987- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
988 and later systems as is currently done for Python 3.x installers.
989 For 2.7.7 only, we will provide three installers:
990 the legacy deprecated 10.3+ 32-bit-only format;
991 the newer 10.5+ 32-bit-only format;
992 and the unchanged 10.6+ 64-/32-bit format.
993 Although binary installers will no longer be available from
994 python.org as of 2.7.8, it will still be possible to build from
995 source on 10.3.9 and 10.4 systems if necessary.
996 See Mac/BuildScript/README.txt for more information.

2377 In particular, fix extension module build failures when trying to use
2378 32-bit-only installer Pythons on systems with Xcode 4 (currently
2379 OS X 10.8, 10.7, and optionally 10.6).
2380 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2381 * Since Xcode 4 removes ppc support, extension module builds now
2382 check for ppc compiler support and by default remove ppc and
2383 ppc64 archs when they are not available.
2384 * Extension module builds now revert to using system installed
2385 headers and libs (/usr and /System/Library) if the SDK used
2386 to build the interpreter is not installed or has moved.
2387 * Try to avoid building extension modules with deprecated
2388 and problematic Apple llvm-gcc compiler. If original compiler

2739
Mark Hammond323b5da2011-10-17 11:05:36 +11002740- Issue #7833: Extension modules built using distutils on Windows will no
2741 longer include a "manifest" to prevent them failing at import time in some
2742 embedded situations.
2743
Benjamin Petersona7b09762011-10-15 13:43:21 -04002744- Issue #13186: Fix __delitem__ on old-style instances when invoked through

2752
Mark Dickinsondbbed042011-09-19 16:38:08 +01002753- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2754 int.__pow__. These overflow checks were causing int.__pow__ to produce
2755 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002756 compiler optimizing the check away. Also fix similar overflow checks
2757 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2758 bugs caused test failures with recent versions of Clang.
Mark Dickinsondbbed042011-09-19 16:38:08 +01002759

2767 non-exception class.
Benjamin Petersonc3349cd2011-07-15 14:15:40 -05002768
Antoine Pitrou16166452011-07-12 22:04:20 +02002769- Issue #12149: Update the method cache after a type's dictionnary gets
2770 cleared by the garbage collector. This fixes a segfault when an instance
2771 and its type get caught in a reference cycle, and the instance's
2772 deallocator calls one of the methods on the type (e.g. when subclassing
2773 IOBase). Diagnosis and patch by Davide Rizzo.
2774
Florent Xiclunaa1f948b2012-01-24 21:05:10 +01002775- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02002782 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
2783 raw_input() interrupted by CTRL+c.
2784
Łukasz Langa7a153902011-10-18 17:16:00 +02002785- Issue #10860: httplib now correctly handles an empty port after port
2786 delimiter in URLs.
2787

2825
Florent Xiclunac2279652012-02-12 14:49:03 +01002826- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002827 has left two versions of customize_compiler, the original in
2828 distutils.sysconfig and another copy in distutils.ccompiler, with some
2829 parts of distutils calling one and others using the other.
2830 Complete the revert back to only having one in distutils.sysconfig as
2831 is the case in 3.x.
2832
Ned Deily0d0ea482012-02-10 12:59:06 +01002833- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2834 Distutils-based packages with C extension modules may fail because
2835 Apple has removed gcc-4.2, the version used to build python.org
2836 64-bit/32-bit Pythons. If the user does not explicitly override
2837 the default C compiler by setting the CC environment variable,
2838 Distutils will now attempt to compile extension modules with clang
2839 if gcc-4.2 is required but not found. Also as a convenience, if
2840 the user does explicitly set CC, substitute its value as the default
2841 compiler in the Distutils LDSHARED configuration variable for OS X.
2842 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2843 SDK, neither of which are available in Xcode 4. This change does not
2844 attempt to override settings to support their use with Xcode 4.)
2845

Senthil Kumaran607e31e2012-02-09 17:43:31 +08002848- Issue #6005: Examples in the socket library documentation use sendall, where
2849 relevant, instead send method.
2850
Petri Lehtinenc7fd5232011-05-09 12:24:09 +02002851- Issue #10811: Fix recursive usage of cursors. Instead of crashing,

2853
Petri Lehtinen0518f472012-02-01 22:20:12 +02002854- Issue #13676: Handle strings with embedded zeros correctly in sqlite3.

Ned Deily87e82bb2011-06-28 19:52:59 -07003094- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3095 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3096 interpreter process. This could cause failures in non-Distutils subprocesses
3097 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003098 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003099 deployment target only in the environment of each build subprocess. It is
3100 still possible to globally override the default by setting
3101 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3102 greater or equal to the default value, the value with which the interpreter
3103 was built.

3130
Barry Warsawc5643282011-07-19 17:06:30 -04003131- sys.setcheckinterval() now updates the current ticker count as well as
3132 updating the check interval, so if the user decreases the check interval,
3133 the ticker doesn't have to wind down to zero from the old starting point
3134 before the new interval takes effect. And if the user increases the
3135 interval, it makes sure the new limit takes effect right away rather have an
3136 early task switch before recognizing the new interval.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004596- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4597 start byte and the continuation byte(s) are now considered invalid, instead
4598 of the number of bytes specified by the start byte.
4599 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4600 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4601 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004610- Issue #8748: Fix two issues with comparisons between complex and integer
4611 objects. (1) The comparison could incorrectly return True in some cases
4612 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4613 (2) The comparison raised an OverflowError for large integers, leading
4614 to unpredictable exceptions when combining integers and complex objects
4615 in sets or dicts.

4755 non-float non-integer argument is now converted to an integer (if possible)
4756 using its __int__ method. Previously, only small arguments were treated this

Georg Brandlfee0f442010-05-22 21:26:21 +00004808- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4809 operation raises multiple signals and more than one of those signals is
4810 trapped, the specification determines the order in which the signals should be
4811 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00004956- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004957 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
4958 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
4959 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

4979Core and Builtins
4980-----------------
4981
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004982- Issue #7301: Add environment variable $PYTHONWARNINGS.
4983
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004984- Issue #8329: Don't return the same lists from select.select when no fds are
4985 changed.
4986
Georg Brandlfee0f442010-05-22 21:26:21 +00004987- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004988 on 64-bit machines. The shift count for either left or right shift is
4989 permitted to be up to sys.maxsize.
4990
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004991- Ensure that tokenization of identifiers is not affected by locale.
4992
Georg Brandlfee0f442010-05-22 21:26:21 +00004993- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004994
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004995- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4996
Georg Brandlfee0f442010-05-22 21:26:21 +00004997- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4998 with a non-empty format string. This is an effort to future-proof user
4999 code. If a derived class does not currently implement __format__ but later
5000 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005001 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005002 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00005003
Antoine Pitroua57df2c2010-03-31 21:32:15 +00005004- Issue #8268: Old-style classes (not just instances) now support weak
5005 references.
5006

5008 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00005009

5016
Victor Stinner66644262010-03-10 22:30:19 +00005017- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00005018 (SIGINT). If an error occurs while importing the site module, the error is
5019 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00005020 module.

5028
Antoine Pitrouf9de5342010-04-05 21:35:07 +00005029- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00005030 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Benjamin Peterson76a23c12010-04-04 23:23:22 +00005033- Issue #8310: Allow dis to examine new style classes.
5034
Georg Brandlfee0f442010-05-22 21:26:21 +00005035- Issue #8257: The Decimal construct now accepts a float instance directly,
5036 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005037
5038 >>> Decimal(1.1)
5039 Decimal('1.100000000000000088817841970012523233890533447265625')
5040
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005041- collections.Counter() now supports a subtract() method.
5042
Georg Brandlfee0f442010-05-22 21:26:21 +00005043- The functools module now has a total_ordering() class decorator to simplify
5044 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00005045
Georg Brandlfee0f442010-05-22 21:26:21 +00005046- The functools module also adds cmp_to_key() as a tool to transition old-style
5047 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005048
Georg Brandlfee0f442010-05-22 21:26:21 +00005049- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5050 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00005051
Georg Brandlfee0f442010-05-22 21:26:21 +00005052- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5053 InvalidOperation instead of returning False. (Comparisons involving a quiet
5054 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5055 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005056
Georg Brandlfee0f442010-05-22 21:26:21 +00005057- Issue #2531: Comparison operations between floats and Decimal instances now
5058 return a result based on the numeric values of the operands; previously they
5059 returned an arbitrary result based on the relative ordering of id(float) and
5060 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005061
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005062- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005063 argument `-` which tells it to read files to compile from stdin. Each line is
5064 read on demand and the named file is compiled immediately. (Original patch by
5065 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005066
Georg Brandlfee0f442010-05-22 21:26:21 +00005067- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
5068 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00005070- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5071 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005072 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005073
Georg Brandlfee0f442010-05-22 21:26:21 +00005074- Comparisons using one of <, <=, >, >= between a complex instance and a
5075 Fractions instance now raise TypeError instead of returning True/False. This
5076 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5077 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00005078

5087
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005088- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00005089 didn't support chflags() (for example ZFS under FreeBSD). The error is now
5090 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005091
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00005092- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
5093 deprecated.
5094
Georg Brandlfee0f442010-05-22 21:26:21 +00005095- Issue #7860: platform.uname now reports the correct 'machine' type when Python
5096 is running in WOW64 mode on 64 bit Windows.

5103 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00005104
Georg Brandlfee0f442010-05-22 21:26:21 +00005105- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded

Vinay Sajipecfa08f2010-03-12 09:16:10 +00005132- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00005133 for ``TimedRotatingFileHandler`` by using the modification time of an existing
5134 log file to compute the next rollover time. If the log file does not exist,
5135 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00005136

Georg Brandlba83f822010-03-14 09:50:54 +00005145- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
5146 a base64 transfer-encoded payload *after* decoding it; it no longer does.
5147 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00005176- Issue #8300: When passing a non-integer argument to struct.pack with any
5177 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00005181- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
5182 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
5183 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00005184 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5185 inconsistent: __int__ was used for some integer codes but not for others, and
5186 the set of integer codes for which it was used differed between native packing
5187 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00005594- The ``__complex__()`` method is now looked up on the class of instances to

5602 These functions and methods now raise TypeError instead. The majority of the
5603 effects of this change are in the extension modules, but some core functions
5604 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5605 and many unicode/str methods.

5620 least on IEEE 754 platforms), and in particular does not depend on the
5621 internal representation of a long.

5629
Georg Brandlba83f822010-03-14 09:50:54 +00005630 These executables now work properly with the arch(1) command: ``arch -ppc
5631 python`` will start a universal binary version of python in PPC mode (unlike

5771 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005772
Georg Brandlba83f822010-03-14 09:50:54 +00005773- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5774 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005775
Georg Brandlba83f822010-03-14 09:50:54 +00005776- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005786
Georg Brandlba83f822010-03-14 09:50:54 +00005787- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5788 decimal string that's guaranteed to round back to x under correct rounding
5789 (with round-half-to-even rounding mode). Previously it gave a string based on
5790 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5791 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5792 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005793
Georg Brandlba83f822010-03-14 09:50:54 +00005794- Issue #7117: On almost all platforms: float-to-string and string-to-float
5795 conversions within Python are now correctly rounded. Places these conversions
5796 occur include: str for floats and complex numbers; the float and complex
5797 constructors; old-style and new-style numeric formatting; serialization and
5798 deserialization of floats and complex numbers using marshal, pickle and json;
5799 parsing of float and imaginary literals in Python code; Decimal-to-float
5800 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005801
Georg Brandlba83f822010-03-14 09:50:54 +00005802 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5803 providing correctly-rounded strtod and dtoa C functions. This code is
5804 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5805 the C compiler. There may be a small number of platforms on which correct
5806 operation of this code cannot be guaranteed, so the code is not used: notably,
5807 this applies to platforms where the C double format is not IEEE 754 binary64,
5808 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5809 and Python's configure script is unable to determine how to change the FPU
5810 precision. On these platforms conversions use the platform strtod and dtoa,
5811 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005812
Georg Brandlba83f822010-03-14 09:50:54 +00005813- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5814 uses the correctly-rounded string <-> float conversions described above (when
5815 available), and so produces correctly rounded results that will display nicely
5816 under the float repr. There are two related small changes: (1) round now
5817 accepts any class with an ``__index__()`` method for its second argument (but
5818 no longer accepts floats for the second argument), and (2) an excessively
5819 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5820 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005967- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5968 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5969 but with at least one decimal point and with a default precision
5970 of 12. Previously, the behavior the same but with a default precision of 6.
5971 This more closely matches ``str()``, and reduces surprises when adding
5972 alignment flags to the empty presentation type. This also affects the new
5973 complex.__format__ in the same way.

6170
Georg Brandlba83f822010-03-14 09:50:54 +00006171- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6172 file objects with closefd=False. The file descriptor is still kept open but
6173 the file object behaves like a closed file. The ``FileIO`` object also got a
6174 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00006197- On windows, ``os.chdir()`` given unicode was not working if
6198 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6199 this code path is really executed because I cannot move to such directory on
6200 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006202- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6203 element is temporarily replaced with an equivalent frozenset. But the
6204 eventual KeyError would always report the empty ``frozenset()`` as the missing
6205 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00006225- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6226 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6227 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6228 of using the replace error handler in PyUnicode_DecodeUTF8().
6229
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006230- Issue #3739: The unicode-internal encoder now reports the number of characters

6232
Georg Brandlba83f822010-03-14 09:50:54 +00006233- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

6235 gives improved memory leak detection when running under Valgrind, while taking
6236 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00007502- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
7503 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00007504 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
7505 the tests if DISPLAY is defined but can't be used.

7509
Georg Brandlba83f822010-03-14 09:50:54 +00007510- Issue #5354: New test support function import_fresh_module() makes it easy to
7511 import both normal and optimised versions of modules. test_heapq and
7512 test_warnings have been adjusted to use it, tests for other modules with both
7513 C and Python implementations in the stdlib can be adjusted to use it over
7514 time.

Georg Brandlba83f822010-03-14 09:50:54 +00007522- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
7523 should cause a test to be skipped are now done using import_module from test
7524 support, which does the conversion.

7626
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007627- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7628 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7629 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7630 ``printf`` function, whereas PyString_FromFormat has an independent
7631 implementation and uses "%zd" on all platforms for size_t values.
7632 This makes a difference on win64, where ``printf`` needs "%Id" to display
7633 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00007635- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

7639 object; previously an int would be returned for small values. the __long__
7640 method is allowed to return either an int or a long, but the behaviour of
7641 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00007650 was correctly parsed but parsing of subsequent arguments failed.
7651
Vinay Sajip35e3b032008-09-01 14:33:59 +00007652- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007653 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7654 mechanism. In the process, fix a bug where isinstance() and issubclass(),
7655 when given a tuple of classes as second argument, were looking up
7656 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7657 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007796What's New in Python 2.6 beta 3?
7797================================
7798
Barry Warsaw07a4a382008-08-21 01:15:08 +00007799*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007800
7801Core and Builtins
7802-----------------
7803
Guido van Rossumf8402962008-08-20 15:01:50 +00007804- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7805 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7806 extensions do not automatically benefit from the class attribute
7807 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7808 to their tp_flags field if they care. This is a backwards
7809 compatibility feature; in 3.0, all types will use the cache by
7810 default.
7811
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007812- Keyword arguments can now follow starred arguments. (``f(a, *args,
7813 keyword=23)`` is now valid syntax.)
7814
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007815- ctypes function pointers that are COM methods have a boolean True
7816 value again.
7817
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007818- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7819 by denying s# to parse objects that have a releasebuffer procedure,
7820 and introducing s*.
7821
Georg Brandl1e13ea92008-08-11 09:07:59 +00007822- Issue #3537: Fix an assertion failure when an empty but presized dict
7823 object was stored in the freelist.
7824
Mark Dickinsonb6467572008-08-04 21:30:09 +00007825- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7826 ValueError consistently across platforms.
7827
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007828- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7829 (64bit Unix, for example), unichr() would truncate its argument and return
7830 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7831
Neal Norwitze7d8be82008-07-31 17:17:14 +00007832- Apply security patches from Apple.
7833
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007834- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7835 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7836
Antoine Pitrou92f82162008-07-25 22:22:08 +00007837- Issue #1819: function calls with several named parameters are now on
7838 average 35% faster (as measured by pybench).
7839
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007840- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7841 the python debugger steps into a class statement: the free variables (local
7842 variables defined in an outer scope) would be deleted from the outer scope.
7843
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007844- Issue #2620: Overflow checking when allocating or reallocating memory
7845 was not always being done properly in some python types and extension
7846 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7847 all been updated to perform better checks and places in the code that
7848 would previously leak memory on the error path when such an allocation
7849 failed have been fixed.

7852-------
7853
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007854- Issue #3612: Added some missing basic types in ctypes.wintypes.
7855
Benjamin Petersone977ad42008-08-20 01:42:01 +00007856- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7857 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7858
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007859- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7860 version reported by these tools does not necessarily follow the python
7861 version numbering scheme, so the module is less strict when parsing it.
7862
Nick Coghlanf70385a2008-08-18 12:42:46 +00007863- Issue #2235: Added Py3k warnings for types which will become unhashable
7864 under the stricter __hash__ inheritance rules in 3.0. Several types
7865 which did not meet the rules for hash invariants and were already
7866 unhashable in 3.0 have now been explicitly flagged as unhashable in
7867 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7868 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7869
Brett Cannon88f801d2008-08-18 00:46:22 +00007870- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7871 imported into the module but exposed as part of the module's API.
7872
Brett Cannon7b96f072008-08-18 00:41:11 +00007873- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7874
Brett Cannon46225e72008-08-18 00:36:52 +00007875- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
7876
Brett Cannon25c9d6a2008-08-17 22:10:11 +00007877- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7878
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007879- Issue #3575: Incremental decoder's decode function now takes bytearray
7880 by using 's*' instead of 't#'.
7881
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007882- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007883 fails unicode conversion on 2nd parameter. (windows only)
7884
Georg Brandl222e2082010-08-01 22:27:39 +00007885- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007886 in a redirect.
7887
Brett Cannonabe423e2008-08-16 21:47:07 +00007888- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007889 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007890
Facundo Batistaeb90b782008-08-16 14:44:07 +00007891- Issue #2776: fixed small issue when handling an URL with double slash
7892 after a 302 response in the case of not going through a proxy.
7893
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007894- Issue #2676: in the email package, content-type parsing was hanging on
7895 pathological input because of quadratic or exponential behaviour of a
7896 regular expression.
7897
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007898- Issue #3476: binary buffered reading through the new "io" library is now
7899 thread-safe.
7900
Brett Cannonbf3157b2008-08-14 05:00:03 +00007901- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7902 since mimetools itself is deprecated. Because modules are cached, all
7903 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7904
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007905- Issue #3134: shutil referenced undefined WindowsError symbol.
7906
Robert Schuppenies14646332008-08-10 11:01:53 +00007907- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7908 menu entries were not deleted.
7909
Brett Cannon83e81842008-08-09 23:30:55 +00007910- Copied the implementation of reduce() to _functools.reduce() to have a
7911 version that did not raise a DeprecationWarning under -3.
7912
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007913- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7914 a MemoryError rather than silently stop the iteration.
7915
Guido van Rossum59ce9012008-08-09 14:55:34 +00007916- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7917 to _sre.compile() will now be rejected. This should not affect anybody
7918 since the re.compile() function never generates invalid re-bytecode.
7919
Skip Montanaroa032bf42008-08-08 22:52:51 +00007920- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7921 upon first access it can be automatically initialized from the csv file if
7922 it wasn't initialized during instantiation.
7923
Brett Cannon3aa2a492008-08-06 22:28:09 +00007924- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7925 the reload() built-in has been removed.
7926
Brett Cannon7e30b672008-08-04 21:52:25 +00007927- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007928 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

7933 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00007934
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00007935- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
7936 raised an AttributeError.
7937
Benjamin Peterson01a24322008-07-28 23:35:27 +00007938- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00007939 asking for a specific length. This problem only affected files opened
7940 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007941
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007942- Issue #3449: Update decimal module to use most recent specification
7943 (v. 1.68) and tests (v. 2.58) from IBM.
7944
Georg Brandl222e2082010-08-01 22:27:39 +00007945- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00007946

7949
Georg Brandlf9efabb2008-07-23 15:16:45 +00007950- Deprecate the "ast" parser function aliases.
7951
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007952- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
7953
7954- Issue #3303: Fix a crash in locale.strcoll() when calling it with
7955 invalid arguments.
7956
7957- Issue #3302: Fix several crashes when calling locale's gettext functions
7958 with None arguments.
7959
7960- Issue #3389: Allow resolving dotted names for handlers in logging
7961 configuration files.
7962
7963- Deprecate the sunaudio module for removal in Python 3.0.
7964
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00007965- Issue #3394: zipfile.writestr sets external attributes when passed a
7966 file name rather than a ZipInfo instance, so files are extracted with
7967 mode 0600 rather than 000 under Unix.
7968
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007969- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
7970 argument in python 2.5, this broke code that subclassed Popen to include its
7971 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00007981- Issue #2235: the C API function PyObject_HashNotImplemented and its
7982 interaction with the tp_hash slot (added in 2.6b2) are now documented
7983
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007984- Issue #643841: The language reference now provides more detailed
7985 coverage of the lookup process for special methods. The disclaimers
7986 regarding lack of coverage of new-style classes have also been
7987 removed, since the coverage is now fairly reasonable.

7996-----------------
7997
Georg Brandl3e483f62008-07-16 22:57:41 +00007998- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7999 its methods now allow for items objects that can be converted to
8000 an integer using operator.index().
8001
Mark Dickinson64b7e502008-07-16 09:40:03 +00008002- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8003 produced a ValueError instead of giving the correct float.
8004
Eric Smitha5fa5a22008-07-16 00:11:49 +00008005- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8006 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8007
Mark Dickinson7103aa42008-07-15 19:08:33 +00008008- Issue #3008: the float type has a new instance method 'float.hex'
8009 and a new class method 'float.fromhex' to convert floating-point
8010 numbers to and from hexadecimal strings, respectively.
8011
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008012- Issue #2235: __hash__ is once again inherited by default. To allow
8013 collections.Hashable to remain meaningful in the presence of the
8014 default hash implementation (object.__hash__), it is now possible
8015 to explicit block inheritance of hash by setting __hash__=None at
8016 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8017 level.
8018
Nick Coghlanb028f502008-07-13 14:52:36 +00008019- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8020 the parent module cannot be found while performing an absolute import.
8021 This means that an incorrectly defined __package__ attribute will
8022 now only prevent relative imports in that module rather than causing
8023 all imports from that module to fail.
8024
Nick Coghlan14ff9942008-07-08 14:21:42 +00008025- Issue #2517: Allow unicode messages in Exceptions again by correctly
8026 bypassing the instance dictionary when looking up __unicode__ on
8027 new-style classes.
8028
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008029- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8030 set to a custom object whose write() method happens to install
8031 another file in sys.stdout.

8035 another thread's dictionary.
8036
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008037- Issue #3004: Minor change to slice.indices(): the start and stop
8038 arguments are now treated identically, making the behaviour easier
8039 to describe and understand. For example, slice(None, -10,
8040 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8041 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8042 10, -1).
8043
Georg Brandl278fc502008-07-19 12:46:12 +00008044- Issue #3219: Calling a function with repeated keyword arguments,
8045 f(a=2, a=23), would not cause a syntax error. This was a regression
8046 from 2.4 caused by the switch to the new compiler.

8493 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00008494 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008495
8496 This is controlled by the configure argument ``--with-universal-archs``:
8497
8498 - ``--with-universal-archs=all``: install 4-way universal
8499
8500 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8501
8502 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8503
8504 This option should be used in combination with ``--enable-universalsdk=``.
8505
8506 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008555- Issue #1631171: Re-implement the 'warnings' module in C (the
8556 original Python code has been kept as backup). This will allow for
8557 using the 'warning's machinery in such places as the parser where
8558 use of pure Python code is not possible. Both the ``showarning()``
8559 and ``formatwarning()`` gain an optional 'line' argument which is
8560 not called by default for backwards-compatibility reasons. Setting
8561 ``warnings.showwarning()`` to an implementation that lacks support
8562 for the ``line`` argument will raise a DeprecationWarning.

8586
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00008587- The getpass module has been improved on Unix. It now uses /dev/tty
8588 by default and uses stderr instead of stdout. A GetPassWarning is
8589 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00008590

Georg Brandl3ee81df2008-05-17 18:14:43 +00008604- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008605 extension modules between 32 and 64 bit platforms. See the distutls

8619 script environment. This supports setup.py scripts that refer to
8620 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008625- Issue #2550: The approach used by client/server code for obtaining
8626 ports to listen on in network-oriented tests has been refined in an
8627 effort to facilitate running multiple instances of the entire
8628 regression test suite in parallel without issue.
8629 test_support.bind_port() has been fixed such that it will always
8630 return a unique port -- which wasn't always the case with the
8631 previous implementation, especially if socket options had been set
8632 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8633 new implementation of bind_port() will actually raise an exception
8634 if it is passed an AF_INET/SOCK_STREAM socket with either the
8635 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8636 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8637 the socket it's been passed. This currently only applies to
8638 Windows. This option prevents any other sockets from binding to the
8639 host/port we've bound to, thus removing the possibility of the
8640 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8641 when a second SOCK_STREAM socket binds and accepts to a host/port
8642 that's already been bound by another socket. The optional preferred
8643 port parameter to bind_port() has been removed. Under no
8644 circumstances should tests be hard coding ports!
8645
8646 test_support.find_unused_port() has also been introduced, which will
8647 pass a temporary socket object to bind_port() in order to obtain an
8648 unused port. The temporary socket object is then closed and
8649 deleted, and the port is returned. This method should only be used
8650 for obtaining an unused port in order to pass to an external program
8651 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8652 a parameter to a server-oriented class that doesn't give you direct
8653 access to the underlying socket used.
8654
8655 Finally, test_support.HOST has been introduced, which should be used
8656 for the host argument of any relevant socket calls (i.e. bind and
8657 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008658
8659 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008660 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008661 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8662 test_asynchat and test_socket_ssl.
8663
Georg Brandl3ee81df2008-05-17 18:14:43 +00008664 It is now possible for multiple instances of the regression test
8665 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008944- Added the future_builtins module, which contains hex() and oct().
8945 These are the PEP 3127 version of these functions, designed to be
8946 compatible with the hex() and oct() builtins from Python 3.0. They
8947 differ slightly in their output formats from the existing, unchanged
8948 Python 2.6 builtins. The expected usage of the future_builtins
8949 module is:
8950 from future_builtins import hex, oct
8951
Eric Smith7ef40bf2008-02-20 23:34:22 +00008952- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8953 exponents for exponents with absolute value < 100. Follows C99
8954 standard. This is a change on Windows, which would use 3 digits.
8955 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8956 so that any alterations it does to the resulting string will be
8957 available in stringlib/formatter.h (for float.__format__).
8958
Eric Smith5a3c1352008-02-19 13:21:56 +00008959- Implemented PEP 3101, Advanced String Formatting. This adds a new
8960 builtin format(); a format() method for str and unicode; a
8961 __format__() method to object, str, unicode, int, long, float, and
8962 datetime; the class string.Formatter; and the C API
8963 PyObject_Format().
8964
Georg Brandl3ee81df2008-05-17 18:14:43 +00008965- Fixed several potential crashes, all caused by specially crafted
8966 __del__ methods exploiting objects in temporarily inconsistent
8967 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008968
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008969- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008970 prevent a possible crash: an Abstract Base Class would try to access
8971 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008972

Georg Brandl3ee81df2008-05-17 18:14:43 +00008976- Clear all free lists during a gc.collect() of the highest generation
8977 in order to allow pymalloc to free more arenas. Python may give back
8978 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008979
Georg Brandl3ee81df2008-05-17 18:14:43 +00008980- Issue #2045: Fix an infinite recursion triggered when printing a
8981 subclass of collections.defaultdict, if its default_factory is set
8982 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008983
Christian Heimesf75dbef2008-02-08 00:11:31 +00008984- Fixed a minor memory leak in dictobject.c. The content of the free
8985 list was not freed on interpreter shutdown.
8986
Georg Brandl21e99f42010-03-07 15:23:59 +00008987- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008988 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008989
Georg Brandl3ee81df2008-05-17 18:14:43 +00008990- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8991 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008992 to compact the internal free lists of pre-allocted ints and floats.
8993
Georg Brandl3ee81df2008-05-17 18:14:43 +00008994- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8995 calls. Python expected the return type int but the fork familie
8996 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008997
Georg Brandl3ee81df2008-05-17 18:14:43 +00008998- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00009010- Patch #1473257: generator objects gain a gi_code attribute. This is
9011 the same object as the func_code attribute of the function that
9012 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009013
Georg Brandl3ee81df2008-05-17 18:14:43 +00009014- Issue #1920: "while 0" statements were completely removed by the
9015 compiler, even in the presence of an "else" clause, which is
9016 supposed to be run when the condition is false. Now the compiler
9017 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009018
Guido van Rossumeead05f2008-01-24 18:21:02 +00009019- A few crashers fixed: weakref_in_del.py (issue #1377858);
9020 loosing_dict_ref.py (issue #1303614, test67.py);
9021 borrowed_ref_[34].py (not in tracker).
9022
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00009023- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00009024 suppressed while an extension is loaded by calling SetErrorMode in
9025 dynload_win.c. The error is still reported properly.
9026
Georg Brandl3ee81df2008-05-17 18:14:43 +00009027- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009028 several extension methods and modules do not work without unicode
9029 support.
9030
Georg Brandl26543b12008-01-21 18:36:51 +00009031- Issue #1882: when compiling code from a string, encoding cookies in the
9032 second line of code were not always recognized correctly.
9033
Georg Brandl14404b62008-01-19 19:27:05 +00009034- Issue #1679: "0x" was taken as a valid integer literal.
9035
Georg Brandl6caad7d2008-01-26 14:19:22 +00009036- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009037 added.
9038
Christian Heimesc94e2b52008-01-14 04:13:37 +00009039- sys.float_info / PyFloat_GetInfo: The floating point information
9040 object was converted from a dict to a specialized structseq object.
9041
Georg Brandl3ee81df2008-05-17 18:14:43 +00009042- Patch #1816: Added sys.flags structseq. It exposes the status of
9043 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009044
Georg Brandl3ee81df2008-05-17 18:14:43 +00009045- Objects/structseq.c: Implemented new structseq representation. The
9046 patch makes structseqs (e.g. the return value of os.stat) more
9047 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009048
Georg Brandl3ee81df2008-05-17 18:14:43 +00009049- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00009071 and INF. float("nan"), float("inf") and float("-inf") now work on
9072 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009073
Georg Brandl3ee81df2008-05-17 18:14:43 +00009074- Compiler now generates simpler and faster code for dictionary
9075 literals. The oparg for BUILD_MAP now indicates an estimated
9076 dictionary size. There is a new opcode, STORE_MAP, for adding
9077 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00009121- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009122 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9123 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009124
Georg Brandl3ee81df2008-05-17 18:14:43 +00009125- Issue #1686386: Tuple's tp_repr did not take into account the
9126 possibility of having a self-referential tuple, which is possible
9127 from C code. Nor did object's tp_str consider that a type's tp_str
9128 could do something that could lead to an inifinite recursion.
9129 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9130 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009132- Issue #1164: It was possible to trigger deadlock when using the
9133 'print' statement to write to a file since the GIL was not released
9134 as needed. Now PyObject_Print() does the right thing along with
9135 various tp_print implementations of the built-in types and those in
9136 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009137
Georg Brandl3ee81df2008-05-17 18:14:43 +00009138- Issue #1147: Exceptions were directly allowing string exceptions in
9139 their throw() method even though string exceptions no longer
9140 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009141
Georg Brandl3ee81df2008-05-17 18:14:43 +00009142- Issue #1096: Prevent a segfault from getting the repr of a very
9143 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009144
Brett Cannon1e534b52007-09-07 04:18:30 +00009145- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009146 PyObject_Call() never calling back out to Python code to trigger
9147 recursion depth updates/checks. Required the creation of a static
9148 RuntimeError instance in case normalizing an exception put the
9149 recursion check value past its limit. Fixes crashers
9150 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009151

Neal Norwitz0ac60192007-05-27 04:08:54 +00009165- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009166 __*__ attributes. (Some already existed, e.g., __doc__ and
9167 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009168
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009169- Add -3 option to the interpreter to warn about features that are
9170 deprecated and will be changed/removed in Python 3.0.
9171
Georg Brandl2134e752007-05-21 20:34:16 +00009172- Patch #1686487: you can now pass any mapping after '**' in function
9173 calls.
9174
Collin Winter62903052007-05-18 23:11:24 +00009175- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009176 "except E as target:". This is to provide forwards compatibility
9177 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009184- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009185 setting a plain string, ie don't expand to single letter identifiers.
9186
Raymond Hettinger13936692007-04-11 18:40:58 +00009187- Request #1191699: Slices can now be pickled.
9188
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009189- Request #1193128: str.translate() now allows a None argument for
9190 translations that only remove characters without re-mapping the
9191 remaining characters.
9192
Georg Brandl5cb76c12007-03-21 09:00:39 +00009193- Patch #1682205: a TypeError while unpacking an iterable is no longer

9197
Guido van Rossum143b5642007-03-23 04:58:42 +00009198- Bug #1683368: The object.__init__() and object.__new__() methods are
9199 now stricter in rejecting excess arguments. The only time when
9200 either allows excess arguments is when it is not overridden and the
9201 other one is. For backwards compatibility, when both are
9202 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009203 warning later). Also, type.__init__() insists on the same signature
9204 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009205
Georg Brandl3ee81df2008-05-17 18:14:43 +00009206- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9207 object to complex using its __complex__() method before falling back
9208 to the __float__() method. Therefore, the functions in the cmath
9209 module now can operate on objects that define a __complex__()
9210 method.

9221 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00009228- Bug #1678647: write a newline after printing an exception in any
9229 case, even when converting the value to a string failed.
9230
Georg Brandl871f1bc2007-03-12 13:17:36 +00009231- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009232 its argument, if it exists. If not, it will work like before. This
9233 allows customizing the output of dir() in the presence of a
9234 __getattr__().

9243 parthensized forms. This means complex(repr(x)) now works instead of
9244 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009245
Georg Brandlaa2321b2007-03-07 00:40:28 +00009246- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009247 makes the filenames the warning module prints much more sensible
9248 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00009261- Patch #1674228: when assigning a slice (old-style), check for the
9262 sq_ass_slice instead of the sq_slice slot.
9263
Georg Brandl3ee81df2008-05-17 18:14:43 +00009264- When printing an unraisable error, don't print exceptions. before
9265 the name. This duplicates the behavior whening normally printing
9266 exceptions.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +000010105- ctypes callback functions only support 'fundamental' data types as
10106 result type. Raise an error when something else is used. This is a
10107 partial fix for Bug #1574584.
10108
Georg Brandl3ee81df2008-05-17 18:14:43 +000010109- Fix turtle so that time.sleep is imported for the entire library.

10162 the first chunk fed to the decoder started with a BOM, but was
10163 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010164
Georg Brandl3ee81df2008-05-17 18:14:43 +000010165- The implementation of UnicodeError objects has been simplified
10166 (start and end attributes are now stored directly as Py_ssize_t
10167 members).

10171 obtained from the TLS negotiation itself. Patch contributed by Bill
10172 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +000010173
Georg Brandl3ee81df2008-05-17 18:14:43 +000010174- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010175 that the SMTP.starttls() caller no longer needs to call ehlo()
10176 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010177 does not claim to support starttls. Adds the
10178 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
10179 Fenner.

Georg Brandl309501a2008-01-19 20:22:13 +000010220
Georg Brandl3ee81df2008-05-17 18:14:43 +000010221- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010222 works as expected. ``mmap.find`` also takes an optional ``end``
10223 parameter.
10224

10259 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10260 silently miscode subclasses of those types. Now, it raises a
10261 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +000010262

Georg Brandl3ee81df2008-05-17 18:14:43 +000010277 time so that opening a database previously created with the DB_DUP
10278 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10279 opens. Specifically: dictionary assignment to a DB object will
10280 replace all values for a given key when the database allows
10281 duplicate values. DB users should use DB.put(k, v) when they want
10282 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010283

Georg Brandl3ee81df2008-05-17 18:14:43 +000010288- Patch #1185447: binascii.b2a_qp() now correctly quotes binary
10289 characters with ASCII value less than 32. Also, it correctly quotes
10290 dots only if they occur on a single line, as opposed to the previous
10291 behavior of quoting dots if they are the second character of any
10292 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010293
Georg Brandla47337f2007-03-13 12:34:25 +000010294- Bug #1622896: fix a rare corner case where the bz2 module raised an

10621
Georg Brandl3ee81df2008-05-17 18:14:43 +000010622- Unified naming convention for free lists and their limits. All free
10623 lists in Object/ are named ``free_list``, the counter ``numfree``
10624 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10625 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010626
Georg Brandl3ee81df2008-05-17 18:14:43 +000010627- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10628 to ``PyTuple_SetItem``, it can be used to populate a brand new
10629 frozenset; but it does not steal a reference to the added item.

10641
Georg Brandl3ee81df2008-05-17 18:14:43 +000010642- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10643 of w# format code incorrectly truncated the length to an int, even
10644 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10645 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010646
Georg Brandl3ee81df2008-05-17 18:14:43 +000010647- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

10664
10665- Fix some leftovers from the conversion from int to Py_ssize_t
10666 (relevant to strings and sequences of more than 2**31 items).
10667
10668- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10669 outside of pystate.c and should not be necessary.
10670
Georg Brandl3ee81df2008-05-17 18:14:43 +000010671- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10672 absolute imports. In earlier versions they might have used relative
10673 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010674
Georg Brandl3ee81df2008-05-17 18:14:43 +000010675- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10676 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010677
Georg Brandl3ee81df2008-05-17 18:14:43 +000010678- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +000010684- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10685 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10686 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10687 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010688

Georg Brandl3ee81df2008-05-17 18:14:43 +000010701- Removed the macfs module. It had been deprecated since Python 2.5.
10702 This lead to the deprecation of macostools.touched() as it relied
10703 solely on macfs and was a no-op under OS X.
