Mark Dickinsondbbed042011-09-19 16:38:08 +010038- Issue #12973: Fix overflow checks that invoked undefined behaviour in
39 int.__pow__. These overflow checks were causing int.__pow__ to produce
40 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010041 compiler optimizing the check away. Also fix similar overflow checks
42 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
43 bugs caused test failures with recent versions of Clang.

55 cleared by the garbage collector. This fixes a segfault when an instance
56 and its type get caught in a reference cycle, and the instance's
57 deallocator calls one of the methods on the type (e.g. when subclassing
58 IOBase). Diagnosis and patch by Davide Rizzo.
59

Éric Araujob21f51a2011-10-23 04:37:51 +0200108 does, instead of converting it to a raw buffer. This also fixes handling of

246
Ned Deily87e82bb2011-06-28 19:52:59 -0700247- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
248 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
249 interpreter process. This could cause failures in non-Distutils subprocesses
250 and was unreliable since tests or user programs could modify the interpreter
251 environment after Distutils set it. Instead, have Distutils set the the
252 deployment target only in the environment of each build subprocess. It is
253 still possible to globally override the default by setting
254 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
255 greater or equal to the default value, the value with which the interpreter
256 was built.

266
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200267- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP

283
Barry Warsawc5643282011-07-19 17:06:30 -0400284- sys.setcheckinterval() now updates the current ticker count as well as
285 updating the check interval, so if the user decreases the check interval,
286 the ticker doesn't have to wind down to zero from the old starting point
287 before the new interval takes effect. And if the user increases the
288 interval, it makes sure the new limit takes effect right away rather have an
289 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700290
Victor Stinner776e69b2011-06-01 01:03:00 +0200291- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

Raymond Hettinger20397532010-09-12 02:11:45 +00001188- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1189 This prevents user-created self-referencing ordered dictionaries from
1190 becoming permanently uncollectable GC garbage. The downside is that
1191 removing __del__ means that the internal doubly-linked list has to wait for
1192 GC collection rather than freeing memory immediately when the refcnt drops
1193 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001652- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1653 start byte and the continuation byte(s) are now considered invalid, instead
1654 of the number of bytes specified by the start byte.
1655 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1656 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

1667 objects. (1) The comparison could incorrectly return True in some cases
1668 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1669 (2) The comparison raised an OverflowError for large integers, leading

1811 non-float non-integer argument is now converted to an integer (if possible)

1865 operation raises multiple signals and more than one of those signals is
1866 trapped, the specification determines the order in which the signals should be
1867 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00002012- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002013 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2014 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2015 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2035Core and Builtins
2036-----------------
2037
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002038- Issue #7301: Add environment variable $PYTHONWARNINGS.
2039
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002040- Issue #8329: Don't return the same lists from select.select when no fds are
2041 changed.
2042
Georg Brandlfee0f442010-05-22 21:26:21 +00002043- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002044 on 64-bit machines. The shift count for either left or right shift is
2045 permitted to be up to sys.maxsize.
2046
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002047- Ensure that tokenization of identifiers is not affected by locale.
2048
Georg Brandlfee0f442010-05-22 21:26:21 +00002049- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002050
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002051- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2052
Georg Brandlfee0f442010-05-22 21:26:21 +00002053- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2054 with a non-empty format string. This is an effort to future-proof user
2055 code. If a derived class does not currently implement __format__ but later
2056 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002057 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002058 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002059
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002060- Issue #8268: Old-style classes (not just instances) now support weak

Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002071- Issue #8164: Don't allow lambda functions to have a docstring.
2072
Victor Stinner66644262010-03-10 22:30:19 +00002073- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002074 (SIGINT). If an error occurs while importing the site module, the error is
2075 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002076 module.

2090
Georg Brandlfee0f442010-05-22 21:26:21 +00002091- Issue #8257: The Decimal construct now accepts a float instance directly,
2092 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002093
2094 >>> Decimal(1.1)
2095 Decimal('1.100000000000000088817841970012523233890533447265625')
2096
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002097- collections.Counter() now supports a subtract() method.
2098
Georg Brandlfee0f442010-05-22 21:26:21 +00002099- The functools module now has a total_ordering() class decorator to simplify
2100 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002101
Georg Brandlfee0f442010-05-22 21:26:21 +00002102- The functools module also adds cmp_to_key() as a tool to transition old-style
2103 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002104
Georg Brandlfee0f442010-05-22 21:26:21 +00002105- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2106 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002107
Georg Brandlfee0f442010-05-22 21:26:21 +00002108- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2109 InvalidOperation instead of returning False. (Comparisons involving a quiet
2110 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2111 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002112
Georg Brandlfee0f442010-05-22 21:26:21 +00002113- Issue #2531: Comparison operations between floats and Decimal instances now
2114 return a result based on the numeric values of the operands; previously they
2115 returned an arbitrary result based on the relative ordering of id(float) and
2116 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002117
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002118- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002119 argument `-` which tells it to read files to compile from stdin. Each line is
2120 read on demand and the named file is compiled immediately. (Original patch by
2121 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002122
Georg Brandlfee0f442010-05-22 21:26:21 +00002123- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002126- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2127 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002128 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002129
Georg Brandlfee0f442010-05-22 21:26:21 +00002130- Comparisons using one of <, <=, >, >= between a complex instance and a
2131 Fractions instance now raise TypeError instead of returning True/False. This
2132 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2133 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002134

2143
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002144- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002145 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2146 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002147
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002148- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

2242 the set of integer codes for which it was used differed between native packing
2243 and standard packing.)

Antoine Pitroubb445a12010-02-05 17:05:54 +00002474- Issue #5677: Explicitly forbid write operations on read-only file objects,
2475 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002476 library would return a bogus result; on Solaris, it was possible to crash the
2477 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00002490- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2491 and add the additional members returned in an OSVERSIONINFOEX structure. The
2492 new members are service_pack_major, service_pack_minor, suite_mask, and
2493 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00002495- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2496 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2497 returning NULL. The macro now returns a statically allocated empty string
2498 instead.

2508 strings,
2509 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2510 numeric strings corresponding to subnormal values,
2511 (3) a memory leak for some values large enough to cause overflow, and
2512 (4) a number of flaws that could lead to incorrectly rounded results.
2513
2514- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
2515 option is not used.

2530 interpreter shutdown.
2531
Georg Brandlba83f822010-03-14 09:50:54 +00002532- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
2533 XML processing instructions and comments. These raw characters are allowed
2534 by the XML specification, and are necessary when outputting e.g. PHP code in
2535 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00002543- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002544 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002545 Also, raise ValueError rather than TypeError when an unknown TIPC address
2546 type is specified. Patch by Brian Curtin.

Vinay Sajip28c382f2010-02-04 18:48:53 +00002548- logging: Implemented PEP 391.
2549
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002550- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002551 file position when calling `truncate()`. It would previously change the file
2552 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002553 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2554
Georg Brandlba83f822010-03-14 09:50:54 +00002555- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2556 class used to represent files stored inside an archive. The new
2557 implementation is significantly faster and can be wrapped in a
2558 ``io.BufferedReader`` object for more speedups. It also solves an issue
2559 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2560 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00002561
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00002562- Issue #7792: Registering non-classes to ABCs raised an obscure error.

2568 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +00002569
Georg Brandlba83f822010-03-14 09:50:54 +00002570- Issue #7748: Since unicode values are supported for some metadata options in
2571 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2572 encoded string for them. This ensures that the upload and register commands
2573 send the correct values to PyPI without any error.

2648-----------------
2649
Georg Brandlba83f822010-03-14 09:50:54 +00002650- The ``__complex__()`` method is now looked up on the class of instances to
2651 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002653- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2654 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2655
Mark Dickinson1b34d252010-01-01 17:27:30 +00002656- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002657 DeprecationWarning when passed a float argument where an integer was expected.
2658 These functions and methods now raise TypeError instead. The majority of the
2659 effects of this change are in the extension modules, but some core functions
2660 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2661 and many unicode/str methods.

2685
Georg Brandlba83f822010-03-14 09:50:54 +00002686 These executables now work properly with the arch(1) command: ``arch -ppc
2687 python`` will start a universal binary version of python in PPC mode (unlike
2688 previous releases).

2828 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002829
Georg Brandlba83f822010-03-14 09:50:54 +00002830- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2831 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002832

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002843
Georg Brandlba83f822010-03-14 09:50:54 +00002844- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2845 decimal string that's guaranteed to round back to x under correct rounding
2846 (with round-half-to-even rounding mode). Previously it gave a string based on
2847 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2848 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2849 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002850
Georg Brandlba83f822010-03-14 09:50:54 +00002851- Issue #7117: On almost all platforms: float-to-string and string-to-float
2852 conversions within Python are now correctly rounded. Places these conversions
2853 occur include: str for floats and complex numbers; the float and complex
2854 constructors; old-style and new-style numeric formatting; serialization and
2855 deserialization of floats and complex numbers using marshal, pickle and json;
2856 parsing of float and imaginary literals in Python code; Decimal-to-float
2857 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002858
Georg Brandlba83f822010-03-14 09:50:54 +00002859 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2860 providing correctly-rounded strtod and dtoa C functions. This code is
2861 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2862 the C compiler. There may be a small number of platforms on which correct
2863 operation of this code cannot be guaranteed, so the code is not used: notably,
2864 this applies to platforms where the C double format is not IEEE 754 binary64,
2865 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2866 and Python's configure script is unable to determine how to change the FPU
2867 precision. On these platforms conversions use the platform strtod and dtoa,
2868 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002869
Georg Brandlba83f822010-03-14 09:50:54 +00002870- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2871 uses the correctly-rounded string <-> float conversions described above (when
2872 available), and so produces correctly rounded results that will display nicely
2873 under the float repr. There are two related small changes: (1) round now
2874 accepts any class with an ``__index__()`` method for its second argument (but
2875 no longer accepts floats for the second argument), and (2) an excessively
2876 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2877 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003024- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3025 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3026 but with at least one decimal point and with a default precision
3027 of 12. Previously, the behavior the same but with a default precision of 6.
3028 This more closely matches ``str()``, and reduces surprises when adding
3029 alignment flags to the empty presentation type. This also affects the new
3030 complex.__format__ in the same way.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00003178- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
3179 file with `str' filename on Windows.
3180
Antoine Pitrouaa687902009-01-01 14:11:22 +00003181- Issue #3680: Reference cycles created through a dict, set or deque iterator
3182 did not get collected.
3183
Georg Brandlba83f822010-03-14 09:50:54 +00003184- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
3185 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00003186
Benjamin Peterson7af65562008-12-29 17:56:58 +00003187- Issue #4764: With io.open, IOError.filename is set when trying to open a
3188 directory on POSIX systems.
3189
Benjamin Petersonfe231b02008-12-29 17:47:42 +00003190- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
3191 systems.
3192
Georg Brandl6425a2f2008-12-28 11:54:53 +00003193- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003194 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003195
Skip Montanarof205c132008-12-23 03:30:15 +00003196- Added test case to ensure attempts to read from a file opened for writing
3197 fail.
3198
Georg Brandlba83f822010-03-14 09:50:54 +00003199- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
3200 elapsed times, not only when some objects are uncollectable/unreachable.
3201 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00003202

Georg Brandlba83f822010-03-14 09:50:54 +00003213- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3214 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3215 instances. On a typical machine this saves 3 bytes of memory (on average) per
3216 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003217
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003218- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3219 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3220 instead of throwing a MemoryError.
3221
Georg Brandlba83f822010-03-14 09:50:54 +00003222- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3223 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003224
Benjamin Petersonc078f922008-11-21 22:27:24 +00003225- Issue #4367: Python would segfault during compiling when the unicodedata
3226 module couldn't be imported and \N escapes were present.
3227
Georg Brandlba83f822010-03-14 09:50:54 +00003228- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3229 file objects with closefd=False. The file descriptor is still kept open but
3230 the file object behaves like a closed file. The ``FileIO`` object also got a
3231 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003232
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003233- Issue #4348: Some bytearray methods returned that didn't cause any change to
3234 the bytearray, returned the same bytearray instead of a copy.
3235
Georg Brandlba83f822010-03-14 09:50:54 +00003236- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00003238- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3239
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003240- Issue #4048: The parser module now correctly validates relative imports.
3241
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003242- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3243 exec statement.
3244
Georg Brandlba83f822010-03-14 09:50:54 +00003245- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3246 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003247
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003248- Issue #4209: Enabling unicode_literals and the print_function in the same
3249 __future__ import didn't work.
3250
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003251- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003252 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003253
Georg Brandlba83f822010-03-14 09:50:54 +00003254- On windows, ``os.chdir()`` given unicode was not working if
3255 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3256 this code path is really executed because I cannot move to such directory on
3257 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003258
Georg Brandlba83f822010-03-14 09:50:54 +00003259- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3260 element is temporarily replaced with an equivalent frozenset. But the
3261 eventual KeyError would always report the empty ``frozenset()`` as the missing
3262 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003263
Georg Brandlba83f822010-03-14 09:50:54 +00003264- Issue #4509: Various issues surrounding resize of bytearray objects to which
3265 there are buffer exports.

3272
Georg Brandlba83f822010-03-14 09:50:54 +00003273- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3274 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003275
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003276- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3277 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003278
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003279- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3280 returned them on 64bit platforms.
3281
Walter Dörwalded960ac2009-05-03 22:36:33 +00003282- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3283 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3284 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3285 of using the replace error handler in PyUnicode_DecodeUTF8().
3286
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003287- Issue #3739: The unicode-internal encoder now reports the number of characters
3288 consumed like any other encoder (instead of the number of bytes).
3289
Georg Brandlba83f822010-03-14 09:50:54 +00003290- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3291 allocator will be automatically disabled when running under Valgrind. This
3292 gives improved memory leak detection when running under Valgrind, while taking
3293 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00003318- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group

Georg Brandlba83f822010-03-14 09:50:54 +00004537 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4538 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00004540- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
4541 regression tests in parallel, shortening the total runtime.
4542
Georg Brandlba83f822010-03-14 09:50:54 +00004543- Issue #5354: New test support function import_fresh_module() makes it easy to
4544 import both normal and optimised versions of modules. test_heapq and
4545 test_warnings have been adjusted to use it, tests for other modules with both
4546 C and Python implementations in the stdlib can be adjusted to use it over
4547 time.

4556 should cause a test to be skipped are now done using import_module from test
4557 support, which does the conversion.

4659
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004660- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4661 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4662 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4663 ``printf`` function, whereas PyString_FromFormat has an independent
4664 implementation and uses "%zd" on all platforms for size_t values.
4665 This makes a difference on win64, where ``printf`` needs "%Id" to display
4666 64bit values.

4672 object; previously an int would be returned for small values. the __long__
4673 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004683 was correctly parsed but parsing of subsequent arguments failed.
4684
Vinay Sajip35e3b032008-09-01 14:33:59 +00004685- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004686 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4687 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4688 when given a tuple of classes as second argument, were looking up
4689 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4690 type object.
4691

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004829What's New in Python 2.6 beta 3?
4830================================
4831
Barry Warsaw07a4a382008-08-21 01:15:08 +00004832*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004833
4834Core and Builtins
4835-----------------
4836
Guido van Rossumf8402962008-08-20 15:01:50 +00004837- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4838 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4839 extensions do not automatically benefit from the class attribute
4840 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4841 to their tp_flags field if they care. This is a backwards
4842 compatibility feature; in 3.0, all types will use the cache by
4843 default.
4844
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004845- Keyword arguments can now follow starred arguments. (``f(a, *args,
4846 keyword=23)`` is now valid syntax.)
4847
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004848- ctypes function pointers that are COM methods have a boolean True
4849 value again.
4850
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004851- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4852 by denying s# to parse objects that have a releasebuffer procedure,
4853 and introducing s*.
4854
Georg Brandl1e13ea92008-08-11 09:07:59 +00004855- Issue #3537: Fix an assertion failure when an empty but presized dict
4856 object was stored in the freelist.
4857
Mark Dickinsonb6467572008-08-04 21:30:09 +00004858- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4859 ValueError consistently across platforms.
4860
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004861- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4862 (64bit Unix, for example), unichr() would truncate its argument and return
4863 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4864
Neal Norwitze7d8be82008-07-31 17:17:14 +00004865- Apply security patches from Apple.
4866
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004867- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4868 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4869
Antoine Pitrou92f82162008-07-25 22:22:08 +00004870- Issue #1819: function calls with several named parameters are now on
4871 average 35% faster (as measured by pybench).
4872
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004873- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4874 the python debugger steps into a class statement: the free variables (local
4875 variables defined in an outer scope) would be deleted from the outer scope.
4876
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004877- Issue #2620: Overflow checking when allocating or reallocating memory
4878 was not always being done properly in some python types and extension
4879 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4880 all been updated to perform better checks and places in the code that
4881 would previously leak memory on the error path when such an allocation
4882 failed have been fixed.
4883
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004884Library
4885-------
4886
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004887- Issue #3612: Added some missing basic types in ctypes.wintypes.
4888
Benjamin Petersone977ad42008-08-20 01:42:01 +00004889- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4890 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4891
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004892- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4893 version reported by these tools does not necessarily follow the python
4894 version numbering scheme, so the module is less strict when parsing it.
4895
Nick Coghlanf70385a2008-08-18 12:42:46 +00004896- Issue #2235: Added Py3k warnings for types which will become unhashable
4897 under the stricter __hash__ inheritance rules in 3.0. Several types
4898 which did not meet the rules for hash invariants and were already
4899 unhashable in 3.0 have now been explicitly flagged as unhashable in
4900 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4901 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4902
Brett Cannon88f801d2008-08-18 00:46:22 +00004903- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4904 imported into the module but exposed as part of the module's API.
4905
Brett Cannon7b96f072008-08-18 00:41:11 +00004906- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4907
Brett Cannon46225e72008-08-18 00:36:52 +00004908- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4909
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004910- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4911
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004912- Issue #3575: Incremental decoder's decode function now takes bytearray
4913 by using 's*' instead of 't#'.
4914
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004915- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004916 fails unicode conversion on 2nd parameter. (windows only)
4917
Georg Brandl222e2082010-08-01 22:27:39 +00004918- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004919 in a redirect.
4920
Brett Cannonabe423e2008-08-16 21:47:07 +00004921- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004922 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004923
Facundo Batistaeb90b782008-08-16 14:44:07 +00004924- Issue #2776: fixed small issue when handling an URL with double slash
4925 after a 302 response in the case of not going through a proxy.
4926
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004927- Issue #2676: in the email package, content-type parsing was hanging on
4928 pathological input because of quadratic or exponential behaviour of a
4929 regular expression.
4930
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004931- Issue #3476: binary buffered reading through the new "io" library is now
4932 thread-safe.
4933
Brett Cannonbf3157b2008-08-14 05:00:03 +00004934- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4935 since mimetools itself is deprecated. Because modules are cached, all
4936 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4937
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004938- Issue #3134: shutil referenced undefined WindowsError symbol.
4939
Robert Schuppenies14646332008-08-10 11:01:53 +00004940- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4941 menu entries were not deleted.
4942
Brett Cannon83e81842008-08-09 23:30:55 +00004943- Copied the implementation of reduce() to _functools.reduce() to have a
4944 version that did not raise a DeprecationWarning under -3.
4945
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004946- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4947 a MemoryError rather than silently stop the iteration.
4948
Guido van Rossum59ce9012008-08-09 14:55:34 +00004949- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4950 to _sre.compile() will now be rejected. This should not affect anybody
4951 since the re.compile() function never generates invalid re-bytecode.
4952
Skip Montanaroa032bf42008-08-08 22:52:51 +00004953- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4954 upon first access it can be automatically initialized from the csv file if
4955 it wasn't initialized during instantiation.
4956
Brett Cannon3aa2a492008-08-06 22:28:09 +00004957- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4958 the reload() built-in has been removed.
4959
Brett Cannon7e30b672008-08-04 21:52:25 +00004960- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004961 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004962 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4963 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4964 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4965 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4966 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004967
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004968- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4969 raised an AttributeError.
4970
Benjamin Peterson01a24322008-07-28 23:35:27 +00004971- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004972 asking for a specific length. This problem only affected files opened
4973 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004974
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004975- Issue #3449: Update decimal module to use most recent specification
4976 (v. 1.68) and tests (v. 2.58) from IBM.
4977
Georg Brandl222e2082010-08-01 22:27:39 +00004978- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

4982
Georg Brandlf9efabb2008-07-23 15:16:45 +00004983- Deprecate the "ast" parser function aliases.
4984
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004985- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4986
4987- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4988 invalid arguments.
4989
4990- Issue #3302: Fix several crashes when calling locale's gettext functions
4991 with None arguments.

4997
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004998- Issue #3394: zipfile.writestr sets external attributes when passed a
4999 file name rather than a ZipInfo instance, so files are extracted with
5000 mode 0600 rather than 000 under Unix.
5001
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005002- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5003 argument in python 2.5, this broke code that subclassed Popen to include its
5004 own poll method. Fixed my moving _deadstate to an _internal_poll method.
5005
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00005006Build

5012-------------
5013
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005014- Issue #2235: the C API function PyObject_HashNotImplemented and its
5015 interaction with the tp_hash slot (added in 2.6b2) are now documented
5016
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005017- Issue #643841: The language reference now provides more detailed
5018 coverage of the lookup process for special methods. The disclaimers
5019 regarding lack of coverage of new-style classes have also been
5020 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005023What's New in Python 2.6 beta 2?
5024================================
5025
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005026*Release date: 17-Jul-2008*
5027
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005028Core and Builtins
5029-----------------
5030
Georg Brandl3e483f62008-07-16 22:57:41 +00005031- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5032 its methods now allow for items objects that can be converted to
5033 an integer using operator.index().
5034
Mark Dickinson64b7e502008-07-16 09:40:03 +00005035- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5036 produced a ValueError instead of giving the correct float.
5037
Eric Smitha5fa5a22008-07-16 00:11:49 +00005038- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5039 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5040
Mark Dickinson7103aa42008-07-15 19:08:33 +00005041- Issue #3008: the float type has a new instance method 'float.hex'
5042 and a new class method 'float.fromhex' to convert floating-point
5043 numbers to and from hexadecimal strings, respectively.
5044
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005045- Issue #2235: __hash__ is once again inherited by default. To allow
5046 collections.Hashable to remain meaningful in the presence of the
5047 default hash implementation (object.__hash__), it is now possible
5048 to explicit block inheritance of hash by setting __hash__=None at
5049 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5050 level.
5051
Nick Coghlanb028f502008-07-13 14:52:36 +00005052- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5053 the parent module cannot be found while performing an absolute import.
5054 This means that an incorrectly defined __package__ attribute will
5055 now only prevent relative imports in that module rather than causing
5056 all imports from that module to fail.
5057
Nick Coghlan14ff9942008-07-08 14:21:42 +00005058- Issue #2517: Allow unicode messages in Exceptions again by correctly
5059 bypassing the instance dictionary when looking up __unicode__ on
5060 new-style classes.
5061
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005062- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5063 set to a custom object whose write() method happens to install
5064 another file in sys.stdout.
5065
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005066- Issue #3088: Corrected a race condition in classes derived from
5067 threading.local: the first member set by a thread could be saved in
5068 another thread's dictionary.
5069
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005070- Issue #3004: Minor change to slice.indices(): the start and stop
5071 arguments are now treated identically, making the behaviour easier
5072 to describe and understand. For example, slice(None, -10,
5073 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5074 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5075 10, -1).
5076
Georg Brandl278fc502008-07-19 12:46:12 +00005077- Issue #3219: Calling a function with repeated keyword arguments,
5078 f(a=2, a=23), would not cause a syntax error. This was a regression
5079 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005080
Georg Brandl278fc502008-07-19 12:46:12 +00005081- Issue #2862: Make int and float freelist management consistent with
5082 other freelists. Changes their CompactFreeList apis into
5083 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005084

Thomas Heller57adf222008-08-14 19:10:48 +00005088- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5089 api functions without holding the GIL, which could lead to a fatal
5090 error when they failed.
5091
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005092- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005100- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5101 ForkingPickler.register() to resolve conflict with ctypes.
5102
Vinay Sajip51e65192008-07-18 09:01:10 +00005103- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

5106 a valid dlerror() message.
5107
Thomas Heller2bad6572008-07-15 17:19:50 +00005108- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5109 incomplete structure was created.

5528 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005529 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005530
5531 This is controlled by the configure argument ``--with-universal-archs``:
5532
5533 - ``--with-universal-archs=all``: install 4-way universal
5534
5535 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5536
5537 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5538
5539 This option should be used in combination with ``--enable-universalsdk=``.
5540
5541 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

5578 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005579
Christian Heimese74c8f22008-04-19 02:23:57 +00005580- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5581
Georg Brandl3ee81df2008-05-17 18:14:43 +00005582- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
5583 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00005584
Georg Brandl3ee81df2008-05-17 18:14:43 +00005585- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00005591- Issue #1631171: Re-implement the 'warnings' module in C (the
5592 original Python code has been kept as backup). This will allow for
5593 using the 'warning's machinery in such places as the parser where
5594 use of pure Python code is not possible. Both the ``showarning()``
5595 and ``formatwarning()`` gain an optional 'line' argument which is
5596 not called by default for backwards-compatibility reasons. Setting
5597 ``warnings.showwarning()`` to an implementation that lacks support
5598 for the ``line`` argument will raise a DeprecationWarning.

Thomas Hellerbf027c42008-04-24 18:14:19 +00005621 reference to themselves.
5622
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005623- The getpass module has been improved on Unix. It now uses /dev/tty
5624 by default and uses stderr instead of stdout. A GetPassWarning is
5625 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00005626

Georg Brandl3ee81df2008-05-17 18:14:43 +00005640- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005641 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005661- Issue #2550: The approach used by client/server code for obtaining
5662 ports to listen on in network-oriented tests has been refined in an
5663 effort to facilitate running multiple instances of the entire
5664 regression test suite in parallel without issue.
5665 test_support.bind_port() has been fixed such that it will always
5666 return a unique port -- which wasn't always the case with the
5667 previous implementation, especially if socket options had been set
5668 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5669 new implementation of bind_port() will actually raise an exception
5670 if it is passed an AF_INET/SOCK_STREAM socket with either the
5671 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5672 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5673 the socket it's been passed. This currently only applies to
5674 Windows. This option prevents any other sockets from binding to the
5675 host/port we've bound to, thus removing the possibility of the
5676 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5677 when a second SOCK_STREAM socket binds and accepts to a host/port
5678 that's already been bound by another socket. The optional preferred
5679 port parameter to bind_port() has been removed. Under no
5680 circumstances should tests be hard coding ports!
5681
5682 test_support.find_unused_port() has also been introduced, which will
5683 pass a temporary socket object to bind_port() in order to obtain an
5684 unused port. The temporary socket object is then closed and
5685 deleted, and the port is returned. This method should only be used
5686 for obtaining an unused port in order to pass to an external program
5687 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5688 a parameter to a server-oriented class that doesn't give you direct
5689 access to the underlying socket used.
5690
5691 Finally, test_support.HOST has been introduced, which should be used
5692 for the host argument of any relevant socket calls (i.e. bind and
5693 connect).

5969
Fred Drakea8ee94b2008-03-01 02:45:07 +00005970- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005971 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005972
Georg Brandlad61bc82008-02-23 15:11:18 +00005973- Issue #2067: file.__exit__() now calls subclasses' close() method.
5974
5975- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005976
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005977- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005978 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005979
Eric Smitha73fbe72008-02-23 03:09:44 +00005980- Added the future_builtins module, which contains hex() and oct().
5981 These are the PEP 3127 version of these functions, designed to be
5982 compatible with the hex() and oct() builtins from Python 3.0. They
5983 differ slightly in their output formats from the existing, unchanged
5984 Python 2.6 builtins. The expected usage of the future_builtins
5985 module is:
5986 from future_builtins import hex, oct
5987
Eric Smith7ef40bf2008-02-20 23:34:22 +00005988- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5989 exponents for exponents with absolute value < 100. Follows C99
5990 standard. This is a change on Windows, which would use 3 digits.
5991 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5992 so that any alterations it does to the resulting string will be
5993 available in stringlib/formatter.h (for float.__format__).
5994
Eric Smith5a3c1352008-02-19 13:21:56 +00005995- Implemented PEP 3101, Advanced String Formatting. This adds a new
5996 builtin format(); a format() method for str and unicode; a
5997 __format__() method to object, str, unicode, int, long, float, and
5998 datetime; the class string.Formatter; and the C API
5999 PyObject_Format().
6000
Georg Brandl3ee81df2008-05-17 18:14:43 +00006001- Fixed several potential crashes, all caused by specially crafted
6002 __del__ methods exploiting objects in temporarily inconsistent
6003 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006004
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006005- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006006 prevent a possible crash: an Abstract Base Class would try to access
6007 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006008
Georg Brandl3ee81df2008-05-17 18:14:43 +00006009- Fixed repr() and str() of complex numbers with infinity or nan as
6010 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006011
Georg Brandl3ee81df2008-05-17 18:14:43 +00006012- Clear all free lists during a gc.collect() of the highest generation
6013 in order to allow pymalloc to free more arenas. Python may give back
6014 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006015
Georg Brandl3ee81df2008-05-17 18:14:43 +00006016- Issue #2045: Fix an infinite recursion triggered when printing a
6017 subclass of collections.defaultdict, if its default_factory is set
6018 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006019
Christian Heimesf75dbef2008-02-08 00:11:31 +00006020- Fixed a minor memory leak in dictobject.c. The content of the free
6021 list was not freed on interpreter shutdown.
6022
Georg Brandl21e99f42010-03-07 15:23:59 +00006023- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006024 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006025
Georg Brandl3ee81df2008-05-17 18:14:43 +00006026- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6027 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006028 to compact the internal free lists of pre-allocted ints and floats.
6029
Georg Brandl3ee81df2008-05-17 18:14:43 +00006030- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6031 calls. Python expected the return type int but the fork familie
6032 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006033
Georg Brandl3ee81df2008-05-17 18:14:43 +00006034- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6035 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006036
Georg Brandl3ee81df2008-05-17 18:14:43 +00006037- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6038 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006039
Georg Brandl3ee81df2008-05-17 18:14:43 +00006040- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6041 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006042
Georg Brandl3ee81df2008-05-17 18:14:43 +00006043- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6044 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006045
Georg Brandl3ee81df2008-05-17 18:14:43 +00006046- Patch #1473257: generator objects gain a gi_code attribute. This is
6047 the same object as the func_code attribute of the function that
6048 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006049
Georg Brandl3ee81df2008-05-17 18:14:43 +00006050- Issue #1920: "while 0" statements were completely removed by the
6051 compiler, even in the presence of an "else" clause, which is
6052 supposed to be run when the condition is false. Now the compiler
6053 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006054
Guido van Rossumeead05f2008-01-24 18:21:02 +00006055- A few crashers fixed: weakref_in_del.py (issue #1377858);
6056 loosing_dict_ref.py (issue #1303614, test67.py);
6057 borrowed_ref_[34].py (not in tracker).
6058
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006059- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006060 suppressed while an extension is loaded by calling SetErrorMode in
6061 dynload_win.c. The error is still reported properly.
6062
Georg Brandl3ee81df2008-05-17 18:14:43 +00006063- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006064 several extension methods and modules do not work without unicode
6065 support.
6066
Georg Brandl26543b12008-01-21 18:36:51 +00006067- Issue #1882: when compiling code from a string, encoding cookies in the
6068 second line of code were not always recognized correctly.
6069
Georg Brandl14404b62008-01-19 19:27:05 +00006070- Issue #1679: "0x" was taken as a valid integer literal.
6071
Georg Brandl6caad7d2008-01-26 14:19:22 +00006072- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006073 added.
6074
Christian Heimesc94e2b52008-01-14 04:13:37 +00006075- sys.float_info / PyFloat_GetInfo: The floating point information
6076 object was converted from a dict to a specialized structseq object.
6077
Georg Brandl3ee81df2008-05-17 18:14:43 +00006078- Patch #1816: Added sys.flags structseq. It exposes the status of
6079 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006080
Georg Brandl3ee81df2008-05-17 18:14:43 +00006081- Objects/structseq.c: Implemented new structseq representation. The
6082 patch makes structseqs (e.g. the return value of os.stat) more
6083 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006084
Georg Brandl3ee81df2008-05-17 18:14:43 +00006085- Patch #1700288: added a type attribute cache that caches method
6086 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006087
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006088- Bug #1776: __import__() no longer accepts filenames on any platform.

6092
Georg Brandl3ee81df2008-05-17 18:14:43 +00006093- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6094 envvar and sys.dont_write_bytecode attribute. All these can be set
6095 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006096
Georg Brandl3ee81df2008-05-17 18:14:43 +00006097- Improve some exception messages when Windows fails to load an
6098 extension module. Now we get for example '%1 is not a valid Win32
6099 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006100
Georg Brandl3ee81df2008-05-17 18:14:43 +00006101- Bug #1481296: Fixed long(float('nan')) != 0L.

6104 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006105
Christian Heimes0a8143f2007-12-18 23:22:54 +00006106- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006107 and INF. float("nan"), float("inf") and float("-inf") now work on
6108 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006109
Georg Brandl3ee81df2008-05-17 18:14:43 +00006110- Compiler now generates simpler and faster code for dictionary
6111 literals. The oparg for BUILD_MAP now indicates an estimated
6112 dictionary size. There is a new opcode, STORE_MAP, for adding
6113 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006147- Issue #1265: Fix a problem with sys.settrace, if the tracing
6148 function uses a generator expression when at the same time the
6149 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006150
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006151- sets and frozensets now have an isdisjoint() method.

Georg Brandl21e99f42010-03-07 15:23:59 +00006157- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006158 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6159 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006160
Georg Brandl3ee81df2008-05-17 18:14:43 +00006161- Issue #1686386: Tuple's tp_repr did not take into account the
6162 possibility of having a self-referential tuple, which is possible
6163 from C code. Nor did object's tp_str consider that a type's tp_str
6164 could do something that could lead to an inifinite recursion.
6165 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6166 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006167
Georg Brandl3ee81df2008-05-17 18:14:43 +00006168- Issue #1164: It was possible to trigger deadlock when using the
6169 'print' statement to write to a file since the GIL was not released
6170 as needed. Now PyObject_Print() does the right thing along with
6171 various tp_print implementations of the built-in types and those in
6172 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006174- Issue #1147: Exceptions were directly allowing string exceptions in
6175 their throw() method even though string exceptions no longer
6176 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006178- Issue #1096: Prevent a segfault from getting the repr of a very
6179 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00006181- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006182 PyObject_Call() never calling back out to Python code to trigger
6183 recursion depth updates/checks. Required the creation of a static
6184 RuntimeError instance in case normalizing an exception put the
6185 recursion check value past its limit. Fixes crashers
6186 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006201- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006202 __*__ attributes. (Some already existed, e.g., __doc__ and
6203 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006204
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006205- Add -3 option to the interpreter to warn about features that are
6206 deprecated and will be changed/removed in Python 3.0.
6207
Georg Brandl2134e752007-05-21 20:34:16 +00006208- Patch #1686487: you can now pass any mapping after '**' in function
6209 calls.
6210
Collin Winter62903052007-05-18 23:11:24 +00006211- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006212 "except E as target:". This is to provide forwards compatibility
6213 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006214
Brett Cannon229cee22007-05-05 01:34:02 +00006215- Deprecate BaseException.message as per PEP 352.
6216
Georg Brandl3ee81df2008-05-17 18:14:43 +00006217- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006218 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006220- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006221 setting a plain string, ie don't expand to single letter identifiers.
6222
Raymond Hettinger13936692007-04-11 18:40:58 +00006223- Request #1191699: Slices can now be pickled.
6224
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006225- Request #1193128: str.translate() now allows a None argument for
6226 translations that only remove characters without re-mapping the
6227 remaining characters.
6228
Georg Brandl5cb76c12007-03-21 09:00:39 +00006229- Patch #1682205: a TypeError while unpacking an iterable is no longer
6230 masked by a generic one with the message "unpack non-sequence".
6231
Neal Norwitzaa754b72007-03-21 06:39:48 +00006232- Remove unused file Python/fmod.c.
6233
Guido van Rossum143b5642007-03-23 04:58:42 +00006234- Bug #1683368: The object.__init__() and object.__new__() methods are
6235 now stricter in rejecting excess arguments. The only time when
6236 either allows excess arguments is when it is not overridden and the
6237 other one is. For backwards compatibility, when both are
6238 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006239 warning later). Also, type.__init__() insists on the same signature
6240 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006241
Georg Brandl3ee81df2008-05-17 18:14:43 +00006242- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6243 object to complex using its __complex__() method before falling back
6244 to the __float__() method. Therefore, the functions in the cmath
6245 module now can operate on objects that define a __complex__()
6246 method.

6257 its type.

6263
Georg Brandl7b9c5552007-03-12 14:30:05 +00006264- Bug #1678647: write a newline after printing an exception in any
6265 case, even when converting the value to a string failed.
6266
Georg Brandl871f1bc2007-03-12 13:17:36 +00006267- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006268 its argument, if it exists. If not, it will work like before. This
6269 allows customizing the output of dir() in the presence of a
6270 __getattr__().

6279 parthensized forms. This means complex(repr(x)) now works instead of
6280 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006281
Georg Brandlaa2321b2007-03-07 00:40:28 +00006282- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006283 makes the filenames the warning module prints much more sensible
6284 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006285
Georg Brandl49aafc92007-03-07 00:34:46 +00006286- Variant of patch #697613: don't exit the interpreter on a SystemExit
6287 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006288 variable is given, but break into the interactive interpreter just
6289 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006297- Patch #1674228: when assigning a slice (old-style), check for the
6298 sq_ass_slice instead of the sq_slice slot.
6299
Georg Brandl3ee81df2008-05-17 18:14:43 +00006300- When printing an unraisable error, don't print exceptions. before
6301 the name. This duplicates the behavior whening normally printing
6302 exceptions.

6911 Python would crash instead of raising an error.
6912

6928 accepted in TestSuite.addTest(). This should cause no
6929 incompatibility since it never made sense with ordinary subclasses
6930 -- the failure just occurred later, with a more cumbersome
6931 exception.

7214 obtained from the TLS negotiation itself. Patch contributed by Bill
7215 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007216
Georg Brandl3ee81df2008-05-17 18:14:43 +00007217- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007218 that the SMTP.starttls() caller no longer needs to call ehlo()
7219 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007220 does not claim to support starttls. Adds the
7221 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7302 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7303 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007320 time so that opening a database previously created with the DB_DUP
7321 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7322 opens. Specifically: dictionary assignment to a DB object will
7323 replace all values for a given key when the database allows
7324 duplicate values. DB users should use DB.put(k, v) when they want
7325 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007326

7332 characters with ASCII value less than 32. Also, it correctly quotes
7333 dots only if they occur on a single line, as opposed to the previous
7334 behavior of quoting dots if they are the second character of any
7335 line.

7658-----
7659
Georg Brandl3ee81df2008-05-17 18:14:43 +00007660- Unified naming convention for free lists and their limits. All free
7661 lists in Object/ are named ``free_list``, the counter ``numfree``
7662 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7663 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007664
Georg Brandl3ee81df2008-05-17 18:14:43 +00007665- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7666 to ``PyTuple_SetItem``, it can be used to populate a brand new
7667 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007668
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007669- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007671- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7672 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7673 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007674
7675- Patch #1720595: add T_BOOL to the range of structmember types.
7676
7677- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7678 ``PyFloat_GetInfo()`` to the float API.
7679
Georg Brandl3ee81df2008-05-17 18:14:43 +00007680- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7681 of w# format code incorrectly truncated the length to an int, even
7682 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7683 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007684
Georg Brandl3ee81df2008-05-17 18:14:43 +00007685- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7686 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007687
Georg Brandl3ee81df2008-05-17 18:14:43 +00007688- PEP 3123: Provide forward compatibility with Python 3.0, while
7689 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7690 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007691
Georg Brandl3ee81df2008-05-17 18:14:43 +00007692- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7693 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007694
7695- Patch #1733960: Allow T_LONGLONG to accept ints.
7696
7697- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7698
Christian Heimes000a0742008-01-03 22:16:32 +00007699- Added a new API function ``PyImport_ImportModuleNoBlock``.

7702
7703- Fix some leftovers from the conversion from int to Py_ssize_t
7704 (relevant to strings and sequences of more than 2**31 items).
7705
7706- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7707 outside of pystate.c and should not be necessary.
7708
Georg Brandl3ee81df2008-05-17 18:14:43 +00007709- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7710 absolute imports. In earlier versions they might have used relative
7711 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007712
Georg Brandl3ee81df2008-05-17 18:14:43 +00007713- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7714 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007715
Georg Brandl3ee81df2008-05-17 18:14:43 +00007716- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7717 macro so it can be used as an expression.

7722
Georg Brandl3ee81df2008-05-17 18:14:43 +00007723- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7724 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7725 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7726 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007727
Georg Brandl3ee81df2008-05-17 18:14:43 +00007728- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00007741- Removed the macfs module. It had been deprecated since Python 2.5.
7742 This lead to the deprecation of macostools.touched() as it relied
7743 solely on macfs and was a no-op under OS X.
