Mark Dickinsondbbed042011-09-19 16:38:08 +010036- Issue #12973: Fix overflow checks that invoked undefined behaviour in
37 int.__pow__. These overflow checks were causing int.__pow__ to produce
38 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010039 compiler optimizing the check away. Also fix similar overflow checks
40 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
41 bugs caused test failures with recent versions of Clang.

53 cleared by the garbage collector. This fixes a segfault when an instance
54 and its type get caught in a reference cycle, and the instance's
55 deallocator calls one of the methods on the type (e.g. when subclassing

Ned Deily87e82bb2011-06-28 19:52:59 -0700237- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
238 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
239 interpreter process. This could cause failures in non-Distutils subprocesses
240 and was unreliable since tests or user programs could modify the interpreter
241 environment after Distutils set it. Instead, have Distutils set the the
242 deployment target only in the environment of each build subprocess. It is
243 still possible to globally override the default by setting
244 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
245 greater or equal to the default value, the value with which the interpreter
246 was built.

273
Barry Warsawc5643282011-07-19 17:06:30 -0400274- sys.setcheckinterval() now updates the current ticker count as well as
275 updating the check interval, so if the user decreases the check interval,
276 the ticker doesn't have to wind down to zero from the old starting point
277 before the new interval takes effect. And if the user increases the
278 interval, it makes sure the new limit takes effect right away rather have an
279 early task switch before recognizing the new interval.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001640- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1641 start byte and the continuation byte(s) are now considered invalid, instead
1642 of the number of bytes specified by the start byte.
1643 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1644 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1645 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

1655 objects. (1) The comparison could incorrectly return True in some cases
1656 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1657 (2) The comparison raised an OverflowError for large integers, leading

1853 operation raises multiple signals and more than one of those signals is
1854 trapped, the specification determines the order in which the signals should be

Georg Brandlfee0f442010-05-22 21:26:21 +00002000- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002001 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2002 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2003 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2023Core and Builtins
2024-----------------
2025
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002026- Issue #7301: Add environment variable $PYTHONWARNINGS.
2027
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002028- Issue #8329: Don't return the same lists from select.select when no fds are
2029 changed.
2030
Georg Brandlfee0f442010-05-22 21:26:21 +00002031- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002032 on 64-bit machines. The shift count for either left or right shift is
2033 permitted to be up to sys.maxsize.
2034
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002035- Ensure that tokenization of identifiers is not affected by locale.
2036
Georg Brandlfee0f442010-05-22 21:26:21 +00002037- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002038
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002039- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2040
Georg Brandlfee0f442010-05-22 21:26:21 +00002041- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2042 with a non-empty format string. This is an effort to future-proof user
2043 code. If a derived class does not currently implement __format__ but later
2044 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002045 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002046 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002047
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002048- Issue #8268: Old-style classes (not just instances) now support weak
2049 references.
2050
Georg Brandlfee0f442010-05-22 21:26:21 +00002051- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2052 is set.

2060
Victor Stinner66644262010-03-10 22:30:19 +00002061- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002062 (SIGINT). If an error occurs while importing the site module, the error is
2063 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002064 module.

2072
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002073- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002074 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2075 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002077- Issue #8310: Allow dis to examine new style classes.
2078
Georg Brandlfee0f442010-05-22 21:26:21 +00002079- Issue #8257: The Decimal construct now accepts a float instance directly,
2080 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002081
2082 >>> Decimal(1.1)
2083 Decimal('1.100000000000000088817841970012523233890533447265625')
2084
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002085- collections.Counter() now supports a subtract() method.
2086
Georg Brandlfee0f442010-05-22 21:26:21 +00002087- The functools module now has a total_ordering() class decorator to simplify
2088 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002089
Georg Brandlfee0f442010-05-22 21:26:21 +00002090- The functools module also adds cmp_to_key() as a tool to transition old-style
2091 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002092
Georg Brandlfee0f442010-05-22 21:26:21 +00002093- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2094 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002095
Georg Brandlfee0f442010-05-22 21:26:21 +00002096- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2097 InvalidOperation instead of returning False. (Comparisons involving a quiet
2098 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2099 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002100
Georg Brandlfee0f442010-05-22 21:26:21 +00002101- Issue #2531: Comparison operations between floats and Decimal instances now
2102 return a result based on the numeric values of the operands; previously they
2103 returned an arbitrary result based on the relative ordering of id(float) and
2104 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002105
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002106- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002107 argument `-` which tells it to read files to compile from stdin. Each line is
2108 read on demand and the named file is compiled immediately. (Original patch by
2109 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002110
Georg Brandlfee0f442010-05-22 21:26:21 +00002111- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2112 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002114- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2115 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002116 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002117
Georg Brandlfee0f442010-05-22 21:26:21 +00002118- Comparisons using one of <, <=, >, >= between a complex instance and a
2119 Fractions instance now raise TypeError instead of returning True/False. This
2120 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2121 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002122
Michael Foorde6410c52010-03-29 20:04:23 +00002123- Addition of ``WeakSet`` to the ``weakref`` module.

2131
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002132- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002133 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2134 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002135
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002136- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2137 deprecated.
2138
Georg Brandlfee0f442010-05-22 21:26:21 +00002139- Issue #7860: platform.uname now reports the correct 'machine' type when Python

2147 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00002148

2153 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
2154 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002176- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002177 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2178 log file to compute the next rollover time. If the log file does not exist,
2179 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002180
Georg Brandlba83f822010-03-14 09:50:54 +00002181- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00002189- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2190 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2191 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002220- Issue #8300: When passing a non-integer argument to struct.pack with any
2221 integer format code, struct.pack first attempts to convert the non-integer
2222 using its __index__ method. If that method is non-existent or raises
2223 TypeError it goes on to try the __int__ method, as described below.
2224
Georg Brandlba83f822010-03-14 09:50:54 +00002225- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2226 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2227 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002228 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2229 inconsistent: __int__ was used for some integer codes but not for others, and
2230 the set of integer codes for which it was used differed between native packing

2463 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002464 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00002539 file position when calling `truncate()`. It would previously change the file
2540 position to the given argument, which goes against the tradition of

2544 class used to represent files stored inside an archive. The new
2545 implementation is significantly faster and can be wrapped in a
2546 ``io.BufferedReader`` object for more speedups. It also solves an issue
2547 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2560 encoded string for them. This ensures that the upload and register commands
2561 send the correct values to PyPI without any error.

2636-----------------
2637
Georg Brandlba83f822010-03-14 09:50:54 +00002638- The ``__complex__()`` method is now looked up on the class of instances to
2639 make it consistent with other special methods.

2643
Mark Dickinson1b34d252010-01-01 17:27:30 +00002644- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002645 DeprecationWarning when passed a float argument where an integer was expected.
2646 These functions and methods now raise TypeError instead. The majority of the
2647 effects of this change are in the extension modules, but some core functions
2648 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2649 and many unicode/str methods.

2663 of integers: the result of a/b is now correctly rounded for ints a and b (at
2664 least on IEEE 754 platforms), and in particular does not depend on the
2665 internal representation of a long.

2673
Georg Brandlba83f822010-03-14 09:50:54 +00002674 These executables now work properly with the arch(1) command: ``arch -ppc
2675 python`` will start a universal binary version of python in PPC mode (unlike

2816 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002817
Georg Brandlba83f822010-03-14 09:50:54 +00002818- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2819 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00002820
Georg Brandlba83f822010-03-14 09:50:54 +00002821- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
2822 1e-100 used to raise OverflowError, but now gives the requested 120
2823 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002831
Georg Brandlba83f822010-03-14 09:50:54 +00002832- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2833 decimal string that's guaranteed to round back to x under correct rounding
2834 (with round-half-to-even rounding mode). Previously it gave a string based on
2835 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2836 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2837 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002838
Georg Brandlba83f822010-03-14 09:50:54 +00002839- Issue #7117: On almost all platforms: float-to-string and string-to-float
2840 conversions within Python are now correctly rounded. Places these conversions
2841 occur include: str for floats and complex numbers; the float and complex
2842 constructors; old-style and new-style numeric formatting; serialization and
2843 deserialization of floats and complex numbers using marshal, pickle and json;
2844 parsing of float and imaginary literals in Python code; Decimal-to-float
2845 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002846
Georg Brandlba83f822010-03-14 09:50:54 +00002847 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2848 providing correctly-rounded strtod and dtoa C functions. This code is
2849 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2850 the C compiler. There may be a small number of platforms on which correct
2851 operation of this code cannot be guaranteed, so the code is not used: notably,
2852 this applies to platforms where the C double format is not IEEE 754 binary64,
2853 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2854 and Python's configure script is unable to determine how to change the FPU
2855 precision. On these platforms conversions use the platform strtod and dtoa,
2856 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002857
Georg Brandlba83f822010-03-14 09:50:54 +00002858- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2859 uses the correctly-rounded string <-> float conversions described above (when
2860 available), and so produces correctly rounded results that will display nicely
2861 under the float repr. There are two related small changes: (1) round now
2862 accepts any class with an ``__index__()`` method for its second argument (but
2863 no longer accepts floats for the second argument), and (2) an excessively
2864 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2865 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003007
Georg Brandlba83f822010-03-14 09:50:54 +00003008 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3009 (2) parsing of strings representing infinities and nans was locale aware; and
3010 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003012- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3013 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3014 but with at least one decimal point and with a default precision
3015 of 12. Previously, the behavior the same but with a default precision of 6.
3016 This more closely matches ``str()``, and reduces surprises when adding
3017 alignment flags to the empty presentation type. This also affects the new
3018 complex.__format__ in the same way.
3019
3020- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3021 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00003083 untrackable objects are not tracked by the garbage collector. This can reduce

3092 internal representation of integers, for performance reasons. Base 2**30 is
3093 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandl6425a2f2008-12-28 11:54:53 +00003181- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003182 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00003183
Skip Montanarof205c132008-12-23 03:30:15 +00003184- Added test case to ensure attempts to read from a file opened for writing
3185 fail.
3186
Georg Brandlba83f822010-03-14 09:50:54 +00003187- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print

Georg Brandlba83f822010-03-14 09:50:54 +00003201- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3202 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3203 instances. On a typical machine this saves 3 bytes of memory (on average) per
3204 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003206- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3207 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3208 instead of throwing a MemoryError.
3209
Georg Brandlba83f822010-03-14 09:50:54 +00003210- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00003213- Issue #4367: Python would segfault during compiling when the unicodedata

3215
Georg Brandlba83f822010-03-14 09:50:54 +00003216- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3217 file objects with closefd=False. The file descriptor is still kept open but
3218 the file object behaves like a closed file. The ``FileIO`` object also got a
3219 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003221- Issue #4348: Some bytearray methods returned that didn't cause any change to
3222 the bytearray, returned the same bytearray instead of a copy.
3223
Georg Brandlba83f822010-03-14 09:50:54 +00003224- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00003236- Issue #4209: Enabling unicode_literals and the print_function in the same
3237 __future__ import didn't work.
3238
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003239- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003240 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003241
Georg Brandlba83f822010-03-14 09:50:54 +00003242- On windows, ``os.chdir()`` given unicode was not working if
3243 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3244 this code path is really executed because I cannot move to such directory on
3245 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003246
Georg Brandlba83f822010-03-14 09:50:54 +00003247- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3248 element is temporarily replaced with an equivalent frozenset. But the
3249 eventual KeyError would always report the empty ``frozenset()`` as the missing
3250 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003267- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3268 returned them on 64bit platforms.
3269
Walter Dörwalded960ac2009-05-03 22:36:33 +00003270- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3271 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3272 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3273 of using the replace error handler in PyUnicode_DecodeUTF8().
3274
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003275- Issue #3739: The unicode-internal encoder now reports the number of characters
3276 consumed like any other encoder (instead of the number of bytes).
3277
Georg Brandlba83f822010-03-14 09:50:54 +00003278- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3279 allocator will be automatically disabled when running under Valgrind. This
3280 gives improved memory leak detection when running under Valgrind, while taking
3281 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004525 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4526 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00004531- Issue #5354: New test support function import_fresh_module() makes it easy to
4532 import both normal and optimised versions of modules. test_heapq and
4533 test_warnings have been adjusted to use it, tests for other modules with both
4534 C and Python implementations in the stdlib can be adjusted to use it over
4535 time.

4544 should cause a test to be skipped are now done using import_module from test
4545 support, which does the conversion.

4647
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004648- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4649 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4650 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4651 ``printf`` function, whereas PyString_FromFormat has an independent
4652 implementation and uses "%zd" on all platforms for size_t values.
4653 This makes a difference on win64, where ``printf`` needs "%Id" to display
4654 64bit values.

4660 object; previously an int would be returned for small values. the __long__
4661 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004671 was correctly parsed but parsing of subsequent arguments failed.
4672
Vinay Sajip35e3b032008-09-01 14:33:59 +00004673- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004674 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4675 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4676 when given a tuple of classes as second argument, were looking up
4677 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4678 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004817What's New in Python 2.6 beta 3?
4818================================
4819
Barry Warsaw07a4a382008-08-21 01:15:08 +00004820*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004821
4822Core and Builtins
4823-----------------
4824
Guido van Rossumf8402962008-08-20 15:01:50 +00004825- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4826 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4827 extensions do not automatically benefit from the class attribute
4828 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4829 to their tp_flags field if they care. This is a backwards
4830 compatibility feature; in 3.0, all types will use the cache by
4831 default.
4832
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004833- Keyword arguments can now follow starred arguments. (``f(a, *args,
4834 keyword=23)`` is now valid syntax.)
4835
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004836- ctypes function pointers that are COM methods have a boolean True
4837 value again.
4838
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004839- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4840 by denying s# to parse objects that have a releasebuffer procedure,
4841 and introducing s*.
4842
Georg Brandl1e13ea92008-08-11 09:07:59 +00004843- Issue #3537: Fix an assertion failure when an empty but presized dict
4844 object was stored in the freelist.
4845
Mark Dickinsonb6467572008-08-04 21:30:09 +00004846- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4847 ValueError consistently across platforms.
4848
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004849- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4850 (64bit Unix, for example), unichr() would truncate its argument and return
4851 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4852
Neal Norwitze7d8be82008-07-31 17:17:14 +00004853- Apply security patches from Apple.
4854
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004855- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4856 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4857
Antoine Pitrou92f82162008-07-25 22:22:08 +00004858- Issue #1819: function calls with several named parameters are now on
4859 average 35% faster (as measured by pybench).
4860
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004861- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4862 the python debugger steps into a class statement: the free variables (local
4863 variables defined in an outer scope) would be deleted from the outer scope.
4864
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004865- Issue #2620: Overflow checking when allocating or reallocating memory
4866 was not always being done properly in some python types and extension
4867 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4868 all been updated to perform better checks and places in the code that
4869 would previously leak memory on the error path when such an allocation
4870 failed have been fixed.
4871
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004872Library
4873-------
4874
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004875- Issue #3612: Added some missing basic types in ctypes.wintypes.
4876
Benjamin Petersone977ad42008-08-20 01:42:01 +00004877- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4878 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4879
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004880- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4881 version reported by these tools does not necessarily follow the python
4882 version numbering scheme, so the module is less strict when parsing it.
4883
Nick Coghlanf70385a2008-08-18 12:42:46 +00004884- Issue #2235: Added Py3k warnings for types which will become unhashable
4885 under the stricter __hash__ inheritance rules in 3.0. Several types
4886 which did not meet the rules for hash invariants and were already
4887 unhashable in 3.0 have now been explicitly flagged as unhashable in
4888 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4889 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4890
Brett Cannon88f801d2008-08-18 00:46:22 +00004891- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4892 imported into the module but exposed as part of the module's API.
4893
Brett Cannon7b96f072008-08-18 00:41:11 +00004894- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4895
Brett Cannon46225e72008-08-18 00:36:52 +00004896- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4897
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004898- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4899
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004900- Issue #3575: Incremental decoder's decode function now takes bytearray
4901 by using 's*' instead of 't#'.
4902
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004903- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004904 fails unicode conversion on 2nd parameter. (windows only)
4905
Georg Brandl222e2082010-08-01 22:27:39 +00004906- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004907 in a redirect.
4908
Brett Cannonabe423e2008-08-16 21:47:07 +00004909- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004910 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004911
Facundo Batistaeb90b782008-08-16 14:44:07 +00004912- Issue #2776: fixed small issue when handling an URL with double slash
4913 after a 302 response in the case of not going through a proxy.
4914
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004915- Issue #2676: in the email package, content-type parsing was hanging on
4916 pathological input because of quadratic or exponential behaviour of a
4917 regular expression.
4918
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004919- Issue #3476: binary buffered reading through the new "io" library is now
4920 thread-safe.
4921
Brett Cannonbf3157b2008-08-14 05:00:03 +00004922- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4923 since mimetools itself is deprecated. Because modules are cached, all
4924 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4925
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004926- Issue #3134: shutil referenced undefined WindowsError symbol.
4927
Robert Schuppenies14646332008-08-10 11:01:53 +00004928- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4929 menu entries were not deleted.
4930
Brett Cannon83e81842008-08-09 23:30:55 +00004931- Copied the implementation of reduce() to _functools.reduce() to have a
4932 version that did not raise a DeprecationWarning under -3.
4933
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004934- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4935 a MemoryError rather than silently stop the iteration.
4936
Guido van Rossum59ce9012008-08-09 14:55:34 +00004937- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4938 to _sre.compile() will now be rejected. This should not affect anybody
4939 since the re.compile() function never generates invalid re-bytecode.
4940
Skip Montanaroa032bf42008-08-08 22:52:51 +00004941- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4942 upon first access it can be automatically initialized from the csv file if
4943 it wasn't initialized during instantiation.
4944
Brett Cannon3aa2a492008-08-06 22:28:09 +00004945- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4946 the reload() built-in has been removed.
4947
Brett Cannon7e30b672008-08-04 21:52:25 +00004948- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004949 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004950 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4951 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4952 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4953 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4954 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004955
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00004956- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
4957 raised an AttributeError.
4958
Benjamin Peterson01a24322008-07-28 23:35:27 +00004959- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00004960 asking for a specific length. This problem only affected files opened
4961 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004962
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004963- Issue #3449: Update decimal module to use most recent specification
4964 (v. 1.68) and tests (v. 2.58) from IBM.
4965
Georg Brandl222e2082010-08-01 22:27:39 +00004966- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00004967

4970
Georg Brandlf9efabb2008-07-23 15:16:45 +00004971- Deprecate the "ast" parser function aliases.
4972
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004973- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
4974
4975- Issue #3303: Fix a crash in locale.strcoll() when calling it with
4976 invalid arguments.
4977
4978- Issue #3302: Fix several crashes when calling locale's gettext functions
4979 with None arguments.
4980

4985
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004986- Issue #3394: zipfile.writestr sets external attributes when passed a
4987 file name rather than a ZipInfo instance, so files are extracted with
4988 mode 0600 rather than 000 under Unix.
4989
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004990- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4991 argument in python 2.5, this broke code that subclassed Popen to include its
4992 own poll method. Fixed my moving _deadstate to an _internal_poll method.
4993
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00004994Build
4995-----

5000-------------
5001
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005002- Issue #2235: the C API function PyObject_HashNotImplemented and its
5003 interaction with the tp_hash slot (added in 2.6b2) are now documented
5004
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005005- Issue #643841: The language reference now provides more detailed
5006 coverage of the lookup process for special methods. The disclaimers
5007 regarding lack of coverage of new-style classes have also been
5008 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005011What's New in Python 2.6 beta 2?
5012================================
5013
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005014*Release date: 17-Jul-2008*
5015
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005016Core and Builtins
5017-----------------
5018
Georg Brandl3e483f62008-07-16 22:57:41 +00005019- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5020 its methods now allow for items objects that can be converted to
5021 an integer using operator.index().
5022
Mark Dickinson64b7e502008-07-16 09:40:03 +00005023- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5024 produced a ValueError instead of giving the correct float.
5025
Eric Smitha5fa5a22008-07-16 00:11:49 +00005026- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5027 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5028
Mark Dickinson7103aa42008-07-15 19:08:33 +00005029- Issue #3008: the float type has a new instance method 'float.hex'
5030 and a new class method 'float.fromhex' to convert floating-point
5031 numbers to and from hexadecimal strings, respectively.
5032
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005033- Issue #2235: __hash__ is once again inherited by default. To allow
5034 collections.Hashable to remain meaningful in the presence of the
5035 default hash implementation (object.__hash__), it is now possible
5036 to explicit block inheritance of hash by setting __hash__=None at
5037 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5038 level.
5039
Nick Coghlanb028f502008-07-13 14:52:36 +00005040- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5041 the parent module cannot be found while performing an absolute import.
5042 This means that an incorrectly defined __package__ attribute will
5043 now only prevent relative imports in that module rather than causing
5044 all imports from that module to fail.
5045
Nick Coghlan14ff9942008-07-08 14:21:42 +00005046- Issue #2517: Allow unicode messages in Exceptions again by correctly
5047 bypassing the instance dictionary when looking up __unicode__ on
5048 new-style classes.
5049
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005050- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5051 set to a custom object whose write() method happens to install
5052 another file in sys.stdout.
5053
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005054- Issue #3088: Corrected a race condition in classes derived from
5055 threading.local: the first member set by a thread could be saved in
5056 another thread's dictionary.
5057
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005058- Issue #3004: Minor change to slice.indices(): the start and stop
5059 arguments are now treated identically, making the behaviour easier
5060 to describe and understand. For example, slice(None, -10,
5061 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5062 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5063 10, -1).
5064
Georg Brandl278fc502008-07-19 12:46:12 +00005065- Issue #3219: Calling a function with repeated keyword arguments,
5066 f(a=2, a=23), would not cause a syntax error. This was a regression
5067 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005068
Georg Brandl278fc502008-07-19 12:46:12 +00005069- Issue #2862: Make int and float freelist management consistent with
5070 other freelists. Changes their CompactFreeList apis into
5071 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005072

5075
Thomas Heller57adf222008-08-14 19:10:48 +00005076- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5077 api functions without holding the GIL, which could lead to a fatal
5078 error when they failed.
5079
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005080- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005088- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5089 ForkingPickler.register() to resolve conflict with ctypes.
5090
Vinay Sajip51e65192008-07-18 09:01:10 +00005091- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

5094 a valid dlerror() message.
5095
Thomas Heller2bad6572008-07-15 17:19:50 +00005096- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5097 incomplete structure was created.

5516 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005517 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005518
5519 This is controlled by the configure argument ``--with-universal-archs``:
5520
5521 - ``--with-universal-archs=all``: install 4-way universal
5522
5523 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5524
5525 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5526
5527 This option should be used in combination with ``--enable-universalsdk=``.
5528
5529 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

5566 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005567
Christian Heimese74c8f22008-04-19 02:23:57 +00005568- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5569
Georg Brandl3ee81df2008-05-17 18:14:43 +00005570- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
5571 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00005572
Georg Brandl3ee81df2008-05-17 18:14:43 +00005573- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00005579- Issue #1631171: Re-implement the 'warnings' module in C (the
5580 original Python code has been kept as backup). This will allow for
5581 using the 'warning's machinery in such places as the parser where
5582 use of pure Python code is not possible. Both the ``showarning()``
5583 and ``formatwarning()`` gain an optional 'line' argument which is
5584 not called by default for backwards-compatibility reasons. Setting
5585 ``warnings.showwarning()`` to an implementation that lacks support
5586 for the ``line`` argument will raise a DeprecationWarning.

5610
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005611- The getpass module has been improved on Unix. It now uses /dev/tty
5612 by default and uses stderr instead of stdout. A GetPassWarning is
5613 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00005614

Georg Brandl3ee81df2008-05-17 18:14:43 +00005628- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005629 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00005649- Issue #2550: The approach used by client/server code for obtaining
5650 ports to listen on in network-oriented tests has been refined in an
5651 effort to facilitate running multiple instances of the entire
5652 regression test suite in parallel without issue.
5653 test_support.bind_port() has been fixed such that it will always
5654 return a unique port -- which wasn't always the case with the
5655 previous implementation, especially if socket options had been set
5656 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5657 new implementation of bind_port() will actually raise an exception
5658 if it is passed an AF_INET/SOCK_STREAM socket with either the
5659 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5660 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5661 the socket it's been passed. This currently only applies to
5662 Windows. This option prevents any other sockets from binding to the
5663 host/port we've bound to, thus removing the possibility of the
5664 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5665 when a second SOCK_STREAM socket binds and accepts to a host/port
5666 that's already been bound by another socket. The optional preferred
5667 port parameter to bind_port() has been removed. Under no
5668 circumstances should tests be hard coding ports!
5669
5670 test_support.find_unused_port() has also been introduced, which will
5671 pass a temporary socket object to bind_port() in order to obtain an
5672 unused port. The temporary socket object is then closed and
5673 deleted, and the port is returned. This method should only be used
5674 for obtaining an unused port in order to pass to an external program
5675 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5676 a parameter to a server-oriented class that doesn't give you direct
5677 access to the underlying socket used.
5678
5679 Finally, test_support.HOST has been introduced, which should be used
5680 for the host argument of any relevant socket calls (i.e. bind and
5681 connect).

5686 test_asynchat and test_socket_ssl.
5687

5689 suite to run in parallel without issue.

5957
Fred Drakea8ee94b2008-03-01 02:45:07 +00005958- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00005959 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00005960
Georg Brandlad61bc82008-02-23 15:11:18 +00005961- Issue #2067: file.__exit__() now calls subclasses' close() method.
5962
5963- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00005964
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005965- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00005966 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00005967
Eric Smitha73fbe72008-02-23 03:09:44 +00005968- Added the future_builtins module, which contains hex() and oct().
5969 These are the PEP 3127 version of these functions, designed to be
5970 compatible with the hex() and oct() builtins from Python 3.0. They
5971 differ slightly in their output formats from the existing, unchanged
5972 Python 2.6 builtins. The expected usage of the future_builtins
5973 module is:
5974 from future_builtins import hex, oct
5975
Eric Smith7ef40bf2008-02-20 23:34:22 +00005976- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5977 exponents for exponents with absolute value < 100. Follows C99
5978 standard. This is a change on Windows, which would use 3 digits.
5979 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5980 so that any alterations it does to the resulting string will be
5981 available in stringlib/formatter.h (for float.__format__).
5982
Eric Smith5a3c1352008-02-19 13:21:56 +00005983- Implemented PEP 3101, Advanced String Formatting. This adds a new
5984 builtin format(); a format() method for str and unicode; a
5985 __format__() method to object, str, unicode, int, long, float, and
5986 datetime; the class string.Formatter; and the C API
5987 PyObject_Format().
5988
Georg Brandl3ee81df2008-05-17 18:14:43 +00005989- Fixed several potential crashes, all caused by specially crafted
5990 __del__ methods exploiting objects in temporarily inconsistent
5991 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005992
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005993- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005994 prevent a possible crash: an Abstract Base Class would try to access
5995 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005996
Georg Brandl3ee81df2008-05-17 18:14:43 +00005997- Fixed repr() and str() of complex numbers with infinity or nan as
5998 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00005999
Georg Brandl3ee81df2008-05-17 18:14:43 +00006000- Clear all free lists during a gc.collect() of the highest generation
6001 in order to allow pymalloc to free more arenas. Python may give back
6002 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006003
Georg Brandl3ee81df2008-05-17 18:14:43 +00006004- Issue #2045: Fix an infinite recursion triggered when printing a
6005 subclass of collections.defaultdict, if its default_factory is set
6006 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006007
Christian Heimesf75dbef2008-02-08 00:11:31 +00006008- Fixed a minor memory leak in dictobject.c. The content of the free
6009 list was not freed on interpreter shutdown.
6010
Georg Brandl21e99f42010-03-07 15:23:59 +00006011- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006012 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006013
Georg Brandl3ee81df2008-05-17 18:14:43 +00006014- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6015 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006016 to compact the internal free lists of pre-allocted ints and floats.
6017
Georg Brandl3ee81df2008-05-17 18:14:43 +00006018- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6019 calls. Python expected the return type int but the fork familie
6020 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006021
Georg Brandl3ee81df2008-05-17 18:14:43 +00006022- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6023 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006024
Georg Brandl3ee81df2008-05-17 18:14:43 +00006025- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6026 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006027
Georg Brandl3ee81df2008-05-17 18:14:43 +00006028- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6029 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006030
Georg Brandl3ee81df2008-05-17 18:14:43 +00006031- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6032 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006033
Georg Brandl3ee81df2008-05-17 18:14:43 +00006034- Patch #1473257: generator objects gain a gi_code attribute. This is
6035 the same object as the func_code attribute of the function that
6036 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006037
Georg Brandl3ee81df2008-05-17 18:14:43 +00006038- Issue #1920: "while 0" statements were completely removed by the
6039 compiler, even in the presence of an "else" clause, which is
6040 supposed to be run when the condition is false. Now the compiler
6041 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006042
Guido van Rossumeead05f2008-01-24 18:21:02 +00006043- A few crashers fixed: weakref_in_del.py (issue #1377858);
6044 loosing_dict_ref.py (issue #1303614, test67.py);
6045 borrowed_ref_[34].py (not in tracker).
6046
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006047- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006048 suppressed while an extension is loaded by calling SetErrorMode in
6049 dynload_win.c. The error is still reported properly.
6050
Georg Brandl3ee81df2008-05-17 18:14:43 +00006051- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006052 several extension methods and modules do not work without unicode
6053 support.
6054
Georg Brandl26543b12008-01-21 18:36:51 +00006055- Issue #1882: when compiling code from a string, encoding cookies in the
6056 second line of code were not always recognized correctly.
6057
Georg Brandl14404b62008-01-19 19:27:05 +00006058- Issue #1679: "0x" was taken as a valid integer literal.
6059
Georg Brandl6caad7d2008-01-26 14:19:22 +00006060- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006061 added.
6062
Christian Heimesc94e2b52008-01-14 04:13:37 +00006063- sys.float_info / PyFloat_GetInfo: The floating point information
6064 object was converted from a dict to a specialized structseq object.
6065
Georg Brandl3ee81df2008-05-17 18:14:43 +00006066- Patch #1816: Added sys.flags structseq. It exposes the status of
6067 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006068
Georg Brandl3ee81df2008-05-17 18:14:43 +00006069- Objects/structseq.c: Implemented new structseq representation. The
6070 patch makes structseqs (e.g. the return value of os.stat) more
6071 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006072
Georg Brandl3ee81df2008-05-17 18:14:43 +00006073- Patch #1700288: added a type attribute cache that caches method
6074 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006075
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006076- Bug #1776: __import__() no longer accepts filenames on any platform.
6077 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006078

6080
Georg Brandl3ee81df2008-05-17 18:14:43 +00006081- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6082 envvar and sys.dont_write_bytecode attribute. All these can be set
6083 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006084
Georg Brandl3ee81df2008-05-17 18:14:43 +00006085- Improve some exception messages when Windows fails to load an
6086 extension module. Now we get for example '%1 is not a valid Win32
6087 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006088
Georg Brandl3ee81df2008-05-17 18:14:43 +00006089- Bug #1481296: Fixed long(float('nan')) != 0L.

6092 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006093
Christian Heimes0a8143f2007-12-18 23:22:54 +00006094- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006095 and INF. float("nan"), float("inf") and float("-inf") now work on
6096 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006097
Georg Brandl3ee81df2008-05-17 18:14:43 +00006098- Compiler now generates simpler and faster code for dictionary
6099 literals. The oparg for BUILD_MAP now indicates an estimated
6100 dictionary size. There is a new opcode, STORE_MAP, for adding
6101 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006135- Issue #1265: Fix a problem with sys.settrace, if the tracing
6136 function uses a generator expression when at the same time the
6137 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006138
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006139- sets and frozensets now have an isdisjoint() method.

6144
Georg Brandl21e99f42010-03-07 15:23:59 +00006145- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006146 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6147 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006148
Georg Brandl3ee81df2008-05-17 18:14:43 +00006149- Issue #1686386: Tuple's tp_repr did not take into account the
6150 possibility of having a self-referential tuple, which is possible
6151 from C code. Nor did object's tp_str consider that a type's tp_str
6152 could do something that could lead to an inifinite recursion.
6153 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6154 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006155
Georg Brandl3ee81df2008-05-17 18:14:43 +00006156- Issue #1164: It was possible to trigger deadlock when using the
6157 'print' statement to write to a file since the GIL was not released
6158 as needed. Now PyObject_Print() does the right thing along with
6159 various tp_print implementations of the built-in types and those in
6160 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006162- Issue #1147: Exceptions were directly allowing string exceptions in
6163 their throw() method even though string exceptions no longer
6164 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006166- Issue #1096: Prevent a segfault from getting the repr of a very
6167 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00006169- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006170 PyObject_Call() never calling back out to Python code to trigger
6171 recursion depth updates/checks. Required the creation of a static
6172 RuntimeError instance in case normalizing an exception put the
6173 recursion check value past its limit. Fixes crashers
6174 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006189- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006190 __*__ attributes. (Some already existed, e.g., __doc__ and
6191 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006192
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006193- Add -3 option to the interpreter to warn about features that are
6194 deprecated and will be changed/removed in Python 3.0.
6195
Georg Brandl2134e752007-05-21 20:34:16 +00006196- Patch #1686487: you can now pass any mapping after '**' in function
6197 calls.
6198
Collin Winter62903052007-05-18 23:11:24 +00006199- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006200 "except E as target:". This is to provide forwards compatibility
6201 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006202
Brett Cannon229cee22007-05-05 01:34:02 +00006203- Deprecate BaseException.message as per PEP 352.
6204
Georg Brandl3ee81df2008-05-17 18:14:43 +00006205- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006206 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006208- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006209 setting a plain string, ie don't expand to single letter identifiers.
6210
Raymond Hettinger13936692007-04-11 18:40:58 +00006211- Request #1191699: Slices can now be pickled.
6212
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006213- Request #1193128: str.translate() now allows a None argument for
6214 translations that only remove characters without re-mapping the
6215 remaining characters.
6216
Georg Brandl5cb76c12007-03-21 09:00:39 +00006217- Patch #1682205: a TypeError while unpacking an iterable is no longer

6219
Neal Norwitzaa754b72007-03-21 06:39:48 +00006220- Remove unused file Python/fmod.c.
6221
Guido van Rossum143b5642007-03-23 04:58:42 +00006222- Bug #1683368: The object.__init__() and object.__new__() methods are
6223 now stricter in rejecting excess arguments. The only time when
6224 either allows excess arguments is when it is not overridden and the
6225 other one is. For backwards compatibility, when both are
6226 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006227 warning later). Also, type.__init__() insists on the same signature
6228 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006229
Georg Brandl3ee81df2008-05-17 18:14:43 +00006230- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6231 object to complex using its __complex__() method before falling back
6232 to the __float__() method. Therefore, the functions in the cmath
6233 module now can operate on objects that define a __complex__()
6234 method.

6245 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00006252- Bug #1678647: write a newline after printing an exception in any
6253 case, even when converting the value to a string failed.
6254
Georg Brandl871f1bc2007-03-12 13:17:36 +00006255- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006256 its argument, if it exists. If not, it will work like before. This
6257 allows customizing the output of dir() in the presence of a
6258 __getattr__().

6267 parthensized forms. This means complex(repr(x)) now works instead of
6268 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006269
Georg Brandlaa2321b2007-03-07 00:40:28 +00006270- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006271 makes the filenames the warning module prints much more sensible
6272 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006273

Georg Brandl0fca97a2007-03-05 22:28:08 +00006285- Patch #1674228: when assigning a slice (old-style), check for the
6286 sq_ass_slice instead of the sq_slice slot.
6287
Georg Brandl3ee81df2008-05-17 18:14:43 +00006288- When printing an unraisable error, don't print exceptions. before

6899 Python would crash instead of raising an error.
6900
Thomas Hellerc2f77252007-03-09 19:21:28 +00006901- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)

6916 accepted in TestSuite.addTest(). This should cause no
6917 incompatibility since it never made sense with ordinary subclasses
6918 -- the failure just occurred later, with a more cumbersome
6919 exception.

7202 obtained from the TLS negotiation itself. Patch contributed by Bill
7203 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007204
Georg Brandl3ee81df2008-05-17 18:14:43 +00007205- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007206 that the SMTP.starttls() caller no longer needs to call ehlo()
7207 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007208 does not claim to support starttls. Adds the
7209 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00007308 time so that opening a database previously created with the DB_DUP
7309 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7310 opens. Specifically: dictionary assignment to a DB object will
7311 replace all values for a given key when the database allows
7312 duplicate values. DB users should use DB.put(k, v) when they want
7313 to store duplicates; not DB[k] = v.

7320 characters with ASCII value less than 32. Also, it correctly quotes
7321 dots only if they occur on a single line, as opposed to the previous
7322 behavior of quoting dots if they are the second character of any
7323 line.

7646-----
7647
Georg Brandl3ee81df2008-05-17 18:14:43 +00007648- Unified naming convention for free lists and their limits. All free
7649 lists in Object/ are named ``free_list``, the counter ``numfree``
7650 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7651 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007652
Georg Brandl3ee81df2008-05-17 18:14:43 +00007653- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7654 to ``PyTuple_SetItem``, it can be used to populate a brand new
7655 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007656
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007657- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007659- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
7660 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
7661 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007662
7663- Patch #1720595: add T_BOOL to the range of structmember types.
7664
7665- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7666 ``PyFloat_GetInfo()`` to the float API.
7667
Georg Brandl3ee81df2008-05-17 18:14:43 +00007668- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7669 of w# format code incorrectly truncated the length to an int, even
7670 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7671 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007672
Georg Brandl3ee81df2008-05-17 18:14:43 +00007673- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
7674 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007675
Georg Brandl3ee81df2008-05-17 18:14:43 +00007676- PEP 3123: Provide forward compatibility with Python 3.0, while
7677 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
7678 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007679
Georg Brandl3ee81df2008-05-17 18:14:43 +00007680- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
7681 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007682
7683- Patch #1733960: Allow T_LONGLONG to accept ints.
7684
7685- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
7686
Christian Heimes000a0742008-01-03 22:16:32 +00007687- Added a new API function ``PyImport_ImportModuleNoBlock``.

7690
7691- Fix some leftovers from the conversion from int to Py_ssize_t
7692 (relevant to strings and sequences of more than 2**31 items).
7693
7694- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7695 outside of pystate.c and should not be necessary.
7696
Georg Brandl3ee81df2008-05-17 18:14:43 +00007697- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7698 absolute imports. In earlier versions they might have used relative
7699 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007700
Georg Brandl3ee81df2008-05-17 18:14:43 +00007701- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7702 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007703
Georg Brandl3ee81df2008-05-17 18:14:43 +00007704- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
7705 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007711- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
7712 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7713 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7714 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007715
Georg Brandl3ee81df2008-05-17 18:14:43 +00007716- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00007729- Removed the macfs module. It had been deprecated since Python 2.5.
7730 This lead to the deprecation of macostools.touched() as it relied
7731 solely on macfs and was a no-op under OS X.
