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.

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,

Georg Brandlfee0f442010-05-22 21:26:21 +0000135- Issue #1533: Fix inconsistency in range function argument processing: any
136 non-float non-integer argument is now converted to an integer (if possible)
137 using its __int__ method. Previously, only small arguments were treated this

Georg Brandlfee0f442010-05-22 21:26:21 +0000147 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +0000148 benefit compared to the dynamic memory allocation fallback. Patch by

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000338 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

360Core and Builtins
361-----------------
362
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000363- Issue #7301: Add environment variable $PYTHONWARNINGS.
364
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000365- Issue #8329: Don't return the same lists from select.select when no fds are
366 changed.
367
Georg Brandlfee0f442010-05-22 21:26:21 +0000368- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000369 on 64-bit machines. The shift count for either left or right shift is
370 permitted to be up to sys.maxsize.
371
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000372- Ensure that tokenization of identifiers is not affected by locale.

377
Georg Brandlfee0f442010-05-22 21:26:21 +0000378- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
379 with a non-empty format string. This is an effort to future-proof user
380 code. If a derived class does not currently implement __format__ but later
381 adds its own __format__, it would most likely break user code that had
382 supplied a format string. This will be changed to a DeprecationWaring in
383 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000384
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000385- Issue #8268: Old-style classes (not just instances) now support weak

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000410- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000411 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

415
Georg Brandlfee0f442010-05-22 21:26:21 +0000416- Issue #8257: The Decimal construct now accepts a float instance directly,
417 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000418
419 >>> Decimal(1.1)
420 Decimal('1.100000000000000088817841970012523233890533447265625')
421
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000422- collections.Counter() now supports a subtract() method.
423
Georg Brandlfee0f442010-05-22 21:26:21 +0000424- The functools module now has a total_ordering() class decorator to simplify
425 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000426
Georg Brandlfee0f442010-05-22 21:26:21 +0000427- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +0000433- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
434 InvalidOperation instead of returning False. (Comparisons involving a quiet
435 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
436 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000437
Georg Brandlfee0f442010-05-22 21:26:21 +0000438- Issue #2531: Comparison operations between floats and Decimal instances now
439 return a result based on the numeric values of the operands; previously they
440 returned an arbitrary result based on the relative ordering of id(float) and
441 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000442
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000443- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000444 argument `-` which tells it to read files to compile from stdin. Each line is
445 read on demand and the named file is compiled immediately. (Original patch by
446 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000455- Comparisons using one of <, <=, >, >= between a complex instance and a
456 Fractions instance now raise TypeError instead of returning True/False. This
457 makes Fraction <=> complex comparisons consistent with int <=> complex, float
458 <=> complex, and complex <=> complex comparisons.

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

809 and add the additional members returned in an OSVERSIONINFOEX structure. The
810 new members are service_pack_major, service_pack_minor, suite_mask, and
811 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000813- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
814 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
815 returning NULL. The macro now returns a statically allocated empty string

826 strings,
827 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
828 numeric strings corresponding to subnormal values,
829 (3) a memory leak for some values large enough to cause overflow, and
830 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +0000858- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000859 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000865- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000866 file position when calling `truncate()`. It would previously change the file
867 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000868 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
869
Benjamin Petersone06f7112010-01-28 02:15:02 +0000870- UserDict is now a new-style class.
871
Georg Brandlba83f822010-03-14 09:50:54 +0000872- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
873 class used to represent files stored inside an archive. The new
874 implementation is significantly faster and can be wrapped in a
875 ``io.BufferedReader`` object for more speedups. It also solves an issue
876 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
877 Patch by Nir Aides.

885 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000886
Georg Brandlba83f822010-03-14 09:50:54 +0000887- Issue #7748: Since unicode values are supported for some metadata options in
888 Distutils, the DistributionMetadata get_* methods will now return an utf-8
889 encoded string for them. This ensures that the upload and register commands
890 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000892- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000893 headers in multipart/signed MIME parts, which fixes one of the sources of

966
Georg Brandlba83f822010-03-14 09:50:54 +0000967- The ``__complex__()`` method is now looked up on the class of instances to
968 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000970- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
971 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
972
Mark Dickinson1b34d252010-01-01 17:27:30 +0000973- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000974 DeprecationWarning when passed a float argument where an integer was expected.
975 These functions and methods now raise TypeError instead. The majority of the
976 effects of this change are in the extension modules, but some core functions
977 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
978 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00001161- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1162 decimal string that's guaranteed to round back to x under correct rounding
1163 (with round-half-to-even rounding mode). Previously it gave a string based on
1164 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1165 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1166 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001167
Georg Brandlba83f822010-03-14 09:50:54 +00001168- Issue #7117: On almost all platforms: float-to-string and string-to-float
1169 conversions within Python are now correctly rounded. Places these conversions
1170 occur include: str for floats and complex numbers; the float and complex
1171 constructors; old-style and new-style numeric formatting; serialization and
1172 deserialization of floats and complex numbers using marshal, pickle and json;
1173 parsing of float and imaginary literals in Python code; Decimal-to-float
1174 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001175
Georg Brandlba83f822010-03-14 09:50:54 +00001176 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1177 providing correctly-rounded strtod and dtoa C functions. This code is
1178 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1179 the C compiler. There may be a small number of platforms on which correct
1180 operation of this code cannot be guaranteed, so the code is not used: notably,
1181 this applies to platforms where the C double format is not IEEE 754 binary64,
1182 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1183 and Python's configure script is unable to determine how to change the FPU
1184 precision. On these platforms conversions use the platform strtod and dtoa,
1185 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001187- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1188 uses the correctly-rounded string <-> float conversions described above (when
1189 available), and so produces correctly rounded results that will display nicely
1190 under the float repr. There are two related small changes: (1) round now
1191 accepts any class with an ``__index__()`` method for its second argument (but
1192 no longer accepts floats for the second argument), and (2) an excessively
1193 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1194 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001341- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1342 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1343 but with at least one decimal point and with a default precision
1344 of 12. Previously, the behavior the same but with a default precision of 6.
1345 This more closely matches ``str()``, and reduces surprises when adding
1346 alignment flags to the empty presentation type. This also affects the new
1347 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00001487- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1488 existing .py counterpart, override the co_filename attributes of all code

1544
Georg Brandlba83f822010-03-14 09:50:54 +00001545- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1546 file objects with closefd=False. The file descriptor is still kept open but
1547 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00001571- On windows, ``os.chdir()`` given unicode was not working if
1572 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1573 this code path is really executed because I cannot move to such directory on
1574 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001576- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1577 element is temporarily replaced with an equivalent frozenset. But the
1578 eventual KeyError would always report the empty ``frozenset()`` as the missing
1579 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001599- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1600 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1601 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1602 of using the replace error handler in PyUnicode_DecodeUTF8().
1603
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001604- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001607- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

1609 gives improved memory leak detection when running under Valgrind, while taking
1610 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00002142- Issue #5679: The methods unittest.TestCase.addCleanup and doCleanups were
2143 added. addCleanup allows you to add cleanup functions that will be called
Michael Foord07ef4872009-05-02 22:43:34 +00002144 unconditionally (after setUp if setUp fails, otherwise after tearDown). This
2145 allows for much simpler resource allocation and deallocation during tests.

Michael Foord345b2fe2009-04-02 03:20:38 +00002160 and assertFalse messages are now useful. TestCase has a longMessage attribute.
2161 This defaults to False, but if set to True useful error messages are shown in
2162 addition to explicit messages passed to assert methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002437 the timestamp in the gzip stream. The default value remains the current time.

Georg Brandlba83f822010-03-14 09:50:54 +00002833 leak-chasing test runs give sensible results. The previous method of reaping
2834 threads could return successfully while some Thread objects were still
2835 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002852- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2853 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002854 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2855 the tests if DISPLAY is defined but can't be used.

2861 import both normal and optimised versions of modules. test_heapq and
2862 test_warnings have been adjusted to use it, tests for other modules with both
2863 C and Python implementations in the stdlib can be adjusted to use it over

2873 should cause a test to be skipped are now done using import_module from test
2874 support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002977- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2978 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2979 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2980 ``printf`` function, whereas PyString_FromFormat has an independent
2981 implementation and uses "%zd" on all platforms for size_t values.
2982 This makes a difference on win64, where ``printf`` needs "%Id" to display
2983 64bit values.

2989 object; previously an int would be returned for small values. the __long__

Antoine Pitrou0668c622008-08-26 22:42:08 +00003003 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3004 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3005 when given a tuple of classes as second argument, were looking up
3006 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3007 type object.

3125 wrapper for warnings.catch_warnings() that makes it easier to check
3126 that expected warning messages are being reported.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003146What's New in Python 2.6 beta 3?
3147================================
3148
Barry Warsaw07a4a382008-08-21 01:15:08 +00003149*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003150
3151Core and Builtins
3152-----------------
3153
Guido van Rossumf8402962008-08-20 15:01:50 +00003154- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3155 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3156 extensions do not automatically benefit from the class attribute
3157 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3158 to their tp_flags field if they care. This is a backwards
3159 compatibility feature; in 3.0, all types will use the cache by
3160 default.
3161
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003162- Keyword arguments can now follow starred arguments. (``f(a, *args,
3163 keyword=23)`` is now valid syntax.)
3164
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003165- ctypes function pointers that are COM methods have a boolean True
3166 value again.
3167
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003168- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3169 by denying s# to parse objects that have a releasebuffer procedure,
3170 and introducing s*.
3171
Georg Brandl1e13ea92008-08-11 09:07:59 +00003172- Issue #3537: Fix an assertion failure when an empty but presized dict
3173 object was stored in the freelist.
3174
Mark Dickinsonb6467572008-08-04 21:30:09 +00003175- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3176 ValueError consistently across platforms.
3177
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003178- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3179 (64bit Unix, for example), unichr() would truncate its argument and return
3180 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3181
Neal Norwitze7d8be82008-07-31 17:17:14 +00003182- Apply security patches from Apple.
3183
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003184- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3185 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3186
Antoine Pitrou92f82162008-07-25 22:22:08 +00003187- Issue #1819: function calls with several named parameters are now on
3188 average 35% faster (as measured by pybench).
3189
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003190- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3191 the python debugger steps into a class statement: the free variables (local
3192 variables defined in an outer scope) would be deleted from the outer scope.
3193
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003194- Issue #2620: Overflow checking when allocating or reallocating memory
3195 was not always being done properly in some python types and extension
3196 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3197 all been updated to perform better checks and places in the code that
3198 would previously leak memory on the error path when such an allocation
3199 failed have been fixed.
3200
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003201Library
3202-------
3203
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003204- Issue #3612: Added some missing basic types in ctypes.wintypes.
3205
Benjamin Petersone977ad42008-08-20 01:42:01 +00003206- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3207 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3208
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003209- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3210 version reported by these tools does not necessarily follow the python
3211 version numbering scheme, so the module is less strict when parsing it.
3212
Nick Coghlanf70385a2008-08-18 12:42:46 +00003213- Issue #2235: Added Py3k warnings for types which will become unhashable
3214 under the stricter __hash__ inheritance rules in 3.0. Several types
3215 which did not meet the rules for hash invariants and were already
3216 unhashable in 3.0 have now been explicitly flagged as unhashable in
3217 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3218 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3219
Brett Cannon88f801d2008-08-18 00:46:22 +00003220- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3221 imported into the module but exposed as part of the module's API.
3222
Brett Cannon7b96f072008-08-18 00:41:11 +00003223- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3224
Brett Cannon46225e72008-08-18 00:36:52 +00003225- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3226
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003227- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3228
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003229- Issue #3575: Incremental decoder's decode function now takes bytearray
3230 by using 's*' instead of 't#'.
3231
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003232- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003233 fails unicode conversion on 2nd parameter. (windows only)
3234
Facundo Batista94f243a2008-08-17 03:38:39 +00003235- Issue 2464. urllib2 now supports a malformation in the URL received
3236 in a redirect.
3237
Brett Cannonabe423e2008-08-16 21:47:07 +00003238- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003239 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003240
Facundo Batistaeb90b782008-08-16 14:44:07 +00003241- Issue #2776: fixed small issue when handling an URL with double slash
3242 after a 302 response in the case of not going through a proxy.
3243
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003244- Issue #2676: in the email package, content-type parsing was hanging on
3245 pathological input because of quadratic or exponential behaviour of a
3246 regular expression.
3247
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003248- Issue #3476: binary buffered reading through the new "io" library is now
3249 thread-safe.
3250
Brett Cannonbf3157b2008-08-14 05:00:03 +00003251- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3252 since mimetools itself is deprecated. Because modules are cached, all
3253 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3254
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003255- Issue #3134: shutil referenced undefined WindowsError symbol.
3256
Robert Schuppenies14646332008-08-10 11:01:53 +00003257- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3258 menu entries were not deleted.
3259
Brett Cannon83e81842008-08-09 23:30:55 +00003260- Copied the implementation of reduce() to _functools.reduce() to have a
3261 version that did not raise a DeprecationWarning under -3.
3262
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003263- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3264 a MemoryError rather than silently stop the iteration.
3265
Guido van Rossum59ce9012008-08-09 14:55:34 +00003266- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3267 to _sre.compile() will now be rejected. This should not affect anybody
3268 since the re.compile() function never generates invalid re-bytecode.
3269
Skip Montanaroa032bf42008-08-08 22:52:51 +00003270- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3271 upon first access it can be automatically initialized from the csv file if
3272 it wasn't initialized during instantiation.
3273
Brett Cannon3aa2a492008-08-06 22:28:09 +00003274- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3275 the reload() built-in has been removed.
3276
Brett Cannon7e30b672008-08-04 21:52:25 +00003277- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003278 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3282 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3283 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003284
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003285- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3286 raised an AttributeError.
3287
Benjamin Peterson01a24322008-07-28 23:35:27 +00003288- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003289 asking for a specific length. This problem only affected files opened
3290 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003291
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003292- Issue #3449: Update decimal module to use most recent specification
3293 (v. 1.68) and tests (v. 2.58) from IBM.
3294
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003295- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3296
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003297- Issue 1592: Improve error reporting when operations are attempted

3303
3304- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3305 invalid arguments.
3306
3307- Issue #3302: Fix several crashes when calling locale's gettext functions
3308 with None arguments.
3309
3310- Issue #3389: Allow resolving dotted names for handlers in logging
3311 configuration files.
3312
3313- Deprecate the sunaudio module for removal in Python 3.0.
3314
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003315- Issue #3394: zipfile.writestr sets external attributes when passed a
3316 file name rather than a ZipInfo instance, so files are extracted with
3317 mode 0600 rather than 000 under Unix.
3318
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003319- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3320 argument in python 2.5, this broke code that subclassed Popen to include its
3321 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3330
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003331- Issue #2235: the C API function PyObject_HashNotImplemented and its
3332 interaction with the tp_hash slot (added in 2.6b2) are now documented
3333
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003334- Issue #643841: The language reference now provides more detailed
3335 coverage of the lookup process for special methods. The disclaimers
3336 regarding lack of coverage of new-style classes have also been
3337 removed, since the coverage is now fairly reasonable.

3341================================
3342
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003343*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003345Core and Builtins
3346-----------------
3347
Georg Brandl3e483f62008-07-16 22:57:41 +00003348- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3349 its methods now allow for items objects that can be converted to
3350 an integer using operator.index().
3351
Mark Dickinson64b7e502008-07-16 09:40:03 +00003352- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3353 produced a ValueError instead of giving the correct float.
3354
Eric Smitha5fa5a22008-07-16 00:11:49 +00003355- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3356 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3357
Mark Dickinson7103aa42008-07-15 19:08:33 +00003358- Issue #3008: the float type has a new instance method 'float.hex'
3359 and a new class method 'float.fromhex' to convert floating-point
3360 numbers to and from hexadecimal strings, respectively.
3361
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003362- Issue #2235: __hash__ is once again inherited by default. To allow
3363 collections.Hashable to remain meaningful in the presence of the
3364 default hash implementation (object.__hash__), it is now possible
3365 to explicit block inheritance of hash by setting __hash__=None at
3366 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3367 level.
3368
Nick Coghlanb028f502008-07-13 14:52:36 +00003369- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3370 the parent module cannot be found while performing an absolute import.
3371 This means that an incorrectly defined __package__ attribute will
3372 now only prevent relative imports in that module rather than causing
3373 all imports from that module to fail.
3374
Nick Coghlan14ff9942008-07-08 14:21:42 +00003375- Issue #2517: Allow unicode messages in Exceptions again by correctly
3376 bypassing the instance dictionary when looking up __unicode__ on
3377 new-style classes.
3378
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003379- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3380 set to a custom object whose write() method happens to install
3381 another file in sys.stdout.
3382
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003383- Issue #3088: Corrected a race condition in classes derived from

3385 another thread's dictionary.
3386
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003387- Issue #3004: Minor change to slice.indices(): the start and stop
3388 arguments are now treated identically, making the behaviour easier
3389 to describe and understand. For example, slice(None, -10,
3390 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3391 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3392 10, -1).
3393
Georg Brandl278fc502008-07-19 12:46:12 +00003394- Issue #3219: Calling a function with repeated keyword arguments,
3395 f(a=2, a=23), would not cause a syntax error. This was a regression
3396 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00003846 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003847
3848 This is controlled by the configure argument ``--with-universal-archs``:
3849
3850 - ``--with-universal-archs=all``: install 4-way universal
3851
3852 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3853
3854 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3855

Georg Brandl3ee81df2008-05-17 18:14:43 +00003908- Issue #1631171: Re-implement the 'warnings' module in C (the
3909 original Python code has been kept as backup). This will allow for
3910 using the 'warning's machinery in such places as the parser where
3911 use of pure Python code is not possible. Both the ``showarning()``
3912 and ``formatwarning()`` gain an optional 'line' argument which is
3913 not called by default for backwards-compatibility reasons. Setting
3914 ``warnings.showwarning()`` to an implementation that lacks support
3915 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003978- Issue #2550: The approach used by client/server code for obtaining
3979 ports to listen on in network-oriented tests has been refined in an
3980 effort to facilitate running multiple instances of the entire
3981 regression test suite in parallel without issue.
3982 test_support.bind_port() has been fixed such that it will always
3983 return a unique port -- which wasn't always the case with the
3984 previous implementation, especially if socket options had been set
3985 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3986 new implementation of bind_port() will actually raise an exception
3987 if it is passed an AF_INET/SOCK_STREAM socket with either the
3988 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3989 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3990 the socket it's been passed. This currently only applies to
3991 Windows. This option prevents any other sockets from binding to the
3992 host/port we've bound to, thus removing the possibility of the
3993 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3994 when a second SOCK_STREAM socket binds and accepts to a host/port
3995 that's already been bound by another socket. The optional preferred
3996 port parameter to bind_port() has been removed. Under no
3997 circumstances should tests be hard coding ports!
3998
3999 test_support.find_unused_port() has also been introduced, which will
4000 pass a temporary socket object to bind_port() in order to obtain an
4001 unused port. The temporary socket object is then closed and
4002 deleted, and the port is returned. This method should only be used
4003 for obtaining an unused port in order to pass to an external program
4004 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4005 a parameter to a server-oriented class that doesn't give you direct
4006 access to the underlying socket used.
4007
4008 Finally, test_support.HOST has been introduced, which should be used
4009 for the host argument of any relevant socket calls (i.e. bind and
4010 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004011
4012 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004013 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004014 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4015 test_asynchat and test_socket_ssl.
4016
Georg Brandl3ee81df2008-05-17 18:14:43 +00004017 It is now possible for multiple instances of the regression test
4018 suite to run in parallel without issue.

Thomas Heller78b8f442008-03-05 14:53:39 +00004222- The bundled libffi copy is now in sync with the recently released
4223 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004224 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
4225 files are used. On all linux systems the --with-system-ffi
4226 configure option defaults to "yes".

4285-----------------
4286
Fred Drakea8ee94b2008-03-01 02:45:07 +00004287- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004288 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004289
Georg Brandlad61bc82008-02-23 15:11:18 +00004290- Issue #2067: file.__exit__() now calls subclasses' close() method.
4291
4292- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004293
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004294- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004295 issue 215555 for a discussion.
4296
Eric Smitha73fbe72008-02-23 03:09:44 +00004297- Added the future_builtins module, which contains hex() and oct().
4298 These are the PEP 3127 version of these functions, designed to be
4299 compatible with the hex() and oct() builtins from Python 3.0. They
4300 differ slightly in their output formats from the existing, unchanged
4301 Python 2.6 builtins. The expected usage of the future_builtins
4302 module is:
4303 from future_builtins import hex, oct
4304
Eric Smith7ef40bf2008-02-20 23:34:22 +00004305- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4306 exponents for exponents with absolute value < 100. Follows C99
4307 standard. This is a change on Windows, which would use 3 digits.
4308 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4309 so that any alterations it does to the resulting string will be
4310 available in stringlib/formatter.h (for float.__format__).
4311
Eric Smith5a3c1352008-02-19 13:21:56 +00004312- Implemented PEP 3101, Advanced String Formatting. This adds a new
4313 builtin format(); a format() method for str and unicode; a
4314 __format__() method to object, str, unicode, int, long, float, and
4315 datetime; the class string.Formatter; and the C API
4316 PyObject_Format().
4317
Georg Brandl3ee81df2008-05-17 18:14:43 +00004318- Fixed several potential crashes, all caused by specially crafted
4319 __del__ methods exploiting objects in temporarily inconsistent
4320 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004321
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004322- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004323 prevent a possible crash: an Abstract Base Class would try to access
4324 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004325
Georg Brandl3ee81df2008-05-17 18:14:43 +00004326- Fixed repr() and str() of complex numbers with infinity or nan as
4327 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004328
Georg Brandl3ee81df2008-05-17 18:14:43 +00004329- Clear all free lists during a gc.collect() of the highest generation
4330 in order to allow pymalloc to free more arenas. Python may give back
4331 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004332
Georg Brandl3ee81df2008-05-17 18:14:43 +00004333- Issue #2045: Fix an infinite recursion triggered when printing a
4334 subclass of collections.defaultdict, if its default_factory is set
4335 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004336
Christian Heimesf75dbef2008-02-08 00:11:31 +00004337- Fixed a minor memory leak in dictobject.c. The content of the free
4338 list was not freed on interpreter shutdown.
4339
Georg Brandl21e99f42010-03-07 15:23:59 +00004340- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004341 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004342
Georg Brandl3ee81df2008-05-17 18:14:43 +00004343- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4344 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004345 to compact the internal free lists of pre-allocted ints and floats.
4346
Georg Brandl3ee81df2008-05-17 18:14:43 +00004347- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4348 calls. Python expected the return type int but the fork familie
4349 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004350
Georg Brandl3ee81df2008-05-17 18:14:43 +00004351- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4352 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004353
Georg Brandl3ee81df2008-05-17 18:14:43 +00004354- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4355 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004356

Georg Brandl3ee81df2008-05-17 18:14:43 +00004360- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4361 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004362
Georg Brandl3ee81df2008-05-17 18:14:43 +00004363- Patch #1473257: generator objects gain a gi_code attribute. This is
4364 the same object as the func_code attribute of the function that
4365 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004366
Georg Brandl3ee81df2008-05-17 18:14:43 +00004367- Issue #1920: "while 0" statements were completely removed by the
4368 compiler, even in the presence of an "else" clause, which is
4369 supposed to be run when the condition is false. Now the compiler
4370 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004371
Guido van Rossumeead05f2008-01-24 18:21:02 +00004372- A few crashers fixed: weakref_in_del.py (issue #1377858);
4373 loosing_dict_ref.py (issue #1303614, test67.py);
4374 borrowed_ref_[34].py (not in tracker).
4375
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004376- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004377 suppressed while an extension is loaded by calling SetErrorMode in
4378 dynload_win.c. The error is still reported properly.
4379
Georg Brandl3ee81df2008-05-17 18:14:43 +00004380- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004381 several extension methods and modules do not work without unicode
4382 support.
4383
Georg Brandl26543b12008-01-21 18:36:51 +00004384- Issue #1882: when compiling code from a string, encoding cookies in the
4385 second line of code were not always recognized correctly.
4386
Georg Brandl14404b62008-01-19 19:27:05 +00004387- Issue #1679: "0x" was taken as a valid integer literal.
4388
Georg Brandl6caad7d2008-01-26 14:19:22 +00004389- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004390 added.
4391
Christian Heimesc94e2b52008-01-14 04:13:37 +00004392- sys.float_info / PyFloat_GetInfo: The floating point information
4393 object was converted from a dict to a specialized structseq object.
4394
Georg Brandl3ee81df2008-05-17 18:14:43 +00004395- Patch #1816: Added sys.flags structseq. It exposes the status of
4396 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004397
Georg Brandl3ee81df2008-05-17 18:14:43 +00004398- Objects/structseq.c: Implemented new structseq representation. The
4399 patch makes structseqs (e.g. the return value of os.stat) more
4400 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004401
Georg Brandl3ee81df2008-05-17 18:14:43 +00004402- Patch #1700288: added a type attribute cache that caches method

4411 envvar and sys.dont_write_bytecode attribute. All these can be set
4412 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004413
Georg Brandl3ee81df2008-05-17 18:14:43 +00004414- Improve some exception messages when Windows fails to load an
4415 extension module. Now we get for example '%1 is not a valid Win32
4416 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004423- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004424 and INF. float("nan"), float("inf") and float("-inf") now work on
4425 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004426
Georg Brandl3ee81df2008-05-17 18:14:43 +00004427- Compiler now generates simpler and faster code for dictionary
4428 literals. The oparg for BUILD_MAP now indicates an estimated
4429 dictionary size. There is a new opcode, STORE_MAP, for adding
4430 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004459- Patch #1739468: Directories and zipfiles containing a __main__.py
4460 file can now be directly executed by passing their name to the
4461 interpreter. The directory/zipfile is automatically inserted as the
4462 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004464- Issue #1265: Fix a problem with sys.settrace, if the tracing
4465 function uses a generator expression when at the same time the
4466 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004467
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004468- sets and frozensets now have an isdisjoint() method.

Neal Norwitz44f326e2007-10-05 05:29:17 +00004472- Fix warnings found by the new version of the Coverity checker.
4473
Georg Brandl21e99f42010-03-07 15:23:59 +00004474- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004475 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4476 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004477
Georg Brandl3ee81df2008-05-17 18:14:43 +00004478- Issue #1686386: Tuple's tp_repr did not take into account the
4479 possibility of having a self-referential tuple, which is possible
4480 from C code. Nor did object's tp_str consider that a type's tp_str
4481 could do something that could lead to an inifinite recursion.
4482 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4483 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004484
Georg Brandl3ee81df2008-05-17 18:14:43 +00004485- Issue #1164: It was possible to trigger deadlock when using the
4486 'print' statement to write to a file since the GIL was not released
4487 as needed. Now PyObject_Print() does the right thing along with
4488 various tp_print implementations of the built-in types and those in
4489 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004490
Georg Brandl3ee81df2008-05-17 18:14:43 +00004491- Issue #1147: Exceptions were directly allowing string exceptions in
4492 their throw() method even though string exceptions no longer
4493 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004494
Georg Brandl3ee81df2008-05-17 18:14:43 +00004495- Issue #1096: Prevent a segfault from getting the repr of a very
4496 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004497
Brett Cannon1e534b52007-09-07 04:18:30 +00004498- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004499 PyObject_Call() never calling back out to Python code to trigger
4500 recursion depth updates/checks. Required the creation of a static
4501 RuntimeError instance in case normalizing an exception put the
4502 recursion check value past its limit. Fixes crashers
4503 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004504
Georg Brandl3ee81df2008-05-17 18:14:43 +00004505- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004518- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004519 __*__ attributes. (Some already existed, e.g., __doc__ and
4520 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004521
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004522- Add -3 option to the interpreter to warn about features that are
4523 deprecated and will be changed/removed in Python 3.0.
4524
Georg Brandl2134e752007-05-21 20:34:16 +00004525- Patch #1686487: you can now pass any mapping after '**' in function
4526 calls.
4527
Collin Winter62903052007-05-18 23:11:24 +00004528- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004529 "except E as target:". This is to provide forwards compatibility
4530 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004531
Brett Cannon229cee22007-05-05 01:34:02 +00004532- Deprecate BaseException.message as per PEP 352.
4533
Georg Brandl3ee81df2008-05-17 18:14:43 +00004534- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004535 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004536
Vinay Sajip8549ce32007-05-06 17:53:37 +00004537- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004538 setting a plain string, ie don't expand to single letter identifiers.
4539
Raymond Hettinger13936692007-04-11 18:40:58 +00004540- Request #1191699: Slices can now be pickled.
4541
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004542- Request #1193128: str.translate() now allows a None argument for
4543 translations that only remove characters without re-mapping the
4544 remaining characters.
4545
Georg Brandl5cb76c12007-03-21 09:00:39 +00004546- Patch #1682205: a TypeError while unpacking an iterable is no longer

4550
Guido van Rossum143b5642007-03-23 04:58:42 +00004551- Bug #1683368: The object.__init__() and object.__new__() methods are
4552 now stricter in rejecting excess arguments. The only time when
4553 either allows excess arguments is when it is not overridden and the
4554 other one is. For backwards compatibility, when both are
4555 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004556 warning later). Also, type.__init__() insists on the same signature
4557 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004558
Georg Brandl3ee81df2008-05-17 18:14:43 +00004559- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4560 object to complex using its __complex__() method before falling back
4561 to the __float__() method. Therefore, the functions in the cmath
4562 module now can operate on objects that define a __complex__()
4563 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004564
Georg Brandl3ee81df2008-05-17 18:14:43 +00004565- Patch #1623563: allow __class__ assignment for classes with
4566 __slots__. The old and the new class are still required to have the
4567 same slot names.

4573 ``object.__reduce_ex__()`` is called with an object that is faking
4574 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004575
Georg Brandl3ee81df2008-05-17 18:14:43 +00004576- Patch #1680015: Don't modify __slots__ tuple if it contains an

4580
Georg Brandl7b9c5552007-03-12 14:30:05 +00004581- Bug #1678647: write a newline after printing an exception in any
4582 case, even when converting the value to a string failed.
4583
Georg Brandl871f1bc2007-03-12 13:17:36 +00004584- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004585 its argument, if it exists. If not, it will work like before. This
4586 allows customizing the output of dir() in the presence of a
4587 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004595- Patch #1491866: change the complex() constructor to allow
4596 parthensized forms. This means complex(repr(x)) now works instead of
4597 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004598
Georg Brandlaa2321b2007-03-07 00:40:28 +00004599- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004600 makes the filenames the warning module prints much more sensible
4601 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004602

Georg Brandl0fca97a2007-03-05 22:28:08 +00004614- Patch #1674228: when assigning a slice (old-style), check for the
4615 sq_ass_slice instead of the sq_slice slot.
4616
Georg Brandl3ee81df2008-05-17 18:14:43 +00004617- When printing an unraisable error, don't print exceptions. before
4618 the name. This duplicates the behavior whening normally printing
4619 exceptions.

5247 -- the failure just occurred later, with a more cumbersome
5248 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005529- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5530 with RFC 3207 and forgets any knowledge obtained from the server not
5531 obtained from the TLS negotiation itself. Patch contributed by Bill
5532 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005533
Georg Brandl3ee81df2008-05-17 18:14:43 +00005534- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005535 that the SMTP.starttls() caller no longer needs to call ehlo()
5536 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005537 does not claim to support starttls. Adds the
5538 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5619 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5620 silently miscode subclasses of those types. Now, it raises a
5621 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005622

Georg Brandl3ee81df2008-05-17 18:14:43 +00005637 time so that opening a database previously created with the DB_DUP
5638 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5639 opens. Specifically: dictionary assignment to a DB object will
5640 replace all values for a given key when the database allows
5641 duplicate values. DB users should use DB.put(k, v) when they want
5642 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005643

5649 characters with ASCII value less than 32. Also, it correctly quotes
5650 dots only if they occur on a single line, as opposed to the previous
5651 behavior of quoting dots if they are the second character of any
5652 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005653

5975-----
5976
Georg Brandl3ee81df2008-05-17 18:14:43 +00005977- Unified naming convention for free lists and their limits. All free
5978 lists in Object/ are named ``free_list``, the counter ``numfree``

5980 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005981
Georg Brandl3ee81df2008-05-17 18:14:43 +00005982- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5983 to ``PyTuple_SetItem``, it can be used to populate a brand new

5996
Georg Brandl3ee81df2008-05-17 18:14:43 +00005997- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5998 of w# format code incorrectly truncated the length to an int, even
5999 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6000 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006001
Georg Brandl3ee81df2008-05-17 18:14:43 +00006002- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6020- Fix some leftovers from the conversion from int to Py_ssize_t
6021 (relevant to strings and sequences of more than 2**31 items).
6022
6023- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6024 outside of pystate.c and should not be necessary.
6025
Georg Brandl3ee81df2008-05-17 18:14:43 +00006026- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6027 absolute imports. In earlier versions they might have used relative
6028 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006029
Georg Brandl3ee81df2008-05-17 18:14:43 +00006030- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6031 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006032
Georg Brandl3ee81df2008-05-17 18:14:43 +00006033- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

6041 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6042 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6043 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006044

Georg Brandl3ee81df2008-05-17 18:14:43 +00006058- Removed the macfs module. It had been deprecated since Python 2.5.
6059 This lead to the deprecation of macostools.touched() as it relied
6060 solely on macfs and was a no-op under OS X.
