306 64-bit/32-bit installer for 10.6+. It is no longer necessary
307 to install a third-party version of Tcl/Tk 8.5 to work around the
308 problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
309 and later releases.

313 options like -fwrapv were overridden and thus not used, which could result
314 in broken interpreters when building with clang.

1362 32-bit-only installer Pythons on systems with Xcode 4 (currently
1363 OS X 10.8, 10.7, and optionally 10.6).
1364 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1365 * Since Xcode 4 removes ppc support, extension module builds now
1366 check for ppc compiler support and by default remove ppc and
1367 ppc64 archs when they are not available.
1368 * Extension module builds now revert to using system installed
1369 headers and libs (/usr and /System/Library) if the SDK used
1370 to build the interpreter is not installed or has moved.
1371 * Try to avoid building extension modules with deprecated
1372 and problematic Apple llvm-gcc compiler. If original compiler
1373 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001797- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001798 has left two versions of customize_compiler, the original in
1799 distutils.sysconfig and another copy in distutils.ccompiler, with some
1800 parts of distutils calling one and others using the other.
1801 Complete the revert back to only having one in distutils.sysconfig as
1802 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01001804- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1805 Distutils-based packages with C extension modules may fail because
1806 Apple has removed gcc-4.2, the version used to build python.org
1807 64-bit/32-bit Pythons. If the user does not explicitly override
1808 the default C compiler by setting the CC environment variable,
1809 Distutils will now attempt to compile extension modules with clang
1810 if gcc-4.2 is required but not found. Also as a convenience, if
1811 the user does explicitly set CC, substitute its value as the default
1812 compiler in the Distutils LDSHARED configuration variable for OS X.
1813 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1814 SDK, neither of which are available in Xcode 4. This change does not
1815 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002065- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2066 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2067 interpreter process. This could cause failures in non-Distutils subprocesses
2068 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002069 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002070 deployment target only in the environment of each build subprocess. It is
2071 still possible to globally override the default by setting
2072 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2073 greater or equal to the default value, the value with which the interpreter
2074 was built.

2103 updating the check interval, so if the user decreases the check interval,
2104 the ticker doesn't have to wind down to zero from the old starting point
2105 before the new interval takes effect. And if the user increases the
2106 interval, it makes sure the new limit takes effect right away rather have an
2107 early task switch before recognizing the new interval.

3088 This prevents user-created self-referencing ordered dictionaries from
3089 becoming permanently uncollectable GC garbage. The downside is that

3549
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003550- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3551 start byte and the continuation byte(s) are now considered invalid, instead
3552 of the number of bytes specified by the start byte.
3553 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3554 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3555 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3556 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003558- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of

3560 arises from the "Overriding __eq__ blocks inheritance ..." warning
3561 when turned into an exception: in this case the exception simply
3562 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003563
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003564- Issue #8748: Fix two issues with comparisons between complex and integer
3565 objects. (1) The comparison could incorrectly return True in some cases
3566 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3567 (2) The comparison raised an OverflowError for large integers, leading
3568 to unpredictable exceptions when combining integers and complex objects
3569 in sets or dicts.
3570
Mark Dickinson81336372010-05-30 12:12:25 +00003571- Issue #5211: Implicit coercion for the complex type is now completely
3572 removed. (Coercion for arithmetic operations was already removed in 2.7
3573 alpha 4, but coercion for rich comparisons was accidentally left in.)
3574
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003575- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00003762- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3763 operation raises multiple signals and more than one of those signals is
3764 trapped, the specification determines the order in which the signals should be
3765 handled. In many cases this order wasn't being followed, leading to the wrong
3766 Python exception being raised.

3952 with a non-empty format string. This is an effort to future-proof user
3953 code. If a derived class does not currently implement __format__ but later
3954 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003955 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003956 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004006- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4007 InvalidOperation instead of returning False. (Comparisons involving a quiet
4008 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4009 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004011- Issue #2531: Comparison operations between floats and Decimal instances now
4012 return a result based on the numeric values of the operands; previously they
4013 returned an arbitrary result based on the relative ordering of id(float) and
4014 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004016- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004017 argument `-` which tells it to read files to compile from stdin. Each line is
4018 read on demand and the named file is compiled immediately. (Original patch by
4019 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00004028- Comparisons using one of <, <=, >, >= between a complex instance and a
4029 Fractions instance now raise TypeError instead of returning True/False. This
4030 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4031 <=> complex, and complex <=> complex comparisons.

4131 integer format code, struct.pack first attempts to convert the non-integer

4134
Georg Brandlba83f822010-03-14 09:50:54 +00004135- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4136 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4137 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004138 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4139 inconsistent: __int__ was used for some integer codes but not for others, and
4140 the set of integer codes for which it was used differed between native packing
4141 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004449 file position when calling `truncate()`. It would previously change the file
4450 position to the given argument, which goes against the tradition of

4454 class used to represent files stored inside an archive. The new
4455 implementation is significantly faster and can be wrapped in a
4456 ``io.BufferedReader`` object for more speedups. It also solves an issue

Georg Brandlba83f822010-03-14 09:50:54 +00004548- The ``__complex__()`` method is now looked up on the class of instances to
4549 make it consistent with other special methods.

4553
Mark Dickinson1b34d252010-01-01 17:27:30 +00004554- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004555 DeprecationWarning when passed a float argument where an integer was expected.
4556 These functions and methods now raise TypeError instead. The majority of the
4557 effects of this change are in the extension modules, but some core functions
4558 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4559 and many unicode/str methods.

4574 least on IEEE 754 platforms), and in particular does not depend on the
4575 internal representation of a long.

4583
Georg Brandlba83f822010-03-14 09:50:54 +00004584 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004720- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
4721 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00004723- Issue #3382: 'F' formatting for float and complex now convert the result to
4724 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4725 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004726
Georg Brandlba83f822010-03-14 09:50:54 +00004727- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4728 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004729
Georg Brandlba83f822010-03-14 09:50:54 +00004730- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4731 1e-100 used to raise OverflowError, but now gives the requested 120
4732 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004733
Georg Brandlba83f822010-03-14 09:50:54 +00004734- Add Py3k warnings for parameter names in parentheses.

4739 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004740
Georg Brandlba83f822010-03-14 09:50:54 +00004741- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4742 decimal string that's guaranteed to round back to x under correct rounding
4743 (with round-half-to-even rounding mode). Previously it gave a string based on
4744 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4745 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4746 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004747
Georg Brandlba83f822010-03-14 09:50:54 +00004748- Issue #7117: On almost all platforms: float-to-string and string-to-float
4749 conversions within Python are now correctly rounded. Places these conversions
4750 occur include: str for floats and complex numbers; the float and complex
4751 constructors; old-style and new-style numeric formatting; serialization and
4752 deserialization of floats and complex numbers using marshal, pickle and json;
4753 parsing of float and imaginary literals in Python code; Decimal-to-float
4754 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004755
Georg Brandlba83f822010-03-14 09:50:54 +00004756 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4757 providing correctly-rounded strtod and dtoa C functions. This code is
4758 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4759 the C compiler. There may be a small number of platforms on which correct
4760 operation of this code cannot be guaranteed, so the code is not used: notably,
4761 this applies to platforms where the C double format is not IEEE 754 binary64,
4762 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4763 and Python's configure script is unable to determine how to change the FPU
4764 precision. On these platforms conversions use the platform strtod and dtoa,
4765 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004766
Georg Brandlba83f822010-03-14 09:50:54 +00004767- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4768 uses the correctly-rounded string <-> float conversions described above (when
4769 available), and so produces correctly rounded results that will display nicely
4770 under the float repr. There are two related small changes: (1) round now
4771 accepts any class with an ``__index__()`` method for its second argument (but
4772 no longer accepts floats for the second argument), and (2) an excessively
4773 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4774 raises an exception.

4777
Georg Brandlba83f822010-03-14 09:50:54 +00004778- Fix several issues with ``compile()``. The input can now contain Windows and

4923 but with at least one decimal point and with a default precision
4924 of 12. Previously, the behavior the same but with a default precision of 6.
4925 This more closely matches ``str()``, and reduces surprises when adding

Antoine Pitrouf8387af2009-03-23 18:41:45 +00004991- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00004992 untrackable objects are not tracked by the garbage collector. This can reduce
4993 the size of collections and therefore the garbage collection overhead on
4994 long-running programs, depending on their particular use of datatypes.

5001 internal representation of integers, for performance reasons. Base 2**30 is
5002 enabled by default on 64-bit machines. Add --enable-big-digits option to
5003 configure, which overrides the default. Add sys.long_info structseq to
5004 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00005016- Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a
Brett Cannon6c4cff02009-03-11 04:51:06 +00005017 requirement. Means the DeprecationWarning from Python 2.6 can go away.
5018
Georg Brandlba83f822010-03-14 09:50:54 +00005019- Issue #5247: Improve error message when unknown format codes are used when
5020 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00005021
Georg Brandlba83f822010-03-14 09:50:54 +00005022- Running Python with the -3 option now also warns about classic division for

Benjamin Petersone18ef192009-01-20 14:21:16 +00005034- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
5035
Georg Brandl29c6a282009-04-05 20:23:13 +00005036- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00005037 were suppressing all exceptions. These include list(), filter(), map(),
5038 zip(), and bytearray().
5039
Benjamin Peterson596d3062009-01-19 15:42:23 +00005040- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00005048- Issue #4935: The overflow checking code in the expandtabs() method common to
5049 str, bytes and bytearray could be optimized away by the compiler, letting the
5050 interpreter segfault instead of raising an error.

Georg Brandlba83f822010-03-14 09:50:54 +00005067- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5068 existing .py counterpart, override the co_filename attributes of all code
5069 objects if the original filename is obsolete (which can happen if the file has
5070 been renamed, moved, or if it is accessed through different paths). Patch by

5124
Georg Brandlba83f822010-03-14 09:50:54 +00005125- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5126 file objects with closefd=False. The file descriptor is still kept open but
5127 the file object behaves like a closed file. The ``FileIO`` object also got a

5153 this code path is really executed because I cannot move to such directory on
5154 win2k)

6557
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006558- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6559
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006560- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6561 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6562 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6563 ``printf`` function, whereas PyString_FromFormat has an independent
6564 implementation and uses "%zd" on all platforms for size_t values.
6565 This makes a difference on win64, where ``printf`` needs "%Id" to display
6566 64bit values.
6567
Benjamin Peterson97179b02008-09-09 20:55:01 +00006568- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6569 error.
6570
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006571- Issue #3777: long() applied to a float object now always return a long
6572 object; previously an int would be returned for small values. the __long__
6573 method is allowed to return either an int or a long, but the behaviour of
6574 float objects should not change to respect backward compatibility.
6575
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006576- Issue #3751: str.rpartition would perform a left-partition when called with
6577 a unicode argument.
6578
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006579- Issue #3683: Fix compilation when --without-threads is given.
6580
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006581- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006582 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006583 was correctly parsed but parsing of subsequent arguments failed.
6584
Vinay Sajip35e3b032008-09-01 14:33:59 +00006585- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006586 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6587 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6588 when given a tuple of classes as second argument, were looking up
6589 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6590 type object.
6591
Neal Norwitz18aa3882008-08-24 05:04:52 +00006592- Fix crashes on memory allocation failure found with failmalloc.
6593
6594- Fix memory leaks found with valgrind and update suppressions file.
6595
6596- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6597
6598- Fix problem using wrong name in decimal module reported by pychecker.
6599
Christian Heimes7d4c3172008-08-22 19:47:25 +00006600- Silenced another compiler warning about a used but not defined
6601 function 'stringlib_contains_obj'.
6602
Benjamin Peterson712ee922008-08-24 18:10:20 +00006603- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6604 ``__delslice__``.
6605

6607 library targets in the Makefile.
6608
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006609- Issue #1204: The configure script now tests for additional libraries
6610 that may be required when linking against readline. This fixes issues
6611 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00006661 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6662 for catch_warnings() also led to an improvement in the raising of a
6663 DeprecationWarning related to warnings.warn_explicit().
6664
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006665- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006729What's New in Python 2.6 beta 3?
6730================================
6731
Barry Warsaw07a4a382008-08-21 01:15:08 +00006732*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006733
6734Core and Builtins
6735-----------------
6736
Guido van Rossumf8402962008-08-20 15:01:50 +00006737- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6738 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6739 extensions do not automatically benefit from the class attribute
6740 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6741 to their tp_flags field if they care. This is a backwards
6742 compatibility feature; in 3.0, all types will use the cache by
6743 default.
6744
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006745- Keyword arguments can now follow starred arguments. (``f(a, *args,
6746 keyword=23)`` is now valid syntax.)
6747
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006748- ctypes function pointers that are COM methods have a boolean True
6749 value again.
6750
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006751- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6752 by denying s# to parse objects that have a releasebuffer procedure,
6753 and introducing s*.
6754
Georg Brandl1e13ea92008-08-11 09:07:59 +00006755- Issue #3537: Fix an assertion failure when an empty but presized dict
6756 object was stored in the freelist.
6757
Mark Dickinsonb6467572008-08-04 21:30:09 +00006758- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6759 ValueError consistently across platforms.
6760
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006761- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6762 (64bit Unix, for example), unichr() would truncate its argument and return
6763 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6764
Neal Norwitze7d8be82008-07-31 17:17:14 +00006765- Apply security patches from Apple.
6766
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006767- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6768 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6769
Antoine Pitrou92f82162008-07-25 22:22:08 +00006770- Issue #1819: function calls with several named parameters are now on
6771 average 35% faster (as measured by pybench).
6772
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006773- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6774 the python debugger steps into a class statement: the free variables (local
6775 variables defined in an outer scope) would be deleted from the outer scope.
6776
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006777- Issue #2620: Overflow checking when allocating or reallocating memory
6778 was not always being done properly in some python types and extension
6779 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6780 all been updated to perform better checks and places in the code that
6781 would previously leak memory on the error path when such an allocation
6782 failed have been fixed.

6790 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6791
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006792- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6793 version reported by these tools does not necessarily follow the python
6794 version numbering scheme, so the module is less strict when parsing it.
6795
Nick Coghlanf70385a2008-08-18 12:42:46 +00006796- Issue #2235: Added Py3k warnings for types which will become unhashable
6797 under the stricter __hash__ inheritance rules in 3.0. Several types
6798 which did not meet the rules for hash invariants and were already
6799 unhashable in 3.0 have now been explicitly flagged as unhashable in
6800 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6801 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6802
Brett Cannon88f801d2008-08-18 00:46:22 +00006803- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6804 imported into the module but exposed as part of the module's API.
6805

6811
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006812- Issue #3575: Incremental decoder's decode function now takes bytearray
6813 by using 's*' instead of 't#'.
6814
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006815- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006816 fails unicode conversion on 2nd parameter. (windows only)
6817
Georg Brandl222e2082010-08-01 22:27:39 +00006818- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006819 in a redirect.
6820

Brett Cannon721b1452008-08-16 22:00:27 +00006822 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006823
Facundo Batistaeb90b782008-08-16 14:44:07 +00006824- Issue #2776: fixed small issue when handling an URL with double slash
6825 after a 302 response in the case of not going through a proxy.
6826
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006827- Issue #2676: in the email package, content-type parsing was hanging on
6828 pathological input because of quadratic or exponential behaviour of a
6829 regular expression.
6830
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006831- Issue #3476: binary buffered reading through the new "io" library is now

6835 since mimetools itself is deprecated. Because modules are cached, all
6836 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

Antoine Pitroude781a42008-08-09 12:43:23 +00006872 asking for a specific length. This problem only affected files opened

6916
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006917- Issue #643841: The language reference now provides more detailed

6930
Georg Brandl3e483f62008-07-16 22:57:41 +00006931- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6932 its methods now allow for items objects that can be converted to
6933 an integer using operator.index().
6934
Mark Dickinson64b7e502008-07-16 09:40:03 +00006935- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6936 produced a ValueError instead of giving the correct float.
6937
Eric Smitha5fa5a22008-07-16 00:11:49 +00006938- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

6940
Mark Dickinson7103aa42008-07-15 19:08:33 +00006941- Issue #3008: the float type has a new instance method 'float.hex'
6942 and a new class method 'float.fromhex' to convert floating-point
6943 numbers to and from hexadecimal strings, respectively.
6944
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006945- Issue #2235: __hash__ is once again inherited by default. To allow
6946 collections.Hashable to remain meaningful in the presence of the
6947 default hash implementation (object.__hash__), it is now possible
6948 to explicit block inheritance of hash by setting __hash__=None at
6949 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6950 level.
6951
Nick Coghlanb028f502008-07-13 14:52:36 +00006952- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6953 the parent module cannot be found while performing an absolute import.
6954 This means that an incorrectly defined __package__ attribute will
6955 now only prevent relative imports in that module rather than causing
6956 all imports from that module to fail.
6957
Nick Coghlan14ff9942008-07-08 14:21:42 +00006958- Issue #2517: Allow unicode messages in Exceptions again by correctly

6968 another thread's dictionary.
6969
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006970- Issue #3004: Minor change to slice.indices(): the start and stop
6971 arguments are now treated identically, making the behaviour easier
6972 to describe and understand. For example, slice(None, -10,
6973 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6974 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6975 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00006977- Issue #3219: Calling a function with repeated keyword arguments,
6978 f(a=2, a=23), would not cause a syntax error. This was a regression
6979 from 2.4 caused by the switch to the new compiler.

7018 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007019 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007020 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007036- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Vinay Sajip9828b7e2008-06-17 11:04:02 +00007405- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007406 environment to control the '-arch' flags that are used to build
7407 an extension. This was added for compatibility with Apple's build
7408 of Python.
7409
7410- The bundled OSX-specific copy of libbffi is now in sync with the version
7411 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.

Brett Cannonb61d8012008-05-11 23:39:04 +00007423- ``Lib/lib-old`` is now added to sys.path.
7424
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007425- On MacOS X it is now possible to install the framework in 64-bit
7426 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007427 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007428
7429 This is controlled by the configure argument ``--with-universal-archs``:
7430
7431 - ``--with-universal-archs=all``: install 4-way universal
7432
7433 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7434
7435 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7436
7437 This option should be used in combination with ``--enable-universalsdk=``.
7438
7439 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 +00007488- Issue #1631171: Re-implement the 'warnings' module in C (the
7489 original Python code has been kept as backup). This will allow for
7490 using the 'warning's machinery in such places as the parser where
7491 use of pure Python code is not possible. Both the ``showarning()``
7492 and ``formatwarning()`` gain an optional 'line' argument which is
7493 not called by default for backwards-compatibility reasons. Setting
7494 ``warnings.showwarning()`` to an implementation that lacks support
7495 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007558- Issue #2550: The approach used by client/server code for obtaining
7559 ports to listen on in network-oriented tests has been refined in an
7560 effort to facilitate running multiple instances of the entire
7561 regression test suite in parallel without issue.
7562 test_support.bind_port() has been fixed such that it will always
7563 return a unique port -- which wasn't always the case with the
7564 previous implementation, especially if socket options had been set
7565 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7566 new implementation of bind_port() will actually raise an exception
7567 if it is passed an AF_INET/SOCK_STREAM socket with either the
7568 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7569 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7570 the socket it's been passed. This currently only applies to
7571 Windows. This option prevents any other sockets from binding to the
7572 host/port we've bound to, thus removing the possibility of the
7573 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7574 when a second SOCK_STREAM socket binds and accepts to a host/port
7575 that's already been bound by another socket. The optional preferred
7576 port parameter to bind_port() has been removed. Under no
7577 circumstances should tests be hard coding ports!
7578
7579 test_support.find_unused_port() has also been introduced, which will
7580 pass a temporary socket object to bind_port() in order to obtain an
7581 unused port. The temporary socket object is then closed and
7582 deleted, and the port is returned. This method should only be used
7583 for obtaining an unused port in order to pass to an external program
7584 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7585 a parameter to a server-oriented class that doesn't give you direct
7586 access to the underlying socket used.
7587
7588 Finally, test_support.HOST has been introduced, which should be used
7589 for the host argument of any relevant socket calls (i.e. bind and
7590 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007591
7592 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007593 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007594 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7595 test_asynchat and test_socket_ssl.
7596
Georg Brandl3ee81df2008-05-17 18:14:43 +00007597 It is now possible for multiple instances of the regression test
7598 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007877- Added the future_builtins module, which contains hex() and oct().
7878 These are the PEP 3127 version of these functions, designed to be
7879 compatible with the hex() and oct() builtins from Python 3.0. They
7880 differ slightly in their output formats from the existing, unchanged
7881 Python 2.6 builtins. The expected usage of the future_builtins
7882 module is:
7883 from future_builtins import hex, oct
7884
Eric Smith7ef40bf2008-02-20 23:34:22 +00007885- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7886 exponents for exponents with absolute value < 100. Follows C99
7887 standard. This is a change on Windows, which would use 3 digits.
7888 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7889 so that any alterations it does to the resulting string will be
7890 available in stringlib/formatter.h (for float.__format__).
7891
Eric Smith5a3c1352008-02-19 13:21:56 +00007892- Implemented PEP 3101, Advanced String Formatting. This adds a new
7893 builtin format(); a format() method for str and unicode; a
7894 __format__() method to object, str, unicode, int, long, float, and
7895 datetime; the class string.Formatter; and the C API
7896 PyObject_Format().
7897
Georg Brandl3ee81df2008-05-17 18:14:43 +00007898- Fixed several potential crashes, all caused by specially crafted
7899 __del__ methods exploiting objects in temporarily inconsistent
7900 state.

7910 in order to allow pymalloc to free more arenas. Python may give back
7911 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007912
Georg Brandl3ee81df2008-05-17 18:14:43 +00007913- Issue #2045: Fix an infinite recursion triggered when printing a
7914 subclass of collections.defaultdict, if its default_factory is set
7915 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007916
Christian Heimesf75dbef2008-02-08 00:11:31 +00007917- Fixed a minor memory leak in dictobject.c. The content of the free
7918 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00007920- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007921 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007922
Georg Brandl3ee81df2008-05-17 18:14:43 +00007923- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7924 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007925 to compact the internal free lists of pre-allocted ints and floats.
7926
Georg Brandl3ee81df2008-05-17 18:14:43 +00007927- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7928 calls. Python expected the return type int but the fork familie
7929 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007930
Georg Brandl3ee81df2008-05-17 18:14:43 +00007931- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7932 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007933
Georg Brandl3ee81df2008-05-17 18:14:43 +00007934- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7935 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007936
Georg Brandl3ee81df2008-05-17 18:14:43 +00007937- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7938 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00007940- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7941 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007942
Georg Brandl3ee81df2008-05-17 18:14:43 +00007943- Patch #1473257: generator objects gain a gi_code attribute. This is
7944 the same object as the func_code attribute of the function that
7945 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007946
Georg Brandl3ee81df2008-05-17 18:14:43 +00007947- Issue #1920: "while 0" statements were completely removed by the
7948 compiler, even in the presence of an "else" clause, which is
7949 supposed to be run when the condition is false. Now the compiler
7950 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007951
Guido van Rossumeead05f2008-01-24 18:21:02 +00007952- A few crashers fixed: weakref_in_del.py (issue #1377858);
7953 loosing_dict_ref.py (issue #1303614, test67.py);
7954 borrowed_ref_[34].py (not in tracker).
7955
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007956- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007957 suppressed while an extension is loaded by calling SetErrorMode in
7958 dynload_win.c. The error is still reported properly.
7959
Georg Brandl3ee81df2008-05-17 18:14:43 +00007960- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007961 several extension methods and modules do not work without unicode
7962 support.
7963
Georg Brandl26543b12008-01-21 18:36:51 +00007964- Issue #1882: when compiling code from a string, encoding cookies in the
7965 second line of code were not always recognized correctly.
7966
Georg Brandl14404b62008-01-19 19:27:05 +00007967- Issue #1679: "0x" was taken as a valid integer literal.
7968
Georg Brandl6caad7d2008-01-26 14:19:22 +00007969- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007970 added.
7971
Christian Heimesc94e2b52008-01-14 04:13:37 +00007972- sys.float_info / PyFloat_GetInfo: The floating point information
7973 object was converted from a dict to a specialized structseq object.
7974
Georg Brandl3ee81df2008-05-17 18:14:43 +00007975- Patch #1816: Added sys.flags structseq. It exposes the status of
7976 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007977
Georg Brandl3ee81df2008-05-17 18:14:43 +00007978- Objects/structseq.c: Implemented new structseq representation. The
7979 patch makes structseqs (e.g. the return value of os.stat) more
7980 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007981
Georg Brandl3ee81df2008-05-17 18:14:43 +00007982- Patch #1700288: added a type attribute cache that caches method
7983 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007984
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007985- Bug #1776: __import__() no longer accepts filenames on any platform.
7986 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007987
Georg Brandlaed6c662008-01-07 17:25:53 +00007988- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7989
Georg Brandl3ee81df2008-05-17 18:14:43 +00007990- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7991 envvar and sys.dont_write_bytecode attribute. All these can be set
7992 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007993
Georg Brandl3ee81df2008-05-17 18:14:43 +00007994- Improve some exception messages when Windows fails to load an
7995 extension module. Now we get for example '%1 is not a valid Win32
7996 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007997
Georg Brandl3ee81df2008-05-17 18:14:43 +00007998- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008000- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8001 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008002
Christian Heimes0a8143f2007-12-18 23:22:54 +00008003- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008004 and INF. float("nan"), float("inf") and float("-inf") now work on
8005 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008006
Georg Brandl3ee81df2008-05-17 18:14:43 +00008007- Compiler now generates simpler and faster code for dictionary
8008 literals. The oparg for BUILD_MAP now indicates an estimated
8009 dictionary size. There is a new opcode, STORE_MAP, for adding
8010 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008011
Georg Brandl3ee81df2008-05-17 18:14:43 +00008012- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008020- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008021 SystemError.
8022
Nick Coghlanef01d822007-12-03 12:55:17 +00008023- PEP 366: Allow explicit relative imports when executing modules
8024 inside packages with the -m switch via a new module level
8025 __package__ attribute.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008039- Patch #1739468: Directories and zipfiles containing a __main__.py
8040 file can now be directly executed by passing their name to the
8041 interpreter. The directory/zipfile is automatically inserted as the
8042 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008043
Georg Brandl3ee81df2008-05-17 18:14:43 +00008044- Issue #1265: Fix a problem with sys.settrace, if the tracing
8045 function uses a generator expression when at the same time the
8046 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008047
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008048- sets and frozensets now have an isdisjoint() method.
8049
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008050- optimize the performance of builtin.sum().
8051
Neal Norwitz44f326e2007-10-05 05:29:17 +00008052- Fix warnings found by the new version of the Coverity checker.
8053
Georg Brandl21e99f42010-03-07 15:23:59 +00008054- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008055 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8056 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008057
Georg Brandl3ee81df2008-05-17 18:14:43 +00008058- Issue #1686386: Tuple's tp_repr did not take into account the
8059 possibility of having a self-referential tuple, which is possible
8060 from C code. Nor did object's tp_str consider that a type's tp_str
8061 could do something that could lead to an inifinite recursion.
8062 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8063 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008064
Georg Brandl3ee81df2008-05-17 18:14:43 +00008065- Issue #1164: It was possible to trigger deadlock when using the
8066 'print' statement to write to a file since the GIL was not released
8067 as needed. Now PyObject_Print() does the right thing along with
8068 various tp_print implementations of the built-in types and those in
8069 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008070
Georg Brandl3ee81df2008-05-17 18:14:43 +00008071- Issue #1147: Exceptions were directly allowing string exceptions in
8072 their throw() method even though string exceptions no longer
8073 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008074
Georg Brandl3ee81df2008-05-17 18:14:43 +00008075- Issue #1096: Prevent a segfault from getting the repr of a very
8076 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008077
Brett Cannon1e534b52007-09-07 04:18:30 +00008078- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008079 PyObject_Call() never calling back out to Python code to trigger
8080 recursion depth updates/checks. Required the creation of a static
8081 RuntimeError instance in case normalizing an exception put the
8082 recursion check value past its limit. Fixes crashers
8083 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008084
Georg Brandl3ee81df2008-05-17 18:14:43 +00008085- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008098- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099 __*__ attributes. (Some already existed, e.g., __doc__ and
8100 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008101
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008102- Add -3 option to the interpreter to warn about features that are
8103 deprecated and will be changed/removed in Python 3.0.
8104
Georg Brandl2134e752007-05-21 20:34:16 +00008105- Patch #1686487: you can now pass any mapping after '**' in function
8106 calls.
8107
Collin Winter62903052007-05-18 23:11:24 +00008108- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008109 "except E as target:". This is to provide forwards compatibility
8110 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008111
Brett Cannon229cee22007-05-05 01:34:02 +00008112- Deprecate BaseException.message as per PEP 352.
8113
Georg Brandl3ee81df2008-05-17 18:14:43 +00008114- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008115 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008116
Vinay Sajip8549ce32007-05-06 17:53:37 +00008117- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008118 setting a plain string, ie don't expand to single letter identifiers.
8119
Raymond Hettinger13936692007-04-11 18:40:58 +00008120- Request #1191699: Slices can now be pickled.
8121
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008122- Request #1193128: str.translate() now allows a None argument for
8123 translations that only remove characters without re-mapping the
8124 remaining characters.
8125
Georg Brandl5cb76c12007-03-21 09:00:39 +00008126- Patch #1682205: a TypeError while unpacking an iterable is no longer
8127 masked by a generic one with the message "unpack non-sequence".
8128
Neal Norwitzaa754b72007-03-21 06:39:48 +00008129- Remove unused file Python/fmod.c.
8130
Guido van Rossum143b5642007-03-23 04:58:42 +00008131- Bug #1683368: The object.__init__() and object.__new__() methods are
8132 now stricter in rejecting excess arguments. The only time when
8133 either allows excess arguments is when it is not overridden and the
8134 other one is. For backwards compatibility, when both are
8135 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008136 warning later). Also, type.__init__() insists on the same signature
8137 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008138
Georg Brandl3ee81df2008-05-17 18:14:43 +00008139- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8140 object to complex using its __complex__() method before falling back
8141 to the __float__() method. Therefore, the functions in the cmath
8142 module now can operate on objects that define a __complex__()
8143 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008145- Patch #1623563: allow __class__ assignment for classes with
8146 __slots__. The old and the new class are still required to have the
8147 same slot names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008731 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00009210 time so that opening a database previously created with the DB_DUP
9211 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9212 opens. Specifically: dictionary assignment to a DB object will
9213 replace all values for a given key when the database allows
9214 duplicate values. DB users should use DB.put(k, v) when they want
9215 to store duplicates; not DB[k] = v.

9224 behavior of quoting dots if they are the second character of any
9225 line.
