1420 32-bit-only installer Pythons on systems with Xcode 4 (currently
1421 OS X 10.8, 10.7, and optionally 10.6).
1422 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1423 * Since Xcode 4 removes ppc support, extension module builds now
1424 check for ppc compiler support and by default remove ppc and
1425 ppc64 archs when they are not available.
1426 * Extension module builds now revert to using system installed
1427 headers and libs (/usr and /System/Library) if the SDK used
1428 to build the interpreter is not installed or has moved.
1429 * Try to avoid building extension modules with deprecated
1430 and problematic Apple llvm-gcc compiler. If original compiler
1431 is not available, use clang instead by default.

1781
Mark Dickinsondbbed042011-09-19 16:38:08 +01001782- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1783 int.__pow__. These overflow checks were causing int.__pow__ to produce
1784 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001785 compiler optimizing the check away. Also fix similar overflow checks
1786 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1787 bugs caused test failures with recent versions of Clang.

1799 cleared by the garbage collector. This fixes a segfault when an instance
1800 and its type get caught in a reference cycle, and the instance's
1801 deallocator calls one of the methods on the type (e.g. when subclassing
1802 IOBase). Diagnosis and patch by Davide Rizzo.

Florent Xiclunac2279652012-02-12 14:49:03 +01001855- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001856 has left two versions of customize_compiler, the original in
1857 distutils.sysconfig and another copy in distutils.ccompiler, with some
1858 parts of distutils calling one and others using the other.
1859 Complete the revert back to only having one in distutils.sysconfig as
1860 is the case in 3.x.
1861
Ned Deily0d0ea482012-02-10 12:59:06 +01001862- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1863 Distutils-based packages with C extension modules may fail because
1864 Apple has removed gcc-4.2, the version used to build python.org
1865 64-bit/32-bit Pythons. If the user does not explicitly override
1866 the default C compiler by setting the CC environment variable,
1867 Distutils will now attempt to compile extension modules with clang
1868 if gcc-4.2 is required but not found. Also as a convenience, if
1869 the user does explicitly set CC, substitute its value as the default
1870 compiler in the Distutils LDSHARED configuration variable for OS X.
1871 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1872 SDK, neither of which are available in Xcode 4. This change does not
1873 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002123- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2124 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2125 interpreter process. This could cause failures in non-Distutils subprocesses
2126 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002127 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002128 deployment target only in the environment of each build subprocess. It is
2129 still possible to globally override the default by setting
2130 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2131 greater or equal to the default value, the value with which the interpreter
2132 was built.

2161 updating the check interval, so if the user decreases the check interval,
2162 the ticker doesn't have to wind down to zero from the old starting point
2163 before the new interval takes effect. And if the user increases the
2164 interval, it makes sure the new limit takes effect right away rather have an
2165 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003145- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3146 This prevents user-created self-referencing ordered dictionaries from
3147 becoming permanently uncollectable GC garbage. The downside is that
3148 removing __del__ means that the internal doubly-linked list has to wait for
3149 GC collection rather than freeing memory immediately when the refcnt drops
3150 to zero.

3159 original error is re-raised.

3607
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003608- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3609 start byte and the continuation byte(s) are now considered invalid, instead
3610 of the number of bytes specified by the start byte.
3611 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3612 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3613 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3614 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003622- Issue #8748: Fix two issues with comparisons between complex and integer
3623 objects. (1) The comparison could incorrectly return True in some cases
3624 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3625 (2) The comparison raised an OverflowError for large integers, leading
3626 to unpredictable exceptions when combining integers and complex objects
3627 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003629- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004009- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4010 with a non-empty format string. This is an effort to future-proof user
4011 code. If a derived class does not currently implement __format__ but later
4012 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004013 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004014 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004047- Issue #8257: The Decimal construct now accepts a float instance directly,
4048 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004049

Georg Brandlfee0f442010-05-22 21:26:21 +00004064- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4065 InvalidOperation instead of returning False. (Comparisons involving a quiet
4066 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4067 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004068
Georg Brandlfee0f442010-05-22 21:26:21 +00004069- Issue #2531: Comparison operations between floats and Decimal instances now
4070 return a result based on the numeric values of the operands; previously they
4071 returned an arbitrary result based on the relative ordering of id(float) and
4072 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004074- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004075 argument `-` which tells it to read files to compile from stdin. Each line is
4076 read on demand and the named file is compiled immediately. (Original patch by
4077 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00004086- Comparisons using one of <, <=, >, >= between a complex instance and a
4087 Fractions instance now raise TypeError instead of returning True/False. This
4088 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4089 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004157- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
4158 a base64 transfer-encoded payload *after* decoding it; it no longer does.
4159 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00004188- Issue #8300: When passing a non-integer argument to struct.pack with any
4189 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00004193- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4194 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4195 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004196 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4197 inconsistent: __int__ was used for some integer codes but not for others, and
4198 the set of integer codes for which it was used differed between native packing
4199 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004500 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004501 Also, raise ValueError rather than TypeError when an unknown TIPC address
4502 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004506- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004507 file position when calling `truncate()`. It would previously change the file
4508 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004509 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4510

4512 class used to represent files stored inside an archive. The new
4513 implementation is significantly faster and can be wrapped in a
4514 ``io.BufferedReader`` object for more speedups. It also solves an issue
4515 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004526- Issue #7748: Since unicode values are supported for some metadata options in
4527 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4528 encoded string for them. This ensures that the upload and register commands
4529 send the correct values to PyPI without any error.

4603Core and Builtins
4604-----------------
4605
Georg Brandlba83f822010-03-14 09:50:54 +00004606- The ``__complex__()`` method is now looked up on the class of instances to
4607 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004609- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4610 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4611
Mark Dickinson1b34d252010-01-01 17:27:30 +00004612- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004613 DeprecationWarning when passed a float argument where an integer was expected.
4614 These functions and methods now raise TypeError instead. The majority of the
4615 effects of this change are in the extension modules, but some core functions
4616 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4617 and many unicode/str methods.

4631 of integers: the result of a/b is now correctly rounded for ints a and b (at
4632 least on IEEE 754 platforms), and in particular does not depend on the
4633 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00004640 executables on OSX.
4641
Georg Brandlba83f822010-03-14 09:50:54 +00004642 These executables now work properly with the arch(1) command: ``arch -ppc
4643 python`` will start a universal binary version of python in PPC mode (unlike
4644 previous releases).

4783 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004784

Georg Brandlba83f822010-03-14 09:50:54 +00004799- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4800 decimal string that's guaranteed to round back to x under correct rounding
4801 (with round-half-to-even rounding mode). Previously it gave a string based on
4802 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4803 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4804 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004805
Georg Brandlba83f822010-03-14 09:50:54 +00004806- Issue #7117: On almost all platforms: float-to-string and string-to-float
4807 conversions within Python are now correctly rounded. Places these conversions
4808 occur include: str for floats and complex numbers; the float and complex
4809 constructors; old-style and new-style numeric formatting; serialization and
4810 deserialization of floats and complex numbers using marshal, pickle and json;
4811 parsing of float and imaginary literals in Python code; Decimal-to-float
4812 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004813
Georg Brandlba83f822010-03-14 09:50:54 +00004814 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4815 providing correctly-rounded strtod and dtoa C functions. This code is
4816 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4817 the C compiler. There may be a small number of platforms on which correct
4818 operation of this code cannot be guaranteed, so the code is not used: notably,
4819 this applies to platforms where the C double format is not IEEE 754 binary64,
4820 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4821 and Python's configure script is unable to determine how to change the FPU
4822 precision. On these platforms conversions use the platform strtod and dtoa,
4823 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004825- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4826 uses the correctly-rounded string <-> float conversions described above (when
4827 available), and so produces correctly rounded results that will display nicely
4828 under the float repr. There are two related small changes: (1) round now
4829 accepts any class with an ``__index__()`` method for its second argument (but
4830 no longer accepts floats for the second argument), and (2) an excessively
4831 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4832 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004979- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4980 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4981 but with at least one decimal point and with a default precision
4982 of 12. Previously, the behavior the same but with a default precision of 6.
4983 This more closely matches ``str()``, and reduces surprises when adding
4984 alignment flags to the empty presentation type. This also affects the new
4985 complex.__format__ in the same way.
4986

Georg Brandlba83f822010-03-14 09:50:54 +00005183- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5184 file objects with closefd=False. The file descriptor is still kept open but
5185 the file object behaves like a closed file. The ``FileIO`` object also got a
5186 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00005209- On windows, ``os.chdir()`` given unicode was not working if

5211 this code path is really executed because I cannot move to such directory on

5216 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00005237- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5238 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5239 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5240 of using the replace error handler in PyUnicode_DecodeUTF8().
5241
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005242- Issue #3739: The unicode-internal encoder now reports the number of characters

5244
Georg Brandlba83f822010-03-14 09:50:54 +00005245- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5247 gives improved memory leak detection when running under Valgrind, while taking
5248 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006616- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6617
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006618- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6619 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6620 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6621 ``printf`` function, whereas PyString_FromFormat has an independent
6622 implementation and uses "%zd" on all platforms for size_t values.
6623 This makes a difference on win64, where ``printf`` needs "%Id" to display
6624 64bit values.
6625
Benjamin Peterson97179b02008-09-09 20:55:01 +00006626- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6630 object; previously an int would be returned for small values. the __long__
6631 method is allowed to return either an int or a long, but the behaviour of
6632 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006634- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00006640 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006641 was correctly parsed but parsing of subsequent arguments failed.
6642
Vinay Sajip35e3b032008-09-01 14:33:59 +00006643- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006644 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6645 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6646 when given a tuple of classes as second argument, were looking up
6647 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6648 type object.
6649

6793-----------------
6794
Guido van Rossumf8402962008-08-20 15:01:50 +00006795- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6796 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6797 extensions do not automatically benefit from the class attribute
6798 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6799 to their tp_flags field if they care. This is a backwards
6800 compatibility feature; in 3.0, all types will use the cache by
6801 default.
6802
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006803- Keyword arguments can now follow starred arguments. (``f(a, *args,
6804 keyword=23)`` is now valid syntax.)
6805
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006806- ctypes function pointers that are COM methods have a boolean True
6807 value again.
6808
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006809- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6810 by denying s# to parse objects that have a releasebuffer procedure,
6811 and introducing s*.
6812
Georg Brandl1e13ea92008-08-11 09:07:59 +00006813- Issue #3537: Fix an assertion failure when an empty but presized dict
6814 object was stored in the freelist.
6815
Mark Dickinsonb6467572008-08-04 21:30:09 +00006816- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6817 ValueError consistently across platforms.
6818
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006819- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6820 (64bit Unix, for example), unichr() would truncate its argument and return
6821 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6822
Neal Norwitze7d8be82008-07-31 17:17:14 +00006823- Apply security patches from Apple.
6824
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006825- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

6827
Antoine Pitrou92f82162008-07-25 22:22:08 +00006828- Issue #1819: function calls with several named parameters are now on
6829 average 35% faster (as measured by pybench).
6830
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006831- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6832 the python debugger steps into a class statement: the free variables (local
6833 variables defined in an outer scope) would be deleted from the outer scope.
6834
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006835- Issue #2620: Overflow checking when allocating or reallocating memory
6836 was not always being done properly in some python types and extension
6837 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6838 all been updated to perform better checks and places in the code that
6839 would previously leak memory on the error path when such an allocation

6846
Benjamin Petersone977ad42008-08-20 01:42:01 +00006847- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6848 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6849
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006850- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6851 version reported by these tools does not necessarily follow the python
6852 version numbering scheme, so the module is less strict when parsing it.
6853
Nick Coghlanf70385a2008-08-18 12:42:46 +00006854- Issue #2235: Added Py3k warnings for types which will become unhashable
6855 under the stricter __hash__ inheritance rules in 3.0. Several types
6856 which did not meet the rules for hash invariants and were already
6857 unhashable in 3.0 have now been explicitly flagged as unhashable in
6858 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6859 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6860
Brett Cannon88f801d2008-08-18 00:46:22 +00006861- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6862 imported into the module but exposed as part of the module's API.
6863
Brett Cannon7b96f072008-08-18 00:41:11 +00006864- Remove an unneeded import of abc.ABCMeta from 'inspect'.

6869
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006870- Issue #3575: Incremental decoder's decode function now takes bytearray
6871 by using 's*' instead of 't#'.
6872
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006873- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006874 fails unicode conversion on 2nd parameter. (windows only)
6875
Georg Brandl222e2082010-08-01 22:27:39 +00006876- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006877 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +00006879- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006880 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006881
Facundo Batistaeb90b782008-08-16 14:44:07 +00006882- Issue #2776: fixed small issue when handling an URL with double slash
6883 after a 302 response in the case of not going through a proxy.
6884
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006885- Issue #2676: in the email package, content-type parsing was hanging on
6886 pathological input because of quadratic or exponential behaviour of a
6887 regular expression.
6888
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006889- Issue #3476: binary buffered reading through the new "io" library is now
6890 thread-safe.
6891
Brett Cannonbf3157b2008-08-14 05:00:03 +00006892- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6893 since mimetools itself is deprecated. Because modules are cached, all
6894 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6895
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006896- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00006898- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6899 menu entries were not deleted.
6900
Brett Cannon83e81842008-08-09 23:30:55 +00006901- Copied the implementation of reduce() to _functools.reduce() to have a
6902 version that did not raise a DeprecationWarning under -3.
6903
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006904- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6905 a MemoryError rather than silently stop the iteration.
6906
Guido van Rossum59ce9012008-08-09 14:55:34 +00006907- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6908 to _sre.compile() will now be rejected. This should not affect anybody
6909 since the re.compile() function never generates invalid re-bytecode.
6910
Skip Montanaroa032bf42008-08-08 22:52:51 +00006911- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6912 upon first access it can be automatically initialized from the csv file if
6913 it wasn't initialized during instantiation.
6914
Brett Cannon3aa2a492008-08-06 22:28:09 +00006915- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6916 the reload() built-in has been removed.
6917
Brett Cannon7e30b672008-08-04 21:52:25 +00006918- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006919 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6927 raised an AttributeError.
6928

Antoine Pitroude781a42008-08-09 12:43:23 +00006930 asking for a specific length. This problem only affected files opened
6931 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006932

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006956- Issue #3394: zipfile.writestr sets external attributes when passed a
6957 file name rather than a ZipInfo instance, so files are extracted with
6958 mode 0600 rather than 000 under Unix.
6959
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006960- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6961 argument in python 2.5, this broke code that subclassed Popen to include its
6962 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6973 interaction with the tp_hash slot (added in 2.6b2) are now documented
6974
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006975- Issue #643841: The language reference now provides more detailed
6976 coverage of the lookup process for special methods. The disclaimers
6977 regarding lack of coverage of new-style classes have also been
6978 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006986Core and Builtins
6987-----------------
6988
Georg Brandl3e483f62008-07-16 22:57:41 +00006989- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6990 its methods now allow for items objects that can be converted to
6991 an integer using operator.index().
6992
Mark Dickinson64b7e502008-07-16 09:40:03 +00006993- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6994 produced a ValueError instead of giving the correct float.
6995
Eric Smitha5fa5a22008-07-16 00:11:49 +00006996- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6997 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6998
Mark Dickinson7103aa42008-07-15 19:08:33 +00006999- Issue #3008: the float type has a new instance method 'float.hex'
7000 and a new class method 'float.fromhex' to convert floating-point
7001 numbers to and from hexadecimal strings, respectively.
7002
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007003- Issue #2235: __hash__ is once again inherited by default. To allow
7004 collections.Hashable to remain meaningful in the presence of the
7005 default hash implementation (object.__hash__), it is now possible
7006 to explicit block inheritance of hash by setting __hash__=None at
7007 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7008 level.
7009
Nick Coghlanb028f502008-07-13 14:52:36 +00007010- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7011 the parent module cannot be found while performing an absolute import.
7012 This means that an incorrectly defined __package__ attribute will
7013 now only prevent relative imports in that module rather than causing
7014 all imports from that module to fail.
7015
Nick Coghlan14ff9942008-07-08 14:21:42 +00007016- Issue #2517: Allow unicode messages in Exceptions again by correctly
7017 bypassing the instance dictionary when looking up __unicode__ on
7018 new-style classes.
7019
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007020- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7021 set to a custom object whose write() method happens to install
7022 another file in sys.stdout.
7023
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007024- Issue #3088: Corrected a race condition in classes derived from
7025 threading.local: the first member set by a thread could be saved in
7026 another thread's dictionary.
7027
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007028- Issue #3004: Minor change to slice.indices(): the start and stop
7029 arguments are now treated identically, making the behaviour easier
7030 to describe and understand. For example, slice(None, -10,
7031 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7032 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7033 10, -1).
7034
Georg Brandl278fc502008-07-19 12:46:12 +00007035- Issue #3219: Calling a function with repeated keyword arguments,
7036 f(a=2, a=23), would not cause a syntax error. This was a regression
7037 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007038
Georg Brandl278fc502008-07-19 12:46:12 +00007039- Issue #2862: Make int and float freelist management consistent with
7040 other freelists. Changes their CompactFreeList apis into
7041 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00007046- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7047 api functions without holding the GIL, which could lead to a fatal
7048 error when they failed.
7049
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007050- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00007058- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7059 ForkingPickler.register() to resolve conflict with ctypes.

Vinay Sajip51e65192008-07-18 09:01:10 +00007061- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00007063- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7064 a valid dlerror() message.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007075- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7076 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007077 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007078 content-length. The problem had been corrected in the 2.4 branch, but never
7079 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007094- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7096
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007097- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

7482
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007483- On MacOS X it is now possible to install the framework in 64-bit
7484 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007485 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007486
7487 This is controlled by the configure argument ``--with-universal-archs``:
7488
7489 - ``--with-universal-archs=all``: install 4-way universal
7490
7491 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7492
7493 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7494
7495 This option should be used in combination with ``--enable-universalsdk=``.
7496
7497 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 +00007546- Issue #1631171: Re-implement the 'warnings' module in C (the
7547 original Python code has been kept as backup). This will allow for
7548 using the 'warning's machinery in such places as the parser where
7549 use of pure Python code is not possible. Both the ``showarning()``
7550 and ``formatwarning()`` gain an optional 'line' argument which is
7551 not called by default for backwards-compatibility reasons. Setting
7552 ``warnings.showwarning()`` to an implementation that lacks support
7553 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007616- Issue #2550: The approach used by client/server code for obtaining
7617 ports to listen on in network-oriented tests has been refined in an
7618 effort to facilitate running multiple instances of the entire
7619 regression test suite in parallel without issue.
7620 test_support.bind_port() has been fixed such that it will always
7621 return a unique port -- which wasn't always the case with the
7622 previous implementation, especially if socket options had been set
7623 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7624 new implementation of bind_port() will actually raise an exception
7625 if it is passed an AF_INET/SOCK_STREAM socket with either the
7626 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7627 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7628 the socket it's been passed. This currently only applies to
7629 Windows. This option prevents any other sockets from binding to the
7630 host/port we've bound to, thus removing the possibility of the
7631 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7632 when a second SOCK_STREAM socket binds and accepts to a host/port
7633 that's already been bound by another socket. The optional preferred
7634 port parameter to bind_port() has been removed. Under no
7635 circumstances should tests be hard coding ports!
7636
7637 test_support.find_unused_port() has also been introduced, which will
7638 pass a temporary socket object to bind_port() in order to obtain an
7639 unused port. The temporary socket object is then closed and
7640 deleted, and the port is returned. This method should only be used
7641 for obtaining an unused port in order to pass to an external program
7642 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7643 a parameter to a server-oriented class that doesn't give you direct
7644 access to the underlying socket used.
7645
7646 Finally, test_support.HOST has been introduced, which should be used
7647 for the host argument of any relevant socket calls (i.e. bind and
7648 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007649
7650 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007651 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007652 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7653 test_asynchat and test_socket_ssl.
7654
Georg Brandl3ee81df2008-05-17 18:14:43 +00007655 It is now possible for multiple instances of the regression test
7656 suite to run in parallel without issue.

Christian Heimes5224d282008-02-23 15:01:05 +00007931
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007932- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007933 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007934
Eric Smitha73fbe72008-02-23 03:09:44 +00007935- Added the future_builtins module, which contains hex() and oct().
7936 These are the PEP 3127 version of these functions, designed to be
7937 compatible with the hex() and oct() builtins from Python 3.0. They
7938 differ slightly in their output formats from the existing, unchanged
7939 Python 2.6 builtins. The expected usage of the future_builtins
7940 module is:
7941 from future_builtins import hex, oct
7942
Eric Smith7ef40bf2008-02-20 23:34:22 +00007943- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7944 exponents for exponents with absolute value < 100. Follows C99
7945 standard. This is a change on Windows, which would use 3 digits.
7946 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7947 so that any alterations it does to the resulting string will be
7948 available in stringlib/formatter.h (for float.__format__).
7949
Eric Smith5a3c1352008-02-19 13:21:56 +00007950- Implemented PEP 3101, Advanced String Formatting. This adds a new
7951 builtin format(); a format() method for str and unicode; a
7952 __format__() method to object, str, unicode, int, long, float, and
7953 datetime; the class string.Formatter; and the C API
7954 PyObject_Format().
7955
Georg Brandl3ee81df2008-05-17 18:14:43 +00007956- Fixed several potential crashes, all caused by specially crafted
7957 __del__ methods exploiting objects in temporarily inconsistent
7958 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007959
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007960- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007961 prevent a possible crash: an Abstract Base Class would try to access
7962 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007963
Georg Brandl3ee81df2008-05-17 18:14:43 +00007964- Fixed repr() and str() of complex numbers with infinity or nan as
7965 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007966
Georg Brandl3ee81df2008-05-17 18:14:43 +00007967- Clear all free lists during a gc.collect() of the highest generation
7968 in order to allow pymalloc to free more arenas. Python may give back
7969 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007970
Georg Brandl3ee81df2008-05-17 18:14:43 +00007971- Issue #2045: Fix an infinite recursion triggered when printing a
7972 subclass of collections.defaultdict, if its default_factory is set
7973 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007974
Christian Heimesf75dbef2008-02-08 00:11:31 +00007975- Fixed a minor memory leak in dictobject.c. The content of the free
7976 list was not freed on interpreter shutdown.
7977
Georg Brandl21e99f42010-03-07 15:23:59 +00007978- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007979 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007980
Georg Brandl3ee81df2008-05-17 18:14:43 +00007981- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7982 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007983 to compact the internal free lists of pre-allocted ints and floats.
7984
Georg Brandl3ee81df2008-05-17 18:14:43 +00007985- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7986 calls. Python expected the return type int but the fork familie
7987 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007988
Georg Brandl3ee81df2008-05-17 18:14:43 +00007989- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7990 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007991
Georg Brandl3ee81df2008-05-17 18:14:43 +00007992- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7993 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007994
Georg Brandl3ee81df2008-05-17 18:14:43 +00007995- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7996 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007997
Georg Brandl3ee81df2008-05-17 18:14:43 +00007998- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7999 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008000
Georg Brandl3ee81df2008-05-17 18:14:43 +00008001- Patch #1473257: generator objects gain a gi_code attribute. This is
8002 the same object as the func_code attribute of the function that
8003 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008004
Georg Brandl3ee81df2008-05-17 18:14:43 +00008005- Issue #1920: "while 0" statements were completely removed by the
8006 compiler, even in the presence of an "else" clause, which is
8007 supposed to be run when the condition is false. Now the compiler
8008 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008009
Guido van Rossumeead05f2008-01-24 18:21:02 +00008010- A few crashers fixed: weakref_in_del.py (issue #1377858);
8011 loosing_dict_ref.py (issue #1303614, test67.py);
8012 borrowed_ref_[34].py (not in tracker).
8013
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008014- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008015 suppressed while an extension is loaded by calling SetErrorMode in
8016 dynload_win.c. The error is still reported properly.
8017
Georg Brandl3ee81df2008-05-17 18:14:43 +00008018- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008019 several extension methods and modules do not work without unicode
8020 support.
8021
Georg Brandl26543b12008-01-21 18:36:51 +00008022- Issue #1882: when compiling code from a string, encoding cookies in the
8023 second line of code were not always recognized correctly.
8024
Georg Brandl14404b62008-01-19 19:27:05 +00008025- Issue #1679: "0x" was taken as a valid integer literal.
8026
Georg Brandl6caad7d2008-01-26 14:19:22 +00008027- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008028 added.
8029
Christian Heimesc94e2b52008-01-14 04:13:37 +00008030- sys.float_info / PyFloat_GetInfo: The floating point information
8031 object was converted from a dict to a specialized structseq object.
8032
Georg Brandl3ee81df2008-05-17 18:14:43 +00008033- Patch #1816: Added sys.flags structseq. It exposes the status of
8034 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008035
Georg Brandl3ee81df2008-05-17 18:14:43 +00008036- Objects/structseq.c: Implemented new structseq representation. The
8037 patch makes structseqs (e.g. the return value of os.stat) more
8038 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008039
Georg Brandl3ee81df2008-05-17 18:14:43 +00008040- Patch #1700288: added a type attribute cache that caches method
8041 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008042
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008043- Bug #1776: __import__() no longer accepts filenames on any platform.
8044 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008045
Georg Brandlaed6c662008-01-07 17:25:53 +00008046- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8047
Georg Brandl3ee81df2008-05-17 18:14:43 +00008048- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8049 envvar and sys.dont_write_bytecode attribute. All these can be set
8050 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008051
Georg Brandl3ee81df2008-05-17 18:14:43 +00008052- Improve some exception messages when Windows fails to load an
8053 extension module. Now we get for example '%1 is not a valid Win32
8054 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008055
Georg Brandl3ee81df2008-05-17 18:14:43 +00008056- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008058- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8059 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008060
Christian Heimes0a8143f2007-12-18 23:22:54 +00008061- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008062 and INF. float("nan"), float("inf") and float("-inf") now work on
8063 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008064
Georg Brandl3ee81df2008-05-17 18:14:43 +00008065- Compiler now generates simpler and faster code for dictionary
8066 literals. The oparg for BUILD_MAP now indicates an estimated
8067 dictionary size. There is a new opcode, STORE_MAP, for adding
8068 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008069
Georg Brandl3ee81df2008-05-17 18:14:43 +00008070- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008075- Issue #1538: Avoid copying string in split/rsplit if the split char
8076 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008077
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008078- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008079 SystemError.
8080
Nick Coghlanef01d822007-12-03 12:55:17 +00008081- PEP 366: Allow explicit relative imports when executing modules

8083 __package__ attribute.
8084
Georg Brandl3ee81df2008-05-17 18:14:43 +00008085- Issue #1402: Fix a crash on exit, when another thread is still
8086 running, and if the deallocation of its frames somehow calls the
8087 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008088

8098 file can now be directly executed by passing their name to the
8099 interpreter. The directory/zipfile is automatically inserted as the
8100 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008101
Georg Brandl3ee81df2008-05-17 18:14:43 +00008102- Issue #1265: Fix a problem with sys.settrace, if the tracing
8103 function uses a generator expression when at the same time the
8104 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008105
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008106- sets and frozensets now have an isdisjoint() method.
8107
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008108- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00008110- Fix warnings found by the new version of the Coverity checker.
8111
Georg Brandl21e99f42010-03-07 15:23:59 +00008112- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008113 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8114 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008115
Georg Brandl3ee81df2008-05-17 18:14:43 +00008116- Issue #1686386: Tuple's tp_repr did not take into account the
8117 possibility of having a self-referential tuple, which is possible
8118 from C code. Nor did object's tp_str consider that a type's tp_str
8119 could do something that could lead to an inifinite recursion.
8120 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8121 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008122
Georg Brandl3ee81df2008-05-17 18:14:43 +00008123- Issue #1164: It was possible to trigger deadlock when using the
8124 'print' statement to write to a file since the GIL was not released
8125 as needed. Now PyObject_Print() does the right thing along with
8126 various tp_print implementations of the built-in types and those in
8127 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008128
Georg Brandl3ee81df2008-05-17 18:14:43 +00008129- Issue #1147: Exceptions were directly allowing string exceptions in
8130 their throw() method even though string exceptions no longer
8131 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008132

Brett Cannon1e534b52007-09-07 04:18:30 +00008136- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008137 PyObject_Call() never calling back out to Python code to trigger
8138 recursion depth updates/checks. Required the creation of a static
8139 RuntimeError instance in case normalizing an exception put the
8140 recursion check value past its limit. Fixes crashers
8141 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008142

Neal Norwitz0ac60192007-05-27 04:08:54 +00008156- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008157 __*__ attributes. (Some already existed, e.g., __doc__ and
8158 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008159
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008160- Add -3 option to the interpreter to warn about features that are
8161 deprecated and will be changed/removed in Python 3.0.
8162
Georg Brandl2134e752007-05-21 20:34:16 +00008163- Patch #1686487: you can now pass any mapping after '**' in function
8164 calls.
8165
Collin Winter62903052007-05-18 23:11:24 +00008166- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008167 "except E as target:". This is to provide forwards compatibility
8168 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008169
Brett Cannon229cee22007-05-05 01:34:02 +00008170- Deprecate BaseException.message as per PEP 352.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008172- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008173 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008175- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008176 setting a plain string, ie don't expand to single letter identifiers.

Raymond Hettinger13936692007-04-11 18:40:58 +00008178- Request #1191699: Slices can now be pickled.
8179
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008180- Request #1193128: str.translate() now allows a None argument for
8181 translations that only remove characters without re-mapping the
8182 remaining characters.
8183
Georg Brandl5cb76c12007-03-21 09:00:39 +00008184- Patch #1682205: a TypeError while unpacking an iterable is no longer
8185 masked by a generic one with the message "unpack non-sequence".

Guido van Rossum143b5642007-03-23 04:58:42 +00008189- Bug #1683368: The object.__init__() and object.__new__() methods are
8190 now stricter in rejecting excess arguments. The only time when
8191 either allows excess arguments is when it is not overridden and the
8192 other one is. For backwards compatibility, when both are
8193 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008194 warning later). Also, type.__init__() insists on the same signature
8195 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008197- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8198 object to complex using its __complex__() method before falling back
8199 to the __float__() method. Therefore, the functions in the cmath
8200 module now can operate on objects that define a __complex__()
8201 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008219- Bug #1678647: write a newline after printing an exception in any
8220 case, even when converting the value to a string failed.
8221
Georg Brandl871f1bc2007-03-12 13:17:36 +00008222- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008223 its argument, if it exists. If not, it will work like before. This
8224 allows customizing the output of dir() in the presence of a
8225 __getattr__().

8234 parthensized forms. This means complex(repr(x)) now works instead of
8235 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008236
Georg Brandlaa2321b2007-03-07 00:40:28 +00008237- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008238 makes the filenames the warning module prints much more sensible
8239 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008240

Georg Brandl0fca97a2007-03-05 22:28:08 +00008252- Patch #1674228: when assigning a slice (old-style), check for the
8253 sq_ass_slice instead of the sq_slice slot.
8254
Georg Brandl3ee81df2008-05-17 18:14:43 +00008255- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00008307- Bug #1545497: when given an explicit base, int() did ignore NULs
8308 embedded in the string to convert.
8309
Georg Brandl846f73a2006-10-08 07:11:54 +00008310- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008340- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Neal Norwitzdac090d2006-09-05 03:53:08 +00008357- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008358 generator expressions (x for x, in ... ) works again. Fixing this
8359 problem required changing the .pyc magic number. This means that
8360 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008789 AttributeError instead of an IOError when the server's response
8790 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008824 are set for invalid interpolation sequences that would lead to
8825 errors on reading back those values.

8881 TestCase and TestSuite subclasses (not instances) are no longer
8882 accepted in TestSuite.addTest(). This should cause no
8883 incompatibility since it never made sense with ordinary subclasses
8884 -- the failure just occurred later, with a more cumbersome
8885 exception.

9158 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00009159
Georg Brandl3ee81df2008-05-17 18:14:43 +00009160- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9161 with RFC 3207 and forgets any knowledge obtained from the server not
9162 obtained from the TLS negotiation itself. Patch contributed by Bill
9163 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009164
Georg Brandl3ee81df2008-05-17 18:14:43 +00009165- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009166 that the SMTP.starttls() caller no longer needs to call ehlo()
9167 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009168 does not claim to support starttls. Adds the
9169 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9170 Fenner.

9250 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9251 silently miscode subclasses of those types. Now, it raises a
9252 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009253

Georg Brandl3ee81df2008-05-17 18:14:43 +00009268 time so that opening a database previously created with the DB_DUP
9269 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9270 opens. Specifically: dictionary assignment to a DB object will
9271 replace all values for a given key when the database allows
9272 duplicate values. DB users should use DB.put(k, v) when they want
9273 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009274

9280 characters with ASCII value less than 32. Also, it correctly quotes
9281 dots only if they occur on a single line, as opposed to the previous
9282 behavior of quoting dots if they are the second character of any
9283 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009284

Georg Brandl3ee81df2008-05-17 18:14:43 +00009692- Removed the macfs module. It had been deprecated since Python 2.5.
9693 This lead to the deprecation of macostools.touched() as it relied
9694 solely on macfs and was a no-op under OS X.
