Antoine Pitrou5b4b2da2011-12-15 14:15:31 +0100600- Fix the fix for issue #12149: it was incorrect, although it had the side

633
Mark Dickinsondbbed042011-09-19 16:38:08 +0100634- Issue #12973: Fix overflow checks that invoked undefined behaviour in
635 int.__pow__. These overflow checks were causing int.__pow__ to produce
636 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100637 compiler optimizing the check away. Also fix similar overflow checks
638 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
639 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +0200650- Issue #12149: Update the method cache after a type's dictionnary gets
651 cleared by the garbage collector. This fixes a segfault when an instance
652 and its type get caught in a reference cycle, and the instance's
653 deallocator calls one of the methods on the type (e.g. when subclassing
654 IOBase). Diagnosis and patch by Davide Rizzo.

Victor Stinner08563d92011-05-30 23:44:13 +0200663 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
664 raw_input() interrupted by CTRL+c.
665
Łukasz Langa7a153902011-10-18 17:16:00 +0200666- Issue #10860: httplib now correctly handles an empty port after port

Florent Xiclunac2279652012-02-12 14:49:03 +0100707- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100708 has left two versions of customize_compiler, the original in
709 distutils.sysconfig and another copy in distutils.ccompiler, with some
710 parts of distutils calling one and others using the other.

712 is the case in 3.x.
713
Ned Deily0d0ea482012-02-10 12:59:06 +0100714- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
715 Distutils-based packages with C extension modules may fail because
716 Apple has removed gcc-4.2, the version used to build python.org
717 64-bit/32-bit Pythons. If the user does not explicitly override
718 the default C compiler by setting the CC environment variable,
719 Distutils will now attempt to compile extension modules with clang
720 if gcc-4.2 is required but not found. Also as a convenience, if
721 the user does explicitly set CC, substitute its value as the default
722 compiler in the Distutils LDSHARED configuration variable for OS X.
723 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
724 SDK, neither of which are available in Xcode 4. This change does not
725 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700998- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
999 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1000 interpreter process. This could cause failures in non-Distutils subprocesses
1001 and was unreliable since tests or user programs could modify the interpreter
1002 environment after Distutils set it. Instead, have Distutils set the the
1003 deployment target only in the environment of each build subprocess. It is
1004 still possible to globally override the default by setting
1005 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1006 greater or equal to the default value, the value with which the interpreter
1007 was built.

1036 updating the check interval, so if the user decreases the check interval,
1037 the ticker doesn't have to wind down to zero from the old starting point
1038 before the new interval takes effect. And if the user increases the
1039 interval, it makes sure the new limit takes effect right away rather have an
1040 early task switch before recognizing the new interval.

1992 This prevents user-created self-referencing ordered dictionaries from
1993 becoming permanently uncollectable GC garbage. The downside is that
1994 removing __del__ means that the internal doubly-linked list has to wait for
1995 GC collection rather than freeing memory immediately when the refcnt drops
1996 to zero.

2004 to fetch the original errno, or to filter timeout errors. Now the
2005 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002455- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2456 start byte and the continuation byte(s) are now considered invalid, instead
2457 of the number of bytes specified by the start byte.
2458 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2459 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2460 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002469- Issue #8748: Fix two issues with comparisons between complex and integer
2470 objects. (1) The comparison could incorrectly return True in some cases
2471 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2472 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00002613- Issue #1533: Fix inconsistency in range function argument processing: any
2614 non-float non-integer argument is now converted to an integer (if possible)
2615 using its __int__ method. Previously, only small arguments were treated this
2616 way; larger arguments (those whose __int__ was outside the range of a C long)
2617 would produce a TypeError.

2668 operation raises multiple signals and more than one of those signals is
2669 trapped, the specification determines the order in which the signals should be

Georg Brandlfee0f442010-05-22 21:26:21 +00002846- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002847 on 64-bit machines. The shift count for either left or right shift is
2848 permitted to be up to sys.maxsize.
2849
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002850- Ensure that tokenization of identifiers is not affected by locale.
2851
Georg Brandlfee0f442010-05-22 21:26:21 +00002852- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002853
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002854- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2855
Georg Brandlfee0f442010-05-22 21:26:21 +00002856- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2857 with a non-empty format string. This is an effort to future-proof user
2858 code. If a derived class does not currently implement __format__ but later
2859 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002860 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002861 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002862
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002863- Issue #8268: Old-style classes (not just instances) now support weak
2864 references.

Victor Stinner66644262010-03-10 22:30:19 +00002876- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002877 (SIGINT). If an error occurs while importing the site module, the error is
2878 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002879 module.

2893
Georg Brandlfee0f442010-05-22 21:26:21 +00002894- Issue #8257: The Decimal construct now accepts a float instance directly,
2895 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002896
2897 >>> Decimal(1.1)
2898 Decimal('1.100000000000000088817841970012523233890533447265625')
2899
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002900- collections.Counter() now supports a subtract() method.
2901
Georg Brandlfee0f442010-05-22 21:26:21 +00002902- The functools module now has a total_ordering() class decorator to simplify
2903 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002905- The functools module also adds cmp_to_key() as a tool to transition old-style
2906 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002907
Georg Brandlfee0f442010-05-22 21:26:21 +00002908- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2909 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002910
Georg Brandlfee0f442010-05-22 21:26:21 +00002911- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2912 InvalidOperation instead of returning False. (Comparisons involving a quiet
2913 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2914 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002915
Georg Brandlfee0f442010-05-22 21:26:21 +00002916- Issue #2531: Comparison operations between floats and Decimal instances now
2917 return a result based on the numeric values of the operands; previously they
2918 returned an arbitrary result based on the relative ordering of id(float) and
2919 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002920
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002921- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002922 argument `-` which tells it to read files to compile from stdin. Each line is
2923 read on demand and the named file is compiled immediately. (Original patch by
2924 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002925
Georg Brandlfee0f442010-05-22 21:26:21 +00002926- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002929- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2930 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002931 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002932
Georg Brandlfee0f442010-05-22 21:26:21 +00002933- Comparisons using one of <, <=, >, >= between a complex instance and a
2934 Fractions instance now raise TypeError instead of returning True/False. This
2935 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2936 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002937

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002947- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002948 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2949 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002950
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002951- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2952 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00002992 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2993 log file to compute the next rollover time. If the log file does not exist,
2994 the current time is used as the basis for the computation.

Georg Brandlba83f822010-03-14 09:50:54 +00003004- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3005 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3006 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003035- Issue #8300: When passing a non-integer argument to struct.pack with any
3036 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlfee0f442010-05-22 21:26:21 +00003043 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was

3045 the set of integer codes for which it was used differed between native packing
3046 and standard packing.)

Mark Dickinson8efef5c2010-01-12 22:23:56 +00003309
Georg Brandlba83f822010-03-14 09:50:54 +00003310 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
3311 strings,
3312 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3313 numeric strings corresponding to subnormal values,
3314 (3) a memory leak for some values large enough to cause overflow, and
3315 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00003354 file position when calling `truncate()`. It would previously change the file
3355 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003356 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

3359 class used to represent files stored inside an archive. The new
3360 implementation is significantly faster and can be wrapped in a
3361 ``io.BufferedReader`` object for more speedups. It also solves an issue
3362 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3375 encoded string for them. This ensures that the upload and register commands
3376 send the correct values to PyPI without any error.

3450Core and Builtins
3451-----------------
3452
Georg Brandlba83f822010-03-14 09:50:54 +00003453- The ``__complex__()`` method is now looked up on the class of instances to
3454 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003456- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3457 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3458
Mark Dickinson1b34d252010-01-01 17:27:30 +00003459- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003460 DeprecationWarning when passed a float argument where an integer was expected.
3461 These functions and methods now raise TypeError instead. The majority of the
3462 effects of this change are in the extension modules, but some core functions
3463 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3464 and many unicode/str methods.

3475 used to drop the time part of the result.
3476
Georg Brandlba83f822010-03-14 09:50:54 +00003477- Issue #1811: Improve accuracy and cross-platform consistency for true division
3478 of integers: the result of a/b is now correctly rounded for ints a and b (at
3479 least on IEEE 754 platforms), and in particular does not depend on the
3480 internal representation of a long.

3488
Georg Brandlba83f822010-03-14 09:50:54 +00003489 These executables now work properly with the arch(1) command: ``arch -ppc
3490 python`` will start a universal binary version of python in PPC mode (unlike

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003632

Georg Brandlba83f822010-03-14 09:50:54 +00003647- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3648 decimal string that's guaranteed to round back to x under correct rounding
3649 (with round-half-to-even rounding mode). Previously it gave a string based on
3650 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3651 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3652 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003653
Georg Brandlba83f822010-03-14 09:50:54 +00003654- Issue #7117: On almost all platforms: float-to-string and string-to-float
3655 conversions within Python are now correctly rounded. Places these conversions
3656 occur include: str for floats and complex numbers; the float and complex
3657 constructors; old-style and new-style numeric formatting; serialization and
3658 deserialization of floats and complex numbers using marshal, pickle and json;
3659 parsing of float and imaginary literals in Python code; Decimal-to-float
3660 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003661
Georg Brandlba83f822010-03-14 09:50:54 +00003662 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3663 providing correctly-rounded strtod and dtoa C functions. This code is
3664 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3665 the C compiler. There may be a small number of platforms on which correct
3666 operation of this code cannot be guaranteed, so the code is not used: notably,
3667 this applies to platforms where the C double format is not IEEE 754 binary64,
3668 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3669 and Python's configure script is unable to determine how to change the FPU
3670 precision. On these platforms conversions use the platform strtod and dtoa,
3671 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003673- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3674 uses the correctly-rounded string <-> float conversions described above (when
3675 available), and so produces correctly rounded results that will display nicely
3676 under the float repr. There are two related small changes: (1) round now
3677 accepts any class with an ``__index__()`` method for its second argument (but
3678 no longer accepts floats for the second argument), and (2) an excessively
3679 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3680 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003823 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3824 (2) parsing of strings representing infinities and nans was locale aware; and
3825 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003827- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3828 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3829 but with at least one decimal point and with a default precision
3830 of 12. Previously, the behavior the same but with a default precision of 6.
3831 This more closely matches ``str()``, and reduces surprises when adding
3832 alignment flags to the empty presentation type. This also affects the new
3833 complex.__format__ in the same way.
3834
3835- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00004016- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4017 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4018 instances. On a typical machine this saves 3 bytes of memory (on average) per
4019 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004021- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

4030
Georg Brandlba83f822010-03-14 09:50:54 +00004031- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4032 file objects with closefd=False. The file descriptor is still kept open but
4033 the file object behaves like a closed file. The ``FileIO`` object also got a
4034 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00004057- On windows, ``os.chdir()`` given unicode was not working if

4059 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00004062- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4063 element is temporarily replaced with an equivalent frozenset. But the
4064 eventual KeyError would always report the empty ``frozenset()`` as the missing
4065 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004085- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4086 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4087 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4088 of using the replace error handler in PyUnicode_DecodeUTF8().
4089
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004090- Issue #3739: The unicode-internal encoder now reports the number of characters

4092
Georg Brandlba83f822010-03-14 09:50:54 +00004093- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4094 allocator will be automatically disabled when running under Valgrind. This
4095 gives improved memory leak detection when running under Valgrind, while taking
4096 advantage of pymalloc at other times.

5262 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5263 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5264 neither __int__ nor __long__, TypeError used to be raised (with a
5265 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5266 struct.error in other cases.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005461- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5462
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005463- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5464 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5465 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5466 ``printf`` function, whereas PyString_FromFormat has an independent
5467 implementation and uses "%zd" on all platforms for size_t values.
5468 This makes a difference on win64, where ``printf`` needs "%Id" to display
5469 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005471- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5475 object; previously an int would be returned for small values. the __long__
5476 method is allowed to return either an int or a long, but the behaviour of
5477 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005479- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00005485 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005486 was correctly parsed but parsing of subsequent arguments failed.
5487
Vinay Sajip35e3b032008-09-01 14:33:59 +00005488- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005489 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5490 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5491 when given a tuple of classes as second argument, were looking up
5492 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5493 type object.
5494

5638-----------------
5639
Guido van Rossumf8402962008-08-20 15:01:50 +00005640- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5641 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5642 extensions do not automatically benefit from the class attribute
5643 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5644 to their tp_flags field if they care. This is a backwards
5645 compatibility feature; in 3.0, all types will use the cache by
5646 default.
5647
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005648- Keyword arguments can now follow starred arguments. (``f(a, *args,
5649 keyword=23)`` is now valid syntax.)
5650
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005651- ctypes function pointers that are COM methods have a boolean True
5652 value again.

Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005664- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5665 (64bit Unix, for example), unichr() would truncate its argument and return
5666 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005676- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5677 the python debugger steps into a class statement: the free variables (local
5678 variables defined in an outer scope) would be deleted from the outer scope.
5679
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005680- Issue #2620: Overflow checking when allocating or reallocating memory
5681 was not always being done properly in some python types and extension
5682 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5683 all been updated to perform better checks and places in the code that
5684 would previously leak memory on the error path when such an allocation
5685 failed have been fixed.

5691
Benjamin Petersone977ad42008-08-20 01:42:01 +00005692- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5693 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5694
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005695- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5696 version reported by these tools does not necessarily follow the python
5697 version numbering scheme, so the module is less strict when parsing it.
5698
Nick Coghlanf70385a2008-08-18 12:42:46 +00005699- Issue #2235: Added Py3k warnings for types which will become unhashable
5700 under the stricter __hash__ inheritance rules in 3.0. Several types
5701 which did not meet the rules for hash invariants and were already
5702 unhashable in 3.0 have now been explicitly flagged as unhashable in
5703 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5704 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5705
Brett Cannon88f801d2008-08-18 00:46:22 +00005706- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5707 imported into the module but exposed as part of the module's API.
5708

5732 regular expression.
5733
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005734- Issue #3476: binary buffered reading through the new "io" library is now
5735 thread-safe.

Brett Cannonbf3157b2008-08-14 05:00:03 +00005737- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5738 since mimetools itself is deprecated. Because modules are cached, all
5739 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5740
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005741- Issue #3134: shutil referenced undefined WindowsError symbol.

5750 a MemoryError rather than silently stop the iteration.
5751
Guido van Rossum59ce9012008-08-09 14:55:34 +00005752- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5753 to _sre.compile() will now be rejected. This should not affect anybody
5754 since the re.compile() function never generates invalid re-bytecode.
5755
Skip Montanaroa032bf42008-08-08 22:52:51 +00005756- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5757 upon first access it can be automatically initialized from the csv file if
5758 it wasn't initialized during instantiation.
5759
Brett Cannon3aa2a492008-08-06 22:28:09 +00005760- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5761 the reload() built-in has been removed.
5762
Brett Cannon7e30b672008-08-04 21:52:25 +00005763- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005764 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5772 raised an AttributeError.
5773

Antoine Pitroude781a42008-08-09 12:43:23 +00005775 asking for a specific length. This problem only affected files opened
5776 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005801- Issue #3394: zipfile.writestr sets external attributes when passed a
5802 file name rather than a ZipInfo instance, so files are extracted with
5803 mode 0600 rather than 000 under Unix.
5804
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005805- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5806 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005817- Issue #2235: the C API function PyObject_HashNotImplemented and its
5818 interaction with the tp_hash slot (added in 2.6b2) are now documented
5819
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005820- Issue #643841: The language reference now provides more detailed
5821 coverage of the lookup process for special methods. The disclaimers
5822 regarding lack of coverage of new-style classes have also been
5823 removed, since the coverage is now fairly reasonable.

5827================================
5828
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005829*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005831Core and Builtins
5832-----------------
5833
Georg Brandl3e483f62008-07-16 22:57:41 +00005834- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5835 its methods now allow for items objects that can be converted to
5836 an integer using operator.index().
5837
Mark Dickinson64b7e502008-07-16 09:40:03 +00005838- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5839 produced a ValueError instead of giving the correct float.
5840
Eric Smitha5fa5a22008-07-16 00:11:49 +00005841- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5842 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5843
Mark Dickinson7103aa42008-07-15 19:08:33 +00005844- Issue #3008: the float type has a new instance method 'float.hex'
5845 and a new class method 'float.fromhex' to convert floating-point
5846 numbers to and from hexadecimal strings, respectively.
5847
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005848- Issue #2235: __hash__ is once again inherited by default. To allow
5849 collections.Hashable to remain meaningful in the presence of the
5850 default hash implementation (object.__hash__), it is now possible
5851 to explicit block inheritance of hash by setting __hash__=None at
5852 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5853 level.
5854
Nick Coghlanb028f502008-07-13 14:52:36 +00005855- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5856 the parent module cannot be found while performing an absolute import.
5857 This means that an incorrectly defined __package__ attribute will
5858 now only prevent relative imports in that module rather than causing
5859 all imports from that module to fail.
5860
Nick Coghlan14ff9942008-07-08 14:21:42 +00005861- Issue #2517: Allow unicode messages in Exceptions again by correctly
5862 bypassing the instance dictionary when looking up __unicode__ on
5863 new-style classes.
5864
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005865- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5866 set to a custom object whose write() method happens to install
5867 another file in sys.stdout.
5868
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005869- Issue #3088: Corrected a race condition in classes derived from
5870 threading.local: the first member set by a thread could be saved in
5871 another thread's dictionary.
5872
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005873- Issue #3004: Minor change to slice.indices(): the start and stop
5874 arguments are now treated identically, making the behaviour easier
5875 to describe and understand. For example, slice(None, -10,
5876 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5877 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5878 10, -1).
5879
Georg Brandl278fc502008-07-19 12:46:12 +00005880- Issue #3219: Calling a function with repeated keyword arguments,
5881 f(a=2, a=23), would not cause a syntax error. This was a regression
5882 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005883
Georg Brandl278fc502008-07-19 12:46:12 +00005884- Issue #2862: Make int and float freelist management consistent with
5885 other freelists. Changes their CompactFreeList apis into
5886 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00005891- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5892 api functions without holding the GIL, which could lead to a fatal
5893 error when they failed.
5894
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005895- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005903- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5904 ForkingPickler.register() to resolve conflict with ctypes.
5905
Vinay Sajip51e65192008-07-18 09:01:10 +00005906- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00005908- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5909 a valid dlerror() message.
5910
Thomas Heller2bad6572008-07-15 17:19:50 +00005911- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5912 incomplete structure was created.
5913

5917
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005918- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005919
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005920- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5921 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005922 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005923 content-length. The problem had been corrected in the 2.4 branch, but never
5924 merged into trunk.
5925
Georg Brandle78fbcc2008-07-05 10:13:36 +00005926- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005937 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005938
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005939- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5940 handling is now the same as that of other special attributes like __name__).
5941
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005942- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5943 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00006332 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006333
6334 This is controlled by the configure argument ``--with-universal-archs``:
6335
6336 - ``--with-universal-archs=all``: install 4-way universal
6337
6338 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6339
6340 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6341
6342 This option should be used in combination with ``--enable-universalsdk=``.
6343
6344 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 +00006394- Issue #1631171: Re-implement the 'warnings' module in C (the
6395 original Python code has been kept as backup). This will allow for
6396 using the 'warning's machinery in such places as the parser where
6397 use of pure Python code is not possible. Both the ``showarning()``
6398 and ``formatwarning()`` gain an optional 'line' argument which is
6399 not called by default for backwards-compatibility reasons. Setting
6400 ``warnings.showwarning()`` to an implementation that lacks support
6401 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006464- Issue #2550: The approach used by client/server code for obtaining
6465 ports to listen on in network-oriented tests has been refined in an
6466 effort to facilitate running multiple instances of the entire
6467 regression test suite in parallel without issue.
6468 test_support.bind_port() has been fixed such that it will always
6469 return a unique port -- which wasn't always the case with the
6470 previous implementation, especially if socket options had been set
6471 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6472 new implementation of bind_port() will actually raise an exception
6473 if it is passed an AF_INET/SOCK_STREAM socket with either the
6474 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6475 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6476 the socket it's been passed. This currently only applies to
6477 Windows. This option prevents any other sockets from binding to the
6478 host/port we've bound to, thus removing the possibility of the
6479 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6480 when a second SOCK_STREAM socket binds and accepts to a host/port
6481 that's already been bound by another socket. The optional preferred
6482 port parameter to bind_port() has been removed. Under no
6483 circumstances should tests be hard coding ports!
6484
6485 test_support.find_unused_port() has also been introduced, which will
6486 pass a temporary socket object to bind_port() in order to obtain an
6487 unused port. The temporary socket object is then closed and
6488 deleted, and the port is returned. This method should only be used
6489 for obtaining an unused port in order to pass to an external program
6490 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6491 a parameter to a server-oriented class that doesn't give you direct
6492 access to the underlying socket used.
6493
6494 Finally, test_support.HOST has been introduced, which should be used
6495 for the host argument of any relevant socket calls (i.e. bind and
6496 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006497
6498 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006499 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

6770Core and builtins
6771-----------------
6772
Fred Drakea8ee94b2008-03-01 02:45:07 +00006773- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006774 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006775
Georg Brandlad61bc82008-02-23 15:11:18 +00006776- Issue #2067: file.__exit__() now calls subclasses' close() method.
6777
6778- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006779
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006780- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006781 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006782
Eric Smitha73fbe72008-02-23 03:09:44 +00006783- Added the future_builtins module, which contains hex() and oct().
6784 These are the PEP 3127 version of these functions, designed to be
6785 compatible with the hex() and oct() builtins from Python 3.0. They
6786 differ slightly in their output formats from the existing, unchanged
6787 Python 2.6 builtins. The expected usage of the future_builtins
6788 module is:
6789 from future_builtins import hex, oct
6790
Eric Smith7ef40bf2008-02-20 23:34:22 +00006791- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6792 exponents for exponents with absolute value < 100. Follows C99
6793 standard. This is a change on Windows, which would use 3 digits.
6794 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6795 so that any alterations it does to the resulting string will be
6796 available in stringlib/formatter.h (for float.__format__).
6797
Eric Smith5a3c1352008-02-19 13:21:56 +00006798- Implemented PEP 3101, Advanced String Formatting. This adds a new
6799 builtin format(); a format() method for str and unicode; a
6800 __format__() method to object, str, unicode, int, long, float, and
6801 datetime; the class string.Formatter; and the C API
6802 PyObject_Format().
6803
Georg Brandl3ee81df2008-05-17 18:14:43 +00006804- Fixed several potential crashes, all caused by specially crafted
6805 __del__ methods exploiting objects in temporarily inconsistent
6806 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006807
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006808- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006809 prevent a possible crash: an Abstract Base Class would try to access
6810 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006811
Georg Brandl3ee81df2008-05-17 18:14:43 +00006812- Fixed repr() and str() of complex numbers with infinity or nan as
6813 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006814
Georg Brandl3ee81df2008-05-17 18:14:43 +00006815- Clear all free lists during a gc.collect() of the highest generation
6816 in order to allow pymalloc to free more arenas. Python may give back
6817 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006818
Georg Brandl3ee81df2008-05-17 18:14:43 +00006819- Issue #2045: Fix an infinite recursion triggered when printing a
6820 subclass of collections.defaultdict, if its default_factory is set
6821 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006822
Christian Heimesf75dbef2008-02-08 00:11:31 +00006823- Fixed a minor memory leak in dictobject.c. The content of the free
6824 list was not freed on interpreter shutdown.
6825
Georg Brandl21e99f42010-03-07 15:23:59 +00006826- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006827 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006828
Georg Brandl3ee81df2008-05-17 18:14:43 +00006829- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6830 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006831 to compact the internal free lists of pre-allocted ints and floats.
6832
Georg Brandl3ee81df2008-05-17 18:14:43 +00006833- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6834 calls. Python expected the return type int but the fork familie
6835 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006836
Georg Brandl3ee81df2008-05-17 18:14:43 +00006837- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6838 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006839
Georg Brandl3ee81df2008-05-17 18:14:43 +00006840- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6841 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006842
Georg Brandl3ee81df2008-05-17 18:14:43 +00006843- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6844 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006845
Georg Brandl3ee81df2008-05-17 18:14:43 +00006846- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6847 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006848
Georg Brandl3ee81df2008-05-17 18:14:43 +00006849- Patch #1473257: generator objects gain a gi_code attribute. This is
6850 the same object as the func_code attribute of the function that
6851 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006852
Georg Brandl3ee81df2008-05-17 18:14:43 +00006853- Issue #1920: "while 0" statements were completely removed by the
6854 compiler, even in the presence of an "else" clause, which is
6855 supposed to be run when the condition is false. Now the compiler
6856 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006857
Guido van Rossumeead05f2008-01-24 18:21:02 +00006858- A few crashers fixed: weakref_in_del.py (issue #1377858);
6859 loosing_dict_ref.py (issue #1303614, test67.py);
6860 borrowed_ref_[34].py (not in tracker).
6861
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006862- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006863 suppressed while an extension is loaded by calling SetErrorMode in
6864 dynload_win.c. The error is still reported properly.
6865
Georg Brandl3ee81df2008-05-17 18:14:43 +00006866- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006867 several extension methods and modules do not work without unicode
6868 support.
6869
Georg Brandl26543b12008-01-21 18:36:51 +00006870- Issue #1882: when compiling code from a string, encoding cookies in the
6871 second line of code were not always recognized correctly.
6872
Georg Brandl14404b62008-01-19 19:27:05 +00006873- Issue #1679: "0x" was taken as a valid integer literal.
6874
Georg Brandl6caad7d2008-01-26 14:19:22 +00006875- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006876 added.
6877
Christian Heimesc94e2b52008-01-14 04:13:37 +00006878- sys.float_info / PyFloat_GetInfo: The floating point information
6879 object was converted from a dict to a specialized structseq object.
6880
Georg Brandl3ee81df2008-05-17 18:14:43 +00006881- Patch #1816: Added sys.flags structseq. It exposes the status of
6882 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006883
Georg Brandl3ee81df2008-05-17 18:14:43 +00006884- Objects/structseq.c: Implemented new structseq representation. The
6885 patch makes structseqs (e.g. the return value of os.stat) more
6886 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006887
Georg Brandl3ee81df2008-05-17 18:14:43 +00006888- Patch #1700288: added a type attribute cache that caches method
6889 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006890
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006891- Bug #1776: __import__() no longer accepts filenames on any platform.
6892 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006893
Georg Brandlaed6c662008-01-07 17:25:53 +00006894- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6895
Georg Brandl3ee81df2008-05-17 18:14:43 +00006896- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6897 envvar and sys.dont_write_bytecode attribute. All these can be set
6898 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006899
Georg Brandl3ee81df2008-05-17 18:14:43 +00006900- Improve some exception messages when Windows fails to load an
6901 extension module. Now we get for example '%1 is not a valid Win32
6902 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006903
Georg Brandl3ee81df2008-05-17 18:14:43 +00006904- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00006905
Georg Brandl3ee81df2008-05-17 18:14:43 +00006906- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6907 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006908
Christian Heimes0a8143f2007-12-18 23:22:54 +00006909- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006910 and INF. float("nan"), float("inf") and float("-inf") now work on
6911 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006912
Georg Brandl3ee81df2008-05-17 18:14:43 +00006913- Compiler now generates simpler and faster code for dictionary
6914 literals. The oparg for BUILD_MAP now indicates an estimated
6915 dictionary size. There is a new opcode, STORE_MAP, for adding
6916 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006917
Georg Brandl3ee81df2008-05-17 18:14:43 +00006918- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00006919
Georg Brandl3ee81df2008-05-17 18:14:43 +00006920- Issue #1620: New property decorator syntax was modifying the
6921 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006922
Georg Brandl3ee81df2008-05-17 18:14:43 +00006923- Issue #1538: Avoid copying string in split/rsplit if the split char
6924 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006925
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006926- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006927 SystemError.
6928
Nick Coghlanef01d822007-12-03 12:55:17 +00006929- PEP 366: Allow explicit relative imports when executing modules
6930 inside packages with the -m switch via a new module level
6931 __package__ attribute.
6932
Georg Brandl3ee81df2008-05-17 18:14:43 +00006933- Issue #1402: Fix a crash on exit, when another thread is still
6934 running, and if the deallocation of its frames somehow calls the
6935 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006936

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006940 attribute of an empty cell object.
6941
Georg Brandl3ee81df2008-05-17 18:14:43 +00006942- Issue #1460: The utf-7 incremental decoder did not accept truncated
6943 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006944
Georg Brandl3ee81df2008-05-17 18:14:43 +00006945- Patch #1739468: Directories and zipfiles containing a __main__.py
6946 file can now be directly executed by passing their name to the
6947 interpreter. The directory/zipfile is automatically inserted as the
6948 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006949
Georg Brandl3ee81df2008-05-17 18:14:43 +00006950- Issue #1265: Fix a problem with sys.settrace, if the tracing
6951 function uses a generator expression when at the same time the
6952 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006953
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006954- sets and frozensets now have an isdisjoint() method.
6955
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006956- optimize the performance of builtin.sum().
6957
Neal Norwitz44f326e2007-10-05 05:29:17 +00006958- Fix warnings found by the new version of the Coverity checker.
6959
Georg Brandl21e99f42010-03-07 15:23:59 +00006960- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006961 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6962 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006963
Georg Brandl3ee81df2008-05-17 18:14:43 +00006964- Issue #1686386: Tuple's tp_repr did not take into account the
6965 possibility of having a self-referential tuple, which is possible
6966 from C code. Nor did object's tp_str consider that a type's tp_str
6967 could do something that could lead to an inifinite recursion.
6968 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6969 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006970
Georg Brandl3ee81df2008-05-17 18:14:43 +00006971- Issue #1164: It was possible to trigger deadlock when using the
6972 'print' statement to write to a file since the GIL was not released
6973 as needed. Now PyObject_Print() does the right thing along with
6974 various tp_print implementations of the built-in types and those in
6975 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006976
Georg Brandl3ee81df2008-05-17 18:14:43 +00006977- Issue #1147: Exceptions were directly allowing string exceptions in
6978 their throw() method even though string exceptions no longer
6979 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006980
Georg Brandl3ee81df2008-05-17 18:14:43 +00006981- Issue #1096: Prevent a segfault from getting the repr of a very
6982 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006983
Brett Cannon1e534b52007-09-07 04:18:30 +00006984- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006985 PyObject_Call() never calling back out to Python code to trigger
6986 recursion depth updates/checks. Required the creation of a static
6987 RuntimeError instance in case normalizing an exception put the
6988 recursion check value past its limit. Fixes crashers
6989 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006990
Georg Brandl3ee81df2008-05-17 18:14:43 +00006991- Patch #1031213: Decode source line in SyntaxErrors back to its

6995 with %G.
6996
Georg Brandl3ee81df2008-05-17 18:14:43 +00006997- Prevent expandtabs() on string and unicode objects from causing a
6998 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006999
Georg Brandl3ee81df2008-05-17 18:14:43 +00007000- Issue #1733488: Fix compilation of bufferobject.c on AIX.
Martin v. Löwisda587ab2007-06-08 17:29:20 +00007001

Neal Norwitz0ac60192007-05-27 04:08:54 +00007004- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007005 __*__ attributes. (Some already existed, e.g., __doc__ and

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007008- Add -3 option to the interpreter to warn about features that are
7009 deprecated and will be changed/removed in Python 3.0.
7010
Georg Brandl2134e752007-05-21 20:34:16 +00007011- Patch #1686487: you can now pass any mapping after '**' in function
7012 calls.
7013
Collin Winter62903052007-05-18 23:11:24 +00007014- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007015 "except E as target:". This is to provide forwards compatibility
7016 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007017
Brett Cannon229cee22007-05-05 01:34:02 +00007018- Deprecate BaseException.message as per PEP 352.
7019
Georg Brandl3ee81df2008-05-17 18:14:43 +00007020- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007021 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007022
Vinay Sajip8549ce32007-05-06 17:53:37 +00007023- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007024 setting a plain string, ie don't expand to single letter identifiers.
7025
Raymond Hettinger13936692007-04-11 18:40:58 +00007026- Request #1191699: Slices can now be pickled.
7027
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007028- Request #1193128: str.translate() now allows a None argument for
7029 translations that only remove characters without re-mapping the
7030 remaining characters.
7031
Georg Brandl5cb76c12007-03-21 09:00:39 +00007032- Patch #1682205: a TypeError while unpacking an iterable is no longer
7033 masked by a generic one with the message "unpack non-sequence".
7034
Neal Norwitzaa754b72007-03-21 06:39:48 +00007035- Remove unused file Python/fmod.c.
7036
Guido van Rossum143b5642007-03-23 04:58:42 +00007037- Bug #1683368: The object.__init__() and object.__new__() methods are
7038 now stricter in rejecting excess arguments. The only time when
7039 either allows excess arguments is when it is not overridden and the
7040 other one is. For backwards compatibility, when both are
7041 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007042 warning later). Also, type.__init__() insists on the same signature
7043 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007044
Georg Brandl3ee81df2008-05-17 18:14:43 +00007045- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7046 object to complex using its __complex__() method before falling back
7047 to the __float__() method. Therefore, the functions in the cmath
7048 module now can operate on objects that define a __complex__()
7049 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007050
Georg Brandl3ee81df2008-05-17 18:14:43 +00007051- Patch #1623563: allow __class__ assignment for classes with
7052 __slots__. The old and the new class are still required to have the
7053 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007054
Georg Brandl3ee81df2008-05-17 18:14:43 +00007055- Patch #1642547: Fix an error/crash when encountering syntax errors
7056 in complex if statements.

7059 ``object.__reduce_ex__()`` is called with an object that is faking
7060 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007061
Georg Brandl3ee81df2008-05-17 18:14:43 +00007062- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00007065- Patch #1444529: the builtin compile() now accepts keyword arguments.
7066
Georg Brandl7b9c5552007-03-12 14:30:05 +00007067- Bug #1678647: write a newline after printing an exception in any
7068 case, even when converting the value to a string failed.
7069
Georg Brandl871f1bc2007-03-12 13:17:36 +00007070- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007071 its argument, if it exists. If not, it will work like before. This
7072 allows customizing the output of dir() in the presence of a
7073 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007074
Collin Winter276887b2007-03-12 16:11:39 +00007075- Patch #922167: Python no longer segfaults when faced with infinitely
7076 self-recursive reload() calls (as reported by bug #742342).
7077
Georg Brandl3ee81df2008-05-17 18:14:43 +00007078- Patch #1675981: remove unreachable code from ``type.__new__()``
7079 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007081- Patch #1491866: change the complex() constructor to allow
7082 parthensized forms. This means complex(repr(x)) now works instead of
7083 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007084
Georg Brandlaa2321b2007-03-07 00:40:28 +00007085- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007086 makes the filenames the warning module prints much more sensible
7087 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007088
Georg Brandl49aafc92007-03-07 00:34:46 +00007089- Variant of patch #697613: don't exit the interpreter on a SystemExit
7090 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007091 variable is given, but break into the interactive interpreter just
7092 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007097- Bug #1674503: close the file opened by execfile() in an error
7098 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00007099
Georg Brandl0fca97a2007-03-05 22:28:08 +00007100- Patch #1674228: when assigning a slice (old-style), check for the
7101 sq_ass_slice instead of the sq_slice slot.
7102
Georg Brandl3ee81df2008-05-17 18:14:43 +00007103- When printing an unraisable error, don't print exceptions. before
7104 the name. This duplicates the behavior whening normally printing
7105 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00007106
Georg Brandl3ee81df2008-05-17 18:14:43 +00007107- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00007113- Bug #1377858: Fix the segfaulting of the interpreter when an object
7114 created a weakref on itself during a __del__ call for new-style
7115 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00007116
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00007117- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
7118 frame's thread state.
7119

Georg Brandl2c1375c2006-10-12 11:27:59 +00007155- Bug #1545497: when given an explicit base, int() did ignore NULs
7156 embedded in the string to convert.
7157
Georg Brandl846f73a2006-10-08 07:11:54 +00007158- Bug #1569998: break inside a try statement (outside a loop) is now
7159 recognized and rejected.
7160

7162
Armin Rigo7ccbca92006-10-04 12:17:45 +00007163- A number of places, including integer negation and absolute value,
7164 were fixed to not rely on undefined behaviour of the C compiler
7165 anymore.

7168 number of arguments, as was the case in Python 2.4.
7169
Georg Brandl5d59c092006-09-30 08:43:30 +00007170- Patch #1567691: super() and new.instancemethod() now don't accept

Neal Norwitzdac090d2006-09-05 03:53:08 +00007205- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00007206 generator expressions (x for x, in ... ) works again. Fixing this
7207 problem required changing the .pyc magic number. This means that
7208 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00007247- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00007638 AttributeError instead of an IOError when the server's response
7639 didn't contain a valid HTTP status line.

7671
Georg Brandl92a6bae2007-03-13 17:43:32 +00007672- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007673 are set for invalid interpolation sequences that would lead to
7674 errors on reading back those values.

Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +00007710- Patch #742598: Add .timeout attribute to SocketServer that calls

7717 returned string up to the first NUL character.

7730 TestCase and TestSuite subclasses (not instances) are no longer
7731 accepted in TestSuite.addTest(). This should cause no
7732 incompatibility since it never made sense with ordinary subclasses
7733 -- the failure just occurred later, with a more cumbersome
7734 exception.

8013 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008014
Georg Brandl3ee81df2008-05-17 18:14:43 +00008015- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8016 with RFC 3207 and forgets any knowledge obtained from the server not
8017 obtained from the TLS negotiation itself. Patch contributed by Bill
8018 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008019
Georg Brandl3ee81df2008-05-17 18:14:43 +00008020- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008021 that the SMTP.starttls() caller no longer needs to call ehlo()
8022 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008023 does not claim to support starttls. Adds the
8024 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8105 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8106 silently miscode subclasses of those types. Now, it raises a
8107 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008108

Georg Brandl3ee81df2008-05-17 18:14:43 +00008123 time so that opening a database previously created with the DB_DUP
8124 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8125 opens. Specifically: dictionary assignment to a DB object will
8126 replace all values for a given key when the database allows
8127 duplicate values. DB users should use DB.put(k, v) when they want
8128 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008129

8135 characters with ASCII value less than 32. Also, it correctly quotes
8136 dots only if they occur on a single line, as opposed to the previous
8137 behavior of quoting dots if they are the second character of any
8138 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008139

Georg Brandl3ee81df2008-05-17 18:14:43 +00008474- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8475 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8476 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008477
8478- Patch #1720595: add T_BOOL to the range of structmember types.

8482
Georg Brandl3ee81df2008-05-17 18:14:43 +00008483- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8484 of w# format code incorrectly truncated the length to an int, even
8485 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8486 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008487
Georg Brandl3ee81df2008-05-17 18:14:43 +00008488- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8489 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008495- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8496 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008497
8498- Patch #1733960: Allow T_LONGLONG to accept ints.

8505
8506- Fix some leftovers from the conversion from int to Py_ssize_t
8507 (relevant to strings and sequences of more than 2**31 items).
8508
8509- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8510 outside of pystate.c and should not be necessary.
8511
Georg Brandl3ee81df2008-05-17 18:14:43 +00008512- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8513 absolute imports. In earlier versions they might have used relative

Georg Brandl3ee81df2008-05-17 18:14:43 +00008516- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8517 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008518
Georg Brandl3ee81df2008-05-17 18:14:43 +00008519- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00008526- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8527 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8528 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8529 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008530
Georg Brandl3ee81df2008-05-17 18:14:43 +00008531- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00008544- Removed the macfs module. It had been deprecated since Python 2.5.
8545 This lead to the deprecation of macostools.touched() as it relied
8546 solely on macfs and was a no-op under OS X.
