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

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

Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000468- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
469 start byte and the continuation byte(s) are now considered invalid, instead
470 of the number of bytes specified by the start byte.
471 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
472 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
473 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

483 objects. (1) The comparison could incorrectly return True in some cases
484 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000626- Issue #1533: Fix inconsistency in range function argument processing: any
627 non-float non-integer argument is now converted to an integer (if possible)
628 using its __int__ method. Previously, only small arguments were treated this
629 way; larger arguments (those whose __int__ was outside the range of a C long)
630 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +0000680- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
681 operation raises multiple signals and more than one of those signals is
682 trapped, the specification determines the order in which the signals should be
683 handled. In many cases this order wasn't being followed, leading to the wrong

870 with a non-empty format string. This is an effort to future-proof user
871 code. If a derived class does not currently implement __format__ but later
872 adds its own __format__, it would most likely break user code that had
873 supplied a format string. This will be changed to a DeprecationWaring in
874 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00001363 file position when calling `truncate()`. It would previously change the file
1364 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001365 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1368 class used to represent files stored inside an archive. The new
1369 implementation is significantly faster and can be wrapped in a
1370 ``io.BufferedReader`` object for more speedups. It also solves an issue
1371 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1460-----------------
1461
Georg Brandlba83f822010-03-14 09:50:54 +00001462- The ``__complex__()`` method is now looked up on the class of instances to
1463 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001465- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1466 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1467
Mark Dickinson1b34d252010-01-01 17:27:30 +00001468- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001469 DeprecationWarning when passed a float argument where an integer was expected.
1470 These functions and methods now raise TypeError instead. The majority of the
1471 effects of this change are in the extension modules, but some core functions
1472 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1473 and many unicode/str methods.

1484 used to drop the time part of the result.
1485
Georg Brandlba83f822010-03-14 09:50:54 +00001486- Issue #1811: Improve accuracy and cross-platform consistency for true division
1487 of integers: the result of a/b is now correctly rounded for ints a and b (at
1488 least on IEEE 754 platforms), and in particular does not depend on the
1489 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001496 executables on OSX.
1497
Georg Brandlba83f822010-03-14 09:50:54 +00001498 These executables now work properly with the arch(1) command: ``arch -ppc
1499 python`` will start a universal binary version of python in PPC mode (unlike
1500 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001656- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1657 decimal string that's guaranteed to round back to x under correct rounding
1658 (with round-half-to-even rounding mode). Previously it gave a string based on
1659 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1660 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1661 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001662
Georg Brandlba83f822010-03-14 09:50:54 +00001663- Issue #7117: On almost all platforms: float-to-string and string-to-float
1664 conversions within Python are now correctly rounded. Places these conversions
1665 occur include: str for floats and complex numbers; the float and complex
1666 constructors; old-style and new-style numeric formatting; serialization and
1667 deserialization of floats and complex numbers using marshal, pickle and json;
1668 parsing of float and imaginary literals in Python code; Decimal-to-float
1669 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001670
Georg Brandlba83f822010-03-14 09:50:54 +00001671 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1672 providing correctly-rounded strtod and dtoa C functions. This code is
1673 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1674 the C compiler. There may be a small number of platforms on which correct
1675 operation of this code cannot be guaranteed, so the code is not used: notably,
1676 this applies to platforms where the C double format is not IEEE 754 binary64,
1677 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1678 and Python's configure script is unable to determine how to change the FPU
1679 precision. On these platforms conversions use the platform strtod and dtoa,
1680 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001682- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1683 uses the correctly-rounded string <-> float conversions described above (when
1684 available), and so produces correctly rounded results that will display nicely
1685 under the float repr. There are two related small changes: (1) round now
1686 accepts any class with an ``__index__()`` method for its second argument (but
1687 no longer accepts floats for the second argument), and (2) an excessively
1688 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1689 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001836- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1837 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1838 but with at least one decimal point and with a default precision
1839 of 12. Previously, the behavior the same but with a default precision of 6.
1840 This more closely matches ``str()``, and reduces surprises when adding
1841 alignment flags to the empty presentation type. This also affects the new
1842 complex.__format__ in the same way.

2032 instead of throwing a MemoryError.
2033
Georg Brandlba83f822010-03-14 09:50:54 +00002034- Issue #3689: The list reversed iterator now supports __length_hint__ instead

2039
Georg Brandlba83f822010-03-14 09:50:54 +00002040- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2041 file objects with closefd=False. The file descriptor is still kept open but
2042 the file object behaves like a closed file. The ``FileIO`` object also got a
2043 new readonly attribute ``closefd``.

2062
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002063- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002066- On windows, ``os.chdir()`` given unicode was not working if
2067 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2068 this code path is really executed because I cannot move to such directory on
2069 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002070
Georg Brandlba83f822010-03-14 09:50:54 +00002071- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2072 element is temporarily replaced with an equivalent frozenset. But the
2073 eventual KeyError would always report the empty ``frozenset()`` as the missing
2074 key. Now it correctly refers to the initial element.

2092 returned them on 64bit platforms.
2093
Walter Dörwalded960ac2009-05-03 22:36:33 +00002094- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2095 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2096 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2097 of using the replace error handler in PyUnicode_DecodeUTF8().
2098
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002099- Issue #3739: The unicode-internal encoder now reports the number of characters
2100 consumed like any other encoder (instead of the number of bytes).
2101
Georg Brandlba83f822010-03-14 09:50:54 +00002102- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2103 allocator will be automatically disabled when running under Valgrind. This
2104 gives improved memory leak detection when running under Valgrind, while taking
2105 advantage of pymalloc at other times.

3272 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3273 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003470- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3471
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003472- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3473 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3474 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3475 ``printf`` function, whereas PyString_FromFormat has an independent
3476 implementation and uses "%zd" on all platforms for size_t values.
3477 This makes a difference on win64, where ``printf`` needs "%Id" to display
3478 64bit values.
3479
Benjamin Peterson97179b02008-09-09 20:55:01 +00003480- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3484 object; previously an int would be returned for small values. the __long__
3485 method is allowed to return either an int or a long, but the behaviour of
3486 float objects should not change to respect backward compatibility.
3487
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003488- Issue #3751: str.rpartition would perform a left-partition when called with
3489 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00003494 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003495 was correctly parsed but parsing of subsequent arguments failed.
3496
Vinay Sajip35e3b032008-09-01 14:33:59 +00003497- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003498 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3499 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3500 when given a tuple of classes as second argument, were looking up
3501 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3502 type object.
3503
Neal Norwitz18aa3882008-08-24 05:04:52 +00003504- Fix crashes on memory allocation failure found with failmalloc.

3647-----------------
3648
Guido van Rossumf8402962008-08-20 15:01:50 +00003649- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3650 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3651 extensions do not automatically benefit from the class attribute
3652 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3653 to their tp_flags field if they care. This is a backwards
3654 compatibility feature; in 3.0, all types will use the cache by
3655 default.
3656
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003657- Keyword arguments can now follow starred arguments. (``f(a, *args,
3658 keyword=23)`` is now valid syntax.)
3659
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003660- ctypes function pointers that are COM methods have a boolean True
3661 value again.
3662
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003663- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,

3665 and introducing s*.
3666
Georg Brandl1e13ea92008-08-11 09:07:59 +00003667- Issue #3537: Fix an assertion failure when an empty but presized dict
3668 object was stored in the freelist.
3669
Mark Dickinsonb6467572008-08-04 21:30:09 +00003670- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3671 ValueError consistently across platforms.
3672
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003673- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3674 (64bit Unix, for example), unichr() would truncate its argument and return
3675 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3676
Neal Norwitze7d8be82008-07-31 17:17:14 +00003677- Apply security patches from Apple.
3678
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003679- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

3681
Antoine Pitrou92f82162008-07-25 22:22:08 +00003682- Issue #1819: function calls with several named parameters are now on
3683 average 35% faster (as measured by pybench).
3684
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003685- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3686 the python debugger steps into a class statement: the free variables (local
3687 variables defined in an outer scope) would be deleted from the outer scope.
3688
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003689- Issue #2620: Overflow checking when allocating or reallocating memory
3690 was not always being done properly in some python types and extension
3691 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3692 all been updated to perform better checks and places in the code that
3693 would previously leak memory on the error path when such an allocation
3694 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00003701- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3702 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3703
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003704- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3705 version reported by these tools does not necessarily follow the python
3706 version numbering scheme, so the module is less strict when parsing it.
3707
Nick Coghlanf70385a2008-08-18 12:42:46 +00003708- Issue #2235: Added Py3k warnings for types which will become unhashable
3709 under the stricter __hash__ inheritance rules in 3.0. Several types
3710 which did not meet the rules for hash invariants and were already
3711 unhashable in 3.0 have now been explicitly flagged as unhashable in
3712 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3713 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3714
Brett Cannon88f801d2008-08-18 00:46:22 +00003715- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3716 imported into the module but exposed as part of the module's API.
3717
Brett Cannon7b96f072008-08-18 00:41:11 +00003718- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3719

3721
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003722- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3723
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003724- Issue #3575: Incremental decoder's decode function now takes bytearray
3725 by using 's*' instead of 't#'.
3726
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003727- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003728 fails unicode conversion on 2nd parameter. (windows only)
3729
Georg Brandl222e2082010-08-01 22:27:39 +00003730- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003731 in a redirect.
3732
Brett Cannonabe423e2008-08-16 21:47:07 +00003733- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003734 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003735
Facundo Batistaeb90b782008-08-16 14:44:07 +00003736- Issue #2776: fixed small issue when handling an URL with double slash
3737 after a 302 response in the case of not going through a proxy.
3738
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003739- Issue #2676: in the email package, content-type parsing was hanging on
3740 pathological input because of quadratic or exponential behaviour of a
3741 regular expression.
3742
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003743- Issue #3476: binary buffered reading through the new "io" library is now
3744 thread-safe.
3745
Brett Cannonbf3157b2008-08-14 05:00:03 +00003746- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3747 since mimetools itself is deprecated. Because modules are cached, all
3748 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3749
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003750- Issue #3134: shutil referenced undefined WindowsError symbol.

3753 menu entries were not deleted.
3754
Brett Cannon83e81842008-08-09 23:30:55 +00003755- Copied the implementation of reduce() to _functools.reduce() to have a

3757
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003758- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3759 a MemoryError rather than silently stop the iteration.
3760
Guido van Rossum59ce9012008-08-09 14:55:34 +00003761- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3762 to _sre.compile() will now be rejected. This should not affect anybody
3763 since the re.compile() function never generates invalid re-bytecode.
3764
Skip Montanaroa032bf42008-08-08 22:52:51 +00003765- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3766 upon first access it can be automatically initialized from the csv file if
3767 it wasn't initialized during instantiation.
3768
Brett Cannon3aa2a492008-08-06 22:28:09 +00003769- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3770 the reload() built-in has been removed.
3771
Brett Cannon7e30b672008-08-04 21:52:25 +00003772- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003773 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3781 raised an AttributeError.
3782
Benjamin Peterson01a24322008-07-28 23:35:27 +00003783- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003784 asking for a specific length. This problem only affected files opened
3785 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003786

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003810- Issue #3394: zipfile.writestr sets external attributes when passed a
3811 file name rather than a ZipInfo instance, so files are extracted with
3812 mode 0600 rather than 000 under Unix.
3813
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003814- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3827 interaction with the tp_hash slot (added in 2.6b2) are now documented
3828
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003829- Issue #643841: The language reference now provides more detailed
3830 coverage of the lookup process for special methods. The disclaimers
3831 regarding lack of coverage of new-style classes have also been
3832 removed, since the coverage is now fairly reasonable.

3836================================
3837
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003838*Release date: 17-Jul-2008*
3839
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003840Core and Builtins
3841-----------------
3842
Georg Brandl3e483f62008-07-16 22:57:41 +00003843- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3844 its methods now allow for items objects that can be converted to
3845 an integer using operator.index().
3846
Mark Dickinson64b7e502008-07-16 09:40:03 +00003847- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3848 produced a ValueError instead of giving the correct float.
3849
Eric Smitha5fa5a22008-07-16 00:11:49 +00003850- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3851 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3852
Mark Dickinson7103aa42008-07-15 19:08:33 +00003853- Issue #3008: the float type has a new instance method 'float.hex'
3854 and a new class method 'float.fromhex' to convert floating-point
3855 numbers to and from hexadecimal strings, respectively.
3856
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003857- Issue #2235: __hash__ is once again inherited by default. To allow
3858 collections.Hashable to remain meaningful in the presence of the
3859 default hash implementation (object.__hash__), it is now possible
3860 to explicit block inheritance of hash by setting __hash__=None at
3861 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3862 level.
3863
Nick Coghlanb028f502008-07-13 14:52:36 +00003864- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3865 the parent module cannot be found while performing an absolute import.
3866 This means that an incorrectly defined __package__ attribute will
3867 now only prevent relative imports in that module rather than causing
3868 all imports from that module to fail.
3869
Nick Coghlan14ff9942008-07-08 14:21:42 +00003870- Issue #2517: Allow unicode messages in Exceptions again by correctly
3871 bypassing the instance dictionary when looking up __unicode__ on
3872 new-style classes.
3873
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003874- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3875 set to a custom object whose write() method happens to install
3876 another file in sys.stdout.
3877
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003878- Issue #3088: Corrected a race condition in classes derived from
3879 threading.local: the first member set by a thread could be saved in
3880 another thread's dictionary.
3881
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003882- Issue #3004: Minor change to slice.indices(): the start and stop
3883 arguments are now treated identically, making the behaviour easier
3884 to describe and understand. For example, slice(None, -10,
3885 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3886 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3887 10, -1).
3888
Georg Brandl278fc502008-07-19 12:46:12 +00003889- Issue #3219: Calling a function with repeated keyword arguments,
3890 f(a=2, a=23), would not cause a syntax error. This was a regression
3891 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003892
Georg Brandl278fc502008-07-19 12:46:12 +00003893- Issue #2862: Make int and float freelist management consistent with
3894 other freelists. Changes their CompactFreeList apis into
3895 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003900- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3901 api functions without holding the GIL, which could lead to a fatal
3902 error when they failed.
3903
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003904- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Vinay Sajip51e65192008-07-18 09:01:10 +00003915- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003929- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3930 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003931 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003932 content-length. The problem had been corrected in the 2.4 branch, but never
3933 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003948- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3950
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003951- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

4340 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004341 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004342
4343 This is controlled by the configure argument ``--with-universal-archs``:
4344
4345 - ``--with-universal-archs=all``: install 4-way universal
4346
4347 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4348
4349 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4350
4351 This option should be used in combination with ``--enable-universalsdk=``.
4352
4353 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 +00004403- Issue #1631171: Re-implement the 'warnings' module in C (the
4404 original Python code has been kept as backup). This will allow for
4405 using the 'warning's machinery in such places as the parser where
4406 use of pure Python code is not possible. Both the ``showarning()``
4407 and ``formatwarning()`` gain an optional 'line' argument which is
4408 not called by default for backwards-compatibility reasons. Setting
4409 ``warnings.showwarning()`` to an implementation that lacks support
4410 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004473- Issue #2550: The approach used by client/server code for obtaining
4474 ports to listen on in network-oriented tests has been refined in an
4475 effort to facilitate running multiple instances of the entire
4476 regression test suite in parallel without issue.
4477 test_support.bind_port() has been fixed such that it will always
4478 return a unique port -- which wasn't always the case with the
4479 previous implementation, especially if socket options had been set
4480 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4481 new implementation of bind_port() will actually raise an exception
4482 if it is passed an AF_INET/SOCK_STREAM socket with either the
4483 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4484 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4485 the socket it's been passed. This currently only applies to
4486 Windows. This option prevents any other sockets from binding to the
4487 host/port we've bound to, thus removing the possibility of the
4488 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4489 when a second SOCK_STREAM socket binds and accepts to a host/port
4490 that's already been bound by another socket. The optional preferred
4491 port parameter to bind_port() has been removed. Under no
4492 circumstances should tests be hard coding ports!
4493
4494 test_support.find_unused_port() has also been introduced, which will
4495 pass a temporary socket object to bind_port() in order to obtain an
4496 unused port. The temporary socket object is then closed and
4497 deleted, and the port is returned. This method should only be used
4498 for obtaining an unused port in order to pass to an external program
4499 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4500 a parameter to a server-oriented class that doesn't give you direct
4501 access to the underlying socket used.
4502
4503 Finally, test_support.HOST has been introduced, which should be used
4504 for the host argument of any relevant socket calls (i.e. bind and
4505 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004506
4507 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004508 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004509 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4510 test_asynchat and test_socket_ssl.
4511
Georg Brandl3ee81df2008-05-17 18:14:43 +00004512 It is now possible for multiple instances of the regression test
4513 suite to run in parallel without issue.

Christian Heimes5224d282008-02-23 15:01:05 +00004788
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004789- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00004790 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00004791
Eric Smitha73fbe72008-02-23 03:09:44 +00004792- Added the future_builtins module, which contains hex() and oct().
4793 These are the PEP 3127 version of these functions, designed to be
4794 compatible with the hex() and oct() builtins from Python 3.0. They
4795 differ slightly in their output formats from the existing, unchanged
4796 Python 2.6 builtins. The expected usage of the future_builtins
4797 module is:
4798 from future_builtins import hex, oct
4799
Eric Smith7ef40bf2008-02-20 23:34:22 +00004800- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4801 exponents for exponents with absolute value < 100. Follows C99
4802 standard. This is a change on Windows, which would use 3 digits.
4803 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4804 so that any alterations it does to the resulting string will be
4805 available in stringlib/formatter.h (for float.__format__).
4806
Eric Smith5a3c1352008-02-19 13:21:56 +00004807- Implemented PEP 3101, Advanced String Formatting. This adds a new
4808 builtin format(); a format() method for str and unicode; a
4809 __format__() method to object, str, unicode, int, long, float, and
4810 datetime; the class string.Formatter; and the C API
4811 PyObject_Format().
4812
Georg Brandl3ee81df2008-05-17 18:14:43 +00004813- Fixed several potential crashes, all caused by specially crafted
4814 __del__ methods exploiting objects in temporarily inconsistent
4815 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004816
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004817- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004818 prevent a possible crash: an Abstract Base Class would try to access
4819 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004820
Georg Brandl3ee81df2008-05-17 18:14:43 +00004821- Fixed repr() and str() of complex numbers with infinity or nan as
4822 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004823
Georg Brandl3ee81df2008-05-17 18:14:43 +00004824- Clear all free lists during a gc.collect() of the highest generation
4825 in order to allow pymalloc to free more arenas. Python may give back
4826 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004827
Georg Brandl3ee81df2008-05-17 18:14:43 +00004828- Issue #2045: Fix an infinite recursion triggered when printing a
4829 subclass of collections.defaultdict, if its default_factory is set
4830 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004831
Christian Heimesf75dbef2008-02-08 00:11:31 +00004832- Fixed a minor memory leak in dictobject.c. The content of the free
4833 list was not freed on interpreter shutdown.
4834
Georg Brandl21e99f42010-03-07 15:23:59 +00004835- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004836 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004837
Georg Brandl3ee81df2008-05-17 18:14:43 +00004838- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4839 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004840 to compact the internal free lists of pre-allocted ints and floats.
4841
Georg Brandl3ee81df2008-05-17 18:14:43 +00004842- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4843 calls. Python expected the return type int but the fork familie
4844 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004845
Georg Brandl3ee81df2008-05-17 18:14:43 +00004846- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4847 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004848
Georg Brandl3ee81df2008-05-17 18:14:43 +00004849- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4850 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004851
Georg Brandl3ee81df2008-05-17 18:14:43 +00004852- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4853 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004854
Georg Brandl3ee81df2008-05-17 18:14:43 +00004855- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4856 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004857
Georg Brandl3ee81df2008-05-17 18:14:43 +00004858- Patch #1473257: generator objects gain a gi_code attribute. This is
4859 the same object as the func_code attribute of the function that
4860 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004861
Georg Brandl3ee81df2008-05-17 18:14:43 +00004862- Issue #1920: "while 0" statements were completely removed by the
4863 compiler, even in the presence of an "else" clause, which is
4864 supposed to be run when the condition is false. Now the compiler
4865 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004866
Guido van Rossumeead05f2008-01-24 18:21:02 +00004867- A few crashers fixed: weakref_in_del.py (issue #1377858);
4868 loosing_dict_ref.py (issue #1303614, test67.py);
4869 borrowed_ref_[34].py (not in tracker).
4870
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004871- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004872 suppressed while an extension is loaded by calling SetErrorMode in
4873 dynload_win.c. The error is still reported properly.
4874
Georg Brandl3ee81df2008-05-17 18:14:43 +00004875- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004876 several extension methods and modules do not work without unicode
4877 support.
4878
Georg Brandl26543b12008-01-21 18:36:51 +00004879- Issue #1882: when compiling code from a string, encoding cookies in the
4880 second line of code were not always recognized correctly.
4881
Georg Brandl14404b62008-01-19 19:27:05 +00004882- Issue #1679: "0x" was taken as a valid integer literal.
4883
Georg Brandl6caad7d2008-01-26 14:19:22 +00004884- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004885 added.
4886
Christian Heimesc94e2b52008-01-14 04:13:37 +00004887- sys.float_info / PyFloat_GetInfo: The floating point information
4888 object was converted from a dict to a specialized structseq object.
4889
Georg Brandl3ee81df2008-05-17 18:14:43 +00004890- Patch #1816: Added sys.flags structseq. It exposes the status of
4891 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004892
Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Objects/structseq.c: Implemented new structseq representation. The
4894 patch makes structseqs (e.g. the return value of os.stat) more
4895 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004896
Georg Brandl3ee81df2008-05-17 18:14:43 +00004897- Patch #1700288: added a type attribute cache that caches method
4898 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004899
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004900- Bug #1776: __import__() no longer accepts filenames on any platform.
4901 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004902
Georg Brandlaed6c662008-01-07 17:25:53 +00004903- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4904
Georg Brandl3ee81df2008-05-17 18:14:43 +00004905- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4906 envvar and sys.dont_write_bytecode attribute. All these can be set
4907 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004908
Georg Brandl3ee81df2008-05-17 18:14:43 +00004909- Improve some exception messages when Windows fails to load an
4910 extension module. Now we get for example '%1 is not a valid Win32
4911 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004912
Georg Brandl3ee81df2008-05-17 18:14:43 +00004913- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004915- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4916 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004917
Christian Heimes0a8143f2007-12-18 23:22:54 +00004918- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004919 and INF. float("nan"), float("inf") and float("-inf") now work on
4920 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004921
Georg Brandl3ee81df2008-05-17 18:14:43 +00004922- Compiler now generates simpler and faster code for dictionary
4923 literals. The oparg for BUILD_MAP now indicates an estimated
4924 dictionary size. There is a new opcode, STORE_MAP, for adding
4925 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00004926
Georg Brandl3ee81df2008-05-17 18:14:43 +00004927- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004932- Issue #1538: Avoid copying string in split/rsplit if the split char
4933 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00004934
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00004935- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00004936 SystemError.
4937
Nick Coghlanef01d822007-12-03 12:55:17 +00004938- PEP 366: Allow explicit relative imports when executing modules

4940 __package__ attribute.
4941
Georg Brandl3ee81df2008-05-17 18:14:43 +00004942- Issue #1402: Fix a crash on exit, when another thread is still
4943 running, and if the deallocation of its frames somehow calls the
4944 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00004945

4955 file can now be directly executed by passing their name to the
4956 interpreter. The directory/zipfile is automatically inserted as the
4957 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004958
Georg Brandl3ee81df2008-05-17 18:14:43 +00004959- Issue #1265: Fix a problem with sys.settrace, if the tracing
4960 function uses a generator expression when at the same time the
4961 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004962
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004963- sets and frozensets now have an isdisjoint() method.
4964
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004965- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00004967- Fix warnings found by the new version of the Coverity checker.
4968
Georg Brandl21e99f42010-03-07 15:23:59 +00004969- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004970 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4971 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004972
Georg Brandl3ee81df2008-05-17 18:14:43 +00004973- Issue #1686386: Tuple's tp_repr did not take into account the
4974 possibility of having a self-referential tuple, which is possible
4975 from C code. Nor did object's tp_str consider that a type's tp_str
4976 could do something that could lead to an inifinite recursion.
4977 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4978 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004979
Georg Brandl3ee81df2008-05-17 18:14:43 +00004980- Issue #1164: It was possible to trigger deadlock when using the
4981 'print' statement to write to a file since the GIL was not released
4982 as needed. Now PyObject_Print() does the right thing along with
4983 various tp_print implementations of the built-in types and those in
4984 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004985
Georg Brandl3ee81df2008-05-17 18:14:43 +00004986- Issue #1147: Exceptions were directly allowing string exceptions in
4987 their throw() method even though string exceptions no longer
4988 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004989

Brett Cannon1e534b52007-09-07 04:18:30 +00004993- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004994 PyObject_Call() never calling back out to Python code to trigger
4995 recursion depth updates/checks. Required the creation of a static
4996 RuntimeError instance in case normalizing an exception put the
4997 recursion check value past its limit. Fixes crashers
4998 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004999

Neal Norwitz0ac60192007-05-27 04:08:54 +00005013- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005014 __*__ attributes. (Some already existed, e.g., __doc__ and
5015 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005016
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005017- Add -3 option to the interpreter to warn about features that are
5018 deprecated and will be changed/removed in Python 3.0.
5019
Georg Brandl2134e752007-05-21 20:34:16 +00005020- Patch #1686487: you can now pass any mapping after '**' in function
5021 calls.
5022
Collin Winter62903052007-05-18 23:11:24 +00005023- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005024 "except E as target:". This is to provide forwards compatibility
5025 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005032- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005033 setting a plain string, ie don't expand to single letter identifiers.

5039 remaining characters.
5040
Georg Brandl5cb76c12007-03-21 09:00:39 +00005041- Patch #1682205: a TypeError while unpacking an iterable is no longer

Guido van Rossum143b5642007-03-23 04:58:42 +00005046- Bug #1683368: The object.__init__() and object.__new__() methods are
5047 now stricter in rejecting excess arguments. The only time when
5048 either allows excess arguments is when it is not overridden and the
5049 other one is. For backwards compatibility, when both are
5050 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005051 warning later). Also, type.__init__() insists on the same signature
5052 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005054- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5055 object to complex using its __complex__() method before falling back
5056 to the __float__() method. Therefore, the functions in the cmath
5057 module now can operate on objects that define a __complex__()
5058 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005076- Bug #1678647: write a newline after printing an exception in any
5077 case, even when converting the value to a string failed.
5078
Georg Brandl871f1bc2007-03-12 13:17:36 +00005079- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005080 its argument, if it exists. If not, it will work like before. This
5081 allows customizing the output of dir() in the presence of a
5082 __getattr__().

5092 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00005094- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005095 makes the filenames the warning module prints much more sensible
5096 when a PYTHONSTARTUP file is used.

5110 sq_ass_slice instead of the sq_slice slot.
5111
Georg Brandl3ee81df2008-05-17 18:14:43 +00005112- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00005215 generator expressions (x for x, in ... ) works again. Fixing this
5216 problem required changing the .pyc magic number. This means that
5217 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006024- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6025 with RFC 3207 and forgets any knowledge obtained from the server not
6026 obtained from the TLS negotiation itself. Patch contributed by Bill
6027 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006028
Georg Brandl3ee81df2008-05-17 18:14:43 +00006029- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006030 that the SMTP.starttls() caller no longer needs to call ehlo()
6031 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006032 does not claim to support starttls. Adds the
6033 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6034 Fenner.

6114 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6115 silently miscode subclasses of those types. Now, it raises a
6116 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006117

Georg Brandl3ee81df2008-05-17 18:14:43 +00006132 time so that opening a database previously created with the DB_DUP
6133 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6134 opens. Specifically: dictionary assignment to a DB object will
6135 replace all values for a given key when the database allows
6136 duplicate values. DB users should use DB.put(k, v) when they want
6137 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006138

6144 characters with ASCII value less than 32. Also, it correctly quotes
6145 dots only if they occur on a single line, as opposed to the previous
6146 behavior of quoting dots if they are the second character of any
6147 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006148

Georg Brandl3ee81df2008-05-17 18:14:43 +00006553- Removed the macfs module. It had been deprecated since Python 2.5.
6554 This lead to the deprecation of macostools.touched() as it relied
6555 solely on macfs and was a no-op under OS X.
