Ned Deily18fae3f2013-01-31 01:24:55 -08001457- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1458 In particular, fix extension module build failures when trying to use
1459 32-bit-only installer Pythons on systems with Xcode 4 (currently
1460 OS X 10.8, 10.7, and optionally 10.6).
1461 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1462 * Since Xcode 4 removes ppc support, extension module builds now
1463 check for ppc compiler support and by default remove ppc and
1464 ppc64 archs when they are not available.
1465 * Extension module builds now revert to using system installed
1466 headers and libs (/usr and /System/Library) if the SDK used
1467 to build the interpreter is not installed or has moved.
1468 * Try to avoid building extension modules with deprecated
1469 and problematic Apple llvm-gcc compiler. If original compiler
1470 is not available, use clang instead by default.

1820
Mark Dickinsondbbed042011-09-19 16:38:08 +01001821- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1822 int.__pow__. These overflow checks were causing int.__pow__ to produce
1823 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001824 compiler optimizing the check away. Also fix similar overflow checks
1825 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1826 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02001837- Issue #12149: Update the method cache after a type's dictionnary gets
1838 cleared by the garbage collector. This fixes a segfault when an instance
1839 and its type get caught in a reference cycle, and the instance's
1840 deallocator calls one of the methods on the type (e.g. when subclassing
1841 IOBase). Diagnosis and patch by Davide Rizzo.
1842
Florent Xiclunaa1f948b2012-01-24 21:05:10 +01001843- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02001850 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
1851 raw_input() interrupted by CTRL+c.
1852
Łukasz Langa7a153902011-10-18 17:16:00 +02001853- Issue #10860: httplib now correctly handles an empty port after port
1854 delimiter in URLs.
1855

Florent Xiclunac2279652012-02-12 14:49:03 +01001894- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001895 has left two versions of customize_compiler, the original in
1896 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001901- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1902 Distutils-based packages with C extension modules may fail because
1903 Apple has removed gcc-4.2, the version used to build python.org
1904 64-bit/32-bit Pythons. If the user does not explicitly override
1905 the default C compiler by setting the CC environment variable,
1906 Distutils will now attempt to compile extension modules with clang
1907 if gcc-4.2 is required but not found. Also as a convenience, if
1908 the user does explicitly set CC, substitute its value as the default
1909 compiler in the Distutils LDSHARED configuration variable for OS X.
1910 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1911 SDK, neither of which are available in Xcode 4. This change does not
1912 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002162- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2163 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2164 interpreter process. This could cause failures in non-Distutils subprocesses
2165 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002166 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002167 deployment target only in the environment of each build subprocess. It is
2168 still possible to globally override the default by setting
2169 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2170 greater or equal to the default value, the value with which the interpreter
2171 was built.

2200 updating the check interval, so if the user decreases the check interval,
2201 the ticker doesn't have to wind down to zero from the old starting point
2202 before the new interval takes effect. And if the user increases the
2203 interval, it makes sure the new limit takes effect right away rather have an
2204 early task switch before recognizing the new interval.

3185 This prevents user-created self-referencing ordered dictionaries from
3186 becoming permanently uncollectable GC garbage. The downside is that
3187 removing __del__ means that the internal doubly-linked list has to wait for
3188 GC collection rather than freeing memory immediately when the refcnt drops
3189 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003647- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3648 start byte and the continuation byte(s) are now considered invalid, instead
3649 of the number of bytes specified by the start byte.
3650 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3651 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3652 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3653 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003661- Issue #8748: Fix two issues with comparisons between complex and integer
3662 objects. (1) The comparison could incorrectly return True in some cases
3663 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3664 (2) The comparison raised an OverflowError for large integers, leading
3665 to unpredictable exceptions when combining integers and complex objects
3666 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003668- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00003805- Issue #1533: Fix inconsistency in range function argument processing: any
3806 non-float non-integer argument is now converted to an integer (if possible)
3807 using its __int__ method. Previously, only small arguments were treated this
3808 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00003859- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3860 operation raises multiple signals and more than one of those signals is
3861 trapped, the specification determines the order in which the signals should be
3862 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00004007- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004008 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4009 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4010 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

Benjamin Petersonfbac6c12010-04-10 16:22:05 +00004028*Release date: 2010-04-10*
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +00004029
4030Core and Builtins
4031-----------------
4032
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004033- Issue #7301: Add environment variable $PYTHONWARNINGS.
4034
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004035- Issue #8329: Don't return the same lists from select.select when no fds are
4036 changed.
4037
Georg Brandlfee0f442010-05-22 21:26:21 +00004038- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004039 on 64-bit machines. The shift count for either left or right shift is
4040 permitted to be up to sys.maxsize.
4041
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004042- Ensure that tokenization of identifiers is not affected by locale.
4043
Georg Brandlfee0f442010-05-22 21:26:21 +00004044- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004045
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004046- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4047
Georg Brandlfee0f442010-05-22 21:26:21 +00004048- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4049 with a non-empty format string. This is an effort to future-proof user
4050 code. If a derived class does not currently implement __format__ but later
4051 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004052 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004053 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004054
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004055- Issue #8268: Old-style classes (not just instances) now support weak
4056 references.
4057
Georg Brandlfee0f442010-05-22 21:26:21 +00004058- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4059 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004060
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004061- Issue #1583863: An unicode subclass can now override the __unicode__ method

4064 arguments to a function correct.
4065
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004066- Issue #8164: Don't allow lambda functions to have a docstring.
4067
Victor Stinner66644262010-03-10 22:30:19 +00004068- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004069 (SIGINT). If an error occurs while importing the site module, the error is
4070 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004071 module.

R. David Murray661303f2010-04-13 20:57:40 +00004078- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
4079
Antoine Pitrouf9de5342010-04-05 21:35:07 +00004080- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00004081 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
4082 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00004084- Issue #8310: Allow dis to examine new style classes.
4085
Georg Brandlfee0f442010-05-22 21:26:21 +00004086- Issue #8257: The Decimal construct now accepts a float instance directly,
4087 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004088
4089 >>> Decimal(1.1)
4090 Decimal('1.100000000000000088817841970012523233890533447265625')
4091
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004092- collections.Counter() now supports a subtract() method.
4093
Georg Brandlfee0f442010-05-22 21:26:21 +00004094- The functools module now has a total_ordering() class decorator to simplify
4095 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00004096
Georg Brandlfee0f442010-05-22 21:26:21 +00004097- The functools module also adds cmp_to_key() as a tool to transition old-style
4098 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00004099
Georg Brandlfee0f442010-05-22 21:26:21 +00004100- Issue #8294: The Fraction constructor now accepts Decimal and float instances
4101 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00004102
Georg Brandlfee0f442010-05-22 21:26:21 +00004103- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4104 InvalidOperation instead of returning False. (Comparisons involving a quiet
4105 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4106 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004107
Georg Brandlfee0f442010-05-22 21:26:21 +00004108- Issue #2531: Comparison operations between floats and Decimal instances now
4109 return a result based on the numeric values of the operands; previously they
4110 returned an arbitrary result based on the relative ordering of id(float) and
4111 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004112
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004113- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004114 argument `-` which tells it to read files to compile from stdin. Each line is
4115 read on demand and the named file is compiled immediately. (Original patch by
4116 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004117
Georg Brandlfee0f442010-05-22 21:26:21 +00004118- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
4119 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00004121- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4122 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004123 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004124
Georg Brandlfee0f442010-05-22 21:26:21 +00004125- Comparisons using one of <, <=, >, >= between a complex instance and a
4126 Fractions instance now raise TypeError instead of returning True/False. This
4127 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4128 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00004129
Michael Foorde6410c52010-03-29 20:04:23 +00004130- Addition of ``WeakSet`` to the ``weakref`` module.

4138
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004139- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00004140 didn't support chflags() (for example ZFS under FreeBSD). The error is now
4141 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00004142
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00004143- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
4144 deprecated.
4145
Georg Brandlfee0f442010-05-22 21:26:21 +00004146- Issue #7860: platform.uname now reports the correct 'machine' type when Python
4147 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00004148

4153 existing at the same time, causing a Unicode error when configuration code
4154 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00004155
Georg Brandlfee0f442010-05-22 21:26:21 +00004156- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
4157 when logging occurs.

4160 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
4161 reads and writes are always retried by OpenSSL itself.

4169 memoryviews.
Antoine Pitroud7b731d2010-03-17 22:45:39 +00004170
Matthias Klose8b411682010-03-16 10:48:52 +00004171- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox

Vinay Sajipecfa08f2010-03-12 09:16:10 +00004183- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00004184 for ``TimedRotatingFileHandler`` by using the modification time of an existing
4185 log file to compute the next rollover time. If the log file does not exist,
4186 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00004187
Georg Brandlba83f822010-03-14 09:50:54 +00004188- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00004196- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4197 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4198 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004227- Issue #8300: When passing a non-integer argument to struct.pack with any
4228 integer format code, struct.pack first attempts to convert the non-integer

4230 TypeError it goes on to try the __int__ method, as described below.
4231
Georg Brandlba83f822010-03-14 09:50:54 +00004232- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4233 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4234 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004235 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4236 inconsistent: __int__ was used for some integer codes but not for others, and
4237 the set of integer codes for which it was used differed between native packing
4238 and standard packing.)

4653 These functions and methods now raise TypeError instead. The majority of the

4655 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4656 and many unicode/str methods.

4672 internal representation of a long.

4822 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004823
Georg Brandlba83f822010-03-14 09:50:54 +00004824- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4825 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004826
Georg Brandlba83f822010-03-14 09:50:54 +00004827- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4828 1e-100 used to raise OverflowError, but now gives the requested 120
4829 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004837
Georg Brandlba83f822010-03-14 09:50:54 +00004838- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4839 decimal string that's guaranteed to round back to x under correct rounding
4840 (with round-half-to-even rounding mode). Previously it gave a string based on
4841 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4842 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4843 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004844
Georg Brandlba83f822010-03-14 09:50:54 +00004845- Issue #7117: On almost all platforms: float-to-string and string-to-float
4846 conversions within Python are now correctly rounded. Places these conversions
4847 occur include: str for floats and complex numbers; the float and complex
4848 constructors; old-style and new-style numeric formatting; serialization and
4849 deserialization of floats and complex numbers using marshal, pickle and json;
4850 parsing of float and imaginary literals in Python code; Decimal-to-float
4851 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004852
Georg Brandlba83f822010-03-14 09:50:54 +00004853 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4854 providing correctly-rounded strtod and dtoa C functions. This code is
4855 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4856 the C compiler. There may be a small number of platforms on which correct
4857 operation of this code cannot be guaranteed, so the code is not used: notably,
4858 this applies to platforms where the C double format is not IEEE 754 binary64,
4859 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4860 and Python's configure script is unable to determine how to change the FPU
4861 precision. On these platforms conversions use the platform strtod and dtoa,
4862 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004863
Georg Brandlba83f822010-03-14 09:50:54 +00004864- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4865 uses the correctly-rounded string <-> float conversions described above (when
4866 available), and so produces correctly rounded results that will display nicely
4867 under the float repr. There are two related small changes: (1) round now
4868 accepts any class with an ``__index__()`` method for its second argument (but
4869 no longer accepts floats for the second argument), and (2) an excessively
4870 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4871 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005018- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5019 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5020 but with at least one decimal point and with a default precision
5021 of 12. Previously, the behavior the same but with a default precision of 6.
5022 This more closely matches ``str()``, and reduces surprises when adding
5023 alignment flags to the empty presentation type. This also affects the new
5024 complex.__format__ in the same way.

5215
Georg Brandlba83f822010-03-14 09:50:54 +00005216- Issue #3689: The list reversed iterator now supports __length_hint__ instead

5221
Georg Brandlba83f822010-03-14 09:50:54 +00005222- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5223 file objects with closefd=False. The file descriptor is still kept open but
5224 the file object behaves like a closed file. The ``FileIO`` object also got a
5225 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005245- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005248- On windows, ``os.chdir()`` given unicode was not working if
5249 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5250 this code path is really executed because I cannot move to such directory on
5251 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005253- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5254 element is temporarily replaced with an equivalent frozenset. But the
5255 eventual KeyError would always report the empty ``frozenset()`` as the missing
5256 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005276- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5277 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5278 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5279 of using the replace error handler in PyUnicode_DecodeUTF8().
5280
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005281- Issue #3739: The unicode-internal encoder now reports the number of characters

5283
Georg Brandlba83f822010-03-14 09:50:54 +00005284- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5285 allocator will be automatically disabled when running under Valgrind. This
5286 gives improved memory leak detection when running under Valgrind, while taking
5287 advantage of pymalloc at other times.

6533 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006534 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6535 the tests if DISPLAY is defined but can't be used.

6542 test_warnings have been adjusted to use it, tests for other modules with both
6543 C and Python implementations in the stdlib can be adjusted to use it over
6544 time.

6656
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006657- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6658 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6659 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6660 ``printf`` function, whereas PyString_FromFormat has an independent
6661 implementation and uses "%zd" on all platforms for size_t values.
6662 This makes a difference on win64, where ``printf`` needs "%Id" to display
6663 64bit values.

6669 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006680 was correctly parsed but parsing of subsequent arguments failed.
6681
Vinay Sajip35e3b032008-09-01 14:33:59 +00006682- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006683 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6684 mechanism. In the process, fix a bug where isinstance() and issubclass(),

6686 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6687 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006826What's New in Python 2.6 beta 3?
6827================================
6828
Barry Warsaw07a4a382008-08-21 01:15:08 +00006829*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006830
6831Core and Builtins
6832-----------------
6833
Guido van Rossumf8402962008-08-20 15:01:50 +00006834- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6835 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6836 extensions do not automatically benefit from the class attribute
6837 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6838 to their tp_flags field if they care. This is a backwards
6839 compatibility feature; in 3.0, all types will use the cache by
6840 default.
6841
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006842- Keyword arguments can now follow starred arguments. (``f(a, *args,
6843 keyword=23)`` is now valid syntax.)
6844
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006845- ctypes function pointers that are COM methods have a boolean True
6846 value again.
6847
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006848- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6849 by denying s# to parse objects that have a releasebuffer procedure,
6850 and introducing s*.
6851
Georg Brandl1e13ea92008-08-11 09:07:59 +00006852- Issue #3537: Fix an assertion failure when an empty but presized dict
6853 object was stored in the freelist.
6854
Mark Dickinsonb6467572008-08-04 21:30:09 +00006855- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6856 ValueError consistently across platforms.
6857
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006858- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6859 (64bit Unix, for example), unichr() would truncate its argument and return
6860 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6861
Neal Norwitze7d8be82008-07-31 17:17:14 +00006862- Apply security patches from Apple.
6863
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006864- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6865 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6866
Antoine Pitrou92f82162008-07-25 22:22:08 +00006867- Issue #1819: function calls with several named parameters are now on
6868 average 35% faster (as measured by pybench).
6869
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006870- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6871 the python debugger steps into a class statement: the free variables (local
6872 variables defined in an outer scope) would be deleted from the outer scope.
6873
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006874- Issue #2620: Overflow checking when allocating or reallocating memory
6875 was not always being done properly in some python types and extension
6876 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6877 all been updated to perform better checks and places in the code that
6878 would previously leak memory on the error path when such an allocation
6879 failed have been fixed.
6880
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006881Library
6882-------
6883
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006884- Issue #3612: Added some missing basic types in ctypes.wintypes.
6885
Benjamin Petersone977ad42008-08-20 01:42:01 +00006886- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6887 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6888
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006889- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6890 version reported by these tools does not necessarily follow the python
6891 version numbering scheme, so the module is less strict when parsing it.
6892
Nick Coghlanf70385a2008-08-18 12:42:46 +00006893- Issue #2235: Added Py3k warnings for types which will become unhashable
6894 under the stricter __hash__ inheritance rules in 3.0. Several types
6895 which did not meet the rules for hash invariants and were already
6896 unhashable in 3.0 have now been explicitly flagged as unhashable in
6897 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6898 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6899
Brett Cannon88f801d2008-08-18 00:46:22 +00006900- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6901 imported into the module but exposed as part of the module's API.
6902
Brett Cannon7b96f072008-08-18 00:41:11 +00006903- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6904
Brett Cannon46225e72008-08-18 00:36:52 +00006905- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6906
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006907- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6908
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006909- Issue #3575: Incremental decoder's decode function now takes bytearray
6910 by using 's*' instead of 't#'.
6911
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006912- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006913 fails unicode conversion on 2nd parameter. (windows only)
6914
Georg Brandl222e2082010-08-01 22:27:39 +00006915- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006916 in a redirect.
6917
Brett Cannonabe423e2008-08-16 21:47:07 +00006918- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006919 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006920
Facundo Batistaeb90b782008-08-16 14:44:07 +00006921- Issue #2776: fixed small issue when handling an URL with double slash
6922 after a 302 response in the case of not going through a proxy.
6923
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006924- Issue #2676: in the email package, content-type parsing was hanging on
6925 pathological input because of quadratic or exponential behaviour of a
6926 regular expression.
6927
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006928- Issue #3476: binary buffered reading through the new "io" library is now
6929 thread-safe.
6930
Brett Cannonbf3157b2008-08-14 05:00:03 +00006931- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6932 since mimetools itself is deprecated. Because modules are cached, all
6933 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6934
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006935- Issue #3134: shutil referenced undefined WindowsError symbol.
6936
Robert Schuppenies14646332008-08-10 11:01:53 +00006937- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6938 menu entries were not deleted.
6939
Brett Cannon83e81842008-08-09 23:30:55 +00006940- Copied the implementation of reduce() to _functools.reduce() to have a
6941 version that did not raise a DeprecationWarning under -3.
6942
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006943- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6944 a MemoryError rather than silently stop the iteration.
6945
Guido van Rossum59ce9012008-08-09 14:55:34 +00006946- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6947 to _sre.compile() will now be rejected. This should not affect anybody
6948 since the re.compile() function never generates invalid re-bytecode.
6949
Skip Montanaroa032bf42008-08-08 22:52:51 +00006950- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6951 upon first access it can be automatically initialized from the csv file if
6952 it wasn't initialized during instantiation.
6953
Brett Cannon3aa2a492008-08-06 22:28:09 +00006954- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6955 the reload() built-in has been removed.
6956
Brett Cannon7e30b672008-08-04 21:52:25 +00006957- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006958 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006959 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6960 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6961 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6962 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6963 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006964
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006965- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6966 raised an AttributeError.
6967
Benjamin Peterson01a24322008-07-28 23:35:27 +00006968- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006969 asking for a specific length. This problem only affected files opened
6970 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006971
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006972- Issue #3449: Update decimal module to use most recent specification
6973 (v. 1.68) and tests (v. 2.58) from IBM.
6974
Georg Brandl222e2082010-08-01 22:27:39 +00006975- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006976

Raymond Hettinger8c664e82008-07-25 18:43:33 +00006978 on a closed shelf.
6979
Georg Brandlf9efabb2008-07-23 15:16:45 +00006980- Deprecate the "ast" parser function aliases.
6981
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006982- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6983
6984- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6985 invalid arguments.
6986
6987- Issue #3302: Fix several crashes when calling locale's gettext functions
6988 with None arguments.
6989
6990- Issue #3389: Allow resolving dotted names for handlers in logging
6991 configuration files.
6992
6993- Deprecate the sunaudio module for removal in Python 3.0.
6994
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006995- Issue #3394: zipfile.writestr sets external attributes when passed a
6996 file name rather than a ZipInfo instance, so files are extracted with
6997 mode 0600 rather than 000 under Unix.
6998
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006999- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7000 argument in python 2.5, this broke code that subclassed Popen to include its
7001 own poll method. Fixed my moving _deadstate to an _internal_poll method.

7009-------------
7010
Nick Coghlan6e8fef02008-08-18 13:14:22 +00007011- Issue #2235: the C API function PyObject_HashNotImplemented and its
7012 interaction with the tp_hash slot (added in 2.6b2) are now documented
7013
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007014- Issue #643841: The language reference now provides more detailed
7015 coverage of the lookup process for special methods. The disclaimers
7016 regarding lack of coverage of new-style classes have also been
7017 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007020What's New in Python 2.6 beta 2?
7021================================
7022
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007023*Release date: 17-Jul-2008*
7024
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007025Core and Builtins
7026-----------------
7027
Georg Brandl3e483f62008-07-16 22:57:41 +00007028- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7029 its methods now allow for items objects that can be converted to
7030 an integer using operator.index().
7031
Mark Dickinson64b7e502008-07-16 09:40:03 +00007032- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7033 produced a ValueError instead of giving the correct float.
7034
Eric Smitha5fa5a22008-07-16 00:11:49 +00007035- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7036 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7037
Mark Dickinson7103aa42008-07-15 19:08:33 +00007038- Issue #3008: the float type has a new instance method 'float.hex'
7039 and a new class method 'float.fromhex' to convert floating-point
7040 numbers to and from hexadecimal strings, respectively.
7041
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007042- Issue #2235: __hash__ is once again inherited by default. To allow
7043 collections.Hashable to remain meaningful in the presence of the
7044 default hash implementation (object.__hash__), it is now possible
7045 to explicit block inheritance of hash by setting __hash__=None at
7046 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7047 level.
7048
Nick Coghlanb028f502008-07-13 14:52:36 +00007049- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7050 the parent module cannot be found while performing an absolute import.
7051 This means that an incorrectly defined __package__ attribute will
7052 now only prevent relative imports in that module rather than causing
7053 all imports from that module to fail.
7054
Nick Coghlan14ff9942008-07-08 14:21:42 +00007055- Issue #2517: Allow unicode messages in Exceptions again by correctly
7056 bypassing the instance dictionary when looking up __unicode__ on
7057 new-style classes.
7058
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007059- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7060 set to a custom object whose write() method happens to install
7061 another file in sys.stdout.
7062
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007063- Issue #3088: Corrected a race condition in classes derived from
7064 threading.local: the first member set by a thread could be saved in
7065 another thread's dictionary.
7066
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007067- Issue #3004: Minor change to slice.indices(): the start and stop
7068 arguments are now treated identically, making the behaviour easier
7069 to describe and understand. For example, slice(None, -10,
7070 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7071 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7072 10, -1).
7073
Georg Brandl278fc502008-07-19 12:46:12 +00007074- Issue #3219: Calling a function with repeated keyword arguments,
7075 f(a=2, a=23), would not cause a syntax error. This was a regression
7076 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007077
Georg Brandl278fc502008-07-19 12:46:12 +00007078- Issue #2862: Make int and float freelist management consistent with
7079 other freelists. Changes their CompactFreeList apis into
7080 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007081

Thomas Heller57adf222008-08-14 19:10:48 +00007085- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7086 api functions without holding the GIL, which could lead to a fatal
7087 error when they failed.
7088
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007089- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00007097- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7098 ForkingPickler.register() to resolve conflict with ctypes.
7099
Vinay Sajip51e65192008-07-18 09:01:10 +00007100- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

7103 a valid dlerror() message.
7104
Thomas Heller2bad6572008-07-15 17:19:50 +00007105- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7106 incomplete structure was created.
7107
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007108- Issue #3339: dummy_thread.acquire() should not return None.

7521
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007522- On MacOS X it is now possible to install the framework in 64-bit
7523 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007524 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007525
7526 This is controlled by the configure argument ``--with-universal-archs``:
7527
7528 - ``--with-universal-archs=all``: install 4-way universal
7529
7530 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7531
7532 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7533
7534 This option should be used in combination with ``--enable-universalsdk=``.
7535
7536 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7572 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007573
Christian Heimese74c8f22008-04-19 02:23:57 +00007574- Added kill, terminate and send_signal(sig) to subprocess.Popen.
7575
Georg Brandl3ee81df2008-05-17 18:14:43 +00007576- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
7577 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00007578

Georg Brandl3ee81df2008-05-17 18:14:43 +00007585- Issue #1631171: Re-implement the 'warnings' module in C (the
7586 original Python code has been kept as backup). This will allow for
7587 using the 'warning's machinery in such places as the parser where
7588 use of pure Python code is not possible. Both the ``showarning()``
7589 and ``formatwarning()`` gain an optional 'line' argument which is
7590 not called by default for backwards-compatibility reasons. Setting
7591 ``warnings.showwarning()`` to an implementation that lacks support
7592 for the ``line`` argument will raise a DeprecationWarning.

7616
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007617- The getpass module has been improved on Unix. It now uses /dev/tty
7618 by default and uses stderr instead of stdout. A GetPassWarning is
7619 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00007620

Georg Brandl3ee81df2008-05-17 18:14:43 +00007634- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007635 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007655- Issue #2550: The approach used by client/server code for obtaining
7656 ports to listen on in network-oriented tests has been refined in an
7657 effort to facilitate running multiple instances of the entire
7658 regression test suite in parallel without issue.
7659 test_support.bind_port() has been fixed such that it will always
7660 return a unique port -- which wasn't always the case with the
7661 previous implementation, especially if socket options had been set
7662 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7663 new implementation of bind_port() will actually raise an exception
7664 if it is passed an AF_INET/SOCK_STREAM socket with either the
7665 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7666 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7667 the socket it's been passed. This currently only applies to
7668 Windows. This option prevents any other sockets from binding to the
7669 host/port we've bound to, thus removing the possibility of the
7670 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7671 when a second SOCK_STREAM socket binds and accepts to a host/port
7672 that's already been bound by another socket. The optional preferred
7673 port parameter to bind_port() has been removed. Under no
7674 circumstances should tests be hard coding ports!
7675
7676 test_support.find_unused_port() has also been introduced, which will
7677 pass a temporary socket object to bind_port() in order to obtain an
7678 unused port. The temporary socket object is then closed and
7679 deleted, and the port is returned. This method should only be used
7680 for obtaining an unused port in order to pass to an external program
7681 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7682 a parameter to a server-oriented class that doesn't give you direct
7683 access to the underlying socket used.
7684
7685 Finally, test_support.HOST has been introduced, which should be used
7686 for the host argument of any relevant socket calls (i.e. bind and
7687 connect).

7692 test_asynchat and test_socket_ssl.
7693

7695 suite to run in parallel without issue.

7962-----------------
7963
Fred Drakea8ee94b2008-03-01 02:45:07 +00007964- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007965 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007966
Georg Brandlad61bc82008-02-23 15:11:18 +00007967- Issue #2067: file.__exit__() now calls subclasses' close() method.
7968
7969- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007970
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007971- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007972 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007973
Eric Smitha73fbe72008-02-23 03:09:44 +00007974- Added the future_builtins module, which contains hex() and oct().
7975 These are the PEP 3127 version of these functions, designed to be
7976 compatible with the hex() and oct() builtins from Python 3.0. They
7977 differ slightly in their output formats from the existing, unchanged
7978 Python 2.6 builtins. The expected usage of the future_builtins
7979 module is:
7980 from future_builtins import hex, oct
7981
Eric Smith7ef40bf2008-02-20 23:34:22 +00007982- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7983 exponents for exponents with absolute value < 100. Follows C99
7984 standard. This is a change on Windows, which would use 3 digits.
7985 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7986 so that any alterations it does to the resulting string will be
7987 available in stringlib/formatter.h (for float.__format__).
7988
Eric Smith5a3c1352008-02-19 13:21:56 +00007989- Implemented PEP 3101, Advanced String Formatting. This adds a new
7990 builtin format(); a format() method for str and unicode; a
7991 __format__() method to object, str, unicode, int, long, float, and
7992 datetime; the class string.Formatter; and the C API
7993 PyObject_Format().
7994
Georg Brandl3ee81df2008-05-17 18:14:43 +00007995- Fixed several potential crashes, all caused by specially crafted
7996 __del__ methods exploiting objects in temporarily inconsistent
7997 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007998
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007999- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008000 prevent a possible crash: an Abstract Base Class would try to access
8001 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008002
Georg Brandl3ee81df2008-05-17 18:14:43 +00008003- Fixed repr() and str() of complex numbers with infinity or nan as
8004 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008005
Georg Brandl3ee81df2008-05-17 18:14:43 +00008006- Clear all free lists during a gc.collect() of the highest generation
8007 in order to allow pymalloc to free more arenas. Python may give back
8008 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008009
Georg Brandl3ee81df2008-05-17 18:14:43 +00008010- Issue #2045: Fix an infinite recursion triggered when printing a
8011 subclass of collections.defaultdict, if its default_factory is set
8012 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008013
Christian Heimesf75dbef2008-02-08 00:11:31 +00008014- Fixed a minor memory leak in dictobject.c. The content of the free
8015 list was not freed on interpreter shutdown.
8016
Georg Brandl21e99f42010-03-07 15:23:59 +00008017- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008018 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008019
Georg Brandl3ee81df2008-05-17 18:14:43 +00008020- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8021 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008022 to compact the internal free lists of pre-allocted ints and floats.
8023
Georg Brandl3ee81df2008-05-17 18:14:43 +00008024- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8025 calls. Python expected the return type int but the fork familie
8026 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008027
Georg Brandl3ee81df2008-05-17 18:14:43 +00008028- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8029 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008030
Georg Brandl3ee81df2008-05-17 18:14:43 +00008031- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8032 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008033
Georg Brandl3ee81df2008-05-17 18:14:43 +00008034- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8035 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008036
Georg Brandl3ee81df2008-05-17 18:14:43 +00008037- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8038 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008039
Georg Brandl3ee81df2008-05-17 18:14:43 +00008040- Patch #1473257: generator objects gain a gi_code attribute. This is
8041 the same object as the func_code attribute of the function that
8042 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008043
Georg Brandl3ee81df2008-05-17 18:14:43 +00008044- Issue #1920: "while 0" statements were completely removed by the
8045 compiler, even in the presence of an "else" clause, which is
8046 supposed to be run when the condition is false. Now the compiler
8047 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008048
Guido van Rossumeead05f2008-01-24 18:21:02 +00008049- A few crashers fixed: weakref_in_del.py (issue #1377858);
8050 loosing_dict_ref.py (issue #1303614, test67.py);
8051 borrowed_ref_[34].py (not in tracker).
8052
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008053- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008054 suppressed while an extension is loaded by calling SetErrorMode in
8055 dynload_win.c. The error is still reported properly.
8056
Georg Brandl3ee81df2008-05-17 18:14:43 +00008057- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008058 several extension methods and modules do not work without unicode
8059 support.
8060
Georg Brandl26543b12008-01-21 18:36:51 +00008061- Issue #1882: when compiling code from a string, encoding cookies in the
8062 second line of code were not always recognized correctly.
8063
Georg Brandl14404b62008-01-19 19:27:05 +00008064- Issue #1679: "0x" was taken as a valid integer literal.
8065
Georg Brandl6caad7d2008-01-26 14:19:22 +00008066- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008067 added.
8068
Christian Heimesc94e2b52008-01-14 04:13:37 +00008069- sys.float_info / PyFloat_GetInfo: The floating point information
8070 object was converted from a dict to a specialized structseq object.
8071
Georg Brandl3ee81df2008-05-17 18:14:43 +00008072- Patch #1816: Added sys.flags structseq. It exposes the status of
8073 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008074
Georg Brandl3ee81df2008-05-17 18:14:43 +00008075- Objects/structseq.c: Implemented new structseq representation. The
8076 patch makes structseqs (e.g. the return value of os.stat) more
8077 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008078
Georg Brandl3ee81df2008-05-17 18:14:43 +00008079- Patch #1700288: added a type attribute cache that caches method
8080 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008081
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008082- Bug #1776: __import__() no longer accepts filenames on any platform.
8083 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008084

8086
Georg Brandl3ee81df2008-05-17 18:14:43 +00008087- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8088 envvar and sys.dont_write_bytecode attribute. All these can be set
8089 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008090
Georg Brandl3ee81df2008-05-17 18:14:43 +00008091- Improve some exception messages when Windows fails to load an
8092 extension module. Now we get for example '%1 is not a valid Win32
8093 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008094
Georg Brandl3ee81df2008-05-17 18:14:43 +00008095- Bug #1481296: Fixed long(float('nan')) != 0L.

8098 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008099
Christian Heimes0a8143f2007-12-18 23:22:54 +00008100- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008101 and INF. float("nan"), float("inf") and float("-inf") now work on
8102 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008103
Georg Brandl3ee81df2008-05-17 18:14:43 +00008104- Compiler now generates simpler and faster code for dictionary
8105 literals. The oparg for BUILD_MAP now indicates an estimated
8106 dictionary size. There is a new opcode, STORE_MAP, for adding
8107 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008141- Issue #1265: Fix a problem with sys.settrace, if the tracing
8142 function uses a generator expression when at the same time the
8143 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008144
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008145- sets and frozensets now have an isdisjoint() method.
8146

8150
Georg Brandl21e99f42010-03-07 15:23:59 +00008151- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008152 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8153 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008154
Georg Brandl3ee81df2008-05-17 18:14:43 +00008155- Issue #1686386: Tuple's tp_repr did not take into account the
8156 possibility of having a self-referential tuple, which is possible
8157 from C code. Nor did object's tp_str consider that a type's tp_str
8158 could do something that could lead to an inifinite recursion.
8159 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8160 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008161
Georg Brandl3ee81df2008-05-17 18:14:43 +00008162- Issue #1164: It was possible to trigger deadlock when using the
8163 'print' statement to write to a file since the GIL was not released
8164 as needed. Now PyObject_Print() does the right thing along with
8165 various tp_print implementations of the built-in types and those in
8166 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008168- Issue #1147: Exceptions were directly allowing string exceptions in
8169 their throw() method even though string exceptions no longer
8170 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008172- Issue #1096: Prevent a segfault from getting the repr of a very
8173 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00008175- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008176 PyObject_Call() never calling back out to Python code to trigger
8177 recursion depth updates/checks. Required the creation of a static
8178 RuntimeError instance in case normalizing an exception put the
8179 recursion check value past its limit. Fixes crashers
8180 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008195- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008196 __*__ attributes. (Some already existed, e.g., __doc__ and
8197 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008198
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008199- Add -3 option to the interpreter to warn about features that are
8200 deprecated and will be changed/removed in Python 3.0.
8201
Georg Brandl2134e752007-05-21 20:34:16 +00008202- Patch #1686487: you can now pass any mapping after '**' in function
8203 calls.
8204
Collin Winter62903052007-05-18 23:11:24 +00008205- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008206 "except E as target:". This is to provide forwards compatibility
8207 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008208
Brett Cannon229cee22007-05-05 01:34:02 +00008209- Deprecate BaseException.message as per PEP 352.
8210
Georg Brandl3ee81df2008-05-17 18:14:43 +00008211- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00008214- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008215 setting a plain string, ie don't expand to single letter identifiers.
8216
Raymond Hettinger13936692007-04-11 18:40:58 +00008217- Request #1191699: Slices can now be pickled.
8218
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008219- Request #1193128: str.translate() now allows a None argument for
8220 translations that only remove characters without re-mapping the
8221 remaining characters.
8222
Georg Brandl5cb76c12007-03-21 09:00:39 +00008223- Patch #1682205: a TypeError while unpacking an iterable is no longer

8225
Neal Norwitzaa754b72007-03-21 06:39:48 +00008226- Remove unused file Python/fmod.c.
8227
Guido van Rossum143b5642007-03-23 04:58:42 +00008228- Bug #1683368: The object.__init__() and object.__new__() methods are
8229 now stricter in rejecting excess arguments. The only time when
8230 either allows excess arguments is when it is not overridden and the
8231 other one is. For backwards compatibility, when both are
8232 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008233 warning later). Also, type.__init__() insists on the same signature
8234 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008235
Georg Brandl3ee81df2008-05-17 18:14:43 +00008236- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8237 object to complex using its __complex__() method before falling back
8238 to the __float__() method. Therefore, the functions in the cmath
8239 module now can operate on objects that define a __complex__()
8240 method.

8251 its type.

8257
Georg Brandl7b9c5552007-03-12 14:30:05 +00008258- Bug #1678647: write a newline after printing an exception in any
8259 case, even when converting the value to a string failed.
8260
Georg Brandl871f1bc2007-03-12 13:17:36 +00008261- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008262 its argument, if it exists. If not, it will work like before. This
8263 allows customizing the output of dir() in the presence of a
8264 __getattr__().

8273 parthensized forms. This means complex(repr(x)) now works instead of
8274 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008275
Georg Brandlaa2321b2007-03-07 00:40:28 +00008276- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008277 makes the filenames the warning module prints much more sensible
8278 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008279
Georg Brandl49aafc92007-03-07 00:34:46 +00008280- Variant of patch #697613: don't exit the interpreter on a SystemExit
8281 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008282 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00008291- Patch #1674228: when assigning a slice (old-style), check for the
8292 sq_ass_slice instead of the sq_slice slot.
8293
Georg Brandl3ee81df2008-05-17 18:14:43 +00008294- When printing an unraisable error, don't print exceptions. before

8904 Python would crash instead of raising an error.
8905
Thomas Hellerc2f77252007-03-09 19:21:28 +00008906- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
8907 returned string up to the first NUL character.

8918
Georg Brandl3ee81df2008-05-17 18:14:43 +00008919- unittest now verifies more of its assumptions. In particular,

8921 accepted in TestSuite.addTest(). This should cause no
8922 incompatibility since it never made sense with ordinary subclasses
8923 -- the failure just occurred later, with a more cumbersome
8924 exception.

9202 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009203
Georg Brandl3ee81df2008-05-17 18:14:43 +00009204- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009205 that the SMTP.starttls() caller no longer needs to call ehlo()
9206 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009207 does not claim to support starttls. Adds the
9208 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00009307 time so that opening a database previously created with the DB_DUP
9308 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9309 opens. Specifically: dictionary assignment to a DB object will
9310 replace all values for a given key when the database allows
9311 duplicate values. DB users should use DB.put(k, v) when they want
9312 to store duplicates; not DB[k] = v.

9319 characters with ASCII value less than 32. Also, it correctly quotes
9320 dots only if they occur on a single line, as opposed to the previous
9321 behavior of quoting dots if they are the second character of any
9322 line.

Neal Norwitz92422fb2006-08-18 03:57:54 +00009649C API
9650-----
9651
Georg Brandl3ee81df2008-05-17 18:14:43 +00009652- Unified naming convention for free lists and their limits. All free
9653 lists in Object/ are named ``free_list``, the counter ``numfree``
9654 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9655 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009656
Georg Brandl3ee81df2008-05-17 18:14:43 +00009657- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9658 to ``PyTuple_SetItem``, it can be used to populate a brand new
9659 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009660
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009661- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009663- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9664 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9665 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009666
9667- Patch #1720595: add T_BOOL to the range of structmember types.
9668
9669- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9670 ``PyFloat_GetInfo()`` to the float API.
9671
Georg Brandl3ee81df2008-05-17 18:14:43 +00009672- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9673 of w# format code incorrectly truncated the length to an int, even
9674 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9675 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009676
Georg Brandl3ee81df2008-05-17 18:14:43 +00009677- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9678 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009680- PEP 3123: Provide forward compatibility with Python 3.0, while
9681 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9682 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009683
Georg Brandl3ee81df2008-05-17 18:14:43 +00009684- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9685 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009686
9687- Patch #1733960: Allow T_LONGLONG to accept ints.

9695- Fix some leftovers from the conversion from int to Py_ssize_t
9696 (relevant to strings and sequences of more than 2**31 items).
9697
9698- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9699 outside of pystate.c and should not be necessary.
9700
Georg Brandl3ee81df2008-05-17 18:14:43 +00009701- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9702 absolute imports. In earlier versions they might have used relative
9703 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009704
Georg Brandl3ee81df2008-05-17 18:14:43 +00009705- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9706 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009707
Georg Brandl3ee81df2008-05-17 18:14:43 +00009708- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009714- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9715 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9716 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9717 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009718
Georg Brandl3ee81df2008-05-17 18:14:43 +00009719- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00009731- Removed the macfs module. It had been deprecated since Python 2.5.
9732 This lead to the deprecation of macostools.touched() as it relied
9733 solely on macfs and was a no-op under OS X.
