00007508- Removed the macfs module. It had been deprecated since Python 2.5.
7509 This lead to the deprecation of macostools.touched() as it relied
7510 solely on macfs and was a no-op under OS X.
