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.

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,

146 non-float non-integer argument is now converted to an integer (if possible)
147 using its __int__ method. Previously, only small arguments were treated this

Georg Brandlfee0f442010-05-22 21:26:21 +0000157 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +0000158 benefit compared to the dynamic memory allocation fallback. Patch by

Georg Brandlfee0f442010-05-22 21:26:21 +0000266- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
267 string "python" as the *ident*. openlog() arguments are all optional and
268 keywords.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000348 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

371-----------------
372
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000373- Issue #7301: Add environment variable $PYTHONWARNINGS.
374
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000375- Issue #8329: Don't return the same lists from select.select when no fds are
376 changed.
377
Georg Brandlfee0f442010-05-22 21:26:21 +0000378- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000379 on 64-bit machines. The shift count for either left or right shift is
380 permitted to be up to sys.maxsize.
381
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000382- Ensure that tokenization of identifiers is not affected by locale.

387
Georg Brandlfee0f442010-05-22 21:26:21 +0000388- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
389 with a non-empty format string. This is an effort to future-proof user
390 code. If a derived class does not currently implement __format__ but later
391 adds its own __format__, it would most likely break user code that had
392 supplied a format string. This will be changed to a DeprecationWaring in
393 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000394
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000395- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000420- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000421 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

425
Georg Brandlfee0f442010-05-22 21:26:21 +0000426- Issue #8257: The Decimal construct now accepts a float instance directly,
427 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000428
429 >>> Decimal(1.1)

431
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000432- collections.Counter() now supports a subtract() method.
433
Georg Brandlfee0f442010-05-22 21:26:21 +0000434- The functools module now has a total_ordering() class decorator to simplify
435 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000436
Georg Brandlfee0f442010-05-22 21:26:21 +0000437- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +0000443- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
444 InvalidOperation instead of returning False. (Comparisons involving a quiet
445 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
446 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000447
Georg Brandlfee0f442010-05-22 21:26:21 +0000448- Issue #2531: Comparison operations between floats and Decimal instances now
449 return a result based on the numeric values of the operands; previously they
450 returned an arbitrary result based on the relative ordering of id(float) and
451 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000452
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000453- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000454 argument `-` which tells it to read files to compile from stdin. Each line is
455 read on demand and the named file is compiled immediately. (Original patch by
456 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000465- Comparisons using one of <, <=, >, >= between a complex instance and a
466 Fractions instance now raise TypeError instead of returning True/False. This
467 makes Fraction <=> complex comparisons consistent with int <=> complex, float
468 <=> complex, and complex <=> complex comparisons.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000875- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000876 file position when calling `truncate()`. It would previously change the file
877 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000878 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

881
Georg Brandlba83f822010-03-14 09:50:54 +0000882- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
883 class used to represent files stored inside an archive. The new
884 implementation is significantly faster and can be wrapped in a
885 ``io.BufferedReader`` object for more speedups. It also solves an issue
886 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
887 Patch by Nir Aides.

895 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000896
Georg Brandlba83f822010-03-14 09:50:54 +0000897- Issue #7748: Since unicode values are supported for some metadata options in
898 Distutils, the DistributionMetadata get_* methods will now return an utf-8
899 encoded string for them. This ensures that the upload and register commands
900 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001171- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1172 decimal string that's guaranteed to round back to x under correct rounding
1173 (with round-half-to-even rounding mode). Previously it gave a string based on
1174 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1175 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1176 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001177
Georg Brandlba83f822010-03-14 09:50:54 +00001178- Issue #7117: On almost all platforms: float-to-string and string-to-float
1179 conversions within Python are now correctly rounded. Places these conversions
1180 occur include: str for floats and complex numbers; the float and complex
1181 constructors; old-style and new-style numeric formatting; serialization and
1182 deserialization of floats and complex numbers using marshal, pickle and json;
1183 parsing of float and imaginary literals in Python code; Decimal-to-float
1184 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001185
Georg Brandlba83f822010-03-14 09:50:54 +00001186 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1187 providing correctly-rounded strtod and dtoa C functions. This code is
1188 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1189 the C compiler. There may be a small number of platforms on which correct
1190 operation of this code cannot be guaranteed, so the code is not used: notably,
1191 this applies to platforms where the C double format is not IEEE 754 binary64,
1192 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1193 and Python's configure script is unable to determine how to change the FPU
1194 precision. On these platforms conversions use the platform strtod and dtoa,
1195 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001197- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1198 uses the correctly-rounded string <-> float conversions described above (when
1199 available), and so produces correctly rounded results that will display nicely
1200 under the float repr. There are two related small changes: (1) round now
1201 accepts any class with an ``__index__()`` method for its second argument (but
1202 no longer accepts floats for the second argument), and (2) an excessively
1203 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1204 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001351- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1352 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1353 but with at least one decimal point and with a default precision
1354 of 12. Previously, the behavior the same but with a default precision of 6.
1355 This more closely matches ``str()``, and reduces surprises when adding
1356 alignment flags to the empty presentation type. This also affects the new
1357 complex.__format__ in the same way.
1358

Georg Brandlba83f822010-03-14 09:50:54 +00001497- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1498 existing .py counterpart, override the co_filename attributes of all code
1499 objects if the original filename is obsolete (which can happen if the file has

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001545- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

1547 instead of throwing a MemoryError.
1548
Georg Brandlba83f822010-03-14 09:50:54 +00001549- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1554
Georg Brandlba83f822010-03-14 09:50:54 +00001555- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1556 file objects with closefd=False. The file descriptor is still kept open but
1557 the file object behaves like a closed file. The ``FileIO`` object also got a
1558 new readonly attribute ``closefd``.

1577
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001578- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001579 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00001581- On windows, ``os.chdir()`` given unicode was not working if
1582 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1583 this code path is really executed because I cannot move to such directory on
1584 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001585
Georg Brandlba83f822010-03-14 09:50:54 +00001586- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1587 element is temporarily replaced with an equivalent frozenset. But the
1588 eventual KeyError would always report the empty ``frozenset()`` as the missing
1589 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001609- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1610 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1611 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1612 of using the replace error handler in PyUnicode_DecodeUTF8().
1613
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001614- Issue #3739: The unicode-internal encoder now reports the number of characters

1616
Georg Brandlba83f822010-03-14 09:50:54 +00001617- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1618 allocator will be automatically disabled when running under Valgrind. This
1619 gives improved memory leak detection when running under Valgrind, while taking
1620 advantage of pymalloc at other times.

1691 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00001692 __main__.py file. This allows applications that run other Python scripts to
1693 support the same flexibility as the CPython command line itself.

1697 timeout is 20 seconds, which should be amply sufficient for local connections.

Georg Brandlba83f822010-03-14 09:50:54 +00002427 for *nix machines for negative handles and large int handles. Without this
2428 check it is possible to segfault the interpreter.

Georg Brandlba83f822010-03-14 09:50:54 +00002447 the timestamp in the gzip stream. The default value remains the current time.

2844 threads could return successfully while some Thread objects were still
2845 referenced. This also introduces a new private function: ``thread._count()``.

2986
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002987- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2988 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2989 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2990 ``printf`` function, whereas PyString_FromFormat has an independent
2991 implementation and uses "%zd" on all platforms for size_t values.
2992 This makes a difference on win64, where ``printf`` needs "%Id" to display
2993 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002995- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2999 object; previously an int would be returned for small values. the __long__
3000 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003010 was correctly parsed but parsing of subsequent arguments failed.
3011
Vinay Sajip35e3b032008-09-01 14:33:59 +00003012- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003013 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3014 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3015 when given a tuple of classes as second argument, were looking up
3016 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3017 type object.

3111
Jesse Noller438195f2009-01-18 21:04:36 +00003112- Issue #4301: Patch the logging module to add processName support, remove
3113 _check_logger_class from multiprocessing.
3114
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003115- Issue #2975: When compiling several extension modules with Visual Studio 2008
3116 from the same python interpreter, some environment variables would grow
3117 without limit.
3118
Benjamin Peterson37346b22008-08-23 20:27:43 +00003119- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3120 exploitation of poor argument checking.
3121

3125 remaining ones have "pysqlite_" prefix.
3126
Gerhard Häringe6872eb2008-09-12 22:33:22 +00003127- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

3135 wrapper for warnings.catch_warnings() that makes it easier to check
3136 that expected warning messages are being reported.
3137
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003138- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003156What's New in Python 2.6 beta 3?
3157================================
3158
Barry Warsaw07a4a382008-08-21 01:15:08 +00003159*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003160
3161Core and Builtins
3162-----------------
3163
Guido van Rossumf8402962008-08-20 15:01:50 +00003164- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3165 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3166 extensions do not automatically benefit from the class attribute
3167 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3168 to their tp_flags field if they care. This is a backwards
3169 compatibility feature; in 3.0, all types will use the cache by
3170 default.
3171
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003172- Keyword arguments can now follow starred arguments. (``f(a, *args,
3173 keyword=23)`` is now valid syntax.)
3174
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003175- ctypes function pointers that are COM methods have a boolean True
3176 value again.
3177
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003178- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3179 by denying s# to parse objects that have a releasebuffer procedure,
3180 and introducing s*.
3181
Georg Brandl1e13ea92008-08-11 09:07:59 +00003182- Issue #3537: Fix an assertion failure when an empty but presized dict
3183 object was stored in the freelist.
3184
Mark Dickinsonb6467572008-08-04 21:30:09 +00003185- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3186 ValueError consistently across platforms.
3187
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003188- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3189 (64bit Unix, for example), unichr() would truncate its argument and return
3190 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3191
Neal Norwitze7d8be82008-07-31 17:17:14 +00003192- Apply security patches from Apple.
3193
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003194- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3195 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3196
Antoine Pitrou92f82162008-07-25 22:22:08 +00003197- Issue #1819: function calls with several named parameters are now on
3198 average 35% faster (as measured by pybench).
3199
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003200- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3201 the python debugger steps into a class statement: the free variables (local
3202 variables defined in an outer scope) would be deleted from the outer scope.
3203
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003204- Issue #2620: Overflow checking when allocating or reallocating memory
3205 was not always being done properly in some python types and extension
3206 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3207 all been updated to perform better checks and places in the code that
3208 would previously leak memory on the error path when such an allocation
3209 failed have been fixed.
3210
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003211Library
3212-------
3213
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003214- Issue #3612: Added some missing basic types in ctypes.wintypes.
3215
Benjamin Petersone977ad42008-08-20 01:42:01 +00003216- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3217 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3218
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003219- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3220 version reported by these tools does not necessarily follow the python
3221 version numbering scheme, so the module is less strict when parsing it.
3222
Nick Coghlanf70385a2008-08-18 12:42:46 +00003223- Issue #2235: Added Py3k warnings for types which will become unhashable
3224 under the stricter __hash__ inheritance rules in 3.0. Several types
3225 which did not meet the rules for hash invariants and were already
3226 unhashable in 3.0 have now been explicitly flagged as unhashable in
3227 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3228 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3229
Brett Cannon88f801d2008-08-18 00:46:22 +00003230- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3231 imported into the module but exposed as part of the module's API.
3232
Brett Cannon7b96f072008-08-18 00:41:11 +00003233- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3234
Brett Cannon46225e72008-08-18 00:36:52 +00003235- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3236
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003237- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3238
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003239- Issue #3575: Incremental decoder's decode function now takes bytearray
3240 by using 's*' instead of 't#'.
3241
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003242- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003243 fails unicode conversion on 2nd parameter. (windows only)
3244
Facundo Batista94f243a2008-08-17 03:38:39 +00003245- Issue 2464. urllib2 now supports a malformation in the URL received
3246 in a redirect.
3247
Brett Cannonabe423e2008-08-16 21:47:07 +00003248- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003249 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003250
Facundo Batistaeb90b782008-08-16 14:44:07 +00003251- Issue #2776: fixed small issue when handling an URL with double slash
3252 after a 302 response in the case of not going through a proxy.
3253
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003254- Issue #2676: in the email package, content-type parsing was hanging on
3255 pathological input because of quadratic or exponential behaviour of a
3256 regular expression.
3257
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003258- Issue #3476: binary buffered reading through the new "io" library is now
3259 thread-safe.
3260
Brett Cannonbf3157b2008-08-14 05:00:03 +00003261- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3262 since mimetools itself is deprecated. Because modules are cached, all
3263 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3264
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003265- Issue #3134: shutil referenced undefined WindowsError symbol.
3266
Robert Schuppenies14646332008-08-10 11:01:53 +00003267- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3268 menu entries were not deleted.
3269
Brett Cannon83e81842008-08-09 23:30:55 +00003270- Copied the implementation of reduce() to _functools.reduce() to have a
3271 version that did not raise a DeprecationWarning under -3.
3272
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003273- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3274 a MemoryError rather than silently stop the iteration.
3275
Guido van Rossum59ce9012008-08-09 14:55:34 +00003276- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3277 to _sre.compile() will now be rejected. This should not affect anybody
3278 since the re.compile() function never generates invalid re-bytecode.
3279
Skip Montanaroa032bf42008-08-08 22:52:51 +00003280- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3281 upon first access it can be automatically initialized from the csv file if
3282 it wasn't initialized during instantiation.
3283
Brett Cannon3aa2a492008-08-06 22:28:09 +00003284- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3285 the reload() built-in has been removed.
3286
Brett Cannon7e30b672008-08-04 21:52:25 +00003287- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003288 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003289 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3290 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3291 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3292 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3293 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003294
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003295- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3296 raised an AttributeError.
3297
Benjamin Peterson01a24322008-07-28 23:35:27 +00003298- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003299 asking for a specific length. This problem only affected files opened
3300 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003301
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003302- Issue #3449: Update decimal module to use most recent specification
3303 (v. 1.68) and tests (v. 2.58) from IBM.
3304
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003305- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3306
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003307- Issue 1592: Improve error reporting when operations are attempted
3308 on a closed shelf.

3311
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003312- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3313
3314- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3315 invalid arguments.
3316
3317- Issue #3302: Fix several crashes when calling locale's gettext functions
3318 with None arguments.
3319
3320- Issue #3389: Allow resolving dotted names for handlers in logging
3321 configuration files.
3322
3323- Deprecate the sunaudio module for removal in Python 3.0.
3324
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003325- Issue #3394: zipfile.writestr sets external attributes when passed a
3326 file name rather than a ZipInfo instance, so files are extracted with
3327 mode 0600 rather than 000 under Unix.
3328
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003329- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3330 argument in python 2.5, this broke code that subclassed Popen to include its
3331 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3339-------------
3340
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003341- Issue #2235: the C API function PyObject_HashNotImplemented and its
3342 interaction with the tp_hash slot (added in 2.6b2) are now documented
3343
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003344- Issue #643841: The language reference now provides more detailed
3345 coverage of the lookup process for special methods. The disclaimers
3346 regarding lack of coverage of new-style classes have also been
3347 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003350What's New in Python 2.6 beta 2?
3351================================
3352
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003353*Release date: 17-Jul-2008*
3354
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003355Core and Builtins
3356-----------------
3357
Georg Brandl3e483f62008-07-16 22:57:41 +00003358- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3359 its methods now allow for items objects that can be converted to
3360 an integer using operator.index().
3361
Mark Dickinson64b7e502008-07-16 09:40:03 +00003362- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3363 produced a ValueError instead of giving the correct float.
3364
Eric Smitha5fa5a22008-07-16 00:11:49 +00003365- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3366 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3367
Mark Dickinson7103aa42008-07-15 19:08:33 +00003368- Issue #3008: the float type has a new instance method 'float.hex'
3369 and a new class method 'float.fromhex' to convert floating-point
3370 numbers to and from hexadecimal strings, respectively.
3371
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003372- Issue #2235: __hash__ is once again inherited by default. To allow
3373 collections.Hashable to remain meaningful in the presence of the
3374 default hash implementation (object.__hash__), it is now possible
3375 to explicit block inheritance of hash by setting __hash__=None at
3376 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3377 level.
3378
Nick Coghlanb028f502008-07-13 14:52:36 +00003379- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3380 the parent module cannot be found while performing an absolute import.
3381 This means that an incorrectly defined __package__ attribute will
3382 now only prevent relative imports in that module rather than causing
3383 all imports from that module to fail.
3384
Nick Coghlan14ff9942008-07-08 14:21:42 +00003385- Issue #2517: Allow unicode messages in Exceptions again by correctly
3386 bypassing the instance dictionary when looking up __unicode__ on
3387 new-style classes.
3388
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003389- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3390 set to a custom object whose write() method happens to install
3391 another file in sys.stdout.
3392
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003393- Issue #3088: Corrected a race condition in classes derived from
3394 threading.local: the first member set by a thread could be saved in
3395 another thread's dictionary.
3396
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003397- Issue #3004: Minor change to slice.indices(): the start and stop
3398 arguments are now treated identically, making the behaviour easier
3399 to describe and understand. For example, slice(None, -10,
3400 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3401 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

3855 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003856 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003857
3858 This is controlled by the configure argument ``--with-universal-archs``:
3859
3860 - ``--with-universal-archs=all``: install 4-way universal
3861
3862 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3863
3864 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3865
3866 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003918- Issue #1631171: Re-implement the 'warnings' module in C (the
3919 original Python code has been kept as backup). This will allow for
3920 using the 'warning's machinery in such places as the parser where
3921 use of pure Python code is not possible. Both the ``showarning()``
3922 and ``formatwarning()`` gain an optional 'line' argument which is
3923 not called by default for backwards-compatibility reasons. Setting
3924 ``warnings.showwarning()`` to an implementation that lacks support
3925 for the ``line`` argument will raise a DeprecationWarning.

3949
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003950- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00003988- Issue #2550: The approach used by client/server code for obtaining
3989 ports to listen on in network-oriented tests has been refined in an
3990 effort to facilitate running multiple instances of the entire
3991 regression test suite in parallel without issue.
3992 test_support.bind_port() has been fixed such that it will always
3993 return a unique port -- which wasn't always the case with the
3994 previous implementation, especially if socket options had been set
3995 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3996 new implementation of bind_port() will actually raise an exception
3997 if it is passed an AF_INET/SOCK_STREAM socket with either the
3998 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3999 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4000 the socket it's been passed. This currently only applies to
4001 Windows. This option prevents any other sockets from binding to the
4002 host/port we've bound to, thus removing the possibility of the
4003 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4004 when a second SOCK_STREAM socket binds and accepts to a host/port
4005 that's already been bound by another socket. The optional preferred
4006 port parameter to bind_port() has been removed. Under no
4007 circumstances should tests be hard coding ports!
4008
4009 test_support.find_unused_port() has also been introduced, which will
4010 pass a temporary socket object to bind_port() in order to obtain an
4011 unused port. The temporary socket object is then closed and
4012 deleted, and the port is returned. This method should only be used
4013 for obtaining an unused port in order to pass to an external program
4014 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4015 a parameter to a server-oriented class that doesn't give you direct
4016 access to the underlying socket used.
4017
4018 Finally, test_support.HOST has been introduced, which should be used
4019 for the host argument of any relevant socket calls (i.e. bind and
4020 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004021
4022 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004023 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004024 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4025 test_asynchat and test_socket_ssl.
4026
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027 It is now possible for multiple instances of the regression test
4028 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00004232- The bundled libffi copy is now in sync with the recently released
4233 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004234 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
4235 files are used. On all linux systems the --with-system-ffi
4236 configure option defaults to "yes".

4296
Fred Drakea8ee94b2008-03-01 02:45:07 +00004297- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004298 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004299
Georg Brandlad61bc82008-02-23 15:11:18 +00004300- Issue #2067: file.__exit__() now calls subclasses' close() method.
4301
4302- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004303
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004304- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004305 issue 215555 for a discussion.
4306
Eric Smitha73fbe72008-02-23 03:09:44 +00004307- Added the future_builtins module, which contains hex() and oct().
4308 These are the PEP 3127 version of these functions, designed to be
4309 compatible with the hex() and oct() builtins from Python 3.0. They
4310 differ slightly in their output formats from the existing, unchanged
4311 Python 2.6 builtins. The expected usage of the future_builtins
4312 module is:
4313 from future_builtins import hex, oct
4314
Eric Smith7ef40bf2008-02-20 23:34:22 +00004315- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4316 exponents for exponents with absolute value < 100. Follows C99
4317 standard. This is a change on Windows, which would use 3 digits.
4318 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4319 so that any alterations it does to the resulting string will be
4320 available in stringlib/formatter.h (for float.__format__).
4321
Eric Smith5a3c1352008-02-19 13:21:56 +00004322- Implemented PEP 3101, Advanced String Formatting. This adds a new
4323 builtin format(); a format() method for str and unicode; a
4324 __format__() method to object, str, unicode, int, long, float, and
4325 datetime; the class string.Formatter; and the C API
4326 PyObject_Format().
4327
Georg Brandl3ee81df2008-05-17 18:14:43 +00004328- Fixed several potential crashes, all caused by specially crafted
4329 __del__ methods exploiting objects in temporarily inconsistent
4330 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004331
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004332- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004333 prevent a possible crash: an Abstract Base Class would try to access
4334 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004335
Georg Brandl3ee81df2008-05-17 18:14:43 +00004336- Fixed repr() and str() of complex numbers with infinity or nan as
4337 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004338
Georg Brandl3ee81df2008-05-17 18:14:43 +00004339- Clear all free lists during a gc.collect() of the highest generation
4340 in order to allow pymalloc to free more arenas. Python may give back
4341 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004342
Georg Brandl3ee81df2008-05-17 18:14:43 +00004343- Issue #2045: Fix an infinite recursion triggered when printing a
4344 subclass of collections.defaultdict, if its default_factory is set
4345 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004346
Christian Heimesf75dbef2008-02-08 00:11:31 +00004347- Fixed a minor memory leak in dictobject.c. The content of the free
4348 list was not freed on interpreter shutdown.
4349
Georg Brandl21e99f42010-03-07 15:23:59 +00004350- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004351 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004352
Georg Brandl3ee81df2008-05-17 18:14:43 +00004353- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4354 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004355 to compact the internal free lists of pre-allocted ints and floats.
4356
Georg Brandl3ee81df2008-05-17 18:14:43 +00004357- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4358 calls. Python expected the return type int but the fork familie
4359 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004360
Georg Brandl3ee81df2008-05-17 18:14:43 +00004361- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4362 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004363
Georg Brandl3ee81df2008-05-17 18:14:43 +00004364- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4365 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004366
Georg Brandl3ee81df2008-05-17 18:14:43 +00004367- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4368 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004370- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4371 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004372
Georg Brandl3ee81df2008-05-17 18:14:43 +00004373- Patch #1473257: generator objects gain a gi_code attribute. This is
4374 the same object as the func_code attribute of the function that
4375 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004376
Georg Brandl3ee81df2008-05-17 18:14:43 +00004377- Issue #1920: "while 0" statements were completely removed by the
4378 compiler, even in the presence of an "else" clause, which is
4379 supposed to be run when the condition is false. Now the compiler
4380 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004381
Guido van Rossumeead05f2008-01-24 18:21:02 +00004382- A few crashers fixed: weakref_in_del.py (issue #1377858);
4383 loosing_dict_ref.py (issue #1303614, test67.py);
4384 borrowed_ref_[34].py (not in tracker).
4385
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004386- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004387 suppressed while an extension is loaded by calling SetErrorMode in
4388 dynload_win.c. The error is still reported properly.
4389
Georg Brandl3ee81df2008-05-17 18:14:43 +00004390- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004391 several extension methods and modules do not work without unicode
4392 support.
4393
Georg Brandl26543b12008-01-21 18:36:51 +00004394- Issue #1882: when compiling code from a string, encoding cookies in the
4395 second line of code were not always recognized correctly.
4396
Georg Brandl14404b62008-01-19 19:27:05 +00004397- Issue #1679: "0x" was taken as a valid integer literal.
4398
Georg Brandl6caad7d2008-01-26 14:19:22 +00004399- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004400 added.
4401
Christian Heimesc94e2b52008-01-14 04:13:37 +00004402- sys.float_info / PyFloat_GetInfo: The floating point information
4403 object was converted from a dict to a specialized structseq object.
4404
Georg Brandl3ee81df2008-05-17 18:14:43 +00004405- Patch #1816: Added sys.flags structseq. It exposes the status of
4406 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004407
Georg Brandl3ee81df2008-05-17 18:14:43 +00004408- Objects/structseq.c: Implemented new structseq representation. The
4409 patch makes structseqs (e.g. the return value of os.stat) more
4410 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004411
Georg Brandl3ee81df2008-05-17 18:14:43 +00004412- Patch #1700288: added a type attribute cache that caches method
4413 accesses, resulting in speedups in heavily object-oriented code.

4421 envvar and sys.dont_write_bytecode attribute. All these can be set
4422 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004423
Georg Brandl3ee81df2008-05-17 18:14:43 +00004424- Improve some exception messages when Windows fails to load an
4425 extension module. Now we get for example '%1 is not a valid Win32
4426 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004427

Christian Heimes0a8143f2007-12-18 23:22:54 +00004433- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004434 and INF. float("nan"), float("inf") and float("-inf") now work on
4435 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004436
Georg Brandl3ee81df2008-05-17 18:14:43 +00004437- Compiler now generates simpler and faster code for dictionary
4438 literals. The oparg for BUILD_MAP now indicates an estimated
4439 dictionary size. There is a new opcode, STORE_MAP, for adding
4440 entries to the dictionary.

4465
Georg Brandl3ee81df2008-05-17 18:14:43 +00004466- Issue #1460: The utf-7 incremental decoder did not accept truncated
4467 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00004468
Georg Brandl3ee81df2008-05-17 18:14:43 +00004469- Patch #1739468: Directories and zipfiles containing a __main__.py
4470 file can now be directly executed by passing their name to the
4471 interpreter. The directory/zipfile is automatically inserted as the
4472 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004473
Georg Brandl3ee81df2008-05-17 18:14:43 +00004474- Issue #1265: Fix a problem with sys.settrace, if the tracing
4475 function uses a generator expression when at the same time the
4476 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004477
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004478- sets and frozensets now have an isdisjoint() method.

4481
Neal Norwitz44f326e2007-10-05 05:29:17 +00004482- Fix warnings found by the new version of the Coverity checker.
4483
Georg Brandl21e99f42010-03-07 15:23:59 +00004484- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4486 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004487
Georg Brandl3ee81df2008-05-17 18:14:43 +00004488- Issue #1686386: Tuple's tp_repr did not take into account the
4489 possibility of having a self-referential tuple, which is possible
4490 from C code. Nor did object's tp_str consider that a type's tp_str
4491 could do something that could lead to an inifinite recursion.
4492 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4493 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004494
Georg Brandl3ee81df2008-05-17 18:14:43 +00004495- Issue #1164: It was possible to trigger deadlock when using the
4496 'print' statement to write to a file since the GIL was not released
4497 as needed. Now PyObject_Print() does the right thing along with
4498 various tp_print implementations of the built-in types and those in
4499 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004500
Georg Brandl3ee81df2008-05-17 18:14:43 +00004501- Issue #1147: Exceptions were directly allowing string exceptions in
4502 their throw() method even though string exceptions no longer
4503 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004504
Georg Brandl3ee81df2008-05-17 18:14:43 +00004505- Issue #1096: Prevent a segfault from getting the repr of a very
4506 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004507
Brett Cannon1e534b52007-09-07 04:18:30 +00004508- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004509 PyObject_Call() never calling back out to Python code to trigger
4510 recursion depth updates/checks. Required the creation of a static
4511 RuntimeError instance in case normalizing an exception put the
4512 recursion check value past its limit. Fixes crashers
4513 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004514
Georg Brandl3ee81df2008-05-17 18:14:43 +00004515- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004528- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004529 __*__ attributes. (Some already existed, e.g., __doc__ and
4530 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004531
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004532- Add -3 option to the interpreter to warn about features that are
4533 deprecated and will be changed/removed in Python 3.0.
4534
Georg Brandl2134e752007-05-21 20:34:16 +00004535- Patch #1686487: you can now pass any mapping after '**' in function
4536 calls.
4537
Collin Winter62903052007-05-18 23:11:24 +00004538- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004539 "except E as target:". This is to provide forwards compatibility
4540 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004541
Brett Cannon229cee22007-05-05 01:34:02 +00004542- Deprecate BaseException.message as per PEP 352.
4543
Georg Brandl3ee81df2008-05-17 18:14:43 +00004544- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004545 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004546
Vinay Sajip8549ce32007-05-06 17:53:37 +00004547- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004548 setting a plain string, ie don't expand to single letter identifiers.
4549
Raymond Hettinger13936692007-04-11 18:40:58 +00004550- Request #1191699: Slices can now be pickled.
4551
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004552- Request #1193128: str.translate() now allows a None argument for
4553 translations that only remove characters without re-mapping the
4554 remaining characters.
4555
Georg Brandl5cb76c12007-03-21 09:00:39 +00004556- Patch #1682205: a TypeError while unpacking an iterable is no longer
4557 masked by a generic one with the message "unpack non-sequence".
4558
Neal Norwitzaa754b72007-03-21 06:39:48 +00004559- Remove unused file Python/fmod.c.
4560
Guido van Rossum143b5642007-03-23 04:58:42 +00004561- Bug #1683368: The object.__init__() and object.__new__() methods are
4562 now stricter in rejecting excess arguments. The only time when
4563 either allows excess arguments is when it is not overridden and the
4564 other one is. For backwards compatibility, when both are
4565 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004566 warning later). Also, type.__init__() insists on the same signature
4567 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004568
Georg Brandl3ee81df2008-05-17 18:14:43 +00004569- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4570 object to complex using its __complex__() method before falling back
4571 to the __float__() method. Therefore, the functions in the cmath
4572 module now can operate on objects that define a __complex__()
4573 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004574
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Patch #1623563: allow __class__ assignment for classes with
4576 __slots__. The old and the new class are still required to have the
4577 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00004578
Georg Brandl3ee81df2008-05-17 18:14:43 +00004579- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00004582- Patch #1462488: Python no longer segfaults when
4583 ``object.__reduce_ex__()`` is called with an object that is faking
4584 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004585
Georg Brandl3ee81df2008-05-17 18:14:43 +00004586- Patch #1680015: Don't modify __slots__ tuple if it contains an

4590
Georg Brandl7b9c5552007-03-12 14:30:05 +00004591- Bug #1678647: write a newline after printing an exception in any
4592 case, even when converting the value to a string failed.
4593
Georg Brandl871f1bc2007-03-12 13:17:36 +00004594- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004595 its argument, if it exists. If not, it will work like before. This
4596 allows customizing the output of dir() in the presence of a
4597 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004598
Collin Winter276887b2007-03-12 16:11:39 +00004599- Patch #922167: Python no longer segfaults when faced with infinitely
4600 self-recursive reload() calls (as reported by bug #742342).
4601
Georg Brandl3ee81df2008-05-17 18:14:43 +00004602- Patch #1675981: remove unreachable code from ``type.__new__()``
4603 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004605- Patch #1491866: change the complex() constructor to allow
4606 parthensized forms. This means complex(repr(x)) now works instead of
4607 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004608
Georg Brandlaa2321b2007-03-07 00:40:28 +00004609- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004610 makes the filenames the warning module prints much more sensible
4611 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004612
Georg Brandl49aafc92007-03-07 00:34:46 +00004613- Variant of patch #697613: don't exit the interpreter on a SystemExit
4614 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004615 variable is given, but break into the interactive interpreter just
4616 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004621- Bug #1674503: close the file opened by execfile() in an error
4622 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00004623
Georg Brandl0fca97a2007-03-05 22:28:08 +00004624- Patch #1674228: when assigning a slice (old-style), check for the
4625 sq_ass_slice instead of the sq_slice slot.
4626
Georg Brandl3ee81df2008-05-17 18:14:43 +00004627- When printing an unraisable error, don't print exceptions. before
4628 the name. This duplicates the behavior whening normally printing
4629 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00004630
Georg Brandl3ee81df2008-05-17 18:14:43 +00004631- Bug #1653736: Properly discard third argument to

4638 created a weakref on itself during a __del__ call for new-style
4639 classes (classic classes still have the bug).

4686
Armin Rigo7ccbca92006-10-04 12:17:45 +00004687- A number of places, including integer negation and absolute value,
4688 were fixed to not rely on undefined behaviour of the C compiler
4689 anymore.

5195
Georg Brandl92a6bae2007-03-13 17:43:32 +00005196- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005197 are set for invalid interpolation sequences that would lead to

5254 TestCase and TestSuite subclasses (not instances) are no longer
5255 accepted in TestSuite.addTest(). This should cause no
5256 incompatibility since it never made sense with ordinary subclasses
5257 -- the failure just occurred later, with a more cumbersome
5258 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005539- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5540 with RFC 3207 and forgets any knowledge obtained from the server not
5541 obtained from the TLS negotiation itself. Patch contributed by Bill
5542 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005543
Georg Brandl3ee81df2008-05-17 18:14:43 +00005544- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005545 that the SMTP.starttls() caller no longer needs to call ehlo()
5546 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005547 does not claim to support starttls. Adds the
5548 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5549 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005603- itertools.chain() now has an alternate constructor,

5629 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5630 silently miscode subclasses of those types. Now, it raises a
5631 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005632

Georg Brandl3ee81df2008-05-17 18:14:43 +00005647 time so that opening a database previously created with the DB_DUP
5648 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5649 opens. Specifically: dictionary assignment to a DB object will
5650 replace all values for a given key when the database allows
5651 duplicate values. DB users should use DB.put(k, v) when they want
5652 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005653

5659 characters with ASCII value less than 32. Also, it correctly quotes
5660 dots only if they occur on a single line, as opposed to the previous
5661 behavior of quoting dots if they are the second character of any
5662 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005663

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005931- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005932 periodic threadstate and signal checking in tight loops. By
5933 default, this option is turned-off. It should only be enabled in
5934 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00005991
Georg Brandl3ee81df2008-05-17 18:14:43 +00005992- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5993 to ``PyTuple_SetItem``, it can be used to populate a brand new

6006
Georg Brandl3ee81df2008-05-17 18:14:43 +00006007- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6008 of w# format code incorrectly truncated the length to an int, even
6009 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6010 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006011
Georg Brandl3ee81df2008-05-17 18:14:43 +00006012- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6032
6033- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6034 outside of pystate.c and should not be necessary.
6035
Georg Brandl3ee81df2008-05-17 18:14:43 +00006036- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6037 absolute imports. In earlier versions they might have used relative
6038 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006039
Georg Brandl3ee81df2008-05-17 18:14:43 +00006040- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6041 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006042
Georg Brandl3ee81df2008-05-17 18:14:43 +00006043- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006068- Removed the macfs module. It had been deprecated since Python 2.5.
6069 This lead to the deprecation of macostools.touched() as it relied
6070 solely on macfs and was a no-op under OS X.
