Mark Dickinsondbbed042011-09-19 16:38:08 +0100902- Issue #12973: Fix overflow checks that invoked undefined behaviour in
903 int.__pow__. These overflow checks were causing int.__pow__ to produce
904 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100905 compiler optimizing the check away. Also fix similar overflow checks
906 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
907 bugs caused test failures with recent versions of Clang.

919 cleared by the garbage collector. This fixes a segfault when an instance
920 and its type get caught in a reference cycle, and the instance's
921 deallocator calls one of the methods on the type (e.g. when subclassing
922 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunac2279652012-02-12 14:49:03 +0100975- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100976 has left two versions of customize_compiler, the original in
977 distutils.sysconfig and another copy in distutils.ccompiler, with some
978 parts of distutils calling one and others using the other.

980 is the case in 3.x.
981
Ned Deily0d0ea482012-02-10 12:59:06 +0100982- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
983 Distutils-based packages with C extension modules may fail because
984 Apple has removed gcc-4.2, the version used to build python.org
985 64-bit/32-bit Pythons. If the user does not explicitly override
986 the default C compiler by setting the CC environment variable,
987 Distutils will now attempt to compile extension modules with clang
988 if gcc-4.2 is required but not found. Also as a convenience, if
989 the user does explicitly set CC, substitute its value as the default
990 compiler in the Distutils LDSHARED configuration variable for OS X.
991 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
992 SDK, neither of which are available in Xcode 4. This change does not
993 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001266- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1267 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1268 interpreter process. This could cause failures in non-Distutils subprocesses
1269 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001270 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001271 deployment target only in the environment of each build subprocess. It is
1272 still possible to globally override the default by setting
1273 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1274 greater or equal to the default value, the value with which the interpreter
1275 was built.

1305 the ticker doesn't have to wind down to zero from the old starting point
1306 before the new interval takes effect. And if the user increases the
1307 interval, it makes sure the new limit takes effect right away rather have an
1308 early task switch before recognizing the new interval.

2260 This prevents user-created self-referencing ordered dictionaries from
2261 becoming permanently uncollectable GC garbage. The downside is that
2262 removing __del__ means that the internal doubly-linked list has to wait for
2263 GC collection rather than freeing memory immediately when the refcnt drops
2264 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002723- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2724 start byte and the continuation byte(s) are now considered invalid, instead
2725 of the number of bytes specified by the start byte.
2726 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2727 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2728 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002737- Issue #8748: Fix two issues with comparisons between complex and integer
2738 objects. (1) The comparison could incorrectly return True in some cases
2739 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2740 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00002881- Issue #1533: Fix inconsistency in range function argument processing: any
2882 non-float non-integer argument is now converted to an integer (if possible)
2883 using its __int__ method. Previously, only small arguments were treated this
2884 way; larger arguments (those whose __int__ was outside the range of a C long)
2885 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00003114- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003115 on 64-bit machines. The shift count for either left or right shift is
3116 permitted to be up to sys.maxsize.
3117
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003118- Ensure that tokenization of identifiers is not affected by locale.
3119
Georg Brandlfee0f442010-05-22 21:26:21 +00003120- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003121
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003122- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3123
Georg Brandlfee0f442010-05-22 21:26:21 +00003124- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3125 with a non-empty format string. This is an effort to future-proof user
3126 code. If a derived class does not currently implement __format__ but later
3127 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003128 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003129 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003130
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003131- Issue #8268: Old-style classes (not just instances) now support weak
3132 references.

Victor Stinner66644262010-03-10 22:30:19 +00003144- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003145 (SIGINT). If an error occurs while importing the site module, the error is
3146 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003147 module.

3161
Georg Brandlfee0f442010-05-22 21:26:21 +00003162- Issue #8257: The Decimal construct now accepts a float instance directly,
3163 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003164
3165 >>> Decimal(1.1)
3166 Decimal('1.100000000000000088817841970012523233890533447265625')
3167
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003168- collections.Counter() now supports a subtract() method.
3169
Georg Brandlfee0f442010-05-22 21:26:21 +00003170- The functools module now has a total_ordering() class decorator to simplify
3171 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003173- The functools module also adds cmp_to_key() as a tool to transition old-style
3174 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003175
Georg Brandlfee0f442010-05-22 21:26:21 +00003176- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3177 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00003179- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3180 InvalidOperation instead of returning False. (Comparisons involving a quiet
3181 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3182 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003183
Georg Brandlfee0f442010-05-22 21:26:21 +00003184- Issue #2531: Comparison operations between floats and Decimal instances now
3185 return a result based on the numeric values of the operands; previously they
3186 returned an arbitrary result based on the relative ordering of id(float) and
3187 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003188
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003189- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003190 argument `-` which tells it to read files to compile from stdin. Each line is
3191 read on demand and the named file is compiled immediately. (Original patch by
3192 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003193
Georg Brandlfee0f442010-05-22 21:26:21 +00003194- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00003197- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3198 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003199 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003200
Georg Brandlfee0f442010-05-22 21:26:21 +00003201- Comparisons using one of <, <=, >, >= between a complex instance and a
3202 Fractions instance now raise TypeError instead of returning True/False. This
3203 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3204 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003205

Georg Brandlfee0f442010-05-22 21:26:21 +00003216 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3217 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003218
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003219- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3220 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00003260 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3261 log file to compute the next rollover time. If the log file does not exist,
3262 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003263

Georg Brandlba83f822010-03-14 09:50:54 +00003272- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3273 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3274 This is a behavior change, so email's minor version number is now bumped, to

Georg Brandlfee0f442010-05-22 21:26:21 +00003311 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3312 inconsistent: __int__ was used for some integer codes but not for others, and
3313 the set of integer codes for which it was used differed between native packing
3314 and standard packing.)

Mark Dickinson8efef5c2010-01-12 22:23:56 +00003577
Georg Brandlba83f822010-03-14 09:50:54 +00003578 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
3579 strings,
3580 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3581 numeric strings corresponding to subnormal values,
3582 (3) a memory leak for some values large enough to cause overflow, and
3583 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00003622 file position when calling `truncate()`. It would previously change the file
3623 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003624 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3627 class used to represent files stored inside an archive. The new
3628 implementation is significantly faster and can be wrapped in a
3629 ``io.BufferedReader`` object for more speedups. It also solves an issue
3630 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3643 encoded string for them. This ensures that the upload and register commands
3644 send the correct values to PyPI without any error.

3718Core and Builtins
3719-----------------
3720
Georg Brandlba83f822010-03-14 09:50:54 +00003721- The ``__complex__()`` method is now looked up on the class of instances to
3722 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003723
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003724- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3725 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3726
Mark Dickinson1b34d252010-01-01 17:27:30 +00003727- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003728 DeprecationWarning when passed a float argument where an integer was expected.
3729 These functions and methods now raise TypeError instead. The majority of the
3730 effects of this change are in the extension modules, but some core functions
3731 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3732 and many unicode/str methods.

3743 used to drop the time part of the result.
3744
Georg Brandlba83f822010-03-14 09:50:54 +00003745- Issue #1811: Improve accuracy and cross-platform consistency for true division
3746 of integers: the result of a/b is now correctly rounded for ints a and b (at
3747 least on IEEE 754 platforms), and in particular does not depend on the
3748 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003749
Georg Brandlba83f822010-03-14 09:50:54 +00003750- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
3751 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
3752 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00003755 executables on OSX.
3756
Georg Brandlba83f822010-03-14 09:50:54 +00003757 These executables now work properly with the arch(1) command: ``arch -ppc
3758 python`` will start a universal binary version of python in PPC mode (unlike
3759 previous releases).

3899 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003900

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003914
Georg Brandlba83f822010-03-14 09:50:54 +00003915- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3916 decimal string that's guaranteed to round back to x under correct rounding
3917 (with round-half-to-even rounding mode). Previously it gave a string based on
3918 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3919 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3920 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003921
Georg Brandlba83f822010-03-14 09:50:54 +00003922- Issue #7117: On almost all platforms: float-to-string and string-to-float
3923 conversions within Python are now correctly rounded. Places these conversions
3924 occur include: str for floats and complex numbers; the float and complex
3925 constructors; old-style and new-style numeric formatting; serialization and
3926 deserialization of floats and complex numbers using marshal, pickle and json;
3927 parsing of float and imaginary literals in Python code; Decimal-to-float
3928 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003929
Georg Brandlba83f822010-03-14 09:50:54 +00003930 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3931 providing correctly-rounded strtod and dtoa C functions. This code is
3932 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3933 the C compiler. There may be a small number of platforms on which correct
3934 operation of this code cannot be guaranteed, so the code is not used: notably,
3935 this applies to platforms where the C double format is not IEEE 754 binary64,
3936 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3937 and Python's configure script is unable to determine how to change the FPU
3938 precision. On these platforms conversions use the platform strtod and dtoa,
3939 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003940
Georg Brandlba83f822010-03-14 09:50:54 +00003941- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3942 uses the correctly-rounded string <-> float conversions described above (when
3943 available), and so produces correctly rounded results that will display nicely
3944 under the float repr. There are two related small changes: (1) round now
3945 accepts any class with an ``__index__()`` method for its second argument (but
3946 no longer accepts floats for the second argument), and (2) an excessively
3947 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3948 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004091 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4092 (2) parsing of strings representing infinities and nans was locale aware; and
4093 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004095- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4096 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4097 but with at least one decimal point and with a default precision
4098 of 12. Previously, the behavior the same but with a default precision of 6.
4099 This more closely matches ``str()``, and reduces surprises when adding
4100 alignment flags to the empty presentation type. This also affects the new
4101 complex.__format__ in the same way.
4102
4103- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00004284- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4285 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4286 instances. On a typical machine this saves 3 bytes of memory (on average) per
4287 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004289- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

4298
Georg Brandlba83f822010-03-14 09:50:54 +00004299- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4300 file objects with closefd=False. The file descriptor is still kept open but
4301 the file object behaves like a closed file. The ``FileIO`` object also got a
4302 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00004325- On windows, ``os.chdir()`` given unicode was not working if

4327 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00004330- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4331 element is temporarily replaced with an equivalent frozenset. But the
4332 eventual KeyError would always report the empty ``frozenset()`` as the missing
4333 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004353- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4354 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4355 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4356 of using the replace error handler in PyUnicode_DecodeUTF8().
4357
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004358- Issue #3739: The unicode-internal encoder now reports the number of characters

4360
Georg Brandlba83f822010-03-14 09:50:54 +00004361- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4362 allocator will be automatically disabled when running under Valgrind. This
4363 gives improved memory leak detection when running under Valgrind, while taking
4364 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005729- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5730
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005731- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5732 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5733 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5734 ``printf`` function, whereas PyString_FromFormat has an independent
5735 implementation and uses "%zd" on all platforms for size_t values.
5736 This makes a difference on win64, where ``printf`` needs "%Id" to display
5737 64bit values.
5738
Benjamin Peterson97179b02008-09-09 20:55:01 +00005739- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5743 object; previously an int would be returned for small values. the __long__
5744 method is allowed to return either an int or a long, but the behaviour of
5745 float objects should not change to respect backward compatibility.
5746
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005747- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00005753 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005754 was correctly parsed but parsing of subsequent arguments failed.
5755
Vinay Sajip35e3b032008-09-01 14:33:59 +00005756- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005757 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5758 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5759 when given a tuple of classes as second argument, were looking up
5760 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5761 type object.
5762
Neal Norwitz18aa3882008-08-24 05:04:52 +00005763- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005832 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5833 for catch_warnings() also led to an improvement in the raising of a

5906-----------------
5907
Guido van Rossumf8402962008-08-20 15:01:50 +00005908- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5909 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5910 extensions do not automatically benefit from the class attribute
5911 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5912 to their tp_flags field if they care. This is a backwards
5913 compatibility feature; in 3.0, all types will use the cache by
5914 default.
5915
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005916- Keyword arguments can now follow starred arguments. (``f(a, *args,
5917 keyword=23)`` is now valid syntax.)
5918
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005919- ctypes function pointers that are COM methods have a boolean True
5920 value again.
5921
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005922- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,

5930 ValueError consistently across platforms.
5931
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005932- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5933 (64bit Unix, for example), unichr() would truncate its argument and return
5934 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5935
Neal Norwitze7d8be82008-07-31 17:17:14 +00005936- Apply security patches from Apple.
5937
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005938- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

5940
Antoine Pitrou92f82162008-07-25 22:22:08 +00005941- Issue #1819: function calls with several named parameters are now on

Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005944- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5945 the python debugger steps into a class statement: the free variables (local
5946 variables defined in an outer scope) would be deleted from the outer scope.
5947
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005948- Issue #2620: Overflow checking when allocating or reallocating memory
5949 was not always being done properly in some python types and extension
5950 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5951 all been updated to perform better checks and places in the code that
5952 would previously leak memory on the error path when such an allocation
5953 failed have been fixed.

5959
Benjamin Petersone977ad42008-08-20 01:42:01 +00005960- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5961 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5962
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005963- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5964 version reported by these tools does not necessarily follow the python
5965 version numbering scheme, so the module is less strict when parsing it.
5966
Nick Coghlanf70385a2008-08-18 12:42:46 +00005967- Issue #2235: Added Py3k warnings for types which will become unhashable
5968 under the stricter __hash__ inheritance rules in 3.0. Several types
5969 which did not meet the rules for hash invariants and were already
5970 unhashable in 3.0 have now been explicitly flagged as unhashable in
5971 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5972 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5973
Brett Cannon88f801d2008-08-18 00:46:22 +00005974- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5975 imported into the module but exposed as part of the module's API.
5976

5996 after a 302 response in the case of not going through a proxy.
5997
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005998- Issue #2676: in the email package, content-type parsing was hanging on
5999 pathological input because of quadratic or exponential behaviour of a
6000 regular expression.
6001
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006002- Issue #3476: binary buffered reading through the new "io" library is now
6003 thread-safe.
6004
Brett Cannonbf3157b2008-08-14 05:00:03 +00006005- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6006 since mimetools itself is deprecated. Because modules are cached, all
6007 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6008
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006009- Issue #3134: shutil referenced undefined WindowsError symbol.

6012 menu entries were not deleted.
6013
Brett Cannon83e81842008-08-09 23:30:55 +00006014- Copied the implementation of reduce() to _functools.reduce() to have a

6016
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006017- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6018 a MemoryError rather than silently stop the iteration.
6019
Guido van Rossum59ce9012008-08-09 14:55:34 +00006020- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6021 to _sre.compile() will now be rejected. This should not affect anybody
6022 since the re.compile() function never generates invalid re-bytecode.
6023
Skip Montanaroa032bf42008-08-08 22:52:51 +00006024- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6025 upon first access it can be automatically initialized from the csv file if
6026 it wasn't initialized during instantiation.
6027
Brett Cannon3aa2a492008-08-06 22:28:09 +00006028- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6029 the reload() built-in has been removed.
6030
Brett Cannon7e30b672008-08-04 21:52:25 +00006031- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006032 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6040 raised an AttributeError.
6041
Benjamin Peterson01a24322008-07-28 23:35:27 +00006042- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006043 asking for a specific length. This problem only affected files opened
6044 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006069- Issue #3394: zipfile.writestr sets external attributes when passed a
6070 file name rather than a ZipInfo instance, so files are extracted with
6071 mode 0600 rather than 000 under Unix.
6072
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006073- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6074 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006085- Issue #2235: the C API function PyObject_HashNotImplemented and its
6086 interaction with the tp_hash slot (added in 2.6b2) are now documented
6087
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006088- Issue #643841: The language reference now provides more detailed
6089 coverage of the lookup process for special methods. The disclaimers
6090 regarding lack of coverage of new-style classes have also been
6091 removed, since the coverage is now fairly reasonable.

6095================================
6096
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006097*Release date: 17-Jul-2008*
6098
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006099Core and Builtins
6100-----------------
6101
Georg Brandl3e483f62008-07-16 22:57:41 +00006102- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6103 its methods now allow for items objects that can be converted to
6104 an integer using operator.index().
6105
Mark Dickinson64b7e502008-07-16 09:40:03 +00006106- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6107 produced a ValueError instead of giving the correct float.
6108
Eric Smitha5fa5a22008-07-16 00:11:49 +00006109- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6110 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6111
Mark Dickinson7103aa42008-07-15 19:08:33 +00006112- Issue #3008: the float type has a new instance method 'float.hex'
6113 and a new class method 'float.fromhex' to convert floating-point
6114 numbers to and from hexadecimal strings, respectively.
6115
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006116- Issue #2235: __hash__ is once again inherited by default. To allow
6117 collections.Hashable to remain meaningful in the presence of the
6118 default hash implementation (object.__hash__), it is now possible
6119 to explicit block inheritance of hash by setting __hash__=None at
6120 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6121 level.
6122
Nick Coghlanb028f502008-07-13 14:52:36 +00006123- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6124 the parent module cannot be found while performing an absolute import.
6125 This means that an incorrectly defined __package__ attribute will
6126 now only prevent relative imports in that module rather than causing
6127 all imports from that module to fail.
6128
Nick Coghlan14ff9942008-07-08 14:21:42 +00006129- Issue #2517: Allow unicode messages in Exceptions again by correctly
6130 bypassing the instance dictionary when looking up __unicode__ on
6131 new-style classes.
6132
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006133- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6134 set to a custom object whose write() method happens to install
6135 another file in sys.stdout.
6136
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006137- Issue #3088: Corrected a race condition in classes derived from
6138 threading.local: the first member set by a thread could be saved in
6139 another thread's dictionary.
6140
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006141- Issue #3004: Minor change to slice.indices(): the start and stop
6142 arguments are now treated identically, making the behaviour easier
6143 to describe and understand. For example, slice(None, -10,
6144 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6145 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6146 10, -1).
6147
Georg Brandl278fc502008-07-19 12:46:12 +00006148- Issue #3219: Calling a function with repeated keyword arguments,
6149 f(a=2, a=23), would not cause a syntax error. This was a regression
6150 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006151
Georg Brandl278fc502008-07-19 12:46:12 +00006152- Issue #2862: Make int and float freelist management consistent with
6153 other freelists. Changes their CompactFreeList apis into
6154 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006155

6157-------
6158
Thomas Heller57adf222008-08-14 19:10:48 +00006159- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6160 api functions without holding the GIL, which could lead to a fatal
6161 error when they failed.
6162
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006163- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006171- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6172 ForkingPickler.register() to resolve conflict with ctypes.
6173
Vinay Sajip51e65192008-07-18 09:01:10 +00006174- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006175
Thomas Heller880f5292008-07-15 19:39:38 +00006176- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6177 a valid dlerror() message.
6178
Thomas Heller2bad6572008-07-15 17:19:50 +00006179- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6180 incomplete structure was created.
6181

6185
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006186- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006187
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006188- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6189 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006190 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006191 content-length. The problem had been corrected in the 2.4 branch, but never
6192 merged into trunk.
6193
Georg Brandle78fbcc2008-07-05 10:13:36 +00006194- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00006202 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00006203
Vinay Sajip51e65192008-07-18 09:01:10 +00006204- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006205 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006206
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006207- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6208 handling is now the same as that of other special attributes like __name__).
6209
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006210- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6211 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00006600 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006601
6602 This is controlled by the configure argument ``--with-universal-archs``:
6603
6604 - ``--with-universal-archs=all``: install 4-way universal
6605
6606 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6607
6608 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6609
6610 This option should be used in combination with ``--enable-universalsdk=``.
6611
6612 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006662- Issue #1631171: Re-implement the 'warnings' module in C (the
6663 original Python code has been kept as backup). This will allow for
6664 using the 'warning's machinery in such places as the parser where
6665 use of pure Python code is not possible. Both the ``showarning()``
6666 and ``formatwarning()`` gain an optional 'line' argument which is
6667 not called by default for backwards-compatibility reasons. Setting
6668 ``warnings.showwarning()`` to an implementation that lacks support
6669 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006732- Issue #2550: The approach used by client/server code for obtaining
6733 ports to listen on in network-oriented tests has been refined in an
6734 effort to facilitate running multiple instances of the entire
6735 regression test suite in parallel without issue.
6736 test_support.bind_port() has been fixed such that it will always
6737 return a unique port -- which wasn't always the case with the
6738 previous implementation, especially if socket options had been set
6739 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6740 new implementation of bind_port() will actually raise an exception
6741 if it is passed an AF_INET/SOCK_STREAM socket with either the
6742 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6743 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6744 the socket it's been passed. This currently only applies to
6745 Windows. This option prevents any other sockets from binding to the
6746 host/port we've bound to, thus removing the possibility of the
6747 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6748 when a second SOCK_STREAM socket binds and accepts to a host/port
6749 that's already been bound by another socket. The optional preferred
6750 port parameter to bind_port() has been removed. Under no
6751 circumstances should tests be hard coding ports!
6752
6753 test_support.find_unused_port() has also been introduced, which will
6754 pass a temporary socket object to bind_port() in order to obtain an
6755 unused port. The temporary socket object is then closed and
6756 deleted, and the port is returned. This method should only be used
6757 for obtaining an unused port in order to pass to an external program
6758 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6759 a parameter to a server-oriented class that doesn't give you direct
6760 access to the underlying socket used.
6761
6762 Finally, test_support.HOST has been introduced, which should be used
6763 for the host argument of any relevant socket calls (i.e. bind and
6764 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006765
6766 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006767 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006768 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6769 test_asynchat and test_socket_ssl.
6770
Georg Brandl3ee81df2008-05-17 18:14:43 +00006771 It is now possible for multiple instances of the regression test
6772 suite to run in parallel without issue.

7039-----------------
7040
Fred Drakea8ee94b2008-03-01 02:45:07 +00007041- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007042 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007043
Georg Brandlad61bc82008-02-23 15:11:18 +00007044- Issue #2067: file.__exit__() now calls subclasses' close() method.
7045
7046- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007047
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007048- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007049 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007050
Eric Smitha73fbe72008-02-23 03:09:44 +00007051- Added the future_builtins module, which contains hex() and oct().
7052 These are the PEP 3127 version of these functions, designed to be
7053 compatible with the hex() and oct() builtins from Python 3.0. They
7054 differ slightly in their output formats from the existing, unchanged
7055 Python 2.6 builtins. The expected usage of the future_builtins
7056 module is:
7057 from future_builtins import hex, oct
7058
Eric Smith7ef40bf2008-02-20 23:34:22 +00007059- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7060 exponents for exponents with absolute value < 100. Follows C99
7061 standard. This is a change on Windows, which would use 3 digits.
7062 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7063 so that any alterations it does to the resulting string will be
7064 available in stringlib/formatter.h (for float.__format__).
7065
Eric Smith5a3c1352008-02-19 13:21:56 +00007066- Implemented PEP 3101, Advanced String Formatting. This adds a new
7067 builtin format(); a format() method for str and unicode; a
7068 __format__() method to object, str, unicode, int, long, float, and
7069 datetime; the class string.Formatter; and the C API
7070 PyObject_Format().
7071
Georg Brandl3ee81df2008-05-17 18:14:43 +00007072- Fixed several potential crashes, all caused by specially crafted
7073 __del__ methods exploiting objects in temporarily inconsistent
7074 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007075
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007076- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007077 prevent a possible crash: an Abstract Base Class would try to access
7078 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007079
Georg Brandl3ee81df2008-05-17 18:14:43 +00007080- Fixed repr() and str() of complex numbers with infinity or nan as
7081 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007082
Georg Brandl3ee81df2008-05-17 18:14:43 +00007083- Clear all free lists during a gc.collect() of the highest generation
7084 in order to allow pymalloc to free more arenas. Python may give back
7085 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007086
Georg Brandl3ee81df2008-05-17 18:14:43 +00007087- Issue #2045: Fix an infinite recursion triggered when printing a
7088 subclass of collections.defaultdict, if its default_factory is set
7089 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007090
Christian Heimesf75dbef2008-02-08 00:11:31 +00007091- Fixed a minor memory leak in dictobject.c. The content of the free
7092 list was not freed on interpreter shutdown.
7093
Georg Brandl21e99f42010-03-07 15:23:59 +00007094- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007095 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007096
Georg Brandl3ee81df2008-05-17 18:14:43 +00007097- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7098 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007099 to compact the internal free lists of pre-allocted ints and floats.
7100
Georg Brandl3ee81df2008-05-17 18:14:43 +00007101- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7102 calls. Python expected the return type int but the fork familie
7103 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007104
Georg Brandl3ee81df2008-05-17 18:14:43 +00007105- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7106 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007107
Georg Brandl3ee81df2008-05-17 18:14:43 +00007108- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7109 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007110
Georg Brandl3ee81df2008-05-17 18:14:43 +00007111- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7112 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007113
Georg Brandl3ee81df2008-05-17 18:14:43 +00007114- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7115 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007116
Georg Brandl3ee81df2008-05-17 18:14:43 +00007117- Patch #1473257: generator objects gain a gi_code attribute. This is
7118 the same object as the func_code attribute of the function that
7119 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007120
Georg Brandl3ee81df2008-05-17 18:14:43 +00007121- Issue #1920: "while 0" statements were completely removed by the
7122 compiler, even in the presence of an "else" clause, which is
7123 supposed to be run when the condition is false. Now the compiler
7124 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007125
Guido van Rossumeead05f2008-01-24 18:21:02 +00007126- A few crashers fixed: weakref_in_del.py (issue #1377858);
7127 loosing_dict_ref.py (issue #1303614, test67.py);
7128 borrowed_ref_[34].py (not in tracker).
7129
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007130- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007131 suppressed while an extension is loaded by calling SetErrorMode in
7132 dynload_win.c. The error is still reported properly.
7133
Georg Brandl3ee81df2008-05-17 18:14:43 +00007134- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007135 several extension methods and modules do not work without unicode
7136 support.
7137
Georg Brandl26543b12008-01-21 18:36:51 +00007138- Issue #1882: when compiling code from a string, encoding cookies in the
7139 second line of code were not always recognized correctly.
7140
Georg Brandl14404b62008-01-19 19:27:05 +00007141- Issue #1679: "0x" was taken as a valid integer literal.
7142
Georg Brandl6caad7d2008-01-26 14:19:22 +00007143- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007144 added.
7145
Christian Heimesc94e2b52008-01-14 04:13:37 +00007146- sys.float_info / PyFloat_GetInfo: The floating point information
7147 object was converted from a dict to a specialized structseq object.
7148
Georg Brandl3ee81df2008-05-17 18:14:43 +00007149- Patch #1816: Added sys.flags structseq. It exposes the status of
7150 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007151
Georg Brandl3ee81df2008-05-17 18:14:43 +00007152- Objects/structseq.c: Implemented new structseq representation. The
7153 patch makes structseqs (e.g. the return value of os.stat) more
7154 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007155
Georg Brandl3ee81df2008-05-17 18:14:43 +00007156- Patch #1700288: added a type attribute cache that caches method
7157 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007158
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007159- Bug #1776: __import__() no longer accepts filenames on any platform.
7160 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007161
Georg Brandlaed6c662008-01-07 17:25:53 +00007162- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7163
Georg Brandl3ee81df2008-05-17 18:14:43 +00007164- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7165 envvar and sys.dont_write_bytecode attribute. All these can be set
7166 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007167
Georg Brandl3ee81df2008-05-17 18:14:43 +00007168- Improve some exception messages when Windows fails to load an
7169 extension module. Now we get for example '%1 is not a valid Win32
7170 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007171
Georg Brandl3ee81df2008-05-17 18:14:43 +00007172- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007174- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7175 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007176
Christian Heimes0a8143f2007-12-18 23:22:54 +00007177- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007178 and INF. float("nan"), float("inf") and float("-inf") now work on
7179 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007180
Georg Brandl3ee81df2008-05-17 18:14:43 +00007181- Compiler now generates simpler and faster code for dictionary
7182 literals. The oparg for BUILD_MAP now indicates an estimated
7183 dictionary size. There is a new opcode, STORE_MAP, for adding
7184 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007185
Georg Brandl3ee81df2008-05-17 18:14:43 +00007186- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00007187
Georg Brandl3ee81df2008-05-17 18:14:43 +00007188- Issue #1620: New property decorator syntax was modifying the
7189 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00007190
Georg Brandl3ee81df2008-05-17 18:14:43 +00007191- Issue #1538: Avoid copying string in split/rsplit if the split char
7192 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007193
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007194- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007195 SystemError.
7196
Nick Coghlanef01d822007-12-03 12:55:17 +00007197- PEP 366: Allow explicit relative imports when executing modules
7198 inside packages with the -m switch via a new module level
7199 __package__ attribute.
7200
Georg Brandl3ee81df2008-05-17 18:14:43 +00007201- Issue #1402: Fix a crash on exit, when another thread is still
7202 running, and if the deallocation of its frames somehow calls the
7203 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007204

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007208 attribute of an empty cell object.
7209
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Issue #1460: The utf-7 incremental decoder did not accept truncated
7211 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007212
Georg Brandl3ee81df2008-05-17 18:14:43 +00007213- Patch #1739468: Directories and zipfiles containing a __main__.py
7214 file can now be directly executed by passing their name to the
7215 interpreter. The directory/zipfile is automatically inserted as the
7216 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007217
Georg Brandl3ee81df2008-05-17 18:14:43 +00007218- Issue #1265: Fix a problem with sys.settrace, if the tracing
7219 function uses a generator expression when at the same time the
7220 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007221
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007222- sets and frozensets now have an isdisjoint() method.
7223
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007224- optimize the performance of builtin.sum().
7225
Neal Norwitz44f326e2007-10-05 05:29:17 +00007226- Fix warnings found by the new version of the Coverity checker.
7227
Georg Brandl21e99f42010-03-07 15:23:59 +00007228- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007229 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7230 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007231
Georg Brandl3ee81df2008-05-17 18:14:43 +00007232- Issue #1686386: Tuple's tp_repr did not take into account the
7233 possibility of having a self-referential tuple, which is possible
7234 from C code. Nor did object's tp_str consider that a type's tp_str
7235 could do something that could lead to an inifinite recursion.
7236 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7237 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007238
Georg Brandl3ee81df2008-05-17 18:14:43 +00007239- Issue #1164: It was possible to trigger deadlock when using the
7240 'print' statement to write to a file since the GIL was not released
7241 as needed. Now PyObject_Print() does the right thing along with
7242 various tp_print implementations of the built-in types and those in
7243 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007244
Georg Brandl3ee81df2008-05-17 18:14:43 +00007245- Issue #1147: Exceptions were directly allowing string exceptions in
7246 their throw() method even though string exceptions no longer
7247 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007248
Georg Brandl3ee81df2008-05-17 18:14:43 +00007249- Issue #1096: Prevent a segfault from getting the repr of a very
7250 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007251
Brett Cannon1e534b52007-09-07 04:18:30 +00007252- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007253 PyObject_Call() never calling back out to Python code to trigger
7254 recursion depth updates/checks. Required the creation of a static
7255 RuntimeError instance in case normalizing an exception put the
7256 recursion check value past its limit. Fixes crashers
7257 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007258
Georg Brandl3ee81df2008-05-17 18:14:43 +00007259- Patch #1031213: Decode source line in SyntaxErrors back to its

7263 with %G.
7264
Georg Brandl3ee81df2008-05-17 18:14:43 +00007265- Prevent expandtabs() on string and unicode objects from causing a
7266 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007267
Georg Brandl3ee81df2008-05-17 18:14:43 +00007268- Issue #1733488: Fix compilation of bufferobject.c on AIX.
Martin v. Löwisda587ab2007-06-08 17:29:20 +00007269

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007276- Add -3 option to the interpreter to warn about features that are
7277 deprecated and will be changed/removed in Python 3.0.
7278
Georg Brandl2134e752007-05-21 20:34:16 +00007279- Patch #1686487: you can now pass any mapping after '**' in function
7280 calls.
7281
Collin Winter62903052007-05-18 23:11:24 +00007282- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007283 "except E as target:". This is to provide forwards compatibility
7284 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007285
Brett Cannon229cee22007-05-05 01:34:02 +00007286- Deprecate BaseException.message as per PEP 352.
7287
Georg Brandl3ee81df2008-05-17 18:14:43 +00007288- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007289 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007290
Vinay Sajip8549ce32007-05-06 17:53:37 +00007291- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007292 setting a plain string, ie don't expand to single letter identifiers.
7293
Raymond Hettinger13936692007-04-11 18:40:58 +00007294- Request #1191699: Slices can now be pickled.
7295
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007296- Request #1193128: str.translate() now allows a None argument for
7297 translations that only remove characters without re-mapping the
7298 remaining characters.
7299
Georg Brandl5cb76c12007-03-21 09:00:39 +00007300- Patch #1682205: a TypeError while unpacking an iterable is no longer
7301 masked by a generic one with the message "unpack non-sequence".
7302
Neal Norwitzaa754b72007-03-21 06:39:48 +00007303- Remove unused file Python/fmod.c.
7304
Guido van Rossum143b5642007-03-23 04:58:42 +00007305- Bug #1683368: The object.__init__() and object.__new__() methods are
7306 now stricter in rejecting excess arguments. The only time when
7307 either allows excess arguments is when it is not overridden and the
7308 other one is. For backwards compatibility, when both are
7309 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007310 warning later). Also, type.__init__() insists on the same signature
7311 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007312
Georg Brandl3ee81df2008-05-17 18:14:43 +00007313- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7314 object to complex using its __complex__() method before falling back
7315 to the __float__() method. Therefore, the functions in the cmath
7316 module now can operate on objects that define a __complex__()
7317 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007319- Patch #1623563: allow __class__ assignment for classes with
7320 __slots__. The old and the new class are still required to have the
7321 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007322

7327 ``object.__reduce_ex__()`` is called with an object that is faking
7328 its type.

7334
Georg Brandl7b9c5552007-03-12 14:30:05 +00007335- Bug #1678647: write a newline after printing an exception in any
7336 case, even when converting the value to a string failed.
7337
Georg Brandl871f1bc2007-03-12 13:17:36 +00007338- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007339 its argument, if it exists. If not, it will work like before. This
7340 allows customizing the output of dir() in the presence of a
7341 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007342
Collin Winter276887b2007-03-12 16:11:39 +00007343- Patch #922167: Python no longer segfaults when faced with infinitely
7344 self-recursive reload() calls (as reported by bug #742342).
7345
Georg Brandl3ee81df2008-05-17 18:14:43 +00007346- Patch #1675981: remove unreachable code from ``type.__new__()``
7347 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007349- Patch #1491866: change the complex() constructor to allow
7350 parthensized forms. This means complex(repr(x)) now works instead of
7351 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007352
Georg Brandlaa2321b2007-03-07 00:40:28 +00007353- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007354 makes the filenames the warning module prints much more sensible
7355 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007356
Georg Brandl49aafc92007-03-07 00:34:46 +00007357- Variant of patch #697613: don't exit the interpreter on a SystemExit
7358 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007359 variable is given, but break into the interactive interpreter just
7360 like on other exceptions or normal program exit.

7366 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00007367
Georg Brandl0fca97a2007-03-05 22:28:08 +00007368- Patch #1674228: when assigning a slice (old-style), check for the
7369 sq_ass_slice instead of the sq_slice slot.
7370
Georg Brandl3ee81df2008-05-17 18:14:43 +00007371- When printing an unraisable error, don't print exceptions. before
7372 the name. This duplicates the behavior whening normally printing
7373 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00007374
Georg Brandl3ee81df2008-05-17 18:14:43 +00007375- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00007381- Bug #1377858: Fix the segfaulting of the interpreter when an object
7382 created a weakref on itself during a __del__ call for new-style
7383 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00007384
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00007385- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

Georg Brandl2c1375c2006-10-12 11:27:59 +00007423- Bug #1545497: when given an explicit base, int() did ignore NULs
7424 embedded in the string to convert.
7425
Georg Brandl846f73a2006-10-08 07:11:54 +00007426- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007474 generator expressions (x for x, in ... ) works again. Fixing this
7475 problem required changing the .pyc magic number. This means that
7476 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007906 AttributeError instead of an IOError when the server's response
7907 didn't contain a valid HTTP status line.

7998 TestCase and TestSuite subclasses (not instances) are no longer
7999 accepted in TestSuite.addTest(). This should cause no
8000 incompatibility since it never made sense with ordinary subclasses
8001 -- the failure just occurred later, with a more cumbersome
8002 exception.

8281 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008282
Georg Brandl3ee81df2008-05-17 18:14:43 +00008283- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8284 with RFC 3207 and forgets any knowledge obtained from the server not
8285 obtained from the TLS negotiation itself. Patch contributed by Bill
8286 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008287
Georg Brandl3ee81df2008-05-17 18:14:43 +00008288- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008289 that the SMTP.starttls() caller no longer needs to call ehlo()
8290 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008291 does not claim to support starttls. Adds the
8292 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8373 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8374 silently miscode subclasses of those types. Now, it raises a
8375 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008376

Georg Brandl3ee81df2008-05-17 18:14:43 +00008391 time so that opening a database previously created with the DB_DUP
8392 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8393 opens. Specifically: dictionary assignment to a DB object will
8394 replace all values for a given key when the database allows
8395 duplicate values. DB users should use DB.put(k, v) when they want
8396 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008397

8403 characters with ASCII value less than 32. Also, it correctly quotes
8404 dots only if they occur on a single line, as opposed to the previous
8405 behavior of quoting dots if they are the second character of any
8406 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008407

Georg Brandl3ee81df2008-05-17 18:14:43 +00008742- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8743 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8744 PyLong_FromSsize_t public functions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008751- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8752 of w# format code incorrectly truncated the length to an int, even
8753 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8754 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008755
Georg Brandl3ee81df2008-05-17 18:14:43 +00008756- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8774- Fix some leftovers from the conversion from int to Py_ssize_t
8775 (relevant to strings and sequences of more than 2**31 items).
8776
8777- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8778 outside of pystate.c and should not be necessary.
8779
Georg Brandl3ee81df2008-05-17 18:14:43 +00008780- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

Georg Brandl3ee81df2008-05-17 18:14:43 +00008784- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8785 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008786
Georg Brandl3ee81df2008-05-17 18:14:43 +00008787- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008794- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8795 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8796 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8797 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008798

Georg Brandl3ee81df2008-05-17 18:14:43 +00008812- Removed the macfs module. It had been deprecated since Python 2.5.
8813 This lead to the deprecation of macostools.touched() as it relied
8814 solely on macfs and was a no-op under OS X.
