16 is modified during the lifetime of the Python process after zipimport has
17 already cached the zip's table of contents we detect this and recover
18 rather than read bad data from the .zip (causing odd import errors).

29 destroyed while the generator is still used. The issue was that a generator
30 contains a frame, and the frame kept a reference to the Python state of the

587 64-bit/32-bit installer for 10.6+. It is no longer necessary
588 to install a third-party version of Tcl/Tk 8.5 to work around the
589 problems in the Apple-supplied Tcl/Tk 8.5 shipped in OS X 10.6
590 and later releases.

Ned Deilyf84b5312013-10-25 00:44:46 -0700592- Issue #19019: Change the OS X installer build script to use CFLAGS instead
593 of OPT for special build options. By setting OPT, some compiler-specific
594 options like -fwrapv were overridden and thus not used, which could result
595 in broken interpreters when building with clang.

1642 In particular, fix extension module build failures when trying to use
1643 32-bit-only installer Pythons on systems with Xcode 4 (currently
1644 OS X 10.8, 10.7, and optionally 10.6).
1645 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1646 * Since Xcode 4 removes ppc support, extension module builds now
1647 check for ppc compiler support and by default remove ppc and
1648 ppc64 archs when they are not available.
1649 * Extension module builds now revert to using system installed
1650 headers and libs (/usr and /System/Library) if the SDK used
1651 to build the interpreter is not installed or has moved.
1652 * Try to avoid building extension modules with deprecated
1653 and problematic Apple llvm-gcc compiler. If original compiler
1654 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002078- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002079 has left two versions of customize_compiler, the original in
2080 distutils.sysconfig and another copy in distutils.ccompiler, with some
2081 parts of distutils calling one and others using the other.
2082 Complete the revert back to only having one in distutils.sysconfig as
2083 is the case in 3.x.
2084
Ned Deily0d0ea482012-02-10 12:59:06 +01002085- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2086 Distutils-based packages with C extension modules may fail because
2087 Apple has removed gcc-4.2, the version used to build python.org
2088 64-bit/32-bit Pythons. If the user does not explicitly override
2089 the default C compiler by setting the CC environment variable,
2090 Distutils will now attempt to compile extension modules with clang
2091 if gcc-4.2 is required but not found. Also as a convenience, if
2092 the user does explicitly set CC, substitute its value as the default
2093 compiler in the Distutils LDSHARED configuration variable for OS X.
2094 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2095 SDK, neither of which are available in Xcode 4. This change does not
2096 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002346- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2347 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2348 interpreter process. This could cause failures in non-Distutils subprocesses
2349 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002350 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002351 deployment target only in the environment of each build subprocess. It is
2352 still possible to globally override the default by setting
2353 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2354 greater or equal to the default value, the value with which the interpreter
2355 was built.

2385 the ticker doesn't have to wind down to zero from the old starting point
2386 before the new interval takes effect. And if the user increases the
2387 interval, it makes sure the new limit takes effect right away rather have an
2388 early task switch before recognizing the new interval.

3369 This prevents user-created self-referencing ordered dictionaries from
3370 becoming permanently uncollectable GC garbage. The downside is that

3830
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003831- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3832 start byte and the continuation byte(s) are now considered invalid, instead
3833 of the number of bytes specified by the start byte.
3834 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3835 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3836 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3837 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003839- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of

3841 arises from the "Overriding __eq__ blocks inheritance ..." warning
3842 when turned into an exception: in this case the exception simply
3843 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003845- Issue #8748: Fix two issues with comparisons between complex and integer
3846 objects. (1) The comparison could incorrectly return True in some cases
3847 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3848 (2) The comparison raised an OverflowError for large integers, leading
3849 to unpredictable exceptions when combining integers and complex objects
3850 in sets or dicts.
3851
Mark Dickinson81336372010-05-30 12:12:25 +00003852- Issue #5211: Implicit coercion for the complex type is now completely
3853 removed. (Coercion for arithmetic operations was already removed in 2.7
3854 alpha 4, but coercion for rich comparisons was accidentally left in.)
3855
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003856- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00004043- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4044 operation raises multiple signals and more than one of those signals is
4045 trapped, the specification determines the order in which the signals should be
4046 handled. In many cases this order wasn't being followed, leading to the wrong
4047 Python exception being raised.

4233 with a non-empty format string. This is an effort to future-proof user
4234 code. If a derived class does not currently implement __format__ but later
4235 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004236 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004237 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004287- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4288 InvalidOperation instead of returning False. (Comparisons involving a quiet
4289 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4290 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004292- Issue #2531: Comparison operations between floats and Decimal instances now
4293 return a result based on the numeric values of the operands; previously they
4294 returned an arbitrary result based on the relative ordering of id(float) and
4295 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004297- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004298 argument `-` which tells it to read files to compile from stdin. Each line is
4299 read on demand and the named file is compiled immediately. (Original patch by
4300 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00004309- Comparisons using one of <, <=, >, >= between a complex instance and a
4310 Fractions instance now raise TypeError instead of returning True/False. This
4311 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4312 <=> complex, and complex <=> complex comparisons.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004411- Issue #8300: When passing a non-integer argument to struct.pack with any
4412 integer format code, struct.pack first attempts to convert the non-integer
4413 using its __index__ method. If that method is non-existent or raises
4414 TypeError it goes on to try the __int__ method, as described below.
4415
Georg Brandlba83f822010-03-14 09:50:54 +00004416- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4417 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4418 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004419 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4420 inconsistent: __int__ was used for some integer codes but not for others, and
4421 the set of integer codes for which it was used differed between native packing
4422 and standard packing.)

4827-----------------
4828
Georg Brandlba83f822010-03-14 09:50:54 +00004829- The ``__complex__()`` method is now looked up on the class of instances to
4830 make it consistent with other special methods.

4834
Mark Dickinson1b34d252010-01-01 17:27:30 +00004835- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004836 DeprecationWarning when passed a float argument where an integer was expected.
4837 These functions and methods now raise TypeError instead. The majority of the
4838 effects of this change are in the extension modules, but some core functions
4839 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4840 and many unicode/str methods.

4852
Georg Brandlba83f822010-03-14 09:50:54 +00004853- Issue #1811: Improve accuracy and cross-platform consistency for true division
4854 of integers: the result of a/b is now correctly rounded for ints a and b (at
4855 least on IEEE 754 platforms), and in particular does not depend on the
4856 internal representation of a long.

4864
Georg Brandlba83f822010-03-14 09:50:54 +00004865 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00005004- Issue #3382: 'F' formatting for float and complex now convert the result to
5005 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5006 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005007
Georg Brandlba83f822010-03-14 09:50:54 +00005008- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5009 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005010
Georg Brandlba83f822010-03-14 09:50:54 +00005011- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5012 1e-100 used to raise OverflowError, but now gives the requested 120
5013 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005021
Georg Brandlba83f822010-03-14 09:50:54 +00005022- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5023 decimal string that's guaranteed to round back to x under correct rounding
5024 (with round-half-to-even rounding mode). Previously it gave a string based on
5025 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5026 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5027 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005028
Georg Brandlba83f822010-03-14 09:50:54 +00005029- Issue #7117: On almost all platforms: float-to-string and string-to-float
5030 conversions within Python are now correctly rounded. Places these conversions
5031 occur include: str for floats and complex numbers; the float and complex
5032 constructors; old-style and new-style numeric formatting; serialization and
5033 deserialization of floats and complex numbers using marshal, pickle and json;
5034 parsing of float and imaginary literals in Python code; Decimal-to-float
5035 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005036
Georg Brandlba83f822010-03-14 09:50:54 +00005037 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5038 providing correctly-rounded strtod and dtoa C functions. This code is
5039 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5040 the C compiler. There may be a small number of platforms on which correct
5041 operation of this code cannot be guaranteed, so the code is not used: notably,
5042 this applies to platforms where the C double format is not IEEE 754 binary64,
5043 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5044 and Python's configure script is unable to determine how to change the FPU
5045 precision. On these platforms conversions use the platform strtod and dtoa,
5046 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005047
Georg Brandlba83f822010-03-14 09:50:54 +00005048- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5049 uses the correctly-rounded string <-> float conversions described above (when
5050 available), and so produces correctly rounded results that will display nicely
5051 under the float repr. There are two related small changes: (1) round now
5052 accepts any class with an ``__index__()`` method for its second argument (but
5053 no longer accepts floats for the second argument), and (2) an excessively
5054 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5055 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00005272- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00005273 untrackable objects are not tracked by the garbage collector. This can reduce
5274 the size of collections and therefore the garbage collection overhead on
5275 long-running programs, depending on their particular use of datatypes.

5282 internal representation of integers, for performance reasons. Base 2**30 is
5283 enabled by default on 64-bit machines. Add --enable-big-digits option to
5284 configure, which overrides the default. Add sys.long_info structseq to
5285 provide information about the internal format.

Brett Cannon6c4cff02009-03-11 04:51:06 +00005298 requirement. Means the DeprecationWarning from Python 2.6 can go away.
5299
Georg Brandlba83f822010-03-14 09:50:54 +00005300- Issue #5247: Improve error message when unknown format codes are used when
5301 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00005302
Georg Brandlba83f822010-03-14 09:50:54 +00005303- Running Python with the -3 option now also warns about classic division for

Benjamin Petersone18ef192009-01-20 14:21:16 +00005315- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
5316
Georg Brandl29c6a282009-04-05 20:23:13 +00005317- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00005318 were suppressing all exceptions. These include list(), filter(), map(),
5319 zip(), and bytearray().
5320
Benjamin Peterson596d3062009-01-19 15:42:23 +00005321- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00005329- Issue #4935: The overflow checking code in the expandtabs() method common to
5330 str, bytes and bytearray could be optimized away by the compiler, letting the
5331 interpreter segfault instead of raising an error.

5347
Georg Brandlba83f822010-03-14 09:50:54 +00005348- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5349 existing .py counterpart, override the co_filename attributes of all code
5350 objects if the original filename is obsolete (which can happen if the file has
5351 been renamed, moved, or if it is accessed through different paths). Patch by

5405
Georg Brandlba83f822010-03-14 09:50:54 +00005406- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5407 file objects with closefd=False. The file descriptor is still kept open but
5408 the file object behaves like a closed file. The ``FileIO`` object also got a

5434 this code path is really executed because I cannot move to such directory on
5435 win2k)

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006839- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6840
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006841- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6842 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6843 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6844 ``printf`` function, whereas PyString_FromFormat has an independent
6845 implementation and uses "%zd" on all platforms for size_t values.
6846 This makes a difference on win64, where ``printf`` needs "%Id" to display
6847 64bit values.
6848
Benjamin Peterson97179b02008-09-09 20:55:01 +00006849- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6850 error.
6851
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006852- Issue #3777: long() applied to a float object now always return a long
6853 object; previously an int would be returned for small values. the __long__
6854 method is allowed to return either an int or a long, but the behaviour of
6855 float objects should not change to respect backward compatibility.
6856
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006857- Issue #3751: str.rpartition would perform a left-partition when called with
6858 a unicode argument.
6859
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006860- Issue #3683: Fix compilation when --without-threads is given.
6861
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006862- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006863 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006864 was correctly parsed but parsing of subsequent arguments failed.
6865
Vinay Sajip35e3b032008-09-01 14:33:59 +00006866- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006867 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6868 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6869 when given a tuple of classes as second argument, were looking up
6870 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6871 type object.
6872
Neal Norwitz18aa3882008-08-24 05:04:52 +00006873- Fix crashes on memory allocation failure found with failmalloc.
6874
6875- Fix memory leaks found with valgrind and update suppressions file.
6876
6877- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6878
6879- Fix problem using wrong name in decimal module reported by pychecker.
6880
Christian Heimes7d4c3172008-08-22 19:47:25 +00006881- Silenced another compiler warning about a used but not defined
6882 function 'stringlib_contains_obj'.
6883
Benjamin Peterson712ee922008-08-24 18:10:20 +00006884- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6885 ``__delslice__``.
6886

6888 library targets in the Makefile.
6889
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006890- Issue #1204: The configure script now tests for additional libraries
6891 that may be required when linking against readline. This fixes issues
6892 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00006942 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6943 for catch_warnings() also led to an improvement in the raising of a
6944 DeprecationWarning related to warnings.warn_explicit().
6945

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007010What's New in Python 2.6 beta 3?
7011================================
7012
Barry Warsaw07a4a382008-08-21 01:15:08 +00007013*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007014
7015Core and Builtins
7016-----------------
7017
Guido van Rossumf8402962008-08-20 15:01:50 +00007018- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7019 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7020 extensions do not automatically benefit from the class attribute
7021 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7022 to their tp_flags field if they care. This is a backwards
7023 compatibility feature; in 3.0, all types will use the cache by
7024 default.
7025
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007026- Keyword arguments can now follow starred arguments. (``f(a, *args,
7027 keyword=23)`` is now valid syntax.)
7028
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007029- ctypes function pointers that are COM methods have a boolean True
7030 value again.
7031
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007032- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7033 by denying s# to parse objects that have a releasebuffer procedure,
7034 and introducing s*.
7035
Georg Brandl1e13ea92008-08-11 09:07:59 +00007036- Issue #3537: Fix an assertion failure when an empty but presized dict
7037 object was stored in the freelist.
7038
Mark Dickinsonb6467572008-08-04 21:30:09 +00007039- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7040 ValueError consistently across platforms.
7041
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007042- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7043 (64bit Unix, for example), unichr() would truncate its argument and return
7044 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7045
Neal Norwitze7d8be82008-07-31 17:17:14 +00007046- Apply security patches from Apple.
7047
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007048- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7049 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7050
Antoine Pitrou92f82162008-07-25 22:22:08 +00007051- Issue #1819: function calls with several named parameters are now on
7052 average 35% faster (as measured by pybench).
7053
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007054- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7055 the python debugger steps into a class statement: the free variables (local
7056 variables defined in an outer scope) would be deleted from the outer scope.
7057
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007058- Issue #2620: Overflow checking when allocating or reallocating memory
7059 was not always being done properly in some python types and extension
7060 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7061 all been updated to perform better checks and places in the code that
7062 would previously leak memory on the error path when such an allocation
7063 failed have been fixed.

7071 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7072
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007073- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7074 version reported by these tools does not necessarily follow the python
7075 version numbering scheme, so the module is less strict when parsing it.
7076
Nick Coghlanf70385a2008-08-18 12:42:46 +00007077- Issue #2235: Added Py3k warnings for types which will become unhashable
7078 under the stricter __hash__ inheritance rules in 3.0. Several types
7079 which did not meet the rules for hash invariants and were already
7080 unhashable in 3.0 have now been explicitly flagged as unhashable in
7081 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7082 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7083
Brett Cannon88f801d2008-08-18 00:46:22 +00007084- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7085 imported into the module but exposed as part of the module's API.
7086

7092
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007093- Issue #3575: Incremental decoder's decode function now takes bytearray
7094 by using 's*' instead of 't#'.
7095
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007096- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007097 fails unicode conversion on 2nd parameter. (windows only)
7098
Georg Brandl222e2082010-08-01 22:27:39 +00007099- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007100 in a redirect.
7101

Brett Cannon721b1452008-08-16 22:00:27 +00007103 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007104
Facundo Batistaeb90b782008-08-16 14:44:07 +00007105- Issue #2776: fixed small issue when handling an URL with double slash
7106 after a 302 response in the case of not going through a proxy.
7107
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007108- Issue #2676: in the email package, content-type parsing was hanging on
7109 pathological input because of quadratic or exponential behaviour of a
7110 regular expression.
7111
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007112- Issue #3476: binary buffered reading through the new "io" library is now

Antoine Pitroude781a42008-08-09 12:43:23 +00007153 asking for a specific length. This problem only affected files opened

7197
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007198- Issue #643841: The language reference now provides more detailed

7211
Georg Brandl3e483f62008-07-16 22:57:41 +00007212- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7213 its methods now allow for items objects that can be converted to
7214 an integer using operator.index().
7215
Mark Dickinson64b7e502008-07-16 09:40:03 +00007216- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7217 produced a ValueError instead of giving the correct float.
7218
Eric Smitha5fa5a22008-07-16 00:11:49 +00007219- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7220 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7221
Mark Dickinson7103aa42008-07-15 19:08:33 +00007222- Issue #3008: the float type has a new instance method 'float.hex'
7223 and a new class method 'float.fromhex' to convert floating-point
7224 numbers to and from hexadecimal strings, respectively.
7225
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007226- Issue #2235: __hash__ is once again inherited by default. To allow
7227 collections.Hashable to remain meaningful in the presence of the
7228 default hash implementation (object.__hash__), it is now possible
7229 to explicit block inheritance of hash by setting __hash__=None at
7230 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7231 level.
7232
Nick Coghlanb028f502008-07-13 14:52:36 +00007233- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7234 the parent module cannot be found while performing an absolute import.
7235 This means that an incorrectly defined __package__ attribute will
7236 now only prevent relative imports in that module rather than causing
7237 all imports from that module to fail.
7238
Nick Coghlan14ff9942008-07-08 14:21:42 +00007239- Issue #2517: Allow unicode messages in Exceptions again by correctly

7249 another thread's dictionary.
7250
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007251- Issue #3004: Minor change to slice.indices(): the start and stop
7252 arguments are now treated identically, making the behaviour easier
7253 to describe and understand. For example, slice(None, -10,
7254 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7255 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7256 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007258- Issue #3219: Calling a function with repeated keyword arguments,
7259 f(a=2, a=23), would not cause a syntax error. This was a regression
7260 from 2.4 caused by the switch to the new compiler.

7299 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007300 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007301 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007317- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Vinay Sajip9828b7e2008-06-17 11:04:02 +00007686- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007687 environment to control the '-arch' flags that are used to build
7688 an extension. This was added for compatibility with Apple's build
7689 of Python.
7690
7691- The bundled OSX-specific copy of libbffi is now in sync with the version
7692 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.

7703
Brett Cannonb61d8012008-05-11 23:39:04 +00007704- ``Lib/lib-old`` is now added to sys.path.
7705
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007706- On MacOS X it is now possible to install the framework in 64-bit
7707 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007708 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007709
7710 This is controlled by the configure argument ``--with-universal-archs``:
7711
7712 - ``--with-universal-archs=all``: install 4-way universal
7713
7714 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7715
7716 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7717
7718 This option should be used in combination with ``--enable-universalsdk=``.
7719
7720 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 +00007769- Issue #1631171: Re-implement the 'warnings' module in C (the
7770 original Python code has been kept as backup). This will allow for
7771 using the 'warning's machinery in such places as the parser where
7772 use of pure Python code is not possible. Both the ``showarning()``
7773 and ``formatwarning()`` gain an optional 'line' argument which is
7774 not called by default for backwards-compatibility reasons. Setting
7775 ``warnings.showwarning()`` to an implementation that lacks support
7776 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007801- The getpass module has been improved on Unix. It now uses /dev/tty
7802 by default and uses stderr instead of stdout. A GetPassWarning is
7803 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007818- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007819 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007839- Issue #2550: The approach used by client/server code for obtaining
7840 ports to listen on in network-oriented tests has been refined in an
7841 effort to facilitate running multiple instances of the entire
7842 regression test suite in parallel without issue.
7843 test_support.bind_port() has been fixed such that it will always
7844 return a unique port -- which wasn't always the case with the
7845 previous implementation, especially if socket options had been set
7846 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7847 new implementation of bind_port() will actually raise an exception
7848 if it is passed an AF_INET/SOCK_STREAM socket with either the
7849 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7850 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7851 the socket it's been passed. This currently only applies to
7852 Windows. This option prevents any other sockets from binding to the
7853 host/port we've bound to, thus removing the possibility of the
7854 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7855 when a second SOCK_STREAM socket binds and accepts to a host/port
7856 that's already been bound by another socket. The optional preferred
7857 port parameter to bind_port() has been removed. Under no
7858 circumstances should tests be hard coding ports!
7859
7860 test_support.find_unused_port() has also been introduced, which will
7861 pass a temporary socket object to bind_port() in order to obtain an
7862 unused port. The temporary socket object is then closed and
7863 deleted, and the port is returned. This method should only be used
7864 for obtaining an unused port in order to pass to an external program
7865 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7866 a parameter to a server-oriented class that doesn't give you direct
7867 access to the underlying socket used.
7868
7869 Finally, test_support.HOST has been introduced, which should be used
7870 for the host argument of any relevant socket calls (i.e. bind and
7871 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007872
7873 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007874 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007875 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7876 test_asynchat and test_socket_ssl.
7877
Georg Brandl3ee81df2008-05-17 18:14:43 +00007878 It is now possible for multiple instances of the regression test
7879 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008158- Added the future_builtins module, which contains hex() and oct().
8159 These are the PEP 3127 version of these functions, designed to be
8160 compatible with the hex() and oct() builtins from Python 3.0. They
8161 differ slightly in their output formats from the existing, unchanged
8162 Python 2.6 builtins. The expected usage of the future_builtins
8163 module is:
8164 from future_builtins import hex, oct
8165
Eric Smith7ef40bf2008-02-20 23:34:22 +00008166- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8167 exponents for exponents with absolute value < 100. Follows C99
8168 standard. This is a change on Windows, which would use 3 digits.
8169 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8170 so that any alterations it does to the resulting string will be
8171 available in stringlib/formatter.h (for float.__format__).
8172
Eric Smith5a3c1352008-02-19 13:21:56 +00008173- Implemented PEP 3101, Advanced String Formatting. This adds a new
8174 builtin format(); a format() method for str and unicode; a
8175 __format__() method to object, str, unicode, int, long, float, and
8176 datetime; the class string.Formatter; and the C API
8177 PyObject_Format().
8178
Georg Brandl3ee81df2008-05-17 18:14:43 +00008179- Fixed several potential crashes, all caused by specially crafted
8180 __del__ methods exploiting objects in temporarily inconsistent
8181 state.

8185 a slot on a registered virtual subclass.

8191 in order to allow pymalloc to free more arenas. Python may give back
8192 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008193
Georg Brandl3ee81df2008-05-17 18:14:43 +00008194- Issue #2045: Fix an infinite recursion triggered when printing a
8195 subclass of collections.defaultdict, if its default_factory is set
8196 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008197
Christian Heimesf75dbef2008-02-08 00:11:31 +00008198- Fixed a minor memory leak in dictobject.c. The content of the free
8199 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00008201- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008202 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008203
Georg Brandl3ee81df2008-05-17 18:14:43 +00008204- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8205 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008206 to compact the internal free lists of pre-allocted ints and floats.
8207
Georg Brandl3ee81df2008-05-17 18:14:43 +00008208- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8209 calls. Python expected the return type int but the fork familie
8210 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008211
Georg Brandl3ee81df2008-05-17 18:14:43 +00008212- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8213 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008214
Georg Brandl3ee81df2008-05-17 18:14:43 +00008215- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8216 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008217
Georg Brandl3ee81df2008-05-17 18:14:43 +00008218- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8219 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00008221- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8222 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008223
Georg Brandl3ee81df2008-05-17 18:14:43 +00008224- Patch #1473257: generator objects gain a gi_code attribute. This is
8225 the same object as the func_code attribute of the function that
8226 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008227
Georg Brandl3ee81df2008-05-17 18:14:43 +00008228- Issue #1920: "while 0" statements were completely removed by the
8229 compiler, even in the presence of an "else" clause, which is
8230 supposed to be run when the condition is false. Now the compiler
8231 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008232
Guido van Rossumeead05f2008-01-24 18:21:02 +00008233- A few crashers fixed: weakref_in_del.py (issue #1377858);
8234 loosing_dict_ref.py (issue #1303614, test67.py);
8235 borrowed_ref_[34].py (not in tracker).
8236
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008237- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008238 suppressed while an extension is loaded by calling SetErrorMode in
8239 dynload_win.c. The error is still reported properly.
8240
Georg Brandl3ee81df2008-05-17 18:14:43 +00008241- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008242 several extension methods and modules do not work without unicode
8243 support.
8244
Georg Brandl26543b12008-01-21 18:36:51 +00008245- Issue #1882: when compiling code from a string, encoding cookies in the
8246 second line of code were not always recognized correctly.
8247
Georg Brandl14404b62008-01-19 19:27:05 +00008248- Issue #1679: "0x" was taken as a valid integer literal.
8249
Georg Brandl6caad7d2008-01-26 14:19:22 +00008250- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008251 added.
8252
Christian Heimesc94e2b52008-01-14 04:13:37 +00008253- sys.float_info / PyFloat_GetInfo: The floating point information
8254 object was converted from a dict to a specialized structseq object.
8255
Georg Brandl3ee81df2008-05-17 18:14:43 +00008256- Patch #1816: Added sys.flags structseq. It exposes the status of
8257 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008258
Georg Brandl3ee81df2008-05-17 18:14:43 +00008259- Objects/structseq.c: Implemented new structseq representation. The
8260 patch makes structseqs (e.g. the return value of os.stat) more
8261 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008262
Georg Brandl3ee81df2008-05-17 18:14:43 +00008263- Patch #1700288: added a type attribute cache that caches method
8264 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008265
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008266- Bug #1776: __import__() no longer accepts filenames on any platform.
8267 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008268
Georg Brandlaed6c662008-01-07 17:25:53 +00008269- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8270
Georg Brandl3ee81df2008-05-17 18:14:43 +00008271- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8272 envvar and sys.dont_write_bytecode attribute. All these can be set
8273 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008274
Georg Brandl3ee81df2008-05-17 18:14:43 +00008275- Improve some exception messages when Windows fails to load an
8276 extension module. Now we get for example '%1 is not a valid Win32
8277 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008278
Georg Brandl3ee81df2008-05-17 18:14:43 +00008279- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008281- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8282 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008283
Christian Heimes0a8143f2007-12-18 23:22:54 +00008284- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008285 and INF. float("nan"), float("inf") and float("-inf") now work on
8286 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008287
Georg Brandl3ee81df2008-05-17 18:14:43 +00008288- Compiler now generates simpler and faster code for dictionary
8289 literals. The oparg for BUILD_MAP now indicates an estimated
8290 dictionary size. There is a new opcode, STORE_MAP, for adding
8291 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008292
Georg Brandl3ee81df2008-05-17 18:14:43 +00008293- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008301- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008302 SystemError.
8303
Nick Coghlanef01d822007-12-03 12:55:17 +00008304- PEP 366: Allow explicit relative imports when executing modules
8305 inside packages with the -m switch via a new module level

Georg Brandl3ee81df2008-05-17 18:14:43 +00008320- Patch #1739468: Directories and zipfiles containing a __main__.py
8321 file can now be directly executed by passing their name to the
8322 interpreter. The directory/zipfile is automatically inserted as the
8323 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008324
Georg Brandl3ee81df2008-05-17 18:14:43 +00008325- Issue #1265: Fix a problem with sys.settrace, if the tracing
8326 function uses a generator expression when at the same time the
8327 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008328
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008329- sets and frozensets now have an isdisjoint() method.
8330
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008331- optimize the performance of builtin.sum().
8332
Neal Norwitz44f326e2007-10-05 05:29:17 +00008333- Fix warnings found by the new version of the Coverity checker.
8334
Georg Brandl21e99f42010-03-07 15:23:59 +00008335- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008336 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8337 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008338
Georg Brandl3ee81df2008-05-17 18:14:43 +00008339- Issue #1686386: Tuple's tp_repr did not take into account the
8340 possibility of having a self-referential tuple, which is possible
8341 from C code. Nor did object's tp_str consider that a type's tp_str
8342 could do something that could lead to an inifinite recursion.
8343 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8344 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008345
Georg Brandl3ee81df2008-05-17 18:14:43 +00008346- Issue #1164: It was possible to trigger deadlock when using the
8347 'print' statement to write to a file since the GIL was not released
8348 as needed. Now PyObject_Print() does the right thing along with
8349 various tp_print implementations of the built-in types and those in
8350 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008351
Georg Brandl3ee81df2008-05-17 18:14:43 +00008352- Issue #1147: Exceptions were directly allowing string exceptions in
8353 their throw() method even though string exceptions no longer
8354 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008355
Georg Brandl3ee81df2008-05-17 18:14:43 +00008356- Issue #1096: Prevent a segfault from getting the repr of a very
8357 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008358
Brett Cannon1e534b52007-09-07 04:18:30 +00008359- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008360 PyObject_Call() never calling back out to Python code to trigger
8361 recursion depth updates/checks. Required the creation of a static
8362 RuntimeError instance in case normalizing an exception put the
8363 recursion check value past its limit. Fixes crashers
8364 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008365
Georg Brandl3ee81df2008-05-17 18:14:43 +00008366- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008379- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008380 __*__ attributes. (Some already existed, e.g., __doc__ and
8381 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008382
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008383- Add -3 option to the interpreter to warn about features that are
8384 deprecated and will be changed/removed in Python 3.0.
8385
Georg Brandl2134e752007-05-21 20:34:16 +00008386- Patch #1686487: you can now pass any mapping after '**' in function
8387 calls.
8388
Collin Winter62903052007-05-18 23:11:24 +00008389- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008390 "except E as target:". This is to provide forwards compatibility
8391 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00008393- Deprecate BaseException.message as per PEP 352.
8394
Georg Brandl3ee81df2008-05-17 18:14:43 +00008395- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008396 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008398- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008399 setting a plain string, ie don't expand to single letter identifiers.
8400
Raymond Hettinger13936692007-04-11 18:40:58 +00008401- Request #1191699: Slices can now be pickled.
8402
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008403- Request #1193128: str.translate() now allows a None argument for
8404 translations that only remove characters without re-mapping the
8405 remaining characters.
8406
Georg Brandl5cb76c12007-03-21 09:00:39 +00008407- Patch #1682205: a TypeError while unpacking an iterable is no longer
8408 masked by a generic one with the message "unpack non-sequence".
8409
Neal Norwitzaa754b72007-03-21 06:39:48 +00008410- Remove unused file Python/fmod.c.
8411
Guido van Rossum143b5642007-03-23 04:58:42 +00008412- Bug #1683368: The object.__init__() and object.__new__() methods are
8413 now stricter in rejecting excess arguments. The only time when
8414 either allows excess arguments is when it is not overridden and the
8415 other one is. For backwards compatibility, when both are
8416 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008417 warning later). Also, type.__init__() insists on the same signature
8418 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008419
Georg Brandl3ee81df2008-05-17 18:14:43 +00008420- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8421 object to complex using its __complex__() method before falling back
8422 to the __float__() method. Therefore, the functions in the cmath
8423 module now can operate on objects that define a __complex__()
8424 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009012 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00009491 time so that opening a database previously created with the DB_DUP
9492 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9493 opens. Specifically: dictionary assignment to a DB object will
9494 replace all values for a given key when the database allows
9495 duplicate values. DB users should use DB.put(k, v) when they want
9496 to store duplicates; not DB[k] = v.

9505 behavior of quoting dots if they are the second character of any
9506 line.
