Benjamin Petersone3c10452010-07-03 14:51:25 +00007What's New in Python 2.7.1?
8===========================

11
12Core and Builtins
13-----------------
14
Antoine Pitrou0a7b65b2010-09-08 12:40:49 +000015- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
16 thread-local storage key.
17
Victor Stinnercaafd772010-09-08 10:51:01 +000018- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
19 encoding and errors attributes instead of using utf-8 in strict mode, to get
20 the same behaviour than the print statement.
21
Antoine Pitrou9cf85f12010-09-01 21:17:34 +000022- Issue #9737: Fix a crash when trying to delete a slice or an item from
23 a memoryview object.
24
Martin v. Löwis6086b0d2010-08-19 09:09:04 +000025- Restore GIL in nis_cat in case of error.
26
Benjamin Peterson6f3d6a92010-08-25 23:17:42 +000027- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
28
Florent Xicluna172e15f2010-08-09 20:02:00 +000029- Issue #8530: Prevent stringlib fastsearch from reading beyond the front
30 of an array.
31
Raymond Hettinger3ad323e2010-08-06 10:18:56 +000032- Issue #83755: Implicit set-to-frozenset conversion was not thread-safe.
33
Mark Dickinsonaad57bd2010-08-01 10:45:15 +000034- Issue #9416: Fix some issues with complex formatting where the
35 output with no type specifier failed to match the str output:
36
37 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
38 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
39
Antoine Pitrou32669782010-07-11 12:14:05 +000040- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
41 compiler.

45
Antoine Pitroue4195e82010-09-12 14:56:27 +000046- Issue #9837: The read() method of ZipExtFile objects (as returned by
47 ZipFile.open()) could return more bytes than requested.
48
Raymond Hettinger20397532010-09-12 02:11:45 +000049- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
50 This prevents user-created self-referencing ordered dictionaries from
51 becoming permanently uncollectable GC garbage. The downside is that
52 removing __del__ means that the internal doubly-linked list has to wait for
53 GC collection rather than freeing memory immediately when the refcnt drops
54 to zero.
55
Raymond Hettingerffd2a422010-09-10 10:47:22 +000056- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
57 different internal state for small values of n. Fixed by salting the
58 value.
59
Antoine Pitrouc818ed42010-09-07 21:40:25 +000060- Issue #9792: In case of connection failure, socket.create_connection()
61 would swallow the exception and raise a new one, making it impossible
62 to fetch the original errno, or to filter timeout errors. Now the
63 original error is re-raised.
64
Antoine Pitrouf4f61712010-09-07 16:34:47 +000065- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
66 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
67 be updated back after the system call. Original patch by Brian Brazil.
68
Antoine Pitroudca9de92010-09-04 17:52:26 +000069- Issue #1100562: Fix deep-copying of objects derived from the list and
70 dict types. Patch by Michele Orrù and Björn Lindqvist.
71
Fred Drakea1e627d2010-09-03 03:55:50 +000072- Issue #7005: Fixed output of None values for RawConfigParser.write and
73 ConfigParser.write.
74
Daniel Stutzbach66c981b2010-08-31 20:29:39 +000075- Issue #808164: Fixed socket.close to avoid references to globals, to
76 avoid issues when socket.close is called from a __del__ method.
77
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +000078- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
79 falling into recursion.
80
R. David Murray7c4bf552010-08-25 01:45:57 +000081- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
82 character years even if the message contains RFC822 two character years.
83
Daniel Stutzbach91287322010-08-24 21:09:30 +000084- Issue #8750: Fixed MutableSet's methods to correctly handle
85 reflexive operations, namely x -= x and x ^= x.
86
Victor Stinnercaafd772010-09-08 10:51:01 +000087- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +000088 error handling when accepting a new connection.
89
Giampaolo Rodolà63308d72010-08-23 21:58:47 +000090- Issue #658749: asyncore's connect() method now correctly interprets winsock
91 errors.
92
Vinay Sajip1ddd51f2010-08-23 17:50:30 +000093- Issue #9501: Fixed logging regressions in cleanup code.
94

96 module now correctly return a set. (Patch by Eli Bendersky.)
97

99 ignored by the buffered IO layer anymore.
100
Benjamin Peterson52c36052010-08-21 03:03:22 +0000101- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
102 are not held onto after they are deleted elsewhere.
103
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000104- Issue #9626: the view methods for collections.OrderedDict() were returning
105 the unordered versions inherited from dict. Those methods are now
106 overridden to provide ordered views.
107
Éric Araujo0389ae62010-08-14 03:07:46 +0000108- Issue #8688: MANIFEST files created by distutils now include a magic
109 comment indicating they are generated. Manually maintained MANIFESTs
110 without this marker will not be overwritten or removed.
111
Antoine Pitroue1436d12010-08-12 15:25:51 +0000112- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
113 and a BadZipfile error is raised if it doesn't match (as used to be the
114 case in Python 2.5 and earlier).
115
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000116- Issue #9550: a BufferedReader could issue an additional read when the
117 original read request had been satisfied, which could block indefinitely
118 when the underlying raw IO channel was e.g. a socket. Report and original
119 patch by Jason V. Miller.
120
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000121- Issue #9551: Don't raise TypeError when setting the value to None for

125 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
126
Antoine Pitrou99009162010-08-09 22:51:24 +0000127- Issue #3757: thread-local objects now support cyclic garbage collection.
128 Thread-local objects involved in reference cycles will be deallocated
129 timely by the cyclic GC, even if the underlying thread is still running.
130
Florent Xicluna2f1b1ff2010-08-09 20:46:49 +0000131- Issue #6231: Fix xml.etree.ElementInclude to include the tail of the

464 start byte and the continuation byte(s) are now considered invalid, instead
465 of the number of bytes specified by the start byte.
466 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
467 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
468 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

479 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

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

Georg Brandlfee0f442010-05-22 21:26:21 +0000864- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
865 with a non-empty format string. This is an effort to future-proof user
866 code. If a derived class does not currently implement __format__ but later
867 adds its own __format__, it would most likely break user code that had
868 supplied a format string. This will be changed to a DeprecationWaring in
869 Python 3.3 and it will be an error in Python 3.4.

1340 XML processing instructions and comments. These raw characters are allowed
1341 by the XML specification, and are necessary when outputting e.g. PHP code in
1342 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +00001350- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001351 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001352 Also, raise ValueError rather than TypeError when an unknown TIPC address
1353 type is specified. Patch by Brian Curtin.
1354
Vinay Sajip28c382f2010-02-04 18:48:53 +00001355- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001357- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001358 file position when calling `truncate()`. It would previously change the file
1359 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001360 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1361
Georg Brandlba83f822010-03-14 09:50:54 +00001362- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1363 class used to represent files stored inside an archive. The new
1364 implementation is significantly faster and can be wrapped in a
1365 ``io.BufferedReader`` object for more speedups. It also solves an issue
1366 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1367 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00001376
Georg Brandlba83f822010-03-14 09:50:54 +00001377- Issue #7748: Since unicode values are supported for some metadata options in
1378 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1379 encoded string for them. This ensures that the upload and register commands
1380 send the correct values to PyPI without any error.

1455-----------------
1456
Georg Brandlba83f822010-03-14 09:50:54 +00001457- The ``__complex__()`` method is now looked up on the class of instances to
1458 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001460- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1461 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1462
Mark Dickinson1b34d252010-01-01 17:27:30 +00001463- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001464 DeprecationWarning when passed a float argument where an integer was expected.
1465 These functions and methods now raise TypeError instead. The majority of the
1466 effects of this change are in the extension modules, but some core functions
1467 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1468 and many unicode/str methods.

1479 used to drop the time part of the result.
1480
Georg Brandlba83f822010-03-14 09:50:54 +00001481- Issue #1811: Improve accuracy and cross-platform consistency for true division
1482 of integers: the result of a/b is now correctly rounded for ints a and b (at
1483 least on IEEE 754 platforms), and in particular does not depend on the
1484 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001485
Georg Brandlba83f822010-03-14 09:50:54 +00001486- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1487 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1488 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001491 executables on OSX.
1492
Georg Brandlba83f822010-03-14 09:50:54 +00001493 These executables now work properly with the arch(1) command: ``arch -ppc
1494 python`` will start a universal binary version of python in PPC mode (unlike
1495 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001496
Georg Brandlba83f822010-03-14 09:50:54 +00001497- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

Georg Brandlba83f822010-03-14 09:50:54 +00001518 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00001651- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1652 decimal string that's guaranteed to round back to x under correct rounding
1653 (with round-half-to-even rounding mode). Previously it gave a string based on
1654 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1655 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1656 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001657
Georg Brandlba83f822010-03-14 09:50:54 +00001658- Issue #7117: On almost all platforms: float-to-string and string-to-float
1659 conversions within Python are now correctly rounded. Places these conversions
1660 occur include: str for floats and complex numbers; the float and complex
1661 constructors; old-style and new-style numeric formatting; serialization and
1662 deserialization of floats and complex numbers using marshal, pickle and json;
1663 parsing of float and imaginary literals in Python code; Decimal-to-float
1664 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001665
Georg Brandlba83f822010-03-14 09:50:54 +00001666 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1667 providing correctly-rounded strtod and dtoa C functions. This code is
1668 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1669 the C compiler. There may be a small number of platforms on which correct
1670 operation of this code cannot be guaranteed, so the code is not used: notably,
1671 this applies to platforms where the C double format is not IEEE 754 binary64,
1672 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1673 and Python's configure script is unable to determine how to change the FPU
1674 precision. On these platforms conversions use the platform strtod and dtoa,
1675 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001677- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1678 uses the correctly-rounded string <-> float conversions described above (when
1679 available), and so produces correctly rounded results that will display nicely
1680 under the float repr. There are two related small changes: (1) round now
1681 accepts any class with an ``__index__()`` method for its second argument (but
1682 no longer accepts floats for the second argument), and (2) an excessively
1683 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1684 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001826
Georg Brandlba83f822010-03-14 09:50:54 +00001827 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1828 (2) parsing of strings representing infinities and nans was locale aware; and
1829 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001831- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1832 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1833 but with at least one decimal point and with a default precision
1834 of 12. Previously, the behavior the same but with a default precision of 6.
1835 This more closely matches ``str()``, and reduces surprises when adding
1836 alignment flags to the empty presentation type. This also affects the new
1837 complex.__format__ in the same way.
1838
1839- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

1911 internal representation of integers, for performance reasons. Base 2**30 is
1912 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00002035- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2036 file objects with closefd=False. The file descriptor is still kept open but
2037 the file object behaves like a closed file. The ``FileIO`` object also got a
2038 new readonly attribute ``closefd``.

2090 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

3266 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3267 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3268 neither __int__ nor __long__, TypeError used to be raised (with a
3269 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3270 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00003323 leak-chasing test runs give sensible results. The previous method of reaping
3324 threads could return successfully while some Thread objects were still

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003465- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3466
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003467- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3468 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3469 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3470 ``printf`` function, whereas PyString_FromFormat has an independent
3471 implementation and uses "%zd" on all platforms for size_t values.
3472 This makes a difference on win64, where ``printf`` needs "%Id" to display
3473 64bit values.
3474
Benjamin Peterson97179b02008-09-09 20:55:01 +00003475- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3476 error.
3477
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003478- Issue #3777: long() applied to a float object now always return a long
3479 object; previously an int would be returned for small values. the __long__
3480 method is allowed to return either an int or a long, but the behaviour of
3481 float objects should not change to respect backward compatibility.
3482
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003483- Issue #3751: str.rpartition would perform a left-partition when called with
3484 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003489 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003490 was correctly parsed but parsing of subsequent arguments failed.
3491
Vinay Sajip35e3b032008-09-01 14:33:59 +00003492- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003493 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3494 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3495 when given a tuple of classes as second argument, were looking up
3496 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3497 type object.
3498
Neal Norwitz18aa3882008-08-24 05:04:52 +00003499- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003568 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3569 for catch_warnings() also led to an improvement in the raising of a

3642-----------------
3643
Guido van Rossumf8402962008-08-20 15:01:50 +00003644- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3645 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3646 extensions do not automatically benefit from the class attribute
3647 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3648 to their tp_flags field if they care. This is a backwards
3649 compatibility feature; in 3.0, all types will use the cache by
3650 default.
3651
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003652- Keyword arguments can now follow starred arguments. (``f(a, *args,
3653 keyword=23)`` is now valid syntax.)
3654
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003655- ctypes function pointers that are COM methods have a boolean True
3656 value again.
3657
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003658- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3659 by denying s# to parse objects that have a releasebuffer procedure,
3660 and introducing s*.
3661
Georg Brandl1e13ea92008-08-11 09:07:59 +00003662- Issue #3537: Fix an assertion failure when an empty but presized dict
3663 object was stored in the freelist.
3664
Mark Dickinsonb6467572008-08-04 21:30:09 +00003665- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3666 ValueError consistently across platforms.
3667
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003668- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3669 (64bit Unix, for example), unichr() would truncate its argument and return
3670 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3671
Neal Norwitze7d8be82008-07-31 17:17:14 +00003672- Apply security patches from Apple.
3673
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003674- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3675 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3676
Antoine Pitrou92f82162008-07-25 22:22:08 +00003677- Issue #1819: function calls with several named parameters are now on
3678 average 35% faster (as measured by pybench).
3679
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003680- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3681 the python debugger steps into a class statement: the free variables (local
3682 variables defined in an outer scope) would be deleted from the outer scope.
3683
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003684- Issue #2620: Overflow checking when allocating or reallocating memory
3685 was not always being done properly in some python types and extension
3686 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3687 all been updated to perform better checks and places in the code that
3688 would previously leak memory on the error path when such an allocation
3689 failed have been fixed.

3695
Benjamin Petersone977ad42008-08-20 01:42:01 +00003696- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3697 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3698
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003699- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3700 version reported by these tools does not necessarily follow the python
3701 version numbering scheme, so the module is less strict when parsing it.
3702
Nick Coghlanf70385a2008-08-18 12:42:46 +00003703- Issue #2235: Added Py3k warnings for types which will become unhashable
3704 under the stricter __hash__ inheritance rules in 3.0. Several types
3705 which did not meet the rules for hash invariants and were already

Antoine Pitroude781a42008-08-09 12:43:23 +00003779 asking for a specific length. This problem only affected files opened

3822 interaction with the tp_hash slot (added in 2.6b2) are now documented
3823
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003824- Issue #643841: The language reference now provides more detailed

3831================================
3832
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003833*Release date: 17-Jul-2008*
3834
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003835Core and Builtins
3836-----------------
3837
Georg Brandl3e483f62008-07-16 22:57:41 +00003838- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3839 its methods now allow for items objects that can be converted to
3840 an integer using operator.index().
3841
Mark Dickinson64b7e502008-07-16 09:40:03 +00003842- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3843 produced a ValueError instead of giving the correct float.
3844
Eric Smitha5fa5a22008-07-16 00:11:49 +00003845- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3846 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3847
Mark Dickinson7103aa42008-07-15 19:08:33 +00003848- Issue #3008: the float type has a new instance method 'float.hex'
3849 and a new class method 'float.fromhex' to convert floating-point
3850 numbers to and from hexadecimal strings, respectively.
3851
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003852- Issue #2235: __hash__ is once again inherited by default. To allow
3853 collections.Hashable to remain meaningful in the presence of the
3854 default hash implementation (object.__hash__), it is now possible
3855 to explicit block inheritance of hash by setting __hash__=None at
3856 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3857 level.
3858
Nick Coghlanb028f502008-07-13 14:52:36 +00003859- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3860 the parent module cannot be found while performing an absolute import.
3861 This means that an incorrectly defined __package__ attribute will
3862 now only prevent relative imports in that module rather than causing
3863 all imports from that module to fail.
3864
Nick Coghlan14ff9942008-07-08 14:21:42 +00003865- Issue #2517: Allow unicode messages in Exceptions again by correctly
3866 bypassing the instance dictionary when looking up __unicode__ on
3867 new-style classes.
3868
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003869- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3870 set to a custom object whose write() method happens to install
3871 another file in sys.stdout.
3872
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003873- Issue #3088: Corrected a race condition in classes derived from
3874 threading.local: the first member set by a thread could be saved in
3875 another thread's dictionary.
3876
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003877- Issue #3004: Minor change to slice.indices(): the start and stop
3878 arguments are now treated identically, making the behaviour easier
3879 to describe and understand. For example, slice(None, -10,
3880 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3881 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3882 10, -1).
3883
Georg Brandl278fc502008-07-19 12:46:12 +00003884- Issue #3219: Calling a function with repeated keyword arguments,
3885 f(a=2, a=23), would not cause a syntax error. This was a regression
3886 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003887
Georg Brandl278fc502008-07-19 12:46:12 +00003888- Issue #2862: Make int and float freelist management consistent with
3889 other freelists. Changes their CompactFreeList apis into
3890 ClearFreeList apis and calls them via gc.collect().

3896 api functions without holding the GIL, which could lead to a fatal
3897 error when they failed.
3898
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003899- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003924- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3925 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003926 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003927 content-length. The problem had been corrected in the 2.4 branch, but never
3928 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003943- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4335 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004336 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004337
4338 This is controlled by the configure argument ``--with-universal-archs``:
4339
4340 - ``--with-universal-archs=all``: install 4-way universal
4341
4342 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4343
4344 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4345
4346 This option should be used in combination with ``--enable-universalsdk=``.
4347
4348 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 +00004398- Issue #1631171: Re-implement the 'warnings' module in C (the
4399 original Python code has been kept as backup). This will allow for
4400 using the 'warning's machinery in such places as the parser where
4401 use of pure Python code is not possible. Both the ``showarning()``
4402 and ``formatwarning()`` gain an optional 'line' argument which is
4403 not called by default for backwards-compatibility reasons. Setting
4404 ``warnings.showwarning()`` to an implementation that lacks support
4405 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004468- Issue #2550: The approach used by client/server code for obtaining
4469 ports to listen on in network-oriented tests has been refined in an
4470 effort to facilitate running multiple instances of the entire
4471 regression test suite in parallel without issue.
4472 test_support.bind_port() has been fixed such that it will always
4473 return a unique port -- which wasn't always the case with the
4474 previous implementation, especially if socket options had been set
4475 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4476 new implementation of bind_port() will actually raise an exception
4477 if it is passed an AF_INET/SOCK_STREAM socket with either the
4478 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4479 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4480 the socket it's been passed. This currently only applies to
4481 Windows. This option prevents any other sockets from binding to the
4482 host/port we've bound to, thus removing the possibility of the
4483 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4484 when a second SOCK_STREAM socket binds and accepts to a host/port
4485 that's already been bound by another socket. The optional preferred
4486 port parameter to bind_port() has been removed. Under no
4487 circumstances should tests be hard coding ports!
4488
4489 test_support.find_unused_port() has also been introduced, which will
4490 pass a temporary socket object to bind_port() in order to obtain an
4491 unused port. The temporary socket object is then closed and
4492 deleted, and the port is returned. This method should only be used
4493 for obtaining an unused port in order to pass to an external program
4494 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4495 a parameter to a server-oriented class that doesn't give you direct
4496 access to the underlying socket used.
4497
4498 Finally, test_support.HOST has been introduced, which should be used
4499 for the host argument of any relevant socket calls (i.e. bind and
4500 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004501
4502 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004503 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004504 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4505 test_asynchat and test_socket_ssl.
4506
Georg Brandl3ee81df2008-05-17 18:14:43 +00004507 It is now possible for multiple instances of the regression test
4508 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00004562- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00004563 \Uxxxxxxxx did not accept values outside the Basic Multilingual
4564 Plane. This affected raw unicode literals and the
4565 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
4566 this case, like normal unicode literals and the 'unicode-escape'
4567 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00004787- Added the future_builtins module, which contains hex() and oct().
4788 These are the PEP 3127 version of these functions, designed to be
4789 compatible with the hex() and oct() builtins from Python 3.0. They
4790 differ slightly in their output formats from the existing, unchanged
4791 Python 2.6 builtins. The expected usage of the future_builtins
4792 module is:

4794
Eric Smith7ef40bf2008-02-20 23:34:22 +00004795- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4796 exponents for exponents with absolute value < 100. Follows C99
4797 standard. This is a change on Windows, which would use 3 digits.
4798 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4799 so that any alterations it does to the resulting string will be
4800 available in stringlib/formatter.h (for float.__format__).
4801
Eric Smith5a3c1352008-02-19 13:21:56 +00004802- Implemented PEP 3101, Advanced String Formatting. This adds a new
4803 builtin format(); a format() method for str and unicode; a
4804 __format__() method to object, str, unicode, int, long, float, and
4805 datetime; the class string.Formatter; and the C API
4806 PyObject_Format().
4807
Georg Brandl3ee81df2008-05-17 18:14:43 +00004808- Fixed several potential crashes, all caused by specially crafted
4809 __del__ methods exploiting objects in temporarily inconsistent
4810 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004811
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004812- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004813 prevent a possible crash: an Abstract Base Class would try to access
4814 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004815

Georg Brandl3ee81df2008-05-17 18:14:43 +00004819- Clear all free lists during a gc.collect() of the highest generation
4820 in order to allow pymalloc to free more arenas. Python may give back
4821 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004822
Georg Brandl3ee81df2008-05-17 18:14:43 +00004823- Issue #2045: Fix an infinite recursion triggered when printing a
4824 subclass of collections.defaultdict, if its default_factory is set
4825 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00004827- Fixed a minor memory leak in dictobject.c. The content of the free
4828 list was not freed on interpreter shutdown.
4829
Georg Brandl21e99f42010-03-07 15:23:59 +00004830- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004831 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004832

Georg Brandl3ee81df2008-05-17 18:14:43 +00004853- Patch #1473257: generator objects gain a gi_code attribute. This is
4854 the same object as the func_code attribute of the function that
4855 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004856
Georg Brandl3ee81df2008-05-17 18:14:43 +00004857- Issue #1920: "while 0" statements were completely removed by the
4858 compiler, even in the presence of an "else" clause, which is
4859 supposed to be run when the condition is false. Now the compiler
4860 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004861
Guido van Rossumeead05f2008-01-24 18:21:02 +00004862- A few crashers fixed: weakref_in_del.py (issue #1377858);
4863 loosing_dict_ref.py (issue #1303614, test67.py);
4864 borrowed_ref_[34].py (not in tracker).
4865
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004866- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004867 suppressed while an extension is loaded by calling SetErrorMode in
4868 dynload_win.c. The error is still reported properly.
4869
Georg Brandl3ee81df2008-05-17 18:14:43 +00004870- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004871 several extension methods and modules do not work without unicode
4872 support.
4873
Georg Brandl26543b12008-01-21 18:36:51 +00004874- Issue #1882: when compiling code from a string, encoding cookies in the

4878
Georg Brandl6caad7d2008-01-26 14:19:22 +00004879- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004880 added.
4881
Christian Heimesc94e2b52008-01-14 04:13:37 +00004882- sys.float_info / PyFloat_GetInfo: The floating point information
4883 object was converted from a dict to a specialized structseq object.
4884
Georg Brandl3ee81df2008-05-17 18:14:43 +00004885- Patch #1816: Added sys.flags structseq. It exposes the status of
4886 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004887
Georg Brandl3ee81df2008-05-17 18:14:43 +00004888- Objects/structseq.c: Implemented new structseq representation. The
4889 patch makes structseqs (e.g. the return value of os.stat) more
4890 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004891
Georg Brandl3ee81df2008-05-17 18:14:43 +00004892- Patch #1700288: added a type attribute cache that caches method
4893 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004894
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004895- Bug #1776: __import__() no longer accepts filenames on any platform.

4901 envvar and sys.dont_write_bytecode attribute. All these can be set
4902 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004903
Georg Brandl3ee81df2008-05-17 18:14:43 +00004904- Improve some exception messages when Windows fails to load an
4905 extension module. Now we get for example '%1 is not a valid Win32
4906 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00004913- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004914 and INF. float("nan"), float("inf") and float("-inf") now work on
4915 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004916
Georg Brandl3ee81df2008-05-17 18:14:43 +00004917- Compiler now generates simpler and faster code for dictionary

4963
Georg Brandl21e99f42010-03-07 15:23:59 +00004964- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004965 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4966 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004967
Georg Brandl3ee81df2008-05-17 18:14:43 +00004968- Issue #1686386: Tuple's tp_repr did not take into account the
4969 possibility of having a self-referential tuple, which is possible
4970 from C code. Nor did object's tp_str consider that a type's tp_str
4971 could do something that could lead to an inifinite recursion.
4972 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4973 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004974
Georg Brandl3ee81df2008-05-17 18:14:43 +00004975- Issue #1164: It was possible to trigger deadlock when using the
4976 'print' statement to write to a file since the GIL was not released
4977 as needed. Now PyObject_Print() does the right thing along with
4978 various tp_print implementations of the built-in types and those in
4979 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004980
Georg Brandl3ee81df2008-05-17 18:14:43 +00004981- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00004989 PyObject_Call() never calling back out to Python code to trigger
4990 recursion depth updates/checks. Required the creation of a static
4991 RuntimeError instance in case normalizing an exception put the
4992 recursion check value past its limit. Fixes crashers

5016 calls.
5017
Collin Winter62903052007-05-18 23:11:24 +00005018- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005019 "except E as target:". This is to provide forwards compatibility
5020 with Python 3.0.

Georg Brandl5cb76c12007-03-21 09:00:39 +00005036- Patch #1682205: a TypeError while unpacking an iterable is no longer

Guido van Rossum143b5642007-03-23 04:58:42 +00005041- Bug #1683368: The object.__init__() and object.__new__() methods are
5042 now stricter in rejecting excess arguments. The only time when
5043 either allows excess arguments is when it is not overridden and the
5044 other one is. For backwards compatibility, when both are
5045 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005046 warning later). Also, type.__init__() insists on the same signature
5047 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005049- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5050 object to complex using its __complex__() method before falling back
5051 to the __float__() method. Therefore, the functions in the cmath
5052 module now can operate on objects that define a __complex__()
5053 method.

5073
Georg Brandl871f1bc2007-03-12 13:17:36 +00005074- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005075 its argument, if it exists. If not, it will work like before. This
5076 allows customizing the output of dir() in the presence of a

Georg Brandlaa2321b2007-03-07 00:40:28 +00005089- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005090 makes the filenames the warning module prints much more sensible
5091 when a PYTHONSTARTUP file is used.

5106
Georg Brandl3ee81df2008-05-17 18:14:43 +00005107- When printing an unraisable error, don't print exceptions. before

5160 embedded in the string to convert.
5161
Georg Brandl846f73a2006-10-08 07:11:54 +00005162- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00005210 generator expressions (x for x, in ... ) works again. Fixing this
5211 problem required changing the .pyc magic number. This means that
5212 .pyc files generated before 2.5c2 will be regenerated.

6013 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00006014
Georg Brandl3ee81df2008-05-17 18:14:43 +00006015- The implementation of UnicodeError objects has been simplified
6016 (start and end attributes are now stored directly as Py_ssize_t
6017 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006019- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6020 with RFC 3207 and forgets any knowledge obtained from the server not
6021 obtained from the TLS negotiation itself. Patch contributed by Bill
6022 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006023
Georg Brandl3ee81df2008-05-17 18:14:43 +00006024- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006025 that the SMTP.starttls() caller no longer needs to call ehlo()
6026 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006027 does not claim to support starttls. Adds the
6028 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6029 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006071- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00006072 works as expected. ``mmap.find`` also takes an optional ``end``
6073 parameter.

6098 contents before adding elements from the iterable. This fix brings
6099 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00006100
Georg Brandl3ee81df2008-05-17 18:14:43 +00006101- Added wide char functions to msvcrt module: getwch, getwche, putwch

6107
Georg Brandl3ee81df2008-05-17 18:14:43 +00006108- Marshal.dumps() now expects exact type matches for int, long, float,
6109 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6110 silently miscode subclasses of those types. Now, it raises a
6111 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006112

Georg Brandl3ee81df2008-05-17 18:14:43 +00006127 time so that opening a database previously created with the DB_DUP
6128 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6129 opens. Specifically: dictionary assignment to a DB object will
6130 replace all values for a given key when the database allows
6131 duplicate values. DB users should use DB.put(k, v) when they want
6132 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006133

6139 characters with ASCII value less than 32. Also, it correctly quotes
6140 dots only if they occur on a single line, as opposed to the previous
6141 behavior of quoting dots if they are the second character of any
6142 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006143

Georg Brandl3ee81df2008-05-17 18:14:43 +00006548- Removed the macfs module. It had been deprecated since Python 2.5.
6549 This lead to the deprecation of macostools.touched() as it relied
6550 solely on macfs and was a no-op under OS X.
