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
25 Python 3.1. callable() is again supported in Python 3.2.
26
Victor Stinner59729ff2011-07-05 11:28:19 +020027- Issue #9611, #9015: FileIO.read(), FileIO.readinto(), FileIO.write() and
28 os.write() clamp the length to INT_MAX on Windows.
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

45 directory, so that "import DLFCN" and other similar imports work on
46 Linux 3.0.
47
R David Murray95225952011-07-18 21:34:04 -040048- Issue #7484: smtplib no longer puts <> around addresses in VRFY and EXPN
49 commands; they aren't required and in fact postfix doesn't support that form.
50
Antoine Pitrou304f0f92011-07-15 21:22:50 +020051- Issue #11603: Fix a crash when __str__ is rebound as __repr__. Patch by
52 Andreas Stührk.
53
Charles-François Natali26591402011-07-14 19:49:02 +020054- Issue #12502: asyncore: fix polling loop with AF_UNIX sockets.
55

66 the garbage collector while the Heap lock is held.
67
Ned Deily87e82bb2011-06-28 19:52:59 -070068- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
69 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
70 interpreter process. This could cause failures in non-Distutils subprocesses
71 and was unreliable since tests or user programs could modify the interpreter
72 environment after Distutils set it. Instead, have Distutils set the the
73 deployment target only in the environment of each build subprocess. It is
74 still possible to globally override the default by setting
75 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
76 greater or equal to the default value, the value with which the interpreter
77 was built.
78
Raymond Hettinger2c316a32011-06-25 17:14:53 +020079- Issue #11802: The cache in filecmp now has a maximum size of 100 so that

83 Kitada.
84
R David Murrayf1138bb2011-06-17 22:23:04 -040085- Issue #11700: mailbox proxy object close methods can now be called multiple
86 times without error, and _ProxyFile now closes the wrapped file.
87
Victor Stinnerc74a6ba2011-06-17 14:06:27 +020088- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
89 connection if its getresponse() method fails with a socket error. Patch
90 written by Ezio Melotti.
91
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -050092- Issue #9284: Allow inspect.findsource() to find the source of doctest
93 functions.
94
R David Murray873c5832011-06-09 16:01:09 -040095- Issue #10694: zipfile now ignores garbage at the end of a zipfile.
96
Brian Curtincaea7e82011-06-08 19:29:53 -050097- Issue #11583: Speed up os.path.isdir on Windows by using GetFileAttributes
98 instead of os.stat.
99
Mark Dickinsona493ca32011-06-04 18:24:15 +0100100- Issue #12080: Fix a performance issue in Decimal._power_exact that caused
101 some corner-case Decimal.__pow__ calls to take an unreasonably long time.

Raymond Hettinger45b08292011-06-02 20:40:35 -0700103- Named tuples now work correctly with vars().
104
Barry Warsawc5643282011-07-19 17:06:30 -0400105- sys.setcheckinterval() now updates the current ticker count as well as
106 updating the check interval, so if the user decreases the check interval,
107 the ticker doesn't have to wind down to zero from the old starting point
108 before the new interval takes effect. And if the user increases the
109 interval, it makes sure the new limit takes effect right away rather have an
110 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700111
Victor Stinner776e69b2011-06-01 01:03:00 +0200112- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

135 as the processor type on some Mac systems.
136
Antoine Pitrou4a4a0fe2011-07-09 02:34:05 +0200137- Skip network tests when getaddrinfo() returns EAI_AGAIN, meaning a temporary

149 test_tk or test_ttk_guionly under a username that is not currently logged
150 in to the console windowserver (as may be the case under buildbot or ssh).
151
Ned Deily63144c62011-06-28 00:39:19 -0700152- Issue #12141: Install a copy of template C module file so that

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

990 character years even if the message contains RFC822 two character years.
991
Daniel Stutzbach91287322010-08-24 21:09:30 +0000992- Issue #8750: Fixed MutableSet's methods to correctly handle

1026 when the underlying raw IO channel was e.g. a socket. Report and original
1027 patch by Jason V. Miller.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001417- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1418 start byte and the continuation byte(s) are now considered invalid, instead
1419 of the number of bytes specified by the start byte.
1420 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1421 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1432 objects. (1) The comparison could incorrectly return True in some cases
1433 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1434 (2) The comparison raised an OverflowError for large integers, leading

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00001778 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
1779 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
1780 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

1800Core and Builtins
1801-----------------
1802
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001803- Issue #7301: Add environment variable $PYTHONWARNINGS.
1804
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001805- Issue #8329: Don't return the same lists from select.select when no fds are
1806 changed.
1807
Georg Brandlfee0f442010-05-22 21:26:21 +00001808- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001809 on 64-bit machines. The shift count for either left or right shift is
1810 permitted to be up to sys.maxsize.
1811
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00001812- Ensure that tokenization of identifiers is not affected by locale.
1813
Georg Brandlfee0f442010-05-22 21:26:21 +00001814- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00001815
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00001816- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
1817
Georg Brandlfee0f442010-05-22 21:26:21 +00001818- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1819 with a non-empty format string. This is an effort to future-proof user
1820 code. If a derived class does not currently implement __format__ but later
1821 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001822 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001823 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00001824
Antoine Pitroua57df2c2010-03-31 21:32:15 +00001825- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00001838- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00001839 (SIGINT). If an error occurs while importing the site module, the error is

1855
Georg Brandlfee0f442010-05-22 21:26:21 +00001856- Issue #8257: The Decimal construct now accepts a float instance directly,
1857 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001858
1859 >>> Decimal(1.1)
1860 Decimal('1.100000000000000088817841970012523233890533447265625')
1861
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001862- collections.Counter() now supports a subtract() method.
1863
Georg Brandlfee0f442010-05-22 21:26:21 +00001864- The functools module now has a total_ordering() class decorator to simplify
1865 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001866
Georg Brandlfee0f442010-05-22 21:26:21 +00001867- The functools module also adds cmp_to_key() as a tool to transition old-style
1868 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001869
Georg Brandlfee0f442010-05-22 21:26:21 +00001870- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1871 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001872
Georg Brandlfee0f442010-05-22 21:26:21 +00001873- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1874 InvalidOperation instead of returning False. (Comparisons involving a quiet
1875 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1876 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001877
Georg Brandlfee0f442010-05-22 21:26:21 +00001878- Issue #2531: Comparison operations between floats and Decimal instances now
1879 return a result based on the numeric values of the operands; previously they
1880 returned an arbitrary result based on the relative ordering of id(float) and
1881 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001882
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001883- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001884 argument `-` which tells it to read files to compile from stdin. Each line is
1885 read on demand and the named file is compiled immediately. (Original patch by
1886 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00001891- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1892 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001893 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001894
Georg Brandlfee0f442010-05-22 21:26:21 +00001895- Comparisons using one of <, <=, >, >= between a complex instance and a
1896 Fractions instance now raise TypeError instead of returning True/False. This
1897 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1898 <=> complex, and complex <=> complex comparisons.

2003 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2004 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002005 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2006 inconsistent: __int__ was used for some integer codes but not for others, and
2007 the set of integer codes for which it was used differed between native packing
2008 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002255- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2256 and add the additional members returned in an OSVERSIONINFOEX structure. The
2257 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002260- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2261 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2262 returning NULL. The macro now returns a statically allocated empty string
2263 instead.

2273 strings,
2274 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2275 numeric strings corresponding to subnormal values,

Antoine Pitroud840e512010-02-04 20:20:18 +00002308- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002309 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002310 Also, raise ValueError rather than TypeError when an unknown TIPC address
2311 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002315- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002316 file position when calling `truncate()`. It would previously change the file
2317 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002318 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2319
Georg Brandlba83f822010-03-14 09:50:54 +00002320- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2321 class used to represent files stored inside an archive. The new
2322 implementation is significantly faster and can be wrapped in a
2323 ``io.BufferedReader`` object for more speedups. It also solves an issue
2324 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2325 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00002334
Georg Brandlba83f822010-03-14 09:50:54 +00002335- Issue #7748: Since unicode values are supported for some metadata options in
2336 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2337 encoded string for them. This ensures that the upload and register commands
2338 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002609- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2610 decimal string that's guaranteed to round back to x under correct rounding
2611 (with round-half-to-even rounding mode). Previously it gave a string based on
2612 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2613 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2614 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002615
Georg Brandlba83f822010-03-14 09:50:54 +00002616- Issue #7117: On almost all platforms: float-to-string and string-to-float
2617 conversions within Python are now correctly rounded. Places these conversions
2618 occur include: str for floats and complex numbers; the float and complex
2619 constructors; old-style and new-style numeric formatting; serialization and
2620 deserialization of floats and complex numbers using marshal, pickle and json;
2621 parsing of float and imaginary literals in Python code; Decimal-to-float
2622 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002623
Georg Brandlba83f822010-03-14 09:50:54 +00002624 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2625 providing correctly-rounded strtod and dtoa C functions. This code is
2626 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2627 the C compiler. There may be a small number of platforms on which correct
2628 operation of this code cannot be guaranteed, so the code is not used: notably,
2629 this applies to platforms where the C double format is not IEEE 754 binary64,
2630 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2631 and Python's configure script is unable to determine how to change the FPU
2632 precision. On these platforms conversions use the platform strtod and dtoa,
2633 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002635- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2636 uses the correctly-rounded string <-> float conversions described above (when
2637 available), and so produces correctly rounded results that will display nicely
2638 under the float repr. There are two related small changes: (1) round now
2639 accepts any class with an ``__index__()`` method for its second argument (but
2640 no longer accepts floats for the second argument), and (2) an excessively
2641 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2642 raises an exception.

2791 but with at least one decimal point and with a default precision
2792 of 12. Previously, the behavior the same but with a default precision of 6.
2793 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandl29c6a282009-04-05 20:23:13 +00002904- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002905 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00002935- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2936 existing .py counterpart, override the co_filename attributes of all code
2937 objects if the original filename is obsolete (which can happen if the file has

2985 instead of throwing a MemoryError.
2986
Georg Brandlba83f822010-03-14 09:50:54 +00002987- Issue #3689: The list reversed iterator now supports __length_hint__ instead

2992
Georg Brandlba83f822010-03-14 09:50:54 +00002993- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2994 file objects with closefd=False. The file descriptor is still kept open but
2995 the file object behaves like a closed file. The ``FileIO`` object also got a
2996 new readonly attribute ``closefd``.

3015
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003016- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003017 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00003019- On windows, ``os.chdir()`` given unicode was not working if
3020 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3021 this code path is really executed because I cannot move to such directory on
3022 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003024- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3025 element is temporarily replaced with an equivalent frozenset. But the
3026 eventual KeyError would always report the empty ``frozenset()`` as the missing
3027 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003047- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3048 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3049 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3050 of using the replace error handler in PyUnicode_DecodeUTF8().
3051
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003052- Issue #3739: The unicode-internal encoder now reports the number of characters

3054
Georg Brandlba83f822010-03-14 09:50:54 +00003055- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3056 allocator will be automatically disabled when running under Valgrind. This
3057 gives improved memory leak detection when running under Valgrind, while taking
3058 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004265- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
4266 in the Lib/test directory, which might be read-only for the user running the
4267 tests.

Georg Brandlba83f822010-03-14 09:50:54 +00004281 leak-chasing test runs give sensible results. The previous method of reaping
4282 threads could return successfully while some Thread objects were still
4283 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004284
Georg Brandlba83f822010-03-14 09:50:54 +00004285- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

R. David Murray14dcd432009-10-14 13:58:07 +00004291- Issue #7058: Added save/restore for things like sys.argv and cwd to
4292 runtest_inner in regrtest, with warnings if the called test modifies them,
4293 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004300- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4301 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004302 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4303 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00004308- Issue #5354: New test support function import_fresh_module() makes it easy to
4309 import both normal and optimised versions of modules. test_heapq and
4310 test_warnings have been adjusted to use it, tests for other modules with both
4311 C and Python implementations in the stdlib can be adjusted to use it over
4312 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004320- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4321 should cause a test to be skipped are now done using import_module from test
4322 support, which does the conversion.

4424
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004425- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4426 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4427 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4428 ``printf`` function, whereas PyString_FromFormat has an independent
4429 implementation and uses "%zd" on all platforms for size_t values.
4430 This makes a difference on win64, where ``printf`` needs "%Id" to display
4431 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004433- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4437 object; previously an int would be returned for small values. the __long__
4438 method is allowed to return either an int or a long, but the behaviour of
4439 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004448 was correctly parsed but parsing of subsequent arguments failed.
4449
Vinay Sajip35e3b032008-09-01 14:33:59 +00004450- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004451 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4452 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4453 when given a tuple of classes as second argument, were looking up
4454 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4455 type object.

4549
Jesse Noller438195f2009-01-18 21:04:36 +00004550- Issue #4301: Patch the logging module to add processName support, remove
4551 _check_logger_class from multiprocessing.
4552
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004553- Issue #2975: When compiling several extension modules with Visual Studio 2008
4554 from the same python interpreter, some environment variables would grow
4555 without limit.
4556
Benjamin Peterson37346b22008-08-23 20:27:43 +00004557- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4558 exploitation of poor argument checking.
4559
Gerhard Häringef2276b2008-09-12 13:54:06 +00004560- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4561
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004562- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4563 remaining ones have "pysqlite_" prefix.
4564
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004565- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00004572- Issue #3781: Add test.test_support.check_warnings() as a convenience
4573 wrapper for warnings.catch_warnings() that makes it easier to check
4574 that expected warning messages are being reported.
4575
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00004576- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004594What's New in Python 2.6 beta 3?
4595================================
4596
Barry Warsaw07a4a382008-08-21 01:15:08 +00004597*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004598
4599Core and Builtins
4600-----------------
4601
Guido van Rossumf8402962008-08-20 15:01:50 +00004602- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4603 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4604 extensions do not automatically benefit from the class attribute
4605 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4606 to their tp_flags field if they care. This is a backwards
4607 compatibility feature; in 3.0, all types will use the cache by
4608 default.
4609
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004610- Keyword arguments can now follow starred arguments. (``f(a, *args,
4611 keyword=23)`` is now valid syntax.)
4612
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004613- ctypes function pointers that are COM methods have a boolean True
4614 value again.
4615
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004616- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4617 by denying s# to parse objects that have a releasebuffer procedure,
4618 and introducing s*.
4619
Georg Brandl1e13ea92008-08-11 09:07:59 +00004620- Issue #3537: Fix an assertion failure when an empty but presized dict
4621 object was stored in the freelist.
4622
Mark Dickinsonb6467572008-08-04 21:30:09 +00004623- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4624 ValueError consistently across platforms.
4625
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004626- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4627 (64bit Unix, for example), unichr() would truncate its argument and return
4628 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4629
Neal Norwitze7d8be82008-07-31 17:17:14 +00004630- Apply security patches from Apple.
4631
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004632- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4633 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4634
Antoine Pitrou92f82162008-07-25 22:22:08 +00004635- Issue #1819: function calls with several named parameters are now on
4636 average 35% faster (as measured by pybench).
4637
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004638- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4639 the python debugger steps into a class statement: the free variables (local
4640 variables defined in an outer scope) would be deleted from the outer scope.
4641
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004642- Issue #2620: Overflow checking when allocating or reallocating memory
4643 was not always being done properly in some python types and extension
4644 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4645 all been updated to perform better checks and places in the code that
4646 would previously leak memory on the error path when such an allocation
4647 failed have been fixed.
4648
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004649Library
4650-------
4651
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004652- Issue #3612: Added some missing basic types in ctypes.wintypes.
4653
Benjamin Petersone977ad42008-08-20 01:42:01 +00004654- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4655 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4656
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004657- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4658 version reported by these tools does not necessarily follow the python
4659 version numbering scheme, so the module is less strict when parsing it.
4660
Nick Coghlanf70385a2008-08-18 12:42:46 +00004661- Issue #2235: Added Py3k warnings for types which will become unhashable
4662 under the stricter __hash__ inheritance rules in 3.0. Several types
4663 which did not meet the rules for hash invariants and were already
4664 unhashable in 3.0 have now been explicitly flagged as unhashable in
4665 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4666 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4667
Brett Cannon88f801d2008-08-18 00:46:22 +00004668- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4669 imported into the module but exposed as part of the module's API.
4670
Brett Cannon7b96f072008-08-18 00:41:11 +00004671- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4672
Brett Cannon46225e72008-08-18 00:36:52 +00004673- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4674
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004675- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4676
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004677- Issue #3575: Incremental decoder's decode function now takes bytearray
4678 by using 's*' instead of 't#'.
4679
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004680- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004681 fails unicode conversion on 2nd parameter. (windows only)
4682
Georg Brandl222e2082010-08-01 22:27:39 +00004683- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004684 in a redirect.
4685
Brett Cannonabe423e2008-08-16 21:47:07 +00004686- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004687 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004688
Facundo Batistaeb90b782008-08-16 14:44:07 +00004689- Issue #2776: fixed small issue when handling an URL with double slash
4690 after a 302 response in the case of not going through a proxy.
4691
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004692- Issue #2676: in the email package, content-type parsing was hanging on
4693 pathological input because of quadratic or exponential behaviour of a
4694 regular expression.
4695
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004696- Issue #3476: binary buffered reading through the new "io" library is now
4697 thread-safe.
4698
Brett Cannonbf3157b2008-08-14 05:00:03 +00004699- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4700 since mimetools itself is deprecated. Because modules are cached, all
4701 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4702
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004703- Issue #3134: shutil referenced undefined WindowsError symbol.
4704
Robert Schuppenies14646332008-08-10 11:01:53 +00004705- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4706 menu entries were not deleted.
4707
Brett Cannon83e81842008-08-09 23:30:55 +00004708- Copied the implementation of reduce() to _functools.reduce() to have a
4709 version that did not raise a DeprecationWarning under -3.
4710
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004711- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4712 a MemoryError rather than silently stop the iteration.
4713
Guido van Rossum59ce9012008-08-09 14:55:34 +00004714- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4715 to _sre.compile() will now be rejected. This should not affect anybody
4716 since the re.compile() function never generates invalid re-bytecode.
4717
Skip Montanaroa032bf42008-08-08 22:52:51 +00004718- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4719 upon first access it can be automatically initialized from the csv file if
4720 it wasn't initialized during instantiation.
4721
Brett Cannon3aa2a492008-08-06 22:28:09 +00004722- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4723 the reload() built-in has been removed.
4724
Brett Cannon7e30b672008-08-04 21:52:25 +00004725- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004726 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004727 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4728 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4729 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4730 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4731 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004732
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004733- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4734 raised an AttributeError.
4735
Benjamin Peterson01a24322008-07-28 23:35:27 +00004736- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004737 asking for a specific length. This problem only affected files opened
4738 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004739
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004740- Issue #3449: Update decimal module to use most recent specification
4741 (v. 1.68) and tests (v. 2.58) from IBM.
4742
Georg Brandl222e2082010-08-01 22:27:39 +00004743- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

4747
Georg Brandlf9efabb2008-07-23 15:16:45 +00004748- Deprecate the "ast" parser function aliases.
4749
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004750- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4751
4752- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4753 invalid arguments.
4754
4755- Issue #3302: Fix several crashes when calling locale's gettext functions
4756 with None arguments.
4757
4758- Issue #3389: Allow resolving dotted names for handlers in logging
4759 configuration files.
4760

4762
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004763- Issue #3394: zipfile.writestr sets external attributes when passed a
4764 file name rather than a ZipInfo instance, so files are extracted with
4765 mode 0600 rather than 000 under Unix.
4766
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004767- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4768 argument in python 2.5, this broke code that subclassed Popen to include its
4769 own poll method. Fixed my moving _deadstate to an _internal_poll method.

4777-------------
4778
Nick Coghlan6e8fef02008-08-18 13:14:22 +00004779- Issue #2235: the C API function PyObject_HashNotImplemented and its
4780 interaction with the tp_hash slot (added in 2.6b2) are now documented
4781
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004782- Issue #643841: The language reference now provides more detailed
4783 coverage of the lookup process for special methods. The disclaimers
4784 regarding lack of coverage of new-style classes have also been
4785 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004788What's New in Python 2.6 beta 2?
4789================================
4790
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004791*Release date: 17-Jul-2008*
4792
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004793Core and Builtins
4794-----------------
4795
Georg Brandl3e483f62008-07-16 22:57:41 +00004796- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4797 its methods now allow for items objects that can be converted to
4798 an integer using operator.index().
4799
Mark Dickinson64b7e502008-07-16 09:40:03 +00004800- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4801 produced a ValueError instead of giving the correct float.
4802
Eric Smitha5fa5a22008-07-16 00:11:49 +00004803- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4804 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4805
Mark Dickinson7103aa42008-07-15 19:08:33 +00004806- Issue #3008: the float type has a new instance method 'float.hex'
4807 and a new class method 'float.fromhex' to convert floating-point
4808 numbers to and from hexadecimal strings, respectively.
4809
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004810- Issue #2235: __hash__ is once again inherited by default. To allow
4811 collections.Hashable to remain meaningful in the presence of the
4812 default hash implementation (object.__hash__), it is now possible
4813 to explicit block inheritance of hash by setting __hash__=None at
4814 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4815 level.
4816
Nick Coghlanb028f502008-07-13 14:52:36 +00004817- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4818 the parent module cannot be found while performing an absolute import.
4819 This means that an incorrectly defined __package__ attribute will
4820 now only prevent relative imports in that module rather than causing
4821 all imports from that module to fail.
4822
Nick Coghlan14ff9942008-07-08 14:21:42 +00004823- Issue #2517: Allow unicode messages in Exceptions again by correctly
4824 bypassing the instance dictionary when looking up __unicode__ on
4825 new-style classes.
4826
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004827- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4828 set to a custom object whose write() method happens to install
4829 another file in sys.stdout.
4830
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004831- Issue #3088: Corrected a race condition in classes derived from
4832 threading.local: the first member set by a thread could be saved in
4833 another thread's dictionary.
4834
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004835- Issue #3004: Minor change to slice.indices(): the start and stop
4836 arguments are now treated identically, making the behaviour easier
4837 to describe and understand. For example, slice(None, -10,
4838 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4839 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

5293 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005294 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005295
5296 This is controlled by the configure argument ``--with-universal-archs``:
5297
5298 - ``--with-universal-archs=all``: install 4-way universal
5299
5300 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5301
5302 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5303
5304 This option should be used in combination with ``--enable-universalsdk=``.

5343 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005344
Christian Heimese74c8f22008-04-19 02:23:57 +00005345- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5346

Georg Brandl3ee81df2008-05-17 18:14:43 +00005356- Issue #1631171: Re-implement the 'warnings' module in C (the
5357 original Python code has been kept as backup). This will allow for
5358 using the 'warning's machinery in such places as the parser where
5359 use of pure Python code is not possible. Both the ``showarning()``
5360 and ``formatwarning()`` gain an optional 'line' argument which is
5361 not called by default for backwards-compatibility reasons. Setting
5362 ``warnings.showwarning()`` to an implementation that lacks support
5363 for the ``line`` argument will raise a DeprecationWarning.

5387
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005388- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00005426- Issue #2550: The approach used by client/server code for obtaining
5427 ports to listen on in network-oriented tests has been refined in an
5428 effort to facilitate running multiple instances of the entire
5429 regression test suite in parallel without issue.
5430 test_support.bind_port() has been fixed such that it will always
5431 return a unique port -- which wasn't always the case with the
5432 previous implementation, especially if socket options had been set
5433 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5434 new implementation of bind_port() will actually raise an exception
5435 if it is passed an AF_INET/SOCK_STREAM socket with either the
5436 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5437 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5438 the socket it's been passed. This currently only applies to
5439 Windows. This option prevents any other sockets from binding to the
5440 host/port we've bound to, thus removing the possibility of the
5441 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5442 when a second SOCK_STREAM socket binds and accepts to a host/port
5443 that's already been bound by another socket. The optional preferred
5444 port parameter to bind_port() has been removed. Under no
5445 circumstances should tests be hard coding ports!
5446
5447 test_support.find_unused_port() has also been introduced, which will
5448 pass a temporary socket object to bind_port() in order to obtain an
5449 unused port. The temporary socket object is then closed and
5450 deleted, and the port is returned. This method should only be used
5451 for obtaining an unused port in order to pass to an external program
5452 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5453 a parameter to a server-oriented class that doesn't give you direct
5454 access to the underlying socket used.
5455
5456 Finally, test_support.HOST has been introduced, which should be used
5457 for the host argument of any relevant socket calls (i.e. bind and
5458 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005459
5460 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005461 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005462 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5463 test_asynchat and test_socket_ssl.
5464
Georg Brandl3ee81df2008-05-17 18:14:43 +00005465 It is now possible for multiple instances of the regression test
5466 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005745- Added the future_builtins module, which contains hex() and oct().
5746 These are the PEP 3127 version of these functions, designed to be
5747 compatible with the hex() and oct() builtins from Python 3.0. They
5748 differ slightly in their output formats from the existing, unchanged
5749 Python 2.6 builtins. The expected usage of the future_builtins
5750 module is:
5751 from future_builtins import hex, oct
5752
Eric Smith7ef40bf2008-02-20 23:34:22 +00005753- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5754 exponents for exponents with absolute value < 100. Follows C99
5755 standard. This is a change on Windows, which would use 3 digits.
5756 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5757 so that any alterations it does to the resulting string will be
5758 available in stringlib/formatter.h (for float.__format__).
5759
Eric Smith5a3c1352008-02-19 13:21:56 +00005760- Implemented PEP 3101, Advanced String Formatting. This adds a new
5761 builtin format(); a format() method for str and unicode; a
5762 __format__() method to object, str, unicode, int, long, float, and
5763 datetime; the class string.Formatter; and the C API
5764 PyObject_Format().
5765
Georg Brandl3ee81df2008-05-17 18:14:43 +00005766- Fixed several potential crashes, all caused by specially crafted
5767 __del__ methods exploiting objects in temporarily inconsistent
5768 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005769
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005770- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005771 prevent a possible crash: an Abstract Base Class would try to access
5772 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005773

Georg Brandl3ee81df2008-05-17 18:14:43 +00005777- Clear all free lists during a gc.collect() of the highest generation
5778 in order to allow pymalloc to free more arenas. Python may give back
5779 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005780
Georg Brandl3ee81df2008-05-17 18:14:43 +00005781- Issue #2045: Fix an infinite recursion triggered when printing a
5782 subclass of collections.defaultdict, if its default_factory is set
5783 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005784
Christian Heimesf75dbef2008-02-08 00:11:31 +00005785- Fixed a minor memory leak in dictobject.c. The content of the free
5786 list was not freed on interpreter shutdown.
5787
Georg Brandl21e99f42010-03-07 15:23:59 +00005788- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005789 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005790
Georg Brandl3ee81df2008-05-17 18:14:43 +00005791- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5792 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005793 to compact the internal free lists of pre-allocted ints and floats.
5794
Georg Brandl3ee81df2008-05-17 18:14:43 +00005795- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5796 calls. Python expected the return type int but the fork familie
5797 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005798
Georg Brandl3ee81df2008-05-17 18:14:43 +00005799- Issue #1678380: Fix a bug that identifies 0j and -0j when they
5800 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00005801
Georg Brandl3ee81df2008-05-17 18:14:43 +00005802- Issue #2025: Add tuple.count() and tuple.index() methods to comply
5803 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005811- Patch #1473257: generator objects gain a gi_code attribute. This is
5812 the same object as the func_code attribute of the function that
5813 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005814
Georg Brandl3ee81df2008-05-17 18:14:43 +00005815- Issue #1920: "while 0" statements were completely removed by the
5816 compiler, even in the presence of an "else" clause, which is
5817 supposed to be run when the condition is false. Now the compiler
5818 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005819
Guido van Rossumeead05f2008-01-24 18:21:02 +00005820- A few crashers fixed: weakref_in_del.py (issue #1377858);
5821 loosing_dict_ref.py (issue #1303614, test67.py);
5822 borrowed_ref_[34].py (not in tracker).
5823
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005824- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005825 suppressed while an extension is loaded by calling SetErrorMode in
5826 dynload_win.c. The error is still reported properly.
5827
Georg Brandl3ee81df2008-05-17 18:14:43 +00005828- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005829 several extension methods and modules do not work without unicode
5830 support.
5831
Georg Brandl26543b12008-01-21 18:36:51 +00005832- Issue #1882: when compiling code from a string, encoding cookies in the
5833 second line of code were not always recognized correctly.
5834
Georg Brandl14404b62008-01-19 19:27:05 +00005835- Issue #1679: "0x" was taken as a valid integer literal.
5836
Georg Brandl6caad7d2008-01-26 14:19:22 +00005837- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005838 added.
5839
Christian Heimesc94e2b52008-01-14 04:13:37 +00005840- sys.float_info / PyFloat_GetInfo: The floating point information
5841 object was converted from a dict to a specialized structseq object.
5842
Georg Brandl3ee81df2008-05-17 18:14:43 +00005843- Patch #1816: Added sys.flags structseq. It exposes the status of
5844 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005845
Georg Brandl3ee81df2008-05-17 18:14:43 +00005846- Objects/structseq.c: Implemented new structseq representation. The
5847 patch makes structseqs (e.g. the return value of os.stat) more
5848 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005849
Georg Brandl3ee81df2008-05-17 18:14:43 +00005850- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005907- Patch #1739468: Directories and zipfiles containing a __main__.py
5908 file can now be directly executed by passing their name to the
5909 interpreter. The directory/zipfile is automatically inserted as the
5910 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005912- Issue #1265: Fix a problem with sys.settrace, if the tracing
5913 function uses a generator expression when at the same time the
5914 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005915
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005916- sets and frozensets now have an isdisjoint() method.

5921
Georg Brandl21e99f42010-03-07 15:23:59 +00005922- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005923 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5924 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005925
Georg Brandl3ee81df2008-05-17 18:14:43 +00005926- Issue #1686386: Tuple's tp_repr did not take into account the
5927 possibility of having a self-referential tuple, which is possible
5928 from C code. Nor did object's tp_str consider that a type's tp_str
5929 could do something that could lead to an inifinite recursion.
5930 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5931 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005932
Georg Brandl3ee81df2008-05-17 18:14:43 +00005933- Issue #1164: It was possible to trigger deadlock when using the
5934 'print' statement to write to a file since the GIL was not released
5935 as needed. Now PyObject_Print() does the right thing along with
5936 various tp_print implementations of the built-in types and those in
5937 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005938
Georg Brandl3ee81df2008-05-17 18:14:43 +00005939- Issue #1147: Exceptions were directly allowing string exceptions in

5941 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00005946- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005947 PyObject_Call() never calling back out to Python code to trigger
5948 recursion depth updates/checks. Required the creation of a static
5949 RuntimeError instance in case normalizing an exception put the
5950 recursion check value past its limit. Fixes crashers
5951 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005966- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005967 __*__ attributes. (Some already existed, e.g., __doc__ and
5968 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005969
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005970- Add -3 option to the interpreter to warn about features that are
5971 deprecated and will be changed/removed in Python 3.0.
5972
Georg Brandl2134e752007-05-21 20:34:16 +00005973- Patch #1686487: you can now pass any mapping after '**' in function
5974 calls.
5975
Collin Winter62903052007-05-18 23:11:24 +00005976- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005977 "except E as target:". This is to provide forwards compatibility
5978 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005985- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005986 setting a plain string, ie don't expand to single letter identifiers.
5987
Raymond Hettinger13936692007-04-11 18:40:58 +00005988- Request #1191699: Slices can now be pickled.
5989
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005990- Request #1193128: str.translate() now allows a None argument for

5992 remaining characters.
5993
Georg Brandl5cb76c12007-03-21 09:00:39 +00005994- Patch #1682205: a TypeError while unpacking an iterable is no longer

5998
Guido van Rossum143b5642007-03-23 04:58:42 +00005999- Bug #1683368: The object.__init__() and object.__new__() methods are
6000 now stricter in rejecting excess arguments. The only time when
6001 either allows excess arguments is when it is not overridden and the
6002 other one is. For backwards compatibility, when both are
6003 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006004 warning later). Also, type.__init__() insists on the same signature
6005 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006006
Georg Brandl3ee81df2008-05-17 18:14:43 +00006007- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6008 object to complex using its __complex__() method before falling back
6009 to the __float__() method. Therefore, the functions in the cmath
6010 module now can operate on objects that define a __complex__()
6011 method.

6022 its type.

6028
Georg Brandl7b9c5552007-03-12 14:30:05 +00006029- Bug #1678647: write a newline after printing an exception in any
6030 case, even when converting the value to a string failed.
6031
Georg Brandl871f1bc2007-03-12 13:17:36 +00006032- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006033 its argument, if it exists. If not, it will work like before. This
6034 allows customizing the output of dir() in the presence of a
6035 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006043- Patch #1491866: change the complex() constructor to allow
6044 parthensized forms. This means complex(repr(x)) now works instead of
6045 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006046
Georg Brandlaa2321b2007-03-07 00:40:28 +00006047- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006048 makes the filenames the warning module prints much more sensible
6049 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006050

Georg Brandl0fca97a2007-03-05 22:28:08 +00006062- Patch #1674228: when assigning a slice (old-style), check for the
6063 sq_ass_slice instead of the sq_slice slot.
6064
Georg Brandl3ee81df2008-05-17 18:14:43 +00006065- When printing an unraisable error, don't print exceptions. before
6066 the name. This duplicates the behavior whening normally printing
6067 exceptions.

6633
Georg Brandl92a6bae2007-03-13 17:43:32 +00006634- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006635 are set for invalid interpolation sequences that would lead to

6692 TestCase and TestSuite subclasses (not instances) are no longer
6693 accepted in TestSuite.addTest(). This should cause no
6694 incompatibility since it never made sense with ordinary subclasses
6695 -- the failure just occurred later, with a more cumbersome
6696 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006977- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6978 with RFC 3207 and forgets any knowledge obtained from the server not
6979 obtained from the TLS negotiation itself. Patch contributed by Bill
6980 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006981
Georg Brandl3ee81df2008-05-17 18:14:43 +00006982- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006983 that the SMTP.starttls() caller no longer needs to call ehlo()
6984 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006985 does not claim to support starttls. Adds the
6986 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7067 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7068 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00007070

Georg Brandl3ee81df2008-05-17 18:14:43 +00007085 time so that opening a database previously created with the DB_DUP
7086 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7087 opens. Specifically: dictionary assignment to a DB object will
7088 replace all values for a given key when the database allows
7089 duplicate values. DB users should use DB.put(k, v) when they want
7090 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007091

7097 characters with ASCII value less than 32. Also, it correctly quotes
7098 dots only if they occur on a single line, as opposed to the previous
7099 behavior of quoting dots if they are the second character of any
7100 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007101

Guido van Rossum7c862f82007-12-13 20:50:10 +00007363- Bug #1608: use -fwrapv when GCC supports it. This is important,
7364 newer GCC versions may optimize away overflow buffer overflow checks
7365 without this option!
7366
Martin v. Löwis63bf1492007-11-12 05:14:05 +00007367- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
7368
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007369- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007370 periodic threadstate and signal checking in tight loops. By
7371 default, this option is turned-off. It should only be enabled in
7372 debugged, performance critical applications.

7388 returned by python-config if Python was built with --enable-shared
7389 because that prevented the shared library from being used.
7390

7423-----
7424
Georg Brandl3ee81df2008-05-17 18:14:43 +00007425- Unified naming convention for free lists and their limits. All free
7426 lists in Object/ are named ``free_list``, the counter ``numfree``
7427 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7428 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007429
Georg Brandl3ee81df2008-05-17 18:14:43 +00007430- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7431 to ``PyTuple_SetItem``, it can be used to populate a brand new
7432 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007433
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007434- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

7440- Patch #1720595: add T_BOOL to the range of structmember types.
7441
7442- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7443 ``PyFloat_GetInfo()`` to the float API.
7444
Georg Brandl3ee81df2008-05-17 18:14:43 +00007445- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7446 of w# format code incorrectly truncated the length to an int, even
7447 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7448 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007449
Georg Brandl3ee81df2008-05-17 18:14:43 +00007450- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7468- Fix some leftovers from the conversion from int to Py_ssize_t
7469 (relevant to strings and sequences of more than 2**31 items).
7470
7471- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7472 outside of pystate.c and should not be necessary.
7473
Georg Brandl3ee81df2008-05-17 18:14:43 +00007474- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7475 absolute imports. In earlier versions they might have used relative
7476 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007477
Georg Brandl3ee81df2008-05-17 18:14:43 +00007478- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7479 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007480
Georg Brandl3ee81df2008-05-17 18:14:43 +00007481- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

7489 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7490 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7491 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007492

Georg Brandl3ee81df2008-05-17 18:14:43 +00007506- Removed the macfs module. It had been deprecated since Python 2.5.
7507 This lead to the deprecation of macostools.touched() as it relied
7508 solely on macfs and was a no-op under OS X.
