Ned Deily18fae3f2013-01-31 01:24:55 -08001461- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1462 In particular, fix extension module build failures when trying to use
1463 32-bit-only installer Pythons on systems with Xcode 4 (currently
1464 OS X 10.8, 10.7, and optionally 10.6).
1465 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1466 * Since Xcode 4 removes ppc support, extension module builds now
1467 check for ppc compiler support and by default remove ppc and
1468 ppc64 archs when they are not available.
1469 * Extension module builds now revert to using system installed
1470 headers and libs (/usr and /System/Library) if the SDK used
1471 to build the interpreter is not installed or has moved.
1472 * Try to avoid building extension modules with deprecated
1473 and problematic Apple llvm-gcc compiler. If original compiler
1474 is not available, use clang instead by default.

1826 int.__pow__. These overflow checks were causing int.__pow__ to produce
1827 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001828 compiler optimizing the check away. Also fix similar overflow checks
1829 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Florent Xiclunac2279652012-02-12 14:49:03 +01001898- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001899 has left two versions of customize_compiler, the original in
1900 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001905- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1906 Distutils-based packages with C extension modules may fail because
1907 Apple has removed gcc-4.2, the version used to build python.org
1908 64-bit/32-bit Pythons. If the user does not explicitly override
1909 the default C compiler by setting the CC environment variable,
1910 Distutils will now attempt to compile extension modules with clang
1911 if gcc-4.2 is required but not found. Also as a convenience, if
1912 the user does explicitly set CC, substitute its value as the default
1913 compiler in the Distutils LDSHARED configuration variable for OS X.
1914 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1915 SDK, neither of which are available in Xcode 4. This change does not
1916 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002166- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2167 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2168 interpreter process. This could cause failures in non-Distutils subprocesses
2169 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002170 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002171 deployment target only in the environment of each build subprocess. It is
2172 still possible to globally override the default by setting
2173 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2174 greater or equal to the default value, the value with which the interpreter
2175 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04002203- sys.setcheckinterval() now updates the current ticker count as well as
2204 updating the check interval, so if the user decreases the check interval,
2205 the ticker doesn't have to wind down to zero from the old starting point
2206 before the new interval takes effect. And if the user increases the
2207 interval, it makes sure the new limit takes effect right away rather have an
2208 early task switch before recognizing the new interval.

3190 becoming permanently uncollectable GC garbage. The downside is that
3191 removing __del__ means that the internal doubly-linked list has to wait for
3192 GC collection rather than freeing memory immediately when the refcnt drops

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003651- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3652 start byte and the continuation byte(s) are now considered invalid, instead
3653 of the number of bytes specified by the start byte.
3654 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3655 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3656 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3666 objects. (1) The comparison could incorrectly return True in some cases
3667 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3668 (2) The comparison raised an OverflowError for large integers, leading

3810 non-float non-integer argument is now converted to an integer (if possible)
3811 using its __int__ method. Previously, only small arguments were treated this
3812 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00003863- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3864 operation raises multiple signals and more than one of those signals is
3865 trapped, the specification determines the order in which the signals should be
3866 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00004011- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004012 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4013 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4014 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4034Core and Builtins
4035-----------------
4036
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004037- Issue #7301: Add environment variable $PYTHONWARNINGS.
4038
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004039- Issue #8329: Don't return the same lists from select.select when no fds are
4040 changed.
4041
Georg Brandlfee0f442010-05-22 21:26:21 +00004042- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004043 on 64-bit machines. The shift count for either left or right shift is
4044 permitted to be up to sys.maxsize.
4045
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004046- Ensure that tokenization of identifiers is not affected by locale.
4047
Georg Brandlfee0f442010-05-22 21:26:21 +00004048- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004049
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004050- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4051
Georg Brandlfee0f442010-05-22 21:26:21 +00004052- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4053 with a non-empty format string. This is an effort to future-proof user
4054 code. If a derived class does not currently implement __format__ but later
4055 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004056 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004057 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004058
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004059- Issue #8268: Old-style classes (not just instances) now support weak
4060 references.
4061
Georg Brandlfee0f442010-05-22 21:26:21 +00004062- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4063 is set.

Benjamin Peterson96545892010-03-21 20:21:00 +00004067- Issue #6474: Make error message from passing an inadequate number of keyword
4068 arguments to a function correct.
4069
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004070- Issue #8164: Don't allow lambda functions to have a docstring.
4071
Victor Stinner66644262010-03-10 22:30:19 +00004072- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004073 (SIGINT). If an error occurs while importing the site module, the error is
4074 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004075 module.

Antoine Pitrouf9de5342010-04-05 21:35:07 +00004084- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004085 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4086 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00004088- Issue #8310: Allow dis to examine new style classes.
4089
Georg Brandlfee0f442010-05-22 21:26:21 +00004090- Issue #8257: The Decimal construct now accepts a float instance directly,
4091 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004092
4093 >>> Decimal(1.1)
4094 Decimal('1.100000000000000088817841970012523233890533447265625')
4095
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004096- collections.Counter() now supports a subtract() method.
4097
Georg Brandlfee0f442010-05-22 21:26:21 +00004098- The functools module now has a total_ordering() class decorator to simplify
4099 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004100
Georg Brandlfee0f442010-05-22 21:26:21 +00004101- The functools module also adds cmp_to_key() as a tool to transition old-style
4102 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004103
Georg Brandlfee0f442010-05-22 21:26:21 +00004104- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4105 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004106
Georg Brandlfee0f442010-05-22 21:26:21 +00004107- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4108 InvalidOperation instead of returning False. (Comparisons involving a quiet
4109 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4110 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004111
Georg Brandlfee0f442010-05-22 21:26:21 +00004112- Issue #2531: Comparison operations between floats and Decimal instances now
4113 return a result based on the numeric values of the operands; previously they
4114 returned an arbitrary result based on the relative ordering of id(float) and
4115 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004116
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004117- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004118 argument `-` which tells it to read files to compile from stdin. Each line is
4119 read on demand and the named file is compiled immediately. (Original patch by
4120 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004121
Georg Brandlfee0f442010-05-22 21:26:21 +00004122- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4123 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00004125- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4126 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004127 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004128
Georg Brandlfee0f442010-05-22 21:26:21 +00004129- Comparisons using one of <, <=, >, >= between a complex instance and a
4130 Fractions instance now raise TypeError instead of returning True/False. This
4131 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4132 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004133
Michael Foorde6410c52010-03-29 20:04:23 +00004134- Addition of ``WeakSet`` to the ``weakref`` module.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004143- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004144 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4145 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004146
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004147- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4148 deprecated.
4149
Georg Brandlfee0f442010-05-22 21:26:21 +00004150- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004187- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004188 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4189 log file to compute the next rollover time. If the log file does not exist,
4190 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004191

Georg Brandlba83f822010-03-14 09:50:54 +00004200- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4201 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4202 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004231- Issue #8300: When passing a non-integer argument to struct.pack with any
4232 integer format code, struct.pack first attempts to convert the non-integer
4233 using its __index__ method. If that method is non-existent or raises
4234 TypeError it goes on to try the __int__ method, as described below.
4235
Georg Brandlba83f822010-03-14 09:50:54 +00004236- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4237 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4238 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004239 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4240 inconsistent: __int__ was used for some integer codes but not for others, and
4241 the set of integer codes for which it was used differed between native packing

4474 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004475 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004550 file position when calling `truncate()`. It would previously change the file
4551 position to the given argument, which goes against the tradition of

4555 class used to represent files stored inside an archive. The new
4556 implementation is significantly faster and can be wrapped in a
4557 ``io.BufferedReader`` object for more speedups. It also solves an issue
4558 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4571 encoded string for them. This ensures that the upload and register commands
4572 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004649- The ``__complex__()`` method is now looked up on the class of instances to
4650 make it consistent with other special methods.

4654
Mark Dickinson1b34d252010-01-01 17:27:30 +00004655- Issue #5080: A number of functions and methods previously produced a

4657 These functions and methods now raise TypeError instead. The majority of the
4658 effects of this change are in the extension modules, but some core functions
4659 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4660 and many unicode/str methods.

4674 of integers: the result of a/b is now correctly rounded for ints a and b (at
4675 least on IEEE 754 platforms), and in particular does not depend on the
4676 internal representation of a long.

4684
Georg Brandlba83f822010-03-14 09:50:54 +00004685 These executables now work properly with the arch(1) command: ``arch -ppc
4686 python`` will start a universal binary version of python in PPC mode (unlike

4826 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004827

4829 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004830

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004841
Georg Brandlba83f822010-03-14 09:50:54 +00004842- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4843 decimal string that's guaranteed to round back to x under correct rounding
4844 (with round-half-to-even rounding mode). Previously it gave a string based on
4845 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4846 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4847 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004848
Georg Brandlba83f822010-03-14 09:50:54 +00004849- Issue #7117: On almost all platforms: float-to-string and string-to-float
4850 conversions within Python are now correctly rounded. Places these conversions
4851 occur include: str for floats and complex numbers; the float and complex
4852 constructors; old-style and new-style numeric formatting; serialization and
4853 deserialization of floats and complex numbers using marshal, pickle and json;
4854 parsing of float and imaginary literals in Python code; Decimal-to-float
4855 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004856
Georg Brandlba83f822010-03-14 09:50:54 +00004857 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4858 providing correctly-rounded strtod and dtoa C functions. This code is
4859 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4860 the C compiler. There may be a small number of platforms on which correct
4861 operation of this code cannot be guaranteed, so the code is not used: notably,
4862 this applies to platforms where the C double format is not IEEE 754 binary64,
4863 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4864 and Python's configure script is unable to determine how to change the FPU
4865 precision. On these platforms conversions use the platform strtod and dtoa,
4866 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004867
Georg Brandlba83f822010-03-14 09:50:54 +00004868- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4869 uses the correctly-rounded string <-> float conversions described above (when
4870 available), and so produces correctly rounded results that will display nicely
4871 under the float repr. There are two related small changes: (1) round now
4872 accepts any class with an ``__index__()`` method for its second argument (but
4873 no longer accepts floats for the second argument), and (2) an excessively
4874 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4875 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005022- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5023 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5024 but with at least one decimal point and with a default precision
5025 of 12. Previously, the behavior the same but with a default precision of 6.
5026 This more closely matches ``str()``, and reduces surprises when adding
5027 alignment flags to the empty presentation type. This also affects the new
5028 complex.__format__ in the same way.

5225
Georg Brandlba83f822010-03-14 09:50:54 +00005226- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5227 file objects with closefd=False. The file descriptor is still kept open but
5228 the file object behaves like a closed file. The ``FileIO`` object also got a
5229 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005249- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005252- On windows, ``os.chdir()`` given unicode was not working if
5253 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5254 this code path is really executed because I cannot move to such directory on
5255 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005257- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5258 element is temporarily replaced with an equivalent frozenset. But the
5259 eventual KeyError would always report the empty ``frozenset()`` as the missing
5260 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005280- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5281 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5282 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5283 of using the replace error handler in PyUnicode_DecodeUTF8().
5284
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005285- Issue #3739: The unicode-internal encoder now reports the number of characters

5287
Georg Brandlba83f822010-03-14 09:50:54 +00005288- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5290 gives improved memory leak detection when running under Valgrind, while taking
5291 advantage of pymalloc at other times.

6085 file object.

6537 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006538 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6539 the tests if DISPLAY is defined but can't be used.

6547 C and Python implementations in the stdlib can be adjusted to use it over
6548 time.

6660
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006661- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6662 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6663 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6664 ``printf`` function, whereas PyString_FromFormat has an independent
6665 implementation and uses "%zd" on all platforms for size_t values.
6666 This makes a difference on win64, where ``printf`` needs "%Id" to display
6667 64bit values.

6673 object; previously an int would be returned for small values. the __long__
6674 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006684 was correctly parsed but parsing of subsequent arguments failed.
6685
Vinay Sajip35e3b032008-09-01 14:33:59 +00006686- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006687 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6688 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6690 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6691 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006830What's New in Python 2.6 beta 3?
6831================================
6832
Barry Warsaw07a4a382008-08-21 01:15:08 +00006833*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006834
6835Core and Builtins
6836-----------------
6837
Guido van Rossumf8402962008-08-20 15:01:50 +00006838- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6839 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6840 extensions do not automatically benefit from the class attribute
6841 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6842 to their tp_flags field if they care. This is a backwards
6843 compatibility feature; in 3.0, all types will use the cache by
6844 default.
6845
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006846- Keyword arguments can now follow starred arguments. (``f(a, *args,
6847 keyword=23)`` is now valid syntax.)
6848
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006849- ctypes function pointers that are COM methods have a boolean True
6850 value again.
6851
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006852- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6853 by denying s# to parse objects that have a releasebuffer procedure,
6854 and introducing s*.
6855
Georg Brandl1e13ea92008-08-11 09:07:59 +00006856- Issue #3537: Fix an assertion failure when an empty but presized dict
6857 object was stored in the freelist.
6858
Mark Dickinsonb6467572008-08-04 21:30:09 +00006859- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6860 ValueError consistently across platforms.
6861
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006862- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6863 (64bit Unix, for example), unichr() would truncate its argument and return
6864 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6865
Neal Norwitze7d8be82008-07-31 17:17:14 +00006866- Apply security patches from Apple.
6867
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006868- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6869 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6870
Antoine Pitrou92f82162008-07-25 22:22:08 +00006871- Issue #1819: function calls with several named parameters are now on
6872 average 35% faster (as measured by pybench).
6873
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006874- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6875 the python debugger steps into a class statement: the free variables (local
6876 variables defined in an outer scope) would be deleted from the outer scope.
6877
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006878- Issue #2620: Overflow checking when allocating or reallocating memory
6879 was not always being done properly in some python types and extension
6880 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6881 all been updated to perform better checks and places in the code that
6882 would previously leak memory on the error path when such an allocation
6883 failed have been fixed.
6884
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006885Library
6886-------
6887
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006888- Issue #3612: Added some missing basic types in ctypes.wintypes.
6889
Benjamin Petersone977ad42008-08-20 01:42:01 +00006890- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6891 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6892
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006893- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6894 version reported by these tools does not necessarily follow the python
6895 version numbering scheme, so the module is less strict when parsing it.
6896
Nick Coghlanf70385a2008-08-18 12:42:46 +00006897- Issue #2235: Added Py3k warnings for types which will become unhashable
6898 under the stricter __hash__ inheritance rules in 3.0. Several types
6899 which did not meet the rules for hash invariants and were already
6900 unhashable in 3.0 have now been explicitly flagged as unhashable in
6901 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6902 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6903
Brett Cannon88f801d2008-08-18 00:46:22 +00006904- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6905 imported into the module but exposed as part of the module's API.
6906
Brett Cannon7b96f072008-08-18 00:41:11 +00006907- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6908
Brett Cannon46225e72008-08-18 00:36:52 +00006909- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6910
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006911- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6912
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006913- Issue #3575: Incremental decoder's decode function now takes bytearray
6914 by using 's*' instead of 't#'.
6915
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006916- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006917 fails unicode conversion on 2nd parameter. (windows only)
6918
Georg Brandl222e2082010-08-01 22:27:39 +00006919- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006920 in a redirect.
6921
Brett Cannonabe423e2008-08-16 21:47:07 +00006922- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006923 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006924
Facundo Batistaeb90b782008-08-16 14:44:07 +00006925- Issue #2776: fixed small issue when handling an URL with double slash
6926 after a 302 response in the case of not going through a proxy.
6927
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006928- Issue #2676: in the email package, content-type parsing was hanging on
6929 pathological input because of quadratic or exponential behaviour of a
6930 regular expression.
6931
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006932- Issue #3476: binary buffered reading through the new "io" library is now
6933 thread-safe.
6934
Brett Cannonbf3157b2008-08-14 05:00:03 +00006935- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6936 since mimetools itself is deprecated. Because modules are cached, all
6937 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6938
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006939- Issue #3134: shutil referenced undefined WindowsError symbol.
6940
Robert Schuppenies14646332008-08-10 11:01:53 +00006941- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6942 menu entries were not deleted.
6943
Brett Cannon83e81842008-08-09 23:30:55 +00006944- Copied the implementation of reduce() to _functools.reduce() to have a
6945 version that did not raise a DeprecationWarning under -3.
6946
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006947- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6948 a MemoryError rather than silently stop the iteration.
6949
Guido van Rossum59ce9012008-08-09 14:55:34 +00006950- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6951 to _sre.compile() will now be rejected. This should not affect anybody
6952 since the re.compile() function never generates invalid re-bytecode.
6953
Skip Montanaroa032bf42008-08-08 22:52:51 +00006954- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6955 upon first access it can be automatically initialized from the csv file if
6956 it wasn't initialized during instantiation.
6957
Brett Cannon3aa2a492008-08-06 22:28:09 +00006958- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6959 the reload() built-in has been removed.
6960
Brett Cannon7e30b672008-08-04 21:52:25 +00006961- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006962 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006963 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6964 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6965 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6966 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6967 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006968
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006969- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6970 raised an AttributeError.
6971
Benjamin Peterson01a24322008-07-28 23:35:27 +00006972- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006973 asking for a specific length. This problem only affected files opened
6974 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006975
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006976- Issue #3449: Update decimal module to use most recent specification
6977 (v. 1.68) and tests (v. 2.58) from IBM.
6978
Georg Brandl222e2082010-08-01 22:27:39 +00006979- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006980

Raymond Hettinger8c664e82008-07-25 18:43:33 +00006982 on a closed shelf.
6983
Georg Brandlf9efabb2008-07-23 15:16:45 +00006984- Deprecate the "ast" parser function aliases.
6985
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006986- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6987
6988- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6989 invalid arguments.
6990
6991- Issue #3302: Fix several crashes when calling locale's gettext functions
6992 with None arguments.
6993
6994- Issue #3389: Allow resolving dotted names for handlers in logging
6995 configuration files.
6996
6997- Deprecate the sunaudio module for removal in Python 3.0.
6998
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006999- Issue #3394: zipfile.writestr sets external attributes when passed a
7000 file name rather than a ZipInfo instance, so files are extracted with
7001 mode 0600 rather than 000 under Unix.
7002
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007003- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7004 argument in python 2.5, this broke code that subclassed Popen to include its
7005 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7013-------------
7014
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007015- Issue #2235: the C API function PyObject_HashNotImplemented and its
7016 interaction with the tp_hash slot (added in 2.6b2) are now documented
7017
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007018- Issue #643841: The language reference now provides more detailed
7019 coverage of the lookup process for special methods. The disclaimers
7020 regarding lack of coverage of new-style classes have also been
7021 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007024What's New in Python 2.6 beta 2?
7025================================
7026
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007027*Release date: 17-Jul-2008*
7028
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007029Core and Builtins
7030-----------------
7031
Georg Brandl3e483f62008-07-16 22:57:41 +00007032- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7033 its methods now allow for items objects that can be converted to
7034 an integer using operator.index().
7035
Mark Dickinson64b7e502008-07-16 09:40:03 +00007036- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7037 produced a ValueError instead of giving the correct float.
7038
Eric Smitha5fa5a22008-07-16 00:11:49 +00007039- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7040 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7041
Mark Dickinson7103aa42008-07-15 19:08:33 +00007042- Issue #3008: the float type has a new instance method 'float.hex'
7043 and a new class method 'float.fromhex' to convert floating-point
7044 numbers to and from hexadecimal strings, respectively.
7045
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007046- Issue #2235: __hash__ is once again inherited by default. To allow
7047 collections.Hashable to remain meaningful in the presence of the
7048 default hash implementation (object.__hash__), it is now possible
7049 to explicit block inheritance of hash by setting __hash__=None at
7050 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7051 level.
7052
Nick Coghlanb028f502008-07-13 14:52:36 +00007053- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7054 the parent module cannot be found while performing an absolute import.
7055 This means that an incorrectly defined __package__ attribute will
7056 now only prevent relative imports in that module rather than causing
7057 all imports from that module to fail.
7058
Nick Coghlan14ff9942008-07-08 14:21:42 +00007059- Issue #2517: Allow unicode messages in Exceptions again by correctly
7060 bypassing the instance dictionary when looking up __unicode__ on
7061 new-style classes.
7062
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007063- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7064 set to a custom object whose write() method happens to install
7065 another file in sys.stdout.
7066
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007067- Issue #3088: Corrected a race condition in classes derived from
7068 threading.local: the first member set by a thread could be saved in
7069 another thread's dictionary.
7070
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007071- Issue #3004: Minor change to slice.indices(): the start and stop
7072 arguments are now treated identically, making the behaviour easier
7073 to describe and understand. For example, slice(None, -10,
7074 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7075 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7076 10, -1).
7077
Georg Brandl278fc502008-07-19 12:46:12 +00007078- Issue #3219: Calling a function with repeated keyword arguments,
7079 f(a=2, a=23), would not cause a syntax error. This was a regression
7080 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007081
Georg Brandl278fc502008-07-19 12:46:12 +00007082- Issue #2862: Make int and float freelist management consistent with
7083 other freelists. Changes their CompactFreeList apis into
7084 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00007089- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7090 api functions without holding the GIL, which could lead to a fatal
7091 error when they failed.
7092
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007093- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7107 a valid dlerror() message.
7108
Thomas Heller2bad6572008-07-15 17:19:50 +00007109- Issue #3258: Fixed a crash when a ctypes POINTER type to an

7525
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007526- On MacOS X it is now possible to install the framework in 64-bit
7527 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007528 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007529
7530 This is controlled by the configure argument ``--with-universal-archs``:
7531
7532 - ``--with-universal-archs=all``: install 4-way universal
7533
7534 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7535
7536 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7537
7538 This option should be used in combination with ``--enable-universalsdk=``.
7539
7540 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7576 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007577
Christian Heimese74c8f22008-04-19 02:23:57 +00007578- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7579
Georg Brandl3ee81df2008-05-17 18:14:43 +00007580- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
7581 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007582

Georg Brandl3ee81df2008-05-17 18:14:43 +00007589- Issue #1631171: Re-implement the 'warnings' module in C (the
7590 original Python code has been kept as backup). This will allow for
7591 using the 'warning's machinery in such places as the parser where
7592 use of pure Python code is not possible. Both the ``showarning()``
7593 and ``formatwarning()`` gain an optional 'line' argument which is
7594 not called by default for backwards-compatibility reasons. Setting
7595 ``warnings.showwarning()`` to an implementation that lacks support
7596 for the ``line`` argument will raise a DeprecationWarning.

7620
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007621- The getpass module has been improved on Unix. It now uses /dev/tty
7622 by default and uses stderr instead of stdout. A GetPassWarning is
7623 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007624

Georg Brandl3ee81df2008-05-17 18:14:43 +00007638- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007639 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007659- Issue #2550: The approach used by client/server code for obtaining
7660 ports to listen on in network-oriented tests has been refined in an
7661 effort to facilitate running multiple instances of the entire
7662 regression test suite in parallel without issue.
7663 test_support.bind_port() has been fixed such that it will always
7664 return a unique port -- which wasn't always the case with the
7665 previous implementation, especially if socket options had been set
7666 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7667 new implementation of bind_port() will actually raise an exception
7668 if it is passed an AF_INET/SOCK_STREAM socket with either the
7669 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7670 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7671 the socket it's been passed. This currently only applies to
7672 Windows. This option prevents any other sockets from binding to the
7673 host/port we've bound to, thus removing the possibility of the
7674 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7675 when a second SOCK_STREAM socket binds and accepts to a host/port
7676 that's already been bound by another socket. The optional preferred
7677 port parameter to bind_port() has been removed. Under no
7678 circumstances should tests be hard coding ports!
7679
7680 test_support.find_unused_port() has also been introduced, which will
7681 pass a temporary socket object to bind_port() in order to obtain an
7682 unused port. The temporary socket object is then closed and
7683 deleted, and the port is returned. This method should only be used
7684 for obtaining an unused port in order to pass to an external program
7685 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7686 a parameter to a server-oriented class that doesn't give you direct
7687 access to the underlying socket used.
7688
7689 Finally, test_support.HOST has been introduced, which should be used
7690 for the host argument of any relevant socket calls (i.e. bind and
7691 connect).

7693 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007694 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

7696 test_asynchat and test_socket_ssl.
7697
Georg Brandl3ee81df2008-05-17 18:14:43 +00007698 It is now possible for multiple instances of the regression test
7699 suite to run in parallel without issue.

7967
Fred Drakea8ee94b2008-03-01 02:45:07 +00007968- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007969 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007970
Georg Brandlad61bc82008-02-23 15:11:18 +00007971- Issue #2067: file.__exit__() now calls subclasses' close() method.
7972
7973- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007974
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007975- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007976 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007977
Eric Smitha73fbe72008-02-23 03:09:44 +00007978- Added the future_builtins module, which contains hex() and oct().
7979 These are the PEP 3127 version of these functions, designed to be
7980 compatible with the hex() and oct() builtins from Python 3.0. They
7981 differ slightly in their output formats from the existing, unchanged
7982 Python 2.6 builtins. The expected usage of the future_builtins
7983 module is:
7984 from future_builtins import hex, oct
7985
Eric Smith7ef40bf2008-02-20 23:34:22 +00007986- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7987 exponents for exponents with absolute value < 100. Follows C99
7988 standard. This is a change on Windows, which would use 3 digits.
7989 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7990 so that any alterations it does to the resulting string will be
7991 available in stringlib/formatter.h (for float.__format__).
7992
Eric Smith5a3c1352008-02-19 13:21:56 +00007993- Implemented PEP 3101, Advanced String Formatting. This adds a new
7994 builtin format(); a format() method for str and unicode; a
7995 __format__() method to object, str, unicode, int, long, float, and
7996 datetime; the class string.Formatter; and the C API
7997 PyObject_Format().
7998
Georg Brandl3ee81df2008-05-17 18:14:43 +00007999- Fixed several potential crashes, all caused by specially crafted
8000 __del__ methods exploiting objects in temporarily inconsistent
8001 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008002
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008003- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008004 prevent a possible crash: an Abstract Base Class would try to access
8005 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008006
Georg Brandl3ee81df2008-05-17 18:14:43 +00008007- Fixed repr() and str() of complex numbers with infinity or nan as
8008 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008009
Georg Brandl3ee81df2008-05-17 18:14:43 +00008010- Clear all free lists during a gc.collect() of the highest generation
8011 in order to allow pymalloc to free more arenas. Python may give back
8012 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008013
Georg Brandl3ee81df2008-05-17 18:14:43 +00008014- Issue #2045: Fix an infinite recursion triggered when printing a
8015 subclass of collections.defaultdict, if its default_factory is set
8016 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008017
Christian Heimesf75dbef2008-02-08 00:11:31 +00008018- Fixed a minor memory leak in dictobject.c. The content of the free
8019 list was not freed on interpreter shutdown.
8020
Georg Brandl21e99f42010-03-07 15:23:59 +00008021- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008022 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008023
Georg Brandl3ee81df2008-05-17 18:14:43 +00008024- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8025 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008026 to compact the internal free lists of pre-allocted ints and floats.
8027
Georg Brandl3ee81df2008-05-17 18:14:43 +00008028- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8029 calls. Python expected the return type int but the fork familie
8030 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008031
Georg Brandl3ee81df2008-05-17 18:14:43 +00008032- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8033 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008034
Georg Brandl3ee81df2008-05-17 18:14:43 +00008035- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8036 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008037

8039 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008040
Georg Brandl3ee81df2008-05-17 18:14:43 +00008041- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8042 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008043
Georg Brandl3ee81df2008-05-17 18:14:43 +00008044- Patch #1473257: generator objects gain a gi_code attribute. This is
8045 the same object as the func_code attribute of the function that
8046 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008047
Georg Brandl3ee81df2008-05-17 18:14:43 +00008048- Issue #1920: "while 0" statements were completely removed by the
8049 compiler, even in the presence of an "else" clause, which is
8050 supposed to be run when the condition is false. Now the compiler
8051 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008052
Guido van Rossumeead05f2008-01-24 18:21:02 +00008053- A few crashers fixed: weakref_in_del.py (issue #1377858);
8054 loosing_dict_ref.py (issue #1303614, test67.py);
8055 borrowed_ref_[34].py (not in tracker).
8056
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008057- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008058 suppressed while an extension is loaded by calling SetErrorMode in
8059 dynload_win.c. The error is still reported properly.
8060
Georg Brandl3ee81df2008-05-17 18:14:43 +00008061- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008062 several extension methods and modules do not work without unicode
8063 support.
8064
Georg Brandl26543b12008-01-21 18:36:51 +00008065- Issue #1882: when compiling code from a string, encoding cookies in the
8066 second line of code were not always recognized correctly.
8067
Georg Brandl14404b62008-01-19 19:27:05 +00008068- Issue #1679: "0x" was taken as a valid integer literal.
8069
Georg Brandl6caad7d2008-01-26 14:19:22 +00008070- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008071 added.
8072
Christian Heimesc94e2b52008-01-14 04:13:37 +00008073- sys.float_info / PyFloat_GetInfo: The floating point information
8074 object was converted from a dict to a specialized structseq object.
8075
Georg Brandl3ee81df2008-05-17 18:14:43 +00008076- Patch #1816: Added sys.flags structseq. It exposes the status of
8077 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008078
Georg Brandl3ee81df2008-05-17 18:14:43 +00008079- Objects/structseq.c: Implemented new structseq representation. The
8080 patch makes structseqs (e.g. the return value of os.stat) more
8081 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008082
Georg Brandl3ee81df2008-05-17 18:14:43 +00008083- Patch #1700288: added a type attribute cache that caches method
8084 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008085
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008086- Bug #1776: __import__() no longer accepts filenames on any platform.
8087 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008088

8090
Georg Brandl3ee81df2008-05-17 18:14:43 +00008091- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8092 envvar and sys.dont_write_bytecode attribute. All these can be set
8093 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008094
Georg Brandl3ee81df2008-05-17 18:14:43 +00008095- Improve some exception messages when Windows fails to load an
8096 extension module. Now we get for example '%1 is not a valid Win32
8097 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008098
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099- Bug #1481296: Fixed long(float('nan')) != 0L.

8102 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008103
Christian Heimes0a8143f2007-12-18 23:22:54 +00008104- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008105 and INF. float("nan"), float("inf") and float("-inf") now work on
8106 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008107
Georg Brandl3ee81df2008-05-17 18:14:43 +00008108- Compiler now generates simpler and faster code for dictionary
8109 literals. The oparg for BUILD_MAP now indicates an estimated
8110 dictionary size. There is a new opcode, STORE_MAP, for adding
8111 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008145- Issue #1265: Fix a problem with sys.settrace, if the tracing
8146 function uses a generator expression when at the same time the
8147 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008148
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008149- sets and frozensets now have an isdisjoint() method.

Georg Brandl21e99f42010-03-07 15:23:59 +00008155- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008156 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8157 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008158
Georg Brandl3ee81df2008-05-17 18:14:43 +00008159- Issue #1686386: Tuple's tp_repr did not take into account the
8160 possibility of having a self-referential tuple, which is possible
8161 from C code. Nor did object's tp_str consider that a type's tp_str
8162 could do something that could lead to an inifinite recursion.
8163 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8164 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008165
Georg Brandl3ee81df2008-05-17 18:14:43 +00008166- Issue #1164: It was possible to trigger deadlock when using the
8167 'print' statement to write to a file since the GIL was not released
8168 as needed. Now PyObject_Print() does the right thing along with
8169 various tp_print implementations of the built-in types and those in
8170 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008172- Issue #1147: Exceptions were directly allowing string exceptions in
8173 their throw() method even though string exceptions no longer
8174 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008176- Issue #1096: Prevent a segfault from getting the repr of a very
8177 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00008179- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008180 PyObject_Call() never calling back out to Python code to trigger
8181 recursion depth updates/checks. Required the creation of a static
8182 RuntimeError instance in case normalizing an exception put the
8183 recursion check value past its limit. Fixes crashers
8184 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008199- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008200 __*__ attributes. (Some already existed, e.g., __doc__ and
8201 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008202
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008203- Add -3 option to the interpreter to warn about features that are
8204 deprecated and will be changed/removed in Python 3.0.
8205
Georg Brandl2134e752007-05-21 20:34:16 +00008206- Patch #1686487: you can now pass any mapping after '**' in function
8207 calls.
8208
Collin Winter62903052007-05-18 23:11:24 +00008209- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008210 "except E as target:". This is to provide forwards compatibility
8211 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008212
Brett Cannon229cee22007-05-05 01:34:02 +00008213- Deprecate BaseException.message as per PEP 352.
8214
Georg Brandl3ee81df2008-05-17 18:14:43 +00008215- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00008218- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008219 setting a plain string, ie don't expand to single letter identifiers.
8220
Raymond Hettinger13936692007-04-11 18:40:58 +00008221- Request #1191699: Slices can now be pickled.
8222
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008223- Request #1193128: str.translate() now allows a None argument for
8224 translations that only remove characters without re-mapping the
8225 remaining characters.
8226
Georg Brandl5cb76c12007-03-21 09:00:39 +00008227- Patch #1682205: a TypeError while unpacking an iterable is no longer

8229
Neal Norwitzaa754b72007-03-21 06:39:48 +00008230- Remove unused file Python/fmod.c.
8231
Guido van Rossum143b5642007-03-23 04:58:42 +00008232- Bug #1683368: The object.__init__() and object.__new__() methods are
8233 now stricter in rejecting excess arguments. The only time when
8234 either allows excess arguments is when it is not overridden and the
8235 other one is. For backwards compatibility, when both are
8236 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008237 warning later). Also, type.__init__() insists on the same signature
8238 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008239
Georg Brandl3ee81df2008-05-17 18:14:43 +00008240- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8241 object to complex using its __complex__() method before falling back
8242 to the __float__() method. Therefore, the functions in the cmath
8243 module now can operate on objects that define a __complex__()
8244 method.

8255 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008262- Bug #1678647: write a newline after printing an exception in any
8263 case, even when converting the value to a string failed.
8264
Georg Brandl871f1bc2007-03-12 13:17:36 +00008265- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008266 its argument, if it exists. If not, it will work like before. This
8267 allows customizing the output of dir() in the presence of a
8268 __getattr__().

8277 parthensized forms. This means complex(repr(x)) now works instead of
8278 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008279
Georg Brandlaa2321b2007-03-07 00:40:28 +00008280- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008281 makes the filenames the warning module prints much more sensible
8282 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008283

Georg Brandl0fca97a2007-03-05 22:28:08 +00008295- Patch #1674228: when assigning a slice (old-style), check for the
8296 sq_ass_slice instead of the sq_slice slot.
8297
Georg Brandl3ee81df2008-05-17 18:14:43 +00008298- When printing an unraisable error, don't print exceptions. before

8908 Python would crash instead of raising an error.
8909
Thomas Hellerc2f77252007-03-09 19:21:28 +00008910- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
8911 returned string up to the first NUL character.

8925 accepted in TestSuite.addTest(). This should cause no
8926 incompatibility since it never made sense with ordinary subclasses
8927 -- the failure just occurred later, with a more cumbersome
8928 exception.

9206 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009207
Georg Brandl3ee81df2008-05-17 18:14:43 +00009208- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009209 that the SMTP.starttls() caller no longer needs to call ehlo()
9210 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009211 does not claim to support starttls. Adds the
9212 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00009311 time so that opening a database previously created with the DB_DUP
9312 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9313 opens. Specifically: dictionary assignment to a DB object will
9314 replace all values for a given key when the database allows
9315 duplicate values. DB users should use DB.put(k, v) when they want
9316 to store duplicates; not DB[k] = v.

9323 characters with ASCII value less than 32. Also, it correctly quotes
9324 dots only if they occur on a single line, as opposed to the previous
9325 behavior of quoting dots if they are the second character of any
9326 line.

Neal Norwitz92422fb2006-08-18 03:57:54 +00009653C API
9654-----
9655
Georg Brandl3ee81df2008-05-17 18:14:43 +00009656- Unified naming convention for free lists and their limits. All free
9657 lists in Object/ are named ``free_list``, the counter ``numfree``
9658 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9659 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009660
Georg Brandl3ee81df2008-05-17 18:14:43 +00009661- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9662 to ``PyTuple_SetItem``, it can be used to populate a brand new
9663 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009664
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009665- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009667- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9668 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9669 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009670
9671- Patch #1720595: add T_BOOL to the range of structmember types.
9672
9673- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9674 ``PyFloat_GetInfo()`` to the float API.
9675
Georg Brandl3ee81df2008-05-17 18:14:43 +00009676- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9677 of w# format code incorrectly truncated the length to an int, even
9678 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9679 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009680
Georg Brandl3ee81df2008-05-17 18:14:43 +00009681- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9682 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009684- PEP 3123: Provide forward compatibility with Python 3.0, while
9685 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9686 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009687
Georg Brandl3ee81df2008-05-17 18:14:43 +00009688- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9689 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009690
9691- Patch #1733960: Allow T_LONGLONG to accept ints.
9692
9693- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9694

9698
9699- Fix some leftovers from the conversion from int to Py_ssize_t
9700 (relevant to strings and sequences of more than 2**31 items).
9701
9702- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9703 outside of pystate.c and should not be necessary.
9704
Georg Brandl3ee81df2008-05-17 18:14:43 +00009705- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9706 absolute imports. In earlier versions they might have used relative
9707 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009708
Georg Brandl3ee81df2008-05-17 18:14:43 +00009709- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9710 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009711
Georg Brandl3ee81df2008-05-17 18:14:43 +00009712- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009718- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9719 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9720 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9721 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009722
Georg Brandl3ee81df2008-05-17 18:14:43 +00009723- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00009735- Removed the macfs module. It had been deprecated since Python 2.5.
9736 This lead to the deprecation of macostools.touched() as it relied
9737 solely on macfs and was a no-op under OS X.
