Ned Deily18fae3f2013-01-31 01:24:55 -08001250- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1251 In particular, fix extension module build failures when trying to use
1252 32-bit-only installer Pythons on systems with Xcode 4 (currently
1253 OS X 10.8, 10.7, and optionally 10.6).
1254 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1255 * Since Xcode 4 removes ppc support, extension module builds now
1256 check for ppc compiler support and by default remove ppc and
1257 ppc64 archs when they are not available.
1258 * Extension module builds now revert to using system installed
1259 headers and libs (/usr and /System/Library) if the SDK used
1260 to build the interpreter is not installed or has moved.
1261 * Try to avoid building extension modules with deprecated
1262 and problematic Apple llvm-gcc compiler. If original compiler
1263 is not available, use clang instead by default.

1615 int.__pow__. These overflow checks were causing int.__pow__ to produce
1616 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001617 compiler optimizing the check away. Also fix similar overflow checks
1618 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

1631 cleared by the garbage collector. This fixes a segfault when an instance
1632 and its type get caught in a reference cycle, and the instance's

Ned Deilyc47a4592012-02-11 20:40:24 +01001688 has left two versions of customize_compiler, the original in
1689 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001694- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1695 Distutils-based packages with C extension modules may fail because
1696 Apple has removed gcc-4.2, the version used to build python.org
1697 64-bit/32-bit Pythons. If the user does not explicitly override
1698 the default C compiler by setting the CC environment variable,
1699 Distutils will now attempt to compile extension modules with clang
1700 if gcc-4.2 is required but not found. Also as a convenience, if
1701 the user does explicitly set CC, substitute its value as the default
1702 compiler in the Distutils LDSHARED configuration variable for OS X.
1703 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1704 SDK, neither of which are available in Xcode 4. This change does not
1705 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001955- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1956 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1957 interpreter process. This could cause failures in non-Distutils subprocesses
1958 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001959 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001960 deployment target only in the environment of each build subprocess. It is
1961 still possible to globally override the default by setting
1962 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1963 greater or equal to the default value, the value with which the interpreter
1964 was built.

1994 the ticker doesn't have to wind down to zero from the old starting point
1995 before the new interval takes effect. And if the user increases the
1996 interval, it makes sure the new limit takes effect right away rather have an
1997 early task switch before recognizing the new interval.

2961 handles non-blocking readinto() returning None correctly.
2962

2964 SSLSocket.sendto() to match the corresponding socket methods. Also,
2965 fix various SSLSocket methods to raise socket.error rather than an
2966 unhelpful TypeError when called on an unconnected socket. Original patch
2967 by Andrew Bennetts.
2968
Raymond Hettinger74f869e2010-09-13 22:14:36 +00002969- Issue #9826: OrderedDict.__repr__ can now handle self-referential

2976
Raymond Hettinger20397532010-09-12 02:11:45 +00002977- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2978 This prevents user-created self-referencing ordered dictionaries from
2979 becoming permanently uncollectable GC garbage. The downside is that
2980 removing __del__ means that the internal doubly-linked list has to wait for
2981 GC collection rather than freeing memory immediately when the refcnt drops
2982 to zero.
2983
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002984- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00002985 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002986 value.
2987
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002988- Issue #9792: In case of connection failure, socket.create_connection()
2989 would swallow the exception and raise a new one, making it impossible
2990 to fetch the original errno, or to filter timeout errors. Now the
2991 original error is re-raised.
2992
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002993- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2994 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2995 be updated back after the system call. Original patch by Brian Brazil.
2996
Antoine Pitroudca9de92010-09-04 17:52:26 +00002997- Issue #1100562: Fix deep-copying of objects derived from the list and
2998 dict types. Patch by Michele Orrù and Björn Lindqvist.

3001 ConfigParser.write.
3002
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003003- Issue #808164: Fixed socket.close to avoid references to globals, to
3004 avoid issues when socket.close is called from a __del__ method.
3005
Terry Reedyd2d2ae92010-11-11 23:22:19 +00003006- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
3007 can be set to False to turn off the previously undocumented 'popularity'
3008 heuristic. Patch by Terry Reedy and Eli Bendersky
3009
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003010- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3011 falling into recursion.
3012
R. David Murray7c4bf552010-08-25 01:45:57 +00003013- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3014 character years even if the message contains RFC822 two character years.
3015
Daniel Stutzbach91287322010-08-24 21:09:30 +00003016- Issue #8750: Fixed MutableSet's methods to correctly handle
3017 reflexive operations, namely x -= x and x ^= x.

3028 module now correctly return a set. (Patch by Eli Bendersky.)
3029
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003030- Issue #9617: Signals received during a low-level write operation aren't
3031 ignored by the buffered IO layer anymore.
3032
Benjamin Peterson52c36052010-08-21 03:03:22 +00003033- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3034 are not held onto after they are deleted elsewhere.
3035
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003036- Issue #9626: the view methods for collections.OrderedDict() were returning

3047
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003048- Issue #9550: a BufferedReader could issue an additional read when the
3049 original read request had been satisfied, which could block indefinitely
3050 when the underlying raw IO channel was e.g. a socket. Report and original
3051 patch by Jason V. Miller.
3052
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003053- Issue #9551: Don't raise TypeError when setting the value to None for

3072 This is how it is supposed to work, wget and curl do the same. Previous
3073 behavior was wrong.

3081 the option character for the added 'h/help' option if prefix_chars
3082 does not contain a '-', instead of raising an error.
3083

3444 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

3457 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003802 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3803 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3804 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3825-----------------
3826
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003827- Issue #7301: Add environment variable $PYTHONWARNINGS.
3828
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003829- Issue #8329: Don't return the same lists from select.select when no fds are
3830 changed.
3831
Georg Brandlfee0f442010-05-22 21:26:21 +00003832- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003833 on 64-bit machines. The shift count for either left or right shift is
3834 permitted to be up to sys.maxsize.
3835
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003836- Ensure that tokenization of identifiers is not affected by locale.

3841
Georg Brandlfee0f442010-05-22 21:26:21 +00003842- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3843 with a non-empty format string. This is an effort to future-proof user
3844 code. If a derived class does not currently implement __format__ but later
3845 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003846 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003847 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003848
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003849- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00003862- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003863 (SIGINT). If an error occurs while importing the site module, the error is

3879
Georg Brandlfee0f442010-05-22 21:26:21 +00003880- Issue #8257: The Decimal construct now accepts a float instance directly,
3881 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003882
3883 >>> Decimal(1.1)
3884 Decimal('1.100000000000000088817841970012523233890533447265625')
3885
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003886- collections.Counter() now supports a subtract() method.
3887
Georg Brandlfee0f442010-05-22 21:26:21 +00003888- The functools module now has a total_ordering() class decorator to simplify
3889 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003897- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3898 InvalidOperation instead of returning False. (Comparisons involving a quiet
3899 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3900 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003901
Georg Brandlfee0f442010-05-22 21:26:21 +00003902- Issue #2531: Comparison operations between floats and Decimal instances now
3903 return a result based on the numeric values of the operands; previously they
3904 returned an arbitrary result based on the relative ordering of id(float) and
3905 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003906
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003907- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003908 argument `-` which tells it to read files to compile from stdin. Each line is
3909 read on demand and the named file is compiled immediately. (Original patch by
3910 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00003915- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3916 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003917 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003918
Georg Brandlfee0f442010-05-22 21:26:21 +00003919- Comparisons using one of <, <=, >, >= between a complex instance and a
3920 Fractions instance now raise TypeError instead of returning True/False. This
3921 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3922 <=> complex, and complex <=> complex comparisons.

4031 the set of integer codes for which it was used differed between native packing
4032 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004241- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00004242 is run with the -OO flag. Tests requiring docstrings are skipped.
4243
Georg Brandlba83f822010-03-14 09:50:54 +00004244- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4245 now also used by regrtest to run all the tests in a temporary directory. The
4246 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent

Georg Brandlba83f822010-03-14 09:50:54 +00004284- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4285 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4286 returning NULL. The macro now returns a statically allocated empty string
4287 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004340 file position when calling `truncate()`. It would previously change the file
4341 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004342 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4345 class used to represent files stored inside an archive. The new
4346 implementation is significantly faster and can be wrapped in a
4347 ``io.BufferedReader`` object for more speedups. It also solves an issue
4348 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4361 encoded string for them. This ensures that the upload and register commands
4362 send the correct values to PyPI without any error.

4448 effects of this change are in the extension modules, but some core functions
4449 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4450 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004633- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4634 decimal string that's guaranteed to round back to x under correct rounding
4635 (with round-half-to-even rounding mode). Previously it gave a string based on
4636 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4637 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4638 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004639
Georg Brandlba83f822010-03-14 09:50:54 +00004640- Issue #7117: On almost all platforms: float-to-string and string-to-float
4641 conversions within Python are now correctly rounded. Places these conversions
4642 occur include: str for floats and complex numbers; the float and complex
4643 constructors; old-style and new-style numeric formatting; serialization and
4644 deserialization of floats and complex numbers using marshal, pickle and json;
4645 parsing of float and imaginary literals in Python code; Decimal-to-float
4646 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004647
Georg Brandlba83f822010-03-14 09:50:54 +00004648 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4649 providing correctly-rounded strtod and dtoa C functions. This code is
4650 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4651 the C compiler. There may be a small number of platforms on which correct
4652 operation of this code cannot be guaranteed, so the code is not used: notably,
4653 this applies to platforms where the C double format is not IEEE 754 binary64,
4654 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4655 and Python's configure script is unable to determine how to change the FPU
4656 precision. On these platforms conversions use the platform strtod and dtoa,
4657 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004659- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4660 uses the correctly-rounded string <-> float conversions described above (when
4661 available), and so produces correctly rounded results that will display nicely
4662 under the float repr. There are two related small changes: (1) round now
4663 accepts any class with an ``__index__()`` method for its second argument (but
4664 no longer accepts floats for the second argument), and (2) an excessively
4665 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4666 raises an exception.

4816 of 12. Previously, the behavior the same but with a default precision of 6.
4817 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00004959- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4960 existing .py counterpart, override the co_filename attributes of all code
4961 objects if the original filename is obsolete (which can happen if the file has

5016
Georg Brandlba83f822010-03-14 09:50:54 +00005017- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5018 file objects with closefd=False. The file descriptor is still kept open but
5019 the file object behaves like a closed file. The ``FileIO`` object also got a
5020 new readonly attribute ``closefd``.

5039
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005040- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00005043- On windows, ``os.chdir()`` given unicode was not working if
5044 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5045 this code path is really executed because I cannot move to such directory on
5046 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005048- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5049 element is temporarily replaced with an equivalent frozenset. But the
5050 eventual KeyError would always report the empty ``frozenset()`` as the missing
5051 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005071- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5072 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5073 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5074 of using the replace error handler in PyUnicode_DecodeUTF8().
5075
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005076- Issue #3739: The unicode-internal encoder now reports the number of characters

5078
Georg Brandlba83f822010-03-14 09:50:54 +00005079- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5081 gives improved memory leak detection when running under Valgrind, while taking
5082 advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006452- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6453 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6454 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6455 ``printf`` function, whereas PyString_FromFormat has an independent
6456 implementation and uses "%zd" on all platforms for size_t values.
6457 This makes a difference on win64, where ``printf`` needs "%Id" to display
6458 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00006478 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Brett Cannon1eaf0742008-09-02 01:25:16 +00006553 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6554 for catch_warnings() also led to an improvement in the raising of a
6555 DeprecationWarning related to warnings.warn_explicit().
6556
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006557- The deprecation warnings for the old camelCase threading API were removed.

6579
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006580- Issue #2975: When compiling several extension modules with Visual Studio 2008
6581 from the same python interpreter, some environment variables would grow
6582 without limit.
6583
Benjamin Peterson37346b22008-08-23 20:27:43 +00006584- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6585 exploitation of poor argument checking.
6586
Gerhard Häringef2276b2008-09-12 13:54:06 +00006587- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

6600 wrapper for warnings.catch_warnings() that makes it easier to check
6601 that expected warning messages are being reported.
6602

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006621What's New in Python 2.6 beta 3?
6622================================
6623
Barry Warsaw07a4a382008-08-21 01:15:08 +00006624*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006625
6626Core and Builtins
6627-----------------
6628
Guido van Rossumf8402962008-08-20 15:01:50 +00006629- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6630 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6631 extensions do not automatically benefit from the class attribute
6632 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6633 to their tp_flags field if they care. This is a backwards
6634 compatibility feature; in 3.0, all types will use the cache by
6635 default.
6636
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006637- Keyword arguments can now follow starred arguments. (``f(a, *args,
6638 keyword=23)`` is now valid syntax.)
6639
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006640- ctypes function pointers that are COM methods have a boolean True
6641 value again.
6642
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006643- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6644 by denying s# to parse objects that have a releasebuffer procedure,
6645 and introducing s*.
6646
Georg Brandl1e13ea92008-08-11 09:07:59 +00006647- Issue #3537: Fix an assertion failure when an empty but presized dict
6648 object was stored in the freelist.
6649
Mark Dickinsonb6467572008-08-04 21:30:09 +00006650- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6651 ValueError consistently across platforms.
6652
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006653- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6654 (64bit Unix, for example), unichr() would truncate its argument and return
6655 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6656
Neal Norwitze7d8be82008-07-31 17:17:14 +00006657- Apply security patches from Apple.
6658
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006659- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6660 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6661
Antoine Pitrou92f82162008-07-25 22:22:08 +00006662- Issue #1819: function calls with several named parameters are now on
6663 average 35% faster (as measured by pybench).
6664
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006665- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6666 the python debugger steps into a class statement: the free variables (local
6667 variables defined in an outer scope) would be deleted from the outer scope.
6668
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006669- Issue #2620: Overflow checking when allocating or reallocating memory
6670 was not always being done properly in some python types and extension
6671 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6672 all been updated to perform better checks and places in the code that
6673 would previously leak memory on the error path when such an allocation
6674 failed have been fixed.
6675

6677-------
6678
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006679- Issue #3612: Added some missing basic types in ctypes.wintypes.
6680
Benjamin Petersone977ad42008-08-20 01:42:01 +00006681- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6682 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6683
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006684- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6685 version reported by these tools does not necessarily follow the python
6686 version numbering scheme, so the module is less strict when parsing it.
6687
Nick Coghlanf70385a2008-08-18 12:42:46 +00006688- Issue #2235: Added Py3k warnings for types which will become unhashable
6689 under the stricter __hash__ inheritance rules in 3.0. Several types
6690 which did not meet the rules for hash invariants and were already
6691 unhashable in 3.0 have now been explicitly flagged as unhashable in
6692 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6693 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6694
Brett Cannon88f801d2008-08-18 00:46:22 +00006695- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6696 imported into the module but exposed as part of the module's API.
6697
Brett Cannon7b96f072008-08-18 00:41:11 +00006698- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6699
Brett Cannon46225e72008-08-18 00:36:52 +00006700- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006702- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6703
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006704- Issue #3575: Incremental decoder's decode function now takes bytearray
6705 by using 's*' instead of 't#'.
6706
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006707- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006708 fails unicode conversion on 2nd parameter. (windows only)
6709
Georg Brandl222e2082010-08-01 22:27:39 +00006710- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006711 in a redirect.
6712
Brett Cannonabe423e2008-08-16 21:47:07 +00006713- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006714 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006715
Facundo Batistaeb90b782008-08-16 14:44:07 +00006716- Issue #2776: fixed small issue when handling an URL with double slash
6717 after a 302 response in the case of not going through a proxy.
6718
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006719- Issue #2676: in the email package, content-type parsing was hanging on
6720 pathological input because of quadratic or exponential behaviour of a
6721 regular expression.
6722
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006723- Issue #3476: binary buffered reading through the new "io" library is now
6724 thread-safe.
6725
Brett Cannonbf3157b2008-08-14 05:00:03 +00006726- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6727 since mimetools itself is deprecated. Because modules are cached, all
6728 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6729
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006730- Issue #3134: shutil referenced undefined WindowsError symbol.
6731
Robert Schuppenies14646332008-08-10 11:01:53 +00006732- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6733 menu entries were not deleted.
6734
Brett Cannon83e81842008-08-09 23:30:55 +00006735- Copied the implementation of reduce() to _functools.reduce() to have a
6736 version that did not raise a DeprecationWarning under -3.
6737
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006738- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6739 a MemoryError rather than silently stop the iteration.
6740
Guido van Rossum59ce9012008-08-09 14:55:34 +00006741- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6742 to _sre.compile() will now be rejected. This should not affect anybody
6743 since the re.compile() function never generates invalid re-bytecode.
6744
Skip Montanaroa032bf42008-08-08 22:52:51 +00006745- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6746 upon first access it can be automatically initialized from the csv file if
6747 it wasn't initialized during instantiation.
6748
Brett Cannon3aa2a492008-08-06 22:28:09 +00006749- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6750 the reload() built-in has been removed.
6751
Brett Cannon7e30b672008-08-04 21:52:25 +00006752- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006753 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006764 asking for a specific length. This problem only affected files opened
6765 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006766

6791 file name rather than a ZipInfo instance, so files are extracted with
6792 mode 0600 rather than 000 under Unix.
6793

6811 regarding lack of coverage of new-style classes have also been
6812 removed, since the coverage is now fairly reasonable.

6822
Georg Brandl3e483f62008-07-16 22:57:41 +00006823- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6824 its methods now allow for items objects that can be converted to
6825 an integer using operator.index().
6826
Mark Dickinson64b7e502008-07-16 09:40:03 +00006827- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6828 produced a ValueError instead of giving the correct float.
6829
Eric Smitha5fa5a22008-07-16 00:11:49 +00006830- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Nick Coghlan6d6bd442008-07-15 15:40:22 +00006837- Issue #2235: __hash__ is once again inherited by default. To allow
6838 collections.Hashable to remain meaningful in the presence of the
6839 default hash implementation (object.__hash__), it is now possible
6840 to explicit block inheritance of hash by setting __hash__=None at
6841 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6842 level.
6843
Nick Coghlanb028f502008-07-13 14:52:36 +00006844- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6845 the parent module cannot be found while performing an absolute import.
6846 This means that an incorrectly defined __package__ attribute will
6847 now only prevent relative imports in that module rather than causing
6848 all imports from that module to fail.
6849
Nick Coghlan14ff9942008-07-08 14:21:42 +00006850- Issue #2517: Allow unicode messages in Exceptions again by correctly

6861
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006862- Issue #3004: Minor change to slice.indices(): the start and stop
6863 arguments are now treated identically, making the behaviour easier
6864 to describe and understand. For example, slice(None, -10,
6865 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6866 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6867 10, -1).

6910 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006911 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007321 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007322
7323 This is controlled by the configure argument ``--with-universal-archs``:
7324

7326
7327 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7328
7329 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

7370 two handlers that derive the same default base class.

Christian Heimese74c8f22008-04-19 02:23:57 +00007372- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007383- Issue #1631171: Re-implement the 'warnings' module in C (the
7384 original Python code has been kept as backup). This will allow for
7385 using the 'warning's machinery in such places as the parser where
7386 use of pure Python code is not possible. Both the ``showarning()``
7387 and ``formatwarning()`` gain an optional 'line' argument which is
7388 not called by default for backwards-compatibility reasons. Setting
7389 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00007453- Issue #2550: The approach used by client/server code for obtaining
7454 ports to listen on in network-oriented tests has been refined in an
7455 effort to facilitate running multiple instances of the entire
7456 regression test suite in parallel without issue.
7457 test_support.bind_port() has been fixed such that it will always
7458 return a unique port -- which wasn't always the case with the
7459 previous implementation, especially if socket options had been set
7460 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7461 new implementation of bind_port() will actually raise an exception
7462 if it is passed an AF_INET/SOCK_STREAM socket with either the
7463 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7464 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7465 the socket it's been passed. This currently only applies to
7466 Windows. This option prevents any other sockets from binding to the
7467 host/port we've bound to, thus removing the possibility of the
7468 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7469 when a second SOCK_STREAM socket binds and accepts to a host/port
7470 that's already been bound by another socket. The optional preferred
7471 port parameter to bind_port() has been removed. Under no
7472 circumstances should tests be hard coding ports!
7473
7474 test_support.find_unused_port() has also been introduced, which will
7475 pass a temporary socket object to bind_port() in order to obtain an
7476 unused port. The temporary socket object is then closed and
7477 deleted, and the port is returned. This method should only be used
7478 for obtaining an unused port in order to pass to an external program
7479 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7480 a parameter to a server-oriented class that doesn't give you direct
7481 access to the underlying socket used.
7482
7483 Finally, test_support.HOST has been introduced, which should be used
7484 for the host argument of any relevant socket calls (i.e. bind and
7485 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007486
7487 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007488 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007489 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7490 test_asynchat and test_socket_ssl.
7491
Georg Brandl3ee81df2008-05-17 18:14:43 +00007492 It is now possible for multiple instances of the regression test
7493 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007659- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
7660 values on 32-bit vs. 64-bit python interpreters. Both were correct,
7661 but they now both return a signed integer object for consistency.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007677 optional: it defaults to the traceback of the exception that is

Fred Drakea8ee94b2008-03-01 02:45:07 +00007762- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007763 644. The mode is now inherited from the py file.

Eric Smitha73fbe72008-02-23 03:09:44 +00007772- Added the future_builtins module, which contains hex() and oct().
7773 These are the PEP 3127 version of these functions, designed to be
7774 compatible with the hex() and oct() builtins from Python 3.0. They
7775 differ slightly in their output formats from the existing, unchanged
7776 Python 2.6 builtins. The expected usage of the future_builtins
7777 module is:
7778 from future_builtins import hex, oct
7779
Eric Smith7ef40bf2008-02-20 23:34:22 +00007780- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7781 exponents for exponents with absolute value < 100. Follows C99
7782 standard. This is a change on Windows, which would use 3 digits.
7783 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7784 so that any alterations it does to the resulting string will be
7785 available in stringlib/formatter.h (for float.__format__).
7786
Eric Smith5a3c1352008-02-19 13:21:56 +00007787- Implemented PEP 3101, Advanced String Formatting. This adds a new
7788 builtin format(); a format() method for str and unicode; a
7789 __format__() method to object, str, unicode, int, long, float, and
7790 datetime; the class string.Formatter; and the C API
7791 PyObject_Format().
7792
Georg Brandl3ee81df2008-05-17 18:14:43 +00007793- Fixed several potential crashes, all caused by specially crafted
7794 __del__ methods exploiting objects in temporarily inconsistent
7795 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007796
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007797- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007798 prevent a possible crash: an Abstract Base Class would try to access
7799 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007800
Georg Brandl3ee81df2008-05-17 18:14:43 +00007801- Fixed repr() and str() of complex numbers with infinity or nan as
7802 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007804- Clear all free lists during a gc.collect() of the highest generation
7805 in order to allow pymalloc to free more arenas. Python may give back
7806 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007807
Georg Brandl3ee81df2008-05-17 18:14:43 +00007808- Issue #2045: Fix an infinite recursion triggered when printing a
7809 subclass of collections.defaultdict, if its default_factory is set
7810 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007811
Christian Heimesf75dbef2008-02-08 00:11:31 +00007812- Fixed a minor memory leak in dictobject.c. The content of the free
7813 list was not freed on interpreter shutdown.
7814
Georg Brandl21e99f42010-03-07 15:23:59 +00007815- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007816 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007817
Georg Brandl3ee81df2008-05-17 18:14:43 +00007818- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7819 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007820 to compact the internal free lists of pre-allocted ints and floats.
7821
Georg Brandl3ee81df2008-05-17 18:14:43 +00007822- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7823 calls. Python expected the return type int but the fork familie
7824 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007825
Georg Brandl3ee81df2008-05-17 18:14:43 +00007826- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7827 appear in the same code unit.

7836 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007837
Georg Brandl3ee81df2008-05-17 18:14:43 +00007838- Patch #1473257: generator objects gain a gi_code attribute. This is
7839 the same object as the func_code attribute of the function that
7840 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007841
Georg Brandl3ee81df2008-05-17 18:14:43 +00007842- Issue #1920: "while 0" statements were completely removed by the
7843 compiler, even in the presence of an "else" clause, which is
7844 supposed to be run when the condition is false. Now the compiler
7845 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007846
Guido van Rossumeead05f2008-01-24 18:21:02 +00007847- A few crashers fixed: weakref_in_del.py (issue #1377858);
7848 loosing_dict_ref.py (issue #1303614, test67.py);
7849 borrowed_ref_[34].py (not in tracker).
7850
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007851- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007852 suppressed while an extension is loaded by calling SetErrorMode in
7853 dynload_win.c. The error is still reported properly.
7854
Georg Brandl3ee81df2008-05-17 18:14:43 +00007855- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007856 several extension methods and modules do not work without unicode
7857 support.
7858
Georg Brandl26543b12008-01-21 18:36:51 +00007859- Issue #1882: when compiling code from a string, encoding cookies in the
7860 second line of code were not always recognized correctly.
7861
Georg Brandl14404b62008-01-19 19:27:05 +00007862- Issue #1679: "0x" was taken as a valid integer literal.
7863
Georg Brandl6caad7d2008-01-26 14:19:22 +00007864- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007865 added.
7866
Christian Heimesc94e2b52008-01-14 04:13:37 +00007867- sys.float_info / PyFloat_GetInfo: The floating point information
7868 object was converted from a dict to a specialized structseq object.
7869
Georg Brandl3ee81df2008-05-17 18:14:43 +00007870- Patch #1816: Added sys.flags structseq. It exposes the status of
7871 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007872
Georg Brandl3ee81df2008-05-17 18:14:43 +00007873- Objects/structseq.c: Implemented new structseq representation. The
7874 patch makes structseqs (e.g. the return value of os.stat) more
7875 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007876
Georg Brandl3ee81df2008-05-17 18:14:43 +00007877- Patch #1700288: added a type attribute cache that caches method
7878 accesses, resulting in speedups in heavily object-oriented code.

7886 envvar and sys.dont_write_bytecode attribute. All these can be set
7887 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007888
Georg Brandl3ee81df2008-05-17 18:14:43 +00007889- Improve some exception messages when Windows fails to load an
7890 extension module. Now we get for example '%1 is not a valid Win32
7891 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007902- Compiler now generates simpler and faster code for dictionary
7903 literals. The oparg for BUILD_MAP now indicates an estimated
7904 dictionary size. There is a new opcode, STORE_MAP, for adding
7905 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007950 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7951 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007952
Georg Brandl3ee81df2008-05-17 18:14:43 +00007953- Issue #1686386: Tuple's tp_repr did not take into account the
7954 possibility of having a self-referential tuple, which is possible
7955 from C code. Nor did object's tp_str consider that a type's tp_str
7956 could do something that could lead to an inifinite recursion.
7957 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7958 issues.

7961 'print' statement to write to a file since the GIL was not released
7962 as needed. Now PyObject_Print() does the right thing along with
7963 various tp_print implementations of the built-in types and those in
7964 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007974 PyObject_Call() never calling back out to Python code to trigger
7975 recursion depth updates/checks. Required the creation of a static

8025
Guido van Rossum143b5642007-03-23 04:58:42 +00008026- Bug #1683368: The object.__init__() and object.__new__() methods are
8027 now stricter in rejecting excess arguments. The only time when
8028 either allows excess arguments is when it is not overridden and the
8029 other one is. For backwards compatibility, when both are
8030 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008031 warning later). Also, type.__init__() insists on the same signature
8032 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008034- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8035 object to complex using its __complex__() method before falling back
8036 to the __float__() method. Therefore, the functions in the cmath
8037 module now can operate on objects that define a __complex__()
8038 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008056- Bug #1678647: write a newline after printing an exception in any
8057 case, even when converting the value to a string failed.
8058
Georg Brandl871f1bc2007-03-12 13:17:36 +00008059- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008060 its argument, if it exists. If not, it will work like before. This
8061 allows customizing the output of dir() in the presence of a
8062 __getattr__().

8072 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008073
Georg Brandlaa2321b2007-03-07 00:40:28 +00008074- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008075 makes the filenames the warning module prints much more sensible
8076 when a PYTHONSTARTUP file is used.

8091
Georg Brandl3ee81df2008-05-17 18:14:43 +00008092- When printing an unraisable error, don't print exceptions. before

8660
Georg Brandl92a6bae2007-03-13 17:43:32 +00008661- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008662 are set for invalid interpolation sequences that would lead to
8663 errors on reading back those values.

8719 TestCase and TestSuite subclasses (not instances) are no longer
8720 accepted in TestSuite.addTest(). This should cause no
8721 incompatibility since it never made sense with ordinary subclasses
8722 -- the failure just occurred later, with a more cumbersome
8723 exception.

Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009002
Georg Brandl3ee81df2008-05-17 18:14:43 +00009003- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009004 that the SMTP.starttls() caller no longer needs to call ehlo()
9005 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009006 does not claim to support starttls. Adds the
9007 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9088 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9089 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00009091

Georg Brandl3ee81df2008-05-17 18:14:43 +00009106 time so that opening a database previously created with the DB_DUP
9107 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9108 opens. Specifically: dictionary assignment to a DB object will
9109 replace all values for a given key when the database allows
9110 duplicate values. DB users should use DB.put(k, v) when they want
9111 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009112

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009399- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00009400 periodic threadstate and signal checking in tight loops. By
9401 default, this option is turned-off. It should only be enabled in
9402 debugged, performance critical applications.

9458 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009459
Georg Brandl3ee81df2008-05-17 18:14:43 +00009460- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9461 to ``PyTuple_SetItem``, it can be used to populate a brand new
9462 frozenset; but it does not steal a reference to the added item.

9474
Georg Brandl3ee81df2008-05-17 18:14:43 +00009475- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9476 of w# format code incorrectly truncated the length to an int, even
9477 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9478 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009479

Georg Brandl3ee81df2008-05-17 18:14:43 +00009508- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9509 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009510
Georg Brandl3ee81df2008-05-17 18:14:43 +00009511- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
