Ned Deily18fae3f2013-01-31 01:24:55 -08001246- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1247 In particular, fix extension module build failures when trying to use
1248 32-bit-only installer Pythons on systems with Xcode 4 (currently
1249 OS X 10.8, 10.7, and optionally 10.6).
1250 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1251 * Since Xcode 4 removes ppc support, extension module builds now
1252 check for ppc compiler support and by default remove ppc and
1253 ppc64 archs when they are not available.
1254 * Extension module builds now revert to using system installed
1255 headers and libs (/usr and /System/Library) if the SDK used
1256 to build the interpreter is not installed or has moved.
1257 * Try to avoid building extension modules with deprecated
1258 and problematic Apple llvm-gcc compiler. If original compiler
1259 is not available, use clang instead by default.

1614 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001690- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1691 Distutils-based packages with C extension modules may fail because
1692 Apple has removed gcc-4.2, the version used to build python.org
1693 64-bit/32-bit Pythons. If the user does not explicitly override
1694 the default C compiler by setting the CC environment variable,
1695 Distutils will now attempt to compile extension modules with clang
1696 if gcc-4.2 is required but not found. Also as a convenience, if
1697 the user does explicitly set CC, substitute its value as the default
1698 compiler in the Distutils LDSHARED configuration variable for OS X.
1699 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1700 SDK, neither of which are available in Xcode 4. This change does not
1701 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001951- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1952 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1953 interpreter process. This could cause failures in non-Distutils subprocesses
1954 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001955 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001956 deployment target only in the environment of each build subprocess. It is
1957 still possible to globally override the default by setting
1958 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1959 greater or equal to the default value, the value with which the interpreter
1960 was built.

Barry Warsawc5643282011-07-19 17:06:30 -04001988- sys.setcheckinterval() now updates the current ticker count as well as
1989 updating the check interval, so if the user decreases the check interval,
1990 the ticker doesn't have to wind down to zero from the old starting point
1991 before the new interval takes effect. And if the user increases the
1992 interval, it makes sure the new limit takes effect right away rather have an
1993 early task switch before recognizing the new interval.

2939
R. David Murray20ad3632010-10-01 15:48:49 +00002940- Issue #10004: quoprimime no longer generates a traceback when confronted
2941 with invalid characters after '=' in a Q-encoded word.
2942
Antoine Pitrou66b5df62010-09-27 18:16:46 +00002943- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
2944 received. Now sendall() properly calls signal handlers if necessary,

2957 handles non-blocking readinto() returning None correctly.
2958

2960 SSLSocket.sendto() to match the corresponding socket methods. Also,
2961 fix various SSLSocket methods to raise socket.error rather than an
2962 unhelpful TypeError when called on an unconnected socket. Original patch
2963 by Andrew Bennetts.
2964
Raymond Hettinger74f869e2010-09-13 22:14:36 +00002965- Issue #9826: OrderedDict.__repr__ can now handle self-referential

2972
Raymond Hettinger20397532010-09-12 02:11:45 +00002973- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2974 This prevents user-created self-referencing ordered dictionaries from
2975 becoming permanently uncollectable GC garbage. The downside is that
2976 removing __del__ means that the internal doubly-linked list has to wait for
2977 GC collection rather than freeing memory immediately when the refcnt drops
2978 to zero.
2979
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002980- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00002981 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002982 value.
2983
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002984- Issue #9792: In case of connection failure, socket.create_connection()
2985 would swallow the exception and raise a new one, making it impossible
2986 to fetch the original errno, or to filter timeout errors. Now the
2987 original error is re-raised.
2988
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002989- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2990 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2991 be updated back after the system call. Original patch by Brian Brazil.
2992
Antoine Pitroudca9de92010-09-04 17:52:26 +00002993- Issue #1100562: Fix deep-copying of objects derived from the list and
2994 dict types. Patch by Michele Orrù and Björn Lindqvist.

2997 ConfigParser.write.
2998
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002999- Issue #808164: Fixed socket.close to avoid references to globals, to
3000 avoid issues when socket.close is called from a __del__ method.
3001
Terry Reedyd2d2ae92010-11-11 23:22:19 +00003002- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
3003 can be set to False to turn off the previously undocumented 'popularity'
3004 heuristic. Patch by Terry Reedy and Eli Bendersky
3005
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003006- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3007 falling into recursion.
3008
R. David Murray7c4bf552010-08-25 01:45:57 +00003009- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3010 character years even if the message contains RFC822 two character years.
3011
Daniel Stutzbach91287322010-08-24 21:09:30 +00003012- Issue #8750: Fixed MutableSet's methods to correctly handle
3013 reflexive operations, namely x -= x and x ^= x.

3024 module now correctly return a set. (Patch by Eli Bendersky.)
3025
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003026- Issue #9617: Signals received during a low-level write operation aren't
3027 ignored by the buffered IO layer anymore.
3028
Benjamin Peterson52c36052010-08-21 03:03:22 +00003029- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3030 are not held onto after they are deleted elsewhere.
3031
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003032- Issue #9626: the view methods for collections.OrderedDict() were returning
3033 the unordered versions inherited from dict. Those methods are now
3034 overridden to provide ordered views.

3043
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003044- Issue #9550: a BufferedReader could issue an additional read when the
3045 original read request had been satisfied, which could block indefinitely
3046 when the underlying raw IO channel was e.g. a socket. Report and original
3047 patch by Jason V. Miller.
3048
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003049- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00003067- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
3068 This is how it is supposed to work, wget and curl do the same. Previous
3069 behavior was wrong.

3077 the option character for the added 'h/help' option if prefix_chars
3078 does not contain a '-', instead of raising an error.
3079

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003437- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

3440 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3441 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3453 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003798 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

3821-----------------
3822
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003823- Issue #7301: Add environment variable $PYTHONWARNINGS.
3824
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003825- Issue #8329: Don't return the same lists from select.select when no fds are
3826 changed.
3827
Georg Brandlfee0f442010-05-22 21:26:21 +00003828- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003829 on 64-bit machines. The shift count for either left or right shift is
3830 permitted to be up to sys.maxsize.
3831
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003832- Ensure that tokenization of identifiers is not affected by locale.

3837
Georg Brandlfee0f442010-05-22 21:26:21 +00003838- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3839 with a non-empty format string. This is an effort to future-proof user
3840 code. If a derived class does not currently implement __format__ but later
3841 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003842 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003843 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003844
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003845- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00003858- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003859 (SIGINT). If an error occurs while importing the site module, the error is

3875
Georg Brandlfee0f442010-05-22 21:26:21 +00003876- Issue #8257: The Decimal construct now accepts a float instance directly,
3877 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003878
3879 >>> Decimal(1.1)
3880 Decimal('1.100000000000000088817841970012523233890533447265625')
3881
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003882- collections.Counter() now supports a subtract() method.
3883
Georg Brandlfee0f442010-05-22 21:26:21 +00003884- The functools module now has a total_ordering() class decorator to simplify
3885 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003886
Georg Brandlfee0f442010-05-22 21:26:21 +00003887- The functools module also adds cmp_to_key() as a tool to transition old-style
3888 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003889

Georg Brandlfee0f442010-05-22 21:26:21 +00003893- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3894 InvalidOperation instead of returning False. (Comparisons involving a quiet
3895 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3896 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003897
Georg Brandlfee0f442010-05-22 21:26:21 +00003898- Issue #2531: Comparison operations between floats and Decimal instances now
3899 return a result based on the numeric values of the operands; previously they
3900 returned an arbitrary result based on the relative ordering of id(float) and
3901 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003902
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003903- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003904 argument `-` which tells it to read files to compile from stdin. Each line is
3905 read on demand and the named file is compiled immediately. (Original patch by
3906 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00003911- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3912 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003913 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003914
Georg Brandlfee0f442010-05-22 21:26:21 +00003915- Comparisons using one of <, <=, >, >= between a complex instance and a
3916 Fractions instance now raise TypeError instead of returning True/False. This
3917 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3918 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004280- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4281 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4282 returning NULL. The macro now returns a statically allocated empty string
4283 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004336 file position when calling `truncate()`. It would previously change the file
4337 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004338 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4341 class used to represent files stored inside an archive. The new
4342 implementation is significantly faster and can be wrapped in a
4343 ``io.BufferedReader`` object for more speedups. It also solves an issue
4344 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004355- Issue #7748: Since unicode values are supported for some metadata options in
4356 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4357 encoded string for them. This ensures that the upload and register commands
4358 send the correct values to PyPI without any error.

4444 effects of this change are in the extension modules, but some core functions
4445 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4446 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004629- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4630 decimal string that's guaranteed to round back to x under correct rounding
4631 (with round-half-to-even rounding mode). Previously it gave a string based on
4632 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4633 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4634 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004635
Georg Brandlba83f822010-03-14 09:50:54 +00004636- Issue #7117: On almost all platforms: float-to-string and string-to-float
4637 conversions within Python are now correctly rounded. Places these conversions
4638 occur include: str for floats and complex numbers; the float and complex
4639 constructors; old-style and new-style numeric formatting; serialization and
4640 deserialization of floats and complex numbers using marshal, pickle and json;
4641 parsing of float and imaginary literals in Python code; Decimal-to-float
4642 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004643
Georg Brandlba83f822010-03-14 09:50:54 +00004644 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4645 providing correctly-rounded strtod and dtoa C functions. This code is
4646 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4647 the C compiler. There may be a small number of platforms on which correct
4648 operation of this code cannot be guaranteed, so the code is not used: notably,
4649 this applies to platforms where the C double format is not IEEE 754 binary64,
4650 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4651 and Python's configure script is unable to determine how to change the FPU
4652 precision. On these platforms conversions use the platform strtod and dtoa,
4653 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004655- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4656 uses the correctly-rounded string <-> float conversions described above (when
4657 available), and so produces correctly rounded results that will display nicely
4658 under the float repr. There are two related small changes: (1) round now
4659 accepts any class with an ``__index__()`` method for its second argument (but
4660 no longer accepts floats for the second argument), and (2) an excessively
4661 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4662 raises an exception.

4812 of 12. Previously, the behavior the same but with a default precision of 6.

4923
Georg Brandl29c6a282009-04-05 20:23:13 +00004924- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00004925 were suppressing all exceptions. These include list(), filter(), map(),

4927
Benjamin Peterson596d3062009-01-19 15:42:23 +00004928- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00004955- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4956 existing .py counterpart, override the co_filename attributes of all code
4957 objects if the original filename is obsolete (which can happen if the file has
4958 been renamed, moved, or if it is accessed through different paths). Patch by

5006
Georg Brandlba83f822010-03-14 09:50:54 +00005007- Issue #3689: The list reversed iterator now supports __length_hint__ instead

5012
Georg Brandlba83f822010-03-14 09:50:54 +00005013- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5014 file objects with closefd=False. The file descriptor is still kept open but
5015 the file object behaves like a closed file. The ``FileIO`` object also got a
5016 new readonly attribute ``closefd``.

5035
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005036- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005037 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00005039- On windows, ``os.chdir()`` given unicode was not working if
5040 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5041 this code path is really executed because I cannot move to such directory on
5042 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005044- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5045 element is temporarily replaced with an equivalent frozenset. But the
5046 eventual KeyError would always report the empty ``frozenset()`` as the missing
5047 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005067- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5068 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5069 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5070 of using the replace error handler in PyUnicode_DecodeUTF8().
5071
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005072- Issue #3739: The unicode-internal encoder now reports the number of characters

5074
Georg Brandlba83f822010-03-14 09:50:54 +00005075- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5077 gives improved memory leak detection when running under Valgrind, while taking
5078 advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006448- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6449 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6450 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6451 ``printf`` function, whereas PyString_FromFormat has an independent
6452 implementation and uses "%zd" on all platforms for size_t values.
6453 This makes a difference on win64, where ``printf`` needs "%Id" to display
6454 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00006474 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

6477 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6478 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006549 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6550 for catch_warnings() also led to an improvement in the raising of a
6551 DeprecationWarning related to warnings.warn_explicit().
6552
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006553- The deprecation warnings for the old camelCase threading API were removed.
6554

Gregory P. Smithd7122032008-09-02 05:36:11 +00006564- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
6565 non-integer floating point number.
6566
Vinay Sajip65d66e12008-09-04 07:31:21 +00006567- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

6574 _check_logger_class from multiprocessing.
6575
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006576- Issue #2975: When compiling several extension modules with Visual Studio 2008
6577 from the same python interpreter, some environment variables would grow
6578 without limit.
6579
Benjamin Peterson37346b22008-08-23 20:27:43 +00006580- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6581 exploitation of poor argument checking.
6582
Gerhard Häringef2276b2008-09-12 13:54:06 +00006583- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
6584
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00006585- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
6586 remaining ones have "pysqlite_" prefix.
6587
Gerhard Häringe6872eb2008-09-12 22:33:22 +00006588- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

6596 wrapper for warnings.catch_warnings() that makes it easier to check
6597 that expected warning messages are being reported.
6598
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00006599- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006617What's New in Python 2.6 beta 3?
6618================================
6619
Barry Warsaw07a4a382008-08-21 01:15:08 +00006620*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006621
6622Core and Builtins
6623-----------------
6624
Guido van Rossumf8402962008-08-20 15:01:50 +00006625- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6626 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6627 extensions do not automatically benefit from the class attribute
6628 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6629 to their tp_flags field if they care. This is a backwards
6630 compatibility feature; in 3.0, all types will use the cache by
6631 default.
6632
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006633- Keyword arguments can now follow starred arguments. (``f(a, *args,
6634 keyword=23)`` is now valid syntax.)
6635
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006636- ctypes function pointers that are COM methods have a boolean True
6637 value again.
6638
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006639- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6640 by denying s# to parse objects that have a releasebuffer procedure,
6641 and introducing s*.
6642
Georg Brandl1e13ea92008-08-11 09:07:59 +00006643- Issue #3537: Fix an assertion failure when an empty but presized dict
6644 object was stored in the freelist.
6645
Mark Dickinsonb6467572008-08-04 21:30:09 +00006646- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6647 ValueError consistently across platforms.
6648
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006649- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6650 (64bit Unix, for example), unichr() would truncate its argument and return
6651 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6652
Neal Norwitze7d8be82008-07-31 17:17:14 +00006653- Apply security patches from Apple.
6654
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006655- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6656 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6657
Antoine Pitrou92f82162008-07-25 22:22:08 +00006658- Issue #1819: function calls with several named parameters are now on
6659 average 35% faster (as measured by pybench).
6660
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006661- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6662 the python debugger steps into a class statement: the free variables (local
6663 variables defined in an outer scope) would be deleted from the outer scope.
6664
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006665- Issue #2620: Overflow checking when allocating or reallocating memory
6666 was not always being done properly in some python types and extension
6667 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6668 all been updated to perform better checks and places in the code that
6669 would previously leak memory on the error path when such an allocation
6670 failed have been fixed.
6671
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006672Library
6673-------
6674
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006675- Issue #3612: Added some missing basic types in ctypes.wintypes.
6676
Benjamin Petersone977ad42008-08-20 01:42:01 +00006677- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6678 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6679
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006680- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6681 version reported by these tools does not necessarily follow the python
6682 version numbering scheme, so the module is less strict when parsing it.
6683
Nick Coghlanf70385a2008-08-18 12:42:46 +00006684- Issue #2235: Added Py3k warnings for types which will become unhashable
6685 under the stricter __hash__ inheritance rules in 3.0. Several types
6686 which did not meet the rules for hash invariants and were already
6687 unhashable in 3.0 have now been explicitly flagged as unhashable in
6688 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6689 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6690
Brett Cannon88f801d2008-08-18 00:46:22 +00006691- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6692 imported into the module but exposed as part of the module's API.
6693
Brett Cannon7b96f072008-08-18 00:41:11 +00006694- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6695
Brett Cannon46225e72008-08-18 00:36:52 +00006696- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006698- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6699
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006700- Issue #3575: Incremental decoder's decode function now takes bytearray
6701 by using 's*' instead of 't#'.
6702
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006703- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006704 fails unicode conversion on 2nd parameter. (windows only)
6705
Georg Brandl222e2082010-08-01 22:27:39 +00006706- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006707 in a redirect.
6708
Brett Cannonabe423e2008-08-16 21:47:07 +00006709- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006710 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006711
Facundo Batistaeb90b782008-08-16 14:44:07 +00006712- Issue #2776: fixed small issue when handling an URL with double slash
6713 after a 302 response in the case of not going through a proxy.
6714
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006715- Issue #2676: in the email package, content-type parsing was hanging on
6716 pathological input because of quadratic or exponential behaviour of a
6717 regular expression.
6718
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006719- Issue #3476: binary buffered reading through the new "io" library is now
6720 thread-safe.
6721
Brett Cannonbf3157b2008-08-14 05:00:03 +00006722- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6723 since mimetools itself is deprecated. Because modules are cached, all
6724 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6725
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006726- Issue #3134: shutil referenced undefined WindowsError symbol.
6727
Robert Schuppenies14646332008-08-10 11:01:53 +00006728- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6729 menu entries were not deleted.
6730
Brett Cannon83e81842008-08-09 23:30:55 +00006731- Copied the implementation of reduce() to _functools.reduce() to have a
6732 version that did not raise a DeprecationWarning under -3.
6733
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006734- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6735 a MemoryError rather than silently stop the iteration.
6736
Guido van Rossum59ce9012008-08-09 14:55:34 +00006737- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6738 to _sre.compile() will now be rejected. This should not affect anybody
6739 since the re.compile() function never generates invalid re-bytecode.
6740
Skip Montanaroa032bf42008-08-08 22:52:51 +00006741- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6742 upon first access it can be automatically initialized from the csv file if
6743 it wasn't initialized during instantiation.
6744
Brett Cannon3aa2a492008-08-06 22:28:09 +00006745- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6746 the reload() built-in has been removed.
6747
Brett Cannon7e30b672008-08-04 21:52:25 +00006748- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006749 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006760 asking for a specific length. This problem only affected files opened
6761 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006762

6787 file name rather than a ZipInfo instance, so files are extracted with
6788 mode 0600 rather than 000 under Unix.
6789
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006790- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6791 argument in python 2.5, this broke code that subclassed Popen to include its
6792 own poll method. Fixed my moving _deadstate to an _internal_poll method.

6807 regarding lack of coverage of new-style classes have also been
6808 removed, since the coverage is now fairly reasonable.

6818
Georg Brandl3e483f62008-07-16 22:57:41 +00006819- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6820 its methods now allow for items objects that can be converted to
6821 an integer using operator.index().
6822
Mark Dickinson64b7e502008-07-16 09:40:03 +00006823- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6824 produced a ValueError instead of giving the correct float.
6825
Eric Smitha5fa5a22008-07-16 00:11:49 +00006826- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6827 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6828
Mark Dickinson7103aa42008-07-15 19:08:33 +00006829- Issue #3008: the float type has a new instance method 'float.hex'

Nick Coghlan6d6bd442008-07-15 15:40:22 +00006833- Issue #2235: __hash__ is once again inherited by default. To allow
6834 collections.Hashable to remain meaningful in the presence of the
6835 default hash implementation (object.__hash__), it is now possible
6836 to explicit block inheritance of hash by setting __hash__=None at
6837 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6838 level.
6839
Nick Coghlanb028f502008-07-13 14:52:36 +00006840- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6841 the parent module cannot be found while performing an absolute import.
6842 This means that an incorrectly defined __package__ attribute will
6843 now only prevent relative imports in that module rather than causing
6844 all imports from that module to fail.
6845
Nick Coghlan14ff9942008-07-08 14:21:42 +00006846- Issue #2517: Allow unicode messages in Exceptions again by correctly

6857
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006858- Issue #3004: Minor change to slice.indices(): the start and stop
6859 arguments are now treated identically, making the behaviour easier
6860 to describe and understand. For example, slice(None, -10,
6861 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6862 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6863 10, -1).

6906 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006907 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007317 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007318
7319 This is controlled by the configure argument ``--with-universal-archs``:

7366 two handlers that derive the same default base class.

Christian Heimese74c8f22008-04-19 02:23:57 +00007368- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007379- Issue #1631171: Re-implement the 'warnings' module in C (the
7380 original Python code has been kept as backup). This will allow for
7381 using the 'warning's machinery in such places as the parser where
7382 use of pure Python code is not possible. Both the ``showarning()``
7383 and ``formatwarning()`` gain an optional 'line' argument which is
7384 not called by default for backwards-compatibility reasons. Setting
7385 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00007449- Issue #2550: The approach used by client/server code for obtaining
7450 ports to listen on in network-oriented tests has been refined in an
7451 effort to facilitate running multiple instances of the entire
7452 regression test suite in parallel without issue.
7453 test_support.bind_port() has been fixed such that it will always
7454 return a unique port -- which wasn't always the case with the
7455 previous implementation, especially if socket options had been set
7456 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7457 new implementation of bind_port() will actually raise an exception
7458 if it is passed an AF_INET/SOCK_STREAM socket with either the
7459 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7460 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7461 the socket it's been passed. This currently only applies to
7462 Windows. This option prevents any other sockets from binding to the
7463 host/port we've bound to, thus removing the possibility of the
7464 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7465 when a second SOCK_STREAM socket binds and accepts to a host/port
7466 that's already been bound by another socket. The optional preferred
7467 port parameter to bind_port() has been removed. Under no
7468 circumstances should tests be hard coding ports!
7469
7470 test_support.find_unused_port() has also been introduced, which will
7471 pass a temporary socket object to bind_port() in order to obtain an
7472 unused port. The temporary socket object is then closed and
7473 deleted, and the port is returned. This method should only be used
7474 for obtaining an unused port in order to pass to an external program
7475 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7476 a parameter to a server-oriented class that doesn't give you direct
7477 access to the underlying socket used.
7478
7479 Finally, test_support.HOST has been introduced, which should be used
7480 for the host argument of any relevant socket calls (i.e. bind and
7481 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007482
7483 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007484 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007485 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7486 test_asynchat and test_socket_ssl.
7487
Georg Brandl3ee81df2008-05-17 18:14:43 +00007488 It is now possible for multiple instances of the regression test
7489 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007655- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
7656 values on 32-bit vs. 64-bit python interpreters. Both were correct,
7657 but they now both return a signed integer object for consistency.

Eric Smitha73fbe72008-02-23 03:09:44 +00007768- Added the future_builtins module, which contains hex() and oct().
7769 These are the PEP 3127 version of these functions, designed to be
7770 compatible with the hex() and oct() builtins from Python 3.0. They
7771 differ slightly in their output formats from the existing, unchanged
7772 Python 2.6 builtins. The expected usage of the future_builtins
7773 module is:
7774 from future_builtins import hex, oct
7775
Eric Smith7ef40bf2008-02-20 23:34:22 +00007776- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7777 exponents for exponents with absolute value < 100. Follows C99
7778 standard. This is a change on Windows, which would use 3 digits.
7779 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7780 so that any alterations it does to the resulting string will be
7781 available in stringlib/formatter.h (for float.__format__).
7782
Eric Smith5a3c1352008-02-19 13:21:56 +00007783- Implemented PEP 3101, Advanced String Formatting. This adds a new
7784 builtin format(); a format() method for str and unicode; a
7785 __format__() method to object, str, unicode, int, long, float, and
7786 datetime; the class string.Formatter; and the C API
7787 PyObject_Format().
7788
Georg Brandl3ee81df2008-05-17 18:14:43 +00007789- Fixed several potential crashes, all caused by specially crafted
7790 __del__ methods exploiting objects in temporarily inconsistent
7791 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007792
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007793- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007794 prevent a possible crash: an Abstract Base Class would try to access
7795 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007796

Georg Brandl3ee81df2008-05-17 18:14:43 +00007800- Clear all free lists during a gc.collect() of the highest generation
7801 in order to allow pymalloc to free more arenas. Python may give back
7802 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007803
Georg Brandl3ee81df2008-05-17 18:14:43 +00007804- Issue #2045: Fix an infinite recursion triggered when printing a
7805 subclass of collections.defaultdict, if its default_factory is set
7806 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007807
Christian Heimesf75dbef2008-02-08 00:11:31 +00007808- Fixed a minor memory leak in dictobject.c. The content of the free
7809 list was not freed on interpreter shutdown.
7810
Georg Brandl21e99f42010-03-07 15:23:59 +00007811- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007812 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007813
Georg Brandl3ee81df2008-05-17 18:14:43 +00007814- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7815 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007816 to compact the internal free lists of pre-allocted ints and floats.
7817
Georg Brandl3ee81df2008-05-17 18:14:43 +00007818- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7819 calls. Python expected the return type int but the fork familie
7820 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007821
Georg Brandl3ee81df2008-05-17 18:14:43 +00007822- Issue #1678380: Fix a bug that identifies 0j and -0j when they

7832 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007833
Georg Brandl3ee81df2008-05-17 18:14:43 +00007834- Patch #1473257: generator objects gain a gi_code attribute. This is
7835 the same object as the func_code attribute of the function that
7836 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007837
Georg Brandl3ee81df2008-05-17 18:14:43 +00007838- Issue #1920: "while 0" statements were completely removed by the
7839 compiler, even in the presence of an "else" clause, which is
7840 supposed to be run when the condition is false. Now the compiler
7841 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007842
Guido van Rossumeead05f2008-01-24 18:21:02 +00007843- A few crashers fixed: weakref_in_del.py (issue #1377858);
7844 loosing_dict_ref.py (issue #1303614, test67.py);
7845 borrowed_ref_[34].py (not in tracker).
7846
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007847- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007848 suppressed while an extension is loaded by calling SetErrorMode in
7849 dynload_win.c. The error is still reported properly.
7850
Georg Brandl3ee81df2008-05-17 18:14:43 +00007851- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007852 several extension methods and modules do not work without unicode
7853 support.
7854
Georg Brandl26543b12008-01-21 18:36:51 +00007855- Issue #1882: when compiling code from a string, encoding cookies in the
7856 second line of code were not always recognized correctly.
7857
Georg Brandl14404b62008-01-19 19:27:05 +00007858- Issue #1679: "0x" was taken as a valid integer literal.
7859
Georg Brandl6caad7d2008-01-26 14:19:22 +00007860- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007861 added.
7862
Christian Heimesc94e2b52008-01-14 04:13:37 +00007863- sys.float_info / PyFloat_GetInfo: The floating point information
7864 object was converted from a dict to a specialized structseq object.
7865
Georg Brandl3ee81df2008-05-17 18:14:43 +00007866- Patch #1816: Added sys.flags structseq. It exposes the status of
7867 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007868
Georg Brandl3ee81df2008-05-17 18:14:43 +00007869- Objects/structseq.c: Implemented new structseq representation. The
7870 patch makes structseqs (e.g. the return value of os.stat) more
7871 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007872
Georg Brandl3ee81df2008-05-17 18:14:43 +00007873- Patch #1700288: added a type attribute cache that caches method

7882 envvar and sys.dont_write_bytecode attribute. All these can be set
7883 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007884
Georg Brandl3ee81df2008-05-17 18:14:43 +00007885- Improve some exception messages when Windows fails to load an
7886 extension module. Now we get for example '%1 is not a valid Win32
7887 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007898- Compiler now generates simpler and faster code for dictionary
7899 literals. The oparg for BUILD_MAP now indicates an estimated
7900 dictionary size. There is a new opcode, STORE_MAP, for adding
7901 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007946 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7947 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007948
Georg Brandl3ee81df2008-05-17 18:14:43 +00007949- Issue #1686386: Tuple's tp_repr did not take into account the
7950 possibility of having a self-referential tuple, which is possible
7951 from C code. Nor did object's tp_str consider that a type's tp_str
7952 could do something that could lead to an inifinite recursion.
7953 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7954 issues.

7957 'print' statement to write to a file since the GIL was not released
7958 as needed. Now PyObject_Print() does the right thing along with
7959 various tp_print implementations of the built-in types and those in
7960 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007970 PyObject_Call() never calling back out to Python code to trigger
7971 recursion depth updates/checks. Required the creation of a static

8021
Guido van Rossum143b5642007-03-23 04:58:42 +00008022- Bug #1683368: The object.__init__() and object.__new__() methods are
8023 now stricter in rejecting excess arguments. The only time when
8024 either allows excess arguments is when it is not overridden and the
8025 other one is. For backwards compatibility, when both are
8026 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008027 warning later). Also, type.__init__() insists on the same signature
8028 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008030- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8031 object to complex using its __complex__() method before falling back
8032 to the __float__() method. Therefore, the functions in the cmath
8033 module now can operate on objects that define a __complex__()
8034 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008052- Bug #1678647: write a newline after printing an exception in any
8053 case, even when converting the value to a string failed.
8054
Georg Brandl871f1bc2007-03-12 13:17:36 +00008055- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008056 its argument, if it exists. If not, it will work like before. This
8057 allows customizing the output of dir() in the presence of a
8058 __getattr__().

8068 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008069
Georg Brandlaa2321b2007-03-07 00:40:28 +00008070- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008071 makes the filenames the warning module prints much more sensible
8072 when a PYTHONSTARTUP file is used.

8086 sq_ass_slice instead of the sq_slice slot.
8087
Georg Brandl3ee81df2008-05-17 18:14:43 +00008088- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00008641- Patch #1530482: add pydoc.render_doc() which returns the

8656
Georg Brandl92a6bae2007-03-13 17:43:32 +00008657- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008658 are set for invalid interpolation sequences that would lead to
8659 errors on reading back those values.

8715 TestCase and TestSuite subclasses (not instances) are no longer
8716 accepted in TestSuite.addTest(). This should cause no
8717 incompatibility since it never made sense with ordinary subclasses
8718 -- the failure just occurred later, with a more cumbersome
8719 exception.

Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008998
Georg Brandl3ee81df2008-05-17 18:14:43 +00008999- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009000 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00009002 does not claim to support starttls. Adds the
9003 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00009087

Georg Brandl3ee81df2008-05-17 18:14:43 +00009102 time so that opening a database previously created with the DB_DUP
9103 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9104 opens. Specifically: dictionary assignment to a DB object will
9105 replace all values for a given key when the database allows
9106 duplicate values. DB users should use DB.put(k, v) when they want
9107 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009108

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009395- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00009396 periodic threadstate and signal checking in tight loops. By
9397 default, this option is turned-off. It should only be enabled in
9398 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00009455
Georg Brandl3ee81df2008-05-17 18:14:43 +00009456- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9457 to ``PyTuple_SetItem``, it can be used to populate a brand new
9458 frozenset; but it does not steal a reference to the added item.

9470
Georg Brandl3ee81df2008-05-17 18:14:43 +00009471- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9472 of w# format code incorrectly truncated the length to an int, even
9473 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9474 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009475

Georg Brandl3ee81df2008-05-17 18:14:43 +00009504- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9505 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009506
Georg Brandl3ee81df2008-05-17 18:14:43 +00009507- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
