Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000186- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
187 start byte and the continuation byte(s) are now considered invalid, instead
188 of the number of bytes specified by the start byte.
189 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
190 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
191 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
192 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000200- Issue #8748: Fix two issues with comparisons between complex and integer
201 objects. (1) The comparison could incorrectly return True in some cases
202 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
203 (2) The comparison raised an OverflowError for large integers, leading
204 to unpredictable exceptions when combining integers and complex objects
205 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +0000207- Issue #5211: Implicit coercion for the complex type is now completely

345 non-float non-integer argument is now converted to an integer (if possible)

Benjamin Petersonfbac6c12010-04-10 16:22:05 +0000567*Release date: 2010-04-10*
Benjamin Peterson5da7e7c2010-03-06 22:44:07 +0000568
569Core and Builtins
570-----------------
571
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000572- Issue #7301: Add environment variable $PYTHONWARNINGS.
573
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000574- Issue #8329: Don't return the same lists from select.select when no fds are
575 changed.
576
Georg Brandlfee0f442010-05-22 21:26:21 +0000577- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000578 on 64-bit machines. The shift count for either left or right shift is
579 permitted to be up to sys.maxsize.
580
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000581- Ensure that tokenization of identifiers is not affected by locale.
582
Georg Brandlfee0f442010-05-22 21:26:21 +0000583- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +0000584
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000585- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
586
Georg Brandlfee0f442010-05-22 21:26:21 +0000587- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
588 with a non-empty format string. This is an effort to future-proof user
589 code. If a derived class does not currently implement __format__ but later
590 adds its own __format__, it would most likely break user code that had
591 supplied a format string. This will be changed to a DeprecationWaring in
592 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000593
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000594- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinnerc7790ed2010-03-22 12:36:28 +0000600- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +0000601
Benjamin Peterson96545892010-03-21 20:21:00 +0000602- Issue #6474: Make error message from passing an inadequate number of keyword
603 arguments to a function correct.
604
Benjamin Peterson0dee9c12010-03-17 20:41:42 +0000605- Issue #8164: Don't allow lambda functions to have a docstring.

Victor Stinner66644262010-03-10 22:30:19 +0000607- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +0000608 (SIGINT). If an error occurs while importing the site module, the error is
609 printed and Python exits. Initialize the GIL before importing the site

618
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000619- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000620 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
621 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000622
Benjamin Peterson76a23c12010-04-04 23:23:22 +0000623- Issue #8310: Allow dis to examine new style classes.
624
Georg Brandlfee0f442010-05-22 21:26:21 +0000625- Issue #8257: The Decimal construct now accepts a float instance directly,
626 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000627
628 >>> Decimal(1.1)
629 Decimal('1.100000000000000088817841970012523233890533447265625')
630
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000631- collections.Counter() now supports a subtract() method.
632
Georg Brandlfee0f442010-05-22 21:26:21 +0000633- The functools module now has a total_ordering() class decorator to simplify
634 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000635
Georg Brandlfee0f442010-05-22 21:26:21 +0000636- The functools module also adds cmp_to_key() as a tool to transition old-style
637 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000638
Georg Brandlfee0f442010-05-22 21:26:21 +0000639- Issue #8294: The Fraction constructor now accepts Decimal and float instances
640 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000641
Georg Brandlfee0f442010-05-22 21:26:21 +0000642- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
643 InvalidOperation instead of returning False. (Comparisons involving a quiet
644 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
645 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000646
Georg Brandlfee0f442010-05-22 21:26:21 +0000647- Issue #2531: Comparison operations between floats and Decimal instances now
648 return a result based on the numeric values of the operands; previously they
649 returned an arbitrary result based on the relative ordering of id(float) and
650 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000651
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000652- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000653 argument `-` which tells it to read files to compile from stdin. Each line is
654 read on demand and the named file is compiled immediately. (Original patch by
655 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000656
Georg Brandlfee0f442010-05-22 21:26:21 +0000657- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000660- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
661 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000662 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000663
Georg Brandlfee0f442010-05-22 21:26:21 +0000664- Comparisons using one of <, <=, >, >= between a complex instance and a
665 Fractions instance now raise TypeError instead of returning True/False. This
666 makes Fraction <=> complex comparisons consistent with int <=> complex, float
667 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000668

677
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000678- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000679 didn't support chflags() (for example ZFS under FreeBSD). The error is now
680 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000681
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000682- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
683 deprecated.
684
Georg Brandlfee0f442010-05-22 21:26:21 +0000685- Issue #7860: platform.uname now reports the correct 'machine' type when Python
686 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +0000687

Antoine Pitroueee91cd2010-03-26 19:27:16 +0000698- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
699 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
700 reads and writes are always retried by OpenSSL itself.

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000722- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000723 for ``TimedRotatingFileHandler`` by using the modification time of an existing
724 log file to compute the next rollover time. If the log file does not exist,
725 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000726
Georg Brandlba83f822010-03-14 09:50:54 +0000727- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +0000735- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
736 a base64 transfer-encoded payload *after* decoding it; it no longer does.
737 This is a behavior change, so email's minor version number is now bumped, to
738 version 4.0.2, for the 2.7 release.

Georg Brandlba83f822010-03-14 09:50:54 +0000771- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
772 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
773 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +0000774 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
775 inconsistent: __int__ was used for some integer codes but not for others, and
776 the set of integer codes for which it was used differed between native packing
777 and standard packing.)

1034 including:
Mark Dickinson8efef5c2010-01-12 22:23:56 +00001035
Georg Brandlba83f822010-03-14 09:50:54 +00001036 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
1037 strings,
1038 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1039 numeric strings corresponding to subnormal values,
1040 (3) a memory leak for some values large enough to cause overflow, and
1041 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00001080 file position when calling `truncate()`. It would previously change the file
1081 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001082 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1085 class used to represent files stored inside an archive. The new
1086 implementation is significantly faster and can be wrapped in a

1088 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1176Core and Builtins
1177-----------------
1178
Georg Brandlba83f822010-03-14 09:50:54 +00001179- The ``__complex__()`` method is now looked up on the class of instances to
1180 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001181
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001182- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1183 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1184
Mark Dickinson1b34d252010-01-01 17:27:30 +00001185- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001186 DeprecationWarning when passed a float argument where an integer was expected.
1187 These functions and methods now raise TypeError instead. The majority of the
1188 effects of this change are in the extension modules, but some core functions
1189 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1190 and many unicode/str methods.

1201 used to drop the time part of the result.
1202
Georg Brandlba83f822010-03-14 09:50:54 +00001203- Issue #1811: Improve accuracy and cross-platform consistency for true division
1204 of integers: the result of a/b is now correctly rounded for ints a and b (at
1205 least on IEEE 754 platforms), and in particular does not depend on the
1206 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001207
Georg Brandlba83f822010-03-14 09:50:54 +00001208- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00001213 executables on OSX.
1214
Georg Brandlba83f822010-03-14 09:50:54 +00001215 These executables now work properly with the arch(1) command: ``arch -ppc
1216 python`` will start a universal binary version of python in PPC mode (unlike
1217 previous releases).

1357 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001358

Georg Brandlba83f822010-03-14 09:50:54 +00001373- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1374 decimal string that's guaranteed to round back to x under correct rounding
1375 (with round-half-to-even rounding mode). Previously it gave a string based on
1376 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1377 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1378 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001379
Georg Brandlba83f822010-03-14 09:50:54 +00001380- Issue #7117: On almost all platforms: float-to-string and string-to-float
1381 conversions within Python are now correctly rounded. Places these conversions
1382 occur include: str for floats and complex numbers; the float and complex
1383 constructors; old-style and new-style numeric formatting; serialization and
1384 deserialization of floats and complex numbers using marshal, pickle and json;
1385 parsing of float and imaginary literals in Python code; Decimal-to-float
1386 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001387
Georg Brandlba83f822010-03-14 09:50:54 +00001388 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1389 providing correctly-rounded strtod and dtoa C functions. This code is
1390 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1391 the C compiler. There may be a small number of platforms on which correct
1392 operation of this code cannot be guaranteed, so the code is not used: notably,
1393 this applies to platforms where the C double format is not IEEE 754 binary64,
1394 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1395 and Python's configure script is unable to determine how to change the FPU
1396 precision. On these platforms conversions use the platform strtod and dtoa,
1397 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001399- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1400 uses the correctly-rounded string <-> float conversions described above (when
1401 available), and so produces correctly rounded results that will display nicely
1402 under the float repr. There are two related small changes: (1) round now
1403 accepts any class with an ``__index__()`` method for its second argument (but
1404 no longer accepts floats for the second argument), and (2) an excessively
1405 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1406 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001549 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1550 (2) parsing of strings representing infinities and nans was locale aware; and
1551 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001553- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1554 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1555 but with at least one decimal point and with a default precision
1556 of 12. Previously, the behavior the same but with a default precision of 6.
1557 This more closely matches ``str()``, and reduces surprises when adding
1558 alignment flags to the empty presentation type. This also affects the new
1559 complex.__format__ in the same way.
1560
1561- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00001742- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1743 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1744 instances. On a typical machine this saves 3 bytes of memory (on average) per
1745 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001747- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

1756
Georg Brandlba83f822010-03-14 09:50:54 +00001757- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1758 file objects with closefd=False. The file descriptor is still kept open but
1759 the file object behaves like a closed file. The ``FileIO`` object also got a
1760 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001780- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001783- On windows, ``os.chdir()`` given unicode was not working if

1785 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00001788- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1789 element is temporarily replaced with an equivalent frozenset. But the
1790 eventual KeyError would always report the empty ``frozenset()`` as the missing
1791 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001811- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1812 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1813 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1814 of using the replace error handler in PyUnicode_DecodeUTF8().
1815
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001816- Issue #3739: The unicode-internal encoder now reports the number of characters

1818
Georg Brandlba83f822010-03-14 09:50:54 +00001819- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1820 allocator will be automatically disabled when running under Valgrind. This
1821 gives improved memory leak detection when running under Valgrind, while taking
1822 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003187- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3188
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003189- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3190 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3191 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3192 ``printf`` function, whereas PyString_FromFormat has an independent
3193 implementation and uses "%zd" on all platforms for size_t values.
3194 This makes a difference on win64, where ``printf`` needs "%Id" to display
3195 64bit values.
3196
Benjamin Peterson97179b02008-09-09 20:55:01 +00003197- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003200- Issue #3777: long() applied to a float object now always return a long
3201 object; previously an int would be returned for small values. the __long__
3202 method is allowed to return either an int or a long, but the behaviour of
3203 float objects should not change to respect backward compatibility.
3204
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003205- Issue #3751: str.rpartition would perform a left-partition when called with
3206 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003211 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003212 was correctly parsed but parsing of subsequent arguments failed.
3213
Vinay Sajip35e3b032008-09-01 14:33:59 +00003214- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003215 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3216 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3217 when given a tuple of classes as second argument, were looking up
3218 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3219 type object.
3220
Neal Norwitz18aa3882008-08-24 05:04:52 +00003221- Fix crashes on memory allocation failure found with failmalloc.

3290 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3291 for catch_warnings() also led to an improvement in the raising of a

3364-----------------
3365
Guido van Rossumf8402962008-08-20 15:01:50 +00003366- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3367 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3368 extensions do not automatically benefit from the class attribute
3369 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3370 to their tp_flags field if they care. This is a backwards
3371 compatibility feature; in 3.0, all types will use the cache by
3372 default.
3373
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003374- Keyword arguments can now follow starred arguments. (``f(a, *args,
3375 keyword=23)`` is now valid syntax.)
3376
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003377- ctypes function pointers that are COM methods have a boolean True
3378 value again.
3379
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003380- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3381 by denying s# to parse objects that have a releasebuffer procedure,
3382 and introducing s*.
3383
Georg Brandl1e13ea92008-08-11 09:07:59 +00003384- Issue #3537: Fix an assertion failure when an empty but presized dict
3385 object was stored in the freelist.
3386
Mark Dickinsonb6467572008-08-04 21:30:09 +00003387- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3388 ValueError consistently across platforms.
3389
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003390- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3391 (64bit Unix, for example), unichr() would truncate its argument and return
3392 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3393
Neal Norwitze7d8be82008-07-31 17:17:14 +00003394- Apply security patches from Apple.
3395
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003396- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

3398
Antoine Pitrou92f82162008-07-25 22:22:08 +00003399- Issue #1819: function calls with several named parameters are now on
3400 average 35% faster (as measured by pybench).
3401
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003402- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3403 the python debugger steps into a class statement: the free variables (local
3404 variables defined in an outer scope) would be deleted from the outer scope.
3405
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003406- Issue #2620: Overflow checking when allocating or reallocating memory
3407 was not always being done properly in some python types and extension
3408 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3409 all been updated to perform better checks and places in the code that
3410 would previously leak memory on the error path when such an allocation
3411 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003416- Issue #3612: Added some missing basic types in ctypes.wintypes.
3417
Benjamin Petersone977ad42008-08-20 01:42:01 +00003418- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3419 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3420
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003421- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3422 version reported by these tools does not necessarily follow the python
3423 version numbering scheme, so the module is less strict when parsing it.
3424
Nick Coghlanf70385a2008-08-18 12:42:46 +00003425- Issue #2235: Added Py3k warnings for types which will become unhashable
3426 under the stricter __hash__ inheritance rules in 3.0. Several types
3427 which did not meet the rules for hash invariants and were already
3428 unhashable in 3.0 have now been explicitly flagged as unhashable in
3429 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3430 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3431
Brett Cannon88f801d2008-08-18 00:46:22 +00003432- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3433 imported into the module but exposed as part of the module's API.
3434

3442 by using 's*' instead of 't#'.
3443
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003444- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003445 fails unicode conversion on 2nd parameter. (windows only)
3446
Facundo Batista94f243a2008-08-17 03:38:39 +00003447- Issue 2464. urllib2 now supports a malformation in the URL received
3448 in a redirect.

Facundo Batistaeb90b782008-08-16 14:44:07 +00003453- Issue #2776: fixed small issue when handling an URL with double slash
3454 after a 302 response in the case of not going through a proxy.
3455
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003456- Issue #2676: in the email package, content-type parsing was hanging on
3457 pathological input because of quadratic or exponential behaviour of a
3458 regular expression.
3459
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003460- Issue #3476: binary buffered reading through the new "io" library is now
3461 thread-safe.
3462
Brett Cannonbf3157b2008-08-14 05:00:03 +00003463- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3464 since mimetools itself is deprecated. Because modules are cached, all
3465 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3466
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003467- Issue #3134: shutil referenced undefined WindowsError symbol.
3468
Robert Schuppenies14646332008-08-10 11:01:53 +00003469- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3470 menu entries were not deleted.
3471
Brett Cannon83e81842008-08-09 23:30:55 +00003472- Copied the implementation of reduce() to _functools.reduce() to have a
3473 version that did not raise a DeprecationWarning under -3.
3474
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003475- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3476 a MemoryError rather than silently stop the iteration.
3477
Guido van Rossum59ce9012008-08-09 14:55:34 +00003478- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3479 to _sre.compile() will now be rejected. This should not affect anybody
3480 since the re.compile() function never generates invalid re-bytecode.
3481
Skip Montanaroa032bf42008-08-08 22:52:51 +00003482- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3483 upon first access it can be automatically initialized from the csv file if
3484 it wasn't initialized during instantiation.
3485
Brett Cannon3aa2a492008-08-06 22:28:09 +00003486- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3487 the reload() built-in has been removed.
3488
Brett Cannon7e30b672008-08-04 21:52:25 +00003489- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003490 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3498 raised an AttributeError.
3499
Benjamin Peterson01a24322008-07-28 23:35:27 +00003500- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003501 asking for a specific length. This problem only affected files opened
3502 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003503
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003504- Issue #3449: Update decimal module to use most recent specification
3505 (v. 1.68) and tests (v. 2.58) from IBM.
3506

3526
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003527- Issue #3394: zipfile.writestr sets external attributes when passed a
3528 file name rather than a ZipInfo instance, so files are extracted with
3529 mode 0600 rather than 000 under Unix.
3530
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003531- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3532 argument in python 2.5, this broke code that subclassed Popen to include its
3533 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3544 interaction with the tp_hash slot (added in 2.6b2) are now documented
3545
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003546- Issue #643841: The language reference now provides more detailed
3547 coverage of the lookup process for special methods. The disclaimers
3548 regarding lack of coverage of new-style classes have also been
3549 removed, since the coverage is now fairly reasonable.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003555*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003557Core and Builtins
3558-----------------
3559
Georg Brandl3e483f62008-07-16 22:57:41 +00003560- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3561 its methods now allow for items objects that can be converted to
3562 an integer using operator.index().
3563
Mark Dickinson64b7e502008-07-16 09:40:03 +00003564- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3565 produced a ValueError instead of giving the correct float.
3566
Eric Smitha5fa5a22008-07-16 00:11:49 +00003567- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3568 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3569
Mark Dickinson7103aa42008-07-15 19:08:33 +00003570- Issue #3008: the float type has a new instance method 'float.hex'
3571 and a new class method 'float.fromhex' to convert floating-point
3572 numbers to and from hexadecimal strings, respectively.
3573
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003574- Issue #2235: __hash__ is once again inherited by default. To allow
3575 collections.Hashable to remain meaningful in the presence of the
3576 default hash implementation (object.__hash__), it is now possible
3577 to explicit block inheritance of hash by setting __hash__=None at
3578 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3579 level.
3580
Nick Coghlanb028f502008-07-13 14:52:36 +00003581- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3582 the parent module cannot be found while performing an absolute import.
3583 This means that an incorrectly defined __package__ attribute will
3584 now only prevent relative imports in that module rather than causing
3585 all imports from that module to fail.
3586
Nick Coghlan14ff9942008-07-08 14:21:42 +00003587- Issue #2517: Allow unicode messages in Exceptions again by correctly
3588 bypassing the instance dictionary when looking up __unicode__ on
3589 new-style classes.
3590
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003591- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3592 set to a custom object whose write() method happens to install
3593 another file in sys.stdout.
3594
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003595- Issue #3088: Corrected a race condition in classes derived from
3596 threading.local: the first member set by a thread could be saved in
3597 another thread's dictionary.
3598
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003599- Issue #3004: Minor change to slice.indices(): the start and stop
3600 arguments are now treated identically, making the behaviour easier
3601 to describe and understand. For example, slice(None, -10,
3602 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3603 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3604 10, -1).
3605
Georg Brandl278fc502008-07-19 12:46:12 +00003606- Issue #3219: Calling a function with repeated keyword arguments,
3607 f(a=2, a=23), would not cause a syntax error. This was a regression
3608 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003609
Georg Brandl278fc502008-07-19 12:46:12 +00003610- Issue #2862: Make int and float freelist management consistent with
3611 other freelists. Changes their CompactFreeList apis into
3612 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003617- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3618 api functions without holding the GIL, which could lead to a fatal
3619 error when they failed.
3620
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003621- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00003629- Issue #3125: Remove copy_reg in multiprocessing and replace it with
3630 ForkingPickler.register() to resolve conflict with ctypes.
3631
Vinay Sajip51e65192008-07-18 09:01:10 +00003632- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00003634- Issue #3313: Fixed a crash when a failed dlopen() call does not set
3635 a valid dlerror() message.
3636
Thomas Heller2bad6572008-07-15 17:19:50 +00003637- Issue #3258: Fixed a crash when a ctypes POINTER type to an
3638 incomplete structure was created.
3639

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003646- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3647 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003648 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003649 content-length. The problem had been corrected in the 2.4 branch, but never
3650 merged into trunk.
3651

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003665- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3666 handling is now the same as that of other special attributes like __name__).
3667
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003668- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
3669 removal in Python 3.0 in favor of urllib2.urlopen().

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004056- On MacOS X it is now possible to install the framework in 64-bit
4057 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004058 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004059
4060 This is controlled by the configure argument ``--with-universal-archs``:
4061
4062 - ``--with-universal-archs=all``: install 4-way universal
4063
4064 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4065
4066 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4067
4068 This option should be used in combination with ``--enable-universalsdk=``.
4069
4070 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004120- Issue #1631171: Re-implement the 'warnings' module in C (the
4121 original Python code has been kept as backup). This will allow for
4122 using the 'warning's machinery in such places as the parser where
4123 use of pure Python code is not possible. Both the ``showarning()``
4124 and ``formatwarning()`` gain an optional 'line' argument which is
4125 not called by default for backwards-compatibility reasons. Setting
4126 ``warnings.showwarning()`` to an implementation that lacks support
4127 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Issue #2550: The approach used by client/server code for obtaining
4191 ports to listen on in network-oriented tests has been refined in an
4192 effort to facilitate running multiple instances of the entire
4193 regression test suite in parallel without issue.
4194 test_support.bind_port() has been fixed such that it will always
4195 return a unique port -- which wasn't always the case with the
4196 previous implementation, especially if socket options had been set
4197 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4198 new implementation of bind_port() will actually raise an exception
4199 if it is passed an AF_INET/SOCK_STREAM socket with either the
4200 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4201 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4202 the socket it's been passed. This currently only applies to
4203 Windows. This option prevents any other sockets from binding to the
4204 host/port we've bound to, thus removing the possibility of the
4205 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4206 when a second SOCK_STREAM socket binds and accepts to a host/port
4207 that's already been bound by another socket. The optional preferred
4208 port parameter to bind_port() has been removed. Under no
4209 circumstances should tests be hard coding ports!
4210
4211 test_support.find_unused_port() has also been introduced, which will
4212 pass a temporary socket object to bind_port() in order to obtain an
4213 unused port. The temporary socket object is then closed and
4214 deleted, and the port is returned. This method should only be used
4215 for obtaining an unused port in order to pass to an external program
4216 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4217 a parameter to a server-oriented class that doesn't give you direct
4218 access to the underlying socket used.
4219
4220 Finally, test_support.HOST has been introduced, which should be used
4221 for the host argument of any relevant socket calls (i.e. bind and
4222 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004223
4224 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004226 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4227 test_asynchat and test_socket_ssl.
4228
Georg Brandl3ee81df2008-05-17 18:14:43 +00004229 It is now possible for multiple instances of the regression test
4230 suite to run in parallel without issue.

Christian Heimes5224d282008-02-23 15:01:05 +00004505
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004506- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004507 issue 215555 for a discussion.
4508
Eric Smitha73fbe72008-02-23 03:09:44 +00004509- Added the future_builtins module, which contains hex() and oct().
4510 These are the PEP 3127 version of these functions, designed to be
4511 compatible with the hex() and oct() builtins from Python 3.0. They
4512 differ slightly in their output formats from the existing, unchanged
4513 Python 2.6 builtins. The expected usage of the future_builtins
4514 module is:
4515 from future_builtins import hex, oct
4516
Eric Smith7ef40bf2008-02-20 23:34:22 +00004517- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4518 exponents for exponents with absolute value < 100. Follows C99
4519 standard. This is a change on Windows, which would use 3 digits.
4520 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4521 so that any alterations it does to the resulting string will be
4522 available in stringlib/formatter.h (for float.__format__).
4523
Eric Smith5a3c1352008-02-19 13:21:56 +00004524- Implemented PEP 3101, Advanced String Formatting. This adds a new
4525 builtin format(); a format() method for str and unicode; a
4526 __format__() method to object, str, unicode, int, long, float, and
4527 datetime; the class string.Formatter; and the C API
4528 PyObject_Format().
4529
Georg Brandl3ee81df2008-05-17 18:14:43 +00004530- Fixed several potential crashes, all caused by specially crafted
4531 __del__ methods exploiting objects in temporarily inconsistent
4532 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004533
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004534- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004535 prevent a possible crash: an Abstract Base Class would try to access
4536 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004537
Georg Brandl3ee81df2008-05-17 18:14:43 +00004538- Fixed repr() and str() of complex numbers with infinity or nan as
4539 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004540
Georg Brandl3ee81df2008-05-17 18:14:43 +00004541- Clear all free lists during a gc.collect() of the highest generation
4542 in order to allow pymalloc to free more arenas. Python may give back
4543 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004544
Georg Brandl3ee81df2008-05-17 18:14:43 +00004545- Issue #2045: Fix an infinite recursion triggered when printing a
4546 subclass of collections.defaultdict, if its default_factory is set
4547 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004548
Christian Heimesf75dbef2008-02-08 00:11:31 +00004549- Fixed a minor memory leak in dictobject.c. The content of the free
4550 list was not freed on interpreter shutdown.
4551
Georg Brandl21e99f42010-03-07 15:23:59 +00004552- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004553 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004554
Georg Brandl3ee81df2008-05-17 18:14:43 +00004555- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4556 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004557 to compact the internal free lists of pre-allocted ints and floats.
4558
Georg Brandl3ee81df2008-05-17 18:14:43 +00004559- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4560 calls. Python expected the return type int but the fork familie
4561 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004562
Georg Brandl3ee81df2008-05-17 18:14:43 +00004563- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4564 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004565
Georg Brandl3ee81df2008-05-17 18:14:43 +00004566- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4567 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004568
Georg Brandl3ee81df2008-05-17 18:14:43 +00004569- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4570 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004571
Georg Brandl3ee81df2008-05-17 18:14:43 +00004572- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4573 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004574
Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Patch #1473257: generator objects gain a gi_code attribute. This is
4576 the same object as the func_code attribute of the function that
4577 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004578
Georg Brandl3ee81df2008-05-17 18:14:43 +00004579- Issue #1920: "while 0" statements were completely removed by the
4580 compiler, even in the presence of an "else" clause, which is
4581 supposed to be run when the condition is false. Now the compiler
4582 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004583
Guido van Rossumeead05f2008-01-24 18:21:02 +00004584- A few crashers fixed: weakref_in_del.py (issue #1377858);
4585 loosing_dict_ref.py (issue #1303614, test67.py);
4586 borrowed_ref_[34].py (not in tracker).
4587
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004588- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004589 suppressed while an extension is loaded by calling SetErrorMode in
4590 dynload_win.c. The error is still reported properly.
4591
Georg Brandl3ee81df2008-05-17 18:14:43 +00004592- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004593 several extension methods and modules do not work without unicode
4594 support.
4595
Georg Brandl26543b12008-01-21 18:36:51 +00004596- Issue #1882: when compiling code from a string, encoding cookies in the
4597 second line of code were not always recognized correctly.
4598
Georg Brandl14404b62008-01-19 19:27:05 +00004599- Issue #1679: "0x" was taken as a valid integer literal.
4600
Georg Brandl6caad7d2008-01-26 14:19:22 +00004601- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004602 added.
4603
Christian Heimesc94e2b52008-01-14 04:13:37 +00004604- sys.float_info / PyFloat_GetInfo: The floating point information
4605 object was converted from a dict to a specialized structseq object.
4606
Georg Brandl3ee81df2008-05-17 18:14:43 +00004607- Patch #1816: Added sys.flags structseq. It exposes the status of
4608 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004609
Georg Brandl3ee81df2008-05-17 18:14:43 +00004610- Objects/structseq.c: Implemented new structseq representation. The
4611 patch makes structseqs (e.g. the return value of os.stat) more
4612 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004613
Georg Brandl3ee81df2008-05-17 18:14:43 +00004614- Patch #1700288: added a type attribute cache that caches method
4615 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004616
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004617- Bug #1776: __import__() no longer accepts filenames on any platform.

4621
Georg Brandl3ee81df2008-05-17 18:14:43 +00004622- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4623 envvar and sys.dont_write_bytecode attribute. All these can be set
4624 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004625
Georg Brandl3ee81df2008-05-17 18:14:43 +00004626- Improve some exception messages when Windows fails to load an
4627 extension module. Now we get for example '%1 is not a valid Win32
4628 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004629
Georg Brandl3ee81df2008-05-17 18:14:43 +00004630- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004632- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4633 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004634
Christian Heimes0a8143f2007-12-18 23:22:54 +00004635- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004636 and INF. float("nan"), float("inf") and float("-inf") now work on
4637 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004638
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639- Compiler now generates simpler and faster code for dictionary
4640 literals. The oparg for BUILD_MAP now indicates an estimated
4641 dictionary size. There is a new opcode, STORE_MAP, for adding
4642 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004643
Georg Brandl3ee81df2008-05-17 18:14:43 +00004644- Issue #1638: %zd configure test fails on Linux.

4657 __package__ attribute.
4658
Georg Brandl3ee81df2008-05-17 18:14:43 +00004659- Issue #1402: Fix a crash on exit, when another thread is still
4660 running, and if the deallocation of its frames somehow calls the
4661 PyGILState_Ensure() / PyGILState_Release() functions.

4672 file can now be directly executed by passing their name to the
4673 interpreter. The directory/zipfile is automatically inserted as the
4674 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004675
Georg Brandl3ee81df2008-05-17 18:14:43 +00004676- Issue #1265: Fix a problem with sys.settrace, if the tracing
4677 function uses a generator expression when at the same time the
4678 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004679
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004680- sets and frozensets now have an isdisjoint() method.
4681
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004682- optimize the performance of builtin.sum().

4685
Georg Brandl21e99f42010-03-07 15:23:59 +00004686- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004687 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4688 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004689
Georg Brandl3ee81df2008-05-17 18:14:43 +00004690- Issue #1686386: Tuple's tp_repr did not take into account the
4691 possibility of having a self-referential tuple, which is possible
4692 from C code. Nor did object's tp_str consider that a type's tp_str
4693 could do something that could lead to an inifinite recursion.
4694 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4695 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004696
Georg Brandl3ee81df2008-05-17 18:14:43 +00004697- Issue #1164: It was possible to trigger deadlock when using the
4698 'print' statement to write to a file since the GIL was not released
4699 as needed. Now PyObject_Print() does the right thing along with
4700 various tp_print implementations of the built-in types and those in
4701 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004702
Georg Brandl3ee81df2008-05-17 18:14:43 +00004703- Issue #1147: Exceptions were directly allowing string exceptions in
4704 their throw() method even though string exceptions no longer
4705 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004706

Brett Cannon1e534b52007-09-07 04:18:30 +00004710- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004711 PyObject_Call() never calling back out to Python code to trigger
4712 recursion depth updates/checks. Required the creation of a static
4713 RuntimeError instance in case normalizing an exception put the
4714 recursion check value past its limit. Fixes crashers
4715 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004716

Georg Brandl3ee81df2008-05-17 18:14:43 +00004731 __*__ attributes. (Some already existed, e.g., __doc__ and
4732 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004733
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004734- Add -3 option to the interpreter to warn about features that are
4735 deprecated and will be changed/removed in Python 3.0.
4736
Georg Brandl2134e752007-05-21 20:34:16 +00004737- Patch #1686487: you can now pass any mapping after '**' in function
4738 calls.
4739
Collin Winter62903052007-05-18 23:11:24 +00004740- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004741 "except E as target:". This is to provide forwards compatibility
4742 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004749- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004750 setting a plain string, ie don't expand to single letter identifiers.

4756 remaining characters.
4757
Georg Brandl5cb76c12007-03-21 09:00:39 +00004758- Patch #1682205: a TypeError while unpacking an iterable is no longer

Guido van Rossum143b5642007-03-23 04:58:42 +00004763- Bug #1683368: The object.__init__() and object.__new__() methods are
4764 now stricter in rejecting excess arguments. The only time when
4765 either allows excess arguments is when it is not overridden and the
4766 other one is. For backwards compatibility, when both are
4767 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004768 warning later). Also, type.__init__() insists on the same signature
4769 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004771- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4772 object to complex using its __complex__() method before falling back
4773 to the __float__() method. Therefore, the functions in the cmath
4774 module now can operate on objects that define a __complex__()
4775 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00004793- Bug #1678647: write a newline after printing an exception in any
4794 case, even when converting the value to a string failed.
4795
Georg Brandl871f1bc2007-03-12 13:17:36 +00004796- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004797 its argument, if it exists. If not, it will work like before. This
4798 allows customizing the output of dir() in the presence of a
4799 __getattr__().

4809 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00004811- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004812 makes the filenames the warning module prints much more sensible
4813 when a PYTHONSTARTUP file is used.

4827 sq_ass_slice instead of the sq_slice slot.
4828
Georg Brandl3ee81df2008-05-17 18:14:43 +00004829- When printing an unraisable error, don't print exceptions. before

4882 embedded in the string to convert.
4883
Georg Brandl846f73a2006-10-08 07:11:54 +00004884- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004932 generator expressions (x for x, in ... ) works again. Fixing this
4933 problem required changing the .pyc magic number. This means that
4934 .pyc files generated before 2.5c2 will be regenerated.

5456 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00005741- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5742 with RFC 3207 and forgets any knowledge obtained from the server not
5743 obtained from the TLS negotiation itself. Patch contributed by Bill
5744 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005745
Georg Brandl3ee81df2008-05-17 18:14:43 +00005746- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005747 that the SMTP.starttls() caller no longer needs to call ehlo()
5748 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005749 does not claim to support starttls. Adds the
5750 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5751 Fenner.

5831 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5832 silently miscode subclasses of those types. Now, it raises a
5833 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005834

Georg Brandl3ee81df2008-05-17 18:14:43 +00005849 time so that opening a database previously created with the DB_DUP
5850 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5851 opens. Specifically: dictionary assignment to a DB object will
5852 replace all values for a given key when the database allows
5853 duplicate values. DB users should use DB.put(k, v) when they want
5854 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005855

5861 characters with ASCII value less than 32. Also, it correctly quotes
5862 dots only if they occur on a single line, as opposed to the previous
5863 behavior of quoting dots if they are the second character of any
5864 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005865
