12Core and Builtins
13-----------------
14
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +000015- Issue #8748: Fix two issues with comparisons between complex and integer
16 objects. (1) The comparison could incorrectly return True in some cases
17 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
18 (2) The comparison raised an OverflowError for large integers, leading
19 to unpredictable exceptions when combining integers and complex objects
20 in sets or dicts.
21
Mark Dickinson81336372010-05-30 12:12:25 +000022- Issue #5211: Implicit coercion for the complex type is now completely
23 removed. (Coercion for arithmetic operations was already removed in 2.7
24 alpha 4, but coercion for rich comparisons was accidentally left in.)
25
Victor Stinnerc49dfcc2010-05-25 22:30:32 +000026- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
27 and error handler, instead of writing to the C stderr file in utf-8
28
Georg Brandlfee0f442010-05-22 21:26:21 +000029- Issue #7902: When using explicit relative import syntax, don't try implicit
30 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +000031
Georg Brandlfee0f442010-05-22 21:26:21 +000032- Issue #7079: Fix a possible crash when closing a file object while using it
33 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +000034
Ronald Oussoren27c72e92010-06-02 03:47:14 +000035- Issue #8868: Fix that ensures that python scripts have access to the
36 Window Server again in a framework build on MacOSX 10.5 or earlier.

39-----
40
Georg Brandlfee0f442010-05-22 21:26:21 +000041- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
42 of the interpreter to set sys.argv without also modifying sys.path. This
43 helps fix `CVE-2008-5983
Antoine Pitrou6a265602010-05-21 17:12:38 +000044 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.

51
Lars Gustäbel2ee9c6f2010-06-03 09:56:22 +000052- Issue #8833: tarfile created hard link entries with a size field != 0 by
53 mistake.
54
R. David Murray52dcd452010-06-02 22:03:15 +000055- Issue #1368247: set_charset (and therefore MIMEText) now automatically
56 encodes a unicode _payload to the output_charset.
57
Alexander Belopolsky9292ee02010-05-27 20:55:27 +000058- Issue #7150: Raise OverflowError if the result of adding or subtracting

115
Georg Brandlfee0f442010-05-22 21:26:21 +0000116- On darwin, ``test_site`` assumed that a framework build was being used,
117 leading to a failure where four directories were expected for site-packages

137 non-float non-integer argument is now converted to an integer (if possible)
138 using its __int__ method. Previously, only small arguments were treated this
139 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +0000148 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +0000149 benefit compared to the dynamic memory allocation fallback. Patch by
150 Charles-François Natali.

191 operation raises multiple signals and more than one of those signals is
192 trapped, the specification determines the order in which the signals should be
193 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +0000257- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
258 string "python" as the *ident*. openlog() arguments are all optional and
259 keywords.

Georg Brandlfee0f442010-05-22 21:26:21 +0000292 filename and date, conforming to the 'standards' they were originally designed
293 to follow. This improves compatibility with patch tools.
R. David Murray1a14d3d2010-04-12 16:35:19 +0000294
R. David Murray27ef9372010-04-12 14:26:06 +0000295- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
Georg Brandlfee0f442010-05-22 21:26:21 +0000296 character sets will now consistently use a Content-Transfer-Encoding of 7bit

312
Georg Brandlfee0f442010-05-22 21:26:21 +0000313- On Windows, ctypes does no longer check the stack before and after calling a
314 foreign function. This allows to use the unmodified libffi library.

Georg Brandlfee0f442010-05-22 21:26:21 +0000338- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000339 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
340 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
341 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

361Core and Builtins
362-----------------
363
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000364- Issue #7301: Add environment variable $PYTHONWARNINGS.
365
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000366- Issue #8329: Don't return the same lists from select.select when no fds are
367 changed.
368
Georg Brandlfee0f442010-05-22 21:26:21 +0000369- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000370 on 64-bit machines. The shift count for either left or right shift is
371 permitted to be up to sys.maxsize.
372
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000373- Ensure that tokenization of identifiers is not affected by locale.
374
Georg Brandlfee0f442010-05-22 21:26:21 +0000375- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000377- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
378
Georg Brandlfee0f442010-05-22 21:26:21 +0000379- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
380 with a non-empty format string. This is an effort to future-proof user
381 code. If a derived class does not currently implement __format__ but later
382 adds its own __format__, it would most likely break user code that had
383 supplied a format string. This will be changed to a DeprecationWaring in
384 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000385
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000386- Issue #8268: Old-style classes (not just instances) now support weak
387 references.

410
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000411- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000412 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
413 `ssl.OPENSSL_VERSION_NUMBER`.

416
Georg Brandlfee0f442010-05-22 21:26:21 +0000417- Issue #8257: The Decimal construct now accepts a float instance directly,
418 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000419
420 >>> Decimal(1.1)
421 Decimal('1.100000000000000088817841970012523233890533447265625')
422
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000423- collections.Counter() now supports a subtract() method.
424
Georg Brandlfee0f442010-05-22 21:26:21 +0000425- The functools module now has a total_ordering() class decorator to simplify
426 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000427
Georg Brandlfee0f442010-05-22 21:26:21 +0000428- The functools module also adds cmp_to_key() as a tool to transition old-style
429 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000430
Georg Brandlfee0f442010-05-22 21:26:21 +0000431- Issue #8294: The Fraction constructor now accepts Decimal and float instances
432 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000433
Georg Brandlfee0f442010-05-22 21:26:21 +0000434- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
435 InvalidOperation instead of returning False. (Comparisons involving a quiet
436 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
437 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000438
Georg Brandlfee0f442010-05-22 21:26:21 +0000439- Issue #2531: Comparison operations between floats and Decimal instances now
440 return a result based on the numeric values of the operands; previously they
441 returned an arbitrary result based on the relative ordering of id(float) and
442 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000443
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000444- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000445 argument `-` which tells it to read files to compile from stdin. Each line is
446 read on demand and the named file is compiled immediately. (Original patch by
447 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000448
Georg Brandlfee0f442010-05-22 21:26:21 +0000449- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Georg Brandlfee0f442010-05-22 21:26:21 +0000456- Comparisons using one of <, <=, >, >= between a complex instance and a
457 Fractions instance now raise TypeError instead of returning True/False. This
458 makes Fraction <=> complex comparisons consistent with int <=> complex, float
459 <=> complex, and complex <=> complex comparisons.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000470- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000471 didn't support chflags() (for example ZFS under FreeBSD). The error is now
472 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000473
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000474- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000866- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000867 file position when calling `truncate()`. It would previously change the file
868 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000869 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Benjamin Petersone06f7112010-01-28 02:15:02 +0000871- UserDict is now a new-style class.
872
Georg Brandlba83f822010-03-14 09:50:54 +0000873- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
874 class used to represent files stored inside an archive. The new
875 implementation is significantly faster and can be wrapped in a
876 ``io.BufferedReader`` object for more speedups. It also solves an issue
877 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
878 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +0000888- Issue #7748: Since unicode values are supported for some metadata options in
889 Distutils, the DistributionMetadata get_* methods will now return an utf-8
890 encoded string for them. This ensures that the upload and register commands
891 send the correct values to PyPI without any error.

967
Georg Brandlba83f822010-03-14 09:50:54 +0000968- The ``__complex__()`` method is now looked up on the class of instances to
969 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000971- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
972 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
973
Mark Dickinson1b34d252010-01-01 17:27:30 +0000974- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000975 DeprecationWarning when passed a float argument where an integer was expected.
976 These functions and methods now raise TypeError instead. The majority of the
977 effects of this change are in the extension modules, but some core functions
978 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
979 and many unicode/str methods.

993 of integers: the result of a/b is now correctly rounded for ints a and b (at

Georg Brandlba83f822010-03-14 09:50:54 +00001162- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1163 decimal string that's guaranteed to round back to x under correct rounding
1164 (with round-half-to-even rounding mode). Previously it gave a string based on
1165 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1166 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1167 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001168
Georg Brandlba83f822010-03-14 09:50:54 +00001169- Issue #7117: On almost all platforms: float-to-string and string-to-float
1170 conversions within Python are now correctly rounded. Places these conversions
1171 occur include: str for floats and complex numbers; the float and complex
1172 constructors; old-style and new-style numeric formatting; serialization and
1173 deserialization of floats and complex numbers using marshal, pickle and json;
1174 parsing of float and imaginary literals in Python code; Decimal-to-float
1175 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001176
Georg Brandlba83f822010-03-14 09:50:54 +00001177 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1178 providing correctly-rounded strtod and dtoa C functions. This code is
1179 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1180 the C compiler. There may be a small number of platforms on which correct
1181 operation of this code cannot be guaranteed, so the code is not used: notably,
1182 this applies to platforms where the C double format is not IEEE 754 binary64,
1183 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1184 and Python's configure script is unable to determine how to change the FPU
1185 precision. On these platforms conversions use the platform strtod and dtoa,
1186 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001188- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1189 uses the correctly-rounded string <-> float conversions described above (when
1190 available), and so produces correctly rounded results that will display nicely
1191 under the float repr. There are two related small changes: (1) round now
1192 accepts any class with an ``__index__()`` method for its second argument (but
1193 no longer accepts floats for the second argument), and (2) an excessively
1194 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1195 raises an exception.

1344 but with at least one decimal point and with a default precision
1345 of 12. Previously, the behavior the same but with a default precision of 6.
1346 This more closely matches ``str()``, and reduces surprises when adding

1348 complex.__format__ in the same way.

1545
Georg Brandlba83f822010-03-14 09:50:54 +00001546- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1547 file objects with closefd=False. The file descriptor is still kept open but
1548 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00001572- On windows, ``os.chdir()`` given unicode was not working if
1573 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1574 this code path is really executed because I cannot move to such directory on
1575 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001577- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1578 element is temporarily replaced with an equivalent frozenset. But the
1579 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00001600- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1601 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1602 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1603 of using the replace error handler in PyUnicode_DecodeUTF8().
1604
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001605- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001608- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1610 gives improved memory leak detection when running under Valgrind, while taking
1611 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00002143- Issue #5679: The methods unittest.TestCase.addCleanup and doCleanups were
2144 added. addCleanup allows you to add cleanup functions that will be called
Michael Foord07ef4872009-05-02 22:43:34 +00002145 unconditionally (after setUp if setUp fails, otherwise after tearDown). This
2146 allows for much simpler resource allocation and deallocation during tests.

Michael Foord345b2fe2009-04-02 03:20:38 +00002161 and assertFalse messages are now useful. TestCase has a longMessage attribute.
2162 This defaults to False, but if set to True useful error messages are shown in
2163 addition to explicit messages passed to assert methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002834 leak-chasing test runs give sensible results. The previous method of reaping
2835 threads could return successfully while some Thread objects were still
2836 referenced. This also introduces a new private function: ``thread._count()``.

2854 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002855 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2856 the tests if DISPLAY is defined but can't be used.

2862 import both normal and optimised versions of modules. test_heapq and

2874 should cause a test to be skipped are now done using import_module from test
2875 support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002978- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2979 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2980 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2981 ``printf`` function, whereas PyString_FromFormat has an independent
2982 implementation and uses "%zd" on all platforms for size_t values.
2983 This makes a difference on win64, where ``printf`` needs "%Id" to display
2984 64bit values.

2990 object; previously an int would be returned for small values. the __long__

Antoine Pitrou0668c622008-08-26 22:42:08 +00003004 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3005 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3006 when given a tuple of classes as second argument, were looking up
3007 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3008 type object.

3126 wrapper for warnings.catch_warnings() that makes it easier to check
3127 that expected warning messages are being reported.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003147What's New in Python 2.6 beta 3?
3148================================
3149
Barry Warsaw07a4a382008-08-21 01:15:08 +00003150*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003151
3152Core and Builtins
3153-----------------
3154
Guido van Rossumf8402962008-08-20 15:01:50 +00003155- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3156 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3157 extensions do not automatically benefit from the class attribute
3158 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3159 to their tp_flags field if they care. This is a backwards
3160 compatibility feature; in 3.0, all types will use the cache by
3161 default.
3162
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003163- Keyword arguments can now follow starred arguments. (``f(a, *args,
3164 keyword=23)`` is now valid syntax.)
3165
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003166- ctypes function pointers that are COM methods have a boolean True
3167 value again.
3168
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003169- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3170 by denying s# to parse objects that have a releasebuffer procedure,
3171 and introducing s*.
3172
Georg Brandl1e13ea92008-08-11 09:07:59 +00003173- Issue #3537: Fix an assertion failure when an empty but presized dict
3174 object was stored in the freelist.
3175
Mark Dickinsonb6467572008-08-04 21:30:09 +00003176- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3177 ValueError consistently across platforms.
3178
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003179- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3180 (64bit Unix, for example), unichr() would truncate its argument and return
3181 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3182
Neal Norwitze7d8be82008-07-31 17:17:14 +00003183- Apply security patches from Apple.
3184
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003185- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3186 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3187
Antoine Pitrou92f82162008-07-25 22:22:08 +00003188- Issue #1819: function calls with several named parameters are now on
3189 average 35% faster (as measured by pybench).
3190
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003191- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3192 the python debugger steps into a class statement: the free variables (local
3193 variables defined in an outer scope) would be deleted from the outer scope.
3194
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003195- Issue #2620: Overflow checking when allocating or reallocating memory
3196 was not always being done properly in some python types and extension
3197 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3198 all been updated to perform better checks and places in the code that
3199 would previously leak memory on the error path when such an allocation
3200 failed have been fixed.
3201
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003202Library
3203-------
3204
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003205- Issue #3612: Added some missing basic types in ctypes.wintypes.
3206
Benjamin Petersone977ad42008-08-20 01:42:01 +00003207- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3208 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3209
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003210- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3211 version reported by these tools does not necessarily follow the python
3212 version numbering scheme, so the module is less strict when parsing it.
3213
Nick Coghlanf70385a2008-08-18 12:42:46 +00003214- Issue #2235: Added Py3k warnings for types which will become unhashable
3215 under the stricter __hash__ inheritance rules in 3.0. Several types
3216 which did not meet the rules for hash invariants and were already
3217 unhashable in 3.0 have now been explicitly flagged as unhashable in
3218 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3219 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3220
Brett Cannon88f801d2008-08-18 00:46:22 +00003221- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3222 imported into the module but exposed as part of the module's API.
3223
Brett Cannon7b96f072008-08-18 00:41:11 +00003224- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3225
Brett Cannon46225e72008-08-18 00:36:52 +00003226- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3227
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003228- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3229
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003230- Issue #3575: Incremental decoder's decode function now takes bytearray
3231 by using 's*' instead of 't#'.
3232
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003233- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003234 fails unicode conversion on 2nd parameter. (windows only)
3235
Facundo Batista94f243a2008-08-17 03:38:39 +00003236- Issue 2464. urllib2 now supports a malformation in the URL received
3237 in a redirect.
3238
Brett Cannonabe423e2008-08-16 21:47:07 +00003239- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003240 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003241
Facundo Batistaeb90b782008-08-16 14:44:07 +00003242- Issue #2776: fixed small issue when handling an URL with double slash
3243 after a 302 response in the case of not going through a proxy.
3244
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003245- Issue #2676: in the email package, content-type parsing was hanging on
3246 pathological input because of quadratic or exponential behaviour of a
3247 regular expression.
3248
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003249- Issue #3476: binary buffered reading through the new "io" library is now
3250 thread-safe.
3251
Brett Cannonbf3157b2008-08-14 05:00:03 +00003252- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3253 since mimetools itself is deprecated. Because modules are cached, all
3254 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3255
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003256- Issue #3134: shutil referenced undefined WindowsError symbol.
3257
Robert Schuppenies14646332008-08-10 11:01:53 +00003258- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3259 menu entries were not deleted.
3260
Brett Cannon83e81842008-08-09 23:30:55 +00003261- Copied the implementation of reduce() to _functools.reduce() to have a
3262 version that did not raise a DeprecationWarning under -3.
3263
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003264- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3265 a MemoryError rather than silently stop the iteration.
3266
Guido van Rossum59ce9012008-08-09 14:55:34 +00003267- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3268 to _sre.compile() will now be rejected. This should not affect anybody
3269 since the re.compile() function never generates invalid re-bytecode.
3270
Skip Montanaroa032bf42008-08-08 22:52:51 +00003271- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3272 upon first access it can be automatically initialized from the csv file if
3273 it wasn't initialized during instantiation.
3274
Brett Cannon3aa2a492008-08-06 22:28:09 +00003275- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3276 the reload() built-in has been removed.
3277
Brett Cannon7e30b672008-08-04 21:52:25 +00003278- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003279 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3282 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3283 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3284 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003285
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003286- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3287 raised an AttributeError.
3288
Benjamin Peterson01a24322008-07-28 23:35:27 +00003289- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003290 asking for a specific length. This problem only affected files opened
3291 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003292
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003293- Issue #3449: Update decimal module to use most recent specification
3294 (v. 1.68) and tests (v. 2.58) from IBM.
3295
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003296- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3297

3304
3305- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3306 invalid arguments.
3307
3308- Issue #3302: Fix several crashes when calling locale's gettext functions
3309 with None arguments.
3310
3311- Issue #3389: Allow resolving dotted names for handlers in logging
3312 configuration files.
3313
3314- Deprecate the sunaudio module for removal in Python 3.0.
3315
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003316- Issue #3394: zipfile.writestr sets external attributes when passed a
3317 file name rather than a ZipInfo instance, so files are extracted with
3318 mode 0600 rather than 000 under Unix.
3319
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003320- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3321 argument in python 2.5, this broke code that subclassed Popen to include its
3322 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3330-------------
3331
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003332- Issue #2235: the C API function PyObject_HashNotImplemented and its
3333 interaction with the tp_hash slot (added in 2.6b2) are now documented
3334
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003335- Issue #643841: The language reference now provides more detailed
3336 coverage of the lookup process for special methods. The disclaimers
3337 regarding lack of coverage of new-style classes have also been
3338 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003341What's New in Python 2.6 beta 2?
3342================================
3343
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003344*Release date: 17-Jul-2008*
3345
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003346Core and Builtins
3347-----------------
3348
Georg Brandl3e483f62008-07-16 22:57:41 +00003349- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3350 its methods now allow for items objects that can be converted to
3351 an integer using operator.index().
3352
Mark Dickinson64b7e502008-07-16 09:40:03 +00003353- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3354 produced a ValueError instead of giving the correct float.
3355
Eric Smitha5fa5a22008-07-16 00:11:49 +00003356- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3357 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3358
Mark Dickinson7103aa42008-07-15 19:08:33 +00003359- Issue #3008: the float type has a new instance method 'float.hex'
3360 and a new class method 'float.fromhex' to convert floating-point
3361 numbers to and from hexadecimal strings, respectively.
3362
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003363- Issue #2235: __hash__ is once again inherited by default. To allow
3364 collections.Hashable to remain meaningful in the presence of the
3365 default hash implementation (object.__hash__), it is now possible
3366 to explicit block inheritance of hash by setting __hash__=None at
3367 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3368 level.
3369
Nick Coghlanb028f502008-07-13 14:52:36 +00003370- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3371 the parent module cannot be found while performing an absolute import.
3372 This means that an incorrectly defined __package__ attribute will
3373 now only prevent relative imports in that module rather than causing
3374 all imports from that module to fail.
3375
Nick Coghlan14ff9942008-07-08 14:21:42 +00003376- Issue #2517: Allow unicode messages in Exceptions again by correctly
3377 bypassing the instance dictionary when looking up __unicode__ on
3378 new-style classes.
3379
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003380- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3381 set to a custom object whose write() method happens to install
3382 another file in sys.stdout.
3383
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003384- Issue #3088: Corrected a race condition in classes derived from

3386 another thread's dictionary.
3387
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003388- Issue #3004: Minor change to slice.indices(): the start and stop
3389 arguments are now treated identically, making the behaviour easier
3390 to describe and understand. For example, slice(None, -10,
3391 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3392 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3393 10, -1).
3394
Georg Brandl278fc502008-07-19 12:46:12 +00003395- Issue #3219: Calling a function with repeated keyword arguments,
3396 f(a=2, a=23), would not cause a syntax error. This was a regression
3397 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00003847 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003848
3849 This is controlled by the configure argument ``--with-universal-archs``:
3850

3852
3853 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3854
3855 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3856

Georg Brandl3ee81df2008-05-17 18:14:43 +00003909- Issue #1631171: Re-implement the 'warnings' module in C (the
3910 original Python code has been kept as backup). This will allow for
3911 using the 'warning's machinery in such places as the parser where
3912 use of pure Python code is not possible. Both the ``showarning()``
3913 and ``formatwarning()`` gain an optional 'line' argument which is
3914 not called by default for backwards-compatibility reasons. Setting
3915 ``warnings.showwarning()`` to an implementation that lacks support
3916 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003979- Issue #2550: The approach used by client/server code for obtaining
3980 ports to listen on in network-oriented tests has been refined in an
3981 effort to facilitate running multiple instances of the entire
3982 regression test suite in parallel without issue.
3983 test_support.bind_port() has been fixed such that it will always
3984 return a unique port -- which wasn't always the case with the
3985 previous implementation, especially if socket options had been set
3986 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3987 new implementation of bind_port() will actually raise an exception
3988 if it is passed an AF_INET/SOCK_STREAM socket with either the
3989 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3990 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3991 the socket it's been passed. This currently only applies to
3992 Windows. This option prevents any other sockets from binding to the
3993 host/port we've bound to, thus removing the possibility of the
3994 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3995 when a second SOCK_STREAM socket binds and accepts to a host/port
3996 that's already been bound by another socket. The optional preferred
3997 port parameter to bind_port() has been removed. Under no
3998 circumstances should tests be hard coding ports!
3999
4000 test_support.find_unused_port() has also been introduced, which will
4001 pass a temporary socket object to bind_port() in order to obtain an
4002 unused port. The temporary socket object is then closed and
4003 deleted, and the port is returned. This method should only be used
4004 for obtaining an unused port in order to pass to an external program
4005 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4006 a parameter to a server-oriented class that doesn't give you direct
4007 access to the underlying socket used.
4008
4009 Finally, test_support.HOST has been introduced, which should be used
4010 for the host argument of any relevant socket calls (i.e. bind and
4011 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004012
4013 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004014 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004015 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4016 test_asynchat and test_socket_ssl.
4017
Georg Brandl3ee81df2008-05-17 18:14:43 +00004018 It is now possible for multiple instances of the regression test
4019 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00004223- The bundled libffi copy is now in sync with the recently released
4224 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
4226 files are used. On all linux systems the --with-system-ffi
4227 configure option defaults to "yes".

4287
Fred Drakea8ee94b2008-03-01 02:45:07 +00004288- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004289 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00004291- Issue #2067: file.__exit__() now calls subclasses' close() method.
4292
4293- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004294
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004295- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004296 issue 215555 for a discussion.
4297
Eric Smitha73fbe72008-02-23 03:09:44 +00004298- Added the future_builtins module, which contains hex() and oct().
4299 These are the PEP 3127 version of these functions, designed to be
4300 compatible with the hex() and oct() builtins from Python 3.0. They
4301 differ slightly in their output formats from the existing, unchanged
4302 Python 2.6 builtins. The expected usage of the future_builtins
4303 module is:
4304 from future_builtins import hex, oct
4305
Eric Smith7ef40bf2008-02-20 23:34:22 +00004306- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4307 exponents for exponents with absolute value < 100. Follows C99
4308 standard. This is a change on Windows, which would use 3 digits.
4309 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4310 so that any alterations it does to the resulting string will be
4311 available in stringlib/formatter.h (for float.__format__).
4312
Eric Smith5a3c1352008-02-19 13:21:56 +00004313- Implemented PEP 3101, Advanced String Formatting. This adds a new
4314 builtin format(); a format() method for str and unicode; a
4315 __format__() method to object, str, unicode, int, long, float, and
4316 datetime; the class string.Formatter; and the C API
4317 PyObject_Format().
4318
Georg Brandl3ee81df2008-05-17 18:14:43 +00004319- Fixed several potential crashes, all caused by specially crafted
4320 __del__ methods exploiting objects in temporarily inconsistent
4321 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004322
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004323- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004324 prevent a possible crash: an Abstract Base Class would try to access
4325 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004326
Georg Brandl3ee81df2008-05-17 18:14:43 +00004327- Fixed repr() and str() of complex numbers with infinity or nan as
4328 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004329
Georg Brandl3ee81df2008-05-17 18:14:43 +00004330- Clear all free lists during a gc.collect() of the highest generation
4331 in order to allow pymalloc to free more arenas. Python may give back
4332 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004333
Georg Brandl3ee81df2008-05-17 18:14:43 +00004334- Issue #2045: Fix an infinite recursion triggered when printing a
4335 subclass of collections.defaultdict, if its default_factory is set
4336 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004337
Christian Heimesf75dbef2008-02-08 00:11:31 +00004338- Fixed a minor memory leak in dictobject.c. The content of the free
4339 list was not freed on interpreter shutdown.
4340
Georg Brandl21e99f42010-03-07 15:23:59 +00004341- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004342 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004343
Georg Brandl3ee81df2008-05-17 18:14:43 +00004344- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4345 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004346 to compact the internal free lists of pre-allocted ints and floats.
4347
Georg Brandl3ee81df2008-05-17 18:14:43 +00004348- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4349 calls. Python expected the return type int but the fork familie
4350 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004351
Georg Brandl3ee81df2008-05-17 18:14:43 +00004352- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4353 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004354
Georg Brandl3ee81df2008-05-17 18:14:43 +00004355- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4356 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004361- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4362 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004363
Georg Brandl3ee81df2008-05-17 18:14:43 +00004364- Patch #1473257: generator objects gain a gi_code attribute. This is
4365 the same object as the func_code attribute of the function that
4366 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004367
Georg Brandl3ee81df2008-05-17 18:14:43 +00004368- Issue #1920: "while 0" statements were completely removed by the
4369 compiler, even in the presence of an "else" clause, which is
4370 supposed to be run when the condition is false. Now the compiler
4371 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004372
Guido van Rossumeead05f2008-01-24 18:21:02 +00004373- A few crashers fixed: weakref_in_del.py (issue #1377858);
4374 loosing_dict_ref.py (issue #1303614, test67.py);
4375 borrowed_ref_[34].py (not in tracker).
4376
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004377- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004378 suppressed while an extension is loaded by calling SetErrorMode in
4379 dynload_win.c. The error is still reported properly.
4380
Georg Brandl3ee81df2008-05-17 18:14:43 +00004381- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004382 several extension methods and modules do not work without unicode
4383 support.
4384
Georg Brandl26543b12008-01-21 18:36:51 +00004385- Issue #1882: when compiling code from a string, encoding cookies in the
4386 second line of code were not always recognized correctly.
4387
Georg Brandl14404b62008-01-19 19:27:05 +00004388- Issue #1679: "0x" was taken as a valid integer literal.
4389
Georg Brandl6caad7d2008-01-26 14:19:22 +00004390- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004391 added.
4392
Christian Heimesc94e2b52008-01-14 04:13:37 +00004393- sys.float_info / PyFloat_GetInfo: The floating point information
4394 object was converted from a dict to a specialized structseq object.
4395
Georg Brandl3ee81df2008-05-17 18:14:43 +00004396- Patch #1816: Added sys.flags structseq. It exposes the status of
4397 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004398
Georg Brandl3ee81df2008-05-17 18:14:43 +00004399- Objects/structseq.c: Implemented new structseq representation. The
4400 patch makes structseqs (e.g. the return value of os.stat) more
4401 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004402
Georg Brandl3ee81df2008-05-17 18:14:43 +00004403- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00004425 and INF. float("nan"), float("inf") and float("-inf") now work on
4426 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004427
Georg Brandl3ee81df2008-05-17 18:14:43 +00004428- Compiler now generates simpler and faster code for dictionary
4429 literals. The oparg for BUILD_MAP now indicates an estimated
4430 dictionary size. There is a new opcode, STORE_MAP, for adding
4431 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004460- Patch #1739468: Directories and zipfiles containing a __main__.py
4461 file can now be directly executed by passing their name to the
4462 interpreter. The directory/zipfile is automatically inserted as the
4463 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004465- Issue #1265: Fix a problem with sys.settrace, if the tracing
4466 function uses a generator expression when at the same time the
4467 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004468
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004469- sets and frozensets now have an isdisjoint() method.

Neal Norwitz44f326e2007-10-05 05:29:17 +00004473- Fix warnings found by the new version of the Coverity checker.
4474
Georg Brandl21e99f42010-03-07 15:23:59 +00004475- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004476 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4477 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004478
Georg Brandl3ee81df2008-05-17 18:14:43 +00004479- Issue #1686386: Tuple's tp_repr did not take into account the
4480 possibility of having a self-referential tuple, which is possible
4481 from C code. Nor did object's tp_str consider that a type's tp_str
4482 could do something that could lead to an inifinite recursion.
4483 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4484 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004485
Georg Brandl3ee81df2008-05-17 18:14:43 +00004486- Issue #1164: It was possible to trigger deadlock when using the
4487 'print' statement to write to a file since the GIL was not released
4488 as needed. Now PyObject_Print() does the right thing along with
4489 various tp_print implementations of the built-in types and those in
4490 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004491
Georg Brandl3ee81df2008-05-17 18:14:43 +00004492- Issue #1147: Exceptions were directly allowing string exceptions in
4493 their throw() method even though string exceptions no longer
4494 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004495
Georg Brandl3ee81df2008-05-17 18:14:43 +00004496- Issue #1096: Prevent a segfault from getting the repr of a very
4497 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004498
Brett Cannon1e534b52007-09-07 04:18:30 +00004499- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004500 PyObject_Call() never calling back out to Python code to trigger
4501 recursion depth updates/checks. Required the creation of a static
4502 RuntimeError instance in case normalizing an exception put the
4503 recursion check value past its limit. Fixes crashers
4504 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004505

Neal Norwitz0ac60192007-05-27 04:08:54 +00004519- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004520 __*__ attributes. (Some already existed, e.g., __doc__ and
4521 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004522
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004523- Add -3 option to the interpreter to warn about features that are
4524 deprecated and will be changed/removed in Python 3.0.
4525
Georg Brandl2134e752007-05-21 20:34:16 +00004526- Patch #1686487: you can now pass any mapping after '**' in function
4527 calls.
4528
Collin Winter62903052007-05-18 23:11:24 +00004529- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004530 "except E as target:". This is to provide forwards compatibility
4531 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004532
Brett Cannon229cee22007-05-05 01:34:02 +00004533- Deprecate BaseException.message as per PEP 352.
4534
Georg Brandl3ee81df2008-05-17 18:14:43 +00004535- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004536 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004537
Vinay Sajip8549ce32007-05-06 17:53:37 +00004538- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004539 setting a plain string, ie don't expand to single letter identifiers.
4540
Raymond Hettinger13936692007-04-11 18:40:58 +00004541- Request #1191699: Slices can now be pickled.
4542
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004543- Request #1193128: str.translate() now allows a None argument for
4544 translations that only remove characters without re-mapping the
4545 remaining characters.
4546
Georg Brandl5cb76c12007-03-21 09:00:39 +00004547- Patch #1682205: a TypeError while unpacking an iterable is no longer
4548 masked by a generic one with the message "unpack non-sequence".
4549
Neal Norwitzaa754b72007-03-21 06:39:48 +00004550- Remove unused file Python/fmod.c.
4551
Guido van Rossum143b5642007-03-23 04:58:42 +00004552- Bug #1683368: The object.__init__() and object.__new__() methods are
4553 now stricter in rejecting excess arguments. The only time when
4554 either allows excess arguments is when it is not overridden and the
4555 other one is. For backwards compatibility, when both are
4556 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004557 warning later). Also, type.__init__() insists on the same signature
4558 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004559
Georg Brandl3ee81df2008-05-17 18:14:43 +00004560- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4561 object to complex using its __complex__() method before falling back
4562 to the __float__() method. Therefore, the functions in the cmath
4563 module now can operate on objects that define a __complex__()
4564 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004565
Georg Brandl3ee81df2008-05-17 18:14:43 +00004566- Patch #1623563: allow __class__ assignment for classes with
4567 __slots__. The old and the new class are still required to have the
4568 same slot names.

4574 ``object.__reduce_ex__()`` is called with an object that is faking
4575 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004576
Georg Brandl3ee81df2008-05-17 18:14:43 +00004577- Patch #1680015: Don't modify __slots__ tuple if it contains an

4581
Georg Brandl7b9c5552007-03-12 14:30:05 +00004582- Bug #1678647: write a newline after printing an exception in any
4583 case, even when converting the value to a string failed.
4584
Georg Brandl871f1bc2007-03-12 13:17:36 +00004585- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004586 its argument, if it exists. If not, it will work like before. This
4587 allows customizing the output of dir() in the presence of a
4588 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004596- Patch #1491866: change the complex() constructor to allow
4597 parthensized forms. This means complex(repr(x)) now works instead of
4598 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004599
Georg Brandlaa2321b2007-03-07 00:40:28 +00004600- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004601 makes the filenames the warning module prints much more sensible
4602 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004603

Georg Brandl0fca97a2007-03-05 22:28:08 +00004615- Patch #1674228: when assigning a slice (old-style), check for the
4616 sq_ass_slice instead of the sq_slice slot.
4617
Georg Brandl3ee81df2008-05-17 18:14:43 +00004618- When printing an unraisable error, don't print exceptions. before
4619 the name. This duplicates the behavior whening normally printing
4620 exceptions.

5248 -- the failure just occurred later, with a more cumbersome
5249 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005530- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5531 with RFC 3207 and forgets any knowledge obtained from the server not
5532 obtained from the TLS negotiation itself. Patch contributed by Bill
5533 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005534
Georg Brandl3ee81df2008-05-17 18:14:43 +00005535- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005536 that the SMTP.starttls() caller no longer needs to call ehlo()
5537 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005538 does not claim to support starttls. Adds the
5539 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5620 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5621 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00005623

Georg Brandl3ee81df2008-05-17 18:14:43 +00005638 time so that opening a database previously created with the DB_DUP
5639 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5640 opens. Specifically: dictionary assignment to a DB object will
5641 replace all values for a given key when the database allows
5642 duplicate values. DB users should use DB.put(k, v) when they want
5643 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005644

5650 characters with ASCII value less than 32. Also, it correctly quotes
5651 dots only if they occur on a single line, as opposed to the previous
5652 behavior of quoting dots if they are the second character of any
5653 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005654

5981 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005982
Georg Brandl3ee81df2008-05-17 18:14:43 +00005983- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5984 to ``PyTuple_SetItem``, it can be used to populate a brand new

5997
Georg Brandl3ee81df2008-05-17 18:14:43 +00005998- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5999 of w# format code incorrectly truncated the length to an int, even
6000 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6001 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006002
Georg Brandl3ee81df2008-05-17 18:14:43 +00006003- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6021- Fix some leftovers from the conversion from int to Py_ssize_t
6022 (relevant to strings and sequences of more than 2**31 items).
6023
6024- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6025 outside of pystate.c and should not be necessary.
6026
Georg Brandl3ee81df2008-05-17 18:14:43 +00006027- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6028 absolute imports. In earlier versions they might have used relative
6029 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006030
Georg Brandl3ee81df2008-05-17 18:14:43 +00006031- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6032 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006033
Georg Brandl3ee81df2008-05-17 18:14:43 +00006034- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006059- Removed the macfs module. It had been deprecated since Python 2.5.
6060 This lead to the deprecation of macostools.touched() as it relied
6061 solely on macfs and was a no-op under OS X.
