Benjamin Petersonc0ba8282009-08-15 22:59:21 +000015- Issue #6704: Improve the col_offset in AST for "for" statements with
16 a target of tuple unpacking.
17

51
Benjamin Petersona72be3b2009-06-13 20:23:33 +000052- When no module is given in a relative import, the module field of the
53 ImportFrom AST node is now None instead of an empty string.
54

Benjamin Peterson95e5ebe2009-07-12 23:56:18 +000061 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +000062
Raymond Hettinger578a2282009-05-29 04:58:52 +000063- Issue #5982: staticmethod and classmethod now expose the wrapped
64 function with __func__.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +000069- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
70 statement and correctly lookup the __enter__ and __exit__ special methods.
71
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000072- Issue #5829: complex("1e500") no longer raises OverflowError. This
73 makes it consistent with float("1e500") and interpretation of real
74 and imaginary literals.
75
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +000076- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
77
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +000078- __instancecheck__ and __subclasscheck__ are now completely ignored on classic

82
Mark Dickinsonb1d45852009-05-11 15:33:08 +000083- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
84 (1) inf and nan strings with trailing whitespace were incorrectly
85 rejected; (2) parsing of strings representing infinities and nans
86 was locale aware; and (3) the interpretation of fromhex('-nan')
87 didn't match that of float('-nan').
88
Eric Smitha985a3a2009-05-05 18:26:08 +000089- Issue #5920: For float.__format__, change the behavior with the
90 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
91 to be like 'g' but with at least one decimal point and with a
92 default precision of 12. Previously, the behavior the same but with
93 a default precision of 6. This more closely matches str(), and
94 reduces surprises when adding alignment flags to the empty
95 presentation type. This also affects the new complex.__format__ in
96 the same way.
97
R. David Murray7ba8e1c2009-05-04 22:16:24 +000098- Issue #5890: in subclasses of 'property' the __doc__ attribute was
99 shadowed by classtype's, even if it was None. property now
100 inserts the __doc__ into the subclass instance __dict__.
101
Antoine Pitrou653dece2009-05-04 18:32:32 +0000102- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

104
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000105- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000106 format(complex(1, 2./3), '.5') now produces a sensible result.
107
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000108- Issue #5864: Fix empty format code formatting for floats so that it
109 never gives more than the requested number of significant digits.
110
Eric Smithcac7af62009-04-27 19:04:37 +0000111- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
112 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
113
Martin v. Löwis99f27792009-04-26 00:53:18 +0000114- Issue #4971: Fix titlecase for characters that are their own
115 titlecase, but not their own uppercase.
116
Eric Smith068f0652009-04-25 21:40:15 +0000117- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
118 _PyOS_double_to_string or PyOS_double_to_string.
119
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000120- Issue #5283: Setting __class__ in __del__ caused a segfault.
121
Mark Dickinson95bc9802009-04-24 12:46:53 +0000122- Issue #5816: complex(repr(z)) now recovers z exactly, even when
123 z involves nans, infs or negative zeros.
124
Eric Smithaca19e62009-04-22 13:29:05 +0000125- Implement PEP 378, Format Specifier for Thousands Separator, for
126 floats, ints, and longs.
127
128- Issue #5515: 'n' formatting for ints, longs, and floats handles
129 leading zero formatting poorly.
130
131- Issue #5772: For float.__format__, don't add a trailing ".0" if
132 we're using no type code and we have an exponent.
133
Mark Dickinson6736cf82009-04-20 21:13:33 +0000134- Issue #3166: Make long -> float (and int -> float) conversions
135 correctly rounded.
136
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000137- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
138 some builtin types.
139
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000140- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000141 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000142
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000143- Issue #5759: float() didn't call __float__ on str subclasses.
144
Georg Brandl3c4a5462009-04-12 12:08:12 +0000145- Issue #5704: the "-3" command-line option now implies "-t".
146
R. David Murray0374a822009-04-09 21:54:50 +0000147- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
148 its clarity and its speed.
149

158 the end sys.path, for compatibility with the system install of Python.
159
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000160- Issue #4688: Add a heuristic so that tuples and dicts containing only
161 untrackable objects are not tracked by the garbage collector. This can
162 reduce the size of collections and therefore the garbage collection overhead
163 on long-running programs, depending on their particular use of datatypes.
164
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000165- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
166 improve its performance. Long divisions and remainder operations
167 are now between 50% and 150% faster.
168
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000169- Issue #4258: Make it possible to use base 2**30 instead of base
170 2**15 for the internal representation of integers, for performance
171 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
172 --enable-big-digits option to configure, which overrides the
173 default. Add sys.long_info structseq to provide information about
174 the internal format.
175
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000176- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
177 result traceback.__members__ no longer exists.)
178
Mark Dickinson6b265f12009-03-18 16:07:26 +0000179- Issue #4474: PyUnicode_FromWideChar now converts characters outside
180 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
181 and sizeof(Py_UNICODE) == 2.
182
Eric Smith6f42edb2009-03-14 11:57:26 +0000183- Issue #5237: Allow auto-numbered fields in str.format(). For
184 example: '{} {}'.format(1, 2) == '1 2'.
185
Brett Cannon6c4cff02009-03-11 04:51:06 +0000186- Issue #3652: Make the 'line' argument for warnings.showwarning() a
187 requirement. Means the DeprecationWarning from Python 2.6 can go away.
188
Eric Smithe9fb6862009-02-20 14:02:36 +0000189- Issue #5247: Improve error message when unknown format codes are
190 used when using str.format() with str, unicode, long, int, and
191 float arguments.
192
Raymond Hettinger08259e82009-02-18 23:10:19 +0000193- Running Python with the -3 option now also warns about classic division
194 for ints and longs.
195
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000196- Issue #5260: Long integers now consume less memory: average
197 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
198 on a 64-bit system.
199
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000200- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
201 rotating the object pointer by 4 bits to the right.
202
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000203- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
204 it now forces its argument to double before testing for infinity.
205
Benjamin Petersone18ef192009-01-20 14:21:16 +0000206- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
207
Georg Brandl29c6a282009-04-05 20:23:13 +0000208- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000209 were suppressing all exceptions. These include list(), filter(), map(),
210 zip(), and bytearray().
211
Benjamin Peterson596d3062009-01-19 15:42:23 +0000212- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
213 functions.
214
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000215- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

219
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000220- Issue #4935: The overflow checking code in the expandtabs() method common
221 to str, bytes and bytearray could be optimized away by the compiler, letting
222 the interpreter segfault instead of raising an error.
223
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000224- Issue #3720: Fix a crash when an iterator modifies its class and removes its

230
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000231- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
232 collecting the oldest generation) so that allocating lots of objects without
233 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000234 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000235 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

238
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000239- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
240 an existing .py counterpart, override the co_filename attributes of all
241 code objects if the original filename is obsolete (which can happen if the
242 file has been renamed, moved, or if it is accessed through different paths).
243 Patch by Ziga Seilnacht and Jean-Paul Calderone.
244
Martin v. Löwis5344c992009-01-02 20:32:55 +0000245- Issue #4075: Use OutputDebugStringW in Py_FatalError.

254 where the tp_hash and tp_dict slots are both NULL.
255
Benjamin Peterson7af65562008-12-29 17:56:58 +0000256- Issue #4764: With io.open, IOError.filename is set when trying to open a

278 context manager returns a value that cannot be converted to a bool.
279
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000280- Issue #4597: Fixed several opcodes that weren't always propagating
281 exceptions.
282
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000283- Issue #4445: Replace "sizeof(PyStringObject)" with
284 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
285 str instances. On a typical machine this saves 3 bytes of memory
286 (on average) per string allocation.
287
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000288- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

1416- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1417 AttributeError instead of RuntimeError, depending in which C API call
1418 exactly the recursion limit is exceeded. Consequently, both exception types
1419 are caught and silenced.

1435
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001436- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1437
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001438- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1439 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1440 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1441 ``printf`` function, whereas PyString_FromFormat has an independent
1442 implementation and uses "%zd" on all platforms for size_t values.
1443 This makes a difference on win64, where ``printf`` needs "%Id" to display
1444 64bit values.
1445
Benjamin Peterson97179b02008-09-09 20:55:01 +00001446- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1447 error.
1448
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001449- Issue #3777: long() applied to a float object now always return a long
1450 object; previously an int would be returned for small values. the __long__
1451 method is allowed to return either an int or a long, but the behaviour of
1452 float objects should not change to respect backward compatibility.
1453
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001454- Issue #3751: str.rpartition would perform a left-partition when called with
1455 a unicode argument.
1456
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001457- Issue #3683: Fix compilation when --without-threads is given.
1458
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001459- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001460 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001461 was correctly parsed but parsing of subsequent arguments failed.
1462
Vinay Sajip35e3b032008-09-01 14:33:59 +00001463- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001464 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1465 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1466 when given a tuple of classes as second argument, were looking up
1467 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1468 type object.
1469
Neal Norwitz18aa3882008-08-24 05:04:52 +00001470- Fix crashes on memory allocation failure found with failmalloc.
1471
1472- Fix memory leaks found with valgrind and update suppressions file.
1473
1474- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1475
1476- Fix problem using wrong name in decimal module reported by pychecker.
1477
Christian Heimes7d4c3172008-08-22 19:47:25 +00001478- Silenced another compiler warning about a used but not defined
1479 function 'stringlib_contains_obj'.

1482 ``__delslice__``.
1483
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001484- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1485 library targets in the Makefile.
1486
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001487- Issue #1204: The configure script now tests for additional libraries
1488 that may be required when linking against readline. This fixes issues
1489 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001512- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001513 return a list or None rather than a custom object.

1539 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1540 for catch_warnings() also led to an improvement in the raising of a
1541 DeprecationWarning related to warnings.warn_explicit().
1542
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001543- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001607What's New in Python 2.6 beta 3?
1608================================
1609
Barry Warsaw07a4a382008-08-21 01:15:08 +00001610*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001611
1612Core and Builtins
1613-----------------
1614
Guido van Rossumf8402962008-08-20 15:01:50 +00001615- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1616 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1617 extensions do not automatically benefit from the class attribute
1618 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1619 to their tp_flags field if they care. This is a backwards
1620 compatibility feature; in 3.0, all types will use the cache by
1621 default.
1622
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001623- Keyword arguments can now follow starred arguments. (``f(a, *args,
1624 keyword=23)`` is now valid syntax.)
1625
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001626- ctypes function pointers that are COM methods have a boolean True
1627 value again.
1628
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001629- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1630 by denying s# to parse objects that have a releasebuffer procedure,
1631 and introducing s*.
1632
Georg Brandl1e13ea92008-08-11 09:07:59 +00001633- Issue #3537: Fix an assertion failure when an empty but presized dict
1634 object was stored in the freelist.
1635
Mark Dickinsonb6467572008-08-04 21:30:09 +00001636- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1637 ValueError consistently across platforms.
1638
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001639- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1640 (64bit Unix, for example), unichr() would truncate its argument and return
1641 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1642
Neal Norwitze7d8be82008-07-31 17:17:14 +00001643- Apply security patches from Apple.
1644
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001645- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1646 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1647
Antoine Pitrou92f82162008-07-25 22:22:08 +00001648- Issue #1819: function calls with several named parameters are now on
1649 average 35% faster (as measured by pybench).
1650
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001651- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1652 the python debugger steps into a class statement: the free variables (local
1653 variables defined in an outer scope) would be deleted from the outer scope.
1654
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001655- Issue #2620: Overflow checking when allocating or reallocating memory
1656 was not always being done properly in some python types and extension
1657 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1658 all been updated to perform better checks and places in the code that
1659 would previously leak memory on the error path when such an allocation
1660 failed have been fixed.
1661

1663-------
1664
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001665- Issue #3612: Added some missing basic types in ctypes.wintypes.
1666
Benjamin Petersone977ad42008-08-20 01:42:01 +00001667- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1668 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1669
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001670- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1671 version reported by these tools does not necessarily follow the python
1672 version numbering scheme, so the module is less strict when parsing it.
1673
Nick Coghlanf70385a2008-08-18 12:42:46 +00001674- Issue #2235: Added Py3k warnings for types which will become unhashable
1675 under the stricter __hash__ inheritance rules in 3.0. Several types
1676 which did not meet the rules for hash invariants and were already
1677 unhashable in 3.0 have now been explicitly flagged as unhashable in
1678 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1679 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1680
Brett Cannon88f801d2008-08-18 00:46:22 +00001681- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1682 imported into the module but exposed as part of the module's API.
1683
Brett Cannon7b96f072008-08-18 00:41:11 +00001684- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1685
Brett Cannon46225e72008-08-18 00:36:52 +00001686- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001688- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1689
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001690- Issue #3575: Incremental decoder's decode function now takes bytearray
1691 by using 's*' instead of 't#'.
1692
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001693- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001694 fails unicode conversion on 2nd parameter. (windows only)
1695
Facundo Batista94f243a2008-08-17 03:38:39 +00001696- Issue 2464. urllib2 now supports a malformation in the URL received
1697 in a redirect.
1698
Brett Cannonabe423e2008-08-16 21:47:07 +00001699- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001700 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001701
Facundo Batistaeb90b782008-08-16 14:44:07 +00001702- Issue #2776: fixed small issue when handling an URL with double slash
1703 after a 302 response in the case of not going through a proxy.
1704
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001705- Issue #2676: in the email package, content-type parsing was hanging on
1706 pathological input because of quadratic or exponential behaviour of a

Antoine Pitroude781a42008-08-09 12:43:23 +00001750 asking for a specific length. This problem only affected files opened

1794
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001795- Issue #643841: The language reference now provides more detailed

1803
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001804*Release date: 17-Jul-2008*

1807-----------------
1808
Georg Brandl3e483f62008-07-16 22:57:41 +00001809- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1810 its methods now allow for items objects that can be converted to
1811 an integer using operator.index().
1812
Mark Dickinson64b7e502008-07-16 09:40:03 +00001813- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1814 produced a ValueError instead of giving the correct float.
1815
Eric Smitha5fa5a22008-07-16 00:11:49 +00001816- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1817 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1818
Mark Dickinson7103aa42008-07-15 19:08:33 +00001819- Issue #3008: the float type has a new instance method 'float.hex'
1820 and a new class method 'float.fromhex' to convert floating-point
1821 numbers to and from hexadecimal strings, respectively.
1822
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001823- Issue #2235: __hash__ is once again inherited by default. To allow
1824 collections.Hashable to remain meaningful in the presence of the
1825 default hash implementation (object.__hash__), it is now possible
1826 to explicit block inheritance of hash by setting __hash__=None at
1827 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1828 level.
1829
Nick Coghlanb028f502008-07-13 14:52:36 +00001830- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1831 the parent module cannot be found while performing an absolute import.
1832 This means that an incorrectly defined __package__ attribute will
1833 now only prevent relative imports in that module rather than causing
1834 all imports from that module to fail.
1835
Nick Coghlan14ff9942008-07-08 14:21:42 +00001836- Issue #2517: Allow unicode messages in Exceptions again by correctly
1837 bypassing the instance dictionary when looking up __unicode__ on
1838 new-style classes.

1841 set to a custom object whose write() method happens to install
1842 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001844- Issue #3088: Corrected a race condition in classes derived from
1845 threading.local: the first member set by a thread could be saved in
1846 another thread's dictionary.
1847
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001848- Issue #3004: Minor change to slice.indices(): the start and stop
1849 arguments are now treated identically, making the behaviour easier
1850 to describe and understand. For example, slice(None, -10,
1851 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1852 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1853 10, -1).
1854
Georg Brandl278fc502008-07-19 12:46:12 +00001855- Issue #3219: Calling a function with repeated keyword arguments,
1856 f(a=2, a=23), would not cause a syntax error. This was a regression
1857 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001858
Georg Brandl278fc502008-07-19 12:46:12 +00001859- Issue #2862: Make int and float freelist management consistent with
1860 other freelists. Changes their CompactFreeList apis into

1867 api functions without holding the GIL, which could lead to a fatal
1868 error when they failed.
1869
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001870- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001895- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1896 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001897 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001898 content-length. The problem had been corrected in the 2.4 branch, but never
1899 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001914- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1916
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001917- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Vinay Sajip9828b7e2008-06-17 11:04:02 +00002285- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002286 environment to control the '-arch' flags that are used to build
2287 an extension. This was added for compatibility with Apple's build
2288 of Python.
2289
2290- The bundled OSX-specific copy of libbffi is now in sync with the version
2291 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2292
Georg Brandl25c34082008-08-18 23:09:49 +00002293- The threading module gained aliases for names that will be removed in the

2302
Brett Cannonb61d8012008-05-11 23:39:04 +00002303- ``Lib/lib-old`` is now added to sys.path.
2304
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002305- On MacOS X it is now possible to install the framework in 64-bit
2306 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002307 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002308
2309 This is controlled by the configure argument ``--with-universal-archs``:
2310
2311 - ``--with-universal-archs=all``: install 4-way universal
2312
2313 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2314
2315 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2316
2317 This option should be used in combination with ``--enable-universalsdk=``.
2318
2319 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 +00002369- Issue #1631171: Re-implement the 'warnings' module in C (the
2370 original Python code has been kept as backup). This will allow for
2371 using the 'warning's machinery in such places as the parser where
2372 use of pure Python code is not possible. Both the ``showarning()``
2373 and ``formatwarning()`` gain an optional 'line' argument which is
2374 not called by default for backwards-compatibility reasons. Setting
2375 ``warnings.showwarning()`` to an implementation that lacks support
2376 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002401- The getpass module has been improved on Unix. It now uses /dev/tty
2402 by default and uses stderr instead of stdout. A GetPassWarning is
2403 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002418- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002419 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002439- Issue #2550: The approach used by client/server code for obtaining
2440 ports to listen on in network-oriented tests has been refined in an
2441 effort to facilitate running multiple instances of the entire
2442 regression test suite in parallel without issue.
2443 test_support.bind_port() has been fixed such that it will always
2444 return a unique port -- which wasn't always the case with the
2445 previous implementation, especially if socket options had been set
2446 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2447 new implementation of bind_port() will actually raise an exception
2448 if it is passed an AF_INET/SOCK_STREAM socket with either the
2449 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2450 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2451 the socket it's been passed. This currently only applies to
2452 Windows. This option prevents any other sockets from binding to the
2453 host/port we've bound to, thus removing the possibility of the
2454 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2455 when a second SOCK_STREAM socket binds and accepts to a host/port
2456 that's already been bound by another socket. The optional preferred
2457 port parameter to bind_port() has been removed. Under no
2458 circumstances should tests be hard coding ports!
2459
2460 test_support.find_unused_port() has also been introduced, which will
2461 pass a temporary socket object to bind_port() in order to obtain an
2462 unused port. The temporary socket object is then closed and
2463 deleted, and the port is returned. This method should only be used
2464 for obtaining an unused port in order to pass to an external program
2465 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2466 a parameter to a server-oriented class that doesn't give you direct
2467 access to the underlying socket used.
2468
2469 Finally, test_support.HOST has been introduced, which should be used
2470 for the host argument of any relevant socket calls (i.e. bind and
2471 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002472
2473 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002474 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002475 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2476 test_asynchat and test_socket_ssl.
2477
Georg Brandl3ee81df2008-05-17 18:14:43 +00002478 It is now possible for multiple instances of the regression test
2479 suite to run in parallel without issue.

2747
Fred Drakea8ee94b2008-03-01 02:45:07 +00002748- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002749 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002754
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002755- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002756 issue 215555 for a discussion.
2757
Eric Smitha73fbe72008-02-23 03:09:44 +00002758- Added the future_builtins module, which contains hex() and oct().
2759 These are the PEP 3127 version of these functions, designed to be
2760 compatible with the hex() and oct() builtins from Python 3.0. They
2761 differ slightly in their output formats from the existing, unchanged
2762 Python 2.6 builtins. The expected usage of the future_builtins
2763 module is:
2764 from future_builtins import hex, oct
2765
Eric Smith7ef40bf2008-02-20 23:34:22 +00002766- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2767 exponents for exponents with absolute value < 100. Follows C99
2768 standard. This is a change on Windows, which would use 3 digits.
2769 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2770 so that any alterations it does to the resulting string will be
2771 available in stringlib/formatter.h (for float.__format__).
2772
Eric Smith5a3c1352008-02-19 13:21:56 +00002773- Implemented PEP 3101, Advanced String Formatting. This adds a new
2774 builtin format(); a format() method for str and unicode; a
2775 __format__() method to object, str, unicode, int, long, float, and
2776 datetime; the class string.Formatter; and the C API
2777 PyObject_Format().
2778
Georg Brandl3ee81df2008-05-17 18:14:43 +00002779- Fixed several potential crashes, all caused by specially crafted
2780 __del__ methods exploiting objects in temporarily inconsistent
2781 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002782
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002783- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002784 prevent a possible crash: an Abstract Base Class would try to access
2785 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002786

2788 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002790- Clear all free lists during a gc.collect() of the highest generation
2791 in order to allow pymalloc to free more arenas. Python may give back
2792 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002793
Georg Brandl3ee81df2008-05-17 18:14:43 +00002794- Issue #2045: Fix an infinite recursion triggered when printing a
2795 subclass of collections.defaultdict, if its default_factory is set
2796 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002797
Christian Heimesf75dbef2008-02-08 00:11:31 +00002798- Fixed a minor memory leak in dictobject.c. The content of the free
2799 list was not freed on interpreter shutdown.
2800
Georg Brandl3ee81df2008-05-17 18:14:43 +00002801- Limit free list of method and builtin function objects to 256
2802 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002803
Georg Brandl3ee81df2008-05-17 18:14:43 +00002804- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2805 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002806 to compact the internal free lists of pre-allocted ints and floats.
2807
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2809 calls. Python expected the return type int but the fork familie
2810 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002811
Georg Brandl3ee81df2008-05-17 18:14:43 +00002812- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2813 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002814
Georg Brandl3ee81df2008-05-17 18:14:43 +00002815- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2816 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002817
Georg Brandl3ee81df2008-05-17 18:14:43 +00002818- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2819 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002820
Georg Brandl3ee81df2008-05-17 18:14:43 +00002821- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2822 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002823
Georg Brandl3ee81df2008-05-17 18:14:43 +00002824- Patch #1473257: generator objects gain a gi_code attribute. This is
2825 the same object as the func_code attribute of the function that
2826 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002827
Georg Brandl3ee81df2008-05-17 18:14:43 +00002828- Issue #1920: "while 0" statements were completely removed by the
2829 compiler, even in the presence of an "else" clause, which is
2830 supposed to be run when the condition is false. Now the compiler
2831 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002832
Guido van Rossumeead05f2008-01-24 18:21:02 +00002833- A few crashers fixed: weakref_in_del.py (issue #1377858);
2834 loosing_dict_ref.py (issue #1303614, test67.py);
2835 borrowed_ref_[34].py (not in tracker).
2836
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002837- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002838 suppressed while an extension is loaded by calling SetErrorMode in
2839 dynload_win.c. The error is still reported properly.
2840
Georg Brandl3ee81df2008-05-17 18:14:43 +00002841- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002842 several extension methods and modules do not work without unicode
2843 support.
2844
Georg Brandl26543b12008-01-21 18:36:51 +00002845- Issue #1882: when compiling code from a string, encoding cookies in the
2846 second line of code were not always recognized correctly.
2847
Georg Brandl14404b62008-01-19 19:27:05 +00002848- Issue #1679: "0x" was taken as a valid integer literal.
2849
Georg Brandl6caad7d2008-01-26 14:19:22 +00002850- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002851 added.
2852
Christian Heimesc94e2b52008-01-14 04:13:37 +00002853- sys.float_info / PyFloat_GetInfo: The floating point information
2854 object was converted from a dict to a specialized structseq object.
2855
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Patch #1816: Added sys.flags structseq. It exposes the status of
2857 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002858
Georg Brandl3ee81df2008-05-17 18:14:43 +00002859- Objects/structseq.c: Implemented new structseq representation. The
2860 patch makes structseqs (e.g. the return value of os.stat) more
2861 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002862
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863- Patch #1700288: added a type attribute cache that caches method
2864 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002865
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002866- Bug #1776: __import__() no longer accepts filenames on any platform.
2867 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002868
Georg Brandlaed6c662008-01-07 17:25:53 +00002869- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2870
Georg Brandl3ee81df2008-05-17 18:14:43 +00002871- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2872 envvar and sys.dont_write_bytecode attribute. All these can be set
2873 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002874
Georg Brandl3ee81df2008-05-17 18:14:43 +00002875- Improve some exception messages when Windows fails to load an
2876 extension module. Now we get for example '%1 is not a valid Win32
2877 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002878

Georg Brandl3ee81df2008-05-17 18:14:43 +00002881- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2882 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002883
Christian Heimes0a8143f2007-12-18 23:22:54 +00002884- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002885 and INF. float("nan"), float("inf") and float("-inf") now work on
2886 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002887
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Compiler now generates simpler and faster code for dictionary
2889 literals. The oparg for BUILD_MAP now indicates an estimated
2890 dictionary size. There is a new opcode, STORE_MAP, for adding
2891 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002892
Georg Brandl3ee81df2008-05-17 18:14:43 +00002893- Issue #1638: %zd configure test fails on Linux.

2909 running, and if the deallocation of its frames somehow calls the
2910 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002911

Georg Brandl3ee81df2008-05-17 18:14:43 +00002920- Patch #1739468: Directories and zipfiles containing a __main__.py
2921 file can now be directly executed by passing their name to the
2922 interpreter. The directory/zipfile is automatically inserted as the
2923 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002924
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925- Issue #1265: Fix a problem with sys.settrace, if the tracing
2926 function uses a generator expression when at the same time the
2927 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002928
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002929- sets and frozensets now have an isdisjoint() method.
2930

2932
Neal Norwitz44f326e2007-10-05 05:29:17 +00002933- Fix warnings found by the new version of the Coverity checker.
2934
Georg Brandl3ee81df2008-05-17 18:14:43 +00002935- The enumerate() builtin function is no longer bounded to sequences
2936 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2937 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002938
Georg Brandl3ee81df2008-05-17 18:14:43 +00002939- Issue #1686386: Tuple's tp_repr did not take into account the
2940 possibility of having a self-referential tuple, which is possible
2941 from C code. Nor did object's tp_str consider that a type's tp_str
2942 could do something that could lead to an inifinite recursion.
2943 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2944 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002945
Georg Brandl3ee81df2008-05-17 18:14:43 +00002946- Issue #1164: It was possible to trigger deadlock when using the
2947 'print' statement to write to a file since the GIL was not released
2948 as needed. Now PyObject_Print() does the right thing along with
2949 various tp_print implementations of the built-in types and those in
2950 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002951
Georg Brandl3ee81df2008-05-17 18:14:43 +00002952- Issue #1147: Exceptions were directly allowing string exceptions in
2953 their throw() method even though string exceptions no longer
2954 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002955
Georg Brandl3ee81df2008-05-17 18:14:43 +00002956- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002958
Brett Cannon1e534b52007-09-07 04:18:30 +00002959- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002960 PyObject_Call() never calling back out to Python code to trigger
2961 recursion depth updates/checks. Required the creation of a static
2962 RuntimeError instance in case normalizing an exception put the
2963 recursion check value past its limit. Fixes crashers
2964 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002965

Neal Norwitz0ac60192007-05-27 04:08:54 +00002979- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980 __*__ attributes. (Some already existed, e.g., __doc__ and
2981 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002982
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002983- Add -3 option to the interpreter to warn about features that are
2984 deprecated and will be changed/removed in Python 3.0.
2985
Georg Brandl2134e752007-05-21 20:34:16 +00002986- Patch #1686487: you can now pass any mapping after '**' in function
2987 calls.
2988
Collin Winter62903052007-05-18 23:11:24 +00002989- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002990 "except E as target:". This is to provide forwards compatibility
2991 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002992
Brett Cannon229cee22007-05-05 01:34:02 +00002993- Deprecate BaseException.message as per PEP 352.
2994
Georg Brandl3ee81df2008-05-17 18:14:43 +00002995- Issue #1303614: don't expose object's __dict__ when the dict is

2997
Vinay Sajip8549ce32007-05-06 17:53:37 +00002998- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002999 setting a plain string, ie don't expand to single letter identifiers.
3000
Raymond Hettinger13936692007-04-11 18:40:58 +00003001- Request #1191699: Slices can now be pickled.
3002
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003003- Request #1193128: str.translate() now allows a None argument for
3004 translations that only remove characters without re-mapping the
3005 remaining characters.
3006
Georg Brandl5cb76c12007-03-21 09:00:39 +00003007- Patch #1682205: a TypeError while unpacking an iterable is no longer
3008 masked by a generic one with the message "unpack non-sequence".
3009
Neal Norwitzaa754b72007-03-21 06:39:48 +00003010- Remove unused file Python/fmod.c.
3011
Guido van Rossum143b5642007-03-23 04:58:42 +00003012- Bug #1683368: The object.__init__() and object.__new__() methods are
3013 now stricter in rejecting excess arguments. The only time when
3014 either allows excess arguments is when it is not overridden and the
3015 other one is. For backwards compatibility, when both are
3016 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003017 warning later). Also, type.__init__() insists on the same signature
3018 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003020- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3021 object to complex using its __complex__() method before falling back
3022 to the __float__() method. Therefore, the functions in the cmath
3023 module now can operate on objects that define a __complex__()
3024 method.

3044
Georg Brandl871f1bc2007-03-12 13:17:36 +00003045- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003046 its argument, if it exists. If not, it will work like before. This
3047 allows customizing the output of dir() in the presence of a
3048 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003060- Patch #703779: unset __file__ in __main__ after running a file. This

3131 embedded in the string to convert.
3132

Georg Brandl3ee81df2008-05-17 18:14:43 +00003613 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00004098 time so that opening a database previously created with the DB_DUP
4099 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4100 opens. Specifically: dictionary assignment to a DB object will
4101 replace all values for a given key when the database allows
4102 duplicate values. DB users should use DB.put(k, v) when they want
4103 to store duplicates; not DB[k] = v.

4112 behavior of quoting dots if they are the second character of any
4113 line.
