25
Antoine Pitrou5b4b2da2011-12-15 14:15:31 +010026- Fix the fix for issue #12149: it was incorrect, although it had the side
27 effect of appearing to resolve the issue. Thanks to Mark Shannon for

45 warnings. Patch by Josh Triplett and Petri Lehtinen.
46
Mark Hammond323b5da2011-10-17 11:05:36 +110047- Issue #7833: Extension modules built using distutils on Windows will no
48 longer include a "manifest" to prevent them failing at import time in some
49 embedded situations.
50
Benjamin Petersona7b09762011-10-15 13:43:21 -040051- Issue #13186: Fix __delitem__ on old-style instances when invoked through

Mark Dickinsondbbed042011-09-19 16:38:08 +010060- Issue #12973: Fix overflow checks that invoked undefined behaviour in
61 int.__pow__. These overflow checks were causing int.__pow__ to produce
62 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010063 compiler optimizing the check away. Also fix similar overflow checks
64 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
65 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +010066

Antoine Pitrou16166452011-07-12 22:04:20 +020076- Issue #12149: Update the method cache after a type's dictionnary gets
77 cleared by the garbage collector. This fixes a segfault when an instance
78 and its type get caught in a reference cycle, and the instance's
79 deallocator calls one of the methods on the type (e.g. when subclassing
80 IOBase). Diagnosis and patch by Davide Rizzo.
81
Florent Xiclunaa1f948b2012-01-24 21:05:10 +010082- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +020089 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
90 raw_input() interrupted by CTRL+c.
91
Łukasz Langa7a153902011-10-18 17:16:00 +020092- Issue #10860: httplib now correctly handles an empty port after port
93 delimiter in URLs.
94
Barry Warsawc5643282011-07-19 17:06:30 -040095- dict_proxy objects now display their contents rather than just the class
96 name.

132
Florent Xiclunac2279652012-02-12 14:49:03 +0100133- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100134 has left two versions of customize_compiler, the original in
135 distutils.sysconfig and another copy in distutils.ccompiler, with some
136 parts of distutils calling one and others using the other.
137 Complete the revert back to only having one in distutils.sysconfig as
138 is the case in 3.x.
139
Ned Deily0d0ea482012-02-10 12:59:06 +0100140- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
141 Distutils-based packages with C extension modules may fail because
142 Apple has removed gcc-4.2, the version used to build python.org
143 64-bit/32-bit Pythons. If the user does not explicitly override
144 the default C compiler by setting the CC environment variable,
145 Distutils will now attempt to compile extension modules with clang
146 if gcc-4.2 is required but not found. Also as a convenience, if
147 the user does explicitly set CC, substitute its value as the default
148 compiler in the Distutils LDSHARED configuration variable for OS X.
149 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
150 SDK, neither of which are available in Xcode 4. This change does not
151 attempt to override settings to support their use with Xcode 4.)

156 relevant, instead send method.
157
Petri Lehtinenc7fd5232011-05-09 12:24:09 +0200158- Issue #10811: Fix recursive usage of cursors. Instead of crashing,

160

215 files, display a message popup and continue rather than crash.
216 (original patch by Roger Serwy)
217
Lars Gustäbel9a388632011-12-06 13:07:09 +0100218- tarfile.py: Correctly detect bzip2 compressed streams with blocksizes

220
Raymond Hettingerf5377022011-12-11 22:31:09 -0800221- Issue #13573: The csv.writer now uses the repr() for floats rather than str().

236 raised when the wrapped raw file is non-blocking and the write would block.

Ned Deily87e82bb2011-06-28 19:52:59 -0700426- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
427 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
428 interpreter process. This could cause failures in non-Distutils subprocesses
429 and was unreliable since tests or user programs could modify the interpreter
430 environment after Distutils set it. Instead, have Distutils set the the
431 deployment target only in the environment of each build subprocess. It is
432 still possible to globally override the default by setting
433 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
434 greater or equal to the default value, the value with which the interpreter
435 was built.

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

Raymond Hettinger20397532010-09-12 02:11:45 +00001411- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1412 This prevents user-created self-referencing ordered dictionaries from
1413 becoming permanently uncollectable GC garbage. The downside is that
1414 removing __del__ means that the internal doubly-linked list has to wait for
1415 GC collection rather than freeing memory immediately when the refcnt drops
1416 to zero.

1425 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001875- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1876 start byte and the continuation byte(s) are now considered invalid, instead
1877 of the number of bytes specified by the start byte.
1878 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1879 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1880 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001889- Issue #8748: Fix two issues with comparisons between complex and integer
1890 objects. (1) The comparison could incorrectly return True in some cases
1891 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1892 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlfee0f442010-05-22 21:26:21 +00002033- Issue #1533: Fix inconsistency in range function argument processing: any
2034 non-float non-integer argument is now converted to an integer (if possible)
2035 using its __int__ method. Previously, only small arguments were treated this
2036 way; larger arguments (those whose __int__ was outside the range of a C long)
2037 would produce a TypeError.

2088 operation raises multiple signals and more than one of those signals is
2089 trapped, the specification determines the order in which the signals should be

Georg Brandlfee0f442010-05-22 21:26:21 +00002266- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002267 on 64-bit machines. The shift count for either left or right shift is
2268 permitted to be up to sys.maxsize.
2269
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002270- Ensure that tokenization of identifiers is not affected by locale.
2271
Georg Brandlfee0f442010-05-22 21:26:21 +00002272- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002274- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2275
Georg Brandlfee0f442010-05-22 21:26:21 +00002276- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2277 with a non-empty format string. This is an effort to future-proof user
2278 code. If a derived class does not currently implement __format__ but later
2279 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002280 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002281 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002282
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002283- Issue #8268: Old-style classes (not just instances) now support weak
2284 references.

Victor Stinner66644262010-03-10 22:30:19 +00002296- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002297 (SIGINT). If an error occurs while importing the site module, the error is
2298 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002299 module.

2313
Georg Brandlfee0f442010-05-22 21:26:21 +00002314- Issue #8257: The Decimal construct now accepts a float instance directly,
2315 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002316
2317 >>> Decimal(1.1)
2318 Decimal('1.100000000000000088817841970012523233890533447265625')
2319
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002320- collections.Counter() now supports a subtract() method.
2321
Georg Brandlfee0f442010-05-22 21:26:21 +00002322- The functools module now has a total_ordering() class decorator to simplify
2323 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002325- The functools module also adds cmp_to_key() as a tool to transition old-style
2326 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002327
Georg Brandlfee0f442010-05-22 21:26:21 +00002328- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2329 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002330
Georg Brandlfee0f442010-05-22 21:26:21 +00002331- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2332 InvalidOperation instead of returning False. (Comparisons involving a quiet
2333 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2334 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002335
Georg Brandlfee0f442010-05-22 21:26:21 +00002336- Issue #2531: Comparison operations between floats and Decimal instances now
2337 return a result based on the numeric values of the operands; previously they
2338 returned an arbitrary result based on the relative ordering of id(float) and
2339 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002340
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002341- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002342 argument `-` which tells it to read files to compile from stdin. Each line is
2343 read on demand and the named file is compiled immediately. (Original patch by
2344 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002345
Georg Brandlfee0f442010-05-22 21:26:21 +00002346- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002349- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2350 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002351 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002352
Georg Brandlfee0f442010-05-22 21:26:21 +00002353- Comparisons using one of <, <=, >, >= between a complex instance and a
2354 Fractions instance now raise TypeError instead of returning True/False. This
2355 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2356 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002357

Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002371- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2372 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00002412 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2413 log file to compute the next rollover time. If the log file does not exist,
2414 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002415

2425 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2426 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002455- Issue #8300: When passing a non-integer argument to struct.pack with any
2456 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002460- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2461 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2462 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002463 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2464 inconsistent: __int__ was used for some integer codes but not for others, and
2465 the set of integer codes for which it was used differed between native packing
2466 and standard packing.)

Mark Dickinson8efef5c2010-01-12 22:23:56 +00002729
Georg Brandlba83f822010-03-14 09:50:54 +00002730 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
2731 strings,
2732 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2733 numeric strings corresponding to subnormal values,
2734 (3) a memory leak for some values large enough to cause overflow, and
2735 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00002774 file position when calling `truncate()`. It would previously change the file
2775 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002776 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2779 class used to represent files stored inside an archive. The new
2780 implementation is significantly faster and can be wrapped in a
2781 ``io.BufferedReader`` object for more speedups. It also solves an issue
2782 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002793- Issue #7748: Since unicode values are supported for some metadata options in
2794 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2795 encoded string for them. This ensures that the upload and register commands
2796 send the correct values to PyPI without any error.

2870Core and Builtins
2871-----------------
2872
Georg Brandlba83f822010-03-14 09:50:54 +00002873- The ``__complex__()`` method is now looked up on the class of instances to
2874 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002876- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2877 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2878
Mark Dickinson1b34d252010-01-01 17:27:30 +00002879- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002880 DeprecationWarning when passed a float argument where an integer was expected.
2881 These functions and methods now raise TypeError instead. The majority of the
2882 effects of this change are in the extension modules, but some core functions
2883 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2884 and many unicode/str methods.

2898 of integers: the result of a/b is now correctly rounded for ints a and b (at
2899 least on IEEE 754 platforms), and in particular does not depend on the
2900 internal representation of a long.

2908
Georg Brandlba83f822010-03-14 09:50:54 +00002909 These executables now work properly with the arch(1) command: ``arch -ppc
2910 python`` will start a universal binary version of python in PPC mode (unlike

3051 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003052

Georg Brandlba83f822010-03-14 09:50:54 +00003067- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3068 decimal string that's guaranteed to round back to x under correct rounding
3069 (with round-half-to-even rounding mode). Previously it gave a string based on
3070 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3071 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3072 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003073
Georg Brandlba83f822010-03-14 09:50:54 +00003074- Issue #7117: On almost all platforms: float-to-string and string-to-float
3075 conversions within Python are now correctly rounded. Places these conversions
3076 occur include: str for floats and complex numbers; the float and complex
3077 constructors; old-style and new-style numeric formatting; serialization and
3078 deserialization of floats and complex numbers using marshal, pickle and json;
3079 parsing of float and imaginary literals in Python code; Decimal-to-float
3080 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003081
Georg Brandlba83f822010-03-14 09:50:54 +00003082 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3083 providing correctly-rounded strtod and dtoa C functions. This code is
3084 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3085 the C compiler. There may be a small number of platforms on which correct
3086 operation of this code cannot be guaranteed, so the code is not used: notably,
3087 this applies to platforms where the C double format is not IEEE 754 binary64,
3088 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3089 and Python's configure script is unable to determine how to change the FPU
3090 precision. On these platforms conversions use the platform strtod and dtoa,
3091 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003092
Georg Brandlba83f822010-03-14 09:50:54 +00003093- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3094 uses the correctly-rounded string <-> float conversions described above (when
3095 available), and so produces correctly rounded results that will display nicely
3096 under the float repr. There are two related small changes: (1) round now
3097 accepts any class with an ``__index__()`` method for its second argument (but
3098 no longer accepts floats for the second argument), and (2) an excessively
3099 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3100 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003242
Georg Brandlba83f822010-03-14 09:50:54 +00003243 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3244 (2) parsing of strings representing infinities and nans was locale aware; and
3245 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003247- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3248 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3249 but with at least one decimal point and with a default precision
3250 of 12. Previously, the behavior the same but with a default precision of 6.
3251 This more closely matches ``str()``, and reduces surprises when adding
3252 alignment flags to the empty presentation type. This also affects the new
3253 complex.__format__ in the same way.
3254
3255- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00003436- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3437 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3438 instances. On a typical machine this saves 3 bytes of memory (on average) per
3439 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003441- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Georg Brandlba83f822010-03-14 09:50:54 +00003445- Issue #3689: The list reversed iterator now supports __length_hint__ instead

3450
Georg Brandlba83f822010-03-14 09:50:54 +00003451- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3452 file objects with closefd=False. The file descriptor is still kept open but
3453 the file object behaves like a closed file. The ``FileIO`` object also got a
3454 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00003477- On windows, ``os.chdir()`` given unicode was not working if

3479 this code path is really executed because I cannot move to such directory on
3480 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003482- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3483 element is temporarily replaced with an equivalent frozenset. But the
3484 eventual KeyError would always report the empty ``frozenset()`` as the missing
3485 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003505- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3506 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3507 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3508 of using the replace error handler in PyUnicode_DecodeUTF8().
3509
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003510- Issue #3739: The unicode-internal encoder now reports the number of characters

3512
Georg Brandlba83f822010-03-14 09:50:54 +00003513- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3514 allocator will be automatically disabled when running under Valgrind. This
3515 gives improved memory leak detection when running under Valgrind, while taking
3516 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004881- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4882
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004883- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4884 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4885 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4886 ``printf`` function, whereas PyString_FromFormat has an independent
4887 implementation and uses "%zd" on all platforms for size_t values.
4888 This makes a difference on win64, where ``printf`` needs "%Id" to display
4889 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004891- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4895 object; previously an int would be returned for small values. the __long__
4896 method is allowed to return either an int or a long, but the behaviour of
4897 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004899- Issue #3751: str.rpartition would perform a left-partition when called with

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004906 was correctly parsed but parsing of subsequent arguments failed.
4907
Vinay Sajip35e3b032008-09-01 14:33:59 +00004908- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004909 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4910 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4911 when given a tuple of classes as second argument, were looking up
4912 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4913 type object.
4914

5058-----------------
5059
Guido van Rossumf8402962008-08-20 15:01:50 +00005060- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5061 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5062 extensions do not automatically benefit from the class attribute
5063 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5064 to their tp_flags field if they care. This is a backwards
5065 compatibility feature; in 3.0, all types will use the cache by
5066 default.
5067
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005068- Keyword arguments can now follow starred arguments. (``f(a, *args,
5069 keyword=23)`` is now valid syntax.)
5070
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005071- ctypes function pointers that are COM methods have a boolean True
5072 value again.

5083
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005084- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5085 (64bit Unix, for example), unichr() would truncate its argument and return
5086 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Neal Norwitze7d8be82008-07-31 17:17:14 +00005088- Apply security patches from Apple.
5089
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005090- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00005093- Issue #1819: function calls with several named parameters are now on
5094 average 35% faster (as measured by pybench).
5095
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005096- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5097 the python debugger steps into a class statement: the free variables (local

Gregory P. Smith0470bab2008-07-22 04:46:32 +00005100- Issue #2620: Overflow checking when allocating or reallocating memory
5101 was not always being done properly in some python types and extension
5102 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5103 all been updated to perform better checks and places in the code that
5104 would previously leak memory on the error path when such an allocation
5105 failed have been fixed.

5113 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5114
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005115- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5116 version reported by these tools does not necessarily follow the python
5117 version numbering scheme, so the module is less strict when parsing it.
5118
Nick Coghlanf70385a2008-08-18 12:42:46 +00005119- Issue #2235: Added Py3k warnings for types which will become unhashable
5120 under the stricter __hash__ inheritance rules in 3.0. Several types
5121 which did not meet the rules for hash invariants and were already
5122 unhashable in 3.0 have now been explicitly flagged as unhashable in
5123 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5124 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5125
Brett Cannon88f801d2008-08-18 00:46:22 +00005126- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5158 since mimetools itself is deprecated. Because modules are cached, all
5159 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5160

5170 a MemoryError rather than silently stop the iteration.
5171
Guido van Rossum59ce9012008-08-09 14:55:34 +00005172- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5173 to _sre.compile() will now be rejected. This should not affect anybody
5174 since the re.compile() function never generates invalid re-bytecode.
5175
Skip Montanaroa032bf42008-08-08 22:52:51 +00005176- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5177 upon first access it can be automatically initialized from the csv file if
5178 it wasn't initialized during instantiation.
5179
Brett Cannon3aa2a492008-08-06 22:28:09 +00005180- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5181 the reload() built-in has been removed.
5182
Brett Cannon7e30b672008-08-04 21:52:25 +00005183- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005184 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005195 asking for a specific length. This problem only affected files opened
5196 using the new "io" module, not the built-in open() function.

5222 file name rather than a ZipInfo instance, so files are extracted with
5223 mode 0600 rather than 000 under Unix.
5224
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005225- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5226 argument in python 2.5, this broke code that subclassed Popen to include its

5238 interaction with the tp_hash slot (added in 2.6b2) are now documented
5239
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005240- Issue #643841: The language reference now provides more detailed
5241 coverage of the lookup process for special methods. The disclaimers
5242 regarding lack of coverage of new-style classes have also been
5243 removed, since the coverage is now fairly reasonable.

5247================================
5248
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005249*Release date: 17-Jul-2008*
5250
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005251Core and Builtins
5252-----------------
5253
Georg Brandl3e483f62008-07-16 22:57:41 +00005254- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5255 its methods now allow for items objects that can be converted to
5256 an integer using operator.index().
5257
Mark Dickinson64b7e502008-07-16 09:40:03 +00005258- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5259 produced a ValueError instead of giving the correct float.
5260
Eric Smitha5fa5a22008-07-16 00:11:49 +00005261- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5262 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5263
Mark Dickinson7103aa42008-07-15 19:08:33 +00005264- Issue #3008: the float type has a new instance method 'float.hex'
5265 and a new class method 'float.fromhex' to convert floating-point
5266 numbers to and from hexadecimal strings, respectively.
5267
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005268- Issue #2235: __hash__ is once again inherited by default. To allow
5269 collections.Hashable to remain meaningful in the presence of the
5270 default hash implementation (object.__hash__), it is now possible
5271 to explicit block inheritance of hash by setting __hash__=None at
5272 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5273 level.
5274
Nick Coghlanb028f502008-07-13 14:52:36 +00005275- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5276 the parent module cannot be found while performing an absolute import.
5277 This means that an incorrectly defined __package__ attribute will
5278 now only prevent relative imports in that module rather than causing
5279 all imports from that module to fail.
5280
Nick Coghlan14ff9942008-07-08 14:21:42 +00005281- Issue #2517: Allow unicode messages in Exceptions again by correctly
5282 bypassing the instance dictionary when looking up __unicode__ on
5283 new-style classes.
5284
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005285- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5286 set to a custom object whose write() method happens to install
5287 another file in sys.stdout.
5288
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005289- Issue #3088: Corrected a race condition in classes derived from
5290 threading.local: the first member set by a thread could be saved in
5291 another thread's dictionary.
5292
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005293- Issue #3004: Minor change to slice.indices(): the start and stop
5294 arguments are now treated identically, making the behaviour easier
5295 to describe and understand. For example, slice(None, -10,
5296 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5297 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5298 10, -1).
5299
Georg Brandl278fc502008-07-19 12:46:12 +00005300- Issue #3219: Calling a function with repeated keyword arguments,
5301 f(a=2, a=23), would not cause a syntax error. This was a regression
5302 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005303
Georg Brandl278fc502008-07-19 12:46:12 +00005304- Issue #2862: Make int and float freelist management consistent with
5305 other freelists. Changes their CompactFreeList apis into
5306 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00005311- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5312 api functions without holding the GIL, which could lead to a fatal
5313 error when they failed.
5314
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005315- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005323- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5324 ForkingPickler.register() to resolve conflict with ctypes.
5325
Vinay Sajip51e65192008-07-18 09:01:10 +00005326- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005327
Thomas Heller880f5292008-07-15 19:39:38 +00005328- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5329 a valid dlerror() message.
5330
Thomas Heller2bad6572008-07-15 17:19:50 +00005331- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5332 incomplete structure was created.
5333

5337
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005338- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005339
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005340- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5341 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005342 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005343 content-length. The problem had been corrected in the 2.4 branch, but never
5344 merged into trunk.
5345
Georg Brandle78fbcc2008-07-05 10:13:36 +00005346- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005357 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005358
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005359- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5360 handling is now the same as that of other special attributes like __name__).
5361
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005362- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5363 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00005752 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005753
5754 This is controlled by the configure argument ``--with-universal-archs``:
5755
5756 - ``--with-universal-archs=all``: install 4-way universal
5757
5758 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5759
5760 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5761
5762 This option should be used in combination with ``--enable-universalsdk=``.
5763
5764 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 +00005814- Issue #1631171: Re-implement the 'warnings' module in C (the
5815 original Python code has been kept as backup). This will allow for
5816 using the 'warning's machinery in such places as the parser where
5817 use of pure Python code is not possible. Both the ``showarning()``
5818 and ``formatwarning()`` gain an optional 'line' argument which is
5819 not called by default for backwards-compatibility reasons. Setting
5820 ``warnings.showwarning()`` to an implementation that lacks support
5821 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005884- Issue #2550: The approach used by client/server code for obtaining
5885 ports to listen on in network-oriented tests has been refined in an
5886 effort to facilitate running multiple instances of the entire
5887 regression test suite in parallel without issue.
5888 test_support.bind_port() has been fixed such that it will always
5889 return a unique port -- which wasn't always the case with the
5890 previous implementation, especially if socket options had been set
5891 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5892 new implementation of bind_port() will actually raise an exception
5893 if it is passed an AF_INET/SOCK_STREAM socket with either the
5894 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5895 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5896 the socket it's been passed. This currently only applies to
5897 Windows. This option prevents any other sockets from binding to the
5898 host/port we've bound to, thus removing the possibility of the
5899 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5900 when a second SOCK_STREAM socket binds and accepts to a host/port
5901 that's already been bound by another socket. The optional preferred
5902 port parameter to bind_port() has been removed. Under no
5903 circumstances should tests be hard coding ports!
5904
5905 test_support.find_unused_port() has also been introduced, which will
5906 pass a temporary socket object to bind_port() in order to obtain an
5907 unused port. The temporary socket object is then closed and
5908 deleted, and the port is returned. This method should only be used
5909 for obtaining an unused port in order to pass to an external program
5910 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5911 a parameter to a server-oriented class that doesn't give you direct
5912 access to the underlying socket used.
5913
5914 Finally, test_support.HOST has been introduced, which should be used
5915 for the host argument of any relevant socket calls (i.e. bind and
5916 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005917
5918 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005919 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005920 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5921 test_asynchat and test_socket_ssl.
5922
Georg Brandl3ee81df2008-05-17 18:14:43 +00005923 It is now possible for multiple instances of the regression test

Fred Drakea8ee94b2008-03-01 02:45:07 +00006193- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006194 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006195
Georg Brandlad61bc82008-02-23 15:11:18 +00006196- Issue #2067: file.__exit__() now calls subclasses' close() method.
6197
6198- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006199
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006200- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006201 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006202
Eric Smitha73fbe72008-02-23 03:09:44 +00006203- Added the future_builtins module, which contains hex() and oct().
6204 These are the PEP 3127 version of these functions, designed to be
6205 compatible with the hex() and oct() builtins from Python 3.0. They
6206 differ slightly in their output formats from the existing, unchanged
6207 Python 2.6 builtins. The expected usage of the future_builtins
6208 module is:
6209 from future_builtins import hex, oct
6210
Eric Smith7ef40bf2008-02-20 23:34:22 +00006211- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6212 exponents for exponents with absolute value < 100. Follows C99
6213 standard. This is a change on Windows, which would use 3 digits.
6214 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6215 so that any alterations it does to the resulting string will be
6216 available in stringlib/formatter.h (for float.__format__).
6217
Eric Smith5a3c1352008-02-19 13:21:56 +00006218- Implemented PEP 3101, Advanced String Formatting. This adds a new
6219 builtin format(); a format() method for str and unicode; a
6220 __format__() method to object, str, unicode, int, long, float, and
6221 datetime; the class string.Formatter; and the C API
6222 PyObject_Format().
6223
Georg Brandl3ee81df2008-05-17 18:14:43 +00006224- Fixed several potential crashes, all caused by specially crafted
6225 __del__ methods exploiting objects in temporarily inconsistent
6226 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006227
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006228- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006229 prevent a possible crash: an Abstract Base Class would try to access
6230 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006231
Georg Brandl3ee81df2008-05-17 18:14:43 +00006232- Fixed repr() and str() of complex numbers with infinity or nan as
6233 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006234
Georg Brandl3ee81df2008-05-17 18:14:43 +00006235- Clear all free lists during a gc.collect() of the highest generation
6236 in order to allow pymalloc to free more arenas. Python may give back
6237 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006238
Georg Brandl3ee81df2008-05-17 18:14:43 +00006239- Issue #2045: Fix an infinite recursion triggered when printing a
6240 subclass of collections.defaultdict, if its default_factory is set
6241 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006242
Christian Heimesf75dbef2008-02-08 00:11:31 +00006243- Fixed a minor memory leak in dictobject.c. The content of the free
6244 list was not freed on interpreter shutdown.
6245
Georg Brandl21e99f42010-03-07 15:23:59 +00006246- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006247 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006248
Georg Brandl3ee81df2008-05-17 18:14:43 +00006249- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6250 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006251 to compact the internal free lists of pre-allocted ints and floats.
6252
Georg Brandl3ee81df2008-05-17 18:14:43 +00006253- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6254 calls. Python expected the return type int but the fork familie
6255 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006257- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6258 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006259
Georg Brandl3ee81df2008-05-17 18:14:43 +00006260- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6261 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006262
Georg Brandl3ee81df2008-05-17 18:14:43 +00006263- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6264 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006265
Georg Brandl3ee81df2008-05-17 18:14:43 +00006266- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6267 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006268
Georg Brandl3ee81df2008-05-17 18:14:43 +00006269- Patch #1473257: generator objects gain a gi_code attribute. This is
6270 the same object as the func_code attribute of the function that
6271 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006272
Georg Brandl3ee81df2008-05-17 18:14:43 +00006273- Issue #1920: "while 0" statements were completely removed by the
6274 compiler, even in the presence of an "else" clause, which is
6275 supposed to be run when the condition is false. Now the compiler
6276 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006277
Guido van Rossumeead05f2008-01-24 18:21:02 +00006278- A few crashers fixed: weakref_in_del.py (issue #1377858);
6279 loosing_dict_ref.py (issue #1303614, test67.py);
6280 borrowed_ref_[34].py (not in tracker).
6281
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006282- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006283 suppressed while an extension is loaded by calling SetErrorMode in
6284 dynload_win.c. The error is still reported properly.
6285
Georg Brandl3ee81df2008-05-17 18:14:43 +00006286- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006287 several extension methods and modules do not work without unicode
6288 support.
6289
Georg Brandl26543b12008-01-21 18:36:51 +00006290- Issue #1882: when compiling code from a string, encoding cookies in the
6291 second line of code were not always recognized correctly.
6292
Georg Brandl14404b62008-01-19 19:27:05 +00006293- Issue #1679: "0x" was taken as a valid integer literal.
6294
Georg Brandl6caad7d2008-01-26 14:19:22 +00006295- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006296 added.
6297
Christian Heimesc94e2b52008-01-14 04:13:37 +00006298- sys.float_info / PyFloat_GetInfo: The floating point information
6299 object was converted from a dict to a specialized structseq object.
6300
Georg Brandl3ee81df2008-05-17 18:14:43 +00006301- Patch #1816: Added sys.flags structseq. It exposes the status of
6302 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006303
Georg Brandl3ee81df2008-05-17 18:14:43 +00006304- Objects/structseq.c: Implemented new structseq representation. The
6305 patch makes structseqs (e.g. the return value of os.stat) more
6306 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006307
Georg Brandl3ee81df2008-05-17 18:14:43 +00006308- Patch #1700288: added a type attribute cache that caches method
6309 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006310
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006311- Bug #1776: __import__() no longer accepts filenames on any platform.
6312 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006313
Georg Brandlaed6c662008-01-07 17:25:53 +00006314- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6315
Georg Brandl3ee81df2008-05-17 18:14:43 +00006316- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6317 envvar and sys.dont_write_bytecode attribute. All these can be set
6318 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006319
Georg Brandl3ee81df2008-05-17 18:14:43 +00006320- Improve some exception messages when Windows fails to load an
6321 extension module. Now we get for example '%1 is not a valid Win32
6322 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006323
Georg Brandl3ee81df2008-05-17 18:14:43 +00006324- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006326- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6327 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006328
Christian Heimes0a8143f2007-12-18 23:22:54 +00006329- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006330 and INF. float("nan"), float("inf") and float("-inf") now work on
6331 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006332
Georg Brandl3ee81df2008-05-17 18:14:43 +00006333- Compiler now generates simpler and faster code for dictionary
6334 literals. The oparg for BUILD_MAP now indicates an estimated
6335 dictionary size. There is a new opcode, STORE_MAP, for adding
6336 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006337
Georg Brandl3ee81df2008-05-17 18:14:43 +00006338- Issue #1638: %zd configure test fails on Linux.

6366 file can now be directly executed by passing their name to the
6367 interpreter. The directory/zipfile is automatically inserted as the
6368 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006369
Georg Brandl3ee81df2008-05-17 18:14:43 +00006370- Issue #1265: Fix a problem with sys.settrace, if the tracing
6371 function uses a generator expression when at the same time the
6372 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006373
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006374- sets and frozensets now have an isdisjoint() method.
6375
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006376- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00006378- Fix warnings found by the new version of the Coverity checker.
6379
Georg Brandl21e99f42010-03-07 15:23:59 +00006380- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006381 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6382 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006383
Georg Brandl3ee81df2008-05-17 18:14:43 +00006384- Issue #1686386: Tuple's tp_repr did not take into account the
6385 possibility of having a self-referential tuple, which is possible
6386 from C code. Nor did object's tp_str consider that a type's tp_str
6387 could do something that could lead to an inifinite recursion.
6388 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6389 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006390
Georg Brandl3ee81df2008-05-17 18:14:43 +00006391- Issue #1164: It was possible to trigger deadlock when using the
6392 'print' statement to write to a file since the GIL was not released
6393 as needed. Now PyObject_Print() does the right thing along with
6394 various tp_print implementations of the built-in types and those in
6395 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006396
Georg Brandl3ee81df2008-05-17 18:14:43 +00006397- Issue #1147: Exceptions were directly allowing string exceptions in
6398 their throw() method even though string exceptions no longer
6399 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006400

6402 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006403
Brett Cannon1e534b52007-09-07 04:18:30 +00006404- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006405 PyObject_Call() never calling back out to Python code to trigger
6406 recursion depth updates/checks. Required the creation of a static
6407 RuntimeError instance in case normalizing an exception put the
6408 recursion check value past its limit. Fixes crashers
6409 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006410

Neal Norwitz0ac60192007-05-27 04:08:54 +00006424- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006425 __*__ attributes. (Some already existed, e.g., __doc__ and
6426 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006427
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006428- Add -3 option to the interpreter to warn about features that are
6429 deprecated and will be changed/removed in Python 3.0.
6430
Georg Brandl2134e752007-05-21 20:34:16 +00006431- Patch #1686487: you can now pass any mapping after '**' in function
6432 calls.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006435 "except E as target:". This is to provide forwards compatibility
6436 with Python 3.0.

Guido van Rossum143b5642007-03-23 04:58:42 +00006457- Bug #1683368: The object.__init__() and object.__new__() methods are
6458 now stricter in rejecting excess arguments. The only time when
6459 either allows excess arguments is when it is not overridden and the
6460 other one is. For backwards compatibility, when both are
6461 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006462 warning later). Also, type.__init__() insists on the same signature
6463 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006465- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6466 object to complex using its __complex__() method before falling back
6467 to the __float__() method. Therefore, the functions in the cmath
6468 module now can operate on objects that define a __complex__()
6469 method.

6489
Georg Brandl871f1bc2007-03-12 13:17:36 +00006490- The dir() function has been extended to call the __dir__() method on

6492 allows customizing the output of dir() in the presence of a

Georg Brandlaa2321b2007-03-07 00:40:28 +00006505- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006506 makes the filenames the warning module prints much more sensible
6507 when a PYTHONSTARTUP file is used.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007435- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7436 with RFC 3207 and forgets any knowledge obtained from the server not
7437 obtained from the TLS negotiation itself. Patch contributed by Bill
7438 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007439
Georg Brandl3ee81df2008-05-17 18:14:43 +00007440- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007441 that the SMTP.starttls() caller no longer needs to call ehlo()
7442 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007443 does not claim to support starttls. Adds the
7444 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7525 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7526 silently miscode subclasses of those types. Now, it raises a
7527 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007528

Georg Brandl3ee81df2008-05-17 18:14:43 +00007543 time so that opening a database previously created with the DB_DUP
7544 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7545 opens. Specifically: dictionary assignment to a DB object will
7546 replace all values for a given key when the database allows
7547 duplicate values. DB users should use DB.put(k, v) when they want
7548 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007549

7555 characters with ASCII value less than 32. Also, it correctly quotes
7556 dots only if they occur on a single line, as opposed to the previous
7557 behavior of quoting dots if they are the second character of any
7558 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007559

Georg Brandl3ee81df2008-05-17 18:14:43 +00007903- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7904 of w# format code incorrectly truncated the length to an int, even
7905 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7906 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007908- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7909 Py_TYPE and Py_REFCNT.

7926- Fix some leftovers from the conversion from int to Py_ssize_t
7927 (relevant to strings and sequences of more than 2**31 items).
7928
7929- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7930 outside of pystate.c and should not be necessary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007936- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7937 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007938
Georg Brandl3ee81df2008-05-17 18:14:43 +00007939- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00007946- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7947 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7948 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7949 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007964- Removed the macfs module. It had been deprecated since Python 2.5.
7965 This lead to the deprecation of macostools.touched() as it relied
7966 solely on macfs and was a no-op under OS X.
