Serhiy Storchaka6d562312013-12-17 14:40:06 +020012- Issue #17976: Fixed potential problem with file.write() not detecting IO error
13 by inspecting the return value of fwrite(). Based on patches by Jaakko Moisio
14 and Victor Stinner.
15
Victor Stinner66c6e9d2013-12-13 02:37:09 +010016- Issue #14432: Generator now clears the borrowed reference to the thread
17 state. Fix a crash when a generator is created in a C thread that is
18 destroyed while the generator is still used. The issue was that a generator
19 contains a frame, and the frame kept a reference to the Python state of the
20 destroyed C thread. The crash occurs when a trace function is setup.
21

34 executables used to find the mac address, with /sbin and /usr/sbin as
35 fallbacks.

Gregory P. Smith9ffb1482013-12-10 18:22:03 -080048- Issue #17200: telnetlib's read_until and expect timeout was broken by the
49 fix to Issue #14635 in Python 2.7.4 to be interpreted as milliseconds
50 instead of seconds when the platform supports select.poll (ie: everywhere).
51 It is now treated as seconds once again.
52

65 behaviour when Pickler.persistent_id returns None, but not for any other
Alexandre Vassalotti34ca0662013-11-30 14:02:47 -080066 false values. This allows false values other than None to be used as
67 persistent IDs. This behaviour is consistent with cPickle.
Alexandre Vassalotti1d3a1732013-11-30 13:24:13 -080068
Serhiy Storchaka6d9d30d2013-11-26 22:47:05 +020069- Issue #11508: Fixed uuid.getnode() and uuid.uuid1() on environment with

Ned Deily18fae3f2013-01-31 01:24:55 -08001517- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1518 In particular, fix extension module build failures when trying to use
1519 32-bit-only installer Pythons on systems with Xcode 4 (currently
1520 OS X 10.8, 10.7, and optionally 10.6).
1521 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1522 * Since Xcode 4 removes ppc support, extension module builds now
1523 check for ppc compiler support and by default remove ppc and
1524 ppc64 archs when they are not available.
1525 * Extension module builds now revert to using system installed
1526 headers and libs (/usr and /System/Library) if the SDK used
1527 to build the interpreter is not installed or has moved.
1528 * Try to avoid building extension modules with deprecated
1529 and problematic Apple llvm-gcc compiler. If original compiler
1530 is not available, use clang instead by default.

1883 incorrect results with recent versions of Clang, as a result of the

1885 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

1899 and its type get caught in a reference cycle, and the instance's

Ned Deily0d0ea482012-02-10 12:59:06 +01001961- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1962 Distutils-based packages with C extension modules may fail because
1963 Apple has removed gcc-4.2, the version used to build python.org
1964 64-bit/32-bit Pythons. If the user does not explicitly override
1965 the default C compiler by setting the CC environment variable,
1966 Distutils will now attempt to compile extension modules with clang
1967 if gcc-4.2 is required but not found. Also as a convenience, if
1968 the user does explicitly set CC, substitute its value as the default
1969 compiler in the Distutils LDSHARED configuration variable for OS X.
1970 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1971 SDK, neither of which are available in Xcode 4. This change does not
1972 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002222- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2223 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2224 interpreter process. This could cause failures in non-Distutils subprocesses
2225 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002226 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002227 deployment target only in the environment of each build subprocess. It is
2228 still possible to globally override the default by setting
2229 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2230 greater or equal to the default value, the value with which the interpreter
2231 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04002259- sys.setcheckinterval() now updates the current ticker count as well as
2260 updating the check interval, so if the user decreases the check interval,
2261 the ticker doesn't have to wind down to zero from the old starting point
2262 before the new interval takes effect. And if the user increases the
2263 interval, it makes sure the new limit takes effect right away rather have an
2264 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003244- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3245 This prevents user-created self-referencing ordered dictionaries from
3246 becoming permanently uncollectable GC garbage. The downside is that
3247 removing __del__ means that the internal doubly-linked list has to wait for
3248 GC collection rather than freeing memory immediately when the refcnt drops
3249 to zero.
3250

3278 falling into recursion.
3279
R. David Murray7c4bf552010-08-25 01:45:57 +00003280- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3281 character years even if the message contains RFC822 two character years.
3282
Daniel Stutzbach91287322010-08-24 21:09:30 +00003283- Issue #8750: Fixed MutableSet's methods to correctly handle

3312 and a BadZipfile error is raised if it doesn't match (as used to be the
3313 case in Python 2.5 and earlier).
3314
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003315- Issue #9550: a BufferedReader could issue an additional read when the
3316 original read request had been satisfied, which could block indefinitely
3317 when the underlying raw IO channel was e.g. a socket. Report and original
3318 patch by Jason V. Miller.
3319
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003320- Issue #9551: Don't raise TypeError when setting the value to None for

3339 This is how it is supposed to work, wget and curl do the same. Previous
3340 behavior was wrong.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003707- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

3709 of the number of bytes specified by the start byte.
3710 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3711 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3722 objects. (1) The comparison could incorrectly return True in some cases
3723 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004068 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4069 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4070 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4091-----------------
4092
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004093- Issue #7301: Add environment variable $PYTHONWARNINGS.
4094
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004095- Issue #8329: Don't return the same lists from select.select when no fds are
4096 changed.
4097
Georg Brandlfee0f442010-05-22 21:26:21 +00004098- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004099 on 64-bit machines. The shift count for either left or right shift is
4100 permitted to be up to sys.maxsize.
4101
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004102- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004106- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4107
Georg Brandlfee0f442010-05-22 21:26:21 +00004108- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4109 with a non-empty format string. This is an effort to future-proof user
4110 code. If a derived class does not currently implement __format__ but later
4111 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004112 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004113 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004114
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004115- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00004128- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004129 (SIGINT). If an error occurs while importing the site module, the error is

4145
Georg Brandlfee0f442010-05-22 21:26:21 +00004146- Issue #8257: The Decimal construct now accepts a float instance directly,
4147 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004148
4149 >>> Decimal(1.1)
4150 Decimal('1.100000000000000088817841970012523233890533447265625')
4151
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004152- collections.Counter() now supports a subtract() method.
4153
Georg Brandlfee0f442010-05-22 21:26:21 +00004154- The functools module now has a total_ordering() class decorator to simplify
4155 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004157- The functools module also adds cmp_to_key() as a tool to transition old-style
4158 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004159
Georg Brandlfee0f442010-05-22 21:26:21 +00004160- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4161 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004162
Georg Brandlfee0f442010-05-22 21:26:21 +00004163- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4164 InvalidOperation instead of returning False. (Comparisons involving a quiet
4165 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4166 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004167
Georg Brandlfee0f442010-05-22 21:26:21 +00004168- Issue #2531: Comparison operations between floats and Decimal instances now
4169 return a result based on the numeric values of the operands; previously they
4170 returned an arbitrary result based on the relative ordering of id(float) and
4171 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004172
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004173- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004174 argument `-` which tells it to read files to compile from stdin. Each line is
4175 read on demand and the named file is compiled immediately. (Original patch by
4176 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00004181- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4182 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004183 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004184
Georg Brandlfee0f442010-05-22 21:26:21 +00004185- Comparisons using one of <, <=, >, >= between a complex instance and a
4186 Fractions instance now raise TypeError instead of returning True/False. This
4187 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4188 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004256- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004287- Issue #8300: When passing a non-integer argument to struct.pack with any
4288 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00004292- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4293 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4294 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004295 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4296 inconsistent: __int__ was used for some integer codes but not for others, and
4297 the set of integer codes for which it was used differed between native packing
4298 and standard packing.)

4546 and add the additional members returned in an OSVERSIONINFOEX structure. The
4547 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00004550- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4551 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4552 returning NULL. The macro now returns a statically allocated empty string
4553 instead.

Antoine Pitroud840e512010-02-04 20:20:18 +00004598- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004599 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004605- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004606 file position when calling `truncate()`. It would previously change the file
4607 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004608 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4609
Georg Brandlba83f822010-03-14 09:50:54 +00004610- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4611 class used to represent files stored inside an archive. The new
4612 implementation is significantly faster and can be wrapped in a
4613 ``io.BufferedReader`` object for more speedups. It also solves an issue
4614 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4615 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004625- Issue #7748: Since unicode values are supported for some metadata options in
4626 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4627 encoded string for them. This ensures that the upload and register commands
4628 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004898- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4899 decimal string that's guaranteed to round back to x under correct rounding
4900 (with round-half-to-even rounding mode). Previously it gave a string based on
4901 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4902 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4903 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004904
Georg Brandlba83f822010-03-14 09:50:54 +00004905- Issue #7117: On almost all platforms: float-to-string and string-to-float
4906 conversions within Python are now correctly rounded. Places these conversions
4907 occur include: str for floats and complex numbers; the float and complex
4908 constructors; old-style and new-style numeric formatting; serialization and
4909 deserialization of floats and complex numbers using marshal, pickle and json;
4910 parsing of float and imaginary literals in Python code; Decimal-to-float
4911 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004912
Georg Brandlba83f822010-03-14 09:50:54 +00004913 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4914 providing correctly-rounded strtod and dtoa C functions. This code is
4915 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4916 the C compiler. There may be a small number of platforms on which correct
4917 operation of this code cannot be guaranteed, so the code is not used: notably,
4918 this applies to platforms where the C double format is not IEEE 754 binary64,
4919 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4920 and Python's configure script is unable to determine how to change the FPU
4921 precision. On these platforms conversions use the platform strtod and dtoa,
4922 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004924- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4925 uses the correctly-rounded string <-> float conversions described above (when
4926 available), and so produces correctly rounded results that will display nicely
4927 under the float repr. There are two related small changes: (1) round now
4928 accepts any class with an ``__index__()`` method for its second argument (but
4929 no longer accepts floats for the second argument), and (2) an excessively
4930 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4931 raises an exception.

Georg Brandl29c6a282009-04-05 20:23:13 +00005193- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00005194 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00005224- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5225 existing .py counterpart, override the co_filename attributes of all code
5226 objects if the original filename is obsolete (which can happen if the file has

5275
Georg Brandlba83f822010-03-14 09:50:54 +00005276- Issue #3689: The list reversed iterator now supports __length_hint__ instead

5281
Georg Brandlba83f822010-03-14 09:50:54 +00005282- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5283 file objects with closefd=False. The file descriptor is still kept open but
5284 the file object behaves like a closed file. The ``FileIO`` object also got a
5285 new readonly attribute ``closefd``.

5304
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005305- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005308- On windows, ``os.chdir()`` given unicode was not working if
5309 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5310 this code path is really executed because I cannot move to such directory on
5311 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005313- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5314 element is temporarily replaced with an equivalent frozenset. But the
5315 eventual KeyError would always report the empty ``frozenset()`` as the missing
5316 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005336- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5337 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5338 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5339 of using the replace error handler in PyUnicode_DecodeUTF8().
5340
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005341- Issue #3739: The unicode-internal encoder now reports the number of characters

5343
Georg Brandlba83f822010-03-14 09:50:54 +00005344- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5345 allocator will be automatically disabled when running under Valgrind. This
5346 gives improved memory leak detection when running under Valgrind, while taking
5347 advantage of pymalloc at other times.

6716
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006717- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6718 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6719 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6720 ``printf`` function, whereas PyString_FromFormat has an independent
6721 implementation and uses "%zd" on all platforms for size_t values.
6722 This makes a difference on win64, where ``printf`` needs "%Id" to display
6723 64bit values.

6729 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00006742- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006743 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6744 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6746 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6747 type object.

Gregory P. Smithd7122032008-09-02 05:36:11 +00006833- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
6834 non-integer floating point number.
6835

6841
Jesse Noller438195f2009-01-18 21:04:36 +00006842- Issue #4301: Patch the logging module to add processName support, remove
6843 _check_logger_class from multiprocessing.
6844
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006845- Issue #2975: When compiling several extension modules with Visual Studio 2008
6846 from the same python interpreter, some environment variables would grow
6847 without limit.
6848
Benjamin Peterson37346b22008-08-23 20:27:43 +00006849- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6850 exploitation of poor argument checking.
6851

6865 wrapper for warnings.catch_warnings() that makes it easier to check
6866 that expected warning messages are being reported.
6867
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00006868- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006886What's New in Python 2.6 beta 3?
6887================================
6888
Barry Warsaw07a4a382008-08-21 01:15:08 +00006889*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006890
6891Core and Builtins
6892-----------------
6893
Guido van Rossumf8402962008-08-20 15:01:50 +00006894- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6895 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6896 extensions do not automatically benefit from the class attribute
6897 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6898 to their tp_flags field if they care. This is a backwards
6899 compatibility feature; in 3.0, all types will use the cache by
6900 default.
6901
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006902- Keyword arguments can now follow starred arguments. (``f(a, *args,
6903 keyword=23)`` is now valid syntax.)
6904
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006905- ctypes function pointers that are COM methods have a boolean True
6906 value again.
6907
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006908- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6909 by denying s# to parse objects that have a releasebuffer procedure,
6910 and introducing s*.
6911
Georg Brandl1e13ea92008-08-11 09:07:59 +00006912- Issue #3537: Fix an assertion failure when an empty but presized dict
6913 object was stored in the freelist.
6914
Mark Dickinsonb6467572008-08-04 21:30:09 +00006915- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6916 ValueError consistently across platforms.
6917
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006918- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6919 (64bit Unix, for example), unichr() would truncate its argument and return
6920 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6921
Neal Norwitze7d8be82008-07-31 17:17:14 +00006922- Apply security patches from Apple.
6923
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006924- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6925 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6926
Antoine Pitrou92f82162008-07-25 22:22:08 +00006927- Issue #1819: function calls with several named parameters are now on
6928 average 35% faster (as measured by pybench).
6929
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006930- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6931 the python debugger steps into a class statement: the free variables (local
6932 variables defined in an outer scope) would be deleted from the outer scope.
6933
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006934- Issue #2620: Overflow checking when allocating or reallocating memory
6935 was not always being done properly in some python types and extension
6936 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6937 all been updated to perform better checks and places in the code that
6938 would previously leak memory on the error path when such an allocation
6939 failed have been fixed.
6940
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006941Library
6942-------
6943
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006944- Issue #3612: Added some missing basic types in ctypes.wintypes.
6945
Benjamin Petersone977ad42008-08-20 01:42:01 +00006946- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6947 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6948
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006949- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6950 version reported by these tools does not necessarily follow the python
6951 version numbering scheme, so the module is less strict when parsing it.
6952
Nick Coghlanf70385a2008-08-18 12:42:46 +00006953- Issue #2235: Added Py3k warnings for types which will become unhashable
6954 under the stricter __hash__ inheritance rules in 3.0. Several types
6955 which did not meet the rules for hash invariants and were already
6956 unhashable in 3.0 have now been explicitly flagged as unhashable in
6957 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6958 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6959
Brett Cannon88f801d2008-08-18 00:46:22 +00006960- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6961 imported into the module but exposed as part of the module's API.
6962
Brett Cannon7b96f072008-08-18 00:41:11 +00006963- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6964
Brett Cannon46225e72008-08-18 00:36:52 +00006965- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6966
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006967- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6968
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006969- Issue #3575: Incremental decoder's decode function now takes bytearray
6970 by using 's*' instead of 't#'.
6971
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006972- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006973 fails unicode conversion on 2nd parameter. (windows only)
6974
Georg Brandl222e2082010-08-01 22:27:39 +00006975- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006976 in a redirect.
6977
Brett Cannonabe423e2008-08-16 21:47:07 +00006978- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006979 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006980
Facundo Batistaeb90b782008-08-16 14:44:07 +00006981- Issue #2776: fixed small issue when handling an URL with double slash
6982 after a 302 response in the case of not going through a proxy.
6983
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006984- Issue #2676: in the email package, content-type parsing was hanging on
6985 pathological input because of quadratic or exponential behaviour of a
6986 regular expression.
6987
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006988- Issue #3476: binary buffered reading through the new "io" library is now
6989 thread-safe.
6990
Brett Cannonbf3157b2008-08-14 05:00:03 +00006991- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6992 since mimetools itself is deprecated. Because modules are cached, all
6993 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6994
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006995- Issue #3134: shutil referenced undefined WindowsError symbol.
6996
Robert Schuppenies14646332008-08-10 11:01:53 +00006997- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6998 menu entries were not deleted.
6999
Brett Cannon83e81842008-08-09 23:30:55 +00007000- Copied the implementation of reduce() to _functools.reduce() to have a
7001 version that did not raise a DeprecationWarning under -3.
7002
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007003- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7004 a MemoryError rather than silently stop the iteration.
7005
Guido van Rossum59ce9012008-08-09 14:55:34 +00007006- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7007 to _sre.compile() will now be rejected. This should not affect anybody
7008 since the re.compile() function never generates invalid re-bytecode.
7009
Skip Montanaroa032bf42008-08-08 22:52:51 +00007010- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7011 upon first access it can be automatically initialized from the csv file if
7012 it wasn't initialized during instantiation.
7013
Brett Cannon3aa2a492008-08-06 22:28:09 +00007014- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7015 the reload() built-in has been removed.
7016
Brett Cannon7e30b672008-08-04 21:52:25 +00007017- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007018 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7026 raised an AttributeError.
7027
Benjamin Peterson01a24322008-07-28 23:35:27 +00007028- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007029 asking for a specific length. This problem only affected files opened
7030 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007031
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007032- Issue #3449: Update decimal module to use most recent specification
7033 (v. 1.68) and tests (v. 2.58) from IBM.

7054
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007055- Issue #3394: zipfile.writestr sets external attributes when passed a
7056 file name rather than a ZipInfo instance, so files are extracted with
7057 mode 0600 rather than 000 under Unix.
7058
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007059- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7060 argument in python 2.5, this broke code that subclassed Popen to include its
7061 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007071- Issue #2235: the C API function PyObject_HashNotImplemented and its
7072 interaction with the tp_hash slot (added in 2.6b2) are now documented
7073
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007074- Issue #643841: The language reference now provides more detailed
7075 coverage of the lookup process for special methods. The disclaimers
7076 regarding lack of coverage of new-style classes have also been
7077 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007080What's New in Python 2.6 beta 2?
7081================================
7082
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007083*Release date: 17-Jul-2008*
7084
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007085Core and Builtins
7086-----------------
7087
Georg Brandl3e483f62008-07-16 22:57:41 +00007088- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7089 its methods now allow for items objects that can be converted to
7090 an integer using operator.index().
7091
Mark Dickinson64b7e502008-07-16 09:40:03 +00007092- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7093 produced a ValueError instead of giving the correct float.
7094
Eric Smitha5fa5a22008-07-16 00:11:49 +00007095- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7096 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7097
Mark Dickinson7103aa42008-07-15 19:08:33 +00007098- Issue #3008: the float type has a new instance method 'float.hex'
7099 and a new class method 'float.fromhex' to convert floating-point
7100 numbers to and from hexadecimal strings, respectively.
7101
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007102- Issue #2235: __hash__ is once again inherited by default. To allow
7103 collections.Hashable to remain meaningful in the presence of the
7104 default hash implementation (object.__hash__), it is now possible
7105 to explicit block inheritance of hash by setting __hash__=None at
7106 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7107 level.
7108
Nick Coghlanb028f502008-07-13 14:52:36 +00007109- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7110 the parent module cannot be found while performing an absolute import.
7111 This means that an incorrectly defined __package__ attribute will
7112 now only prevent relative imports in that module rather than causing
7113 all imports from that module to fail.
7114
Nick Coghlan14ff9942008-07-08 14:21:42 +00007115- Issue #2517: Allow unicode messages in Exceptions again by correctly
7116 bypassing the instance dictionary when looking up __unicode__ on
7117 new-style classes.
7118
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007119- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

Georg Brandl5cc774e2008-06-11 20:28:06 +00007584 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007585
7586 This is controlled by the configure argument ``--with-universal-archs``:
7587

7589
7590 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7591
7592 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7593

Georg Brandl3ee81df2008-05-17 18:14:43 +00007645- Issue #1631171: Re-implement the 'warnings' module in C (the
7646 original Python code has been kept as backup). This will allow for
7647 using the 'warning's machinery in such places as the parser where
7648 use of pure Python code is not possible. Both the ``showarning()``
7649 and ``formatwarning()`` gain an optional 'line' argument which is
7650 not called by default for backwards-compatibility reasons. Setting
7651 ``warnings.showwarning()`` to an implementation that lacks support
7652 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007715- Issue #2550: The approach used by client/server code for obtaining
7716 ports to listen on in network-oriented tests has been refined in an
7717 effort to facilitate running multiple instances of the entire
7718 regression test suite in parallel without issue.
7719 test_support.bind_port() has been fixed such that it will always
7720 return a unique port -- which wasn't always the case with the
7721 previous implementation, especially if socket options had been set
7722 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7723 new implementation of bind_port() will actually raise an exception
7724 if it is passed an AF_INET/SOCK_STREAM socket with either the
7725 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7726 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7727 the socket it's been passed. This currently only applies to
7728 Windows. This option prevents any other sockets from binding to the
7729 host/port we've bound to, thus removing the possibility of the
7730 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7731 when a second SOCK_STREAM socket binds and accepts to a host/port
7732 that's already been bound by another socket. The optional preferred
7733 port parameter to bind_port() has been removed. Under no
7734 circumstances should tests be hard coding ports!
7735
7736 test_support.find_unused_port() has also been introduced, which will
7737 pass a temporary socket object to bind_port() in order to obtain an
7738 unused port. The temporary socket object is then closed and
7739 deleted, and the port is returned. This method should only be used
7740 for obtaining an unused port in order to pass to an external program
7741 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7742 a parameter to a server-oriented class that doesn't give you direct
7743 access to the underlying socket used.
7744
7745 Finally, test_support.HOST has been introduced, which should be used
7746 for the host argument of any relevant socket calls (i.e. bind and
7747 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007748
7749 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007750 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007751 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7752 test_asynchat and test_socket_ssl.
7753
Georg Brandl3ee81df2008-05-17 18:14:43 +00007754 It is now possible for multiple instances of the regression test
7755 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007939 optional: it defaults to the traceback of the exception that is
7940 currently being handled (is mandatory to be in the middle of an
7941 exception, otherwise it raises ValueError).

7960 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007961 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
7962 files are used. On all linux systems the --with-system-ffi
7963 configure option defaults to "yes".

Georg Brandlad61bc82008-02-23 15:11:18 +00008027- Issue #2067: file.__exit__() now calls subclasses' close() method.
8028
8029- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008030
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008031- Issue #1881: An internal parser limit has been increased. Also see

Facundo Batistafc2d0102008-02-23 12:01:13 +00008033
Eric Smitha73fbe72008-02-23 03:09:44 +00008034- Added the future_builtins module, which contains hex() and oct().
8035 These are the PEP 3127 version of these functions, designed to be
8036 compatible with the hex() and oct() builtins from Python 3.0. They
8037 differ slightly in their output formats from the existing, unchanged
8038 Python 2.6 builtins. The expected usage of the future_builtins
8039 module is:
8040 from future_builtins import hex, oct
8041
Eric Smith7ef40bf2008-02-20 23:34:22 +00008042- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8043 exponents for exponents with absolute value < 100. Follows C99
8044 standard. This is a change on Windows, which would use 3 digits.
8045 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8046 so that any alterations it does to the resulting string will be
8047 available in stringlib/formatter.h (for float.__format__).
8048
Eric Smith5a3c1352008-02-19 13:21:56 +00008049- Implemented PEP 3101, Advanced String Formatting. This adds a new
8050 builtin format(); a format() method for str and unicode; a
8051 __format__() method to object, str, unicode, int, long, float, and
8052 datetime; the class string.Formatter; and the C API
8053 PyObject_Format().
8054
Georg Brandl3ee81df2008-05-17 18:14:43 +00008055- Fixed several potential crashes, all caused by specially crafted
8056 __del__ methods exploiting objects in temporarily inconsistent
8057 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008058
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008059- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008060 prevent a possible crash: an Abstract Base Class would try to access
8061 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008062
Georg Brandl3ee81df2008-05-17 18:14:43 +00008063- Fixed repr() and str() of complex numbers with infinity or nan as
8064 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008066- Clear all free lists during a gc.collect() of the highest generation
8067 in order to allow pymalloc to free more arenas. Python may give back
8068 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008069
Georg Brandl3ee81df2008-05-17 18:14:43 +00008070- Issue #2045: Fix an infinite recursion triggered when printing a
8071 subclass of collections.defaultdict, if its default_factory is set
8072 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008073
Christian Heimesf75dbef2008-02-08 00:11:31 +00008074- Fixed a minor memory leak in dictobject.c. The content of the free
8075 list was not freed on interpreter shutdown.
8076
Georg Brandl21e99f42010-03-07 15:23:59 +00008077- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008078 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008079
Georg Brandl3ee81df2008-05-17 18:14:43 +00008080- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8081 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008082 to compact the internal free lists of pre-allocted ints and floats.
8083
Georg Brandl3ee81df2008-05-17 18:14:43 +00008084- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8085 calls. Python expected the return type int but the fork familie
8086 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008087
Georg Brandl3ee81df2008-05-17 18:14:43 +00008088- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8089 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008090
Georg Brandl3ee81df2008-05-17 18:14:43 +00008091- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8092 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008097- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8098 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008099
Georg Brandl3ee81df2008-05-17 18:14:43 +00008100- Patch #1473257: generator objects gain a gi_code attribute. This is
8101 the same object as the func_code attribute of the function that
8102 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008103
Georg Brandl3ee81df2008-05-17 18:14:43 +00008104- Issue #1920: "while 0" statements were completely removed by the
8105 compiler, even in the presence of an "else" clause, which is
8106 supposed to be run when the condition is false. Now the compiler
8107 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008108
Guido van Rossumeead05f2008-01-24 18:21:02 +00008109- A few crashers fixed: weakref_in_del.py (issue #1377858);
8110 loosing_dict_ref.py (issue #1303614, test67.py);
8111 borrowed_ref_[34].py (not in tracker).
8112
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008113- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008114 suppressed while an extension is loaded by calling SetErrorMode in
8115 dynload_win.c. The error is still reported properly.
8116
Georg Brandl3ee81df2008-05-17 18:14:43 +00008117- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008118 several extension methods and modules do not work without unicode
8119 support.
8120
Georg Brandl26543b12008-01-21 18:36:51 +00008121- Issue #1882: when compiling code from a string, encoding cookies in the
8122 second line of code were not always recognized correctly.
8123
Georg Brandl14404b62008-01-19 19:27:05 +00008124- Issue #1679: "0x" was taken as a valid integer literal.
8125
Georg Brandl6caad7d2008-01-26 14:19:22 +00008126- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008127 added.
8128
Christian Heimesc94e2b52008-01-14 04:13:37 +00008129- sys.float_info / PyFloat_GetInfo: The floating point information
8130 object was converted from a dict to a specialized structseq object.
8131
Georg Brandl3ee81df2008-05-17 18:14:43 +00008132- Patch #1816: Added sys.flags structseq. It exposes the status of
8133 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008134
Georg Brandl3ee81df2008-05-17 18:14:43 +00008135- Objects/structseq.c: Implemented new structseq representation. The
8136 patch makes structseqs (e.g. the return value of os.stat) more
8137 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008138
Georg Brandl3ee81df2008-05-17 18:14:43 +00008139- Patch #1700288: added a type attribute cache that caches method

8148 envvar and sys.dont_write_bytecode attribute. All these can be set
8149 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008150
Georg Brandl3ee81df2008-05-17 18:14:43 +00008151- Improve some exception messages when Windows fails to load an
8152 extension module. Now we get for example '%1 is not a valid Win32
8153 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008161 and INF. float("nan"), float("inf") and float("-inf") now work on
8162 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008163
Georg Brandl3ee81df2008-05-17 18:14:43 +00008164- Compiler now generates simpler and faster code for dictionary
8165 literals. The oparg for BUILD_MAP now indicates an estimated
8166 dictionary size. There is a new opcode, STORE_MAP, for adding
8167 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008196- Patch #1739468: Directories and zipfiles containing a __main__.py
8197 file can now be directly executed by passing their name to the
8198 interpreter. The directory/zipfile is automatically inserted as the
8199 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008201- Issue #1265: Fix a problem with sys.settrace, if the tracing
8202 function uses a generator expression when at the same time the
8203 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008204
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008205- sets and frozensets now have an isdisjoint() method.
8206

8210
Georg Brandl21e99f42010-03-07 15:23:59 +00008211- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008212 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8213 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008214
Georg Brandl3ee81df2008-05-17 18:14:43 +00008215- Issue #1686386: Tuple's tp_repr did not take into account the
8216 possibility of having a self-referential tuple, which is possible
8217 from C code. Nor did object's tp_str consider that a type's tp_str
8218 could do something that could lead to an inifinite recursion.
8219 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8220 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008221
Georg Brandl3ee81df2008-05-17 18:14:43 +00008222- Issue #1164: It was possible to trigger deadlock when using the
8223 'print' statement to write to a file since the GIL was not released
8224 as needed. Now PyObject_Print() does the right thing along with
8225 various tp_print implementations of the built-in types and those in
8226 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008227
Georg Brandl3ee81df2008-05-17 18:14:43 +00008228- Issue #1147: Exceptions were directly allowing string exceptions in
8229 their throw() method even though string exceptions no longer
8230 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008231
Georg Brandl3ee81df2008-05-17 18:14:43 +00008232- Issue #1096: Prevent a segfault from getting the repr of a very
8233 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008234
Brett Cannon1e534b52007-09-07 04:18:30 +00008235- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008236 PyObject_Call() never calling back out to Python code to trigger
8237 recursion depth updates/checks. Required the creation of a static
8238 RuntimeError instance in case normalizing an exception put the
8239 recursion check value past its limit. Fixes crashers
8240 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008241
Georg Brandl3ee81df2008-05-17 18:14:43 +00008242- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008255- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008256 __*__ attributes. (Some already existed, e.g., __doc__ and
8257 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008258
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008259- Add -3 option to the interpreter to warn about features that are
8260 deprecated and will be changed/removed in Python 3.0.
8261
Georg Brandl2134e752007-05-21 20:34:16 +00008262- Patch #1686487: you can now pass any mapping after '**' in function
8263 calls.
8264
Collin Winter62903052007-05-18 23:11:24 +00008265- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008266 "except E as target:". This is to provide forwards compatibility
8267 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008268
Brett Cannon229cee22007-05-05 01:34:02 +00008269- Deprecate BaseException.message as per PEP 352.
8270
Georg Brandl3ee81df2008-05-17 18:14:43 +00008271- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008272 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008273
Vinay Sajip8549ce32007-05-06 17:53:37 +00008274- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008275 setting a plain string, ie don't expand to single letter identifiers.
8276
Raymond Hettinger13936692007-04-11 18:40:58 +00008277- Request #1191699: Slices can now be pickled.
8278
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008279- Request #1193128: str.translate() now allows a None argument for
8280 translations that only remove characters without re-mapping the
8281 remaining characters.
8282
Georg Brandl5cb76c12007-03-21 09:00:39 +00008283- Patch #1682205: a TypeError while unpacking an iterable is no longer
8284 masked by a generic one with the message "unpack non-sequence".
8285
Neal Norwitzaa754b72007-03-21 06:39:48 +00008286- Remove unused file Python/fmod.c.
8287
Guido van Rossum143b5642007-03-23 04:58:42 +00008288- Bug #1683368: The object.__init__() and object.__new__() methods are
8289 now stricter in rejecting excess arguments. The only time when
8290 either allows excess arguments is when it is not overridden and the
8291 other one is. For backwards compatibility, when both are
8292 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008293 warning later). Also, type.__init__() insists on the same signature
8294 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008295
Georg Brandl3ee81df2008-05-17 18:14:43 +00008296- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8297 object to complex using its __complex__() method before falling back
8298 to the __float__() method. Therefore, the functions in the cmath
8299 module now can operate on objects that define a __complex__()
8300 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008301
Georg Brandl3ee81df2008-05-17 18:14:43 +00008302- Patch #1623563: allow __class__ assignment for classes with
8303 __slots__. The old and the new class are still required to have the
8304 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008305
Georg Brandl3ee81df2008-05-17 18:14:43 +00008306- Patch #1642547: Fix an error/crash when encountering syntax errors

8310 ``object.__reduce_ex__()`` is called with an object that is faking
8311 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008312
Georg Brandl3ee81df2008-05-17 18:14:43 +00008313- Patch #1680015: Don't modify __slots__ tuple if it contains an

8317
Georg Brandl7b9c5552007-03-12 14:30:05 +00008318- Bug #1678647: write a newline after printing an exception in any
8319 case, even when converting the value to a string failed.
8320
Georg Brandl871f1bc2007-03-12 13:17:36 +00008321- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008322 its argument, if it exists. If not, it will work like before. This
8323 allows customizing the output of dir() in the presence of a
8324 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008325
Collin Winter276887b2007-03-12 16:11:39 +00008326- Patch #922167: Python no longer segfaults when faced with infinitely
8327 self-recursive reload() calls (as reported by bug #742342).
8328
Georg Brandl3ee81df2008-05-17 18:14:43 +00008329- Patch #1675981: remove unreachable code from ``type.__new__()``
8330 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008332- Patch #1491866: change the complex() constructor to allow
8333 parthensized forms. This means complex(repr(x)) now works instead of
8334 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008335
Georg Brandlaa2321b2007-03-07 00:40:28 +00008336- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008337 makes the filenames the warning module prints much more sensible
8338 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008339
Georg Brandl49aafc92007-03-07 00:34:46 +00008340- Variant of patch #697613: don't exit the interpreter on a SystemExit
8341 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008342 variable is given, but break into the interactive interpreter just
8343 like on other exceptions or normal program exit.

8349 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00008350
Georg Brandl0fca97a2007-03-05 22:28:08 +00008351- Patch #1674228: when assigning a slice (old-style), check for the
8352 sq_ass_slice instead of the sq_slice slot.
8353
Georg Brandl3ee81df2008-05-17 18:14:43 +00008354- When printing an unraisable error, don't print exceptions. before
8355 the name. This duplicates the behavior whening normally printing
8356 exceptions.

Georg Brandl4e933132006-09-06 20:05:58 +00008439- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Guido van Rossum8bc09652008-02-21 18:18:37 +00008497- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00008923 are set for invalid interpolation sequences that would lead to

8980 TestCase and TestSuite subclasses (not instances) are no longer
8981 accepted in TestSuite.addTest(). This should cause no

8983 -- the failure just occurred later, with a more cumbersome
8984 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009259- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9260 with RFC 3207 and forgets any knowledge obtained from the server not
9261 obtained from the TLS negotiation itself. Patch contributed by Bill
9262 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009263
Georg Brandl3ee81df2008-05-17 18:14:43 +00009264- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009265 that the SMTP.starttls() caller no longer needs to call ehlo()
9266 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009267 does not claim to support starttls. Adds the
9268 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9269 Fenner.

9307
Georg Brandl3ee81df2008-05-17 18:14:43 +00009308- Patch #1663329: added ``os.closerange()`` function to quickly close

Georg Brandl3ee81df2008-05-17 18:14:43 +00009311- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009312 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +00009323- itertools.chain() now has an alternate constructor,

9349 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9350 silently miscode subclasses of those types. Now, it raises a
9351 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009352

Georg Brandl3ee81df2008-05-17 18:14:43 +00009367 time so that opening a database previously created with the DB_DUP
9368 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9369 opens. Specifically: dictionary assignment to a DB object will
9370 replace all values for a given key when the database allows
9371 duplicate values. DB users should use DB.put(k, v) when they want
9372 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009373

9379 characters with ASCII value less than 32. Also, it correctly quotes
9380 dots only if they occur on a single line, as opposed to the previous
9381 behavior of quoting dots if they are the second character of any
9382 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009383
Georg Brandla47337f2007-03-13 12:34:25 +00009384- Bug #1622896: fix a rare corner case where the bz2 module raised an

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009657- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00009658 periodic threadstate and signal checking in tight loops. By
9659 default, this option is turned-off. It should only be enabled in
9660 debugged, performance critical applications.

9715 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009716
Georg Brandl3ee81df2008-05-17 18:14:43 +00009717- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9718 to ``PyTuple_SetItem``, it can be used to populate a brand new
9719 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009720

9731
Georg Brandl3ee81df2008-05-17 18:14:43 +00009732- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9733 of w# format code incorrectly truncated the length to an int, even
9734 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9735 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009736
Georg Brandl3ee81df2008-05-17 18:14:43 +00009737- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9757
9758- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9759 outside of pystate.c and should not be necessary.
9760
Georg Brandl3ee81df2008-05-17 18:14:43 +00009761- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9762 absolute imports. In earlier versions they might have used relative
9763 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009764
Georg Brandl3ee81df2008-05-17 18:14:43 +00009765- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9766 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009767
Georg Brandl3ee81df2008-05-17 18:14:43 +00009768- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009791- Removed the macfs module. It had been deprecated since Python 2.5.
9792 This lead to the deprecation of macostools.touched() as it relied
9793 solely on macfs and was a no-op under OS X.
