Mark Dickinsondbbed042011-09-19 16:38:08 +010044- Issue #12973: Fix overflow checks that invoked undefined behaviour in
45 int.__pow__. These overflow checks were causing int.__pow__ to produce
46 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010047 compiler optimizing the check away. Also fix similar overflow checks
48 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

294 and was unreliable since tests or user programs could modify the interpreter
295 environment after Distutils set it. Instead, have Distutils set the the
296 deployment target only in the environment of each build subprocess. It is
297 still possible to globally override the default by setting
298 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
299 greater or equal to the default value, the value with which the interpreter
300 was built.

1239 This prevents user-created self-referencing ordered dictionaries from
1240 becoming permanently uncollectable GC garbage. The downside is that
1241 removing __del__ means that the internal doubly-linked list has to wait for
1242 GC collection rather than freeing memory immediately when the refcnt drops
1243 to zero.

R. David Murray7c4bf552010-08-25 01:45:57 +00001274- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1275 character years even if the message contains RFC822 two character years.

1311 when the underlying raw IO channel was e.g. a socket. Report and original
1312 patch by Jason V. Miller.

1705 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

1718 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002063 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2064 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2065 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2086-----------------
2087
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002088- Issue #7301: Add environment variable $PYTHONWARNINGS.
2089
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002090- Issue #8329: Don't return the same lists from select.select when no fds are
2091 changed.
2092
Georg Brandlfee0f442010-05-22 21:26:21 +00002093- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002094 on 64-bit machines. The shift count for either left or right shift is
2095 permitted to be up to sys.maxsize.
2096
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002097- Ensure that tokenization of identifiers is not affected by locale.
2098
Georg Brandlfee0f442010-05-22 21:26:21 +00002099- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002100
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002101- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2102
Georg Brandlfee0f442010-05-22 21:26:21 +00002103- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2104 with a non-empty format string. This is an effort to future-proof user
2105 code. If a derived class does not currently implement __format__ but later
2106 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002107 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002108 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002109
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002110- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002123- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002124 (SIGINT). If an error occurs while importing the site module, the error is
2125 printed and Python exits. Initialize the GIL before importing the site

2140
Georg Brandlfee0f442010-05-22 21:26:21 +00002141- Issue #8257: The Decimal construct now accepts a float instance directly,
2142 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002143
2144 >>> Decimal(1.1)
2145 Decimal('1.100000000000000088817841970012523233890533447265625')
2146
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002147- collections.Counter() now supports a subtract() method.
2148
Georg Brandlfee0f442010-05-22 21:26:21 +00002149- The functools module now has a total_ordering() class decorator to simplify
2150 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002151
Georg Brandlfee0f442010-05-22 21:26:21 +00002152- The functools module also adds cmp_to_key() as a tool to transition old-style
2153 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002154
Georg Brandlfee0f442010-05-22 21:26:21 +00002155- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2156 directly.

Georg Brandlfee0f442010-05-22 21:26:21 +00002158- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2159 InvalidOperation instead of returning False. (Comparisons involving a quiet
2160 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2161 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002162
Georg Brandlfee0f442010-05-22 21:26:21 +00002163- Issue #2531: Comparison operations between floats and Decimal instances now
2164 return a result based on the numeric values of the operands; previously they
2165 returned an arbitrary result based on the relative ordering of id(float) and
2166 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002167
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002168- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002169 argument `-` which tells it to read files to compile from stdin. Each line is
2170 read on demand and the named file is compiled immediately. (Original patch by
2171 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002172

Florent Xicluna58b65662010-03-30 16:29:03 +00002176- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2177 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002178 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002179
Georg Brandlfee0f442010-05-22 21:26:21 +00002180- Comparisons using one of <, <=, >, >= between a complex instance and a
2181 Fractions instance now raise TypeError instead of returning True/False. This
2182 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2183 <=> complex, and complex <=> complex comparisons.

2292 the set of integer codes for which it was used differed between native packing
2293 and standard packing.)

2546 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2547 returning NULL. The macro now returns a statically allocated empty string
2548 instead.

2558 strings,
2559 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2560 numeric strings corresponding to subnormal values,

Antoine Pitroud840e512010-02-04 20:20:18 +00002593- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002594 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002600- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002601 file position when calling `truncate()`. It would previously change the file
2602 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002603 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2604
Georg Brandlba83f822010-03-14 09:50:54 +00002605- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2606 class used to represent files stored inside an archive. The new
2607 implementation is significantly faster and can be wrapped in a
2608 ``io.BufferedReader`` object for more speedups. It also solves an issue
2609 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2610 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002620- Issue #7748: Since unicode values are supported for some metadata options in
2621 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2622 encoded string for them. This ensures that the upload and register commands
2623 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002894- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2895 decimal string that's guaranteed to round back to x under correct rounding
2896 (with round-half-to-even rounding mode). Previously it gave a string based on
2897 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2898 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2899 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002900
Georg Brandlba83f822010-03-14 09:50:54 +00002901- Issue #7117: On almost all platforms: float-to-string and string-to-float
2902 conversions within Python are now correctly rounded. Places these conversions
2903 occur include: str for floats and complex numbers; the float and complex
2904 constructors; old-style and new-style numeric formatting; serialization and
2905 deserialization of floats and complex numbers using marshal, pickle and json;
2906 parsing of float and imaginary literals in Python code; Decimal-to-float
2907 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002908
Georg Brandlba83f822010-03-14 09:50:54 +00002909 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2910 providing correctly-rounded strtod and dtoa C functions. This code is
2911 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2912 the C compiler. There may be a small number of platforms on which correct
2913 operation of this code cannot be guaranteed, so the code is not used: notably,
2914 this applies to platforms where the C double format is not IEEE 754 binary64,
2915 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2916 and Python's configure script is unable to determine how to change the FPU
2917 precision. On these platforms conversions use the platform strtod and dtoa,
2918 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002920- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2921 uses the correctly-rounded string <-> float conversions described above (when
2922 available), and so produces correctly rounded results that will display nicely
2923 under the float repr. There are two related small changes: (1) round now
2924 accepts any class with an ``__index__()`` method for its second argument (but
2925 no longer accepts floats for the second argument), and (2) an excessively
2926 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2927 raises an exception.

3076 but with at least one decimal point and with a default precision
3077 of 12. Previously, the behavior the same but with a default precision of 6.
3078 This more closely matches ``str()``, and reduces surprises when adding

3306 this code path is really executed because I cannot move to such directory on
3307 win2k)

3333 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3334 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3335 of using the replace error handler in PyUnicode_DecodeUTF8().

Georg Brandlba83f822010-03-14 09:50:54 +00004550- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
4551 in the Lib/test directory, which might be read-only for the user running the
4552 tests.

Georg Brandlba83f822010-03-14 09:50:54 +00004566 leak-chasing test runs give sensible results. The previous method of reaping
4567 threads could return successfully while some Thread objects were still
4568 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004569
Georg Brandlba83f822010-03-14 09:50:54 +00004570- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer

4575
R. David Murray14dcd432009-10-14 13:58:07 +00004576- Issue #7058: Added save/restore for things like sys.argv and cwd to
4577 runtest_inner in regrtest, with warnings if the called test modifies them,
4578 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004585- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4586 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004587 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4588 the tests if DISPLAY is defined but can't be used.

4594 import both normal and optimised versions of modules. test_heapq and
4595 test_warnings have been adjusted to use it, tests for other modules with both
4596 C and Python implementations in the stdlib can be adjusted to use it over
4597 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004605- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4606 should cause a test to be skipped are now done using import_module from test
4607 support, which does the conversion.

4709
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004710- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4711 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4712 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4713 ``printf`` function, whereas PyString_FromFormat has an independent
4714 implementation and uses "%zd" on all platforms for size_t values.
4715 This makes a difference on win64, where ``printf`` needs "%Id" to display
4716 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00004718- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

4722 object; previously an int would be returned for small values. the __long__
4723 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00004735- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004736 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4737 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4738 when given a tuple of classes as second argument, were looking up
4739 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4740 type object.

4833-----------------
4834
Jesse Noller438195f2009-01-18 21:04:36 +00004835- Issue #4301: Patch the logging module to add processName support, remove
4836 _check_logger_class from multiprocessing.
4837
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004838- Issue #2975: When compiling several extension modules with Visual Studio 2008
4839 from the same python interpreter, some environment variables would grow
4840 without limit.
4841
Benjamin Peterson37346b22008-08-23 20:27:43 +00004842- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4843 exploitation of poor argument checking.
4844
Gerhard Häringef2276b2008-09-12 13:54:06 +00004845- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4846
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004847- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4848 remaining ones have "pysqlite_" prefix.
4849
Gerhard Häringe6872eb2008-09-12 22:33:22 +00004850- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

4858 wrapper for warnings.catch_warnings() that makes it easier to check
4859 that expected warning messages are being reported.
4860
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00004861- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004879What's New in Python 2.6 beta 3?
4880================================
4881
Barry Warsaw07a4a382008-08-21 01:15:08 +00004882*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004883
4884Core and Builtins
4885-----------------
4886
Guido van Rossumf8402962008-08-20 15:01:50 +00004887- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4888 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4889 extensions do not automatically benefit from the class attribute
4890 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4891 to their tp_flags field if they care. This is a backwards
4892 compatibility feature; in 3.0, all types will use the cache by
4893 default.
4894
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004895- Keyword arguments can now follow starred arguments. (``f(a, *args,
4896 keyword=23)`` is now valid syntax.)
4897
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004898- ctypes function pointers that are COM methods have a boolean True
4899 value again.
4900
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004901- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4902 by denying s# to parse objects that have a releasebuffer procedure,
4903 and introducing s*.
4904
Georg Brandl1e13ea92008-08-11 09:07:59 +00004905- Issue #3537: Fix an assertion failure when an empty but presized dict
4906 object was stored in the freelist.
4907
Mark Dickinsonb6467572008-08-04 21:30:09 +00004908- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4909 ValueError consistently across platforms.
4910
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004911- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4912 (64bit Unix, for example), unichr() would truncate its argument and return
4913 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4914
Neal Norwitze7d8be82008-07-31 17:17:14 +00004915- Apply security patches from Apple.
4916
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004917- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4918 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4919
Antoine Pitrou92f82162008-07-25 22:22:08 +00004920- Issue #1819: function calls with several named parameters are now on
4921 average 35% faster (as measured by pybench).
4922
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004923- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4924 the python debugger steps into a class statement: the free variables (local
4925 variables defined in an outer scope) would be deleted from the outer scope.
4926
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004927- Issue #2620: Overflow checking when allocating or reallocating memory
4928 was not always being done properly in some python types and extension
4929 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4930 all been updated to perform better checks and places in the code that
4931 would previously leak memory on the error path when such an allocation
4932 failed have been fixed.
4933
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004934Library
4935-------
4936
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004937- Issue #3612: Added some missing basic types in ctypes.wintypes.
4938
Benjamin Petersone977ad42008-08-20 01:42:01 +00004939- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4940 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4941
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004942- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4943 version reported by these tools does not necessarily follow the python
4944 version numbering scheme, so the module is less strict when parsing it.
4945
Nick Coghlanf70385a2008-08-18 12:42:46 +00004946- Issue #2235: Added Py3k warnings for types which will become unhashable
4947 under the stricter __hash__ inheritance rules in 3.0. Several types
4948 which did not meet the rules for hash invariants and were already
4949 unhashable in 3.0 have now been explicitly flagged as unhashable in
4950 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4951 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4952
Brett Cannon88f801d2008-08-18 00:46:22 +00004953- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4954 imported into the module but exposed as part of the module's API.
4955
Brett Cannon7b96f072008-08-18 00:41:11 +00004956- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4957
Brett Cannon46225e72008-08-18 00:36:52 +00004958- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4959
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004960- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4961
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004962- Issue #3575: Incremental decoder's decode function now takes bytearray
4963 by using 's*' instead of 't#'.
4964
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004965- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004966 fails unicode conversion on 2nd parameter. (windows only)
4967
Georg Brandl222e2082010-08-01 22:27:39 +00004968- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004969 in a redirect.
4970
Brett Cannonabe423e2008-08-16 21:47:07 +00004971- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004972 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004973
Facundo Batistaeb90b782008-08-16 14:44:07 +00004974- Issue #2776: fixed small issue when handling an URL with double slash
4975 after a 302 response in the case of not going through a proxy.
4976
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004977- Issue #2676: in the email package, content-type parsing was hanging on
4978 pathological input because of quadratic or exponential behaviour of a
4979 regular expression.
4980
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004981- Issue #3476: binary buffered reading through the new "io" library is now
4982 thread-safe.
4983
Brett Cannonbf3157b2008-08-14 05:00:03 +00004984- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4985 since mimetools itself is deprecated. Because modules are cached, all
4986 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4987
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004988- Issue #3134: shutil referenced undefined WindowsError symbol.
4989
Robert Schuppenies14646332008-08-10 11:01:53 +00004990- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4991 menu entries were not deleted.
4992
Brett Cannon83e81842008-08-09 23:30:55 +00004993- Copied the implementation of reduce() to _functools.reduce() to have a
4994 version that did not raise a DeprecationWarning under -3.
4995
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004996- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4997 a MemoryError rather than silently stop the iteration.
4998
Guido van Rossum59ce9012008-08-09 14:55:34 +00004999- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5000 to _sre.compile() will now be rejected. This should not affect anybody
5001 since the re.compile() function never generates invalid re-bytecode.
5002
Skip Montanaroa032bf42008-08-08 22:52:51 +00005003- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5004 upon first access it can be automatically initialized from the csv file if
5005 it wasn't initialized during instantiation.
5006
Brett Cannon3aa2a492008-08-06 22:28:09 +00005007- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5008 the reload() built-in has been removed.
5009
Brett Cannon7e30b672008-08-04 21:52:25 +00005010- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005011 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005012 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5013 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5014 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5015 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5016 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005017
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005018- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5019 raised an AttributeError.
5020
Benjamin Peterson01a24322008-07-28 23:35:27 +00005021- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005022 asking for a specific length. This problem only affected files opened
5023 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005024
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005025- Issue #3449: Update decimal module to use most recent specification
5026 (v. 1.68) and tests (v. 2.58) from IBM.
5027
Georg Brandl222e2082010-08-01 22:27:39 +00005028- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

5032
Georg Brandlf9efabb2008-07-23 15:16:45 +00005033- Deprecate the "ast" parser function aliases.
5034
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005035- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5036
5037- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5038 invalid arguments.
5039
5040- Issue #3302: Fix several crashes when calling locale's gettext functions
5041 with None arguments.
5042
5043- Issue #3389: Allow resolving dotted names for handlers in logging
5044 configuration files.
5045

5047
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005048- Issue #3394: zipfile.writestr sets external attributes when passed a
5049 file name rather than a ZipInfo instance, so files are extracted with
5050 mode 0600 rather than 000 under Unix.
5051
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005052- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5053 argument in python 2.5, this broke code that subclassed Popen to include its
5054 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5062-------------
5063
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005064- Issue #2235: the C API function PyObject_HashNotImplemented and its
5065 interaction with the tp_hash slot (added in 2.6b2) are now documented
5066
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005067- Issue #643841: The language reference now provides more detailed
5068 coverage of the lookup process for special methods. The disclaimers
5069 regarding lack of coverage of new-style classes have also been
5070 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005073What's New in Python 2.6 beta 2?
5074================================
5075
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005076*Release date: 17-Jul-2008*
5077
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005078Core and Builtins
5079-----------------
5080
Georg Brandl3e483f62008-07-16 22:57:41 +00005081- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5082 its methods now allow for items objects that can be converted to
5083 an integer using operator.index().
5084
Mark Dickinson64b7e502008-07-16 09:40:03 +00005085- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5086 produced a ValueError instead of giving the correct float.
5087
Eric Smitha5fa5a22008-07-16 00:11:49 +00005088- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5089 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5090
Mark Dickinson7103aa42008-07-15 19:08:33 +00005091- Issue #3008: the float type has a new instance method 'float.hex'
5092 and a new class method 'float.fromhex' to convert floating-point
5093 numbers to and from hexadecimal strings, respectively.
5094
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005095- Issue #2235: __hash__ is once again inherited by default. To allow
5096 collections.Hashable to remain meaningful in the presence of the
5097 default hash implementation (object.__hash__), it is now possible
5098 to explicit block inheritance of hash by setting __hash__=None at
5099 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5100 level.
5101
Nick Coghlanb028f502008-07-13 14:52:36 +00005102- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5103 the parent module cannot be found while performing an absolute import.
5104 This means that an incorrectly defined __package__ attribute will
5105 now only prevent relative imports in that module rather than causing
5106 all imports from that module to fail.
5107
Nick Coghlan14ff9942008-07-08 14:21:42 +00005108- Issue #2517: Allow unicode messages in Exceptions again by correctly
5109 bypassing the instance dictionary when looking up __unicode__ on
5110 new-style classes.
5111
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005112- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5113 set to a custom object whose write() method happens to install
5114 another file in sys.stdout.
5115
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005116- Issue #3088: Corrected a race condition in classes derived from
5117 threading.local: the first member set by a thread could be saved in
5118 another thread's dictionary.
5119
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005120- Issue #3004: Minor change to slice.indices(): the start and stop
5121 arguments are now treated identically, making the behaviour easier
5122 to describe and understand. For example, slice(None, -10,
5123 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5124 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00005579 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005580
5581 This is controlled by the configure argument ``--with-universal-archs``:
5582
5583 - ``--with-universal-archs=all``: install 4-way universal
5584
5585 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5586
5587 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5588

5628 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00005629
Christian Heimese74c8f22008-04-19 02:23:57 +00005630- Added kill, terminate and send_signal(sig) to subprocess.Popen.
5631

Georg Brandl3ee81df2008-05-17 18:14:43 +00005641- Issue #1631171: Re-implement the 'warnings' module in C (the
5642 original Python code has been kept as backup). This will allow for
5643 using the 'warning's machinery in such places as the parser where
5644 use of pure Python code is not possible. Both the ``showarning()``
5645 and ``formatwarning()`` gain an optional 'line' argument which is
5646 not called by default for backwards-compatibility reasons. Setting
5647 ``warnings.showwarning()`` to an implementation that lacks support
5648 for the ``line`` argument will raise a DeprecationWarning.

5672
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00005673- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00005711- Issue #2550: The approach used by client/server code for obtaining
5712 ports to listen on in network-oriented tests has been refined in an
5713 effort to facilitate running multiple instances of the entire
5714 regression test suite in parallel without issue.
5715 test_support.bind_port() has been fixed such that it will always
5716 return a unique port -- which wasn't always the case with the
5717 previous implementation, especially if socket options had been set
5718 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5719 new implementation of bind_port() will actually raise an exception
5720 if it is passed an AF_INET/SOCK_STREAM socket with either the
5721 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5722 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5723 the socket it's been passed. This currently only applies to
5724 Windows. This option prevents any other sockets from binding to the
5725 host/port we've bound to, thus removing the possibility of the
5726 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5727 when a second SOCK_STREAM socket binds and accepts to a host/port
5728 that's already been bound by another socket. The optional preferred
5729 port parameter to bind_port() has been removed. Under no
5730 circumstances should tests be hard coding ports!
5731
5732 test_support.find_unused_port() has also been introduced, which will
5733 pass a temporary socket object to bind_port() in order to obtain an
5734 unused port. The temporary socket object is then closed and
5735 deleted, and the port is returned. This method should only be used
5736 for obtaining an unused port in order to pass to an external program
5737 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5738 a parameter to a server-oriented class that doesn't give you direct
5739 access to the underlying socket used.
5740
5741 Finally, test_support.HOST has been introduced, which should be used
5742 for the host argument of any relevant socket calls (i.e. bind and
5743 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005744
5745 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005746 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005747 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5748 test_asynchat and test_socket_ssl.
5749
Georg Brandl3ee81df2008-05-17 18:14:43 +00005750 It is now possible for multiple instances of the regression test
5751 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006030- Added the future_builtins module, which contains hex() and oct().
6031 These are the PEP 3127 version of these functions, designed to be
6032 compatible with the hex() and oct() builtins from Python 3.0. They
6033 differ slightly in their output formats from the existing, unchanged
6034 Python 2.6 builtins. The expected usage of the future_builtins
6035 module is:
6036 from future_builtins import hex, oct
6037
Eric Smith7ef40bf2008-02-20 23:34:22 +00006038- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6039 exponents for exponents with absolute value < 100. Follows C99
6040 standard. This is a change on Windows, which would use 3 digits.
6041 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6042 so that any alterations it does to the resulting string will be
6043 available in stringlib/formatter.h (for float.__format__).
6044
Eric Smith5a3c1352008-02-19 13:21:56 +00006045- Implemented PEP 3101, Advanced String Formatting. This adds a new
6046 builtin format(); a format() method for str and unicode; a
6047 __format__() method to object, str, unicode, int, long, float, and
6048 datetime; the class string.Formatter; and the C API
6049 PyObject_Format().
6050
Georg Brandl3ee81df2008-05-17 18:14:43 +00006051- Fixed several potential crashes, all caused by specially crafted
6052 __del__ methods exploiting objects in temporarily inconsistent
6053 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006054
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006055- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006056 prevent a possible crash: an Abstract Base Class would try to access
6057 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006062- Clear all free lists during a gc.collect() of the highest generation
6063 in order to allow pymalloc to free more arenas. Python may give back
6064 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006065
Georg Brandl3ee81df2008-05-17 18:14:43 +00006066- Issue #2045: Fix an infinite recursion triggered when printing a
6067 subclass of collections.defaultdict, if its default_factory is set
6068 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006069
Christian Heimesf75dbef2008-02-08 00:11:31 +00006070- Fixed a minor memory leak in dictobject.c. The content of the free
6071 list was not freed on interpreter shutdown.
6072
Georg Brandl21e99f42010-03-07 15:23:59 +00006073- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006074 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006075
Georg Brandl3ee81df2008-05-17 18:14:43 +00006076- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6077 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006078 to compact the internal free lists of pre-allocted ints and floats.
6079
Georg Brandl3ee81df2008-05-17 18:14:43 +00006080- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6081 calls. Python expected the return type int but the fork familie
6082 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006083
Georg Brandl3ee81df2008-05-17 18:14:43 +00006084- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6085 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006086

Georg Brandl3ee81df2008-05-17 18:14:43 +00006096- Patch #1473257: generator objects gain a gi_code attribute. This is
6097 the same object as the func_code attribute of the function that
6098 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006099
Georg Brandl3ee81df2008-05-17 18:14:43 +00006100- Issue #1920: "while 0" statements were completely removed by the
6101 compiler, even in the presence of an "else" clause, which is
6102 supposed to be run when the condition is false. Now the compiler
6103 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006104
Guido van Rossumeead05f2008-01-24 18:21:02 +00006105- A few crashers fixed: weakref_in_del.py (issue #1377858);
6106 loosing_dict_ref.py (issue #1303614, test67.py);
6107 borrowed_ref_[34].py (not in tracker).
6108
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006109- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006110 suppressed while an extension is loaded by calling SetErrorMode in
6111 dynload_win.c. The error is still reported properly.
6112
Georg Brandl3ee81df2008-05-17 18:14:43 +00006113- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006114 several extension methods and modules do not work without unicode
6115 support.
6116
Georg Brandl26543b12008-01-21 18:36:51 +00006117- Issue #1882: when compiling code from a string, encoding cookies in the
6118 second line of code were not always recognized correctly.
6119
Georg Brandl14404b62008-01-19 19:27:05 +00006120- Issue #1679: "0x" was taken as a valid integer literal.
6121
Georg Brandl6caad7d2008-01-26 14:19:22 +00006122- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006123 added.
6124
Christian Heimesc94e2b52008-01-14 04:13:37 +00006125- sys.float_info / PyFloat_GetInfo: The floating point information
6126 object was converted from a dict to a specialized structseq object.
6127
Georg Brandl3ee81df2008-05-17 18:14:43 +00006128- Patch #1816: Added sys.flags structseq. It exposes the status of
6129 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006130
Georg Brandl3ee81df2008-05-17 18:14:43 +00006131- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00006192- Patch #1739468: Directories and zipfiles containing a __main__.py
6193 file can now be directly executed by passing their name to the
6194 interpreter. The directory/zipfile is automatically inserted as the
6195 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006197- Issue #1265: Fix a problem with sys.settrace, if the tracing
6198 function uses a generator expression when at the same time the
6199 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006200
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006201- sets and frozensets now have an isdisjoint() method.

6206
Georg Brandl21e99f42010-03-07 15:23:59 +00006207- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006208 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6209 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006210
Georg Brandl3ee81df2008-05-17 18:14:43 +00006211- Issue #1686386: Tuple's tp_repr did not take into account the
6212 possibility of having a self-referential tuple, which is possible
6213 from C code. Nor did object's tp_str consider that a type's tp_str
6214 could do something that could lead to an inifinite recursion.
6215 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6216 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006217
Georg Brandl3ee81df2008-05-17 18:14:43 +00006218- Issue #1164: It was possible to trigger deadlock when using the
6219 'print' statement to write to a file since the GIL was not released
6220 as needed. Now PyObject_Print() does the right thing along with
6221 various tp_print implementations of the built-in types and those in
6222 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006223
Georg Brandl3ee81df2008-05-17 18:14:43 +00006224- Issue #1147: Exceptions were directly allowing string exceptions in

6226 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00006230
Brett Cannon1e534b52007-09-07 04:18:30 +00006231- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006232 PyObject_Call() never calling back out to Python code to trigger
6233 recursion depth updates/checks. Required the creation of a static
6234 RuntimeError instance in case normalizing an exception put the
6235 recursion check value past its limit. Fixes crashers
6236 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00006251- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006252 __*__ attributes. (Some already existed, e.g., __doc__ and
6253 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006254
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006255- Add -3 option to the interpreter to warn about features that are
6256 deprecated and will be changed/removed in Python 3.0.
6257
Georg Brandl2134e752007-05-21 20:34:16 +00006258- Patch #1686487: you can now pass any mapping after '**' in function
6259 calls.
6260
Collin Winter62903052007-05-18 23:11:24 +00006261- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006262 "except E as target:". This is to provide forwards compatibility
6263 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006270- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006271 setting a plain string, ie don't expand to single letter identifiers.
6272
Raymond Hettinger13936692007-04-11 18:40:58 +00006273- Request #1191699: Slices can now be pickled.
6274
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006275- Request #1193128: str.translate() now allows a None argument for

6277 remaining characters.
6278
Georg Brandl5cb76c12007-03-21 09:00:39 +00006279- Patch #1682205: a TypeError while unpacking an iterable is no longer

6283
Guido van Rossum143b5642007-03-23 04:58:42 +00006284- Bug #1683368: The object.__init__() and object.__new__() methods are
6285 now stricter in rejecting excess arguments. The only time when
6286 either allows excess arguments is when it is not overridden and the
6287 other one is. For backwards compatibility, when both are
6288 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006289 warning later). Also, type.__init__() insists on the same signature
6290 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006291
Georg Brandl3ee81df2008-05-17 18:14:43 +00006292- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6293 object to complex using its __complex__() method before falling back
6294 to the __float__() method. Therefore, the functions in the cmath
6295 module now can operate on objects that define a __complex__()
6296 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006297
Georg Brandl3ee81df2008-05-17 18:14:43 +00006298- Patch #1623563: allow __class__ assignment for classes with

6300 same slot names.

6307 its type.

6313
Georg Brandl7b9c5552007-03-12 14:30:05 +00006314- Bug #1678647: write a newline after printing an exception in any
6315 case, even when converting the value to a string failed.
6316
Georg Brandl871f1bc2007-03-12 13:17:36 +00006317- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006318 its argument, if it exists. If not, it will work like before. This
6319 allows customizing the output of dir() in the presence of a
6320 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006328- Patch #1491866: change the complex() constructor to allow
6329 parthensized forms. This means complex(repr(x)) now works instead of
6330 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006331
Georg Brandlaa2321b2007-03-07 00:40:28 +00006332- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006333 makes the filenames the warning module prints much more sensible
6334 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006335

Georg Brandl0fca97a2007-03-05 22:28:08 +00006347- Patch #1674228: when assigning a slice (old-style), check for the
6348 sq_ass_slice instead of the sq_slice slot.
6349
Georg Brandl3ee81df2008-05-17 18:14:43 +00006350- When printing an unraisable error, don't print exceptions. before
6351 the name. This duplicates the behavior whening normally printing
6352 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006920 are set for invalid interpolation sequences that would lead to

6977 TestCase and TestSuite subclasses (not instances) are no longer
6978 accepted in TestSuite.addTest(). This should cause no

6980 -- the failure just occurred later, with a more cumbersome
6981 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007262- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7263 with RFC 3207 and forgets any knowledge obtained from the server not
7264 obtained from the TLS negotiation itself. Patch contributed by Bill
7265 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007266
Georg Brandl3ee81df2008-05-17 18:14:43 +00007267- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007268 that the SMTP.starttls() caller no longer needs to call ehlo()
7269 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007270 does not claim to support starttls. Adds the
7271 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7272 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007326- itertools.chain() now has an alternate constructor,

7352 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7353 silently miscode subclasses of those types. Now, it raises a
7354 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007355

Georg Brandl3ee81df2008-05-17 18:14:43 +00007370 time so that opening a database previously created with the DB_DUP
7371 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7372 opens. Specifically: dictionary assignment to a DB object will
7373 replace all values for a given key when the database allows
7374 duplicate values. DB users should use DB.put(k, v) when they want
7375 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007376

7382 characters with ASCII value less than 32. Also, it correctly quotes
7383 dots only if they occur on a single line, as opposed to the previous
7384 behavior of quoting dots if they are the second character of any
7385 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007386

Guido van Rossum7c862f82007-12-13 20:50:10 +00007648- Bug #1608: use -fwrapv when GCC supports it. This is important,
7649 newer GCC versions may optimize away overflow buffer overflow checks
7650 without this option!

Martin v. Löwis63bf1492007-11-12 05:14:05 +00007652- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
7653
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00007654- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00007655 periodic threadstate and signal checking in tight loops. By
7656 default, this option is turned-off. It should only be enabled in
7657 debugged, performance critical applications.

7673 returned by python-config if Python was built with --enable-shared
7674 because that prevented the shared library from being used.

7708-----
7709
Georg Brandl3ee81df2008-05-17 18:14:43 +00007710- Unified naming convention for free lists and their limits. All free
7711 lists in Object/ are named ``free_list``, the counter ``numfree``
7712 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
7713 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00007714
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7716 to ``PyTuple_SetItem``, it can be used to populate a brand new
7717 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00007718

7726
7727- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
7728 ``PyFloat_GetInfo()`` to the float API.
7729
Georg Brandl3ee81df2008-05-17 18:14:43 +00007730- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7731 of w# format code incorrectly truncated the length to an int, even
7732 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7733 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007734
Georg Brandl3ee81df2008-05-17 18:14:43 +00007735- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7753- Fix some leftovers from the conversion from int to Py_ssize_t
7754 (relevant to strings and sequences of more than 2**31 items).
7755
7756- Make _PyGILState_NoteThreadState() static, it was not used anywhere
7757 outside of pystate.c and should not be necessary.
7758
Georg Brandl3ee81df2008-05-17 18:14:43 +00007759- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
7760 absolute imports. In earlier versions they might have used relative
7761 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00007762
Georg Brandl3ee81df2008-05-17 18:14:43 +00007763- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7764 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007765
Georg Brandl3ee81df2008-05-17 18:14:43 +00007766- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

7774 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
7775 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
7776 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007777

Georg Brandl3ee81df2008-05-17 18:14:43 +00007791- Removed the macfs module. It had been deprecated since Python 2.5.
7792 This lead to the deprecation of macostools.touched() as it relied
7793 solely on macfs and was a no-op under OS X.
